Microscopes and Microscopy Essays

Microscopes and Microscopy Essays Microscopes and Microscopy Paper Microscopes and Microscopy Paper A microscope, whether simple (one lens) or compound (multiple lenses), is an instrument that magnifies an image and allows visualization of greater detail than is possible with the unaided eye.   The simplest microscope is a magnifying glass or a pair of reading glasses. Microscopes are used for research wherein it commonly has a number of refinements to enable a complete study of the specimen. Because the image of a specimen is highly magnified and inverted, manipulating the specimen by hand is very difficult. As a result, the stages of high-powered research microscopes are mounted so that they can be moved by means of micrometer screws; in some microscopes, the stage can also be rotated. In addition, all research microscopes are equipped with three or more objectives, mounted on a revolving head, so that the magnifying power of the microscope can be varied. Discussion: The letter ‘e’ was inverted ‘  Ã‚   ‘.   The virtual image formed passed through a series of biconvex lens.   As the light pass through the lens, the image is inverted so as it appears and seen by the observer. The threads were ordered as red, green to yellow from top to bottom.   All magnifications gave a bit of idea regarding the orientation of the thread but 100x mag gave the best visual representation of the image being magnified.   Four hundred (400X) times magnification on the other hand revealed the specific detail details of the image being magnified.   The depth of field has affected the resolution of the image while objects situated at the top tend to appear blurred as compared to the image at the bottom. The interpupilary distance is adjusted towards or away from the eyepiece diopter.   Bring the sample very close to focus using the microscope focus slider while observing the image formed in the left eyepiece.   Utilize the left eyepiece diopter slider to bring the sample into sharp focus when the specimen approaches focus.   Using the right eyepiece diopter slider focus the specimen matching the left eyepiece. It is best to use the scanning or low power objective to have an overall view of the specimen and help the observer decide to which part of the specimen he will focus and bring to a higher magnification.   Shifting to a higher objective after locating the area of interest is done by turning the revolving nosepiece to the plane at which a higher objective is aligned at along the path of light.   The resolution and location of the specified are not very much changed due to the parfocal and parcentral features of the modern microscope. In bright field microscopy as you increase the magnification, you will also need to increase the amount of light necessary to see the object.   Therefore reducing the iris diaphragm aperture at high magnification may bring about distortion on to the image being magnified.   It is always that the smallest amount of light possible is used to view the object clearly. She could try to adjust the iris diaphragm aperture to increase the amount of light passing through the specimen.   She could also try adjusting the sub stage to increase the distance between the specimen and the source of light.   Increasing the distance between lenses increases the magnification therefore requiring higher light intensity to produce better magnification and resolution.

The Disparity Rate between Women Committing and Incarcerated for Essay

The Disparity Rate between Women Committing and Incarcerated for Crimes in America vs Men Committing Crimes - Essay Example In order to do this, I will discuss the influence of traditional gender stereotypes and the false impression of equality to provide support for the argument that women are indeed mistreated in the workplace; and the stories and characteristics of women who become successful in the corporate world, and the true origin of the glass ceiling, if gender-based or policy-initiated, to substantiate the claim that the glass ceiling has been broken and that women are actually treated well and respected in the corporate world. II. The Glass Ceiling: Women are mistreated in the Workplace Traditional gender stereotypes have historically positioned women in a child-rearing, nurturing, passive and subservient role whereas men are perceived as the governing, more forceful gender. Self-assured and aggressive behaviors of the males are regarded as more important due to its attributes of objectivity, lack of prejudice, and focus toward analytical work or problem solving. Traditional views of males indi cate they are more appropriate to managerial and executive positions than females due to their leadership orientation. Men seem to be more commanding or domineering whereas women go for a more involved and compassionate approach. Further traditional or stereotypical perspectives on the variation men and women are seen from a psychoanalytical point of view in a current commentary in the American Psychologist by the well-known Harry Levinson. As Levinson states, the male focus and orientation is characterized as incursion and drive against the female orientation of participation and environment. The entire psychology of management is all about self-assured approach and power; either to be on the top or on the bottom, defenseless, reliant and exploited (Coyne et al., 2004). Gender discrimination frequently prohibits women from management and executive positions. Gender stereotypes advocate males are mentally or intellectually better than women, are more psychologically stable, and are more focused on achievement and more aggressive than women. Effective and successful managers and executives are believed to have masculine features and attributes. Stereotypical belief and philosophy in organizations not merely affects the staffing and hiring of women to certain positions, it as well influences career growth and development and performance assessment. Societal standards and thoughts with respect to women often restrain women from being selected for managerial and executive positions in the business world. Terborg (1977) claimed the presence of a male managerial paradigm which states that women must not or cannot be effective managers or executives, which then preserves societal standards. Moreover, Terborg (1977) observed women often are disheartened or strained by occupational therapists and family members not to pursue nonconventional jobs, such as managerial positions. Goodale & Hall (1976) discovered students of high school of both genders who had comparable go als for college and career preference were not supported evenly by their families. Male students revealed their parents showed substantially more pressure and attention to their career aspirations than did the female students’ parents. Women who were rejected admission into medical colleges obtained

Gallery Paper - Essay Example A reflection of the Impressionist style is seen in Poppy Field whereby Monet depicts his perception through rough stokes of brush, vivid hues on a light colored canvas. The painting captures a spontaneous approach and depicts a snapshot of a scene that the artist has chosen. The most enthralling part of this painting is that it looks simplistic as opposed to complex; as if it were drawn with much ease. The painting depicts a typical day in Argenteuil’s summers (Murray). The most prominent part of the painting is the arrangement of various elements under consideration in the painting. The flat, horizontal flower bed is in strike contrast to the vertical stance of the trees. Furthermore, the striking green leaves stand in sheer contrast to the grass in the field which has been painted brown with a slight tinge of green as if it were dried. The essence of the painting is captured by the poppies that are painted vividly red with roughly six to seven random strokes of red brush at the bottom of the painting. To add to it, the sky stands in deep contrast to the rest of the painting with light blue hues and several scattered feathery clouds portraying a bright summer’s day. Monet has been more than just successful in outlining the sky with the aid of trees and the earth. The soil, although it encapsulates the largest space in the painting, gives an enthralling effect whereby its dark colors cause it to retreat and the white hues in the clouds cause it to become more prominent. Since the sky is in stark contrast to the trees and the soil, the ground and the trees drift the viewer’s attention to the sky. The perception of the artist is such that he controls the viewer’s eye movements by positioning the objects in a particular fashion. Hence, the viewer’s eyes first roll to the sky then towards the trees on the left side, and in the end towards the ground itself. It is a common mistake to think that because the ground depicts a lot of p eople that would be the most capturing position in the entire painting. In reality this is certainly not the case. Rather, the people become the most insignificant part of the painting, and that is simply because the people stand small in front of the greatness of the sky. At another instance also the painting demonstrates the insignificance of people by portraying three different people on the ground; the boy in the front who waves to the audience, and two women in the backdrop. Finally, the insignificance of man is further highlighted by the fact that the artist depicts a holistic view of man; he does not go into details and does not show the features of the boy of the women, in an attempt to merge them with the rest of the scenario. The boy is merely a figure and the artist does not even give the slightest hint of where his features ought to be. Furthermore, the hues used by Monet are bright ones, such as yellows, blues and greens; however, they tend to be not so bright or appear somewhat faded out by the scorching rays of the sun. We can, therefore, confidently say that the painting captures at length the sentiments of experiencing a typical summer’s day. Perhaps a significant aspect of this painting was that the outlines were thinned; the painting articulately depicted a melodrama of colors, a colorful fusion of brightly colored hues all blended together in an eloquent

Good Country People Stereotypes And Narcissism English Literature Essay

Good Country People Stereotypes And Narcissism English Literature Essay People must be comfortable with every aspect of themselves, because certain people, who in this story are represented by Manley Pointers character, can easily exploit their weaknesses. Hes good country people and the salt of the earth as Mrs. Hopewell refers to Manley Pointer who really is a demon that they must face. A demon to remind them of their weaknesses. Beginning with Mrs. Hopewell, the title of the story comes from what she likes to call the poorer and less fortunate people that live off the land and work their whole lives just to hang on to some scrap of a life. This is how she views these people. She believes that they are good country people not a bad seed among them, that they are all eager to help out and bow in humility to the upper class. The gullible nature of Mrs. Hopewell betrays her true vision of a situation. She is one of those people who are all goody-goody to people who they view as less fortunate. Shes a person that commends or speaks for the people she knows nothing about. Altogether this is her true weakness that is taken advantage of by Manley Pointer. One of Mrs. Hopewells favorite sayings, Nothing is perfect, is seen in the very beginning of the story. Her saying was just that; a saying. The quote acts as foreshadowing for what her attitude towards life will be. We later find out that she is right, but that she does not live by her credo. Manley Pointer exploits this weakness as soon as she opened her door. Showing up as a pathetic bible salesman with an ailing heart (which is coincidentally exactly what Joy-Hulga had) laying the old guilt trip on Mrs. Hopewell on how no one wants to deal with a simple country boy like himself, he attacks her weakness right at the heart of it. Not more than two minutes after he knocked on the door, he ends up eating dinner with them and at the conclusion is even invited to return any time hed like. His persona blinds Mrs. Hopewell and prevents her from being somewhat suspicious of Manley. At the en d of the story, we see that Mrs. Hopewell is still clouded by her weakness and refers to Manly as simple as he passes through a field by Mrs. Hopewell and Mrs. Freeman. Unlike Mrs. Hopewell, Joy-Hulga faces and comes to a realization of her weakness. Joy-Hulga, who had grown cynical and cold as she grew up with only one leg and heart ailment, creates an image that she is smarter and better than the rest of the characters in the story. Her education and self-absorption seemed to instill this attitude in her to greater extent than if she hadnt studied and read so much. Her weakness is the feeling of power she believed she gained from her studies. She refers to herself as a person who sees through nothing. Little does she know that she is stating her greatest weakness by saying this. Her hidden desires cause her several problems later on. After years of education and self-absorption, Joy-Hulga felt that she had no weaknesses. Science wishes to know nothing of nothing and this is the cr edo followed by Joy-Hulga. Her line of thinking turned out to be a weakness in itself. Her weaknesses are so prominent and hurtful from her childhood that she doesnt want to be reminded of them. Manley Pointer puts Joy-Hulga into a position where she feels in control. She took all his shame away and turned it into something useful. She believes that she is manipulating Manley, but it is he who is doing the manipulating. She lets her guard down because she feels in such great control and becomes comfortable with Manley. She is being manipulated from the start, and no amount of education can stop the fact that she doesnt see it coming. As soon as she admits to loving Manley Pointer, he sees the opening to completely destroy the facade she worked so hard to create her whole life. Before Joy-Hulga even knows it, her glasses are off and Manley has removed her leg. Physically she is broken down, but the real damage is done mentally. She knows that all control of the situation is out of he r hands, and she once again feels the discomfort felt during her childhood days. Manley Pointer exploits joy-Hulgas weakness to the fullest extent, because she never sees it coming. Joy-Hulga believed she was superior because she learned to see through nothing, but she doesnt realize that Manley has known this much longer than she which is even more prominent coupled with his seemingly lack of conscience. Manley is the only character in the story that has no apparent weakness. Taking into consideration the religious theme within the story, he takes on a persona of a devil-like character. He seems to be an almost omniscient character, which would fall in line with a powerful type of being. Being the protagonist in the story he acts not on an individual level, but more of a level revolving around mankind. His use of religion as a tool to carry out his acts of degradation and deception support this persona. He even says to Joy-Hulga, I hope you dont think I believe in that crap. Other things that represent this devil-like character is the hollow bible in which he kept instruments of a sort of sin. A definite clue to this is also when he also states to Joy-Hulga that He uses a different name every place he goes. The fact that the devil is referred to by many different names in all different regions of the world and different time throughout history shows another similarity between Manley Pointer and the devil. Manipulation and degradation seem to be his only objectives in life. At the conclusion of the story when Manley is passing by Mrs. Freemen and Mrs. Hopewell, the onion shoots that they are picking are even referred to as evil smelling the moment he passes. Mrs. Freemen is more of a minor character in the story but she is referred to as having two emotions, forward and reverse. This is important because then a person is forced to go in reverse they must face something or learn something they dont want to know about themselves. This seems to be what happens during the course of the story for Joy-Hulga. Although all the characters in the story are stuck in reverse, the only character that is forced to realize her weakness, which destroys the facade that she created is Joy-Hulga. It seems that in this story as in life the most high and mighty suffers the greatest fall. Joy-Hulga was the one who perceived herself to be the high and mighty of the characters. This attitude is displayed with many of her comment to Mrs. Hopewell. Perhaps when Joy-Hulga remarks to Mrs. Hopewell, Woman, do you ever look inside? she shouldve taken her own advice.

Racism: African American Races Essay

A social problem is a condition that at least some people in a community view as being undesirable. A big social problem in the world told would have to be racism. Some say that racism doesn’t exist but it does. Racism is a very strong word to use I have to say, but there have been a lot of unfairness and discriminations throughout the years in America. Which is what makes me interested in this topic the unfairness people receive from other people because the color of their skin. Some people I know have experienced unfair acts because of the content of their skin. Many people know that racism has occurred in the past when African Americans were treated unfairly being segregated from the opposite race. But most of that changed when people began to fight for equal rights having boycotts, protests, and consistently having those individuals who were racist know that they deserved equal rights as well as they did. And until they receive justice they were going to have their voices heard to receive justice. Racism is just with black people it’s with everybody. Any race can try anything, but there are still going to be those people who just converse with each other about other races. It’s definitely not only the Caucasian race it’s basically every race. The African-American race makes fun of the Caucasian and Latino races. The Latino race makes fun of the Caucasian and African American races. Everybody talks about everybody although it is not right I don’t believe that it will ever stop. I feel there should be a end to it simply because everybody is equal whether we want to believe it or not. So a stop to racism is a must it needs to happen now.

Factors Influencing Leadership Styles Essay

Personality Traits A leadership style may become an extension of a leader’s personality. If an individual is outgoing and assertive, he may prefer to communicate directly with subordinates through face-to-face interaction or confrontation, either on a group or individual basis. If he is more reserved, he might choose to lead by example or rely on written communication. Rather than addressing a group as a whole, the reserved leader is probably more comfortable meeting with subordinates on a one-on-one basis to provide individual direction. Level of Control The level to which a leader wishes to maintain control also influences leadership style. Some leaders want to be involved in all aspects of day-to-day operations and decision-making processes, which requires the need for micromanaging. Others may be more trusting of their subordinates or may not want the heavy burden of making all decisions, so they tend to take a more hands-off approach by delegating responsibility. Leaders who choose to delegate may need to create an additional layer of management. Organizational Structure An organisation’s structure and operating methods may dictate the type of leadership style that managers must adopt. Some organisations place heavy emphasis on encouraging contributions or ideas from their members, requiring an open style of leadership where members have a large say in determining their own roles and functions. Other organisations operate with more of a â€Å"my way or the highway† mentality, where leaders dictate direction and deviation or innovation is frowned upon. Experience A leader’s level of experience, both as a leader and with a particular organisation can have an impact on his style. Someone who is new to a leadership role may be more inclined to lead â€Å"by the book† to avoid potential mistakes, while a more experienced leader will often feel more confident in following his own interpretation of rules and regulations. A leader who has been part of an organisation for many years will likely have a better understanding of the organisation’s nuances than a new member, so she may be more comfortable when making decisions.

Essay on Thoreaus Civil Disobedience and Walden - 1529 Words

Henry David Thoreau (1817-1862) was an American philosopher, author, poet, abolitionist, and naturalist. He was famous for his essay, â€Å"Civil Disobedience†, and his book, Walden. He believed in individual conscience and nonviolent acts of political resistance to protest unfair laws. Moreover, he valued the importance of observing nature, being individual, and living in a simple life by his own values. His writings later influenced the thoughts of Mahatma Gandhi and Martin Luther King, Jr. In â€Å"Civil Disobedience† and Walden, he advocated individual nonviolent resistance to the unjust state and reflected his simple living in the nature. In â€Å"Civil Disobedience,† Thoreau stated that government should be expedient and conscientious. He started†¦show more content†¦Thoreau believed that the government should not be ruled by the minority just because â€Å"they are physically the strongest,† instead, we should be ruled by conscience. Furthermore, Thoreau stated that â€Å"†¦a corporation has no conscience,† because the corporation only cared about money, without caring about the multitude. This is still happening even nowadays. For instance, the cigarette companies are still selling cigarettes to the multitude even though they know that there are some carcinogenic materials in cigarettes that smoking cigarettes can cause cancers. They only care about money, without caring about the people who buy their products. As a result, most of the corporations had no conscience. Besides, people should also be conscientious. We should use our brains to think before we act. For example, the sol diers of the army had no conscience because they act like machines without thinking what they were doing. â€Å"The mass of men serve the state thus, not as men mainly, but as machines.† In brief, Thoreau believed that we should be ruled by conscience instead of the inexpedient government which had no conscience. Besides, we should do something to stop the â€Å"machine.† Thoreau believed that we should fight against injustice through non-violence, instead of being neither acquiescent nor using physical violence. â€Å"Let your life be a counter-friction to stop the machine.† This meant that we should stop the government and corporations that had no conscience.
