The role of mass customization and postponement in global logistics
The role of mass customization and postponement in global logistics "Mass Customisation is - the customisation and personalisation of products and services - for individual customers at a mass production price. So, what does mass customisation mean for manufacturers and retailers? Simply this, that there's money to be made and customer satisfaction to be achieved by allowing the buyer to customise his or her own purchases by choosing the size, colour and style from a predetermined, often extensive, list of 'options'. The ultimate goal is to manufacture on a mass scale, retain or improve the margins associated with mass production, and supply a final product that meets each buyer's individual desires. Apparel captures a major share of mass-customised products, but the concept stretches far beyond a single industry - to furniture, automobiles, eyeglasses, aeronautics, Barbie dolls, computers and so on. For the manufacturer, mass customisation offers an advantage because it differentiates his product from that of his competitors. It enables him to charge a premium for allowing his customer the 'privilege' to specify the final details of his purchase. Moreover, it allows the consumer to 'buy in' emotionally to the purchase, thereby reducing the risk that he will return the product he's purchased - forcing the manufacturer to restock or mark down, or even worse scrap, the

Chemical Detection Uttam Sharma CHEMICAL DETECTION Introduction In this CDA, I will attempt to explain everything about our experiments which we performed in class. We did these experiments in order to identify the substance present Our experiment consisted of two samples of water containing unknown substances, and our objective was to identify the compound present in the substance. Since the substance was dissolved in water, we had to separate the water from the substance, and then execute a series of tests which would eventually help us to determine the substance in the sample. Water Water (H20) is vital for all types of life, animals and plants. A molecule of it is made up of two hydrogen atoms and one oxygen atom. It has freezing point of 0°C and a boiling point of 100°C at sea level (on top of Mount Everest it boils at just 68?, due to changes in atmospheric pressure). Water covers 71% of the Earth's surface and is colourless and odourless (no smell). It is used every day for drinking, washing up, farming and in many other important places. This is where hard and soft is important. Hard water is water that contains large amounts of minerals. Mostly it comprises of are the cations of calcium (Ca2+) and magnesium (Mg2+). There are other metals present in hard water such as bicarbonates and sulphates. Calcium comes into the water through in the form of limestone
What "Carried the Trick"? Mass exploitation and the decline of thought in Ray Bradbury's 'Fahrenheit 451.'
What "Carried the Trick"? Mass exploitation and the decline of thought in Ray Bradbury's 'Fahrenheit 451.' * There is an interesting dichotomy in Ray Bradbury's 1953 Fahrenheit 451, a noticeable gap between the message that the author and we the readers receive from the novel and the message that the text actually seems to support. While I realize that some see little use for such old-fashioned attention to the text itself, Fahrenheit 451 is such an overtly didactic work that it almost invites such examination. Surely even the staunchest reader-response critic would agree that Bradbury is trying to sell the readers on ideas that he has put into his story. Yet there is a discrepancy between the ideas the author is selling--and readers are buying--and the ideas he has let the whole rest of the text support. I suggest this not necessarily to label it as a weakness but to show that the novel is thereby just a little bit richer and probably truer to life than many have supposed. The discrepancy lies in the book's subtle treatment of the relationship between mass exploitation and the decline of thought. Fire Captain Beatty, the novel's chief book-burner, explains that "technology, mass exploitation, and minority pressure carried the trick" of supplanting independent thought with conformity and leading to censorship (58). Clearly Bradbury wants us to notice these three culprits in
Periodic table
Chemistry In the beginning a long time ago before cars and mobile phones, students spent all day learning about the matter that made up the earth. They had long lessons, wore funny clothes and only had religious holidays. Alchemists people who made up weird potions to live forever or make gold. At the same time a man named Democritus (A teacher) suggested everything in the world was made up of tiny particles that could not be seen. He called them atoms 2000 years later Democritus idea was correct. Scientists today don't rely on weird potions and secret spaces with cauldrons instead they rely on investigations carried out with careful observations. Today there are 112 known elements Building Blocks Atoms are joined together in groups called molecules Atoms can join together to form elements or large molecules of many different shapes Polymer scientific word to describe large molecules e.g. Rubber, Cotton Questions .

An experiment to investigate the factors that determine the amount of energy released when alcohols are burned Planning Background Knowledge All hydrocarbons contain carbon atoms in a chain that have formed bonds with other hydrogen atoms to become stable large molecules. Methane consists of only one carbon atom: Methane (CH4) Hydrocarbons with more than one carbon atom form a carbon chain within the molecule. Here, the carbon atoms form a bond with each other to form a chain, and each atom forms bonds with other hydrogen atoms to become stable. Ethane contains 2 carbon atoms in a chain whereas as propane contains 3 and butane contains 4: Ethane (C2H6) Propane (C3H8) Butane (C4H10) The number of carbons in a chain in a hydrocarbon may be very large and also has more hydrogen atoms bonding with the carbon atoms to make the molecule stable. We can find a relation between the number of carbons in the hydrocarbon and the number of hydrogens. From the structural formulas of methane, ethane and propane above, we can see that for each carbon atom, two hydrogen atoms are included to form bonds with it plus an extra hydrogen atom for each of the carbon atoms on each end of the carbon chain. This gives the formula: CnH2n + 2 where n is equal to the number of carbon atoms in a chain. This rule applies to all hydrocarbons provided that
Rate of reaction of different concentrations of sodium thiosulphate.
Science Coursework: Rate of Reaction The aim of the experiment: In this experiment I will investigate how different concentrations of sodium thiosulphate affects the time for the cross on a piece of paper to disappear. The sodium thiosulphate's concentration will vary in the stages of the experiment as proportions of water will be diluted with the chemical to see how it effects the time of the visibility of the cross. Prediction: I predict the higher the concentration of the sodium thiosulphate the faster the rate of reaction therefore shorter the time will be for the cross (x) to disappear. Background Information: Sodium thiosulphate is a liquid so its particles will be in constant motion. Before a reaction can occur between two liquids their particles must collide together in order to create a reaction. It is not enough for the particles to collide, the bonds between the atoms they have to be broken before new molecules can be produced. In liquids and gases their particles are continually moving at various speeds, which then collide in different ways. There are different ways of collisions occurring which have different effects such as 'head on' and 'glancing' collisions. The particles that contain a lot of kinetic energy (at a high temperature) collide with a large force therefore gain a heavy contact with another particle (head on). This is known to be successful
Rate of reaction of hydrochloric acid on magnesium.
Science Coursework: Rate of Reaction The Aim of the experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium, from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time interval. Overview of the experiment: In this reaction two substances will be present in the solution, magnesium and hydrochloric acid. During the reaction magnesium particles will collide with the hydrochloric acid particles to produce the salt Mg chloride and hydrogen gas. The amount of gas will be monitored at certain time intervals to find out the rate of reaction. However I will be changing the molarity of the HCl by diluting it with water. The water molecules will prevent the Mg and HCl particles to collide, this is because the water molecules will get in the way of the collisions therefore providing an obstacle for the two reacting particle. This will have an influence on the rate of reaction it will make it slower. Background information: Magnesium is in the group 2 metals that are quite similar to group 1 metals in the periodic
should salt be banned?
Should Salt Be Banned? Salt. When you hear the word, what thoughts come to mind? "Too much salt is bad for me." Or, "That reminds me, I've got to check my bid on Ebay for that Elvis salt & pepper shaker set that I simply must have." Heck, maybe you even have one of these lines, "My grandad lived to the ripe ole' age of ninety-six and he put salt on everything from pasta to pickled pigs feet." That pretty much sums up salt's MO. There are those who think it's bad and limit their exposure to it, and then there are others who dump it on everything. Now who's right? In this report I shall attempt to find out, and decide whether salt should be banned. The salt cellar should be ditched from the family dinner table in a bid to improve health, according to many cancer experts. Diners should stick with pepper mills only and leave salt off their food, according to World Cancer Research Fund (WCRF) medical and scientific adviser Professor Martin Wiseman. Adults should eat no more than 6g of salt a day, but many people in the UK get through far more. About 10 to 15% of salt intake is added at the dinner table or during cooking, the WCRF said. Prof Wiseman said, "Basically we would say don't use salt, try to use other things that will add flavour. "Because salt is added by food manufacturers, there is too much of it in our food before it even reaches our dinner table. "But by adding
GCSE Chemistry - Obtaining Zinc Oxide from Calamine
Chemistry coursework Obtaining Zink Oxide from Calamine Jacob Confino 1d Planning Introduction: Before zinc was recognized as an element zinc ores were used for making brass, which was a mixture of copper and zinc. Calamine is a mineral, which is mainly composed of the compound calamine, which has the formula ZnCO3. The metal zinc is extracted industrially. If you heat calamine it decomposes into zinc oxide and also carbon dioxide. This sort of reaction has a reaction and its formula is: ZnCO3(s) ZnO(s) + CO2(g) This gives you the calculation of the theoretical mass of zinc oxide, which is obtainable if you heat the mass of calamine. I am going to heat up gram by gram of calamine and see how the reaction changes as the amount of calamine is added. I am going to start with 1 gram in a boiling tube, then I will heat it until it changes colour to yellow (which shows that the reaction has taken place), then I will put it in my test tube rack until it changes back to its original colour (white) I will then go and take a reading to see how much it weighs. I will then see how much the weight has gone down by. Then I will reheat it until the weight does not go down anymore, then I know that I have obtained the most zinc oxide possible. Aim: The aim of this experiment is to produce a conversion chart, which shows how much zinc oxide can be
