Attrition (abrasion), fluvial. Fluvial attrition is generally understood to refer to any process of mechanical grain wear leading to grain size reduction in the course of sediment transport through rivers. Fluvial abrasion is generally accepted as an equivalent term, though it might also be interpreted to mean modification of the stream bed or ...

Quartz exhibits a number of striking physical properties that contribute to its utility and aesthetic appeal. It is a hard, crystalline mineral, scoring a 7 on the Mohs hardness scale. This hardness, along with its lack of cleavage, makes quartz resistant to weathering and erosion. Furthermore, quartz is also characterized by its hexagonal ...

These studies have addressed this possibility by investigating the effect of the amount of L1 contact on the attrition process. Nonetheless, as with L2 effects, the corresponding evidence is quite inconsistent and, importantly, tends to point toward the interrelation of factors related to both L1 and L2 as responsible for attrition (De Bot, 2002).

It's about employees leaving and needing to be replaced quickly through rehiring. The average attrition rate can vary depending on factors like industry, region, and company size. According to a study by Mercer, the global average voluntary attrition rate was around 11.1% in 2021, a 1.2% increase from 9.9% in 2020.

Theory. v. t. e. A war of attrition is a military strategy in which one side tries to cause the other to lose so many soldiers and to have so much military equipment destroyed that the enemy forces are worn down until they collapse. [1] The side that has more resources (soldiers and military equipment) usually wins.
