Nutritional status assessment in semiclosed environments: ground-based and space flight studies in humans.
Adequate nutrition is critical during long-term spaceflight, as is the ability to easily monitor dietary intake. A comprehensive nutritional status assessment profile was designed for use before, during and after flight. It included assessment of both dietary intake and biochemical markers of nutritional status. A spaceflight food-frequency questionnaire (FFQ) was developed to evaluate intake o...
متن کاملNew concepts for Space-Based and Ground-Based Laser Weapons
Is the Department of Defense (DOD) pursuing the correct investment strategy for space-based laser weapons? Recent advances in lasers, optics, and spacecraft technologies may bring high-energy laser weapons to a sufficient level of maturity for serious consideration as space weapons against the theater ballistic missile threat. However, these technological advances also make other architectures ...
متن کاملGround-based Telerobotic Interfaces for Space Telescience
So far, Earth-based space science has been carried out from a few dedicated facilities, with scientists working away from their home institution and with limited participation of the science community to the experiments. A better approach to ground control of space experiments would consist of deploying a network of operation stations located at various institutions and connected via Internet t...
متن کاملHelioseismology and Solar Abundances
Helioseismology has allowed us to study the structure of the Sun in unprecedented detail. One of the triumphs of the theory of stellar evolution was that helioseismic studies had shown that the structure of solar models is very similar to that of the Sun. However, this agreement has been spoiled by recent revisions of the solar heavy-element abundances. Heavy element abundances determine the op...
متن کاملHelioseismology Present and Future
The subject of helioseismology is in a exciting phase of expansion. in terms of the methods being developed and applied, the new and challenging results coming out from the high-quality data that present observational campaigns, networks and missions are providing, the arrival of GONG+, the prospects for new missions including Solar Dynamics Observatory, and the recent groundbased results and e...
