this study tries to make a distinction between factors affecting adopters and non-adopters of domestic rainwater harvesting (drwh) in golestan province, iran. in order to better comprehend the differences, nine dimensions were considered in this study, including (1) social background (including respondents’ demographics, water sources, issues in accessing water sources, primary awareness of the...
سابقه و هدف: استافیلوکوک اورئوس یکی از مهم ترین عفونت های بیمارستانی می باشد که روز به روز بر مقاومت آنتی بیوتیکی آن به گروه بتالاکتام و وانکومایسین افزوده می شود. در این مطالعه ضمن بررسی فراوانی سوش های استافیلوک اورئوس بیمارستانی مقاوم به اگزاسیلین و وانکومایسین، میزان همخوانی دو روش disk diffusion و e test در تعیین حساسیت آنتی بیوتیکی مورد بررسی قرار گرفت.روش بررسی: در این مطالعه مقطعی، 100ن...
conclusion our preliminary results have shown that although there is some overlap between benign and malignant tumors, adding dwi, mr imaging to routine soft tissue tumor protocols may improve diagnostic accuracy. results there was only one patient with a malignant cystic tumor and was not included in the statistical analysis. the median adc values of benign and malignant tumors were 2.31 ± 1.2...
background: ornithobilharziosis as one of the parasitic infections may give rise to serious economic problems in animal husbandry. the aim of the study was to prepare and compare the somatic and excretory-secretory (es) antigens of o. turkestanicum in gel diffusion test. methods: excretory-secretory (es) and somatic antigens of ornithobilharzia turkestanicum were prepared from collected worms ...
evaporation of micro-liter drops from solid surfaces at room condition is mainly governed by diffusion. therefore, there should be no difference between evaporation rate of sessile and pendant drops. however, some studies indicate a difference and explain the difference using buoyancy. the objective here is to reconcile the inconsistency in the literature. for that, first, by comparing two iden...
background and objective: reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by coagulase negative staphylococci (cons). the objective of the present study was to compare and evaluate the performance of disc diffusion and e test (epsilometer test) methods for antimicrobial testing of coagulase negative staph...
diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (om), microhardness depth profiling (hdp), scanning electron microscopy (sem), x-ray diffraction (xrd), glow discharge optical emission spectroscopy (gdoes), and secondary ion mass spectroscopy (sims). plasma nitri...

objectives: grewia paniculata (family: malvaceae) has been used to treat inflammation, respiratory disorders and fever. it is additionally employed for other health conditions including colds, diarrhea and as an insecticide in bangladesh. the aim of the present study was to investigate the antibacterial and cytotoxic activities of different extracts of grewia paniculata. materials and methods: ...
we derive error estimates in the appropriate norms, for the streamlinediffusion (sd) finite element methods for steady state, energy dependent,fermi equation in three space dimensions. these estimates yield optimal convergencerates due to the maximal available regularity of the exact solution.high order sd method together with implicit integration are used. the formulationis strongly consistent...
