Physical Review E, 2011
A model for the collision between a sand grain and a body of yardang material is established by using the principles of classical mechanics. A new nondimensional parameter, the "abrasion number" A(n), is derived from the model. The volume removed per impact for different targets is proportional to A(n) approximately. As an indicator of the energy ratio

SummaryCertain diseases of the nail complex cause hyperkeratosis or alterations of the shape of the nail plate. These conditions may be painful, may decrease the penetration of topical medicaments and may be ugly. The nail plate abrasion, performed with dermabrader device or sandpaper, has application in patients suffering from onychomycosis, psoriasis,

Cost calculation for recycled abrasives and for abrasive selecting in abrasive waterjet machining
International Journal of Precision Technology, 2007This paper introduces a new study on the calculation of the cost of recycled abrasives and the total cost when cutting with new and recycled abrasives in Abrasive Waterjet (AWJ) machining. In this study, many cost components such as machine cost, labour cost, power cost and so on were taken into account both for calculation of the recycled abrasive ...

A MECHANISM OF CORNEAL ABRASION*
Optometry and Vision Science, 1970ABSTRACT A patient overwore her contact lenses intentionally until an abrasion occurred so that the experimenter could study the tissue changes. On the basis of the observations, an hypothesis for the cause of abrasion is suggested, and several precautionary measures for avoiding abrasions are
