Research ArticleOpen accessIn the abstractIntegrating Renewable and Nonrenewable Energies in Power Plant PlanningHabib H. Al-Ali, Yousef Saif, Ali Elkamel, Ali LohiProblem statement: Electricity can be generated from different type of technologies such as fossil and non-fossil power plants. Among these technologies, coal-fired power plants have been a major route for electricity generation. Recently, environmental constraints were imposed over the coal power plant operations in order to reduce their emissions. Besides, renewable energy power plants such as hydroelectric, wind, solar and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,811 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensity Equation of Cassava-Stalk Briquettes Under Moderate Die-PressurePatomsok WilaiponProblem statement: Agricultural residues seem to be the most promising energy resources for developing countries. However, the majority of them have low energy density. One of the favorable technologies for enhancing that property is briquetting. For the case of Phitsanulok, a province in Northern Thailand, cassava is one of the most important crops. Therefore, a large amount of cassava stalk … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Energy Storage in the Ground of a Greenhouse by the Polypropylene Capillary Heat ExchangerM. Lazâar, S. Koôli, M. Hazami et al.The problem of temperature inversion is one of solar origin principal problems about which the cultures under shelters complain. Indeed, for the winter period, the temperature under greenhouse is very low at night and it is rather high during the day in summer. Consequently, the heating of the greenhouses is essential. In this work, we studied the advisability of using … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,944 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Housing RenewalM. Sitar, K. KrajncFollowing the already proved models the sustainable planning culture is endangering several methods directed towards the needs of tenants in the existing post-war housing stock. The case-study of our project is the renewal of the multi stored building in the housing estate Metalna, Maribor/Tezno (1949). It is based on the sustainable renovation principle for the quality of sustainable housing in … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Approach to the Performance and Efficiency Power Analysis on Embedded Devices Using AsteriskAdauto Cavalcante Menezes, Toniclay Andrade Nogueira, Edward David Moreno Ordonez, Admilson de Ribamar Lima RibeiroVoice over IP (VoIP) communication will dominate the computing world for years to come. In order to perform VoIP communication, it is necessary to encode and decode the voice. This process consumes the main computational resources, as an example, it is possible to mention the processor and memory. The telecommunication industries provide equipment with high purchasing prices, which makes the … …Journal of Computer Science, Vol. 14, Issue 7 · 2 Aug 2018 · 8,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Feedlot Nutrients Runoff by Electrocoagulation ProcessArjun Thapa, Shafiqur Rahman, Md. Saidul BorhanNutrient runoff from Concentrated Animal Feeding Operations (CAFOs) may cause ground and surface water pollution. Scientists and researchers are continually searching for appropriate technologies to mitigate feedlot nutrient runoff pollution. In this study, suitability of electrocoagulation treatment process was examined under laboratory conditions to mitigate nutrient pollutants from the feedlot runoff. Feedlot runoff was treated with three different type of … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 9 Nov 2015 · 7,087 accessesView PDFCite
Case ReportOpen accessIn the abstractAn Economic and Environmental Evaluation of the Em-Ferro Plastic Sorting TechnologySeyedehfarzaneh Nojabaei, Omid Nematshahi, Matthew FranchettiRecycling has been continually practiced since the dawn of mankind; however, increasing production costs as well as environmental impacts of the conventional waste disposal methods have shed a light on the importance of recycling as a sustainable way to produce goods and services. Recycling has proven to be beneficial, economically and environmentally: It saves resources, prevents pollution, supports public health … …American Journal of Economics and Business Administration, Vol. 7, Issue 1 · 30 May 2015 · 6,982 accessesView PDFCite
