Research ArticleOpen accessIn the abstractExperimental Investigation of Single Pass, Double Duct Photovoltaic Thermal (PV/T) Air Collector with CPC and FinsM. Ebrahim Ali Alfegi, Kamaruzzaman Sopian, Mohd Yusof Hj Othman, Baharudin Bin YatimThe temperature of photovoltaic modules increases when it absorbs solar radiation, causing a decrease in efficiency. This undesirable effect can be partially avoided by applying a heat recovery unit with fluid circulation (air or water) with the photovoltaic module. Such unit is called photovoltaic/thermal collector (pv/t) or hybrid (pv/t). An experimental investigation of a solar air heater with photovoltaic cell … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,987 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy of Benthic Fauna in the Discharge Lagoon of a Shrimp Farm With Special Emphasis on the PolychaetesLuis Rafael Martínez Córdova, Luis Fernando Enríquez OcañaA study of benthic fauna, with special emphasis on polychaetes, was made in the discharge lagoon of an experimental shrimp farm and a pond of the farm. The discharge lagoon was divided into three sections and stocked with shrimp at low density (6 Pl/m2). Neither formulated feed nor fertilization was used in these sections. The control pond was stocked with … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 6,680 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptical Properties and Sugar Content Determination of Commercial Carbonated Drinks using Surface Plasmon ResonanceW. Y.W. Yusmawati, H. P. Chuah, M. Y.W. MahmoodIn this study, an optical sensor based on Kretschmann SPR technique was used to detect the sugar content in commercial carbonated drinks. Three samples of carbonated drinks labeled as "Coke", "100 Plus" and "F&N Orange" have been chosen for angle scan SPR measurements. All the measurements were carried out at room temperature using He-Ne laser beam (632.8nm, 5mW) as a … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2007 · 8,784 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSome Basic Reactions in Nuclear FusionRelly Victoria Virgil Petrescu, Aversa Raffaella, Samuel Kozaitis et al.Over time it has advanced the idea that the achievement of a hot nuclear reaction can require tens or hundreds of millions of degrees. Precise calculations clearly indicate a much higher temperature. At least 10 million degrees are necessary for 1 keV in thermonuclear reaction. At 400 keV it needs a temperature of 4000 million degrees to occur the hot … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 20 Jul 2017 · 8,880 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Innovative Farm Scale Biogas/Composting Facility for a Sustainable Medium Size Dairy FarmA.E. Ghaly, M. Al HattabApproach: The amount of energy related costs as a portion of the total farm operating cost can be as high as 29% and the continuing increase of the real cost of energy related farm input has been one of the major factors impacting the cost of agricultural production. However, agricultural has the potential of replacing some of the purchased energy … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Jan 2012 · 9,320 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffects of Light Exposure and Nitrogen Source on the Production of Oil from Freshwater and Marine Water MicroalgaeMariam Al Hattab, Abdel GhalyThe biomass yield and oil content of Chlorella saccharophila (freshwater) and Tetraselmis suecica (marine) microalgae were investigated using various nitrogen source (ammonium nitrate, ammonium phosphate, ammonium sulfate and combination of nutrients) at various light durations (9, 16 and 24 h). NaHCO3 was used as the carbon source. The nitrogen concentration, temperature and pH were maintained at 70 mg/L, 22°C and … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 8 Dec 2014 · 7,265 accessesView PDF Cite
