Simulation of IV Bag Decanting

Simulation of IV Bag Decanting Base Design and Equations The setup of the simulation is given below. The point at the top of the fluid in the IV bag is denoted with a subscript 1. The point at the exit of the catheter into the patient’s arm is denoted with a subscript 2. Assuming that the patient does not move his/her arm during the procedure, we can set point 2 as a static, whereas point 1 is moving dynamically as the bag empties. Bernoulli’s Equation in the units of energy is given as: Setting point 2 as the height of ground, excluding the pumping term and combining pressure terms into a pressure difference, but measuring PÂ ­1 and P2 in gauge pressure and assuming P1 to be atmospheric yields the following equation: Where Where For laminar flow (Re And for turbulent (Re > 2100): Mathematical Development Derivation of equations pertaining to the IV bag What is needed first is a way to find the volume of fluid still within the bag when only knowing the height of the fluid in the bag. Taking the central axis of the bag as an independent variable and viewing the radius of the bag at that point as a dependent variable yields the following straight line: Which has the equation: And performing a solid of revolution about the h axis: It is know that and that by mass balance assuming no accumulation in the pipe But: Finally for the frustum IV bag: Friction terms development Comparing the Reynold’s number in the pipe and the catheter: But by mass balance and assuming no accumulation: Which is always less than one. Therefore if flow in the catheter is laminar, then flow in the pipe has to be laminar too. This leaves 3 cases of flow in the system. The first is flow is laminar in the catheter and pipe. The second case is flow is turbulent in the catheter, but laminar in the pipe, or flow is turbulent for the catheter and pipe. For the first case where flow is laminar in both the catheter and the pipe: If the flow is turbulent in the catheter, then the friction term is the sum of the friction from the pipe and the catheter: Simulation Program Development Solving velocity of fluid leaving the catheter for any fluid height h The above Equations 1-9 are easily incorporated into matlab functions (Appendix A: Calculations functions). The first problem that the program must solve is calculating the instantaneous velocity of fluid out of the catheter at any height of fluid in the IV bag. First the flow in the catheter is assumed to be laminar (this is just a starting point for iterations). The correct velocity of the fluid leaving the catheter is the point here Equation 1 is stable. Since the equation contains a square root, for the answer to be reasonable then there has to be a positive root. i.e: Substituting equations 3 and 5 Since is very small, it’s square may be neglected (checked with given simulation values it was on the order of 10-10) The velocity that satisfies the stable solution of Equation 10 must therefore lie between 0 and for laminar flow speeds. This means that Equation 10 may be solved by bisection method, giving the instantaneous velocity out of the catheter for a certain height of fluid in the IV bag. If the maximum and minimum velocities do not generate the proper conditions required for the bisection method (one function value must produce a number greater than zero, and the other must generate a number below zero to imply a root between the two numbers on a continuous function), then the flow velocity must be such that the flow is turbulent in the catheter. If it is the case that flow must be turbulent in the catheter, then we can set an initial guess of v2 at the minimum velocity required to have turbulent flow in the catheter. Using this as an initial velocity, it can be iterated until a stable solution is found. See Appendix B for this programming logic. Comments have been added to aid understanding. Fluid flow out of the IV bag In order to calculate how fluid flows out of the IV bag, we set the program to take small time elements and determine the velocity of the fluid flowing out of the catheter for a set fluid height. Since that time element is small, we assumed that the velocity did not change appreciably in that small element. Volumetric flow is the product of linear velocity of flow and cross-sectional surface area, and assuming no accumulation in the pipe for mass balance: Now we need to know what the height is of the bag for that volume, which is simply the real root that solves Equation 2. This entire process is iterated for each time element until the bag empties or the fluid velocity leaving the catheter is zero. This logic may be found in Appendix C. Concatenating Results Finally a matrix is constructed that holds all data of the catheter fluid velocity, bag volume, fluid flow rate and height of fluid in the bag and is concatenated with a time vector. This resultant matrix now holds all of the data of the simulation, which is parsed to the primary class that is running the simulation to produce the graphs, and find numerical values for points on the graphs. Results of Simulation The following data was fed into matlab: P2 = 90.228/760*101325; Lcat = 43.703/1000; Dcat = 0.711/1000; Lpipe = 1.383; H = 22.8/100; R = 0.3829*H; hd = 1.377; Dpipe = 3/1000; rpipe = 0.5*Dpipe; mu = 1.142/1000; rho = 1017; X = calcX(R,H,rpipe); h0 = 0.8*X; beta = (R-rpipe)/X; The simulation was run using the following command to retrieve the results matrix: VhvQt = generateVhvtQMatrix(rho,Dcat,mu,Lpipe,Lcat,Dpipe,beta,h0,rpipe,9.81,hd,P2); Solution graphs were plotted as follows: plot(VhvQt(5,:),VhvQt(2,:)); xlabel(Time in seconds); ylabel(Height of fluid in bag in meters); Bag volume is row 1, height of bag is row 2, velocity of fluid in the catheter is row 3, flowrate is row 4 and row 5 is the time vector. To find the total time taken for the bag to empty, the command was used: VhvQt(5,end) = 3122 Similar commands were used to find exact datapoints at any period in time. Discussion of Simulation Results The values of the viscosity and density of the 5% w/v glucose solution – more commonly known as D5W, Dextrose 5 Water or Intravenous Sugar Solution, were looked up from Wolfram Alpha’s material database, and had the values of and . (Wolfram Alpha) The purpose of the simulation was to calculate and plot the graphs as well as answer how long it takes for the bag to drain. It took 3122 seconds for the bag to drain, or just over 52 minutes. At the last second of the simulation, the height of fluid in the bag was less than 4 millimetres, which corresponds to a volume of 0.045 mL. Figures 3-5 all show a negative exponential function, which is to be expected since the flow rate is a function of the head pressure, which is a function of the conical shape of the bag. Initially, the high flow rate that corresponds with the higher head of fluid does not change very much, as the level of fluid in the cone does not drop significantly quickly. However, after about 2500 seconds (80% through the time of the simulation), the velocity of fluid leaving the catheter begins to change. While this change is clearly not linear, it is not really significant when compared to the absolute changes in values. From the start of the simulation until 80% through the simulation (2500 seconds), the velocity of fluid in the catheter only changes from 0.8655 to 0.6922 m/s, or 20.02%. It is only in the last period of time just before the bag empties is there a significant change in the velocity of fluid entering the patient, with the final velocity being 0.4707 m/s just as the bag empties, which is itself only a change of 45.62%. This phenomenon is most apparent in Figure 6, where it can be seen that the volume of fluid left in the bag appears to decant at an almost linear rate (differential of volume/time is flow rate). Only just after 2500 seconds does the steepness of the graph very slightly begin to change upward indicated a slow in the flow rate of fluid leaving the bag. This phenomenon does, however, make sense. The height that the bag is lifted above the catheter is hd = 1.377 meters. The height of fluid in the bag at the start of the procedure is h0 = 0.1793m, or only 13.20% of hd. The means that the driving force behind the IV procedure (which is the height above the IV bag is placed above the catheter in the patient’s arm) that creates the pressure difference to overcome the venous pressure of blood in the patient’s veins only changes by 13.2%, and remains changed by only 20.02 % during the initial 80% of the procedure – in other words, it doesn’t change by much, and therefore we expect that the flow rate won’t change very much until very close to the end of the procedure, which is what we see in Figure 3. In real world application, this means that in general the flow rate of IV solution to the patient is mostly a function of how high above the patient the IV bag is placed, and not necessarily how empty or full the bag its self is. In fact, general practise used by doctors is simply to place the IV bag above the heart level of the patient (Dr. Chen-Maynard, 1999). In application, a desired flow rate of IV fluid into the patient may controlled by lowering or lifting the IV bag a certain height above the patient. Nomenclature References Dr. Chen-Maynard, P. R.

Scarlet Letter Symbols :: essays research papers

Nathaniel Hawthorne uses many symbols to add meaning to his novel, The Scarlet Letter. This novel was written in 1850 by Nathaniel Hawthorne. This novel is classified as a romance due to the events that happen through out the book. The book takes place in 1640's Boston. Nathaniel Hawthorne uses many symbols to give the book strength and power over the reader. Two symbols that Hawthorne uses are the rosebush, and Pearl. These two symbols help in the revelation of the story, from beginning to end. Hester is kept in the prison due to her sin of adultery that she has committed. As she walks herself from the prison doors to the scaffold, the readers become acquainted with the rose-bush . This rose bush is said to be kept alive with history. Hawthorne says how he plucks one of the rose-bush flowers and presents it to the reader. "It may serve, let us hope, to symbolize some sweet moral blossom, that may be found along the track, or relieve the darkening close tale of human frailty and sorrow." (p. 46) When Hawthorne shows the reader the rose bloom, he point out that beauty comes with a price, but also it is next to the prison door. The rose-bush symbolizes the pain and joy that come through Hester's sin. One of the most painful yet most important thing to Hester is Pearl. Pearl is also a very important symbol though the story. She is Hester's pride and joy that leads her through the day., but also her full time reminder of the sin she has committed. "Therefore it is good for this poor, sinful woman that she hath an infant immortality, a being capable of eternal joy or sorrow, confided to her care,-to at ever moment, of her fall,-but yet to teach her, as it were by the Creator's sacred pledge, that if she bring the child to heaven, that child will also bring the parent thither!"(p.105) Here Mr. Dimmesdale explains how Pearl, is the eternal joy and sorrow of Hester's life. Also how Pearl can save her mothers soul, if Hester can save Pearl's first. Hawthorne says at the end of the story that Pearl grew up and took her mother's sin into consideration in her life, and grew up to have a happy family.

Gay, Lesbian and Bisexual Issues - AIDS, Isn’t it Time We Demand Action? :: Argumentative Persuasive Essays

AIDS – Isn’t it Time We Demand Action? There are 42 million people living with AIDS worldwide. 950,000 are in the United States. New cases exceed 5 million every year. More than 28 million people die from AIDS each year. Within 10 years there will be 40 million orphans in Africa due to AIDS, and more than one-third of heavily affected countries have no strategies to deal with them. AIDS is now the fourth leading cause of death globally, and the leading cause of death in Africa (â€Å"AIDS at 20†). The plague that’s killed 22 million isn’t done with us yet. While we hunt for a vaccine, people continue to die—from AIDS or the drugs intended to treat it (â€Å"AIDS at 20†). â€Å"AIDS is not only killing the sick, but also crushing the healthy. There are two kinds of people here, the infected and the affected† (Kristof, â€Å"As Millions Die†). Though there are various excuses regarding AIDS funding, political stances, and the debate of whether or not Africa is ready to receive treatment, the fact remains that AIDS cannot sit on the backburner anymore: action needs to be taken now. FUNDING First, the question of funding; the cost of drugs has been a major issue in the treatment of AIDS. The estimated spending on AIDS prevention, care, and support in low and middle income countries in 2003 is $4.7 billion, while the estimated dollars needed to address AIDS care, prevention and support in low and middle income countries is $6.5 billion in 2003 alone, with an additional $10.5 billion in 2005 and $15 billion in 2007 (Avert). In part because of those inadequate funds, many countries will not meet basic goals like rapidly expanding AIDS prevention and care expected to them by 2005. Perhaps if America wasn’t spending an extra 87 billion dollars on futile efforts in Iraq, they would have more money to spend on the dying. â€Å"If pockets had been opened earlier, millions of lives would have been saved† (â€Å"Slowly, the Virus is Being Fought†). POLITICS There are also many various political stances regarding AIDS; President Bush pledged $15 billion for AIDS in African countries and the Caribbean over the next five years. But instead of $3 billion for the first year, he backtracked to just $2 billion (Kristof, â€Å"Prudery†). And instead of using existing channels to help, Bush created a new bureaucracy.

Oedipus Tyrannus through Freuds eyes Essay

Oedipus Tyrannus is deemed as Sophocles’s magnum opus and is undoubtedly the most famous of all Greek tragedies. Aristotle went to the extent of calling it a perfect play. It was first performed in around 425 b. c. , only just after a plague that had wreaked havoc on Athens, Oedipus Tyrannus was set in Thebes, a city which was also facing the same catastrophe. King Oedipus was informed by the Creon, the brother of Oedipus’s wife, Jocasta that the city will remain a sufferer unless and until the slayer of the previous king is convicted. Oedipus promised to discover the killer’s identity and to prosecute him. Ignorant of the fact that he himself was the murderer, Oedipus unremittingly trailed the truth until he found his own guiltiness and blinded himself so he might never catch the sight of his father in the afterworld. A Freudian analysis of Sophocles’ Oedipus Rex (the King) would point out that Oedipus truly had an incestuous nature. This was exposed not only by Oedipus’ marriage to his own mother, by whom he had children, but also by his unreasonable preference for his daughters, Antigone and Ismene. While the attention he showed to his daughters was profound and braced with sexuality, he dismissed his sons as creatures who are able to look after themselves. Although he was unconsciously attracted to his daughters, he also had this fear in his mind that his daughters would become pariah and will be unable to marry. Freud thought that all the men since birth harbor not a natural repugnance to incest, but the contrary which is an instinctive sexual attraction to the mother. He says, â€Å"[The experiences of psychoanalysis] have taught . . that the first sexual impulses of the young are regularly of an incestuous nature† (Totem and Taboo, p. 160). He also emphasized that each male anchorage undecided feelings towards their fathers. â€Å"But surely I must fear my mother’s bed? † (Oedipus Tyrannus, line 576) When Oedipus throws this question to his wife Jocasta, he is totally oblivious of the profundity of his words. The Messenger has just informed him about the murder of King Polybos of Corinth, Oedipus’ supposed father. Now free in his mind from the intimidation of Apollo’s foretell that he would kill his father, Oedipus here desires to validate with his wife that, as his hypothetical mother (the queen of Corinth) is still living, he must still look into that for fear that he sleep with her, as the oracle also foretold. But his words touch a more primary issue: Why is the forecast that he will sleep with his mother so horribly threatening and vile? Oedipus is actually calmed and contented about the natural death of his supposed father Polybos, as in his mind this frees him from the concern that he will someday kill his father. Freud had suggested an interesting explanation of the source of the taboos against incest and parent murder. In the primitive civilization, people lived in groups dominated by the most powerful male, the father, who hold a sexual monopoly over the group. When each of his sons grew to an age where he would challenge the father’s supremacy in order to get a part of the action, so to challenge, the fathers forced them to leave the group. After so many sons had been so treated like this, they resolute to cooperate in order to remove from power their father and get hold of the females, their mothers, for themselves. With their collective strength, they killed the fathers. In civilized society, Freud observed, proscription against such crimes go unsaid, but this is not evidence that we no longer harbor such wishes. The conscience of mankind which now appears as an inherited mental force was acquired in connection with the Oedipus complex. However, from Sophocles’ text, it would seem that Oedipus does everything in his power to avert these two crimes. Freud too examines the play from this vantage point although, under the novel concept of unconscious motivation, moral condemnation gives way. Freud’s perspective added another dimension to previous simplistic disputes as to whether an action was freely willed, and thus subject to moral injunction, or determined by fate. Freudian intentionality implied that there were actions which, though not intended (consciously), nevertheless were compulsive enactments of inner latent wishes (Hamilton 1993, p. 209).

In View of Traditional and Modern Ethics Essay

IntroductionThe study of philosophy has long been a part of our society. The region of moral philosophy is one of the important branches of philosophy. morals deals intimately moral values our apprehensiveness of what is right or wrong, about animateness, about ones rights and regarding the Divine being. What we be now is the product of the past. Ethics barf our personality. It is how we live our lives. Ethics guides us in seeking the answers to the many different queries we allow in mind like wherefore we exist, wherefore we long for true happiness, and why cant we avoid libertine acts.Traditional vs. Modern EthicsThe counsel of tralatitious ethical motive differs from the youthful morals in many ways. Traditional moral philosophy goes back during the multiplication of Plato, Aristotle, and Socrates in the quaint times. These ideas of conventional ethical motive have plough the basis of succeeding ethics foundations. The ethics being promoted today has already existed before. The valet de chambre has changed. People have also changed. Thus, ethics change to adapt to the changes in the initiation and the peoples perspective.Ethical and policy-making philosophy awakening started as earlier as 5th century B.C. in Greece by the Sophist. They desired to discover the warmness of moral virtues, the form of good which is the supreme source of reality and value.There be a number of themes or doctrines that emerged. These atomic number 18 skepticism, relativism, subjectivism, egoism, and hedonism. Some ethical egoists suggested that ones highest objective is to lead a winning life focusing on his or her pleasures. It gave birth to Epicureanism and Stoicism.During the medieval times the Christianization of ethics took place with the coming of St. Augustine, St. Hildegard, and St. doubting Thomas Aquinas. later on on utilitarianism emerged and also philosophers like Thomas Hobbes, Immanuel Kant, and John Stuart Mill.Around 18th and ninetee nth centuries moral philosophy focused on politics. People were also exposed to Liberalism, Marxism, Communism, and Anarchism. new-fangled moral and political philosophers introduce the concept of normative ethics, emotivist, invisible hand mechanism, conservatism, socialism, and egalitarian socialism to name a few. Philosophers complicate G.E. Moore, W.D. Ross, John Rowls and other important names. windup clean issues are important invade for all people not average for the philosophers. All the philosophers from the ancient to the modern times have contributed to our own system of beliefs regarding life and the many issues of human existence. Indeed traditional and modern ethics are link and supportive of each other. Ideas of the traditional ethics are the foundation of the modern ethics. Advocates of modern ethics customized or revised the concepts of the traditional ethics to fit todays society. Both traditional and modern ethics have influenced the way people debate and analyze life and their society.ReferenceMoore-Bruder, (2005). Moral and Political Philosophy.

Controlling Inflation

INTRODUCTION Of the various ills the frugality basin face, swelling is simultaneously the whisk for society as a whole. rising expenditures can be defined as the direct at which the general take aim of prices for superbs and serve is rising, and, sequently, purchase power is dropping (investopedia. com). pompousness is a sustained increment in the general direct of prices. Since lump is have-to doe with with increments in the general level of prices, changes in the price of a adept good or service cannot be characterized as pretension.The puffiness position is unremarkably posterd by percentage changes in the damage of a basket of consumer goods and ope wander ( fundamental cuss). fanfare in Trinidad has been fluctuating, as utter in the article puffiness rears to 5 per cent, found in the Saturday Guardian on the 27th February, 2010. The article gave the information prone in the report done by the Central Statistical Office it express that headline lum p go up by 3. 7 per cent in the 12 calendar months to January 2010 from the 1. 3 per cent a month earlier. Food price swelling rose by 2. per cent on a year on year earth in January fol broken ining a aggravate of 0. 2 per cent in declination 2009. totality inflation which excludes the impact of nourishment prices, rose to 4. 2 per cent (year on year) in January from 2. 2 per cent in celestial latitude. On a monthly basis, center field inflation rose by 2. 2 per cent in January 2010, following an maturation of 0. 1 per cent in December 2009 and three consecutive monthly declines. So we clearly see that inflation is bear witness in the economy, and from the article it is rather unpredictable. What we hire to ask ourselves is how we can continue with inflation?What we can do to make inflation easier? What can the governance do what give the Central hope do to deal with inflation? THE QUESTION INFLATION IS ON THE RISE, SO WHAT CAN BE through BY THE CENTRAL BANK OF TRINI DAD AND TOBAGO TO manoeuvre INFLATION? LIMITATIONS/ CHALLENGES -My introductory challenge was that it was quite difficult to find an article that was appropriate, and dealt with the topics beingness covered this semester. -It was alike a fighting difficult to make sense of the article, and then(prenominal) to find literature to support it. literature was found but making the affair was quite difficult. LITERATURE REVIEW Austrian economists maintain that inflation is by rendering al expressive styles and everyplace simply an summation in the coin supply (i. e. units of specie or means of shift), which in resign leads to a higher nominal price level for assets (such as housing) and other(a) goods and services in rent, as the truly lever of each pecuniary unit is eroded, loses purchasing power and thus buys fewer goods and services.Ludwig von Mises (cited in Wikiedia, 2010), the seminal scholar of the Austrian School, asserts that Inflation, as this condition was alw ays employ everywhere and especially in this country, means increase the quantity of funds and depone notes in circulation and the quantity of bank deposits subject to check. save people today use the term inflation to refer to the phenomenon that is an undeniable consequence of inflation, that is the object of all prices and wage rates to rise. The depart of this deplorable mix-up is that there is no term left to signify the attain of this rise in prices and wages.There is no longer any word addressable to signify the phenomenon that has been, up to now, called inflation. . . . As you cannot talking to about something that has no name, you cannot fight it. Those who behave to fight inflation are in fact only fighting what is the inevitable consequence of inflation, rising prices. Their ventures are blame to bereavement because they do not tone-beginning the root of the evil. They try to keep prices low while firmly committed to a insurance of increasing the quantity of coin that must necessarily make them soar.As long as this terminological confusion is not entirely wiped out, there cannot be any question of stopping inflation. Inflation is always and everywhere a pecuniary phenomenon. Milton Friedman, (1963). Friedman maintained that there is a occlude and still association between inflation and the cash supply mainly that the phenomenon of inflation is to be regulated by controlling the amount of bills put into the home(a) economy by the Federal arriere pensee Bank. Friedman rejected the use of fiscal insurance as a tool of demand management and he held that the administrations role in the guidance of the economy should be dependant severely.Friedman wrote extensively on the Great Depression, which he termed the Great Contraction, arguing that it had been caused by an middling financial shock whose duration and serious-mindedness were greatly increased by the subsequent contraction of the coin supply caused by the misguided p olicies of the directors of the Federal Reserve. Inflation and fiscal polity are closely tie in concepts wherein the latter can be used efficiently to crop the effect of the former. Inflation is thought of as the rise in prices and wages that reduces the purchasing power of money. monetary insurance is the regulation adopted by the central bank, currency board or other restrainive authority which perk ups the prices and maximizes outturn and employment of the country. Inflation is characterized by an increase in the general level of prices for goods and services. As a consequence, the purchasing power of money get out fall. Most of the countries in the innovation try to sustain an inflation rate between 2 and 3 percent. The Fishers equation depicts that proportional relation that exists between money supply and the price level. monetary polity is a regulation of a central bank or any regulatory authority, which as certains the size and growth rate of the money supply. fiscal policy directly makes the kindle rates which in turn has a negative relation with the price level. In the face of inflation the central bank of the country generally resorts to a rise in the cash reserve ratio, repo rate and reverse repo rate. So the basic conceit is to reduce the money supply in the economy. To this end governance securities are also issued so as to mop up the excess money supply from the mass. This would reduce aggregate demand.This reduction would again encourage reduce the price level. financial policy is adopted with an objective to make the nearly of production and employment and consequently stabilize the price level of a country. Monetary policy also regulates the interest rate, accessibility of credit and at the same fourth dimension promotes the boilersuit economic growth of a country. Monetary policy facilitates establishing trade relationships with other countries. The Central Bank conducts monetary policy with the objective of maintain ing a low and stable rate of inflation, an separately immaterial exchange market and an adequate level of foreign exchange reserves.The conduct of monetary policy is influenced significantly by the pace of real economic activity, the fiscal operations of the government, metropolis flows and the operations of the commercial banks. In order to achieve the goals of monetary policy, the Central Banks actions are designed to influence the level of liquidity in the banking system, which indirectly affects the level of interest rates and, ultimately, the overall demand for goods and services in the economy.The Monetary polity Committee comprising the Governor and lieutenant Governor deals with monetary policy matters including the backdrop of the repo rate which is announced on the first Thursday of each month. The Monetary form _or_ system of government Support Committee, which is chaired by the Deputy Governor, look into and Policy, and includes senior staff of the Research, Domes tic commercialize and Financial Institutions Supervision Departments, bids advice to the Monetary Policy Committee. This information was taken from the central bank of Trinidad and Tobago website.Governments have different areas of policy which they can use to regulate the economy. Here we will look at how they affect inflation. wizard policy is fiscal policy. fiscal policy is based upon demand management, i. e. raising or lowering the level of aggregate demand. The or so obvious policy is that governments should reduce government expenditure and raise taxes. It should be tell here that this policy will be successful only against demand inflation. Fiscal policy was the chief counter- inflationary measure in the 1950s and 1960s.One of the reasons for its failure then was the clash of objectives. Another policy is monetary policy. For many years monetary policy was seen as only secondary to fiscal policy. The Radcliffe reports conclusion, that money is not important, was widened into money does not matter. If m0onetary policy had a role, Keynesians sawing machine it as being through the rate of interest. The monetarist prescription is to control the supply of money. This, as we have seen, was believed to be the only way in which inflation could be controlled. because there is the direct intervention prices and income policy.A price and income policy is where the government takes measures to restrict the increase in wages (income) and prices. (Beardshaw, Brewster, Cormack and Ross. 2001, p. 559-62). gloss OF TERMS CORE INFLATION- The component of thrifty inflation that has no medium to semipermanent impact on real output. It is ordinarily derived by omitting volatile changes in the prices of certain items such as food and energy. monetary POLICY- refers to the expenditure a government undertakes to provide goods and services and to the way in which the government finances these expenditures.HEADLINE INFLATION- Inflation, as careful by the change in the overall retail prices index, is sometimes called headline inflation. INFLATION- Inflation is a sustained increase in the general level of prices. Since inflation is concerned with increases in the general level of prices, changes in the price of a single good or service cannot be characterized as inflation. The inflation rate is normally calculated by percentage changes in the cost of a basket of consumer goods and services.LIQUIDITY- The level of cash or near cash assets of financial institutions readily available to meet day-by-day transaction needs. REPO RATE- Discount rate at which a central bank repurchases government securities from the commercial banks, depending on the level of money supply it decides to maintain in the countrys monetary system.
