A two-compartment standard is common for......
  • one-day international (cricket)

    In his best-known and most influential work, One-Dimensional Man: Studies in the Ideology of Advanced Industrial Society (1964), Marcuse argued that the modern “affluent” society represses even those who are successful within it, while maintaining their complacency through the ersatz satisfactions of consumer culture. By cultivating such shallow forms of experience and.....
  • one-dimensional motion (physics)
    According to Newton’s first law (also known as the principle of inertia), a body with no net force acting on it will either remain at rest or continue to move with uniform speed in a straight line, according to its initial condition of motion. In fact, in classical Newtonian mechanics, there is no important distinction between rest and uniform motion in a straight line; they may be regarded...
  • one-directional change (society)
    This type of change continues more or less in the same direction. Such change is usually cumulative and implies growth or increase, such as that of population density, the size of organizations, or the level of production.

    Since the late 1970s, two types of encryption have emerged. Conventional symmetric encryption requires the same key for both encryption and decryption. A common symmetric encryption system is the Data Encryption Standard (DES), an extremely complex algorithm approved as a standard by the U.S. National Bureau of Standards. Asymmetric encryption, or public-key cryptography, requires a pair of......
  • one-parent family
    Since the 1970s, one-parent families have acquired an importance not adequately reflected in traditional law.

The head......

Its main applications are to polymers and particulate matter. The method has been used to.....
  • one-place predicate (logic)
    Being an even number is a property that some individuals can have. Expressions that attribute a property to an individual are (monadic) predicates.

  • one-ring circus
    Continental European and British circuses generally retained the one-ring format in the mid- to late 19th century; their programs were often of the highest calibre, and their tents may have seated as many as 5,000 spectators. In order to maintain the one-ring design while expanding the area beneath the tent, the European tent was designed with the four centre poles forming a square instead of a......

For a single, one-of-a-kind product, for example, a building, a ship, or the prototype of a product such as an airplane or a large computer, resources are brought together only once. Because of the singular nature of project systems, special methods of management have been developed to contain the costs of......
