...true FISP and 3d FLASH sequences was 15 ml/lt. Ten patients underwent conventional enteroclysis with 1.5 lt of 20% barium sulfate enema and 22.5 ml of gadolinium. MR Enteroclysis was performed afterwards using true FISP, fat suppressed 3d FLASH and fat suppressed HASTE sequences. In all patients the proposed contrast medium acted as positive in 3d FLASH (T1w), true FISP (T2/T1 w) and as a negative in HASTE (T2w). In conclusion, a 20% barium sulfate enema with 15 ml/lt gadolinium is appropriate for conventional and MR Enteroclysis studies. Keywords: MRI, contrast medium, gadolinium, Crohn's disease, Enteroclysis Text Introduction Fast and ultrafast sequences, high performance gradient coils and dedicated abdominal phased array coils resulted in significant improvement in MR Imaging of the small bowel (SB). Resent reports indicated that MRI may be clinically useful for anatomic demonstration, identification and characterization of SB abnormalities, providing information from the bowel lumen - wall and the mesenteries (1-8). However, there is no consensus on the optimum sequences that should be used for SB imaging or on the appropriate contrast media for lumen opacification. In the present study different gadolinium concentrations within a 20%...

...They also had a long history of running at least 5 to 20 years. Before the competition started there were three runners that presented normal lateral menisci. There was eight grade I lesions; four grade II and three grade III lesions. “One participant who underwent resection of the posterior horn of the lateral meniscus 15 years previously and presented with a graded IIIB lesion of the posterior horn of the lateral meniscus in the other knee. After running there was no signal alteration that graded differently from the initial findings”. The MRI scans of those participants that were healthy before the race with no previous muscle injuries, after the marathon the MRI scans proved that no negative long-term-effects were experienced. In contrast, those that previously had high-grade lesions of the menisci, after the marathon might be at risk of greater injury of the knee, like osteoarthritis. W. Krampla, R. Mayrhofer, J.

...Phase Contrast Microscopy Phase Contrast Microscopy, first described in 1934 by Dutch physicist Frits Zernike, is a contrast-enhancing optical technique that can be utilized to produce high-contrast images of transparent specimens, such as living cells (usually in culture), microorganisms, thin tissue slices, lithographic patterns, fibers, latex dispersions, glass fragments, and subcellular particles (including nuclei and other organelles). In effect, the phase contrast technique employs an optical mechanism to translate minute variations in phase into corresponding changes in amplitude, which can be visualized as differences in image contrast. One of the major advantages of phase contrast microscopy is that living cells can be examined in their natural state without previously being killed, fixed, and stained. As a result, the dynamics of ongoing biological processes can be observed and recorded in high contrast with sharp clarity of minute specimen detail. The phase-plate increases the phase difference to half a wavelength. Destructive interference between the two sorts of light when the image is projected results in the specimen appearing as a dark object. The phase contrast microscope uses the fact that the light passing through a transparent part of the specimen travels slower and, due to this is shifted compared to the uninfluenced light. This difference in phase is not visible to the human eye. However, the change in phase can be increased to half a wavelength by a transparent...

...OMPARE AND CONTRAST Compare and Contrast Two Short Stories Both Kate Chopin in "The Story of an Hour" and James Thurber in "The Secret Life of Walter Mitty" discuss the relationship between married couples. As will be set forth in this paper, the authors reach similar conclusions through very different methods. Neither character relates well to his/her spouse and both are in an unhappy marital situation. It is fairly certain that both Mitty and Mrs. Mallard are loved by their spouses and according to all outward appearances, are in good marriages. Both long to be free, but both have trouble admitting that fact to themselves in a way that will allow them to do something about their situations. Both short stories examine the ironic reality that far from making some people happy, love can be a prison. Alienation, isolation, and the basic need for freedom of spirit are themes running through both stories. The authors make their points with very different uses of form, style, and content. The short story narrative is used by both authors. Both have a clear time frame, well developed characters, well defined settings, and are told from the third person omniscient perspective (Clugston, 2010). Chopin writes a brief scene from Mrs. Mallard's life which stuns the reader with the knowledge that Mrs. Mallard is joyful at the news of her husband's death. The story covers the space of only one hour, but that hour is filled with revelations about Mrs. Mallard (as cited in Clugston...

...-Outfielders must cover large distances, so speed, instincts, and quickness in reacting to the ball are key. They must be able to catch fly balls above their head and on the run. They must be able to throw the ball accurately over a long distance to be effective; they must also learn to judge whether to attempt a difficult catch and risk letting the ball get past them, or to instead allow the ball to fall in order to guarantee a swift play and prevent the advance of runners. in baseball, a left fielder is an outfielder who plays defense in left field. Left field is the area of the outfield to the left of a person standing at home plate and facing towards the pitcher's mound. In the numbering system used to record defensive plays, the left fielder is assigned the number 7. Left fielders must also familiarize themselves with the varying configurations of different ballparks' foul territory, and prevent balls hit down the foul lines from getting past them into the left field corner. Amateur players may find it difficult to concentrate on the game, since they are so far from the action. Emphasizing the correct position will give outfield players something to concentrate on at each pitch. Hits to left field tend to curve toward the left field foul line, and left fielders must learn to adjust to that. Of all outfielders, the left fielder often will have the weakest arm, as they generally do not need to throw the ball as far to prevent the advance of any base-runners. The left fielder...

...Body Paragraphs: Point-by-Point Each of your three body paragraphs will follow this format. Each paragraph will focus on a specific point of contrast (PC). Remember that a point of contrast is a quality that both subjects possess in different ways. This is called a “difference in kind.” Apples and oranges both have seeds, but they have different kinds of seeds. Your points of contrast should avoid the Not/-Er Fallacy. In other words, you must write about the actual characteristics of each subject and not simply say one has X but the other does not, or that one has X but the other has more X. Topic Sentences (T) You will have two topic sentences in each paragraph. One will come at the beginning of the paragraph and identify the first subject as it relates the point of contrast (the general difference). After you have provided the necessary information (see below), use a transitional expression (on the other hand, in contrast, however) and write the second topic sentence which will identify the second subject as it relates to the point of contrast. Support Distinguishing Characteristics (DC) After each topic sentence, you will present in specific, clear detail the characteristics that distinguish the first subject from the second. The details you present will vary. If you were writing about the characteristics that distinguish an apple seed from an orange seed, you would need to use description in order to show the reader what makes the apples seed different. If...

...Epistemological Comparison and Contrast Dorothy M. Conner University of Phoenix Epistemological Comparison and Contrast Descartes ' Theory of Knowledge Rene Descartes is one of the most renowned rationalists of the modern age who asserts that knowledge can be obtained by means of reason. He claims that in the acquisition of knowledge one should be able to distinguish what is true and what is false. This leads to his opposition against the idea of experience as a source of knowledge As Descartes claims it, one should not rely on experience as a source of knowledge for the reason that experience is deceptive as how a person's sensory organs can bring deception with the way he or she perceives things (i.e. the bending of the pencil when submerged in water). Descartes furthers states that because of this fallibility of experience one cannot really arrive at true knowledge by merely being dependent on what he or she perceives through experience. As a result of Descartes treatment of experience, he suggests that to attain genuine and true knowledge, one should defer his or her judgment on things that are represented to him or her by experience unless such are presently proven to be unquestionable. Descartes is a perplexity in many ways. Although he has a refreshing distaste for the voodoo logic of his day steeped as it was in the questionable science of the scholastic movement, when provoked he was equally capable of skewing his own thinking when confronted with the entrenched...

...Contrast Essay When family from another state comes to visit you want to show them some of the activities that their home town does not provide. There are so many options people can choose from. I think two of the most common places people go to when they have visitors are theme parks or city fairs. Theme parks and city fairs are very different and each provides us with their type of fun activities. Theme parks have a great advantage over city fairs when it comes down to rides, bigger location, and price. Many people prefer theme parks because they offer better activities for fun, which gives theme parks an advantage over city fairs. An advantage theme parks have would be the rides. Everyone who has been to a theme park enjoys its rides. The rides are fast and they go in different directions which makes it better for the customers because it does not make them dizzy. They also last for a longer a period of time which makes it worth wild because sometimes you have to wait in line for an hour or even more. Also, theme parks are located in bigger place which gives more people the opportunity to attend at whatever time they like and still find tickets available. The bigger location of the park comes in handy because it does not get crowded and you have enough space to walk comfortable without anyone bumping into you. Another advantage theme parks have over city fairs is the price. The tickets are around thirty dollars and sometimes they have offers were you buy one get...

...Contrast To Develop Characters in the Lottery Ticket and the Persian Carpet The author uses many different techniques such as contrast to develop characters in the story The Lottery Ticket by Anton Chekhov and The Persian Carpet by Hanan Shaykh which involves intellectual processes. A representation to express and shape up contents in stories explaining the effects of the characters has on the readers. Firstly, in the story The Lottery Ticket; a family which consists of Ivan and Masha Dmitrich living their lives as middle aged couple. Author describes the characters as unfortunate, showing their desire into winning lottery. Also, the couples have no luck or faith in winning a lottery only to be announcing as a winner when they finally look at the numbers. Euphoric Ivan and Mesha are "torment and tantalize...with hopes of possible fortune is so sweet, so chilling!" It makes a strong bond in their relationship yet unjust trust since the two have other intentions in using the money for something else. Winning lottery is something they could not believe, dreams that are impossible is possible until they realizes the winning ticket does not have the right numbers. Ivan and Mesha have been assuming that they are the winners of the lottery all along, leaving their materialistic possessions from there. However, in the story The Persian Carpet is another scenario.

...Compare and contrast essays are effective in all areas for my life. Comparing two items that are similar can be positive, however contrasting these items may not be the best way to write about them. Comparing two items that are very different would not be the best way to write about them. Comparing thru contrast would be a much better essay. The idea of writing any essay is to interest the reader to the point where they do not want to stop reading the paper. It is important to capture the reader’s attention, and to keep their interest until the end of the story, or essay. Comparing two ideas that are similar and comparing their similarities could be detailed on how you could change something about the subjects to be able to show their differences. Letting the reader make their own conclusions after giving them the information will help to get the reader involved. subjects. The situations in which these are most effective are professional reflections. Professional comparisons are usually backed by professional primary sources. Those are primary sources can give factual information about both viewpoints in the essay. Personal reflections in a compare and contrast essay is slightly more ineffective as usually personal emotions can get in the way of being objective. If you take one side of a two viewpoint subject, you would find the essay favor the side you have taken. Professional compare and contrast essays are coming from multiple viewpoints. These viewpoints are factual...

...Compare and Contrast Paper Ray Sweeney CMJ 306 October 4, 2012 Don Crist Abstract In the following paper, this author will compare and contrast the communication lessons learned in the assigned reading and movie. This author will discuss the successes and failures that can be created by effective communication or the lack thereof. Compare and Contrast Paper Effective communication is key to successful leadership. According to Schroeder and Lombardo (2006), there are ten principles for effective communication. They are; know your objectives, choose your language, consider your environment, rehearse, know your spoken and unspoken message, role play, feedback, hypocrisy, don’t over communicate and listen (p. 99). All of the were used by President Lincoln (Phillips 1993). A leader must be able to use all of the above steps in order to communicate an effective message and get the end results he or she wants. President Lincoln was a very effective communicator and felt that his communication style was key to his successes. Lincoln could talk to anyone using humor and witty stories, which he used as persuasive tools (p. 399). In comparison to Mandela in the movie Invictus (2009), Lincoln used his persuasive, yet honest communication style to win the election in 1860. Mandela was elected as President in 1990 after being incarcerated for 26 years and pledged an oath to unite the people of South Africa. Lincoln’s style was a bit different during...

...Compare-Contrast Essay The thought of doing an essay for most people can at be quite intimidating because of the need to be technically proficient, following the mandatory expectations outlined and some might find them boring because they feel like it is too restrictive in nature. That is merely just a common misconception though, there are several different styles of essays and the two that are going to be discussed are descriptive and narrative essays. The narrative essay's main purpose is to tell a story using characters and a plot, where perhaps a problem is given, and the events that unfold eventually explain a solution to the problem or issue presented. In contrast the descriptive essay can be very powerful in the fact it is written using the five senses (visual, audible, taste, tactile sensations and smells) this allows the author to bring a scene or object to life in the mind of the reader. While narrative essays are almost like a movie that is played out in the judgment of the reader, the descriptive essay paints a vivid photograph or place the reader can experience and this is why descriptive essays are the superior of the two styles. One of the best qualities that narrative essays are able to offer over descriptive essays is they are structured to appeal to the simplest of mankind's urge to share a good story. There are various forms in which we can find a narrative writing example such as a poem, play, novel and the obvious essay. There are times...
