Vent (submarine)
In submarine technology a vent is a valve fitted to the top of a submarine's ballast tanks to let air escape from the top of the ballast tank and be replaced by water entering through the opening(s) called "flood ports" or "floods" at the bottom of the tank. In earlier times, the openings at the bottom of the ballast tank were fitted with valves known as Kingston valves. These valves were eliminated in the U.S. Navy between the World Wars.
When on the surface a submarine's ballast tanks are filled with air which gives the vessel its buoyancy and in order for the submarine to submerge water is taken into the ballast tanks through the flood ports at the bottom of the tanks, effacing this excess buoyancy. As the ballast tanks contain air when on the surface it is necessary to allow this air to escape, so that water may then enter the tanks, and this air is allowed to escape via the opened vents in the top of the ballast tanks.
The vents which are used to allow water to enter the submarine's main ballast tanks when it submerges are the main vents and it is air escaping though these that accounts for the spray sometimes seen when submarines dive.
Vent (tailoring)
A vent is a vertical slit rising from the bottom hem of a jacket or a skirt, generally to allow for ease of movement.
In the case of jackets, vents were originally a sporting option, designed to make riding easier, so are traditional on hacking jackets, formal coats such as a morning coat, and, for reasons of pragmatism, overcoats. Today there are three styles of vent: the single-vented style (with one vent, either directly at the center or roughly 3 cm to the right); the ventless style; and the double-vented style (one vent on each side). Vents are convenient, particularly when using a pocket or sitting down, to improve the hang of the jacket, so are now used on most jackets. Single vents jackets are associated with Italian tailoring, while the double-vented style is typically British. (This is not the case with all types of jackets. For instance, dinner jackets traditionally take no vents.)
On skirts, vents are particularly associated with pencil skirts where they may be necessary for free movement, but they may also be added for reasons of style, as they have the effect of exposing more of the legs. The most common style is a single vent of a suitable length at the back of the skirt, but they may be located anywhere.

Ortaköy, Artvin
Ortaköy (formerly, Berta) is a village in the Artvin Central District, Artvin Province, Turkey. Situated at 41°15′N 41°59′E / 41.250°N 41.983°E, its distance to Artvin is 35 kilometres (22 mi). As of 2013, the population of the village was 1,080.
History
The area around Ortaköy was a part of the medieval Georgian principality of Klarjeti and housed the flourishing monastic center Berta, which was founded in the 9th century. The area fell to the eventual Ottoman conquest in the latter half of the 16th century. It was taken over by the Russian Empire in the Russo-Turkish War of 1877-1878, but reverted back to the Turkish control in the aftermath of World War I. The surviving edifice of the Georgian monastery has been used as a mosque.

List of Two and a Half Men characters
The American sitcom Two and a Half Men, created and executive produced by Chuck Lorre and Lee Aronsohn, premiered on CBS on September 22, 2003. The show initially centers on seven characters: brothers Charlie and Alan Harper; Jake Harper, the dimwitted son of Alan and his first ex-wife; Judith Harper-Melnick, Alan's first ex-wife, Herb's ex-wife, and Jake and Milly's mother; Rose, one of Charlie's previous one night stands who continuously stalks him; Evelyn Harper, Charlie and Alan's wealthy, five time widowed, bisexual mother, and Jake's grandmother; and last of all, Berta, Charlie's sharp-tongued housekeeper, who later joins the main cast starting with season two after playing a major recurring role throughout the first season. In season nine, the show is revamped when Charlie is struck and killed by a moving train. Walden Schmidt replaces him as the new owner of the beach house, a recently divorced internet billionaire. In season eleven, Jake moves to Japan and leaves the series, so to replace "the half-man", Charlie's long-lost-daughter moves into the beach house after looking for her late father.
