To decide whether the same method can be used to measure the specific heat capacity of a sample, the following factors that affect measurement during thermal diffusivity tests need to be analyzed: 1  Rise in temperature. 2  Laser pulse magnitude. 3  Reflection by other media. 4  Sample-related problems.
Extreme Lateral Interbody Fusion (XLIF) Extreme lateral interbody fusion (XLIF) is a minimally invasive procedure performed through the side of the body to treat spinal disorders and reduce long-term back or leg pain that has not responded to other treatments, such as steroid injections, physical therapy and pain medication.
Despite its advantages, your physician may decide that the XLIF procedure is not the most appropriate approach for you. The XLIF procedure is not recommended for the following patients: 1  Those suffering from symptoms in the L5 âS1 level of the spine. 2  Those with certain lumbar deformities. 3  Those with severe degenerative spondylolisthesis (significant slip of one vertebrae over another).
