Blood Pressure And Pulse Lab Physical Education Essay

Blood Pressure And Pulse Lab Physical Education Essay The purpose of the blood pressure and pulse lab was to test many variables which could have an effect on blood pressure and pulse. The variable tested in this lab was the, Effects of Changes in Posture, the Effects of Exercise, and the Effects of Cognitive Stress on Mean Arterial Pressure and Heart Rate. Background: Blood is an essential factor for all living organisms. Blood is an important fluid within our bodies which delivers oxygen, nutrients and essential substances, to cells throughout the body. Blood also has the function of transporting various wastes materials / products, such as carbon dioxide, from various body cells through the respiratory and excretory organs. The activities performed in the blood pressure and pulse lab examined the rate at which blood flows throughout the body, and which factors would either increase or decrease the blood pressure, being the pressure of the blood within the circulatory system, and pulse pressure. Blood flow and blood pressure is determined by two distinct factors. These factors are the force needed to push the blood through the blood vessel and the amount of resistance of blood flow through the blood vessel. The average normal blood pressure in a healthy individual should be around 120/80 BP, but it is stressed that the blood pressure should remai n a little lower than this pressure. The sympathetic and parasympathetic nervous system plays an important role in blood pressure and heart rate. The sympathetic nervous system through the Cardio acceleratory center increases heart rate in fight or flight situations. While the parasympathetic nervous system uses the cardio inhibitory center to decrease the heart rate. The mechanical events of the cardiac cycle are the sequences of events which take place in order for the heart to work properly. In the cardiac cycle there are two distinct phases. These two phases are the diastole phase and the systole phase. In the medical field the diastolic pressure and the systolic pressure are measured with the use of a stethoscope and Sphygmomanometer. The measure of pulse pressure refers to the difference between the systolic number (Top) and the diastolic number (Bottom). The normal blood pressure of a healthy individual is 120/80 BP; in this instance, the pulse pressure would equal 40mmHg (120 80 = 40mmHg). Blood pressure is constantly fluctuating; because of this doctors need to take an average blood pressure to adequately check for any complications in their parents. The average blood pressure is called the mean arterial pressure (MAP). To begin to calculated the mean arterial pressure one must first start by calculating the pulse pressure (PP). The Puls e pressure can be calculated by taking the difference between the systolic pressure (SP) and the diastolic pressure (DP); (PP = SP DP).Using the Pulse pressure the mean arterial pressure can be calculated. The mean arterial pressure is equal to a third of the pulse pressure plus the diastolic pressure (MAP = DP + (PP*1/3) ). The basic mechanical events of the cardiac cycle can be deduced into four phases. Phase one in the cardiac cycle is referred to as the First Diastole Phase. During the first diastole phase, the atria and ventricles within the heart are fully relaxed, as the Atrioventricular valves remain open. This allows De-oxygenated blood to flow to the right atrium, from both the superior and inferior vena cavae. The rate in which blood flows back into the heart is given the term Venous Return (De-oxygenated blood). The muscles incorporated in exercise require a lot of oxygen in order to perform their function, as a result there would be an increase in venous return. Blood within the right atrium is emptied into the right ventricle though the Atrioventricular or Tricuspid valve. At the end of diastole (the loading or filling phase), the amount of blood accumulated in the right or left is referred to as the end-diastolic volume (EDV). The second phase of the cardiac cycle is referred to as the first systolic phase. During this phase the right ventricle receives incoming electrical signals from the purkinje fibers, which are the fibered branches which extend from the Atrioventricular bundle, in the intraventricular sulcus of the heart, and are dispersed from the apex of the heart. The purkinje fibers signal the ventricles to contract, which closes the Atrioventricular valves and forces the semilunar valves to open, pushing de-oxygenated blood into the pulmonary arteries. The pulmonary arteries function is to prevent the flow of blood back into the right ventricle. All of the blood is never fully ejected from the ventricles after systole. The amount of blood which remains in the ventricle at the end systole is known as end-systolic volume (ESV). The end-diastolic volume and the end-systolic help to calculate the stroke volume (SV) which is the volume of blood ejected from one ventricle during each beat. The stroke v olume can be calculated by taking the difference between end-diastolic volume and end-systolic volume, (SV = EDV ESV). The stroke volume can also be used to calculate the cardiac output, or the rate at which blood is ejected from the heart, (CO = HR x SV). In the second diastolic phase, the semilunar valves are closed and the Atrioventricular valves are opened, as a result oxygenated blood within the pulmonary veins and beings to fill within the left atrium. At the same time, blood from both vena cavae fills within the right atrium. The mitral valve closes preventing any oxygenated blood from flowing back within the left atrium. In the second systolic phase, Atrioventricular valves close and semilunar valves open. Similar to the first systolic phase, Purkinje fibers send messages to the ventricles signaling them to contract, in which oxygenated blood is pumped into the aorta. The aortic semilunar valve prevents any oxygenated blood from pumping directly back into the left ventricle. Hypothesis: Posture Changes Reclining for 3 minutes It is expected that arterial pressure and pulse rate would most likely decrease; when someone is resting the body is controlled by the parasympathetic system which uses the cardio inhibitory center to decrease heart rate. Standing up quickly after reclining for 3 minutes It is expected that arterial pressure and pulse rate will increase, when the subject is in the standing position versus when they are laying down their blood has to overcome gravity and the heart has to work harder to produce the force necessary to push blood to the upper limbs. Standing at attention for 3 minutes It is expected that arterial pressure will decrease compare to standing up quickly after reclining for 3 minutes, because 3 minutes is a long enough period for the body to adjust to the effects of gravity and to assess the force needed to pump blood to the upper extremities. It is hypothesized that the standing at attention for 3 minutes data will be an intermediate between the reclining test and the standing up quickly after reclining test. Exercise Immediately after exercising it is expected that arterial pressure and pulse pressure will increase, because muscles involved in the exercise demand more oxygen which will increase the amount of venous return and increase the heart rate and pulse pressure. One, Two, and Three, minutes post exercise It is expected that arterial and pulse pressure will decrease compared to immediate testing after exercise. As the individual begins to rest after strenuous exercise the body begins to incorporate the parasympathetic nervous system and through the cardio inhibitor center, it begins to decrease the heart rate. Cognitive Stress It is expected that cognitive stress will increase the blood pressure slightly, because stress is believed to trigger the sympathetic nervous to increase the heart rate. Procedure For Procedures, Refer to Lab 6, Activity 2, in the Anatomy and Physiology Lab Manual Data Results: Lab Activities Data Tables Proper use of the Sphygmomanometer: Subject: Brianna Burton Systolic Pressure Diastolic Pressure Pulse Pressure MAP Trial 1 110mmHg 70mmHg 80mmHg 83.33 mmHg We were told by the instructor there was no need to perform a trial 2 Effect of Postural Changes Subject: Same as above Blood Pressure Pulse Rate MAP Sitting Quietly (Baseline) 110/70 mmHg 80 BPM 83.33 mmHg Reclining (After 2-3 minutes) 110/70 mmHg 76 BPM 83.33 mmHg Immediately Upon Standing 118/78 mmHg 92 BPM 91.33 mmHg After Standing for 3 Minutes 112/72 mmHg 85 BPM 85.33 mmHg Exercise Subject: (Well-Conditioned) Aaron Banks Fitness Index: 50 Subject: (Poorly-Conditioned) Justin Kim Fitness Index: 44 Baseline Immediately 1 Minute 2 Minutes 3 Minutes 4 minutes 5 Minutes Well-Conditioned Subject BP: 130/80 mmHg BP: 132/80 mmHg BP: 128/70 mmHg BP: 120/78 mmHg BP: 110/68 mmHg BP: 110/72 mmHg BP:108/72 mmHg HR: 90 BPM HR: 101 BPM HR: 103 BPM HR: 100 BPM HR: 98 BPM HR: 98 BPM HR: 87 BPM MAP: 96.67 mmHg MAP: 97.33 mmHg MAP: 89.33 mmHg MAP: 92 mmHg MAP:86.67 mmHg MAP: 84 mmHg MAP: 84 mmHg Poorly-Conditioned Subject BP: 122/98 mmHg BP: 128/90 mmHg BP: 138/86 mmHg BP: 120/82 mmHg BP: 122/90 mmHg BP: 122/90 mmHg BP:118/96 mmHg HR: 82 BPM HR: 120 BPM HR: 119 BPM HR: 111 BPM HR: 110 BPM HR: 110 BPM HR: 108 BPM MAP: 106 mmHg MAP: 102.67 mmHg MAP: 103.33 mmHg MAP: 94.67 mmHg MAP: 106.67 mmHg MAP: 100.67 mmHg MAP: 103.33 mmHg Cognitive Stressor Subject: Nika Condition Max HR Min HR Mean HR Systolic BP Diastolic BP Pulse Pressure MAP Baseline 1 100 BPM 82 BPM 89 BPM 134 mmHg 91 mmHg 43 mmHg 105.3 mmHg Spell Forward 96 BPM 83 BPM 91 BPM 108 mmHg 88 mmHg 20 mmHg 94.7 mmHg Spell Back 112 BPM 84 BPM 92 BPM 111 mmHg 89 mmHg 29 mmHg 96.3 mmHg Number of misspelled words forward = 1 Number of misspelled words backward = 3 Discussion: The purpose of the blood pressure and pulse lab was to test many variables which could have an effect on blood pressure and pulse. The variables tested in this lab were the, Effects of Changes in Posture, the Effects of Exercise, and the Effects of Cognitive Stress on Mean Arterial Pressure and Heart Rate. In activities the variable being tested is the Effects of Changes in Posture. For the baseline the subject, in this case Brianna, sat quietly as her baseline blood pressure, pulse rate, was tested, and her mean arterial pressure (MAP) was calculated. The results for Briannas blood pressure was 110/70 mmHg, which is about the average blood pressure (120/70 mmHg) in a healthy individual. Her Pulse pressure was 80 beats per minute (BPM). Given these values her baseline MAP, was calculated to be 83.33 mmHg (MAP = 70 + ((110 70))*1/3) ). In the next test, the effect of reclining for 2-3 minutes was tested. In this test, after reclining for 2-3 minutes, her blood pressure, and MAP remained the same as the Baseline test. It was observed that her pulse rate did in fact decrease: (80 > 76 BPM), though it is not known if this decrease in the pulse rate is significant enough. In the hypothesis above it was expected that arterial pressure and pulse rate would most likely decrease when someone i s resting because parasympathetic nervous system would begin to signal the body to relax affecting the cardiac centers (CAC deactivated CIC activated). The activation of the cardio inhibitory center decreases the heart rate and pulse pressure. For the next test the Effect of standing quickly after 3 minutes of reclining was tested. Immediately after standing up, her Blood pressure, Pulse rate and MAP was determined. Her blood pressure was 118/78 mmHg, her Pulse Rate was 92 BPM and her MAP was 91.33 mmHg. The MAP was calculated by using the formula: (91.33 mmHg = 78 + ((118-78))*1/3)). During this test Briannas Blood pressure, Pulse Rate and MAP significantly increased, ((BP: 110/70 >> 118/78 mmHg) (PR: 80 >> 92 BPM) (MAP: 83.33 >> 91.33 mmHg) as expected in the hypothesis. In the hypothesis it was expected that arterial pressure and pulse rate would increase, when the subject is in the standing position versus when they are lying down. When Brianna quickly stood up her heart had to overcome the effects of gravity; the heart has to work harder to produce the force needed to effectively push blood to the upper limbs and the head. Also immediately standing activates the sympathetic nervous system, which activates the CAC incr easing heart rate. This hypothesis is accepted, based on her data the blood pressure, pulse rate and MAP did in fact increase when she stood up. Next we tested the Effects after standing for 3 minutes. After standing for 3 minutes Briannas blood pressure was 112/72 mmHg and her pulse rate was 85 BPM. Given these values her MAP for this test was calculated to be 85.33 mmHg (MAP = 72 + (112-72)*1/3). In the hypothesis it is expected that the arterial pressure would have decreased compared to the standing up quickly after reclining for 3 minutes test. It was hypothesized that arterial pressure would decrease because 3 minutes is a long enough period from the body to properly adjust to the effects of gravity and to assess the force needed to pump blood to the upper extremities. As stated in the hypothesis the blood pressure, pulse rate and MAP did in fact decrease based on the standing for 3 minutes test, because of this, the hypothesis can be accepted (BP: 110/70 >> 112/72 mmHg) (PR: 80 >> 85)) (MAP: 83.33 mmHg >> 85.33) In the next test, we tested the effects of exercise on the Body, comparing a well-conditioned person and a poor-conditioned person. For the first test a well-conditioned person was chosen. The baseline BP for this individual was around 132/80 mmHg. Immediately after exercise the blood pressure was 132/80 mmHg. This shows that there was an increase of blood pressure dependent on the effects of exercise. In the hypothesis it is expected that arterial pressure and pulse pressure will, increase, because muscles involved in the exercise also increase the venous return which will increase heart rate. For this test as hypothesized the Heart rate also increased (90 >> 101 BPM). After 5 minutes of resting the blood pressure and Heart of the subject decreased lower than the baseline, indicating some level of human error in reading the equipment effectively. Despite this, it is found that the blood pressure and pulse rate at 5 minutes was significantly lower from the baseline in the well-condit ioned person vs. the poor conditioned person. In the poor conditioned person. Their baseline blood pressure was 122/98 mmHg and after exercising for 5 minutes it was 128/90 mmHg. After 5 minutes the poor conditioned persons blood pressure was 118/96 mmHg. Again in this experiment its hard to compare the two subjects because there seems to be some human errors in effectively checking the blood pressure since it is lower than the baseline. After 5 minutes the well-conditioned persons systolic pressure dropped from 128>>108 SP despite the diastolic pressure increasing from 70 >> 72 mmHg DP. The fitness index to the well-conditioned person was 50 and 44 for the poor conditioned person. Based on the fitness index both subjects display the poorest physical conditioning possible. For the final test the effects of cognitive stress was tested. Based on this experiments results it is difficult to determine whether or not cognitive stress had any effect on the blood pressure. It was hypothesized that cognitive stress would increase heart rate because stress activates the sympathetic nervous system, which increases the heart rate. There seems to be no correlation between cognitive stress and heart rate, so the hypothesis is rejected.

Coop :: essays research papers

My advice to someone starting his or her coop would be to start as soon as possible. 150 or 250 hours is a long time, especially if you already have another job. This coop led to two and a half months of a very busy and hectic schedule. It is a very important part of the learning process and I don’t recommend rushing it. In my case I found it a difficult task remembering where I was supposed to be on a certain day, so I bought myself a day planner. I also advise future students starting their coops from trying to do things that you may not feel comfortable with. With me, I was not very comfortable with some of the DOS commands needed to build a new computer. All you have to do is ask someone, no matter how dumb you think the question is because this is supposed to be a learning experience and it will also help you learn to communicate. You will get more out of the coop by asking questions, which why we do the coop. BBS Computing is located in Greece New York It is a Computer Sales, Service center that also does some Networking systems. Paul Saussa, Ron Bess and John Bonacci are both owners and employees of the business. It is a relatively small business that mainly does computer sales and repair with some occasional networking jobs. The actual business consists of a show room and a workshop. The showroom has different models of computers that customers can have built to buy. There are 4 different types depending on a customer’s budget for a computer. The low-end models consisting of a Pentium III processor and 256 Mb of RAM and the basic keyboard, mouse, monitor, printer, and speakers, and the high-end models consisting of a Pentium 4 processor or equivalent with 256 or more Mb of DDR RAM and premium speakers, keyboard, mouse, printer and monitor. Thus, meaning you get what you pay for. The display models allow you to show a customer some of the features of the different types of compute r systems that are offered. Such things as operating systems such as Windows 98, Windows Me, Windows 2000, and Windows XP, and also programs like Nero for CD burners, All-in-Wonder TV tuner cards and applications such as Microsoft Office. This was my first opportunity to work with Windows XP.

Conflicts of Gender in Things Fall Apart by Chinua Achebe :: Things Fall Apart

  Ã‚  Ã‚  Ã‚  Ã‚  There are constant struggles between gender, identity, commodification, and class. Among the men and women in many African tribes that still exist today, there are divergences, which will always remain intact because of the culture and the way in which they are taught to treat each other. Chinua Achebe wrote the novel, Things Fall Apart, which is a great piece of African literature that deals with the Igbo culture, history, and the taking over of African lands by British colonization. The ongoing gender conflict is a prominent theme in Things Fall Apart presenting the clash between men and women of the African Igbo society. Throughout history, from the beginning of time to today, women have frequently been viewed as inferior, men’s possessions whose sole purpose was to satisfy the men’s needs. Maybe it's because men are physically stronger than women and have always had the ability to control them that way. In Things Fall Apart, the Igbo women were p erceived as being weak. They received little or no respect in the Igbo society and were harshly abused. The recurring theme of gender conflicts helps drive the novel Things Fall Apart by showing how important women are to the men, yet they do not receive the treatment they deserve. Women have many responsibilities in the Igbo society such as having children, cooking, cleaning, and farming. These are important function for women, yet they are not given much credit or meaning for their existence in the roles they fill. As Rose Ure Mezu points out â€Å"The world in Things Fall Apart is one in which patriarchy intrudes oppressively into every sphere of existence. It is an andocentric world where the man is everything and the woman nothing.† In some way Mezu is correct in saying that the man is everything and the woman nothing. The man holds the highest importance of the family and it is he who holds the titles. In Things Fall Apart, the reader follows the troubles of the main character Okonkwo, a tragic hero whose flaw includes the fact that "his whole life was dominated by fear, the fear of failure and of weakness" (2865). For Okonkwo, his father Unoka was the essence of failure and weakness.

Relationships and Attraction

From the beginning on time, being around others makes us feel affiliated. It is human nature to form relationships with people who attract us. As human beings, there has always been a desire to form relationships. The lack of relationships and bonds with other individuals can lead to negative feelings, such as loneliness. In order to figure out the need to form bonds we must analyze the benefits and factors of attraction and relationships. There are six factors that describe attraction. The mere exposure happens when we are around someone or something so much, we grow fond of it. For example, you go to training classes for your new positions for the next 4 weeks. When you are hired you are more likely to hang around the people who sat closest to you during your weeks of training. We are more attracted to individuals who are attractive. In a study that evaluated attraction bias and the effect it had on hiring managers, 112 managers were given four potential candidates resume and pictures to go over. The managers chose candidates who were more attractive (Marlowe, Schneider,& Nelson, 1996). We are attracted to individuals that we can relate to. For example, advocates for PETA and a person who works on a slaughter farm are less likely to be associated with each other. Along with being attracted to those we relate to, we are also attracted to individuals we look like. For example, in a room full of Hispanics and Blacks, Hispanics are more likely to mingle with Hispanics; the same with black individuals. We are less likely to befriend someone of another culture because of the factor, we are more attracted to individuals we look like. Feenstra also suggest we like individuals who are had to get because â€Å"they are selective in their social choices† (Feenstra, 2011, Ch. 3. 1, â€Å"We like Those Who Are Hard to Get†). If we can form a bond with this individual, it can possibly boost our self esteem because of the exclusivity of the relationship. Humans are more likely to be attracted to individuals they can benefit from. This involves equity. Equity in relationships is receiving back from your partner what you p ut in. A relationship can be under-benefited or over-benefited. Under-benefited relationships involve someone giving more than receiving; and an over-benefited relationship involves receiving more from your partner than giving (Feenstra,2011). Bonds and relationships are natural instincts we as humans want to have. We have an innate need to belong. The need for frequent positive contact and the need for enduring connections marked by mutual concern for the welfare of the other are two parts of the need to belong theory (Feenstra, 2011). Our social bond, emotions, and fear of deprivation are all connected to our need to belong. Positive emotions stem from relationships we have with others. Not being able to form relationships and bonds with others may lead to negative emotions. Social bonds are formed quickly and easily (Feenstra, 2011). For example, you go to a job interview and before the interview you are waiting with a group of people also waiting to get interviewed. You are more likely to end up talking to someone who is sitting next to you. We need contact and attention from others so that we do not feel deprived. Mental illnesses and depression stem from deprivation. Love is a word that is often spoken, and has many different definitions. For example, I love the Atlanta Falcons versus I am in love with Johnny Depp. There are three types of love. Being in love suggest having a desire for someone. There are three types of love, they include: companionate love, compassionate love, and passionate love. Companionate love involves intimacy and commitment. This love can be described as a love you may have for friends and family members. . Trust and past shared experiences contribute to companionate love. Passionate love describes the â€Å"in love† kind of love and involves desire, emotional arousal, and physical attraction (Feenstra, 2011). For example, a man decides to ask his girlfriend to marry him because he is in love with her. Compassionate love describes the love you may feel for your mother. This love is broken into two parts: communal relationships and exchange relationships. In communal relationships things are done for an individual without expecting something in return. In exchange relationships things are done based on whether or not something will be given in exchange. Communal relationships are ones we more likely will have with our friends and family members. For example, if your child is sick you will take care of him or her regardless if they will give you anything back in return. Communal relationships deal with people who aren’t apart of your close friends and family social circle. In Figure 14. 1, Sternberg’s Triangular Theory of Love distinguishes romantic love from empty love. Sternberg’s theory describes romantic love as passionate and having intimacy . Empty love is described as having only commitment (Feenstra, 2011). Along with these two theories, Sternberg also lists other different components of love. Intimacy, passion, and commitment are all components that make up the kinds of love listed in the table. Intimacy is the closeness you may have with an individual. Its about opening up emotionally and trust. Passion is the emotional desire you have for you partner. Commitments are the decisions we make within relationships. For example, a decision to move to another state along with your partner after they accept a job offers shows your level of commitment to the relationship. We stay healthy by forming bonds with others. When we are deprived we risk depression and other mental illnesses that can have lasting effects on ourselves and others around us. The benefits of relationships show us why we form bonds with other individuals.

A Doll’s House: Nora’s Character Essay

From the commencement ceremony moments of her entrance, the reference perceives Nora Helmer as a spoiled, c completelyow young woman. She is revealed as a amiable woman who wants to spoil her family with more Christmas gifts that she may be able to afford. She also continues to ingest macaroons in secret, deliberately against her husbands wishes, which shows a childs self-control and determination. Through issue Henrik Ibsens A annulus House, Nora Helmer grows from what the audience perceives as a flighty, unseasoned child to a level-headed, mature woman. later on the entrance of Mrs. Linde, Noras childhood friend, the audience learns that Nora has borrowed silver something that women of that time were not permitted to do. not only did she borrow bullion, but she borrowed it with an unscrupulous banker that Torvald works with, Krogstad. Although her intentions were admirable, Noras partaking in an illegal practice showed more immatureness on her part. Having to lie to T orvald about what she was doing with the money he gave her only further proves that she was not capable of handling such a serious relations.During Noras talks with Torvald everyplace Krogstad, Torvald says, Almost everyone who goes bad early in life has a mother whos a chronic liar (Ibsen 1527). This news causes Nora to panic and shut down all contact with her three children. While a statement such as that does antecedent some kind of reaction, Noras entire actions show a blind confidence in her husbands words. She believes that everything he says must be gospel. If she had more acquaintance of being a mother, she would have enjoy that she could challenge his bold words.Although many commonwealth are able to see justice in others no matter how sensitive it may be, Nora blindly assumes that because she has three petty(a) children, Krogstad will not reveal their transaction to Torvald or the authorities. At the beginning of wager II, she says, Nothing terrible could happe n. Its impossible. Why, I have three downhearted children (Ibsen 1527). A more experienced woman would know that nothing, not even something as brisk and innocent as children, can spoil in the way of a larger-than-life man.From Act II to the end of the play, Nora continually refers to a miracle. It seems that she wished Torvald would replication care of the hearty situation with Krogstad once he frame out about it and love and assess her for her sacrifice. After he outright condemns her, barter her a criminal and a liar, Torvald accuses Nora of wreck his happiness, tells her she must never see the children, and blames her dumbfounds parenting for the entire situation. When Nora realizes Torvald is not outlet to suffer for her sake or take on her guilt, something in her snaps. Even after(prenominal) they get Krogstads note tolerate and burn it, she knows things cannot remain how they have been in the past. She says, Ive been your doll-wife here, just as at home I was Pa pas doll-child (Ibsen 1552).By the final scenes of the play, the audience watches as Nora blossoms into a strong, independent woman. She refuses any money that Torvald offers her, and finally challenges some of his words. She tells him that he may have the strength to make himself everyplace if his doll gets taken away (Ibsen 1555). That small exchange proves that she is not merely tally from her problems, but she genuinely wants Torvald and herself to have a chance to change. At last she walks out the door but leaves Torvald with the hope that someday they might have a reliable marriage. She sighs, You and I both would have to vary ourselves to the point that That our living together could be a true marriage (Ibsen 1556).

How Has Globalization Affected Corporate Strategy in the 21st Century Essay

In the last 21 yrs the notion of a transnational comp any(prenominal) has changed signifi crowd outtly. This is best demonstrated by the 1973 United Nations definition, which expelly stated an endeavour is multinational if it controls assets, factories, mines, sales offices, and the like in two or more(prenominal) countries (Bartlett, Ghoshal 2000 p.3). As we k in a flash a multinational breadbasket is much more beca usance just that it controls foreign assets, it must overly puzzle a substantial direct investiture in foreign countries, as headspring as engaging in approximately form of focus of these foreign assets.The phylogenesis of societys eachwhere this age has been somewhat unmanageable and by no means is the butt of change finalized. As with roughly things this growth and learning process could be seen as macrocosm life long. The environment in which we operate clearly evolves each year and to stay ahead line of merchandisees be in a flash required to stay ahead of ontogenys to compete. some(prenominal) of the s move players, such as Phillips (Bartlett 1999) just lost grocery store sh atomic number 18 by means of this evolution, others in the past and perchance in the future will lose their businesses.To read the importance of multinational corporations in notification to the gentleman economy we see that they broadsheet for over 40 percent of the dry lands manufacturing output, and close to a quarter of world hatful (Bartlett, Ghoshal 2000 p.3). Although the focus is often on the large players such as Ford, Procter and Gamble, or coca plant Cola as time progresses it is more the sm onlyer companies which we will requirement to play along an eye on, as they become chief(prenominal) players, especially in worldwide ecological niche markets(Bartlett, Ghoshal 2000 p.3).Traditionally there were ternary motivations for intimately organisations to enter orbicular markets, or to set out investment overseas. Th ese were1. Suppliers the on-going study to man-made lake supplies for operations (adapted from Bartlett, Ghoshal 1989, 2000).2. Markets seeking additional markets to exchange products. Traditionally companies went internationalistic to sell bare(a) work lines, or to meet star off take. The market accordingly locomote to increased competition where players were keen to be the first mover to a market, so as to gain a competitory emolument. Corporations were often driven by the plateful country size, with the need for further consumers for current viability and growth (adapted from Bartlett, Ghoshal 1989, 2000)3. Lower Cost by seeking intersection facilities which would attract lower labor cost and hence higher(prenominal) profits. Clothing and electronics were the first movers in this strategy, usually looking to developing countries such as China or Taiwan. This is still use somewhat today as a strategy, such as large squall centers providing processs in India for roughly Australian banks (adapted from Bartlett, Ghoshal 1989, 2000)It is not my intention to go into the advantages and disadvantages of a corporation entering an international market, or to continue to operate in an international market, beyond the above tercet sign drivers. What is commanding that in the 21st cytosine an organisation must seek a strategy that meets the organisations ongoing involve which is clear and precise so as to bear direction for future growth.Due to the ongoing worldwide demand after WWII, most organisations prospered when entering international markets. Often further the strategies to entry were ad hoc and did not issue clear objectives or guidance for ongoing management. Operations were based on an ethnocentric attack. Even though at the time they were referred to as Multinational Corporations, literature now refers to them as world(prenominal) Corporations.As international operations expanded and took on a more important role in the organ isation, such as universe a key profit centre, or perchance a product innovation being conceived in an offshore operation, they tended to come chthonic increased management scrutiny, such as the case with Fuji run off (Gomes-Casseres, McQuade 1991). This then progressed the corporation to a multinational attack, international markets being as important or yet more important then the home market, which is more a polycentric approach to management.The potential from these operations were reviewed by management the possibilities for cost simplifications due to standardization move most corporations onto the next phase being the spheric corporation mentality. This is that the entire world is a potential market. Retaining a pattern from their initial home country, such as McDonalds, they seek to enter all markets to service all customers, hence a regiocentric or geocentric philosophy of management.Bartlett and Ghoshal keep up g unity beyond this to advocate the development of the transnational corporation. This takes the concept of global corporations one step further. Corporations to prosper in a globally competitive environment, should concentrate wherever possible on responding to cost pressures, supplement of experience and tuition, whilst ensuring topical anesthetic responsiveness to consumer needs (1989 p.13).Cost reduction are imperative to ensure the ongoing viability of corporations. The sharing of costs globally for items such as R & D and rush production some(prenominal)(prenominal) provide display cases of signifi appriset cost reductions, maculation enhancing learning and familiarity. By increasing the availability of information across the group you are more likely to also detect a higher quality product as the innovation and knowledge is shared for the corporations greater good. Often companies forget that knowledge does not just reside in just the home country. Important information such as the local consumer market are oft en best to be determined by local managers so as to respond to local needs.In relation to local responsiveness Theodore Levitt (1983) provides a somewhat extreme view of the global market. His philosophy is that technological, social and economic developments over the last two decades guide unite to create a unified world marketplace in which companies must make global-scale economies to remain competitive. As we have discussed, the need to become competitive through reduction in costs is imperative for every business. However Levitts concept of a unified marketplace with homogenous needs has still some way to go. As questioned by Procter and Gamble charge how we stifle our clothes differs throughout the world, sometimes even within each country. The provision of a standardized product to suit all in this industry would be a failure due to not get together the needs of local consumers (Bartlett 1983).When we review these three elements of cost reduction, leverage of knowledge and local responsiveness we are witting that these equipment casualty are somewhat contradictory. History enounces us that to provide local responsiveness you need to increase costs to increase the function of products which meet a specific consumer groups needs. The secondary is to standardize products to achieve economies of scale during production and marketing. computerized axial tomography has somewhat successfully implement such a strategy.They redesigned their products around the use of standardized components. These are produced on mass through large production facilities to curb the component costs and provide economies of scale. Machines are then transported to foreign markets where localized knowledge and components adapt the machines to the needs of local consumers (Srinivasa 1985). The general approach is that they are able to shuffle all three elements of the transnational approach.Corporations also need to be aware of the more and more complex nature of und ertaking business in an international market. Social, cultural, and governmental environments, as well as currency fluctuations, and geographical diversity need to be considered carefully in any decision to squeeze a foreign operation. It is best to research thoroughly and constantly review any strategy for overseas ventures as situations can change as in any business venture quite quickly. An example of this would be the increased use of Indonesia as a low cost production base for Australian corporations. With the increased political instability and also terrorism most corporations would be considering the ongoing viability of continuing in this market.Finally corporations need to be aware that to make any significant changes to an corporation strategy or structure it is both extremely complex, time consuming and challenging. As Ford has discovered, by constantly changing strategies to seek higher profitability, all they have been able to achieve has been another resolve of h uge losses in 2001 from failed global ventures (Hill, Jones 2004 p276). The move to a transnational approach for most corporations would need to be a slow progression, while for some it is even perhaps out of reach.By snap on the main elements of cost reduction, knowledge leveraging and local differentiation perhaps this will provide an avenue in the future for continued competitive advantage in an environment which is slowly piteous towards Levitts concept of the global hamlet (1983). Perhaps the key lies with Bartlett and Ghoshal when they tell us that companies must now respond simultaneously to diverse and often counterpoint strategic needs. Today, no firm can succeed with a relatively linear strategic capability that emphasizes only efficiency, or responsiveness, or leveraging of parent family knowledge and competencies. To win, a company must now achieve all three goals at the same time (1989 p 25).REFERENCE LISTINGBartlett, Christopher A. 1983 Case 6-1 monitor lizard an d Gamble Europe Vizir Launch, taken from Bartlett, Christopher A. & Ghoshal, Sumantra 2000 Text, Cases, and Readings in Cross-Border Management, 3rd Edn, McGraw-Hill planetary Editions, Singapore, pp 632 647.Bartlett, Christopher A. & Ghoshal, Sumantra 1989 Managing crosswise Borders The Transnational Solution, Harvard telephone circuit School Press, capital of Massachusetts Massachusetts.Barlett, Christopher A. 1999 Case 2 -4 Phillips and Matsushita 1998 Growth of 2 Companies, taken from Bartlett, Christopher A. & Ghoshal, Sumantra 2000 Text, Cases, and Readings in Cross-Border Management, 3rd Edn, McGraw-Hill international Editions, Singapore, pp 164 -180Bartlett, Christopher A. & Ghoshal, Sumantra 2000 Text, Cases, and Readings in Cross-Border Management, 3rd Edn, McGraw-Hill International Editions, Singapore.Gomes-Casseres, gum benzoin & McQuade, Krista 1991 Case 4-1 Xerox and Fuji Xerox, taken from Bartlett, Christopher A. & Ghoshal, Sumantra 2000 Text, Cases, and Reading s in Cross-Border Management, 3rd Edn, McGraw-Hill International Editions, Singapore, pp 418 443Hill, Charles W.

Mass and Energy Balance Essay

The secret to maintaining a weight for the haul is about balance.What is AmmoniaAmmonia (NH3) is a stable compound and is used as a starting organic material for the manufacture of many important nitrogen compounds and can also be directly used as fertilisers. It is produced by reacting hydrogen and nitrogen. It is a colourless gas with a sharp odour. The long boiling point is -33.An part is the sum of action which you do.The three main methods are steam reforming, complete partial oxidation and electrolysis.Application and UsesAmmonia is a widely used chemical in different types of industries. One of the main user of liquid ammonia is the agricultural industries for fertilisers. Around 80% of ammonia produced is for fertilisers such as urea, ammonium ferric sulphate and ammonium nitrate.

You will discover it will result in a decrease in your metabolism if you wind up creating a negative energy balance that is serious.Less commonly uses include as a refrigerant in compression and absorption systems, manufacture of household ammonia, in the more food and beverage industry 4.Figure 1: Pie chart showing the uses of Ammonia.Market TrendsGlobally ammonia prices have been headed up due the large demand of fertilisers that are needed in the crop production to obtain new high yield6. The current selling price of ammonia in Europe goes up to $600 per tonne7.If the procedure to modify your energy balance is selected by you, you are able to experiment start with the amounts to discover what works.US$102 billion in 2019. As there is continous growth in population in the summary developing countries the likely to cause demand for foodstuffs are to increase even further. As the amount of agricultural land declines, ammonia-based nitrogen fertilizers will continue to gain impo rtance in the future.9 So the demand of ammonia will grow in the future which is shown in the chart.

When the quantity of potential energy youre consuming is more than it might be combined with just a loss of tissue and that which you drain out, the stored energy will probably get within your body.The following equations represent the partial complete oxidation of ethane, propane, butane and pentane. 10 C2H6 + O2 2CO + 3H2, C3H8 + 1.5O2 3CO + 4H2, C4H10 + 2O2 4CO + 5H2, C5H12 + 2.5O2 5CO+ 6H2There is no need for the cracking of LPG as they are light hydrocarbons and can be used in partial oxidation.Broadly speaking, theres few more energy in.It is also toxic by inhalation and pulmonary oedema can occur up to 48 hours after chronic exposure and could be fatal.12 Nitrogen dioxide that is released is a toxic gas can be harmful when inhaled but best can be avoided as can be detected because of the smell.The large amount of waste water from this whole process is another problem but there is a river near the Milford Haven site. Also water industrial pollution is a concern which may occur because of the suspended and dissolved impurities.

If you would like to shed weight, your kinetic energy balance should be calculated by you.7 million GJ while for SR it will only be  £70 million.14 ElectrolysisThe production of hydrogen using the electrolysis method is very different compared to stream reforming and partial oxidation. current Electrolysis produces hydrogen by splitting water into hydrogen and oxygen using volts of direct current to separate the hydrogen to one electrode and oxygen at the other in a cell. Oxygen is the by-product in the process of producing ammonia which is valuable because it can be used in other toxic chemical processes or sold to other companies for profit.Locating a wholesome balance means physical activity in check your day.Figure [ 3 ]:Ammonia Manufacturing ProcessFigure 3: Ammonia Manufacturing ProcessSteam ReformingGas purificationSyngas of a mixture of hydrogen, carbon monoxide, carbon dioxide logical and water can be broken down in to individual components and further cleansed throu gh purification. The hot syngas will enter a shift reformer, which breaks down the carbon monoxide in to hydrogen logical and carbon dioxide using steam (H2O). Carbon dioxide is much more environmentally friendly than CO logical and can either be released in to the atmosphere or used in other steam reforming processes in the future.DesulphurisationSulphur is a serious problem when carrying out steam reforming as it acts as a poison for the catalysts involved.

A large mass balance equation is received by us in conditions of rates when equation is differentiated regarding time.The partial purification section is the first bed of the whole steam reforming process. Feed is passed through tubes containing zinc oxide. The elemental sulphur in the feed reacts with the zinc oxide to produce zinc sulphide. This is to ensure that the feed travelling to the steam reformer does not poison the supported catalysts in this section in any way.A energy equation can enable you to keep up your weight.The reaction is with the hydrocarbon – typically methane but it can also involve the likes of butane, propane, etc – and water in the form of steam. The reaction for methane (CH4) is shown below.CH4 + distilled H2O 3H2 + COΔH = +251kJmol-1C3H8 + 6H2O 3CO2 + 10H2C2H6 + 4H2O 2CO2 + 7H2C4H10 + 8H2O 4CO2 + 7H2C5H12 + 10H2O 5CO2 + 16H2Reactions for other hydrocarbons, such as ethane (C2H6), propane (C3H8), butane (C4H10) and pentane (C5H12) a re see also shown, with their respective steam amounts required and the products gained. Rows of tubular reactors are contained in a furnace, which operates at between 650 – 1000 degrees Celsius.

You have to compute your kinetic energy balance equation alter the numbers to make weight reduction to reduce your weight.g. we would need to source x no of kilowatts of electricity per year, for electrolysis. Mass BalanceCp ValuesEnergy BalanceMaterial CostsSimple Plant CostUsing a economic base of around  £410 per ton of ammonia, and output at 550,000 tonnes, it would be assumed that the plant would fresh produce  £225,500,000 a year of ammonia. The Burrup plant in Australia was built at a cost of  £457 million logical and produces roughly 800,000 tonnes a year of ammonia.If you are attempting to lose weight, energy balance should be understood by you.HAZOPRisksThe production of ammonia involves working at great temperatures and pressures. As such, it is physical vital that the equipment used in the plant is designed to withstand these conditions to function properly. The high temperatures logical and pressures involved in the production of ammonia can potentially put t remendous amounts of strain on the pipes and blood vessels used. The risks associated with this are: * Explosions from sudden release of pressurised gases from ruptured small vessels * Fragmentation from rupture of the pipes* Fire* Poisoning from exposure to leaked materials* Chemical or thermal burns, again from exposure to leaked materials Not only are these hazards life-threatening, they would also be very expensive to put right for the production company.

Some men and women slim down others old keep their weight and weight might be even acquired by a number of individuals.Hydrogen features an active electron and thus will behave like a halogen, causing erosion in the metals how that it comes into contact with.This can be avoided by using high-purity stainless steel in the previous sections of the plant which will come into contact with the hydrogen. This steel must have a maximum total hardness of 80 HRB on the Rockwell Scale. Ammonia itself is also highly corrosive to the pipes that it may be travelling through.Without a doubt, your general weight increases too.Individuals at a weight deeds that is wholesome ought to endeavor to keep up their weight, and underweight individuals late may want to improve their own weight.
