closed ecological systems การใช้

• A closed ecological system must contain at least one autotrophic organism.
• Gray worked on the Biosphere 2 closed ecological system experiment in Arizona.
• Although a fully mechanistic life support system is conceivable, a closed ecological system is generally proposed for life support.
• He financed the Biosphere 2 project, an artificial closed ecological system, which was built between 1987 and 1991.
• In a closed ecological system, any waste products produced by one species must be used by at least one other species.
• While both chemotrophic and phototrophic organisms are plausible, almost all closed ecological systems to date are based on a phototroph such as green algae.
• Such possibilities include mass drivers on the Moon, which launch payloads into space using only electricity, and spinning space colonies with closed ecological systems.
• :You just need to order one closed ecological system, which I shouldn't think needs to weigh as much as 2, 000 tons.
• The main conceptual interest of these objects lies in the fact that they are materially closed ecological systems which are self-sustaining over a period of years.
• Biosphere 2 was originally meant to demonstrate the viability of closed ecological systems to support and maintain human life, defining mission one as eight humans for two years.
• The simulator modeled the inside of a space vehicle and was built to study humans in a closed ecological system at simulated heights of 80, 000 feet and above.
• Human habitation within closed ecological systems in hostile environments, such as Antarctica and outer space, is expensive, typically limited in duration, and restricted to scientific, military, or industrial expeditions.
• Most members of the crew know that they will not survive the journey since it would take several centuries to cross and the ship would not make it with its current rate of attrition of their closed ecological system.
• Man-made closed ecological systems which were created to sustain human life include a long list of spacecraft, Biosphere 2, MELiSSA, and the BIOS-1, BIOS-2, and BIOS-3 projects.
• The 1993 novel " This Other Eden " by Ben Elton featured the development of " claustrospheres " which were closed ecological systems contained within a dome in which people could take refuge in the event of environmental collapse.
• Allen began the first manned Biosphere Test Module experiment in September 1988, residing in the almost fully recyclable closed ecological system environment for three days and setting a world record at that time, proving that closed ecological systems would work with humans inside.

• The plot of the film revolves around two clumsy, dim-witted slackers who, while on a road trip, look for a toilet stop in what they believe is a shopping mall, which in fact turns out to be a " bio-dome ", a form of a closed ecological system in which five scientists are to be hermetically sealed for a year.
• If you look at http : / / www . synergeticpress . com / wp-content / uploads / 2012 / 04 / Bioscience-1993-using-a-closed-system-to-study-the-Earth . pdf ( " Previous research in closed ecological systems " section ) some systems are talked about that were closed in 1968 and were still functional as of the 1993 date that the paper was published ( 25 + years ).
• The scale of Biosphere 2 is unique and Biosphere 2 is already providing unexpected scientific results not possible through other means ( notably the documented, unexpected decline in atmospheric oxygen levels . ) Biosphere 2 will make important scientific contributions in the fields of biogeochemical cycling, the ecology of closed ecological systems, and restoration ecology . " Furthermore, Columbia University assembled outside scientists to evaluate the potential of the facility, and concluded the following : " A group of world-class scientists got together and decided the Biosphere 2 facility is an exceptional laboratory for addressing critical questions relative to the future of Earth and its environment ."
