تناول هذا البحث خطوات رئيسية تتعلق بتحضير الغذاء الحي اللازم لتربية يرقات مختلف أنواع الجمبري البحري, اذ تم في هذه الدراسة عزل نوعين من العوالق النباتية وحيدة الخلية هما Tetraselmis sp ,Chlorella sp و ذلك من عينات ماء جمعت من شاطئ جبلة و تنميتهما في أوساط صلبة و سائلة مخبرياً في كلية العلوم – جامعة تشرين و ذلك خلال الفترة الواقعة بين شهري نيسان و أب 2013.
This research deals with amain steps related to preparing live food which is necessary to grow up larvae of different species of marine family Penaeidae prawn, in this study the isolation of two species of phytoplankton one cells they are Chlorella sp, Tetraselmis sp, and the specimens are collected from littoral of jableh and rearing them up in hard and liquid medium in laboratory in Faculty of Sciences, Tishreen University, in the period between April and august 2013.

Resin based composite considers substantially as a restorative
material in clinic. Dentists concern in placement resin composite
restorations with Long term survival.
Materials and Methods: 20 Non carious human third molars, class I
cavity was pr
epared in every molar, restored with methacrylate
resin composite Tetric EvoCeram. The restored teeth were
subjected to thermocycles. Specimen was randomly divided into
two groups : the first group 10 restorations, were repaired by
Cojet® (3M ESPE, Germany) and restored by Filtek™ P90, the
second group 10 restorations also repaired by Cojet ® but restored
by Filtek™ Z350 XT. After that all teeth were subjected to
thermocycles again, later immersed in 0.5% basic fuchsin solution
for 1 s. The teeth were transversely sectioned and observed under
a stereomicroscope. The degree of dye penetration was recorded
and analyzed.
Results: No statistically significant differences in microleakage
were observed between two groups either with low shrinkage
Silorane resin composite or methacrylate resin composite
This research concludes an determination of some Culicinae mosquitoes
distributed in south of Syria.
The study show that there are 14 species, 3 of them were recorded for the
first time in the study area, these 3 species were described, illustrate
d , and
distinguished from related species ,the seasonal reproduction and the habitat
types of these were studied .
(Culex perexiguus , Cx.sinaiticus , Cx.territans).
The research aims to identify the reality of food in Syria during the 2011-2012 period
and compared to the situation before the crisis (2008-2010). The study showed that the
total cultivated area in Syria during the crisis amounted to about 4479 th
ousand hectares,
and the total lack of 323 thousand hectares from the pre-crisis period, as well as the
decreasing size of the vegetation of agricultural production during the same period
increased by 3081.2 thousand tons to score 11021.5 thousand tons, However, the
availability of vegetarian food and animal size increased overall during the period of crisis
by 923.7 thousand tons to score 18704.1 thousand tons, With regard to per capita food
shortage has been during the crisis period by 8 kg to score 864.8 kg while it was before the
crisis 872.8 kg, With regard to the value of the food gap turned out to be increased during
the crisis by 640.5 million dollars to up to 1727.2 million dollars,. And finally the study
showed that the demand for food will increase in Syria during the period 2016-2020, as
will 22832.5 thousand tons in 2020, so the size of the domestic production of Syria, to be
achieved in 2020 will be 18170.8 thousand tons.
The aim of study was to determine the dates of breeding and sexual maturity for
Marsupenaeus japonicus in Lattakia coast as introduce for hatching and culturing it.
The specimens were collected from the sea water of Ibn-Hany area at the north of
L
attakia, during the period November 2010 to October 2011 once or twice monthly. In
vitro study included distinguishes males and females, morphometric measurements and
weights for all individuals. The genital maturity stage was determined externally and
through histological sections.
This research is concerned with clarifying the conception of the “Descent
Noble Breeding of the FAMILY in the “ Divine Law” - sharia’ - . It also clarifies
the aspects that Emphasizes the supreme consideration and carefulness of the
Islamic Sharia
’ that a healthy Moslem family and its members enjoy within the
‘Divine Law’ physically psychologically and morally..
