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 ...

INTRODUCTION To investigate the clinical predictive values of the apparent diffusion coefficient (ADC) as a biomarker in radiation response of brain metastases. METHOD Forty-one patients with brain metastases treated with stereotactic radiosurgery (SRS) were imaged at baseline, one month post SRS, and six months post SRS using diffusion weighted MRI. The mean of ADC for metastases and tumor v...

This paper describes a study that focused on long-term web-supported learning diffusion among lecturers at Tel Aviv University (TAU), from an organizational point of view. The theoretical models we used to examine this process are Rogers' model for "Diffusion of Innovation" (1995) and Bass's "Diffusion Model" (1969). The study was conducted between the academic years 2000/01 and 2007/08. At tha...
