تضمن البحث دراسة للتغيرات اليومية و الشهرية لشدة الإشعاع الشمسي الكلي في مدينة حمص عام 2013, و ذلك بالقياس المباشر لهذه الشدة، بينت الدراسة أن الشدة تتغير لتأخذ قيماً عظمى في الصيف و قيماً صغرى في الشتاء، و يعود الاختلاف في القيم المقاسة صيفاً عنها شتاءً لاعتمادها على تغير ميل الشمس و ضمناً زاوية السمت الشمسية, تكون هذه الزاوية أكبر ما يمكن شتاءً و المسار الضوئي أعظمي ، فتزداد عمليتا التبعثر و الامتصاص، أما صيفاً فتكون زاوية الميل أصغر ما يمكن و المسار الضوئي أصغري ، و امتصاص الإشعاع الشمسي و تبعثره يكون أصغرياً.
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.

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.
