OBJECTIVE To examine whether the low birth weight (LBW) paradox exists in Brazil. METHODS LBW and cesarean section rates between 1995 and 2007 were estimated based on data from SINASC (Brazilian Live Births Database). Infant mortality rates (IMRs) were obtained using an indirect method that correct for underreporting. Schooling information was obtained from census data. Trends in LBW rate wer...
تحقیقات اخیر روی روشهای عددی، بر ایده استفاده از روشهای بدون شبکه{meshfree methods} برای حل عددی معادلات دیفرانسیل با مشتقات جزئی تاکید می کند. یکی از ویژگی های رایج همه روشهای بدون شبکه، توانایی آنها در ساخت تقریب تابع، تنها با استفاده از اطلاعاتی در یک مجموعه از داده های پراکنده می باشد. تعدادی از روشهای بدون شبکه عبارتند از: روش هیدرودینامیکهای ذره ی هموار{smooth particle hydrodynamics ...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
background:growth is one of the most important indices in child health. the best and most effective way to investigate child health is measuring the physical growth indices such as weight, height and head circumference. among these measures, weight growth is the simplest and the most effective way to determine child growth status. weight trend at a given age is the result of cumulative growth e...
هدف از ارایه این پایان نامه بررسی روشی است برای حل معادلات دیفرانسیل غیرخطی که شکل عمومی آنها بصورت lu+nu=g(t) می باشد. در این معادله n یک عملگر غیرخطی و l یک عملگر دیفرانسیلی خطی می باشد. این روش تحت عنوان روش تجزیه (آدومیان) بررسی می شود. در این روش u رابه صورت u تجزیه می کنیم. همچنین ترکیب غیر خطی nu را بصورت an (u , u , ... , u ) نمایش می دهیم که a ها چند جمل...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
