The cultural relevance of the Bic Maxi lighter According to William J. Thomson, the natives of Easter Island’s “method of obtaining fire requires considerable preparation of material and patience on the part of the operator. A pointed stick of hard wood is rubbed against a piece of dry paper-mulberry until a groove, is formed, which finally becomes hot from the friction and ignites the lint or fiber thrown up at the end of the groove. This is blown into a flame, and dried grass added to it until
Ethylene, H2 C = CH2, the lightest olefin. It is a colorless, flammable gas, produced mainly by thermal decomposition in the presence of steam (steam cracking) from petroleum-based raw materials. Ethylene has virtually no direct inhalation, but almost exclusively acts as an intermediate in the production of other chemicals, especially plastics. Polyethylene, which is the most commonly used plastic, is directly produced from ethylene by its polymerization. Ethylene can also be chlorinated or combined
CHEMISTRY ISU: REFINEMENT OF CRUDE OIL My ISU will focus on Petroleum, a complex mixture of hydrocarbons that occurs in the Earth in liquid, gaseous, or solid forms. The term is usually restricted to the liquid form, commonly called crude oil, but as a technical term it also includes natural gas and the viscous or solid form known as bitumen. In its liquid and gaseous states, it is also known as Oil, or Crude Oil. Italicized are segments from my ISU or introductions to the planned topics. In my
Between March and June 2006, three loads of 28,000 tons of Coker Naphtha were put on board Probo Koala, a cargo ship owned by Trafigura. Caustic soda and other chemicals are used to clean the Coker Naphtha to make it into gasoline. This process of cleaning the Coker Naphtha produced 500 tons of toxic waste. Later Trafigura was facing a problem of how to safely dispose of all this toxic material. Amsterdam Port Services
"War is the father of all things."1 Volkman begins his book, Science Goes to War, with this quote from Heraclitus, the Greek philosopher. Volkman uses the quote to suggest that many, if not all, scientific advancements owe their birth to the desire for or the fear of war. Fire is undoubtedly a part of this advancement as Bert Hall points out, "Fire is one of the primordial forces of nature, and incendiary weapons have had a place in armies' toolkits for almost as long as civilized states have made
Case Studies: 1) IFFCO: Indian Farmers Fertiliser Co-operative Limited (IFFCO) was registered on November 3, 1967 as a Multi-unit Co-operative Society. The Society is primarily engaged in production and distribution of fertilisers. It is a unique venture in which the farmers of the country through their own co operative societies created this new institution to safeguard their interests. (IFFCO 2013) Plants owned by IFFCO: • Kalol Unit (Ammonia - Urea complex) in the state of Gujarat in 1975. •
Crude Oil Crude oil is a complex mixture of hydrocarbon molecules formed over millions of years when the remains of microscopic sea creatures trapped in sediments were converted by heat and pressure into crude oil. The most abundant of these mixtures are the ones containing hydrogen and carbon only. These hydrocarbons can take on a number of different forms, i.e. alkanes, alkenes and alkynes. They vary in size and shape and viscosity. By manipulating these chains of hydrocarbons you
The History and Advantages of Electric Cars Early electric vehicles may have appeared as early as 1830. Scottish inventor Robert Davidson constructed the world's first prototype electric vehicle in 1837, but historians generally credit J.K. Starley, an English inventor, and Fred M. Kimball of Boston with building the first practical electric cars in 1888. Later in the in the decade, William Morrison of Des Moines, Iowa, constructed his version of the electric vehicle in 1891. His vehicle required
oil industry to take advantage of all the products that can be extracted from a crude oil. In a column distillation, at different temperature, we can obtain various compounds that we use in our daily life, such as gases(butane), petroleum (cars), naphtha (chemicals), kerosene (jet fuel), diesel (trucks), fuel oil (power station), and residue (roads, and bitumen). 11. What is a gas chromatography used for? How does it work? (2 pts) A gas chromatography (GC) is used for a quantitative analysis to
low temperature and pressure and the product yielded is translucent, but readily colored. Differences in catalyst and production conditions can be used to alter the properties of the plastic. Propylene is obtained, along with ethylene, by cracking naphtha (crude oil light distillate). Ethylene, propylene, and higher alkenes are separated by low temperature fractional distillation.[3] Polypropylene is a relatively easy material to injection mold in spite of its semi crystalline nature. The absence of
home there are no radios, televisions, or any other modern appliances. Coal, gas, or oii powered heaters are their only sources of heat. The Amish also have gas-powered refrigerators. Kerosene lamps or lamps are their main sources of light that burn naphtha. The Amish don't have no running water other than a small water pump that is used in the kitchen. Other sources of water must be pumped from an outdoor pump and carried into the house. Meals are prepared and eaten in the kitchen, the largest and most
Quick Summary : Wow, hard task to make a cute summary one such a book.

bow was could reach up to 250 meters, which was twice the distance of the English bowlongs. There were various types of arrowheads that were used such as ones that were able to whistle in air, pierce through armor, or arrowheads that were dipped in naphtha and set on fire. Another device the Mongols were introduced to was gunpowder, which was utilized as an explosive, rather being used for cannons. In addition, the Mongol Empire also relied greatly on a secure network of communication, as Mongol scouts
1.1 Chip Sealing Chip seals have been used since the year 1920’s in the United States when they were used as a stratum for low volume gravel roads. Since then it has been used proudly both as a new paving process and as a precautionary handling treatment for existing pavements. In Iceland, chip sealing was first used in 1978 when a 15 km section was paved in southern Iceland. Chip seals are mostly used on low volume roadways with ADT<5,000 although some nations like South Africa and Australia use
Commercial demulsifiers are formulated in solvents such as short-chain alcohols, aromatics, or heavy aromatic naphtha and can contain a mixture of several active matters. There have three main methods to demulsify the emulsion namely mechanical, electrical and chemical. However, chemical method is most widely used. Basically, chemical demulsification consist of the
1.1 Porter’s five force analysis According to Porters analysis, there are five basic factors affecting the operations of an organisation in any given market. These factors are bargaining power of suppliers, bargaining power of buyers/consumers, threat of competitive rivalry, threat of substitutes and threat of new entrants. 1.2 Bargaining power of suppliers The bargaining power of L & T suppliers is high. Most L & T suppliers are organised making the company to be one of the largest engineering companies

Genghis Kahn conquered a total of 4,860,000 square miles. That’s more than two times the amount lassoed by Alexander the Great, the second most successful conquerer. The amount of land that Genghis Kahn conquered is over one million square miles greater than the entire area of the United States, Alaska and Hawaii not included. (doc A) The pain inflicted by Khan and his army during their conquests was unfathomably merciless, demented, and “barbaric.” His victories resulted from actions and inhumane
