A Career in Dentistry nbsp;nbsp;nbsp;nbsp;nbsp;Children are often sweet and adorable, but many times they may be eating too many sweets. According to the Channel Four News, it has been shown that the number one disease in children is the reoccurrence of caries, also known as cavities. Could it be too many sweets or could it be the lack of flossing and brushing teeth? For instance, many children go to bed or wake up without brushing their teeth and go throughout the day eating all sorts of food and candy. The result of eating and not brushing could lead to plaque build up and decaying of teeth. This leaves a child extremely unhappy and in excruciating pain. So who is going to fix this pain? Who is going to help prevent decay in†¦show more content†¦During the fifth century B.C., a Greek historian named Herodotus wrote from his observations that medicine had become so separate that each physician was a specialist in a disease (Phinney 5). nbsp;nbsp;nbsp;nbsp;nbsp;Dentistry during early times primarily consisted of extracting a tooth if pain existed. Some scientists have found evidence of drilling holes near the roots of the teeth to allow any infection to drain so that pressure in the abscessed tooth could be relieved. It has been noted that Hippocrates was the father of medicine. He attempted to give a general understanding on health and disease. Among Hippocrates/ numerous writings is a book titled On Affections. He wrote, â€Å"Teeth are eroded and become decayed partly by the mucus and partly by food, when they are by nature weak and badly fixed in the mouth† (Phinney 5). Much of what Hippocrates wrote is partially untrue and some logically absurd, but has writings led many other people to look into the interesting studies of dentistry and medicine. nbsp;nbsp;nbsp;nbsp;nbsp;One of these followers in the quest to find better methods of dentistry was Aristotle. During has time more attention was put on oral hygiene. An Athenian physician, Diocles of Carystus, stated oral hygiene should get proper attention and he gave instructions to this end (Phinney 5). During the next few centuries, more importance was placed on good oral hygiene.Show MoreRelatedDentistry Career Paper : Dentistry1412 Words   |  6 PagesSeptember 2015 Dentistry Career Paper Dentistry is an ever-growing field in medicine that is very well paid and respected.

Othello Performance Analysis Essay Example For Students

Othello Performance Analysis Essay On the 25th of April 2015, I had the opportunity to catch the 8. 30 p. m. performance of one of Shakespeare’s greatest tragedies, Othello, at KLPAC. Directed by Lim Kien Lee and Qahar Aqilah, the show stars Grace Ng, Sandee Chew, Lim Soon Heng, Arief Hamizan, David H. Lim, Kgia Loong and Kien Lee himself in the title role. Shakespeare Demystified: Othello tells a tale of prejudice, love, envy, jealousy and murder – all in 100 minutes. The play starts off with Roderigo (Kgia Loong) telling Brabantio (David) that his daughter, Desdemona (Ng) has eloped with Othello, the General of the Venetian Army. He is not happy as Othello is of African and Arabian descent but Desdemona convinces him that she truly does love Othello. Meanwhile, Iago (Lim) who has been Othello’s comrade for many years is mad with rage as he was not chosen for the post of Leftenant. Instead, Othello chose Michael Cassio (Arief) for the post. Driven by envy, Iago spreads rumours of Desdemona’s affair with Cassio to Othello causing Othello to doubt Desdemona’s loyalty to her. The production used a very minimalistic set. Six black boxes were used and manipulated throughout the play to show the different settings. It is important to note that most of the time, it is often Iago who is moving the boxes around to show the next scene. According to Kien Lee, this was because in the plot, it is Iago who is doing all the manipulation through his words and actions. Therefore it seemed fitting that Iago should be the one ‘manipulating’ the sets. The lighting was plain white throughout the show due to the nature of the minimalistic set. In the original play, Othello is a black man. As Kien Lee is Chinese, the difference between Othello and the other characters was represented by a change in costume. The acting on a whole was quite convincing. Lims portrayal of Iago was superb. He managed to show Iagos evil side in a rather unconventional, quiet way. As for Grace Ng, the peak of her performance was during her rendition of the song Willow. You could almost feel her breaking in the song, torn between her love for Othello and the confusion regarding his behaviour. At one point it even felt like she was on the brink of suicide. The last person I would like to mention is Sandee Chews interpretation of Emilia. Several scenes involving Emilia were cut from the script to fit the time. Therefore the gradual change in Emilias character was speeded up greatly, although not too suddenly. And though only playing a small role, Emilias character brought up valid questions about the society those days, some of which are still relevant today. Kien Lees performance as Othello was a little too over the top. But then again, Shakespeares plays were always insanely dramatic. However, Kien Lees acting did not quite match the more natural acting style of the others. Also, his Chinese accent slipped out occasionally. Besides that, some of the words uttered by the actors ran together, making it extremely difficult to understand at times.

The Adventures Of Huckleberry Finn Essay Example For Students

The Adventures Of Huckleberry Finn Essay All children have a special place, whether chosen by a conscious decision or not, this is a place where one can go to sort out their thoughts. Nature can often provide comfort by providing a nurturing surrounding where a child is forced to look within and choices can be made untainted by society. Mark Twain once said, Dont let school get in the way of your education. Twain states that this education, which is provided by society, can actually hinder human growth and maturity. Although a formal education shouldnt be completely shunned, perhaps true life experience, in society and nature, are a key part of development. In the novel Adventures of Huckleberry Finn, Mark Twain throws the curious, yet innocent mind of Huck Finn out into a very hypocritical, judgmental, and hostile world, yet Huck has one escapethe Mississippi River constantly flowing nearby. On the river, nature is presented as a thought-provoking environment, when experienced alone. The river is a quiet and peaceful place where Huck can revert to examine any predicament he might find himself in: They went off, and I got aboard the raft, feeling bad and lowà ¢Ã¢â€š ¬Ã‚ ¦Then I thought a minute, and says to myself, hold on, spose youd a done right and give Jim up; would you felt better than you do now? No, says I, Id feel badà ¢Ã¢â€š ¬Ã‚ ¦ p.127. Only a few weeks with Jim and still feeling great ambivalence, Huck returns to the river to think. Twain tries here to tell the reader how strong the mob really is, and only when totally alone is Huck able to make the morally correct decision. The natural flowing and calm of the river cause this deep-thought, showing how unnatural the collective thought of a society can be. The largest and most obvious test of Hucks character is his relationship with Jim. The friendship and assistance which he gives to Jim go completely against all that sivilization has taught him. At first this concept troubles Huck and causes him a great deal of pain, but over time, through his life experiences and shared times with Jim, Huck crosses the line upheld by the racist South and comes to know Jim as a human being. Huck is at a point in his life where opinions are formed, and by growing on the river, Huck can stand back from society and form his own. Eventually he goes as far as to risk his life for Jim: And got to thinking of our trip down the river; and I see Jim before me, all the time, in the day, and in the night-time, sometimes moonlight, sometimes storms, and we a floating along, talking, and singing, and laughing. But somehow I couldnt see no places to harden me against him, but only the other kindà ¢Ã¢â€š ¬Ã‚ ¦I studied a minute sort of holding my breath, and then I says to myself: All right, then, Ill go to hellà ¢Ã¢â€š ¬Ã‚ ¦ pp.270-271. After a long and thought-provoking adventure, Huck returns to  the raft one final time to decide the fate of his friend. Symbolically, Huck makes the morally correct decision away from all others, thinking on the river. Although it might not be evident to him, Huck causes the reader to see that sivilization, in their treatment of blacks especially, is not civilized at all. Every person Huck and Jim come across seems to just be following someone else blindly, as the whole country was some sort of mob. In the last few chapters, Tom Sawyer is re-introduced and the reader is left to examine how different environments: sivilization and nature the river have affected the childrens growth. It is distinctly evident that Huck has turned out to be the one with a clear and intelligent mind, and Tom, although he can regurgitate worthless facts about Louis XVI and Henry VIII, shows no real sign of maturity. The first time I catched up to Tom, private, I asked him what was his idea, time of the evasion? Milton's multi-layered poem Lycidas is a literary work with a variety of interpretations and meanings EssayIt is apparent that Huck is overcoming the prevailing attitude of society regarding the justification of breaking up slave families. He is also beginning to see that Jim is more concerned about his children than Pap was about him. Jim is becoming less â€Å"black† and more human and thus begins to reveal to Huck that there is not so much difference between black and white. Also in this section we see Huck taking a stand to help someone else when he tells the girls that the â€Å"Duke and King† are not their uncles and devises a plan for them to be exposed. During this section, Huck took on the identity of being a slave owner when he first met the Duke and King and then later took on the identity of being a servant when the Duke and King set out to fool Mary Jane, Susan, and Joanna and steal their inheritance. These chapters deal with the very important and powerful issues that are alluded to early in the book. Huck is forced to decide between right and wrong concerning slavery when Jim is held by the Phelps. Deciding whether to help Jim or let him be returned to his rightful owner, Miss Watson, is a very powerful struggle with the morality of slavery. When Huck decides to help Jim even if it means going to hell, Huck has finally come to a decision. Huck assumes the identity of Tom Sawyer accidentally when he is mistaken for Tom by Aunt Sally and then together with Tom, who pretends to be Sid, the two of them plot Jim’s escape. The fact that Huck is willing to sacrifice his own soul for Jim’s sake shows the growth that Huck has undergone. This scene shows the change in the relationship between Huck and Jim from companion to friend to family. Huck makes his decision after remembering all the times that Jim protected and cared for him which not even his own family had done before. Once Tom is on the scene, Huck takes a backseat role. Huck is surprised that Tom is willing to steal a slave considering how long it took him to reach that decision. Later it is revealed that Tom already knew that Jim was actually freed so that his decision was not nearly as meaningful from a moral standpoint. Much of this section is a return to Tom’s humorous adventures and escapades as he contrives to free Jim in the most complicated manner. Huck reverts to his simple acceptance and minimization of his intelligence. The conclusion of the book is also the culmination of the struggle for freedom on two levels. Jim is revealed as a free man legally, having been freed by Miss Watson in her will. Jim’s struggles had not been necessary for him to be free but had been for the emotional growth of Huck and his freedom from society’s view of slavery. Huck is also revealed to be free from Pap as it is finally reported to him that his father was the dead person found on the river. The ending of the novel, however, finds Huck still in the same place of trying to escape civilization but Huck is no longer seen as the poor uneducated boy rather intelligent young man who does not want to be part of the middle class hypocrisy. The most profound change throughout the book is the view of Jim and thus of slavery. At first Jim is a background character as are all slaves, his importance as a human being surfaced throughout the book as well as the strength of his character. Through this change Twain sends a strong message about slavery to his reader.

Methods Of Recovering Energy From Waste An Environmental Sciences Essay Example

Methods Of Recovering Energy From Waste An Environmental Sciences Essay Biomass ( waste ) energy is progressively pulling attending worldwide because it is a renewable beginning of energy and potentially CO2 impersonal. At present, most waste stuffs are converted into electricity frequently by burning. Waste burning is widely applied for territory warming and combined heat and power for electricity coevals. This study describes waste, waste decrease and intervention ordinances in Europe every bit good as different types of waste generated, an overview of waste to energy engineerings applied throughout the universe today. Energy from waste has been evaluated based on their ability to cut down the emanation of pollutant into the ambiance. In order to extenuate clime alteration which is deriving increasing consciousness, recent developments of different engineerings that have been able to treat waste to bring forth heat and power with high efficiencies can be considered to be the most feasible option to replace fossil fuels. 2 Introduction Due to the lifting cost and the ecological disadvantages of fossil fuels, there as been concerns about the hereafter of energy supply in the universe. Harmonizing to the World Energy Council, dodo fuel covers about 82 % of the universe s energy. And this has caused terrible amendss for the environment in footings of nursery emanations, sea degree rise, air pollution, etc. Furthermore, as the World continues to see globalisation, rapid industrialisation and technological promotion, it will surely acquire to a point, where supply of these fossil fuels will non run into demand. Therefore, it is imperative to happen an alternate beginning of energy ( Soetaert and Vandamme, 2006 ) .

Biomass is a major beginning of biologically derived bio fuels ( bio-ethanol ) and biogas. This is well going a world in energy/electricity coevals. Biomass can be burnt straight to bring forth heat or electricity, or it can be converted into solid, liquid or gaseous fuel through agitation procedure into intoxicant and anaerobiotic digestion into biogas. There are many environmental and societal benefits associated with biomass energy. These include decrease in CO2 degrees, energy bearers to rural communities, waste control, etc. ( Calbe, Bajay, Rothman and Harry, 2000 ) . Biomass natural stuffs for energy coevals includes the first coevals feedstocks i.e. energy harvests ( maize, sugar cane, wheat, etc ) and the 2nd coevals feedstock chiefly lignocellulosic stuffs ( wood and agricultural residues ) . Hence, utilizing biomass as a replacement for fossil fuels is sustainable and good. However, there have been contentions on the usage of human nutrient ( energy harvest ) for energy coevals particularly in developing states where there is deficit of nutrient. Hoffert et Al. ( 2002 ) , Dismiss the usage of biomass for energy, others take the opposite position ( Dewulf and Langenhove 2006 ) . To this consequence, energy recovery from waste can be an economical feasible option. 3 Wastes 3.1 Definition Waste arises as a consequence of human technological development and societal activities. The Uk s Environmental Protection Act 1990 indicated waste includes any substance which constitutes a scrap stuff, an wastewater or other unwanted excess originating from the application of any procedure or any substance or article which requires to be disposed of which as been broken, worn out, contaminated or otherwise spoiled, this is supplemented with anything which is discarded otherwise dealt with as if it were waste shall be presumed to be waste unless the reverse is proved. Murphy et Al. ( 2002 ) defined waste as a stuff with no farther beneficial usage. The figure below shows the Conventional illustration of the EU Legal definition of waste 3.2 EU WASTE FRAMEWORK DIRECTIVE The Directive requires all Member States to take the necessary steps to guarantee that waste is recovered or disposed of without jeopardizing human wellness or doing injury to the environment and includes permitting, enrollment and review demands. The Directive besides requires Member States to take appropriate steps to promote foremost, the bar or decrease of waste production and its injuriousness and secondly the recovery of waste by agencies of recycling, re-use or renewal or any other procedure with a position to pull outing secondary natural stuffs, or the usage of waste as a beginning of energy ( Department for Environment, Food and Rural Affairs, 2009 ) . 3.3 UK WASTE MANAGEMENT POLICY The UK Waste Policy is developed from the thought of sustainable development. This policy promote recreation from landfills by enforcing high revenue enhancement levies on landfill site, cut down the sum of waste produced by the commercial sector, and finally promote re-use and recycling of stuffs. 3.4 WASTE HIERARCHY Figure 3.1 Waste hierarchy 3.5 TYPES OF WASTE Municipal Solid Waste Hazardous/Radioactive Waste Sewage Sludge Medical/Clinical Waste Agricultural Waste Industrial and Commercial Waste Other Waste e.g. building and destruction industry waste, mines and quarry waste and power station ash, Fe and steel scorias ( Williams, 1999 ) . There are besides two different sorts of component fraction in a waste watercourse ; The Organic fraction i.e. Biodegradable and the Inorganic fraction. 3.5.1Municipal Solid Waste This is composed of/includes chiefly household waste, with commercial and trade waste which is collected or disposed of by a municipality within an country. The composing of MSW watercourse varies, depending upon socio-economic factors, geographical locations, clime, population denseness and degree of industrialisation etc. for illustration in US and other industrialised states where value is placed on clip, consumers have adapted to the outlook of utilizing disposable at all times, thereby driving packaging and wrapping engineerings to a new degree, in add-on with the decayable waste from nutrient materials. The energy fraction contained in stuffs of this type of waste watercourse can be between 75 to 90 % . Whereas in less developed states where the waste watercourse is composed dominantly of decayable fraction i.e. groceries, veggie and organic stuffs with infinitesimal packaging stuffs, the energy content will be much lower ( Murphy, 2002 ) . Topographic point Sum OF MSW Kumasi, Ghana 365000 metric tons in 2006 China 180 million metric tons expected for 2010 United kingdom 34 million metric tons in 2007/2008 USA 190 million metric tons in 2009 Australia 43.8 million metric tons in 2006/2007 Ontario 267000 metric tons in 2007 Table 3.1 Average sum of MSW generated in different portion of the universe Data from Thermal Processing of Waste, J C Jones 2010 Fig 3.2 Municipal solid waste disposal tracts in US Data from US EIA 2010 3.5.2 Hazardous Waste Hazardous Waste is waste which contains substances that are considered to be unsafe to wellness and society. This includes substances which are reactive, infective, harmful, toxic and caustic etc. illustrations are chemicals such as, H nitrile, sulfuric acid, hydrofluoric acid etc. explosives such as dynamite, ammo etc. H2O reactive chemicals such as K, phosphoric, sodium hydride etc. In USA, estimate arisings of jeopardy waste is 275 million metric tons, UK 4.5 million metric tons, Germany 6 million metric tons, Spain 1.7 million metric tons ( Williams, 1999 ) . 3.5.3 SEWAGE SLUDGE Sewage Sludge is normally generated at the waste H2O intervention installation. It is a byproduct of the intervention of natural sewerage from domestic families, which may besides include commercial and industrial waste. The sewerage is composed chiefly of H2O, but after intervention, the wet stuff is concentrated to organize sewerage sludge ( Williams, 1999 ) . They are solid, semi-solid or bio solid in nature. Harper-Collins Dictionary of Environmental Science defines Sewage Sludge as a semi-solid mixture of bacteriums, virus-laden organic affair, toxic metals, man-made organic chemicals, and settled solids removed from domestic and industrial waste at sewerage intervention workss. ( Renewable Energy Institute ) The sewerage sludge intervention undergoes both aerophilic and anaerobiotic digestion and the concluding treated sewerage sludge is either land filled, spread on land as fertilisers or incinerated. Recent developments have shown that biogas can be produced during anaerobi otic digestion. 3.5.4 CLINICAL WASTE Clinical Waste is chiefly produced/waste originating from wellness Centres, infirmaries and nursing places etc. Examples include drugs, panpipes, acerate leafs, blood, human or carnal tissue etc. Approximately 0.3 1000000s metric tons of clinical waste arises in the UK yearly. Majority of clinical waste are incinerated ( Williams, 1999 ) . 3.5.5 AGRICULTURAL WASTE Agricultural waste is godforsaken watercourses by and large produced from agricultural activities. They are produced within agricultural premises and they include organic stuffs such as slurry, manure from farm animal, silage wastewater and harvest residues. It is estimated that about 700 million metric tons of agricultural waste is produced in OECD states. UK besides produces big tunnage, 80 million metric tons estimated from housed farm animal entirely ( Williams 1999 ) . 3.5.6 INDUSTRIAL AND COMMERCIAL WASTE These are types of waste watercourse that arises from both industrial and commercial sectors such as hotels and catering, nutrient, drink and baccy fabrication industries, metal fabrication industries, lumber and wooden furniture industries, mechanical and electrical industries, conveyance and communicating industries etc. The typical composing of this waste streams differs and really broad. A study carried out by Environmental Agency of some 4,500 commercial and industrial concerns in England in 2002/2003 showed that commercial waste amounted to 30 million metric tons and industrial waste 38 million metric tons ( meitnerium ) . In that study, the chief sectors bring forthing C A ; I wastes were retail ( 12.7mt ) , nutrient, drink and baccy ( 7.2mt ) , professional services and other ( 7.1mt ) , public-service corporations ( 6.2mt ) , the chemicals industries ( including fiber, gum elastic and plastics ) ( 5.3mt ) , basic metal industry ( 4.8mt ) and hotels/catering ( 3.4mt ) ( Defra, commercial and industrial waste in England, 2009 ) . 4 ENERGY RECOVERIES FROM WASTE TECHNOLOGIES Energy is recovered from waste either through thermic burning or biological/chemical reactions. The energy recovery procedure produces electricity straight through burning, or produces man-made and combustible fuel i.e. methane. 4.1 Incineration Incineration with energy recovery is the controlled burning of waste and it is the most broad spread waste to energy execution. It involves the burning of waste watercourses at high temperatures and the heat produced can be used to drive a turbine in order to bring forth electricity and territory warming. Waste stuffs or fuel are fed into incinerators in two ways, the mass fired/burning systems and decline derived fuel ( RDF ) fired systems. The mass firing involves minimum processing ; the full assorted municipal solid waste is fed into a furnace without any removal/separation of reclaimable and non combustible stuffs. For RDF fired engineerings, MSW undergoes pre-treatment, separation of non-combustible and reclaimable stuff which is known as RDF. RDF fired systems has a higher energy content compared to unrefined MSW because of its homogeneousness ( Tchobanoglous, Thiesen and Vigil, 1993 ) . There are assorted types of incinerator works design: moving grating, fixed grating, rotary-kiln, and fluidized bed incinerator. 4.1.1 Traveling Grate This can besides be called Municipal Solid Waste incinerators. The traveling grating enables the motion of waste by a waste Crane at one terminal of the grating through the burning chamber to the ash cavity at the lower terminal. The burning air is supplied through the grating prevarication below. Cooling of the grating itself is indispensable for the mechanical strength of the grating. One individual traveling grate boiler can manage 35 metric metric tons of waste per hr, and 8,000 hours per twelvemonth. 4.1.2 Fixed Grate This is a simpler type of incinerator. It is made of a brick lined compartment with a fixed metal grating above the lower ash cavity, with one gap for burden and another gap in the side for taking noncombustible solids known as cinders. 4.1.3 Rotary kiln It is largely used by municipalities and big industrial workss. Rotary kiln incinerators have 2 Chamberss, primary and secondary chamber. In the primary chamber, motion and transition of solid fraction of the waste to gases and partial burning occurs while the secondary chamber completes the gas stage burning reactions. 4.1.4 Fluidized Bed Fluidized Bed Combustion ( FBC ) is a burning engineering used in power workss. FBC developed from attempts to happen a burning procedure that is able to command pollutant emanations. Advanced fluidized bed burning offers a feasible power coevals technique. In fluidized bed burning, a strong air flow is forced through a sand bed, which keeps the waste suspended on wired air currents and takes on fluid like character. Due to the turbulent commixture, the waste and sand are to the full circulated through the furnace. 4.2 BALDOVIE WASTE TO ENERGY PLANT The Baldovie waste to energy works is a province of the art installation commissioned in Dundee in 1999, to replace a waste disposal incinerator due to its inability to run into EU demands on emanations. The works is run by a joint venture between Dundee metropolis council and private sector spouses. The joint venture is jointly called Dundee energy recycling limited ( DERL ) . The works processes 120,000 metric tons of waste yearly and generates electricity to run into its ain demand ( about 2.2MW ) and besides supply to the populace ( about 8.8MW ) . Separation techniques carried out before burning removes and recovers ferric metals which can be resold ( Gazetteer for Scotland, 2010 ) . 4.3 LANDFILL GAS CAPTURE Landfill is a waste disposal site where waste is deposited onto or into the land. When waste is deposited, it undergoes assorted debasement procedure which produces gas chiefly methane. Modern landfills have gas recovery systems, where the landfill gas is extracted and can be used for production of steam, heat and electricity ( Dewulf and Langenhove 2006, p.248 ) 4.4 ANAEROBIC DIGESTION Anaerobic intervention engineerings are used throughout the universe for effectual intervention of organic waste. This engineering is peculiarly attractive because the energy required for runing the procedure is minimum compared to energy required for aerophilic procedure. Anaerobic digestion is a complex biogenic procedure which involves the microbic debasement or transition of organic waste in a closed reactor vas ( absence of air ) to bring forth gas chiefly methane ( 55-65 % ) , CO2 ( 35-45 % ) , and hint sums of N2, H2 and H2S, depending on factors such as the composing of waste, organic burdens applied to the digester, clip and temperature. The methane-rich biogas which can be combusted to bring forth heat and electricity In general anaerobiotic digestion is considered to happen in three phases: A ] Liquefaction or polymer dislocation ; B ] Acid formation ; and C } Methane formation Substrates for anaerobiotic digestion includes waste H2O from nutrient processing, breweries, distilleries etc. sewerage sludge, carnal waste, farm residues. 4.5 GASIFICATION AND PYROLYSIS Gasification is defined as a partial oxidation/combustion of biomass and assorted combustible waste/carbonaceous fuels to bring forth gas. This gas can be used in internal burning engines and gas turbines to bring forth electric power. Pyrolysis is a thermic procedure which involves the dislocation of organic stuffs in waste under force per unit area in the absence of O. The pyrolysis procedure produces a liquid residue and gas which can be combusted to bring forth electricity. The chief difference between the two systems is that, pyrolysis system use an external beginning of heat to drive the endothermal pyrolysis reaction in an O free environment, whereas gasification systems are self-sustainable and utilize air or O for partial burning of solid province ( Tchobanoglous, Thiesen and vigil 1993 ) . 5 Decision Energy from waste has been evaluated based on their ability to cut down the emanation of pollutant into the ambiance, minimise waste, and generate heat and power. With the recent development of different engineerings that have been able to treat waste to bring forth energy with high efficiencies, waste to energy engineerings can be considered to be feasible substitute/option for fossil fuels for electricity coevals and besides in minimizing of waste accretion.

Spaying and Neutering

Spaying and Neutering Spaying and Neutering Spaying and Neutering By Maeve Maddox A local public service announcement invites listeners to telephone for further information â€Å"about spay and neutering.† A Web search finds numerous examples of the verb spay joined with the participle form: This vet clinic in SW Portland offers low-cost spay and neutering for cats and dogs. Pet Spay and Neutering Program–Just Fix It [USDA] provides a list of programs in each state that provides low cost or free spay and neutering services for cats. Several institutions and organizations offer help for pet spay and neutering or low-cost service.   The present participle of the verb spay is spaying. The examples should read â€Å"spaying and neutering†: This vet clinic in SW Portland offers low-cost spaying and neutering for cats and dogs. Pet Spaying and Neutering Program–Just Fix It [USDA] provides a list of programs in each state that provides low cost or free spaying and neutering services for cats. Several institutions and organizations offer help for pet spaying and neutering or low-cost service.   An easy way to avoid misusing the word spay in announcements of this kind would be to use only the word neuter. Unlike spay, which refers to the removal of an animal’s ovaries, the word neuter can mean either â€Å"to castrate† or â€Å"to spay.†    The past and present participle forms of the verb spay are frequently mispronounced and misspelled: Incorrect: I got my cat spaded and she got [a] hernia from the stitches. Correct : I got my cat spayed and she got [a] hernia from the stitches. Incorrect: I am contemplating  spading  and declawing my kitten when she turns 6 months old.   Correct : I am contemplating  spaying and declawing my kitten when she turns 6 months old. The past tense forms of both verbs–neuter and spay–end in -ed: neutered and spayed. The words are pronounced [nyoo-terd] or [noo-terd]) and [spayd]. Speakers who mispronounce and misspell the word spayed as spaded are perhaps confused by the existence of the word spade [spayd], which functions as both noun and verb. The verb spade (to dig) has a past form in -ed: If you did not plow or  spade the  garden site in the fall, turn the  soil  in spring as soon as it is dry enough to work. The Alcotts thrived as Bronson  spaded the  earth for his acre of garden. An interesting etymological fact is that both words–spay and spade–derive from spatha, the Latin word for a broad-bladed sword. The verb spay entered English from French espeier, â€Å"to cut with a sword.† Its earliest meaning in English was â€Å"to kill a deer with a sword,† as in these directions in a 1425 hunting manual: â€Å"spay him [the deer] even behind the shoulder forward to the heart.† The same manual also uses spay to mean removing the ovaries of an animal. The word spay got its name from the cutting aspect of a sword, whereas the word spade got its name from a sword’s tapered shape. It may help to keep the words spay and spade apart by remembering that animals are spayed with delicate medical instruments having no resemblance to broad garden implements.

Spaying and Neutering Spaying and Neutering Free Online Research Papers Rarely does one nod ones head in approval at the thought of surgically removing dogs or cats testicles. Removing the ovaries and uterus remains similarly unheralded except for when we clarify that we mean to chip away at the sexual organs of animals all for the sake of the expensive oriental rug that runs across the living room floor as luxuriously as a furry Fido or a purring Princess. Indeed in the back of our neighbors judgmental minds lurks the suspicion that we pet owners aim to spay our female animals or neuter our male creatures because of selfish human reasons. After all, not only may a female dog in heat ruin a rug, but also an intact dog is reportedly a threat to small children in the house. Granted, sparing one’s children is hardly deemed a selfish human desire, yet we still dismiss the fact that â€Å"the age of three is prime time for an intact male dog to be involved with a terrible tragedy, such as †¦ killing children† when we admit that â€Å"obviously, not all intact male dogs are aggressive child-killers† (Davis). In a fit of projection, we humans tend to personalize the medical matter of spaying and neutering, as if our own reproductive organs – let alone sex life and hunting skills – were on the line. But research shows that expert after expert believes that it is for the sake of the animal that we allow and perform these surgical procedures. Indeed, keeping an animal intact may be more selfish, for people who want to breed dogs or cats for show are typically those who oppose state-mandated neutering programs, which – together with educational programs- have been responsible for the fact that about 75 percent of d ogs and cats have been neutered or spayed (Woolf). With mostly competitive breeders and other extremists policing the privates of animals to keep them intact, a second look at the more humane reasons for these surgical procedures is certainly warranted. As the research shows, spaying and neutering are the single most effective methods of not only easing the strain on overpopulated shelters, but also for keeping cats and dogs healthy and safe. Overpopulation of cats and dogs lead to a burden on society. Animals reproduce at extremely high rates and may give birth to a large litter of newborns.
