Abstract:
The family Muridae is one of the
most ubiquitous invasive families all over the world and in
Egypt is particularly common and wide spread. Here we
investigated the degree of similarity and divergences between 8
species related to the family Muridae of common occurrence in
Egypt through molecular analysis of mitochondrial DNA (COI gene)
comparing between Acomys cahirinus, Mus musculus,
Rattus rattus, Rattus norvegicus, Albino Rattus
norvegicus, Gerbillus gerbillus and Gerbillus
pyramidum in Egypt. Our result showing a strong link between
Acomys cahirinus and genus Gerbillus than to genus Mus
and Rattus with high bootstrap support.

Abstract:
Biogas is a product
of anaerobic digestion of organic matter with microbial aid.
Nutrient based bacterial growth dynamics for cow dung and cow
intestinal exudates was studied when Mineral salt medium (MSM)
was supplemented differently with acetate (5% v/v), and methanol
(5% v/v) as carbon sources. Time-based growth patterns according
to media used indicated growth successions from MSM (pH 4) to
MSM/acetate to MSM/methanol when sampled at 1, 10, 20, and 30
days retention period. Total viable bacterial counts were
conducted using nutrient agar and showed highest growth of 9.6 x
1010 CFU/g for cow dung was obtained when sampled on
the 20th day, and the highest growth of 7.2 x 109
CFU/g for cow intestinal exudates was also obtained when sampled
on the 20th day. Bacterial counts for cow dung and
cow intestinal exudates sampled were higher on the 1st
day and reduced on the 30th day (4.5 x 107
to 3.4 x 104 – cow dung; 2.7 x 107 to 3.1
x 103 – cow intestinal exudates). Biogas yield for
cow dung had highest value of 51ml on the 17th day,
while gas yield for cow intestinal exudates was highest (48ml)
on the 16th day. Cumulative gas yields for cow dung
(901ml) was higher than cumulative yield for cow intestinal
exudates (871ml) after total retention period. Bacteria isolated
include Enterobacter species, Bacillus cereus,
Escherichia coli, Klebsiella pneumoniae, Staphylococus
specie, Citrobacter freundii, Proteus vulgaris, Salmonella
choleraesius, Salmonella typhi, Bacillus species,
Staphylococcus aureus, Yersinia pestis, and Clostridium
spp., and were all distributed throughout the digestion times
sampled (1st, 10th, 20th and 30th
days). Gas produced was flammable when tested with laboratory
fabricated bioreactors and burners.

Abstract:
The aim of this paper
is to emphasize the use of genetic engineering to improve the
oil quality in oilseed crops. Genetic engineering is a powerful
tool to enhance the nutritive values of oilseed crops. Naturally
the nutrition decreases due to constant growing of the different
crops on the same land. The need is to adopt modern techniques
that are less time consuming and give the best results.
Different genetic engineering techniques like hairpin mediated
transformation, gene silencing, Agrobacterium mediated
transformation, somatic hybridization are very helpful in
transforming the genetic makeup according to our own need. Plant
oils are considered beneficial when the level of Erucic acid and
Glucosinolates is low. This becomes possible through adopting
the modern techniques of genetic engineering. Major oilseed
crops like cotton, canola, soybean, sunflower need few genetic
modifications to enhance their oil quality. The main concern is
to introduce such genes which can add to its value. Through the
help of biotechnology, we are able to decrease the gossypol
level in cotton seeds and not in the leaves which is the
remarkable work of biotechnology. Tph1, tph2 and o1 genes are
introduced in sunflower to enhance Tocopherol level, which is
useful to maintain oil stability. Such as LPAT gene introduction
in soybean helps to enhance oil contents. Increase in soybean
biodiesel production is also achieved by genetic engineering.
Gene silencing also plays a major role to enhance stability of
oils by minimizing linolenic acid level.

Abstract:
The vital goal of this study is
examine the relationship between organizational commitment and
job burnout of personnel in health centers of Amol city.
Organizational commitment can be a simple belief in the values
and goals of the organization for which the three components are
considered. Home health care networks in the most peripheral
service-delivery units in the country. Health centers depending
on the geographic region, especially roads and population may
have one or more villages covered by its services. Health home
health workers serve only one job category, which according to
gender is called (male health workers) and (female health
workers). Many health workers in routine services cannot be
included employee service and often live streaming and daily
contact with the public health workers and rural families was
carried out.

Abstract:
In the Islamic criminal law passed in 1392; regarding a new
discipline; which was not mentioned in earlier articles; in the
seventh chapter of the new Islamic punishment low password in
1392; there are 2 articles under the new name '' semi free
system'' but under certain circumstances; they seem not dealt
with in an enough manner. therefore we must make use of the
experiences of other countries which these articles were put in
effect; so that it would give enough courage to the legislator
to put these two articles ''56 & 57'' in use; it looks as if the
legislator had feared the results to use them in a large scale;
therefore he made use of them in a very limited manner. But
experience showed their benefits were great; economically &
socially. We must prepare the society to acknowledge the
benefits of these articles; and protect them of being criminated
and not to be regarded as an enemy of the and miss users of the
customs& values of the society. If we were able to teach this''
semi freedom system'' to other criminals; better results would
be gained; here in this field; the role of the honored
professors & psychologists & the sociologists and those who care
about the society would be magnificent. And their point of view
would be of great importance and should be implemented by the
politicians. Because this system should not be looked upon
through political glasses; because crimes and criminals are a
totally social concept; not a political one. Anyway taking in
consideration that this is a new concept we may workout many
ways and subjects and find its faults & deficiencies and try to
eliminate them. Therefore in this thesis we may study its
benefits in 4 chapters to persons and the society.

Abstract:
This article is focused on the
control of permanent magnet synchronous motor function. Usually
with a variety of non-linear controller proportional-integral
controller is used to control the motors. However, the
controller is sensitive to changes in speed and load disturbance
and parameter changes. Conventional methods to overcome this
problem manually adjust the controller parameters. It results in
a Ziegler- Nichols method used to set the PI controller
coefficients, but this method cannot always be effective. In
order to overcome these problems, the fuzzy controller for
controlling PMSM motors is used. The performance of the control
authorities in tracking different
speeds using MATLAB
Simulink simulation is studied. In this study 49 inference rule
is intended to fuzzy logic controller system has been shown to
improve dynamic performance. The results of the simulations show
that the fuzzy controller in many cases have better performance
than conventional controllers.

Abstract:
The impacts of gas flaring on health at Ibeno, Eket, Onna,
Esit Eket and Umudike were investigated measuring air quality
parameters, The results showed that the mean concentration of
air parameters value were below FEPA and USEPA National air
quality standards with exception of carbon monoxide which
exceeded the limit of 35 ppm in March at Ibeno. Concentration of
air parameters at Umudike showed a similar trend to that of
study locations at Eket, Ibeno, Esit Eket and Onna. The values
also decreased drastically during wet season. Statistical analysis of the data showed some correlations between
CO, NH3 and pneumonia in Esit Eket and a reduced
correlation with respiratory tract infection (RTI). The result
also indicates that one is likely to be infected by pneumonia
when the volume of CO in air increases.
It shows that when the volume of
NO2 increases, the tendency for one to be RTI
infected is reduced. Another variable in this equation that
affect RTI is CO. The result also
shows if all other explanatory variables in this equation are
kept constant a 216% increase in CO will cause1% increases in
the chance of one to be infected with pneumonia in the research
areas.

Abstract:
The experiment was carried out at Agronomy Section of Kabba
College of Agriculture to investigate the effect of different
nitrogen sources on nodulation, nutrient composition, growth and
yield of soybean. The treatment consists of two nitrogen
fertilizer (urea and N P K 15:15:15) and three animal manures
(poultry manure, cow dung and pig manure). All these materials
were applied at 20kgN/ha at planting. The growth character
observed were plant height, number of leaves, stem girth, leaf
area, fresh weight of plant and dry weight of plant. Yield
characters observed were pod length, pod number, 1000seed
weight, and number of grains per plant, grain weight per plant
and yield per land area. Nodule characters observed were fresh
weight of nodule and number of nodule produced per plant. Data
were also collected on nutrient composition of soybean seed such
as N P K, S, protein, oil, and carbohydrate. All the data
collected were subjected to Analysis of Variance and treatments
mean were separated using Least Significant Difference. The
result shows that plots treated with N P K fertilizer at 20kgN
per ha gave highest yield of soybean. It is therefore
recommended to the farmers in the study area.

Radicalization Of Religion, Ethnicity And Sectarian Conflicts In

Abstract:
The scale and gravity of the abuses and the urgency of the
situation demand a swift and robust response – not only to
provide humanitarian assistance to those displaced and otherwise
affected by the conflict but also to ensure the protection of
vulnerable communities who risk being wiped off the map of Iraq.
A quick resolution is unlikely and impossible, but an increased
understanding of the regional scope of these problems is an
important step towards addressing them. In this case, as many
experts underline, the U.S. should not follow withdrawal from
Iraq with disengagement from the region – productive efforts
with regional allies are still possible and will be vital to
preventing the further deterioration of an already bad
situation. It should be very clear that increasing sectarian
polarization and violence is in the interests neither of the
regional players and their allies nor the whole international
community.

causes some problems for circuit breakers and other station
equipments. Using the series reactors is one of the methods for
reduction and control of the short circuit level. This paper
investigates the effects of the series reactor installation and
the requirements of the circuit breaker on the CB interruption
capability. The case study is a real power system in which the
FCL installation analysis is carried out. The IEEE C.37 Standard
is used for the selection of the size and the location of the
high voltage capacitors. EMTP-RV software has been used for the
analysis of the suggesting scenarios and frequency response of
the suggested topologies.

The principle of justice and
its role in interpretation of contracts

Abstract:
Fairness is a set of eternal and
timeless principles which can be the essence of human’s judgment
either in the case of nature or target. Some have understood the
fairness as the synonym of justice and some have made the
distinct and would say, justice like the law is a typical and
universal concept but fairness has a personal meaning namely a
diverse concept based on different people. And fairness in each
case has a specific statement while the justice is identical for
all people. Of course equality doesn’t imply the meaning of
equity, because the justice means setting anything in its own
position and in this sense it sometimes appropriates either
equality or inequality.

Investigating The Effect of
Number of Steps on Energy Dissipation of Stepped Spillways Based
on the New Design Approach

Dehloran branch, Dehaloran, Iran
mohammadkarami468@yahoo.com
Abstract:
Stepped spillways are hydraulic
structures that, because of their significant capacity in energy
dissipation, have been widely used by designers.
Flow mechanism over them
is complex and many investigations have been performed to study
that mechanism.
The effect of some parameters
such as the number of steps in energy dissipation has not been
fully investigated.
In this study the latest
design criteria have been reviewed and then an algorithm has
been developed to design the stepped spillways which are based
on the effect of number of steps. Results show that the number
of steps affects the energy dissipation.
With increasing the number
of steps energy dissipation increases and then decreases. Thus
for specific discharge and spillway slope, the number of steps
can be optimized for maximum energy dissipation.
By reducing design
discharge the optimum number of steps increases. Research work
on this subject can be continued in the future and various
aspects of the design parameters may be investigated
