Product Description
Chilldown process is a complicated process involves unsteady two-phase heat and mass transfer and initiates the cryogenic fluids transport. To advance the understanding of this process, both experimental and modeling investigations have been carried. The chilldown process can be generally divided into three regions which are associated with different flow regimes and heat transfer mechanisms. Under low flow conditions, the two-phase flow during chilldown is dispersed. The statistic feature of the liquid filaments is studied and a model, in which the heat transfer at the bottom is considered as a sum of vapor and liquid components, has been developed for the dispersed flow film boiling. The bottom wall heat flux is found to decrease under microgravity condition. A cryogenic chilldown model has also been developed. The model focuses on both vertical tube orientation and microgravity chilldown and shows a good agreement with previous experimental data. ... Read more

Product Description
For thirty years, the NASA microgravity program has used space as a tool to study fundamental flow phenomena that are important to fields ranging from combustion science to biotechnology. This book assesses the past impact and current status of microgravity research programs in combustion, fluid dynamics, fundamental physics, and materials science and gives recommendations for promising topics of future research in each discipline. Guidance is given for setting priorities across disciplines by assessing each recommended topic in terms of the probability of its success and the magnitude of its potential impact on scientific knowledge and understanding; terrestrial applications and industry technology needs; and NASA technology needs. At NASA's request, the book also contains an examination of emerging research fields such as nanotechnology and biophysics, and makes recommendations regarding topics that might be suitable for integration into NASA's microgravity program. ...

Product Description
Increased funding for ground-based research by national space agencies coupled with the development of unique hardware for experimentation in space has led to a tremendous increase in research into the behaviour of materials under microgravity conditions. The thirty-three papers in this volume highlight research areas of particular scientific and industrial interest and discuss specific ground-based projects where the results of laboratory research are applied by industry to the development of flight hardware. ...

Product Description
For the first time in the history of mankind, space technology enables researchers to escape the gravitational field of the Earth and to investigate physical phenomena in an environment of near weightlessness. Consequently, the space environment is of enormous interest to the scientific community as a new media in which to investigate the effects of the lack of gravity on numerous processes, especially those involving the transport of heat and matter in fluids. Flight opportunities are scarce so it is important that the international scientific community and space agencies coordinate their scientific activities in addition to the development of facilities and space platforms. Because of the limited opportunities to experiment in orbit, theoretical and numerical evaluations of the influence of gravity on physical phenomena are increasingly employed. The 53 papers contained in this volume represent the most up to date results in microgravity and prepare the ground for meaningful utilisation of the forthcoming International Space Station "Freedom". ...

Product Description
The ability of a cholesterol-reducing drug, simvastatin, to stimulate the formation of hydroxyapatite in an osteoblast-like cell line, was studied using Fourier transform infrared spectroscopy. Hydroxyapatite was detected using both Fourier transform infrared spectroscopy and von Kossa staining techniques a week earlier when cells were cultured in growth media supplemented with simvastatin in a tissue culture polystyrene system. Analysis of infrared spectra using area integration and curve-fitting techniques was performed to quantify the hydroxyapatite content in cells relative to the biological matrix. Infrared spectroscopy was used to quantify the mineralization process. Cells grown in a rotating bioreactor mineralized more rapidly than cells grown in tissue culture polystyrene systems. ...
