Assessment of movements of joints is an important part of their clinical examination. However, movements of the spine are particularly difficult to measure because of its inaccessibility. Normally X-ray measurements are complicated by magnification and distortion, and are restricted to two dimensions. This paper describes the application of the technique of(More)
This work is a review of the mechanical factors related to low back pain production in a vibration environment. The sitting posture is an extreme orientation for the lumbar intervertebral disc that 1) increases its internal pressure, 2) increases its anteroposterior shear flexibility, while: 3) decreasing its resistance to buckling instability and 4)(More)
ion, as used in the context of the analysis described in the THC Abstraction AMR (CRWMS M&O 2000c), refers to an extraction of essential data or information from the process level model. The abstraction analysis reproduces and bounds the results of the underlying detailed process-level model. The DS THC process model developed in the THC Process AMR (CRWMS(More)
Mapping of geologic discontinuities has been done in several phases at the Spent Fuel Test—Climax (SFT-C) in the granitic Climax stock at the Nevada Test Site. Mapping was carried out in the tail drift, access drift, canister drift, heater drifts, instrumentation alcove, and receiving room. The fractures mapped as intersecting a horizontal datum in the(More)
