Research ArticleOpen accessIn the abstractDesorption of Exchangeable Cations at Adsorption of Lead Ions by Chernozem in the Presence of Attendant AnionsT. M. Minkina, D. L. Pinskii, S. S. Mandzhieva et al.The effect of Cl–, Ac‾ and NO3‾ anions on the adsorption of Pb cations by an ordinary chernozem and desorption of exchangeable cations in the soil-solution system has been assessed under model laboratory conditions. It has been shown that the attendant anions affect the shape of the adsorption isotherms, which are described by the Langmuir equation. The greatest influence on … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 20 Oct 2015 · 6,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeatures of Microelement Composition of Ordinary Chernozems of the Azov and Lower Don RegionsTatiana M. Minkina, Nikolay N. Miroshnichenko, Aleksandr I. Fateev et al.Ordinary chernozems in the Azov Plain have a low background content of mobile zinc compounds, a sufficient supply with copper and an increased content of lead compounds. This specificity of the regional microelement composition is due to the high carbonate content in the soil profiles, the natural enrichment of littoral geochemical landscapes and the effect of the significant sources of … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 3 · 27 Jul 2015 · 7,398 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormonal and Histopathological Alterations in Pituitary Glands and Reproductive Organs of Male and Female Mice Orally Inoculated with Pasteurella Multocida Type B: 2 and its LipopolysaccharidesFaez Firdaus Jesse Abdullah, Lawan Adamu, Abdulnasir Tijjani et al.Oral infections of mice as animal model with Pasteurella multocida type B: 2 and its lipopolysaccharides is liable to cause detrimental alterations in the pituitary glands, which results in disruption of reproductive hormonal levels as well as organ functions in the male and female animals; thereby impeding the fertility of at risk animal population. Therefore, this study was designed to … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 1 · 23 Dec 2014 · 7,559 accessesView PDFCite
Research ArticleOpen accessIn the abstractAN ENHANCED ROUTE FAILURE RECOVERY MODEL FOR MOBILE AD HOC NETWORKSP. R. Jasmine Jeni, A. Vimala Julie, A. Messiah BoseIn Mobile Ad Hoc Networks (MANET), change in topology of the network occurs due to the mobility factor of the nodes leading to the extension in size of the network. The extension of network size happens due to the entry of nodes into the network. As the topology changes, link failure between the nodes takes place due to several reasons … …Journal of Computer Science, Vol. 10, Issue 8 · 8 Apr 2014 · 6,739 accessesView PDFCite
Research ArticleOpen accessIn the abstractDETECTION OF FLOOD ATTACKS IN DTN USING RATE LIMITER TECHNIQUEC. Balamurugan, M. Viswanathan, T. Abhishek Kumar, G. S. RajFlood attacks means a network becomes so weighed down with packets, caused by the attackers. It prevents packets being sent/received between the nodes in the network. There are many methods adopted to prevent flood attacks in other networks, but none has been installed successfully for DTN’s. Disruption tolerant network is a network, developed in such a manner that intermittent communication … …Journal of Computer Science, Vol. 10, Issue 7 · 19 Feb 2014 · 6,986 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Annealing Temperature on Characteristics of Bismuth Doped Zinc Oxide FilmsSirirat Tubsungnoen Rattanachan, Phanuwat Krongarrom, Thipwan FangsuwannarakIn this study, Bismuth (Bi) doped ZnO thin films were deposited on quartz substrates by a sol-gel spin coating method and annealed at different annealing temperatures of 200, 300, 400, 500, 600 and 700°C, respectively. Structural and optical properties of nanocrystalline Bi-doped ZnO film on quartz were investigated by using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and UV-VIS spectrophotometer. … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 1 Oct 2013 · 7,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolymerase Chain Reaction Detection of Pasteurella multocida Type B: 2 in Mice Infected with Contaminated River WaterFaez Firdaus Jesse Abdullah, Mohammed Muqdad Khaleel, Lawan Adamu et al.Hemorrhagic septicemia is an acute, deadly disease of cattle and buffaloes associated with colossal economic loss in the livestock industry in the Asian regions particularly Malaysia. Therefore, this study was conducted to investigate on the Polymerase chain reaction detection of Pasteurella multocida type B: 2 in mice inoculated through different routes with river water contaminated with infected mice carcasses. Sixty … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 3 · 17 Sep 2013 · 7,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Melaleuca cajuputi as Heavy Metals Phytoremediator for Sewage Sludge Contaminated SoilShibli Nik Mohd, Nik Muhamad Majid, Noor Azhar Mohamed Shazili, Arifin AbduIn 2011, total marine capture landings in Peninsular Malaysia decreased by 3.9% which amounted to 1,373,105 tonnes as compared to 1,428,881 tonnes in 2010. The decline is connected to marine pollution which mainly comes from land based sources. Coastal forests play an important role affecting the marine ecosystem health and need to be conserved as a buffer to minimize pollution … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,470 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimultaneous Determination of Amlodipine and Atorvastatin in Caduet® Tablets Using HPLCMaha Abdalla AlnowaiserA simple, selective, sensitive and precise, simultaneous high performance liquid chromatographic analysis of tablets containing amlodipine and atorvastatin was described. Good chromatographic separation was achieved using a Perfectsilr Target ODS-3 (4.6 cm × 250 mm, 5 µm) and a mobile phase consisting of acetonitrile-phosphate buffer pH 4.5 (55:45, v/v) at a flow rate 1ML min-1. The ultraviolet detector was set … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Scale Modeling to Estimate Phosphorus and Sediment Load Reductions Using a Newly Developed Graphical User Interface for Soil and Water Assessment ToolAaron R. Mittelstet, Erin R. Daly, Daniel E. Storm et al.Streams throughout the North Canadian River watershed in northwest Oklahoma, USA have elevated levels of nutrients and sediment. Soil and Water Assessment Tool (SWAT) was used to identify areas that likely contributed disproportionate amounts of Phosphorus (P) and sediment to Lake Overholser, the receiving reservoir at the watershed outlet. These sites were then targeted by the Oklahoma Conservation Commission (OCC) … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 28 Dec 2012 · 6,473 accessesView PDFCite
