Slide (musical ornament)

The slide (Schleifer in German, Coulé in French, Superjectio in Latin) is a musical ornament often found in baroque musical works, but used during many different periods. It instructs the performer to begin two or three scale steps below the marked note and "slide" upward—that is, move stepwise diatonically between the initial and final notes. Though less frequently found, the slide can also be performed in a descending fashion.

History

In The Interpretation of Early Music, Robert Donington surveys many treatises to ascertain the history of the slide. Writing in 1654, John Playford noted that the slide can be used in ascending (he called it "elevation") or in descending (he called it "double backfall") forms.Christopher Simpson described the figure in his Division Violist: "Sometimes a note is graced by sliding to it from the third below, called an 'elevation', now something obsolete. Sometimes from the third above; which we call a double-backfall. This sliding a third, up, or down, is always done upon one string."Thomas Mace (1676) notes that the + sign above a note indicates its use.

Pistol slide

The slide is the part of the weapon on a majority of semi-automatic pistols that moves during the operating cycle and generally houses the firing pin or striker and the extractor, and serves as the bolt. It is spring-loaded so that once it has moved to its rearmost position in the firing cycle, spring tension brings it back to the starting position chambering a fresh cartridge during the motion provided that the magazine is not empty.

Through the principles of recoil or blowback operation, the slide is forced back with each shot. Generally, this action serves three purposes: ejecting the spent casing, cocking the hammer or striker for the next shot, and loading another cartridge into the chamber when the slide comes forward.

Once the magazine and chamber both are empty, the slide will lock back, released only when the slide stop is depressed; if a new magazine is inserted before the slide stop is depressed then a new cartridge will be chambered.

Some handguns also utilise the slide stop as a means of releasing the slide, when the slide stop is held upwards for purposes such as field stripping eliminating the need for any further lock mechanisms and the room that these may use inside the gun.

Slide (footwear)

A slide is a shoe that is backless and open-toed, essentially an open-toed mule. Generally, all slides are not sandals. Thongs and flip flops are normally classified separately. Slides can be high-heeled, flat-heeled or somewhere in between, and may cover nearly the entire foot from ankle to toe, or may have only one or two narrow straps. They usually include a single strap or a sequence of straps across the toes and the lower half of the foot to hold the shoe on the foot. The term is descriptive in that this shoe is easy to 'slide' on and off the foot when the wearer wants to do so.

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.
