Introduction: Today, philosophers have introduced the ultimate goal in higher education institutions as critical thinking skills. Thus this study was conducted to compare the critical thinking skills between years of education of bachelor students in Fasa University of Medical Sciences. Methods: This study was conducted on 150 Studying BSc students in various terms from Fasa University of Me...
in the present attempt, flow behavior and thermal convection of one type of nanofluids in a disc geometry was investigated using computational fluid dynamics (cfd). influence of gravity induced sedimentation also has been studied. the commercial software, fluent 6.2, has been employed to solve the governing equations. a user defined function was added to apply a uniform external magnetic field....
One of the causes of perturbation at vertical intakes is the happening of vortices with an air core. The vortices with an air core occur whenever the submergence of the intake is less than a critical value. Anti-vortex devices and specially plates are used to avoid the negative effects of the air-core vortices. If plates are used, then the geometry of them should be studied experimentally. Acco...
Doping Pr in 123-systems gives rise to some anomalies, such as critical Temperature suppression. Here, we show that a modification of hole localization theory based on a geometrical modeling by band percolation theory can put forward as a good explanation for the critical temperature suppression for the whole range of Pr-doping value. In this model the key concept of hole clustering is introd...
سنگ کلیه باتوجه به وضعیت اقتصادی واجتماعی جامعه جزء بیماریهای باشیوع بالارونده است.تفاوتهای جغرافیایی زیاددرشیوع سنگهای ادراری درکودکان بستگی به آب وهوا رژیم غذایی و فاکتورهای اقتصاداجتماعی دارد.تقریبا 7% از سنگهای ادراری درکودکان زیر16سال دیده میشود. تشکیل کریستالهای اسیداوریک، اگزالات کلسیم و سیستئین نیاز به اشباع موارد فوق در ادرار و تشکیل هسته های تشکیل دهنده سنگ می باشد. بعضی از مواد که ب...
We study the branching random walk on weighted graphs; site-breeding and edgebreeding branching random walks on graphs are seen as particular cases. Two kinds of survival can be identified: a weak survival (with positive probability there is at least one particle alive somewhere at any time) and a strong survival (with positive probability the colony survives by returning infinitely often to a ...
CONTEXT As a patient safety measure, laboratories are required to have a critical values policy by regulatory agencies. Unfortunately, little information is available on repeat critical values for the same analyte(s) on the same patient. OBJECTIVE To investigate the occurrence and distribution of repeat critical values and the relationship between the frequency of such values and patient outc...
In this paper, based on variational methods and critical point theory, we guarantee the existence of infinitely many classical solutions for a two-point boundary value problem with fourth-order Sturm-Liouville equation; Some recent results are improved and by presenting one example, we ensure the applicability of our results.
طرح مسئله : جهانی شدن یکی از مفاهیم کلیدی در تعیین کننده های اجتماعی سلامت بوده و بر سلامت جوامع بشری اثر گذار است. در این مطالعه به بررسی ساز و کار اثر جهانی شدن بر جنبه های مختلف سلامت از مسیر فقر و نابرابری پرداخته ایم. روش : این مطالعه از نوع همبستگی – اکولوژیک بوده و داده های موجود را تحلیل کرده ایم. سنجش جهانی شدن، جهانی شدن اقتصادی، اجتماعی و سیاسی از طریق شاخص kof index of globalizatio...
background: routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. we figure that repeat testing of critical laboratory values has any benefits or not. methods : we examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white b...
