This study aimed to determine the levels of health-related behaviours (physical activity, screen exposure and sleep status) among Chinese students from primary, secondary high schools during pandemic COVID-19, as well their changes compared with status before pandemic. A cross-sectional online survey 10,933 was conducted 10 in Guangzhou, China, between 8th 15th March, 2020. After getting informed consent student's caregivers, an questionnaire designed used obtain time spending on 3 months...
A mixed-TEHD (thermal elastohydrodynamic) model was developed for journal bearings working at large eccentricity ratios in order to facilitate a better understanding of mixed-lubrication phenomena conformal-contact elements. The consists process that considers the roughness effect and asperity contact, thermal temperature analyses, thermal-elastic deformation calculations. In this model, interactive journal, lubricant, bearing were treated as an integrated system. Finite-element,...
To promote the development of Lewis acidic chloroaluminate ionic liquids, it is necessary to get a deeper insight into their physicochemical properties and molecular structure. In this work, densities, viscosities, conductivities 1-butyl- 1-hydrogen-3-methylimidazolium with different mole fractions AlCl3 were measured in temperature range from (293.15 343.15) K. Meanwhile, excess molar volume viscosity deviation values for binary mixtures 1-butyl-3-methylimidazolium liquids also obtained....
To promote heat dissipation in power electronics, we investigated the thermal conduction performance of Sn-Bi solder paste between two Cu plates. We measured resistance used as interface material (TIM) by laser flash technique, and a less than 5 mm2 K/W was achieved for TIM. The also showed good reliability terms after cycling, indicating that it can be promising candidate TIM electronics applications. In addition, estimated contact at plate with assistance scanning acoustic microscopy....
The effect of substituting CaO with BaO and CaO/Al2O3 ratio on the viscosity CaO–BaO–Al2O3–CaF2–Li2O mold flux system was studied by rotational method. results showed that increased increasing as a substitute for CaO, while decreased increase in ratio. viscous activation energy slags is from 92.1 kJ·mol−1 to 133.4 kJ·mol−1. Either Arhenius or Weymann–Frenkel equation can be applied establish prediction model. In this paper, new optical basicity regard Al2O3 an acidic oxide were modified NPL...
Abstract Background Although studies have indicated that extreme temperature is strongly associated with respiratory diseases, there a dearth of focused on children, especially in China. We aimed to explore the association between and children’s outpatient visits for diseases seasonal modification effects Harbin, Methods A distributed lag nonlinear model (DLNM) was used effect daily among as well effects. Results Extremely low temperatures were defined 1st percentile 2.5th temperature. high...
The analysis of magnetic particle dynamics in a rotating field and the exploration agglomeration mechanism are crucial for effectively reducing strong minerals improving sorting efficiency. forces acting on particles were analyzed this study. A 3D model was built to simulate complex interaction between two using COMSOL Multiphysics finite element simulation software. It shows that number periods change spiral period, velocity, acceleration remains consistent under different conditions....
