HeliOS
Helios is a discontinued Unix-like operating system for parallel computers. It was developed and published by Perihelion Software. Its primary architecture is the Inmos Transputer. Helios' microkernel implements a distributed namespace and messaging protocol, through which services are accessed. A POSIX compatibility library enables the use of Unix application software, and the system provides most of the usual Unix utilities. Work on Helios began in the autumn of 1986. Its success was limited by the commercial failure of the Transputer, and efforts to move to other architectures met with limited success. Perihelion ceased trading in 1998. The name of the product was Helios. In the materials they produced, Perihelion Software never referred to the operating system as HeliOS.

Psychiatric Survivors Movement
The psychiatric survivors movement (more broadly consumer/survivor/ex-patient movement) is a diverse association of individuals who either currently access mental health services (known as consumers or service users), or who are survivors of interventions by psychiatry, or who are ex-patients of mental health services. The psychiatric survivors movement arose out of the civil rights movement of the late 1960s and early 1970s and the personal histories of psychiatric abuse experienced by some ex-patients. The key text in the intellectual development of the survivor movement, at least in the USA, was Judi Chamberlin's 1978 text, On Our Own: Patient Controlled Alternatives to the Mental Health System. Chamberlin was an ex-patient and co-founder of the Mental Patients' Liberation Front. Coalescing around the ex-patient newsletter Dendron, in late 1988 leaders from several of the main national and grassroots psychiatric survivor groups felt that an independent, human rights coalition focused on problems in the mental health system was needed. That year the Support Coalition International (SCI) was formed. SCI's first public action was to stage a counter-conference and protest in New York City , in May, 1990, at the same time as (and directly outside of) the American Psychiatric Association's annual meeting. In 2005 the SCI changed its name to MindFreedom International with David W. Oaks as its director. Common themes are "talking back to the power of psychiatry", rights protection and advocacy, and self-determination. While activists in the movement may share a collective identity to some extent, views range along a continuum from conservative to radical in relation to psychiatric treatment and levels of resistance or patienthood.

Minority Influence
Minority influence, a form of social influence, takes place when a member of a minority group influences the majority to accept the minority's beliefs or behavior. This occurs when a small group or an individual acts as an agent of social change by questioning established societal perceptions, and proposing alternative, original ideas which oppose the existing social norms. There are two types of social influence: majority influence (resulting in conformity and public compliance) and minority influence (resulting in conversion). Majority influence refers to the majority trying to produce conformity on the minority, while minority influence is converting the majority to adopt the thinking of the minority group. Unlike other forms of influence, minority influence is often thought of as a more innovative form of social change, because it usually involves a personal shift in private opinion. Examples of minority influence include the Civil Rights Movement in America and the anti-apartheid movement in South Africa .

Megafaunal Wolf
The megafaunal wolf (Canis cf. lupus) was a Late Pleistocene – early Holocene hypercarnivore similar in size to a large extant gray wolf. It had a shorter, broader palate with large carnassial teeth relative to its overall skull size. This adaptation allowed it to prey and scavenge on Pleistocene megafauna. Such an adaptation is an example of phenotypic plasticity. It was once distributed across the northern Holarctic.

Colbert was the second of four Suffren class cruisers built for the French Navy. During the interwar period she served in the Mediterranean.

She underwent a refit in 1941 to augment her light anti-aircraft guns then was placed in care and maintenance at Toulon. She was scuttled at Toulon when the Germans attempted to seize the French Fleet at the end of November 1942. She was raised and scrapped post war in 1948. She was named in honour of Jean-Baptiste Colbert (1619–1683), the Controller General of Finances under King Louis XIV from 1665 to 1683. He was responsible for bringing France out of bankruptcy, restoring the financial health of France and laying the foundation of the French Navy including bases and the training of the officers and men.

Structuralism (Philosophy of Science)
Structuralism[α] (also known as scientific structuralism or as the structuralistic theory-concept) asserts that all aspects of reality are best understood in terms of empirical scientific constructs of entities and their relations, rather than in terms of concrete entities in themselves. Structuralism is an active research program in the philosophy of science, which was first developed in the late 1960s and throughout the 1970s by several analytic philosophers.

Fusospirillary Gingivitis
Acute necrotizing ulcerative gingivitis (ANUG) is a common, non-contagious infection of the gums with sudden onset. The main features are painful, bleeding gums, and ulceration of inter-dental papillae (the sections of gum between adjacent teeth). This disease, along with necrotizing (ulcerative) periodontitis (NP or NUP) is classified as a necrotizing periodontal disease, one of the seven general types of gum disease caused by inflammation of the gums (periodontitis). The often severe gum pain that characterizes ANUG distinguishes it from the more common chronic periodontitis which is rarely painful. If ANUG is improperly treated or neglected, it may become chronic and/or recurrent. The causative organisms are mostly anaerobic bacteria, particularly Fusobacteriota and spirochete species. Predisposing factors include poor oral hygiene, smoking, poor nutrition, psychological stress, and a weakened immune system. When the attachments of the teeth to the bone are involved, the term NUP is used. Treatment of ANUG is by removal of dead gum tissue and antibiotics (usually metronidazole) in the acute phase, and improving oral hygiene to prevent recurrence. Although the condition has a rapid onset and is debilitating, it usually resolves quickly and does no serious harm. The informal name trench mouth arose during World War I as many soldiers developed the disease, probably because of the poor conditions and extreme psychological stress.
