In this work we study the effect of some electrical prosperities on synthetic rubber reinforced with carbon black diluted in heptanes with concentrations from 0.2% gm/mole to 2.0% gm/ mole in temperatures range (100, 150, 200, 250, 300) C associated with amount weight of black carbon 5wt% added to the diluted rubber. The results of electrical properties measurement of Buna rubber reinforced wit...

In this paper, utilization of clustering algorithms for data fusion in decision level is proposed. The results of automatic isolated word recognition, which are derived from speech spectrograph and Linear Predictive Coding (LPC) analysis, are combined with each other by using fuzzy clustering algorithms, especially fuzzy k-means and fuzzy vector quantization. Experimental results show that the ...

زمینه و هدف: یکی از راهکارهای مناسب برای محافظت در برابر تأثیرات نامطلوب فشار اکسایشی ناشی تمرینات ورزشی طولانی‌مدت شدید، به‌کارگیری تدابیر تغذیه‌ای سالم استفاده مکمل‌های ضداکسایشی است. هدف این پژوهش بررسی اثر مصرف عصارة عناب طی دو نوع تمرین تناوبی استقامتی شدید بر شاخص‌های بافت کبد موش‌های صحرایی نابالغ نر بود.مواد روش‌ها: 72 سر موش نژاد ویستار با سن 22 روز میانگین وزنی 475/7 ± 64/60 گرم پس وز...

زمینه و هدف: بیماری کبد چرب غیرالکلی رایج‌ترین کبدی است که در حال پیشرفت بوده بیش از یک‌چهارم مردم جهان را درگیر خود ساخته است. این پژوهشگران معتقدند فعالیت ورزشی استفاده داروهای گیاهی با خواص ضدچربی ضداکسایشی می‌تواند به‌عنوان درمان مکمل، سودمند باشد. بنابراین، هدف پژوهش تعیین آثار هشت هفته تمرین هوازی یا مصرف عرق آرتیشو بر سطوح چربی سرمی آنزیم‌های زنان مبتلا به بود. مواد روش‌ها: بدین‌منظور، 2...

Three strains of facultatively anaerobic thermotolerant and moderately halophilic bacteria were isolated from two Jordanian hot spring locations. The novel Bacillus strains were short rods, Gram-positive, motile and spore formers. The strains were capable of anaerobic (but not aerobic) growth at 63C, moderately halophilic, able to grow at NaCl concentration range of 12 15 % and at temperatures ...

Previous studies have reported results on 24-hour ambulatory blood pressure (ABP) in Europe and Japan, but no data exists from South America. In this study, we conducted a population survey to identify reference values and to compare ambulatory blood pressure with clinic, home, and self-measured values. A random sample of 2650 adults was selected among 190 000 people covered by our prepaid heal...
