Please answer this: Given the following context: The ice must be cut through, broken up, or melted. Tools can be directly pushed into snow and firn (snow that is compressed, but not yet turned to ice, which typically happens at a depth of 60 metres (200 ft) to 120 metres (390 ft)); this method is not effective in ice, but it is perfectly adequate for obtaining samples from the uppermost layers. For ice, two options are percussion drilling and rotary drilling. Percussion drilling uses a sharp tool such as a chisel, which strikes the ice to fracture and fragment it. More common are rotary cutting tools, which have a rotating blade or set of blades at the bottom of the borehole to cut away the ice. For small tools the rotation can be provided by hand, using a T-handle or a carpenter's brace. Some tools can also be set up to make use of ordinary household power drills, or they may include a motor to drive the rotation. If the torque is supplied from the surface, then the entire drill string must be rigid so that it can be rotated; but it is also possible to place a motor just above the bottom of the drill string, and have it supply power directly to the drill bit.If the ice is to be melted instead of cut, then heat must be generated. An electrical heater built into the drill string can heat the ice directly, or it can heat the material it is embedded in, which in turn heats the ice. Heat can also be sent down the drill string; hot water or steam pumped down from the surface can be used to heat a metal drillhead, or the water or steam can be allowed to emerge from the drillhead and melt the ice directly. In at least one case a drilling project experimented with heating the drillhead on the surface, and then lowering it into the hole.Many ice drilling locations are very difficult to access, and drills must be designed so that they can be transported to the drill site. The equipment should be as light and portable as possible. It is helpful if the equipment can be broken down so that the individual components can be carried separately, thus reducing... answer the following question: What can heat the material it is embedded in?
++++++++
Answer: An electrical heater

Problem: Given the following context: The first copies were delivered to bookstores on September 10. Many were wary of it, due to its technical nature, and feared that sales would be low. An exception was Scribner's Bookstores, which placed large early orders. At Oak Ridge, the Manhattan Project's major production site, 8,000 copies were sold through the employee welfare organization. Similar arrangements were made for Los Alamos and Richland, which were located in areas where bookstores were scarce.The Smyth Report was on The New York Times bestseller list from October 14, 1945, until January 20, 1946. Between 1946 and when the Smyth Report went out of print in 1973, it went through eight printings, and Princeton University Press sold 62,612 paperback and 64,129 hardback copies.Groves did not intend the Smyth Report to be the last word on the project. It formed an addendum to the Manhattan District History, the official history of the project. This eventually consisted of 35 volumes with 39 appendices or supplements. It was written in the immediate postwar years by the chemists, metallurgists, physicists, and administrators who had worked on the project. Since there were no security restrictions, it covered every aspect of the Manhattan Project, but was itself classified. Most of it was declassified in the 1960s and 1970s and became available to scholars, except for some technical details on the construction of the bombs.In her 2008 PhD dissertation, Rebecca Schwartz argued that Smyth's academic background and the Smyth Report's security-driven focus on physics at the expense of chemistry, metallurgy, and ordnance promoted a public perception of the Manhattan Project as primarily the achievement of physics and physicists. According to Schwartz, postwar histories and popular writing tended to follow the Smyth report in this regard, creating a lasting historiographical legacy. "Ever since", wrote Jon Agar, "the atomic bomb has been seen as an achievement of physics." In particular, the prominence given to Einstein's massenergy equivalence... answer the following question: What was the date that The Smyth Report was first released?

A: September 10

Q: Given the following context: Jackson's fifth studio album Janet, was released in May 1993. The record opened at number one on the Billboard 200, making Jackson the first female artist in the Nielsen SoundScan era to do so. Certified sixfold platinum by the RIAA, it sold over 14 million copies worldwide.Janet spawned five singles and four promotional singles, receiving various certifications worldwide. The lead single "That's the Way Love Goes" won the Grammy Award for Best R&B Song and topped the Billboard Hot 100 for eight consecutive weeks. "Again" reached number one for two weeks, while "If" and "Any Time, Any Place" peaked in the top four. "Because of Love" and "You Want This" charted within the top ten.The album experimented with a diverse number of genres, including contemporary R&B, deep house, swing jazz, hip hop, rock, and pop, with Billboard describing each as being "delivered with consummate skill and passion." Jackson took a larger role in songwriting and production than she did on her previous albums, explaining she found it necessary "to write all the lyrics and half of the melodies" while also speaking candidly about incorporating her sexuality into the album's content. Rolling Stone wrote "[a]s princess of America's black royal family, everything Janet Jackson does is important. Whether proclaiming herself in charge of her life, as she did on Control (1986), or commander in chief of a rhythm army dancing to fight society's problems (Rhythm Nation 1814, from 1989), she's influential. And when she announces her sexual maturity, as she does on her new album, Janet., it's a cultural moment."In July 1993, Jackson made her film debut in Poetic Justice. While the film received mixed reviews, her performance was described as "beguiling" and "believably eccentric." Jackson's ballad "Again", which was written for the film, received Golden Globe and Academy Award nominations for "Best Original Song."In September 1993, Jackson appeared topless on the cover of Rolling Stone, with her breasts covered by her then-husband, Rene Elizondo,... answer the following question: What is the full name of the person who Rolling Stone states is influential, whether proclaiming herself in charge of her life, as she did on Control, or as commander in chief of a rhythm army dancing to fight society's problems?
A:
Janet Jackson
