Closed Ecological System (CES)

Biosphere 2 sits on a sprawling 40-acre (16-hectare) science campus that is open to the public.

           

               Closed Ecological Systems are ecosystems that do not rely on matter exchange with any part outside the system. The term is most often used to describe small manmade ecosystems. Such systems are scientifically interesting and can potentially serve as a life support system during space flights, in space stations or space habitats. In a closed ecological system, any waste products produced by one species must be used by at least one other species. If the purpose is to maintain a life form, such as a mouse or a human, waste products such as carbon dioxide, feces and urine must eventually be converted into oxygen,food, and water.

A closed ecological system must contain at least one autotrophic organism. While both chemotrophic and phototrophic organisms are plausible, almost all closed ecological systems to date are based on a phototroph such as green algae.

 

Closed Ecological Systems for Life Support:--

                 A life support system that approaches complete internal sustainability and which is biologically-based is termed a closed ecological system, meaning that it is essentially materially closed, energetically and informationally open, and recycling its major elements and nutrients. Both the CELSS and Closed Ecological Systems have generally included just a few species of plants and/or algae as their biological component, in addition to the crew compartments and associated mechanical/computer operational technologies. Energetically, such a system must be open or it would decline due to increasing entropy. The light needed for photosynthesis is supplied by artificial lights or by sunlight, direct or delivered through light pipes. A heat sink on the outside receives surplus heat from the system. Usually, it is safer to house the energy-generating unit outside the sealed life support zone. This will also lessen the amount of air-scrubbing that is required if the energy production method produces pollutants. But, while the definition of a closed ecological life support system does not require energy production within its sealed boundary, it is certainly true that lessening energetic requirements and the accomplishment of energy generation in space via solar arrays, nuclear energy, use of extra-terrestrial energy resources, etc.) are important considerations in reducing logistical dependence on resupply from Earth.

Agricultural Robot

               An agricultural robot or agribot is a robot deployed for agricultural purposes. The main area of application of robots in agriculture is at the harvesting stage. Fruit picking robots, driverless tractor / sprayer, and sheep shearing robots are designed to replace human labour. The agricultural industry is behind other complementary industries in using robots because the sort of jobs involved in agriculture are not straightforward, and many repetitive tasks are not exactly the same every time. In most cases, a lot of factors have to be considered (e.g., the size and colour of the fruit to be picked) before the commencement of a task. Robots can be used for other horticultural tasks such as pruning, weeding, spraying and monitoring. Robots can also be used in livestock applications (livestock robotics) such as milking, washing and castrating.

Run Time Polymorphism.....

Brain injuries became so genius on......!

Brain injuries became so genius on.....  

Incident is turning into the enjoys good if what! Sometimes nature is possible from charisma, as happened with an American man. ' try to find and also surprised in how this person's brain injury made him a genius of mathematics. the few success to them also.
This interesting event "live science" in a report printed. scientists have said that the reason behind this is that after head injury in the last part of the Crown of a special area, which became more active cortex says Praitl.

What had happened to someone:

Actually, Jason Padget by that time Tacoma (Washington) A simple - there was little furniture salesman did not come until he hears her. 2002 out of the thing when one day at a time severely attacked by two men on Jason. In the event of brain injury on Jason, but his kidneys were also injured. After recovering from injuries that occur after trauma stress disorder him surrounded by.

Usually it is a psychological condition which is dealt with War Veterans . But as - as it was time elapses , Jason Padget felt that now he is starting to see the world differently . It seemed that everything is cast in the shape Jyometrikl . Suddenly her way - have come to shape complex Jyometrikl .

Increased scientific interest:

Research has been initiated . University of Miami professor Berit Brogard Jason and his colleagues to study the brain, his MRI ( magnetic resonance imaging ) is also provided . Brain scans showed that after the attack the Left Praitl Jason was excited cortex , which this miracle was possible . Moreover, the scientists arrived at the conclusion that a man of Jason 's caliber Susupt condition may occur in the brain . Jason was overwhelmed by the beauty of a physicist . Jason 's days have changed . He persuaded Jason to join the college , where he began the study of Number Theory .
