In order to accurately calculate the meshing efficiency of the new internal S-gears, a time-varying friction model of the elastohydrodynamic lubrication is established considering the surface sliding of the gear tooth, lubricating oil condition and load.The lubrication mechanism of the meshing tooth modbiv surface is analyzed, and the sliding frict
Extreme, tsunami-like wave runup events in the absence of earthquakes or landslides have been attributed to trapped waves over shallow bathymetry, long waves created by atmospheric disturbances, and long waves generated by abrupt breaking.These runup events are associated with inland excursions of hundreds of meters and periods of minutes.While the
This contribution discusses the integration processes of immigrants and minorities with a recent immigrant background, and the policies related to the process of settlement of these newcomers in European societies at all relevant levels: from the local level of municipalities and cities, to the national level of states, and the international level
The recognition and elimination of invading pathogens are vital for host survival.Macrophages play a central role in host protection and cells functionally reminiscent of vertebrate macrophages are present in all multicellular organisms.A pattern responsible for bacterial recognition found on the surface of macrophages is CD14.These cells possess a
