Research ArticleOpen accessIn the abstractA Study of the Production Rules for Context Inference of Wetland Water Quality on Ubiquitous Sensor Network Middleware FrameworkSo-Young Im, Ryum-Duck OhProblem statement: With gradually increasing movement to live together with nature, artificial wetlands are increasing as well. And the wind of change blows at the rivers and streams, thereby increasing the need for management systems. Conclusion/Recommendations: Accordingly, this study aims to design production rules for wetland environment context inference and establish application system by using JESS and the rule-based system … …Journal of Computer Science, Vol. 8, Issue 3 · 13 Jan 2012 · 6,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractActive Faulting and Quaternary Landforms Deformation Related to the Nain FaultAbolghasem Gourabi, Mojtaba YamaniProblem statement: Landforms developed across terrain defining boundary the Nain fault have imprints of recent tectonic activity in the west region of Central Iran. Depositional landforms such as alluvial fans bear signatures of later phases of tectonic activity in the form of faulting of alluvial fan deposits and development of fault traces and scarps within 100 km long and a … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 2 Nov 2011 · 7,823 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Lead in Human Teeth by Hydride Generation Atomic Absorption SpectrometryHassan T. AbdulsahibProblem statement: The determination of lead in human teeth at concentration levels of μg/ml is proposed using Hydride Generation Atomic Absorption Spectrometry (HG-AAS). To do this, 2% (wv) lanthanum chloride solution was employed as matrix modifying reagent to increase sensitivity and remove matrix interferences. Approach: About 100 μL of sample and 100 μL of 3.0% (m/v) NaBH4 are simultaneously injected … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 31 Oct 2011 · 7,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Efficient Aggregation for Continuous Monitoring Applications of Wireless Sensor NetworkR. Rajkamal, P. Vanaja RanjanProblem statement: Continuous Monitoring of time critical phenomenon is one of the major streams of possible application in this arena. Sensing and Monitoring of such phenomenon involves in dealing with large amount of data correlated in spatial and temporal dimensions. Most applications of WSN, the nodes are hard to reach and it is impossible to replace their batteries so the … …Journal of Computer Science, Vol. 8, Issue 1 · 28 Oct 2011 · 7,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractCatch Composition of Tsetse Flies (Glossina: Glossinidae)K.E. Okoh, I.S. Ndams, E. Kogi, C.G. VajimeProblem statement: A study to determine the composition of tsetse flies species was conducted between January and December, 2007 in Kamuku National Park, Nigeria, using Biconical and Nitse traps. Tsetse flies were trapped along gallery forest in five streams for two trapping days and were collected daily. Approach: All tsetse flies caught were identified to species level, sexed, separated into … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 7,440 accessesView PDFCite
Research ArticleOpen accessIn the abstractComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Environmental Attitude among Pupil Teachers in Relation To Responsible Environmental Behavior: A Leap towards Sustainable DevelopmentSudeshna LahiriProblem statement: Recognizing the importance of ’Environmental Education’ to be introduced in every level of school education, agencies responsible for curriculum reforms and text books preparation in India have made the subject as an integral part. It is felt necessary to investigate whether the teachers, who are disseminating the knowledge, are equipped with environmental attitude and the behavior towards environment … …Journal of Social Sciences, Vol. 7, Issue 1 · 18 Dec 2010 · 8,877 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of an Insecticide Abamectin on Some Biochemical Characteristics of Tilapia Fish (Oreochromis Niloticus)Mohammed A. Al-KahtaniProblem statement: Presence of pesticide in streams and lakes is largely due to the runoff from agricultural fields. Pesticides are not highly selective but are generally toxic to many macrophytes, non-target organisms such as fish. Fish, generally accumulate contaminants from aquatic environments and have been largely used in food safety studies. Approach: The toxic effect of the insecticide abamectin on … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 9,594 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Mercury Mine Activities on Water Resources at Azzaba-North-East of AlgeriaFadila Alligui, Abdelhak BoutalebProblem statement: Mercury mineralization occurred in Azzaba (north-eastern Algeria) as a part of mercurial Numidian belt, consists of numerous of Hg deposits (Koudiat Sma, Mrasma, Guenicha, Fendek, Ismail and Ras Elma). These deposits are hosted in a variety of lithologies including sandstone, limestone, breccias and conglomerate. The ores occur as cinnabar deposits in Ypresian-Lutetian formations. Although the quantity and type … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,493 accessesView PDFCite
Research ArticleOpen accessIn the abstractAttributes of Domestic Water Sources in a Rapidly Urbanizing State Capital in a Developing EconomyA. E. OlajuyigbeProblem statement: The efficiency and effectiveness of domestic water sources are often gauged by availability, accessibility and adequacy. This study examined various variables that could be harnessed in measuring these parameters with respect to water supply in Ado-Ekiti, Nigeria. Approach: The purpose of this study is to investigate the various attributes of domestic water sources in Ado-Ekiti, Nigeria. Three residential … …Journal of Social Sciences, Vol. 6, Issue 2 · 30 Jun 2010 · 8,119 accessesView PDFCite
