Limnology and Oceanography, Vol. 63, No. 2 (March 2018), pp. 687-701 (15 pages) We investigated anaerobic nitrogen (N) cycling in the water column of Lake Kivu, a deep meromictic tropical lake in East ...

An alternating aerobic and anoxic (AAA) system is a continuous-flow, activated-sludge process in which the environmental conditions necessary to meet the specific requirements for aerobic ...

Biology is full of molecular machines, such as motor proteins and ATP synthase, that operate self-sufficiently through cycles of oxidation and reduction. A team of human chemists at the University of ...

The film discusses various chemical processes, particularly focusing on oxidation and reduction reactions involving elements like hydrogen, oxygen, coke, magnesium, and aluminum. It explains how these ...
