تناول بحثنا دراسة المقاومة الموجودة عند أشجار الأكاسيا القريبة من اتوستراد جبلة - بانياس، و ذلك من خلال دراسة الثغور و توزعها على سطحي الورقة العلوي و السفلي. و دراسة تركيز اليخضور و شدة التركيب الضوئي و مقارنة النتائج بين المنطقة الملوثة و منطقة الشاهد. بينت النتائج بأن عدد الثغور ينخفض في المنطقة الملوثة مقارنةً بالشاهد حيث يلعب هذا النقصان دوراً في تخفيف الأذى الناتج عن ملوثات الهواء الغازية و انعكاس ذلك على شدة التركيب الضوئي و الأصبغة اليخضورية.
The present research was conducted to study the resistance of Acasia tree which were near to Banias- Jableh freeway. This study was performed by study the stomata and its distribution on the upper and down leaf surfaces. Also, a concentration of chlorophyll and a severity of photosynthesis, then compared the results between the polluted region with the control one. Results showed that a number of stomata decreased in polluted region compared to the control one, where this reduction play a role in reduce the injury resulting from gas air pollutants, and this reflexes on the severity of photosynthesis and the chlorophyll.

Research summary
تناول البحث دراسة مقاومة أشجار الأكاسيا Acacia synophyla لملوثات الهواء الغازية بالقرب من أوتستراد جبلة-بانياس. تم التركيز على دراسة الثغور وتوزيعها على سطحي الورقة العلوي والسفلي، بالإضافة إلى قياس تركيز الكلوروفيل وشدة التركيب الضوئي. أظهرت النتائج أن عدد الثغور انخفض في المنطقة الملوثة مقارنة بمنطقة الشاهد، مما ساهم في تقليل الأضرار الناتجة عن ملوثات الهواء الغازية. كما لوحظ انخفاض طفيف في تركيز الكلوروفيل وشدة التركيب الضوئي في المنطقة الملوثة. أوصى البحث بمتابعة الدراسات المتعلقة بقدرة أشجار الأكاسيا على مقاومة ملوثات الهواء وتعزيز الأبحاث في هذا المجال للحفاظ على البيئة وتحسين نوعية الهواء.
Critical review
دراسة نقدية: يعتبر البحث خطوة هامة في فهم تأثير ملوثات الهواء على النباتات ودور الثغور في مقاومة هذه الملوثات. ومع ذلك، يمكن تحسين الدراسة من خلال توسيع نطاق العينات لتشمل مناطق مختلفة ومتنوعة بيئيًا. كما يمكن تعزيز النتائج بإجراء تجارب إضافية تشمل أنواع نباتية أخرى للمقارنة. بالإضافة إلى ذلك، يمكن استخدام تقنيات حديثة لتحليل البيانات بشكل أكثر دقة وتفصيلًا. من المهم أيضًا تضمين تأثيرات الملوثات على المدى الطويل وتقييم الأثر البيئي الشامل لهذه الملوثات على النظام البيئي ككل.

كيف تم قياس شدة التركيب الضوئي في الدراسة؟
تم قياس شدة التركيب الضوئي عن طريق ربط ورقة نباتية طازجة بخيط ووضعها في حوجلة زجاجية، ثم قياس ارتفاع قطرة ملونة في أنبوب زجاجي نتيجة انطلاق الأوكسجين من الورقة أثناء عملية التركيب الضوئي.

We discussed the importance of studying the trichomes award in
olive trees, leaves and its role in the resistance to these trees against
pollution resulting from the Banias refinery intake, through the
study of their density and distribution on a
superficial paper and
examine the concentration of chlorophyll in the leaves, and
comparing the results between the contaminated areas and the
control area .
Results showed that the density of the trichomes play a role in
protecting the ports of entry into force of pollutants into the plant
tissue, and its impact on the pigments of photosynthesis, and thus
the process of photosynthesis.
The events, the developments and the international changes are based on the tracks that always deviate as the result of wills struggle between the forces and states. In the sense that the political crises that countries face means a set of interactio
ns among the forces that have conflict which may reach to a confrontation. So we must be aware of the political and economic changes, according to the scientific methods to understand what threatens the interests of the states. Many of the sequential crises throughout history are resulted from the use of the power which is based on the object of the available resources. Therefore, the power is the practical exercise and the political investment abroad and that happens through diplomacy or war so that the state can determine its objectives, and decide what to choose among those of power tools.
The forces and the states have seek to own the overall power in order to be the motivator of the political units within the framework of the international community. There are countries which benefit from the wars set in their agendas in advance to achieve the aims of their policy. War is still an essential tool for states, governments and groups to achieve their interests through direct conflict, or through the threat of sanctions, or through aids, including the so-called soft power, and sometimes through the form of international legitimacy, including the emergence of the term "fighting terrorism" and what accompanied it of global changes led to politically, militarily, economically and technologically submission to the powerful nations.
The concentrations were determined of the most basic air pollutants
(SO2, H2S, CO, O3, NOx, TSP, PM10, PM2.5) in some vital areas in
the Tartous city of and its surroundings using a mobile unit to
measure air pollutants.
The research aims to identify the role of organizational culture in reducing resistance to
change of the employees through a study of the relationship between the dimensions of the
organizational culture, and the reasons of resistance change by emp
loyees working in Lattakia City
Council. To achieve the objectives of the research, a questionnaire was designed and distributed to
(343) employees in Lattakia City Council, (315) questionnaire were complete and valid for
statistical analysis, with a response rate of (91.84%). Relying on multiple regression, the following
results were reached:
1. There is a strong inverse relationship which is statistically significant between the
elements after the containment and interdependence of (empowerment, staff development,
teamwork and participation), and a reeducation of the resistance of workers to change, wherever
after containment and coherence elements are available, there is a decline in the causes resistance
of workers to change.
2. There is strong inverse relationship that is statistically significant between the elements
after the consistency and uniformity of working (core values, agreement, coordination and
integration), and a reduction of resistance workers to change, i.e. when elements after consistency
and homogeneity are availed, they lead to a decline in the causes of workers resistance to change.
3. There is strong inverse relationship which is statistically significant between the elements
of the human aspects (respect and appreciation, justice, encouragement achievement, and social
welfare), and the reeducation of workers resistance to change, i.e., whenever there are elements of
the human aspects, there is a decline of the causes of workers resistance to change.
4. There is strong inverse relationship which is statistically significant between the elements
after the organizational climate of (administrative practices, rewards, communications, and
surveillance system), and the reduction of workers resistance to change, i.e., wherever after the
organizational climate elements are available, there is a decline in the causes of workers resistance
to change.
This research was aimed to assess the pollution from Tartous Cement Factory of
some heavy metal by using of the bark of olive trees and Lichens as Bio-indicators. The
olive trees was chosen as that predominant vegetation type in the study area. Bar
k samples
of olive trees and the lichens were collected from several villages surrounding the Cement
Factory at different distances (1-2-3-4-5-6-7) km from the center of the Cement Factory in
the eastern and north-eastern region of the Cement plant (where the prevailing winds in the
region is western and southern Western).
The results showed that the concentration of heavy elements in the bark of olive trees
and lichens (ppm) take the same trend even thought there are differences in concentration
between them by the overall average for all sites was as follows: iron > manganese >
copper > lead. We note the high concentration of iron in bark of olive trees compared to
lichens, but the rest of the elements it was statistically identical. The results also showed a
significant correlation between the concentrations of manganese element in each of the
bark and Lichens, and the existence of a negative correlation between the concentration of
manganese and distance for both Lichens and bark. Concerning the altitude above sea level
the results showed existence of significant and negative correlation with all of Iron,
Manganese and Lead in Lichens.
