Local loss of the outer layer (epithelium) of the cornea, so that the sensory nerves are exposed to stimulation by movement of the lids. This may be exquisitely painful. The epithelium usually regrows in a day or two. Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005 corne...
Abrasive wear: defined as the displacement or loss of material from a surface due to hard particles (or protuberances) forced along and moving against a solid surface. From:The Cold Spray Materials Deposition Process,2007 Discover other topics ...
Metal loss caused by abrasion and/or erosion at critical points in the pump stage or in its different bearings (radial and axial), even if other components of the pump are not attacked, may lead to the catastrophic failure of the pump. In the following, sand problems and their solutions ...
Note, that both (1) and (2) are formulated in terms of the speed in the inward normal direction, meaning that they incorporate both the normal vector and the curvature. As a result, the equations contain a nonlinear function of the first and second partial derivatives of the curve. The ...
The average volume loss is consistent between rounded and angular pebbles at any time (59.3% and 64.2% after 13 months respectively), meaning that the roundness is not a primary control factor on abrasion rate. The pebbles that did not reach such abrasion rates after 8 and 10 months (volume...
By electrostatic adsorption, the microcapsules are embedded in MWCNT (as both the enhancer and conductive filler), which could partially bear the friction stress to protect the microcapsules from loss during the abrasion test. Therefore, the modified microcapsule/MWCNT coated wood could obtain good ...
In addition, the state of the fabric surface was determined by frequency spectra in which the peak heights had the same tendency as fabric roughness, meaning a dependence on global structure and hairiness. A second device had been developed [3] in order to measure the hairiness quantity on ...
The change in tool hardness will shift the inverted S-curve, meaning that the absolute value of relative hardness is not the determining factor for wear. Furthermore, the behavior of the tribological system and wear of tools in various soil mixtures will change with the presence of water.;...
The emphasis in the disclosure of the Scher et al U.S. Pat. No. 4,255,480 is on the economic advantages achieved by eliminating overlay, and it is pointed out at column 3 of this patent that the elimination of overlay saves raw material and avoids product loss attributable to handling ...
is a labor intensive and expensive process. Furthermore is such a covered yarn less robust during use and shows shift or integrity loss of the helical wrapping leading to heterogeneous appearance yarns and handling difficulties resulting in a loss of production or a reduced quality of the fabrics...
