يهدف هذا البحث إلى دراسة بعض الخواص الترموديناميكية لبعض السوائل العضوية اعتمادا على قانون الحالات المتقابلة و ذلك باستخدام المتحولات عديمة القياس ( البارامترات المحولة ) في معادلة الحالة للسوائل و الغازات , حيث تعتبر هذه المتحولات هامة جدا في التطبيقات العملية نظرا لكون قيم هذه المتحولات عند النقطة الحرجة متساوية و تساوي الواحد من أجل جميع المواد . و في بحثنا هذا سوف نستخدم الطريقة الخوارزمية لحساب هذه الصفات لبعض السوائل العضوية معتمدين على قيم هذه البارمترات المحسوبة بطرق تجريبية من قبل بعض الباحثين , و استخدامها كمعطيات أولية للوصول إلى استنتاج هذه الخواص و الصفات وفق الطريقة الخوارزمية ثم مقارنة ما توصلنا إليه مع القيم الموافقة في أعمال أخرى .
This Research aims to study some thermodynamics properties for some organic liquids depending on the law of corresponding states using the dimensionless variables ( transferred Parameters ) in the law of condition for liquids and gases . These variables are considered to be very important in practical application because its values at the critical point are equal to one in all materials . In our research we will use the algorithm method to calculate these properties for some organic liquids depending on the values of these parameters which have been calculated by experimental methods by some researchers . And then we will use them as primary data to conclusion these properties according to the algorithm method and then compare the result we get with the result in other researches .

This Research aims to study the heat capacity for some
organic liquids depending on the law of corresponding states ,
using some analytic equations which are related with the
reduced temperatures and the parameter of similarity in
ranges of tempe
ratures below the critical temperature .
Then to conclude the heat capacity with a constant pressure
and compare the results with values of the heat capacity in
other works which have been obtained using different
methods , theoretical or experimental.
This study was conducted during the 2011-2012 and 2012-2013 seasons in
Abu-Jarash orchards area in Damascus to identify the effect of improved
organic materials as sludge, manure and compost in improving some soil
physical characteristics and whea
t productivity. Results showed that the three
types of organic material affected the physical characteristics of the studied
soil. They decreased its bulk density, increased its total porosity and increased
its ability of holding water at field capacity. Results also showed that the
compost of city wastes was the best in improving soil physical properties. The
three organic materials, particularly the sludge increased the total productivity
of wheat (Sham3).
The ideal selection of raw materials in manufacturing process is a very important step to
develop this process and to improve the product. For this purpose, we search for initial
parameters to guide us in using clay materials (wherever it locate) i
n ceramic industry. These
parameters depend on physical properties of clay (Atterberg Limits). We follow experimental
and analytical methods for laboratories tests applied or clay, and for ceramic samples tests. We
deduct initial parameters which determine technical specification values for ceramic product,
and we derived mathematical formulas between clay properties and technical specification for
ceramic product. These parameters and formulas help us to achieve ideal investment for clay
ambushes either as pure raw materials or with suitable additives to reach on acceptable value
for water absorption of ceramic product which, at the end, specify the type of product according
to international specification.
In this research, technical fabrics are used as blankets which prevent soil surface erosion and promote
seed germination as way to mitigation of desertification .
Five different types of fabrics are prepared of natural fiber: coir, hemp, jute, trea
ted cotton and raw
cotton, then three hydraulic properties for prepared fabrics are tested: swell, water absorption, water
vapour permeability.
It is found that all types of prepared fabrics are suitable to combat desertification whereas they have a
high water absorption and they reduce water evaporation, the fabrics of jute and treated cotton have the
highest water absorption and the fabrics of hemp and raw cotton have the lowest water vapour
permeability.
Terebinth trees have been occupying a good part of the mount of Syrian
(abed elaziz, pelass). The Pistacia atlantica fruit, rich in oil, is used by local
inhabitants in many ways, few studies investigation of the P. atlantica fruit oil
of Syria ha
s been carried out,This study investigates the protein, ash, crude oil
and oil composition of P. atlantica with respect to total phenol, iodine value and
saponification value, in order to classify it among the other known edible oils
thenafter compare the oil composition with the oils of other Pistacia species.
The fruit of P.atlantica appears to be rich in oil. The major fatty acid in the
sample studied are oleic, linoleic, our results show that. The oil has a higher
content of unsaturated FA (oleic + linoleic = 72%). The oil can be classified as
an oleo-linoleic vegetable oil. The biochemical data showed an elevated MUFA
content (50-48%) which may constitute an important property against certain
pathologies for its nutritional and preventive virtues.
