BaCkGRound While many conventional treatments have been used to remedy chronic joint pain, interest continues to grow in the area of alternative, natural treatments. Eggshell membrane (EM) supplementation is a novel treatment for joint health, and has recently been shown to rapidly and continually improve joint pain in patients with osteoarthritis and joint and connective tissue disorders. The current study aimed to observe the effects of one particular eggshell membrane product (fast joint care+; FJC+) supplementation on chronic joint pain in physically active adults. METhodS Sixty adults (40. 2  ± 10. 2 y; 78. 6  ± 10. 2 kg) experiencing chronic joint pain supplemented daily with either 500mg FJC+ or placebo, over the course of 4 weeks. Participants also completed a weekly exercise protocol designed to challenge their irritated joint. Participants then rated their joint pain immediately, and one day after, this exercise challenge. RESulTS Participants in the FJC+ group reported significantly less joint pain post-exercise following FJC+ supplementation (-16. 13  ± 3. 60) when compared to those in the placebo group (–4. 30  ± 2. 84; p=0. 00171). In addition, during the 4 week study, both groups experienced decreases in next day joint pain (p=0. 0015), although there were no significant differences between the two groups (p>0. 05). ConCluSionS In the current study, daily FJC+ supplementation appeared to decrease post-exercise joint pain vs. placebo, although this effect did not persist 24 hours post-exercise. Because eggshell membrane research is in its infancy, further research may be needed to clarify its utility in managing joint pain. 1 Precision Nutrition | www. precisionnutrition. com BaCkGRound Why Study Eggshell Membrane? n the united States, over 20% of adults have reported doctor-diagnosed joint and connective tissue (JCT) disorders; this number has been projected to increase by 40% over the next 25 years [1, 2]. numerous forms of intervention have been used as treatments to improve joint pain. Conventionally, nonsteroidal antiinflammatory drugs (nSaids) and analgesics have been used to address joint pain associa ted with JCT disorders; however, their long term use has been associated with diverse and severe side effects including cardiac and gastrointestinal complications [3, 4]. Alternative therapies used to treat joint pain include dietary supplements; the most popular of these supplements being glucosamine, chondroitin and methylsulfonylmethane (MSM). While many turn to these complementary treatments to avoid the side effects associated with NSAIDs and analgesics, there is little evidence to support their effectiveness, and the evidence that does exist is equivocal [5]. Several large-scale human clinical trials [6], including the National Institutes of Health-sponsored Glucosamine/Chondroitin Arthritis Intervention Trial, as well as a few additional meta-analyses and reviews [5, 7] have reported limited effectiveness of glucosamine and chondroitin supplementation in reducing joint pain. However, other groups have noted long-term improvements in joint pain from glucosamine supplementation alone [8], and further enhanced effectiveness of combined glucosamine sulfate and chondroitin sulfate, rather than the separate use of either supplement [5, 9]. The question of their effectiveness in JCT populations is subject to ongoing debate. There has been growing interest in eggshell membrane (EM) supplementation as a treatment for joint pain, as it does not present the side effects of conventional treatments (NSAIDs). Eggshells and their membranes have been extensively analyzed 2 Eggshell Membrane Reduces Joint Pain for their components: the separate layers of the eggshell have been analyzed and found to contain several types of collagen (types X, I, V) [10-12]. Additionally, EM has been found to have notably high concentrations of a number of amino acids [13], collagenlike proteins [14-16], enzymes [17-19] and glycosminoglycans (GAGs). Glycosaminoglycans are of high interest, as they play key roles in connective tissue [20]. Glucosamine, hyaluronic acid and chondritin sulfate are important GAGs in EM (21, 22). With the high protein and enzyme content, and naturally occurring GAGs in EM, scientists and nutritional supplement companies have speculated that it could present a viable alternative to traditional joint disorder and osteoarthritis treatments. Additionally, while the aforementioned elements of EM have been detected, it should be noted that membrane components have not yet been wholly characterized; there are likely a number of compounds that have yet to be identified in the membrane. Some of these yet undetected elements may contribute to benefits or improvements seen in joint health. To date, very few studies have investigated the effects of EM supplementation on joint pain and range of motion. In rats, 4 weeks of EM treatment led to significant reductions in many proinflammatory cytokines (measured in plasma), notably including TNF-? nd IL-1 [23]. Two recent clinical reports [24, 25] investigated the timing and effectiveness of EM supplementation in JCT and osteoarthritis patients experiencing severe pain and limited range of motion. These patients received daily 500mg doses of oral EM for four to eight weeks. Rapid (seven to ten days) and continuous effects were seen in terms of reduced pain and stiffness, as well as im proved flexibility. In both investigations, there were no reports of adverse effects with supplementation. In the present study, we set out to observe the effects of EM (fast joint care+; FJC+) supplementation on joint pain within a physically active adult population experiencing chronic joint pain in one of four joints (ankle, knee, shoulder or elbow). As many adults use exercise to manage joint and connective tissue disorders, this population would likely see great benefit from adjunct therapies designed to reduce pain and increase range of motion. 3 Precision Nutrition | www. precisionnutrition. com METhodS What We Did. And How We Did It. Prior to commencing the study, all participants gave their informed consent. A total of 60 adults between the ages of 18 and 70 (45 men and 15 women; 40. 2  ± 10. 2 y; 78. 6  ± 10. 2 kg; see Table 1) agreed to participate. Each reported chronic pain in one of the following joints: elbow, shoulder, ankle or knee. Participants were recruited online through a popular health and fitness community and data were collected through self reports in a distance-based capacity. Participants were also prescreened to exclude those who had used any additional medications (methotrexate or immunosuppressants), NSAIDs, analgesics, or joint supplements (MSM, glucosamine or chondroitin) two weeks prior to the start of the study. Those with egg allergies, or who were pregnant or breastfeeding, were also excluded. Participants were asked to refrain from use of pain medications throughout the study period.

In order to participate, individuals had to be exercising regularly, at least three times per week. They were screened for their regular physical activity (reported 4. 8  ± 1. 1 exercise sessions/wk), and asked to ensure that both their exercise and nutritional regimens remained unchanged over the course of the study. After matching for age, sex, and affected joint, participants (n=60) were randomly assigned to receive either the EM supplement (fast joint care+; FJC+), or a placebo supplement for 4 weeks. These groups did not differ significantly in terms of age or weight, contained similar numbers of men and women, and contained similar numbers of individuals with shoulder, elbow, knee, and ankle pain (see Table 1). All supplements were provided to subjects in identically marked containers, and all capsules (placebo and FJC+) were identical in appearance (color, flavor, size). All participants were instructed to take their â€Å"supplement† once per day, at the same time of day (i. e. first thing in the morning, with breakfast). 4 Eggshell Membrane Reduces Joint Pain Each capsule of the FJC+ supplement contained 500mg of Gallus gallus (chicken) eggshell membrane extract (a commercial preparation sold as fast joint care+ by Genuine Health, Toronto, Ontario); additional non-medical ingredients included rice flour, magnesium stearate, gelatin, and water. The color and flavor matched placebo capsules contained only rice flour, magnesium stearate, gelatin, and water. The individual components of FJC+ were not quantified in the supplement as the product is intended to be used as a complete eggshell membrane extract, without additional ingredients (ie. additional glucosamine, chondroitin, etc. . In addition to their normal exercise program, participants were asked to complete an additional exercise challenge once per week. This exercise challenge was to be completed on the same day of each week (Monday) and at the same time of day (in the morning, after supplementation and breakfast). The exercise challenge for those with chronic shoulder or elbow pain consisted of pushups. For those with chronic knee or ankle pain, the exercise challenge consisted of jump squats. Each of these sessions involved performing 10 sets of 5 repetitions of the given movement, with 2 minutes of rest between sets. Immediately after each exercise challenge session, participants rated their specific joint pain on a Visual Analog Scale (VAS) at two time points: within 10 minutes of completing the challenge and 24 hours following the challenge. Compliance to the exercise programming and supplementation schedule was self-reported and logged by participants; those logs were provided to researchers weekly via email. Subjects were also asked to report any side effects during the trial. Joint pain was assessed using a 100mm visual analog scale (VAS), and participants submitted this information via electronic form. A self-assessment was performed at the two time points (post-exercise, and next day after exercise) for each of the 4 weeks. Each subject was asked to â€Å"click on the line below to indicate how severe the pain is on the affected joint with 0 being no pain and 100 being pain as bad as it can be†. Responses were submitted electronically on a weekly basis, after each pair of assessments. VAS scores were then measured in millimeters from the left hand end of the scale to the point marked by the subject. Data were collected across the 4 weeks of supplementation, and analyzed using a two-way ANOVA with repeated measures (i. . MANOVA). In cases of significant interactions (p? 0. 05) post-hoc analysis was performed using Student’s t-test for comparison between groups, and paired t-test for comparison within groups (JMP, SAS Institute Inc. , Cary, NC). The VAS ratings were reported on a scale of 0 to 100, with 0 indicating no pain, and 100 representing greatest pain. Where ap propriate, change scores were examined after adjusting absolute scores and then comparing between groups with a one-way analysis. All values are reported as mean  ± SEM, and statistical significance was set at p? 0. 5. To summarize the protocol in brief: During week 1 of the investigation, subjects took their first 500mg dose of FJC+ with breakfast on Monday. After breakfast they immediately performed their first exercise challenge and then rated their joint pain using the VAS described above. In addition, they rated their joint pain on Tuesday, 24h later. During each subsequent week, subjects repeated the same protocol, providing 4 weeks’ worth of joint pain data, with week 1 serving as a baseline. 5 Precision Nutrition | www. precisionnutrition. com RESulTS So What Happened? Following 4 weeks of supplementation, participants in the FJC+ group had a significantly greater decrease in post-exercise joint pain compared to participants in the placebo group (-16. 13  ± 3. 60 in the FJC+ group and –4. 30  ± 2. 84 in the placebo group; p=0. 0171; see Figure 1). Figure 2 illustrates changes in joint pain between groups across the 4 weeks of supplementation: main effects were found for both time (p=0. 0003) and the interaction between group and time (p=0. 0354). 0 Change in Joint Pain Index (VAS) -5 Placebo FJC+ -10 -15 -20 * -25 Figure 1.

Post-exercise joint pain (measured with VAS) across 4 weeks of supplementation. There was a main effect for time (p=0. 0003), and an interaction between time and group (p=0. 354), indicating greater joint pain decreases in the FJC+ group (-43. 4%) than the placebo group (-30. 6%). Post-hoc analysis showed between group differences from week 1 to week 4 (p=0. 0171). Note: higher VAS values indicate more pain. In accordance with Figure 1, post-exercise joint pain in the FJC+ group decreased by 43. 4% while the placebo group experienced a 30. 6% decrease in pain over the 4 week period. Post-hoc analysis shows a mean difference between groups when comparing overall change in pain from week 1 to week 4 (p=0. 0171). Next day reports of joint pain also decreased over time (p=0. 015; see Figure 3) with next day joint pain decreasing by 46. 7% in the FJC+ group (from 35. 34  ± 4. 33 during week 1 to 18. 82  ± 4. 38 during week 4) and by 40. 9% in the placebo group (from 26. 38  ± 4. 58 during week 1 to 15. 59  ± 4. 01 during week 4). There were no significant differences between the groups’ joint pain scores across the 4 weeks of supplementation (p=0. 1971 for group and time interaction). 7 Precision Nutrition | www. precisionnutrition. com 50 Joint Pain Index (VAS) 40 30 20 10 0 1 2 Weeks 3 4 FJC+ Placebo Figure 3.

However, there were no significant differences between groups across the 4 weeks (p>0. 05), indicating similar joint pain decreases in both the FJC+ group (-46. 7%) and the placebo group (-40. 9%). Note: higher VAS values indicate more pain. Participants in both placebo and FJC+ supplementation groups did not report any side effects during the study. 8 Eggshell Membrane Reduces Joint Pain diSCuSSion Some Clarifications About Our Work The results of this investigation suggest that four weeks of supplementation with 500mg fJC+ daily improves post-exercise joint pain vs. upplementation with placebo, specifically in physically active adults experiencing pain in the ankles, knees, shoulders, and elbows. Other investigations using EM supplementation have observed similar reductions in joint pain, specifically in populations with osteoarthritis and JCT disorders. In one randomized, double-blind, placebo-controlled study, daily oral administrat ion of either 500mg placebo or 500mg EM was given to patients with knee osteoarthritis [24]. After 10 days, rapid improvements in both joint pain and stiffness were seen in the EM group. Improvements in pain and stiffness were sustained (and enhanced) following 60 days of administration. A similar study with JCT patients [25] also observed both rapid (7 days) and sustained (30 days) improvements in pain and flexibility following daily administration of 500mg EM. There were no adverse events reported in either study, and the treatments appeared to be well tolerated by the patients. These statistically and clinically significant outcomes suggest that EM supplementation may be a natural and effective alternative therapy for both clinical populations with limited activity levels as well as physically active populations. Many of the various components present in EM have been thoroughly analyzed. Eggshells consist of a number of layers: an inner and outer membrane, a mammillary layer (connecting the eggshell and outer membrane), an outer palisade layer, and an outer cuticle covering the eggshell [10]. The inner and outer shell membranes are the first layers of extracellular matrix covering the egg itself [11]; the outer membrane is predominantly made of type I collagen, whereas the inner membrane consists mainly of type V collagen [12]. In addition, type X collagen has been reported to occur in both of these membrane structures [10]. EM amino acid profiles have also shown high concentrations of arginine, glutamic acid, histidine, cystine and proline [13]. Additionally, a number of collagen-like proteins (including hydroxyproline, hydroxylysine, desmosine, and isodesmosine) are primary structural components of the membranes. 9 Precision Nutrition | www. precisionnutrition. com Other components have been quantified in EM including: lysyl oxidase (reported to play a role in the development and repair of connective tissue), ovotransferrin, and lysozyme [17-19]. However, the presence of glycosaminoglycans in EM is of particular interest. Glycosaminoglycans (GAGs), such as glucosamine, are composed of repeating hexosamine disasccharides and act as major components of connective tissue [20]. Clearly, there are a number of individual components present in the EM that have known physiological roles in joint and connective tissue; however, EM is novel in that it is a natural extract that provides a combined source of these compounds. The absolute quantity of each component in the EM is not known, and those quantities may likely vary with each extraction in the supplement production process. Additionally, it is plausible that a number of yet unisolated elements, proteins, and enzymes exist in EM, which may also contribute to improved joint and connective tissue health. Therefore, the observed benefits associated with EM supplementation may not be directly attributable to any one specific component of the supplement (ie. lucosamine, chondroitin, etc. ); it may be more appropriate to assume that the combined effects of the known—and unknown—components of EM contribute to the observed improvements in joint health. A number of individual components in EM are known to have important roles in maintaining connective tissue in vivo, though the physiological mechanisms by which those components improve overall joint health through supplementation (flexibility, connective tissue repair and maintenance) have no t been measured in humans. One experiment, however, investigated the effects of EM supplementation on systemic pro- and anti-inflammatory markers in rats [23]. In this study, rats were given oral doses of EM for 7 days. Significant decreases were observed in plasma levels of numerous inflammatory antigens following supplementation; thus, it is possible that the anti-inflammatory effects of oral EM supplements may contribute to the improvements in joint pain ratings seen in human trials. More research is warranted to investigate these effects. Interestingly, the most pronounced effects of FJC+ supplementation in this study were present in post-exercise ratings of joint pain. This may be due to the proposed anti-inflammatory benefits associated with EM. If the exercise challenge used in this investigation led to acute joint inflammation, it stands to reason that the most pronounced impact of EM would be to reduce the pain associated with this postexercise increase in inflammation.

Additive Layer Manufacturing for Aerospace Parts Essay

ES Technology has revealed that additive layer manufacturing (ALM) for direct part production has been embraced by a number of manufacturing sectors, not least the aerospace industry The ability to produce components in a range of materials including hot-work steels, stainless steel, cobalt chromes and Inconel, plus titanium and aluminium alloys, presents the aerospace industry with large potential for direct part production using ALM. ALM has already been used to produce small and medium-sized aerospace components, and having realised the potential of the process, aerospace manufacturers are seeking to produce larger, more complex parts. Material Solutions operates an ALM applications development centre with a particular focus on the aerospace sector. Carl Brancher of Material Solutions, said: ‘ALM in high-performance materials is well suited for complex thin-walled structures in gas turbines. ‘However, as a new technology it is not yet well understood or validated by potential users and, like all manufacturing processes, to get the best from metal ALM requires the designer to understand the process capabilities and materials’ mechanical properties,’ he added. Brancher said Materials Solutions is bridging this gap by providing manufactured parts, consulting (principally to the aerospace market), and working with equipment and materials vendors to develop the technology for mass production. See more:Â  Masters of Satire: John Dryden and Jonathan Swift Essay The collaboration between Material Solutions and its industry clients has so far led to the production of a range of components over the last three years. This programme has now reached the limit of component size that can be produced using the existing Material Solutions ALM systems. With the continuing pressure from aerospace manufacturers to develop the capability to produce larger parts, Material Solutions turned to Concept Laser to explore the potential for building larger components using Concept Laser’s M3 linear system. The fundamental principles of the M3 linear make it a novel development in the world of ALM. Unlike other machines the M3 linear does not have fixed optics but a combination of galvo scanning mirrors and linear direct drives to move the scanning head. Already used to build larger volume components, the M3 linear has all of the pre-requisites for up-scaling to enable production of the types of components envisaged by the aerospace industry. It is not only the physical attributes of the system that lend themselves to production of large components but the process control and laser scanning strategy already developed by Concept Laser, which will eliminate the potential pitfalls of accuracy errors on large components. Having established the potential of the M3 linear machine, Material Solutions set out to design a test component that would qualify certain build criteria and which could also be used to educate and inform aerospace designers of ‘Additive Friendly’ design features and techniques. These include reducing supports and using larger flowing radii to assist in reducing the time to build and subsequently, component production and finishing costs. The test part incorporates many features such as small diameter holes, threaded features, thin rib sections and areas of thick material section all typically found in aerospace components. The greatest challenges for Concept Laser were that a component of this size had never before been built and added to this the part was required in an unexpectedly short timescale. The finished component demonstrates the current capabilities of the technology in terms of size (300mm diameter), accuracy and surface finish. While this part does not yet satisfy the ultimate demands of aerospace manufacturers it clearly confirms the capabilities of the process, the scalable potential of Concept Laser’s M3 linear machine and the sound base which Concept Laser have for further development of the M3 linear for large aerospace components. There are also practical aspects to be considered when building large parts. Larger volume components require greater volumes of powder and hence a robust and stable platform to accommodate the weight. Having then built a large volume, and potentially very heavy component, safe and easy removal is essential. The M3 linear machine is built around a substantial fabricated framework and already incorporates a removable build module enabling the module and component to be easily positioned under an overhead crane if required. The success of this exercise and the current collaboration between Material Solutions and Concept Laser will be used to define the future strategies that will eventually see parts manufactured by ALM techniques leave the laboratory and take to the air.

Why Could Be Considered a Turning Point in Lord of the Flies

Filippo Denti! 07/04/2009 Explain why Chapter 4 could be considered a turning point in Lord of the Flies Chapter 4 can be considered a turning point in the book since it shows many different aspects of the book which weren't covered yet. It starts showing the savageness of the children and the loss of civilisation and order. it also shows that with all this anarchy the children still have order in their souls whom they can not expel. the chapter also tells us how people ignore commands and follow a person just because they are afraid of him. Chapter one ? ts perfectly well in the beginning of the book.The chapter gives us a clear vision of what has happened before the beginning of the book; the plane crash, the atomic bomb; the island and the war. It shows it when Ralph, then known as the boy with fair hair says that; â€Å"This is an island. At least I think it’s an island. There is a reef out in the sea. Perhaps there aren’t any grownups anywhere. † we ? nd out it’s a plane crash when Piggy says â€Å"There was that pilot. But he wasn’t in the passenger tube, he was in the cabin in front†. As the book goes on Ralph and Piggy ? nd all of the other boys on the island and the choir, with its boss Jack.Thanks to Ralph the children are united under a shell, the Conch, this precious shell is the symbol of legacy, order and respect. The children join together thanks to the Conch, since Ralph blew in it and it made a very high sound which was heard by everybody. When all of the children were gathered a leader was elected and that http://listverse. com/wp-content/ leader was Ralph, partly because he was the biggest and partly uploads/ 2007/08/6a00d41432c15a685e because he was handsome. The most important event in these 00d41436fd406a47-500pi. jpg chapters, in my opinion, is the ? re. The ? e was created so that the ships and airplanes that passed could see the smoke and notice them. The idea of the ? re is great but you should never joke with ? re and the result of their ? re was that part of the island was burned and a poor child got killed. Out of this mess Piggy is showing up as being the most intelligent and intuitive of the group. Chapter four starts off with a description of Jack painting his face. This is very important because it shows the changement of Jack into a beast. He is painting his face to be scarier and, in his thinking to appear as a warrior. This comes from ! 1 Filippo Denti! 07/04/2009 ncient African tribes who used to paint their faces to scare the prey. This is a very important symbolical event, it starts showing the transformation of the boys, from civilised to savages. The intent of jack is to scare, scare like a savage the wild beasts, the new people of their new world, beasts who have no laws and do what they want when they want it. This is shown when Jack is convincing Bill to leave the ? re: â€Å"The rest are making a line. Come on! † â€Å"But- -we-† â€Å"Co me on! I’ll creep up and stab-†. This is why the ? re went out while they were hunting. He is forcing people whom are following a set of rules to go savage and kill boars.This is the moving into the wild. Bill is afraid of what the others would think if he didn’t join, they would have thought that he was a person who was afraid of breaking the rules. This is bringing people into the wild. Jack paints his face showing that he is a warrior. A warrior is a person who isn’t afraid of dying and killing. A savage person, who utilises weapons to kill for food. This is the job of the choir and of Jack. They tried to hunt before but with no success since Jack didn’t manage to kill the pig but he promised himself that the next time he will kill it. â€Å"you didn’t kill. â€Å"But I shall! Next time! I’ve got to get a barb on this spear! We wounded a pig and the spear fell out. If we could only make barbs-† Jack is accusing the spear for him not killing a pig but even if it had a barb he didn’t have the guts of killing it. No we see him all http://img101. imageshack. us/img101/8682/ painted in the face willing to kill and involving many lotf2xd6. jpg different people in the hunt, not only the warriors but also the ones of the ? re. This time Jack is willing to kill, â€Å"I’ll creep up and stab† Roger and Maurice, in this chapter, have changed immensely, they, at ? st, destroyed the sand castles in the Littluns play area. Roger was ? rst and came marching in kicking the castles down while going to swim after ? nishing their ? re duty. Roger led the way destroying castles, burying ? owers and Maurice joined after; â€Å"Roger and Maurice came out of the forest. They were relieved from the ? re and had come down for a swim. Roger led the way straight through the castles, kicking them over, burying the ? owers, scattering the chosen stones. Maurice followed, laughing, and then added to the destru ction. †. These two boys are taking advantage that they are bigger and start to bully the Littluns.Roger, after destroying the castles, throws stones to Henry. He throws them without hitting him, as though there was a shield around him. This is because he is turning savage but at an extent, there is still a little piece of civilisation and humanity in their souls. This piece of humanity can not be expelled since it is engraved in their souls. Maurice went away because he had problems before and so he left Ralph; â€Å"†¦ Maurice hurried away. In his other life Maurice had received chastisement for ? lling a younger eye with sand. †. This shows that they haven’t quit with the old habits. ! 2 Filippo Denti! 7/04/2009 When Jack kills the pig the ? re goes out. The ? re is the symbol of hope and rescue, a rescue who could have been near with the ship’s sight. On the other hand the pig represents savageness and the wild. The fact that when the pig dyes the ? re goes out is that savageness covers hope. The children have become savages and went to kill the pig ignoring their only hope signal, the ? re. It’s like a peace ? ame which goes out when a war starts, these two things are opposite and can not cope with each other. The same is in the book, Mr. Golding wants to show that when savageness over? ws through people there is no more order, the order that ruled with Ralph. Ralph ordered that the ? re should never run out, but when Jack decided to go hunting every one went, becoming savages, pigs enemies. The only to be still obedient are Piggy, Simon, Maurice and Ralph, all the rest went hunting, ignoring the orders given. We can se the difference when the hunters come back chanting savage songs: â€Å"Kill the pig. http://www. globalnerdy. com/wordpress/wpcontent/uploads/2008/10/lord_of_the_? ies. jpg Cut her throat. Spill her blood† and when Jack says laughing: â€Å"There was lashings of blood, you should have seen it! . All of the hunters are laughing and singing while the others are still. Ralph continues to say: â€Å"You let the ? re out. †. Only at the end the hunters realise that they could have been rescued and jack apologises: â€Å"I’m sorry about the ? re, I mean. There. I – I apologise. †. Jack has restarted treating Piggy badly, but this time it’s not only the verbal but this time also violence. He, at ? rst, hits Piggy in the stomach and then when he is lying on the ? oor he slaps him making his glasses ? y and break. â€Å"He took a step, and able at last to hit someone, stuck ifs ? t into Piggy’s stomach Piggy sat down with a grunt. Jack stood over him. His voice was vicious with humiliation. †. This shows that he was showing off what he could do, in fact Ralph repeatedly tells him: â€Å"That was a dirty trick. †. Simon is the only one who helps Piggy, he gets his glasses before anyone does something to them. He seems to have changed side, no more Jack Meridew but Ralph and Piggy. Although he seems so mite he continuously disappears into the forest to secret places: â€Å"I painted my face- I stole up. Now you eat- all of you- and I-†. This creates a long silence while he goes in the forest.At the end we see the children eating the meat half raw, this means that they now, not only act but eat as savages, with the food half cooked. This is typical of animals to eat raw ? esh, not of civilised children. The beginning shows the rhythms of the island, the dawn, the dusk, the cool moments and the way the children have adapted themselves. At the end it shows that the children have lost their civilisation. At the beginning we focus only on Jack and the scene is calm, at the end it’s a chaos between the pig and the ? re. Golding shows us the how sudden the changes are. As I red through the chapter I could ! 3 Filippo Denti!

1/8/99 Essay Lord of The FliesThree major themes in this story were: fear, the need for civilization, and instinct to be a follower. The most obvious of all the themes is mans need for civilization. The total opposite of the belief that man is innocent and society is evil is displayed in the story by showing that laws and rules, schools and policemen are all important to keep the dark side of human nature in line. When these concepts are ignored or slip away then we go back to the earliest part of their nature. An example of this is when the boys on the island get together at the beginning of the story and try to set some rules and assign a leader. This does not work out the way Ralph had expected, and it shows that uncivilization may occur when there are no regulations, and guidance from a leader. Fear of the unknown on the island are in the minds of the boys because of the terror of the beast. The fear is allowed to grow because they play with the idea of it. They cannot accept the belief of the beast, and they also cannot let go of it. The recognition that no real beast exists, that there is only the power of fear, is one of the deepest meanings of the story. I someone believes that another is superior, usually in strength and intelligence, they will be a follower of that person and fulfill their wishes. At first in the book, Ralph was elected chief. Everyone followed Ralphs commands because he was the superior. Ralph was Jacks superior, but Jack was still in charge of the members that left Ralph. Jack did not believe that Ralph was his superior in strength and intelligence. He left with choir, who followed him. The others soon believed Jack was superior to Ralph because he could hunt and supply them with food. They, of course, went and became part of Jacks tribe. Thsi all shows that people are easily fooled by a show of superior ability and will follow anyone that they believe to be powerful. Three symbols used in this novel are: the conch,the boys, and the hunting rituals. The conch stands for order and stability. It was a way of getting everyone together for meetings, and showing respect to whomever was speaking while holding the conch. The boys themselves represent the different ways of life, they had the intellectual Piggy, the adventurer, the bully, and the torturer. These all give the impression of diversity that is found in an actual society. the several hunting rituals symbolize the increasing powers of evil in them. All of the chanting and dancing they did when hunting was taken to another level of satisfaction, and excitement of that in murderers. Simon symbolizes the prophet-like figure. He is intelligent, and sensible, and he keeps up the hope that the boys will get rescued even when Ralph is doubting it. Some of the other boys on the island find him strange and think that theres something wrong with him. Simon meets the Lord of the Flies, which is represented by the pig skull on the stick. He is the only boy who realizes that there is no real beast on the island, and the only beast is the boys themselves. Simon is killed by the other boys who were caught up in a savage dance, which was an event that represented their barbaric way of living.

Even though it is a little bit difficult to understand the movie, it has managed what very many directors are yearning for; the ability to leave the audience in need of more and continues with the talk about the movies weeks after watching it. There are creative camera works that has be en used in the development of the movie and this is what contributes to the peculiarity of the movie. For instance, when Leonardo and his partner Arthur visited Saito with their proposal for a dream to steal, the camera work involved in the scene is one of the very rare uses of 180 degrees.

In this case, t he close up shots works to pass important information to the audience and about the character of the individuals as well as what they think.
