Research ArticleOpen accessIn the abstractElectroosmotic Phenomena in Organic SoilsAfshin Asadi, Bujang B.K. Huat, M. M. Hassim et al.Organic soils or peat represent an accumulation of disintegrated plant remains which have been preserved under condition of incomplete aeration and high water content. In order to develop a fundamental understanding of electroosmotic phenomena in peat, initially microelectrophoresis studies were carried out to conceptualize the electrokinetic phenomena. Then electroosmosis experiments were conducted on rigid cube samples containing 0.0001 M NaCl-water … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhenanthrene Contaminated Soil Biotreatment Using Slurry Phase BioreactorM. Arbabi, M. Sadeghi, Ch. AnyakoraProblem Statement: Polycyclic Aromatic Hydrocarbons (PAHs) are suspected toxins that accumulate in soils and sediments due to their insolubility in water and lack of volatility. Slurry-phase biological treatment is one of the innovative technologies that involve the controlled treatment of excavated soil in a bioreactor. Due to highly soil contamination from petroleum compounds in crude oil extraction and also oil … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling of Oxygen Transfer Correlations for Stirred Tank Bioreactor Agitated with Atypical Helical Ribbon ImpellerMohd Shamzi Mohamed, Rosfarizan Mohamad, Ramakrishnan Nagasundara Ramanan et al.Problem Statement: Mixing filamentous fungi entails delicate balance between promoting high volumetric oxygen transfer coefficient (kLa) while keeping low hydrodynamic stresses in the microenvironment of cultures. This study examined the oxygen transfer capability of a prototype low shear helical impeller as a potential replacement for the standard Rushton turbine. Approach: The dependence of kLa upon specific power uptake, superficial gas … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,167 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 · 8,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimple and Rapid Method of Isolating Humic Acids from Tropical Peat Soils (Saprists)Shamsuddin Rosliza, Osumanu Haruna Ahmed, Kasim Susilawati et al.Problem Statement: The isolation (extraction, fractionation and purification) of humic acids (HA) from soils is laborious, time consuming and expensive. The extraction, fractionation and purification periods of these substances vary from 12 h-7 days. In order to facilitate production of HA at competitive cost, this study was conducted to investigate whether a simple and rapid procedure could be developed for … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 8,552 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecretary IgA Concentrations and plasma Cell Count Changes Associated with the Estrous Cycle in EwesMorteta H. AL-Medhtiy, A. B.Z. Zuki, M. M. Noordin, S. AgungpriyonoProblems statement: The level of uterine Secretory-IgA (S-IgA) and numbers of plasma cells was measured to observe the differences between two stages of estrous cycle (follicular and luteal phase) in the healthy cycling non pregnant ewes. Approach: Twelve ewes were used in this study and they were divided into two groups of 6 animals each according to the stages of … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,189 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurvival of Vibrio cholerae O139 in Association with Anabaena variabilis in Four Different MicrocosomsZannatul FerdousInvestigation was carried out to see the association of Vibrio cholerae O139 with Anabaena variabilis, in four different types of water. Conventional media were used to count culturable bacteria while epi fluorescence microscopy to count the viable but non culturable (VBNC) V. cholerae O139. It was found that the culturable form of V. cholerae O139 found 9 days in the … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 8,316 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiocontrol of Botrytis allii Munn the Causal Agent of Neck Rot, the Post Harvest Disease in Onion, by use of a New Iranian Isolate of StreptomycesM. Jorjandi, G.H. Shahidi Bonjar, A. Baghizadeh et al.Problem statement: Soil actinomycetes particularly Streptomyces spp. have showed antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. Onion neck rot or gray mold caused by Botrytis allii have imposed economic post harvest damages to onion bulbs and decreased its storage durability and market value. Approach: To investigate for … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractGastroprotective Effects of Melastoma malabathricum Aqueous Leaf Extract against Ethanol-Induced Gastric Ulcer Iin RatsFouad Hussain, Mahmood Ameen Abdulla, Suzita Mohd Noor et al.The gastro-protective effects of the aqueous leaf extract of Melastoma malabathricum was investigated against ethanol-induced gastric mucosal injuries in rats. There were four groups of adult sprague dawley rats, consisting of six rats per group. Macroscopically, oral administration of absolute ethanol to rats that had been pre-treated with only distilled water significantly produced extensive lesions of the gastric mucosa. Oral … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 7,774 accessesView PDFCite
