Cylinder (engine)

In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which provide seals for compression and the lubricating oil; the piston rings do not touch the cylinder walls, instead they ride on a thin layer of lubricating oil. The cylinder in a steam engine is made pressure-tight with a piston. Cylinders were cast in cast iron and in steel; the cylinder casting can include other features such as mounting feet. The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air-cooled engine, the walls of the cylinders are exposed to the airflow, to provide the primary method of cooling to the engine. Most air-cooled engines have cooling fins on the cylinders and each cylinder has a separate case in order to maximise the surface area available for cooling.

For motorcycle engines, a "reverse cylinder engine" is where the intake ports are on the front side of each cylinder, the exhaust ports are on the rear side of each cylinder. Cylinder liners are thin metal cylinder-shaped parts, inserted into the engine block to form the inner wall of the cylinder. Alternatively, an engine can be'sleeveless', where the cylinder walls are formed by the engine block with a wear-resistant coating, such as Nikasil or plasma-sprayed bores. During use, the cylinder liner is subject to wear from the rubbing action of the piston rings and piston skirt; this wear is minimized by the thin oil film which coats the cylinder walls and by a layer of glaze which forms as the engine is run-in. On some engines, the cylinder liner is replaceable, in case it becomes damaged. On engines without replaceable sleeves, the cylinder can sometimes be repaired by boring out the existing liner to produce a new smooth and round surface. Another repair technique is'sleeving' the cylinder— boring it and installing a sleeve in the extra space created by the boring.

Most engines use'dry liners', where the liner is surrounded by the engine block and does not make contact with the coolant. However, cylinders with'wet liners' are used in some water-cooled engines French designs; the wet liners are formed separately from the main casting so that liquid coolant is free to flow around their outsides. The advantage of wet liners is better cooling and a more temperature distribution, however this design reduces the rigidity of the engine.

2017–18 New Orleans Pelicans season

The 2017–18 New Orleans Pelicans season was the 16th season of the New Orleans Pelicans franchise in the National Basketball Association. The Pelicans were coached by Alvin Gentry in his third year as head coach, they played their home games at the Smoothie King Center as members of the Western Conference's Southwest Division. The team's second-leading scorer, DeMarcus Cousins, suffered a season-ending Achilles tendon injury during his subsequent final game as a Pelican on January 26, 2018, missed the remainder of the season; that led to Cousins' decision to controversially join the Golden State Warriors the following season. Cousins signed with the Warriors despite speculation he would join the Los Angeles Lakers or the Washington Wizards to reunite with former Kentucky Wildcats teammate John Wall. Despite losing Cousins, the Pelicans clinched their first playoff berth since 2015 with a win over the Los Angeles Clippers on April 9, 2018, they finished the season 48–34 to finish in second place in the Southwest Division.

In the Playoffs, the Pelicans faced off against the third-seeded Portland Trail Blazers in the First Round. On April 14, 2018, the Pelicans won the first game in the First Round playoff series which marked the franchise's first playoff game win since the 2011 playoffs' First Round series against the Los Angeles Lakers. On April 21, the Pelicans completed the playoff series sweep over the Trail Blazers, marking the franchise's first series win since 2008, it marked the first playoff series sweep in franchise history, the first time that a team seeded sixth or lower had swept a First Round series since the NBA had expanded the First Round to a best-of-seven series. They advanced to the Conference Semifinals to face the second-seeded and eventual NBA champion Golden State Warriors, the team that swept them in the First Round of the 2015 playoffs; the Pelicans were eliminated from the playoffs. As of 2019, this marked the last time. Prior to the NBA draft, the Pelicans had only one second round pick, having traded their first round pick, rookie Buddy Hield, Tyreke Evans, Langston Galloway, the Philadelphia 76ers' original second round pick to the Sacramento Kings in a blockbuster trade for star center DeMarcus Cousins and Omri Casspi.

On June 21, 2017, the Pelicans acquired the Washington Wizards' second round pick in exchange for guard Tim Frazier. As a result, the Pelicans entered draft night with no first round picks. On the night of the draft, the Pelicans traded away their second round pick and cash considerations to the Charlotte Hornets in exchange for the Hornets' second round pick. With that pick, the Pelicans selected Duke point guard Frank Jackson. With the No. 52 overall pick, the Pelicans selected Xavier point guard Edmond Sumner and traded him to the Indiana Pacers for cash considerations

Behrend sequence

In number theory, a Behrend sequence is an integer sequence whose multiples include all integers. The sequences are named after Felix Behrend. If A is a sequence of integers greater than one, if M denotes the set of positive integer multiples of members of A A is a Behrend sequence if M has natural density one; this means that the proportion of the integers from 1 to n that belong to M converges, in the limit of large n, to one. The prime numbers form a Behrend sequence, because every integer greater than one is a multiple of a prime number. More a subsequence A of the prime numbers forms a Behrend sequence if and only if the sum of reciprocals of A diverges; the semiprimes, the products of two prime numbers form a Behrend sequence. The only integers that are not multiples of a semiprime are the prime powers, but as the prime powers have density zero, their complement, the multiples of the semiprimes, have density one. The problem of characterizing these sequence was described as "very difficult" by Paul Erdős in 1979.

These sequences were named "Behrend sequences" in 1990 by Richard R. Hall, with a definition using logarithmic density in place of natural density. Hall chose their name in honor of Felix Behrend, who proved that for a Behrend sequence A, the sum of reciprocals of A must diverge. Hall and Gérald Tenenbaum used natural density to define Behrend sequences in place of logarithmic density; this variation in definitions makes no difference in which sequences are Behrend sequences, because the Davenport–Erdős theorem shows that, for sets of multiples, having natural density one and having logarithmic density one are equivalent. When A is a Behrend sequence, one may derive another Behrend sequence by omitting from A any finite number of elements; every Behrend sequence may be decomposed into the disjoint union of infinitely many Behrend sequences

Freedom (2016 film)

Freedom is a 2016 Ugandan drama film set in the pre-NRA war times and details the despicable abuse suffered by an unlucky Amelia at the hands of her adoptive father. The film was produced by screenplay by both Mulindwa and Nisha Kalema. After its release, the film dominated nominations and awards at the 2016 Uganda Film Festival Awards with nine nominations and six wins including Best Feature Film, Best Director, Best Actor and Best Actress. British producer and religious minister George Hargreaves premiered Freedom on stage in Europe in August 2017, it was staged at the Edinburgh Fringe Festival in Scotland and the Bernie Grant Arts Centre in London between August 15-26th that same year. Nisha Kalema, the film's screenwriter lost her screen writing credits on the promotional posters, film’s DVD and theatre release, hence falling out with the producers of the film, she was however credited on IMDb for screenplay.

KUOW-FM is a National Public Radio member station in Seattle, Washington. It is the larger of the three full-fledged NPR member stations in the Seattle/Tacoma media market, with two Tacoma-based stations, KNKX and KVTI being the others, it is a service of the University of Washington, but is operated by KUOW Puget Sound Public Radio, a nonprofit community organization. Studios are located on University Way in Seattle's University District, while the transmitter is on Capitol Hill. KUOW is carried on the following satellite and broadcast translator stations to improve reception of the station: KQOW 90.3 FM Bellingham KUOW 1340 AM Tumwater/Olympia KUOW's site states its mission as, "to create and serve an informed public, one challenged and invigorated by an understanding and appreciation of events and cultures."KUOW went on the air in 1952 on 90.5 FM. Its transmitter was on the University of Washington campus atop the Administration Building, now Gerberding Hall. In 1958, Dorothy Stimson Bullitt moved KING-FM to 98.1 and gifted KING's 94.9 FM transmitter and antenna to the Edison Vocational School.

That same year, KUOW started using the 94.9 FM transmitter operated by Edison. KUOW is one of the few public radio stations in the United States on a frequency outside of the reserved band. For years, it served as a training ground for UW students to learn about broadcasting. Programming consisted of classical music, classroom lectures, local news, Washington Huskies sports. From 1954 until 1987, KUOW was a sister station to educational television outlet KCTS-TV. In the 1960s, however, KUOW began adding more news programming, it was a charter member of NPR in 1970. In 1992, it changed format from music to news and information, in 1999 it moved off campus to its current location on University Way. In 1999, UW outsourced the station's operation to Puget Sound Public Radio; the station operates two repeaters in the Puget Sound region in Bellingham on KQOW FM 90.3, in Olympia on KUOW AM 1340, on the Internet. KUOW-FM broadcasts in HD. On March 7, 2018, KUOW made the decision to discontinue the HD2, HD3, HD4 subchannels.

"KUOW2" continues to be transmitted on translator K214EW 90.7/KQOW-HD2 in Bellingham, while KUOW Jazz was discontinued. The main analog signal continues to be simulcast on HD1. KUOW's 2008 annual report states that the station served an average of 375,800 listeners each week in fiscal year 2008; these listeners averaged eight and a quarter hours of listening per week to total more than 3 million weekly listener hours. In the same year, KUOW ranked second among all radio stations in the Seattle Metro market, with a 4.8% share of the market's radio audience. KUOW's 2010 direct support totaled $10,134,882, its sources were: 60% individuals 29% corporate 9% government 2% other KUOW produces several programs, most of which are concerned with local news and events: The Record: Hosted by Bill Radke. This midday news magazine covers a mix of local and international news every weekday. Week In Review: Hosted by Bill Radke; the Friday edition of The Record. Speaker's Forum: Speaker's Forum airs speeches and presentations from a wide variety of specialties.

The Swing Years and Beyond: the program was hosted by Amanda Wilde from 2003 to 2017 when the program was ended. KUOW broadcast the Washington Talking Book and Braille Library's Evergreen Radio Reading Service to blind and handicapped listeners on its 67kHz subcarrier, until the service's closure on August 15, 2014. KUOW was one of three major FM stations in Washington to do so. However, this required a special FM radio capable of receiving such broadcasts.
