The research is aimed at improving the quality of testing tribotechnical characteristics materials on SMT-1 friction machine. Testing bearing according to disc-pad model may be incorrect due sample runouts. aim this work was level out influence runouts wear and other units.

AIM During lower limb immobilization, patients are at risk to develop deep venous thrombosis. Recently, a water-pad was developed that should counteract venous stasis. The water-pad, located under the plaster, mobilizes water from the foot to the calf during weight bearing and, thereby, imitates muscle pump function. The purpose of this study was to assess the effect of the water-pad on venous ...

Widely used in turbomachinery, the fluid film journal bearing is critical to a machine’s overall reliability level. Their design complexity and application severity continue to increase making it challenging for the plant machinery engineer to evaluate their reliability. This tutorial provides practical knowledge on their basic operation and what physical effects should be included in modeling ...

High heat generation in the hydrodynamic wedge is one of main factors limiting application pad journal bearings as for rotors aircraft gas turbine engines. The goal research to study influence oil supply method on bearing thermal state and determine design reducing temperature. was carried out with use diameters 100320 mm different supply: through dispensing grooves pads, nozzles inter-pad spac...

The use of xenografts and allografts has been primarily direct- ed at chronic wounds and tendon repair. Currently, there are no known devices in this category that can successfully be used to augment tis- sue. Patients who have undergone trauma and subsequent surgery, par- ticularly in weight-bearing areas, may experience pain with pressure or ambulation at the site. This report illustrates the...
