Evaluation The Hydrogeological Conditions of The Unconfined Aquifer in The Area Located Between The AL-Sin and AL-Rous Rivers in the Syrian Coast

The research area is located in the Syrian coast between the Sin and Rous river. This research aims at studying the hydrogeological characteristics of the unconfined aquifer in the research area and evaluating the conditions of its placed. The research was based on a monitoring network consisting of 36 wells that penetrate the unconfined aquifer, and measurements continued during the period (October 2016 until September 2017). The unconfined groundwater depths in the research area range between 0.5-11.5 m, and sometimes during the drought period reach to 13.5 m, while it is close to the surface in the winter and up to 0.1m in some wells. The electrical conductivity ranges between 550-3700 μs/cm, increasing as we go west and reaching 9,000 μs/cm and more in the wells near the sea during the dry period. Groundwater levels Lower in the dry period to below sea level in near-shore wells, achieves the hydrodynamic conditions of the seawater intrusion.

The study of manufacture conductive yarn

The majority of known polymer materials are electrically insulating. But there are some of polymers are intrinsically conducting in nature, However, it is lacking in process ability, and the scope for manipulation of electrical and mechanical properties is limited. The method which used to solve this problem is an addition of a conductive metal filament into a polymer filament yarn. Which can be directly integrated into a textile, or can be knitted. So we made a device able to produce this kind of conductive yarns which depends on melt spinning technique but with the elimination of necessary pressure for extrusion. And we were able to produce samples of copper filament coated with polymeric material (low density polyethylene).

Electrolytic plating of Cadmium with Maleic Acid

We studying in this research the reaction with Cadmium sulphate in an aqueous solution by physical - chemical method in presence of MaleicAcid , and determined compounds which are formed in this solution and we calculated of it formation the constants. After we used these electrolytes in plating by Cadmium , that is by electro precipitation of this metal on the solid electrodes (steel, copper) so that we definite the best of these electrolytes for galvany and the set necessary conditions for its use.

Calculating the conductivity and dielectric constant in quantum Fermi Plasma under external magnetic field

Landau,s – Silin Semi Kinetic Equation has been solved by this scientific paper. After taking into consideration the mutual effect between quasi particles in Fermi's Plasma under a magnetic field to get more accurate results related to coming up with some characteristics of this sphere. Like the conductivity and dielectric coefficient due to their necessity in the plasma's characteristic study depending on Landau's parameters and comparing them to the results of other ways for these parameters to be calculated.

Corrosion Study of Iron and how protection it

We studying in this research the reaction with Zinc sulphate in an aqueous solution by physical - chemical method in presence of Succinic Acid , and determined compounds which are formed in this solution and we calculated of it formation the constants. After we used these electrolytes in plating by Zinc , that is by electro precipitation of this metal on the solid electrodes (steel, copper) so that we definite the best of these electrolytes for galvany and the set necessary conditions for its use.

Study the ellectriicall propertiies off Co Zn - ferriites doped by Nii at diifferent frequenciies

This work includes study of Co Zn-ferrite samples doped by Ni which prepared by Ceramic method. Then verified that it had spinel structure by using XRD. In addition we study properties such as electrical resistivity , electrical conductivity , dielectric constant and loss coefficient. And also we have studied variations of this properties in terms of temperature at different frequencies in the range of (20 -105) Hz.

In this research we studied the mechanism of the reaction the solution ( Malonic acid , Zinc , Water ) by using different methods.

بعض العوامل المؤثرة في مستوى الناقلية الكهربائية في حليب الأغنام و علاقتها بمؤشرات الحليب الأخرى

أجريت الدراسة في مركز بحوث تابع لمعهد تربية الحيوان و رعايته مع مستوصف الحيوانات بكلية الزراعة جامعة مارتين لوثر ألمانيا. استخدم لهذا الغرض 58 نعجة منتجة للحليب من عرق الايست فريزيان لمعرفة تأثير كل من وقت الحلابة، و نصف الضرع، و يوم الاختبار و الخواص الفردية للحيوان في مستوى الناقلية الكهربائية في الحليب و علاقة ذلك في مؤشرات الحليب الأخرى. تم قياس الناقلية الكهربائية من السحبات الأولى قبل الحلابة الصباحية و المسائية مباشرة و ذلك من كل نصف ضرع على حدة بواسطة جهاز يدوي، و بعد القياس أخذت عينات حليب بمعدل 30 مل من كل نصف ضرع على حدة أيضًا لتقدير عدد الخلايا الجسمية و مركبات الحليب الأساسية. و بعد الحلابة أخذت عينات حليب تمثل كامل كمية الحليب المنتجة و من كل نعجة لتقدير مؤشرات الحليب السابقة نفسها. و خلال فترة الدراسة أخذت أيضًا عينات حليب للفحوصات البكتيرية.

Study of Palaeomagnetism and Some Magnetic and Physical Properties of Some Tertiary Igneous Rocks between Sana’a and Al-Hudyadah Region (Republic of Yemen)

Palaeomagnetism and some magnetic and physical properties (magnetic susceptibility, intensity of the Natural Remnant Magnetization (NRM), ac current electrical conductivity and density) of 136 samples from 22 sites of the Yemen Volcanic Group TKY (Tertiary and (or) Cretaceous) from igneous rock exposures along the road from Sana’a – west towards Al-Hudyadah were studied. A single population consists of seven Virtual Geomagnetic Poles (VGP), of the Upper Oligocene, was accepted and a mean at 182.81° E, 77.44° N with α95= 12.5° was calculated. The different properties were measured in order to use these properties as characteristic factors to discriminate the neighboring igneous flows. The measurement of the in situ magnetic susceptibility of 140 points, distributed on 7 sub-areas, in the region helped to calculate the mean value of the magnetic susceptibility of each sub-area, which might be used in any magnetic interpretation of aeromagnetic or magnetic anomalies. Also, the density of 132 samples were measured and a mean value of the density of each sub-area was calculated in order to be used in any future interpretation of any gravity anomaly in the area.
