The wire showing its resistance Essay Example for Free

The wire showing its resistance Essay I want to find out how the length of a wire changes the amount of voltage and current flowing though the wire showing its resistance. My prediction for the experiment is that as the length of the wire increases the resistance will also increase and as the wire decreases so will the resistance. I think this will happen because the loose electrons are being transported around the circuit and the wire will provide resistance to these, as it is like passing through a sponge rather than air. And so as there is more wire or sponge to pass through it will take increasingly longer and that is why I predicted that. I will change the length of wire between 20cm and 100cm in intervals of 10cm each of these lengths I will do 3 times at different voltages, which are 0. 3v, 0. 6v and 0. 9v. I think this is important to ensure a reliable average. I will measure the amount of voltage and current passing through the circuit. I will keep the voltage the same through each set of experiments e. g. at 0. 3v I will make sure there is 0. 3v at 20cm and 0. 3v at 100cm by using a variable power pack. I will keep the same wires that link up the circuit so that they have the same resistance for each experiment. I will keep the adjustable wire the same and use the same crocodile clips, voltmeter, ammeter and power pack to ensure a fair test. Doing a preliminary experiment helped me to decide what ammeter and voltmeter to use also what voltage to run through the circuit and how short the wire can get before overheating. It also helped me confirm my prediction. It helped me decide to use a digital voltmeter because it gave more accurate readings. The equiptment I will need Power Pack 5 wires Ammeter 1 metre of wire 2 crocodile clips Voltmeter Diagram Resutls Table and Graph. Length of wire (cm) Ex 1 Current at 0. 3 volts ( ) Ex 2 Current at 0. 6 volts ( ) Ex 3 Current at 0. 9 volts ( ) Ex 1 Actual Voltage (v) Ex 2 Actual Voltage (v) Ex 3 Actual Voltage (v) Length of wire (cm) Ex 1 Current x Actual Voltage ( ) Ex 2 Current x Actual Voltage ( ) Ex 3 Current x Actual Voltage ( ) Conclusion I have found out that the longer a wire the more resistance in that circuit which is exactly the same as my prediction. The trends and patterns are that the longer the wire the smaller the difference in current and resistance. As in experiment 1 the difference in resistance between 10cm and 20cm is 0. 16 but the difference between 90cm and 100cm is just 0. 01. The reason we got these results is because the longer or larger a circuit that the current has to pass through the more resistance there is for the current because the wire provides resistance to the current and the more of that wire the current has to pass through the higher the resistance is going to be. The results arent exactly what I predicted because I thought the graph would be a straight line and not curved, I dont know why this is. Evaluation I think that the experiment went very well and I got the results I predicted and did not have any odd results. My method was probably the best method for carrying out this experiment. I could improve it though by doing each experiment more times and at smaller intervals of wire size e. g. every 5cm. I could make the results more accurate by making sure the voltage was exactly what is meant to be e. g. 0. 6v not 0.605v. I think I have enough data to support my conclusion and the results are reliable however I could make them more reliable by doing each experiment more times. I think to provide more evidence for my idea by doing wires with different widths or thickness to prove that the more for the current to pass through the more the resistance.

Our world is growing! Growing in population that is, but the resources are staying the same. To help with the growing of the population that will be happening in the 21st century, science and agriculture need to work hand-in-hand. They need to stand together to make a break through together, to insure that everyone will have food on their plate. We need to work to have larger yields with the land we have. Some people say that humans need to change their diet, and others say that we should destroy hundreds of acres of wild land. According to Feed Nine Billion website, people feel that the only way things will be improving, is if everyone becomes a vegetarian. But others disagree. The people who think that this is the only way do have a good point. Grains and vegetables do produce so much faster than animal production. Then again, you can’t just assume that everyone will follow, and turn to becoming a vegetarian. Besides think of all the farmers that would be out of a job! These farmers could have been family business, just like a dairy farm that is located outside of our town. R&D dairy farm has been handed down generation after generation. Funding has to become an essential in today’s society for this new advance in technology that will be needed. We aren’t only having problems worrying about feeding the next generation; we should be concerned now. Did you know, that in the last 11 years, six of those years the population has consumed more than what was produced? The Food and Agriculture Organization of the United Nations website, just this year the cereal production has gone up eight percent. Imagine what will be expected in the 21st century. People are demanding more food now, than they ever have. Scientists say that far... ...t too expensive for the farmers. The second step is that broader awareness is required. According to Sarah Alexander, â€Å"different farmers trust different sources, such as vendors, crop consultants, and university extension services.† Farmers are going to need to be open minded to new things, in order to feed the human race. The last step is farmers need the right incentives. Farmers want to know about the good that they are doing. Farmer’s want to know how they are saving the environment, and how they are producing more food, and feeding more people than they were before. If we all work together, feeding the nine will be possible, and even likely. Farmers need to know how much they are needed, for this process and know that new ways of farming will help in the long run. People don’t have to change their diets so everyone can be fed. Together, we can feed the world.

Economic Course Work Essay

The market demand (red line) for oil is highly inelastic, and a large change in price only has a small impact on demand for oil. In essence, you will not drive twice as fast because oil is cheaper, nor can you easily switch from using one type of fuel to another(petrol to diesel) just because its price has changed to be cheaper. The supply of oil is relatively inelastic. This is because investment in the production facilities leads to an increase in supply, but the cost of pumping out the oil is relatively the same (Hillier, 2005). It will cost an oil production facility roughly the same amount to produce at half or full capacity. Maintenance and repairs will only be done if the price of oil is high. In essence, we can say that a small change in the demand and supply curve causes a larger change in the clearing price of oil in Russia. As the cost if oil goes up, the Bus fares will increase as transporters will try to recover the remaining cost from the passenger, thus reducing the demand for buses. This in turn will lead to passengers demanding more of the train services which are not affected by the rise in oil price, thus the shift in the demand curve to the right. Indicating a demand for trains. During world the demand for oil was low, thus the downward shift of the demand curve from D1 to D2. This was a result of consumers looking for alternative sources of fuel energy, since the price for oil was high. Also during the recess, due to the recession, the price of oil went up, thus the upward shift of the supply curve from S1 to S2. The high prices led to more production, thus more supply to capitalize on the prevailing high market prices of oil. iv) Use a demand and supply diagram to show what happens to oil prices when the UK adopts energy efficiency measures and invests in wind and solar energy There will be less demand for oil from the British as they will look for alternative means for energy, thus the downward shift of the demand curve from D1 to D2. Thus further development in alternative energy resources means that there is spread of technology thus the equivalent point shifts to the left. v) What happens to oil prices if high economic growth continues in India and China. India and china are following the traditional economic growth path which requires huge oil production and use. Since the national resources are limited, large scale of imports are necessary. Larger demands, higher price, higher expectation to prices attracts speculators to buy more of the oil, which creates the bubble, higher prices of oil due to increased demand (Copeland et al, 2005). 2. Use demand and supply analysis consider what factors on the demand side and which on the supply side will influence oil prices over the next few years? (50 marks) Prospects in the world economy. The world populations is increasing daily, signaling an increase in the demand for oil to meet some of the basic life energy needs . It is estimated that the population of India and China will grow by 8. 4% and 10% respectively. This alone is a big market (demand) for oil (Market Avenue, 2008). Thus this will affect the price of oil, as the demand will increase, thus a rise in the price of oil. Technological development. The world oil supply will improve with new technologies being propagated everyday to ensure more but efficient production and distribution of oil to the markets. This will lead to more efficient and environmentally friendly oil facilities that will increase the supply of oil at a global level (Market Avenue, 2008). As a result, the price of oil will go up in proportion to the investments put in place to do the renovations and maintenances of the oil production facilities. Global economic political situation as with Iran nuclear issue, in as much as Iran has high reserves oil and gas, it is has a nuclear development programme that is looking at using nuclear technology as an alternative to oil and gas. This has prompted political debates impasse, and sanctions as regards the future of energy resources in the world. Reports by Market Avenue (2008) shows that this affects the price of oil in the sense that Iran has the second largest oil reservoir, next to Saudi Arabia, and thus have a greater control over how their international relations plays out with the world super powers and the OPEC to regulate the supply and price of oil. According to Biswajit et al (2007), alternatives to oil, there are increasing alternatives to oil as a source of energy. Many other alternatives like, solar, propane, nuclear energy, bio diesel, hydrogen, battery and ethanol. All these are alternatives to oil that have been proven to work. Even though their use is still small scale compared to oil, they are emerging as good alternatives oil use. This affects the future of oil use globally as they tend to be more environmentally friendly and cheaper than oil. 3. Describe the structure of the world motor car industry (25 marks) The first producer of a petrol engine driven car was Karl Benz, 1885 Mannheim Germany. Over the years many inventions and different models of cars have come. These include brand names such as Toyota, Hyundai, Range Rovers, Mercedes Benz, Nissan just to mention a few. Globally there are many producers of cars. For ease of reference they have been ranked by country. In the top ten we have China, Japan, USA, Germany, South Korea, Brazil, India, Spain, France, and Mexico respectively. The top ten brand names include Toyota, General Motors, Volkswagen, Ford, Hyundai, PSA, Honda, Nissan, Fiat and Suzuki. This is relation to the number if volumes of vehicles the produced in 2009. Depending on the regions, various cars manufacturers have a specific share in the markets in which they operate in. Example is that Thailand is today, already the second largest globally, pick-up truck market after the U. S. and is ASEAN’s largest automotive market and assembler. In her report, Global Automobile Industry: Changing with Times , Chithra Gopal R. S. , M. Sc (Agri), says that in Thailand today all leading Japanese car producers as well as BMW, Mercedes Benz, General Motors, Ford, Volvo and Peugeot assemble cars along with their legions of suppliers. The country has become the main production base for auto- mobile exports in South East Asia. One of the biggest foreign producers located in Thailand is Toyota with a production totaling more than 300,000 vehicles a year and the number is having an upward trend. General Motors (GM), although a much smaller player in Thailand than Toyota, is also increasing production. The other big auto companies located in Thailand are Isuzu, Mitsubishi, Nissan, Auto Alliance, Honda etc. In recent years, BMW and Daimler Chrysler (Mercedes-Benz) have also increased their investments to gain complete control on local manufacturing and marketing operations, indicating that the auto mobile industry in Thailand has the structure of perfect competition (Biswajit et al. 2007).

The hospitality industry can market themselves in social media and networking thus it can be use social media to engage customers and clients in dialogue and recognize their needs & wants. Through these networking sites, hospitality industry could interact with new & loyal guests before, during, and after of the guest staying experience. Social media is relatively new and the advantages are abundance such as it is affordable (no cost), it is viral and has the potential to spread brand awareness rapidly and far and it is said to be able to develop link baits, attention and massive amounts of webpage traffic flow. The purpose of this study is to evaluate Impact of Internet & Online Community  Networking Application (Web 2. 0 internet Technology) based on Budget Hotel in Klang Valley Introduction Hospitality industry play significant role in the world in terms of the numbers of employees and its effect on the community and economical development of a region or country. Hospitality means providing service to others, as well as demonstrating consistent excellence and quality. It should also mean profitably providing value at any price level, while demonstrating your own unique points of distinction. Most of all, hospitality should be a â€Å"place†, where people can still be exceptional individuals and they can extend their own personality and style (Hogan, 2008). The use of internet & networking application for basic functions for instance conferences, business meetings in distant places, training, designed routes and airlines, reservations and tickets purchased through computer systems, tourist shops, restaurants is becoming typical in hospitality industry. The hotels depend progressively on the resources of new information technology to follow and update the tools which allow an efficient development of activities in each section of the company, leading to better results for its management (Mendes-Filho & Ramos, 2003a). To Phillips and Moutinho (1998), information technology (IT) is one of the critical factors of success in the hotel industry. The debate over â€Å"high-tech† or â€Å"high-touch† is largely a thing of the past in the hospitality industry as emerging technologies drive unprecedented change in the way hotels operate and serve customers. It is clear that investments in technologies can generate greatly improved operating efficiencies, higher hotel revenues and enhanced guest services. The pace of change, however, has been so extreme as to leave many hotel organizations uncertain about what types of technology to adopt and the best ways to create a seamless integration of systems company-wide. In addition, investments made by many hotel owners and operators during the last five years have lagged as a result of the serious downturn weathered by the industry. Many hotel organizations are using technologies so outdated as to place their companies at a competitive disadvantage in the marketplace. (dchosenone, Jun 2009) The arrival of the Internet has increased the opportunities to boost the accommodation industry. Recently, hoteliers are fully aware of the benefits that the Internet can calaborate to their business. Well-informed of the far reaching importance of the web, they are motivated to create more awareness of their industry, on top of getting more bookings online. This had driven website development for hotels and resorts, the online reservation booking system, the increased number of reviews and redesigning of accommodation websites, as well as other tourism related online enterprises. As a matter of fact, there is a steady, daily growth of the web strategies for hotel and hospitality. The IT trends in the accommodation industry improve every day. Online marketing renewed the hospitality industry. Social bookmarking, mobile marketing (Runritz application), Web 2. online communities and all others have all added up to the change in the impact of the hospitality industry. The traditional booking system of hotels and resorts has been changed by the Internet. Thus potential guests can easily compare several hotel rooms & facilities and its rates offered by various hoteliers. Then there is the advancement of computer graphics and web photos that hoteliers had utilize to display their hotels’ pictures. In this way potential guests can take a virtual tour to feel the interiors and exteriors of their hotels and resorts. It has also become simple for clients to acquire info on hotels’ Rooms and Rates, amenities, facilities and promos. The emergence of Web 2. 0, allows one with unlimited amount of things the individual can do on the internet these days. The individual is not just restricted to emails or passively absorbing the static information that is available on the web pages when browsing. It used to be one-way but now the web is the platform where people can share information, hold a decent dialogue, build both social and business connections. Social media has recently been adopted by a small group of organizations’ integrated marketing plans. There by infusing a mix of advertisement, public relations, their sales promotion to produce a customer focused message. With the evolution of platforms such as LinkedIn, Facebook, Twitter and YouTube, we have the golden opportunity for exceptional access to the guest (Lanz, Fischhof, & Lee, 2010). Since social media is so available to anyone with an internet connection, it should be a platform that can be recommended to the ospitality industry to increase their brand awareness and facilitate direct feedback from their customers. A business that understands the advantage of social media is well aware that social media is essential in developing new business in the current competitive and online driven marketplace. Marketing is an important aspect for any company involved in business. As such, it is a competitive world out there, and social media marketing is the ‘new kid in town’ and it can reach out to the people accessing these social media platform regularly. Communication is essential for any corporation and business, therefore either they change the way information is conveyed or be prepared to lose some of the audience. It is imperative for marketing managers to continuously find a solution to appeal, keep new and current consumers (Schneider, 2009). Social network is the ideal platform for communication that applies perfectly with marketing in the virtual world. Social networks are groups of individuals who 3 prefer to communicate with one another through a preferred site based on the profile created for themselves (Laudon and Traver, 2007).

Essay about RECRUITMENT SELECTION

Essay about RECRUITMENT SELECTION Essay about RECRUITMENT SELECTION-RESUME MY CV/RESUME Content of the Resume This section explains and identifies the importance contained in all the necessary information to help you prepare a curriculum vitae, (also known as a CV, a resume or personal data sheet).It also helps the employer or Human Resources Manager to have a brief idea and background on candidates, in terms of skills, qualification and experience to match the specific job. Each heading provides the type of content to include, the language to employ, together with examples. NB. It is unnecessary to put CV or any of the other names at the top of the document as it should be very clearly recognised for what it is! 1. Personal details 2. Job objective 3. Education 4.Job experience 5. References 1. Personal details The purpose of giving personal details is to make it as easy as possible for a company to contact you at the right place and the right time! Do not put a heading on this section. Name. First name first, last name last. It is common practice in English It is not common to write your last name using all capital letters. However, each part of your name should begin with a capital letter. If you are from a non-Western country or if you are sending your resume to a non-Western country, it might be difficult for the reader to know what your last name is. In this case you could indicate it by using capitals. There is sometimes confusion between first names associated with a particular gender. E.g. Lawrence in French. Be aware of this. Date of Birth is very important, virtual information to the Human Resources manager for selecting a successful candidate. Today in many countries including Papua New Guinea, people for instance using the same name like; Sam (jnr) named after his father or uncle can be able to use his father’s qualification to obtain employment. With the date of birth on the resume the Human Resources manager can justify by comparing the appearance of the candidate with the date of birth. Place of Origin. Here in Papua New Guinea we have almost 800 different types of language, cultural beliefs and attitude towards work. Where you originate will also be important in the process of selecting the right kind of person for the job and also gives the Human resources manager a fair idea of the applicant. Marital Status.this is common and important in every organization to know the candidates marital status in order to provide benefits for the employee and also the employment may require a single candidate which may require the candidates to work late hours etc.. Religion. Many organizations look forward to employee god fearing candidates which perform the job with trust and honesty because of rapid development in our country and other countries as well.Example;stealing(break and enter etc..) Recruitment officers refer to Religion on your resume depending on the job description, where work is required during the weekend with respect to church. Address Give permanent (or home address) and for instance;IBS campus (or local/temporary address) addresses. For the campus address indicate the last day you will be on campus so the employer knows exactly where and when he/she can contact you. It is also important for you to include your address on the resume to indicate where you reside. Telephone number. It is important to include your phone numbers either, land line or your personal cell phone number. You can also include a close relative members number in case the employer can not reach you, and the country code - PNG is 675 - so the employer can contact you easily if a employment arise in other countries or to further discuss you details. You do not need to put in the first 0 in your telephone number as when one calls from abroad it is not necessary. Include your e-mail address also. Personal Interest The purpose and important of this section is to allow you, once again, to show

Definition and Discussion

Definition and Discussion Lexical meaning  refers to the  sense (or meaning) of a word  (or lexeme)  as it appears in a dictionary. Also known as semantic meaning, denotative meaning, and central meaning. Contrast with grammatical meaning  (or structural meaning). The branch of linguistics thats concerned with the study of lexical meaning is called lexical semantics. Examples and Observations There is no necessary congruity between the structural and lexical meanings of a word. We can observe a congruity of these meanings, for example, in the word cat, where both structural and lexical meaning refer to an object. But often the structural and lexical meanings of a word act in different or even diametrically opposite directions. For example, the structural meaning of protection refers to an object, while its lexical meaning refers to a process; and conversely, the structural meaning of (to) cage refers to a process, while its lexical meaning refers to an object. The tension between structural and lexical meanings I call the antinomy between grammar and the lexicon... The essential aspect of the interrelation between structural and lexical meanings is that lexical meanings constrain grammatical rules. Yet, in stating the laws of grammar we must abstract from the lexical constraints on the rules of grammar of individual languages. The laws of grammar cannot be stated in terms of the lexical constraints on the rules of grammar of individual languages. These requirements are captured in the following law: Law of Autonomy of Grammar From the Lexicon The meaning of the structure of a word or a sentence is independent of the meanings of the lexical signs that instantiate this structure. (Sebastian Shaumyan, Signs, Mind, and Reality. John Benjamins, 2006) The Sense Enumeration Model The most orthodox model of lexical meaning is the monomorphic, sense enumeration model, according to which all the different possible meanings of a single lexical item are listed in the lexicon as part of the lexical entry for the item. Each sense in the lexical entry for a word is fully specified. On such a view, most words are ambiguous. This account is the simplest conceptually, and it is the standard way dictionaries are put together. From the perspective of a typed theory, this view posits many types for each word, one for each sense. . . . While conceptually simple, this approach fails to explain how some senses are intuitively related to each other and some are not. . . . Words or, perhaps more accurately, word occurrences that have closely related senses are logically polysemous, while those that do not receive the label accidentally polysemous or simply homonymous. . . . Bank is a classic example of an accidentally polysemous word . . .. On the other hand, lunch, bill, and city are classified as logically polysemous. (Nicholas Asher,  Lexical Meaning in Context: A Web of Words. Cambridge University Press, 2011) The Encyclopedic View Some, though by no means all, semanticists have proposed that lexical meanings are encyclopedic in character (Haiman 1980; Langacker 1987).  The encyclopedic view of  lexical meaning is  that there is no sharp dividing line between that part of a words meaning which is strictly linguistic (the dictionary view of lexical meaning) and that part which is nonlinguistic knowledge about the concept. While this dividing line is difficult to maintain, it is clear that some semantic properties are more central to a words meaning than others, particularly those properties that apply to (almost) all and only the instances of the kind, which are intrinsic to the kind, and which are conventional knowledge of (almost) all of the speech community (Langacker 1987: 158-161). (William Croft, Lexical and Grammatical Meaning.  Morphologie / Morphology, ed. by  Geert Booij et al.  Ã‚  Walter de Gruyter,  2000) The Lighter Side of Lexical Meaning Special Agent Seeley Booth: Im glad that you apologized to the Canadian. Im proud of you, Bones. Dr. Temperance Bones Brennan: I didnt apologize. Special Agent Seeley Booth: I thought . . .. Dr. Temperance Bones Brennan: The word apology derives from the Ancient Greek apologia, which means a speech in defense. When I defended what I said to him, you told me that wasnt a real apology. Special Agent Seeley Booth: Why dont you think of a word that means you feel bad for making someone else feel bad? Dr. Temperance Bones Brennan: Contrite. Special Agent Seeley Booth: Ah! Dr. Temperance Bones Brennan: From the Latin contritus meaning crushed by a sense of sin. Special Agent Seeley Booth: There. Thats it. Contrite. Okay, Im happy that you contrited to the Canadian.

The Right Prepositions for Geographical Designations

The Right Prepositions for Geographical Designations The Right Prepositions for Geographical Designations The Right Prepositions for Geographical Designations By Mark Nichol The idiomatic idiosyncrasies among references to one’s relationship to geographical or topographical features make selecting the correct preposition a challenge for nonnative speakers, but even those born to English can stumble. This post discusses various classes of phrasing about location. One lives in a town or city, county, state, or nation but on a continent. One writes of one’s residence in a neighborhood or district, but a reference to a side of a city (Chicago’s North Side or New York City’s East Side, for example) is oriented with on. If one lives virtually or literally in the shadow of an imposing natural or artificial edifice, however, one might say that one lives beneath Telegraph Hill or works under the Gateway Arch. If one is referring to some point past one’s current location or another reference point, one might say that the place in question is, for example, below Broadway, even though no change in altitude is involved. In topographical contexts, the preposition depends on the position: One lives in the foothills or in the mountains, even though, presumably, one is not a cave dweller, or in a canyon or valley. But one lives, or stands, on the hillside or mountainside or on the hilltop or the mountaintop or on the valley floor. These distinctions apply to proper names, too: One vacations in the Catskills or backpacks in the Rockies, but one stands on Spyglass Hill (though one can either hike on or up it). One drives on or along a street, road, or highway, but one takes a turn at an intersection or exits at (or onto) an off-ramp. â€Å"In the sea† and â€Å"under the sea† refer to being or traveling beneath the surface of the ocean. However, on, just as on land, is the correct preposition for references to surface travel, though one might also refer to coursing along or over a sea route. One also moves on, along, or over a lake or another body of water, although on also applies to one’s position in reference to a coast, shoreline, or bank, as when visiting friends who live on the ocean, staying at a campsite on a lake, or having a house on a river.
