يهدف البحث إلى دراسة تأثير امتصاصية أنابيب البولي إيثلين عالي الكثافة HDPE لبعض المركبات الهيدروكربونية على القيم المميزة لمنحنيات (القوة – الاستطالة). لتحقيق هذا الهدف تم غمر عينات مقتطعة من أنبوب واحد في أوساط هيدروكربونية مختلفة تحتوي الغازولين و المازوت و زيوت محركات عيار 10 و عيار 40. أظهرت النتائج وجود تأثير فتاك لهذه المواد على كل من قوة الخضوع و تشكل العنق و قوة التحطم، كما أظهرت النتائج التجريبية أن زيوت المحركات تبدي تأثيراً مماثلا" لتأثير البنزين على الرغم من النسب المنخفضة للامتصاصية.
The aim of this research is to study the absorptive effect of high density (HDPE) polyethylene pipes for the hydrocarbon compounds on the characteristic (Force, Elongation) curves. To verify this, we immerse some parts of the pipe in different hydrocarbon mediums containing gasoline, diesel, and motor oils of (10 and 40) calibre. The result show that these compounds have a bad effect on the submission force, neck formation, and damage force. The experimental results also show that motor (engine) oils have a similar effect on gasoline despite low absorption percentages.

The objective of the study was to determine experimentally
the dust pollution of polyethylene pipe during head- to - head
welding in the workshops piping and its impact on the efficiency of
welding.
هدفَ البحث إلى كشف احتمال حدوث هجرة متعاكسة بين المواد المضافة إلى البولي إيثيلـين عـالي
الكثافة المستخدم في صناعة عبوات تعبئة زيت الزيتون البكر و الزيت المعبـأ، و قـد صـممت التجربـة
بالاعتماد على حبيبات البولي إيثيلين من جهة للحصول على أعلى سطح تم
اس ممكن بزيـت الزيتـون،
و باستخدام نوعين منها أحدها أبيض اللون و الثاني أحمر، كما درس تأثير كل من زمـن التمـاس بـين
الحبيبات و الزيت و زمن تخزين الزيت من جهة أخرى. و لتحديد ما يجري فعلاً عند تخـزين الزيـت فـي
العبوات البلاستيكية بأبسط الطرائق، درس كل من رقم الحموضة، و رقم البيروكسيد، و لزوجـة الزيـت،
و كشف وجود مركبات الدايينات المهاجرة على موجة امتصاص UV)232nm) ، فضلاً عن دراسة العـد

Water sources in Syrian coastal area have a great importance due to the variety of the
sources and the urgent needs to water for drinking and irrigation. Therefore great efforts
are made to protect water sources from contaminants. This research aim
ed to study some
contaminant indicators in some drinking water sources in the Syrian coastal area. The
study included determining the concentrations of nitrates, nitrites and some heavy metals
including lead, cadmium and zinc in water samples taken from five sources of water
distributed from north Lattakia to north Tartous. The results showed that the concentrations
of nitrate, nitrite and heavy metals differ depending on the water source. However, all
these concentrations were lower and within the acceptable limits of Syrian standard for
drinking water. The study concluded that water resources in the coastal area are
distinguished with their relative purity and contaminants little reach.
The aim of this work is to study the rheological and mechanical properties of Poly(lactic acid) and High density polyethylene and blends (PLA/HDPE) in the molten state with recpect to shear stress, temperature and blends compositions using brabender mixer.
The effect of adding two organic acids(formic acid, acetic acid). with broiler drink
water was tested to evaluate their efficacy on the their performance and health Groups
treatment consumed amounts of feed that are greater than the control but for
The results in
the six trials showed superiority of the feed conversion ratio and the final weight of broiler
in the two groups that was added complex to its drink water, compared to the control with
significant differences at 0.05.
There was no significant difference between the replicates of each trial on its own
while the results of laboratory parasite testing of samples litter showed that the number of
oocysts in the litter was the lowest in the treatment groups with significant differences
compared to the control. It was noted that the number of oocysts in litter increased until a
certain age and then began to decline.
The results also showed reduced mortality in all trials with treatment and there were
no significant differences in treatment groups compared to the control.
