Research ArticleOpen accessIn the abstractEffect of Enhancing Urea-Humic Acid Mixture with Refined Acid Sulphate SoilMohd Taufik Mohd Yusuff, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Acid Sulphate Soil (ASS) is a problem soil partly because of its high acidity. This low pH could be exploited to reduce ammonia loss from urea by reducing soil microsite pH. The use Humic Acid (HA) to control ammonia loss from urea has been reported but the cost of this material is high. This laboratory study compared the … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,277 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCytoprotective Effect of UlGen, a Polyherbal Formulation against Physical and Chemical Factor Induced Gastric Ulcers in Wister Albino RatsT. S. Muralidhar, Anna Balaji, Chinmay Bandopadhyay, S. L. ShanthaProblem statement: UlGen, a Polyherbal formulation, was investigated for its possible Ulcero-protective activity in ulcerogen and Cold-restraint stress induced Wister rats (Rattus rattus). Oral administration of UlGen, at a dose of 800 mg kg-1 significantly protected the onset of cold-resistance stress induced ulcerations. Approach: It significantly inhibited gastric ulceration induced by alcohol and aspirin. Control group: Alcohol 80% induced ulcer … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 8,180 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSimple Method of Purifying Humic Acids Isolated from Tropical Hemists (Peat Soil)Susilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohd Khanif YusopThe objectives of this study were: To investigate whether a purification period of HA isolated from Hemists peat soils could be reduced and to investigate whether distilled water could be used to purify HA isolated from Hemists peat soils. Standard procedures were used to extract and fractionate HA in a Hemists peat soil. The isolated HA was purified by suspending … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,151 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of the Detoxification on the Shrinkage Temperature and pH of Chromium Leather Waste, Another Promising Way for the Tannery PollutionA. Malek, M. HachemiThe leather tannery industry produces a significant amount of solid chromium waste. Environmental concerns and escalating landfill costs are becoming increasingly serious problems to the leather industry and alternative disposal methods are needed. This research describes the possibility of decrease of the shrinkage temperature and to increase the pH value of leather waste by detoxification treatment with use of tartrate … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,114 accessesView PDF Cite

Research ArticleOpen accessIn the abstractConsumer's Acceptability Estimation of Cold Preserved Malaysian Freshwater PatinA. S. Mokhtar, K. A. Abbas, S. M. Sapuan, M. M.H. AhmadThe study presents an attempt to correlate the consumer acceptability of Malaysian Patin fish with the storage time and temperature. A batch of typical fresh fishes was cut into regular slices (samples), which were wrapped and distributed evenly to four cold stores by 0, 3, 5 and 10°C storage temperature for a period of 28 days. During the course of … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,180 accessesView PDF Cite
