Tandem Mass Spectrometry
Tandem mass spectrometry, also known as MS/MS or MS2, involves multiple steps of mass spectrometry selection, with some form of fragmentation occurring in between the stages. In a tandem mass spectrometer, ions are formed in the ion source and separated by mass-to-charge ratio in the first stage of mass spectrometry (MS1). Ions of a particular mass-to-charge ratio (precursor ions) are selected and fragment ions (product ions) are created by collision-induced dissociation, ion-molecule reaction, photodissociation, or other process. The resulting ions are then separated and detected in a second stage of mass spectrometry (MS2).

Porcelain Enamel Coatings
Porcelain enamel is an inorganic-type coating, which is applied to metals or glass for both decorative and functional purposes. This coating is a silica-based solidified glass mass obtained by high-temperature firing (temperature can range between 450 and 1200 °C depending on the substrate). Porcelain enamel coatings differ from ceramic coatings mainly by their glass structure and dilatation coefficient, and from organic paints mainly by the inorganic nature of the matrix and the chemical bond that exists between the coating and the substrate.

Take This Lollipop
Take This Lollipop is a 2011 interactive horror short film and Facebook app written and directed by Jason Zada. It uses the Facebook Connect application to bring viewers themselves into the film, through use of pictures and messages from their own Facebook profiles. Starring actor Bill Oberst Jr. as 'The Facebook Stalker', the film acts to personalize and underscore the dangers inherent in posting too much personal information about oneself on the internet. The information gathered from a viewer's Facebook profile by the film's app is used once, and then deleted. The title is derived from the 1963 song "Please Little Girl Take This Lollipop", written and performed by singer-songwriter Bobby Jameson, which is used in the film. According to Zada, Take This Lollipop was taken offline "a few months" prior to August 2018. The film's website now hosts a Facebook post by him, saying that the data needed had become "quite hard to access" and had affected the functionality of the film.

Great Soviet Encyclopedia
The Great Soviet Encyclopedia (GSE; Russian: Большая советская энциклопедия, БСЭ, Bolshaya sovetskaya entsiklopediya) is one of the largest Russian-language encyclopedias, published by the Soviet state from 1926 to 1990, and again since 2002 by Russia (under the name Bolshaya Rossiyskaya entsiklopediya or Great Russian Encyclopedia). The GSE claimed to be "the first Marxist-Leninist general-purpose encyclopedia".

Anodizing
Anodizing is an electrochemical process by which the thickness of the natural oxide layer present on metals is increased. Anodizing is used to improve the corrosion and wear resistance of the substrate, to enhance the adhesion of coatings and for aesthetics reasons. The properties, chemistry and morphology of the resulting anodic oxide film depend on the anodizing parameters chosen.

Separatist Feminism
Separatist feminism is a form of radical feminism that holds that opposition to patriarchy is best done through focusing exclusively on women and girls. Some separatist feminists believe that men cannot make positive contributions to the feminist movement and that even well-intentioned men replicate the dynamics of patriarchy. Author Marilyn Frye describes separatist feminism as "separation of various sorts or modes from men and from institutions, relationships, roles and activities that are male-defined, male-dominated, and operating for the benefit of males and the maintenance of male privilege – this separation being initiated or maintained, at will, by women". In a tract on socialist feminism published in 1972, the Hyde Park Chapter of the Chicago Women's Liberation Union differentiated between separatism as an "ideological position" and as a "tactical position". In the same document, they further distinguished between separatism as "personal practice" and as "political position".

Celebrity Worship Syndrome
Celebrity worship syndrome (CWS) is an obsessive addictive disorder in which a person becomes overly involved with the details of a celebrity's personal and professional life. Psychologists have indicated that though many people obsess over film, television, sport and pop stars, the only common factor between them is that they are all figures in the public eye. Written observations of celebrity worship date back to the 19th century.

Elephantinae
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are an informal grouping within the proboscidean family Elephantidae. Elephantidae is the only surviving family of proboscideans; extinct members include the mastodons. Elephantidae also contains several extinct groups, including the mammoths and straight-tusked elephants. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. The distinctive features of all elephants include a long proboscis called a trunk, tusks, large ear flaps, massive legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. The pillar-like legs carry their great weight. Elephants are scattered throughout sub-Saharan Africa, South Asia, and Southeast Asia and are found in different habitats, including savannahs, forests, deserts, and marshes. They are herbivorous, and they stay near water when it is accessible. They are considered to be keystone species, due to their impact on their environments. Elephants have a fission–fusion society, in which multiple family groups come together to socialise. Females (cows) tend to live in family groups, which can consist of one female with her calves or several related females with offspring. The groups, which do not include bulls, are usually led by the oldest cow, known as the matriarch. Males (bulls) leave their family groups when they reach puberty and may live alone or with other males. Adult bulls mostly interact with family groups when looking for a mate. They enter a state of increased testosterone and aggression known as musth, which helps them gain dominance over other males as well as reproductive success. Calves are the centre of attention in their family groups and rely on their mothers for as long as three years. Elephants can live up to 70 years in the wild. They communicate by touch, sight, smell, and sound; elephants use infrasound, and seismic communication over long distances. Elephant intelligence has been compared with that of primates and cetaceans. They appear to have self-awareness, and appear to show empathy for dying and dead family members. African bush elephants and Asian elephants are listed as endangered and African forest elephants as critically endangered by the International Union for Conservation of Nature (IUCN). One of the biggest threats to elephant populations is the ivory trade, as the animals are poached for their ivory tusks. Other threats to wild elephants include habitat destruction and conflicts with local people. Elephants are used as working animals in Asia. In the past, they were used in war; today, they are often controversially put on display in zoos, or exploited for entertainment in circuses. Elephants are highly recognisable and have been featured in art, folklore, religion, literature, and popular culture.

Meat Extenders
Meat extenders are non-meat substances with high protein contents used to partially substitue (or extend) the meat content in meat products. Initially devised to reduce costs (as meat is the most expensive ingredient in meat products) they can become now a useful strategy to develop more sustainable and healthier meat products.
