Research ArticleOpen accessIn the abstractHeavy Metals and Anion Levels in Some Samples of Vegetable Grown Within the Vicinity of Challawa Industrial Area, Kano State, NigeriaJ. C. Akan, F. I.A. Abdulrahman, V. O. Ogugbuaja, J. T. AyodeleProblem section: Effluents from the surrounding industries such as tannery and textile are used by vegetable farmers for the irrigation of their crops. These effluents may contain some toxic metals which bioaccumulate along the food chain. Moreover the uptake of such toxic metals by crops is governed by their availability and concentration in the soil. Therefore such crops may accumulate … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 9,270 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 abstractHard Coal Fly Ash and Silica-Effect of Fine Particulate Matter Deposits on Brassica chinensisChristian Ulrichs, Uwe Schmidt, Tanja Mucha-Pelzer et al.Problem statement: One focus in recent atmospheric pollution research is on fine Particle Matter (PM), especially as result of increasing traffic and anthropogenic activity in urban areas. Here, the impact on animal and human health has been in the center of many studies. Despite the fact that PM depositions can affect plants on the long term, there are only few … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,648 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Zeolite from Aluminium Etching By-Product: the Effect of Reaction Temperature on Crystallinity and Its CO2 Adsorption PropertyKanokorn Hussaro, Supaporn Douglas, Noppadon CheamsawatThe synthesis of zeolite from the by-product of aluminium etching process was investigated. The starting by-product reactant had high aluminium content, 92.17% wt. as Al2O3. Si and Na compositions were adjusted by the addition of sodium metasilicate, in the hydrogel process.The reaction time was fixed at 1 h., while the stirring speed was controlled at 200 rpm. and the temperature … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,524 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeismic Behavior of Vertical Shear Links made of Easy-Going SteelAmir Saedi Daryan, Hesam Bahrampoor, Masood Ziaei et al.Problem Statement: Since the time that steel was first used as a construction material, engineers have attempted to increase strength, reduce weight and produce more economical structures by using elegant member sections. However, the increase in steel strength and the decrease in cross section area are not always useful and in some cases it is necessary to reduce the strength … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,211 accessesView PDFCite
