تدل الدراسة أن معظم الدوريات الكيميائية البالغ عددها 1058 دورية يصدر عن31 % من دول العالم. و أن حوالي 92 % من هذه الدوريات يصدر عن ثلث هذه الدول فقط (20 دولة، 10 % من دول العـالم). و أن عـدد الدوريات المحكمة و نسبتها أعلى من نسبة غير المحكمة في جميع الدول التي تصدر عنها معظم الدوريات. كما أن عدد الدوريات المحكمة و نسبتها أكبر من غير المحكمة بحسب اللغات الرئيسة المستعملة في معظمها.
Our study shows that only 31 % of the world issue the chemical periodicals /1058/. Out of the 1058, 92 % are issued by the third of these countries (20 countries which is equal to 10 % of the world), in which the number of refereed periodicals is higher than the unrefereed ones. The ratio was the same when the periodicals were categorized by the spoken language.

The paper discuse the development of self and establishment's descriptions
of chemical periodicals in two decades. It focuses on the new procedures
followed to publish a scientific paper manuscript using the online deposit which
used now in most o
f the publisher's websites, and this in comparison with the
old printing and publishing procedures and techniques. Optical typeset and
electronic communications effects on self description have been discussed with
the effects of economic, financial, environmental and place required for
storage. The number of manuscript copies, which was one of the main
conditions for publishing, has been decreased and the requirements of chemical
materials have been changed. The paper concentrates on the chemical
periodicals which first published between 2003 and 2007.
The paper shows the reasons for the institutional evaluation of the
international scientific periodicals. The evaluation factors, criteria, indicators
and quality have been discussed. The development, cease and requirements of
continuity, as well
as contemporary realities are also presented. With some
aspects of the characterization of the qualitative evaluation of journals such as
refereed, prestigious, and authoritative, and review the features of the
development of quantitative digital indicators of periodicals and its
classification, and in particular those supporting factors, to evaluate the
journals in terms of numbers, date of measurement, standards, tools, and
databases, and citation frequency and measurable indicators. Impact factor
and its measurable indicators such as the average impact factor, immediate
indexing, and half-life citation are studied.
The big value of dams in the Syrian coast comes from using them for irrigation and sometimes as source of potable water. This study aimed to determine some chemical indicators of water quality in Lattakia dams during ten years (2002-2011). The
conce
ntrations of ions (Cl-1, SO4-2, NO2-1, NO3-1, PO4-3, K+1, Na+1) in five dams (Balloran, 16 Tishreen, Al-thawra, Alsafarkia and Alhweez) were studied. The results indicated that most of the ions showed significant difference in concentrations during 2002-2011.The ions concentrations in most studied dams increased. The increase related to characteristics of dams (location, capacity, the activities located around the dam…).
The aim of this research is to study chemical and physico-chemical characteristics of
Akawi, Medaffarah, Shankalish and Sorkeh cheeses for their identification and comparison
with some internationally widespread cheeses. Several chemical analyses were performed
on samples collected from different region famous with these products.
This research was conducted in Agriculture College (Food Science Dep.,
Damascus U university). The purpose of this research was to evaluate Cherkes
Cheese by determination some Chemical and microbial properties for 40
samples collected randomly fr
om different places Damascus and country sides.
The results showed very deferent changes in Chemical properties. The acidity
ranged between (0.25 - 0.54%), moisture content (38 - 56%), and total dry
matter (44 - 62.7%). Results also showed that all samples were rejected by
(Syrian Normal Standard)for fat content in dry matter (20 -33%). Fifty percent
of samples were rejected for their content of sodium chloride which was
(1.2 - 4.3%). Results also showed that samples were free of Salmonella and
there was no rejection for existence of Staph. aureus but 37.5 % and 10% of
samples were rejected by (Syrian Normal Standard)as per content of coliform
and E.coli, respectively.
