Q: Context_1 : The Mask of Orpheus is an opera with music by Harrison Birtwistle and a libretto by Peter Zinovieff. It was premiered in London at the English National Opera on 21 May 1986 to great critical acclaim. A recorded version conducted by Andrew Davis and Martyn Brabbins has also received good reviews. The work is around three hours long. Context_2 : The screw turbine is a water turbine which uses the principle of the Archimedean screw to convert the potential energy of water on an upstream level into work. It may be compared to the water wheel. The turbine consists of a rotor in the shape of an Archimedean screw which rotates in a semicircular trough. Water flows into the turbine and its weight presses down onto the blades of the turbine, which in turn forces the turbine to turn. Water flows freely off the end of the turbine into the river. The upper end of the screw is connected to a generator through a gearbox. Context_3 : The Turn of the Screw is a 20th-century English chamber opera composed by Benjamin Britten with a libretto by Myfanwy Piper, "wife of the artist John Piper, who had been a friend of the composer since 1935 and had provided designs for several of the operas". The libretto is based on the novella "The Turn of the Screw" by Henry James. The opera was commissioned by the Venice Biennale and given its world premiere on 14 September 1954, at the Teatro La Fenice, Venice. The original recording was made during that year, with the composer conducting. Context_4 : Dramatic structure (also called Freytag's pyramid) is the structure of a dramatic work such as a play or film. Many scholars have analyzed dramatic structure, beginning with Aristotle in his "Poetics" (c. 335 BCE). This article focuses primarily on Gustav Freytag's analysis of ancient Greek and Shakespearean drama. Context_5 : The Turn of the Screw (also known as Ghost Story: The Turn of the Screw) is a British television film based on Henry James's 1898 ghost story of the same name. Commissioned and produced by the BBC, it was first broadcast on 30 December 2009, on BBC One. The novella was adapted for the screen by Sandy Welch, and the film was directed by Tim Fywell. Although generally true to the tone and story of James's work, the film is set in the 1920sin contrast to the original 1840s settingand accentuates sexual elements that some theorists have identified in the novella. The film's story is told in flashbacks during consultations between the institutionalised Ann (Michelle Dockery) and Dr Fisher (Dan Stevens). Ann tells how she was hired by an aristocrat (Mark Umbers) to care for the orphans Miles (Josef Lindsay) and Flora (Eva Sayer). She is met at the children's home, Bly, by Mrs Grose (Sue Johnston), the housekeeper. Ann soon begins to see unknown figures around the manor, and seeks an explanation. Context_6 : Dynamic hip screw (DHS) or Sliding Screw Fixation is a type of orthopaedic implant designed for fixation of certain types of hip fractures which allows controlled dynamic sliding of the femoral head component along the construct. One common use is internal fixation of intertrochanteric fractures of the femur, which are common in older osteoporotic patients. There are 3 components of a dynamic hip screw, including a lag screw (inserted into the neck of the femur), a sideplate and four cortical screws (fixated into the proximal femoral shaft). The idea behind the dynamic compression is that the femoral head component is allowed to move along one plane; since bone responds to dynamic stresses, the native femur may undergo primary healing: cells join along boundaries, resulting in a robust joint requiring no remodeling. Context_7 : A set screw is a type of screw generally used to secure an object within or against another object, normally not using a nut (see bolts compared with screws). The most common examples are securing a pulley or gear to a shaft. Set screws are usually headless (also called "blind"), meaning that the screw is fully threaded and has no head projecting past the major diameter of the screw thread. If a set screw has a head, the thread will extend all the way to the head (whereas a bolt might have an unthreaded shank between the head and thread). A blind set screw (known in the UK as a grub screw, quite possibly from its figurative resemblance to a soil-dwelling grub) is almost always driven with an internal-wrenching drive, such as a hex socket (Allen), star (Torx), square socket (Robertson), or slot. The set screw passes through a threaded hole in the outer object and is tightened against the inner object to prevent it from moving relative to the outer object. It exerts compressional or clamping force through the bottom tip that projects through the hole. Context_8 : Mask (sometimes The Mask) is a 1985 album by the Greek electronic music composer Vangelis. It was the last album he produced while living in London, and also the last he produced for the Polydor label. It is dramatic work in six movements, with somewhat dark mood and classical style which branches into ethnic styles. The album reached #69 position in the UK album charts. Context_9 : Sadko (Russian: , the name of the main character) is an opera in seven scenes by Nikolai Rimsky-Korsakov. The libretto was written by the composer, with assistance from Vladimir Belsky, Vladimir Stasov, and others. Rimsky-Korsakov was first inspired by the Bylina of Sadko in 1867, when he completed a tone poem on the subject, his Op. 5. After finishing his second revision of this work in 1891, he decided to turn it into a dramatic work. Context_10 : The GP-5 gas mask (Russian: -5 , "Grazhdanskii Protivogaz-5" ) is a Soviet-made single-filter gas mask. It was issued to the Soviet population starting in 1962; production ended in 1989. It is a lightweight mask, weighing 1.09kg (2.42lbs). It can operate in all weather and withstand temperatures from 40 degrees (Celsius and Fahrenheit) to 114 C . The GP-5 also comes with sealed glass eye pieces. They were originally made to protect the wearer from radioactive fallout during the Cold War and were distributed to most fallout shelters. They have been tested in Poland to see if they have NBC protective capabilities. It was concluded that the mask will last in an NBC situation for 24 hours. They are a favorite of gas mask collectors because they are common and have the "old" circular eyepieces like masks used in World War II and the "helmet" type masks. The GP-5 kit consists of SHM-62 face piece, GP-5 filter, bag and anti fogging lenses. the GP-5 kit can be also completed SHM-62u SHMP SHM-62mu face pieces. fact_1 : The Mask of Orpheus is an opera with music by Harrison Birtwistle and a libretto by Peter Zinovieff. fact_2 : The Turn of the Screw is a 20th-century English chamber opera composed by Benjamin Britten with a libretto by Myfanwy Piper, "wife of the artist John Piper, who had been a friend of the composer since 1935 and had provided designs for several of the operas".
