tuberculosis remains a major public health problem in both developing and developed countries. drug-resistant tuberculosis is an increasing health problem and serious challenge to tuberculosis (tb) control programs. information about the susceptibility pattern of mycobacterium tuberculosis isolates against anti-tuberculosis drugs is an important aspect to tb control. the objectives of the study...
BACKGROUND: Staphylococcus aureus is a highly versatile pathogen of a large number of domestic ani- mals, including avian species. There is limited information about S. aureus isolated from companion and wild birds in Iran. OBJECTIVES: The aim of this study was to determine drug resistance and random-amplified polymorphic DNA-PCR (RAPD-P...
Background: Enteropathogenic E.coli (EPEC) pathotypes are belonging to enterobacteriaceae family that is known as agent of gastroenteritis and diarrhea in under 5 year old children. These bacteria have high prevalence in developed and developing countries that may cause severe diarrhea even death. Prevalence and antibiotic resistance patterns of these pathotypes are different in various r...

control of insect pests of agriculture, economic, and medical importance usually focuses on the use of insecticides. the susceptibility levels of eleven strains of german cockroaches, blattella germanica (l.), were compared with a standard susceptible strain against permethrin and fipronil. the strains were collected from nine infested students’ dormitories and two infested hospitals in tehran,...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
as the canon is shaped by white male standards rewriting the canonical works of literature is one of the ways through which postcolonial writers subvert the authority of the masters. writing in the language of the masters the colonized writers use the very suppressive tool in the hands of the masters i.e. their language to question the validity of their norms. regarded by most critics to be the...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
