Research ArticleOpen accessIn the abstractIntegration of Electrical and Electromagnetic Investigation for Contaminated SiteAlberto Godio, Mario NaldiProblem statement: The environmental assessment of industrial areas is required to minimize the risk of soil and groundwater contamination. The survey of wide areas (e.g., some hectares) provides a high economical and complex logistical impact when random strategies of soil sampling are adopted. Recently, geophysical methods had been successfully adopted to drive the process of the spatial sampling of the … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,163 accessesView PDFCite
Research ArticleOpen accessIn the abstractWater Quality and Planktonic Communities in Al-Khadoud Spring, Al-Hassa, Saudi ArabiaAdel A. Fathi, Mohammed A. Al-KahtaniProblem statement: Al-Khadoud spring is one of the most important water resources in Al- Hassa Governorate, Saudi Arabia. However, much of its biotic information is still unknown. This study presented preliminary ecological information of this aquatic body. The aim of this research was to study the water characteristics and the planktonic organisms inhibiting Al-Khadoud spring and its irrigational channels for … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Characteristics of Leachate and Groundwater Pollution at Municipal Solid Waste Landfill of Ibb City, YemenEsmail Al Sabahi, S. Abdul Rahim, W.Y. Wan Zuhairi et al.Problem statement: Yemen one of the developing country suffering from water pollution. Landfill is one of the source of water pollution. There are several boreholes located close to Ibb landfill used for drinking water. A study of composition of landfill leachate and groundwater pollution was conducted at Ibb landfill, which is located at Al-Sahool area, north of Ibb City, Yemen. … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 9,186 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Groundwater and Surface Water Pollution at Mitm Area, Ibb City, YemenEsmail A. Sabahi, S. Abdul Rahim, W.Y. Wan Zuhairi et al.Groundwater and surface water samples were collected from Mitm area to study the possible impact of wastewater treatment percolation into the groundwater and surface water. The objective of the study is to assess the groundwater and surface water pollution due to wastewater treatment at Mitm area of Ibb city, in the Republic of Yemen. The concentrations of various physiochemical parameters … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractChemical and Physical Characteristics of Cocopeat-Based Media Mixtures and Their Effects on the Growth and Development of Celosia cristataYahya Awang, Anieza Shazmi Shaharom, Rosli B. Mohamad, Ahmad SelamatProblem statement: Cocopeat is considered as a good growing media component with acceptable pH, electrical conductivity and other chemical attributes but it has been recognized to have high water holding capacity which causes poor air-water relationship, leading to low aeration within the medium, thus affecting the oxygen diffusion to the roots. Incorporation of coarser materials into cocopeat could improve the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 19,001 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Response to the Application of Amendments in a Contaminated Soil with Trace ElementsA. Branzini, M. S. Zubillaga, M. M. ZubillagaProblem Statement: The anthropogenic activities can cause adverse effects in soils, increasing in some situations trace elements contents, impacting negatively both the microbial biomass and activity. Among the practices used for the recovery of soil quality we can find the application of organic amendments or the product of their composting. These can adsorb trace elements decreasing their availability and increasing … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractCalibration and Simultaneous Monitoring of Soil Water Content and Salinity with Capacitance and Four-electrode ProbesTadaomi Saito, Haruyuki Fujimaki, Mitsuhiro InoueNon-destructive monitoring of soil water content (W) and the electrical conductivity of the soil solution (ECw) has been desired for environmental evaluation and sustainable agriculture. Dielectric probes and four-electrode probes are widely used for the non-destructive determination of W and the soil bulk electrical conductivity (ECb), respectively. Since the output of dielectric probes is affected by soil salinity, the calibration … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,918 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Film thickness on the Electrical and Structural Properties of CdS: In Thin FilmsShadia J. Ikhmayies, Riyad N. Ahmad-BitarPolycrystalline CdS:In thin films were prepared by the Spray Pyrolysis (SP) technique on glass substrates at a substrate temperature Ts= 490°C. The effect of film thickness on the electrical and structural properties of the films was investigated through the analysis of the I-V plots, x-ray diffraction spectra (XRD) and the scanning electron microscope (SEM) images. The conductivity of the films … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 6,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesalination of Saline Sludges Using Ion-Exchange Column with ZeoliteA.E. Ghaly, M. VermaA flushing process followed by a zeolite based ion-exchange process were developed for the treatment of saline sludges from oil and gas exploration sites. The particle size distribution of sludge sample indicated the presence of very fine sand and clay. The electrical conductivity of the sludge was 42.2 dS m-1 indicating very saline sludge and the Cation Exchange Capacity (CEC) … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,062 accessesView PDFCite
