Experiment to Measure the Heart Rate and Ventilation Rate Before, During and After Moderate Exercise Essay

I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise. Experiment: 1. To start with the experiment we measured the persons resting heart rate and respiratory rate where there was no strain on the muscles. We continued to check both pulse and respiratory rates at 30 second intervals during the course of exercise. 2. We decided to make the length of each consecutive exercise 30 seconds long. Between each session we allowed the student’s pulse and respiratory rate return to their resting rates, otherwise the results would not be fair if both rates were higher at the start of the exercise. 3.  Throughout each exercise the student made sure that equal paces were maintained so that it would not affect the heart or respiratory rate in a different way. Immediately after exercise the subject sat down in a chair so that both the heart and respiratory rates could be taken. The pulse rate was measured first for 15 seconds, if we had taken the pulse rate for 1 minute the pulse rate would have slowed down. As soon as the pulse rate was taken we then took the respiratory rate for 15 seconds. We then waited for both rates to return to their normal resting rates before starting the next exercise. Fair Testing: Our experiment was about how the heart and respiratory rates are affected by exercise. Unless we use a stethoscope we cannot measure both rates directly. We measured the pulse rate on the carotid artery. This will keep the experiment fair because each heart beat set up a ripple of pressure which passes along the arteries. The ripple can be felt as a pulse as the artery’s muscular wall expands and relaxes. Measuring the pulse rate is measuring the subject’s hearts beats except there is minimal lapse between the beat and the pulse. The diastole and systole produce a very distinctive two tone sound which is very easily felt. So to make sure we do not count twice we will always count the first pulse of the two. (Boyle and Senior Pgs. 160 – 161) Tiffin (Northumberland College Notes Jan’12) Sources of Error: The sources of error in this experiment that we would have to include are: * Subject being fit / unfit †¢ Healthy / Unhealthy * Smoker / Non-smoker †¢ On regular medication * Drinker / Non-drinker †¢ Suffer from any illnesses * No ECG Monitor †¢ Male / Female We have to make sure that we keep the same person throughout. This is because every person has a different diet, fitness level, weight, stature or is a different gender. All these factors affect a person’s heart or respiratory rate. If the person was changed during the experiment the results would not be reliable or fair. The subject’s resting heart and respiratory rates would be different and their body’s reaction to exercise would also be different. The pace of the subject will affect their heart and respiratory rates. They may start off at a quick pace, but go slower when they begin to tire. The subject must rest between each exercise so that all the lactic acid and CO? can be carried away. The tiredness of the student will affect the pace at which the subject performs their exercise. This is why it is crucial for fair results throughout the exercise. It is also necessary to allow the subject to recover before carrying on with their exercise. We must measure the subject’s pulse and respiratory rates in the same position as we did their resting rates. If we do not, we would not get accurate results. If we were to take the subject’s pulse rate standing up the heart rate would rise because the muscles are working to keep the subject upright. The heart rate would have to work harder in order to keep their muscles working. We decided to measure the subject’s pulse and respiratory rates whilst sitting down because there would be no additional stress on their heart, which would increase their heart rate. Their heart rate should also return to its resting heart rate due to the decrease of muscle use. I have placed the results from our experiment in form of a table and will use the average results to form a graph. I have also prepared a graph to show the results throughout the exercise. As the results show the highest increase in the pulse rate is in exercise 2 where the pulse rises by 44 BPM and the respiratory rate by 8 RR. Thereafter it continues to rise by 40 BPM and 8 RR. We did however experience a higher respiratory rate in the second lot of results in exercise 4 where the respiratory rate did rise by 12 RR. During exercise, the subject’s heart rate, systolic blood pressure, and their cardiac output (the amount of blood pumped per heart beat) all increase to maintain a state of balance, known as homeostasis. Homeostasis is a self-regulating process by which the human body maintains internal stability under fluctuating environmental conditions. Blood flow to the subject’s heart, their muscles, and their skin increase. Sweat glands secrete a salty solution that evaporates from the skin, taking heat with it. Their body’s metabolism becomes more active, producing CO? and H+ in the muscles and consequently lowers PH. The subject breathes faster and deeper to supply the oxygen required by this increased metabolism. With strenuous exercise, their body’s metabolism exceeds the oxygen supply and begins to use alternate biochemical processes that do not require oxygen. These processes generate lactic acid, which enters their blood stream. The subject’s cardiovascular system, their breathing system and their muscles work in conjunction with each other in order to perform their tasks more efficiently. A vital process of exercise is respiration (the production of energy). Principally, respiration is the breakdown of oxygen and glucose into carbon dioxide, water and ATP. Aerobic respiration requires oxygen and has the ability to break down both fatty acids and glucose. Anaerobic respiration takes place when there is a lack of oxygen, a lactate is formed and fatty acids cannot be broken down. (Boyle and Senior Pgs. 62, Pg. 215 and Pg. 222) Tiffin (Northumberland College Notes Feb’12) Glucose + Oxygen Carbon Dioxide + Water – C6H12O6 + 6O? —–>6CO? +6H? O+Energy Oxygen is taken into the subject’s lungs and then diffused into their bloodstream. Cells need oxygen to respire so more oxygen needs to be transported to muscle cells. This then causes the subject to breathe more deeply. Thei r intercostal muscles (muscles in between the ribs) contract up and out, moving the subject’s ribs and diaphragm up and out (a sheet of muscle at the bottom of the thorax, chest cavity). This increases the subject’s space available in their lungs for air to fill. More air in the lungs means there is more oxygen, so that more oxygen can be diffused into the bloodstream. The number of the subject’s breaths increases too, to maintain a high concentration gradient. Heart rate also needs to increase to keep their blood flowing through the lungs. The subject’s heart and respiratory rates rise because during exercise, their cell respiration in the muscles increase, so the level of carbon dioxide in their blood rises. Carbon dioxide is slightly acid, the brain detects the rising acidity in the subject’s blood, their brain then sends a signal through the nervous system to their lungs to breathe faster and deeper. Blood flows from areas of high pressure to areas of low pressure. The area of high pressure is the pressure created by the contraction of the subject’s ventricles, which forces blood out of their heart into the aorta. Resistance is caused by friction between the blood and the vessel walls. Gaseous exchange in the subject’s lungs increases allowing more oxygen into their circulatory system and removing more carbon dioxide. The subject’s brain then sends a signal to the sinoatrial node (SAN) to make the heart beat faster. Heart rate is controlled by the SAN. The subject’s rate goes up or down when the SAN receives information via their two automatic nerves. (Boyle and Senior Pgs. 160-162) Tiffin (Northumberland College Notes Jan-Feb 2012) †¢ Their sympathetic or accelerator nerve which speeds up their heart rate. The synapses at the end of this nerve secrete noradrenaline. †¢ Their parasympathetic or decelerator nerve, a branch of their vagus nerve, slows down their heart rate. (Boyle and Senior Pg. 162) A negative feedback system controls the subject’s level of carbon dioxide. During exercise, their blood level of carbon dioxide starts to rise. This is detected by chemoreceptors situated in three places: the carotid artery, the aorta and the medulla. Nerve impulses travel from these receptors to the subject’s cardiovascular centre. In response, their cardiovascular centre sends impulses down the sympathetic nerve to increase the subject’s heart rate. Their heart rate returns to normal after the cardiovascular centre sends impulses down the parasympathetic nerve once carbon dioxide levels have dropped. Boyle and Senior Pg. 162) Tiffin (Northumberland College Notes Feb’12) At rest During Exercise These images illustrate the alveoli and a red blood cell during rest and activity. This is the site where the red blood cells exchange carbon dioxide molecules for oxygen molecules to transport throughout the body. Notice the increase of both molecules as activity increases. (Zygote Media Group, Inc. ) The heart’s natural pacemaker – the SA node – sends out regular electrical impulses from the top chamber (the atrium) causing it to contract and pump blood into the bottom chamber (the ventricle). The electrical impulse is then conducted to the ventricles through a form of ‘junction box’ called the AV node. The impulse spreads into the ventricles, causing the muscle to contract and to pump out the blood. The blood from the right ventricle goes to the lungs, and the blood from the left ventricle goes to the body. (SADS Sudden Arrhythmic Death Syndrome) Conclusion: I have concluded, with the evidence provided in the graphs and table, in which the pulse and ventilation rates do increase during exercise. Overall, the results confirm the initial prediction that the heart and ventilation rates increase during exercise and return to normal level shortly after exercise has been completed. Heart and ventilation rates increased during the high intensity exercise to feed the body’s need for more oxygen and energy have been decreasing gradually immediately after exercise has finished as the muscles did not need more energy than usually. It is important to take into account each individual’s personal health, fitness and lifestyle when considering the effects of exercise. Generally, the fitter the individual, more quickly the resting rate is achieved.

Environmental Impacts from over Population Essay

Introduction The population of human beings on this planet has been gaining exponentially, since the dawn of Man. A basic feature of an exponential increase is that the numbers increase faster and faster as the population doubles and redoubles, with each doubling occurring in the same amount of time (Wright, 2008), As the population continues to multiply, so do the impacts upon our environment and surrounding ecosystems. As human populations increase, the demands for food, supplies, and housing also increase. With these increased demands, there is now a greater strain upon our resources more than ever before. The question then becomes, what are the impacts upon our environment by our population situation, and is there anything that can be done to deal with the problems from this dilemma? Population Impacts As civilization has continued to grow and develop, so has the impact upon our environment by our exploding population. As mankind began to â€Å"modernize†, the Earth began to feel impacts by the choices made from its inhabitants. Beginning with the agricultural revolution, humankind became able to manipulate his environment (Sharp, 2000). During the agricultural revolution, man was able to plant and grow food. As societies were still nomadic in their nature, mankind would use the resources of the Earth to their fullest extent, and then move on to the next area. This started with slash and burn techniques, and for the first time, CO2 levels were modified (Sharp, 2000) As the population of the planet continued to surge, the next great impact upon the environment would be the industrial revolution of the 1800’s. With the boom of the industrial revolution across the world, the demand for natural resources and the impacts upon the environment would soar. More people and natural resources were needed to sustain the new industrial system and the needs of growing societies (Sharp, 2000). The impacts of the industrial revolution were great and vast. For the first time in our world’s history, we could see the potential impacts of using our natural resources and dealing with an ever-growing worldwide population. The effects of population growth upon the environment are becoming revealed at an alarming rate. Between 1960 and 1999, Earth’s population doubled from three billion to six billion people (Rand, 2000). The world has changed dramatically over the last several years. The landscapes and ecosystems that were present hundreds of years of ago are no longer in existence. We are consuming our natural resources at an alarming rate. In fact, many environmental experts believe that human beings have reached their carrying capacity of sustainable life. How do we meet the challenges of population growth and managing our natural resources without exploiting the environment? First, we must begin to invest in technology that does not degrade the environment (Sharp, 2000). This is very critical to the retention of a sustainable environment for our future. In the past, countries developed around their economic strength. This factor often meant that most nations did not consider long-term environmental impacts by their decisions. These â€Å"slash and burn† techniques by many nations have resulted in devastating consequences to our ecosystems. There are entire species that have become extinct, all in the name of economic progress. This short-term economic gain for many of these nations has resulted in effects that will be felt from generations to come. The eye of man can see the effects of population growth. It also can now project the effects of population demand in the future. One of the growing problems facing mankind today is global climate change. From glaciers melting, to rising oceanic temperatures, and even climactic weather events, the effects of population upon the earth, have impacted our future for many years. Research suggests that temperatures have been influenced by growing concentrations of greenhouse gases, which absorb solar radiation and warm the atmosphere (Rand, 2000). There is still a great deal that we can do to preserve the environment and place a halt to the devastating environment impacts of our population growth. Our sustainability not only depends on us meeting this challenge, but also presents an opportunity to provide for the future of our civilization. An encouraging note is the simple fact that many companies are now becoming â€Å"green† companies, meaning that they are attempting to be environmentally conscious and pursue policies that offer to protect and not neglect our environment. The answers to this problem are two fold. First, we must address the growing populations in the developing world. The populations in these areas are growing at an alarming rate. Many of these areas are already facing critical famines and food shortages of historic proportions. Unfortunately, efforts to implement policies that stress birth control have not been effective. We must address the growing populations in these areas, if we are to tackle the problems that population growth has created upon the Earth. The next problem we must address, if we are to maintain adequate sustainability upon the Earth, is our own consumption issues. As a nation, we are consuming natural resources at an alarming rate. We consume more energy per capita than any nation on this planet. Moreover, we must develop better land-use policies in the developed world. The â€Å"slash and burn† tactics of the past must be stopped and we must acknowledge the fact that we cannot destroy entire ecosystems that have taken hundreds of years to develop, and believe we can replace them by simply planting hundreds of trees that will take years to grow. The impacts of our decisions are great. The choice is clearly impacted by economic factors. As a nation, our demand for consumer goods is at a high level. While our population is growing at a slow rate, our consumption levels have never been higher. Many Americans do not focus on the environmental impacts of their decisions today. We must implement sound environmental policies that embrace this factor. The choices are clear for society. As the population of the world continues to soar, so will the stresses upon our environment. There will be a greater need for usable water, natural resources, and even greater energy demands. While these demands pose a potential calamity for the environment, they also create opportunity for new industries. As mankind begins to recognize the negative effects upon the environment by poor decisions and usage in the past, we as a society can create and environment that fosters the development of â€Å"green† industries and elect government officials that encourage policies that promote the well being of our environment. Conclusion The effects on our environment from our population are visible everyday. One need only look to the smog filled sky, or read the newspapers decrying the shortages of drinking water, and the battles that are ensuing to lay claim to that drinking water to realize the impact of the decisions that face us as a society today. We can change the way we live and stop the poor use of the environment, and we can control the growth of the population in third world countries, or continue the status quo. If we choose poorly, we will face an environmental impact that will test the sustainability, not only of our civilization, but also of our planet.

Technology: Boon or Bane?

Day by day, technology advances only to deteriorate the health of those who use it. In the past years, scientists have spoon-fed people of all ages with attractive gadgets. However, the truth is technology has made humans less well-rounded individuals. Technology is a wonderful thing; there are cell phones with internet access and the capability to take pictures and videos. With computers, all the information you could ever want is available within a few keystrokes of a search engine. Contradicting those points is, just like everything else in life. Nothing is ever perfect and technology has its share of flaws. There are calculators, search engines, online forums and instant messengers that are making us socially and mentally handicapped. Video games are giving gamers a false sense of reality and teachings of violence. Finally, technology has in the past and is being used for the wrong reason of destroying the whole universe using weapons of mass destruction. People have questions every single day, and it is very normal and healthy to ask questions. This promotes the mental wellness of a human being; it also helps you learn more information which contributes to your general knowledge. With the invention of search engines and online forums, it has become easier to get your question answered. This is an asset to humans, however a human can become socially undeveloped and not have the confidence to talk with a person face to face and ask a question. Instant messengers have also contributed to the fact that people find it easier to talk over the internet, rather than face to face. The same rule applies to the mental strength of mankind. Math homework is less than a challenge for students of today. They pick up their calculators, type in a few numbers and write the answer down on the page claiming to their teachers that they have applied all their mental faculties to the questions. Though this method is extremely convenient, it is ruining our brain’s full capabilities. In order for something to run efficiently it must be utilized. The calculator does not permit the brain to be exercised before it can function properly. Video games provide unending fun, but it also gives the player unrealistic views about life. Computer and video games have come a long way since Space Invaders and Pac Man. â€Å"†¦numerous studies show that video games, especially ones with violent content, make teens more aggressive† (http://www. pamf. org/preteen/parents/videogames. html). Today's games are much more complex and interesting, and the technology has advanced to the point where a gamer can become immersed within the game. Video games provide the players with false ideas about saving the world and resulting to violence as a method of solving your problems with others. In other words it is making gamers become too unrealistic about the life they live and glorifying an unreal world. Technology has been used for the wrong reason of destroying the universe â€Å"[It] has dominated warfare since the early 1900s† (http://www. newscientist. com/topic/weapons). Majority of the population must agree with that comment. During the final stages of World War II in 1945, the United States conducted two atomic bombings against Japan in the cities of Hiroshima and Nagasaki† (http://en. wikipedia. org/wiki/Atomic_bombings_of_Hiroshima_and_Nagasaki). The bombings were one of the earliest signs of a technological breakthrough which destroyed the earth, there is no doubt that it is evident to happen again, due to the technology advancing every day. Another recent example which is still fresh in our minds is t he event of 9/11, in which terrorists trained themselves on a computer to destroy the Twin Towers. With technology reaching insurmountable feats rapidly, it is destroying the planet and its inhabitants. Technology is deteriorating the well-roundedness of humans by allowing them to rely on manmade machines and become lethargic. Technology is making us socially and mentally dumb, giving false sense of reality. Weapons are being created using technology for the wrong reason of destroying the universe. For all those reasons it is suggested people should become further aware of the Trojan horse of today, which is technology.

Nutritional paper

a. How did your recorded protein intake compare with the recommendation of the CNPP? Well, if my protein intake would be compared to the Nutritional recommendation of CNPP, I am not only doing well, I was able to surpass the requirement. In fact my total protein intake is around three times than the required amount. By having such a high protein diet results to a healthy living because of the following reasons: Protein aids in the proper maintenance of body tissues, Protein composes a large part of our body’s muscles, system organs, enzymes and hormones; without which one’s body can never function properly. Without significant amount of protein in our body, we can never live because proteins are one of the primary building blocks, specifically hemoglobin, which helps to bring oxygen throughout the body. The body’s enzymes are also composed of Protein, which also composes antibodies to help our body fight against diseases and viruses. Also the body needs a lot of protein to develop well. Without protein the skin will rapture easily because it lacks Elastin, the specific macromolecule that gives elasticity to the skin. b. If your recorded protein intake was too high or too low, which foods might you change to achieve your goal and keep other nutrients in balance? Protein can basically be found in fish, meat, poultry, pork, lamb, shellfish, milk, cheeses, eggs, beans, tofu and many more. So basically if I lessen my food intake when it comes to the different kinds of food mentioned above, I can normalize my protein intake. Why normalize my protein intake, considering I mentioned a lot of benefits earlier in this paper? Every time I eat too much protein packed food, I am at risk of having high cholesterol, not only that but it also gives way to kidney complications. Considering that Protein filled foods have cholesterol, it also heightens the risk of having heart attack. c. Which foods in your recorded daily intake provide protein? As mentioned above, fish, meat, poultry, pork, lamb, shellfish, milk, cheeses, eggs, beans, tofu and nuts are examples of food that I eat that provides me with more than enough protein for my daily diet. d. Is the protein in each of these foods complete, or are they incomplete, thus combining to become complementary? Considering the fact that at the end of the day, I was able to eat tree times the recommended protein intake, I can definitely say that the protein in the food that I eat on a daily basis is complete. Not only that, but the food that I eat with protein has other food groups such as carbohydrates, and fats, hand in hand with vitamins and minerals that is good for my everyday diet. e. How much of your daily recommended protein intake did you achieve? Were you surprised by that number? If your protein is not where it needs to be, what can you do to bring it into the recommended range? Be specific. I was able to achieve 165gm (294.64 %) protein intake considering that the normal protein intake is 56gm (100%). I am surprised considering that I ate more than enough protein filled foods that what was recommended. Needless to say, I don’t need to increase my protein consumption but instead lessen it. f. Why is your protein intake within a recommended range important? What are the effects of too much protein? What happens if you consistently eat too little protein? If I eat less than what was recommended amount as I was explained above will hinder my body’s metabolism, weaken my muscle structure, weaken my immunity and decrease the amount of oxygen that flows through my blood. Another bad effect of too little protein intake would result to the slow rapture of the skin, and also my internal organs. g. Did your fiber total meet 100 percent of the recommendation for you as calculated by the CNPP website? I was only able to achieve a total of 71.79 percent of the goal when it comes to fiber intake. Since I barely passed my fruit and vegetable consumption requirement I was not able to take in enough fiber in accordance to the daily recommendation; considering that vegetables and fruits are the food groups which are considered fiber rich. Similar:Â  Nutrition h. Did you think your intake was too high, too low, or just right? Why do you think so? Fiber rich foods are important because they aid in proper digestion, plus they don’t have any bad effect in our body. So therefore it is not a question of having too much fiber but instead having too little fiber intake. Considering I was only able to reach 71.79 % of the recommended fiber intake, I think it is low and should be improved so that I can at least aid my body in the digestion of everything else I eat. i. Did your diet meet the minimum number of servings of foods from each fiber-containing group? Considering I ate enough vegetables and fruits to fulfill the daily requirement, I think I was able to eat enough fiber-containing food. The only problem is that I was not able to eat fiber-rich food. j. If you did not meet your minimum fiber requirement, which fiber-containing groups (fruits and vegetables) fell short of the recommended intake? Fruits can be considered the cause since I was only able to eat enough fruits to meet the requirement. Plus, not all fruits are as fiber rich as pineapples. k. Which specific foods provided the most fiber in your day’s meals? Which provided the least? Identify trends in your food choices that would affect your fiber intakes. Fruits and a various vegetables provided me with the fiber I needed. Grain has a small chance of having fiber but it still has some. But meat and milk has no fiber at all considering that they complete most of my diet would be the cause for my lack of fiber. l. What alterations might you make among your vegetables, fruit, meat and alternatives, or grain choices to increase the fiber in your meals? Possible alterations on my meals would be as follows: Eating oats, brown rice, mountain rice and unpolished rice instead of the normal type of grains; eating high fiber fruits such as Pineapples, Blackberries and Blueberries; eating meat that contains less fats so that my body wont need that much fiber to clean it out of my system; and eating a lot more vegetables, specifically the green type of vegetables. m. What contributions do meats and milk products make to the day’s fiber total? What advice about fiber would you give to someone who emphasizes meat and milk products at each meal? How would you tell him or her to change his or her diet? What foods would you tell him or her to include in his or her diet? Meats and Milk does not contain any fiber what so ever. Basically, if one prefers to eat an all meat and milk diet, one will not receive a single ounce of fiber in what they will be eating. Therefore I would suggest that the person increase their fiber consumption by eating unpolished rice, oats, fruits and vegetables. n. Did your meals include fiber-rich bean dishes such as chili, beans in a salad, or split pea soup? Anyone interested in obtaining fiber should find ways to eat some legumes each day. Unfortunately my diet does not contain much of all the beans included above, but knowing perfectly that I have to eat legumes such as beans I will decide to include it much more often than I already do. o. If you chose to drink fruit juice instead of to eat whole fruit, what would happen to the fiber content of your diet? If you chose to drink purchased fruit juice instead of to eat whole fruit, what would happen to the calorie content of your diet? There are some pros and cons when it comes to drinking fruit juice versus eating whole fruit. First of all, whole fruits contain more fiber than any juice drink can possibly have. On the other hand, fruit juices have fixed amounts of calories, vitamins, and carbohydrates such as fiber, therefore it is much easier to control ones intake of calories than simply estimating it when I eat whole fruits; since fruits are not all have the same sizes and nutritional content.

High Budget Deficits Essay Example | Topics and Well Written Essays - 1500 words

High Budget Deficits - Essay Example Budget deficits, on the other hand, are the amounts in deficit of what the individuals spending, government or even a companies or corporations spending are short of the planned incomes from the entities sources. In another name, deficit spending may be the other terminology of budget deficits. Over the past years, budget deficits of countries, most so the developing countries, have attracted a lot of publicity. This has been majorly witnessed over the past two decades of which financial restructuring and turbulence have been witnessed (Associated Press 2010). The country where the impact is witnessed is attributable to the assorted financial ills bedeviling such countries; the countries base their expenditures from high debts due to extensive borrowing, high and ever growing rates of inflation and investment problems attributed to poor investment and their poor growth performance of such investments (Associated Press 2010). The poor government financial position, most so in regards to budgets, results to poor economic growth rates. The factors that fuel these rates are the poor growth of government revenues due to poor collection measures and tools. The budgeting process, which is not well structured, is also blamed for it in a major proportion. Others include the levels of economic development, which is low and unstable. World macroeconomic shocks, like the Great Depression and poor ways in which the government controls its expenditure, have in the past been witnessed to impact on the government financial position (Associated Press 2010). The methods used to finance any form of budget deficit will always result into an imbalance in one way or the other. For instance, if local borrowing is used, then the crowding out effect of the private investments occur leading to the collapse of the private firms which may even end up causing more harm to the economy. The budgeting process of most countries has so many loops and is, therefore, responsible for most countrie s budget deficits apart from the government participation in most economies and even the other factors as discussed above. According to reports, it is in record that budget deficits have several impacts on some economic sectors, such as private consumption, private investments, the T-bill rates, current account, and even money supply into the economy (BBC 2010). The aspects that the deficit has impact on as discussed above are major pillars for the measure of any economic growth of a country. Budget deficits have been recorded to reduce money supply into the economy; this majorly results when domestic borrowing is given an upper hand (BBC 2010). Intensified domestic borrowing may also lead to the collapse of private sector firms as a result of crowding out effect. I may, therefore, comfortably conclude that budget deficits in any economy are harmful to economic growth rates since they lower the growth rates. The causes of budget deficit are many and they include most major governmen t stakeholders (individuals, companies, and corporations) who evade taxation. It is in record that many US firms use the fair share of the infrastructure by the government but they don’t pay their fair share of the taxation; they use the roads, defense, grants and even emergency services (BBC 2010). Despite the companies making huge profits from the countries resources, they try as much as they could to evade

Comparing and Contrasting File Systems used by Windows Essay

Comparing and Contrasting File Systems used by Windows - Essay Example This paper presents a comparison between the key file systems used by Windows Operating System - FAT16, FAT32 & NTFS and also provides a brief introduction on Encrypted File System. The File system in Windows can be selected at the time of installation of the Operating System, or at the time of creating a logical volume within a single physical hard disk or an array of hard disks using RAID 0, RAID 1 or RAID 5. Windows allows a very simple method to convert the file system of a logical volume from FAT 16 to FAT 32 or from FAT 32 to NTFS without taking down the server or loss of data. However, Windows doesn't allow a backward conversion from NTFS to FAT 32 or from FAT 32 to FAT 16. For a backward conversion, the disk needs to be formatted and volumes created again. The characteristics of a file managed by the Operating System in terms of size limitations & security depend upon the file system chosen. The File Allocation Table (FAT) actually is a registry of hexadecimal values that identify the location of clusters within a logical partition. This helps the operating system to locate all the clusters constituting a file. This process is important because all clus ters constituting a file are not stored at one place but are distributed across the entire Hard Disk Storage (a process called Fragmentation). The OS maintains two File Allocation Tables within a cluster such that if one is corrupted, the second can be used. The FAT assigns a hexadecimal address FFF7 to a bad cluster (due to surface or magnetic errors) such that the OS is able to recognize them while collating clusters to access a file. FAT16 has some distinct disadvantages that are addressed by FAT32 and FAT32 in turn have some distinct disadvantages covered by NTFS. The following section presents the differences among the three primary file systems and introduction to the other file systems that are supported by Windows XP, Windows Vista and Windows 2000/2003. File Systems supported by Windows XP and Windows 2000/2003: The FAT16 in earlier versions of MS DOS used to be 2 GB of logical partition (Volume) size but with the introduction of NT by Microsoft enabled it to support 4 GB of Logical partition (Volume) size. It has two primary limitations - length of file name and size of clusters in a 2GB/4GB partition. FAT16 supports a file size of only eight characters with three extension characters. No spaces in between characters were allowed. Moreover, the minimum cluster size in a 2GB/4GB partition is 32 KB. This lead to lot of wastage of disk space because file sizes of a few KBs used to block 32 KB clusters (A cluster cannot be shared; it is always dedicated to a file). THE FAT16 file system supported limited entries in the boot file and limited number of files per directory. These limitations of FAT16 were eliminated by Microsoft by
