Research ArticleOpen accessIn the abstractComparison of Selected Soil Chemical Properties of Two Different Mangrove Forests in SarawakEmpi Rambok, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Despite few studies of forest health and environmental conditions of mangrove forest in Sarawak, the data was not sufficient to facilitate baseline data and direct comparison of mangrove forest health obtained for different location of mangrove forest in Sarawak. On this regard, determination of contemporary mangrove soil condition was essential to addressing mangrove forest for forest health, carbon … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 9,648 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption Study of Several Hydrophobic Organic Contaminants on an Aquifer MaterialBarbara Ruffino, Mariachiara ZanettiProblem statement: Aim of the present research was to determine coefficient of partition KD between soil and groundwater for five hydrophobic organic pollutants (benzene, chlorobenzene, trichloroethylene-TCE, perchloroethylene-PCE and toluene) in an Italian aquifer material characterized by a low organic carbon content (fOC = 0.00262) by means of laboratory batch tests. Initial aqueous concentrations (quite different among the five compounds) were … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study on Potentiality of Carbon Storage and CO2 Uptake in the Biomass and Soil of Coppice StandA. Khademi, S. Babaei, A. MatajiProblem statement: Enhancing carbon storage in terrestrial ecosystems, especially in the forests, is a key factor in maintaining the atmosphere's carbon balance. With regard to the importance of forest in carbon sequestration, this study attempted to investigate the carbon storage potential and CO2 uptake in oak coppice stand. Approach: After combining slope, aspect and hypsometric maps, the number of land … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractMAM-An Aquivalence-based Dynamic Mass Balance Model for the Fate of Non-Volatile Organic Chemicals in the Agricultural EnvironmentMohammad A. Batiha, Abdul Amir H. Kadhum, Abu Bakar Mohamad et al.A Multimedia Agricultural Model (MAM) for predicting the fate and transport of Non-Volatile Organic Chemicals (NVOCs) in the agricultural environment was presented. It is an expanded and modified version of the three compartmental model introduced by Batiha and co-authors in 2007, which is an aquivalence-based level IV. MAM considered five environmental compartments to include the air, water, soil, sediment and … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 8,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Fate of Non-Volatile Organic Chemicals in The Agricultural EnvironmentMohammad A. Batiha, Abdul Amir H. Kadhum, Zahedi Fisal et al.Multimedia dynamic model of the fate of non-volatile organic chemicals (NVOC) in the agricultural environment is described. The modeled environment, consisting of up to three major surfaces environmental compartments, includes air, agricultural soil, and surface water. This model is based on the aquivalence approach suggested by Mackay and co-workers in 1989. As the movement of chemicals in the environment is … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Gas Velocity and Temperature on Nitric Oxide Conversion in Simulated Catalytic ConverterSathaporn ChuepengProblem statement: Gaseous emissions from gasoline engine such as carbon monoxide, unburned hydrocarbon and nitrogen oxides were usually reduced in three-way catalytic converter simultaneously around theoretical fuel and air combustion. Engine speed and load and other parameters were varied over a wide range of operating conditions, resulting in different exhaust gas composition and condition intake into catalytic converter. This work … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 27 Jun 2012 · 7,304 accessesView PDFCite
