The Microraptor Gui: Link Between Bird and Dinosaur Essay -- Explorato

The Microraptor Gui Link Between Bird and DinosaurThe DebateFor years paleontologists have debated intensely about the origin of birds. How did air-borne birds evolve? How did they learn to soak up flight? Are they linked to dinosaurs? If they are, which species of these reptiles are the birds closest related to? The FindFrom 2001 and 2002, six new basal dromaeosaurid specimens from the Lower Cretaceaous Jehol Group in Chaoyang Basin in western Liaoning, China, were prime. These six specimens of the Microraptor gui, previously known genus Microraptor, were discovered by Xing Xu from the Institute of Vertebrate Paleontology and Paleoanthropology. Microraptor gui gets its name in honor of Gu Zhiwei, a renowned paleontologist who contributed greatly to the study of Jehol biota. So far over 60 species of fossil plants, 1000 species of fossil invertebrates, and 70 species of fossil vertebrates have been found in these rocks, dating back to the Late Jurassic or Early Cretaceous periods. Recently there has been much media attention to these rocks that yield such brisk information in the evolution of birds, and origins of feathers. The Microraptor gui is 77 cm in length. It is believed to have lived between 124 and 145 million years ago. The Microraptor Gui has four travel in total. Interestingly, it has a wing on each hind-limb. The Microraptor gui is a birdSome will argue that the Microraptor gui was a bird. Feathers cover its completed body. It has forelimbs much like the wings of modern birds, and modified for flight. The pelvis characteristics derived from basal birds. The Microraptor gui had a vane on one side of the feathers spine that was wider than the other. This nuance of design strongly suggests these fe... ... and theropauds has also been illustrated in popular modern movies such as Jurassic Park III. Here Steven Spielberg accurately depicts the impertinently found details of the raptors. Contrary to the first two editions of the movie, this time th e raptors have feathers at the top of their heads. In order to allow the audience to easily fuck these fierce carnivores from the prequels of the movie the change was not drastic, but it was a positive step in accurately depicting dinosaurs in movies. To solve the whole point of linking birds and dinosaurs one would need to find a feathered dromaeosaur adapted to life in the trees as opposed to on the ground, and the Microraptor gui seems to be just this. done the discovery of Microraptor gui it is clear that birds share a common ancestry with small carnivorous dinosaurs called dromaesaurs found in the theropod group.

Catch-22 :: essays research papers fc

Catch-WhatCatch-22 is one of the most poorly constructed, and distasteful books Ive ever read. Its order of events, or lack of order, becomes clear after the very low chapter. In fact It doesnt even seem to have been written instead it gives the impression of having been shouted onto paper (Stern 50). By the middle of the book it seems each character in the book has lost any sense of morality they may have seemed to have. The novel gasps for want of craft and sensibility (Stern 50).It seems to me that the only mode to keep track of the order of events throughout the book is to pay attention to how many missions Colonel Cathcart has assigned. Immediately, even after the first chapter, chronological order is not followed. harmonize to The Structure of Joseph Hellers Catch-22 by Jan Solomon the order of events seemed to follow two different time lines. The first, of course, was that of Yossarian. Yossarians time line follows his psychological perception of events (Potts 20). The ea rly(a) time line that appears in the book, according to Solomon, is that of Milo Minderbinder. Even this interpretation of the book having an order of events has a couple flaws in it. The biggest is that Milo and Yossarian are mentioned in concert in the book sooner they are introduced later in the book. The most apparent event that came to mind, was that they appeared together at Snowdens funeral in the tree before they were introduced later in the book, which is actually earlier in time. The book shows how personal morals are destroyed when faced with the thought of not being in that location the next day. Many early reviewers complained that the novel had no moral center (Potts 67). The women in the book take the hardest hit. The charges Heller gives to the women, if he gives them a name at all, clearly states how they are portrayed, such as Natelys Whore, Nurse Duckett, and Dori Duz. Although Scheisskopfs wife and Luciana dont have suggestive names, they are portrayed desire the other women as well. An example of how offensive the women were in the book would be when Scheisskopfs wife and Dori Duz slept with all the men stationed in the United States under lieutenant Scheisskopf. The men in the book, however, are just as bad as the women. Colonel Cathcart shows how he is driven with greed and selfish-ambition.

catcher in the rye Essay -- essays research papers fc

Hello, is Salinger There?J. D. Salingers only published full-length novel, The catcher in the Rye, has become one of the most enduring classics of American literature. The novels story is told in retrospect by the main character, Holden Caulfield, while staying in a psychiatric hospital in California. This is a orgasm of age tale that is wrought with irony. Holden Caulfield, Mr. Antolini, and Phoebe are the main symbols of irony. The first and most obvious subject of irony is the novels protagonist, Holden Caulfield. His hatred for anything dissembler is ironic because he to is deceitful. He is constantly performing by taking a new identity for each new situation he is in. For example, in the train scene he makes up stories ab discover one of his classmates in order to delight his classmates mother. He not only initiates a new identity for himself, but he also spawns a whole new fictional account of life at Pencey Prep. He even admits that he is an impressive liar. Because of his hatred for anything artificial, he searches for something real. In his nave and desperate way he is searching for anything which is innocent and sincere (Parker 300). He fantasizes about removing himself from society and adequate a reclusive deaf mute. Regardless of his independent personality, he clearly demonstrates how severely he needs companionship. His thoughts are always of his sister, Jane Gallagher, and additional people. Another fondness of Holdens is to be the catcher of childrens innocence. Holdens fantasy elaborates his obsession with innocence and his perhaps surprisingly moral code (Walters 1009). However, it is clear that his real need is to be salvaged from the emptiness of his negativism. This is realized when he tele remembers Mr. Antolini and when he admits that he almost hopes that his parents will catch him as he sneaks out of the apartment. The Catcher, in fact, wants to be caught, the deliveryman saved (Engle 45). Mr. Antolini is the subject of irony bec ause he is actually a catcher, even though he is a different kind of catcher from the one Holden imagines. Holden believes that he has already fallen over the cliff into the dissatisfaction that automatically goes together with adulthood. He felt the world has let him slip trough the cracks alone and unassisted. Therefor... ... Holden states What really knocks me out is a book that, when youre all done reading it, you wish the author who wrote it was a terrific friend of yours and you could call him up on the phone whenever you felt like it (Salinger 18). J.D. Salinger is not available for phone conversations, but generations of readers have felt that the book alone provides that kind of close connection with its author (Guinn). work citedEngle, Steven, ed.

On March 11, 2002 we learned the difference in the midst of gasoline engines and diesel engines. Gasoline engines drop low power, low efficiency, are quiet, have an easy cold start, cause less pollution, controlled emissions, and easily converted. Diesel engines give high power, high efficiency, are noisy, difficult cold start, more pollution, and it is more difficult to control emissions. There are severe environmental impacts from fossil fuel use. These impacts are found in all stages, recovery, transportation, refining,storage,and end use. During recovery of coal, the earth suffers destruction of topsoil as well as acidic run cancelled creating orange creeks and land subsidence. Petroleum production causes on land and off shore drilling as well as gushers and accidents. During transportation accidents can exceed and are pretty much routine. This causes massive pollution of the seas. Preparation or refining creates refuse and sludge from coal cleaning plants. With petroleum air and water pollution are caused. In storage, gasoline leaks in underground tanks at gas stations are a threat. During end use, pollutants from combustion occur. Also, the release of atomic number 16 and nitrogen oxides pose a threat. On March 18,2002 we learned of measures to reduce the environmental pollution from fossil fuel use.
