Virgil Quotations With English Translations

Publius Vergilius Maro (October 15, 70 BCE - September 21, 19 BCE) was the leading poet of the Augustan era. His Aeneid glorified Rome and especially the ancestry of the first Roman emperor, Augustus (Octavian). The influence of Virgil (Vergil) on subsequent writers has been immense. He is responsible for sayings or the sentiments behind sayings that we still use, like Beware of Greeks bearing gifts, from Book II of the Aeneid. All Virgil quotations listed here include a reference to their original location, the Latin that Virgil wrote, and either an old, almost archaic translation from the public domain (mainly for the longer passages) or my own translation. [Lat., Experto credite.]Believe in the one who knows from experience. (Trust the expert.)- The Aeneid (XI.283)[Lat., Non ignara mali, miseris succurrere disco]Not being ignorant of bad things, I learn to help the wretched.- The Aeneid (I.630)[Lat., Superanda omnis fortuna ferendo est.]Every fortune is to be conquered by bearing (it).- The Aeneid (V. 710)[Lat., Quisque suos patimur manes.]We each allow our own ghosts. (We make our own destiny.)- The Aeneid (VI.743)[Lat., Disce, puer, virtutem ex me, verumque laborem; Fortunam ex aliis.]Boy, learn virtue from me, and true work; luck from others.- The Aeneid (XII, 435)[Lat., Saevit amor ferri et scelerata insania belli.]Love of iron (weapon) rages; also the criminal madness of war.- The Aeneid (VII.461)[Lat., Nescia mens hominum fati sortisque futurae,Et servare modum, rebus sublata secundis.]O heart of man,/ not knowing doom, nor of events to be!/ Nor, being lifted up, to keep thy bounds/ in prosperous days!- The Aeneid (X.501)[Lat., S tat sua cuique dies; breve et irreparabile tempusOmnibus est vitae; set famam extendere factisHoc virtutis opus.]To each his day is given. Beyond recall/ mans little time runs by: but to prolong/ lifes glory by great deeds is virtues power.- The Aeneid (X.467)[Lat., Aegrescitque medendo.]He grows increasingly ill with the remedy. (The medicine is making him sick.)- The Aeneid (XII.46)[Lat., O formose puer, nimium ne crede colori;]Oh! Beautiful boy, dont put too much faith on (your) complexion. (Perhaps, beauty fades.)- Eclogae (II.17) *The real version, Nunc scio, quid sit Amor, comes from Virgils Eclogues VIII.43. Not all misquotes are so easy to untangle.

White Privilege Unpacking The Invisible Knapsack

This purpose of this paper is to synthesize this writer s three key revelations from this semester which are, (1) white privilege, (2) curriculum corruption and inadequate United States history education in K-12 public schools, and (3) United States legislation which disadvantages the minor races as a means for the dominate race to maintain power and control. Thus, this exploration organizes each area of significant course discovery, which a hybrid of class sources and readings relating to each area of learning supports. Additionally, this synthesis includes a summary of this writer s social location as well as the course material’s impact on the understanding and interpretation of these themes. Finally, this paper ends with a conclusion and presents final thoughts about the concepts we ve discussed in the Sociology 321 - Race and Ethnicity course throughout the spring 2016 semester. White Privilege To begin, the first pivotal revelation is the concept of white privilege.

Stages of Marketing and Management

Question: Discuss the various stages of marketing and management through various models. Answer: Introduction Every organisation aims to deliver quality products and services to customer to gain acceptance in the market. Various organisation have different approaches towards the same. In this competitive business market, it has become a necessity for every organisation to market their products to attract consumers (Christopher, Payne, Ballantyne 2013). Marketing is the only known process that helps an organisation to welcome new consumers and retain the old ones. A variety of strategic approaches helps an organisation to accomplish their objectives. The report revolves around Telstra, an Australian based telecom company that aims to achieve global acceptance in market. The report describes the challenges of the company, their goals and objectives along with their marketing strategy to attain and retain consumers. The organisation offers a variety of opportunities to separate itself from other companies by focusing on consumer needs, pricing and services. However, Telstra faces certain chall enges such as market competition and ineffective marketing strategy that is affecting the business operations to a huge extent. 5Ps of Marketing Every organisation aims to gain a competitive advantage in the market by serving quality products and services. However, to achieve this long-term objective goal, it is important for the company adopt a proper strategic approach that can help the company to achieve their target (Aremu Saka, 2014). Marketing mix helps the company in preparing a strategy that helps them to market their product prominently in the market place. It is essential for the company to understand that marketing mix and target market selection helps in devising a proper marketing strategy that provides the needed boost to the company. The use of this marketing tool has helped many companies to improve their business process accordingly. Marketing mix helps and organisation to determine the future for their products and services which in turn helps them to understand the market trends and help them to strategize accordingly. In this competitive business world, organisations are competing with each other to gain the market control. Product: in order to dominate the market with full force it is essential for the company to provide services and products to consumers. Telstra provides fixed line services, mobile services, internet services, television services to name a few. As the business market is growing and new competitors are entering the market, it is useful for the organisation to bring a variation in their products and services to retain consumers as well as attain new consumers (Beckmann, Hielscher, Pies, 2014). Telstra provides so many services to the consumers that the company has built a good trust level amongst it buyers. Mainly the company focuses on mobile services as it currently the most trending thing. With the advent of technology, mobile can operate on various areas be it shopping, banking, researching. Therefore, by understanding the trend, the company believes that it is in the best interest of Telstra to provide and improve the mobile services in terms of both consumer satisfaction and sup port. Figure1 Product Life Cycle Every product has a decline stage at some point of time. For many companies, the decline stage comes quickly, for others it takes time. The difference in the statement is many organisation promises excellent services but are not able to keep their commitment. Whereas, there are organisation for whom consumer satisfaction is top priority because it brings them business. Every organisation launches a product in the product that aims to fulfil the objectives of the company. These particular products have a life cycle that sees growth, maturity and decline. A good product dominates a market for a long time that increases the maturity stage of the product that increases the sales of the company and eventually profit (Giacalone Rosenfeld, 2013). Figure2 Telstra Products dominance For this, the organisation has to introduce the product to market to spread awareness about the merchandise. This involves different marketing strategies, branding, promotion of products and others to name a few. Introduction is the stage where the company invests heavy amount to spread the product in the market for initiating sales. Apart from that, advertisement is equally essential as it helps the consumers to understand the product and their need of acquiring the same. Growth is the stage where the consumers starts to learn about the product and purchases the same. This in turn helps other consumers to buy the product due to word of mouth publicity. Maturity is the stage where the product has gained acceptance in the market and consumers trusts the product and purchases it. The duration of maturity depends on the quality of the product and brand (Hutt Speh, 2012). For example, a new organisation introduces a new health drink the market but is not able to increase the sales. It depends on various factors such as product description, quality, quantity and expectations. Since there are many organisation to deliver health drinks to consumers, there is a less chance for the new companies to target the audience as the other product is in its maturity stage (Kim Mauborgne, 2014). Similarly, if the new organisation is able to provide quality products to consumers at a reasonable price, there are high chances that company is most likely to receive boost in sales. In this instance, the branded product sees a decline stage, as the new product of the new organisation has taken over the market. In case of Telstra, the organisation has new products and services for their consumers. The organisation specifically deals in prepaid, post-paid mobile services that has excellent value for money features. This is one of the primary reasons for the company to receive such a huge consumer base. With the advent of technology and development, organisation are assembling new services and plans that can help them to retain the consumers. Since the organisation has a good popularity in Australia, the consumers are more inclined to the company as they deliver excellent services to their valued consumers. Since the company has already many products in the maturity stage, the aim of Telstra is to ensure minimising decline stage. Nowadays companies are improving their products at the growth stage where the company improves the quality of products and services, feature new plans and services to the consumers, enters new market, increase their distribution area, and revises their pricing policies on their products to retain the consumers (Mahoney Weyl, 2014). Consumers expect better after sales services and expect a simple process. In case of Telstra, the organisation believes in the objective of easy to do business with, which states the demands of products that has higher points are intangible that leads to processes that are more appropriate. The organisation believes in providing the consumers a proper after sales service that helps them to retain the consumers. For this, Telstra has upgraded their business processes that reflects on their customer services. The organisation must provide full support to their consumers (Weatherill, 2014). Place: based on the psychology of consumers, the company believes that consumers are more likely to prefer brands that are located in central places of the country. For example, in shopping malls, important cities, showrooms etc. in case of Telstra, the company is available in almost every prime locations of the country that helps them to draw more consumers. However, based on the scenario, the company does not have a proper distribution channels to less important cities. Therefore, it is essential for the company to establish new networks in places that can draw new consumers (Day, 2011). Place is an important aspect in business which shows the power of the company. For any organisation, place of business is an extremely important place as it helps them to sell their products accordingly. It is important to determine the effectiveness of the place to ensure that the investment is recovered and the company does not suffer losses. In case of Telstra, despite having stores in shopping malls, exclusive stores, the company also believes in providing the consumers the ease of choosing their products while sitting at their home. Figure3 Telstra Promotions The participation of e-commerce has definitely helped the company in achieving more consumers in recent years that it took them a decade to build. Apart from that, the company believes in installing stalls to prominent places to attract new consumers. This ensures the company to increase its consumer base. The competitive advantage of Telstra is that it has more effective signal quality all over Australia, than any other competitors. The organisation believes in providing the consumers pleasant visits to the stores thereby making the shopping experience innovative. Apart from that, the stores are located in some of the prime locations that attracts consumers of all potentials. The organisation follows the trends and technology and adjust as per the new trends (Vargo, 2011) However, Telstra must take a more comprehensive approach to their product prices and should interact with their consumers more to understand their expectations and grievances. Intensive Distribution: intensive distribution involves the use of all available markets to distribute their products. In this distribution style, the consumers gets to select from a variety of products (Sethuraman, Tellis, Briesch, 2011). These outlets tend to have all variety of products of different brands and consumers can select any product as per their requirement. The advantages of intensive distribution includes the idea to incorporate products that are necessary in everyday lives. This affects the money, product awareness, impulse buying which in turn benefits the retailers and consumers and the manufacturers. On the other hand there are certain disadvantages in intensive distribution such as low price and margin, control of the retailer and money. It is essential for the company to determine the proper channel to distribute the products to enhance the business operation of the company in the selected market. Selective Distribution: Using limited number of outlets are a part of this distribution in this distribution strategy, the consumers look for the best performing products and tend to explore various markets looking for them (Sheth, 2011). This is also increases the needs amongst the consumers. Big brands often have control on the distribution of their products as they only provide products and services to a limited number of stores that shares the vision and aims of the company. It is important to understand the demand and necessity of the consumers and provide appropriate stocks to the retailers to enhance sales and have con trol on the priceing and profits. Exclusive Distribution: exclusive distribution is mainly seen in those circumstances, where the availability of the product is scarce. Many consumers tend to look for this specific product, as they desire to acquire it. In business market, exclusive distribution involves the use of only one distributor of a specific geographic location (Srinivasan Hanssens, 2009). Telstra uses the Selective distribution strategy, as the product pricing is high and not available to everyone as of now. Therefore, the company believes to market their products selectively thereby maintaining the leadership position in the business market. A positive consumer is more likely to bring new consumers for the business whereas a negative consumer can hamper the reputation of the company. In case of Telstra, the company believes in providing excellent service quality to the consumers that help them to retain the consumers. However, in respect to productivity, the company lacks to meet the deadline due to no tra ining of employees. As technology improves from time to time, therefore the necessity of providing training to the employees is equally important to meet deadlines (Filistrucchi et al. 2014) Figure4 Telstra Distribution worldwide Promotion: In order to maximise sales, promotion of a product is necessary to bring visibility of the product to the consumers. It is important for the company to promote products due to market competitions. Many organisation uses print media as their primary source of promotions as newspaper and magazines are a part of human life (Chen, Fay Wang, 2011). It is an essential tool for the companies. In case of Telstra, the company advertises in various media such as radio, television, hoardings, and brochures. However, with advancement of technology and the power of internet, the company now advertises on their websites and use social media such as face book, twitter, Instagram, and YouTube as their source of advertisement. In order to increase the sales of the company, promotion of a product is very important. The company is using transit advertising, print advertising, and other forms of electronic advertisement to promote their newly developed products and initiate sales. It is cruc ial for the company to understand the necessity of promoting products in areas of low visibility to increase and capture the available markets. Productivity and quality are perhaps the most essential elements in business to ensure success. Providing quality services to the consumers is very important as it helps the company to receive new consumers through word of mouth publicity (Engelen Brettel, 2011). For example, the company has been installing Telstra telephone booth in new areas to gain visibility in the market. Figure5: Telstra Booth Price: price is another factor that plays an important role in the business. In perspective of the company, it is essential to recover the costs, however in case of consumers; they expect appropriate pricing based on product and services (Chen Shaffer, 2014). In case of Telstra, the organisation has always maintained a leadership position in the market for which the price of their products and services are high. Nevertheless, the consumers appreciate the services of the company and therefore believes it to be appropriate based on the services. However, in order to grow the consumer base, it is essential for Telstra to revise their pricing strategies in relation to their products or develop new products and services that can target all types of consumers (Webb et al. 2011). The company uses premium pricing strategy as the organisation believes that the services they provide to the consumers are quality and has no flaws. The responsibility if the company is to enhance and revise the p ricing policies to ensure that the companies are able to gain market control in the new market areas by changing their strategies towards pricing. Partnership: for any business, consumers are an integral part. Without consumers, the flow of business does not occur. For Telstra, consumers or people are tangible elements to business that help the company to achieve their desired goals. However, it is equally important for the company to understand their employees as well. The company provides the employees appropriate training after recruitment. Apart from that, the employees should be able to understand the problems of the consumers and provide them with proper solutions. Problem-solving skills are also important to the company and therefore they hire employees with communication skills and ability to handle clients (Dong, Kouvelis, Su, 2014). In case of Telstra, the company must provide appropriate services to consumers. Appropriate training to the employees of the organisation can help them to minimise the level of errors. The organisation has tied up with many well-known companies like Diligent for their cloud services, tied up with San Miguel Corporation, Navman Wireless and others to name a few. Figure6 Telstra Market performance Consumers expect better after sales services and expect a simple process. In case of Telstra, the organisation believes in the objective of easy to do business with, which states the demands of products that has higher points are intangible that leads to processes that are more appropriate. The organisation believes in providing the consumers a proper after sales service that helps them to retain the consumers. For this, Telstra has upgraded their business processes that reflects on their customer services. The organisation must provide full support to their consumers (Weatherill, 2014). Recommendations Expanding to new market areas can help the company to attract new consumers and gain control over the market. Since the advent of technology, the company has been trying to increase its network to all over Australia to provide the best signal quality and therefore the company must expand to new areas like Asian market, or third world countries to gain global acceptance. Apart from that, expanding to new areas also helps in gaining internationalisation. In addition to that, the company must consider revising their pricing strategies as it does not attract consumers of all types. In order to gain dominance in the market, the company must provide appropriate opportunities to the consumer. In addition to this, the consumer should also see a variation in their products and therefore should launch new products that suits all types of ages. These strategies are beneficial in providing the consumers and the retailers appropriate market. The company should revise their products and pricing to ensure appropriate consumer services and sales. In doing this the company can access new markets through their publicity and promotion respectively. Telstra provides the benefit of consumer service and should therefore extend its business operation to different areas of market. It is essential for the company to understand that new consumers can increase the market competition for the company in relation to their competitors. The pricing strategies of the company are high which leads to limited consumers. Changing the pricing of the products helps in developing new consumer relations. Since the company expanded it business into different areas, appropriate marketing provides the window of involving new consumers and retaining the old ones. A positive consumer spreads the publicity for the company when they are satisfied with the products. Hence it is crucial for the company to maintain their products and service offering appropriately. Conclusion The report discussed the various stages of marketing and management through various models. The report explored the various problems of the company in relation to marketing mix and provided necessary solutions that can help the company to make proper business decision based on the market demand. The learner has discussed the issues of the problem critically thereby making the information productive. In addition to that, the report also discussed the possible solutions to the problems in order to maximise consumer retention and attraction.

Study Case free essay sample

Golden Bear Golf, Inc Golden Bear Golf, Inc. The assertions that were relevant to Paragon’s construction projects are: existence and occurrence, completeness, valuation or allocation, and presentation and disclosure. Existence and occurrence: should have been used to test the revenue and gross profit on its construction projects. By testing to see if the assertion is appropriate to make sure that all revenue and gross profit exist would have brought the attention to the $4 million of un-invoiced construction costs that materialized at the end of fiscal 1997. This assertion test also would have revealed that the earned value method in practice was allowing Paragon to book much larger amounts of revenue and gross profit on its construction projects than it would have under the cost-to-cost method. Completeness: the SEC said that Sullivan and his subordinates should have rigorously tested Paragon’s large amounts of unbilled revenues at the end of 1997. A significant amount of unbilled revenue that is reported as complete should be tested to determine the reason no billing has been posted for the work that was done. We will write a custom essay sample on Study Case or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It also should be determined the reason income is being recognized for jobs that have not been identified as works in progress to determine the exact completion date of the project. By testing this assertion it would have been discovered that $4 million of work was fictitious. Valuation or allocation: Paragon overstated its revenue and profits by using the earned value method which caused a huge increase in unbilled revenue by the end of 1997. Approximately 30 percent of the 1997 income statement had not been billed to its customers. Paragon also overstated the revenue to be earned on its individual construction projects, and during the 1997 audit, Andersen personnel used thirteen of Paragon’s construction projects to corroborate the total revenue figures the company was using in applying the percentage-of-completion accounting method to its unfinished projects. If the valuation and allocation test would have been applied, the overstatement of revenue and gross profit could have been detected and prevented.Presentation and disclosure: if Andersen had used the recommendation from the AICPA Audit and Accounting GuideConstruction Contracts, he would have found out that some of the Paragon’s projects did not exist and he possibly would have determined that Paragon was overstating the completing stages of most of its existing projects. My belief of what the SEC meant by the phrase â€Å"audit failure† is that Sullivan did not practice his knowledge to make sure that Paragon accounting system was i n compliance with General Accepted Accounting Principles (GAAP) and General Accepted Auditing Standards (GAAS).One reason that Sullivan was at fault for the allege audit failures is he did not test the large amounts of unbilled revenue and relied â€Å"excessively† on oral representation from Paragon management to confirm the unbilled revenue and corresponding receivables. Another reason is that Andersen auditors discovered that the total revenue being used in the percentage-of-completion exceeded the revenue figure documented, and although no documents were recorded for these oral representations, Sullivan accepted that the revenue amounts given were valid.Yes, I do believe that Sullivan was responsible for the final outcome of the deficiencies that the SEC noted in Andersen’s 1997 audit of Golden Bear. My reason for saying he should accept full responsibility is because he was a partner in Andersen and he as the leader of the audit had the final say so about what was accepted from the company and what was not.When the information about the unbilled revenue, overestimate of the project’s stage of completion, and the total revenue being used in the percentage-of-completion computations exceeded the revenue documented, he should have stopped doing the processing of the audit at that particular moment and required for more assertion test to be performed or he could have refused to continue the process of the audit if Paragon would have refused to comply to the additional test.The audit engagement team’s responsibilities to determine if an engagement is a high-risk or normal-risk engagement are the same. They both use the audit risk model to determine the inherent and control risk to detect if the account contains errors that could be material when combined with errors in other accounts and detection risk that the auditor will not detect material errors. By using the audit risk model, it would help in determining the substantive audit procedures needed for testing.The factors that prompted Sullivan to designate 1997 audit a high-risk engagement are the subjective nature of the earned value method; Paragon’s large unbilled revenues; the aggressive revenue recognition practices advocated by Golden Bear management; severe weaknesses in Paragon’s cost accounting system. These factors should have alerted Sullivan and his subordinates to be particularly cautious. No it is not required for auditors to refer to the Audit and Accounting Guides provided by the AICPA for specialized industries.Although it is not a requirement, it is a great reference on how to perform and handle an audit related to the particular industry that is being audit if it is provided. If you use the guide that is available it will help on giving you an idea about the possible procedures and testing that may be required to perform a successful audit. It is also helpful in case a question arises that may have been of the same nature in the recommended guide. The guides do not override or replace the authoritative guidance included in Statements on Auditing Standards, but it does help support the standards.

Explorations in Arthurian Legends

Explorations in Arthurian Legends The legends tell us that Arthur was a wise and powerful king, who ruled from a giant and glorious castle and who commanded the loyalty of hundreds of men.First and foremost of these followers were the Knights of the Round Table. That greatest knight in skill of arms, Lancelot, pledged his loyalty to Arthur, is testament to the fact that the king was worthy of such admiration, both as a king and as a warrior.War was a way of life in Arthur's day. Just after he pulled the Sword from the Stone, he hurried to Bedegraine and defeated a rogue band of 11 powerful men who had rebelled against his leadership.He faced constant pressure from the Saxons and the Picts and the Irish and the Romans; in the end, he faced a mortal threat from his own men.He was also the backdrop against which many other adventures took place.English: LancelotBeginning with Chretien de Troyes, writers wrote adventures of Arthur's knights, telling us of their wonderful adventures and of courtly love. The court, of cour se, was Arthur's. In a sense, Arthur was moved above the day-to-day adventures his knights having and put on a pedestal as the symbol of what a knight could hope to achieve.He was also the one whom everyone looked up to and whom everyone trusted to pass judgment if they had a dispute. Important men bowed to his authority and his wisdom. He held court and was the arbiter of justice. He made his own laws and enforced them himself, with the respect of his subjects. He fought in battles and sent his knights out to do battle. As such, he was both king and battle commander.Later, Arthur was said to have conceived a son out of matrimony; Guinevere was said...

Crystal Easter Egg Project

Crystal Easter Egg Project These crystal Easter eggs make great decorations! Basically, you grow crystals around a real egg. You can make a crystal geode, an egg decoration or a hanging ornament for an Easter egg tree. Make pastel eggs or vibrant eggs in any color of the rainbow. This is an easy crystal growing project that yields quick results. Time Required a few hours to overnight, depending what you want Materials You can use pretty much any recipe for growing crystals. Good choices would include sugar, salt, Epsom salts or borax. I chose alum because I wanted large crystals on the egg and quick results. If you want to completely coat your egg with sparkly crystals, borax or sugar would work best. The amount of borax, sugar, salt or Epsom salt is different from the amount of alum. Basically, keep adding material to the boiling water until it stops dissolving. Use this saturated solution to grow the crystals. An egg1 cup boiling hot water4 tablespoons alum (which is the size of a typical container in the grocery store)A pin or needleFood coloring or Easter egg dye (optional)String or a pipecleaner (optional)Cup Prepare the Egg You have a few options here. Crystal Geode EggIf you want to make a geode, carefully crack the egg or cut it in half. Rinse off the shells and allow them to dry before continuing.Crystal EggYou can use a hard-boiled egg to make your crystal egg. This results in a heavy egg that can be used as a tabletop decoration.Egg OrnamentUse a pin, awl or Dremel tool to pierce a hole into each end of the egg. Push the pin or an unbent paper clip into the egg to scramble the yolk. Blow into the hole on one end of the egg to remove the egg. If you have trouble, try enlarging the hole. The crystals will grow over the bottom hole, so it isnt critical to have an inconspicuous hole. Make the Crystal Egg This is how I made the egg in the photograph: Pour 1 cup of boiling water into a glass.Stir in 4 tablespoons of alum. Keep stirring until the alum dissolves.If you want colored crystals, add a few drops of food coloring. The eggshell picks up color easily, so a little dye goes a long way.Put the egg in the glass so that it is completely covered by liquid. If you blew out the egg, youll need to submerge the egg until the air bubbles escape or else your egg will float. If you like, you can suspend a hollowed egg using a pipecleaner or string.Allow a few hours for crystal growth. Once you are pleased with the crystals, remove the egg, hang it or set it on a paper towel, and allow it to dry. This egg has large sparkling crystals that show the shape of the alum crystals. If you want alum crystals all over the egg, seed the egg before putting it in the solution by dipping it in alum powder or painting the shell with a mixture of alum and glue. Crystal Egg Recipes Sugar Crystal EggDissolve 3 cups of sugar in 1 cup of boiling water.Borax Crystal EggDissolve 3 tablespoons of borax into 1 cup of boiling or very hot water.Salt Crystal EggThe solubility of table salt or sodium chloride is highly dependent on temperature. Stir salt into boiling water until it stops dissolving. Sometimes it helps to microwave the solution to a rolling boil to get the salt into solution. Its okay if there is some undissolved salt at the bottom of the container. Let it settle out and then pour off the clear portion to use to grow your crystals.Epsom Salt Crystal EggDissolve 1 cup of Epsom salts (magnesium sulfate) into 1 cup of very hot tap water.

Market strategy, Market positioning and Marketing-Mix - Assignment Example Furthermore, Metrao faces increasing competition from other calorie calculators being sold in the market. Generally, this means that Metrao is obliged to differentiate its products from others in the market by being innovative and unique. In addition to, the calorie calculator market is growing showing that there are likely to be diverse consumer needs and expectations. Consequently, Metrao should utilize strategic marketing tools to get an actual picture of the level of competition in the market and the customers’ needs. A marketing strategy is a process that enables a company to focus its limited resources on the strategic opportunities to attain a sustainable competitive advantage and increase their sales volumes (West, Ford, and Ibrahim 57). A marketing strategy should be based on consumer satisfaction. A marketing strategy is made up of different aspects such as pricing, product development, promotion, distribution and relationship management. Further, it establishes the choice of marketing mix, positioning, target market segments and relationship management. Some of the strategies adopted by the company include the PESTLE and the SWOT analysis. Marketing Mix This primary marketing strategy adopted in the promotion of Metrao. Generally, four aspects in the 4Ps strategy include product, place, price and promotion. The first element of the marketing strategy is product (Schroeder 11). Product refers to the product or service being offered in the market. Metrao is a calorie calculator that enables people keep track of the calorie intake on their daily basis for healthy purposes.

In other words, the company is undertakes promotional pricing to generate profits and compete with other players in the market (Robinson 78). However, the company intends to set a reasonable price once the consumers are fully aware of the existence of the product in the market. Promotion is the way in which information about a product is brought to the attention of the consumers. The company has a brand name and intends to raise its awareness using a wide range of advertising campaigns staged on offline and online marketing channels. The company also promotes its products on its website that was recen tly established to target the online market segment. The final aspect of the marketing mix is place and it relates to where a certain product can be purchases and how the buyers can easily access it. The product will be available in the company’s stores, the company’s website and other shops that sell health related products. The product will be sold in the UK and if it performs well, it will be introduced in other parts of the world. SWOT analysis The company

Moving Image- Films Research Paper Example | Topics and Well Written Essays - 3000 words

Moving Image- Films - Research Paper Example The current outflow of talents from Mexico is as diverse as it is compelling. From the likes of actors such as Diego Luna and Gael Garcia Bernal who have received acclaim internationally through the movie â€Å"Y Tu Mama Tambien† (And Your Mother Too) to the breakthrough of directors Alejandro Gonzalez Inarritu and Alfonso Cuaron and other prominent talents such as screenwriter and director Guillermo Arriaga. The contribution of Mexico to the world of film is more than notable. Quite possibly one of the most influential directos of all time, Luis Buà ±uel, who although was born in Spain worked for most of his life in France and Mexico. Known for his surrealist take into directing and as evident in his films, Buà ±uel was known for being an inspiration to other well-loved directors of all-time such as Alfred Hitchcock and Devid Cronenberg. His style is often attributed to an uncomplicated and elegant touch oscillating back and forth between its unusual intricacies (Walls, par. 3). Known as the film industry’s founder of the Surrealists, Buà ±uel won an Oscar for Best Foreign Film in 1972 for the movie The Discreet Charm of the Bourgeoisie. He is also known for collaborating with another famous Spaniard Salvador Dali during the 1920’s. Although he scorned his previous works in comparison to the ones he made in France where he was provided with augmented budgets and an almost complete artistic freedom, the grit of his earlier works makes much for his compelling artistry. Later on in his career, his films had such an aura of complacency about them. Maybe this is due to the artist’s warranted comfort and contentment in his career (Walls, par.4-5). The year 1992 marked an enormous hit to the movie industry of Mexico. Seeing the slump of movie making, former president Carlos Salinas removed the limit on the prices of tickets, gave up control on government-owned theaters and completely opened the market to Hollywood films. Deregulation brought forth three adverse

The war at sea Essay Example for Free

The war at sea Essay Despite this fact they were only a side show to the Western Front. Aeroplanes were significant to the war effort as they brought glamour and gave cvillians and soldiers on the Western front hope as well as heros to believe in. This boosted the morale of the nation and helped the war at sea, on the home Front and on the Western Front. The Home Front: The war of 1914-1918 was the first war thathad an impact on everyone. No longer did a war involve sopldiers or men in the armed forces alone. Helpless civilians were also affected. The first world War touched everyone at some point throughout its duration, and people who lived in cities were the victims of bombardments by enemy planes. The First World War was the fist time that blackouts were introduced, this was so German planes would not know when they were opver a city. The alarm would sound and everyone would take cover intheir bomb shelters until a second alarm sounded to say it was safe to come out. When the war started Britain had only a small professional army. The government decided to invest a lot of money into advertsing aspects of the war; fighting for ones country and trying to encourage patriotsm. Posters and leaflets were plastered everywhere to promote and encourage recruitment to the armed forces. Propoganda was vital to ensure men signed up. The British press reinforced the governments recruitment drive with tales of German atrocities such as the murder of babies and nurses and the raping of HELPLESS WOME. One of the most popular stories of the time was that of German factories making soap from boiled corpses. The campaign to enrol men was very succesfull and by 1916 over 2 million had enlisted. In 1916 the government introduced conscription for men between the ages of 16 and 40 for the first time. This was due to many reasons; the number of men volunteering for the war was dropping, the lower classes were conscribing which was crippling the agricultural system whilst the upper classes did not volunteer. The war effort was only attracting certain people and it was felt by most that not all men were playing their part. Conscription meant that everyone, from all walks of life, helped their country. Not everyone agreed with conscription, many members of parliament voted against it. Others did not go to war due to political or religious beliefs. They were called conscientious objectors or conchies. They had to appear in front of a tribunal to prove that they had valid reasons. If not they were often put in prison where they were badly treated. Some chonchies helped at the front as stretcher bearers; these men had a life expectancy of about 3 days. In 1914 the government introduced DORA this stood for the defence of the Realem Act. This gave the government a wide range of powers, some of which included censership of what the publicfopund out about the wa and what enemy countries found out about the allies, thus ensuring no piece of information got into the wrong hands. The government was able to use any building as part of the war effort and to take over various industries including the coal industry, ensuring that business men did not profit from production. In 1915 the munitions crisis occurred due to the stalemate on the Western Front as armament and weapons were running out. Men had to train with wooden sticks as there were insufficient rifles to equip each man. The bombardment of enemy trenches could not continue if there were no shells. Some soldiers were only allowed to use 3 rounds of shot per day. The situation was looking dire for the government at this time. The daily male put the national scandal into circulation and as a result a coalition government was formed so that all parties could work together. Lollyd George was made Minister of Munitions. One of the initial problems of the munitions crisis was that too many skilled young workers had gone to war in search of better pay. The government had to recall many of these men. Another key constituent of Llyod Georges plan was to introduce women to the work force. In 1915 100,000 women enlisted for work however only 5,000 of these got jobs. The unions were worried that when women took the jobs they would dilute the salary of the mens jobs. Llyod George clearly ststed that women would earn the same amount as men and that their jobs would be complete when the war was over. Many women worked in the munitions factories and by 1915 the situation had improved and helped all fronts. It is recognised that without the assistance of the women the war would probably been lost. As men left for war an increasing number of women went into the professions usually dominated by men. Women went into all fields of work including ship, coal , steel, transport and agricultural (land girls) industries. However their made impactwas in the munitions factories. Here the women were in high risk jobs which affected both their skins and their lives. Toxic chemicals turned their skin yellow and they were often labelled canaries as a consequence. Women payed the ulimate price as many of the died of the cancer these toxic chemicals caused. In1917 women aged over 30 were given the right to vote. The war had help[ed the men of the country to realise that women were a part of a functioning Britain and that they to had a voice that needed to be heard. Asquith a former priminister, supported votes for women during the war although he had previously aposed this when in power. The attitude towards women and their role changed as a result of the war. Under DORA the government had the right to secure land and use it for farm production. In 1917 the government had a problem, there was a shortage of food. A quarter of British ships were being sunk by German U-boats in April and there was supposedly only six weeks of wheat left. As supplies ran low prices rose. Shops closed early as they ran out of food. Poorer families starved whilst the rich hoarded all of the food they could get their hands on. The government reacted in a variety of ways. The earnings of industry workers rose and in May 1917 voluntary rationing was introduced. The Royal family led the way by stating that hey were reducing their ingestion of bread and such products by 25%. Posters were designed to encourage economical consumption and in November the nine penny loaf was introduced. None of these measures were affective so in 1918 compulsary rationing was introduced for bread, sugar, meat, butter and beer. Each fam,ily was given a ration which was stamped when anything was bought. There were heavy fines for those whgo tried to break the rules. Rationing was welcomed by most and even improved the health of poorer people by the ne dof the war. The Defence of the Realm Act also controlled the news that flowed in and out of Britain. The british press was heavly censored and even the House of Commons was not always kept informed of the goings on at the Western Front. Journalists were banned from travelling with the troops in case stories were leaked to the British public, thus maintaining morale amongst civilians. In 1916 the british government had to overcome one of its greatest challenges, the filming of the battle of the Sommme. The battle had raged on and many lives had been lost for only a few square miles of land. The film sold out in cinemas all over the country. The footage was unique and showed dying soldiers, and men going over the top. The nation appreciated the tone of the film and although people were shocked they appreciated the films realism. The film was a huge success and saluted as a great piece of cinematography. For the government it achieved its aim by showing the public that despite the absurd and horrendous number of casualties, the war was a worthy cause. Propaganda was used to keep up morale as well as uniting all against the enemy. The Home Front was as important and as vital as the other fronts. It supplied the troops with munitions and the patriotism to convince those at home that their sacrifice was for a deserving cause. This would not have continued without the propoganda and the governments policy of protecting the public from hearing news that would destroy their trust. The Home Front was succesfull due to the efforts of many women who were able to show the men in power that they were as good as them. On a political the Home Front gave women confidence and a certain amount of admiration from the countries men. The war wopuld not have been won without this and was beneficial to the success of the Allies, but it also needed the help of the other three fronts to succeed. Western Front: When the war was first declaired in 1914 it was expected to be over by Christmas. The public thought that it wopuld revolve around gallant young men on horse back charging against the Germans and thus winning a lightning victory. They could not have been more wrong. As sson as war was declared the Germans put the Schlieffen Plan into operation. Their aim was to secure victory over France within six weeks and then turn their attention to Russia in the East. Al;l would have gone according to plan if Belgium had not put up such heroic resistance against Germany and delayed them. The German commander Moltke had also to send a 100,000 troops towards Russia who had mobalised more quickly than anticipated. The Germans were heading towards Paris but were held up quite dramatically by the British troops even though they outnumbered the British. The French launched a direct and grand attack on Germany but were halted by machine gun fire. The Germans gathered their troops and headed towards Paris. However the German troops advance too quickly and ran out of supplies, the German soldiers were also exhausted. The Allied troops desperately tried to save Paris without France, Britains chief Ally, the war would be over. The Germans decided not to advance on Paris and instead chose to go around and attack the French from behind. The French stopped the German advance on the river Marne but were unable to force them to retreat. By the 8th of September each side had dug in to protect themselves, using barbed wire, snipers and machine guns as a means of defence. These were the first signs of stalemate. This stalemate lasted until 1918 with millionsof lives lost and no land gained. The trenches stretched fro the sea in the North too the Alps in the South. The Germans launched several attacks on various Forts in Verdun and both sides resourced the battle. By 1916 700,000 men had been killed and then French were close to collapsing. To help the French the british led by Hague launched their offensive at the Somme, after a week of bombardment the British advanced. There were 57,000 casualties on the first day and by November 1. 5 million men had died. The atrocities of the battles of Verdun and the Somme were something the politicians and the public were unprepared for. Military leadership was criticised and Hague became known as a bad commander; a butcher who knew nothing about modern warfare. Hague was used to the old style of war and was not prepared dor the way things were in the new age of technology. At these battles new technology and tactics, like the introduction of tanks and creeping ambush, set a presedant for future wars. The Battles of Verdun and the Somme have sinced been recognised as a turning point in the war although at the time they were thought of as a complete disaster. In 1917 the Americans joined the war after the Germans declared unrestricted warfare on American ships suspected of carrying armaments for the Allies, although America maintained neutrality. The Germans accused the USA of having double standards. When the Germans tried to ally with mexico it was the last straw and America declared war on Germany on the 1st April 1917. Although this was good news the Americans did not arrive immediately in force and the French continued to struggle. Top make matters worse the Russians had made peace with the Germans in 1917 as a result of the Russian Revolution and the new communist regime. This was bad news for the Allies. It meant that Germany could now mobalise hundreds of thousands of troops from the Eastern to the Western Front. The German force increased as their army was no longer spread across Europe. A final attack was planned under the command of Lundenhoff. However the power of Germanys army had diminished as they were weak and tired. The troops were starved and their whole final offensive failed largely due to the malnurishment of the troops. Although the Germans had ended the stalemat it was the Allies who benefited. The Americans were sending troops at a rate of 50,000 men per month. The troop swere assisted by technologically advanced tanks, aeroplanes and improved artillery. In 1918 the Allied counter attack along the Western Front had reached the Hindenburg line and by October the Germans were in full retreat. When the November Armistice came into effect the Great War was finally over. The Western Front was considered the most important by some. The public views of The Western Front was far from reality. Letters from soldiers fighting on the front were censored and changed so that the image of the heroic battles the Allies were fighting were not destroyed by the truth. It was feared that if the truth were known it would result in havoc amongst the Allied Nations. Civillians new nothing about the terrible conditions of the trenches and propaganda made the war look muchmore glamerous than it really was News papers painted victorious pictures of trench war fare and the public new no better as this was the first technically advanced war ever. The film of The Battle of the Somme, changed that image and people became more aware of the tragedy of loss. Recruitment numbers reduced during the war which was why conscription was introduced. Each of the fronts played an important part in winning the war. The public viewed the Western Front as the only War Front as this was where most of the soldiers were sent, although others were sent to Gallipoli, The Balkans and the middle East. The Western Front had the most casualties which is why it will always be perceived as the most important. The war in the air was vital for surveillance, advancements in aviation and morale boosting. It gave the public something they could understand and belive in. The war at sea proved to be a turning point for the Allies. The Allies starved the Germans into surrendering, thus weakening them and rendering their last offensive unsuccesfull. The war at sea brought the Americans into the picture at a time when the Allies needed reinforcement. The Americans brought with them artillery, equipment and strong healthy men at a time when they were most needed. The war at sea also supplied the troops on various fronts with food and ammunitions so that they were as strong as circumstances would permit. The Home Front was the provider of men for enlistment, was the center for propaganda and made ammunitions and artillery to be used by the troops. DORA was introduced as part of the Home Front offensive to protect civilians and information, and brought women into action replacing the men who were away. The Home Front also provided nurses and kept the nation at Home running smoothly so that the men could return to an organised country at the end of the war. The Western front was where the fighting took place where thousands of men died and where some of the most heroic and dangerous battles ever took place. The men on the Western Front clearly had the hardest task with variable weather conditions and the dreaded over the top manoeuvre. It was also the most traumatic but it would not have succeded without the help and combination of the other three fronts. The Allied victory was due to an imalgamatoion of effort from all the fronts.

Psychology discussion Essay

The findings from this research that trigrams in an organised list will be recalled better than those in a disorganised list have supported the evidence of Millers theory. Miller (1956) found that the magic number 7+-2 can be increased using the method called chunking. This would relate to this piece of research as the amount of individual letters remembered was a lot bigger than the value 7+-2. Participants in the organized condition on average recalled about twenty one letters, and in the disorganized condition they recalled about nine letters. This supports Millers view; that more items can be remembered if they are recalled in â€Å"chunks†. This experiment can be extended to investigate the theory of expert chess players having better chunking abilities than novice players (Chase and Simon (1973)). The expert chess players could recall more information about the relationship of chess pieces than those of amateur chess players, the expert’s could recall up to 30 pieces of information, compared to only seven pieces for amateur players. This links to my experiment because using the technique chunking on an organised and disorganised list of words, led to an improvement in the number of trigrams recalled in the organised condition rather than the disorganised condition. In the organized list around 21 individual letters were recalled, compared to only 9 in the disorganized list. This supports Chase and Simons view that chunking can lead to better recall. My experiment was based on a previous study by Bowers in 1969; the results produced are similar to those obtained by Bowers. Table comparing the result of my study and Bowers study: This Study Bowers Study Average words recalled % of Words Average words recalled % of Words Organised 7. 1 71% 16. 9 65% Disorganised 2. 9 29% 4. 94 19% The results are quite similar although the results above have a higher percentage of words recalled for both the organised and disorganised list compared to Bowers results, however this is due to the fact that more words were involved in Bowers list: – 26 compared to the 10 words used on my list. This will have had an affect on memory as the participant is challenged to remember more words. Bower used a theme of minerals; whereas in my experiment it involved a mixture of random trigrams. This could have affected the ability to recall; especially if Bowers’ participants had greater knowledge than others. However this problem did not occur in my experiment as it was not based around one particular theme. On the whole my results are similar to those obtained by Bowers. E2- Strengths and Weaknesses of the investigation: A strength of this investigation was the method used. This was a laboratory experiment. This method was very reliable and accurate as it allowed manipulation and full control over the variables (i. e. whether the participant is given the organised or disorganised list of trigrams). Therefore the results which were obtained were reliable, and the experiment could be easily replicated by another researcher. A strength of this experiment was that ethics was taken into consideration as informed consent was used to gain approval from the participant, to take part in the experiment. Participants were told they were taking part in a psychology experiment. Also confidentiality was abided by as well as all participants had the right to withdraw there results at any time, also none of their personal details were taken such as names and address. A weakness of this experiment could be the design; as an independent groups design was used; there may have been individual differences between participants. As those participants in the organized condition may have been more intelligent than those in the disorganized condition; this could have lead to them recalling more trigrams than those in the disorganized condition. E3- Consideration of alternative method: An alternative method could be used to test the affect of organisation on memory recall rather than an experimental method. A field experiment can be used so the test can be carried out in a natural setting. The new test can be carried out in school; for example a teacher can carry out an examination on students by testing a group of students to remember a list of abbreviations. This would be testing the ability to recall organized trigrams. Another classroom could be asked to play a game; where their partner gives them three random letters; if they answer a question wrong in a quiz they must recall the three letters they were told at the beginning. A new disorganized trigram would be used every time a question was answered incorrectly. This would then allow you to test the ability to recall disorganized trigrams. An advantage of this over the other method is that it would be carried out in participant’s everyday settings; therefore it would be more realistic, which would give the experiment more ecological validity. This method will also reduce demand characteristics. Students will believe that this is a real test, and therefore they will pay attention and take the task seriously. Although they will not know it is a task into memory; they will believe it is an important test. This method would be relevant for the aim and hypothesis of the study, as it would show if there is a clear difference, in the organized and disorganized trigrams recalled and it would also improve the reliability of the results. E4- Application of findings and suggestion for future research: In conclusion, this investigation has found that 16-18 year olds on average recall more trigrams from an organised list than a disorganised list. This research has proven that chunking and organization does increase the capacity of short-term memory. Therefore a link can be made to the real world for example if someone has to remember security numbers or phone numbers. Short codes can be chunked into one unit, although longer series of numbers like phone numbers may be chunked into two or three sections. This will help to aid recall, also chunking and organisation can help with revision. For example, by revising from notes arranged in an organised style this should organise the data in the brain and encourage better recall in exams and therefore good exam results. This research can also be applied when people do daily shopping. For example items of a similar nature can be chunked together into one group, e. g. , peas, cabbage and broccoli could be chunked under a vegetables group, so that they can be remembered as one chunk rather than three individual units. This research can be applied to future research by investigating if using chunking technique for exam revision can aid better recall thus better exam results. For example teachers could hold revision session’s using call cards which are chunked into small amounts of detail for the student to remember. They can then test to see if students with revision aids did better than those without.

Lost Foam Casting Essays

Lost Foam Casting Essays Lost Foam Casting Paper Lost Foam Casting Paper LOST FOAM CASTING ABSTRACT: The Report presents some theoretical and practical aspects regarding the casting of alloys in lost foam moulds. The stages of the procedure, the economic benefits and several ecological aspects are synthetically presented. KEY WORDS: casting, alloys, lost foam process, Expanded polystyrene Introduction The lost foam casting process offers several advantages over conventional sand casting processes, such as simplified production techniques and reduced environmental waste due to binder system emissions and sand disposal. The process is well-suited for castings with complex geometries, tight tolerances, and smooth as-cast surface finish requirements. When the castings are designed to fully exploit these advantages, cleaning and machining times are dramatically reduced if not completely eliminated. Therefore, the lost foam casting process is viewed as a value-added process rather than a substitute for sand casting. Lost foam castings are produced by pouring molten metal into a foam pattern contained in a flask filled with loose sand that is compacted through vibration. Generally speaking, a foam pattern is coated with a refractory slurry and dried before being placed in the flask and surrounded by large grain fineness sand. The foam pattern degrades immediately after molten metal is introduced, leaving a casting that duplicates all features of the foam pattern. The degradation products are vented into the loose sand. In lost foam casting process, mold filling, thermal transport, and solidification are strongly influenced by the foam pattern degradation. There are three phenomena which are inherent in lost foam casting process: slow molten metal flow, reducing atmosphere, and degradation products. The first and second phenomena help reduce oxides or slag defects. The last one, however, may become casting defects if they remain in the cast parts. To improve lost foam casting design, it is ssential to understand the interactions between the foam pattern and molten metal as well as the displacement of degradation products. History The first patent for an evaporative-pattern casting process was filed in April 1956, by H. F. Shroyer. He patented the use of foam patterns embedded in traditional green sand for metal casting. In his patent, a pattern was machined from a block of expanded polystyrene (EPS), and supported by bonded sand during pouring . This process is now known as the full mold process. In 1964, M. C. Flemmings used unbonded sand for the process. The first North American foundry to use evaporative-pattern casting was the Robinson Foundry at Alexander City, Alabama. General motors first product using these processes was the 4. 3L, V-6 diesel cylinder head, which were made in 1981 at Massena, New York. A study found in 1997 that evaporative-pattern casting processes accounted for approximately 140,000 tons of aluminum casting in the United States. The same survey forecast that evaporative-pattern casting processes would account for 29% of the aluminum, and 14% of the ferrous casting markets in the near future.

The Lost Foam casting process originated in 1958 when H. F. Shroyer was granted a patent for a cavity-less casting method, using a polystyrene foam pattern embedded in traditional green sand. The polystyrene foam pattern left in the sand is decomposed by the poured molten metal. The metal replaces the foam pattern, exactly duplicating all of the features of the original pattern. Like other investment casting methods, this requires that a pattern be produced for every casting poured because it is evaporated (â€Å"lost†) in the process. Schematic of lost for casting Process The essential steps of the lost foam casting procedure are: 1) The execution of patterns, 2) Execution of moulds 3) casting the alloy. Execution of Patterns: A pattern is made from  polystyrene foam (Expanded Polysterene), which can be done many different. What is Expanded Polystyrene? Expanded Polystyrene in its broadest sense is a rigid cellular plastic which is found in a multitude of shapes and applications. Raw Material Manufacturing: Expanded polystyrene (EPS) is the most commonly used foam pattern, it can be produced by bead pre-expansion into polystyrene (PS) beads that are ready for moulding. PS precursors are formed from ethyl benzene through an aluminum catalyst with benzene and ethylene obtained from crude oil and natural gas [Shivkumar, 1994]. Ethyl benzene is then converted to styrene at high temperature with nitrogen gas and iron catalysts. It forms polystyrene when exposed to a peroxide catalyst and polymerized in a water solution [Goria et al. , 1986]. These unexpanded beads have a density of 600 g/l (38 pounds per cubic feet (pcf)) and they are expanded 20~50 times with heat at 100 oC until the desired density is reached [Kanicki, 1985]. Polystyrene (PS) MOLECULAR FORMULA: The C=C double bond in each monomer is transformed into a C-C single bond in the polymer. | Properties: ease of forming, clarity, low heat transfer, good thermal insulation. Density: 1. 03-1. 06 g/ccStatistic: In 1999 PS usage as a plastic bottle resin was essentially nil. | Description: Polystyrene can be made into rigid or foamed products. It has a relatively low melting point. Packaging applications: Plates, cups, cutlery, meat trays, egg cartons, carry-out containers, aspirin bottles, compact disc jackets Recycled products: Thermal insulation, light switch plates, egg cartons, vents, rulers, foam packing, carry-out containers Raw Material Manufacturing: Expanded Polystyrene (foam)  is obtained from expandable polystyrene (beads), which is a rigid cellular plastic which contains an expansion agent. Expandable polystyrene is therefore obtained from oil as can be seen from the diagram. The EPS Manufacturing Process is inextricably linked with the process described in the last section, which brought us from the oil well to expandable polystyrene, now we will see what happens in the transformation process that leads us to Expanded Polystyrene foam parts. We have seen that the raw material is obtained through a chemical process. The next process involves the use of physics and the conversion process is carried out in three stages. 1st stage   PRE-EXPANSION: The raw material (beads)  is heated in special machines called pre-expanders with steam at temperatures of approximately 215-f. The density of the material falls from 40lbs/cu ft to values of usually between 1 ~ 2lbs/cu ft. During the process of pre-expansion the raw materials hard beads turns into cellular (foam) plastic beads with small closed cells that hold air in their interior. 2nd stage   INTERMEDIATE MATURING AND STABILIZATION: On cooling, the recently expanded particles form a vacuum in their interior and this must be compensated for by air diffusion. This is how the beads achieve greater mechanical elasticity and improve expansion capacity, something very useful in the following transformation stage. This process is carried out during the materials intermediate maturing in aerated silos or mesh bags. The beads are dried at the same time. 3rd stage   EXPANSION AND FINAL MOLDING: During this stage the stabilized pre-expanded beads are transported to molds where they are again subjected to steam so that the beads bind together. In this way large blocks are obtained block molding   (that are later sectioned to the required shape like boards, panels, cylinders etc. ) or products in their final finished shape shape molding. Execution of moulds and casting alloy The basic steps to the process include: A foam pattern and gating system are made using a foam molding press * The foam pattern and the gating system are glued together to form a cluster of patterns * The cluster is coated with a permeable refractory coating and dried unde r controlled conditions * The dried, coated cluster is invested in a foundry flask with loose, unbonded sand that is vibrated to provide tight compaction * The molten metal is poured on to the top of the gating system which directs the metal throughout the cluster and replaces the foam gating and patterns * The remaining operations such as, shakeout, cut-off, grinding, heat treat, etc. are straightforward and similar to other casting processes. The series and major steps in lost foam casting (LFC) What metals can be poured in the Lost Foam process? Generally, all ferrous and non-ferrous materials can be successfully cast using the Lost Foam process. Because the foam pattern and gating system must be decomposed to produce a casting, metal pouring temperatures above 1000 °F are usually required. Lower temperature metals can be poured, but part size is limited. In addition, very low carbon ferrous castings will require special processing. What size range of parts can be produced by the Lost Foam process? Lost Foam castings can be produced in most all metals from a fraction of a pound up to thousands of pounds. Slightly more advanced techniques are used for very large castings. What type of tooling is required and at what cost? Typically, tooling is composed of a split-cavity machined aluminum die that is the negative mold from which the foam pattern is produced. The tooling is highly specialized and must be constructed by experienced tooling manufacturers familiar with the requirements of the foam molders and foundries. Most tooling for Lost Foam patterns will compare favorably with permanent and die cast tooling. Prototype and simple tools may be in the $3000-5000 range while high-end tooling for complex or very large parts can be in the several hundred thousand dollar range. As a result of the materials used and the process stresses, Lost Foam tools can be expected to have 3 to 4 times the cycle life of permanent mold or die casting tools. What lead times can be expected when ordering a Lost Foam casting? As with all processes, lead times vary greatly depending on part complexity. Generally, 8 to 16 weeks is typical for completed tooling and first castings produced. After casting approval, 6 to 12 weeks is typical for production run startup. Rapid prototyping methods can produce castings in as little as 2 to 3 weeks. What size range of parts can be produced by the Lost Foam process? Lost Foam castings can be produced in most all metals from a fraction of a pound up to thousands of pounds. Slightly more advanced echniques are used for very large castings. What is the cost of using the Lost Foam process? Lost Foam castings are generally more expensive than forged parts, or parts made by other casting processes. The value inherent in the Lost Foam process v ersus other processes is seen in tighter tolerances, weight reduction and as-cast features which all results in less machining and cleanup time. Many castings that require milling, turning, drilling and grinding can be made in the Lost Foam process with only . 020† . 030† of machine stock. It is imperative that the features to be cast are discussed by all parties to determine the net finished product cost. What quantities need to be made to make the Lost Foam process practical? The answer, simply, is not as many as you would think. Tooling amortization is a key factor in this determination. Potential overall savings for your application will aid in your decision. Generally, 500-1000 pieces per year is the minimum production run to be economical. Prototyping runs, however, may be as few as 3-5 pieces for Fabricated Foam patterns or 20-100 pieces for Quick-Cut CNC machined aluminum tooling. Application Lost foam casting  is used mostly for automotive applications. Cast iron, aluminum alloys, steels, nickel and in some cases stainless steel and copper alloys are cast in this process. The flexibility of LFC is useful in making complicated casting assemblies for automotive and other metal cast like cylinder heads, weldments, pump housing, Manifolds for automobile, machine bases, automobiles of product produce from lost foam casting glmmarine. com/ManifoldArticle. html Superior Marine Manifolds Agricultural Equipment Part / Farm Machinery Part Product Description Detail Feature: Product Name: Agricultural equipment part / Farm machinery part   Materials: Grey iron, Ductile Iron, High Chrome iron, resistent ironcarbon steels, alloy steels, stainless steels, High Manganese steel   Items: FOB NingBo or Shanghai Place of Origin: Ningbo, China Software for specification drawings: PDF, Auto CAD, Solid work, JPG, ProE   Main production equipments: Wax injection, CNC-machine, machine-center, Heat treatment Furnace lost foam casting for yacht gas piping Specifications 1). lost foam casting 2). reliable product quality 3). on time delivery 4). excellent after-sale service 5). 3D design It is designed for the yacht or the ships gas exhaust piping.

Complex castings, particularly internal sections, which require high dimensional accuracy and have thin sections, can be produced very cost effectively in comparison with to conventional sand moulding processes. * Fettling and machining is minimized due to high dimensional accuracy and the absence of parting lines or core fins. * The shakeout process is simplified and does not require the heavy machinery required for bonded sand systems. * High levels of sand reuse are possible. As little as 1-2% of the sand is lost as a result of spills. Periodically a portion of sand may need to be removed or reclaimed to avoid the build-up of styrene. * Complex components can be formed where other casting processes would require multiple components to be assembled. Excellent dimensional tolerances for precision casting. * Lower production cost than traditional Green Sand casting. * Castings can be made from 1 pound up to thousands of pounds with no size limitations. * Lost Foam is an environmental ly friendly process. * The sand is un-bonded and can be recovered and re-used at a low cost. * There is lower capital investment. Disadvantages * pattern costs can be high for low volume application * patterns are easily damaged or distorted due to their low strength. If a die is used to create the patterns there is a large initial cost * The pattern coating process is time-consuming, and pattern handling requires great care. Good process control is required as a scrapped casting means replacement not only of the mold but the pattern as well. What type of tooling is required and at what cost? Typically, tooling is composed of a split-cavity machined aluminum die that is the negative mold from which the foam pattern is produced. The tooling is highly specialized and must be constructed by experienced tooling manufacturers familiar with the requirements of the foam molders and foundries. Most tooling for Lost Foam patterns will compare favorably with permanent and die cast tooling. Pr ototype and simple tools may be in the $3000-5000 range while high-end tooling for complex or very large parts can be in the several hundred thousand dollar range. As a result of the materials used and the process stresses, Lost Foam tools can be expected to have 3 to 4 times the cycle life of permanent mold or die casting tools. What â€Å"as-cast† tolerances can be expected? Typically, a linear tolerance of +/-. 005 inches/inch is standard for the Lost Foam process. This tolerance will vary depending on part size, complexity and geometry. Subsequent straightening or coining procedures will often enable even tighter tolerances to be held on critical dimensions. A targeted effort between the foam pattern producer, the casting producer and the casting user will often result in a Lost Foam casting that substantially reduces or completely eliminates previous machining requirements. Diameter Tolerance 0-1 in. [ or -]0. 007 in. 1-3 in. [ or -]0. 15 in. 3-6 in. [ or -]0. 025 in. In the case of diameters split by glue lines, 0. 005-0. 010 in. should be added dependent on foam size. Linear Tolerance 0-2 in. [ or -]0. 005-0. 10 in. 2-5 in. [ or - ]0. 010-0. 20 in. 0-5 in. with glue lines [ or -]0. 025-0. 035 in. Flatness Tolerance Area 3 x 3 in. [ or -]0. 007 in. Area 10 x 10 in. [ or -]0. 015-0. 020 in. More than 10 in. [ or -]0. 030-0. 050 in. Flatness can be affected by the foam, foam geometry, molding cycle control and foam removal. True Position Tolerance 0-2 in. 0. 025 in. 2-4 in. 0. 030 in. 4-10 in. 0. 030-0. 60 in. 10 in. 0. 080 in. Limitations 1. For low volume applications, the pattern costs are relatively high, therefore in order to increase the substantial economic benefits and decrease the pattern costs, only bulk quantities should be produced. 2. Due to their low strength, the patterns are very easily damaged and/or distorted. 3. There is a very high initial cost if a die is used to create the patterns. 4. The coating process is very time consuming as the pattern handling requires great care. Design considerations: Ensure that there is adequate material: Insufficient material usually leads to incomplete castings in the manufacturing of parts. It is important to calculate the volume of all areas f the casting while also accounting for shrinkage. Consider the Superheat: Superheat is the temperature difference between the metal at pouring and freezing. An increase in the superheat can increase the fluidity of the material for the casting, which can assist with its flow into the mold. Insulate Risers: The riser should be the last to solidify because it is the reservoir of molten material for the casting. Therefore insulating the top will greatly reduce cooling in the risers from the steep temperature gradient between the liquid metal of the casting, and the room temperature air. Consider V/A Ratios: V/A ratio represents the volume to surface area ratio. In casting, sections with low volume to surface area will solidify faster than sections with higher volume to surface area. It is therefore important to consider the V/A ratios in order to avoid premature solidification of the casting and the formation of vacancies. Heat Masses: Sections of the casting with low V/A ratios should be located further away from the risers as this will ensure a smooth solidification of the casting. It is important to avoid large heat masses in locations distant to risers. Sections of the Casting: A heavy section should not be fed through a lighter one. In the manufacturing process, the flow of material is very important. Prevent Planes of Weakness: After the solidifications of castings, columnar grain structures pointing toward the center develop in the material. This causes the sharp corners in the casting to develop a plane of weakness. This is prevented by rounding the edges of sharp corners. Reduce Tubulence: Turbulence is bad because it traps gases in the casting material and causes mold erosion. It can be reduced by the design of a gating system that promotes a more laminar flow of the liquid metal. FUTURE EPF can safely be incinerated and will yield only carbon dioxide and water if the procedure is handled correctly, but the trend has been to recycle it wherever possible. EPF can be recycled into  concrete,  egg cartons, office products, foam insulation, and garbage cans. Unfortunately, only one percent of the 11 billion kilograms of EPF thrown away each year is being recycled. The National Polystyrene Recycling Company, which consists of seven major corporations, including Amoco, Dow, and Mobil, plans to increase this to 25 percent by 1995 by focusing on big users of EPF- fast food outlets and college dining establishments. Since the Montreal Protocol of 1988, new research has focused on ways to reduce CFC use, and on developing alternative blowing agents that will not harm the ozone layer. Recent developments include a process that uses pressurized carbon dioxide to produce smaller, more uniform cells. These in turn provide a foam that is stronger and smoother than earlier foams. All this will bring us an uns are U. S. Department of Energy and metal casting industry industries of the future (IOF), University of Alabama-Birmingham and over 30 universities and industry partners. This strategy has significantly improved the use of LFC in the past years. Emphasis is based on universities research with strong industry participation. The direct results of LFC researches are quickly applied by these positioned partner industries and results from the various applications are evaluated and analyzed. 2. Another strategy used is introducing hundreds of students to metal casting industries were they are well trained and becomes more innovative bringing latest technical knowledge and processes. this has tremendously improve state-of-the-heart technology in improving LFC in the past years. 3. Material(s) selection requires a specific type of manufacturing process(s) and different type(s) of casting techniques. The casting materials specific heat as well as that of the mold material will be influential in controlling the thermal gradients in the system. e. g. melts  fluidity and flow. A material high heat of fusion will take longer to solidify and may improve flow characteristics within the casting. 4. Gases being expelled by the material during solidification can be eliminated by a proper venting system in the mold. This can be planned out during the manufacturing design phase of the casting process. WAYS TO IMPROVE LOST FOAM CASTING 1. Development of computational fluid dynamics tool for modeling the blowing and steaming of expandable polystyrene (EPS) pattern for lost foam casting(mathematical tool). it allows analytical approach to systematically design EPS pattern molds that produces higher quality pattern with reduced lead-time and expense. arena-flow. com 2. Reduction of porosity and fold defects has improve production efficiency, mechanical properties and marketability of lost foam casting. 3. The combination of LFC with 3DP (three dimensional printing) to eliminate machining of mold contours and manual process of drilling and finishing steam holes, i. e. repeatedly printing thin layers of bonding materials on a thin layer of powder to build up a tool(mould) shape from computer-aided design(CAD) 4. Complex and detailed passages and other features are cast directly e. g. oil galleries, crank case ventilation channels, oil drain back passage, coolant passage etc are cast directly into cylinder blocks 5. The use of Flow Particle Image Analyzer to analyzed the wet slurry (prior to its application on the foam pattern) by measuring ceramic particle size and shape. 6. Single and multiple air gauge developed for rapid determination of pattern dimension 7. Compaction gauges were developed to measure sand density in cavities during pattern compaction 8. Distortion gauge to determine when and under what conditions pattern distortion occurs during compaction 9. Developed procedures to measure liquid absorption characteristics of liquid pattern pyrolisis 10. Developed instruments to measure gas permeability 11. X-ray radiography was developed to measure time of fill and also to inspect casting qualities and defects in LFC. Material selection is another way to improve the capability for example: * Certain materials react, (particularly in a molten state), a certain way with other materials they may encounter during the casting process. This should always be a consideration. For example liquid aluminum will react readily with iron. Iron ladles and surfaces contacting the molten aluminum can be covered with a spray-on ceramic coating to prevent this. * When selecting a specific type of manufacturing process, remember that certain materials are more applicable to different types of casting techniques than others. * The casting materials specific heat will as well as that of the mold material will be influential in controlling the thermal gradients in the system. Different materials will factor heavily on the melts  fluidity * A material high heat of fusion will take longer to solidify and may improve flow characteristics within the casting * When manufacturing a casting an alloy that freezes over a tempe rature range problems may occur due to the solid phase interfering with the liquid phase -both of which will be present within the temperature range. To help reduce this problem an alloy with a shorter solidification temperature range may be selected to manufacture the casting with. Or select a mold material with a high thermal conductivity, which could reduce the time spent in this range by increasing the cooling rate. Conclusion using the method of casting by lost foam patterns, we can obtain pieces for industry and ornamental elements / applied art, with complex layouts and different sizes, without the danger of offsetting * using the method of casting by lost foam patterns we can obtain pieces with weights between a few kilograms and tenths of tones, with wall’s width between 1 mm and 50 mm, made of different alloys: ferrous (cast iron and steel) and non ferrous (basic alloys of Al, Cu, Mg); * using the method of casting by lost foam patterns we can obtain pieces with a l ow consumption of materials and energy; * The method of casting by lost foam patterns can be used also for: structural changes and superficial alloying of the pieces; obtaining composite materials with powders insertion and the guidance of hardening by using some active powders, internal coolers or exterior coatings. The gases resulted from the thermal destruction of the polystyrene are toxic for the human being and can generate negative effects on the environment, aspect which imposes the obligation of maintaining under control both the evacuation in the working environment as well as the evacuation in the atmosphere.
