Allotropy
Allotropy or allotropism () is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as "allotropes" of these elements.
 Allotropes are different structural modifications of an element; the atoms of the element are bonded together in a different manner.
 For example, the allotropes of carbon include diamond (the carbon atoms are bonded together in a tetrahedral lattice arrangement), graphite (the carbon atoms are bonded together in sheets of a hexagonal lattice), graphene (single sheets of graphite), and fullerenes (the carbon atoms are bonded together in spherical, tubular, or ellipsoidal formations).
 The term "allotropy" is used for elements only, not for compounds.
 The more general term, used for any crystalline material, is polymorphism.
 Allotropy refers only to different forms of an element within the same phase (i.e. different solid, liquid or gas forms); these different states are not, themselves, considered to be examples of allotropy.
Transformers technology
Transformers technology refers to various technologies in Transformers series of comic books, films, animated series, and other media.
 The term refers to unusual processes, such as the departure from the standard Transformer ability to change between two different forms, as well as technology utilized by the Transformers in-series.
Akuro
Akuro (悪狼 , akurō ) or "Evil Wolf" is a piece in some variants of the Japanese board game shogi.
 There are typically two akuro at the beginning of the game.
 They can step one square orthogonally sideways or forward, or diagonally forward.
Campus board
A campus board is a training tool that has been widely adopted to improve rock climbing performance.
 Typically, a user ascends or descends the campus board using only their hands.
 Campus boards can take a variety of different forms and may incorporate a variety of materials.
 As one example, a campus board may comprise horizontal thin slats or rails of wood attached to an inclined board in a ladderlike configuration.
 However, some implementations may utilize bolt on climbing holds or sections of pipe.
 A campus board is generally set at overhanging angle of inclination that is between vertical and 20 degrees.
 One consideration for selecting the angle of inclination is the avoidance of any interference that may result between the user's legs and the campus board or wall.

Awithlaknannai Mosona
Awithlaknannai Mosona is a two-player strategy board game from the Zuni Native American Indian tribe of New Mexico, United States.
 It is unknown how old the game is.
 The game was described by Stewart Culin in his book "Games of the North American Indians Volume 2: Games of Skill" (1907).
 In this book, it was named Awithlaknan Mosona.
 Awithlaknannai Mosona resembles another Zuni board game called Kolowis Awithlaknannai (Fighting Serpents) with few minor differences.
 The former having a smaller board, and depending upon the variant, it also has less lines joining the intersection points.
 The rules are the same.
 Awithlaknannai Mosona belongs to the draughts and Alquerque family of games as pieces hop over one another when capturing.
 It is actually more related to Alquerque, since the board is made up of intersection points and lines connecting them.
 It is thought that the Spanish had brought Alquerque to the American Southwest, and Awithlaknannai Mosona may have been an evolution from Alquerque.
 However, in Stewart Culin's 1907 book, the Zunis claim that they had adopted a hunt game from Mexico similar to Catch the Hare and the Fox games of Europe, and transformed it into Awithlaknannai Mosona.
 In these games, one player has more pieces over the other, however, the other player's piece has more powers.
 The Zuni's equalized the numbers of pieces and their powers, and also may have transformed the board making its length far exceed its width.
 Diagonal lines also replaced orthogonal lines altogether.
 However, the hunt game from Mexico may have used an Alquerque board even though the game mechanics of their new game, Awithlaknannai Mosona, were completely different.
Sher-bakar
Sher-bakar is a two-player abstract strategy board game from Punjab, India.
 It is a hunt game.
 It uses an Alquerque board, and therefore, Sher-bakar is specifically a tiger hunt game (or tiger game).
 There are two tigers attempting to elude and capture as many of the other player's pieces which in other hunt games in this part of the world is often referred to as a goat, cows, lamb, or men.
 An interesting and uncommon feature in this game is that the goats, cows, lamb, or men are piled up on four points of the board at the beginning of the game.
 Piling up pieces is an unusual feature in hunt games or any board game in general.
 The only other hunt game that uses this feature is Bagh bandi, a game closely related to Sher-bakar.
 Hereinforth, the white pieces will be referred to as goats.
