Research ArticleOpen accessIn the abstractPhysiological Response of Soybean (Glycine max) to Foliar Application of Methanol Under Different Soil MoisturesFarzad Paknejad, Mojtaba Mirakhori, Majid Jami Al-Ahmadi et al.Problem statement: Many cultivated area are situated in arid zone, where crop photosynthesis and productivity has limited by drought. Thus any treatment, such as methanol, that improve plant water relation and reduce stress impacts, could be benefit. Approach: In order to investigate effects of methanol application on some physiological properties of soybean under low water stress, a factorial experiment was … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Potassium and Calcium Hydroxide, Compost and Humic Acid from Sago (Metroxylon sagu) WasteC. P. Auldry, O. H. Ahmed, A.M. Nik Muhamad et al.Problem statement: Agriculture waste such as Sago Waste (SW) has a potential to cause pollution when the waste is discarded into rivers. In order to add value to SW, a study was conducted to produce potassium and calcium hydroxide, compost and Humic Acid (HA) from SW. Approach: The SW was air-dried and some grinded. The grinded SW was incinerated at … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,583 accessesView PDFCite
Research ArticleOpen accessIn the abstractCo-Digestion of Palm Oil Mill Effluent and Refined Glycerin Wash Water for Chemical Oxygen Demand Removal and Methane ProductionA. Sulaiman, M. R. Zakaria, M. A. Hassan et al.Problem statement: Refined Glycerin Wash Water (RGWW) from the oleochemical industry contains high Chemical Oxygen Demand (COD) and requires proper treatment before disposal. Unfortunately the wash water also contains high concentration of sodium chloride (NaCl) that could cause inhibition to the normal biological treatment process. However, there is feasibility of co-digesting the RGWW and Palm Oil Mill Effluent (POME) for … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,936 accessesView PDFCite
Research ArticleOpen accessIn the abstractArsenic Adsorption on Bauxite Mineral Using Batch Equilibrium TestFares Yahay Alshaebi, Wan Zuhairi Wan Yaacob, Abdul Rahim Samsudin, Esmail AlsabahiProblem statement: Study suggested a solution to remove arsenic contamination from contaminated water. Approach: Bauxite, which is a mineral, was proposed as natural remediation material used in this study. Bauxite was collected from Johor mining company in Teluk Ramunia, Johor Bharu, Malaysia. Batch equilibrium test was performed in accordance to different initial concentrations, shaking time and different initial pH values. … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 6,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuitability Evaluation of Groundwater for Irrigation, Drinking and Industrial PurposesM. A. Hakim, A. S. Juraimi, M. Begum et al.Problem statement: Groundwater is an important source of freshwater for agricultural, drinking and domestic uses in many regions of the world including Bangladesh. Demand of groundwater has been increasing day by day for irrigation by bringing more area under cultivation. As a drinking water the bottled water market currently has an average annual growth rate of 7.4% between 2002 and … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 8,644 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on Geomechanical Properties of Tropical Organic Soils and PeatBujang B.K. Huat, Afshin Asadi, Sina KazemianProblem statement: Organic soils and peat were believed to be geotechnically problematic due to their very high compressibility, very low shear strength and difficult accessibility. Although conventional soil mechanics theory could be applied to the soils, it was found that important anomalies existed which required special considerations. Correlations between geomechanical parameters for the soils were known to be important for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 10,172 accessesView PDFCite
Research ArticleOpen accessIn the abstractChemical and Physical Characteristics of Cocopeat-Based Media Mixtures and Their Effects on the Growth and Development of Celosia cristataYahya Awang, Anieza Shazmi Shaharom, Rosli B. Mohamad, Ahmad SelamatProblem statement: Cocopeat is considered as a good growing media component with acceptable pH, electrical conductivity and other chemical attributes but it has been recognized to have high water holding capacity which causes poor air-water relationship, leading to low aeration within the medium, thus affecting the oxygen diffusion to the roots. Incorporation of coarser materials into cocopeat could improve the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 19,001 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh Quality Komatsuna (Brassica rapa L. nothovar) Production by Using Silicate Minerals Treated Nutrient SolutionSheheli Islam, Kumagai Kazunori, Noriko Takeda, Katsumi IshikawaProblem statement: Good water quality not only produces good crop yield, but also maintains environmental quality and so with plant, animal and human health. Therefore, protecting the quality of water by using non chemical materials is an emerging issue to be solved. Bakuhan seki having additional negative charge were found to have the capacity of improving condition of water while … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,637 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Low-Temperature Technology of Producing Calcium Feed Phosphate with MicroelementsJózef HoffmannThe possibility of producing feed calcium phosphates in a way ensuring a low physical water content in the product was investigated in laboratory conditions. For this purpose the process use of a phosphoric acid solution with a higher (than in conventional methods) P2O5 content (53-63% by wt. P2O5) with CaO (molar fraction of 0.5-0.8) and CaCO3 in the phosphoric acid … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,739 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship Between Shear Strength and Soil Water Characteristic Curve of an Unsaturated Granitic Residual SoilThamer Ahmed Mohamed, Faisal Hj. Ali, S. Hashim, Bujang B.K. HuatShear strength parameters are crucial for stability analyses of slopes against slope failures and landslides. The three shear strength parameters that are required to define a failure envelope of an unsaturated soil are c’ (apparent cohesion), Φ’ (effective angle of friction) and Φb (shear strength change with change in matric suction). A soil-water characteristic curve (SWCC) that relates the water … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 7,350 accessesView PDFCite
