Research ArticleOpen accessIn the abstractInfluence of Geosta Addition on Cement-stabilised Chicoco Mud of the Niger DeltaOlujide OmotoshoChicoco is a very soft and extremely compressible organic marine mud found extensively and to considerable depths within the saline tidal flat or mangrove swamp of the Niger delta in southern Nigeria. Natural chicoco is highly undesirable, barely able to support a human of average weight but air-dried chicoco has been used successfully by the indigeneous people for shore protection, … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,587 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInvestigating the Effects of Landfill in Azad-Shahr City on the Physicochemical Properties of GroundwaterSara Abdollahi, Safieh Javadinejad, Kaveh Ostad-Ali-Askari, Vijay P. SinghLocations near landfills have a lot of potential for contamination of groundwater, because there is a high potential for contamination with emulsion in these areas. In this study, the quality of physic chemical and carbon-organic materials (TOC) of water wells around landfill of Azad-Shahr city was investigated. To accomplish this purpose, sampling of water from seven deep wells around the … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 3 Jun 2019 · 7,931 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Use of Nano Silica for Improving Mechanical Properties of Hardened Cement PasteIntisar Kuli, Taher M. Abu-Lebdeh, Elham H. Fini, Sameer A. HamoushThe influence of adding Nano particles of silicon dioxide (SiO2) on cement pastes was studied for both water and vacuum curing methods. Specimens made up of different percentage of Nano Silica were tested at different ages ranging from 3-56 days. The effect of (5-20 nm) Nano-Silica on the strength development of Nano-cement was determined using Material Tests System (MTS). The … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 9,087 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDifferent Sorption Approaches and Leachate Fluxes Affecting on Mn2+ Transport through Lateritic AquiferSrilert Chotpantarat, Chakkaphan SutthiratProblem statement: Contamination of the underlying aquifer beneath a mining area is usually of great concern even when a prevention plan has been implemented. Approach: To assess the potential risk of heavy metal contamination, the simulation of heavy metal transport was carried out with different leachate fluxes and sorption parameters derived from equilibrium models with linear and Langmuir isotherms and … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 6,150 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSugarcane Response to Water-Deficit Stress during Early Growth on Organic and Sand SoilsDuli Zhao, Barry Glaz, Jack C. ComstockProblem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 10,263 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Different Ages of a Rehabilitated Forest on Selected Physico-chemical PropertiesRajeswari A.P. Murugayah, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: This research was important because of still lack of information about rehabilitated tropical forest age effect on infiltration rate. The objectives of this study were to determine the influence of age of forest on soil water infiltration rate and to evaluate the influence of forest age on the relationship between water infiltration rate, soil organic matter and soil … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,108 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordStructural and Substrate Interaction Properties of Alkaline Phosphatase from Paenibacillus sp. PSB04: In-Silico AnalysisHerman Umbau Lindang, Cahyo BudimanA Phosphate-Solubilising Bacterium (PSB) of Paenibacillus sp. PSB04 was previously isolated from the Sabah tropical rainforest in Malaysia. Interestingly, the genome sequence of the PSB04 strain harbored an Alkaline Phosphatase (AP) (EC 3.1.3.1) gene and was hypothesized to have unique structural characteristics. Therefore, this study aims to determine the AP three-Dimensional (3D) model and catalytic mechanism from Paenibacillus sp. PSB04 … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 16 Jul 2022 · 5,914 accessesView PDFCite
