Psychology Topic is Genes and aging and Gottlieb contribution to this Essay

Psychology Topic is Genes and aging and Gottlieb contribution to this - Essay Example The process of aging has engaged the attention of people from time immemorial. People in the past generally did not include as a scholastic subject of inquiry. It was so obvious a facet of life that in the past people generally accepted it as a reality with which they have to cope up with. However, the desire to prolong life was very popular and a marketable thing, many charlatans and quakes occupied the field and various potions for prolonging life appeared in the market. Initially serious scientists did not venture to study the phenomenon for fear they will be mistaken to be a pseudo scholar. With the microscopic study of cell and genetics growing as an important subject aided by technology, aging also came to be studied. The role of genes in aging has been a forgone conclusion. But the insight into the importance of environment- interface in shedding light on development is one of the major thrust areas of Gottlieb's study. The present study is an examination of his contribution t o the process aging. Aging is the major hurdle to the quality of human life in affluent communities. The study of senescence can prolong human life, preserve health, prevent age related diseases and even might cure aging. Aging is assuming the dimension of a worldwide social and economic problem. However, some scientists feel this area should get more priority and funding (Miller, 2005). The study of senescence, while it is part of the global quest to address this problem facing humanity, is also a dream of achieving the experience of an infinite universe. What is aging Aging came under the purview of scientific enquiry only in the early part of the present century. We are all aware of aging in humans from our earliest years, through normal, daily contacts with family members, neighbors, and others who have reached an advanced age. Perhaps because aging seems such an intuitively obvious phenomenon, it was quite late in becoming an object of formal study (Clark, 2002, p. 3) However there has been, over the centuries, an ardent attempt to unearth the magic elixir that would prolong life or even confer immortality. The process of aging was so obviously present in the conscious mind that no one thought it worth the trouble to go in depth to study what aging is. Aging has many external visible signs, as well as the changes in the mind and in the molecular level. The external changes also psychologically impact the person as he or she becomes aware that time is approaching for saying adieu. There are also degenerative changes associated with age, which are the results of alterations in the cardiovascular system. Humans also are under higher risk from external sources due to the slow collapse of the autoimmune system of the body. The reproductive capacity also diminishes along with aging and in the female this process sets in faster than in the male. In fact there are a spectrum of changes associated with old age but there is no uniform pattern of occurrence for all humans nor is there any fixed time when aging sets in all people. Some people are old at forty but there are septuagenarians who are fit as a fiddle. In some, mental faculties are impaired with age while bodies remain

National Buy Nothing Day Essay Example for Free

National Buy Nothing Day Essay ​A hard-working, single mother receives her pay-check that to her horror reads a measly $225.30. She doesnt use the money for her, instead she uses that money to care for her two children, she needs to pay the rent, and the electricity but her kids need food to grow. As she heads to the bank to cash the check she passes the neighborhood local store and no cars are outside and the light are dim. Nothing comes to her mind as to what seems different, she proceeds to head over to the bank, and notices that there is no clerks and no long lines? So many things run through her mind so she parks her beat-down car, that clanks and rattles. As she becomes even more worried there is a bright white paper that reads, Due to the over-consumption rates, the government has issued a National Buy Nothing Day, we are sorry for any inconviences. Her world is instantly shut down and she becomes scared as to how she is going to feed her children. This is exactly what I fear will happen if a National Buy Nothing Day is issued, so in my opinion, a National Buy Nothing Day would be a bad idea. ​A National Buy Nothing Day would become a huge inconvenience to many people over the world. Many people in the United States work minimum wage jobs and have a family to care for. 75% of the population works pay check to pay check just to give the basics to their family, and majority of the money is spent on food that they hope will last them the whole month until they are paid again. Sadly, more times than you would like to see parents unhealthy and always tired because they put their children before themselves, and what if the National Buy Nothing Day just so happened to fall on pay day. The heartbreak that would radiate from the couple, and the worry that rushes through their mind as to how they are going to feed their kids tonight and when t hey are going to be able to come back and cash that paycheck? Now that the parents view is shown, imagine the reaction of the kids that come home and see that there is no food on the table and the have to be told from their parents tha t they have to go to sleep hungry tonight. Thats heartbreaking for anybody, and everybody. ​Along with an inconvenience to many Americans, a National Buy Nothing Day would hurt the life of a teenager, very significantly. Teenagers  are the main percentage of individuals that add to the rate of over-consumption. Even though they are the big spenders in this era, they often rely on the quick stops to help them proceed with their school day. 8 out of 10 teenagers have a car in high school and with having a car comes a huge cash flow. Many teens can barely wake up in time to go to school and this often leads to them not eating, and scientists have proven that this can greatly affect their performance with anything they do in the day. So they make a quick stop at either McDonalds, or in New Mexico Blakes Lotaburger for a quick burrito, so they can eat something to fuel their bodies for the day. High school athletes rely on eating more than anyone, because they need that fuel to burn off, either at their zero-hour basketball practices or their afternoon football practice. So, the Buy Nothing Day would send these athletes hungry to school and the only thing they will eat is their lunch, and with starting school at 7:00 and not even eating until 12:00, thats a 5 hour long span of lacking concentration in class. ​Medication is more times than others bought on a daily for many individuals with medical problems and the vast majority of this is children. 30% of individuals die annually because of lack to medications that can save them, and 10% of them are children. Thats almost half the percentage! Children are more venerable to illnesses and harsh sickness than adults due to the fact that their bodies are still developing. What if on the National Buy Nothing Day that one child that has for instance, epilepsy, runs out his precious medication that prevents seizures. At any moment in the day he could experience pain in their head and in a blink of an eye, they are having a seizure. On the daily, 2/3 children die a day from seizures and helpful medication prevents this from ever happening. How must it feel for a mother to know that you cant go and buy your child medication because the government just shut down all stores for a day that may open the eyes to consumers? Anxiety that passes th rough mother knowing their child is at any time vulnerable to a life-taking illness. ​Of course, many feel differently. One argument cited by many others is that a National Buy Nothing Day would open the over spending ways of many Americans. Yes, maybe this all we need to open our eyes but would just like other events that were supposed to help us, more times than others we just go back to our old ways. Like for instance, in the time of The Great Dust Bowl, Farmers were  plowing heir fields non-stop and destroying the once fertile land. Then once the Dust Bowl came wiping out anything that was in its way, Farmers soon realized that their ways were in desperate need of reform, but what happened again? Farmers were back to their old ways and doing what they just did before. Its the mind of the American people that determine everything we do. Now should it be the governments job to show us our wrongs? Why no! We can say were going to change but do we ever really do? For a national objective to work, everyone has to consent to it. ​Although a National Buy Nothing would open the eyes of many consu mers everywhere, it can greatly impact others in different ways. Like the mother who cant find a way to feed her beautiful, small bundles of joy, or the teenager that cant buy his breakfast for the day, more negatives aspects come out of this than the good.

External Macro Environment Factors

External Macro Environment Factors Human Resource Management (HRM) according to Boxall and Purcell (2003:1) are the actions which involve the management of employment relationships in the firm. The modern world of business is changing rapidly in its attempt to gain and maintain a competitive edge. Business is operating in an environment affected by macro environmental factors ranging from Technology to Legislation and Globalization. These factors and many others are causing business to re-evaluate itself, both internally as well as externally. Structures are becoming flatter and decentralization is taking place as organizations attempt to remain competitive, survive and grow. The macro environment which is the main concern in this essay, are factors like political, economic, social, technological, environmental and legal environment (PESTLE) that can influence an organisation but are out of the organisations control. It is very important for HR practitioners to monitor the external macro environment since it can great ly make or unmake their businesses. This can be seen on the social changes technological advancement on workforce and HR policies in the last 10 years. In this essay, an elaborated definition of the external macro environment is well explained. Also, explanations of why it is necessary for HR practitioners to monitor the external macro environment , with reference to relevant academic theory is done. Also an illustration of how technological advancement and social change has affected the workforce and HR policies in the last 10 years is detailed out. The essay is then Concluded and bibliography cited as well. The marketing environment surrounds and impact activities carried out in the organisation. There are three key perspective on the marketing environment which involves the internal environment, the micro environment and the macro environment as shown on the diagram below. There are three key perspective on the business environment which involves the internal environment, the micro environment and the macro environment according to Kotler et al (2009). The micro environment influence the organisation directly and it includes the consumers, customers, suppliers, new entrants and competitors. All factors like men, money, machines, materials and market that are internal to the organisation are known as the internal environment. The external macro environment involves all those factors ranging from the political, economic, social, technological, environmental and legal environment also known as the (PESTLE factor) that affects the organisation uncontrollably, influences the organisations decisions and affects its performance and strategies. These macro factors are continually changing and the company has to be flexible enough to adapt to it. Looking at the political factors affecting a business, it involves factors like initiatives, grants and funding offered by the government, wars, government relationships with other countries, taxation policies, the goods and services the government produces, the health of the nation and the quality of the infrastructure of the economy such as the road and rail system. As such the degree of government intervention in the economy will affect companies operating in it. Thus the political atmosphere of a country should be checked before the establishment of a business. Economic factors includes interest rates, taxation changes, economic growth, inflation, loan access, unemployment, government spending consumer spending and exchange rates that affects the organisation. Using the economic factors to analyse a business scenario, a higher interest rates may deter investment because it costs more to borrow. Also, inflation may provoke higher wage demands from employees and raise costs. Also, a higher national income growth may boost demand for a firms products.   Social factors involves religious differences, ethics, lifestyle of the people, demographic changes, education and culture.  For example, changes in social trends can impact on the demand for a firms products and the availability and willingness of individuals to work. In the UK, for example, the population has been ageing. This has increased the costs for firms who are committed to pension payments for their employees because their staff are living longer. Technological factors involves the amount of research funding in the country, consumer purchasing power, technological advancement/ innovation, intellectual property and copy right infringement. For example Bar coding, online shopping, and new computer designs are all new technological development in the way companies do business due to the advancement in technology. Environmental factors involves a countries weather and climate change, the level of pollution, recycling considerations, legislative changes both current and future. Climatic changes can affect companies in the country. With the changes of global climates experienced today due to global warming, firms make this external factor a significant issue of considerations when expanding their businesses internationally Legal factors are factors like  safety, competition, health, future legislation, trading policies and regulatory bodies which relates to the legal environment in which firms operate. In recent years in the UK for example, there has been many significant legal changes that have affected firms behaviour like in areas like age discrimination and disability discrimination legislation and wages. HR practitioners have to carry out a PESTLE scan of the macro environment where the political, economic, social, technological, legal and environmental aspects of the business would be scanned properly. This is done in order to caution the HR practitioners on how changes in their external macro environment will impact the organisations activities. The external analysis of the macro environment has both micro and macro focus. At the level of the micro trend, HR practitioners should monitor suppliers, the strength of their competitors, labour supplies and the demographic population. At the level of the macro trend, HR practitioners should monitor the market forecast, technological trends, labour market forecast and trends in public sector employment and political atmosphere of the country. Also, the reason why HR practitioners scan the macro environment is to identify and analyse possible opportunities and threats of the industry as a whole that are outside the control of the industry using the opportunity and threat analysis (SWOT) analysis. The opportunities identifies the environmental characteristics that can help the organisation succeed and the threats identifies environmental characteristics that can prevents the organisation from being successful. As such, with the opportunity and threat analysis, HR practitioners are able to develop a corporate, business and functional level strategy. With the corporate level strategy, the organisation lays a plan action to manage the growth and development of the firm hence profit maximisation in the long run. With the business level strategy, the organisations find ways to counters its threats so as to compete effectively and with the functional level strategy, the HR practitioners establish a plan of action to improve its d epartments so as to create value. All these increases profits and the survival of the organisation. In addition, monitoring the external macro environment will assist the HR practitioner on how to recruit, retain, and develop the workforce they need. As such, HR practitioners are able to carry out their four main functions which are; the acquisition function, development function, motivation function and maintenance function. As such knowing the PESTLE environment will assist them to understand the policies, salaries, culture, educational levels of the potential employees in the country they operate. Once a sound external analysis is conducted, it can be reviewed and updated as part of the planning cycle to identify any significant changes in the environment. Also, looking at the social trends, HR practitioner monitor the external environment in order to know more about the culture of its employees. Trompenaars and Turner (1997) defines culture as the way in which a group of people live, solves problem and reconcile dilemmas. He also postulated seven dimension of culture that relates to relationships with people and their working environment. Also, Arnold et al cited in Handy (1986) pointing out that A strong culture makes a strong organisation and not all culture suits all purposes or people. As such it is necessary for HR practitioners to study their external environment so as to blend the organisations culture with that of its employees in order to create a good working atmosphere in the organisation. Thus resolving cultural differences will bring in team work and group cohesiveness. Furthermore, according to Devanna et al (1984), scanning the external environment assist HR practitioners to fit their HRM policies, practices and strategies in its competitive environment with the immediate business conditions that it faces as shown on the diagram below. The Matching model. As such, informations from the external environment assist HR practitioners to establish a proper mission and strategy, organisational structure and also enables human resource management policies to be used in their organisations based in different countries. The external environment has a major impact on the companies activities and decisions. More often than not, these forces are beyond the control of an organization and its managers. Though non-controllable, these forces require a response in order to keep positive actions with the targeted markets. Thus HR practitioners scan their external environment so that they can respond profitably to unmet needs and trends in the targeted markets. Linked to the above, accordingly, the factors of the environment will need to be considered as inputs in the planning and forecasting models developed by an organization.  Disturbances in the environment may spell profound threats or new opportunities thus the supervision helps HR practitioners to monitor and adapt to the environment if it is to survive and prosper. They thus identify, evaluate and react to the forces triggered by the external environment so as to make profits and survive in the long run. Furthermore, the knowledge gotten from the scanning of the external environment by HR practitioners assist them in gathering informations based on both government and private laws affecting the industry. Laws like rigid government laws in some countries that might affect their investments where by business may be doomed to be non starters due to business restrictions imposed by the government are determined before establishing a business. Also, cost of recruitment and standards in different from one country to another. More so, the availability of key inputs like trained managers, skilled labour, raw material are all impacted by the external environment. As such, monitoring the external environment enables HR practitioners to gather necessary informations which can affect their businesses. Until about twenty years ago, the world of work was an unfortunate place. Change of all kind was slow and non existence. Products had long life cycle, organisations were characterised by long control/ universally applied rule and technological innovations and inventions were pretty slow. In the last ten years technological advancement and social change has affected the workforce and HR policies. Looking at the way technological advancement has affected the workforce, in the past ten years, technological advancement has made globalisation possible amongst employees. Technological innovations in areas like learning and development, telecommunications, computers, satellite system have made it possible for information and innovation to rapidly cross national boundaries in between employees. More so, with technological advancement and the advent of new machines, there has been division of labour within employees hence creating higher quality products, just in time delivery and greater customization of products. In addition, Robinson (2006) pointed out that, within the past ten years in Britain for example, the amount of people employed in the manufacturing sector reduced by a half. Also there has been a decline in skilled and semi skilled manual jobs due to the rise in the creation of machines. The workforce nowadays is highly segmented and job length vary between the skilled and semi skilled jobs. Technological advancement has also affected HR policies in that Decades ago, HR management was autocratic in nature, employee made no decisions in the organisation. Organisational culture was hostile and employees didnt care about career advancement/ promotion opportunities since they were satisfied with their jobs. But in the past ten years, technological advancement has caused the establishment of new policies in order to work hand in hand with the growth. There has been a radical organisational restructuring programmes evidenced in de-layering, downsizing and decentralized. Also, with the advent of technology, HR practitioners keep restructuring new policies in terms of employing on a permanent basis and also offering career advancements in the form of training, development and promotion to employees as pointed out by Robinson (2006). Social change has affected workforce in that, in the past, men were employed most in organisation due to the increasing use of manual labour and physical power. But within the last ten years, there has been a steady increase in the participation of women in the labour force. Robinson (2006) analysed that there has been a rising level of divorce and single parents has lead to the provision of social welfare, health and educational services by HR practitioners. Social change has also affected HR policies in that, organisation in the past faced difficulties of dealing with cultural differences. Going international was very difficult due to the cultural barriers and differences. Within the past ten years, cultural policies have been instituted in order to deal with cultural conflicts in organisations. Organisations find it very easy to go international due to laid down policies, training and care giving to their expatriate employees. Also, HR policies have been adapted to satisfy consumers as customers have greater choice and power to influence purchase Boxall and Purcell (2003). As such, employees receive training in aspects like offering better customer care and services to consumers. All these has lead to increase profitability and survival of organisations. The external Macro environment also Known as the PESTLE environment consists of trends and forces which might not instantly influence the relations that a company has with its clients, suppliers and mediators, but afterward, macro-environmental changes will modify the nature of these relations. As explained above, it is very necessary for HR practitioners to monitor these macro external factors so as to foresee and manage any future impact it might have on the companies activities. Also, looking at the changes in technology and social change on workforce and HR policies in the past ten years, HR practitioners have adapted themselves to this changes by implementing new policies, strategies, rule and regulations to adapt their businesses to these uncontrollable factors.

The History of KKK Essay -- Ku Klux Klan American History Papers

The History of KKK Ku Klux Klan is a designation mainly given to two distinct secret societies that played a part in American history, although other less important groups have also used the name. The first Ku Klux Klan was an organization that thrived in the South during the Reconstruction period following the Civil War. The second was a nationwide organization that flourished after World War I. The original Klan - Six college students founded the Ku Klux Klan between December 1865 and the summer of 1866 in the town of Pulaski, Tennessee. Former Confederate officers, the six young men organized as a social club or fraternity and spent their time in horseplay of various types, including wearing disguises and galloping about town after dark. They were surprised to learn that their nightly appearances were causing fear, particularly among former slaves in the area. They quickly took advantage of this effect and the group began a rapid expansion. Various factions formed in different towns, which led to a meeting in April 1867 to codify rules and organizational structure. At this meeting, former Confederate General Nathan Bedford Forrest was elected Grand Wizard, or supreme leader, of all the Klan. The organization was divided into a number of realms, dominions, provinces and dens, which were in turn led by Grand Dragons, Titans, Giants and Cyclopes. Nathan Bedford Forrest The policies of Reconstruction (aiming to extend the rights of Southern blacks) had the unintended effect of pushing hundreds of resentful and anxious veterans into the Klan, which soon began instituting a systematic policy of violence in opposition... ...tion of everyone but themselves but they have put a lot towards making todays world a racist place. They have mentally disturbed peoples lives and terrorized villages by burning down their churches. Although the modern Ku Klux Klan, or KKK, is not the same group that terrorized African - Americans in the late 1800s and early 1900s, they still have the same basic goals and ideas. There are many local and regional KKK groups such as the Oregon Knights of the Ku Klux Klan and the New Order Knights of the Ku Klux Klan. The Knights of the Ku Klux Klan is the national and largest organization, but the only one seeking a political agenda. They are the group that claims they are keeping alive the spirit and ideas of the original Klansmen but there are only a few thousand left as we think but it’s a very secret society.

Engineering Drawing Short Questions

Define engineering drawing. Why drawing is called universal language of engineers? Ans1:-A drawing drawn by an engineer having engineering knowledge for the drawing purposes is an engineering drawing. It is meant for communicating his ideas, thoughts and designs to others. Engineering drawing is a starting point of all engineering branches such as Mechanical, Production, Civil, Electrical, Electronics, Computer science, Chemical etc. It is spoken, read, and written in its own way.Engineering drawing has its own grammar in the theory of projections, its idioms in conventional practices, its punctuations in the types of lines, its abbreviations, symbols and its descriptions in the constructions. Q2 – Name different types of drawing instruments. Ans2 – Drawing board, T-square, Set Square, Scales, Pencil and sand paper block, Drawing pins or cello-tape, Duster or handkerchief, eraser etc. Q3 – Why pencil is rotated in finger while drawing a long line? Ans3 – T he pencil is rotated in finger while drawing a long line in order to get a line of uniform thickness throughout.Q4 – How will you test the set square and T-square? Ans4 – Testing of T-square – (i) Check all screw heads and tighten, if necessary (ii) In order to check the T-square, first of all draw a horizontal line. Now reverse the T-square and again draw a horizontal line with working edge. If both the lines coincide with each other, then the working edge of Tsquare is alright. If there is a difference in two lines, then working edge is not correct and the line gives twice the error of the working edge. This error should be rectified by scraping the edge with a scraper or a sharp knife.Testing of set-squares – The straightness of edges of the set-square can be checked by drawing a vertical line. Then reverse the set-square and draw again vertical line. If there is any difference between the two vertical lines then working edge is not correct and the lin e gives twice the error. This error can be removed by straightening the edges by means of a scraper or sand paper. Q5 – What are the standard sizes of drawing sheets according to I. S. I. and which is suitable for drawing work? Ans5 – The standard size of sheets according to I. S. I. are A0(1189 X 841), A1 841 X 594), A2(594 X 420), A3(420 X 297), A4(297 X 210) and A5(210 X 148). Drawing sheet of size 594 X 420 i. e. A2 size is generally used by engineering students as it is very handy and easy for drawing work in class. Q6 – What are the ways of sharpening a pencil for good and accurate work and which type of pencil is more suitable for drawing work? Ans6 – There are two ways of sharpening a pencil (i) a small piece of sand paper of zero grade, pasted upon a piece of wood. (ii) Sharpeners. Usually hard pencils such as H, 2H etc are used for making the engineering drawing.Q7 – Why cello-tape is used instead of drawing pins, now a day? Ans7 – Now a days, cello tapes are used in place of drawing pins for its practical convenience as the drafter, Tsquare and set-squares can be moved easily over the tape. Q8 – What is layout of drawing sheet? Ans8 – The selection of suitable scale and allotment of proper space for margin, title block, parts list, revision panel, folding marks etc. on the drawing sheet is known as layout of drawing sheet. Q9 – Why is the layout of sheet is necessary? Ans9 – Layout of the drawing on the drawing sheet is necessary in order to make its reading easy and speedy.The title blocks, parts list etc will provide all the required information. Q10 – List out the contents of title block and material list Ans10 – The title block should contain at least the following informations. (i) Name of the institution (ii) Name of title of drawing (iii) Name, Class and Roll no. of the student (iv) Scale (v) Drawing number (vi) Symbols denoting the method of projection Q11 â €“ What is the necessity of folding a drawing print? Ans11 – Folding marks are made on the sheet to facilitate folding of prints for the purposes of filing and binding in the proper and easy manner.Q12 – What do you mean by convention or code? Ans12 – The representation of any matter by some sign or mark on the drawing is known as convention or code. The conventions make the drawing simple and easy to draw. Q13 – What do you understand by thickness of lines? Ans13 – There are three distinct thickness of lines used in engineering drawing. These lines are specified as thick, medium and thin lines. The line specified as thick is usually 3 times thicker and the line specified as medium is 2 times thicker than a thin line. Q14 – Where and why a cutting plane is drawn in a drawing?Ans14 – The section plane are generally perpendicular planes. The projection of a section plane, to which it is perpendicular, is a straight line. This line w ill be parallel, perpendicular or inclined to the x-y line. The cutting plane is drawn in a drawing to show the inner details of an object. Q15 – What is the necessity of convention breaks and convention of materials? Ans15 – Long members of uniform cross-section such as rods, shafts, pipes etc. are generally shown in the middle by the conventional breaks so as to accommodate their view of whole length on the drawing sheet without reducing the scale.The exact length of the member is shown by the dimension. Q16 – Why the conventional representation of common features are adopted on the drawing? Ans16 – The conventional representation of common features are adopted on the drawing to save the unnecessary time or space on the drawing. Q17 – What are the main requirements of lettering? Ans17:- 1) The knowledge of shape and proportion of each letter. 2) The knowledge of the order and direction of the strokes used in making letters. 3) The knowledge of th e general composition of letters. 4) The knowledge of rules for combining letters into words and words into sentences.Q18 – What is lettering? Ans18 – The art of writing the alphabets A, B, C,†¦Ã¢â‚¬ ¦. Z and numbers such as 1, 2, 3†¦Ã¢â‚¬ ¦0 etc. is known as lettering. Q19 – What do you mean by composition of letters? Ans19 – The composition means the composing of letters into words and words into sentences. The letters are so arranged that the open area between two letters of a word appears equal to the eye judgement. Q20 – What do you mean by uniformity of letters? Ans20 – The uniformity of lettering means keeping the height, inclination, spacing and strength of letters to be same. It is very essential for good lettering in engineering drawing.Q21 – What do you mean by normal, compressed and extended lettering? Ans21 – Normal lettering: – The normal lettering have normal height and width and are used for gen eral purposes. The width of the normal letter is about 0. 67 times of the height of the letter. Compressed lettering: – The compressed lettering are those which are written in the narrow space. These are used when the space is limited. The widths of the condensed letters are less than height. Extended lettering: – The extended lettering are those which are wider than noramal letters but of the same height.Q22 – What are the guidelines and why they are necessary in lettering? Ans22:- The lines which are used to regulate the height and inclination to the letters and numerals are known as guidelines. These are to be drawn at random. The guidelines are used to regulate the uniformity of the letters. Q23 – What do you mean by single stroke letters? Ans 23:- Single stroke letters means that the thickness of the line of the letter should be such as is obtained in one stroke of the pencil. Single stroke letters are of two types. 1) Vertical 2) Inclined (75deg. Wi th horizontal) Q24 – What is the gothic and roman lettering?Ans24 – Gothic lettering – The lettering in which all the alphabets are of uniform width or thickness is known as gothic lettering. It can be divided into following groups. (i) Vertical or Upright vertical gothic lettering (ii) Inclined or Italic gothic lettering Roman lettering – The lettering in which all the alphabets are composed of thick and thin elements is known as roman lettering and can either be vertical or inclined. Q25 – What do you mean by freehand lettering? Ans25 – The art of writing the alphabets without the use of drawing instrument is called freehand lettering. The freehand lettering is of the following types. a) Vertical or upright freehand gothic lettering. (i) Single stroke vertical freehand gothic lettering. (ii) Lowercase vertical freehand gothic lettering. (b) Inclined or italic freehand gothic lettering. (iii) Single stroke italic freehand gothic lettering. (iv) Lower case italic freehand gothic lettering. Q26 – What should be the grade of pencil used for lettering? Ans26 – HB and H grade pencils sharpened to a conical point should be used for lettering. To keep the stroke of the letters uniform, the pencils should be rotated between the thumb and fingers while lettering. Hard pencils such as 2H or 3H should be used to draw guidelines.Q27 – What is the importance of dimensioning? Ans27:-1) Dimensioning expresses all the sizes and other information necessary to define the object. 2) It must be done with due regard to manufacturing processes and inspection requirements. 3) The dimensioning also includes expression of tolerances necessary for the correct functioning of the part given to be assembled. Q28 – What is dimensioning? Ans28 – The art of writing the various sizes or measurements on the finished drawing of an object is known as dimensioning. Q29 – What do you understand by the term notatio n of dimensioning? Ans29 –The notation of dimensioning consists of dimension lines, extension lines, arrow heads, dimension figures, notes, symbols etc. Q30 – What is a leader or pointer line? How a leader should be drawn? Ans30 – A leader is a thin continuous line drawn from note of the figure to show where it applies. It is terminated by an arrow head or a dot. The arrow head touches the outline, whereas the dot is placed within the outline of the object. The leader is generally drawn at any convenient angle, usually 30? , 45? , and 60? but not less than 30?. Q31 – Explain with the help of a simple sketch (i) size dimensions (ii) location dimensions.Ans31 – Size dimension – The dimensions which indicate the various sizes of the object such as length, breadth, diameter etc. are known as size dimensions. These dimensions are represented by letter ‘S’. Figure. Location dimension – The dimensions which locate the position o f one feature w. r. t. the other feature are known as location dimensions. Distances between the centre lines of the holes from the edges are given by location dimensions. These dimensions are marked by letter ‘L’. Figure. Q32 – What are the aligned system and unidirectional system of dimensioning? OrWhat are the different methods of dimensioning? Ans32:-1) Aligned Method: – In aligned system, the dimensions shall be placed parallel to and above the dimension lines, preferably in the middle and not by interrupting the dimension lines. Here the dimensions can be read from the bottom or from the right side of the drawing. Figure. 2) Unidirectional Method: – In this system dimensions shall be horizontally placed so that they can be read from the bottom of the drawing sheet.

scary movie essays

scary movie essays  ¡Ã‚ °Mom, there ¡Ã‚ ¯s a spider on my bag, ¡ cried seven-year old Jimmy.  ¡Ã‚ °Just stomp on it, honey, ¡ Jimmy ¡Ã‚ ¯s mom, Sandra replied. Following his mother ¡Ã‚ ¯s instructions, Jimmy scanned his eyes over his bag, found the spider, raised his right foot, and stomped hard onto the newly waxed tile floor. Afterwards, Jimmy called out to his mother and said,  ¡Ã‚ °Mom, I killed the spider. ¡  ¡Ã‚ °Well was that hard, Jimmy, ¡ Sandra called back from the kitchen.  ¡Ã‚ °I guess not, ¡ Jimmy doubtfully replied. Unknown to Sandra and Jimmy, himself, this led to a 360  ª change in him. From thereon, the once timid and shy Jimmy warped into a distorted and abusive urchin. He stomped on everything his eye was able to find: spiders, ants, bugs, or frankly anything that was smaller than him. Moreover, he was watching movies such as the  ¡Ã‚ °House of the Dead ¡ and he used his stuffed animals as mannequins to imitate the slaying scenes in the movie. Jimmy ¡Ã‚ ¯s recent behavior made Sandra disturbingly  ¡Ã‚ °sick. ¡ Being a toddler, Jimmy had always played and chased the chickens around in the barn. However this has now turned into a horrendous act of rage. He began to behead chickens with an ax that he found in the mother ¡Ã‚ ¯s toolbox. On afternoon, all the chickens in the farm met their fate as dozens of heads lay in their pool of blood. Making a routine visit to the barn to feed the chickens, Sandra was petrified at the sight of the blood-curdling scene. Immediately thinking that this was the act of Jimmy, Sandra demanded to see Jimmy at once. Yelling frantically, he did not answer to her calls. The furious Sandra marched into the house and called out for Jimmy.  ¡Ã‚ °Mommy, I ¡Ã‚ ¯m here, ¡ Jimmy replied. Turning to the direction of the voice, Sandra was scared stiff.

Free Essays on Eragon

Eragon The author Christopher Paolini wrote Eragon at the age of 15. The story takes place in a huge kingdom called Alagaà «sia where the evil Dragon Rider emperor, Galbatorix, rules with his black dragon, Shruikan, and the Thirteen Forsworn Riders that followed Galbatorix. In this kingdom, a boy by the name of Eragon lives in the small village of Carvahall. Eragon is fifteen years old and has dark hair, brown eyes, and a little fit. While Eragon was out hunting for deer in the Spin, an untamed mountain range, he found an oval shaped, dark blue stone with veins of white that spider webbed across it. He remembered how the old stories told to treat magic, and those that use it, with caution. After a while of thinking it over, he decided to keep the stone just in case it was worth some money. When he finally got home, he wrapped it up and stuck it on the shelf in his room. The next day, a traveling caravan came to town. The caravan came once a year and brought items to sell from all over the kingdom, and to buy items from the villagers. Eragon’s most trusted friend Brom, the village’s storyteller, took him to a man that could tell Eragon how much his stone was worth. The jeweler was amazed by the stone but was unable to tell exactly how much it was worth. That night, Eragon awoke to a startling rattle. He looked around his room to make sure no one, or nothing, was there. Just then, the stone rolled off the shelf onto the floor. Eragon watched the stone from his bed as the stone started shaking and made strange noises. He walked over to the stone and noticed that it was starting to crack open, and out of the opening hole popped a lizard looking head. As the creature came more out of the stone, he realized it was really a dragon’s egg he had found. He named the dragon Saphira and made a house for her in the forest behind his home. One day, three dark strangers, the Ra’zac, appeared in the village asking if anyone kne...

How Juno Beach Invasion Impacted the World and Canada Essay

How Juno Beach Invasion Impacted the World and Canada - Essay Example The battle did not only define the destiny of Canada but also had a huge influence on the world. The name D-Day means the day that military bombardments began in earnest, which included heavy landings on Normandy beaches. This battle acted as a defining moment in the history of Canada, where they showed a lot of resilience and bravery1. I have chosen to write about the Juno beach invasion first of all because my father is a veteran soldier who personally participated in it and secondly out of my interest in the events of the battle. My father was among those who fought the war to ensure that Canada emerged victorious. At the time of the invasion, my father was in the Royal Canadian Core of Signals (RCCS), at the third Canadian Infantry Division. His contribution to the success of the Canadian troops in fighting off German troops was quite significant. More particularly, he managed to go in on the third wave as a radio operator and set up communication lines that made communication be tween the Canadian troops effective and efficient. In addition, he was among the soldiers who drove the German troops out of Caen. My interest in the D-Day is particularly motivated by the fact that the battle that took place on the day is a major event which not only impacted on Canada but also shook the world. An overview of the D-Day Invasion Collaboration According to Copp, â€Å"the Allied Campaign in Normandy resulted in one great military victories in modern history†2. The events that took place during the battle demonstrate the extent to which collaboration is important in winning a battle of that involves several players. This is because the war was not won by a single country. Rather, it was won collaboratively by the Allied forces which mainly comprised the U.S., British and the Canadian forces3. The war began shortly after 5 a.m. on June 6, 1944, commonly referred to as the D-Day because of its significance to Canadians. The battle was fought between the Allied fo rces and Nazi Germans4. Since the battle had to be fought from different angles and directions, the Allied forces’ strategists assigned the Canadian troops a key role to play on the eventful day. They were â€Å"to take one of the five designated beaches where Allied forces were to land to begin the liberation of Europe from Nazi Germany†5. They were assigned the responsibility of taking charge of Juno Beach6. The U.S. troops, on the other hand, were to take up Omaha and Utah beaches located on the west even as the British troops took charge of Gold and Sword beaches. Out of their collaboration, the Allied forces won the victory, defeating the common enemy and emerged as a dominant force to reckon with in Europe and the world at large. Conflict The D-Day conflict revolved around the need to liberate Europe from Nazi Germans7. The conflict was catalyzed by increased oppression of people in Europe by the Nazi Germans. Members of the Allied camp felt that they needed to s tep in and restore peace in Europe. Unfortunately, attempts by the U.S., Canada, and Britain to liberate Europe peacefully failed. The Nazi Germans refused to cede ground peacefully prompting the Allied camp to use force. In just a day of the deadly fighting, the Allied forces emerged victorious against their German counterparts8. The most lethal seaborne invasion was aimed at sandy beaches found along the Normandy coast, east of the jutting Cotentin Peninsula and west of the Seine River.

Factsheet drybulk Essay Example | Topics and Well Written Essays - 500 words

Factsheet drybulk - Essay Example There will be huge demand and supply for the dry bulk as long as the buyer ships the products and commodities from one place to the other. However, due to increase in the price of the commodities, the present market position stands at a lower level. The main reasons are lower market expectations, lower demand for the cargo supply, critical conditions of market life cycle and declining fleet growth. The company needs to control its existing strengths in shipping and attempt to expand its markets to the major areas such as South Asia and North America, to gain a wider area of operation. Dry bulk market may have higher rates in the future. Temporary rise in rates also seems possible during the year. While world trade is likely to increase at a reasonable rate in 2012 as well as 2013, the amount of new capacity will consume high rates towards operating expenses. â€Å"Emerging markets such as India and China are likely to be key to the success of Farstad. As they are the growth markets for any new company, so further addition to the company’s top line would be dependent on its efforts to exploit the trade routes emanating from these countries† (Abhishek, n.d.). â€Å"Capesize, Panamax, Handymax and Handy size† (Segments, 2012).

Common law and equity Essay Example | Topics and Well Written Essays - 1000 words

Common law and equity - Essay Example Equity was developed in order to overcome the inadequacies of common law. Equitable remedies are available in a number of areas where common law is either incapable of providing justice or is not faultless in providing justice to the individuals. The main purpose of equity jurisdiction is to support the existing laws. Equity was developed to propose principles that are either ignored by common law or not formally accepted in that set of law. Moreover, equity proposes certain remedies that are unavailable in common law. In certain circumstance, common law decisions or remedies are insufficient to provide justice to the innocent (Hudson, 2009). For instance, in the matters involving mortgages, where the lenders are to a piece of land as a security of the loan granted, the principles in equity and common law greatly distinguish from each other. Let’s assume that Angelina grants a loan of $5,000 to Joseph, after considering a piece of land as a security that worth $8,000. Accordin g to the contract, the land in question would be legally transferred on the name of the lender (Angelina), on the terms that she would retransfer the land on Josephs name if he repays the loan in the specified time. If Joseph fails to repay the loan in the specified time, common law gives no entitlement to Joseph for the land that was conveyed and the duty to repay the loan still exists. However, equity practices such situations in a different and more reasonable manner. According to the rules of equity, Joseph would be given another chance to repay the loan in a new specified time. If Joseph still fails to repay, the land which was let for security will be sold and the loan will be repaid. The additional amount would be given to Joseph as it belongs to him. It is not just the matters of mortgages where equity provides a more reasonable and just decision but it also works better in many other areas. Equity and common law are not only different in terms of laws and

Patents and Copyrights - Essay Example In such a society, innovation would be stifled. In the scenario mentioned above, if Google obtained a patent for their new software, they may have market power and that may enable them to charge high prices for the software. However, Google may not charge whatever they want even though market power gives them the ability to set the prices. The seller will set the price in relation to the demand curve because if the price is set too high, a downward-sloping demand curve is imminent, hence a decrease in demand (Richard , 2012). In conclusion, the existence of a patent prevents others from producing and selling the patented product. It is on these grounds that a patent is considered a monopoly privilege granted by the government. Additionally, the monopoly grant has a prima facie impact on trade, because the monopoly conferred by the patent is the right to exclude others from manufacturing or selling the patented product. On the other hand, copyright is not a right to the exclusive use of a fact, an idea, or a combination, which by the natural law of property all are free to use; but only to the labor expended in the thing itself (Journal of Libertarian Studies,

C & C Grocery Stores Case Analysis Article Example | Topics and Well Written Essays - 250 words

C & C Grocery Stores Case Analysis - Article Example Recent structure of C&C also fails to change its environment, i.e. stores that are in sub urban areas are similar to those that are present in low income areas. New systems for supply and chain management were not yet implemented in stores. The friendly and informal environment that is created by the Doug Cummins in C&C was disregarded and therefore the within stores the cooperation get worsened. For instance an issue takes place in Louisiana store between store manager and grocery merchandiser when they decide to improve Diet Coke and Coke as a featured article of merchandise sold at a loss in order to draw customers. But the cooperation among these was poor and result in lack of preparation and communication led to their unwilling to cooperate regarding where the Coke can be displayed by the store manager. These issues could be resolved by powering the store manager in order to coordinate effectively in the stores. By doing this the cooperation would increase as the store manager got the authority and power to change whatever he or she requires for the sales improvement. This power would also increase the satisfaction of the store manager and they run their store in a profitable manner, and also can get training they require for their promotion as well as improvement of store. From my perspective I believe the new structure as much effective. This structure allows distinct responsibility areas and management. However, in the previous structure the name of responsible person was hard to determine, because whenever the store fails and the store manager is blamed he only talk about the way he desire to do something but can’t do the same way he wants because of meat/produce reject that by saying that it was not for their benefit. This issue is one of the core issues of the old structure, and it is entirely eliminated in the recent

In this sonnet Bill Collins seems to criticize the sonnet form of Shakespeare. Also, in the sonnet of Bill Collins he puts many allusions in his sonnets. For example, in the beginning of the sonnet where he mentions in an alliteration form in line 3 where you get the allusion of the story troy; to launch a little ship on loves storm-tossed seas. The next allusion when he mentions A famous sonnet writer named Petrarch in line 12, as well as the final last allusion motioned towards the end of the sonnet in line 13, where he mentions shake spears act called Twelfth night.

Debates On Mercy Killings

Debates On Mercy Killings If a Wife kills her Husband because of the pain he is in from his medical problems. Do you think that she should be charged with manslaughter, homicide, or any other charge acquitted to death of another human being? I say she should. Should euthanasia be legalized in our country? This is indeed a question often discussed in community. In some countries like Holland, its already allowed, while the German politicians cant stop discussing about it over and over again. Both states could argue with several statements and their opinions about it, but which of them would be correct? Is there even a right decision? First of all, euthanasia, also called mercy killing, is the act of putting a person or animal to death painlessly or allowing it to die, as by withholding extreme medical measures, when its suffering from an incurable, especially a painful, disease or condition. In other words, if a person is death-ill or otherwise has lost his will to live, doctors are allowed to end the patients life if theyre requested/allowed so by the person. Should the patient be unable to make the decision himself, his/her family has to decide if they want to continue with medical treatment or not. If an animal is suffering from an incurable disease or condition, the owner has to decide about its fate. There are several forms of euthanasia: Voluntary euthanasia is the form of euthanasia conducted with the patients permission. Involuntary euthanasia is conducted without the explicit consent of the individual concerned and means that an individual makes a decision for another person incapable of doing so. Both voluntary and involuntary euthanasia can be conducted passively or actively. Passive euthanasia entails the withholding of common treatments, such as antibiotics, necessary for the continuance of life. The administration of increasingly necessary, although toxic doses of Opioid is regarded as a passive measure. Active euthanasia on the other hand is the conducting of life-limiting measures on the basis of the actual or presumed wish of a person and is also called assisted suicide. Except for the Netherlands, Belgium and Luxembourg, it is prohibited worldwide. Although euthanasia may not be a common and appreciated topic for daily-life, one can still find a lot of reasonings for and against it after a little research. One of the most popular arguments to forbid (active) euthanasia is the question how it can be decided whether a patient is beyond any hope to heal or not. Even if the possibility of recovering is only up to a minimum, some people would refuse to end their loved-ones life before time and rather waited for time and medicines to take care of the injury/disease if theyre not entirely sure that theres no change of betterment. And most important, what if the concerned person is no longer able to decide for himself? Who would be able to take the burden of ending a family members life? The guilt of having done something like that would surely shatter everyones mind, so its far easier to just wait and watch things develop. Not to mention that it would be a violation of the Bibles laws. As it is clearly written in the Ten Commandments, Exodus 20: 2-17, the sixth commandment says: You shall not murder. And isnt murder defined as killing of another human being with intent ? So what is euthanasia but murder? Adding to that, it can also be said that there had been cases in Holland where doctors conducted both passive and active euthanasia at their patients without permission. And that cannot be allowed in our state. But of course, there wouldnt be a contra without a pro. In fact, all of the listed arguments above not to legalize euthanasia can be negated. As a first addition, euthanasia is only conducted in really incurable cases, not after a simple car-accident where one has broken his leg and believes to suffer greatly, but more in cases where the patient can only be kept alive with great medical treatment, maybe even attached to a machine, having lost all power or abilities to take care of himself. If one is not aware of how much pain this inflicts on both the body and the mind of the concerned person, he can hardly understand how much of a release it would be for them to be allowed to let go. Especially old or handicapped people feel like a burden for their family. As long as one is able to decide for himself, he has the right to determine what shall happen with him, this also including the right to end his life. And it would at least happen under medical observation, painlessly, which is really good. Just imagine, for example, your paralyzed uncle would want to end his life, but was not allowed to assign for it in a hospital, ending up directing his wheel-chair to the nearest stairs in his desperation at full speed. No, nobody wants this to happen, do they? Then let them finally fall asleep and dont disturb them. Death belongs to the flow of life just as well as life itself, it cant be stopped, no matter how much we sometimes crave for it to change. I know, its hardly believable, but releasing a concerned family member is also a relief for the rest of the family. Of course there will be a lot of sorrow, but they will soon notice that is had been entirely to his best. Another aspect is that you cant let someone else suffer through great pain just because of your morals and your religion. Really, atheists wont care a bit if it was against your gods word to kill another person, because, stuck in unbearable pain, it simply doesnt matter to them. Every person has his own definition of right and wrong, so forcing someone else to follow your completely different ways would be the real crime. As for the abuse of legalized mercy-killing in the Netherlandsà ¢Ã¢â€š ¬Ã‚ ¦ Well, sadly but true, thats how our world functions. There will always be abuses of any kinds of rules, and there will never be a time when mankind decides to stop eating itself away. Were like that. I dont like it either, but we cant just ignore it. Finally, I would like to clarify that I neither fully favor nor forbid euthanasia because I can very well understand both sides of the argumentation. My personal opinion is that everyone should talk to their loved-ones to plan out what should happen in case of such an emergency, so that it will later be clear whether the person wants to live on or not.

Aluminum :: Research Essays

Aluminum Aluminum is the second most abundant element in the Earth’s crust. It has a concentration of about 8.2 percent (Craig et al 264). Aluminum â€Å"is malleable, ductile, and easily machined and cast; and has excellent corrosion resistance and durability† (http://minerals.usgs.gov/). It is evident in everyday life. Aluminum is a very useful abundant metal. A large fraction of the mineral products we seek are metals, such as aluminum (Halleck, 1/20). The major uses of aluminum are transportation, packaging and containers, and building products. Some other uses are electrical and consumer durable goods (Craig et al 266). It is important in the use of transportation because it is lightweight, which enables more efficient use of fuels, and it is resistant to corrosion (Craig et al 266). â€Å"Commercially pure aluminum is comparatively soft and ductile†¦it has tensile strength of 13,000 pounds per square inch† when it is in its annealed condition (Hobbs 76). When the metal is strain hardened, its tensile strength is 24,000 pounds per square inch (Hobbs 76). The tensile strength can increase even more when other elements are added to the metal to form alloys. Some of these elements used for alloying are copper, iron, silicon, magnesium, nickel, and zinc (Hobbs 79). Aluminum is also common in minerals such as feldspar, mica, which are silicates, and clay. Most of aluminum production has been from bauxite. â€Å"Bauxite can form from the weathering of any rock that is aluminum bearing† (Craig et al 267). Most bauxite mining is done in tropical regions where there is not an abundant amount of cheap electricity or large markets for the aluminum production (Craig et al 268). The bauxite is crushed, washed, dried, and then shipped to processing sites. Aluminum is produced by the â€Å"electrolytic reduction of alumina in a molten bath of natural or synthetic cryolite† (Craig et al 268). This process is very energy intensive so it is done in areas where electricity is cheap. â€Å"Aluminum recovery from scrap (recycling) has become an important component of the aluminum industry† (http://minerals.usgs.gov/). About thirty percent of aluminum is recycled each year. Sixty percent of that is from new scrap and forty percent is from old scrap (http://minerals.usgs.gov/). Some examples of recyclable aluminum are automobiles, windows and doors, appliances, and cans. Aluminum is also used in many cooking utensils, electrical conductors, buildings, and in transportation industries.
