The Ideology Of Overcoming Inequality - 1681 Words

The ideology of overcoming inequality can be very complex in which many people around the world still suffer from social inequality today. Although this issue has been around for many years, through the support from social welfare agencies, human service organizations and working together as a community assists on constructing a much healthier and stable society for individuals to live in. Social agencies and human service organizations occur so that services and resources of our social welfare system can be distributed to people in need. The concept of a social agency can be a private or government run organization that have locations purposes set out in the form of mission and policy statements and programs designed to provide services to defined groups of clients. It is â€Å"a structured unit, sanctioned by society, whose goals and activities focus on meeting human needs† (Turner, 209). Majority of social agencies are considered to be primary social work settings in which is known to have professional social workers. With human service organizations, they are recognized as secondary settings for social work practice such as hospitals, schools, government departments; as these human service organizations employ social workers. Without out the help and support from social agencies and human service organizations, it is difficult to visualize Canadian society without them as their existence offers individuals human spirit that moves us to care for strangers’ well-being.

Essay on Success You can do it! - 1084 Words

You can do it! -SUCCESS- Success is to fulfil a goal that you have set for yourself. Achievement of success involves five components: realisation, confidence, motivation, action and perseverance. Step one is to realise your goal and how to achieve it. Step two is to have the confidence to take the steps towards your goal. Step three is to find motivation to keep you on the path towards you goal. Step four is action, the first physical step you take in the process for success. Step five is perseverance. On the road to success, you will most definitely come to setbacks and struggles. The only way to conquer those things and achieve your goal is to have strong perseverance. As David Brink said, quot;A successful person is one who†¦show more content†¦Without that fuel, you will go nowhere. Motivation can be a number of things. It could be family, money, fame, fear of failure; anything that makes you strive for your goal. My motivations are to: become famous, be able to live comfortably, and to be able to raise a family. I will hold onto these things and will keep moving towards success. Nelson struggled with his motivation, â€Å"I felt impressed with a feeling that I should never rise in my profession. My mind was staggered with the view of the difficulties I had to surmount and the little interest [influential friends] I possessed. I could discover no means of reaching the object of my ambition. After a long and gloomy reverie in which I almost wished myself overboard, a sudden glow of patriotism was kindled within me and presented my king and country as my patron. ‘Well then,’ I exclaimed, ‘I will be a hero and confiding in providence I will brave every danger.’† He found his motivation to be patriotism to his country to be known as a hero. Step 4 – Action Action is the first physical step you will take in success. Action is bringing together realisation, confidence and motivation. This is when all your planning comes together you start actually doing the things you need to get to your goal: putting your plan into action. I got into a group where we film rock concerts.

Particle in a Box Experiment Essay Example

Particle in a Box Experiment Essay The visible absorption bands or conjugated dye arise from electron transitions involving the electrons in the conjugated and they are free to move along the chain and are not attached to any atom. An example of such a dye is 3,3-diethyl-thiacyanine iodide. The cation has two resonance forms causing each of the bonds in the conjugated chain to have an order of 1. 5 and have a length similar to the C? C bond length in benzene. We will assume that the potential energy is constant along the chain and sharply rises to infinity at the ends.Therefore, we can replace the electron system by free electrons moving in a one dimensional box of length . Objective: The purpose of this experiment is to obtain the visible spectra of several cyanine dyes and then interpret them to a simple model of the electronic structure of the ? system: the Particle in a Box. Theoretical Model â€Å"Particle in a Box† In the Particle in a Box model, all potential energy interactions are assumed to be zero (c onstant) along the chain except at ends of the chain where the potential energy abruptly goes to +?. If a particle moving freely along the length of the box the energy an be calculated as : E = n2h28mL2 + V n = 1, 2, 3 †¦ (1) where n is an integer positive quantum number, h is Planck’s constant, m is the mass of the particle and L is the length of the box. If we assume that the most intense band in the experimentally observed spectrum can be interpreted as absorption of electromagnetic radiation by an electron as it is promoted from the HOMO to the LUMO, we can derive the following expression for the energy absorption ? E. E =h2 [2ni+ 1]/ (8mL? ) (2) he absorption wavelength for the HOMO _ LUMO transition is given by: ? = 8mcL? /h (2ni + 1) ni = p p = #e/2 (3) Therefore, the Particle in a Box model predicts that the wavelength of the absorption maximum is a function of chain length (L) and number of p-electrons (N). The adjustable parameter Lmax can be calculated as: ? = 8mc/h(2p+1)[(2p-1)Lb + Lext]2 (4) ?max h/8mc=[2p-1Lb + Lext ]2/ (2p +1) (5) Procedure: In this experiment, we used the following dyes. Dye #1: 3,3-diethyl-thiacyanine iodide (yellow) Dye #2: 3,3-diethylthiacarbocyanine iodide (Pink)Dye #3: 3,3-diethylthiadicarbocyanine iodide (Blue) Dye #4: 3,3-diethylthiatricarbocyanine iodide (Olive) We placed 0. 3 ml of dye solution in the 1- cm cuvette and added 3. 00 ml of water and mixed well. Using the nano drop spectrometer, first cuvette with water was used as a blank and later second Cuvette with dye solution was inserted and measured the absorbance of the sample. Once our absorbance of the highest peak was less than 0. 5 and the absorption spectrum of each dye was between 400-800 we collected the data. Notes On Wavelength:If only changes in electronic energy accompany absorption of light, a very sharp maximum in absorption should be observed at the characteristic wavelength. Although sharp lines are observed for isolated atoms, broad ab sorption bands are observed for substances in liquid phases (due to the accompanying vibrational and rotational transitions). In the experiment, we shall assume that the wavelength ? max, the wavelength at which the dyes absorb most strongly, is the wavelength to use in the equation (5). Data/Result: A UV-Vis absorbance spectrum (Fig 1) was obtained and used to calculate experimental ? ax values for each of the studied cyanine dyes. Fig 1: UV Absorbance Spectrum for Dye 5d, Dye 6, Dye7 and Dye 8b Collected from Nanodrop Based on the data: Dye | Emprical formula | ? max /nm | Lit ? max| 3,3-Diethylthiacyanine Iodide| C19H19IN2S2| 417| 423| 3,3-Diethylthiacarbocyanine Iodide| C21H21IN2S2| 549| 556| 3,3-Diethylthiadicarbocyanine Iodide| C23H23IN2S2| 564| 652| 3,3-Diethylthiatricarbocyanine Iodide| C25H25IN2S2| 744| 757| In order to experimentally to calculate the Lext a plot of h ? 8mc experimental bond length, and P the number of the c atoms in conjugated system (N / 2) was constructe d.

This can be due to the electronic transitions from state to state which occur within a time interval much shorter than that of a molecular vibration and also experimental error was responsible for the lack of resolution.The collected electrically spectra were useful in comparison of experimentally and theoretically predicted ? max values and it shows that the experimentally determined values are close to the predicted value. Extracting Lext from equation (5) for each dye doesn’t follow the observed trend in the absorption maxima. For 3,3-Diethylthiacyanine Iodide and 3,3-Diethylthiacarbocyanine Iodide dyes as ni increases Lext and ? max increases and in 3,3-Diethylthiadicarbocyanine Iodide and 3,3-Diethylthiatricarbocyanine Iodide, Lext decreases as ni increases. The experimentally calculated Lext for compounds 1-4 was determined to be 6. 2E-5 m which doesn’t seem sensible. Large differences existed difference between the calculated effective box length compare to lb. From the experimental evidence and analysis, we don’t except the particle in a box model to be an appropriate one to describe the spectra of cyanine dyes. Since the errors in the ? max are not normally distributed experimental errors.Work Citedhttp://homepages. gac. edu/~anienow/CHE-372/Labs/Example. pdf http://homepages. gac. edu/~anienow/CHE-372a/Labs/Conjugated%20Dyesa. pdf

Visa J-1 para estudiar la especialidad médica en USA

Visa J-1 para estudiar la especialidad mà ©dica en USA La visa J-1 permite a los mà ©dicos extranjeros graduados en facultades de medicina fuera de Canad y de Estados Unidos estudiar sus residencias o especializaciones en este à ºltimo paà ­s.   Asimismo, esta visa permite a los mà ©dicos de otros paà ­ses ingresar a Estados Unidos para realizar investigacià ³n avanzada en el mbito de la medicina. Es decir, permite adquirir conocimientos clà ­nicos y no clà ­nicos y esta diferenciacià ³n es muy importante como se ver ms adelante en relacià ³n a la regla de los dos aà ±os. Este artà ­culo explica los requisitos fundamentales para participar en este programa de visa J-1 para alien physician. Por ejemplo, quià ©n puede ser patrocinador,   requisitos de certificacià ³n y para solicitar la visa, cambios de especializacià ³n, cà ³mo llevar a la familia y, por à ºltimo, la famosa regla de los dos aà ±os y cundo no aplica o es posible pedir una excepcià ³n. Finalmente, no confundir con el programa distinto de trainee o prcticas  con visa J-1, en el que tambià ©n pueden participar mà ©dicos, ya que las reglas son distintas. Patrocinador de mà ©dicos para la visa J-1 para especialidad o residencia La Comisià ³n Educativa para Graduados Mà ©dicos Extranjeros (ECFMG, por sus siglas en inglà ©s) es el à ºnico patrocinador reconocido por el gobierno de los Estados Unidos. Y es que de entre todas las visas no inmigrante con las que es posible viajar a Estados Unidos, las J-1 de intercambio tienen, entre sus requisitos, la necesidad de contar con un patrocinador, tambià ©n conocido como esponsorizador, que tiene que estar reconocido oficialmente.   Certificacià ³n de los estudios realizados por los mà ©dicos extranjeros Antes de solicitar la visa, la ECFMG tiene que certificar que el mà ©dico extranjero interesado en una visa J-1 est preparado para participar en un programa de especializacià ³n o investigacià ³n en Estados Unidos. El proceso de certificacià ³n es largo y complejo. Entre los requisitos, ser necesario demostrar los conocimientos mà ©dicos y tambià ©n un alto nivel de inglà ©s, tanto oral como escrito, que se mide mediante los resultados obtenidos en un examen conocido como TOEFL. Tambià ©n es imprescindible aprobar una de las siguientes pruebas: Partes I y II del National Board of Medical Examiners Examinationel Foreign Medical Graduate Examination, Step I y Step IIo el Visa Qualifying Examination (VQE) Todas esas pruebas son gestionadas por ECFMG. Requisitos para solicitar la visa J-1 para mà ©dicos subcategorà ­a alien physician Una vez obtenidos el certificado de la ECFMG y otros requisitos, esta organizacià ³n emite un documento conocido como DS-2919.   Tambià ©n es necesario una declaracià ³n por escrito del gobierno del paà ­s en el que reside el mà ©dico extranjero en el que se afirma que hay una necesidad en dicho paà ­s de doctores especializados en la rama que la que se va a buscar la especializacià ³n. Asimismo, se necesita un contrato u oferta de la institucià ³n en la que se ha sido admitido para realizar la especializacià ³n. Los candidatos extranjeros y los ciudadanos estadounidenses que estudiaron Medicina fuera de EEUU son considerados IMGs. Sus oportunidades durante el proceso que se conoce como Match para ligar candidato con institucià ³n acadà ©mica/hospital son generalmente no tan buenas como las de los graduados en facultades de Estados Unidos, por lo que se recomienda venderse agresivamente con los directores de los programas que interesan para levantar cualquier sospecha que pueda recaer sobre la calidad de sus estudios previos. Una vez que se tienen todos los pasos previos completados, ya se puede solicitar la visa J-1, lo cual se hace en là ­nea completando el formulario DS-160. El tiempo de tramitacià ³n depende del consulado o embajada y tambià ©n de las circunstancias personales del solicitante. Como parte de la tramitacià ³n es necesario pagar la cuota, que no se recupera si la visa no es aprobada. Tambià ©n se pasa por una entrevista en el consulado o embajada y en algà ºn momento del proceso, que varà ­a segà ºn la ubicacià ³n, se tomarn las huellas digitales del solicitante y una foto. Como en todo tipo de visas no inmigrante, las razones por las que puede haber un rechazo de la negacià ³n son muchas, distinguià ©ndose causas que convierten a una persona en inelegible y aquellas que lo convierten en inadmisible.   Si bien en la mayorà ­a de los casos el problema puede surgir porque el candidato no demuestra suficientemente que su intencià ³n no es quedarse en Estados Unidos. Es muy importante poder probar que se va a regresar al paà ­s de origen. Aunque no hay reglas expresas sobre quà © documentos utilizar, es de gran ayuda seguir las reglas generales que se utilizan para este fin cuando se solicita una visa de turista. Visas para familiares para mà ©dicos realizando la residencia en Estados Unidos El cà ³nyuge del solicitante de la visa J-1 y sus hijos solteros que son menores de 21 aà ±os pueden acompaà ±ar al mà ©dico a Estados Unidos. Su visa es una J-2, de dependiente. Para poder solicitarla es necesario solicitar a ECFMG que extienda el patrocinio a estos familiares. Trabajar en Estados Unidos   La finalidad del mà ©dico es especializarse. Para ello obviamente debe realizar prcticas en su campo, por las que ser compensado econà ³micamente. Sin embargo, lo que no puede hacer y est estrictamente prohibido es trabajar fuera del programa. Hacer tal cosa es una violacià ³n migratoria que puede provocar la cancelacià ³n de la visa. Cambios de especialidad mà ©dica Si el mà ©dico con una visa J-1 inicia una especializacià ³n y cambia de parecer y decide que prefiera otra, puede tramitar un cambio de la misma siempre y cuando todavà ­a no tenga completado el segundo aà ±o de la especializacià ³n.   Una vez iniciado el tercer aà ±o ya no es posible ese tipo de cambios. La regla de los dos aà ±os de permanencia fuera de EEUU En principio, los mà ©dicos que participan en un programa J-1 dentro de la categorà ­a de alien physician deben salir de Estados Unidos por dos aà ±os y residir en otro paà ­s durante ese tiempo. Esto NO quiere decir que no puedan viajar a USA   como turistas, quiere decir que no pueden obtener una visa de trabajo de la familia H o de la L o una green card. Esto afecta incluso a las personas casadas de buena fe con un ciudadano americano. En principio, les aplica esa regla. Pero hay excepciones. Por ejemplo, no aplica a los mà ©dicos cuya labor en los Estados Unidos fuera de investigacià ³n, observacià ³n o enseà ±anza y no tuvieran un contacto directo con pacientes. Adems, es posible pedir un permiso conocido como waiver para que no aplica esa regla.

Biography of James Watt, Modern Steam Engine Inventor

Biography of James Watt, Modern Steam Engine Inventor James Watt (January 19, 1736–August 25, 1819) was a Scottish inventor, engineer, and chemist. He developed a workable steam engine that utilized a separate condenser; this innovation made the steam engine a useful tool for a vast range of uses. In many ways, Watts invention- or rather, his improvement on an earlier invention, the Newcomen steam engine- was the technological impetus behind the Industrial Revolution. Fast Facts: James Watt Known For: Invention of the steam engineBorn: January 19, 1736 in Greenock,  Renfrewshire, Scotland, United KingdomParents: Thomas Watt, Agnes MuirheadDied: August 25, 1819 in  Handsworth, Birmingham, England, United KingdomEducation: Home educatedPublished Works:  A System of Mechanical PhilosophyAwards and Honors: Many streets and schools carry his name; statues of his likeness in Picadilly Gardens and St. Pauls CathedralSpouse(s): Margaret (Peggy) Miller, Ann MacGregorChildren: James Jr., Margaret, Gregory, Janet, AnnNotable Quote: I had gone to take a walk on a fine Sabbath afternoon. I had entered the Green by the gate at the foot of Charlotte  Street and had passed the old washing house. I was thinking upon the engine at the time, and had gone as far as the herds house, when the idea came into my mind...I had not walked  farther  than the Golf  house when the whole thing was arranged in my mind. Early Life James Watt was born on January 19, 1736, in Greenock, Scotland, as the only surviving child of four of James Watt (1699–1737) and Agnes Muirhead (1901–1754). Greenock was a fishing village that during Watts lifetime became a busy town with a fleet of steamships. James Jr.s grandfather Thomas Watt (1642–1734) was a well-known mathematician and local schoolmaster. James Sr. was a prominent citizen of Greenock and a successful carpenter and ships chandler who worked at outfitting ships and working on their instruments, compasses, and quadrants. At various times, James Sr. was also the chief magistrate and treasurer of the town. Education James Watt was intelligent, but because of poor health he was unable to attend school regularly. Instead, he gained the skills he would later need in engineering and tooling by working with his father on carpentry projects. By age 6, James Watt was solving geometrical problems and conducting his earliest investigation into the nature of steam, which involved experimenting with his mothers tea kettle. In boyhood, Watt was an avid reader and found something to interest him in every book that came into his hands. When Watt was finally sent to the village school, his ill health prevented his making rapid progress; it was only when he was 13 or 14 that he began to exhibit his abilities, particularly in mathematics. His spare time was spent sketching with his pencil, carving, and working at the tool bench with wood and metal. He made many ingenious mechanical works and some beautiful models, and enjoyed repairing nautical instruments. Apprenticeship After his mother died in 1754, the 18-year-old Watt was sent to Glasgow to train as a merchant with his uncle John Muirhead. One of his mothers relatives was the chair of the Oriental Languages and Humanities department at Glasgow College, and Watt became a member of the literary society there. He also met other scholars at Glasgow who would prove influential and supportive of his career: Robert Dick, professor of natural philosophy, Robert Simpson in mathematics, and William Cullen in medicine and chemistry. It was Dick who suggested that Watt go to London to get training as a mathematics instrument maker. With a letter of introduction, Watt left for London in 1755 and began working with the instrument maker John Morgan. Watt was not officially an apprentice, but he did work on mechanical instrumentation: Morgan thought he was talented but took too long to complete his work. The job with Morgan ended in June 1756 and Dick got him a short-term position to work on an astronomical clock, reflecting telescopes, and transit instruments. Watt returned to Greenock at the end of the year, but he soon went back to Glasgow where he began a small business in quadrant-making. He was appointed mathematical instrument-maker at Glasgow College, supported by Dicks replacement John Anderson, and by Cullens replacement and chemist Joseph Black (1728–1799). Black is best known for his work on latent and specific heats and for his discovery of carbon dioxide, and he was to become a staunch supporter of Watt. Early Experimentation In 1759, John Robison, a student at Glasgow, showed Watt a model of the Newcomen steam engine and suggested it might be used to propel carriages. The Newcomen was invented and patented in 1703 by Thomas Newcomen (1664–1729), and Watt began building miniature models using tin steam cylinders and pistons attached to driving wheels by a system of gears. In his own experiments he used, at first, apothecaries trials and hollow canes for steam reservoirs and pipes, and later a Papins digester and a common syringe. The latter combination made a noncondensing engine, in which he used steam at a pressure of 15 pounds per square inch. The valve was worked by hand, and James Watt saw that an automatic valve gear was needed to make a working machine. This experiment, however, led to no practical result and for the next several years, he abandoned this research. Watt stayed with the college until the 1760s, when he took up a partnership with a merchant named John Craig, financed partly with Black. One venture of theirs was producing alkali from salt- in the 18th century, alkali could only be produced from plants. Craig and Watt were one of several people looking for a way to create it chemically, an effort not achieved until 1820. Watt and Craig also worked on pottery kilns and glazes for making tin-glazed delftware. Marriage and Family In 1764, Watt married Margaret Millar, known as Peggy, a cousin he had known since they were children. They were to have five children, only two of which lived to adulthood: Margaret, born in 1767, and James III, born in 1769, who as an adult would become his fathers main support and business partner. The Newcomen Steam Engine Over the winter of 1763–1764, John Anderson at Glasgow asked Watt to repair a model of the Newcomen engine. He was able to get it running, but he was curious as to why the machine consumed so much steam and condensing water. Watts began studying the history of the steam engine and conducted experimental research into the properties of steam. The Newcomen steam engine model had a boiler that was made to scale and was incapable of furnishing enough steam to power an engine. It was about nine inches in diameter; the steam cylinder was two inches in  diameter and had a  six-inch  piston stroke. Watt made a new boiler that could measure the quantity of water evaporated and the steam condensed at every stroke of the engine. Watt soon discovered that the engine required a very small quantity of steam to heat a very large quantity of water. He immediately started to determine with precision the relative weights of steam and water in the steam cylinder when condensation took place at the down stroke of the engine. James Watt independently proved the existence of latent heat, which had been discovered by his mentor and supporter Joseph Black. Watt went to Black with his research, who shared his knowledge with Watt. Watt found that, at the boiling point, his condensing steam was capable of heating six times its weight of water used for producing condensation. Watts Separate Condenser Realizing that steam weight for weight was a vastly greater absorbent and reservoir of heat than water, Watt saw the importance of taking greater care to economize it than had previously been attempted. At first, he economized in the boiler and made boilers with wooden shells in order to prevent losses by conduction and radiation. He also used a larger number of flues than Newcomen had to secure  more complete  absorption of the heat from the furnace gases. He also covered his steam pipes with  non-conducting  materials and took every precaution to secure the complete utilization of the heat of combustion. He soon discovered that the sources of heat loss in the Newcomen engine ­ were: The dissipation of heat by the cylinder itself, which was of brass and was both a good conductor and a good radiator.The loss of heat consequent upon the necessity of cooling down the cylinder at every stroke in producing the vacuum.The loss of power due to the pressure of vapor beneath the piston, which was a consequence of the imperfect method of condensation. His first attempt at a cylinder of  non-conducting  material was made of  ­wood soaked in oil and then baked, which did increase the economy of steam. He then conducted a series of very accurate experiments upon the temperature and pressure of steam by measuring the amount of steam used at each stroke of the engine. He was able to confirm his previous conclusion that three-fourths of the heat supplied to the engine was wasted. Further Improvements After his scientific investigations, James Watt worked on improving the steam engine with an intelligent understanding of its existing defects and a knowledge of their cause. Watt soon saw that in order to reduce the losses in the working of the steam in the steam cylinder, it would be necessary to find a way to constantly keep the cylinder as hot as the steam that entered it. According to James Watt: The idea came into my mind that, as steam was an elastic body, it would rush into a vacuum, and, if a communication were made between the cylinder and an exhausted vessel, it would rush into it, and might be there condensed without cooling the cylinder. I then saw that I must get rid of the condensed steam and injection water if I used a jet, as in Newcomens engine. Two ways of doing this occurred to me: First, the water might be run off by a descending pipe, if an off jet could be got at the depth of 35 or 36 feet, and any air might be extracted by a small pump. The second was, to make the pump large enough to extract both water and air. He continued, When analyzed, the invention would not appear so great as it seemed to be. In the state in which I found the steam engine, it was no great effort of mind to observe that the quantity of fuel necessary to make it work would forever prevent its extensive utility. The next step in my progress was equally easy- to inquire what was the cause of the great consumption of fuel. This, too, was readily suggested, viz., the waste of fuel which was necessary to bring the whole cylinder, piston, and adjacent parts from the coldness of water to the heat of steam, no fewer than from 15 to 20 times in a minute. James Watt had invented his all-important separate condenser. He proceeded to make an experimental test of his new invention. His little model worked very well, and the perfection of the vacuum was such that the machine lifted an 18-pound weight suspended from the piston rod. He then constructed a larger model, and the result of its test confirmed the results of his first experiments. Watt Builds His Own Steam Engine It took years for Watt to figure out the details of the new steam engine. To start with, Watt had to find a way to prevent the condenser from filling with water. He tried several approaches, including an air pump, which relieved the condenser of the water and air which collected in the  condenser and lessened the vacuum. He next substituted oil and tallow for the water used to lubricate the piston, keeping the steam tight and preventing the cooling of the cylinder. Another cause of refrigeration of the cylinder and consequent waste of power in its  operation was the entrance of air, which followed the piston down the cylinder at each stroke, cooling its interior by its contact. The inventor prevented this from happening by covering the top of the cylinder and surrounding the whole cylinder with an external casing, or steam jacket, that allowed the steam from the boiler to pass around the steam cylinder and press on the upper surface of the piston. After building his larger experimental engine, Watt rented a room in an old deserted cottage. There, he worked with mechanic Folm Gardiner. Watt had just met John Roebuck, a wealthy physician, who had, with other Scotch capitalists, recently founded the celebrated Carron Iron Works. Roebuck began to support Watts efforts financially and Watt frequently wrote to Roebuck  describing  his progress. In  August 1765, he tried the small  engine and wrote Roebuck that he had good success, although the machine was very imperfect, and informed Roebuck that he was starting to make the larger model. In  October 1765, he finished the large steam engine. The engine, while ready for trial, was still far from perfect. It nevertheless did good work for such a crude machine. Financial and Personal Setbacks Unfortunately, by 1765, James Watt was reduced to poverty, and, after borrowing considerable sums from friends, he finally had to seek employment in order to provide for his family. During a span of about two  years, he supported himself as a civil engineer, surveying and managing the building of several canals in Scotland and exploring coal fields in the neighborhood of Glasgow for the magistrates of the city. He did not, however, entirely give up his invention. In 1767, Roebuck assumed Watts liabilities to the amount of  1,000 British pounds and agreed to provide more capital in exchange for  two-thirds  of Watts patent. Another engine was built with a steam cylinder seven or eight inches in diameter, which was finished in 1768. This worked sufficiently well to induce the partners to ask for a patent, and the specifications and drawings were completed and presented in 1769. Watt also built and set up several Newcomen engines, partly, perhaps, to make himself more thoroughly familiar with the practical details of engine building. Meantime, he prepared plans for and built a moderately large engine of his own new type. Its steam cylinder was 18 inches in diameter, and the stroke of the piston  was 5 feet. This engine was built at  Kinneil and was finished in  September 1769. It was not all satisfactory in either its construction or its operation. The condenser was a surface condenser composed of pipes somewhat like those used in his first little  model and did not prove to be satisfactorily tight. The steam piston leaked seriously, and repeated trials only served to make its imperfections more evident. He was assisted with financial and moral support by both Joseph Black and John  Roebuck, but  he felt strongly about the risks he ran of involving his friends in serious losses and became very despondent. Writing to Black, Watt said: Of all things in life, there is nothing more foolish than inventing; and probably the majority of inventors have been led to the same opinion by their own experiences. Partnership With Matthew Boulton In 1768, James Watt traveled to London to get his patent submitted, and on the way he met Matthew Boulton. Boulton was the owner of a Birmingham manufacturing company known as the Soho Manufactory, which made small metal goods. He  had inherited his fathers business and built it up considerably. He and his business were very well known in the mid-18th century English enlightenment movement. Boulton was a good scholar,  with a considerable knowledge of languages and science- particularly mathematics- despite having left school as a boy to go to work in his fathers shop. In the  shop, he soon introduced a number of valuable improvements and he was always on the lookout for other ideas that might be introduced into his business. He was also a member of the famous Lunar Society of Birmingham, a group of men who met to discuss natural philosophy, engineering, and industrial development together: other members included the discoverer of oxygen Joseph Priestley, Erasmus Darwin (grandfather of Charles Darwin), and the experimental potter Josiah Wedgewood. Watt joined the group after he became Boultons partner. A flamboyant and energetic scholar, Boulton made the acquaintance of Benjamin Franklin in 1758, who then visited Soho. By 1766, these distinguished men were corresponding, discussing among other things the applicability of steam power to various useful purposes. They designed a new steam engine and Boulton built a model, which was sent to Franklin and exhibited by him in London. They had yet to become aware of the existence of James Watt. When Boulton met Watt in 1768, he liked his engine and decided to buy an interest in the patent. With Roebucks consent, Watt offered Boulton a  one-third  interest. Although there were several complications, eventually Roebuck proposed to transfer to Matthew Boulton  one-half  of his proprietorship in Watts inventions for the sum of 1,000 pounds. This proposal was accepted in  November 1769. Working Steam Engines In  November 1774, Watt finally announced to his old partner Roebuck that he had made a successful trial of the Kilmeil engine. He did not write with his usual enthusiasm and extravagance; instead, he simply wrote: The fire engine I have invented is now going, and answers much better than any other that has yet been made, and I expect that the invention will be very beneficial to me. One reason for his lack of enthusiasm was that his wife had died during childbirth the previous year, in September 1773. Heartsick, Watt buried himself in work. From mid-February 1774 he was working on thermometers and barometers. He ended his civil engineering business in Scotland (in part because of a financial crisis in Scotland) and in May he journeyed south to Birmingham, where he joined the Lunar Society. In 1775, he went into a full-time partnership with Matthew Boulton. From that point forward, the firm of Boulton and Watt was able to produce a range of working engines with real-world applications. New innovations and patents were taken out for machines that could be used for grinding, weaving, and milling. Steam engines were put into use for transportation on both land and water. Nearly every successful and important invention that marked the history of steam power for many years originated in the Boulton and Watt workshops. Retirement and Death Watts work with Boulton transformed him into a figure of international stature among men of letters. His 25-year-long patent brought him wealth; and he and Boulton became leaders in the technological Enlightenment in England, with a solid reputation for innovative engineering. Watt married Ann Macgregor in 1776 and they had two children (Gregory and Jessy), both of whom would die young. James Watt Jr., his son from his first wife, survived his father and went on to have a role in the continuing English Enlightenment. As a result of his partnership with Matthew Boulton, James Watt became a very wealthy man, building an elegant mansion known as Heathfield House in Handsworth,  Staffordshire. He retired in 1800 and spent the rest of his life in leisure and traveling to visit friends and family. He died on August 25, 1819, at Heathfield. He was buried in the graveyard of  St Marys Church in Handsworth. Legacy In a very meaningful way, Watts inventions spurred on the Industrial Revolution and innovations of the modern age, ranging from automobiles and trains to factories and the social issues that evolved as a result. In addition, Watts name has been attached to streets, museums, and schools. His story has inspired books, movies, and works of art, including statues in Piccadilly Gardens and St. Pauls Cathedral. On the statue at St. Pauls are engraved the words: James Watt...enlarged the resources of his country, increased the power of man, and rose to an eminent place among the most illustrious followers of science and the real benefactors of the world.

Review of Financial Statements - Essay Example In this case, also all type of liabilities accounts i.e. current and non current liabilities accounts will be affected. For example, accounts purchases, sundry current liabilities, interest payable, bank loans, long term debt etc 2) The financial statements which will show the impact of the transaction at the time of merge will be balance sheet and cash flow statements. Since in merger a firm acquires another firm therefore balance sheet will record the changes in the assets as well as the liabilities of the firm and the resulting changes in them. Another financial statement which will be affected by this is cash flow statement which will record the movement of any cash paid to the owners/shareholders as the consideration for the merger. (Warren, Reeve, & Duchac, 2008) It is also important to note that the income statement may also be affected if acquiring firm has to expense out some earlier losses of the acquiring firm through provisioning. However, this may not be
