Malaria - Research Paper Example The cells then invade the liver and become hypnozoites. These undergo the division and are released in the blood. The parasite infected cells burst and release further more mature protozoa in the blood which causes the chills and fever. The repeated episodes of this blood phase keep on occurring till the treatment. The parasite, therefore, acts as a carrier of the plasmodium and spread malaria (Schwartz, Parise, Kozarsky, & Cetron, 2003). It has just come to my knowledge that there was another genus of Plasmodium known as P. knowlesi. It was earlier recognized as the main cause of malaria. But the research later showed that it mostly infects the Macaques in Southeast Asia and humans to some extent. Malaria, in this case, spreads from animal to human. The animal was thought to be monkey which has been documented as a cause of human infections and deaths in the past. I also came from this fact that the malaria infected individual should not donate blood till three years. The blood bank follows the strict rules for accepting the donors who have been in the endemic area. The donor must remain symptomless for these years in order to be able to donate blood later in life. Among all the malaria species, P. vax and P. oval can for dormant liver stages that can reside inside the body for up to 3 to 4 years. The pregnant women are more susceptible to the disease by P. falciparum. P. falciparum infection may lead to the decrease baby’ weight which then reduces the chance of baby survival.... knowlesi.

EPIDEMIOLOGY It is an international health problem affecting 215 million people worldwide. Annually it causes about 665,000 deaths due to poor treatment regimen and atmospheric conditions. Despite the development and research on the disease, there are still many endemic areas for the occurrence of malaria. CDC has provided the data about these endemic countries, which is derived from the different sources like World Health Organization. Usually the attack is most common in the Southeast Asia, Africa and some parts of the Caribbean and Eastern Europe. Of all these cases, 65 % occur in Africa, 19% in Asia, 15% in Caribbean and to the lesser number in Europe. (Cdc.gov, 2011) It occurs in the tropical and subtropical

Strategic Information System Essay Example | Topics and Well Written Essays - 2000 words - 1

Strategic Information System - Essay Example y, the information system is used as an academic sort of study of the systems usually with some particular reference to information and complementary networks of software and hardware that organizations and the people use in collecting, creating, filtering, processing and distributing data. Any the information system normally aims at supporting the operations, decision-making and the management (Haav, 2009). The strategic systems usually are computer systems that normally implement the business strategies. They include the systems where the information service resources that are applied to the strategic business opportunities in a manner that the computer systems have a great impact on the organizations products as well as the business operations (Ulrich, 2010). The strategic information systems mostly are those that are developed in response to the corporate opportunities and the initiatives. The central idea usually comes from the business operational people and the information services that supply the technological abilities and the capabilities in realizing profitable results. Zara, one among the world’s largest companies of fashion had a simple and a unique type of focus in linking the customers demand to the manufacturing and consequently linked the manufacturing to the distribution. Their major issue has been related to the current information technology kind of platform that they use in operating their chain in the retail stores (Quintela VarajaÃŒÆ'o, 2010). The business model could be split into three main components which are; capabilities, concept and the value drivers. The most fundamental concept has been maintaining the production, the distribution and the design that eventually would enable the organization to be able to respond quickly to the shifts in the customer demands. The value drivers for the organization conclusively are tangible and intangible as well in the benefits that are usually brought back to the stakeholders (Barzdin, 2011).

Qualities Of A Good Football Player Physical Education Essay

Qualities Of A Good Football Player Physical Education Essay Football has become a sport that interest by all population in this world. To play or become a good football player, the person must master many skills and have a healthy physical and mental. Football players also must combine speed, strength, agility, power, and endurance as basic qualities before the individual skills inherent to the playing of soccer can be utilized and depend on the position such as defense, strikers, midfielder and goal keeper. The understanding of the physical and the mental demands of the sport will enable a more scientific approach to the training of soccer players by (Bell and Rhodes 1975; Caru et. al. 1970; Fardy 1969). According to (Nicks et. al. 2006; Romer et. al. 2002) Soccer is one of the intermittent sports that require high intensity bouts of exercise, with periods of passive or active recovery and coherent performance in repeated sprints need sufficient recovery between sprints. So the player must have strong muscles, high muscular endurance, have strong core and have high level of aerobic capacity because the football game are played for 90 minutes. So the training must contain high aerobic training to improve cardiovascular and pulmonary functions so the athlete can cope with the sport. Physiological assessment of athletes can provide an opportunity to examine or test the adaptation to specific types of exercises and training. These adaptations can be valuable to the clinician, coaches and athletes themselves. For example, lab test that can be proceed to examine the adaptation to specific types of exercises and training. To test the adaptation to the lung we can use pulmonary functions test to examine the effectiveness of lung muscles functioning, to check the vital capacity and to estimate the lung volumes. The function of the lung is to deliver O2 to gas exchanged surface and exhaust CO2 to atmosphere. To achieve this with brain functioning normally, breath begins with contraction of inspiratory muscle enlarging the thorax, lowering intrathoracic and pleural pressures, enlarging the alveoli and airways, expanding the alveolar gas so reducing its pressure below atmospheric. Air at atmospheric pressure must flow into the thorax where it is conducted to, and diffuses, out into the alveoli. The carriage of air through the airways depends on the patency of the tube as well as on the consistency of the lung and the power of the respiratory muscles. At any one moment approximately 100ml of desaturated blood, with a strong affinity for O2, is spread over an area of 70 square meters( area of pulmonary capillary bed ) separated from air by a membrane 0.2 micron thick. Oxygen from alveolar air diffuses rapidly across the alveolar capillary membrane and is finally chemically combined with hemoglob in molecules within the circulating red blood cells (RBC), CO2 diffuses into opposite direction and is eliminated in expired gas. The Vital capacity test is one of the oldest and most common respiratory tests. The measurement of vital capacity (VC) simply requires that an individual blow as large a breath of air as possible into a spirometer. Thus, the person expels three of the four components of the total lung volume when performing the vital test. There are inspiratory reserve volume (IRV), tidal volume (TV) and expiratory reserve volume (ERV). It provides an indirect indication of the size of the lung, although it is not a complete measure of the entire lung size because it does not account for residual volume. In general facts, vital capacity relate to three uncontrolled characteristics which are age, stature and gender. Lung function measurements also may be made for several reasons. They are useful in describing the lung for diagnostic purpose and subsequently in monitoring change. Accuracy and consistency are therefore very important, and a convention exists for the procedure of measurement and expression of result. In general, a measurement will only be accepted after multiple attempts have been scrutinized and expressed under standard conditions. These are usually body temperature and atmospheric pressure. To guarantee accuracy, laboratory practice should include regular physical and biological calibration of the equipment. Standard for good laboratory conduct have been described greatly by British Thoracic Society or association of respiratory technologist and physiologist 1997. In health there are several factors which influence the magnitude of the lung function. These include height, sex, age, and to a lesser degree weight and ethnic origin (Cotes1979, Anthonisen1986). As a result, assessment of normalcy can only be compared with reference values. The better can be obtained from the study of larger numbers of normal people from the relevant population (European community for Coal and Steel 1983). Once obtained, results can be expressed as percentage predicted or, more correctly, by comparison with the 95% confidence interval for the valves. Problem statement. It is interesting to know whether there are any different of lung volumes and lung capacities base on the different position in the football team such as striker position and defenses position. In football team, the defenders position tasks are different with the striker position task, for example the defensive position, the job of the centre backs or  central defenders  is to stop opposing players, particularly the strikers, from getting the opportunity to score, and to clear the ball from their own penalty area. So usually the defense has big physical to stop the striker, but different with the striker position, usually the strikers position players have not too big physical, because these positions are for the fast person to score the goal. This study of pulmonary function of the Uitm football players base on position, have taken students group of both striker position and defense position of aged between 19-25 years and focused on essential parameters including, FVC and has used Spirometer. The spirometer device used to assess these parameters. This study mainly concentrates on lung parameters including Forced Vital Capacity (FVC) and how far it varies base on the position such as striker and defense. The FVC also use to assess the lung function of Uitm soccer players. Operational Terms 1.2.1 Exhalation is act or an instance of exhaling air. From journal sources Masaoka Y, Satoh H, Akai L, Homma I. (2010) 1.2.2 Inhalation is the drawing of air or other substances into the lung. From internet sources http://en.wikipedia.org/wiki 1.2.3 Total lung capacity are refers to the total amount of air in the lungs after taking the deepest breath possible. From internet sources http://en.wikipedia.org/wiki 1.2.4 Ventilation is a cyclic process of inspiration and expiration whereby optimal levels of Oxygen and cabondioxide are maintained in the alveoli and arterial blood. 1.2.5 Tidal Volume (VT) is defined as the amount of air that is inspired and expired during normal resting ventilation. 1.2.6 Forced Vital Capacity (FVC) is the maneuvers in which the maximum amount of air that can be exhaled following a inspiratory effort. 1.2.7 Maximum voluntary ventilation (MVV) is defined as the maximum volume of air that can be breathed voluntarily by an individual in one minute. From internet sources http://www.answer.com/topic/maximum-breathing-technique Objectives In this study, there are some purposes or objective that can be seen. They are; To measure the level of fitness of Uitm football players by using force vital capacity y test. To determine whether there is a different in pulmonary functions base on position in football team such as defense and striker. 1.4 Hypothesis H °-There is no significant different on pulmonary functions in football position such as striker and defense H ª-There is significant different on pulmonary functions in football position such as striker and defense 1.5 Significant of the study The significant of this study is mainly to measure and compare the lung volumes and capacities among the Uitm football player base on their position. Does the football position such as striker position and defenses position have differences effects on the lung volumes and capacities? The study is important because it can help certain peoples such as coach, physiotherapy and athletes especially in any kinds of sports to improve pulmonary functions. In addition, this study also can increase knowledge of coach and athletes, and show them how important is to have efficient and strong lung to improves their performances for their sport. 1.6 Delimitation The first delimitation is the number of any kinds of research subjects, which consists thirty (n=30) age range from 19-25 years old will take part in this study. The subjects are selected in the Uitm football team and physically active and all the participants must be healthy. The subjects are divided into two groups of defense and striker. The others delimitation is the subject gender and age. The test will be conduct in Physiology Lab. Limitation In this study, the participants involved may have some experience in vital capacity test. The participants that will be selects in this study will be participating in the lab test by using spirometer. The participation is important in this study because it can affect the results and data if the participants do not cooperate and participate willingly. Besides that, the time constrains also can be one of the factors because the participants have their own schedules and will clash with the test schedules and can not attend the test. In addition, money can be a problem because, there is no sponsored in this study. The daily activities of the participants will not be controlled. Assumption In this study, it can be assumed that all the participants can do and completed the vital capacity test. Thus, I also believe and make sure that all the participants will understand and follow all the instruction given by the technician. The researchers also predict that all the participants are physically active and healthy. The researcher assumed that the test in this study instrumentation was appropriate for the target population. I also predict that all the participants fully understood the types of test and method and how to perform it correctly. The research participants accurately of completed the inventory leisure participation and leisure constraints to the best of their ability. Lastly, all the participants are coming from the same populations, which Uitm football team aged 19-25 years old.

Understanding Business Ethics

Explain the implications for the business and stakeholders of a business operating ethically. A stakeholder is a person, group, or organization that has direct or indirect stake in an organization because it can affect or be affected by the organization's actions, objectives, and policies. Key stakeholders in a business organization include creditors, customers, employees, government, owners, suppliers, unions and the community from which the business draws its resources. Tesco is committed to conducting business in an ethical and socially responsible manner. This relates to all aspects of their business, treating employees, customers, suppliers and shareholders in a fair and honest manner and ensuring that there are constant and open channels of communication. Tesco has Codes of Ethics for its employees, which includes a policy on the receipt of gifts and a grievance procedure that covers employment issues. Similar essay: How Does Tesco Communicate With Their Customers Tesco has a confidential telephone help line, Protector Line, for any employee who wishes to raise concerns relating to alleged criminal offences, failure to comply with legal obligations, miscarriages of justice, health and safety, damage to the environment and concealment of any of these issues. These are Tesco’s stakeholders: Customers: The employees hear customers' views on everything from how Tesco are serving them in their stores to their role in the community. Customers are looking to buy products; they are looking for a wide range of products. They also want easy accessibility to the premises and hope to buy quality products at competitive prices. They are really important because they provide the money for the store to be successful. Also an expanding amount of customers mean more profit for the business. Most customers expect fresh fruit and vegetables at high quality for good value. Employees: Employees gives Tesco their feedback through the Viewpoint staff survey, Staff Question Time sessions and their Staff Forum process. May want an increase in pay rise. Employees have a very big interest in Tesco; they have an interest in the business in the form of wages, bonuses, discounts, and holiday pensions. The business may be affected by how well their employees do in customer service. If a customer experiences poor customer service, it is more like that they will tell someone else that if they got a good customer service. Therefore employees need the right type of customer training in order to be successful to the business. Suppliers: Tesco’s core value is â€Å"treat people how we like to be treated†, and it's something they apply firmly to their supplier relationships. Suppliers stock the business with all its business supplies; if they are late then it causes conflict between business and suppliers. Therefore, it is vital that all the business supplies are on time. Suppliers are probably the third important part in a business, they provide the products and if they are not on time it poses a great threat to the financial state of a business. On the other hand, suppliers aren’t that important in decision making because they’re scared of losing their contract with Tesco. The main jobs of the suppliers are to sell fresh stock daily at market price. Investors: Tesco’s Investor Relations team regularly meet analysts from the financial institutions which invest in them or represent their shareholders. In contrast it may want a decrease in pay rise for their employees. The owners are probably one of the most important people in a business, they set rules. More importantly they expect repeat business profits and respectable customers.

Beethoven Sonata No 27 Essay

This piece is highly unusual for Beethoven Sonatas. One, although it was written at the start of his late period, this sonata had only two movements, the first being extremely short. Secondly, this was the first that Beethoven started writing his tempo markings in German, as though implying that this Sonata was more personal. Beethoven has also remarked on this piece that he considered titling it either â€Å"Struggle Between Head and Heart† or â€Å"Conversation with the Beloved†. This sonata was dedicated to Count Moritz von Lichnowsky and so describes the love affair he was having at the time. Beethoven literally gave the Count this sonata with the words, â€Å"This Sonata describes your love life.† The first movement of the sonata has an extremely short development, and a surprising coda. The second movement is much longer, much like a Schubert sonata and has another surprising ending of a small epilogue. In fact, Schubert’s first sonata (unfinished) 2nd movement, shows a distinct likeliness to this piece’s 2nd movement. It would almost seem like Schubert’s first sonata was a tribute to Beethoven. Written in 1814, there is a 5 year gap from his last sonata. He gives exact instructions for his tempo markings because, as he said, â€Å"I am deaf, and I can no longer play the piano. Therefore, I must give exact instructions to the performer.† In fact, he became so particular, that he started notating exactly where his dynamic changes are, leaving almost no room for the performer for adjustments. Listening to a lecture recital by Andrea Schiff, he has remarked that Sonata no. 27 is one of the most mysterious of the 32 sonatas. This sonata was written deliberately not to ‘please’ his audience. He wrote it to promote discussion among music lovers and pianists. This sonata wasn’t even written to be performed on stage. Both movements of this piece end quietly, written subito piano and no retardando could be seen. The piece ends quietly and the audience is barely aware the piece has even ended. This sonata is not meant to make an impression. Andrea Schiff has even gone so far to say that, â€Å"Ideally, we wouldn’t even have an applause at the end of this piece, there is nothing to applaud!† Furthermore, the sonata after, No. 28 (in A Major), sounds like a continuation of the 2nd movement. I will be doing a structural analysis of the Sonata, however, I will also be adding some commentary on some aspects I find more interesting. Starting from the beginning of the first movement, we have the exposition and the first theme. Already here in the first eight bars we can see the conflict â€Å"between the head and heart†, like this movement is so aptly nicknamed. In m. 8-16, we see some use of syncopation, indicating that the movement should be counted in one and not three in the  ¾ time signature. In the first 24 measures, ending with the fermata on a rest, we see clearly the backbone of the whole sonata. In the next section starting with an open b octave, we see the composer has marked in tempo and pp. Beethoven really marks everything for the performer, leaving little to question on how exactly he wants it performed. In m. 55, where we have a very awkward left hand broken chords, I would like to point out that the base line for these seemingly randomly spaced chords is actually the inversion of the original theme at the beginning of the piece. The second movement starts at m. 82 on a single b. At m. 109, we have a sudden reminiscence of polyphonic texture much like what Bach would have written. Starting in m. 113, just when the counterpoint ends, we see that the theme has migrated to the tenor line in the left hand, leaving the right hand free to ‘improvise’ over. We modulate at m. 130 and in m. 136 there is an echo of the first theme. Just when we think that it sounds somehow familiar, the recapitulation suddenly appears at m.144. There is a little coda at m. 231 and the first movement ends quietly with no retardando marked. It is assumed that the performer moves immediately to the 2nd movement. The opening theme in the rondo is something that the performer becomes familiar with very quickly, because it is repeated in the entire movement no less than sixteen times. In contrast to the fighting between the head and heart in the first movement, this movement is nicknamed, â€Å"Conversation with the Beloved†. This theme is so unlike Beethoven that it has almost a Schubert-like quality to it. I would also like to note that the opening theme of the second movement is an inversion of the first theme in the first movement. The epilogue at m. 286 quietly ends the piece, just slipping away. No one notices that it has ended until the surprising silence occupies the space. There is no retardando written and the dynamic marking is pp. I would also like to do a Golden Mean analysis with the first movement, the second movement, and the entire work. Movement one: 145m x .618 = 89.61 Movement two: 290m x .618 = 179.22 Whole work: 535m x..618 = 330.63 or 185.63 in the 2nd movement In movement one, the midpoint falls a few measures after the development, where the theme is being repeated in the surprising key of a minor. This is right before we crescendo up to a climax at m. 92. In movement two, the midpoint falls onto another a minor chord. This measure is right before we transition to another choral in the key of B Major. The midpoint of the entire piece falls on an unassuming measure in the middle of the first theme of the second movement. As for the most important parts of the entire work, I would point out the interesting inversions scattered across the board. First would be the awkward broken chords at m. 55 in the first movement that I have mentioned before. And then again right before the recapitulation when the theme is echoed over the keys. Then again at the little coda at m. 231. As for the second movement, the whole theme is the inverted first theme of the first movement.

Salem Witch Trials and True Essence - 1123 Words

Crucible Essay Throughout the novel The Crucible, Arthur Miller describes how being put thought the Salem witch trials of 1692 brought out the true essence of various characters. Arthur Miller shows that the various victims who were put through trials would confess to save themselves and also the difficulties they had to face during their trial period. Characters like John Proctor, Giles Corey, and Reverend Hale were put through different kinds of trials each different from the others. Each of these trials brings out the true essence of the characters and how the characters have changed since the beginning of the play. Through the plays actions and dialogue, Miller suggests that sacrifices may be necessary to restore the social†¦show more content†¦I mentioned my wifes name once and Ill burn in hell long enough for that. I stand mute.† Giles is then trialed for not giving the name and contempt of court. Giles has a choice whether to give the name and save himself or keep it to himself and not get anyone’s name. Giles keeps it to himself but the court doesn’t find this fair so they put heavy stones on him until he answers. Giles only words are â€Å"more weight† which shows how he goes from talkative to a very quiet person. Giles goes from comical to a serious person trying to save others from the injustice of the court. Giles was another example of character whose true essence is revealed through the trials. Another fine example the Arthur Miller gives us of a character who changes when put into a trail is Reverend Hale. Hale comes to Salem strongly believing their will be witches in Salem and that they will eradicate the ones who are witches. Hale believes that his books on the supernatural are quite accurate so all his answers that he forms lead him to believe in the supernatural. After Hale hears Proctor’s and Mary Warren’s story Hale begins to figure out that the trials are just a hoax. Afterwards Hale tri es to tell Danforth that the victims are only confessing because they want to live. Danforth doesn’t believe Hale and Hale is frustrated and leaves, but returns in Act IV.
