Powerful Ways to Open a Class Presentation

Powerful Ways to Open a Class Presentation Powerful Ways to Open a Class Presentation Many academic institutions require students to submit a slideshow presentation and discuss a topic in front of a group of people. The purpose is to help students improve verbal communication skills while providing information to several people in a single setting. While grading this project depends solely on the professor, a student who is able to deliver an informative and engaging presentation to the class has a better chance of getting a good grade. First impressions are key; the speaker sets the tone of the discussion. Audience members decide in the first minute whether they want to listen. To attract and maintain listener interest, here are powerful ways to open an introduction: Tell a joke. Start things on a positive note by making a non-offensive joke and engage your listeners. Propose a problem. To get attention, start by stating a current problem that most people can relate to and tie it into your discussion. Share a quotation. Choose a quotation from an important figure that relates to your topic. Recite it in a clear, modulated tone. Ask for a response. Start a discussion by asking a question like â€Å"How often do you use the Internet?† This question provides your audience the opportunity to participate before you continue the presentation. This also encourages them to later ask questions. Catch listeners off-guard. A radical statement or command can surprise people. For instance, if you are presenting a topic about conformity, first ask everyone to stand up. Then, ask why they did so. This opens the topic in an unexpected and unique manner. Tell a story. A personal anecdote or a tale can be used to set the tone of a presentation. Keep it brief and omit unnecessary details. This, ideally, helps listeners connect to you and your topic as they listen. Use a visual aid. When you begin your slideshow, allow your audience to comment on a photo or a video in the presentation to establish participation from the beginning. Choose the technique that works best for you when introducing your topic of discussion to the class. A slideshow presentation relies on both the careful construction of the conversation and its delivery. Capturing your listeners’ attention makes the presentation more likely to be active and engaging. No matter how interesting your topic, you may lose audience interest if you don’t make an effort to captivate them at the start. in Ontario provides a variety of services for all your academic needs. We are a team of professional writers who can help with presentations, including PowerPoint. Your slideshow will meet academic standards and save you time to practice your delivery.

Beach,Feast Essay Example | Topics and Well Written Essays - 1250 words

Beach,Feast - Essay Example The choice of the venue was apt and my siblings found it equally compelling. I continually struggled to get used to the nagging voice of Joyce, my younger sister. She asked many questions. Perhaps she thought I had been there earlier. Her sympathies could not lie with the fact that I remained silent in spite of her continuous effort to draw my attention. I was not going to tell her anything though I knew she would stay aloof if I did not. One morning, I decided to walk Joy around the beach. I glanced perfunctorily at her face and held her left hand. Dad and mum were chatting some distance away while Diana, my elder sister lazed by the cool, manicured beach. A few miles away, I could see a calm sizeable crowd. I decided to walk to the scene and witness the unfolding drama. It did not take us long before we were there. As soon as we arrived at the scene, it broke from its tranquil condition and erupted in song and dance. The crowd began to shout and yell with excitement. I came to real ize that there had been a music concert going on at the place for a week, and it was to continue for the next two weeks. A group of dancers hit the stage as a precursor to the next artist and blew away the crowd. The audience roared wildly, fully enveloped and massaged by the beats. The next performer in stage was a renowned artist, Luis Katrina, who stepped up as the audience went wild. She did not disappoint. She did a rendition of her latest song ‘New Dawn’ and left the stage. We did not stay longer either. We immediately left the place, but I promised to attend the concert for the rest of the days. The trip to Dubai was undoubtedly a gratifying one. Every morning we woke up to a new surprise as the beach was a beehive of entertaining events. I met new friends and learnt to play new games. I was never a proficient swimmer before, but the practice at the Jumeriah Beach helped improve my swimming expertise. In addition, I loved the dishes at the Mediah Jumeriah resort. Although grilled beef has always been my best dish ever since I was young, the one prepared at the resort was extraordinarily delicious. It smelled yummy too. We were not happy to leave the place when the three weeks elapsed. I gave a reluctant smile and entered my dad’s car. It had been all fascinating. Bobby’s send-off Party Bobby, my younger brother, attends an elementary school in a town away from home. His mid year holidays were coming to an end with barely a week to go. As usual, dad arranged for his send-off party. However, this one was to be slightly different. He had no inkling that dad had been arranging for his party. Bobby’s typical day is always a beehive of events. He gets up earlier than everybody else in the compound when it is still as dark as the yawning grave, starting his day in the gym. It is not out of character to find him in the physical exercise room as early as 3.00 am. After which, he continues with other activities in his plan includ ing playing basketball in the evening. This exact day, he came back in the evening from the basketball court looking all drained. His shirt was soaking wet and dirty. He was exhausted like an old worn-out shoe. As usual, he never talked to anyone until he took a cold bath. From the bathroom, he immediately rushed into the kitchen and found me holding a clove of garlic in my hands. If it were any other day, he would have had a nap as was accustomed to him. â€Å"

There Is an Ultimate Control of the Entire Universe Research Paper

There Is an Ultimate Control of the Entire Universe - Research Paper Example There Is an Ultimate Control of the Entire Universe Some of the explanation they have provided to counter the creation theory are quite amusing, since at some point they fail to provide a very comprehensive answer. This makes them still go back to the creation theory as the base for the existence of the world. Among some of the critics of creation theories are the scientific studies and some religious beliefs. Thesis Statement With the immense discrepancies and failures in the critical explanations offered, we are taken back to one origin of creation being the Supreme God. It is then that we accept the fact that the world and all that happens in it is controlled by a supreme being. This supreme creator, in my opinion, is God. Buddha Teachings The teachings of Buddha are quite fascinating. Buddha as we can say is the founder of the Buddhist religion. In the book, What Buddha taught by Ra?hula (1974) we are introduced into beliefs and convictions of Buddha about what happens to the world. In this text Buddha teaches about the attaining of enlightenment and perfectness. Through his life Buddha was able to find the path of liberation. Liberation in this case is the attainment of enlightenment through knowing the truth. Buddha teaches that human beings are the supreme beings of all the creatures, and as such they are the masters for themselves. They should not, therefore, be enslaved to any other supreme being. He goes further to point out that human beings have an ultimate control over their destiny, and there is no other being that is responsible for the destiny of a person. Buddha displays that he himself achieved the highest level of enlightenment and liberation. This made him to be seen as even superhuman and a perfect being. He attributes his achievements to his own will and intelligence. According to this teaching then, one can attain anything and can decide anything in life and get it. All that happens in the world is, therefore, through the mind and intelligence. The more one gets to be enlightened, the more they become intelligent, and the easier they find it to manipulate the world around them. So, it is not that there is some being somewhere that controls one’s life and destiny. It is your mind that can do all this and not any other thing. What the humans need to do is to go through the meditations taught in Buddhism, and through this meditation enlightenment will come in (Charles, 2012). The meditation as described by Buddha is the deep and continuous soul search that leads to the realization of the truth about the world. Through the process of meditation one gets insight because they look at things objectively and extract that thing from the environment. In doing this the thing is investigated carefully only by the mind of a person and not with the help of any other person or any other supernatural being. This is the point where Buddha takes the basis, that it is only human intelligence that is able to find truths about what is happening in the universe. This view is what b rings serious critics of the Buddha teachings. There is a being that is responsible for what happens in the universe, and that human beings have little control and influence of the happenings. The Critics of Buddha Teaching Though Buddha himself claims to have attained enlightenment through the medit

Conflict, Decision Making, and Organizational Design Research Paper - 2

Conflict, Decision Making, and Organizational Design - Research Paper Example 432). The real problem was that GM had developed too many levels of management. The number of corporate stuff was huge. So the decision making was slow and cumbersome, and, therefore, change was difficult. So the major challenge the new management faced was to eliminate the hierarchical levels and reduce the total number of managers. The top management expected that such a move will reduce operating cost, improve communication, and encourage innovation. Some analysts estimated a termination of 20,000 managers. The task was enormous (Jones & Mathew, 2007, p. 432). The board was of the belief that the shareholders’ interest can be served only by taking tough organizational design decisions. In 1993, GM announced its intention to cut 50,000 hourly and 24,000 salaried jobs and to close or consolidate 21 parts and assembly plants by 1995 to save money. The revolt by the board was an important mile stone in GM’s history. From that point on, GM’s performance improved every year (Jones & Mathew, 2007, p. 432). Conflict is not all about war, violence, and loss of life. By definition, a conflict is simply a disagreement among people on an issue. Conflicts can be small, as among two persons, or they can be large and complex, as among two or more countries. Conflict is a natural and normal part of human life and interaction. When communication to settle a conflict is constructive, the conflict is beneficial. Constructive approach stimulates new understandings and more socially just solution with stronger relationship. In case of a communication breakdown, conflict can lead to separation and hostility (Sughru, 2009, pp.7-8). While analyzing conflicts, it is better to break down the issue into five variables (Sughru, 2009, p. 10). First and foremost we need a complete picture of the actors and understand their direct or indirect role. In other cases, an actor may not be

Management And Conservation Of Seaweed Culture Environmental Sciences Essay

Management And Conservation Of Seaweed Culture Environmental Sciences Essay Seaweeds have been used practically in Chinese Herbs since 2700 BC in Emperor of Shen Nung. Reports show that since 300BC, seaweeds have been a part of the Japanese diet and mainly eaten in the Oriental countries like Japan, China, Korea and recently, in USA and Europe. Korea shows highest seaweed consumption per capita in the world. The most valuable commercial use of seaweeds is as raw material for extraction of phycocolloids (agar, alginate and carrageenan), which are used in several industries. Seaweeds have been collected from natural stocks or wild populations. In fact, these resources were being depleted by over-harvesting and hence, the need for their cultivation. Today seaweed cultivation techniques are standardised, perfected and made economically favourable. Besides, industry prefers a greater stability through sustained supply of quantity and quality of raw materials. In order to prevent overexploitation of natural seaweed habitats and to meet the needs of industry in an uninterrupted manner, nearly all brown seaweeds, 63 per cent of red seaweeds and 68 per cent of green seaweeds are being cultivated. Top five cultivated seaweeds in the world are Laminaria, Porphyra, Undaria, Eucheuma and Gracilaria. These together account for 5.97 million metric tonnes of seaweed production. Top 10 countries producing seaweeds are China, Korea, Japan, Philippines, Indonesia, Chile, Taiwan, Vietnam, Russia and Italy. The current phycocolloids (seaweed gels) industry stands at over US$ 6.2 billion. The world production of commercial seaweeds has grown by 119 per cent since 1984 and presently, 221 species of seaweeds are utilised commercially including 145 species for food and 110 species for phycocolloid production (Anonymous, 2003). Japan leads the world in the production of agar and consumption. The world most successful seaweed cultivation industries are in Asia. Large-scale seaweed mariculture is only carried out in Asia. Cultivating nori was started in the 1697 in Tokyo Bay and the species is mostly cultivated in Japan. There are many different ways to cultivate seaweed. Cultivating seaweed has been done for a long time and has been cultivated in different ways. Management and conservation of seaweed is needed as seaweed production mostly depending on wild stock. SEAWEED AND THEIR USES Macroscopic marine algae, popularly known as seaweeds, form one of the important living resources of the ocean. It is a source of raw material of alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. It is widely used in both food and non-food industries. Hydrocolloids have attained commercial significance as food additives. The food industry exploits their gelling, water-retention, emulsifying and other physical properties. The applications of alginate find place in frozen foods, pastry fillings, syrups, bakery icings, dry mixes, meringues, frozen desserts, instant puddings, cooked puddings, chiffons, pie and pastry fillings, dessert gels, fabricated foods, salad dressings, meat and flavour sauces. Agar is used in foods such as confectionery, meat and poultry products, desserts and beverages and moulded foods. It is widely used in paper manufacturing, culture media, packaging material, photography, leather industry, plywood manufacturing, preservation of foodstuffs, cosmetics industry and pharmaceutical industry. Carrageenan is also employed in food industry. Its value in the manufacture of sausages, corned beef, meat balls, ham, preparations of poultry and fish, chocolates, dessert gels, ice creams, juice concentrates, marmalade, and sardine sauces. It is also used in the manufacturing of non-food items like beer, air fresheners, textiles, toothpastes, hair shampoos, sanitary napkins, tissues, culture media, and fungicides. Carrageenan is used in salad dressings and sauces, dietetic foods, and as a preservative in meat and fish products, dairy items and baked goods. Figure 1:Carrageenan seaweed It is an alternative to animal-based gelatin in food industries used as enhancer, emulsifier, gelling, thickening, binding and stabilizing agent and also in non- food application such as dentifrice, pharmacology and industrial products. For example, some seaweed polysaccharides are employed in the manufacture of toothpastes, soaps, shampoos, cosmetics, milk, ice creams, meat, processed food, air fresheners and also animal feed, fertilizers for plants and source of various chemicals. In several oriental countries like Japan, China, Korea, etc., seaweeds are a staple part of the diet. In the recent past, seaweeds have also been gaining momentum as new experimental systems for biological research and integrated aquaculture systems. Seaweed products are used in our daily lives in one or the other way. PURPOSES OF SEAWEED MANAGEMENT AND CONSERVATION Management and conservation of seaweeds is needed as seaweed resources are depletion over-time. Seaweed production mostly depending on wild stock and natural stock. Seaweed pollution also a major concern to consider in determine successful of managing coastal environment of the country. Seaweed grows out of control and caused pollutant to birds and marine life and further, leads to death of human when they consume of dangerous marine product. SEAWEED AS USEFUL RESOURCES Figure 2: Application of seaweeds SEAWEED POLLUTION In the coast of Qingdao, East China, a huge blooms of seaweed covering some areas of sea. Local fishermen have been ordered to help clear the carpets of seaweed as it is believe would have to be treated as an obstruction to fishing vessels and other boats. It has resulted in increasing levels of pesticides and fertilizer entering the countrys waterways, providing a food source for the algae. Recent flooding caused by typhoons has also been causes (Anonymous, 2008). Fishing vessels attempt to clear the green algae Workers bag up the seaweeds Seaweed pollution in Qingdao Figure 3: Seaweed pollution 3.2.1 FACTORS CONTRIBUTE TO SEAWEED POLLUTION Seaweed pollution is definition given when seaweeds grow excessively in coastal ocean which may contribute harmful condition on seawater. Seaweeds blooming as a result of industrial, fertilizer and other sources input which run-off into coastal environment. The build-up of seaweeds will increase the photosynthesis and respiration processes which then lead to decomposing of organic matter. The decaying of dead seaweeds will produce hydrogen sulphide, a rotten and toxic gas to marine life and human as well. Factors that may contribute to seaweed pollution in coastal ocean are stated as below: Nitrates as fertilizer sources washed down from local cattle, pig and poultry farms With increasing levels of pesticides and fertilizer entering the countrys waterways, it will providing a food source for the algae to bloom Dumping of industrial waste and heavy metals in run-off areas such as leads and copper Recent flooding caused by typhoons will increase the growth of algae in seawater column And also combined with sunny weather enabled seaweeds build-up 3.2.2 EFFECT OF UNCONTROLLED SEAWEED GROWTH Without proper management, seaweeds growth will cause many problems to environment especially marine lifes. Difficult for vessel and boat passage in ocean water Cut off access to food for local birds, fish and crustaceans Death of marine life with depleted oxygen in the water Further, hydrogen sulphide are produced by the decomposing seaweeds Rotten smell and toxic will leads to death of individual life 4.0 PROBLEMS TOWARDS CONSERVATION OF SEAWEED Unavailability of good quality seedlings Inconsistency of the quality due to adulteration with foreign materials to the seaweed Shortage of raw materials Pollution in conservation areas (industrial waste etc.) Lack of capital to venture into the industry False cultivation method Farmers are strongly urged to stop using raffia string for seaweed cultivation and replace them with nylon strings because using raffia string will affects the quality of carrageenan Diseases affecting seaweeds (ice-ice) Weather inconsistency (flooding, waves) Unavailability of good quality seedlings Lack of capital and RD programmes 5.0 SEAWEED CULTIVATION The cultivation of seaweed, principally for human consumption, is a traditional and still expanding industry in the east, especially in Japan, and increasing interest is being taken in the extension of these practices to other parts of the world for industrial as well as edible purposes. With supplies from certain naturally occurring resources failing to match rising demands and many of the worlds major untapped resources of seaweeds being remotely located, difficult of access or costly to harvest, cultivated raw materials almost certainly will become of increasing significance to processors of both edible and industrial products. Plastic bottles is a method that have been used in Sabah are used to keep seaweed called Euchema Kappaphychus Alverazii afloat. Figure 4: Plastic bottle methods Most seaweeds produce an enormous number of spores and they can be multiplied extensively if culture conditions are perfected. Such conditions depend upon attention to a number of factors. Care needs to be taken with the selection of protected habitats, free from pollution, and of suitable hydrographic environments; the algae need to be protected from predatory fish, sea urchins and other pests and parasites; transplanting of the germlings has to be undertaken with extreme care and harvesting carried out in such a way as to maintain peak productivity. In effect, a full knowledge of the plants biology and reproduction is a fundamental prerequisite to successful seaweed cultivation( Mathieson, 1973). Porphyra The most extensively cultured seaweed is Porphyra, the Japanese nori. Some 60 000 to 70 000 Japanese fisherman are now cultivating nori and producing the dried edible products which are very profitably marketed through a cooperative selling system. Porphyra culture in Japan dates back to the seventeenth century and the earliest cultural practices relied upon the positioning of tree (and later bamboo) twigs to capture the spores. Subsequently, nets became widely used as collecting agents instead of twigs and Conchooelis-phase of the Porphyra life-history. This is a minutely filamentous, shell-boring stage which grows throughout the summer and which can be collected on oyster shells. In the autumn, when the temperature and light levels drop, the conchospores are liberated from the shells and attach themselves to a suitable medium (i.e., the collecting net) to grow into leafy thalli. The nets can thus be artificially seeded in tanks and then transported to the growing areas where they are attached to bamboo poles; about two months after budding the plants grow to between 15 and 20 cm in length and are then harvested. Figure 5:Porphyra sp. These and improved techniques (including freeze-drying of the thalli buds for storage) have resulted in marked increases in yields, in total output of nori and in profitability. Bardach et al. (1972) reported that in some areas up to 750 kg of nori can be obtained per hectare during the six to eight months growing season; the average production value of nori has risen from approximately U.S.$ 870 per ton in 1970 and 1971 to over U.S.$ 1 400 per ton in 1973, suggesting the possibility of gross earnings exceeding U.S.$ 1 000 per hectare. According to Suto (1974) nori farmers earn a net income rate of 60 to 70 percent, making Porphyra cultivation the most profitable of all fisheries in Japan. Undaria The brown alga Undaria or wakame, is also extensively cultured in Japan. Two main systems are used rope cultivation and stone planting. In the former method, strings of synthetic fibre are immersed in seaweed tanks with fertile Undaria weeds in the spring; enormous numbers of spores are released which adhere to the fibre. The fibres are lashed to frames and stored in tanks until late autumn when the young plants, having reached about 1 mm in length, are transferred to rafts in the sea. The wakame grows quickly in the cold winter waters and is harvested when it has reached about 1 m in length. The amount of labour in wakame cultivation is much less than in nori farming; yields of about 10 kg of wet weed per 1 m of cultivating rope can be obtained in northern areas, about a half that yield in warmer districts (Suto, 1974). Where large quantities of Undaria are already growing wild, the planting of large stones or concrete blocks on the sea bottom has been found to help the attachment of the spores and the subsequent growth of the young plants. Figure 6:Undaria sp. Laminaria Increasing amounts of Laminaria, or kombu, are also being cultivated in Japan, using similar stone planting and rope-culture techniques (MacFarlane, 1968). Laminaria culture, however, differs from the other two by the use of dynamite to improve the substrata and control harmful weeds (Wildman, 1974). Propagation of Laminaria has also been long practised in China. Druehl (1972) notes a unique Chinese method of fertilizing Laminaria through the use of porous, elongated earthenware bottles filled with nutrients and seawater which are placed, with young vegetative Laminaria plants, inside a basket-like structure made of bamboo poles and the whole suspended about 1 m below the sea surface. Figure 7:Laminaria sp. Gelidium Some artificial propagation of Gelidium and other agarophytes is practised in Japan but it has not yet been possible to control the release of spores from these species as has been done with many other algae; moreover, the spores take two years to grow and reach harvestable size. Figure 8:Gelidium sp. Eucheuma A high valued species of Eucheuma have been introduced for cultivation or experimental purpose and where commercial quantities are currently being produced for the carrageenan industry such as Fiji, Philippines, USA (Hawaii, California, Florida), Kiribati (Christmas and Tarawa Islands), Tuvalu, Samoa, Malaysia, French Antilles, Tonga, Japan, Indonesia, Federal States of Micronesia, French Polynesia, Guam, China, Maldives, Solomon Islands, Tanzania, India, Cuba, Vietnam, Brazil, Venezuela, Kenya and Madagascar. However, introduction of exotics should not be done indiscriminately as it carries the risk of pathogen invasion, parasites, epiphytes and undesirable changes in the ecosystem. Philippines is largely through the initiatives of one of the worlds largest phycocolloid manufacturers. The practical and economic feasibilities of culturing Eucheuma isiforme species in Florida have been illustrated by Dawes (1974) who considered two proposals, cultivation in natural sites (as in the Central Pacific) and in outdoor tanks. Dawes investigations indicated that tank culture would yield a much higher crop per unit area than mariculture in natural embayments. In the case of field culture, yields in the Florida Keys might average about 20 tons (4 tons dried, clean) Eucheuma per hectare but problems could arise from herbivores, storm damage and admixtures of other weeds; conversely, operating costs should be low. With controlled harvesting in culture tanks, Dawes postulated a potential yield of the equivalent of 243 tons dried, washed material per hectare; net profits, of course, must be considered in the light of tank construction, water movement costs, temperature control expenses, etc. Figure 9:Eucheuma sp. 5.1 SEAWEED CULTIVATION IN MALAYSIA Seaweed cultivation is one of Malaysias fastest growing sectors and is strongly supported by the government. In the 9th Malaysians Development Plan, Sabah was mandated by the government to produce 250,000 metric ton seaweeds yearly by 2010. Currently, the state managed to produce 40,000 to 50,000 metric ton yearly only. Singularly a Sabah product, main commercial species culture is Eucheuma cottonii. Environmental conditions around the Sabah coastline are generally favorable for culture of the species. Many of the operator there are Fillipino ancestry. Seaweed is sold as dried item. It take approximately 9 kg of seaweed to produce a kg of its dried form. Seaweed culture is low capital investment and has a fast turn over. Figure 10:Seaweed Cultivation Project (Semporna) In general according to report by DoF seaweed production still profitable from steady production volume recorded of recent (DoF, 2004a). Seaweed from Sabah is mainly for export market mainly to Denmark . Its dried form is sold directly to exporter without using any middlemen. Usually the later assists farmers by providing its aquaculture facilities hence an obligation to sell the product back. The price for a kg of dried form is about RM1.50. Of late however not many people wanted to get involved in the culture of seaweed because of better opportunities in other sectors. Beside price incentive, commercial production of it is quiet risky as the price is generally fluctuates and harvest largely depend on good sundrying condition. In addition future expend need to take into consideration of conflict with trees passing of fishing boats and promotion of tourism industry. The international market is short of supply due to only up to 30% being produced for the world market. So far, South Korea, Mexico, Philippines, China and Japan are countries producing quality seaweed being ranked 15-30 pts for world market while seaweed produced in Sabah is ranked 30-45 pts. Numerous annual production cycle. From planting till harvesting will take 45 to 60 days only. Thus volume will be substantial. Figure 11:Seaweed cultivation in Malaysia According to Barliotti and Silverthorne (1971), best period to harvest is Aug. to Nov. where agar content of the weed is at its highest, reproduction has already occurred and regeneration is at its maximum value 5.2 REQUIREMENT OF SEAWEED CULTIVATION Choosing a site Find suitable site for cultivating seaweed. A water temperature ranging form 25 Â °C to 30 Â °C is best for growing Eucheuma. Minimum water salinity required is about 28 ppt (parts per thousand) or more. Figure 12: Seaweed should not be planted in front of a river mouth or in fresh water, as fresh water will kill the seaweed. Bottom type A white sandy bottom with the presence of a limited amount of natural seaweed, is probably the best place to cultivate Eucheuma. Eucheuma will not grow very well if the bottom is covered with seagrass because of food competition. A sea bottom with hard coral formations and coral heads also a muddy sea bottom is not a good site to establish farm. BAD GOOD BAD Too many corals Nice clean sandy bottom Too many seaweeds Water movement Moderate water movement is mostly preferred to strong water current. If the water current is too strong, it can damage plants and even wash away planted lines by pulling down the stakes. It will also slow down work as it is difficult work in areas with strong swift current. A constant exchange of ocean water with the changing of the tides and sufficient water movement as the one created by waves is needed. This will bring the necessary nutrients to the plants for a healthy growth. The direction that the water current flows is important for seaweed healthy. Figure 14: Bad water flow: Seaweed farm set against water current. Strong water current can bend or even break the lines. Figure 15:Good water flow: water current flows into the farm Sunlight Clear seawater allows sunlight to penetrate more easily to the plants. Seaweed planted close to the sea surface grows faster and healthier compared to that planted close to the sea bottom or in deep water. GOOD BAD Seaweed planted in shallow water near the surface (30 to 50 centimeters) receives plenty of sunlight and its growth will be good. Seaweed planted in deep water (more than 1 meter from the sea surface) does not get enough sunlight and its growth will be poor. Water depth It is important to consider the water depth while selecting the area of cultivation. At least knee deep water at spring low tide (0.5 meter) is the minimum water depth required to cultivate Eucheuma. In shallower waters seaweed can still grow, but it might be exposed to direct sunlight and wind. As soon as your seaweed is exposed to sun and wind, the tender tips of the plants are destroyed and if exposed for a long time (2 to 3 hours), the whitening of the branches can be seen. This will indicate that part of the seaweed has been killed. Eventually branches will break and drift away from the whitened area. BAD GOOD BAD Too deep at spring low tide Sufficient water depth at spring low tide Too shallow at spring low tide Water pollution Turbid water (muddy) will not sustain good seaweed growth. Chemical pollution will kill the seaweed as in the case of most marine plants and animals. Cultivation methods There are at least 3 methods can use to cultivate seaweed such as Off-bottom (Fixed bottom method), Raft or Floating method and Longline method. Off-bottom Method Wooden stakes are driven into the sea bottom 20 to 25 centimeters apart form each other in straight rows. The stakes should be 5 to 10 centimeter in diameter and 1 or 1.5 meter long. At least 0.5 meter of the stake should be driven into the sand to make them secure. Figure 18:Seaweed line is typically suspended in the Off-bottom Method. A 3 millimeter thick polypropylene rope 5 meters long is firmly stretched between two stakes. Attached to the 3 millimeter rope (line) are 30 pieces of raffia (polypropylene strings). Each of lanting material (seed), the size of the palm of your hand (150 grams), is tied to the raffia strings. The 3 millimeter rope, is suspended at least 20 to 30 centimeters from the sea bottom to prevent the growing seaweed from being tossed on the sand and 20 to 30 centimeters below the water surface at low tide to avoid the seaweeds from being exposed to direct sun light. Direct sun light will kill the exposed parts. The raffia strings, should be 20 centimeter in length with both ends knotted to prevent fraying as shown in the previous photo. The raffia strings are firmly tied to a 3 millimeter rope in such a way that it will not move along the rope as the seaweed grows bigger, or during rough weather. Prepare the lines as quickly as possible and place them in sea water. Seed will grow better if the time of seaweed kept out of the water is limited. Tie the raffia strings to lines on shore before tie seaweed seeds to them. The off-bottom method can be prepare the lines either on shore, in the shallow water at low tide, or in punt near the farm. Raft or Floating Method In the floating method, seaweed is attached to some device that keeps the seaweed floating; rising and falling, with the tidal changes. Seaweed is keep about 50 centimeters below the water surface. The floating devise can be a simple frame made of bamboos, mangrove wood, or bush timber durable in seawater. Tie together four 2.5 meter long bamboos into a square frame and stretch 3 millimeter ropes (lines) inside the frame. In a 2.5 meter square frame, stretch up to 15 lines, 10 to 15 centimeter apart. Each line will carry 15 pieces of seaweed tied to the 3 millimeter rope with raffia. In a frame like the one described, it can plant up to 225 pieces of seaweed. In this method seaweed can be tied on shore by placing the raft on a support (oil drums or wooden posts). Figure 19: Square floating frame built with mangrove wood. The square floating frame, should be anchored to the sea bottom as shown in the figure. As the seaweed starts to grow and become heavier, the frame will sink. To avoid this, be sure to attach to the frame extra bamboos or floaters. Floaters can be simply made of styrofoam or bags filled with unhusked coconuts. Figure 20: A floating frame with additional bamboo to assure sufficient buoyancy. Longline Method The longline method is similar to the raft or floating method in several ways. In fact, seaweed is hung to a rope which is suspended by floaters. In this method, however, the main rope is thicker; about 10 to 15 millimeters in diameter. This rope is tied to plastic floaters or bamboo set at 4 to 5 meters interval and anchored at each end. The pieces of raffia holding the seaweed, can be tied to the main rope in two ways. Figure 21: Simplest way. The raffia string are directly tied to the main rope. Additional pieces of rope, 0.5 to 1 meter long, can be tied to the main line and the raffia strings can be tied to them. Seaweed has to be hung near the water surface to receive sufficient sunlight and can suspend the main line about 0.5 meter below the water surface. As described in the first two methods, the lines can be prepared on shore.

The longline can be damaged by motor-driven boats Handling seaweeds Cover seaweed with tarpaulin or coconut leaves. Use styrofoam boxes to transport your seaweed. In this case, make a few holes on the upper edges of the box to facilitate aeration. Remember to keep the seaweed moist. Do not fill the box with seawater as this will make the seaweed rot rapidly unless the sea water is constantly circulated. Seaweed farmers pouring seawater over a jute bag and a styrofoam box filled with seaweed. Keep the seeds covered to protect them from direct sunlight. Pour some seawater over them at regular intervals. Preparing the lines from your punt, might take several hours and if not covered and kept moist, the seaweed seeds will be spoiled. Disease and predators During December to April, seaweed is more susceptible to diseases and is readily harmed by grazers. Also during this period, the growth of Eucheuma slows down and cyclones and bad weather may cause some damage to your farm. Drying in this period can also be difficult, as it is the wet season in Fiji. As frequently observed, rabbit and puffer fish are the main seaweed grazers. In addition to these, sea urchins and sea turtles are also often seen damaging the seaweed plants. After the warmer months, the rabbit fish grazing becomes a minor problem. In fact, rabbit fish move away from the seaweed. It is always a good idea to set your farm far away from coral heads, since these fishes normally live around the corals and move out to graze on seaweed. Do not leave rubbish (tins, unused stakes, bits of wood, etc.) as these make a very good home for rabbit fish. Whitened areas are more exposed to fungal infection. Especially during the warmer months, fungal infection can spread quite rapidly and the seaweed plants show large portions of discolored branches commonly seen as white and pink areas. Ice Ice is the common term used to describe seaweed plants in this condition. Weather Apart from occasional bad weather (rough sea and heavy rain), the effect of cyclones occurring during the summer months can be devastating. If a cyclone season is expected, harvest as much seaweed as you can and keep it on shore protected from wind and rain. Put aside sufficient seaweed to allow you to re-start farming after the cyclone has passed by. Remember to keep this seaweed in bags moist with seawater at all times. That seaweed will be your re-planting material. If seaweed is kept small during this period, and not allowed to become over-mature, little damage is expected. Decide to harvest after 4 or 5 weeks of growth instead of waiting for 6 or 8 weeks. Experience after going through several cyclones suggest that this strategy could limit your damage. Also, be sure that stakes are firmly erected otherwise the strong water currents and swells during cyclones might wash away your effort. After the cyclone has gone through, tangled lines should be entangled and secured again. Badly damaged seaweed should be completely removed and replaced with new seeds. 6.0 MANAGEMENT AND CONSERVATION OF SEAWEEDS In the case of already heavily exploited resources, future potential has also to be considered in the light of the growing need, in some important cases, for management and protection. Some commentators (including Stanford, the discoverer of algin acid, as lo

Analgesics :: essays research papers

Analgesics "An aspirin a day keeps the doctor away." Although this saying can be true, it is not only aspirin that can cure the pains of life, but also several other types of analgesics. There are a wide variety of analgesics. More commonly known as painkillers. The narcotic analgesics act on the central nervous system and change the user's perception; they are more often used for severe pain and can make the user develop an addiction. The nonnarcotic analgesics, known as over the counter or OTC, work at the site of the pain. These do not create tolerance or dependence and do not vary the user's perception. OTC's are more commonly used everyday to treat mild pain. Many people wish to treat familiar pains themselves, such as toothache or headache pain. To treat these types of symptoms, OTC's are used. There are three main types of OTC drugs. They are as follows: Â ·Aspirin (salicylic acid acetate) is an anti-inflammatory (decreases swelling and inflammation), anti-pyretic (fever reducing), and anti-platelet (decreases platelets in the body to thin blood). Many heart treatment patients take an aspirin a day to prevent blood clotting. However, if aspirin is taken in large quantities over long periods of time, it may cause gastric ulcers or other internal damage. The molecular formula of aspirin is C9H8O4. Some examples of Aspirin are Bayer, Ecotrin, and Aspergum. Â ·Ibuprofen (propionic acid) is an anti-inflammatory and anti-pyretic. It is often used to treat arthritis, dental pain, menstrual pain, headache, migraine, and back pain. Ibuprofen works by reducing the levels of prostaglandis (substances that cause pain) in the body. This drug is gentler on the stomach than aspirin. The molecular formula of ibuprofen is C13H18O2. Some examples of ibuprofen are Motrin, Advil, and Nuprin. Â ·Acetaminophen (Paracetamol) is an alternative to aspirin. It is also an anti-inflammatory, anti-pyretic, and anti-platelet. Acetaminophen is much less likely to cause intestinal side affects than aspirin, however overdose of this drug can cause serious liver poisoning. The molecular formula for acetaminophen is C8H9NO2. Some examples of Acetaminophen are Tylenol, Midol, and Panadol. Each of these OTC analgesics has different side affects and purposes, but they all share three common elements. These elements are Carbon (atomic number 6, atomic mass 12.011), Hydrogen (atomic number 1, atomic mass 1.0079) and Oxygen (atomic number 8, atomic mass 15.999). By looking at the molecular formulas of each type of OTC analgesic, these three common elements form the base for each chemical compound.

Any children who are â€Å"fussy eaters† are encouraged to sit with their friends and try things that their friends are eating. We are always on the lookout for children with food phobias or if any child never wants to have a snack so that we can speak with their parent/carer to ensure that they are able to seek further guidance if required. If we ever have food that would not be considered â€Å"healthy† such as cake, biscuits, ice-lollies, it is always very clearly stated that the children are having a special treat that day and the children are always encouraged to play an active ga me (outside if possible).

Art of Graffiti Essay Example | Topics and Well Written Essays - 1000 words

Art of Graffiti - Essay Example . . . To them to get busted is like a Purple Heart. Nobody really slams the doors on those thugs. These graffiti vandals are causing people pain and grief. They think they're artists and have some right like free speech to express their individualism or artistry. If they want to be an artist they should go to work for a record company and do hip-hop CD covers. Graffiti might look good to them and their buddies, but the majority of the people don't want to look at that crap every day"2. As a matter of fact "any type of cultural or artistic production forces change on an environment. Most of the time, people abide by well-established rules for culture-producing activities. They do it through consuming certain products in certain ways or by creating symbols of their identity within the scope of what is legal for the entire society. In general, people who write graffiti produce culture in a different manner. No matter what it says, the manner in which graffiti is produced defines the writer's position as an outsider and alienates that person from the rest of society"3. Although there are hundreds of individual styles of graffiti, there are only seven basic forms in which it appears. These forms, the names of which are known to all graffiti writers, can be distinguished generally by their size, location, complexity of design, or the materials used to create them4. Bubble is a style, in which all similar to each other letters are rounded, joined with each other, and looks as though exaggerated, similar to bubbles bursting at the seams. More often it is used just few colors, basically two or three. This is one of the most popular styles of beginners. Wild Style differs from all the other styles, first of all, by the complexity of letters, which most often are non readable. They are so mazy that sometimes even people who know what's what in graffiti and write it, are not capable to puzzle out an inscription, let alone everymen. And only those, who draw in such style, without can easily read the text of the image. The point is that a writer adds additional elements to the letters, which distract attention from letters.FX (or 3D style) differs in absolute volume of letters. To think up such figure is very difficult. It is necessary to possess not ordinary imagination and uncommon thinking to draw a word in volume. Thus, it is necessary that all letters were combined with each other, and it was clear enough what is written. Far not every writer is capable to do it. Moreover a writer needs many years of trainings to write graffiti in this style.Messiah Style.

Friedrich Nietzsche a Philosopher in Society Essay

Friedrich Nietzsche a Philosopher in Society - Essay Example This essay analyzes that nationalism is the belief that groups of people are bound together by territorial, cultural and (sometimes) ethnic links (Glossary, online). Capitalism is an economic system in which the production and distribution of goods depend on invested private capital and profit-making. Politically, this means the dominance of private owners of capital and production for profit. By extension, 'capitalism' has also taken in the belief that government should have nothing to do with the economy (Glossary, online). Capitalism is a form of government for a nation state, or for an organization in which all the citizens have a vote or voice in shaping policy (Democracy, online). Socialism is a political and economic theory of social organization that advocates that the community as a whole should own and control the means of production (Glossary, online). Conservatism is a political philosophy or attitude that emphasizes respect for traditional institutions, distrust of gover nment activism and opposition to sudden change in the established order (Glossary, online). Liberalism is a term that gained significance in the 19th century when it meant the limiting of government power and the increase of social reform (Glossary, online). ... All Too Human, Daybreak, The Gay Science, Thus Spoke Zarathustra, Beyond Good and Evil, On the Genealogy of Morals, The Case of Wagner, The Twilight of the Idols, The Antichrist, Ecce Homo, Nietzsche Contra Wagner, and The Will to Power (Friedrich Nietzsche a, online). Friedrich Nietzsche is famous for his rejection of Christianity (Friedrich Nietzsche b, online). He described Christianity as a nihilistic religion because it evaded the challenge of finding meaning in earthly life, creating instead a spiritual projection where mortality and suffering were removed instead of transcended. He believed nihilism resulted from the "death of God", and insisted that it was something to be overcome, by returning meaning to a monistic reality. He sought instead a "pragmatic idealism," in contrast to the prominent influence of Schopenhauer's "cosmic idealism" (Nihilism, online). He is also famous for his idea of "will to power". Hopes for a higher state of being after death are explained as compensations for failures in this life. The famous view about the "death of God" resulted from his observations of the movement from traditional beliefs to a trust of science and commerce. Nietzsche dissected Christianity and Socialism as faiths of the "little men," where excuses for weakness paraded as moral principles. John Stuart Mill's liberal democratic humanism was a target for scorn, and he called Mill "that blockhead" (Friedrich Nietzsche b, online).
