Merge Antoni K pi ski date December 2009 Information metabolism is a psychology psychological theory of human social interaction s based on information processing Citation needed date February 2007 . It was developed in Eastern Europe by Antoni K pi ski who criticized works of Carl Jung . In the late 1970s, Lithuania n psychologist Au ra Augustinavi i t created socionics , a personality typology based on the typology of Carl Jung and the theory of information metabolism of Antoni K pi ski , a Poland Polish psychiatrist interested in schizophrenia . According to Augustinavi i t , humans can be classified in terms of types of information processing , or information metabolism . Psychological features such as attention, interests, memory and motivation are components of this theory of information metabolism. This theory of information metabolism is built upon an analogy to biological metabolism . According to this analogy, information that arrives as signals from outside an organism are available for information metabolism just as food is available for energy metabolism. The brain is the key information metabolism system. The brain and information metabolism deal with a two way flow of signals metabolism of input signals results in the production of output.

Urban Metabolism is a scientific modelling model to facilitate the description and analysis of the flows of the materials and energy within cities, such as undertaken in a Material flow analysis of a city. First used as an exploration and comparison modeling tool by Abel Wolman in The metabolism of Cities . The use of the Urban Metabolism model offers benefits to studies of the sustainability of cities by providing a unified or holistic viewpoint to encompass all of the activities of a city in a single model. Uses The concept of urban metabolism has been used to describe the resource consumption and waste generation of the cities for some time see for example, Wolman, 1965 . Historically, first suggestions that quasi organism analogies may help in understanding cities including references to metabolism were made by the Chicago school of urban sociology Burgess and others . Presently, the great advocate and populariser of the term has been the British educator and author Herbert Girardet . More recently the metabolism frame of reference has been used in the reporting of environmental information in Australia and it has been suggested that it can be used to define the sustainability of a city within the ecosystems capacity to support it. A strong theme in present literature on urban sustainability is that of the need to view the urban system as a whole if we are to best understand and solve the complex problems.

Sulfur metabolism is vital for all living organism s as it is a constituent of a number of essential organic molecules like cysteine , methionine , coenzyme A , and iron sulfur cluster s. These compounds are involved in a number of essential cellular processes such as protein biosynthesis or the transfer of electrons and acyl group s. Sulfur, therefore, is an essential component of all living cells. The importance of sulfur is well represented by the sulfhydryl thiol functional group, lying at the centre of many chemical reactions in biology. Thiol based reactions have diverse biological functions thiols in thioredoxin s provide reductive power for the synthesis of biological molecules thiols in coenzyme A facilitate the oxidation of pyruvic acid pyruvate and fatty acid s to generate energy for living cells and thiols in glutathione and mycothiol are involved in detoxifying hazardous molecules, as well as maintaining the redox balance of living cells.

The average adult body contains in total approximately 1 kg, 99 in the skeleton in the form of calcium phosphate salts.
