Heart Failure: Biomarkers of Diagnosis and Prognosis

The natriuretic peptides (NP), including the precursor N-terminal proBNP (NT-pro-BNP) of biologically active B-type natriuretic peptide (BNP) represent the current standard for identifying Heart Failure. In addition, the troponins serve to help identify Heart Failure patients at high risk for adverse outcomes. For nearly the last decade, emergency physicians have used these biomarkers to diagno...

Experiment of Ultimate Shear Failure and Friction Sliding Performance of Rubber Bearings of Bridges

The results showed that (1) the ultimate shear deformation of the rubber bearings with two fixed end plates reached 300% to 400% of the rubber layer thickness. The damage was mainly focused on the rubber layer fracture. The energy dissipation capacity of the bearings was weak, and the hysteresis curve presented a narrow zonal shape. (2) The rubber bearings with unilateral friction sliding had a...

Lubrication of Sliding Bearings for Hydropower Applications

The influence of pad facing material on hydrodynamic lubrication in tilting-pad thrustbearings is investigated in terms of pad and oil-film temperatures and oil-film thickness. Two tilting-pad thrust bearings are examined: one with babbitt pad facing, the other with a layer of a PTFE based composite material. Frictional torque, pad, collar and oil-film temperatures and oil-film thicknes...
