Causes And Effect Of Oxygen Aids - 1419 Words

Oxygen aids in carrying out several cellular processes of energy transformation for life. In many processes, oxygen is consumed when nutrients, such as protein, carbohydrates, or fats are oxidized, and carbon dioxide is produced as the gaseous waste. Respiration is the process by which oxygen is taken from the environment, delivered to the cells, utilized by those cells, and where carbon dioxide is is produced and delivered to the lungs to be excreted. There are three different categories of respiration; external respiration, gas transport, and internal respiration. External respiration is defined as how a person gets oxygen from the environment and excretes carbon dioxide. Gas transport is the process by which oxygen is distributed and carbon dioxide is removed from cells. Lastly, internal respiration consists of the chemical reactions of cellular metabolism where oxygen is consumed and carbon dioxide is produced. The respiratory system in humans is broken up into an upper and lower division. The upper division consists of the nasal and oral cavities, the throat (pharynx), and the voice box (larynx). The lower division is the system of airways that get progressively smaller that resemble an inverted tree with the wind pipe (trachea), the right and left bronchus, the lobar bronchi, segmental bronchi, subsegmental bronchi, terminal bronchioles, respiratory bronchioles, alveolar ducts, alveolar sacs, and individual alveoli.

Dodge vs Chevy free essay sample

You’re going to the dealership to buy a new diesel truck but you don’t know what brand to get. You’ve been thinking about it, doing a little research and you’ve come to a â€Å"brick wall†. You can’t decide whether to get the Dodge 2500 Cummins or the Chevrolet 2500 Duramax. Well my advice would be to get them both, because they are both GREAT trucks. Each of them is going to last you a long time and give you close to no problems. But†¦Ã¢â‚¬ ¦. Since you may not be able to afford both or have any use for both vehicles, you need to pick one. This paper will hopefully help make up your mind. The Dodge 2500 diesel is the fastest selling truck on the market, mainly because of its Cummins B-series engine. The Cummins B-series engine was introduced to Dodge in 1989. It marked the first time a genuine medium-duty diesel engine had been used in a light-duty truck as the 2500 Ram. We will write a custom essay sample on Dodge vs Chevy or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Sure, other pickups had diesels, but none of them had an engine with a gross vehicle weight rating anywhere near the Cummins B-series 66,000 pound limit. Although it has a great engine, the body is known to be made cheaper than Ford or Chevy. A lot of people have problems with the dash cracking down the middle, paint fading and chipping easier, and when getting in wrecks, the frame breaking when it should have more of a springy characteristic. Also Dodge uses cheap axils, which are the heavy iron bars going from the frame to the wheels. Because Dodge uses cheap axils, the front-wheel alignment gets unaligned easier and can cause, what some people call â€Å"the Death Wobble†. The Death wobble is when you are driving at speeds above 60 miles an hour and all of a sudden the alignment goes out of line and both front wheels start shaking back and forth sometimes causing you to lose control of the vehicle. Although its flaws may sound bad, the Cummins engine over weighs the cons by a long shot. It has more towing power, horse power, its built tougher, and i s known to outlast the vehicle itself. 200,000 miles on a vehicle may sound like a lot but it’s nothing when it comes to a Cummins if used properly. The Chevrolet 2500 diesel also has a good engine but a lot of people don’t like them due to the fact that they are made by Isuzu in Japan so getting parts for them is a bit expensive, also there are not a whole lot of people/mechanics that know how to work on the Duramx engine so finding someone who can work on it is a little bit difficult. Another con about the Duramax engine is that, at around 200,000 miles, they are known to start having problems like injector failure, mass air flow sensors going out, etc, unlike the Cummins engine that can go over 300,000 miles without having any problems. Although the Chevrolet may not have the best Engine, many people would say that is has the BEST transmission. In case you don’t know what the job of the transmission is, they are a cone-shaped part about the size of three tires placed side by side that are connected from the engine to the drive shaft. The engine spins the drive shaft while the transmission switches gears when to engines gets revved up to keep the engine from overheating. Transmissions are not something you would want to be going bad very often. It is very expensive when it comes to getting them replaced. Transmissions are not easily fixed. When something goes wrong, Most of the time the only option is to get a brand new one. Transmissions, for a diesel truck, can cost you anywhere between 2,000 dollars to 8,000 dollars. Chevrolet uses the Allison-Chalmers transmission. Every part inside of this transmission is made to top quality. Many trucks need a new transmission after about 200,000 miles but tests have shown that the Allison-Chalmers transmission can go 300,000 miles, even when hauling heavy loads on a normal basis. Another pro for the Chevrolet is the interior and paint. Chevrolet puts a little more money into the materials used to build their unlike Dodge, for the most part at least. They use better paint that doesn’t fade or chip as easily as dodge and they use thicker and heavier iron for their axils to avoid the constant need for re-alignment. But, like Dodge, the interior is not always considered â€Å"the best†. They have had problems with paint peeling off dashes and door panels and some people say that the material used on the seats are un-modern.

Stomata Lab Report free essay sample

During those high-carbon-dioxide times, plants with fewer stomata will have an advantage and will be common. On the other hand, when carbon dioxide levels are low, plants need many stomata in order to scrape together enough carbon dioxide to survive. During low-carbon-dioxide times, plants with more stomata will have an advantage and will be common. (Understanding Evolution) Therefore, the question to be tested will be if you count the number of stomata of the same species of leaf at different stages of life will the number of stomata be different? My hypothesis is if we count the number of leaf stomata at three different stages of life then the number of stomata will be less as the leaf gets older because the leaf is dying. (Understanding Evolution) Procedure Approximately three leaves of the where gathered to use in this experiment. Each leaf was at a different stage of life: alive, dying, and dead. We will write a custom essay sample on Stomata Lab Report or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page A thin cast of a tiny part of the surface of the underside of each leaf was created using NYC clear nail polish. The imprint of each leaf’s underside was viewed one at a time under a light microscope using the cast, which was carefully removed from each leaf with a piece of packing tape. The stomata were completely visible and were able to be counted under the lowest view setting of 100x. The stomata of each leaf were observed and counted four times. When viewing the stomata in each leaf for detail, the setting of 400x was used. This made the view of the stomata large enough to tell whether they were open or not. The number and description of the stomata of each leaf was recorded. Results Life stage of Leaf| Number of Stomata| Average| Coloration of Leaf| Alive| Trial One: 36s| Trial Two: 34s| 34. 5| | | Trial Three: 34s| Trial Four: 34s| | | Dying| Trial One: 34s| Trial Two: 31s| 31. 75| | | Trial Three: 30s| Trial Four: 32s| | | Dead| Trial One: 27s| Trial Two: 32s| 29. 25| | | Trial Three: 29s| Trial Four: 29s| | | s=Stomata Graph- Number of stomata counted on each stage of life for the leaf X=Trials Y=Number of stomata Results (continued) The number of stomata on each leaf averaged between 29. 25 and 34. 5 stomata in one tiny area observed on each leaf. The leaf that was alive had an average of 34. 5 stomata counted in the one specific area observed, the dying leaf had an average of 31. 75 stomata in the area observed and the dead leaf had an average of 29. 25 stomata in the area observed. These averages were results of four different trials in which the stomata were counted and observed in the specified area of each plant, every trial having a new person count the stomata. The stomata of the dead leaf were closed; the stomata of the leaf that was alive were open. The stomata of the leaf that was dying varied. In some places, the stomata were opened, in others, they were closed. The stomata that were open were bunched in separate areas of the observed section of the leaf, as were the stomata that were closed. Neither of the different stomata were mixed between each other in the dying leaf. All three leaves stomata were scattered around in the observed area and did not have a noticeable pattern to their placing. Conclusion: The data gathered shows that there is, in fact, a difference in the number and the appearance of stomata in three different life stages of an American elm leaf. However, the differences in the number of stomata are slight, calculating to a difference of only 5. 25 stomata between the largest and smallest average. The leaf that was alive had the greatest number of stomata, followed by the dying leaf and then the dead one, which had the least number of stomata. The numbers of stomata seem to descend as the leaf dies. However, this difference is insignificant considering that the stomata that were counted were a part of a very tiny area of the leaf (smaller than a fraction of a centimeter). The difference of stomata in each leaf came out to only 5. 5, which isn’t a large enough difference in the stomata of a small area of the leaf to be determined as significant. Further investigation would have to be performed in order to test this and get more accurate results. The difference that was significant was that of the appearance of the stomata. In the dead leaf, the stomata were closed; in the leaf that was alive, the stomata were open. The stomata of the dying leaf however, varied. Parts of the section viewed under the microscope consisted of opened stomata, others consisted of closed stomata. This might be because the leaf wasn’t completely dead, or parts of the leaf were still alive. When something is dying, the working parts of it do not stop functioning completely, they shut down at various times. This explains why some the stomata are open and some were closed. There was no significant difference in the number of stomata between the three leaves; however there was a dramatic difference in the appearance of the stomata in each leaf. If I were to re-do this lab in the future I would make sure to keep my fingers off of the viewing part of the tape. I think it may have altered our results in the end, like the number of stomata should have been without outliers. Another error that I have discovered was that we used different microscope power for the leaves. We should have used all the same power on each leaf for more accurate results to be sure we were viewing the same amount of area. The data also proves this because for the alive and the dying leaf we used the 100x zoom, but we used 400x zoom for the dead leaf. I’d infer that we did this because the dead leafs stomata were closed which could have made them harder to see. Stomata Lab Report free essay sample A long 350 million years ago, life on land was unsuitable for plants to live on with the little to no supply of oxygen and the harmful ultraviolet rays of the scorching sun. This lead to life beginning in the ocean where scientists have traced back to an ancestral bryophyte (also known as freshwater green algae) that has, over time, developed a key process of making food by using the energy from sunlight to convert carbon dioxide and water into by glucose and oxygen. The plant life history also involves the alternations of generations that allows a plant to undergo meiotic/mitotic phases between the sporophyte(diploid) and gametophyte(haploid) generation. In leaves, gas exchange occurs through little pores called the stomata which are present in the sporophyte generation. These small openings are light sensitive, so they are most commonly located on the bottom of leaves to prevent dehydration. The stomata usually open in the morning, and close in the night in C3 and C4 plants. We will write a custom essay sample on Stomata Lab Report or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Although, many plants species are different when you compare their stomata orientation. One of the two major groups of flowering plants(angiosperms) are monocots, which include palms. These trees have adapted to harsh, dry environments. The deep roots of a palm tree allow it to reach far below the soil and obtain the necessary water and minerals stored at the bottom, and to help it grow. Its giant sized leaves allows for maximum sunlight exposure and its waxy surface cuticle of its leaves prevent the large loss of water from leaf due to transpiration. For the lab, I observed six leaves collected from six different plants growing sporadically around the school campus. Using clear tape, sticking it to the bottom of each leaf, applying pressure, and carefully peeling the tape off for an imprint of the leaf. I stuck the tape onto a glass slide and placed it under the microscope and observed the cells. Adjusting the magnification down 1000x, it is noticeable that the stomata were open since it was early morning to collect any moisture, sunlight, and oxygen in the air. Thus, narrowing down the plants to be either C3 or C4 plants since CAM plants only open their stomata at night. Plant species 1 had mesophyll cells surrounding the stoma were which were formed in parallel layers, similar to the visual on page 128, leading to conclude that it was C3. Plant species 2 had mesophyll cells that were again, arranged in parallel layers so another C3 plant. Plant species 3 is also a C3. Plant species number 4 is also the same. Oh, but plant species 5 is differently arranged, the mesophyll cells are more concentric around the bundle sheath cells, therefore, it being a C4 plant. Plant species 6 has the same mesophyll cell pattern as plant species 5 so it is also a C4 plant. When I got a sample of a palm tree leaf imprint, the mesophyll cells are well-formed and arranged in parallel layers just like Plant species 1, 2, and 3 so a palm tree is a C3 plant. In conclusion, most of the leaves were similar but when observed more closely their differences are more obvious. Some plants had more stomata than the other although they were found on the same part of the leaves. This is most likely due to the fact that each plant has a specific amount of nutrients they need to be well nourished in order to survive. When you compare normal leaves to an actual plant like the palm tree that adapted to Floridas hot environment, there was significantly more stomata all around the not-so broad leaves.

Mosquito Control With Birds and Other Natural Predators

Mosquito Control With Birds and Other Natural Predators When the topic of  mosquito control is discussed, thrown into the mix is usually a fervent argument for installing purple martin houses and bat houses. Stores that cater to bird enthusiasts often tout the purple martin houses as the best solution for keeping your yard mosquito free. Bats, which may not be the most beloved of mammals, are defended with the claim that they consume hundreds of mosquitoes per hour. The truth of the matter is that neither purple martins nor bats provide any significant measure of mosquito control. While both eat mosquitoes, the insect makes up a very tiny portion of their diets. Other animals might have an upper hand on mosquito control, particularly in the fish, other insect, and amphibian classes. Mosquito Munchies For bats and birds, mosquitoes are more like a passing snack. Multiple studies of wild bats have consistently shown that mosquitoes consist of less than 1 percent of their diet. In purple martins, the percentage of mosquitoes in their diet is slightly higher- about 3 percent, at most. The reason is simple. The payoff is small. A bird or a bat that feeds on insects must invest considerable energy in flying around and must catch the bugs in mid-air. Birds and bats are usually seeking the biggest caloric bang for their buck. Given the choice between a mosquito morsel, a hardy beetle, or a mouthful of moth, the mosquito hardly makes the top-10 list. An Efficient Mosquito Natural Predator Gambusia affinis, also known as the mosquitofish, is an American fish that is utilized by some mosquito control districts across the country as a very effective predator of mosquito larvae. As far as natural predators go, the mosquitofish is by far the most efficient natural predator of mosquitoes. The mosquitofish is a voracious predator. In certain studies, mosquitofish have been shown to consume up to 167 percent of their body weight in invertebrate prey, including mosquito larvae, per day. Mosquitofish, as well as small predatory fish such as guppies, can be quite useful in the reduction of mosquito larvae given the right conditions. Other Mosquito Consumers The closely related  dragonflies and damselflies  are natural predators of mosquitoes but do not consume enough mosquitoes to cause a significant impact on the wild mosquito population. Dragonflies are often referred to as mosquito hawks for an unsubstantiated claim of being able to kill thousands of mosquitoes. One thing that does make the dragonfly a better predator than most is that, in the aquatic larval stage, one of their food sources is mosquito larvae. Dragonfly larvae can sometimes live up to six years in this stage. During this phase of life, dragonflies do the most damage to mosquito populations. Frogs, toads, and their young tadpoles are often touted as excellent for mosquito control. In reality, while they do consume their fair share, it is not enough to seriously put a dent in vast mosquito populations. When frogs and toads do consume mosquitoes, it is usually after they have transformed from tadpole to adult.

Kuwaits Parliamentary Democracy

Kuwait's Parliamentary Democracy Kuwait The Ruling al-Sabah Family The al-Sabah family has been ruling over the region since 1756, when it emerged as the most powerful clan among the al-Utub tribal grouping. The tribe had migrated from the Saudi heartland to escape famine. Unlike other ruling families on the Arab Peninsula, the al-Sabah family didn’t seize power by force so much as accede to it by consensus, in consultation with other clans and tribes. That non-violent, deliberative characteristic has defined Kuwaiti politics for much of the country’s history. Kuwait gained its independence from Britain in June 1961. The 50-seat Assembly was established by Kuwait’s November 1962 constitution. Next to Lebanon’s parliament, it is the longest-serving all-elected legislative body in the Arab world. Up to 15 legislators may serve as both lawmakers and ministers. The emir appoints cabinet members. Parliament does not confirm them, but it can vote no confidence in ministers and veto government decrees. No Parties There are no officially recognized parties in parliament, which has it benefits and drawbacks. On the beneficial side, alliances can be more fluid than in a rigid party system (as anyone familiar with the strictures of party discipline even in the U.S. Congress can attest). So an Islamist might join forces with a liberal on any given issue quite easily. But lack of parties also means lack of strong coalition-building. The dynamics of a parliament of 50 voices are such that legislation is likelier to stall than move forward. Who Gets to Vote and Who Doesnt Suffrage isn’t anywhere near universal, however. Women were given the right to vote and run for office only in 2005. (In the 2009 parliamentary election, 19 women were among the 280 candidates.) The 40,000 members of Kuwait’s armed forces may not vote. And since a 1966 constitutional amendment, naturalized citizens, who account for a considerable portion of Kuwait’s population, may not vote until they’ve been citizens for 30 years, or ever be appointed or elected to any parliamentary, cabinet or municipal post in the country. The country’s Citizenship Law also gives government wide latitude to strip citizenship from naturalized Kuwaitis (as was the case with thousands of Palestinian Kuwaitis following Kuwait’s liberation in 1991 from Iraq’s invasion. The Palestine Liberation Organization had backed Iraq in the war.) Part-Time Democracy: Dissolving Parliament Al-Sanah rulers have dissolved parliament whenever they thought it challenged them too aggressively or legislated too poorly. Parliament was dissolved in 1976-1981, 1986-1992, 2003, 2006, 2008 and 2009. In the 1970s and 1980s, dissolution was followed by long periods of autocratic rule and strictures on the press. In August 1976, for example, the ruling Sheikh Sabah al-Salem al-Sabah dissolved parliament over a dispute between the prime minister (his son, the crown prince) and the legislature, and ended press freedom, ostensibly because of newspaper attacks on Arab regimes. Crown Prince Jaber al-Ahmed al-Sabah, in a bit of a hissy fit, complained in his exit letter that â€Å"cooperation between the executive and the legislative branches is almost absent,† and that deputies were too quick with â€Å"unjust attacks and denunciations against ministers.† Namely, himself. In reality, parliament was dissolved over tension related to the Lebanese civil war, which involved the PLO and other Palestinian factions, and its effects on the large, restive Palestinian population in Kuwait. Parliament wasn’t reconvened until 1981. In 1986, when Sheik Jaber was himself the emir, he dissolved parliament because of instability trigfgered by the Iran-Iraq war and falling oil prices. Kuwaits security, he said on television, â€Å"has been exposed to a fierce foreign conspiracy which threatened lives and almost destroyed the wealth of the homeland.† There was no evidence of any such â€Å"fierce conspiracy.† There was plenty of evidence of repeated and angry clashes between the emir and parliament. (A plan to bomb Kuwait’s oil pipelines was uncovered two weeks before the dissolution.)

Trusts and Equity Essay Example | Topics and Well Written Essays - 2000 words

Trusts and Equity - Essay Example In both cases, Chambers writes equity assumptions that the owner was not intended to receive the benefit of the property and raises a resulting trust in favour of the provider of that property. In Re Vandervell's Trusts (No. 2), Megarry J. concluded that the resulting trust operated on different principles in each of these two situations. His lordship classified the resulting trust of an apparent gift as 'presumed' and the resulting trust on the failure of an express trust as 'automatic'. The presumed resulting trust was said to be based on the presumed intention of the provider of the property to create it and could be rebutted by evidence to the contrary. The automatic resulting trust arose independently of intention and was indisputable 2. Resulting trusts arise by operation of law settled on by equity. That means trust is dependant on the decisions of equity particularly in conditions where property has been transferred to another and the provider of that property did not intend to benefit the recipient, equity responds by imposing a resulting trust. The distinction between express and resulting trusts is that the former are created by an intention to create a trust, whereas the latter arise because of a lack of intention to benefit the recipient 3. Geldart writes, "Apart from Common Law and Statute Law, the most important department of our legal system is Equity" 4. That means the vitality of equity is apparent in English law system, that's why when the terms 'law' and 'equity' are used in legal sense, it does not concern about equity being an aspect of law and order, all it means is two different kinds of law the Common Law on the one side while the rules of Equity on the other. It is due to the rule that morally and legally binds to the decisions enforced by the courts. These two sets of rules imposed in the terms of 'law' and 'equity', must not be looked upon as two co-ordinate and independent systems. On the contrary, the rules of Equity are only a sort of supplement or appendix to the Common Law; they assume its existence but they add something further. In this way Equity is an addition to the Common Law. Further, the rules of Equity, though they did not contradict the rules of Common Law, in effect and in practice produce a result opposed to that which would have been produced if the Common Law rules had remained alone. A Common Law right was practically, though not theoretically, nullified by the existence of a countervailing equitable right 5. Though since the Judicature Act came into force in 1875 the rules of Common Law and Equity are recognised and administered in the same court, yet they still remain distinct bodies of law, governed largely by different principles. In order to ascertain the rights to which any given set of facts gives rise, we must always ask (i) what is the rule of Common Law (ii) What difference (if any) is made in the working of this rule by the existence of some rule of Equity applying to the case 6 Like the Common Law, the rules of Equity are judicial law, i.e. to find them we must look in the first instances to the decisions of the judges who have administered Equity. But some branches

An experience - Essay Example Despite of my repeated requests, he insisted on driving. I gave up after trying for a very long time. He was driving very fast and did not take care of the speed limits of the road. His rash driving led to us being stopped by the police. They performed the alcohol test and his alcohol level was above the normal limits. We had broken the law and we had to face the consequences. We were locked up in jail. Our parents reached for our help. They paid the fine. It was a very difficult situation for me. I found it very difficult to face my family and I had placed them in a tough position. I felt very ashamed. I learnt an important lesson that rules and regulations are meant to be followed. This is not only for the good of the society but also for not letting down your family. When I saw the concerned faces of my parents, I realized how reckless I had been. I analyzed that from that day onwards I would always follow the correct path and never let my parents down. My personality has been determined by both environmental as well as genetic influence. The occurrences of my life have alerted and shaped my personality but my response to these occurrences is determined by genetic influence. This is owing to the fact that there are many situations in which I see myself reacting in a similar manner as my father does. Thus my personality has been molded by both genetic and environmental

Tyger Anthology Poem Essay Example for Free

Tyger Anthology Poem Essay The poem begins with the speaker asking a fearsome tiger what kind of divine being could have created it: â€Å"What immortal hand or eye/ Could frame they fearful symmetry? † Each subsequent stanza contains further questions, all of which refine this first one. From what part of the cosmos could the tiger’s fiery eyes have come, and who would have dared to handle that fire? What sort of physical presence, and what kind of dark craftsmanship, would have been required to â€Å"twist the sinews† of the tiger’s heart? The speaker wonders how, once that horrible heart â€Å"began to beat,† its creator would have had the courage to continue the job. Comparing the creator to a blacksmith, he ponders about the anvil and the furnace that the project would have required and the smith who could have wielded them. And when the job was done, the speaker wonders, how would the creator have felt? â€Å"Did he smile his work to see? † Could this possibly be the same being who made the lamb? Form The poem is comprised of six quatrains in rhymed couplets. The meter is regular and rhythmic, its hammering beat suggestive of the smithy that is the poem’s central image. The simplicity and neat proportions of the poems form perfectly suit its regular structure, in which a string of questions all contribute to the articulation of a single, central idea. Commentary The opening question enacts what will be the single dramatic gesture of the poem, and each subsequent stanza elaborates on this conception. Blake is building on the conventional idea that nature, like a work of art, must in some way contain a reflection of its creator. The tiger is strikingly beautiful yet also horrific in its capacity for violence. What kind of a God, then, could or would design such a terrifying beast as the tiger? In more general terms, what does the undeniable existence of evil and violence in the world tell us about the nature of God, and what does it mean to live in a world where a being can at once contain both beauty and horror? The tiger initially appears as a strikingly sensuous image. However, as the poem progresses, it takes on a symbolic character, and comes to embody the spiritual and moral problem the poem explores: perfectly beautiful and yet perfectly destructive, Blake’s tiger becomes the symbolic center for an investigation into the presence of evil in the world. Since the tiger’s remarkable nature exists both in physical and moral terms, the speaker’s questions about its origin must also encompass both physical and moral dimensions. The poem’s series of questions repeatedly ask what sort of physical creative capacity the â€Å"fearful symmetry† of the tiger bespeaks; assumedly only a very strong and powerful being could be capable of such a creation. The smithy represents a traditional image of artistic creation; here Blake applies it to the divine creation of the natural world. The â€Å"forging† of the tiger suggests a very physical, laborious, and deliberate kind of making; it emphasizes the awesome physical presence of the tiger and precludes the idea that such a creation could have been in any way accidentally or haphazardly produced. It also continues from the first description of the tiger the imagery of fire with its simultaneous connotations of creation, purification, and destruction. The speaker stands in awe of the tiger as a sheer physical and aesthetic achievement, even as he recoils in horror from the moral implications of such a creation; for the poem addresses not only the question of who could make such a creature as the tiger, but who would perform this act. This is a question of creative responsibility and of will, and the poet carefully includes this moral question with the consideration of physical power. Note, in the third stanza, the parallelism of â€Å"shoulder† and â€Å"art,† as well as the fact that it is not just the body but also the â€Å"heart† of the tiger that is being forged. The repeated use of word the â€Å"dare† to replace the â€Å"could† of the first stanza introduces a dimension of aspiration and willfulness into the sheer might of the creative act. The reference to the lamb in the penultimate stanza reminds the reader that a tiger and a lamb have been created by the same God, and raises questions about the implications of this. It also invites a contrast between the perspectives of â€Å"experience† and â€Å"innocence† represented here and in the oem â€Å"The Lamb. † â€Å"The Tyger† consists entirely of unanswered questions, and the poet leaves us to awe at the complexity of creation, the sheer magnitude of God’s power, and the inscrutability of divine will. The perspective of experience in this poem involves a sophisticated acknowledgment of what is unexplainable in the universe, presenting evil as the prime example of something that cannot be denied, but will not withstand facile explanation, either. The open awe of â€Å"The Tyger† contrasts with the easy confidence, in â€Å"The Lamb,† of a child’s innocent faith in a benevolent universe.

Oversea Greed Essay -- Dutch Republic, The Netherlands

The Netherlands have been a long time tolerant and rich land. The country opened the Bank of Amsterdam and ran a major trade business incomparable to any other. Although small, the territory bore a perfect harbor for ships of the time. Up until the late 17th century the Dutch Republic had a successful nation, unified under a booming economy. When England and other alliances shifted, the Dutch Republic would experience immense turmoil. England’s reasoning behind allying with the Spanish was solely for personal economic gain and power, by destroying the Dutch unity and economy it left room for England to become the most powerful commerce. The Dutch economy was devastated by the military force of foreign countries. England wiped out over 2,000 Dutch ships within twenty years (Document 3). Having a border across a sea from the Dutch Republic made it easier for the English to demolish the Dutch’s naval fleet than it was for France who was obstructed by the Spanish Netherlands. In fact, the routes the Dutch took for trade to Africa and the East Indies went directly past England, many naval battles were held in this straight (Document 1). The only relatively safe path from England the Dutch could take for a trade route was to the Baltic Sea, but even this route’s trade decreased by approximately 45% over the span of 50 years (Document 2). With a lack of trade the Dutch fell into financial debt rapidly, in just twenty years the Dutch Republic was in almost 150,000,000 guilders of debt (Document 12). None of the provinces could handle this debt except Holland which included Amsterdam, the most successful cente r of trade in all of Europe. However, not even Holland’s wealth could save the Dutch. With the constant financial burdens and ba... ...e Dutch Republic’s despair, so did some of Asia, such as the Portuguese, Chinese, and Muslims (Document 13). The Dutch Republic feared the â€Å"other kings [who] seem more and more to scheme how to ruin what remains of the trade†¦ and to take over part of it for themselves† (Document 7). Not only did England increase her own power by destroying the Dutch Republic, the nation had such a powerful business of trade other countries took the Dutch wealth for themselves. England had no intention to help France; they only wanted more money and power for themselves. This decision resulted in more power for other countries. Although the Dutch suffered greatly, lost national unity and security, and their economy crashed, the balance of power was checked. Ultimately the Dutch power had to end eventually for the balance of power to remain equal amongst European and Asian nations.

Among Incarcerated Juvenile Offenders In Mississippi. Child Psychiatry & Human Development. 35 (1). 55-74. Review of Article This article examined how 14-20% of Juveniles that are incarcerated at Youth Detention facilities suffers some type of diagnosis for a mental disorder and 9-13% can be classified as having a serious emotional disturbance.This rate is very high and shows that the majority of children involved in the Juvenile delinquent system uffers some type of mental illness. This article examine a study conducte dover a 6 month period in 2000 for youth from ages of 12-18. They were found in nine long term youth detention facilities and two long term training schools. The Juveniles had a range of offenses that included aggravated assault, manslaughter, truancy, robbery, trespassing, running away. DUI, and drug offenses. Goal of Study There were actually three goals for this study.The primary goal of the study was to determine the poing prevalence of mental Illness, substance a buse and co-occurring ental health and substance abuse disorders of Juveniles held in Mississippi detention centers and training schools. The secondary goal was to determine the types and severity of problems by gender. The third goal was to examine the geographic differences and similarities in mental health and substance abuse disorders among Incarcerated youth In Misslsslppl compared to other states.Methodology (subjects, number of subjects, research design, Independent and Dependent Variables) The subjects that participated in the study were youth, both male and females between the ages of 12-18 years old. The number of subjects that participated in the study was 482. The youth were incarcerated in long-term juvenile correctional facilities called training schools and nine Juvenile detention centers during a 6 month period in 2000. The youth were approached in groups and Individually. There were 64. 3% (292) males, 65. 4% (297) blacks, 31 . 7% (144) whites and 2. 9% other racial /ethnic groups.The average age for the participants was 15. 3 years. The way that data was research was different at the detention centers and training schools. At the detention centers, Master's level mental health counselors visited ach facility on a weekly basis, approached newly detained adolescnts, and collected measures from consenting youths on an individual basis. The Adolescent Psychopathology Scale (APS), a standardized diagnostic questionnaire, and the Juvenile Detention Interview were collected. The counselors answered 16 mental stattus indicators based on their observation of the adolescent.Interviewers then noted their clinical Impressions. In the training schools, groups of 20-25 Juveniles 1 OF3 the test aftering explaining the purpose of the study. Adolescents that needed ssistance with reading were helped individually. The Juvenile Detention Interview and clinical observations were not conducted at the training due to time constraints. The APS is a 346 item self rep ort measure of adolescent psychopathology that directly evaluates teh severity of symptoms associatd with specific Diagnostice and Statistical Manual of Mental Disorders, Axis I Clinical disorders and Axis II Personality disorders.The APS assesses behaviors that interfere with successful psychosocial adaptation and person competence. The APS has a third grade reading level and is esigned for administration to youth 12-19 years of age either individually or in groups. The APS is composed of 20 Clinical disorders, 5 Personality disorders, 1 1 Psychosocial Problem Content, and 4 Response Style Indicator scales. The findings from this study found that Juvenile offenders have high rates of mental and substance abuse disorders.The most common disorders were ADHD, Conduct Disorder and Oppositional Defiant Disorder. Over half of the offenders in this study met criteria for conduct disorder and 35. 2% for disruptive disorder. The Juvenile Detention Interview is a 30-45 minute face to face se mi-structured nterview that records psychosocial history and includes alcohol and other drug use, mental health problems, and a number of risk factors associated with dlinquency involvement and criminal recidivism.Master's level clinicians collected information on reason for the youth to be admitted to Juvenile detention, youth education/ employment history, home environment, social environment to include gang membership, alcohol/drug use, family history, menal and medical treatment history. The interview also included 16 mental status questions that were completed by the nterviewer b ased on observation of the Juvenile during the interview process. The Juvenile Detention Interview was developed as a mental health and substance abue screening and triage form specifically for use in Juvenile detention centers.There are many advantages of this interview process; it does not require special training to administer, could be administered in the time allotted, and provides a basis for ini tial clinical impressions and services needs. Findings It was found that 17-22% youth had mood disorders, 10-20% had depressive disorders and only about 7% had some type of anxiety disorder. Females were more likely to score higher for Major Depression than males and were more likely to meet criteria for PTSD. Males rated higher for Conduct Disorder.The implications of this study found that many Juveniles mental health needs are going unmet and that mentally ill Black youth are more likely to be placed in Youth Detention facilities and mentally ill White youth are more likely to be placed in psychiatric hospitals. This study has shown that mental health screening are needed to help identify which juveniles are in need of mental health services so that they can get the services eeded to hopefully prevent them from coming back to detention facilities and committing more crimes, routine follow-up is also necessary.The findings of the study were used to assist administration of Juvenile Justice and mental health services for Juvenile offenders. RESPONSE In my opinion in this article the mental health needs of the youth were going unmet because the state instead of focusing the time that was actually needed and using licensed professions they wanted to use shortcuts for time and did not use certain standardized instruments because of time constraints and because mental health linicians did not have to be licensed they were of adequate use for the facilities which were cheaper to use versus the expense of a licensed counselor.I am pretty sure that many Juveniles are Just thrown into detention centers because it is thought that incarceration is therapy when actually it is not; it is actually a hinderance to those who really need help, but the state does minimum for those who are incarcerated and that is a known fact. There is a lack of medical attention and treatment if not only Juvenile facilities, but Jails and prisons for adults as well.

Causes and Events Leading up to the Revolutionary War essays

Causes and Events Leading up to the Revolutionary War essays For the past two-hundred and twenty-five years, the United States of America has been its own empire. However, prior to this time, this country was the equivalent of young child, trying to find its own identity. Great Britain was the mother country for the colonies that had settled onto North American soil during the 1600s. For a time, Great Britain guided, supported, and ruled this new world. As the colonies settled into the Eighteenth century, they entered the realm of adolescence, wanting more freedom, less rule, and more of a voice in what would ultimately be their own destiny. For over 100 years, the United States willingly accepted rule from Parliament. Yet, as Englands situation at home worsened during the mid-eighteenth century, they looked over to the new world to help dig them out of the financial trench they were in. Between the years 1763 and 1775, Great Britain placed a number of acts, taxes, and bullying schemes upon the colonies, in hopes of easing their own mon etary woes. Consequently, these actions which were being pounded upon the colonies proved to be more than they could stand. Finally in 1775, the revolutionary minds of the colonies banded together to fight for their freedom. What I plan to discuss in the following pages is what the British government did to bring the thirteen colonies of the United States to a state of revolt. At the conclusion of the Seven Years War, England had taken a financial beating. Though they were still the most powerful and prosperous nation in the world, England had doubled their national debt. Furthermore, they now had to administer the huge territory consisting of Canada and the eastern Mississippi Valley. This would also prove to be a financial burden. The British needed a solution and they thought to have found it on the opposite side of the Atlantic. The American colonies were regarded as great enterprises to be directed by those who would profit ...

Argument about physically disabled people. We choose a Essay

Argument about physically disabled people. We choose a subject(physically disabled people) on which to alter people's thinking - Essay Example This greatly affects the quality of life people with disability can lead. The negative attitude stemming from the society leads to denial of opportunities for the physically disabled. Physical disability is not distant from everyone of us. Personally, I underwent a major surgery at 16 on my legs which forever changed my understanding of physical disability. The surgery culminated into a rare condition called Miserable Malalignment. Eventually, matters became so complicated for me that the doctors tried to perform a correction by aligning my legs through sawing both of my legs' bones in half, twisting them to the right place and eventually using screws to keep them in place. This condition prevented me from going on with normal life and every aspect of my life was interrupted including my studies. I had become a physically disabled person. Coping with the situation was hard because I had always believed that physical disability was a condition one was born with. Therefore for me becoming physically disabled at age 16 was something I least expected. Of all facets in life, it is my schooling and social life that was worst affected. In terms of schooling I had to change from school based learning to home based schooling just because the school I had been attending had not put in place facilities for the physically disabled. This negatively affected my performance in school. During this time I came to understand how the society had been unfair to the physically disabled. The fact that my school lacked or did not have elevators or ramps dawned on me. It led me to look around and I found that very few schools had in place facilities for the physically disabled. Although the government has come up with reforms specifically those aimed at integrating special education to regular schools this has not been widespread as many schools, churches, hospitals, cinema theatres, shopping malls as well as other public places lack facilities for the physically disabled. My social life was equally affected considering the fact that prior to my surgery I had made friends. This enabled me to understand how society views people with social disability specifically how the society lacks important information on physical disability. The fact that friends deserted me was a clear indication that the society has formed very baseless attitudes towards people with disability. The mere sight of a physically disabled person in a wheelchair is enough to cause people to run away from those they are supposed to offer care to. I realized that there are very many stereotypes which have been formed by the society about physical disability. The society does not understand th at disability is not inability. Therefore it is not rare to hear cases of physically disabled people who are qualified being denied opportunities because the stereotype that; disabled people cannot perform like non-disabled people, is very rife in the community. There is even belief in some communities that physical disability is communicable or contagious and therefore if one is physically disabled, friends and foes alike tend to keep a 'safe' distance. The stereotypes formed around physical disability go in as far as making some parents or caregivers to fail to take physically disabled children to school because they hold the belief that physical

The Challenge of Ethical Behavior in Organizations Essay

The Challenge of Ethical Behavior in Organizations - Essay Example Their main concern is aggrandizement of wealth and the means employed to secure the goal are of no consequence to them. They encourage their senior staff to adopt unethical procedures and soon it becomes the policy of the organization and standard culture of the industry. Ethical diameters are linked to the behavior of the top management and the middle level management and the employees follow the guidelines as per the directions of the masters. To contain the unethical behavior of the employees the management needs to go to the root cause of the problem. A fair system of compensation that will benefit all the employees must be in place as otherwise some employees may pursue their own objectives rejecting the company’s interest altogether. They may use the system to benefit to themselves. The management should always remember that the employees can build an organization as well as they can break it. If the goodwill of the company is lost, in the present highly competitive busi ness environment, it is difficult to recoup it. When the ethical base is strong, the employees will be responsive to the directions of the management. 3. Organizational culture implies dual responsibilities. On the one side are the employees of the organization and on the other side it reflects on those who deal with the organization. Such a culture relates of the entire gamut of activities of the organization. When it is sound the consequential benefits are the enhanced image, public good will and the increased ability to attract talents to be part of the organization. For the employees to be basically sound and industrious basic conditions need to be created first and that is possible by adopting the best ethical practices. 4. Ronald R. Sims tenders two important suggestions for creating and maintaining ethical- oriented culture. That the top managers need to set the standards as it makes the big difference and the lower-level employees follow

Short listening and assignment Essay Example | Topics and Well Written Essays - 250 words

Short listening and assignment - Essay Example The instrumental roles of the drums are to provide brushes on the drums. Drums are beating out a categorical beat periodically as the performance ends (Ventnor43 2012). ii. Melody statements-Melody assertions in the performance have a head arrangement. The head arrangement originates from the lateral thinking around the 12-bar blue sample that encourages the same. In the 2nd chorus, Basie controls this chorus line with a head arrangement that commences with a two-chorus icebreaker (Ventnor43 2012). 4th Chorus: George Hunt comes into his solo on a trombone and the timbral distinction changes from the 3rd chorus so that the brass is soloing forthright and the reeds go together with the background (Ventnor43 2012). The name of the solo to be analyzed is the third chorus performance. This solo engages Herschel Evans coming into his solo on a saxophone escorted by riffs from the brass division. The solo was successful because it was such a popular tune and so simply accepted (Ventnor43 2012). My emotional response is that the solo was normal for big band swingers. The solo was normal between the soloing reed tone and the brass supplement. I liked the timbres because they were distinct and utilized to start out one chorus from the next. Even though Basie is not the only black artist to have endured pain this way, One O’clock Jump† pulls it out the best (Ventnor43

Ancient Chinese Inventions

Ancient Chinese Inventions Ancient Chinese Inventions Early Chinese civilization invented numerous basic and vital necessities that are presently used around the world. Some of the most valuable ancient Chinese inventions include but are not limited to the following: silk, printing, paper, mathematics, Seismograph, the compass, gunpowder, bamboo and medicine (About.com, 2012). It is wildly accepted that the four greatest inventions or contributions to the world were: the compass, the discovery of gun powder, papermaking and printing. One of the Chinese culture’s first inventions was paper. During the 2nd century the earliest form of paper was made from hemp fibers. Even before the end of the ancient times, the Chinese had already acquired a level of expertise with papermaking. During the Qin (221-206 BC) and Western Han (206 BC -220 AD) dynasties, the art of making floss (rough silk) from inferior cocoon was greatly utilized. The basic process of making the floss (named Piao Xu) included continuous â€Å"thrashes† and â€Å"stamp crushing† (which involved a mill for crushing). Afterwards, the same procedure was used in papermaking. During ancient times, Chinese people used limewater or plant ash water to separate raw silk from the gum component. This system paved the way for future papermaking, which utilizes degumming vegetable fiber in the papermaking process (ChinaCulture.org, 2012). During the Eastern Han dynasty, approximately 104 AD, a â€Å"eunuch† of the Imperial Court named Cai Lun invented a new type of paper. He took bamboo fibers and the inner bark of a mulberry tree, added water to these and pounded them using a wooden tool. Once pounded thoroughly, he poured the mixture over a flat woven cloth allowing the water to drain out. When the mixture dried, only the fibers remained. Cai Lun then realized that the material he made had a good writing surface and was lightweight. It was also easy to make. Cai Lun also used other materials when making paper. Materials such as remnants or hemp, tree barks, fishnets and linen rags were also used. In 105 AD, Cai Lun went to He Di, the emperor of China at that time and presented his invention. Once the emperor viewed the paper, it was then officially invented (Totallyhistory.com, 2012). Cai Lun paved the way for China to develop literacy more rapidly than the West. Even though paper had been made by Han for ove r 200 years, Cai Lun improved the techniques to make it and the quality. The process of making paper has been simplified by advanced technologies, but the process of making paper remains fairly the same-softened plant fibers, suspended in water, is formed in moulds into thin sheets, pressed, drained, and then dried (Sayre, 2011). Ancient historic records show that the Chinese had many natural remedies which included natural herbs and acupuncture. The foundation of Chinese medicine was thought to have occurred more than 2000 years ago. Much of ancient medical knowledge comes from the Han dynasty (206 BC-220 AD), which produced a guide that is even utilized today. The guide was called â€Å"The Treatise on Diseases Caused by Cold Factors† by Chang Chung Ching. It is regarded as perhaps the best Chinese medical work of the Materia Medica, compiled in the Ming dynasty (1368-1644 AD) by Li Shih Chen. This comprehensive journal paved the way for further advances in the world history of medicine. It includes 1,892 descriptions of different types of medicines and has been translated into several foreign languages. It has also been useful in East Asian and European countries (Thinkquest.org, 1998). Ancient Chinese felt the purpose in making medicine was to create an â€Å"elixir of life†; to make emperors immortal and help them live forever. In their quest to make the elixir, they instead, made numerous medicines and remedies. The Chinese got the idea to develop an elixir from Tao Ch’ien, a poet and philosopher. Tao Ch’ien believed that if the Chinese discovered a method of turning metal into gold, which last forever, then they could at the same time, find the elixir of life. This belief encouraged doctors and pharmacologists to begin searching for a method of making metal into gold. They also tried to learn other ways of becoming immortal, and that led to the discovery of the elixir. After creations made, resulted in the healing of various ailments, there was even more determination to make the elixir. Tsou Yen, a pharmacologist, formed of how he thought diseases were caused. His belief was that there were two spirit-like forces, called the Yin and Yang, w hich flowed throughout the body. He thought diseases were caused when either Yin or Yang were out of balance. This concept is still used today in medicine (About.com, 2012). Gunpowder was the next profound creation by ancient Chinese. Ancient Chinese alchemists spent centuries trying to develop an elixir for immortality and the use of saltpeter (potassium nitrate) was an ingredient in many of the failed elixirs. Around 850 AD, during the Tang Dynasty, an alchemist mixed â€Å"75 parts saltpeter with 15 parts charcoal and 10 parts sulfur†. The mixture failed as an elixir but was explosive when it was exposed to an open flame. The impact was severe enough to cause â€Å"smoke and flames†, which resulted in the hands and face of the alchemist being burnt. The Chinese proceeded to use the gunpowder for fireworks (About.com, 2012). It was also used by the Song dynasty’ (904 AD) armed forces against their enemy, the Mongols (About.com, 2012). Their weapons included â€Å"flying fire†, an arrow with a burning tube of gunpowder attached to the shaft. Flying fire arrows were like miniature rockets, propelled at the enemy, producing fear. Other Song dynasty uses of gunpowder included hand grenades, poisonous gas shells, flame throwers and land mines. Initially, artillery pieces were rocket tubes made from hollow bamboo shoots, but were redesigned to cast metal. McGill University professor Robin Yates, notes the world’s first image of a cannon comes from Song China, in an illustration from around 1127 AD (About.com 2012). Last but not least, and probably the most important, is the creation of print. During the Tang dynasty (618-906 AD) printing was inventing. It began as blocks of wood used to print fabric but was then used to copy Buddhist holy books. Later, scrolls and books were printed, initially via wood-block printing and by the 11th century, by portable printing. During the Song dynasty (960-1279 AD) affordable, printed books became widely available. As late as the Tang dynasty, block printing was limited in its use as the method for production of books. It was not until the time of the late Tang dynasty (923-936 AD), when the government sponsored the reproduction of the â€Å"Five Classics† via block printing, that all important books were block printed (Ross, 1982). The printing method advanced further during the Ch’ing-li period (1041-1048), with the invention of the movable type. However, during that time, the movable type faced constraints because the Chinese character ideograms were too strict. Consequently, thousands of characters were too difficult to mold. As technology advanced, the movable printing press, invented by Johannes Gutenberg, allowed printing to move to other cultures. Gutenberg is credited with transforming society with mass printing, thus enabling the dispersal of information to many. â€Å"This print invention is regarded by many as the invention of the millennium (Ross Jr., 1982). And I personally feel as though it is the most important invention that I as well as the world could not live without. Through many centuries, ancient Chinese inventions have had profound effects on human culture†¦ some more useful than others. References About.com (Part of The New York Times Company). (2012).

Character and Setting Analysis of Bride Comes to Yellow Sky Essay

Character and Setting Analysis of Bride Comes to Yellow Sky Setting and characters go hand in hand in The Bride Comes to Yellow Sky. With Each new setting there is at least one new character development. A new setting in each part of the story makes for diverse settings and characters. From a train leaving San Antonio to around the corner in a small town in Texas, a drunken gunslinger to negro waiters, this story has it all. This story begins on a train specifically in a parlor car. This is where Jack Potter and his new bride are first introduced though his name is not yet given and hers never is. Crane chooses to tell about Potter in part one of the story so as not to give too much information at once, we do suspect? however that he will develop into the protagonist. The train is coming from San Antonio, where Potter and his bride were just married, and going to Yellow Sky, Texas. Eventually the setting changes as the couple moves to the dining car. Two rows of ?negro waiters? stand ready to assist and so the Potter?s are seated and presumably fed. The waiters in the dining ...

Letter to Shakespeare Essay

Having studied the play, â€Å"Macbeth†, imagine that letters can be sent to the past and that Shakespeare is living in retirement at Newplace, Stratford-Upon-Avon, Warwickshire, England. You decide to write him a letter telling him about the success of his play, â€Å"Macbeth†, in the 21st century and this play is still being read and performed and filmed. Dear William Shakespeare, I am writing to you from the 21st century as we have developed a new way which allows us to write letters to people in the past. I am very glad to tell you that your play, â€Å"Macbeth†, has become very successful. People admire what you have done in Macbeth. Macbeth is very relevant today for example we have women like Lady Macbeth, as well as men plotting evil crimes. Macbeth has something we call timeless themes, timeless themes are things that are written about in the past but still occur in every day life and are relevant to people now. The people of the 21st century are very fond of the characters you put into Macbeth. They like how Macbeth changed from a noble character to an evil villain. The thoughts that go through his mind interest them a lot. The way Macbeth’s conscience takes a hold of him and grows to be a hurdle as he progresses through the play. The social and cultural attitudes of people of my time have changed vastly. People in the Elizabethan time respected and feared the monarchy for example in act 5; scene 7, Macbeth’s soldiers were fighting not because they loved him but because they were afraid that he might kill them. The monarchy also had all the power. I am not saying that everyone does not respect the monarchy but the majority of people do not. The people of our time are not scared of the monarchy now either as the people have realised that the parliament have the most power now. The monarchy is more of an iconic figure that shows the heritage of Britain and has a less important role in the running of the country. Macbeth emphasised witchcraft in numerous ways but the thrill for witchcraft has died down in our time. Witchcraft was very popular in your time. Witches were seen as evil creatures e.g. Banquo says â€Å"The earth hath bubbles, as the water has, and these are of them†¦Ã¢â‚¬  This shows that Banquo does not trust the witches and as the general public would think in your time Banquo classes the witches as rare and evil. Most people now do not believe in witchcraft but are still intrested when they read about it in your play. I was intrigued by the witches in the first scene when they started chanting because it grabbed my attention and got the play to a great start. People are now going to the cinema more than they go to the theatre as the theatre is seen as old fashioned now. However you will be pleased to know that you movie is being broadcasted on TV and cinema too. As I said before, your play uses something we call timeless themes. People of our time still enjoy reading all your plays. They love the humour of Midsummer Night’s Dream and cannot get enough of the romance of Romeo and Juliet. They enjoy these plays as they have incidents which are still relevant to us know. Personally I think the reason Macbeth is so popular is because of its successful structure. The structure is simple but very effective. I have realised that you introduced the witches in the first scene to grab the readers’ attention and to keep them interested through the whole play. The witches at the end of the scene say, â€Å"Fare is foul and foul is fare, hover through the fog and the filthy air†¦Ã¢â‚¬  I think you put this bit in to confuse the people watching and make them think about what has been said and keeps the audience’s attention through the rest of the play. Act 3 Scene 5 is the next big scene where the witches get a lot to say. In that scene you have made the witches talk about Macbeth once more. This shows that the witches are intrigued by Macbeth, â€Å"†¦to trade and traffic with Macbeth†¦Ã¢â‚¬  The witches have mixed feelings about what they have done to Macbeth. The witches conversation about Macbeth makes the audience think about what the witches plan on doing next. I was interested and got into the play most when you created dramatic irony in the play for example when the audience knew Macbeth was plotting to kill Banquo. However he was being very nice to Banquo and Banquo had no idea he was walking into a trap. â€Å"Here’s our chief guest† Macbeth said as he talked to Banquo and Lady Macbeth, although he was actually plotting to kill him. You also added in soliloquies into the structure, mainly Macbeth’s. The soliloquies focused on a fight between Macbeth’s guilt and Macbeths ambition, â€Å"Our fears in Banquo stick deep, and in his royalty of nature reigns that which could be feared†¦Ã¢â‚¬  In almost all of the cases Macbeth’s ambition came ahead of the guilt he had. You had put in some very strange characters but managed to fit them in magnificently well. People in your time must have been amazed to see a woman (Lady Macbeth) committing a crime. However, in the 21st century we have women committing crimes almost as frequently as men. Lady Macbeth in your time was unique as she was a villain. It fascinated people then and even though women committing crimes is not rare it still fascinates us now. Witches were very popular in your culture, I understand that King James even wrote a book about them called Demonologie! The witches that intrigued people on your time still have an impact on us even thought it is not the main talking point in our culture. The character of Macbeth is really complicated. His character is what we call a tragic hero. Macbeth was introduced as a brave fighter which really caught the eye of the audience, â€Å"Hail, brave friend†¦Ã¢â‚¬  The evil of the witches changed him completely into a criminal. His ambition to be the king was his downfall and that really shocked the audience. Who would have thought that ambition was a bad thing? The ambition came from the witches’ prophecies which portray them as evil once more. The witches talk in rhyming couplets. The language you used was amazing. You had to describe the surroundings using only speech for example â€Å"How goes the night boy†¦Ã¢â‚¬  It worked very well and it shows that you do not need props to describe the surroundings. I have realised that you have used a lot of imagery in your play as well in the form of similes and metaphors, â€Å"like a rat without a tail† It is very effective and adds something new to the plain language in a normal conversation. The Duncan murder scene which you left out was a good decision. I believe that you did not have props to show the murder and also that you thought it would have been disrespectful to the monarchy if you put the scene in. However, people have been making new versions of your play with Duncan’s murder added into it. A man called Roman Polanski made a version of Macbeth with scenes added into it. In Act 2 Scene 1 Polanki puts in different camera angles to portray what certain characters are doing at the time. The castle is full of stair cases and long corridors. When the dagger appears there is strange music going on in the background suggesting Macbeth is going to do the unnatural by killing Duncan. In the same act he also uses a lot of silence to create tension and suspense. He puts a close up on Lady Macbeth to show that she’s trying to keep out of sight from Banquo and Fleance. Polanski uses a great technique to show who is hiding or not. He puts the characters in dark light to show they are not prepared to show their face. Polanski adds extra bits in Scene 1 and Scene 2 of Act 2. He added these bits as it would be easier for the viewer to make sense of the whole play. When Macbeth approaches Duncan’s room, you notice white light coming from it which is to show that he is innocent. As Macbeth gets closer to the room the light begins to flicker showing that Duncan is in trouble. Polanski shows Duncan’s murder in a gruesome manner. Duncan’s death is emphasised by his crown falling to the ground, thus showing that the King is no more. In conclusion as I have mentioned before, your play is very successful. My favourite character is Banquo. I like him as you have portrayed him as an innocent and a noble man. I feel that he is one of the few innocent people all the way through the play because the other characters are changed by evil around them. I loved the moment when Banquo’s ghost came back to haunt Macbeth as it seemed very unnatural. In that moment people at the banquet, including his wife, see Macbeth as cowardly and insane. This was in contrast to the impression people had before when they thought of him as a brave, fearless and noble soldier. Overall the popularity of your play has not died down over the years and your play has been transformed into movies and TV programmes with great success.

Click the Sheet Metal Parameters icon . The Sheet Metal Parameters dialog box is displayed. 1. The second tab concerns the bend extremities. A combo box displays the six possible axial relimitations for the straight bend: These options can also be accessed through the pop-up button: Bend Extremities http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0103. htm (1 of 2) [12/7/2001 5:13:22 PM] Maximum: the bend is calculated between the furthest o pposite edges of the supporting walls. Bend Extremities http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0103. tm (2 of 2) [12/7/2001 5:13:22 PM] Minimum with no relief: the bend corresponds to the common area of the supporting walls along the bend axis. Square relief: a square relief is added to the bend extremity. The L1 and L2 parameters can be modified if need be. Round relief: a round relief is added to the bend extremity. The L1 and L2 parameters can be modified if need be. Linear: the unfolded bend is split by two planes going through the corresponding limit points (obtained by projection of the bend axis onto the edges of the supporting walls). >Tangent: the edges of the bend are tangent to the edges of the supporting walls.Bend Corner Relief This section explains how to change the bend corner relief. Open the CornerRelief01. CAPTPart model from the samples directory. Within the Tools -> Options -> General -> Parameters -> Knowledge tab, check the Load Extended Langu age Libraries option. See Customizing Knowledgeware Applications. Click the Sheet Metal Parameters icon . 1. The Sheet Metal Parameters dialog box is displayed. The third tab concerns the bend corner relief. By default, no corner relief is created when a bend is created. Check the Automatic corner relief creation option to activate this creation every time a bend is created.Three corner relief types are available. Select the icon corresponding to the requested type: : square: the square corner relief is created using the bend limits. Its dimensions are defined by the width of the unfolded bends. : circular: its center is located at the intersection of the bend axes. For that option, a radius is proposed by default. It is equal to the bend radius + the thickness. To change it: Selecting Formula -> Deactivate from the contextual menu of the input field and enter a new value, clicking on the button and entering a new formula. Bend Corner Relief http://arbredsy/FmoCXR8/SheEnglish/sheug. oc/src/sheugbt0104. htm (1 of 3) [12/7/2001 5:13:23 PM] : triangular: the triangular relief is created from the intersection point of the inner bend limits towards the intersection points of the outer bend limits with each wall. The corner relief is not previewed during its creation. The corner relief is taken into account in the unfolded view. For better result, you should select the Maximum Bend Extremities option when creating corner relief. These parameters are applied to each corner relief created or to be created, except to those with that have been redefined, or the locally defined corner relieves.Bend Corner Relief http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0104. htm (2 of 3) [12/7/2001 5:13:23 PM] Defining the Bend Allowance This section explains the calculations related to folding/unfolding operations. Click the Parameters icon . 1. The Sheet Metal Parameters dialog box is displayed. The fourth tab concerns the bend allowance. When a bend is unfolded, the sh eet metal deformation is represented by the bend allowance V, defined by the formula: L = A + B + V where: L is the total unfolded length A and B the dimensioning lengths as defined on the figures below: bend < 90 ° bend > 90 °Bend Allowance http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0102. htm (1 of 3) [12/7/2001 5:13:23 PM] Another way to compute the sheet metal deformation is the neutral fiber definition (K Factor): W = a * (R + k * T) where: W is the flat bend width R the inner bend radius T the sheet metal thickness a the inner bend angle in radians. If b is the opening bend angle in degrees: a = p * (180 – b) / 180 Physically, the neutral fiber represents the limit between the material compressed area inside the bend and the extended area outside the bend. Ideally, it is represented by an arc located inside the thickness and entered on the bend axis. Therefore the K Factor always has a value between 0 and 0. 5. When you define the sheet metal parameters , a literal feature defines the default K Factor, according to the DIN standard: K = (0. 65 + log(R / T) / 2) / 2 This formula can be deactivated or modified using Knowledge Advisor workbench. When a bend is created, the bend K Factor and the bend allowance literals are created. Two cases may then occur: If the Sheet Metal K Factor has an activated formula and uses the default bend radius as input parameter, the same formula is activated on the bend K Factor with the bend radius as input.Else the bend K Factor is a formula equal to the Sheet Metal K Factor. The bend allowance literal is equal to a formula representing the use of the bend K Factor. This formula is fairly complex and it is strongly recommended not to delete it. V = a * (R + k * T) – 2 * (R + T) * tan ( min(p/2,a) / 2) Though it is possible to deactivate the formula to enter a fixed value. Finally, the bend flat width is computed from the bend allowance value. The bend allowance can be locally redefined when cre ating bends from walls, generating bends automatically, Bend Allowance http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0102. tm (2 of 3) [12/7/2001 5:13:23 PM] Creating Walls This section explains and illustrates different methods to create walls. Create walls from an existing Part: click the icon, and select a face of a wall Create a wall from a sketch: use the sketcher to define the profile, and set the material side. Create a wall tangent to another one: select a profile coincident with an existing wall, and select the wall to which it should be tangent Create a wall from an edge: select a wall edge, set the height, limits, angle, then the sketch and material sides Creating walls http://arbredsy/FmoCXR8/SheEnglish/sheug. oc/src/sheugbt0800. htm [12/7/2001 5:13:23 PM] Creating Walls From an Existing Part This task illustrates how to create a Sheet Metal part using an existing Part, that is recognizing the thin part shapes of the Part as created using the Part Design workb ench or from a CATIA Version 4 Solid for example. Open the WallScenario1. CATPart document from the samples directory. The document contains a Part created in the Part Design workbench and it looks like this: 1. Click the Walls Recognition icon 2. Click any face to be the reference wall. The Walls Recognition Definition dialog box is displayed. 3.Choose the Wall creation mode: Part body recognition: the whole solid is processed and walls are created wherever possible Only selected faces: only explicitly selected faces of the solid are processed and the corresponding walls are created. The Reference wall is indicated in the Walls Recognition Definition dialog box for information only (it is grayed out). From an Existing Solid http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0201. htm (1 of 3) [12/7/2001 5:13:23 PM] Select faces as the Compulsory walls. These are faces from which the walls are to be generated when there might be an ambiguity.For example, if the initial part is a box, you will need to select two opposite inner faces and outer faces on the other two sides of the box, in order to avoid overlapping when generating the walls. 4. 5. Set the Internal profiles recognition mode: As cut out wall: generates walls with inner contours (no cutout feature is generated) One cut out by wall: regardless of how many pockets there are on a face of the solid, only one cutout feature is generated per wall One cut out by profile: for each inner contour on the sketch-based solid, a cutout feature is generated None: whether there are pockets on the solid aces, or not, no cutout feature is created in the resulting SheetMetal features. The Generate Bends check button allows the automatic creation of bends as the walls are being created, wherever applicable. 6. Click Apply. The walls are generated from the Part Design geometry. The Walls Recognition. 1 feature is added to the tree view. At the same time, the Sheet Metal parameters are created, deduced from the Part geometry. Select the icon to display the sheet metal parameters: 7. the Thickness is equal to 1mm the Bend radius is twice the thickness value the Bend Extremities field is set to Square relief.From an Existing Solid http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0201. htm (2 of 3) [12/7/2001 5:13:23 PM] You can modify a few of these parameters The Thickness parameter cannot be modified because it is based, like the bend extremities and radius, on the initial solid geometry . However you can modify these parameters (bend radius and bend extremities) to be taken into account for sheet metal features other than the â€Å"recognized† ones. The bend allowance, being used to unfold the part, and the corner relief affect all features, and therefore can be edited even for â€Å"recognized† features. . Click OK in the Sheet Metal Parameters when all parameters have been redefined where needed. The solid is now a Sheet Metal part. All the features are displayed in th e specification tree. Once the solid has been converted to a Sheet Metal part, you can create bends as with any other Sheet Metal part, or modify/add Sheet Metal features to complete the design. Uncheck the Generate Bends button, if you do not wish bends to be created automatically.

The tangent wall is unfolded as a wall linked by a bend to another wall, would be. 8. Creating Walls From An Edge This task shows how to create walls from edges of an existing wall. This function is used to create a box in an easy and quick way from an existing reference wall. At least one wall must already exist. Open the Wall1. CATPart document from the samples directory. Click the Wall on Edge icon and select an edge of an existing wall. 1. The Wall On EdgeDefinition dialog box is displayed together with a preview of the wall. Define the type of wall to be created by specifying the Reference, that is: 2. the Height of the wall: that is the orthogonal projection from the top of the wall on edge to the reference wall. Select the icon to define the height of the wall from the bottom of the reference wall or the icon to define the height of the wall from the top of the reference wall . the Length of the wall: that is the absolute value of the wall on edge without bend. From an Edge http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0802. tm (1 of 6) [12/7/2001 5:13:25 PM] the limits of the wall: LIM1 and LIM2. These texts only indicate on which side a given limit is. They are not precisely on the limit spots. The actual locations of the limits are defined with the icons and an input distance that is taken into account respectively from the inner side of an existing bend, the inner side of an existing wall or the outer side of an existing wall. the angle of the wall: by default it is perpendicular to the plane containing the edge. You may modify it according to your needs. it is updated dynamically on the screen. This preview gives information about: he Sketch Profile: by default, if you pick an edge on the top of the reference wall, the direction of the wall is upwards, if you pick an edge on the bottom of the reference wall the direction of the wall is do wnwards. Preview with top edge selected Preview with bottom edge selected You can invert the sketch's position, and therefore the wall's, using the Reverse Position button. Preview with bottom edge selected and sketch profile inverted From an Edge http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0802. htm (2 of 6) [12/7/2001 5:13:25 PM] the material side: by default the aterial side is proposed so as to keep a continuity with the reference profile. However, you can change it by clicking the red arrow or the Reverse Side button. Check the Clearance option to offset the wall on edge from the selected edge. 3. The entered value is the radius of the bend on this edge. Wall on edge with clearance Wall on edge without clearance Note that the reference wall remains unchanged when changing the bend radius value. It is the Wall on Edge's length that is affected. You can also choose to create the wall with or without a bend by checking the With Bend option. 4.If there is no wall from which a limit can be computed, the reference element is the edge of the reference wall. From an Edge http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0802. htm (3 of 6) [12/7/2001 5:13:25 PM] A wall on edge is defined by the selected edge (reference edge). When the reference edge is modified, by adding any feature that shortens the edge (a bend to an adjacent wall on edge or a cutout for example) the wall on edge based on this reference edge is recomputed. To avoid this you may: create the bend manually on the wall modifying the edge used as the reference to create the other wall eorder the creation of walls to postpone the creation of the modifying feature Both limits are computed with the same reference icon. The bend is not previewed, even if the option With Bend is checked. However it will be created. The selected options are modal and will be proposed to create the next wall. Walls on edge being contextual features, if you break the profiles continuity by inverting the material side of a wall, you may have to manually re-specify all features based upon the modified one, even if they are not directly connected to the modified wall, in order to update the part afterwards.This is the case when creating a wall on edge from another wall on edge, for example: From an Edge http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt0802. htm (4 of 6) [12/7/2001 5:13:25 PM] If you invert the material side of the reference wall on which the first wall on edge has been created, both walls on edge are relocated (as if you were flipping the geometry): If you invert the material side of the first wall on edge (and not the material side of the reference wall), the second wall on edge is relocated. Indeed, its specification being relative to the first wall on edge, when its input data (i. e. he edge selected on the first wall on edge) is modified, the second wall on edge is rebuilt at a new location. 5. Click OK in the Wall On Edge Definition dialog box. A WallOnEd ge. x element is created in the specification tree. A WallOnEdge. x element can be edited: double-click it in the graphic area or in the specification tree to display its creation dialog box and modify the parameters described above, including the edge from which it is created. However, the sketch of a wall on edge cannot be edited directly. Would you need to edit the sketch of a wall on edge, you have to isolate it first. See Isolating Walls.You can cut or copy and paste a wall on edge. If you cut and paste a wall on edge with children elements, these children elements are lost. This may result in update errors. You cannot undo an Isolate action after having modified the wall. Isolating a wall on edge erases all updating data.

Click OK. The walls corresponding to the selected sketch are created according to the specified options, and added to the specification tree. When the extrusion is the first Sheet Metal feature of the Part, the reference wall is the first wall created based on the first segment of the sketch.For option Up to Surface, while the wall end that is limited by the surface has the shape of the surface, its thickness does not fit the surface. It is a â€Å"rectangular† polygon defined by the first edge that comes into contact with the surface. Extruding http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt1100. htm (3 of 4) [12/7/2001 5:13:25 PM] Check Symmetrical thickness to create thickness inside and outside the sketch. Such an extrusion can also be performed on a sketch made of lines and arcs of circle, provided there are no tangency discontinuities between the different elements. However, in this ase, the Up to plane or Up to surface capabilities are not availab le, and you cannot isolate such an extrusion. Extrusion walls can be edited and/or isolated. The sketch may not be closed. Extruding http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt1100. htm (4 of 4) [12/7/2001 5:13:25 PM] Isolating Walls This task explains how to isolate a wall. This is possible in two cases: 1. after having created walls by extrusion (see Extruding) 2. after having created a wall on edge (see Creating Walls from an Edge). You must have defined the Sheet Metal parameters. A model is available in the Extrude2. CATPart from the samples directory.Isolating Extruded Walls Right-click the Extrusion. 1 feature and choose the Extrusion. 1 object -; Isolate contextual menu item. 1. The Extrusion Isolate dialog box is displayed. Select one of the wall of the extrusion to be isolated. 2. The selected wall is highlighted in the geometry. This wall is the reference wall, meaning that it can be modified and the other walls will take the modification into account. On th e other hand if the other walls are modified the reference wall is an anchoring wall, and modifications will be made around it. The Extrusion Isolate dialog box is updated. 3. Click OK in the dialog box.The walls of the extrusion have been isolated, each with its own sketch. Yet coincidence constraints are automatically generated between the isolated walls.

Double-click the sketch of the reference wall (here Sketch. 3) and modify it by increasing its length. 4. Exit the Sketcher using the Exit icon . 5. The Part is updated. You can note that the wall that was adjacent to the pad, now lies on it, as it is the reference wall that was modified.Isolating Walls http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt1701. htm (2 of 4) [12/7/2001 5:13:25 PM] However, had you modified the sketch of t he wall lying on the pad (Sketch. 4), moving it further away from Wall. 2 as shown here to the right, the updated pad would not take the gap between the walls into account. The resulting part looks like this (Wall. 3 has been modified but still coincides with Wall. 2): Isolating Walls http://arbredsy/FmoCXR8/SheEnglish/sheug. doc/src/sheugbt1701. htm (3 of 4) [12/7/2001 5:13:25 PM] You can then edit its sketch if needed. In the present case, the wall on edge had been created with a end. Therefore when isolating this wall from the reference wall, the bend is created as a separate feature that can be edited as well. The angle value between the two walls is displayed for edition. You cannot undo an Isolate action after having modified the wall. Isolating a wall on edge erases all updating data.

Be careful when creating bends with square or round relief. Depending on the geometry configuration, this can lead to removing more matter than you would expect. Indeed, a corner relief being computed on the whole intersection of the elements involved (bends or bend/wall), in the following configuration the matter is removed till the end of the wall.Bend with no relief Bend with square relief In this case, it is best to replace the bend corner relieves with cutouts (identified in red in the figure below) that will act as corner relieves removing matter to the part.
