“Separating bulk solids via air classification, screening or gravity separation is ubiquitous in many industries — an understanding of these processes is crucial to solids-handling engineers” The chemical process industries (CPI) have many applications that [,]
Osteoporosis: Innovations in Screening and Diagnostics There is currently only one method used routinely to screen for osteoporosis, the DEXA test (short for dual-energy x-ray absorptiometry) The DEXA test attempts to predict which women are at risk of fracture based on an assessment of their density
