BACKGROUND It is still inconclusive whether alcohol consumption affects the risk of thyroid cancer. We conducted a meta-analysis of available epidemiological data to address this issue. RESULTS Compared with nondrinkers, the pooled relative risks (RRs) and corresponding 95% confidential intervals (CIs) of thyroid cancer were 0.80 (95% CI 0.71-0.90) for any drinkers, 0.81 (95% CI 0.70-0.93) fo...

This paper describes a strategic level simulation model developed to help stakeholders understand the Los Angeles solid waste system. The model structure is based on a “recycling loop” incorporating five interconnected sectors: consumption, collection, processing, disposal, and production. The user interface includes eight strategic decision levers (product durability, waste in products and pac...

background: the objective of this study was to determine the heart rate and oxygen consumption of the elderly whilst frying. methodology: in 2010, a total of 31 subjects (11 males and 20 females) from sg. merab, selangor were participated in this study. they were aged between 60 to 83 years with a mean age of 67.06 years. they were asked to perform five minutes frying task and data were measure...

BACKGROUND Accurate estimates of the impact of alcohol on overall and age-specific mortality are crucial for formulating health policies. However, different approaches to estimating alcohol-attributable mortality provide different results, and a detailed comparison of age-specific estimates is missing. METHODS Using data on cause of death, alcohol consumption, and relative risks of mortality ...

beet armyworm,spodoptera exigua (hübner) (lep.: noctuidae), is a polyphagous insect pest inflicting substantial economic damage to many crops including corn, cotton, beet, tomato, celery, lettuce and alfalfa. in this study the effect of 10 commercial hybrids of corn (sc700, dc370, sc704, sc260, sc500, keynes540, keynes410, ksc260, ksc400 and ksc301) on the beet armyworm was investigated through...

This paper proposed a new method to determine the neuronal tuning curves for maximum information efficiency by computing the optimum firing rate distribution. Firstly, we proposed a general definition for the information efficiency, which is relevant to mutual information and neuronal energy consumption. The energy consumption is composed of two parts: neuronal basic energy consumption and neur...

INTRODUCTION It is unknown whether an extremely high heart rate can affect oxygen pulse profile during progressive maximal exercise in healthy subjects. OBJECTIVE Our aim was to compare relative oxygen pulse (adjusted for body weight) curves in athletes at their maximal heart rate during treadmill cardiopulmonary exercise testing. METHODS A total of 180 elite soccer players were categorized...

To justify substantial emission reductions, recent literature on cost-benefit analysis of climate change suggests discounting environment consumption with an environmental discount rate instead of a consumption discount rate that is usually used in cost-benefit analysis. The present study clarifies that whether or not this dual-rate discounting approach succeeds in justifying substantial emissi...
