Inhalation of indoor radon ((222)Rn) and thoron ((220)Rn) decay products is the most important source of exposure to ionizing radiation for the human respiratory tract. Decreasing ventilation rates due to energy saving reasons in new buildings suggest additional active mitigation techniques to reduce the exposure in homes with high radon and thoron concentrations but poor ventilation. Filtratio...

Hyperglycemia and insulin resistance are associated with morbidity mortality in critically ill patients, patients diabetes mellitus, alcoholic hepatitis, postoperative patients. Low GI (glycemic index) foods help control blood sugar resistance. Therefore, the goal of study was to determine glycemic index 4 kinds milk for subjects whose hyperglycemia affected treatment outcomes, namely, (proanec...

The 18th High-Efficiency Power Amplifier (HEPA) Student Design Competition (SDC) took place at the 2022 IEEE International Microwave Symposium (IMS), on 21 June 2022. competition was held by Theory and Technology Society (MTT-S) High-Power Techniques Committee (MTT-12) in collaboration with Keysight Technologies. This year’s event person after two years of virtual competitions (the 16th 17th HE...

In this paper, a homogenous multi-sensor fusion method is used to estimate the trueangular rate and acceleration with a combination of four low cost (< 10$) MEMS Inertial MeasurementUnits (IMU). An information form of steady state Kalman filter is designed to fuse the output of four lowaccuracy sensors to reduce the noise effect by the square root of the number of sensors. A hardware isimplemen...

Abstract Purpose Physical inactivity are complex problems to address. System thinking approach (STA) can be a solution take into account the diversity of upstream factors by identifying leverage points and potential co-benefits public policies. STA has not been explored at local level in France. Based on existing legislations regulations, this study aims providing system health-enhancing physic...

BACKGROUND The sports club is seen as a new relevant setting to promote health-enhancing physical activity (HEPA) among inactive population groups. Little is known about the effectiveness of strategies and activities implemented in the sports club setting on increasing HEPA levels. This study investigated the effects of Start2Bike, a six-week training program for inactive adults and adult novic...

This study was designed to evaluate the measuring range and lowest limit of detection of Bacillus endospores in the ambient room air when the Sartorius MD8 sampler, and two different culture methods for bacterial enumeration were used. Different concentrations of bioaerosol were generated inside the test chamber filled with either the high-efficiency particulate air (HEPA)-filtered air or with ...

Exposure to expired particles and droplets carrying infectious viruses is a primary transmission pathway for respiratory diseases. Removal of via filtration from volume can drastically reduce the exposure viruses, but may remain active on surfaces as potential resuspension or fomite risks. Here, we report development macroscopic carbon nanotube air filters synthesized using ultra-thin electrica...
