More than 1,000 industrial amputees at the Ontario Workers' Compensation Board were reviewed. The study investigated the current employment status of amputees and the factors that influenced successful return to work post-amputation. The data obtained from a mailed questionnaire was analysed by the Statistical Analysis System. The results revealed that 89% of amputees returned to work after an ...

Multiple loop heat pipes which have two evaporators and two condensers in one loop are a kind of active heat transfer device. Since they have two evaporators and two condensers, the operating mode also becomes multiple. This work discusses the cases that multiple loop heat pipes were operated with one condenser at high temperature and the other at low temperature. To avoid the high temperature ...

one of the most common methods for controlling and increasing maneuverability of projectiles, especially the ones which move at high altitude and in low density air, is using lateral or reaction jets. the resultant force of the reaction jet is related to the jet and flow parameters. for finding their relation experimental, numerical, and analytical methods have been used. in order to change the...

CONTEXT A recently updated meta-analysis of return-to-sport rates after anterior cruciate ligament (ACL) reconstruction demonstrated that 65% of athletes returned to their preinjury level of sport after surgery. The aim of this clinical review was to explore contextual factors associated with returning or not returning to the preinjury level after ACL reconstruction. EVIDENCE ACQUISITION Data...

A field experiment with six treatments was conducted to study the nitrogen reserves in summer maize topsoil on the north China plain. Results showed that topdressing significantly increased topsoil nitrogen reserves. Summer corn topsoil nitrogen reserves were affected by several management measures. Shallow tillage, wheat straw no-returning and deep intertillage at the corn seedling stage signi...
