Research ArticleOpen accessEvery word in the titleSimple 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 accessEvery word in the titleSimple 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 PDFCite
Research ArticleOpen accessEvery word in the titleDetermination of Minimal Duration Essential for Isolation of Humic Acids From Soils in Forest Restoration ProgrammesMohd Ramzan Nur Hanisah, Osumanu Haruna Ahmed, Kasim Susilawati et al.This study was conducted to investigate whether a simple and rapid method could be developed for extracting, fractionating and purifying soil HA in forest rehabilitation programmes. Humic acids from 10 g of soil were extracted with 100 mL of 0.10 M NaOH. Different extraction periods (4, 8, 12, 16, 20 and 24 h) were tested. Samples were centrifuged (16,211 G … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,173 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFault Detection and Isolation in Dynamic Systems using Statistical Local Approach and Hybrid Least Squares AlgorithmBelkacem Athamena, Zina Houhamdi, Mohammed MuhairatA fault detection and isolation (FDI) scheme for dynamic system proposed. This study deals with the design of discrete-time linear system using delta operator approach and the hybrid least squares (HLS) algorithm. A third residual generation based on statistical local approach and the derivative of the normalized residual on a small temporal window investigated. This new technique meets the desired … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 7,430 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Influence Of Isomerised Plant Oils With High Content Of Conjugated Dienes Of Linoleic Acids c9,t11 And t10,c12 On The Fat Reduction In The Carcass And Meat of LambB. Patkowska-Sokola, R. Bodkowski, W. Walisiewicz-Niedbalska, S. ZielinskiAn influence of isomerised poppy seed oil on lamb body fat and fat content in meat, and also fatty acids content was determined in the research. As a result of poppy seed oil isomerisation, the synthesis of conjugated dienes of linoleic acid of trans-10, cis-12 and cis-9, trans-11 configuration in amounts 34.3% and 32.2%, respectively, occurred. The enrichment of feed … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,225 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIsolation and Purification of Bacterial Strains from Treatment Plants for Effective and Efficient Bioconversion of Domestic Wastewater SludgeK. C.A. Jalal, Md. Z. Alam, Suleyman A. Muyibi, P. JamalForty six bacterial strains were isolated from nine different sources in four treatment plants namely Indah Water Konsortium (IWK) sewage treatment plant, International Islamic University Malaysia (IIUM) treatment plant-1,-2 and -3 to evaluate the bioconversion process in terms of efficient biodegradation and bioseparation. The bacterial strains isolated were found to be 52.2% (24 isolates) and 47.8% (22 isolates) in the … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 7,575 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIsolation and Mutagenesis of Streptokinase Producing BacteriaThaer Taleb Abed Abdelghani, Adinarayana Kunamneni, Poluri EllaiahOf 103 β-haemolytic Streptococci (with haemolytic activity) in total were isolated from different samples of blood and biomass from infected throat, 47 isolates exhibited streptokinase (SK) activity. T3, identified as a new variant of Streptococcus equisimilis, was found to be excellent SK producer in submerged fermentation and was selected for strain improvement studies.
