يدرس البحث إمكانية تحسين مردودية عملية تجفيف المنتجات الزراعية في (المجفف الشمسي-بيت بلاستيكي), و ذلك بإجراء تعديلات على تصميم المجفف الشمسي, حيث تم توسيع وحدة التخزين الحراري ضمنه, و وضع ساتر عزل حراري فوق السطح الشفاف الزجاجي لتقليل الضياعات الحرارية ليلا, و إضافة مروحة نابذية فوق نفق التجفيف لزيادة سرعة عملية تجفيف أوراق التبغ بزيادة تدفق هواء التجفيف الساخن المار من خلالها. و قد أجريت تجارب تجفيف نماذج من التبغ السوري (البرلي و البصما) في المجفف الشمسي المعدل في مركز أبحاث التبغ في الرميلة في اللاذقية خلال شهر حزيران من عام 2013. حيث تمت عملية التجفيف لنماذج تبغ البرلي و البصما المحميّة بشكل كامل من المطر و الحشرات ضمن المجفف الشمسي خلال أربعة أيام لتبغ البرلي و ثلاثة أيام لتبغ البصما. و كانت جودة أوراق التبغ المجففة ضمن المجفف الشمسي و نوعيتها جيدة.
This research study the improvement of the performance of drying the agriculture products in (solar dryer-greenhouse), therefore; the design of the solar dryer had modified. The thermal storage unit became bigger, and the glass transparent roof covered by thermal isolation sheet to reduce the thermal losses at night, a centurial fan was put on the drying tunnel to increase the speed of drying of Tobacco olives by increasing the hot drying air flue. The solar dryer tested in the tobacco researches center in Ramilah in Lattakia by drying samples of tobacco(Brly, Bassma) during the period of June,2013. The dried products in the solar dryer were completely protected from rains and insects, and the dried products are of high quality, The tobacco(Brly, Bassma) being dried in the dryer in four and three days, respectively.

In this study، a traditional air source heat pump was modified by adding secondary
evaporator within hot water tank which acted as a water heat source of the heat pump. We
made the heat pump to run alternatively either using surrounding air heat or
water heat
gained from solar power.
We have done experiments during five months starting in December of 2014 until
April 2015. Temperature and pressure were measured at specific points of the cycle. Then
we defined the enthalpy at each point for both cycles using EES software (which is a
software to simulate thermodynamic elements)، and calculated the amounts of heat gained
in the evaporator، heat charged from the condenser، compressor work، coefficient of
performance ، and electrical power consumed by the compressor.
Then we made a compare between the two cycles and found that the improvement
ratio in of the modified cycle to the traditional cycle was 77.07%، and the reduction
ratio in electrical power consumed by the compressor of the modified cycle was 33.54%.
In this research, an absorption cooling system of nominal capacity 10 [kW] has been built and tested; it works by different sources of heat and by different working fluids, it is equipped with adequate sensors for measuring temperature, flows and pre
ssures in multiple locations. The features of operating the machine for air conditioning has been determined, analyzed and discussed with the working fluid “water-Lithium Bromide” by different boundary conditions. The results of experiments proved the possibility of the work of solar absorption cooling machine continuously at the heating temperature of the generator of 60 [°C] producing cold water in the evaporator at a temperature less than 10 [°C] with a coefficient of performance 0,5 and this enables us to use Simple and cheap flat solar collectors for the operation of the machine.
The research aims to identify the reality of the work of tobacco workers union in
Jablah Department, in order to stand on their success in protecting the interests and rights
of members of workers, and to provide the necessary services to them, as
well as to
identify their role in improving the performance of workers in Jablah department.
The researcher has prepared and distributed a questionnaire on the research sample,
which amounted to (77) were distributed among workers (15) in the office of trade union
members and (62) a member of the guild. Data were using SPSS statistical analysis
software.
In this work, we calculated the gamma energy (Eg) of scattered photons in Compton effect, as a function of scattering angle,q. We have used in this work gamma radioactive source, Cisium-137 (137Cs); its intensity is 3,33.105Bq, where it has been orie
nted towards an aluminum scatterer. The results obtained showed that the energy variation of the scattered photon on an aluminum scatterer, as a function of the scattering angle, is in good agreement with the values obtained by theoretical equation.
Given the economic importance of tobacco in the Syrian coast, which is one of the most important agricultural crops which contribute to raising the level of economic life.
In this research we focused on studying the varieties of tobacco produced in
the Syrian coast by studying the quantities produced of each item and the costs and revenues of the production and profitability of production and its role in agricultural GDP during the period (2000-2011), which gives a clear picture of the impact on economic development, through applying multiple regression to examining the contribution of various tobacco varieties produced on the Syrian coast agricultural GDP, and is based on data collected from the General Organization for tobacco and cigarettes company in the governorate of Latakia. One of the most important findings:
1. Type Verginia achieved higher profitability during the period (2000-2011), while the lowest type Zegreen profit achieved during the same period.
2. - Shak Elbent followed by Verginia and Tanbak are considered the most important types and the most contributable to the Agricultural Domestic Product (ADP).
3- There is no impact of the profitability of Basma and Prilep and Gernata and Zegreen and Berly types produced in the Syrian coast on the Agricultural Domestic Product (ADP).
