The present study aims at designing a promising Microbial Fuel Cell (MFC) to utilize wastewater in order to generate electricity. Two types of salt bridge have been used in MFC (KCl and NaCl). The maximum electricity generation with 1M KCl and NaCl has been 823 and 713 mV, respectively. Varied salt concentrations (0.5M, 1M, 2M, and 3M) of salt bridge in MFC have been analyzed with different factors like temperature, type of electrode, configuration, and surface area of electrode being studied. The optimum temperature is found to be 32Co, with the optimum type of electrode being graphite rod, while the optimum configuration and surface area of electrode is graphite plate with surface area of 183.6 cm2. Artificial Neural Network (ANN) has been employed to predict voltage production of MFC and compare it with the experimental voltage. Multiple correlation methodology has optimized the voltage production with the correlation coefficient (R2) being 0.999.
The idea of research is the detection of gases using the transmitter and receiver system for electromagnetic radiation in the IR region using the optical absorption method. As a result of the interaction of the light with the gas molecules can be detect and measure gas pressure adoption absorption method. It was chosen best absorption band between (1.4-1.6) um at the wavelength 1.5 um to build a sensor for accurate measurement of ammonia gas which is characterized by precision, where he was the measuring pressure range (1-6) bar. The importance of the oil industry has been focusing on this kind of scientific research for the detection of ammonia gas.
The main purpose of this work is to find not canonical equivalence to category and morphism of diffeomorphism from smooth manifold category with Fundemental Fibre Bundle denoted by groupoids morphism and denoted P.
الهدف الرئيسي من هذا البحث هو حساب الضرب التنسوري لأغطية اسقاطية تبولوجية للزمر التبولوجية بعد أن وضحنا ليس كل زمرة تبولوجية تمتلك غطاء اسقاطي تبولوجي معتمدين بذلك على صفات الضرب التنسوري للزمر التبولوجية الجبرية وعلى ادخال الصفات التبولوجية التي تتناسب مع التركيبة الجبرية تبولوجيا ً من خلال تعريف الزمر التبولوجية ثم الاسقاط على تلك الزمر التبولوجية حيث أن الزمرة التبولوجية تسمى زمرة اسقاطيةً تبولوجية اذا كان لكل تشاكل زمري تبولوجي شامل ولكل تشاكل زمري تبولوجي f: q ¾® B يوجد تشاكل تبولوجي f ': q ¾® A بحيث يجعل المبيان الاتي ابداليا ً
