Methods of assessing erosion and erosive potential
European Journal of Oral Sciences, 1996Methods for use in vitro are reviewed first, classified under the examination of extracted teeth, chemical and physical methods, digital image analysis, scanning electron microscopy and other potentially useful techniques. Methods for recording erosion in laboratory animals are dealt with next, including techniques that can also be used in vitro ...

Erosion and Erosion-Corrosion of Metals
Corrosion, 1995The loss of material from the surface of a metal being impacted by small, solid particles carried in a flowing gas occurs by a sequence of mechanical actions.The present work, which was presented as the plenary lecture at CORROSION/95, describes the mechanisms that occur on ductile and brittle materials and relates these mechanisms to surface loss ...

Erosion and Erosion Protection
2010One of the greatest challenges in the use of infrared windows and domes is to protect them from damage by particle impact. Collisions with raindrops are a problem at the velocities of airplanes and missiles. Figure 7.1 shows the damage to a missile dome after traversing a rainfield on the rocket sled in Fig. 7.2.

All tooth surfaces exposed to the oral environment are naturally coated by the acquired salivary pellicle. The pellicle is composed of adsorbed macromolecular components from saliva, gingival crevicular fluid, blood, bacteria, mucosa and diet. The pellicle (formed in situ/in vivo) functions as a semipermeable network of adsorbed salivary macromolecules

Abstract This chapter discusses the erosion and erosion-corrosion behaviors of metals and alloys. It includes data primarily related to particle-laden gas streams impacting on the metal surface. It also covers properties and applications and provides guidelines for materials selection.

Seminars in Musculoskeletal Radiology, 2003
Erosive osteoarthritis (EOA) is a progressive disorder affecting the interphalangeal joints of the hands. Severe synovitis is superimposed on the typical changes seen in conventional interphalangeal osteoarthritis (OA), which includes formation of Heberden's and Bouchard's nodes. Imaging studies show a combination of bony proliferation (osteophytosis),

Erosion of Geomaterials - Internal erosion and surface erosion
2012This compendium aims to deliver a significant part of the current French scientific progress on the problem of the erosion of geomaterials, with a focus on the mechanical/physical aspect. The contributions oscillate between a phenomenological outlook that is well grounded in experiments, and an approach that can offer a modeling framework.

Veterinary Record, 2014
I HAVE recently had the pleasure and privilege of working at the AHVLA Penrith regional laboratory. This confirmed my already high opinion of the vets in the labs, but also made me appreciate the high professional standards of the rest of the staff who perform many of the highly demanding and complex tests.

Wind erosion climatic erosivity
Climatic Change, 1986A physically based wind-erosion climatic factor has been derived: $$CE = \rho \int {[u^2 } - (u_T^2 + \gamma ^l /\rho a^2 )]^{3/2} f(u)du$$ where ϱ is the air density, a is a constant made up of other constants (von Karman, height of wind speed observation ...
