استخدمت في هذا البحث الأقمشة التقنية كأغطية لسطح التربة تمنعها من الانجراف و تدعم نمو البذور كطريقة للتخفيف من مشكلة التصحر. حضرت خمسة أنواع مختلفة من الأقمشة من ألياف طبيعية: جوز الهند، و قنب، و جوت، قطن معالج و قطن خام. اختبرنا ثلاث خصائص هيدروليكية للأقمشة المحضرة: الانتفاخ، الامتصاصية للماء و النفوذية لبخار الماء. و وجد أن الأقمشة المحضرة جميعها هي مناسبة لمكافحة التصحر فجميعها تملك امتصاصية عالية للماء و تقلل من تبخر الماء، يملك القماش المحضر من الجوت و القطن المعالج أعلى امتصاصية للماء، و يملك القماش المحضر من القنب مع القطن الخام أقل نفوذية لبخار الماء.
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, treated 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.

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.
Hydraulic drives are able to generate high forces and move large loads. With the help of proportional
valves, it is possible to control movements fast and accurately.
Depending on the application, a linear cylinder, a rotary cylinder or a rotary mo
tor are used. Linear
cylinders are most frequently used. The following designs are therefore confined to this type of drive. We
compare among various types of cylinders which are common by used. We compared different conditions
for cylinders with friction and without it.
A Study was carried out to evaluate the impact of some insecticide.
The results showed that no effects on growth of the studied fungi
were observation when Deltamethrin and Chlorpyrifos were used by
the low concentration.
The extensive theoretical and empirical studies about the
pressure and flux speed of an incompressible fluid have shown a
number of varied hydraulic problems. This is as a result of
insufficiency In analyzing and studying the variable forces and
factors that are changing in both direction and magnitude. These
forces appear when a fluid flows inside permeable cylindrical
pipes. For this reason , we took into consideration all factors and
losses affecting this case. Based on that, we obtained new
mathematical equations to calculate both pressure and speed.
Then we placed a solved arithmetic example. Through which we
showed the tendency to reach constant streaming at all times
studied after adding the new parameters.
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 va
riables 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 .
