Hydraulics Pneumatics Essays Hydraulics Pneumatics Essay Hydraulics Pneumatics Essay HYDRAULICS IN MISSILES Nowadays, the electro-hydraulic actuator plays an important role in some modern tactical missiles. High power, great robustness and high tracking precision are the most significant demands for the missile actuator. Therefore an advanced method of active disturbance rejection control (ADRC) is presented aiming at the dynamics of the system are highly nonlinear and have large extent of model uncertainties, such as tremendous changes in load. Firstly, a novel ADRC controller is designed for estimating and compensating disturbance based on the mathematical model of missile electro-hydraulic actuator. Then, the influence of rudder load on the system performance is analyzed in this paper. Simulation results show that the ADRC control approach can decrease the tracking error and enhance the robustness of missile electro-hydraulic actuator system when the rudder load changed tremendously. But the phenomenon of Anti-Control has disadvantageous effect on the transition period of actuator loop and evenly causes the system divergence. HYDRAULIC SUSPENSION IN BOGIES The application of oil-hydraulic actuators for active suspension of railway vehicles has been examined experimentally by using a 3-DOF half-vehicle model. The LQG control law was adopted, in which state variables were estimated from measurable ones on the actual railway vehicle. The results show the possibility that the controllable frequency range extends with the oil-hydraulic actuator. The addition of bogie acceleration measurement to body related measurement provides a significant advantage for the performance. When actual body weight becomes lighter than that of the controller design value, the control performance and the stability deteriorate. Therefore, it is recommended to use the empty car body weight for design of the active suspension controller. The control effect can reach to the maximum vibration isolation level by shortening the sampling period to 2 ms PNEUMATIC GREASE GUN A grease gun is a common workshop and garage tool used for lubrication. The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually on agrease fitting. The channels behind the grease nipple lead to where the lubrication is needed. The aperture may be of a type that fits closely with a receiving aperture on any number of mechanical devices. The close fitting of the apertures ensures that lubricant is applied only where needed. There are three types of grease gun: A grease gun (pneumatic) 1. Hand-powered, where the grease is forced from the aperture by back-pressure built up by hand cranking the trigger mechanism of the gun, which applies pressure to a spring mechanism behind the lubricant, thus forcing grease through the aperture. 2. Hand-powered, where there is no trigger mechanism, and the grease is forced through the aperture by the back-pressure built up by pushing on the butt of the grease gun, which slides a piston through the body of the tool, pumping grease out of the aperture. . Air-powered (pneumatic), where compressed air is directed to the gun by hoses, the air pressure serving to force the grease through the aperture. Russell Gray, inventor of the air-powered grease gun, founded Graco based on this invention The grease gun is charged or loaded with any of the various types of lubricants, but usually a thicker heavier type of grease is used. It was a close resemblance to contemporary hand-power ed grease guns that gave the nickname to the World War II-era M3 submachine gun. PNEUMATICS IN AIRCRAFT Bleed air in gas turbine engines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burners. While in theory bleed air could be drawn in any gas turbine engine, its usage is generally restricted to jet engines used in aircraft. Bleed air is valuable in an aircraft for two properties: high temperature and high pressure (typical values are 200-250Â °C and 275 kPa (40 PSI), for regulated bleed air exiting the engine pylon for use throughout the aircraft). 1] This compressed air can be used within the aircraft in many different ways, from de-icing, to pressurizing the cabin, to pneumatic actuators. However, bleed air is quite hot and when being used in the cabin or other low temperature areas, it must first be cooled or even refrigerated by the aircrafts environmental control system (ECS). Newer aircraft rely more on electricity, reducing the need for compressed air. Since most gas turbine engines use multiple compressor stages, some newer engines have the bleed air inlet between compressor stages to reduce the temperature of the compressed air.

Atomic Number 3 Element Facts

Atomic Number 3 Element Facts Lithium is the element that is atomic number 3 on the periodic table. These means each atom contains 3 protons. Lithium is a soft, silvery, light alkali metal  denoted with the symbol Li. Here are interesting facts about atomic number 3: Lithium is the lightest metal and the lightest solid element at ordinary temperature and pressure. The density of the solid near room temperature is 0.534  g/cm3. This means it not only floats on water, but is only about half as dense as it. It is so light, it can even float on oil. It also has the highest specific heat capacity of a solid element. Element number 3 has the highest melting point and boiling point of the alkali metals.Element number 3 is soft enough to cut with shears. Freshly cut metal is silver-colored, with a metallic luster. However, moist air quickly corrodes the metal, turning it dull gray and finally black.Among its uses, lithium is used in medications for bipolar disorder, to make lithium ion batteries, and to add a red color to fireworks. Its also used in glass and ceramics and to make high temperature lubricant grease. It is a coolant in breeder reactors and a source of tritium when atomic number 3 is bombarded with neutrons.Lithium is the only alkali metal that reacts with nitrogen. Yet, it is the least reactive metal in its element group. This is because the lithium valence electron is so close to the atomic nucleus. While lithium metal burns in water, it does not do so as vigorously as sodium or potassium. Lithium metal will burn in air and should be stored under kerosene or in an inert atmosphere, like argon. Dont try to extinguish a lithium fire with water as  it will only make it worse! Because the human body contains a lot of water, lithium will also burn skin. It is corrosive and should not be handled without protective gear.The name for the element comes from the Greek word lithos, which means stone. Lithium was discovered in the mineral petalite (LiAISi4O10).  Brazilian naturalist and statesman, Jozà © Bonifcio de Andralda e Silva found the stone on the Swedish isle Utà ¶. Although the mineral looked like an ordinary gray rock, it flared red when thrown into a fire.  Swedish chemist Johan August Arfvedson determined the mineral contained a previously unknown element. He couldnt isolate a pure specimen, but did produce a lithium salt from petalite in 1817.The atomic mass of lithium is  6.941. The atomic mass is a weighted average that accounts for the natural isotope abundance of the element.Lithium is believed to be one of only three chemical elements produced in the Big Bang that formed the universe. The other two elements are hydrogen and helium. Howev er, lithium is relatively uncommon in the universe. Scientists believe the reason is that lithium is nearly unstable, with isotopes that have the lowest binding energies per nucleon of any stable nuclides. Several isotopes of lithium are known, but the natural element is a mix of two stable isotopes.  Li-7 (92.41 percent natural abundance) and Li-6 (7.59 percent natural abundance). The most stable radioisotope is lithium-8, which has a half-life of 838 ms.Lithium readily loses its outer electron to form the Li ion. This leaves the atom with a stable inner shell of two electrons. The lithium ion readily conducts electricity.Because of its high reactivity, lithium is not found in nature as a pure element, but the ion is abundant in sea water. Lithium compounds are found in clay.Mankinds first fusion reaction involved atomic number 3, in which lithium was used to make hydrogen isotopes for fusion by  Mark Oliphant in 1932.Lithium is found in trace amounts in living organisms, but its function is unclear. Lithium salts are used to treat bipolar disorder, where they act to stabilize mood.Lithium is a superconductor at ordinary pressure at an extremely low temperature. It also supercondu cts at higher temperatures when the pressure is very high (greater than 20 GPa). Lithium displays multiple crystal structures and allotropes. It exhibits a rhombohedral crystal structure (nine layer repeat spacing) around 4 K (liquid helium temperature), transitioning to a face-centered cubic and body-centered cubic structure as the temperature increases.

World word II concepts - Essay Example In 1942-43, however, the U.S. Army Air Force went to war following a daylight precision bombing doctrine, then drifted toward area bombing, culminating in the Dresden raid and the firebombing of Japan. Conceding that "ethical restraints were not the most important limitation on terror bombing," Crane argues that their influence-amid doctrines, command pressures, and public attitudes--"cannot be completely discounted" (p. 8), and relies on official reports and statements to survey the range of views of strategic bombing among the senior airmen. USAAF trial night bombing missions are not noted, nor are such shaping forces as pacifist lobbying, the Army Industrial College, the Geneva air talks, the Nye Hearings, many, many boards and committees, and the Color/Rainbow War Plans. Nor will many students of propaganda agree that serious concern for public opinion in war-waging dates from the American Civil War. Much of the genealogy of RAF area-bombing lies out of view, from the Independent Air Force in World War I and interwar Air Staff processes, through various Bomber Command chiefs frustrations, the area-bombing scheme of Lindemann, Churchills science advisor, to the August 1942 Moscow Conference, when Churchill promised Stalin to bomb German cities in lieu of a "Second Front." However bellicose in style and rhetoric, Bomber Command chief Air Marshal Sir Arthur "Bert" Harris, was heir to that momentum. Whatever his influence was on Americans, especially on LeMay, the latter is cast as a kind of air-age Cromwell, and his considerable organizing and leadership skills are muted. After speculating how Nimitz or MacArthur might have reined in LeMay, Crane judges the twenty-first Bomber Command "more efficient" than the RAF Bomber Command, which is perplexing since their respective milieux varied widely, in duration, technologies, and distances. Whatever its debits, Cranes study is well worth reading. It describes how

Exploratory, Descriptive and Causal Research Essay

Exploratory, Descriptive and Causal Research - Essay Example imarily desires to develop insights into the problem Exploratory research must be an initial research to be conducted to clarify and then define the nature of a problem (Eden, Herrmann and Li, 2004). This is not supposed to provide conclusive evidence and subsequent research is expected. Meanwhile, descriptive research as the name implies, intends to describe the nature of business or market characteristics. It can also be used to produce data (Hughes, 2003), enable researchers to recognize associations among factors of interest. On the other hand, descriptive research cannot explicitly establish causal linkages. Mainly, surveys fall in descriptive research. Similarly, causal research is another type of business research method which aims to discover a cause and effect relationship by generating data beneath controlled conditions. Also it is capable of launching cause and effect between factors with a greater degree of certainty. The objectives as well as the research design and methods of the research problems stated in a-f, are critically analyzed and categorized according to the definition, classification, purpose, characteristics and outcomes of the three (3) research types - exploratory, descriptive and the causal research. 2. There are instances that the business team might want to find out the relationships of particular causal factors to the effects which they are predicting. In this case, they may utilize the causal research process. At the moment causes of the effects which are desired to be predicted will be fully understood, they can invariably improve the ability both to predict as well as to control the corresponding effects (Feldman, 1975). The stage in research by which researcher has to know the responses to the â€Å"why† questions without arriving to precise answers is part of the exploratory study. It is often the initial move in a series of actions that is planned by the marketing team. Exploratory research usually answers research

Comparison of Reports Essay Example for Free

Comparison of Reports Essay The ability to read and write reports is an essential skill in today’s world. Therefore we need to acquaint ourselves with the three main types of reports – Informational, Analytical, and Proposals. Informational reports mainly provide facts and figures while analytical reports go one step further and provide an analysis of the facts presented. Proposals are usually prior to writing a full-blown report and contain the methods on how a certain study is to be undertaken. No matter what our occupation is, one thing we will surely deal with is reports whether it be reading and evaluating them or writing them. Therefore it is of importance for a person to be acquainted with three main types of reports – Informational Reports, Analytical Reports, and Proposals. The most basic report is the informational report. As its name implies, an informational report’s main purpose and goal is to provide information in the form of facts, figures, or observations on a certain subject so that the reader will have a better understanding of the subject matter. For informational reports, it is very important to have accurate and significant facts gained from credible sources. An analytical report is similar to an informational report in that it also contains significant and informative facts gained from credible sources but it goes a step further because the author presents an analysis of the information cited in an effort to come up with ways of solving the issue. Usually the author will present facts and figures regarding the subject and then will provide a detailed analysis of these facts and figures in order to shed more light on the subject of the report. (Shurter et al. , 1965) A proposal on the other hand is something that is usually written prior to making a report or a study and states the importance or significance of undertaking that study. (Brown 1955) A proposal is similar to an informational report in that it must include preliminary sources where facts can be gained from. It is similar to an analytical report in the sense that it usually tackles an issue and it proposes to use a certain methodology or framework in which to analyze the data and thereby draw conclusions from. The main purpose for writing a proposal is if you want to undertake a certain study or report and wish to get a professionals’ opinion and advice on your idea for a report or to gain funding from different sponsors.

The Great Depression Essay -- essays research papers

The Depression was a period of time after the economic boom of the 1920's in America, when the economy went downhill. People lost money, jobs, shares, businusses went bankrupt and the farming industry suffered greatly. The Republic Government at the time lead by Hoover was still following policies of Lassez Faire so business was not getting the support it needed to get it back on track. The Republic Governments Protectionist policies were one of the causes of the great depression. There were trade problems associated with their protectionist policies. The Republic Government made high tarrifs on imported goods. This was to make sure that the Americans were buying their own products. Buying American products meant that they would be keeping the money in their economy instead of sending it to other countries. Other countries, now unable to export goods to the Americans retaliated by increasing their tarrifs on american goods. America could no longer export their goods to other countries. Mass production meant that there was more goods being produced than what needed to be but because other countries had high tarrifs on American goods, they could not be exported. Output became greater than demand so goods cheapened in price. American goods were not being sold. This resulted in cut-backs in production which meant that there was less employment available so people lost t heir jobs. Profits being made lessened and so did the value of shares. A lack of regulation in the stock market was also a cause of the great depression. Most shares that were changing hands were done so through borrowed money. Buying shares on the margin this way worked very well when share prices were rising. When prices began to slow down or cheapened in value however, trouble arose in the stock market. Seventy five per cent of share prices could be borrowed. This caused a lot of speculation which helped to increase share valuse further. The Federal Reserve Board gave easy credit to share holders and taxes were cut so that more money was available. This lack of regulation created more speculation which caused more share prices to increase. The farming problems in the United States increased and were one of the causes for the depression. Because of mechanisation there was over production of goods by farmers. There were large surpluses of food. It could not be exported because of high tarrifs... ...d unemployment was on the rise. people became homeless and had to live around the citys in slum areas they liked to call hoovervilles. suicide rose as a result of debts and the pressures being put on people who couldnt handle it. ill health rose as a result of poor hygene and living conditions. Elderly people were robbed of pensions and svaings and so had nothing to live for anymore. Women before the depression had begun getting involved in the stock market. so during the depression they lost money like the men did. They were only a percentage of the people involved in the stock market however, it was mostly still men. Women also stopped buying as many labour saving devices during this time. African Americans during the Depression were mostly still working on farms. They suffered like the rest of the farming population with debts and surplus produce. Hoover did not do all he could to stop the economic depression. he did what he believed in though, and he made attempts to get the economy back on track. He was only human in his actions, you can not do something if you dont feel it is right. and he was not going to help his nation if he thought he was going the wrong way about it.

Many films are a bad influence on young people Essay

The film industries of the world are developing day by day. Today there are so many films being produced that you can barely keep count. Some of them are for the benefit of the community but most of the films have a bad influence on the young people as well as on the community. These films are responsible for increase in violence, crime, illegitimacy in the society. And I completely agree with the statement that many films are a bad influence on young people because of the following reasons. It has been noticed that boys and girls are crazy of watching movies. And they spent averagely three to four hours in watching movies daily. This fast growing bad habit is expensive because of increasing electricity bill and the waste of precious time which can certainly be devoted to healthier, less wasteful and more gainful pursuits. The extreme setting in front of TV is harmful for education and health also. The studies are affected because youth like to watch television when parents are not there in home, and having no self-discipline. Many teens have shortsighted because of this. And it caused the problem like fat. Staying at home will let you become lazier. Our body needs to do sports, exercise etc The youth also try the actions done by heroes in the films. In the Indian films there is extreme level of violence, crime and other deviations from normal human behavior. The re-enactment shows shown on different channels of about robbery, murder etc, and are extremely dangerous for the country in future because youth learn about the new methods of criminal activities. Education and other experts have repeatedly found that the main source of eve teasing and assaults on girls in our towns and cities, in the market place and elsewhere, is the cinema. Young people see on the screen a hero running after a heroine, approaching and tempting her in subtle ways. Such talk and gestures naturally catch the attention of the immature cinema fans and affect their thinking and conduct. Thus, the social fabric and the morals of the young people are adversely affected. Another notable aspect of the situation is that whenever some enterprising producer presents a simple, true-to-life story, based on the works of famous short story or fiction writers as Prem Chand or Sarat Chandra, such films, and also art films free of glamour, seldom prove successful and prove to be flops at the box office. The modern audiences want songs and dances, spectacle and gorgeous costumes, love scenes and fights. What sort of citizens can the country hope to produce when the films the young see are totally misleading, lack aesthetical values. However, there are some positive effects of the films like movie â€Å"Tara Zameen Par† in which a child which is been weak in one subject can be good in other subject and the strictness of the parents on the weak subject can make the child mentally disabled. In the last movies and films are bad for the youth because positive effects are lesser than negative effects.

Indian Agriculture Essay

Indian agriculture had reached the stage of development and maturity much before the now advanced countries of the world embarked upon the path of progress. There was a proper balance between agriculture and industry and both flourished hand in hand. This situation continued till the middle of the 18th century. The interference from the alien British govt. destroyed the balance and the economy of the country was badly shattered. Therefore Indian agriculture in the pre-independence period can be correctly described as a â€Å"subsistence† occupation. It was only after the advent of planning (more precisely the advent of the green revolution in 1966) that the farmers started adopting agriculture on a commercial basis. THE ROLE OF AGRICULTURE IN INDIAN ECONOMY 1. Share in national income: at the time of the First World War, agriculture contributed two-thirds of the national income. After the initiation of planning in India, the share of agriculture has persistently declined due to the development of the secondary and the tertiary sectors. At 1999-2000 prices, the share of agriculture in GDP at factor cost was 27. see more:non farm activities 3% in 1999-2000 and 21. 7% in 2005-2006. 2. Largest employment providing sector: in 1951, 69. 5% of the working population was engaged in agriculture. This percentage fell to 66. 9% in 1991 and to 56. 7% in 2001. 3. Provision of food surplus to the expanding population: the ninth Five Year Plan set a target of increasing the food grains production from a level of 199. 4 million tonnes in 1996-97 to 300 million tonnes by 2007-08 to meet the consumption requirement of India’s estimated population of more than a billion. 4. Contribution to capital formation: since agriculture happens to be the largest industry in India, it can play an important role in pushing up the rate of capital formation. The policies advocated are: a) Transfer of labor and capital from farm to non-farm activities. b) Taxation of agriculture in such a way that the burden on agriculture is greater than the governmental services provided to agriculture. c) Turning the terms of trade against agriculture b imposing price controls on agricultural products, taxation or the use of multiple exchange rates that discriminate against agriculture. 5. Providing raw materials to industries: agriculture provides raw materials to various industries of national importance, like, sugar industry, jute industry, cotton textile industry, etc. 6. Market for industrial products: since more than two-thirds of the population of India lives in rural areas, increased rural purchasing power is a valuable stimulus to industrial development. 7. Importance in international trade: for a number of years, cotton textiles, jute and tea accounted for more than 50% of export earnings of the country. With economic progress and consequent diversification of production base, the share of agricultural goods in total exports has consistently fallen. It fell from 44. 2% in 1960-61to 10. 2% in 2005-06. A growing surplus of agricultural produce is needed in the country to: i) Increase supply of food and agricultural raw materials at non-inflationary prices. ii) Widen the domestic market for industrial goods through increased purchasing power within the rural sector. iii) Facilitate inter-sectoral transfers of capital needed for industrial development (including infrastructure) iv) Increase foreign exchange earnings through agricultural exports. THE NATURE OF INDIA’S AGRICULTURE At the time of independence, India’s agriculture was in a state of backwardness. Productivity per hectare and per worker was extremely low. The techniques employed were age-old and traditional. Because of low productivity, agriculture merely provided ‘subsistence’ to the farmers and had not become ‘commercialized’. Approximately 45% of the total consumption of the farmers came from their own production in 1951-52. This highlights the low importance of money in the village economy. These reveal that Indian agriculture was backward and qualitatively traditional in nature on the eve of the First Five Year Plan. Some of the causes responsible for the above state of affairs are listed below: 1. Feudal relations of production: at the time of independence, three types of land tenure systems existed in the country-zamindari, mahalwari and ryotwari. Approximately 57% area of the country was under the zamindar system, ryotwari came second with 38% and mahalwari was restricted to only 5%. 2. Usurious capital and rural indebtedness. 3. Labor market dualism: because of the excessive pressure of population on land, wages in the agricultural sector tend to be considerably lower as compared to the modern (industrial) sector. This leads to a labor market dualism. Low wages in the agricultural sector lead to low per-capita income and this, in turn, results in low labor productivity. 4. Outmoded farming techniques. 5. Fluctuations and instability in crop output: even now, approximately 60% of gross cropped area continues to depend on rainfall. Therefore nature continues to play a major role in determining the role of agricultural production. 6. Diversities in the agricultural sector and the problem of generalization: different regions exhibit entirely different characteristics so that no one plan can be conceived for all agricultural regions of the country. CROPPING PATTERN IN INDIA By crop pattern, we mean the proportion of area of different crops at a point of time, changes in this distribution over a period of time and factors determining this change in distribution. Cropping pattern in India is determined mainly natural factors like rainfall, climate and soil conditions. However, technological conditions have also played an important part. Some significant facts about the cropping pattern in India are summarized below: 1. Food crops including cereals, millets, pulses, vegetables and fruits cover nearly three-fourths of total cropped area. Of the total area under food grains, a large proportion is occupied by cereals. Of the total area of 121. 9 million hectares under food grains in2005-2006, the share of cereals was 99. 5 million hectares (i. e. , 81. 6%) 2. Rice is the most important food grain crop in India. 2005-0 6 it was grown on 43. 5 million hectares, which amounted to 34. 7% of total area under food grains. This shows that rice is grown on more than one-third of the total area under food grains. 3. The second important crop in India is wheat. In 2005-06 wheat was grown on 26. 6million hectares, which comes to 21. 8% of the area under food grains. 4. The combined area under jowar, bajra and maize declined in percentage from 28. 6% in 1950-51 to 21. 4% in 2005-06. 5. Area under oilseeds was 10. 7 million hectares in 1950-51 and 19millio hectares in 1985-86. To achieve self-sufficiency in edible oils, the govt. launched a no. of programs in 1980s. As a result of these programs, area under oilseeds increased rapidly to 26. 2 million hectares in 1998-99. In 2005-06, area under oilseeds rose to 27. 7 million hectares. 6. In commercial crops, the area under sugarcane increased from 1. 8 million hectares in 1950-51 to 4. 2 million hectares in 2005-06. The area under jute increased from 0. 6 million hectares in 1950-51 to 0. 8 million hectares in 2005-06. Area under cotton rose from5. 9 million hectares in 1950-51 to 8. 9 in 2005-06. TRENDS IN AGRICULTURAL PRODUCTION AND PRODUCTIVITY Agricultural production has two components- food grains and non food grains. In the index no. of agricultural production, the weights assigned to food grains and non food grains are62. 9 and 37. 1 respectively. The most important component in the food grains category is rice (weight 29. 7), followed by wheat (weight 14. 5). In non food grains category, oilseeds constitute the most important group (weight 12. 6). Sugarcane carries a weight of 8. 1 while cotton carries a weight of 4. 4. As far as food grains output is concerned, the total production increased from 50. 8 million tonnes in 1950-51 to 187. 0 million tonnes in the eighth plan, and further to 202. 9 million tonnes in the ninth plan. However, because of draught conditions in the first year of the tenth plan, 2002-03, the food grains output declined to 174. 8 million tones but again rose to 213. 2 million tonnes in 2003-04. However in 2004-05, it fell to 198. 4 million tonnes and stood at 208. 3 million tonnes in 2005-06. In the non food grains group, jute and cotton show slow and halting progress in both the periods. However, the production of oilseeds rose considerably in the latter half of the 1980s and certain years of the 1990s. It increased from 12. 7 million tonnes in 1987-88 to 27. 7 million tonnes in 2005-06. Production of cotton rose from 8. 4 million bales in the seventh plan to 19. 6 million bales in 2005-06. Sugarcane registered a more or less steady growth during the entire period 1950-51 to 2002-03, but its production fell sharply in 2003-04 and 2004-05. However, in 2005-06, it bounced back to touch 278. 4 million tonnes. Over the period 1950-51 to 2005-06, yield per hectare of all food grains has increased by more than three times from 552 kgs per hectare in 1950-51 to 1,708 kgs per hectare in 2005-06. Most significant increase has been recorded by wheat with its yield increasing from 655 kgs per hectare in 1950-51 to 2,607 kgs per hectare in 2005-06. While the productivity of maize has increased significantly during recent years, the productivity of jowar and bajra has increased relatively slowly. Productivity of pulses was only 585 kgs per hectare in 2005-06 which was only slightly higher than the productivity in 1960-61. A comparison of productivity levels of Indian agriculture with the levels in other countries shows how low the productivity in Indian agriculture is. India happens to be one of the largest growers and producers of most of the agricultural crops, but ranks very low in terms of yield. For instance, it has the largest area under rice and wheat in the world and the second largest producer of these crops. However, in terms of productivity, its rank is only 52nd in the world in rice and 38th in wheat. Not only is productivity in Indian agriculture lower than that in other countries, it is much lower than the potential. The causes of low productivity in Indian agriculture can be divided in the following three categories: I. General causes. 1. Social environment: it is said that the Indian farmer is illiterate, superstitious, conservative and unresponsive to new and modern agricultural techniques. The social environment of the villages is often stated to be an obstacle in agricultural development. 2. Pressure of population on land: this is partly responsible for the sub-division and the fragmentation of the land holdings. Productivity on small and uneconomic holdings is low. 3. Land degradation: almost 43% of land suffers from high degradation resulting in 33-67% yield loss while 5% is so damaged that it is rendered unusable. II. Institutional causes. 1. Land tenure system: in this land tenure system, it is difficult to increase productivity through technological progress. Land reforms should precede technical changes. 2. Lack of credit and marketing facilities: Indian farmers continue to produce the same output even at more attractive prices. On account of lack o marketing facilities or non-availability of loans on fair interest rates, the cultivators are not able to invest the requisite resources in agriculture. This keeps the level of productivity low. 3. Uneconomic holdings: most of the holdings are not extremely small; they’re also fragmented into a no. of tiny plots so that cultivation can be carried on them only by labor intensive ways. This results in low productivity. III. Technical causes. 1. Outmoded agricultural techniques: most of the Indian farmers still use outmoded techniques. Wooden ploughs and bullocks are still used by majority farmers. Use of fertilizers and HYV seeds are very limited. Indian agriculture is traditional. 2. Inadequate irrigational facilities: almost 60% of the gross cropped area depends on rains. Rainfall is often insufficient, uncertain & irregular. Thus productivity is low in areas depending wholly on rainfall. Even in areas having irrigational facilities, potential is not fully utilized because of defective management. Also with the ever rising cost of irrigation, small farmers can’t make use of the irrigational facilities. Following are some of the measures to increase productivity: 1. Implementation of land reforms: even though the land reforms have been introduced in India in the post-independence period, the results from it are pretty unsatisfactory. Therefore special efforts have to be made by the State to implement those reforms forcefully. Unless this is done, the tiller won’t have any incentive to invest in land and adopt new agricultural techniques. Thus, land reforms are the foremost necessity. 2. Integrated management of land & water resources: almost half of country’s soil is degraded. There’s a huge loss due to water-logging, salinization and human induced water erosion. This proves the urgency of the integrated & efficient management of our land and water resources. 3. Improved seeds: this play an important role in increasing productivity. E. g. :- HYV of wheat in Punjab, Haryana & U. P. therefore the farmers should be educated in the methods of sowing, manuring and irrigating the new HYV seeds. 4. Fertilizers: improved variety of seeds requires heavy doses of fertilizers. Indian farmers use only a tenth of the required amount. Use of fertilizers in ample quantities can push up the productivity. 5. Irrigation: use of improved seeds & fertilizers require proper irrigational facilities. It can also make multiple cropping possible in many areas & thus increase the productivity. 6. Plant protection: most of the countryside farmers are unaware of the medicines and insecticides to face the challenge posed by diseases & insects. The govt. should maintain its own technical staff to carry out the spraying of pesticides & insecticides at nominal rates. 7. Farm mechanization: it is generally maintained through farm mechanization, agricultural production can be increased. It results in increase in productivity of land & labor, reduction in costs, saving of time & increase in economic surplus. 8. Provision of credit & market facilities: use of improved seeds, fertilizers, irrigational facilities, pesticides, machinery, etc. requires substantial money resources which small farmers don’t possess. Thus it is necessary to strengthen the credit-cooperative sector. The commercial banks should be encouraged to lend more to small farmers. Cooperative marketing societies should be promoted to ensure better prices to small farmers. THE GREEN REVOLUTION A team of experts sponsored by the Ford Foundation was invited by the Government of India in the latter half of the second Five Year Plan to suggest ways and means to increase agricultural production and productivity. This necessity arose out of the need to increase agricultural production in the ace of continuing stagnation of production on one hand, and rapidly increasing demand on the other. On the basis of the recommendations of this team, the govt. introduced an intensive development program in seven districts selected from seven states in 1960 and this program was named Intensive Area Development Program (IADP). A district selected under IADP was required to possess qualities such as assured water supply, minimum hazards (like floods, drainage problems, acute soil conservation problem, etc), well developed village institutions and maximum potentialities for increasing agricultural production within a short span of time. The seven districts selected were West Godavari in Andhra Pradesh, Shahabad in Bihar, Raipur in Madhya Pradesh, Thanjavur in Tamil Nadu, Ludhiana in Punjab, Aligarh in Uttar Pradesh and Pali in Rajasthan—the first four were selected for rice, the next two for wheat and the last one for millets. This program was later extended to remaining states also by selecting one district from each state for intensive development. In October 1965, the net was widened and 114 districts were selected for intensive development and the program labeled as Intensive Agricultural Areas Program (IAAP). The period of mid-1960s was very significant from the point of view of agriculture. New high-yielding varieties of wheat were developed in Mexico by Prof. Norman Borlaug and his associates and adopted by a number of countries. These high yielding variety of seeds required proper irrigation facilities and extensive use of fertilizers, pesticides and insecticides. This new â€Å"agricultural strategy† was put into practice for the first time in India in the kharif season of 1966 and was termed High-Yielding Varieties Program (HYVP). This program was introduced in the form of a packaged program since it depended crucially on regular and adequate irrigation, fertilizers, high-yielding varieties of seeds, pesticides and insecticides. Initially it was implemented in a total area of 1. 89 million hectares. In 1998-99, total area under HYVP was 78. 4 million hectares. This was 62. 6% of the total area under food grains (data for later years are not available). IMPACT OF GREEN REVOLUTION Throughout the period of the green revolution, population was increasing at a rate of over 2% p. a, constantly pressing on the margin of cultivation of traditional agriculture. I. Impacts on agricultural production: As a result of new agricultural strategy, food grains output increased substantially from 81. 0 million tonnes in the third Plan to 208. 3 million tonnes in 2005-06. HYVP was restricted to only five crops-wheat, rice, jowar, bajra and maize. Therefore, non-food grains were excluded from the ambit of the new strategy. The production of wheat increased from 11. 1 million tonnes in the third plan to 69. 5 million tonnes in 2005-06. The overall contribution of wheat increased from 13% in 1950-51 to 33. 4% in 2005-06. Thus, wheat has remained the mainstay of the green revolution over the years. The average annual production of rice rose from 35. 1million tonnes in the third plan to 91. 0 million tonnes in 2005-06. The production of course cereals-jowar, bajra and maize-continues to remain static or has moved very slowly upwards. As far as pulses are concerned, their production was 11. 7 million tonnes in second plan, which rose to 13. 1 million tonnes in 2005-06. But even this is less than the requirement of pulses in India estimated at 17 million tonnes. The bulk of vegetable oil production in India is derived from nine cultivated oilseeds, namely, groundnut, mustard, sesame, safflower, nigerseed, soyabean, sunflower-forming the edible group-and linseed and castorseed forming the inedible group. The total production of oilseeds averaged 8. 3 million tonnes in the fourth plan and 11. 4 million tonnes in the sixth plan. To achieve self-sufficiency in edible oils, the govt. launched a series of measures towards the end of the sixth plan and the seventh plan. As a result of these, the average annual production of oilseeds rose from 11. 4 million tonnes in the sixth plan to 24. 7 million tonnes in 1998-99. This is also termed as the â€Å"yellow revolution†. II. Economic impacts of the green revolution i. Crop areas under HYV seeds needed more water, fertilizers, pesticides and certain other chemicals. This spurred the growth of the local manufacturing sector. Such industrial growth created new jobs and contributed to the country’s GDP. ii. The increase in irrigation created a need for new dams to harness monsoon water. The water stored was used to create hydro-electric power. This in turn boosted industrial growth and improved the quality of life of the villagers. iii. India paid back all the loans it had taken from the World Bank and all its affiliates for the purpose of green revolution. This improved India’s credit worthiness in the eyes of the lending agencies. III. Impact on labor absorption The adoption of new technology has reduced labor absorption in agriculture. In a large number of states, especially in those regions where there was abundant availability of labor, the growth of output was too slow to generate adequate employment opportunities. In high growth rate regions, labor was not plentiful and wage rate was high. The sudden rise in demand for labor in these areas induced mechanization and labor saving practices in general. Also, the HYVP is basically a land saving technology. By increasing the yield per acre, the new technology makes it possible to increase food production out of a given amount of land. This tends to increase the demand for labor. On the other hand, mechanized processes tend to reduce the demand for labor. In addition, the very dynamic possibility of increasing yields may itself encourage mechanization and in turn decreases the employment of labor. In recent years, a significant development in the pattern of rural labor absorption has been a shift away from crop production and into rural non-farm activities like agro-processing industries and other rural industries. IV. Political impacts of the green revolution India transformed itself from a starving nation to an exporter of food. This earned admiration for India in the committee of nations, especially in the third world. The green revolution was one factor that made Mrs. Indira Gandhi (1917-1984) and her party, the Indian National Congress, very powerful political force in India. [BOX: HIMACHAL PRADESH TOPS AGAIN IN IMPLEMENTATION OF 20 POINT PROGRAMMNE 17th July 2009 :Himachal Pradesh has done it once again. Yes, it has maintained the first position in the implementation of Twenty-Point Programme amongst all the States in the Country by attaining 92 percent achievement up to February during the financial year 2008-09, the last but one month of the financial year. This achievement is two percent more than the Gujarat, four percent Uttrakhand and five percent Andhra Pradesh the four top States that had been ranked in the implementation of this programme. The main thrust of the Twenty Point Programme is poverty alleviation, employment generation housing, education, family welfare & health, protection of environment and other schemes having a bearing on the quality of life, especially in rural areas. Under Employment Generation Programme, 8, 17,364 job cards have been issued in the State during the period thereby generating employment of 1. 54 crore man days by giving wages worth Rs. 171 crore . Under Individual Swaranjayanti Gram Swarojgar Yojna percent achievement of the State had been 517 as 8619 individual swarojgars have been assisted against a target of 1886 fixed for the year. Karnataka follows Himachal Pradesh in it whose percent achievements are 470. This speaks about tremendous performance of the State. Under Swaranjayanti Gram Swarojgar Yojna the achievement of the State is 318 percent. As many as 3486 individual ST Swarojgaries and 5612 individual women swarojgaries have been assisted from April, 2008 to February 2009 under this scheme. ] AGRICULTURAL FINANCE AND MARKETING Agriculture is an unorganized profession. Its success and failure depends, o a large extent, on climatic factors. Further, it’s not always possible to distinguish between productive and unproductive loans of the farmers. Because of these factors, banks did not show much interest in advancing loans to agriculture and allied activities for a long time and farmers were forced to depend on money-lenders and mahajans. NEED FOR AGRICULTURAL FINANCE Credit needs of the farmers can be examined from two different angles: i) On the basis of time : Agricultural credit needs of the farmers can be further classified into three categories:- a. Short term loans are required for the purchase of seeds, fertilizers, pesticides, feeds and fodder of livestock, etc. the period of such loans is less than 15 months. Main agencies of granting of short term loans are the moneylenders and co-operative societies. b. Medium term loans are generally obtained for the purchase of cattle, small agricultural implements; repair and construction of wells, etc. the period of such loans extend from 15 months to 5 years. These loans are generally provided by moneylenders, relative of farmers, co-operative societies and commercial banks. c. Long term loans are required for effecting permanent improvements on land; repayment of old wells, etc. The period of such loans extends beyond 5 years. Such loans are normally taken from Primary Co-operative Agricultural and Rural Development Banks (PCARDBs). ii) On the basis of purpose : Agricultural needs of the farmers can be further classified into the following categories: a. Under productive needs we can include all credit requirements which directly affect agricultural productivity. b. Farmers often require loans for consumption as well. Most of the farmers do not have sufficient income to sustain themselves. Therefore they have to take loans for meeting their consumption needs. Institutional credit agencies do not provide loans for consumption purposes. Accordingly, farmers are forced to fall back upon moneylenders. c. In addition to consumption, farmers also require loans for a multiplicity of other unproductive purposes. Since institutional agencies do not grant credit for such unproductive purposes, farmers have to seek assistance from moneylenders and mahajans. SOURCES OF AGRICULTURAL FINANCE AND THEIR RELATIVE IMPORTANCE Sources of agricultural finance can be divided into two categories: 1. Non-institutional sources 2. Institutional sources The non-institutional sources are the following- * Moneylenders * Relatives * Traders * Commission agents * Landlords The institutional sources comprise the Co-operatives, Scheduled Commercial Banks and Regional Rural Banks (RRBs). As far as co-operatives are concerned, the Primary Agricultural Credit Societies (PACSs) provide mainly short and medium term goals and PCARDBs long term loans to agriculture. The Commercial Banks, including RRBs provide both short and medium term loans for agriculture and allied activities. The National Bank for Agriculture and Rural Development (NABARD) is the apex institution at the national level for agricultural credit and provides refinance assistance tot eh agencies mentioned above. The Reserve Bank of India, as the central bank of the country, plays a crucial role in this sphere by giving overall direction to rural credit and financial support to NABARD for its operations. The first institution established and promoted was the institution of co-operative credit societies. By the end of 1976, there emerged three separate institutions for providing rural credit, which is often described, as the multi-agency approach. In 1982, NABARD was set up. India now has a wide network of rural finance institutions (RFIs). There are more than 30,000 commercial bank branches, 14,000 regional rural banks and about 1,00,000 rural credit co-operatives. As a result of the efforts undertaken by the govt., the share of non-institutional sources in rural credit, which was as high as 92. 7% in 1951, fell to 38. 9% in 2002. The share of moneylenders fell from 71. 6% in 1951 to 26. 8% in 2002. The share of institutional sources in rural credit rose correspondingly from 7. 3% in 1951 to 61. 1% in 2002. NATIONAL BANK FOR AGRICULTURE AND RURAL DEVELOPMENT (NABARD) The most important development in the field of rural credit has been the setting up of the National Bank for Agriculture and Rural Development (NABARD) in July 1982. It took over from Reserve Bank of India all the functions that the layer performed in the field of rural credit. NABARD is now the apex bank for rural credit. And therefore, it doesn’t deal directly with farmers and other rural people. It grants assistance to them through the co-operative banks, commercial banks, RRBs, etc. NABARD’s credit to State Co-operative banks, State Governments and RRBs outstanding in 2004-05 was Rs. 8,577 crore which rose to Rs. 12,763 crore in 2005-06.

the evaluation on smoking tobacco Essays

the evaluation on smoking tobacco Essays the evaluation on smoking tobacco Essay the evaluation on smoking tobacco Essay The evaluation of smoking As of 2008, there were 46 million adult smokers in the United States, according to the Centers for Disease Control (CDC). That means 20. 6 percent of people over 18 expose themselves to the disadvantages of smoking cigarettes (Livestrong. com). Smoking usually begins at a young age and progresses through the years. Research says adolescents begin to smoke because it makes them look cool. Peer pressure is a major factor in the question, why do adolescents begin to smoke. Smoking also ppeals to young adults because most parents wont allow smoking, therefore, it becomes an adventure, or experiment. Before an adolescent realizes how dangerous smoking really is, they become addicted and become another CDC statistic. Smoking harms nearly every organ of the body, causes many diseases, and reduces the health of smokers in general. As I am sure most are aware, smoking is a huge health risk. If youre not a smoker being around a smoker is almost unbearable. Smokers have a distinct overpowering smell. Weather you smoke or are around a smoker you cannot escape the smell. The smell locks to your clothing and is hard to get rid of, and nearly impossible to mask. Not only is the smell disgusting, it is also embarrassing. Having parents that smoke I know the embarrassment from experience, youre suddenly the stinky kid in class and no one wants to be the stinky kid. Not only does the smell bother a nonsmoker, but second hand smoke is Just as dangerous as lighting a cigarette up yourself. WebMD states, When you breathe in smoke that comes from he end of a lit cigarette, cigar, or pipe (side stream smoke) or that is exhaled by a smoker (mainstream smoke), youre inhaling almost the same amount of chemicals as the smoker breathes in (WeMD. om). Not only are smokers putting themselves at risk, but they put everyone around them at the same risks they are exposing themselves to. IVe always had the conception that smokers dont care about anyone but themselves. Not only do smokers not care that they are exposing themselves to many health risks, but they are putting the people around them at the exact same risks. There is an endless amount of health risk s to smokers, most of which can be deadly. The national cancer institute claims there are 50 known cancer-causing agents in tobacco smoke. Ehow health states, Smoking is the leading cause of cancer and cancer-related deaths, and it has been linked to stomach, throat, mouth, kidney, bladder, blood and lung cancer (Ehow. com). Along with cancers, the tar and nicotine in tobacco causes yellowing of the teeth, cavities, tooth loss, and leaves you with an unpleasant smile. Smoking harms nearly every organ of the body, causes many iseases, and reduces the health of smokers in general. Smoking is close to my heart because I have grown up with it my entire life. I hate smoking; to me there are no advantages to it. Some experts say that smoking decreases the risk of obesity, causes to tobacco use, the disadvantages outweigh the advantages. To me cancer, cardiovascular disease, odor, and dental problems hugely outweigh the very few advantages. Im not a smoker, and never will be so I will never truly understand why tobacco smokers put not only their health at risk, but others around them.

History of Automatic Teller Machines or ATM

History of Automatic Teller Machines or ATM An automatic teller machine or ATM allows a bank customer to conduct their banking transactions from almost every other ATM machine in the world. As is often the case with inventions, many inventors contribute to the history of an invention, as is the case with the ATM. Keep reading to learn about the many inventors behind the automatic teller machine or ATM. Hole in the Wall Luther Simjian came up with the idea of creating a hole-in-the-wall machine that would allow customers to make financial transactions. In 1939, Luther Simjian applied for 20 patents related to his ATM invention and field tested his ATM machine in what is now Citicorp. After six months, the bank reported that there was little demand for the new invention and discontinued its use. Modern Prototypes Some experts have the opinion that James Goodfellow of Scotland holds the earliest patent date of 1966 for a modern ATM, and John D White (also of Docutel) in the US is often credited with inventing the first free-standing ATM design. In 1967, John Shepherd-Barron invented and installed an ATM in a Barclays Bank in London. Don Wetzel invented an American made ATM in 1968. However, it wasnt until the mid to late 1980s that ATMs became part of mainstream banking. Luther Simjian Luther Simjian is best known for his invention of the Bankmatic automatic teller machine or ATM. Born in Turkey on January 28, 1905, he studied medicine at school but had a life-long passion for photography. Simjians first big commercial invention was a self-posing and self-focusing portrait camera. The subject was able to look a mirror and see what the camera was seeing before the picture was taken. Simjian also invented a flight speed indicator for airplanes, an automatic postage metering machine, a colored x-ray machine, and a teleprompter. Combining his knowledge of medicine and photography, he invented a way to project images from microscopes and methods of photographing specimens under water. He moved to New York in 1934 started his own company called Reflectone to further develop his inventions. John  Shepherd Barron According to BBC News, the worlds first ATM was installed in a branch of Barclays in Enfield, North London. John  Shepherd Barron, who worked for the printing firm De La Rue was the chief inventor. In a Barclays press release, the bank stated that comedy actor Reg Varney, star of TV sitcom On the Buses, became the first person in the country to use a cash machine at Barclays Enfield on June  27, 1967. The ATMs were at that time called DACS for De La Rue Automatic Cash System. John  Shepherd Barron  was the managing director of De La Rue Instruments, the company which made the first ATMs. At that time plastic ATM cards did not exist. John Shepherd Barrons ATM machine took checks that were impregnated with carbon 14, a slightly radioactive substance. The ATM machine would detect the carbon 14 mark and match it against a personal identification number (PIN). The idea of a PIN was thought up by John  Shepherd Barron  and refined by his wife Caroline, who changed John’s six-digit number to four as it was easier to remember. John  Shepherd Barron  never patented his ATM invention instead he decided to try to keep his technology a trade secret. John  Shepherd Barron  stated that after consulting with Barclays lawyers, we were advised that applying for a patent would have involved disclosing the coding system, which in turn would have enabled criminals to work the code out. In 1967, a bankers conference was held in Miami with 2,000 members in attendance. John  Shepherd Barron  had just installed the first ATMs in  England and was invited to talk at the conference. As a result, the first American order for a John  Shepherd Barron  ATM was placed. Six ATMs were installed at the First Pennsylvania Bank in Philadelphia.   Don Wetzel Don Wetzel was the co-patentee and chief conceptualist of an automated teller machine, an idea he said he thought of while waiting in line at a Dallas bank. At the time (1968) Don Wetzel was the Vice President of Product Planning at Docutel, the company that developed automated baggage-handling equipment. The other two inventors listed on the Don Wetzel patent were Tom Barnes, the chief mechanical  engineer  and George Chastain, the electrical engineer. It took five million dollars to develop the ATM. The concept first began in 1968,  a working prototype  came about in 1969 and Docutel  was issued  a patent in 1973. The first Don Wetzel ATM was installed in a New  York-based  Chemical Bank. Note: There are different claims to which bank had the first Don Wetzel ATM, I have used Don Wetzels own reference. Don Wetzel on the first ATM installed at the Rockville Center, New York Chemical Bank from  a NMAH  interview: No, it wasnt in a lobby, it was actually in the wall of the bank, out on the street. They put a canopy over it to protect it from the rain and the weather of all sorts.  Unfortunately, they put the canopy too high and the rain came under it. One time we had water in the machine and we had to do some extensive repairs. It was a walkup on the outside of the bank. That was the first one. And it was a cash dispenser only, not a full ATM... We had a cash dispenser, and then the next version was going to be the total teller (created in 1971), which is the ATM we all know today takes deposits, transfers money from checking to savings, savings to checking, cash advances to your  credit card, takes payments; things like that. So they didnt want just a cash dispenser alone. ATM Cards The first ATMs were  off-line  machines, meaning money was not automatically withdrawn from an account, as bank accounts were not then connected by a computer network to the ATM. Banks were at first very exclusive about who they gave ATM privileges to. Giving them only to  credit card  holders with good banking records. Don Wetzel, Tom  Barnes, and George Chastain developed the first ATM cards to have a magnetic strip and a personal ID number to get cash. ATM cards had to be different from  credit cards  (then without magnetic strips) so account information could be included.

Theory Testing Essay Example | Topics and Well Written Essays - 750 words

Theory Testing - Essay Example The basic principles in comfort theory are offering a holistic approach to nursing. This is achieved through supporting clinical decision made by health officials. Secondly, the theory defines nursing care and explains why a patient requires a specific health care basing on their health condition. The theory also elaborates the importance of family members and patient when participating in the nursing process for effective recovery of the patient (Walker, 2011). Comfort Theory Kolcaba described nursing as a process of determining a patient needs, making and implementing effective nursing interventions and assessing a patient comfort after nursing interventions. Evaluating may be through objective such as observing a wound as it heals or subjective which involves asking patient questions in order to understand if they are comfortable. Kolcaba also developed a theory to be used by nurses when caring for patients (Cook, 2008). This is a nursing theory developed by Katharine Kolcaba in 1 990s. Kolcaba broke down the theory into three forms. Ease: This involves placing patients in a comfortable state for them to feel relaxed. It involves solving issues that could cause stress or anxiety to a patient. Second is relief which is achieved through alleviating any pain that a patient may be experiencing. Comforting a patient through alleviating any physical injury on them that causes pain is an example of a relief. Lastly, transcendence is a state of comfort in which clients are able to overcome their challenges and recover their original form (Cook, 2008). Theory Testing Procedure Theory Testing Procedure involves qualitative analysis of comfort theory through critical thinking and assessing available data. The procedure involves exploring the richness, the depth and complexity involved in comfort theory. It is concerned with analyzing words, concept and impacts rather than the total number of patient under the given program. The procedures entail collecting information u sing relevant structures such as charts and maps and work out the procedure used in nursing. It also entails evaluating systems to determine whether they are effective enough in relieving, easing and transcendence a patient condition (Sitzman, 2011). The first step involves identifying a patient needs and investigating whether they are addressed. The second step is investigating the nursing interventions applied in comforting process. This is followed up by analyzing any extra measure taken to ensure the well being of a patient or enhance their comfort beyond their current conditions. Theory Testing Procedure should evaluate the methods used in identifying health seeking behaviors. These behaviors could be internal. In such case a patient has a health condition that could not be observed from outside. The second behavior could be external. This condition involves observable characteristics such as bleeding wound. The last step is analyzing the policies, practices and standards set i n comfort theory. These policies and practices should match a patient’s condition (Barry, 2005). Uses of Theory-Testing Outcomes The procedure is used to establish a patient comfort needs that have not been catered for by existing interventions or support systems. Nurses then design new interventions to handle unattended needs. The new intervention procedures are then taken into account to facilitate analysis in order to come up with immediate measures to enhance a patient comfort, and
