What this means exactly is that one must give up all desired in the temporary life so that they can focus on faith for the eternal after life. In the Holy Grail, countless examples and tests are depicted for the knights of Arthur s round table to try to loose themselves. Although this was no easy task for them, some managed to see the Grail while others didn t.

He was about to give in to temptation but he then remembered the words of his king and went on his way. While Percivale had this experience, Lancelot had a totally different one where some could say that he lost all his sanity. The difference lay in that Lancelot had a horrible sin to his name while Percivale didn t. Lancelot was told by Arthur that he could make it because even a seedling could bloom on a swamp. What this meant was that no matter how deep Lancelot was in his sin, God would find a way to forgive him. So Lancelot went ahead on his journey but he tried to commit suicide as he went on a boat and out to sea for seven days. On the seventh day, he got a break from the sea- just as God did- and landed at the shores of Carbonek where his son Galahad had been born. All the way to the entrance, lion statues kept appearing as his symbol was the lion. This was to represent that he was about to have some conflict with himself. As he crosses two lions at the entrance, they take away his sword as he subconciously is prepairing himself to enter in his realm of curing himself. As Lancelot entered the castle, he could see nothing as h is soul was at the time empty at the bottom. He heard a voice calling him from above in the direction of whereShow MoreRelatedEssay about The Once and Future King1411 Words Ã |Ã 6 Pages The Once and Future King, or King Arthur, is a legend that is, despite its age, known by all.

According to AccountingTools (n.d.), corporate controllers are responsible Ã¢â¬Å"for the accounting operations of the company,Ã¢â¬ including: the development of recurring financial reports, Ã¢â¬Å"maintenance of Ã¢â¬ ¦ accounting records, and a comprehensive set of controls and budgets designed to mitigate risk, enhance the accuracy of Ã¢â¬ ¦ reported financial results, and ensure that reports results comply with Ã¢â¬ ¦ financial reporting standardsÃ¢â¬ (para. 2). In other words, controllers are the chief accountants in their organizations. Besides their basic daily accounting functions and managing the accounting staff, controllers must maintain internal controls and assume expanding responsibilities in their firms to reflect the changing roles in the controllership position. In a typical midsize or large business, the accounting department will usually have accounting clerks, payroll clerks, staff accountants, senior accountants, an accounting manager, and other accounting positions (e.g., accounts payable clerks, accounts receivable manager, etc.). However, most accounting departments of midsize or large corporations will be led by a controller or someone with similar responsibilities (e.g., finance director, etc.).

So this would lead me o mini panic attacks because would feel overwhelmed with assignments and test all coming at once and not wanting to fail. Lastly, studying was an enormous stress factor because had no study habits nor a study group.

Question: Discuss about theLaw for Sexually Transmitted Disease. Answer: Introduction: Sexually transmitted infections are very common in the young people, and especially those who are sexually active. Such infections endanger the long term health of youth such as it is not possible to cure some STI and some STI damage the reproductive system if it is not treated. Because of these issues it is desirable to provide information related to sexual health problems, and availing the treatments on time is the best solution to reduce and prevent these infections (Dehne Reidner, 2001). This essay states the one sexually transmitted disease which is common in the young people who are sexually active. In this paper, we discuss Chlamydia among young people and lastly paper is concluded with brief conclusion. Sexually Transmitted disease: Sexually transmitted infections are not new, but STI rates in Australia and in other developed nations had been rising in recent years. As per the health data issued by Kirby institute, almost 18,588 cases of STI were detected in the year 2015 and almost 8388 cases in 2006. STI cases were almost doubled in last few years. This is the data of one infection only, and this story is almost similar in other infections also (Advocates for Youth, n.d.) . Various STI are detected in young generation, and the infection of Chlamydia in sexually active youth was 4.8% in Addis Adaba, and it is considered as the most common infection in the sexually active students (Taffa Sundby, 2002). Chlamydia: It must be noted that, Chlamydia is considered as treatable disease and notifications related to this disease is continue to increase each year. Risk related to this infection is highest in people aged 15 to 24 and almost 80% cases occurred in this age group. Almost 2200 womens were diagnosed in 2011 with chlamydia in per 100,000 people. However, almost 50% of men and 80% of women diagnosed are asymptomatic and because of this it is typical to reporting them. Usually, womens are more likely to diagnose as compared to men, and this trend is revered in the age of 30 years. It is agreed by experts that in case of chlamydia most the increase is related to diagnosing testing. Advanced technology created more accurate tests because of which it is easy to identify the infection. Numbers of tests are introduced for identifying these infections. More number of people used these tests for the purpose of testing the infections, and unfortunately more positive results are found. Detecting more n umber of infections is considered good thing because it became easy to cure this infection, but it is also considered as change which considered more dramatic as compared to reality. Generally, chlamydia is established because of oral sex, anal, vagina, and very often touching an eye with the hand if such hand has infected fluids on it. Women suffer bleeding between their periods or after sex, and pain in your pelvis or lower abdomen, or pain when urinating, and yellowish discharge with smell which is not unusual. Generally, there are no symptoms of this infection because of which it is hard identify this infection. It must be noted that almost 70-95% women with chlamydia experience no symptoms and in case of men almost 90% of men experience no symptoms of chlamydia (PopSugar, 2014). This infection is considered as bacterial infection which usually infects the prostate, urethra, testes in men and the cervix, uterus, and pelvis in women. It must be noted that chlamydia does not carry any symptoms with it and most of the people are not aware that they have this infection and they need treatment. In case it is left untreated then it can cause serious issues such as in men it can result in inflammation of the upper genital tract and infertility, and in case of women it can result in ectopic pregnancies, chronic pelvic pain and infertility. It also increases the chances of contracting with other infections too such as HIV. Treatment related to this infection is critical as both patient and their partner will be treated with antibiotics before they have sex again, and get tested again in almost 3-4 months for the purpose of ensuring that it is completely gone (ABC, 2016). Statics related to Chlamydia: In 2011 this infection is the most reported infection in Australia, as almost 79833 cases related to this infection was found in people or almost 435 cases in every 100,000 population. This was almost 7 times hike in the rates of reportable STI gonorrhea. This rate is almost more than tripled in past decades, which increase from 130 notifications per 100,000 in 2001. As stated, in the year 2011 more women were found suffering from chlamydia as compared to men. Almost 43636 women were diagnosed with the infection as compared to 33197 men who were aged between 15 years and above. Women aged between 15 and 19 years had increasing rates of diagnosis in 2011 with 2228 per 100,000 receive positive diagnosis. Overall, chlamydia diagnosis for men and women aged between 15 and 29 years accounted for 82% of diagnoses for the whole population (ABC, 2017). Reasons behind chlamydia and its effect on health: Chlamydia is considered as most common sexual infections in Australia, and there are number of people who did not know that this infection is increasing at the alarming rate. In the period of 1980, AIDS is epidemic and now message related to safe sex has given to deaf ears and because of which rates related to STI is increased. Leaders of the STI is chlamydia which is a bacterial infection and very common in both men and women. As per the experts, increase in the rate of chlamydia is not a topic of distress because now we are diagnosed this issue because of which rates are increasing. Experts further stated that young people are happy to be tested for chlamydia, because it is the only way through which this disease can be reduced, and doctors also offered young people to test this disease on the ground that if we test it more than we found it more. The main reason behind this disease is the increasing number of teenage sex, and now age of first intercourse is reduced as now average age of first sex is 15 years, and in the old generation this age is almost 18 or 19. In other words, now people have few more years to infect. Numbers of evidences are present which states that teenagers are having more sex and especially girls. Generally, this infection is spread through vaginal and anal intercourse and sometimes through oral sex also, and when infected mother give birth to new born then this disease is transmitted in them as well. This infection result in eye and lung infection of new born. The best way to prevent this infection is use of condoms (Healthed, n.d.; Assefa, Ishak, Stevens, Fergussen, Giles, 1998). While it must be noted that there are some other factors also which increase the risk of Chlamydia such as biological, social, cultural, and economic factors. Teenagers who are belong to neutral and single parents are more attracted to the intercourse as it increases the chance of ignorance. Some biological factors are also there such as new born child gets this infection from their mothers. When at initial stage safe sex message has been sent then it is found that almost 80% of first sexual experience is with condoms, and the main problem is continued use. One of the issues related to younger people is that if they have been with their partner for longer time then condoms may be disappearing. After few times with their partners, they change their partners and this result in more chances of attracting STI. As per one recent survey almost 80% women who are aged 16 to 25 have unprotected sex almost half of them did not even use condoms while having last sexual encounter. Government mad e various policies to deal with these issues such as using condoms, does not have sex without proper knowledge, having protected sex, take medical help in any unusual situation, etc. This infection is usually clinically silent and increases the risk factors for chronic disease. Especially in the age of 15 years, to an emphasis on screening as an important part of the clinical care that generalist remote primary health care service providers opportunistically offer (Faggan, Cannan, Crouvh, 2013). Above stated factors affect the policies and measures taken by government, as it is really difficult to change the influence of cultural factors and biological factors, and the only way through which this can be reduced is by awaking the people about the severe causes and held sex education classes for young people (Medscape, 2014). Conclusion: After considering the above facts, it is clear that STI are more common in young people especially aged 15-24 years as compared to other age groups. Such infections endanger the long term health of youth such as it is not possible to cure some STI and some STI damage the reproductive system if it is not treated. The main reason behind this disease is the increasing number of teenage sex, and now age of first intercourse is reduced as now average age of first sex is 15 years, and in the old generation this age is almost 18 or 19.

Shark Facts There are several hundred species of sharks, ranging in size from less than eight inches to over 65 feet, and native to every marine environment around the world. These amazing animals have a fierce reputation and fascinating biology. Fast Facts: Sharks Scientific Name: ElasmobranchiiCommon Name: SharksBasic Animal Group: FishSize: 8 inches to 65 feetWeight: Up to 11 tonsLifespan: 20Ã¢â¬â150 yearsDiet:Ã CarnivoreHabitat: Marine, coastal and oceanic habitats worldwideConservation Status: 32% are Threatened, with 6% as Endangered and 26% as Vulnerable on a global basis; 24% are Near Threatened Description AÃ cartilaginous fishÃ has a body structure formed of cartilage, instead of bone. Unlike the fins of bony fishes, the fins of cartilaginous fish cannot change shape or fold alongside their body. Even though sharks dont have a bony skeleton like many other fish, they are still categorized with other vertebrates in the Phylum Chordata, Subphylum Vertebrata, and Class Elasmobranchii. This class is made up of about 1,000 species of sharks, skates, and rays. Sharks teeth donÃ¢â¬â¢t have roots, so they usually fall out after about a week. However, sharks have replacements arranged in rows and a new one can move in within one day to take the old oneÃ¢â¬â¢s place. Sharks have between five and 15 rows of teeth in each jaw, with most having five rows. A shark has tough skin that is covered by dermal denticles, which are small plates covered with enamel, similar to that found on our teeth. Stephen Frink/Iconica/Getty Images Species Sharks come in a wide variety of shapes, sizes and even colors. The largest shark and the largest fish in the world is the whale shark (Rhincodon typus), which is believed to reach a maximum length of 65 feet. The smallest shark is thought to be the dwarf lantern shark (Etmopterus perryi), a rare deep-sea species which is about 6 to 8 inches long. Habitat and Range Sharks are found from shallow to deep sea environments, in coastal, marine and oceanic environments the world over. Some species inhabit shallow, coastal regions, while others live in deep waters, on the ocean floor and in the open ocean. A few species, such as the bull shark, move easily through salt, fresh and brackish waters. Diet and Behavior Sharks are carnivores, and they primarily hunt and eat fish, sea mammals like dolphins and seals, and other sharks. Some species prefer or include turtles and seagulls, crustaceans and mollusks, and plankton and krill in their diets. Sharks have a lateral line system along their sides which detects water movements. This helps the shark find prey and navigate around other objects at night or when water visibility is poor. The lateral line system is made up of a network of fluid-filled canals beneath the sharkÃ¢â¬â¢s skin. Pressure waves in the ocean water around the shark vibrate this liquid. This, in turn, is transmitted to jelly in the system, which transmits to the sharkÃ¢â¬â¢s nerve endings and the message is relayed to the brain. Sharks need to keep water moving over their gills to receive necessary oxygen. Not all sharks need to move constantly, though. Some sharks have spiracles, a small opening behind their eyes, that force water across the sharkÃ¢â¬â¢s gills so the shark can be still when it rests. Sharks that do need to swim constantly have active and restful periods rather than undergoing deep sleep like we do. They seem to be Ã¢â¬Å"sleep swimming,Ã¢â¬ with parts of their brain appearing less active while they remain swimming. David Jenkins/Robert Harding World Imagery/Getty Images Reproduction and Offspring Some shark species are oviparous, meaning they lay eggs. Others are viviparous and give birth to live young. Within these live-bearing species, some have a placenta just like human babies do, and others do not. In those cases, the shark embryos get their nutrition from a yolk sac or unfertilized egg capsules filled with yolk. With the sand tiger shark, things are pretty competitive. The two largest embryos consume the other embryos of the litter.Ã While nobody seems to know for certain, it has been estimated that the whale shark, the largest shark species, can live up to 150 years, and many of the smaller sharks can live between 20 and 30 years. Some sharks actually lay eggs while others give birth. Cludio Policarpo / EyeEmÃ / Getty ImagesÃ Sharks and Humans Bad publicity around a few shark species has doomed sharks in general to the misconception that they are vicious man-eaters. In fact, only 10 out of all the shark species are considered dangerous to humans. All sharks should be treated with respect, though, as they are predators, often with sharp teeth that could inflict wounds (especially if the shark is provoked or feels threatened). Threats Humans are a greater threat to sharks than sharks are to us. Many shark species are threatened by fishing or bycatch, which leadÃ to the deaths of millions of sharks each year. Compare that to shark attack statistics- while a shark attack is a horrifying thing, there are only about 10 fatalities worldwide each year due to sharks. Since they are long-lived species and only have a few young at once, sharks are vulnerable to overfishing. Many are caught incidentally in fisheries targeting tunas and billfishes, and a growing market for shark fins and meat for restaurants is also impacting different species. One threat is the wasteful practice of shark-finning, a cruel practice in which the sharks fins are cut off while the rest of the shark is thrown back in the sea.Ã The shark fin trade is one of the threats humans pose towards sharks. Ã IN2 Focus Media/Getty ImagesÃ Conservation Status The International Union for Conservation of Nature (IUCN) has assessed over 60 species of pelagic sharks and rays. About 24 percent are classed as Near Threatened, 26 percent are Vulnerable, and 6 percent Endangered on a global basis. About 10 are classed Critically Endangered. Sources Camhi, Merry D. et al.

Death of Sun - 1 page discussion - Essay Example ve until this time, it is therefore clear that the use of space shuttles and similar vehicles to transport humans to outside of Earth will have become mass produced. It is therefore sensible to conclude that there should be technology which is advanced enough to propel all human beings to a refugee planet in outer space. However, the only problems that might be encountered here would be the probable fight for who will be on those vehicles first, plus the money needed for it. Human greed might then become the reason for the probable failure of this evacuation plan. Anyone anywhere should therefore cooperate with the government and the media on what to do, although this would be highly impossible because of panic. There is nothing much anyone can do at this time but to keep their ears glued to the news, to pack up all their essentials, and to say their prayers. They should then await any directive from the government. They should then await any directive from the government for a possible relocation to where they should be transported to space. If the sun dies out, then the whole solar system should also die, and so only an exoplanet could be the answer.
