کانسار مس جیان در فاصله 195 کیلومتری شمال خاوری شیراز و در لبه خاوریپهنه دگرگونی سنندج-سیرجان درون مجموعه آتشفشانی-رسوبی دگرگون شده کمپلکس سوریان با سن پرموتریاس قرار دارد. سنگشناسی منطقه بیشتر شامل متابازالت، کلریت-کوارتزشیست،کلریت-مسکوویتشیست، میکاشیست و گرافیتشیستاست. پیریت مهمترین کانی سولفیدی و کالکوپیریت کانی اصلی مس در این کانسار است که در ساختارهای تودهای عدسی شکل تا به نسبت تخت ...
سنگهای آتشفشانی منطقه جنوب کرکس تحت تأثیر فرآیندهای تأخیری و نفوذ سیالات دگرسانکننده دچار دگرسانی گرمابی شدهاند. سنگهای آتشفشانی ائوسن در این منطقه ترکیب غالب اسیدی تا حدواسط دارند و ماگمای سازنده آنها نیز ماهیت کالکآلکالن دارد. دگرسانی در این منطقه نظم خاصی را دنبال نمیکند. پهنه پروپلیتیک بهصورت پراکنده بیرونیترین زون دگرسانی را تشکیل میدهد. در بیشتر موارد پهنه پروپلیتیک و آرژیلیک مر...
This study aimed to compare the resting energy expenditure (REE) of white and non-white severely obese Brazilian women. REE was examined in 83 severely obese Brazilian women (n = 58 white and 25 non-white) with mean (+/- SD) age 42.99 +/- 11.35 and body mass index 46.88 +/- 6.22 kg/m(2) who were candidates for gastric bypass surgery. Body composition was assessed by air displacement plethysmogr...

OBJECTIVE Obesity, insulin resistance, and diabetes disproportionately affect African-American (AA) women. Abnormal adipose tissue free fatty acid (FFA) release is associated with these conditions. Resting energy expenditure (REE) and sex predict FFA release in Caucasians, but whether this is true in AA is unknown. The sex-specific relationships between FFA release, REE, and race was compared. ...
Obesity is a risk factor for the onset of liver cancer in patients with cirrhosis. To prevent overfeeding and obesity, estimation of energy requirement is important, but energy expenditure in patients with liver cirrhosis has not been fully elucidated. This study aimed to investigate resting energy expenditure (REE) and energy intake in patients with cirrhosis and determine adequate energy inta...
Few ecotoxicological studies exist for rare earth elements (REEs), particularly field-based studies on their bioaccumulation and food web dynamics. REE mining has led to significant environmental impacts in several countries (China, Brazil, U.S.), yet little is known about the fate and transport of these contaminants of emerging concern. Northern ecosystems are potentially vulnerable to REE enr...
OBJECTIVE To investigate the relationship between resting energy expenditure (REE) and patterns of obesity/regional fat parameters in Chinese adults. METHODS Body mass index (BMI), fat mass (FM), fat-free mass (FFM) were assessed in 109 Chinese adults (52 men and 57 women), and their abdominal visceral adipose tissue area (VA) and subcutaneous fat area (SA) were measured using magnetic resona...
BACKGROUND Inflammation is associated with increased resting energy expenditure (REE) in patients with chronic kidney disease. Oxidative stress, on the other hand, appears not to increase REE. Smoking is a common mechanism for generating oxidative stress and inflammation. Whether smokers have increased REE and if so, whether it is accounted for by the pro-oxidant and inflammatory state is not k...
The rare earth elements (REE) form the largest chemically coherent group in the periodic table. Though generally unfamiliar, the REE are essential for many hundreds of applications. The versatility and specificity of the REE has given them a level of technological, environmental, and economic importance considerably greater than might be expected from their relative obscurity. The United States...
