Research summary
تناول البحث الحالي دراسة التركيب النوعي والكمي للأسماك المصطادة من مصب نهر القنديل وتوزعها خلال فترة الدراسة من كانون الثاني إلى كانون الأول لعام 2014. كما تم إجراء بعض القياسات المورفومترية لإصبعيات البوري والغريبة ودراسة وفرتها وتحديد أماكن وفترات وجودها في مصب النهر، فضلاً عن قياس الحيوية ونسبة نفوق هذه الأسماك خلال عملية الصيد والتداول. بينت النتائج أن مصب نهر القنديل يشكل موئلاً مثالياً لإصبعيات البوري بشكل خاص إذ توافرت على مدار العام، في حين توافرت إصبعيات الغريبة الرملية بشكل أقل. أظهرت إصبعيات كلا النوعين حيوية جيدة لحظة الصيد، وتبين أن الوقت المثالي لصيد هذه الإصبعيات هو الفترة الصباحية الممتدة من طلوع الشمس وحتى منتصف النهار. يمكن توظيف هذه النتائج في إمكانية صيد إصبعيات أسماك البوري والغريبة واستخدامها في عملية الاستزراع عوضاً عن استيرادها أو تغريخها اصطناعياً.
Critical review
دراسة نقدية: تعتبر هذه الدراسة ذات أهمية كبيرة في مجال الاستزراع السمكي، حيث تقدم معطيات تطبيقية يمكن أن تسهم في تحسين إدارة الموارد السمكية في سوريا. ومع ذلك، يمكن ملاحظة بعض النقاط التي قد تحتاج إلى مزيد من التوضيح أو البحث المستقبلي. على سبيل المثال، لم يتم التطرق بشكل كافٍ إلى تأثير التغيرات المناخية على وفرة الأسماك في مصب نهر القنديل. بالإضافة إلى ذلك، قد يكون من المفيد إجراء دراسات مقارنة مع مصبات أخرى في المنطقة لتحديد مدى تميز مصب نهر القنديل كموئل مثالي. أيضاً، يمكن تحسين منهجية البحث من خلال استخدام تقنيات حديثة مثل الاستشعار عن بعد لتحليل توزيع الأسماك بشكل أكثر دقة.

The objective of this article is describing the changes of the coastline shape during the time period extended between 1973-2014. the coastal zone is very special because it occur at the interface between the three major natural systems at the ear th surface atmosphere, ocean and land surface. Geomorphological factors operating in all three of these systems are responsible for shaping the coastal zone, and the interaction between the three different sets of processes makes the coastal zone an extremely dynamic one. At present, a wide range of tools and techniques are available to help us to study the evolution of coastline during the time intervals determined by the available data, and thus become our ability to predict future changes. improve our understanding of the geomorphological processes affect the coastal zone allow us to minimize their effects, and use this knowledge in the development of comprehensive coastal zone management planning.
In this study the concentration of (Cu, Cr, Cd, Fe, Mn, Ni, Zn , Pb ,V &Co) in some sedimentary columns and pore-water extracted from the estuary of Al-Kabeer alshemali river was determined during four seasons .the concentrations of these metals w ere determined using atomic absorption spectroscopy (AAS). The columns were cut into slices with 2cm of thickness ,the pore water at every slice was extracted using centrifugation (7000 r/min).the results showed that the concentration increased from surface(deep=0cm, rich of O2) up to the 4cm of deep ,then the concentration decreased in deeper slices (down of 4cm,deficiency of O2) and the concentration of Fe and Mn from high ranking ppm. The rest of the items were relatively lower ranking ppb, but Co, Cd and V were low. meat increased the concentration of all these elements in the spring and summer, compared with the values in the winter and autumn, due to increasing human activities on the one hand and the high temperature on the other hand, leading to increased activities of bacterial that leads to the decomposition of organic material that may increase the ratios of these elements in the pore water.
This study deals with the determination of total mercury concentration in the water taken from three sites on Al-Kabeer Al-Shemaly River ( near the industrial area and Al- Damat Lake, and 16 Tishreen Lake), also the effect of some physio-chemical p arameters including: DO, pH, T °C. of water in the three sites was studied. Results showed that the total mercury concentration was low in general, where the medium concentration in the three studied sites was 0.29 ppb and it was less than the permission level of total mercury in the surface water(> 10 ppb), the higher value of the medium concentration of total mercury(0.35, 0.31, 0.21)ppb was recorded in the Industrial Area, Damat Lake, then 16 Tishreen Lake, respectively. For the changes in the total concentration of mercury in the three studied sites during seasons of a year, was higher in Summer comparing with other seasons. The results showed positive correlation coefficient between the total mercury concentration and temperature, pH value, but it was negative with DO in Summer.
Al-Kabeer Al-Shemale river rises from Aqraa Mountain and coastal mountains, it is considered one of the largest rivers in the coastal area.Its catchment area is 1097 km2, and empties into the sea to the southern of Lattakia.The study aims to determin e the impact of climate change on the river discharge. Since the rainfall is the major factor in the runoff formation in the river catchment, the rainfall changes have been studied in climatic stations located within the catchment and its surroundings, and for a period of time exceeding thirty years. The study found that the general trend of rainfall change and runoff with time is decreasing, declining rainfall values ranged in the studied stations between (0.4-12.5) mm per year, and the runoff reached 0.08m3/s in the year. A mathematical equation, predict river discharge after knowing the values of daily precipitation, has been concluded.
This search was conducted during 2014-2015 growing season in Agricultural research station in Al Kraeim belonging to Al Salameah district in Hamah Provence in order to study the effect of plant density on; First, the phenological stages of lentil p lant calculated in day unit. Second, the seed productivity in a lentil plant calculated in g/plant, and then seed production in Hectares (Kg/ha-1).Lastly, percentage of seed protein content in seeds. In this study, three plant densities were used (200, 250, 300 seeds/m2, and was designed using Randomized Sectors in three replicates for each density. Results showed that; 1) The low density plants (200 seeds/m2) was significantly better than other densities (250 and 300 seeds/m2) in: Reaching 50% seed germination (19.4, 20.5 and 22.5 day continually) and in flowering stage (111.36, 113.6 and 114.7 day continually) and in maturation/Ripening stage (134.4, 136.6 and 137.7 day continually). Seed production per plant (1.553g/plant) in comparison by seed production of other densities (1.487 and1.376 g/plant). Percentage of seed protein (26.8%) in comparison by seed protein of other densities (26.3 and 26.19 %). 2) The higher densities (300 seeds/m2) was better in seed production in aria unit (1791.3 Kg/ha-1) in comparison by production of other densities (1492.7 and 1194.2 Kg/ ha-1).
