Research ArticleOpen accessIn the abstractModelling the Effect of Salinity on the Multivariate Distribution of a Water Quality IndexDaniela cocchi, Michele scagliariniSalinity is a tracer of water and nutrient flows and is employed in studies on coastal environment to establish the coastal or remote origins of pollutants and nutrients. The present article analyses the effects of salinity on the multivariate distribution of the Trophic Index TRIX. The approach taken is based on a multivariate nested model with salinity as an explicative … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 5,917 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal-time Optimistic Concurrency Control based on Transaction Finish DegreeHan Qilong, Hao ZhongxiaoConcurrency control is one of the main issues in the studies of real-time database systems. Optimistic concurrency control algorithms have the attractive properties of being non-blocking and deadlock-free. However, they have the problems of late conflict detection and transaction restarts. Although the number of transaction restarts is reduced by dynamic adjustment of serialization order in real-time database systems, they are … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,689 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Mutagenesis of Streptokinase Producing BacteriaThaer Taleb Abed Abdelghani, Adinarayana Kunamneni, Poluri EllaiahOf 103 β-haemolytic Streptococci (with haemolytic activity) in total were isolated from different samples of blood and biomass from infected throat, 47 isolates exhibited streptokinase (SK) activity. T3, identified as a new variant of Streptococcus equisimilis, was found to be excellent SK producer in submerged fermentation and was selected for strain improvement studies. This strain was mutagenized by UV and … …American Journal of Immunology, Vol. 1, Issue 4 · 31 Dec 2005 · 7,794 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Short Time Morphine Addiction on the Kidney Tissue in RatReza Malekpourafshar, Hamid ZeinalinejadOpium is an important substance that abuses and has very pharmacological and pathological effects. Morphine is the main substance of opium. In the recent study, it has been tried to identify the short effects of morphine on the kidney pathology of Rats. The randomized double blind study was designed. Twenty rats were selected and divided in two groups and maintained … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 4 · 31 Dec 2005 · 6,403 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Evolutionary Fitness of Bounded Rationality: Heterogeneous Populations in Antagonistic InteractionsTassos PatokosConventional game theory assumes hyper-rational players, while evolutionary game theory abandons the assumption. This paper studies what happens when agents of both profiles co-exist and get engaged in a series of antagonistic interactions (the Hawk-Dove game). It is shown that if rational agents are perfectly informed as to the type of their opponent, they find it optimal to always be … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 1 Dec 2005 · 8,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Effect of Counterface Materials on Interface Temperature and Friction Coefficient of GFRE Composite Under Dry Sliding ContactN. S.M. El-Tayeb, B. F. Yousif, P. V. BrevernNowadays, there is an increase interest in polymeric composite materials for high-performance in many industrial applications. In other words, the tribo-studies on polymeric materials are growing fast to enhance the polymeric products such as bearings, seals, ring and bushes. The current work presents an attempt to study the correlation between the type of counterface material and frictional heating at the … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,026 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Absorption Coefficients and Thermal Diffusivity of Modulated Doped GaAlAs/GaAs Heterostructure by Photothermal Deflection SpectroscopyS. Aloulou, M. Fathallah, M. Oueslati, A. SfaxiWe report in this study theoretical and experimental studies of photothermal deflection spectroscopy (PDS) for planar doped heterostructures AlGaAs/GaAs. The PDS spectra at T=300K are recorded by varying the wavelength of the excited radiation for different modulation frequencies. They show two different regions related to the fundamental electronic transitions from GaAs and Si doped AlGaAs. The DX levels have been … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of the American with Disabilities Act on Public Education ExpendituresMark P. GiusSection 504 of the Rehabilitation Act of 1973 and the American with Disabilities Act (ADA) of 1990 were enacted in order to protect the rights of individuals with disabilities. These two laws have had a major impact on public schools, their offerings of services and their budgets. The purpose of the present study was to determine if passage of the … …Journal of Social Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 6,843 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Economic Model of Insider Trading with an Informed Third PartyNasser G. ElkanjThe fact that an insider gains only at the expense of an outsider, manipulative insider trading precipitates a conflict of interests. We model this conflict in an extended principal-agent framework to demonstrate that the endogenous demand for reliable information would limit the volume and persistence of manipulative insider trading. An important dimension of such an insider trading is that an … …Journal of Social Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 6,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractCiprofloxacin Does Not Exert Nephrotoxicity in RatsAsli Baykal, Figen Sarigül, G Süleymanlar et al.Ciprofloxacin, a member of the fluoroquinolone class, is an antibiotic used as a treatment for infections including the Anthrax bacteria. Studies concerning the safety and efficacy of ciprofloxacin have been controversial with respect to nephrotoxicity. Using rats orally treated with ciprofloxacin (400mg/kg/d), the effects of this drug were analyzed measuring several indications of nephrotoxicity: β-NAG, creatinine, blood urea nitrogen, and … …American Journal of Infectious Diseases, Vol. 1, Issue 3 · 30 Sep 2005 · 7,444 accessesView PDFCite
