Spinal stenosis is the narrowing of spaces in the spine (backbone) which causes pressure on the spinal cord and nerves. About 75% of cases of spinal stenosis occur in the low back (lumbar spine).
Both static and dynamic measurements can be taken. Static coefficient of friction (SCOF) is the frictional. resistance one pushes against when starting in motion. Dynamic coefficient of friction (DCOF) is the frictional resis-. tance one pushes against when already in motion. For SCOF and DCOF, a slip occurs when pushing off with more.
Dichloromethane (DCM, or methylene chloride) is an organic compound with the formula C H 2 Cl 2.This colorless, volatile liquid with a moderately sweet aroma is widely used as a solvent. Although it is not miscible with water, it is miscible with many organic solvents.CM's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. It is widely used as a paint stripper and a degreaser. In the food industry, it has been used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavorings.
