Jenůfa    (Její pastorkyňa, "Her Stepdaughter" in Czech) is an opera in three acts by Leoš Janáček to a Czech libretto by the composer, based on the play "Její pastorkyňa" by Gabriela Preissová.
 It was first performed at the Brno Theater, Brno, 21 January 1904.
 It was written between 1896 and 1902, and counts among the first operas written in prose.
Didone abbandonata ("Dido Abandoned") was an opera in three acts composed by Tomaso Albinoni.
 Albinoni's music (now lost) was set to Pietro Metastasio's libretto, "Didone abbandonata", which was in turn based on the story of Dido and Aeneas from the fourth book of Virgil's "Aeneid".
 The opera premiered on 26 December 1724 at the Teatro San Cassiano in Venice and was the first time that an opera based on a Metastasio libretto was performed in Venice.
Loretta Di Franco is an American operatic soprano who is chiefly known for her more than 900 performances at the Metropolitan Opera from 1961-1995.
 Originally a member of the Met's opera chorus, she eventually was promoted to singing small comprimario roles beginning with one of the pages in Wagner's "Tannhäuser" and the peasant girl in "The Marriage of Figaro" in 1961.
 She went on to win the Metropolitan Opera National Council Auditions in 1965 which led to her first substantial role, Chloe in "The Queen of Spades".
 She continued to appear annually at the Met for the next 30 years, performing both leading and supporting roles.
 Some of the parts she performed at the Met included Annina in "La traviata", both the Aunt and Barena in Janáček's "Jenůfa", Barbarina and Marcellina in "The Marriage of Figaro", Berta in "The Barber of Seville", Countess Ceprano in "Rigoletto", the Dew Fairy and the Sandman in "Hansel and Gretel", Feklusa in "Káťa Kabanová", the First Lady in "The Magic Flute", the Flower Seller in Britten's "Death in Venice", Frasquita in "Carmen", Gerhilde in "Die Walküre", Giannetta in "L'elisir d'amore", Helen in "Mourning Becomes Electra", Ines in "Il trovatore", Jouvenot in "Adriana Lecouvreur", Kate Pinkerton in "Madama Butterfly", Laura in "Luisa Miller", Lauretta in "Gianni Schichi", Lisa in "La sonnambula", Marianne in "Der Rosenkavalier", Marthe in "Faust", Musetta in "La bohème", Oscar in "Un ballo in maschera", Samaritana in "Francesca da Rimini", Woglinde in both "Das Rheingold" and "Götterdämmerung", Xenia in "Boris Godunov", Zerlina in "Don Giovanni", and title role in "Lucia di Lammermoor".
 In 1991 she created the role of the Woman with Child in the world premiere of John Corigliano's "The Ghosts of Versailles".
A screw drive is a system used to turn a screw.
 At a minimum, it is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it.
 Usually, it also involves a mating tool, such as a screwdriver, that is used to turn it.
 The following heads are categorized based on commonality, with some of the less-common drives being classified as "tamper-resistant".
A differential screw is a mechanism used for making small, precise adjustments to the spacing between two objects (such as in focusing a microscope, moving the anvils of a micrometer, or positioning optics).
 A differential screw uses a spindle with two screw threads of differing leads (aka thread pitch), and possibly opposite handedness, on which two nuts move.
 As the spindle rotates, the space between the nuts changes based on the difference between the threads.
 These mechanisms allow extremely small adjustments using commonly available screws.
 A differential screw mechanism using two nuts incurs higher friction and therefore requires more torque to turn than a simple, single lead screw with an equivalent pitch.
The crank machine was a device which turned a crank by hand which in turn forced four large cups or ladles through sand inside a drum, doing nothing useful.
 Male prisoners had to turn the handle 14,400 times a day, as registered on a dial.
 The warder could make the task harder by tightening an adjusting screw, hence the slang term "screw" for prison warder.
Cam out (or cam-out) is a process by which a screwdriver slips out of the head of a screw being driven once the torque required to turn the screw exceeds a certain amount.
 Repeatedly camming out damages the screw, and possibly also the screwdriver, and should normally be avoided.
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 1920s—in contrast to the original 1840s setting—and 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.
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.
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.
