Definition of the Term LD50

Definition: The median lethal dose of a substance, or the amount required to kill 50% of a given test population. LD50 is a measurement used in toxicology studies to determine the potential impact of toxic substances on different types of organisms. It provides an objective measure to compare and rank the toxicity of substances. The LD50 measurement is usually expressed as the amount of toxin per kilogram or pound of body weight. When comparing LD50 values, a lower value is regarded as more toxic, as it means a smaller amount of the toxin is required to cause death. The LD50 test involves exposing a population of test animals, typically mice, rabbits, guinea pigs, or even larger animals such as dogs, to the toxin in question. The toxins might be introduced orally, through injection, or inhaled. Because this testing kills a large sample of the animals, it is now being phased out in the United States and some other countries in favor of newer, less lethal methods. Pesticide studies involve LD50 testing, usually on rats or mice and on dogs. Insect and spider venoms can also be compared using LD50 measurements, to determine which venoms are the most deadly to a given population of organisms. Â   Examples: LD50 values of insect venom for mice: Honey bee, Apis mellifera - LD50 2.8 mg per kg of body weightYellowjacket, Vespula squamosa - LD50 3.5 mg per kg of body weight Reference: W.L.

Sigmund Freud s Theory Of Psychoanalysis Essay - 1691 Words

Freud’s theological perspective was termed Psychoanalysis. Freud believed people unconsciously repressed information, and that this hidden information was the cause of their distress. The unconscious is the space in your brain where thoughts, feelings, and desires are tucked away, and cannot be readily drawn upon and available to the conscious mind. Because 99% of this methodology is dealing with the unconscious, Freud believed that success could not be reached by the individual alone, rather they need someone trained in the ways of Psychoanalysis to help them. In contrast, the conscious mind is all of the things we are thinking and feeling now; it is information that is easily accessible to us. There is also this idea of a preconscious, where while we are not currently thinking of that information, if we want it, it is there and can be pulled up when we are ready to attend to it. Psychotherapy was often a many year process where various methods and theories within his theory of Psychoanalysis were considered and practiced. One of these theories is that of psychosexual development. Psychosexual Development As one grows and develops it is often times clear they pass through difference stages of development; for Freud, his focus was psychosexual development. This term refers to how sexual energy, libido, is found and focused on different parts of the body throughout development.

Preventive Stress Management in Organizations †MyAssignmenthelp

Question: Discuss about the Preventive Stress Management in Organizations. Answer: Introduction Team work vs. individualism is a concept that has been in work contention over a long period of time. The concept of individualism is a political, psychological and ethical concept that delves deeper into a human or workers character traits. From the psychological and the ethical point of view, individualism gives a human being the make decisions independently while following his own independent and free thinking. It is strongly linked to individual rights supremacy in political spheres (Biech, 2008). Personal success is greatly highlighted by companies that push for individualism rather than teamwork or collective success. It requires high levels of individual responsibility and following of personal initiatives. A closer in the operations of Australias largest company that is BHP Billiton in leadership and management as teamwork which has led to the success of the company. In BHP Billiton organization, it is important that employees work as a team. Every employee must contribute hi s bit to make team work the best results. When working in a team effectively, synergy appears, that is, the union of energies. This causes the efforts made by the members to be strengthened, reducing the time of action and increasing the efficiency in the results (Dalton, Hoyle and Watts, 2006). Teamwork and its many advantages Today, when conducting a job interview, this competition (teamwork) is one of the most highly rated by recruiters in staff selection processes, as it brings many benefits to the company. Here are some benefits of teamwork: Individual work increases the workload and responsibilities and this can lead to increased stress. Since teamwork allows both tasks and responsibilities to be shared, stress decreases. Since teamwork allows individuals to focus on what they do best, they do not have to worry about jobs or tasks they do not master. This helps to produce better quality work, since it increases productivity. Each individual focuses on their specialty, and collaboration allows each to maximize their potential in the dominating task. Before achieving results, teamwork needs a period in which interpersonal relationships are established. Groups that go forward increase efficiency and productivity (DuBrin, 2009). If a company wants teamwork to bring the benefits mentioned above, it is necessary for employees to work as a whole. For good teamwork, you should: Build trust Set common goals Create sense of belonging Involve people in decision-making Seek understanding between parties Encourage communication Seize diversity Celebrate group successes Promote mutual commitment and shared responsibility If BHP Billiton has talents in different facets and you put them to work each one separately, you will not be able to create the necessary synergies. Therefore, give the team strength a chance over individualism and you will notice how the dynamics improves It is true that the working groups in the organizations bring positive results, but in order for them to function correctly, and achieve the objectives satisfactorily, they need some kind of organization, but there is a risk that some of the disadvantages of group work will be fulfilled (Miller, 2007). This is where the dynamics of teamwork come into play, because if we manage to find the right ones, we will achieve all this advantages when working as a team: Better ideas and decisions that lead to higher quality results, as there are more minds working on it and supervising the work at the same time.It encourages collaboration and increases trust and solidarity among colleagues, resulting in greater happiness at work. Multifunctional skills are growing. Communication is extended, leading to better understanding and better management of equipment. Examples of Teamwork versus Individual The working environment also benefits because the individual objectives are surpassed by the groups. A good working team with the right dynamics will be able to put the interests of the group above the personal ones.The acceptance of ideas and decisions will be better with group work than if they come from a single person, since it no longer sounds to impositions but to proposals and they lead to a mutual consensus. In BHP Billiton, departmental heads are leaders while the casuals and the engineers work under them to produce quality products. Individual trust is greater thanks to the support of the group, as it creates a climate of security with shared responsibilities that allows more confidence in one's own possibilities, while individual weaknesses are more compensated. Authority and autonomy can be delegated, while in individual work no. Increases the speed of work, since the processes of corrections and control are reduced more than in a vertical organization In the abstract, t here is no ideal team. Taking a number of people, all of them exceptional professionals and putting them to work together does not guarantee that you will be an exceptional team (Quick, Wright and Adkins, 2015). This is because it is the most efficient way, and because the first swords, the exceptional people, are bright stars, they must shine alone and not within a constellation. Each company has some goals to achieve, these vary from company to company, even within a single structure the goals change at every moment. The ideal team, for a given company at a given time, is the one that is the most adequate to achieve its objectives in the most efficient way, within the environment in which it is. It is even presumed to work as a team as if it were a personal virtue and the panacea to solve all problems (Salas, 2013). In our experience, not everything that qualifies as teamwork is actually. In fact, teamwork is not given when many people work in the same and compete with each other; They avoid the responsibilities that they must assume, passing the affairs of one to another; They defend enclosed stumps; When a homogeneity in people is forced to "adapt" to the leader. There are things that must be done alone, for example: think, decide, take responsibility, some activities that require a special concentration, review of own actions, leadership. However, the complexity of many tasks and issues imply that they are unreachable by a single person, and need to be done for more (Salas, 2013). Teamwork is neither more nor less than the individual work that collaborates towards a common end. It is an attitude of service towards a spirit of the hive: a super organizational end. All members of the team voluntarily decide to subordinate part of their freedom (and particular interests) to a maximum goal: to tr uly work as a team. That is, teamwork becomes an end in itself, because the members of the team are convinced that it is the best way to achieve the end of the project. Conclusion This is always done in a conscious respect for the dignity of individuals and particular interests. Value added, wealth comes from the diversity of what each is and brings.All papers in principle have the same value. The leader is not the most important: he is simply the leader. Applying to the world of work, this principle came to a conception of human nature that can be summarized as "that men feel disgust for work by the effort and responsibility it entails (Simpson, 2017).If they work, it is to obtain a salary (economic incentives) that allow them to satisfy certain needs in the margin of work. As they are passive and lack interest in their work, men must be directed and require strict control of their behavior. Therefore, it is an economic motivation that pushes men to work.

Steps free essay sample

Fourteen people climbing 4,000 feet. One step after another. Four hours and still hiking. Another step, another breath. Amidst the dizziness and the heat, I can barely make out the top of Table Rock. It seems as if we are only getting farther away. In front, three young cousins sprint ahead, laughing, skipping. Yet, here I am, at the end of the line, trudging up ever so slowly. With another step, my mind rewinds to the previous year. I am looking at a test with red marks splattered across it: my first failing grade. I glance around and see others smiling as they tuck their papers away. I had studied. Studied hard. The bell rings and students begin to file out of the classroom. Should I go talk to the teacher? I can’t. I had never talked to a teacher about a failing grade. I was a good student, a smart kid.

Another step. Sweat is beginning to drip. Take a drink. I squint and see our destination. I can still cover the whole rock with my thumb. I keep trudging. I’m sitting in the car, refusing to come out. My mom is gently motioning from outside to open the door. I glance in the mirror above the windshield. My face is a swollen, blistered, oozing mess. I quickly shut my eyes and turn away. My team is already warming up, getting ready for the big championship game. One case of poison ivy, no matter how severe, doesn’t justify missing it. I take a deep breath, clench the door handle and step into the light. Step, breathe, step. Almost there. Maybe another hour left. I am on stage: a dance recital. The bright lights shine on us, highlighting our every move. The music flows and we flow with it. Suddenly we freeze. The next step? We turn to each other, panic rising in our chests. The next step? No more steps to the top. Time to climb. I reach out and grip the rocks. My muscles contract as a stream of sweat trickles down my hairline. I have had no tragic, heart-rending circumstance, no life-threatening obstacle to overcome. To the world, my obstacles may seem insignificant, yet to me they are mountains. Mountains, large and small, which I have conquered. Mountains stand in the background of where I have been. Mountains remind me where I am going. I clutch the rocks and pull myself to the top. I catch my breath and gaze across the valley. The clouds are almost at my reach and I can see the world.

Emailing a Literary Agent

Emailing a Literary Agent Emailing a Literary Agent Emailing a Literary Agent By Maeve Maddox In the old days writers could send out their queries and fantasize for weeks about acceptance before getting that crumpled little self-addressed envelope with its bad news back in the mail. Nowadays, thanks to email, we can be zapped with rejection in a matter of minutes! Nevertheless, email queries are a boon to writer and agent. They save time, paper and postage. Not to mention unproductive fantasizing. Much email writing breeds carelessness in most of us so its a good idea to pay special attention to any email we direct to a literary agent. Here are some guidelines. Subject line: Put something meaningful in the subject line. For example, a meaningful subject line for a query about a novel called It Was A Dark and Stormy Night would be Query: It Was A Dark and Stormy Night. Contact information: The usual place in an email for contact information is at the end, after your name. However, in this case its a probably a good idea to let the agent know immediately whose query is unscrolling before him. Just put the same contact information at the top left of the email that you have after your name at the bottom. Greeting: Use the same salutation you would in a letter. Do your homework. Address your query to an individual, not an agency. Find out if the honorific is Mr. or Ms. Avoid Email Speak: Dont pepper your query with abbreviations like BTW or LOL. Think business letter. Write the email as if you were going to mail it the old-fashioned way. Formatting: Keep your email query brief. Avoid long screeds of words. Break it up into short word groupings. I hesitate to say paragraphs. In web writing proper paragraphing is not always an option when the goal is to present easy-to-read clumps of words. And above all, DONT WRITE IN ALL CAPS! Correct spelling and usasge: Most emails are composed on the fly. We open Compose, dash off our message and hit Send. Thats not the way to handle an email query. A single misspelling or misused pronoun can shoot you down with the agent. Write your query in a word processor. Use the spell checker. Run it out and scrutinize the hard copy. When your query is error-free, then and only then paste it into the email and hit Send. Tone and Style: Be businesslike. You can be cordial without being chummy. Dont try to crack a joke. Jokes have a way of coming out all wrong in an email. And as for emoticons. Puhleez! 🙂 Attachments: Unless the agent has asked for an attachment, dont send one. Most people, not just literary agents, maintain a strict policy of not opening attachments from strangers. Links: Given the tiny bit of space allowed by an email to present ourselves, its tempting to want to include links to sites that tell more about us or showcase our writing. Its probably not a good idea. All the agent wants in this first approach is the gist of your proposal and an idea of your professional credentials. By all means, place a link to your professional website after your name at the end of the email, but dont pepper the body of the email with links. The OWL at Purdue offers general guidelines at Email Etiquette. Business managers who would like to draft an email policy guide for their employees will find 32 rules of email etiquette at a site called Emailreplies.com.

In the dictionary, you will see the verb for to try listed as conor, -ari, -atus sum try Conor is the present passive first person singular indicative, but because the verb is deponent, it is translated as if it were active.Conari is the present passive infinitive. Because of the a. you can tell this is a first conjugation verb. Conari is translated as if it were an active infinitive: to try.The third entry in a non-deponent verb is the third principal part, which gives you the perfect active stem. If the verb were laudo, you would seeRemove the i from laud avi and you have the perfect stem. There is none in the case of conor, because in deponent verbs, the third principal part is skipped.laudo, -are, -avi, - atus praiseConatus sum is the perfect passive participle plus the first person of the verb for to be. In a non-deponent verb, this form would give you the perfect passive, but here the form gives you the perfect active: I tried.

American Airlines vs. Southwest Term Paper Example | Topics and Well Written Essays - 1500 words

American Airlines vs. Southwest - Term Paper Example As the report declares Southwest is found to be continually winning over American Airlines in terms of economies of scale. American Airlines is fast losing upon its consumer base which has compelled it to operate over a lower scale compared to its low cost rival. Economies of scale imply the accrual of profit over the long run on account of an expansion in the scale of operation. This paper stresses that LRAC is a combination of a large number of short run average cost curves which too assume a similar U-shape. However, their minimum point continues to shift lower and the LRAC is the locus of the minimum points of all these short run average cost curves. Normally, a company does not continue its production operations after having reached the point of minimum long run average cost. This is the reason why the long run average cost curve is often held similar to the supply curve of the concerned producer. He will generally produce at the point where his short run average cost is lowest and thus, when the loci of all those points are obtained, it yields the long run supply curve of the organization concerned. In the present case, the situation could be interpreted as follows. Southwest Airlines has been growing in size on account of an expansion in its customer base and its average cost of operation over the long run is being reduced simultaneously as well. Howev er, the situation is found to be quite different for American Airlines, which although has a prospect of operating over the large scale, cannot do so on account of a reduction in its customer base. ... The fall in the cost of production has been interpreted as long run average cost (LRAC). Actually, LRAC is a combination of a large number of short run average cost curves which too assume a similar U-shape. However, their minimum point continues to shift lower and the LRAC is the locus of the minimum points of all these short run average cost curves. Normally, a company does not continue its production operations after having reached the point of minimum long run average cost. This is the reason why the long run average cost curve is often held similar to the supply curve of the concerned producer. He will generally produce at the point where his short run average cost is lowest and thus, when the loci of all those points are obtained, it yields the long run supply curve of the organization concerned (McEachern, 2011). In the present case, the situation could be interpreted as follows. Southwest Airlines has been growing in size on account of an expansion in its customer base and it s average cost of operation over the long run is being reduced simultaneously as well. However, the situation is found to be quite different for American Airlines, which although has a prospect of operating over the large scale, cannot do so on account of a reduction in its customer base. A reduction in average cost accompanied by a hike in production implies the incurrence of higher profit margins as well. This could be well evinced through the fact that during the first quarter of 2009, Southwest Airlines reaped a profit of nearly USD 5 million while its passenger base increased by approximately 12 percent. Over the same period, American Airlines incurred a huge loss and its passenger traffic expanded by a nominal 1.6 percent (CBS News, ‘Airline

Situational Analysis - Obamas Inaugural Speech - Essay Example He gives hope for the dwindling economic throttle hold which has seen the deterioration of health, education, business, and employment sector as a result of greed, the irresponsibility of a few and the collective failure to make hard choices. To tackle the war, President Obama promises that America will responsibly withdraw its forces from Iraq and also â€Å"forge a hard-earned peace in Afghanistan† and to work tirelessly with â€Å"old friends and former foes to lessen the nuclear threat, and roll back the specter of a warming planet†. Obama, the first African American president, is addressing an audience drawn from all races at a time when the whole world is experiencing economic problems or war of a kind. The words must be well selected so as to appeal and put insight into the audience but not to provoke hard feelings from â€Å"old friends and former foes.† He must also bear in mind the millions of non-Americans listening to his speech, anxiously waiting for his remarks on the nuclear menace and war at large. America being the superpower and being at the watch by the world, his speech has to be well articulated. He has to tackle for instance terrorism and religious schisms well, in an attempt to unite the world once more. He does this by speaking directly to the people, the Muslim world, current leadership around the world, poor nations as well as prosperous nations. Being an African American, he has to address the issue of racism well, as this vice previously blackened the American History.

Advocates violence Essay Example for Free

Advocates violence Essay A hate group is â€Å"a group or movement that advocates violence against or unreasonable hate or hostility toward those persons or organizations identified by their religion, race, national origin, gender, sexual orientation, or disability† (Wikipedia, 2004). The ideology of hate groups is based on the inaccurate information using for disparagement. The members of hate groups prejudge each individual in the target group as low or contemptible. They believe in the supremacy of their race, religion and use the violence and intimidation as the tools of the infuence on the target groups. How they do it? Usual tactics of the hate group includes four main elements: dehumanizing or demonizing the target; use of the conspiracy, theories, possibly not well backed up or referenced; claiming for manifesting interests of majority, support of thef pseudo-scientific theories using as the background for their grudge against target groups. The Southern Poverty Law Centers Intelligence Project reckoned up that 751 hate groups were active in the United States in 2003 (http://www. tolerance. org/maps/hate/state. jsp? T=12m=2). The most infamous and oldest American hate group is the Ku Klux Klan. This movement joined more than 150 various hate groups. The target of the attacks of the Ku Klux Klan is blacks, Jews, immigrants and gays. Today the most active Ku Klux Klan organization in the USA is the Church of the American Knights of the KKK. This radical wing of the Ku Klux Klun is led by Jeff Berry and had strong prositions among other hate groups of the state of Indiana. While other KKK groups are trying to represent themselves as a civic organization for whites, the American Knights actively propagate strong measures against minorities. The credo of the American Knights is expressed in Jeff Berry’s speech: â€Å"We hate Jews, We hate niggers†¦. I’m a Yankee and I have never heard the word thank you in the nigger vocabulary†¦. We don’t like you niggers†¦ Tell me one thing your race has accomplished. † (ADL audio tape of Jasper rally, October, 1998 rally in Jasper, TX cited by http://www. adl. org/backgrounders/american_knights_kkk. asp). The same ideas we see in the Platform of the American Knights: Enemies from within are destroying the United States of America. An unholy coalition of anti-White, anti-Christian liberals, socialists, feminists, homosexuals, jews [sic] and militant blacks have managed to seize control of our government and mass media. This gang of criminals and degenerates has declared war on the hard working, tax paying, White citizens †¦ The American Knights of the Ku Klux Klan plan to change things for the better. We shall liberate our nation from these savage criminals and restore law and order to America. (cited by ADL backgrounder, 1999) But the hate groups do not only tell terrible words. They also do the terrible things. Every hour in the USA someone commits a hate crime. Every day at least eight blacks, three whites, three gays, three Jews and one Latino become hate crime victims. Every week a cross is burned. Three crosses were burned in the yard of a mixed-race family in the March of 2003 (Ladoga, IN). Swastikas and offensive messages were burned into the lawns of four residences (St. John, IN). The Knights of the Ku Klux Klan distribute their flyers throughout a neighborhood. According to FBI statistic â€Å"the greatest growth in hate crimes in recent years is against Asian Americans and gays and lesbians† (http://www. tolerance. org/pdf/ten_ways. pdf). But the noble Knights of KKK do their business only with hidden faces: â€Å"It is essential to the organization to allow members to preserve their anonymity since, if members are not allowed to appear in public without being able to maintain their anonymity, they will not participate in public events† http://en.wikipedia.org/wiki/Hate_group

Managed Care :: Caregiver Medical Health Care

The advantages of managed care to the consumer are medical expenses completely covered, no deductible, and lower monthly premium payment. The consumer under managed care coverage would only need to make his monthly premium payment and co- payments. Managed care makes health care more affordable to the consumers. The disadvantages of managed care would be the consumer would only be able to see caregivers affiliated with the managed care organization, having to pay co-pay every visit, rising premiums, under treatment, and too much reed tape to get necessary treatments. A caregiver’s perspective about managed care is it offers some stability in patient load and income. Managed care would help cut some of the caregiver’s expenses of maintaining facilities and staff, by uniting caregivers and sharing resources. Managed care may also help health care organizations run more efficiently and effectively. The disadvantage is a loss of professional independence and, an increase financial risk. According to the text â€Å"Capitation is especially risky because providers receive a set fee no matter how much care is needed.† A great deal of vigor in managed care is focused on paperwork, authorizations, and procedures, and caregivers say it is nearly unattainable to do their jobs efficiently and meet the increased demand for paperwork. Which would I prefer traditional insurance or manage care? Well this is a very tough question for me. I have had both, when traditional insurance was on the rise during the late 90’s, my ex-husband and I had very affordable insurance for a very reasonable price. We had no deductable, we could see who we wanted for caregivers, a ten dollar co-pay, and reduced prescriptions. Today I am on Medicaid (not for elderly but for poor), but I don’t think I could afford today’s insurance prices. I like Medicaid because I don’t have to worry about money for doctor’s bills, co-pays, or prescriptions. On the other hand I have a tough time finding caregivers accepting new Medicaid patients, some doctors treat Medicaid patients differently, many treatments and prescriptions ordered are not covered by Medicaid, so I had to go with out.

Health Paper-Hypertension Essay

Hypertension also known as high blood pressure is a common condition in which the force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease. Blood pressure is determined by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure. High blood pressure is the leading cause of stroke and a major cause of heart attack. In the U.S alone, more than 30% of American adults have high blood pressure. Hypertension is often called the â€Å"the silent killer† because it rarely caauses symptoms, even as it inflicts serious damage to the body. You can have high blood pressure for years without any symptoms. If your blood pressure is uncontrolled it can increase your risk of serious health problems, including heart attack and stroke. High blood pressure develops over many years, and it affects nearly everyone eventually. Although high blood pressure is most common in adults, children may be at risk also. For some children, high blood pressure is caused by problems with the kidneys or heart. But for a growing number of kids, poor lifestyle habits, such as an unhealthy diet and lack of exercise contribute to high blood pressure. Most people with high blood pressure have no signs or symptoms, even if blood pressure readings reach dangerously high levels. Although a few people with early stage high blood pressure may have dull headaches, dizzy spells or a few more nosebleeds than normal, these signs and symptoms typically don’t occur until high blood pressure has reached a severe, even life threatening stage. Thankfully, high blood pressure can be easily detected. Once you know you have it you can work with your doctor in controlling it. There are two types of high blood pressure. First, Primary (essential) hypertension. For most adults, there’s no identifiable cause of high blood pressure. This type of high blood pressure, tends to develop gradually over many years. Second, Seconday hypertension. Some people have high blood pressure caused by an underlying condition. This type of high blood pressure, tends to appear suddenly and cause higher blood pressure than does primary hypertension. Various conditions and medications can lead to secondary hypertension. High blood pressure has many risk factors including: age(the risk of high blood pressure increases as you age), race, family history, being overweight or obese(the more you weigh,the more blood you need to supply oxygen and nutrients you your tissues), not being physically active, using tobacco, using to much salt in your diet(too much salt can cause your body to retain fluid which increases blood pressure), too little potassiium in your diet, too little vitamin D in your diet, drinking alcohol, stress and certain chronic conditions. The excessive pressure on your artery walls caused by high blood pressure can damage your blood vessels, as well as organs in your body. The higher your blood pressure and the longer it goes uncontrolled, the greater the damage. High blood pressure can cause hardening and thickening of the arteries, which can lead to a heart attack, stroke or other complications. Blood pressure is measured with an inflatable arm cuff and pressure measuring gauge. A blood pressure reading, has two numbers. The first, or upper, number measures the pressure in your arteries when your heart beats which is called systolic pressure. The second, or lower, number measures the pressure in your arteries between beats which is called diastolic pressure. There are four general blood pressure measurements. Fist, normal blood pressue. Your blood pressure is normal if it’s below 120/80. However, some doctors recomment 115/75 as a better goal. Once blood pressure rises above 115/75 the risk of cardiovascular disease begins to increase. Second, prehypertension. Prehypertension is a blood pressure measurement of 120/80 to 139/89. Prehypertension tends to get worse over time. Third, Stage 1 hypertension. Stage 1 hypertension is a blood pressure reading ranging from 140/90 to 159/99. Fourth, Stage 2 hypertension. More severe hypertension, stage 2 hypertension is a blood pressure reading of 160/100 or higher. Changing your lifestyle can go a long way torward controlling high blood pressure. But sometimes lifestyle changes aren’t enough. In addition to diet and exercise, your doctor may recommend medication to lower your blood pressure. Which category of medication your doctor prescribes depends on your stage of high blood pressure and weather you also have other medical problems. It’s never too early to make healthy lifestyle changes, such as quitting smoking, eating healthy foods and becoming more physically active. These are primary lines of defense against high blood pressure and its complications.

Thinking Outside The Box Essay

We live in the age of new technologies, in an age of rapid progress and every successful employer seeks to meet all the requirements of the present time namely control and improve the quality of services, to reduce execution time and be the best in the business, despite not less intelligent competitors. 1. What external factors were affecting UPS’s HR practices? How did UPS respond to these trends? Workers of the UPS has a responsible attitude towards the quality of their services. They daily take care about these services, and also prepare highly qualified specialists. One of the problems that they are facing is that a large number of people (baby-boomers) are close to retirement age. UPS has taken steps to be sure that they will have driver which will be ready for meeting the demand. The company staff is hiring and training some 25.000 drivers over the next five year to replace retiring Baby Boomers. Based upon the premise that younger drivers learn best by technology and hands on training, UPS has created several simulations and a videogames designed to aid in driver training. 2. Why is efficiency and safety so important to UPS? What role do the company’s industrial engineers play in how employees do their work? The answer lies in the amount of people and companies with which UPS operates. UPS sends more than 15m parcels in more than 200 countries every day. Because of competition (i.e. the U.S. Postal Service, DHL, and Federal Express), for UPS, it’s all about speed, accuracy, and safety. UPS must keep cost low and customer satisfaction high. To increase the productivity of drivers, UPS has used their industrial engineers to design more efficient routes, loading & unloading procedures, and employee policies to help get the most from their employees in the field. 3. What changes did the company make to its driver training program? In addition to learning the company’s ‘340 Methods,’ applicants play a videogame where they’re in the driver’s seat and must identify obstacles. From computer simulations, they move to â€Å"Clarksville,† a mock  village with miniature houses and faux businesses. There, they drive a real truck and â€Å"must successfully execute five deliveries in 19 minutes.† And, in the interest of safety and efficiency, trainees learn to carefully walk on ice with the slip and fall simulator. 4. What advantages and drawbacks do you see to this training approach for (a) the trainee and (b) the company? It appears that the use of simulations and the other new programs implemented by UPS would have good transfer to work the drivers would be doing in the field. This is an advantage for the trainee and the company. A potential disadvantage would be if the applicant was not familiar with new technology, such as computer games, or other forms of electronic learning. These applicants may be successful in the job, but may not show proficiency in training due to the technological nature of the training. For the company, such programs are expensive but that can be balanced by the benefit of having a better trained workforce.

buy custom Technological Innovation in the World History Before 1500 essay Introduction Technological innovation refers to the vital advancements that take place in various sectors leading to an improvement in performance. The world history has experienced tremendous technological innovations from time immemorial. For instance, the world experienced considerable technological advancements in the agricultural sector with the innovations leading to heavy ploughs. This innovation had considerable cultural implications such as increased consumption due to better ways of production. This paper explicates the heavy plough innovation. My innovation is the heavy plough. This plough promoted efficiency in farming because it had a wheel making it easier for farmers to use (Gies and Gies, 100). It was advanced as the wood parts were replaced with metallic parts, to ensure durability. The innovation of the heavy plough was timely as it addressed the rising food demand among the fast growing populations. The heavy plough is believed to have developed in the Slavic lands. This is because the earlier words describing the plough were in Slavic hence making the region the potential innovation area. The early settlers in the Slavic land were the first to use the plough (Tannenbaum and Dudley, 120). Slavic innovators thought it better advancing the plough and making the workload simpler for the farmers. This innovation happened in the 5th century as there was the urgency to feed the increasing population. The 5th century was a vital period as it leads to increased use of metals in the development of this plough. This meant it could be used to plough heavier soils. This innovation underwent gradual developments. Firstly, simple ploughs with a runner were used. These were mainly made of wood making them lighter and effortless to use. Farmers could adjust them by lifting the runner (Barbier, 110). This made it simpler for them to prepare their farms although only in softer soils. The need for a better and improved plough led to this innovation. The innovators wanted to address the need for efficiency and wider farming in all soils and seasons without strain. Thus, they thought of how to come up with a more improved form of plough (Tannenbaum and Dudley, 122). They developed a plough by replacing the wood made ploughs with iron made ploughs. In addition, they introduced a wheel to replace the runner. This made the plough heavier compared t the initial one hence the name heavy plough. This improved the working of farmers as it could easily plough most soils. The heavy plough innovation is significant for world history. The innovation led to increased food productions. This meant that people all over the world at that time adopted this method of preparing their farms hence making their work simpler. In addition, this innovation is significant to the world history because it led to increase in the population all over the world. The increase in population arising from the innovation is vital to the world history because it helps tell the population compositions in the past and major growth, in the world populations (Smith and Marx, 114). The innovation is significant in the sense that it helps form part of considerable historical stories relating to transformation and development all over the world. The world history can inform people of the major developments in the entire world through this innovation. The innovation is further significant to the world history because it helps trace the adoption of various agricultural methods and tools all over the world. For instance, the innovation helps one to tell how the plough moved from one point of the world to another leading to transformations in the agricultural sector. This is vital to the world history because interrelationships and transfer of technology with various areas is told. In addition, it is significant because it contributes to the contents relating to development of a new world (Smith and Marx, 130). The world history can write various issues arising from the innovation and link them to the modern world where technology is of more advanced nature. The world history is able to tell of the innovators and the regions they came from due to the research and analysis of various matters thus expanding worldwide understanding of the heavy plough and others related to it. The innovation forms a basis for the writing of world history. The early writers were able to develop ideas and cardinal points relating to past agriculture from the innovation. The theories relating to agricultural innovations are based on the innovation making it a landmark topic in the world history. To the current world, this innovation is still significant. It has helped individuals learn from the past innovations hence making them able to develop better and diversified means of innovation. Individuals have been able to learn the art of coming up with new implements for agricultural purposes hence ensuring the menace of hunger is tackled from all sides (Tannenbaum and Dudley, 133). The innovation has enabled the current world to trace the origin of the current farming techniques and technologies hence readily identify with them. For instance, people know how the plough came into place, and the utmost advancements adopted to make it more relevant in agriculture. The current world benefits from the innovation in the sense that there is increased food production. Most people are still using the wheel plough in the preparation of their farms. This ensures that the modern world is getting adequate food just like the past world. The innovation is also contributing to leading research in many parts of the world (Barbier, 123). People still have the urge to come up with ploughs that have wheels just like the heavy plough. This has seen most researchers and innovators coming up with newer means of advancing this heavy plough. The world today can know and explain the past farming habits. This is learnt from the innovation and its impact on past agriculture. Individuals are able to tell how the past world used to practice agriculture and how this was significant. It is able to know how the past world used to gain from the innovation. Smith and Marx (140) assert that this is vital because it helps establish and inform the current world of past events leading to better ideas and adoption of better means. History enables the current world learn on how to better the agricultural practices compared to the past world hence better food security. In conclusion, an innovation refers to the advancement of the existing technology. The innovation relating to the heavy plough was vital. The innovation came up in the 5th century. It came up and adequately addressed the problem of feeding the massively growing population. It was innovated in Slavic lands and further spread to other areas of Europe like Italy. This is so because most of the words describing the plough came from the place. The innovation is vital to the world history. It forms a basis of writing the world history. In addition, it enables the world history tell of the gradual emergence of this vital plough. World history can establish the emergence of agricultural implements and the persona behind them. To the world, the innovation has increased the urge for more detailed innovations and research. The need to get a better form of the heavy plough is the motivation for the research.

Project procurement and contract management Essay

Project procurement and contract management - Essay Example In managing contracts related to procurement of materials in projects the purchasing manager or the specialist has to perform a series of tasks according to some predefined criteria. In the same way the purchasing specialist has to take it to consideration the number of factors that directly and indirectly impact on his performance In the first instant skills of the purchasing specialist would be enhanced by the vertically integrated organizational and management structure which essentially support the design planning and implementation of supply chain strategies, especially those directly related to the purchase of raw material and components for primary operations.The purchasing specialist has to focus on his tasks associated with procurement and management in order to achieve a degree of functional conformance to established standards such as the core business activity related efficiencies. This means that the ever increasing practice of modern business organizations' preference f or outsourcing certain tasks that lie out of the core business functions of the organization is dictated by competitive pressures. For instance the purchasing specialist would be able to hone his skills depending on the level of concentration on core business operations by the company.Business organizations’ increasing level of dependency on resources procured from outside enables purchasing specialists to develop a special set of skills for effective practice as a purchasing specialist. ... Customer relations and strategic focus on facilitating the control over internal and external relations are much more important than the activity of selling. As such the purchasing specialist's functional skills are augmented by both complexity and diversity of the facilitator's role rather than putting the purchasing manager or specialist into and old fashioned functionary's mould. The purchasing specialists would have to place emphasis on the supplier's credentials rather than the price itself. In the first instance a competitive tendering process involves not only specification and evaluation criteria but also the painful task of selecting the best team for the tasking hand (Morris & Morris, 2007). This requires not only a knowledge of tendering skills but also particularly strong evaluation techniques. This is due to the fact that value parameters attached to the determination process of suitability criteria are fundamentally based on the purchasing specialist's dynamic role. The entire process of procurement of supplies has to be specified in conformance with the cost involved in the prolonged lifecycle of the product. The purchasing specialist has to plan for the appropriate evaluation criteria, that would otherwise be ignored and delivery schedules dragged without much consideration of the critical path (CPA). This might affect both the functional paramet ers and the technical specifications, thus hindering the aesthetic and qualitative outcomes of the process. Finally the purchasing specialist needs to focus attention on the objective of controlling the entire supply chain evaluation process in a manner that non price factors receive a fair share of attention throughout the tender process, thus leaving little room for any

How to Write a Poem About Lacrosse Essay Example for Free

How to Write a Poem About Lacrosse Essay The general purpose of this speech is to demonstrate. The specific purpose is to show how to shoot a lacrosse ball, catch a lacrosse ball and cradle the lacrosse ball. I am going to show you the proper way to shoot the ball, the right way to catch the ball and the correct way cradle the ball. Everyone chill-lax, i’m going to tell you about lax. I am the best person to give this speech because I have played lacrosse almost all my life and I am very good at it. This demonstration will be useful to you because if you ever want to try lacrosse, you will know some of the basics. The first part of lacrosse I am going to tell you about is how to shoot the ball. There are three main points on how to shoot the lax ball. The first is to keep your elbows and hands out and away because you can get more power on the ball. Also it helps you aim the ball more precisely and hit the corners of the goal. Second is to take a big drop step and twist your hips is to create more power on your shoot. Lastly you need to follow through your swing. It’s just like in basketball and how you need yo follow through on your shoot or in soccer and how you need to follow through on your kick. Another part important part of lax is how to catch the ball because if you can’t catch the ball you can’t really score. The most important part of catching the ball is keeping your hands in front of your body. If you do this you can catch the ball from almost anywhere. How you actually receive the ball is another crucial technique. When the ball is going into your stick, you need to bring the stick towards you so the ball won’t pop out. If you just keep your stick out there the ball will hit your mesh and fly out of your head. The last thing I am going to tell you about is how to cradle the ball. If you cannot cradle the ball, when you are trying to move down the field, you will get the ball knocked out and taking away. A way to not let that happen is to bring your stick up strongly and bring it down strongly.

Analysis of Analytical Discrimination Essay -- Essays Papers

Analysis of Analytical Discrimination If one was required to put a definition on analytical discrimination, what would it mean? In the article â€Å"Discrimination is a virtue,† author Robert Keith Miller discusses the word â€Å"discrimination† and its true meanings, stating it as just knowing a difference. So if the question were asked once again, would it be possible to discriminate the appeals used in analytical analysis? Miller presents us stories and examples to point out a â€Å"lost† definition of a word often overheard, but never studied. His use of appeals sides with logos, discriminates against ethos, and makes anti-pathos a reality. His writing appeals to the mind, leaving much to ponder, though these thoughts may be lost in the whirlwind of ink ideas thrown into a paperback debate. This article focuses on different situations to discuss the problems within. This topical discussion is effective being as there are no two clear sides for argument, and no steps to concluding a definite answer. This articles presentation leaves it open for logos, the writer seemingly shuns or does not have the use of ethos and pathos. Miller has written for Newsweek, where this article comes from. He has also written writing handbooks, such as Motives for Writing (McGraw-Hill) and Hodges’ HarBrace Handbook (Harcourt College Publishers). He is an educator in argument techniques, writing Informed Argument: A Multidisciplinary Reader and Guide. The audience for his article is people of open mind and education. His appeals to logic show a need to take apart his examples and examine them to find their meanings. When he presents his ideas, there is a need to understand each situation, and... ...f logos is a main theme in the argument. Miller needs people to think about what he is presenting to have an effect on them. To a concentrated audience, his appeals make a good impression and even some realizations. An argument that offers a change in a language may come as hard for the reader to understand, but Miller presents examples in which he change makes sense to arouse the readers mind. This use of examples may be rampant and unconnected in some aspects, but all do serve the main purpose and relate to the main argument. Miller’s techniques form an informative and interesting essay. I believe that he has found his purpose and offered his point in the best possible way considering the subject matter. In interpreting his essay, Miller’s own words seem to sum it up best: â€Å"Let us be open-minded by all means, but not so open-minded that our brains fall out.†

Coffee preparation Essay

1. Introduction 1. 1 fig Coffee  is a  brewed  beverage  with a distinct aroma and flavor, prepared from the roasted seeds of the  Coffea  plant. The seeds are found in coffee â€Å"cherries†, which grow on trees cultivated in  over 70 countries, primarily in equatorial  America, Southeast,  South Asia  and  Africa. Green (unroasted) coffee is one of the most traded agricultural commodities in the world. Coffee is slightly acidic (pH 5. 0–5. 1) and can have a stimulating effect on humans because of its  caffeine  content. It is one of the most consumed drinks in the world. Wild coffee’s energizing effect was likely first discovered in the northeast region of Ethiopia. Coffee cultivation first took place in southern Arabia;[4]  the earliest credible evidence of coffee-drinking appears in the middle of the 15th century in the Sufi  shrines of  Yemen. In East Africa and Yemen, coffee was used in native religious ceremonies that were in competition with the Christian Church. As a result, the  Ethiopian Church  banned its secular consumption until the reign of Emperor  Menelik II of Ethiopia. The beverage was also banned in  Ottoman  Turkey during the 17th century for political reasons  and was associated with rebellious political activities in Europe. Coffee berries, which contain the coffee seeds, are produced by several species of small  evergreen  bush of the  genus  Coffea. The two most commonly grown are also the most highly regarded  Coffea arabica, and the â€Å"robusta† form of the hardier Coffea canephora. The latter is resistant to the devastating coffee leaf rust (Hemileia vastatrix). Once ripe, coffee berries are picked, processed, and dried. The seeds are then roasted to varying degrees, depending on the desired flavor, before being ground and brewed to create coffee. Coffee can be prepared and presented in a variety of ways. An important export commodity, coffee was the top agricultural export for  twelve countries  in 2004,  and it was the world’s seventh-largest legal agricultural export by value in 2005. Some controversy is associated with coffee cultivation and its impact on the environment. Consequently,  organic coffee  is an expanding market. Many studies have examined the  health effects of coffee, and whether the overall effects of coffee consumption are positive or negative has been widely disputed. The method of brewing coffee has been found to be important in relation to its effects on health. For instance, preparing coffee in a  French press  leaves more oils in the drink compared with coffee prepared with a paper  coffee filter. This might raise the drinker’s level of â€Å"bad cholesterol. † Etymology The first reference to â€Å"coffee† in the English language is in the form  chaoua  and dates to 1598. In English and other European languages,  coffee  derives from the  Ottoman Turkish  kahve, via the Italian  caffe. The Turkish word in turn was borrowed from the  Arabic: ,  qahwah. Arab  lexicographers  maintain that  qahwah  originally referred to a type of  wine, and gave its  etymology, in turn, to the verb qaha, signifying â€Å"to have no appetite†,  since this beverage was thought to dull one’s hunger. Several alternative etymologies exist that hold that the Arab form may disguise a  loanword  from an Ethiopian or African source, suggesting  Kaffa, the highland in south western  Ethiopia  as one, since the plant is indigenous to that area. However, the term used in that region for the berry and plant is  bunn, the native name in  Shoa  being  bun. History Ethiopian ancestors of today’s  Oromo people  were believed to have been the first to recognize the energizing effect of the coffee plant,  though no direct evidence has been found indicating where in Africa coffee grew or who among the natives might have used it as a stimulant or even known about it, earlier than the 17th century. The story of  Kaldi, the 9th-century Ethiopian goatherder who discovered coffee, did not appear in writing until 1671 and is probably  apocryphal. Other accounts attribute the discovery of coffee to Sheik Omar. According to the ancient chronicle (preserved in the Abd-Al-Kadir manuscript), Omar, who was known for his ability to cure the sick through prayer, was once exiled from Mocha, Yemen to a desert cave near Ousab. Starving, Omar chewed berries from nearby shrubbery, but found them to be bitter. He tried roasting the seeds to improve the flavor, but they became hard. He then tried boiling them to soften the seed, which resulted in a fragrant brown liquid. Upon drinking the liquid Omar was revitalized and sustained for days. As stories of this â€Å"miracle drug† reached Mocha, Omar was asked to return and was made a saint. From Ethiopia, the beverage was introduced into the Arab world through Egypt and Yemen. The earliest credible evidence of either coffee drinking or knowledge of the coffee tree appears in the middle of the 15th century, in the Sufi  monasteries around  Mokha  in Yemen. It was here in  Arabia  that coffee seeds were first roasted and brewed, in a similar way to how it is now prepared. By the 16th century, it had reached the rest of the Middle East,  Persia,  Turkey, and  northern Africa. Coffee seeds were first exported from Ethiopia to Yemen. Yemeni traders brought coffee back to their homeland and began to cultivate the seed. The first coffee smuggled out of the Middle East was by  Sufi  Baba Budan  from  Yemen  to India in 1670. Before then, all exported coffee was boiled or otherwise sterilised. Portraits of Baba Budan depict him as having smuggled seven coffee seeds by strapping them to his chest. The first plants grown from these smuggled seeds were planted in  Mysore. Coffee then spread to Italy, and to the rest of Europe, to  Indonesia, and to the Americas. In 1583,  Leonhard Rauwolf, a German physician, gave this description of coffee after returning from a ten-year trip to the  Near East: A beverage as black as ink, useful against numerous  illnesses, particularly those of the stomach. Its consumers take it in the morning, quite frankly, in a porcelain cup that is passed around and from which each one drinks a cupful. It is composed of water and the fruit from a bush called bunnu. —Leonard Rauwolf,  Reise in die Morgenlander  (in German). From the  Middle East, coffee spread to Italy. The thriving trade between  Venice  and North Africa, Egypt, and the Middle East brought many goods, including coffee, to the Venetian port. From Venice, it was introduced to the rest of Europe. Coffee became more widely accepted after it was deemed a Christian beverage by  Pope Clement VIII  in 1600, despite appeals to ban the â€Å"Muslim drink. † The first European coffee house opened in Italy in 1645. The  Dutch East India Company  was the first to import coffee on a large scale. The Dutch later grew the crop in  Java  and  Ceylon. The first exports of  Indonesian coffee  from  Java  to the Netherlands occurred in 1711. Through the efforts of the  British East India Company, coffee became popular in England as well. Oxford’s  Queen’s Lane Coffee House, established in 1654, is still in existence today. Coffee was introduced in France in 1657 and in Austria and Poland after the 1683  Battle of Vienna, when coffee was captured from supplies of the defeated  Turks. When coffee reached North America during the Colonial period, it was initially not as successful as it had been in Europe as alcoholic beverages remained more popular. During the  Revolutionary War, the demand for coffee increased so much that dealers had to hoard their scarce supplies and raise prices dramatically; this was also due to the reduced availability of tea from British merchants. After the  War of 1812, during which Britain temporarily cut off access to  tea  imports, the Americans’ taste for coffee grew, and high demand during the  American Civil War  together with advances in brewing technology secured the position of coffee as an everyday commodity in the United States. Coffee consumption declined in England, giving way to tea during the 18th century. The latter beverage was simpler to make, and had become cheaper with the British conquest of India and the tea industry there. During the  Age of Sail,  seamen  aboard ships of the British  Royal Navy  made substitute coffee by dissolving burnt bread in hot water. The Frenchman  Gabriel de Clieu  brought a coffee plant to the French territory of  Martinique  in the Caribbean, from which much of the world’s cultivated Arabica coffee is descended. Coffee thrived in the climate and was conveyed across the Americas. The territory of San Domingo (now  Haiti) saw coffee cultivated from 1734, and by 1788 it supplied half the world’s coffee. The conditions that the slaves worked in on coffee plantations were a factor in the soon to follow  Haitian Revolution. The coffee industry never fully recovered there. Meanwhile, coffee had been  introduced to Brazil  in 1727, although its cultivation did not gather momentum until independence in 1822. After this time, massive tracts of rainforest were cleared first from the vicinity of Rio and later Sao Paulo for coffee plantations. Cultivation was taken up by many countries in Central America in the latter half of the 19th century, and almost all involved the large-scale displacement and exploitation of the indigenous people. Harsh conditions led to many uprisings, coups and bloody suppression of peasants. The notable exception was  Costa Rica, where lack of ready labor prevented the formation of large farms. Smaller farms and more egalitarian conditions ameliorated unrest over the 19th and 20th centuries. Coffee has become a vital  cash crop  for many  developing  countries. Over one hundred million people in  developing countries  have become dependent on coffee as their primary source of income. It has become the primary export and backbone for African countries like Uganda, Burundi, Rwanda, and Ethiopia,  as well as many Central American countries. World production In 2011  Brazil  was the world leader in production of green coffee, followed by  Vietnam,  Indonesia  and  Colombia. Arabica coffee seeds are cultivated in  Latin America,  eastern Africa, Arabia, or Asia. Robusta coffee seeds are grown in western and  central Africa, throughout  Southeast Asia, and to some extent in Brazil. Seeds from different countries or regions can usually be distinguished by differences in flavor, aroma,  body, and acidity. These taste characteristics are dependent not only on the coffee’s growing region, but also on genetic subspecies (varietals) and processing. Varietals are generally known by the region in which they are grown, such as  Colombian,  Java and  Kona. 2011 Top twenty green coffee producers| Rank| Country| Tonnes| Bags x1000| 1|   Brazil| 2,609,040| 43,484| 2|   Vietnam| 1,200,000| 20,000| 3|   Indonesia| 495,000| 8,250| 4|   Colombia| 468,000| 7,800| 5|   Ethiopia| 390,000| 6,500|. 6|   Peru| 326,580| 5,443| 7|   India| 319,980| 5,333| 8|   Honduras| 270,000| 4,500| 9|   Mexico| 258,000| 4,300| 10|   Guatemala| 225,000| 3,750| 11|   Uganda| 192,720| 3,212| 12|   Nicaragua| 126,000| 2,100| 13|   Costa Rica| 107,940| 1,799| 14|   Ivory Coast| 96,000| 1,600| 15|   Papua New Guinea| 84,900| 1,415| 16|   El Salvador| 70,500| 1,175| 17|   Cambodia| 64,980| 1,083| 18|   Ecuador| 64,500| 1,075| 19|   Democratic Republic of the Congo| 63,360| 1,056| 20|   Venezuela| 60,000| 1,000| Total|   Ã‚  World| 7,875,180| 131,253| 1. 1 (table) Biology 1. 2 fig (Illustration of  Coffea arabica  plant and seeds). Several species of shrub of the genus  Coffea  produce the berries from which coffee is extracted. The two main species commercially cultivated are  Coffea canephora  (predominantly a form known as ‘robusta’) andC. arabica. C. arabica, the most highly regarded species, is native to the southwestern highlands of Ethiopia and the  Boma Plateau  in southeastern Sudan and possibly  Mount Marsabit  in northern  Kenya. C. canephora  is native to western and central Subsaharan Africa, from  Guinea  to the  Uganda  and southern Sudan. Less popular species are  C. liberica,  excelsa,  stenophylla,  mauritiana, and  racemosa. All coffee plants are classified in the large family  Rubiaceae. They are  evergreen  shrubs or small trees that may grow 5  m (15  ft) tall when unpruned. The leaves are dark green and glossy, usually 10–15  cm (4–6  in) long and 6  cm (2. 4  in) wide. The flowers are axillary, and clusters of fragrant white flowers bloom simultaneously and are followed by oval berries of about 1. 5  cm (0. 6  in). Green when immature, they ripen to yellow, then crimson, before turning black on drying. Each berry usually contains two seeds, but 5–10% of the berries  have only one; these are called  peaberries. Berries ripen in seven to nine months. Coffea arabica  is predominantly self-pollinating, and as a result the seedlings are generally uniform and vary little from their parents. In contrast,  Coffea canephora,  C. excelsa, and  C. liberica  are self-incompatible and require  outcrossing. This means that useful forms and hybrids must be propagated vegetatively. Cuttings, grafting, and budding are the usual methods of vegetative propagation. On the other hand, there is great scope for experimentation in search of potential new strains. 2. Coffee Production Processing Coffee berries and their seeds undergo several processes before they become the familiar roasted coffee. Berries have been traditionally selectively picked by hand; a labor intensive method, it involves the selection of only the berries at the peak of ripeness. More commonly, crops are strip picked, where all berries are harvested simultaneously regardless of ripeness by person or machine. After picking, green coffee is processed by one of two methods—the dry process method, simpler and less labor intensive as the berries can be strip picked, and the wet process method, which incorporates fermentation into the process and yields a mild coffee. 2. 1 fig -Coffee sorting in Dutch East Indies (now Indonesia). 2. 2 fig – Coffee berries from Kerala, India Then they are sorted by ripeness and color and most often the flesh of the berry is removed, usually by machine, and the seeds are fermented to remove the slimy layer of mucilage still present on the seed. When the fermentation is finished, the seeds are washed with large quantities of fresh water to remove the fermentation residue, which generates massive amounts of coffee wastewater. Finally, the seeds are dried. The best (but least used) method of drying coffee is using drying tables. In this method, the pulped and fermented coffee is spread thinly on raised beds, which allows the air to pass on all sides of the coffee, and then the coffee is mixed by hand. In this method the drying that takes place is more uniform, and fermentation is less likely. Most African coffee is dried in this manner and certain coffee farms around the world are starting to use this traditional method. Next, the coffee is sorted, and labeled as green coffee. Another way to let the coffee seeds dry is to let them sit on a concrete patio and rake over them in the sunlight. Some companies use cylinders to pump in heated air to dry the coffee seeds, though this is generally in places where the humidity is very high. Some coffee undergoes a peculiar process, such as kopi luwak. It is made from the seeds of coffee berries which have been eaten by the Asian Palm Civet and other related civets, passing through its digestive tract. This process resulted in coffee seeds with much less bitterness, widely noted as the most expensive coffee in the world with prices reaching $160 per pound. Roasting 2. 3 fig – Roasted coffee seeds The next step in the process is the roasting of the green coffee. Coffee is usually sold in a roasted state, and with rare exceptions all coffee is roasted before it is consumed. It can be sold roasted by the supplier, or it can be home roasted. The roasting process influences the taste of the beverage by changing the coffee seed both physically and chemically. The seed decreases in weight as moisture is lost and increases in volume, causing it to become less dense. The density of the seed also influences the strength of the coffee and requirements for packaging. The actual roasting begins when the temperature inside the seed reaches approximately 200  °C (392  °F), though different varieties of seeds differ in moisture and density and therefore roast at different rates. During roasting, caramelization occurs as intense heat breaks down starches, changing them to simple sugars that begin to brown, which alters the color of the seed. 2. 4 fig – The appearance of unroasted, green coffee seeds. Sucrose is rapidly lost during the roasting process and may disappear entirely in darker roasts. During roasting, aromatic oils and acids weaken, changing the flavor; at 205  °C (401  °F), other oils start to develop. One of these oils, caffeol, is created at about 200  °C (392  °F), which is largely responsible for coffee’s aroma and flavor. Grading the roasted seeds. Depending on the color of the roasted seeds as perceived by the human eye, they will be labeled as light, medium light, medium, medium dark, dark, or very dark. A more accurate method of discerning the degree of roast involves measuring the reflected light from roasted seeds illuminated with a light source in the near infrared spectrum. This elaborate light meter uses a process known as spectroscopy to return a number that consistently indicates the roasted coffee’s relative degree of roast or flavor development. Roast characteristics The degree of roast has an effect upon coffee flavor and body. Darker roasts are generally bolder because they have less fiber content and a more sugary flavor. Lighter roasts have a more complex and therefore perceived stronger flavor from aromatic oils and acids otherwise destroyed by longer roasting times. A small amount of chaff is produced during roasting from the skin left on the seed after processing. Chaff is usually removed from the seeds by air movement, though a small amount is added to dark roast coffees to soak up oils on the seeds. Decaffeination Decaffeination may also be part of the processing that coffee seeds undergo. Seeds are decaffeinated when they are still green. Many methods can remove caffeine from coffee, but all involve soaking the green seeds in hot water (often called the â€Å"Swiss water process†) or steaming them, then using a solvent to dissolve caffeine-containing oils. Decaffeination is often done by processing companies, and the extracted caffeine is usually sold to the pharmaceutical industry. Storage Once roasted, coffee seeds must be stored properly to preserve the fresh taste of the seed. Ideally, the container must be airtight and kept in a cool, dry and dark place. In order of importance: air, moisture, heat, and light are the environmental factors responsible for deteriorating flavor in coffee seeds. Folded-over bags, a common way consumers often purchase coffee, are generally not ideal for long-term storage because they allow air to enter. A better package contains a one-way valve, which prevents air from entering. In 1931, a method of vacuum packed cans of coffee was introduced, in which the roasted coffee was packed, 99% of the air was removed and the coffee in the can could be stored indefinitely until the can was opened. Today this method is in mass use for coffee in a large part of the world. Brewing 2. 5 fig – Espresso brewing, showing desirable dark reddish-brown crema Coffee seeds must be ground and brewed to create a beverage. The criteria for choosing a method include flavor and economy. Almost all methods of preparing coffee require the seeds to be ground and mixed with hot water long enough to extract the flavor, but without over extraction that draws out bitter compounds. The spent grounds are removed and the liquid is consumed. There are many brewing variations such as the fineness of grind, the ways in which the water extracts the flavor, additional flavorings (sugar, milk, spices), and spent ground separation techniques. The ideal holding temperature is 79 to 85  °C (174 to 185  °F) and the ideal serving temperature is 68 to 79  °C (154 to 174  °F). The roasted coffee seeds may be ground at a roastery, in a grocery store, or in the home. Most coffee is roasted and ground at a roastery and sold in packaged form, though roasted coffee seeds can be ground at home immediately before consumption. It is also possible, though uncommon; to roast raw seeds at home. Coffee seeds may be ground in several ways. A burr grinder uses revolving elements to shear the seed; a blade grinder cuts the seeds with blades moving at high speed; and a mortar and pestle crushes the seeds. For most brewing methods, a burr grinder is deemed superior because the grind is more even and the grind size can be adjusted. 2. 6 fig – (An Ethiopian woman preparing coffee at a traditional ceremony. She roasts, crushes and brews the coffee on the spot. ) The type of grind is often named after the brewing method for which it is generally used. Turkish grind is the finest grind, while coffee percolator or French press are the coarsest grinds. The most common grinds are between the extremes; a medium grind is used in most common home coffee-brewing machines. Coffee may be brewed by several methods: boiled, steeped, or pressurized. Brewing coffee by boiling was the earliest method, and Turkish coffee is an example of this method. It is prepared by grinding or pounding the seeds to a fine powder, then adding it to water and bringing it to the boil for no more than an instant in a pot called a cezve or, in Greek, a briki. This produces a strong coffee with a layer of foam on the surface and sediment (which is not meant for drinking) settling on the bottom of the cup. Coffee percolators and automatic coffeemakers brew coffee using gravity. In an automatic coffeemaker hot water drips onto coffee grounds held in a coffee filter made of paper, plastic, or perforated metal, allowing the water to seep through the ground coffee while extracting its oils and essences. The liquid drips through the coffee and the filter into a carafe or pot, and the spent grounds are retained in the filter. In a percolator, boiling water is forced into a chamber above a filter by steam pressure created by boiling. The water then seeps through the grounds, and the process is repeated until terminated by removing from the heat, by an internal timer, or by a thermostat that turns off the heater when the entire pot reaches a certain temperature. Coffee may be brewed by steeping in a device such as a French press (also known as a cafetiere, coffee press or coffee plunger). Ground coffee and hot water are combined in a cylindrical vessel and left to brew for a few minutes. A circular filter which fits tightly in the cylinder fixed to a plunger is then pushed down from the top to force the grounds to the bottom. Because the coffee grounds are in direct contact with the water, all the coffee oils remain in the beverage, making it stronger and leaving more sediment than in coffee made by an automatic coffee machine. The coffee is poured from the container; the filter retains the grounds at the bottom. 95% of the caffeine is released from the coffee seeds within the first minute of brewing. The espresso method forces hot pressurized and vaporized water through ground coffee. As a result of brewing under high pressure (ideally between 9–10 atm), the espresso beverage is more concentrated (as much as 10 to 15 times the quantity of coffee to water as gravity-brewing methods can produce) and has a more complex physical and chemical constitution. A well-prepared espresso has reddish-brown foam called crema that floats on the surface. Other pressurized water methods include the moka pot and vacuum coffee maker. Cold brew coffee is made by steeping coarsely ground seeds in cold water for several hours, then filtering them. [85] This results in a brew lower in acidity than most hot-brewing methods. Serving 2. 7 fig Presentation can be an integral part of coffeehouse service, as illustrated by the common rosetta design layered into this latte. Once brewed, coffee may be served in a variety of ways. Drip-brewed, percolated, or French-pressed/cafetiere coffee may be served as white coffee with a dairy product such as milk or cream, or dairy substitute, or as black coffee with no such addition. It may be sweetened with sugar or artificial sweetener. When served cold, it is called iced coffee. Espresso-based coffee has a wide variety of possible presentations. In its most basic form, espresso is served alone as a shot or with hot water added, known as Caffe Americano. Reversely, long black is made by pouring espresso in water, which retains the crema compared to Caffe Americano. Milk is added in various forms to espresso: steamed milk makes a caffe latte, equal parts steamed milk and milk froth make a cappuccino,[86] and a dollop of hot foamed milk on top creates a caffe macchiato. The use of steamed milk to form patterns such as hearts or maple leaves is referred to as latte art. Coffee can also be incorporated with alcohol in beverages—it is combined with whiskey in Irish coffee, and forms the base of alcoholic coffee liqueurs such as Kahlua, and Tia Maria. Coffee is also sometimes used in the brewing process of darker beers, such as a stout or porter. Instant coffee A number of products are sold for the convenience of consumers who do not want to prepare their own coffee. Instant coffee is dried into soluble powder or freeze-dried into granules that can be quickly dissolved in hot water. Originally invented in 1907, it rapidly gained in popularity in many countries in the post-war period, with Nescafe being the most popular product. Many consumers determined that the convenience in preparing a cup of instant coffee more than made up for a perceived inferior taste. Paralleling (and complementing) the rapid rise of instant coffee was the coffee vending machine, invented in 1947 and multiplying rapidly through the 1950s. Canned coffee has been popular in Asian countries for many years, particularly in China, Japan, South Korea, and Taiwan. Vending machines typically sell varieties of flavored canned coffee, much like brewed or percolated coffee, available both hot and cold. Japanese convenience stores and groceries also have a wide availability of bottled coffee drinks, which are typically lightly sweetened and pre-blended with milk. Bottled coffee drinks are also consumed in the United States. Liquid coffee concentrates are sometimes used in large institutional situations where coffee needs to be produced for thousands of people at the same time. It is described as having a flavor about as good as low-grade robusta coffee, and costs about 10? a cup to produce. The machines can process up to 500 cups an hour or 1,000 if the water is preheated. 3. Coffee beans A coffee bean is a seed of the coffee plant. It is the pit inside the red or purple fruit often referred to as a cherry. Even though they are seeds, they are incorrectly referred to as ‘beans’ because of their resemblance to true beans. The fruits – coffee cherries or coffee berries – most commonly contain two stones with their flat sides together. A small percentage of cherries contain a single seed, instead of the usual two. This is called a peaberry. Like Brazil nuts (a seed) and white rice, coffee seeds consist mostly of endosperm. The two most economically important varieties of coffee plant are the Arabica and the Robusta; 75-80% of the coffee produced worldwide is Arabica and 20% is Robusta. Arabica seeds consist of 0. 8-1. 4% caffeine and Robusta seeds consist of 1. 7-4% caffeine. As coffee is one of the world’s most widely consumed beverages, coffee seeds are a major cash crop, and an important export product, counting for over 50% of some developing nations’ foreign exchange earnings. The United States imports more coffee than any other nation. In 2009 the average person in the United States consumed 4. 09 kg (9 lbs) of coffee. Cultivation of the coffee seed originated in Ethiopia, in approximately 850 C. E. Farming of the coffee plant then spread to the rest of Arabia, where it was first mentioned in writing around 900 C. E. The Yemenites guarded it carefully, but some plants were eventually smuggled out to the Dutch, who kept a few plants for gardens in the Netherlands. The Americas were first introduced to the plants around 1723. South America is now responsible for approximately 45% of the world’s total coffee exports. Most of this coffee is made in Brazil. Significant dates * First cultivation in Europe (also first cultivation outside of east Africa/Arabia) – 1616 * First cultivation in India (Malabar) – late 1600s * First cultivation in Java – 1699 * First cultivation in Caribbean (Cuba, Haiti, Jamaica, Santo Domingo, Puerto Rico) – 1715–1730 * First cultivation in South America – 1730. * First cultivation in Dutch East Indies – 1720 * Roasted seeds first sold on retail market (Pittsburgh) – 1865 * Important spray-drying techniques developed in 1950s Coffee plant The coffee tree averages from 5–10 m (16–33 ft) in height. As the tree gets older, it branches less and less and bears more leaves and fruit. The tree typically begins to bear fruit 3–4 years after being planted, and continues to produce for 10–20 more years, depending on the type of plant and the area. Coffee plants are grown in rows several feet apart. Some farmers plant fruit trees around them or plant the coffee on the sides of hills, because they need specific conditions to flourish. Ideally, Arabica coffee seeds are grown at temperatures between 15–24  °C (59–75  °F) and Robusta at 24–30  °C (75–86  °F) and receive between 15–30 cm (5. 9–12 in) of rainfall per year. Heavy rain is needed in the beginning of the season when the fruit is developing, and less late in the season as it ripens. The harvesting period can be anywhere from three weeks to three months, and in some places the harvesting period continues all year round. Content of green coffee seeds The term â€Å"green coffee seed† refers to unroasted mature or immature coffee seeds. These have been processed by wet or dry methods for removing the outer pulp and mucilage, and have an intact wax layer on the outer surface. When immature, they are green. When mature, they have a brown to yellow or reddish color, and typically weigh 300 to 330 mg per dried coffee seed. Nonvolatile and volatile compounds in green coffee seeds, such as caffeine, deter many insects and animals from eating them. Further, both nonvolatile and volatile compounds contribute to the flavor of the coffee seed when it is roasted. Nonvolatile nitrogenous compounds (including alkaloids, trigonelline, proteins and free amino acids) and carbohydrates are of major importance in producing the full aroma of roasted coffee, and for its biological action. * Nonvolatile alkaloids 3. 1 fig – Coffea canephora green seeds on a tree in Goa, India. Caffeine (1,3,7-trimethyl-xanthine) is the alkaloid most present in green and roasted coffee seeds. The content of caffeine is between 1. 0% and 2. 5% by weight of dry green coffee seeds. The content of caffeine does not change during maturation of green coffee seeds. Lower concentrations of theophylline, theobromine, paraxanthine, liberine, and methylliberine can be found. The concentration of theophylline, an alkaloid noted for its presence in green tea, is reduced during the roasting process, usually about 15 minutes at 230  °C (446  °F), whereas the concentration of most other alkaloids are not changed. The solubility of caffeine in water increases with temperature and with the addition of chlorogenic acids, citric acid, or tartaric acid, all of which are present in green coffee seeds. For example, 1 g (0. 035 oz) caffeine dissolves in 46 ml (1. 6 US fl oz) of water at room temperature, and 5. 5 ml (0. 19 US fl oz) at 80  °C (176  °F). The xanthine alkaloids are odorless, but have a bitter taste in water, which is masked by organic acids present in green coffee, however. Trigonelline (N-methyl-nicotinate) is a derivative of vitamin B6 that is not as bitter as caffeine. In green coffee seeds, the content is between 0. 6% and 1. 0%. At a roasting temperature of 230  °C (446  °F), 85% of the trigonelline is degraded to nicotinic acid, leaving small amounts of the unchanged molecule in the roasted seeds. In green coffee seeds, trigonelline is synthesized from nicotinic acid (pyridinium-3-carboxylic acid) by methylation from methionine, a sulfur-containing amino acid. Mutagenic activity of trigonelline has been reported.
