Henry Ford Was Born On July 30, 1863 And Died On April 7, 1947. Henry

Henry Ford was born on July 30, 1863 and died on April 7, 1947. Henry Ford was the son of William Ford, who had emigrated from Ireland in 1847 and settled on a farm in Dearborn, Michigan. Henry disliked farm life and had a natural aptitude for machinery. When he was 15 he went to Detroit and trained as a machinist. Henry Ford began to experiment with a horseless carriage in 1890 and completed his first car, the quadricycle, in about 1896. During the following years he tried unsuccessfully to get it into production. In 1903 he launched the Ford Motor Company with a capital of $100,000 of which $28,000 was in cash. By the time he had formulated his ideal of production: " The way to make automobiles is to make one automobile like another automobile, to make them all alike. He achieved spectacular success with the Model T Ford, introduced in 1809 and eventually produced in 1903 on the moving assembly line. Henry Ford was a major figure in the world's automobile industry for the next 15 years. His production methods were intensively studied and he also startled the world instituting (1914) the then high wage scale of $5 a day. Ford thus became a figure of legend, the native genius that could work miracles. He had considerable mechanical ability but his conclusions were reached intuitively rather than logically. He ran as a Democratic candidate for the U.S. Senate in 1918 and was narrowly defeated. In 1936 he and his son Edsel established the Ford Foundation, to which they bequeathed much of the company's stock. Henry Ford became a victim of his own success in that he clung to the Model T too long, refusing to recognize that its popularity was fading, and consequently lost first place in the automobile industry to General Motors in 1926. He had turned the presidency of the Ford Motor Company over to Edsel in 1919 but never gave Edsel effective authority. Edsel struggled vainly against this situation, and the frustrations of his position undoubtedly contributed to his death at the age of 50. Edsel's oldest son was released from the navy and made an executive vice-president. Unlike his father, who had not been allowed to go to college, Henry II attended Yale University. Henry Ford II recruited talent from outside the company and effected a sweeping reorganization. The company secured firm control of second place in the American automobile industry. In the 1960s it expanded into electronics and astronautics by purchasing the Philco Corporation, and Henry Ford II was regarded as an industrial statesman. He retired from his top company posts in 1979 and 1980.

The means of Civil Rights groups of receiving equality. essays

The means of Civil Rights groups of receiving equality. essays The strive for equality is the main goal for non-violent and militant civil rights organizations but through different means of receiving so. The main non-violent desegregation non-violent groups were CORE, SNCC, SCLC, and NAACP. The top militant civil rights groups were the Black Panthers and the Nation of Islam, also known as the Black Muslims. Both non-violent and militant civil rights groups wanted to be considered equal and receive the same rights as everyone else. Racism reigned supreme in the south when several civil rights groups began to defend their believed rights. Several racist groups took attacks against these civil rights organizers and injured and even killed many members. Both non-violent and militant groups knew that the had to rise above and overcome these racist groups as soon as possible. Though all striving for equality, these civil rights organizations had different intentions in doing so. Organizations such as CORE and SNCC went for the desegregation of schools and public facilities. They would do so in a non-violent manner and belief. Through being calm and non-violent the goal was to provoke anger, rage, and violence from their enemies. As a resul of violent actions shown against calm, peaceful nonviolent protesters throughout the media this would cause many people to become appalled at the actions. The public would not be able to ignore the violence against these innocent people. Some of this violence came about by sit-ins. This was used at several lunch counters. The members would sit at the counters and just wait to be served. Many would be refused service and even be harassed and/or hurt for peacefully sitting at a counter. Other methods used were marches and freedom rides. Members would ride buses through southern towns hoping to be jailed and cause more violence. These tactics took time though. Time and much patience were required to achieve results. The militant civil rights organizations...

Strategic Managment of Galactic Furniture Company Term Paper

Strategic Managment of Galactic Furniture Company - Term Paper Example It emphasizes co-ordination or congruence among the various HRM practices like HR planning, recruitment, selection, training, development, compensation, retention, evaluation and promotion of personnel within the organization to achieve strategic goals (Schuler & Jackson, 1987; Chew and Chang, 1999). Strategic HRM is viewed as 'strategic' as it involves the managerial personnel of the organization and regards. People are the single most important asset of the organization (Poole & Jenkins, 1990). It is proactive in its approach to people. It emphasizes on teamwork, flexibility, employee involvement and organizational commitment (Beaumont, 1993). Many organizations do not assess the short term or long-term implications of their HR policies and practices, which Ulrich (1997 a) emphasizes according to him, " In the 21st century, HR roles are that of the strategic partner, administrative expert, employee champion, and change agent". One of the major responsibilities of HR is to prepare i tself for change and to prepare for as many of these challenges as possible in order to exploit them for competitive advantage. The HR policies and practices should be flexible in nature in order to adapt to these situations. Further, the key to sustained competitive advantage is building and sustaining core competencies within the organization and maintaining flexibility in order to react quickly to the changing global market place. In turn, the incredible advances in technology and the primary role of HRM should be able to felicitate this process.   Management of Change & flexibility:- Schuler (1992) argues that HR activities can be the unifying force in helping an organization to master strategic change. Price (1997) started that effective change requires sure-footed, considerate people manager who can take employees through the process with minimum anxiety and maximum enthusiasm. It requires the recognition that the people of the organization should not be Pawns of strategy but active participants in change.  

Week16 discussion Assignment Example | Topics and Well Written Essays - 500 words

Week16 discussion - Assignment Example The administration of Bush was oriented again in order to give an opportunity for the neoconservatives to make them more powerful over the foreign policy. Bush’s policy doctrines led to long-term interventions in Iraq in 2003 and correspondingly Afghanistan in the year 2001, and are still ongoing. Bush promised cmpassionate conservatism as far as the domestic front was concerned. He also vowed to improve and enhance education, as well as increase financial aid to undeveloped continents such as African (Faragher et al.,28-267) A number of diplomats view the doctrine of President Bust entitled â€Å" preventuve war† was employed during the invasion of Iraq in 2003 (Kashmir, pp124-178). However, the doctrine has a rooted intellectual history of conservative movement regarding the foreign policy. The 9/11 event did not change the traditional desires concerning the offensive foreign policy. Moreover, the development improved the judiciousness of distress, and a narrow window designated for action, that was the epitome of conservative rollback’s advocacy of the course of the cold war period. For instance, Burnham pointed out how hard it was to see the definition of trying and containing. Nevertheless, Bush opposed the possibility of containment due to mass destruction weapons from the unbalanced dictators’ hands (Faragher et al. pp125-289). President Bush said that the danger they were facing from Iraq was significant while authorizing the Iraqi war in October 2002. Consequently, President Bush spelled out that there was no need to wait for the threat to materialize since the danger Iraqi was facing was gradually becoming worse. Within the year 2002, Bush added that the terror war relied on the self-protective technique (Hamm, pp245-289). The 9/11 event never changes the thinking of conservative foreign policy; instead, it alters the political environment that it functioned. With the departure of President Bush from the White House or the debacle of Iraq,

The hedge fund and private equity capital raising environment in EU Essay

The hedge fund and private equity capital raising environment in EU - Essay Example Most hedge funds establish and organize themselves as limited partnerships because of the flexibility that it allows them. In order to withdraw funds investors have to give notice of 30 days or more. There are approximately 7,000 hedge funds with market values of US$1 trillion. According to McCaherty and Vermeulen (n.d.) hedge funds take a variety of forms and are characteristic of the pursuit of high returns and the use of leverage to enhance the return on their investment. In recent times hedge funds and private equity have come to represent a significant part of financial activities in the financial markets in Europe, USA and Asia. The sizes of these investments are large as they continue to grow. Fund managers use a number of strategies, traditional techniques and a number of instruments such as equity, debt, options, futures and foreign currencies. In recent times hedge fund managers have engaged in high risk investment strategies including currency trading, credit derivatives a nd restructurings in order to obtain above normal returns on their investments Private Equity Private equity fund managers invest mainly in unregistered securities. However, in recent times they have been engaged in taking private a number of publicly listed companies. They use a number of different investment strategies with varying levels of liquidity. Private Equity Firms are not only involved in providing funds for new and developing companies but they are also engaged in the provision of funds for corporate restructuring, management buy-out and leveraged buy-outs. One Writer attributes the emergence of the buyout fund as the dominant style of investment to favorable credit market conditions, a large supply of loan funds and low interest rates, changes in the preferences of investors, a large number of publicly listed private equity vehicles and the increase in the demand for alternative assets by institutional investors such as pension funds. Brigham and Ehrhardt (2005, p. 664) indicates that â€Å"in a going private transaction the entire equity of a publicly held firm is purchased by a small group of investors that usually includes the firms current senior management.† There are usually two ways in which this transaction is carried out. In one instance the managers acquire all the equity of the company and in the other it does so with a small group of investors who set the previous managers to manage. These are referred to as management buy-out (MBO) and management buy-in (MBI) respectively. This process normally involves substantial borrowings and is therefore described as Leveraged buyouts (LBO). Another term which is normally used is â€Å"taken private† which relates to a buyout of a public company and in the process removing it from the stock exchange listing, and therefore transforming it into a private firm (Fraser-Sampson, 2007). Public companies are normally taken private because they have the potential of providing substantial ca sh flows to investors as the shares are currently undervalued on the stock market. The managers see the potential of â€Å"significantly boosting the firm’s value under private ownership† (Brigham and Ehrhardt 2005, p. 664). This means that companies taken private have the potential of enriching not only the managers who take part in the buyout but the public shareholders who are often offered prices higher than the going market

The genesis of elements

The genesis of elements Introduction The periodic table is continually enriched with new elements synthesised by nuclear reactions in laboratories, but only 90 of all the elements occur naturally. Those are found between atomic numbers 1 to 92, which is from 1H to 92U, excluding the elements technetium (43Tc) and promethium (61Pm). The latter two are made artificially, even though technetium has been recently discovered in stars. All the elements are made from two fundamental building blocks, the protons and the neutrons, given the term nucleons. These are packed together into nuclei, with each element containing a different ratio of protons and neutrons in its nucleus. The nucleons can only be produced or annihilated at very high energies, and this occurred at the beginning of the universe. What happened the first moments of the creation of the universe and how were the elements synthesised? are the questions around which this report is circulated. Using astrophysics to discuss the universe creation is beyond the purpose of this report, and therefore most of the physical equations are excluded. All the terms are explained in simple scientific terms. The areas discussed are how the universe began and how the elements were formed in this universe creation timeline, including any relevant nuclear reaction equations and theories that lead to the creation of the chemical elements as we know them at present. [1, 2] The Big Bang and the origin of the chemical elements The most widely accepted theory in cosmology is currently the Big Bang Theory, which was based on Einsteins General Theory of Relativity (E=mc2). According to this, the universe was once concentrated in a small primeval nucleus of extremely high temperature and infinite density. For some reason, that hot, dense state began to expand homogeneously and cool down at an incredibly fast rate. This sudden expansion into space, distributing radiation and matter everywhere uniformly, gave rise to the birth of the universe and it is known with the misleading title Big Bang (even though it was not an explosion but an expansion). The reason that caused this sudden expansion is not known yet, and scientists are still trying to give an answer to this big cosmology question with many research projects taking place in this field for the past few decades. It is beyond modern science to define what happened before the Big Bang since time and space came into being at that moment. According to this theory the universe is about 15 billion years old. But which are the evidence that this Big Bang actually occurred? [1, 5, 6, 7, 8, 9] Universes expansion In 1929, Edwin Hubble discovered that the universe is expanding and that the galaxies that make up the universe are moving away from our galaxy with velocities proportional to their distance from us. Hubbles law describes this expansion, stating that the farther a galaxy is from us, the greater its radial velocity of recession. Hubbles equations as follows [9]: v (radial velocity) = H (Hubble constant) x d (distance) In simple terms this means that the most distant galaxy is moving away from us at the fastest rate and the nearest at the slowest. This, however, does not mean we are at the centre of the universe, since every observer in the universe sees all objects moving away from them with velocity proportional to the distance. So although the universe is expanding, it looks the same from every single galaxy. Hubbles conclusions resulted from observing the velocities via the redshift, which is the Doppler Effect applied to light waves. Each galaxy has a set of emissions and absorptions seen in their spectra and their characteristic frequencies are known. The characteristic lines from galaxies spectra turn out to move towards the red end of the spectrum, which means the galaxies are receding from us. This effect is known as the redshift. If the galaxies were moving towards us the light waves would be crowded and the frequency would be raised. Since the blue light is of high frequency, a shift towards the blue side of the spectrum would be obtained, giving a blueshift. But this does not occur, and the galaxies are all redshifted. The proportional relationship between speed and distance indicates that in the past all the matter must have been concentrated at a point of extraordinary high density, from which it expanded to its present form. Hubbles discovery provides one of the evidence for the Big Bang Theory. [6, 9, 11] Cosmic Background Radiation In 1965, Penzias and Wilson were investigating the radio noise found at wavelengths between a few millimetres and a few centimetres, by means of a special low-noise radioantenna. Once all the known sources of noise were identified, a remaining signal of radiation was left as an annoying excess noise. This signal was coming from all directions and the noise did not change in intensity with the direction of the antenna in the sky or the time of day and season. This radiation was identified to be Cosmic Background Radiation. The radiation that Penzias and Wilson discovered was seen as the dying remnants of the Big Bang, and was probably formed due to photon production from matter-antimatter annihilation. Once the photon background was produced, it cooled with the expansion of the universe leaving behind this background radiation. This radiation contains more energy than the rest of the universe (stars and galaxies). In the universes early life, when it was very hot, radiation could not travel very far without being absorbed and emitted by some particles. This constant exchange of energy maintained a state of thermal equilibrium and therefore a thermal spectrum can now be obtained. In 1989, Cosmic Background Explorer (COBE) satellite was launched which took measurements from above the earths atmosphere, obtaining more accurate results for this radiation than Penzias and Wilson. The shape of the spectrum of thermal radiation that was observed at the temperature of 2.73K was very similar to that of a blackbodys spectrum at the same temperature. The cosmic microwave spectrum shows that this radiation was generated in equilibrium conditions since it has a thermal shape. The radiation is also known as the 3K radiation or the Cosmic (comes from all directions) Blackbody (because of its spectral shape) Microwave (since its spectrum peaks at cm to mm wavelengths) Radiation CBM. In 2001 the Wilkinson Microwave Anisotropy Probe (WMAP) was launched by NASA, designed to determine the geometry, content and evolution of the universe and to make fundamental measurements of cosmology. WMAP successfully produced a full-sky map of the temperature anisotropy of the cosmic microwave background radiation, and it still continues to collect data from space. The results from the different measurements of the cosmic background radiation taken through years are shown in the figure following. Furthermore, the measured uniformity of the radiation confirmed some assumptions about some of the universes properties: its homogeneity (it looks the same at each point) and its isotropy (it looks the same in all directions). To summarise, two evidences supporting the Big Bang Theory have already been discussed: The Big Bang Theory explains Hubbles observation that the universe is expanding, since it must have started its expansion from a hot and dense state in its early life. It accounts for the existence of the cosmic background radiation observed by Penzias and Wilson, and confirms the assumptions that the universe is homogeneous and isotropic. The third evidence for the theory is that it accounts for the origin and the abundances of the light elements that exist in the universe. [6, 7, 9, 12, 14] The timeline of the Big Bang Before the Big Bang the universe was compressed into a hot and dense nucleus. When the Big Bang occurred, the universe began to decompress rapidly. The modern science has not yet defined what happened earlier than Plancks time which is at 10-43s after the Big Bang. At that time the four forces of nature were unified in a single super force (also referred to as Wald), being equally powerful. The four forces are divided in the next two categories: Forces between particles (operate over large distance): Electromagnetic Gravity Forces in subatomic domain (operate over very short distances): Strong nuclear force (it holds the nuclei of atoms together) Weak nuclear force (it crops up in radioactive decay and helps fission) The forces strength is as follows: Strong > Electromagnetic > Weak > Gravity In the primeval fireball formed after the Big Bang, the photons energy was so high that they can collide to form particles (creation of matter from light and formation of matter and antimatter in pairs. This is seen from the Einsteins equation, E=mc2, which doesnt say that this relationship is irreversible. So matter can become energy or energy can become matter! [5, 9, 10] Some important terms, which are mentioned on the above timeline, are very briefly explained below [9, 10]: Quarks are the elementary particles that make up the protons, neutrons etc. A proton is made out of three quarks: 2 up and 1 down quark. Neutron is made out of 2 downs and 1 up. The antimatter has the same properties as the regular matter except that it has the opposite electrical charge. Inflation is the early phase of the exponential growth of the universe. Baryons are particles made out of 3 quarks. Out of those particles only protons and neutrons are stable; therefore the baryonic matter in the universe is considered to be made mostly out of them. The electrons are often included in the term baryons even though they are not made out of three quarks. The universe has neutral charge, i.e. 1 electron for every proton. Radiation: what we see in the universe comes from electromagnetic radiation. The light is made up from individual particles, the photons, ?. These protons spread at the speed of light, and (mostly the high energy ones) can interact with baryons and electrons; for example they ionise an atom by taking off an electron. Neutrinos are extremely weak interacting, massless particles produced in radioactive decay The particles that were present in this cosmic nucleosynthesis are given in the following table: In general, the universe is made out of the following [10]: Baryons (p, n, e) Radiation (photons) Neutrinos Dark Matter and Energy Nuclear Processes taking place during the element formation The light elements of the periodic table were produced during the beginning of the life of universe, whereas the heavier elements were produced later by thermonuclear reactions that power the stars. The early universe could be viewed as a type of thermonuclear reactor. However, the abundances of the light elements produced soon after the Big Bang, have changed at present due to the nuclear processes in stars and other subsequent events in the interstellar medium. Some of the reactions taking place during the life of the universe until now are shown on the following table. Element Abundances The abundance of the elements is the third evidence supporting the Hot Big Bang theory as seen earlier. These abundances are obtained from detailed spectroscopic analysis of samples taken from earth, meteorites, comets, moon, planets etc. The chemical element abundances can be recorded in three different ways [16]: Mass fraction: the mass of a constituent of a mixture over the total mass of all the constituents in the mixture à   w = a / (a+b+c+) Volume fraction: the volume of a constituent of a mixture over the sum of the volumes of all constituents before mixing. For gases, the volume fraction is similar to the mole fraction à   ? Mole fraction: the number of moles of a constituent over the total amount of all constituents in the mixture à   x The graph has some certain features and trends which are seen below [1, 2]: There is an approximately exponential decrease from H until A~100 (atomic mass number) or Z~42 (atomic number). Then, gradual decrease is observed. For higher A, the rarity of synthesis increases showing that the stellar evolution (which builds the heavier elements) is not very common. A peak is seen between Z=23-28, i.e. for elements V, Cr, Mn, Fe, Co, Ni. At the maximum of the peak lies iron, and it is seen that Fe is 103 times more abundant than expected compared to its neighbouring elements. The e-process (equilibrium). Iron lies on the maximum energy that can be released in stellar nucleosynthesis with the element burning processes. After this, the elements form mostly by neutron capture. The elements D, Li, Be, B are rare compared to their neighbouring H, He, C, N which are highly abundant. Their production is insufficient. Also they are consumed at very high temperatures in the stellar interiors. These elements are mostly made by stellar spallation. Light nuclei up to Z~21 having their A divisible by 4 are more abundant than their neighbours. This was observed by G. Oddo in 1914. These elements are alpha particle nuclei (e.g. O16, Ne20Ca40, Ti48). It is seen that the He-burning and alpha-process are more efficient than the H-burning and s-process in these regions. Double peaks can be seen at A = 80, 130, 196 (peaks due to neutron capture with r process) with A = 90, 138, 208 (due to neutron capture with the s process) Magic numbers at N = 50, 82, 126 for progenitors and stable nuclei Atoms with even atomic mass number, A, are more abundant that those with odd A, therefore the alternate peaks (up and down) are seen in the graph. Heavy atoms tend to be neutron rich. Proton rich heavy nuclei are rare This is because the proton- rich nuclei are produced in the p- process which is rare compared to the r- and s- processes. The r and s peaks seen in the following smoothed curve correspond to the elements formed by the slow and rapid neutron capture processes. Some elements require the neutron capture to be slow enough so that intervening beta decays can occur. However, some other elements need neutron capture to happen very fast to be able to form through some short-lived nuclei. [18] Big Bang Nucleosynthesis The Big Bang Nucleosynthesis (BBN) occurred a few brief moments after the beginning of the universe, way before the stars existed. The light element formation happened via nuclear fusion reactions (a process by which smaller nuclei are joined into larger ones), which raged throughout the universe. It is also known as Cosmic or Primordial Nucleosynthesis. For nuclear reactions to occur, some conditions should be present, which were both satisfied in the early universe: The temperature and density should be high enough, so that the kinetic energy of nucleons can overcome the coulomb barrier The particles must come close enough for the attractive nature of the strong nuclear force to overcome the repulsion of the electromagnetic force between the positive charges of the particles (protons). As seen earlier, the universe was born by expansion from a hot, dense state in which its constituents were elementary particles. Atomic nuclei, except from the proton, began to form through nuclear fusion reactions, which could not take place until the temperature was low enough for them to occur. When the universe was about 1 second old, protons became available for fusion, and a proton and neutron can be combined to form a deuteron. However, the deuteron was destroyed by photodissociation (break up of a nucleus by high energy gamma rays) before the more stable helium was formed. At this stage fusion could not proceed further until the universe was cooled further. At about 100s after the Big Bang, the temperature had fallen to 109K and fewer deuterons were destroyed, allowing 4He to form, along with all the isotopes of hydrogen and helium below 4. No considerable amounts of elements above nucleus 4 were formed since there are no stable nuclei of atomic number 5 and 8. However, traces of 7Li and 7Be were formed. At 1000s, the temperature had fallen too low for particles to have enough energy to overcome the coulomb barrier. Therefore, the fusion reactions stopped occurring and the abundances of the elements were frozen. Most matter existed as rarefied gas for a few hundred million years until it was slowly drawn towards a star, where more reactions could take place, due to higher temperatures. The only nucleus formed in a considerable amount was 4He, with some traces of lighter nuclei. Most of the material continued to be 1H. Light element formation Deuteron formation through fusion of a proton with a neutron gives out a photon of high energy (gamma ray). Most of the energy is carried away with this gamma ray, allowing the proton and neutron to bind. Otherwise, they would bounce off each other. The reversible reaction is also true, so a gamma ray can destroy the deuteron. n + p à   d + ÃŽ ³ When there is not anymore sufficient energy and collisions to form many deuterons, they start combining to form helium nuclei: d + d à   4He + ÃŽ ³ However, some two step processes can occur between the proton, neutrons and deuterons to form the helium and hydrogen isotopes, 3He and 3H, as a between step. These two step processes are: p + d à   3He + ÃŽ ³ n + 3He à   4He + ÃŽ ³ and n + d à   3H + ÃŽ ³ p + 3H à   4He + ÃŽ ³ These processes can happen in the forward or backward way, until they reach equilibrium. Neutron decay In the early universe, the temperature was high enough for free protons and neutron to exist in thermal equilibrium at high energies. The free neutrons would travel long distances before colliding with other baryons, having a great chance of decaying into protons. n + ve ßà   p + e- + 0.8MeV (ve is e- neutrino)[ref.2] When the thermal energy drops below 0.8MeV it is hard for backward reaction to occur and therefore more neutrons decay into protons, setting the ratio of n:p to 1:5. However, as soon as the energy falls more (about 0.1MeV) the neutrons manage to form nuclei and become stable, with the ratio now being n:p to 1:7 due to further reduction of the number of neutrons by decay that occurred in the time that it took for the energy to fall. As seen, the only elements produced in significant abundance are 1H and 4He. 4He is formed since it is the most stable of the light elements and 1H is present since there are not enough neutrons to react with the protons (1:7 ratio of neutrons to protons) and a large amount of protons are left over. In universes primordial composition 4He is found to be about 25% (mass fraction). Since 4He is four times heavier than 1H, it implies that there is one helium nucleus for every twelve hydrogen ones. Other elements abundances are (compared to 1H abundance): D =10-4, 3He = 10-5, 7Li = 10-10 [ref.2] The mole fraction of the elements is H 88.6% and 4He 11.3%. Since H and He account for 99.9% of the atoms in the universe, it is concluded that nucleosynthesis of heavier elements has not yet gone very far. [ref.4] At present, the observed abundances of the elements are successfully reproduced by the Big Bang Theory (providing an evidence for the theory). However, the present composition of the universe is slightly altered from its primeval composition, because of the nuclear reactions occurring in stars. Stellar Nucleosynthesis Stellar nucleosynthesis is the fusion process that powers the stars, forming heavier elements out of the lighter ones. The main reactions taking place during this process are summarised in the table below, and then discussed more broadly. Hydrogen burning Hydrogen burning is the fusion of four hydrogen atoms to form a helium one. This happens through two different routes: [ref.6] Proton-proton chain. This is the primary energy producing process in most stars, especially in low mass stars like our Sun, and is as follows) p + p à   d + e+ + ve p + d à   3He + ÃŽ ³ 3He + 3He à   4He + p + p The fusion of two protons to form a deuteron (the nucleus of a deuterium atom with 1p 1n) 3He is an isotope of helium with 2 p and 1 n 4He is the most common isotope of helium, having 2p and 2n. In the 1st step takes a very long time to occur (5109 years), since it involves the weak nuclear force and there is a very small cross section. This is the reason for the long life of stars. The 2nd step involves the electromagnetic interaction and occurs in about 1 second, whereas the 3rd step involves the strong nuclear force, taking about 3105 years. CNO cycle. It is another method for burning of hydrogen, using carbon, nitrogen and oxygen as catalysts. These get consumed so as to help the process occur, but are afterwards reformed. p + 12C à   13N + ÃŽ ³ 13N à  13C + e+ + ve p + 13C à   14N + ÃŽ ³ p + 14N à   15O + ÃŽ ³ 15O à   15N + e+ + ve p + 15N à   12C + 4He Nitrogen nucleus decays Oxygen nucleus decays Helium Burning (triple-alpha reaction) Hydrogen burning releases 90% of the total energy available from fusion. The rest is coming half from the helium burning and the other half from other nucleus burnings up to 56Ni or 56Fe. However, since 5Li and 8Be are unstable, fusion after He can continue only at high density. During the triple-alpha process three 4He nuclei fuse to form 12C. Then, helium and carbon react so as to form oxygen. Some reactions are: 4He + 4He ßà   8Be An almost 100% reversible process since 8Be is highly unstable. 4He + 8Be ßà   12C* An excited state of 12C is formed and almost all decays back to He and Be. 12C* à   12C + e+ + e- However, about 0.2% decays into a stable carbon nucleus. When the 8Be barrier has been passed and the triple-alpha process forms carbon, the following also can occur: 4He + 12C à   16O + ÃŽ ³ 4He + 16O à   20Ne + ÃŽ ³ Carbon Burning The carbon burning follows when the star has run out of helium fuel. This can give three different products. 12C + 12C à   20Ne + 4He 23Mg + n 23Na + p Oxygen burning etc. Oxygen burning: 16O + 16O à   28Si + 4He Neon Burning: 4He + 20Ne à   24Mg + ÃŽ ³ A 28Si can dissociate into 7 4He and react in silicon burning. Silicon Burning: 28Si + 74He à   56Ni (which can then ?-decay to 56Fe during or after a type II supernova) From the above reactions protons, neutrons and alpha particles are released, which are then available for additional captures so as to form further isotopes of the elements. The mass barriers in the element formation In 1939 Bethe observed that no elements heavier than helium can be built up to any appreciable extent, since there are no stable elements of mass 5 nucleus. No reasonable ways of formation of elements could be given, since none of them would work: The addition of a neutron or a proton onto helium can not occur to form a mass 5 nucleus (unstable) The direct formation of 8Be out of two 4He is not possible due to the fact that 8Be is very unstable, with negative binding energy The formation of 12C out of three helium nuclei would not work either. However, at sufficiently high temperature and density 4He can bind to form 8Be and therefore the mass 4 barrier can be passed. This beryllium formed, even though very unstable and at low quantities in the star interiors, it is enough to form 12C when another helium nucleus is added to it (Salpeter, 1952). Once the unstable mass 5 and 8 barriers are overcome, more elements can be formed. Beyond the Iron Peak Explosive Nucleosynthesis The normal nuclear fusion reactions occurring in the star interiors can only form elements up to iron, 56Fe. They do not produce any elements beyond the iron peak since this would require energy rather than yielding energy. Beyond the iron peak, elements can be formed mainly by neutron captures. After 83Bi, no more stable isotopes can be formed. Neutrons are produced by some of the processes seen earlier, and one of the most favoured one is: 13C + 4He à   16O + n In stars, mass loss processes, where a return back to the interstellar medium material occurs which is however altered from when it formed the star, are very common. These can be mild and form planetary nebulas, or can be violent and catastrophic explosions, known as novae and supernovae. During the latter processes, heavy elements are form rapidly before or after the explosion with neutron captures. The two main types of neutron capture synthesising the heavy elements have been briefly discussed earlier (see p.13) and they are the following: S-process (Slow neutron capture) R-process (Rapid neutron capture) An unstable species has to decay before capturing another neutron, and therefore the s-process produces the less neutron rich compounds, since the process is slow enough, it allows beta decay by electron emission and the isotopes are stable before a lot of neutrons have been added. However, during the r-process the neutrons are added rapidly and the nuclei do not have enough time to decay, allowing more neutrons to be added until they can not accept any more. This process forms the more neutron rich elements. Other processes The proton rich isotopes of the heavy elements are formed by the p-process, i.e. proton captures. The elements 2H, 3He, 6Li, 7Li, 9Be, 10B and 11B, as well as some less neutron rich isotopes are not produced in significant amounts form the Big Bang and are less abundant than their neighbours. They are mostly formed during spallation reactions (fragmentation), during which more abundant elements (like C, N and O) are broken up in reactions between cosmic rays and the interstellar gas. The cosmic rays consist of small subatomic particles (mainly p and He nuclei) which travel through our atmosphere from space at the speed of light. They are created in supernovae and some star interactions. The particles in the cosmic rays are accelerated by the galaxys magnetic field and fly towards every direction. During their journey around the galaxy, the heavier particles of the cosmic rays collide with the atoms in the interstellar matter (mostly 1H and 4He), causing fragmentation, producing those lighter elements. Nova Some stars in the galaxy for binary systems, in which there are two stars revolving around each other. If their masses are different the bigger star will evolve faster and at some point their atmospheres combine, causing instabilities to form, resulting to an outburst of energy and matter as an explosion. This increases the luminosity of the stars and a nova is seen. During this procedure, heavy elements are synthesised. Supernova A supernova is a catastrophic stellar explosion during which so much energy is released that all the billions of stars can be outshined by it. It occurs when an evolving star runs out of nuclear fuel, and the core is so unstable that it collapses rapidly (in less than a second!). Just before or during this explosion, thousands of nuclear reactions (neutron captures) occur in a very short time, and form heavy elements. The remains of the supernova spread out into space and can be used in the formation of new stars or can be captured by other evolving stars. Conclusion In this report some of the well known up to date discoveries of cosmology were discussed. However, the universe is so infinite and mysterious that many questions about its creation and the element formation remain unanswered and plenty of areas are still in dark. NASA is currently the largest organisation performing investigation evolving around important cosmological questions, with its program Beyond Einstein. The satellites COBE and WMPA try to find an answer to what powered the Big Bang, whereas other missions wish to discover what the mysterious dark energy causing the expansion of the universe is. Fascinating findings about our universe and the genesis of elements are awaiting to be brought to light in the years to come. References (in order of appearance in text) Greenwood, N.

Software Piracy :: Free Essay Writer

Software Piracy Software Piracy: A Big Crime With Big Consequences Imaging for a moment that you come across an advertisement saying you can meet up with an individual who will break into a store, disarm all of the alarms and will hold the door open for you as you walk inside and take anything you wish. This criminal offence occurs every day on computer systems around the world including the internet. This is a very serious problem and is very difficult to circumvent. Every computer user is both tempted and immersed in software piracy in its many forms. One of the most disturbing facts behind this crime is that many people who participate in the distribution of commercial software don't even know they are committing a crime. Software piracy is a very serious and widespread crime that must be acknowledged and dealt with. Software piracy is the unauthorized duplication and or distribution of copyrighted programs. There are two ways to be involved in software piracy. The first is facilitation. Facilitation is the deliberate copying of copyrighted software and distributing it. An example would be an MIT student named David LaMacchia. This individual served and maintained a computer that was connected to the internet that offered it's users more than one million dollars worth of software 'free of charge.' Mr. LaMacchia was caught by the authorities and was acquitted of this piracy due to the lack of legal standards for this crime. Another example is off local bulletin board systems. Many are run out of the offenders homes with just a phone line, a computer and a modem. Here members of this service can send and receive pirated software (otherwise known as 'warez') as their own pace and leisure. There are not just one or two of these bulletin boards around there are in fact many. Most reside in l arge cities and the offenders are in most cases minors. As the computer gains a more stable hold on our society these bulletin boards are replaced by the ones that are linked to the internet. By this individuals can anonymously put out copyrighted software for the use of any anonymous user of the internet such as the type of system that Mr. LaMacchia ran. The second way to be involved in software piracy is to be on the receiving end.

Corporate Social Responsibility †McDonald’s Essay

McDonald is one of the most renowned fast food restaurants across the globe. The vision of McDonald’s was coined by Ronal McDonald who identified the need of its target audiences and tailor made the products as per them. The organization has established a value proposition for the target audience on the basis of a penetration pricing strategy that has appealed to the people in almost every country. Being a tough competitor to many fast food retailing giants such as the Burger King, KFC etc, the organization has implemented an adaptation approach for every country that it enters. This implies that McDonald is willing to change its product portfolio and other strategies as per the expectations of the customers in the newly entered market. This allows McDonalds to create a link with the target audience 1 McDonald and synchronize with their taste and preferences. For instance, when McDonalds entered the Indian markets in 1996 with its famous beef burger, it never expected that the Indian people will boycott the product because of their cultural norms and tradition. This forced the company to re-evaluate its strategies and introduce a new product â€Å"Aloo tikki† burger (Burger with potato stuffing) which was in line with the Indian sentiments. â€Å"Aloo tikki† has been one of the most preferred snacks for the Indian markets. Although it is not at all a healthy product but still it is in the taste and preferences of the customers. Therefore, the product was customized according to the customers. In the Australian market, the organization has even changed its brand name recently and is opening its outlets by a new nick name ‘Macca’. This is the extent of the adaptation strategy that the world has witnessed. Previously no organization has taken the initiative of changing its brand name to appeal to the target audience but McDonald has undertaken the same only to create a relationship with the target audience. The notion of corporate social responsibility has gained a lot of popularity in the recent past because of the increasing involvement of the organizations in the day to day life of the people. The concept states that an organization also has a lot of responsibilities towards its stakeholders that includes its employees, customers, suppliers, banks, financial institutions, government and the society on a whole. Therefore, the organizations should not undertake any activity that goes against the interest of the society. In fact, every organization should undertake activities that create some kind of welfare for the entire society. For instance, many organizations goes to the backward areas and provide free medical checkup for the people, distributes medicines, provides education to the children, spreads awareness regarding the women empowerment etc. All this constitutes of the corporate social responsibility activities of an organization. This also helps an organization in creating positive brand image in the 2 McDonald minds and hearts of the target audiences because they might feel high of an organization and its activities. However, in the last few years, a lot many social groups and institutions have doubted the ethics of the company and have clearly stated that McDonald does not follow the concept of corporate social responsibility. This is mainly because the organization has been introducing numerous products in the market that are harmful for the health of the customers and increases the obesity level in them. In anticipation of higher profits, many a times, the organization might not follow the ethical code of conduct that might affect their sustainability in the near future. The same has been talked about McDonald’s because its products are just for the profits of the company and has a negative impact on the obesity level of the consumers. It is a very transparent fact that obesity has become a major problem across the globe and the same should be controlled in order to have a healthy life. However, many experts and doctors have identified obesity, blood pressure and diabetes as some of the rising problems amongst the Americans and amongst the people across the globe. Not only obesity gives rise to several serious diseases in a human body but it might also affect the confidence level of an individual. This is the main reason because of which many experts have imposed serious allegations against the corporate social responsibility of McDonald’s. In this reference a lawsuit was also filed on McDonald’s in the year 2003 when an obese man named ‘Ceaser Barber’ filed suit against McDonald’s for the unhealthy products that it sells that has led to high level of obesity. However, the judge denied the law suit and McDonald’s was relieved of the case. However, in another case McDonald was considered as guilty and unethical when Stella Lieback spilled coffee (purchased from McDonalds) on her pelvic area and filed a case against the company for selling such hot coffee. The court of law found the company guilty because the lady had suffered a three sixty degree burn. 3 McDonald Nevertheless, keeping the above discussion into consideration, I must state that the concept of corporate social responsibility does not states that the organizations can not develop a product portfolio as per the needs of the target audiences. McDonald’s has rightly identified the needs of the customers and have developed these products as per their taste and preferences. Since it is the need of the customers, it cannot be ignored by an organization manufacturing the similar product lines. The key concept of marketing states that an organization has to understand the needs of the target audience and develop the products to satisfy the unsatisfied needs (Azad, 2011). The same task is being followed by the organization. The competing brands such as Burger King, KFC, Domino’s, Pizza hut and many others are also manufacturing the fast food items as per the taste of the target audiences. Therefore, McDonald’s also has to remain in the competition for obtaining a sustained growth in the market place. Above all, McDonald’s is not forcing any individual to purchase the product. It is the free will of the target audience to purchase the product from the organization and consume the same. If the consumers have deep respect for the organization’s effort in the past few decades and have a liking towards its product, the same cannot be categorized as unethical or against the concept of corporate social responsibility. As a consumer I have deep knowledge about the product that McDonald’s sell and its impact on the health of the consumers. The law of many countries states about the provision of ‘caveat emptor’ which means let the buyer beware of the products or services that they buy. This implies that the consumers are themselves aware of the products and if they are purchasing it with free will, the organization cannot be held responsible for it. In a nutshell, I feel that corporate social responsibility does not mentions anything in black and white in reference to the product’s quality. It just states in broad that the organization should not go against the interest of the society. McDonald’s, by no means, is going against the society. Rather the organization is undertaking a genuine attempt to serve to the needs and 4 McDonald wants of the target audience (Sharma, 2012). This should be appreciated by the stakeholders to encourage the efforts from McDonald’s in the future. I would like to conclude that there cannot be a universal standard for developing the product. It is highly dependent from situation to situation and should not be blamed on corporate social responsibility of the organization. References Azad, P. (2011). Marketing Management.

The Old Man And The Sea Essays - American Literature, Free Essays

The Old Man And The Sea Essays - American Literature, Free Essays The Old Man And The Sea The Old Man and the Sea is a heroic tale of man's strength pitted against forces he cannot control. It is a story about an old Cuban fisherman and his three-day battle with a giant Marlin. Through the use of three prominent themes; friendship, bravery, and Christianity; the Old Man and the Sea strives to teach important life lessons to the reader while also epitomizing Santiago, the old fisherman, as a Hemingway code hero. The relationship between Santiago and the boy is introduced early in the story. They are unlikely companions; one is old and the other young, yet they share an insuperable amount of respect and loyalty for each other. Santiago does not treat Manolin as a young boy but rather as an equal. Age is not a factor in their relationship. Manolin does not even act as a young boy; he is mature and sensitive to Santiago's feelings. He even offers to disobey his parents and accompany Santiago on his fishing trips. Santiago is viewed as an outcast in his village because he has not caught any fish for more than eighty-four days and is therefore unlucky. Nonetheless Manolin is loyal to Santiago and even when his parents forbid him he wants to help his friend. Their conversations are comfortable, like that of two friends who have known each other for a long time. When they speak it is usually about baseball or fishing, the two things they have most in common. Their favorite team is the Yankees and S antiago never loses faith in them even when the star player, Joe DiMaggio is injured with a heel spur. In this way Santiago not only teaches Manolin about fishing but also about important characteristics such as faith. In the story Santiago's bravery is unsurpassed but it is not until he hooks the great fish that we truly see his valor and perseverance. Through Santiago's actions Hemingway teaches the reader about bravery and tenacity in the face of adversity. He demonstrates that even when all is lost and seems hopeless a faith and willful heart will overcome anything. Santiago had lost his luckiness and therefore the respect of his village. Through the description of his cabin we also suspect that Santiago is a widower. Although Santiago has had many troubles he perseveres. He has faith in Manolin, in the Yankees, in Joe DiMaggio, and most importantly in himself. This is perhaps his greatest attribute because without it he would never have had the strength to persevere and defeat the giant Marlin. Faith is not the only thing that drives his perseverance. Santiago also draws upon his past victories for strength. After he hooks the Marlin he frequently recalls his battle with a native in what he calls the hand game. It is not just an arm wrestling victory for him it is a reminder of his youthful days. His recollections of this event usually proceed a favorite dream of his in which he sees many lions on a peaceful shore. These lions represent him when he is young and strong and could overcome any challenge. Although he is an old man and his body is no longer like it used to be his heart is still great and he eventually defeats the Marlin. Santiago's perseverance and bravery are further illustrated when he tries to fight off the sharks. He was a fisherman all his life and therefore he knows that the fate of his catch is inevitable yet he persists to fight the sharks. The battle between him and the sharks is about principles not a mere fish. Santiago is still a great warrior at hea rt and warriors fight until the end. One of the greatest and most obvious pieces of symbolism in the story is Christianity. From the beginning of the story the reader is shown a unique relationship between Santiago and Manolin. Their relationship parallels that of Christ and his disciples. Manolin is Santiago's disciple and Santiago teaches Manolin about fishing and life. One of the greatest lessons that Santiago gives is that of a simple faith. Have faith in the Yankees my son. This type of faith reflects the basic principles of Christianity. Hemingway's

Origins and Use of Amaranth in Prehistoric America

Origins and Use of Amaranth in Prehistoric America Amaranth is a grain with high nutrition value, comparable to those of maize and rice. Amaranth has been a staple in Mesoamerica for thousands of years, first collected as a wild food, and then domesticated at least as early as 4000 BC. The edible parts are the seeds, which are consumed whole toasted or milled into flour. Other uses of amaranth include dye, forage and ornamental purposes. Amaranth is a plant of the family of Amaranthaceae. About 60 species are native to the Americas, whereas less numerous are the species originally from Europe, Africa, and Asia. The most widespread species are native to North, Central and South America, and these are A. Cruentus, A. caudatus, and A. hypochondriacus. Amaranthus cruentus, and A. hypochondriacus are native of Mexico and Guatemala. The first one is used in Mexico to produce typical sweets called alegrà ­a, in which the amaranth grains are toasted and mixed with honey or chocolate. Amaranthus caudatus is a widely distributed staple food both in South America and in India. This species originated as one of the staple foods for the ancient inhabitants of the Andean region. Amaranth Domestication Amaranth was probably widely used among hunter-gatherers in both North and South America. The wild seeds, even if small in size, are produced in abundance by the plant and are easy to collect. Evidence of domesticated amaranth seeds comes from the Coxcatlan cave in the Tehuacan valley of Mexico and dates as early as 4000 BC. Later evidence, like caches with charred amaranth seeds, has been found throughout the US Southwest and the Hopewell culture of the US Midwest. Domesticated species are usually larger and have shorter and weaker leaves which make the collection of the grains simpler. As other grains, seeds are collected through rubbing the inflorescences between the hands. Use of Amaranth in ancient Mesoamerica In ancient Mesoamerica, amaranth seeds were commonly used. The Aztec/Mexica cultivated large quantities of amaranth and it was also used as a  form of tribute payment. Its name in Nahuatl was huauhtli. Among the Aztecs, amaranth flour was used to make baked images of their patron deity, Huitzilopochtli, especially during the festival called Panquetzaliztli, which means â€Å"raising banners†. During these ceremonies, amaranth dough figurines of Huitzilopochtli were carried around in processions and then divided up among the population. The Mixtecs of Oaxaca also recognized a great importance to this plant. The precious Postclassic turquoise mosaic covering the skull encountered within Tomb 7 at Monte Alban was actually kept together by a sticky amaranth paste. Cultivation of amaranth decreased and almost disappeared in Colonial times, under the Spanish rule. The Spanish banished the crop because of its religious importance and use in ceremonies that the newcomers were trying to extirpate.

Innovations and inventions of the 20th century Essay

Innovations and inventions of the 20th century - Essay Example Not only do they try to educate the people on the pros and cons of technology, they also provide solutions on how to minimize its effects on the environment as well as to the lives of the people. Additionally, the invention of the cell phone is equally influential to artists as they discuss the effects that cellphones have on the lives of the people. Some of the artists try imagining of the days when there were no computers or mobile phones, then compare life then and today (Janssen and Anne 12). The computer is one of the most influential technological innovations of the 21st century that has revolutionized the art world and influenced artists in the era. The computer, designed to make work easier for people, has turned them into slaves (Janssen and Anne23). This is the main reason why artists use it as a topic of discussion in their work. The internet is yet another innovation of this century that has influenced artists’ work and activities (Pilcher 470). They look at the advantages and disadvantages of the internet, especially the privacy and authenticity of information available on the internet. While researching, I realized that the audience plays a big role in creating art. The audience inspires artists in their work, especially in the kind of information presented in the artwork. Additionally, I realized that most of the artists today draw their inspiration from the artists of the impressionism. I awed at the impact of these artists have on art today, despite being regarded as failures in the French exhibition gallery. Janssen, Lisa and Anne Nigten.

Communication Theories Essay Example | Topics and Well Written Essays - 3500 words

Communication Theories - Essay Example In professional practice, communication is a sensitive tool that defines the relationship between employers, employees and the customers and the attitude that they have for one another. Consequently, the professional environment requires effective communication mechanisms to build a conducive social environment for every person and ensure an effective flow of information. The purpose of this paper is to analyse the extent to which communication theories illuminate areas of professional communication practice. Communication theories have attempted to provide an abstract explanation of the various elements that define an effective communication process as one way of modelling competence in communication. Whether an individual intends to relay information, persuade, trigger a response, or explain a phenomenon, the choice of the mechanisms of information flow and communication techniques will determine the success of the intended purpose of communication. Most scholars have arrived at a concession that the choice of word, media and the channel will be determined by the kind of communication, either social or official, and the audience that receive the information (Emory, 2006, p. 22). These dimensions of communication are all vital if an individual has to pass their information and be understood by their target audience, and this can only be measured by evaluating the response of the audience after the information has been propagated. One of the popular communication theories is the medium Theory of Communications that perceives the communication process as a message oriented process. As opposed to the information theory that perceives communication as a bidirectional linear process, the rhetorical theory provides an abstract of the communication process as a complete messaging loop. According to Sharma (2009, p. 11), the key element in any communication process is the message that is intended to be transmitted over to the audience and the feedback that the audienc e will provide. Message, may it be in speech or textual form, refers to the information that a professional intends to provide to relay to their audience. Competence in communication has been associated with the formulation of the message in such a manner that it is concrete, precise, clear, free of distortion and well-articulated. The design of a speech or a text message will depend on the choice of words, the intonation, non-verbal expressions and presentation techniques. Optimization of the properties that affect a message is vital as a failure of any of them will have a consequential impact on the entire communication process. For instance, even after the choice of the right words, the speaker may mess up the entire process by presenting in a low tone that the audience may not grasp the intended message. In a nutshell, the message is the central attention of any communication process and hence its organization and presentation is the core of effective communication. Another vita l element of the medium theory is the mechanisms of information transmission especially in the journalistic professional practice. A proponent of the medium theory, McLuhan predicted the evolution of the communication process with the proliferation of new technology where messages would need to be transmitted across the entire world. The medium refers to the channel of communication through which message is
