Analysis of VSauce - Essay Example Creative re-engineering and several developmental phases enables VSauce to incorporate diversified mechanics that have seen them shift the focus from educative and informative channels to more scientific and comprehendible gaming channels and protocols that necessitate the collaborative impact and views and/or technical development from the users and designers in the community. This gives the channels a competitive advantage compared to other sites in that the diversity of the views and generative aspects from the collaborations help the site in development and design of cutting-edge features. Customization of videos in terms of quality and the subject matter, video, gaming, sports and the interactive aspects, offers freedom of exchange and transfer of knowledge. This merits attention as it incorporates the diversity of age, social and cultural background, economic wellness and freedom of choice from the variety which is the functional perspective of websites and their applications ( Brown 8). Vsauce incorporates the education aspect in the provision of digital, clear and chronological scientific motion pictures in the field of science giving the audience/ academic visitor a variety of videos which actualize the theoretical package taught in classroom atmosphere. This aspect diversifies its operations to more of a blog, content and archive site giving convenience to the variety of users/visitors. Also the incorporation accommodates diversified interests of a single visitor by harmonizing and providing multiple solutions in one site unlike other sites that will give specific solution to a specific interest/problem. For instance, introduction of VSauce2 that has five recurring segments to cover unusual knowledge and technology, â€Å"MindBlow†, a segment that covers the inventions that are useful and their significance to the society are not only humorous but touches the collaborative and the educative aspect of the invention part learnt in schools and in h istory. Also the â€Å"FAK† segment for facts and knowledge, which involves trivial questions, acts as a mental developmental program for all ages which gives the site credit in creativity aspects and collaborative ones as the channel’s work is from the users. Creativity is evident in the way VSauce incorporates the diversity of artistic talents from the users and the community in general. The incorporation of different â€Å"phases† of VSauce with time has seen developments in the users’ contribution in realizing the user’s talents and in line with the growth and development goal of the site and giving back to the society. For instance, the ‘BiDiPi’ segment that stands for build it, drive it and play it, incorporates the talents of the communities and the site user/fans and brings the competitive aspect of the site to the users which act as a motivational tool.

Produce a critical analysis of an article on a current economic issue Essay

Produce a critical analysis of an article on a current economic issue of your choice from the 'Financial Time' - Essay Example According to the news, published in the Financial Times on July 13, 2010, Lord Turner who is the chairman of the Financial Services Authority has announced the new proposals for the mortgage lending policy (Goff and Masters. 2010). The FSA has found that due to the shortcoming of the mortgage lending policies, the customer are facing problem with the repayment of the loan that may lead to credit crunch in financial service sector of U.K. The FSA has conducted a review and analysed the current scenario of mortgage market. According to the review, the FSA has found certain facts indicating the borrowers’ inability to repay the loan. These facts have been discusses below. It has been found that the living cost of 46% consumers’ household has been reduced after the repayment of mortgage. The burden of the mortgage repayments are so high that borrowers are left with no or very little money after the repayment of mortgage. The overall idea of FSA’s proposal for the mortgage loan policy is to ensure that every mortgage borrower will be able to repay the loan. Lesley Titcomb, who is a FSA director of the mortgage market has commented that â€Å"While it is clear the mortgage market has worked well for many, we need to build a strong new framework to protect mortgage customers and to ensure that the problems we have seen in the past do not happen again, particularly as the mortgage market recovers† (FSA-website. 2010). However, the current mortgage market is already in distress as there has been a decline in the house prices and the interest rates. â€Å"Estate agents had fewer inquiries from potential homebuyers last month while the supply of homes for sale showed signs of picking up, adding to fears that the housing market could be poised for further price falls† (Cohen. 2010). The supply of the real estate has gone up but the demand for houses remains weak in the first quarter of this month. The agents

Corrosion Pillowing in Aircraft Fuselage Lap Joints Essay Example for Free

Corrosion Pillowing in Aircraft Fuselage Lap Joints Essay Nicholas C. Bellinger,âˆâ€" Jerzy P. Komorowski,†  and Ronald W. Gould†¡ National Research Council Canada, Institute for Aerospace Research, Ottawa, Ontario K1A 0R6, Canada DOI: 10.2514/1.18589 This paper presents the results of studies that have been carried out at the National Research Council Canada on the effect that corrosion pillowing has on the structural integrity of fuselage lap joints. Modeling of corrosion pillowing using ï ¬ nite element techniques showed that the stress near the rivet holes increased to the material (Al 2024T3) yield strength when the corrosion present was above 6% thickness loss. In addition, the analysis showed that pillowing resulted in a stress gradient through the skin thickness, which suggested that semi-elliptical cracks with high aspect ratios could form. During teardowns of service-exposed lap joints, these types of cracks were found at numerous holes and a closer examination of the fracture surfaces revealed the presence of fatigue striations. Therefore, a new source of multisite damage, other than fatigue, was identiï ¬ ed. I. Introduction N THE 1980s, it became apparent that commercial transports would remain in service well beyond their original design life, which raised concerns that corrosion combined with fatigue could lead to catastrophic failures of fuselage lap joints. Although there are multiple lap joint designs present in a single fuselage, for older aircraft the majority of them consist of an outer and inner skin fabricated from aluminum 2024-T3 joined together with multiple rows of countersunk rivets (Fig. 1), as well as an adhesive layer. During the operation of an aircraft, the adhesive layer can deteriorate and disbond allowing moisture to migrate between the skins. This moisture can, in turn, breakdown the material protective system resulting in the formation of crevice corrosion. As the corrosion forms, the skins between the rivets are forced apart due to the presence of the corrosion products resulting in a bulging or â€Å"pillowing† of the skins. This phenomenon is referred to as corrosion pillowing and is the feature used to detect corrosion in lap joints using visual (ï ¬â€šashlight) nondestructive inspection techniques. This paper reviews the results to-date of studies that were carried out to determine the effect that corrosion pillowing has on the structural integrity of fuselage lap joints. The results indicate that corrosion pillowing can cause the formation of semi-elliptical cracks with high aspect ratios, which were found in a number of serviceexposed corroded lap joints. These cracks formed at a number of different rivet holes and thus are considered to be a new source of multisite damage (other than fatigue), which could signiï ¬ cantly affect the residual life and strength of a lap joint.

Therefore, to determine if a correlation existed between the amplitude of the pillowing deformation of the outer skin of a lap joint to the degree of corrosion inside the joint, a mathematical model was developed. This model presumed that after the lap joint disbonds the aircraft skin between the rivets deforms perpendicularly to the lap joint surface to accommodate the additional volume required by the corrosion product. A chemical analysis on corrosion samples taken from service-exposed lap joints indicated that the insoluble product mainly consisted of aluminum oxide trihydrate (aluminum hydroxide), which has a molecular volume ratio of 6.454 times that of pure aluminum [1]. The model assumed that the corrosion product was distributed within the joint so as to exert a uniform lateral pressure on the fuselage skins. It was also assumed that the joint was symmetrical about its midplane and thus only the outer skin was modeled. The closed-form classical plate theory of Timoshenko and Krieger was used to calculate the deformation of the outer skin supported by equidistant rivets and subjected to a uniform lateral pressure [2]. This deformation was used to calculate the pillowing ratio given by the ratio of the central deï ¬â€šection to the volume under the deformed plate [3]. From this model, the central deï ¬â€šection was determined to be approximately 3.3 times the thickness loss for a rivet spacing ratio of one. To better understand the effect that the rivet spacing ratio had on corrosion pillowing, the deformed shapes of plates with various rivet spacing ratios were calculated and the results are plotted in Fig. 2. The results showed that as the rivet spacing increased, the relative deï ¬â€šections at the shorter edges decreased, whereas those at the longer edges increased, which can signiï ¬ cantly reduce the probability of detecting the corrosion visually. This suggests that the detection limit for joints with a high rivet spacing ratio, may be signiï ¬ cantly larger than the maximum allowed 10% thickness loss. B. Stress Analysis Because actual lap joints contain free edges and stiffeners, which cannot be modeled using the closed-form solution, ï ¬ nite element techniques were developed to model an actual aircraft lap joint (Fig. 1). This model included the effects of the hoop stress from the pressurization of the fuselage, the rivet prestress caused by the rivet installation as well as the corrosion pillowing stress. The fuselage curvature was ignored for all the analyses that were performed during this program.

Enzyme Kinetics Laboratory Report

Enzyme Kinetics Laboratory Report How the changes in substrate concentration (PNPP), changes in temperature, changes in pH and the presence of an inhibitor (phosphate ions) effects the rate of reaction of the reaction between PNPP and water catalysed by the enzyme acid phosphates which produces PNP and phosphate as its products . Using spectrophotometer to measure the absorbance of the products formed through hydrolysis of substrate. Abstract: The purpose of this scientific paper was to replicate earlier findings of experiments in enzyme kinetics and to see if enzyme behaviour and activity is influenced by 4 factors- change in substrate concentration, temperature, pH and the presence of a competitive inhibitor. In the first section where the substrate concentration was altered whilst the enzyme concentration was kept constant the relationship was found to be hyperbolic this can be explained using the Michaelis -Menten equation and the Lineweaver burk plot which was also used to obtain Km values of 0.25 and Vmax values of 0.12UNIT. The increase in [S] increased the rate of reaction at first but when [S] too much the initial velocity started to decrease. The increase in temperature led to a general increase in the initial velocity until the temperature reached 347 K where the enzyme denatured. The optimum temperature of the reaction was in the range 310 K- 323.2 where the rate increased at its fastest. The third section was the effect of pH on the enzyme activity. The optimum pH of the reaction was 5.5. This pH gave the highest reading of absorbance which means that the rate of hydrolysis was at its highest. Finally the last section of the experiment was the effect of competitive inhibitor on the rate of reaction. The investigation showed that the inhibitor used (phosphate ions) was a non-competitive inhibitor. The inhibitor did lower the initial velocity of the reaction when it attached to the enzyme at random. Introduction: This laboratory report is on the topic of enzyme kinetics, previous work in this particular field was carried out in the 1700s, when biological catalyst enzymes were discovered and studied. As understanding of enzymes increased scientist carried out basic laboratory experiments such as the conversion of starch to sugar by saliva to increase their understating of enzymes and how they function. However the first actual incident where enzymes were understood in detail was in 1897-by Edward Buchner .Since then on, till this period of time factors which effect the velocity/ rate of reaction and enzymes have been studied widely by many scientists globally. The modern scientists have a deep understanding of enzyme kinetics. The purpose of this laboratory report is to confirm previous findings covered in various sources of scientific literature and journals. Enzymes are often described as organic catalysts which increase the rate of reaction of a bio-chemical reaction ( David L.Nelson etal 2008). Enzymes increase the rate velocity of various reactions that occur in a biological system such as the mammalian digestive system. Enzymes can have functions including transfer, synthesis or breakdown of molecules. It is important to mention that enzymes are proteins which speed up the rate of reaction without being used up themselves i.e. they are reusable. Enzymes have a very specific active site which is complementary to a specific substrate 3 dimensional structure. The specificity is due to the complementary hydrophilic/hydrophobic charge, electrical charge and shape of active site on the enzyme. The binding of an enzyme with an specific substrate produces an enzyme substrate complex (ES).The rate at which the enzyme substrate complex is formed is dramatically increased or decreased in changes in substrate concentration, temperature, pH and presence of an competitive inhibitor the effect of these 4 factors on the enzyme activity is known as enzyme kinetics (Jeremy M. Berg etal 2006).Enzymes work on the concept of transition states. Transition state of enzymes is the phase where the substrate is not a yet a product and not a substrate. Enzymes reduce this phase .The difference between the free energy of the reactants and the free energy of the transition state is the activation energy (Ea).The minimum energy required for a success full reaction to occur. Enzymes speed up the rate of reaction by lowering the activation energy barrier. A typical enzyme substrate reaction can be simplified and be written as: The enzyme studied in this investigation was acid phosphatase. This enzyme can be identified by its Enzyme Commission Number (EC number) which is 3.1.3.2. Now I will briefly discuss the enzyme kinetic properties of acid phosphatase. The enzyme acid phosphatase catalyses the removal of phosphate group from organic molecules. Its primary mechanism of action is to bring a substrate molecule into contact with a molecule of water .This results in catalysis and the removal of phosphate group. Finally an hydroxyl group is attached to the substrate molecule. An example of this is the reaction shown below. This reaction was studied in this laboratory investigation. Acid phosphatase p-nitrophenylphosphate (PNPP) + water phosphate + p-nitrophenol(PNP) In the reaction above PNPP is the synthetic substrate, which is described as chromogenic.At. At high purity this compound is completely colourless. PNPP is hydrolysed by the enzyme acid phosphatase this produces phosphate and PNP. The product produced is yellow and can be measured using a colorimeter. The first part of the investigation concerns the effect of substrate concentration on the rate of reaction. I predict and expect that at an increase in substrate concentration (PNPP) will lead to an increased rate if reaction/initial rate. The reason for this is that an increase in substrate concentration increases the chances of a successful collision occurring between the enzyme and substrate increasing the likelihood of ES complex and product (PNP) formation results in an overall increase rate of reaction. This will produce a fist order reaction on a graph. However it is important to mention that at high substrate concentration the enzyme will be fully saturated this will reduce the rate of reaction as the there are too many substrate than enzymes. On a graph this would show a plateau. The maximum velocity of the reaction or the Vmax would be expected to be close to this region. Therefore I predict to see a hyperbolic relationship on a graph. Section B of this investigation concerns the effect of temperature on the rate of reaction. I would exepcet to find that an increase in temperature would result in an increase in the rate of reaction. The reason for this phenomenon is that as there is increase in kinetic energy being applied to enzymes and substrates it increases the chances of collision occurring so more product (PNP) is formed per unit time. However I also believe that temperatures above 50 -70 degrees Celsius would denature the enzymes active site and the 3 dimensional structures. At this stage the enzyme will not be complementary in shape to the substrate. This would mean that no reaction can be completed so the rate of reaction will decrease. It is important to state that the enzyme is going to have an optimum temperature at which the ES complexes and products are made at the fastest velocity. The increase in temperature increase the amount of molecules which have higher energy than the Ea barrier this in turn increases the amount of molecules which can react increasing the rate of reaction or initial velocity. I believe the optimum temperature is going to range between 20-40 degrees Celsius. The third part of this lab report is based on the effect of pH on the rate of reaction again I believe that at extremes of pH such as acidity or alkalinity will affect the rate of reaction. This may cause the enzymes structure to denature and will cause a lower rate of reaction and lower rate of product formation because the enzyme will not be complementary to the substrate. I would expect this enzyme to have a low optimum pH of around 5-2 as it is acid. Finally the last section of this investigation concerns the effect of a competitive inhibitor (phosphate ions) on the rate of reaction. Inhibitor in this case the phosphate ions will compete with the actual substrate PNPP for the active site of the enzyme acid phosphatase. These inhibitors can only attach to the active site of the enzyme due to their complementary properties. The concentration of the inhibitors will be kept constant and the concentration of the substrate PNPP will be altered. I believe that as the concentration of PNPP increases the rate of reaction will increase this is because the PNPP can out- compete the competitive inhibitor and reverse the effect of the inhibitor. Materials and Methods: All procedures were carried out as described in the lab schedule. No alterations were made to any of the procedures carried out throughout the experiment. Discussion: The first section of this lab report relates the effect of substrate concentration on enzyme activity. I shall briefly discuss and explain what my data shows and means. Graph 3 which is the graph of Michaelis Menten of collected data. The relationship between the rate of an enzyme-catalysed reaction and the substrate concentration can be describes as hyperbolic. The graph and tables 2 show that as the concentration of substrate (PNPP) increases from 0.00 Mmols to 0.20 Mmols of substrate the initial velocity or the rate of reaction shows an increase in too. The relationship can be describes as fist order as the [V] rises almost linearly with the increase in [S]. However after the concentration increase from 0.20- to 3.00 Mmols the initial velocity shows a gradual increase and then gradually levels of or slopes here graph shows 0 order relationship. This supports the prediction I made in the introduction. The graphs indicates that as the concentration of substrate increase the rate of reaction increase this is because of the increase chances of a collision between a substrate and an enzyme. This in turn increases the rate at which ES and P are formed. However after the concentration increase after 0.20 3.00 Mmols the rate stars to level off. The reasoning behind is this is that there are too many substrates than compared to enzymes an all enzymes are described to be fully saturated .At this phase the reaction is at its Maximum velocity and cannot increase in rate unless more enzymes are added therefore enzyme concentration is the limiting factor. I can tell that the data I collected from the experiment in the lab is accurate and valid as the graph which compares the theatrical data and the collected data show similarities in the trend line the Vmax the km and as well as the points and there is no anomalous data point on either of the 3 graphs. My findings support the findings of many previous investigations and journals as the graphs show a similar relationship as to the findings to previous work. The implications of this investigation can be used widely to determine the Vmax and KM. These values can be used for medical purposes since the enzyme acid phosphatase is manufactured by the body to remove phosphate groups. The limitation of Michaels Menten plot is that the Km and Vmax cannot be accurately determined. Therefore a Lineweaver burk plot is plotted. The Lineweaver burk plot shows that the KM and Vmax are very similar to the ones from the Michaelis Menten plot. Finally KM is an approximate measure of the affinity of an enzyme for its substrate.A small value of KM indicates a high affinity of the enzyme for the substrate. From my graphs (1 +2) I can tell that the KM was 0.24 and therefore small. This means that the enzyme acid phosphatase has a high affinity for the synaesthetic substrate PNPP. This means that small concentration of substrate PNPP is enough to run the reaction at half of maximum velocity (1/2 Vmax). The next section of the investigation concerns the effect of temperature on the rate of reaction. I predicted an increase in temperature will increase the rate of reaction or the initial velocity of the e reaction until the enzyme denatures and the protein sequence becomes damaged an unravels. The actual reason for why the protein sequences unravel is that the protein has too much kinetic energy and the amino acids vibrate and this causes the non covalent forces to be weakened. There is an increase in the rate of reaction as the temperature increases from 278 -323 K the increase is almost linear. However after the temperature 323 K-to 347 K the enzyme denatures and unravels. This is proved by the last point on the graph which doesnt fit the line of best fit. Overall the graphs and data all prove my predictions correct. There is no other anomalous data present. The third section concerns the effect of pH on the rate of reaction. As we have discovered before the enzyme used was acid phosphatase so the pH at which it works at best the optimum temperature will be in the acidic pH regions. I can confirm from my graph that the optimum pH of the reaction is in the region 5-5.5 which is indeed acidic. pH of 5.5 gives the highest absorption value, this therefore means that the rate of hydrolysis was at its fastest. A possible explanation for the change in the experimental design is that the pH may denature the enzyme if the enzyme was added first the active site and 3 dimensional shape of the enzyme could be altered at extremes of pH such as 2 which is quite acidic. The pH does not affect the substrates 3 dimensional structure in the same ways as the enzymes. Therefore to obtain valid results /data the design for this part of the experiment was slightly altered. pH has a very strong effect on enzyme activity .This is because enzymes work on the basis of mechanisms such as induced fit hypothesis and lock and key . The enzymes have a specific active site due to the complementary 3 dimensional active site with the substrate. According to the induced fit hypothesis the enzyme can undergo some change in the 3- dimensional structure in order to fit the substrate. However a change in pH changes the enzymes active site structure. An increase in H+ ions can change the active site structure due to the fact that h+ ions can interfere with any polar molecules on enzymes protein structure. Amino acids side chains can be protonated and may be damaged due to the extreme pH (concentration of H+ )this may result in the protein sequence to unravel which means that the active site is not complementary to the substrate and the rate of reaction decreases as no or little ES are formed which results in little products formed. The final section concerns the effect of a competitive inhibitor (phosphate ions) on the rate of reaction. From my graph I can tell that the inhibitor present was an non-competitive inhibitor. I can tell this by looking at the Lineweaver Burk plot where the trend lines cross the 1/Vmax intercept at different values but cross the 1/km intercept at the same values. This means that this type of inhibitor does not affect the KM but does lower the Vmax values. Non competitive inhibitor has the same effect as lowering the total volume of enzyme. This type of inhibition is reversible. It binds to a site away from the enzymes active site it denatures the active site so no other substrates can bind to the active site. This in turn lowers the rate of reaction and the rate at which products are formed. However this type of inhibitor also binds to the enzyme substrate complex I can therefore conclude that the non competitive inhibitor does lower the rate at which the products are formed.

If We Are What We Eat, What Does This Count As? Essay -- Food Health S

References can possibly be made between the modern world of high school and the brutal wilderness of Africa. Walk into any high school, and even a college or two, cafeteria and the similarities are blatantly obvious. Here is where the watering hole can be seen: the very place where members of the tribe or pack congregate everyday to talk, eat, and determine the food chain. There are the lions, the seniors of the school, lounging lazily in the sun and reveling in their greatest accomplishment yet: gaining acceptance into college. Next the elephants make themselves known, juniors loud and looking to prove their worth to the rest of the jungle, showing they are capable of operating the complex system known as high school once the seniors are gone. Sophomores present themselves in the form of the chimpanzees, hanging out in the trees, watching another year and all the commotion around them floating leisurely by. Finally, we see the gazelles, frightened freshmen quivering in anticipat ion and excitement of the next four years of their lives, looking for a safe place to graze the savannas. While these four components of the jungle happen smoothly and seem to take little effort, little thought is given to the primary purpose of the animal’s gathering: the food itself. Food, as a vital and necessary part of any being’s existence, is served to the masses within cafeterias across the nation. For many of these schools and some colleges, the food served is neither of the highest quality, nor the most satisfying available. Across the country, millions of schools every year are serving below average meals which do not meet health standards necessary for growing students, meals which are also dissatisfying to the student in both taste and qua... ... distribution of frozen entrees. Better lunches begin with fresh produce, whole grains, and fruits. By way of these five recommended solutions, surely there can be one valid enough to make precedence for the future and allow a better, healthier America.

My lifelong Hobby

While it is true that hobbies are activities we engage ourselves in during our extra times for personal pleasure and relaxation (Microsoft Encarta, 2006), hobbies are also quite expensive and time-consuming for scores of people and occasions. However, when we do what we enjoy expense will always be a secondary thing: the love for the pastime consumes us and leads us to explore all the facets of our interest.I love to draw, experiment with a variety of the painting medium and make people happy by giving them the fruit of my labors. Since grade school years, people in my grade came to know me as one who spends break time or recess as my opportunity to finish with â€Å"orders† from classmates who asked for artistic letterings of their names. Just what are the nuances of this hobby and how did I develop my output from the time I was a very young school child?My hobby is drawing, painting and acquiring a collection of a variety of drawing and painting materials and guides to help me expand my knowledge of creativity and artistry. This paper attempts to briefly elaborate the three types of drawing, which includes doodling, sketching and coloring that I am usually acquainted of and do during my free hours.II. What is doodling and how does one look like when he/she doodles?Doodling is â€Å"to draw something aimlessly or absent-mindedly, usually while doing something else such as attending a meeting (Microsoft Encarta, 2006) and one of the â€Å"funny† parts that I oftentimes do in the presence of other people.This form of artistic ability is very common. It doesn’t take for one to be artistic in order to doodle; however, no artist probably would ever say they have not spent a time that they did not doodle. Attending a class for example or talking with a friend on the phone are perfect times that I get to doodle.Whenever a class starts to get boring, I would pull out my scratch of paper and ball pen and start to make circles or squares, and usual ly end up later with a very messy job at the tip of my pen. Though seemingly an aimless performance to some, this is actually the time when I develop appetite for details and other times mull over how to either imitate an artistic work, or practice those new skills I have adapted.III. What is sketching and how does it differ with doodling?Sketching is drawing a â€Å"picture done quickly and roughly: a drawing or painting that is done quickly without concern for detail† (Microsoft Encarta, 2006). While doodling is almost like its twin, oftentimes it is not the serious type of this skill. Sketching is more of a prelude of what the work will look like when it is finished. It is like a first layer of the foundational principles of drawing, and a body to the artistic work. It tests your patience also whenever you have difficulty achieving the â€Å"look† you want.IV. What is coloring and why does it matter considerably in an artwork?Coloring is applying color to a sketch o r drawing (Microsoft Encarta, 2006). Even before I start to draw, I already have in mind what medium works best with the type of picture I will sketch. This is most crucial for an artist. Many are great â€Å"drawers† but whose work is buried underneath piles of color. This is one area of the artistic expression that also shows texture and life to a drawing.V. ConclusionWhen I doodle, sketch or color, it spells to me luxury. Time is a fleeting resource and doodling, sketching and coloring are skills that make life less boring and predictable. Friendship is built time and again, because of my skills in drawing.Life is a lot like these three: it cannot be hurried. For an artwork to be certified beautiful, time is of the essence. When we pause to ponder and think about our many options in life, we should also strive not only to stop in the â€Å"doodling† or â€Å"sketching† phase, but rub on the hues on an otherwise drab portrait. Spread over affections on people who matter most in your life, and experience the beauty that emerges from their beings.Reference:1. Microsoft ® Encarta ® 2006.  © 1993-2005 Microsoft Corporation.
