Vitamin C lab report free essay sample

Vitamin C, also called ascorbic acid, is a water soluble vitamin. It is a powerful reducing agent that is able to decolourise blue DCPIP (2. 6-dichlorophenol indophenols). The decolourisation of DCPIP can therefore be used to calculate the vitamin C content of a variety of fruit juices. Research Question – To determine how the content of Vitamin C (%) will differ in fresh fruits (orange, mango, lemon, lime, blackcurrant, pineapple) from that in processed fruit juices (orange, pineapple) by adding drops of the aforementioned fruit juices to DCPIP until the DCPIP gets decolorized. Variables Independent Variable – Type of fruit juice used (fresh or processed). NB: the juice from the fruits was freshly squeezed during the experiment. Dependent Variable – Amount of fruit juice it takes to decolourize the DCPIP in cm3 (Â ±0. 2cm3) Controlled Variables – 1) Concentration of DCPIP was the same in all the samples. A larger amount of it was prepared for this case. 2) The same amount of DCPIP was added in each test-tube (1 cm3) using the same 5cm3 syringe 3) All the fruit juices, fresh and processed, were diluted five times. We will write a custom essay sample on Vitamin C lab report or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The same 5cm3 syringe was used to add drops of fruit juices in the test tubes 5) State of decolourization – one sample of decolourised DCPIP was used as a basic one (one with 0. 1% ascorbic acid) and later all the fruit juices with DCPIP were compared with the sample. The decolourization should have been the same in both the samples. 6) The other control was similar to (5) above, but instead of having ascorbic acid, it had distilled water. It was used to show that only vitamin C can decolourize DCPIP Materials 10 Test Tubes 2 x 5cm3 syringes (Â ±0. 2cm3) (pipettes were not available so syringes were used) 3 x 20 cm3 beakers Label the test tubes, then slowly pipette 1 cm3 of DCPIP into each test tube Safety! – DCPIP is corrosive and toxic. Wash of any spills with water 2) Take 5cm3 of 0. 1 % ascorbic acid using a syringe 3) Add the ascorbic acid drop by drop into the first test tube, gently shake the tube after each drop is added. As soon as the DCPIP becomes decolourized, note the volume of ascorbic acid that was added 4) Wash syringe and beaker. Into the second test tube, add the same volume of distilled water as ascorbic acid that you added in test-tube 1. Gently shake the tube and note observations. 6) Dilute all juices to be tested 5 times using a measuring cylinder. 7) Add the first sample of juice drop, gently shake the tube after each drop is added and note the volume added in order to decolourize the DCPIP. Continue the same way for other fruit juices Do not forget to wash out the beaker and the pipette after each juice is used 8) Lastly, calculate the concentration of ascorbic acid present in each fruit juice: Data Collection – Qualitative – Table 1: Colour change in each liquid test Tube Liquid test Colour 1 0. 1% ascorbic acid (control) colourless 2 Distilled water (control) No change 3 0range juice(fresh) colourless 4 Lemon colourless 5 Mango colourless 6 Lime colourless 7 blackcurrant magenta 8 pineapple colourless 9 Processed orange juice Turns light purple/maroon 10 Processed pineapple juice Pink From the table on the previous page it can be seen already that most fresh fruit juices have high amounts of vitamin C as they completely decolourise the DCPIP (comparing to test tube 1 which is the control). Moreover, both of the processed juices seem to have lower amounts of DCPIP as they hardly change from their original colour (purple). None of the final colours were similar to that with distilled water, showing that all of them had some amount of ascorbic acid. Quantitative Data In the following table, the test-tube with distilled water will not be taken into account as the DCPIP was not decolourized. Table 2: amount of volume required to decolourise DCPIP in each liquid test Tube Liquid Test Volume (cm3/(Â ±0. 2cm3) added to decolorize DCPIP 1 0. 1% ascorbic acid (control) 0. 6 3 0range juice(fresh) 2 4 Lemon 3. 1 5 Mango 3 6 Lime 2. 9 7 blackcurrant 18 8 pineapple 6 9 Processed orange juice 20 10 Processed pineapple juice 18 The data in this table supports the qualitative results. It should be noted that due to time constraints, for test-tube 7, 9 and 10 the experiment was stopped as they didn’t change colour quickly and continuing the experiment would have been time consuming. The fact that they decolourised from their original colour was taken as proof that ascorbic acid was present. Data Processing Using this formula the concentration of ascorbic acid in all the liquids was found Volume of 0. 1 % ascorbic acid is 0. 6 cm3 (Â ±0. 2cm3). Table 3: Concentration of ascorbic acid (%) in liquid tests Tube Liquid Test Volume (cm3/(Â ±0. 2cm3) added to decolorize DCPIP Concentration of ascorbic acid (%) 1 0. 1% ascorbic acid (control) 0. 6 3 0range juice(fresh) 2 0. 03 4 Lemon (fresh) 3. 1 5 Mango (fresh) 3 6 Lime (fresh) 2. 9 7 Blackcurrant (fresh) 18 8 Pineapple (fresh) 6 9 Processed orange juice 20 10 Processed pineapple juice 18 Presenting Processed Data The following bar graph shows the amount of vitamin C present in each of the liquid tests. It shows that test tubes 7, 9 and 10 have the least amounts of Vitamin C while from the fruit juices, test tube 3 has the highest amount of vitamin c. Note: test tube 1 is a control with ascorbic acid (0. 1%). Graph 1: Concentration of Ascorbic acid (%) against fruit juices From Table 3, it can be seen that greater the volume of liquid required to decolourise the DCPIP, smaller the concentration of ascorbic acid (%) in the solutions. The following graph shows this relationship even more clearly. The plots were joined using a trend line so that the trend can be seen more clearly. Graph 2: Concentration of ascorbic acid (%) against Volume (cm3/(Â ±0. 2cm3) added to decolorize DCPIP The following graph shows that the concentration of ascorbic acid (%) in the fresh fruits (indicated by the blue diamond-shaped dots) is higher than the concentration in processed fruit juices (indicated by the blue squares). All the points in the fresh fruits line are higher than those in the processed fruit line. Since we could not get the processed juices for all the fresh fruits, the following graph will focus on the vitamin C concentrations of orange and pineapple, both fresh and processed. Graph 3:Fresh orange and Processed orange Graph 4: Fresh pineapple and Processed Pineapple Juice This clearly shows that there is a higher vitamin C concentration in the fresh fruits (3 and 8) than in the processed fruit juice (9 and 10) Conclusion Putting the above results from highest Vitamin C concentration to lowest; Ascorbic Acid (1st) Fresh Orange Juice Fresh lemon Fresh Mango Fresh Lime Fresh pineapple Fresh Blackcurrant Processed Orange juice Processed Pineapple juice Distilled water (last) From this ranking, it can be said that from the fruit juices/ Fresh orange juice (0.03%) has the highest amount of Vitamin C and the processed fruit juices (orange, pineapple) have the lowest amount (0. 003%) Even though only 2 comparisons could be made (Graph 4 and 5), the results of this investigation illustrate without any doubt that fresh fruit juices(orange, mango, lemon, lime, blackcurrant, pineapple) have a higher concentration of ascorbic acid (%) than do processed fruit juices (pineapple, orange). The research question can thus be answered as: the concentration of Vitamin C is higher in fresh fruits than processed juices. Therefore, if our diet consists more of the fresh fruits above, we will gain a higher amount of vitamin C in our bodies. Evaluation 1) Oranges are ranked as world’s healthiest fruits because of their high Vitamin C concentration. One orange has 69. 62mg of Vitamin C and can supply 116. 2% of the daily value1. This fact is consistent with the findings of the experiment, where the concentration of ascorbic acid in fresh orange is the highest from all the samples tested (0. 03%) 2) All the fruits used were fresh and bought on the same day. This increased reliability of the results since the age of the fruit may affect Vitamin C content. 3) Water was used as a control in the experiment to ensure the fact that only items with vitamin C can decolourize DCPIP. 4) A syringe was used to drop the fruit juices in to the test tubes since a pipette was not available. The problem with a syringe is that if too much pressure is applied, the entire solution can be poured out and it has an uncertainty of (Â ±0. 2cm3). Maybe it would have been better to use a burette, which also has a lower uncertainty (3) 5) We were told that the concentration of ascorbic acid provided was 0.1%. We were not however sure because we did not see it being made. In this case, we should have made the solution to that concentration ourselves, or the lab technician should have made it in front of us. 6) A limitation of this investigation was that the maturity stage of the fruits was not determined. Vitamin C concentration decreases during the ripening process. Unripe fruits have more ascorbic acid than the ripe ones. Since the ripening stage was not informed, the ascorbic acid concentration could have varied and therefore affected the results of the experiment. Even the position of the fruits on the tree was not known; sunlight exposure enhances vitamin C levels. Maybe some fruits were on the shadier side showing low levels of vitamin C. 7) The observations in this experiment were made solely by the eye. There was thus huge room for human error, as sometimes, two drops could seem one drop. In this case, two people could have been used to watch the drops and increase reliability of results 8) Blackcurrant is a fresh fruit which has a very high concentration of vitamin C. However the results of this investigation showed otherwise. This may indicate a shortcoming in the experiment because this fruit was the only one which did not show a high concentration of vitamin C. Maybe the juice became a bit too dilute. This could have been rectified if time had allowed. Due to time constraints, this experiment was only carried out once. In order to obtain reliable results however, the experiment should have been carried out three times, and the average volume of liquids required to decolourize could have been obtained, giving a more realistic picture of the concentrations. Another limitation was that besides orange and pineapple, the processed juices of other fresh fruits were not available and so they could not be directly compared to each other. However, the results did show that processed fruit juices had low Vitamin C content. 10) If time would have permitted, the experiment for 7, 9 and 10 should have been continued so as to obtain the exact end point when the DCPIP got decolorized and therefore get the exact concentration of ascorbic acid (%) in those liquid tests.

just wait Essay just wait Essay Just Wait So many of our young children are having babies when they’re just babies themselves. Teenagers do not realize the consequences of bringing a life into this world. There are so many responsibilities and hardships to having a baby that our young people do not realize till it’s too late. Television and social media make having a baby look fun and easy, but in reality there is much more to it. They do not reveal the night time awakenings, crying, cleaning duties, and all the other difficult duties that come with having a baby. Sure babies are cute and lovable, but they are defiantly a responsibility for adulthood. Children’s small bodies are just not equipped to birth a child when they are that young. There body is not done growing and it is just not healthy to put your body through such trauma. Women’s hips are not spread and her body is not developed enough to birth a child. In 2011 329, 797 babies were born from children; live births in America ha ve gone down 8 percent from 2010. Only 50 percent of teen moms finish high school, and 90 percent of teens under 16 years will not finish. Teen parents are also less likely to go to college which decreases their job rates and makes your income low. You cannot give your baby all you want to give when you’re not financially stable, it is more logic to wait and become stable before adding an extreme expense to your budget. Fathers of babies are less likely to be involved as a teen. Boys maturity level is much lower than girls, and they are not forced to stay and carry the baby like the girls. So not only do teen moms have to raise a child and take on a huge

Nursing shortage and its effects on the provision of health care Term Paper

Nursing shortage and its effects on the provision of health care - Term Paper Example Despite renewed efforts at reform in most European countries, the number of uninsured people continues to grow, the cost of healthcare continues to soar, and the safety and quality of care are queried. The great challenges of the healthcare system need significant attention on the part of health experts, policy makers and the society. One problem that has continued to dog the health care sector over the last five years has been the perennial shortage of registered nurses as well as other health care professionals as a demonstration of the fragility and faults in the health care system. For health care delivery to be efficient, reasonable, and inexpensive, there must be an ample stream of knowledgeable, well spread and employed certified nurses. While the general quality of care seems to have responded progressively to the rising emphasis on evidence-based practice and performing procedures, major inequalities in quality stubbornly persist. The health care system and the nursing profe ssion are once more witnessing a shortage in nurses that is augmented by shortcomings of the system and the ever-rising need for health care, as the baby boomers grow old. The intricate environment of challenges of the health care system requires major attention on the part of health care professionals, policy makers and to a smaller extent the public.In all the health care literature available today, the widely accepted elements of health care reform are the ability to get health care, its quality, cost, and the workforce.

Marketing - Essay Example This shows that company is struggling with its marketing functions, but is still recording a below the industry’s average performance. It still requires the company to put much more efforts on marketing to improve on its marketing performance. The business strategy in the 2nd year could possibly have been that of investing its finances on the future performance of the company as well as improving its effectiveness in marketing. It is very evident that the company achieved the highest in performance of the industry performance on marketing effectiveness with 0.80 performances which is also the industry highest performance. This shows that the company employed a lot of its efforts on the marketing strategies so as to improve its market share as well as competitiveness and create market awareness among other marketing functions. On the other hand, out of the possible maximum company performance on investment in the future of 2.24, the company was able to score way above the industry average and almost the reaching the industry highest by scoring 2.14. This shows that the company is much concerned about the going concern of the company and would like to see the company stand even more firm in the future than the today’ s company’s creation of wealth. This is even why the company’s wealth performance is very low since it ploughs-back much of its profits into future

Will business save the planet - Essay Example In the recent decade, energy requirements have risen considerably (Economic Intelligence Unit). More important is the conservation of energy to secure the safety and energy sustainability of its future generation. This entails utilizing renewable energy sources that do not contribute to pollution (reasons for using renewable resources). Complete utilization of renewable energy sources, as opposed to non-renewable sources will ensure pollution emissions are reduced to minimum levels thereby conserving the ozone layer (HAVC System). One of the development objectives of China is to foster the growth of wind and solar companies (ACORE). Non-renewable energy is bound to get depleted in the near future. Investing in the non-renewable energy is an appropriate method to alleviate the risk of running out of non-renewable energy. Hence China has secured its place as the world leader in growing its green energy. Approximately a quarter of the world green energy is found in China. Between 2005 a nd 2010, wind turbines have been constructed at a fast rate in China (Economic Intelligence Unit). China has established itself as an â€Å"economic superpower† and is also striving to be the world leader in utilizing green energy. China is no doubt becoming the world’s leader in the exploitation of green energy sources. While, the USA, which is the current leader in green energy investment, is losing momentum in investing in green energy, China is making big strides in exploiting green energy. Hence China is bound to be ranked number one in tapping and exploiting green energy resources. These vibrant efforts made by China have caught the attention of investors like Bloomerg New Energy Finance and Germany among other investors, which contribute to China’s green energy capital (Silverstein 1). China’s efforts to strive to be a leader in utilizing green energy have been become apparent to international stakeholders who can assist China to achieve its energy goals. This assistance could be in the form of financial support or technological research on how to convert green energy to a usable form. In a bid to further its green energy agenda, China is getting rid of companies that utilize non-renewable energy resources. Between 2005 and 2010, China decommissioned power companies that were inefficient in terms of power consumption and this trend is also set to continue. China is also abolishing those companies that contribute to air pollutant emissions (â€Å"China’s action on climate change,† 1). Abolishing companies that utilize non-renewable energy sources is a sure way to minimize pollution emissions and attain total green energy dependence. Among the green energy conversion technologies that have gained the most recognition in terms of financing include solar power technologies with the top markets being China, Europe and the United States. However, the United States is losing its grip as the world leader in attracting i nvestments for green energy due to lack of governmental commitment in green energy efforts (Silverstein 1). This shows that China is committed to converting to green energy exploitation. This is shown by the enormous financial investments it is the direction towards green energy. Such is the commitment that will set at the top of the list of the world’s leaders in green energy investment. Other countries that have shown considerable efforts in investing in green energy include Italy, Brazil and India (Silverstein 1). The future of Green Energy in China In China’s 12th 5 year plan, the reduction of carbon dioxide emissions was given priority, showing China’s change in attitude towards green ene

Ryanair Case Study

Nova School of Business and Economics 2012/2013 DOGFIGHT OVER EUROPE: RYANAIR Case Study This set of questions refers to Version (A): 1. Which kind of customers was Ryanair trying to attract when, in 1999, Michael O’Leary took charge of the firm? Those with a low price elasticity of demand or those with a high price elasticity of demand? Explain.Considering that we are talking about the same product, in an industry with many firms, where producers and consumers know all quoted prices and where the consumers can identify the product as homogeneous, it is fair to say that we are talking about a scenario close to perfect competition, thus demand for the product is very elastic. So, Ryanair is trying to attract high price elasticity customers.Accordingly to the article: Ryanair marketed itself as â€Å"the low fares airline†; before open new routes, the company cared about low landing fees, low turnaround costs in order to be able to charge low fares to customers; it made a greements with secondary airports, where they did not pays fees (in fact those airports paid to Ryanair to use their locales); it tried that 70% of the available seats in the two lowest fare categories; it made fewer restrictions on its tickets (important for who had extra bags, or who wants to change the flights in order to pay less); it observe competitors, so it would be able to apply a lower fare; its customers were a mix of leisure travelers (70-75%) and business travelers, mostly from small and mid-sized businesses (25-30%). ifferences in airfares could persuade some leisure travelers to visit one destination rather than another; it has chosen the cost leadership so it seeks to be the lowest cost producer in Europe by selling standardized, mass products and Ryanair’s profit maximization was through lower fares in order to attract more customers contrarily to competitors where they maximize their profits through find opportunities to increase fares without losing custome rs. So accordingly to the customers with a high PED (price elasticity demand) following the formula (Q/P) x (P/Q): a little negative variation in prices (decrease in fares), will originate a big positive variation in the amount sold. 2. Why was cost cutting so essential for the strategy chosen? First of all it is important to refer that in 1991, Ryanair was facing a bankruptcy.In response, ‘the company removed all frills from its service, cut its costs to the bone, and dropped its fares to levels unheard of in Europe’. It became priority, to connect all the efforts to preserve and generate cash. Company’s main concern was charge lower fares in order to attract high elasticity price demand customers, with this new strategy, the company became low-cost or low-fare airlines and to maintain it within these measures the firm needed to adapt its strategy to new restrictions, which means, cost cutting. The flag airline faced a really competitive market (in 1999), and to keep competitive the firm had to keep its strategy, and for that was necessary cost cutting. Cost cutting, if it is efficiently done, brings more profits.Besides, using the model used in classes, â€Å"Bertrand – Asymmetric Model† where it says that if certain firm charges ‘P1’ for its product, and other firm charges ‘P1-e’ (because it is able to reduce its marginal cost), so the second firm will get all the demand. Well, Ryanair did not get all the demand, but is observable in ‘Exhibit 4’ that the company carried approximately 60% (353/575) and 56% (180/321) of the passengers on the route ‘Dublin-Manchester’ and the route ‘Dublin-Glasgow’ respectively. 3. Ryanair uses a performance-based pay scheme to compensate its flight attendants. Why? A performance-based payment scheme combines the interests of both flight attendants and the company. This happens because obviously, the flag airline will gain more i f the attendants are working efficiently (making an effort to sell the snacks, drinks, or whatever they have on board; being nice with the passengers, and help them as much they can), then if they are lazy during work. If a salesperson receives a fixed wage, no matter how much it sells, then he or she will not have any incentive to sell more than the expected. But, of course, if they receive an extra commission for each sale, then the salesperson will do the effort that it maximizes its utility. By having a higher effort, the workers have a higher payoff which maximizes its utility.A sector payment or an in-flight sales commission allowed flight attendants to earn 10% more than those from competitors and allowed the firm to fly to 50% more sectors than its rivals. Consequently, a higher number of flights increase the profits of Ryanair. The company’s rapid growth permitted job mobility, for instance, a flight attendant could take a job at the yield operations management on th e headquarters; job mobility was a solution for the company to avoid coordination problems. 4. Why wasn’t this performance scheme also offered to maintenance personnel? The majority of European airlines pay their employees based on the length of their tenure with the company. However, Ryanair only applied this to their maintenance and engineering personnel.As a company obsessed with cash, the most important part of the business was the operational part, the one which actually gave money to the company: flights and duty-free revenues. So, this was the only personnel where it was justifiable to apply a performance-based pay scheme. Engineering and maintenance were paid based on their formal qualifications: more qualified personnel would do the job more accurately. Maintenance personnel only represented 9,34% of the total employees as of March 31, 1999. Besides the company concerns about security: let’s say that if they receive a fee for each plane that is ‘fixedâ⠂¬â„¢, they will want to fix the maximum planes, as fast as possible, and that may not be the best for the passenger’s security.It’s more important to seek personal with higher qualification, and pay them a reasonable (but fixed) salary, because this is kind of business where mistakes cannot happen, and so, the personnel has to be focus in its work, and not in the ‘extra money’. 5. Can you suggest means of rewarding maintenance personnel that would induce high productivity without hindering Ryanair’s strategy? Ryanair’s strategy is keep low fares so it will be able to keep â€Å"fiercely competitive† and â€Å"ferociously cost conscious†, which implies, minimize costs (everywhere where it is possible), so increase their salaries would hurt the company’s strategy. Given this, it would be a good idea to search for some ‘non-monetary’ alternatives.First of all give them some lectures about how important is to do a good maintenance of the aircraft, aware them that a single mistake can be fatal for hundreds of people (unless they are murderers or mentally sick people they will get alert! ). They can make promises to them in the long-run like if there are no mistakes, Ryanair’s credibility increases, and that will attract more passengers, which means more revenues, which means they can increase wages (and keep the same profit). Monitoring them is a good way of keep the high productivity, this measure leads to an increase in veracity of the employee's reports, in other words, if an employee knows that he or she is being watched, then it will for sure do a better job.The creation of bureaucracy that implies the creation of rules in order to limit the employee’s actions, these rules can be benefit for the maintenance workers, for example, the creation of a rule that says it is mandatory to do a 15 minutes break, every two hours. 6. What are the likely consequences for Ryanair of a steep decrease in the price of jet fuel brought about by a significant decline in the price of oil? Consider both the direct and the strategic effect. All the airline companies are strategic complements, which mean that if one firm takes one action, the others will respond with aggressively actions (upward sloping). And they exhibit tough commitment, in other words, is a commitment that is going to have an adverse effect on the competitors.In Bertrand (this case), the company makes a tough commitment, no matter how much its rival changes the price, the firm’s price will be lower than it would have been if there were no commitment. The companies make tough commitment to avoid that new entrants increase the price competition. Given this, we built the following graph: The red line stands for direct effect and the blue line stands for substitution effect. The direct effect is the commitment’s impact on the present value of the firm’s profits, assuming that the compe titors’ behavior does not change. Applying to the case is basically the profits that all the others airline companies would earn if Ryanair would not decrease its prices as well (point 1 to point 2).The substitution effect takes into account the competitive side effects of the commitment, this means, how much does the tactical decisions of the rivals change, under the commitment conditions. Basically is the adjustment made by Ryanair after the competitors decrease their prices (point 2 to point 3). Decline in the price of oil, brings a decrease in the price of jet fuel. With this shock, all the airline companies will decrease their prices, P1*’. As it was said before, Ryanair always observes its competitors, and then make its move, so they will decrease their tickets’ prices even more, P2*’(one of the principals of tough commitment). As it says in exhibit 2, ‘fuel ; oil’ constitutes approximately 16% of its costs (6. 0/37. ), so despite it is not visible on the graph (due to lack of data related to prices), the prices of the flight’s tickets will decrease considerable, because (repeat) this is a really competitive market, and the airline companies find themselves in a tough commitment, that it will originate a decline even bigger that the one it would happen without though commitment. It is important to refer that the company’s product has a low-level of horizontal differentiation because the difference between the products of each one of the companies is based on the quality in the in-flight zone. And there are tons of people who simply do not care about that.For those ones, their only concern is to get to their destination. 7. What are the most serious threats that Ryanair faces? Explain your perspective. Europe Union’s measure â€Å"Under the package, carriers were given full freedom to set fares. Any company was allowed to start an airline provided that it had majority European ownership, adequ ate financial backing, and the ability to meet safety requirements. The package permitted any European airline to fly any route between two EU countries and, starting in 1997, any intra-country route between two European cities. † This measure means no patents’ system, which means that as long as there is positive profit, other companies will enter in the market.Without proper cautions this may lead to perfect competition, where the companies will lower their prices until it equals the marginal cost, which implies that the profit will be zero. Even worse than that is if Ryanair adheres to a new technology (in order to decrease its marginal cost), and if we are in a situation where the other companies can copy and use the technology discovered by Ryanair, the company will have negative profits. Contrarily if the competitors are able to decrease its marginal cost, and the antitrust agencies that may lead to monopoly (if there is a patented system that says that is illegal to copy and use technology of others firms). Possible merges by competitors, which would increase their market share. For example, in 2002, easyJet purchased Go for ? 374m.Ryanair may face laws taken by the antitrust agencies that may limit its actions, for example the use of ‘dumping’ strategy (‘monopolistic strategy’ where the firm sells its products below their production cost in order to eliminate competition, and when it occurs, the firm increase its prices again). Ryanair has faced aggressive marketing campaigns and charity efforts by Virgin Express, subcontracts and reliability on third parties (lower costs), total direct selling and a very informal environment by easyJet, predatory pricing by British Airways’ Go and in-flight entertainment and comfort by Debonair. The last one went bankrupt but all the others provide serious competition to Ryanair despite not achieving the profitable results desired.
