RISHow Did Air Pollution Change during the COVID-19 Outbreak in China?
Publisher: American Meteorological Society
Abstract: In early December 2019, an outbreak of the novel coronavirus pneumonia (COVID-19) occurred in Wuhan, Hubei Province, China, and spread fast throughout China. As of 15 June 2020, there have been about 84,000 confirmed cased ...
Homogenized Variability of Radiosonde-Derived Atmospheric Boundary Layer Height over the Global Land Surface from 1973 to 2014
Publisher: American Meteorological Society
Abstract: oundary layer height (BLH) significantly impacts near-surface air quality, and its determination is important for climate change studies. Integrated Global Radiosonde Archive data from 1973 to 2014 were used to estimate ...

Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this study was to apply a biodegradable dynamic fixation system (BDFS) for lumbar fusion between articular processes and compare the fusion results and biomechanical changes with those of conventional rigid ...
PM2.5 Pollution in China and How It Has Been Exacerbated by Terrain and Meteorological Conditions
Publisher: American Meteorological Society
Abstract: AbstractThe recent severe and frequent PM2.5 (i.e., fine particles smaller than 2.5 µm) pollution in China has aroused unprecedented public concern. The first two years of PM2.5 measurements in China are reported and ...
Effect of Cu on the Tribocorrosion Behavior of Antibacterial CoCrMo Alloys in Simulated Biological Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: CoCrMo alloy containing copper element can significantly improve the antibacterial property of the alloy. However, most metal implants often fail due to the presence of corrosion and wear. In this work, the electrochemical ...
