Research ArticleOpen accessIn the abstractPrevalence of Beta-hemolytic Streptococcus Carrier State and its Sensitivity to Different Antibiotics among Guidance - School Children in Kerman-IranFatemeh Nabipour, Mohammadali TayarzadehGroup A β-hemolytic streptococcus is the most frequently isolated pathogen in acute pharyngitis and pharingotonsilits Cases in school - aged children. Resulting in dangerous complications such as rheumatic fever and glomerulonephritis, diagnosis and treatment of the disease would be of great importance. The aim of this study was determination of the frequency of group A β-hemolytic streptococcus carriers in middle … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 6,777 accessesView PDFCite
Research ArticleOpen accessIn the abstractERCP Related SepsisIffet Palabıyıkoglu, Emin Tekelı, Derya Aysev et al.Endoscopic procedures performed worldwide have increased considerably in recent years. In addition to diagnosis, many cases previously necessitating surgery now often can be carried out by endoscopic techniques. However, endoscopy has introduced its own infection risk. Most reports of gastrointestinal endoscopy-associated infection describe sepsis after endoscopic retrograde cholangiopancreatography (ERCP) in patients with biliary tract obstruction. During this study, which was … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 7,016 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Optical and Physical Roles of a Dielectric Laser Dye Solvent Which Affects on the Dye Laser OperationRiyad A.M. GhazyIt is well known that when the pump laser beam incidence on the laser dye liquid it will be absorbed. This absorption tends to heat the laser active medium, which is the laser dye solution. In view of this the correlated property of that active medium well change tends to shift the operated frequency and wavelength. Therefore, one of most … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Performance of Traffic Dependent Outage Rate Cellular SystemHussein M.A. Basi, M. B.R. MurthyThe designers of a mobile cellular system must evaluate the possible configurations of the system components and their characteristics in order to develop a system with greater efficiency. The useful parameters to estimate performances of the system are voice quality, frequency spectrum efficiency and grade of service (GOS). In this study, a scheme proposed to reduce the lost calls and … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeparin-PF4 Antibodies in Heparin Induced Thrombocytopenia: Its Relationship with FcgRIIa PolymorphismMeganathan Kannan, Firdos Ahmad, Sarfraz Ahmad et al.We did the pilot study, in an attempt to determine the prevalence of HIT in Indians and determine its relationship, if any, to FcγRIIa polymorphism, the occurrence of heparin-induced thrombocytopenia (HIT) was investigated in 33 Indian patients undergoing cardiovascular surgery (CVS) who received unfractionated heparin (UFH). Platelet counts were performed prior to the initiation of UFH therapy and 5-16 days, … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,432 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Current Sensor for IDDQ Testing of CMOS ICMohd Liakot Ali, Nurul Huda KhamisThis study presents the design of an off-chip current sensor for IDDQ testing of CMOS (Complementary Metal-oxide Semiconductor) ICs (integrated circuit). It provides a linear voltage signal of IDDQ current with a conversion factor of 5 mV/μA without any amplification. A voltage-controlled switch is used to bypass the transient current peaks. It has also been shown that the sensor is … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,834 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simple Scheme for Improved Performance of Fixed Outage Rate Cellular SystemHussein M.Aziz Basi, M. B.R. MurthyThe traffic characteristic of mobile cellular systems is rather distinct from that of a fixed telephone network. However the system planning and design are still carried out with the tools of conventional traffic theory. In the recent days much work is being done in the performance evaluation of mobile or cellular communication systems in order to develop a system with … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,078 accessesView PDFCite
