Bone dissection Essay

The skeletal system is made up of cartilage and bone. Both bone and cartilage are connective tissues, that is, they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells, the gelatin the support material for matrix, and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances, we can produce a material that is very hard like bone and can withstand weight or softer like cartilage which can be used as a cushioning material. In this exercise, we will examine a fresh raw chicken bone to study bone structure. Materials Note: To complete both experiments, you will need two raw chicken bones. Each experiment requires a separate bone. Fresh chicken leg bone Knife Procedure 1. Carefully remove the skin and muscles from the bone as you do this, note the way that muscles are attached.. 2. Split the bone lengthwise. 3. Examine the bone and locate the following structures: a. Tendon – Examine the attachment of the muscles to bone. In most cases, the long ropelike attachment is a tendon and is composed of dense regular connective tissue. b. Periosteum This thin membrane covers the outside of the bone. c. Articular cartilage Note this thin layer of cartilage covering the epiphysis. d. Marrow cavity This hollow cavity in the diaphysis of the bone is lines with a thin membrane called the endosteum. e. Spongy bone This type of bone is located in the ends or epiphyses of the bone and appears to be open with small spicules or bars. f. Compact bone Makes up the shaft or diaphysis of the bone. Questions 1. How does spongy bone differ from compact bone? What differences did you see in the appearance of the spongy bone and compact bone? What color was the spongy bone? 2. How does cartilage differ from bone? How did each one feel when pierced with the knife? 3. How did the periosteum and endosteum differ in thickness? 4. Was the bone marrow yellow, red, green or blue? 5. What type of cartilage makes up the articular cartilage? 6. How did the articular cartilage differ in appearance from the spongy bone? 7. What color was the tendon? What substance gives it strength? 8. How did the raw bone differ in appearance from the baked bone in the other experiment? Note: Chicken may be contaminated with Salmonella. Wear gloves when possible during handling and wash hands thoroughly at the conclusion of your work!! Note: There are questions that will tell me if you did the dissection as I asked. If you miss these questions, you will receive no credit for the dissection.

Humor in Lysistrata and She Stoops to Conquer Still Funny Today

Humor in Lysistrata and She Stoops to Conquer Still Funny Today Aristophanes classical Greek play Lysistrata and Oliver Goldsmiths 18th century British play She Stoops to Conquer, both contain various types of humor. The humor found in these plays was certainly enjoyed by the audiences of the time. However, it is certainly true that much of this humor is still enjoyed today.Advertising We will write a custom essay sample on Humor in Lysistrata and She Stoops to Conquer: Still Funny Today specifically for you for only $16.05 $11/page Learn More For contemporary audiences yet delight in the satire of Lysistrata, the farcical comedy of manners in which the themes of national war and peace, and yes, even war and peace between the sexes, all receive humorous treatment. Next, She Stoops to Conquer is a comedy of manners, where irony prevails amid frequent misunderstandings. Set in the environs of that prevailing polite society, the characters try very hard to preserve the amenities and civility, but frequently fail, as their t rue actions become known. First, in Lysistrata, there is much levity in the degree to which the men are made to appear foolish, and to be rather easily manipulated by their women. Further, constant sexual innuendos abound. There is humorous interplay between the choruses of old men and women. Clearly, the language is very earthy and bawdy. For example, in Part 12, an exchange between several chorus members goes thusly: The woman threatens, â€Å"Suppose I let fly a good kick at you?† Whereupon, the old man rejoins with, â€Å"I should see your thing then.† Then, the woman, older herself as well, has the last word with stating, â€Å"You would see that, for all my age, it is very well plucked.† (Aristophanes 753) Further, a primary component of the costuming was an enormous phallus, constructed from leather. And all the men persistently maintain large penile erections. In addition, theres sexual referencing throughout the play. Then, there are incongruous and rid iculous situations as well. A definite slapstick element is present as women run after old men using their spindles as weapons.Advertising Looking for essay on comparative literature? Let's see if we can help you! Get your first paper with 15% OFF Learn More Then, too, even the dialogue between Lysistrata and the commissioner debating the futility of war is mildly funny. (Aristophanes 782) In addition, note how Aristophanes blends the slapstick scene of the women chasing of old men with weapons like weaving spindles and the intellectual humor of the commissioners attempt to argue with Lysistratas exposition of the incompetence of the mens pursuit of the war. The culmination comes when the warriors return from the Peloponesian Wars, all with gigantic erections. Their women tease them further by showing them a nude female servant, which only makes the men feel more desperate. However, the women will not allow their men sexual satisfaction, until all Athenians a nd Spartans declare a truce. In the second play, She Stoops to Conquer, the elitist Charles Marlow is a study in contradiction. A snob by nature, he does actually seek out servants and maids rather than females from the upper classes. The main premise of the play is that he is en route to meeting up with a family friend, and is â€Å"pranked† on the way, which actually ends up with a variety of misunderstandings. There is humor in these events, such as culture clashes and identity confusion. Also hilarious are the secretive love entanglements surrounding himself and the other male protagonist. He even has a slightly humorous way of insulting a young lady, claiming, â€Å" Goodness ! What a quantity of superfluous silk hast thou got about thee, girl! (Goldsmith 41) Then, on his journey, he becomes lost, and levity ensues when he and his companion are told, Why, gentlemen, if you know neither the road you are going, nor where you are, nor the road you came, the first thing I h ave to inform you is, that - you have lost your way. (Goldsmith 55) This is definitely understated humor.Advertising We will write a custom essay sample on Humor in Lysistrata and She Stoops to Conquer: Still Funny Today specifically for you for only $16.05 $11/page Learn More Finally, another example that will provoke a chuckle is the scene between Tony and Hastings. Hastings asks eagerly, where has Tony left the ladies. Tony them replies, by way of a riddle, â€Å"Left them? Why, where should I leave them, but where I found them? (Goldsmith 176) In summary, these are but a few of the scenes and references from these two plays that may be as funny today, as they were at the time of the original productions. It is definitely true that although humor evolves through time, some elements of levity remain both timeless and universal.

Free Essays on James Chadwick

SIR JAMES CHADWICK (1891 –1974) James Chadwick was born in Cheshire, England, on October 20, 1891. James is the son of John Joseph Chadwick and Anne Mary Knowles. He attended Manchester High School prior to entering Manchester University in 1908. Strangely, while enrolling in the University of Manchester, Chadwick who intended to major in mathematics accidentally found himself in the physics line. Too shy to admit his mistake, he stayed in line. Good thing he made that mistake because he eventually receives the Nobel Prize in Physics in 1935. He graduated from the Honors School of Physics in 1911 and spent the next two years under Professor (later Lord) Rutherford in the Physical Laboratory in Manchester, where he worked on various radioactivity problems, gaining his M.Sc. degree in 1913. That same year he was awarded the 1851 Exhibition Scholarship and proceeded to Berlin to work in the Physikalisch Technische Reichsanstalt at Charlottenburg under Professor Hans Geiger. During World War I, he was interned in the Zivilgefangenenlager, Ruhleben. After the war, in 1919, he returned to England to accept the Wollaston Studentship at Gonville and Caius College, Cambridge, and to resume work under Rutherford, who in the meantime had moved to the Cavendish Laboratory, Cambridge. Rutherford had succeeded that year in disintegrating atoms by bombarding nitrogen with alpha particles, with the emission of a proton. This was the first artificial nuclear transformation. In Cambridge, Chadwick joined Rutherford in accomplishing the transmutation of other light elements by bombardment with alpha particles, and in making studies of the properties and structure of atomic nuclei. He was elected Fellow of Gonville and Caius College (1921-1935) and became Assistant Director of Research in the Cavendish Laboratory (1923). In 1927 he was elected a Fellow of the Royal Society. In 1932, Chadwick made a fundamental discovery in the domain of nuc...

Analysis of the theory of recruitment practices in SMEs

Analysis of the theory of recruitment practices in SMEs The focus of this essay is to use observations from an ethnography study conducted in a small Chinese restaurant in the city of Bradford in carrying out an analysis of the theory of recruitment practices in small and medium – sized enterprises (SME’s). It will begin with a brief description of the study and the organization involved with details of all that was observed during the period of the period of the study. The results will thereafter be linked with theories relating to recruitment practices in SME’s drawing from a wide range of academic literature and a conclusion will be drawn based on what has been found and the overall implication with regard to knowledge in the field. It was a cold Thursday afternoon at the end of a seemingly endless array of lectures and tutorials. I decided to visit a Chinese restaurant in the Bradford city center for a taste of oriental cuisine and particularly make some observation on how small businesses operate in this environ ment. On arrival at the restaurant, a relatively cozy setting existed which created a sense of warmth and relaxation; exactly what I needed. I was greeted warmly by a female waitress who appeared to be Chinese although I’m aware she could be from anywhere in that region. There were quite a number of customers in the restaurant at that moment mostly busy with one meal or the other. Being a buffet, there was a lot of moving around with people getting up to take their meals from the service sections. I took a sit in a nice corner, place the order for my drinks and decided to look around for a while before my meal. The aesthetics of the restaurant was quite impressive with the walls painted in a combination of orange and brown, the lighting just right for the atmosphere, tables of various sizes depending on the number of guests and the right amount of decorations on the walls. How can I forget the soft music playing in the background? Even though I couldn’t understand a wo rd of what was being sung as it was in Chinese, the melody was just right. The nationalities of the guests appeared to be all encompassing. There were six middle-aged Caucasian males, two elderly females with a toddler, tow male Asians, a black female couple and three other young black female guests already seated in the restaurant. Three female Chinese waitresses were on hand to attend to guest needs and there was a male waiter at the bar who was in charge of the drinks. The kitchen staff that came out every now and again to replenish the stock of food was also of Chinese origin. This set me wondering on what criteria was required for employment in this restaurant. During the period of my observation, more guests came into the restaurant which comprised of two young female Caucasians, two adult female Pakistanis, one male Pakistani and a group of twelve made up of eleven males and one female all appearing to be from the same workplace as they were all dressed as having come for a f ormal lunch or to celebrate a successful business deal.

Mc Donalds Essay Example | Topics and Well Written Essays - 500 words

Mc Donalds - Essay Example ing out of the 1990s, the company had gained an ugly reputation for having ‘single-handedly’ led the nation to its current dangerous levels of obesity (Branch, 1997). Reviled for its unhealthy food products and questioned about its quality, the numerous appeals the company made to try to appease the public were solidly rejected. However, McDonalds seems to be making a strong come-back based upon its new campaign focused on intelligent and healthy choices as revealed on their website. McDonald’s current marketing campaign makes constant appeals to the intellect and to healthy living. Rather than using the obvious color ploys of yesteryear’s designs, the McDonalds website (http://www.mcdonalds.com) offers rich tones of color that introduce sophistication and complication to the simpler red and yellows of the chain’s early years. However, bright colors are still used on the kids’ pages reserved for very young children, still learning how to use the mouse and keyboard. This is in keeping with psychological and developmental studies that suggest very young children are more attracted to simple, bright color schemes (Ratner, 1989). The site is also very sophisticated in its use of technology, providing combinations of fully integrated streaming media, flash game pages and easy and accessible xhtml pages. These impressions are backed up with the content of the site in which consumers are made to feel as if everything they want to know is ava ilable on the site, education is stressed through the emphasis placed on Hamburger University and children’s activities are geared to teach as well as provide entertainment while still supposedly revealing to children (who likely can’t read yet) that this site is an advertisement. In addition to these appeals to the consumer’s presumed intellect, and perhaps more importantly to its own success, the company is also making tremendous appeals to the public’s need for healthier food choices. Their biggest push

Comparing the 1962 Version of The Manchurian Candidate with the 2004 Essay

Comparing the 1962 Version of The Manchurian Candidate with the 2004 version - Essay Example The movie-making industry is inseparable from the political and historical conditions, in which it operates. Even fantastic movies and horrors cannot escape the dramatic influence of historical and political realities. The Manchurian Candidate was first created in 1962. Featuring Frank Sinatra, the movie was a compound product of multiple historical, social, and technical influences. The fear of Communism, the rapid spread of McCarthyism, and the Cold War altogether contributed to the development of a sophisticated vision of war, which, taking place thousands of miles from the American continent, profoundly alters the American political landscape. On the social background, an evolutionary nature of a social role a woman plays in the society is evident. At first, in the version of 1962 year, the main character was a manipulative woman, but there was no essential political influence of this heroine. In the version of 2004 year, this character becomes a Senator. Therefore, it is clearly seen that social factor has contributed greatly to the social accents set in the new version of the film. Moreover, there is a lack of sensual transfer of intimate relations between the main characters. Thus, for example, Lansbury’s character kissing Shaw inspires the audience and creates a romantic atmosphere. In the modern version there is no such kind of a romantic aura between the characters. Political Differences-The concept of â€Å"fear† is integrative for both films. Two great powerful machines that are consuming contemporaries are presented with the same powerful manner: in the first version of the film there is an atmosphere of fear in the face of communism and in the second film the characters are afraid of being absorbed by a powerful corporate machine. Therefore, it is evident that historical events and periods of films’ creation influenced the main conceptual framework of both film versions. The influential and powerful factor of fear in the face of communism (in 1962 version) was substituted by another fear factor in the version of 2004. Another political factor that is rather controversial in the modern version is the way assassination is represented. A great emphasis is made on a â€Å"programmed nature† of assassinator’s mind. At this point we can see an intricate interconnection between political and technological factors. This i nterpretation of assassination is justified in the modern version as it is strongly backed up by the modern technological developments. Moreover, another explanation is provided. The matter of natural/unnatural changes of human behavior is explained in terms of technological advancements or as a result of mental disorders. This director’s intention can be interpreted in the following way: whether modern technologies are able to re-program human mind or not, the latter would be either way perverted by his own psycho. The Manchurian Candidate (1962) is probably one of the brightest and memorable products of the American moviemaking industry. Featuring Frank Sinatra, The Manchurian Candidate is a movie, where â€Å"the stepson of a presidential candidate turns out to have been a prisoner of war who underwent interrogation at the hands of Chinese communists† (Delgado 23). The soldier is brainwashed and programmed to assassin a Presidential Candidate.
