تم تنفيذ البحث في مركز الكريم لبحوث تربية و تحسين الأغنام و الإبل بالسلمية, حيث تمت الدراسة على 9 روؤس من إناث الإبل ضمن حظائر نصف مفتوحة و نظام رعاية شبه مكثفة, و غذيت الإبل على علائق من دريس الشعير و البيقية و بعض الأعلاف المركزة. و حددت الخلطات العلفية بما يتناسب مع الحالة الفيزيولوجية و العمرية لحيوانات الدراسة, كذلك طبق على القطيع نظام التلقيح الوقائي وفق برنامج الحصينات الوقائية.
The research was carried out in the center of the Research and Improvement of Sheep and Camels in salamiah. The study was conducted on 9 female camels, within semi-open barns, semiintensive care system, and the camels were fed on mixtures of barley, vetch and some concentrated fodder, Fodder mixtures were determined to suit the nutritional needs of the physiological and age-related condition of the study. The herd was also applied to the preventive vaccination system according to the preventive immunity program.

This research was conducted in Agriculture College (Food Science Dep.,
Damascus U university). The purpose of this research was to evaluate Cherkes
Cheese by determination some Chemical and microbial properties for 40
samples collected randomly fr
om different places Damascus and country sides.
The results showed very deferent changes in Chemical properties. The acidity
ranged between (0.25 - 0.54%), moisture content (38 - 56%), and total dry
matter (44 - 62.7%). Results also showed that all samples were rejected by
(Syrian Normal Standard)for fat content in dry matter (20 -33%). Fifty percent
of samples were rejected for their content of sodium chloride which was
(1.2 - 4.3%). Results also showed that samples were free of Salmonella and
there was no rejection for existence of Staph. aureus but 37.5 % and 10% of
samples were rejected by (Syrian Normal Standard)as per content of coliform
and E.coli, respectively.
The study was accomplished on proteins (caseins – whey proteins) of local milk after producing casein by precipitation with ethanol , and whey proteins by heat precipitation. The functional properties (Water Binding – Emulsifying Properties – Gelatio
n) were studied on prepared milk proteins , the witness experiment (pure casein) was followed for comparison.
This functional properties were repeated after adding xanthane and starch with three different concentrations for each kind of proteins , then the results were compared. For statistical analysis, the system of totally –random selections was applied, and a comparison was made as of L.S.D test, and possibility level at 5%. The results showed improvement in functional properties of prepared milk proteins when xanthane and starch were added in the percentage ( 5 - 5 – 10 % ) for the properties (Water Binding – Emulsifying Properties – Gelation ) respectively.
The main aim of this study was to determine the effect of slope position on some
soil physico-chemical properties .The study was conducted on a pine forest soil , Tartous.
Soil samples were collected from top , mid and bottom slope positions at hor
izon- A and C
of top and mid slope positions and at horizon A,(B)and C of bottom slope positions .
Results showed a significant difference among the physico-chemical properties of top ,
mid and bottom slope soils . Bulk density of the top - slope (1.34 gcm-3) was the highest
followed by mid ( 1.31 gcm-3) and bottom slopes (1.27 g cm-3) .Conversely ,Organic
matter content (2.86%) ,electrical conductivity EC(0.20mmos/cm) , calcium(28.3
meq/100g) , magnesium(6.80 meq/100g) , Potassium (0.21 meq/100g), Soil pH ( 7.95) ,
clay content (38.43 %) and silt content (34.70%) were the highest at bottom slope followed
by mid and top- slopes , respectively . Soil A and C horizon of top and mid slope positions
and A ,(B)and C horizons of bottom slope positions were also significantly different in
their physical and chemical properties . Horizon A had the highest organic matter
,electrical conductivity , calcium , magnesium , silt contents and lower bulk
density,CaCO3, sand contents than both the (B) and C horizons of bottom slope and the C
horizon of top and mid slope .The deterioration in physico-chemical properties of top slope
as compared to mid and bottom slopes and that of A horizon as compared to C horizons
were presumed to be due to past soil erosion effect that removed the finer soil particles
including soil organic matter and other plant nutrient.
Cornstarch has been added, with percentages of ( 5%, 10%, 15%,20% and 25%), to
flour beans both types paste (peeled and non-peeled) prepared for the manufacture of a
quick vermicelli preparation (noodles), in order to study the effect of the additi
on of some
chemical and organoleptic characteristics of this product and to determine the ideal
proportion of corn starch added.
The study has shown that there is an inverse relationship between the reduction of
protein content and the increase of the fat percentage and the increase of starch proportion
up to (25%) in both kinds of bean noodles: peeled and unpeeled.
Increasing the ratio of starch above 15% has affected negatively the resulted noodles
colour and some organoleptic characteristics such as taste and smell with the emergence of
a gradual improvement of the appearance of noodles that resulted from flour peeled beans.
Finally , it was found that the best ratio of added starch is 15%.
In this work composite hybrid materials were prepared from a base
material composed of epoxy and phenol - form aldehyde resins and
reinforced by 30% wt alumina and silica powders and asbestos
fibers. For samples were prepared with. Different ratio of
reinforcing material.
