Maladjustment
Maladjustment is a term used in psychology to refer the "inability to react successfully and satisfactory to the demand of one's environment". The term maladjustment can be refer to a wide range of social, biological and psychological conditions. Maladjustment can be both intrinsic or extrinsic. Intrinsic maladjustment is the disparities between the needs, motivations and evaluations of an individual, with the actual reward gain through experiences. Extrinsic maladjustment on the other hand, is refer to when an individual's behavior is does not meet the cultural or social expectation of society. The causes of maladjustment can be attributed to a wide variety of factors, including: family environment, personal factors, and school-related factors. Maladjustment affects an individual's development and the ability to maintain a positive interpersonal relationship with others. Often maladjustment emerges during early stages of childhood, when a child is in the process of learning methods to solve problem that occurs in interpersonal relationship in their social network. A lack of intervention for individuals who are maladjusted can cause negative effects later on in life.

Number of the Beast
The number of the beast (Greek: Ἀριθμὸς τοῦ θηρίου, Arithmos tou Thēriou), also known as The devil's number is a term in the Book of Revelation, of the New Testament, that is associated with the Beast of Revelation in chapter 13, verse 18. In most manuscripts of the New Testament and in English translations of the Bible, the number of the beast is six hundred and sixty-six or χξϛ (the number not being representable by the repetition of 6 or ϛ three times – Greek for 6 is ϛ, but ϛϛϛ is not six hundred sixty-six). Papyrus 115 (which is the oldest preserved manuscript of the Revelation (As of 2017)), as well as other ancient sources like Codex Ephraemi Rescriptus, give the number of the beast as χιϛ or χιc (transliterable in Arabic numerals as 616) (χιϛ), not 666; critical editions of the Greek text, such as the Novum Testamentum Graece, note 616 as a variant.

Old Azeri Language
Old Azeri (Persian: آذری‌ باستان‎), also referred to as Azeri or Azari (Persian: آذری‎ Āḏarī [ɑːzæri]), is the extinct Iranian language that was once spoken in Azerbaijan (historic Azerbaijan, also known as Iranian Azerbaijan) before the Turkification of the Azeris. Some linguists believe the southern Tati varieties of Iranian Azerbaijan around Takestan such as the Harzandi and Karingani dialects to be remnants of Azeri. In addition, Old Azeri is known to have strong affinities with Talysh. Azeri was the dominant language in Azerbaijan before it was replaced by Azerbaijani, which is a Turkic language.

Cognitive Evaluation Theory
Cognitive evaluation theory (CET) is a theory in psychology that is designed to explain the effects of external consequences on internal motivation. Specifically, CET is a sub-theory of self-determination theory that focuses on competence and autonomy while examining how intrinsic motivation is affected by external forces in a process known as motivational "crowding out." CET uses three propositions to explain how consequences affect internal motivation:

Scottish Highlands
The Highlands (Scots: the Hielands; Scottish Gaelic: a’ Ghàidhealtachd [ə ˈɣɛːəl̪ˠt̪ʰəxk], 'the place of the Gaels') is a historical region of Scotland. Culturally, the Highlands and the Lowlands diverged from the Late Middle Ages into the modern period, when Lowland Scots replaced Scottish Gaelic throughout most of the Lowlands. The term is also used for the area north and west of the Highland Boundary Fault, although the exact boundaries are not clearly defined, particularly to the east. The Great Glen divides the Grampian Mountains to the southeast from the Northwest Highlands. The Scottish Gaelic name of A' Ghàidhealtachd literally means "the place of the Gaels" and traditionally, from a Gaelic-speaking point of view, includes both the Western Isles and the Highlands.The area is very sparsely populated, with many mountain ranges dominating the region, and includes the highest mountain in the British Isles, Ben Nevis. During the 18th and early 19th centuries the population of the Highlands rose to around 300,000, but from c. 1841 and for the next 160 years, the natural increase in population was exceeded by emigration (mostly to Canada, the United States, Australia and New Zealand, and migration to the industrial cities of Scotland and England.):xxiii, 414 and passim The area is now one of the most sparsely populated in Europe. At 9.1/km2 (24/sq mi) in 2012, the population density in the Highlands and Islands is less than one seventh of Scotland's as a whole, comparable with that of Bolivia, Chad and Russia . The Highland Council is the administrative body for much of the Highlands, with its administrative centre at Inverness. However, the Highlands also includes parts of the council areas of Aberdeenshire, Angus, Argyll and Bute, Moray, North Ayrshire, Perth and Kinross, Stirling and West Dunbartonshire. The Scottish Highlands is the only area in the British Isles to have the taiga biome as it features concentrated populations of Scots pine forest: see Caledonian Forest. It is the most mountainous part of the United Kingdom .

Indeterminacy
Indeterminacy, in philosophy, can refer both to common scientific and mathematical concepts of uncertainty and their implications and to another kind of indeterminacy deriving from the nature of definition or meaning. It is related to deconstructionism and to Nietzsche's criticism of the Kantian noumenon.

Conservation-Restoration of Cultural Heritage
The conservation-restoration of cultural heritage focuses on protection and care of tangible cultural heritage, including artworks, architecture, archaeology, and museum collections. Conservation activities include preventive conservation, examination, documentation, research, treatment, and education. This field is closely allied with conservation science, curators and registrars.

Hybridoma Technology
Hybridoma technology is a method for producing large numbers of identical antibodies (also called monoclonal antibodies). This process starts by injecting a mouse (or other mammal) with an antigen that provokes an immune response. A type of white blood cell, the B cell, produces antibodies that bind to the injected antigen. These antibody producing B-cells are then harvested from the mouse and, in turn, fused with immortal B cell cancer cells, a myeloma,[clarification needed] to produce a hybrid cell line called a hybridoma, which has both the antibody-producing ability of the B-cell and the longevity and reproductivity of the myeloma. The hybridomas can be grown in culture, each culture starting with one viable hybridoma cell, producing cultures each of which consists of genetically identical hybridomas which produce one antibody per culture (monoclonal) rather than mixtures of different antibodies (polyclonal). The myeloma cell line that is used in this process is selected for its ability to grow in tissue culture and for an absence of antibody synthesis. In contrast to polyclonal antibodies, which are mixtures of many different antibody molecules, the monoclonal antibodies produced by each hybridoma line are all chemically identical. The production of monoclonal antibodies was invented by César Milstein and Georges J. F. Köhler in 1975. They shared the Nobel Prize of 1984 for Medicine and Physiology with Niels Kaj Jerne, who made other contributions to immunology. The term hybridoma was coined by Leonard Herzenberg during his sabbatical in César Milstein's laboratory in 1976–1977.

Sensory Memory
During every moment of an organism's life, sensory information is being taken in by sensory receptors and processed by the nervous system. Sensory information is stored in sensory memory just long enough to be transferred to short-term memory. Humans have five traditional senses: sight, hearing, taste, smell, touch. Sensory memory (SM) allows individuals to retain impressions of sensory information after the original stimulus has ceased. A common demonstration of SM is a child's ability to write letters and make circles by twirling a sparkler at night. When the sparkler is spun fast enough, it appears to leave a trail which forms a continuous image. This "light trail" is the image that is represented in the visual sensory store known as iconic memory. The other two types of SM that have been most extensively studied are echoic memory, and haptic memory; however, it is reasonable to assume that each physiological sense has a corresponding memory store. Children for example have been shown to remember specific "sweet" tastes during incidental learning trials but the nature of this gustatory store is still unclear. However, sensory memories might be related to a region of the thalamus, which serves as a source of signals encoding past experiences in the neocortex.
