主动式立面经常在建筑中应用以促进建筑通风,为了保证这个过程的有效性,主动式立面必须朝南,然而这样,太阳辐射就会穿过玻璃直射室内,夏热季节则需要借助遮阳设施来遮挡,这可能会导致室内采光达不到标准。另一方面,采用主动式立面的建筑倾向于提高蓄热性能来强化夜间蓄冷效果,结果可能导致声回响时间延长,干扰人的工作。本文对采用主动式立面的办公建筑室内光、声和热环境性能进行测试评价,初步分析结果表明,主动式立面的优点是能够通过被动方式利用太阳能,提供高质量的工作环境,而如何确保空气流动路径通畅,以及如何采取相应措施减少声回响时间值得关注。

AIM To investigate hepatitis c virus(HcV) testing recommendations from the United States and other high-income *** A comprehensive search for current HcV testing recommendations from the top quartile of United Nations Human Development Index(HDI) countries(very high HDI) was performed using Google and reviewed from May 1-October 30, 2014 and re-reviewed April 1-October 2, 2017. RESULTS Of the 51 countries identified, 16 had HcV testing recom-mendations from a government body or recommendations issued collaboratively between a government and a medical organization. Of these 16 countries, 15 had HcV testing recommendations that were primarily risk-based and highlight behaviors, exposures, and conditions that are associated with HcV transmission in that region. In addition to risk-based testing, the HcV Guidance Panel(United States) incorporates recommendations for aone-time test for individuals born during 1945-1965(the birth cohort) without prior ascertainment of risk into their guidance. In addition to the United States, six other countries either have an age-based testing recommendation or recommend one-time testing for all adults independent of risk factors typical of the region. cONcLUSION This review affirmed the similarities of the HcV Guidance Panel's guidance with those of recommendations from very high HDI countries.

Background: Since the appearance of severe acute respiratory coronavirus 2 (SARS-coV-2) and the coronavirus disease 2019 (cOVID-19) pandemic, a growing body of evidence has suggested that weather factors, particularly temperature and humidity, influence transmission. This relationship might differ for the recently emerged B.1.617.2 (delta) variant of SARS-coV-2. Here we use data from an outbreak in Sydney, Australia that commenced in winter and time-series analysis to investigate the association between reported cases and temperature and relative ***: Between 16 June and 10 September 2021, the peak of the outbreak, there were 31,662 locally-acquired cases reported in five local health districts of Sydney, Australia. The associations between daily 9:00 am and 3:00 pm temperature (°c), relative humidity (%) and their difference, and a time series of reported daily cases were assessed using univariable and multivariable generalized additive models and a 14-day exponential moving average. Akaike information criterion (AIc) and the likelihood ratio statistic were used to compare different models and determine the best fitting model. A sensitivity analysis was performed by modifying the exponential moving ***: During the 87-day time-series, relative humidity ranged widely (c: 1,119.64) generalized additive model included 14-day exponential moving averages of 9:00 am temperature (P ction between these two weather variables (P ciated with cases no matter whether temperature was high or low. The effect of lower relative humidity on increased cases was more pronounced below relative humidity of about 70%;below this threshold, not only were the effects of humidity pronounced but also the relationship between temperature and cases of the delta variant becomes ***

Swimming is a very popular sport among adolescents in the US. Little is known about the diet of competitive adolescent swimmers in the US but data from other countries indicate several inadequacies, including excessive intake of fat and lower than recommended intake of carbohydrate and several micronutrients that may affect athletic performance and bone accrual. We assessed usual diet, using a food frequency questionnaire and calcium checklist, among 191 adolescent males and females [91 swimmers (mean 13.7, s = 2.5 years) and 100 non-athletes (mean 14.4, s = 2.8 years)]. For both males and females, swimmers and non-athletes generally had similar average intakes of macro- and micro-nutrients, including higher than recommended amounts of total fat (36%) and saturated fat (12%), and inadequate amounts of calcium, vitamin D, and daily servings of fruits, vegetables, grains, and dairy products. This first study of nutritional intake among adolescent swimmers in the US suggests that dietary habits of adolescents who swim competitively may jeopardize optimal athletic performance and place them at risk for future chronic diseases, including osteoporosis.

A lab-scale ethanol fermentation was investigated to determine where aflatoxin concentrated during each phase of production. Four corn samples with high levels of aflatoxin (ranging from 7750 – 17,208 parts per billion) and their replicates were compared with a replicated negative control. Fractions were taken from the fermented mash, distilled ethanol, stillage, and dried corn solids (DcS). These fractions were analyzed using two different immunoassay methods and liquid chromatography tandem mass spectrometry (Lc-MS/MS). Results indicated no aflatoxin was found in the distilled ethanol. Some aflatoxin (13%) was detected in the stillage, but most of the toxin was recovered in the DcSs ranging from 31% to 58%. A second series of experiments were conducted to investigate the effect of binders on dried distillers grains (DDGs). A brewers dried yeast anti-caking binder that contains glucomannon (MTB-100?), was mixed with contaminated DDGs. Addition of the binder showed a significant reduction in aflatoxin levels in comparison to a positive control. Aflatoxin binding at 2% binder w/w reached 72.5% and showed a minimal binding percentage increase of 80% at 6% binder w/w. Testing was also conducted to determine if environmental variables such as pH and temperature had any effect on the binding capabilities. Temperature near 0?c resulted in binding at 19.7% at a pH range of 6 to 8. Additionally, at a temperature of 40?c resulted in binding of 36%, 47%, and 45% at pHs 6, 7, and 8, respectively. These findings suggest that the addition of sorbents may be an effective way of salvaging contaminated DDGs.

Title: Integrating consistent Individualized carbohydrate-controlled Anti- Inflammatory Nutritional Plan (c-IcAN) in the Management of Prader-Willi Syndrome: A case Report. Prader–Willi syndrome (PWS) is a rare genetic disorder caused by a loss of function of specific genes on chromosome 15. Patients with this disease present unique challenges in management, particularly regarding obesity and nutritional regulation as the disease symptoms change depending on the age of the patient and the phase of the disease. These challenges pose critical stressors to caregivers and their families. We present a case report of a 5-year-old caucasian male diagnosed with PWS, exhibiting failure to thrive and uncontrolled weight gain. His caregiver was his elderly grandmother who, by her own admission, was ill-equipped to deal with the patient’s physical symptoms and his behavior in response to dietary restrictions. Through a multidisciplinary approach involving medical nutrition therapy (MNT) involving the implementation of a consistent Individualized carbohydrate-controlled Anti-Inflammatory Nutritional plan (c-IcAN), growth hormone supplementation, and behavioral interventions patient markedly improved physically and emotionally.
