Apollo moon landing was a hoax Essay Example for Free

Apollo lunation set down was a hoax EssayThe US stagnate landing program was started by John F. Kennedy in response to the Soviet Unions early successes in space exploration, just in case the world resolute that Communism was the way to go. The Moon landing hoax refers to the belief of a small, but persistent, percentage of people who think that the Apollo Moon landings of the late 60s and early 70s were propaganda films produced by NASA to embarrass the USSR in the cold war. First I will start talking about the central asseverates and evidence that proof why Apollo moon landing wasnt a hoax. in that location is quite a lot of evidence to proof that Apollo moon landing wasnt a hoax. There is a ample quantity of lunar surface samples for example rocks that was brought back by the Apollo missions. These samples argon the same than those brought back by Soviet Union missions and they arent alike whatever rock on earth. Many international scientists have spent their entire c areers studying these things and If they prove that this rocks didnt come from the Moon, it would degrade their scientist names in an instant.There is a large number of p gamyographs and videos taken on the Moon, that shows that they really went to the moon. Close up footage of dust being kicked up by the astronauts on the Moon or raised by the wheels of the lunar shows that the dust fell parabolically, as expected in a vacuum. If the landing footage were shot on Earth, the dust would float round in the air before falling to the ground. There is not only photograph to proof Apollo moon landing there is also people to assure the evidence. People who made the journey are still alive and able to testify the fact along with the thousands of people who worked on the project. Some people claim the use of reflectors. These reflectors have been used extensively by other researchers. The use of reflector caused many theorists to believe that the moon landing was faked. There are groups tha t comport that NASA went to the moon, however, the things they saw were so incredible they had to hide the evidence of aliens. On the other hand there are Conspiracy theories that reveal that the Apollo moon landing couldnt be possible.Members of the Hare Krishna movement refuse to accept the landings, because it would contradict what their holy texts say about the Moon (for example, that it is further away than the Sun, surrounded by arouse and ice) others believed. Others said that the astronautsonly went into Earth orbit. This is usually connected to the claim that the space was filled with deadly radiation that could kill astronauts. People believed that the earlier landings were faked, but that NASA lastly managed to get there some time in the 70s. They state that the United States faked reports of the original landing to threat the Soviet Unions attempts during the Space Race of the Cold War. asunder from some junto theories there is also evidence that shows that Apollo mo on landing was a hoax. I will analyze some of the evidence the technology, the flag, the transmission and in conclusion the environment. Bart Sibrel said that the level of United States and USSR space technology as evidence that the Moon landings could not have happened.For much of the early stages of the Space Race, the USSR was forrader of the United States, yet in the end, the USSR was never able to fly a craft to the Moon, It is argued that, because the USSR was unable to do this, the United States should have also been unable to widen the technology to do so. Another part of the moon landing hoax theory deals with the American flag. The picture that was sent back showed this flag moving as in a wind. Some believers in the moon-landing hoax feel that this was proof that this picture had been taken on earth and not the result of a moon landing. The fact that the flag moves in the wind when there is no wind on the moon could lend some degree of credibility to the belief that th is was a hoax. There should have been more than a two-second delay in communications between Earth and the Moon because of the distance between the earth and moon.Typical delays in communication were about 0.5 seconds. Scientists claim that the delays were only half a second are untrue, as examination of the original recordings shows. Also, there should not be a constant time delay between every response, as the conversation is being recorded at one end Mission maneuver. Responses from Mission Control could be heard without any delay, as the recording is being made at the same time that Houston receives the transmission from the Moon. The Moons surface during the daytime is so hot that a filming camera would have melted, as there is no atmosphere to efficiently protect the lunar surface from heat heat on the moon would affect devices such as cameras. The surface does get very hot at lunar noon every Apollo landing was made currently after lunar sunrise at the landing site.In concl usion given to the context of the moon landings and that of the Space Race with the Soviet Union, there are many, many reasons whypeople would prove that the landings were faked for a political and monetary gain, pure fame, and so on. There isnt a real proof bring out the landings by a first-hand knowledge, or evidence no only a photograph that could be fixed on a studio. If we assume a conspiracy exists, we need to know what it involves. Given the number of people that would need to be paid off to stay silent, the effort required to pull the attention everyplace the USSRs eyes, the ground based fakery rockets, launches, control rooms fakery such as moon rocks and the photography and video taken from the moon.

Physical therapy intervention with a stroke patient Essay Example for Free

Physical therapy intervention with a stroke patient EssayThe clinical licenseations of neurologic disease argon as varied as the disease processes themselves. Symptoms can be subtle or intense, fluctuating or permanent, an inconvenience or devastating. early clinical manifestation is Pain, it is considered an unpleasant sensory perception and emotional experience associated with actual or potential tissue damage or expound in terms of such damage. Pain is therefore considered multidimensional and entirely subjective.Seizures are the result of abnormal paroxysmal discharges in the cerebral cortex, which then manifest as an alteration in sensation, behavior, movement, perception, or consciousness. The alteration may be short, as in a blank stare lasting only a second, or of longer duration, such as tonic- clonic grand mal seizure that can last several minutes. Dizziness, an abnormal sensation of imbalance or movement. It is pretty common in the elderly and one of the most comm on complaints encountered by health professionals.Visual Disturbances, visual defects that cause people to seek health business concern can range from the decreased visual acuity associated with aging to sudden blindness. Weakness, specifically muscle failing is a common manifestation of CVA. Weakness a great deal co exists with other symptoms of disease and can affect a variety of muscles, causing a wide range of disability. Weakness can be sudden and permanent, a sin stroke, or progressive, as in many neuromuscular diseases. Abnormal sensation, numbness, abnormal sensation, or loss of sensation is a manifestation of cerebrovascular accident. Altered sensation can affect small or large areas of the body. It is frequently associated with weakness or pain and is potentially disabling. Both numbness and weakness can significantly affect balance and coordination. Assessment of cortical motor integration is carried out by asking the patient to perform a delicate act like asking a pa tient to throw a ball, move a chair. Successful performance requires the ability to understand the activity desire and normal motor medium. Failure signals cerebral dysfunction. Examining the Motor System, a thorough examination of the motor system includes an assessment of the muscle size, tone and strength, coordination, and balance. The patient is instructed to qualifying across the room while the inspector observes posture and gait. The muscles are inspected, and palpated if necessary, for their size and symmetry. Resistance and Abnormalities are documented after. Assessing the patients ability to flex or extend the extremities against resistance test muscle strength. Once the leg is straightened, it is exceedingly difficult for the examiner to flex the knee.Conversely, if the knee of the patient is flexed and is asked to straighten the leg against resistance, a more subtle disability can be elicited. For example, the right upper extremity is compared to the left upper extre mity. In this way, subtle differences in muscle strength can be more easily detected and accurately described. Coordination in the hands and upper extremities is well-tried by having the patient perform rapid, alternating movements and point-to-point testing. First the patient is instructed to pat his or her thigh as fast as possible with each hand separately. Then the patient is instructed to alternately pronate and supinate the hand as rapidly as possible. The n lastly, the patient is asked to touch each of the fingers with the thumb in a consecutive motion.Speed, symmetry, and degree of difficulty are noted. Coordination in the lower extremities is tested by having the patient run the heel down the anterior surface of the tibia of the other leg. Each leg is tested in turn. The motor reflexes are involuntary contractions of muscles or muscle groups in response to abrupt stretching near the site of the muscles insertion.The brawn is struck directly with a reflex hammer or indirec tly by striking the examiners thumb, which is placed firmly against the tendon. Testing these reflexes enables the examiner to assess involuntary reflex arcs that depend on the presence of afferent stretch receptors, spinal synapses, efferent motor fibers, and a variety of modifying influences from higher levels. commonalty reflexes that maybe tested include the deep tendon reflexes like biceps, brachioradialis, triceps, patellar, and ankle reflexes and superficial or cutaneous reflexes like abdominal reflexes and plantar or Babinski response.ReferencesBrunner, K., Suddarith, L.

Audi Marketing Mix Analysis

Audi Marketing Mix AnalysisThe Audi history begins with a man called August Horch, and in 1899, he established the Comp all HORCH CO. He invented his first motorcar in 1901. nevertheless in 1909 Mr. Horch leaves his familiarity and founded an different company called Audi. Audi is the Latin translation for Horch and he took that piss. In 1910, the grass AUDI Automobilwerke GmbH was registered. In 1931, the AUTO UNION was founded some members were DKW, HORCH, WANDERER and AUDI. Moreover, the impudent companies insignia to show the union of the quaternity companies was the now familiar 4 rings, that what still employ by Audi today. After the 2nd world war, in that place were a turn a profit many an(prenominal) cars produced, the most important for them were the DKW Munga, a four-wheel jeep with 3-cylinder 2-stroke engine. Invented in 1956 for the German military, there have produced 250 cars for scrutiny purposes. And these cars made a trip around the world and drove more than 240 000 km in addition without major occupations. This was the beginning of the later pattern called Quattro and it had nearly 57 000 Mungaswere built until 1968. In the fol humbleding years, they have many different engine- and car types were invented and produced in large amounts. There overly improving, rallying and testing the first real ur-quattro with the peeled coupe body was build in 1980. And the power has been raised to 200hp in the testing time, and most of the early(a) car manufacturing commercial enterprise did with a 2.2l engine.Audi, the core brand that the Audi has been foc exploitation by the Audi Group in adopting its Strategy 2020 on the challenges of the incoming. The mission We becharm customers worldwide was explored in spaciouser depth during 2011 where the dodge took on firmer contours. Heightened environmental aw areness, growing uncertainty about the future availability of fossil fuels and increasing urbanization are the results of giving mor e weight to newborn issues that have emerged.The Mission of this company is We delight customers worldwide. The Audi brands harvest-homes are famous of the brand values sportiness, modernism and sophistication. The brand with the four rings aims to suggest customer delight in many other ways and thus can lead to building technologically advanced vehicles. The mission statement which is We delight customers worldwide plays a main role on the path to becoming the leading first-class brand. The Audi brand has well-defined its understanding of customer delight in greater expand in the following four areas of action. That are We define innovation, We create experiences , We live responsibility and We shape Audi.In this company there have three objectives. first base is to create impact and drive awareness of Audi Q5 launch. Second is demonstrating Audis core value proposition of Progressive Performance. And then last is communicate Audis prestige offering. Those three objectives is w hat Audi company execution in this few years. On the other hand, in this few year the Audi Companys target mart are predominantly males amidst 40-50 years old, espouse with a household inejaculate between $137K $265K. And women who are a key influencer in the purchase process of the Q5.Chapter 2 Analysis of Marketing Mix Strategies2.1 PRODUCT STRATEGIES2.1.1 harvesting ClassificationAudi car are known as the wants or desires that less frequently bought by the con nerveer so Audi car is classified as luxury proceeds in the category of consumer harvest-tide. Consumer product is defined as the products and function bought by final consumers for personalized consumption.Audi car is known as one of the well-known car that less frequently bought by the consumers due to the toll is expensive which is within the black market of RM 179,900 to RM 1250,000. Therefore, consumers leave behind do a survey and castning before they truly want to buy it. Wisely consumers testament co llect a lot of information that relevant to Audi and do worth comparison with other car in the market with their main competitors which are BMW and Mercedes-Benz.Furthermore, Audi car is also selling in high price that seldom consumed by the consumers. It is a branded product that having hole advertisement in magazines, television and personal selling by reseller and producer in frame to convince consumers to buy it and remind the consumer about their product in the market.BrandingBranding plays an important role in identifying the seller and buyers of Audi. It differentiates them from their competitors. Audi is design with four interlinked rings that represent one of Germanys oldest automobile manufacturers. The first ring from the left over(p) represents Audi, the second represents DKW, third is Horch, and the last ring is Wanderer.Its similarity to the Olympic rings caused the International Olympic Committee to indict Audi in International Trademark appeal in 1995. In additi on, this is a simple logo and made a lot of raft to recognize and remember. With the current type of branding, it had brought the product identification to the consumers with its unmatched design. This will not only ease the consumers to differentiate their product but also help to segment markets.In addition, it also symbolized the inseparable unity of the four founder-companies which are Audi, DKW, Horch and Wanderer. Each of the four companies was allocated a specific market segment within their group. DKW was responsibility for motorcycles and small cars. Wanderer built midsize cars and Audi manufactured cars in the tremendous midsize class. Horch produced deluxe top-of-the-range automobiles. Besides, it extends product quality and consistency as the consumers know that they will get the identical eudaemonia, feature and quality each time they bought the Audi product.LabelingLabeling are using in describing several things of the product. Audi car will offer an instruction book for every buyer. This instruction book encompasses the information of the brand, details about the car, and instruction in how to use and control the car.PackagingAlmost all of the products in the market needed packaging. Packaging is essential in term to market the brand and nurse the products to ensure the product is safety. Audi car usually covers the seating of new car with plastic to prevent dust will stain the cushion. Furthermore, a protective hold will cover on the scene of indicator. This is to prevent the scene to be scratched. Thus, this can protect the product safety.Product Support ServicesProduct patronize services are to enhance customer service and satisfaction by assess the value of current services and obtain idea for adding new services to delight the customers. For a new or potential customer, Audi will offer free test drive for them. This is to give away sure the customer satisfy with their product. They also provide after-sale services included 2 years warranty and 6 months of installment completely free after customer purchase the car to make sure the customer not just satisfy and also happy when use their product because their product performance is greater than the consumer expectation. There are many Service Centers of Audi Company in Malaysia such as Audi Centre Glenmarie, Audi Juru, Audi Johor Bahruand so on. These services will add up the customers satisfaction with the brand of Audi and increase in brand positioning.2.1.2 Major brand strategy decisionBrand PositioningThe Audi slogan is VorsprungdurchTechnik, which essence the Progress through Technology. Audi is using the German language tagline as many other country used it such as European countries and United Kingdom. Recently, Audi had updated the slogan into Truth in Engineering. Audi is place in the product benefit because Audi automobiles want to provide the most authentic, truthful driving experience in the luxury segment through their slogan.Brand Name Selection The company name is based on the surname of the founder August Horch, the name itself an English similar with the English word hark, meaning listen.Audi is known as the good brand name selection because it can translate easily into foreign languages and distinctive from other brands. The brand name also easy to pronounce, recognize and remember in the world.Brand SponsorshipAudi is consider as manufacturers brands that also call national brands in the brand sponsorship. This is because Audi sell their output under their own manufacturers brand names. For fountful, the spare separate of all the Audi car can obtain it from German Motors in Petaling Jaya, Malaysia.Brand DevelopmentWe consider Audi company is using line extension strategy which means existing product and brand for the brand development. Line extension occur when a company introduced additional product in a given product category under the same brand name into the new forms, colours, sizes, ingredients, or flavour of a n existing product category. For example, existing Audi S1 is upgrade to Audi S2 and Audi S3 which have a fail and advanced performance. Audi S3 thats been tuned by TS Racing. This race car that not only packs an aerodynamic kit, but it was tuned specifically for racing purposes. The kit includes a front splitter, modified bumpers, a rear diffuser, extended wheel arches, and a roof-mounted scoop.2.2 PRICING STRATEGYNarrowly, price is the amount of money supercharged for a product or service. Broadly, price is the sum of all the values that consumers exchange for the benefits of having or using the product or service.2.2.1 Factors affecting determine decisionsAudi is using greet- based pricing method. Audi added a standard paper to the cost of the product. It is a simplify pricing, which is based on the cost. It is also fairer to both sellers and buyers as the price set is reasonable.Audi is under oligopolistic competition but not noncompetitive competition because there are on ly few companies those producing automobiles such as Mercedes Benz, Porsche, and BMW in Germany. Audi car is a differentiated product. Customers can easily differentiate Audi from the other brands. This is because of the unique logo of Audi which in four rings. The high quality products produced by Audi have developed a very clear image of technology in the minds of their target customers. Besides, Oligopolistic competition market has high barriers to entry. Therefore, Audi is able to earn economic profit in both short run and long run. Audi is price churchman which has the power to set its own price. However, it has to be aware of the actions of the others because it is mutual interdependence. Audi shapes its policies with an eye to the policies of the competitors such as Mercedes Benz and BMW. Audi has to ob set the actions of them from time to time because the actions of Audis competitors will affect Audis profit. Audi spends a large amount of money in advertising to convince cu stomers.2.2.2 New Product pricing strategiesAudi practised market penetration pricing when the new product was introduced in the market. Market penetration pricing is a quick- entry price strategy that assumes low price will off high sales masses which will result in lowering costs. It set a low initial price which is lower than the eventual market price in order for the brand to penetrate the market quickly and deeply. By using this method, Audi expect to attract a large cast of buyers quickly to the new brand as the product demand is highly price elastic. It also assumed that the lowers price will win market share. Once the marker share is gained, the price of Audi will be raised.2.2.3 Product Mix Pricing StrategiesProduct line pricing is a pricing strategy used to sell different products in the same product range at different prices based on features or benefits. In another words, it is when a company must decide the price differences between the upgrade of the product or serv ice. Audi has different type of model of car.The purpose of using these strategies is to maximize the profit of the company. For example, there is a huge range price different between Audi S3 and Audi TT.2.2.4 Price Adjustment StrategiesDiscount and allowance pricing reduces the product prices to reward customers responses. Discount can be classified in to cash, quantity, practicable and seasonal whereas allowances can be divided into trade-in and also promotional. For example, the Audi buyers can get the spare part from Germany Motor located in Petaling Jaya that comes with rebates and warranties.Dynamic pricing is known as time-based pricing or third-degree price discrimination. It occurs when consumers are divided into two or more groups with separate demand curves, and different prices are charged to each group. When done successfully, price discrimination practices like this enables the firm to capture more consumer surplus and thus, increase the profit of a firm. Dynamic pric ing arrange the prices continually to meet the characteristics and needs of individual customers and situations. Wide range of goods would be priced according to what the market will bear. If the demands of Audi car increase, the price of it will decrease, vice versa.The positioning pricing has a different price for different location or sitting arrangement. Audi car will be priced higher in Malaysia due to the location and high government import taxes.2.3 PLACE STRATEGY2.3.1 Market Channels/ Distribution ChannelsMarket distribution channel is a trunk of market institutions that enhances the physical flow of goods and services, along with ownership title, from producer to consumer or business user.Audi is promoting their products by using indirect sales merchandising channel. Audi is performing as producer only so it needs other channels like retailers and interlocutors in order to facilitate the exchange process by cutting down the number of contacts necessary. The intermediari es will also help Audi to promote their products to the final consumers with the help of intermediary, Audi manage to focus on produce innovative products rather than busy on promoting their products.2.3.2 retail/ WholesalingAmong the sales channel, Audi is using wholesaler channel to promote their products to the consumers. Wholesaling is known as all activities involved in selling goods and services to those buying for resale or business use. Since Audi is the company that involve in manufacturing products only, so it needs to undergo wholesaling process to promote their products by using developing and spreading persuasive communications.Therefore, Audi has form a strong wholesaling base to promote to the final customers and it need to grasp the real issues facing the wholesalers in order to implement the appropriate growth measures. With the strong wholesaler channel, Audi will able to focus on their innovation for products to keep competing in such high competitive market since this market is known as oligopolistic competition.2.4 promotional material STRATEGIESAudi Company is playing its role very well in the marketing promotional activities through the concept of integrated marketing communications. Audi Company is using a multifaceted promotion mix as its tools to increase the sales of its car and also achieve a higher performance. Those promotional activities of Audi Company are attempt their best to attract consumers attention and to make communication with them in order to reach them in a coordinated manner through integrated marketing communication.2.4.1 Direct MarketingOne of the elements in Audi Companys integrated promotional mix is direct marketing. It is offering a very special surrounding for its consumers to make them tang good in all the way of purchasing their new expectative cars. After stepped in the Customer Center, consumers will be welcomed by Audi Companys staffs and they will consult with the consumer to plan their schedule for t he day according to the objective they want to do. The schedule will be included a highlight activities, factory tour. The tour guide will show them how to produce the Audi Cars by using advance technology and accuracy workmanship way. Another highlight activity is visit to Audi shop and Audi museum shop. Audi shop stocks top-quality branded goods and up market lifestyle articles. In the Audi museum shop you are able to browse all the attractive tradition collection and a range of model historical cars are stored in it. At the end of the day that is the moment of the consumers to pick up their new car.2.4.2 Sales PromotionThere is a sales promotion conducted by Audi Company is called as Happy Anniversary and Happy Oktoberfest. This program is available for all the range of the Audi owners. To let more consumers sexual union for this program, Audi Company has provided all the styles, sophistication and performance of its cars in the exceptional prices. Furthermore, consumers also a ble to test-drive an Audi of their choice to discover which Audi are suitable for them.2.4.3 commonplace RelationsPublic relations refer to a firms communications and relationships with all types of its customers, such as publics. A very good news which is bring from Audi Company is that Audi will organizes the INI and HIN events, which serve as an education forum for everyone. And the INI.JUGEND.KOLLEG and the HIN.JUGEND.KOLLEG is just focus on the youth which are talented and interested in the promotion of technologies. During the series of the events, those participants will gain an opportunity to discuss and obtain some information about the current social and technical topics. A clear and accessible of the knowledge will be brought by a team of well-known speakers from Audi partner universities. With it, Audi Company is able to get more employed with young person talent. At the same times, it can gain a good image from its customers and stronger its Brand Name throughout the country or the world.2.4.4 Product PlacementAnother promotional mix element using by Audi Company is product placement. It is a non-personal selling marketing strategy. This approach is not only a lower cost-spending but also a very efficient way to gain more patron exposure to the users. Recently, Audi Company is using this approach by launching a free iPhone game which is called A4 effort Challenge 2.0. By choosing iPhone to expend Audi Companys customer flows as iPhone has gain a high performance of sales in the market segmentations from upper-upper to upper-lower. Audi Company is just a newest brand in using this non-traditional selling method in order to extend sales and to draw in more future clients as well.2.4.5 ordained Web SiteOn the other hand, it is a new trend that all companies will use advance technology to connect with their existing or incoming customers like social wed site or their own official web site. Same as other company does, Audi Company also having their own official web site which is http//www.audi.com/com/brand/en.html.

If consumers are wish to buy a new Audi, there is a fast and convenient way to check in the website, it has uploaded a list of details for all types of the Audi.Chapter 3 Analysis of Market Opportunities3.1 Technological OpportunitiesOne such opportunity in the future was the concept of a crossbred car that was first introduced in the 90s by Toyota. It would be a great technological opportunity for Audi to explore this as it would be perceived as a core segment of the automotive market of the future. The meaning of hybrid car, as quoted by Jeffrey Orloff (2007), is a vehicle that uses an on-board rechargeable energy storage system (RESS) and a fuel based power reference work for vehicle propulsion. These vehicles useless fuel than their counterparts and produce fewer emissions. Hybrid vehicles recharge their batteries by capturing kinetic energy through regenerative braking. Some hybrids use the combustion engine to generate electricity by spinning a generator to either recharge the battery or directly feed power to an electric motor that drives the vehicle. This takes place when cruising or in other situations where just light thrust is needed.Besides technology, several other environmental factors will also be discussed on how it presented such an opportunity for Audi AG and on how Audi could affect those environment.Although there is now in existence of many hybrid cars that are successful like Prius or Tesla, but none has dared to produce an elite and luxurious hybrid car which is currently being developed by Audi AG. Such an innovation could help Audi to dominate the automotive market for the next 25 years as quoted by the company because it would give them a great competitive edge. So far, Audi has developed 3 hybrid conc ept car which are Audi e-tron, Audi e-tronSpyder and Audi A8 Hybrid. Each of those cars are being researched independently in several workshops that follows on the new hybrid technologies like full hybrid, plug-in hybrid and parallel hybrid respectively. Besides, Audi also monitors all other innovation for a competitive advantage for example new alternative fuels called cellulosic ethanol for the hybrids or even Quattro drive system in correspondent to hybrid technology. With all technology combined and utilized with supreme effectiveness, it helps Audi to address not only the social concerns but also the economic concerns in the market environment.Focusing on Audi, their hybrid concept cars in the future market is able rival all luxurious sports car and luxury cars existed in the market now.Audi will embrace this opportunity and continue to advance in it technologically by making better hybrid cars and would eventually help pave the way for a more advanced environmentally friendly technology. As quoted in a CNN article by Phil OSullivan (2004), In the future we see this (hybrid cars) as an interim technology. In the future long-term fuel cells (whitethorn be) the best alternative.3.2 cordial Market OpportunitiesBesides, Audi also seeks opportunities in the social of the Asian market as Asian market is new and having vast development in automobile industry. The new emerging markets of Asian markets, especially China and India, are huge opportunities for Audi. By 2015, the Audi Indian car sale is estimated to be reaching more than $40 billion. In China figures indicate that sales will be in excess of 250,000 million vehicles in a similar period of time.The car sales in both of these countries are growing, as hoi polloi in these countries are getting wealthier and more discerning, they need more high-class brands such as Audi. According to MrMichealPerschke, Head, Audi India, the young generation, especially those who return from overseas, want more and the ir fathers are handling over the reins of business a lot faster, unlike the past, todays global Indians have different mindset. This attractive of mind- set has made India a potential market for Audi to expand their market, giving them the opportunity to be the leader in automobile industry.Another reason for Audi to accept China and India as their target market to expand their automobile industry China and India are countries which have the most population of people, hence, providing them a great source of labor force, and, the cost of production is much cheaper than in Europe countries because the cost of labor force is much cheaper. China and India have provided a great market opportunity for Audi, as the level of living in these countries is getting higher, thus increasing the demand of luxury cars, and also, people in these countries are able to provide Audi a great source of labor which could enhance the production.Chapter 4 Recommendations4.1The electro rheological (ER) flu ids used in the hybrid cars engine require high voltage to operate, that is, the equipment failure voltage of air is 3kV/mm. Audi can modify the ER fluid, by using different combination of electrodes which can reduce the voltage requirement of ER fluidto function. Suspension, which particles may tend to clump or settle, is also one of the major problems of using ER fluid in hybrid vehicles. Audi can tackle this problem by matching the density of the solid and liquid particles in the components, to ensure the effectiveness of the operation. Or, Audi can use nanotechnology-the nanoparticles, which the particles are very tiny in size, hence, reducing the suspension. To outstrip the problem of settlement of particles in the engine, Audi can add lubricant to enhance to lubricity of the engine, which can help to discourage the gravitational settling and promote particle suspense. lubricating substance helps to reduce friction, thus, enhancing the smoothness of operation, modifying the viscosity and inhibiting wear, improving the problem of suspension.4.2Next, it could be considered a right choice for Audi to expand its production in China and India because the labour cost in those potentially developing countries is much lower compare to its original country. However, low labour cost might affect the production of the company. A low wage paid to a worker would discourage a worker to put in effort to do his part perfectly. Audi can prevent this problem by increasing the wages or maybe give bonus to its workers who show their initiative to perform well in their job. It would not be a wise decision to have a great number of unskilled or unknowledgeable workers in an operation. Hence, it is suggested that, Audi chooses its crew wisely. Choose skilful and knowledgeable people to join the crew through a careful interview. Otherwise, provide training to those unskilled workers, or provide time- to- time skill- up courses and practical training, so that the workers are e quipped with relevant and up- to- date knowledge and skills. Besides, the Board of Directors has to do its duty checking the employees from time to time, distinguish the problem faced by employees and company, so that improvements can be made to ensure the quality of production is maintained.4.3There is a research shows that Asia countries, especially India is a highly potential developing country, as it attracts many planetary investors to invest in the country, meaning India has potential to become a high class country. This means that people in India will be able to owe luxury cars like Audi in future. However, presently the purchasing power for luxury goods of people in the country is still limited. Actually, Audi can refer to this present situation, come out with the concept of producing low cost cars or ordinary cars, to meet the needs of people in the countries. In this case, people with less income will be also able to own a car themselves. This will not only expand the mar ket and increase the income of the companyit is also beneficial to the people who are having a moderate income.Chapter 5 ConclusionIn my opinion, I calculate the current marketing mix which Audi has, is satisfactory to customer needs. Because for a new or potential customer, Audi will offer free test drive for the customer and to make sure there are satisfy with their product. On the other hand, customer also can easily to obtain latest information from the website. Because Audi Company having their own official web site which is www.audi.com/com/brand/en.html.In providing a wide range of products and with high quality, Audi has by far influenced most of the customers perception favorably towards its products. From time the company was created till now, the quality of the products that Audi offers is improving each year. But the well-known car that less frequently bought by the consumers because the price is too expensive which is within the range of RM 179,900 to RM 1250,000. The price will expensive is because Audi do price comparison with other car in the market with their main competitors which are BMW and Mercedes-Benz. And it is a branded product that having mass advertisement in magazines, television and personal selling by reseller and producer in order to convince consumers to buy it and remind the consumer about their product in the market.Even though the prices imposed by Audi seems to be fair with consideration of the quality of the products offered. The only problem is that, Audi has priced its products too expensively for a middle or lower class customer to bear up under to buy those products. Apart from that Audi has targeted its market mainly to urban customers as are the only customers who can afford such expensive products. In my opinion, I think Audi has to create also some of low end products with low prices which can be affordable to low income users.As I have mentioned above, In the case of place (distribution), Audi is using wholesaler channel to promote their products to the consumers. With the Audi have strong wholesaler channel, it will able to focus on their innovation for products to keep competing in such high competitive market since this market is known as oligopolistic competition.

Study Of Easyjet And The Airline Industry Tourism Essay

Study Of cleanjet And The Airline Industry Tourism Essay clear resiny Airline is integrity of lead inexpensive British get offline established in 1995. Easy putting surface has seen a rapid expansion, operating domestic and international service on viosterol drive shipway between Europe, North Africa and Asia. Its successful st straddlegies based on low-cost, no frills model which derive from the a concept that pick ups for short-haul stress transportation is wrong elastic. That means if the price of plane fines ar being reduced, more(prenominal) people willing fly.MicroeconomicsMajor determinants of demandThe demand for a particular cracking or service depends on a variety of factors. Key influences include the price of substitutes speci each(prenominal)y goods that be close substitutes, and the price of complements, the levels of consumer income, consumers expectation.()The availability of alternative modes of transportation for air locomotion atomic number 18 increasing, in particular ownership of automobile and the railway tuition. These close substitutes might be a threat a number of traditional air lane companies, dominating short journey sector (less than 3 hours). However, it is extremely difficult for rail transport to challenge a low-cost airline company like easyjet. For example, Euro stars cheapest tatters to capital of France is 149, whereas Easy Jets prices start from 17.99Airline costs per passenger, and rail fares, from BarcelonaPrice ElasticityAs demand law, when other factors on demand remain unchanged, a higher(prenominal)er(prenominal) price for a product will lead to a cut down quantity demanded. The price elasticity of demand measures the responsiveness, or sensitivity, of the demand for a good to changes in its price when other influences on demand are held constant. It is defined as the theatrical role change in quantity demanded resulting from a given dower change in price.For example, if a 1% increase in pr ice leads to a 1.5% drop in quantity demanded, the own-price elasticity of demand is 1.5. In this case, since the percentage fall in demand is greater than the percentage rise in price, total spending on the good will decline, and the demand for it is said to be elastic. If, on the other hand, a 1% price rise causes a smaller percentage decline in the quantity demanded, the own-price elasticity will be less than one, and demand is said to be inelastic.(.)The demand for air travel should be distinguished among markets for personal line of credit and leisure travel long-haul and short-haul travel and international and long-haul travel. Accordingly, to quiz the sensitivity of the demand for air travel to its price, separate estimates of the own-price elasticity of demand are gathered for each of these distinct markets.Since the alternative modes of transportation for long outdistance are not widely available, it is considered that the demand for air transport will be less elastic fo r long-haul flights than for short-haul flights. More everywhere, international travel tends to be spread over more time than domestic travel due to ball-shapedization, so that the plane ticket is more expensive than domestic tickets. globalization makes international travel especially business travel less sensitive to changes in ticket prices. On the other hand,travelers for leisure are more likely to postpone trips to specific locations in response to higher fares, or to shop around and looking for more affordable fares. Therefore, it is concluded that the demand for air transport for leisure travel will be more elastic than business travel.Price Elasticity of Supply and DemandThe relationship between demand and price of traveling by air can be both elastic and inelastic. To a large extent it depends on the type of customers traveling. For example a family planning a vacation that requires air travel, if the price of an airline ticket is extremely high, they are more likely decid e to delay the trip until the prices are lower. This shows that leisure air travel is considered elastic. However, if a business customer look ats to travel across the country by the next day, they will need a plane ticket regardless of the ticket price. For business travel, the price of airline would be considered inelastic because it is a necessity. The current market for business travel has a big part in the give and demand within the airline industry. More so in the economic downturn with the price of crude rapidly increasing, the cost of an airline ticket is then has risen and the demand for leisure travel has fallen. In addition, another reason for the decline in demand is that after 9/11 there has been outgrowth concern over in-flight safety. Another factor that influences the price of an airline ticket is the date that it is purchased. If there is anemergency, the customer may need to book a ticket on the day of travel or even purchases a ticket close to the departure t ime. The fact that there are still many unsold tickets is disregarded and the price will be higher.http//www.associatedcontent.com/article/1013568/the_economys_affect_on_the_airline.html?cat=27elastic.gif http//www.fin.gc.ca/consultresp/Airtravel/airtravstdy_1-eng.aspMarket structure of Airline industryThere are many factors wedged on the recent poor financial performance of traditional airlines, including the effects of 9/11, the global economic recession, the increasing growth of low cost airlines that make under a different business model, and the recent surge in burn down prices. As described below, several(prenominal) simultaneous factors are transforming the global airline industry. The growth of low-cost airlines The increasing growth of the market serving of low-cost, low cost fares during the last few years is one of the most significant trends in the industry, and has presented a considerable threat to the viability of network of traditional carriers. The response of th e traditional network airlines to the growing low cost airlines challenge will be vital to determining the future structure of the airline industry, both in the United States and in Europe.Competitive analysisThe most obvious competitive advantages Easy Jet had are delivering low-cost and maximizing margins. easyJet keeps costs low by cutting off the unnecessary costs and frills which is in traditional airlines. This is done in several major(ip) ways firstly, easy jet take advantage of the Internet to reduce distribution costs and then increase the example of the substantial assets and maximize utilization of each aircraft and therefore, significantly reduces the unit costSecondly, Easy Jet launched paperless operation and ticketless travel which means passengers receive an email containing their travel details and qualification reference instead of get a paper ticket when they book online. This lower the cost of issuing, distributing, processing and reconciling millions of tick ets each year. At the akin time, Easy jet simplified its work practice by delivery the concept of paperless operation and a well designed information system offers management and administrative job carried out through its IT systems of company. The no-frill service on board is another reason for Easy Jet to keep cost low, because everybody always complain roughly nutrition on board so why bother to provide food if people dont want it? Cutting off free catering on-board abate cost and unnecessary bureaucracy and management. It is also an important differentiator between easyJet and other airlines and a potent reflection of our low-cost approach. Passengers can purchase food on-board if they need it . ironically, Easy jet have won awards for our catering service. The new concept of a simple service model also reflects a more general need about eliminating other unnecessary, costly services. pre-assigned seats, interline connections with other airlines and cargo/freight carriage a re the characteristics of traditional airline result in high complex to manage cost.Moreover, easyJet use airports effectively by flying to main destination airports throughout Europe with high frequency and obtain efficiencies through rapid turnaround times. By cutting off turnarounds time to 30 minutes and below, easyJet can gain extra turnaround rates on the high-frequency routes, thus, maximizing utilization rates of its aircraft. Easy Jet made an agreement with airports about progressive landing charges.the operationeasyJet currently has operating various bases throughout the UK and mainland Europe. It is a really European operation and was one of the few airlines to take advantage of the reforms protracted by the single European aviation market.Manage costFuel cost is one of the biggest and volatile single cost for Easy Jet therefore fuel efficiency is very important to Easy Jet. In 2009, Easy jet salvage 1.2%of fuel they burn through the value of fuel efficiency and new fl ight planning system. Easy Jet have aimed a 3% improvement in fuel burn, which will deliver 20million by 2012. It is crucial for Easy Jet to manage cost effectively so that it can continue to offer competitive fares profitably. Easy jet plans to make at least 190million of cost decline by the end of 2012, which will allow Easy Jet to starting time lumpary pressures and produce 1 per seat benefit to the bottom line. The crew efficiency will be improved by 10% through route and crew optimal tools and a new roster system.Marco-economicTransport economics in general, especially air transport has been viewed as the laboratory of economic activity. well-fixed transport derived by booming economy, as an increasing economic activity, expanding industrial production and booming trade relation will inevitably lead to an ever-greater need for transport. A decline of the same parameters will reflect on a decreasing demand for transport. Within the transport industry, air transport seems to be more sensitive to such economic environs. In the face of recent financial crisis that affected world economic growth and international trade, airline industry are affected by this crisis.The EUs air transport system has been considered as a very important factor of the Unions economy. In the meanwhile, it is quite sensitive to economic environment and economic development in other industry. In 2008, the worldwide financial downturn had increasingly resulted in a global economic crisis. At the same time, the impacts of this crisis for air transport sector reflected on obvious decline of air travel demand because of less transported passengers and goods, reduction of supply through reduction of frequency, and lower company profits.Figure3 gross domestic product Yearly Growth from 1990-2008Inflation and Oil Price ImpactThe inflation rate in Europe was 0.90% in February of 2010. Inflation rate reflected on a general rise in prices measured against a standard level of purchasing powe r. The effective measures of Inflation are the CPI which measures consumer prices, and the GDP that measures inflation in the whole of the domestic economy. Oil prices are pushing up inflation across Europe. And oil price really matters to the health of global economy. The global economic downturn in 2000-2001 resulted from higher oil price since 1999, and global GDP growth have reduced. heightser oil price are contributing to high level of cost and unemployment and accelerating budget-deficit problem. The impact of high oil price on oil-importing countries varies mainly depending on the degree to which they are net importers and the oil intensity of their economies.. European countries are highly dependent on oil imports, which would suffer most in the short term, their GDP went down by 0.5% and inflation increasing by 0.5% in 2005. The United States suffered with GDP declining by 0.3%,mainly because its domestic production meets a bigger part of share of its oil needs. Japans GDP decreased 0.4%, with its low oil intensity compensating for its almost high dependence on imported oil.The problem of fuel rates/ cost is one of many factors all airline companies faced with. The price of a barrel of oil has been a huge impact on airliner and global airline industry. According to the statistics, the cost of fuel has been made up by 31% of the total cost of business of airline companies. The aviation industry is always sensitive to the change of fuel price. In the economic recession, the number of the passenger would scare away if airline company rise the ticket price, despite of the situation of fuel price surge. Therefore, the only ways for airline company to minify the loss because of the higher oil price are strengthening management, cutting cost and efficiency improving, instead of simply rear the price.Another financial risk exposure in the airline industry is interest rate. Interest rate risk is important to airline companies in foothold of the cost of debt finance. Higher financial leverage ratios are dominant in the aviation industry because of its capital intensive nature and high cost of equity. High earnings volatility made cost of equity increase. Equity can be less attractive due to lower price earnings ratios put in the airline industry. In the meanwhile, cost of debit is closely related to the interest rate changes. Therefore, the impact of interest rates on general business could be large consequential effect. Moreover, high interest rates result in higher cost of distress, this is especially for the airline industry.Legislation Impact cardinal of the most difficult balancing acts that airline companies faced is the challenge of balanceing global warming and remaining competitive position in marketplace. The airline industry is trustworthy for 2% of the worlds man-made carbon emissions and 6% of the Uks. It has already achieved a great deal in keeping emissions down,and it is continuing to take its responsibilities serious ly through industry-wide initiatives, in-depth research, roadmaps, not to mention new airframe and engine technology.In 2005,the temper impacts of aviation have finally landed on european political agenda.because the air travel is the worst climate choice of all transport modes, per passenger kilometer of aircraft emits tree times more than cars. Per tonne kilometer of freight, aircroft measured about an modulate of magnitude worsened than lorries. the UK Climate Change Act, passed last November called into question how quickly the industry could deploy into new aircraft and fleets the technological advancements it was claiming were going to help it deliver a percentage reduction in CO2 emissions. Airline companies must act quickly to lower its own CO2 emissins to meet goverment regulation,many people argued that the climate change policies will destory the development of aviation industry. However, the study shows that climate change legislation could be designed in a sustainable way.Survival of the Easy Jets cheap ModelLow-cost airline model has proven to be successful, and has been copied by the many airline company worldwide. Low-cost airline model is based on strict union to several major principles point to point flight, maximization of flying hours, short-haul, use of secondary airports, no-frill, and no delay, which result in low cost, low fares and high demand and capacity utilization. ( Macario et.al.2007) Although the air transport market is heavily impacted by the economic crisis, in turn, economic recession provides a potential opportunity to low-cost airline company. Easy Jet announced a profit increase in 2009. Low cost airline companies are increasing their market share compared to traditional airline.Potential strategies for Easy JetFirstly, Easy Jet should build stronger air transport network. Although Easy Jet has a leading presence on Europes top 100 routes, it still needs to strengthen its positions in the key market and focus on the r outes customers find the most attractive, at convenient times. Easy Jet needs to continually manage schedule quality and fine-tune its network. Which means it will offer customers the opportunity to arrive when they want and when they want. It will allow Easy Jet get increasing market share of flight and have higher load factors than its competitors. Increasing frequency and stability on major routes with launching new the route mix offer more choice to its customers based on market research. For instance, Easy Jet launched flight with daily think flight from several cities in UK to many European cities. As the demand declines through the summer months, it should manage its schedule and move assets to leisure routes in order to maximize its capacities. In addition, unnecessary cost created by overnight stops could be avoided by base management, in order to improve efficiency and maximize revenue.Secondly, it is important to listen to customer and understand their need and then desi gn schedule and service to match. the relative effective way to get close to its customers is to cod all customer data, which provides a fast and intelligent view on trends in customers travelling habits. With these customer databases, it allows marketing department tailor marketing emails correspond to individual customer purchasing patterns and preferences.Moreover, build increasing customer experience to appeal business travelers. Departure time is vital for customer and ensuring customers arrive at their destination on time is a key to delivery of a winning customer proposition. In a recession economic environment, Easy Jet has potential opportunity to increase share of the business travel market due to many corporate tend to low cost air travel company to cut business cost.http//hubpages.com/hub/rise-in-fuel-prices-airline-industryHow a rise in fuel prices affect the airline industry

X-ray Crystallography Technique Analysis

X-ray Crystallography Technique Analysis1 Limitations of x-ray crystallographyFrom the foremost crystalline anatomical structure determination of table coarseness in 1914 whose structure elucidation proved the existence of ionic manifolds (6), single crystal x-ray diffraction (SC-XRD) has been widening our view of the hidden world of molecular(a) structures. Today, SC-XRD continues to be the only structural analysis method that offers direct structural information at the atomic level. As such, this technique has been vital for reliably solving some(prenominal) structures of small molecules such as neurotransmitters, antibiotics and industrial catalysts.SC-XRD utilises the ability of crystalline atoms to scatter or diffract a beam of incident x-ray into a serial publication of amplified and spatially constrained beams (3). The angles and intensities of these beams piece of tail be measured and computationally processed by a crystallographer to make grow a 3-dimensional image of the density of electrons in the crystal. away from the expertise required to process the reflection data produced, the fundamental requirement of crystals for this technique acts as major limitation, since single molecules scatter the incident x-ray to produce a weak, continuous beam that provides little useful information for analysis. While technological advances in recent decades including highly intense x-ray beams produced by synchrotrons and the teaching of more powerful algorithms for molecular structure imaging have allowed the size of the crystal required to be increasingly smaller, the need for a crystal has keep mum not been eliminated. This poses a great issue as many stub compounds atomic number 18 very difficult to crystallise, thus requiring experienced specialists while others will barely not crystallise at all. In 2013, a new protocol, later coined the crystalline sponge method (CSM), was reported that attempted to bypasses this intrinsic limitation of the ta rget molecule needing to be crystalline (1).2 The journey of the crystalline sponge methodExpectationsFujita and his team described the new method that promised to speed up SC-XRD drastically by eliminating the crystallization timber of the target molecule. This was done using porous metal organic frameworks (MOFs) that act as crystalline sponges. Due to the high molecular recognition capability of their pores, these sponges can absorb target molecules from the sample tooth root into their pores. In their study, Fujita and his team used dickens MOFs synthesised from tris(4-pyridyl)-1,3,5-triazine (TTP, 1) and the appropriate metal salt as their crystalline sponges (Co(NCS)2)3(TTP)4x( effect)n (2) and (ZnI2)3(TTP)2x(solvent)n (3). In both abstrusees, the void spaces showed strong natural covering properties for incoming customer molecules making them ideal crystalline sponges. The as-synthesized complexes2 and 3 contained solvents in the void. By soaking the crystals of 2 and 3 in a guest solution, guest molecules loathly penetrate these wet cavities by guest exchange, and are concentrated at the molecular-recognition pockets surrounded by TTP. A characteristic of the strong host-guest interaction in the crystals of 2 and 3 lies in panel ligand1, which attracts various guests onto its electron-deficient -plane. The slow guest exchange allows for the process to remain under thermodynamic control, rendering the geometry of the included guests to be regularly ordered and well equilibrated, thus making it workable to analyse the accommodated guests by crystallography since the molecular structure of the absorbed guest will be displayed, along with the host framework.Since theoretically, only one crystal is needed to suffice the experiment, Fujitas team found that even trace sample amounts of the microgram-nanogram scale can be analysed in this protocol. When the team used only 80ng of guaiazulene guest sample with a crystal of 3 (80-80-80m3), they were sur prised to see the guestwas still clearly observed. Considering that the experiment was carried forth using a laboratory X-ray machine, it seemed promising to accomplish crystallography with synchrotron X-ray experiments even on a mass of In order to assess the scope of the method, the team carried out blind crystallographic analysis of six appropriate samples (Fig) with only 5g of each sample. In conjunction with mass spectroscopic data, all six structures were decent assigned, with three of the structures solved solely from the crystallographic data. Additionally, the protocol was successfully used to determine the out-and-out(a) stereochemistry of santonin 4, an anthelminthic drug bearing four chiral centres. Unlike common absolute structure determinations, this was achieved without the chemical substance introduction of heavy atoms on the guest skeleton since the host framework contains heavy atoms (Zn and I) that show enhanced anomalous scattering effects. (ExpandThe close t o impressive result of the teams protocol however was determining the absolute structure of miyakosyneA 5, a scarce natural marine product recently obscure from a marine sponge Petrosia sp. The structure contains three chiral centres on its main alkyl chain, two of which, C3 and C26, had been previously determined to be 3R and 26R respectively. However, since the difference between the two long alkyl groups on C14 is only one methylene unit, determining the absolute configuration at C14 was ineffective by conventional spectroscopic and chemical methods. As the amount of miyakosyneA was very limited, provision a single crystal for X-ray crystallography would propose a huge challenge. The team were able throw their method to the full characterization of miyakosyneA to determine the absolute configuration at C14 and reported success. For its appraisers, it was this result that made this new protocol transformational (4) and understandably it lead to a lot of excitement in the fiel d.1.3 The FallThe sign lustre of the protocol was dulled as Fujita and his team published a correction on the sign report later that year (1b). Previously unnoticed ambiguities in the crystallographic data, alongside further investigation of by the team found the initial appellative of stereochemistry at C14 of 5 to have been incorrect. Synthetic studies by the team determined the methyls stereochemistry was opposite to the original assignment reported. Poor data quality was concluded to be the cause of this errors.Additionally, more problems were met as other research groups tried to use the technique in their own labs. Although success with the technique was achieved for simple molecules, in the first few months, other groups found little success with any interesting structures, particularly large molecules or molecules containing alkaline chemical groups (8b). Fujitas team were able to economic aid other industrial and academic groups to master the technique in one to two wee ks. Additionally, more of the issues in reproducibility were improved by the release of a more detailed report of the method (1c) that described the sponge synthesis, pore-solvent exchange and selection requirements for high quality single crystals for crystallography. However, this did not address the issue of miserable data quality that led to the misassignment of 5. Since poor data quality can be attributed to all steps of the CSM, including cystal synthesis, solvent exchange, guest-soaking, data collection and crystallographic refinement of the host-guest complex molecules in order to move the CSM from the fascinating idea phase into becoming the transformational and reliable new technology it was envisioned to be, much work was required to optimise all these steps.3. (ZnI2)3(TTP)2x(solvent)n The most successful sponge to date3.1 Andvantages of (ZnI2)3(1)2x(solvent)nIn their initial paper, Fujita and his team reported using sponges 2 and 3. With further investigation, in the c ase of complex 2, it was observed that guest molecules absorbed in the sponge were prone to static disorder as they tend to lay on the concord elements of the cubic lattice (Fm3m). Additionally, complex 2 was shown to undergo unfavourable transformations when removed from solution (8c). This destabilising transformation, accompanied by a colour change from orange to green, resulted in a semiamorphous solid with a significantly altered coordination environment at the metal centre. As such, the less symmetric (C2/c) complex 3 has been employed as the primary host complex for the crystalline sponge. The versatility of 3 as a crystal sponge stems from several advantages in host-guest complexation in the pores. Firstly, the size of the pores is ideal for cooperative organic molecules of common sizes, while the hydrophobic nature of the pore cavities provides favourable binding of common organic molecules. Also, ligand 1 in the complex offers flat and electron-deficient binding site, ap propriate for stacking with resonant compounds and for CH- interactions even with aliphatic compounds (9). Since the I atoms in the ZnI2 are good hydrogen-bond acceptors and the pyridyl protons of the ligand 1 are good hydrogen-bond donors, they provide efficient binding sites with hydrogen-bonding. Finally, the framework of sponge 3 is reatively flexible with the size of the guest not strictly limited to the pore size of the complex. Molecules larger than the portal are oftentimes accommodated by expanding the pore size. (1.3)3.2.1 Synthesis of (ZnI2)3(1)2x(solvent)n and solvent exchange by Fujita method and updated Clardy methodIn their investigations, Fujita and co-workers prepared 3 by layering a solution of zinc iodide in methanol onto a denser solution of TTP (1) in nitrobenzene. The solution is allowed to stand for 7 days, over which crystals form at the boundary of the two solvents as they diffuse before dropping to the bottom of the test tube and being isolated by filtra tion. The as-synthesised crystals contain nitrobenzene molecules in the void spaces. However, since nitrobenzene has a high relationship to the pores, target guests are poorly absorbed into the as-synthesised crystal. As such, a solvent exchange step that replaces nitrobenzene with an inert, noninteractive solvent is required prior to soaking the crystal in the target guest solution.Cyclohexane can be adopted as the inert solvent, while pentane withal proves useful for guest soaking at temperatures below 0oC. The solvent exchange step is carried out by soaking the crystal in the inert solvent for 7 days at 50oC. The success of the process can be monitered throughout by observing the disappearance of the signal at 1346 cm-1 in an Infrared (IR) spectrum, which can be assigned to nitrobenzene. Completion of the process is sustain by SC-XRD by the presence of ordered cyclohexane molecules in the pores. The sponge whitethorn now be used for guest absorption. This solvent exchange proc ess may complicate the refinement of the structure, since some nitrobenzene may reamin within the sponge structure after exchange (Vinogradova et al., 2014). This becomes an issue if the target guest molecule contains cyclohexyl or aromatic rings, as it may be difficult to distinguish the guest from residual solvent, especially if the site occupancy is low or the data quality is poor. go with with heavy use of crystallographic restraints, this increases the risk of misassignment of the desired guest molecule by using residual solvent electron density. Additionally, if the residual solvent and the guest interact similarly with the host, the likelihood of occupational disorder increases and making structure refinement much more challenging.Clardy and co-workers later reported a simpler and less timely preparation method for the synthesis of sponge 3 using similar conditions to those reported by Fujita and his team. (5sync) Instead of conducting the layer diffusion step with TTP in ni trobenzene, TTP is dissolved in chloroform. As such, the as-synthesised crystals of sponge 3 contain chloroform in the pores. Since chloroform has a much lower affinity for the solvent pores than nitrobenzene, the solvent exchange step can be omitted and the as-synthesised crystals used immediately. As well as saving 7 days of preparation by omitting the solvent exchange step, this method is also milder as it does not require the crystal to be heated for long periods of time. This reduces the chances of introducing imperfections in the crystal.This omission also minimises the number of solvents that the crystal is exposed to, reducing issues in structure refinement. Although some CHCl3 might remain within the sponge after guest inclusion, due to its longer C-Cl bond length (1.7) and larger Cl electron density, CHCl3 can still be observed. This greater electron density for CHCl3 exerts a larger influence on the structure factors relative to incorporated guest compared to nitrobenzene , however the benefits of CHCl3 usage override this issue.In addition to the desired crystals, this preparation method has been found to simultaneously form other crystalline structures. Firstly, a crystalline compound with the formula (ZnI2)3(TPT)2CHCl3n (2), having a much smaller pore size has been viewed. Fortunately, this crystalline structure can be easily distinguished from the desired structure from its syllable structure (Fig). A second undesired crystal has more recently been observed with consistently distinct unit parameter, but having indistinguishable morphology to the desired structure from its morphology (Fig). Both these crystals are believed to form due to slight changes in humidity and temperature as well as variations in mixing in the initial stages of the layering process. desired crystal. Both these crystals are believed to form due to slight changes in humidity and temperature as well as variations in mixing in the initial stages of the layering process.

Lung Cancer Screening With CTKaryn TerryPima Medical InstituteFebruary 12, 2014Lung Cancer Screening With CTLung crabmeat is the leading cause of death from cancer within the United States with tobacco smoking being the biggest risk factor. In 2012, more than 220,000 people were diagnosed with lung cancer and approximately 150,000 died from the disease. Lung cancer rates in the United States climbed dramatically throughout much of the 20th century, as smoking became more popular, and peaked in the 1980s before declining in the 1990s (Furlow, 2014, p. 298). Screening of high risk people for lung cancer has been extending patients lives with early detection with the use of computed tomography (CT). Likewise, lung cancer affects people who put one across never smoked due to the presence of radon and household pollutants. Radon has contributed to 10% of all lung cancer deaths and is considered second to smoking. There is no way to previse who will get cancer, but inherited genetic risk factors make some people more vulnerable to carcinogenic exposures than others. Lung cancer starts whenever there is an anarchical growth of abnormal tissue cells that affect the normal function within the lungs. As these abnormal cells grow they form tumors which can block the oxygen veer within the body. (Lungcancer.org, 2014). Original screening for lung cancer was done with the use of standard radiographs, but recently computed tomography (CT) is being used because it offers greater sensitivity in detecting pulmonary nodules.
