This paper introduces an integrated study concerning the technical and economical sides for supplying the electrical loads of a rural isolated society or small isolated village represented in Almazraa village relevant to Nawa Town located at the north western of Daraa Governorate at a distance of about 30[Km]. The followed methodology of this study aims at the comparison between two states required electrical loads according to special scenario of each state, the first scenario represents the feeding of special loads of a daily lifetime activity performed by the inhabitants of this village representing a case of typical rural society, and the second scenario adding the loads of irrigation of surrounding agricultural lands to the first scenario. For supplying the required loads then making a comparison between two choices, the first choice is the usage of solar cells as a renewable energy source, while the second choice is the usage of diesel generation units as a traditional energy source. This paper included the preparation of the mathematical model of previous system then to determine the volume of this system for each of the two cases of loads and the previous two choices of energy sources. The preparation of computer programs of previous study because of the easiness of projecting them two similar cases. The research also included an economical study of the previous cases then coming through them into the computation of fixed cost or construction cost, running cost and the annual cost and then estimating the production cost of Kilo Watt-hour and to identify the more economically feasible of choice. Then to complete this study by focusing on the volume mass of contamination wastes caused by the daily work of diesel units and presentation of the economical importance for the usage of solar cells especially in the isolated areas and in the rural and agricultural societies as economical choice and without an environmental damaging wastes.

Research summary
تقدم هذه الدراسة تحليلاً فنياً واقتصادياً شاملاً لتغذية الأحمال الكهربائية لمجتمع ريفي معزول، ممثلاً بقرية المزرعة في محافظة درعا. تهدف الدراسة إلى مقارنة خيارين لتوليد الطاقة: الأول باستخدام الخلايا الشمسية كمصدر للطاقة المتجددة، والثاني باستخدام وحدات توليد الديزل كمصدر تقليدي. تم إعداد نموذج رياضي لتحديد حجم النظام المطلوب لكل حالة من الأحمال، وتم تطوير برامج حاسوبية لتسهيل تطبيق الدراسة على حالات مشابهة. تضمنت الدراسة حساب الكلفة الثابتة والمتغيرة والسنوية، وتقدير كلفة إنتاج الكيلووات الساعي لتحديد الخيار الأكثر جدوى اقتصادياً. كما تم تسليط الضوء على حجم التلوث الناتج عن استخدام وحدات الديزل، وأهمية استخدام الخلايا الشمسية كخيار اقتصادي وبيئي في المناطق المعزولة.
Critical review
دراسة نقدية: على الرغم من أن الدراسة تقدم تحليلاً شاملاً ومفصلاً لتغذية الأحمال الكهربائية باستخدام الخلايا الشمسية ووحدات الديزل، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة تعتمد بشكل كبير على البيانات المناخية والجغرافية المتاحة، والتي قد تكون غير دقيقة أو غير محدثة. ثانياً، لم يتم تناول تكاليف الصيانة والتشغيل بشكل مفصل، مما قد يؤثر على دقة التقديرات الاقتصادية. ثالثاً، الدراسة تركز بشكل رئيسي على الجوانب الاقتصادية والفنية، دون التطرق بشكل كافٍ إلى الجوانب الاجتماعية والبيئية الأخرى التي قد تكون مؤثرة في اتخاذ القرار النهائي. وأخيراً، يمكن أن تكون هناك حاجة لمزيد من الدراسات التجريبية لتأكيد النتائج النظرية وتطبيقها على نطاق أوسع.

The current study handles what related to the Information Society including aspects of concept, origin, essential terms that have been circulating on this concern, characteristics, in addition to the most significant theories of information society that have hypnotized the scholars of various backgrounds and specialties the most obvious of which are the sociologists, economists, and the technologists, not to mention the economical and technological essentials and their impact on such a society. This study concludes with a constellation of findings most important of which are: information become among the basic sources that obviously affect various sectors of life: economical, social and cultural. They are however looked at as a resource that could be utilized as a commodity. The improvements in the field of information technology has led to dividing societies into three constituents, as follows: sharing societies, affiliated societies and secluded societies.
Husbandry of the medicinal and aromatic plants in general and “Rosemary” in particular is considered of the alternative economical husbandry that flourished recently in Syria due to the availability of the natural and environmental conditions there to; in addition to the good economical yield thereof. Interest, encouragement, development, and expansion of such husbandry are considered of the most important targets set for the future strategy of agricultural development in Syria. This Research has targeted to the realization of the following purposes : 1- Analysis of the costs of Rosemary production in Lattakia Governorate. 2- The economical evaluation for Rosemary production in Lattakia Governorate. The research concluded to the following: 1) The achieved annual net profit of one dunum planted with Rosemary in Lattakia Governorate has amounted to SYP /200799.48/. 2) The farming revenue of one dunum planted with Rosemary in Lattakia Governorate has amounted to SYP /206901.84/. 3) The total Economical Feasibility from Rosemary husbandry in Lattakia Governorate has amounted to 3,02
In this paper, we present a system design of the photovoltaic pumping to provide electrical and economic comparison between two different energy supply systems: the first depends on the PV panels, and the second depending on the public grid. farm area study in the eastern countryside of Homs with the aim to supply water for irrigation and drinking.
The paper presents a research hybrid systems (hydrogen-photovoltaic) for a mobile phone station in an area far from the network or can be mobile in a desert area. This study investigates and design a renewable energy-based energy system for a mobi le phone station.

This article deals with the degradation of solar cells induced by electron irradiation. We have exposed GaAs solar cells to different doses of accelerated electrons to create defects, which play an important role as non-radiative recombination center s. We try to achieve the same conditions to which the solar cells are exposed to in outer space. We have studied the variation of the photovoltaic characteristics of these cells versus electron flux. We found out that the open – circuit voltage of GaAs solar cells varies with the electron irradiation dose j, which we varied in the interval: 2x1012 elec.cm-2 < j <5x1015 elec.cm-2 and we found out that: Voc = 1.22 - 0.04 log j V Voc = 2.39 - 0.12 log j V for both, the diffusion and the recombination zones respectively. The density of the short-circuit current has been measured and we found that the current varies with the electron irradiation dose, according to the relation: Jsc = 62.47 - 3.45 log j mA.cm-2 The degradation of solar cells appears from the decrease of the maximum power when () increases.
