In Spacecraft Life Support Systems
SAE Technical Paper Series, 1998<div class="htmlview paragraph">This paper discusses the development problems of the long life hydraulic pump sets based on electrical brushless D.C. motors with hydraulic static supports. The first test results of the new brushless D.C. motors for long life hydraulic pump sets developed in NPP VNIIEM to use on the space station “Alpha” are ...

[Habitability and life support systems].
Kosmicheskaia biologiia i aviakosmicheskaia meditsina, 1989This paper discusses various aspects of space vehicle habitability and life support systems. It describes variations in the chemical and microbial composition of an enclosed atmosphere during prolonged real and simulated flights. The paper gives a detailed description of life support systems and environmental investigations onboard the Mir station.

Fundamentals of Life Support Systems
1996Thermodynamically speaking, man as a living creature is an open system, i.e., he exchanges matter and energy with his environment that maintains its own structure. He is living in his closed terrestrial life support system known as the “biosphere”. The biosphere is a basically closed system in terms of matter, but an open one in terms of energy.

The Life Support Database System
SAE Technical Paper Series, 1991<div class="htmlview paragraph">In 1989 NASA Ames Research Center (ARC) began development of the life Support Database system. This work has progressed through initial requirements analysis, data relationships modeling, and documentation of a detailed conceptual design during the first nine months of the project, followed by a year of database ...

Whither the Life-Support System?
1980The human population of the globe has been increasing according to some superexponential law. One possible form of this relationship is: where N is the total population size, and t the time in years AD. This expression was derived by fitting a model, which assumes the rate of increase to be a weak monotonic increasing function of N, to 24 estimates of ...

Sustaining Our Life Support System
2018Earth scientists have made a major contribution over the last century to extracting materials from the ground. Many of those same skills will be used to be applied to put materials into the ground in a more intelligent and more sustainable manner, whether that material is water, nuclear or toxic waste or perhaps even CO2.
