The narrative starts out with inquiries that have two possible solutions. We besides see this at the terminal of narrative when Lord Singleworth gives the two delegates the tally about as to the reply of the stake. From the inquiries asked in the first paragraph, we know that Lord Singleworth is a distinguished member of society. He is a rich, intelligent, and an aeronautic scientist who seemingly is non excessively fond of Venice. Throughout the full narrative, he contrasts between the beauty of the metropolis with something that is despicable. For illustration, he describes the beautiful architecture of many edifices in the metropolis. Then he talks about how dead the H2O is below the metropolis. We will write a custom essay sample on Lord Singleworth or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The writer is besides non fond of the Venetian people. Throughout the narrative, he says they gossip and speculate upon what he is making in the balloon. He besides talks about how the people # 8220 ; accept an reading which is apparently so undependable, # 8221 ; that it reaches # 8220 ; the ultimate bounds of local popularity. # 8221 ; It even reached the public talker Sir Toni di Bona. Norwid describes this individual as a harlequin, who has a lisp, and is fleshy. He even labels him a buffoon who makes upper category Venitians laugh by utilizing lower category wit, which is yet another struggle between cleanliness and uncleanness. He knows about the guesss of the people in Venice sing Lord Singleworth and his experiments, and chooses to support him. I believe Grazia defends Lord Singleworth merely to do money because at the terminal of his public presentation wealthy ladies had their retainers give money to the talker. The narrative is told in the first individual point of po sition. Although the individual # 8217 ; s name neer appears in the narrative, it is a 3rd delegate. The first delegate is Count Antonio della Brenta. He believes Lord Singleworth is up to some mischievousness whenever he goes up in the balloon. The other character is Signor di San Luca who is a doctor. He believes that Lord Singleworth goes up in the balloon merely to acquire fresh air. This is yet another reference of how the Venetian H2O odors so disgusting that it makes people ill. Both Count Antonio della Brenta and Signor di San Luca made a stake as to what Lord Singleworth really does in the air. Then the three of them ask to see Lord Singleworth to happen out the reply. The following twenty-four hours Lord Singleworth responds by stating that the metropolis with all it # 8217 ; s fancy constructions is built upon a # 8220 ; system of latrines. # 8221 ; He farther goes on and says that the hierarchy â€Å"must degrade a battalion of people, doing them animals without a sense of odor or any societal grace.† Here is yet another struggle between the hierarchy and the lower category. Lord Singleworth continues speaking about the uncleanliness of a lady dumping out her refuse from an flat window. Harmonizing to Lord Singleworth if she were to dump out her refuse from his balloon manner up in the air, she would non lend to the uncleanliness of the metropolis because at a higher lift there is merely cleanliness and that waste would vanish. Lord Singleworth continues by unwittingly stating that the talker Toni di Bona Grazia is responsible for distributing the rumours about his balloon and the falling piece of paper from the sky. This accusal may be true because Toni di Bona Grazia needs rumours so that he can gain from addresss supporting Lord Singleworth. Overall this narrative leaves the reader frustrated. Norwid begins his prose with several inquiries to which he does non reply, and leaves us hanging in the terminal. This is the type of narrative in which the scene is the most indispensable. There are many contrasts between the two societal categories and the beautiful metropolis built straight over a cloaca system. This narrative is symbolic with many societal, political and philosophical elements. The size of the narrative is decidedly kept to a minimal since there are many unreciprocated inquiries about some of the inside informations. However, Norwid seems to obtain his coveted consequence by speaking about the Venetian society and the struggles within it. The rubric of the narrative still keeps the reader in suspense since some of the inside informations are unreciprocated. It besides lets the audience know that the narrative focuses upon the events in one adult male # 8217 ; s life. The flood tide of the narrative is when the three delegates eventually confront Lord Singleworth with their conflicting sentiments about his behavior while he is up in the balloon. One delegate believes he is making experiments. Whereas, the other delegate feels he is up at that place for the exclusive intent of acquiring fresh air to help digestion. Overall, the secret plan is weak and solely focal points upon detecting what Lord Singleworth really does in his balloon. Lord Singleworth partly answers this inquiry by stating at higher lifts the air is fresher and cleaner, but at the same clip he besides takes his helper with him who likely does carry on experiments. Therefore, there neer truly is a declarati on to the balloon quandary and the reader is unsure as to the existent cause of Lord Singleworth # 8217 ; s behaviour and the logical thinking behind it.

Microscope observation of animal and plant cells Essay Example

Microscope observation of animal and plant cells Essay Example Microscope observation of animal and plant cells Essay Microscope observation of animal and plant cells Essay Cells represent the make up of our being as well as many other organisms whether they are unicellular or multicultural. Cells can also be complex or quite simplistic in design and contents, depending on the purpose of its function in an organism. Typically when studying cells some form of magnifications must be used to see the finest details of the cell, microscopes are used due to constraints in human eyes that only allow us to see to so much. In essence their use is to see what the eye cannot. This may include processes such as mitosis, phagotycosis and other forms of transport within the cell. Even though microscopes aid in viewing cellular content what can be seen my be limited due to the sizes of the actual organelles, or the types of stains used to highlight organelles within the cell. For example mitochondria cannot be seen with a standard lab light microscope. When scientist want to view the contents of a cell there are 2 main types of microscopes they use Light and Electron. All depending on the budget they have and the detail needed will determine which they would use. In this experiment we will make use of the light microscope.  Method  As per schedule until the cell is stained with Eosin, which instead of 2 minutes it was left for 20 seconds. Apart from this alteration the method is as per schedule Results  In this experiment we were not looking for actually results of tests, but here are the findings from viewing the microscope.  Cheek cell  Onion  Stomata.  All of the specimens where viewed under x100 magnification, this is achieved by the lenses on the eye piece producing x10 and then the objective lenses producing an additional x10 with in turn give x100 magnification.  Discussion  The focus of this practical involved making use of epithial tissue in animals and surface tissue in plants. There are different types of epithial cells the ones from the cheek cell are squamous epithelial cells. They form the epithial tissues that are continuous sheets, which cover most structures or cavities within the body.i Due to the limitations of the light microscopes, we are only able to observe some of the organelles within the 3 structures we viewed. To do this it involved making use of dyes to make parts of the cells visible. The two stains used were Haematoxylin and Eosin these are commonly referred to as HE stain. They are blue and red respectively. They both have separate functions and are used in conjunction to indentify different parts of the cell.  Haematoxylin is known as the basic stain as it identifies acidic material within in cells by turning them blue. Such structures include nucleic acid and nuclear material. These are then referred to as basophilic although some scientist debate on the use of the word.ii The counter part of haematoxylin is eosin, in opposition it is acidic and turns basic material within the cell red or a pink colour, depending on the concentration of eosin used. Parts of the cell thats are affected by eosin include the cytoplasm, because of its basic nature.  Haematoxylin is not really regarded as an actually a dye although this is debatable by some, where as eosin is an acid dye. Haematoxylin is able to develop colour-like properties when oxidized. Because of their different properties they both sow their importance in staining because of their characteristics.  As stated within the practical organelles were limited to what could be seen with the light microscope. An electron microscope would have highlighted organelles such as Golgi body, mitochondria etc. in three dimensions. Reference: Barbour, M. et al. (1997) Biology.

Employee Voice Mechanisms and Their Outcome Essay

Employee Voice Mechanisms and Their Outcome - Essay Example The paper tells that employee participation is the extent to which the employees are involved in the decisions of the company. This might include joint meetings, bargaining as a group and representation of workers on the board, but all the power lies with the management only. Therefore Rose comments that Employee voice covers, "a wide range of processes and structures which allow and even empower employees, directly or indirectly, to contribute to decision making within the organization". Further, into it, the discussion will cover aspects of voice mechanism in detail and how the current methods of voice have changed. Also, the various outcomes of such voice mechanisms for the workers will be dealt with. Finally, Legal changes and methods of improvement will also be discussed. In the early part of the twentieth century, the management of the working class by F.W. Taylor took a very controlled approach, particularly in the field where the workers had to be divided into their specializ ations. To keep a check on the functioning’s of these employees the management engaged a number of hierarchical roles of authority so as to maintain discipline, order, efficiency and to inculcate within them a sense of duty and not to oppose the management in its decisions. Increased competition and technological complicacies require higher skills and a commitment strategy. So accordingly nowadays, the workforce jobs are designed to include the functions of the firm and include severe of planning. The focus shifted from self to the performance of the team, that is, shared goals and technical know how. Standards need to be improved by and by and the company considers the efficiency of the group. Also very important is the matter of giving the employees an assurance or a security that they would be heard on various issues.

The Lamb and the Tyger Analysis

The Lamb and the Tyger Analysis William Blake was an 18th century visionary, poet, mystic, and artist. Blakes romantic style of writing allowed him to create contrasting views as those in The Lamb and The Tyger. From a young age Blake used his imagination that was frowned upon and unfortunately was never greatly appreciated during his lifetime. William Blake believed that it was the chief function of art to reveal the truth of the spiritual world by liberating imagination (Bowman 53). It wasnt until after Blakes death that his work finally received some attention. Known as a romantic, Blake continued throughout his writing to radically question religion and politics; He was very critical of the church, putting forth the effort to attack and question it. Blake put his own insight into his poems to raise the public awareness in a personal attempt to seek the truth. Perhaps he is most famous for his creative and simplistic Songs of Innocence and Songs of Experience that influenced the other Romantic poets with themes of good and evil, heaven and hell, and knowledge and innocence. With regards to religion, William Blake opposed the views of the Christian church and its standardized system. Blake, having more of a spiritual position than a religious one, considered himself as a monistic Gnostic, meaning that he believed what saved a persons soul was not faith but knowledge (Harris 1). Blakes view of religion was considered blasphemous, and in his works he was concerned with the character of individual faith than with the institution of the Church, its role in politics, and its effects on society and the individual mind (SparkNotes Editors 1). Blakes The Lamb and The Tyger is more suggestive to the nature of God. The idea is that the same God who made the lamb also made the tiger, so unless it is suggested that God created evil, then the tiger must not be evil. The fact that the same God created both the lamb and tiger suggest that they just represent two different sides of God: Two different aspects of existence. Blakes perception of good and evil isnt just one extreme to the other, instead, the ambiguity of evil isnt evil; it is just the other side of good. Blake technically didnt believe in a dichotomy, the division into two usually contradictory parts or opinions. Blake portrays his argument that a human being cannot be completely good or completely evil. This trait does not exist within human beings, and therefore does not exist in God. The other writers and minds of the 18th century were mainly deists, the belief based solely on reason. They did not show interest in the nature of God as Blake did, instead, reason was their god. In the poem The Lamb, William Blake incorporates his unique style through the use of religious symbolism, creative lines, and simple patterns. The Lamb was a part of a series of poems called the Songs of Innocence that was published in 1789. Poems that were more simplistic in style and nature became more contrition and prophetic in Songs of Experience. Through simplistic structure, he chose the narrator of a child, as in this poem, told through childlike eyes, speaking of the innocence in all of human life, and that the lamb is Christ, marveling over Gods creations. The dramatic perspectives and continual allusiveness of the lyrics in The Lamb have shown to be a key factor in Blakes writing and have been interpreted and reinterpreted by critics and readers ever since Blakes death. Blake utilizes his rhetoric genius by symbolically expressing the appearance of the lamb to that of the nature of God. Within the poem, Blake brings up an interesting concept by stating, He is called by thy name / For he calls himself a Lamb, the lamb not only suggest innocence and the meaning of life, but at the same time conveys the theme that Christ is the lamb (Blake 662). The poem comments on how he is meek and he is mild, thus giving God the characteristics of goodness and purity (Blake 662). This gives a varying contrast to Blakes poem The Tyger as it advocates the speculation of evil. William Blakes, The Tyger, is the poetic counterpart to the Lamb of Innocence from his previous work, Songs of Innocence, thus creating the expression of innocence versus experience What immortal hand or eye / Dare frame thy fearful symmetry (Blake 770). The Tyger is part of the continued series of lyrics titled Songs of Experience that was published in 1794, as a response to the Songs of Innocence. The Songs of Experience are interpreted as the child, conveyed in Songs of Innocence, matures to adulthood and is molded by the harsh experiences and negative forces that reality has on human life, thus shows the destructiveness of the tiger. Blake utilizes his deceptively complex ideas, symbolism, and his allusiveness to portray the essence of evil in The Tyger. Blake uses tyger instead of tiger because it refers to any kind of wild, ferocious cat. The symbolism of the hammer, chain, furnace, and anvil all portray the image of the blacksmith, one of the main central themes in this poem ( Blake 769). William Blake personifies the blacksmith to God, the creator, and Blake himself. The Tyger is about having your reason overwhelmed at once by the beauty and horror of the natural world (Friedlander 1). When the stars threw down their spears / And waterd heaven with their tears (Blake 770). For Blake, the stars represent cold reason and objective science (Friedlander 1). In retrospect, the creation of the tiger represents transcendent mystery and direct reference to the lamb Did he who made the Lamb make thee (Blake 770). The Lamb and the Tyger are polar opposites of each other, one representing the fear of God and the other representing faith or praise of God through nature. As a child one is more like the lamb, innocent and more pure, and as they mature they earn their stripes and become aged and mature by societal tendencies of life like the tiger. The irony in the Songs of Innocence in contrast with the Songs of Experience is that they are opposites but seem to bounce off one another. They both have the same creator, both God and Blake, and suggest morals of good and evil. They are each on the extreme ends of the spirituality spectrum and in the middle is humanity, but you cant have one without the other. In order to have good you have to balance it out with evil, in a sense where good isnt just good, it is the other side of evil, and where evil is the other side of good.

Depression :: Health, Nursing, Long Term Care

Evidence suggests that depression is associated with high levels of morbidity and mortality and adversely affects the quality of life and social functioning (Katona, 1994). Some of these patients do not move about much, and with depression added to this premise, the transition from what these patients were used to, to a completely new environment is usually traumatic. Nursing care providers can ease the trauma felt by these new arrivals by conducting assessments to determine whether these individuals are suffering from depression, so as to remedy this malady as soon as possible. Depression affects approximately 5% of the population at any one time, with depressive symptoms being more common in people over 65, with prevalence estimates ranging from 10 to 15% (Baldwin, 1995). Depression in nursing homes has been recognized as especially problematic states Ames, (1994). Depression is not a normal consequence of aging, and it is known to be under-recognized and under-treated, especially in hospitals, outpatient settings, and nursing homes. (Patry, 2004). Problem Background Older people entering long-term care facilities face major adjustment challenges and are particularly vulnerable to mental health problems (Murphy, 1982; Mikhail, 1992; Manion & Rantz, 1995). Newly admitted residents in long-term care facilities are particularly vulnerable to depression and the early recognition and treatment of depression is therefore crucial around the time of admission to a home. (Bagley et al., 2000). By day 14 of their nursing home stay, thirty-eight percents of the admitted residents sampled in a study conducted by Boyle et al. (2004) were positive for depressive symptoms. Depression then is still a highly significant problem among those admitted to a nursing home. (Boyle, 2004). In contrast, the authors’ stated that depression recognition in the nursing homes has improved. Michigan's Quality Improvement Organization (MPRO) conducted a study of 14 nursing facilities to improve the accuracy of assessments, targeting, and monitoring of care. 69% of participants were female 46% were 76-85 and 37% were 86 or older. Among men, 24% were age 75 or younger 51% were 76-85 and 25% were 86 or older. It was found that out of 818 residents, 313 (38%) had depressive symptoms by day 14. Out of the 313, 213 (68%) were admitted with a diagnosis of depression. (Boyle, et al., 2004). The nursing homes in this study use the Geriatric Depression Scale (GDS) to assess symptoms of depression; however, its use is highly selective. (Boyle, et al., 2004). The authors stated that additional research in developing strategies to ensure continuity of care to people across treatment settings would be useful.

Da Vinci’s Mona Lisa and Warhol’s Marilyn Monroe Paintings Essay

Leonardo DaVinci’s Mona Lisa is one of the most well-known paintings in the world. Show anyone from a 60 year old man to a 10 year old girl a picture of the painting and, most likely, they will be able to name the painting as well as the painter. While some say that DaVinci’s painting is the most famous of all created, many of Andy Warhol’s paintings are also easily recognizable. Almost everyone has seen the Campbell’s Soup Can series Warhol painted or his famous Triple Elvis print. This paper will be focusing on his Marilyn Monroe series, which I will be comparing and contrasting to the Mona Lisa. There are many obvious differences between the two paintings, such as the time period, color scheme, background and subject matter. My goal is to also point out some similarities such as their use of line, recreations, fame, and prominence in society. One of the major contrasts between the two works is the history behind the paintings. Andy Warhol was said to be fascinated with the actress Marilyn Monroe’s supposed suicide in August of 1962. Warhol proved the Proverb, â€Å"Good men must die, but death cannot kill their names† to be true, making his Marilyn Monroe series one of his most famous works. Warhol bought a publicity still of Marilyn’s 1953 movie Niagara, cropped it, enlarged the face, and reproduced it on eight different canvases. Each painting was given a different color scheme. These paintings were the first solo exhibition for Warhol. The most famous of the series, Lemon Marilyn, was bought and kept in a private collection until 2007. While the subject of Warhol’s painting is very well known and easily recognized, the subject of Leonardo DaVinci’s Mona Lisa was most likely commoner, and there are many different theories of who the woman could be. Some say the woman is DaVinci himself, in woman form. Others say it could be Lisa Gherardini; the wife of a wealthy businessman in Florence, Italy named Francesco Del Giocondo. DaVinci was commissioned to paint the Mona Lisa in 1503, and worked on it for four years before it was finished. DaVinci kept his painting for quite a while before he sold it to the King of France, King Francois, in 1516. (â€Å"Mona Lisa.† Lairweb.com. N.p., n.d. Web.) After the French Revolution, the painting was moved to the Louvre, where it remains today. The history behind the paintings also point out several more differences. There is only one Mona Lisa, while Warhol created many Marilyn paintings. The time period when the two painters lived was decades apart. DaVinci was alive from 1452-1519, while Warhol was born in 1928 and died in 1987. While Warhol was strictly an artist, DaVinci spent time as a mathematician, engineer, writer, and geologist as well. The two men’s styles of painting were very different as well. DaVinci painted in the style of chiaroscuro, the use of strong contrasts between light and dark, and sfumato. Sfumato is created by painting a color that turns slowly from light to dark tones to give off a kind of misty glow or smoky mystery. Andy Warhol was a major part of the Pop art movement. Jennifer Rosenberg of About.com quoted pop art as being, â€Å"a new style of art that began in England in the mid-1950s and consisted of realistic renditions of popular, and everyday items.† (Rosenberg, Jennifer. â€Å"Andy Warhol.† About.com 20th Century History. About.com, n.d. Web. 16 Dec. 2012.) Warhol used silk-screening to create Marilyn Monroe. Warhol is quoted as saying, â€Å"In August 62 I started doing silkscreens. I wanted something stronger that gave more of an assembly line effect†¦you pick a photograph, blow it up, transfer it in glue onto silk, and then roll ink across it so the ink goes through the silk but not through the glue†¦ I was thrilled with it. When Marilyn Monroe happened to die that month, I got the idea to make screens of her beautiful face the first Marilyns.† (â€Å"Andy Warhol’s Marilyn Prints.† Andy Warhol’s Marilyn Prints. Color Vision and Art, n.d. Web. 16 Dec. 2012.) DaVinci’s painting was progressive for the time. The traditional paintings of his time were of a head and shoulders portrait, in a very rigid or posed position. The Mona Lisa is painted all the way down to her hands, and she seems to be in a very comfortable, relaxed pose. Her pose is very linear, which conveys a sense of â€Å"formal and dignified ideas†. (ROEMER, CK. â€Å"Looking at Great Art Practice.† Http://www.studiocodex.com. N.p., 2007. Web.) This would be appropriate if this woman is the wife of a wealthy man, which is one of the speculations of the woman’s identity. Andy Warhol’s painting, on the other hand, seems almost regressive. Only Marilyn’s face is shown. She is depicted with a very serious expression, and is very unnaturally posed. This seems to project a sense of excitement or disorder, which represent Marilyn’s life very accurately. The two subjects of the painting are very different in appearance as well. The Mona Lisa has no makeup on. She is dressed very plainly and does not seem to be wearing any jewelry. Marilyn Monroe has a lot of make-up on and has her hair curled and styled. Marilyn seems to have a haughty or annoyed expression on her face, while Mona Lisa is smiling slightly and seems to be happy and content. Another major difference between the two paintings is the use of color. The Mona Lisa is depicted in very earthy tones. The tan color of the flesh seems closer to the viewer, while the muted browns, greens, tans, and blues seem to fade into the background. DaVinci used light and dark colors to highlight certain parts of the painting, such as the woman’s face and hands. The color palette is what would be expected if this was an actual photograph. Andy Warhol’s Marilyn is the complete opposite of the Mona Lisa. None of the colors are natural, except, maybe, the makeup, and can appear shocking to the eye at first glance. All aspects of the painting are bright; eyes, lips, eye shadow, and hair. Warhol painted Marilyn in ten different color combinations with 250 of each color variation. (Henry. â€Å"Henry On Pop Art.† ‘Henry On Pop Art’ N.p., 08 Aug. 2011. Web. 16 Dec. 2012.) While the actual colors used in the paintings are very different, the way the painters used the colors brings out a similarity in the two. Mona Lisa is dressed very dark and her pale face is framed by dark hair. The light colors used in the background seem to bring the woman to the front of the painting. This was most definitely done on purpose by DaVinci. He wanted the viewer to focus on Mona Lisa. The same can be said of Warhol. He uses a bright contrasting color for his background of Marilyn Monroe. Although the background color almost always matches that of Marilyn’s eye shadow, the background contrasts with the rest of the painting, bringing the face towards the viewer. The use of line in both paintings is also similar. No brush strokes are visible in either painting, and appear a bit foggy. The Mona Lisa is this way due to the technique, sfumato, discussed earlier. In Marilyn, it is hard to pick out a defined line in her hair, for example. The lines in DaVinci’s paintings are the same, flowing from one to the other. The Mona Lisa is blended so well that each section seems like a part of the next. The background of the Mona Lisa is a landscape with a river, bridge, trees, grass, and mountains. The view seems to go on forever, and there is no real focal point in the background. The backgrounds purpose in this painting in unknown, some say it is to contrast the peaceful look of the woman with a foreboding background. Others think it could have been as simple as DaVinci practicing with landscapes. Unlike Mona Lisa, the backgrounds of the Marilyn Monroe paintings are a solid color. The background contrasts dramatically with the colors in the actual face. The background pulls the viewer’s eye to Marilyn’s face, instead of something that could be happening in the background. Symmetry is another example of a way the two paintings are alike. The shape of the Mona Lisa is very symmetrical. The woman is sitting straight and a straight line down the middle of the painting would show equal parts. The woman’s body is a triangular shape, with the tops of her legs and hand forming the base, and her head becoming the point. Her face is very circular, and the smile she displays is an arch of a circle. (Roemer, CK. â€Å"Looking at Great Art Practice.† Http://www.studiocodex.com. N.p., 2007. Web.) Warhol gives his Marilyn Monroe paintings a subtle heart shape with the curves created by her hairline. The painter, like DaVinci, uses simple shapes as well, such as the half-moon of her eye shadow, or the slight triangles of her eyebrows, which also shows symmetry. DaVinci creates a feeling of depth and space in his painting. The fact that the woman is taller than the mountains in the background suggests that she is seated very close to the viewer, while the mountains are in the distance. The detail of the pleats in her skirt, the individual pieces of hair, and transparent veil that covers her head are small details that make the woman seem closer to the viewer. The walking paths and streams of water leading up the painting make the eye move upwards, and form a sense of continuous forest. The viewers understand that the landscape goes on for quite a while. (Roemer, CK. â€Å"Looking at Great Art Practice.† Http://www.studiocodex.com. N.p., 2007. Web.) In contrast to DaVinci, Warhol used space by placing Marilyn’s face in the middle of the painting. There is no real use of depth in this painting, because of the plain, contrasting color background. She almost appears to be completely flat against the surface. The eye is immediately drawn to the face in Marilyn Monroe. As mentioned above, the contrasting background color pulls the face forward, making the viewer notice her first. The same can be said of Mona Lisa, making focal point a similarity of the two. The woman in Mona Lisa is the biggest part of the painting. Her pale face offset by her dark hair and clothes draws the viewer’s eye to her. The position of her hands is right below her face, which also serves as a line to the focal point. The use of texture is somewhat absent from Warhol’s painting, while the Mona Lisa is full of texture, another difference in the paintings. The folds in the woman’s dress make the painting seem more realistic, while the uneven and sharp edges of the mountains in the background contrast nicely with the smoothness of the woman’s face and hair. The woman’s skin also has a dotted affect which makes it seem more lifelike, instead of Warhol’s Marilyn that seems fake and unrealistic. The use of value plays a huge role in both paintings. DaVinci uses abrupt changes in value; The pale skin of the woman face and hands against her dark hair and dress. He uses the same type of changes to show the wrinkles on the fabric of her clothing. (ROEMER, CK. â€Å"Looking at Great Art Practice.† Http://www.studiocodex.com. N.p., 2007. Web.) Andy Warhol uses value changes in the brightness of Marilyn’s hair against the darker background. The black tones used underneath her hair are darker than the color of her somewhat pale skin. Another similarity is the massive amounts of recreations or paintings based on the same subject. Many artists has done their own version of the Mona Lisa, making her their nationality, fat, and even making her another person altogether. Many artists have also taken Marilyn Monroe and painted her their own way. Both paintings still play a huge role in society today. You can buy phone cases, laptop skins, and even clothing with a picture of these paintings. Replicas of both paintings can be seen hanging on walls of homes, restaurants, and art galleries. Mona Lisa and Marilyn Monroe are both easily recognized and correctly identified in today’s society. A final similarity between the two paintings is the significance they both played in their style of art. Leonardo DaVinci’s Mona Lisa is said to have â€Å"become the prototype for Renaissance paintings.† (Lorenzzi, Rosella. â€Å"Mona Lisa.† Mona Lisa. N.p., 16 Jan. 2008. Web. 16 Dec. 2012.) Andy Warhol was affectionately known as the â€Å"Pope of Pop†, and his Marilyn Monroe series came to be one of the most well-known and popular works of pop art in his time. The final difference between the two, and most interesting, is that Warhol recreated DaVinci’s Mona Lisa in his own style; putting 30 Mona Lisas in one silk screen. Warhol is quoted as saying â€Å"30 is better than 1.† (Rose, Millie. â€Å"Postmodernism.† : Andy Warhol. N.p., 08 Nov. 2010. Web. 16 Dec. 2012.) The Mona Lisa is said to have been a major inspiration to Warhol, and he was honored to be able to have his own spin on this iconic painting. Obviously Warhol’s w ork did not influence DaVinci because of the time frame. While the differences far outweigh the similarities, both paintings are brilliant. Warhol was a major influence in the pop art world, and his paintings are still being used in many forms of advertising today. DaVinci is said to have been the ultimate example of what a portrait should be, and without a doubt, he has influenced many of the other famous painters today. Both men, while their styles couldn’t have been anymore different, have two of the most famous names in the art world. * Esaack, Shelly. â€Å"Lemon Marilyn, 1962.† About.com Art History. N.p., n.d.

The Dark Side of Application.ProcessMessages

The Dark Side of Application.ProcessMessages Article submitted by Marcus Junglas When programming an event handler in Delphi (like the OnClick event of a TButton), there comes the time when your application needs to be busy for a while, e.g. the code needs to write a big file or compress some data. If you do that youll notice that your application seems to be locked. Your form cannot be moved anymore and the buttons are showing no sign of life. It seems to be crashed. The reason is that a Delpi application is single threaded. The code you are writing represents just a bunch of procedures which are called by Delphis main thread whenever an event occured. The rest of the time the main thread is handling system messages and other things like form and component handling functions. So, if you dont finish your event handling by doing some lengthy work, you will prevent the application to handle those messages. A common solution for such type of problems is to call Application.ProcessMessages. Application is a global object of the TApplication class. The Application.Processmessages handles all waiting messages like window movements, button clicks and so on. It is commonly used as a simple solution to keep your application working. Unfortunately the mechanism behind ProcessMessages has its own characteristics, which might cause big confusion! What does ProcessMessages? PprocessMessages handles all waiting system messages in the applications message queue. Windows uses messages to talk to all running applications. User interaction is brought to the form via messages and ProcessMessages handles them. If the mouse is going down on a TButton, for example, ProgressMessages does all what should happen on this event like the repaint of the button to a pressed state and, of course, a call to the OnClick() handling procedure if you assigned one. Thats the problem: any call to ProcessMessages might contain a recursive call to any event handler again. Heres an example: Use the following code for a buttons OnClick even handler (work). The for-statement simulates a long processing job with some calls to ProcessMessages every now and then. This is simplified for better readability: {in MyForm:}   Ã‚  WorkLevel : integer; {OnCreate:}   Ã‚  WorkLevel : 0; procedure TForm1.WorkBtnClick(Sender: TObject) ; var   Ã‚  cycle : integer; begin   Ã‚  inc(WorkLevel) ;   Ã‚  for cycle : 1 to 5 do   Ã‚  begin   Ã‚  Ã‚  Ã‚  Memo1.Lines.Add(- Work IntToStr(WorkLevel) , Cycle IntToStr(cycle) ;   Ã‚  Ã‚  Ã‚  Application.ProcessMessages;   Ã‚  Ã‚  Ã‚  sleep(1000) ; // or some other work   Ã‚  end;   Ã‚  Memo1.Lines.Add(Work IntToStr(WorkLevel) ended.) ;   Ã‚  dec(WorkLevel) ; end; WITHOUT ProcessMessages the following lines are written to the memo, if the Button was pressed TWICE in a short time: - Work 1, Cycle 1 - Work 1, Cycle 2 - Work 1, Cycle 3 - Work 1, Cycle 4 - Work 1, Cycle 5 Work 1 ended. - Work 1, Cycle 1 - Work 1, Cycle 2 - Work 1, Cycle 3 - Work 1, Cycle 4 - Work 1, Cycle 5 Work 1 ended. While the procedure is busy, the the form does not show any reaction, but the second click was put into the message queue by Windows. Right after the OnClick has finished it will be called again. INCLUDING ProcessMessages, the output might be very different: - Work 1, Cycle 1 - Work 1, Cycle 2 - Work 1, Cycle 3 - Work 2, Cycle 1 - Work 2, Cycle 2 - Work 2, Cycle 3 - Work 2, Cycle 4 - Work 2, Cycle 5 Work 2 ended. - Work 1, Cycle 4 - Work 1, Cycle 5 Work 1 ended. This time the form seems to be working again and accepts any user interaction. So the button is pressed half way during your first worker function AGAIN, which will be handled instantly. All incoming events are handled like any other function call. In theory, during every call to ProgressMessages ANY amount of clicks and user messages might happen in place. So be careful with your code! Different example (in simple pseudo-code!): procedure OnClickFileWrite() ; var myfile : TFileStream; begin   Ã‚  myfile : TFileStream.create(myOutput.txt) ;   Ã‚  try   Ã‚  Ã‚  Ã‚  while BytesReady 0 do   Ã‚  Ã‚  Ã‚  begin   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  myfile.Write(DataBlock) ;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  dec(BytesReady,sizeof(DataBlock)) ;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  DataBlock[2] : #13; {test line 1}   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Application.ProcessMessages;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  DataBlock[2] : #13; {test line 2}   Ã‚  Ã‚  Ã‚  end;   Ã‚  finally   Ã‚  Ã‚  Ã‚  myfile.free;   Ã‚  end; end; This function writes a large amount of data and tries to unlock the application by using ProcessMessages each time a block of data is written. If the user clicks on the button again, the same code will be executed while the file is still being written to. So the file cannot be opened a 2nd time and the procedure fails. Maybe your application will do some error recovery like freeing the buffers. As a possible result Datablock will be freed and the first code will suddenly raise an Access Violation when it accesses it. In this case: test line 1 will work, test line 2 will crash. The better way: To make it easy you could set the whole Form enabled : false, which blocks all user input, but does NOT show this to the user (all Buttons are not grayed). A better way would be to set all buttons to disabled, but this might be complex if you want to keep one Cancel button for example. Also you need to go through all the components to disable them and when they are enabled again, you need to check if there should be some remaining in the disabled state. You could disable a container child controls when the Enabled property changes. As the class name TNotifyEvent suggests, it should only be used for short term reactions to the event. For time consuming code the best way is IMHO to put all the slow code into an own Thread. Regarding the problems with PrecessMessages and/or the enabling and disabling of components, the usage of a second thread seems to be not too complicated at all. Remember that even simple and fast lines of code might hang for seconds, e.g. opening a file on a disc drive might have to wait until the drive spin up has finished. It doesnt look very good if your application seem to crash because the drive is too slow. Thats it. The next time you add Application.ProcessMessages, think twice ;)

Global Warming Most of the world today regards the â€Å"global warming† as both real and dangerous. Many aspects, however, have already been discounted by the scientific community. Fears of massive sea level increase, accompanied by many early discussion about global warming. Scientist afraid the sea level would increase onto land due to the melting of ice. It is now widely agreed that even the potential contribution of warming to sea level rise would be swamped by other more important factors (Moran, 1999). These factors include hazardous gases and pollutants. We are entering a period of global warming as a result of burning vast amounts of fossil fuels. By burning fossil fuels, â€Å"we are putting into the air more gases that act like a globe of glass around the planet† (National Geographic, 1990). The ‘globe of glass’ is a mixture of all the fuels that remains permanently on the surface of Planet Earth. It is called glass because it prevents cooling air from entering causing the Green House Effect. Many scientists believe that human processes are contributing to global warming regardless of impact of natural cycles also causing climate change (Keller, 1999). The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases – primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’s climate responds to these gases, global temperatures are rising. Scientists on Hawaii’s Mauna Loa have recorded steady increase in human activities such as burning fossil fuels. Most believe that the rising CO2 level will lead to higher global temperatures and significant climate change (National Geographic, 1990). Some scientists do not be...

Forensic Science - Case Study Example Since his execution, his parents and relatives have been striving to show the world the misuse of justice evident in the case because they still trust that their son was not guilty of the crime. Various articles and books have been published with respect to the case of James Hanratty, with some supporting the fact that Hanratty was not guilty following their investigation and the medical reports that were using the DNA of the victim and those of the deceased. For one to better understand the investigations and the trial that was conducted on Mr. Hanratty, it is essential to consider the criminal record of the individual prior to the case that led to his death. It can be retrieved from the criminal accounts of Hanratty that by the period when he was found guilty of murdering Michael Gregsten, he has already been convicted of four crimes that were linked to motoring offences and minor theft such as housebreaking. In atatininig seventeen years of age, Mr. Hanratty appeared before Harrow Magistrate for taking someone’s motor vehicle without authority, and also driving a vehicle without insurance or a driving license. Such led to Hanratty being introduced to psychiatric treatment at the Portman Clinic where he was treated as an outpatient. At the age of eighteen years, Hanratty appeared before the court at the county of Middlesex Sessions where he was found guilty and sentenced to two years of imprisonment due to breaking in into someone’s house and stealing some property.

TypeWriter Essay Example | Topics and Well Written Essays - 1750 words

TypeWriter - Essay Example Creativity and innovation that leads to technological advancement started a long time ago. The form of communication among people and especially leaders in the 1500s was through writing. The quest to achieve more efficiency in writing led to the invention typewriters in 1860s. A typewriter is a machine that can be mechanical or electromechanical used in creating characters on a piece of paper. The technology on a typewriter involves transfer of ink or carbon impression on a set piece of paper by striking characters on a key-board. Keys are attached to type bars that are in a circular basket under the platen. Striking hard the keys transfers a marking on the molded head of the type bar. The paper used in the process is wrapped around a cylinder that mounted on a carriage. The carriage moves after striking a type bar to allow the specific spacing of words and letters. The keyboard is organized in a manner to make it easier for the operator to type the characters. After the invention, the machine become popular and was used in different areas such as homes, by writers, and offices to create writing on paper for different purposes. The increased use of the typewriters came to a halt in the early 1980s when word processor in a computer became popular due to its efficiency compared to a typewriter. However, the typewriters have not been completely wiped out. Different places of the world such as India and certain parts of Africa are still using the machine. The machine has undergone a series of changes all with the aim of improving it proficiency in serving the intended purpose. Earlier innovations and trials had been made regarding the creation of a printing device, but the first successful typewriter was made by Sholes and Glidden in 1870. It was known as the Remingtons typing machine. The intended purpose of the machine was to ensure legal documents produced were neat, legible, and of a standard format. Creativity in this machine
