Chemistry - Essay Example In this conformation there is no steric strain and no torsional strain. Due to the migration of electrons towards the more electronegative nucleus in a bond between two different elements the molecules become polarized. In larger molecules a number of poles form and this causes some parts of the molecule to attract and some to repel each other. In the butane molecule both ends of the molecule are rotating around the C-C bond and take different configurations (these are constantly changing. Steric strain is caused by the crowding together of groups – as explained above the groups are forced to approach each other till they touch, but because of their similar polarity they are under forces of repulsion also. This leads to the molecule possessing extra potential energy, this energy is called steric strain. a. In 1870, Markonikov laid down a basic principle of chemistry that holds till today. The Markonikov Rule states that when a hydrogen halide (Hydrochloric acid, HCl being an example) reacts with an asymmetrically substituted alkene the hydrogen attaches itself to the carbon atom that has the larger number of its hydrogen atoms substituted. The halogen automatically attaches itself to the carbon atom having the least number of its hydrogens substituted. An example of such an addition reaction: b. Enantiomers are two molecules of the same chemical that are the mirror image of each other, like our hands, they are similar but yet not the same and can not be superimposed on each other. Such molecules are called Enantiomers. They are not isomers and are not different from each other in any way except in their configuration. c. An Emperical formula gives the proportion of the constituent elements in the molecule but does not give the exact composition of the molecule. The empirical formula represents the mole fraction/ ratio of each element in the compound. For example the empirical formula may show that there is hydrogen and

MRI - Essay Example Magnetic resonance imaging (MRI) produces detailed images of the body’s internal organs and problems associated with the organs. It is procedure that has typically no side effects and cast images with no fear of pain. The process uses magnetised radio radiations and draws the images when the waves reflect back to the scanner. It is different from the CT scan or CAT scan. An MRI scanner is composed of two donut shaped tubes that are joined by a hollow tunnel that holds a person. The donut shaped tubes produce powerful magnetized radiation. A sliding table holds patients and it slides into the tunnel of the scanner. However, some MRI centres have MRI scanner with larger openings to hold patients that are suffering from claustrophobia. Most hospitals now have MRI scanners; while dedicated MRI centres are also opened for the ease of patients. The MRI scanner generates powerful magnetic waves that interact with the atoms of the patient’s body. During interaction the magnetic waves makes the atoms of body to be in particular pattern. The pattern is observed by the powerful antenna and sent to the computed that draws an image with respect to the observed pattern. Computer converted image both in 2d and 3d formats. The results are viewed by the physician to diagnose the problem. Kindly bring other examination reports like X-ray, Ultra sound, CT scans, Nuclear Medicine Scans or previous MRI scan reports along with you, if you can. This may help the physician to make comparison between the reports. Kindly do not let your child to wear any type of metallic jewellery like chins, hair clips or rings as metals may disrupt the magnetic resonance waves. Check you child carefully before the examination begins. If the child’s physician recommends using dye to clarify the results, be sure that child’s takes nothing by mouth (NBM) several

Headhunters in Personnel Staffing Industry Dissertation

Headhunters in Personnel Staffing Industry - Dissertation Example Some businesses may require few replacements, and thus the cost of entering into such agreements is high when the commission charges are low. Further, signing written agreements to recruit workers with certain qualities comes as a contractual obligation that must be fulfilled. However, there are instances where headhunters may not find the ideal candidates, which puts their competitiveness at risk or risk legal action from employers. Employers also benefit from â€Å"gentlemen’s agreements†. There are instances where headhunters save businesses in dire need of employees. In these situations, the employers need urgent solutions that are easily found through â€Å"gentlemen’s agreements†. Designing and signing of a legal contract would be time wasting for both parties. In normal practice, headhunters may lure employees from competitors. Such actions cannot be easily put in legal terms. Thus, requiring headhunters to sign a written contract is detrimental to the personnel staffing industry.   An agreement between headhunters and businesses should be treated as a legal contract. Headhunters and employers would then be in a binding agreement. In addition, headhunters should clearly outline their charges and the modalities of their operations. Recruiting agencies are crucial in an enabling the meeting of employers and prospecting employees. For example, in the case, Cantell, et al. V. Hill Holliday Connors Cosmopulos, Inc., the recruiter enabled Hill Holiday to meet Nancy Lehrer, whom it employed later. Though there was no signed agreement, headhunters enabled Hill Holiday to secure an employee; thus, they ought to pay a commission since it is the only way recruiters make money (Conklin 25). I believe that the agreement between the plaintiff and the defendant in the case could be strengthened by clear guidelines in regard to the operations of the recruiter. In such a case, an employer can know that it owes headhunters for any communicati on it makes with their referral. Thus, the industry can continue surviving with its current simplicity.

Passenger To Freighter Conversion Of Aircrafts Engineering Essay

Passenger To Freighter Conversion Of Aircrafts Engineering Essay The purpose of the report is to provide detailed description for future aerospace engineers on how and why a P2F (also known as PTF or Passenger-to-Freighter) conversion is carried out. 1.2. Background Ever since the new millennium started, P2F conversions on aircrafts have become more common in the civil aviation industry. Major civil aviation industry companies (Airbus, Boeing, etc.) started researching with designs on how to modify an airframe structure of their ageing passenger jets to cargo freighters. In conjunction with the current economic situation, civil aviation logistic companies are trying to find ways to cut down expenses on replacing older cargo freighter aircrafts- buying P2F converted aircrafts. Furthermore, P2F conversions extend lifespan of passenger jets, providing first-hand quality P2F cargo aircrafts at second-hand cargo freighter prices. Since there is an increase in demand in the cargo freighter industry more companies will look at P2F conversions .Mainly because it is more economical for the company and they can gain the same amount of revenue at the same time. 1.3. Methodology The information was gathered from a few websites through the internet, books and magazine references .The content was retrieved from websites like http://www.eads.com , books like, magazines like. 1.4. Scope The Focused areas are mainly about the structural differences between a freighter aircraft and a passenger aircraft. In addition, the report will include structure of freighter planes. In addition, it will include the pros and cons of P2F and how the conversion is carried out. Lastly, this report includes the technical effects to the aircraft structure. 2. P2F Conversion Procedures There are various types of P2F conversion procedures. The various procedures are basically created by primary manufacturers (Boeing and Airbus) and assorted conversion companies (EADS (European Aeronautic Defence and Space Company) and SIAEC (Singapore International Airlines Engineering Company)).As a result , there are many different procedures for a P2F conversion to be complete. The following procedures will be according to the 4-month conversion of the Airbus A310 wide-bodied airliner into the Airbus A310-200F by Elbe Flugzeugwerke (EFW).In the following few paragraphs I will discuss about the different procedures carried out during a P2F conversion procedure. (SPG Media Limited, 2010. Airbus A310-200F Freighter Aircraft-Aerospace Technology [online]. Available from: http://www.aerospace-technology.com/projects/a310-200f/) 2.1. Preparation before conversion The airplanes paintwork is scraped off. Thereafter, a fraction of the passenger cabin is taken out. The aircraft is then jacked into a neutral stress point for 4 weeks for the modification of the airframe. With the plane partially empty it is jacked up into a neutral stress point for 4 weeks for the adjustment of the aeroplanes body. (SPG Media Limited, 2010. Airbus A310-200F Freighter Aircraft-Aerospace Technology [online]. Available from: http://www.aerospace-technology.com/projects/a310-200f/) 2.2. Plug windows Now that the aircraft does not carry any more passengers, windows in the aircraft are useless. The windows previously used for passengers to look out of the aircraft are now plugged (covered up). As u can see in the image below, there are no more windows in a freighter aircraft because it saves time on maintenance and for safety reasons. Therefore the windows are plugged.(Marcel van Leeuwen, 2006, Boeing 747 Large Cargo Freighter Arrives in Seattle [online]. Civilian aviation news. Available from: http://www.aviationnews.eu/2006/09/17/boeing- 747-large-cargo-freighter-arrives-in-seattle/) Figure 2.6: Plugging of Windows (Airbus Freighter Conversion, 2010) 2.3. Removal of unwanted material Anything in the aircraft that is not needed anymore is removed from the aircraft. Passenger- related facilities and structure (like seats and carpet flooring) is take out of the as it does not come in handy for a cargo freighter. This is to make room for the installation of the new freighter equipment. With the removal of redundant material it creates space for the cargo. (SPG Media Limited, 2010. Airbus A310-200F Freighter Aircraft-Aerospace Technology [online]. Available from: http://www.aerospace-technology.com/projects/a310-200f/) 2.4. Fitting of cargo door The front-end of the fuselage section is opened up in 2 stages for the installation of the cargo door. The upper frame shell is held at its position and is secured by riveting the frame to the fuselage. The old lower frame shell section is substituted with a new lower frame shell that is lowered into the prepared cut-out location and incorporated strongly to the airframe. The frames forward and aft of the cut-out are entirely replaced by reinforced frames. After the installation of the frames, electric components and hydraulic systems are added for the cargo door to operate with ease. (SPG Media Limited, 2010. Airbus A310-200F Freighter Aircraft-Aerospace Technology [online]. Available from: http://www.aerospace- technology.com/projects/a310-200f/) Figure 2.1 à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ Cargo door of Boeing 747-200BDSF http://www.iai.co.il/sip_storage/files/6/34576.wmv, 2002 2.5. Installation of new flooring The normal flooring on a passenger aircraft cannot be used. Hence, the flooring on a passenger plane has to be removed and reinforced with a higher strength floor to resist heavy cargo loads. To move the cargo in the aircraft easily, ball mats and roller tracks are installed onto the cargo flooring. With the new flooring the aircraft can carry more load and be tough at the same time and move the cargo within the aircraft easily.(SPG Media Limited, 2010.

Available from:http://www.aerospace-technology.com/projects/a310-200f/) Figure 2.2-cargo loading system of airbus http://www.eads.com/eads/int/en.html 2.6. Final checks after conversion Once the body of the aircraft has been converted and all thatà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s left to do is to do a final check on the whole aircraft. Firstly, the aircraft avionics is adjusted before tests are carried out. Thereafter, the customer inspects the flight to make sure everything is in working condition. However, before the aircraft is handed over to the customer the documentation for the conversion is finalised. With all these procedures done, the P2F conversion is complete. (SPG Media Limited, 2010. Airbus A310-200F Freighter Aircraft-Aerospace Technology [online]. Available from: http://www.aerospace-technology.com/projects/a310-200f/) 3. P2F conversionà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s cost impact 3.1 Replacement of ageing Freighters by P2Fs. Since the current condition for the economy is not at a very healthy condition, many aero- logistic companies would scout around for second hand cargo freighters. However, second-hand freighters have now reduced in numbers so drastically that most of them will stop flying within a few years. Hence, P2F conversions will help solve the problem of ageing cargo freighters in the near future. In 2009, airbus presented their 20-year forecast of their future freighter fleet. In their statistics shown in Fig3.1, Airbus emphasised on P2F conversions as the way to go to solve the problem of freighter insufficiency Therefore, by 2028 more than half the freighters around the world will be P2F converted. This is because P2F conversion requires low cost, shorter time and less material than manufacturing a freighter from scratch, making it a cost effective solution. (J. Leahy, L. Rouaud, 2009.

Demand of P2F aircrafts P2F conversion will take the freighter industry to a whole different level. In addition, the wider range of freighter types from P2F conversion will create a new generation of small jet freighters (e.g. Airbus A320 P2F).Besides that ,majority of Airbus freighter demand will be aided with P2F conversion as 96% of freighters in 2028 will be P2F aircrafts. This shows that the future of the P2F conversion industry will have a bright future. (J. Leahy, L. Rouaud,2009.

Benefits and limitations of P2F conversion Despite its many advantages such as its ability to save money time, material and manpower needed. Alongside, it helps extend an aircrafts life and replaces ageing freighters in the market. However, its disadvantages include acceptable use of market price as well as availability of aircraft. The next few paragraphs will explain and elaborate more on the benefits and limitations of P2F conversion. 4.1 Benefits 4.1.1 Saves cost Companies around the world who are looking to purchase freighter cargo aircraft would most likely try to save up on anything they can save on. One of the benefits of P2F conversions is that it helps companies save money. A P2F converted aircraft costs nearly one third of a freighter aircraft made from scratch. Since ità ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s just part of the aircraft that is reconstructed, it will help save cost on the amount of material used. When there is less work to be done, less manpower is needed. Hence; they can save cost by employing fewer engineers to work. Therefore, P2F conversions help save money for companies. (According to Phillip Securities Research (2005), initiating coverage Singapore) 4.1.2 Extends aircraft life A P2F conversion helps extend an aircrafts life span as well. When an aircraft is almost reaching its age of retirement it can either be scrapped or reborn again. In this case the aircraft is sent to companies that deal with conversions. The old structure is replaced with new structure in order for it to fly safely. Therefore, P2F conversions help extend the lifespan of an aircraft.(EADS media centre, Rising (like a phoenix [online], available from: http://www.contentforce.de/iptv/player/macros/_s_eads/_x_s- 35848193/mediacenter.html?height=500HYPERLINK http://www.contentforce.de/iptv/player/macros/_s_eads/_x_s- 35848193/mediacenter.html?height=500width=1024attrs=scrolling=noHYPERLINK http://www.contentforce.de/iptv/player/macros/_s_eads/_x_s- 35848193/mediacenter.html?height=500width=1024attrs=scrolling=nowidth=1024HYPERLINK http://www.contentforce.de/iptv/player/macros/_s_eads/_x_s- 35848193/mediacenter.html?height=500width=1024attrs=scrolling=noHYPERLINK http://www.contentforce.de /iptv/player/macros/_s_eads/_x_s- 35848193/mediacenter.html?height=500width=1024attrs=scrolling=noattrs=scrolling%3Dno) (SIA engineering company websiteprovides information on what P2F conversion is) 4.2 Limitations 4.2.1 Acceptable used market price P2F conversions serve as a form of investment for airline companies. If the cost of the conversion is more than the proposed price to sell the aircraft, the owner selling the P2F converted aircraft will incur a loss. In addition, different models of aircraft go through different kinds of conversion processes. Hence, the standard of quality and the workmanship to set prices for the P2F aircrafts vary widely, which might lead to underpriced P2F planes. (Hamilton, http://museair.googlepages.com/ThePassingofanUnrecognisedIndustryGi.pdf , 2007) 4.2.2 Airframe availability In order to perform a P2F conversion, there must be available airframes. The airframe needs to be from an airworthy passenger jet which is not in service anymore. If not, it would make no sense just to make an aircraft and convert it. Therefore, the number of used jets there are out there is limited to availability. (Hamilton, http://museair.googlepages.com/ThePassingofanUnrecognisedIndustryGi.pdf , 2007) 5. Conclusion The P2F conversion procedure may seem simple to digest. However, it is much more sophisticated compared to the other areas in the aeronautical market. Regardless, the freighter market is shinning their spotlight on P2F conversions to give old passenger aircrafts a second chance to fly again as freighters. In addition, P2F aircrafts are able to perform almost as well as new freighters made from scratch. No matter how advanced P2F conversion gets, there are limits for the acceptable used market price. Otherwise, the conversion will result in heavy loss financially. 6. Recommendations P2F conversion is a very profitable market to invest in. Companies dealing with P2F can take one more step by making use of more advanced technology when they are converting aircrafts. It can help save cost by using less material and maybe even with efficiency. Therefore P2F conversions can take one more step ahead by doing more research in this industry as there will be a rise in demand for freighter aircrafts in the future. III.

The Effects Of Stress, Alcohol Outcome Expectancies, Gender, Coping St :: essays research papers

The Effects of Stress, Alcohol Outcome Expectancies, Gender, Coping Styles, and Family Alcoholism on Alcohol Consumption Abstract One large component of American popular culture today is alcohol. A common stereotype for the effects of alcohol is that as a drug it acts as a stress antagonist. This theory was introduced by Conger (1956) as the Tension Reduction Hypothesis (TRW). It states that alcohol's sedative action on the central nervous system serves to reduce tension, and because tension reduction is reinforcing, people drink to escape it (Marlatt & Rehsenow, 1980). Why do we drink, when do we drink, and how much do we drink? This research will determine the correlation between total weekly consumption of alcohol and perceived stress, alcohol outcome expectancies, gender, coping styles, and family history of alcoholism among undergraduate students. Do people drink more or less when stressed? Do alcohol outcome expectancies lead to higher or lower consumption? Is a history of family alcoholism positively or negatively correlated to personal consumption? Do the tested variables play mediating or moderating roles in stress-related drinking? This research will determine the answers to these questions, and determine the strength of the correlations, if any. Introduction The main question that this statistical model will answer is as follows: Is there any correlation between drinking and gender, alcohol expectancies, family alcoholism, stress, and coping styles? Gender It has been demonstrated that significant differences exist between the drinking patterns of men and women (Hilton, 1988). In a survey of US drinking habits conducted in 1988 by the US National Center for Health Statistics, Dawson and Archer (1992) showed that there are three areas illustrating gender differences. The first is the actual number of male and female drinkers. The study showed that 64% of men versus 41% of women were current drinkers. Second, men were more likely to consume alcohol on a daily basis (17.5 grams of ethanol per day versus 8.9 grams for women). Third, men were more likely to be classified as heavy drinkers. In fact, when the classification measure of a "heavy drinker" was changed from five drinks or more per day to nine drinks or more per day the ration of male to female heavy drinkers increased by a factor of 3. Stress Are the theories mentioned above about stress-induced drinking accurate? There have been studies which disprove the Tension Reduction Hypothesis. For instance, in a study by Conway, Vickers, Ward, and Rahe in 1981 it was found that "the consumption of alcohol among Navy officers during periods of high job demands was actually lower than the consumption during low-demand periods." Additionally, some drinkers have been known to consider alcohol as a tension

Microeconomics Market Structures

According to the principles of microeconomics market structures can be identified as perfect competition, oligopoly or monopoly. In our society today and the way business is conducted, market structures are not strictly defined by on of these particular types. They can be composed of a mix of them. A market structure that has a higher level of competition can be more efficient than those that have lower levels of competition. We know this since lower competition increases the producer’s surplus; in return it decreases the consumer surplus.The loss in the consumer’s surplus is means it will be greater than the increase in the producer’s surplus. This leads to what we have learned as a deadweight loss. A perfect competitive market can also be thought as the most efficient form of market, where consumers are the most beneficial. Realistically it is difficult to identify and choose a perfect competitive market. Perfect competitive markets have the following character istics: * No entry or exit barriers: These markets should have their structures set up with no entry or exit barriers.Simply meaning that new suppliers can invest in their company without any significant capitol or risk. They can also exit the industry without facing any significant loss. *Infinite buyers and sellers: the markets have unlimited or infinite amounts of producers that are willing to sell their products to an unlimited or infinite amount of buyers. This is to ensure that there is no supplier or buyer has a significant market share. This is to prevent others in the market from being able to determine the market price. Perfect Information: This is when all competitors in the market have to provide and share equal information among/between each other. Suppliers and buyers alike, go forward and profit from having full and complete information, just like the other suppliers and buyers in the markets. The above conditions benefit consumers as these firms develop and become pr ice takers. The price of the product will be decided by the supply and demand. The equilibrium point is where the supply curve and demand curve intersect and establish the market price of the product.Therefore, in all aspects of business the price is equal to marginal cost. If we look at the short-term affects then there is the possibility for a firm to make a profit. However, this is not the traditional outcome and will quickly attract other firms in the industry. In turn it will elevate the level of supply demands. As a result of this increase, the products price will decrease. Simply meaning that in a perfect competitive market it is not feasible for a firm to profit in a long-term aspect.This doesn’t necessarily mean that a firm will not earn any profits. It means that the profit earned covers all the costs to produce the goods. This can include interest and liability. In turn, the long-term outcome for the firm in a perfect competitive market will earn a normal profit. T he profit will always be significantly less then firms in a monopoly or oligopoly would earn. Capitalism is based on the principles of the free market. In free markets the supply and demand variables help determine the quantity of the goods produced along with its market price.There are many foreign countries and their firms that have tried to implement free markets but have not been very successful because there has never been that type of market in international transactions. This is because global trade and national trade are derived from the same principles. The foundation of international trade is the principle of comparative advantage. Each country has different sets of resources. These variables are different because some countries have large populations, which influence the labor pool, especially when some people have specific developed skills in a one industry.For example, if people in Antarctica wanted to drink coffee that would have to or import them since the climate is not conducive to growing it. If Antarctica decided not to use international trade, they would either have to go without coffee or grow it in an un-natural environment. The cost of growing and providing coffee would increase the market price. Instead since Antarctica participates in international trade, they have the ability to focus and provided coffee to its countries consumers. Simply meaning that countries that have comparative advantages get it from their products for which has the lowest opportunity cost.If these countries focus on products that create their comparative advantages then the total output would be greater for the consumers of the world than if each country tried to individually produce everything. The marginal cost or the cost of producing a new product usually cost less than the average cost of producing a good. This is because the additional production usually is achieved without making any substantial new investments. (V,Kumar, 2008). Globalization allows produ ction to shift to the people and places that are in a position to produce the best products at the most competitive price (V,Kumar, 2008).When the total supply demanded is more, the consumers will benefit since the price will be lower. Simply meaning that in the absence of international trade, consumers around the world ended up having fewer suppliers who could provide the necessary good to produce their products and meet their demands. Ultimately letting the supplier controls the market and its price. If we consider an assignment we have earlier in this class, let us consider the automobile industry of the 1950’s and the present industry. In the 1950’s there were only three companies who produced and sold cars in the United States.Based on what we learned in this class it is defined as an oligopoly. The automobile industry was a highly profitable industry in the 1950’s. When international cars were imported in to the United States, they were competitively price d much lower than the cars produced on home soil, and the imported goods had better quality with more fuel efficiency. In turn consumers quickly shifted their interests and money to the imported vehicles. This caused local producers to be forced to lower their prices and improve their standards in order to stay competitive.International trade brought more options to consumers. It’s providing higher levels of competition and improved quality and efficiency. With free international trade, producers can provide and compete for customers across the world. Consumer surplus is defined as, â€Å"An economic measure of consumer satisfaction, which is calculated by analyzing the difference between what consumers are willing to pay for a good or service relative  to  its  market price. A consumer surplus occurs when the consumer is willing to pay more for a given product than  the current market price† (Investopedia: dictionary).When the number of suppliers in the indust ry increases it leads to higher levels of competition, and these market conditions found in a perfect competitive market end up being more profitable to consumers. Social cost are one of the variables that lack in all studies of economy however, as our society advances, so do social costs and this is reflecting in the markets. We have learned a lot about comparing the cost of a product and revenue generated from it In turn if we take into account the growing effect of social costs and the social benefits that can emerge from this trend.We cannot forget that there are also marginal social costs. The marginal social cost becomes greater with each additional thing that happens that is considered undesirable or also knows as un-anticipated cost activity. For example, an oil company that is drilling must extend its hours on Friday to reach the minimal amount of oil harvested. This will mean there will be a marginal cost for each additional hour the oilrig must operate to reach its quota. Marginal social cost would be the upward slope that shows the cost increasing with each additional output.Marginal benefits would be the opposite as marginal social cost with a downward slope. Environmental factors show the relationship connections between marginal social cost and marginal social benefit. Lets assume that all firms are constantly trying to reduce the level of pollution that they create. This is not an over night process and it does require a significant amount of capitol. This would affect the marginal benefit. Now on a different hand lets assume that a company has been cited for not following the regulations that govern company’s pollution control. This company is now required to get up to code.They are going to have to buy the new equipment that is required. This will inflate company’s costs and may affect the company’s ability to produce their products competitively. This could create many problems for the company but will ensure they are fo llowing required rules. Since it is for the good of society it means that the marginal social cost is beneficial than the marginal social benefit. Proving that marginal social cost and marginal social benefit lines cross where the two are equal. This class have class has taught many aspects and principles of microeconomics.It began with supply and demand and ended with marginal costs and benefits. All of the principles affect local and international firms, as well as consumers that are in both places. These studies will continue to evolve as business and society moves forward in the future.Work Cited * V,Kumar, VK. (2008, July 28). Globalization:who benefits from it.

In the first movie Bella Swan falls in love with a vampire. The vampire, Edward Cullen, is very protective of Bella and tries to keep her safe. In New Moon Edward feels that the only way to protect Bella is to break her heart so she won’t follow him. However after Edward leaves Bella comes face to face with danger and the only protection she has is her long-time friend Jacob who she realizes is a werewolf. By the end of the movie Bella is torn between her love for the werewolf and the vampire. Analysis My focus is on scene nine where Bella is confronted by the Cullen’s vampire rival, LaRon. LaRon’s intent is to kill Bella now that Edward has left her defenseless. The scene is set in the meadow where Edward first appeared to Bella in his true form. When the sunlight shined on Edward his skin glistened like diamonds. At that time the meadow was beautiful, the grass was green, the flowers were in vibrant full bloom, and the sunlight shined down so bright. Now that Edward has left the meadow is dead, the grass has turned brown, all the flowers are gone, and the lighting is low and gloomy. I like to think of this as a metaphor to Bella’s spirit how it was alive and vibrant with Edward’s presence and is now dull and a part of her has died. Also you see her in a dangerous position being face to face with LaRon without Edward being there to protect her like before. Then Jacob appears in the scene in his werewolf form to protect Bella. However at this moment she does not realize it is Jacob. Here we are seeing Jacob in his true form appear to Bella just as Edward did for the first time and in the same location. It almost seems as though Jacob has taken on Edward’s role in Bella’s world. There is one shot where the rest of the wolf pack proceeds on to kill LaRon and Jacob stops and turns his focus to Bella for one moment and then moves on. At this moment Bella is mere feet away from this massive wolf but she stands there and looks back at the creature. The up-close shot of the wolf’s eye as he is gazing at Bella shows her reflection and you can feel his harmless nature. This is where it all came together for me and I thought Bella had pieced together the clues but I wasn’t until two scenes later that she realized it had been Jacob that rescued her. In one still frame the full shot conveyed danger, protection, love, and loss. This was a very well-organized scene and I think it worked well in the movie and added drama and thrill for the audience.
