How to Write a Paper on Global Warming

How to Write a Paper on Global Warming Writing a paper on global warming can be rather tricky task, as a lot of specific information is needed and certain peculiarities exist. We propose to your consideration an exemplary paper on this topic so as you can analyze it and write your own one on its basis. Nature and climate are in the constant evolution and change. In the majority of cases this transformation process is significantly slower, than the life expectancy of the generation. Therefore, we cannot evidence and observe how nature around us is evolving, unless we specifically address related literature and tools that help us to do so. It used to be this way till very recent past, but, more and more during the last decade we hear about the phenomena of global warming and its effects on our life. A lot of literature and TV programs introduce us in the latest changes in global climate and nature transformation, such as melting ice of the South and North Poles, average sea water level increase globally, etc. All these events are the causes for extinction of the various species and significant change in the geographical layout of particular areas. Temperature records are becoming common in different places of the world: Brazil is suffering from extreme winter, Russia is diving in high summer temperature and droughts, while Europe is drawing in everlasting rains. All these changes happened during five to ten years. For the first time in our planet’s history the humanity can evidence rapid changes that can be seen and experienced by one generation in full. What are the consequences of the global warming and what should we expect in the nearest future? We are not in control of the nature, but we undoubtedly one of the strongest elements of nature cycle, as each and every human activity has it reflection in the nature. It is high time time to re-evaluate and re-analyse the role of the humans in today’s environment and start turning our destructive activities into constructive cooperation.

Ethics And Morals Of Pi - 1181 Words

Mace 1 Megan Mace G. Cameron ENG 4U December 19, 2016 Ethics and Morals in Life of Pi Everybody; no matter your religion, skin colour, or gender possess a combination of morals based on the things internally believed are right or wrong. These can be established through many influences including, social constructs, personal experiences, and upbringing. Yann Martel is constantly challenging the reader’s morals throughout Life of Pi, after Pi is on the lifeboat, he has to make the extremely hard decision between his own religious morals, and survival. In all of Pi’s dilemmas, survival always outweighs the â€Å"needs† of mankind s culture, making these constructs no longer a priority. Utilitarianism, consequential versus categorical moral†¦show more content†¦You want a flat story. An immobile story. You want dry, yeastless factuality.† (Martel 336) Pi sees that the needs of a majority take precedence over the things that he went through --which could be reasonably contended-- so Pi tells them the story everyone would believe in the m eans to benefit society. Over many of years, the concept of utilitarianism has changed, people would once describe it as pain and pleasure. Now society begins to further the approach, thinking about the intensity and duration of pain and pleasure. To this day there are seven principles that should be considered while thinking about what true pain and pleasure are. Some including, intensity, duration, and propinquity or remoteness. Intensity, being one of the most important of all, can determine whether or not it is pain or pleasure, revealing a high degree of emotional excitement. The length of time something continues or exists, is known a duration. Propinquity or remoteness is the thinking of how close something is either in a time or location sense, as in when or where it is about to happen. These are all great morals to have, when it’s thought of in a utilitarian sense, it should be applied to a majority for it’s still the idea of equality.

The Future Of Fuel Cell Technology Engineering Essay Free Essays

In our current universe of planetary heating, clime alteration, fuel insecurity, and high energy demand and ingestion from developing states, it is perfectly necessary we started looking into how to bring forth the power of the hereafter. Through research, development, and promotion of engineering, several beginnings of alternate, clean renewable energy have been identified. One of the alternate beginnings of energy for the hereafter is â€Å" The Fuel Cell Technology † . We will write a custom essay sample on The Future Of Fuel Cell Technology Engineering Essay or any similar topic only for you Order Now This engineering ( fuel cell engineering ) has the possible to be the drift which will transform the manner in which industries of today will bring forth energy of tomorrow. Fuel Cell can merely be describe as a power bring forthing system made up of electrochemical cell that converts the chemical energy of H into electrical energy. The electrical energy is generated from the reaction between H ( which is the fuel ) an O ( which is the oxidizer ) . The history of fuel cells history can be dated back to 1939 when William Grove, a British scientist foremost discovered its rule. He demonstrated this by utilizing four big cells ( each incorporating H and O ) to bring forth electric power which was so used to divide the H2O ( in a smaller upper cell ) into H and O. The National Aeronautics and Space Administration ( NASA ) subsequently demonstrated their possible applications in supplying power during infinite flights. Since so, industry has been looking at the commercial viability of fuel cells engineering to bring forth energy in assorted applications in such a manner that it can vie with other sources/types of energy coevals. Fuel Cells Types There are several types of fuel cells being developed. The chief difference between fuel cells types is their electrolyte. The chief fuel cells types are listed below: Proton Exchange Membrane Fuel Cells ( PEMFC ) : This is besides called the Polymer Electrolyte Membrane Fuel Cell. It is the most favorable fuel cell engineering that offer alternate to the internal burning engine. The PEMFC uses a thin plastic membrane as its electrolyte. The reaction gases ( H and O ) are fed into the cell to respond with the anode and the cathode. The fuel H continuously flows to the anode. At the anode, H ions ( or protons ) and negatrons are produce from the H. Merely positively charged H ions pass through the membrane. The negatively charged negatrons flow to the electrical socket to bring forth electrical power. Oxygen continuously flow to the cathode. At the cathode the O combines with H ions and the negatrons to organize H2O which flows out of the cell. 2HA? a 4Ha + 4ea? » Equation for the reaction of the anode Oa‚‚ + 4Ha + 4ea? » a 2Ha‚‚O Equation for the reaction at the cathode 2Ha‚‚ + Oa‚‚ a 2Ha‚‚O Overall Equation Figure 1: How PEMFC works ( Beginning: hypertext transfer protocol: //altenergystation.com/fuel-cells.html ) The PEMFC has many advantages over all other types of fuel cell ; The PEMFC has a high power denseness and a low operating temperature ( of about 60-80 grades Celsius ) compared with other types of fuel cell. Its low operating temperature makes the fuel cell to warm up and get down bring forthing electricity within a short period of clip. Besides, the electrolyte is a solid stuff which makes it simpler to fabricate. The solid electrolyte of PEMFC makes it easier to orientate compared with other electrolytes. It is besides less caustic and has longer cell life and stack life. Other advantages of PEMFC are: It merely requires H and O as reactant. The by merchandise is H2O. It can be used as an option to internal burning engine. Although PEMFC has many benefits, it does hold some disadvantages excessively. The operating temperature is low ( about 80A °C ) ; which is non high plenty to execute utile cogeneration. It is an expensive signifier of electricity coevals. It cost about ?2500 – ?5000 per kilowatt. The control of wet in the cathode and anode watercourse is of import as the electrolyte is required to be saturated with H2O to run optimally. Direct Methanol Fuel Cells ( DMFC ) These types of fuel cells are comparable to the PEMFC except that methyl alcohol is used as fuel alternatively of H. It works by oxidising of the liquid methyl alcohol ( CHa‚?OH ) in the presence of H2O at the anode. The DMFC uses the same type of electrolyte as the PEMFC, but with thicker membranes. The chemical equation ( reaction ) of the DMFC is as follow ; At the anode: CHa‚?OH + Ha‚‚O a COa‚‚ +6Ha + 6ea? » At the cathode: 3/2Oa‚‚ + 6Ha + 6ea? » a 3Ha‚‚O Overall Equation: CHa‚?OH + 3/2Oa‚‚ a COa‚‚+ 2Ha‚‚O DMFC engineering is really applicable for portable power devices like laptops, 2-way wirelesss, cell phones, PDA etc. This is due to the high energy denseness of the methyl alcohol fuel. The current DMFCs can bring forth power denseness between 300-1000mWcmA? compared to PEMFC power denseness of 300-1000mWcmA? . DMFC can run between 50A °C and 120A °C with an efficiency of approximately 40 % . The DMFC offers a batch of benefits compared with PEMFC ; nevertheless its development is still in its early phases. Some of its advantages are ; It uses a liquid ( methyl alcohol ) fuel for power. Methanol can incorporate efficaciously with transmittal and distribution systems that are already in being. It does non necessitate a complicated fuel storage system, as suppose to hydrogen fuel storage for PEMFC. It is simpler in its design, and has the possible for low-volume, lightweight packaging. Methanol is easier to transport and provide in commercial measures utilizing current gasolene substructure. The chief disadvantage nevertheless, is that the low oxidation of methyl alcohol to hydrogen ions and COa‚‚ requires a more active accelerator. The fuel stack requires big measures of Pt compared with the PEMFC. Due to the big measures of Pt requires, the DMFC are more expensive. Other disadvantages are ; methanol is extremely caustic and toxic, DMFC have low efficiency compared to PEMFC due to the high pervasion of methyl alcohol through the membrane. Alkaline Fuel Cells ( AFC ) AFC were one of the first type of fuel cell engineerings developed and used in the United States infinite plan to bring forth electricity. AFC operates by utilizing a solution of K hydrated oxide ( KOH ) in H2O as the electrolyte. It can utilize a broad scope of assorted non-precious metals as a accelerator at the anode and the cathode. AFC operates at temperature between 100A °C and 250A °C, nevertheless, most recent design of AFC operate at lower temperature of approximately 23A °C to 70A °C. AFC have been proved to hold efficiency of stopping point to 60 % . Advantages of AFC are ; The costs of AFC are lowered compared to other signifiers of fuel cell engineerings because Alkaline engineering can work absolutely good without the usage of cherished metals. The AFC operates at a low temperature of about 70A °C. This lower its costs because the lower the operating temperature, the lower the cost of the stuffs needed to make a working and dependable system. AFC has the highest efficiency of all fuel cell type ( about 60 % ) . AFC nevertheless is susceptible to taint, hence requires pure H and O. Susceptibility of AFCs to taint besides affects the cell ‘s life-time, therefore extra cost. Phosphoric Acid Fuel Cells ( PAFC ) The PAFC is one of the modern fuel cell and the first to be used commercially. PAFC can bring forth up to 200 kilowatt of power and is chiefly used to power stationary power coevals and besides to power big vehicles like coachs. The PAFC uses liquid phosphorous acid as an electrolyte. The phosphorous acid is contained in a Teflon-bonded Si carbide matrix and porous C electrodes incorporating a Pt accelerator. The chief feature of PAFC is the impregnation of the phosphorous acid aqueous solution as the electrolyte in the matrix. The efficiency of PAFC is approximately 40 % but can be increased to over 70 % with combined heat and power. One of the chief advantages of PAFC is that they are more receptive to drosss in fossil fuels that have been reformed into H than PEMFC, which are easy poisoned by C monoxide. PAFC are besides more efficient when used for the cogeneration of electricity and heat ( about 85 % ) . Other benefit of PAFC is its first-class dependability and long-run public presentation. The disadvantage nevertheless is that it takes longer to warm up because it operates at a higher temperature ( between 150A °C and 200A °C ) , therefore doing it unsuitable for usage in autos. It besides requires Pt as a accelerator like most other types of fuel cells, but provides low power and current. Another deficit of PAFC is its size and volume in relation to their end product compared with other types of fuel cell.

Romeo And Juliet Essays (946 words) - Characters In Romeo And Juliet

Romeo And Juliet Romeo and Juliet, said to be one of the most famous love stories of all times, is a play anchored on time and fate. Some actions are believed to occur by chance or by destiny. The timing of each action influences the outcome of the play. While some events are of less significance, some are crucial to the development of this tragedy. The substantial events that inspire the conclusion of Romeo and Juliet are; the Capulet ball, the quarrel experienced by Tybalt and Romeo, and Friar Johns plague. A servant to Capulet, who is incapable of reading the list of guests, asks for Romeos assistance. Romeo notices that Rosaline, his lover, is among these names. Benvolio challenges Romeo to compare her with other beauties. Benvolio predicts, Compare her face with some that I shall show,/ And I will make thee think thy swan a crow. (I, ii, l 86-87) To show his appreciation, the servant asks for Romeos presence at the ball. Romeo should have considered the servants warning; if Romeo occupies the name of Montague, he shall not be permitted. Once at the ball, Romeo is searching for a maiden to substitute the unrequited love of Rosaline. Romeo happens to gaze upon Juliet, who charms Romeo. Romeo proclaims, Did my heart love till now? Forswear it, sight!/ For neer saw true beauty till this night. (I, v, l 52-53) Since Romeo declares his love for Juliet, she feels the attraction also. They believe that they are in love and must marry. However, it is a genuine coincidence that Romeo and Juliet were at the same place, at the same time. Some days after the ball, Benvolio and Mercutio are conversing, in regard to the quarrelsome weather. Benvolio declares, The day is hot, the Capulets abroad,/ And if we meet we shall not scape a brawl,/ For now these got days is the mad blood stirring. (III, i, l 2-4) At this point, Tybalt, who has challenged Romeo because of his appearance at the masquerade, enters, seeking Romeo. On Romeos behalf, Mercutio struggles with Tybalt, while Romeo, who is filled with love for his new cousin, tries to end their boldness. Before escaping, Tybalt plunges his sword into Mercutio, causing death to fall upon him. Mercutio blames Romeo and the feud for his fate. Romeo kills Tybalt, who taunts Romeo, upon his return. Romeo fears he will be condemned to death if he does not flee before the arrival of the Prince. Benvolio recalls the events that have happened, with some embellishment. The Prince declares: And for that offence/ Immediately we do exile him hence./ I hav an in your hates proceeding,/ My blood for your rude brawls doth lie a-bleeding;/ But Ill amerce you with so strong a fine/ That you shall repent the loss of mine./ I will be deaf to pleading and excuses;/ Nor tears nor prayers shall purchase out abuses;/ Therefore use none. Let Romeo hence in haste,/ Else, when hes found, that hour is his last./ Bear hence this body and attend our will./ Mercy but murders, pardoning those that kill. (III, i, l 185-195) Due to the disturbance of Veronas street and the losses of Tybalt and Mercutio, the Prince must penalize Romeo. However, the Prince agrees that Romeo was acting in self defense. Juliet, who desires not to wed Paris, asks for Friar Laurences assistance. The day before the wedding, Juliet is to drink the poison, which will make her appear to be dead. In forty two hours she shall awake, with Romeo by her side. Romeo will then bring her to Mantua with him. In the meantime Friar Laurence will convey a message to Romeo in Mantua, telling him the plot. When she gains consciousness, Romeo and Friar Laurence will be there. Friar Laurence says, Shall Romeo by my letters know our drift,/ And hither shall he come; and he and I/ Will watch thy waking (IV, i, l 114-116) Following Juliets intake of the poison, Romeo is anticipating news from Verona. Balthasar, a servant to Romeo, tells Romeo that Juliet has passed on. Romeo, who is told there are no letters from the friar, seeks a way to accomplish his

Anton Chekhov - Biography and Profile

Anton Chekhov - Biography and Profile Born in 1860, Anton Chekhov grew up in the Russian town of Taganrog. He spent much of his childhood quietly sitting in his fathers fledgling grocery store. He watched the customers and listened to the their gossip, their hopes, and their complaints. Early on, he learned to observe the everyday lives of humans. His ability to listen would become one of his most valuable skills as a storyteller. Chekhovs YouthHis father, Paul Chekhov, grew up in an impoverished family. Antons grandfather was actually a serf in Czarist Russia, but through hard work and thriftiness, he purchased his familys freedom. Young Antons father became a self-employed grocer, but the business never prospered and eventually fell apart. Monetary woes dominated Chekhovs childhood. As a result, financial conflicts are prominent in his plays and fiction. Despite economic hardship, Chekhov was a talented student. In 1879, he left Taganrog to attend medical school in Moscow. At this time, he felt the pressure of being the head of the household. His father was no longer earning a living. Chekhov needed a way to make money without abandoning school. Writing stories provided a solution. He began writing humorous stories for local newspapers and journals. At first the stories paid very little. However, Chekhov was a quick and prolific humorist. By the time he was in his forth year of medical school, he had caught the attention of several editors. By 1883, his stories were earning him not only money but notoriety. Chekhovs Literary PurposeAs a writer, Chekhov did not subscribe to a particular religion or political affiliation. He wanted to satirize not preach. At the time, artists and scholars debated the purpose of literature. Some felt that literature should offer life instructions. Others felt that art should simply exist to please. For the most part, Chekhov agreed with the latter view. The artist must be, not the judge of his characters and of what they say, but merely a dispassionate observer. Anton Chekhov Chekhov the PlaywrightBecause of his fondness for dialogue, Chekhov felt drawn to the theatre. His early plays such as Ivanov and The Wood Demon artistically dissatisfied him. In 1895 he began working on a rather original theatrical project: The Seagull. It was a play that defied many of the traditional elements of common stage productions. It lacked plot and it focused on many interesting yet emotionally static characters. In 1896 The Seagull received a disastrous response on opening night. The audience actually booed during the first act. Fortunately, innovative directors Konstantin Stanislavski and Vladimir Nemirovich-Danechenko believed in Chekhovs work. Their new approach to drama invigorated audiences. The Moscow Art Theatre restaged The Seagull and created a triumphant crowd-pleaser. Soon after, the Moscow Art Theatre, led by Stanislavski and Nemirovich-Danechenko, produced the rest of Chekhovs masterpieces: Uncle Vanya (1899) The Three Sisters (1900) The Cherry Orchard (1904) Chekhovs Love LifeThe Russian storyteller played with themes of romance and marriage, but throughout most of his life he did not take love seriously. He had occasional affairs, but he did not fall in love until he met Olga Knipper, an up-and-coming Russian actress. They were very discreetly married in 1901. Olga not only starred in Chekhovs plays, she also deeply understood them. More than anyone in Chekhovs circle, she interpreted the subtle meanings within the plays. For example, Stanislavski thought The Cherry Orchard was a tragedy of Russian life. Olga instead knew that Chekhov intended it to be a gay comedy, one that almost touched upon farce. Olga and Chekhov were kindred spirits, though they did not spend much time together. Their letters indicate that they were very affectionate to one another. Sadly, their marriage would not last very long, due to Chekhovs failing health. Chekhovs Final DaysAt the age of 24, Chekhov began showing signs of tuberculosis. He tried to ignore this condition; however by his early 30s his health had deterorated beyond denial. When The Cherry Orchard opened in 1904, tuberculosis had ravaged his lungs. His body was visibly weakened. Most of his friends and family knew the end was near. Opening night of The Cherry Orchard became a tribute filled with speeches and heartfelt thanks. It was their was of saying goodbye to Russias greatest playwright. On July 14th, 1904, Chekhov stayed up late working on yet another short story. After going to bed, he suddenly awoke and summoned a doctor. The physician could do nothing for him but offer a glass of champagne. Reportedly, his final words were, Its a long time since I drank champagne. Then, after drinking the beverage, he died Chekhovs LegacyDuring and after his lifetime, Anton Chekhov was adored throughout Russia. Aside from his beloved stories and plays, he is also remembered as a humanitarian and a philanthropist. While living in the country, he often attended to the medical needs of the local peasants. Also, he was renowned for sponsoring local writers and medical students. His literary work has been embraced throughout the world. While many playwrights create intense, life-or-death scenarios, Chekhovs plays offer everyday conversations. Readers cherish his extraordinary insight into the lives of the ordinary.

Hurricane Etymology

Hurricane Etymology Unlike most words that Spanish and English share because of their shared history with Latin, hurricane came to English directly from Spanish, where it is currently spelled huracn. But Spanish explorers and conquerers first picked up the word from Taino, an Arawak language from the Caribbean. According to most authorities, the Taino word huracan meant simply storm, although some less reliable sources indicate that it also referred to a storm god or an evil spirit. This word was a natural one for the Spanish explorers and conquerors to pick up from the indigenous population, since winds as strong as the hurricanes of the Caribbean were an unusual weather phenomenon for them. Use of ‘Hurricane’ and Huracn The fact that the Spaniards introduced the word to the English language is the reason that our word hurricane generally refers to tropical cyclones that have their origin in the Caribbean or Atlantic. When the same type of storm has its origin in the Pacific, it is known as a typhoon (originally a Greek word), or  tifà ³n  in Spanish. There is a slight difference in the way the storms are categorized in the languages, however. In Spanish, a  tifà ³n  generally is considered to be a  huracn  that forms in the Pacific, while in English hurricane and typhoon are considered to be separate types of storms, even though the only difference is where they form. In both languages, the word can be used to refer figuratively to anything that is powerful and causes turmoil. In Spanish,  huracn  can also be used to refer to a particularly impetuous person. At the time the Spanish language adopted this word, the h was pronounced (it is silent now) and was sometimes used interchangeably with f. So the same word in Portuguese became furaco, and in the late 1500s the English word was sometimes spelled forcane. Numerous other spellings were used until the word was firmly established at the end of the 16th century; Shakespeare used the spelling of hurricano to refer to a waterspout. The word huracn is not capitalized  when referring to named storms. It is used as in this sentence: El huracn Ana trajo lluvias intensas. (Hurricane Ana brought heavy rains.) Other Spanish Weather Terms in English Hurricane isnt the only Spanish weather term that has found its way into English. The most common of them, tornado, is especially interesting because of the way the two languages played off each other. The Strange Story of ‘Tornado’ and Tornado Although English got its word tornado from Spanish, Spanish surprisingly got its word tornado from English. Thats because the Spanish word that English borrowed wasnt tornado but tronada, a word for a thunderstorm. As is common in etymology, words often change form when imported into another language. According to the Online Etymology Dictionary, the change of -ro- to -or- was influenced by the spelling of tornar, a Spanish verb meaning to turn. Although tornado in English originally referred to various types of whirlwinds or rotary storms, including hurricanes, in the United States the word eventually came to refer primarily to a type of funneled windstorm common in the U.S. Midwest. In modern Spanish, tornado, borrowed from English, can still refer to various kinds of storms and whirlwinds, including hurricanes. A windstorm on the scale of a tornado, or smaller such as a whirlwind, can also be called a torbellino. Derecho Another type of storm phenomenon is known as a derecho, a direct borrowing of the Spanish derecho, which can, confusingly to foreigners, mean either right (as an adjective) or straight. In this context, it is the second meaning that matters. A derecho refers to a cluster of thunderstorms that travels in a straight line and is capable of causing great destruction. According to the Online Etymology Dictionary, Gustavus Hinrichs of the Iowa Weather Service started using the term in the late 1800s to avoid confusing a certain type of storm system with tornadoes. Key Takeaways The English word hurricane started out as an indigenous Caribbean terms that was adopted into Spanish and then spread to English via Spanish explorers and conquerors.Because the word hurricane came from the Caribbean, a different term is used for the same type of storm when occurring in the Pacific Ocean.The weather terms tornado and derecho also come from Spanish.

Quantitative and Qualitative Research Methods Essay

Quantitative and Qualitative Research Methods - Essay Example Broadly, research methods are divided into two categories namely quantitative research method and qualitative research method. Both are different in nature and have different applicability. Both the methods find their applications in different disciplines and have strengths and shortcomings in various domains. There are certain pre requisites that apply to each of them and each of them underlines a specific method of implementation. Qualitative research method: This method of research is subjective in nature which mostly contains case studies, interviews, unlike quantitative methods the outcomes are in textual form and not in digits and statistical values. Questions like why, where when who are touched upon by this type of research method. Qualitative approach is scientific in nature and may not have a fixed deterministic solution by end of research conducted. Such research can be helpful in studying the behaviors, approach, their fears and concerns including natural response, dealin g with opinions and possibly culture oriented issues. While quantitative research provides fixed results, their counterpart lay foundation for the study and research beyond the point where the scope of quantitative research ends. Such research approaches are inductive in nature and the mode of language used is informal .Furthermore, qualitative research is most suited to the initial stages (Merriam, 2009). The tools and techniques that might be used during qualitative approach can possibly include memos, interviews, artifacts, picture or any piece of video (Pitney & Parker,pg53, 2009) . Stressing on the importance of qualitative approach Donald Campbell stated that â€Å"All research ultimately has a qualitative grounding† (Farrell, pg8, 2011). Characteristic feature of such an approach is its ability to address the intangible aspects of society and human nature. Lincoln defines qualitative research as interpretive and naturalistic in nature (Flick,pg2, 2007). Three broad typ es of qualitative research encompass Case studies: while adopting case studies for purpose of research, focus is concentrated on an individual phenomena and concept that are constrained by duration and activities. Various data collection procedures are adopted during the case study approach. Phenomenological studies: In such approach attempt is being made to get the response of people based on their personal experience about a particular instance and event, intensive research is being carried out number of times through the aide of detailed elaborations Ethnographic studies: As the name implies, the focus of research in this category is a particular group of individuals that are involved in a similar kind of task.
