Please answer this: A friend asked me to answer this question: What is the name of the specific category of drilling fluid that includes includes diesel, jet fuel, and kerosene?, using the 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..., what would be the answer ?

Please answer this: A friend asked me to answer this question: What is the last name of the cousin of the father of the woman that David falls in love with?, using the article: Young David Balfour arrives at a bleak Scottish house, the House of Shaws, to claim his inheritance after his father. The house and land have been under the custodianship of his father's brother, Ebeneezer Balfour, but on reaching adulthood, the land and property become David's. Ebeneezer is having none of it, however, so he first tries to murder him, then has him kidnapped by sea captain Hoseason, with whom he has "a venture for trade in the West Indies". David is shipped off to be sold as a slave in the Carolinas. He strikes up a friendship with Alan Breck, escaping from Prince Charles Edward Stuart's defeat at Culloden. Breck is in a cobble which is run down in the fog by Hoseason's ship and once aboard, asks Hoseason to take him to France. When Hoseason refuses, Breck offers him 60 guineas to put him down on Loch Linnhe. On discovering that Breck has a money belt full of Jacobite gold, Hoseason and his crew try to kill Breck, but he is forewarned by David and the two kill half a dozen of the crew before the others retreat. Hoseason offers terms to end the fighting, but the ship runs aground. Only Breck and Balfour appear to survive and they manage to get to land. They set out for Edinburgh, dodging the ruthless Redcoats. Numerous adventures follow as they meet up with Breck's family, friends and foes alike. These include Breck's cousin, James Stewart, and his daughter Catriona, with whom David falls in love., what would be the answer ?

Answer: Breck

Please answer this: A friend asked me to answer this question: What marked an increase in scale for music videos?, using the article: Before the success of Thriller, many felt Jackson had struggled to get MTV airing because he was black. In an effort to attain air time for Jackson, CBS Records President Walter Yetnikoff pressured MTV and declared, "I'm not going to give you any more videos and I'm going to go public and fucking tell them about the fact you don't want to play music by a black guy."His position persuaded MTV to begin airing "Billie Jean" and later "Beat It", (along with Prince's "Little Red Corvette") which led to a long partnership and later helped other black music artists to gain mainstream recognition. MTV denies claims of racism in their broadcasting. The popularity of his videos, such as "Beat It" and "Billie Jean", helped to place the young channel "on the map" and MTV's focus shifted in favor of pop and R&B. Jackson transformed the medium of music video into an art form and promotional tool through the use of complex story lines, dance routines, special effects and cameo appearances by well known personalities.When the 14-minute-long Thriller video aired, MTV ran it twice an hour to meet demand. The short film marked an increase in scale for music videos and has been routinely named the best music video ever. The popularity of the video sent the album back to number one in the album chart, but Jackson's label did not support the release of the third music video from the album. They were already pleased with its success, so Jackson convinced MTV to fund the project.Author, music critic and journalist Nelson George wrote in 2004, "It's difficult to hear the songs from Thriller and disengage them from the videos. For most of us the images define the songs. In fact it could be argued that Michael is the first artist of the MTV age to have an entire album so intimately connected in the public imagination with its imagery". Short films like Thriller largely remained unique to Jackson, while the group dance sequence in "Beat It" has been frequently imitated. The choreography in Thriller has become a part of global pop..., what would be the answer ?
