Approach: To investigate the effects of the submerged state fermentation parameters; concentrations of carbon g L-1; (10, 45 and 80), glucose, nitrogen g L-1; … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 10,086 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing the Urea-N Use Efficiency in Maize (Zea mays) Cultivation on Acid Soils using Urea Amended with Zeolite and TSPOsumanu Haruna Ahmed, Aminuddin Hussin, Husni Mohd Hanif Ahmad et al.Problem Statement: Ammonia loss significantly reduces urea-N use efficiency in crop production. Efforts to reduce ammonia loss are laboratory oriented, as such limited in reflecting actual field conditions. This paper reports the effects of urea amended with triple superphosphate (TSP) and zeolite (Clinoptilolite) on soil pH, soil nitrate, soil exchangeable ammonium, dry matter production, N uptake, fresh cob production and … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 8,878 accessesView PDFCite
Research ArticleOpen accessIn the abstractBacterial Contamination and Resistance to Commonly Used Antimicrobials of Healthcare Workers' Mobile Phones in Teaching Hospitals, Kerman, IranGholamreza Sepehri, Nooshin Talebizadeh, Ali Mirzazadeh et al.Problem Statement: The contamination rates of Health Care Worker's (HCW) mobile phones and resistance to commonly used antimicrobials were evaluated in three teaching hospitals in Kerman, Iran. So, we examined 150 randomly selected HCWs in three teaching hospitals in Kerman, Iran, 2007. For each HCW a sterile swab moistened with sterile water was rotated over the surface of both sides … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,777 accessesView PDFCite
Research ArticleOpen accessIn the abstractReview on Landfill Leachate TreatmentsAbdulhussain A. Abbas, Guo Jingsong, Liu Zhi Ping et al.Problem Statement: Sanitary landfilling is the most common way to eliminate solid urban wastes. An important problem associated to landfills is the production of leachates. This study is a review of landfill leachate treatments. Approach: The advantages and disadvantages of the various existing leachate treatments discussed under the items: (i) Leachate channeling (combined treatment with domestic sewage, recycling) (ii) Biological … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 13,764 accessesView PDFCite
Research ArticleOpen accessIn the abstractPneumatic and Hydraulic Systems in Coal Fluidized Bed CombustorZ. O. Opafunso, I. I. Ozigis, I. A. AdetundeProblem statement: This study designed the pneumatic and hydraulic systems in coal fluidized bed combustor. These are fluidization of silica sand bed material, Air distributor, centrifugal fan, electric motor power drive and surface heat exchanger. Approach: The effects of increased gas velocity on silica sand and the resultant drag force formed the basic equations in fluidization. Air distributor was introduced … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Al3Fe5O12 Cubic Structure by Extremely Low Sintering Temperature of Sol Gel TechniqueNoorhana Yahya, Ramadan A.H. Masoud, Hanita Daud et al.Problem statement: Fabrication of nano materials particularly nano inductors at low sintering temperature remains a challenge. This study was carried out as our initial response to obtain a nano-size inductors, which is aluminium iron garnet using low sintering temperature. Approach: The aluminum iron garnet (Al3Fe5O12) nano crystals were prepared by sol-gel technique. The starting solution is a mixture of iron … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,570 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel Metal Accumulator and Protease Secretor Microbes from East Calcutta WetlandSanhita Chowdhury, Madhusmita Mishra, V.K. Adarsh et al.Nine bacterial isolates were screened from different sites of East Calcutta Wetland, an ecosystem located at the eastern fringes of Calcutta. Other than being a biodiversity rich area, the important feature of this system is that it is a natural sewage treatment plant for the city of Calcutta. In addition to daily sewage including solid and soluble wastes, a considerable … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 8,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving a PCR-Based Method for Identification of Ralstonia solanacearum in Natural Sources of West MalaysiaReza Khakvar, Kamaruzaman Sijam, Wong Mui Yun et al.Ralstonia solanacearum, a soil-borne plant pathogen, causes lethal wilting disease of more than 200 plants worldwide. This very wide host range covers both monocots and dicots, extending from annual plants to trees and shrubs. Although generally it’s considered as a plant pathogen, R. solanacearum behaves primarily as a saprophytic bacterium able to survive for long periods of time in various … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 2 · 30 Jun 2008 · 9,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of Barley for the Purification of Aquaculture Wastewater in a Hydroponics SystemA.M. Snow, A.E. GhalyBarley was examined for its ability to remove nutrients from aquaculture wastewater. The effects of seed sterilization using ethanol and bleach and seed density on germination and plant growth were investigated. Surface sterilization of barley seeds had a negative impact on germination. Increasing the ethanol concentration and/or the bleach concentration reduced the germination percentage. Barley seeds were first germinated in … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 7,489 accessesView PDFCite
