In this research electrochemical treatment was used to treat Al-Sin water that feed Banias
thermal station boilers for generate electricity , this recycled pure water minimize
corrosion and wear of turbine, the current of (2A) and (12V) was applied
by
Transformer on metal electrodes of aluminum. The electrochemical treatment efficiency
was studied.
Results revealed that the turbidity decreased for about (98%), and that total dissolved
solids (TDS) and conductivity were reduced by about (61%) and (70.8%) respectively after
one hour of treatment process.
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.
The idea of this research is about the study of the change of thermal
conductivity of blend mixture composed of Syrian woolen fibers with concrete
of equal weight percentages of 0,5%, 1%, 2% and 4% respectively. the purpose
is to diminish the ratio of the thermal loss in the building.
This study investigated the effect of adding different
percentages of sand to several types of clay soils, Which used as
liners at solid waste landfill sites in order to find the best mixing
ratio (sand - clay).
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
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.
This research was conducted to study the feasibility of using
Alkaline Flooding (AP) to increase the displacement factor from
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
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 const

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

The Phase Change Materials (PCM) are materials which absorb a great quantity of
energy during the change of phase solid /liquid and relies it during solidification
An application of these materials is thermal energy storage. The PCM integrated into
materials of the building can reinforce their inertia and reduce the power necessary for the
heating and air conditioning. This is particularly true for the buildings of the tertiary sector
whose envelope is light. Nevertheless, one of the characteristics which limits the use of the
PCM is their low conductivity.
The objective of this article is to propose a selection of materials having a
conductivity high enough to make it possible to ensure an air conditioning in summer
while limiting, even while removing, the use of energy (electricity or fuel) thanks to walls
containing these PCMs. This article consists of two parts:
- The first part exposes the problems of the study and specifies the context in which
the use of a PCM as a passive air conditioning system fits.
- The second part fixes the selection criteria which will allow, in a first approach to
choose certain materials.
