NCSIST Teng Yun. The Teng Yun (, “Cloud Rider”) is a UAV under development by the National Chung-Shan Institute of Science and Technology  (NCSIST) of Taiwan. It was said to be able to carry armaments to conduct combat missions.

Overview

The Teng Yun is a medium UCAV with a resemblance to the American MQ-9 Reaper. The 2019 defense budget allocated funds to build a significant number of Teng Yun systems.

Development
A prototype was exhibited at the Taipei Aerospace & Defense Technology Exhibition in 2015. An updated model with underwing hard points was exhibited in 2017.

In 2018 a Teng Yun being tested was observed by residents of Taitung. Taiwan’s Air Force declined to procure the platform over concerns about the reliability of its electronic systems. In response NCSIST introduced an improved model with enhanced thrust, greater-range, more payloads, an enhanced flight control system, and a triple-backup power system. NCSIST has announced that the improved the version of the Teng Yun would commence testing in Jan. 2020 with combat testing to be conducted in 2021. Pictures of the improved version first surfaced in 2020. The improved version has a wider fuselage, a larger air intake, and more closely resembles the MQ-9 Reaper. In June 2022 one of the improved variants, dubbed the Teng Yun 2, completed a ten hour test flight.

Incidents
In February 2021 one prototype of the first generation Teng Yun crashed in Taitung Forest Park during a test flight.

Circuit breaker analyzer. A circuit breaker analyzer is an instrument that measures the parameters of a circuit breaker.

In 1984, Megger patented a digital circuit breaker analyzer, controlled by a microprocessor. in 2020 few companies develop software to control circuit breaker analyzers from different devices such as computers, tablet computer, smartphones and others.

The following tests can be carried out on the circuit breaker: mechanical, thermal, dielectric, short-circuit.

The analyzer operates the circuit breaker under fault current conditions. After finishing the test of the breaker, the system measures currents, voltages and other main parameters of the breaker and through a set algorithm diagnoses the condition of the device under different conditions. The final result of the analysis give information about trip times, essential synchronism of the poles in the different operations of the circuit breaker.

Walter Currie (educator). Walter Currie (1922-2014) was an educator and public advocate. He was part of the movement after the Second World War advocating for Indigenous educational reform at the local and national level in Canada.

History
Walter Currie was born in Chatham, Ontario in 1922. The son of William and Clara Currie, he was a non-status Indian of Potowatomi and Ojibwe descent. He served three years in the Royal Canadian Air Force during World War Two, and later studied engineering at the University of Toronto, before leaving his studies early to support his young family.  He would later complete his degree at the University of Windsor and go on to complete his teacher's certificate at London's Teachers College. He was a school teacher in Kitchener and principal at Danesbury Public School in North York Township between 1953 and 1968. In 1966 he was appointed to head an Ontario Governmental committee on the "Indian in the City." He later became a superintendent with the Ontario Department of Education with responsibilities Indian and northern schools from 1968 to 1971.  During this period, he was active in local and provincial affairs, and s quoted in major newspapers on topics related to Indigenous education, discrimination against Indigenous people in urban areas, lack of representation of Indigenous history, language and culture in the media and in school curriculum, as well as the "social ills" of television.

Currie also served as president of the Indian-Eskimo Association of Canada and was the first chairman of the Toronto Indian Friendship Centre from 1969 to 1971. He was one of the first two members of Ontario's Human Rights Commission, and served from 1972 to 1974. In July 1971, Currie was appointed as chair of Native Studies at Trent University, where he served a term to 1975. In this role, Currie continued to be active on provincial and national Indigenous issues, particularly educational reform, repatriation of cultural artifacts, and, entrepreneurial opportunities on- and off-reserve for Indigenous business people.

1973 Sólheimasandur Douglas DC-3 crash. On 21 November 1973, a Douglas C-117D transport aircraft operated by the United States Navy crashed onto  beach in southern Iceland during severe icing conditions. All seven crewmembers on board survived the accident, and the aircraft was written off. The main fuselage wreckage has remained relatively intact since the accident, leading to the crash site becoming a tourist destination.

Accident
The aircraft involved in the accident was flying from Hofn Hornafjördur Airport to Naval Air Station Keflavik, after delivering supplies for the radar station at Stokksnes. En route the aircraft encountered severe icing and the crew were forced to land on a frozen river at Sólheimasandur. All 7 crew members survived and were rescued by helicopter, but the aircraft was written off ('surveyed' in US Navy parlance). The unsalvaged remains of the aircraft were left at the scene.

Aircraft
The aircraft, serial number 17171, was designated C-117D and was based on the Super DC-3, first flown in 1944. This R4D-8 was built as an R4D-5 (msn 12554) and converted to R4D-8 (msn 43309) in November 1951. All R4D-8 aircraft still extant were re-designated as C-117D in the tri-service designation system introduced from 18 September 1962.

Tourist site
As of 2024, the fuselage of the aircraft remains relatively intact, and the site has become a popular tourist destination. The wreck has accumulated superficial damage from graffiti, gunfire, and tourists over the years. Tours to the site are available, and the trek back and forth takes about two to three hours.

In January 2020, two Chinese tourists died of hypothermia near the wreckage after getting caught in a storm. A month later, search and rescue units had to rescue several tourists who had ignored a warning from the police to not trek to the wreckage due to deteriorating weather in the area.

Popular culture 
The crash site of the DC-3 was featured in the music video of Justin Bieber's 2015 song I'll Show You.
American musician George Hirsch's 2016 album Hijrah used an image of the Sólheimasandur crash as its cover.

The show Top Gear America featured in the episode "Viking Trucks" while in Iceland.

 A music video of song named Gerua, from the Indian film "Dilwale" was shot at this site, in which lead actors Shah Rukh Khan and Kajol are seen standing on the wreckage. The site gained popularity among Indian tourists after the release of the song.

The site was also featured in the music video "Let Me In", an orchestral ballad song that introduced the member HaSeul of the Korean girl group Loona.

 The site is featured in the Netflix sci-fi drama Katla.

 The site is featured in start of season 12 of the Dutch reality TV game show Wie is de Mol?

Dichlorodiethyl sulfone. Dichlorodiethyl sulfone (or mustard sulfone) is an oxidation product of mustard gas. It has the formula (ClCH2CH2)2SO2. Although it is irritating to the eyes, it is not nearly as bad as mustard gas (dichlorodiethyl sulfide).

Structure
The all-trans arrangement is predicted by Hartree-Fock computational methods to be the most stable conformer.

Reactions
When refluxed with aqueous sodium hydroxide, oxygen replaces the chlorine, and an 1,4-oxathiane ring is formed, p-oxathiane-4,4-dioxide. When treated with sodium carbonate, a weaker base, bis-(hydroxyethyl)sulfone is the major product formed. In comparison the dehydrochlorination of the sulfoxide is much slower.

1,4-Oxathiane. 1,4-Oxathiane is a heterocyclic compound containing one oxygen atom and one sulfur atom at opposite corners of a saturated six-membered ring. By systematic numbering, the oxygen atom is position number 1, sulfur is number 4, and positions 2, 3, 5, and 6 are carbon atoms.

Production
1,4-Oxathiane can be produced from low cost ingredients by heating ethylene glycol or ethylene oxide with hydrogen sulfide. Alternate ways are to dehydrate bis(hydroxy ethyl) sulfide by heating with potassium hydrogen sulfate. These reactions also form 1,4-dithiane as a byproduct.

The original 1912 preparation of 1,4-oxathiane involved iodoethyl ether with potassium sulfide in alcohol. A similar method used 2-chloroethyl ether.

Reactions
The sulfur atom in 1,4-oxathiane can undergo reaction as other substituted sulfides can. It can be oxidised to a sulfoxide with calcium hypochlorite or sodium periodate, or continuing to a sulfone.

It can react with ammonia to form diimines.

With elemental chlorine below 0 °C, 3-chloro-1,4-oxathiane is formed. Above 0 °C, 2,3-dichloro-1,4-oxathiane results and further chlorination yields 2,3,5,6-tetrachloro-1,4-oxathiane.

With hydrofluoric acid, 1,4-oxathiane is undergoes electrophilic fluorination to yield perfluoro-1,4-oxathiane: all eight hydrogen atoms are replaced with fluorine substituents, and also four fluorine atoms are attached to the sulfur atom.

With elemental bromine in ether, an oxathianium salt is formed. In this an extra bromine atom bonds to the sulfur atom which gets a positive charge. To balance this, a bromide ion forms to make up a salt. Similarly iodine in acetic acid reacts to make 4-iodo-1,4-oxathianium iodide. Heating 1,4-oxathiane with ethyl iodide yields 4-ethyl-1,4-oxathianium iodide.
