Research ArticleOpen accessIn the abstractGOLD MINING IN IGUN-IJESHA, SOUTHWEST NIGERIA: IMPACTS AND IMPLICATIONS FOR WATER QUALITYO. O. Ayantobo, J. A. Awomeso, G. O. Oluwasanya et al.This study was carried out in Igun-Ijesha, Osun State, Nigeria to determine the likely hotspots of water contamination for future treatment trials. Water quality analyses were based on physico-chemical and heavy metal parameters of surface and ground water collected from the study community. A total of thirty-eight water samples were collected between September 2012 and February 2013 and analyzed using … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 8 May 2014 · 9,137 accessesView PDFCite
Research ArticleOpen accessIn the abstractINDUCES OF ANTIOXIDANT COMPOUNDS AND SALT TOLERANCE IN WHEAT PLANT, IRRIGATED WITH SEAWATER AS RESPONSE TO APPLICATION OF MICROALGAE SPRAYHanaa H. Abd El Baky, M. M. Hussein, Gamal S. El-BarotyWheat plants (Triticum aestivum L., cv. Giza 168) irrigated with either 10 or 20% of Seawater (SW) were treated with aqueous extracts of green microalgae Scenedesmus obliquus and blue green algae Spirulina platensis (AESO and AESP 20 g (dry weight)/L) in order to increase wheat salt tolerance. Treated plants showed higher ability to tolerate salt stress (10 or 20% SW) … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 7 Jan 2014 · 7,596 accessesView PDFCite
Research ArticleOpen accessIn the abstractDrying Poultry Manure for Pollution Potential Reduction and Production of Organic FertilizerA. E. Ghaly, M. AlhattabDisposal and storage of raw poultry manure has become an environmental problem because of the associated air, water and soil pollution. Poultry manure begins to decompose immediately after excretion giving off ammonia which, in high concentrations, can have adverse effects on the health and productivity of birds as well as the health of the farm workers. Application to land is … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 13 Mar 2013 · 9,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeciation of Arsenic Across Water-Sediment Interface of Falgu RiverRajeeva Ranjan, Rekha Rani, Ashay Bavishi et al.Two predominant species of arsenic compounds, As(III) and As(V), are found in soils and natural water and they have been classified as carcinogens. The focus of the present study was to examine the speciation of Arsenic (As) across the water-sediment interface at the confluence of drainage for Gaya city and the Falgu River. Gas Chromatography (GC) coupled to Inductively Coupled … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 31 Dec 2012 · 6,876 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Complete Micro Nutrient Fertilizer Application on Soybean Yield and Yield ComponentsFarimah Ghannadi Behrouzi, Sardar Germchi, Mehrdad YarniaIn last decades, sever population growth cause to enormous problems in developing countries. One of the effective factors in improving of quantity and quality of agricultural products is optimal application of chemical fertilizers. Hence, any research in this field can be an effective step to decrease production costs and increase productivity. In order to evaluation effects of complete micro nutrient … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 5 Oct 2012 · 8,132 accessesView PDFCite
Research ArticleOpen accessIn the abstractRectangular Storm Sewer Design Under Equal Sediment MobilityJaber AlmedeijRectangular storm sewers are conduits delivering water to outfall locations and have sizes that are typically larger than standard pipes, by which they become subject to more sediment deposits during operation and thus require higher flow strengths to maintain the bed clean. This study suggests a design procedure of self-cleansing rectangular sewers based on maintaining a lower limit of Shields … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 19 Jun 2012 · 7,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractDietary β-glucan Leads to Increased TNF-α Production in the LungRadiah C. Minor, Melody L. Robinson-Wright, Morika Williams, Steven L. HurleyProblem statement: Beta (β)-glucan is notable for its ability to stimulate the immune system and as such β-glucan and products containing β-glucan are used as dietary supplements for livestock and companion animals. β-glucan has been shown to activate macrophages and neutrophils and modulate the production of certain cytokines, including the pro-inflammatory cytokine, Tumor Necrosis Factor Alpha (TNF-α). Because TNF-α is … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 2 · 11 Jun 2012 · 7,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractResidual Chromium in Leather by Instrumental Neutron Activation AnalysisS. Okoh, I. O. Okunade, D. J. Adeyemo et al.Problem statement: Most tanning processes employ the use of chromium sulphate. For chromium tanned leather, finished products may contain high amount of residual chromium. This may pose some health hazards, since chromium is known to be toxic at elevated concentration. This justifies the need for the study. Approach: Various samples of leather were collected from a tannery, a leather crafts … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 17 Jan 2012 · 7,504 accessesView PDFCite
