The Sediment microbial Fuel Cell (SMFC) has been studied in terms of electrical power generation, and water treatment. With the aim to design the Sediment Microbial Fuel Cell (SMFC), the sediment was brought from the Al-sonobar River bed, where it was described to indicate the organic content and nutrients in it. The cell was equipped with a surface aeration system and started working in it. Where it monitored the electrical current and water pollution indicators over time. Later the aeration mode was changed and previous measurements of electricity generation, water pollution indicators were carried out, and compared with the previous stage. Results of the first mode of aeration have shown that the greatest value for Short Circuit Current (ISC) was (0.905) mA while the greatest value for Open Circuit Voltage (VOC) was (0.390) V. While a rise in current and voltage values was observed in the second mode of aeration, in which the greatest value of Short Circuit Current was (1.240) mA, and the greatest value of open circuit voltage (0.430) V. When the circuit has been connected to an external resistance R=100 Ω, the values for current, voltage, current density and power density were (0.805) mA, (0.084) V, (3.18) mA/m2, and (0.269) mW/m2, respectively. For water analysis, an increase in pH values of 8.90 was observed. The efficiency of removing of Chemical Oxygen Demand (COD), phosphates, nitrates and Total Dissolved Salts (TDS) has also increased, reaching: 72.11%, 62.70%, 35.60%, and 30.61%, respectively.

Research summary
تناولت الدراسة كفاءة خلايا الوقود الميكروبية لطبقة الرواسب في توليد الطاقة الكهربائية ومعالجة المياه. تم تصميم خلية الوقود الميكروبية باستخدام رواسب من نهر الصنوبر، وتم تزويدها بمنظومة تهوية سطحية. أظهرت النتائج أن النمط الأول من التهوية حقق أعلى قيمة لتيار الدارة القصيرة (0.905 mA) وأعلى قيمة لجهد الدارة المفتوحة (0.390 V). بينما أظهر النمط الثاني من التهوية ارتفاعًا في قيم التيار والجهد، حيث بلغت أعلى قيمة لتيار الدارة القصيرة (1.240 mA) وأعلى قيمة لجهد الدارة المفتوحة (0.430 V). كما أظهرت النتائج كفاءة عالية في إزالة الملوثات من المياه مثل COD والفوسفات والنترات والأملاح المنحلة الكلية. تم الوصول إلى كثافة تيار ناتج (3.18 mA/m²) وكثافة طاقة (0.269 mW/m²) في النمط الثاني من التهوية. خلصت الدراسة إلى أن خلايا الوقود الميكروبية لطبقة الرواسب يمكن أن تكون حلاً مستدامًا لتوليد الطاقة ومعالجة المياه، مع توصيات بتطوير النموذج الحالي واستخدام أنواع جديدة من الأقطاب الكهربائية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو تحقيق استخدام مستدام للطاقة ومعالجة المياه. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين تحليل اقتصادي شامل لتكلفة إنشاء وتشغيل خلايا الوقود الميكروبية مقارنةً بالطرق التقليدية. ثانيًا، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية المختلفة مثل درجة الحرارة والملوحة على كفاءة الخلايا. ثالثًا، كان من الممكن توسيع نطاق الدراسة ليشمل أنواع مختلفة من الرواسب والمياه لتعميم النتائج. وأخيرًا، يجب إجراء تجارب طويلة الأمد لتقييم استدامة وكفاءة النظام على المدى البعيد.

This study concentrates on two basic problems:i)- Increasing of power efficiency in Industrial premises to reduce the energy needed for product unit without any impact on the production level . To achieve this goal, lighting system should be opera ted in a certain condition, capacitor banks for power factor improvement should be installed, and energy losses of distribution transformers should be reduced.
The research aims to study the effect of the distribution water on Proton Exchange membrane fuel cell (PEMFC), and the relationship of membrane thickness and the effects of changes in thickness depending on the amount of water contained within the membrane. The research also aims to change the effect of humidity on the effectiveness of the membrane proton through the diffusion coefficient and the coefficient of the flow electral osmotic. The research includes the study of humidity on the cell performance at constant temperature and its effect on the input interface.
The objective of this research to study the chemical composition and microbial load for some types of pies by performing various chemical and microbial analysis of samples collected, from different parts of the Syrian coast which are famous for its production. This study showed a large variation in the chemical composition of samples by type of the pastry and place brought from, for example, the proportion of dry matter for peppers and chard pies collected from Banias was, 75.71% and 44.90%, respectively, and the percentage of dry matter was 73.88% and 76.18% and the proportion of protein was, 17.76% and 24 .88% for cheese pies collected from Tartous and Latakia 1, respectively. This study indicated that all the pies contain a high percentage of fat [the lowest in chard pies (17.64%) and the highest in cheese pies (38.12%)]. Furthermore a high percentage of sodium was found (the highest in cheese pies 15.31 mg / 100 g and lowest in pepper pies 7.82 mg / 100 g). The study also showed that these meals meet international standards in terms of content of lead, cadmium, Nevertheless they are poor in fiber content except for chard pies which were the most balanced in terms of components, making it the best type of pies in nutritional aspect. Finally, the results showed that the microbial load was too high, as the total census of bacteria was higher than 105 and the total census of yeasts and fungi was higher than 102. In addition, all pies are not conformed to the Syrian legislation. The study also showed absence of E.coli and St. aureus of all samples.
Batteries are energy storage devices that are particularly useful for powering small portable devices like phones, laptops and entertainment devices as well as mobility devices that travel over the earth's surface, through water and air. During the night, or during a period of low solar irradiation, energy is supplied to the load from the battery in solar electrical Power Systems, and that provides Continuity of power supply, and on the other hand boosts the Reliability of the system.
