Nuclear chain reaction

A nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series of these reactions. The specific nuclear reaction may be the fission of heavy isotopes; the nuclear chain reaction releases several million times more energy per reaction than any chemical reaction. Chemical chain reactions were first proposed by German chemist Max Bodenstein in 1913, were reasonably well understood before nuclear chain reactions were proposed, it was understood that chemical chain reactions were responsible for exponentially increasing rates in reactions, such as produced in chemical explosions. The concept of a nuclear chain reaction was first hypothesized by Hungarian scientist Leó Szilárd on September 12, 1933. Szilárd that morning had been reading in a London paper of an experiment in which protons from an accelerator had been used to split lithium-7 into alpha particles, the fact that much greater amounts of energy were produced by the reaction than the proton supplied.

Ernest Rutherford commented in the article that inefficiencies in the process precluded use of it for power generation. However, the neutron had been discovered in 1932, shortly before, as the product of a nuclear reaction. Szilárd, trained as an engineer and physicist, put the two nuclear experimental results together in his mind and realized that if a nuclear reaction produced neutrons, which caused further similar nuclear reactions, the process might be a self-perpetuating nuclear chain-reaction, spontaneously producing new isotopes and power without the need for protons or an accelerator. Szilárd, did not propose fission as the mechanism for his chain reaction, since the fission reaction was not yet discovered, or suspected. Instead, Szilárd proposed using mixtures of lighter known isotopes which produced neutrons in copious amounts, he filed a patent for his idea of a simple nuclear reactor the following year. In 1936, Szilárd attempted to create a chain reaction using beryllium and indium, but was unsuccessful.

Nuclear fission was discovered and proved by Otto Hahn and Fritz Strassmann in December 1938. A few months Frédéric Joliot, H. Von Halban and L. Kowarski in Paris searched for, discovered, neutron multiplication in uranium, proving that a nuclear chain reaction by this mechanism was indeed possible. On May 4, 1939, Joliot and Kowarski filed three patents; the first two described power production from a nuclear chain reaction, the last one called "Perfectionnement aux charges explosives" was the first patent for the atomic bomb and is filed as patent No. 445686 by the Caisse nationale de Recherche Scientifique. In parallel, Szilárd and Enrico Fermi in New York made the same analysis; this discovery prompted the letter from Szilárd and signed by Albert Einstein to President Franklin D. Roosevelt, warning of the possibility that Nazi Germany might be attempting to build an atomic bomb. On December 2, 1942, a team led by Fermi produced the first artificial self-sustaining nuclear chain reaction with the Chicago Pile-1 experimental reactor in a racquets court below the bleachers of Stagg Field at the University of Chicago.

Fermi's experiments at the University of Chicago were part of Arthur H. Compton's Metallurgical Laboratory of the Manhattan Project. In 1956, Paul Kuroda of the University of Arkansas postulated that a natural fission reactor may have once existed. Since nuclear chain reactions may only require natural materials, it was possible to have these chain reactions occur in the distant past when uranium-235 concentrations were higher than today, where there was the right combination of materials within the Earth's crust. Kuroda's prediction was verified with the discovery of evidence of natural self-sustaining nuclear chain reactions in the past at Oklo in Gabon, Africa, in September 1972. Fission chain reactions occur because of interactions between neutrons and fissile isotopes; the chain reaction requires both the release of neutrons from fissile isotopes undergoing nuclear fission and the subsequent absorption of some of these neutrons in fissile isotopes. When an atom undergoes nuclear fission, a few neutrons are ejected from the reaction.

These free neutrons will interact with the surrounding medium, if more fissile fuel is present, some may be absorbed and cause more fissions. Thus, the cycle repeats to give a reaction, self-sustaining. Nuclear power plants operate by controlling the rate at which nuclear reactions occur, on the other hand, nuclear weapons are engineered to produce a reaction, so fast and intense it cannot be controlled after it has started; when properly designed, this uncontrolled reaction will lead to an explosive energy release. Nuclear weapons employ high quality enriched fuel exceeding the critical size and geometry necessary in order to obtain an explosive chain reaction; the fuel for energy purposes, such as in a nuclear fission reactor, is different consisting of a low-enriched oxide material. When a fissile atom undergoes nuclear fission, it breaks into two or more fission fragments. Several free neutrons, gamma rays, neutrinos are emitted, a large amount of energy is released; the sum of the rest masses of the fission fragments and ejected neutrons is

The One with the Monkey

The One with the Monkey is the tenth episode of the NBC television series Friends. It is the tenth episode of the show's first season and was broadcast on December 15, 1994; this episode marks the first appearance of a monkey that Ross adopts to keep him company. Phoebe meets scientist David, though their relationship is short-lived, when David gets a grant to work in Minsk; the gang all make a no-date pact for their New Year's Eve party, though they all end up breaking it, with undesired consequences. In order to curb his loneliness after his divorce, Ross adopts a capuchin monkey named Marcel. Things start off on rocky footing - Marcel seems rebellious and unwilling to listen to Ross. However, Chandler bonds with him immediately. With New Year's fast approaching, Chandler proposes that the gang make a no-date pact and have dinner together on New Year's Eve, which everyone agrees to. Phoebe sings 13 new songs - all of them about her mother's suicide. During her set, she is interrupted by two scientists arguing over her performance.

She goes to confront them, finds out that one of them - David - thinks that she is the most beautiful woman he has seen though his partner, begs to differ. Phoebe and David begin dating and she asks Chandler for permission to break the no-date pact for New Year's, he agrees as he has asked Janice, having snapped at the thought of being alone despite how annoying she is. As the days pass, Monica plans on bringing her ex-boyfriend Fun Bobby, Rachel learns that Paolo will catch an earlier flight back to the US from Italy for New Year's, Joey invites Sandy, a single mom he meets while working as one of Santa's elves at the mall; when Ross objects to all his friends breaking their no-date pact, Rachel suggests turning their New Year's dinner into a New Year's party to compensate so no one knows, with whom. Max arrives and tells Phoebe that he and David have gotten a grant to study in Minsk for three years, will be leaving on New Year's Day; when she goes to congratulate David, he and Max inform her that he has rejected the opportunity to go, wishing to stay in New York with her.

The six friends end up keeping their no-date pact after all: Ross arrives at the party with only Marcel. Paolo has missed his flight, Rachel gets attacked outside of the airport by a woman who thinks Rachel has stolen her cab. Max informs David that he is leaving for Minsk alone, Phoebe convinces him to go with him, telling him he cannot stay just for her. Fun Bobby is depressed because his grandfather has just died, makes the party more depressing. Sandy not only brings her kids to the party. Chandler tries to tell Janice that he only invited her for New Year's, but she gets upset at him and storms off. At midnight, Phoebe is too sad to kiss anyone, Rachel's lip was cut in the attack so she cannot kiss anyone, Monica does not feel like kissing anybody. Chandler demands someone kiss him anyway - so Joey obliges. Entertainment Weekly gave the episode a B, saying the episode introduces the monkey, "perhaps Friends' biggest blunder - forcing Schwimmer to do comedy opposite a simian is beneath him."

The episode "illustrates the writer' tendency to overplot", "and the multiple story lines never quite jell. Still, any ep that gives Phoebe center stage gets bumped up a grade."Sam Ashurst from Digital Spy ranked it #120 on their ranking of the 236 Friends episodes, called it a "strong, early episode". Telegraph & Argus wrote that the show stealer was Chandler's line "You don't have to face the horrible pressures of this holiday: desperate scramble to find anything with lips just so you can have someone to kiss when the ball drops!! Man, I'm talking loud!"Distractify ranked it the number one Friends Christmas episode. The One with the Monkey on IMDb "The One with the Monkey" at TV.com

FV Margiris

FV Margiris is the world's second largest fishing boat. It is a 9,500 GT super factory ship. In 2012, Seafish Tasmania brought the ship to Australia, she was authorized to catch a quota of 18,000 tonnes of jack mackerel and redbait along the southern shores of the country. After protests against her use by environmental and fishing industry groups, the Australian government passed legislation prohibiting the trawler from fishing in Australian waters for two years. For this reason, Seafish Tasmania subsequently sold its stake in the vessel to Dutch company Parlevliet & Van der Plas. On March 6, 2013, after six months moored in Australian waters, she left Port Lincoln, having reassumed her original name of Margiris. After leaving Australian waters, the vessel passed through Cook Strait, New Zealand on March 20, 2013, she was now owned by Atlantic High Sea Fishing Company. Margiris arrived in Port of Penco, Chile on April 7, 2013; the vessel steamed out of the bay to fish. The Super Trawler issue was subject to a court challenge in 2014 and an Australian Government scientific report published in late 2014.

Before and after this report there was reaffirmation that super trawlers over 130 metres, like Margiris, would not be permitted under Australia's environmental protection law, yet controversy continues in Australia about factory-fishing boats. In late October 2015, the Margiris was fishing off the North west coast of Ireland; the Irish naval service fisheries inspectors refused to board her at sea, due to adverse weather condition. She had departed the waters shortly. In November 2016, the Margiris entered Irish water; the ship had been active for a day when it was boarded by an Irish Naval Service fisheries inspection team.
