The Beer Process Essay Example For Students

The Beer Process Essay The dried grain kernels need to absorb moisture in the softening House so that the barley can germinate. This process takes 50 hours. Throughout this time the barley is aired and washed using pumps. Through the water separator, the barely dives as the brewers like to say into the softening vat. Round softening vats and water separation prepare the grain during the even and slow insertion of the barley. (Picture 2/3). In every beer, the most important ingredient is malt. Bottom fermenting beers uses barley malt, while top fermenting beers allow the use of other malts. For example, in addition to barley malt, wheat malt will be used. In Athenian Brewery S.A, special malting and brewing barley types have been germinated and cultivated. Important to the barley cultivators are full kernel, fine spelt (husks) and rich enzyme content. Most beer barley types have a lower yield than the barley that feeds animals. With their special ingredients, though, they reach a high yield during fermentation and add to beers noble taste. We will write a custom essay on The Beer Process specifically for you for only $16.38 $13.9/page Order now From Barley comes â€Å"Green Malt†Raw barley is not ready to be used in brewing. In order to unlock the hidden ingredients, it needs to be malted. To do this the barley, after being cleaned and sorted, is soaked for two or three days in a large vat full of water, where they swell and then begin to germinate. Germination enhancing chemicals are forbidden. The barley kernels soak up water quickly at the beginning, and then more slowly during the soak. With the proper temperatures and rich amounts of oxygen, the barley begins to germinate. Finally the barley is laid out for five days to germinate. With the right amount of air, it becomes green maltIn order to stop the germination, the malt is kiln-dried under high temperatures. Moisture, Temperature and the length of the drying process determine if light or dark malt (and with it the ingredients for lighter and darker beer styles) will be made and give malt its typical malt aroma. The finished brewing malt contains only 3 or 4% moisture and is now ready to be stored. It is cleaned and separated from the germinating malt, dusted and polished and then stored in silos that are well ventilated and protected from dust development. The germination sets biological changes within the kernel into action: Enzymes are activated or newly created. These developments are only interrupted by the kiln-drying. During the mash (the mixing of the ground malt with water) the enzymes as desired become active again. The malt is now ready for the brewing process. Production methods will differ from brewery to brewery, as well as according to brewery equipment and beer types. Athenian Brewery S.A uses its own production methods; however the main processes will be similar. The description below applies to the production of a typical lager beer in a brewery with a lauter tun installed. The first stage in the brewing process is the preparation of the wort. After the malt is crushed to grist of suitable fineness, and preliminary treatment of the adjuncts takes place to facilitate extraction, the malt and adjuncts are mixed with brewing water to form a mash. Adjuncts are a supplementary sugar supply, provided either as starch (e.g. maize grits or rice) or as sugar or glucose syrup. Glucose syrup can also be added later to the wort kettle. The mash is heated, following a pre-set time-temperature program, in order to convert and dissolve substances from the malt and adjuncts in the brewing water. (The brewing water is often called ‘liquor’.)Extraction is accomplished through a combination of simple dissolution and the influence of the enzymes formed during the malting. The substances dissolved in the water are collectively called the â€Å"extract†. The solution formed is called the â€Å"wort†When the mashing is completed, the spent raw mater ial, called the â€Å"spent grains†, is separated from the wort by straining. The wort is then boiled with hops or hop extracts, releasing bitter substances and oils which are dissolved in the wort. During boiling the bitter substances are isomerizes, which increases their solubility, and a precipitate consisting mainly of proteins is obtained (the â€Å"trub’). After separation of the trub, the wort is cooled to approximately lO0C. The cooled wort is transferred to the fermentation area. In order to obtain a high yield of extracted substances as quickly and efficiently as possible, the malt must first be crushed before being mixed with hot water. Care should be taken during crushing to make sure the husks are not damaged, since they are used as filter bed for separating the spent grains when straining off the wort. Since the extract yield generally increases in direct proportion to the degree of fineness to which the malt is milled, it would be preferable for the malt to be crushed to very fine flour. However, this would cause the filter bed to become clogged during most wort straining operations, resulting in an increase in the time required for separation. Moreover, the bed would become less permeable, leading to the hold-up of valuable extract within the spent grains. Spargin2, if used, would also be less effective in recovering extract. The fineness to which the malt is milled is therefore a balance between best extract yield and ability to filter the wort. The purpose of mashing is to obtain a high yield of extract (of the highest possible quality) from the malt grist and adjuncts by extraction in the brewing water. Only a minor part of the extract is obtained through ordinary dissolution, while the remainder is extracted by means of the enzymatic breakdown of complex insoluble substances to simple water-soluble substances. Factors such as temperature, PH and length of time of the mashing must be carefully controlled so as to create optimum conditions. Conversion temperature is typically 650C, but mashing may begin at lower temperatures (e.g. 45OC) if the malt is relatively tinder-modified. .u80f5c5d3dabf46a78a39b7353e263eac , .u80f5c5d3dabf46a78a39b7353e263eac .postImageUrl , .u80f5c5d3dabf46a78a39b7353e263eac .centered-text-area { min-height: 80px; position: relative; } .u80f5c5d3dabf46a78a39b7353e263eac , .u80f5c5d3dabf46a78a39b7353e263eac:hover , .u80f5c5d3dabf46a78a39b7353e263eac:visited , .u80f5c5d3dabf46a78a39b7353e263eac:active { border:0!important; } .u80f5c5d3dabf46a78a39b7353e263eac .clearfix:after { content: ""; display: table; clear: both; } .u80f5c5d3dabf46a78a39b7353e263eac { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u80f5c5d3dabf46a78a39b7353e263eac:active , .u80f5c5d3dabf46a78a39b7353e263eac:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u80f5c5d3dabf46a78a39b7353e263eac .centered-text-area { width: 100%; position: relative ; } .u80f5c5d3dabf46a78a39b7353e263eac .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u80f5c5d3dabf46a78a39b7353e263eac .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u80f5c5d3dabf46a78a39b7353e263eac .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u80f5c5d3dabf46a78a39b7353e263eac:hover .ctaButton { background-color: #34495E!important; } .u80f5c5d3dabf46a78a39b7353e263eac .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u80f5c5d3dabf46a78a39b7353e263eac .u80f5c5d3dabf46a78a39b7353e263eac-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u80f5c5d3dabf46a78a39b7353e263eac:after { content: ""; display: block; clear: both; } READ: Inline or Online EssaySome classes of proteins and starches are insoluble in water. During mashing, the proteins are broken down by an enzyme system. Proteases hvdrolyse the proteins to peptides and other less complex nitrogenous compounds, and peptidases subsequently break down the peptides to amino acids. The starch is broken down by the amylase enzyme system to glucose, maltose and dextrins. In case of poor malt quality, enzymes from the malt can be supplemented with exogenous enzymes. Adjuncts such as rice and maize are not pre-germinated and do not contribute enzymes. Furthermore, their starch has a higher gelatinization temperature than malt starch. The adjunct is therefore mixed with water and cooked. The adjunct mash is then mixed with the malt mash and the malt enzymes break down the adjunct starch. Sugar and glucose syrup can also be used as adjuncts. Since no enzymatic breakdown is required, these adjuncts are added to the wort kettle. During mashing, the substances in the malt and adjuncts are broken down and dissolved in the brewing water. In addition to sugar and protein compounds of various complexities, the mash also contains insoluble material (spent grains). The wort is separated from the spent grains by straining through a porous filter bed formed by the husks. The residual extract in the filter bed is leached out with sparging water. The temperature of the wort during straining is about 75-780C. Following removal of the spent grains, the wort is heated to boiling in the work kettle and addition of the hops takes place. I.All enzymes are inactivated to prevent the continued breakdown of proteins during fermentation. 3.Bittering of the wort occurs via isomerisation of hop alpha-acids. 4.Unstable colloidal protein coagulates and precipitates. 5.Unwanted flavour components evaporate from the wort. The wort is normally boiled vigorously for about I.5 hours with a minimum boiling intensity of 5-8% evaporation per hour. The degree of wort clarity required depends on the type of beer being produced and on brewing practices. The wort should be clear and free of particles â€Å"hot trub† ) before entering the fermenting vessel. Particles, especially small ones, carry lipids which in high concentration have a marked influence on the formation of ester and higher alcohols, as well as the production of other flavour components from yeast during fermentation. The equipment most commonly used for wort clarification is the whirlpool, in which the wort and trub particles are introduced in a tangential mode. Secondary forces on the particles cause them to migrate and accumulate in a cone at the centre of the bottom of the vessel. After clarification, the wort is cooled to a temperature of typically about 10OC. Cooling normally takes place in a heat exchanger. The hot water produced is collected and used as brewing water. After the wort has been cooled to the fermentation temperature, oxygen is added. The wort is then pumped to the fermentation tanks, where yeast is added. Oxygen is necessary to support development of the yeast to a state and amount capable of fermenting wort efficiently. Fermentation is an anaerobic process: the yeast metabolises the fermentable sugars in the wort, forming alcohol and carbon dioxide. Heat is generated during fermentation. To maintain the desired fermentation temperature, the fermentation vessels must he cooled. Once primary fermentation has occurred, the yeast is cropped and pumped to storage tanks. During fermentation, yeast is produced in excess. A part of this yeast is reused for a new hatch of wort, the remainder being discharged or treated as a by-product. The production yeast is typically reused several times (perhaps up to ten generations). The yeast treatment involves the following functions:†¢ Yeast propagation, i.e. production of new yeast†¢Storage and discharge of surplus and spent yeastThe beer is stored for a certain period following primary fermentation. The objective of storage is to obtain:†¢Settling of yeast and other precipitatesAfter storage, the beer is ready for filtration. For beer with a very high yeast cell count, a centrifuge may he necessary for pre-clarification prior to filtration in order avoid blockage of the filters. Installation of a centrifuge may further reduce the consumption of kieselguhr, the filtration medium. The cooling of beer prior to filtration is important in regard to shelf life, since a forced precipitation of haze particles takes place at this stage rather than hater in the bottles. Cooling must be controlled very carefully to ensure a constant beer temperature of approximately -10C to -l.5C. The purpose of filtration is to obtain the specified low level of initial haze in the beer and to facilitate prolonged shelf life. Filtration typically takes place in a kieselguhr (diatomaceous earth) filter. Perlites (volcanic residues) are sometimes used instead of kieselguhr. Diatomaceous earth performs the filtration, with the filter itself acting as support for the filter cake. The small diatoms form a rigid but porous filter cake which sieves out particulate matter as it passes through the filter. To prevent â€Å"blinding† of the filter, and to achieve extended filter runs, kieselguhr is continuously dosed into the unfiltered beer as â€Å"body feed†, thereby constantly building up the depth of the filter cake. To act as a â€Å"police filter† after the kieselguhr, a cartridge filter or sheet filter can he installed. Additives such as stabilising agents, colouring and primings (sugar) can be dosed to the beer. In order to achieve the finished product specification for CO, the beer is carbonated before being sent to the bright beer tank. Nitrogen gas may also be used in small quantities to favour foam performance. When the filtration process is completed, the beer is ready for packaging. Prior to packaging, the beer is stored in bright beer tanks. It is important that all process equipment and pipes are kept clean and disinfected. Cleaning is done by means of CIP plants, where cleaning agents are circulated through the equipment or sprinkled over the surface of the tanks. Disinfection takes place through a combination of high temperature, cleaning agents and disinfectants. Caustic and/or acid are normally used as cleaning agents. The cleaning and disinfection of the brewery equipment can involve the use of substantial amounts of energy, water, cleaning agents, and disinfectants. .u3f6db099eabce24d308cebc9da6b6552 , .u3f6db099eabce24d308cebc9da6b6552 .postImageUrl , .u3f6db099eabce24d308cebc9da6b6552 .centered-text-area { min-height: 80px; position: relative; } .u3f6db099eabce24d308cebc9da6b6552 , .u3f6db099eabce24d308cebc9da6b6552:hover , .u3f6db099eabce24d308cebc9da6b6552:visited , .u3f6db099eabce24d308cebc9da6b6552:active { border:0!important; } .u3f6db099eabce24d308cebc9da6b6552 .clearfix:after { content: ""; display: table; clear: both; } .u3f6db099eabce24d308cebc9da6b6552 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u3f6db099eabce24d308cebc9da6b6552:active , .u3f6db099eabce24d308cebc9da6b6552:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u3f6db099eabce24d308cebc9da6b6552 .centered-text-area { width: 100%; position: relative ; } .u3f6db099eabce24d308cebc9da6b6552 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u3f6db099eabce24d308cebc9da6b6552 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u3f6db099eabce24d308cebc9da6b6552 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u3f6db099eabce24d308cebc9da6b6552:hover .ctaButton { background-color: #34495E!important; } .u3f6db099eabce24d308cebc9da6b6552 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u3f6db099eabce24d308cebc9da6b6552 .u3f6db099eabce24d308cebc9da6b6552-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u3f6db099eabce24d308cebc9da6b6552:after { content: ""; display: block; clear: both; } READ: ch 2 medical terminology- suffixes indicating diseases or abnormal conditionsSeveral CIP units are usually required in order to cover all the process areas in the brewery. From the bright beer tanks the beer is pumped to the packaging area, where it is bottled, canned or kegged. During this final operation it is important that:†¢The beer is prevented from coming into contact with oxygen:†¢No carbon dioxide is lost, as the beer was carbonated to specifications during beer processing;†¢The beer is not infected. (If it is infected, its shelf life will be reduced and the beer will have off-flavours). In packaging lines using non-returnable bottles and cans, the bottles/cans are only flushed with water before filling. The bottle washer consumes large quantities of energy, water, and caustic. Furthermore, substantial quantities of waste water are discharged. The use of non-returnable packaging material reduces consumption of energy, water, and caustic, therefore reducing waste water generation. If kegs are used, they are cleaned and sterilised with steam before filling. Before being filled with beer, the returned bottles are sent to a bottle washer which removes all impurities inside and outside. Inside the bottles, impurities include residual beer mould, cigarette butts, etc, externally; impurities may include labels, aluminum foil, and dust particles. Bottle washing is likely to consist of soaking, rinsing, sterilisation and re-rinsing. The bottles are transported on conveyor belts from the bottle washer to the filling machine. They are filled under pressure, according to the quantity of dissolved carbon dioxide in the beer. In addition to tilling bottles, the most important function of filling machines (which may take various forms) is to prevent oxygen coming into contact with the beer. After filling, the bottles are conveyed to the crowner, which fits them with crown corks. The sealed bottles are then conveyed to the tunnel pasteurizer. Beer is pasteurised to ensure a long shelf life, although there is increasing use of sterile filtration as an alternative. It is important that all micro-organisms capable of growing in the beer are destroyed. Pasteurisation guarantees practically unlimited biological stability. Two different methods are used for the pasteurisation of the beer: (a) Tunnel pasteurisation, during which the beer is pasteurised in bottles (or cans), i.e. both beer and bottle are pasteurised as a closed unit; (b) Flash pasteurisation, employing a heat exchanger in which the beer is pasteurised before it is put into bottles (or kegs). Following pasteurisation, the bottles are conveyed to the labeler. There labels and, in some cases, foil are applied. The bottles are now ready for packing in crates, cartons, or other forms of transport packaging. Packed beer is stored in the warehouse. It is important to store beer under cover, as sunlight destroys its quality. In some breweries there is a centralised warehouse where chemicals and other supplies are kept. Brewery laboratories vary considerably from brewery to brewery. Well-equipped laboratories provide quality control checks on all aspects of raw materials control and use, brewing, fermentation, storage, filtration and packaging. In addition, they can analyse consumer product samples, process water, cleaning water, effectiveness of cleaning procedures, waste water, etc. on a routine basis. Heat is supplied by a boiler plant, usually located on-site. It can take the form of steam or of water at high temperature. Boilers are normally fired by oil, natural gas or coal, or supplemented with biogas from the anaerobic waste water treatment plant. Process cooling is supplied by a central plant using reciprocating or screw compressors. It can be distributed via the cooling media (for instance, ammonia) directly or via secondary cooling media such as propylene glycol. Water can be supplied from wells or surface intake. If the water is supplied from its own intakes, it should be treated in conventional water treatment plants. Normally the water quality must, as a minimum, meet regulatory requirements for drinking water. The various water consumers in the brewery have special water quality requirements, typically that it be soft or chlorine-free. Softening plants are regenerated using either salt or acids. Activated carbon filters are normally used to remove free chlorine. Water consumption in breweries varies significantly. Many breweries have installed water reservoirs and use booster stations for local water supply. Athenian Brewery S.A uses its own supplies of water that are the same for all the beers that Heineken N.V produces. The CO2 generated during the fermentation process can be collected, cleaned, and then reused in the brewery. CO2 is necessary for carbonation and/or counter-pressure in tanks and bottles to prevent beer oxidation. Some breweries recover more CO2 than is needed for production, in which case the surplus can be sold. Some breweries use nitrogen instead of CO2 for counter-pressure in tanks and bottles. Compressed air is mainly used for instruments, actuators, pressurising of tanks, and possibly the transport of spent grain. Most breweries use public sources of electricity. A few have their own co-generation plants, producing both electricity and heat. If the electricity supply is not stable, emergency generators may be used. The existence of a waste water treatment plant will depend on local discharge requirements and the costs of waste water treatment. Relevant waste water treatment technologies involve neutralisation and anaerobic or aerobic processes. There may be a centralised workshop that machine-tools spare parts, maintains equipment and vehicles, etc. Or workshops may be located near various operations. Storage for auxiliary materials such as kieselguhr, glue, labels, etc. is ideally located near where the materials are used. Solid waste is normally collected in a solid waste area equipped with compartments or containers for each type of waste. Bibliography:

FROM THE EARTH TO THE MOON AND AROUND THE MOON essays

FROM THE EARTH TO THE MOON AND AROUND THE MOON essays FROM THE EARTH TO THE MOON AND AROUND THE MOON From the earth to the moon and around the moon by Jules Verne, a book about how he foresaw man reaching the moon. Through the infamous Gun Club which was nothing more than a group of disfigured and excitable old war veterans. Since there was no war, they needed to create some grand project as an outlet for their destructive energy. Illustrated in many of the attitudes of the Gun Club members was how they feared no obstacle and were confident that American resourcefulness would conquer all of their obstacles. One of the ways that they vented their destructive power was to build a projectile-vehicle to voyage around the moon and back. The members of the gun club were determined to build the vehicle that will bring them around the moon. They chose a crew of 3 to voyage on the projectile-vehicle, Michel Arden, President Barbicane, and Captain Nicholl. They all successfully made it around the moon but on the way back they had a little trouble and on re-entry to earth they didnt land quite were they wanted to. They ended up in the Mid-Pacific Ocean. The other members used all the latest equipment that was used to put the transatlantic cable in the Atlantic Ocean to get them out. At the end of the book after it kind of leaves you with a little of Jules Vernes food for thought, he asks if they would ever be able to colonize the moon, and move on colonizing planet after planet. Even then back 200 years we still have the dream of colonizing other planets and also our own moon. This book was exciting and captivating all at once. The book was exciting because you never knew what was going to happen. The book was captivating because you wanted to know what was going to happen. Both of them came from when they were at the bottom of the Pacific Ocean and you werent sure if The Gun Club was going to have enough influence to get them out of ...

The role of Arthur Miller in the development of The Crucible The Crucible deals with the main events of Salem and the main changes and developments of roles emerging in the play. Every character in the drama experiences some change whether it is good or good. Arthur Miller believes in the good and evil of Chura, he thinks that all characters are doing work of God, but actually shows encouraging devils. They are good and sincere Christians, but many people can not even follow the Ten Commandments. The Crucible of the theme of the Crucible Development Arthur Miller is a historical drama, but more important is the social and psychological drama. Various ways to develop themes through The Crucible are through characters, plots, settings, and conversations. According to Raymond Williams, the importance of witch trials, the moral crisis of society is clear and directly be formulated, have been described. In this way, life style overall quality of the organic non-existent You can see the qu ality (Ibsen to Brecht's play, until 1968). Abigail Williams of Arthur Miller 's Cru 埚 saw various aspects of the role of Abigail Williams in the whole drama of Krusselsburg. Arthur Miller created funny and complex characters with diverse and distinctive features, but in the first scene, the audience clearly recognized the characteristics of her control and operation. Abigail was first introduced as 17 years old, very beautiful girl, orphan ..., but since the parents were found to be absent, the audience became sad. Please refer to Mirror 's introduction to Abigail Williams with Waste. How realistic he is about her performance as a controller. In Arthur Miller's The Crucible, Abigail Williams appeared as an administrator of many key figures. Abigail can manipulate and control many characters well. Her beauty allowed her to influence others.

The decisions of a council in regulating operations within its Essay

The decisions of a council in regulating operations within its jurisdiction - Essay Example The researcher states that subject to the Food Vending (control) Act 2009, local councils are empowered to regulate trade within their geographical jurisdictions through licensing. The act provides that local councils, within their localities, can authorize trade in food substances through licensing and ensure regulation through revocation of licenses whose owners contravene requirements of the act. Subject to section 2 of the act, licenses can be revoked for misconduct or on grounds that the food supplies offered by the licensee are not safe for human consumption. The cases are based on the principle of delegated legislation and authority, and the scope of such legislations and authority. As a source of law, subsidiary bodies such as local councils and other government agencies are permitted to make laws and facilitate implementation of the laws. Similarly, authority may be delegated for implementation of primary legislation through formulation of policies. One of the basic principl es of such delegated legislations and authority is that they are limited to provisions of their parent acts that mandated them and any other superior source of law. A delegated legislation or authority can therefore not exercise more powers than is provided for by its authorizing legislation. In order to check on the concept of ultra ‘viresness’, the courts, when called upon, review implementation of delegated legislations to ensure that the agencies do not misuse authority to undermine rights and freedoms of their subjects.1 The scope of judicial review involves examination of the policy or decision in question to either approve, reverse or propose amendments to it. In exercising its review of delegated legislation, the courts look into a number of considerations. The first consideration is the conformity of the delegated legislation or authority to the powers as granted by the parent act. The aim of the courts would be to determine that the decision made in formulatio n or implementation

Korean Airline Porter's 5 Forces Coursework Example | Topics and Well Written Essays - 500 words

Korean Airline Porter's 5 Forces - Coursework Example The customers of KAL include passengers, corporate organizations as well as other actors in the aircraft industry among others. The table below highlights the industry analysis that constitutes Porter’s five forces that can impact on its operations. KAL has a total of 149 aircraft and is the largest in terms of consumers and it specializes in offering services in the following sectors: Passenger services, components and parts, aerospace services as well as cargo (KAI). However, there are other competitors in the aviation industry which include the following: Asiana Airlines which is the second largest airline in Korea, currently operating a total of 83 aircraft, on top of that, there are also five Low Cost Carriers (LCC): Jeju Air, Jin Air, Air Busan, Eastar Jet, and T’Way Air. Though KAL is the largest airline, the existence of rivalry among the other existing players cannot be ignored. It poses a threat to the airline. As noted above, there are six other competitors in the aircraft industry which entails that the threat of substitutes is high. For instance, â€Å"In 2013, 4.9 million international travelers, or 9.6% of all international travelers, used LCCs,† (KAI). The number of passengers using LCCs has dramatically increased which means that they can switch from KAL to these low cost planes. On the other hand, the consumers have the power to determine prices since they can easily switch to low cost careers and this in turn can force Korean Airlines to review its prices downwards. According to KAI, the bargaining power of suppliers is low as a result of the fact that â€Å"all U.S. aerospace exports are duty-free as of March 15, 2012, and as a result of the implementation of the Korea-U.S. FTA (KORUS).† This means that this trade agreement between the two countries is specifically meant to protect the interests of both nations. Prices are regulated at acceptable levels

Investigating Enzyme Activity :: Papers

Investigating Enzyme Activity PLANNING AIM === The aim of this experiment is to see how changing the concentration of Hydrogen Peroxide (H2O2) affects the rate of reaction of the enzyme Catalase. The reaction I am looking at is the breakdown of Hydrogen Peroxide into water and oxygen by the enzyme Catalase. The equation for this reaction is: 2H2O2 Ã   2H2O + O2 FACTORS ------- In this experiment I could change the following factors: Concentration of the Hydrogen Peroxide or Catalase, the time, the temperature and the Ph of the solutions. SCIENTIFIC KNOWLEDGE (See appendix 1) PREDICTION ---------- My prediction is that the higher the concentration of Hydrogen Peroxide, the greater the amount of oxygen given off will be within a period of time. The lower the concentration of Hydrogen Peroxide the amount of oxygen given off will be less than if it was at a higher concentration. I think this because there are more particles in a substance to collide and react at a higher concentration. VARIABLES I am not going to change anything other than the concentration of the Hydrogen Peroxide. The concentration of the Catalase enzyme, the temperature of the laboratory and the Ph of the solutions will remain constant. EQUIPMENT Hydrogen Peroxide (concentration - 0.5 1.0%, 1.5%, 2.0%, 2.5% and 3.0%) Safety Catalase Water trough, Burette, Stop clock, Delivery tube, Clamp stand, Conical flask, Syringe, Pipette Glasses/goggles, PROCEDURE 1. I will take the equipment drawn and set it up as shown. *(appendix 2) 2. I will fill the burette and water trough with water. 3. Using a measuring cylinder, I will put 10ml of Hydrogen Peroxide in the conical flask connected to the delivery tube. 4. Trying to prevent water from escaping, I shall turn the burette upside down and clamp it to the stand with the bottom of the burette in the water trough and feed the delivery tube through the burette.

Kite Runner Essay

In The Kite Runner, there are many examples of cruelty towards either the characters or their race as a whole. Two examples of cruelty include when the Afghanistan soldiers pick on Hassan, and one of them states that he has had sex with Hassans’ mother, and the other example is Amir setting up Hassan for stealing, in order to get rid of him. In the first example, the soldiers refer to Hassan as â€Å"You! The Hazara! † The lack of a noun here, i. e. Hassan’s name, demonstrates that Hazaras are treated as second class citizens, and aren’t deserving of being called by name. This has the effect of making Hassan appear to be an outcast, and it makes the reader feel sympathy for him, at being treated so harshly. The use of the sexually suggestive hand gesture by the soldier, when he’s making fun of Hassan because he had sex with his mother, again backs up the idea of Hazara’s being second class citizens. The metaphor â€Å"what a tight little sugary cunt she had† is used in a derogatory sense to further emphasise the contempt which Hazara’s had to endure back in 1970 Afghanistan. This achieves the effect of making the reader feel indignant at how Hassan is being treated, and that it is completely unjustified and is basically an advanced form of bullying. When the soldiers address Hassan, one of them says â€Å"Look at me when I’m talking to you! †. This is an imperative sentence, as the soldier is ordering Hassan to look at him, instead of requesting that he does so. The soldier is being demanding due to the fact that he believes his race is the superior race in comparison to the Hazaras, and that Hazaras always have to obey orders given to them, without question. In the second example of cruelty, Amir wonders to himself â€Å"how and when I’d become capable of causing this type of pain† As this is told via a first person perspective, it really helps the reader to understand what Amir is feeling, which emphasises the sense of cruelty, as the character who has committed the cruelty himself realises what he has done. Also, as he is speaking the past tense, with the use of the word â€Å"When†, it suggests that he wants to know what changed him to be so cruel. The use of the simple sentence â€Å"That was when I understood the depth of the pain I had caused†, is a great way of displaying the cruelty which Amir has shown in setting Hassan up for stealing his watch and money, and the sentence after it â€Å"not even Ali’s paralysed face could mask his sorrow† ,also helps to show this. These two simple sentences suggest that Amir realises that there is no justifying what he has done, that all he feels is relentless guilt, and that there is no other way of evaluating his decision. In conclusion, these two examples are strong demonstrations of the cruelty displayed in the Kite Runner, as they cover racism, which is shown in the first example, and in the second example, the words used e. g. â€Å" depth of the pain I had caused† clearly display Amir’s feelings of cruelty at what he himself has done.
