Research ArticleOpen accessIn the abstractChemical and Biological Warfare: Should Rapid Detection Techniques Be Researched To Dissuade Usage? A ReviewMark R. Hurst, Ebtisam WilkinsChemistry, microbiology and genetic engineering have opened new doorways for the human race to propel itself to a better future. However, there is a darker side to Bioengineering. One element of this is the manufacture and proliferation of biological and chemical weapons. It is clearly in the interest of humankind to prevent the future use of such weapons of mass … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Rainfall-runoff Models to Zard River Catchment'sM. B. Rahnama, G. A. BaraniRainfall-runoff models are nonlinear processes according to the sequential and spatial distribution of the rainfall. So, it is difficult to explain the response of catchments systems with the simple models. In the present work simulation of the rainfall-runoff processes have been carried out by the Artificial Neural Networks (ANN) and the HEC-HMS models. The ANN models of Multi Layer Perceptron … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,535 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Micromechanisms of Hydrogen Plastification and Embrittlement of Some Technological MaterialsYu. S. Nechaev, T. N. VezirogluSome fundamental problems of revealing micromechanisms of hydrogen plastification, superplasticity, embrittlement, cracking, blistering and delayed fracture of some technologically important industrial metallic materials are formulated. The ways are considered of these problems' solution and optimizing the technological processes and materials, particularly in the hydrogen and gas-petroleum industries, some aircraft, aerospace and automobile systems. …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransducer for Tension Force Measuring of Strip MaterialsEmad Said AddasiIn winding-up motor drive systems, such as that used in textile industry, it is very important to get a constant tension force for the winding strip material (thread) and to reduce its oscillations. This study recommends a transducer with a special design to be used in the mentioned motor drive systems. By using a piston damper, spring, levers, slider and … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,968 accessesView PDFCite
Research ArticleOpen accessIn the abstractWill Financial Analysts Mistake Stocks of Good Companies for Good Stocks? Evidence from Taiwan Stock MarketI-Ju ChenIt has been shown that the individual or institutional investors rely on the information provided by the financial analysts. A good stock recommended by financial experts is expected to make profit to the investors. However, due to the cognitive biases, the financial analysts or investors are probably confused in the firm characteristics between the good stocks and the stocks of … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,810 accessesView PDFCite

NezakatiChitgar artificial lake, located in the urban District-22 Municipality of Tehran northwest of Tehran, Iran is by volume l0 Million Cubic Meter (MCM), by depth average 10 meters (m.) and by area 225 hectares (ha) as the Iran’s largest man-made lake. The most important water resources of the district, which can support the lake water, are Kan River, municipal runoff, … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractFourier Series With Spectral and Wave Number DecompositionJung-Hua Chou, Raylin WuIn this study, the generic nature of Fourier series is pointed out and the requirement of dimensional homogeneity for physical systems is emphasized. By suitable application of non-dimensional variables, both time versus frequency and spatial versus wave number decomposition of Fourier series are included properly to put the physics involved into the right physical meanings. Furthermore, the high frequency noise … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,253 accessesView PDFCite
