Research ArticleOpen accessIn the abstractIdentification of Nocardiopsis dassonvillei in a Blood Sample from a ChildFlavio Lejbkowicz, Raya Kudinsky, Luisa Samet et al.Nocardiopsis dassonvillei is an environmental aerobic actinomycete producing a funguslike mycelium and aerial hyphae. Here we report the first Nocardiopsis dassonvillei isolated from a blood sample from a 3-year-old child hospitalized with fever, respiratory difficulty and cough. To the best of our knowledge this is the first time this organism has been detected in the BacT/Alert system. This Nocardiopsis was … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 7,280 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethyltert-butyl Ether (MTBE) Degradation by a Microbial ConsortiumS. B. Mortazavi, A. Nikpey, A. Rezaee et al.Methyl tert-butyl ether (MTBE) is added to reformulated gasoline to meet the 1990 Clean Air Act directives. Widespread use of MTBE in gasoline has resulted in groundwater contamination. Because of its undesirable effects on drinking water and ecologically harmful effects, MTBE removal has become a public health and environmental concern. In this study, we have isolated a mixed bacterial culture … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,994 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntibacterial Effect of Untreated and Treated (Decolorized) Dyes by Agricultural WastesSibel Kahraman, Pelin YalcinToxicity (antibacterial effect) of untreated and treated (decolorized) dyes on a soil bacterium, Pseudomonas aeruginosa was determined. Low cost and easily available two agricultural residues (cotton stalk and apricot seed) as biosorbents were used to remove Astrazone Black and Astrazone Yellow from aqueous solution. The removal of these dyes with agricultural wastes reduced the toxic effect on P. aeruginosa. This … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,260 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysics Models of Pronuclear Movements in EggsKang Cheng, Changhua ZouBased on published experimental data, Newton's laws, and Coulomb's law, we investigate natural and normal pronuclear movements in wild types of eggs and develop physics models to fit the experimental data quantitatively. The difference between our modeling calculated results and the experimental data is less than 20%. Our models explain why and how pronuclei move in even or in variant … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,743 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of a New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part II: Optimization of the System for Escherichia coliEric Carnes, Ebtisam WilkinsThe optimization of a flow-through immunoassay system was conducted to achieve rapid detection of low concentrations of E. coli bacteria. The system includes a new immunosensor that uses newly developed, disposable immunofiltration membranes to yield a system that is sensitive as well as simple. Comparison of the performance of this system with conventional immunoassays demonstrated a significantly shorter time for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractRAM 1.0 Software for Gaussian-Plume Multiple Source Air Quality SimulationLiren Yu, Paulo I.F. de AlmeidaThis study presents a developed software in environmental engineering, namely RAM 1.0 (RAM: Regulatory Air Model), adopted completely Graphical User Interface (GUI) technique, for operating in various Windows-based microcomputers. RAM 1.0 software consists of the improved RAM Model and RAM Algorithm as well as developed RAM 1.0 Graphical User Interface, respectively. RAM Model takes into account different ambient characteristics, meteorological … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Situation and Evaluation of Forest Harvesting Methods in TurkeyMurat Demir, Tolga OzturkThe present study summarize and evaluate major problems of timber harvesting in Turkey and the future principles and objectives have been defined. Timber harvesting in Turkey is still carried out by manual methods due to economical, social and environmental constraints. Almost 80% of harvesting activities are mechanized in many developed countries while this value is only 5% in Turkey. Overall … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistribution of Biomicrofacies and Cement Types in the Changxing Formation (Upper Permian), Western Hubei-eastern Sichuan Provinces, South ChinaMutwakil Nafi, Xia WenchenThe Changxing formation is subdivided into lower, middle and upper parts. Four types of microfacies were recognized in the Changxing formation. They include SMF-3, SMF-6, SMF-7 and SMF-19. The Changxing Formation is composed of deep basin margin, platform margin and open restricted platform environments. The lower, middle and upper parts are dominated by deep basin margin facies, platform margin facies … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,000 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrometric Methods Used to Determine Heavy Metals and Total Cyanides in Accidental Polluted SoilsA. Mihaly-Cozmuta, L. Mihal Cozmuta, V. Viman et al.The study presents the level of soil pollution in the area adjacent to three sedimentation ponds as a result of an environmental accident. Soil samples from various sites have been collected and analyzed to determine the concentration of heavy metals (Cu, Pb, Zn) and total cyanides. The analysis methods used were ICP-AES for heavy metals and the colorimetric for total … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of a New Model for Evaluation of Iran Ecological Capabilities in Order to Establish Services and Civil Development ApplicationJ. Nouri, S. A. JoziThis study is aimed to design a new model for service and civil development application in order to be used in evaluation of Iran ecological capability studies. For this purpose in the first step, the frequency of sustainable and unsustainable ecological factors in Iran was known. In the next step, the Delphi method was used which is itself a branch … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,513 accessesView PDFCite
