Q: A friend asked me to answer this question: What has difficulty preventing rotation in firn and at boundaries between layers of different densities?, using the article: The two main requirements of an anti-torque system are that it should prevent rotation of the sonde, and it should allow easy movement of the drill up and down the borehole. Attempts have been made to design drills with counter-rotating components so that overall torque is minimized, but these have had limited success. Five kinds of anti-torque systems have been devised for use with cable-suspended EM drills, though not all are in current use, and some drills have used a combination of more than one design. The first drill to require an anti-torque system was used at Camp Century by CRREL in 1966; the drill incorporated a set of hinged friction blades that swung out from the sonde when the drill motor was started. These were found to have very weak friction against the borehole wall, and were ineffective; the drill had to be controlled carefully to prevent twisting the cable. No other drills have attempted to use this approach.For the next deployment of the drill leaf springs were installed, and this has proved to be a more durable design. These are mounted vertically, with a curve outwards so that they are easily compressed by the borehole wall, and can slide up and down with the movement of the drill. They pass easily through any areas of irregularity in the borehole, but the edges of the springs cut into the borehole wall and prevent rotation. Leaf springs are very simple mechanically, with the additional benefit of being easy to adjust by changing the spacing between the end points. They can be placed anywhere on the drill that does not rotate, so they do not add length to the sonde. The shape is usually a fourth-order parabola, since this has been determined to provide the most even loading against the borehole wall. Leaf springs have been found to be so effective that they can prevent rotation even in heavy drills running at full power.Skate antitorque systems have blades attached to vertical bars which are pushed against the borehole wall; the blades dig into the wall and provide the..., what would be the answer ?

Question: A friend asked me to answer this question: What is the first name of the person that is Dr. Ballan's patient?, using the article: A package is delivered to Gail, a young blonde woman with a roommate named Peggy. Gail opens the package to find a pair of binoculars, but when she uses them to look out a window, she screams and collapses, dying. The binoculars are revealed to have two spikes emerging out of the eyepiece. Peggy is being interviewed by Superintendent Graham and Inspector Lodge when journalist and crime writer Edmond Bancroft enters the room. He wishes to see the binoculars for himself, and Graham remarks on their similarity to binoculars in Scotland Yard's "Black Museum". Bancroft then purchases a dagger at Aggie's antique shop. Returning to his house, he enters his secret basement museum with his assistant Rick. The museum exhibits various weapons and implements of torture used by criminals. Bancroft visits his doctor, Dr. Ballan, and tells him that he cannot rest until the killer is apprehended. Ballan observes that Bancroft goes into a state of shock after the murders, noting that he needs psychiatric treatment and should be hospitalized. Bancroft later visits his mistress Joan in her flat, who argues with him, asking for money and calling him a cripple. Joan leaves her apartment for a bar where she dances provocatively to music from a jukebox. She returns to her flat and prepares to sleep, but when she lays down on her bed she gasps, seeing a guillotine and a man with a hideous face above her bed frame. When the guillotine blade falls she screams, gathering curious neighbors at her door. The hideous man pushes his way through this crowd when he makes his escape. Graham investigates, questioning the crowd of neighbors who mention the man's strange appearance., what would be the answer ?
Answer: Edmond
[Q]: A friend asked me to answer this question: What is the name of the person that released a book that chronicled her struggle with weight and confidence?, using the article: Jackson announced plans to embark on her largest world tour in support of her second hits collection, Number Ones. The tour, entitled Number Ones, Up Close and Personal, held concerts in thirty-five global cities, selected by fans who submitted suggestions on her official website. During the tour, Jackson performed thirty-five number one hits and dedicated a song to each city. Mattel released a limited-edition Barbie of Jackson titled "Divinely Janet", auctioned for over $15,000, with proceeds donated to Project Angel Food.Jackson released the self-help book True You: A Journey to Finding and Loving Yourself in February 2011, co-written with David Ritz. It chronicled her struggle with weight and confidence, also publishing letters from fans. It topped The New York Times' Best Seller list the following month. Additionally, she signed a film production contract with Lions Gate Entertainment to "select, develop and produce a feature film for the independent studio."Jackson became the first female pop singer to perform at the I. M. Pei glass pyramid at the Louvre Museum, raising contributions for the restoration of iconic artwork. Jackson was selected to endorse fashion line Blackglama for a second year, being the first celebrity in the line's history chosen to do so. She partnered with the label to release a fifteen-piece collection of luxury products.In 2012, Jackson endorsed Nutrisystem, sponsoring their weight-loss program after struggling with weight fluctuations in the past. With the program, she donated ten million dollars in meals to the hungry. She was honored by amfAR for her contributions to AIDS research when chairing the Cinema Against AIDS gala during the Cannes Film Festival. She also participated in a public service announcement for UNICEF to help starving children., what would be the answer ?

[A]: Jackson
Question: A friend asked me to answer this question: Who is shown lying on her back with breasts exposed?, using the article: A number of plates in this group reveal a scepticism towards idolatry of religious images. There are instances in the group where early Christian iconography, in particular statues and processional images, are mocked and denigrated. Plate 67, Esta no lo es menos (This is no less curious), shows two statues carried by two stooped members of clergy. One statue is recognisable as the "Virgin of Solitude". In Goya's image, the statue is not carried vertically in processional triumph, rather it lies flat and undignified on the backs of the two almost crouched men. Shown horizontal, the object loses its aura, and becomes a mere everyday object. Art critics Victor Stoichita and Anna Maria Coderch wrote, "It is in effect a deposed, toppled image, stripped of its powers and its connotations." Goya is making a general statement: that the Church's attempts to support and restore the Bourbons were "illusory, since what they proposed was nothing more than the adoration of an empty form".The published edition of The Disasters of War ends as it begins; with the portrayal of a single, agonized figure. The last two plates show a woman wearing a wreath, intended as a personification of Spain, Truth, or the Constitution of 1812which Ferdinand had rejected in 1814. In plate 79, Murio la Verdad (The Truth has died), she lies dead. In plate 80, Si resucitara? (Will she live again?), she is shown lying on her back with breasts exposed, bathed in a halo of light before a mob of "monks and monsters". In plate 82, Esto es lo verdadero (This is the true way), she is again bare-breasted and apparently represents peace and plenty. Here, she lies in front of a peasant., what would be the answer ?
Answer:
a woman wearing a wreath
