Research ArticleOpen accessIn the abstractNumerical Investigation Into The Behavior of Circular Pad Shallow Foundations Supported By Geogrid Reinforced SandS. M. Marandi, M. H. Bagheripour, R. Rahgozar, A. R. GhirianThis study seeks to widen the pool of knowledge on the use and characteristics of geosynthetics, specifically in the area of circular foundations supported by geosynthetic reinforced sand. The main objective of the work was to increase the awareness of circular foundation systems and thus increase the accuracy of current laboratory methods. Also, compare the results with that of previous … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Performance of EPS Footing for Lightweight Farm Structure on Peat SoilMohammad Abdullah, Bujang B.K. Huat, Rezuwan Kamaruddin et al.The objective of this research project was to find a potential replacement for the conventional pile foundation principally for peat soil. It is fundamentally meant for lightweight and impermanent agricultural farm structures. Preceding the design and development of the foundation the physical characteristics of the in-situ peat such as; peat depth, soil consolidation, soil compressibility, water table, liquid limit, soil … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Levan by Bacillus licheniformis for Use as a Soil Sealant in Earthen Manure Storage StructuresAbdel E. Ghaly, F. Arab, N.S. Mahmoud, J. HigginsManure application is not permitted on frozen land in Canada and therefore, manure management and storage are the primary issues facing the agri-food industry. Low-cost, effective and environmentally safe earthen manure storage (EMS) facilities will lower costs and help make the livestock industry more competitive and efficient. The goal of this study was to develop a biological sealing technology for … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,974 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Environmental and Health Impacts of High Land Application of Cheese WheyA. E. Ghaly, N.S. Mahmoud, D.G. Rushton, F. ArabA laboratory scale experiment was carried out to study the transformation and transport of nitrogenous compounds in soils receiving high application rates of cheese whey (twice the nitrogen requirement for crops). The experimental apparatus consists of 36 soil columns constructed of 20 cm inside diameter PVC pipes. Three types of soil (sandy loam, loam and sandy clay loam) and three … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 8,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modelling of Pollutants’ Dispersion in Soil I. Case Study of Copper DispersionV. Viman, L. M. Cozmuta, A. M. Cozmuta et al.The study presents a mathematical modelling of copper dispersion in soil. The samples have been collected from the same points of the sampling network, from surface and depth in 2001 and only to surface in 2002 and analyzed using the ICP-AES method. The extrapolation of the experimental results led to the dispersion curves of the copper concentrations both at surface … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,477 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecific Features of the Accumulation and Distribution of Heavy Metals in Soils of the Floodplain and Deltaic Landscapes of the Don RiverTatiana M. Minkina, Dina G. Nevidomskaya, Yuriy A. Fedorov et al.The purpose of this work was to study specific features of the accumulation and distribution of the total content and mobile forms of Heavy Metals (HM) in soils of the estuarine ecosystems of the floodplain and deltaic landscapes of the Don River. The results allowed us to detect regional specific features in the formation of HM compounds in floodplain soils … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 19 Nov 2015 · 6,586 accessesView PDFCite
Research ArticleOpen accessIn the abstractSELECTIVE ISOLATION OF A GRAM NEGATIVE CARBAMATE PESTICIDE DEGRADING BACTERIUM FROM BRINJAL CULTIVATED SOILDilara Islam Sharif, Mithun MollickA bacterial species having the ability to grow in the presence of carbosulfan pesticide “Marshall” was isolated from Solanum melongena (brinjal) cultivated soil in Khulna region, Bangladeh, having a history of pesticide usage. The strain was morphologically and biochemically identified to belong to the genera Pseudomonas. A comparative study of growth of this strain with other isolated bacteria showed its … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 24 Sep 2013 · 7,448 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Thermostable α-Amylase Producing Natural Variant of Bacillus spp. Isolated From Soil in IranIraj Rasooli, Shakiba D. A. Astaneh, Hojjat Borna, Kamal A. BarchiniThermophilic processes appear more stable, rapid and less expensive and facilitate reactant activity and product recovery. Amylases have a quarter of the world enzyme market and thermostable a-amylases possess extensive commercial applications. Since little work has been done on strain isolation, growth and enzyme yield optimization, the level of thermophilic enzyme production remains relatively low. Therefore, large scale exploitation of … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,902 accessesView PDFCite
Research ArticleOpen accessIn the abstractStable Nitrogen Isotopic Changes in Winter Wheat (Triticum aestivum L.) Induced by its Growth TemperatureZhou Feng Wang, Wei Guo Liu, Rui Juan HaoThe nitrogen dynamics of plants can be quantified using the variation in their δ15N level. This reveals details of plant physiological characteristics and the relationship between plants and their growth conditions. To better understand plant nitrogen dynamics and the effects of external temperature changes on their nitrogen isotopic composition, we investigated the δ15N characteristics in Triticum aestivum and its mother … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 1 · 21 Mar 2017 · 8,119 accessesView PDFCite
