The research was conducted in village Habbet in Hafa (Lattakia region) 300 meters above
sea level during the period of 2016-2017 the plant material of the research is red cabbage
Ruby King F1 hybrid in order to study the effect of planting date on
growth and
productivity of red cabbage. The study consisted of five different planting dates during the
med of May, June, July, August and ,September months The completely randomized block
design was used with four replications and twenty plants in replication . The study contains
indicators: )leaf surface area, shape, volume, solidity and weight of cabbage heads, inner
stem length, total and marketable yield, percentage of marketable yield and content of
vitamin C)
The results showed that planting treatment during August and September gave the superior
results with significant difference in vegetative and productive indicators: leaf surface area,
solidity and weight of cabbage heads, total yield )3394.8، 3654( kg/d respectively,
marketable yield and percentage of marketable yield.
While The planting during May, June, July was superior on content of vitamin C which
was respectively (99.58, 98.68, 97.82 ( ml/100g with significant difference.
The experiment was conducted during the two seasons (2015 , 2016 ) on the Lemon trees
cv (Meyer ) aiming at studying the effect of the foliar spraying with the nutrients ( boron ,
zinc and iron ) on physical and chemical properties of the fruits Th
ese nutrients were
sprayed separately or as a mixture .
The average of each of the physical properties of the fruit (length , width , firmness,
volume and weight of the fruit ) , in addition to rind thickness and the fruits ` juice volume,
,the chemical properties of the fruit juice (total soluble solids, total sugars, total acidity,
vitamin C) were studied. An increase was observed in all the studied parameters in the
sprayed treatments compared to the control from( 6.37%- 3.33% -0.37% -
34.57mg%)to(9.33% -4.88% -1.89% -43.5%) in the first season and( 9.75% 5.87- 3.32% -
45%) in the second season, respectively. As a result of the statistical analysis, there were
significant differences between all the studied treatments and the control with overpass of
the treatment of the three elements (iron chelate + boron oxide + zinc chelate ) of all
treatments in the most of the studied figures in both seasons. Statistical analysis of the fruit
rind thickness showed the absence of the significant differences among the studied
treatments.
There are a lot of studies with conflicting results about the correlation between blood
levels of vitamin D and lipid profile (total cholesterol, LDLc, HDLc) and the effect of
treatment with vitamin D supplements on it. This study aimed to investig
ate the effect of
vitamin D and calcium supplements on lipid profile.
This study included 59 volunteers who received these supplements for prevention of
osteoporosis as a prescription from orthopedic doctors between 11/2016 to 1/2018. The
average of age was 49±8 years. The plasma values of TC, LDLc, HDLc were measured
using enzymatic colorimetric method ( Biosystems kits ) in Tishreen hospital before
treatment and after two months. The results were analyzed by T-Student test, and P value
<0.05 was considered significant. The mean plasma levels of LDLc before treatment were
(100.983 ±28.36) mg/dl, and after two months of treatment were (102.249±27.478) mg/dl,
and the difference was not significant. The mean plasma levels of HDLc before treatment
were (68.056 ±14.369) mg/dl and after two months of treatment were (62.715 ± 14.39)
mg/dl, and the difference was significant. We advise to measure plasma lipid levels during
treatment with these supplements depending on the changes that observed in this study.
The search has been performed on blood samples from cows with
different ages and various multi-productive purposes from a
number of farms to detect sera-prevalence percentage of brucella
abortus infection in cows using Competitive Enzyme Linked
I
mmune Sorbent Assay. The test results have shown general
serum spread by the percentage 5882%. The rate of antibodies of
serum spread in the cows in different farms under study have
been between 0.00% and 16.66%.
In research we studied the effect of vitamin C on the level of total
cholesterol ،triglycerides ، (HDL) and (LDL) in the stressful
rabbits blood by hydrogen peroxide (H2O2) . We used 30 rabbits
were divided into three groups:First groupnot stresse
d (control
group) ، Second group (Group stressed by H2O2) left without
treatment until the end of the experimental period ، third group
(Group stressful by hydrogen peroxide) was given orally vitamin C
solution at a rate of 100 mg / kg of body weight per a day for five
weeks.
Thin walled Steel products are very much used in the construction industry, where it
is cold formed from uniform thickness steel plates. This study aims at determining the
optimal section of cold formed thin walled lipped C compressed member under
the effect
of several levels of axial force using Genetic Algorithm.
The research found that the genetic algorithm is able to resolve the issue of the
optimal design of studied column with high efficiency, accuracy. Also it found that the
torsional flexural buckling constraint and the overall buckling constraint in x-direction are
the effective constraints in case of long height.
The study recommends restudying the same issue as a multi objective optimization
problem by adding additional objective functions which are the overall buckling in x&y
directions.
The bio-effect of anise oil and its fruit extracts(alcoholic and
aqueous extract) to control the cowpea beetle, Callosobruchus
maculatus that infest stored leguminous crops was investigated. The
study was conducted according to three treatments: e
vaporation,
direct spray of insects and food spray. The anise oil was used at
different concentrations from 0.05 to 5%. Whereas, the aqueous and
.alcoholic fruit extracts were used as 30%.
As known the electric energy is one of the most important factor of development, but
using it causes bad environmental impacts due to depending on fuel as the source of
electrical generation. Using renewable energy is still limited and needs a huge
fixed costs,
so it is important to reduce electrical consumption by monitoring and controlling
equipment to achieve its function with lower consumption. HVAC sector is the most
consumption part in buildings, therefor any saving in this sector will affect manifestly on
the total electrical consumption in the building and this is done by control system. Control
systems are in continuous improving, so it is needed to exploit them in saving electrical
energy.
In this research, studying control of VAV system and designing fuzzy logic
controller to drive supply fan in order to reduce its electrical consumption, this is
performed through designing practical prototype of the supply fan with its tools and
software which are designed to view the electrical energy saving which we gain it by using
fuzzy logic controller.
Cold formed steel (CFS) has many advantages over other construction materials.
CFS members are lightweight. They weigh up to 30-35% less than their wood
counterparts.. This makes CFS members economical and the same time very easy to erect
and inst
all. They may be shaped (cold-bent) to nearly any open cross section. This allows
for the use of optimization technique’s to find optimal shapes for the members’ cross
sections.
The research aims to show the genetic algorithm's ability in determining the optimum
dimensions cold formed C section. To do so, the optimum design mathematical
formulation was formulated by adding the manufacturing constraints that reflect the
section folding operations in addition the geometrical and structural constraints.
The research found that the genetic algorithm is effective tool in finding the best
solution to this issue, as it showed its ability to deal with asymmetric section through
reaching solutions conform to the basic principles of mechanics of material.
The algorithm is adjustable, so that it can implement the design restrictions which are
compatible with any codes or any manufacturing requirements imposed by modulation
techniques.
This study aimed to evaluate the clinical and microbiological effect
