Invasive Species - Melaleuca Tree essays

Invasive Species - Melaleuca Tree essays Introducing a nonnative species into an environment can cause some unexpected problems to the habitat and to native species. Although some introduced species are beneficial, such as food crops, game animals and pets, others can have a negative effect on the environment. Fifteen percent of species introduced have become invaders causing devastation to farms, health hazards for humans, invasion of natural areas, and the replacement of native species. If a plant or animal is introduced to a new area with similar plants or animals it causes competition for food or space. One species can be eliminated because of this. An example of a nonnative species being introduced into the United States and causing unforseen problems is the Australian melaleuca tree being introduced to Florida. The melaleuca tree is an ornamental plant that grows to be about eighty feet tall. The bark of the tree is spongy and its leaves are up to five inches long. The flowers of the melaleuca tree are white and small and the fruit that the tree produces are woody capsules with many seeds. This tree was introduced into Florida swamps in the 1880's because people wanted to dry up the useless swamps. They have since become a problem for the everglades because they invade moist open habitats forming dense and often impenetrable stands of trees. Native wildlife in these areas are threatened because the melaleuca trees crowd out beneficial native plants. The tree can spread very fast because it produces large amounts of seeds and most of the seeds that spread grow into large trees. Only fifty years after the tree was introduced into the United States it had already spread over hundreds of thousands of acres. By 1967, it was in Everglades National Park, and in 1993 it covered 488,000 acr es in south Florida. Melaleuca trees produce hot crown fires that result in mortality for native trees and pose a threat to people and animals in th ...

Mamenchisaurus - Facts and Figures

Mamenchisaurus - Facts and Figures Name: Mamenchisaurus (Greek for Mamenxi lizard); pronounced ma-MEN-chih-SORE-us Habitat: Forests and plains of Asia Historical Period: Late Jurassic (160-145 million years ago) Size and Weight: Up to 115 feet long and 50-75 tons Diet: Plants Distinguishing Characteristics: Unusually long neck, composed of 19 elongated vertebrate; long, whiplike tail About Mamenchisaurus If it hadnt been named after the province of China where it was discovered, in 1952, Mamenchisaurus might better have been called Neckosaurus. This sauropod (the family of gigantic, herbivorous, elephant-legged dinosaurs that dominated the late Jurassic period) wasnt quite as thickly built as more famous cousins like Apatosaurus or Argentinosaurus, but it possessed the most impressive neck of any dinosaur of its kindover 35 feet long, composed of no less than nineteen huge, elongated vertebrae (the most of any sauropods with the exception of Supersaurus and Sauroposeidon). With such a long neck, you might assume that Mamenchisaurus subsisted on the uppermost leaves of tall trees. However, some paleontologists believe that this dinosaur, and other sauropods like it, was incapable of holding its neck to its full vertical position, and instead swept it back and forth close to the ground, like the hose of a giant vacuum cleaner, as it feasted on low-lying shrubbery. This controversy is closely tied to the warm-blooded/cold-blooded dinosaur debate: its difficult to imagine a cold-blooded Mamenchisaurus having a robust enough metabolism (or a strong enough heart) to enable it to pump blood 35 feet straight up into the air, but a warm-blooded Mamenchisaurus presents its own set of problems (including the prospect that this plant-eater would literally cook itself from the inside out). There are currently seven identified Mamenchisaurus species, some of which may fall by the wayside as more research is conducted on this dinosaur. The type species, M. constructus, which was discovered in China by a highway construction crew, is represented by a 43-foot-long partial skeleton; M. anyuensis was at least 69 feet long; M. hochuanensis, 72 feet long; M. jingyanensis, up to 85 feet long; M. sinocanadorum, up to 115 feet long; and M. youngi, a relatively runty 52 feet long; a seventh species. M. fuxiensis, may not be a Mamenchisaurus at all but a related genus of sauropod (provisionally named Zigongosaurus). Mamenchisaurus was closely related to other long-necked Asian sauropods, including Omeisaurus and Shunosaurus.

Child Law Essay Example | Topics and Well Written Essays - 1000 words

Child Law - Essay Example The Child Abduction Act addresses the offence that is child abduction. In this case, an abductor could be a parent, or not. The act also provides that an individual who is involved with a child below sixteen years of age is deemed to have committed an offence at such a time as when he either sends or takes a child away from the United Kingdom, and not taking the trouble of seeking proper consent. Once a person is deemed to be a parent to such a child, the law recognizes such a person as being connected to the child in question (Wardle & Nolan 2002). In a situation whereby such a child was born at a time when his parents had not yet married, but evidence exists without any reasonable doubt that such a person is the father to the child, or a guardian for that matter, this is still counted as a connection with the child. The same case applies when such a person has been awarded the child’s custody (Wardle & Nolan 2002). The Child Abduction Act states that the consent to taking away a child has to be sought from the mother to the child, his father (only in a case where such a father enjoys parental responsibilities), the child’s guardian, or another individual who has been favoured by a residence order to take care the child. The same case applies to an individual that has been granted custody of the child in question (Wardle & Nolan 2002). According to the Child Abduction Act, an individual may send or take a child away from United Kingdom and not be seen to have committed any offence under certain circumstances. For example, an individual who has had a residence order ruled in favour of, in as far as the custody of the child is concerned gets exempted, or if an individual wishes to send or take such a child from outside of the United Kingdom for no more than a month’s time (Lyster 2007). The Child Abduction Act may be said to take into account the welfare of the child. For example,

Experience economy Essay Example | Topics and Well Written Essays - 3250 words

Experience economy - Essay Example Commerce includes all those activities, which are connected with trade and auxiliaries to trade such as transport, warehousing, insurance and banking and finance. Trade involves buying and selling of goods and its purpose is to bridge the gap between persons, i.e. the producers and the consumers can concentrate on their own occupations and at the same time buy goods to satisfy their consumption needs. The farmers can both enjoy each other's products with the help of traders. For example there are different types of cotton; jute, hides and skins are supplies to the producers of cotton textiles, gunny bags and shoes respectively. At the same time manufactured goods, which have been produced with the raw materials, are supplied to the consumers. Producers buy raw materials, machinery and equipment as well as stores and spare parts for machinery fro trading agencies and consumers buy practically all articles required for their daily use from traders. Goods are produced on a large scale in anticipation of demand. The markets for products are now spread over the length and breadth of the country and even extended to countries across the international borders. Hence direct sale of goods by the producers to the consumers is not possible. Without the help of traders and merchants engaged in trade it would be impossible for the system of large-scale production to continue. The trader involved in the actual operation of purchasing goods from producers and selling them to consumers. Traders and consumers are interdependent. Importance of trade Trade is of great significance for production as well as consumption of goods. It is through trade that goods produced at particular places are equitably distributed among users.

Development in different sectors like Information Technology, Steel industry, etc., has resulted a sharp rise in the usage of harmful substances.

Excellence in Engineering Education :: Education Engineer Educating Essays

How should we describe the excellent engineer and what kind of education is demanded by such a person? Several issues are involved. One of these is the character of our times; that is, the best engineer out of the "science engineering" model of the 1950s may have little value in the early 21st Century. Another issue is the concept of education. How do education and training differ and how is excellence achieved? Finally, clearly, there is the issue of what we would expect of an engineer who is truly excellent. Fortunately for us, ABET (Accreditation Board for Engineering and Technology) seeks to define the excellent engineer and the excellent engineering program by outlining a number of criteria that should be met by any accredited program in engineering education. It is important to note, at the outset, that ABET begins with an overarching criterion that "engineering programs must prepare graduates for the practice of engineering at a professional level." (My emphasis) This must mean something more than mere vocational training. As a professional, the engineer must exercise considerable autonomy and use intelligent individual judgment. The professional engineer can be no mere employee; he/she must become a partner in the development of technology. By its very nature a professional partnership involves certain viewpoints, methods, and standards developed by the community of professionals, who have common interests and objectives, and these must stand independent of those who would employ o r otherwise seek the service of these professionals. Three of the five criteria developed by ABET recognize aspects of the educational institution that, I suspect, all will agree with without much hesitation. Students of high quality must be attracted and served well. Faculty of high quality must be attracted and retained. Educational objectives must be stated clearly and publicly; some form of evaluation must be in place to assure that these objectives are achieved. The one worrisome aspect of the new ABET criteria is what appears to be an overwhelming emphasis on quantitative assessment, phrased in terms of outcomes. While it is one thing to plan for and hope for significant outcomes, it is another to expect that genuinely desirable outcomes will always be so "objective" that quantitative assessment is remotely possible. At the very least, there should be some allowance for the obvious fact that certain outcomes take longer than others to be realized. It is true, of course, that the longer an outcome takes, the more complex are the f actors that contribute to it.

No More Couch Potatoes Essay

There is no doubt that there is too many obese people in this world, and that is clearly a problem, but we are focusing on the wrong things in our searching for a solution. It is not the overweight itself and the thinking of a better look when all the kilos are gone, no, it is a good physicality that is the main drive or motivation that leads to a good and forever being los of weight. Too many of the obese people do not keep being thin when they have lost weight, because they are not supported on their personality, the particularly obese young boy or girl, have being abused and bullied because of their overwhelming weight, and look. That breaks the physical motivation in those young kids, and makes them take a part of this way of being treated, they accepts it and puts on a role as the â€Å"fat dude†. Personality and losing weight has to expand i the same tempo to keep the necessary motivation, not just to loose more weight, but to get a stronger and more confident personality. One of the newest answers to the obesity problem, is the â€Å"TV-cycle†, a bicycle connected to the TV, so to watch television, the kids now has to get a movement in the pedals, if not, the TV will turn off. That is not a way to get rid of the obesity. Treating the obese kids otherwise than regularly weighting kids in average teenage activities is giving them the fat-kid role, and that will not strength their outer persona. Respect and accept from other kids is important to get the essential feeling that creates a confident personality, a person who believes in him/herself. Wathing Tv, playing computer, and eating fastfood, those things are not the main problems, they are just a part of what the physical breakdown effects. Everyone do those things once in a while, and everyone should do it if they want, but everything is healthiest in small doses, and that is on thing that the obese kids has to learn, i a way so it feels natural in their minds to think of exercising, healthy food and so on. Once i had a rule that everytime i eated couch potatoes, i also took an apple from our fruit bawl, and everytime i had been surfing on the internet for too long, i went to my garden and played football. Everyone can do that. Everyone do like some kind of good and healthy food, and everyone do know how to run, kick to a ball, hop, whatever. If we just treat everyone the same, there will be a place to evolve, from overweight to regular weight, and from unconfident to confident about ourselves, and our surroundings.

Disengagement Theory Is The First Formal Theory Of Aging

Disengagement theory is the first formal theory of aging. It was first proposed in 1961 by Elaine Cumming and William Hendry. They both were researchers from the University of Chicago. The two developed their theory in their book Growing Old: The Process of Disengagement. In the book they criticized the implicit theory that people can adjust, be satisfied, and happy in old age. They can also be physically involved and remain active throughout their lives. â€Å"Cumming and Henry argued that normal aging involves a natural and inevitable mutual and inevitable mutual withdrawal or disengagement, resulting in decreasing interaction between an aging person and others in the social system he belongs to.† Because of the inevitability of death, the society and the individual mutually server their ties in advance so that the death of the individual will not be disruptive to the social system. The disengagement theory results in decreasing interaction between aging person and social s ystem. Disagreement occurs when the individual becomes aware of the shortness of life and the amount of time left. The individual wants to disengage by reducing the number of roles the individual plays. One of the most controversial things about this theory would be that the idea of disengagement was a universal meaning. Universal means it happens everywhere and in all historical areas. Inevitable, means that it happens sometimes to everyone.
