Orthopedic cast
An orthopedic cast, body cast, plaster cast, or surgical cast, is a shell, frequently made from plaster or fiberglass, encasing a limb (or, in some cases, large portions of the body) to stabilize and hold anatomical structures, most often a broken bone (or bones), in place until healing is confirmed. It is similar in function to a splint.
Plaster bandages consist of a cotton bandage that has been combined with plaster of paris, which hardens after it has been made wet. Plaster of Paris is calcined gypsum (roasted gypsum), ground to a fine powder by milling. When water is added, the more soluble form of calcium sulfate returns to the relatively insoluble form, and heat is produced.
The setting of unmodified plaster starts about 10 minutes after mixing and is complete in about 45 minutes; however, the cast is not fully dry for 72 hours.
Nowadays bandages of synthetic materials are often used, often knitted fiberglass bandages impregnated with polyurethane, sometimes bandages of thermoplastic. These are lighter and dry much faster than plaster bandages. However, plaster can be more easily moulded to make a snug and therefore more comfortable fit. In addition, plaster is much smoother and does not snag clothing or abrade the skin.
Cast (gymnastics)
A cast is a basic skill on uneven bars in artistic gymnastics. From the front hang, a gymnast pikes (allowing the knee to touch the bar) and slides upwards to a handstand. Some gymnasts may perform the move with straddled legs. It is an "A" move in the Code of Points.

Archery
Archery is the sport, practice or skill of using a bow to propel arrows. The word comes from the Latin arcus. Historically, archery has been used for hunting and combat. In modern times, it is mainly a competitive sport and recreational activity. A person who participates in archery is typically called an archer or a bowman, and a person who is fond of or an expert at archery is sometimes called a toxophilite.
History
The bow seems to have been invented in the later Paleolithic or early Mesolithic periods. The oldest signs of its use in Europe come from the Stellmoor in the Ahrensburg valley north of Hamburg, Germany and dates from the late Paleolithic, about 10,000–9000 BC. The arrows were made of pine and consisted of a mainshaft and a 15–20 centimetres (5.9–7.9 inches) long fore shaft with a flint point. There are no definite earlier bows; previous pointed shafts are known, but may have been launched by spear-throwers rather than bows. The oldest bows known so far come from the Holmegård swamp in Denmark. Bows eventually replaced the spear-thrower as the predominant means for launching shafted projectiles, on every continent except Australasia, though spear-throwers persisted alongside the bow in parts of the Americas, notably Mexico and among the Inuit.
Archery (album)
Archery is an album by John Zorn featuring his early "game piece" composition of the same name. The album was first released on Parachute Records in 1982 and later released on Tzadik Records with additional rehearsal takes, (tracks 1-3), as a part of The Parachute Years Box Set in 1997 and as a triple CD set in 2001.
Reception
The Allmusic review by Thom Jurek awarded the album 4 stars stating "The package, as with all Tzadik releases, is stellar, full of three inserts, production notes, and a replica of the original score. If you allow it to, it will change the way you listen to music -- and maybe watch TV, too.".
