يركز هذا البحث على تحديد نزر بعض العناصر المعدنية الثقيلة (النيكلNi و الكادميومCd) في الرسوبيات الشاطئية البحرية لرأس البسيط (اللاذقية) خلال الفترة الممتدة بين خريف 2013 و صيف 2014 باستخدام جهاز الامتصاص الذري (Atomic Absorption Spectrophotometer: AAS) بين منطقتين جغرافيتين مختلفتين أحدهما مغلقة و الأخرى مفتوحة. تشير نتائج البحث إلى وجود ارتباط هام بين تغير تراكيز العناصر المعدنية المدروسة (Ni&Cd) و نوعية الرسوبيات و مواقع جمع العينات من جهة، و باختلاف مصادر التلوث من جهة أخرى. لوحظ سيادة للرسوبيات الرملية الناعمة مع كميات من الغضار في رسوبيات المنطقة المغلقة مع ارتفاع تراكيز كل من النيكل (755.50mg/Kg) و الكادميوم (71.30µg/Kg)، مقارنة مع المنطقة المفتوحة التي كانت أغلبية رسوبياتها رملية متوسطة مع انخفاض تراكيز النيكل (38.85mg/Kg) و الكادميوم (13.31µg/Kg).
This research focuses on determination the concentration of some heavy metal elements (Nickel Ni and Cadmium Cd) in the coastal water sediments of Ras Al-Basit (Latakia ) during the period that range between Autumn 2013 and Summer 2014 using the Atomic Absorption (Atomic Absorption Spectrophotometer: AAS) at two different (closed and open) geographical regions. The results of the research indicate a correlation monumental between the change in the concentration of studied metallic elements (Ni & Cd), the quality and sediment sampling sites on the one hand, and the sources of pollution on the other. It observed the rule of fine sand with minor amount of clay in the sediments collected from closed area; with high concentrations of both Nickel (755.50mg/Kg), and Cadmium (71.30μg/ Kg), compared with the open area while the majority of the sediments are medium sand with low Nickel and Cadmium concentrations (38.85mg/Kg; 13.31μg/ Kg).

In this research a sample of soccer coaches from the first class in the Syrian League soccer (20 coaches) were used to get a real evaluation of their knowledge and awareness about the physical changes that have occurred on the fitness elements of mod
ern soccer players, The modern physical changes in soccer play were also analyzed and estimated for the last forty years depending on a comprehensive analysis of the scientific researches and studies specialized in this field, this would assist coaches to take attention to these capabilities through the different stages of training in order to make them in a perfect construction in line with the requirements of competition.
The Results showed that the coaches could not distinguish between modern physical changes and their manifestation or appearance forms, which refers to lack of their information and familiar about these changes. There are many physical changes such as:
1.The total distance of 8-12 Km which estimated by 10% annually until 1985 and a remarkable constancy since 1985 until 2010
2.Running movements performed by a maximum speed ranging from 0 to 5 m
3.Soccer movements from 40-100 movement (jump- Tackling- shot ball and 1 vs. 1)
4.Requirements of each property differ according to the player position and the tactical task entrusted to him.
The research aimed at studying the impact of the most
important economic and social factors affecting the adoption of new
irrigation techniques، namely water collective management in ALGhab
basin in Syria .The research accomplished by taking a
si
mple random sample of 264 farmers .Because of the nature of
dependent variable which is dichotomous ،(1= adoption of water
collective management،0=otherwise)،The binary logistic regression
was used.
The aim of the study was to study the ability of the leaves of the figs (Ficus
retusa L.) and (Phoenix dactylifera L.) in the city of Tartous to accumulate the
lead elements (Pb), nickel (Ni).
This research investigates the actual beginning of experimental animation films and
their main directions. The research also reviews the most important pioneers of abstract
experimental animation in both Europe and the U. S. A. such as Leopold Surv
age, Viking
Eggeling and Hans Richter, on the one hand, and the most important film productions and
the techniques used, on the other. We move on after that to the most wellknown figures of
the pictorial school in Europe as Lotte Reinger, Berthold Bartosch and Alexander
Alexeieff.
The research moves on to take up the review of the contemporary experimental
directions which began in the early 1950's and continued up to the present time, the
directions which produced significant figures and experiments of paramount importance in
the history of animation , such as Walter Disney, Ivan Vano, Osamo Tezuka, Norma
Mclaren in addition to John Halas. These approaches shape the future of animation. The
present research sheds light on the significance of both previous (earlier) experiments and
the prospect of animation films.
The objective of this research is applying Factor Analysis for Studying the most
important economic factors affecting the number of employees within period 2000 till
2009 in Syria, to propose a methodological framework for constructing the integrat
ed
factor analysis model system (FAMS) that can be used as a decision support tool in
employment year examination and supervision process for detection of years, which are
experiencing serious problems. Sample and variable set of the study contains 17 economic
variables.
Study years (10 years during the period 2000–2009) and their economic variables.
Well known multivariate statistical technique (principal component analysis), was used to
explore the basic economic characteristics of the theses years, and discriminant models
were estimated based on these characteristics to construct FAMS. The importance of factor
analysis model system in employment year examination was evaluated with respect to
defining the non-employment years for deciding the most important employment policy for
reducing unemployment rates in future.
Results of the study show that, if FAMS was effectively employed within studied
years, It is possible in this case to identify weaknesses, according to the years that have the
number of employees is less than the overall average calculated over the period.
