Sodium hydride

Sodium hydride is the chemical compound with the empirical formula NaH. It is primarily used as a strong, yet combustable base in organic synthesis. NaH is representative of the saline hydrides, meaning it is a salt-like hydride, composed of Na⁺ and H⁻ ions, in contrast to the more molecular hydrides such as borane, methane, ammonia and water. It is an ionic material that is insoluble in organic solvents (although soluble in molten Na), consistent with the fact that H⁻ remains an unknown anion in solution. Because of the insolubility of NaH, all reactions involving NaH occur at the surface of the solid.

Basic properties and structure

NaH is produced by the direct reaction of hydrogen and liquid sodium. Pure NaH is colorless, although samples generally appear grey. NaH is ca. 40% denser than Na (0.968 g/cm³).

NaH, like LiH, KH, RbH, and CsH, adopts the NaCl crystal structure. In this motif, each Na⁺ ion is surrounded by six H⁻ centers in an octahedral geometry. The ionic radii of H⁻ (146 pm in NaH) and F⁻ (133 pm) are comparable, as judged by the Na−H and Na−F distances.

Baton (law enforcement)

A baton or truncheon (also called a cosh, billystick, billy club, nightstick, sap, blackjack, stick) is essentially a club of less than arm's length made of wood, rubber, plastic or metal. They are carried for forced compliance and self-defense by law-enforcement officers, correctional staff, security-industry employees and (less often) military personnel. Other uses for truncheons and batons include crowd control or the dispersal of belligerent or non-compliant people.

A truncheon or baton may be used to strike, jab, block, bludgeon and aid in the application of armlocks. The usual striking or bludgeoning action is not produced by a simple and direct hit, as with an ordinary blunt object, but rather by bringing the arm down sharply while allowing the truncheon to pivot nearly freely forward and downward, so moving its tip much faster than its handle – effectively a slingshot action, only without releasing. Sometimes, they also are employed as weapons by criminals and other law-breakers because of their easy concealment. As a consequence, they are illegal for non-authorized civilian use in many jurisdictions around the world. They have a common role to play, too, in the rescuing of trapped individuals—for instance, people caught in blazing cars or buildings—by smashing windows or even doors.

Vau i Dejës

Vau i Dejës (Albanian pronunciation: [ˌvau i ˈdɛjəs]), English: Deja's Ford, is a town and a municipality in Shkodër County, northwestern Albania. It was formed at the 2015 local government reform by the merger of the former municipalities Bushat, Hajmel, Shllak, Temal, Vau i Dejës and Vig-Mnelë, that became municipal units. The seat of the municipality is the town Vau i Dejës. The total population is 30,438 (2011 census), in a total area of 499.09 km². The population of the former municipality at the 2011 census was 8,117.

Vau i Dejës (or Vau Dejës or Vau-Dejës) also refers to the city center for the municipality, which is sometimes referred to as Laç or Laç-Vau i Dejës. Located in the norther region of Zadrima, Vau i Dejës is intersected by the Drin and Gjadër rivers. It is also strategically about 41 kilometers from the Adriatic Sea. Settlements in the area can be dated back to the 15th century, while the main city of Vau i Dejës was developed to house workers during the construction of the Vau i Dejës hydroelectric dam from 1971- 73. After the completion of the dam, families displaced from the flood waters began to inhabit the city. Today Vau i Dejës is composed of 8 villages and a city center. The population in 2008 was 12,345. The municipality covers a total of 31 km and is composed of 1 city center and 8 villages. The villages of Vau i Dejës are Mjedë, Spathar, Shelqet, Kacë, Narac, Dush, Gomsiqe, and Karmë. It is the seat of the Roman Catholic Diocese of Sapë.
