Formation of higher plant component microbial community in closed ecological system

Acta Astronautica, 2001
Closed ecological systems (CES) place at the disposal of a researcher unique possibilities to study the role of microbial communities in individual components and of the entire system. The microbial community of the higher plant component has been found to form depending on specific conditions of the closed ecosystem: length of time the solution is ...

Man as a component of a closed ecological life support system

Life support & biosphere science : international journal of earth space, 1996
Material support of all manned space flights so far has been provided from a prestored stock of substances or replenished from the Earth's biosphere. Exploration of space will, however, become real only when man is able to break away from Earth completely, when he will be accompanied by a system providing everything necessary to sustain full-valued ...

Mineral recovery system for a Closed Ecology Experiment Facility (CEEF).

Life support & biosphere science : international journal of earth space, 1999
A unique recovery system, which consists of electrodialysis (ED) and crystallization processes, is proposed for NaCl (salt) from waste water after oxidation of urine. NaCl recovery characteristics from the oxidized urine, which contains KCl and NO3- impurities, were experimentally evaluated.

Optimum control of closed ecological systems: mathematical aspects.

Life support & biosphere science : international journal of earth space, 1999
Optimum control of a closed ecological system (CES) is not possible without adequate CES description and appropriate evaluation of factors, which act upon the system and introduce additional errors and uncertainties into the forecast of the CES state. The statement about key significance of stationary state consideration for further CES development is ...
