Decomposition

Decomposition is the process by which organic substances are broken down into a much simpler form of matter. The process is essential for recycling the finite matter that occupies physical space in the biome. Bodies of living organisms begin to decompose shortly after death. Animals, such as worms, also help decompose the organic materials. Organisms that do this are known as decomposers. Although no two organisms decompose in the same way, they all undergo the same sequential stages of decomposition. The science which studies decomposition is generally referred to as taphonomy from the Greek word τάφος taphos, meaning tomb.

One can differentiate abiotic from biotic decomposition (biodegradation). The former means "degradation of a substance by chemical or physical processes, e.g. hydrolysis. The latter one means "the metabolic breakdown of materials into simpler components by living organisms", typically by microorganisms.

Animal decomposition

Decomposition begins at the moment of death, caused by two factors: autolysis, the breaking down of tissues by the body's own internal chemicals and enzymes, and putrefaction, the breakdown of tissues by bacteria. These processes release gases that are the chief source of the unmistakably putrid odor of decaying animal tissue.

Merzbow

Masami Akita (秋田 昌美, Akita Masami, born December 19, 1956), better known by his stage name Merzbow (メルツバウ, Merutsubau), is a Japanese noise musician. Since 1980, he has released over 400 recordings.

The name Merzbow comes from German dada artist Kurt Schwitters' artwork, Merzbau, where Schwitters transformed the interior of his house using found objects. This was chosen to reflect Akita's dada influence and junk art aesthetic. In addition to this, Akita has cited a wide range of musical influences from progressive rock, heavy metal, free jazz, and early electronic music to non-musical influences like dadaism, surrealism, and fetish culture. Since the early 2000s, he has been inspired by animal rights and environmentalism, and has become a vegan.

As well as being a prolific musician, he has been a writer and editor for several books and magazines in Japan, and has written several books of his own. He has written about a variety of subjects, mostly about music, modern art, and underground culture. His more renowned works have been on the topics of BDSM and Japanese bondage. Other art forms Akita has been interested in include painting, photography, filmmaking, and Butoh dance.

Decomposition (computer science)

Decomposition in computer science, also known as factoring, is breaking a complex problem or system into parts that are easier to conceive, understand, program, and maintain.

Overview

There are different types of decomposition defined in computer sciences:

More generally, functional decomposition in computer science is a technique for mastering the complexity of the function of a model. A functional model of a system is thereby replaced by a series of functional models of subsystems.
