πŸ”— Inco Superstack

πŸ”— Canada

The Inco Superstack in Sudbury, Ontario, with a height of 381 metres (1,250Β ft), is the tallest chimney in Canada and the Western hemisphere, and the second tallest freestanding chimney in the world after the GRES-2 Power Station in Kazakhstan. It is also the second tallest freestanding structure of any type in Canada, behind the CN Tower but ahead of First Canadian Place. It is the 51st tallest freestanding structure in the world. The Superstack is located on top of the largest nickel smelting operation in the world at Vale's Copper Cliff processing facility in the city of Greater Sudbury.

In 2018, Vale announced that the stack would be decommissioned and dismantled beginning in 2020. Two new, smaller stacks were constructed under the company's Clean Atmospheric Emissions Reduction Project. In July 2020, Vale announced that the Superstack had been officially taken out of service, but would remain operational in standby mode for two more months as a backup in the event of a malfunction in the new system, following which the dismantling of the Superstack would begin. As of August 2021, however, Vale has not yet announced the awarding of a demolition contract on the Superstack, and it remains unknown when demolition will actually begin.

In addition to further reducing sulphur dioxide emissions by 85 per cent, the decommissioning of the stack is expected to cut the complex's natural gas consumption in half.

πŸ”— Types of Prostitution in Modern Japan

πŸ”— Sexology and sexuality πŸ”— Japan πŸ”— Japan/History πŸ”— Japan/Culture πŸ”— Japan/Law and government πŸ”— Gender Studies πŸ”— Sexology and sexuality/Sex work

Prostitution in modern Japan, as defined under Japanese law, is the illegal practice of sexual intercourse with an 'unspecified' (unacquainted) person in exchange for monetary compensation, which was criminalised in 1956 by the introduction of article 3 of the Anti-Prostitution Law (ε£²ζ˜₯ι˜²ζ­’ζ³•, Baishun bōshi hō). However, the definition of prostitution made illegal under this law is strictly limited to sexual intercourse with an 'unspecified person', and does not criminalise the sale of numerous other acts performed by sex workers in exchange for compensation, such as oral sex, anal sex, mammary intercourse, and other non-coital sex acts; the Businesses Affecting Public Morals Regulation Law of 1948 (ι’¨δΏ—ε–Άζ₯­ε–締法, FΕ«zoku eigyō torishimari hō), also known as the "Law to Regulate Adult Entertainment Businesses", amended in 1985, 1999 and 2005, regulates these businesses, making only one definition of prostitution in Japan illegal.

Following the criminalisation of payment for sexual intercourse, the sex industry in Japan has developed into a number of varied businesses and offering services not prohibited under Japanese law. These fall into a number of categories known by various euphemistic names, such as soaplands, fashion health shops, and pink salons, with the term "health" commonly being a euphemism for sexual services. These businesses typically operate out of physical premises, either with their own employees or freelancers such as call girls, who may operate via Internet dating sites known as deai sites (Internet dating sites) or via delivery health services.

πŸ”— Continuation-Passing Style

πŸ”— Computing πŸ”— Computer science

In functional programming, continuation-passing style (CPS) is a style of programming in which control is passed explicitly in the form of a continuation. This is contrasted with direct style, which is the usual style of programming. Gerald Jay Sussman and Guy L. Steele, Jr. coined the phrase in AI Memo 349 (1975), which sets out the first version of the Scheme programming language.John C. Reynolds gives a detailed account of the numerous discoveries of continuations.

A function written in continuation-passing style takes an extra argument: an explicit "continuation"; i.e., a function of one argument. When the CPS function has computed its result value, it "returns" it by calling the continuation function with this value as the argument. That means that when invoking a CPS function, the calling function is required to supply a procedure to be invoked with the subroutine's "return" value. Expressing code in this form makes a number of things explicit which are implicit in direct style. These include: procedure returns, which become apparent as calls to a continuation; intermediate values, which are all given names; order of argument evaluation, which is made explicit; and tail calls, which simply call a procedure with the same continuation, unmodified, that was passed to the caller.

Programs can be automatically transformed from direct style to CPS. Functional and logic compilers often use CPS as an intermediate representation where a compiler for an imperative or procedural programming language would use static single assignment form (SSA). SSA is formally equivalent to a subset of CPS (excluding non-local control flow, which does not occur when CPS is used as intermediate representation). Functional compilers can also use A-normal form (ANF) (but only for languages requiring eager evaluation), rather than with 'thunks' (described in the examples below) in CPS. CPS is used more frequently by compilers than by programmers as a local or global style.

πŸ”— St. Cuthbert's Beads

πŸ”— Palaeontology πŸ”— Animals

St. Cuthbert's beads (or Cuddy's beads) are fossilised portions of the "stems" of crinoids from the Carboniferous period. Crinoids are a kind of marine echinoderm which are still extant, and which are sometimes known as "sea lilies". These bead-like fossils are washed out onto the beach and in medieval Northumberland were strung together as necklaces or rosaries, and became associated with St Cuthbert.

In other parts of England, circular crinoid columnals were known as "fairy money." Pentagonal crinoid columnals were known as "star stones", and moulds of the stems left impressions which were known as screwstones. In Germany, the columnals were known as Bonifatius pfennige (St Boniface's pennies) and in America they are known as Indian beads.

πŸ”— Athletics at the 1904 Summer Olympics: Men's Marathon

πŸ”— Olympics πŸ”— Athletics

The men's marathon at the 1904 Summer Olympics in St. Louis, United States, took place on August 30 of that year, over a distance of 24.85Β miles (40Β km).

The race was run during the hottest part of the day on dusty country roads with minimal water supply; while thirty-two athletes representing four nations competed, only 14 managed to complete the race, which was a bizarre affair due to poor organization and officiating. While Fred Lorz was greeted as the apparent winner, he was later disqualified as he had hitched a ride in a car for part of the race. The actual winner, Thomas Hicks, was near collapse and hallucinating by the end of the race, a side effect of being administered brandy, raw eggs, and strychnine by his trainers. The fourth-place finisher, AndarΓ­n Carvajal, took a nap during the race after eating spoiled apples.

πŸ”— United States πŸ”— Nevada πŸ”— Micronations

The Republic of Molossia, also known as Molossia, is a micronation claiming sovereignty over 1.28 acres of land near Dayton, Nevada. The micronation has not received recognition from any of the member states of the United Nations. It was founded by Kevin Baugh. On April 16, 2016, Baugh hosted a tour of Molossia, sponsored by the website Atlas Obscura. He continues to pay property taxes on the land to Storey County (the recognized local government), although he calls it "foreign aid". He has stated "We all want to think we have our own country, but you know the U.S. is a lot bigger".

πŸ”— Project Highwater

πŸ”— Spaceflight

Project Highwater was an experiment carried out as part of two of the test flights of NASA's Saturn I launch vehicle (using battleship upper stages), successfully launched into a sub-orbital trajectory from Cape Canaveral, Florida. The Highwater experiment sought to determine the effect of a large volume of water suddenly released into the ionosphere. The project answered questions about the effect of the diffusion of propellants in the event that a rocket was destroyed at high altitude.

The first flight, SA-2, took place on April 25, 1962. After the flight test of the rocket was complete and first stage shutdown occurred, explosive charges on the dummy upper stages destroyed the rocket and released 23,000 US gallons (87,000Β L) of ballast water weighing 95 short tons (86,000Β kg) into the upper atmosphere at an altitude of 65 miles (105Β km), eventually reaching an apex of 90 miles (145Β km).

The second flight, SA-3, launched on November 16, 1962, and involved the same payload. The ballast water was explosively released at the flight's peak altitude of 104 miles (167Β km). For both of these experiments, the resulting ice clouds expanded to several miles in diameter and lightning-like radio disturbances were recorded.
