Occupational health psychologyOccupational health psychology (OHP) is an interdisciplinary area of psychology that is concerned with the health and safety of workers. OHP addresses a number of major topic areas including the impact of occupational stressors on physical and mental health, the impact of involuntary unemployment on physical and mental health, work-family balance, workplace violence and other forms of mistreatment, psychosocial workplace factors that affect accident risk and safety, and interventions designed to improve and/or protect worker health.
Discovery of the neutronThe discovery of the neutron and its properties was central to the extraordinary developments in atomic physics in the first half of the 20th century. Early in the century, Ernest Rutherford developed a crude model of the atom, based on the gold foil experiment of Hans Geiger and Ernest Marsden. In this model, atoms had their mass and positive electric charge concentrated in a very small nucleus.
Energy amplifierIn nuclear physics, an energy amplifier is a novel type of nuclear power reactor, a subcritical reactor, in which an energetic particle beam is used to stimulate a reaction, which in turn releases enough energy to power the particle accelerator and leave an energy profit for power generation. The concept has more recently been referred to as an accelerator-driven system (ADS) or accelerator-driven sub-critical reactor. None have ever been built.
Psychopathy in the workplaceWhile psychopaths typically represent a very small percentage of workplace staff, the presence of psychopathy in the workplace, especially within senior management, can do enormous damage. Indeed, psychopaths are usually most present at higher levels of corporate structure, and their actions often cause a ripple effect throughout an organization, setting the tone for an entire corporate culture. Examples of detrimental effects include increased bullying, conflict, stress, staff turnover, absenteeism, and reduction in both productivity and social responsibility.
Instrument flight rulesIn aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration's (FAA) Instrument Flying Handbook defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals.
OvertoneAn overtone is any resonant frequency above the fundamental frequency of a sound. (An overtone may or may not be a harmonic) In other words, overtones are all pitches higher than the lowest pitch within an individual sound; the fundamental is the lowest pitch. While the fundamental is usually heard most prominently, overtones are actually present in any pitch except a true sine wave. The relative volume or amplitude of various overtone partials is one of the key identifying features of timbre, or the individual characteristic of a sound.
History of lute-family instrumentsLutes are stringed musical instruments that include a body and "a neck which serves both as a handle and as a means of stretching the strings beyond the body". The lute family includes not only short-necked plucked lutes such as the lute, oud, pipa, guitar, citole, gittern, mandore, rubab, and gambus and long-necked plucked lutes such as banjo, tanbura, bağlama, bouzouki, veena, theorbo, archlute, pandura, sitar, tanbur, setar, but also bowed instruments such as the yaylı tambur, rebab, erhu, and the entire family of viols and violins.
Indentation styleIn computer programming, an indentation style is a convention governing the indentation of blocks of code to convey program structure. This article largely addresses the free-form languages, such as C and its descendants, but can be (and often is) applied to most other programming languages (especially those in the curly bracket family), where whitespace is otherwise insignificant. Indentation style is only one aspect of programming style. Indentation is not a requirement of most programming languages, where it is used as secondary notation.
