This research includes a detailed study of the daily and monthly changes to the intensity of total solar radiation in the city of Homs (34.75N °, 36.7 E °), and a direct measurement of the intensity. The study shows that intensity increases to maximum values in summer 1100w / m2, and drops to lesser values in winter 600 w / m2. The difference between the measured values in summer and winter is due to: a change in the inclination of the sun, and implicitly solar azimuth z. This angle is at its greatest in winter and the optical path is at the maximum. Thus, the processes of scattering and absorption increase. In summer, the inclination angle is at its lowest and the optical path is at the minimum. Thus, the absorption and scattering of solar radiation are at the minimum.

Research summary
تتناول هذه الدراسة تأثير العوامل الجوية على شدة الإشعاع الشمسي الكلي في مدينة حمص. تم قياس شدة الإشعاع الشمسي على مدار عام 2013 باستخدام جهاز بايرانومتر. أظهرت النتائج أن شدة الإشعاع تتغير يوميًا وشهريًا، حيث تكون أعلى في الصيف وأدنى في الشتاء. هذا التغير يعود إلى اختلاف زاوية ميل الشمس والمسار الضوئي. كما تبين أن العوامل الجوية مثل الغيوم والأمطار تؤثر بشكل مباشر على شدة الإشعاع من خلال عمليات الامتصاص والتبعثر. في ظروف السماء الصافية، تكون شدة الإشعاع أعلى بنسبة تصل إلى 48% في الشتاء و7% في الصيف مقارنة بظروف السماء الاعتيادية. توصي الدراسة بأهمية الاستمرار في قياس شدة الإشعاع الشمسي في مختلف الظروف الجوية لتوفير قاعدة بيانات يمكن العودة إليها في المستقبل.
Critical review
دراسة نقدية: تقدم هذه الدراسة معلومات قيمة حول تأثير العوامل الجوية على شدة الإشعاع الشمسي في مدينة حمص، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين بيانات من سنوات متعددة للحصول على نتائج أكثر دقة وشمولية. ثانيًا، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل الجوية الأخرى مثل التلوث الجوي والغبار. أخيرًا، كان من الممكن تقديم توصيات أكثر تحديدًا حول كيفية استخدام هذه البيانات في تحسين التخطيط البيئي والطاقة الشمسية في المنطقة.

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.
Modeling solar radiation consider one of important and helpful matter in researches in generation an electric power from solar cells. Researchers interested in this subject and put number of mathematical models to modeling solar radiation. In th is paper we will study one of this models (cloudiness degree model), then put algorithm for it, and based on it writing program using mathlab, then comparing this results with real value taken from position in Syrian Arabic.
Solar energy being one of the most promising alternatives, this because of its availability and low cost compared to other energies. The device that uses solar energy to desalinate saline water is called the solar still. The problem at the solar s till is reflected in its low efficiency, with the aim of raising it. This research presents a theoretical and experimental study for single-slope and single-basin solar stills.
The present study aimed at revealing the relationship between abnormal Family climate and some familial factors, as economic level of the family and educational level of the father and mother, to the Neuroticism among Public High School Students in Homs City. The sample of study consists of 290 students in some Public High School Students in Homs City. The researcher had used the following tools: The test of (abnormal Family climate) which Mario Rahhal had designed and the present researcher had re-normalized it to High School Students. And the scale of (Neuroticism) from the junior Eysenck personality Questionnaire which the present researcher had re-normalized it to High School Students.
The research aims to study the effect of weather (humidity - pressure - temperature) on the linear measurements between geodesic network points through the introduction of these factors directly on the Total station devices settings and get distanc es patched for that network has been based geodesic point (conducting field measurements necessary) within easy reach of the design requirements of the device ideal conditions in the study area (Trjano) in the province of Latakia, which we will adopt in the later stages to monitor landslides and thus all measurement cycles will be compare basic measurement cycle taking into account changes in ambient weather conditions in each measurement cycle for the reference measurement cycle.
