Recognizing Impressionistic Art essays

Recognizing Impressionistic Art essays In terms of style it is relatively easy to recognize an Impressionist painting. There are certain characteristics that make this form of art stand out, such as the rough brush strokes and colors that often tend to blend into one another. However, in order to identify an Impressionist painting, who has to be aware of the underlying philosophy and intention of this style of art. In essence Impressionism was both a new style in the development of art and a new approach to the interaction between the artist and the subject. The most obvious characteristic that distinguishes an Impressionist painting from other styles and types of art can be derived from the word impression. The term Impressionistic was a description of this style which was intended as a critique by earlier critics. The first characteristic of an Impressionistic work of art is its deviance from the more objective and representational forms of art. The philosophy behind Impressionism was that the artist should capture a fleeing impression of nature; which was translated into art through a more casual and less photographic copy of nature or an object. Therefore an Impressionist painting is an attempt at creating a painting that captures the mood or feeling of a certain subject, rather than an exact copy. This also implies that Impressionistic art is more subjective in its approach and focuses on the interaction between the object being painted and the artists feelings or impressions. The Impressionists also tended to focus on scenes from nature, especially landscapes, and they tended to paint not in the studio but in the open air. In order to achieve these ideals the Impressionists used certain distinguishing techniques and this led to the artistic style that we associate with Impressionism. One of the first aspects that distinguish an Impressionist painting is the loose and short brush strokes. This is indicat...

The Difference Between Deflagration and Detonation

The Difference Between Deflagration and Detonation Combustion (burning) is a process by which energy is released. Deflagration and detonation are two ways energy may be released. If the combustion process propagates outward at subsonic speeds (slower than the speed of sound), its a deflagration. If the explosion moves outward at supersonic speeds (faster than the speed of sound), its detonation. While the action of deflagration is to push the air in front it, objects do not explode because the rate of combustion is relatively slow. Because the action of detonation is so rapid, however, detonations result in shattering or pulverizing objects in their path. Deflagration The definition of deflagration, according  to the Collins Dictionary is a fire in which a flame travels rapidly, but at subsonic speed, through a gas.  Deflagration  is an explosion in which the speed of burning is lower than the speed of sound in the surroundings. Everyday fire and most controlled explosions are examples of deflagration. The flame propagation velocity is less than 100 meters per second (usually much lower), and the overpressure is less than 0.5 bar. Because it is controllable, deflagration can be harnessed to do work. Examples of deflagrations include: internal combustion engine (used in any vehicle that uses fossil fuels such as gasoline, oil, or diesel fuel)gas stove (fueled with natural gas)fireworks and other pyrotechnicsgunpowder in a firearm Deflagration burns outward radially and requires fuel to spread. Thus, for example, a wildfire starts with a single spark and then expands in a circular pattern if there is fuel available. If there is no fuel, the fire simply burns out. The speed at which deflagration moves depends upon the quality of the available fuel. Detonation The word detonation means to thunder down, or explode. When a decomposition reaction or combination reaction releases a lot of energy in a very short span of time, an explosion may occur.  A detonation is a dramatic, often destructive form of an explosion. It is characterized by a supersonic exothermic front (in excess of 100 m/s up to 2000 m/s) and significant overpressure (up to 20 bars). The front drives a shockwave ahead of it. Although technically a form of oxidation reaction, a detonation doesnt require combination with oxygen. Unstable molecules release considerable energy when they split and recombine into new forms. Examples of chemicals that produce detonations include any high explosives, such as: TNT (trinitrotoluene)nitroglycerinedynamitepicric acidC4 Detonations, of course, can be used in explosive weapons such as nuclear bombs. They are also (in a much more controlled manner) in mining, road construction, and the destruction of buildings or structures.   Deflagration to Detonation Transition In some situations, a subsonic flame may accelerate into a supersonic flame. This deflagration to detonation is difficult to predict but occurs most often when eddy currents or other turbulence are present in the flames. This can happen if the fire is partially confined or obstructed. Such events have occurred in industrial sites where extremely combustible gasses have escaped, and when ordinary deflagration fires encounter explosive materials.

Sustainable Development (plan paper) Essay Example | Topics and Well Written Essays - 750 words

Sustainable Development (plan paper) - Essay Example During this period, as many as 12 distinct goals and 88 focus areas will be covered to develop sustainable initiatives. The NSDS has received strategic and monetary assistance from the United Nations Environment Program (UNEP), which has sought to help in the development of communities ravaged by the Tsunami in 2004 (ADB, 2005). Kenya has also embarked upon a comprehensive sustainable development (SD) plan aimed at protecting the country’s environment and natural resources. The SD plan was developed with the aim of providing relevant education to the masses in a bid to encourage local action. The SD has also gained prominence as Kenya had previously not given importance to tackling the threats affecting the environment and there have been delays on the part of the administration in understanding the link between environment and SD (Adzobu, 2008). The Kenyan SD plan gives primary importance to the protection of the biophysical dimension of the forests while there has been lesse r focus towards improving social and economic factors. The SD plan was developed further into the National Environment Action Plan (NEAP) in 2005, which considered the role of poverty, still a major challenge faced by the country, and the resulting socio-economic pressures on the government’s efforts to protect the nation’s natural resources. The NEAP has noted the importance of capacity building over the coming few years to tackle the various issues posed by technological, economic, social and political deficiencies. The role of education in this scenario has also shifted from a concern towards the physical environment towards popularizing the intricate interplay between human activities and the environment (Wood, 2007). SD is thus being introduced as part of the regular school curriculum and is taught to students belonging to the fifth grade and beyond. The first phase of the NEAP will be implemented up to the year 2010 and will be followed by a thorough performance review prior to the introduction of the subsequent phases (Wood, 2007). The primary similarity between the SD plans of Maldives and Kenya is their extensive focus on protecting the local environment, although several differences and variations exist. The strategy adopted by Maldives is aimed at stimulating local activities such that businesses can develop ecologically sustainable methods, people can reduce their dependence on non-renewable fuels and scarce land can be protected from submersion (Annandale, 2007). The NSDS has also introduced ways to protect the fragile coral reefs around the archipelago as a solution to protect the islands from rising sea levels. On the other hand, the SD plan developed by Kenya is aimed at protecting the country’s natural resources and biodiversity. The plan was developed and promoted by the Kenya Organization for Environmental Education (KOEE) and is thus considered as an internal project (Adzobu, 2008). In contrast, the NSDS of the Maldives has received considerable support from the UNEP through various mediums (ADB, 2005). Additionally, the SD plan is focused towards imparting relevant education within Kenyan schools and is thus a long-term initiative. The impact of the NEAP will thus require some time

How does Ernest Hemingway use elements such as light and dark to Research Paper

How does Ernest Hemingway use elements such as light and dark to foreshadows specific plot in his short story The Nick Adams Stories - Research Paper Example The character is romantically involved with a young girl Marjorie. He serves as a soldier and suffers from a knee wound just like Hemingway (â€Å"Character Analysis Nick Adams†). So in short Hemingway uses this fictional character Nick Adams to reiterate his life as a child and young man. He spent his youth serving in army. He has made this a part of his short stories. This autobiographical representation of events gives an insight into his mind that brings out the memories of his life and one can interpret the implications that he is trying to show in his text. Hemingway uses the elements of light and dark in his short stories to work as an important force that brings out the concerns in the text and plays an essential role in the narrative structure of the text. Arthur Miller in â€Å"Death of a Salesman† makes use of light to take the readers into the insight of the characters often revealing the important events or for foreshadowing. Miller often uses light to divide the stage for two different actions taking place at the same time. Similarly, Hemingway uses light in his texts but mainly for a different purpose. He makes use of the light as a technique of foreshadowing to develop interest and to highlight the prevailing or underlying themes. Hemingway in his short stories often uses light and darkness to bring out the thematic concerns of the text. His short stories are full of examples where he uses light and dark to foreshadow or to highlight the themes or motifs in the text. â€Å"The Indian Camp† presents an account of a young Nick who travels with his father on boat to an Indian Camp where Dr. Adams performs a Caesarean to deliver a baby boy. The use of light and dark in this story symbolizes the racial bias and foreshadows the personal growth of the protagonist. The darkness that prevails during the journey symbolizes Nick’s own lack of awareness. It foreshadows the bleak and grim reality of life that he is about to encounter when he will reach the

Epilepsy Essay -- Neurology Neurological Disorders Essays

Epilepsy Epilepsy is a very common neurological disorder. Some reports estimate that five in one-thousand people suffer from this problem. Throughout history, people with epilepsy have been shunned or considered inferior. Even today, ignorance leads many people to treat the epileptic as "abnormal" or "retarded". Although the etiology of epilepsy is still not fully understood, it is quite treatable due to advances in modern medicine. Epilepsy is characterized by uncontrolled excessive activity of either a part of, or all of the central nervous system. A person who is predisposed to epilepsy has attacks when the basal level of excitability of the nervous system rises above a certain critical threshold. As long as the degree of excitability is held below this threshold, no attack occurs. Basically, epilepsy can be classified into three major types: grand mal, petit mal, and focal or partial epilepsy. Grand mal epilepsy is characterized by extreme neuronal discharges in all areas of the brain: in the cortex, in the deeper parts of the cerebrum, and even in the brain stem and thalamus. Also, discharges into the spinal cord cause generalized tonic convulsions of the entire body, followed toward the end of the attack by alternating tonic and then spasmodic muscular contractions called tonic-clonic convulsions. Often the person bites or "swallows" the tongue and usually has difficulty in breathing, sometimes to the extent of developing cyanosis. Also, signals to the viscera frequently cause urination and defecation. The grand mal seizures lasts from a few seconds to as long as three to four minutes and is characterized by post-seizure depression of the entire nervous system; the person remains in stupor for one to many minute... ...l. 16: S31-S38.

Learning and education Essay

  Ã‚  Ã‚  Ã‚   Learning and education are some of the most prized assets any person could have. Many parents consider these assets to be the primary treasure which they can give to their children to face the challenges of the future. However, there are some instances in which education becomes unreachable due to some hindrances like learning disabilities. It may become a concern not only for the individual but for the family as well.   Fortunately there are still some available steps in order to combat the possible dilemmas learning disabilities might bring.   Ã‚  Ã‚  Ã‚   On the part of Tony, it seems that he is not really that ready enough to become a part of the larger scope of education structure. He used to have a separated domain of learning which highlighted his interests to accommodate knowledge. The one-on-one teaching method provided by Ms. Brumbley became the most comfortable realm for Tony to achieve success. However, in order to develop more, he needs to take a few more steps of the education ladder. In middle school and beyond, school works are more complex and require more diligence in following directions. Add to that the extremely dynamic social nature of the class where students will tend to stabilize their roles and projections towards other members of the society. Because of such factors, Tony may have a hard time adjusting to the situation.   Ã‚  Ã‚  Ã‚   In order to accommodate Tony to perform his ultimate best, what can be done is to at least set some modifications in the classroom. First is to introduce the basic foundations of new lessons for discussion. For example, a lesson in Math can first take a course of simple arithmetic to fraction computations. This may seem too easy relative for the whole class but exampling to them the importance of the strong math foundation will not impose an obvious aspect that the procedure is intended for Tony to refresh what he has previously learned. It is also possible to provide Tony a separate customized textbook and assignments so that he can gradually adjust to the lessons involved in middle school education. This approach is not intended for a long term basis so that he can actually progress to entertain newer and more complex lessons in middle school subjects. Lastly, as a concerned teacher, he will be provided with at least an hour of academic assistance everyday after class. A consultation form of conversation is best for him so that he could provide any feedback about the class procedures.   Ã‚  Ã‚  Ã‚   In order to support the standing of Tony in middle school through high school, coordinating with his other teachers would be the best practice to do. This will help the whole learning sector to have a single approach in fulfilling the special needs of Tony. Even if after he has completed the year level in a particular class, a complete coordination between his previous teachers and the ones who will be handling him should be initiated.   Ã‚  Ã‚  Ã‚   Basing on some studies and personal observations, individuals like Tony do not simply experience learning problems. The nearest dilemma apart from education concerns is the social interaction aspect of the person. Primarily, if one is not able to acquire the supposedly pace of learning rates in education, then most probably there will be a certain problem within his core interactive capabilities. Of course, it was noted that he exemplifies a certain degree of fondness in dealing with people in a comical way but deep inside, Tony might also have some concerns in having an interaction with people in a serious manner. If he will realize his disadvantages over the people he will constantly interact with, he might experience a sense of inferiority or discrimination. Compassionate encouragement and kindness can minimize the inferiority factor this dilemma might induce (Kentucky Education Cabinet).   Ã‚  Ã‚  Ã‚   Helping the students to explore their capabilities is one way to nurture their personalities. But for individuals who have a relative disadvantage in learning, utmost assistance and care is needed beyond teaching. References Kentucky Education Cabinet. N.D. Learning Disabilities.

Language As A Form Of Communication Essay - 1223 Words

There are many species of life that are more than able to communicate, but humans have a unique form of communication. We are the only species capable of using language as a form of communication. Think about the first people and how difficult it would have been for them to communicate without language. From never having a single word to over hundreds of thousands of words in modern times, all the words that were created in order for people to communicate are a part of a complex system. It is a difficult concept to understand because we ve been using language for most of our lives and all of these words have been in place for thousands of years. Language is something that is constantly changing, it s not an every day change, but it is gradually evolving. For the most part, language is passed down through generations so parents and children are able to communicate with one another. Changes in language have occurred throughout centuries over a short period of time and have evolved thro ugh different degrees of English such as old English, middle English, and modern English. However, old English wasn t the first form of English created, but it s the foundation of our modern day English.
