هدف البحث إلى تقييم فاعلية إضافة تراكيز مختلفة من الغلوتامين (25و 50 ميلي مول / مل ) والبرولين (25 و 50 ميلي / مول ) وفيتامين B12 ( 2.5 و 5 ملغ / مل ) إلى محلول تمديد ( سترات صوديوم وغلوكوز مع صفار البيض المحضر مخبرياً , ومقارنتها مع محلول تمديد تجاري جاهز Andromed كمحلول قياسي في حفظ السائل المنوي في ذكور الماعز الشامي .
The aim of the research was to evaluate the effectiveness of adding different concentrations of glutamine (25 and 50 mmol / ml), proline (25 and 50 mmol / mol) and vitamin B12 (2.5 and 5 mg / ml) to an extension solution (sodium citrate and glucose with egg yolk prepared in the laboratory, And comparing it with a ready-made commercial extension solution Andromed as a standard solution in preserving semen in male Shami goats.

The research aims to determine a water Quality Index for the Lake of 16 Tishreen
Dam. To achieve this aim we have carried out a different periodical physicchemical and bacterial measurements on the water of the lake. The Samples were
taken at five
sites along the lake for a period of complete year. The indicators that
، NO2، NO3، BOD5، DO، EC، PH، Turbidity،have been measured are: Temperature
and ، F.C. Measurement results were represented diagrammatically،PO4،NH4
compared with the Syrian Specification Standards for portable Water. The lake was
Canadian Indices ، classed according to these Indices: Malays quality index
(NEWWQI). The Lake was Classed according to these indices as ،(NSFWQI)
from second grade at ،following:from third grade at all locations (Malays Index)
and from ،the middle lake and from a third grade to all other locations (NSFWQI)
second grade at all locations (NEWWQI). According to this indices the water is
not good for drinking and needs treatment. The Productivity of the lake was
determined. The Lake is Eutrophic according to TN-TP in the middle but
Hypertrophic accordingtoTN-TP in all other location
This experiment was conducted at Kharabo farm, Faculty of Agriculture,
University of Damascus. A total of 252 chicks of Japanese quail breeder females
were distributed on the first day of life into two groups, Gicks in G1 were
reared from 1-28 day
s of age under ideal required temperature according to
their age, while chicks in G2, were subjected to heat stress from 8 am to 5 pm at
42 °C from the first day of hatching until 28 day of age and to the ideal
required temperature from 5 pm until 8 am. Chicks of each group were
distributed into three subgroups, with three replicates per subgroup.

A hydroponic culture experiment was conducted under the green house
conditions, at the general commission of scientific agricultural research, and
the faculty of agriculture, Damascus university, during the year 2002-003.
The objectives of this in
vestigation concentrated on the influence of four
salinity levels (0-50-100-150 mM NaCl) on some physiological parameters of
eight sorghum genotypes. The experiment was designed in a RCB design with
three replications.
This research aims at studying the effect of irrigation with different levels of NaCl on
the growth and development of Syrian pears (Pyrus syriaca). The results showed that:
1. Salt stress reduced chlorophyll content (a,b and a+b) in salt treatment
s compared to
the control , which contained 67.48 mg/g (a), 111.62 mg/g (b) and 204.76 mg/g (a+b),
while 1750 ppm of NaCl treatment contained 49.34 mg/g (a), 49.86 mg/g (b) and 158.77
mg/g (a+b) respectively. Treatment with 500 ppm of NaCl increased significantly
chlorophyll content compared to other salt treatments.
2. Leaves content of proline increased with increasing NaCl levels. It reached 870.8
ng/g when irrigation water contained 1250 ppm of NaCl, while it decreased in other salt
treatments. Leaves dry matter increased with the increase salt levels (24.50% for the
control, and 44.86% for 1750 ppm of NaCl).
