Relative importance of body composition, osteoporosis-related behaviors, and parental income on bone speed of sound in adolescent females

Abstract Mixing characteristics of supercritical injection studies were analyzed with regard to the necessity to include diffusive fluxes. Therefore, speed of sound data from mixing jets were investigated using an adiabatic mixing model and compared to an analytic solution. In this work, we show that the generalized application of the adiabatic mixing model may become inappropriate for subsonic submerged jets at high-pressure conditions. Two cases are discussed where thermal and concentration driven fluxes are seen to have significant influence. To which extent the adiabatic mixing model is valid depends on the relative importance of local diffusive fluxes, namely Fourier, Fick and Dufour diffusion. This is inter alia influenced by different time and length scales. The experimental data from a high-pressure n-hexane/nitrogen jet injection were investigated numerically. Finally, based on recent numerical findings, the plausibility of different thermodynamic mixing models for binary mixtures under high pressure conditions is analyzed.

Bod Pod

AbstractThe feasibility and acceptability of using the Bod Pod procedure to measure changes in body composition in 30 adolescent females admitted to an inpatient eating disorder unit was evaluated using written surveys, Bod Pod measurements obtained at admission and discharge, and medical records review. Participants rated the Bod Pod test as acceptable (100%; 30/30), comfortable (93%, 28/30), and they were willing to repeat the procedure (97%, 29/30). Ten participants did not complete the final Bod Pod: eight were discharged before a second measure could be obtained, one refused the test, and one left against medical advice. Three participants had undetectable readings at admission. Paired t-tests (n = 17) revealed a significant (p < 0.001) mean increase in fat mass (3.7 ± 2 kg), body fat percentage (6.6 ± 3.8%), and lean mass (1.4 ± 1.2 kg) from admission to discharge. The Bod Pod is a feasible and acceptable procedure to measure changes in body composition in adolescent females hospitalized with an eating disorder.
