studied objects to discover what affected their ability to move on surfaces. He never published his theories therefore has never received credit for his findings. Guillaume Amontons (1663-1705) He studied friction to discover that friction was the affect two surfaces had on each other. Charles August Coulomb (1736-1806) He continued Amontons studies to add to the second law of friction. F. Philip Bowden and David Tabor They investigated friction to discover that friction is related to the true area
Introduction Dupuytren’s Disease, also known as Dupuytren’s Contractures, palmar fascitis, Viking Disease, or palmar fibromatosis, is a hand deformity that usually develops slowly, usually over years. This disease is caused by the thickening and contraction of the palmar fascia. As the disease progresses, nodules progress to form longitudinal bands referred to as cords on the palmar fascia, and the finger gradually loses extension, with contractures that draw one or more fingers into flexion at
Dupuytren’s. There is no known screening procedure such as DNA, laboratory tests or other diagnostic tests. It is hoped one day with the assistance, of DNA scientists will come up with a screening test for the living patient and the unborn child. Baron Guillaume Dupuytren (October 5th, 1777 – February 8th 1835) was a French anatomist and military surgeon.He is best known today for Dupuytren's contracture, which is named after him and which he described in 1831, However, he was not the first to describe it
disease,” Dupuytren’s condition is found in people of European descent wherever they originated on the continent (Eaton). Millions of people suffer from the disease today. However, the condition was reported by Guillaume Dupuytren in 1831. “Getting to Grips with Celtic Hand”). Baron Guillaume Dupuytren, French anatomist and military surgeon is best known today for his treatment Dupuytren’s disease. He performed the first corrective surgery in 1831 (“Sticky Finger”).

melody of a motet that is the color or the melodic pattern. Philippe de Vitry and Guillaume Machaut are the two most representative composers of this music style. Both composers wrote sacred and secular music in a variety of styles. For the purpose of analysis, the pieces Cum statua/Hugo, Hugo/Magister invidie composed by Philippe de Vitry in 1320 and Felix virgo / Inviolata / Ad Te Suspiramus composed by Guillaume de Machaut in 1360 will serve as a subject of comparison and contrast to determine
the family’s honor. It was also different in that it did not begin with a prologue, like most of the other tales. Chaucer’s main influence of the tale was the Roman de la Rose (Romance of the Rose) which was written by Guillaume de Lorris and finished by Jean de Meung. Both Guillaume and Meung referred to the historical story written by the Roman author Titus Livius, or Livy, for their source. It was said that the tale was probably unrevised because it contained many confusions and contradictions.
How do people go missing? Well, there are many explanations to this question. Kidnappings, disappearing by choice, death at sea, running away, and so many more things can answer how people go missing. However, maybe there is a more important question. Why do people go missing? A child goes missing in the United States every 40 seconds. With adults and children together just in the United States that equals about 2,300 every day and over 800,000 every year. The worldwide estimate is that over 8,000
According to the text books Anthology for Music in Western Civilization and Music in Western Civilization, this piece was composed by Philippe de Vitry in 14th century France. It is an ars nova motet so the text was usually political, satirical, or hermetic and was usually written and understood by the educated elite who attended universities. This work was an example of Philippe’s involvement in royal politics; he expressed his criticism toward the corrupt court. This piece was a contribution to
Most of the early music that we have today still in print is primarily sacred music. This music, for the most part, is in the form of sections of the Mass, such as the Gloria, Kyrie and Agnus Dei. Most people of the Middle Ages were poor peasants who worked all day for meager wages and had no idle time lounging the way the upper classes did. Therefore, there are few extant secular compositions of music from this era. The rise of a new middle class, however, gave financial freedom for some people
Guillaume de Machaut was born in 1300 in France and passed on April 13, 1377 in Rheims,France. He was mainly known to be in the 14th century which is the middle ages. “Generally acclaimed the greatest composer of the fourteenth century.” His work is very famous as well as he is. One of his most famous works would be the “Messe de Notre Dame.” His life has been very enlightening and so many historic events that he has been through which shaped his life and his music made him even better. He was also
of a gas. Contrary to its name, this relationship was actually discovered by French scientific instrument inventor and physicist Guillaume Amontons, and is occasionally referred to Amontons’ Law of Pressure-Temperature. While Guy-Lussac did explore the temperature-pressure relationship, Guy-Lussac’s law is usually used to refer to the law of combining volumes. Amontons stubble across this relationship when he was building an “air thermometer.” Although not many have been able identify his exact method
The Effect of Weight on Sliding Friction Between a Block and Surface Planning ======== In this investigation we are going to find out what effect weight has on sliding friction. Friction is the force that is between two objects that are in contact with each other. The force is always present even though people only think it is there when the object is moving. Leonardo da Vinci was one of the first people to experiment with the idea of friction. He came up with two types of friction;
Gas Laws Since the days of Aristotle, all substances have been classified into one of three physical states. A substance having a fixed volume and shape is a solid. A substance, which has a fixed volume but not a fixed shape, is a liquid; liquids assume the shape of their container but do not necessarily fill it. A substance having neither a fixed shape nor a fixed volume is a gas; gases assume both the shape and the volume of their container. The structures of gases, and their behavior, are
