Why the Range of Indicators Used to Measure Development...

Why the Range of Indicators Used to Measure Development Has Increased in Recent Years Essentially the ideology of development was based on a countries GNP this was down to Rostow’s Model; therefore the only indicator of development was a countries economy. The ideologies have changed and now there are a range of indicators that are used to classify a countries development such as social, demographic, hence including quality of life this gives the ideology of development a more multi dimensional view thus a better understand of what a developed country is. There are three categories that are used to measure development they are economic, social and demographic. Some economic factors used to†¦show more content†¦Other limitations in using GNP is that it needs to measure by a currency and with currencies always changing figures can become less accurate. Also in LEDC’s figures are less accurate and a lot of business is done within the informal sector thus leaving GNP figures very unreliable. It also does not take into account the cost of living is different depending on countries for example 10 dollars in and LEDC will buy a person a lot more than what it would buy you in America. GNP’s frequent use suggest that development is only based on a countries wealth, where as this not true because development is multi dimensional process. The other economic factors such as better transport link and energy consumption tie in well with GNP and make using a countries economy more useful in considering if a country is devel oped or not. Some social indictors of development include the adult literacy rate, incidence of doctors and access to a clean water supply. Adult literacy rates are good measure of development because it shows the countries population who have access to education, with people able to communicate in other ways rather than word of mouth enhances the chance of employment. Also one can compare the literacy rates between male and female if they are more men able to read and write it suggest that women do noShow MoreRelatedThe Federal Open Market Committee1571 Words   |  7 Pagesand contribute to the assessment of the policy options and economy.

Conflict in Nathaniel Hawthornes the Scarlet Letter Essay

Conflict in Nathaniel Hawthorne’s The Scarlet Letter Conflict can take on many forms in one’s life, such as conflict with self, with society, with religion and with others. Nathaniel Hawthorne’s The Scarlet Letter, develops the theme of conflict through the moral sin of Hester Prynne. Conflict is observed through Hester’s difficulties with the townspeople, challenges with the Puritan way of life, struggles with herself and tensions with Roger Chillingworth. Committing sin in the Puritan society leads to a great deal of conflicts. Conflict is first observed through Hester’s ongoing difficulties with her fellow townspeople. Hester receives ridicule from on looking townspeople, as a gossiping woman states, ‘ â€Å"At the very least, they†¦show more content†¦Hester faces conflict with Puritan society again when she cannot use her elaborate seamstress skills to make bride veils. Although Hester is very talented she is restricted from a nything that would offend the Puritan society, which becomes evident when it is stated, â€Å"But it is not recorded that, in a single instance, her skill was called in aid to embroider the white veil which was to cover the pure blushes of a bride† (73). The moral sin of Hester Prynne leads to conflict with the Puritan way of life. Hester continues to face conflict, this time with herself. When Hester faces the reality of the unpleasant situation she is faced with, her self conflict begins. Hester’s feelings are expressed when it is stated, â€Å"She clutched the child so fiercely to her breast that it sent forth a cry; she turned her eyes downward at the scarlet letter, and even touched it with her finger, to assure herself the infant and the shame were real† (52). Conflict within Hester’s life continues in mothering her curious child. Pearl’s curiosity is revealed when she asks, ‘ â€Å". . . Mother dear, what does this scarlet letter m ean? –and why dost thou wear it on thy bosom?† ’ (161). Hester feels the responsibility of protecting Pearl from knowing her mother’s sinful actions.

The Hunters Phantom Chapter 17 Free Essays

Once he got outside, Stefan remembered that Elena had taken his car. Turning into the woods, he began to run, using his Power to speed his pace. The pounding of his feet seemed to thud, Guard her, Guard her. We will write a custom essay sample on The Hunters: Phantom Chapter 17 or any similar topic only for you Order Now He knew where Tyler Smal wood had lived. After Tyler had attacked Elena at a dance, it had made sense to keep an eye on him. Stefan burst from the woods at the edge of the Smal woods’ property. They owned an ugly house, in Stefan’s opinion. An inaccurate portrayal of an old Southern manor estate, it was too big for the lawn it sat on and bulged with unnecessary columns and twisting rococo decorations. Just looking at it, Stefan had been able to tel that the Smal woods had more money than taste, and that the architects who’d designed it weren’t educated in true classical forms. He rang the bel at the front door, then froze. What if Mr. or Mrs. Smal wood answered the bel ? He would have to Influence them to give him as much information as they could about Caleb, and then to forget Stefan had been there. He hoped he had the Power to do it: He hadn’t been eating enough, not even of animal blood. But no one came. After a few seconds, Stefan sent questing tendrils of Power through the house. It was empty. He couldn’t go in, couldn’t search Caleb’s room like he wanted to. Without an invitation, he was stuck out here. He wandered around the house, peering through the windows, but finding nothing out of the ordinary other than entirely too many gilded frames and mirrors. Behind the house he found a smal white shed. Sending Power toward it, he felt something slightly†¦ off. Just the slightest tinge of darkness, a feeling of frustration and il intent. The shed was padlocked, but the lock was easy enough to snap. And as no one lived here, he didn’t need an invitation to enter. The first thing he saw was Elena’s face. Newspaper clippings and photos were tacked al over the wal s: Elena, Bonnie, Meredith, himself. On the floor was a pentagram with more pictures and roses. Stefan’s certainty that something was wrong solidified. Elena was in danger. Sending Power before him, searching desperately for any trace of her, he took off running again. As she drove away from the florist’s, Elena turned the conversation with Stefan over and over in her mind. What was going on with him since they’d come back to Fel ‘s Church? It felt like there was part of him that he was holding back, hiding from her. She remembered the loneliness, the sinking, dizzy feeling of isolation that she had sensed when she kissed him. Was it Damon’s loss that was changing Stefan? Damon. Just the thought of him was enough to cause an almost physical pain in her. Mercurial, difficult, beautiful Damon. Dangerous. Loving, in his own way. The thought of his name, written in water plants across Meredith’s legs, floated through her mind. She didn’t know what it meant. But there was no hope. She needed to stop lying to herself about that. She had seen Damon die. Yet it seemed impossible that someone as complex and strong and seemingly undefeatable as Damon could be gone so quickly and so simply. But that was the way it happened, wasn’t it? She should know that death didn’t often come with a grand show, that it usual y came when you were least expecting it. She had known that before al this†¦ al this stuff with vampires and werewolves and evil mysterious opponents. She had known al about the suddenness and simplicity of death for years, back when she was just normal Elena Gilbert, who didn’t believe in anything supernatural, not even horoscopes or fortune-tel ing, much less monsters. She glanced at the passenger seat next to her, where there lay the bouquet of pink roses she had picked up to give to Margaret. And, next to them, a simple bunch of forget-me-nots. Like I’d ever forget, she thought. Elena remembered riding in the car toward home with her parents and baby Margaret on an ordinary Sunday afternoon. It had been a beautiful sunny fal day, the leaves of the trees by the roadside just beginning to be painted with red and gold. They’d gone to lunch at a little inn out in the country. Margaret, who was teething, had been cranky at the restaurant, and they’d taken turns walking her up and down on the porch of the inn for a few minutes at a time while the others ate. But in the car she was quiet, half drowsing, her light golden lashes fluttering down to rest for longer and longer periods against her cheeks. Elena’s father had been driving, she remembered, and the radio had been tuned to the local station so he could catch the news. Her mother had twisted to look at Elena in the backseat, her sapphire blue eyes so like Elena’s own. Her golden hair, touched with a little gray, was pul ed back in a French braid, elegant and practical. Smiling, she had said, â€Å"Do you know what I think would be nice?† â€Å"What?† asked Elena, smiling back at her. Then she saw a strange glitter, high in the sky, and leaned forward without waiting for a reply. â€Å"Daddy, what’s that?† She’d pointed upward. Elena never found out what her mother had thought would be nice. Her father never answered what that was. The last things Elena remembered were sounds: her father’s gasp and the screech of the car’s tires. Everything after that was blank, until Elena had woken up in the hospital, Aunt Judith by her bedside, and learned that her parents were dead. They had died before the paramedics had even pried them out of the car. Before they restored Fel ‘s Church, the Guardians had told Elena that she should have died in that accident, and that her parents should have lived. The glitter had been their air car, and Elena had distracted her father at the worst possible moment, causing al the wrong people to die. She could feel the weight of it now, the guilt at surviving, her anger at the Guardians. She glanced at the dashboard clock. There was stil plenty of time before she had to be at Margaret’s recital. Turning off the highway, she pul ed into the cemetery’s parking lot. Elena parked the car and walked briskly through the newer part of the cemetery, carrying the forget-me-nots. Birds were chirping gaily overhead. So much had happened in this cemetery in the last year. Bonnie had seen one of her first visions among these tombstones. Stefan had fol owed her here, watching her secretly when she thought he was just the gorgeous new guy at school. Damon had nearly drained an old tramp under the bridge. Katherine had chased Elena out of the cemetery with fog and ice and a far-reaching, far-seeing evil. And, of course, Elena had driven off a bridge to her death here by the cemetery, at the end of that first life, the one that seemed so long ago now. Elena picked her way past an ornate marble memorial to Fel ‘s Church’s Civil War veterans and down to the shady glen where her parents were buried. The tiny wildflower bouquet she and Stefan had left two days before had withered, and Elena threw it away and put the forget-menots in its place. She picked a bit of moss off her father’s name. The lightest crunch of gravel sounded from the path behind her, and Elena whirled around. There was no one there. â€Å"I’m just jumpy,† she muttered to herself. Her voice sounded oddly loud in the quiet of the cemetery. â€Å"Nothing to worry about,† she said more firmly. She settled in the grass by her parents’ graves and traced the letters on her mother’s headstone with one hand. â€Å"Hi,† she said. â€Å"It’s been a while since I’ve actual y sat here and talked to you, I know. I’m sorry. An awful lot has happened†¦Ã¢â‚¬  She swal owed. â€Å"I’m sorry, too, because I found out that you weren’t supposed to die when you did. I asked the Guardians to†¦ to bring you back, but they said you had moved on to a better place and they couldn’t reverse that. I wish†¦ I’m glad you’re happy wherever you are, but I stil miss you.† Elena sighed, lowered her hand from the gravestone, and trailed it through the grass by her knees. â€Å"Something’s after me again,† she continued unhappily. â€Å"After al of us, I guess, but Bonnie said I brought it here when she was in a trance. And later she said he wants me. I don’t know if it’s two different people – or whatever – after us, or just one. But it’s always me the bad things focus on.† She twisted a blade of grass between her fingers. â€Å"I wish things could be simpler for me, the way they are for other girls. â€Å"Sometimes†¦ I’m so glad to have Stefan, and glad I could help protect Fel ‘s Church, but†¦ it’s hard. It’s real y hard.† A sob was building in her throat and she swal owed it back. â€Å"And†¦ Stefan’s always been there for me, but I feel like I don’t know al of him anymore, especial y because I can’t read his thoughts. He’s so tense, and it’s like he needs to be in control al the time†¦Ã¢â‚¬  Something shifted behind her, just the slightest hint of movement. She felt a warm, damp breeze like a breath on the back of her neck. Elena whipped her head around. Caleb was crouching behind her, so close they were almost nose-to-nose. She screamed, but Caleb slapped his hand over her mouth, muffling her cry. How to cite The Hunters: Phantom Chapter 17, Essay examples

Building Regulation Studies

Question: Discuss about theBuilding Regulation Studies. Answer: Overall Efficiency: In order to get Overall efficiency for the sole occupancy unit, it is necessary to get a rating more than six stars. There are a number of units of Class 2 or the Class 4 building and it must include; Approaches to reduce the heating or cooling of loads- The average rating shall not be less than 6 stars, Individually, shall not achieve an energy rating of not less than 5 stars. The House energy software can be used for rating. This rating shall be based on other holistic approach that might include items like glazing and other electrical systems. The benefit of using the glazing on the exterior wall is to create a frosted appearance that in turn reduces the amount of incoming radiation of the harmful UV rays that would have otherwise penetrated in the building. Another benefit of the same is that glazed glasses also reduce the amount of air-conditioning and lighting that is indeed required for the overall development. In this respect, the calculation of glazing formula can be stated here: [(A1 x U1) + (A2 x U2) + .......] / [(A1 x SHGC1 x EW1) + (A2 x SHGC2 x EW2) + ........ ] When the values are known, the adequacy of compliance can be checked easily. In this respect, it has to be mentioned that without proper values the compliance cannot be determined effectively. The dwelling also needs an integrated air conditioning system to be employed. In Volume 2, Part 3.12.3, it is been observed that there should be potential ways to reduce air leakage from the different parts like ceiling, roof, floors and even walls. Since, it is equipped with self-closing doors there is a less chance of air leakage for all the public entrances and verandah. In Part of Volume 1 PJ3, it shows the necessity of sealing the doors and windows in order to guard the flow of air. It has been recommended that for better functioning of the air conditioner, blocking the doors and windows is important to ensure that there is minimum loss of energy. The detail of the plan of the entire building has to be known to understand any kind of deficiency that the building is suffering from. The overall deficiency has to be recognized both in terms of its exterior and its faade. When necessary arrangements are made, it reduces the impact of exterior heat or cold of the building. There shall be provision for reducing the dependency of the air conditioning system or any other kind of ventilation. It can be said that the development of the Grose Road development is to be constructed of alucobond clad walls, with certain distinct sections that can be either rendered or stone finished. As known, alucobond is a light weight building material that reduces the heating and the cooling effect on the building. AS3959 compliance has stated that Alucobond is a certified CodeMark for fire compliance that protects bushfire attack and general living conditions. Therefore, the exterior of the building shall be made with the proposed business standard to ensure maximum safety for the building. If the re-using of the construction materials is considered, it is evident that there are certain overall deficiencies in terms of the overall plan of the construction of the building. The On-site detention facility that has the provision for holding at least 55 cubic meter of water at a particular time is one of efficient equipment that the building has. The water that is stored here comes from the roof and from other places like car parking. The same unused water can be used for watering the plants in case if there is heavy rain or for other secondary purposes like laundry or the toilet. It has to be noted that there is an insufficient details of the efficiency of the appliances particularly in the kitchen. It has to be mentioned in this respect that in order to achieve an overall efficiency, clarification should be made by Building Code of Australia consultant and other complains due to insufficient data about the building plan. It has been observed that there is a lack of independence on the building plan. The buildings have a high dependency on the energy grid being efficient to understand how it is used. The plan is to deficient the BASIX things like that of the solar panels or water storage. These processes help to contribute in building independence by limiting the energy usage. Building Fabric: It has been stated in the NCC Volume Two, Part 3.12.1 that thermal resistance is recognized by a considerable R value. This value depends on certain factors like the building zone, like the Zone 6 and other types of buildings, taught in Class 2 of the report. It has been known that the fabric used for the building is R3.0 with insulation, alucobond and timber framed roofing. It has compliance with the J1.2 NCC building specification. On the ground floor, the internal and the external walls also comply with the NCC building specification. It has to be understood that there should be a compliance with NCC though there is a concrete slab-on ground floor. Climate Zone Options 4 and 6 Compliance with the external glazing factors as mentioned in 3.12.2.1 along with the application of Cu as mentioned in Table 3.12.2.1 has been reduced by 15% and Insulation in the external wall that incorporates with the R value has not less than 0.5; and lastly, The habitable room at the lowest storey has the following : The floor is concrete Masonry internal walls Compiling with 3.12.2.1 with certain applicable values for Cu mentioned in Table 3.12.2.1 has been reduced by 20%.- The external wall has the power of insulation with an R-value that is not less than 1.0, lastly, The habitable rooms at the lowest storey contains, Ground floor with concrete slabs Masonry internal walls There is the presence of R3 insulation within the building plan. In the NNC Volume 1 J 1.2 and AS/NZS 4859.1 Standards, the insulation materials have been prescribed. In NCC Volume One J1.2 installation instruction has been mentioned. The plan is inclusive of: It overlaps with the adjoining insulation other than supporting the other members like studs, furring channels, joists, noggin and other likable channels where the process of insulation must be against the members There has been a continuous barier with the different parts of the rooms like ceiling, walls, bulkheads or the floors. These factors are likely to create a barrier to the thermal condition of the room. It does not create any negative impact on the safety and effectiveness of the operation of service fitting. It has been further specified that a building with: A wall in Table 3.12.1.3a that- i) it is supported with light weight cladding like the weatherboards, fiber cement or other metal sheets fixed to the metal frame. There must be a wall lining that is directly fixed with the metal frame of the door or window There must be a thermal break that consists of the material R It can be easily said that using the specification mentioned above, the external walls can easily comply with the current business standards. The Alucobond cladding used as the fabric for external building material produces a pleasing appearance. It is used to keep the warmth out in warmer countries Cold does not penetrate into the interior It is completely weather resistant -Internationally approved fire performance (Alucobond, 2016) Another important factor of Alucobond is its ability of fire resistance. The Building Code of Australia with the Code Mark Certification of the product for fire compliance, with the business standards and Volume One and Two of the National Construction code. Therefore, ir automatically creates a confidence and certainty to the regulatory authorities and other market issues. The Certificate of Conformity provides an appropriate certification of the complete bush prone areas. It is not the exterior makeup but the interior makeup of the construction as well that requires a fire compliance. The interior wall including the load bearing has the timbre frame. Services and Lighting: Another deficiency of compliance or the deficiency is related to the air conditioning or the ventilation system. In multiple units, the air conditioning system must be controlled by each unit according to the requirement of the building. In Volume 1 Part J5, it has been said that the various methods of using the air conditioning exceeds 10 Kw in the commercial context. The artificial lighting also complies with the Sole-Occupancy Unit. The code Volume 1 Part J6 specifies the power density of illumination. The measurement of the illumination is measured in W/m2. This can be signified as below: Car park: 6 Entry lobby: 15 Kitchen: 8 Retail space: 25 Service area: 3 Volume 1, J 6.2 in the NCC states that the maximum power of illumination for the artificial light must not exceed 5W/m2 within the occupancy of the unit of 4 W/m2 on places like balconies. There arises a gap in the specificity of the requirement through some unknown placement and certain volume of lighting with their respective power outputs and other sources due to lack of proper information. Certain excerpts states that the controlling should be rest to the one who are at the individual rooms. Using the correct intensity of light shall remain on the choice of the one who is present at the particular room. Another example can be made here is related to the car parking. The users can be given a remote control device to operate the lights. In case of the kitchen, there shall be presence of both gas and electricity. There are evidences regarding the building plan that most of the appliances are related to gas equipment. In case, if the compliant is breached there shall be compliance with the gas powered equipment. In case of any breaching, the homeowners or the occupiers and other service personnel might be told to use appropriate resources to reduce the impact of environmental energy impact in buildings.

Moreover, it also focuses at creating values for scientific excellence and generate leadership in order to eradicate public health hazards and threats (Wright Harwood, 2012). The public Health Agency of Canada helps the minister to perform their respective responsibilities, functions and duties honestly and exercise their powers with the relation to public health. Only after delivering the legislative and regulative programs, this agency is also looking to comply with the Cabinet Directive on Regulatory Management (Hoek Jones, 2011). Role of Public Health Regulations Public Health Agency of Canada aims at following the given responsibilities which are mentioned below. List of Rules, Acts and Regulations Managing the burden of administrative baseline Regulating forward plan among its members Providing service standards for high volume regulatory authorizations Introducing interpretation policies Taking departmental actions and respond directly to the Red Tape Reduction Commissions Recommendations Report Public interest theory of regulation This is the first group of regulation which aims at the public interest. It can be defined as one of the best possible allocation of resources which are scarce in nature. It allocate those resources to specific individual or collective goods. For an instance, in many western economies, the allocation is done by using market mechanism. According to this theory, resources are allocated by using market mechanism which is very optimal which tends to increase the demand to improve those scarce resources. Government regulations plays an important role in the efficient allocation of the resources. Government regulation is a tool which is used to overcome the disadvantages of competition which are imperfect in nature, eradicate the unbalanced operations, and meet unfavorable market results. These regulations helps in facilitating, maintaining and improving all the market operations in an effective way. Moreover, the cost that is involved in the transaction of the market operations are decreased by implementation of laws. For example if every business will start producing the same quantity of goods then it will automatically rise the unit costs of production and it will be very difficult to rise modest marginal cost. Therefore, monopolist strategy must be used to increase profits and set a fixed price (Baldwin, Cave Lodge, 2012). Information Problems Public Interest theory states that there is no restrictions to any imperfect competition and market operations. Sometimes, it may happen that the market may not have sufficient goods but the customer is willing to pay the cost. Thus, it creates information problems. In such cases, the regulations aims at improving the efficiency of the economy. All the missing elements must be addressed properly. All the problems must be identified and resolved under some certain circumstances. If the problem is related to health issues, then it must identify the major reasons behind it and the ways to eradicate those problems as well. When these problems will be identified then, it will reduce the unnecessary costs and the risk involved in it (Hantke, 2003). The major concerns of this theory Sometimes, it becomes very difficult to decide the actual amount of regulations with the complex commodity like information and then convince everyone to get involved in it. The other problem is the motivation of the regulatory body. It is very difficult to act in their own interest rather than acting as public interest. Private interest theory of regulation This theory of regulation state that regulations comes with the passage of time. Legislators subject any industry only with the help of agency. All the activities of the regulatory agency is monitored unless other political priorities takes place on the agenda. The agency will aim to remove conflicts because it will be totally dependent on the company to get all the information. The company often have limited number of resources which helps them to be aware of the cost involved in it. Moreover in such regulatory companies, huge number of opportunities are generated which helps to create career options available to its members. Sometimes it becomes very difficult to identify the interest of the company and know whether it will succeed or not. This theory of regulation often express that regulations takes place in the favor of the industry instead of the interest of consumers. Some companies feel obliged to enhance their services and get involved in providing voluntary services (Schiav o, 2013). Similarly, private theory basically focuses on the hypothesis instead of focusing in the theoretical implications. It never gets involved in giving an explanation of why a company is able to take over regulatory agency. It also does not explain the reason behind why an interaction between the firm and the agency takes place (Hertog, 2010). Introduction of Dynamic Capture theories This theory is developed in recent days which helps to explain the life cycle of the regulatory agencies that takes place over time. It helps the public interest to act more efficient and helps private interest to please their potential customers to get involved in it. Capture theories helps to improve power of the agency. An agency must know a company better and maintain a strong ongoing relationships. The agency are the one who has several opportunities to follow objectives that set political principles which can only be controlled by the fair rule and regulations (Faludi, 2013). Thus, it can be concluded that public health regulations plays an important role in a country to improve the health of the people. It also aims at reducing the health related hazardous problems by providing proper guidelines and support systems. The two major theories of regulations i.e. public interest theory and private interest theory better explains the several factors that is involved within the company and outside the company along with the role of the agency.

How to Reduce Accidents free essay sample

They demonstrate a central tendency which should not rule out a range of differences within each concept. ) 1. Assertiveness:   U. S. Americans tend to be candid and outspoken in communication with others, and they seldom shy away from disclosing facts about themselves. They prefer direct questions and respond with straight answers. They employ face-to-face confrontations to resolve differences. These patterns of behavior sometimes lead people from other cultures to view U. S. Americans as overly aggressive. 2. Effort-Optimism:   The linking of effort with optimism is one of the central characteristics of U. S. thought. Effort-optimism is a denial of fatalism;   it is the assumption that any challenge can be met, any goal achieved, if only a sufficient quantity of time, energy, skill, and willpower are applied. The motto of the U. S. Navys Construction Battalions (See-Bees) during World War II exemplifies this concept:   The difficult we do immediately;   the impossible takes a little longer. We will write a custom essay sample on How to Reduce Accidents or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page 3. Friendliness:   U. S. friendships is typified by warmth, informality, and other signs of acceptance, even toward comparative strangers. On the other hand, U. S. Americans assume that friendship involves comparatively few mutual obligations and lasts a relatively short time. People from other cultures become confused because those whom they would consider mere acquaintances are called friends by U. S. Americans, and because the warm manner of U. S. Americans leads them to expect a degree of commitment that the U. S. Americans do not feel and would find difficult to accept. 4. Getting Things Done:   U. S. Americans are most content when they are doing something. They believe that hard work is intrinsically valuable. In judging others, they give the most weight to their achievements, much less to character or spiritual qualities. U. S. Americans strive for efficiency because it enables them to get more things done in a given period of time. To people from certain other cultures, however, U. S. Americans seem driven. 5. Individualism:   The concept of individualism stresses the separateness of one human being from another, and the responsibility and initiative that each person must take on his own behalf. U. S. Americans join and leave groups frequently according to changing personal needs. people from highly group-centered cultures find the U. S. way of life fragmented because of its focus on individuals. 6. Materialism:   Like most other peoples, U. S. Americans are concerned about their well-being;   the difference in some cases is that U. S. Americans measure their well-being in terms of the number of tangible things at their command that enable them to enjoy uninterrupted comfort and convenience. People from cultures where spiritual, intellectual, or personal qualities are most highly valued may be so dazzled by U. S. Americans materialism that they overlook their finer values. 7. Pragmatism:   U. S. Americans are deeply practical. They want things, procedures, and people to meet the requirements of actual use in daily life. They tend to be adaptable and realistic, and they rely on common sense.    In making judgments, U. S. Americans are most interested in whether something works. Other peoples around the world often give more weight to historical tradition, theological command, moral purity, or theoretical consistency. 8. Progress:   U. S. Americans are oriented toward the future;   they want it to be better than their past and present. Given their elentless pursuit of happiness, they believe not only that thi ngs and people can be made to improve, but also that they should be made to improve. 9. Puritanism:   Puritanism is the term that describes the U. S. American habit of seeing a cause-effect relationship between correct thinking and good behavior on the one hand, and material reward or successful outcome on the other. It arose out of the old Calvinist doctrine that prosperity and success were sure signs that an individual was in Gods favor. 10. Scientific Method:   The methods of science involve devotion to attitudes such as skepticism, empiricism, and rationalism, and to procedures such as experimentation, detailed analysis, and inductive reasoning (reasoning from established facts to tentative conclusions). U. S. Americans seem to have a built-in readiness to accept scientific explanations as far more likely than any other possible explanation. Other peoples often remain at least as likely to rely on mysticism, authority, or tradition. 11. Success:   The self-esteem of individual U. S. Americans is largely tied   to their ability to get ahead in terms of the recognition of their peers as well as material affluence and social mobility. There is a deeply held belief in the U. S. that   anyone- through hard work, talent, and persistence- can rise well above the station in life to which he or she is born. Many other peoples around the world regard their status and role in life as both permanent and proper, and fail to comprehend the constant upward striving of U. S. Americans. 12. Time Consciousness:   U. S. Americans tend to feel that time is relentlessly rushing past them, and they frequently need to know exactly what time it is. They attempt to save time by moving at a rapid pace, taking shortcuts, and improving their efficiency of operations. They soon become anxious if forced to waste time. U. S. Americans are nearly always punctual and they expect others to be on time, too. Many other peoples have a far more relaxed attitude about time;   some seem to be almost unaware of its passage and in no way share U. S. Americans concern for punctuality. 14. America and the English Tradition| By Harry Morgan Ayres| | | This admirable summary of Anglo-American history first appeared (February, 1920) as an editorial in the Weekly Review. It seemed to me then, and still does, as a model in that form of writing, perfect in lucidity, temperance and good sense. Mr. Ayres is a member of the faculty of Columbia University (Department of English) and also one of the editors of the Weekly Review. Beowulf, Chaucer, Shakespeare and Seneca seem to be his favorite hobbies. | |   Ã‚  To sum up the gist of Anglo-American relations in half a dozen pages, as Mr. Ayres does here, is surely a remarkable achievement. | THE RECENTLY established chair in the history, literature, and institutions of the United States which is to be shared among the several universities of Great Britain, is quite different from the exchange professorships of sometimes unhappy memory. It is not at all the idea to carry over one of our professors each year and indoctrinate him with the true culture at its source. The occupant of the chair will be, if the announced intention is carried out, quite as often British as American, and quite as likely a public man as a professor. The chief object is to bring to England a better knowledge of the United States, and a purpose more laudable can scarcely be imagined. Peace and prosperity will endure in the world in some very precise relation to the extent to which England succeeds in understanding us.   Ã‚  Ã‚  1|   Ã‚  It is not an illusion to suppose that our understanding of the British is on the whole better than theirs of us. The British Empire is a large and comparatively simple fact, now conspicuously before the world for a long time. The United States was, in British eyes, until recently, a comparatively insignificant fact, yet vastly more complicated than they imagined. Each, of course, perfectly knew the faults o f the other, assessed with an unerring cousinly eye. The American bragged in a nasal whine, the Briton patronized in a throaty burble. Whoever among the struggling nations of the world might win, England saw to it that she never lost; your Yankee was content with the more ignoble triumphs of merchandising, willing to cheapen life if he could only add to his dollars. But the excellence of English political institutions and methods, the charm of English life, the tremendous power of the Empire for promoting freedom and civilization in the world, these are things which Americans have long recognized and in a way understood. Anything like an equivalent British appreciation of America in the large seems confined to a very few honorable exceptions among them. Admiration for Niagara, which is half British anyway, or enthusiasm for the â€Å"Wild West†Ã¢â‚¬â€your better-class Englishman always thrills to the frontier—is no step at all toward rightly appreciating America. |   Ã‚  Ã‚  2|   Ã‚  To no inconsiderable extent this is America’s own fault. She does not present to the world a record that is easily read. It is obvious, for instance—and so obvious that it is not often enough stated—that America has and will continue to have a fundamentally English civilization. English law is the basis of her law. English speech is her speech, and if with a difference, it is a difference that the philologist, all things considered, finds amazingly small. English literature is her literature—Chaucer and Shakespeare hers because her blood then coursed indistinguishably through the English heart they knew so well; Milton, Dryden, and the Queen Anne men hers, because she was still a part of England; the later men hers by virtue of affectionate acquaintanceship and a generous and not inconsiderable rivalry. English history, in short, is her history. The struggles of the thirteenth century through which law and parliament came into being, the struggles of the seventeenth century through which law and parliament came to rule, are America’s struggles upon which she can look back with the satisfaction that some things that have been done in the world need never be undone or done over again, whatever the room for improvement may still be. Americans, no less than British, recognize that independence was largely an accidental result of a war which sprang out of a false theory of economics, but whose conclusion carried with it a lesson in the management of empire which subsequent history shows the British to have learned thoroughly and for the benefit of all concerned. American independence, however, once established, pointed a way to democratic freedom which England hastened to follow. This we know. And yet—|   Ã‚  Ã‚  3|   Ã‚  And yet we allow these obvious and fundamental considerations to become marvelously obscured. We allow England’s failure to solve an insoluble Irish problem to arouse in us an attitude of mind possibly excusable in some Irishmen, but wholly inexcusable in any American. We allow a sentimental regard for some immigrant from Eastern Europe, who comes to us with a philosophy born of conditions that in English-speaking lands ceased to be centuries ago, to make us pretend to see in him the true expression of America’s traditional ideals. We allow ourselves to be far too easy with the phrase, â€Å"He is not pro-German, he is merely anti-British. Why are they anti-British? Why should they be permitted to make it falsely appear that recognition of the English basis of America involves approval of everything that England in her history may or may not have done? Why should they be allowed to pretend that disapproval of some particular act of England justifies repudiation of most of the things by virtue of which we are what we are? America from the first has been part of the great English experiment—great because it is capable of learning from experience.   Ã‚  Ã‚  4|   Ã‚  The world has put a big investment in blood and treasure, and all that they imply, into the education of England. It is satisfied—the world’s response to Geermany’ insolent challenge is the proof of it—that its pains have been well bestowed. England is more nearly fit than any other nation to wield the power that is hers. That is not to deny the peculiar virtues of other nations; indeed, these virtues have largely contributed to the result. Italy has educated her; France has educated her; we have done something; and Germany. In result, she is not perfect—the English would perhaps least of all assert that—but she has learned a great deal and held herself steady while she learned it. It is a bigger job than the world cares to undertake to teach any other nation so much. Nor would it be at all likely to succeed so well. For what England has to offer the world in return is not simply her institutions; it is not merely a formula for the effective discharge of police duty throughout the world; it is the English freeman, whether he hail from Canada, Australia, Africa, or the uttermost isles of the sea.   Ã‚  Ã‚  5|   Ã‚  A most adaptable fellow, this freeman, doing all sorts of work everywhere, and with tremendous powers of assimilation. Consider him in his origins. He began by assimilating fully his own weight in Danes, while remaining an English freeman. He then perforce accepted a Norman King, as he had accepted a Danish one, hoping, as always, that the kind would not trouble him too much. But when Norman William, who was very ill-informed about the breed, killed off most of his natural leaders and harried the rest into villainy, how did he manage in a small matter of two hundred years or so to make an English gentleman not only of himself but of all the rag-tag of adventurers who had come over with William and since? How did he contrive, out of a band of exiles fleeing from an Egypt of ecclesiastical tyranny, broken younger sons, artisans out of a job, speculators, bondmen, Swedes, Dutchmen, and what not, to make America? Is he one likely to lose his bearings when in his America the age-old problem again heaves in view? This is a job he has been working at pretty successfully for more than a thousand years. Grant him a moment to realize himself afresh in the face of it. Don’t expect him to stop and give a coherent explanation of what he is doing. He wouldn’t be the true son of the English tradition that he is if he could do that. Perhaps the occupants of the new chair can do something of the sort for him.

Fluid Power School Essay Example

Fluid Power School Essay Example Fluid Power School Essay Fluid Power School Essay Essay Topic: We Real Cool Fluid Power School BY Mikecole1911 Original November 10, 1994 BASIC PNEUMATICS FLUID POWER l. Basic definition of Fluid Power: A fluid is any media that will flow when contained in some form of vessel or conductor such pipe, hose or tubing. The media can be air, oil, water, gases etc. The media when moved with pressure or force is capable of producing ready energy, which can be used to perform limitless automated functions. Fluid power is most often used to create linear and or rotary motion. The forms of fluid power discussed in this forum are pneumatic technology with some light coverage of hydraulics. A. Trends with Fluid Power: 1. The field of hydraulics is a growth industry in the USA. The primary cause for this expansion is the fact that many manufacturers in the US are automating a great deal of heavy manufacturing industries in order to compete with overseas developing nations, and the European and Japanese manufacturers that have already been in the automation mode for many years. Hydraulic technology is the heavy-duty muscles of manufacturing, no other form of industrial power provides as much work capability at a competitive cost. Along with this muscle come environmental oncerns, proper disposal of warn out hydraulic oil, old strainers and filters are issues that need to be addressed. The other obvious area is leaks in hydraulic systems are a constant nuisance. 2. Pneumatic technology is growing rapidly every year. This is largely due to many factors; Pneumatic fluid power is clean, less expensive to implement than hydraulics, and economical to use. As the domestic manufacturing base moves toward lighter high tech type industries, compressed air still provide more bang for the Buck than any other power source without the negative environmental effects of hydraulics. : Linear and rotary motion can be generated with great speed, reliability and precision using pneumatic cylinders, air motors and rotary actuators. Compressed air technology has seen great expansion as original equipment manufactures (OEMS) continue to utilize pneumatic systems on their machines and equipment. Most of the time the customer has plant air available for use, but in some cases OEMs are using small on board compressors that are quiet, efficient and capable of producing ample volumes of compressed air at pressures up to 150 psig. The copier industry and medical fields are two major examples. Almost anyone can benefit from a working knowledge of basic pneumatic capability. That is the intent of this seminar, to provide a basic exposure of general capabilities that could be employed to meet the pneumatic needs in your business. Seminar Format: A: Generic presentations of various fluid power components: The basic functions and variations of the major components available in the Fluid Power Industry. B: Review the basic layout of a pneumatic system. 2. FRL Gauges 3. Safety Blow Down Valve (Lockout valve) 4. Directional Control Valves 5. Actuators Cylinders, rotary actuators, air motors, Robotic Grippers etc. Accessories Flow Controls, needle valves, pressure switches, check valves, vacuum generators, relief valves etc. 7. Pneumatic Logic (alternative to PLC) C: ANSI Symbol Handout and Overview: D: Basic Pneumatic Schematic Handout: 1. Review Pneumatic ANSI symbols 2. Walk through schematic Ill. Generic Presentations of Components Compressor: There are several types of air compressors on the market today. The most common are rotary screw and reciprocating piston type compressors. Most compressors require oil similar to automobile engines to extend life and keep them running moothly. This oil is almost always present in the compressed air sent into the plants air system. The oil can be in the form of burned off hydrocarbons, air line or airborne oil in liquid or vapor form. Compressor selection for a facility is not the focus of this seminar, but Component Supply is an authorized Ingersoll Rand Dealer and we can assist anyone that needs to select a compressor for your facility. A full range of portable or on board compressors are also available that range from sizes small enough to fit in the palm of your hand, to 2 horsepower units. These small ompressors generate surprisingly high volumes of air and vacuum at pressures up to 150 psig and vacuum to 28. 8 Hg. These compressors are usually oiless in design and are an industry unto them selves. Liquid handling systems and process control are other areas that can be assisted by the use of fluid power technology. As stated before, anything that flows can be dealt with using this industrys equipment and technology. So keep this in mind for any needs you may have that fit this general description. FRL Gauges: FRLs or filters, regulators and lubricators are used to properly condition the air for use in a pneumatic system. These combination units can be provided in full size confguration or a more compact miniature version. Many people assume that com pressed air is clean by its nature, this is a great misnomer and poor quality compressed air will cause components to wear faster, and inhibit the reliability of the system. Compressed air is a control medium Just as is electricity; it needs to be conditioned from raw form in order to work as expected. Electricity must be filtered and so does air. The contraction FRL is also the order in which the conditioning proc ess takes place. Air is first filtered, and then regulated to the proper working ressure and, in some systems it is then lubricated to improve the function of various components. A pressure gauge mounted to the regulator will indicate the operating pressure in the system. Properly conditioned air is the grass roots toa well-designed fluid power system. Filtration: Particulate Function and dynamics 2. Depth Filtration-Torturous Path 3. Contaminant Removal 4. Water removal -Removes water in droplet form no vapor removal. 5. Element micron size Element Materials Polypropylene and Sintered Bronze 6. Flow rating vs. element rating finer rating yields lower flow. Coalescing Function and ynamics 1 . Oil Removal-Droplet and aerosols 2. Particulate removal-Depth filtration 3. Aerosol removal coalescing style filters filters out oil aerosols and their negative effects to system reliability are removed as well. 4. Life expectancy of the element average 3-6 months. Check the color Brown = need for change. 5. Material is borosilicate glass Pre-Filter desirability, 5 Micron particulate filters extend life and function of Coalescing unit. 6. Flow capability / pressure drop Options for Filters: Polycarbonate or Metal Bowls Automatic and Manual drains 2. 3. Sight Glasses 4. Diverter blocks . Mounting Options A. Nipple Mount B. Modular Mount Systems Maintenance general WATER REMOVAL: Water in pneumatic systems has been a common problem for circuits that use on board oiless compressors. This is because there is usually not much distance between point of use for the air and the compressor the temperature of compressed air is elevated after compression and drops rapidly when it travels through the system. This temperature drops result in the dew point being reduced all the way through the system and developing water as the higher temperature of newly compressed air-cools and expands. In most industrial plant pneumatic systems a refrigerated air dryer is used to cool the compressed air and remove most of the water before it ever leaves the compressor room. Particulate filters are very efficient water removers when the water is in droplet form. Simple heat exchangers such as coiled copper tubing and serpentine bending arrangements have proven VERY effective at getting the water into droplet form. This allows the filters to take the water out of the system and thus improve reliability. Todays technology also allows you more tolerance for water in the system than older types of valve and cylinder esigns. We never advocate water as acceptable in the systems but components that can handle it will make your system more reliable and efficient. Pressure Regulators: What is their purpose in the system 1 . Function and Dynamics Two way normally open valves with diaphragm or piston as the regulation device. 2. Relieving and Non-relieving Styles 3. Regulation ranges 0-20, Instrument, 0-60 Low, 0-125 General 4. Mounting options 5. Tamper resistance Caps, Keys, Removable knobs 6. Maintenance general Lubricators: 1 . Function and Dynamics Sump-siphon tube-bypass check valve needle valve sight ome. 2. Flow required allowing the lubricator to function (2 SCFM Minimum) 3. Forms of Lubricators Fog Type: Fog Type lubricators are best applied for general-purpose type applications where the components are not sensitive to over lubrication or very precise lubrication. Micro Fog Type: Micro Fog Type lubricators are best applied in those applications where the components require fine-metered oil mist lubrication. This type of unit provides a more uniform supply of atomized oil mist. Drop type: Drop Type lubricators are best applied for general-purpose type applications where the omponents are not sensitive to over lubrication or very precise lubrication and the oil mist is not required to be as fine as those created by mist type lubricators. The oil dispensed from drop type lubricators will travel the shortest distance to components. 4. Maintenance general refilling procedures, fill under pressure, button fill features, bowl removal potential wear and failure points. Integral Filter / Regulators 1. Form Function and Dynamics 2. Advantages 3. Particulate Filters are usually the only type available in (Piggy Back) units. Some are now available in Coalescing style units. 4. Safety Blow Down Valves (Lockout Valve): Safety blow down valves are three way valves that shut off the air supply to a machine or system and then exhaust the remaining air in the machine to atmosphere. The primary purpose of this item is for SAFETY. Valves of this type are an absolute must in any machine, control circuit or system. By exhausting the residual air in the machine to atmosphere there is no stored energy in the machine. One last cycle in the machine could crush an operators hand or cause other types of injury. This is an OSHA requirement that should NEVER be ignored. Remember, a 2. 5 ore air cylinder with 80 psig pressure behind it has 400 lbs. of force ready willing and able to do great damage if accidentally cycled. Lockout valves function and features: Lockout or blows down valves are three way valves usually with a palm button or lever actuator positioned to allow the operator to depressurize the machine by hitting the button in an emergency. The air supply is terminated and residual pressure in the system is exhausted. A Lockout Valve: A lockout valve is the same function as described above except a padlock device is also provided to allow a service technician to lock the air supply in the off position. This guarantees safety to the technician when working on the machine; he can physically lock the valve in the closed position. Directional Control Valves: Directional control valves are utilized to control the operation of fluid power actuators or direct the flow of fluids in more than one direction. A single acting actuator requires Pressure in one direction to operate and a spring or load will return it. A three way directional control valve is used to operate a single acting actuator. A actuator. A four way directional control valve is used to operate a double acting unit. These components will be explained in detail later on. There are many functions of valves in industrial automation systems, 85% of all directional control valves for cylinder, air motor, or rotary actuator control are four way valves. Actuator control is not the only purpose directional control valves serve, the designer is really only limited to their own creativity. Valve Function and Flow Patterns Two Way Valves 1. Normally Open (Passing) 2. Normally Closed (Non: Double Solenoid vs. Single Solenoid Valve Design and Configuration 1. Poppet Style A. Armature Style Direct Lift (Direct Acting) B.

Sandwich Flow Controls B. Sandwich Regulators C. Blocking Discs D. Blank Station Plates E. Exhaust Restrictors F. Indicator Lights / Surge Suppression G. Integral vacuum generators attached to valves Cylinders Cylinders provide linear motion that can be used to perform a limitless amount of mechanical functions. Cylinders are available from fractional bore size up to 24 bore and beyond providing a range of forces capable of achieving almost anything. Air cylinders usually employ some type of elastomer sealing mechanism such as an O ring or lip type seals. Hydraulic cylinders sometimes use elastomer seals for lower pressures (1500 psig and below) or automotive style metallic piston rings for higher pressures of 5000 psig and higher. They can sometimes be thought of as air cylinders on steroids. Because hydraulics was the first form of fluid power air cylinders that followed were at first nothing more than converted hydraulic cylinders with soft seals (leather initially) that would be leak free with air. As a result air cylinders were at first ver designed and a classic case of overkill. In the past decades air cylinders have been streamlined and cost reduced to meet the cost/function goals of todays industrial market. There are basically two forms of cylinders, single acting and double acting. A single acting cylinder requires pressure from one direction to extend or retract it, and uses a spring or the weight of the load to operate it in the opposite direction. (Usually operated by a three-way valve) The side of the piston opposite the pressure source must be allowed to vent to atmosphere if its an air cylinder or return to tank if its a hydraulic cylinder. A double acting cylinder requires pressure in both directions to extend and retract the cylinder. (Usually operated by a four-way valve) The side of the piston that is not being pressurized is allowed to exhaust back through the valve either to atmosphere or to tank.

Too Much Lubrication D. Improper Mounting Creates Side Load E. Stroke Length Long Strokes F. Bottoming out on The End Caps G. High Cycle Rates High or Low Temperature Calculating Cylinder Force The force that an air cylinder is capable of producing can be calculated by taking the area of piston diameter and then multiplying it by the airline pressure you have available. You must remember to deduct the piston rod area from the retract side of he piston because your working pressure will not be able to act on this surface. A key point to remember is that fluid power is FLEXIBLE power by reducing or increasing your working pressure you can decrease or increase your force exerted at a known rate. The formula for this calculated using: 0 x roo x Line pressure = Output stroke or rotation of a pneumatic device. Electrical drive mechanisms generally do not have this feature and are limited in stroke or travel. Air Motors Air Motors provide rotary motion with a shaft that can be continuous in either one or both directions. The air motor is an alternate source of power in lieu of the electric motor. Air motors can be stalled without damage or a rise in heat, which is a real advantage over electric motors. Air consumption and exhaust noise is the two major concerns for air motors. It is also important to note that air motors must be lubricated. Vanes are used inside the motor for the air to act on and drive the shaft. There is a known amount of leakage past the vanes when the motor is both stalled and operational. Adjusting the working pressure exposed to the motor can vary the power or torque provided by an air motor. Valve selection and speed control options are basically the same as would be used for air cylinders. A unidirectional air motor is analogous to a single acting air cylinder and a Bi-directional motor is analogous to a double acting cylinder. Rotary Actuators Rotary actuators provide rotary motion to a shaft through conversion of cylinders attached toa rack and pinion or a vane. As the rack and pinion move or the vane moves the attached shaft provides rotary motion usually not more than one revolution or 3600, when the rack or vane is returned to the home position the shaft is also returned to the home position. The actual rotation of the shaft can be specified when ordering usually this is done in 450 increments. The actuator can be single acting and returned with a spring or double acting and returned with pressure. Rotation adjustments are very handy and reduce the need for extreme tolerances of other mechanisms that help reduce overall machine cost. Styles and Rack and Pinion Style A.

Specials Pneumatic Robotic Grippers Grippers are usually used in higher-level automation systems where pick and place type functions are required. Depending on the style and confguration needed the grippers can range from being very low cost to several hundred dollars. Remember one very important fact you can always purchase a better gripper for less money than it costs to design and make your own. 1. Basic Styles A. Parallel Grippers Jaws move in parallel motion.

July 17, 1995 Pneumatic Logic Introduction: Pneumatic Logic is a control medium very similar to electricity. Over the years the popularity of pneumatic control logic has varied depending on several issues such as reliability, cost, troubleshooting, technology and application nvironments. Moving Parts Logic (MPL) Also Known as Pilot Logic, MPL can be used in conjunction with or in lieu of electrical controls on automated machines. This form of control medium was very popular in the 1970s due to lower cost and small size compared to relay electrical control systems. Todays PLCs have closed that gap in a dramatic fashion. Today MPL has its place in hazardous applications such as paint spray booths or areas where a spark could cause an explosion. In automated assembly or automatic machines Pneumatic Logic is still the lowest cost form of Anti-tie Down echanisms and assembly processes that require 5 or less steps. After 5 steps or more the PLC is often (but not always) lower in cost and smaller in size than MPL, it also offers better diagnostics for debug. When used in conjunction with Air Pilot operated power valves, manually and mechanically operated Limit Valves MPL allows for sequencing, time delays, parts sensing, position sensing etc. Almost any automated process can be achieved with MPL. Pneumatic Logic when applied properly is also very compact and highly reliable. 1. Mounting Formats A. Individual Bases
