Novel Optical Technique Developed and Tested for Measuring Two-Point Velocity Correlations in Turbulent Flows

A novel technique for characterizing turbulent flows was developed and tested at the NASA Glenn Research Center. The work is being done in collaboration with the University of Pittsburgh, through a grant from the NASA Microgravity Fluid Physics Program. The technique we are using, Homodyne Correlation Spectroscopy (HCS), is a laser-light-scattering technique that measures the Doppler frequency shift of light scattered from microscopic particles in the fluid flow. Whereas Laser Doppler Velocimetry gives a local (single-point) measurement of the fluid velocity, the HCS technique measures correlations between fluid velocities at two separate points in the flow at the same instant of time. Velocity correlations in the flow field are of fundamental interest to turbulence researchers and are of practical importance in many engineering applications, such as aeronautics

Executive Summary: Diagnosis and Management of Prosthetic Joint Infection: Clinical Practice Guidelines by the Infectious Diseases Society of Americaa

These guidelines are intended for use by infectious disease specialists, orthopedists, and other healthcare professionals who care for patients with prosthetic joint infection (PJI). They include evidence-based and opinion-based recommendations for the diagnosis and management of patients with PJI treated with debridement and retention of the prosthesis, resection arthroplasty with or without subsequent staged reimplantation, 1-stage reimplantation, and amputatio

Ezekiel and the Covenant of Friendship

The slippery idea of "spirituality" might, with care, be put to use by biblical exegetes. Spirituality is defined in this paper as the social enactment of religious ideas. Four categories are offered to analyze the biblical witness as a record of spirituality. These categories are, first, an ultimate end; second, an ideal self-image by which this end might be achieved; third, an encoding of teachings in Scripture by which the self-image can be realized or understood; and fourth, a proposal for a way of life that makes achievement of the ultimate end a practical possibility. Accordingly, Ezekiel's "spirituality" may be understood to have, on one hand, an ultimate end of a return of the people to the land with the presence of God; and on the other, an ideal self-image of conversion of the community toward this ultimate end. Then it encodes, in oracles of judgment and deliverance, teachings that enable adherents to form the ideal self-image, and finally, as a way of life that puts these teachings into practice, it proposes a "covenant of friendship" (Ezek 34:25 and 37:36) among the exiled people and between them and their captors.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66911/2/10.1177_014610799202200402.pd
