National Space Development Agency of Japan (NASDA) has developed aquatic animal experiment facilities for NASA Space Shuttle use. Vestibular Function Experiment Unit (VFEU) was firstly designed and developed for physiological research using carp in Spacelab-J (SL-J, STS-47) mission. It was modified as Aquatic Animal Experiment Unit (AAEU) to accommodate small aquatic animals, such as medaka and newt, for second International Microgravity Laboratory (IML-2, STS-65) mission. Then, VFEU was improved to accommodate marine fish and to perform neurobiological experiment for Neurolab (STS-90) and STS-95 missions. We have also developed and used water purification system which was adapted to each facility. Based on these experiences of Space Shuttle missions, we are studying to develop advanced aquatic animal experiment facility for both Space Shuttle and International Space Station (ISS). 相似文献

By applying the cross-phase method and the amplitude-ratio method to magnetic field data obtained from two ground stations located close to each other, we can determine the frequency of the field line resonance (FLR), or the field line eigenfrequency, for the field line running through the midpoint of the two stations. From thus identified FLR frequency we can estimate the equatorial plasma mass density (ρ) by using the T05s magnetospheric field model [Tsyganenko, N.A., Sitnov, M.I. Modeling the dynamics of the inner magnetosphere during strong geomagnetic storms, J. Geophys. Res. 110, A03208, 2005] and the equation of Singer et al. [Singer, H.J., Southwood, D.J., Walker, R.J., Kivelson, M.G. Alfven wave resonances in a realistic magnetospheric magnetic field geometry, J. Geophys. Res. 86 (A6) 4589–4596, 1981]. 相似文献

The National Space Development Agency of Japan (NASDA) has more than 20 years of experience developing aquatic animal experiment facilities. We are now studying the next-generation aquatic animal experiment facility or the Aquatic Habitat (AQH) for both Space Shuttle and International Space Station use. A prototype breeding system was designed and tested. Medaka adult fish were able to mate and spawn in this closed circulatory breeding system, and the larvae grew to adult fish and spawned on the 45th day after hatching. The water quality-control system using nitrifying bacteria worked well throughout the medaka breeding test. For amphibians, we also conducted the African clawed toad (Xenopus laevis) breeding test with the same specimen chambers, although a part of circulation loop was opened to air. Xenopus larvae grew and completed metamorphosis successfully in the small specimen chamber. The first metamorphic climax started on the 30th day and was completed on the 38th day. 相似文献

The mean sea-surface height obtained from satellite altimeters is different from the geoid by the amount of mean sea-surface
dynamic topography associated with ocean currents. Assuming geostrophy at the sea surface, the mean sea-surface dynamic topography
can be obtained from the mean sea-surface velocity field. This field is derived by combining anomalies (i.e., deviations from
the mean) of sea-surface velocity obtained from altimeter data and in situ surface velocities estimated from trajectories of surface drifting-buoys (hereafter, drifters). Where a drifter measured
the surface velocity, the temporal mean velocity can be estimated by subtracting the altimeter-derived velocity anomaly at
that time from the drifter-measured surface velocity. The method is applied to the surface flow field of the North Pacific,
using TOPEX/POSEIDON and ERS-1/2 altimeter data, and WOCE-TOGA surface drifter data obtained from October 1992 through December
2000. The temporal mean velocity field is estimated with a resolution of quarter degrees in both latitude and longitude. The
obtained mean velocity field clearly shows the Kuroshio and Kuroshio Extension, which are narrower and stronger than the climatological
mean features derived from historical hydrographic data averaged over several decades. Instantaneous velocities are estimated
by summing up these temporal mean velocities and anomalies, every ten days during the eight years. They compare well with
in situ velocities measured by the surface drifters. The instantaneous velocity field shows energetic fluctuation of the Kuroshio
Extension vividly.

This paper describes the conceptual development of a hybrid biological-physical/chemical (P/C) life support system model for a lunar outpost. It presents steps that lead to loop closure and determines mass flow characteristics for an inedible biomass enzyme reactor and an activated sludge bioreactor. Computer modeling techniques were used to determine that the cellulose reactor has the design capabilities to provide significant increases in the plant harvest index. Activated sludge was found to fit design demands for a small, continuous-flow, steady-state system. Systems analysis and component sizing for these two bioreactors and information regarding supporting bioregenerative and physical/chemical components are presented. 相似文献
