Effects of Cushing Disease on Bone Mineral Density in a

Cushing disease is rare in children ().Osteopenia has been reported in adults with Cushing disease (27).Although exposure to excess glucocorticoids is a frequent cause of osteoporosis or osteopenia in both children and adults, limited data are available about bone mineral density (BMD) in children with Cushing disease (712).It is known that hypercortisolism is associated with loss of

Ore, Rock & Aggregate Screening (Complete Guide)

Effect of material humidity on screening. Humidity has the greatest effect on the screening of fine material when the hole size is approx. 16 mm or smaller. The effect gets smaller with larger hole sizes. Due to the surface tension of water the finest particles adher to the surface of the larger particles and are carried to the wrong fractions.

DEM analysis of the effect of granular crushing on the

AbstractGranular materials underneath footings are subjected to static and dynamic loads. As a result of these loads particle crushing may occur depending on the strength of the soil particles. Since particle crushing reduces the shear strength of a granular material and produces settlements, the performance of an engineering structure supported on a crushable soil can be compromised due to

Factors Affecting Density of Matter by Ron Kurtus

Apr 05, 2014 · The volume of a material can change with temperature and pressure. This, in turn, changes the density of the material. Density and temperature. As the temperature increases, most materials expand or increase their volume. This results in a decrease in density. Likewise, when the temperature goes down, the density usually becomes greater.
