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.
First of all, what is DCF? Itâs an unofficial term for Direct Consular Filing, which is when a US citizen files an I-130 Petition for Alien Relative (in our case, my spouse), at a Consulate or USCIS Field Office overseas, rather than at a US Service Center.
