For the purpose of this article, I will be referring to the conversion of existing buildings of a different use to self-storage. These buildings may include retail stores, office buildings, schools, hotels, industrial buildings, and miscellaneous properties such as abandoned bus stations, underground parking lots, etc.
Bioassays: Background Information. A bioassay involves use of a biological organism to test for chemical toxicity. Perhaps the oldest and most commonly known example is the canary in the coal mine. Traditionally, coal miners have taken caged canaries down into the mines to help ensure a safe air supply.
Dual X-ray absorptiometry (DXA) is the preferred technique for measuring bone mineral density (BMD). DXA has also been called dual energy X-ray absorptiometry, or DEXA.DXA is relatively easy to perform and the amount of radiation exposure is low.A DXA scanner is a machine that produces two X-ray beams, each with different energy levels.One beam is high energy while the other is low energy.ual X-ray absorptiometry (DXA) is the preferred technique for measuring bone mineral density (BMD).
