Abstract: In this
paper it has been attempted to study active intellect, human
intellect and characteristics of human intellect in Ibn Sina
views. Intellect is a spiritual and subtle essence whereby human
soul perceive essential sciences and due to it become
knowledgeable, intellect needs to body and physical powers in
all of its actions while theoretical intellect doesn’t need to
the body all the time and all sides but it is sometimes
self-sufficient by nature.

Abstract:
Abstract:
Drug abuse remains a
critical problem in most countries and is associated with
several social and economic consequences. Addiction has grown to
such proportions that it has become a priority health problem
and a serious threat to the stability of social, political and
legal instructions in many countries.
The aim of the study: The study aimed to
identify the psychological
distress and social support among substance abused patients.
The study was carried out
in the Psychiatric Mental
Hospital at Assiut governorate, Egypt.
Subjects and methods: The study sample comprised
50 addict patients and 50 persons as a control group.
Five tools were used for data
collection, namely:
Sociodemographic Data sheet, socioeconomic scale, pattern of
substance abuse questionnaire, symptom check list- 90
(SCl – 90) and Norbcek Social Support Questionnaire (NSSQ).
Results: The main
results yielded by the study proved that,
a higher percentage of married was found among the addict
patients than those in control group, the percentage of the
manual work (workman) among the addict patients was higher than
the control group, the level of secondary education was higher
among the addict patients than in the control group, The high
social class was observed more frequent among the addict
patients, the oral administration was observed more frequently
than the other routes, tranquility was the first desired effect
for drug abuse, depression was the more frequent symptom among
the addict patients, and the addict patients had bad social
support compared to control group. Recommendation:
healthy productive activities should be provided for youth in
the community to keep them away from harmful stimuli.

Abstract:
Child adoption is a legal entity
based on which there would be a special relationship between the
adopted child and the adoptive parents. This phenomenon has a
long history throughout the history of law and has always been
cared for in various periods of time for different purposes.
This legal foundation has been recently accepted in western
countries laws in complete, incomplete, or simple forms with
different results and after some developments. In spite of
accepting this institution in Iran during the Sasanid dynasty
and its validity among the Zoroastrians, it was abolished
through the influence of Islam; however, due to individual and
social benefits, and the crucial need of the society to
establish justice and in order to protect the unprotected
children and orphans, it was revived under the title of
protecting unprotected children with certain legal requirements.
In comparison to Iran, child adoption has a long history in
other countries and it has different conditions and requirements
in various periods of time and in different law systems. With
regard to different perspectives and various methods, adopting a
child within a family will lead to the creation of some legal
relationships in law. Therefore, this paper aims to study child
adoptions rights in the laws of Iran and France.

Abstract:
Although women's achievements
are considered to prove their desirable conditions in western
societies, especially in the United States, women’s presence at
political elite level is much lower than men in that country.
Attention to the top elective offices in the United States
reveals a deep gender disparity: In 112th congress
(2011-2013), among 435 representatives, there are only 17 women
in Senate and 75 in the House. Considering the success of the
“quota system” in European, Latin American, partly African and
Asian countries, the author believes that using of this method
in the United States in the short term, help the women to be
more confident in their abilities and also, people feel the
positive effect of their presence and vote them more. On the
other hand, since according to the accomplished researches,
women have more inclination for peace, their more presence in
the congress, can be influential in interior and foreign
policies, and hence, in international relations. This article
surveys and analyzes the reasons, seeking to understand why in
the United States, with an established democracy, women’s
presence is lower than men at high political positions and
descriptive-analytical method is used to examine factors leading
to this lower presence. The factors are: political, economic,
and social-cultural.

The comparison between "ideal
kingship" in ancient and middle era
Zia Khazaei
Department of Political Science,
Zahedan branch, Islamic Azad University, Zahedan, Iran.
Abstract:
Political philosophy is part of
philosophy in general sense. A political theory by a philosopher
is affected by his philosophical attitude towards the universe,
the existence, creation structure, and finally cognition the
truth. Therefore, in order to understand the political
philosophy, at first the philosophical attitude of a philosopher
toward a tribe or nation must be allocated. Since in ancient
philosophy capturing does not tolerate possessing entire the
world so political philosophy is opposed to the policy based on
prepotency and sovereignty. Thus, formulating and developing a
desirable society is considered as a goal of political
philosophy and realization the utopia is not possible through
violence. So the nations and peoples who philosophically
contemplate always disagree with the policy based on the
prepotency and their political ideals were the basis for
criticizing the current policies and paved the way for the
opposition to the force and domination policy. Iran's ancient
civilization along with the philosophical contemplation composed
of political philosophy was the foundation of criticizing the
politics in the form of ideal kingship and Persian utopia and
continued through the end of the Sassanid dynasty and gradually
tended to weakness and decline by dominating Iranian element and
gradually lost its ideological and philosophical component so
that it turned to justifying the policy based on prepotency and
hegemony in middle era.

Abstract:
The synthesis of a new polyfunctional disazo reactive disperse
dye containing bis (sulphatoethylsulphone) /monochlorotriazine
reactive system is described.
The
structure of the synthesized dye was established and confirmed
by TLC, elemental analysis and spectral data (IR and 1H-NMR).The
dye has been applied to nylon 6 and silk fabrics at a variety of
pH.
Optimum dye exhaustion and
fixation were achieved at pH 8 and 100 °C.
The introduction of two temporarily
anionic sulphatoethylsulphone and monochlorotriazine reactive
groups into the reactive disperse dye molecule was found to
promote the fixation and the build up, as a result of the
combination between two different reactivity in the dye a
complementary behavior achieved to resist variations in dyeing
conditions. The results of dyeings on both substrates indicate
that the model polyfunctional disazo reactive disperse dye shows
a higher degree of exhaustion and fixation on silk than on nylon
6. All the dyed fabrics tested
displayed high light fastness and excellent fastness properties.

The Holiness of “Rooster” in
Mithraism
Mahin Ahbabi
PhD Student of
"ancient history", Tajikistan Academy of Sciences, Tajikistan
Abstract:
According to the myths, the
rooster was among the first birds, which was introduced to the
Iranians by Keyumars, and stayed with the human forever. Since
the beginning of domestication, and then at the peak time of the
Mithraism among the Aryans, the rooster had holiness, and
venerability. It was the partner of Sraosha Yazata, Mithra
Yazata, and the Sun, and helped them in repulsing the Satan,
demons, and elves. One can find its holiness and cooperation
with the Sun and Mithra, in the Greek and Iranian myths. In the
Zoroastrian religious books, rooster is one of the holy and
good-created creatures of Ahura Mazda. Therefore, among the
Iranian, Afghan, and Tajik people, the rooster, owned holiness.
Therefore, in the works discovered, in the settlements and
myths, one can find the relationship of the rooster with their
religion and rituals, because, in the past, the rooster’s vigil
and crow at dawns used to be like a warning or alert for the
Aryan people. With its crow, people used to get up in the
morning and started working, and it was known as the power of
gods. The holiness and venerability of the rooster, stayed among
the people after Islam as well.

Evaluation of capitalism process motivation mechanism in basis
of fiscal in Iran’s industrial Companies
Hakimi, Farhad
National University of Tajikistan
Email: Farhadhakimi650@yahoo.com
Abstract:
developing and developed countries constantly apply fiscal
policies in order to modify level, scheduling, type and
structure of various industries’ capital expenses. some fiscal
policies which are applied in this base would be such as
alteration in fiscal rates, alteration in deductions’
depreciation rate, endowing different exemption, fiscal
discount, etc. regarding the point that Iran Islamic republic
has reformed fiscal rules in 2001,so present research put an
effort to reform the recent rule which have been designed with
the purpose of capital rate growth. this research has been
accomplished as a case study on observation of capital process
stimulus mechanism by Iran industrial companies ‘s fiscal that
necessary financial information concluded from 2006-2009 years
and using F test and Hausman test, results indicate that new
rule hasn’t key role in capital rate regardless of
pre-conditions of rule reformation and fiscal exemption and
other factors such as bank profit rate, housing enhancing rate,
etc would be more effective. the main purpose of this research
would be observation of companies ‘s fiscal rates on capital
behavior in fixed budget of companies in Tehran’s priced paper
stock which is as the Iran ‘s industry representative, also this
hypothesis would be mentioned here that capital in fixed budget
has significant role in theory of fluctuations and economical
growth and also in designing the fiscal policies.

Abstract:
Understanding of the seed germination response of cultivated
genotypes to low and high temperature is important
in agronomical. Those genotypes
that germinate in lower temperatures could be useful in
temperate areas where temperature is low in germination stage
whereas the genotypes tolerant to high temperatures could be
sown in the areas with high temperature. Therefore, this
experiment was conducted to study of the seed germination
characteristics to temperature. In this experiment we used 9
genotypes of safflower crop with 7 fixed temperatures (50C
, 150C , 200C , 250C , 300C
, 320C and 360C ) as factorial experiment
in the growth chamber. The results showed that the effect of
genotype, temperature and their interactions on germination
characteristics were significant and significant reductions in
the germination of safflower at temperature less than 50C
and upper than 300C . The base (Tb),
optimum (TO) and maximum (TC) temperature
for germination safflower were obtained 3, 28 and 38
respectively.

Abstract:
Priming is one of the seed enhancement methods that might be
resulted in increased seed performance (germination and
emergence), seedling growth and plant yield under stress
conditions, such as salinity, temperature and drought stress. In
order to evaluate the effect of growth hormones on morphology
characteristics and
essential oil of
basil under drought stress
condition, an experiment was conducted at plant research center
in Islamic Azad
University of Gorgan Branch, Iran, in 2011 year. Experiment was factorial conducted based on CRBD design with 3
replicate in greenhouse. Treatments were include 4 levels
priming by growth hormones (control, cytokinin (3%), GA3 (200
ppm) and combinations of hormones for 12 h) and 4 levels of
drought stress (D1=100, D2=80, D3=60 and D4=40 percentage of
field capacity). Results
analysis of variance showed that drought stress had negative significant effects on
emergence percentage, morphology characteristics, 1000-seed
weight and yield of essential oil,
chlorophyll contents and
antioxidant enzyme (APX, CAT, GR, SOD and POD), but reduced
priming by growth hormones these negative effects. Results of
comparing means showed that priming by combinations of hormones
had positive significant effects on study factors compared to
other seed priming treatments (cytokinin and GA3).

Abstract:
Aim:
To compare between the use of biological fibrin adhesive and
the current method of attaching conjunctivo-limbal autograft
with simple suturing during primary
pterygium surgery. Patients & methods: Twenty-nine
patients with thirty primary pterygia
had pterygium excision using
conjunctivolimbal
autograft transplantation.
They were classified into two groups regarding the method by
which the transplanted
conjunctivolimbal
autograft was fixed
as follows: Group I: Simple suturing
was done for 15 eyes. Group II: Fibrin glue was done for 15
eyes.
Results:
Marked drop in tear production ( around 10 mm) was reported in
both groups and there was non significant statistical
difference between both groups as regards the value of
Schirmer's test (p-value >
0.05).
Re-epithelialization of the corneal defect was complete in all
cases of both groups by the end of the second postoperative
week.
There was marked reduction in the mean duration of surgery in
group II (19.7±5.2minutes) in comparison to 39.7 ±
3.9 minutes in group I.
Conclusion:
Fibrin glue is easy, safe and effective in fixing
conjunctivolimbal autograft during primary pterygium excision.
It reduces surgical time and is associated was less
complications than
simple
suturing of the graft.

An
analysis of the reasons of Abu Muslim Khorasani’s animosity
towards Abbasid veteran Propagandists

aa_abbasi_z@yahoo.com
Abstract:
One of the Abu Muslim
Khorasani’s strange actions was to kill famous and veteran
Abbasid Propagandists. Abu Muslim himself was called as the
Propagandist and was the leader of Abbasid revolt in Khorasan at
the time of its appearance. He was so much clever and took
action with organized plans. In this article we intend to
analyze and clarify Abu Muslim’s plan and purposes of killing
Propagandists who were more experienced than him in Abbasid
propaganda and revolt. Abbasid veteran Propagandists did not
consider Abu Muslim important even at the pinnacle of his honor
and glory, because during his adolescence he was a slave who was
bought by Abbasid propagandists and bestowed unto Abbasid imam
and this caused their being ruined by Abu Muslim when the leader
of black garments reached honor and gained power. Famous and old
individuals such as Lahiz Tamimi,
Qahtabah
Ibn Shabib Tai, Abu Salamah
Khalal and Sulayman Ibn Kathir Khuzai
were ruined by Abu
Muslim’s plan.

development in third world countries where farmers directly
connected with market, buyers, customers and metrological
department to get information regarding weather and price.
Information communication technology has also increased the
income of farmers in different countries. Now there is need to
provide facilities to farmers and introduce technology in rural
areas where farmers are unaware and they do not have knowledge
and skills regarding this technology. It was also indicated by
different research that this technology has increased the
product of agriculture by adopt information and communication
technology tools in agriculture farming. However, farmers are
facing major problems and challenges including poor agricultural
practices inadequacies in information delivery reconciliation of
records among farmers, government and traders similarly lack of
information on best practices to farmers.

Hangouts in Iranian
neighborhoods
Vahid Bali Chalandar, Nahid
Shangal Nia
Abstract:
Spread of ties and familiarity
of people with new elements led to the emergence of special
thoughts. This
process resulted in the emergence of intellectuals
and their efforts to find a place for meeting and discussing
different issues was followed by the
establishment of various
intellectual hangouts. Hangouts may be assumed independent of
location and the location ascribed to the hangout. In fact, it
is not the hangout talks that are attributed to a specific
location but a specific place can be attributed to a particular
group. When there is no interest or meaning as well as it is in
the community, mental conditions of people gathered in a place
inevitably pulls them toward
accepting each other. One of the major tasks of humans in cities
is to understand leisure time and how to use it. In addition to
human growth and excellence, leisure time has an undeniable role
in improving social relations in a society. General use of urban
spaces is to create a place for relaxation, entertainment,
jaunt, communication, socialization, and traffic. Hangout is a
new issue and event and belongs to the modern world; worlds in
which free individuals are present in free gatherings and take
action to socialize without any specific plan. These components
build a new social life. Outdoor urban spaces and public
gathering places for social communications are considered as
hangouts in the present paper.

Abstract:
Mobile ad hoc networks (MANETs) are self-configured nodes that
are connected to each other without any static infra-structure
like conventional wired networks. This attractive technology
offers many interesting applications in different areas such as
rescue operations, and army war zones. However, MANETs are
exposed to many security challenges. The conventional security
solutions for wired or wireless networks are ineffective and
inefficient due to cooperative nature of MANETs. A significant
amount of research is found in the literature to address these
security challenges. In this paper, we have reviewed many
proposed security solutions. We have proposed modified security
architecture to address some security issues. Then we have used
formal methods to define the security architecture using Z
notation. Finally we have analyzed and verified these
specifications using Z/Eves toolset.

RATIONAL VARIABILITY OF ALL EMPTY SPACE BY PRIME NUMBERS
(The new Mathematics of
Primordial 1:3 and “Chan” function of prime numbers)
Part 1: The Curved “Chan”
Function of Prime numbers
Vinoo Cameron MD,
Hope Research, Athens, Wisconsin,
USA.
E Mail:
Hope9900@frontier.Com
ABSTRACT:
The author has written
this manuscript exclusively for Dr Sophia Wang of JMR and Dr
Hong Ma, editor of JAS for their brilliant
humility and creative understanding of science, for
understanding function over form. All of this mathematics is due
the exclusive grace of my personal Lord Jesus Christ.
This paragraph is absolute, in that we all perform our best by
inspiration and not by intellect, which itself is relative.
Mathematics is absolute.
The author wishes to make
it clear that there is absolute proof by theorem in this
manuscript to tie the modulation of Prime numbers exclusively to
the proportions 5:6:7, with the proportion 6 being the
equalization factor representing the half-line of the variable
coordinates of empty space. Without doubt the proportion prime
19 with its1:3 expression in empty space and inverse
19 (for trigonometry at 1:3), is
the actual measuring compass of the entire mathematical
continuum that unifies mathematics. The published papers are
exact in delineating the curved function of Prime numbers and
the half line that modulates this function. Likewise we have a
superior sieve for prime numbers at 6 that however is not
relevant here, as we are here to prove the new discovery of
“Chan Point”, and Modulation of the prime numbers curved
function (© Chan Function.
Section 11, will deal with
the unification of prime numbers to a corrected new trigonometry
and the correct mathematical
value
(3.14159292035), which is long overdue due in mathematics.
Current mathematics has not yet proven the correct Pi value by
mathematics.
Caution: since the mathematics
is curved, kindly, if you seek to understand it, take the curves
very slowly. The proof of the 5:6:7 is absolute here, and is
“Ipso Facto”.

Developing and Validating
Proposed Occupational Risk Management Standards at Critical Care
Units

Magda_elmolla@yahoo.com
Abstract:
Risk management for health care
institution is not a new socially and/or legally ordained
program. A pro active risk management (RM) is an approach to
identify and eliminate or minimize hazards. So risk management
demand is a proactive rather than reactive strategy. Therefore,
hospitals needs to develop risk management standards to provide
guidelines for managing risks, protect patients, health care
providers and organization’s acids. A critical care unit is a
high- technology environment. However, the critical care nurse
needs not only to be aware of what benefits the technology holds
for patients, but also what adverse effects. The aim of this
study was to develop and validate risk management standards for
critical care unit, El- Manial University hospital. A
methodological design was carried out on a sample of seventy
nurses and thirty physicians at critical care unit El- Manial
University hospital; data was collected over a period three
months. A risk assessment questioner tool was developed by the
researcher. It consists of two parts: (1) socio-demographic data
and (2) risk management standards (30 items) it covered 5 major
occupational risk factors. Expert
opinionnaire
sheet about content validity and face validity of the proposed
RM standards was undertaken. The study findings related to
occupational risks hazards were occupational risks at low level
in biological, psychological and physical risks(50%,48% and 47%
respectively), while at moderate level in environmental and
chemical risks(43% and 48% respectively). They exposed to air
born and blood born in moderate level which should be managed by
hospital within a week. Also, a statistical significant
difference between the psychological, environmental and chemical
risk was evident at P< 0.0564, also between years of
experience and exposure to risk. The study suggested RM
standards should be used by the critical care unit; as well
these standards should be reviewed, revised and updated
periodically every three years. Also, establishment of RM units
within the critical care unit is recommended. In addition,
applying of RM standards should be encouraged and rewarded
encourage notification about risks.

Abstract:
Nursing is one of the most stressful careers in the world
and this stress
affecting most aspects of nurses life. However, the effect of
occupational stressors on their mental
health status is not clear yet, so the aim of this study was to
evaluate relationship between occupational stressors and mental
health status among university hospital nurses.
Methods:
In this analytical
cross – sectional, study 146 nurses of teaching hospital of
Ahwaz University were enrolled. The
participants filled three questionnaires of personal
characteristics, nursing stress scale (NSS) and general health
questionnaire (GHQ28) and the relation between occupational
stressors and mental health of samples was investigated.
Results:
Of those nurses who responded,
136 (93.7%) were female and 9 (6.3%) were male. The mean age of
participants in the study was 38±15 years. Duration of
employment was 14±12 years. GHQ-28 scores and NSS scores had a
positive correlation with each other (P<0.001, r=0.329).Conclusion:
According to present study, positive association between
occupational stressors and mental health status of nurses is
existed, and because of the importance of their mental health in
their nursing care quality, it seems paying attention to nurse
occupational stressor and their mental health in level of
prevention is essential.

Abstract:
Background: Joubert Syndrome (JS) is a rare genetic
developmental disorder, first identified in 1969. In patients
with JS, certain regions of the brain (mainly cerebellar vermis
and brainstem) are underdeveloped or malformed. This can lead
to impaired attention, visual, spatial, motor, language and
social functional skills. JS is characterized by a host of
features, many of which do not occur in every patient. Aim of
the study: To spotlight and increase awareness of clinical
profile and neuroimaging findings of children with Joubert
syndrome. Methods: This is a retrospective case series
study of patients with JS who attended the Pediatric Neurology
Clinic in Aladan and Alfarawanya Hospitals in Kuwait, from
September 2007 to September 2012. Clinical and radiological data
were obtained from the patient medical records. Results:
Cerebellar vermis hypoplasia/aplasia and apnea were present in
all patients, polydactyl in 3 of 16; renal problems with cysts
in 5 patients and 11 of 16 had abnormal electroretinograms
(ERGs). Blood investigations of organic acids, amino acids and
very-long-chain fatty acid, were normal in the all the nine
patients. Conclusion: JS is a rare genetic brain
malformation with association of retinal dystrophy and renal
abnormalities. The retinal dystrophy may be progressive. The
prognosis of patients depends mainly on the degree of brain
malformation.

Tissue Extract Fluid Cytokine
Levels as Markers for Wound Vitality: An Experimental
Comparative study
Ahmed H. Rizk MD, Mohamed
El-Shishtawy MD, Adel F. Al-Kholy MD*
Departments of Forensic &
Clinical Toxicology & Medical Biochemistry*,
Faculty of Medicine, Benha University
Abstract:
Objectives: To experimentally evaluate the ability of
estimation of tissue extract levels of interleukin (IL)-1β,
tumor necrosis factor (TNF)-α and IL-6 for differentiation
between antemortem (AM) and postmortem (PM) wounds and for rough
determination of time lapsed since death till wound inflection.
Material & Methods: The study comprised 20 normal healthy
growing adult male albino rats. Four skin biopsies were obtained
from the back of each animal; one AM and 3 PM. Each PM biopsy
was obtained from the edge of new wound inflected at 30-min
(PM1), 60-min (PM2) and 6 hours (PM3) after death. The subcutis
of skin specimens was removed and skin samples were homogenized
and tissue extract fluid (TEF) was used for ELISA estimation of
IL-1β, TNF-α and IL-6 levels. Results: Mean AM specimens
TEF levels of IL-1β and TNF-α were significantly higher compared
to their levels estimated in the three PM specimens with
significantly higher levels in PM1 and PM3 specimens compared to
PM2 specimens. Mean PM2 specimens TEF levels of IL-6 were
significantly higher compared to AM, PM1 and PM3 specimens with
significantly higher levels in AM specimens compared to PM3
specimens. There was a positive significant correlation between
TEF levels of IL-1β and TNF-α with wound vitality. While TEF
levels of IL-6 showed a positive significant correlation with
time lapsed between death and wound inflection. Using receiver
operating characteristic (ROC) curve analysis, elevated TEF
level of IL-1β showed significantly high sensitivity for
identification of wound inflected since ≤60 minutes PM with area
under curve (AUC=0.186, p=0.035) compared versus the null
hypothesis, while TNF-α and IL-6 showed non-significant
difference. Conclusion: Estimation of TEF levels of IL-1β, TNF-α
and IL-6 could differentiate between wounds inflected while
animal was alive and PM wound. However, estimation TEF level of
IL-1β works better for such differentiation and could determine
wound inflected within 60 minutes PM with high sensitivity.

maximal, minimal, and presystolic volumes measured according to
biplane area length method and LA mechanical function parameters
calculated. Results: Pd and inter atrial
electromechanical delay were higher in type 1 diabetic children
than control (P<0.001). LA active emptying volume and LA
emptying fraction were increased in patients than control (P<0.001).
Interatrial electromechanical delay was negatively correlated
with early diastolic trans-mitral velocity, left ventricular end
diastolic diameter, and presystolic atrial velocity and
positively correlated with the average systolic velocity of
mitral annuli (P=0.025, P=0.05, P=0.005 and p=
0.017, respectively). The intra-atrial delay was negatively
correlated with maximum LA velocity, minimum atrial velocity
and total LA emptying volume (P=0.006, p=0.036 . p=0.038,
respectively). Duration of illness and DM type 1 were
independent predictors of interatrial electromechanical delay by
multivariate analysis (p=0.001 and 0.0001).
Conclusion: children with DM-1 demonstrated LV and RV
diastolic dysfunction, increased Pd and inter atrial
electromechanical delay which predispose them to develop AF.
LA compensates for LV diastolic dysfunction by increased the LA
active emptying volume.

Abstract :
Despite numerous
pathological studies, the origins of retinoblastomas are still
controversial .Aim: of this study was to clarify
which factors are expressed in retinoblastoma cells and to give
insights into the cell origin of retinoblastomas. Materials
and methods: eleven patients with retinoblastoma (7 males &
4 females) patients were diagnosed in the Eye tumor Unit,
Ophthalmic Department, Ain Shams University; they were divided
into 5 groups according to
International Classification of Retinoblastoma. Sections
were examined histopathologically and immunostained by mouse
monoclonal antibodies against Nestin, GFAP and NF for
identification of undifferentiated stem cells, mature glial
cells and mature neurons. Results: histopathologic
findings in the examined samples revealed that 6 cases were
poorly differentiated and 5 cases were well differentiated. Both
Nestin and GFAP expressions were detected in the stromal cells
not in the tumor cells, possibly representing muller cells and
reactive stromal astrocytes respectively,
in contrast, in all samples neurofilaments were expressed in the
cytoplasm of the most retinoblastoma cells. In conclusion,
the results of this study support that retinoblastomas are
derived from mature neural cells and not originate from cancer
stem cell(s).

Abstract:
In this
paper, a Kalman filter for fractional order singular systems has
been proposed. To design the Kalman filter, the fractional order
singular system is decomposed into two sub-systems by using
several transformations. The first sub-system is a dynamic
system with fractional order non-singular state equations and
the second sub-system is a static system in which the output is
a combination of fractional derivatives of its input. Then, the
Kalman filter has been elaborated for the system with an index 1
and 2. In the case of index 2, the identification method should
be used due to the existence of color noise. At the end, two
examples are used to demonstrate efficiency of the proposed
method.

Abstract:
This paper aims to quantify the
uncertainty associated with the methods commonly used for
calculating straining action values (mainly the bending moments)
of retaining structures sections supporting cemented sand. The
study is concerned with diaphragm wall supporting three kinds of
cemented sand currently founded in the nature (Sand
cemented with calcium carbonate, calcium sulphate and clay). A
probabilistic approach based on Monte Carlo simulation
technique is used to determine the increase in bending moment
values and its probability of occurrence, due to change in soil
characteristics from dry to soaked state as a result of exposure
to water. This paper is useful in that it enables the designer
to calculate the increase in straining action (Bending
Moment)values relevant to the risk taken and its probability of
occurrence, as a result the designer can calculate an economical
retaining structures sections.

Abstract:
Post lumber puncture headache (PLPH) has been a problem for
patients, following dural puncture. Headache after lumbar
puncture is a common occurrence (32%) and carries a considerable
morbidity, with symptoms lasting for several days, at times
severe enough to immobilize the patient. If untreated, it can
result in serious complications such as subdural haematoma and
seizures, which could be fatal. The accompanying symptoms are
usually nausea, vomiting and neck stiffness. Other nonspecific
symptoms may occur such as ocular complaints as photophobia and
diplopia, and auditory complaints like tinnitus and hyperacusis.
PLPH typically manifests as a postural, frontal, front temporal,
or occipital headache, worsened by ambulation and improved by
assuming the lateral position, occurring within 48 hours after
dural puncture. Aim : The aim of this study was to
examine the effect of pre-discharge instructions on prevention
of headache and its associated symptoms among patients
undergoing diagnostic lumber puncture Subjects and Methods:
Design:
A quasi experimental design
was used. Setting: This study was conducted at
lumber puncture unit at hematology and hereditary department
(medicine 12) affiliated to Ain Shams University Hospital.
Sample:
A purposive sample included
60 patients undergoing to diagnostic LP.
Tools for data
collection: The
patient Lumber puncture interview questionnaire (Pre and Post
Lumber puncture procedure), Headache Diary (Post Lumber puncture
procedure throughout seven days), Headache Impact Test™
questionnaire (HIT-6TM) (Version 1.1) Post lumber puncture
procedure and LP patients perception sheet. Results:
The
intensity of the headache
among the control group was higher compared to the study group
with highly statistical significant difference from day two to
seven day.
Also, there was no statistically significant difference
regarding total knowledge regarding PLPH and associated symptoms
pre- instructions implementation, while there was an improvement
with a highly statistically significant difference post
instructions implementation.
The impact of the headache on the
control group higher than the study group with a highly
significant difference between them regarding daily living
activities.
There was a significant difference between the personal
characteristics and intensity of the headache between study and
control group.
Conclusions: The
implementation of pre discharge LP instructions was effective in
reducing the intensity of the PLPH and occurrence of associated
symptoms. The pre discharge instructions had a positive effect
in increasing the level of perceptions in the study group
patients. Recommendations: It was recommended to use the
Arabic Instructions in outpatients for patients undergoing
lumber puncture and further studies should be carried out on a
large number of subjects for evidence of results and
generalization. Also, further study
is recommended to
evaluate the association between post lumber puncture headache
and its associated factors.

Abstract:
The purpose of this paper is to
examine the impact of empowerment on employee's performance in
automobile parts manufacturing industry (APMI) in Iran.In this
research, the factors and the characteristics of the
psychological empowerment model of employees in Iran's APMI have
been identified and prioritized appropriately and relevantly
with the empowerment model in the local environment based on
current literature and then using factor analysis statistical
procedure and structural equations technique, the ultimate
combination of factors has been analyzed in the local
empowerment model framework aiming at the improvement of the
performance of employees' at APMI selected from 56,052 employees
working in 1,933 APMI companies in Iran. Statistics society
consists of the experts of human resources (HR) and
organizational behavior of especially university staff and some
of the specialists in large companies APMI. The sample size
provided based on "Cohan- Morgan- Korjsay" is 382 persons which
has been determined with descriptive methods. For data analyzing
we used with Delphi method to identify and explore the local
variables of psychological empowerment and performance of
statistical population to be introduced to answer the first and
second research questions. Also, to collect data regarding the
third and fourth research questions, multi-phase cluster
sampling was utilized. Then to evaluate the gathered variables
and to identify the relationship between psychological
empowerment and performance of employees, Structural Equations
relations, LISREL Software was utilized so as to obtain the
optimal model between these variables. To examine the
relationship between the characteristics of statistical
community and their empowerment level, ANOVA was employed.
The Cronbach’s alpha for
this study was 0.89.. The
results obtained from the analysis of findings indicate the
fitness of model and it can predict and estimate up to 92% of
alterations of psychological empowerment on performance. Given
that the set of linear equations in the route diagram fits into
observed data, it can be concluded that the existence of causal
model is significant and this model is an appropriate model to
answer the research question. In fact, investigating the
subordinate questions of research, it can be analyzed that the
model has a foreign existence. With regard to the results
obtained from the research questions and the relationship
between independent and dependent variables, it can be stated
that the competence and effectiveness traits have the most
positive and increasing impact on APMI employee’s performance,
and on the other side, the trait of self-determination has the
least impact on empowerment.
Moreover, on the basis of
the results of the statistical tests in Structural Equations
Model, it can be concluded that the existence of relationship
between the dimensions of employees’ psychological empowerment
and their performance (attitudinal behavioral) is confirmed and
it is the research model and the optimal model of psychological
empowerment that leads to improvement and performance promotion
of employees in Iran’s APMI.

Abstract:
In the Northern Iraq, the Jurassic oil shales are widely
distributed. The studied samples were collected from Sehkanyian,
Sargelu and Naokelekan formations in Banik area, about 25 km due
NE of Zakho town, Duhok Governorate, North Iraq. The hydrocarbon
potentiality parameters, including type and amount of bitumen
and kerogen, and thermal maturity of 72 samples as well as two
oil samples were assessed by using Rock-Eval/TOC pyrolysis and
GC/GCMS techniques. In general, Sargelu Formation samples have
PI values below 0.1 and Tmax values varying between 437 and 449,
suggesting immature to early mature stage of thermal maturity of
oil. They can be considered as good to excellent source, where
TOC content ranges from 0.06 to 28.57 with an average of 4.69%.
The Naokelekan Formation samples can also be considered as an
excellent source rock with TOC content ranges from 5.39% to
25.55%, averaging 17.77%, while the Sehkanyian Formation has no
potential (TOC below 0.09%). The samples of Sargelu and
Naokelekan formations contain both kerogen types I and II
indicating marine organic matter mainly derived from algae and
phytoplanktonic organisms proposing typical oil source kerogen.
The extracted bitumen samples from Sargelu Formation show
diagnostic ratios of Pr/Ph, Pr/nC17 and Ph/nC18 for generation
of oil at an early thermal maturity stage. The low Pr/Ph ratio
of the analyzed two oil samples from Jeribe and Sargelu
formations together with the low Pr/n-C17 and Ph/n-C18 suggest
that the oils was generated from a source rock containing mainly
marine organic matter deposited under reducing conditions.

Abstract:
Today, achievements in science and technology in different
societies has taken a non controllable and explosive trend such
that human being witnesses discovery and invention of
instruments, devices, structures and processes without which it
is not possible to solve organizational problems. It means that
people force to equip their knowledge with new and up-to-dated
technologies and knowledge in order to face daily problems and
solve them. It is also the case in higher education. Considering
that three skills are important in management (scientific,
technical and artistic), it is necessary to reinforce all of
them in educational settings with cooperation of higher
educational sponsors so that all professors can benefit from
them and reinforce these skills. In this regard, strategies have
been presented in conclusion and it is hoped that they will be
used effectively.

Abstract:
The purpose of the present study
was to assess the antioxidant role of wheat germ oil (WGO) in
clozapine-induced oxidative stress and biochemical changes in
liver of male albino rats. Clozapine (CLZ) was given orally and
daily for 6 weeks at a dose of 27.0 mg/kg b. wt rat. WGO was
given orally 3 times/week for 4 weeks at the dose level of 900
mg/kg b. wt rat . In all groups ,CLZ and WGO was given directly
into the stomach using a gastric tube , At the end of the
experiment , the liver was extirpated in all of the animals .
Tissue homogenates prepared from the tissue specimens were
analyzed for malondialdehyde (MDA) levels ,superoxide dismutase
(SOD) activities and liver glutathione content (GSH). The
results: showed that the enzyme activities such as alanine
aminotransferase (ALT), aspartate aminotransferas (AST),
alkaline phosphatase (ALP) and were significantly increased in
rats administrated only by CLZ . In addition, CLZ caused a
significant increase in the activities of superoxide dismutase
(SOD), liver glutathione content (GSH)
and
malondialdhyde level in liver
tissue. In conclusion: It was determined that CLZ led to
adverse alterations in the majority of the oxidative stress
markers and biochemical parameters. Wheat germ oil
supplementation caused significant improvement in different
biochemical parameters of all rat groups.

Abstract: Revenue
Malmquist Index explains change of Revenue productivity of
Decision Making Units (DMUs) in two periods. The Trade Offs
approach is an advanced tool for the improvement of the
discrimination of Data Envelopment Analysis (DEA) models. They
used CRS models in DEA for computing this index, since the
convexity assumption is strong condition for computing, so for
solving this problem in this paper we use Free Disposal Hull (FDH)
models in DEA for computing Meta Revenue Malmquist Index. Also
In this paper Revenue Malmquist Index is evaluated considering
in fact that relative importance of inputs and outputs in
different periods are different. In the papers concerning
Revenue Mamlquist Index this fact is not considered, which is
very important from managerial point of you.

Abstract:
The antibiotic properties of Sennaalexandarina (L.)
leaves extracts were studied against five bacteria, two molds
and yeast by using the disc diffusion method. Acetone extracts
(12mm zone diameter of inhibition, MIC 200 μg/mL and MBC 300 μg/mL)
demonstrated the highest activity followed by dichloromethane (8
mm zone diameter of inhibition, MIC 300 μg/mL and MBC 400 μg/mL),
methane (7 mm zone diameter of inhibition, MIC 400 μg/mL and MBC
400 μg/mL) and hexane (6 mmzone diameter of inhibition, MIC 800
μg/mL and MBC 1000 μg/mL). Water extracts demonstrated the least
activity against the test bacteria and fungi (4 mm zone diameter
of inhibition, MIC 800 μg/mL and MBC 800 μg/mL).
Phytotoconstituents presentation included Saponins, Tannins,
Alkaloids and Flavonoids. S. obtusifolia(L) can be used
to source antibiotic substances.

Abstract:
Thiamin (vitamin B1)
was the first
vitamin to be
discovered. Under
most circumstances, there is
few chance of thiamin deficiency
for mono gastric animals, including humans, when diets
contain ample quantities of
whole cereal grains or starchy roots. However,
many thiamin
antagonists in the
food supply, and sensitivity
of the
vitamin to processing, can lead
to deficiency.
Thiamin deficiency in
humans has been a problem mostly in
Asian countries, where
highly milled
rice is consumed, therefore laminating the thiamin-rich bran
fraction of the grain. For
years, it
was accepted that ruminants didn't
require vitamin
B supplementation thus
of enough rumen micro
flora synthesis.
Intensification of
ruminant feeding,
involving
high-concentrate diets,
and management
systems by increased
levels of
production have resulted
in nervous
disorders which are
responsive to
thiamin
supplementation.

Abstract:
The inappropriate political
relations with neighbours and the cultural and historical
similarities have made Armenia as a suitable market for export
of agricultural products from Iran. The aim of this study is to
review the current situation of the export of agricultural
products from Iran to Armenia, between 1999-2010 and the factors
which have impact on it. However, there is a need to estimate
the actual exchange rate during this specific period beforehand.
Therefore, the actual exchange rate between 1976-2010 has been
estimated through the VECM model and data based on the basic
economic variables. Ultimately, the trading data between Iran
and Armenia during 1999-2010 has been used in order to specify
the effective factors on the export of agricultural products to
VAR. According to the result, the variables of Gross Domestic
Product (GDP) in Armenia and the actual exchange rate have
positive effect on the export. Therefore, we suggest strategy of
the increase in the Nominal exchange rate to raise it up to the
actual exchange rate in addition to investing in Armenia, to
increase the export.

Abstract:Carbohydrates
(CHO) are the major source of energy for rumen microorganism and
the single excessively component of a dairy cow’s diet. They
represent the major component of net energy for astound of keep
and milk production. Those are as important to the ruminant
animal as they are to non-ruminants, thus they provide the
glucose necessary for the adequate function of cells. However,
in the ruminant, ruminal fermentation transforms most of the
cell wall polysaccharides and all of the intracellular
carbohydrates present in the forage into short-chain volatile
fatty acids that are then absorbed by the rumen epithelium.
Plant tissues contain about 75% carbohydrates, providing the
primary sources of energy for both the rumen organisms and the
host animal. The carbohydrates found in plant tissues are
primarily polysaccharides, cellulose, hemicellulose, pectin,
fructan and starches, with slight amounts of other compounds.
Cellulose is the most abundant. However, grains are widely used
in diets used in intensive production systems with highly
productive animals, providing an appreciable amount of starch
for ruminal and intestinal digestion. The purpose of this review
is to scrutinize the present science on starch digestion in the
ruminant, as well as glucose metabolism in the rumen, post-ruminal
absorption of starch and glucose requirements of the ruminant.

Abstract: NATO after
cold war decided to develop its relationship with the states in
central Asian and Caucuses. The NATO viewed the region as
strategically significant for the West. At the same time, there
were several other reasons, which motivated the NATO to expand
its activities in the region. The views in Russia are
drastically different depending on the type and level of
relations with NATO. Some believe NATO a threat and some talk
about the necessity of membership in NATO. In general, Russia
considers NATO activities posed a threat as it was during cold
war period. In other hand, some of NATO policies are to pass the
red line of Russian security such as its expansion toward east
and acceptance of some countries.

Abstract:
More than 20 years after the discovery of the HCV, it is now
well established that HCV is of global importance affecting all
countries, leading to a major global health problem that
requires widespread active interventions for its prevention and
control. Chronic hepatitis C was linked to the development of
cirrhosis and hepatocellular carcinoma (HCC) in many areas of
the world. WHO reported that Egypt has
the highest prevalence
(22%) in
the world which explained by
the past practice of parenteral therapy for schistosomiasis. T
cells that produce IL-17 have recently been identified as a
third distinct subset of effector T cells, and emerging data
implicate Th17 cells as important in the pathogenesis of chronic
hepatitis C infection by regulating innate and adaptive
immunity, including autoimmunity
.So the present study was conducted to
determine the role of IL-17, with its potent pro-inflammatory
properties, among chronic hepatitis C cases with or without
cirrhosis and HCC aimed at future immune-therapy. The study was
conducted on 60 subjects with chronic hepatitis C infection
before starting antiviral therapy; 20 chronic hepatitis C, 20
cirrhotic patients and 20 HCC HCV positive as well as 10 healthy
subjects negative for HCV, HBV and HIV served as controls. IL-17
was quantitated after mitogen stimulated whole peripheral venous
blood by commercial enzyme linked immunosorbant assay ( ELISA
).Our results demonstrated a significant increase in
serum levels of IL-17 among cirrhotic and HCC patients infected
with HCV. While in chronic hepatitis C virus cases ,elevated
IL-17 values were non significant compared to controls.
We can conclude that IL-17 may play an important role in HCV
immunopathogenesis. It might be used as an indicator for
cirrhosis and HCC as it
promotes tumor growth by facilitating angiogenesis in tumor
microenvironment. Also, its therapeutic application needs to be
furtherly evaluated by in vivo studies in experimental
animals aiming at future immunotherapy.

companies in some countries and its comparison with some results
of carried out investigations in Iran and examines the
performance of privatization in companies with state ownership.
To do this, results of the study will be provided and then
compared in terms of changes in profitability, operational
efficiency, output, dividend and financial leverage. Then causes
of the changes will be stated. The results show that
privatization will aid the improvement of companies'
performances in many countries, industries and in competitive
media. Privatization causes increase in profitability,
efficiency, return, dividend and decrease in financial leverage.

Biochemistry, Cairo University
drsayed@gmail.com
Abstract: Background:
Renalase is a novel protein produced by the kidneys,
participating in the metabolism of circulating catecholamines.
Patients with end-stage renal disease have a significant
renalase deficiency, which could be a pathophysiologic mechanism
partially explaining high prevalence of hypertension in patients
with end-stage renal disease. The aim of the current study is to
assess possible relationship of renalase gene polymorphism with
hypertension in patients with end-stage renal disease.
Patients and methods: 139 patients on chronic hemodialysis
were recruited in this study. RS2576178 and RS10887800 was
genotyped using polymerase chain reaction. Patients were
subgrouped into hypertensive and non-hypertensive patients.
Allele and genotype frequencies were compared in both groups. In
addition fifty healthy subjects were enrolled as a control group
and subjected to the same genotyping.Results: Analyzing
genotype and allele frequency of RS2576178 renalase polymorphism
revealed that the difference between both patient groups was not
statistically significant. The slightly higher prevalence of G
allele in hypertensive group was also not statistically
significant.Analyzing genotype and allele frequency of R10887800
renalase polymorphism revealed no difference in frequency of GG
genotype. The prevalence of G allele was similar in both groups.
Analyzing allele frequency of RS2576178 showed a higher
frequency of G allele in ESRD group compared to healthy control.
Carrier state of G allele was associated with 7.2 times higher
risk of developing ESRD (OR=7.188; 95% CI: 3.5-14.7). Analyzing
allele frequency of RS10887800 showed a higher prevalence of G
allele in ESRD group compared to healthy control. Carrier state
of G allele was associated with 12.3 times higher risk of
developing ESRD (OR=12.3; 95% CI: 5.6-27.1). Conclusion: Unlike previous
reports of association of RS2576178 and RS10887800 polymorphisms
with developing hypertension in patients with ESRD, the present
study does not support a significant association in our
population. We rather suggest an association of these
polymorphisms with end stage renal disease.

Abstract:
This research has been done with
the purpose of investigating the effect of personality factors
(conscientiousness, trait anger), job factors (skill variety,
feedback) and organizational factors (distributive justice,
organizational constraints) on employees’ counterproductive work
behavior (CWB) and the moderating role of job burnout and work
engagement. To do this research, some 185 individuals working in
an Iranian Gas Transmission Operational Area have been randomly
selected and the questionnaire has been filled out by them. The
research model has been measured and performed by using
structural equation modeling (SEM) analyses. The results of SEM
showed that employees’ CWB have been strictly based on their job
burnout. On the other hand, employees’ job burnout has been
influenced by several elements such as skill variety, trait
anger and organizational factors. Moreover, the research has
shown that the employees’ engagement has not been affecting
their counterproductive behavior; rather it is affected by their
skills variety and conscientiousness. But, we found that there
is no meaningful relationship among trait anger, distributive
justice and organizational constraints with the employees’
engagement.

Arabia
afafageha@yahoo.com
Abstract:
The Lower Carboniferous Um Bogma Formation in west-central
Sinai, Egypt displays extensive and pervasive dolomitization.
Organic materials especially the carbonaceous matter was found
to play an important role in the
distribution
of the
radionuclides within soils
and sedimentary rocks.
The Um Bogma Formation is the more important formation than the
others as it hosts most of the radioactive anomalies.
Ten samples were collected from carbonaceous fossil wood trunks
and fragments embedded in siltstone and shales of early
Carboniferous age. These samples were studied by
X'Pert diffractometer for
the mineral and chemical composition. The most important
minerals in the samples are Goethite (Iron Oxide Hydroxide),
Graphite (Carbon), Quartz (SiO2), and Kaolinite (Aluminum
Silicate Hydroxide). The samples were also analyzed for
concentrations
(Bq/kg)
of 238U, 232Th series and 40K
by HPGe gamma spectrometer. The concentrations Bq/kg
ranged from 748.07 to 1459.94, 926.75to 1845.90, 43.75 to97.13,
17.58 to 68.09, and from 684.27 to 2019.21 for 238U,
226Ra, 232Th, 235U, and 40K
respectively. The 226Ra/238U, 238U/235U,
and 238U/232Th ratios in samples ranged
between1.00-
1.81, 17.00-18.50, 9.43-21.14
respectively. These variations in the concentrations of
radioelements and their ratios are due to the action of the
alteration processes. The Raeq ranged from
1042.00 to2045.45 Bq/kg with
mean value 1550.72 Bq/kg. The Raeq in all samples
exceeds the permitted limits (370 Bq/kg). Absorbed Dose Rate (nGy/h)
ranged from 482.64 to 949.02 with mean
value 720.53, Annual Effective Dose (mSvy/h) ranged from0.59
to 1.17 with mean value 0.88, and External Hazard Index
ranged from 2.82 to5.53 with mean
value 4.19. From the obtained results, the mean value of
Annual Effective Dose (0.88) is higher than the permissible
levels (0.48)
and
the calculated average value of external hazard index is higher
than unity. This result points to a dangerous effect in that
region for human health.

Abstract:
This paper presents a new and
practical method for the loss allocation in the deregulation
systems. The restructured markets sell the electricity in two
main categories; bilateral exchanges and pool based. In
reference 1, the losses in bilateral market using game theory
has been assigned to each player [1]. The method which is used
in this paper investigates the loss allocation in both markets.
The deregulated systems are not under control of one person but
there are other players such as generators and loads at which
every one of such players has to pay the cost for some parts of
system loss. The method used in this paper is to be fair the
loss allocation. This method is consisted of two different
categories; one finding the losses and the other is loss
allocation using Game Theory. To test this method, IEEE 14 buses
system is put in use. This paper takes the allocation of losses
in the hybrid market (Combined Pool / bilateral).

married women working in Faculties of Ain Shams University.
Tool: an interviewing questionnaire for assess the
socio-demographic characteristics of the menopausal women, their
knowledge, following of screening test, their health complaints
associated with menopausal transition and their
practices of dealing with menopausal health complaints.
Results: the mean age of perimenopausal women was 50.8
±
5.57 year. 100% of perimenopausal women had unsatisfactory
knowledge regarding to meaning and types of hormonal therapy,
81%and 79% of perimenopausal women had physical and social
health complaints, while 74%and 71% of
them had sexual and psychological complaints respectively,
84.5%, 83%, 82% and 67.5% of them had improper dealing with
psychological, sexual, physical and social health complaints
respectively. Conclusion: The finding of this study
showed that there was statistically significant relation between
women's knowledge and their following of health screening test,
a highly statistically significant relation between women's
knowledge and their dealing with health complaints, as well as a
highly statistically significant relation between women's income
and their dealing with health complaints. Recommendations:
This study recommended that there is a need to increase women
awareness through different setting as outpatient clinics,
maternal and child health and family planning centres to provide
more explanations about menopausal transition and its effect on
marital relationships and their health.

Abstract: The
purpose of this research was the study of predicting academic
achievement based on the dimensions of motivational orientations
and learning strategies. In the present study, statistical
population included,all male students in the third year of high
school in Hamadan, who were selected from the statistical
population of 331 people by using the multi-stage cluster
sampling method. The instruments were motivation orientations
scale (Wallerend & etc, 1992) and learning strategies
questionnaire (Winestein & Mayer, 1896).Academic achievement was
measured by using the GPA in the first semester 2012-2013.
Multiple regression analysis showed that, the strongest
predictor for achievement is Amotivation variable. In addition,
Elaboration Strategies also had the highly strength of
prediction. The implication for the educational practitioners is
obvious: motivational variables, especially intrinsic ones must
be focused on .Teaching methods should be directed toward
making, the subjects and learning strategies more interesting.

Abstract:
The motivation of movement is
created by human. However, it is related to whether meanings,
body forms, empirical phenomena, It is resulted from the context
of the social or tangible life of the people and as a stimulus
in human way. Movement which is the most important part of all
the space experiences, and the perception of space, relies on
movement. Everything in the world is dynamic and moving. The
movement allows us to realize the hidden beauty and discover it.
The aim of this article is the recognition of the concept of
movement from, Molavi's view and explanation quality of
manifestation in Islamic architecture space. The key question is
how the concept of movement is indicated in, Molavi's Thought
and what the representation of the concept of movement from ,
Molavi's view is in the Islamic architecture. In this article,
the research and qualitative research methods to answer the
questions, and library method according to inductive approach
for collecting the required information are used. Some examples
of Islamic architecture which considered the concept of movement
have been selected. As a result, dynamics and deterioration of
movement that Molavi's defined can be identified in Islamic
architecture space. Architecture is a tri-dimensional art. It
means, by moving its inside you will understand its details. The
sense of movement is to reinforce the function of the building
and the need to move according to the function of the building
caused the architect to create the of the sense of movement by
using of different elements, such as geometric patterns,
hierarchy, rhythm, transparency, axis, difference in surface,
spatial coherence, light and water.

Abstract:
The old fabric of Arak is the first pre-thought city in the
history of Iran that was constructed based on a pre-planned
design. Therefore, all stages of the construction in this city
from beginning to end including orientation, spatial
organization, height order, composition of land application etc,
were first designed and then executed. Goal of the research is
to identify urban design features of Arak old fabric from
Qajar period including landscape, town planning, development,
activities distribution, communication networks, Combination of
main elements, physical structure, Order of space division etc.
The hierarchical method has been adopted in order to analyze of
urban design properties from the whole to components, in such a
way that the process of urban designing is analyzed in an order
from zone to district, city, city center and eventually
quarters. Conclusion of the study is presentation of urban
design properties in different scales & phases.

Abstract:
Relation between Iraq and Iran,
during recent B years, indicates developing trend of exporting
gods to this country and making Iraq as the second exporting
partner. Exploring Iraq's geography, it was noticed that more
than 80% of population, and economic, service, cultural and
shelter equipment in this country lies in Midwest that are close
to Iran Borders. This can be a valuable help to the expansion of
trade borders. Currently, border trade transactions with Iraq is
made through border marketing and borders. The number of border
marketing's with Iran are 13 and defined formal trade borders
are khosravi, Mehran and shalamche that are placed in
kermanshah, Ilam and Khuzestan provinces that are posited in
west and southwest of Iran. The purpose of this paper is
selection of ideal border area for expending trade Iraq. In this
regard we used one of the ideal selection methods of places in
theories of location and ranking methods of borders, according
to which Mehran border lies in the first rank.

Abstract :
Hip surgery
including total hip replacement and hip fracture surgery are
very successful orthopaedic procedures that relieve pain,
improve function and enhance the quality of patients’ lives.
However, these procedures are also associated with a risk of
morbidity and mortality from the development of DVT and its
sequel, pulmonary embolism (P.E.) Occurrence of DVT will lead to
emotional consequences of pain, extended isolation and impaired
social interaction that have impact on every aspect of patient’s
life (18-20).Consequently
more attention has to be paid to nursing interventions related
to DVT prevention in orthopedic health care. Therefore; the
present study aims to establish nursing standards for
prophylaxis of DVT among patients undergoing hip surgery. This
study was conducted at EL-Hadara Orthopaedic and Traumatology
University Hospital in Alexandria. Jury subjects
consisted of experts from the following categories:- faculty
members of Medical Surgical Nursing Department, Faculty of
Nursing, Alexandria University (20), Ten orthopaedic surgeons
from Faculty Of Medicine, all head nurses working in the
hospital (10) and ten vascular surgeons from Faculty Of
Medicine, Alexandria University. DVT prophylaxis opinionnaire
was developed by the researcher after reviewing related
literature to elicit opinions of expert groups regarding
hospital structure and process standards. The study
established valid and
reliable nursing standards for prophylaxis of DVT among hip
surgery patients.

Abstract:
In This
paper an experimental and numerical program was adopted to
investigate the interface effect of shallow strip foundations
constructed on homogeneous sand reinforced by geogrid. The
ultimate bearing capacity of a number of multiple footings in a
group becomes always greater than that of a single isolated
footing. Several parameters including soil type, spacing between
interfering footings and the foundation level under both uniform
and eccentric vertical loads were examined. A detailed numerical
analysis study was performed to investigate the effect of angle
of internal friction, foundation level and load eccentricity on
bearing capacity. The failure stage in the sand was controlled
using hyperbolic relationship between strain and stress level.
The best location of interfering footings was determined to
achieve the maximum bearing capacity for closely spaced strip
footings and it was found that the best clear spacing between
footings was 0.4 and 0.6 times the footing width for reinforced
and unreinforced sand, respectively. Some significant
observations on the performance of footing-geogrid systems with
change of the values of parametric study are also presented in
this paper.

Abstract:
Years ago, the world underwent a
shift in wealth, but now something is happening and we are
facing this change, in the nature of wealth. Today all the
categories of wealth tend to be knowledge based. WTO statistics
show, the global economy focuses on knowledge-based products and
a country like Iran with 100 years of experience in the oil and
gas industry can achieve advantages through exporting
engineering and technical services. But it is not always so
smooth; lethargy in the Iranian oil and gas industry shows that
knowledge is not solely enough and extremely needs special
strategies for development. We think the theory of BSC is able
to achieve it and improve many weaknesses such as structural
false on the way of developing the technical and engineering
services. This paper discusses the ways through BSC that enable
Iranian oil and gas knowledge to achieve its goals via
developing technical and engineering exports and financial
advances.

ABSTRACT:
The
present investigation was carried out at the laboratory of
Biofertilizer Center, Minia University and the Experimental
Farm, Fac. of Agric., Minia University during 2011 and 2012
seasons to study the effect of N fertilizer, three Azotobacter
isolates and their interactions on growth yield and chemical
composition of Jerusalem artichoke
(Helianthus
tuberosus
L.,). The
use of Isolate 3+50% recommended dose of
n.
fertilization gave the highest level of shoot fresh weight in
both seasons. The results also showed that use isolate 3 was
more efficient than neither Isolate 1 nor Isolate 2 for
increasing fresh weight. The same trend was also observed when
shoot dry
weight was studied.
Data of plant height (cm) indicates that use of Isolate 3+50%
chem gave significant effect on plant height in both seasons .
The reported results showed that the
bacterial isolates improved plant height and some other
vegetative characters of Jerusalem artichoke plants only when
50% of the N recommended dose were applied. These results showed
that the values of number of branches/plant in all treatments
don't exceed those recorded for control. The highest values of
tubers weight on fresh basis were recorded when Isolate 3+50% N
was applied (4.9 kg fresh weight basis (fwb)) in the first
season and (4.83 kg fwb) in the second season whereas the lowest
ones was recorded for control +50% chem (3.2 kg fwb).
The
heaviest tuber fresh weight values were 86.13 and 91.43 g for
treatment included Isolate 2+50% chem. in the first and second
seasons, respectively. The treatments applied in the present
work led to significant increases in the weight of single tuber
with different extents ranged from 208% to 264%.
The results of the dry weight of 100 g
of tuber showed that all treatments increased this character
except control+50% N
which decreased this character
(22.43g). The
effect of the bacterial isolates plus N fertilization at 50%
dose ordered as follows: Isolate 1 > Isolate 2 > Isolate 3
whereas at 100% N fertilization where Isolate 2> Isolate 1>
Isolate 3.
Accumulation rate of dry matter was highest in tubers treated
with Isolate 1+100% chemical fertilizer followed by treatment-3
Isolate 2 + 100% chemical fertilizer).
The results
showed that combining Azotobacter isolates and chemical N
fertilization increased dry matter by 181% when compared with
control. The concentrations of total phenolic compounds (TPCs)
in whole tuber extracts of Treatment-4 which formed from Isolate
1+100% N were higher (52.5 mg/100g fw) than those determined in
control with extent reached to be 235%. The concentrations of
total flavonoids (TFs) ranged from 56 to 145 µg/100 g fwb in
control sample and Treatment-4 respectively. The results also,
showed that the differences between treatment-3, treatment-4 and
treatment-6 are not sharp and ranged from 139 to 145 µg/100 g
fwb. The total soluble sugars (TSS) assayed in the samples
ranged from 6.9 to 11.6% in untreated sample and Treatment-6
respectively.

Abstract:
This study was conducted to evaluate morphological
characteristics and chemical constituents of six seeded grape
varieties of the Vitis vinifera L. grapes namely: Rich
Baba; Red Globe; Roumi Ahmer; Black Rose; Matrouh Eswed and
Ribier. Results indicated that Ribier and Matrouh Eswed recorded
the lowest number of seeds per berry, followed in an ascending
order by Black Rose, Roumi Ahmer, Rich Baba and Red Globe. Red
Globe, Black Rose and Rich Baba recorded the highest average
weight of seeds per berry, while Roumi Ahmer, Ribier and Matrouh
Eswed recorded the lowest average weight of seeds per berry.
Black Rose, Red Globe and Roumi Ahmer seeds recorded the highest
total carbohydrates content, while Rich Baba, Matrouh Eswed and
Ribier seeds recorded the lowest total carbohydrates content.
Black Rose, Red Globe, Roumi Ahmer and Rich Baba seeds recorded
the highest crude protein content, followed by Matrouh Eswed and
Ribier seeds. Black Rose and Red Globe seeds recorded the
highest tannins content, followed in a descending order by Roumi
Ahmer, Rich Baba, Ribier and Matrouh Eswed seeds. Black Rose,
Red Globe, Roumi Ahmer and Rich Baba seeds recorded the highest
oil yield, while Matrouh Eswed and Ribier seeds recorded the
lowest oil yield. From these findings, it can be concluded that
Black Rose, Red Globe, Roumi Ahmer and Rich Baba seeds could be
used in animal feed production, based on the high carbohydrates
and proteins. Although Matrouh Eswed and Ribier seeds are low in
carbohydrates and proteins content, they are still suitable for
animal feed production due to the low tannins content. Black
Rose, Red Globe, Roumi Ahmer and Rich Baba seeds are suitable
also for production of oil, due to the high oil yield with high
level of unsaturated fatly acids, which gives it excellent
dietetic properties for human consumption and makes it useful in
the field of various food industries.

Abstract:
Objectives:
To compare the effects of
intravenous calcium infusion and coasting in the prevention of
the early onset ovarian hyperstimulation syndrome (OHSS) in
high-risk women underwent ICSI.
Study design:
Prospective randomized trial.
Patients and Methods: Sixty women at risk
of ovarian hyperstimulation syndrome during ICSI cycles were
randomly scheduled into two equal groups. In group I,
(Intravenous calcium group), intravenous 10% calcium gluconate,
10 mL in 200 mL of normal saline (0.9%) was administered on the
day of ovum pickup, days 1, 2 and 3 after ovum pickup; while in
group II (Coasting group) gonadotrophins administration was
ceased until serum estradiol levels checked every 24 hours,
reached below 3000 pg/ mL before HCG administration.
The main outcome measures were rates and grades of OHSS, and the
pregnancy rate in both groups.
Results:
Ten patients (33.33%) in calcium group and 15 patients (50%) in
coasting group developed OHSS. The
incidence of mild {8 (26.67%) vs 10 (33.33%); p= 0.573},
moderate {2 (6.67%) vs 4 (13.33%); p= 0.389} and severe
{Zero vs 1 (3.33%); p= 0.313} OHSS were nonsignificantly
lower in calcium group compared to coasting group. The clinical
pregnancy rate was nonsignificantly higher in calcium group
compared to coasting group (40% vs 23.33%; p= 0.165). The
mean number of retrieved (p =0.0002), metaphase II (p
= 0.007) oocytes and the mean number of good-quality embryos (p
= 0.0002) were significantly higher in calcium group than
coasting group. Conclusions:
Intravenous calcium infusion was as effective as coasting in the
prevention of early severe OHSS in high-risk patients, but
yielded more retrieved oocytes and higher pregnancy rates.

Abstract: Worldwide
more than 140 million people suffer from diabetes mellitus,
which is one of the most common non communicable diseases.
Diabetes mellitus magnifies the risk of cardiovascular morbidity
and mortality and is known to be the major risk factor for
development of coronary artery disease. The purpose of this
study was to compare the coronary angiographic findings in
diabetic and non-diabetic women in upper Egypt with non ST
segment elevation myocardial infarction.
The present study was conducted in a
co-operation between Cardiology Department Faculty of Medicine,
Al-Azhar University and Cardiology Department, Luxor
international hospital over a period from December 2009 to
December 2010.
The present
study included 30 female patients
presented with Non ST segment
elevation myocardial infarction,
patients were
divided into 2 groups:
Group (I) Fifteen diabetic patients (56.133± 7.049 years old), group (II) Fifteen Non diabetic patients (56.267 ±
8.189 years old). Transthoracic
echocardiography (including M-mode, 2D and Doppler imaging) with
standard views have been taken.
Coronary angiography
was done for all patients. Regarding age and other risk factors,
there was no statistically significant difference between the
two groups (P 0.0962). The number of diabetic patients with
single vessel disease was 5, with two vessels disease were 3,
and with three vessels were 6, while the number of non diabetic
with single vessel disease was 12, with two vessels disease was
1, with three vessel disease was zero and the difference between
the two groups was statistically significant (P 0.01). The
affection of RCA was more common in group I than group II.
Presence of collateral circulation was more in group I than that
of group II. Type A lesion was more prevalent in group II
compared with group I while type B and C lesion was more in
diabetics and the difference between the two groups was
statistically significant (P 0.01). Seven diabetic patients had
undergone PCI, 7 had CABG decision, and 1 received medical
treatment while in the non diabetic patients, the PCI was done
for 13, no CABG, and medical treatment for 2 of them and the
difference between the two groups was statistically significant,
there was a statistically significant difference between the two
groups as regard to echocardiographic findings (P 0.001).
Diabetic patients had more multiplicity of coronary artery
affection, more diffuse disease and more severe stenosis, the
affection of the right coronary artery was more common in
diabetic patients, morphology of coronary lesions was more
complex in diabetic patients than the non diabetics, diabetic
patients had developed collateral circulation and left
ventricular systolic dysfunction more than non diabetics.

Abstract:
Aim and Background: Examination of environmental samples such as
manure and soil could be
considered as an alternative
screening technique for the detection of MAP. So it may improve
the efficiency of Johne’s Disease control strategies especially
in areas with low MAP prevalence.
This study was conducted to evaluate and investigate the
usefulness of environmental samples and especially milk-filter
samples in the improvement of MAP diagnosis. In addition, the
present work aims to investigate the possibility of using these
samples as an alternative cheaper diagnostic matrix for MAP-
detection in dairy herds.
Methodology: Manure and milk filter
samples were collected from 63 German dairy cattle herds in
Hessen to be investigated for the presence of
Mycobacterium avium subsp. paratuberculosis
(MAP). All herds included were
tested for MAP status in a previous study by screening with the
Pourquier®
ELISA
and bacterial isolation from individual faeces and/or milk
samples.
Results: MAP was identified in 11.2% and 3.6% of tested manure
and milk filter samples respectively. Grown colonies were
characterized by phenotypic characters, Ziel Neelsen stain and
by PCR amplification of MAP the IS900 sequence and the f57
gene. Conclusion: The current study is the first
report of the isolation of MAP from milk filters highlighting
the usefulness of this kind of sampling in the identification of
MAP on herd level. Moreover, such environmental sampling could
aid in the future as a cheaper alternative screening techniques
for detecting MAP status on herd level.

Abstract:
The association between obesity and type 2 diabetes mellitus
(T2DM) has been recognized for decades. The major basis for this
link is the ability of obesity to engender insulin resistance (IR).
Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) is an
indirect marker of IR. The present study evaluated the
usefulness of HOMA-IR in the prediction of the risk of the
development of T2DM among overweight and obese individuals in
Najran, Saudi Arabia. This study was carried out on 116 male
individuals divided into 3 groups. Of these, 20 healthy control
(GI), 44 prediabetic overweight and obese individuals with high
normal serum glucose levels (GII) and 52 diabetic overweight and
obese individuals with high serum glucose levels (GIII). Body
mass index (BMI) was calculated for all individuals. In
addition, fasting serum glucose and insulin levels, lipid
profile and liver and kidney function tests were estimated for
all individuals. The mean BMI was 21.84±1.28 kg/m2
in GI, 28.68±2.42 kg/m2 in GII and 33.82±2.78 kg/m2
in GIII. The mean fasting serum glucose was 128.29±27.92 mg/dl
in GII and 159.46±44.86 mg/dl in GIII. Such findings were
correlated with increased fasting serum insulin levels
(21.57±2.58 µU/ml in GII and 37.28±6.15 µU/ml in GIII) compared
to GI (16.22±6.23 µU/ml). The mean HOMA-IR was 5.77±1.71 in GII
and 12.67±4.07 in GIII compared to GI (4.07±1.04). We conclude
that, increased BMI was associated with increased incidence of
Insulin Resistance, dyslipidaemia and hyperuricaemia among
overweight and obese individuals in Najran, Saudi Arabia.

Abstract:
Semi-active suspension system is a possible way to improve
suspension performance although the passive system can
effectively handle some control of suspension system. The main
propose of this paper is to assess performance of semi-active
suspension system by implementing Fuzzy and
Proportional-Integral-Derivative (PID) controls in comparison
with passive suspension system. This paper is focused on
reliable fuzzy controller design for pneumatic semi-active
suspension system.
The pneumatic semi-active suspension system consists of a damper
with two state variable damping coefficient parallel with coil
spring. The performance of pneumatic semi-active suspension
system theoretically
and experimentally predicted using two degree of freedom of quarter car model are
presented. Also a method of PID and fuzzy controls were applied
theoretically and experimental to show the performance of ride
comfort. The results are generated when the system is excited by
sine wave road input. The damping coefficient of the pneumatic
semi-active damper is taken firstly from the experimental on the
damper characteristics test rig, after that, the performance was
studied using the quarter car test rig. Finally, a comparison
between the passive and semi-active systems are presented and
discussed. The results showed that there is a worthwhile
improvement for the pneumatic semi-active suspension system with
fuzzy control over the passive.

Abstract: The aim of this study
was to
assess the stresses induced by RPI, I-bar and RPL clasps and
their effect on bone height of the structures supporting
asymmetric distal extension partial dentures. Materials and
methods: The stresses induced by the three partial denture
designs and their effect on marginal and crestal bone loss were
compared. In-vitro strain gauge analysis was used to measure the
stresses induced by the three direct retainers. The change in
marginal and crestal bone height was measured using
radiovisography (RVG). Results: Comparing the
micro-strains induced by placement of the RPL clasp on the
abutments, revealed statistically significant less micro-strains
induced to abutments on both short and long sides of the ridge
compared to RPI and I-bar clasps. The placement of I-bar clasp
on short side abutment induced the greatest & statistically
significant micro-strains to the short side of the ridge but the
least statistically significant micro-strains on the long side
of the ridge, while the stresses induced by placement of the RPI
clasp on the short and long sides of the ridge were
statistically insignificant. Statistically significant less
value of marginal bone loss of abutments bearing RPL clasps was
detected at the end of the study period compared to that caused
by RPI and I-bar clasps. However, no statistical significant
difference was noted between the effect of RPI and I-bar clasps
at the end of the study period. Conclusion: The results
revealed that asymmetric partial dentures retained on the short
side by RPL clasp induced less stresses and caused less bone
resorption compared to dentures retained by RPI clasp and I-bar
clasp.

Abstract:
The philosophy of
education can be studied from different viewpoints of thought,
containing the three important groups; Western, Eastern and Islamic philosophies.
Regarding to this arrangement, there are several aspects that are
not match with each other, whenever comparing these aspects
within the comprehending of education itself, through the
countries apart of this global nation. The idea and the
conception of philosophy of education has been derived
traditionally and modernly, became combined and simultaneously
work on each other, in order to generate the best culture of
education to the humanity. Thus, this paper attempts to perceive
structural changes in architectural education system in Iran due
to the effects of various factors such as hermeneutic mutations
in parametric and algorithmic architectural education. As a
result, the samples of design in 2 schools of architecture have
been considered.

virtual classrooms to remote courses or distance learning.
E-Learning, via Web-based courses, offers obvious advantages for
learners by making access to educational resources very fast,
just-in-time and relevance, at any time or place. In this paper,
we present a vision of e-Learning for higher education
institutions in Jordan, in general, and for The University of
Jordan, in particular. In addition, we propose an approach for
developing e-Learning Strategic Plan for the University of
Jordan particularly. The Plan provides a roadmap for the
effective integration of appropriate Web-based educational
technologies and services as well as e-Learning management
systems to strengthen the teaching and learning missions of the
University of Jordan, on-campus, between campuses, and online.

Abstract: Background:
Retinol binding protein 4 (RBP4) is an adipokine that had been
reported to induce insulin resistance and to play a role in the
pathogenesis and severity of essential hypertension (EH).
Aim:
was to evaluate RBP4 levels in patients with EH and to
investigate the relationship between raised serum RBP4 and
insulin resistance in hypertensive (HTN) male patients and its
relation with the severity of hypertension and risk of
left ventricular hypertrophy (LVH).
Subjects and Methods:
serum RBP4, insulin, blood glucose, uric acid, creatinine,
high sensitivity C-reactive protein (hs-CRP) and lipid profile
were investigated in HTN male patients, together with
measurement of homeostasis model assessment (HOMA) index for
insulin resistance, body mass index (BMI) and waist
circumference. The patients were divided into two groups;
hypertensive patients with metabolic syndrome (MS) and
hypertensive patients without MS and compared with age and sex
matched apparently healthy individuals as control.
Results:
HTN patients with MS were found to have significant higher
values of RBP4, BMI,
waist circumference,
HOMA index, uric acids and triglycerides with high prevalence of
LVH compared to patient group without MS. Serum RBP4 was found
to be positively correlated with high levels of systolic and
diastolic blood pressure and with high values of HOMA index, and
negatively correlated with HDL.
Conclusion:
serum RBP4 can be used as a predictive marker for the severity
of hypertension and associated risk of LVH in
HTN patients with MS.

Abstract:
Alveolar atrophy following tooth
extraction remains a challenge for future dental implant
placement. Immediate implant placement and postextraction
alveolar preservation are two methods that are used to prevent
significant postextraction bone loss. The purpose of this
study is to investigate the usefulness of
hydroxyapatite / beta tricalcium
phosphate (HA/BTCP)
with
hyaluronic acid (HY) for
alveolar sockets preservation. Thirty-two New Zealand white
rabbits were subjected to
the lower left incisor extraction. The rabbits were equally
divided into three groups. The extracted sockets
(n = 12/group)
were filled
with : HA/BTCP, HA/BTCP +
HY and
blood clot
(control).
All rabbits
were sacrificed for histological and histomorphometric
evaluation after 4 and 8 week healing periods.
The results demonstrated that
all sites examined in this study
displayed evidence of new bone formation. A statistically
significant difference in the amount of new bone formation were
found between sites that healed for an average of 8 only. The
results demonstrating approximately 78%, 68 % and 63% of new
vital bone formation for groups grafted with HA/BTCP +HY, HA/BTCP
and control group respectively after 8 weeks postoperatively. In
conclusion these results exhibited that the use of
hydroxyapatite / beta tricalcium
phosphate
with
hyaluronic acid
appears to be more efficient in osteoconduction when compared
with of hydroxyapatite / beta tricalcium
phosphate alone and could be promising strategy for
preservation of alveolar sockets.
