The Constraints on Adolescent Learning Essay - 3088 Words

Personalities, social skills and intellectual development are only some of the key factors that effect how pupils learn and achieve differently to one another. Every child responds individually to their specific needs and environment, and the extent of that achievement can be often be linked with external factors as pupils are naturally influenced by a variety of different constraints. These factors that are not concrete and will change and alter throughout an adolescent’s development, as Piaget (Piaget 1970) believed the mind changes and works in different ways at different stages so do the conditions that enhance and limit progress. Furthermore these constraints can have both a beneficial and a detrimental effect on the learning†¦show more content†¦Additionally a lack of income might mean that children from deprived families loose out on educational visits, access to the internet and books, limiting educational opportunities and resources that could be used to exte nd a pupils schooling. A constraint that could directly affect an adolescents learning in Art and art related subjects as equipment and resources are limited and must often be supplemented by the pupils to aid in the production of high quality outcomes, therefore penalising those who cannot afford the best materials. Physiologists Vygotsky and Piaget’s ideas can both been seen to effect the nature of education and the environment in which children learn due to the theories they devised throughout the twentieth century and whilst their concepts may appear to be different I believe that they do hold some similar threads. Vygotsky believed that children develop through interaction with people, communities, their peers and essentially the environment around them, yet Piaget theorised that pupils learnt through constructing their own knowledge and that the brain changes from using concrete to formal operations during puberty (Piaget 1970 cited in Schwebel 1974). However, for a child to construct new ideas and expand upon their knowledge are they not first influenced by what they see around them and then react to what isShow MoreRelatedEssay on Age and Second Language Acquisition1486 Words   |  6 Pagesneeds to happen early on life, is there an ideal age to learn a second language (L2)?

The Regression Model Of The United States - 1762 Words

First of all, I would like to mention that it is more reasonable to compare the models that are based on the same data, so I tried to use the same variables and the same missing value treatment approach (excluding decision tree) to all of the models. All the 3 models showed a performance of nearly the same quality, according to the various lift charts produced and presented in the further parts of the report. However, the difference becomes more evident on the % captured response and the most efficient and useful model turns out to be the logistic regression model. It is described in a greater detail in part 4 of this report. This ROC plot indicates that the logistic regression is also efficient in terms of trade-off between†¦show more content†¦2. Recommended Model - Decision Tree The recommended decision tree model includes 2 variables : annual income and loans, both of them are interval variables and represent the original observations. They were chosen for the final model, because after several trials, they proved to be the key ones in determining the rules within decision trees. In terms of missing values, nothing particular had to be done, because decision trees conveniently handle missing values by default. As for the splitting criterion, after getting more knowledge about each of the criteria and performing numerous trials , Gini was chosen, due to its ability to measure the differences between the values of a frequency distribution. Presented below is the model assessment graph that represents the misclassification rates at each number of leaves. As can be seen from the graph, the model enables to reduce the difference between the training and actual sets compared to other situations when different settings were used and different variables included. Another indicator of this model’s usefulness is the lift value graph. The base line represents the nonexistence of our prediction model, while the intercept of the red line states that with this decision tree we can identify 3,7% more bad customers than we would have done without it.

It covers the complete lifecycle of the pages on your site, from providing simple tools to create the content, through to publishing, and finally to archiving. It also provides the ability to manage the structure of the site, the appearance of the published pages, and the navigation provided to the users. The functionality of a content management system can be broken down into several main categories: * content creation * content management * Publishing * presentation Content Creation At the front of a content management system is an easy-to-use authoring environment, designed to work like Word. This provides a non-technical way of creating new pages or updating content, without having to know any HTML. The CMS also allows you to manage the structure of the site. That is, where the pages go, and how they are linked together. Many even offer simple drag-and-drop restructuring of the site, without breaking any links. Almost all content management systems now provide a web-based authoring environment, which further simplifies implementation, and allows content updating to be done remotely. Content Management Once a page has been created, it is saved into a central repository in the CMS. This stores all the content of the site, along with the other supporting details. This central repository allows a range of useful features to be provided by the CMS: Keeping track of all the versions of a page, and who changed what and when. Ensuring that each user can only change the section of the site they are responsible for. Integration with existing information sources and IT systems. Publishing Once the final content is in the repository, it can then be published out to either the website or intranet. Content management systems boast powerful publishing engines which allow the appearance and page layout of the site to be applied automatically during publishing. It may also allow the same content to be published to multiple sites. Of course, every site looks different, so the CMS lets the graphic designers and web developers specify the appearance that is applied by the system. These publishing capabilities ensure that the pages are consistent across the entire site, and enable a very high standard of appearance. This also allows the authors to concentrate on writing the content, by leaving the look of the site entirely to the CMS. Presentation The content management system can also provide a number of features to enhance the quality and effectiveness of the site itself. As an example, the CMS will build the site navigation for you, by reading the structure straight out of the content repository. It also makes it easy to support multiple browsers, or users with accessibility issues. The CMS can be used to make your site dynamic and interactive, thereby enhancing the site’s impact. * Examples – WordPress, Joomla, Drupal Videos to Watch * http://www. youtube. com/watch? feature=player_detailpagev=VdvEdMMtNMY * http://www. youtube. com/watch? feature=player_detailpagev=jexUS43sdeQ * http://www. youtube. com/watch? feature=player_detailpagev=VdvEdMMtNMY * http://www. outube. com/watch? feature=player_detailpagev=RUSAJ_2ZqNI * Database-driven software that creates pages when needed and tailor-makes them for the time, the circumstances, the user * The CMS fetches content (e. g. text, data, pictures) from the database and creates a webpage with pre-defined formatting chosen by the webmaster. * The same pages might look different for each perso n viewing it (e. g. their ‘My eBay’ pages, or their Facebook pages. ) Pros and Cons Pros * Site maintenance is far easier and quicker * Sites become dynamic and pages change automatically Easier to manage assets (pictures etc) * Better looking sites * Site has a consistent appearance across all pages * Far less chance of 404 errors or bad links Cons * Must install CMS software onto your webserver – some are expensive * Must learn how to use the CMS * Can be expensive/slow to convert an existing static site to CMS Software Webmaster creates content (e. g. body text) Media (pix, videos etc) are stored in the database The CMS combines content, media, formatting to create web pages which are sent to the visitor’s browser Cascading Styled Sheets (CSS) CSS * Instead of repetitively formatting lots of types of text in the same way, define the formatting in a CSS file and just mark text with the style it needs * To change the look of main headings, change the defi nition of HEADING1 once in the CSS file. * Don’t have to find and change every piece of HEADING1 text across the site * Far quicker, easier * Creates consistently formatted sites * E. g. CSS file contains â€Å"Heading 1 = Bold, TNR, size 20† * In a webpage, some text is tagged as being â€Å"Heading 1† style.

A comparison of poetry about life Essay Example For Students

A comparison of poetry about life Essay Dover Beach and Light Shinning out Of Darkness were written in 1769 and 1851. Dover beach was written by Matthew Arnold and light Shinning out Of Darkness by William Cowper. These poems are similar because they are both poems about religion. With Cowper, he writes and hymn/song which makes it more enjoying to read. Light shinning out of darkness is about how God is mysterious, his purpose will ripen fast these show that even tho we dont see go, whatever choices he makes they will always be for good and we will see them clearly. Gods wants us to have courage and if we do we will be rewarded for it, God wants us to trust in his grace and do not think he is mean but to see his kindness as Cowper describes as behind a frowning provenance hides a smiling face. Cowper thinks that if you do not believe in God then you are blind and he describes as blind unbelievers sure to err. Whereas, just over 80 years later a poet named Matthew Arnold wrote Dover beach. As he wrote it in the Victorian period, more people gradually changed their religious views from Christians. In the first verse he tells us about where he is on the French coast the light gleams, he is in a beautiful place yet he writes a sad poem on his honeymoon. He then goes on to say when he hears the waves come in and out it reminds him of human misery. In stanza 3 he explains about the sea of faith about how it was once too, at the full and round earth shore, he thinks that everyone has lost faith as it used to be full and everyone believed I God now it is retreating because now more people believe in science. In addition he finally writes about how he thinks the earth is a beautiful dream and the only thing that we dont have is all the joy, love light, certitude, peace, pain which people have no idea why they do not have as he writes ignorant armys clash at night which ruin the beautiful earth th at Arnold sees. Light shining out of darkness and Dover beach similar poems by two very different poets. William Cowper was born in 1731 and in his life he suffered severe depression. He was an evangelical Christian which inspired him to writes hymn like poems. In 1773, Cowper was engaged to Mrs. Urwin, he experienced depression and thought that God wanted him to kill himself, so Miss Urwin didnt marry him, but told him to write poems to keep him occupied which he then wrote a few poems for a magazine and one was light shinning out of darkness, so you can see why his poem is a bit depressing. Williams poem says that life can be hard at times us that we should put it behind us and take courage from God, as he writes ye fearful saints, fresh courage take, the clouds ye so much dread, it has a optimistic side of the poem. It is a hopeful poem and very religious. However with Dover beach. It is very pessimistic and sad, how he thinks that the world is not very a happy world because not everyone believes in a religion and they have started to believe in science instead of goad, Matthew describes the misery of the human race when he hears the sea so I do think this is a very depressing piece of poem.

20 Criminal Terms You Should Know

20 Criminal Terms You Should Know 20 Criminal Terms You Should Know 20 Criminal Terms You Should Know By Maeve Maddox DISCLAIMER: This is a random list of frequently heard terms that relate to criminal activities. It is NOT comprehensive. It is NOT to be construed as legal advice. If you need reliable legal information, talk to a lawyer who practices law where you reside. Broadly speaking, U.S. law recognizes two types of crime: misdemeanor and felony. Not every state agrees as to the classification of misdemeanors and felonies. For example, in some states domestic abuse is a misdemeanor; in others its a felony. Nonetheless federal guidelines determine the difference between a felony and a misdemeanor in terms of punishment: a crime punished by imprisonment of a year or less is a misdemeanor. 1. arson: From Latin ardere, to burn (pp. arsus). Intentionally damaging a building with fire or explosives. 2. burglary: The crime of breaking into a house with intent to commit theft. Until some time ago this charge occurred only if the felon broke into the house at night. 3. crime: from Latin crimen, charge, indictment, offense. An act punishable by law, as being forbidden by statute or injurious to the public welfare. Legally, a crime consists of two parts: actus rea, the criminal action, and mens rea, the criminal intention. 4. domestic abuse: any act or threatened act against a person with whom an intimate relationship exists or existed, for example, spouse, boy/girlfriend, child. 5. embezzlement: from Anglo-Fr. embesiler to steal, cause to disappear. A person who appropriates to personal use money entrusted for another purpose commits embezzlement. 6. felony: as a term in common law from Old French felonie, wickedness, evil, treachery, perfidy, crime, cruelty, sin. Noun: felon; adjective: felonious. 7. forgery: The creation of a false written document or alteration of a genuine one, with the intent to defraud. 8. human trafficking: the crime of displacing people with a view to exploiting them. 9. kidnapping: a compound of kid (slang for child and nap, a variant of nab, to snatch away. The word first referred to the practice of stealing children or others in order to provide servants and workers for the American colonies. In current usage, the crime of kidnapping is the abduction of a person of any age with the intention of holding the person for ransom or for some other purpose. 10. larceny: from Latin latrocinium, robbery. The felonious taking and carrying away of the personal goods of another with intent to convert them to the takers use. The difference between grand larceny and petit larceny is one of the value (as defined by statute) of the stolen property. 11. manslaughter: from Old English mann, person+slaeht, act of killing. Manslaughter is the unlawful killing of a human being without malicious intent. Voluntary manslaughter is committed in the heat of passion, or while committing another felony. Involuntary manslaughter is the result of accident, such as vehicular manslaughter. 12. moral turpitude: turpitude is from a Latin word meaning vile, ugly, base, shameful. Defining the term in a legal sense is a slippery undertaking. Crimes of moral turpitude include: murder, voluntary manslaughter, rape, domestic violence, prostitution, embezzlement, arson, bribery, blackmal, perjury, and theft. 13. murder: from Old English morà °or. secret killing of a person. Murder is intentionally causing the death of another, either through premediation focused on a particular individual, or by extreme indifference to human life. First degree murder is defined by federal and state laws, which vary. 14. prostitution: from Latin prostituere, to expose to prostitutuion, to expose publicly. Commission of a sex act for money or some other thing of value. 15. receiving: accepting property for use, resale, or disposal that is thought or known by the receiver to have been stolen. 16. robbery: from Old French rober, from a Germanic source meaning to rob, spoil, plunder. Robbery is theft committed openly and with force. 17. stalking: With the sense pursue stealthily, the verb stalk comes from Old English stealcian, as in bestealcian to steal along. An early meaning of stalker was one who prowls for the purposes of theft. In todays usage, stalking is a crime that involves the intentional and repeated following and harrassing of another person to the extent that the targeted person fears bodily harm. 18. theft: depriving another of property. Theft implies subterfuge, while robbery is the open taking of property. Burglary is committed when the thief breaks into a building: 19. treason: AngloNorman treson from a Latin word meaning a handing over, surrender, and influenced by Old French trair betray. Treason is the crime of siding with the enemy, either to fight against ones own country, or to offer aid and comfort to the enemy. 20. trespass: from Old French trespasser, to pass beyond or across.

Free Essays on Marc Quinn ‘Self’

Marc Quinn ‘Self’ 1991; size 81.9 x 24.75 inches ‘Self’ is a blood head sculpture. The art movement, which Marc Quinn belongs to, is modern art. The piece Self is a very modern piece it was made in 1991. The first thing that strikes me about this piece is that it is unusual! The first thought that came into my head was how much blood did they use? And had anyone ever created anything like this before? When I gathered my research there was different opinions about the amount of blood used to create Marc Quinn’s’ ‘self’, some authors said he had used 8 pints and others said 9 pints. His own blood (extracted over a five-month period) into a silicone model of his head then placed inside a refrigerated and transparent Perspex cube. According to some of the research Marc Quinn’s sculptures perhaps more than any others have come to stand for wilful sensitivity to the body and mortality fostered by British art in the 90s. The literature believes Quinn has chosen to use his own body as a primary source, saying â€Å" the self is what one knows best and least at the same time, casting the body gives one the opportunity to see the ‘self.’ while Marc Quinn acknowledges that his work may be shocking, he does not consider himself to be a â€Å"shock artist†; instead, he is interested in unveiling a certain reality and using science as a means of facilitating a personal artistic statement. Some art and design journalists believed Self is known throughout the art world as a powerful icon and when there is articles about Marc Quinn’s work, it is often put in the forefront as a strong image. Marc Quinn states it is a great sculpture that gets people interested in his work, as it is a radical piece of art.

Imagery in Prose - Essay Example He wasn’t a rock star in a traditional meaning either (well, everybody knows those adored handsome guys following the sex, drugs and rock-n-roll motto); he didn’t earn a fortune of money and never grew vain. His fans found something disarming about his kind and easy-going manners, and everyone would sense something so familiar in his songs. He didn’t want to be famous worldwide and wasn’t obsessed with fame, he knew that it was a delusive thing. Now, hurrying to meet his fans (who were certainly the best fans in the world, he thought) at a charity concert, he thought about the legacy he wanted to leave: not because he was going to die, not at all. It was in his nature, this desire to be useful to the society, and he had so many plans and so many purposes. Miles wanted to communicate his message to people. â€Å"The legacy and the message,† he thought. â€Å"That’s what makes artists live forever in the minds of people. But is it enough? Is it enough to write a couple of mediocre songs? Guys like me are not starry enough to get themselves listened to.† If he shared these thoughts with his wife, she would surely say that he was too modest and underestimated his significance. Well, he did. The cellphone rang – it was Steve, the concert manager (he always communicated with all the staff himself). Miles picked up the call with his right hand, holding the driving wheel with the left one. The car lost traction on the icy turn and ran against the truck. The collision set the Range Rover afire. Everything was blurred in his eyes, and the last thing he saw before he fell into darkness was the strange fiery bird of red and gold hovering above him. Miles found himself standing near the cathedral of his hometown amidst the overwhelming crowd of grieving people dressed in black. The weather was lousy, cold rain falling from the leaden clouds; however,

Implementing Strategy and Managing Change and leadership Essay

Implementing Strategy and Managing Change and leadership - Essay Example Sjostrand and Tyrstrup (2001) strongly believe that managerial leadership is a dynamic ongoing social construction process and cannot be described as a single clear cut phenomenon. Leaders need to adopt according to the situation and motivate the followers to move with time. In the highly competitive environment, the transformational leadership is able to significantly impact the followers by empowering them through informed choices. Burn (2002) broadly describes transformational leaders as persons who are able to raise one another to higher level of motivation and morality. Indeed, such leaders especially in organizations are able to motivate and empowers the workforce to use informed choices in making rational decisions. Managing change within organization has become important aspect of business strategy. In the fast transforming environment, the contextual factors like technology, globalization, environment, diversification etc have significant impact on decision making process. T he transforming leadership therefore becomes key facilitator of managing change. It perceives workforce as human capital that can judiciously exploit changes for improved outcome and motivates the same through dissemination of information. (255) Answer 5b National indicators and performance indicators are commonly used in public sector organizations. The targets are quantified for public sector outputs that are eventually linked to performance (Pollitt, 2006). They are important criteria that lend credibility to the public service organization and demonstrate good value for money for the taxpayers. Indeed the performance indicators strongly support the controls and measures used for improving the performance of the corporate services. They also provide transparency in their working and helps link taxpayer’s money to the services provided by the organizations. While taxpayers’ value for money becomes major aspect in the public service, the same indicators, when applied within a non public/ government organization help them to improve and improvise the performance to gain competitive advantage within the industry. They also become important benchmark for quality of services and help to provide the organizations with strong leverage to deliver exemplary service in emergency operations. In an organization like fire and rescue service, the performance indicators help the workforce to improve their skills and competencies regarding various issues and factors related to emergency operations. The leadership initiatives, organizational competencies vis-a-vis technologies, environment parameters, security of people and place, health hazards and forging linkages with other agencies to better coordinate rescue operations during crisis. By evaluating their performance against the various parameters of operational efficiency, the organization is able to improve its services. Effective communication to coordinate the services of various stakeholders during emer gency remains the most important element of crisis management and the feedback process becomes critical indicator of performance. Indeed, the performance indicators are important tools that greatly enhance the efficiency of services rendered by organizations. (272) Answer 6a Successful organizations are equipped with exemplary managerial leadership. Traditional managers broadly worked within the well defined parameters of organization’

Critique of Psychoanalytic Literacy Criticism Research Paper

Critique of Psychoanalytic Literacy Criticism - Research Paper Example In psychoanalytic criticism, the intention of the analyst is the overall background of the author and how it might have speculatively influenced the work of the same author. It also identifies the fact that the difference between these subjects of psychological and psychoanalytic criticisms is broadly similar and could be addressed by three main facts about this form of analysis. The facts are to do with the unconscious mental process of an individual. This includes the fact that human behavior is being motivated by own sexuality and the norm that are associated with sexuality in different cultures shaping or repressing the desire of these individuals. In Freud’s original argument, the process of dreaming is controlled by the sub-conscious mind and cannot be manifested in the wake status of an individual. However, according to Lacan, one of the proponents and developers of the psychoanalytic criticism, the sub-conscious mind can be manifested in the wake status. This can be derived from the comments that individuals joke with or the slips of the tongue or other unintended actions like puns. The works by Lacan further developed the concept of psyc hoanalytic criticisms that has evolved over time to be employed in different forms of art. The concept of psychoanalytic literary criticism is the psychoanalysis of the author or a particular interesting character is a given work. Just like other forms of literary criticism, psychoanalytic criticism can results to important clues to the something baffling symbols actions and setting s of literary work. Early psychoanalytic literary criticism most of the time treat the text as if it were a kind of a dream. That is; the text inhibits its original content beyond obvious content. It is worth noting that this process of changing the text is regarded as dream work and is characterized by concentration and displacement. Critics consider language and symbolism of a text to reverse the process of the dream and instead

Eating Disorder Case Study

Eating Disorder Case Study ‘When normal eating becomes abnormal’ Eating is a crucial activity for humans, as the food we consume acts to provide us with the fuel we need to keep our bodies running, and to live our daily lives. Normal levels of eating can be characterised as consuming just enough calories (of energy) to allow us to function as we require, and not to have so much left over that is not used and subsequently stored as fat cells. Exactly what level is characterised will vary on an individual-to-individual basis, as ‘normal’ will be subject to individual differences such as activity levels, age and metabolic rate, which can all affect the rate at which energy is used or stored by the body. Abnormal eating can thus be seen to occur when we either consume too much or too little energy (food) for what we need, and forms the basis of negative eating behaviour, classed as eating disorders. There are two main eating disorders; anorexia nervosa, and bulimia. Anorexia is perhaps the most well-known of the disorders, and attracts a great deal of media coverage and celebrity profiles associated with the condition such as Victoria Beckham, Calistra Flockheart and the Olsen twins (Mary-Kate and Ashley). Characterised by deliberate and extreme weight loss through the withholding of hold often to the point of emaciation, anorexics will constantly worry about food, with such cognitions visible through behaviours such as obsessive weighing and calorie counting and abnormal levels of control in regards to food. Self-image is chronically out of touch with reality, with individuals at the later stages of the condition still seeing their body as fat, despite being seriously underweight. Through this self-inflicted starvation, the anorexic will start to experience physical symptoms and problems such as stomach pains, growth stunting, osteoporosis and reproduction problems such as the stopping of periods in women, or infertility in men. In the long term, lack of food can be serious to health, with the possibility of leading to kidney, liver and even heart damage, and thus the condition can be fatal. Bulimia is a more common disorder than anorexia and in contrast to the strict self-control of eating regulated by anorexics, bulimia can occur as a result of a lack of control over eating. Bulimics do not starve themselves, instead will binge massive amounts of food (often secretly), and with some cases reported as ingesting as much as 15,000 calories in 1 – 2 hours. After eating until they feel ill, bulimics will then use methods such as vomiting or laxatives to purge themselves of the calories that they have ingested. Physical effects of bulimia can be harder to detect as there is usually no dramatic weight loss, and in many cases is simply the maintenance of weight despite the food binges they have. Associated physical problems include sore and inflamed throat as a result of induced vomiting, which may eventually lead to a difficulty in swallowing. Stomach acid brought up along with food will also cause problems such as burning of the oesophagus and the damaging of tooth en amel. Intestine function can break down when forced repeatedly to expel food; dehydration can occur due to loss of fluids, and when to a serious enough degree can upset the balance of chemicals within the blood with minor consequences including dizziness, and the most serious being heart failure. Bulimia is a condition that is intricately linked with emotions and psychological well-being. Anxiety and unhappiness can binges which then cause guilt and further unhappiness until alleviated by purging. The sufferer is thus trapped in a vicious circle. One of the most high profile cases of bulimia is likely to be that of Princess Diana. Quoted as saying the bulimia was â€Å"a symptom of what was going on in my marriage. I was crying out for help, but giving the wrong signals,† (Panorma, BBC TV, 1995) such a comment is a prime example of the psychological nature of the condition. The difficulty in treatment of bulimia is that emotionally the action of purging is reinforcing by alleviating the guilt and unhappiness felt after a binging session, and thus makes the cycle far harder to break. Most cases of these eating disorders will start during adolescence or early adulthood, and are strongly linked in the literature and media as associated to psychological issues. Personal aspects such as perfectionism, identity and sexuality and self-esteem are strongly correlated factors, with control issues – whether in regards to excessive restraint, or in loss of control over eating, also have a predominant role. Along side these personality traits, the concept of body image, and how it is portrayed is felt to play a major contributing factor to the continued existence and rise of eating disorders. Weight is often seen as a measure of self-worth, attractiveness and sexuality, and subsequently this is modelled by the rich and famous that many adolescents look up to. Whether modelled in movies such as Demi Moore in Charlie’s Angels, or in fashion and celebrity magazines such as Vogue or Heat, young people are surrounded by visual media with images of the perfect body a nd what it means to be attractive and (subsequently associated) successful, and will unsurprisingly want to achieve this. When younger people do not feel that they match up to this notion of beauty, this can act as the psychological trigger to any of the conditions mentioned. The spread of eating disorders across the world alongside Westernisation to continents once free of such conditions, has further demonstrated the role that culture exerts over these diseases. Communication technologies such as the internet have also made the transfer of information such as tricks and tips between sufferers easier by connecting a once hidden and isolated population, the so called ‘Pro-ana (Anorexia) and Pro-mia (Bulimia)’ websites and chat rooms, which may also reinforce sufferer through the social support system such ‘societies and groups’ entail. Role of the media in the message it send out about eating disorders is thus mixed – articles in the written press ap pear to be condoning the behaviour, and yet reading behind the lines often eludes to something else A profile article on Calistra Flockhart in Hello! Magazine describes her anorexia, and yet in the same sentence tells how her ‘look’ is what landed her the role in the TV series Ally McBeal. Men’s magazines such as FHM and Loaded run annual ratings of the most attractive women, and subsequently reinforce the male attitude of thinness as attractive, and women see this as further example of how they believe they are expected to look. However there is evidence for optimism that that there is a shift in the ideology of beauty previously characterised in the 1990’s as the ‘waif supermodel look’ of Kate Moss and Jodie Kidd. Stars such as Beyonce and Jenifer Lopez are beginning to change the boundaries of attractiveness, reinventing the look of the womanly figure and curves.

Personal Narrative - My Dad, Formally Known as Superhero :: Personal Narrative Writing

My Dad, Formally Known as Superhero When I was twelve, I started fasting on Yom Kippur. That was the year I had my Bat Mitzvah and the year I became a Jewish woman. In the few years before I turned twelve, I ate sparingly on that holiest day - no junk food, no breakfast. And in the years before that, I ate whatever I wanted. My mom too. She's not Jewish - she just happened to marry my Jewish dad. My dad always fasted. He'd go to Temple in the morning, and we'd go with him - me, my sister, and my mom. My sister was a baby, and I sat on the floor and colored my coloring books on the metal chair I was supposed to be sitting in, which pleased my parents because I didn't make noise. At one or so, we'd leave Temple and drive home. The car windows would be rolled up tight, locking in the rays of the early afternoon sun, and I would bask, free and alive, dressed up and soaking in the sun's light. The sunshine really does look different in the very middle of the day. When we got home, my mom would make me a snack, and I'd go off and play or something. I don't really remember. My dad would nap, or read. I do remember that. He was no fun on Yom Kippur. A few years later, I think I must have been about nine. We got home from Temple, and the kitchen was lit by that hot and yellow midday sunshine. Our striped curtains hung eagerly. My dad lay down on the living room couch and picked up his book, and my mom flipped through some papers on the kitchen table. Or maybe she was downstairs. It doesn't matter. I opened the refrigerator and pulled out the fruit drawer at the bottom. There were four granny smiths lying in wait. I picked the best one and rinsed it in the sink. It was the biggest, the roundest, the firmest. The grassiest green. It promised to be the juiciest. I grabbed the towel from the oven door and dried it. I slid on my socks across the kitchen floor and into the living room and bit down, hard. It was a huge bite. A huge cruncher! That bite echoed around the whole house - into the bedrooms and into the bathrooms; it attacked my dad on the couch, and probably even rocketed the neighbors.

Cambodia Typical Families Essay

Most of the people of Cambodia live in villages and farm the land or fish to obtain their food. To see the real life and culture of how over three- quarters of the people of Cambodia live, you have to leave the cities and visit the villages. Houses are either in groups or strung out along a canal, river road or hillside. They are the source of Cambodian pride and satisfaction. All major events – birth, marriage, and death – occur within the villages. Cambodians are very shy people but very warm and welcoming to visitors. Their society is conservative, and centered around the family and religion. However, Cambodia is one of the poorest countries in Asia, with an average daily income of approximately US$1.30 a day. More than 80% of the people of Cambodia follow a traditional lifestyle in the countryside. The main occupants of a village are farmers and their families engage in traditional agriculture on small farm lots. The majority of farmers live in permanent villages known as sedentary villages. It may look idyllic, but subsistence farming is very hard. Most grow rice and basic crops. Each morning you can see workers walking to the fields carrying their tools and leading their water buffalo or cattle. At sunset they return to the shelter of the villages. Other villagers live in temporary shelters until the end of the growing season when they return to a village that is more permanent but which may be moved if new land is needed. These people are called shifting cultivators and they live in the more rugged upland areas. These people mostly belong to hill-tribes of Cambodia and live in the North-eastern provinces. Like almost all other countries in Asia, the Cambodian people’s main food is rice. Cambodian peasants have planted rice ever since the time of the Angkor Empire. At the present time they still implement their traditional techniques. Cambodia has a geographical advantage and is extremely blessed with good water resources. The people in the countryside still plant their rice seasonally. The most common time they would plant is in the wet or monsoon season. In the dry season, the only farmers who can plant their rice paddy fields are those near water. About 10% of the people of Cambodian run small businesses from their ‘shop houses’ (The front of their house is the shop, and the family lives behind this or above on the first story) and about 8% of people work for the government. Visitors will notice a huge gap between rich and poor. A few Cambodians are very rich, with big houses, expensive cars and servants, while the very poor live in small thatched houses and do not even have a bicycle. Country life follows the rhythm of the seasons around planting and harvesting the crops. After the rainy season you will see people climbing palm trees to obtain palm juice to make palm sugar. You can also see them fishing in the rivers and lakes to supplement their income. As in most other countries, rural people tend to marry younger (18 – 25 years for men and 16 – 20 years for women) and have more children (3 – 5). In contrast, urban men marry at 25 – 35ys of age and women at 20 – 25yrs and rarely have more than 3 children. Cambodians usually have 3 meals a day. Rice in some form is eaten at nearly every meal. Fish is the main protein. Poor people may have to make do with cold rice (left over from lunch time) and fish sauce for their evening meal. Despite the hardships of recent years, adult literacy has risen to 65%. It greatly varies over the country, and sadly less girls than boys continue with their education. Cambodia is experiencing a resurgence of traditional arts, especially classical dancing which was performed at the palace and folk dancing.

The stairss in mensurating the nutritionary content of eating house repasts are far harder to cipher and show.

There are many types of eating houses and each type should be given a opportunity to supply their ain alone method to supply nutritionary informations. Seventy per centum ofeating house clients opt to custom-make their repasts. As such. any ingredient that they opt to take from their nutrient pick will do a important alteration in the nutritionary content of the full nutrient bundle.

Sistine Chapel Essays

Sistine Chapel Essays Sistine Chapel Essay Sistine Chapel Essay The Frescos in the Sistine Chapel Michelangelo was an amazing painter and sculptor, who made an impact on the Renaissance Era. The Renaissance focused immense passion towards the arts, religion, and individual experience and development. The Renaissance Era came after the Middle Ages, which possessed a completely opposite lifestyle and different art techniques and characteristics. The Middle Ages was a dark, depressing time where art had very little importance outside the art in the church. As Italy evolved from the Middle Ages into the Renaissance, specific attention was placed on humanism, realism, a transformation in art, and a different focus on biblical aspects that would forever characterize this time period as seen in Michelangelo’s work, The Sistine Chapel. With Michelangelo living during the Renaissance, humanism and realism had an effect on how he painted, and what profession he chose. Michelangelo’s father, Ludovico Buonarrotiwith, was a Florentine official with strong connections to the Medici family. In his childhood, Michelangelo was constantly around the Medici household, and surrounded himself with humanists like Marsilio Ficino and Angelo Poliziano, which influenced his way of thinking. Humanism is a philosophy or practice that focuses on how great humans can be. Man should gain the most knowledge possible, and become the finest they can be physically and mentally. Humanism is all about studying, learning, thinking, and becoming better as a man. Clearly embracing the idea of humanism, Michelangelo painted every character as strong and flawless. Every human painted on the walls of the Sistine Chapel has chiseled muscles, with clear six-pack chests and abs. Michelangelo illustrates how humans are the best thing God has created, and portrays them as great. The human body is considered the â€Å"noblest living form† by humanist, and humans have full potential physically and mentally. Humanism creates a universal man who is intellectually and physically excellent and who is always honorable and virtuous. On the walls of the Sistine Chapel, the realism of humans is depicted with scenes full of human emotion and expression. Embracing the â€Å"Enlightenment† by exploring his world around him, Michelangelo moved away from a static, lifeless art style to one that highlighted human feelings and movement. Realism at this time led to the later Realism of the 19th century, where the greatness of the ordinary man became the focus of artwork. During the Renaissance, the idea of expression and emotion infiltrated the culture changing the people’s way of thinking and also the art. Michelangelo’s Sistine chapel illustrations relate to Biblical stories, and show more of a natural and authentic human perspective. The new style of art in Michelangelo’s life gave him the opportunity to paint the Sistine Chapel in a very natural and real way with all the focus on man. In the medieval times, art was abstract, dark, and heavy. Art was viewed with a completely different perspective. The medieval time was not focused on artwork, and members of the upper class were not willing to pay for artists to paint. Most artists worked for the church because the church was the only one who would pay. The church wanted art dealing with Christian aspects, so most art was religious. Medieval art typically didn’t use shading as a tool to enhance paintings. The art was normally not too colorful, and was often very dull. Unlike Michelangelo’s work on the Sistine Chapel, Medieval art was not focused on human qualities. During the Renaissance, many upper class citizens had a sudden interest for art, and many of them would hire artists to paint for them. With the new interest in art, new styles were formed, creating more unique styles and new ways of thinking. With the change to the Renaissance art style, Michelangelo’s showed the body in movement, and illustrated the nature of humans. Michelangelo used new techniques like perspective and more detail in humans to make his frescos more emotional to the viewer. He illustrated characters with little to no clothing, which was not a style in medieval art. His paintings on the walls are a great example of the Renaissance art, and show the evolution, and how far art came in such a quick time. The Sistine Chapel is home to one of the most famous pictorial artworks ever made. The walls are breathtaking, and create such an astounding Biblical presence. Pope Julius II called Michelangelo into Rome in hopes to paint the Sistine chapel. He was trying to rebuild after destruction in the city, and also worked on repairing St. Peter’s Basilica. Michelangelo was hesitant to accept the offer because he was more into sculptures, but he was left with no other choice but to accept. The walls in the Chapel hold 9 scenes from Genesis, the first book in the Bible. The frescos show God separating light and darkness, creating Adam and Eve, and more Biblical stories. Each human painted on the wall shows emotion and truly represents the stories properly. Michelangelo used new Renaissance tools and a new Renaissance way of hinking to paint a new style that has attracted people from all over the world. An average of 10,000 people travel to see the Sistine Chapel a day. Michelangelo spent years preparing for this task, and drew out each scene before it was painted. Each part of the Sistine Chapel is natural in reality, and shows more of a realistic side to Bible scenes and people than previous art. Michelangelo was considered to be the best High Renaissance artist, along with Leonardo Da Vinci. With the fame he had, many citizens would travel to see his work. With the immense amount of viewers each day, it allowed for more to see Christianity in a visual way, and helped convert countless people. People would have a strong connection to his art, and grow closer to God with seeing such beauty. Michelangelo’s work created a new way of viewing Christian art, and it allowed some to put more faith in God. Pope Julius II brought Michelangelo in to paint the Sistine Chapel in hopes that it would help restore Rome to its former glory. Michelangelo’s hard work paid off with its gigantic popularity when he first painted it, and that is still as strong today. Michelangelo is considered to be the â€Å"Renaissance Man,† and used his new styles and techniques to illustrate such beautiful scenes onto the walls and ceiling of the Sistine Chapel. He used a very real and natural body to portray realism. He showed every character with clear and strong muscles with very little clothing to show how strong and valiant humans are. His style is very unique and different from artists who had come before him. Michelangelo’s Sistine Chapel is still today a very beautiful and breath-taking scene that helped separate modern artwork from the medieval art.

Wireless Technologies Proposal Coursework Example | Topics and Well Written Essays - 500 words

Wireless Technologies Proposal - Coursework Example The data could be in the form of voice that a Bluetooth enabled speaker system that can play the voice directly or can be utilized for the conversation between the two persons. Bluetooth is a wireless communication technology that has a short range. It can be utilized to transmit and receive data (Morrow 2002). The Bluetooth can maintain a personal area network (PAN), which is a highly secure networking topology. In this network, only the assigned users can send or receive data, no other user is allowed to enter the network with the permission of the administrator. Bluetooth is a pity common technology that is being utilized to transfer data in the mobiles phones and note book PCs. As the range of Bluetooth is quite less not more than 110m, it is best suited for the Party Plates Organization. It has certain advantages as if it is easy to be utilized, easy to manage, easier to send and receive data and easier to create a Personal area network but the major disadvantage of the Bluetooth is the short range of the Bluetooth. The signal fades out as the user goes far from the sender. The second technology that I will recommend to the Party Plates Organization is the Wireless Fidelity (Wi-Fi) or Wifi is a wireless technology that has made its place with the existing other wireless technologies. It works utilizing the principles of the Local Area Network (LAN). It is utilized to establish a connection between the wireless (Wifi) LAN enabled Note book PC, Personal computer, Mp3 player or a mobile phone and internet. Like the Bluetooth, it has a short range too. An indoor Wifi modem has a range of about 30 meters while the outdoor Wifi modems have a higher range. There are certain advantages of the Wifi over other wireless communication systems. The main advantage of the Wifi communication system is that it could connect a number of users using the same access point. Other advantages like enhanced data

Progression in History Essay Example | Topics and Well Written Essays - 750 words

Progression in History - Essay Example We have almost everything at the tip of fingers. The use of science and technology has created doors for us to discover a lot of things, like in the field of investigation wherein we now have advanced tools that can recreate bullet impacts or match DNA just from a single hair strand or even just a small piece of skin. Digital imaging help recreate faces from the skulls buried long ago and excavated days ago. We have gone a long way in terms of science and technology but have we progressed or have we just adapted to the times? Through this paper, I seek to deliberate whether there is human progression or just adaptation. The different periods in time, from the Old Age to the Modern era, shows us that humans are pursuing different areas of development. We have expansion, arts and culture, science and technology and even political dominion. The different periods in time give us a glimpse on how human life has moved from one dimension to another. So is there progress or do we regress fro m time to time that’s why we look back at history and rediscover things? The Machiavellian notion of human progress is associated with the fixed human nature, that human nature is geared towards change and development because of desire and ambition (Gutfreund, 208). With this, Machiavelli sees progress as a goal, an end result that moves towards man’s ambition and desire to become better and more powerful. This indicates that human progress is not fixed rather than an effect of the human fixed on it nature (Lemon, 105). For Machiavelli, there is no real progress in human history, rather, there is a continuous experience, by which, we learn, grow, and move towards our ambition and desire. There is no such thing as meaning in history, only learning, as human experiences are guided by human nature, a clear statement that indicates that progress is non-existent and what humans experience are their natural-born instincts. This is partly what I personally believe as human pr ogress. That it is associated with human nature. But I don’t agree with Machiavelli that human nature is fixed and unchanging towards desire and ambition. Because of experience and learning, humans develop, mature and change. For me, progress means to change for the better. It means development and improvement. But it is more than that, progress is a combination of stability, change and growth. With this, I agree with Luther’s notion of progress and its relation to a struggle. For Luther, progress is a goal towards justice, by which humans need to sacrifice and to suffer before being able to reach it (Paulson, 90). Luther’s progress is a goal towards justice and equality. His progress is idealistic. With this, it contradicts with my belief that progress is associated with human nature. Human nature is not idealistic. It has flaws, that’s why humans need to look back and understand the past and use these learnings in order to move towards progression. But human’s are not perfect and ideal, that’s why we always regress to old habits and make the same mistakes. Progress, then, is a continuous struggle, but not to Luther’s goal of justice and equality, but to human’s desire to become better. Bacon’s belief in the notion of progress created an idea that technological advancement is associated to progress (Attar, 70). For him, science and technology are the means to control nature, that humans can

International Business - Essay Example International Business As organisations begin to operate in foreign markets structural and environmental complexity and uncertainty increases. "If the domestic environment can be labelled uncertain, the international business environment is doubly so." (Mascarenhas 1982) International managers must know that international business environment is multidimensional that includes cultural differences, political risks, exchange risks, legal and taxation regulations. According to Mascarenhas the multiple factors a multinational faces due to environmental uncertainty are foreign exchange uncertainty, political uncertainty, and employment problems. However most experts of international business environment believe that it can be classified into four categories: administrative, engineering, entrepreneurial, and regulatory. More recently, Guisinger (2001) has put forward some of the main features of international business environment. They are: culture, legal system, political risk, income profile, tax regimes, exch ange rate, and restrictions. Culture may be described as the values, beliefs and attitudes of a country. These tell apart one country from another. International managers need to be aware of this while they travel, communicate or negotiates with people of other countries. Cultural differences are extremely important. An organization must give top priority to learning the foreign countrys proper cultural practices as well as cultural taboo.

Outline Current Legislation Affecting the Safeguarding of Children and Young People Essay Example for Free

Outline Current Legislation Affecting the Safeguarding of Children and Young People Essay â€Å"Safeguarding and promoting the welfare of children is defined as: †¢protecting children from maltreatment †¢preventing impairment of children’s health or development †¢ensuring children are growing up in circumstances consistent with the provision of safe and effective care. â€Å" (Dept for Education www.education.gov.uk) There are numerous laws and guidelines in place which aim to protect children from harm, and promote their health and wellbeing. The need for improved legislation has been highlighted by high-profile cases, such as the death of Maria Colwell in 1973 and, more recently, Victoria Climbià © in 2000. These cases shocked the nation and showed weaknesses in procedures. These policies are constantly reviewed and amended so it is important to keep up to date with these changes. The Children Act 1989 This Act identifies the responsibilities of parents and professionals who must work to ensure the safety of the child. This Act includes two important sections which focus specifically on child protection. Section 47 states that the Local Authority has ‘a duty to investigate when there is a reasonable cause to suspect that a child is suffering, or likely to suffer, significant harm’. Section 17 states that services must be put into place to ‘safeguard and promote the welfare of children within the area who are in need’. The Education Act 2002 This outlines the role of Local Education Authorities (LEAs), governing bodies, head teachers and all those working in schools to ensure that children are safe and free from harm. The Children Act 2004 This is not a replacement of the Children Act 1989. This provides the legal framework for Every Child Matters and sets out the process for providing services in a way which allows every child to achieve the five outcomes of Every Child Matters (described below). It requires local authorities to lead multi-agency children’s trusts, to develop a children and young people’s plan, and to set up a shared database containing information relevant to a child’s welfare. This allows all the organisations involved in children’s welfare to access relevant information and work together to provide the best possible service. Childcare Act 2006 This act aimed to transform early years and childcare services in England. Local authorities are required to: †¢Improve the Every Child Matters outcomes for pre-school children †¢Provide sufficient quality childcare for working parents. †¢Provide a better Parent Information Service. Every Child Matters This was launched in 2002, at least partly in response to the death of Victoria Climbià ©. It is one of the most important policy initiative and development programmes in relation to children and childrens services of the last decade. It has been the title of three government papers, leading to the Children Act 2004. Every Child Matters covers children and young adults up to the age of 19. Its main aims are for every child, whatever their background or circumstances, to have the support they need to: †¢Be healthy  Ã¢â‚¬ ¢Stay safe †¢Enjoy and achieve †¢Make a positive contribution †¢Achieve economic well-being Each of these themes has a detailed framework attached whose outcomes require multi-agency partnerships working together to achieve. The agencies in partnership may include childrens centres, early years, schools, childrens social services, primary and secondary health services, and Child and Adolescent Mental Health services (CAMHS). In the past it has been argued that children and families have received poorer services because of the failure of professionals to understand each others roles or to work together effectively in a multi-disciplinary manner. Every Child Matters seeks to change this, stressing that all professionals working with children should be aware of the contribution that could be made by their own and each others services. Protecting children from harm can be best achieved by effective joint and partnership working between agencies. Working Together to Safeguard Children This provides guidance on what you should do if you have concerns about the welfare of a child. It also recommends ways of working for people who work with young people and their families. What to do if You’re Worried a Child is Being Abused (DfES 2003) This is a guide for practitioners, helping them understand how to work together to promote children’s welfare and protect them from harm. It reinforces Every Child Matters by stressing the importance of joint working. United Nations Convention in The Rights of The Child 1989 This treaty sets out the rights and freedoms of all children in a set of 54 articles. Included in those rights are those which ensure that children are safe and looked after. Article 19 states children’s rights to be ‘protected from all forms of physical or mental violence, injury or abuse, neglect or negligent treatment, maltreatment or exploitation including sexual abuse by those looking after them’. Those countries which signed up to the Treaty, including the UK in 1991, are legally bound to implement legislation which supports each of the articles.

Application Of Types Of Lubricant

Application Of Types Of Lubricant A lubricant is a substance (often a liquid) introduced between two moving surfaces to reduce the friction between them, improving efficiency and reducing wear. They may also have the function of dissolving or transporting foreign particles and of distributing heat. Basically there are many types of lubricants; solid lubricant, liquid lubricant and gaseous lubricant. They have their own purpose and application. They are as follows: Purposes: Almost all the Lubricants perform the following key functions. Keep moving parts apart Reduce friction Transfer heat Carry away contaminants debris Transmit power Protect against wear Prevent corrosion Seal for gasses Stop the risk of smoke and fire of objects Applications: Application of Semisolid and Solid Lubricants Grease lubricants are semisolid and have several important advantages: They resist being squeezed out, they are useful under heavy load conditions and in inaccessible parts where the supply of lubricant cannot easily be renewed, and they tend to form a crust that prevents the entry of dirt or grit between contact surfaces. Grease is a mixture of a lubricant and a thickener; often it is made from a mineral oil and a soap. It may be applied in various ways: by packing enclosed parts with it, by pressing it onto moving parts from an adjacent well, by forcing it through grease cups by a spring device, and by pumping it through pressure guns. Solid lubricants are especially useful at high and low temperatures, in high vacuums, and in other applications where oil is not suitable; common solid lubricants are graphite and molybdenum disulfide. Application of Liquid Lubricants Liquid lubricants may be characterized in many different ways. One of the most common ways is by the type of base oil used. Following are the most common types. Lanolin (wool grease, natural water repellant) Water Mineral oils Vegetable (natural oil) Synthetic oils Other liquids Mechanical devices to supply lubricants are called lubricators. A simple form of lubricator is a container mounted over a bearing or other part and provided with a hole or an adjustable valve through which the lubricant is gravity-fed at the desired rate of flow. Wick-feed oilers are placed under moving parts, and by pressing against them they feed oil by capillary action. Horizontal bearings are frequently oiled by a rotating ring or chain that carries oil from a reservoir in the bearing housing and distributes it along the bearing through grooves or channels. Bath oiling is useful where an oil-tight reservoir can be provided in which the bearing journal may be submerged; the pool of oil helps to carry away heat from contact surfaces. Splash-oiling devices are used where gears, bearings, or other parts contained in housings have moving parts that dip into the lubricant and splash it on the bearings or into distribution channels. Centralized oiling systems usually consist of a reserv oir, pump, and tubes through which oil is circulated, while heaters or coolers may be introduced to change the viscosity of the lubricant for various parts of the system. Many oiling operations are automatically synchronized to start and stop with the machinery. P2) Describe the operation and maintenance of three different lubrication systems. Oil lubricating systems can be divided into three categories: Total loss. Self contained. Re-circulating. Total loss: lubrication points are always supplied with fresh lubricant (oil, fluid grease or grease) at specific intervals (time or machine cycle-dependent) during the lubricating cycle. It is the only system that allows the lubricating oil to drain away or evaporate. Self contained : With self contained lubrication, the oil is contained in a reservoir. A gearbox of a vehicle or a lathe is lubricated in this way. The gear are partly submerged in the oil, this process is called splash lubrication. Oil is carried up to the parts that are not submerged, and an oil mist is created inside the gearbox. Ring oiling is another self contained system in which the oil from a reservoir is carried up to the rotating parts of a mechanism. The ring which is rotating with a shaft is partly submerged in the oil and carries it up to the shaft bearings. Re-circulating: With re-circulating system, the oil from a reservoir is fed under pressure direct to the moving parts or delivered as a spray. The flow is continuous and after passing over the contact surfaces, the oil runs back into the reservoir under the effects of gravity. Maintainance: Oil lubrication systems should be checked weekly. This can be carried out by plant operators or maintenance engineering. If needed the tank or reservoir can be topped up taking care not to let any dirt into the system during the process. Systems should not be overfilled as this might caused increases resistance to splash lubricated parts. It might also lead up to overheating of the oil due to excessive churning. Dip sticks and sight gauges are usually provided to indicate the correct level or depth in reservoirs. Samples of lubricating oil are taken for laboratory analysis at regular intervals as part of a condition monitoring procedure. They are examined to see if they contain any solid wear particles. This can provide useful information to the plant manager and maintenance engineer as to the condition of the plant and machinery. All lubricating oils degrade over a period of time due to oxidation. They should be changed including the filters in a re-circulating system. Human should be careful of lubricating oils, since it can cause skin irritation, it can also lead up to cancer. So humans should always use safety equipments and should also wear protective clothing and maybe goggles for the eyes, when handling lubricating oils. References: http://en.wikipedia.org/wiki/Lubricant, engineering book P3) Describe the operation of one seal, one type of packing and two different types of bearing with a typical application for each one. Seals: For the task , I will be doing oil seal. Oil seals are flange packing having an elastomer lip bonded to a metal cup, these lips are loaded to accommodate shaft running out and helps in sealing. There are two types of oil seals. Single seals , which are recommended only for non-pressure service and are best against good lubricating media. And the other one is double sealing, which are normally used to handle pressure in eiher direction along the shaft. The main function of oil seal is to stop whatever fluid is inside from leaking out the clearance between the shaft and housing. Packing For packing, I will be explaining about gland packing seals. they are usually made of cotton, asbestos, flax or jute. In this packing, compressed synthetic fibers are also used and sometimes impregnated with graphite to assist lubrication. It has the advantage to withstand higher internal pressures than lip seals. in this packing, a collar is tightened so that packing material forms a seal around the shaft. A little amount of water for lubrication and cooling the packing is also allowed to drip to the atmosphere. It is normally used as a seal for both rotating and reciprocating shafts. Bearing: The purpose of the bearing is to support and locate rotating and reciprocating shafts or parts in machines and is to transmit force from one member to the other while allowing their relative motion/ movement to occur with the minimum resistance to motion. Two bearing I will choose for this task are plain bearing and roller bearing. Plain bearing: it is a typical bearing made of two parts. For e.g. a rotary plain bearing can be just a shaft through hole. A simple bearing can be pair of flat designed to allow motion. It has flat , cylindrical or spherical surfaces which slide relative to each other. It can be used to carry load in one of several ways depending on their operating conditions, surface, clearance and temperature. It may be used to comprise a rotating collar with a flat surface loaded against a plain or grooved thrust ring. It is also designed to withstand the forcve acting along the axis of the shaft, parallel to the axis of rotation. Roller bearing: this bearing carries a load by placing round elements between the two pieces. The relative motion of the pieces causes the round elements to roll with very little rolling resistance and with little sliding. A rolling element rotary bearing uses a shaft a much larger hole and cylinders called rollers tightly fill the space between shaft and hole. The bearing are often used for axles due to their low rolling friction. References: handout given by teachers P4) Describe two different types of screwed fastening and two different types of rivet giving a typical application for each one. Screwed fastening are used to make semi permanent joints which allow access and removal of fastened parts for maintenance and/or repairs. There are many types of screwed fastening of which the two I am going to mention here are nuts and studs and set screws. stud and nuts: it is a length of bar which has been threaded at each end, the shorter threaded end is screwed into the major component. It is used for inspecting machine cover needs to be removed regularly for maintenance purpose. Set screws: it is also known as machine screws however it does not used a nut. It is usually used to join a thin plate to a larger component. Screws are available with different shapes of head for different applications. It can be used as locking devices. P6)Describe the arrangement and operation of two different kinds of belt drive, two different kinds of chain drive and two different kinds of gear train. A) Belt drive: A belt drive is a method of transferring rotary motion between two shafts. A belt drive includes one pulley on each shaft and one or more continuous belts over the two pulleys. The motion of the driving pulley is, generally, transferred to the driven pulley via the friction between the belt and the pulley. Synchronous/timing belts have teeth and therefore do not depend on friction. Belt drives and gear transmissions have a much greater life expectancy than belt drives. Belt drives also have relatively high inspection and maintenance demands. There are many types of belt in which I am going to explain two of them; 1) Round belts Round belts are a circular cross section belt designed to run in a pulley with a circular (or near circular) groove. They are for use in low torque situations and may be purchased in various lengths or cut to length and joined, either by a staple, gluing or welding (in the case of polyurethane). Early sewing machines utilized a leather belt, joined either by a metal staple or glued, to great effect. 2) Ribbed belt A ribbed belt is a power transmission belt featuring lengthwise grooves. It operates from contact between the ribs of the belt and the grooves in the pulley. Its single-piece structure it reported to offer an even distribution of tension across the width of the pulley where the belt is in contact, a power range up to 600 kW, a high speed ratio, serpentine drives (possibility to drive off the back of the belt), long life, stability and homogeneity of the drive tension, and reduced vibration. The ribbed belt may be fitted on various applications : compressors, fitness bikes, agricultural machinery, food mixers, washing machines, lawn mowers, etc B) Chain drive: Device widely used for the transmission of power where shafts are separated at distances greater than that for which gears are practical. In such cases, sprockets (wheels with teeth shaped to mesh with a chain) take the place of gears and drive one another by means of a chain passing over the sprocket teeth. The chains used in conveyor belts are commonly block chains, and consist of solid or laminated blocks connected by side plates and pins. The blocks engage with teeth on sprocket wheels. Depending on the material being moved, buckets, hooks, or other devices are connected to the blocks. 1) Roller Chain: Motion transmitted using shaft mounted sprockets. Simplex chain consists of length of single links, duplex is length of double links, triplex is length of triple links. Chain drives should ideally be lubricated and regularly cleaned . However experience shows that this drive method will work for long periods without lubrication or maintenance 2) Inverted Tooth: Also called silent. Motion transferred via shaft mounted pinions (similar to gear wheels.) Higher power power capacities, higher speeds and smoother operation. These drive system definitely requires lubrication. (Oil bath, or spray.) C) Gear train: A combination of two or more gears used to transmit motion between two rotating shafts or between a shaft and a slide. It is a set or system of gears arranged to transfer rotational torque from one part of a mechanical system to another. 1) Simple Gear Train:It is made of few components, a small gear at the centre called the sun, several medium sized gears called the planets and a large external gear called the ring gear. The planet gear rolls and revolves about the sun gear and the ring gear rolls on the planet gear. 2) Simple Gear Train:The most common of the gear train is the gear pair connecting parallel shafts. The teeth of this type can be spur, helical or herringbone. The angular velocity is simply the reverse of the tooth ratio. The main limitation of a simple gear train is that the maximum speed change ratio is 10:1. For larger ratio, large size of gear trains are required. The sprockets and chain in the bicycle is an example of simple gear train. P7 Describe the arrangement and operation of two different kinds of transmission shaft and coupling, two different kinds of clutch and two different kinds of brake transmission shaft rotating shaft that transmits rotary motion from the engine to the differential Different types of shafts: Plain transmission Stepped shaft Machine tool spindle Railway rotating axle Non-rotating axle Crankshaft Propeller shaft Crankshaft The crankshaft is that part of an engine which converts linear piston motion into rotation. The crank and connecting rod mechanism was first used in Roman water mills, to convert the reciprocating motion into rotation, the crankshaft has crank throws or crankpins. More than one piston is attached to the crank to provide a smoother delivery of power to the rotating part, though many small engines such as those found in garden machinery, use only a single piston. The configuration of pistons in relation to each other and the crank and their number leads to descriptions such as straight-4 (four pistons in direct line), V6 or V8. Transmission shafts sizes vary from 10 to 100mm but it can go higher then these figures, the maximum length of shaft usually does not exceed 7m. Propeller shaft Propeller shafts transmit power between the source and the machine, the propeller shaft assembly consists of a propeller shaft, a slip joint, and one or more universal joints. This assembly provides a flexible connection through which power is transmitted from the transmission to the live axle. Axle is similar in shape to the shaft and support bending movements only. The propeller shaft may be solid or tubular. A solid shaft is stronger than a hollow or tubular shaft of the same diameter, but a hollow shaft is stronger than a solid shaft of the same weight. A slip joint is put at one end of the propeller shaft to take care of end play. The driving axle, attached to the springs, is free to move up and down, while the transmission is attached to the frame and cannot move. Couplings A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By using couplings, savings can be made in reduced maintenance costs and downtime. Thompson coupling Thompson coupling is a constant velocity universal joint that can be loaded axially and continue to maintain constant velocity over a range of input and output shaft angles with low friction and vibration. It consists of two cardan joints assembled within each other, so eliminating the intermediate shaft along with a control yoke that geometrically constrains their alignment. The use of cardan joints within the Thompson Coupling is to reduce the wear, heat and friction. The Oldham coupling The Oldham coupling transmits rotary motion between shafts that are parallel but not always in perfect alignment. Oldham couplings consist of three members, a floating member is trapped by 90 displaced grooves between the two outer members which connect to the drive shafts. Oldham couplings can bear lateral shaft misalignments up to 10% of nominal shaft diameters and up to 3 angular misalignments. Clutch: A clutch is a mechanism for transmitting rotation, which can be engaged and disengaged. Clutches are useful in devices that have two rotating shafts. In these devices, one shaft is typically driven by a motor or pulley, and the other shaft drives another device. Friction clutch: it connects two separate pieces of shaft, it also has levers and springs to disengage/engage plates. The primary disadvantage of friction clutches is the regular maintenance and adjustment that are required, mating parts will wear due to friction (resulting in slippage), springs will lose memory, and other parts will need replacement or adjustment. Positive clutch: A clutch designed to transmit torque without slip. It consists of two mating surfaces with interconnecting elements, such as teeth, that lock together during engagement to prevent slipping. Positive clutches are also known as mechanical lockup clutches. Brake: A specific type of clutch that slows and stops motion by engaging a rotating shaft and a fixed component. Disc brake The disc brake or disk brake is a device for slowing or stopping the rotation of a wheel. A brake disc (or rotor in U.S. English), usually made of cast iron or ceramic composites (including carbon, Kevlar and silica), is connected to the wheel and/or the axle. To stop the wheel, friction material in the form of brake pads (mounted on a device called a brake caliper) is forced mechanically, hydraulically, pneumatically or electromagnetically against both sides of the disc. Friction causes the disc and attached wheel to slow or stop. Brakes (both disc and drum) convert friction to heat, but if the brakes get too hot, they will cease to work because they cannot dissipate enough heat. This condition of failure is known as brake fade. Hydraulic brake The hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing ethylene glycol, to transfer pressure from the controlling unit, which is usually near the operator of the vehicle, to the actual brake mechanism, which is usually at or near the wheel of the vehicle. P8 Describe with the aid of diagrams the general layout and operation of a pneumatic actuation system, a hydraulic actuation system and a mechanical handling system Pneumatic autuation system: A pneumatic actuation system is capable of directing an amount of fluid to the contained volume such that a pressure within the contained volume exceeds a pressure external to the contained volume by a predefined positive pressure. With the pressure controller, It can also adjust the pressure within the contained volume when the pressure external to the contained volume changes. The educator can draw fluid from the contained volume to thereby decrease the pressure within the contained volume. The valve is controllably operable in either a pressure mode or a vacuum mode, where the valve either permits the pressure controller to provide fluid to the contained volume, or permits the educator to draw fluid from the contained volume. As such, the system provides precision pressure control over a broad range of external pressures while compensating for rapid pressure changes. Fig. example of pneumatic aculator. Hydraulic actuation system: A hydraulic system for a sterndrive marine propulsion device directs the flow of hydraulic fluid through the body and peripheral components of a gimbal ring in order to reduce the number and length of flexible hydraulic conduits necessary to conduct pressurized hydraulic fluid from a pump to one or more hydraulic cylinders used to control the trim or tilt of a marine drive unit relative to a gimbal housing. Mechanical handling system: Mechanical handling is simply a row of roller/cylindrical or triangle cross-sectional component. They are mostly covered by a long belt but it is not necessary. The rollers or what ever it is used are rotating and the product/component will be moving along and the other rollers will pull it along like the image is shown below. The component/product will move until it reaches its destination or the end of the roller P9 Describe with the aid of diagrams the general layout and operation of a steam power generation plant, a refrigeration system and an air conditioning system. refrigeration system BASIC REFRIGERATION PRINCIPLES If you were to place a hot cup of coffee on a table and leave it for a while, the heat in the coffee would be transferred to the materials in contact with the coffee, i.e. the cup, the table and the surrounding air. As the heat is transferred, the coffee in time cools. Using the same principle, refrigeration works by removing heat from a product and transferring that heat to the outside air. REFRIGERATION SYSTEM COMPONENTS There are five basic components of a refrigeration system, these are: Evaporator Compressor Condenser Expansion Valve Refrigerant; to conduct the heat from the product In order for the refrigeration cycle to operate successfully each component must be present within the refrigeration system. The Evaporator The purpose of the evaporator is to remove unwanted heat from the product, via the liquid refrigerant. The liquid refrigerant contained within the evaporator is boiling at a low-pressure. The level of this pressure is determined by two factors: The rate at which the heat is absorbed from the product to the liquid refrigerant in the evaporator The rate at which the low-pressure vapour is removed from the evaporator by the compressor To enable the transfer of heat, the temperature of the liquid refrigerant must be lower than the temperature of the product being cooled. Once transferred, the liquid refrigerant is drawn from the evaporator by the compressor via the suction line. When leaving the evaporator coil the liquid refrigerant is in vapour form. The Compressor The purpose of the compressor is to draw the low-temperature, low-pressure vapour from the evaporator via the suction line. Once drawn, the vapour is compressed. When vapour is compressed it rises in temperature. Therefore, the compressor transforms the vapour from a low-temperature vapour to a high-temperature vapour, in turn increasing the pressure. The vapour is then released from the compressor in to the discharge line. The Condenser The purpose of the condenser is to extract heat from the refrigerant to the outside air. The condenser is usually installed on the reinforced roof of the building, which enables the transfer of heat. Fans mounted above the condenser unit are used to draw air through the condenser coils.The temperature of the high-pressure vapour determines the temperature at which the condensation begins. As heat has to flow from the condenser to the air, the condensation temperature must be higher than that of the air; usually between 12Â °C and -1Â °C. The high-pressure vapour within the condenser is then cooled to the point where it becomes a liquid refrigerant once more, whilst retaining some heat. The liquid refrigerant then flows from the condenser in to the liquid line. The Expansion Valve Within the refrigeration system, the expansion valve is located at the end of the liquid line, before the evaporator. The high-pressure liquid reaches the expansion valve, having come from the condenser. The valve then reduces the pressure of the refrigerant as it passes through the orifice, which is located inside the valve. On reducing the pressure, the temperature of the refrigerant also decreases to a level below the surrounding air. This low-pressure, low-temperature liquid is then pumped in to the evaporator M1) . Compare and contrast the operation and uses of flat plate clutches, centrifugal clutches and fluid couplings in mechanical power transmission systems flat plate clutches centrifugal clutches fluid couplings The fluid coupling is operated simply by a hydraulic fluid and the driver bladed wheel. The driver wheel rotates and rotates the fluid in between follows it along and cause the driven bladed wheel to rotate along the hydraulic fluid. The hydraulic and driven bladed wheel are still under motion even if the driver bladed wheel stops. The friction disc is sandwiched between the machined surfaces of the flywheel and the pressure plate when the pressure plate is bolted to the outer edge of the flywheel face. The clamping force on the friction facings is provided by the diaphragm spring. Unloaded, it is a dished shape. As the pressure plate cover tightens, it pivots on its fulcrum rings, and flattens out to exert a force on the pressure plate, and the facings. It is used in gears, turbine and many more. A clutch operated by centrifugal force from the speed of rotation of a shaft, as when heavy expanding friction shoes act on the internal surface of a rim clutch, or a flyball-type mechanism is used to activate clutching surfaces on cones and disks. Weights wherein each weight has an arc-shaped clutch shoe and is pivotally mounted with a lever foot on a carrier disc on the drive end of the clutch. After reaching a specific rpm, the clutch shoes are pressed under the action of centrifugal force against the inner wall surface of a clutch drum for providing friction-tight torque transmission. The clutch drum surrounds the clutch shoes. The centrifugal clutch includes a carrier disc on which the centrifugal weights are pivotally mounted. A cover disc is held axially tight at the sides of the centrifugal weights which lie opposite the carrier disc. This cover disc radially covers the clutch shoes so that axial guide play is provided. It is used in generators. Device used to transmit rotating mechanical power. It has been used in automobile transmissions as an alternative to a mechanical clutch. There is no mechanical interconnection between the impeller and the rotor (i.e. the driving and driven units) and the power is transmitted by virtue of the fluid filled in the coupling. The impeller when rotated by the prime mover imparts velocity and energy to the fluid, which is converted into mechanical energy in the rotor thus rotating it. It is used n aviation, engineering companies and many more. M2) Compare and contrast the operation and use of pneumatic and hydraulic actuation systems Pneumatic autuation system: A pneumatic actuation system is capable of directing an amount of fluid to the contained volume such that a pressure within the contained volume exceeds a pressure external to the contained volume by a predefined positive pressure. With the pressure controller, It can also adjust the pressure within the contained volume when the pressure external to the contained volume changes. The educator can draw fluid from the contained volume to thereby decrease the pressure within the contained volume. The valve is controllably operable in either a pressure mode or a vacuum mode, where the valve either permits the pressure controller to provide fluid to the contained volume, or permits the educator to draw fluid from the contained volume. As such, the system provides precision pressure control over a broad range of external pressures while compensating for rapid pressure changes. pneumatic actuator system provides the advantage of lower weight and more economical construction. One distinct adv antage of a pneumatic system is that it may utilize a source of bottled gas or the like as a potential energypower source. Fig. example of pneumatic aculator. Hydraulic actuation system: A hydraulic system for a sterndrive marine propulsion device directs the flow of hydraulic fluid through the body and peripheral components of a gimbal ring in order to reduce the number and length of flexible hydraulic conduits necessary to conduct pressurized hydraulic fluid from a pump to one or more hydraulic cylinders used to control the trim or tilt of a marine drive unit relative to a gimbal housing. advantages of pneumatic acutators over hydruallic actuators Relatively cheaper. The force transmitter, air, is freely available. Cleaner system as air leakage do not create a mess. Hydraulic oil becomes very hot after continuous use. Can cause injury if someone comes in contact. Generally have open circuits and we dont have to worry about the return circuit. Justify the use of Shell Tellus oil 27 lubricant and the splash lubrication system in the lathe machines in the College machine shop. Shell Tellus Oils oil 27 are premium quality hydraulic oils generally acknowledged to be the standard-setter in the field of engineering hydraulic and fluid power lubrication. The Shell Tellus oil 27 lubricants are mineral oils.It has an active anti-corrosion additive effectively protects hydraulic systems from corrosion. Water collects in the lubrication system due to condensation with soluble cutting fluid and is emulsified to provide further protection. It has excellent anti wear which means that lathe machine can be used for longer unlike other lubricants, it also helps improve the efficiency of filtration systems to reach system cleanliness targets.The dirt can also clean easily off. The lubricant provides anti-war and increase the resistance of the lathe material surface. It also helps to operate under high temperature; actually it works as a coolant. The lubricant also does a quick air release without excessive foaming. Other point is that the lubricant has very low environmental impact because of the zinc free technology. It also doesnt react with other chemical when it is in use. Shell tellus oil 27 has high lubrication properties and excellent low friction characteristics in hydraulic systems operating at low or high speed. Prevents stick-slip problems in critical applications enabling very fine control of machinery.
