Beethovens 7th Symphony essays

Beethoven's 7th Symphony essays Beethoven's 7th Symphony First, a little history on why this piece is different than Beethoven's other Symphonies. After Beethoven's marathon concert of December 1808, which included the first performances of his Fifth and Sixth Symphonies, the city of Vienna was not to hear a new Beethoven symphony for some five years. The long-awaited Seventh was completed about May of 1812. The Seventh can be seen as Beethoven's atypical use of the wind instruments as a self-contained group in the orchestra, rather than as the amplifier of an essentially string-dominated texture or as a collection of soloists dependent upon string accompaniment. The special treatment of the wind plays as important role in the shaping of the work, although Beethoven's orchestra here is the same size as that of his first two symphonies, he can expand his material by setting large instrumental groups against each other. In the Vivace itself, which is in sonata form, the normal roles of string and wind are sometimes actually reversed, so that (for example) it is the wind - and led by the flute rather than, more conventionally, by the trumpet - which gets to play the opening statement of the first subject. The second movement's rhythm, its ABA form (modified, and with a coda recalling both elements) and its tonal organization (the B section is in the parallel key of A major and gives prominence to the wind) each underscore its relationship to the somber processional march of the early 19th century. Though the form of scherzo, ABABA', has become standard in this Beethoven symphony, it's remote key relation between the principal section and the t rio (F major - D major) was something new; what is more, Beethoven emphasizes the tonal distance between them by basic differences in tempo, phrase construction and the use of the orchestra. Then he bound together these two seemingly irreconcilable musical entities. As a result, Beethoven is able not only to reinforce the forti...

Plastic Surgery Essays Plastic Surgery Essay Plastic Surgery Essay also known as ultrasonic liposuction the cannula is energized with ultrasound. This makes the fat melt away on contact the ultrasound vibrations burst the walls of the fat cells, emulsifying the fat (liquefying it) and making it easier to suction out. This method is a good choice for working on more fibrous areas, such as the male breast, back, and in areas where liposuction had been done before. UAL is especially useful for stubborn fat accumulations. However, longer incisions in the skin are needed for this procedure, and there is a risk of skin or internal burns. This procedure takes longer than the others, because it is often done alongside tumescent liposuction. It is also more expensive. After ultrasonic liposuction, it is necessary to perform suction-assisted liposuction to remove the liquefied fat. UAL techniques were initially linked with cases of tissue damage, generally because of over-exposure to ultrasound energy. A third-generation UAL device the Vaser Lipo system prevents this problem by using pulsed energy delivery and a specialized probe that allows surgeons to safely remove excess fat. * Power-assisted liposuction (PAS) , also known as Powered liposuction uses a specialized cannula with a mechanized system that rapidly moves back-and-forth, allowing the surgeon to pull out fat more easily. It is similar to traditional UAL, but the surgeon does not need to make so many manual movements, as in other methods. This method may sometimes cause less swelling and pain, and may allow the surgeon to remove fat with more precision, especially in smaller areas. * Laser Assisted Lipolysis (LAL) , or laser-guided lipo requires the use of tumescent fluid. It is a far less invasive and bloody procedure than the traditional liposuction method for removing fat. A microcannula is inserted through a small incision to deliver laser energy and heat into subcutaneous fat (fat under the skin). The liposuction cannula this is a stainless steel tube, which is inserted through an incision in the skin and is used to suction the fat (suck the fat out). The liposuction microcannula is a very small cannula with an inside diameter of less than 3 mm (some experts define them with less than 2. 2mm diameter). Liposuction surgery tools The size of the cannula can influence how smooth the skin is after liposuction. Large cannulae tend to create irregularities more commonly than microcannulas. Large cannulae are more frequently used for total-body liposuction. After an area has been prepared for treatment, a small cut is made (sometimes several, depending on the size of the area), and a microcannula is inserted into the cut. The microcannula is attached to a special vacuum machine. The microcannula first loosens and then sucks the fat out of the area. Draining out excess fluid and blood after the operation the surgeon may leave the incisions open so that fluid can drain from the body. After the liposuction operation * Anesthetic patients who underwent a general anesthetic usually spend the night in hospital. Those who had a local anesthetic may be able to leave hospital on the same day. Patients should not drive for at least 24 hours after receiving an anesthetic. * Support bandages the patient will be fitted with either an elasticated support corset or bandages for the targeted area after the operation. They help reduce inflammation and bruising. They should be worn for several weeks. It is important to follow the doctors advice on keeping the area clean and how to do this. * Antibiotics patients may be given antibiotics immediately after the operation. * Painkillers the doctor will most likely prescribe or recommend analgesics (painkillers) to relieve pain and inflammation. * Stitches the patient will be given a follow-up appointment to have the stitches removed. * Bruising there will be significant bruising in the targeted area. The amount of bruising is usually linked to how big the targeted area was. The bruising may go on for several weeks; in some cases for as long as six months. * Numbness patients may experience numbness in the area where fat was removed. This should improve within six to eight weeks. Results patients and their doctors will not be able to fully appreciate the results of liposuction until the inflammation has gone down, which in some cases may take several months. Typically, most of the swelling will have settled after about four weeks and the area where fat was removed should appear less bulky. Patients who maintain their weight can usually expect permanent results. Those who gain weight after the procedure may find that their fat distribution alters. Those who previously had fat accumulating in their hips might find that their buttocks become the new problem area. If a patient has thought everything through carefully beforehand, talked to their GP and surgeon about their aims, motives and expectation, the surgeon is skilled and well qualified, and there are no complications, most patients are pleased with their results. What are the risks of liposuction? Any type of major surgery carries a risk of bleeding, infection and an adverse reaction to anesthesia. Risk of complications is usually associated with how large the procedure is, as well as the surgeons skills and specific training. The following risks, unpleasant side effects, or complications are possible: * Bad bruising this is especially the case if patients have been taking anti-inflammatory medications or aspirin. Patients with a tendency to bleed are also at higher risk of bad bruising. * Inflammation the swelling in some cases may take up to six months to settle. Sometimes fluid may continue to ooze from the incisions. Thrombophlebitis a blood clot forms in a vein, causing inflammation of that vein. This may affect liposuction patients, especially inside the knee and on the inside of the upper thigh (when these areas have been treated). * Contour irregularities if the patient has poor skin elasticity, has healed in an unusual way, or fat removal has been uneven, the skin may appear withered, wavy or bumpy. This undesirable result may be permanent. The cannula may cause da mage that makes the skin appear spotted. Seromas may form under the skin (temporary pockets of fluid), which may need to be drained. Numbness the area that was worked on may feel numb for a while; this is usually only temporary. There may also be temporary nerve irritation. * Infections although rare, skin infections may occur after liposuction surgery. Sometimes this needs to be treated surgically, with the risk of scarring. * Internal organ punctures this is very rare. If the cannula goes in too deeply one of the internal organs may be punctured. Further surgery may be required. Internal organ punctures can be life-threatening. * Death anesthesia carries with it a small risk of death. Kidney or heart problems as fluids are being injected and or suctioned, the change in the bodys fluid levels may cause kidney or heart problems. * Pulmonary embolism fat gets into the blood vessels and travels to the lungs, blocking the lungs. This can be life-threatening. * Pulmonary edema th is may be a result of fluid being injected into the body. Fluid accumulates in the lungs. * Allergic reaction there may be an allergic reaction to medications or material used during surgery. * Skin burns the cannula movement may cause friction burns to the skin or nerves. Lidocaine toxicity in the super-wet or tumescent methods, too much saline fluid may be pumped into the body, or the fluid may have excessively high concentrations of lidocaine. If lidocaine levels are too high for the patients system he/she may experience lidocaine poisoning (toxicity) initially they will experience tingling and numbness, then seizures, followed by unconsciousness, and possibly respiratory or cardiac arrest. medicalnewstoday. com/articles/244066. php What Is A Facelift? What Is A Rhytidectomy? Editors Choice Main Category: Cosmetic Medicine / Plastic Surgery Article Date: 12 Apr 2012 13:00 PST email to a friend    printer friendly    opinions Current ratings for: What Is A Facelift? What Is A Rhytidectomy? Patient / Public:| | 2 (4 votes)| Healthcare Prof:| | | Article opinions:|   1 posts| | A facelift is a surgical procedure that is typically used to give a more youthful appearance to the face. Technically, it is also called a rhytidectomy. This type of cosmetic surgery reshapes the lower one-third of the face by removing excess facial skin. Some facelift procedures also include the tightening of underlying tissues. To achieve the best result, it is often combined with other additional procedures addressing the forehead, cheeks, brows and eyes. According to statistics, facelifts are increasingly popular among both men and women. The first facelift was performed in Berlin in 1901 by surgeon Eugen Hollander. According to Medilexicons medical dictionary, a rhytidectomy is: Literally, excision of wrinkles. Usually used to designate rejuvenative surgery of the cheeks and neck performed by tightening the facial supporting structures and excising excess skin; face-lift. The facelift procedure The traditional facelift. An incision is made in front of the ear extending up into the hair or hairline. The incision stretches downward in front of the ear, comes under the ear and then upward behind the ear. It then ends in the hair or hairline behind the ear. If necessary, the deeper tissues of the face can be tightened. The excess skin is removed. The incisions are then closed with sutures and staples. In some cases a drain is placed under the skin behind the ear to drain off any excess blood and fluids. This drainage tube is removed a day or two after the procedure. Then bandages are applied. New surgical techniques There are new methods for performing facelifts. New surgical options are constantly being developed. These advances aim at improving cosmetic procedures: * Lasers: A face-lift procedure called laser neck and jaw liposculpture and resurfacing, uses lasers. This can be done through a one-inch incision under the chin using only a local anesthetic. * Endoscopy: Endoscopic techniques are now used to do face lifts and brow lifts. This method allows for smaller incisions. As a result, there are fewer traumas to tissues, and a faster recovery time. Facial structures are raised, and there is no need to cut away folds of skin. However, this type of procedure also depends on the patient. * Liposuction: This method is used to remove focal deposits of fat in the face. It is usually used in the area between the chin and neck. Liposuction can be combined with a face lift or performed separately. Face lift surgery can last from two to five hours. It can be performed in an outpatient facility with local anesthetics and sedatives to relax the patient. However, in some cases surgery can be performed under general anesthesia and the patient may stay in the hospital overnight. Facelifts are effectively combined with eyelid surgery and other facial procedures. The result of a facelift is a smoother, more youthful appearance. The procedure removes and tightens sagging skin. The droop of the cheeks around the jaw line is reduced. The corners of the mouth are lifted and the creases between the cheeks and lips are diminished. The results usually last between five to ten years. Ads by Google Most Advanced Liposuction New Technique Simple Safe Effective Faster Recovery Free Consultation HealthPathwayIntl.

For a satisfactory and pleasing result, the adequate techniques are required in each individual case. In men, achieving a natural appearance following surgery can be more challenging because men have hair in front of their ears (sideburns). The sideburns can be pulled backwards and upwards. This may result in an odd look. In both men and women, one of the obvious signs of having had a facelift is a distorted earlobe. If skin is removed in excess, the face can assume a pulled-back or startled appearance. Additional procedures to supplement the facelift may be necessary for optimal results, including neck lift, eyelid surgery, liposuction, fat injection, removal of cheek fat, forehead lift, brow lift, chemical or laser peel, and cheek or chin implants. What are the complications of facelift surgery? Complications of facelift surgery are infrequent cosmetic procedures are generally safe. However, any surgery comes with some risk. The risks and complications of facelift surgery include: * Bleeding * Bruising * Complications of anesthesia * Damage to the facial nerves controlling muscles (usually temporary) * Hematoma (inflammation, pain, swelling and redness) * Infection * Loss of hair although uncommon (around the incision site) * Numbness (can improve within days or weeks) * Scarring * Skin necrosis (tissue death) * Unevenness between two sides of the face * Widening or thickening of scar Recommendations for facelift surgery Most patients are very pleased with the results of their facelifts. The following points should be discussed and considered before going forward with a facelift procedure: * Undergoing a facelift surgery is not recommended for anyone with serious medical problems. * The individual who is considering undergoing the procedure should be in good general health. * The risk of postoperative complications is increased in cigarette smokers. * There is a higher risk of complications for patients with high blood pressure and diabetes. * The patient should have reasonable expectations. Surgery will not detain the overall aging process. * Patient should be psychologically stable. For best results, patient should have good skin elasticity and bone structure. * Patients should abstain from taking aspirin or other blood thinners for at least one week prior to surgery. Prior to surgery, the plastic surgeon will review the patients medical history. There will be analysis and evaluation of blood pressure, blood clotting, medications, cigarette smoking, drug use, aller gies, scarring, and skin condition. Moreover, the plastic surgeon will discuss with the patient what the surgery will involve, where it will take place, the type of anesthesia used, the recovery, and potential complications that may develop. The surgeon and patient should discuss thoroughly what the goals and expectations of the surgery are, according to the skin type and bone structure. Recovery after your facelift Pain and discomfort are usually minimal and medication can be given to relieve tenderness. Most patients do experience a slight discomfort after a facelift. Bruising and swelling can persist for a few days. Recovery time is usually one week but activities can begin the day after the procedure. Sutures are removed about five to ten days after surgery. Incisions and bandages must be kept dry and the patient should follow the specific instructions about bathing and washing. Vigorous activity should be avoided for some time. Following doctors directives is crucial and will speed the healing process, allowing for the best possible result. Full recovery takes about two to three weeks while bruises heal and swelling diminishes. Some numbness and muscle stiffness is normal for some time. Scars can take nearly a year to fade and tone down. Most patients are very satisfied with the results of their facelift. They feel that they have recovered a more youthful appearance. Both men and women enjoy their rejuvenated look. The results of a facelift can last approximately 10 years. Genetics and lifestyle factors play a role in aging and the appearance of skin. A healthy lifestyle, including not smoking or drinking alcohol, limiting stress, sun exposure and contact with pollutants can help extend the beneficial effects of the facelift surgery.

Thousands of people have these operations done every year to change their face and body. What many of these people dont realize is that there are negative effects to the surgery, ranging from emotional issues to cost and the risks they take when they lie on the table.

Side Effects * Though thousands of people undergo cosmetic and plastic surgery every year, there are some side effects to the procedures. This varies depending on the exact operation. Some patients have experienced headaches, nausea and prolonged pain. Another common side effect reported is inflammation surrounding the area of the body where the procedure was done. These side effects generally dissipate over time but can be bad in the beginning. Individuals may also experience bruising in areas of their body. Cost * When people decide to undergo cosmetic surgery, they often consult a professional who gives them an estimate as to the cost. This estimate isnt a binding contract, but a guess as to how much the procedure will cost. The actual cost can rise dramatically over this estimate, leading patients to suffer pressure to pay the entire amount even if they cannot afford it. When the cost is spread out over a payment plan, it can cause more stress. * Sponsored Links * Mens Skin Centres Enjoy Power Tummy Sculpting @RM190. Tough ABS the easy way, Sign Up Now www. MenSkinCentre. com. my/Body Emotional Effects * The emotional effects on patients well-being are one of the negative effects of cosmetic surgery. While they go under the knife to fix a problem they see on the outside, this sometimes only serves as a bandage on the larger problem. After the surgery they continue to suffer from a body image distortion. A small number of patients continue to go back to the surgeon to fix other problems they see instead of trying to find a real solution to the problem. Risks * Risks are a negative side effect of cosmetic surgery because theyre dramatic and varying. Whenever an individual steps under the knife, they open themselves up to risks associated with the surgery. There are cases of individuals dying on the operating table, even during a routine procedure. The individual also has to worry about risks associated with an infections, allergic reactions and organ failure. These only occur in a small number of cases, but they are still something to consider. Scarring * Scarring is something that many people dont consider when it comes to cosmetic surgery. However, in certain cases this type of surgery can leave behind lasting scars that dont fade over time. Breast augmentation and liposuction are two of the more popular procedures that cause scarring. The surgeon can later attempt to correct the scarring or reduce the appearance, but this doesnt always work.

MedivironUOA. com Plastic surgery is the surgical method of correcting or restoring body parts and their functions. The word plastic comes from the Greek word plastikos, which means to mold. This surgery also involves molding or shaping the body features and parts either for enhancing the appearance of an individual or for restoring a deformed body part and its functions. Accordingly plastic surgery is categorized into two main fields, cosmetic surgery for enhancing looks and beauty, and reconstructive surgery, which is carried out for the purpose of restoration of damaged body parts. Reconstructive plastic surgery is mainly performed in the case of severe burns, injuries, congenital defects and developmental abnormalities of organs, infections or diseases and for cancer or tumor removal. The history of plastic surgery, especially for reconstructive purposes, dates back to 2000 BC, India. Today, we have witnessed an increase in the popularity of plastic surgery, mainly for cosmetic purposes. No doubt cosmetic surgery can effectively reshape the body parts to give you a beautiful and young look, free of wrinkles and scars and thereby boost your morale. However, several bad or negative effects may also be associated with the process, which can range from financial to physical and psychological effects. Ill Effects of Plastic Surgery Cost Plastic surgery is a very expensive procedure, which involves skin grafting. It can put tremendous financial pressure on you and your family. While assessing the cost of this surgery, people tend to take into account only the cost of the surgery, and completely overlook the unexpected cost that can arise from postoperative complications and the hospital charges they ave to shell out in case they have to stay back in the hospital for any postoperative procedure. People also forget to consider the cost of postoperative medications, which cant be avoided, as not taking them can result in further complications. In all, plastic surgery is a costly and complicated affair and considerable care and precautions need to be followed after the surgery. Surgical Risks Plastic surgery involves several surgical ri sks like pain, infections, allergic reactions, nausea and vomiting, which are commonly associated with any kind of surgery. In addition to these, drug reaction, implant rejection, pigmentation, blood clots, skin necrosis and nerve damage on the particular area are some of common adverse effects of this surgery that may give rise to many complications. The process may produce additional risks for smokers, as they are more likely to face problems like delay in healing wounds, increased risk of infection, bruising, and pulmonary problems. In rare cases, plastic surgery can lead to heavy blood loss and organ failure. Psychological Impact Patients opting for plastic surgery, especially cosmetic surgery, should be very well aware that the results they obtain might differ from what they were expecting before they went under the knife. Sometimes these procedures can leave behind scars that may not go away with time. This can have a lasting psychological effect on patients, plunging them into depression. People suffer from intense regret and anger toward themselves and the doctor for a procedure gone horribly wrong, not to mention embarrassment and criticism they might face from friends and family. It has been observed that many individuals undergoing plastic surgery tend to suffer from an obsession with their look. This can cause an addiction and may impel them to undergo plastic surgery several times. A common psychological disorder in this regard is known as body dysmorphic disorder, where people develop such a distorted and weird perception of their body that they cant be satisfied with any look. But sometimes plastic surgery becomes inevitable, especially for reconstructing damaged parts of the body caused by burns, accidents or any inborn abnormality. Before opting for plastic surgery, patients must be well aware of every risk that is associated with this procedure. It is very essential to discuss every aspect of the method and the cost involved with your plastic surgeon. It is also advisable to research properly before selecting a qualified and certified surgeon. Look for his professional records, affiliations, medical accreditation, etc. to ensure you are in safe hands. Follow the instructions of your surgeon to avoid any surgical and post-surgical complication and be mentally strong and prepared to handle the repercussions, if any.

How has Christ been Understood to be Present in the Eucharist Essay

How has Christ been Understood to be Present in the Eucharist - Essay Example This essay stresses that Christ is not only the author and minister of each sacrament, but equally the exemplar of the grace which each sacrament is designed to realise, by naming explicitly the grace or virtue conveyed in and through each sacrament. In the Eucharist, this particular grace is self-giving. Macquarrie forwards the idea that through these sacraments, â€Å"things† which are considered otherwise ordinary are taken to new spiritual levels, or people’s understanding of them have, by virtue of the persistence of their faith, undergone intense deepening. Hence, bread which is of the earth and which human hands have made become the â€Å"Word of Life† and Wine, normally considered the fruit of the vine and a product of human toil and labor, becomes the â€Å"spiritual drink† and the â€Å"cup of our salvation†. This paper makes a conclusion that there is no doubt that the Eucharist is very important in the Anglican Church. No one by a bishop or presbyter may administer the Eucharist and it mandates that â€Å"pure wheaten bread and wine, being the fermented juice of the grape, are the necessary elements of the Sacrament.† The doctrine of the Catholic Church and the Anglican Church with respect to Transubstantiation was one and the same. When the reign of Edward VI ushered in a more Protestant ideology, transubstantiation was refuted and denied. The Doctrine of Transubstantiation, many Anglicans believe, tend to obscure the deeper meaning of the Eucharist.

Econ160 - Essay Example My parents belongs to several generation of Guanxi where I am expected to inherit his position. If I will be living in China, I better be sure with the place that I will live. It is because the Chinese government prohibits the reselling of houses as their policy response to avoid speculation in the housing industry. I will be stuck in the house that I will choose for a very long period of time so I better take my time before buying a house. Unlike in the US where the housing market is determined by market forces as enunciated by Friedman in the book Capitalism and Freedom where price and availability is determined by the law of supply and demand where I can resell my house anytime I want it subject to the same law (supply and demand), Chinese government will just not allow the resell and even pegged the price. China may now allows private ownership of houses only with restrictions. With my present economic stature, I believe I would be able to afford a house and not in a crampy apartment or shoebox as what Hedrick Smith had described in his book The Russians. Only that my house will not form part of my estate where I can resell for profit or I will go to jail. If I will be in China, choosing my occupation will be partly determined with how the â€Å"opportunities† present to me. Unlike in the US where choosing an occupation is determined by personal preference and applying on it base on merit, it will be different in China. The cliche its whom you know more than what you know applies. If my father belongs to a Guanxi or the network of power elites, he may recommend me to some of his associates in the network as expounded by McGregor in his book The Party and will accept whatever occupation that will be given to me. From there, my future will be secured because I will be under the patronage and care of my father’s Guanxi and I will later develop my own network. I will first learn the rope of the business until I

Analyze Capital Budgeting Methodologies (NPV, IRR, MIRR, etc..) Research Paper

Analyze Capital Budgeting Methodologies (NPV, IRR, MIRR, etc..) - Research Paper Example Some of the major capital budgeting techniques are: 2. Where â€Å"NPV† is â€Å"zero†, it is acceptable to the organization as it promises equal return to the required rate of return. However, the organization is in differential towards such a project, as it gives no profit. This technique uses discounted cash flows in its analysis, which makes it one of the most accurate capital budgeting techniques. This is because it incorporates and considers both the risk and time variable aspect of the project. Therefore, it measures the net benefit of the project in today’s currency terms (Accounting4managment, n.d). One of the major limitations of NPV method is its difficulty to make accurate forecast of the future cash flows and another is its vulnerability of manipulation through different discount rates as there is no standard to set a discount rate (Michel, 2001). Internal Rate of Return or also called yield on project is actually the rate of return of the investment project earned over the useful life of the project. The benefits and cost of the project are equal to each other at this discount rate. In other words, it is the discount rate where the NPV of the project is zero (Accounting4managment, n.d). There is no specific direct formula for manual calculation of IRR. Instead, the calculation is based on the equation where NPV id zero using various cash flows at different discount rates. However, it can be easily calculated on Excel and financial calculators. 1. Where â€Å"IRR† of the project is greater or equal to â€Å"project’s cost of capital†, the organization accepts the project as it indicates that the return is higher than what organization pay to borrow money for the project. 2. Where â€Å"IRR† of the project is lower than the â€Å"project’s cost of capital†, the organization rejects the project indicating that it would obviously not prefer to receive a return lower than what they pay to borrow

Cogeneration And Trigeneration Methods Engineering Essay

Cogeneration And Trigeneration Methods Engineering Essay Cogeneration and trigeneration are methods used for producing more than one useful form of energy from only one energy source. These two methods in todays world are very important because efficiency, fuel prices and emissions are a great a concern. Both methods give the opportunity to increase efficiency drastically up to 60% to 80% which is much more than the conventional power plant which has an efficiency of about 30%.  [1]   The 60% to 80% efficiencies that both methods present have a great effect on cost savings, reduced air pollution, greenhouse gas emissions, increased power reliability and quality, reduced grid congestion and avoided distribution losses.  [2]  All these factors mentioned, as discussed before are all important and cogeneration and trigeneration help achieve this. Both systems are normally combined but I will explain both cogeneration and trigeneration separately and then give examples were these systems are used in real life. Cogeneration Cogeneration is also known as combined heat and power (CHP). Plants using a cogeneration system use the exhaust of for example a reciprocating engine to heat the premises. This means that instead of throwing away the exhaust, it is being reused but this time as heat energy. This is done by using a heat exchanger to transfer heat from the exhaust gas to process heat. Cogeneration produces a given amount of electric power and process heat with 10% to 30% less fuel than it takes to produce the electricity and process heat separately.  [3]   Cogeneration Combined Heat and Power Figure 1: Cogeneration diesel engine generator plant  [4]   Figure 1 above shows a diesel engine driving a generator. Fuel in the form of natural gas, bio gas or bio diesel is used to run the engine. The engine is coupled to a generator which produces electricity. The plant above shows two heat exchangers, one for cooling the engine and raising the used cold water coming from process heat and the other is an exhaust gas heat exchanger only to raise again the temperature of the water for process heat. The water cooling the engine which is normally at around 90oC enters the heat exchanger (bottom one) which by heat transfers and the second law of thermodynamics is cooled but the cold waters temperature is raised. In the exhaust gas heat exchanger the temperature of the water already heated in the bottom heat exchanger is heated again and sent for process heat. A simple example is, imagine a hotel having a generator to produce electricity and at the moment its full of guests and the ambient temperature outside is around 2oC below zero. This means that the central heating needs to be running constantly to keep the guests in a comfortable environment. Therefore a lot of fuel is being used to heat up the boilers to produce steam for central heating. Imagine the hotel employs the plant shown in figure 1. No fuel will be used for heating because the fuel used to run the engine is also being used (indirectly) for process heat. There exist two main types of cogeneration techniques which are topping cycle and bottoming cycle plants. Topping cycle cogeneration plant Topping cycle plants generate electricity or mechanical power first. Some facilities may generate the electricity for themselves only and some may even sell any power that is not being used. There exist four types of topping cycle cogeneration plants. Combined cycle topping system The first type burns fuel in a gas turbine as shown in figure 2 or diesel engine to produce electrical or mechanical power. Process heat, or steam that then drives the secondary steam turbine is produced by the exhaust entering a heat recovery boiler.  [5]   Figure 2: Combined cycle topping system  [6]   Steam turbine topping system The second type of system burns fuel which can be any type to produce high-pressure steam that then passes through a steam turbine to produce power. The exhaust provides low-pressure process steam as shown in figure 3.  [7]   Figure 3: Steam turbine topping system  [8]   Heat recovery topping system This type burns a fuel such as natural gas, diesel etc. The cooling system (engine coolant) goes to a heat recovery boiler, where it is converted to process steam and hot water for space heating. Figure 4: Heat recovery topping system Therefore this type produces electricity, process steam, hot water supply and heating as shown above in figure 4.  [9]   Gas turbine topping system This type of system uses a natural gas turbine to drive a generator. The exhaust gas goes to a heat recovery boiler that makes process steam and process heat as shown in figure 5.  [10]   Figure 5: Gas turbine topping system  [11]   Bottoming cycle plants These type of plants are less common then topping cycle plants. Normally this type of plant is used in heavy industries where high temperature furnaces are used. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhL_TnW5IfyrsRFXmEx71rqd6-HKYClFz5YGVE85Wx9eYfKaReg5pogWXgYPvKeb6xAWsLgUOxrZEVk8ar7j1G0y2Ub3-xNrh_19q8jsa-WWALYPgP6MB3rFMr7DB8PkHUjslQ6f_s-hyM/s1600/bottoming-cycle-system-cogeneration.jpg Figure 6: Bottoming cycle system  [12]   After heating the furnace or any manufacturing heating process the waste heat is then passed through a recovery boiler. The waste heat is used to produce heat which then drives a steam turbine to produce electricity. Trigeneration Trigeneration also referred to combined heating, cooling and power (CHCP) is a system where this time three types of energies are produced from one energy source. The difference between cogeneration and trigeneration is that in trigeneration chilled water for air conditioning or process use is produced. This is done by using an absorption or adsorption chiller. Just as a cogeneration power plant captures and makes use of the waste heat, absorption or adsorption chillers capture the waste (or rejected) heat and produce chilled water.  [13]   Therefore the major advantage over cogeneration is that now if a plant works using trigeneration, hot water, air conditioning (using chilled water) and power generation. Therefore an industry having this system will spend less money due to having a more efficient plant when compared to cogeneration and especially when compared to conventional plants. Adsorption Chiller An adsorption chiller works purely using hot water. It uses the principle of using solid sorption materials such as silica gel and zeolites. http://www.raee.org/climatisationsolaire/graph/new/adsorption_sh.gif Figure 7: Schematic for an adsorption chiller  [14]   These type of chillers have a strong structure and are easy to install. There are no possibilities of crystallization, corrosion, hazardous leaks, and the electricity consumption is minimal  [15]  . They are commonly used in a commercial environment. Absorption Chiller An absorption chiller works by using hot water, steam or combustion. The solution used contains water and lithium bromide salt to absorb heat from the surroundings. No refrigerant is used which means no harm is done to the environment. http://www.raee.org/climatisationsolaire/graph/new/absorption.gif Figure 8: Schematic for an absorption chiller  [16]   Absorption chillers are the most distributed worldwide and they are more efficient. Their lifetime is much longer than adsorption chillers. Moreover they have high maintenance time and low corrosion protection.  [17]   Say something small about trigenerators and put schematic of plant.

Environment Analysis of Greater Manchester County Essay -- Environment

My essay focuses on the county of Greater Manchester in North West England. A thriving metropolitan area, the county has been a place of interest since its rise in the Industrial Revolution. Greater Manchester is a landlocked county in the North West region of England. The Pennine mountain range runs along its northern and eastern borders, whilst the West Pennine Moors are found on its western border. To the south lies Cheshire, a flat county with large plains left by glaciers in previous Ice Ages. Greater Manchester therefore has a graded profile, with steep mountains and hills to the north-east gradually settling out to low-lying, fertile plains in the south-west. The county’s geology consists mainly of rock from 3 geological periods; the Carboniferous, Permian and Triassic, alongside glacial deposits left over from Ice Ages in the Quaternary period. The oldest rocks seem to be found in the north-east of the county, and the youngest in the south-east. The Permian and Triassic rocks laid down are indicative of hot, desert conditions with the formation of mudstones and sandstones; Red Permian sandstones are overlaid by red, brown and yellow Triassic sandstones and mudstones from the Sherwood Sandstone Group. These rocks are found mainly in southern Greater Manchester. (Natural England). Glacial till is also common in the low-lying areas to the south and west of Greater Manchester. Following frequent changes in climate in the Quaternary period, glaciers have advanced and retreated leaving a layer of glacial deposits in their wake (Natural England). These deposits were transported downstream via meltwater rivers to lowland areas, making them fertile and very useful for pastoral farming. As such, lowland areas have become popula... ...ved January 16, 2011, from Crimestop Guards: http://www.crimestopguards.co.uk/manchester.htm Geology Roam. (n.d.).
