Mutator Method
In computer science, a mutator method is a method used to control changes to a variable. They are also widely known as setter methods. Often a setter is accompanied by a getter (together also known as accessors), which returns the value of the private member variable. The mutator method is most often used in object-oriented programming, in keeping with the principle of encapsulation. According to this principle, member variables of a class are made private to hide and protect them from other code, and can only be modified by a public member function (the mutator method), which takes the desired new value as a parameter, optionally validates it, and modifies the private member variable. Mutator methods can be compared to assignment operator overloading but they typically appear at different levels of the object hierarchy. Mutator methods may also be used in non-object-oriented environments. In this case, a reference to the variable to be modified is passed to the mutator, along with ...

Garbage Collection (computer Science)
In computer science, garbage collection (GC) is a form of automatic memory management. The ''garbage collector'' attempts to reclaim memory which was allocated by the program, but is no longer referenced; such memory is called '' garbage''. Garbage collection was invented by American computer scientist John McCarthy around 1959 to simplify manual memory management in Lisp. Garbage collection relieves the programmer from doing manual memory management, where the programmer specifies what objects to de-allocate and return to the memory system and when to do so. Other, similar techniques include stack allocation, region inference, and memory ownership, and combinations thereof. Garbage collection may take a significant proportion of a program's total processing time, and affect performance as a result. Resources other than memory, such as network sockets, database handles, windows, file descriptors, and device descriptors, are not typically handled by garbage collection, but ...

Mutator Genotype
In genetics, the mutation rate is the frequency of new mutations in a single gene or organism over time. Mutation rates are not constant and are not limited to a single type of mutation; there are many different types of mutations. Mutation rates are given for specific classes of mutations. Point mutations are a class of mutations which are changes to a single base. Missense and Nonsense mutations are two subtypes of point mutations. The rate of these types of substitutions can be further subdivided into a mutation spectrum which describes the influence of the genetic context on the mutation rate. There are several natural units of time for each of these rates, with rates being characterized either as mutations per base pair per cell division, per gene per generation, or per genome per generation. The mutation rate of an organism is an evolved characteristic and is strongly influenced by the genetics of each organism, in addition to strong influence from the environment. The up ...

Heat Exchanger
A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.

Mutator (comics)
''D.P. 7'' was a comic book series published by Marvel Comics as part of its New Universe imprint. It ran for 32 issues and an ''Annual'' (January 1987), which were published from 1986 to 1989. The title stands for Displaced Paranormals and refers to the seven main characters of the series (who never refer to themselves as displaced). All of them received superhuman powers as a result of the stellar phenomenon known as the White Event. ''D.P. 7'' was the only New Universe series to maintain a stable creative team during its first year: its entire run was written by Mark Gruenwald, penciled by Paul Ryan, and colored by Paul Becton. Inker Danny Bulanadi (who began work on the title with issue #10) and letterer Janice Chiang (who began with issue #16) also stayed with ''D.P. 7'' through to the final issue. Publication history Eager for the chance to work on "a virgin universe", writer Mark Gruenwald signed on to the New Universe staff and developed ''D.P. 7'', shocking m ...

Unreal (1998 Video Game)
''Unreal'' is a first-person shooter video game developed by Epic MegaGames and Digital Extremes and published by GT Interactive for Microsoft Windows in May 1998. It was powered by Unreal Engine, an original game engine. The game reached sales of 1.5 million units by 2002. Since the release of ''Unreal'', the franchise has had one sequel and two different series based on the ''Unreal'' universe. One official bonus pack, the Epic-released Fusion Map Pack, can be downloaded free of charge. ''Unreal Mission Pack: Return to Na Pali'', developed by Legend Entertainment, was released in June 1999, and added 17 new missions to the single-player campaign of ''Unreal''. ''Unreal'' and ''Return to Na Pali'' would later be bundled together as ''Unreal Gold''. Additionally, the games were updated to run on the ''Unreal Tournament'' version of the game engine. Plot The player takes on the part of Prisoner 849, aboard the prison spacecraft ''Vortex Rikers''. During transport to a moon-based ...
