Is Royal Mail justified in offering and promoting its direct mail Research Proposal
Is Royal Mail justified in offering and promoting its direct mail services - Research Proposal Example Under the Postal Services Act 2000, the UK government decided to introduce Postcomm as the regulator of a universal framework designed to protect the customers from unreasonable price increase of post stamps and poor quality postal services such as delayed, damaged or lost letters and parcels. (Postcomm, 2008; BBC News, 2004) As part of increasing the efficiency of post mail services throughout UK, the local government decided to open the post mailing business to other private operators. (BBC News, 2004) In line with the growing competition in the post mail industry, the researcher will answer the research question ââ¬ËIs Royal Mail justified in offering and promoting its direct mail services?ââ¬â¢ by examining both the positive and negative impact of ââ¬Ëjunk mailââ¬â¢ under the British Royal Mail services. In the process of justifying the pros and cons of ââ¬Ëjunk mailââ¬â¢ services, the researcher will discuss the size of volume increase in direct mail; the commercial and social effects of increasing the ââ¬Ëjunk mailââ¬â¢ volume as well as the ecological effects of ââ¬Ëjunk mailââ¬â¢ services. There are pros and cons with regards to the delivery of ââ¬Ëjunk mailââ¬â¢ also known as the unsolicited or unaddressed commercial mails to households. To evaluate the benefits and consequences of junk mail, the researcher will discuss the following: According to the Local Government Association (LGA), roughly 78,000 tonnes of junk mail reaches the landfill sites each year. (Oliver, 2006) In 2005, as much as 4,002 million personal mails and 1,132 million commercial mails were distributed all over UK. (DMIS, 2006: 2) This figure reflects a 62% increase in Direct Mail in the last 10 years. (See Table I ââ¬â Direct Mail Volume 1990 ââ¬â 2005 on page ) The main social and commercial problem attached with the increasing volume of junk mail is the fact that not all households that constantly receive junk mail are reading the mails. As a major social consequence of increasing

Sustainable Energy and Power Systems - Coursework Example The advantage of Gaussââ¬â¢s law over Coulombââ¬â¢s law lies in the facts that, in a faraday cage, the electric field inside get demonstrated. The law makes use of Ampereââ¬â¢s law dealing with magnetism. On the other hand, Coulombââ¬â¢s law requires not only Gaussââ¬â¢s law in its derivation but also makes use of other Maxwellââ¬â¢s law (Fleisch 3). 3. Given that relative permittivity =3, and radius r3=2 cm. And permittivity of vacuum=8.85 pF/m, the potential difference between the surface of the conductive cylinder and the outer surface of the dielectric cylinder can be determined as followsà ; This refers to an electrical device designed to transmit power through the barriers of electrical apparatus. This apparatus may include transformers and circuit breakers. Also, be defined as an insulator, which refers to a barrier preventing conduction of electricity from one device to the other. Any bushing designed must be able to withstand high voltage generated by the electric power. In addition to this quality, the bushing must also be capable of withstanding mechanical forces and seal the conducting parts of a conductor well. As the current flows through a conductor, high electrical stresses act on the conductor and these can lead to breakdown in the electrical insulation (Fleisch 16). There exist different shapes of bushings with varying sizes and designed in different techniques. Two of the types include solid bushings and capacitance graded. The solid bushing consists of a cylinder made of an insulating material, for example, porcelain or rubber. At the centre, a ground barrier covering the conductor with a high voltage exists and its attachment done to the ground. The figure below shows the arrangement of the bushing explained above. The cylinders, which conduct the electric current, spread out the change in voltage evenly. The distribution of voltage in the conductor varies depending with the material. The graded capacitive voltage in bushings,

Social Change Essay Example for Free
Social Change Essay Social Change is defined as any modification in the social organization of a society in any of its social institutions or patterns of social roles. Usually social change refers to a significant change in social behavior or a change in some larger social system, rather than to minor changes within a small group. Thus, social change refers to changes in the established patterns of social relationships for example in family, religious or economic life. One of the biggest social changes that has happened during my lifetime is the development and distribution of cell phones. Ten years ago cell phones were never even heard of and now they seem to be a necessity to life. The first cell phones were made back in the 1980s and were the size of bricks. They were also costly so not many people had them. The first experience I had with a cell phone was when I was in 5th grade and my mom bought our familyââ¬â¢s first cell phone. It was a solid black flip phone that had a pullout antenna and a black and white screen. When my mom bought the phone my siblings and I thought it was the coolest thing in the world and we use to beg our mom to let us play games on her phone. A few years later, due to the ever growing popularity of portable phones, the rest of my family would be getting their first cell phones. I received my first cell phone when I was in 7th grade and most of my other friends were starting to get theirs. It was a solid red phone with a slide down keyboard and it was one of the more favorable cell phones at the time. When I bought the phone, I immedia tely noticed a big change for me and that was no longer having to remember peopleââ¬â¢s phone numbers. Instead of memorizing twenty to thirty numbers I could just program them into my phone and never have to worry about them again. By the time I entered high school, every kid had a cell phone and now it was a competition to see who had the best and most up to date cell phone. Since the invention of cell phones the technology and software of the phones have increased exponentially in such a short period of time. The biggest leaps in the phones technology happened when I was in high school. During my softmore year touchscreen phones came out and everybody had to have one.

The Inhabitants Of Wales History Essay
The Inhabitants Of Wales History Essay The most populous Celtic community in Great Britain are the inhabitants of Wales in the western part of England. The Welsh who call themselves Cymry and their country Cymru had been Christians long before the Angles and Saxons adopted Christianity and they are proud of their literary tradition the beginnings of which predate English literature. The motif of the red dragon in the Welsh flag is a symbol of the Welsh peopleà ´s resistance against Anglicization and of the perpetuation of their culture and language. The number of ethnic Welsh people is not known. As for the speech community of Welsh this accounts for 0.58 million speakers and they make up 21 per cent of the total population of Wales. Some 50,000 Welsh-speakers live outside Wales in other parts of England, most of them in the region of Greater London. The level of language maintenance has remained stable during the past two decades. Assimilation to English, though, has been a trend with continuity. About a hundred years ago there were still some 0.9 million Welsh speakers. Most speakers of Welsh live in the western and northern parts of Wales where the rates for language maintenance are between 40 and 50 per cent. In the South the level has fallen below 20 per cent. The Welsh language does not suffer from a lack of transmission to the younger generation like Scottish-Gaelic (> Highland Scots). In the youngest age range (i.e. between 3 and 15 years) Welsh is spoken by 32 per cent. Proficiency in Welsh is much lower in all other ag e groups, even among the older generation (i.e. 24 per cent in the age range, 65 and over). At the beginning of the twentieth century there were still 0.28 million Welsh people who could not speak English but only their native tongue. At the end of the twentieth century their number had been reduced to a minimum of 21,500 which is less than 1 per cent of the Welsh speech community. Those who speak Welsh are bilingual, speaking English as second language. Together with Breton in Brittany and Cornish, formerly spoken in Cornwall, Welsh forms the Brithonic subgroup of Insular Celtic (see Irish for the Goidelic subgroup). Already in the late sixth century, Welsh had developed local features which set it aside from other varieties of Celtic in Britain. The origins of Welsh literature are shrouded in the mist of medieval history. The works of two poets of the sixth century, Aneirin and Taliesin, mark the beginnings of a literary tradition in Welsh. Their literary works, though, are only preserved in manuscripts of the thirteenth century. It is assumed that the texts in the manuscripts are copies of much older originals. Highlights of medieval literature are the collection of narrative prose, the Mabinogion (eleventh thirteenth centuries), the codification of Welsh laws compiled by Hywel Dda (tenth century) and bardic lyrics composed by Dafydd ap Gwilym (thirteenth century). The translation of the whole Bible into Welsh was completed in 15 88. It appeared in a second edition in 1620, and its language became influential for the elaboration of a modern literary standard. Since the Welsh literary language continues language use of the seventeenth century it holds a bridging function between the modern and the ancient so that the connection with the medieval literature is not lost for the reader of today. Those Celtic tribes who had settled in Wales some two thousand years ago saw the advent of the Romans and experienced Roman rule over Britain. After the Roman conquest of Britain in 43 c.e. Wales was integrated into the Roman Empire as a region of military interest but Roman settlers did not come to live there. The Celts in Wales learned about Latin from the Roman administration but it was only during the time when Christianity spread over Britain that Latin became the vehicle of cultural and social innovation in the Celtic communities. The oldest layer of religious terminology in Welsh dates to the third and fourth century; e.g. eglwys à ´churchà ´ Medieval history is dominated by the struggle of the Celts in Britain against Anglo-Saxon supremacy. The historical king Arthur who has been acknowledged as the founder of the British lineage of kings rose to legendary fame as the protector of the Celtic Christians in their fights against the Germanic heathens in Britain. In the late eighth century, the king of Mercia, Offa, had an earthen wall built to separate the Celtic territory of Wales from the Anglo-Saxon settlements. For centuries, the Celts remained west of Offaà ´s wall and the Anglo-Saxons east of it. Wales was finally conquered in 1282 and annexed to England. The status of Wales as a region under the authority of the British Crown was formalized in 1536, and the monopoly of English as the language of administration was confirmed. The English rulers practised a policy of apeasement to avoid social unrest by exchanging privileges for loyalty and to accept the Welsh aristocracy into their service. The Welsh à ©lite was s upposed to adopt the English language and English lifeways as a precondition to keeping their privileges. One of the lineages of the assimilated Welsh à ©lite was very successful. These were the Tudors whose representatives eventually ascended the English throne. The first Tudor to rule over England was Henry VII (reigned 1509 1547). Until the eighteenth century, Welsh society was divided into an Anglicized à ©lite of Welsh descent, loyal to the kings of England, and Welsh peasantry whose lifeways remained practically untouched by English culture. The seventeenth century saw the introduction of a Protestant movement which has dominated religious life among the Welsh up to the present, Calvinistic Methodism. Things changed with industrialization evolving, a process which unfolded in three stages on a prolonged horizon of time, ranging from c. 1780 to c. 1900. The area of southern Wales was of particular interest because of its riches in coal. The opening of coal-mines triggered a migratory movement of greater parts of the rural population to the urban and industrialized centers of the South where assimilation pressure was strong and language shift to English was swift. The British Education Acts of 1870 and 1889 stipulated English as the only medium of instruction at all schools and on all levels of education (i.e. from primary to higher), and these regulations promoted radical Anglicization. The romantic, all-European interest in the preservation of the local heritage and the movement of national awakening of the nineteenth century found its concrete manifestation in the cultural activities of the Celtic Revival. In Wales, this led to the establishment of a cultural institution, the Eisteddfod (literally à ´sessionà ´), which was held for the first time in Aberdare in 1861. This is a sort of fair which offers a cross-section of all domains of Welsh culture and language, including literature, theater and the visual arts. The Welsh language has been a crucial issue in the process of social and political reforms since the 1940s. After four hundred years of a monopoly of the English language in administration in Wales Welsh was granted official status alongside English in 1942. This regulation first concerned only the use of both languages at court and was extended to the use of Welsh in regional and parliament elections, in 1967. Furthermore, a trio of Acts in the decade 1988-1998 provide a new statutory infrastructure and institutional context to enable social reform in education, language rights and governance, (Williams 2008: 124). Constituents of this network of reforms are the Education Act (1988), the Welsh Language Act (1993) and the Government of Wales Act (1998) which are the pillars of Wales as an autonomous region within the United Kingdom and which provide the statutory platform for a National Assembly for Wales, established in 1999.

Effect of Changing Concentration on the Order of Reaction
Effect of Changing Concentration on the Order of Reaction Title : An Investigation into the Effect of Changing the Concentration by Continuous Method on the Order of Reaction Planning A. Hypotheses I predict that the rate of reaction is influenced by the concentration of the reactants; and that the rate of reaction and the concentration of reactants decrease as time intervals increase. I predict that the order of reaction is affected or influenced by the concentration of the reactant. I also predict that the change in concentration of reactants affects the rate of reaction proportionately and hence, the order of reaction. Such that, if the concentration of the reactants is reduced by half, the rate of reaction will also decrease by a certain proportion. The reaction that will be analyzed in this experiment is between a metal (magnesium ribbon) and an acid (sulfuric acid). The reaction is shown by the chemical equation below: Mg (s) + H2S04 (aq) ââ â MgS04 (aq) + H2 (g) In this experiment, 0.15 grams of magnesium ribbon will be used in excess, together with 10 cubic centimeters of 0.3 M sulphuric acid (H2SO4). The continuous method will be used, where the metal is in excess and the reaction goes to completion. The volume of the hydrogen gas (H2) will be collected at a measured time interval of 30 seconds. These volume readings at the time intervals shall be recorded and analyzed. III. Background The rate of a reaction depends in part on the concentrations of the reactants. The rate at which a reactant or reactants is transformed into products is the change in concentration of the reactant or reactants with time, (Wilbraham, et.al., 1997). Mathematically, the rate can be expressed as: Rate = Change in Concentration of Reactants / Change in time The formula implies that the rate of disappearance of the reactants is proportional to its molar concentration. Hence: Change in Concentration of Reactants / Change in time = proportional to the concentration of reactants The reaction rate has to be experimentally determined. From the reaction rate equation, the order of reaction can be obtained. The order of reactions can be classified as zero order, first order, or second order, with respect to only one reactant. IV. Risk Assessment In this experiment, sulphuric acid (H2SO4), will be used as a reactant. Since it is a strong acid and is very corrosive, I will observe the following precautionary measures: Wear protective goggles for the eyes. Avoid pipetting the sulphuric acid by mouth. Avoid inhalation of sulfuric acid. Care in handling the acid should be observed. It should be prevented from being knocked over. V. Fair Test To ensure that the results that I will obtain in the experiment are reliable and accurate, I will observe the following: The volume measurements of the sulphuric acid reactant will be made very accurately by reading from the lower meniscus of the 10 cubic centimeter mark The bung will be securely and tightly placed to prevent the collected hydrogen gas (H2) from escaping. The weight measurements of the magnesium ribbon will be made very accurately. All materials will be thoroughly cleaned before each use in order to prevent contamination. The experiment will have 3 runs or replicates in order to attain a high reliability of results. VI. Procedure of the Experiment: Materials needed: Stopwatch for time interval measurements 100 cc gas syringe for the Hydrogen gas collection 100 cc conical flask for the sulphuric acid 100 ml graduated cylinder for measuring the sulphuric acid Analytical balance for measuring 0.15 grams of magnesium ribbon Procedure: 1. Set up the materials while making sure that they are thoroughly clean and dry. 2. Using a graduated cylinder, measure 10 cc of 0.3 Molar concentration of sulphuric acid. 3. Carefully weigh 0.15 grams of magnesium ribbon using an analytical balance to make sure that the weight measurement is accurate. 5. Put the 0.15 grams of magnesium ribbon into the conical flask with the sulphuric acid. 7. Measure the volume in cubic centimeters of hydrogen gas collected in the gas syringe at every time interval of 30 seconds. 8. Record the volume of collected hydrogen gas at each set time interval. 9. Make 2 more runs of this experiment by repeating steps 1-8 at every run. VII. Results. Below are the tabulated volume measurements at every time interval: Table 1: Volume Measurements for Run 1 The data in Table 1 were plotted in a graph below: Graph 1: Volume vs. Time (Run1) For Run 2, the data were obtained were tabulated below: Table 2: Volume Measurements for Run 2 The data in Table 2 were plotted in a graph below: Graph 2: Volume vs. Time (Run 2) For Run 3, the data were obtained were tabulated below: Table 3: Volume Measurements for Run 3 The data in Table 3 were plotted in a graph below: Graph 3: Volume vs. Time (Run3) All three graphs show the trend that as time increases, the volume of the reactant decreases, while the volume of the product increases. B. Calculation of the Concentration of Reactant From the reaction: Mg (s) + H2SO4 (aq) ââ â MgSO4 (aq) + H2 (aq) Concentration is measured in terms of Molarity, where Molarity is equal to the number of moles of solute divided by liters of solution: Molarity = No. of moles of solute / Liters of solution For Magnesium (Mg), 0.15 grams were added to sulphuric acid. The number of moles is equal to: weight in grams divided by the formula weight. Hence, the number of moles = wt. in grams / FW. Since 0.15 grams were used, 0.15 grams should be divided by the formula weight of Magnesium (Mg), which is 24. So: 0.15 grams / 24 = 0.00625 moles for Mg. To get the molar concentration, the number of moles will be divided by the volume of the solution in liters, which is 0.01. So, the molarity of Mg is : 0.00625 / 0.01 = 0.625 M For the sulphuric acid (H2SO4) used, the molarity is 0.3 M. The number of moles of H2SO4 used is determined by multiplying the molar concentration by the volume of solution in liters. Hence: 0.3 moles/L X 0.01L = 0.003 moles. From the chemical equation of the reaction, for every 0.003 moles of H2SO4 used, the same amount of moles (0.003) of hydrogen gas (H2) is given off. The molar concentration of the hydrogen gas evolved can now be determined for each respective time interval, by dividing the number of moles by the volume obtained. For run 1: The concentration of the product can now be calculated, using the formula for reaction rate, where: Molarity = Number of moles / Liters of solution The data for the concentration of the hydrogen gas are tabulated below: Table 4: Molarity of the hydrogen gas (H2) The molarity values tabulated above are plotted in the graph below: Graph 4: Concentration vs. Time (Run1) Graph 5: Concentration vs. Time (Run 1) Showing the Gradient of the Tangent Curve The rate of reaction was calculated by measuring the gradient of the tangent of the curve above, as depicted by the red line. Hence, the gradient of the tangent is equal to 0.12 ââ¬â 0.05 / 150 = 0.00046. From the rate equation, the rate constant (k) can be obtained by the formula: k = rate x [H2SO4]. So: k = (0.00046) / 0.3 = 0.153. The rate equation is: Rate = k [H2SO4] Rate = (0.153) (0.003) = 0. 000459 or 0.0046. Hence, this value is equal to the gradient of the tangent of the graph above. This shows that the rate is directly proportional to the concentration of the sulphuric acid (H2SO4). Table 5: Concentration of Gas Collected and Rate of Reaction (Run 1) The plotting of tabulated data above results to the graph below: Graph 6 Rate vs. Concentration (Run 1) The Rate ââ¬âConcentration Graph for Run 1 above shows that the concentration of hydrogen gas (H2) is directly proportional to the rate of reaction. Thus, the concentration of sulphuric acid (H2SO4) is also directly proportional to the rate of reaction, whereby, as the concentration decreases, the rate of reaction also decreases. Since the Magnesium ribbon is in excess, only the sulfuric acid can be allowed to change. Having it in excess is to make sure that its concentration does not change. Using the rate of reaction: Rate = k [H2SO4] And applying the rate equation to the chemical equation in the reaction: Mg (s) + H2SO4 (aq) ââ â MgSO4 (aq) + H2 (g) The rate equation is now: Rate = k [Mg] à º [H2SO4]à ¹. Since Mg concentration does not change in the reaction, it is the zero order. On the other hand, since H2SO4 is in the first order of reaction, the rate is directly proportional to its concentration, as measured in the experiment by the concentration of the H2 gas collected, the overall order of reaction is: 0+1 = 1. For Run 2, the table below shows its concentration. Table 6: Molarity of the Hydrogen gas (Run2) The table of Concentration and Time for run 2 gives the following graph: Graph7: Concentration vs. Time (Run 2) The Concentration ââ¬âTime Graph for run 2 above shows the same trend as in run 1, where it shows an inverse proportionality: as time increases, the concentration of the sulfuric acid ( H2SO4) decreases as measured by the concentration of the hydrogen gas (H2) collected. The rate of re

Organic Evolution Essay -- theory of evolution
We act like animals, we eat like animals, and we are animals. The many theories of evolution such as Darwin's theory of evolution prove to us that we choose to believe that we are not animals when we really are. Evolution is the sequencial process of change over periods of time, which shapes and establishes the formation of modern man. In referring to evolution, the word means various changes. Evolution refers to the fabrication and development of life on earth. "Organic evolution" is the concept that all living beings evolved from simple organisms and have changed throughout the periods of time to create many and various types of species. Organic evolution is better known as the "theory of evolution." There are three main theories of evolution, which are, the early theories proposed by Comte de Buffon, Baron Cuvier, and Lamarck, the synthetic theory, and the Darwin theory.In the 1700s, French naturalists, Comte de Buffon and Baron Cuvier concluded with the studies of fossils and comparative anatomy that life on earth had endured many changes through a long period of time. In the early 1800s, another French naturalist named Lamarck, proposed the first complete theory of evolution. He observed through his observations, depending on the extent to which the use of the structure, that an animal's body structure is able to change during its life span. He also noted that organs and muscles, which were used often, tended to become larger and stronger. On the contrary, the organs and muscles, which were used seldom, tended to become smaller and diminish. With these observations, Lamarck concluded that these characteristics were hereditary. Proposed during two decades, the 1930s and 1940s, the synthetic theory involved a group of scientists. The group of scientists included two American biologists, Russian Theodosius and German Ernst Mayr, and the British geneticist and statistician Ronald A. Fisher. Together, they proposed the synthetic theory which combined Darwin's theory of natural selection with the ideals of genetics. In 1808, French naturalist Chevalier de Lamarck contemplated a theory of evolution, although, his theory of evolution did not gain any recognition until 1858. In 1858, British naturalist Charles R. Darwin furnished his theory of evolution, also known as Darwin's theory. Along with Darwin's theory of evolution there early theories and t... .... The Neanderthal Man was a survivor. It had a cranial capacity, which was similar in size to modern humans. The Neanderthal Man had basic advances in life style. The Neanderthal Man made basic clothes and constructed tools of advanced design. The Cro-Magnon Man is regarded has the first fine artist on earth. Proof of this fine artistry is that of rich records of accomplishments in cave paintings, which Cro-Magnon made. He made these records From stone engravings and carved figures. Cro-Magnon amazingly spread to all habitable parts of the world. Modern Man, us, has learned from the teaching and evolvement of the Cro-Magnon. We have learned to grow our own food and domesticate our animals. In addition we possessed the control over the environment and created cites and established civilizations. We act like animals, we eat like animals, and we are animals. The many theories of evolution such as Darwin's theory of evolution prove to us that we choose to believe that we are not animals when we really are. With the amazing changes and evolvement our species has undergone and as the twenty first century approaches us, who knows what forms of evolutionary change will come of us.
