I recently conducted my own cost-per-RVU analysis for the radiology department at Wadsworth Rittman Hospital, an acute care facility licensed for 113 beds. The radiology department performs more than 40,000 procedures per year, which ought to be manageable.
What Are the Four Causes of Mechanical Weathering? By Wayne Shirey; Updated April 24, 2017 The process of weathering breaks down rocks exposed to the elements into smaller particles that can be carried away by wind and water erosion. Weathering is divided into three broad categories: mechanical or physical weathering, chemical weathering, and biological weathering. Mechanical or physical weathering is further divided by its causes into four different categories; the causes are mechanical exfoliation or unloading, thermal expansion, frost wedging, and abrasion.
Spheroidal weathering is a form of chemical weathering that affects jointed bedrock and results in the formation of concentric or spherical layers of highly decayed rock within weathered bedrock that is known as saprolite.pheroidal weathering is the result of chemical weathering of systematically jointed, massive rocks, including granite, dolerite, basalt and sedimentary rocks such as silicified sandstone. It occurs as the result of the chemical alteration of such rocks along intersecting joints.
