This study deals with the determination of the quantity of solid dust particles deposed
on the leafs of some trees along Syrian coast and the concentration of some heavy metals
in it (Zn, Fe, Pb, Cu, Ni, Cd, Co, Mn) .Some sites near to human and in
dustrials activities ,
and others near to agriculture activities , and others relatively far from pollution sources
has been selected. The results showed that the quantity of solid dust particles on leafs
trees and concentration of heavy metals in it such as (Pb, Ni, Cd, Co) increasing near the
industrials activities and dense traffic, and decreasing in the sites that relatively far from of
pollution sources. However Cypress trees attach solid quantities more than Pride of china,
following Rever red gum and Blue-leafed wattle and Oleander, and the Palm tree come in
the last.

During the last twenty years there was an increased interest to large extent in
crowing up the fruitful trees all over the world. That is a natural result of knowing its high
feeding value beside its being good source for income. Due to its economical importance,
there was variety of searches and studies which approached its farming.
SST satellite images analysis has showed many
characteristics for a lot of mesoscale eddies in the Eastern basin
of the Mediterranean Sea. In this study, the SST analysis is
focalised on the mesoscale eddies` formation at the Syrian coasts.
We are also interested by their characteristics for their influences
on the marine environment .
This study aims to analyze and define the role of knowledge
management in improving the financial performance of the commercial
banks operating in the Syrian coast, the study relied on the method of
approach Alastenbatih as a way to search, and th
e researcher depends on
the resolution as a tool for the study was designed based on the lookout
researcher on previous studies in this area, was distributed researcher
(187) to identify the sample items in the three administrative levels in
commercial banks under study, the study found the results pointed to a
correlation between knowledge management and financial performance
relationship, allowing the researcher to conclude viable conclusions and
use them as allowed him to provide recommendations are seen as
contributing to the improvement of the financial performance of
commercial banks under study and all similar banks organizationally and
technically.
The researcher addresses the role of enabling employees to increase job
satisfaction in public hospitals of the Syria coast. The research aimed to study
the role played by the dimensions of selected empowerment and to identify the
extent of their
impact on job satisfaction in the provinces of Tartous and
