The Importance Of Fuel And Technology Environmental Sciences Essay
The Importance Of Fuel And Technology Environmental Sciences Essay I am researching these topics because it has a lot in common. Fuel energy and technology is a very interesting topic, they are the most useful things by human being, it is used for important things and this will help me know more about the history of fuel and technology, I am a person that likes a lot technology because is different of other things. Without technology, fossil fuels cannot be extracted in an easier way because technology gives details of ground and how fuels companies can extract petroleum from the earth. Fossil fuels provides 66% of the world electrical power and 95% of the world energy demand and we need to have in count that fuel energy and technology is our principal source of transportation. Fossil fuels, coal, oil and natural gas, are a non-renewable source of energy. Formed from plants and animals that lived up to 300 million years ago, fossil fuels are found in deposits beneath the earth. The fuels are burned to release the chemical energy that is stored within this resource. Energy is essential to modern society as we know it. Over 85% of our energy demands are met by the combustion of fossil fuels. Fuel is one of the most used earth product because in the entire world fuel energy is used to make a lot of important things such as vehicles gas, cells, etc. Fuel is any material that can be used to generate energy to produce mechanical work in a controlled manner and the processes used to convert fuel into energy include chemical reactions, such as combustion, and nuclear reactions, such as nuclear fission or nuclear fusion. Fuels are also used in the cells of organisms in a process known as metabolism. Hydrocarbons are by far the most common source of fuel in current u se, but many other substances can be used as well. The most interesting case about fuel energy is how it was create or how human being in the past thousand years has the incredible idea to perform energy source, fuel energy was first starts with wood. It was one of the first fuels used by humans and is still the primary energy source in much of the world. These discover was performed by home erectus near 2 million years ago. A very important thing to say is that without fuel, our technology never will be developed because without that, cars, airplanes and all types of vehicles will not work. Fossil fuels exist long before dinosaurs roamed the Earth. These are made up of plant and animal matter. When plants and animals died, their bodies decomposed and were buried under layers of earth. Millions of years later we have the three forms of fossil fuel: Oil, Natural gas and Coal. The advantages of fossil fuels is that they produces a lot of electricity especially coal, its cheap, transporting coal and gas is easy and power station that run on gas are very efficient and the disadvantages is that burning fossil fuels produces carbon dioxide which result in greenhouse gases that mean global warning alert, burning coal produce more carbon dioxide than gas and oil and it also produces sulphur dioxide that causes acid rain. According to scientists burning fossil fuels produces 20 billion of carbon dioxide every year and the earth natural process can only absorbs 20 billion tons of carbon dioxide and the remaining carbon dioxide goes to the atmosphere and contributes to global warni ng. The oil is found way down in the ground, usually between layers of rock. To get oil out, a well is dug. Digging a well is like putting a straw into a can of pop. The oil is then pumped out of the ground, just like when you suck pop up the straw. Oil is carried in pipelines and large tanker ships. A refinery changes the oil into products like gasoline, jet fuel and diesel fuel. Its also burned in factories and power plants to make electricity Natural gas is made out of methane, which is a simple chemical compound made up of carbon and hydrogen atoms and this gas is highly flammable. Natural gas is found near oil in the ground. Its pumped, just like oil, from wells that tap into the source and send it to large pipelines. Because you cant smell or see natural gas, it is mixed with a chemical to give it a stinky smell like rotten eggs. For thousands of years man has depended on fossil fuels as his primary energy source. Chapter 3Ãâà Technology Technology is the process by which humans modify nature to meet their needs and wants. Technology means computers and software, aircraft, pesticides, plasma TVs, birth-control pills, and microwave ovens, to name a few. But technology is more than these tangible products. Human being has found the correct way to make life easier and effective. Technology is what the world needs to develop in the faster and easier way, with technology everything can become possible and everyday technology is growing up. The use of the term technology has changed significantly over the last 200 years. Before the 20th century, the term was uncommon in English, and usually referred to the description or study of the useful arts. Technology is meant to be our future of our life. Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines t hat may be used to solve real-world problems. With technology this world will have a better future and we will have a better lifestyle with a healthy and long life because technology is what is changing this world. It is true that technology is also bringing a lot of problems for todays young society because they are getting in their own world using internet, PlayStation etcâ⬠¦this is making childhood to be dependent of themselves and they dont do activities like sports going out with friends or interacting with family so this is the mayor problem of technology, people are getting addicted of excessive uses of technology because is more easier so they get lazy. It is the current state of humanitys knowledge of how to combine resources to produce desired products, to solve problems, fulfill needs, or satisfies wants. It includes technical methods, skills, processes, techniques, tools and raw materials. Conclusion In the world exist a lot of problems about global warming and this is happening because fuel energy extract, but we can be intelligent and take care of our planet and contributes in saving water, dont destroying our habitat, the world is created for us to live and is our home so it is incredible how humanity is destroying the world without thinking of a world destruction or humanity destruction. Fuel energy and technology is of great importance in the entire world because without this our advanced things like computers, motor vehicles, electronic devices, internet our world will not work as efficient as it is working todays days, everything is easier than the last 100 years. These two resources give a great contribution to the world. Technology gives a better way of communication and fuel a better way of transportation.

Digital Communication
Joshua Feliciano ââ¬â 110445 Mr. Basile IB ITGS ââ¬â 11 4. 27. 2010 Digital Communication in the 21st century Digital communication can be defined as an electronic transmission of information that has been encoded digitally. This specifically means that digital communication is data communication of information that is converted from text to code digitally. Digital communication can also be effective communication dealing with web, multimedia, video or graphics, and digital media. Some forms of digital communication can be texting, IM, e-mail, podcasting etc. Digital communication plays an important part in today's daily life in many different perspectives. In today's age, most people find digital communication a lot more easier and teachers and professors find it a bit more comprehensive. Todayââ¬â¢s companies and organizations, use different types of media to reach and retain their audience. Digital communication helps jobs and businesses communicate a lot faster through e-mail, multimedia, texting, power point, presentations etc. As for students in any school or college, all these digital communication advantages also help and make it a lot more accessible. Throughout the decades, technology has improved drastically and gets more highly skilled as time goes on. In the past there was no such thing as digital communication. All communication was through hand written letters, phone calls, or people would just have to go visit whoever it is in person. Digital communication has made a huge change and difference in today's age. Its more comprehended and explanatory. In today's society a lot more can be accomplished with the digital communication and technology that exists today. Some of these digital communications can be text messaging, video or graphics, multimedia, podcasting, and digital media. Back then in about the 1990's, there was no such thing as any of these digital communications and advantages. Video or graphics and multimedia may have been in useable but, it definitely wasn't as advanced, updated, or even in good picture quality as today's technology and digital communication. This is significant in a couple of different ways. Not only is everything faster, and looks nicer but, all the improved technology saves every individual a lot of time in their life. With all the development and improved technology, digital communication has really made a difference for people in today's age. Digital communication contains many advantages and disadvantages. Some being good and others being bad. Advantages of digital communication can be that it is faster and easier, no paper is wasted, messages can be stored in the device for longer times without being damaged unlike paper files that easily get damages, it can be done over large distances through internet and other things, it is comparatively cheaper and the work which requires a lot of people can be done simply by one person as folders and other such facilities can be maintained, and it provides facilities like video conferencing which save a lot of time, money and effort. Digital communication also contains many disadvantages which can be that it is unreliable as the messages cannot be recognised by signatures, sometimes the quickness of digital communication is harmful as messages can be sent with the click of a mouse, it has completely ignored the human touch in which a personal touch cannot be established because all the computers will have the same font, and greater bandwidth. In conclusion, digital communication can be defined as the ability to create communications in different media, which can be its websites, video, audio, text, or animated multimedia. It's important in today's society because it's much faster and more understanding other than having to deal with letters that you can't comprehend. In today's age, digital communication can be more visible and more fun with the advancement of video or graphics, multimedia, podcasting text messaging, e-mail etc. This is significant because everything is much faster and more advanced. Overall digital communication had its advantages and disadvantages some being good and some being bad which in the end was still a very successful improvement of today's technology.

The Origins Of Supply Chain Management Commerce Essay
Harmonizing to, Mentzer et Al. SCM is concerned to convey profitableness and competitory advantage through bettering the efficiency and effectivity in a strategic context. Thomas and Griffin ( 1996 ) , argued that supply concatenation can assist the organisation to minimise their operational cost and supply better client services, through coordinated planning and they found cognition is critical point for organizing and be aftering between the supply concatenation spouses.The Origins of Supply Chain Management:Supply concatenation direction started to emerged in the 80s 0f the last century, nevertheless, in the last 10 old ages supply concatenation direction has become really celebrated in direction literature ( Cooper et al. , 1997 ) . Supply concatenation direction started to emerged at first through constructing a partnership and coaction between the industrial and service company and their providers, by integrated all the histrions procedures and maps, which create the buying att ack of the supply concatenation direction, the chief thoughts of supply concatenation direction are just-in-time, zero stock list, uninterrupted refilling, and cut costs through extinguishing extra clip, excess attempts and buffer stock list, secondly these organisations besides built a strong integrating with their jobbers and retail merchants, which the research workers name it the logistic attack of the supply concatenation direction, and the chief end was to better client service through supplying options, visibleness and fast bringing, thirdly the integrating attack of supply concatenation direction which demonstrate all of the value adding procedures from traveling the row stuffs from providers through fabrication or service suppliers company until the terminal users, and the critical end is to derive a new competitory advantages, ( Thomas and Griffin,1996, Tan, 2001 ) Furthermore, supply concatenation direction aimed to bettering concern public presentation and competitory advantage through integrating several procedures such as planning, planing, logistic, production, and merchandising ( Lambert & A ; Cooper, 2000 ; Lim, 2007 ) , Supply concatenation direction coordinates the procedure of mutualist decision-making, organizes several supply concatenation spouses and manages information and stuffs flow ( Chandra & A ; Kumar, 2001 ) . In fact, many research workers and practicians have position SCM as an of import topic in their research country ( Li, 2002 ) . Presently, supply concatenation direction has become an of import modern concern constructs. aaââ¬Å¡Ã ¬Aââ¬Å"SCM is a system that contains multiple entities, procedures and activities from providers to clients. The basic construct behind SCM is how the natural stuffs and information flow from the provider to the maker, before concluding distributions to clients as finished merchandises or services. In add-on, functional countries within the organisation besides need information that flows through the SCM in order for them to do a determination to bring forth merchandises. The capableness of sharing and interchanging information is indispensable to better the effectivity of the SCMaaââ¬Å¡Ã ¬A? ( Udin et al. , 2006 ) . Supply concatenation can be viewed as a web incorporating providers, makers, distributers, retail merchants, and clients. Concisely, a supply concatenation is the rhythm of buy-make-move-store-sell ( Akkermans et al. , 2000 ; Sheikh, 2003 ) . Based on the above, we emphasis that such this integrating includes, the row stuffs and money as a touchable resources, and the cognition and information as an intangible resources which the supply concatenation by pull offing these resources in efficient and effectual manner will derive a competitory advantages which can better the supply concatenation public presentation. Harmonizing to Schroeder ( 2000 ) , Supply concatenation is a series of concern procedures and information that assist the organisation to supply goods and services in the supply concatenation which comes through providers, makers, distributers, retail merchants and eventually end-customer, Throughout the supply concatenation the concern environment alterations and the supply concatenation design as opposed to provide concatenation coordination is going a nucleus competitory advantage which force organisations to pull off and incorporate their supply concatenation efficaciously ( Fine, 1998 ) . The above Figure shows the supply concatenation web supports three sorts of flows at the operational degree which requires careful planning and strong coordination, these flows presented as the followers: Material flows: including the flow of physical merchandises from providers to clients and besides the opposite flow of returning, having, and recycling merchandises. Information flows: affecting the flow of information sing order trailing and transmittal. This information coordinates the physical flow of merchandises. Fiscal flows: which encompass the flow of recognition footings, payment agenda, cargo, and title ownership understanding. The same Figure ( 1 ) besides explains that, supply concatenation web is supported by three props as follows: Procedures, consisting merchandise development, cognition direction and logistics. Organizational constructions, dwelling of relationship, integrating, webs, direction attacks, public presentation measuring, and reward strategies. Enabling engineering, consisting procedure and information engineering. Supply concatenation direction aaââ¬Å¡Ã ¬Aââ¬Å"is the integrating of cardinal concern procedures from terminal user through original providers that provides merchandises, services, and information that add value for clients and other stakeholdersaaââ¬Å¡Ã ¬A? ( Lambert & A ; Cooper, 2000 ) . Based on the above conceptualisation, it is clear that supply concatenation direction is all about integrating, in other words, integrating is an of import portion in SCM. Therefore, efficient integrating in the supply concatenation could take to successful and effectual SCM public presentation. Therefore, in order to accomplish efficient integrating and so successful SCM, companies need to implement cognition direction processes because these procedures such as cognition sharing, creative activity and protection provide effectual integrating among several supply concatenation spouses.

An Experiment Transpired Because Of A Fascination With...
This experiment transpired because of a fascination with basketball. In inches, the tested variable was the basketball court surface that gave the basketball the most immense bounce. After testing each surface, the data got averaged out, and based on the statistics, the multi-purpose floor averaged .7 inches more colossal than the hardwood, and 3.7 more than concrete. Introduction ââ¬Å"Playing basketball can be hard work. Players not only have to run around the court, but just dribbling the basketball takes some serious effort, too.â⬠(ââ¬Å"Surface Science: Where Does a Basketball Bounce Best?â⬠). Energy reserved inside the ball, transfers into Different types of energy (ex. Heat, sound) when the ball hits the ground. But, which type of court restores the most energy back into the ball? Wood, multi-purpose, and concrete are the three types of court surfaces being experimented on. ââ¬Å"All professional and collegiate leagues use hardwood court for their basketball games.â⬠(Lorelie). Thereââ¬â¢s logic in why they use them. For example, Wood courts got referred to as one of the softest courts. Concrete surfaces got researched too. ââ¬Å"These are the most popular types of surfaces for outdoor basketball courts. In fact, nearly all who play basketball starts playing on concrete or asphalt court.â⬠(Lorelie). This shows, they must be popular for their spring, and for being compact and durable.
