. این نهشته ها به صورت لایه ها و عدسی های چینه سان، در طول مرز بین کربنا ت های تریاس (سازند الیکا) و شیلی و ماسه سنگی ژوراسیک (سازند شمشک) گسترش یافته اند. مطالعات سنگ نگاری دلالت بر حضور بافت های اوئیدی، پیزوئیدی، نودولار، کلومورفیک جریانی، کلوفرمی، پورفیری دروغین، اسفنجی و پان ایدیومورفیک گرانولار درکانسنگ های این نهشته ها دارند. یافته های کانی شناسی نشان می دهند که کانسنگ ها حاوی کانی های اص...
یک افق بازماندی پرمین در 30 کیلومتری شمال خاور ملکان واقع شده که به شکل لایهچینهسان درون سنگهای کربناتی روته گسترش یافته است. از نظر کانیشناسی، این افق شامل کانیهای بوهمیت، دیاسپور، هماتیت، کائولینیت، روتیل، آناتاز، مونتموریلونیت، موسکویت، کلسیت و کلریت است. محاسبات مقادیر نورماتیو کانی...
Basic data on the resting energy expenditure (REE) of healthy populations are currently rare, especially for developing countries. The aims of the present study were to describe gender- and age-specific REE distributions and to evaluate the relationships among glycolipid metabolism, eating behaviors, and REE in healthy Chinese adults. This cross-sectional survey included 540 subjects (343 women...
REE (rare earth element) distribution coefficients (Kd) between the aqueous phase and montmorillonite surface were obtained to investigate the relation between the REE distribution patterns and the species of REE sorbed on the solid-water interface. It was shown that the features in the REE patterns, such as the slope of the REE patterns, the tetrad effect, and the Y/Ho ratio, were closely rela...
Heavy rare earth elements (HREE) are dominantly mined from the weathering crusts of granites in South China. Although weathering processes occur globally, no economic HREE resources of this type have yet been found outside China. Here, we report the occurrence of unidentified REE minerals in the granites from South Chinese deposits. They contain high levels of both HREE and light REE, but are s...
A predictive equation for resting energy expenditure (REE) was derived from data from 498 healthy subjects, including females (n = 247) and males (n = 251), aged 19-78 y (45 +/- 14 y, mean +/- SD). Normal-weight (n = 264) and obese (n = 234) individuals were studied and REE was measured by indirect calorimetry. Multiple-regression analyses were employed to drive relationships between REE and we...
Background The estimation of resting energy expenditure (REE) can be a valuable tool in developing programs for weight loss interventions and body composition management. REE prediction equations are a low-cost alternative to assess REE versus directly measuring REE, which typically requires expensive laboratory equipment. Though often used to estimate REE in active populations, the majority of...
PURPOSE The purpose of this study was: 1) To compare Resting energy expenditure (REE) in adult males with Becker's Muscular Dystrophy (BeMD, n = 21, 39 ±12 years) and healthy controls (CTRL, n = 12, 37 ±12 years) 2) Determine whether other physiological parameters correlate with REE in BeMD, and 3) Compare current prediction methods of REE with measured REE. METHODS REE was calculated via ind...
BACKGROUND Accurate and comfortable methods are needed to determine resting energy expenditure (REE) in older people who are characterized by a lowered metabolic rate. The portable SenseWear® armband (SWA) body monitor, worn on the right upper arm, can easily be used by this age group in an ambulatory manner. OBJECTIVE The purpose of this study was to evaluate the reliability and accuracy of ...
The concentration and distribution of rare earth elements (REE) in nasopharyngeal carcinoma (NPC) were measured to investigate connections with tumor size, lymph node metastasis, clinical stages, and Epstein-Barr virus (EBV) infection. There were 30 patients with NPC who met the criteria for inclusion in the present study. The EBV copy number, as well as the concentration and distribution of RE...
