Project Management For Project Managment - 2025 Words

As the world is chaotic (Djavanshir and Khorramshahgol, 2006) it is impossible to always predict the future accurately. Teller at al (2012) describes project management as balancing the â€Å"iron triangle†, where changes to any one of the planned costs, quality or scope will change the other elements. Risk management allows contingency to be put into project plans, (APM, 2012) minimising negative effects and maximising the benefits of uncertainty. This, in theory, is how project risk management aids in ensuring successful project delivery. The Association for Project Managment (APM) defines a project risk management in the following statement: â€Å"All projects, programmes and portfolios are inherently risky because they are unique, constrained,†¦show more content†¦Improvements are often possible, even when a project is to cost, quality and scope. (Shahu et al, 2012) This would be hard to prove, as repeated experimentation is rare due to the difficulty in creating exactly the same environment more than once. So a large-scale study would be needed. Until such a study has taken place, it is safe to assume that if project risk management brings benefits to projects, it would bring extra benefits to successful projects. (Shahu et al, 2012) This would be by being able to exploit and mitigate risks, issues and opportunities early, as well as increasing the accuracy of predictions which assist decision making. Even in these chaotic business environments, portfolios can still be managed effectively. In aggregate, having more projects and risks make a business’s forecasts more likely to include the actual project costs, (Djavanshir and Khorramshahgol, 2006) although the range of possibilities given will be wider. Statistically, when more projects are in a business’s portfolio, this means that the projects balance each other out, making the investments safer, as it is highly unlikely for them all to fail. (Djavanshir and Khorramshahgol, 2006) This can also be seen at a more detailed level in project risk management during Monte Carlo analysis (MCA).

Hockey Observation Report Free Essays

string(31) " had hit London boys one shot\." Yesterday was the first time bought a ticket to watch a live game of junior hockey. I sat behind the net of Pets for two periods and watched the game. That’s a great place to see if London boys are going to shoot the puck into the net or not, but also, it’s hard to look at the left way of the rink to follow the game. We will write a custom essay sample on Hockey Observation Report or any similar topic only for you Order Now It was a great time, and it is much better than watching on TV or internet. I can really fell the atmosphere at the stadium and enjoy the game. That was the game that people expected London Knights will get the ten-game winning streak, but London boys were lost before over 9,000 fans at Budweiser Gardens. Subculture Members Senior was the largest group of audiences in Budweiser Gardens. You probably could see them everywhere, and they also are one of biggest fans of London Knights. It’s easy to recognize them by their outlooks, drinks they had (mostly were beer for men), clothes (they dressed London Knight Jerseys with old design, not the new one). They have huge knowledge not only about Indo Knights hockey, but also about other subcultures of hockey: women hockey, NIL, Olympic hockey†¦ Junior and minor also are big parts of fans. They normally had a group of friends and watched the game together. They wore hoodoos or hockey jerseys with jeans and sneakers. You could hear them talk about the game and players that they adore not only London Knights but also other teams from NIL such as Toronto Maple Leaf, Detroit Red wings, Winnipeg Jets Young adults came to the game alone or with their friends. They drank beers, and their outlooks are different with: Jeans, shirts or T-shirts, caps†¦ Beside the topic about London hockey, they also talked about NIL, works, loves, lives†¦ Its not hard to define them with other groups. Families came to the game with their children. They talked to kids bout hockey, players, the rinks, the puck†¦ I believe that a passion Of a kid was developed by their parents, especially their fathers. Kids and then Will become a big fan of hockey and could be a good player too. Beliefs and Values At the last two minutes, after the coach of London decided not to put the goalie on the rink to protect the net after they got the first shot, but another player, Petrography got the chance to shoot the third score in the net of team London. A lot of audiences felt angry and disappointed; they screamed loud. They stood up and left their seats to go home because they believed hat London would lose because no more chances for London to get 3 shots into the net of Petrography to win the game, and finally, Knights’ boys were lost. When one player of Petrography had to get in the penalty box and London Knights had a good chance to score, all of audiences that Loon’s fans started standing up and chanting: â€Å"Go, Knights go! Go Knights go! † to cheers for the boys because fans believed that London could get one shot for that big chance. They were absolutely right; London boys slapped grateful shot into the net with all hard try. The scaffold was blow upped by those screams of London fans. Customs and Behaviors Before the game began, everyone stood up and Sang the song â€Å"O Canada†. Almost everybody just stood up and listened to children’s choir sing the song, but the man who stood behind me sang it out loud. I could feel that Hess so proud of Canada and also respect to it and all other people. A fan sat right behind the net of Pets punched on the protected glass when London boys missed their shots so many times. He punched and screamed loud: â€Å"Shoot that puck into the net† to show his anger on the boys and the way they played. At the corners of the rink, players of both Pets and London usually push heir rivals into the bar to make them cannot move and get hurt. Therefore, players could create chances to get the puck or help their team mates get the puck to score or protect their goal. Loon’s goalie normally went out a little too far from the goal and he stood more on the left of the net. That created chances for Pets boys to get two scores into Loon’s net. Lineup is a normal thing but it shows people’s behaviors. Audiences waited on the line to get into the arena and also to get out during the break time. People just usually line up to buy foods, tickets†¦ ND other things else, but inning up to go washroom and waiting for quite long time is really polite and culturally. It shows people’s good ethics and behaviors. It’s absolutely right to say that Canadians are very polite. A London boy broke his stick while he was trying to get the stick from a Pets boy. Then he dec ided not to care about the stick but moving follow Pets boy to hinder him pass the puck to his team mates. He also tried to get another stick from the other boys when he got a chance. My seat is not the best place to follow all over the rink because it’s hard to see what’s happening on the left corners at our seats. Teases why every time suck was passed to that place, people normally tried to leaned and moves their body up a bit, so they could watch the game easily; therefore they would not miss if London boys score. Clapping your hands to make applause for your home team is normal thing, but when it’s done for Loon’s competitor- Pets is a different story. A man that is London Knights’ fan, who sat beside my section made applause for Pets boys after they had hit London boys one shot. You read "Hockey Observation Report" in category "Observation essays" In my opinion, that was really great shot from the left side of the net, and it should be appreciated not only by Pets fans, but also other people that are not. Almost everyone stood up, clapped their hands, and screamed loud right after London boys got one shoot into Pets’ net. That’s the way people cheer up for their boys and show their excitations. They kept doing it for a while until the game started again. The referees normally did not move after they dropped the puck until boys get it or shot it far away from him. They do not want their movements affect to the puck; therefore, players could easily to follow and throw or pass it to their team mates. Social Relationships Few parents came to watch their sons play on the game. They came to enjoy he game and cheer not only for their boys, but also the others too. Taking pictures could not be forgotten because they want to capture the moments that their sons were skating, playing and enjoyed the game. Couple groups of minor players’ sibling socializing cam to watch the game of London Knights. They could enjoy watching their favorite sport, but also that could be an example for them to learn how to play, what can be happened, how they can solve problems†¦ They sat together, talked to each other, and commented about the game. A few couples of husband and wife came to watch the game as the way to relax on the weekend. They sat beside each other, shared foods and drinks†¦ During the second break, kiss cam moved around to catch people’s kisses and ask people to make kisses. It was wrong for few times when it mixed up two couples and made people laughing. A group of Pets fans came to Budweiser Gardens to support their boys. They sat together and talked about both London and Pets, how they play, about London†¦ They were very happy when Pets beat London boys with ratio 3-1. Some journalists also were there to watch the game and also record about it for London local newspapers. Hind that they watch it more carefully than there people because that they have to write a report later to provide the information about the game for people who did not came to. Institutions and Organizations When got into the gate, saw few groups of minor hockey organization was selling 50-50 tickets for their upcoming game next week. If you buy a ticket at Budweiser Gardens that was sold by minor hockey organiz ation, you just need to pay half of price (it was around 10 bucks), and a lot of people like junior, parents purchased couple tickets for themselves and their kids to enjoy the game while support for minor hockey organization. Aluminum Associates sold stuffs of London Knights team such as: hats, stickers, pucks, jerseys†¦ That are provided to Loon’s fans. They get involve with Budweiser Gardens to sell things while supporting for London boys and also bring revenue to run the team. Banshee College sold ticket of the game for Banshee students with price that under regular price to bring students to the game. They work with Budweiser to get tickets for students with cheaper price. You probably could see a lot of Banshee students with their tickets that was purchased at Biz Booth. Material Goods Since I got into the Budweiser Gardens, could see a lot of people wear Indo Knights’ jerseys: kids, men, and women, senior†¦ Not only that, they also dressed Knights’ hats and scarf. Everything made a wonderful picture of white, yellow and green. A lot of people ate pizza of Pizza Pizza while they were watching the game. During the brake time, the line of people waiting for pizza at Pizza Pizza store was as long as other stores’. Pepsi is favorite drink for kids during the game. They also grabbed few bags Of popcorn to get ready for the show. For adult men, they bought a cups or bottle of beer like Bud Light or Budweiser with French fried from Harvey’s or other brands. In the second breaking time, London Toyota Company showed audiences their two brand new cars for 2014. Everyone kept talking about it for a while until the game start the third period. After the breaks, two girls sat beside me came back with a bag of Lays’ chip and a Harvey’s’ burger. I saw some women and kids wore yellow and green cheer gloves, the main colors of London Knights. There was a kid sat in front of me with a small hockey stick with London Knights’ sticker on his hand since the game starts until the end. Language I probably have to say that the man sat beside me during the game is one of the craziest fans Of London Knights. He screamed out loud at the guy of Pets, who put a guy of London team on the rink: â€Å"Shut the f*** up Devils! † He looked very serious and tried to protect the player of the team he likes. â€Å"Go, Knights go! Go, Knights go! † was chanted to cheer up the spirits of players by audiences (kids and seniors almost) when they have good chance to attack and score. The sound kept going around and around with the applause, the sound of the bell from a woman, and the vaguely trumpet. It made both audiences and players feel exciting and happy. Some other young guys from the section beside me got mad when the game almost finished. When London players shot the puck out of the net of Petrography, they screamed: â€Å"That net must have a big hole! † Fans got really angry because London boys missed too many chance to get the puck into the net. When the game almost finished, referees decided to put both players Of Petrography and London into the penalty box because they got fight. The Petrography player yelled at referee: ‘What the h***? Why do I need to go there? ND continued fighting with the boy of London. Both of them finally were eliminated out of the rink. The two boys sat at the 2 lines in front of me attracted me while the discussed about the game and players: â€Å"He should shoot it immediately when he was close to the net, not waiting for others†¦ † They talked about it with a wonderful passion, and they are in live with the game. Il l. Conclusion Attending the game was the great time to relax for the weekend and finish my reading week, but got a bit disappointed because London boys were defeated 3-1 by Petrography Pets. Anyway, enjoyed the game, mingled tit the crowd, and were a part of the game like other London Knights fans. It was a good chance for parents to bring the hockey passion to their kids while showing their passions also. Junior hockey in London is great subculture for everyone who loves Hockey. It is not only the key to help junior players to become a professional hockey player, but also, it is the game for people to show their loves to hockey and Loon’s team. In addition, London is a door for kids to see that hockey is an important passion of their lives. You cannot have the felling how London fans get crazy until you are a part Of it.

Geothermal Energy Essay Conclusion Example For Students

Geothermal Energy Essay Conclusion Geothermal EnergyMatt Arnold9/17/96Physics 009Professor ArnsThe human population is currently using up its fossil fuel supplies atstaggering rates. Before long we will be forced to turn somewhere else forenergy. There are many possibilities such as hydroelectric energy, nuclearenergy, wind energy, solar energy and geothermal energy to name a few. Each oneof these choices has its pros and cons. Hydroelectric power tends to upset theecosystems in rivers and lakes. It affects the fish and wild life population. Nuclear energy is a very controversial subject. Although it produces highquantities of power with relative efficiency, it is very hard to dispose of thewaste. While wind and solar power have no waste products, they require enormousamounts of land to produce any large amounts of energy. I believe thatgeothermal energy may be an alternative source of energy in the future. Thereare many things that we must take into consideration before geothermal energycan be a possibility for a human resource. I will be discussing some of theseissues, questions, and problems. In the beginning when the solar system was young, the earth was stillforming, things were very different. A great mass of elements swirled around adense core in the middle. As time went on the accumulation elements withsimilar physical properties into hot bodies caused a slow formation of acrystalline barrier around the denser core. Hot bodies consisting of iron wereattracted to the core with greater force because they were more dense. Thesehot bodies sunk into and became part of the constantly growing core. Less denseelements were pushed towards the surface and began to form the crust. The earlycrust or crystalline barrier consisted of ultra basic, basic, calc-alkaline, andgranite. The early crust was very thin because the core was extremely hot. Itis estimated that the mantel e 200 to 300 degrees Celsius warmer than it istoday. As the core cooled through volcanism the crust became thicker and cooler. The earth is made up of four basic layers, the inner solid core, the outerliquid core, the mantel and the lithosphere and crust. The density of thelayers gets greater the closer to the center of the earth that one gets. Theinner core is approximately 16% of the planets volume. It is made up of ironand nickel compounds. Nobody knows for sure but the outer core is thought toconsist of sulfur, iron, phosphorus, carbon and nitrogen, and silicon. Themantel is said to be made of metasilicate and perovskite. The continental crustconsists of igneous and sedimentary rocks. The oceanic crust consists of thesame with a substantial layer of sediments above the rock. The crust covers the outer ridged layer of the earth called thelithosphere. The lithosphere is divided into seven main continental plates. These continental plates are constantly moving on a viscous base. The viscosityof this base is a function of the temperature. The study of shiftingcontinental plates is called Plate Tectonics. Plate Tectonics allows scientiststo locate regions of geothermal heat emission. Shifting continental platescause weak spots or gaps between plates where geothermal heat is more likely toseep through the crust. These gaps are called Subduction Zones. Heat emissionfrom subduction zones can take many forms, such as volcanoes, geysers and hotsprings. When lateral plate movement induced gaps occur between plates,collisions occur between other plates. This results in partial platedestruction. This causes mass amounts of heat to be produced due to frictionalforces and the rise of magma from the mantle through propagating lithospherefractures and thermal plumes sometimes resulting in volcanism. During platemovement, continental plates are constantly being consumed and produced changingplate boundaries. When collisions between plates occur, the crust is pushed upsometimes forming ranges of mountains. This is the way that most Midoceanicranges were formed. Continental plates sometimes move at rates of severalcentimeters per year.Currently the Atlantic ocean is growing and the Pacificocean is shrinking due to continental plate movement. In Rome people first used geothermal resources to heat public bathhouses that were used for bathing or balneology.The mineral water was thoughtto be therapeutic. The minerals in the water have been used since the beginningof time. Through out the years geothermal heated water or steam has been usedin many different systems from heating houses and baths to being a source ofboric acids and salts. Today geothermal fluids provide energy for electricityproduction and mechanical work. Boric acid is still extracted and sold. Otherbyproducts of geothermal heated liquid are carbon dioxide, potassium salts, andsilica. The first 250 kilowatt geothermal power plant began operation in 1913 inItaly. By 1923 the United States had drilled its first geothermal wells inCalifornia. In 1925 Japan built a 1 kilowatt experimental power plant. Thefirst power plants constructed in Italy were destroyed in WWII, then rebuiltbigger and more efficient. Mexico built a 3.5 megawatt unit in 1959. In theUnited Stat es an 11 megawatt system at the geysers in California was constructedin 1960. Japan then installed a 22 megawatt plant in 1966. Geothermal energyhas been used for things other than energy production, such as geothermal space-heating systems, horticulture, aquaculture, animal husbandry, soil heating andthe first industrial operation of paper mills in New Zealand. Large scalegeothermal space-heating systems were constructed in Iceland in 1930. The word geothermal, refers to the thermal energy of the planetaryinterior and it is usually associated with the concept of systems in which thereis a large reservoir of heat to comprise energy sources.Geothermal systemsare classified and defined depending on their geological, hydrogelogical andheat transfer characteristics. Most geothermal heat is trapped or stored inrocks. A liquid or gas is usually required to transfer the heat from the rocks. Heat is transferred in three different ways, convection, conduction, andradiation. Conduction is the transfer of energy from one substance to another,through a body that may be solid. Convection is the transfer of energy from onesubstance to another through a working moving medium, such as water. The mediumusually transfers the energy in an upward direction. Radiation is the transferof energy out of a substance through the excitement of gas molecules surroundinga substance. Radiation is dependent upon two things the object emitting theheat and the surroundings ability to absorb heat.Convective geothermalsystems are characterized by the natural circulation of a working fluid or water. The heated water tends to rise and the cool to sink continually circulatingwater throughout the ground. The majority of the heat transfer is done throughconvection and conduction, radiation hardly ever effects heat flow. Whengeothermal heated water collects into a reservoir one form of a geothermalresource is created. One can approximate the amount of thermal energy presentin a geothermal resource by comparing the average heat content of the surfacerocks with the enthalpy of saturated steam.Enthalpy is energy in the form ofheat released during a specific reaction or the energy contained in a systemwith certain volume under certain pressure. It is generally accepted that belowa depth of ten meters, the temperature of the ground increases one degreeCelsius for every thirty or forty meters.At a depth of ten meters annualtemperature changes no longer affect the temperature or the earth. The most common geothermal resources used for the production of humanconsumed energy are hydrothermal. Hydrothermal systems are characterized byhigh permeability by liquids. There are two basic types of hydrothermal systems,vapor and liquid dominated systems. In a liquid based system, pumps must beplaced very deep in the well where only the liquid phase is present. By keepingthe liquid under pressure it is possible to keep the liquid at a much highertemperature than the liquids normal boiling point. If the liquid is not keptunder pressure, it will flash. Flashing is the process of vaporization. Itrequires 540 calories per gram of heat to vaporize water. The super heatedpressurized water is pumped up a long shaft into the plant. When it reaches theplant, controlled amounts of the pressurized water is allowed to flash orvaporize. The rapidly expanding gas pushes or turns the turbine. A power plantmay have numerous flash cycles and turbines. The more flash cycles the higherthe efficienc y of the power plant. Once the heated liquid has been used to thepoint where it has cooled to an unusable temperature it is reinjected into theground in hopes that it will replenish the geothermal well. Vapor systems workin much of the same way. The super heated gas flows through surface reboilersthat remove all of the non-condensable gases from the mixture of gases. The gasis pumped into pressurization tanks where extreme pressure causes the gas tocondense.The super heated liquid is then allowed to flash. The rapidlyexpanding gas turns the turbine. Specific examples and sites of electricalenergy production will be discussed later. Conductive geothermal systems consistof heat being transferred through rocks and eventually being transmitted to thesurface. The amount of heat transferred in a conductive geothermal isconsiderably less than the heat transferred in a convective system. Conductivegeothermal systems lack the water to efficiently transfer the heat, so watermust be artificial ly injected around the hot rocks.The heated water is thenpumped from the underground reservoir to the surface. This system is not aseffective as others because the temperature that the heated water reaches is notvery great. Geopressured geothermal systems are similar to hydrothermalsystems. The only difference is the pressure of the high temperature reservoir. Prostitution Through the Functionalism EssayThe earth around the Geysers geothermal site consists of highly permeablefractured shales and basalts created during Jurassic age. The ground abovethe wells consists of graywake sandstone. This form of sand stone is very hardto penetrated. Scientists believe that the large geothermal reservoir wascreated when an earthquake caused fault and shear zones. Steam temperatures inthe geothermal wells range from 260 to 290 . Pressures deep in the wells rangefrom 450psig to 480psig (3.1MPa to 3.3) . Some wells are 3000 meters deep andproduce almost 175 tonnes of steam per hour. It is thought that the center of the magma or the heat source at TheGeysers geothermal site lies under Mt. Hannah. Geologists are led to believethat there is a large mass of magma cooling under the geysers and power plantsthat is the source of all the heat.This assumption is proven when seismicwaves caused by earth quakes are slowed when they pass through the mountain. Afairly large fractured steam reservoir rests above the cooling molten. In 1967, the Union Oil Company in partnership with Magma PowerCorporation and Thermal Power Company began producing electricity from theGeysers Geothermal region and selling it to the Pacific Gas and Electric Company. The turbines in the power plant were designed to operate under intake pressuresof 80psig to 100psig.At first the plant operated at maximum efficiency but asthe years went by the geothermal resource was slowly depleted. The depletedheat source did not produce the constant pressure that was required for maximumefficiency so the efficiency decreased. There are two methods of drilling wells,mud drilling and air drilling. Mud drilling tends to clog up the porous rockbut it is easier on the drilling machinery.Air drilling leaves the porousrock free for water and steam flow but it is very hard on machinery due toabrasion and heating.Air drilling is therefore very expensive. Geothermalwells do not always maintain constant pressure. New wells must be drilled tocontinually maintain constant pressure on the turbine. The system built at TheGeysers geothermal field deliversof super heated steam. The steam producedby the wells is not pure water but consists of 1% non-condensable gases alongwith du st particles.If not cleaned off, the dust can accumulate on the insideof the turbine blade shrouds and cause turbine failure. This problem wasvirtually eliminated when heavy duty blades and shrouds replaced the faulty ones. It was thought that by the time the steam made it to the turbine very little ofit was still superheated, so special non-corrosive metal was not required in theconstruction of the upper level piping and the turbine. Normal carbon pipingwas used in the original construction. This proved not to be the case, after awhile the pipes began to corrode. As steam condenses non-condensable gasesbecome more of a problem. They become more concentrated, more corrosive and canform sulfuric acid.This new problem was solved by replacing the carbon steelused in the original construction with austenitic stainless steel. Electricalconnections and wires were also effected by concentrations of sulfuric acid. They were replaced with aluminum and stainless steel. The steam generated from the wells and geysers has a constant enthalpyof 1200-1500 Btu per lb.The use of condensing steam turbines that exhaustedwaste water below atmospheric pressure increased the efficiency of the plant. There were no rivers or streams in the immediate area that were sufficientlycool enough to be used as a cooling mechanism, so cooling towers wereconstructed. Incorporating the cooling towers into the system allowed the wastewater to be discharged at a cooler temperature f 18 therefore increasing thepossible efficiency of the system. Carnot Efficiency of The Geysers Power PlantCarnot Efficiency ==18=290Carnot Efficiency =Carnot Efficiency = .4831or48%This is a relatively efficient cycle. It certainly can compete withother modern day types of electricity production. Unfortunately carnotefficiencies can never be reached. A large amount of energy is lost in thecondensers and turbines. I feel that while the efficiency of this geothermalpower plant might not be overwhelmingly better than other modern day methods ofelectricity, the lack of pollution makes up for the loss in efficiency. Eventhough The Geysers power plant is relatively efficient, it does not even comeclose to taking advantage of all the emitted heat. Only 2% of the emitted heatfrom the source is used to heat water for electricity production.Thisgeothermal resource will not last for ever though. Heat Content of the EntireGeysers Geothermal Site-The Geysers geothermal site covers approximately . -Heat is onlyrecovered from the top 2km of the earth at The Geysers site. -The average temperature in this top 2km of earth is 240 . -The average air temp at The Geysers site is 15 . -The specific heat ofthe permeable rock that makes up most of geothermal region is . Volume xSpecific Heat x Change in Temperature = Heat ContentVol = x = SpHt== 240 18 = 222Q =( x )( )( )(222 )Q= Joules of Heat Content in the entire Geysers geothermal regionLife of The Geysers Heat Source -Power output of The Geysers plant =2000MW Fraction of the total heat used in the production of steam = 2%-Power taken from the geothermal resource = 2,000MW/2% = 100,000 MW -Heat content of the entire Geysers geothermal region =Joules -Seconds in one year = -1 Watt = 1 Joule/sec 100000MW = J/yearJ/ J/year = 24.67years. According to my calculations The Geysers geothermalresource will be depleted in 24.67 years at the current rate of usage. Ofcourse this is not taking into account the rate at which the resource is renewedfrom heat coming from deeper in the earth. I am assuming that the rate ofdepletion is so much greater than the rate of renewal tha t it is not significantin the calculation. The power plant at The Geysers site is run on dry superheated gases. The power plant now has 11 generators and has a rating of over 2000 MWe.Theprocess of electrical power generation used at The Geysers power plant isrelatively simple when compared to other modern day power plants. The steamthat evolves from the wells flows through pipes that lead to the turbine. Thepressure exerted by the superheated steam turns the turbine which produceselectricity. The steam then flows into the direct-contact condensers below theturbine. Cooling water from the cooling towers is constantly circulated throughthe condensers. The condensed steam and cooling water is then pumped back intothe cooling towers. Because the evaporation rate from the towers is slower thanthe rate at which water is pumped into the towers, excess amounts of wateraccumulate in the cooling tower. This excess water is then pumped toreinjection wells where it flows down through the soil and porous rock and isreheated by the heat source. The cycle begins all over again. See the diagrambelow. The costs of running this particular geothermal electrical plant are verycompetitive with the cost of other types of modern day plants. The operationcosts for the plant at The Geysers is almost same the as the operation costs ofan average fossil fuel powered plant and much less than the operating costs of ahydroelectric or nuclear plant. One of the greatest advantages of this and mostgeothermal systems is the relative lack of pollution. While most coal plantsgive off significant amounts of sulfur, somewhere around 93 tons per day for theaverage coal plant, geothermal plants produce no gas pollution other than thegases that would be naturally emitted from the geysers anyway.Coal plants areby far the worst polluters but other types of plants are not far behind.

There have beenmany technological breakthroughs that have resulted in increased efficiencies ofmodern day geothermal electrical plants. I feel that with the currentenvironmental situation that the world now faces a viable method of clean upwill include the use of geothermal power plants and resources. In a world thatis suffocating from the chemicals, and particulates that are created in theproduction of electricity and other commercial indu stries, we have no choice butto change our ways. The earth can not support the current rates of pollution. If we do not change reduce pollution the effects that are beginning to be seenow will become irreversible. Using geothermal resources for other purposes suchas space heating can only help reduce pollution emission. With in the nextcentury the world will begin to feel the energy crunch. Supplies of othernatural resources such as coal, oil and other petroleum products will begin tobecome scarce. The world today is completely electricity dependent. Withoutelectricity, the world as we know it would cease to exist. In the next centurywe must learn to be less electricity dependent or find other sources of energy. If less env

Animorphs Essays - Fiction, Literature, Speculative Fiction

Animorphs One of my favorite books is Animorphs#7 The Stranger. It's about five kids who have the power to morph. In other words they can change into any animal they touch. By touch I mean they absorb a strand of the animal's DNA. Then, from the DNA, they are able to create an exact copy of the animal and take on the copy. They can change into any animal they touch. There is a series of these books. In this book they find an entrance to a Yeerk pool, a necessity of their alien enemies, the Yeerks. Once inside they creep around, as roaches, to see if they can pick up any information about the location of the Yeerks' Kandrona, a portable version of the Yeerks' home sun, which is also a necessity, so they can destroy it. However they don't count on being a Taxxon delicacy. The Taxxons are allies of the Yeerks. Just as the Animorphs, Jake, Rachel, Marco, Cassie, and their alien friend Ax, are about to be devoured, time itself stops, except for the Animorphs. Then they meet an Ellimist, a creature who is woven into time and space itself, who stopped time to ask the Animorphs to decide the fate of the human race. They can either go to another planet and leave Earth to the Yeerks or they can stay and fight. When the decision to stay is made the Ellimist puts them back on the Taxxon's tongue. Somehow, they manage to get out of the Yeerk pool in one piece. A couple days later, they meet in the woods around Cassie's house and are having conversation about reconsidering the Ellimist's offer. Suddenly they are zapped into a possible future. There they walk and look around freely, since everyone is a Controller, a creature controlled by a Yeerk. See Yeerks are parasites. They infest a creature's brain and take over its body. The creature is still there, but it can do nothing. Back to the story. While the Animorphs are walking around they come upon a HUGE Yeerk pool. It was more like a lake. You could have ridden a boat around in it and you wouldn't look out of place. A Bug Fighter then lands near the Yeerk pool. A Bug Fighter is the smallest kind of spaceship the Yeerks have. Rachel, an Animorph, feels drawn to the Bug Fighter, so she and Ax walk over to it. Since everyone thinks Ax is Visser One, the most powerful Yeerk, everyone stays out of their way. Then the real Visser One steps out, along with another Rachel who is a Controller. After Rachel knocks Visser One down, as a bear, they are transported back to the present by the Ellimist. That night Rachel has a dream and figures out where the Kandrona is. After gathering everyone up, they go to the EGS Tower. Next they morph into their dangerous animals and break in and go to the top floor. There they go into a room where eight Hork Bajir Controllers are guarding the Kandrona.Hork Bajir are aliens taken over by the Yeerks. After a huge battle The Animorphs go into another room where the Kandrona is. Then they go home,with a victory. Bibliography Animorphs, The Stragegy Acceptance Essays

Free Essays on Budda

Buddhism is one of the biggest religions founded in India in the 6th and 5th cent. BC by Siddhartha Gautama, called the Buddha. One of the great Asian religions teaches the practice of the observance of moral precepts. The basic doctrines include the four noble truths taught by the Buddha. Since it was first introduced into China from India, Buddhism has had a history that has been characterized by periods of sometimes awkward and irregular development. This has mainly been the result of the clash of two cultures, each with a long history of tradition. Most of the difficulties have arisen due to the transplanting of an Indian religious/philosophical system onto a culture strongly dominated by indigenous secular, philosophical and religious systems. In spite of these difficulties, Chinese Buddhism has come to have an important influence on the growth and development of Buddhism in general and this has occurred largely because of its own innovatory contributions. (Eliade, M. p.16-29) T he spread of Buddhism into China began in Central Asia and was facilitated by the efforts of the Indo-Scythian king Kanishka (Encyclopedia Britt. 273-274) of the Kushan dynasty, which ruled in northern India, Afghanistan and parts of Central Asia in the 1st and 2nd centuries (Encyclopedia Britt. 274). He is said to have undergone an Ashoka-like conversion upon seeing the slaughter caused by his campaigns. Around the beginning of the Common Era, Buddhism started to filter into China from Central Asia via the Silk Road, brought by monks, merchants and other travelers. It also entered later via trade routes around and through Southeast Asia. It was nurtured in the expatriate community of Loyang and other northern cities. (The Encyclopedia of Religion p58-62) Siddhartha (Buddha) was born around 563 B.C.E. in the town of Kapilavastu (located in today's Nepal).

The Modern World Economy Essay Example | Topics and Well Written Essays - 2000 words

The Modern World Economy - Essay Example The essay "The Modern World Economy" talks about infant argument claims in terms of the modern world economy and analyses the experience in this question of different countries. The experience of West Germany, the United States, Japan and South Korea suggests that governmental support in promoting infant industries did assist efficient industrialization processes to some extent. However, the experiences of other countries, mainly the developing countries, seem to suggest that protection policy has been frequently abused. Therefore, it is not surprising to find a large body of literature which exhibits considerable skepticism concerning the success of infant industry protection in developing countries. The effective rate of protection has been high for most import-competing industries for a long time and export performance has been poor, with most of them being orientated towards the domestic market. Recent writings in the theory of international trade suggest that IS and EP industrial strategies are not mutually exclusive. For example, Krueger (1995, p. 207) have argued that these two strategies are sequential rather than being alternatives and they can be compatible rather than separate strategies. They have further asserted that IS is needed not only for creating export ability, but also for providing the volume basis necessary for competitive exportation. Indeed, this is the core of the infant industry argument. Empirically this view has been supported by South Korea's success in its policy of pursuing both EP and IS strategies simultaneously.

Candombl Religion Research Paper Example | Topics and Well Written Essays - 1000 words

Candombl Religion - Research Paper Example The religion is founded on the soul of Nature, but also displays elements of African mythology and culture. The popularity of Candomblà © is due to the combination of many religions into one, making it agreeable to a variety of potential followers and one of the most sough-out religions in Africa and Europe. When a religion is considered to be syncretistic, it means that it is a combination of two or more religions or cultures, pulling beliefs, stories, and, oftentimes, deities from other religions. Candomblà © is a combination of three main African religions, Yoruba, Fon, and Bantu. Muslim traditions have also been incorporated, though these were more common during the slave trade in Brazil. The only Muslim tradition that is still observed in Candomblà © is believing, and thus practicing, the use of Friday as the only day worthy of worshipping deities, praying, and meditating. Many local Native American deities were also used in rituals, though this practice did not last long due to the Catholic Church looking down upon such practices, thus not allowing their slaves to implement them into their practices. Catholicism is yet another religion whose beliefs and practices have been adopted by the Candomblà © religion. This was due to the fact that â€Å"many Christian slave owners and Church leaders felt it was important to convert the enslaved Africans. This was in order to fulfill their religious obligations [...] (â€Å"History of Candomble).† A connection was found between the worshipping of saints in Catholicism and the worshipping of ancestor deities in Candomble, so the Candomble practitioners secretly combined their deities with the saints of Catholicism. Deities and Beliefs Candomble is a polytheistic religion, recognizing and worshipping more than one god. They believe in an all-powerful God, Oludumare, and the lesser deities that serve him. These lesser deities are known as orixas, voduns, and inkices. Orixas are ancestors that, upon death, become viewed and treated as gods. They each represent a specific force in nature and a certain food, animal, or color. Voduns and inkices are spirit gods, similar to orixas; the three lesser deities share the duty of acting as a connection between the spiritual world and the human world, passing along messages or searching for cures to illnesses. The greatest difference between orixas and voduns and inkices is that it is believed that every human being has their own orixa, whose duty it is to control the destiny of that person, as well as to protect them (Voeks 57). It is also a belief of Candomble practitioners that a person’s personality and defining characteristics are dependent on that person’s orixa. Candomble maintains a belief similar to that of karma, which is more common in Buddhism and Hinduism. Karma is the belief that a person’s actions in the present will influence or have an effect on their lives in the future or in another life. Candomble holds t hat there are no concepts of good and evil. Each person has the task of fulfilling their destiny in whatever way they need to, regardless of what that destiny is. However, if a person succumbs to evil to fulfill their destiny, their actions will come back to them, essentially returning their evil. This belief prevents people from doing anything that they want, allowing them to understand that their are consequences to their actions. The Candomble have a variety of moral codes that they most follow, though these tend to change from generation to generation. It is the job of the Baba Egum to regulate and update the moral responsibilities of their people. The Baba Egum are in charge of making sure that the essential moral codes
