Research ArticleOpen accessIn the abstractPhylogeny and Molecular Study of Some Entomopathogenic Rhizobacteria Isolated from Two Regions in AlgeriaOulebsir-Mohandkaci Hakima, Benzina Farida, Khemili-Talbi Souad et al.The use of bacteria in the control of insect pests is a form of biological control whose practice is still not widespread. It is in this context that the present work falls. It concerns the isolation, characterization and identification of local bacterial strains for the purpose of their use in the control of certain pests. Indeed, 20 bacteria were isolated … …Current Research in Bioinformatics, Vol. 8, Issue 1 · 2 Mar 2020 · 7,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction and Characterization of Hydrocarbon Degrading Peroxidase from Rhizopus and Saccharomyces SpeciesFerdinand U. Paschaline, Onyeocha O. Ignatius, Ezeji E. Uchechukwu et al.The production, characterization and partial purification of hydrocarbon degrading peroxidase from di-culture of Rhizopus and Saccharomyces species was assessed. The fungi were isolated from hydrocarbon polluted soil and identified using standard microbiological and biochemical techniques. Fermentation was carried out for enzyme production and the extracellular extract was precipitated with 50% ammonium sulphate salts and further purified by gel filtrationusing sephadex … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 7 Dec 2019 · 7,398 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Soils Electrical Resistivity using Artificial Neural Network ApproachKpomonè Komla Apaloo-Bara, Adekunlé Akim Salami, Mawugno Koffi Kodjo et al.The knowledge of the ground electrical resistivity is essential to ensure the protection of electrical and telecommunications networks. However, the monitoring of its values is an expensive task which takes long time. Therefore, its prediction is important. This study investigates on predicting soil electrical resistivity using Artificial Neural Networks. Nine sites of our city (Lome, TOGO) were considered. After characterization … …American Journal of Applied Sciences, Vol. 16, Issue 2 · 13 Mar 2019 · 9,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Bitumen Addition on Sabkha Soil Shear Strength Characteristics under Dry and Soaked ConditionsFahad A. Alotaibi, Humoud Melfi AldaihaniHigh salt content in sabkha soils means they are significantly affected by changes in water content. Dissolution of salts within sabkha soil mass decreases their shear strength upon inundation with water, resulting from the destruction of cementation bonds between soil particles. Therefore, successful improvement for these soils must be based on reducing the dissolution of sabkha salts to minimize their … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 13 Nov 2018 · 7,388 accessesView PDFCite
EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractCHARACTERIZATION OF OIL PALM EMPTY FRUIT BUNCH AND RICE HUSK BIOCHARS AND THEIR POTENTIAL TO ADSORB ARSENIC AND CADMIUMNorazlina Abu Sari, Che Fauziah Ishak, Rosenani Abu BakarBiochar as a new soil amendment has a potential in controlling the fate of trace elements in the soil system. However, the production of biochar from different feedstocks and pyrolysis conditions resulted in variable biochar properties which have an influence on trace elements availability. The experimental works are focused on physical and chemical properties of biochars produced from Empty Fruit … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 13 Aug 2014 · 10,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and Characterization of Antibiotic-Producing Actinomycetes IsolatesMeera Kumari, Bat-Erdene Myagmarjav, Birendra Prasad, Madhusudan ChoudharyActinomycetes are a gram-positive, filamentous subgroup of bacteria most known for antibiotic production. In fact, most of the antibiotics available today have originated from actinomycetes, namely from the genus Streptomyces. Novel bacteria with antimicrobial activities have been discovered from bacterial screen studies for decades and there is still much more yet to be unearthed. One hundred seventy five strains of … …Current Research in Microbiology, Vol. 4, Issue 1 · 25 Jun 2013 · 15,437 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Overview on Studying 222Rn Exhalation Rates using Passive Technique Solid-State Nuclear Track DetectorsMohamed Abd-ElzaherProblem statement: Uranium is a radiotoxic element found in trace quantities in alomost all natural accurring materials like soil, rock. Radon an inert radioactive gas whose predecessor in uranium, is emitted from soil beneath the house and from building materials. Accurate knowledge of exhalation rate plays an important role in characterization of the radon source strength in some building materials … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 17 Aug 2012 · 8,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Flow Systems and Their Response to Climate Change: A Need for a Water-System View ApproachJoel J. Carrillo-Rivera, Antonio CardonaProblem statement: The interest in early hydrogeological studies was the aquifer unit, as it is the physical media that stores and permits groundwater transfers from the recharge zone to the discharge zone, making groundwater available to boreholes for water extraction. Approach: Recently, the aquifer concept has been complemented by the groundwater flow system theory, where groundwater may be defined by … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 7 Apr 2012 · 8,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensor Technologies for Precision Soil Nutrient Management and MonitoringA. Bah, S. K. Balasundram, M. H.A. HusniProblem statement: Growing concerns about the need to increase crop productivity without causing environmental injury have led to the deployment of site-specific strategies in soil nutrient management, where nutrients are applied in variable rates to fit local requirements. Variable rate application of nutrients is typically based on a rigorous sampling regime and time-consuming data analyses. The ability to monitor soil … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 25 Jan 2012 · 9,127 accessesView PDFCite
