Article VIII What does it really mean essays

Article VIII What does it really mean essays Article VIII: What Does It Really Mean? required, nor excessive fines imposed, nor cruel and unusual punishment Excessive bail was borrowed with a few slight changes from the English Bill of Rights Act. The concept of bail in both England and in the United States was never thought as right to bail in all cases, but to provide that bail would not be excessive in cases where it is considered legitimate to set bail. The definition of Bail, as according to the Random House Dictionary of the English Language, property given as surety that a person released from custody will return custody will return at an appointed time. The concept of bail was first created by the Statute of Westminster the First of 1275 A.D., which created a detailed list of certain offenses that were bailable and those that were not. Because judges were permitted to imprison people with or without bail, the Petition of Right was enacted in 1628 A.D. Due to various frauds of petitions for habeas corpus which could not be presented the English Parliament enacted the Habeas Corpus Act of 1679 A.D., which established procedures for the release of prisoners from prison and created penalties for judges who did not comply with the Act. As a result of this, the judges then set bail so high, that it could not be met. With this Parliament responded by including in the Bill of Rights of 1689 A.D. a provision that excessive bail shoul d not be required. In America excessive fines were given meaning during the early part of the twentieth century. In an early case, the Supreme Court held that it had no authority to revise the sentence of an inferior court, despite the fact that the excessiveness of the fines were quite apparent on the face of the records. With the inability to pay, the poor were then sentenced to jail and thus giving meaning to the term ''excessive fines'' as it applied to the person sentenced. During the time the Eighth Amendment was adopt...

Are You An Introvert Or An Extrovert What It Means For You

Are You An Introvert Or An Extrovert What It Means For You Extroverts  are born to socialize. They feed off the energy of others and  don’t particularly enjoy  alone time. Introverts, on the other hand, are  quite the opposite. They enjoy spending time alone and use that alone time as an opportunity to recharge their batteries. But what are the key differences between an extrovert and an introvert, and what do they mean for you?

How Significant Was Kevin Rudd's Apology to the Stolen Generations Essay

How Significant Was Kevin Rudd's Apology to the Stolen Generations - Essay Example It was a very strong political expression that the country expressed towards the acknowledgement of fundamental human rights. The apology statement had very relevant political and social implications on Australia and the outlook of the country towards its indigenous populations. These implications stretch beyond the geographical boundaries of the country as the issue was discussed by the civil society all across the world. The objective of this essay is to analyze the significance of Kevin Rudd’s Apology to the Stolen Generations. Background of the apology The apology was a political statement which had been awaited for many years. Indigenous children and children of Torres Strait Islanders were forcefully separated from their families by the Australian government. The justification that the Australian government had for this act was the desired objective of upward social mobility and exposure of these children to the predominant modernized culture of Australia (Haebich, 2011) . These children were later referred to as the ‘Stolen Generation’. An enquiry commission The Human Rights and Equal Opportunity Commission, headed by Mick Dodson and Sir Ronald Wilson, was setup to undertake the â€Å"National Inquiry into the Separation of Aboriginal and Torres Strait Islander Children from their Families† (Haebich, 2011 p. 1033). ... 1033). The expression ‘Lost Generation’ is justified by the large percentage of children who were deprived of their parents and living systems. The report shed light to disturbing facts that these children were unhappy in the foster homes, institutions and adoptive families they were put in (Haebich, 2011, p. 1033). The report also contained evidence of forced labor imposed upon these children. The extensive interviews, conducted by the enquiry commission, observed consequences of separation which included medical and psychological issues, addiction, violence, self harm and even suicides (Haebich, 2011). In light of all these observations there was pressure on the Australian government both from within the country and human rights movements across the world. Moreover, out of the 54 recommendations made by The Human Rights and Equal Opportunity Commission, one was that the Australian government must apologize to the stolen generation (Haebich, 2011). Since then, this has been a matter of political debate for all the governments which came to power in Australia. In other words, the apology was much awaited by the world. The Political Importance of the Apology The decision of Kevin Rudd to apologize to the Stolen Generation has its importance as a strong political expression. It must be noted here that after the report thoroughly asserting the need of the apology was published, it was denied for 11 long years. No governments owned up the moral responsibility towards the Stolen Generation and the human rights violations faced by them. The general Australian response to the report was that the observations were inflammatory (Haebich, 2011, p. 1033). There was also

A Human Disorder, Involving Dysregulation of Epigenetic Mechanisms Essay

A Human Disorder, Involving Dysregulation of Epigenetic Mechanisms - Essay Example A lot of people having this condition are born with an aperture in the abdomen wall that facilitates the protrusion of the abdominal organs through the navel. Many infants with BWS have tongues that are abnormally long (macroglossia) which can interfere with swallowing, breathing, and speaking. BWS’s other features include abdominal organs that are abnormally large (viscreromegaly), pits or creases in the skin near the ears, kidney abnormalities, and low blood sugar (hypoglycemia) in infant (Baum, et al, 2007 pg 78). The genetic causes of BWS are complex. It results from regulation of genes that is abnormal in a given region of chromosome 11. People usually inherit a single copy of this chromosome from each parent. In many genes of chromosome 11, each of the two copies of the genes is expressed (turned on) in the cells. However, for some genes, only the gene inherited from the father (paternal copy) is expressed while for some, the copy inherited from the mother (maternal copy) is the only one expressed. These parent specific differences in the expression of the gene are caused by genomic imprinting phenomenon. Abnormalities which involve genes on chromosome 11 that experience genomic imprinting are the cause of many cases of BWS. Typically, half of the cases are at least caused by changes in the methylation process. In genes that experience genomic imprinting, methylation is among the ways that parents of the gene of the origin are marked at the time of the creation of the egg and sperm cells.

2011 Occupy Wall Street Movement Research Paper

2011 Occupy Wall Street Movement - Research Paper Example It raised questions about the humanity of the people at the helm of affairs and also questioned the political will of the nation’s system of governance whereby the sincerity of the nation’s political establishment in creating a certain amount of parity within the population is rendered suspect. There are other aspects of this movement and the government’s response that need to be looked into. Apart from not offering any tax sops to the common man and talks of doing away with tax-cuts that were offered during the Bush-era, the government had fuelled the anger of the common man. The brutalities that were carried out upon the protestors by the police came out in the open only due to the work of independent cameramen who were not associated with any news agency. The incidents that occurred during the movement thus bring to light the role of the media as well in the success or failure of such movements. The movement is described by itself as being the result of a series of movements that supports democracy. These, the movement claims, includes the uprisings in Tunisia and Egypt where the common man protested against the marginalization of a majority of the population for the purpose of the welfare of the minority that constituted the ruling elite (Occupy Wall Street : The Revolution Continues Worldwide, n.d.). Having this as a moral backing definitely provides a cushion for the movement in terms of the support that it would be able to gather at an international level. There is thus an element of diplomatic support that the supporters of the movement expected to get through their efforts for an equitable society in which everybody would be provided with equal opportunities. In the absence of this, people would live lives whereby their work would be used for the benefit of others and not themselves. Apart from the moral degeneracy of this position, there is also the fact of its unsus tainability from an economic point of view that needs to be looked

Dentistry in Developing Countries DENTURE CAMP-AN EXPERIENCE BEYOND IMAGINATION Short Title-Gundlupete Denture Camp Abstract Aim: Main aim of dental camp is awareness, education, and motivation of the common man regarding his/her dental health. This report presents the efficient way of conducting a denture camp and tackling the short comings faced during the course. Methods :When treating a vast population in camps, it calls for more number of instruments, equipments and lot of manpower in terms of doctors, dental mechanics and supporting staff. 110 patients were selected for the denture camp. They were informed to come early morning at 8a.m on the scheduled date and make necessary arrangements for their stay for one night during the camp as the most of the patients were from surrounding villages. Discussion: Dentures are no more a luxury; it has become a necessity for the edentulous patients for the basic health maintenance. Many problems were encountered during this camp. Though there were so many hurdles doctors became successful in treating the patients. Conclusion: The team had taken a brave step with all the problems and they ended successfully. In spite of all the problems faced, the dedicated team work proved fruitful in rehabilitating 132 patients in short spans 24 hrs. The efforts of team were highly appreciated by the people. Keywords: Dental Camp, Dentures, Public health. INTRODUCTION Dental Camps in India are being routinely conducted. The main objective being awareness, education, and motivation of the common man regarding his/her dental health. Dental camps usually are conducted for a large population who do not have accessibility for a sophisticated dental treatment and for the people with financial constraint. Camps can be conducted for screening or for treating the patients like extractions, restorations and/or fabrication of dentures. Screening and treatment camps held for extractions, restorations does not require a lot of equipments and man power on the other hand; fabricating a denture for the patients require a lot of equipments and instruments. When treating a vast population in camps, it calls for more number of instruments, equipments and lot of manpower in terms of doctors, dental mechanics and supporting staff. Public health work exhibits a certain number of characteristics that are different from individual practice in the same field. Most important is the fact that the public health work must be done in areas where the group responsibility is recognized. Another characteristic of public health method is its reliance upon the team work. This is due to the necessity of efficient handling of large group of people. This report presents the efficient way of conducting a denture camp and tackling the short comings faced during the course. Materials and Methods A denture camp was conducted by the Department of Prosthodontics, Government Dental College and Research Institute Bangalore, at Gundlupete, Chamarajanagar distric on 9 and 10th of Feb. 2013 Gundlupete, is a small town with a population of 28157 situated 200 kms from Bangalore. The villagers are hailing mostly from poor families, with a very limited knowledge and accessibility to their basic health maintenance needs, especially dental health. For this reason this particular village was chosen by the Department of Prosthodontics, Government Dental College and Research Institute, Bangalore to render denture services to the poor and needy patients. Indian Medical Association Gundelpet took the responsibility to provide the services, like accommodation and food for the team. An announcement of the denture camp was made in the village by a local body one month prior to the scheduled date of the camp. Audio aids like public addressing systems/microphones and visual aids like pamphlets were used for the public awareness regarding the camp [1]. Enlightening the people about the Dental health is a must in such a town, so awareness was made. People were instructed through these aids to attend the preliminary screening which was held on held on 9th Jan 2013 for which a team of doctors with required diagnostic aids were deputed from the college. It is an achievement in the history of Government Dental College and Research Institute for having screened 300 patients. Out of 300 patients, 110patients were selected for the denture camp. They were informed to come early morning at 8a.m on the scheduled date and make necessary arrangements for their stay for one night during the camp as the most of the patients were from surrounding villages. The doctors had so much o f keen interest to render the services for selected 110 patients who had come from different parts of the village. A list of all the necessary equipments, materials and instruments with their quantity was made for the fabrications for 125 dentures. Required materials and equipments were collected from the college stores. Chair-side instruments, diagnostic instruments, lab equipments were collected from the staff and students of the Government dental college and research institute. A total of 100 clamps and flasks and 115 articulators were procured. Ten micromotors were collected, of which 5 were from the department and the rest were borrowed from the other departments. Local organization was so kind enough to take the responsibility of providing two gas cylinders for the lab-work. 4 â€Å"T† attachments containing 10 burner gas connection points each were taken from the Department. The collected materials were sorted out in an orderly manner and were packed in the cartons. There were 20 cartons containing equipments and materials. These cartons were numbered and a list containing all mater ials in a particular carton was made and pasted on each of them. A copy of the same was made and kept with a particular volunteer for easy access and to avoid confusion. 3 mini buses containing a team of 55 dentists, 55 dental mechanics and five supporting staff left to Gundlupete on 8 th morning . The dentist’s team consisted of staff including the Dean cum Director, Post Graduate students of the department and the house surgeons from various other departments who volunteered to be a part of this denture camp. The dental mechanics team consisted of dental mechanics from our institution and also from various other dental colleges. After reaching the camp venue ( primary school in gundlupete) rooms were selected for the clinical work, one for the lab work and plaster work was carried out in the open ground in front of the class rooms. Plastic chairs for seating the patients, tables for the dental technicians, gas assembly, huge containers for dewaxing and acrylization were arranged on the same evening. On the 9th morning the camp started at around 8 a.m. All the patients were registered and were given a token to come in queue to avoid confusion. On the token the patients register number and all the clinical steps involved in the denture fabrication with the assigned Doctor’s and technician’s name were mentioned. Along with each mentioned clinical step, space was provided to indicate the step which has been completed for the patient. Dentist and technicians were divided into 11 groups comprising of 5 dentists and 5 technicians in each group. Primary impressions for all the patient’s were made with high fusing impression compound and subsequent wash impression with irreversible hydrocolloid were made. For the patients with poor alveolar ridges special tray were fabricated, border molding was done using putty and subsequently secondary impressions were made with Zinc oxide eugenol. All the primary impressions were numbered according to the number given to the patient. The same numbers were transferred on the casts. Record bases were fabricated using shellac base plates. Occlusal rims were fabricated on the record bases using modeling wax. Lost Occlusal vertical dimension and centric relation were recorded using a static method and shade selection was done. Teeth arrangements were done by the technicians. The try-in was done and the trial dentures were returned to the technicians for the acrylization. Then the patients were asked to come next day morning for denture insertion. Once the patients were dispersed the dentists also joined the technicians for the lab work like sealing of the trial dentures, flasking, dewaxing, acrylization, finishing and polishing procedures. The register numbers were incorporated in the dentures during the trial closure. The whole team worked till all the dentures were processed which went on day and night without taking rest, the team of doctors did not sleep at all, on such herculean line worked till rising of the sun. Deflasking, trimming, finishing and polishing of the dentures were done the following day. All the required chair side trimming was done and denture insertion was carried out. Post insertion instructions were given to the patients in groups and the written format was distributed to each of them. Most of the dentures had satisfactory retention and stability. Patients were comfortable and satisfied. One or two patients who had compromised retention in their dentures due to poor alveolar ridge were instructed to use the denture adhesives. The patients were advised to come after a week for the follow up for which a team of three dentists was deputed from the college. Some of the patients had developed soreness which was relieved and some minor occlusal corrections were carried out. Discussion In developing countries like India , majority of the population lives in villages were providing basic health facilities is a Herculean task. The worldwide prevalence of dental disease is a constant reminder of the almost universal need for effective dental health programmes. These programmes should be routinely conducted for the betterment of the patients. Conducting a successful camp, especially denture camps include assembling the manpower, finance, materials, equipments, instruments, coordination and generous mind of the team. Denture camps unlike the routine camps, require a lot of time, effort, equipments and co-ordination. Treating the edentulous poor patients in camps provides them with dentures which they cannot afford due to financial constraint. Through these camps it is possible to rehabilitate more number of poor patients in short span of time. Rehabilitating the poor edentulous patients improves their appearance, confidence, health and overall well-being. Further, the quality of treatment provided may not be of high standards as all the clinical steps cannot be done due to time constraint, but the treatment given was the stepping stone to make them know the importance of teeth hygiene and to avoid further complications. Active participation of the local organization is very important for the success of the camp. They play a key role in informing and throughing light on their souls how important the camp was to save them from further decay in life. Arranging the venue for the camp, accommodation and food for the team, should also be taken care by the local bodies for a camp to be successful. Success of the camp depends upon the support and co-ordination of the local bodies. Problems were faced as we had only 100 clamp and flasks, the denture processing steps had to be repeated. The number of patients exceeded our estimate, because of which we informed the unregistered patients to undergo the treatment next time. Conclusion Dentures are no more a luxury; it has become a necessity for the edentulous patients for the basic health maintenance. Denture fabrication in a camp requires lot of efforts, manpower, equipments, coordination and support of the local body. Many problems were encountered during this camp. Though there were many hurdles but the doctors became successful in treating the patients. The mountains may look high, but when we begin to climb and reach the top we say it is not so high. The team had taken a brave step with all the problems and they ended with a happy note. In spite of all the problems faced, the dedicated team work proved fruitful in rehabilitating 132 patients in short spans 24 hrs. The efforts of team were highly appreciated by the people.

Computer Ethics Essay -- Ethics Morals Morality

Computer Ethics A Ten Commandments of Computer Ethics (see Appendix A) was first presented by Dr. Ramon C. Barquin's in his paper for the Computer Ethics Institute of the Brookings Institution entitled, "In Pursuit of a 'Ten Commandments' for Computer Ethics" in May of 1992. Computer ethics is about principles related to behavior and decisions made by computer professionals and users, including software engineers, operators, managers, policy makers, as well as educators and students. This means all these people involved should be supported with some "policies for ethical conduct" i.e. policies that guide their actions and increase adequacy of the decisions they make. (Szejko par. 1) With the rapid infusion of computers, software and related technologies into homes, schools and businesses, we initially focused our energies on learning about the technologies and how to use them. We now need to focus our attention on the ethical issues surrounding technology to insure that we and our children understand and practice values important to all of us; respect for others, their property, ownership, and the right to privacy. (Alden par. 4) There are various interpretations of the term "computer ethics." Computer ethics might be understood in one sense as the efforts of professional philosophers to apply traditional ethical theories and concepts to issues regarding the use of computer technology. However, it is possible to construe computer ethics in another sense to include standards of professional practice, codes of conduct, and aspects of computer law, public policy, and corporate ethics. Information technology has affected our home life, our business life, and our relationships with others. It has also affected us in regards to ... ... Respect For Your Fellow Humans.

Periodic Table Research Task

Periodic Table Research Task By Kevin Shaji Part A. You are to research the task below and submit as a written piece of work i) John Dalton proposed his atomic theory in 1808. Outline his theory. (4 marks) ii) Explain which part of Dalton’s atomic theory was later found to be incorrect. (3 marks) iii) Dalton developed a way to measure the relative atomic mass of the different elements. Using examples research and describe the meaning of the term ‘relative atomic mass’. (3 marks) i) 1) Elements are made up of tiny particles called atoms. 2) Atoms cannot be destroyed or created but can be rearranged during chemical changes. ) Atoms of a particular element are identical in mass, size, shape and other properties. 4) Atoms of different elements are different in their mass, size, shape and other properties. 5) Atoms cannot be divided into smaller particles. 6) Atoms of different elements combine in small whole-number ratios to form compounds. ii) 1) One part of Daltonâ €™s atomic theory that was later discovered to be incorrect was the part where atoms could not be divided into smaller pieces. New research has proved that atoms can be sub-divided into sub-atomic particles like protons, neutrons and electrons. ) Due to the discovery of isotopes it has been discovered that atoms of the same element are not exactly identical. They have different masses due to the number of neutrons. 3) Also it has been discovered that different elements have the same mass. These elements are called isobars. 4) It has been recently discovered that atoms can actually be destroyed by fission processes in atomic reactors or by atomic bombs. 5) Another defect in Dalton’s atomic theory is that not all compounds have small whole-number ratios. They can actually have large whole-number ratios as well. ii) The relative atomic mass is defined as: â€Å"the average mass of the isotopes in a naturally occurring sample of the element, taking into account the proportio n of each isotope present. † The symbol for relative atomic mass is Ar. For example naturally occurring chlorine has two isotopes Cl-35 and Cl-37. Cl-35 has a relative abundance (which is the percentage of that isotope on Earth in relation to the total abundance of the atom on Earth) of 75% while Cl-37 has a relative abundance of 25%. To calculate the Ar you must put the above into a formula. Ar= (75/100? 35) + (25/100? 37) =35. Another example of calculating relative atomic mass is: For an element E with the naturally occurring isotopes aE, bE, cE, and with the respective abundances of A%, B%, C% etc, the relative atomic mass (Ar) = (A/100 x a) + (B/100 x b) + (C/100 x c) Part B Leucippus Leucippus was an early pre-Socratic ancient Greek philosopher who lived sometime during the 5th century BCE. Not much of Leucippus early life is known due to the fact that not many of his dates were recorded. What we do know is that he was an Ionian Greek that studied at an Ionian school of naturalistic philosophy.At around 440 BCE Leucippus founded a school at Abdera, which his famous pupil Democritus attended. Around this time he proposed the theory of atomism. According to this atomism, the universe is composed of two elements: the atoms and the void in which they exist and move. This theory was later explained in much greater detail by his pupil Democritus. Leucippus contributed indirectly towards the development of the periodic table since he proposed the first idea of atoms. Thanks to his ideas the foundation for the periodic table was possible. Without his ideas the way we view the world may be completely different.Democritus Democritus was an influential pre-Socratic ancient Greek philosopher who lived from circa 460 BCE to circa 370 BCE. He inherited his father’s vast fortunes and used it to travel the world and visit many countries on his quest of knowledge. During these trips he met many scholars who taught many lessons. When he finally came back to h is native land he became interested in natural philosophy. At the around 440 BCE he became associated with a school in Abdera, which was founded by Leucippus, his mentor. His teacher was the first one to propose atoms, but Democritus later adopted this into his own atomic theory.His theory stated that everything contains tiny particles called atoms and that they were indivisible. He hypothesised that these atoms cannot be destroyed, that they were invisible that they were always and moving. He also stated and that they differ in size, shape, mass, position, and arrangement. Democritus contributed indirectly to the development of the periodic table. His contribution helped people to understand what an atom was and helped other scientist’s further look into science of the atom, which in turn led to the creation of the atomic table. AristotleAristotle was an ancient Greek philosopher who lived from 384 BCE to 322 BCE. He was the student of the ancient Greek philosopher Plata and the teacher to one of the greatest military commanders in the world Alexander the Great. He taught many subjects including physics, metaphysics, poetry, theatre, music, logic, rhetoric, linguistics, politics, government, ethics, biology, and zoology. He is considered to be one the most important figures in Western philosophy due to his writings encompassing morality, aesthetics, logic, science, politics, and metaphysics.One of his most well-known theories is that all mater is made from five elements. These elements are fire, water, air, earth and the fifth element aether. He believed all matter was made from a combination of the four elements except the stars and planets which are made of the fifth element aether. Even though Aristotle’s theory was wrong he contributed indirectly to the periodic table. The periodic table consists of elements and he hypothesised that elements exist. John Dalton John Dalton was an English chemist, meteorologist and physicist. He was born on th e 6th of September 1766 and died on the 27th of July 1844.He began to study at a local village school and at the age of 12 began to teach there. At the age of 15, he began to teach at a Quaker school in Kendal. After teaching here for 10 years he moved to Manchester as a teacher. While there he joined the Manchester Literary and Philosophical Society, which provided him laboratory facilities. The first paper he presented was about colour blindness which he suffered from. Dalton arrived to atomism by his fascination of meteorology. Dalton stated that the forces of repulsion thought to cause pressure acted only between atoms of the same type.From here on he proceeded to calculate the atomic weight of atoms from percentage compositions of compounds. After this he developed his own atomic theory, which completely revolutionised the way we see the world today. Dalton contributed indirectly to the development of the periodic table. Dalton’s information on atomic weights was a huge factor in the creation the periodic table. He also proposed a chemical symbols for some elements. Without Dalton’s ground-breaking work the periodic table would not be possible. Johann DoberienerJohann Wolfgang Doberiener was a German chemist who was born on the 13th of December 1780 and died on the 24th of March 1849. Doberiener had little opportunity for formal schooling, and so he was apprenticed to a pharmacist. He began to read widely, and attended scientific lectures whenever he received the chance. In time he became a professor at the University of Jena in 1810. During the period of 1815-29, Johann Doberiener arranged elements in order of their atomic weight. He sorted these elements into groups of three, which became known as the law of triads.He arranged them according to the atomic weight of the middle element to the average atomic weight of the remaining two. Doberiener contributed indirectly toward the development of the periodic table. Though his method was disca rded due to the fact it didn’t apply to all the elements, Doberiener gave rise to new ways to classify the elements which greatly helped in the creation of the periodic table. John Newlands John Alexander Reina Newlands was an English chemist who worked on the development of the periodic table. He was born in London on the 26th of November of 1837 and died on the 29th of July 1898.He did not study at a normal school but was rather home schooled by his father. He went on to study at the Royal College of Chemistry. In 1863, he set up a practice as an analytical chemist and in 1868 he became the chief chemist at James Duncan’s London sugar refinery. He later left this profession and in 1864 published his concept of the periodicity of the chemical elements. He arranged all 62 elements (known at the time) into a table based upon the ascending order of the atomic weights. He observed that every 8th element in his table displayed similar properties.He named this discovery the Law of Octaves and stated that an element exhibits behavior that is similar to the eighth element preceding/succeeding it. John Newlands contributed indirectly to the development of the periodic table. Even though Newland’s table was not accepted, his work helped to lead Mendeleev (the father of the periodic table) on the right track thus greatly contributing to creation of the periodic table. Dmitri Ivanovich Mendeleev Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He was born in Siberia in 1834 and died in 1907.He is considered the father of the periodic table because he created the first version of the periodic table of element and used it to predict elements yet to be discovered. In 1849 his family relocated to St. Petersburg and Mendeleev entered the Main Pedagogical Institute in 1850. He studied science there and graduated in 1856. In 1863 Mendeleev was appointed to a professorship in the University he studied in. In 1864 Dmitri Mendeleev produced his g reatest achievement: the periodic table of elements. He arranged the 66 elements known at the time by their atomic weight.By doing this he managed to organise them into groups possessing similar properties. If a gap existed in his table, he anticipated that a brand new element would one day be discovered and he predicted its properties. Some of the elements he predicted were later found and provided great evidence towards the accuracy of his table. Dmitri Mendeleev contributed directly towards the development of the periodic table since he developed it. Mendeleev’s original periodic table of elements is the model of the modern day periodic table of elements and thanks to his discovery we have a greater understanding of the universe. Henry MoseleyHenry Gwyn Jeffreys Moseley was an English physicist who was born in England on the 23rd of November 1887 and died on the 10th of August 1915 at Gallipoli. As a young boy Moseley studied at Summer Fields School where he was awarded a King’s scholarship to attend Eton College. In 1906, Moseley entered Trinity College of the University of Oxford, where he earned his bachelor’s degree. In 1910, Moseley began to study under Sir Ernest Rutherford. In 1913, he moved back to Oxford, where he was given laboratory facilities. While at Oxford, Moseley measured the x-ray spectral lines of nearly all the elements known at the time.The results of his study showed a clear and simple progression of the elements that was based on the number of protons in the atom’s nucleus, rather than the order based on atomic weights that was then the basis of the periodic table. Moseley contributed indirectly to the development of the periodic table. He discovered the atomic number of elements which revolutionised the way the elements were sorted. Now thanks to him the modern periodic table is sorted by atomic number. Timeline of The Periodic Table 440 BCE Democritus and Leucippus put forward the idea of the atom, an ind ivisible particle that all matter is made of. 30 BCE Aristotle proposes his theory about the four elements which are earth, air, fire & water. He also proposes a fifth element aether, which the stars and planets were made of. 360 BCE Plato coins term the term ‘elements’. 1605 CE Sir Francis Bacon published â€Å"The Proficience and Advancement of Learning† which contained a description of what would later be known as the scientific method which is the acquirement of new knowledge or the correction of existing knowledge. 1661 CE Robert Boyle published â€Å"The Sceptical Chymist† which was a written work on the distinction between chemistry and alchemy.It also contained some of the first ideas of atoms, molecules, and chemical reactions. 1754 CE Joseph Black isolated carbon dioxide, which he called â€Å"fixed air†. 1778 CE Antoine Lavoisier wrote the first detailed list of elements. The list contained 33 elements & differentiated between metals and non-metals. 1766 CE Henry Cavendish discovered hydrogen was a colourless, odourless gas that burns and can form an explosive mixture with air. 1773–1774 CE Carl Wilhelm Scheele and Joseph Priestly independently isolated oxygen. 1803 CE John Dalton proposed â€Å"Dalton’s Law† which described the bond between the components in a mixture of gases. 828 CE Jons Jacob Berzelius created a table of atomic weights and introduced letters to represent elements. 1828 CE Johann Doberiener developed groups of 3 elements with similar properties, which he called triads. 1864 CE John Newlands organised the known elements in order of atomic weights and observed resemblances between some elements. 1864 CE Julius Lothar Meyer develops an early version of the periodic table, with 28 elements classified by valence. 1864 CE Dmitri Mendeleev produced a table based upon atomic weights but organised ‘periodically’ with elements of congruent properties under each other.His P eriodic Table included the 66 elements known at the time, classified by their atomic weights. 1894 CE William Ramsay discovered the Noble Gases. 1898 CE Marie and Pierre Curie isolated radium and polonium from pitchblende. 1900 CE Sir Ernest Rutherford discovered the cause of radioactivity was decaying atoms. 1913 CE Henry Moseley discovered the atomic number of each of the elements which changed the way the periodic table was organised. 1940 CE Edwin McMillan and Philip H. Abelson discover neptunium, the lightest and first synthesized transuranium element, found in the products of uranium fission. 1940 CEGlenn Seaborg arranged the transuranic elements (the elements after uranium in the periodic table) below the periodic table making it easier to read.

Survey of Transport Geography essays

Survey of Transport Geography essays Pooley, Colin G., Jean Turnbull. Modal choice and modal change: The journey to work in Britain since 1890. Journal of Transport Geography, 8:11-24 In the chosen article the main idea was to show how since 1890 until present day how the journey to work using different transportation methods on a day to day basis has changed as technology has changed. Furthermore, to illustrate how changes in transportation policies have changed because of the modal change in transportation. It is ultimately related to the study of transportation geography because the article illustrates how the need for bigger and better infrastructure was needed to accommodate the modal change in ways people journey to work. The subject matter of the article is important because it focuses on the impacts of the industrial revolution on modes of transportation both in Britain and to a certain extent in the United States. It also addresses how policies affecting transportation had to change in order to keep up with the changing modes of transportation. It is also important because the information discovered in the article can also provide a basis for policies in developing countries in terms of infrastructure and regulations surrounding transportation. Some of the methods used in collecting the data on the changing structure of the journey to work were firstly, a survey of 1834 people who began working in 1890. Next 90 separate semi-structured interviews were conducted. Thirdly, and the largest group consisted of genealogists and family historians who where used in pervious study. Lastly, by placing advertisements at large employers and the local press to find people who were interested in the research and then setup interviews with those who were interested. From this style of research many problems and biases can occur, like those with more education and in higher status occupations would tend to respond to the advertisements. To correct this, the research ...

What do we owe each other in the social Contract Research Paper

What do we owe each other in the social Contract - Research Paper Example onfessing (assuming they wish to), they will be assured of punishment but by refusing to do so each of them is guaranteed a light one (Kreps et al., 1982). Ergo if each can depend on the other not to confess for the sake of them both, then it can be said they have a social contract in place. In the early part of this decade there has been a great deal of controversy and conflict in respect to the expectations of Americans from the social contract that has was established in previous generations (Edsall, 2013). There have been numerous complains for instant in the fast food industry with employees and employers at loggerheads over issues of minimum wage. In the 80’s and early 80’s for instance, the industrial social contract in the USA was characterized by companies that took care of their workers welfare and provided them with insurance cover and pension benefits (Lubchenco, 1998). As a result, they workers needed unions less and one could argue that the industrialist sacrificed their right to exploit workers and they in turn sacrifice theirs to agitate for better conditions than they were already enjoying through labor unions. There are other underlying issues that underpin the social contract challenge, for the first time in nearly half a century, Americ ans are forced to struggle with what they want to get from the social contract (Freedman & Lind, 2013). Retrospectively, it was founded on a premise of relatively high wages and reliable benefits; however today, the system is such that low wages are supposed to be offset by reduced consumer prices and government intervention. Explicably, there has been considerable disaffection with the state of affairs and this has necessitated a re-examination of what the social contract is expected to do for the people and how it is they seem to be getting a raw deal. Alan Krueger who is the chairperson of the Obama’s economic advisors posits that America has lost its ethical and moral moorings because of the

Countrywide - Essay Example Otherwise, the ratio dropped to -11.61 in 2007 due to the general depression that affected the global economy (Kaplan, 2011). We can attribute the drop to predatory lending prices and slow housing market. The company was involved in the strategies only to lead it into problems. It is important to recognize that the company experienced a low return on assets. Ethics is a major determinant for the success of any business organization. The company’s poor performance can be partly attributed to unethical practices that it engaged while trying to maximize profit and introduce new products (Kaplan, 2011). For instance, subprime mortgage is a loan given to people with low income taking advantage of their lack of understanding of terms of the loans. The company misled the borrowers that it had a fixed rate in order to attract more clients yet they new that the people could not afford. The strategy lowered reputation of the
