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 rese
arch 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.
After the analyzing of formation pressure data and pressure
interference tests between wells in Ash Shaer field, the field has
been divided initially into three main blocks, then a material
balance model has been built for the field using MBAL software.
This model has proved the previous result besides answering some
problems which hasn’t been solved by the analytical method.
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 prop
erties 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).
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
cons
tants.
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.
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 wi
th some

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.
This research was conducted to study the feasibility of using

the (AL- Rasein Field).
At first ,a literature review of the Enhanced Oil Recovery (EOR)
methods in general was conducted ,especially Chemical Methods
,including Alkaline Flooding Methods.
We studying in this research the reaction with Zinc sulphate in an

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.
In this research we studied the relationship between the optical conductivity Ϭop and
photon energy (hν), the absorbance coefficient (α), transmittance (T), the refractive index
(no), and the real part and imaginary part of dielectric constant (εr,
εi), the spinning velocity
of deposition device (v), for a specific wave length (600nm), for a pure thin film prepared
from an organic polymer material, Polystyrene (PS), by spin coating technique, on three
velocities ( 1000-2000-3000)RPM, in room temperature and 1atm.
It was shown that the PS film is a transmittive film with a transmittance values
reach ( 85 – 90 )% in the infrared region, and the optical conductivity Ϭop increased with
the photon energy, and for the velocity 1000RPM it took the highest value ( 1.67 X
1014 )1/sec, at the photon energy (hν =3.1 ev) and the wave length ( λ= 400nm ),
which means that the optical conductivity Ϭop is active in the visible region, and also it
decreases with the spinning velocity.
The values of energy gap for allowed direct transitions were (2.5ev), (2.4ev), (2.3ev)
for the films prepared on 1000RPM, 2000RPM, 3000RPM, and for the forbidden direct
transitions were (2.3ev), (2.2ev), (2.1ev) respectively .
The biggest value of Urbach energy Eu was (163mev) on the velocity 1000RPM and
the lowest value was (109mev) on the velocity 3000RPM.
In this research we are Studying the improvement of the thermal

Adding such as (Boron & Titanium) .
In this Study we used (6063) aluminum alloy as a base metal
