Types And Uses Of Fertilizers

Types And Uses Of Fertilizers Fertilizers are substances that supply plant nutrients or amend soil fertility. They are the most effective means of increasing crop production and of improving the quality of food and fodder. Fertilizers are used in order to supplement the natural nutrient supply in the soil, especially to correct the (yield-limiting) minimum factor. Fertilizers are soil amendments applied to promote plant growth; the main nutrients present in fertilizer are nitrogen, phosphorus, and potassium (the macronutrients) and other nutrients (micronutrients) are added in smaller amounts. Fertilizers are usually directly applied to soil, and also sprayed on leaves (foliar feeding). Organic fertilizers or and some mined inorganic fertilizers have been used for many centuries, whereas chemically synthesized inorganic fertilizers were only widely developed during the industrial revolution. Increased understanding and use of fertilizers were important parts of the pre-industrial British Agricultural Revolution and the industrial green revolution of the 20th century. Inorganic fertilizer use has also significantly supported global population growth it has been estimated that almost half the people on the Earth are currently fed as a result of artificial nitrogen fertilizer use. Fig 1 Fertilizers typically provide, in varying proportions: The three primary macronutrients: nitrogen (N), phosphorus (P), and potassium (K). The three secondary macronutrients: calcium (Ca), sulfur (S), magnesium (Mg). and the micronutrients or trace minerals: boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo) and selenium (Se). The macronutrients are consumed in larger quantities and are present in plant tissue in quantities from 0.2% to 4.0% (on a dry matter weight basis). There are some examples of it:- Fig 2 Fig 3 Different Types of Fertilizers Fertilizers are chemical compounds applied to promote plentiful plant and fruit growth. Fertilizers are applied through soil for uptake by plant roots, or by applying liquid fertilizer directly to plant leaves. They typical fertilizer provides proportions of the three major plant nutrients; nitrogen, phosphorus, and potassium. The secondary plant nutrients such as calcium, sulfur, and magnesium are also contained in fertilizers. Fertilizers can be placed into categories of organic fertilizers and inorganic fertilizers. Organic Fertilizers Naturally occurring fertilizers include: Manure Worm castings Peat moss Seaweed Sewage Guano Organic fertilizers are used to enrich soil through nitrogen fixation from the atmosphere by bacterial nodules on plant roots, as well as phosphorus content of soils. Processed organic materials from natural sources include compost, blood meal powdered blood, and bone (crushed ground bones) meal from organic meat production facilities, and seaweed extracts. There is more diversity with organic fertilizers, so choosing the right one is not always easy. In general organic fertilizers cannot cause plant burns, get into ground water, affect surrounding growth, and do not need as strict of watering schedules. Organic fertilizer sources:- Animals Animals:- Sourced urea , are suitable for application organic agriculture, while pure synthetic forms of urea are not. The common thread that can be seen through these examples is that organic agriculture attempts to define itself through minimal processing (in contrast to the man-made Haber process), as well as being naturally occurring or via natural biological processes such as composting. Sewage sludge use in organic agricultural operations in the U.S. has been extremely limited and rare due to USDA prohibition of the practice (due to toxic metal accumulation, among other factors). The USDA now requires 3rd-party certification of high-nitrogen liquid organic fertilizers sold in the U.S. Plant:- Cover crops are also grown to enrich soil as a green manure through nitrogen fixation from the atmosphere; as well as phosphorus (through nutrient mobilization) content of soils. Mineral:- Naturally mined powdered limestone, mined rock phosphate and sodium nitrate, are inorganic (in a chemical sense), are energetically intensive to harvest, and yet are approved for usage in organic agriculture in minimal amounts. Benefits of Organic Material By nature organic fertilizers provide increased physical and biological storage mechanisms to soils, reducing risks of over fertilization. Organic fertilizers nutrient content, solubility, and nutrient release rates are typically much lower than inorganic fertilizers. Over fertilization of a vital nutrient can be as detrimental as under fertilization to a plant. Fertilizer burn can occur when too much fertilizer is applied resulting in the drying out of roots along with damage and even death to plants. All organic fertilizers are classified as slow release fertilizers. Studies have found that organic fertilizers: Release 25% to 60% of nitrogen as inorganic. Controlled release fertilizers had a relatively constant rate of release. Soluble fertilizer released most of its nitrogen content at the first leaching. Inorganic Fertilizers: Naturally occurring inorganic fertilizers include sodium nitrate, mined rock phosphate and lime stone which is used to raise pH and calcium sources. Macronutrients and Micronutrients Fertilizers can be divided into macronutrients and micronutrients based on their concentration levels in dry plant matter. There are six macronutrients; nitrogen, phosphorus, potassium (3 main primary elements), calcium, magnesium, and sulfur. Macronutrient Fertilizers:- Synthesized materials are also called artificial, and may also be called straight were a product contains the three primary elements of nitrogen, phosphorus, and potassium. Fertilizers are named according to the content of the three elements in the fertilizer. If the main ingredient in the fertilizer is nitrogen, then the fertilizer will be described as a nitrogen fertilizer. But regardless of the name of the fertilizer they are labeled according to the amounts of each of these primary elements, by their weight. The amount of nitrogen will encourage growth of stems and leaves by promoting protein and chlorophyll. More Flowers, bigger fruits, and healthier roots will result from added phosphorus, and it will also help plants resist certain diseases. Potassium thickens stems and leaves by fostering protein development, meaning the vegetables would prefer a different potassium ratio than flowers or fruit plants would. Benefits of inorganic fertilizers Synthetic fertilizers are commonly used to treat fields used for growing maize, followed by barley, sorghum, rapeseed, soy and sunflower. One study has shown that application of nitrogen fertilizer on off-season cover crops can increase the biomass (and subsequent green manure value) of these crops, while having a beneficial effect on soil nitrogen levels for the main crop planted during the summer season. Nutrients in soil develop in symbiosis, which can be thrown out of balance with high concentrations of fertilizers. The interconnectedness and complexity of this soil food web means any appraisal of soil function must necessarily take into account interactions with the living communities that exist within the soil. Stability of the system is reduced by the use of nitrogen-containing inorganic and organic fertilizers, which cause soil acidification. Problem with inorganic fertilizers Trace mineral depletion:- Many inorganic fertilizers may not replace trace mineral elements in the soil which become gradually depleted by crops. This depletion has been linked to studies which have shown a marked fall (up to 75%) in the quantities of such minerals present in fruit and vegetables. In Western Australia deficiencies of zinc, copper, manganese, iron and molybdenum were identified as limiting the growth of broad-acre crops and pastures in the 1940s and 1950s. Soils in Western Australia are very old, highly weathered and deficient in many of the major nutrients and trace elements. Since this time these trace elements are routinely added to inorganic fertilizers used in agriculture in this state. Over fertilization:- Over-fertilization of a vital nutrient can be as detrimental as under fertilization. Fertilizer burn can occur when too much fertilizer is applied, resulting in a drying out of the roots and damage or even death of the plant. Burning of plants High energy consumption:- The production of synthetic ammonia currently consumes about 5% of global natural gas consumption, which is somewhat fewer than 2% of world energy productions. Natural gas is overwhelmingly used for the production of ammonia, but other energy sources, together with a hydrogen source, can be used for the production of nitrogen compounds suitable for fertilizers. The cost of natural gas makes up about 90% of the cost of producing ammonia. The increase in price of natural gases over the past decade, along with other factors such as increasing demand, has contributed to an increase in fertilizer price. Long-Term Sustainability:- Inorganic fertilizers are now produced in ways which theoretically cannot be continued indefinitely. Potassium and phosphorus come from mines (or saline lakes such as the Dead Sea) and such resources are limited. More effective fertilizer utilization practices may, however, decrease present usage from mines. Improved knowledge of crop production practices can potentially decrease fertilizer usage of P and K without reducing the critical need to improve and increase crop yields. Atmospheric (unfixed) nitrogen is effectively unlimited (forming over 70% of the atmospheric gases), but this is not in a form useful to plants. To make nitrogen accessible to plants requires nitrogen fixation (conversion of atmospheric nitrogen to a plant-accessible form). Artificial nitrogen fertilizers are typically synthesized using fossil fuels such as natural gas and coal, which are limited resources. In lieu of converting natural gas to syngas for use in the Haber process, it is also possible to convert renewable biomass to syngas (or wood gas) to supply the necessary energy for the process, though the amount of land and resources (ironically often including fertilizer) necessary for such a project may be prohibitive (see Energy conservation in the United States). Applications of fertilizer There are so many fields where fertilizer is used in high proportion. Agriculture is the one of field among them. There is some region where fertilizer is used:- Broadcast:- Broadcasting consists of uniformly distributing dry or liquid materials over the soil surface, usually before sowing. The fertilizer maybe incorporated into the soil mechanically, or left on the surface to be washed in by rainfall or irrigation. Incorporation into the AP horizon can be by harrow (2-3 cm depth), a cultivator (4-6 cm depth) or by plough (incorporation to plough depth). Broadcasting is the simplest and cheapest method and is best suited for high-speed operations and heavy application rates, especially before planting. Side or top dressing:- Fertilizer is side or top-dressed when it is applied after the crop has emerged, and/or when the dose is split for two or more applications. Split applications can be beneficial in some cases, especially for annual crops with a long growing period. Split application of KCl is also recommended for crops growing on low CEC soils, where K can be lost by leaching K following high rainfall or excess irrigation. Soybean responded significantly up to 50 kg K ha-1 when applied half at planting and half at flower initiation, or applying one third at planting, one third at flower initiation and one third at pod development. Splitting the K application is also used in orchards and for other perennial crops, especially for alfalfa and grasses. In trials in a Commercial field of Lucerne, the largest yields, up to 3.15 t ha-1 in 26 days, were on plots treated with 948 kg K ha-1 as KCl in 3 applications. In areas of Cl deficient soils, top-dressed applications of KCl for autumn sown small grains ma y be more effective than preplant applications because of the potential for Cl leaching from the root zone due to rainfall. Foliar application: Foliar application involves the use of KCl in solution. It results in fast K absorption and utilization and has the advantage of quickly correcting deficiencies diagnosed by observation or foliar analysis. Other advantages are low application rates, and uniform distribution of fertilizer. However, foliar fertilization is supplementary to and cannot replace the basal fertilization. Foliar application should be done during periods of low temperature and relatively high humidity, such in the early morning or late evening. Otherwise the salts may cause leaf burning and necrosis especially when applied in concentrations above those recommended. Because of its osmotic action, KCl applied on leaves is not well tolerated by plants and so is not usually used for foliar application. Nevertheless, it can be beneficial in some cases. Rice:- A foliar application of 10 kg KCl m-3 to rice at panicle initiation, boot leaf and 50% flowering stages, both in the monsoon and winter seasons, significantly increased seed yield and improved quality (seed germination and 100-seed weight). Splitting a total of 95 kg ha-1 of KCl to rice, a third at sowing in soil, a third as a foliar spray at flag leaf stage and a third as foliar spray at grain development, gave larger yields than a soil application all at sowing .A foliar spray applying 3.9 kg K ha-1 (as 10 kg KCl m-3) three times at one week intervals from full head of rice cv. Environmental effects of fertilizer use Water Eutrophication:- The nitrogen-rich compounds found in fertilizer run-off is the primary cause of a serious depletion of oxygen in many parts of the ocean, especially in coastal zones; the resulting lack of dissolved oxygen is greatly reducing the ability of these areas to sustain oceanic fauna.Visually, water may become cloudy and discolored (green, yellow, brown, or red). About half of all the lakes in the United States are now eutrophic, while the number of oceanic dead zones near inhabited coastlines are increasing. As of 2006, the application of nitrogen fertilizer is being increasingly controlled in Britain and the United States. If Eutrophication can be reversed, it may take decades before the accumulated nitrates in groundwater can be broken down by natural processes. High application rates of inorganic nitrogen fertilizers in order to maximize crop yields, combined with the high solubilitys of these fertilizers leads to increased runoff into surface water as well as leaching into groundwater. The use of ammonium nitrate in inorganic fertilizers is particularly damaging, as plants absorb ammonium ions preferentially over nitrate ions, while excess nitrate ions which are not absorbed dissolve (by rain or irrigation) into runoff or groundwater. Fig 10 Soil acidification: Nitrogen-containing inorganic and organic fertilizers can cause soil acidification when added. This may lead to decreases in nutrient availability which may be offset by liming. Heavy metal accumulation:- The concentration of up to 100 mg/kg of cadmium in phosphate minerals (for example, minerals from Nauru and the Christmas islands)increases the contamination of soil with cadmium, for example in New Zealand. Uranium is another example of a contaminant often found in phosphate fertilizers (at levels from 7 to 100 pCi/g). Eventually these heavy metals can build up to unacceptable levels and build up in vegetable produce. (See cadmium poisoning) Average annual intake of uranium by adults is estimated to be about 0.5 mg (500 ÃŽÂ ¼g) from ingestion of food and water and 0.6 ÃŽÂ ¼g from breathing air. Steel industry wastes, recycled into fertilizers for their high levels of zinc (essential to plant growth), wastes can include the following toxic metals: lead arsenic, cadmium, chromium, and nickel. The most common toxic elements in this type of fertilizer are mercury, lead, and arsenic. Concerns have been raised concerning fish meal mercury content by at least one source in Spain. Also, highly radioactive Polonium-210 contained in phosphate fertilizers is absorbed by the roots of plants and stored in its tissues; tobacco derived from plants fertilized by rock phosphates contains Polonium-210 which emits alpha radiation estimated to cause about 11,700 lung cancer deaths each year worldwide. For these reasons, it is recommended that nutrient budgeting, through careful observation and monitoring of crops, take place to mitigate the effects of excess fertilizer application. Atmospheric effects:- Methane emissions from crop fields (notably rice paddy fields) are increased by the application of ammonium-based fertilizers; these emissions contribute greatly to global climate change as methane is a potent greenhouse gas. Through the increasing use of nitrogen fertilizer, which is added at a rate of 1 billion tons per year presently to the already existing amount of reactive nitrogen, nitrous oxide (N2O) has become the third most important greenhouse gas after carbon dioxide and methane. It has a global warming potential 296 times larger than an equal mass of carbon dioxide and it also contributes to stratospheric ozone depletion. Storage and application of some nitrogen fertilizers in some weather or soil conditions can cause emissions of the potent greenhouse gas-nitrous oxide. Ammonia gas (NH3) may be emitted following application of inorganic fertilizers and/or manures and slurries. The use of fertilizers on a global scale emits significant quantities of greenhouse gas into the atmosphere. Emissions come about through the use of: animal manures and urea, which release methane, nitrous oxide, ammonia, and carbon dioxide in varying quantities depending on their form (solid or liquid) and management (collection, storage, spreading) fertilizers that use nitric acid or ammonium bicarbonate, the production and application of which results in emissions of nitrogen oxides, nitrous oxide, ammonia and carbon dioxide into the atmosphere. By changing processes and procedures, it is possible to mitigate some, but not all, of these effects on anthropogenic climate change.

Pretty Little Liars Essay

Are Pretty Little Liars good at keeping their dirty secretes? Pretty Little Liars a favorite ABC Family series is built around five teenage friends, until one goes missing and is found dead. It has a strong hint of supernatural force that mean no good. It makes most popular vampire romances look anemic. Because of a popular series of HarperTeen books by Sara Shepard, Pretty Little Liars follows the nervous lives of four girls in Rosewood, Pa. It’s a small town and these girls seem to have it all and that sets it up for an even better drama, when we start to see they also have secrets. The season premier starts with the disappearance and apparent death of the fifth girl in the circle, Alison DiLorentis. If the PLL series were traditional, Alison, Sasha Pieterse would have been the sweetest girl in school and no one could imagine anyone wanting to hurt her. If that’s what you’re expecting here, you’re wrong. Alison was a bitchy gossiper, backstabber and cruel practical joker. In any case, they were all together the night she disappeared and we join the story a year later, when free spirit Aria, Lucy Hale, nerdySpencer,TroianBellisario, crazy Hanna, Ashley Benson and jock Emily Shay Mitchell have drifted apart. Drug and alcohol use, foul language, scanty clothing, sexual innuendo and some passioate make-out scenes and homosexuality all make Pretty Little Liars a series that keeps viewers on their feet. Every episode leaves you with a cliffhanger. They run into each other in random chance encounters, however, that suggest each is harboring dark secrets, some related to Alison and some not. Since they apparently weren’t into deep sharing when they were all best friends then, they aren’t spilling now. Except they have two problems. A local cop is determined to find out what happened to Alison. Second, the girls all start getting mysterious messages that suggest some supernatural force knows all the secrets and could and sometimes do expose them to the public. Could the messages be coming from Alison? But isn’t that impossible? What kind of phone network lets you keep texting when you’re dead? I’d say that’s beyond 4g. It’s one thing to talk with your friends about lacrosse practice or the hot guy in the French class. It’s something else when you’re trying to figure out what happened to your disappeared friend, and how disappeared she really is. â€Å"Pretty Little Liars† is good at making us care about the girl’s lives. It keeps us thinking each week as to what might happen the next.

Changing the Culture at British Airways

Changing the Culture at British Airways 1. Problems you identified from the case Macro: The first problem changing the culture at British Airways was the merger of the BOAC and BEA. In 1971, the Civil Aviation Act became law and the board was to control policy over British Airways but both BOAC and BEA remained autonomous, each with its own chairman, board, and chief executive. This caused a split within British Airways throughout the 1970s and in the mid-1980. The second problem BA faced was the threat of privatization. In 1984 the government passed legislation that made BA a public limited company.The third was productivity was bad compared to other leading foreign airlines. The fourth was poor service. Poor customer service to the employees and customers led to reduced passenger numbers and high fuel costs. This created a reduction in profit (Jick & Peiperl, 2011, pp. 25-29). Micro: The first problem BA had that is not obvious was the change in the organization and culture. There need to be a more institutionalize change. New culture fosters a strong commitment to service. Also, the lack of unity and loyalty caused the airline to not be focused. There was a lack of recognition.This caused a lack of unifying corporate culture. Also, training needs for managers were needed. Organizations need to change to adapt to the changes inside and outside the organizations (Jick & Peiperl, 2011, pp. 28-35) 2. Causes BA will have these problems because they merge two companies with very different style of management, government regulations. They lost millions because of the mindset the management had which questioned why the need for change if we’re making a profit. The lost was great also because people were operating effectively and not efficiently.They believe that if you’re providing service at no cost to taxpayers then you’re doing well and the cost of paying a high price for advance technologies. There was not enough management time devoted to m anaging the changing environment because it was all focused inwardly on resolving industrial relations problems, on resolving organizational conflicts. Both companies had done its share of pioneering. BA needs to be reorganized to have shared desires. This resulted in a financial crises and downsizing of employees (Jick & Peiperl, 2011, p. 35). 3.Organizational Systems Affected Structural: The Leadership indicated that BEA was concerned with building an airline infrastructure than it did in profit. This was reflection a de-centralized leadership style and BOAC was concerned with the jet airliner which was focusing on the task. The merger caused BA to be very controlled with a lot of rules and regulations. Privatization by the British government made BA a public limited company. (Jick & Peiperl, 2011, pp. 26, 34). Psychosocial: Employees expressed their pleasure on being treated with respect.When the merger took place, both BEA and BOAC will have to be loyal to each other and unite. A greater challenge is to change the mindset of employees at all levels. The mindset is a shared way of thinking and behavior within in an organization. They are reflected in accepted behaviors and attitudes. The mindset becomes very powerful in gaining unity and focus within the organization. It provides a common focus and increases the intensity of the work being done (Jick & Peiperl, 2011, p. 39). Technical: BA will have to cut cost and drive customer service.The technological innovation plays and important role. If everyone works together there would be a more cohesive environment and the ability to manage change. When other airlines were not considered and competition was not a factor, BA was successful economically but there were no satisfaction with customer service (Jick & Peiperl, 2011, p. 26). BA need to encourage workshops was great within the organization, having done this customer assessment of the competitors allowed the employees from thinking more about the internal company policies and practices and more time interacting with the customers.Customer may become involved in product design. The more interaction between the customer and employees, the more a customer views is reflected on the organization (Jick & Peiperl, 2011, pp. 40-41). Managerial: BA Managers would have to be very proactive and have a need for change. They made Lord King the Chairman in 1981 and he recognized that a major cooperate change was needed. The leaders at BA must manage through principles. A change was needed in the culture. The leader must articulate and communicate the principles to be successful (Jick & Peiperl, 2011, p. 9). Goals and Values: The BA would have to have contribute to its customers, investors encourage a shared vision and values, enable employees to act by encouraging greater cutomer and cost consciousness, adaptability initiative, accountability, and teamwork. To accomplish these goals, managers will have to model the way (Jick & Peiperl, 2011, p. 50 ). 4. Alternative Solutions One alternative solution to changing the culture at BA is to not resist the change and take an untraditional approach.The greatest effort would be overcoming the mindset of employees at all levels of an organization. Another alternative is managers don’t have to micro-manage. It creates a negative environment. BA focus was primarily on cutting cost and driving customer service. This is a difficult challenge. BA would have been more successful if they would have put the people before the task (Jick & Peiperl, 2011, p. 39). 5. Recommendations and Implementation Plans BA needs to change to adapt to the changing internal and external environment through a restructuring of their organization.They should start out there merger with a vision statement and uniting as one complete team. They need to move with the times, out with the old and in with the new. With the globalizations and technology, organizations have moved from mechanical to a gradual approac h. The mindset of the employees at all levels of the organization need to be changed. BA also needs to analyze their organization through the eyes of the customer perspective. The more interaction between customers and employees the more a customer perspective is instilled within the organization.There need to be work-groups such as self-manage work teams. BA needs to be reflexive and learn from their past (Jick & Peiperl, 2011, p. 42). Training needs to be implemented. There must me a willingness to change for all employees and managers. BA will have the ability to become re-energized and meet the needs of the customers through innovation and being resourceful (Jick & Peiperl, 2011, p. 50). References Jick, T. D. , & Peiperl, M. A.

Dressed to Impress Choose the Perfect College Interview Outfit

Dressed to Impress Choose the Perfect College Interview Outfit Imagine the most delicious donut you’ve ever tasted: Light, fluffy, and just a touch of cinnamon sugar. Now, imagine that someone punches your donut in the face. Does it still taste good? Who knows. It looks so bad that many people wouldn’t even attempt to eat it. College interviews are the same way, except without the face-punching. The way you present yourself is just as important as what you say and who you are as a person. Remember, your college recruiter has very little time to decide if you’re a good fit for their school. That means you need to make a great impression quickly – one that says you are exactly the kind of student they want, both inside and out. Here are the 5 simple secrets of picking the perfect outfit. KISS for Your Interview KISS is an acronym for Keep It Simple Stupid. Make sure that you don’t scare your interviewer off with wild colors, accessories, or piercings. The simpler your attire is, the more likely it is to make a positive impression. No stilettos or cleavage-revealing club tops. No gigantic Mohawk or spiked throat collars. Choose an outfit that is professional but still reflects a little bit of your personality. Color Is King A study by Harris Interactive showed that most job recruiters both consciously and subconsciously note the colors you pick for your interview outfit. Since getting into college is now your full-time job, consider their findings: Job recruiters suggest wearing blue 23% of the time and black 15% of the time. Still, you don’t want to be lost in a sea of monochromatic sameness. Consider choosing a color that fits your school’s ideal student. If you are applying for law school, black, grey, and white might be good colors. For a theatrical program, brown and green might be a good fit. According to color psychology each color has its meaning so you may choose the colors of your outfit according to the impression you want to create: Black – Leadership Blue – Team Player Gray Logical/Analytical White – Organized Brown – Dependable Red – Power Green, Yellow, Purple – Creative Orange – Unconventional/Unprofessional Be Wise, Accessorize Now, we’re not saying that you should look like your Great Aunt Judy (three sets of earrings, two scarves, and a bedazzled Christmas sweater), but consider a tactful and interesting accessory to wear during your interview. A small, personal bit of jewelry like a ring or tie tack is a great way to show your personality without overwhelming your interviewer. Also, steer clear of inappropriate accessories like sunglasses, hats, and gaudy belts or belt buckles that might make you look unprofessional. The Secret’s in the Smell In a recent study of Le Moyne College, researchers proved that how a person smells affects the first impression they make at the interview. And, an additional study from La Salle University showed that a slight floral fragrance leads to more positive interactions between strangers. Needless to say, taking a shower and using a fresh-smelling deodorant is a must for a good college interview. That being said, too much scent can have the opposite effect. Not only can it overwhelm people in the room, but can set off scent allergies. No one wants to be remembered as the person who sent the recruiter into anaphylactic shock. The Taboo List Although many people know exactly what â€Å"business professional† means, there are many who don’t. There are several things that, may immediately cross you off the list. Here are the biggest outfit liabilities for your college interview: For Ladies Nails longer than 1 inch Huge or gaudy earrings Overly-teased hair High heels over 2 inches Colored or patterned stockings Frills or ruffles Skirts more than 2 inches above the knee Shirts that reveal cleavage or stomach area All piercings except a single pair of earrings Clothing that shows tattoos For Gentlemen Sagging pants Mohawks or other unconventional hair styles Unbuttoned shirts Novelty or leather ties/bolo ties Sneakers White socks with dark dress pants – black only T-shirts Piercings of any kind Clothing that shows tattoos Jeans Remember that you dress to impress interviewers, not some party people. Your outfit canl open the doors of prestigious colleges for you, so take it serious. What is more, you will get more chances to prove that your personality is just as reliable, interesting and respectable, as your appearance is.

Hypoglycemia Essays - Diabetes, RTT, Medical Emergencies

Hypoglycemia Essays - Diabetes, RTT, Medical Emergencies Hypoglycemia subject = Human Anatomy title = Hypoglycemia Hypoglycemia means low blood sugar or low fuel in the blood. It also refers to a distubed carbohydrate metabolism, since some people change between high and low blood sugar levels. When the body tries to work under these conditions, mental processes are impaired and body systems are broken. Hypoglycemia is sometimes related to other conditions like drug addiction, alcoholism, allergies, arthritis, diabetes, mental illness, anti-social behavio, an juvenile deliquency. There are numerous causes of hypoglycemia including; inborn errors of metabolism, defects in enzyme systsms, disorders of various glands and organs (hypothalamus, pituitary and adrenals, nervous system, kidneys, and liver). The most common cause is a diet high in carbohydrates and caffiend, which disturbs the blood-sugar regulating systems of the body. THere are a number of symptoms of Hypoglycemia that can be identified. The major symptoms are depression, insomnia, irritability, lack of concentration, crying spells, phobias, forgetfulness, confusion, unsocial or anti-social behavior and suicidal tendencies. The early symptoms of hypoglycemia are similar to those which occur as the result of experiencing a sudden and violent fear: fainting, tremulousness, and inward tremblind, emotional disturbances, chilliness, numbness and pallor encirling th nmouth, hunger, apprehencion, hand tremors, mild degree ofmental cloudiness, dilated pupils and pale skin. As the hypoglycemia progress, a variety of symptoms occur such as headaches, difficulty inconcentration, disoreientation, mental confusion, dizziness, faintness, double vision, coldness of the extremities, staggering or inability to walk, muscle twitching, depression, restlessness, and excessive excitement. Unless these symptoms are recognized and treated, hypoglcemia can lead to convulsions, amnesia, and unconciousness. In 1924, Seale Harris M.D., a diabetic specialist noticed that many peopl had symptoms without having diaetes. Their blood sugar would drop too low after eating a sugary refined carbohyudrate meal, or after drinking cafeine or alcohol. After an initial rise but not into the diabetic range, their blood sugar would then fall into a hypoglemic range with many different symptoms depending on the indivvidual, the immune system, and the metabolis. He was the first person to notice Hypoglycemia and to differentiate it from Diabetes. Hypoglycemia can be treated a umber of ways. THe diet should exclude things that can cause stress on thebody, such as caffeine, nicotine, alcohol, and rapidly absorbed carbohudrates such as sugars, honey, and many grains and cereals. Frequent feedings are essential,k withhearty breakfasts and bedtime snacks. Many symptoms will dissapear when the blood sugar is stablilized. THe most important thing to remember is that the average adult has between one and twot easpoons of blood sugar circulating in his body at one time, with a small amount stored in his liver foremergencies. A child has less in relationto its height and weitht. Eating foods such as 4 ozs of chocolate cake withicing and 6 ozs of Coke, which is too quickly absorbed into the blood, can cause a mess from the sugar overload as the body has to bring the blood sugar down to a normal range by a very complicated process.

The Rock Cycle Essay Example | Topics and Well Written Essays - 250 words

The Rock Cycle - Essay Example The rock cycle is a way of representing the relationship among the three main types of rocks namely sedimentary, igneous and metamorphic rocks. The rocks undergo a constant gradual transition from one form to another. The transitions depend on the physical conditions around them. This paper discusses the cycle and the way in which the rocks change from one form to the other.  The rock cycle is a way of representing the relationship among the three main types of rocks namely sedimentary, igneous and metamorphic rocks. The rocks undergo a constant gradual transition from one form to another. The transitions depend on the physical conditions around them. This paper discusses the cycle and the way in which the rocks change from one form to the other.  Under the earth surface, the conditions available do not allow the rocks to exist in their solid state. Instead, they exist as magma that is a hot liquid. As the magma moves upwards, cooling takes place, and it finally solidifies to for m the igneous rocks. Some of the magma under pressure during the process of volcanicity moves out as lava on the earth surface. The result is volcanic rocks, which are of fine grains (Mattern, 2005).   On the earth surface, igneous rocks undergo the process of weathering since their components do not stabilize at the surface conditions. Moving water and wind are the main factors of weathering. The rocks are broken down to pieces or sediments and carried away mixing up with other components. After quite a long duration of time, the sediments are finally glued together to form sedimentary rocks (Mattern, 2005). Exposing the rocks to high temperature and pressure on the earth surface causes a physical change on them. The high temperature cause hardening of large masses of rocks called metamorphic rocks. The metamorphic rocks are responsible for forming Mountains. Both the metamorphic and sedimentary rocks can melt again to form magma under high temperature. Weathering occurs again on metamorphic rocks, resulting to the formation of sedimentary rocks. The rock cycle starts over continuously (Mattern, 2005).

Visual Analysis and critical reflection Research Paper

Visual Analysis and critical reflection - Research Paper Example At the age of 16 he won a street painting competition that he entered into. He believes he is an autodidact who learns by doing. He has studied the techniques of old masters of street painting and started to make it his profession. Today he is a street painter and does not paint conventionally anymore. His early paintings led him to the title ‘maestro madonnari’ which means master street painter, and these paintings were mostly two-dimensional. As the street art developed, the three dimensional paintings came into effect. Muller first painted in 3D on a client’s car. He was eventually inspired by the ideas of Julian Beever and Kurt Wenner. He started painting illusion in 3D street paintings and his skills and drawing techniques made him the best in the world (WebUrbanist, 2013). Lava burst (Bored Panda, 2013) Mueller uses the street as his canvas and literally involves the viewers to the imagery. He uses hundreds of square meters of the pavement and paints to chal lenge the perceptions of the street walkers. This 3D painting of a lava burst was painted by Mueller on the 30th anniversary of international competition of street painters held in Geldern, Germany. He painted a large sized picture once more and created scenery which appeared apocalyptic. Mueller was 25 years old when he had given his entire life to street painting. He made several paintings all around Europe and aimed to earn through the transitory art. He became an organizer and committee member for street painting festivals and also set up the Internet board for street painters of Germany. This was a forum which promoted the solidarity amongst the various German street painters. He also presented the master works of old painters to people in his studio and drew perfect copied of those paintings. With the help of the old painters’ works, Mueller helped the ones interested in paintings to understand the depth of the art. Ice Age (Bored Panda, 2013) This is one of the best wo rks of Mueller and was completed in 5 days. It is a huge picture of the ice age and shows creative illusion. He needed about five assistants who helped him all day long in painting the huge painting. The illusion was painted by the application of the anamorphic technique to the huge pavement. The picture is approximately 250 square meters large. This was the most challenging painting made by Mueller and it was created for the Festival of World Culture in Ireland (2008). This painting was the most challenging one for Mueller because of the weather conditions of Ireland. Ireland’s weather often fluctuates and usually there are four seasons felt in one day. Sunshine, hailstorm and rain all were experienced within few hours. Mueller and his team of assistants did not think that they would get through with the painting, but they accepted the challenge and completed it. The street painters often face the difficulties with coping with weather conditions because all of their work is out on the streets. Rain is usually the biggest element to fight as the use of paints and chalks is done for these paintings. If the rain spoiled the painting overnight, Mueller would usually start a new one. Hence the weather issues are not a problem for Mueller as he says â€Å"once a painting is done, I somehow lose interest in it. It’s done and for me it is up to go for the next† (WebUrbanist, 2013). Gradually the changing trends have also redirected the interest of Mueller in his paintings. Thus he has
