Research Paper on Viscosity Essay Example

Research Paper on Viscosity Essay Viscosity (internal friction) is one of the transfer phenomena, the property of the fluid bodies (liquids and gases) to provide resistance to the movement of one part to the others. As a result, there is a dissipation in the form of work heat expended in moving. Mechanism of internal friction in liquids and gases is that the randomly moving molecules carry pulse from one layer to another, leading to equalization of speed – is described by introducing friction. Viscosity of solids has a number of specific features and is usually considered separately. There are dynamic viscosity (unit in the International System of Units (SI) is Pa †¢ s, in the CGS system – Poise, 1 Pa †¢ s = 10 poise) and kinematic viscosity (unit in SI – m ? / s, GHS – Stokes off-system unit is Engler). The kinematic viscosity can be obtained as the ratio of the dynamic viscosity to density and by its origin is obliged to the classical methods for measuring viscosity, such as measuring time of the predetermined amount of flow through the orifice under gravity. Instrument for measuring viscosity called viscometer.

Proportionality factor, depending on the kind of liquid or gas, is called the coefficient of dynamic viscosity. The difference between viscous friction forces and dry friction is qualitatively significant, among other things the body in the presence of only viscous friction and an arbitrarily small external force is sure to come in motion, that is, for the viscous friction there is no stiction, and vice versa – under only viscous friction body, first moving, will never (within the macroscopic approximation, neglecting Brownian motion) stop completely, although the movement will slow down infinitely. Second viscosity or bulk viscosity is internal friction when moving in the direction of the momentum. It is effective only taking into consideration the compressibility and / or due to the heterogeneity of the second coefficient of viscosity in space. If the dynamic (and kinematic) viscosity characterizes the deformation of pure shear, the second viscosity characterizes the deformation of volumetric compression. The bulk viscosity plays an important role in the attenuation of sound and shock waves, and is experimentally determined by measuring the attenuation.

Project Planning Example

Project Planning Example Project Planning – Coursework Example Topic: Project PlanningName:Course:Date:Critical path in a projectBy using the knowledge of tracking the critical path in a project, the resources are always assigned to the critical tasks which are determined by the tasks that affects the project completion on a timely manner.1. These are the sequences of tasks that has no slack, and hence endorse the successiful finish date of the project. All tasks found here are fully on the critical path and therefore refered to as the project’s critical tasks.2. This is a sequence of tasks that do not drive the project’s finish date. All of this tasks are not critical.3. The total slack is the total ammount of time that this sequence of tasks can slip before affecting the finish day of the entire project.Critical tasksCritical tasks are tasks that cannot be delayed without affecting the successful finish of the project. In a project, the majority of tasks have a slack and therefore, their delay cannot delay the projects finishing date.A task becomes critical when it meets any one of the following conditions:Has got no slack. Has a Must Start on, or Must Finish On, date constraintMust have an as Late as Possible constraint in a project scheduled from a start date. Must have an As Soon As Possible constraint in project scheduling a finish date. Must have a finish date that is the same as or beyond its deadline dates. Critical risksThe project defines critical risks as those tasks that have no slacks. However you can amend when a task changes to a critical state. Slacks are determined by the early finish and the late finishing dates of the scheduled tasks. Early finish date is the most probable earliest date of task completion. ReferencesLockyer, K.

Nursing and Human Resource Sector of the Health Care Industry Assignment

Nursing and Human Resource Sector of the Health Care Industry - Assignment Example The present research has identified that there is a rising cost of providing healthcare to over 230,000 individuals, a task that is making hard for the health care system to retain and attract employers who are discouraged by the premium costs. The employers are facing the effect of having to reduce or absolutely not offering any health care benefits to the employees. The Mercy Health plans are also finding it very difficult to get a local health plan for the employers. There is also the issue of competitors who offer national health plans and worse, they have a large share of the market. As such, the mercy health plan has to strategize themselves so as to face the existing competition in the market. Among the solutions considered by the Mercy Health Plans in the face of the problem of attracting employers into their health plans, they have decided to attract employers through offering them more attractive health plans that apply to the long-term relationship they have with their emp loyee. They encourage the senior management teams of the employers to take up their health plans in order to solve this problem. This is in opposition to the selection of short-term health care plans by the senior management. This is because the short-term health plans tend to be a source of cost shifting solution to the employer and mostly offered by consumer-directed programs for health benefits. Further, the mercy health plan realizes that they have to design a health program that would cover the overall health of the entire population. This includes the consumers that do not have a high risk of healthcare complications and their probabilities of getting sick is also low. As such, it is possible that the Mercy Health plan can reduce the cost of health and attract more employers.

Discuss the role played by morality or obligation in Antigone Essay

Discuss the role played by morality or obligation in Antigone - Essay Example Creon had passed over the instructions that forbade everybody to bury the dead body of Polyneices. Creon wanted the dead body of Polyneices to rot and get eaten up by wild animals and vultures because Polyneice had died as a traitor in an attempt to attack the city. Antigone, like many people in her time, held a belief that the souls of deceased people remain restless as long as they are not buried. Not only did Antigone take a stand against Creon’s decision of leaving Polyneices’ body unburied, she actually took practical measures that prove her sincerity. However, it was not easy to go against the consent of the powerful ruler of the time. When Antigone had decided to bury her brother’s dead body, she knew she was going to risk her life and was most likely to be assassinated for her act. However, the fear of worldly punishment could not keep her from carrying out the orders of her gods. Not only did Antigone comply with the standards of morality on burying the dead body of Polyneice, but also, she would not let Ismene take the charge for having done the job because this would put Ismene into trouble. This causes the reader to draw conclusions about Antigone that she was daring, courageous, bold, prudent and considerate. She offered so much importance to her moral values that she would happily embrace death to live up to them.

France Section 1770 - 1789 - Crisis in the old regime :: European Europe History

France Section 1770 - 1789 - Crisis in the old regime The causes of tensions and conflicts generated in the old regime that contributed to the outbreak of revolution The composition of society was a major contributing factor to the tensions and conflicts generated under the old regime. Society was divided into Three Estates, the first Estate comprised of the clergy (1%), the nobility, and rest of the population was classified as the Third Estate. Not only was the Third Estate heterogeneous, comprising of the bourgeoise (lawyers, doctors, intellectuals, businessman, the traders, merchants, factory owners), peasants, and beggars, but all three Estates. Their were many distinguishing factors that set the three Estates apart. The first two Estates were associated with the monarchy and avoided or paid little taxes, whilst at the same time earning the most money. The Third Estate paid the highest taxes and earnt the least. Lefebvre saw the bourgeoisie as becoming stronger economically but still maintaining the same legal status as that of the poorest peasant. The bourgeois resented their nobles, who were simply 'born' into their position of wealth. They nobles believed that their noble birth' set them apart from the rest of society.' However, the nobility were also dissatisfied under the ancien regime, where they had little, yet still more then the bourgeois, influence in politics. Although the upper clergy enjoyed many privileges, including being exempt from paying taxes, owned about 10 per cent of the land, and received their wealth from the land they owned and the collection of the tithes. Yet, the lower clergy did not enjoy these same privileges, while the 'Bishop plays the great nobleman and spends scandalous sums on hounds, horses, furniture, servants, food and carriages, the parish priest does not have the wherewithal to buy himself a new cassock...the bishops treat their priests , not as honest footman, but as stable-boys.' It is clear that social unrest was felt by the whole population. Prior to 1780s the people of France blindly accepted the foudations of the Ancien Regime. The period known as the Enlightenment or 'Age of Reason' saw philosophes such as Voltaire and Rousseau attack the Church, and the absolute power of the King and the inequitable social composition of society. For the first time people were questioning the society in which they lived. It became the fashionable conversation of the times, and this propoganda took place in salons, cafes and even educational institutions such as the museum of Paris.

Political Justice: Plato and Aristotle Essay

Plato and Aristotle had different ideas of politics and political justice. In The Republic, Plato creates the ideal city, which is needed to guarantee justice. He aims to create a peaceful united city that will lead to the greater good of the community and individuals. Unlike Plato who imagines the ideal city, Aristotle looks at actual cities in The Politics. He doesn’t want to create the ideal city; he aims to improve the existing city. While their ideas about politics and justice were different, they both strived to find a better way of life for society and hoped to achieve political justice. In order to define justice, Socrates attempts to create an ideal city, one that is healthy and just. Socrates begins by â€Å"investigating what justice looks like in the cities† in order to â€Å"go on to consider it in individuals† (Plato, 45). He believes that it is through speech that one will see the way in which both justice and injustice come into being. Socrates argues that people come together as partners and form cities based on mutual needs because â€Å"each [person] isn’t self-sufficient but is in need of much†: food, shelter, clothing, and other necessities (Plato, 46). It is in the need that the men have of one another in a healthy city that justice can be found (Plato, 49). In the Republic, Plato argues that justice is social, structural, and peaceful. He also believes that people function best doing one thing well. According to Socrates, people naturally differ in nature; â€Å"different men are apt for the accomplishment of different jobs† (Plato, 46). Socrates argues for specialization by saying, â€Å"one man, one art† (Plato, 47). He argues that this concept of specialization is the only way to make certain that each job is done well. Socrates goes on to divide the city into three distinct classes: producers, warriors, and rulers. Socrates believes a just city requires a division of labor in order to guarantee the stability of the city and provide the common good for the citizens. He states that, â€Å"each thing becomes more plentiful, finer, and easier, when one man, exempt from other tasks, does one thing according to nature† (Plato, 47). A strict division of labor is the only way to construct a just city, in which few laws are required. Socrates uses the analogy of the healthy city to describe how â€Å"justice and injustice naturally grow in cities† (Plato, 49). A healthy city becomes an unhealthy, â€Å"feverish† city when people become driven by desire and want more than the mere necessities of a healthy city. Some people will not be satisfied with the mere necessities; thus, relishes will be added. When people desire more and more luxuries, the city must be made bigger again and again because the healthy one is no longer adequate (Plato, 50). As the city grows, more land is required in order to be sufficient. At some point, one must â€Å"cut off a piece of [their] neighbors’ land† (Plato, 50). Socrates argues that encroachment will ultimately lead to war. He goes on to state that because of thisß inevitable war, the city will require Guardians. According to Socrates, the Guardians of the state must have a very spirited soul be very well trained (Plato, 52). He goes on to argue that a good Guardian must be â€Å"a philosopher in nature, spirited, swift, and strong† (Plato, 53). They must never turn against the city and must know whom to do violence to. Therefore, â€Å"[the Guardians] must be gentle to their own and cruel to enemies† (Plato, 52). To ensure that they will never turn against the city, Socrates believes that they must be educated morally â€Å"in speech† through the stories of the Gods and heroes (Plato, 54). Socrates argues that the tales should be supervised and modified if need be, in order to instill the idea that Gods can do no wrong. Only the stories that display bravery and dispel the fear of death should be taught to the Guardians. As a citizen, a Guardian must defend their city, make war together against any enemy of the city, and fight vigilantly for one another. While Plato believed that cities and state came into being because of mutual needs and social contracts, Aristotle thought otherwise. Aristotle views the polis, or city, as a political association or partnership. Aristotle opens The Politics by saying, â€Å"every city is some sort of partnership†, which â€Å"is constituted for the sake of some good.† According to Aristotle, the city must seek to achieve â€Å"the most authoritative good of all† (Aristotle, 35). He defines villages as collections of families. These different villages come together to create a good combination of both public and private life. This is a sharp criticism of the argument Plato makes in The Republic.  Aristotle goes on to argue that a city naturally â€Å"arises from [the union of] several villages† (Aristotle, 36). In saying this, he argues that a city exists by nature (Aristotle, 37). A city forms for the purpose of living well and directs itself toward the common good. One of Aristotle’s defining arguments is that â€Å"man is by nature a political animal† (Aristotle, 37). What Aristotle is arguing is that apart from the city there is no possible way for man to achieve the good life. Aristotle claims that what makes man different from other animals are that â€Å"man alone has speech† (Aristotle, 37). It is speech that makes possible the deliberation of politics and allows man to come up with the highest authoritative good. According to Aristotle, â€Å"speech serves to reveal the advantageous and the harmful, and hence also the just and the unjust† (Aristotle, 37). In Aristotle’s city, it is speech and deliberation that justice can be found. Aristotle believes that the law developed through deliberation is â€Å"a guarantor of just things† (Aristotle, 98). In order to define what he believes to be a citizen, Aristotle first argues things that do not imply citizenship: honorary citizenship, inhabiting a place, sharing in matters of justice, children, and the elderly (Aristotle, 86). He defines citizenship as â€Å"sharing in decision and in office† (Aristotle, 87). According to Aristotle, a citizen is one who takes part in the decisions that are being made. In Aristotle’s city, the citizen is â€Å"whoever is entitled to participate† (Aristotle, 87). To him, the most important aspect of citizenship is that they are the foundation upon which the city is built. He believes that citizens have a share in the regime and should take part in administrating justice. In general, â€Å"a citizen is defined as a person from parents who are both citizens† (Aristotle, 88). Aristotle believes that as constitutions change, citizenship changes as well. Thus, there is different criterion for being a good citizen and being a good man. According to Aristotle, a good citizen upholds and respects the constitution. He claims, â€Å"a good citizen should know and have the capacity both to be ruled and to rule† (Aristotle, 92). In the Republic, Socrates gives three waves that he believes are necessary to  achieve justice in an unhealthy city. The first wave states that there should be equality among men and women of the Guardian class. He writes that men and women of the Guardian class are to share â€Å"everything in common† (Plato, 130). This wave not only deals with equality, it also deals with merit. Despite the fact that men are typically stronger than women, women should be nurtured in the same way as men and educated in the same things. Even though it may seem â€Å"shameful and ridiculous†, women are to be trained in gymnastics together with men (Plato, 130). After establishing the need for equality among men and women, Socrates moves on to the second wave. The second wave, Socrates argues, is that women and children need to be held in common. He believes that â€Å"women are to belong to men in common† and that â€Å"no woman can live privately with any man† (Plato, 136). Socrates is trying to rid the unhealthy city of private life because he believes that justice is social. The Guardians must live as one single family in order to reduce factional conflict. In order for the Guardians to live as one single family, Socrates argues that not only are men and women to be held in common, their children are to be held in common as well. â€Å"A parent will neither know his own offspring, nor a child his parent† (Plato, 136). The goal of this is to, again, rid them of the jealousies and rivalries that accompany private families. Socrates believes that this will make certain greater social equality and increase the unity among the Guardian class. Because the Guardians share everything in common, there will no longer be any concept of private ownership. Thus, there will be harmony and unity within the city. The third, and final, wave Socrates discuses details who it is that he believes should rule in a just city. The third and final wave that Socrates believes is necessary for justice is that philosophers must be the rulers. After making this argument, Glaucon demands that Socrates defines what he means as a philosopher. Socrates believes that â€Å"the philosopher is a desirer of wisdom, not of one part and not another, but of all of it† (Plato, 155). The philosopher is a lover of wisdom and total knowledge. Because of this, Socrates argues that philosophers are the only people capable of having knowledge of everything all together; they are open-minded and constantly curious. To further his  argument about the philosopher, Socrates states that the philosopher is a lover of the truth; he has knowledge of what is real instead of simply believing in appearances. The first proposal that Socrates makes in The Republic makes sense to me. There should be equality among men and women, but they do not need to share everything is common. There needs to be a balance of both public and private life. It would not make sense to rid society of private life entirely. The second proposal that Socrates makes does not make much sense at all; it would not work if we wanted to enact a similar system in today’s society. It is not logical to think that children would be better people and that society would be a better place if children were taken from their mothers at birth and raised by wet nurses. People need the bond of a private family, it is from family that children learn to love and be loved. The philosophers-as-rulers proposal that Socrates discusses makes sense but it seems extremely unrealistic. A philosopher is the last person that would want to rule a city. Overall, these proposals would every facet of a city. The proposals that he makes are intended to be extreme and ironic. Plato is trying to push his readers in absurd directions in order to establish that justice will never be found. The healthy city in Plato’s The Republic gives the best definition of justice. The whole intention of creating this ideal city is to define what justice is. Essentially, in his ideal city, there is no injustice. Because Plato uses his ideal state to show how justice and injustice naturally arise in cities, it is much easier to grasp what justice is and how it comes into being. Because Plato creates the perfect government, he is able to give a clear definition of what justice is. Aristotle’s definition of distributive justice: giving equal things to equal people and unequal things to unequal people can be confusing. While the healthy city may give the best definition of justice, it does not provide the best model for politics. Though it may not be ideal, Aristotle’s ideal city provides the best model for politics. In Aristotle’s view politics is only a means to an end; that end being the maximum happiness of its citizens. Unlike Plato, who places the burden of  ruling solely in the Guardian class, Aristotle believes that everyone should take turn ruling and being ruled (Aristotle, 219). Aristotle argues that the purpose of politics and that city is to promote the good life for its people. He believes that the citizens of a state should agree about what is right and wrong, just and unjust. Plato believes that philosophers are the only people capable of knowing the truth. Aristotle gives a better argument that everyone is capable of knowing the truth. He believes that politics is responsible for educating men in what is right and wrong. Just as Aristotle argues, written law should have greater authority than the rulers. Thus, leading to justice. Both Plato and Aristotle make good arguments about political justice even though the two do not completely agree. By creating an ideal city, Plato clearly defines what justice is. On the other hand, by looking at existing cities, Aristotle gives a good model for politics. While their ideas about politics and justice were different, they both strived to find a better way of life for society and hoped to achieve political justice. Bibliography Aristotle, The Politics.
