conclusion, hip arthroscopy has the following advantages over a traditional hip arthrotomy. 1) It does not require dislocation of the hip, which lessens serious complications such as avascular necrosis of the femoral head. (2) Under the arthroscopic magnification, good visualisation of pathology can be done properly with arthroscopic instruments. 3) Hip arthroscopy because of and a short rehabilitation period allows early return to functional status after the…

Karissa Walter 12/13/15 Anatomy & Physiology I Professor Jenkins Sensory Impairment in Older Adults: Part 2: Vision Loss As adults age there is a persistent declination in age related eye degeneration. Many times this occurs naturally with age, but can also be a result of medical conditions found in older patients. A portion of these medical conditions include macular degeneration, cataracts, glaucoma, and diabetic retinopathy. These visual impairments can lead to a need for…

PURPOSE The purpose of this lab was to isolate DNA from a strawberry. METHODS We used a variety of materials to extract the DNA from the strawberry. These include a disposable cup, a rubber band, a plastic knife, a zipper bag, a pipet, a coffee filter, ethanol, a lysis buffer, a test tube, an inoculating loop, and a strawberry. The general objects that we used for convenience and safety include a lab coat, a tray to cut the strawberry, and lots of paper towels. The…

type of cell dye, were added to each well of the plate. After another minute, the dye was removed and the plate was rinsed under a trickle of water until no more visible dye was left over. The plate was then examined under a microscope at 4 times magnification, and in each well, the number of cells that stuck to the bottom of the plate were counted for a total of 10 trials per…

A politician is a person who is currently in hold of a position or is seeking an office within a government. They gain power by election being either voted for by people or by a definitive group in the government. And a politician’s purpose is to support and create laws or policies that would govern the land and its people. In Thomas L. Friedman’s op-ed article, he stated that "politicians see evil, hear evil, and speak evil" in order to present to the citizens that politicians have taken their…

In the field of Microbiology, it is essential that the microorganisms being examined are seen clearly and distinctly under the microscope. Most specimen thrive in aqueous environments, therefore they are translucent and when mounted on a microscope the light passes through them making it impossible to see the specimen. Equally as important as this is that the viewer is aware of what type pf bacteria is being utilized. Both of these criteria in a lab are met with the use of a staining procedure…

younger and had only just come out of university he helped Niccolò Tantaglia mathematically describe ballistics and the force of friction. Then after discovering more about moving objects he invented his first telescope in 1609 with 20 times the magnification allowing him to have a closer look at the moon. Then a year later published his findings called “The Starry Messenger ” talking about how he discovered four of jupiters moons, lots of new stars, the phases of venus and sun spots then…

chloroplasts were very difficult to see and cyclosis was unable to be observed. Cyclosis, or the movement of chloroplasts, is generally uniform in rate and direction of movement. In comparison, plant cells are much larger than bacteria. At the same magnification, the elodea cells are much larger and easier to see than the lactobacillus cells. This increase in size is allowed because of the endomembrane system in eukaryotes like plants. The cell wall, composed of cellulose fibers, was the most…

The Nose The Nose features a twisted ending which is hard to conclude on what exactly happened. The narrator here tries to convince us that social rank plays an important part in determining a person’s life. The events of the story indicate that appearance was important for a man with a high rank. The value of fellow government official’s opinions is very high as Kovalyov says, “If the major doesn’t split his sides when he sees me, then everything is in the right place. (Gogol, 21).” At this…

An electron vacancy is created and is further filled by an electron from the higher shell and thus an X-ray is emitted to balance the difference in energy between the two electrons. The detector placed on the energy dispersive spectroscope apparatus measures the number of emitted X-rays and their energies. Energy of the X-ray is characteristics of the element from which X-ray is emitted. A spectrum of the relative counts of the detected X-rays is obtained and evaluated for quantitative…
