Q: What is the answer for the question: What is the name of the drilling fluid for which protective clothing, and in some cases masks, may be necessary for people exposed to it due to its flammability and corrosiveness? from the following article ?  Drilling fluids are necessary for borehole stability in deep cores, and can also be used to circulate cuttings away from the bit.  Fluids used include water, ethanol/water and water/ethylene glycol mixtures, petroleum fuels, non-aromatic hydrocarbons, and n-butyl acetate. Water is the cheapest and cleanest option; it may be present on the glacial surface or may be created by thermal drilling.  In cold ice some form of antifreeze is necessary, or heat must be reapplied by reaming the hole periodically. Ethanol and water.  Ethanol acts as an anti-freeze in water; at sufficient concentrations it can reduce the freezing temperature of the mixture to well below any temperature likely to be encountered in ice drilling.  The concentration must be chosen to prevent the liquid freezing and also to maintain the borehole against the ice overburden pressure.  Because the density of the mixture decreases with lower temperatures, vertical convection will develop in boreholes where temperatures decrease with depth, as the lighter mixture rises.  This causes slush to form in the borehole, though successful drilling is still possible.  Ethanol is one of the cheapest options for a drilling fluid, and requires less storage space than other options because in use it is diluted with water.  A Soviet expedition left an 800 m borehole in Antarctica filled with ethanol and water at an ice temperature of −53 °C; after 11 months the borehole remained open and drilling was resumed with no problems.  A problem with this option is that the mixture will penetrate cores that have cracks. Ethylene glycol and water was used at Camp Century in 1966 in the lower part of the hole to dissolve the cuttings. Petroleum fuels.  This includes diesel, jet fuel, and kerosene. They are inexpensive and easily available, and were once in common use; disadvantages include flammability and the aromatics they contain, which are a health hazard. Non-aromatic hydrocarbons.  As of 2009 these had become the most commonly used drilling fluids; eliminating the...
A: n-Butyl acetate

Q: What is the answer for the question: What was the first name of the person made the Grand Tour in his youth? from the following article ?  Holkham was built by 1st Earl of Leicester, Thomas Coke, who was born in 1697. A cultivated and wealthy man, Coke made the Grand Tour in his youth and was away from England for six years between 1712 and 1718. It is likely he met both Burlington—the aristocratic architect at the forefront of the Palladian revival movement in England—and William Kent in Italy in 1715, and that in the home of Palladianism the idea of the mansion at Holkham was conceived. Coke returned to England, not only with a newly acquired library, but also an art and sculpture collection with which to furnish his planned new mansion. However, after his return, he lived a feckless life, preoccupying himself with drinking, gambling and hunting, and being a leading supporter of cockfighting.  He made a disastrous investment in the South Sea Company and when the South Sea Bubble burst in 1720, the resultant losses delayed the building of Coke's planned new country estate for over ten years. Coke, who had been made Earl of Leicester in 1744, died in 1759—five years before the completion of Holkham—having never fully recovered his financial losses. Thomas's wife, Lady Margaret Tufton, Countess of Leicester (1700–1775), would oversee the finishing and furnishing of the house.Although Colen Campbell was employed by Thomas Coke in the early 1720s, the oldest existing working and construction plans for Holkham were drawn by Matthew Brettingham, under the supervision of Thomas Coke, in 1726. These followed the guidelines and ideals for the house as defined by Kent and Burlington. The Palladian revival style chosen was at this time making its return in England. The style made a brief appearance in England before the Civil War, when it was introduced by Inigo Jones. However, following the Restoration it was replaced in popular favour by the Baroque style. The "Palladian revival", popular in the 18th century, was loosely based on the appearance of the works of the 16th-century Italian architect Andrea Palladio. However it did not adhere to Palladio's...

Q: What is the answer for the question: What is the name of the band that recorded at Windmill Lane Studios? from the following article ?  After the October Tour, U2 decamped to a rented cottage in Howth, where they lived, wrote new songs, and rehearsed for their third album, War. Significant musical breakthroughs were achieved by the Edge in August 1982 during a two-week period of independent songwriting, while the other band members vacationed and Bono honeymooned with his wife Ali. From September to November, the group recorded War at Windmill Lane Studios. Lillywhite, who had a policy of not working with an artist more than twice, was convinced by the group to return as their producer for a third time. The recording sessions featured contributions from violinist Steve Wickham and the female singers of Kid Creole and the Coconuts. For the first time, Mullen agreed to play drums to a click track to keep time. After completing the album, U2 undertook a short tour of Western Europe in December. War's lead single, "New Year's Day", was released on 1 January 1983. It reached number 10 in the UK and became the group's first hit outside of Europe; in the US, it received extensive radio coverage and peaked at number 53. Resolving their doubts of the October period, U2 released War in February. Critically, the album received favourable reviews, although a few UK reviewers were critical of it. Nonetheless, it was the band's first commercial success, debuting at number one in the UK, while reaching number 12 in the US. War's sincerity and "rugged" guitar were intentionally at odds with the trendier synthpop of the time. A record on which the band "turned pacifism itself into a crusade", War was lyrically more political than their first two records, focusing on the physical and emotional effects of warfare. The album included the protest song "Sunday Bloody Sunday", in which Bono lyrically tried to contrast the events of the 1972 Bloody Sunday shooting with Easter Sunday. Other songs from the record addressed topics such as nuclear proliferation ("Seconds") and the Polish Solidarity movement ("New Year's Day"). War was U2's first record to feature...
