Dq - Essay Exampler product differentiation) where the selling strategy is to distinguish their product from competing products or services on the basis of workmanship and design.In an oligopoly setting there a few sellers that sell a differentiated or standardized product where the decision of competitors affects the change of a firm. Therefore, firms consider the strategies of competitors to determine its output and price (McConnell 2005 p.177).A start up company female genitals expect profit when the business is able to grapple the expenses including the start up costs. The sale of products should earn enough revenue to meet ongoing expenses associated with the operation of the business. A start up business entrepreneur must(prenominal) realize that a product sales amounting to $10,000 will not cover a monthly overhead expenses of $10,000 because the sales returns has a gross profit of totally around $4000. A business reaches break even point when the sales revenue is equal t o all business costs. The break even point can be calculated by identifying the fixed costs and variable costs. Fixed costs are expenses which do not change with changes in the volume of sales. For example, administrative salaries and rent remains the same and are expenses that must be met regularly irrespective of the volume of sales. These are usually known as overhead costs. changeable costs fluctuate with changes in the volume of sales. Variable expenses like shipping, purchasing inventory and manufacturing costs of a product has to be met for a start up company to make profit.Market structure and the distribution of income raise concerns about the formation of monopoly power where increased concentration of control moves into the hands of few noncompetitive firms. Monopoly leads to decreased competition among firms and inefficient distribution of resources in the economy. Monopoly has an impact on the distribution of income. Research indicates that monopoly power reduces the income share of workers when compared to capitalists,

vitiate bird of passage EssayThus the force of gravity on Mars is to the highest degree one-third of that on Earth. Mars is probably the orbiter we know the most about since it is so close to Earth, though what we know now is not even close to everything about the planet. Over the past several decades, humans have been interested about life on mars. In 1877, Giovanni Schiap arelli, an Italian astronomer, was the first person to draw a map of Mars. His map showed a system of streaks or channels, which he called nookyali. In 1910, the U. S. astronomer Percival Lowell made observations of Mars and wrote a book.In his book, Lowell described Mars as a dying planet where the civilizations built an extensive network of canals to distribute water from the polar regions to the center of the planet. Mars was discovered by scientists in the 1600s. Researchers descried a pale pink object that was only visible in the early morning just before dawn. The object moved closer to the stars, got brighter over the succeeding(a) year and rose earlier and earlier. Then it reversed direction. Mars was the third most brightest object in the night sky, it had an intense red color and could fascinate all night long.After moving the opposite direction for about 70 days, it reversed direction again, and gradually got dimmer. It was only visible in the even sky and set earlier and earlier. After another year it again was a pale pink object, this time only visible just afterwards sunset. Shortly after that, it could not be visible at all. It remained unseen for about one hundred days when the cycle began again. Each cycle took a little over two years. Scientists believed that water may have existed on the planet Mars. The total journey time from Earth to Mars takes between 150-300 days epending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target. We would need food, waste disposal, oxygen, and the matter of getting back to earth. Another terra firma we wouldnt send humans to mars dont know how our body would react to mars atmosphere. Mars doesnt have a magnetic field, such as earth, our planet blocks it out. If a human went to mars for a period of time there is a 40% chance they would come back with cancer. So at this time spiders are our best option.The first rover ever sent mars was in 1962 called Mariner 3. The rover never landed on mars it was a flyby which way of life it only took pictures of the planet while in obit. In 1965 Mariner 4 took more pictures. In 1969, flybys ended and NASA came up with spacecrafts. Mariner 9 was the first rover to take pictures of the entire surface of Mars when it landed in 1972. In the mid 70s, they launched Viking 1 and 2, they were the first to discover ultraviolet radiation with alter soil and oxidizing nature preventing organisms from forming. The cost, to build a rover is about 2. 7 billion dollars, for us to send over humans the cost is twice as much. Sojourner, which launched in 1996 and landed in 1997, was part of the Mars Pathfinder Mission. The itty-bitty rover weighed in at 23 pounds. It was 26 inches long, 19 inches wide, and 12 inches tall. In 83 Martian days of operation, Sojourner never ventured more than 40 feet away from its lander, and its odometer for the whole trip read only about 330 feet. The rover snapped 550 photographs and performed tests on a rock nominated Yogi. In 2001 NASA discovered ice when the spacecraft Odyssey orbited Mars and took pictures.What facial expression and Opportunity found was a credit to the technology that allowed them to explore Mars. deep down a couple months of landing, the Opportunity uncovered evidence of saltwater, which leaves open the possibility that life (and fossil indications) might at one time have existed on the planet. Spirit stumbled across rocks that pointed to an earlier, unrulier Mars that was marked by impacts, explosive volcanism and subsurfa ce water source NASA Mars. Water is key because almost everywhere we find water on Earth we find life, NASAs Web site. However, we are still unsure life existed on Mars.The rover Curiosity, finally landed on mars August 6, 2012, it was launched November 26, 2011. in the first place NASA could be launched Curiosity, the rover it had to go through series of test, drop tests, pull test, drive test, load test, stress tests, and shorting tests. So scientists had to realize that Earth and Mars swan around the sun at different rates meaning it takes Mars 686 earths days and the Earth 365 days. They did to figure out when Mars was closest to Earth. Curiosity was launched from chimneypiece Canaveral. Stage one, it reaches space and the tip of the cone opens and fall off.During the second stage, a centuar engine starts placing the vehicle into obit. When everything is alined the second engine starts to bring it to mars. Once Curiosity is on Mars it will do tasks such as collecting rock, so il sampling and placing them on instruments in order to be collapsed. What goes into the rover (Siceloff, Steven. Mars Rover Well-Equipped for Studies. NASAs John F. Kennedy Space Center. Nov. 22, 2011. (Dec. 9, 2011) http//www. nasa. gov/ guardianship_pages/msl/launch/mslprelaunchfeature. html) A miniaturized gas chromatograph and mass mass spectrometer will separate and analyze chemical compounds in samples.A tunable laser spectrometer will look for organic (carbon-containing) compounds and determine the ratio of key isotopes both vital to unlocking Marss atmospheric and aquatic past. CheMin, an roentgenogram diffraction and fluorescence instrument, will measure the bulk report card of samples and detect their constituent minerals. Located on the rover arm, the Mars Hand Lens Imager will photograph rocks, soil and, if present, ice in extreme close-up. This uber-camera can spot details thinner than a human hair or focus on objects more than an arms length away.The Alpha Part icle X-ray Spectrometer for Mars Science Laboratory, also located on the arm, will figure out the relative amounts of various elements present in Martian rocks and soils. Curiositys neck, or mast, is also decked out in instrumentation The Mars Science Laboratory Mast Camera (MSLMC), attached at human-eye height, will help the rover navigate and prove its skirts in high-resolution stereo and color stills or high-definition video. The MSLMC can view materials collected or treated by the arm. Stereo hazard-avoidance cameras located just down the mast will aid the rovers navigation.Another mast-mounted instrument, ChemCam, will vaporize thin layers of material up to 30 feet (9 meters) away using laser pulses, then analyze them with its spectrometer. Its telescope can capture images of the beams target area. The Radiation Assessment Detector will monitor surface radiation levels. The Rover Environmental Monitoring lieu will take readings of atmospheric pressure, temperature, humidity and wind, as well as levels of ultraviolet radiation. The Dynamic Albedo of Neutrons instrument can detect hydrogen a potential indicator of ice or water trapped in minerals up to 3 feet (1 meter) beneath the surface.Earthlings have long been fascinated by the planet Mars. Well before modern science fiction speculated about advanced civilizations upon Mars, the red planet was regarded as a malevolent agent of war, pestilence, and apocalyptic possibility inhabited with little green men. For untold millennia prior to scientific astronomy and well before there were any records which could properly be called historical, human beings recounted myths surrounding their favorite heroes and gods about Mars.It wasnt until the 17th century when Mars was first discovered by scientists that we began to understand the red planet. The first rover sent to Mars was in 1962. The first successful mission was the 1964 trip by the Mariner 4, a United States craft that returned 21 images of the plane t. In 1969 the flybys ended and In 1972 pictures were taken of the planets surface by the rover Mariner 9. Viking 1 and 2, which launched in the mid-70s, both had landers that descended to the surface of Mars.In 2003, the Mars Exploration Rover mission team launched Spirit and Opportunity, one of which was still traversing the planet as 2011 ended. Which leads us to Curiosity and 2012. Curiosity, previously known as the Mars Science Laboratory weighs 2000 pounds and has a planned mission duration of 23 Earth months, which it could exceed by quite some time, based on NASAs experience with the Spirit and Opportunity rovers. True to its old name (Mars Science Laboratory), Curiosity is packed with instruments as mentioned above. Who knows what our curiosity will lead to. Hopefully, life.

Is Ritalin Over Prescribed Essay Example for Free

Is Ritalin Over Prescribed EssayAfter reading the selected critical issue, use the following questions to con sider the issue.1. What are at least two facts presented by each side of the critical issue? Pro on that point were more than a dozen reports of cardiac arrest or heart failure between 1985 and 1997 due to Ritalin use. In one study, Ritalin use reduced the expected monthly encumbrance gain by 25%. Con Stimulants take for proven to be effective in improving behavior, school work and social adjustment from 50% to 95%. For 30% to 45% of children with minimal brain dysfunction, the use of stimulants will improve their behavior but not be normalized. 2. What are at least two opinions presented by each side of the critical issue? Pro Children taking stimulants frequently become very depressed or suicidal. Stimulants can cause a conversion of mental abnormalities. Con It is a myth that the use of stimulants stunts a childs growth. There is no investigate to prove tha t children taking stimulants are at more of risk for abusing other drugs during their teenage years.3. What are most of the strengths associated with the Pro side of the issue? What are any(prenominal) of the weaknesses? The Pro side has a sizable amount of scientific data and several studies to help support their financial statement for the negative side make of stimulant use. The Pro side is very convincing using the many data tables to depict the harm that stimulants can cause to children. They use several different sources to support their argument. The Pro side does not explore the other side of the argument whatsoever. man they have a substantive amount of data, it is not compared to the number of children who experienced no negative side effects while using stimulants. This would have caused their percentages and numbers to be much smaller.4. What are some of the strengths associated with the Con side of the issue? What are some of the weaknesses? The Con side effe ctively argues that Ritalin and other stimulants are very useful in treating and normalizing children with ADHD. The Con side also explores the other side of the argument by admitting that some children do experience negative side effects. An entire section of the argument is dedicated to discussing the side effects of stimulants. The Con side of the argument is supported by a great deal of research and data. Weaknesses of the Con side include not using cited sources to support his argument other than his own.5. How credible were the authors of each argument? Explain your answer. Physician, Peter R. Breggin, was convincing in his argument that stimulants are harmful to children and is overused. He used several sources and data from other research teams to support his argument. Psychologist and ADHD researcher, Russell A. Barkley is very convincing in his argument that Ritalin and other stimulants are important parts of intervention for children with ADHD. It is apparent that he acc omplished blanket(a) research to write his book and present this argument.6. Based on the statements presented in this critical issue, which author do you agree with? Why? This is a difficult question to answer. While I know there are many side effects associated with the use of stimulants, I have witnessed the more positive aspects of using these drugs. Barkleys extensive research and presentation of his findings is very convincing. That partnered with real life experience using these stimulants, causes me to agree with Barkley.7. Which side of this critical issue does contemporary research support? enrapture provide specific examples in your response. The Pro side is more supported in contemporary research. Pro There are several articles and journals that I have found that support the Pro side of this argument. Ritalin is thought of as the quick fix for ADHD. Because it is an amphetamine, Ritalin has a high rate of abuse and concerns some parents, teachers and physicians. Some s ay that they feel pressured to give or recommend medication to children before they can perform a thorough evaluation of a student. There is also a concern that Ritalin is being prescribed to children too young to solve normal behavioral problems (Huber, 2002).

Effects of Exercise Essay Example for Free

Effects of Exercise EssayIn this assignment I will be reviewing the different effects of mold on the body system including the acute and long name using the pre-exercise, exercise and post-exercise physiological data which I serene based on interval and continuous training method. I will to a fault be including the advantages and disadvantages of these, in like manner the participants strengths and areas where they can improve on.-Effect of exercise on the musculoskeletal systemAs Andre began to exercise, this had an effect on hes bones this is because he was putting more nidus on them than usual which resulted in them acquiring thicker. in any case exercise had an effect on hes joints because the joints now became more flexible and he wasnt get anymore pains during or after physical exercise which was an progress for him. A short term effect that Andre was capable of nonicing is that his muscles was getting more flexible as he continued to exercise, this prevented him from getting any injuries, also it helped hes performance.Another effect is the range of movement this is because as he continued to exercise his body got used to the stress it was being put under which led to the synovial fluid decorous less viscous. Addition solelyy for the long term effects, Andres muscles was capable of tolerating lactic sexually transmitted disease this effect was noticed when Andre stopped complaining about the stitches he got in his legs while exercising. He stopped complaining because his muscles were using fat as a source of fuel when there wasnt any oxygen available for the muscles. Also Andres muscles werent getting bigger moreover it was increasing in its strength this is because of the training methods used for his six week training programme.-Effect of exercise on the cardiovascular systemWhen Andre was exercising, a lot of hes zippo was getting used up quickly. This energy is gained from the oxidising glucose this factor that not only oxygen mus t be delivered by the blood but it has to deliver glucose too. This resulted in Andres heart having to work twice as hard in order to pump more blood around the body. As Andre continued to exercise his heart muscle and cardiovascular system became more efficient which resulted in him improving hes endurance because he was capable of running prolonged as more blood was circulating the body quicker than before. Additionally a short term effect which affected Andre while he was exercising is that he was gasping for more oxygen which led to him inhaling more oxygen than usually which caused carbon dioxide to be exhaled rapidly.Plus another short term effect that was noticeable was his heart govern which increased rapidly this is because he was exercising harder than he normally does, also he was doing these exercises for a long period of time. Whereas the long term effect which was noticeable was the way Andres heart rate was decreasing quickly this was because his heart was gettin g used to the regular exercise, also his heart was getting healthier and fitter. Another effect is that Andre was capable of increasing his aerobic capacity as his body adapted to the regular exercise which resulted in his heart and lungs becoming more efficient.-Effect of exercise on the respiratory systemAndres respiratory system is affected by exercise because when he was actually doing the different exercises, his muscles involve more oxygen and for carbon dioxide to be produced so that hes heart can work quicker and he would be capable of lively faster and deeper to let the carbon dioxide exit quicker and the oxygen enter and be pumped around quicker. A short term effect that was noticeable is when Andres breathing rate increased this is because of the chemoreceptors which are found the blood vessels and sensed a sudden rise of the train of carbon dioxide in the blood.This also caused the depth of Andres breath increased. Another short effect is the increase in tidal volume this is because Andre is breathing more as more behavior passes through the lungs. In addition to that, the long term effect has also had an effect on Andre for example he has increased the vital capacity which means that the lungs are capable of supplying more oxygen to the muscles with vital nutrients and this results in the lungs to expand. Also hes oxygen diffusion rate has increased callable to the more oxygen which is absorbed by the alveoli and then circulated around the body.Before the training programme Andres fitness level was not poorly but it wasnt at hes vanquish though and in order for him to improve on hes cardiovascular endurance, I created a six week training programme in which involved different exercises and training methods that he should use to improve on this skill. Also before he started this training programme, I canvassed Andre on some assays which areMultistage fitness test Stage 5.9This result shows that Andre is not at hes best fitness level because after this test was conducted he was struggling to breathe and he kept commenting that hes legs was in pain. 35 one thousand style 5.25 SecondsThis result shows that Andres is just below mediocre, and therefore he is unfit as he did not even reach the average stage of this test for someone at hes age. Illinois agility test 17.3 SecondsThis result shows that he bad with hes coordination as he only reached the average result because this was hes best result after trying this test 3 times.After the training programme Andre could clearly see that hes fitness level has improved because he could now run for a longer time as he worked hard to improve hes cardiovascular endurance. After Andres training programme, I conducted the same tests before he started the training programme and this are the results for themMultistage fitness test 35 metre sprint Illinois agility test Stage 6.5 4.82 Seconds 15.2 SecondsComparing both pre and post tests, I can clearly see that there is a change betwe en the level of fitness Andre is working at this shows me that hes good with training programmes as he was capable of following the 6 week training program which led to him not only improving hes on hes multistage fitness test but also hes 35 metre sprint and agility test.Advantages and disadvantages of the tests-Multistage fitness testThe Validity of the test is that there are published VO2 max score equivalents for each level reached the correlation to actual VO2 max scores is high. The Reliability of the test would play on how strict the test is directed for example the coach can be very strict by not allowing the jockstraps to make any mistakes, also it depend on how the athlete is motivated to do the test. Furthermore, the advantage of this test is that it can be performed in large groups of athlete. Also the test really tests the athletes compared to other tests of endurance capacity. These are advantages because it ensures that the athlete knows exactly how healthy and fit they are and they can use that to their advantage. However, the disadvantage of this test is that the athlete would be less motivated and wont practice for the test this therefore can have an influence on the athletes overall score. Also the test should be through indoors to exclude environmental conditions which could possibly have an effect on the score of the athletes.-35 metre sprintReliability is greatly improved if timing gates are used. Also weather conditions and running surface can affect the results, and these conditions should be recorded with the results. If possible, set up the track with a crosswind to minimise the effect of wind. Also the hardness of the test refers to how the test is actually measured this test provides means to monitor the effect of training on the athletes physical development. Furthermore, the main advantage for this test is that it measures the run and acceleration of an athlete in any particular sport.This is an advantage because if every ath lete done this test then they would know their own speed and for an athlete this would help them on how to improve more on their speed level. Additionally, there are several disadvantages for this tests for example the poor reaction time and starting techniques, also the timing errors. These are disadvantages because they all have a large impact on the result of the test., so therefore this test can be done as many times as possible but there wouldnt be a correct result as the athlete would be extremely exhausted.-Illinois agility testThe validity of the test refers to how the test is actually measured this test provides a means to monitor the effect of training on the athletes physical development. Also the reliability of the test would depend on how strict the test is conducted and the individuals level of motivation to perform the test. Furthermore, the advantages of this test is that its very painless to set up and conduct as not a lot of equipment are infallible, also it can be conducted anywhere e.g. sports hall, playground. Whereas, the disadvantage is that an assistant is required to administer the test.The strength of the tests is that we done them in pairs this allowed us to measure one another which was good as we got to see how our partners were performing and if they were excelling or not. Also these tests allowed us to know our actual fitness level and what we would need to do in order to increase our fitness level and the way we perform. Whereas, when conducting the tests, I think that areas for improvement is to have better heart rate monitors this is because the ones that we were using something didnt work which caused the work to be inaccurate as we have to guess the heart rate of the participants.Also the facilities could have been better this is because we had to use the cage, astroturf, and sports hall but 2 of these areas werent always free whenever we wanted to use them. Additionally, the weather was really shabby this had an effect o n the overall performance of the athlete as they could not concentrate due to the bad weather condition as we had to do all of the exercises outdoors including the tests. Plus the tests results would have been better if he had done them at Brunel University because they have the correct facilities and monitors that would give accurate results.Bibliography newss-Adams, M., Barker, R., Gledhill, A., Lydon, C., Mulligan, C., Phillippo, P. and Sutton, L.

Ryanair British Airways | Fare comparison

Ryan bank line British Airways F atomic number 18 comparisonIntroduction This document reports the findings of a review of the economics and wrinkle literature on empirically-estimated own- expenditure walkover of learn for crease proceedling for Ryan breed and British Airways. It refers to the data on page two of the assignment handout to both above stocklines to illustrate and explain the concepts of scathe elasticity of require and income elasticity of read. The purpose of this study is to report on all or most of the economics and origin literature dealing with empirically rough demand functions for air travel and to collect a range of f ar elasticity measures for air travel proffer in the data on the molybdenum page of the assignment topic and provide whatever judgment as to which elasticity determine would be more representative of the true values to be found in divers(prenominal) airline such as Ryan air and British airways, furthermore will evaluate the ach ievement of be savings of Ryan air through dictated cost and vari sufficient costs as well as writing a critical analysis the article on baa Airports Notice of release of interim undertaking1. Price Elasticity of Demand and Income elasticity of demand in the context of air travel demand (Ryan air British Airways)This paragraph identifies two distinct worths for air travel which argon price elasticity of demand and income elasticity of demand. Specifically, it is observed that studies of the demand for air travel demand should distinguish among prices for Low cost carrier (LCC) casing of Ryanair and Full Service Carrier (FSCs) example of British Airways in this case study business and waste travel long-haul and niggling-haul travel and international and European long-haul travel. fitly, to examine the sensitivity of the demand for air travel to its price, separate estimates of the price elasticity of demand atomic number 18 gathered for each of these two distinct markets.Pri ce Elasticity of Demand Price Elasticity of Demand is a numerical value which describes the degree of reactivity of demand to changes in prices. (Andrew, D. 1988 260)The demand for a particular(a) good or service depends on a variety of factors. Key influences include, the levels of consumer income, the price and quality of the service in question and especially services that are close substitutes (Sloman, 2005). In order to obtain useful estimates of the price sensitivity of demand for a product, we mustiness carefully control for all the factors affecting the demand. As a general rule, once separate influences on demand stay unchanged, a high price for a product leads in a clinical depressioner quantity demanded. However, the price responsiveness of demand varies from one good to some other and from one market to another (FitzRoy et al, 1998). Since the availability of alternative modes of transportation that are reasonably close substitutes for air transport diminishes wit h distance travelled, it is expect that the demand for air transport will be less elastic for longer leakages typical example of British airways with is a FSCs than for shorter flights typical example of Ryan air. Determine the demand and for the premium value the demand is petty(a)-spirited. government agency that for the different strategies the demand is price strategy, in al produEach price will lead to a different level of demand and therefore remove a different impact on a companys marketing objectives. The higher the prices are the disordereder the demand of the goods (Kotler 2002). British Airways has two types of customers Price sensitive customers (students, independent travelers, often metres travelers) who are looking for the cheapest prices and the best offers, and Low sensitive customers (business and executive customers) who are concerned more in the quality than the price.Considering the three different determine strategies of British Airways the demand curve will be as shown in the figure be mortified. The price demand considers being elastic which means that for the different pricing strategies the demand is noticeable changing. For the low cost price the demand is high and for the premium value the demand is low.2.3.3 Cost estimationBritish Airways estimating the cost of the products in sex act with the quality its one provide. The cost of the slate includes The price of the service The added value (extras) The aerodrome fees, and The travel agents extra feesHowever if someone book a slate from the internet has at www.britishairways.com has a discount of 10.2.3.4 Pricing methodConsidering the three different types of customer, the three segments, British Airways has redact a pricing method of perceived value. Perceived value is the value seed by companys value proposition and the customer must perceive this value. British Airways perceived value is made up by the companys brand mane and image, the customers image, the performance of the company and the quality of the product created by the company.2.4 Promotional pricingBritish Airways has settle some promotional prices on flights to some special occasion Christmas gift voucher. The promotional offer for the Christmas known as British Airways escape ticket offers a perfect present. Flying to 14 travel zones from 59 return on UK and Europe destinations and from 269 return on the rest of the world. Domestic and European fares from 49 return Low fares to 135 destinations across Europe. nightspot World business class offer When flying to club world business class you can upgrade to first class on a free one way ticket.2.5 Relation within the sectorThe disceptation has increased since the introduction of the low cost airlines as unproblematic jet and Raynair. Those airlines have achieved to sell chip tickets by eliminating all the unnecessary costs. They eliminated the intermediaries, the on board value and basically they eliminated completely the augmented p roduct. They have concentrated nevertheless on the basic product which is the flight ticket from the on destination to the other. They using a low cost low quality pricing strategy and set a market penetration objective in order to gain more market share. The have a method of value pricing of selling their tickets, the basic, in a greater value than their competitors.Other companies with uniform objectives as British Airways like Lufthansa and Virgin have followed the same pricing strategies and policy. They set different price rates in relation with value added and looking after how to gain a bigger piece of the market pie.3. ConclusionConsidering the increased competition in the flying indus try which is rising people expect that companies will reduce cost by providing less quality products. That is partly true considering what easy jet and Raynair has succeeded. However this is only one part of the true. Companies like British Airways fight the competition with different metho ds like introduction of low cost ticket where customer can still enjoy a good quality product in a low affordable price. Just considering an example where Ryanair (a low cost airline) flights to Milan from 49.99 return and British Airways from 628 return. The problem though with Ryanair is that you can find this cheap ticket if you book it about it well in advance. But if you try to book it on the same day before your journey the price has gone up at 179.99 return when British Airways price will be still remaining the same until a week before your journey. So does it really worth flying with the low cost airlines which offer just a ticket with no allocated seat, no food or drinks and from unfrequented airports when you have a company like British Airways with so much extra for virtually the same price? Thats a question that each of as has to answer on his own. Further, international travel tends to be widen over more time than domestic travel, so that the airfare is a smaller propo rtion of overall trip costs, which makes international travel less sensitive to changes in ticket prices. In addition, leisure travelers are more likely to postpone trips to specific locations in response to higher fares, or to shop around for those locations offering more affordable fares. Consequently, it is expected that the demand for air transport for leisure reasons will be more elastic than business travel who usually travel with FSCs. According to Anthony et al (2000) Ryan air prices guidance is systematically offering different prices to different customer segments in response to demand whereas (Kimes, 1989) suggests that the team in charge of yield management fate to identify how changes in price will affect their customers. Within the airline industries customer demand may be higher on week ends, during pass months, or at particular times of a day, (Belobaba, 1987). Managers must be able to forecast time- associate demand so that they can make effective pricing and all ocation decision to manage the shoulder periods around high demand period. However the corporate business traveller during the week becomes a leisure traveller when on holiday or at week-ends. Different occasion find the same consumer having different expectation and needs, (Buttle, 1986). Such a concept is termed elasticity of demand.According to the Data downloaded from Ryan air website giving on page two of the assignment topic the price of the flight on the day it been downloaded is far more higher than the price of the flight on other following days of the week day. However, when approaching the end of the week-end or school holiday, there is a huge demand and the increased demand drives the price up again as customer are returning from their vacation or family are going on holiday. next to the date and time of the scheduled service, the price rises, on the simple justification that consumers demand for a flight becomes more inelastic the nearer to the time of the service. The low cost airlines such as Ryan air follow the pricing strategy outlined above. Customers booking early with carriers such as Ryan air will usually come across lower prices if they are ready to commit themselves to a flight by booking early. This gives the airline the plus of important how full their flights are likely to be and a source of cash-flow in the weeks and months prior to the service being provided. People who book late often regard travel to their be after destination as a need and they are therefore likely to be prepared and able to pay a much higher price very close to departure. Airlines call this price discrimination yield management but despite the consider name, at the heart of this pricing strategy is the unprejudiced but important concept price elasticity of demand.Ryanair has a seat pricing policy that causes fares to rise as a flight fills up (Ryanair.com, 2010). sideline theory of supply and demand, if customer wants a seat so badly, they will pay more fo r it than otherwise.Income Elasticity of Demand It is defined as numerical values which describe the responsiveness of demand to a change in consumer incomes. (Sloman, 2005) Because of the recession, demand for low cost flights grew rapidly as family with higher income who were travelling with FSCs before would like low cost than traditional airlines and some current low cost customer with low income may prefer domestic flight or would just prefer not to travel by air. However, since elasticity is measuring proportionate change, elasticity values will change along almost all demand functions, including linear demand curves. Estimation of elasticity values is therefore most useful for predicting demand responses in the vicinity of the observed price changes. As a related issue, we recognize that in markets where price discrimination is possible comprehensive data will not allow for accurate predictions of demand responses in the germane(predicate) market segments. In air travel, FS Cs are essentially joint products consisting of differentiated service bundles that are identified by fare classes. However the yield management systems employed by FSCs also create a complex form of inter-temporal price discrimination, in which some fares (typically economy class) decline and some increase (typically full-fare business class) as the departure date draws closer. This implies that ideally, empirical studies of air travel demand should separate business and leisure travellers or at least be able to include some information on booking times in order to account for this price discrimination, and that price data should be calibrated for inter-temporal price discrimination for example, the use of full-fare economy class ticket prices as data will overestimate the absolute value of the price elasticity coefficient. Within the set of differentiated service bundles that comprise each (joint product) flight, the relative prices are important in explaining the relative ease of substitution between service classes. Given the spirit of inter-temporal price discrimination for flights, the relative price could also change significantly in the time period prior to a departure time. In particular changes in real income and the prices of substitutes or complements will affect demand. Alternative transportation modes (road and rail) are important varyings for short-haul flights, while income effects should be measured for both short and long-haul. Oum et al. (1992) provide valuable tools that occur when evaluating the demand models. Air travel demand can be affected by changes in the prices and service quality of other modes. For short-haul routes (markets) the relative price and service attributes of gondola and train would need to be included in any model particularly for short-haul markets such as low cost airline. Failure to include the price and service attributes of substitutes will bias the elasticity. For example, if airfares increase and auto costs a re also increasing, the airfare elasticity would be overestimated if auto costs were excluded.The entry of low cost carriers leads to lower fares for a subset of traffic and competitors will offer a supply of seats to match these fares. Lower number fares should lead to lower demand elasticity estimates, while increases in the number of competitors in the market will lead to higher demand elasticity estimates.2. How low cost carriers such as Ryan air able to achieve cost savings? Fixed Costs and Variable Costs. Ryan airs business model is heighten around its general low cost philosophy. That is Ryan air attempts to cut all non value adding activities as it strives to drive costs down to the total minimum. Below are typical examples how it drives its downwards which include selling directly to its customer over the internet or over the phone rather than via agents and middlemen, thus saving heraldic bearing cost and administrative cost. Ryan air is a ticketless as most of it custo mer buy over the internet, in return for a booking reference that is transfer at the checking counter at the airport for a boarding pass.The airline has no in flight meals which is a cost saving measure that cannot be much inconvenience to its customer since all Ryan air flights are short haul. Nevertheless has subcontracted catering services on its flights where customer can buy an in flight meal and drink should they wish which is another way of driving price. Cabin crew double up as cleaner and this helps Ryan air to promise a turnaround time at any airport of 30 min rather than 45-60 min that has FSCs been the norm. Another cost cutting device, is the typical example of the UK smaller airports such as London Luton, cheaper to fly to from than bigger airports such as Heathrow which it is use at least as its base as they are less congestion and facilitate turnaround times for aircraft to be a lot shorter.Fixed CostsFixed Costs are defined as the Total costs that do not vary with the amount of output produced (John, S. 200582)Ryan air as a LCC operate in the environment of high fixed cost, fixed capacity in the short term, a perishable product and seasonal demand. Virtually all of airlines costs can be considered fixed. The cost of the heavy(p) tied up in the plane, the fuel it take to fly the route, the crew it will take to staff the ground and flight operations insurance, rent, etc whole these cost are fixed once the company decides to fly a particular route and the variable costs associated with serving another passenger on the flight are figure lively peanuts.Ryan air generates sufficient revenue through ancillary services such as car rentals, accommodation, currency, travel insurance, transactions, refreshments, to cover variable costs and offset at least some fixed cost. Management believes that providing these services through the internet allows Ryan air to increase sales, while at the same time reducing costs on a per unit basis.Variable Costs Var iable Costs are defined as the total costs that do vary with the amount of output produced (Sloman, 2005 82)The relatively low variable costs associated with many capacity- constrained Ryan air allow for some pricing tractability and give operators the options of reducing pricing during low demand times. Ryan air always seeks for low variable costs. Below are factors that help Ryanair to maintain a low variable cost* One type of aircraft, management believes that its strategy of limiting its fleet primarily to three variants of a unmarried type of aircraft from a single manufacturer enables it to limit the costs associated with personnel training, maintenance and the purchase and storage of spare parts, as well as affording greater flexibility in the computer programing of crews and equipment.* Pricing is based strictly upon revenue maximization process that matches the aims and objectives of prices elasticity of demand* Internet booking which cut paper and administrative costs* No airport sales offices/ no cancellations* Charging a surplus for excessive baggage* Maximization of seat capacity per planeUse of less expensive airport as Ryan air been offered incentives is a controversial one Ryan air director of communications. Ryan air further endeavours to reduce its airport charges by opting, when practicable, for less expensive adit locations as well as outdoor boarding stairs rather than more expensive jet ways. Ryan air has entered into in agreements on competitive toll with third gear party contractors at certain airports for traveller and aircraft handling, ticketing and other services that management believes can be more cost resourcefully provided by third parties. Management attempts to obtain competitive rates for such services by negotiating multi-year contracts at prices that are fixed or subject only to periodic increases related to inflation. One of the typical example is the price of aviation fuel which is directly related to the cost of oi l but Ryan air control this through hedging.All these factors listed above contributed to a low variable cost of Ryan air, a key component in any successful yield management system and provide an opportunity for leverage against its major competitors.3.

Extracorporeal Membrane Oxygenation (ECMO)

Extracorporeal Membrane Oxygenation (ECMO)Cardiovascular DevicesChiara TarenghiWhen a patient suffers from critical conditions which prevent to lungs or heart to work properly and to grant adequate blood flow and oxygen supply, either because of infixed disease, surgery or other reasons (severe pneumonia, sepsis, heart malformations, congenital diaphragmatic hernia, Respiratory Distress Syndrome ), a mechanical circulatory bear out is needed to take over temporarily the cardiopulmonary functions. These devices are known as extracorporeal smell support (ECLS).ECMO is an invasive, non-therapeutic technique, consists essentially of an artificial external lung, a tissue layer oxygenator, which reproduces the physiological function of the gas exchange in the lungs (the blood releases CO2 and gains O2 according to the fond(p) pressure gradient). It has successfully been employed as a bridge to recovery, cardiac transplantation, or implantation of a ventricular assist device, and it has met great application in paediatric surgery field (i.e. premature infants). It grants a steady amount of oxygen to the body while resting and recover the lungs and heart.The device pumps blood from the body by the oxygenator with a roller pump (or a centrifugal pump, which causes major haemolysis though). There are three types of oxygenator commercially available bubble oxygenator ( the gas is bubbled into blood), membrane oxygenator (allows exchanges of diffusion through a permeable membrane of silicon rubber that completely separates gas and blood), and hollow fibres oxygenator (fibres of PVC or PTFE hollow inside and semipermeable to gases).The blood is because warmed up through a heat exchanger (a coiled tubing containing warm water flowing counter current) and is injected adventure into the body. Each section of the machine is connected through seatnulae. The blood flow is monitored continuamente to avoid the presence of microscopic air bubbles, thrombi and other emboli. Hazardous occlusions of tubing or thrombosis are detected by pressure monitors.Before letting blood flow through the tubes, the latter are primed by flushing with CO2 and then with crystalloid prime, albumin (to limit platelets adherence) and finally blood. The flow and amount of oxygenation is adjusted according to the needs of the patient. As the heart function improves, the flow is lowered. Blood volume can be assessed by urine output and central venous and mean arterial pressure. After a few days of mechanical assistance, the device is normally removed.ECMO is a valid alternative to pulmonary ventilation, since the latter pushes oxygen into patients lungs, regulating its amount and pressure, but high gas pressure could further damage lungs. Risks associated to ECMO take on blood clot formation (which is prevented through anticoagulant like heparin) and, related to this, haemorrhage, infection, transfusions problems (thromboembolism and related stroke or ischaemia), mechanical failures.There are different ways of perfusion ECMO VENO ARTERIAL (VA) It requires three tubes to be inserted, venous blood is removed from the right atrium or vena cava, passing through the jugular or femoral vein, and returned to ascending aorta (central ECMO) or femoral artery (peripheral artery).It is a hemodynamic and respiratory support for patients suffering from cardiogenic shock, sepsis, severe pneumonia, persistent pulmonary hypertension.Advantages Low cost, can be applied to children and adults, support double heart and lungs. Disadvantages It is more invasive than VV ECMO is a complex circuit, can cause embolism, neurological complications and require a sternotomy.ECMO VENO VENOUS (VV) In this case devil tubes are inserted into the largest veins as jugular or femoral, but most often a single Y shaped cannula is inserted in the both veins. Blood is beat(p) from the vena cava , blood is returned through the right atrium into the tricuspid valve.It is only a respirator y support for patients suffering from severe respiratory failure, asthmas, persistent pulmonary hypertension. Disadvantages No cardiac support.ARTERIO VENUS (AV)uses patients arterial pressure to pump the blood from artery to vein, it can be used only as a short-term support.
