The Spurling's test was 95% sensitive and 94% specific for diagnosing nerve root pathology. [2] In another study done in the late 1900s, 255 patients were examined using a Spurling test and afterwards received an electrodiagnostic examination. The study results showed the Spurling test was 30% sensitive, and 93% specific for finding cervical ...

Normal values (95% confidence intervals) are approximately 30-60% CD4 and 10-30% CD8 depending on age (ratio 0.9 to 3.7 in adults). [1] One reason for abnormal results is the loss of CD4-positive cells to the human immunodeficiency virus (HIV) infection. The loss of CD4-positive cells to HIV infection can result in various distortions in the ...
Compression test for steel drum. The container compression test measures the compressive strength of packages such as boxes, drums, and cans. It usually provides a plot of deformation vs compressive force. It is commonly used to evaluate shipping containers made of corrugated fiberboard as well as wooden boxes and crates.
Compression set A is defined as the percentage of original specimen thickness after the specimen has been left in normal (uncompressed) conditions for 30 minutes. C A, the compression set A is given by C A = [(t o - t i) / t o] * 100 where t o is the original specimen thickness and t i is the specimen thickness after testing. [2]
For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.

A diametral compression test involves applying a stress load or force to the point where a material object is split in half (down the diameter of the object). [1] This test indirectly measures the tensile property of a material object, as the molecules of the material are pushed apart in opposite directions, similar to what happens to molecules in a direct tensile strength test.
