Abstract Meconium
stained amniotic fluid (MSF) is a leading cause of neonatal
mortality and morbidity. The aim of this study was to assess
the association of umbilical cord vessels’ PH with pregnancies
complicated by meconium stained amniotic fluid. This cross
sectional study was conducted among 195 pregnant women. The
umbilical cord blood samples of 96 neonates (52 neonates with
normal vaginal delivery (NVD) and 44 with cesarean section
(C/S)) with MSF and of 99 neonates (49 neonates with NVD and 50
with C/S) with clear amniotic fluid were collected. DemograpHic
data (age, gestational age), antenatal characteristics
(duration of labor, active pHase and second stage of labor,
duration of induction, type of anesthesia), postnatal
characteristics (Apgar score at 1 and 5 min) was documented for
each patient. Women with preterm labor or other pregnancy
related diseases (hypertension, preeclampsia, gestational
diabetes mellitus, prolonged rupture of membrane) and
multifetus pregnancies were excluded. Data was analyzed using
SPSS (V.18) by statistical tests (independent T-test, chi –
square, ANOVA). P-value below 0.05 considered statistically
significant. The mean age of participants was 26.8 ± 5.4. The
mean PH value in all participants was 7.26± 0.07. There was no
significant difference between the two groups (case and
control) for PH (p > 0.05). The results showed that,
duration of active pHase of labor, Apgar score at 1 min and the
number of pregnancies had significant correlation with umbilical
cord PH (P < 0.05). There was no significant relation
between umbilical cord PH and duration of labor and second
stage of labor, meconium concentration, type of anesthesia,
duration of induction (p > 0.05). The mean umbilical cord PH
among patients with meconium stained amniotic fluid was higher
in neonates born thorough cesarean section. Apgar score at 1
min was related to umbilical cord PH.

Abstract: One of the solutions for the
security of the systems and computer networks is the formation
of intrusion detection systems. In the design of these systems,
the techniques of artificial intelligence such as neural
network, data mining techniques, expert systems, genetic
algorithms and fuzzy systems are applied. The main aim is the
design of the system that besides exact detection is with low
error. The main aim of detection in these systems is their
analyzer. It seems that if the input of analyzer of the systems
is language variables and final detection is done as fuzzy
inference, the results of the analysis get better and an exact
detection is done. In addition to reduction of error, it can
present good information in the form of fuzzy rules to the
security expert of the system. Genetic algorithms by flexible
and prevalent searching ability can be applied for optimized
learning of fuzzy system rule base. The current paper aimed to
evaluate, design and implement fuzzy genetic intrusion
detection system. The experiments and the results showed the
considerable effect of using the proposed architecture on the
improvement of detection.

The
Effects of Daily Coenzyme
Q10 Supplementation on VO2max,
vVO2max and Intermittent Exercise Performance in
Soccer Players
Nima Gharahdaghi1,*, Fatemeh Shabkhiz1, Ehsan
Azarboo2, Abbas Keyhanian3
Abstract: The
aim of this study is to assess aerobic, anaerobic and
performance indexes changes after a short period of coenzyme Q10
Supplementation in soccer players. 16 soccer players (Weight
57.1±20.72, height 171.4±4.92, and age 22.30±1.41) randomized
and divided into two groups. Where supplement group (N=10)
consumed CoQ10 supplement (300 mg/day) and placebo
group (n=6) consumed placebo. Both of them practiced for 4
weeks and each one 90 minutes. After that, supplement group
started to consume CoQ10 in amount of 300 mg/day for
one month. Findings has been showed that 4-week supplement
consumption caused significant changes in VO2max and
performance in soccer players, while this intervention did not
result in significant effect in body composition, maximum
running speed, peak anaerobic power and fatigue index. The
major findings of the present study were that 4-week of CoQ10
supplement consumption in college soccer players led to
increase aerobic power and performance in high intensity
aerobic interval test. From the other point of view, these
variations were not significant in placebo group. We can
conclude that although increase in maximum running speed (vVO2max)
was not significant, four weeks of CoQ10 supplement
consumption may increase in maximal oxygen consumption and
performance in college soccer players. Finally, in this case
consumption of this supplement could improve player’s
performance in competition conditions.

Abstract: Although worldwide prevention and
community information about AIDS has been developed in recent
decades, it is still considered as a problem for public health.
Dental students are at increased risk for HIV infection because
of overutilization and unsafe injections during surgery or
other procedures. Knowledge of dental students about HIV
infection and its transmission ways is an important subject in
health care system. The purpose of current study was to
evaluate knowledge of dental students of Hormozgan University
of Medical Sciences. This was a cross sectional study carried
out among all of the dental students of Hormozgan University of
Medical Sciences (HUMS) in 2012-2013. A questionnaire
containing demographic question (age, gender) and 20 questions
(7 general questions and 13 specialized questions) about
knowledge toward HIV/AIDS was distributed among the
participants. Data was analyzed by frequency, one way t-test,
chi-square and spearman correlation test using the SPSS (V.19).
The significant level was set as < 0.05. Totally 78 student
participated in this study. The mean age of participants was
21.44 ± 2.54. Forty five (57.7%) were preclinical students. The
mean score of questionnaires was 52.38 ± 4. This score among
preclinical students was 52.28 ± 4.2 and in clinical students
was 52.92 ± 3.4.There was no significant difference between
total scores of respondents among clinical and preclinical
students (P > 0.05). Only two students (2.5%) got below 41
points (poor knowledge). Fifteen students had achieved between
41 to 50 points (moderate knowledge) and the remains (N = 61, p
= 78.2%) achieved higher than 51 points (good knowledge).
Although, the knowledge of dental students was high, they
didn’t have enough knowledge about post exposure prophylaxis
which is an important subject and any oral health worker may
experience it in their professional life. Educating health care
workers especially dental students regarding the prophylaxis
strategies in preclinical course is recommended.

Modeling Integrative and Derivative Systems in Bond
Graph Modeling and using it in Adaptive Control
Majid Habibi1, Mahdi
Ghane 2, Alireza B. Novinzadeh3
mahdighane28@gmail.com
Abstract:
In this paper a method for
modeling integrator and derivative of effort and flow variables
in a bond graph model is offered. In many dynamical systems
there is a need to get the value of integral and derivative of
a variable, for example in PID controller in a closed-loop
controlled system. Here the way of implementing individual
integrator and derivative elements using bond graph
possibilities is presented. In this work the variables that
their integral or derivative values are taken, are presented in
the form of effort or flow variables as two fundamental
variables of the system. This will allow us to model many
systems by bond graph that they couldn’t be modeled before. In
continue, its usage in some examples is presented. For examples
classic closed-loop controlled systems by PID controller are
used. Then the state equations, ruled over the full closed-loop
system, are extracted from the model. It can be seen that the
PID gains are appeared in the state equations. This
specification is used in adaptive control by gain scheduling
approach, and by these equations; the PID gains, required for
attaining the desired system behavior along the time, are
obtained. Using this method the PID gains for gain scheduling approach
for a nonlinear plant can be obtained with no need to
linearizing it. Furthermore this approach has the advantage of
capability of modeling hybrid systems consist of various
domains such as mechanical, electrical, hydraulic, magnetic and
…, and designing controller for them. It can be seen that in
this paper there are some novelties consist of modeling
integrator of effort and flow by bond graph, modeling
closed-loop controlled systems entirely by bond graph and also
investigating adaptive control by bond graph.

Abstract: Existing evidence about the
indicators of board performance evaluation in the healthcare
organizations demonstrated that a comprehensive review of literature
is still required to broaden our understanding of this topic.
This review aimed to add to the literature on performance
evaluation of the boards by providing a summary of
literature-based perspectives. Using a systematic search
strategy, ten eligible papers were entered into the review. Thirty-five indicators of board performance evaluation in the
healthcare organizations were identified in these papers. We
illustrated more about these indicators in the paper. Our results showed a
gap in the literature with respect to the performance
evaluation of the health boards. Given the unique context of
the health organizations, it is suggested that more research need
to be done in order to understand the indicators of the board
performance evaluation.

Abstract: This study aims to determine
the digestive effect of garlic (Allium sativum L.) on
acid secretion and stomach pepsin. In this study two groups of
12 wistar rats were tracheostomized, laparatomized,
gastrodeodonostomized, and then 100mg/kg of garlic methanol
extract dissolved in 9% saline was introduced into their
stomach. The stomach secretions then washed out in first base,
second base, vagus-stimulated conditions and reverse to base.
The vagus nerves of both side of the neck released from carotid
sheet and stimulated with 15 millivolts, frequency of 4 Hz and
1 millisecond wide. The gastric acid amounts were measured by
titrometry and gastric pepsin amounts were measured by Anson
technique. The study showed that garlic
extract increased the level of acid secretion in all stages and
pepsin secretion in first base, vagus stimulated conditions,
and reverse to base significantly compared to the control group
(P<0.05). The vagus-stimulated conditions caused a
significant increase in gastric acid and pepsin secreting
compared to the first base (P<0.05). The level of gastric acid and
pepsin secretion did not show a relationship between the rats
and their gender. In conclusion using this plant and its other
products is forbidden for those patients suffering from
indigestion due to acid or pepsin increase. So patients
suffering from gastritis, duodecimal and ulcer are not allowed
to use this plant in their daily diet.

Abstract: Hexapod Robots gives us the ability
to study walking robots without facing problems such as
stability in many aspects. It has a great deal of flexibility
in movement even if a leg becomes malfunctioned. Radially
symmetric (hexagonal) hexapods have more flexibility in
movement than rectangular leg alignments. Because of symmetry
they can move in any direction and time efficiently. Inverse
kinematic problem of this kind of hexapods is solved through a
modular mobile view considering six degrees of freedom for the
trunk. Then typical tripod and wave gaits are analyzed and
simulated through the presented formulation. In Reinforcement
Learning algorithm for walking it is important how to make
reward signal with respect to robot’s actions and states. A
fuzzy approach is presented and analyzed to generate reward
signals. It is shown that the presented fuzzy system generates
more considerable accurate rewards with better performance than
functional rewards which are used in walking learning
problems.

Abstract: Worldwide
Interoperability of Microwave Access (WiMAX) has potential
success in its line-of-sight (LOS) and non line-of-sight (NLOS)
conditions which operating below 11 GHz frequency. There are
going to be a surge all over the world for the deployment of
WiMAX networks. Estimation of path loss is very important in
initial deployment of wireless network and cell planning. The
wireless channel is modeled as a sum of paths. The wireless
channel is modeled as a sum of paths. When the paths represent
reflections, the path-strengths depend on the distances
traveled and on the reflection coefficients.

Abstract: Mechanical Activation Assisted
Self-Propagating High-Temperature Synthesis (MASHS), as an
advanced method in early decades is used for synthesis of
advanced engineering compounds and composites; so,
preparation of ceramic composites reinforced by second phase by
this process is focused in different industries because of
their unique thermal, erosion, corrosion, chemical, mechanical
and electrical properties. In this research the influences of
type and pressure of synthesis environment and preheating of
samples on synthesis characteristics and structure of produced
ZrB2-ZrC composite were surveyed. Raw materials
powder were mixed stoichiometrically and ball milled for 10
hours according to 2ZrO2+B2O3+C+7Mg=ZrB2+ZrC+7MgO
chemical equation. Then influences of type and atmosphere of synthesis
environments including relative vacuum, Argon gas in
atmospheric pressure and pressurized Argon gas and also
preheating of samples conditions on combustion reaction,
synthesized phases and achieved product structure were studied.
Synthesized samples were analyzed by XRD and SEM methods for
inspecting of produced phases and achieved structures. XRD
patterns revealed that by changing combustion environment from
relative vacuum to pressurized atmosphere, process is more
controllable for producing desirable phases but from structural
point of view, only preheated sample was synthesized in the
form of nanocomposite.

Abstract: Apples
are one of the oldest fruits known to mankind and have been
cultivated for many years. In order to investigate the effect
of foliar application of amino calcium on Golden Delicious
apple trees a randomized complete block design with four
repetitions was conducted in the city Abadeh, Fars Province,
southern Iran. Apple trees were
sprayed with different concentrations (0, 2.5, 5.0, and 7.5
mg/l) of amino calcium. After spraying the
trees mature fruits were harvested and stored in cold storage
houses for 3 months. After this period, traits such as amount
of calcium, fruit weight, fruit firmness, and decay were
assessed at the horticultural laboratory of Jahrom Azad
University. We found that foliar application of amino calcium
delayed and decreased the amount of fruit decay during storage.
Fruit firmness was highest in apples that were sprayed with 7.5
mg/l amino calcium. Moreover, fruits that were sprayed with
7.5 and 5 mg/l amino calcium had lower weight reduction
compared with fruits that were sprayed with other
concentrations of amino calcium. We found no significant
difference between different concentrations of amino calcium
with respect to calcium levels.

percentage, fruit weight, fruit firmness and decay of tissue
were assessed at the horticultural laboratory of Jahrom Azad
University. The results showed
that the percentage of fruit decay in the control treatment was
more than the other treatments. The foliar application of
calcium chelate on apple trees considerably reduced fruit decay
during storage. The highest fruit firmness was related to apples that
were sprayed with chelated calcium at concentrations of 0.5 and
7.5 mg/l. Moreover, the fruits sprayed
with the control treatment had the highest percentage of weight
loss. Spraying fruit trees
with chelated calcium led to less weight loss during storage.
The highest TSS percentage was related to apples treated with
7.5 mg/l chelated calcium.

Abstract:
In this study
geological-reservoir zonation has
been developed based on petrophysical logs and then
petrophysical parameters such as porosity, Water saturation and
NTG have been determined, evaluated and distributed throughout
of the field. Ilam Formation is subdivided
into three zones and two subzones. This zonation has been
extended and correlated to 4 nearby oil fields. In
order to populate the petrophysical
properties into the reservoir, structural model and 3-D
geocellular grid of the field has been constructed using
required geological and geophysical data. Each zone includes
some layers depending on the petrophysical/lithological
heterogeneity.
Based
on porosity and water saturation distribution, 2 rock types
including a good rock with a connate water saturation of 25%
and poor rock type with a connate water saturation of 50% have
been determined. Water saturation cut off has been determined
upon to modality of water saturation distribution plot and
based on intercept of 2 groups of sw frequencies, porosity cut
off was defined. PHIE=2% and Sw=76% have been identified as
cutoff criteria for NTG.
Petrophysical modeling has been
carried out using deterministic approach. Trend maps indicate that,
PHIE parameter
decreases from western toward eastern of the field, in all
zones.

Abstract: Bamdej Wetland with approximate
area of 4000 hectare in longitude of 48˚ E and latitude of 31˚N is situated
in southern west of Iran and 40 kilometer distance from
northern west of Ahvaz which is bordering Shavoor dam and
Village farms in north, Tavana channel in South, bamdej village
alongside Ahvaz-Andimeshk railway in east and Sadat Tavaher and
Sayed Jasem villages in west.
Shavoor Dam is in the river path of Shavoor which upon
crossing divided into two branches, Nahr lashkar and Nahr
khavoor. The aquatic
habitat of it which constitutes the main part of wetland has
provided appropriate and secure place to scatter the regional
animals particularly local and oviparous birds due to dominant
plants like cane and bulrush. Some parts among the wetland are
without the above coverage and it constitutes an aquatic open
place which is the proper place for feeding and resting aquatic
animals especially birds of passage. This research with the aim
of ecological evaluation in order to call Bamdej Wetland as
conservation place has been accomplished by using amended model
of Canada Environment Organization and rapid assessment;
consequently through two models, Bamdej Wetland achieved title
of conservation region.

Abstract: In bending buildings with large openings,
using beams as
load bearing
trusses is going to
be regarded as one of the main design
choices
due to the
economic
characteristics
as well as
being
simple to
connect to the
columns, being
lighter, open truss webs making better use of
space
providing
better facilities
for passing pipes,
which results
in stories with lower heights. Besides these advantages,
these structures
have important
disadvantages. Due
to the
way of building, the beams have more hardness and
resistance than columns. In such structures under earthquake, there is the possibility of
formation of
plastic hinge in
columns, which is not good according to engineers. Also, due to premature
buckling
of the web members under
horizontal reciprocating loads, a sharp drop
in the hysteresis
graph of these systems is observed which indicates a very low
energy absorption
in these systems and the hysteresis graph of these
systems is
unstable. Recently
a new type of
truss
is proposed
in which the plastic
hinge
location
is in
the central part
of truss and also their hysteresis graphs are more stable, these frames are named “special truss moment frames”. And also The different behavior of structures and heavy losses in four quakes; Northridge1994 (California),Kobe 1995) Japan,
Duzce (1999) Turkey, Chi-Chi (1999) Taiwan,
especially in the structures located on the path leading to the rupture, has made clearly
evident the significance of paying utmost attention to the near-fault records. This
study was
designed to compare
the seismic
behavior of
special
truss
moment
frames
at near-fault and far-fault
points. For
this purpose, a non-linear
static analysis
method and
non-linear
dynamic time
history is
used. 1, 3 and 5 storey structures, designed using Iran’s 2800
code and ubc97, have been studied in this research. Plastic
hinges are considered for these structures according to
FEMA-356 Criteria and selected records (Two horizontal
components and a vertical component) are based on the soil type
and the scale is 5% damping. Analysis was performed using the program
Sap2000 for all three structures.

Abstract: Sunlight is a clean energy
source taking advantages of which increasingly rises all over
the world. But, constructing solar power plants incurs huge
amounts of costs on the states. Therefore, designation and
production of appliances which their energies are supplied from
the sun can be an appropriate alternative to diffuse a solar
power plant in the people homes. Thus, construction,
implementation and maintenance costs are incurred to the
public. By the way, solar washing machine production idea was
formed. This washing machine of logic fuzzy type can wash 5kg
of clothes once in three days without any requirements for
electricity. Green color on its LCD indicates full charge
batteries and also these data are recognizable on a smart
phone. Energy stored in washing machine feed can be used to
turn on other facilities at home. For example, there are any
possibilities to turn on mixer, toaster or even cell phone and
lap top. In the events of power outage, the building can
operate as an independent energy source and guarantee home
lighting for more 20 hours. Just with the production of 200,000
solar washing machines more than 10,000Mw can be annularly
saved. This innovation has been recorded in Patent No. 63594 in
Patent and Trademark Office. [Saeed Zamani, Seyed Amin Hashemi. Designation

Abstract: This paper proceeds numerical
investigation on forced convective heat transfer of nanofluids
in laminar flow inside a mini-channel with circular
cross-section under constant heat flux boundary condition at
walls. Nanofluid contains CuO nanoparticles with diameter of 50
nanometer in water base fluid. At the entrance of channel,
profiles of uniform velocity & temperature prevail. In
order to obtain fully developed profiles, geometry of problem
considers as L/D = 100. Problem is solved by means of 4
different models, including Homogeneous and Dispersion models
in both of constant and variable thermophysical properties
through the finite-volume method. The temperature-dependent properties
was used for the first time in nanofluids dispersion model. It
was regarded in the presence of nanoparticles the heat transfer
coefficient will be increased to some considerable extent and
the heat transfer enhancement strongly depends on the volume
concentration of nanoparticles and Peclet number. Also,
comparison with experimental data and literatures’ correlations
is carried out which indicates the Dispersion model in both
cases is more precise and Homogeneous model (single phase)
underestimates the Nusselt number in constant thermo physical
properties.

Abstract: Objective: One of the main tasks of the
manager in the process of management is the leadership of the
organization. The present study aims to investigate the
attitude of Kermanshah University
of Medical Sciences staff towards the relationship between leadership
style and management
practices. Methods: This cross-sectional study (descriptive-analytical) was performed on the145
of the staff of
Kermanshah University of Medical
Sciences that were selected through the quota sampling –
random method. The study data were collected using two
questionnaires. Frequency distribution, standard deviation, and
percentages were used in order to
describe the data. Chi-square and
ANOVA were also used to analyze the data. Results: Among
the 145 subjects, 114 ones were selected to complete the
questionnaires. The study results
revealed a significant difference between the single and
married subjects' attitudes toward the leadership style. Attitudes also varied in
different age groups and this difference was statistically
significant. In this study, none of the subjects considered their managers' leadership
style as collaborative. The study findings revealed a statistically
significant relationship between leadership and management experience. Discussion:
None of the study
subjects mentioned collaborative leadership style for the
managers of Kermanshah
University of Medical
Sciences. This implies that managers are more attentive to the work environment and
identify the employees' tasks, but pay less
attention to the employees' participation. In
a specialized center,
collaborative management should replace
authoritarian leadership style.

Abstract: Recently, Very Large Eddy Simulation
approach has attracted a great deal of attention among
researchers. This approach can be thought of as an intermediate
approach in flow field filtering view point compared with
Direct Numerical Simulation and Reynolds-Averaged Navier-Stokes.
One famous method to this approach is Partially Averaged
Navier-Stokes. Early studies have demonstrated the capability
of this technique in flow prediction; however, this method
still needs to be evaluated under more flow conditions to
ensure its reliable performance. In this study, the performance
of PANS k-ω method in the simulation of turbulent flow
around a cylinder with square cross section close to a flat
surface, and at Reynolds number of 13200, has been evaluated.
Flow around a cylinder provides a good criterion to assess
capabilities of the proposed method. To do so, three different
filters have been evaluated dynamically and compared with each
other and Wilcox k-ω model. Results indicate that at such
a Reynolds number, method is as accurate as k-ω method.

Sciences, Sabzevar, Iran
Abstract: Background :Shorter length of
hospitalization of mothers will be helpful in economical,
social terms. Since last few decades oxcytocin infusion has
been used for induction of labor, but due to its complications,
new drugs need to be evaluated. The efficacy of misoprostol for
induction of labor is controversy. Therefore, the effects of
vaginal misoprostol on labor time and latent phase were
investigated. Materials and Methods: This
randomized clinical trial was conducted on 180 pregnant women
in 2009 in Mobini Hospital, Sabzevar, Iran. Oxytocin infusion
was used in one group and vaginal misoprostol (50mcg) was used
in the other one. Total duration of labor and latent phase
period in both groups were analyzed by T-student test. All tests
were assumed two-sided. Findings: Total duration
of labor for misoprostol was 10 hours and for oxytocin was 17
hours (p=0.01). Also latent period phase in misoprostol method
was lower than that of Oxytocin(6 hours Vs. 13 hours,
respectively) (p=0.01). Cesarean section rate was reported 11%
for vaginal misoprostol and 35% for Oxytocin (p=0.01). Conclusion:
using misoprostol compared with oxytocin, significantly
reduces both the latent phase and the total labor time. Also CS
rate is lower in the use of misoprostol compared oxytocin

Abstract: objectives: This study was undertaken to compare
post-operative outcomes associated with early oral feeding
versus late oral feeding after cesarean section. Materials
and Methods: In this randomized clinical trial, 140
pregnant women underwent elective cesarean section with
regional anesthesia were randomized in two groups. In the early
oral feeding group 2 hours after surgery and in the delayed
oral feeding group 8 hours after surgery a liquid diet began
for patients. If patients had appropriate tolerate to liquid
diet, regular diet began, gradually. The main outcomes for the
investigation were included duration of hospital stay, time to
return normal bowel function and post-operative
gastrointestinal complications. Results: time to return
of bowel movement (7.8±2.9 h vs. 11.7±5 h, p<0.0001) and time
to mobilization (10.7±7.7 h vs. 13.5±5.9 h, p: 0.015) were
occurred significantly earlier in early feeding than late
feeding group. We did not show any significant differences
between groups in the post-operative gastrointestinal
complications. Conclusion: early oral feeding given 2
hours after cesarean section has positive impact to reduce time
to return normal bowel function with no significant effect on
gastrointestinal complications.

Abstract: In this investigated the
concentration of the heavy metals such as lead, mercury,
cadmium, nickel and arsenic in the liver tissue of fish Pomadasys Kaakan caught from the Persian Gulf were
studied. Determine the concentrations of heavy metals in liver
of fish samples were prepared by atomic absorption model

=
0.60(ppm), 4. Hg
=
0.05(ppm).
Accumulation
of heavy metals, lead and nickel exceeded the standard for
human consumption was determined that the cause can be
attributed to environmental pollution and type of feeding fish.
One of the most fundamental difficulties is accumulated heavy
metals in the body which cannot metabolize them. The heavy
metals in the some part of body such as in other tissues fat,
muscle and bones joints and may accumulate the same conditions
which have caused numerous complications in the body. Heavy
metal salts and minerals as well as other alternatives are
needed in the body which is replaced with zinc and cadmium in
food. Also, taking the property of accumulation of heavy metals
in plants and enter the food chain, they will have doubled
their risks. The growing and extended industry and entered the
chemicals in water, soil and air, and contaminated the
environment is more likely to encounter human risks.

Abstract:
background: The complications such as fever, hematoma, urinary
tract infection and blood loss, are more frequent in emergent
ceasarean sections (C/S). We have conducted this study to compare
the frequency of complications in two types of C/S. Material
and Methods: This study conducted in Maternity Research
Center (MRC) and two educational hospitals; (Motazedi and Imam
Reza) in Kermanshah University of Medical Sciences, Kermanshah,
Iran. It conducted on 512
cases of C/S performed in two educational health care centers
(256 emergent and 256 elective C/S). Mothers with previous
history of background diseases (diabetes, hypertension, lupus,
history of twin birth, and history of corticosteroid therapy,
microbial and fungal infections) during pregnancy and delivery
were excluded from the study. For comparing the complications
between two groups we used the, Chi square and Fisher’s exact
tests. Results: Our findings indicated that 40.6% of
emergent C/S were performed due to disproportionate fetal head
to maternal pelvic and 62.1% of elective C/S were performed due
to previous C/Ss. APGAR scores of 1-6 were observed in first
minute of 4.3% and fifth minute of 1.6% of neonates delivered
with emergent C/S, and 3.5% and 0.8% in elective C/S
respectively. In general, 12.5% of emergent C/S and 6.6% of
elective C/Ss developed complications. Discussions: Our
study indicates the C/S complications for both mother and
neonate, and these complications are more frequently observed
with emergent C/S.

Abstract: In today’s rapidly changing
work life, organizational justice has become increasingly
important to employees. Prior research shows that Perceived
justice is associated with people feelings and behaviors in
social interactions. In this article we examine the
contribution of distributive, procedural and interactional
justice to employee organizational citizenship behavior (OCB).
Data was collected through Rego and Cunha (2006) organizational
justice and Podsakoff (2000) OCB questionnaires from 102
employees (67 male and 35 female) of Khorasan Razavi province
sport and youth organization. The findings of the study
revealed that perceived organizational justice and its
components have significant impact on employees’ OCB. Moreover,
no differences were found between male and female employees
regarding these variables. Interactional justice was found to
be the strongest predictor of OCB.

Abstract: Organizational
citizenship behavior (OCB) has received considerable attention
in recent years. It has been studied as behavioral outcome of
employees’ motivation in organizations. However, the present
study sought to discern the relationship between employees’
perception of empowerment with OCB as voluntary acts beyond the
role specification in 75 employees of sport and youth organization
of khorasan Razavi province. Data was collected through
organizational citizenship behavior and employees’ perception
of empowerment questionnaires. Both scales were adapted into
farsi. Statistical analysis of the study reveald that mean
scores of employees’ perception of empowerment and OCB were
low. There was a significant relationship between employees’
perception of empowerment and its subscales with OCB (p <
0/05), a stepwise multiple regression analysis showed that
meaningfullness and competence were the strongest predictors of
OCB.

Continuum of evolution and development in the world and the achievements
and results which are Come from it, integrated with the
people’s life in a way that, unnoticiny to it, will create some
main interferences in Society, People’s welfare and peace. So
the Key role of modern information and Communication technologies
in economical, Social and Political fields are
unignorable. Parallel to extended evolution of technology and
variable information of world, one of the most important
arguments in general society of technology and developing of
information is electronic government issue. The government which
in it, the use of internet by governmental organizations for
giving services and information to people, Companies and other
government organizations, is as unignorable necessity and
therefore all the citizens, trade Companies, other government
organizations and government office-workers be able to access
to information and government services by a web-site in
internet, without any time and place limitation. In current
article the basis of electronic government and the importance
of its creation in information and communication technologies
era, will be studied, for this at first we will state the
different interpretations of electronic government, its history,
and then we discuss about the different point of view of electronic
government phenomenon, and following it we will mention the
usable symbols in electronic government, united nations report
about the electronic government establishing, advantages of
electronic governments, necessities of accomplishing the
electronic government, and Pinally the problems and obstacles
that can be seen in Iran in achieving the electronic
government, and also the solutions that are advised in this
field..

Abstract: Today, many advances
have been made in recognition and treatment of viral diseases, although
the nature of viruses, prevention, and treatment of some of
them has remained not very clear. Many unknown viruses in short
time have shown detrimental effects on human health,
while the number of people who suffering
from viral diseases are increased. In this paper, we introduce
a new treatment for viral disease by injecting the electrical
current into the viral affected environments. In this method,
low electrical currents with a set of different parameters are
injected to the viruses in laboratory environment, before
transmitting them to the cellular environment. Then we have investigated impact of
the currents that injected on viruses. During the experiments
it was observed that electrical current injection can
demobilize the natural viruses. Also, several parameters were
tested for electrical currents, and we have tried to find set
of parameters not only with the greatest impact on viruses, but
also with the least damage on living cells. Finally, we
concluded that in case of viral diseases, typical treatments
can potentially be alternated by electrical current injection.

Abstract. Due to the
extension of attacks to computer networks in the current
decade, it is crucial to secure the networks in an appropriate
and effective way. One
solution is to have a host that supervises the situation for
all the computers in the network and makes decision regarding
possible attacks. This method is not effective in recently
developed networks due to their large extension and high speed.
We propose a new distributed intrusion detection system that is
based on cooperative agents (‘DIDCA’). Agents are grouped into
subsets of agents that are in connection with a leader on top.
Leaders of different subsets communicate together to share all
the information throughout the network. We simulated our method
using DARPA 1999 database and compared it with Snort. Our
results showed that our method achieved a better performance.

power systems at the distribution level regularly. The power
demand is increasing and it can be fulfilled by use of
renewable energy sources like solar energy. This paper
discusses the using of Photovoltaic power plant as a DG in Iran
with considering environmental conditions. The main objective
of this paper is to specify the adjustment coefficients for
real maximum output power of Photovoltaic panels in different
parts of Iran. In order to scrutinizing the effect of PV system
placement as a DG in redial distribution system, in most
appropriate part of Iran according to obtained adjustment coefficients,
a 12-node radial distribution network is simulated with
Digsilent software. Reducing in power loss, considering solar
irradiance and temperature in different months of a year, is
obtained.

Abstract: This research investigated the physical properties
of Jatropha oil to determine its viability as a clean and
renewable source of lubricant oil. The study was performed
using a four-ball tribotester, CCD camera, scanning electron
microscope, digital microscope and viscosity meter. The
experiment was conducted using different temperatures (55, 95
and 125°C) and loads (200, 400, and 600 N). The experiment was
performed under the American Society for Testing and Materials
(ASTM), number D 4172.The data included the evaluation of
anti-wear, anti-friction, coefficient of friction, wear scar
diameter and viscosity of Jatropha oil. All results of this
research were compared to findings regarding hydraulic oil as a
commercial mineral oil- based lubricant to evaluate lubricant
ability. The results showed that, using various temperatures
and loads, Jatropha oil had a higher lubricant ability compared
to hydraulic mineral oil.

Abstract: This paper deals with a robust
economic-statistical design of control chart, in which the
input parameters are expressed as intervals. The design
procedure relies on finding the best design parameter set based
on the minimax criterion for risks. Genetic algorithm (GA) has
been used as a search tool to find the best design (input)
parameters with which the control chart has to be designed. The proposed method minimizes the risk of
not knowing the true parameters to be used in the design, and
is robust to the true parameter values. A numerical
example is used to illustrate the performance of the proposed
economic-statistical design of the control chart.

Abstract: In the recent years the power system is changing
and distributed generation (DG) units are used in power systems
at the distribution level regularly. The power demand is
increasing and it can be fulfilled by use of renewable energy
sources like solar energy. This paper discusses the using of
Photovoltaic power plant as a DG in distrusted network and its
effect on transient stability. In order to scrutinizing the
effect of PV system as a DG in redial distribution system, 3
IEEE standard test systems are simulated with Dig SILENT
software. In all 3 networks a short circuit fault is taken and
the effect of that is analyzed in 2 modes; first with
synchronous generators (SG) and second with Photovoltaic (PV)
power plant and the results are compared. Comparing the results
shows that in all 3 networks PV power plant work could save the
stability in active power and voltage without using any extra devices.

Abstract: This paper presents using Imperialist Competitive
Algorithm (ICA) and its application to a least-cost Generation
expansion planning (GEP) problem. Least-cost GEP problem is
concerned with a highly constrained nonlinear dynamic
optimization problem that can only be fully solved by complete
enumeration, a process which is computationally impossible in a
real-world GEP problem. In this paper, Imperialist Competitive
algorithm incorporating a stochastic technique and random
initial population scheme is developed to provide a faster
search mechanism. The main advantage of the ICA approach is
that the “curse of dimensionality” and a local optimal trap
inherent in mathematical programming methods can be
simultaneously overcome. The ICA approach is applied to two
test systems, one with 15 existing power plants, 5 types of
candidate plants and a 14-year planning period, and the other,
a practical long-term system with a 24-year planning period.

Abstract: Deregulation in the electricity
industry leads to new challenges in Generation Expansion
Planning (GEP), due to the competition among the Generation
Companies (GENCOs) and opposing objectives of GENCOs and policy
makers. This paper presents the GEP problem in competitive
environment and applies the Imperialist Competitive Algorithm
(ICA) to solve this problem. The objective of each GENCO is
maximization of its profit while the regulatory body is
concerned with market and system stabilization trough providing
the appropriate signals to investors to avoid the over/under
investment. Other objectives of the regulatory body are
optimization of generation capacity, maintaining system and
national security and maximization of the social welfare. In
order to model the competition between the GENCOs and opposing
objectives in this problem, the GEP problem is modeled as a
Cournot game with Nash equilibrium. The GEP problem is solved
iteratively by self-optimizing of each GENCO using ICA and
satisfying the regulatory body in Cournot model. The proposed
algorithm is tested on a simple case and the results are
compared with those drawn in previous works. The obtained
results demonstrate the effectiveness of the proposed ICA-based
method.

Abstract: Administration of amitriptyline, a most commonly
used tricyclic antidepressant, is associated with anticholinergic
side effects and rare but severe hepatotoxicity. It supposed
that the intermediated metabolites of amitriptyline produced by
CYP450 involved in hepatotoxicity but the exact mechanisms
involved in hepatotoxicity are unknown. The aim of this study
was to determine the mechanism of hepatotoxicity induced by
amitriptyline and protective role of taurine in an in vitro model
of isolated rat hepatocytes. Markers such as cell
viability, reactive oxygen species (ROS) formation, lipid
peroxidation, mitochondrial membrane potential, and hepatocytes
glutathione content were evaluated every 60 minutes for 180
minutes. Our results showed that amitriptyline resulted in
cytotoxicity characterized by the reduction in cell viability,
an increase in ROS formation and lipid peroxidation,
mitochondrial membrane potential collapse, and a reduction in
cellular glutathione content. Our
finding showed administration of taurine (1mM) effectively
reduced the toxic effects of amitriptyline in isolated rat
hepatocytes.

Abstract: Nowadays, software organizations
spend much time and resources to analyze and investigate
software requirements. Thus some factors like the need to fast
software delivery with a high quality, the superiority in
competition with other companies, satisfying customers, considering
the market dynamics, the change of customer needs, and
addressing market challenges have finally led to develop agile
methods as well as the requirements issue becomes one of the
most important topics. As it is time consuming to define needs
at one stage and impossible to spend much time in order to
determine requirements completely using traditional ways in
agile methods, screening and some other ways are required to
identify needs in the agile method. This paper is aimed to
study requirements and identify strategies of useful and
useless ones to develop the software via agile methods because
of the need to the software and different competitions between
developers in rapid software providing perfect and with a high
quality.

Abstract: An attacker has to ‘scan’
susceptible points of a network before attacking. There are
several methods of detection of such behavior which are mostly
based on thresholding. As the performance of these methods is
highly dependent on the value of threshold, it is crucial to
adjust this value appropriately. This adjustment is not always
trivial. In this study we proposed a new method to optimize the
parameters of the system using genetic algorithms (GA) based on
network flows. Subsequently we compared our method with Snort.
The results showed a superior performance as measured by the
sensitivity index of d’.

Abstract: Because of
many advantages of self-propagating high-temperature synthesis,
this method is used increasingly for advanced compounds and
composite materials production. ZrB2-ZrC composite
has unique characteristics, so its synthesis with the least
undesirable phases is an important problem for producing this
composite. In this research, synthesis of this composite by
metallic element as a reductant agent by SHS is done
successfully, but elimination of undesirable compounds are
costly and difficult. In order to prevent creating these
compounds, replacement of metallic element by MASHS process,
thermodynamically and practically points of view were studied.
According to used mechanical activation conditions, synthesis
of desirable composite was not occurred. For this process
replacement, the initiating activation energy subject was
discussed for achieved results.

Abstract. Computers have been used in education for more
than three decades. Computer-based training (CBT) and
computer-aided instruction (CAI) were the first such systems
deployed as an attempt to teach using computers. Computer-based
training has two important branches 1) E-Learning System and 2)
Intelligent Tutoring Systems. Both systems have strengths and
weaknesses. It is well known that e learning Systems not
provide the same kind of individualised attention that a
student would receive from a human tutor, as they do not reason
about the domain and the learner. This has prompted research in
the field of intelligent tutoring systems (ITSs). ITSs achieve
their intelligence by representing pedagogical decisions about
how to teach as well as information about the learner. They have been shown to be highly effective at increasing students' performance and motivation
The goals of learning no longer were solely based on acquiring
skills and facts but started to include the strategies and process used by the student
to reach mastery of a
knowledge domain.
This paper reviews ITSs architectures.

Abstract. The application and development of e learning and
distance education via the Internet and Intelligent Tutoring
Systems (ITS) has been growing inexorably, in recent years.
Both systems have strengths and weaknesses. Intelligent
Tutoring Systems are typically domain septic and rely on
concise knowledge modelling and learner modelling. The goal of
the research in the area of Intelligent Tutoring Systems is to
build computer-based tutors that achieve the effects of
learning individually with a human tutor, while E-learning
systems suffer from
defects mainly related to the relative absence of the teacher and, therefore, the difficulty of adapting teaching to the level and behaviour of
the learner. This paper provides possibilities for convergence
of these two areas, and describes two of our experiences in
providing an Intelligent Tutoring Systems style approach to
eLearning systems.

uses sunlight, seawater and air to provide freshwater and
cooled and humid air, so that in addition to provide the water
required for greenhouse, supply more sustainable environmental
condition from cultivation of crops in arid coastal regions. In
this system ambient air is passed through the two evaporative
cooling pads, which plant growth area is placed between those
pads, by fans that placed end of the building, and then
returned taking humidity on the tube-and-fin condenser. In
order to decrease the entrance heating load to the plants, use
pipe arrays to provide shade. This paper tries to describe
simulation the Seawater Greenhouse considering condition of the
Bandar Abbas City in IRAN. Different cycles of Sea water
greenhouse, including 6 arrangements, was modeled and obtained

Abstract:
The
genus of Prangos consists of about 30
species, 15 of which are growing wildly in many regions of
Iran. Prangos ferulacea (L.) Lindl. with the common
Persian name of "Jashir" is a perennial and
aromatic plant from Apiaceae (Umbelliferae) family which is
native to the mountains of southern Iran. P. ferulacea
has been used in folk medicine as emulient, carminative, tonic,
sedative, antiflatulent, anti-helmintic, antibacterial,
antispasmodic, and antidiabetic agents. Monoterpenes,
sesquiterpenes, coumarines, flavonoids, alkaloids, tannins,
saponins, and terpenoids are some important
compounds identified in this plant. Previous researches
indicated that antioxidant properties of this plant were higher
than α-tocopherole (vitamin E) and the main compounds of P.
ferulacea in different growth stages were monoterpenes,
specially α-pinene, and β-pinene. The present article
aimed to examine the extensive pharmacologic active factors
existing in this plant and its potential efficacy mechanisms to
be used in medical and pharmacological works in the future.

Sciences (SKUMS). Methods: For this
descriptive-analytical study, educational profiles of all health graduates of SKUMS
between 1365-86 were examined and the data was gathered
through a researcher-developed checklist and phone calls. Data
analysis was performed by SPSS 16 using Cox regression. Findings:
From 398 respondents of the study with a mean age of 22.2 ±
2.25 (range: 20-39), 140 (35.2%) were male and 206 (51.8%) had
been admitted to higher education. According to Cox regression,
some factors, e.g. age, gender, marital status, residency, and
GPA associate, were significantly effective on continuing
studies and some others including associate course of study,
course period, and diploma GPA had no significant effect on the
chance of admission to higher education. Conclusion: Growing
older, one gradually enters other living arenas like marriage,
making continuing studies marginalized. Therefore, it could be
assumed that the factors influencing continuing studies should
be considered a whole, i.e., the circumstances should be
prepared to facilitate continuing studies before growing older
and facing consequent life issues.

Abstract: Background: Accountability
in hospitals is similar to reverse engineering
in industrial design. So that neglected of
this may be lead to the output in the lowest category. This study design has been done to improve accountability
in the teaching hospital. Methods: This cross
- sectional study
has provided a new model
by using the previous model in 2011. This
study was performed on 210 cases of hospital staff and patients, in Imam Reza hospital of Kermanshah.
Data was collected by validated and reliable self made
questionnaire. The questionnaire had eight dimensions (ethical,
political, cultural, operational, structural, financial,
informational, and legal) and 31question. Data
analysis was performed
by using Pearson
Correlation test and
t-test by SPSS version 19.
Results: The mean score of accountability in Imam Reza
hospital was 3.25 ± 0.74. Highest score
was related to the
political dimension (3.68 ± 0.77) and
the lowest score
was related to cultural
dimension (2.85 ± 0.83). By using
the Expert Panel, final
pattern traced and verified. Conclusion:
According to the moderate state in this hospital, where
is the sensitivity of service provider, this
situation did
not seem too satisfactory. Therefore, in order to validate the hospital propose that accountability unit is deployed
compliance with this dimension and other aspects in hospitals.

Abstract: Increasing
development of Combined Heat and Power (CHP) system
applications in residential consumption has been resulted in a
competitive market between generating power by these units and
purchasing it from national grid. In Iran, on account of huge
energy subsidies allocations, there has been no opportunity for
the mentioned units to compete with the conventional practice
of purchasing electricity from national grid up to now.
Considering recent government policies, to remove the subsidy
related to energy carriers, this paper intends to evaluate the
applications of CHP units in residential buildings from
economical point of view. For this, HOMER software has been
utilized to evaluate the CHP unit placements as well as their
utilization manner in order to minimize total energy costs for
residential consumers. The results indicate that in the case of
removing energy subsidies, the installation of such units will
be economically quite cost-effective.

Dysplasia (dys) and Gastric Carcinoma through the expression of
biomarkers of lymphocytes surrounding the lesions and their
possible application in the differentiation diagnosis of these
lesions. Material and Method: paraffin blocks related to
19 RH samples, 5 In.dys samples, 20 Dys samples and 15 carcinoma
samples were selected according to Padvoa Classification
criteria and IHC staining was performed on them for markers by
Envision technique; then, the differences between them were
analyzed in terms of risk markers. Findings: the
expression of CD4 marker in lymphocytes surrounding RH, In. dys,
Dys and carcinoma is 15, 21, 20 and 31 percent respectively; its
expression has no significant difference between In.dys and Dys.
But in general, a significant increase has been observed from RH
towards carcinoma. The expression of CD8 marker in lymphocytes
surrounding RH, In.dys, Dys and carcinoma is 27.4, 28.2, 18.4
and 22.2 percent respectively; Dys and In. dys had no significant
difference from each other. But in the progression of lesions
from RH towards carcinoma, a significant reduction was observed.
The expression of CD20 marker in lymphocytes surrounding RH,
In.dys, Dys and carcinoma is 27, 21, 19 and 14 percent
respectively; like CD8, a significant reduction was observed
from RH towards carcinoma. And the expression of CD56 is 11, 14,
10 and 12 percent respectively with no significant difference.
Conclusion: from RH towards carcinoma, the expression of
CD4 had an increase; the expression of CD8 and CD 20 had a
significant reduction and CD56 had no significant difference in
the progression of lesions.

Abstract:
The main aim of this study is to conduct the period of training
of active athletes competitions blood lipids (triglycerides,
cholesterol) and lipoprotein (HDL-C, LDL-C and VLDL) changes in
levels of malondialdehyde (MDA) and glutathione peroxides (GPX)
levels and to investigate the related effects in this regard.
The research group is consisted of
twenty volunteer athletes
participated in seasonal training within the program of training
sessions on a regular basis. Blood samples were taken at the end
of the season and before the competition season and plasma MDA,
GPX serum, blood lipids and lipoproteins were analyzed in this
case. According to the working group cases for the comparison of
pre-and post-test analysis of HDL-C (p <0.05) and GPX (p <0.01),
significantly differences in the related research were found.
Competition of post-MDA levels in serum TG, VLDL and p <0.01 was
showed difference between the levels. As a result, the working
group making a regular practice of lipid peroxidation did not
increase due to the adaptation of MDA in understanding the
changes. GPX's recent emergence is due to the cause of low
measurements and the fact that athletes could be considered as
having an adequate antioxidant defense system.

Abstract:
This paper reflects briefly
political, social and economical stature of France of the 17th
and 18th centuries. In its pursuit, it begins showing
us how the Catholic Church played a major political role in
political and spiritual developments of the country after
starting to encounter new emerged religious groups such as
Islam, Mazdaism and Manichaeism. A chronological glimpse on
papal bulls and how they wish to be regarded as the ultimate
authority, in a time of superstitious interpretations of
Catholicism and its Vulgarization, will be discussed. Babylonian
Captivity and Pope Boniface VIII’s failure to draw the Catholic
Church out from the sidelines are discussed in this section of
the paper. Later, France colonizing attempts are introduced and
how Captain Jack began a legacy of plunder and usurpation for
the French merchants in parts of the new word, known as Canada
nowadays. Cardinal Richelieu’s, Jean-Baptiste Colbert’s and
Louis XIV’s attempts in promoting the French colonies in India,
North and South America and the African states will be discussed
briefly.

Abstract: In this
paper, statistical analysis is made
use of to develop a fault dictionary. A three phase single level
Voltage Source Inverter (VSI) circuit is being chosen as Circuit
Under Test (CUT). The output of the CUT is subjected to wavelet
transform. Based on the transform coefficients for the fault
free circuit as well as simulated faults for the CUT, fault
dictionary has been framed. Fault dictionary is being generated
by extracting the standard deviation (from statistical analysis)
of the transform coefficients. Extracted parameters are utilized
to develop the fault dictionary, which is later used for fault
identification. The method has been validated using a single
phase multilevel inverter circuit.

Abstract:
Teachers and Lecturers stipulates
that teachers must possess academic qualifications, their
educational background must be relevant to the subjects they
teach and they must possess competencies which are necessary for
teaching. In relation to this requirement the present study
intended to investigate the pedagogic competencies of future

The development
challenges give implications towards the important roles of
education to produce qualified human resources.
In today's rapidly developing
technological society, there has been increasing demand for
highly skilled and professionally qualified experts. The data
were collected in 2011 by using questionnaires, focused group
discussion. The results of data analysis show that the
competencies of future specialists are not satisfactory yet. The teachers have relatively good competencies in making the
lesson plans since their lesson plans have been based on the
standard competencies and elaborated indicators. However, in
terms of implementing the lesson plans, it is clear that they
have not implemented competency-based teaching learning process
yet. The teachers still dominated the class, and did not provide
the students with sufficient opportunities to use the language.
In terms of assessment, the teachers still implemented
conventional paradigm of testing and did not understand how to
apply competency based assessment.

Abstract:
This article
provides the methodology of determining the living standard of
the population of a country. By
using
this methodology
one can
make a comparative
analysis of
the standard of living
in the territorial
scale, i.e.,
comparing the
standards of living
in different countries.
A
comparative
analysis of the
standard of living in
a
time interval
can also be made,
i.e., comparing the
standards of living
in
different times.
The methodology of determining the population living standard
examines 110 component indices and the 14 derivative indices
reached on the basis of indicators characterizing the
comprehensive situation of the population.
On this basis
the generalizing
index is determined
by the index of
the standard of living
of the population.
Furthermore, in the methodology composed of the values of the
final index, the standard of living of the
population
is divided
into the categories of rich, sustainable, poor, and pauper levels.

Abstract:
The article determines
applicability of investigation into simulation of fire
engineering processes in energy devices (boilers, furnaces,
internal combustion engines and others) aiming at their
optimization and increase in reliability. Survey has
demonstrated that the procedures of calculation of such devices
are not widely available. Development of procedure of
engineering design and verification is necessary for further
advance of production of oscillating combustion apparatuses. The
author has revealed main problems of development of calculation
procedure of energy devices based on oscillating fuel
combustion. In order to decrease probability of defects within
operation and heterogeneous distribution of thermal loading for
metal structure the author proposes mathematical model of
hydrothermal parameters in dimensionless form, which makes it
possible at the designing stage to determine reliability and
efficiency of operation of such devices of various applications
based on the principle of auto-oscillating fuel combustion. On
the basis of simulation results recommendations are presented
aimed at improvement of designing of pulse combustion boilers.
The results have been delivered and implemented at a plant where
such boiler units are produced. Practical value of the results
is in development of procedure which facilitates analysis of
hydrothermal processes in elements of commercial heat and power
plants based on oscillating fuel combustion.

Abstract:
In this
article the author analyzes the Criminal Code of the Republic of
Kazakhstan and deals the interrelation between crime and
punishment.
Moreover, studies the
types of criminal penalties and the grounds for release from
punishment. Noting such kind of punishment as imprisonment the
author puts forward an alternative to imprisonment, dwelling on
problems and prospects. The author considers imprisonment as the
result of the courts application of the criminal law and
proposes further improvement of criminal legislation in the form
of offers to the project of a new Criminal Code of the Republic
of Kazakhstan. On this basis, decline in the prison population
and the prisons maintaining costs is projected as well as
stabilization of the crime situation and reduce in the number of
offenses in the country. In the conducted research the common
ground between national criminal law systems, especially those
of the CIS countries has been sought, so as to contribute to the
enrichment of theoretical thought, and for dialogue between the
scientific community of the country and the government. This is
definitely not a complete solution, but an attempt to get closer
to it.

Abstract:
Creeping flow of an
incompressible second grade fluid in a channel of varying width
bounded below by a porous bed is solved using three approximate
methods based on three different geometrical configurations.
Expressions for velocity and pressure gradient are calculated
for each method. Weight functions are calculated for all three
methods and are evaluated for different values porous layer
parameter. It is observed
that
the weight functions are
influenced by porous layer parameter. The obtained results are
applied to idealized stenosis geometry and resistance to the
flow and shear stress are calculated. It is noticed that as we
increase the value of porous layer parameter resistance to the
flow in the stenosed region decreases as expected. However with
increasing the values of
porous layer parameter
and non-Newtonian parameter,
the shear stress increases in stenosed region. Previous
published results are obtained as special case to current study.

Abstract:
The article is devoted to the
complex research of modern methods of teaching reading. The
characteristic features of processes of teaching and reading
Kazakhstanis on the basis of the state program "Reading
Kazakhstan" are analyzed in the article. Reading becomes
relevant for scientific knowledge and intellectual development
of a personality. Reading forms the consciousness of the person
and the foundations of world outlook, intellectual development
and acquires professional skills in education. Special attention
is paid to the psychological study of the relationship
peculiarities of the personality development and training
reading. There is an attempt of the development of theoretical,
methodological, and psychological foundations of ownership and
improvement of skills in the techniques of speed reading and
development of personality of the Republic of Kazakhstan.
Multicenter studies of the problems of new reading technologies
are summarized. The article considers some results of
investigations aimed at the improvement of peripheral visual
perception of the personality on the basis of teaching reading.
On the basis of the research conducted by the author obtained
data can be used for analysis to improve skills in the
techniques of speed reading (skimming). The developed program
and the data allow us to recommend the effectiveness and
duration of training as an effective training method for
development of speed reading skills. Techniques and trainings to
improve skills in the techniques of speed reading are offered in
the article. It is concluded that the formation of the ways of
understanding of the texts by learning to read activates the
development of speed reading skills and influences on the
intellectual development of a personality

Abstract:
The article deals with the
problematic issues related to livestock; determines the causes
of decline in production; identifies competition factors,
economic circumstances and state regulation of organizational
basis for the functioning of agriculture. In this connection,
the dynamics of change in gross production of milk and meat in
all categories of farms is shown as well as the role and
importance of households in livestock production, and ways of
overcoming the small scale of farms’ production. Restoration of
breeding, strengthening of the genetic potential of the animals
through livestock import, strengthening of food supply, as well
as state aid to modern farmers are studied as the main factors
for increasing the efficiency of production.
