Influence of Feed Motion on Surface Friction of AISI 1045 Steel Machined by a Fine-Grinding Process
Tribology in Industry, 2021 Fine-grinding is a final machining method used to reach the low friction and high-quality surface. The workspeed (vw) and crossfeed (vc) motions are perpendicular to each other and differ in value during the grinding process. Thus, the surface quality in

Influence of Humid Air Temperature on Friction Behavior in Pneumatic Cylinder
Tribology in Industry, 2021 In the air, water vapor always exists and impacts directly on the friction surface between the piston rod and the rod seal. Water vapor in the air forms moisture film on the surface of the piston rod. In some cases, it plays a role as a lubricant.

Maintaining proteostasis under mechanical stress [PDF]
EMBO reports, 2021 Cell survival, tissue integrity and organismal health depend on the ability to maintain functional protein networks even under conditions that threaten protein integrity. Protection against such stress conditions involves the adaptation of folding and degradation machineries, which help to preserve the protein network by facilitating the refolding or ...

Can the Biophilia Hypothesis Be Applied to Long-Duration Human Space Flight? A Mini-Review
Frontiers in Psychology, 2021 The International Space Station (ISS) has around 3–5 crew members on-board at all times, and they normally stay on the ISS for about 5–7months in duration. Since March 2020, 170 long-duration space missions have occurred on the ISS.
