growing population and increasing urbanization has led to the expansion of informal settlements. informal settlements in developing countries, more than other urban tissues are exposed to various risks and natural disasters. this type of settlements, often develop and spread without regard to natural hazards, with no specific plan and no attention to regulations. expansion of informal settlemen...

this research work is devoted to the development of a mathematical model for the simulation of the flow of polymeric melts through the die region of extruders. a set of governing equations are solved using finite element method. standard galerkin technique is used in conjunction with the mixed scheme to solve the flow equation. due to the non-linear nature of global equations, the picard iterat...

Isoniazid, is the only antituberculous drug for which the relation between lack of virulence and acquisition of resistance was associated. INH-resistant mutants were shown to contain defective katG gene. Classical studies showed that INH-resistant south Indian isolates have lower virulence in guinea pigs and higher susceptibility to H2O2. It is of interest to assess the virulence in south India...

conclusions antibiotic resistance gene cassettes may be carried on integron or other genetic elements. the purpose of this study was to detect integron or genomic islands involved in antibiotic resistance profile of the isolates of h. influenzae collected in this study. results of the twenty isolates, all (100%) were resistant to clindamycin, chloramphenicol and tetracycline, 95% to amoxicillin...

objective: genes involved in bone and tissue remodelling in the vertebrates include matrix metalloproteinase-9 (mmp-9), receptor activator of necrosis factor κ-β (rank), cathepsin-k (ctsk) and tartrate-resistant acid phosphatase (tracp). we examine whether these markers are expressed in cells of zebrafish embryos of 1-5 days post fertilization. we also examine adult scales, which are known to c...

From Sep. 1984 to Aug. 1990,99 patients were treated for ureteral stone using the urekroscope. In five patients ureteroscopy was repeated for a second stone. In one patient the procedure was diagnostic in nature and in the rest of the patients it had a curative value. In 60 patients the stone was removed by electrohydraulic and basket combination and in25 cases, dilatation alone was enough...
