The Evolution of the Graphic Industry Essay Example for Free
The Evolution of the Graphic Industry Essay The development and continuous improvement of technology has incessantly provided new professional fields that emerged to cater to the intensification brought about by the web explosion and digital breakthroughs in the industry. The creative spectrum in the graphic industry has open doors to a large number of occupations which careers may in some way or another extend beyond one particular expertise. Visual communication is the medium used by the artists to provide people the distinction between graphic design, fine art and even advertising art. Different industries that make use of visual tools most of the time utilize almost the same theories, principles, practices, languages and even elements in delivering their clientââ¬â¢s needs. The book ââ¬Å"A history of graphic designâ⬠conveys that the industryââ¬â¢s main essence is to provide arrangement to information, form to designs, feelings and expressions to a work of art which primary output is the documentation of human experience (Meggs, 1983). The graphic industryââ¬â¢s professional fields have high-racketed immensely that make way to the diversity of graphic designing jobs. The workforce in the graphic design business which holds the management related roles are creative directors, art directors and art production managers. Hands-on designers in the fields are logo designers, brand identity developers, visual image developers, illustrators, content developers, multimedia developer, visual journalists and layout artists. The web explosion and advancement opened its doors to interface layout artists and web designers usually employed by web development companies. Web design may entail collaboration of graphic designers and software engineers. Programmers are also in demand in the field of web development to provide their expertise in doing advance coding. Web masters are positions that specialize in both programming and web design. While traditional graphic design and interactive design both adhere to provide better physical facade, the two have distinguished characteristics from the other. At all times, traditional graphic designââ¬â¢s main purpose is to carry out an attractive application of an object. It is relatively eye-catching and bold. The layout of this kind of design deals primarily with the style treatment and array of a printââ¬â¢s content. The interactive design on the other hand, is mainly the design used in appliances, machines, CD software applications, mobile communications, computers and even websites which focus intensively on the user interaction and experience. It aims to proficiently deliver to a user an interaction that is both efficient and simple. Interactive design is also referred to as user-centered design. Traditional graphic design is utilized to please the eyes of each and every observer. It is highly used in logo design whereas it uses a process of sketching through thumbnails and rough drafts prior to hybrid process (Gregory 48). Interactive design process balances the visual elements with regards to the operational mode and the functionality of the system to make it usable and make it easily adjust to the userââ¬â¢s changing requirements and needs. Interactive design is widely used in the web. Web page designs give the internet users an active role in accessing what they need online. The more user-friendly a site is the more it is visited. The interactive design reflects lucid pathways to the information, products and tools a user necessitates. Design is fundamental to the success of most services and products released by a company. Both the graphic and the interactive design of a product and affect the consumer experience which directly and enormously affects the business success or failure. The profound impact of design is apparent as dictated by the developments in technology.

The Use of ERGs for Early Glaucoma Detection :: Medicine Medical Medicinal Essays
The Use of ERGs for Early Glaucoma Detection Glaucoma is a degenerative disease which can be caused by high intraocular pressure (IOP) (Glaucoma, 2002). This IOP arises in the aqueous humor, the area between the cornea and the iris, where a drainage system allows the aqueous to drain from this area and recycle (Learn about Glaucoma, 2002). A specific balance of the production and removal of aqueous determines the IOP. Either malfunction or malformation of this drainage system can cause a rise in pressure. The elevated pressure causes irrevocable damage to the optic nerve and retinal fibers as well as damage to the other areas of the visual system, which leads to a gradual and permanent loss of vision if not treated (Glaucoma, 2002). Damage to the optic nerve causes loss of vision because this nerve, or group of ganglion axons, is responsible for transporting images to the brain from the eye. While there are other possible causes of glaucoma, such as variations of the myocilin gene, IOP is thought to be the main cause (Learn abo ut Glaucoma, 2002). Treatment, especially with early detection, can slow or cease continued damage. Types of Glaucoma There are several types of glaucoma, the most prominent types being Open Angle, and Acute Angle Closure and the more infrequent types including Secondary Glaucoma, Congenital Glaucoma, Normal Tension Glaucoma (NTG), and Pigmentary Glaucoma. Open Angle Glaucoma (OAG), the most prevalent form of glaucoma (Glaucoma, 2002), is painless, and can go unnoticed without the help of an optometrist or ophthalmologist. Obstructed drainage channels, which develop over a period of time, characterize this type of glaucoma. These obstructions are not present at the openings of the channels, rather they occur inside the channels. The aqueous cannot recycle because of these obstructed channels, the IOP rises, and damage results (Learn about Glaucoma, 2002). Acute Angle Closure Glaucoma, however, is much more painful and results in rapid vision loss. In this case, the iris and cornea are not wide enough apart which can cause the edge of the iris to block the drainage channels (Learn about Glaucoma; and Glaucoma, 2002). Secondary Glaucoma results from other eye diseases or problems, such as diabetes, trauma, and tumors . Congenital Glaucoma is a rare glaucoma found in infants (Glaucoma, 2002). Normal Tension Glaucoma occurs in those with normal IOPââ¬â¢s but have damage to the optic nerve. Pigmentary Glaucoma results from parts of the pigment in the iris breaking off and slowly clogging the drainage channels.

Animal Nutrition: Distinguish Macronutrients and Micronutrients Essay
There are seven major classes of nutrients: carbohydrates, fats, fiber, minerals, protein, vitamin, and water. These nutrient classes can be categorized as either macronutrients (needed in relatively large amounts) or micronutrients (needed in smaller quantities). The macronutrients are carbohydrates, fats, fiber, proteins, and water. The micronutrients are minerals and vitamins. The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some of the structural material can be used to generate energy internally, and in either case it is measured in joules or calories (sometimes called ââ¬Å"kilocaloriesâ⬠and on other rare occasions written with a capital C to distinguish them from little ââ¬Ëcââ¬â¢ calories). Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram.,[1] though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons. A third class dietary material, fiber (i.e., non-digestible material such as cellulose), seems also to be required, for both mechanical and biochemical reasons, though the exact reasons remain unclear. Molecules of carbohydrates and fats consist of carbon, hydrogen, and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose, fructose, galactose) to complex polysaccharides (starch). Fats are triglycerides, made of assorted fatty acid monomers bound to glycerolbackbone. Some fatty acids, but not all, are essential in the diet: they cannot be synthesized in the body. Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen. The fundamental components of protein are nitrogen-containing amino acids, some of which areessential in the sense that humans cannot make them internally. Some of the amino acids are convertible (with the expenditure of energy) to glucose and can be used for energy production just as ordinary glucose. By breaking down existing protein, some glucose can be produced internally; the remaining amino acids are discarded, primarily as urea in urine. This occurs normally only during prolonged starvation.

They constitute a large part of foods such as rice, noodles, bread, and other grain-based products. Monosaccharides contain one sugar unit, disaccharides two, and polysaccharides three or more. Polysaccharides are often referred to as complex carbohydrates because they are typically long multiple branched chains of sugar units. The difference is that complex carbohydrates take longer to digest and absorb since their sugar units must be separated from the chain before absorption. The spike in blood glucose levels after ingestion of simple sugars is thought to be related to some of the heart and vascular diseases which have become more frequent in recent times. Simple sugars form a greater part of modern diets than formerly, perhaps leading to more cardiovascular disease. The degree of causation is still not clear, however. Fat A molecule of dietary fat typically consists of several fatty acids (containing long chains of carbon and hydrogen atoms), bonded to a glycerol. They are typically found as triglycerides (three fatty acids attached to one glycerol backbone). Fats may be classified as saturated or unsaturateddepending on the detailed structure of the fatty acids involved. Saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded, so their molecules have relatively fewer hydrogen atoms than a saturated fatty acid of the same length. Unsaturated fats may be further classified as monounsaturated (one double-bond) or polyunsaturated (many double-bonds). Furthermore, depending on the location of the double-bond in the fatty acid chain, unsaturated fatty acids are classified as omega-3 or omega-6 fatty acids. Trans fats are a type of unsaturated fat with trans-isomer bonds; these are rare in nature and in foods from natural sources; they are typically created in an industrial process called (partial) hydrogenation. Many studies have shown that unsaturated fats, particularly monounsaturated fats, are best in the human diet. Saturated fats, typically from animal sources, are next, while trans fats are to be avoided. Saturated and some trans fats are typically solid at room temperature (such as butter orlard), while unsaturated fats are typically liquids (such as olive oil or flaxseed oil). Trans fats are very rare in nature, but have properties useful in the food processing industry, such as rancid resistance.[citation needed] Essential fatty acids Most fatty acids are non-essential, meaning the body can produce them as needed, generally from other fatty acids and always by expending energy to do so. However, in humans at least two fatty acids are essential and must be included in the diet. An appropriate balance of essential fatty acids -ââ¬â omega-3 and omega-6 fatty acids -ââ¬â seems also important for health, though definitive experimental demonstration has been elusive. Both of these ââ¬Å"omegaâ⬠long-chain polyunsaturated fatty acids are substrates for a class of eicosanoids known as prostaglandins, which have roles throughout the human body. They are hormones, in some respects. The omega-3 eicosapentaenoic acid (EPA), which can be made in the human body from the omega-3 essential fatty acid alpha-linolenic acid (LNA), or taken in through marine food sources, serves as a building block for series 3 prostaglandins (e.g. weakly inflammatory PGE3). The omega-6 dihomo-gamma-linolenic acid (DGLA) serves as a building block for series 1 prostaglandins (e.g. anti-inflammatory PGE1), whereas arachidonic acid (AA) serves as a building block for series 2 prostaglandins (e.g. pro-inflammatory PGE 2). Both DGLA and AA can be made from the omega-6 linoleic acid (LA) in the human body, or can be taken in directly through food. An appropriately balanced intake of omega-3 and omega-6 partly determines the relative production of different prostaglandins: one reason a balance between omega-3 and omega-6 is believed important for cardiovascular health. In industrialized societies, people typically consume large amounts of processed vegetable oils, which have reduced amounts of the essential fatty acids along with too much of omega-6 fatty acids relative to omega-3 fatty acids. The conversion rate of omega-6 DGLA to AA largely determines the production of the prostaglandins PGE1 and PGE2. Omega-3 EPA prevents AA from being released from membran es, thereby skewing prostaglandin balance away from pro-inflammatory PGE2 (made from AA) toward anti-inflammatory PGE1 (made from DGLA). Moreover, the conversion (desaturation) of DGLA to AA is controlled by the enzyme delta-5-desaturase, which in turn is controlled by hormones such as insulin (up-regulation) and glucagon (down-regulation). The amount and type of carbohydrates consumed, along with some types of amino acid, can influence processes involving insulin, glucagon, and other hormones; therefore the ratio of omega-3 versus omega-6 has wide effects on general health, and specific effects on immune function and inflammation, and mitosis (i.e. cell division). Good sources of essential fatty acids include most vegetables, nuts, seeds, and marine oils,[2] Some of the best sources are fish, flax seed oils, soy beans, pumpkin seeds, sunflower seeds, and walnuts. Fiber Dietary fiber is a carbohydrate (or a polysaccharide) that is incompletely absorbed in humans and in some animals. Like all carbohydrates, when it is metabolized it can produce four calories (kilocalories) of energy per gram. But in most circumstances it accounts for less than that because of its limited absorption and digestibility. Dietary fiber consists mainly of cellulose, a large carbohydrate polymer that is indigestible because humans do not have the required enzymes to disassemble it. There are two subcategories: soluble and insoluble fiber. Whole grains, fruits (especiallyplums, prunes, and figs), and vegetables are good sources of dietary fiber. Fiber is important to digestive health and is thought to reduce the risk of colon cancer.[citation needed] For mechanical reasons it can help in alleviating both constipation and diarrhea. Fiber provides bulk to the intestinal contents, and insoluble fiber especially stimulates peristalsis ââ¬â the rhythmic muscular contractions of the intestines which move digesta along the digestive tract. Some soluble fibers produce a solution of high viscosity; this is essentially a gel, which slows the movement of food through the intestines. Additionally, fiber, perhaps especially that from whole grains, may help lessen insulin spikes and reduce the risk of type 2 diabetes. Protein Proteins are the basis of many animal body structures (e.g. muscles, skin, and hair). They also form the enyzmes which control chemical reactions throughout the body. Each molecule is composed of amino acids which are characterized by inclusion of nitrogen and sometimes sulphur (these components are responsible for the distinctive smell of burning protein, such as the keratin in hair). The body requires amino acids to produce new proteins (protein retention) and to replace damaged proteins (maintenance). As there is no protein or amino acid storage provision, amino acids must be present in the diet. Excess amino acids are discarded, typically in the urine. For all animals, some amino acids are essential (an animal cannot produce them internally) and some are non-essential (the animal can produce them from other nitrogen-containing compounds). About twenty amino acids are found in the human body, and about ten of these are essential, and therefore must be included in the diet. A diet that contains adequate amounts of amino acids (especially those that are essential) is particularly important in some situations: during early development and maturation, pregnancy, lactation, or injury (a burn, for instance). A complete protein source contains all the essential amino acids; an incomplete protein source lacks one or more of the essential amino acids. It is possible to combine two incomplete protein sources (e.g. rice and beans) to make a complete protein source, and characteristic combinations are the basis of distinct cultural cooking traditions. Sources of dietary protein include meats, tofu and other soy-products, eggs, grains, legumes, and dairy products such as milk and cheese. A few amino acids from protein can be converted into glucose and used for fuel through a process called gluconeogenesis; this is done in quantity only during starvation. The amino acids remaining after such conversion are discarded. Vitamins As with the minerals discussed above, some vitamins are recognized as essential nutrients, necessary in the diet for good health. (Vitamin D is the exception: it can alternatively be synthesized in the skin, in the presence of UVB radiation.) Certain vitamin-like compounds that are recommended in the diet, such as carnitine, are thought useful for survival and health, but these are not ââ¬Å"essentialâ⬠dietary nutrients because the human body has some capacity to produce them from other compounds. Moreover, thousands of different phytochemicals have recently been discovered in food (particularly in fresh vegetables), which may have desirable properties including antioxidant activity (see below); experimental demonstration has been suggestive but inconclusive. Other essential nutrients not classed as vitamins include essential amino acids (see above),choline, essential fatty acids (see above), and the minerals discussed in the preceding section. Vitamin deficiencies may result in disease conditions: goitre, scurvy, osteoporosis, impaired immune system, disorders of cell metabolism, certain forms of cancer, symptoms of premature aging, and poor psychological health (including eating disorders), among many others.[6] Excess of some vitamins is also dangerous to health (notably vitamin A), and for at least one vitamin, B6, toxicity begins at levels not far above the required amount. Deficiency or excess of minerals can also have serious health consequences. Water About 70% of the non-fat mass of the human body is made of water[7] . Analysis of Adipose Tissue in Relation to Body Weight Loss in Man. Retrieved from Journal of Applied To function properly, the body requires between one and seven liters of water per day to avoid dehydration; the precise amount depends on the level of activity, temperature, humidity, and other factors.[citation needed] With physical exertion and heat exposure, water loss increases and daily fluid needs will eventually increase as well. It is not fully clear how much water intake is needed by healthy people, although some experts assert that 8ââ¬â10 glasses of water (approximately 2 liters) daily is the minimum to maintain proper hydration.[8] The notion that a person should consume eight glasses of water per day cannot be traced to a credible scientific source.[9] The effect of, greater or lesser, water intake on weight loss and on constipation is also still unclear.[10] The original water intake recommendation in 1945 by the Food and Nutrition Board of the National Research Council read: ââ¬Å"An ordinary standard for diverse persons is 1 milliliter for each calorie of food. Most of this quantity is contained in prepared foods.â⬠[11] The latest dietary reference intake report by theUnited States National Research Council recommended, generally, (including food sources): 2.7 liters of water total for women and 3.7 liters for men.[12] Specifically, pregnant and breastfeeding women need additional fluids to stay hydrated. According to the Institute of Medicineââ¬âwho recommend that, on average, women consume 2.2 litres and men 3.0 litresââ¬âthis is recommended to be 2.4 litres (approx. 9 cups) for pregnant women and 3 litres (approx. 12.5 cups) for breastfeeding women since an especially large amount of fluid is lost during nursing.[13] For those who have healthy kidneys, it is somewhat difficult to drink too much water,[citation needed] but (especially in warm humid weather and while exercising) it is dangerous to drink too little. People can drink far more water than necessary while exercising, however, putting them at risk of water intoxication, which can be fatal. In particular large amounts of de-ionized water are dangerous. Normally, about 20 percent of water intake comes in food, while the rest comes from drinking water and assorted beverages (caffeinated included). Water is excreted from the body in multiple forms; including urine and feces, sweating, and by water vapor in the exhaled breath.
