background : these days, the antibiotic resistance of pseudomonas aeruginosa isolates to imipenem has significantly increased. therefore the study of resistance to imipenem in this organism to imipenem in determining the appropriate treatment is crucial and necessary. the goal of this study is to compare three phenotypic methods of e-test, disk diffusion and micro broth dilution in the study of...

an analytical solution of the equation describing diffusion of intrinsic point defects in semiconductor crystals has been obtained for a one-dimensional finite-length domain with the robin-type boundary conditions. the distributions of point defects for different migration lengths of defects have been calculated. the exact analytical solution was used to verify the approximate numerical solutio...

abstract aims: bovine mastitis continues to be the most costly disease to the dairy farmers. it dominates in iran as one of the most prevalent diseases in dairy cattle among the dairy farms. mastitis treatment with antibiotics leads to the development of antibiotic resistant strains and consumer health problem. this study was performed for the first time to analyze in vitro effects of hydro-alc...

background and objectives : resistance among bacterial isolates is the leading cause of increased mortality and morbidity worldwide. carbapenems once thought to be effective are becoming ineffective mostly due to the emergence of carbapenemase. this study was designed to determine in vitro efficacy of modified hodge test for detection of carbapenemase production in gram negative rods. material ...

in this work the mathematical model of a spatial pattern inchemical and biological systems is investigated numerically. theproposed model considered as a nonlinear reaction-diffusionequation. a computational approach based on finite difference andrbf-collocation methods is conducted to solve the equation withrespect to the appropriate initial and boundary conditions. theability and robustness o...

background following the tenets of world polity and innovation diffusion theories, i focus on the coercive and mimetic forces that influence the diffusion of mental health policy across nations. international organizations’ mandates influence government behavior. dependency on external resources, namely foreign aid, also affects governments’ formulation of national policy. and finally, mounting...

the kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18-crown-6 (l) through a bulk liquid membrane is studied experimentally and theoretically. the proposed model is based on the assumption of a pure diffusion of the complex salt [k·l]+scn¯ through the liquid membrane stagnant films at the interfaces. it illustrates the connection between liquid-liquid extraction equilib...

a series of curcumin derivatives containing heterocyclic moiety have been synthesized and evaluated for their antibacterial activities. the chemical structures of the synthesized compounds were verified on the basis of spectral data and elemental analyses. investigation of antimicrobial activity of the derivatives demonstrated the ability to inhibit gram-positive microorganisms with zone of inh...
