History of the Jet Ski

History of the Jet Ski Personal water craft have been around for more than half a century. The â€Å"Jet Ski,† however, is a trademark used by Kawasaki for its line of personal motorized water craft. Although the word Jet Ski has now become a more generic term describing all personal watercraft, well use it to refer specifically to the Kawasaki vessels. Early Years The earliest water scooters- as they were originally called- were introduced to Europe in the mid 1950s by motorcycle makers looking to expand their markets. The British company Vincent produced some 2,000 of its Amanda water scooters in 1955, but it failed to create the new market Vincent had hoped for. Despite the failure of European water scooters to catch on in the 1950s, the 60s saw continued attempts at tinkering with the idea. The Italian company Mival introduced its Nautical Pleasure Cruiser, which required users to hang onto the craft from behind. Australian motocross enthusiast Clayton Jacobsen II decided to design his own version so that its pilots would be standing up. His big breakthrough, though, was switching from the old outboard motors to an internal pump-jet. Jacobsen made his first prototype out of aluminum in 1965. He tried again a year later, this time opting for fiberglass. He sold his idea to the snowmobile manufacturer Bombardier, but they failed to catch on and Bombardier gave up on them. With patent back in hand, Jacobsen went to Kawasaki, which brought out its model in 1973. It was called the  Jet Ski. With the benefit of Kawasaki’s marketing, the Jet Ski won a loyal audience as a way to waterski without the need  for a boat. It was a small audience, however, as remaining on board while standing up- especially in choppy water- remained a challenge. Jet Skis Go Big The next decade planted the seeds for an explosion in the  popularity of personal water craft. For one thing, new models were introduced that let  riders do what they could do back on the old water scooters. The ability to sit down helped pilot stability. New designs not only improved stability further, but they allowed for two riders at a time, introducing a social element to personal water crafts. Bombardier got back into the game with the introduction of the Sea-Doo, which went on to become the best-selling personal watercraft in the world. With further advances in engine technology and emissions, today’s personal water craft enjoy new-found success in every metric. They can go faster than ever, reaching 60 miles an hour. And they now sell more than any boat in the world. Jet Ski Competitions As the popularity of personal water craft started to take off, enthusiasts started to organize races and competitions. The premiere racing series event is the  P1 AquaX, which launched in the United Kingdom in May 2011. London-based sports promoter Powerboat P1  created the racing series and expanded to the United States in 2013. And by 2015, as many as  400 riders from 11 countries had signed up to compete in an AquaX event. The organizers are looking to expand to other countries.

The Meaning of To a T

The Meaning of To a T The Meaning of To a T The Meaning of To a T By Mark Nichol The expression â€Å"to a T,† as in â€Å"That suits you to a T!† is often mistakenly written or said as â€Å"to the T† (or â€Å"to a tee† or â€Å"to the tee†). This type of alteration occurs often in idiomatic phrases (note â€Å"all of the sudden† and â€Å"for all intensive purposes,† among others). In today’s anarchic publishing environment, writers are free to consciously or unconsciously style such phrases however they choose, but careful writers will preserve prevailing norms. But what, exactly, is a â€Å"T†? None of the various proposed origins of â€Å"to a T† is definitive, but only one makes any sense. The opinion that it refers to how well a T-shirt fits is nonsensical: The term for a collarless, short-sleeved shirt is less than a hundred years old, and the expression dates to the late 1600s. That also disqualifies the more plausible theory that it alludes to the precision a T square, the T-shaped drafting tool, enables; the first attested use in print of the tool’s name postdates the first use of the phrase by nearly a century. And is has nothing to do with the golf implement known as the tee, which has always been spelled as such (though the spelling error â€Å"to a tee† goes back hundreds of years). Most likely, the phrase is descended from the expression â€Å"to a tittle.† A tittle is a small mark used in orthographic details, such as the dot over an i or a j or a diacritical mark such as an accent mark, and the sense is â€Å"to the smallest detail.† But why isn’t the expression styled â€Å"to a t†? That’s because uppercase letters are the default setting when using a letter to represent something. Report cards have As and Bs (but, the recipient hopes, no other capital letters), the force of gravity is expressed as a multiple of Gs (the capital letter is the scientific symbol for gravity), and X, not x, marks the spot. (We also use uppercase letters such as S and V to denote shapes- though, like X as a location marker and the other uses referred to above, they should not be italicized in those contexts, because they do not literally represent letters.) There are a couple of exceptions: The context of â€Å"Dot your i’s and cross your t’s† and â€Å"Mind your p’s and q’s†- if one accepts the contested interpretation that the latter originally referred to easily confused letters- requires lowercase letters. Does teetotaler have any connection? The word for someone who abstains from alcohol goes back nearly two centuries but originally referred merely to intensification of one’s feelings about being totally devoted to something, with tee attached as a form of reduplication. But as the differing spelling indicates, this word has nothing in common with the expression â€Å"to a T.† Want to improve your English in five minutes a day?

Language Change Article Example | Topics and Well Written Essays - 750 words

Language Change - Article Example They may be just expressing their opinions and fears rather than being concerned about the health of language itself. The article says that language change is triggered by social factors. These social factors make use of the existing gap in the structure of the language. The author believes that language change is of two major types. She gives an example of changes in English language. According to her, while the loss of‘t’ is a disruptive change, the loss of ‘h’ has a therapeutic effect on the language. The article then moves over to linking language change in humans to that of whales. During the breeding season, whales change their song. Change is not a correct word as only modification occurs in their song. When an accurate observation was made about the modification, it was seen that new sequences were created by joining middle and end of the phrases, omitting the middle part. This is very similar to change of language in human beings. The purpose of this example is to point out that human beings are not alone in the phenomenon of language change. Then the first question of the article is asked. Should language change be measured with the words like progress and decay? The author believes that arguments about ‘progress’ or ‘decay’ in language have tended to reflect the religious or philosophical preconceptions of their proponents. On the other hand there are people who base their language theories on the Darwin’s theory of evolution. Charles Darwin believed that a shorter and easier form of language gained an upper hand over other languages. So does this mean that a language that expresses more in fewer words is superior over others? The author says that this shouldn’t be the yardstick to measure the superiority of a language because shorter and easier forms of language often result in confusing homonyms. Hence, while analyzing a language change, both religions and

Experiences of Morrison concerts - Assignment Example The piano trio, which consisted of a piano, a cello and a violin, was excellent, as was the string quartet with the special guest Mack McCray on the piano. The overall feeling of both of these musical ensembles was that there was a certain lightness to the playing, at least in spots. I really enjoy the cello, especially, as it tends to have such rich tones, and it complemented the piano on the Calyx piano trio very well. As did the violin. What struck me was that, between both concerts, the music was very similar. There were periods where the music sounded like folk music, like Hungarian folk music, and then there were spots were I could detect a slight Celtic bent to the music. Then, there were periods of the concert when the music sounded more like modern music, with a hint of Igor Stravinsky in some of the chords. That is, there were periods where the music became allegro and the musicians played them with great passion and verve. Mack McCray was an amazing pianist. He played with a great flow and passion, and there was not a note that was out of place. Sometimes it seemed that the concert belonged to him, more than the string quartet, but there were other spots where the quartet dominated and the piano receded into the background. I also enjoyed listening to the different influences that were heard throughout the perfomances. For instance, in the Schumann's Piano Quintet in E Flat Major, which was one of the pieces that was played in the St. Petersburg String Quartet, there were evidently influences that were classical and romantic in origin. The piece went from a lugubrious opening with the cello dominating, then went more into the lighter parts of the piece where the piano was blended in harmoniously with the strings of the other instruments. There were periods that sounded like a waltz, but this was only in spots. The piano in the middle of the piece had an air to it that sounded very polished, and I recognized that the piece had a quality to it that spo ke to me. I was also very interested in the Benjamin Britten piece, as I had studied his music extensively, and I knew of his operas. This piece started out with an almost discordant tone to the strings, and it was definitely the product of a modern composer. That is, the staccato string that can be heard throughout the first part of this piece, combined with the discordant tones are those which are not typically heard in the classical or romantic or baroque styles. This piece actually was the piece that liked the least, because I am not a fan of the discordant style and there was something about it that hearkened to movies with American Indians. And this is what the piece sounded like – music that should be played in American Indian movies. It was a little difficult to listen to, but I do know that this is a style that many people enjoy. The second movement of this piece, however, was much better, and struck a much more harmonious tone. What was striking, though, about the B ritten piece is that it sounded almost spare compared to some of the other pieces which were played. There were very little flourishes that one is used to hearing from a string quartet with a piano. The Franck piece, which as Piano Quintet

Ethics of Full Disclosure of Security Holes Essay -- Hackers Internet

Ethics of Full Disclosure of Security Holes Introduction Security breaches are making big headlines nowadays, and Microsoft is leading the charge. Its flagship operating systems and office suite are so bulky and complex, that it is impossible to be bug-free. The system administrators (the white hats) are up to their noses plugging all the holes from super hackers (the black hats). Yet they are also facing attack from another front – those that post vulnerabilities on the internet (the gray hats). The gray hats are hackers that find security vulnerabilities and post them on the internet, forcing system administrators to patch up the holes. Usually, they inform the vendor ahead of time. Then, if they deem the company is not taking them seriously, and malicious hackers will exploit the threat, they post it on a forum. Though acting in good faith, the ethics of full disclosure of security holes are in debate, including: how full disclosure can cause more harm then good, how long vendors should be allowed to fix the problem, and liabilities for posting on the internet. Issue 1: Full disclosure of security-related information can inflict more damage than good. You are showing people how to break into systems. The debate about vulnerability-disclosure policies involves two main parties. Researchers at security companies say they want to get their latest findings out quickly to hasten software makers' response to bugs. Software makers, on the other hand, say they aren't given enough time to deal with a problem, and that publicizing it simply alerts malicious hackers to an opportunity. There are super hackers out there who find security vulnerabilities, then write a script up on the internet, with one or two l... ...on't publish code, 17 Oct. 2001, CNet News.com, 11 Mar. 2004, 6.

African Wild Dogs

Lycaon pictus, the scientific name for the African Wild Dog, literally translates into â€Å"painted or ornate wolf† (â€Å"Lycaon pictus — Details African Wild Dog†). African Wild Dogs are some of the most beautiful and social canines in the world, but, sadly, this species is endangered. This essay will focus on a basic description of the African Wild Dog, along with the threats it faces and the projected outlook for this species. (â€Å"Lycaon pictus — Details African Wild Dog†). The African Wild Dog has a slender body with long, muscular legs (â€Å"Lycaon pictus — Details African Wild Dog†).Typically, they will weigh between forty and eighty lbs. and can be anywhere from three and a half to five ft. long (including the length of the tail). African Wild Dogs are usually between two and two and a half ft. tall at the shoulder. The males also tend to be slightly larger than the females. Compared to wolves or coyotes, they are very lea n and tall. Unlike other canines, the African Wild Dog has only four toes on its front feet, as opposed to the typical five. This is because their dew-claw is missing.Other distinctive qualities are their large, round ears. (â€Å"Lycaon pictus — Details African Wild Dog†). It is said that these ears are essential for hunting, during which a pack may use long distance vocal calls (G. Rhodes, and R. Rhodes). These ears also help with heat loss and regulation (â€Å"Lycaon pictus — Details African Wild Dog†). However, an African Wild Dogs most distinctive quality is its coat; this species has a coat blotched in yellow, gray, black, white, and brown (â€Å"Lycaon pictus — Details African Wild Dog†).Most of the variation in color is on the body and legs (Creel, and Creel). The coloration on the dogs faces are all very similar, with a black muzzle shading to brown on the cheeks and forehead, a black line extending up the forehead, and blackish-br own on the backs of the ears. There is never white on the head. The back part of the head and the top of the neck are consistently brown or yellow. However, colors on the body and legs are unpredictable. (Creel, and Creel). The fur on its bushy tail is almost always white (â€Å"Lycaon pictus — Details African Wild Dog†).An African Wild Dog’s fur is slightly longer around the head and body, and shorter on the legs (â€Å"African wild dog (Lycaon pictus)†). However, wild dogs tend to have sparse hair, though there is variation among individuals (Creel, and Creel). This variation is related to age—young pups and dogs have more hair than adult dogs, and old dogs can become almost hairless. Hair is particularly lost on the head, which begins to look grey as the skin shows through. (Creel, and Creel). Underneath its fur, African Wild Dogs have blackish/grey skin (â€Å"Lycaon pictus — Details African Wild Dog†).Every wild dog has a differe nt patterned coat with all the individuality of a snowflake or a fingerprint. It is the coat that can allow scientists to tell each animal apart. There has also been evidence to suggest that the dogs are able to use their distinctive coats to tell each other apart; this is why dogs can easily identify other wild dogs that are not in their pack, or spate packs that might pose a threat. (â€Å"Lycaon pictus — Details African Wild Dog†). African Wild Dogs live in packs, and have a very unusual social system (â€Å"Lycaon pictus — Details African Wild Dog†).In their packs, only the dominant male and female are allowed to reproduce, which leads to alliances among dogs of the same sex. Packs can range anywhere from two to twenty seven individuals, and new packs form when a subgroup (usually females, and sisters) separate from their pack and join with another subgroup that is composed of males. The sisters typically separate once they reach sexual maturity. Afri can Wild Dogs usually hunt in the cool of dusk and dawn in order to avoid other predators like lions, and the pups are usually allowed to eat first after prey has been killed. (â€Å"Lycaon pictus — Details African Wild Dog†).As stated previously, only the dominant male and female are allowed to reproduce (â€Å"Lycaon pictus — Details African Wild Dog†). However, all African Wild Dogs will reach sexual maturity in about two years, though mating does not usually occur until much later. The dominant female can give birth during any time of the year, though birthing tends to be more common between March and June. Gestation averages around ten weeks, and the litter averages around ten pups, though twenty pups have been recorded in one litter. The African Wild Dog has one of the largest litters in the canine world.Pups are born in a den (usually an abandoned aardvark hole) and will stay there with their mother for three-four weeks. While the mother and pups a re refined to the den, other pack members will regurgitate food for them. Once the pups mature enough to leave the den, they become the responsibility of the whole pack, often nursing off of females that are not their mother. However, pups are weaned anywhere from one-three months after birth. It generally takes twelve-fourteen months before another litter is born. (â€Å"Lycaon pictus — Details African Wild Dog†).The African Wild Dog (which has a life expectancy of about ten years in the wild) typically lives in savannas (â€Å"Lycaon pictus — Details African Wild Dog†). Savannas are found on either side of the equator on the edges of tropical rainforests most typically in Africa, though also occurring in select parts of South America and Australia (â€Å"Savanna†). In savannas, it is warm all year round, and there is not enough rainfall to support a forest. During its dry season, a savanna will only receive an average of four inches of rain fall. However, during the wet season, a savanna might get up to twenty five inches.In savannas, there is a lot of grassland, with scattered shrubs and isolated trees. Animal life includes many herbivores that consume grass, and also predators that control the herbivore populations. (â€Å"Savanna†). When African Wild Dogs are not breeding, they become nomadic and wander over large distances in search of prey; home ranges can be as large as 5,000 square kilometers, but are often much smaller (â€Å"Lycaon pictus — Details African Wild Dog†). These dogs are on the third trophic level because they eat herbivores, usually impala, antelope, and sometimes prey as large as wildebeests.There have been cases where a hungry wild dog will consume seventeen to nineteen lbs. of meat, or about 1/3 of its own weight. However, African Wild Dogs will never scavenge. Therefore, the African Wild Dogs fill a carnivorous predator niche, helping to regulate and control ungulate (animals w ith hooves) populations. (â€Å"Lycaon pictus — Details African Wild Dog†). African Wild Dogs are considered endangered because they have disappeared from much of their range (McNutt et al. ). These dogs are virtually nonexistent in West Africa, and greatly reduced in central and north-east Africa.The largest populations remain in southern Africa, and studies suggest that between 3,000–5,500 wild African Wild Dogs remain in Africa today. These dogs are in danger for several reasons, one of which being habitat loss and fragmentation. When their habitat is broken up, it increases contact with humans which can lead to issues such as poaching (when wild dogs prey on livestock) and road kill. These dogs need a lot of space to roam in search of prey (because of other predators that fill the same niche), so even reserves aren’t always effective because humans live right on the border.While smaller fenced reserves have been able to effectively contain these anima ls, fencing can be expensive and allow an outbreak of disease to wipe out the entire population. This is because wild dogs live at low population densities due to predation by lions and competition with hyenas. Such low population density makes the dogs susceptible to disease, and makes the epidemic that much more deadly. (McNutt et al. ). African Wild Dogs were declared vulnerable in 1986, and became endangered in 1990 and their population is decreasing (McNutt et al. . Wild dogs are legally protected across much of their range. However, this protection is rarely enforced and wild dogs are extinct in several countries despite severe legal protection. Conservation priorities include maintenance and expansion of habitat available to wild dogs, working with local people to reduce deliberate killing of wild dogs, establishing effective techniques for protecting small wild dog populations from infections, and continuation of long-term monitoring of populations in order to identify emerg ing threats.Re-establishment of extinct populations through reintroduction currently has a low priority in most areas, although natural recolonizations should be encouraged. (McNutt et al. ). Due to their decreasing populations, need for expansive space, and susceptibility to disease, it appears as if the future for this amazing species is grim. Not enough is being done to preserve this animal because laws are not being enforced, and humans are crowding and destroying their habitat.If African Wild Dogs are to survive, humans need to be extremely proactive in their protection of this species. African Wild Dogs should be reintroduced into habitat where they used to survive, and laws for the protection of these dogs need to be more regulated and enforced. These animals will also need a lot more habitat than they have now, and it will probably be very difficult to find the space for reserves necessary for the survival of this species. If humans truly decide to save the African Wild Dog from extinction, it can certainly be done, but it won’t be easy.

Cystic Fibrosis A Common Fatal Recessive Genetic Disease

What is Cystic Fibrosis? Dr. Polit describes Cystic Fibrosis, also referred to as CF, the most common fatal recessive genetic disease among white people. It is a hereditary disorder, also known as mucoviscidosis, which disturbs the lungs, as well as the digestive system, by blockage due to the creation of abnormally thick mucus. According to the U.S. National Library of Medicine, â€Å"This abnormal mucus can clog the airways, leading to severe problems with breathing and bacterial infections in the lungs. These infections cause chronic coughing, wheezing, and inflammation†. Due to the buildup and infections, scar tissue forms as well as lung cysts causing permanent lung damage. It is also very common for those with cystic fibrosis to suffer from digestive problems because of the blockages caused by thick, sticky mucus in the body. In the United States there are close to thirty - thousand people and seventy thousand people worldwide living with Cystic Fibrosis today, with the majority of them being over the age of eighteen. CF has over eighteen-thousand mutations, but most of the tests can’t always pick up on them, only the more common mutations of CF. By the age of two, over seventy-five percent of kids containing CF are diagnosed, making over one-thousand new cases of Cystic Fibrosis diagnosed every year.
