Abstract: Resistance
training is becoming increasing popular in the Middle East,
especially in Kuwait. At the same time, the use of
anabolic-androgenic steroid (AAS) has been increasing
tremendously by Kuwaiti recreational bodybuilders seeking to
gain muscle mass and improve their physique. Therefore, the
purpose of the present study was to determine the side effects
of anabolic-androgenic steroid use on Kuwait recreational
bodybuilders who have been using AAS. Blood parameters of male
bodybuilders (n=70; age=26±3yr) who have been using AAS were
studied. Eighty two percent of bodybuilders showed increased
levels of both alanine aminotransferase (ALT; 48±38 U/L) and
aspartate aminotransferase (AST; 41±32 U/L) above the upper
range of reference. Moreover, in regard to hormones, 69% of
participants had estradiol levels above the upper reference
limit (57±1.34 pg/ml), but otherwise, all other hormones were
within the normal range. Most Kuwaiti bodybuilders use AAS will
experience without medical supervision Therefore, the ministry
of health in Kuwait should implement strict regulations and
increase awareness among recreational bodybuilders of potential
health problems associated with AAS use.

Abstract:
This work can be considered as an effort to recognize the
relationships between the drawdown and recovery data for the
aquifer system, and instead of separated two graphs including
Cooper – Jacob for the pumping test and Theis recovery straight
line methods, Elhag (2014) innovational simplified solution
agrees with more complicated solutions, and useful for determine
aquifer parameter values in one graph that well be collecting
the data of pumping and recovery tests and plotting two straight
lines crossed in optimum point (sopt.). It’s matching
together in contrast of drawdown and recovery data, which is
used to start compute the slope of the straight line per one log
cycle and the end of this cycle equal the distance between the
two straight lines (∆s1). Generally the result values
of the new method proposed is agreement with the results of the
classically known technique and appear to be complimentary to
current methods such as Theis type curve, Cooper – Jacob and
Theis recovery. The statistics of aquifer parameter pair (T and
S) values relatively low average percentage errors that range
from 3.9 to 3.7% respectively.

Abstract: Recently, porous templated materials have attracted significant
attention owing to their unique properties and their potential
applications. The ease of preparation and control of the surface
functionality (basic and/or acid/base) of the mesoporous
aluminosilica oxynitride materials makes them attractive as
alternative solid acid/base catalysts, especially for
large-molecule transformations. Mesoporous silica materials are
currently the subject of intense research interest. Herein, the
method of preparation and structure characterization of
composite micro/mesoporous crystalline materials consisting of
novel solid acid-base mesoporous aluminosilica oxynitride
materials been presented. Experiments been performed using
previously reported procedures to this purpose. The preparation
procedure involves two-steps: i) formation of a mesostructured
material composed of zeolite aluminosilicate micro/mesoporous
material by a crystallisation process, varying the aging time
between 2 – 16 h and ii) the calcined samples been subjected to
high temperature nitridation, i.e. treatment with ammonia at
elevated temperature. The produced nanostructured acid/base
micro/mesoporous aluminosilica oxynitride materials was
investigated using a variety of techniques including powder
X-ray diffraction (XRD), nitrogen sorption, thermo-gravimetrical
analysis (TGA), X-ray fluorescence (XRF) and elemental analysis.
Results showed the possibility of generating composite materials
of a cubic MCM-48 phase and zeolite ZSM-5. The textural
properties of the composite materials confirmed that the
materials exhibit various levels of micro/mesoporous structure
with relative narrow pore size distribution. The maintenance of
the structure ordering after a nitridation treatment were found
depends on the conditions of the treatment with ammonia.

Abstract: In this article the relationship between earnings
quality with earnings stability index and future profitability
has been investigated. Accordingly, three hypotheses were
formulated. The first hypothesis investigated the relationship
between profit stability and future profitability, the second
hypothesis investigated the relationship between accruals and
future profitability, and the third one investigated the
relationship between operational cash flow and future
profitability. To do this, 84 companies among the accepted
companies in Tehran securities exchange were investigated during
2007 to 2014. To evaluate the earnings quality pooled data
method was used, and then the hypotheses testing was implemented
using multi-variable regression model. The results of this study
show that there is a significant positive relationship between
earnings quality and future profitability, and earnings
stability is an appropriate tool to measure earnings quality and
durable and stable earnings can be used to predict the future
earnings.

Abstract:
Soil is a major reservoir for
contaminants as it possesses an ability to bind various
chemicals. The purpose of this research work is to introduce to
the reader the fundamental processes that control the mobility
of metals in the soil environment. The metals selected for this
research work are the metals most commonly found at sites and
will be limited. A study was conducted to investigate to study
accumulation of heavy metals in soil samples collected from the
surface of the soil near Sudha dam area in Bhokar, Maharashtra.
These chemicals can exist in various forms in soil and different
forces keep them bound to soil particles. It is essential to
study these interactions because the toxicity of chemicals may
strongly depend on the form in which they exist in the
environment. Another thing is that soil variability and some
environmental properties (e.g. climate factors) may change
equilibrium found in soil and cause leaching of trace toxic
elements like heavy metals tightly bound to soil particles. The
concentration of these metals was determined by
UV-spectrophotometer. The concentration of heavy metals was
found to be below the permissible limits.

Abstract: Genomics
is a field of study that is rapidly transforming many areas of
biological and biomedical research which has enabled the
transition from sequential studies of single genes to more
ecological approach, involving the simultaneous study of many
components and their interactions with the environment from
pathways, through cell tissues to whole organisms and
communities. Genomics application areas include clinical
diagnostics, agro biotechnology, environmental biotechnology and
pharmacogenomics. The focus of most genome research is on the
nuclear genome, though mitochondrial genomes have been extremely
useful for the identification of fish species and populations.
Marine microbial assemblages are diverse and unique and the
challenge is to discover what functions are played by these
microorganisms. To provide adequate tools for marine biologists,
therefore, one important aim will be to develop genomic
approaches, such as whole genome sequencing and functional
genomics, for key species across the evolutionary tree of marine
organisms. Genomics is a highly dynamic research field. Hence,
rapid developments in genomics can afford new opportunities for
applications in marine environment, particularly in the areas of
Fish genome resources conservation and genetic enhancement.

Abstract: Language
plays a crucial role in the development of human society. It is
the main means of communication between individuals, groups and
countries. Nowadays, more and more people are learning English
as a foreign or second language, and their key objective is to
get expertise in English. This has ignited a spark in the
teachers to innovate and adopt the effective methods of teaching
English which is a matter of great concern today. Language
acquisition involves four modules of teaching that includes
Listening, Reading, Speaking and Writing. The teachers have to
be dynamic and updated to teach these language skills to the
students. The researcher has interviewed the participants on
various aspects involved in teaching-learning process to find
out the root cause of the problems encountered by students
studying at Jazan University to attain the speaking and the
writing skills. The problems are further critically analysed,
evaluated to derive at conclusions to suggest the most
appropriate measures to be taken by the language teachers to
overcome the problems of the students to enhance and expertise
in their productive skills.

Abstract: One to one
correspondence can be referred to as a relation between the
elements of two sets, where every element of one set is paired
with exactly one element of the other set, and every element of
the other set is paired with exactly one element of the first
set. There are no unpaired elements. In the same way, Assignment
problem deal with assigning n items/activities/tasks etc to n
machines/workers/contractors etc in the best way so that no one
activity gets more than one machine/worker and no one worker get
more than one activity assigned to it. In this paper one to one
correspondence is examined with its applications to linear
Assignment problem. A one to one correspondence algorithm for
solving linear assignment problem is presented. Finally
numerical problems were solved for both minimization and
maximization assignment problems for further understanding, and
it was observed that the optimal solution is obtained faster and
easier than the existing methods.

Abstract:
New resins based on crosslinking of peanut testa catechin units
with phosphorus oxychloride have been synthesized from
abundantly available but menace-causing peanut testa waste. The
synthesized resins were converted to strong and weak cation
exchangers by functionalizing with chlorosulphonic and
monochloroacetic acid respectively. FTIR spectra of chemically
modified peanut testa catechin resins showed a
disappearance/reduction in the intensity of –OH band at 3400 cm-1
and the formation of new ones at 1325, 1345, 855, 1240 and 990
cm-1 showing the stretching vibrations of O=S=O, --SO3,
R-- O--S--, -P=O and -P-O-R bands respectively. New bands around
1743 and 1190 cm-1 reveal the presence of –C==O and
–C—O- groups respectively on carboxymethylated phosphorus
oxychloride crosslinked peanut testa extract. Specific gravities
of the cation exchange resins lie between 1.08 and 1.79 g/cm3.
The resins were stable above 300°C, insoluble in common organic
solvents: methanol and ethanol, water and solutions of pH< 9 but
were soluble in alkaline solutions of pH ≥10. The point of zero
charge (pHpzc) and cation exchange capacity (CEC) values ranged
between 2.2- 4.2 and 0.62- 5.9 respectively.

Abstract:
The manager should compare current personal interests with
flexibility obtained by keeping cash fund reserves. In addition,
the profit-seeking managers ought to measure the probability of
increasing interests' ratio to expenditure
coming from keeping more cash fund. Conservativeness in the
field of accountancy has been criticized in many cases while
other experts have upheld it. In the current study it is tried
to scrutinizing the continuity of the profit growth and
conservativeness in the field of accountancy. The project
includes all companies listed in Tehran Stock Exchange except
the investment companies, banks and insurance companies, which
have the needed qualifications for the research. The sample
includes 102 companies, selected by “omitting the systematic”
method in 2008-2012. The method is multivariate regression. The
research results shows the negative relation of continuity of
the profit growth and conservativeness, which means the increase
of conservativeness decreases the continuity of the profit
growth.

Abstract:
One of the promising ways of combating poor ruminant nutrition
and under-utilization of available pasture forages is studying
the behaviours of grazing animals, especially goats. This is due
to the fact that lack of sustainable ruminant feeding strategies
contributed to the slow growth and high mortality of ruminants
in Nigeria. The comparative grazing behaviour of Thirty eight
goats; comprising Thirty three West African Dwarf does and Five
Maradi bucks with Average Weight of 9.50kg and 15.45kg
respectively, were observed in the study for a period of 6
weeks. Standard procedures were used to underscore the grazing
behaviour of WAD and Maradi goats and proximate composition of
the forages. The parameters measured under grazing behaviour
are: grazing, ruminating, walking, drinking and resting while
crude protein, crude fibre, ether extract and ash were assessed
in proximate composition. Data collected were subjected to
analysis of variance at P=0.05. For WAD, grazing was
significantly highest 53.20 and drinking (1.40) was the least
(P<0.05). While for Maradi the values ranged between 72.15 and
2.54 in grazing and ruminating respectively. Seven species of
forages consistently eaten through close observation by the
goats were identified and divided into forbs, grasses and
legumes. The percentage selectivity of forbs, grasses and
legumes for WAD ranged from 25-50%. While for Maradi, it ranged
between 33.33 and 33.34%. The forages proximate analysis range
for crude protein was from 6.17-23.47%, crude fibre
11.97–33.00%, ether extracts 8.50–10.50%, ash 5.50-17.33%. The
study showed that breeds of goats exhibit different grazing
behaviours when raised on pastures composed of different forages
with varying nutrient composition.

Abstract:
Background: One of the significant side effects of methotrexate
(MTX) was hepatotoxicity, for this reason the clinical use of
this drug was restricted. The present study was intended to
research the hepatoprotective impacts of bone marrow-derived
mesenchymal stem cells against methotrexate, based on
histological, immunohistochemical and ultrastructural
parameters. Material & methods: Twenty four adult male albino
rats were randomly divided into four experimental groups. Group
I represented as control. Male adult albino rat received
intramuscular (IM) injection of MTX (10 mg/ kg B wt.) once
weekly for 6 weeks (group II) and others held for another 6
weeks without therapy then were sacrificed (group III). The rats
received single dose of BM-MSC sintraperitoneal injection after
induction of hepatic damage with MTX served as group IV. Light
and electron microscopy were done to evaluate the
histopathological changes. Results: Suppressive effect of BM-MSCs
on activated hepatic stellate cells (HSC) was evaluated using
immunohistochemical staining. Several histopathological changes
were observed in liver cells of MTX‐treated animals; when
compared with hepatocytes of control rats, had depletion of
glycogen, distortion of hepatocyte and infiltration with some
inflammatory cells. Conclusion: Our finding proved that of BM-MSCs
injection after induction of hepatic damage with MTX induced
