Research ArticleOpen accessIn the abstractPhotovoltaic Technology of Electricity Generation for Desert CampingShafiqur Rehman, Ali A. Shash, Omar S. Baghabra Al-AmoudiThis study presents a case study on the utilization of global solar radiation data on horizontal surface to perform economical feasibility of using Photovoltaic (PV) panels with battery backup to meet a small load for a camping site in Saudi Arabia. The analysis considers three scenarios with daily average energy demands of: (i) full load, (ii) 75% load and (iii) … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,929 accessesView PDFCite
Research ArticleOpen accessIn the abstractOrganizations and Activities of a New Leading Farmer Extension Model in TurkeyGürel AydinWith this study, the organization and the activities of four leading farmer association established in Thrace Region of Turkey in 1986, in the center of Tekirdag and in Muratli, Corlu and Malkara districts of Tekirdag, were discussed as the result of the common studies between Turkish Agricultural Chamber Union (TZOB) and German agriculture unit (Deutsche Landwirtschafts-Gesellschaft, DLG), German Agricultural Technical … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Transcript Labeling Techniques and Development of a Membrane-based Parallel Gene Expression AssayMark A. Fisher, Bonnie B. Plikaytis, Thomas M. ShinnickAn inexpensive alternative to micro arrays was developed to examine the expression of small sets of genes in parallel and used to compare direct and indirect transcript labeling methods. Psoralen-biotin direct labeling was ~10-fold less sensitive than reverse transcriptase-biotin-dUTP labeling, but the enzymatic method generated higher levels of background noise in miniarray hybridizations. The reproducibility of hybridization intensities was the … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,875 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Adaptive Modulation Scaling Scheme for Quality of Services Ensurance in Wireless Sensor NetwoksYong Yuan, Zongkai Yang, Jianhua HeEnergy consumption has been a key concern of data gathering in wireless sensor networks. Previous research works show that modulation scaling is an efficient technique to reduce energy consumption. However, such technique will also impact on both packet delivery latency and packet loss, therefore, may result in adverse effects on the qualities of applications. In this study, the problem of … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,786 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Fractional Hold Devices Versus Positive Realness of Discrete Transfer FunctionsM. de la Sen, A. Bilbao- GuillernaThe appropriate use of fractional order holds (β-FROH) of correcting gains βε[-1,1] as an alternative to the classical zero and first order -holds (ZOH, FOH) is discussed related to the positive realness of the associate discrete transfer functions obtained from a given continuous transfer function. It is proved that the minimum direct input-output gain (i.e. the quotient of the leading … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,194 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistribution Network Planning and Design Using Branch and Bound MethodsJalal AbdallahThis study presents implementation of the bound and branch methods as an optimization mathematical device for distribution network planning. A development technology concentrates on minimizing the total costs and provides extended opportunities for improvement of network operation, from the initial planning stage. The study illustrate the mathematical and the algorithm of the branch and bound method with an example to … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,047 accessesView PDFCite
Research ArticleOpen accessIn the abstractED-XRF Analysis of Total Suspended Particulates from Enamelware Manufacturing IndustryJ. A. Sonibare, F. A. Akeredolu, O. Osibanjo, I. LatinwoConcentration and elemental composition of the total suspended particulates (TSP) emitted due to manufacturing activities of an enamelware industry in Lagos, Nigeria were investigated. Gravimetric method was used in mass concentration determination and an energy dispersive x-ray fluorescence (ED-XRF) analyzer was employed in the multi-elemental analysis. The Federal Ministry of Environment (FMENV, Nigeria's environment regulating body) set limit of 250 … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,687 accessesView PDFCite

This sand contains … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,340 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Polyelectrolyte in Turbidity Removal from Surface WaterA. H. Mahvi, M. RazaviOne of the most important treatment processes in surface water treatment plants is coagulation. Surface waters such as rivers and lakes contain suspended particles and turbidity. With the aid of coagulants, and by flocculation process, followed by sedimentation and filtration, these impurities can be removed from raw waters these days, besides conventional chemicals such as Alum and Ferric chloride, polymers … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 8,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractTeawaste as An Adsorbent for Heavy Metal Removal from Industrial WastewatersAmir Hossein Mahvi, Dariush Naghipour, Forugh Vaezi, Shahrokh NazmaraWater used in industries creates a wastewater that has a potential hazard for our environment because of introducing various contaminants such as heavy metals into soil and water resources. In this study, removal of cadmium, lead and nickel from industrial wastewaters has been investigated by using teawaste as a natural adsorbent. The research is a bench scale experimental type and … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 9,167 accessesView PDFCite
