Integrated gas analyzer for complete monitoring of turbine engine test cells.

Fourier transform infrared (FT-IR) spectroscopy is proving to be reliable and economical for the quantification of many gas-phase species during testing and development of gas turbine engines in ground-based facilities such as sea-level test cells and altitude test cells. FT-IR measurement applications include engine-generated exhaust gases, facility air provided as input to engines, and ambient air in and around test cells. Potentially, the traditionally used assembly of many gas-specific single gas analyzers will be eliminated.

Factors prolonging disability in work-related cumulative trauma disorders.

Workers' compensation costs for management of soft tissue disorders continue to increase. The complexity of medical management of these cases has increased due to social factors. The purpose of this study is to improve the physician's ability to recognize nonmedical issues that prevent a rapid return to employment.
