Interfacial Convection

The interfacial behaviour of two unstable binary liquid-liquid systems was investigated under normal gravitational conditions and under the microgravity conditions achieved in the NASA KC-135 parabolic flights to decouple gravitational instabilities from Marangoni instabilities. Results indicate that under normal gravitational conditions interfacial convection was observed in both systems. Under microgravity thermal Marangoni disturbances were strong enough to produce interfacial instabilities in one of the systems. Results are interpreted in terms of interactions between Marangoni and gravitational instabilities.

Intubation Procedure

Background Training of National Aeronautics and Space Administration space shuttle astronauts revealed difficult airway management with endotracheal tubes (ETTs) under microgravity conditions. The authors performed a randomized comparative study of ETT and Combitube (ETC; Tyco Healthcare, Pleasanton, CA). The aim of the study was to evaluate ease, time of insertion, and success rates during normogravity and parabolic flights using mannequins. Methods After normogravity experiments, four flyers performed intubation on a mannequin during the flights. Sixty-two intubation attempts were performed using the ETC (normogravity, 29; microgravity, 33), and 58 intubation attempts were performed using the ETT (each 29 attempts, both conditions). Time to completion of the intubation procedure, success rate, and ease of insertion were recorded. Results The ETC performed equally well between normogravity (median, 18 s; range, 17-25 s) and microgravity (median, 18.5 s; range, 17-28 s), whereas the ETT performed significantly slower under microgravity (median, 20 s; range, 17-27 s) as compared with normogravity (median, 18 s; range, 16-22 s; P = 0.019). One hundred nine of 120 (90%) were successful. The ETT and ETC were comparable with respect to successful intubations, under normogravity or microgravity, respectively. Conclusions Both the ETC and ETT perform comparably well. Slight differences could be found with respect to time of insertion in favor of the ETC. Because this is the first experiment using the ETC on the KC-135, it is shown that there is enough time to perform the insertion procedure. Because the ETC airway requires less training and is easier to insert than an ETT, it is recommended for further study as an alternative airway to what is currently on the shuttle.

Growth Experiments

The II-VI semiconducting alloys, such as mercury zinc telluride (MZT), have become the materials of choice for numerous infrared detection applications. However, compositional inhomogeneities and crystallographic imperfections adversly affect the performance of MZT infrared detectors. One source of imperfections in MZT is gravity-induced convection during directional solidification. Crystal growth experiments conducted in space should minimize gravity-induced convection and thereby the density of related crystallographic defects. The limited amount of time available during Space Shuttle experiments and the need for a sample of uniform composition requires the elimination of the initial composition transient which occurs in directionally solidified alloys. One method of eluding this initial transient involves directionally solidifying a portion of the sample and then quenching the remainder prior to the space experiment. During the space experiment, the MZT sample is back-melted to exactly the point at which directional solidification was stopped on earth. The directional solidification process then continues.
