Physics homework - Math Problem Example Thus as boat 1 is displacing more volume of water than boat 2, it has a higher buoyancy force subjected upon it. Clearly, this is evident from the fact that boat 1 is afloat whereas boat two is sunken. 2. The volume of the given ice cube of 10cm dimensions is 1000cm3. It is given that when the ice cube is floating in pure water, 1cm of it is sticking up above the surface of the water. This shows that the weight of the water displaced by the 9cm thick portion of water is equivalent to the weight of the ice cube. The 9cm thick portion has a volume of 9cm*10cm*10cm i.e. 900cm3. The weight of 900cm3 of pure water is equivalent to 1000cm3 of ice. If we suppose the density of liquid water to be 1g/cm3, then we have 900g of liquid water equivalent to 1000cm3 of ice. This gives us a density of ice as 0.9g/cm3, which is approximately equal to the real value of density of ice (~0.91g/cm3). When the excess 1cm thick part is cut off, the remaining portion of ice has a volume of 900cm3. The weigh t of 900cm3 of ice is 0.9g/cm3*900cm3 i.e. 810g. Now, for liquid water, the volume of water that needs to be displaced to have the same weight as that of the ice is 810cm3 (810cm3*1g/cm3 = 810g). This means that only 810cm3 of the total 900cm3 of the remaining ice will get immersed in water. The rest 90cm3 volume will remain above the water level.

Macro Economis - Essay Example | Topics and Well Written Essays - 2000 words

Macro Economis - - Essay Example Macroeconomics As noted above, this present paper is based on the concept of macroeconomics, which has been described by Bauman and Klein (2011) as the branch of economics that majorly deals with the wider perspective of the national economy rather than a single segment of the economy. With reference to the writings by Mankiw (2011, p23) macro-economic is stated as â€Å"a branch of economics that focus on the trends and movements in the entire economy,† and some of these movements and trends concern employment, inflation, price levels, rate of growth, national income, and gross domestic product of a particular country, or region/ economic block. In comparison to the other branch of economics, Chung et al. (2007) stated that microeconomics mainly focus on smaller aspects of the economy such as the behaviour of consumers and business organisations, and how this affects quantities and prices within a particular market. According to Buiter (2010), even thou the field of macroecon omics is broad, it largely focuses on two critical areas of studies, which include the study on the causes and repercussions of short-run business cycles on the national income and the study on determinants of long-run economic growth. Dale et al. (2010) stated that usually the central government as well as the large corporations, utilise macroeconomic forecasts and models primarily to develop and evaluate economic policies and business strategies. Macroeconomic objectives In the previous sub-section, it was stated that macroeconomics is simply a branch of economics that focuses on the wider aspect of the economy; however, Keynes (2011) further added that macroeconomics also concerns itself with the conscious and deliberate management of economic variables within an economy in order to attain certain objectives. It is of essence to note that macroeconomics relies on three critical policies to attain its objectives, and these policies include the monetary policies, fiscal policies an d supply-side policies. Monetary policies are defined by Krugman and Wells (2009), as measures that are adopted by the central government through the central bank in order to increase or decrease the supply of money in circulation while fiscal policies are the policies of the central government, which focus on the country’s budget and especially issues pertaining to borrowing and taxation. As for supply-side policies, they are mainly devised to ensure that the market works efficiently. According to the writings by Bauman and Klein (2011), they wrote that the top objectives of macroeconomics include price stability, exchange stability, full employment, growth of the economy, and the balance of payment equilibrium. a) Price stability According to Buiter (2010), the maintenance of price stability is crucial to the national economy because higher price levels contribute to various problems pertaining to consumption, distribution, exchange, and production. For example, inflation d istorts economic calculations as well as expectations and it generates varying problems in different sections of the economy. Moreover, Buiter (2010) stated that during inflation creditors lose while debtors gain. Furthermore, inflation strains the relationship between capital and labour, and the distribution of national income becomes

Wind Farm Development in the United Kingdom Essay

Wind Farm Development in the United Kingdom - Essay Example This research will begin with the history of wind farm development in the United Kingdom. Wind farm development in the United Kingdom owes its influence to a few litigations. Among them is the Kyoto Protocol, which legally binds, the United Kingdom to its treaty of reducing greenhouse gases emission. There are a number of recommendations the treaty offers to this effect, but the United Kingdom has made significant steps in energy harnessing from the sun, water and wind. By the beginning of 2012, United Kingdom had the capacity of producing close to 1000 mega watts worth of solar energy. Meanwhile, water mainly generates hydroelectric power with estimated potentials of 5000Gkh. The other factor is the situation in MENA countries. Fossil fuels are the most widely used sources of fuel even in the United Kingdom. The Middle East and Northern African countries are the greatest producers of oil in the world but at the same time prone to political and economic instability. In this regard, w hatever economic or civil situation purges MENA countries, affects the state of oil production. A good example of political instability is the recent rebellion of citizens against dictator leaders in Libya, Egypt and Tunisia. This makes relying on fossil fuels such as oil and biogas tricky. Then, there is the fact that use of fossil fuel leads to production of green house gases reducing the use of oil even further. The United Kingdom sees the need to find a source of fuel that is reliable – not dependant on factors such as political instability, non pollutant and easy to produce. ... Since there got some progress in wind farms establishment and subsequent production of wind energy, a lot had to be done (Mackay 2009, p. 79). The year 2009 saw the establishment of 211 of fully functional wind farms. There is a steady progress in wind farm development across the country. For the year 2012, the aim is to increase offshore wind production capability by building at least five wind farms with a potential capacity of producing 1300 mega watts of electricity. This will be a much welcomed addition to the current 6,580 megawatts produced by the 333 fully functional wind farms across the country. Examples of functional wind farms in the U.K include the Burbo Bank wind farm, Scroby Sands and the largest offshore wind farm in the world, Thanet wind farm at the coast of Kent. The government’s commitment to these projects is clear from the current budget allocation of over five hundred million pounds to offshore wind farms (Julia 2006, p. 103). Wind farm development has a large ecological impact both positively and negatively. Positive Ecological impact, of wind farm development in the U.K: Unlike other sources of energy, wind power does not require the use of another fuel or water for it to be produced. This ensures that when producing wind energy one does not require exploiting other sources of fuel (Dragoon 2010, p. 87). Wind power does not produce air pollution during production essentially making it a clean source of energy (Boyle 2004, p. 34). Building wind farms, therefore, means there will be less air pollution; this will give the environment ample time to disintegrate the already existing green house gases in the atmosphere. Studies indicate that, since the embrace of wind energy use, carbon dioxide emissions have reduced

An investigation of public health responses to diabetes Essay

An investigation of public health responses to diabetes - Essay Example This results in increased amounts of sugar in the blood, causing complications usually involving the heart and kidneys. (Wikipedia, 2011) There are three main types of Diabetes. Type 1 Diabetes, or insulin-dependent diabetes, occurs when the pancreas fails to secrete insulin, thus the glucose taken in from food cannot be broken down. The result is a buildup of sugar in the blood that causes complications like kidney failure, retinopathy, heart failure, and hypertension. A patient with this condition requires artificial insulin to be injected regularly in order to control the blood sugar levels. Type 2 Diabetes, or non-insulin dependent diabetes, is similar. In this case, the pancreas is able to secrete small amounts insulin, but the body’s cells cannot receive it. The result is identical. The sugar builds up in the bloodstream, and causes the above complications. The third type is Gestational Diabetes. This occurs in pregnant women only. During pregnancy, the overworked body o f the mother is unable to secrete the excess insulin required, leading to increased blood sugar levels. Women with gestational diabetes are most likely to have large babies. Diabetes is caused by different factors. Obesity is a big predisposing factor. In obese persons, insulin is less able to facilitate the entry of glucose into the liver and adipose tissues. In addition, fat buildup presents a suitable environment for circulatory overload. As sugar builds up in the blood, the density and concentration gradient increases, making the blood thick and viscous. This prevents it from properly circulating around the body. And because the hands and feet are the furthest from the pump center, the heart, they receive the least amount of blood. Lack of nutrients from the blood kills the tissue surrounding the area. Eventually, the hand or food necrotizes, or dies, leaving amputation as the only solution. Not surprisingly, most amputees are a result of Diabetes Mellitus. Heredity also plays a big role. If one of your ancestors or family members had a health history of diabetes, you have more chances of acquiring it, and as you age these chances increase. In spite of all these, the principal factor is a sedentary lifestyle. When your body lacks enough exercise, the heart pumps less blood to the extremities, causing tissue death. (Black, 2001) Classic signs and symptoms of Diabetes are increased thirst, increased hunger, and frequent urination. The thirst occurs when the body mistakes the concentration of sugar in the blood for lack of water, thus it triggers the thirst center in the brain, causing the person to drink more water, which in turn causes him to urinate more. The hunger occurs because the cells cannot utilize the sugar and nutrients, causing them to â€Å"starve†. The body interprets this as lack of food; hence, the person eats more and more. Increase of blood sugar also affects the eyes. Absorption of glucose causes the lens to change shape, resulting in vision changes. The heart usually suffers the most. Because of an increased workload, the heart muscles grow, causing cardiomegaly. As this progresses, the heart, out of exhaustion and overwork, eventually gives up and stops pumping, causing heart failure, and death. Heart attacks are common in chronic high blood pressure. Kidney failure also occurs. The main job of the kidneys is to remove waste from the blood and return the cleaned blood back to the body. In diabetes, the high levels of sugar damage the nephrons, the

HRD 495 Essay Example | Topics and Well Written Essays - 750 words - 1

HRD 495 - Essay Example Fourth is being a capacity builder in order to do culture and capability audits of the organization. Fifth is being a strategic positioner which involves constructing HR reactions that are in line with the external requirements (Jackson, Schuler & Werner, 2012). With the changes in the nature of business, there has been a refocusing and expanding in HR roles. In order to meet the expectations of organizations, senior HR leaders have to react by recognizing and acquiring the competencies necessary for their dynamic functions. The major additional competencies required by senior HR leaders are leading change, strategic thinking and effective communication. Strategic human resource management is formulated to aid companies in meeting the various needs of their employees while also promoting company goals. SHRM is a component that is valuable in ensuring organizational success as it helps in attaining a competitive edge as pertains to flexibility, cost and quality. It is therefore necessary for SHRM to include the individuals that the organization is involved in business with. It is through them that sustainability can be attained by creating values that could not be implemented by indirect and direct competitors. Organizational success could also be attained by continuous investment by an organization in its image or reputation, emphasizing on the need for sound HR practices and policies and adjusting them with the business strategies through SHRM. Therefore, SHRM is not merely a strategy that is centered on the organization’s human aspect but is a holistic approach which builds on the human asset as value-creating factors (Ivan cevich, 2010). It is an employer’s aim to hire the best person for a particular job irrespective of their age. There have been a lot of misconceptions regarding hiring older workers pertaining to productivity, health, up-skilling, and blocking

Googles Mission and Values, an Analysis Essay Example for Free

Googles Mission and Values, an Analysis Essay Google is a 21st century company even though it was founded in 1998 with a simple mission statement; Google’s mission is to organize the world‘s information and make it universally accessible and useful (Google Inc, Quick Profile, 2010,  ¶ 1). Google has one vision: to accomplish it mission by providing the best web based services to its end users. According to the Google on its corporate website, there are ten things they (Google) know to be true that are the keys to their success (Google Inc, Our Philosophy, 2010,  ¶ 4-17) 1.Focus on the user and all else will follow 2.Its the best to do one thing really, really well. 3.Fast is better than slow. 4.Democracy on the web works. 5.You dont need to be at your desk to need an answer. 6.You can make money without doing evil. 7.Theres always more information out there. 8.The need for information crosses all borders. 9.You can be serious without a suit. 10.Great just isnt good enough. What does all this mean in relation to the espoused values and vision of the company? This question requires a closer look. History What a grand endeavor founders Larry Page and Sergey Brin undertook when they founded Google. Googles mission statement seems almost untenable. Both the founders are brilliant engineers and in light of the advancement of technology and their pension for understanding algorithmic math, they built the first Google search engine. Little did they know how the grand ideals encapsulated in Googles mission statement could really change the face of the world in which we live, based on the computer coding to search the web more efficiently, but how did that happen? Before Google, from 1994 to 1997 web search was hit or miss using such services as MOSAIC, Wandex, Webcrawler, Infoseek, Lycos, Altavista, Magellan, Excite, Inktomi, Ask Jeeves, Northern Light Snap, Yahoo, and other smaller search engines. In 1998, that changed with the Google algorithm (Viney, 2008). Once Google was unleashed into the wild of the World Wide Web, it quickly took its place at the top of the search engine services as the best. To give credence to this fact the very name of the company has become a verb. Very few that live in a wired world have not heard the phrase Google it in relation to finding an answer on the internet. Google was so far ahead of its times even James Jenny, reviewer of the book by Jeff Jarvis What would Google Do? states I realized I was reading a glimpse of the future after gaining an understanding of Googles grand goal, its mission, organizing the worlds information (Penny, 2010, pg 810). Philosophy Googles founders simply had an understanding of what could be and found a means to try to accomplish it. They idealized that the world would be a better place if everyone, yes everyone, had access to the same information. A capitalism comparison seems appropriate here since it is based on the precept that the best minds can create the best product and that product will win the market. Google did just this in its creation and it has not only revolutionized the world of internet search, it has begun to see it mission statement to fruition. In the minds of the founders, free information leads to better ideas and actions for all of humanity. Better ideas that will lead overall to a better planet lead by the best thinkers that have the most influence over the direction of industry, politics, and other world opinions, all based on the precept of an unlimited worldview of information that is unlike the education systems in place today in most classrooms. Google espouses the possibility of an education that is not myopic from the point of view of a countrys agenda as can be seen in the teaching of Tiananmen Square in China where none of the textbooks and public media will show the atrocities that happened that day in 1989 as just one example (Richelson and Evans, 1999). Analysis So how has Google fulfilled its vision, mission, and the edicts of it companys culture? The answer is not simple and it would require a PHD dissertation to delve into Googles proposed failures, but even longer, to qualify and quantify its impact of the good it has brought to the world as a whole. It does seem prudent to quickly point out a few of it missteps. A couple of examples are: 1.Google Buzz a Twitter like clone had unintentional consequences for Gmail users because it shared personal information by default with everyone in the users contact list without the consent of the Gmail user. 2.Google Wave was an attempt to redefine email. However, recently Google decided not to continue development due to lack of interest by its end users. All of this has been possible due to Google’s corporate culture that encourages its employees to communicate freely, innovate constantly, and requires that 20% of every employee’s work week be spent working on personal projects without the direction or oversight of management. Gmail came from this directly as did Buzz and Wave. Even Google’s communication with the rest of the world is open and direct. In a recent blunder by Google’s street view project, individuals’ personal information was collected by Google which in some cases included entire emails, passwords, and other data that was inadvertently broadcast by individuals’ unsecured wifi routers. In response to this Google admitted in earnest that it had done so, but that it did not mean to do it and made every attempt to correct the problem. They were up front enough that even the FTC â€Å"forgave† Google for this unintended trespass after they investigated the issue (Forbes, 201 0). Conclusion Overall Google has lived up to its mission and values, both internally and externally. It allows its employees to spread their wings, work in an open environment that promotes ingenuity, and encourages open communication. Google also communicates openly with world governments and humanity as a whole. Even in the wake of Google becoming a public company, it has not lost sight of what makes it special. Google indeed lives up to the ideals it espouses in all respects.

Study Effectiveness Of Nebulization Improving Childrens Respiratory Status Nursing Essay

Study Effectiveness Of Nebulization Improving Childrens Respiratory Status Nursing Essay Data analysis is the systematic organization and synthesis of research data and testing of research hypothesis using those data. Interpretation is the process of making sense of the result and examining their implication (Polit, 2004). Analysis is the method of rendering qualitative data meaningful and providing intelligible information, so that the research problem can be studied and tested, including the relationship between the variables. The study was conducted among children with wheezing to compare the effectiveness of nebulization with oxygen and without oxygen in improving their respiratory status. The data was collected, assembled, analyzed and tested and the findings based on the analysis are presented in this chapter. 4.1 Demographic Variables of Children with Wheezing: The age of the children with wheezing ranged between one month to five years. Out of this, 8 (16%) children were between the age group of one month to one year, 17 (34%) were between 1-3 years and 25 (50%) were between the age group of 3-5 years. Majority of the children were males (62%) and female children were 38%. 34 (68%) children belonged to nuclear family whereas 16 (32%) children belonged to joint family. LPG was used as the cooking fuel in all (100%) the houses (Table 4.1). 4.2 Family History of Smoking Habits: In nebulization with oxygen group, 5(20%) children had the family history of smoking habit. For majority (4) of children, grandfather was the person who smokes and for one child father was the smoking person. In nebulization without oxygen group, fathers of 3(12%) children smoke in the family (Table 4.2). 4.3 Family History of Respiratory Diseases: 5 (20%) children in the nebulization with oxygen group had a family history of asthma, out of which one person is on regular treatment. In nebulization without oxygen group, 5(20%) children had a family history of asthma and 3(12%) had a family history of COPD, out of which one person is on regular treatment (Table4.3). 4.4 History of Respiratory Diseases in Children: With regard to previous history of respiratory diseases, majority (64%) of children had wheeze associated lower respiratory infection (WALRI) in nebulization with oxygen group whereas in nebulization without oxygen group, 15 (60%) children had WALRI, .6 (24%) children had hyper reactive airway disease (HRAD) and 3 (12%) children had asthma in nebulization with oxygen group , whereas in nebulization without oxygen group,7 (28%) children had asthma and 3 (12%) had HRAD (Table.4.4). About the onset of respiratory diseases, 14 (56%) children developed respiratory diseases before 1year of age and 5 (20%) children developed between the age group of 1-2 years in nebulization with oxygen group whereas in nebulization without oxygen group, 10 (40%) children developed before 1year of age and 7 (28%) children developed between 1-2 years of age (Table.4.4). Regarding the duration of the disease, 14 (56%) children had the duration of disease less than a year and 6 (24%) had the duration between1-2 years in nebulization with oxygen group whereas in nebulization without oxygen group, 11 (44%) children had duration of less than 1 year and 8 (32%) had the duration between 1-2 years (Table.4.4). With regard to the regularity of the treatment, 3(12%) children in the nebulization with oxygen group and 6 (24%) children in the nebulization without oxygen group were on regular treatment. All these children were using inhalers. Majority of the children (66.66%) were using a combination of salbutamol -fluticosone inhaler in both groups and the rest (33.33%) were using asthalin alone (Table.4.4). 4.5 Immunization History: All the children (100%) in both groups were completely immunized. 4.6 Pre assessment of Respiratory Parameters in Nebulization with Oxygen Group: The initial assessment of respiratory rate of children in nebulization with oxygen group showed that 6 (24%) children were in mild distress, 6 (24%) children were in moderate distress and 13 (52%) children were in severe distress. In the assessment of oxygen saturation, 20 (80%) children had mild desaturation (95-97% in room air) and 5 (20%) children had moderate desaturation (90-94%in room air).In the initial assessment of wheezing, 12 (48%) children were having wheezing on terminal expiration and 13 (52%) children were having wheezing on entire expiration.The assessment of retraction showed that 16 (64%) children were normal, 8(32%) children had intercostal retractions and 1 (4%) child had intercostal and substernal retractions..In the initial dyspnoea assessment, 5 (20%) children were having mild dyspnoea and 20 (80%) children were normal (Table 4.5). 4.7 Pre assessment of Respiratory Parameters in Nebulization without Oxygen Group: The initial respiratory rate assessment of children in nebulization without oxygen group showed that 10 (40%) children were in mild distress, 8 (32%) children were in moderate distress and 7 (28%) children were in severe distress.

Assessment of retraction revealed that 24 (96%) children had no retractions, 1 (4%) children had intercostal retractions.Dyspnoea assessment showed that1 (4%) child was having mild dyspnoea and 24 (96%) children became normal (Table 4.6). 4.11 Comparison of Mean Difference of Pre and Post Assessment of Respiratory Parameters in Nebulization with Oxygen Group and Nebulization without Oxygen Group: 4.11.1 Mean Difference of Respiratory Rate in Nebulization with Oxygen Group and Nebulization without Oxygen Group: In nebulization with oxygen group, the pre mean values of respiratory rate was 41.68 and post mean value at 5 minutes was 40.4.Post mean values at 10 minutes was 37.76, at 15 minutes was 35.6 and at 30 minutes was 32.8. The mean difference between pre and post respiratory rate at 30 minutes was 8.88. This shows a significant reduction in respiratory rate after nebulization with oxygen. The pre mean value of respiratory rate in nebulization without oxygen group was 36.64 .The post mean value of respiratory rate at 5 minute was 36, at 10 minutes was 34.32, at 15 minutes was 32.48 and at 30 minutes was 30.96. The mean difference between pre and post respiratory rate at 30 minutes was 5.68. This shows a reduction in respiratory rate after nebulization without oxygen. Therefore, it can be inferred that the mean difference was high in nebulization with oxygen group comparing to nebulization without oxygen group. This showed that nebulization with oxygen is effective in reducing tachypnea among children with wheezing (Table 4.7). 4.11.2 Mean Difference of Oxygen Saturation in Nebulization with Oxygen Group and Nebulization without Oxygen Group: Oxygen saturation above 98% in room air is considered as the normal saturation level. The pre mean value of oxygen saturation in nebulization with oxygen group was 95.24. The post mean value of oxygen saturation at 5 minute was 96, at 10 minutes was 97.24, at 15 minutes was 98.08 and at 30 minutes was 98.32. The mean difference between pre and post oxygen saturation at 30 minutes was 3.08. This shows an improvement in oxygen saturation after nebulization with oxygen. The pre mean value of oxygen saturation in nebulization without oxygen group was 95.72 .The post mean value of oxygen saturation at 5 minute was 95.88, at 10 minutes was 96.68 at, 15 minutes was 97.36 and at 30 minutes was 97.08. The mean difference between pre and post respiratory rate at 30 minutes was 1.36. Therefore, it can be inferred that the mean difference was high in nebulization with oxygen group comparing to nebulization without oxygen group. This showed that nebulization with oxygen is effective in improving the oxygen saturation among children with wheezing (Table 4.7). 4.11.3 Mean Difference of Wheeze Score in Nebulization with Oxygen Group and Nebulization without Oxygen Group: Auscultation of normal vesicular breath sounds is considered as normal. The pre mean value of wheeze score in nebulization with oxygen group was 1.52. The post mean value of wheeze score at 5 minute was 1.4, at 10 minutes was 0.72, at 15 minutes was 0.56 and at 30 minutes was 0.44. The mean difference between pre and post wheeze score at 30 minutes was1.08. This showed an improvement in wheeze score after nebulization with oxygen. The pre mean value of wheeze score in nebulization without oxygen group was 1.32. The post mean value of wheeze score at 5 minute was 1.12, at 10 minutes was 0.56, at 15 minutes was 0.24 and at 30 minutes was 0.24. The mean difference between pre and post wheeze score at 30 minutes was 1.08. This showed that there was no mean difference in wheeze score in nebulization with oxygen group and nebulization without oxygen group. Hence, nebulization with oxygen and nebulization without oxygen has similar effect in reducing wheeze score among children with wheezing (Table 4.7). 4.11.4 Mean Difference of Retraction Score in Nebulization with Oxygen Group and Nebulization without Oxygen Group: Observation of normal chest movements is considered as normal. In nebulization with oxygen group, the pre mean value of retraction score was 0.4. The post mean value of retraction score at 5 minute were 0.4, at 10 minutes was 0.16, at 15 minutes was 0.08 and at 30 minutes was 0.04. The mean difference between pre and post wheeze score at 30 minutes was 0.36. This showed an improvement retraction score in nebulization with oxygen group. The pre mean value of retraction score in nebulization without oxygen group was 0.28. The post mean value of retraction score at 5 minute was 024, at 10 minutes was 0.12, at 15 minutes was 0.04 and at 30 minutes was 0.04. The mean difference between pre and post retraction score at 30 minutes was 0.24. This showed that there was no mean difference in retraction score in nebulization with oxygen group and nebulization without oxygen group. Hence, nebulization with oxygen and nebulization without oxygen has similar effect in reducing retraction score among children with wheezing (Table 4.7). 4.11.5 Mean Difference of Dyspnoea Grade in Nebulization with Oxygen Group and Nebulization without Oxygen Group: Grade 0 is regarded as absence of dyspnoea.
