Research ArticleOpen accessIn the abstractA Hybrid Fuzzy Neural Networks for the Detection of Tumors in Medical ImagesN. Benamrane, A. Freville, R. NekkacheIn this study, we propose an approach to detect suspect zones or tumors in medical images. The idea is to define with precision the existence of different kinds of lesions using a hybrid system, which combines Fuzzy Neural Networks and Expert System. After applying a method of image segmentation to extract regions (by region growing algorithm or by mathematical morphology … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,873 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Laser Irradiation on the Structural and Electrical Properties of Co-Zn Ferrite Thin FilmNehad M. TashtoushThin films of irradiated and non-irradiated Co-Zn ferrite was prepared by the thermal evaporation method on a glass substrate. The samples were annealed at 200°C, 400°C and 600°C for 1hr. The XRD analysis of all kinds of films, prepared for this study, shows that the spinel phase is almost completed after annealing. The change of the XRD after annealing is … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,033 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Spectrophotometric Method for Determination of Iron in Herbs, Spices and Beans with 2,6-Diacetylprydine Dioxime and 2-Acetylpyridine MonoximeZ. R. Komy, E. A. Abu-Gharib, A. DesokyThe reaction of iron (II) with 2, 6-diacetylprydine dioxime (H2dapd) and 2-acetylprydine monoxime (Hapm) in 10% and 60% v/v ethanol-water solution at pH 2.5 and 7.5, respectively, were studied using direct and first derivative spectrophotometry. Fe (III) is reduced by H2dapd and gives iron (II) complex. A simple, rapid, selective and sensitive method for the determination of Fe (II), Fe … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,960 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Investigation of the Relationship among Analyst Following, Managerial Ownership and Firm Valuation: From the Perspective of Agency TheoryI. J. ChenIn this study, the relationship among analyst following, managerial ownership and firm valuation is investigated from the perspective of agency theory by using a nonlinear simultaneous equation model. The data from the Taiwan stock market verify the proposed hypotheses with a nonlinear three-stage least-square procedure. The empirical results show that managerial ownership (serving an internal monitoring function) and number of … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,031 accessesView PDFCite
Research ArticleOpen accessIn the abstractProfit Analysis of A Two Unit Cold Standby System with Preventive Maintenance and Random Change in UnitsKhaled M. EL-Said, Mohamed S. EL-SherbenyThis study discusses the reliability of two units cold standby system with single repair. For achieving high reliability of the system, the operative and the standby units are interchanged at random epochs and additional preventive maintenance of operative and the standby units also. After the repair, the unit is sent for inspection to decide whether the repair is satisfactory. In … …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,880 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Approach for Authentication TechniqueAlaa H. Al-Hamami, Saad A. Al-AniOne of the serious problems is how to authenticate the passport document for its holder. The major factor of this authenticity is the corresponding of the Passport's photo with its holder. Most of the Passport document contains a holder's signature in addition, of course, to the full name. We propose a firm authentication method by extracting some features for the … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 7,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteraction of a C-terminal Truncated Hepatitis C Virus Core Protein with Plasmid DNA Vaccine Leads to in vitro Assembly of Heterogeneous Virus-like ParticlesNelson Acosta-Rivero, Joanna Poutou, Alexis Mussachio et al.Recently, it has been shown that HCV core proteins (HCcAg) with C-terminal deletions assemble in vitro into virus-like particles (VLPs) in the presence of structured RNA molecules. Results presented in this work showed that a truncated HCcAg variant covering the first 120 aa (HCcAg.120) with a 32 aa N-terminal fusion peptide (6xHistag-XpressTMepitope) interacts with plasmid DNA vaccine. Interestingly, the buoyant … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,754 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvidences of Hepatitis C Virus Replication in Hepatocytes and Peripheral Blood Monocuclear Cells from Patients Negative for Viral RNA in SerumViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.In this study, we examined the expression of hepatitis C virus (HCV) components in hepatocytes and peripheral blood mononuclear cells (PBMC) from patients positive for anti-HCV antibodies and negative for serum HCV-RNA. The samples obtained from 25 randomly selected patients (13 of 25 patients showed no histological evidences of chronic hepatitis and had normal serum ALAT and GGTP levels) were … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 7,164 accessesView PDFCite

Research ArticleOpen accessIn the abstractEffects of 50 HZ Magnetic Field on Some Factors of Immune System in the Male Guinea PigsH. Sedghi, S. Zare, H. Hayatgeibi et al.This study investigated the bio-effects of 50 Hz MF exposure on some Immunological factors (ACTH, cortisol and glucose levels) in male Guinea pigs. The capacity of 50 Hz Electromagnetic Fields (EMF) to interfere in the weakness of endocrine system has been a relevant fact into the scientific community, since we are more susceptible for this kind of exposure, in modern … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,997 accessesView PDFCite
