Atmospheric temperature increases after sunrise to reach its maximum at approximately ٢ hours from midday. The temperature variation curve agrees with the intensity curve of incident solar radiation on the earth surface, but with delay time (tow hour) proportional to the parameters atmosphere and materials. During eclipse of sun, the intensity of solar radiation decreased, and as a consequence, this affects many atmospheric processes, such as temperature of air and wind cycles. These changes can be studied as variations of solar radiation density, which occurs in the short time of the eclipse. These variations can be observed by a spectroscopic study, was the subject of the Damascus university scientific group to studying the total eclipse in Ain- Dewar, which is located at northeast of Syria on ١١-th of August ١٩٩٩. The variations happened in solar spectrum and in the earth atmosphere were recorded and discussed in detail. The recorded diagrams and spectrum were analyzed for the estimation of the magnitude of radiation energy, which was screened during eclipse. They result in the estimation of energy loss by the atmosphere and its parameters like temperature and wind movement. It was shown, that ٦٠٪ of the total solar energy were screened during eclipse, and this was sufficient to cause many changes in wind velocity and temperature of the atmosphere. Because of the eclipse line and neighboring areas considered to be connected with thermodynamic system, thus the energy changes will decrease in the atmosphere, Sowe didn’t calculate it.

Research summary
تتناول الدراسة المقدمة من سيوف والجغامي تقدير الطاقة الضائعة خلال كسوف الشمس الذي حدث في 11 أغسطس 1999 في سوريا باستخدام التحليل الطيفي. يوضح البحث كيف أن درجة حرارة الجو تزداد بعد شروق الشمس وتصل إلى ذروتها بعد ساعات قليلة من منتصف النهار، وكيف أن منحنى تغير درجة الحرارة يتوافق تقريبًا مع منحنى شدة الإشعاع الشمسي الساقط على سطح الأرض، مع تأخير زمني يبلغ حوالي ساعتين. خلال الكسوف، تنخفض شدة الإشعاع الشمسي مما يؤثر على العديد من العمليات الجوية مثل درجة حرارة الهواء ودورات الرياح. تم تسجيل هذه التغيرات ودراستها بواسطة مجموعة علمية من جامعة دمشق في منطقة عين ديوار شمال شرق سوريا. تم تحليل الطيف الشمسي والجو الأرضي لتقدير مقدار الطاقة الإشعاعية المفقودة خلال الكسوف، ووجد أن جزءًا كبيرًا من الطاقة الشمسية تم حجبه مما أدى إلى تغيرات ملحوظة في سرعة الرياح ودرجة حرارة الجو. تشير الدراسة إلى أن هذه التغيرات يمكن أن تكون مرتبطة بنظام الديناميكا الحرارية، وبالتالي لم يتم حسابها بشكل منفصل.
Critical review
دراسة نقدية: تقدم الدراسة معلومات قيمة حول تأثير كسوف الشمس على العمليات الجوية والطيف الشمسي، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل أن يتم توفير تفاصيل أكثر حول الأجهزة المستخدمة في القياسات وكيفية تحليل البيانات الطيفية. ثانياً، لم يتم توضيح كيفية تأثير التغيرات في شدة الإشعاع الشمسي على العمليات الجوية بشكل كافٍ، وكان من الممكن تقديم نماذج رياضية أو محاكاة لدعم النتائج. أخيراً، كان من الأفضل تضمين مقارنة مع دراسات سابقة في نفس المجال لتوضيح مدى توافق النتائج مع الأبحاث الأخرى.

This study was conducted to estimate the losses due to mastitis in Fedio Station –Syria, by using a direct microscopic method to determine the somatic cell count in bulk tank milk. About 52 milk bulk tank samples were examined weekly in one year.
In this paper the use of parabolic trough solar field to rise feed water temperature completely or partially according to brightness of sun is studied, in this way steam bleeding could be avoided variably. Results are analyzed according to Damascu s solar and climate data, efficiency is increased about 1.6 % and power raised 6 %.
Continuous calculations of evapotranspiration (LE) using eddy covariance method and energy budget were performed over more than one year above the heterogeneous canopy of an arid oasis ecosystem in the central Syrian desert. Irrigation practice wa s traditional flooding with a 28 days turn of water delivery. The work focuses on seasonal variations of energy budget over a 2 years period with emphasis on effects of rainfall, wind speed and radiative budget on evapotranspiration. Maximum evapotranspiration was only 5mm/day. Even under irrigation practices, winter rainfall seems to have an important impact on LE: comparisons of two situations in June 2002 and June 2003 showed an increase of 13% in values of LE/Rn-G. Maximum averaged hourly values of evapotranspiration were found for wind speed values closed to 3m/s. This suggests that when the evaporative demand from the air (or vapour pressure deficit (vpd) ) is increasing above a certain limit, the vegetation closes its stomata and reduces transpiration. Results from the energy balance closure showed significant differences in the slope of H+LE against Rn-G relationships between cold and hot month which was explained by specific radiative budget of desert areas.
Three identical gable-even-span greenhouses were designed, constructed and installed at the Agricultural and Veterinary Research Station of King Faisal University in order to produce cucumbers during the winter season. These experimental greenhous es were covered by ٠,٨mm thick fiberglass reinforced plastic. Two different solar heating systems were designed, built and employed to heat the ambient air temperature inside the greenhouses. The design of the first one was a surface heating system suspended and fixed on the southern side of the gable roof of one greenhouse. The second solar heating system was a solar panel, which was designed, built and situated outside of the other greenhouse.
The research aims to take advantage of the solar energy, as a free energy, to run a water pump powered by solar energy, and to study the effect of the intensity of solar radiation on the performance of this pump in Syrian coast conditions. This resea rch has explained the necessary mechanism for determining the capacity of the pump and the electric PV panels required for the work of the pump and the area of these panels. Studying the effect of intensity of solar radiation on the performance of water pump through studying the impact of pump altitude and solar radiation intensity on water flow range at experiment location. It demonstrated that the flow of the pump is going through two phases with the increasing values of solar radiation during the day. It was found that the increasing value of the flow of the pump before the value of (520W/m2) of Solar radiation was greater than that after (520W/m2) and this led to the loss of a part of the solar energy falling during the day, especially on sunny days, and the value of the loss was about (27%) of the total amount of solar energy falling per day.
