Individual Case Analysis - Essay Example The precise ways in which a brand adds value can be recognised through gaining knowledge about the sources of brand equity (Keller, n.d.). In relation to the provided case scenario related to Red Bull, it can be comprehended that the company focused on the aspect of creating brand awareness as well as establishing their brand image. These two facets are the key sources of their brand equity. Development of the source of brand awareness has facilitated Red Bull to develop its brand equity. Red Bull has especially focused on the element of brand recall. Brand recall refers to the customers’ capability to distinguish a particular brand within different circumstances (Keller, n.d.). . With this notion, Red Bull concentrated on designing its products attractively. Moreover, within its growth strategy the company entered new markets by taking a slow method to optimize the anticipation as well as buzz from the company (Das, 2012). This was a key strategy to build brand equity of the company. Moreover, it focused on inventing the aspect of functional energy within the beverage category segment which facilitated it to create a distinct brand image among the customers. It also focused on above-the-line strategy with regard to marketing aspect to draw the attention of its customers. It created an eye-catching logo of two red bulls and a yellow sun. The animated message reinforced the value of Red Bull as a drink that gives an individual ‘wings’ i.e. it energizes the person. This has been the main notion conveyed by the company to its consumers which is the key source of brand equity for the company (Kumar & Robert 1988). Incorporation of a distinct flavour and packaging along with positioning were the other major facets for the company that facilitated it to develop its brand equity. In terms of packaging, under the logo of the company, highlighting the aspect of energy drink was a major consideration by the company. Moreover, it positioned the brand a s revitalizing substance for body and mind. The product started to create a buzz as a mixer element in varied markets, however, the company primarily attempted to go beyond this aspect and appeal to a broader section of consumers especially the young ones (Rehman, 2011). The company also concentred on participating in different events and sporting activities which substantially boosted up its name and logo, which are the imperative elements for success of a company in terms of augmenting its brand equity. Q:2. Analysis of Red Bull’s Marketing Programs in Terms of how it contributes to the Brand’s Equity Red Bull is using uncongenial adverting policies, as it has uniquely positioned itself in the beverage industry. Its distinctive positioning has allowed it to detain a significant amount of brand recognition in different nations. The company focused on creating a sense of mystique amid its customers through its marketing program. It initially focused on word-of-mouth tr aditional method of advertising technique, however, it wanted to spread the awareness of the brand even more (Collins & Rusktad, 2008). Red Bull’s promotion strategies had facilitated it to flourish in the facets of market share, income, and units sold (Sarah, 2009). Exceptional positioning strategies were focused on by the company by targeting high-school and colleges going

A Tale of Two Cities Essay Does strong devotion overpower the will of a good heart? Ernest Defarge, a character in A Tale of Two Cities by Charles Dickens, is no more than a puppet to his wife. Though he does not like the idea of killing innocent people just because they are aristocrats, he refuses to speak up due to fear of confrontation with his wife. Due to his background and life as a slave, Defarge, like many other revolutionaries, dislikes the aristocracy, and has some desire to get revenge. However, he does not truly want these desires to build to the extent that the revolution got to. Ernest Defarge is a man with a good heat, driven to be a catalyst to the revolutionary acts by his strong devotion to the two things he cares about most: his country, and his wife. Paragraph 1: Though many may not see it behind all the terrible things he has done, Ernest Defarge really does have a good heart. Ernest Defarge shows compassion my comforting Gaspard, saying, Be a brave man, my Gaspard! It is better for the poor little plaything to die so, than to live. It has died in a moment without pain. Could it have lived an hour as happily? Defarge didn’t have to make an effort to help him out, but he does. This random act of kindness shows that he does in fact have a good side to him. After the child is run over, the Marquis throws a coin out of the carriage, thinking he can pay for the child’s life, and in return he is â€Å"suddenly disturbed by a coin flying into his carriage†. In this action of throwing the coin back, which is believed to be done by Monsieur Defarge, shows his dislike to the aristocracy, and foreshadows the fact that he will take a stand against it for the good of his country and its people. Monsieur Defarge’s personality differentiates from this sense of kindness when he barks orders at the revolutionaries such as, â€Å"Patriots and friends, we are ready! The Bastille! (214). In opposition to his good heart, Defarge is also the leader of the Revolution. In this part of the book, he, and his fellow revolutionaries, destroy The Bastille, and everything else that happens to be in their path. This completely contradicts the compassion shown from Ernest Defarge earlier in the book, but also shows that there may be something behind his madness. Monsieur Defarge also happens to be an old servant to Dr. Manette, and cares deeply for him, but when it comes to choosing between helping the Doctor, or helping his country, Defarge’s great devotion to France towers over his feelings towards Manette. Do the square thingy with this quote * â€Å"†¦In a hole in the chimney, where a stone has been worked out and replaced, I find a written paper. This is that written paper. I have made it my business to examine some specimens of the writing of Doctor Manette. This is the writing of Doctor Manette. I confide this paper, in the writing of Doctor Manette, to the hands of the President.† This note he found, is of Manette â€Å"(add quote where he condems darnay)† Even though he deeply cared for Manette, he would do anything, literally anything, to help the people of his country. He believes that sentencing Darnay to death is the right thing to do for France, and since he believes that, he will do everything in his power to make it happen. Defarge knew how bad this would hurt Doctor Manette, since Darnay was the Doctor’s son-in-law, but it was his and his wife’s duty to kill all aristocrats, therefore he couldn’t show and mercy. Defarge would even hurt a friend, in order to do what he thinks will help his country. Paragraph 4:  Even though it is kind of hard to see at first, Madame Defarge seems to have a great deal of power over her husband. â€Å"As to thee†, pursued madame, implacably, addressing her husband, â€Å"if if depended on thee-which, happily, it does not, thou wouldst rescue this man even now† Even though Monsieur Defarge wants to help Charles Darnay, she wouldn’t allow it. He wanted to help out the Manette’s and save Darnay, but after the revolutionaries were informed on what the Evermond’s did to Madame Defarge’s family, he was the only one who wanted to show mercy. Due to the fear of confrontation with his wife, he doesn’t speak of saving Darnay again. Ernest Defarge, from A Tale of Two Cities by Charles Dickens is portrayed as a great leader to the revolutionaries, but in reality, he is merely a puppet, with Madame Defarge as his puppeteer. Devotion can be a strong thing, sometimes so strong that it can lock up the kindness of a good heart, and throw away the key.

The Gravity Bong :: The Gravity Bong

The Gravity Bong I was introduced to the gravity bong by a friend. He told me the full name as described to him was the "Afghanistan Gravity Bong". We were sitting around one night and decided to try one out. While I could go into detail concerning the mechanics of the bong's operation, I don't think that is really necessary. The reason it is called a "gravity bong" and not something else is this is what someone called it, that is how they described it to their friends, and now it is an accepted term for the following setup. I have observed some people on the net arguing about gravity vs. pressure vs. whatever. If you have comments like this as a result of this description, I refer you to: alt.engineering.geeks. The type of argument I have observed would have been halted a long time ago by declaring a "TECH TIME OUT !!" at our school. Take a hit man. I feel better now having said all that, so... on with the important stuff... GRAVITY BONG OPERATION: STEP 1: Place the bottomless bottle into a water source such as a bucket of water, sink, bathtub, larger bottle, fishtank (just kidding), etc...When the bottle rests on the bottom, the mouth piece should be above the water level enough to grip the bottle. I'm not sure if warm or cold water is best, or even if it makes much difference seeing as the smoke is not bubbled through it. STEP 2: Pack the bowl and place it on the mouth of the bottle. STEP 3: SLOWLY!! draw the bottle out of the water, while lighting the bowl. The herb should really burn and the smoke will look intimidating. Stop when: a)the herb is all ash (preferable), or b)when the bottom of the bottle is still an inch or so below the water level in the bucket. Begin preparing yourself for a huge hit. STEP 4: CAREFULLY remove the bowl without letting the bottle move downward (up a little is o.k., but don't lwt the bottom come out of the water), exhale deeply, and place your mouth over the opening. Inhale quickly and completely, allowing your head to move downward. Try not to drink any bong water as this kind of sucks! (although its like learning to swim, it's bound to happen a little).

Metaphysics & Epistemology Paper Essay

G. E. Moore’s main contributions to philosophy were in the areas of metaphysics, epistemology, ethics, and philosophical methodology. In epistemology, Moore is remembered as a stalwart defender of commonsense realism. Rejecting skepticism on the one hand, and, on the other, metaphysical theories that would invalidate the commonsense beliefs of â€Å"ordinary people† (non-philosophers), Moore articulated three different versions of a commonsense- realist epistemology over the course of his career. According to data I researched Moore’s epistemological interest also motivated much of his metaphysical work, which to a large extent was focused on the ontology of cognition. In this regard, Moore was an important voice in the discussion of sense-data that dominated Anglo- American epistemology in the early twentieth century. In ethics, Moore is famous for driving home the difference between moral and non-moral properties, which he cashed-out in terms of the non-natural and the natural. Moore’s classification of the moral as non-natural was to be one of the hinges upon which moral philosophy in the Anglo- American academy turned until roughly 1960. Moore’s approach to philosophizing involved focusing on narrow problems and avoiding grand synthesis. His method was to scrutinize the meanings of the key terms in which philosophers expressed themselves while maintaining an implicit commitment to the ideals of clarity, rigor, and argumentation. This aspect of his philosophical style was sufficiently novel and conspicuous that many saw it as an innovation in philosophical methodology. Moore is widely acknowledged as a founder of analytic philosophy, the kind of philosophy that has dominated the academy in Britain and the United States since roughly the 1930s. Moore also had a significant influence outside the academic philosophy, through his contacts in the Cambridge Apostles and the Bloomsbury group. In both academic spheres, Moore’s influence was due in no small part to his exceptional personality and moral character. One of the most important parts of Moore’s philosophical development was his break from the idealism that dominated British philosophy (as represented in the works of his former teachers F. H. Bradley and John McTaggart), and his defense of what he regarded as a â€Å"common sense† form of realism. In his 1925 essay â€Å"A Defense of Common Sense†, he argued against idealism and skepticism toward the external world on the grounds that they could not give reasons to accept their metaphysical premises that were more plausible than the reasons we have to accept the common sense claims about our knowledge of the world that skeptics and idealists must deny. He famously put the point into dramatic relief with his 1939 essay â€Å"Proof of an External World†, in which he gave a common sense argument against skepticism by raising his right hand and saying â€Å"Here is one hand,† and then raising his left and saying â€Å"And here is another,† then concluding that there are at least two external objects in the world, and therefore that he knows (by this argument) that an external world exists. Not surprisingly, not everyone inclined to skeptical doubts found Moore’s method of argument entirely convincing; Moore, however, defends his argument on the grounds that skeptical arguments seem invariably to require an appeal to â€Å"philosophical intuitions† that we have considerably less reason to accept than we have for the common sense claims that they supposedly refute.

Social Media and Network Technology

Colleges will need to embrace these new communities in order to keep up with recruitment of the younger generations, student to student interaction, student to professor interaction. Backbone and Linked are some of the internet communities that we will need to embrace to encourage our recruitment and student interaction. Backbone has been around since 2004 and is still growing in popularity. Backbone gives you the availability to send an instant message, an email, post discussions, provide media, and provide detail information.Colleges that have a Backbone page and interact with Backbone has the ability to recruit sophomores and Juniors in high schools not only in the surrounding areas but relied. This ability provides an advantage to have a more diverse student body. For young college students Backbone is a mean they utilize to communicate with other students about the activities going on in the campus. They also use this communication tool to converse about class assignments, organ ization functions, sports, and daily activities.Students who do not live on campus, Backbone allows them to still experience college life and the inclusion of student activities. College professors can also utilize this communication tool to correspond and interact with al students, including students who participate at satellite campuses. The surrounding community will also have the availability to interact with the students because they will be able to show the students the history of the area, and support the college with financial scholarships and the sports arenas.Most of the surrounding community makes up the professors, educators, the educator families and friends. Professors will have the accessibility to be active not only with the students but with the students families as well. As a parent of a college student, I enjoy being able to see what the students are doing, what classes are troublesome, the activities the students are participating in, and when parents can interac t with the student at school.The disadvantages of Backbone include accessibility, lack of personable interaction, lack of social interaction, non-clarifying answers, misunderstandings of context of messages and pictures, invasion of privacy, and possible compromise of security information. Yet, these disadvantages can be kept down to a minimum by the college handbook and the student conduct codes by the dents themselves. Most college's network security will keep secure information safe from any breaches or hacking. Linked will be very beneficial for our graduating students, faculty and local business.This social network will allow for the local and national business to see the types of students we are producing in the workforce. Linked will allow the students to make contacts with others in the corporate field of their choice and possibly encourage the company to reach an agreement with the college on training of their current staff. Our faculty will be able o utilize this social ne twork by seeing what the other colleges are teaching and producing in the coming work force and learn what skills the companies are looking for, and provide those skills to our students.The only down side to Linked will be headhunters from other colleges recruiting our faculty to come and work for them. But we can counter offer our faculty, pay retainer fees, and sign binding contracts with the faculty to keep them from leaving our facility. We will be using the waterfall model for the implementation of a Backbone page and Linked page. The system velveteen life cycle for this process we will need to make sure that all students will have access to the college Wi-If on campus, which we currently have in place all over the campus.Our second phase will include making sure that students and faculty will have accessibility to a computer, which currently we already have in place in the library and common areas. Our third phase of the process will require the college to set up a Backbone an d Linked account and have our IT department to maintain the accounts. Fourth phase of the process will require the college to get the rod out to the students about both pages on the internet and require all of our faculty to friend us on each site.The final phase will be having our IT department to hire someone to maintain both pages for content on the page, the context of the messages on the page and be a monitor for any violation of student conduct codes. The only disadvantage for using these websites, we will not be able to modify the systems. The advantages outweigh the disadvantage immensely because startup cost will be at a bare minimum, and we will still be able to get an idea of how many of our dents are using to communicate with one another by the amount of friend request we receive and the amount of conversation context on the page.

Art Paper Georgia OKeefe Essays

Art Paper Georgia OKeefe Essays Art Paper Georgia OKeefe Essay Art Paper Georgia OKeefe Essay Georgia O’Keeffe Georgia Totti O’Keeffe was an American artist born in 1887 and died in 1986. She has been a major figure in American art since 1920 and is chiefly known for paintings of abstraction and flowers, rocks, shells, and landscapes. She attended schools such as, School of the Art Institute of Chicago, and Art Students League in New York City. She did a lot of work and studying with watercolors. In the fall of 1908, Georgia became discouraged with her work and became an elementary art teacher for awhile. After leaving teaching, she met many American modernists who eventually inspired her to start working in primarily in oil. In the mid ‘20s she began painting large scale nature themed paintings. Her work was first exhibited in 1916 at the 291 Gallery of Alfred Stieglitz, whom she married in 1924. She lived much of her life in New Mexico which influenced much of her work as she painted numerous southwest themed paintings of bleached bones, rolling hills, cow’s skulls and desert blooms. She is nationally represented in some major museums. Her most personal paintings were said to be her flower paintings. She used a close-up photographic technique. One of her most representative and best-known paintings is Red Poppy which can be found in the Metropolitan Museum of art. Here she depicts a single flower accurately painted with a blast of redness and shagged petals. This painting is of course an enlarged version of a real life Red Poppy. She was inspired by the photographs of Paul Strand and Edward Weston.

Types of Cardiac Arrhythmia Resulting From Centrifugal Acceleration

Types of Cardiac Arrhythmia Resulting From Centrifugal Acceleration Abstract Cardiac arrhythmia is one of the many health conditions that form the basis of aviation medicine. The absence of adequate information around the condition necessitates studies to that effect. The current paper sought to determine the types of cardiac arrhythmia that result from aviation related movement.Advertising We will write a custom research paper sample on Types of Cardiac Arrhythmia Resulting From Centrifugal Acceleration specifically for you for only $16.05 $11/page Learn More The study relied on findings made in centrifugal training experiments, where subjects are usually placed in a human centrifuge. The objective was to expose the subjects to +Gz forces, which are similar to the ones in a military jet or a commercial flight. During such exercises, the tolerance level of the subjects was determined relative to the G-forces. It was found that sinus arrhythmia, premature atrial contraction, premature ventricle contraction, and atrial fibrill ation are the common cardiac arrhythmias during such exercises. Introduction Aviation Medicine An Overview There are certain health-related problems that are unique to the aeronautical and aviation industry.[1] Rayman points out that aviation medicine can also be referred to as flight or aerospace therapy.[1] The idea behind this kind of healthcare is the need for a medicinal approach in tackling the wellbeing of people in aerospace industries. Pilots and astronauts are good examples of individuals who are covered by aviation medicine. The principle behind this field is the fact that the patients find themselves physiologically affected by aviation-related factors, such as gravity. Advancement in the aerospace and aviation sectors imply that most of the aforementioned factors will increasingly affect the persons in the industry. Hanada, Hisada, and Koichiro affirm that progress is inevitable in the aviation industry.[2] An example is the case of air force pilots. The need to develop faster and effective jets means that the aerodynamic factors will be modified. Consequently, the pilots end up being affected by some of these forces. The advancements made in aviation medicine rely on its relevance to the world of aerospace. Whinnery indicates this importance by outlining the fact that the United States Air Force (herein referred to as USAF) has a School of Aerospace Medicine.[3] Such institutions justify the reasoning that research in aviation medicine is important. In a study to determine the state of affairs in Singapore in relation to this field, Gan, Low and Singh focus on the military and commercial flight areas.[4] In these fields, there is constant development of new and state-of-the-art machinery. However, as aforementioned, the same comes with consequences like increased arrhythmia.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Technological in novations in medicine are required in such fields as aviation physiology and performance maximization.[4] Other areas in which advancement is required include the selection of medical standards and protection of aircrew from communicable diseases, which may arise during a flight. However, for the purposes of this paper, discussions will revolve around the physiology aspect of aviation medicine. G-Forces in air planes Airplanes are constructed in such a manner that they respond to the laws of aerodynamics.[1] The operation of these laws relies on gravity and how to overcome it. Whinnery brings out the understanding that gravity, as a force, is observed as acceleration.[2] The implication is that there is motion involved. Going by the arguments made in Newton’s laws of motion, it is evident that gravity is characterized by several forces. The study restricts itself to the forces exerted on an aircraft due to gravity, which is referred to as ‘g-force’. According to Gan et al.,[4] g-forces are considered as accelerations, as previously indicated. As a result, one can determine these forces on the basis of their respective weights. By virtue of the acceleration nature of gravity, the g-forces appear to multiply the weights of a given mass. In the context of an airplane, these factors tend to reproduce the weight of the unit mass of the persons in the jet. To appreciate how a pilot will experience this multiplier effect, one ought to obtain the sum of the non-gravitational forces acting on them. The aforementioned non-gravitational forces are considered as the proper accelerations.[1] Their effects include stress and strain on persons in an aircraft. In their study, Whinnery[3] makes the claim that high amounts of g-forces are destructive to the aircraft and to the people. Effects of g-forces on human anatomy G-forces cause strain and stress on the bodies in an aircraft. In line with this, the elements have a physiological effect on human bodies. [1] Hanada et al.[2] affirm this hypothesis in their study on the effects of g-forces on military pilots. Most of the components of the human anatomy have mass. As such, the effects of stress and strain on them vary. Hanada et al.[2] indicate cerebral perfusion as a major impact of these forces. In such cases, the patients tend to suffer from a condition known as G-induced loss of consciousness (herein referred to as G-LOC). Such conditions are common among military pilots during the maneuvers displayed by the fighter jets. Arrhythmias is another common phenomenon resulting from the g-forces, especially in instances where flight crew are taken through centrifuge training.[4] In such cases, the pilots are subjected to the same conditions as those of a plane in the air. Consequently, the developments tend to alter the rhythmic patterns of an individual’s heartbeat. The effects of g-forces are so serious on the human anatomy to the extent that Hanada et al.[2] propose the presen ce of specialists during centrifuge training.Advertising We will write a custom research paper sample on Types of Cardiac Arrhythmia Resulting From Centrifugal Acceleration specifically for you for only $16.05 $11/page Learn More Effects of G-Forces on the Heart General effects An analysis of g-forces makes it apparent that human anatomy is severely affected by stress and strain, as illustrated in the previous section. Advances in aerospace technology imply that human body will continue to be subjected to such forces to determine its tolerance.[1] For the purposes of this study, it is important to understand the effects of g-forces on the heart as an organ in human anatomy. Cardiac arrhythmia The functioning of the heart is largely attributed to its electrical properties.[1] The stresses and strains brought about by the g-forces tend to affect the organ’s electrical attributes. As a result, the heart beat is altered. Conditions of this nature are wha t are referred to as cardiac arrhythmia. The condition is not age or gender specific. Whinnery[3] points out that the condition if often not fatal. However, studies illustrate that cardiac arrest is associated with arrhythmia.[2] Cardiac arrhythmia can occur in one of the compartments of the heart.[1] The same explains why there are different types of the said condition. Rayman[1] points out the existence of four types of cardiac arrhythmia. The first is supraventricular arrhythmia, which is characterized by a fast heart rate.[1] Secondly, there is bradyyarrhytmias. The condition arises when the heart beat is extremely low. In such cases, the blood hardly reaches the brain. The third type is ventricular arrhythmias. The occurence is associated with the lower chambers of the heart.[1] Finally, there is premature beats. It is a type of arrhythmia associated with the upper atria of the heart. The ‘premature beats’ are an indication of a mild form of arrhythmia, whose sympt oms are not easily noticeable.[5] Cardiac arrhythmia in aviation medicine The aviation industry is a sensitive area, which involves out of space explorations and normal flights. The machines involved are quite complex. The sophistication requires the complete application of the pilot’s cognitive abilities. Within the broad spectrum of aviation medicine, cardiac arrhythmia falls under the physiological effects. The heart plays an important role in human anatomy.[6] As such, studies have been conducted to illustrate how best to overcome the condition. Factors influencing g-force provoked arrhythmia During centrifugal training, the participants are subjected to +Gz forces. The procedure leads to stress that affects human anatomical functions. It is evident that cardiac arrhythmia results from the effects of the G-force on the heart. The rhythms are distorted from their normal patterns.[7] It is important to appreciate the factors that influence the occurrence of arrhythmia due t o the G-forces. Over the years, aviation medicine has relied on centrifugal training to obtain information about cardiac arrhythmia. Such information includes the various types of the condition and their influencing factors.[7] Experiments carried out to determine this rely on the use of human centrifuges, which are found in special units. The most common areas where such apparitions are found include special aviation medical departments in military wings.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More One of the factors that influence cardiac arrhythmia during centrifugal training is the magnitude of the +Gz. Ewalina and Lech[7] proved this in a study in which they sought to determine hemodynamic changes resulting from centrifugal acceleration and the corresponding cardiovascular responses. The study reveals that an acceleration of 1Gz is responsible of acute hemodynamic changes. The same magnitude of acceleration was found to be an activator of cardiovascular responses, arrhythmia being one of them.[7] Anti-G straining maneuvers (herein referred to as AGSM) are other factors that influence g-force-provoked arrhythmia. Ewalina and Lech[7] point out that the same has a direct effect on the nervous system, which impacts on the heart’s electrical properties. Such measures are seen as an attempt to reduce the effects of g-forces. They limit the impacts of +Gz on the electrical characteristics of the heart. Other factors include the health status of the subject and the duration of exposure. Latent cardiac medical histories give mixed results. Exposure durations increase the chances of cardiac arrhythmia, which further aggravates the severity of the conditions. Materials and Methods Introduction The current study is hinged on the hypothesis that centrifugal acceleration results in cardiac arrhythmia.[1] The research relies on a series of peer reviewed articles, which provide a detailed discussion of the topic. More importantly, the articles relied on address the issue of g-forces and their effects on human subjects. They illustrate the various types of arrhythmia and their relationship with g-forces. +G Acceleration and Corresponding Detection of Cardiovascular Responses In an experiment, Vettes, Viellefond, and Auffret[6] determined that g-forces have a corresponding cardiovascular response from the heart. The researchers deduced this by carrying out detailed studies on the issue. The subjects used were all male and individually volunteered for the exerci se. The studies were carried out in a laboratory in France. The location, known as the Aerospace Medicine Laboratory of the Flight and Test Center, contained the equipment necessary for this research.[6] The male volunteers had an average age of 37 years.[6] After the preliminary medical check-ups were concluded, all the subjects were found to be medically fit for exposure to g-forces. Preliminary tests carried out at the Central Medical Examination Centre for Flying Personnel, which is situated in Paris.[6] Thirteen of the participants did not have prior exposure to centrifugal acceleration. According to Vettes et al.,[6] +Gz g-forces were required for the study. The said forces are attained when a human centrifuge is rotated longitudinally. The specific centrifuge used in this research had a vertical rotating axis, whose arm was six meters.[6] A gondola is attached at the arm’s extreme end. Human subjects occupy this space. The centrifugal acceleration in this regard is obt ained by means of a perpendicular rotation of the arm relative to the gondola. During this rotation, the apparatus moves along the axis, exposing the subject to the +Gz forces arising from acceleration. To ascertain the responses, certain cardiac parameters are taken into account.[6] Such parameters as the subjects’ rate of heartbeat and arterial pressure were are determined. The study by Vettes et al.[6] required the stoke volume and the subjects’ visual fields to be recorded as part of the preliminary medical analysis. Each of the electrocardiographs was analyzed by means of a special electrode. The electrodes are placed on 3 locations on the subjects’ body. The first two are placed on each of the axillae, while the third is placed on the lumbar spine. In so doing, the researchers minimize the noise that would otherwise be present due to the muscle-related contractions. The arterial pressure on the other hand is obtained by means of a syphgamanomter.[6] The sa id machine is normally inflated by means of an electrovalve that is remotely controlled. To obtain the actual pressure in a subject, a curve on the machine is needed.[6] In addition, there is a microphone placed at a strategic point to detect specific noises. In the study, the researchers were able to record their patients’ rates of heartbeat using a phonocardiograph. However, there are exceptions where the heart rate is determined by taking measurements of 10 systoles from the machine. Safety Criterion The study by Hanada et al.[2] sought to develop a safety criterion for centrifugal training. The study relied on pilots from the Japanese Air Self-Defense forces. Each of the subjects was conversant with F-4, F-15 and F-2 fighter jets.[2] Such familiarity was a requirement to be part of the study. It was meant to ensure that the subjects were all familiar with increased G-forces due to the aircrafts’ high rates of acceleration. As expected, there was a preliminary medic al examination carried out on each of the participants.[7] In addition, the subjects were taken through a pre-determined duration of centrifugal acceleration to obtain specified results. The study created several profiles to analyze the effects of different +Gz forces. The data analysis phase was characterized by anonymity. The names of the pilots were not included in the profiles. G-Force Tolerance In their study, Blue et al.[5] examined levels of tolerance associated with g-forces during centrifugal training. The study revolved around subjects with an interest in spaceflight. The participants were part of Virgin Galactica crew and would- be passengers. An equipment referred to as a ‘Space Training Simulator’ was used in the study. The machine operates like a human centrifuge. Prior to the experiment, a medical examination was carried out. Afterwards, the subjects were taken through an anti-G straining procedure. There was a descriptive representation of the data colle cted in the study. Cardiac Arrhythmias in Flight and Centrifuge Simulations In their article, Ewalina and Lech[7] argue that centrifuge acceleration has an effect on cardiac arrhythmia. Consequently, their study analyzed the two scenarios in which such acceleration is achieved. They examined the rhythm balances when the subjects are in centrifuge training and in actual flight. Ewalina and Lech[7] point out that the two instances have similarities and differences. Ultimately, the research sheds more light on cardiac arrhythmia resulting from centrifugal acceleration. In the study, Ewalina and Lech[7] relied on 20 experienced pilots and 20 students. The student pilots were selected from a group of 3rd and 4th year cadets in the Polish Air Force Officers’ College. According to Ewalina and Lech,[7] the average age of the experienced pilots was 35.3 years. There was an allowance of 4.9 years in the positive and negative extremes. The average height was 176.6 cm, while body mass wa s 79.3kg.[7] The average flying hours of the experienced pilots was estimated at 2620. The trainee pilots, on the other hand, had an average age of 21.9 years and median height of 178.2 cm.[7] Their mean body mass was 78.7kg. They had an average of 252 flight hours on their records.[7] One of the requirements for participation in the experiment was that none of the pilots should take any form of medication. Ethical issues were also taken into consideration, where the participants were required to submit a written consent. The approval to conduct the study was granted by an ethics committee constituted by the ‘Polish Air Forces Institute of Aviation Medicine.’[7] The study required the subjects from the two groups to carry out flight protocols in pairs, where one acted as a pilot, and the other as a passenger.[7] Each of the subjects was required to make 2 flights. In the first flight, the subject was required to act as a ‘pilot’ (herein referred to as AF). The second flight demanded that they act as a passenger (herein referred to as PF). According to Ewalina and Lech,[7] the participants were required to take a break in-between the flight schedules. The study gave an allowance of 1 hour as the duration of time that each pilot should take before taking part in the next flight. To attain consistent results, all the subjects made use of the same TS-11 ISKRA Jet.[7] Once all the pilots had made their required flights, the researchers took a break of two days. During the break, the subjects underwent human centrifuge tests. It is important to note that the subjects did not wear G-suits during the study. The omission was meant to allow the +Gz effects to be conclusively examined. The forces were generated from the maneuvers carried out in the flight program. They ranged from 0.57 G.s-1 to 4Gz when the maneuver involved three successive turns.[7] With regards to the split S maneuver, the acceleration was recorded between 1.7G. s-1 and 5.6 G z.7 The ‘two-successive loop’ maneuver was characterized by an acceleration of 1.4G.s-1 to 5.0Gz. The other maneuvers carried out were the immelman and the one turn. The former had an acceleration of 5.6Gz, while the latter gave results identical to all the other maneuvers.[7] The results from the flight protocols were recorded separately. As aforementioned, the study carried out a centrifuge test. The same was realized using a centrifuge with a radius of 10 meters.[7] The equipment was provided by the Acceleration Tolerance Laboratory, which is situated within the Institute of Aviation Medicine. The latter is a department of the Polish Military. At the resting level, the acceleration was +1.4Gz. Thereafter, it was increased by 1G.s-1 to a maximum of 7Gz. When the human centrifuge was involved, the accelerations were set at levels similar to the aerobatic maneuvers.[7] +GZ and the Electrocardiographic Response Whinnery[3] sought to establish that the g-forces experience d during centrifuge training have an effect on an individual’s electrocardiographic (herein referred to as ECG) response system. The study involved a total of 59 subjects. According to Whinnery,[3] the research relied on the responses of the flight surgeons that developed the acceleration profiles of the subjects. The participants were drawn from the United States Air Force and the United States Navy.[3] The two training profiles developed for the study included the gradual and the rapid onsets. According to Whinnery,[3] observation of the subjects was carried out based on their respective ECG dysrhythmias. The first profile was developed when the participants were allowed to put on a standard anti-g suit. Whinnery[3] points out that the suit was not inflated. There various reasons why inflation was omitted. The major objective was to ensure that the subjects were relaxed and that their loss of peripheral vision was gradual. The maximum limit of +Gz was estimated at +9Gz. It is important to note that the tolerance levels during the centrifuge training were recorded from 2 extremes. There was the relaxed and the straining levels of tolerance.[3] In both cases, the aim was to obtain the proficiency of the anti-g element in the experiment.[3] The researchers analyzed the various symptoms exhibited by the subjects. To achieve this, the results were computed in terms of the average, standard deviation, minimum, and maximum.[3] Whinnery[3] used the ages of the subjects to estimate the results. Of particular interest was the comparison between the ectopy occurrences among the subjects. The incidences were analyzed by means of a correlated proportions test referred to as McNemar.[3] An elaborate outline of the results is discussed in the subsequent sections of this paper. The objective, as already mentioned, is to build on the hypothesis of the current study. The discussions will involve results from studies similar to the ones referred to in this section. Resu lts Introduction to the Results From the materials and methods discussed in the previous sections, it is apparent that there is enough evidence to support the hypothesis made in this paper. The evidence suggests that cardiac arrhythmia is caused by g-forces that result from centrifugal acceleration.[5] The results of previous studies conducted in this field highlight the various types of arrhythmias and the effect of centrifugal acceleration on the rate of heartbeat. In addition, the findings made illustrate the various cardiovascular parameters related to arrhythmia. In line with this, analysis of this condition in relation to centrifuge is outlined in this section. Types of Arrhythmias As aforementioned, there are multiple types of arrhythmias. Each of them has unique characteristics that set it apart from the others.[6] In a study to determine the safety measures needed to be put in place during g-flight training, Hanada et al.[2] found out different types of this condition. The findings are illustrated in Table 2 below: Table 1: Types of cardiac arrhythmia Number of Participants Percentage of Occurrence (%) Type of Arrhythmia 114 58.5 Single PVC 95 48.7 Sinus Arrhythmia 63 32.3 Single PAC 19 9.7 Paired PVC 5 2.6 Ventricular tachycardia 3 1.5 Paroxysmal supraventricular tachycardia 3 1.5 Repeated PAC 1 0.5 Paroxysmal Atrial Fibrillation 1 0.5 Ventricular bigeminy or trigeminy Adapted from: Hanada et al.[2] The study by Hanada et al.[2] reveals 9 types of cardiac arrhythmia associated with centrifuge acceleration. The figures listed in table 1 above were obtained from a research conducted by the Japan Air Self-Defense Force (herein referred to as JASDF). The most common condition recorded during the study was single premature ventricular contraction (herein referred to as PVC) at 58.5 percent. The occurrence of both Paroxysmal Atrial Fibrillation and ventricular bigemny or trigemny was recorded at 0.5% in one of the participants, maki ng it the least common of all. Centrifugal Acceleration and its Effects on the Rate of Heartbeat As previously mentioned, centrifugal acceleration has an effect on human anatomy. The effects of this phenomenon on human body vary between different organs. Studies reveal that centrifugal acceleration gives rise to g-forces. As such, it follows that their effects on the heart touches on its rhythms, leading to cardiac arrhythmia.[7] In their study, Whinnery[3] affirms that g-forces affect an individual’s heart rate. Table 2 below illustrates results of the study by Whinnery.[3] The effects of the forces on the human heart are documented in the table. Table 2: G-force exposure and corresponding heart beat rates Lown grade Ectopy Definition Subjects with highest Lown grade 0 Absence of ventricular premature depolarizations 12 1 5 PVC 31 2 5 PVC 3 3 Multiform PVC 1 4A Paired PVC 8 Source: Whinnery[3] In this research, Whinnery[3] relied on one type of cardiac arrhyt hmia. As illustrated in table 2 above, the study examined the rates of heartbeat in relation to the effects of exposure to +Gz forces. The analysis is based on a Lown grading system. Such a system is used to classify heartbeats with regards to cardiac arrhythmia.[8] Whinnery[3] selected a cluster from the known classifications, as shown in table 2. The experiment analyzed results from a total of 59 participants. It was found that +Gz forces affected an average of 11 subjects. The same is inferred from the data in table 2. Cardiovascular Parameters Studies aimed at examining the effects of centrifugal acceleration rely on specified cardiovascular parameters. Vettes et al.[6] posit that the +Gz forces arising from centrifugal acceleration rely on such factors. They determine such responses as cardiac arrhythmia. The said parameters include an electrogram and the visual field of the subject. In addition, the heart rate and humeral arterial pressure of the participants are factored in t he study. They make up the cardiovascular parameters recorded during such experiments.[6] Vettes et al.[6] point out that increased exposure to g-forces was followed by a corresponding increase in the rate of the individual’s heart beats. The results from their experiments illustrated that peripheral loss of vision among the subjects was an indicator of the effects of the +Gz forces. The latter is regarded as a key symptom indicating the onset of cardiac arrhythmia. The study by Vettes et al.[6] revealed that the highest recorded heart beat per minute was 113, whereas the lowest was 84. In terms of pressure, Vettes et al.[6] illustrated that increased exposure to these forces (up to levels of +3 Gz) resulted in a corresponding rise in arterial pressure. To this effect, blood pressure is treated as an essential parameter in understanding cardiac arrhythmia. The same explains the effects of exposure to g-forces. The scenario is similar to electrocardiographic recordings, which vary depending on the accelerations. In their study, Vettes et al.[6] point out that increased heart pressure was the cause of arrhythmia. The reason is that the pressure led to atrio-ventricular dissociation. Effects of Centrifuge Training on the Heart The major focus of this study is centrifugal acceleration and its effects on human anatomy.[9] Aviation regulations require pilots (and in some cases passengers) to undergo some level of centrifugal training. Such trainings simulate the acceleration likely to be experienced in fast moving aircrafts. An example of such instances involves commercial space-crafts.[5] The high acceleration associated with such crafts requires some training to acquaint the persons with the g-forces. Blue et al.[5] carried out a similar study in which occupants of a spaceflight were subjected to centrifugal-stimulated sub-orbital flight. The objective was to create conditions similar to those in a fast moving aircraft. The participants in the study by Blue et al.[5] were all healthy. The simulation was expected to provide information on how g-forces affect the heart. It was also expected to shed light on the influence of the forces on the occurrence of cardiac arrhythmia. Their study used a total of 81 participants[5]. The research by Blue et al.[5] required healthy individuals. As a result, all the participants were subjected to medical screening.[6] Consequently, the initial number was reduced to 77 subjects. Out of this, 65 were men, while 12 were women. Another batch of 21 participants was subjected to cardiac examinations to check for any latent complications. The medical examinations revealed that 16 had histories of hypertension, while 5 had diabetes. Another 5 had undergone a coronary heart bypass. In addition, 17 participants had a history of hyperlipidemia. Prior to the simulation, there were 2 individuals who were found to have severe cases of peripheral vascular disease. The objective of these tests was to obtain exact re sults from the simulations. The aim was to ensure that the findings made were due to g-forces from centrifugal acceleration and not from latent conditions. The participants with medical histories had little complaints from the centrifugal acceleration in comparison to those without backgrounds of medical conditions. However, both sets of participants complained of nausea. The same is common in cases where subjects are exposed to high centrifugal acceleration. Another effect of this development was greyout. To this end, participants complained of incidences of mild greyout. Interestingly, none of the participants experienced any form of G-LOC. There were, however, incidences where the participants would perform head movements with the sole objective of self-inducing sensations similar to coriolis. Discussion Overview From the various experiments highlighted in the current study, it appears that cardiac arrhythmia is caused by g-forces associated with aerodynamics.[10] The various stu dies made reference to centrifugal acceleration. It is not possible to obtain results from the specific aircrafts that the researchers used to generate centrifugal acceleration. As a result, most studies depend on simulations of conditions found in an aircraft.[11] During such instances, the subjects are rotated at speeds that are almost equivalent to those in an aircraft The objective of such simulations is to expose the subjects to g-forces from acceleration.[12] The specific elements observed are the +Gz forces. The designation ‘z’ implies that on a 3 dimensional plane, the said forces act on the z axis. Their effects on the subject are longitudinal. In addition, they are the most common forces that affect the rhythm of an individual’s heart when in flight.[13] The different levels of exposure to g-forces are a contributing factor to the occurrence of the various types of cardiac arrhythmia. The study by Hanada et al.[2] highlighted three types of arrhythmia c ommon among pilots, especially in military jets. The three were identified as PAC, PVC, and sinus arrhythmias. According to Hanada et al.,[2] the three occurred due to the variant levels of exposure to +Gz. For instance, sinus arrhythmia occurs in instances where subjects are exposed to high g-forces. In such cases, the resulting levels of stress are high. The same has an effect on the heart rate. It distorts the rhythm of these rates once the subject comes to rest. It is noted that PVC and PAC are the most common types of arrhythmia that result from interactions with high-G training.[14] Hanada et al.[2] addressed this issue by pointing out that the two are common in normal day-to-day exercises. The researchers found it prudent to do away with centrifuge in cases where subjects exhibited PAC and PVC.[2] The argument is strengthened by the assumption that the two arrhythmias are a normal occurrence among subjects. The study by Hanada et al.[2] introduced the element of grading the r ate of heartbeat rhythms among subjects. The system is essential in determining the degree or severity with which arrhythmia exhibits itself.[15] In this grading system, arrhythmias that are recorded at a grade of three or higher are regarded as severe. It is noted that 10% of the subjects in the study by Hanada et al.[2] exhibited a paired condition of PVC. The researchers argue that the condition is a direct physiological response to the stress experienced during the centrifugal acceleration in training sessions. The Lown grading system for ectopy was developed against the backdrop of the need to characterize the different types of arrhythmia. The same explains why, in the study by Hanada et al.[2], PAC and PVC are graded according to the degree of exposure to +Gz. An example is in the case where there is paired PVC and PAC, while at the same time single cases of PAC and PVC are noted. In both cases, the Lown format becomes vital in highlighting the severity of the different types of arrhythmia. The Lown system is one of the advancements made in aviation medicine. It is used to determine the types of arrhythmias that are permissible in centrifugal training. An example is evident in the study by Hanada et al.[2], where the system is used to sanction centrifugal training in cases where subjects exhibit paired PVC. However, training sessions are terminated in cases where the arrhythmias go beyond a specific threshold.[2] In such cases, the severity of the condition is determined by such factors as proaxysmal atrial fibrillation. Hanada et al.[2] posit that there are certain tachycardiac arrhythmias that reduce tolerance to G-stress resulting from centrifugal acceleration. In such cases, the subjects exhibit PSVT and VT. Their study revealed that PVST is possibly a major cause of loss of consciousness during centrifugal training.[15] The findings made in the current study are best understood from the perspective of a detailed discussion of centrifugal accelerati on and its effects on the heart. In so doing, the researcher aims to prove that cardiac arrhythmia is a result of centrifugal acceleration. In this section, the specific types of this condition are analyzed in detail. Protocols for Centrifugal Acceleration The findings in this study reveal that centrifugal acceleration is an important component of aviation medicine.[16] The process creates an environment that is similar to that experienced in fast moving aircrafts like fighter jets. Such individuals as military pilots and astronauts are the most affected by the G-forces arising from the acceleration of high speed aircrafts. It follows that such individuals require some form of training to acquaint themselves with the strenuous conditions and to help them bear with the stresses brought about by the forces. Centrifugal training, as already indicated, is the process through which pilots and other crew members are subjected to controlled conditions of G-stress. During such sessions, avi ation medical personnel examine individual subjects’ tolerance to G-forces.[2] It is important to take the subjects through certain protocols. Such a move is necessary as it helps in the attainment of accurate results from the exposure to the said forces. Several studies are used to elaborate the importance of these protocols as indicated in the ‘methods’ section of this paper. The first and most important protocol to follow in centrifugal training is preliminary medical check-ups.[1] The procedure is evident in the studies by Hanada et al.[2] and Whinnery[3], where the subjects are screened for heart related complications. The objective of such preliminary medical examinations is to ensure the effects of G-stress exposure are not confused with the symptoms of latent medical conditions. The second protocol during centrifugal studies is the exposure levels.[3] During the training exercises, the subjects must be exposed to varying levels of +Gz so that a proper com parison can be arrived at. For instance, Whinnery and Hickman[8] sought to study mitrial prolapsed and thus relied on centrifugal acceleration. Their subjects were exposed to stress levels of 1G.15s-1 which were gradually increased. There was also another exposure referred to as the rapid onset exposure in which the subjects experienced g-forces of 1 G.s-1. The initial tolerance level is essential in evaluating cardiovascular reflexes.[8] On the other hand the second tolerance level are useful in determining the subjects’ tolerance in terms of the hydraulics. During these exposure levels, in centrifugal training, it is expected that the subjects end up experiencing total loss of their peripheral sight. The aforementioned protocols are key in ensuring that the results are obtained as expected.[8] Arrhythmia Resulting from Centrifugal Training Overview From the findings in this paper, it is apparent that the rhythm of the heart is distorted by the G-stresses during centrifugal training.[17] As previously mentioned, centrifugal training involves rotation of subjects in a contraption referred to as a human centrifuge. The objective is to expose the participants in such exercises to +Gz forces.[3] Consequently, the individuals in such studies are observed to determine how the G-forces affect their human anatomy, of which the heart is a vital component. The contents of the articles referred to in the current paper reveal that there are 4 major types of arrhythmias that result from centrifugal acceleration.[4] The four include sinus arrhythmia, premature arterial contraction, arterial fibrillation, and premature ventricular contraction.[3] In order to categorize each of the mentioned arrhythmias, the author of the current study made observations depending on the levels of +Gz exposure. A detailed discussion is provided in this section. Sinus arrhythmia According to Rayman,[1] the heart has a specific rhythm to which it beats. Consequently, any external force l ike g-stress tends to distort the normal pattern of this organ, resulting in what is now known as cardiac arrhythmia. From the articles reviewed in this study, subjects in centrifugal training experiments were found to exhibit sinus arrhythmia among other complications known in aviation medicine.[9] The study by Hanada et al.[2] revealed that this complication is common during centrifugal training, where the subject’s heart rate normalizes immediately after a rapid heart-beat rhythm. Interestingly, there were subjects who exhibited this particular kind of arrhythmia prior to centrifuge acceleration and the subsequent exposure to the +Gz forces. As illustrated in table 2, the occurrence of the SA in the participants was recorded at 48%. It is important to appreciate that the high occurrence rate is not really due to the centrifugal acceleration. Hanada et al.[2] argue that the condition is a normal occurrence, especially among persons involved in physical training. Studies ill ustrate that the normal rate of a healthy adult lies between 60 to 100 beats every minute.[1] However, some studies indicate that the pattern varies between the genders. A normal female’s heart rate, for instance, is estimated to fall between 47 and 103 beats for every minute.[17] In men, the estimated rhythm is placed at the range of 43 to 102 beats per minute. Alterations in heart beat rhythm due to sinus arrhythmia are not fatal. There are cases where the condition cannot be detected. As such, members of a flying crew who are found to have the condition are not in danger. Premature arterial contraction (PAC) The human heart is fitted with a pace maker that has electrical characteristics.[1] as a result, when this part is exposed to external forces, there are distortions in its normal functioning. Centrifugal acceleration, as aforementioned, has an effect on the organ. The resultant +Gz forces give rise to G-stress. As mentioned earlier, these stressors tend to affect the n ormal workings of the human anatomy. The pacemaker is among the body parts affected. As a cardiac arrhythmia, premature arterial contraction is a phenomenon where the heart’s pacemaker emits signals before the ‘stipulated’ time.[18] The maker is located above the ventricles, meaning that these chambers respond to the distorted signals. As a result, the heart’s rhythm is altered by the ventricle’s ‘irregular’ response. An arrhythmia of this kind is usually common when an individual is stimulated either through exercises or as a result of such beverages as coffee. However, the same is also true when an individual undergoes centrifugal training.[2] In the study by Hanada et al.,[2] PAC exhibited itself in a number of the subjects used in the experiments. Despite the fact that the condition is not lethal, it can present itself in a manner that would require a discontinuation of the training. In such cases, it is considered as clinically sev ere. Hanada et al.[2] point out that repeated PAC is quite severe and advices intermittent discontinuation of centrifugal training among subjects who exhibit the condition. Premature ventricular contraction (PVC) The heart’s functions rely on the electrical impulses of the pacemaker.[19] In cases where +Gz forces are introduced into the human anatomy, the said impulses are interfered with. When such interferences occur, the functioning of some of the compartments of the heart is impeded, resulting in a distorted rhythm of heart beat. As an example of cardiac arrhythmia, PVC is characterized by the contraction of the heart’s ventricles before the expected electrical signal. The name ‘premature’ is sourced from this irregular contraction of the ventricles. The diagram below is an ECG representation of this condition: Graph 1: Premature ventricular beats Source: Vettes et al.[6] The study by Hanada et al.[2] points out that PVC can exhibit itself in differen t degrees. There is the occasional premature ventricular contraction, which is a mild version of the condition. Subjects who present the said condition are allowed to continue with centrifugal training owing to the fact that it is not harmful. The harmful case of PVC involves repeated PVC and Bigeminy, Trigeiny PVC. However, in spite of the fact that it is more harmful in comparison to occasional PVC, the latter case calls for the termination of centrifugal training after some time. A look at the study by Hanada et al.[2] reveals that 19 pilots exhibited the paired PVC condition. The number of subjects who presented the condition in subsequent training sessions kept on decreasing. The same indicates that despite being a common occurrence due to centrifugal training, PVC is only severe when a subject is exposed to High G-Stress over a long period of time without a break. A case in point is a pilot who travels in an aircraft at speeds that result in a stress of 5Gz.s-1 without taking a break. Such an individual is likely to experience a severe case of PVC, which might lead to cardiac arrest.[18] Artrial fibrillation Exposure to +Gz requires some form of tolerance from the persons participating in the centrifugal acceleration exercises.[19] Increased exposure and the resultant stresses affect the heart’s electrical functions. The atrial happens to be another region of the heart that is affected by the G-forces. According to Rayman,[1] the +Gz forces can increase the rate at which the pacemaker emits electrical impulses. When this happens, the ventricles contract in an irregular and erratic manner, leading to arterial fibrillation.[20] Whinnery[3] points out that exposure to G stress in such centrifugal exercises is characterized by atrial ectopy. As is the case with the other arrhythmias mentioned in this paper, this condition can be mild or severe depending on levels of exposure. For instance, Vettes et al.[6] suggest that the complication is regarded as normal when subjects are exposed to +2G for about five minutes. However, the researchers point out that the condition becomes severe in cases where the G-force is increased to +5G and the subjects exposed to the same for a period of more than five minute. Conclusion Vettes et al.[6] point out that centrifugal training, and by extension centrifugal acceleration, has a direct impact on cardiac arrhythmia. In the context of this study, centrifugal acceleration is regarded as an avenue of generating G-forces to create stress on human anatomy. Aviation medicine makes use of centrifugal training to effectively understand cardiac arrhythmia. In essence, this condition is caused by the distortion of the normal heart beat. Whinnery[3] introduced the element of human centrifuge in their study. The contraption is used in aviation medicine to conduct experiments on centrifugal acceleration. During such experiments, two main factors determine how G-forces give rise to cardiac arrhythmia. The two include the degree of +Gz and the duration of exposure. Intensity and duration are crucial elements in explaining the various types of arrhythmias. Hanada et al.[2] point out that centrifugal acceleration in centrifugal training exercises gives rise to 3 main types of arrhythmias. The analysis points out that sinus arrhythmia, premature atrial contraction, and premature ventricular contraction are the most common conditions. Atrial fibrillation is another type of arrhythmia associated with the exercises. Each of the conditions above is graded on their severity depending on the magnitude of +Gz. in addition, the duration in which the participants are exposed to the forces adds to the severity of the conditions. As such, it is important to pay attention to the degree of these conditions among individuals taking part in centrifugal training. The aim is to avert cases of cardiac arrest. Such occurrences are fatal, especially when the subjects are exposed to real time flight conditions. References Rayman BR. Clinical aviation medicine.

How John McAdam Changed Roads Forever

How John McAdam Changed Roads Forever John Loudon McAdam was a Scottish engineer who modernized the way we build roads. Early Life McAdam was born in Scotland in 1756 but moved  to New York in 1790 to make his fortune. Arriving at the dawn of the Revolutionary War, he began working in his uncle’s business and became a successful merchant and prize agent (in essence, a fence who takes a cut from selling off the spoils of war).   Returning to Scotland, he purchased his own estate and soon became involved in the maintenance and governance of Ayrshire, becoming a road trustee there. Builder of Roads At the time, roads were either dirt paths susceptible to rain and mud, or very expensive stone affairs that frequently broke down not long after whatever event precipitated their construction.   McAdam was convinced that massive stone slabs would not be needed to carry the weight of passing carriages, as long as the road was kept dry. McAdam came up with the idea of raising roadbeds to ensure adequate drainage. He then designed these roadbeds using broken stones laid in symmetrical, tight patterns and covered with small stones to create a hard surface. McAdam discovered that the best stone or gravel for road surfacing had to be broken or crushed, and then graded to a constant size of chippings. McAdams design, called MacAdam roads and then simply â€Å"macadam roads,† represented a revolutionary advancement in road construction at the time. The water-bound macadam roads were the forerunners of the tar- and bitumen-based binding that was to become tarmacadam. The word tarmacadam was shortened to the now-familiar name: tarmac. The first tarmac road to be laid was in Paris in 1854, a precursor to todays asphalt roads. By making roads both significantly cheaper and more durable, MacAdam triggered an explosion in municipal connective tissue, with roads sprawling out across the countryside. Fittingly for an inventor who made his fortune in the Revolutionary War- and whose life’s work united so many- one of the earliest macadam roads in America was used to bring together the negotiating parties for the surrender treaty at the end of the Civil War.  These reliable roads would be crucial in America once the automobile revolution began in the early 20th century.

Case study - Essay Example hains under the umbrella of Inditex are involved in various business industries such as manufacturing, textile, real estate, and finance among others (Ghemawat and Nueno 7). Despite being under the same umbrella of Inditex, each chain operates independently, a factor that has contributed to Zara’s massive success in comparison to the other chains. With an expansion strategy from the firm’s founder, Amancio Ortega Ganoa, Zara has been able to open new stores in the past years with the first opened in upmarket shopping street in La Coruna, in 1975, in Spain, Zara’s home base (7). Expansion has however, seen it go international with other store being opened beyond the Spanish boundaries from which it has been able to expand substantively especially in logistics and IT (9). Zara has been able to beat its competitors in the market by making customer preference their priority, enabling for the production of distinctive products that meet the customers’ needs. In a strategy named ‘vertical integration,’ Zara observes the current trends in the fashion industry and works towards production of products that are considered the next trend in the fashion industry. Ideally, this has been the greatest success orientation for Zara. In addition to expansive marketing, Inditex, as an umbrella organization through its supply chains including Zara, has established effective and able management team that run each of the chains with utmost objective in achieving success (6). This aspect has as well contributed immensely towards the overall success of Inditex and its chain units. Despite the success orientation that Inditex has been to experience in the past years, difficult times are looming in the new future for this firm considering that a majority of the stores under it are working on expansive strategies that would see them acquire new market bases. This could be disastrous to Inditex considering that each of the chains operates on an independent basis. Other than the

Ethical consumerism Coursework Example | Topics and Well Written Essays - 2000 words

Ethical consumerism - Coursework Example This report describes various meaning of consumerism and describes various approaches adopted by Cooperative group of companies in carrying out its social activities. The report concludes by providing the gap that exist the current study of consumerism. Ethical consumerism (also known as ethical purchasing, ethical consumption, ethical sourcing or ethical shopping) is a type of consumer activism that is based on dollar voting. This concept is practiced through positive buying where ethical products are given first priority. Ethical consumerism was first popularized by a UK magazine published in 1989 so as to produce rating tables which was inspired by criteria-based approach of the ethical investments movement. Ethical consumerism also means that several customers are willing to buy ethically sourced goods that are ethically made and distributed. On the other hand, an ethical consumer is someone who buys things that are ethically produced. Depending on the context used, ethical production means producing a product that is recycled, use of labor that is produced in facilities without using child labor and slavery, or producing food that is free range or organic raised. Therefore the whole idea of ethical consumerism movement is that you know what you are purchasing and that you buy products that are ethically produced since not knowing results to abuse and exploitation. Consumerism is used by other stakeholders as a tool for social change, basing on the theory that organizations make decisions basing on consumer demand. This idea is evidently limited by the massive power of large organizations which influence, if not create, consumer demand through branding and advertisement. Nevertheless, consumer power may be utilized to ensuring that companies are made accountable to the society; where common citizens in their consumer role can make companies to be accountable. Some authors (Ayglon 2009) regard consumerism as a tool for social change while others (Lang & Tahc

Sustainable Energy Resourses vs. Climate Change Essay

Sustainable Energy Resourses vs. Climate Change - Essay Example 3. Advantages and Disadvantages of Using Solar, Wind, Hydropower, and Geothermal Energy over Fossil Fuels Because of environment, health, long-term cost efficiency and other practical reasons, generating electricity out of the wind turbine, hydroelectric power plant, geothermal energy, and solar energy can be more advantageous as compared to the use of fossil fuels. When using either fossil fuels or biomass combustion, the Science Daily reported that approximately 20% of the energy produced is actually wasted as heat. Based on this context, fossil fuels and biomass are inefficient sources of electricity (â€Å"Shifting the world to 100 percent clean renewable energy as early as 2030†). Depending on the availability of renewable energy resources, the use of the wind turbine, hydroelectric power plant, geothermal energy, and solar energy system can provide us with more economic advantages since the overall supply of energy will be greater than our daily consumption needs ( "Shifting the world to 100 percent clean renewable energy as early as 2030†). Furthermore, the use of these renewable energy resources can provide us with long-term ready supply of energy without the possibility of causing serious damages to our health and environment. Among the available sources of renewable energy, the solar system is considered a very good source of electricity since the process of generating electricity from the sun can provide us with 30 times more than the total electricity that we actually need to run the entire U.S. economy (â€Å"Shifting the world to 100 percent clean renewable energy as early as 2030†). On the other hand, wind turbines are also considered as another powerful source of electricity since the energy generated from the wind... It can be derived from the report and the previous research conducted on the topic that a sustainable community is attainable provided that there is a balance between the economy, the society and the environment. During the third quarter of 2011, The Economist reported that â€Å"the global population is likely to reach 7 billion†. Due to the growing population of human beings around the world, increased in human activities could alter the climate condition of our natural environment. As a common knowledge, the existing energy sources in the United States are vital to the economic development and progress. In fact, a significant increase on the demand for energy would mean the need to increase the energy supply coming from different sources of energy. In response to the increasing demand for energy resources, the United States government is spending approximately US$500 billion each year in the development of energy sources alone. With the presence of sufficient energy supply, the local manufacturers will be able to produce consumer good items to meet the increasing local and international demand. For this reason, the U.S. Department of Energy has been relying over the use of different energy sources including: bioenergy, coal, electric power, fossil fuels, fusion, geothermal, hydrogen, hydropower, natural gas, nuclear, oil, solar and wind energy. The negative long-term socio-economic, environmental, and health benefits associated with the use of fossil fuel is more than the challenges associated with the use of renewable energy resources.

Compare Canadian Healthcare System with US Healthcare System Research Paper

Compare Canadian Healthcare System with US Healthcare System - Research Paper Example In this essay, the author will illustrate a brief descriptive analysis and critical evaluation of the considerable merits of the two systems. While, it is generally acknowledged that Canada’s system is inexpensive, others also contend that it is inferior to the US healthcare system in terms of availability and quality of care. The aim of this paper is not to prove who is better off than the other, but to offer valuable points for improvement for the greater welfare of the people. Funding. The main difference between the US and Canadian healthcare system is the way it is funded. In the US, various insurance agencies in coordination with the concerned governmental units would pay for the hospitalization and other medical expenses of the citizen, notwithstanding his or her own personal fund to cover every item in the bill (Shi & Singh, 2008). While in Canada, the government serves as the single payer for all the expenses incurred in the medical procedures of the citizen. For most cases, no charge shall be directed to the patient, although for pharmaceutical purchases a minimal amount may come from his or her own wallet. In this context, the Canadian system earns many significant advantages as the coverage is universal, and ‘less privileged’ citizens enjoy the same medical treatment as those with the wealthy members of society. Recent statistics demonstrate that life expectancy rate in Canada is higher than in the US by two years. It was noted that the latter is among the lowest among highly industrialized nations in terms of this scientific finding (Nolte & McKee, 2008). Costs. The role of the government in Canada’s healthcare system is much noticeable than in the US. The serious responsibility of the state to pay for the medical expenses of the people poses a challenge to the officials, yet places them in the position to be of much help. Available literatures declare that with Canada’s government as sole payer, efficient administ ration of healthcare costs is achieved. In the US, the multifarious insurers may actually lead to the confusion of the patient and physician, hence precipitating hitches on the way. Access. One great disadvantage to the Canadian health system, however, is the lowered number of physicians. This plight was attributed to the fact that most Canadian doctors would opt to practice the profession in the American soil as the financial rewards are way too attractive than in their homeland. This premise may also be contributory to the imbalance of the number of generalist and specialist physicians in the US. In any event, equilibrium of these medical professionals is necessitated to provide holistic medical treatment to patients. By instituting some reforms in the American set-up, generalist doctors will proliferate and will be available to the general public (Schoen, Osborn, Doty, Squires, & Applebaum, 2009). It was also reported that in the area of technological advancement in healthcare, C anada’s system is less important. Few numbers of scanner and MRI machines may cause delay in the service and would cause for insufficient diagnostic reliability. Above all, due to these reasons, Canada’s healthcare providers are criticized for the longer wait periods that their clients experience. Another negative aspect raised against both systems is the intentional inaccuracy of diagnostic results so as to generate profit.

Atomic Weight of Magnesium Lab Report Example | Topics and Well Written Essays - 250 words

Atomic Weight of Magnesium - Lab Report Example The ChemLab was used to simulate the reaction involving Magnesium and Hydrochloric acid, which produced hydrogen gas, magnesium and chloride ions. By measuring the amount of gas produced, the molecular weight of Magnesium was calculated. Using ChemLab, 30 ml 2M HCl was added to 300 ml H2O. 10 mg Magnesium was then added to the solution. After measuring the amount of Hydrogen produced, the molecular weight (grams per mole) of Magnesium was calculated. The calculation of the molecular weight using the weight of magnesium and the amount of hydrogen gas released was facilitated by the used of the balanced equation describing the reaction between magnesium and HCl: This means that a mole of magnesium needs two moles of HCl to produce a mole of hydrogen gas, a mole of magnesium ion, and a mole of chloride ion. This direct relation is applicable only when the parameter compared is the

An application of McLuhan's theories to television Essay

An application of McLuhan's theories to television - Essay Example In Understanding Media McLuhan declared that the media are extensions of our senses or faculties. He looks into how each of the media are capable of rearranging our social lives even to the extent of depersonalization and absolute alienation. The Mechanical Bride asserted that the real significance of the media lay in their ability to modify human relationships and perception. Although Understanding Media was published as early as in 1964, McLuhan had predicted along with his famous theory of media as extensions that one day there could be the collectivization and corporatisation of all information. It has been rightly pointed out that the Internet is nothing but an extension of one's powers of cognition. We open the 'home page' of a person the moment we choose to think of him. Then we proceed to click on links if need be. The retrieval of information in good time from the vast store house of the human brain is the pioneer google! Of the many theories that McLuhan has propounded, that of hot and cool media has gathered a lot of attention, especially in the light of the advent of computers which defy McLuhan's classification in the sense that it can be both hot and cold or neither hot nor cold. Before one discusses the complexities involved in the issue, a brief look at what McLuhan actually said in Understanding Media (1964) would be handy: A hot m... Telephone is a cool medium, or one of low definition, because the ear is given a meager amount of information. And speech is a cool medium of low definition, because so little is given and so much has to be filled by the listener. On the other hand, hot media do not leave so much to be filled in or completed by the audience. Hot media are, therefore, low in participation, and cool media are high in participation or completion by the audience (23). Communication is an ever growing phenomenon and is commensurate with the ways by which societies evolve. Although one can say that the moon and the tide communicate it has more to do with natural phenomenon than communication; the ant that discovers a drop of honey locks antennae with another that comes its way, but this apparent act of empathic communication is, according to Edward O. Wilson, based purely on genetic programming1 and not on will (the ant cannot choose not to communicate); only man can choose not to communicate, to communicate and yet not communicate, to lie, to imagine. The spectrum of possibility is too numerous to enumerate. So, as long as it is a human being who is the Receiver of the Sender's (mass medium) message, what if the former treats the hot as cool and vice versa. What if the silence from the other end of the telephone is construed as an acceptance of one's invitation to romance What if the very heat of the medium in describing everything makes the viewer turn off his sense/sensibility saying the medium is not cool enough McLuhan's theory sounds original but not comprehensive. It seems to lack an attention to corollaries. McLuhan's other observations that complement the basic premise of hot and cool media are more illuminating. He says that a

Civil Disobedience Paper Essay Example for Free

Civil Disobedience Paper Essay Throughout US history, there were many occurrences performed by people that helped define American Identity. Some of the many aspects that helped evolve characteristics of American identity are civil disobedience, freedom of religion, and immigration. Historical happenings throughout time helped create how the US is today, and why certain freedoms are allowed. Civil Disobedience is one of the important aspects of american identity. Harriet Tubman played a great role in performing civil disobedience involving her freeing slaves. Harriet had a huge bounty on her head and still she rebelled against the law, rescuing more slaves. Henry David Thoreau also performed a part in the act of civil disobedience when he refused to pay taxes, because of his opposition to the Mexican-American War. He wrote an essay Resistance to Civil Government stating that citizens have the right to disobey the law if the law was considered unjust. Furthermore, Womans rights is another example of civil disobedience. Women werent treated as equal as men and were denied the right to vote. In 1848 the Declaration of Sentiments had 12 resolutions that called for equal treatment of women and men under the law and voting rights for women. Overall, civil disobedience plays a huge role in American identity. Freedom of religion is another aspect that highlights american identity. Many people came to America in search of religious freedom. Colonists wanted a chance to worship freely and have a religion they wanted to take part in. When the pilgrims came to American their goal was to escape the persecution of the puritans. Later on many religions began to disperse everywhere and therefor, population began to grow in America. The Salem Witchcraft Trials, and the Great Awakening of the 1730s played a great role in influencing freedom of religion. America became a refuge for those who wanted religious freedom and became a home to the many people that had the chance to improve their lives. Overall, religious freedom is a huge aspect defining American Identity. Since before America’s founding, immigration has been part of the American identity. In 1845, potato famine in Ireland stopped plants from growing and many families were starved and wished for an escape, nearly 3.5 million Irish migrated to America during the 1820s through the1880s. The Irish weren’t the only immigrants that migrated to America. The Germans had come to America during World War 1 in order to better their lives. Immigrants with money would buy farms in the country, and immigrants with very little money would stay in the city, mainly in New York. By 1855, New York homed at least seventy percent of the New York population. Many immigrants have come to America and still have many coming in and out of our country nowadays. Overall civil disobedience, freedom of religion, and immigration are just a few of the many traits given to the US over time. Because of all these happenings that have occurred in the US, we as citizens have many rights. Here in the US we are known to have different yet unique identities, all thanks to the acts of rebelliousness and righteousness throughout US history.

The Third And Final Continent Essay

The Third And Final Continent Essay The character I have chosen for analysis from Jhumpa Lahiri short story, The Third and Final Continent, is the narrator, a very dynamic character who adapts to the traditions and lifestyles of the continents he travels to especially America. The narrator exhibits the most characteristics than any other character in the story because he is talking about his life and the actions that he takes when encountering a certain obstacle. The narrator also shows the most change than any other character. Living from one continent to another continent and then to another continent again can dramatically change how a person lives, thinks, and even eat. Despite all the changes that he experiences he still retains some traditions from his culture of origin with the help of a stranger that he meets. This is a positive characteristic that distinguishes the narrator from any other character in the story. The narrators life contrasts somewhat to other immigrants because they must all undergo a certain t ype of change and must worry about the passing of traditions to their American born children. The life of the narrator is a clear example of what most immigrants must go through when living in a new continent. The tone of the narrator sounds somewhat non enthusiastic or plain due to the fact that both of his parents have passed away. He shows strong love and respect for his parents. Before we cremated her I had cleaned each of her fingernails with a hairpin. I had assumed the role of eldest son, and had touched the flame to her temple; to release her tormented soul to heaven (Jhumpa Lahiri 654). The narrator is also a very well educated man, a graduate from LSE (London School of Economics), and he also has a knack for learning new things. I attended lectures at LSE. I read every article and advertisement, so I would grow familiar with things, and when my eyes grew tired I slept (Lahiri 650-651). The narrator faces an internal conflict: how can he be a modern American Indian and retain some of the old traditional Indian ways at the same time? His quest continues with the birth of his son, afraid that his son will forget his Indian traditions. So we drive to Cambridge to visit him, or bring him home for a weekend, so that he can eat rice with us with his hands, and speak in Bengali, things we sometimes worry he will no longer do after we die (Lahiri 662). The narrator tells to his son the journey of himself surviving in three totally different continents as a way for his son to gain the morale that he needs to overcome any obstacle. There is evidence in the story which suggest that the narrator is trying to find solutions for his problem because he tries to retain some of his old traditional ways by eating egg curry and walking barefoot in the house and being modern by telling his wife that she does not have to wear her sari all the time. And took turns cooking pots of egg cur ry, which we ate with our hands on a table covered with newspapers (Lahiri 650). There is no need to cover you head, I said. I dont mind. It doesnt matter here (Lahiri 660). Cooking egg curry is his main way of keeping Indian tradition alive. He cooks egg curry in India, in the crowded room in London, and even in his new home in America. He can never abandon his roots and obeys every aspect of his Indian culture. I regarded the proposition with neither objection nor enthusiasm. It was a duty expected of me, as it was expected of every man (Lahiri 654). The neutral remarks that he makes towards his arrange marriage shows that he is a very religious man, keeping alive some aspect of his tradition to allow him to survive the toughest of times. The narrator is astounded when he finds out from Mrs. Crofts daughter Helen that his land lady is over a century years old. I was mortified. I had assumed Mrs. Croft was in her eighties, perhaps as old as ninety (Lahiri 657). He could not bare the fact of a widow living all alone by herself because he once had close encounters with a widow before which drove her insane, his mother. Widowhood had driven my own mother insane. What pained me the most was to see her so unguarded And so it was my job to sit by mothers feet (Lahiri 657). When he realizes that Mrs. Croft is very old and also a widow for so long he starts to take care of her as if she was his own mother. At times I came downstairs before going to sleep, to make sure she was sitting upright on the bench, or was safe I her bedroom (Lahiri 658). This shows the narrators strong bond between stranger and stranger which later strengthens his relationship with Mala. His encounters with his land lady, Mrs. Croft guided him with his new life in America. He shows admiration for Mrs. Croft because she has survived for so long while keeping all of her old traditions intact and passing them on to her children. She added that it was also improper for a lady of Helens station to reveal her age and to wear a dress so high above the ankle (Lahiri 657). This paves the way for how the narrator should live his life and teach his son about Indian traditions. Mrs. Croft also symbolizes the narrators mother saying that Maya is a perfect lady! (Lahiri 662), as though she is approving of Maya to be the narrators wife. For immigrants, the challenges of exile, the loneliness, the constant sense of alienation, the knowledge of and longing for a lost world, are more explicit and distressing than for their children. On the other hand, the problem for the children of immigrants, those with strong ties to their country of origin, is that they feel neither one thing nor the other (Lahiri 663-664). This quote from Lahiri herself is basically what the theme of The Third and Final Continent is all about. It strongly interprets the narrators character in the story as an immigrant and the emotions that he feels when he enters a new country. It also explains the inner conflict in which he is trying to overcome of being a modern Indian and a traditional Indian at the same time, while explaining to his son how important it is to keep a little bit of tradition alive within you. Although not every immigrants life in America can relate to the narrators, it is true however that they all must undergo some type of chan ge when living in a new country for the very first time.
