Research ArticleOpen accessIn the abstractSpeciation of Chromium in Bottom Ash Obtained by the Incineration of the Leather Waste ShavingsK. louhab, H. AkssasThe evolution of bottom ash morphology and chromium metals behavior during incineration of a leather waste shavings at different incineration temperature have been studied. The Cr, Ca, Mg, Cl rates in bottom ashes, flay ashes and emitted gases in different incineration temperature of the tannery wastes are also determined. The morphology of the bottom ashes obtained by incineration at different … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,490 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhase Transition in Φ6 PotentialHatem WidyanScalar field theory with an asymmetric potential was studied at zero temperature and high-temperature for Φ6 potential. The equations of motion are solved numerically to obtain O(4) spherical symmetric and O(3) cylindrical symmetric bounce solutions. These solutions control the rates for tunneling from the false vacuum to the true vacuum by bubble formation. The range of validity of the thin-wall … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 6,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating Methods of Estimation and Modelling Spatial Distribution of Evapotranspiration in the Middle Heihe River Basin, ChinaChuanyan Zhao, Zhongren Nan, Guodong ChengSeven models commonly used to estimate the daily reference evapotranspiration (ET0) were evaluated in the middle Heihe River Basin of the arid northwestern part of China. The objectives of the study are to choose the appropriate model for estimating the areal distribution of ET0 and to explain the spatial-temporal distribution of the same through GIS in the study area. The … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 6,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractPharmacodynamic Comparison of the Carbapenems Against E. coli and Klebsiella spp. Containing Extended spectrum β-lactamasesKathryn J. Eagye, Joseph L. Kuti, David P. NicolauCarbapenems are the treatment of choice for extended-spectrum β-lactamases (ESBLs). Ertapenem is a new member of the carbapenem class, and is often grouped with imipenem and meropenem as a recommended treatment for ESBLs. However, new in vitro data question ertapenem’s inclusion as a first line treatment for these bacteria, suggesting that ertapenem has a lower likelihood of obtaining appropriate pharmacodynamic … …American Journal of Infectious Diseases, Vol. 1, Issue 3 · 30 Sep 2005 · 6,890 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Environmental Non-Governmental Organizations in Natural Resources Management Extension (Case Study in Iran)Iraj M. Mohammadi, Mehrdad MirbodThis study describes the emergence, development and functions of Environmental Non-Governmental Organizations (ENGO) and addresses their role and impact in Natural Resources Management Extension (NRME) in Iran. The study also attempts to describe the collaboration and support of government organizations managing natural resources, mainly National Forest and Pasture Organization (NFPO) and Environmental Conservation Organization (ECO) and locally based ENGOs in … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 6,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractInduction of Micronuclei in Mice Lymphocytes Exposed to Microwave and TolueneS. B. Mortazavi, A. Safari, A. Khavanin et al.Increasing applications of microwave radiation are of great concern with regard to public health. Several studies have been conducted detect effects of microwave exposure genetic material leading to negative or questionable results. The Micronucleus (MN) assay which is proved to be a useful method for detection of radiation exposure-induced cytogenetic damage was used in the present study to investigate the … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,617 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrochemical Characteristics of Some Purpurins in Aqueous and Nonaqueous SolutionsFarouk A. Rashwan, Hossnia S. Mohran, Ahmed A. El-SamahyThe Electrochemical Impedance Technique (EIS) and the Cyclic Voltammetric method (CV) were used to investigate the behavior of purpurin (P), Anthrapurpurin (AP) and Benzopurpurin (BP) in aqueous and in N, N-dimethylformamide (DMF) media. In the CV experiments, both the radical and the dianion of these substances were assumed to form of limited stability due to chemical protonation. In case of … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,744 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Adaptive Routing Algorithm for Ad hoc Mobile NetworksHamed S. Al-BdourThis research has examined the issues of routing in multi-hop wireless networks of mobile nodes without the need for any existing network infrastructure or administration. This is called ad hoc. The key point of this research article are selecting routing protocols which adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Reversible Method of Epiphysiodesis-An Experimental Study in RabbitsMahmood Karimi-Mobarakeh, Reza Malekpour-Afshar, Nozar Nakhaee et al.Lower limb discrepancy and angular deformities are among the most common orthopedic problems in pediatrics. All methods for correction of these deformities are irreversible and the epiphyseal growth plate is arrested. Current study describes a new reversible method of epiphysiodesis. At the first step, we decided to examine angular deformity of the knee. Seven New Zealand white female rabbits with … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,208 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarthquake Airbags, New Devices to Save Lives in Earthquakes, Tornados and Similar Disasters Resulting from Building CrashesAmir Hashem Shahidi BonjarEarthquake Airbag (EA) is a new terminology being introduced for the earthquake literature of the world. According to literature surveys, this terminology has not been used previously. Based on many scientific reports, fatality rates are lower in vehicles equipped with airbags than unequipped ones. Accordingly, it was postulated that similar structures can be adopted in buildings to protect people and … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,532 accessesView PDFCite
