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.
XLIF may be recommended to treat the following lumbar or lower spine disorders: 1  Adjacent level syndrome, a condition that develops adjacent to the site of a previous fusion surgery. 2  Degenerative disc disease with instability. 3  Degenerative scoliosis, a right or left curvature of the spine.
