Mechanics of sliding in rate/state friction experiments
2006One difficulty that arises in the application of rate-state experimental results to natural events is the problem of scale: the size of samples is measured in centimeters whereas faults are many kilometers in length and depth, and the disparity in the scales of time is as great. The research reported here is designed to bridge this gap.

A note on the rate sensitivity of frictional sliding of westerly granite
Journal of Geophysical Research: Solid Earth, 1984The frictional sliding of simulated faults containing crushed Westerly granite was studied in a series of constant stepped velocity experiments. Confining pressures were varied from 0.00733 to 7.33 μm/s. The strain rate sensitivity B, that is, the slope of the frictional stress change Δμ with the logarithm of the change in velocity, (log10 (V2/V1 ...

The effect of sliding speed on the rate of wear of sapphire on steel
Wear, 1966Abstract Frictional force in the sapphire-steel slide interface is reduced with increased sliding speeds. The high temperatures generated at the higher sliding speeds appear to promote chemical reactions, the products of which serve to decrease the shear forces in the interface.

Effect of Heating Rate in Low Speed Sliding Experiments
Nature Physical Science, 1971BLOK'S critical temperature hypothesis1 is widely used in estimating the temperature at which gear teeth will scuff when lubricated by plain mineral oils. Low speed sliding experiments have been used by several workers to test the hypothesis because of the insignificant frictional heating afforded by this technique and hence the fact that bulk ...

Diagnostic Rate of the Cancer by BDORT Utilizing the Cancer Slide
Acupuncture & Electro-Therapeutics Research, 1999Purpose: To make a diagnosis of cancer with BDORT (resonance test), we can choose two methods. One is to use a chemical agent like Integrin α5β1 or Oncogene C-fos Ab2, the other is to use microscopic cancer slides. These two methods were originally introduced by Prof. Omura of New York.

The ratings slide. Are we headed for a capital crisis?
Hospitals & health networks, 1999On hospital credit ratings, the news is tough and tougher--what many industry watchers call a capital crisis in the making. Rating agencies contend the situation has been building for years, even while hospital margins reached historic highs as recently as 1997. "Then everything fell apart at the seams," says one bond rating pro.
