Fold (geology)

A geological fold occurs when one or a stack of originally flat and planar surfaces, such as sedimentary strata, are bent or curved as a result of permanent deformation. Synsedimentary folds are those due to slumping of sedimentary material before it is lithified. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur singly as isolated folds and in extensive fold trains of different sizes, on a variety of scales.

Folds form under varied conditions of stress, hydrostatic pressure, pore pressure, and temperature gradient, as evidenced by their presence in soft sediments, the full spectrum of metamorphic rocks, and even as primary flow structures in some igneous rocks. A set of folds distributed on a regional scale constitutes a fold belt, a common feature of orogenic zones. Folds are commonly formed by shortening of existing layers, but may also be formed as a result of displacement on a non-planar fault (fault bend fold), at the tip of a propagating fault (fault propagation fold), by differential compaction or due to the effects of a high-level igneous intrusion e.g. above a laccolith.

Fold (higher-order function)

In functional programming, fold – also known variously as reduce, accumulate, aggregate, compress, or inject – refers to a family of higher-order functions that analyze a recursive data structure and through use of a given combining operation, recombine the results of recursively processing its constituent parts, building up a return value. Typically, a fold is presented with a combining function, a top node of a data structure, and possibly some default values to be used under certain conditions. The fold then proceeds to combine elements of the data structure's hierarchy, using the function in a systematic way.

Folds are in a sense dual to unfolds, which take a "seed" value and apply a function corecursively to decide how to progressively construct a corecursive data structure, whereas a fold recursively breaks that structure down, replacing it with the results of applying a combining function at each node on its terminal values and the recursive results (catamorphism as opposed to anamorphism of unfolds).

Pacific (album)

Pacific (stylized as pacific) is the second studio album by Japanese musical group NEWS, released on November 7, 2007. The album reached the number one position on the Oricon Daily Album Chart and Oricon Weekly Album Chart. Four singles have been released from this album. The limited edition includes a 74-page photobook, while the regular edition comes with an 18-page booklet and 2 bonus tracks. It was released simultaneously with the single "Weeeek."

Tie-ups and theme songs

"Teppen" was used as the theme song to Fuji TV's coverage of the Women's Volleyball World Grand Prix 2005.

Pacific Marine Ecozone (CEC)

The Pacific Marine Ecozone is a Canadian and American marine ecozone extending to the international waters of the Pacific Ocean from the coasts of Alaska, British Columbia, Washington and Oregon. The islands within the Canadian portion are part of the adjacent Pacific Maritime ecozone.

Famous for its tourism and an important shipping channel for Canada, the zone is subject to intense human activity which has damaged ecosystems. Primary effects include overfishing, pollution and even direct habitat destruction. The large and increasing population in nearby coastal areas, including the major centres of Vancouver and Seattle, exerts significant strain on the natural habitats within this ecozone.

Geography

The large rivers flowing from the Rocky Mountains are a source of nutrients for this ecologically diverse region. They enter the shallow waters over the continental shelf, which underlays the entire ecozone and represents the edge of the North American tectonic plate. This plate is constantly folding under the Pacific Plate, causing volcanic activity at their juncture and earthquakes along the coast.

Pacific (video game)

Pacific is a graphic adventure game created by Gamelearn to be training for leadership. Pacific uses the g-learning methodology, which incorporates game-based learning, gamification techniques, and simulation.

Together with Triskelion and Merchants, Pacific is one of the games developed by Gamelearn for soft skills training.

Description

Pacific is primarily a complete course with techniques, tips and tools applicable to learning how to become a leader. The contribution of the secrets on leadership of over 200 leading executives and CEOs (whom we interviewed) as well as Gamelearn's 15 years of experience in corporate training guarantee Pacific's theoretical approach, which is based on six key notions:

Gamelearn's developers decided to set the story in an environment of survival and cooperation: a group of people that are lost on an island in the Pacific. A favorable setting to explain the benefits of teamwork and staying motivated.
