Abstract:
We have established an HEC funded
basic Analysis Node for Bioinformatics at, Al-Khwarzmi
Institute of Computer Science, U.E.T., Lahore with the
objectives of establishing and strengthen bio/chem-informatics
infrastructure in Pakistan through linkages with international
organizations involved in R&D and manufacturing activities in
biotechnology. This paper describes the nature and objectives of
collaboration with The Broad Institute of MIT and Harvard
(http://www.broad.mit.edu) to create components of a public
database that provides transparent access to high-quality
compound probe development research data generated as part of
ongoing projects at the Broad Institute, enabling the data to be
used as effectively by outside researchers as it is by Broad
investigators. Limitations of existing ChemBank v2 and need for
ChemBank V3 as a new model of public databases is identified.

Abstract:
The purpose of this in vitro study was to compare the cyclic
fatigue resistance of ProFile GT (Dentsply Tulsa Dental, Tulsa,
OK) and ProFile GT Series X (Dentsply Tulsa Dental). Files of taper 0.04, 0.06 and 0.08, 25 mm in length, and ISO sizes # 30
were compared (n = 10 per group). Cyclic fatigue was determined
by recording the time until fracture of a file rotating in a
simulated canal with curvatures 45 º and 60 º degrees. The files
were operated in a cyclic fatigue testing device that was
especially designed and made for this test.
There was a statistically significant
difference between ProFile GT 30/4 in 45 ̊ curvature and ProFile
GTX 30/4 in 45 ̊ curvature, as well as, between ProFile GT 30/8
in curvature 45 ̊ and ProFile GTX 30/8 in curvature 45 ̊. These
differences were extremely significant for both (P < 0.001).
While for ProFile GT 30/6 in curvature 45 ̊ and ProFile GTX
30/6 in curvature 45 ̊ the difference was not significant (P
> 0.05). In the simulated canal of 60 ̊ degrees curvature, the
differences were not statistically significant between the
tested instruments (P > 0.05).

Abstract: This
investigation was conducted for three successive seasons (2008,
2009 & 2010) in a private vineyard located at El-Khatatba,
Menoufiya governorate to description and evaluation four grape
seedless cultivars namely: Thompson Seedless clone 2A, Fiesta,
Melissa and Crimson Seedless grape cultivars under Egyptian
conditions. The chosen vines were five years old, grown in a
sandy loam soil, spaced at 2 X 3 meters apart, irrigated by the
drip system, and cane-pruned and trellised by the Spanish Parron
system. Some phenological aspects, description studies including
(growing tips, leaves, tendrils, bunches and berries), yield and
physical and chemical studies of bunches and berries and
histogical studies of percentage of predicted bud fertility at
different bud positions lengthwise the cane were carried out.
The results revealed that Thompson Seedless clone 2A and Fiesta
grape varieties were the earliest varieties giving the lowest
number of days with regard to the phenological dates (budburst,
full bloom, fruit set, veraison and grape maturity) compared to
Melissa and Crimson Seedless grape varieties which were the
latest in this respect having the highest number of days through
the three seasons of the study. All studied cultivars were
characterized by good vegetative growth and bunch quality. The
average bunch weight of Crimson Seedless cultivar was medium,
whereas it was big in Thompson Seedless clone 2A, Fiesta and
Melissa cultivars. Concerning berry weight and size, Thompson
Seedless clone 2A and Fiesta cultivars were medium, while,
Melissa and Crimson Seedless cultivars were big. As for the
berry shape, Thompson Seedless clone 2A and Fiesta cultivars
were rounded- spherical, while, Melissa and Crimson Seedless
cultivars were oval–cylindrical. Concerning berry colour, it is
clear that in Thompson Seedless clone 2A cultivar it was yellow,
greenish yellow in Fiesta cultivar, yellowish green in Melissa
cultivar and bright red in Crimson Seedless cultivar. Percentage
of predicted bud fertility at different bud positions lengthwise
the cane increased gradually from the basal buds to the middle
buds of the cane where it reached its maximum then decreased
gradually towards the distal buds in all studied cultivars.

Abstract:
Evans Shoal Gas Field comprises the wells Evans Shoal-1and Evans
Shoal-2. Our study aimed to determine the hydrocarbon potential
of the main source rock in the study area and analyze the
petroleum systems and guide future hydrocarbon exploration and
development. The methods used encompass BasinMod techniques
using mathematical methods. Analysis of the source rock
potential helped to identify the Plover-Plover (!) system. The
main source rock and reservoir rock are located in the Plover
Formation. The source rock of Plover Formation is currently
mature and characterized by OM Type II and Type III. The average
TOC of the Plover Formation in well Evans Shoal-1 is 1.78 wt%,
whereas in well Evans Shoal-2 it is 1.84 wt%. The reservoir
composed predominantly of fine-grained sandstone deposited with
marine and estuarine environments. The measured porosity and
permeability are reduced with depth and the upper part of the
reservoir section is better than lower one. Cleia and Echuca
Shoals formations encompass the main Seal. The overburden
includes Cleia, Echuca Shoals, Darwin, Jamieson, Wangarlu, Vee,
Lynedoch, Turnestone, Hibernia, Oliver, Barracouta and Alaria
formations. The traps were developed from Middle Jurassic to
Middle Cretaceous, are almost anticline structural traps. The
threshold for hydrocarbon generation and expulsion of the Plover
Formation occurred during Late cretaceous and reached the peak
at Early Paleocene. The intensities of gas generation and
expulsion of the Plover Formation source rock are greater than
that of oil generation and expulsion. The Plover-Plover (!)
System comprises a complete geological elements and processes.

Abstract-
The
most promising and fully operational GPS (Global Positioning
System) is a navigation system based on a group of 24 satellites
developed by U.S. Department of Defence.
Every satellite
sends data to the receiver in the form of signals, having some
information about satellite and orbital information.
This paper aims to discuss the potential of GPS as constantly
global communication medium and gives insights in terms of its
business and military applications. It focuses on the
architecture of GPS, its working, changing signal conditions and
discusses its technical applicability and uses current advanced
applications of GPS like vehicle tracking, location-based
services as a case study. Even in worst weather conditions this
GPS system is used to find out exact location with respect to
timing information anywhere on the surface of globe. The paper
will also consider different weather and geographical conditions
to prove the suitability and compatibility of the GPS. The paper
will also compare GPS with other navigation systems and will
discuss its advantages such as high precision and
continuous coverage.

Abstract-
As new communication technologies are emerging they are
introducing new form of short range wireless networks. Bluetooth
is one of them as well, which allows information exchange over a
short range. Bluetooth is a low cost, short range and low power
radio technology which was originally developed to connect the
devices such as mobile phone handsets, portable computers,
headsets without having cable. Bluetooth was started in about
1994 by Ericson mobile communications but version 1.0 of
Bluetooth came out in 1999. Bluetooth is a fastest growing
technology. Its applications are increasing as the research goes
on. By using Bluetooth we can make connection for traffic
between sender and receiver. It can be either synchronous
traffic such as voice or asynchronous traffic such as traffic
over the internet protocol. In this paper we shall discuss that
how efficiently Bluetooth can carry the TCP/IP traffic and as
well as we shall analyse that how retransmission and delays are
handled when there is an error in a packet of data. In addition
we shall discuss the Bluetooth layer model and how it works and
make the comparison between OSI reference model and Bluetooth
layer model.

Abstract:
Split tensile strength of SiO2 nanoparticle blended
cementitious composite cured in saturated limewater have been
optimized. SiO2 nanoparticles with partial
replacement of cement by 0.5, 1.0, 1.5 and 2.0 weight percent
have been used as reinforcement. To determine the strength of
cement pastes, the specimens were cured in two different media
(water and saturated limewater) for 7, 28 and 90 days. The
results showed that SiO2 nanoparticles could improve
the mechanical properties of concrete. It has been obtained that
curing in saturated limewater for 28 days and afterwards in
water until 90 days, produces more strengthened cementitious
composite than those cured only in water or saturated limewater
for 90 days. Excess Ca(OH)2 crystals which forms
after 28 days when the specimens cured limewater reduces the
effect of C-S-H gels which form until the 90 days hence
negatively impacts the mechanical properties of the specimens.
On the other hand, curing the specimens in water after 28 days
produces more C-S-H gel results in a cementitious composite with
higher strength.

Abstract:
Obesity constitutes a major risk factor for both maternal and
fetal complications for mothers includes, hypertensive
disorders, gestational diabetes, preeclampsia, eclampsia and
higher frequency of cesarean section and fetal complications
includes intrauterine death, low Apgar score and macrosomia.
This study aimed to assess risk
factors of obesity on maternal and perinatal outcomes among
pregnant women. Prospective cohort study, the study
subjects consisted of four groups; 27 women with normal BMI
(group I: BMI 19.1–25 kg/m2), 25 overweight (group II: BMI
25.1–30 kg/m2), 73 obese (group III: BMI 30.1–40 kg/m2) and 25
morbidly obese women (group IV: BMI >40 kg/m2). The study was
conducted in obstetric department, labor ward at zagazig
university hospital. Women in group III and IV were
characterized by higher systolic booking blood pressure and
higher diastolic booking blood pressures, with mean differences
being 27.9,14.2 respectively. Similar differences were found in
booking diastolic blood pressures with mean difference being
12.13 and 1.83 respectively. Women in group III and IV are at
increased risk at gestational diabetes with OR 2.72; and OR
10.1. Requirement of instrumental deliveries or lower segment
caesarean section occurred more often in group II, III and IV
with 2.07, 2.58 and 6.61 respectively. The birth weight in group
III and IV are significantly higher with mean differences 1.54
and 1.72. Macrosomia occurred more often in all increased BMI
groups, but significance was only found in women of group IV
with OR 4.4. The present study had revealed that the obesity
during pregnancy represents a major risk for adverse outcome for
pregnant women. Maternal weight measurements need to be recorded
during antenatal care and used consistently because BMI is
obviously a risk factor for maternal complications during
pregnancy, labor and postpartum period.

Abstract:
In this study, dream symbols and
their effect on opinion of the poet are reviewed, and difference
between the application of this element in Shahnameh and
Kushnameh is expressed. The dreams are one of several
attractiveness factors of Iranshah stories in Kushnamh. He
expresses beautiful and mysterious stories and legends, and in
addition to respecting national and cultural values and figures,
secret of many complexities are revealed to us in the form of a
dream. His mysterious dreams have also features of Ahormazda
dreams. In addition, they carry messages that contain their
probable problems as well, which are symbolic and the truth is
hidden in secrets. Iranshah has tried to reflect the hidden
dimensions of his story characters and heroes in their dreams,
and to create images with elements of dream that never happen in
reality. He also tries to warn his readers and those who suffer
from negligence and awaken and bring them to the world of
conscious.

Abstract:
This study was performed to investigate the association between
FSH receptor (FSHR) gene polymorphism at position 680 and the
outcomes of controlled ovarian stimulation (COS) for in vitro
fertilization (IVF) in Egyptian women. The FSHR genotype
distribution was 36.6% for Asn/Asn, 31.7% for Asn/Ser, and 31.7%
for Ser/Ser FSHR genotype groups. Although there was no
difference among the three genotype groups in terms of the age
and infertility diagnosis of study subjects, the basal levels of
FSH (day 3) were significantly different [6.37 ± 1.65 mIU/ml
(mean±SEM), 6.93 ± 2.09 mIU/ml, and 8.42 ± 3.22 mIU/ml] for
Asn/Asn, Asn/Ser, and Ser/Ser groups, respectively. The Ser/Ser
group tended to require a least dose of gonadotropins for COS,
though these differences did not reach statistical significance.
When the patients were classified according to their ovarian
response, the mean levels of basal FSH in Asn/Asn and Ser/Ser
subgroups showed an increasing level from poor to good and high
responders. In contrast Asn/Ser subgroup showed a decreasing
level of day 3 FSH from poor to good and high responders,
thus indicating a relative
resistance to the action of FSH in this subgroup. The
numbers of oocytes retrieved tended to be different for the
three groups (5.47 ± 3.02, 6.54 ± 7.48, and 11.23 ± 4.48 for
Asn/Asn, Asn/Ser, and Ser/Ser groups, respectively). Clinical
pregnancy rate was higher (23.08%) in Ser/Ser, compared to the
others. The homozygous Asn/Asn genotype of FSHR polymorphism at
position 680 may be associated with a reduced ovarian response
to COS for IVF, while Ser/Ser genotypes showed a higher
pregnancy rate.

Abstract:
The present
study deals with the ultrastructure of the mature spermatozoa of
three species belonging to the land snail genus Monacha (Müller,
1774). These snails are considered as agricultural pests. These
species are M. cantiana, M. cartusiana and M. obstructa. They
are morphologically closely similar to each other. The present
investigation is a new trial to differentiate between them. The
snails were collected from the field crops at Dakahlia
governorate and brought alive to the laboratory where they were
dissected and the gonads were isolated and fixed to be prepared
until they were examined and photographed by the transmission
electron microscope. Examination of the ultrastructure of the
spermatozoa of the three species revealed that sperm of each of
them composed of head (acrosome and nucleus), Neck region,
midpiece and end-piece. The nucleus has nuclear fossa in which
impregnated the components of the neck region. The midpiece
contains the mitochondrial derivative and one glycogen helix
containing glycogen granules. The end-piece contains only the
axoneme surrounded by the plasma membrane. The axoneme has the
typical 9+2 microtubule arrangement. There are some differences
between them which can be summarized as follow; the nucleus in
M. obstructa has a perinuclear sheath, the plasma membrane is
convoluted in M. cantiana, the coarse fibers are present in the
neck region in the three species but in M. obstructa they extend
until the end of the midpiece. The midpiece can be
differentiated into glycogen helix region and mitochondrial
derivative region in M. cantiana and M. cartusiana but in M.
obstructa it can be divided into glycogen helix region, middle
region and posterior region. The mitochondrial derivative region
in M. cartusiana contains cortical microtubules. In M. obstructa
the anterior region of the midpiece has the glycogen helix; the
middle region has the glycogen granules in a tubular form around
the axoneme, while the posterior part contains only a
condensation of glycogen granules around the axoneme. The
glycogen helix region in M. obstructa contains cortical
microtubules beneath the plasma membrane. According to the above
descriptions of the ultrastructure of the spermatozoa of the
three species of Monacha in Egypt and due to the presence of
many differences between them, the present study recommend that
they are actually three valid species representing this genus of
land snails in Egypt.

Abstract:
Armenian people include one of the most important religious
minorities of Iran and they have been regarded as one of the
most professional and intellectual population of the country.
Since there have been few articles or books regarding the
educational system of Armenian-Iranian people up to now, this
article reviews the challenges and efforts of Armenian society
for establishing their own educational system in Iran from the
Mashrotiat (Constitutional) event to 1978 (the Islamic
revolution), mainly during the reign of Pahlavi. This research
was conducted based on the documents and studies performed
regarding Armenian educational policy in Iran.
The
results show that the principle of education and religious
training was regarded as a main challenge for the Supermen Armenian council in different provinces of Iran since 1941 and
Armenians tried to follow up their request in different methods
by referring to the ministry of culture and prime minister of
the country. Establishing Armenian schools in different
provinces of country was involved with different problems
influenced by the socio-cultural condition of the province
itself and the central government policy.

Abstract:
The present study was conducted to investigate the changes in
lipid and fatty acid composition of gamma irradiated rabbit meat
samples were aerobically packaged and exposed to gamma
irradiation at doses of 0 and 3 kGy at room temperature and 0
and 7 kGy at the frozen state. Lipids were extracted and
isolated as neutral lipids and phospholipids classes, then the
individual fractions of these classes were separated by thin
layer chromatography. Furthermore, the observed neutral lipids
and total phospholipids as well as the major phospholipids
fractions, phosphatidylcholine and phosphatidylethanolamine,
were converted to fatty acid methyl esters and analyzed by gas
chromatography. The obtained results revealed that irradiation
of rabbit meat samples had no significant effect on their
contents of total lipids and the observed fractions for neutral
and phospholipid classes were similar in lipids separated from
irradiated and non-irradiated rabbit meat. Moreover, irradiation
treatments showed no significant effects on the contents of
triglycerides, however, significant decreases in the contents of
cholesterol and phospholipids were observed. The fatty acids of
neutral lipid class showed no significant changes due to
irradiation of rabbit meat, while significant decreases, but of
minor interest, were observed in the polyunsaturated fatty acids
of total phospholipids and their major fractions. The observed
results demonstrate that irradiation of rabbit meat samples at
doses recommended for irradiation of poultry had no adverse
effects on their lipid and fatty acid composition and the
observed decreases in the contents of cholesterol or
phospholipids and their polyunsaturated fatty acids were of
minor interest.

Abstract: Fe, Zn, Cu, Pb
and Cd concentrations were determined in muscle, gills and liver
of fresh and salted (either by analytical or industrial salt)
mullet fish caught from El-Burullus Lake. Heavy metal
concentrations varied significantly depending on the type of the
tissue and salt. Generally, the lowest concentrations of the
studied metals were found in fresh fish, while the
highest concentrations were recorded in salted fish by
industrial salt which were higher than salted fish by analytical
one. Fish organs of fresh and salted fish by analytical salt
contain metals followed the order: liver>gills>muscle, while in
salted fish by industrial one showed: gills>muscle>liver. The
metal levels were ranked as follow: Fe>Zn>Cu>Pb>Cd. Fe and Cd
concentrations exceeded the upper limit of standards while, Zn
one recorded much below level in all deliberate fish organs. Cu
content was slightly higher than the permissible limit in muscle
and gills of salted fish by industrial salt. Concerning Pb
level, it was almost double the concentration of the permissible
limit in the liver of all groups and muscle of salted fish by
industrial salt, while it were triple the concentration of the
permissible limit in gills of that group.

Abstract:
Heat stress is one of the physical stresses which play a role in
arising central body temperature and making changes in immune
and hormone responses. The purpose of this study is to examine
the effect of one stage severe aerobic exercise in warm
environment on active women’s immune and hormone factors. 16
physical education students with average age of 20.25 ±0.9
years, maximal oxygen uptake of 42.14±9.8 ml/kg/m and body mass
index of 22.11±2.66 kg/mm have randomly divided in tow
experimental and control groups. The experimental group has
pedaled the ergometer wheels with VO2max 75% for 60
minutes and the control group has no activity during the test.
The environmental temperature and humidity were maintained 33°
centigrade and 40% respectively fixed during the test. Blood
samples for measuring the levels of IL-10, TNFα, CRP, cortisol,
epinephrine were taken in three periods pre, immediately and 2
hours after termination of the activity from participants. There
wasn’t any significant difference between control and
experimental groups in density of IL-10, TNFα, CRP, epinephrine
when they were doing intensive activity in warm weather. There
were only significant differences between groups on density of
CPR and immediately and two hours after activity (p≤0.05).
These data demonstrate that a 60 min exercise heavy in hot
environment under these conditions can not affect on immunity
and hormonic responses in activity women.

Elastic Joints
and its lateral forces
Futuristic
structural concept
Hesham Gerisha
Misr University for
Science and Technology – 6.October city –Egypt
Con_develope@hotmail.com
Abstract: Bridge structures have been supported on flexible and elastomeric
bearings for a number of years. In this paper supporting the
structure system concerning buildings in every connection on
elastomeric bearing will be discussed. The human body structure
content elastic joints in its connection. A simulation of this
concept can be useful for the buildings concerning earthquakes.
Most structures act
as transfer elements, receiving certain forces and transferring
them to other points. This transfer capability is dependent on
the internal strength and stability of the structure. A thin
sheet of aluminum may be easily buckled, a block of wood may be
easily split along its grain, and a rectangular framework with
loose, single-pin joints may be easily collapsed sideways. All
of these structures fail because of an inability to maintain
internal equilibrium through lack of strength, or because of the
lack of some inherent stability, or for both reasons. The complete static
equilibrium of a structure requires two separate balances: that
of the external forces and that of the internal forces.
Externally sufficient reaction components must be developed by
the supports. Internally, there must be an inherent capability
for stability and sufficient strength to do the work of
transferring the applied loads to supports. But what is about a
flexible structural system? Can we damage the movement of the
system? Are sensors useful for this new structural concept? The
idea is to develop a steel structure system with elastic
connection. And this system includes a error reader (sensor)
response for the linearity of the system. If we have any
horizontal force in form earthquakes or wind the sensor give the
signal to the stepper motor to correct the error through moving
the structure with the tension member. We propose that the
humane design is one of the most important principles of
sustainability in architecture.

Abstract:
Foot ulcers are a significant source of morbidity, mortality and
diminished quality of life (QOL) in patients with diabetes.
Hyperbaric oxygen therapy (HBOT) has been proposed as a possible
treatment. Aim: this study aims to evaluate the effect of HBOT
on QOL in patients with diabetic foot ulcers. Methods: A
quasi-experimental design was used. This study was conducted at
the HBOT unit and surgical outpatient clinics, affiliated to
Naser Institute Hospital. Sample: A purposive sample included 46
adult patients with diabetic foot ulcers. Tools: 1) Patient's
interviewing sheet to assess QOL domains: physical,
psychological, social and spiritual (pre/post tests), 2) Strauss
wound classification scoring system (Pre/post tests), 3) Wound
symptoms chart (pre/post tests), 4) Hamiltons anxiety rating
scale and 5) Numerical rating pain scale (pre/post tests).
Results: Statistically significant differences were found
between QOL domains before and after HBOT among the studied
patients. Moreover there is an obvious improvement regarding
wound ulcers healing added to significant reduction in the
anxiety level post treatment sessions. Conclusion: HBOT had a
positive effect on the improvement of QOL in patients with
diabetic foot ulcers, which is possibly attributable to better
ulcers healing. Recommendations: Further studies should be done
to assess the long term success of HBOT and to follow up
patient's QOL.

Abstract:
Clostridium botulinum [C. botulinum] is an
obligatory anaerobic, Gram positive, endospore forming
bacterium. It produces lethal botulinum neurotoxin (BoNT) that
causes life threatening neuroparalytic illness known as
botulism.
Many cases of foodborne and infant botulism were reported
worldwide.
This study determined the prevalence
of C. botulinum
and its spores
in some Egyptian food products using conventional methods and
Multiplex PCR.
A total
number of 250 food samples (50 honey, 100 fish products and 100
meat products) were randomly collected from apiaries, fish
shops, butcher shops, retail stores and supermarkets in Assiut
City. They were examined for the presence of C. botulinum
and its spores using conventional methods. Finally,
multiplex PCR
was done for genotyping isolated
C. botulinum
neurotoxin
genes types (A, B, E and F). Total number of positive samples
for C. botulinum was 13 (26 %) in honey, 19 (19%) in fish
products and 21 (21%) in meat products. Standard filtration (SF)
method detected C. botulinum spores in honey more
efficiently than Dilution centrifugation (DC) method. Genotyping
using multiplex PCR was successful. It revealed that C.
botulinum type A was 10% in honey and 6% in meat products;
C. botulinum type B was 20% in honey, 5% in fish and 11% in
meat products; C. botulinum type E was 14% in fish and 4%
in meat products. While, C. botulinum type F was 0%.
The present study revealed that
some
food products in Assiut City may present a potential hazard for
foodborne and infant botulism.

Computer-Aided
Design of Framed Reinforced Concrete Structures Subjected to
Flood Scouring
Hamed Salem
Structural
Engineering Dept., Cairo University, Giza, Egypt
hamedhadhoud@yahoo.com
Abstract:
In the beginning of 2010, several reinforced concrete structures
collapsed due to floods in Sinai and Aswan, Egypt. Scour of soil
beneath foundations lead to excessive differential settlements,
failure of main structural members and finally complete
structural collapse. A three-dimensional nonlinear dynamic
analysis of a multi-storey reinforced concrete framed structure
with induced soil scour under its foundation is carried out
using the Applied Element Method. The analysis of the structure
is followed until its complete collapse. The numerical analysis
is then used to propose a safe design against collapse. Three
different alternatives proposed for preventing progressive
collapse are independently investigated; floor beams, tie beams
connecting footings, and diagonal bracings. Increasing the size
of the floor beams was found not to have significant effect on
mitigating progressive collapse, while the use of diagonal
bracings in the ground floor or rigid tie beams connecting the
structure’ footings was found to efficiently prevent progressive
collapse. With diagonal bracings or rigid tie beams, the
excessive differential settlements of the footings can be
eliminated and the gravity loads can follow a safe alternative
path preventing the structural collapse. The tie beam
reinforcement was found to have a significant effect on the
structural behavior during such an extreme loading case. Section
analysis of the tie beam suggests that its ultimate strength
should be based on rupture of main reinforcement, which is more
economical and appropriate for such loading case.

Abstract:
The effect of different nitrogen levels (0, 200 and 400 kg urea
ha-1) and
phosphorus
rates of 0, 100, 200 and 300 kg ha-1 in the form of
triple superphosphate
on growth and yield components of sweet corn was investigated at
a research field, in Takestan, Iran, during 2006 growing season.
The experiment was carried out using split plots based on
randomized complete block design with four replications.
Results showed that nitrogen fertilizer effect was significant
on number of grains per ear, number of nodes per stalk, ear
height, ear diameter,
husked green ear
weight, 1000-grain weight, plant height and grain yield of sweet
corn. Phosphorus rates significantly affected plant height, ear
diameter, ear height, grain yield,
husked green ear
weight and 1000-grain weight. Interaction effect of nitrogen ×
phosphorus was only affected 1000-grain weight, grain yield and
husked green ear weight. whereas
the rest of studied traits were remained unaffected. The highest
grain yield (7781.10 kg ha-1) was that of application
of 200 kg urea ha-1 coupled with 200 kg ha-1
of triple superphosphate.
It is concluded that optimum dose of phosphorus/nitrogen for
sweet corn crop is 200 kg ha-1. It is also suggested
that further research should be done under different
environmental conditions.

Abstract:
Pharyngeal
carcinoma has been identified as a significant public health
threat. Systematic evaluation of the significant impact of
several prognostic factors in pharyngeal carcinoma
treated either with radiotherapy alone or in
combination with chemotherapy is of great importance to health
care providers and policy makers. This study used to evaluate
the correlations between disease characteristics, treatment, and
survival for patients with pharyngeal carcinoma. Main outcome
measures were disease-free survival, overall survival,
and treatment response. Methods: This study included 97 patients with pharyngeal carcinoma treated at
Clinical Oncology Department, Faculty of Medicine, Tanta
University Hospital between January 2000 and December 2005.
Results:
The mean age of all patients was 50.18 years (range; 23 - 75
years). Men made up 61.9% of patients. Pathologic
diagnosis was squamous cell carcinoma (SCC) in 77.3% of cases.
Younger patients (<50 years) had a much higher frequency of
presentation with stage I and II tumors (58.5%). Most tumors
were located at the hypopharynx (57.7%) with clinical
stage III or IV (63.9%). Treatment response was
associated with age, tumor status, nodal status, tumor site,
Karnofsky performance status, and clinical stage before
treatment. The 2-year overall survival (OS) rate for
all patients (n = 97) was 21.6% and the 2-year
disease-free survival (DFS) rate for patients who achieved
complete response (n = 31) was 51%. The significant
prognostic variables were Karnofsky performance status, nodal
status and primary tumor volume.
Conclusion: A
combination of clinical factors, such as primary tumor volume
measurement, nodal status, tumor site, Karnofsky performance
status, age, and clinical stage are reliable ways to stratify
outcome as predictors of overall survival,
disease-free survival, and treatment response in pharyngeal
carcinoma.

Abstract:
The size composition,
growth pattern, sex ratio and gonadal stages of Callinectes
amnicola (De Rocheburne) in three interconnecting tropical
lagoons were investigated over 18 months. The major ecological
variable in the lagoons was salinity. The crabs exhibited
negative allometric growth. The largest sized crabs were
obtained in the freshwater Lekki Lagoon. The males were
significantly more abundant than the females in the freshwater
Lekki Lagoon while the sex ratio was nearly 1:1 in the brackish
Badagry and Lagos Lagoons. Five stages of gonadal maturity were
recorded for both males and females in the three lagoons. Fecund
females carrying eggs underside of the abdomen were obtained
only in the high brackish water Lagos Lagoon. The salinity
gradient and occurrence of the blue crab throughout the year in
the three interconnecting lagoons makes them a suitable
environment for completion of its life history in the lagoons.

sorption time, initial metal ion concentration and adsorbent
dosage were evaluated. The results showed that these parts of
dump palm have relatively high adsorption capacity for these
heavy metals ions. The percentage removed was (76%), (64%),
(62%) and (64%) (57%) (56%) for Mn (II), Cu (II) and Zn (II)
ions respectively for frond and leaves. Adsorption equilibrium
was established in 90mins for Mn (II), Cu (II) and Zn (II) ions.
The equilibrium data generated fitted well for Freundlich
adsorption model. The obtained results show that the both the
leaves and the frond of dump palm are favourable for the
sorption of the heavy metal ions.

Abstract:
In this study, the effects of
micro and nano silica particle size and their quantity on
mechanical properties and microstructure of fabricated cement
mortar was investigated. The measurements carried out at the 7th
day after the production of the cement mortar. The results
showed that the cement mortar containing silica nanoparticles
had better mechanical properties compared with the pure cement
mortar. The production method used here caused a homogenous
dispersion of silica nanoparticles in the cement mortar;
therefore, its mechanical properties increased even with
addition of only 1% silica nanoparticles. In the othr words the
compressive strength increased by more than 100% by addition of
critical amount of SiO2 nanopowder. The SEM, DTA,
TGA, water permeability tests revealed that nano and
microparticles not only work as fillers for the cement mortar’s
porosity and improves its microstructure, but also reduce the
amounts of Ca(OH)2 and other calcium hydrates.

Abstract:
Background and Aim of the Work: Brain tumors are the most common
solid tumor in children and are the second most common neoplasm
in childhood after hematological malignancies, and accounts for
20% of all pediatric cancers. Approximately half of all
intracranial neoplasms in children are found within the
posterior fossa. Conventional magnetic resonance imaging is the
corner stone in the initial evaluation of pediatric brain
tumors. The purpose of this study was to assess the role of MRI
in differential diagnosis of infratentorial brain tumors in
children by MRI. Patients and Methods: This study was carried
out on 30 patients (17 male, 57% and 13 female, 43%), their age
ranged from 4 – 11 years old with the mean age 7.5 years. All
patients were selected according to their presentation with
cranially related manifestations and all were subjected to full
history, full clinical data and radiological examination by MRI.
Results: The MRI evaluation and histopathological reports showed
that: 10 cases of cerebellar juvenile pilocytic astrocytoma
(33%), 10 cases of medulloblastoma (33%), 4 cases of infr
atentorial ependymoma (13%), 5 cases of brain stem glioma (17%)
and one case of atypical teratoid rhabdoid tumor (3%).
Conclusion: Magnetic resonance imaging (MRI) is the primary
imaging modality used for the assessment of intracranial tumors
as MRI provides superior delineation of the extent of tumor.

Abstract: Backtiari area is
located in south west of Iran in alignment with Zagros Mountain, Covering 39900 Km, including towns such as Daran and Fereidan
shahr (Isfahan Province), Aligodarz (Lorestan District),
Dezfool, Andimeshk, Masjed soleiman, Izeh, Shoshtar (Khuzestan
Province), Borojen, Lordegan, Farsan (Charmahal Backtiary
Provincel).
Ize is a small town with 3930km
located in north east of Khuzestan province between eastern
latitude (T) and northern altitude This town is, 200 KM to Ahvaz
the capital of khozestan province.
Among the population
residing in this town, 108232 people are living in urban
districts and the rest are the rural communication living at the
countryside. This town is cold in autumn and winter and warm in
spring and summer.
Although Izeh is a part of
Backtiarian area, but there are some important difference
between the language common in Izeh area and other Backtiarian
population. Many books and articles have been published
regarding the history, culture and linguistic characteristics of
the whole Backtiarian population. Among them we may refer to (1)
conversation customs and beliefs of Backtiarian People (Adivi),
(2) Backtiarian Language which is dominantly as a dictionary
instead of paying attention to languages (Khosravi) (3)
Backtiari language dictionary written by saral (2002) (4)
summary of Backtiarian poems (Mir Ghayed) – 2003), (5),
Backtarian legend (Daghighian), (6) poems (Divan) of Mulla
Zolfali Backtiari (Backtiari – 1996) and a book a bout the
history and geography of Ize which is part of the Islamic
Encyclopedia including also some common words and language in Backtiari which is different from Izeh Language. Since a
significant part of Iranian population in khozestan, Isfahan,
Fars and Lorestan provinces talk in this language, this article
is intending to focus on
Historical transformation of vowel sounds from traditional P
persian to current Bakhtiarian Izeh language.
On the other hand,
oil discovery in this area
increased its importance for many geographic, sociologic
researchers and historians, among them Scarmann was first
foreigner who published some texts of Backtiary literature in
1904 and a Russian researcher, called Dimitry Jokovski published
some of these texts in Saint Petersburg in 1923. In 1922,
Lorimer and English officials working in Iran worked on some
language in Iran as well as Backtiary language and published
some of them in BSOAS Izeh area. Through the history of
Backtiary population played a significant role in Iranian social
political situation, and this society was under the attention of
many tourists and researchers.

Abstract:
The finite element is introduced to describe the behavior of
circular columns: confined, partially confined or reinforced
with fiber reinforced polymers (FRP). Geometric and material
nonlinearities are taken into consideration. The column is
analyzed under axial force together with a biaxial moment
applied at its ends. This paper presents the initial results of
a study aimed at quantifying the increase in strength of columns
due to introducing FRP in different methods. Results show that
using FRP as external wrapping gives higher increase in
strength than using it as embedded reinforcement.

Abstract:
The potato tuber moth
Phthorimaea operculella Zeller
(Lepidoptera - Gelechiidae), is a major pest of the
potatoes world-wide attacking the foliage and infest the tubers
in both field and store causing serious economic damage. In this
study, the efficacies of seven insecticides [organophosphate (Fenitrothion
& Pirimiphos-methyl), carbamate (Carbosulfan & Aldicarb),
pyrethroid (Lambda-cyhalothrin & Deltamethrin) and imidaclopride
(Confidor)] were determined against four strains of P.
operculella collected from four
Governorates in Egypt [Damytta (DAM), Dakahlia (DAK), Behera (BEH)
and Menofia (MEN)]. Collected strains were bioassayed and
compared with a reference susceptible strain. DAM and BEH
strains recorded 193.4 and 23.3-fold resistance, respectively to
fenitrothion and also recorded 133.7 and 23.6-fold resistance,
respectively to pirimiphos-methyl. DAM and MEN strains recorded
87.2 and 23.8-fold resistance, respectively to lambda-cyhalothrin
while DAM and BEH strains recorded 81.2 and 13.7-fold
resistance, respectively to deltamethrin.
DAM and MEN strains demonstrating 36.1
and 16.6-fold resistance, respectively to carbosulfan while DAM
and BEH strains demonstrated 63.4 and 7.1-fold resistance,
respectively to aldicarb, and also DAM and BEH strains recorded
134.7 and 15.3-fold resistance, respectively to confidor.
These results are discussed in relation to the possible
mechanisms of resistance present in the studied P.
operculella strains and
underpin the resistance management strategy for
potato tuber moth
in Egypt.

Abstract:
The significance of budget and
current account deficits dates back to 1980s which trade and
budget deficits dramatically increased in the United States. Two
theories have been arisen about twin deficits: Keynesian theory
and Ricardian equivalence. According to Keynes theory, the
budget deficit affects the domestic and foreign economy, while
the Ricardian equivalence neglates any relationship between
budget deficit and other economic sectors including domestic or
foreign. In this paper, two visions are theoretically studied
and eventually the impact of budget deficit over the variables
of domestic sector (private consumption and economic growth) and
variable of foreign sector (current account deficit) within the
period of (1985-2006) will be analyzed. The review of this
issue has been conducted for different countries (70 countries)
which according to the world development indicators are
categorized into 3 groups of high, middle and low- income
countries. A summary of the acquired results would not affirm
the relationship between the budget deficit and current account
deficit, consumption and economic growth in the period of study
in high-income countries. This relationship remains in force in
middle and low income countries, in other words Ricardian
equivalence is rejected in these countries.

Abstract:
Two experiments
carried out to determine the effects of rumen protein
availability on ewe's performance at transition period. The
first trial were performed using the in sacco method with
two fistulated Zel ewes to determine degradability of untreated
(UCM) and formaldehyde treated canola meal (FTCM; 4 ml/ 100 g
CM). In second experiment,
sixteen
3-years old pregnant Zel ewes (133 ± 4day in pregnancy) were fed
ad libitum two rations that consisted of UCM and FTCM with same
composition that offered as a TMR twice daily at 0900 and 2100
h. Formaldehyde treatment decreased a, b, potential degradable
fractions and effective degradability for dry matter (DM) and
crud protein (CP), with no effect on neutral detergent fiber
(NDF) degradation. The FTCM increased body weight before lambing
and reduced body weight loss after parturition. There were no
differences between DM intake (except on 2 weeks after lambing).
Control treatment had greater digestibility for CP, NDF and ash
than FTCM treatment. The body weight of lamb at birth, 7, 14 and
21 day after lambing and lamb’s daily gain were higher in
treatment than control. Milk production, fat (% and kg/day),
protein (kg/day) and total solid (%) content of milk increased
in sheep that fed ration contained the FTCM. However, using FTCM
enhanced milk production (13.2 % based on control), therefore,
can be beneficial to high-producing dairy ewes.

Abstract:
Social networks not only help to
increase social captials but also expand the communications
between people. This is important because we can see erosion of
social captials in today world. Developing communication and
information technologies provides people to have a virtual
social network in a cyber space through their interactions and
enjoy its supports. So, this study has tried to analyze the
conditions of required social supports from Online Interaction
Network in Tehran users in 2010-2011 through Online
Questionnaire and ground theory.
This study shows that
Tehran On-line interactions users in their virtual social
network in on-line interactions do not receive many supports
from the network. It means that: 1) each person in his own
network does not need or expect to receive some kinds of aid 2)
companionship and advice is two main aids in this network. Since
the social network of the person in real world is his main
network and his support source, it seems that social network
provides some kinds of supports which the person isn’t able to
ask for or provide them in the real world. The most required
support in Chat On-line interaction users is companionship.
Undoubtedly, the received supports from virtual social network
help people to compensate some support gaps in real world as
well as expanding the communication.

concluded that, more than half of the patients in study group
53.3 % were females, 70 % were married, and 40 % their ages
ranged from 18 - 29 years. While the majority of the patients in
the control group 63.3 % were male, 46.7 % were married, and
33.3 % from 30 - 39 years. Conclusion; Significant differences
for improvements throughout educational program phases among
study group regarding total score of knowledge and practice
about open heart surgery. The study recommended that, pamphlets
and simple illustration booklet should be available for patients
illiterate to with simple explain how to safely live after open
heart surgery. The patients must understand the importance of
oral hygiene and visiting a dentist regularly because dental
infections can affect the valve prosthetic.

Ventricular Dysfunction Induced Weaning Failure? Invasive &
Echocardiographic Evaluation
Akram
Abdelbary; Yasser Nassar; Khaled Hussein & W Ayoub
Faculty of medicine, Cairo
University, critical care department
Abstract:
Introduction:
Cardiovascular dysfunction may
contribute to unsuccessful ventilator discontinuation & promote
prolonged ventilator dependence.
Aim:
Studying the relation of weaning failure to development of LV
diastolic dysfunction using echo & PA catheter
Methods:
Thirty invasively mechanically
ventilated patients fulfilling criteria of weaning from
mechanical ventilation & Shifted to SBT (using low PSV (8
cmH2O)) for 30 minutes. 2 sets of variables were measured at the
beginning& end of the SBT; Weaning failure was defined as;
Failed SBT, Reintubation and /or ventilation or death within 48
h. Following extubation, Swan Ganz catheter was inserted to get
the right atrial (RAP), pulmonary artery (PAP), pulmonary artery
occlusion (PAOP) pressures, & cardiac index (CI). Using
trans-thoracic Echocardiography; The LV internal diameter at end
diastole (LVIDd) & end systole (LVIDs), Ejection fraction (LVEF
%), E/A ratio; Deceleration time (DT), Isovolumetric relaxation
time (IVRT) in ms were measured & E/E` ratio using tissue
Doppler imaging (TDI). Results:
Mean age was 56.6
±15.9 years, 53% were males. The outcome of weaning was
successful in 76.6% of patients. The pts were subdivided into
two groups according to weaning outcome; Group І: 23 pts
(successful weaning), Group ІІ: 7 patients (failed weaning).
RAP,PAOP&SVO2 were similar at the start of SBT(6.3±1.9
vs.7.6±2.3, p=0.1), (12±3.7 vs.14.6±3,p=0.4),(72±2.4
vs.71±3.1, p=0.1) between group І & ІІ yet significantly
different at the end of SPT; (6.2±2.4 vs.10±3.5,p=0.01),
(12.8±3.5 vs.19±5.4, p=0.004), (73±2.8 vs.66.6±7, p=0.009)
respectively. CI was similar between group I &II at both ends of
the SBT, p=0.5&0.9.Group I & II had similar LVIDs & EF at the
beginning of SBT (3±0.7 vs. 3.3±0.5,p=0.2),(68±8vs.62±6,p=0.08)
yet different at the end (3±0.6 vs. 3.5±0.5,p=0.048),
(66±8vs.58±7, p=0.03) respectively. There was no significant
differences in E/A,IVRT,DT yet significant difference in E/E'
between group І & group ІІ at both ends of the trial; (1.04±0.4
vs. 0.97±0.3,p=0.78),(1.02±0.4 vs.1.07±0.4,p=0.78),(94±26 vs.
99.6±18, p=0.52), (97±22vs. 91±24,p=0.57), (194±31 vs.
196±30,p=0.98),(197±27 vs.189±33, p=0.6), (8.9±2 vs. 12.2±4,
p=0.02), (9.4±2.3 vs. 13±5, p=0.02) respectively.
Conclusions:
LV dysfunction may have an
impact on weaning outcome. Invasive monitoring as well as
echocardiography and tissue Doppler indices may be reliable in
monitoring and detection of LV dysfunction and subsequently may
be possibly useful in improving weaning outcome
RAP may be particularly a
reliable and easy method to monitor during the period of
weaning.

Abstract: The High
Impedance Faults (HIFs) are the faults which are difficult to
detect by overcurrent protection relays. In this paper a general
logic-based intelligent approach for detecting and classifying
the HIF in distribution systems is presented. The proposed
approach recognizes the distortion of the current waveforms
caused by the arc usually associated with HIF. The Discrete
Wavelet Transform (DWT) based pattern recognition is used for
extracting the current signals. Single line to ground, double
line to ground, and three lines to ground faults are classified
using three simple logic functions. In order to detect the
faulty feeder a general logic-based intelligent approach has
been designed. The proposed approach is verified by applying
several fault scenarios on IEEE-34 node test system. The
proposed approach can be applied for any configuration, current
rating or voltage rating. The results confirm that the proposed
approach accurately detects and classifies the HIF in the
distribution systems.

Investigation of Ferroresonance in Offshore Wind Farms
Ebrahim A. Badran,
Member, IEEE,
Mohammad E. M. Rizk, and Mansour H. Abdel-Rahman,
Member, IEEE
Egypt
Abstract —
Up to date, many literatures have investigated ferroresonance in
electrical systems particularly distribution systems due to
abnormal switching operations. Ferroresonance has bad effects on
the insulation system and causes damages to surge arresters
also. Recently, many researchers have investigated
electromagnetic transients in offshore wind farms after the wide
penetration of offshore wind farms in many countries as a
renewable source of electricity. However, ferroresonance
phenomenon has not been investigated in offshore wind farms.
This paper investigates ferroresonance phenomenon and its bad
effects in offshore wind farms. The PSCAD/EMTDC program is used
for modeling the offshore wind farm. The offshore wind farm
investigated in this study consists of 72 wind turbines arranged
in eight rows. Ferroresonance in offshore wind farm in this
investigation is produced by three different abnormal switching
operations.
The results show that the transient overvoltages produced by
ferroresonance have bad effects on the insulation of both
submarine single-core cables and the transformers. The results
show also the surge arrester damage due to the continuity of
ferroresonance phenomena. Furthermore, this paper suggests a
protective method for suppression the ferroresonance in offshore
wind farms. The results show that the proposed protective
method against ferroresonance gives high suppression to
ferroresonance in offshore wind farms.

A
Comparative Study between intralesional Low Molecular Weight
Chitosan and Triamcinolone Acetonide for Treatment of
Erosive-Atrophic Oral Lichen Planus.
Egypt
Abstract:
BACKGROUND:
Oral lichen planus (OLP) is a common chronic inflammatory
mucosal disease in which T-cell mediated immune responses are
implicated in the pathogenesis. Various treatments have been
employed to treat symptomatic OLP, but a complete cure is very
difficult to achieve because of its recalcitrant nature. Topical
corticosteroids therapy of OLP has shown conflicting results in
many reports. The purpose of this study was to compare the
effectiveness of topical intralesional 1% low molecular weight
chitosan with topical intralesional Triamcinolone Acetonide in
the treatment of oral erosive and atrophic lichen planus and
level of TNF-α.
METHODS:
Twenty patients with symptomatic OLP were randomly assigned
treatment with intralesional 1% low molecular weight chitosan or
Triamcinolone Acetonide. The assessments were at weeks 0, 2, 4,
16 by appearance score, pain score, and TNF-α of the target
lesions. Results: Appearance score, pain score, and
TNF-α, were reduced in both groups. No significant differences
were found between the treatment groups regarding the response
rate and relapse. Conclusion: Our study demonstrated that
1% low molecular weight chitosan was as effective as topical
triamcinolone acetonide therapy without any adverse effects and
it may be considered as an alternative treatment for
erosive-atrophic OLP in the future.

Abstract:
Over the last three decades, cisplatin has been one of the most
effective cytotoxic agents, but its administration has been
hindered by its nephrotoxicity, neurotoxicity, myelotoxicity,
and retinal toxicity. Recently, liposomal cisplatin has been
formulated and tested thoroughly in preclinical studies (in
vitro). Experiments on animals showed that liposomal cisplatin
is less toxic than cisplatin while keeping its anti tumor
function.Antioxidants are intimately involved in the prevention
of cellular damage by means of reducing the adverse effects of
reactive oxygen and reactive nitrogen species on the biochemical
processes in the body, hence, they play an important role in the
protection and defense mechanisms of the body. This study aims
to reduce the adverse effects of cisplatin on the blood and the
electroretinogram (ERG) of rabbits through the administration of
liposomal cisplatin and by liposomal cisplatin combined with
Ginkgo bilboa(G.b). To achieve this goal, 36 albino rabbits
were used and were divided into 6 groups, the first group didn't
receive any treatment (control group), the second was given
Ginkgo biloba only, the third one was administrated with IP
cisplatin only, and the fourth was given oral Ginkgo biloba plus
IP cisplatin. The fifth and sixth groups were administrated with
liposomal cisplatin and liposomal cisplatin plus Ginkgo biloba
respectively. Our results indicate that there was a reduction of
some hematological parameters and ERG waves after the
administration of cisplatin, while these values reached
comparable values to the control level in the fifth and sixth
groups.

Abstract:
Introduction:
Post operative pain is an expected adverse outcome following
surgery and it often delays mobilization and overall recovery.
Acute post operative pain is subjective and cannot be measured
directly. Aims: The aim of this study was to: 1- Assess
nurses' postoperative pain assessment and management
documentation of pain in the first three days postoperatively in
the surgical wards at Mansoura University Hospitals. 2-Assess
nurses’ knowledge of and attitudes toward pain in the surgical
wards at Mansoura University Hospitals.3- Assess nurses’
communication with patients and their satisfaction of pain
management, and 4-Evaluate the effectiveness of implementing a
postoperative pain assessment and management program (POPAM) on
improving nurses’ documentation, knowledge, attitudes,
communication with the patients and their satisfaction of pain
management. Subjects and Method: The POPAM program was
implemented for six months during the period of Data were
collected by interviewing 18 nurses working in surgical wards at
Mansoura University Hospitals. The program was evaluated by
means of a quasi-experimental pre-post test design Documentation
of pain in the first three days postoperatively in the patients'
records were audited, nurses’ knowledge of and their attitudes
toward pain, and, assessment of nurses’ communication about pain
with patients and their satisfaction about nurses’ intervention
were assessed before and after implementing the program.

Abstract:
Along with the evolution in the
scope of nursing practice, there has been greater autonomy for
nurses and a growing demand for expanded critical thinking
abilities. Therefore, Critical thinking in nursing is an
essential component of professional accountability and quality
of nursing performance. So, this study aimed to examine the
relationship between the disposition of staff nurses toward
critical thinking and quality of their performance at Mansoura
University Hospital. Cross sectional descriptive design was used
for staff nurses working at all general medical and surgical
units of Mansoura University Hospital. It included 95 staff
nurses (35 staff nurses working at medical units and 60 staff
nurses at surgical units). Data collected through two tools: the
first tool consists of two parts; the first part was intended to
collect demographic characteristics; and the second part was The
California Critical Thinking Disposition Inventory. The second
tool was Observation checklist to measure staff nurses '
performance. Within the total sample (n=95) the relationship
between the disposition of staff nurses toward critical thinking
and quality of their performance was statistically
significant.

Nursing Guidelines For Improving Foot Care Practecies For Adult
Patients With Type 2 Diabetes
Based on National Institute for Clinical Excellence guidelines,
2004.

Abstract: Foot problems are a common complication in people with diabetes.
Fortunately, most of these complications can be prevented with
careful foot care. If complications occur, daily attention will
ensure before they become serious.
These complications have been shown to be already present in
about 10% of diabetic patients at the time of diagnosis.
Teaching patients proper foot care is a nursing intervention
that can prevent costly, painful, and debilitating
complications.
Half of all major leg amputations in the UK are performed on
people with diabetes who have uncontrolled ulceration,
infection, and gangrene. Morbidity and mortality associated with
the diabetic foot are unacceptably high, there is a perceived
need for evidence-based guidelines to improve outcomes in
management of the diabetic foot, which is a major public health
problem, In response to this, the National Institute for
Clinical Excellence (NICE) has published Clinical Guidelines in
Prevention and Management of Foot Problems (2004) for Type 2
Diabetes.
This study aims to improve foot care practice for adults with
type 2 diabetes mellitus. A quasi-experimental
intervention was conducted in Eldemerdash outpatient clinic for
diabetes, Ain Shams University Hospital, Cairo, Egypt, on a
sample of 180 type 2 diabetic patients randomly divided into two
equal study and control groups. Data were collected using
interview questionnaire, foot care practice scores; foot care
guideline was developed based on NICE Guidelines and implemented
on the study group. Data were collected at pre-post, and 3
months follow up phases. The finding of this study revealed that
the mean age of the study and control group was
39.3±5.6 and 40.3±4.9
years
respectively. About (19.8%) of
patients in the study and control (20.5%) groups had previous
exposure to foot injury, health information needs were very high
in both groups. At post and follow up tests, patients in the
study group had satisfactory knowledge, 95.3% and 87.2%
respectively (p<0.001), compared to 24.4% and 23.2% respectively
in the control group, in the study group adequate practice were
96.5% and 79.1% at the post and follow up phases among patients
in the study group, compared to 16.8% and 13.2% respectively in
the control group (p<0.001), It was concluded that foot care
knowledge and practice for diabetic adults were improved after
guidelines.

Abstract:
Atopic dermatitis (AD) is a chronic inflammatory skin disease
with 2 phases, acute and chronic.. Recent studies had shown
that inducible nitric oxide synthetase (i NOS) is expressed in
the atopic skin lesion, suggesting the involvement of nitric
oxide (NO) in the skin inflammation of AD. Soluble E-selectin
(sE-selectin)
adhesion
molecules expressed on endothelial cells can regulate leukocyte
migration and shed into the circulation. Their level in the
serum is known to reflect the degree of systemic inflammation,
and therefore be used as a marker of inflammations
and activity. Therefore, the aim of this study was to evaluate
the role of serum nitrate and sE-selectin concentrations in
relation to severity and clinical course of atopic dermatitis in
children. Serum Nitrate and sE-selectin levels were assessed in
40 patients with AD (24 males and 16 females) aged 8-84 months
and 16 healthy children as controls (9 boys and 7 girls) aged
6-60 months by ELIZA. Serum nitrate and sE-selectin
concentrations in patients with AD were significantly increased
as compared to non-atopic controls (P<0.001) and there were also
significant differences between subgroups of AD (mild, moderate
and severe) as compared to controls and among subgroups
themselves. The levels of both markers were significantly
diminished after treatment of severe cases of AD. Significant
correlations were present between serum nitrate levels,
sE-selectin levels, disease activity and eosinophilic count, but
no correlation was found between serum nitrate and sE-selectin
levels. Our results indicate that NO and Soluble
E-selectin may be involved in the pathogenesis
of AD skin and could be used as indicators of disease
severity and activity

Abstract:
Background;
CD40-ligand (CD154) is expressed on activated CD4+ T lymphocytes
and is essential for the T cell–dependent activation of B
lymphocytes. CD154 is also expressed at the activated platelet
surface.
Objective; to investigate the
role of CD154 in ITP pediatric patients and correlate their
levels with the course and progression of the disease. Subjects
and Methods; This study included 25 patients with acute ITP (13
Females and 12 males) with age ranged between 2-6 years
(group1).and 25 patients with chronic ITP (14 Females and 11
Males) with age ranged between 8 – 12 years (group II) also 25
apparently healthy children, (10 Females and 15 Males) with age
ranged between 3-12years as control (group III). Studied groups
were subjected to the following investigations; complete blood
counts, bone marrow examination and flowcytometric analysis of
CD154 B lymphocyte counts
Results; We found that
there was a highly significant increase in CD154in patients with
acute ITP compared with chronic ITP and control group p0.001 and
0.0001 respectively) also there was a negative correlation
between CD154 and platelet count in acute and chronic groups
(r=-0.6, p=0.004 and r=-0.5, p=0.005 respectively) Also there
was a positive correlation between CD154 and lymphocytic count
in acute and chronic groups (r=0.422, p=0.007 and r=0.77,
p=0.001 respectively),
Conclusion; the
increased number of CD154 might be one of the mechanisms that
cause immune regulation dysfunction in ITP also the count is
related to the severity of the disease as it was highly
increased in acute phase than chronic and therefore CD154
expression is increased in ITP and is able to drive the
activation of auto reactive B lymphocytes in this disease.

Abstract:
The colored areas under graph are used to evaluate the behavior
of the Egyptian genotypes under different locations and
comparing its results with classic statistical method. The
Egyptian cotton cultivars, namely, Giza 80, Giza 90 and the H6
genotype [G83x(G75x5844)] were grown at four different
locations at upper Egypt, namely; El-fayoum, El-menia, Sohag,
and El-matana. While, the Egyptian cotton cultivars, namely,
Giza 88, Giza 92 and H10 genotype [G84x (G70xG51b)x pima62] were
grown at four different locations at delta, namely; El -dkahlia, kafr El-sheikh, el-Behira and Damietta. The Experimental
design was a randomized complete block design with four
replications. The Upper Egypt genotypes gave their best fiber
quality under Loc 4 except for, the H6 genotype gave the best
fiber quality under Loc 3. However, all the genotypes couldn't
adapted to the weather conditions of the first locations. In
contrast, the first location exhibited the highest fiber
properties for Giza 88 and Giza 92 cultivars while the second
location exhibited the highest fiber properties for H10
genotype. The color area under radar graph indicated those results as
clear as compared with the statistical analysis.

abyat1389@gmail.com
Abstract:
The most powerful wave of
expansion of Islam in Indian subcontinent is indebted to the
migration of scholars, mystics, and Jurists to India. Scholars
believe that the contribution of Sufis in preaching Islam in
India was both positive and enormous. They developed close
contacts with the local people socially and culturally and
preached Islam amongst them. Four Sufi orders i.e. Chishtiyeh,
Sohravardiyeh, Qaderiyeh and Naqshbandiyeh have been popular in
India from early days till our times and are known more than
other orders in India. The Sufis of the subcontinent are in some
way or the other connected with these four schools of Sufi
order. The shrines and tombs of prominent Sufis of all these
orders are situated in Indian subcontinent and are centers of
congregation during annual URS i.e. the date of death of the
master Sufi. One of followers of Chishtiyeh is Mir Seyed Ashraf
Jahangir Simnani from Simnan city of Iran. He left Iran for his
destined goal in 8 century. After the long distance and passing
through different cities of India, he reached to Sheikh Ala
al-Haq in India.Then he went to small town called Kichowcha and
their expansion of Islam and mysticism there. This article is
about Seyed Ashraf Simnani’s life and his influence among Indian
and unknown small town called Kichowcha near Ahmedabad and
Lacknow.

Abstract:
The importance
of social capital and its variables including participatory
actions and voluntarily behaviors can be considered for higher
age ranges and elderly. Using randomized stratified sampling,
194 elderly in Ahwäz participated in the study. They were
randomly assigned to groups of experiment and control groups. It
was demonstrated that the two conceptual fields of
participation; interaction structures (networks) and the quality
of relationships (norms) have significant statistical
correlation with voluntarily actions of the elderly in the
experiment group. The findings were along with that of other
research in the elderly study field decreased social
participation, and reduction in elements of social capital is
associated with literacy and social awareness. Nevertheless,
investment in establishment and development of anticipatory
variables of social capital for the elderly will surely affect
their attitude toward an effective end for their individual
social life.

Performance
Status and the Number of the Metastatic Sites are Powerful
Prognostic Factors in Patients with Carcinomas of Unknown
Primary Site

Abstract: Previous studies dealing with prognostic features in patients with
carcinomas of unknown primary site (CUP) identified a number of
independent adverse variables such as male sex, a poor
performance status, a high number of metastatic sites, the
presence of liver metastases, and an elevated serum alkaline
phosphatase level. Because conclusions drawn from small series
are limited, many authors have advocated for the design of
randomized trials in CUP patients. Methods: Univariate and
multivariate prognostic factor analyses were conducted in a
population of 84 consecutive patients with CUP who were
evaluated at Oncology Department, Tanta University Hospital from
January 2006 to March 2010. Results: Univariate prognostic
factor analysis revealed baseline performance status (PS) of two
or more, >1 metastatic sites, poorly or undifferentiated adenocarcinoma, lung metastasis, liver metastasis, brain
metastasis and low serum albumin levels as adverse clinical and
biologic prognostic factors. Multivariate Cox regression
analyses showed that, poor PS and >1 metastatic sites had the
most powerful adverse impact on survival. We developed a
prognostic model using those two variables; a good-risk group
(PS 0–1 with 1 metastatic site) and a poor-risk group (PS ≥2
and/or >1 metastatic sites). The poor-risk group showed
significantly poorer overall survival (OS) than the good-risk
group (1 year OS 5.08% versus 40% respectively, P < 0.0001).
Conclusions: Cancers of unknown primary site has a poor
prognosis. Poor PS and >1 metastatic sites were identified as
adverse prognostic factors in CUP. Consideration of the authors’
to improve the prognostic model for survival of patients with
CUP is warranted.

Abstract:
Objectives: To
compare serum soluble endoglin (sEng) in women developed
pre-eclampsia (PE group) versus those free of hypertensive
manifestations (Control group) till delivery and to evaluate
the predictability of single estimation versus sequential
estimations for the development of PE.
Patients
& Methods: The study included all primipara attending the
antenatal care unit prior to the 12th week
gestational age (GA) so as to select 90 pregnant PE women.
Then, all women attended the clinic 4-weekly till delivery
for follow-up and to donate blood sample for serum sEng
estimation. Women developed PE
were
categorized according to time of development of PE into
Early- and Late-onset PE and stopped blood donation once
diagnosed.
Results: Thirty-eight women developed early and 52 women developed
late-onset PE. Mean serum sEng estimated at 16th
week GA were significantly higher in early compared to
late-onset PE, despite the non-significant difference at 12th
week GA and so the difference between 16th and 12th
week estimations was significantly higher with early versus
late-onset PE. Serum sEng estimated at time of PE diagnosis
was significantly higher in early compared to late-onset PE.
Serum sEng levels estimated at 12th week GA
showed positive significant correlation with the possibility
of development of PE and systolic blood pressure and at
cutoff point of 14 ng/ml could identify women liable to
develop PE with high sensitivity, but was a weak point for
differentiation between early and late PE, while on 16th
week GA at cutoff point of 6 ng/ml could specifically
identify women liable to develop early-onset PE
Conclusion:
Serum sEng at 12th week GA could be used as a
sensitive screening test for women liable to development of
PE and 4-weeks sequential estimation of serum sEng in
susceptible women could specifically identify women liable
to develop early-onset PE prior to clinical diagnosis.

Abstract:
Objectives: To evaluate the toxic effects of prenatal flutamide
exposure on testicular structure and ultrastructure of pubertal
rats. Materials
and Methods: 40 newly born male albino rats were divided into:
Control group: included 10 offspring whose mothers were injected
subcutaneously by vehicle only from the 10th
gestational day until birth and Study group: included 20
offspring whose mothers were injected by flutamide in a dose of
5 mg /day dissolved in vehicle from the 10th
gestational day until birth. When rats reached the adult age,
they were sacrificed and both testicles were removed and
prepared for light microscopic (LM) and electron microscopic (EM)
examination. Results:
LM examination of treated animals' specimens showed seminiferous
tubules containing few numbers of germ cells, spermatogonia and
spermatocytes with degenerated material in the cavity, but
contains no sperms. Part of the seminiferous tubule contained
edematous fluid in between the germ cells and the lumen of the
tubule contains debris of degenerated cells. EM examination
showed little number of degenerated primary spermatocytes and
Sertoli cells with multiple vacuoles in their cytoplasm, but no
sperms were detected in lumen. Higher magnifications showed
degenerated Sertoli cells with multiple vacuoles in its
cytoplasm and degenerated spermatogonia. In other parts of the
seminiferous tubules, Sertoli cells appeared deeply infolded (lobulated
nucleus) with vacuolated cytoplasm. Degenerated spermatogonia
with rounded nuclei and patches of heterochromatin appeared
resting on irregular basal lamina. Degenerated spermatocytes
with shrunken nuclei were also seen. Basal lamina was distorted
with collagen deposits. Sertoli cells cytoplasm contained scanty
mitochondria with loss of its cristae. Conclusion:
Prenatal exposure to flutamide has deleterious effect on adult
testicular function as regards spermatogenesis with proved
ultrastructural changes and pregnant females should be
instructed to avoid exposure to flutamide either as occupational
exposure or as therapeutic use.

Abstract:
Objectives: To evaluate the impact of weight reduction and
exercise interventions on ovulatory function of infertile
polycystic ovary syndrome (PCOS) women. Patients & Methods: 90
infertile PCOS women diagnosed depending on the Rotterdam
criteria underwent anthropometric measurements and determination
of body fat mass (FM), fat-free mass (FFM), and percent body fat
(BF%) using dual-energy x-ray absorptiometry.
Fasting
blood glucose (FBG), plasma insulin (FPI) and serum testosterone
(Test), sex hormone binding globulin (SHBG) were measured and
free androgen index (FAI) was calculated. Insulin resistance (IR)
was evaluated by homeostasis model assessment (HOMA) with
HOMA-IR score
>2 was considered
insulin resistant (IR).
All women performed
6-months weight-reduction dieting regimen in association with no
exercise (Group A), aerobic exercise (Group B) or combined
aerobic-resistance exercise (Group C). All measures were
evaluated at 3 and 6-months but ovulation was monitored monthly.
Results: At end of 6-months, all women showed significant change
of anthropometric measures with significantly higher extent of
change in groups B and C compared to group A. Also, IR was
significantly modulated with significant reduction of HOMA-IR
compared to pre-treatment levels; however, change was least in
Group A and only 15 of 63 women were still IR. Serum
testosterone and SHBG levels estimated at 6-m showed significant
difference compared to baseline levels in groups B and C and all
groups showed progressive decrease of FAI with significantly
lower FAI level in group B compared to group A. Fifty-nine women
got ovulation with ovulatory success rate of 65.6% with
non-significant difference among studied groups.
Conclusion: Weight
reduction regimens associated with aerobic physical exercise
intervention could induce weight loss and improve insulin
sensitivity with subsequent amelioration of inhibitory effect of
obesity and insulin resistance on the reproductive function and
adjustment of the hyperandrogenic milieu.

Abstract:
Objectives: To evaluate the outcome of single-setting
laparoscopic sleeve gastrectomy (LSG) and
uvulopalatopharyngeoplasty (UPPP) as a management policy for
Obesity-associated sleep-disordered breathing.
Patients &
Methods:
The
study included 23 obstructive sleep apnea syndrome (OSAS)
with body mass index (BMI) >40 kg/m2.
Preoperative
OSAS evaluation included Epworth Sleepiness Scale (ESS) and
polysomnography to determine the apnea-hypopnea index (AHI).
OSAS was
diagnosed if the patients demonstrated an AHI ≥15/h or ≥5/h
with an ESS ≥10.
Body
weight (BW) and BMI were evaluated at 1, 3 and 6 months
after surgery and
the percentage
of excess weight loss (%EWL)and the percentage of excess BMI loss (%EBMIL).
AHI and
ESS score were re-determined at 6 months after surgery and
percentage of change was determined. Results: Mean total theatre time was 105.3±10.7, mean time till first
ambulation was 2.5±0.7 hours, mean time for first oral
intake was 41±11.2 hours and mean hospital stay was 4.9±0.8
days. LSG and postoperative dieting regimen allowed
significant progressive BW reduction with a progressive
increase of %EWL and %EBMIL at 6 months after surgery
compared to percentages reported at 3 months after surgery.
Moreover, BMI strata showed progressive change with 21 women
had BMI <35 and only 2 had BMI >35 but <40 kg/m2.
Both ESS score and AHI evaluated at 6 months PO were
significantly reduced compared to preoperative measures. At
6-m after surgery, the mean percentage of decrease of ESS
and AHI were 66.3±10.5 (45.5-85.7%) and 80.4±7.5%
(67.2-91%), respectively. Conclusion: Combined LSG and UPPP
improved outcome of bariatric surgery for management of
obesity-related OSAS without prolongation of theatre time or
interfering with scheduled PO care of gastrectomy patients
and should be advocated for management of such patients.

Abstract:
This study was undertaken to evaluate the potential effect of
the brown alga Sargassum crassifolia against biochemical
and histological alterations in the muscles of fresh water fish,
Oreochromis niloticus, exposed to 1/10
LC50
(0.03 ppm) of Nimbecidin (azadirachtin). S.
crassifolia was added to the basal diet of fish in different
proportions (0, 10 and 25%) and the experiment lasted for 4
weeks. Exposure of fish to Nimbecidin
induced significant decrease in the activity of reduced
glutathione, catalase and in the total protein content of fish
muscles. Also many histopathological changes including
degeneration and necrosis,
disorganized myofibers with chromophobic cytoplasm, haemocytic
infiltration, oedema and inflammations were noticed in
Nimbecidine - treated fish. Exposing fish to Nimbicidin
and Sargassum crassifolia (10% and 25%) led to marked
improvement in the examined biochemical parameters together with
the histological structure of muscles. This improvement was
more obvious at high concentration of Sargassum crassifolia. In conclusion, the results of the present work
indicated that the brown alga Sargassum crassifolia had
ameliorative effect against muscle damage induced by Nimbicidin
and this may be mediated by its potent antioxidant activities.

Abstract:
Resistin, an adipocyte- and monocyte- derived cytokine that
thought to be the missing link between obesity and diabetes.
It also probably plays an important role in the development
of insulin resistance. This factor considered to play an
important role in the pathogenesis of type2 diabetes and
insulin resistance-related hypertension. Recently, gene
polymorphism is considered one of the most important factors
that determine occurrence of diseases. Resistin gene
polymorphism (UTR+62G>ASNP) may be a possible factor that
link the hypertension with type 2DM. Aim: We aimed to
investigate the correlation between resistin gene
polymorphism (UTR+62G>A SNP) with serum resistin levels and
if it is associated with insulin resistance-related
hypertension in high fat diet- induced diabetes in rats
(type 2 DM). Method: The current study was carried on 100
adult albino rats that have been divided into two groups.
Group I: included 20 rats that were served as control group.
Group II: that included 80 rats and they were given high fat
diet for 16 weeks. At the end of the study, the blood
pressure has been measured for both groups. Then the blood
samples were collected to examine the serum glucose level,
lipid profile level, serum resistin levels, the serum
insulin levels and the allele and genotype frequencies of
the single-nucleotide polymorphisms (UTR+62G>A SNP) in both
groups. Insulin resistance was determined using HOMA-IR. The
correlation of the gene variant to the hypertension, plasma
resistin and insulin resistance have been investigated.
Results: In the different
diabetic groups, there was a significant association of the
resistin A and G alleles of group IIb and group IIc when
compared to controls (X2=12.21, X2=46.88,
P=0.000) respectively. However, in group IIa the A and G
allele were not significantly changed when compared to
controls (X2=1.457, P=0.2). Serum resistin levels
were significantly increased in group IIa, group IIb and
group IIc in comparison with the control group (t=4.72, t=
9.82, and t=17.64/ P=0.000) respectively with a significant
increase in group IIc than group IIb (t=8.23, P=0.000).
There was a significant positive correlation between serum
resistin and insulin levels(r=0.939, P< 0.0001). In all
groups, rats with GG genotypes carriers were found to have a
significant increase of serum resistin, total cholesterol (TC),
fasting blood glucose (FBG), serum insulin levels and HOMA
index levels compared to AA genotype (P<0.0001). In
conclusion: This study suggested that, the 62G/A
polymorphism in resistin gene; genotype GG and G allele were
significantly associated with increased serum resistin
levels, hypercholesterolemia, increased insulin levels, and
also associated with increased risk of insulin resistance
and hypertension in obese diabetic rats.

Abstract:
Background: work- related neck disorders are a major health
problem in many occupations, so many epidemiological studies
dealing with them. The objectives of this study to determine the
prevalence of neck pain among communication company employees,
to explore some socio demographic and occupational risk factors
of neck pain, to plan for an ergonomic health education and
physical exercise programs and to evaluate the effect of this
program after 3 months using the same pre- test questionnaire. Subjects and methods: This study was carried out at the
governmental communication company in Zagazig city. One hundred
and thirty employees were randomly selected from the
workstations and were subjected to a pre-constructed
questionnaire included socio demographic, occupational and
Ergonomic features in the workplace. An ergonomic educational
program was applied after addressing the Northwick neck pain
questionnaire to measure neck pain and the consequent patient
disability. Evaluation of the program was done after 3 months.
Results: The mean age of the participants was 42.75+ 9
years, 58.5% were females, 80% were married and 91.5% were
nonsmokers. The percentage of chronic headache was 24.6%, the
majority of them had psychosocial troubles (70.8%). Neck pain
prevalence was 61.5%. The present study revealed that body mass
index had significant association with neck pain (p < 0.05).
Also employment duration, chronic headache, psychosocial
troubles and boring work had significant association with neck
pain. After application of the ergonomic health education
program the change in monitor level and keyboard position had
statistically significant difference. Neck pain had also
improved among communication employees after application
muscular exercise program. Conclusion: current study concluded
that there is a relationship between neck pain among computer
users and some risk factors as duration of employment, body mass
index, boring work, psychosocial troubles and chronic headache.
Application of Ergonomic Education program and neck physical
exercises can reduce neck pain among computer employees.
Recommendation: application of periodic ergonomic health
education programs for refreshing employees knowledge and
provide new employees with required knowledge also physical
exercise program should be a part of daily work schedule.
Further researches should be focused on risk factors of neck
pain among computer employees.

Abstract: Introduction: little is known about the health- related quality of
life (HRQOL) of patients with irritable bowel syndrome (IBS). Although
it is one of the most common gastrointestinal disorders. The
illness is characterized by chronic or recurrent abdominal pain
and altered bowel habits. These symptoms can adversely affect HRQOL of people who suffer from IBS. Objectives of this study:
to assess QOL of females with irritable bowel syndrome and to
find the relationship between severity, duration and types of
IBS and QOL. Subjects and methods: a case – control study, 93
Female patients suffer from (IBS) attending internal medicine
outpatient clinic of Zagazig University Hospital were included
in this study, compared to control group(93 females). Data was
collected using 1- structured questionnaire covering some
socio-demographic data, 2- Rome11 criteria of IBS diagnostic
questionnaire, 3-a generic QOL (SF 36) questionnaire. Results:
females with IBS had worse QOL of physical functioning, role
limitation due to physical health, role limitation due to
emotional problems, vitality, social functioning, pain,
emotional wellbeing and general health perception compared to
controls p<0.05. Female patients suffered from severe IBS
symptoms had a significantly poor QOL of domains (physical
functioning, pain and emotional wellbeing) compared to IBS
female patients reported moderate symptoms (p<0.05). Diarrhea-
type and mixed- type IBS female patients had worse QOL of the
three domains (role limitation due to physical health, role
limitation due to emotional problem and emotional wellbeing) than constipated- type of IBS patients p <0.05.Also there was
negative significant correlation between duration of IBS and QOL
of IBS female patients in domain of physical functioning, role
limitation due to emotional problems, social functioning,
pain and vitality (r - 0.4, - 0.24, - 0.33, - 0.39, -0.34) respectively p < 0.05. Conclusion: and recommendation: IBS-
symptoms had a great effect on the QOL of female patients so
early detection may improve the progress of health problem and
decrease the burden of disease on health service. So there is a
great need to include QOL as a tool during assessment and
evaluation of IBS patient

adeladel59@yahoo.com
Abstract:
Objectives: The
present study aimed to evaluate the impedance to the ductus
venosus (DV) flow and the pulmonary vein pulsatility index (PVPI)
in fetuses of diabetic mothers with and without myocardial
hypertrophy (MH) in comparison to control fetuses of
non-diabetic mothers. Patients & Methods: The study included 100
pregnant women; 50 diabetics and 50 non-diabetics of the same
gestational age. Prior to cardiological evaluation, the fetal
anatomy was analyzed using ultrasound assessment to rule out
malformations and fetal biometry. Fetal echocardiographic
examinations were conducted for assessment of ventricular septum
thickness (VST), ductus venosus pulsatility index (DVPI), mitral
and tricuspid atrioventricular flows and pulmonary vein flow
studies were also conducted. Results: Mean VST was significantly
increased in fetuses of diabetic mother (FDM) compared to its
thickness in non-diabetic group and 19 fetuses had VS
hypertrophy (VSH) with significantly thicker VS compared to FDM
free of VSH. FDM showed significant increase of DVPI compared to
fetuses of non-diabetic mothers (FNDM) with significantly higher
index in those had VSH. Mean mitral and tricuspid E wave peak
flow was significantly higher in FDM compared to FNDM. Pulmonary
vein pre-systolic flow showed a significant decrease and PVPI
was significantly higher in FDB compared to FNDM. Conclusion:
Maternal hyperglycemia induces ventricular hypertrophy that
increases impedance to blood flow through cardiac chambers
manifested as increased ductus venosus and pulmonary vein
pulsatility indices.

*shindy_Fahmy@yahoo.com
Abstract:
Objectives:
To screen
subjects seeking for medical advice for their obstructive
sleep apnea (OSA) or erectile dysfunction (ED) who consider
themselves healthy as regard to ED or OSAS, respectively for
the prevalence of each disease among the other group.
Patients & Methods: The study aimed to include all male
patients attending Urology outpatient clinic with sexual
problems without certain complaint or comment of their sleep
behavior (Group A) and all patients attending
Otorhinolaryngology outpatients clinic with snoring
complaints without certain complaint or comment of their
sexual function (Group B).
Sleep problems
assessment was conducted using a sleep questionnaire and
subjects were categorized as heavy, moderate and none/mild
snorers.
Erectile function was assessed using the International Index
of Erectile Function (IIEF-5) questionnaire for a total
score of >25 is graded as normal erectile function (EF).
Sexual
function was assessed using the Brief Male Sexual Function
Inventory (BMSFI).
Results: The study included 494 clinic attendants Group B
subjects had significantly higher mean body mass index.
Among Group A 37 subjects were normal, 127 had mild, 54 had
moderate and 29 had severe ED and according to OSAS
questionnaire 116 subjects had
low-probability
of OSA,
69 had
intermediate-probability
and 62 had
high-probability of OSA. Among Group B
155 subjects had
low-probability
of OSA,
53 had
intermediate-probability of OSA
and 39 had
high-probability of OSA
and according to IIEF questionnaire, 85 subjects were
normal, 81 had mild ED, 53 had moderate ED and 28 had severe
ED. There was negative significant correlation between OSAS
grade and IIEF-5 score in attendants of both clinics. ROC
curve analysis of OSAS grades as predictor for presence of
ED showed that just presence of OSAS could be used as
screening test for presence of ED among subjects not
complaining of ED with area under curve of 0.329.
Conclusion: OSAS could be considered as an underlying
pathogenic factor for later development of ED in male OSAS
patients. IIEF-5 is a valid screening tool for ED and must
be implemented during evaluation of OSAS patients and sleep
disorders evaluation must be considered for patients with
ED.

Abstract:
A critical care unit is a high-technology environment. The use
of technological devices can ensure better outcomes for
patients’ health and decrease morbidity and mortality. The
critical care nurse needs not only to be aware of what benefits
the technology holds for the patient, but also what adverse
effects. The aim of the study is to assess the nurse's
perception regarding the use of technological equipment in
Critical Care Units. A descriptive study research design
used in this study; this study was conducted in the critical
care units of Main University Hospital in Alexandria, A
convenient sample of all bed side nurses -102 nurses- who are
working in this unit, and were available at the study time.
Nurse's
perception questionnaire regarding the use of technological
equipment in Critical Care Units was used in this study.
The
results of this study revealed that nurses who work in critical
care areas of Main University Hospital in Alexandria identified
all positive aspects of using technological equipment and were
not aware about most of the negative aspects of using
technology.
It is recommended
courses about
contemporary aspects of technology should be added to both
pregraduate and continuing education. Further researches needed
for investigate effect of the nurses' perception about using
technology on patients.

Abstract:
Supplier selection or vendor selection is a complicated
multi-criteria decision-making including both quantitative and
qualitative factors. In order to select the best suppliers it is
important to make a trade-off among these factors, some of them
may conflict. The buyer should determine two important
variables: the number of best suppliers and the amount of
purchasing from each selected supplier. In this paper an
integrated approach of Multi-Attribute Utility Theory (MAUT) and
Linear Programming (LP) is proposed for supplier selection
problems when a buyer needs more than one product. Also, a Mixed
Integer Linear Programming (MILP) approach is applied in a
discount environment to determine the best suppliers and to
place the optimal order quantities among them. Both cumulative
and incremental discounts are taken into account in this study.
Two numerical examples are presented for each discount policy to
illustrate the application of the recommended models which in a
reasonable time reach to an exact solution.

Abstract:
Background: The atmosphere in poultry farms usually contains
significant levels of agricultural dust and toxic gases, which
put the workers at a health risk. Objectives: 1-To determine the
prevalence of some occupational health problems among poultry
farm workers and their determinants.2-To study the work
environment by assessing dust concentration level and its effect
on the health of the exposed workers.3-To propose
recommendations for occupational safety at poultry farms.
Methods: a comparative cross sectional study was conducted among
222 male workers divided into two groups: The exposed group
consisted of 110 poultry farm workers working in 63 poultry
farms in Diarb Nigm city and Comparable control group consisted
of 112 workers from ready- made clothes factory. Data were
collected by a pre-designed questionnaire, clinical examination
and laboratory investigation. Results: self–reported health
complaints among poultry farm workers were ocular complaints
(55.4%), followed by gastrointestinal (48.2%), respiratory
(41.8%), and dermatological (38.1%) complaints. The prevalence
of nasal irritation, sneezing, throat irritation and chest
tightness were significantly higher among the Poultry farm
workers (21.8%, 20.9%, 27.2%, 15.4% respectively) compared to
control group. Also, prevalence of chronic cough, chronic
phlegm, chronic bronchitis and bronchial asthma were
significantly higher among poultry farm workers (39.09%, 38.18%,
16.3%, 6.3% respectively) compared to control group. Duration of
work is a risk factor for respiratory symptoms (chronic and
acute), while smoking is a risk factor for chronic respiratory
symptoms. The frequency of obstructive and combined ventilatory
function impairment among poultry farm workers (26.3%, 14.5%)
are significantly compared to control group (8.9%, 5.35%). The
prevalence of chronic dermatitis, onychomycosis and tinea pedis
are significantly higher among exposed group (15.45%, 18.18% and
20% respectively) compared to in control group (4.46%, 3.57% and
8.03% respectively). The prevalence of eye irritation &
lacrimation, discharge and Foreign body is significantly higher
among exposed group (22.7%, 14.4% and 54.54%) compared to
control group (6.25%, 3.57% and 5.35%). Also The prevalence of
Klebsiella and E-coli are significantly higher among exposed
group (18.05% and 88.8%) compared to control group (1.755 and
14.03%). The mean concentration of respirable dust at poultry
farms was (5.5±1.62). Conclusion: Poultry workers are at
greatest risk of developing many health problems as respiratory,
ocular, dermatological, gastrointestinal problems, so
recommendations: pre-placement and periodic medical examination,
health education program, effective exhaust ventilation, and
periodic environmental monitoring for better prevention for
these health problems.

Abstract:
In general, the behavior of most of materials is studied in
terms of their mechanical properties like as compressive and
tensile strengths; however, to study the behavior of fiber
reinforced concrete, these properties is not enough and the
flexural strength and the energy absorption capacity of the
concrete should also be studied. The effect of polypropylene
fibers of different lengths and diameters on the flexural
strength of the concrete has been explored in this article.
The variables of the experiments include three lengths for
fine polypropylene fibers and two lengths for thick
polypropylene fibers. Results indicate the flexural strength
of the samples increased with increasing the fiber's length.
But by addition fine polypropylene fibers, the flexural
strength of the samples decreased with increasing the
fiber's length. On the other hand, the addition of fibers
polypropylene to the concrete can not be effective in
enhancing the cracking load of the the concrete, but thick
polypropylene fibers can increases the ultimate load after
cracking and the energy absorption capacity of the concrete.

Abstract:
In this paper,
an efficient pose-invariant face recognition method is proposed.
This method is multimodal means that it uses 2D (color) and 3D
(depth) information of a face for recognition. In the first
step, the geodesic distances of all face points from a reference
point are computed. Then, the face points are mapped from the 3D
space to a new 2D space. The proposed mapping is robust under
the in-depth face rotations. Finally, the feature extraction and
face classification task is done in the new 2D space. For
feature extraction, we use the Patch Pseudo Zernike Moments (PPZM)
with a new weighting method to decline the self-occlusion caused
by in-depth rotations. For this purpose, a novel approach for
self-occlusion detection based on geodesic distances of face
points is proposed and a self-occlusion map is created. For
evaluation purpose, a large scale 3D face database is used and
the various in-depth rotations (vertical and horizontal) are
tested. The performance of the proposed method in two scenarios
is compared with a classical 3D face recognition method. The
results emphasize the performance of the proposed method in the
pose-invariant face recognition.

Abstract:
To understand the impact of water deficit stress and nitrogen
application on the evergreen flower yield, the experiment was
laid out as
a randomized complete block design with split-plot arrangement.
Soil-water regimes consisted of three levels (irrigation after
40_normal stress, 80_mild stress, and
120-severe stress mm evaporation from class ‘A’ pan) which
allotted to the main plots and Nitrogen rates including 0, 30,
60, and 90 kg N/ha were assigned to subplots. Six drought
resistant indices include mean productivity (MP), geometric mean
productivity(GMP), stress tolerance index(TOL), susceptible
stress index(SSI), stress tolerance index(STI) and harmonic
mean(Harm) were applied on the basis of flower yield in normal,
mild and sever stress condition. Evaluation of different
nitrogen application rates by the means of drought tolerant
indices asserted that, the highest flower yield under
mild/severe stress was achieved via treatments which received 90
kg n/ha. 3D scatter plot results were also cleared the
superiority of the same rank of nitrogen application as the best
level. Correlation coefficients between indices and yield under
stress /non-stress conditions showed that GMP, STI, MP, Harm and
TOL under mild stress, in addition SSI, Harm, GMP, STI, MP and
TOL under severe stress were the most effective level
identifying indices.

Abstract:
In this paper the dynamic load balancing strategies are
discussed to minimize the execution time of single applications
running in parallel on multicomputer systems. Dynamic load
balancing is important for the efficient use of parallel
systems. Dynamic load balancing schemes are needed to solve
non-uniform problems on multiprocessor systems. Distribution of
the work load is known as Load Balancing. An appropriate
distribution of workloads across the various processing elements
is very important as disproportional workloads can eliminate the
performance benefit of parallelizing the job. Load balancing on
parallel systems is a critical and challenging activity. Load
balancing policies may be categorized as static or dynamic.
Static load balancing algorithms distribute the tasks to
processing elements at compile time and are generally based on
the information about average behavior of the system, while
dynamic algorithms bind tasks to processing elements at run time
and react to the actual current system state in making transfer
decisions.

Abstract:
Fine grained, saline, alkaline
and erodible Tertiary marly formations are exposed in many
geological zones and they play an important role in the
formation of present landform structures. Marly formations as
one of the most critical sediment resources, will always pose
special problems on watershed management. Due to special
mineralogical and geological formulation of these formations,
they are intolerant to erosion and their minerals contents
affects their behavior from the view point of erosion and
sediment production which are important factors on land
degradation. Investigating the causes of soil erosion is
difficult in natural conditions owing to the presence of other
factors. Without simplifying the experimental conditions,
studying soil behavior regarding its numerous factors such as
vegetation cover, topography, and rainfall is not impossible but
difficult. The application of simulation approaches is therefore
necessary to simplify the prototype. In this research, the
effects of some physical soil factors such as texture along with
land slope were evaluated in the Qezel-Ozan watershed of Zanjan
province, Iran, using a rainfall simulator and soil erosion
plots. For this purpose, a 89 × 120 cm rainfall simulator
producing 60 mm/h rainfall intensity of 30 min duration, as a
common condition of the study area, was used at 64 locations
over soil erosion plots with dimensions of 95 × 125 cm. Plots
had slope classes of 5 and 20 percents, and different soil
textures. It was found that for 60 mm/h rainfall intensity, the
correlation coefficient of 0.047 between sand and sediment yield
for 60 mm/h rainfall intensity indicate very low correlation.
Percentages of slope, clay and silt content had correlation
coefficients of 0.689, 0.329 and -0.233 respectively at the 99%
confidence level with sediment yield. The correlation
coefficients of 0.861 in equations indicate their high potential
in simulating sediment yield.

Civil
Engineering Department, Menoufiya University, Egypt
Abstract: Repair and strengthening of the existing constructions are very
essential in many cases and may be the sole right decision. A computer program based on the finite element method has been
developed and a new compound element was used to simulate the
reinforced concrete members strengthened with external layers on
the different sides. Each compound element consists of four
sub-elements. The sub-elements are two dimensional isoparametric
degenerated elements with eight nodes and five degrees of
freedom. Each sub element consists of different concrete, steel
and strengthening laminates. Seven models from an experimental
test program of RC beams strengthened with external layers in
different sides were analyzed by the finite elements. The new
developed compound element has been proved to be capable to
solve any reinforced concrete member strengthened with
additional external layers at different sides with accurate
representations and acceptable results.

Abstract:
Central venous cannulation is associated with many
complications. The recent literature suggests that there is a
close relationship between peripheral and central venous
pressure readings. This prospective comparative study is
designed to investigate the agreement between central venous
pressure (CVP) and peripheral venous pressure (PVP) and
investigate the effect of intravenous catheter placement on the
risk of complications in critically ill patients. Sixty
patients were enrolled in the study as soon as they had a
central venous catheter in place. They were cannulated at the
antecubital site with a 20- gauge peripheral over- the needle
intravenous catheter at the same time of central venous catheter
insertion. Assessment of risk of complications of both
peripheral and central venous catheters was done using the
infiltration scale, observation of exit-site infection,
assessment of catheter occlusion as well as bacteriological
examination. Peripheral and central venous pressure readings
were monitored immediately after insertion of both central and
peripheral venous catheters and then every 6 hours for 3 days.
Temperature and blood pressure were measured before each
measurement. The results showed that PVP was closely correlated
to CVP (r = 0.92 to 0.98). Significant relation was found
between CVP and PVP at different times of measurement. PVP was
consistently greater than CVP by an average of 2 mmHg.
(P<0.001). Catheter colonization was significantly higher among
patients with central venous catheters (CVCs) (P<0.01). Catheter
malfunction was higher in CVCs. Infiltration occurred more often
with peripheral venous catheters (PVCs). The findings indicated
that peripheral venous catheters can be used instead of central
venous catheter for estimation of body volume status and
minimize central catheter complications.

Phylogenetic
Relationship between the Fruit Bat (Rousettus Aegyptiacus)
and Lesser Tailed Bat (Rhinopoma Hardwickei) Inferred
from G-Banded Chromosomes and Electrophoretic Protein Pattern
Analysis

Abstract:
The present work is an attempt to find out both the genetic
similarities and the divergences between the Fruit bat (Rousettus
aegytiacus) and lesser tailed bat (Rhinopoma
hardwickei) by using G-banding technique for bone marrow
metaphase chromosomes and sodium dodecyl sulphate polyacrylamide
gel electrophoresis (SDS-PAGE) for liver protein. The diploid
chromosome number (2n) for each of these two species is 36
chromosomes and NFa is 68 arms. The chromosomes of both two
species are grouped in 17 pairs, in addition to the sex
chromosomes. The relative lengths of the X chromosome and the Y
chromosome are 5.6 % and 6.4 % in the fruit bat respectively and
The relative lengths of the X chromosome and the Y chromosome
are 0.7 % and 1.2% in the lesser tailed bat respectively. The
G-banding displays obvious alternations of white and dark bands;
this facilitates ideogram construction. The sequence of banding
pattern of chromosomes of the 2 species display fairly similar
and different pictures. SDS-PAGE for soluble muscle protein
showed 23 and 19 protein bands in the, Rousettus aegytiacus
and Rhinopoma hardwickei respectively. The two species
have 2 common bands. The
molecular weight of the bands ranges from 118-26 kDa and from
118-24 kDa in the Rousettus aegytiacus and Rhinopoma
hardwickei, respectively. Bands of molecular weight
70,60,50,42,36,31,29 and 27 kDa are characteristic to the
Rousettus aegytiacus and are missed in the Rhinopoma
hardwickei. Also, bands of molecular weight 113,105, 65 and
24 KDa are characteristic to the Rhinopoma hardwickei.
Moreover, the unique band at molecular weight 113 is
characteristic to the Rhinopoma hardwickei. The
statistical analysis showed that the degree of similarity
between the two species is 0.095(9.5%). As a conclusion, the
Fruit bat (Rousettus aegytiacus) and the Lesser
tailed bat (Rhinopoma hardwickei) are not identical
and separated species.

Abstract:
Education
in the direction of improvement management cycle (IMC)
establishment and being careful about good management methods
for upgrading educational system productivity based on free
economy, as a big social evolution, with the development of
educational market and movement of capital flows and by
elimination of shortcomings to the educational realm has
provided increased productivity. It has been increased by
providing private section investment settings in educational
system and took step in the development of private section role
in managing schools and expanding private education to
entrepreneurship, more occupation, state employees' inflation
prevention, and downsizing government. Since the share of public
section in global education is something between 20% to 30% and
the highest share of Iran private education before Islamic
Revolution in 1971 had been 10.4%, in 1388 it was 8.07%. Also,
by paying attention to the downward growth rate, which is lower
than expected global average, by privatization of education, we
can take an important step in promotion of productivity,
consistent with improvement management cycle, and access to the
synchronized growing with other countries.

Hardwickei) Deduced From RAPD-PCR Analysis
Ramadan A. M. Ali
Department of
Zoology, College for Women, Ain Shams University, Cairo, Egypt
ramadanali27@gmail.com
Abstract:
The RAPD-PCR in the present study was used to determine the
genetic variation within and among two Egyptian bat species,
Rousettus aegyptiacus and Rhinopoma hardwickei. The
animals were captured from one locality at Giza governorate,
Egypt. A total of 39 bands were amplified by the three primers
OPAO2, OPAO8 and OPCO3 with an average 13 bands per primer
at molecular
weights ranged from 1409 to 107 bp. The polymorphic loci between both species were 34 with
percentage 87.18 %.
The numbers of monomorphic bands in Rousettus aegyptiacus aegyptiacus
and Rhinopoma hardwickei arabium were 14 and 9 bands,
respectively. The two species are sharing 5 (12.8 %) monomorphic
bands. The
similarity coefficients value between the two bat species was
ranged from
0.353 to 0.500
with an average of
0.404 (40.4%).
Dendrogram showed
that, the two bats genotypes are separated
from each other
into two
clusters and
more variation
among members of Rhinopoma hardwickei
arabium
was observed
in comparison to
those of Rousettus aegyptiacus aegyptiacus. It is
concluded that, the similarity coefficient value between the two
bat species indicates that, the two bat species may have the
same origin but are not identical and separated into two
clusters.

Branch, Marvdasht, Iran
Marzbanf31@yahoo.com
Abstract:
The present
study has been designed to investigate the relationship between
professional morality and maturity with organizational
commitment of board members of Azad University in Marv Dasht
branch. The main purpose of university includes training and
educating expert human forces that are necessary for a society,
and providing appropriate grounds for constant development of
the country. In this respect, board members of the university
are the most effective factors to fulfill this aim. Universities
are expected to develop professional morality and maturity of
all board members and they should plan everything in order to
facilitate the promotion of their board members and it is
effective in organizational commitment of them. Professional
morality and its subordinate elements have a positive and
meaningful relationship with organizational commitment and its
aspects. The element of evolution in morality has the strongest
constant relationship with organizational commitment and its
aspects of emotional commitments. Therefore, in order to
increase the organizational commitment, this element of morality
should be emphasized more. The positive relationship between
professional moral elements and organizational commitment means
that as the elements of professional morality increase, the
organizational commitments and its aspects increase as well.
Investigation on the relationship between maturity and its
elements and organizational commitment and its sides shows that
of all maturity elements, professional maturity has no
meaningful relationship with norm commitment and other elements
have a positive relationship with organizational commitment. It
means that as maturity and its aspects increase, organizational
commitment and its aspects increase as well. Of all maturity
elements, organizational maturity has the strongest relationship
with organizational commitment of university board members of
Marv Dasht Azad University. It illustrates that this cultural
path is organizational which build up individuals’ behavior.

Objective:
The purpose of this study was to determine the effect of
endurance, resistance and concurrent training on the serum
levels of interleukin 15(IL-15)
and insulin-like growth factor-1(IGF-1)
in adolescent females.
Methods:
Twenty seven
girls randomly were selected from among 150 adolescent girls.
Then, they randomly were divided to four groups of resistance
(n=7), endurance (n=7), concurrent (n=7)
and control (n=6). The
training programs of the groups lasted for 8 weeks, three days
per week, which were performed from simple to difficult
exercises and from low-intensity to high-intensity considering
the principle of overload and increase in exercise intensity.
Blood samples were taken before, in the middle and after the
training program and IGF-1 and IL-15 variables were measured.
Statistical analyses used were
ANOVA with repeated
measures (split-plot or mixed factorial
test).
Results:
The results showed that eight-week resistance training made
no Significant difference of IL -15 in the pre, mid and end of
study protocol into the control, endurance and concurrent
training groups. But was found a significant increase in
concentration of IL -15 in three stages
(pre-mid, and end test) in the resistance group

Effects of
essential fatty acids on ruminant animal: A Review
Hamed AminiPour
Young researchers club, Sarab
Branch, Islamic Azad University, Sarab, Iran.
h.aminipor@gmail.com
Abstract:
Previous work on the relationship between chemical structure and
biological activity of fatty acids was based on the theory that
either the 6-term. (That is, a double bond between the 6th and
7th carbonatom counted from the terminal methyl group) or the
9-term. Double bonds or both were fundamental for essential
fatty acid activity. By means of a new quantitative bioassay a
number of fatty acids were tested and the results were in favors
of the theory that both the 6-term. And the 9-term. Positions
are essential.
Although
essential
fatty acids
(EFA)
are not
vitamins by
definition, a deficiency disease
or condition
with
dietary insufficiency
does
result, and in some ways,
a similarity
to
vitamin deficiencies
can be
seen. The
finding that
components of
fat, other
than
the fat-soluble
vitamins,
are dietary
essentials
is of
nutritional and medical
importance. Studies are reevaluating
the
beneficial effects
of linolenic acid
in
species that
previously were
considered
to need
only linoleic acid
as a
dietary essential.

EFFECTS
OF
TANNINS
IN
RUMINANT: A
Review
Hamed AminiPour
Young researchers club, Sarab
Branch, Islamic Azad University, Sarab, Iran.
h.aminipor@gmail.com
Abstract:
Tannins
are
very
diverse
chemically,
are
widely
found
in
plant
material
and
can
have
diverse
effects
on
animals
which
consume
them.
This
mini-review
has
the
aim
to
investigation and
discusses
information
available
in
the
scientific
literature
on
the effects
of
condensed
tannins
on
ruminant
nutrition.
Polyethylene
glycol
(PEG)
has
been
used
in
most
experiments
to
deactivate
condensed
tannins (CT).
The
effects
of
dietary CT
on
nutrition
have
been
studied
principally
with
tannins
from
temperate legume pastures.
At
low
concentrations,
CT
appear
to
increase
intake
because
of a
reduced
protein degradation
in
the
rumen
and
better
amino
acids
supply
to,
and
absorption
from,
the
small
intestine.
CT
from Lotus
corniculatus
increased
milk
yield,
protein
and
lactose
percentages,
and reducing
fat
percentage.
Regarding
carcass
characteristics,
CT
from
temperate
plants, at
low
concentrations,
have
increased
carcass leanness
and
reduced
carcass
fatness.
This
can
be
due
to
improved
protein
nutrition due
to an
increased flow
of protein and
essential
amino
acids
to the
intestine.
Condensed tannins
from
Acacia
cyanophylla
had
no
significant effects
on
lamb
tissue
repartition.
Meat
quality
has been
evaluated
after
lambs
received diets
containing CT
from
this
shrub
species
or
Ceratonia
siliqua pulp
with
or
without
PEG.
In
both
cases,
lean
color appeared to
be
greatly
affected
by
dietary
CT,
being
darker
in
the
animals
that
receive
PEG
supplementation. The
effect
of
CT
on
meat
color
could
be
linked
with
a
reduced
myoglobin
synthesis
although
iron absorption
seems not
to be
affected by
CT
in
ruminant.

after 100 mm, I3-Irrigation
after 130 mm and I4-Irrigation
after
160 mm
evaporation from class A
pan) and two dates of
sowing (August 30 and January 27) were studied during growing
season of 2009-2010 at I.A. University of Takestan, Iran. Among
the irrigation treatments, irrigation after 70 mm evaporation
from class A pan, gave significantly highest plant height,
seed/siliqua, siliqua/plant, thousand seed weight and seed
yield. The highest seed yield of 3034 kg/ha was
obtained from August 30th sowing and decreased gradually
thereafter.
Findings suggest that,
further research should be done on planting date of Indian
mustard under different environmental conditions.

Abstract:
A renewed focus on energy security arises from an extremely
tight oil market and high prices that are driven by long-term
trends in global growth and political-economic rivalries. While
global energy markets are well developed, the institutions
associated with stable investment and exchange are poorly
developed in most energy producing countries. Moreover, many
have a history of conflict or are located in regions where
conflict is rife. Some leaders of energy producing countries
threaten to use energy supplies to achieve geopolitical rather
than economic objectives. Yet our theories about the new
institutional economics of growth are based on evidence about
countries that were developing in a more stable environment.

Abstract:
A series of 3,5-diaryl-Δ2-pyrazolines (2a-h)
were prepared by the reaction of 1,3-diaryl-2-propen-1-ones
(1) with hydrazine hydrate and used as precursor for the
preparation of 1-acetyl-2-pyrazolines (3a-d). A series
of1,3,5-triaryl-2-pyrazolines (6a-h) and (7a-g)
were prepared by the reaction of 1,3-diaryl-2-propen-1-ones
(1) with phenyl hydrazine and/or 2,4-dinitrophenylhydrazine.
Similarly, 3,5-diaryl isoxazoline derivatives (9a,b) were
prepared by the 1,3-cyclocondensation of
1,3-diaryl-2-propen-1-ones (1) with hydroxylamine
hydro-chloride. Also 1-carbamoyl-, and
1-thiocarbamoyl-2-pyrazoline derivatives (8a-e) and
(8f-j) were synthesized. The structures of the new compounds
were proved by means of their IR, 1H-,13C-NMR,
MS spectroscopic data and microanalysis. All the new compounds
were examined for their in
vitro antimicrobial activity. Some newly synthesized
compounds were examined for their in vitro
anticancer activity. In the present investigation, we discuss
the structure-activity relationships and biological activities
of these compounds.

Abstract:
Diplomatic
protection is to be understood as the protection given by a
subject of international law to individuals, i.e. natural or
legal persons, against a violation of international law by
another subject of international law
[1]. The essential elements of diplomatic protection
which must be considered in any case in international court of
justice (ICJ) for stating its Jurisdiction are state hood of
parties, Nationality of individual, Home state, Continuity of
nationality, and Pre requisite conditions of diplomatic
protection. Diplomatic protection can originally be seen
as belonging to the study on state responsibility, which is
mainly based on customary international law, but has been
influenced by some important changes in respect of non –
nationals protection specially, " stateless Persons, refugees
and human rights violation". Diplomatic protection
dealing with the legal consequences of an internationally
wrongful act and responsibility of the states for making full
reparation for the injury caused by an international delict,
this reparation may take the form of "restitution, compensation
or satisfaction", either singly or in combination which is
determined by the court.This paper analysis the prerequisite
conditions for obtaining court jurisdiction and admissibility in
diplomatic protection of legal persons with respect to Mr.
Diallo case.

Abstract:
Earthquakes are
a natural hazard that causes extreme damage to property and
life. The Bam, Iran earthquake has been considered as one of the
largest disasters that ever occurred between 2000-2011. With an
estimated loss of $15 billion in property and 26,000 loss of
lives, there is no doubt that measures have to be taken by Iran
in order to reduce the impacts of natural hazards such as an
earthquake risk reduction plan should another earthquake hit the
nation. The research employed the Case Study Method wherein the
Bam, Iran earthquake was used to identify the possible measures
for earthquake impact reduction. Gathering of secondary
materials and data from books, magazines, and journals was also
employed to acquire additional information on the incident. From
the research done, it has been found out that disaster
preparedness has to be practiced such as the use of GPS (Global
Positioning System) in order to monitor crustal movements that
signal the coming of an earthquake a geographical mapping can
also be employed in order to identify fault lines and other
earthquake-prone areas. There should also be a geophysical
investigation of areas in order to pinpoint the kind of soil
where the buildings are to be erected. This is important since
the strength of the soil to hold the building up during an
earthquake can help reduce the impacts of earthquakes. The use
of Fiber Reinforced Polymer (FRP) to Unreinforced Masonry (UTM)
should also be made imperative. The addition of FRP greatly
increases the strength of the buildings.

University, Egypt *Moh_abo_elaa@yahoo.com
Abstract:
Background & aim:
Facial measurements have been used by numerous researchers
to produce standard mean values for skeletal, dental, and
soft tissue structures. This has become useful in the
classification of different populations. So, the present
study was permitted to establish the mean vertical facial
dimensions and indices of adults in Upper Egypt represented
in Assiut Governorate in Egypt. Also, this study was carried
out to establish the sexual differences of some vertical
facial dimensions and indices between the adult males and
females in the fore- mentioned locality.
Subjects and Methods:
In the present study, 478 adult subjects were studied for
some vertical facial dimensions and indices in Assiut
Governorate of Egypt. They were between the ages of 18-69
years, divided into 9 groups (from I- to - IX) and
included 256 males and 222 females. Four parameters and
three indices had been carried out in the present study. The
parameters included the nasal height or upper facial height
(UFH), the nasal width (NW), the lower facial height (LFH)
and the total facial height (TFH). All measurements were
carried out with the help of a sliding caliper. The three
indices included the upper facial index (UFI), the lower
facial index (LFI) and the nasal index (NI).
Results:
In the present study the highest value of the UFH, NW, LFH
and TFH in both males and females was observed in age group
V (34-to-37 years of age group) while the lowest was
observed in age group IX (50 -to-69 years of age group). The
UFI was ranged from 39.41 % to 40.67 % for males and from
39.4 % to 40.55% for females between group I and group IX. For LFI, the value was 59.41 % for males and 59.16 % for
females in group I, while it was 60.71 % for males and
60.66% for females in group IX. The present study
revealed
higher values of UFH, LFH, TFH, UFI, LFI and NI for males
when compared to that of females. This higher values was
significant for UFH, LFH, TFH and NI (P= 0.018, 0.05, 0. 011
&0.048), while it was non significant for UFI and LFI.
The results showed that, on the average, the
UFH for adult males was found to be 4.8 ± 0.17 cm and 4.01
± 0.14 for adult females. The LFH of adult males was found
to be 7.18 ±0.09 cm while that of adult females was found to
be 6.81 ± 0.07 cm. The TFH showed mean values of 11.98 ±
0.41 for males and 11.33 ± 0.18 for females. The average UFI
in the present study was 40.09% ± 1.7 for males and 40.0% ±
1.3 for females. Furthermore the average LFI in the present
study was 59.93% ± 2.1 for males and 59.99% ± 2 for females.
Statistical analysis of mean and standard deviation
indicates sexual dimorphism, with significantly higher value
(p ‹ 0.05) of the average UFH, LFH and TFH in males compared
to females of the corresponding ages.
Conclusion:
This study has been able to establish the mean facial
dimensions of adults in Upper Egypt represented in Assiut
governorate. It also established that as in other
populations facial parameters are sexually dimorphic among
the peoples of Upper Egypt and that male facial dimensions
are greater than those of females. Knowledge of vertical
facial dimensions is important in evaluation of age, sex and
racial differences, in clinical applications and in forensic
application.

Abstract:
The study aimed to compare the socio-demographic
characteristics, obstetrical complications and fetal outcomes in
delivered booked mothers with those unbooked and to determine
the relationships with maternal and perinatal outcomes. In a
prospective study over 1 year period outcomes of pregnancies of
women booked for antenatal care were compared with those of
unbooked women, who delivered in Zagazig University Hospital. A
sample of 218 women (booked mothers) and 80 unbooked mothers was
selected from labor unit in Zagazig University Hospital. The
study tools included a questionnaire sheet, maternal assessment
sheet until delivery, post-delivery, and neonatal assessment
using newborn weight and gestational age. The data were
collected from November 2010 to October 2011. The results
revealed that pregnancy complications anemia had a higher
prevalence in unbooked mothers and the preeclampsia, unbooked
mothers were less likely to deliver by spontaneous vaginal
delivery. Unbooked mothers were twice as likely as booked
mothers to deliver preterm babies. Babies of unbooked mothers
were twice as likely as booked mothers to have asphyxia as
indicated by an Apgar score of <7 at one minute and five
minutes. Conclusion: The study showed a positive
correlation between unbooked mothers and an increased risk of
maternal and fetal adverse outcomes.

Abstract:
Fe2O3, SiO2, TiO2
and TiO2/SiO2, Fe2O3/SiO2
core–shell nano particles were used to decompose methylene blue
(MB) in a laboratory scale study prior to its use in the
treatment of waste containing azo dyes that may potentially pose
adverse environmental consequences and health hazard to human.
The preparation of TiO2, Fe2O3
cores produced perfectly spherical and smooth surfaces of
associated silica shells.
The percent degradation of Methylene blue (MB) was measured and
found to reach 98% using SiO2 in 300 min. The
corresponding percent degradation using TiO2 and TiO2/SiO2
reached 95% and 81% respectively for the same time period. The
results obtained using Fe2O3 and Fe2O3/SiO2
core–shell particles were not encouraging.
