در این تحقیق بهمنظور روشن شدن تاریخچه و چگونگی درمان انواع تنگینفسها و آسم، سیرتکاملی درمان از دوران باستان تا پایان سال 1323 هجری قمری مطابق با 1905 میلادی (دارالفنون ناصری) بررسی شد. شایعترین بیماریهایی که پزشکان سنّتی به بیماریهای دستگاه تنفسی بهشرح و بحث دربارهی آنها پرداختهاند، شامل: انتفاخ الریه (آمفیزم ریوی)، انتفاخ الصدر (پنوموتراکس)، نفث الدم (هموپتیزی)، هموراژیهای دستگا...
Introduction: Scientometrics allows analyzing scientific publications productivity and impact through bibliometric computational techniques. Objective: To propose a multidimensional methodology in order to obtain the scientometric profile of National Cancer Institute (INCan), Mexico, rank it with regard other national health institutions. Method: Using LabSOM software ViBlioSOM based on artific...
The Royalloy steel was boronized at 1173, 1223, 1248, 1273 or 1323 K for 1, 3, 5, 7 10 h using a Durborid powder mixture. samples were analyzed by scanning electron microscopy, X-ray diffraction and Vickers microhardness testing. kinetic activity of layers growth obeys the parabolic law, maximum thickness 182 ± µm. FeB makes up to 40% total layer thickness. obtained have two phases, which compo...
CoCrFeMoNi high entropy alloys (HEAs) exhibit several promising characteristics for potential applications of temperature coating. In this study, metastable intermetallic phases and their thermal stability high-entropy alloy CoCrFeMo0.85Ni were investigated via microstructural analyses. Solidus liquidus temperatures determined by differential analysis as 1323 °C 1331 °C, respectively. Phase tra...
To evaluate the impact of PM2.5 air pollution on atherogenic processes in modernizing Southern versus Northern China, we studied 1323 asymptomatic Chinese and China 1996–2007. exposure metabolic syndrome (MS) were noted. Brachial flow-mediated dilation (endothelial function FMD) carotid intima-media thickness (IMT) measured by ultrasound. Although age gender similar, was higher than China. The ...
Effects of pre-aging Corson alloys with high concentrations Ni and Si (Cu–4.2 mass%Ni–0.93 mass%Si) followed by heavy cold rolling full-aging on strengthening were systematically investigated. Especially, development heterogeneous-nano (HN) microstructure was focused. And the relationship mechanical/electrical properties precisely examined. The pre-aged exhibited a considerable after 90% rollin...

Abstract The hydrogen economy has been a major vision for many futurists, over half century, as way to transition world not dependent on fossil fuels (Bockris, Science 176:1323, 1972). As with views, the complete perspective from which all potential change can be viewed. It therefore passionate if somewhat fundamentalist following. This paper outlines how electrification now superseded much of ...
