The affect of Caffeine on pulse rate Essay Example for Free

The affect of caffeine on whim dictate EssayStimulants are a class of drug that boosts, alternates and increases your faculty levels and they practise of the nervous system. Caffeine is in presents, such as Coca-Cola, tea and coffee, these are c eithered caffeinated drinks. Caffeine is not unremarkably recognised as a drug to near. Caffeine has an answer on your detectt rate, (this is how fact your hear beats) Caffeine is able to change the way your body and mind works Chocolate is known to oblige traces of caffeine in it alsoThe aim What is the point this try out-My aim in this experiment is to read what set up caffeine is prone to on the warmness rate, Also to compare someones punk rate who has consumed caffeine to someones who hasnt. This should give us a developed idea to the effects of caffeine. In this experiment there go forth be several versatiles-The independent variable-this is the variable I will be changing, this is the number of people of which are drinking the caffeine and the ones who are not. The Dependant variable-This is the variable we measure, Im measuring the persons heart rate, then working discover the difference to confront what effects caffeine is likely to boast on the heart rate. Controlled variables-The following variables I am memory the identical-Room temperatureThe volume of the drinkNo-one will consume caffeinated food or drinks beforehand.From what information I incur collected I predict that the pulse rate of the people drinking the caffeinated drinks will have an increased pulse, because as research plants, caffeine is a stimulant. Therefor the foresight of an increased heart rate when caffeine enters the blood stream seems good. I also think after a certain hitch of time, when the caffeine has left the persons system that the heart rate will lower again.Caffeinated Or Not?What will I do? How will I do it?Method- you will needSix cupsA bottle of a caffeinated drinkA bottle of a de-caffeinated dr inkHeart rate varan or a simple stop watchA fudge of results to evince your data move- What am I going to do?1) train 6 people to suck in sectionalisation in the experiment.2) Make each person sit down for 15 transactions in order to calm down their heart rate. 3) Pour the caffeinated drink into three cups of a 300 cm cubed volume. 4) Pour the de-caffeinated drink into another(prenominal) 3 cups of the same size. Making sure that the people participating in the experiment do not see which drink they are organism given( Blind testing) 5) Take each persons heart rate and record it in a table. This is the scratch byplay point 6) Give each person their drink, until now making sure you carry out a blind test. 7) Take each persons heart rate every 30 seconds continue to do this for a further 5 minutes. 8) by and by 5 minutes, take one final heart rate, this will help with your results. 9) Create a table of results to hold your information in, make sure the table is clear to re ad and easy to understand. 10) Work out the difference between everyones heart rateMethod 2- Shortened version-1) Prepare six people for the experiment by making each person sit down for 15 minutes to calm their heart rate. 2) Pour a caffeinated drink into 3 polyester cups of a 300cm cubed volume. 3) Do the same with the de-caffeinated drinks.4) Label the caffeinated drinks a and the de-caffeinated drinks b, so you wont mix them up, but dont let the participants know which label represents which drink. 5) Take each persons heart rate this is your starting point. 6) Give each person their drink, at random.7) Take each persons heart and record it in a table of results, do this every 30 seconds for a further 5 minutes. 8) With your results change in your table and work out the difference between the heart range, this should indicate the heart rates affected by caffeine.About my graph-The graph I used for this experiment is a line graph it shows various results of different pupils hea rt rate. The lines on the graph are all unique some have a sudden increase in heart rate whilst others have not. Pupil one- which is the pink line had a home rate of 72 this remained uninterrupted end-to-end the experiment, only rising and falling by a small few. However pupil 2 had a base rate of 78 but after drinking the drink at around 8-9 minutes the heart rate increased dramatically. Overall 3 results (pupils 1,3 and 5) practically remained the same, whilst the other three (pupils 2,4 and 6) had several increases whilst the drink being in their system. Summing up my results-We know from research that caffeine is a stimulant and stimulants affect the measure of your heart. So the three results that have a big increase in their heart rate, seem to show that they had caffeine in their system. However we did discover an anomaly, after 8 minutes pupil twos heart rate had a dramatic increase. This may well have been the caffeine but its more(prenominal) likely to have been caus ed by something called a placebo effect.This is when the pupil consuming the drink in the experiment got excited and this is what made the sudden increase in the pupils heart rate. After two minutes pupil fours heart rate increased also, however this time, the increase remained constant for a further two minutes before starting to drop again. This state a more obvious term of the effect of caffeine. The graph clearly shows which results are the ones effected by caffeine, and the ones which are not. Amendments- what I tidy sum I do better next time?In future experiments like this one, I think I would make sure that no-one involved in the experiment eats or drinks both caffeinated products before taking part in the experiment. This ensures us that their heart beat is at its normal pace. Because talk and movement can affect how our hearts beat I would also make sure that everyone in the experiment sits down for a lengthy period of time that was done before.This helps the heart lowe r to its base rate. Our results werent really valid because we were unable to control our controlled variable, this may be because the person who had consumed caffeine insisted on talking to everyone else, so this would have increased the other peoples heart rates also. In future experiments we can delay this by keeping people apart after taking part in the experiment, this way they cannot influence each others behaviour. Research has shown us that caffeine on average takes around 45 minutes to enter the blood stream, so we cannot be certain our results were callable to the effects of caffeine.This could be amended by measuring the pulse rate over a longer time span, so the caffeine had longer to affect our pulse. In the experiment I chose to measure my pulse over a period of two minutes, next time to show more valid and reliable results I would measure my heart rate over shorter intervals. Finally one more improvement would be to test more caffeinated drinks with our pulses, so th en we can rule out the thought off the results being due to glucose or so on, we then can be sure its definitely caffeine thats increasing out hear rate. Conclusion- what do I think?From this experiment I can conclude that caffeine can affect different people in different ways, depending on their diet, devolve on and size. Whether they are used to drinking caffeine constantly and how much their body can take of it. My prediction on average was correct as I suggested that the people with caffeine in their system were most likely to have a higher heart rate. This was mainly correct, but I was shocked to hazard out that my results were not valid due to the length of time caffeine takes to enter the blood stream.An voice of caffeine being used may be when an athlete drinks a caffeinated drink before they take part in their sporting event, the effect would be the increase in their pulse and more energy would be dispersed in the body. Personally I dont think this is fair, as I previous ly said caffeine effects different people in different ways, so caffeine could have a strong effect on certain people, whilst it has a less strong effect on others. This affects the balance of the game and its not natural energy being used in the event. This could be classed as cheating.

Thermodynamics Paper EssayThermodynamics is a branch of physics that studies the effects of changes in temperature, pressure, and volume on physical systems at the macroscopic collection plate by analyzing the collective motion of their particles using statistics. The term thermodynamics was coined by James Joule in 1858 to fate the science of congeners between heat and power.The starting point for most thermodynamic considerations ar the laws of thermodynamics, which shoot that energy can be exchanged between physical systems as heat or work. They as well as postulate the existence of a quantity named entrope, which can be defined for any system. In thermodynamics, at that place are four laws of very general validity, and as such they do not depend on the details of the interactions or the systems being studied. They are zeroth law of thermodynamics, stating that thermodynamic equilibrium is an equivalence relation first law of thermodynamics, about the conservation of en ergy second law of thermodynamics, about entropy one-third law of thermodynamics, about absolute zero temperature.An important concept in thermodynamics is the system. A system is the locality of the universe under study. A system is separated from the remainder of the universe by a demarcation line which may be imaginary or not, but which by convention delimits a finite volume. The potential exchanges of work, heat, or matter between the system and the surroundings take place across this boundary. There are five dominant classes of systems Isolated Systems, Adiabatic Systems, Diathermic Systems, Closed Systems, Open Systems.Thermodynamics describes how systems respond to changes in their surroundings. This can be applied to a wide variety of topics in science and engineering, such as engines, phase transitions, chemic reactions, transport phenomena, and even black holes. The results of thermodynamics are essential for other fields of physics and for chemistry, engineering, cell biota and material science.

Ideology of the films Essay Example for Free

Ideology of the selects EssayI. Introduction Feature packs such as Star Wars and The exterminator last just a couple of hours, but they concern months or even years to make. broad teams of people atomic number 18 involved in preparing for the action, and whence capturing it on camera. Then, when the acting has finished, more hard process begins on change forming the action into a fritter away fit for cinema and TV screens. This paper studies (1) who were the commencement charter-makers (2) know the development of cinema worldwide (3) be a state of ware of the different types of forward-looking depiction and (4) predict out the film-making at present. II. Background A. The origin film-makers The first off people to invent equipment for making films were the Americans W. K. L. Dickson and Thomas Edison, in the earlyish 1890s. Their apparatus consisted of a camera c wholeed the Kinetograph and a viewing box called the Kinetoscope. Only one mortal at a time could l ook into the viewing box to watch the film, which was in black and white, had no sound and lasted just a few seconds. Two French brothers called Auguste and Louis Lumiere first devised a way of project film images onto a large screen for an audience.The Lumiere brothers called their apparatus the Cinematographe. They carried out their first demonstration in a Paris cafe in December 1895. People were stunned to down the large, moving motion dates. Other inventors presently began creating new types of projectors and experimenting with making their own films. ? Early film-making estimates Film cameras do not record movement. The moving pictures we see on screen are actually still photographs, siren so quickly one afterward the other that they seem to merge. Each still photograph is called a frame.Most film cameras today take 24 frames every second, on a big distribute of film that is wound steadily through and through the camera. The first film cameras, though, could take only 16 frames every second. The length of the film on the reel was 20 or 25 metres, which gave just about one minute of screen time. So the first films usually showed just one, in short depiction. For example, LArroseur Arrose (A Trick on the Gardener) by the Lumiere brothers, made in 1895. The first film with more than one scene was probably Come Along Do , produced by the Robert capital of Minnesota company in Britain in 1898.The company nubed a scene outside an art picture gallery with a scene inside. A film-maker called George Melies began to produce multi-scene films, such as Cinderella (1899). Melies also experimented with interesting ways to join the scenes together. He often utilize equipment, such as slides and magic lanterns, to create special effects. At the turn of the century, two British film-makers working separately in B properlyon came up with creative ideas for shooting the scenes themselves. George Albert Smith invented a proficiency for enter a scene from diffe rent camera positions.In The Little Doctors (1901), a scene showing somebody feeding medicine to a kitten is shown first from a distance, then in close-up, then from a distance again. James Williamson had a different ideato shoot a penning of action across several scenes, instead of just one. In Stop Thief (1901), the lead purpose contributes out of one scene, then the film cuts to a new scene elsewhere and the lead face runs into the scene, continuing the story. An American film-maker called Edwin S. Porter used ideas like these especially effectively in a 1903 film called The Great Train Robbery. III. DiscussionA. The Development of Cinema Worldwide In the early days of film-making thither were no cinemas. Film-makers used specialist sales organizations to sell their films to entertainment organizers, who projected them as part of innovation shows in tent theatres. From 1905 to 1908 in the United States, thousands of theatres (known as nickelodeons) were set up especially for film. Permanent film theatres were also established across Europe, and film-making became a booming business. From 1908 a leading centre for American film-making substantial in an area of southern California called Hollywood.Established British and French film companies were joined by flourishing film industries all over the world. An Italian film company produced the first large-scale film in 1912. It was called Quo Vadis? , and used massive film sets and more than 5,000 actors. Film-going became so pop that from 1914 many lavish cinemas called picture castlings were created. They could seat thousands of people at a time. Film-companies began to make films that lasted for several reels instead of just one. Picture palace audiences had to wait in the middle of a film while the projectionist changed reels.Films in those days were silent, so picture palaces usually had a pianist or organist who played music to accompany the action. Film-makers also included short written sentences in the film to add to the story or explain what the actors were saying. One of the most historied silent film stars was the British actor Charlie Chaplin (1889-1977), who created the loveable character of the little tramp who had a diverting walk. Many film companies experimented with animated drawings and models, as well as human actors.European film companies introduced the idea of making information films about events in the news, as well as films for entertainment. ? Color and Sound From the early 1900s, inventors had worked on films with colour and sound. The first breakthrough with colour came in 1908 in London, when G. A. Smith demonstrated a colour film process called Kinemacolour. However, Kinemacolour shades were based on just two color, so films go along to be made in black and white. The first colour films to be created successfully from two colours were Toll of the Sea and The Black Pirate, shown to the public in 1922.In 1926 the American film company Warner Brothers lucky audiences with a series of short films that had sound to match the pictures. As the sound was recorded on a separate disc, the words did not always match the mouth movements of the actors. Warner Brothers The Jazz Singer was the first full-length talkie, in 1927. The film company Fox soon developed a more effective technique for recording the sound onto the film itself. During the 1930s, Hollywood film companies made the most of the new sound engineering science by making musicals with singing and dancing stars such as Shirley Temple, and Fred Astaire and Ginger Rogers.Gangster talkies and romantic comedies were popular in the United States and Britain, although at this time the Japanese film industry was the largest producer of films in the world. In 1934, the Bombay Talkies studio was formed in India, founding one of the biggest film industries in the world. While film companies had been picky creating talkies, they had also been working on perfecting colour in films. F inally a process was developed that used three colors to create different shades, rather than just two. In 1935, the first three-strip Technicolor film was produced, Becky Sharp.From then on, moving pictures not only sounded real, they looked real too. B. Different Types of Modern Films Since the early days, many different types, or genres, of feature film have been made. These include westerns (such as The Magnificent Seven), thrillers (The Fugitive), comedies (Home Alone), action adventures (Indiana Jones), supernatural horror (Dracula), war epics (The Great Escape), romantic comedies (When Harry Met Sally).Crime and gangster films (The Godfather), films with animation (Who Framed Roger Rabbit? ), spy adventures (Mission Impossible), kung-fu extravaganzas (Enter the Dragon), science-fiction (E.T. The Extraterrestrial) and modern musicals (Grease and Moulin Rouge). Sometimes films combine two or more genres.Some films are produced with three-dimensional technology, so that if you put up special glasses, the images on-screen appear to have more depth, just like in real life. Other films are made for IMAX cinemas. These special cinemas have giant-sized screens with sophisticated sound systems to make you feel as if you are right in the middle of the action. IV. Conclusion A. Film-making today Film-making requires different specialist staff and technical processes, depending on what the film is about.All films go through three broad stages before they are ready for an audience. During the pre-production stage all the preparations are made for filming. The producer chooses the story, raises money and employs the people who will work on the film. The scriptwriter writes the words, creating an exciting dapple and interesting characters. The director decides on the overall style of the film and chooses the leading actors. The art director is in charge of designers for the film sets, costumes and makeup, and choosing locations outside the studio.Technical directors are in charge of crews who build huge film sets and arrange lighting, sound and special effects. The production manager controls the budget and makes practical arrangements for filming. During the production stage filming takes place. Stories are not usually filmed in the right order. The actors and crew film all the scenes that take place in one location before moving on to another. The director guides the creative elements of the film, from self-aggrandising opinions on the story, to instructing the actors, to choosing camera angles. The director is helped by people in different departments.For instance, a continuity soulfulness makes sure that all the details are correct in scenes that are shot out of order (such as the actors clothes and length of their hair). That way, when the filmed scenes are put into the right order later, they will run together smoothly. The post-production stage happens when all the action has been filmed. An editor cuts sequences of action and joins them together, adding the sound. When the director and producer are happy with it, the finished film is then ready for distribution companies to sell to cinemas or TV companies.

Fiction literature EssayHemingways modernist movement of compositiontelling requires an impersonal narrator. The narrator describes the scene, and interjects small actions into the dialogue, entirely remains a facilitator for the subscriber to concentrate on the dialogue and the action of the report card. The narrator in this story seems to tell the story as if it were a video clip, a nameless railway station someplace between Barcelona and Madrid, ghostly white hills, a faceless waitress and an anonymous couple.The use of this narrator makes the reader look much deeper into the dialogue of the couple, because without the narrator spelling out the action for the reader, one is forced to watch much more from the characters words. This modernist device tends to separate the reader momentarily from the text, so that the full impact of the story is not truly felt until one is finished reading. However, this device serves to make the story connect on a deeper level, and to ha ve more impact as it hits one suddenly, instead of being built into a slow climax.From almost the beginning of his writing c atomic number 18er, Hemingway employed a distinctive style which drew chin wagging from many critics. Hemingway does not give way to lengthy geographical and psychological description. His style has been said to wish substance because he avoids direct statements and descriptions of emotion. Basically his style is simple, direct and somewhat plain. He developed a forceful prose style characterized by simple sentences and few adverbs or adjectives.He wrote concise, vivid dialogue and require description of places and things. Critic Harry Levin pointed out the weakness of syntax and diction in Hemingways writing, but was wide awake to praise his ability to convey action The majority of his early novels were narrated in the first person and enwrap within a single point of view, however, when Hemingway wrote For Whom the Bell Tolls, he used several different report techniques.He employed the use of internal monologues (where the reader is in the mind of a particular character), object glass descriptions, rapid shifts of point of view, and in general a looser structure than in his earlier works. Hemingway believed that a writers style should be direct and personal, his imagery rich and earthy, and his words simple and vigorous. The greatest writers have the gift of brevity, are hard workers, diligent scholars and competent stylistsTo explain Hemingways style in a few paragraphs in such a manner as to satisfy those who have read his articles and books is almost impossible. It is a simple style, dead on target forward and modest. Hemingways prose is unadorned as a result of his abstaining from using adjectives as much as possible. He relates a story in the form of straight journalism, but because he is a master of transmission system emotion with out embelli

What is the marketing mix

What is the marting liquefyWhat is the marketing unifyThe merchandise mix of Product, damage, Promotion, and Place was introduced to market education by McCarthy (Yudelson 1999). First formu modernd as a pedagogic tool, the innovation of the 4Ps represents a comprehensive way to describe the main tasks of marketing managers. (G obsolescentsmith 1999). It is utilised to implement corporate mean after having researched and audited the marketing environment, i dentify and chthonicstood the client, established a strategy and decided which market(s) or market segments to serve, or want to serve (Anonymous 2006).The Marketing in in alloy has its origins in the 60s Neil Borden (1964) identify twelve controllable marketing make dos that would result to a profitable business operation. Jerome McCarthy (1064) reduced Bordens factors to a simple four-element mannequin Product, Price, Promotion and Place. Practitioners and academics embraced the Mix figure of speech that co ncisely became the established and essential element of marketing theory and operational marketing solicitude. (Constantinides 2006) The 4Ps were a suitable framework for the 1960s environment which was characterised by profit making consumer manufacturing companies who were concerned with reaching their clients in an age of emerging mass media and national mass markets. (Anonymous 2006) Eventually the 4Ps of the marketing mix became an reliable paradigm in academic research, the validity of which was taken for granted. (Grnroos 1994). There are voices though from academics and researchers which shout that the Marketing Mix in the form of the 4Ps is not able to feeling the latest marketing challenges.The components of the MixProductSince its the consumers learning that should be the centre of proceeds polity, the intersection should not be defined as just the sit of its own physical properties. The perceptions are influenced by different parameters, much(prenominal) as any a ssociated services, the image, the brand telephone, take down the social and cultural connections, or the perception of its own differentiation from competition. A harvest is a concoction of tangible and intangible attri savees, including functional, social and psychological utilities or turn a profits (Anonymous 2006).PricePrice is the only revenue generating element of the marketing mix the other elements consume resources. There are common chord basic pricing strategies that all organisations can pursue for existing products pricing above the market (higher than similar competitve products), pricing below the market (lower than competition) and pricing at the market (almost at the price of competition) (Anonymous 2006).PromotionOne long-term purpose of progression is to influence and encourage buyers to accept or adopt goods, services and ideas. Potential buyers go with and through a psychological or behavioural process before purchasing a product. AIDA, which is an acron ym for Attention, Interest, Desire and Action bes psychological processes attention is a cognitive process, interest and desire are affective processes and action is a take the stand behaviour process (Anonymous 2006).PlacePlace, or distribution strategy concerns the routes by which marketers of products and services can catch that these reach their intended market. We normally refer to these routes as marketing channels, which include those intermediaries that products and services pass through from the point of production to the point of final use (Anonymous 2006).CriticismTQM and Relationships anxiety Adaptation, not RevolutionYudelson (1999) identified six major marketing developments that challenged the 4Ps since the introduction of the Marketing Mix.Focus on the customer via the Marketing thought (1960s)Broadening of marketing to include not-for-profits, services, causes, and even politics (1970s)Identification of the exchange transaction as the core out of marketing (19 70s)Introduction of Total Quality Management with its emphasis on customer satisfaction (1980s) reference from transaction marketing to relationship marketing (1990s)Identification of the firm as a member of a complete assess chain (1990s).Since the 80s, the definition of Product as anything offered is challenged due to the invigorated perspective that organisations face The success depends on the ability to transform satisfaction to delight. Customer satisfaction is identified as the untested driving force, and that is one of the foundational ideas of TQM. Place is expanded to include the entire distribution system, which creates time and place return and whitethorn incorporate specific systems such as just-in-time delivery as place of channel management.During the 1990s, another(prenominal) significant interchange occurred. The share of relationships in the marketing activities of the organisation replaced the transaction perspective of earlier times. Price is no long-run the amount of money paid to acquire a single Product but the lifetime costs associated with the acquisition, use, and ultimately disposal of the benefits attained during a period of time. Place is no longer just the point of exchange since that fails to communicate the interactions that occur as the product changes ownership and utility from ideaualisation to final disposal.Yudelson suggests that after nearly 40 years, the 4Ps need to let go because, as shown, the terminology has not managed to handle the challenges of developments in marketing thought and practice. However, no familiarly agreed or satisfactory electrical switch has appeared and anyone who grew up on the impression of marketing mix (customers, marketing professionals and academics) would face significant dissonance if the tombstone paradigm were dismissed. So, he suggests that the best strategy is Adaptation and not Revolution. His proposed adaptation focuses on the essential aspects of marketing as exchange d riven behaviour, maintains the simplicity and familiarity of the 4Ps, recognises the concerns of past critics, and is capable of applying to both single instance proceeding and long-term strategic relationships.Product should be redefined as all the benefits (present or anticipated) that the buyer or acquirer obtains from the exchange. It is recommended that Product be renamed as capital punishment to communicate the sense of benefit to the customer.Price should be redefined as everything that the acquirer gives up to obtain the benefits. It is suggested that we refer to the import P as Penalty to signify those things that the customer would induct to give up or seek to minimize while obtaining the benefit or Performance associated with the exchange.Promotion should be redefined to include all of the information that is communicated between the parties to the transaction in keeping with the flowing thought on combine Marketing Communications. The purpose of the communication o r information is to influence or encourage each party to enter into the transaction/ relationship. This is accomplished by providing information regarding the costs and benefits of the transaction-or better-the comprehension of the Performance and Penalty.Place can be now defined as all that is done and indispensable to facilitate or bring about the exchange and therefore, Yudelson proposes its redefinition as Process.Relationships Marketing A paradigm shiftGrnroos (1994) believes that a paradigm shift is taking place in marketing. One of the main reasons lies beneath the nature of marketing mix. The marketing mix is a list of categories of marketing variables. A list never includes all rele vanguardt elements, it does not fit every situation, and it becomes obsolete. Moreover, the 4Ps represent an oversimplification of Bordens original concept, which was a list of 12 elements not intended to be a definition at all. This list would most probably bugger off to be reconsidered in any given situation. Grnroos believes that McCarthy either misunderstood the meaning of Bordens marketing mix or his followers misunderstood McCarthys intentions. Probably Bordens original idea of a list of a large flesh of marketing mix ingredients that have to be reconsidered in every given situation was shortened for pedagogical reasons and a to a greater extent limited issue of marketing variables seemed to fit typical situations observed in the late 1950s and in the 1960s. The 4Ps were never applicable to all markets and to all types of marketing situations.The development of alternative marketing theories (interaction/ne cardinalrk approach to industrial marketing and the marketing of services, customer relationship economics) demonstrates that even from a management perspective, the marketing mix and its 4Ps became a problem. Gronroos concludes that in industrial marketing, services marketing, managing distribution channels and even consumer incase goods marketing itself, a shift is clearly taking place from marketing to anonymous masses of customer to developing and managing relationships with more(prenominal) or less well-known or at least somehow identified customers.Other Reviews and CriticismConstantinides (2006) undertook a literature review on the status of Marketing Mix at the 21st century. He discovered that many researchers stockpile serious doubts as to the role of the Mix as marketing management tool in its original form, proposing alternative approaches adding new parameters to the original Mix (e.g. 7Ps for services) or replacing it with alternative frameworks altogether. Some of the weaknesses of the 4Ps identified in the study are domain specific ignoring the forgiving factor, lack of strategic dimensions, offensive posture and lack of interactivity. Two limitations however seem to be common in all reviewed categoriesThe patterns internal orientation The lack of explicit market input in the framework which sources from the fact t hat the Mix was originally developed as a concept suitable for marketing of consumer products in the mass-oriented US manufacturing sector of the 60sThe lack of personalisation Significant shifts of consumer behaviour such as individualisation, diminishing brand preference, value orientation, increasing sophistication etc. have undermined the effectiveness of the impersonal one-way communication and the mass marketing approaches.Hyman (2004) undertook a similar study on the criticism of the Mix. According to that, some marketers contend that the scope of the 4Ps is substandard from a pedagogical or applied perspective. To address this limitation, they updated the schema by refining the current Ps, adding new Ps, broadening its perspective, or adapting it to specific industries. Moreover, he summarised previously published criticism of the 4PsInadequate theoretical fundament nary(prenominal) formally integrated into the exchange paradigmFails three of the five requirements for a so und salmagundi schemaOverly focused on consumer goods, yet is production quite a than marketing-concept orientedCannot account for the integral range of marketing management activitiesIgnores strategic marketingFocuses only on the acquisition stage of economic consumptionContains an increasingly catch-all (i.e. atheoretically focused) promotion categoryFails to account for interactions between Ps or boundary-spanning topicsIs incompatible with the relationship-marketing paradigmvan Waterschoot and Van den Bulte (1992) in their own research identified five key limitations of the 4Ps modelIt focuses on what marketers do to customers rather than for them.It is externally directed and ignores the internal market.It says nothing about interactions between the mix variables.It takes a mechanistic view about markets.It assumes a transactional exchange rather than a relationship.The Xbox 360 Marketing MixThe Xbox 360 is the second icon game locker produced by Microsoft, and was develo ped in cooperation with IBM, ATI, and SiS. The Xbox 360 is the successor to the Xbox, and competes with Sonys PlayStation 3 and Nintendos Wii as part of the seventh generation of period of play systems (usually called next-gen) (Wikipedia 2007).ProductName and ConceptThe term 360 represents a circle and is inline with the concept of the product. The customer is placed at The centre of the scram. Its a videogame and an entertainment system that integrates music, picture, games and icons. Everything revolves around the customer.(Porcaro 2005)ClassificationXbox 360 belongs to the shop consumer products category, which includes products purchased after the consumer shops around to find the best deal based on comparisons of price, quality, style, durability and other product attributes that are felt to be important. Although due to shortage at its launch many consumers were making campaign to find one and others were forced to buy from eBay at inflated prices, 3 months after the laun ch the console could be purchased with smaller effort. Therefore, a classification of Speciality is not justified.Product MixThe total erect of products a company sells is called its product mix, which consists of its component product lines. The product mix of Microsoft regarding console gaming consists of the side by side(p) product lines Xbox 360 consoles, the Xbox Live Services (Marketplace, Video and Arcade), console accessories and Microsoft Games.Xbox 360 Product LineDuring launch only two configurations were for sale the Core and the Premium editions. Over time, the product line length rose to 3, in an Up-Market corrupt move from Microsoft, by introducing a high end version (Elite).Product PositioningMicrosoft suckers both periodic and hard-core gamers. The Core and Arcade versions seem attractive to the former, while Premium and Elite are more appropriate to the latter.Product LevelsThe five levels of customer value hierarchy are as follows (Kotler and Keller 2006)Cor e benefit The benefit that the customer is really buying. The buyer of the Xox 360 is buying video gaming.Basic Product The Xbox 360 includes a video games console and a controller.Expected product A set of attributes and conditions the buyers normally expect. Gamers expect from the seventh generation of gaming systems good graphics and sound performance, a wireless controller, digital connection with the HD TV and the amplifier, online gaming with friends through the internet and the ability to listen to music and watch videos.Augmented product The level in which the product exceeds customer expectations. The Xbox 360 through its Xbox LIVE service lets the customers download purchased or promotional material. This includes game demos, movie and game trailers, Arcade games as well as add-on game content (items, costumes, levels, maps etc).Potential product All the possible augmentations and transformations the product might undergo in the in store(predicate). Even before the launch of Xbox 360, Microsoft was researching slipway to create a video store accessible through the console, as well as a TV service which would add IPTV functionality. One year after the launch of the console, the Xbox Video Marketplace was introduced in the United States, and the Microsoft TV service under development.PricingThe following table summarises competition pricing during their various(prenominal) launch.Note that Playstation and Wii launched at November 2006, almost a year subsequently than Xbox.The Xbox 360 was the first next-gen console to enter the market. Generally, if the product is an innovation, then the initial price is usually set quite high (Anonymous 2006), but this is not the policy that Microsoft followed. Microsoft used the strategy of Price penetration, in an effort to take as much market share as possible. In fact, it was reported that Microsoft was losing $126 per unit sold (Joystiq 2005). Robbie Bach, president of Entertainment and Devices Division, said that the Xbox 360 business pull up stakes become profitable in 2008 and that the profit to make is not on the hardware itself, but rather on Live service subscriptions, accessories and games (Gamedaily 2007).In August 2007, Microsoft dropped the prices by 20 50. In October 2007, they introduced the Arcade version and priced it exactly the same as the Wii, that is At the market.Odd-even pricing assumes product sales benefit from prices such as 99.99 rather than 100.00, because customers will think the product is a good deal (Anonymous 2006). As we saw, Microsoft followed this policy, as all next-gen competitors did.PromotionMicrosoft utilized the following Marketing Communications Mix for the launch of the console system.AdvertisingThe advertising campaign took place via television, magazines and internet sites. The tag line was Jump In, which was in complete accordance with the name and the concept of the product (the center of the experience). The ads were introducing the ide a that its more fun to play when youre part of a community, that games have always been more fun when you play with friends (Porcaro 2005).Sales PromotionThe sales promotion took place through online contests and websites. OurColony.net offered challenges to its community, rewarding solutions with cropped pictures of the console and game screenshots. OrigenXbox360.com was offering visitors an opportunity to enter in various contests for a take chances to attend promotional pre-launch events. Hex168.com hosted a number of images that appeared to perpetuate obscure conspiracy theories, but sometimes contained catercorner references to Xbox 360. The campaign was later revealed to be a U.S. contest that offered participants a chance to win one of three hundred and sixty Xbox 360 console bundles six eld before the official launch (Wikipedia 2007).Marketing frequent RelationsIn order to assist the launch and to increase awareness, Microsoft made use of Marketing semipublic Relations. The official unveiling of the Xbox 360 occurred on May 2005 on MTV in a program called MTV Presents The Next generation Xbox Revealed (Wikipedia 2007). Elijah Wood hosted the show which featured a musical performance by the band The Killers. Ten days later the Xbox 360 was featured on the cover of TIME Magazine along with an associated article. Obviously, the viewers of MTV belong to the target market, while the cover of TIME magazine was a huge boost to the hype.EventsMicrosoft is one of the major exhibitors in the annual E3 Media and Business Summit which is considered as the biggest annual event in the video game industry. The announcements regarding future development are taking place at the Microsoft keynote event, which is highly anticipated by the planetary video game media and community.Microsoft is also a frequent sponsor to gaming events. In association with adidas and EA Sports, they sponsored the Xbox adult male Cup, which received a lot of publicity by the gaming com munity. Gamers who qualified through national anterior rounds were given an all-expenses paid trip to Berlin to take part in the competition representing their nations in matches that took place in an 8,500 seat stadium. Microsoft managed to identify with the target market as well as increase awareness and express commitment to the community.Place (Distribution)As mentioned earlier, the product suffered from shortages during its launch, due to huge demand and slow production. However, three months later the problems had been bypassed and it is worth noted that in its first year on the market, the system launched in 36 countries, more countries than any console has launched in a single year.Microsoft chose to distribute the products through the Producer Wholesaler retailer Consumer channel. For the countries where Microsoft has physical presence, the Wholesaler intermediary part was played by the regional division. The Xbox 360 is distributed intensively, which means that all ava ilable outlets are used for distributing it.ConclusionThe marketing mix of Product, Price, Promotion, and Place was introduced to marketing education during the 1960s. Practitioners and academics embraced the paradigm that soon became the established element of marketing theory and operational marketing management. Eventually the 4Ps of the marketing mix became an unquestionable paradigm in academic research, the validity of which was taken for granted. However, many researchers and academics object. Yudelson believes that the Mix requires adaptation to the challenges of the era (TQM and the role of relationships) and proposes redefinition of the components. Grnroos argues the 4Ps was never intended to become a paradigm and started as a simple list which was an oversimplification of a larger list. He states that the 4Ps were never applicable to all markets and to all types of marketing situations, and that we have started to experience a paradigm shift towards relationships marketin g. Other studies also conclude that the marketing mix of the 4Ps is getting old and cannot address complex environment issues, such as management of personalisation.The application of the marketing mix model to the Xbox 360 gaming console system revealed that model managed to incorporate some of the major marketing planning activities of Microsoft under its 4Ps components. However, Yudelsons model seems to apply better. Xbox 360 is not just about the actual console product, but through its consolidation with other products and services its about the Performance of the entertainment experience. Its Promotion is inline with the current thought on Integrated Marketing Communications. And finally, its Place (distribution) is more about the Process of distribution, from which Microsoft actually suffered during the launch. Also, the marketing mix model failed to incorporate the personalisation component of the product. That is, through the LIVE services each user is uniquely identified. Microsoft has access to personal information, such as favourite games, music and movies and is able to propose similar content to the customers upon request. Unfortunately, the 4Ps did not manage to secure this aspect of Xbox 360 marketing.We conclude that the marketing mix is a tool which has performed well in the past and may still do in many cases. However, the increasingly complex environment demands adaptation and expansion. Personalisation for example is a very important component and should be incorporated under the umbrella of the new XPs, whatever number the academia decides that X should be.ReferencesAnonymous (2006).

The Adventure of the German Student

The fortuity of the German StudentThere ar multiple ways to analyze a literary wrick, with the basis of the critical approaches. The reader apprise select any of them in secern to analyze his or her piece of work. Particularly in fellowship to analyze this chronicle I am going to single-valued function the Psychological approach.Washington Irvings story, The Adventure Of The German Student, was the one that attracted me the most, because of its enrichment content round the functioning of humans brain, and as swell up as, active the reinforced form that an unpleasant environment has in peoples inter someoneal relationships, and how this positioning stinkpot produce a serious damage in anyones mental health.The Adventure Of The German Student shows us how union and neighborly movements can interfere in peoples normal behavior and personality. As we atomic number 18 by record a social universe, we can non avoid interactions with others, as well as we cannot avoid b eing influenced by social accompaniments.Irvings story tries to focus our attention on a beardown(prenominal) socio- governmental and even religious event which occurred in France between the years (1789-1799) that it is well known as The french Revolution, besides he does not leave behind the reaction of the storys psyche character Gottfried Wolfgang who was surprised and ready to release a little more ab show up this new city and that revolution that was on its height. Throughout the storys development it beats evident Wolfgangs un authorable behavior which was accompanied by a betting rural area of idea that was increasing at the time the story was developing, finding himself in an awful situation at the end of the story which leads him to spend his life in a madhouse.This story begins giving us a brief orientation about which is going to be the plot in where the story get out be developed. This first paragraph fountains us outstanding information that go out lead us to f totally apart understand the story and to be more familiarized with the events that allow be involved on it. At the end of this first paragraph the teller stops the narration, and in that respect is an intervention of the storys author who considers important to reveal the type of life that the tip character of the story Gottfried Wolfgang had before going to Paris, by saying - only when I should first tell you some topic about this teenaged German.Gottfried Wolfgang is presented as a young German man of good family also as a visionary and enthusiastic character these qualities are earthy in young people, especially in those who are studying and throughout the acquisition of knowledge they also acquire new ways to perceive the gentleman.Studies are productive, merely is there any possibility to execute nuts after studying so hard? The answer might be relative, but it is important to say that the capacity of humans brain is endless, and that there is a discipline pi ssd Psychology which its principal role is to analyze human behavior, as well as, motivation, personality and interpersonal relationships.We train to consider that Germanys education system was and still is considered admirable for its strict and organized strategies toward teaching, and because of this, students should have an intense dedication, if they truly indispensableness to succeed.But sometimes that intense dedication to something can produce mental break downs. Now days, the condition mental breakdowns is not commonly used by experts in this area, in fact, they see this term as a popular term invent by society, but no matter what the real name is, mental breakdowns are considered mental illnesses, that can lead people to a complete mental disorder, if it is not treated properly. We know that under luxuriant pressure, continued everywhere a long period of time, anyone can be overwhelmed, and bend. All of us have a breaking come out (Dr. William C. Menninger, 1959 U.S .A) As it is shown in the moment paragraph of the story His secluded life, his intense application, and the singular nature of his studies, had an effect on both mind and body. A secluded life is not good for anybody people should have time for everything, especially to know being with others and to share. Eventually, a person who since a young age, kindred Wolfgang, is situated away from people this will cause different psychological damages, and if we are not okay mentally is reasonable that our body cannot work in a good way. People who are isolated perceive and make their own deductions of the world approximately them. In the same second paragraph, Wolfgang is compared with Emanuel Swedenborg, like Swedenborg, he had an ideal world of his own around him. Swedenborg was a Swedish inventor and scientist who lived between the years (1688-1772).Swedenborg entered into a spiritual phase in which he experienced dreams and visions. This culminated in a spiritual awakening, where he claimed he was ap portended by the Lord to hold open a heavenly doctrine to reform Christianity. He claimed that the Lord had opened his eyes, so that from then on he could freely visit heaven and hell, and tittle-tattle with angels, demons, and other spirits.Taking into account the comparison do between Wolfgang and Swedenborg, I can assume that by chance Wolfgang was inspired by Swedenborgs literature, and that, if we investigate about this literature we can see that, most of the things that Swedenborg wrote had a strong influence in Wolfgangs behavior, at the point that we can find similarities between them. Wolfgang thought that there was an evil influence hanging over him an evil genius or spirit seeking to ensnare him and ensure his perdition. I am only sure that, when a person reads something, any literary text, in some way this person is influenced by the text, and psychologically if this person finds something that can be productive or beneficial something that he or she likes, it will be introduced and used by his mind, consciously or not.The truth is that our characters mind started to get weaker rapidly, at the point that Wolfgangs friends started to worry about him His friends discovered the mental malady preying upon him, and determined that the best cure was a change of scene. It was evident that Wolfgangs friends started noticing his disordered condition, maybe because he was acting differently at the point that his friends could not feel comfortable with him anymore.he was sent, therefore, to finish his studies amidst the splendors and gayeties of Paris. Thinking that the principal problem was the environment in where he was, he was sent to Paris in order to finish his studies, erect imagine, to send a young male child to explore a new city by himself without any friends or family. peradventure for him it was a kind of adventure and from what he had heard about that city, it was going to be a gripping trip for him. Wolfgang arrived at Paris at the breaking out of the revolutionThe French Revolution (1789-1799) was a period of political and social upheaval in the history of France, during which the French governmental structure, previously an peremptory monarchy with feudal privileges for the aristocracy and Catholic clergy, underwent radical change to forms based on Enlightenment principles of nationalism, citizenship, and inalienable rights. The French Revolution was a time of complete chaos in Paris. Popular, as well as, military confrontations and decapitations where the principal events of the day. Wolfgangs expectations about that new and fascinating city were different from reality. Despite, his enthusiasm was strong enough to become amazed with those radical socio-political changes. But then, his perception of those events, started to change, now he was another citizen who disliked those political movements and was against assassinations. He felt in some way trapped and the only way he had to escape of those fearful scenes was through reading.He is described as a literary ghoul. A ghoul by office represents something disgusting that shows morbid interests in things. This description tells us that his mental faculties were in manner unhealthy, as well as his behavior. He was trying to find a safe place between all the shocking things occurring on the street. He shut himself up physical and mentally. Although, he is described as a boy of ardent temperament, was imagination his reigning ability. Imagination works with the unconscious mind, and leaves aside consciousness and reality, in order to help the person to entertain himself of an unwanted situation.In the Psychoanalytic world, was Sigmund Freud the one who first explained and developed this theory. Freud postulated that there were a number of defense mechanisms-including repression, reaction-formation, regression, displacement, and rationalization-that protect the conscious mind from those aspects of reality it may find rugged to accept. In Wolfgangs case, was throughout imagination, where he found a way to repress all the events that were possibility around him, in order to be in some way calm and focused in something else. he was a passionate admirer of pistillate beauty, is common that a boy of his age starts admiring female beauty, but results difficult to understand, how he might think about something beautiful in middle of such horrifying events?, maybe he needed a straddle or just somebody to talk with. I do not know for sure, but it was evident that Wolfgang started to recidivate his mind little by little. a dream produced an extraordinary effect upon him. It was of a female face of transcendent beauty. So strong was the impression made, that he dreamt of it again and again.We do not know drively what Wolfgangs age really was, but considering the description made by the narrator at the beginning of the story, he was a young man. Is solely natural for young man to be delighted by a g irl, maybe for him it was about time to experience to be with a girl, but just because of the kind of life he had and all the things that were occurrence around him, he could not experienced that at the moment.Dreams are an insight into our emotional preoccupations .This is just one of lots of definitions about what dreams really are. Experts in the psychiatric area and others still cannot find an exact definition for dreams, and this is because the complexity of understanding humans brain has not been reached yet, despite all the scientific advances.The way in which Wolfgangs dreamed with this female face again and again, shows his desperation for having a couple and maybe for calming down his sexual appetite, in a manner he was obsessed by her or maybe he was sexually obsessed. Obsessives disorders involves obsessions-unwanted thoughts or images that are unsettling or interfere with an individuals life, followed by compulsions-actions that temporarily relieve the anxiety caused b y the obsessions . The unwanted thoughts and images that Wolfgang was having, shows through different psychological studies, that he had an obsessive disorder. maybe that disorder started some time ago, before travelled to Paris and maybe it could occurred in his childhood, we are not sure, but what it is sure is that this disorder increased since he started to live and experience all the atrocities that took place during the French Revolution.Our sexual function is an important component and indicator of overall health and well-being sexual problems or dysfunction may result from, or even cause, physical or mental illness or deterioration in important social relationships. .According to Dr. Sadie Sheafe sexual problems can cause mental illnesses, maybe this is what was happening with our character, just imaging, being surrounded with all those majestic scenes of death, with nobody to talk with, and if that was not enough being in some way trapped physically and mentally. It was e vident that he was starting to lose his mental qualities. At the time you experience a dream, is your unconscious mind the one which works the most, for this reason Wolfgang could not do anything about those dreams that he was having, in fact they were consuming his life and taking pigheadedness of him, by the time that he was passionately enamored of this shadow of a dream, can you imagine yourself being in love of a dream?. Results difficult to think about that, but that was Wolfgangs situation, and when the narrator says it became one of those fixed ideas which haunt the minds of melancholy men, and are at times mistaken for madness. Here, the narrator describes Wolfgangs personality as a melancholy man, which means that he was sad, and maybe sank into a prolonged falling off that was destroying his mental health.One night when Wolfgang was pass through Place de Grave which was the square in where executions were performed, he shrank masking with horror at finding himself clo se by the guillotine A guillotine was a auto used to cut peoples head off, and was used by the times of the French revolution, that was the political movement our character was experiencing. For a person that does not know what a guillotine is, and it is not sensible about what was happening in that city, is not going to shrank back with horror, that is for sure, but as Wolfgang did know what was happening there and the purpose of that scary instrument, he felt in that way, and his first reaction was to feel fright and step aside. Obviously his nerves impulses were extremely sensitive. Wolfgangs heart sickened within him, and he was turning shuddering from the horrible engine he was shudder horrified by this monstrous instrument, here is evident the level of nervousness that he had and how tormented he was by all the horrible things that were happening there, the involuntary action of shaking is common in nervous people.At the same square he found a charr seating on the scaffol d, He approached, and addressed her in the accents of sympathy even though he was passing through a bad situation, he neer lost his well mannered behavior, remember that he was a man of good family, so he knew how to be a gentleman and how to speak with a lady. His surprise was that this woman was the same that have been haunting his dreams he was amazed and a little telephone number confused. the very face which had haunted him in his dreams.Trembling with violent and conflicting emotions here is shown again that Wolfgang was a nervous and insecure person. the student, for the first time, blushed at the scantiness and indifference of his dwelling. When a person blushes, shows that he is tinge embarrassed about something, in this case Wolfgang felt ashamed of his shelter, because he was worried about what his female companion might think or say about it. He was fascinating by her beauty, but still he thought of abandoning his chamber to her, and seeking shelter for himself elsewh ere, although, his attraction to her was infinite, he knew what was the right thing to do in that case, he was an educated young man and he felt right to give her his dwelling, and find a new place to live. But her beautifulness and the attraction that he felt about her was strong enough to prevent such thing.She is described as an enthusiast like Wolfgang She was evidently an enthusiast like himself, so maybe we can speculate that she had approximately Wolfgangs age. No matter the age, any person can be an enthusiast, but this quality is more observable in young people.our hearts are united in the eye of reason and honor we are as one. Wolfgang did not believe in the liberal theories of the day, but rather, he had his own theory and even his own way to see marriage. We have to considerate that during the French Revolution, was established a new constitution, where the assembly whished that Catholicism should cease to be the righteousness of the State and that liberty of worship sh ould be established. The Catholic Church was confiscated by the state. It was a complete religious chaos, mean while people were fighting for their religious rights. So, imaging what could a young couple do amid all that disorderliness. For Wolfgang, the thing that he was doing was reasonable and honorable, maybe in some way he was criticizing the unreasoned strategies that the state was taking against religious institutions.At the end of the story the mind of our principal character returns to reality, when he finds out that his beautiful bride was dead, and that she was already dead from the first beginning. Horrified and frantic, he alarmed the house. A scene of confusion ensued. The student fell into an uncontrolled behavior, which started to get violent The student burst into a frenzy. The monster the fiend has gained possession of me and again he remarks the presence of an evil spirit that was possessing him, that might be the devil. The story never shows us the physical pre sence of the devil or some other evil figure. All those thoughts were just in Wolfgangs mind. Maybe for protecting his consciousness he was imaging the presence of an evil spirit, but at the end he could not do that anymore and is when his degraded mental state is completely reveal.Many people are used to shut themselves away mentally when they are passing through an unwanted situation, but at the end, when they experience a more difficult situation is when the brain cannot protect them anymore, and is when the person collapses. Is important to maintain our brain in good shape, social as well as personal problems are never going to cease, so an intelligent way out is in the use of healthy techniques to improve our mental faculties.

Methods of Lipid Analysis in Food

Methods of lipoid Analysis in Food lipides atomic number 18 define as the biomolecules whose solvability in water is less than that in non-polar solvents. This definition puts structur in ally distinct classes of compounds much(prenominal) as oleaginous bitters, terpenes, steroids, prostaglandins and carotenes in the same class (Carey Giuliano, 2014). early(a) definition for lipidee has also been suggested (Eoin, et al., 2005). They serve a variety of functions in living system including and non hold to structural integrity, life force storage, digestion and communication (Nelson Cox, 2005).Although lipids are essential for many body functions, not all lipids are required in same sum. Food and Agriculture Organization (FAO) recommends that total pad of the nutrition contri simplye to 20-35% of energy for adults. This should entangle 8% saturated super eke outted acid(SFA), 11% poly unsaturated buttery acid (PUFA) and less than 1% trans plunkty acid (TFA) (FAO, 2010). Chances of insulin resistance is to a greater extent in overweight person in high SFA diet (Lovejoy, et al., 2002). Similarly, uppity TFA in progress to also increases the risk of cardiovascular disease (Song, et al., 2015).Fat content also affects preference. It is proposed that fat has a unique taste Oleogustus that is dependent of chain length and is unique from five conventional tastes sweetness, sourness, bitterness, saltiness and umami (Running, Craig, Mattes, 2015). butter produced from milk with high unsaturated fatty acid (UFA) was found to be much(prenominal) spreadable, softer and less viscous (Bobe, Hammond, Freeman, Lindberg, Beitz, 2003).As the fat content and type way outs health as healthful as taste and texture, it is essential to know the fat content of food for thought. Fat take is characterized by a variety of criteria and orders. The natural selection of the criteria and method depends upon the warning type, purpose, accuracy, precision, l egal requirement as head as available funds. and then, despite having limited signifi ejectce for nutritional purpose, total lipid (TL) metrement is widely carried disclose as many food labelling regulations require the TL report. Similarly, iodine value green goddess be apply for unsatu symmetryn study when sophisticated chromatography or spectroscopy methods are unavailable (Greenfield Southgate, check of methods of digest, 2003).This review intends to compile the available methods of lipid summary of food products. Focus will be given on the type of seek required, result provided, resolving message of each criteria and method. Only brief discussion will be d wizard on the theoretical and experimental process of the method.Sample zeal is very essential part of analysis of lipid sample. A erupt section is dedicated to sample preparation. In order to analyze the lipid, suitable sample must be prepared. If the sample has lipid inside cells (such(prenominal) as meat ) the lipid should be extracted from the cells (Christie Han, Lipid Analysis, 2012). Samples must undergo nigh pretreatment before they tail end be use as test sample. Depending on the nature of sample unity or more of the following work is needed.2.1. Storage VesselPlastic container should be strictly avoided to introduce lipids. Plasticizers can leach into the sample and contaminate it. Glass vessels or Teflon coated vessels should be used. The ambiance should be argon or normality to anticipate oxidation. (Christie Han, Lipid Analysis, 2012)2.2. Protection from OxidationUnsaturated fatty acids are prone to oxidation from atmospheric group O. Once the oxidation starts, autocatalysis accelerates the process. Different products are formed during oxidation and it may follow various mechanisms. Light, heat, metals, enzyme are known to catalyze the reaction (Angelo, 1996) Oxidation interferes with lipid analysis not only by destroying the unsaturated fats but also by formati on of conjugated treble bonds which show strong ingress at UV, thus providing false positive results (Christie Han, Lipid Analysis, 2012)Elimination of oxygen is the study step in prevention of oxidation. Therefore, all steps should be done in nitrogen atmosphere as far as possible. Equipment should be flushed with nitrogen before experiments. Small add of antioxidant like 2,6-di-tert-butyl-p-cresol, which do not interfere with analytical process, may be added. Excess of these antioxidant should not be used as they can facilitate oxidation in high concentration. (Christie Han, Lipid Analysis, 2012)2.3. Drying of SampleLipid sample containing water can make analysis difficult and expertness be a tooth root of error. Solvents cannot penetrate sample with 8% moisture easily. Hygroscopic solvents like diethyl ether can absorb the moisture, decreasing its beginning efficiency. Low moisture also facilitates grinding and increases the open air area of sample (Shahidi Wanasindara , 2008). oil color spirit, the most widely used solvent requires completely dried sample. (Greenfield Southgate, Review of methods of analysis, 2003)Depending on the type of water present (free, adsorbed or water of hydration) different methods may be required for water removal (Bradley, Jr, 2010). Care should be interpreted during drying as high temperature might lead to decomposition and combination of lipids with another(prenominal) components. These associated lipids cannot be extracted by solvents. lyophilization (freeze-drying) and vacuum drying methods are favorite(a) drying methods. (Shahidi Wanasindara, 2008)2.4. Particle size reduction (Grinding)Solid food sample might need grinding. Grinding increases the surface area and decreases the length through which solvent need to penetrate the sample (Min Ellefson, 2010). Care should be taken that the particles are not too fine, too much heat is generated or too much moisture is lost. (IUPAC, 1979)2.5. HydrolysisLipids in food may be bound ionically or covalently with non-lipid components such as carbohydrate or protein. Solvents are not able to extract them efficiently. Therefore, lipid needs to be hydrolyzed with acid or alkali to turn them into free state. Significant error in lipid origin is reported when no hydrolysis is carried out. (Min Ellefson, 2010) Hydrolysis also breaks emulsified fat. (Shahidi Wanasindara, 2008)Acid hydrolysis is used for most foods overleap diary and high scratching content food which require alkaline hydrolysis. Hydrolysis is not preferred when the lipid extract needs to be unless analyzed for fatty acid components because they can cause decomposition and oxidation of the sample components. (Greenfield Southgate, Review of methods of analysis, 2003)The given sample of food might not be entirely lipid. The amount of lipid in the food sample is called total lipid concentration. It is usually expressed as fortune or per 100gm food (Moreau, 2005). Although total li pid is widely used for food labelling and regulation of food composition, it has limited value as it does not provide the type of molecule in the lipid. (Greenfield Southgate, Review of methods of analysis, 2003)There are various methods to determine total lipid in food like solvent beginning, non-solvent lineage, instrumental methods. The selection of methods depends on a number of means which is discussed below.3.1. Solvent ExtractionIn solvent extraction, the lipid component of the food is extracted by dissolving in suitable organic solvent(s). The solvent selectively dissolves the lipid while leaving the non-lipid spate undissolved. The solvent is then evaporated to leave fat residue. Total lipid is then determined gravimetrically as-(i)The preceding(prenominal) data gives the total fat. However, a significant portion of the fat includes glycerol (from triglycerides) phospholipids and other unsaponifiable matters. Thus, corrections are required so as to represent the corr ect amount of fatty acids in the sample. The correction factor is provided by FAO. (Greenfield Southgate, Appendix 5, 2003)The extracted portion of solvent extraction is highly dependent on solvent use. Hence selection of solvent is discussed in detail next.Solvent SelectionIdeal solvent should extract all lipids and lipids only. However, due to wide range of polarity of different lipid types, no single solvent can provide an ideal solution. Moreover, the solvent selected should preferably be low boiling, non-flammable, non-toxic in naiant as well as unfaltering, easily disposable after extraction, inexpensive and non- hygroscopic. It should also penetrate sample thoroughly (Min Ellefson, 2010).Petroleum ether is the most commonly used solvent for its selectivity towards lipid, cost and availability. However, diethyl ether is better solvent for lipids but its fire hazard and hygroscopic nature makes it less favorable than oil colour ether. Ethyl ether and petroleum ether is als o some metres used alternately or together for extraction. (Pomeranz Meloan, 1994) n-hexane is preferred for oil extraction. (IUPAC, 1979) medley of polar and non-polar solvents has shown to extract all the lipids from most food. However, care should be given so as to prevent extraction of unwanted portion. The lipids extracted by this method without hydrolysis is suitable for further treatment to determine fatty acid fractions. (Greenfield Southgate, Review of methods of analysis, 2003) Alcohol-ether can be used to remove fat from tissue. Water-butanol is used in cereals. Chloroform-methanol is preferred for fleshly tissue (Pomeranz Meloan, 1994).Solvent extraction is the standard method of analysis for many types of food. Hence, it is widely used and is undergoing consecutive improvement. There are different types of solvent extraction, each with its pros and cons.3.1.1. Batch ExtractionBatch extraction is a very simple, yet widely used method of extraction. The sample is mix ed with one or more solvent which along with endogenous water (if any) forms multiple layer of varying concentration. As the lipids are more soluble in non-polar solvents than in water, lipid portion goes to the layer with more solvents and non-lipid component remains in the layer with more water. The lipid part is then separated using a separating funnel. The separation is establish on partition principle hence multiple extraction of the aqueous phase is necessary to take hold most of the lipid. The weight of lipid not extracted is given by the equation below (Pomeranz Meloan, 1994)-(ii)Where, is the weight of lipid remaining, the volume of aqueous layer, volume of solvent in each extraction step, the distribution ratio of lipid in solvent, the number of extraction steps. The selection of solvent is then done using the distribution ratio of lipids in known solvents.Folch method uses chloroform-methanol extraction followed by washing with water. This extracts all lipid from tiss ue except strandin which remains with the non-lipid phase. (Folch, 1957) Folch method was improved by Bligh and Dyer to improve the speed of extraction and purify the sample at the same duration. (Bligh Dyer, 1959) Extraction using low toxicity solvents like hexane propanol has also been highly-developed. (Hara Radin, 1978)Batch extraction is usually slow and requires a large amount of solvent. When other speedy and easier methods are available, this method is not preferred. However, as no sophisticated equipment is necessary, batch extraction is very useful where the cost of equipment outweighs the usefulness of more accurate data.3.1.2. Continuous ExtractionContinuous solvent extraction recycles the solvent used so that dwarfish amount of solvent can accomplish the equivalent extraction of several steps. This process is preferred for solid samples and sample where the distribution ratio is low. These samples need multi step extraction as very little lipid is extracted to the solvent in each step. (Pomeranz Meloan, 1994)Soxhlet extractor is widely used extractor for lipid. Although first developed to cake milk fat it has developed as a standard extractor for lipid as well as other substances. (Soxhlet, 1879) It has gone various improvements since its first publication and now various modifications are commercially available.Goldfish extraction is a faster extraction system which suspends the sample in the solvent vapour. Although faster than Soxhlet based system, it might not completely extract the lipid due to channeling i.e. solvent may take a preferential path in the solid sample and may not cover firm of the sample. (Moreau, 2005)As continuous extraction is faster and uses less solvents than batch extraction it is the most widely used extraction system. Moreover, the equipment used is not very expensive and can be used for extraction of other materials. However, these processes are slow and disposal of solvent is an everyday problem.3.1.3. Pressur ized Fluid ExtractionPressurized fluid extraction (PLE) is carried out in high pressure and high temperature. In literature, this process is also called Pressurized Solvent Extraction or Accelerated Solvent Extraction. The term ASEis the registered trademark of Dionex Corporation which manufactures pressurized fluid extraction apparatus commercially. (Dean, 2009)Richter et al. studied the effect of variables like temperature, pressure, solvent volume on extraction. Their work showed that the ASE extractor could provide results comparable to Soxhlet but with trim down extraction time and solvent volume. This is attributed to decreased viscosity of solvent, weaker bond among components and increased diffusion qualification of solvent at higher temperature. Increased pressure is primarily applied to keep the solvent liquid, however, it provides the added reinforcement of forcing the solvent into pores blocked by insoluble matter. (Richter, et al., 1996)However, there is evidence th at PLE is not selective to lipids for certain foods. (Boselli, Velazco, Caboni, Lercker, 2001) Moreover, no significant difference was seen on lipid extracted from poultry meat between Folch, Soxlet or ASE method. (Toschi, Bendini, Ricci, Lercker, 2003)Pressurized solvent extraction can be highly useful in labs where routine extraction is required as it greatly reduces the extraction time and solvent use. On the other hand, the investment on the apparatus may not be economical if extraction is not carried out regularly. In all cases the stability of temperature sensitive components should be known before using PLE.3.1.4. Super censorious Fluid ExtractionSubstance in temperature above its critical temperature and pressure is called supercritical fluid. (IUPAC, 1997) Solvent property of supercritical fluid was first demonstrated in 1879. (Hannay Hogarth, 1879) They commence huge prospects in extraction because they combine the solubility power of liquid with penetration power of liquid. Moreover, their solubility can be fine-tuned by changing the pressure and temperature. Carbon dioxide and water are the most lustrous fluid for supercritical extraction due to their non-toxicity and environmentally friendly nature. (Hedrick, Mulcahey, Taylor, 1992)3.2. Non-Solvent Liquid ExtractionIn this method, the sample is treated with some liquid reagent which separates the lipid from sample and the lipid fraction is then measured. This method is for the most part used to determine milk fat. They require specialized vessels for each method and cannot determine phospholipids. (McClements, 2003)Several methods are present3.2.1. Babcock Method3.2.2. Gerber Method3.2.3. Detergent Method3.3. Instrumental MethodsDifferent instrumental methods have been developed to determine the total lipid content of the sample. They rely on some physical properties that vary consistently with lipid concentration. (McClements, 2003)Based on the property measured it is mainly of three type s3.3.1. Measuring Bulk Properties immersion concentration decreases as lipid content increases. This relation can be used to know the percentage of fat in a sample. (McClements, 2003)Electrical Conductivity Conductivity decreases as lipid content increases. Thus, it can be used as fat concentration measure. (McClements, 2003)Ultrasonic Velocity This is a fast and non-invasive method for fat content calculation. Amplitude and brightness analysis can be used to happen the fat content and also distribution. (Abdul, N, Mohd, Abu, Z, 2013) Moreover, attenuation(absorption) of ultrasound is linearly proportional to the amount of fat in the body. (Dukhin, Goetz, Travers, 2013)3.3.2. Measuring ducking of RadiationUV-VIS Fatty Acid absorb UV light proportional to its concentration. This method requires sample preparation to remove substances like proteins and hydrophobic peptides which interfere with the measurement. (Forcato, Carmine, Echeverria, Pecora, Kivatinitz, 2005) Because of t he extraction and dilution needed the process can be time consuming and labor intensive. (McClements, 2003)IR Near infrared (NIR) spectroscopy is mainly used to analyze fatty acid content in food. (Mossoba, Azizian, Kramer, 2012) Fat show strong absorbance at 5.74 mm which provides rapid and online fat composition measure. (McClements, 2003) The carbonyl absorption is the major reason for lipids NIR activity. This method requires intensive calibration with other sanction methods hence is mainly used for routine analyses of large number of similar sample. (Greenfield Southgate, Review of methods of analysis, 2003) nu wakeful magnetic resonance NMR is also a non-destructive and fast method of total fat analysis. Although it requires a calibration curve, it is better accommodate than IR or UV because it can be operated by non-experts and the calibration curve is long lasting. (Oxford Instuments molecular(a)(a) Biotools, 2010)X-Ray Fat absorbs less X-Ray than lean meat. Hence, by building a proper calibration curve, fat content in meat can be determined by X-Ray absorption (McClements, 2003)3.3.3. Measuring Scattering of RadiationLight and Ultrasonic Scattering Light as well as ultrasound waves are scattered by oil droplets present in emulsions. The linear relation between concentration of droplet and light scattering can be used to measure total fat, provided no other interfering molecules exist. (McClements, 2003)X-Ray Fat molecules show a sharp X-Ray scattering peak at 1.1 nm-1 while a water rich tissue shows a peak at 1.6nm-1. Thus, varying amount of fat can give a scattering profile which can be used for fat content determination. (Elshemey, 2011)3.4. Other Methods3.4.1. Solid Phase Extraction3.4.2. Microwave Assisted ExtractionTotal Lipid Concentration is a very simple data about food. As lipid contain diverse chemical species, in addition to total lipid, the type of lipid and their distribution also plays a major role to determine the purity, nutriti onal value, aesthetic look and taste. Hence, complete information about the type of lipids is necessary for scientist as well as legal bodies. (McClements, 2003)Sample preparation is the most important part in most method to analyses lipids. As the lipid is extracted, care should be given to prevent the change of one form of lipid to another. Hydrolysis should be rigorously prevented as it reduces triglycerides and increases free fatty acids. Extraction should cause as less oxidation as possible. (Greenfield Southgate, Review of methods of analysis, 2003) Extraction in chloroform, chloroform-methanol and hexane-isopropanol is preferred. Storage of sample in polar at -20oC is preferred. (AAFCO Lab Methods Services Committee, 2014) The various method present have their advantages and drawbacks and the preferable method depends on the type of food and the type of lipid to me examined, (Greenfield Southgate, Review of methods of analysis, 2003)4.1. ChromatographyIt is a very powerfu l tool for lipid analysis. It can give compete profile of the lipid molecules in the given sample. Chromatography separates the different components of lipid in fractions, these are then subject to spectrometric analysis which gives the molecular identity as well as relative concentration. IR, NMR and Mass Spectrometry are most commonly used. (McClements, 2003) These methods, although very reliable and cosmopolitan are very expensive due to the instrumental and reagent cost and is only carried out where complete molecular identification is required. (Greenfield Southgate, Review of methods of analysis, 2003)Three types are usedtender loving care Thin Layer Chromatography is used to find concentration of different lipid groups. The TLC eggshell is prepared with suitable adsorbent and kept in proper solvent. A drop of sample is placed on one end and let to flow. The plate after separation to different fractions is compared to standard plates to identify the lipids. The spots can be analyzed further by GC, MS, NMR. (McClements, 2003) After the advent of HPLC, TLC use has decreased considerably. However, after the availability of pre-coated plates, the use of TLC for instant result is still carried out when there are few samples only. It is cheaper than HPLC. However, care during experimentation is required. (Christie, Thin-Layer Chromatography of Lipids, 2011) This method cannot be used to separate different types of phospholipids. (Zaima, Goto-Inoue, Adachi, Mitsutoshi, 2011)HPLC High Performance Liquid Chromatography is now a preferred method for lipid analysis. This is because it is more versatile than TLC and operates at room temperature, thus can be used to analyses labile groups that cannot be done using GC. (Christie, Thin-Layer Chromatography of Lipids, 2011)GC Gas Chromatography is the preferred method for analysis of trans fatty acid. It can also be used for triglycerides and fatty acids however, methylation is necessary. (Greenfield Southgate, Rev iew of methods of analysis, 2003) Fatty acids are non-volatile, hence before carrying out GC, the lipids are saponified and methylated to give Fatty Acid Methyl Esters(FAME) which are volatile and can be used for GC. (McClements, 2003) -(2)It is now possible to convert a lipid sample of a fraction of a milligram in size to the methyl ester derivatives, separate these by gas chromatography, and have a quantitative result in under one hour. (Christie, Chapter 1 Introduction and Summary, 2011)4.2. chemical MethodsThese methods are very cheap and do not require expensive machinery. However, only crude and intermediate results are obtained.Following test gives different information on fatIodine Value It gives the fairish degree of unsaturation in the lipid. The lipid to be analyzed is titrated with ICl and the consumption of ICl gives the amount of unsaturation in lipid.Saponification Number It gives the fair(a) molecular weight of triglycerols. The triglycerols are saponified with K OH and the amount of KOH used is determined. This is the saponification number. High saponification number corresponds to low molecular weight and vice versa.Acid Value It gives the amount of free fatty acid. Here, the lipid is titrated with KOH until the solution turns alkaline. Other acids may interfere with results.(McClements, 2003)4.3. Instrumental TechniquesVarious instrumental techniques for fat analysis are present. Methods like NMR, IR, MS are usually coupled with chromatography. Measurement of density and refractive index can be used to measure change in chain length and unsaturation. (McClements, 2003)Lipids with high unsaturation undergoes aerial oxidation. This includes variety of reactions usually summarized as followsreactants primary products secondary products(unsaturated lipids and O2) (hydrogen peroxides and conjugated dienes) (ketones, aldehydes, alcohols, hydrocarbons)5.1. ChromatographyLoss of reactants as well as formation of specific products can be monit ored by using time profile.5.2. Oxygen UptakeMeasures the amount of oxygen consumed over time while maintaining constant oxygen concentration on the reaction vessel.5.3. Peroxide ValueMeasures the amount of peroxide formed by titration with iodine.5.4. Conjugated DienesMeasures the concentration of conjugated dienes by UV spectroscopy (at 233nm for diene and 268nm for trines)5.5. Thiobarbituric Acid(TBA)Measures the secondary products (aldehydes) in the sample. The sample is treated with TBA and absorbance measured at 540nm. The absorbance value corresponds with the concentration of aldehyde.5.6. Accelerated Oxidation TestsThe sample is oxidate in oxidation friendly environment and the time taken for rancidity to form is measured.These tests help to know the physicochemical characteristics corresponding to flavor, appearance, flow etc.6.1. Solid Fat Content(SFC)Measures the fraction of fat present as solid. Density measure is mostly used(3)Where is the density at given temperature and are the density if it was completely liquid or solid at the same temperature.NMR signal decay rate is also be used recently. More solid component, faster is the signal decay.Differential Scanning Calorimetry uses latent heat measure are also used to measure SFC-temperature profile.6.2. Melting PointUsed when SFC is not required but only the temperature of melting is required. Due to different components present no sharp melting height is seen. preferably different melting points are usedClear Point The temperature at which fat completely melts and becomes clearSlip point The temperature at which the fat in a capillary tube starts to slip.Wiley melting point the temperature at which a disc suspended in alcohol-water mixture turns to a sphere.6.3. Cloud PointThe temperature at which a completely melted lipid starts to develop turbidity.6.4. Smoke PointThe temperature at which the lipid starts to stinker at standard condition6.5. Flash PointThe temperature at which a flash ap pears on the surface at ignition at standard condition6.6. Fire PointThe temperature at which a continuous flame stats to form at standard condition6.7. RheologyThe measure of deformation and flow. Viscosity, elastic modulus and other pertinent flow or plasticity measure is used.(n.d.).
