Although Aronson isolated this mycobacterium in 1926 from a fish, it was not until 1951 that it was found to be the cause of human disease by Linell and Norden. Large outbreaks of infection due to this atypical mycobacterium have been described in association with swimming. Infections related to swimming pools have now drastically fallen due to the improvements in the construction and maintenance of these facilities.The first case of M. marinum infection associated with a fish-tank ('fish-tank granuloma') was reported in 1962 by Swift and Cohen. M. marinum infection may be an occupational hazard for certain professions such as pet shop workers, but most infections occur in fish fanciers who keep an aquarium at home. Although infection may be caused by direct injury from the fish fins or bites, most are acquired during the handling of the aquariums such as cleaning or changing the water. Indirect infection has also been described related to a child’s bathing utensils that had been used to clean a fish tank. Due to an increased awareness of the disease and improved isolation methods, more and more cases are being recognized and reported worldwide.

Question: Besides being a danger for fish fanciers, what type of employees need to be cautious about M. marinum infection?
Answer: pet shop workers
Nathan Mayer's eldest son, Lionel de Rothschild (1808–1879), succeeded him as head of the London branch. Under Lionel, the bank financed the British government's 1875 purchase of Egypt's interest in the Suez Canal. The Rothschild bank also funded Cecil Rhodes in the development of the British South Africa Company. Leopold de Rothschild (1845–1917) administered Rhodes's estate after his death in 1902 and helped to set up the Rhodes Scholarship scheme at the University of Oxford. In 1873, de Rothschild Frères in France and N. M. Rothschild & Sons of London joined with other investors to acquire the Spanish government's money-losing Rio Tinto copper mines. The new owners restructured the company and turned it into a profitable business. By 1905, the Rothschild interest in Rio Tinto amounted to more than 30 percent. In 1887, the French and British Rothschild banking houses loaned money to, and invested in, the De Beers diamond mines in South Africa, becoming its largest shareholders.

Question: What adjective was used to characterize how successful the business was?
Answer: profitable
The second French branch was founded by Nathaniel de Rothschild (1812–1870). Born in London, he was the fourth child of the founder of the British branch of the family, Nathan Mayer Rothschild (1777–1836). In 1850 Nathaniel Rothschild moved to Paris to work with his uncle James Mayer Rothschild. In 1853 Nathaniel acquired Château Brane Mouton, a vineyard in Pauillac in the Gironde département.  Nathaniel Rothschild renamed the estate Château Mouton Rothschild, and it would become one of the best known labels in the world. In 1868, Nathaniel's uncle, James Mayer de Rothschild, acquired the neighbouring Château Lafite vineyard.

Question: When did Nathaniel get a grape growing farm?
Answer: 1853
An example of an observational study is one that explores the association between smoking and lung cancer. This type of study typically uses a survey to collect observations about the area of interest and then performs statistical analysis. In this case, the researchers would collect observations of both smokers and non-smokers, perhaps through a cohort study, and then look for the number of cases of lung cancer in each group. A case-control study is another type of observational study in which people with and without the outcome of interest (e.g. lung cancer) are invited to participate and their exposure histories are collected.

Question: What is the subject of one example of an observational study?
Answer: the association between smoking and lung cancer
An experimental study involves taking measurements of the system under study, manipulating the system, and then taking additional measurements using the same procedure to determine if the manipulation has modified the values of the measurements. In contrast, an observational study does not involve experimental manipulation. Instead, data are gathered and correlations between predictors and response are investigated.

Question: What is investigated?
Answer: correlations between predictors and response
Documenting and presenting the results of the study.Experiments on human behavior have special concerns. The famous Hawthorne study examined changes to the working environment at the Hawthorne plant of the Western Electric Company. The researchers were interested in determining whether increased illumination would increase the productivity of the assembly line workers. The researchers first measured the productivity in the plant, then modified the illumination in an area of the plant and checked if the changes in illumination affected productivity. It turned out that productivity indeed improved (under the experimental conditions). However, the study is heavily criticized today for errors in experimental procedures, specifically for the lack of a control group and blindness. The Hawthorne effect refers to finding that an outcome (in this case, worker productivity) changed due to observation itself. Those in the Hawthorne study became more productive not because the lighting was changed but because they were being observed.

Question: What sort of errors are criticized in the study?
Answer: experimental procedures, specifically for the lack of a control group and blindness
Statistical techniques are used in a wide range of types of scientific and social research, including: biostatistics,  computational biology,  computational sociology,  network biology,  social science,  sociology and  social research. Some fields of inquiry use applied statistics so extensively that they have specialized terminology. These disciplines include:

Question: What has specialized terminology?
Answer: Some fields of inquiry
Statistics is a branch of mathematics working with data collection, organization, analysis, interpretation and presentation. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied. Populations can be diverse groups of people or objects such as "all people living in a country" or "every atom composing a crystal". Statistics deals with every aspect of data, including the planning of data collection in terms of the design of surveys and experiments.

Question: What is a conventional way to start applying stastics to scientific problems?
Answer: statistical population or a statistical model
The concept of correlation is particularly noteworthy for the potential confusion it can cause. Statistical analysis of a data set often reveals that two variables (properties) of the population under consideration tend to vary together, as if they were connected. For example, a study of annual income that also looks at age of death might find that poor people tend to have shorter lives than affluent people. The two variables are said to be correlated; however, they may or may not be the cause of one another. The correlation phenomena could be caused by a third, previously unconsidered phenomenon, called a lurking variable or confounding variable. For this reason, there is no way to immediately infer the existence of a causal relationship between the two variables. (See Correlation does not imply causation.)

Question: What mathematical approach is employed in determining comparative similarities between a sample?
Answer: Statistical analysis
Attalus was a protector of the Greek cities of Anatolia and viewed himself as the champion of Greeks against barbarians. During his reign he established Pergamon as a considerable power in the Greek East. He died in 197 BC, shortly before the end of the second war, at the age of 72, having suffered an apparent stroke while addressing a Boeotian war council some months before. He and his wife were admired for their rearing of their four sons. He was succeeded as king by his son Eumenes II.

Question: When did he die?
Answer: 197 BC
Attalus won an important victory over the Galatians, newly arrived Celtic tribes from Thrace, who had been, for more than a generation, plundering and exacting tribute throughout most of Asia Minor without any serious check. This victory, celebrated by the triumphal monument at Pergamon (famous for its Dying Gaul) and the liberation from the Gallic "terror" which it represented, earned for Attalus the name of "Soter", and the title of "king". A courageous and capable general and loyal ally of Rome, he played a significant role in the first and second Macedonian Wars, waged against Philip V of Macedon. He conducted numerous naval operations, harassing Macedonian interests throughout the Aegean, winning honors, collecting spoils, and gaining for Pergamon possession of the Greek islands of Aegina during the first war, and Andros during the second, twice narrowly escaping capture at the hands of Philip.

Question: Who was the ruler of Macedon at the time?
Answer: Philip V
B. seeleyi (Haughton and Boonstra, 1929) is from the Tapinocephalus zone, Lower Beaufort Beds, Karoo basin, South Africa. This is a less common form. Boonstra, 1969, considered this a valid species of Bradysaurus and Lee, 1997, considers this animal a sister group to more advanced pareiasaurs. B. seelyi seems to be closely related to Nochelesaurus and Embrithosaurus. In contrast to the more numerous but similarly sized B. baini, the cheekbones were heavy and greatly enlarged. There were 19 or 20 pairs of strongly overlapping teeth on each jaw.

Question: What is different for baini?
Answer: the cheekbones were heavy and greatly enlarged
Bradysaurus is the only member of the subfamily Bradysaurinae. It is the most primitive known pareiasaur and can be considered a good ancestral type from which the others developed. Its large dimensions show that, even very early in their evolutionary history, these strange animals had already attained an optimal size. Even later, more advanced forms, like Scutosaurus, were no larger. The advantage of large size was to provide defense against predators and to maintain a stable body temperature (gigantothermy).

Question: When did the animals attain an optimal size?
Answer: early in their evolutionary history
He first started creating comics at the age of twelve, but that he had held an interest in drawing since at least six. He states that he still retains a habit of spending "an average of thirty-five dollars per week" on comics books. A fan of Dungeons & Dragons, Metzen cites the Dragonlance series of novels and Star Wars as the primary inspirations for his fantasy and science fiction creations, and names fantasy and comic book artists such as Walt Simonson and Keith Parkinson as his artistic inspirations.He defines his artistic style as having been "heavily influenced by Walt Simonson's and Jim Lee's pencilling styles for form" while preferring the "costuming, themes and general feel of Larry Elmore and Keith Parkinson's fantasy paintings". In addition to art, Metzen's interests include pop and rock music, the nightlife, and dirt bikes.On April 21, 2013, Metzen married his longtime girlfriend Kat Hunter, who was a licensing project manager at Blizzard Entertainment. They have three children.

Question: how much does he spend on comic books?
Answer: an average of thirty-five dollars per week
Born in Washington, D.C., Grover Furr graduated from McGill University in Montreal, Quebec, Canada, in 1965 with a BA in English. He received a Ph.D in Comparative literature from Princeton University in 1978. Since February 1970, he has been on the faculty at Montclair State University in New Jersey, where he specializes in medieval English literature.

Question: What did Grove Furr receive in 1978 from Princeton?
Answer: Ph.D in Comparative literature
Nanotechnology is often defined as the study of materials and devices with features on a scale below 100 nanometers.  DNA nanotechnology, specifically, is an example of bottom-up molecular self-assembly, in which molecular components spontaneously organize into stable structures; the particular form of these structures is induced by the physical and chemical properties of the components selected by the designers.  In DNA nanotechnology, the component materials are strands of nucleic acids such as DNA; these strands are often synthetic and are almost always used outside the context of a living cell. DNA is well-suited to nanoscale construction because the binding between two nucleic acid strands depends on simple base pairing rules which are well understood, and form the specific nanoscale structure of the nucleic acid double helix. These qualities make the assembly of nucleic acid structures easy to control through nucleic acid design.  This property is absent in other materials used in nanotechnology, including proteins, for which protein design is very difficult, and nanoparticles, which lack the capability for specific assembly on their own.The structure of a nucleic acid molecule consists of a sequence of nucleotides distinguished by which nucleobase they contain. In DNA, the four bases present are adenine (A), cytosine (C), guanine (G), and thymine (T).  Nucleic acids have the property that two molecules will only bind to each other to form a double helix if the two sequences are complementary, meaning that they form matching sequences of base pairs, with A only binding to T, and C only to G.  Because the formation of correctly matched base pairs is energetically favorable, nucleic acid strands are expected in most cases to bind to each other in the conformation that maximizes the number of correctly paired bases.  The sequences of bases in a system of strands thus determine the pattern of binding and the overall structure in an easily controllable way.  In DNA nanotechnology, the base sequences of strands are rationally designed by researchers so that the base pairing interactions cause the strands to assemble in the desired conformation.  While DNA is the dominant material used, structures incorporating other nucleic acids such as RNA and peptide nucleic acid (PNA) have also been constructed.

Question: What type of acids bind together to form DNA
Answer: nucleic
The sequences of the DNA strands making up a target structure are designed computationally, using molecular modeling and thermodynamic modeling software. The nucleic acids themselves are then synthesized using standard oligonucleotide synthesis methods, usually automated in an oligonucleotide synthesizer, and strands of custom sequences are commercially available.  Strands can be purified by denaturing gel electrophoresis if needed, and precise concentrations determined via any of several nucleic acid quantitation methods using ultraviolet absorbance spectroscopy.The fully formed target structures can be verified using native gel electrophoresis, which gives size and shape information for the nucleic acid complexes.  An electrophoretic mobility shift assay can assess whether a structure incorporates all desired strands.  Fluorescent labeling and Förster resonance energy transfer (FRET) are sometimes used to characterize the structure of the complexes.Nucleic acid structures can be directly imaged by atomic force microscopy, which is well suited to extended two-dimensional structures, but less useful for discrete three-dimensional structures because of the microscope tip's interaction with the fragile nucleic acid structure; transmission electron microscopy and cryo-electron microscopy are often used in this case.  Extended three-dimensional lattices are analyzed by X-ray crystallography.

Question: What does the mobility shift assess?
Answer: whether a structure incorporates all desired strands
At the end of May 1921, Khiagt came under pressure from Baron Ungern's forces, who moved towards Soviet Russia. This offensive was repulsed by mid-June, with the help of troops of the Far Eastern Republic. At the end of June, the People's Partisans and the Red Army decided to attack Khüree. They reached the town on July 6, having destroyed smaller groups of Ungern's forces on the way.

Question: What army attacked Khuree?
Answer: Red Army
Immediately after the congress, the provisional government and the MPP central committee decided to seize the Mongolian part of Khiagt from the Chinese troops, and on February 15 an ultimatum was sent to the Chinese military authorities in the town. The Chinese commanders refused to surrender, and on March 18, Sükhbaatar's troops succeeded in taking the town, despite being heavily outnumbered. This day is now the official holiday of Mongolia's army, and is usually celebrated as the equivalent of Defender of the Fatherland Day in Russia. The provisional government moved to the Mongolian part of Khiagt and began to establish Ministries of the Army, Finances and Foreign Affairs, but when a fire in the aftermath of the battle burnt down the greater part of the town, the government moved on to Altanbulag.

Question: In what town was the fighting held that eventually led to March 18th being the official holiday of Mongolia's army?
Answer: the Mongolian part of Khiagt
In 1912, Russian advisers to the Bogd Khan set up a military school at Khujirbulan, and Sükhbaatar was one of the soldiers transferred there. His talent for military tactics and his skills at riding and shooting earned him the respect of his comrades, and after the training he became a platoon leader of the machine gun company at Khujirbulan. In 1913, he set up his own household with his wife Yanjmaa. They had had their first son in 1911, but Yanjmaa's parents objected to the relationship on the grounds that Sükhbaatar was too poor.

Question: When did the platoon leader have his first son?
Answer: 1911
Sükhbaatar's widow Yanjmaa went on to serve in a number of senior positions in the Mongolian government, including acting president.

Question: Who was Yanjmaa?
Answer: Sükhbaatar's widow
The new government was not in a secure position, and rumours of anti-communist plots increased. In 1922, Bodoo, Chagdarjav, Da Lama Puntsagdorj and others were executed on allegations that they had collaborated with internal and external enemies of the new state. In early 1923, amid official suspicions that a coup was planned for Tsagaan Sar, the state of alert became too exhausting for Sükhbaatar. He broke down on the night of February 14/15, and died on February 20. In the 1940s under Choibalsan's reign, it was alleged that Sükhbaatar had been poisoned, but later socialist publications did not explicitly discuss the cause of death. Nonetheless, this version is still somewhat popular in Mongolia. Some historians say that he died of pneumonia, because of cold rain. Neither version could be proved officially.

Question: Who did Sukhbaatar suspect there was a coup planned for in 1923?
Answer: Tsagaan Sar
Following the completion of the dialogue sessions, producer Chris Thomas was hired to provide "a fresh pair of ears".  Thomas's background was in music, rather than engineering.  He had worked with Beatles producer George Martin, and was acquainted with Pink Floyd's manager Steve O'Rourke. All four members of the band were engaged in a disagreement over the style of the mix, with Waters and Mason preferring a "dry" and "clean" mix which made more use of the non-musical elements, and Gilmour and Wright preferring a subtler and more "echoey" mix. Thomas later claimed there were no such disagreements, stating "There was no difference in opinion between them, I don't remember Roger once saying that he wanted less echo.  In fact, there were never any hints that they were later going to fall out.  It was a very creative atmosphere.  A lot of fun." Although the truth remains unclear, Thomas's intervention resulted in a welcome compromise between Waters and Gilmour, leaving both entirely satisfied with the end product.  Thomas was responsible for significant changes to the album, including the perfect timing of the echo used on "Us and Them".  He was also present for the recording of "The Great Gig in the Sky" (although Parsons was responsible for hiring Torry). Interviewed in 2006, when asked if he felt his goals had been accomplished in the studio, Waters said:

Question: What manager was Chris Thomas friends with?
Answer: Steve O'Rourke
Much of the album's early American success is attributed to the efforts of Pink Floyd's US record company, Capitol Records.  Newly appointed chairman Bhaskar Menon set about trying to reverse the relatively poor sales of the band's 1971 studio album Meddle.  Meanwhile, disenchanted with Capitol, the band and manager O'Rourke had been quietly negotiating a new contract with CBS president Clive Davis, on Columbia Records.  The Dark Side of the Moon was the last album that Pink Floyd were obliged to release before formally signing a new contract.  Menon's enthusiasm for the new album was such that he began a huge promotional advertising campaign, which included radio-friendly truncated versions of "Us and Them" and "Time". In some countries – notably the UK – Pink Floyd had not released a single since 1968's "Point Me at the Sky", and unusually "Money" was released as a single on 7 May, with "Any Colour You Like" on the B-side.  It reached number 13 on the Billboard Hot 100 in July 1973. A two-sided white label promotional version of the single, with mono and stereo mixes, was sent to radio stations.  The mono side had the word "bullshit" removed from the song – leaving "bull" in its place – however, the stereo side retained the uncensored version.  This was subsequently withdrawn; the replacement was sent to radio stations with a note advising disc jockeys to dispose of the first uncensored copy. On 4 February 1974, a double A-side single was released with "Time" on one side, and "Us and Them" on the opposite side. Menon's efforts to secure a contract renewal with Pink Floyd were in vain however; at the beginning of 1974, the band signed for Columbia with a reported advance fee of $1M (in Britain and Europe they continued to be represented by Harvest Records).

Question: Who was Pink Floyd's record company in the US?
Answer: Capitol Records
Returning from the US in January 1973, they recorded "Brain Damage", "Eclipse", "Any Colour You Like" and "On the Run", while fine-tuning the work they had already laid down in the previous sessions.  A foursome of female vocalists was assembled to sing on "Brain Damage", "Eclipse" and "Time", and saxophonist Dick Parry was booked to play on "Us and Them" and "Money".  With director Adrian Maben, the band also filmed studio footage for Pink Floyd: Live at Pompeii. Once the recording sessions were complete, the band began a tour of Europe.

Question: What year was their return to the US?
Answer: 1973

Question: What was the footage the band filmed used for?
Answer: Pink Floyd: Live at Pompeii
