Water is the basis of life Essay Example

Water is the basis of life Essay Water is the basis of life, without it life would not have started and would not exist. There are so many reasons for which water is of paramount importance in biology. Water is vital for many processes that are essential for life; it acts as a solvent and as a medium for living organisms.Water is essential for all organisms because it acts as a solvent and medium in diffusion, a reagent for hydrolysis. It is a support for aquatic organisms; life was first created in the sea so this is very important.Importance in all organismsWater is important in temperature regulation in most organisms. It has a high specific heat capacity so it requires a lot of energy to increase its temperature and it retains heat relatively well. This is so that the body temperature does not vary that much; this also means that the temperature of water that aquatic organisms live in will stay at a suitable level. Water can cool by evaporation as it speeds up energy loss as heat, for example by sweating in anim als and cooling transpiring leaves in plants. The high latent heat of vaporisation of water means that the body can be cooled with minimal loss of water.Water acts a transport medium for polar solutes; it is used in movement of minerals to lakes and seas, removal of metabolic wastes such as urea and transport via blood and lymph.Water volatility is suited to the Earths temperatures so that the water cycle of evaporation, transpiration and precipitation is maintained.Water is a medium for dispersal; it can be used to disperse the larval stages of some terrestrial organisms. It is the medium in which sperm are transferred in mosses and ferns. Osmotic pressure helps disperse the seeds of the squirting cucumber.Water expands on freezing, this make ice less dense than water so it floats on top of ponds and lakes, providing insulation to organisms in the water belowImportance in plantsWater is essential in osmosis, as it requires the movement of water from a region of lower concentration to a region of lower concentration of water molecules. The weak hydrogen bonds mean that the water molecules can move relatively easily. One of the reasons that this is important is for water to enter cells by osmosis causing the cytoplasm and that it is needed for turgidity of cells to support the plant. The cohesive forces between water molecules mean that it is not easily compressed so it is a great medium for support.Water is required (it is the reagent) in the photosynthesis reaction, which is also essential as it is the way it produced energy needed to live.Hydroskeletons are a type of skeleton found in many soft-bodied invertebrates, which consists of water-filled body cavities controlled by muscles. Hydroskeletons are found in echinoderms (starfish, sea urchins), annelids (earthworms), nematodes, and a number of other wormlike invertebrate phyla.Water is transparent so make photosynthesis possible in shallow aquatic environments.Without water there would be no plants and the refore no animals either as animalsImportance in animalsWater is a major component of tissues and is an important part of the diet. Most substances in the body dissolve in water. Blood, which is used for transport of substances around the body, is made up of mostly water, which shows how important it is to animals.Water is the medium in which metabolic reactions take place; molecules in solution can move around water and take part in reactions in the presence of enzymes. All chemical reactions take place in an aqueous medium.Water is essential in diffusion across surfaces such as the lungs and alimentary canal.Water is also needed in animals for osmoregulation: the control of the levels of water and mineral salts in the blood.Water is used hydrolyse macromolecules to their subunits, for example in digestion, such as breaking down proteins into amino acids, fast into fatty acids and glycerol, etc.Tears contain water, which is protection against bacteria by killing it and as does mucu s by trapping it.Water can help in lubrication in:- Mucus: lubricates passage of food, colon easy passage for faeces, penis and vagina during intercourse, used externally in some animals such as snails and earthworms to aid movement- Synovial fluid: lubricates vertebrate joints- Pleural fluid: minimizes friction between lungs and ribs during breathing- Perivisceral fluid: lubricates movement of internal organs, e.g. in peristalsis- Pericardial fluid: lubricates movement in heartWater is in amniotic fluid, which protects and supports the fetus of mammals.Water is important in secretions, most secretions include substances in aqueous solutions such as tears, digestive juices and snake venoms.The humours of the eye, both aqueous and vitreous are made up of mostly water; it helps maintain the shape of the eye because it is not easily compressed which makes it useful in supporting.

5 Tips for Writing a Winning Resume - Proofread My Paper

5 Tips for Writing a Winning Resume - Proofread My Paper 5 Tips for Writing a Winning Resume Recruiters may take as little as six seconds to make a decision about a resume. With the job market increasingly competitive, ensuring your resume is well written and correctly formatted is, therefore, essential. But how do you do this? There’s no catch-all method for writing a winning resume. But there are some things to keep in mind†¦ 1. Content The exact content of your resume will depend on your background, experience, and the role you’re applying for. But should always include: Contact Information – Your name, address, email and phone number Job Objective – A brief statement about the kind of role you’re after and the skills you can bring to it Education – Relevant information about college courses and training Work Experience – Details of previous positions you’ve held Skills – Any abilities you have that are related to the job Activities and Achievements – Anything else that could enhance your application (e.g., college societies, volunteering, awards, etc.) 2. Tailor Your Resume to the Job Most roles require particular skills, so you should always tailor your resume to the position. As well as using the job description, try checking the companys website; they may have additional information relevant to your application. It’s fine if you have a basic â€Å"template† with all the important information on it, but make sure you adjust it accordingly before sending it to employers. The mistake this guy made was writing in Latin. [Photo: Flazingo Photos] 3. Two Pages Maximum! Recruiters sometimes have to read dozens of resumes in a day, so they won’t be impressed if yours is a novel-length treatise on your skills as a worker. Try keeping your resume down to a maximum of two pages. If this involves cutting information not directly relevant to your application, do it. Additional detail can be provided in a cover letter. It may be worth noting that, although resume and CV are often used interchangeably, a CV is usually a longer document that includes complete details of your professional experience. 4. Pay Attention to Formatting Since a good resume will be easy to read and visually impactful, it’s worth considering the formatting you use on yours. Minimally, you should use a consistent style throughout, making sure that text isn’t too small to read and that you provide clear headings indicating important details. You may also want to use bullet points to list responsibilities and achievements. Like so. [Image: Dawakhuu/Wikimedia] 5. References Unless a company specifically asks for references (i.e., people who can vouch for your skills as a worker) during the initial application, it’s usually enough to write â€Å"References available upon request† on your resume. And don’t forget: It’s polite to let your referees know if a prospective employer might be calling!

Results, Figures, & Discussion Rubric - Essay Example The experiment was able to justify the hypothesis that sought to establish the brand of towel that is the better water absorber. In this regard, the results were able to deduce that the paper towels absorbed water at different rates. Qualitative results were done through observation of the paper towels over a period of time once they were dipped in water. In this regard, the most absorbent paper towel became more visible and easier to see through it. Furthermore, the paper towels were subjected to the sense of touch by gently feeling touching the towels with the fingers and assessing the level of sponginess and mushiness of each. On the other hand, qualitative results was collected through individual weight measures of the paper towels before soaking them in water and after soaking them in water. The actual amount of water absorbed by the paper towels was achieved through subtracting the weight of the soaked paper towels from the weight of the paper towel before absorption. Repetitio n of the experiment six times assisted in the reduction of data errors. The average amount of water absorbed for the premium paper towels was 20mL. The average amount of water absorbed for the recycled premium paper towels was 15mL. The reason for the difference absorption rates can better be explained by the variance in the production quality of each paper towel. In this regard, the recycled premium paper towels are of a lower quality compared to the premium paper towels. In conclusion, the experiment has justified the hypothesis by showing that paper towels have different capacity to absorb

I knew that, in order to be competitive in the job market, I had to study in an institution that had adequate facilities. Although there are many local colleges I could have

Employment in America Essay Example for Free

Employment in America Essay The United States is amongst the global states which are embracing low rates of unemployment. Except for the Latin America which is fiercely allied to high informal employment the rest of the American continent is having a low unemployment rate which goes as low as 3% compared to 55-60% for most Asian and African countries. Broadly, the effects of law rate of unemployment in the US can be allied to the interaction phenomena in both the macroeconomic and microeconomic structures which have acted to influence the broad array of the economic growth. The state of the economy is stable with few challenges into the inhibitors of poor states of economy. Over decade of years, US have enjoyed the superiority context into a stable state of the economy with elsewhere high purchasing power of the American dollar. Across the global imagery, it has enjoyed various economic benefits and economic integrations of its stable state of economy and strong purchasing power of its currency. High state of economic activity have been the launching pad and the benchmark into high capital inflows from other states through foreign investment in America and the economies allied to favorable balance of payments enjoyed by the America. From the favorability in the economic structures, America has continued to embrace the economic structures of a macroeconomic capacity which provide instruments for high rates of employment. For states within the Latin American region, the high rate of informal employment is much functional and beneficiary with even better wages than most formal employments in the developing countries. Broadly, the high rate of employment/low rate of unemployment in American can summarily be explained by the operation interlinkage between various macroeconomic and microeconomic structures. However, the great deal behind this situation can be credited to the macroeconomic variables which are captured in the broad economic equation. Elsewhere, the fiscal and monitory variables in the functional outlay of the American system provides an adequate pursuit for moral sense of high rates of employment. (Riggs, 2004) At one level, microeconomic variables lobby in to define the factors at an individual level which influence and determine the state of employment. This is mostly credited to the reciprocating factors in the relationship between household income and the levels of consumption and savings. Generally, the economic model of personal income is described as a function of consumption and saving. The relative changes to one another gives the respective marginal propensities (to consume and save). The two are reciprocals of one another where a decrease in one will increase the other. However, within America, the individual population has high marginal propensity to save due to the high income obtained from the formal employment and informal cases. With high saving ratios, the population is able to finance investment cost for new investment structure. The general investment portfolio within the US is highly favorable and highly growing to shoulder in the relatively high employment requirements. High investment structures provide an adequate room with which the broader human population is able to be absorbed within the employment structures. (Riggs, 2004) Macroeconomic influences provide a great refuge for creating employment opportunities. Such macroeconomic tools can be defined in terms of the economic environment to yield adequate economic conditions for a high rate of employment. Generally, the fiscal economic variable does a lot to provide adequate environment for ensuring high state of economic activity. Generally, the federal government has done a lot about its spending to the public. High government spending has been a benchmark in the foundations of high states of economic activity which does not compromise high employment rates. Government spending has been of a diverse nature in which it has provided various insurance allowances to the unemployed above other social structures allied to the public population. Government spending has helped to increase the broad income supply within the public. High expenditure has been an instrument in to the provision of capital for investment by the people. Elsewhere, the federal government has been in the forefront in instituting various structures aimed at providing adequate environment in its investment in government investment. Fiscal policy has also been promoted by various adequate systems in its taxing structure. Consequently, the taxing system has provided a comprehensive package of desirable rate of taxes which are less prone driving out investors from the economy due to losses through government taxation. Through adequate levels of taxes which include tax exemption and rebates for various persons within the economy, the people and investment bodies have embraced the value consequence allied to such law rates of taxes. (Riggs, 2004) Within the America, the monitory policy does a lot in providing an adequate environment for high rates of employment and the reduction of various unemployment inequalities borne of the people. The strong sense of the monitory policy provides a structure with which capital inflow is available. Indeed, America is amongst the global states in which case capital inflow is subordinately of high scale and encompassing no monitory rigidities. Broadly, the American monitory policy can be described in terms of the state of money supply and the demand for American dollar. However, the two sides (both the demand and the supply conditions) show a concrete rigidity in their equilibrium level. The state of money supply is equal to the relative demand which helps to provide an attractive state of equilibrium. With equilibrium in the money market, the American dollar has embraced a high state of purchasing power. Economically, such high purchasing power has been the backbone of facilitating high capital inflows within the states. High purchasing power has provided economic advantage in the international symmetry of economic integrations. Through favorable conditions of economic integrations, America has embraced high capital inflows from its trading partners. (Riggs, 2004) Alternatively a positive challenge into the monitoring system has been a solid factor for the influence of a positive balance of payment. Economically, desirable conditions and states of the monetary marketing are discretionally importance factors in determining the state of employment. Every high employment is an in depended variable of the state of monitory policies. Conceptually, stable monetary economy defines the stability in the economic integration and the parameters of balance of payments. A stable economy is discretionary important for providing structures aimed at improving the state of employment. For every essence of capital inflow within America, this has been a foundation aimed at improving the export level and decreasing the state of foreign imports. Every aspect of high exports than imports helps to improve the state of employment. To America, the low rates of unemployment are counter factors determined by the existing state of high export than imports. Stability in the economic state and the purchasing power of the currency has helped to improve the state of capital inflow within America High capital investment from the foreign world which has helped to improve the existing state of employment states. Summarily, the low state of unemployment in America can be allied to the prevailing economic structures existing within the American economy. The same has favored the stable state of investment which has on the other hand helped to increase the rate of employment within the state.

The Context and Contents of Priscianus of Lydias Solutionum ad Chosroem :: Philosophy Philosophical Essays

The Context and Contents of Priscianus of Lydia's Solutionum ad Chosroem ABSTRACT: Priscianus of Lydia’s Solutionum ad Chosroem is a series of answers to questions asked at a philosophical debate held at the Sasanian court c. 530 CE. Priscianus of Lydia was one of seven non-Christian philosophers from the Byzantine Empire who journeyed to the Sasanian Empire to take part in the debate. Long overlooked in the history of philosophy, Priscianus of Lydia’s text represents a branch of Neoplatonism that survived for centuries uninfluenced by the official Christianization of the Roman Empire. Priscianus of Lydia was one of the last remaining representatives of non-Christian Neoplatonism in Late Antiquity. Solutionum ad Chosroem provides a record of the world of Neoplatonism shortly before it disappeared under a tide of officially Christian philosophy and theology. I discusses the context of Priscianus’ work and its relation to activities in the Byzantine Empire, such as Emperor Justinian’s suppression of paganism and the closing of th e Academy in Athens in 529 CE. I also discuss the specific contents of the Solutionum ad Chosroem, including questions on first principles, generation, natural history, and the relationship between the soul and the body. The Neoplatonic philosopher Priscianus of Lydia would have had an unremarkable career had he not been mentioned by the early Byzantine historian Agathias as one of seven Hellenic (non-Christian) philosophers who journeyed to the Sasanian court at Seleucia-Ctesiphon early in the reign of the Byzantine emperor Justinian (527-565).(1) These philosophers felt compelled to leave the Byzantine Empire because "they did not share the view of God prevailing among the Romans and thought that the Persian state was far better."(2) Although the Hellenic philosophers decided to return to Byzantine territory after a relatively brief sojourn at the Sasanian court, the philosophers did participate in at least one debate on philosophical questions attended by the shah himself and some higher ranking members of the Zoroastrian clergy. Priscianus of Lydia's contribution to this debate, Solutionum ad Chosroem, has survived in an edition edited by Ingram Bywater in 1886 and now difficult of access.(3) Bef ore considering the specific contents of Priscianus' surviving work, an examination of the historical context in which the work was written is necessary. The Context of Priscianus of Lydia's Solutionum ad Chosroem Agathias states that Priscianus and the other Hellenic philosophers travelled to the Sasanian Empire partly for religious reasons. Being pagans in an increasingly officially Christian empire had rendered their teaching positions more and more vulnerable.

Lifetime of Color Essay

In the 1900s, the world was suddenly enveloped by vagueness and uncertainty on what the future will bring. Prior to this period, the ambience was definite and secure. In relation to the art world, many artists were trying to outgrow the traditional styles that flourished all over the world. They wanted to create something different based from the conventional aesthetics popularized by the Renaissance. These artisans were considered as the founders of Modernism because they were trying to search for ways on how to display their new found outlook to ambiguity. This scenario laid the grounds for the founding of Cubism. This avant-garde art style movement began when a French painter called Paul Cezanne began to change his Impressionist style. Cezanne shifted from painting landscapes with pastel colors and soft brushstrokes to concentrating on portraying his own interpretation of the â€Å"shapes and forms† and he stayed away from rendering a realistic pictorial output. More so, he put more importance on the painting as a whole rather than focusing on the subject or the theme. Then, another artist came into the picture named Henri Matisse who also paved the way for the development of Cubism. Together with Louis Vauxcelles, an art critic and French journalist who â€Å"coined the term ‘les fauves’ (the wild animals) for the artists of Fauvism,† Matisse discovered an unusual painting by George Braque at the â€Å"Salon d’ Automne. † He said that the artwork incorporated â€Å"little cubes. † Braque’s painting showcased the landscape of the South of France with a surprising twist of including â€Å"two ascending lines meeting at the top and between several cubes. † This work of art provided artists who were looking for change with a new direction. Braque was the very first artist to create a cubist painting. Since then, despite the negative criticisms, cubism became an established style and art movement. The term â€Å"cubism† was developed by Vauxcelles when he was writing a report about the â€Å"Salon des Independants in 1909. † Through the ingenuity and innovation of Pablo Picasso and Georges Braque, cubism has gained a big following in France and rest of the world. According to Picasso, Cubism has tangible goals. We see it only as a means of expressing what we perceive with the eye and the spirit, while utilizing the possibilities that lie within the natural properties of drawing and color, That became a source of unexpected joy for us, a front to discoveries. (Gantefuhrer-Trier, Gantefuhrer and Grosenick 2004, 6) It is evident that Cubism is the brainchild of Picasso and Braque. They were responsible for the proliferation of a modern, radical and powerful art style that significantly influenced the 20th century. The main focus of this style and movement is the â€Å"complete denial of Classical conception of beauty. † The untrained eye evaluated the by-products of the cubists as perplexing but for the avant-garde, they perceived cubism as the way to the future. In cubism, many traditional elements such as proportions, lines, perspective and forms are distorted. As a result, the visual representation looked like â€Å"a field of broken glass. † Because of this, cubism became known for its â€Å"geometrically analytical approach to form and color, and shattering of object in focus into geometrical sharp-edged angular pieces. † To form these unusual shapes, a systematic deconstruction was employed to create an illusion of three- dimensionality. Many cubists doubted the integrity of â€Å"whole† images because for them these were the synthetic and conventional outputs of the past artisans. They believed that â€Å"perspective space is an illusory, rational invention, or a sign system inherited from works of art since the Renaissance. Moreover, cubism has two major branches namely: Analytical cubism and Synthetic cubism. The former is defined as the intellectual distortion of a subject matter producing hard to interpret and ambiguous materials. Meanwhile, the latter is more â€Å"experimental nature of a collage† and highly decorative. It is easier to comprehend than analytic cubism because the images and forms are not that distorted and abstract. Since its inception, Cubism became a worldwide phenomenon in the field of art. It continues to challenge artists even in the contemporary period to advance the art style and the movement to better reflect culture and society. Pioneers of Cubism The growth of cubism in the 20th century is accredited to Pablo Picasso and George Braque. Both worked hand in hand in exploring and at the same time experimenting with a technique aimed at flattening space. They utilized bold colors, raw shapes and flattened space to display their non-conformist approach towards art. It was the focus on conveying emotions rather than the â€Å"intellectual experiment with structure† that set cubism from other avant-garde movements such as Fauvism. Pablo Picasso Pablo Picasso was a native of Spain. At an early age, he was already producing remarkable works of art. In the early 1900s, Picasso moved to Paris where he developed an artistic phase called the Blue period. This was the time when he used various â€Å"shades of blue† in portraying the darker side of particular place. By the time he met Fernande Oliver, Picasso’s gloomy works transformed into bright shades of red that became known as his Rose period. The circus theme seemed to be the favorite subject of Picasso during this period. By 1906, he went to Spain that marked another modification in his art style. During his stay there, he was greatly influenced by â€Å"African, Green and Iberian art. † He incorporated geometrical forms that made his paintings very forward-looking. Then, Picasso met another intriguing artist named George Braque. In 1908 to 1911, they developed a unique style of painting landscape wherein they included cube shapes or forms in the picture. This became known as analytic cubism. This style was formed by â€Å"by breaking down and analyzing a object† and utilizing a monochromatic earthy brown color scheme. By 1912, Picasso started to use other elements in his artworks that resulted to the creation of collages which is also known as synthetic cubism. This style is more for decorative purposes. In the late 1920s, Picasso moved to Rome, Italy where he got married. In this period, he painted â€Å"neoclassical pictures of women and pictures inspired by Greek mythology. † By the time WWI broke out, Picasso created Guernica, to demonstrate his opposition over the bombing of â€Å"Basque town of Guernica on April 26, 1937 during the Spanish Civil War. † The painting was filled with symbolisms that represented the wickedness attached with the bombing. By the time of the end of WWII until Picasso’s death in 1973, his paintings veered towards more somber theme dealing about death. Some of Picasso’s famous artworks include Woman with a Crow (1903), Les Demoiselles d’Avignon (1907), Geometric Composition: The Guitar (1913) and many others. George Braque On the other hand, George Braque also lived a full life personally and professionally in the realm of art. He studied painting at the â€Å"local art school in Le Havre,† France. This was followed by a more formal training at the â€Å"Academie Humbert and at the Ecole des Beaux-Arts in the studio of Leon Bonnat. † Braque started out with impressionism wherein he was influenced by Matisse and Derain. By 1906, he got immersed with Fauvism and started to use light and bright colors combined with undulating patterns. But he stood out from the rest of the fauvists when he employed â€Å"architectonic solidity of composition and an emphasis on strongly defined volumes rather than color and brushwork. † The year 1907 became a crucial time for Braque and cubism. This was the time when Braque was once again inspired by Paul Cezanne and this was also the time when he met Pablo Picasso. Because of them, Braque’s outputs developed into something more radical. After only three years, the tandem of Braque and Picasso produce a new form art style called the analytic cubism which is described as the â€Å"nonillusionistic and nonimitative method of depicting the visual world. † The partnership of these two artists was mutual and their connection was so strong that their artworks cannot be distinguished from one another. The Violin and Pitcher (1910) is a very suitable example of an analytic cubism by Braque. Most of his paintings during this period were fragmented resulting to a â€Å"compact pictorial structure. † In 1914, Braque ventured into another phase of cubism which was called synthetic cubism wherein the artistic treatment included the use of â€Å"brightly dotted decorative passages. † Then, he moved to Normandy, France in the 1930s which have influenced Braque to shift his themes to seascapes. His painting style employed the use of â€Å"ornamentation and patterned surfaces. † From the 1930s to the 1950s, Braque grew interests on birds, melancholic themes, brilliant fauvist colors that were all seen in his â€Å"sculptures, graphics, book illustration, and decorative art. † Famous Cubist Artworks In the early 20th century, a new wave of artists have emerged that embraced a new progressive art style that had made a significant influence in the art world and the rest of the society and this was Cubism. This innovative movement aided in the development of contemporary art. More so, cubism led to the activation of many artists’ creative geniuses and induction of their bravery to go against the flow. Because of this, numerous masterpieces have emerged that embodied the unique principles and avant-garde style of cubism. Les Demoiselles d’Avignon by Pablo Picasso (1907) This painting showed Picasso’s portrayal of sexuality and his defiance over the traditional rules on visual elements and principles of design. The images integrated illustrated five naked female â€Å"prostitutes in a brothel. † In terms of form, human bodies were deformed with distorted body proportions. Also, out of the five figures, three were wearing ancient African masks that made the painting more interesting. More so, the â€Å"bold, brash diagonal lines and angular planes added a sense of violence to the composition. † The colors used were a mix of bold hues of reds and blues that were combined with the subtle pink and flesh tones. Through this, each figure was able to stand out from one another. Another intriguing factor of the painting is the â€Å"two central figures† that appeared to be looking directly at the viewers. This was probably intentional on the part of Picasso to grab the attention of the viewers. The Les Demoiselles d’Avignon is one of the first models for analytic cubism that successfully demonstrated that three dimensionality can be achieved even without the employment of perspective. Violin and Pitcher by Georges Braque (1909-1910) This still life painting is another example of analytic cubism. Based on the title, the main focus of this artwork is the violin and the pitcher. Many believed that Braque developed a fascination with musical instruments even if he did not know how to play. For him, painting these instruments was his way of showing his departure with naturalism. The treatment on the primary figures was distorted in order to illustrate disintegration. The violin was twisted at the bottom to make the other parts more visible. On top of the violin is the pitcher that was also drawn in fragments to create an illusion of depth. The contrast of the shades of red and grey added more dramatic effect to the series of geometric shapes strewn all over the canvas. There is also a nail on top of the painting but it serves no real purpose unlike in Braque’s earlier painting, Violin and Palette. Underneath the nail is a â€Å"piece of paper† wherein the top right corner was folded that provided a flattening effect on the plane. This also projected a shadow that created an illusion of light â€Å"being beamed down from the top right corner. † Glass of Beer and Playing Cards by Juan Gris (1913) Juan Gris was part of the founding of Cubism together with Braque and Picasso. He pushed for the advancement as well as for the growth of this art movement. In his painting of the Glass of Beer and Playing Cards, it is ruled over by vertical lines that divide the canvas into several segments. A coherently silhouetted beer mug might be established by shifting the vertical band that constitutes the right side of the mug upward so that the white outline becomes contiguous with the outline of the fully modeled form of the mug to its left. But this realignment would in turn disalign the continuity between the blue curvature on the orange wallpaper and the edge of the sand to the right, both forms constituting a view from above of the beer’s foam. Changes or transformations in the appearance of an object seem to occur in a number of directions: they follow the alternating rhythm of vertical bands but also the contrapuntal system of horizontal bands. Occasionally there is also a sense of transformations occurring in depth, as if Gris had peeled away the surface of certain vertical bands to reveal an alternate mode of representation or point of view beneath. Still Life with Chair Cane by Pablo Picasso (1912) This is first painting of Picasso to represent synthetic cubism. It was one of the first illustrations of a collage painting. The elements present in the artwork are woven chair cane, various geometric drawings, newspapers, painted letters and wine labels which were all encapsulated by a rope around the oval canvas. In contrast with analytic cubism, this painting is less on deconstruction but more on juxtaposing different elements for decorative purposes. Since there is only a minimal presence of fragmentations, depth is nonexistent making the painting more flat. Art in the 1900s During the 1900s, several other art movements have emerged aside from Cubism. Some of these movements were the Abstraction, Fauvism, Futurism, Dadaism and Surrealism. The only common factor that binds these art movements is their ability to reject tradition and their flair for the modern aesthetics. In abstraction, the artists choose not to depict reality. The images are disfigured, the details are left out and the conventional perspective is altered. Meanwhile, Fauvism is known for its use of colors in portraying emotions. Fauvists created their masterpieces by imperfectly treating colors in an arbitrary style. On the other hand, Futurism is characterized by the abandonment of the â€Å"static and irrelevant art of the past and celebrating change, originality and innovation in culture and society. † This style celebrates the power and vivacity of machines. Moreover, Dadaism is another movement that garnered positive as well as negative feedbacks from art aficionados. This style is defined as â€Å"nihilistic, anti-aesthetic and a reaction to the rationalization, rules and conventions of mainstream art. † For Dada artists, their artworks are intended to be anti-art. The last movement is Surrealism which existed through the art style of Dadaism. Surrealist art was greatly influenced by the â€Å"theories of Dr. Sigmund Freud and the unconscious† which are represented in a dream or fantasy-like manner in paintings. Though cubism had a lot of competition, it still managed to continue to influence 1920s and even way beyond to the contemporary period. Today, many modern artists are using cubism in sculptures and architecture. Cubism had become more bold and experimental. It seemed like the artists have eliminated all boundaries for the sake of the enrichment of their creativity. Like in the 1900s, many modern artists are still faced with several challenges on how to make their artworks more pleasing to the public eye but at the same time they still want to render a significant importance to their own point of view in order not to compromise their artistic integrity for public support. The House of the Black Madonna in Czech Republic and Cal Poly Pomona University library in California symbolized that the spirit and philosophies of Cubism during its initial phase are still as intense and provocative as it is today. Conclusion In conclusion, Cubism has created a revolution in the world of art. It defied the conventions and traditional practices that have dominated in the 1900s. For many artists, it was not easy to challenge the existing status quo. But because of their yearning for change and their craving for stimulation, they were able to withstand the scrutiny and rejection made by society. Through the resilience and the drive of the cubist style for progress, it was able to endure the test of time that it continues to persist in the 21st century. Moreover, this art style and movement is an evident symbol of how human beings can perceive the world in a totally different way. More so, cubism has showcased the value of intellectual freedom and distinctive aesthetic, in which significantly contributed to the development of the visual art. Overall, cubism is a form of art that will keep on evolving for the expression and celebration of human’s vision, passion and imagination. BIBLIOGRAPHY â€Å"Art timeline. † 2007.

Gummy Bear Experiment

Combustion of Gummy Bears Energy is a concept.? Most definitions of the word energy fail to provide its exact meaning when applied to scientific matters.? In science the word energy is a concept that expresses two measurable properties, heat and work.? Here is the relationship of energy, heat and work: Energy Released=Work Done + Heat Released The Law of Conservation of Energy, derived from centuries of observation and measurement, indicates that energy cannot be created or destroyed. But energy need not stay in one place. Energy can be converted from one form to another and can be created in one place and show up in another. Remember that energy, in an open system, can do work on the surroundings or supply heat to the surroundings.? When we express energy as the sum of heat and work, we are making a very specific claim concerning these two properties. They are related. The relationship between heat and work is a close one, so close the amount of heat and the amount of work must be expressed with numerical values having the same units. Within limits, energy may be controlled to appear as heat (as we use electric power to dry clothes in a dryer) or work (the same electric power rotating the drum in the same dryer). Briefly, we define the amount of heat and/or work using two units, the Joule (J), and the calorie. The Joule and the calorie are related as follows: 1 cal = 4. 184J Both units represent quite small increments of energy. We must add 1 calorie of heat to increase the temperature of 1g of water 1 degree Celsius. Our bodies expend about 1J of work with a single heartbeat. For convenience sake, both the Joule and calorie are often expressed in multiples of 1000. We speak of the kilojoule (kj): 1 kJ = 1000J and the kilocalorie (kcal). 1 kcal = 1000 cal Thus we must add 4. 184 kJ of heat to raise the temperature of 100g of water 10 degrees Celsius. Chemical Reactions and the Production of Energy Heat and Work We learned the foundation of thermochemistry rests on the ability to link the amount of energy released or required to the chemical equation for the specific chemical change. We often experiment under conditions where no work is done on or by the system.? The heat, evolved or required is the change in enthalpy. We use the change in enthalpy of the fuel-consuming chemical reactions to arrive at the energy that would be available. The amount of energy available from a given amount of fuel does not vary with how slow or fast we burn the fuel such as in exercise. Enthalpy itself is a state property. All materials have enthalpy as an element of their nature. It is the change in this property through chemical processes which concerns us. The oxidation of 0. 5g of glucose yields a certain amount of energy regardless of how slow or fast the reaction takes place.? In the real world (during exercise for example), energy, work and heat, are produced in complex, changing systems. The combustion of a gummy bear shows how a compound is broken down into an element and other compounds in the presence of a catalyst or heat. An organic carbon compound will combine with oxygen to give off carbon dioxide and water. An exothermic reaction releases different forms of energy. Sugar is a fuel that we use for energy. We can also use it to fuel a chemical reaction. As we heat the Potassium Chlorate this will release O2 gas and leave KCl as it starts to decompose as follows: 2KClO3(s) ? 2KCl(s) + 3O2 (g) This produces oxygen which oxidizes the sugar (glucose) in the gummy bear. This oxidation is incredibly exothermic (-5000 kJmol-1). The reaction is: C6H12O6(s) + 6O2 (g) ? 6CO2 (g) + 6H2O (g) All chemical reactions involve a change in substances and a change in energy. Neither matter nor energy is created or destroyed in a chemical reaction only changed. This experiment is a decomposition reaction a more complex substance breaks down into its more simple parts. One reactant yields 2 or more products. The presence of oxygen in the decomposition reaction is seen when heat energy is added to potassium chlorate, and its decomposition releases O2 and leaves KCl, when bubbles form. Heat is necessary in this reaction because the excess of oxygen, generated by the decomposition of potassium chlorate, will react with the glucose in a gummy bear, releasing a large amount of energy quickly and dramatically. When it comes in contact with the oxygen in the test tube some of the sucrose disintegrates and this releases heat energy. The released heat causes the potassium chlorate to release more oxygen and a positive feedback loop develops. The difference between endothermic and exothermic reactions is that endothermic reactions absorb heat, and exothermic give off heat. Dilution of ammonium chloride is an example of an endothermic reaction. This is the active ingredient in chemical ice packs you can obtain in a pharmacy. Other reactions are melting and boiling which also absorb heat to happen, although you may not consider them chemical reactions. Combustion is a typical exothermic reaction any type of burning. An exothermic reaction occurs if the energy of the bonds formed in the products are stronger (lower energy) than the bonds broken in the reactants. Endothermic reactions require heat. If there is no external source, the reaction gets the heat by cooling to a lower temperature. These reactions are driven by the change in the configuration of the atoms. If the atoms in the product molecules have a less orderly structure than the atoms in the reactants, these reactions will occur even if the cost some energy to happen. Potassium Chlorate is the oxidizing agent and when it is melted; its decomposition provides an oxygen rich environment. A gummy bear is dropped into the liquid and immediately begins to combust. The heated mixture ignites and oxidizes the sugar in the gummy bear in a violent, exothermic reaction. The gummy bear explodes because the combination of one gummy bear which is composed mostly of sucrose with molten potassium chlorate the gummy bear explodes. A surprising amount of energy is released by the reactants and in the process their atoms and molecules rapidly rearrange to form the products carbon dioxide, water and potassium chloride. The products of the reaction are H2O (vapor) and CO2. Ideally, a balanced equation would show sucrose (C12H22O11) being converted to carbon dioxide and water while the KClO3 becomes KCl. But the combustion was incomplete and carbon and or carbon monoxide were additional products.

Learn About the Science of Marine Biology

Learn About the Science of Marine Biology The field of marine biology or becoming a marine biologist sounds fascinating, doesnt it? Whats involved in marine biology, or becoming a marine biologist? First, its important to understand what, exactly, makes up the marine biology branch of science. Marine biology is the scientific study of plants and animals that live in salt water. When many people think about a marine biologist, they picture a dolphin trainer. But marine biology is so much more than making a dolphin or sea lion follow commands. With the oceans covering over 70 percent of the Earth’s surface and providing habitat for thousands of species, marine biology is a very broad field. It involves a strong knowledge of all science along with principles of economics, legal matters, and conservation. Becoming a Marine Biologist A marine biologist, or someone who studies marine biology, can learn about a variety of organisms during their education from tiny plankton only visible under a microscope to the largest whales that are over 100 feet long. Marine biology can also include the study of different aspects of these organisms, including the behavior of animals in the ocean environment, adaptations to living in salt water and interactions between organisms. As a marine biologist, one would also look at how marine life interacts with different ecosystems such as salt marshes, bays, reefs, estuaries, and sand bars. Again, its not just learning about things that inhabit the ocean; its also about conserving resources and protecting a valuable food supply. Plus, there are many research initiatives to discover how organisms can benefit human health. Marine biologists have to have a thorough understanding of chemical, physical, and geological oceanography. Other people who study marine biology do not go on to conduct research or work for activist organizations; they can wind up teaching others about the vast scientific principles that make up the field. In other words, they can become teachers and professors at universities and colleges. Tools to Study Marine Biology The oceans are difficult to study, as they are vast and foreign to humans. They also vary depending on geographic locations and environmental factors. Different tools used to study the oceans include sampling mechanisms such as bottom trawls and plankton nets, tracking methods and devices such as photo-identification research, satellite tags, hydrophones, and â€Å"critter cams,† and underwater observation equipment such as remotely operated vehicles (ROVs).   Importance of Marine Biology Among other things, the oceans regulate climate and provide food, energy, and income. They support a variety of cultures. They are so important, yet there is so much we don’t know about this fascinating environment. Learning about the oceans and the marine life inhabiting them is becoming even more critical as we realize the importance of the oceans to the health of all life on the planet.

Battered Praise

Kneel on a worn leather cushion, ease into a creaky wooden pew, and stand on tired but restless legs. For what? Even with all of my praise, all God did was throw me onto the corner ropes of the ring and deliver a sharp jab with the left, then the right, right again, and finally a roundhouse kick that shouldve stopped all of the pain but never did. God didnt deliver the real blows, he let a swaggering drunk do his work for him, also known as my stepfather. From the time I was four, I carried around fresh pink, swollen welts and indigo-violet bruises blooming quickly beneath my delicate skin. While other little girls neat hair was pinned back to reveal a bright, shiny face and toothy grin, my jagged homemade haircut hung to hide the new fleshy welt on my cheek. I firmly believed God had let this happen. I never questioned the reality of God, but I questioned his righteousness. I existed to God as a punching bag. I blamed the ever-so-righteous God for all of my problems. I blamed him for the hot tears that streamed from my cerulean blue eyes, for the crippling nightmares that plagued my nights, and for the screams of my brothers that rang through the hollow halls of that broken house. God never seemed to hear my desperate prayers each night or my withered cries of pain as Warren repeatedly smacked my tiny body with a wooden spoon, or an aluminum baseball bat, or even the time he broke a glass plate over my head. The loud sound of breaking glass must have drowned my pleas. I was all alone in my suffering. It took eight long years to finally be rid of the brutal man who beat my body, crushed my hopes and dreams, and demolished my self esteem. Thats 2,920 days of endless tears, 70,080 hours of countless bruises, 4,204,800 minutes of praying for salvation, and 252,288,000 seconds of pur e hatred toward God and toward myself. Then one day it ended. Warren had thrown a swing at my mother and hit her square in the jaw. The police showed up for the hundredth time, but this time I left in my dads car with my three brothers, my mom left in an ambulance, and Warren left in handcuffs. Since that day six years ago I have lived with my wonderful father and stepmother. They strive to give me every opportunity to help me create the life I have chosen. Im growing to appreciate the person I am. My stare pierces the girl looking back at me from the mirror, and I still see a broken, terrified child cowering behind two miniscule hands. I see something else in that same reflection, I see a strong, independent woman who loves friends, family and life passionately throughout every moment of the day. A woman running toward a shining future. Now there are times where I see every flaw in myself, but who doesnt? Im human. Im allowed to have imperfections. Ive grown to trust God and to believe he is an ever-loving God. He wasnt torturing me, he was building me into the original, gorgeous, tenacious woman I am today.

Business ethic case - Essay Example Counselors have a responsibility to help mitigate the damage done by racism in the workplace. Companies have a responsibility to act justly toward their employees and shareholders. Government has a responsibility to protect the liberty of its citizens. Minorities have a responsibility to speak out against such oppression wherever possible. The majority has a responsibility to protect the weak. Employees have a responsibility to their employers and co-workers to maintain an egalitarian work ethic. Ultimately, the primary stakeholders are individual families, the only stakeholders who are secondary victims of a racist corporate culture. Consider the roots of workplace racism proactively. What causes racism in the workplace? It could be a matter of resources. There may not be enough jobs to go around and people want those of their own race to benefit over others, or it could be a matter of personal intent. People tend to express aggression toward those they see as somehow inferior either physically, mentally or socially. Usually, this tends to be a matter of self-esteem. What understanding must people have to avoid workplace racism? The basic belief everyone must adopt in order to avoid racially charged conflict at work is simple. We must understand that although we may not all look, think, and act alike, everyone has the right to live and survive peaceably within our society. That means although I may not like a person for whatever reason, I should give them the room they need to provide for themselves and their families. If there is no other reason I feel this way, it should be because I wish for the same. If othe rs feel hostile toward me, I want them to leave me alone enough to feel secure in my job and at home at the very least. Some thinkers have posited this notion as the basis for the social contract. Why do humans not simply overrun one another with force and
