A personality review of Dr. Maya Angelou (personality...

Dr. Maya Angelou was born Marguerite Johnson on April 4, 1928, in St. Louis, Missouri. Her father, Baily Johnson, was a doorman, and, later a dietician for the navy. Her mother, Vivian Johnson, was a registered nurse. When Angelou was three years old, her parents were divorced. They sent her and her four-year-old brother, Baily, Jr., to live with their paternal grandmother, Annie Henderson, in Stamps, Arkansas. Henderson ran a small general store and managed to scrape by. She continued to do so after her grandchildren joined her. Angelous grandmother was one the many strong who trained her, helped her, and provided her with role models. The people of her church also nurtured her and gave her a sense of belonging to a community. But her†¦show more content†¦The four other volumes of her autobiography are, Gather Together in My Name (1974), Singin and Swingin and Gettin Merry Like Christmas (1976), The Heart of a woman (1981), and All Gods Children Need Travelin Shoes (1986). She also published several volumes of poetry and has been nominated for the Pulitzer Prize for one of the, Just Give Me a Cool Drink of Water fore I Diiie (1971). In 1973, Angelou appeared on Broadway in Look Away and was nominated for a Tony Award. In 1977 she received an Emmy nomination for her performance in the mini series Roots. She was appointed to the Bicentennial Commission by President Gerald Ford and to the Commission of International Womens Year by President Jimmy Carter. For many Americans, one of the most memorable moments during the inauguration of President Bill Clinton, on January 20, 1993, came when Maya Angelou recited the poem, On the Pulse of Morning not since 1961, when Robert Frost read his work at the ceremony for president John F. Kennedy, had a poet taken part in a presidential inauguration. Dr. Angelou is best known for the first volume of her autobiography, in it, she bravely speaks of her battle to overcome abuse, rape, and poverty. For thousands of young Black women reading the book, it is a way of passage for those who have been similarly victimized, it is like a soothing ointment that helps heal the wounds. Angelou gives a voice to the voiceless; she says, Youre not alone.

An Overview Of Phytoremediation Environmental Sciences Essay Free Essays

string(58) " the action of both phytosiderophores and phytochelatins\." Phytoremediation is a set of inactive engineerings utilizing green workss to take pollutants from the environment largely dirt and land H2O, devouring merely solar-energy. Unique biological mechanisms in workss like their ability to uptake and hive away toxic contaminations, change overing toxic contaminations to less risky substances and the symbiotic association of workss with bugs in their rhizosphere are studied and applied harmonizing to the status of the site to be remediated. Plants are used in such a manner that environmental toxins are removed, degraded or immobilized resulting in healthy country sites for better and more good usage. We will write a custom essay sample on An Overview Of Phytoremediation Environmental Sciences Essay or any similar topic only for you Order Now Proper pick of workss is made. If all of import factors sing the remediative action of workss are kept in head so the debasement or remotion of harmful chemicals from dirt and H2O can be accelerated utilizing any suited method of Phytoremediation. Phytoremediation has ever been an underrated engineering and much attending was n’t given to it until really late when successful efforts of taking heavy metals ; like arsenous anhydride, nickel, crude oil hydrocarbons, pesticides and other toxic chemicals from dirt and land H2O were reported with the usage of workss. Phytoremediation is the usage of workss to take pollutants from the environment or to covert them to less harmful compounds ( Gleba et al, 1999 ) . Plants are used in such a manner that environmental toxins are removed, degraded or immobilized resulting in healthy country sites for better and more good usage. Combinations of different engineerings are applied for efficiency but the focal point ever remains on speed uping debasement of organic contaminations and on remotion of risky heavy metals in dirt or H2O. The metals targeted in Phytoremediation include lead, Cd, Cr, arsenic and radionuclides ( Raskin et al, 1997 ) . In Phytoremediation the demand to dispose off the transformed stuff to some topographic point else is excavated therefore doing the procedure easier. Phytoremediation can be done at the really site of taint known as in-situ like near the surface soils or in the deep aquifer. The option is that dirt or H2O samples from the country to be treated can be separated and Ph ytoremediation can be applied on them, this is known as ex-situ. Examples of the latter one include extracted ground H2O or surface H2O ( Agarwal, 2005 ) . Now scientists are taking acute involvement in Phytoremediation and to convey in limelight more about this works genetic sciences are besides being taken into history. There is no uncertainty that in approaching old ages Phytoremediation will go one of the most of import of all green engineerings. MECHANISMS OF PHYTOREMEDIATION Plants carry out Phytoremediation due the many interesting and utile belongingss that they have like the capableness to pull out and concentrate assorted compounds from the environment. Others use the micro-organisms nowadays in Rhizosphere ; zone around the root, to transport out phytoremediative action. Microbial Activity in the root country: Microbes which can take phytoremediative action are present in the rhizosphere. These include both bacteriums and Fungis which make a symbiotic relationship with workss. This mechanism of Phytoremediation is termed as Phytostimulation. Plants secrete particular bio-enhancing compounds into the dirt which stimulate the bioactivity of bugs. These exudations are really a beginning of C and N because they largely include Amino acids, saccharides, polyoses, phenols and flavinoids. They support the growing of bugs that degrade toxic compounds. Root systems besides provide a high O content which enables bugs to boom easy. Fungi and other groups of bugs release extracellular enzymes which besides aid the procedure as Rhizosphere microbic debasement. Pure civilizations of Pseudomonas fluorscens and Chyrsobacterium indologenes found in rhizosphere can degrade mefenoxan, a antifungal to free acid in approx. 54 hours ( Pai et al, 2001 ) . The efficiency of rhizosphere debasement by bugs depends upon the species of workss involved because every works interacts with bugs in its ain manner ( Shaan and Boyle, 1994 ) . Root exudate straight effects the action of bugs on contaminations. If contaminations are ab/adsorbed or uptaken by works roots more, their bioavailability to microbic community lessenings. Wetting agents if added ; increase bioavailability of contaminations to microbes. Alfalfa works was studied in four different control groups: Planted diesel-contaminated and uncontaminated dirt, and Un-planted Diesel contaminated and uncontaminated dirt ( Kim et al, 2006 ) . After a stabilisation clip of 7 hebdomads the remotion efficiency was seen to be 82.5 % in deep-rooted diesel-contaminated pot while in bulk dirt of remainder of the controls it was approx. 59.4 % . Microbial activity additions in contaminated dirt as many dirt bacteriums and hydrocarbon debasers are able to boom. Microbial population is greatly affected by the conta minant itself as compared to the works roots, because the contamination is a nutrient beginning for the bugs. 2. Hyperaccumulation of heavy metals: Some workss take remove toxins expecially heavy metals and metalloids etc from dirt and H2O by uptaking and hive awaying them as in Phytoextraction. This works tissue can be harvested and treated subsequently on by ashing, smelting, drying or composting ( Raskin et al, 1997 ) . Metallic elements can even be recovered from the ash which reduces risky waste and besides gives us a metal resource that can be expeditiously used. Many hyperaccumulating workss frequently do non take up every bit much of the contamination as they can because it is extremely sorbed on the dirt so is non bioavailable to the works root. For illustration Brassica juncea has the familial capableness to roll up lead but it still does non get much lead into its biomass when grown in contaminated dirt. Application of chelating agents like EDTA a few yearss before crop can cut down this job of missing bioavailability. Iron-Chelating compounds like Phytosiderophores can be applied to dirty which can mobilise Cu, Zn and Mn every bit good ( Raskin et al, 1997 ) . Phytochelatins have been observed as efficient chelators of As in Holcus lanatus ( Raab et al, 2004 ) . Biostimulants can merely be added to dirty because they perform the action of both phytosiderophores and phytochelatins. You read "An Overview Of Phytoremediation Environmental Sciences Essay" in category "Essay examples" These include humic substances, lactic acid oligomers ( K innersley, 1992 ) , reductases released from works roots ( Welch et al, 1992 ) and dirt souring protons ( Crowley et al, 1991 ) . Once the metal has been solubilized it is taken up by the roots. Plants have constitutional transporter systems for the ions that it has to take up like sultr 1 ; 2 sulfate transporter for Se or selenate ion. Nonspecific metal ion bearers and channels are present ( Clarkson and Luttge, 1989 ) and the of course needed ions and contaminant metal ions in dirt compete for these channels if they resemble structurally ( Cosio et al, 2003 ) . Apoplastic ( extracellular ) or symplastic ( intracellular tract ) is adopted for the conveyance of metals through the root and into the shoot via the xylem tissue. They travel with the xylem sap towards the foliages and are loaded in the foliages and shoot. Metallic elements may be stored in different types of cells of the foliage like the mesophyll or the cuticular cells. Arabidopsis halleri shops Zn in its mesophyll cells ( Kupper et Al, 2000 ) . The signifier in which the metal is stored besides depends on the works in some instances. Pteris vitatt a conveyances arsenite ion more expeditiously to the fronds than arsenate ion ( Wang et al, 2002 ) . In some instances, while the toxic metals are being transported to the foliages they may be converted to less toxic signifiers by complex formation or transmutation. This falls in the class of phytotransformation. Endogenous works compounds go through chelation with the toxins therefore changing their toxic belongingss. Segregation or storage of metal contaminations largely occurs in the vacuole off from any cellular metabolic tract that it may upset. The metal ions frequently remain in the cell-wall when the metal-ligand complex base on ballss though to come in the works cell because of the negative charges that the cell-wall holds ( Peer et al, 2005 ) . Segregation may happen in different compartments of the cell wall and in the vacuole varying from works to works. For illustration in Pteris vittata Arsenic is sequestered in extra-cellular and sub-cellular compartments while in Hol cus lanatus segregation occurs in vacuole. 3. Absorption of contaminations by works roots: This mechanism of consumption of contaminations in roots is dependent on the high surface country biofiltration system formed by the roots and is really efficient in ab/adsorbing pollutants particularly from H2O. This is frequently termed as Rhizofiltration and is chosen to take toxic contaminations from H2O systems like watercourses or agricultural tally away set up, industrial discharges and atomic wastes etc ( Salt et al, 1998 ) . First of all the workss are given a little sum of the contaminations in order to acclimatize or accommodate them. Once the workss are adapted to that stuff and can absorb it they are transferred to the existent site where they take up every bit much of the contamination as they can. Once the roots are saturated the workss are harvested. Plants with big root country are preferred because the whole procedure is dependent on soaking up and surface assimilation on the roots. There are opportunities that alimentary consumption will be blocked by the metal consumption because both occur through the same way. To extinguish this a ‘feeder bed ‘ is introduced ( Dushenkov et al, 1995 ) . This is an unreal dirt bed a few centimetres deep on which foods and fertilisers are applied. Plants get their nutrient from this bed, while the roots move down farther and make the site of taint excessively. Here they remove the contamination from land H2O and dirt so the two procedures do non halter each other. Many different biological procedures are involved in rhizofiltration like intracellular consumption by roots, deposition of metals in vacuoules, and translocation of metal to shoot. Deposition can happen both inside and outside of cells in the signifier of a dense aggregation, as in the instance of lead which can be seen through microscope ( Malone et al, 1974 ) . Inside the cell it occurs in vacuoles while outside in cell-walls. Lead exists as lead carbon ate in cell-wall ( Kumar et al, 1995 ) and besides binds through anionic binding ( Broyer et al, 1972 ) . It was seen by Salt and his co-workers that aqua-cultured ( grown in aerated H2O ) seedlings showed much better rhizofiltration than roots themselves ( Salt et al, 1997 ) . They called it Blastofiltration. The ground is the invariably increasing surface to volume ratio of the germinating seedlings as they are in a really immature phase of growing. 4. Removal by transition of contaminations into volatile signifier: The procedure in which workss take up contaminations in dissolved signifier with the H2O through their roots from the dirt, transport them to their foliages and so let go of them into the atmosphere via transpiration through their pore is called phytovolatilization. Compounds like Se and quicksilver are volatilized as such or can besides be converted into their biomethylated signifiers to be volatilized as in the Selenium which is foremost converted to dimethylselenide by bugs and algae and so phytovolatilized by works ( Neumann et al, 2003 ) . Brassica juncea has been identified to expeditiously take Se from dirt by volatilization ( Bauelos et al, 1990 and Bauelos et Al, 1993 ) . It was proposed that Se volatilization as methyl selenate is one of the chief mechanisms of its remotion ( Zayed and Terry, 1994 and Terry et Al, 1992 ) . A outstanding research was done in this field utilizing Arabidopsis thaliana which co ntained mercurous ion as HgCl2 ( Rugh et al, 1996 ) . Elemental quicksilver is in liquid signifier and is much more easy volatilized. A cistron coding for mercurous ion reductase was introduced into the works which reduced mercurous ion to elemental quicksilver therefore increasing quicksilver vapor production as compared to normal workss. 5. Immobilization of contaminations at the site: Here contaminations are stabilized by curtailing their motion in dirt. This is done through minimising free dust, by diminishing dirt eroding and cut downing the bioavailability and solubility of contaminations. The add-on of alkalising agents, phosphates, organic affair and bio-solids lessenings the solubility of polluting compounds in the dirt and therefore prevents it from making land H2O. Plants that have high transpiration rate like grasses etc are helpful for phytostabilization because they decrease the sum of land H2O which is taking off or assisting the contaminations mobilise in the dirt ( Suresh and Ravishankar, 2004 ) . Unlike phytoextraction, or hyperaccumulation of metals into shoot or tissues, phytostabilization chiefly focuses on segregation of the metals in the root zone but non in works tissues. Consequently, metals become less bioavailable and injury to livestock, wildlife, and worlds is reduced ( Mendez and Maier, 20 08 ) . It can be applied temporarily to immobilise the contaminations at the topographic point and halt them from distributing in the country. One must at all times be careful of the fact that a reversal of metal immobilisation can happen, with associated unfavourable environmental effects ( Alkorta et al, 2010 ) . Experiments have shown that phytostabilization has been successful in take downing the degree of lead in a sand mixture. Metal leaching or flight is reduced by change overing metals from a soluble oxidization province to an indissoluble oxidization province for illustration the transition of available toxic Chromium IV to unavailable and less-toxic Chromium ( Agarwal, 2005 ) . 6. Conversion of contaminations to less toxic compounds: Contaminants present around the works are degraded into less toxic compounds by the works itself through it enzymatic metamorphosis or the bugs in the rhizosphere carry out this transmutation. The latter instance has already been discussed as rhizosphere microbic debasement. Once the works has taken up the contamination it will hive away it in the vacuole so that its metamorphosis can be done subsequently or it will be converted to Carbon dioxide and H2O and so transpired. A common job is that of pesticides that is sprayed on workss and can go toxic for human ingestion excessively. Atrazine a pesticide is transformed to anneline ( Agarwal, 2005 ) . TCE and other chlorinated dissolvers are transformed to carbon dioxide, H2O and chloride ion ( Peer et al, 2005 ) . Poplars have widely been studied for their phytotransformational belongingss. Ammunition waste like TNT, RDX and HMX are partly transformed by them ( Thompson et al, 20 09 ) . Once the toxic compounds are broken down into smaller constructions, it can be incorporated to organize new works stuff or released as organic dirt constituents. Plants produce enzymes that have active sites that can adhere and move on common organic compounds frequently taken up by workss from dirt or other beginnings. For illustration the organic compound Nitrotoluene is wholly degraded by nitro-reductase and laccase enzyme. Besides aromatic ( cyclic ) compounds even if they are non organic can be acted upon by enzymes like oxido-reductase nowadays in the foliages, roots and roots of workss. Decision While the human race is confronting jobs in economic sector, its jobs are being multiplied by the depletion of natural resources. One of the major reverses being experienced now is environmental debasement which can be fought really efficaciously by the use of workss. This helps in keeping non merely our natural resources of a clean ambiance and dirt but besides lead to a healthy nutrient web. Phytoremediation has successfully given us parts of Earth with lowered degrees of toxic metal contaminations in its dirt. On the other manus the same belongings of workss to roll up metals in them has been utilized to extinguish hint metal lacks in animate beings. Unique set of biological mechanisms of workss are studied and so applied as Phytoremediation. Plants give an consequence which is non merely aesthetically pleasant but helps halt the devastation of environment excessively. Feasibility of the technique being used can be checked by first analyzing the site to be remediated and so make u p one’s minding what technique ought to be used. This field of biotechnology has opened new doors towards a really bright and promising future-use of workss other than in agribusiness. All of this process is really cheap and this extremely preferred but the drawback is big span of clip required for efficient consumption of heavy metal or any other toxic compound being removed from the dirt country or H2O being remediated. Although Phytoremediation, being a non-agricultural usage of workss, may non assist in feeding the hapless portion of the universe but still its application will give a healthy environment assuring a better quality of life.

Introduction Hyper Inflation Has Plagued Most Of The Worlds Developin Essay Example For Students

Introduction Hyper Inflation Has Plagued Most Of The Worlds Developin Essay Introduction Hyper inflation has plagued most of the worlds developing countries over the past decades. Countries in the industrialised world, too, have at times duelled with dangerously high inflation rates in the post WWII era. With varying degrees of success, all have employed great efforts to bring their inflation rates within acceptable limits. Generally, a moderate rate of inflation has been the ultimate goal. More recently, however, a few countries have pursued policies that strive to eradicate inflation altogether through complete price stability. This has proven to be a contentious enterprise, which clearly indicates that there is still no universally accepted solution to the inflation problem. Indeed, there is not even an agreed consensus regarding the source of inflation itself. The monetarist perception that the root of inflation is solely the excessive creation of money remains. So too does the belief that inflation originates in the labour market. And amongst a variety of others, the opinion that inflation serves the critical social purpose of resolving incompatible demands by different groups is also strong. This last, and more widely accepted, case shows that the problem is hardly a technical one; but rather a political one. It highlights the now unquestionable fact that politics and inflation are inextricably linked. And as with all inherently political issues, consensus is difficult, if not impossible, to achieve. But, political characteristics do provide flexibility. In some countries, high rates of inflation have clearly been compatible with rapid economic growth and fast rising standards of living. In such cases, it is quite reasonable to suggest that higher rates of inflation are acceptableperhaps even necessary. In this setting, it is by no means clear that pursing a policy to stop moderate inflation is either required, or in the best interests of the mass of the population at all. While inflation guarantees that some will gain at the expense of others, the redistributions of income and wealth which do take place can, on normal value grounds, be quite desirable. In other circumstances, it may be quite desirable to place strict controls on inflation, or strive to keep it at ?zero level. Policies aimed at virtual price stability have been in use by central banks in Europe, New Zealand, and Canada over the past few years. Such policies have been particularly focused in Canada. As noted by Pierre Fortin, the only objective the Bank of Canada has pursued since 1989 has been to establish and maintain the inflation rate at ?zero level, which it sees as a CPI inflation rate that is clearly below two percent (italic added). To the surprise of many, it has been incredibly successful, achieving its objective several years before schedule. Although separated by only a few percentage points, Canadas policy is a sharp contrast to the moderate and balanced approach used in the U.S. Since 1989 the Federal Reserve has been satisfied with achieving an inflation rate of around 3 percent. In setting the interest rate, it has continued to pay explicit attention to real economic growth and employment, with the result that the U.S. unemployment rate is currently in the 5 to 6 percent range. Based on this statistic alone, it can be argued that the more moderate U. S. approach has enjoyed greater success than the deflation oriented policy pursued by the Bank of Canada: Canada continues to be burdened with a higher rate of unemployment. Yet, it continues to believe that the unemployment costs of low inflation are ?transitory and small . The directors of most European Central Banks also continue to support this dogma. Clearly, the credibility of the classical idea that the Phillips trade off between inflation and unemployment disappears in the long run is still very high throughout the world. But, in Canada, as in most of Europe, the waiting continues. This is not to suggest that the waiting game has been silent and entirely pleasant. Indeed, the relative lack (or lag!) of success of zero inflation policies and strict price controls has spurred much heated debate. As a case in point, more people are curious why Canada has exclusively focused on inflation cutting and turned a blind eye to the more balanced, and arguably more successful, approach adopted by the U.S.. Is it actually desirable, or wise, to aim towards virtual price stability? Are there real long-term benefits to low, or zero, inflation? What are the real effects of low inflation? The intensity of the ongoing debate on these issues provides evidence that there are no straightforward answers. The purpose of this paper is to probe at these issues in an attempt to cast some clarity on the debate. Appropriately, it begins with an analysis of the consequences of low inflation on the conduct of monetary policy. As is well known, these effects are controversial, and this paper in no way purports to end the deadlock. Bringing the relevant issues to the fore, however, is equal to carrying a well-stocked toolbox that contains many of the necessities for well-crafted opinions. The Consequences of Low Inflation on Monetary Policy In recent years, monetary policy has been promoted to the centre stage of economic policy making the world over. This is a contrast to the first half of the 20th century when it was relegated solely to experimentation in the shadows. During these early years, fiscal policy was solely used; due in part to the depression of the thirties, and the remainder, to the process of post WWII reconstruction and the Keynesian doctrine that fiscal action was necessary to prevent deficiency in aggregate demand. By the late sixties and early seventies however, most of the developed world was witnessing the emergence of a combination of high inflation and low growth; i. e., stagnation, and the revered Keynesian analysis was unable to devise plausible responses to the phenomenon. Consequently, monetary policy emerged as an eminent instrument of economic policy, particularly in the fight against inflation. Issues related to the conduct of monetary policy worked their way to the forefront of policy debates during the 1980s as growth and price stability were the intermediate and long term objectives. Gradually, a loose consensus emerged among industrially advanced countries that the dominant objective of monetary policy should be price stability, and from the outset of the 1990s, this belief has increased in popularity. However, differences continue to exist among central banks with regard to the appropriate intermediate target. While some consider monetary aggregates and, therefore, monetary targeting as operationally meaningful, others focus exclusively on interest rates-even though the inter-relationship between the two targets is well recognised. Again, as with all inflation-related issues, there seems to be little consensus. Though it will only be noted in passing here, monetary policy has also gone through a renaissance in developing economies. Much of the early literature on development economics focused on real factors such as savings, investment, and technology as the main springs of growth. Very little attention was paid to the financial system as a contributory factor. Indeed, through the years countless opinions have highlighted that inflation is endemic in the process of economic growth and is accordingly treated more as a consequence of structural imbalance than as a monetary phenomenon. However, with a growing body of overwhelming evidence, it has become clear that any process of economic growth where monetary expansion is disregarded also leads to inflationary pressures with resultant impacts on economic growth. Thus, price stability and monetary policy have assumed increased importance all over the world, in developing and developed economies alike. Yet, the widespread use of monetary policy to control inflation does not necessarily muffle the roars of policy debate. In fact, the extent to which price stability should be deemed to be the over-riding objective of monetary policy has become an increasingly heated topic of discussion. The crucial question seems to be whether the pursuit of low inflation; (i.e., price stability) through monetary policy undermines the ability of an economy to attain and sustain higher growth. A substantial body of research occupies the examination of this trade-off, whose roots trace back to the Phillips curve (1958) which demonstrated the inverse relationship between the change in wage rates and unemployment rates. It was here that the suggestion of a trade-off between inflation and unemployment was first laid. Although the ?Phillips relationship has subsequently been challenged on theoretical and empirical grounds, it continues to form an important locus of analysis and it is prudent to look at in some detail below. The Phillips Curve It is well known, and generally accepted, that the downward slope of the Phillips curve arises basically because of the presence of money illusion and expected inflation deviating from actual inflation. Based on this knowledge, and its subsequent critiques, the prevailing inflation/monetary policy controversy centres on the possible short-run and long run trade-off between inflation and unemployment. Fences By August Wilson Essay The benefits of price stability are elusive and the costs of achieving it are large. And zero inflation may not be a good thing even in the long run. Critiques focused specifically on the Bank of Canadas policy further argue that the Bank has been overly obsessed with reducing inflation to the detriment of other concerns. Bringing down inflation in the early 1990s required a harsh contractionary monetary policy, with extremely high short-term interest rates. For these observers, the Banks tight monetary policy was badly mistimed, since it was applied during the recession of the early 1990s and the precarious recovery that followed. Critics also suggest that the Bank of Canadas policy surely has important long-run costs. Their argument relates to so-called ?hysteresis, which refers to the case where a variable that has been shifted by some external force does not return to its original state once the external force has been lifted. In the Canadian macroeconomy, it is argued that hysteresis took place when the recession increased the ?natural unemployment rate by creating new structural unemployment. As such, the economys self-stabilising tendency was hampered which damaged the economy because its potential level of real output decreased. To some degree, this explanation helps explain the stubbornly high rates of Canadian unemployment in the 1990s. Critics are also quick to point to another important cost of the Bank of Canadas contractionary policies during the early 1990s. High short-term interest rates have caused the interest bill on outstanding government debt to increase. And , by pushing down both real income and employment, the Bank has reduced government tax revenues. A vicious cycle has been the consequence, with the federal governments added interest obligations and sagging tax intake forcing it to run higher yearly deficits which have increased public debt even further. Thus, despite the success of reaching low inflation targets, low inflation monetary policy does tend to raise unemployment, either directly or indirectly. This can occur through its effects on investment or otherwise, unless the policy generates a great increase in confidence and public expenditure cuts. As the Canadian case demonstrates, this may not be possible. The danger of a narrowly focused monetary policy, then, is that if unemployment rises more than expected, which may well happen, political pressures are likely to be generated leading to the abandonment of the experiment. In Canada, the pressure is increasing, and though virtually independent of the government, the Bank of Canada may not be able to withstand the costs of the experiment for much longer. Abandoning the policy, however, would also be very costly in that, by undermining confidence in the authorities capability and determination, it would make it almost impossible for the Banks future policies to have beneficial direct effects on expectations. The alternative strategy of defining a target path for unemployment, though liable to be condemned by the public as ?cold-blooded, might minimise this risk and thus lower the expected unemployment cost of the ultimate reduction of inflation. But, this too may prove to be different in practice. Empirical studies have shown that, contrary to the prevailing beliefs of many economists and central bankers, in the long run, a moderate steady rate of inflation permits maximum employment and output. Maintenance of zero inflation measurably increases the sustainable unemployment rate and correspondingly reduces the level of output. Zero inflation inflicts permanent real costs that are much larger than envisaged by present-day policy makers. Following Canadas path to zero inflation, empirical modelling demonstrates that the instigation of a policy of zero inflation immediately reduces employment, and it continues to decrease until the third year of the zero inflation ?experiment. The effects of wage rigidity mount as inflation approaches zero, increasing the incremental unemployment cost of reducing inflation further. The zero inflation rate target is not reached until the 6th year, at which point unemployment has reached 10. 8 percent. Unemployment declines gradually from that point, nearing its steady state rate of 8.4 percent after a decade. Without much surprise, this does very closely reflect the effects of the zero inflation monetary policy pursued in Canada. Policy makers should not be satisfied with an ultimate unemployment rate of 8.4%. Not only is this rate of unemployment still high, but the costs involved in securing the target are certainly not worth it. Observations and Conclusions Inflation, both high and low, clearly poses great problems on the macro and micro economy. In higher doses, inflation erodes peoples savings, endangers economic growth and propagates social instability. So, it has been argued, why not in these more disciplined times try to eradicate the disease altogether, just as the world has gotten rid of smallpox? Why not, some central bankers and economists are asking, aim for zero inflation at least in the industrial countries? Only in recent years has this question even been feasible. Previously, if inflation was single digit, it was quite acceptable. Now, however, the world is entering an era of low inflation that brings more ambitious targets within reach. According to the International Monetary Fund, average inflation in the industrial countries is running at only just over 2 percent a year, and although the rate is much higher in the developing countries, it is falling quickly. As shown in this study, the proliferation of low inflation monetary policies to pursue virtual price stability is at the root of this phenomenon. However, as shown in this paper, zero inflation objectives are not wise: Central banks and governments may be trying to kill something that is not capable of being made extinct. This is particularly true in the era of globalisation. Fiercer global competition and freer world trade, low oil and commodity prices, the declining power of labour unions, the growing resistance of consumers to price increases, and the heavy penalties imposed by financial markets on undisciplined governments are working to complicate monetary policies, and further make zero inflation impractical. Thus, even if ?zero or low inflation is readily achievable, as it seems to be, it does so in the face of very powerful variables. But, there are several additional reasons to end zero inflation policies. Above all, this paper has demonstrated that the macroeconomics of low inflation is a delicate science. Macroeconomic performance is very different when inflation falls lower half of the 1-3 percent range than in the upper-half of the 2-4 per cent range, particularly in the long run. Numerically small, but effectively huge, differences arise from the sharp non-linearity of the long-run Phillips curve at low inflation rates. Wringing the last drops of inflation out of the system has painful consequences for growth, jobs and investment that are neither politically acceptable nor economically desirable. Though central banks are reluctant to see the logic of this argument at the moment, the time may soon come when the credibility of giving up zero inflation experiments will be greater than their continued pursuit. A prerequisite to this, in all likelihood, is that the least unemployment costly path for stabilising prices must be found. And, unfortunately, this is a difficult, if not impossible, pursuit. From all of the confusion, what is clear is that a little inflation, perhaps 1 to 3 percent, is a far more efficient policy choice than zero inflation. Such a moderate inflation target would allow real wages to decline where necessary without firms having to impose wage cuts or fire workers. Thus, rather than misusing their energy pursuing zero inflation, governments should be exploring the other policy options now available. In todays low-inflation environment, central banks can afford to be less restrictive than they have learned to be over the past two decades and allow greater room for growth. Exchange rates can, if necessary, be nudged downward without automatically provoking the wage and price spirals they did in the past. Such examples are not necessarily a panacea for the damage caused by zero inflation experiments so far, but they are certainly less harmful. As argued by Pierre Fortin, public opinion is starting to reflect the reality that promised ?large benefits from zero inflation are actually a mirage and that the ?small unemployment costs are actually huge. This opinion has been voiced particularly loudly by Japan and France. And unless the elusive benefits of zero inflation soon manifest themselves, it is only a matter of time before the rest of the ?no inflation pack realises they are barking up the wrong tree.

Dantes Inferno The Levels of Hell

Level One According to Dante, there are various levels in hell. The first level in Hell is called Limbo. All the individuals who die before being baptized and those who live as virtuous pagans are condemned to spend the rest of eternity at this level. The people being referred to in this level are those who die before accepting Christianity.Advertising We will write a custom essay sample on Dante’s Inferno: The Levels of Hell specifically for you for only $16.05 $11/page Learn More All the individuals who die non-Christians, including philosophers who typically do not associate themselves with any religion are going to be condemned to this level for eternity. Some of the examples that provided by Dente include famous philosophers like Socrates and Plato. This level is therefore the least severe in terms of punishment and is the farthest from Satan. Level Two The second level is known as lust and consists of the desperate and the despondent. All th e sinners who will be found to be guilty of lust will be condemned to this level for eternity. The souls of all the individuals found guilty of this sin will be scattered and blown about without any hope of rest.1 In this level, people will be subjected to eternal unrest and hopelessness. This level is the second farthest circle from Satan and is slightly harsher than the first one, but is not as cruel as the other circles that follow. Level Three The third level consists of gluttons who will be forced to eat and lie down in vile places. In addition, the gluttons will also be subjected to freezing slush, which is allegedly similar to the harsh environment subjected to pigs. The character considered to be the head of this group of gluttons is Cerberus. The conditions at this level will be like clumps of mud and other deplorable areas. The gluttony level will be harsher than the previous two levels and this means that the level of torture subjected to the culprits will also be higher. In addition, the surroundings will be characterized by dirt, filth and other bad states. The gluttons will be subjected to states similar to those that pigs experience in this world. Level Four The fourth level will consist of misers and spendthrifts who will be subjected to roll stones to crash them completely. Since they are used to abusing material goods, they will be subjected to stones crashing against each other. Avaricious and prodigal individuals will not be counted among the righteous, but will instead be subjected to banging rocks for eternity. This will be a punishment for spoiling the goods in this world. One of the supernatural beings perceived as a possible leader in this category of people is Plutus, the Greek god.2 The Greek god is perceived to be the luminary of all spendthrifts and misers, and this god will lead all its followers towards this crash. This level will be more severe in terms of punishment than all the other preceding levels.Advertising Looking f or essay on literature languages? Let's see if we can help you!

The wrathful are regarded as those who fight each other and they will be subjected to eternal conflict against each other. Anger and fury will be considered to be part of the fifth level and the perpetrators of these two acts will be subjected to various conflicts in opposition to each other. The wrathful will be condemned to the river of hate known as Styx and this will bring about various sullen lies under the marshy surfaces. The sullen anger will be concealed just as their tempers were silently concealed behind their lives. They will be subjected to unending conflicts between each other and there will be no chance of peace in this level. Since the involved individuals will be subjected to various conflicting scenarios, this level is considered as more severe that the previous ones. Level Six The sixth level will seize all followers of heresy and those who stand for opinions and doctrines that go up against Christian beliefs. All the people who oppose the church and profess opinions that differ from those that are in line with Christian doctrines will be condemned to suffer under this level. Examples of the heretics are Farinata and Epicurean, which are groups of people who presume the soul does not exist.3 These people believe that the core objective of humanity is engaging in pressure. The people who will fall in this category are those who will have developed different opinions and objectives that contravene Christianity. Individuals condemned to this level will have to spend their lives in burning graves for eternity. The punishment in this level will therefore be more severe than in the previous ones. Level Seven The other level in hell is the level that will hold all offenders of vicious crimes and perpetrators of all forms of violence. On e of the forms of violence addressed in this level is that against one’s neighbors.4 This type of violence will hold for all people who wage war against people who are close to them. The other form of violence will be that against oneself. All the people who will be found to have engaged in violent activities against themselves will be subjected to the same punishment experienced by any other violent group. In addition, those who will be found to have acted violently against God will also be subjected to similar punishments, just like any other person condemned to this level. In this level, there will be various rings that one will be subjected, which vary based on the various category of violence. The first ring will consist of those who are violent against others while the second one will be made of individuals who perpetrate violence against themselves. The third ring will include all the persons who perpetrate violence against God. Blasphemy and denial of God’s wor d are considered as some of the most serious crimes under this level.5Advertising We will write a custom essay sample on Dante’s Inferno: The Levels of Hell specifically for you for only $16.05 $11/page Learn More Level Eight The individuals who will be found to have committed fraud will be subjected to the eighth level in hell. The panderers and seducers are some of the main players who will greatly feature in this level. The sorcerers and false prophets who are guilty of the same crime will also be subjected to similar punishments as stipulated under the eighth level. Other persons such as the liars and thieves will also be condemned to suffer in this level. Diomedes and Ulysses are some of the characters who are considered as possible leaders of this level. Level Nine The last level and the closest to Satan is that of treachery. In this level, the individuals who will be condemned are those who betray special relationships, including all trait ors to family members, those who betray their country, those who are disloyal to their guests and those who conspire against their masters. Cain, Judas, Ptolomea and Guelph, are considered as the potential leaders of all the people who will be condemned to this level. This level is therefore considered to be the most severe in terms of punishment as compared to the rest. Bibliography Dante’s Inferno. â€Å"The Levels of Hell.† Danteinferno.info. n.d. Web.

Son of the Revolution essays

Son of the Revolution essays The struggles that Liang Heng went through in the story Son of the Revolution during the reign of Mao are an incredible story of loyalty towards political Party versus family. You can slowly see how Liang Hengs absolute loyalty towards Socialism is slowly swayed through personal trauma and strife as he slowly starts to disregard what the Party says and puts him and his family first. During the time of the Hundred Flowers Campaign, the party urged the masses to speak out and criticize the Partys shortcomings. Liang Hengs mother was originally skeptical about speaking out but after the urging of her superiors, she decided to speak out to please the Party. She said that her Section Head sometimes used crude language and liked to criticize people, that he should give his housekeeper a bed to sleep on instead of making her sleep on the floor, and that sometimes when it came time to give raises, the leaders didnt lead to the masses opinion (page 8). The Hundred Flower Movement then suddenly switched to the Anti-Rightist Movement in which every unit was given quota to find a certain number of rightists to meet and Liang Hengs mother name was a part of her unit quota, she later found out this label was attached to her because of what she had written in The Hundred Flower Campaign. She was sent away for labor reform which was the first division of his family. This incident not on labeled Lings mother as a rightist but his entire family. Liang Hengs father a firm Party supporter did not believe the Party could be wrong and divorced his wife and forbid his children to see their mother to try and distance themselves from her as much as possible, and clear the family name, as soon as his mother was reformed his parents divorced. Although the family cut off their ties with their mother Liang Heng and his family were permanently labeled as having a rightist mother. Two years later hi...

Report on The Green Tea whitening Series Launching Program Assignment

Report on The Green Tea whitening Series Launching Program - Assignment Example In the scanning process, it evaluates the three major competitors of Ginvera. It also gives the result of SWOT analysis. The planning stage also outlines the best marketing strategies for the launching program. It gives detailed findings by describing the best planning process for the launching event. The doing stage states how the marketing team would implement the plans for the launch, and how they would evaluate the success of the event. It concludes with the finding and gives recommendations on how the organization could improve on the launching program. Dr.Tor Lam Huat established The Ginvera Beauty Company in 1985. It originated from Singapore but with time, it has grown and established itself in more than fifteen countries, including Europe. The majority of the consumers associate this company to its Bio-essence products, such as the face lifting cream, and the wide range of products it has launched in the past (Kimoko, 2011). The beauty products involve skin care, body care a nd hair care products. The company’s mission is to be a caring and innovative organization that brings youthfulness and beauty to the public (L.D.Waxson (S) Pte Ltd, 2013). It has a special concern for its consumers and, therefore, strives to manufacture products that are safe and user friendly. It has a vision of being the leading global manufacturing organization for beauty products (Group History, 2013). The company has manufactured a new product, The Green Tea whitening Series. The skin care product protects the skin from damage from the sun’s rays because of its green tea content that delays the oxidation process, hence, an anti-aging product (L.D.Waxson (S) Pte Ltd, 2013). Therefore, the company had to conduct market research to identify the target market, the best location for the launching event, the best product price, placement and competitors. The researchers collected data through interviewing consumers who used the Ginvera Beauty Products, issued questionn aires to randomly selected consumers from the social media and benchmarked the Injex U.K Ltd that was about to launch its new SHIREEN-Poring cosmetic treatment, which was also an anti-aging product (Jonathan, 2013). The Scanning Phase The research showed that the beauty world is dynamically changing and therefore the best planning framework is the strategic planning process because it is cost-effective and aids employees to adapt to the demanding market. The process involves three phases: the Scanning, planning and doing phases (Gru?nig & Ku?hn 2005, p67). The scanning phase ensures there is an evaluation of the market. The marketing department, in this phase, has to collect and analyze data, which would affect the launching program positively or negatively (Ottman 2011, p121). The collection and analysis of data would ensure that the event is at par with the vision and mission of the organization. From the Shireen benchmark results, the marketing manager has to ensure that the comp any analyses its competitors in order to identify its strengths, opportunities, weaknesses and threats in the market. Competitors There are three major competitors in the market (L.D.Waxson (S) Pte Ltd, 2013). The Ganga Prasad Puneet Kumar has a large product line. It has a better financial position than the Ginvera hence a larger production capacity. Its high level of experience in the R&D department enables it in the production of more innovative products that stand out in the market. An advantage of Ginvera over the company is its high marketing strategies and attractive packaging. The Radico Fashion Pvt Ltd poses as

Peer review - Coursework Example why the University of Marion introduced the LessThanUThink campaign in order to sensitize students on the importance to focus on their studies rather than engage in irresponsible activities such as excessive alcohol consumption. The author should include the effects of alcohol on student performance and graduation rate. It is significant to note that as discussed in the proposal, the author gathered evidence from University students that they usually consume very large volumes of alcohol mostly during the weekends to get wasted. According to them, they do this for fun and an individual can end up guzzling up to over ten drinks in a night. However, this heavy drinking results in personal tragedy for college students and their families. Yes, the draft proposal persuades in the way the author has answered the problem of the proposal. The author has stated the reasons why the campaign was launched. The campaign in the University was successful since after the campaign was launched, it has assisted educate students when others engage in irresponsible drinking. There is no need for change or reorganization of the paper but the author should state the research design of the study and the methods they used to gather information about binge drinking in the University of Marion. The author was very keen and specific thus they avoided any form of repetitiveness. The most interesting part is the statistics about the past drinking behavior of students at the University of Marion. The statistics were shocking and needed immediate intervention to avoid further damage to the students and the reputation of the University. For example, I learned that about 25 percent of college students report academic consequences of their drinking including missing class, falling behind, doing poorly on exams or papers, and receiving lower grades

He remarked that not only scientific and technical, but also purely economic and business advancement of the U.S. are strongly dependent on the new generations’ capacity for making rational and creative decisions. And for this end, the high-quality education, and the students’ resolve to attain it, is indispensable. I would note that Barack Obama’s speech underscored the planned administration’s policies aimed at boosting the youngsters’ resolve to follow through their school years without dropping out. The main concern that may have been discerned in the speech is that over the youth’s contribution to the society’s performance in such fields as the economy and science. Both fields are greatly affected by the current crisis; therefore, it is natural that the President should draw attention to them in his

Techniques For Airflow Rate Measurements

Techniques For Airflow Rate Measurements My company is setting up an experiment to measure the airflow rate in a duct. Airflow measurement techniques are necessary especially in many industries. Some of the common airflow measuring applications include ventilation testing, air balancing, ductwork, air planes and so on. Many research and studies have been put into improving and inventing new equipments to measure air flow. This is so to enable user to get the most accurate result and at the same time using the least cost. This report outlines the different airflow measurement techniques and devices that are available today. There are many different types and ways to measure air flow but I will concentrate on those that are more popular and commonly used. They are the Pitot-tube, Orifice plate, Venturi meter, Cup anemometer, Sphere anemometer and Hot-Wire anemometer. Techniques and devices for airflow rate measurements 2.1 Pitot tube A pitot-static tube is used in wind tunnel experiments and on airplanes to measure the air flow rate. It is also used in many industrial applications. It was invented by the French engineer Henri Pitot in the early 1700s and was later modified to its modern form in the mid 1800s by French scientist Henry Darcy. It is a slender tube that has two holes on it (Figure 1). The front hole is placed in the airstream to measure whats called the stagnation pressure. The side hole measures the static pressure. By measuring the difference between these pressures, we are able to get the dynamic pressure that can be used to calculate the air velocity. By Bernoullis principle, Stagnation pressure = static pressure + dynamic pressure Solving that for velocity we get: Where V: fluid velocity; pt: stagnation or total pressure; ps: static pressure; à Ã‚ : fluid density Figure 1: Pitot-Static Tube The incorporation of sensors to measure the air temperature, barometric pressure, and relative humidity can further increase the accuracy of the velocity and flow measurements. The Pitot tube can also measure the velocity with the use of a pressure transducer that generates an electrical signal which is proportional to the difference between the pressures generated by the total pressure and the static pressure. The volumetric flow is then calculated by measuring the average velocity of an air stream passing through a passage of a known diameter. When measuring volumetric flow, the passage of a known diameter must be designed to reduce air turbulence as the air mass flows over the Pitot tube. To obtain an estimate of the volumetric flow in the duct from a series of pitot-static tube velocity measurements, one must integrate the velocity over the duct area. There are many of different methods for approximating the above integral. One of the methods is to divide the duct cross-section into a number of equal area sectors, and then measure the average velocity at the center of each sectors. For example, we can divide the cross-section of the duct in the figure below: The velocity will be by calculating the sum: 2.1.1 Advantages and Disadvantages The advantages of using pitot-static tube is that it can be inserted in small airstream and it presents little resistance to flow. It is simple, inexpensive and suited for a variety of environmental conditions including extremely high temperatures and a wide range of pressures. The disadvantages would be that if the flow rate is low, the difference in pressures will be too small to accurately measure with the transducer. If the air flow is high (supersonic), assumptions of Bernoullis equation will be violated and thus leading us to wrong measurement. Furthermore, if the tubes are clogged, the reading by the transducer will be inaccurate resulting in dire consequence in the context on airplane. Icing of the pitot tube had caused plane to crash. 2.2 Orifice Plate Orifice plate is used for flow rate measuring in pipe systems. An orifice plate is placed in a pipe containing a fluid flow, which constricts the smooth flow of the fluid inside the pipe. By restricting the flow, the orifice meter causes a pressure drop across the plate. By measuring the difference between the two pressures across the plate, the orifice meter determines the flow rate through the pipe. Figure 2: Orifice Plate in a duct Applying Bernoullis equation to a streamline flowing down the axis of the tube gives, Where, P: pressure à Ã‚ : density of the fluid V: Velocity of the fluid As shown in the above diagram(Figure 2), point 1 is upstream of the orifice, and point 2 is behind the orifice. It is recommended that point 1 be positioned one pipe diameter upstream of the orifice, and point 2 be positioned one-half pipe diameter downstream of the orifice. Since the pressure at 1 will be higher than the pressure at point 2, the pressure difference will be a positive quantity. From continuity equation, the velocities can be replaced by cross-sectional areas of the flow and the volumetric flow rate Q, Where, A: cross sectional area Solving for the volumetric flow rate Q gives, The above equation remains true with perfectly laminar, inviscid flows. As for real flows like water or air, we have to take into account of the viscosity and turbulence that are present .To account for this effect, a discharge coefficient Cd is introduced into the above equation to marginally reduce the flow rate Q, Since the actual flow profile at point 2 downstream of the orifice is quite complicated, the following substitution introducing a flow coefficient Cf is made, Where, Ao: area of the orifice As a result, the volumetric flow rate Q for real flows is given by the equation, The flow coefficient Cf is found from experiments and is tabulated in reference books. It ranges from 0.6 to 0.9 for most orifices. Since it depends on the orifice and pipe diameters (as well as the Reynolds Number), one will often find Cf tabulated versus the ratio of orifice diameter to inlet diameter, sometimes defined as b, The mass flow rate can be found by multiplying Q with the fluid density, There are mainly 3 different types of orifice plates. They are Concentric, Segmental and Eccentric. This is to accommodate for different applications so that the meter has the optimum structure. The density and viscosity of the fluid, and the shape and width of the pipe do influence the choice of plate shape to be used. The concentric orifice is the most common of the 3 types. In this design, the orifice is equidistant. It is generally used for clean liquid and gas flow in pipes under six inches, where Reynolds numbers range from 20, 000 to 107. We will therefore use concentric orifice for our experiment purposes. ( which deals with air). Segmental orifice is similar to concentric orifice with regard to its functioning. The circular section is concentric with the pipe while the segmental part is mounted in a horizontal pipe. This installation helps to eliminate of foreign materials on the upstream side of the orifice. Eccentric orifice plates are designed in such a way that the edge of the orifice is reallocated towards the interior of the pipe wall. It is used in similar manner as the segmental orifice plate. Figure 3 below shows the different types of orifice plates: 2.2.1 Advantages and Disadvantages With no moving parts and a simple design, the orifice is easily machined. It is low lost and can be easily inserted into a duct or an existing pipeline with a minimum alteration to the layout. Therefore orifice plate has been a popular device for flow measurement. The disadvantage is that it creates a rather large non-recoverable pressure due to the turbulence around the plate, leading to high energy consumption (Foust, 1981). 2.3 Venturi meter Most of the unrecoverable loss of pressure with an orifice is due to the sudden change in the cross sectional area. The sudden increase of area after the air passes the section of minimum area: the rapid convergence of the stream on the upstream side contributes considerably to the total loss. We are able to recover most of the pressure by leading the stream with the use of a conical length of pipe, with its smaller end of the same cross section as the jet, and gradually expanding in size along the direction of flow until the full pipe diameter is reached. An arrangement of this kind, with a conical entry is known as a venturi tube. The Venturi effect is named after Giovanni Battista Venturi (1746-1822), an Italian physicist. A venturi meter consists of a cylindrical length, a converging length with an included angle of 20o or more, and short parallel throat, and a diverging section with an included angle of about 6o. The internal finishes and proportions are designed in such a way to enable us to achieve the most accurate readings while ensuring minimum head losses. Assuming that the fluid is inviscid with no losses due to viscosity, the velocity at section 1 and 2 are V 1 and V 2 respectively. The velocities are steady and uniform over areas A 1 and A 2 Applying Bernoullis equation to a streamline passing along the axis between the two sections ( 1 2 ). Where, V:Velocity of the fluid P: Pressure à Ã‚ : density of the fluid Z: Height Using continuity equation, Q = A1 V 1 = A 2 V 2 When real world effects such as fluid friction and turbulence are included a correction factor, called the coefficient of discharge, Cd is introduced into the venturi equation giving For low viscosity fluids C d = 0,98. 2.3.1 Advantages and Disadvantages The venturi tube introduces substantially lower non-recoverable pressure drops (Foust, 1981). Therefore venture tube can be used on more viscous fluid. However it has limited range ability. It must be used only on installations where the flow rate is well known and varies less than 3 to 1. It is rather expensive and should be flow calibrated to provide accuracy into the range of +/- 1.00%, Units are big and weigh more than comparable head devices and thus making it difficult to install and inspect. 2.4 Anemometer An anemometer, also known as wind vane is a device for measuring the air flow rate in a contained flow such as duct or unconfined flow. The term is derived from the Greek word anemos, meaning wind. In around 1450, the Italian art architect Leon Battista Alberti invented the first mechanical anemometer which consisted of a disk placed perpendicular to the wind. To determine the velocity, an anemometer detects change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow. They are probably best used mounted on light, preferably streamlined, supports and inserted into the airstream from one side. 2.4.1 Cup anemometer This device consists of three or four hemispherical cups mounted at the ends of horizontal spokes which rotates about a low-friction vertical shaft. An electrical device is used to record the revolutions of the cups and measures the air flow rate. (Figure below) As the anemometer is placed inside the flow stream, the concave surfaces of the cups have higher wind resistance than their convex counterparts and thus producing an unbalanced moment with respect to the center axis. This forces the cups to rotate (see schematic). Under steady flow condition, the rotational speed of the anemometer is directly related to the wind speed, that is: V=rw. There are number of fundamental physical parameters and characteristics of an anemometer that affects the cup anemometer performance. They are: rotor arm length cup area rotor inertia drag coefficient on convex face of cup drag coefficient on concave face of cup static, dynamic and parabolic mechanical friction coefficients for temperature range sensitivity characteristic to out-of-plane attack linearised calibration curve. A well designed cup anemometer should have the following characteristics as shown in the Figure 4 below: Let us examine a cup anemometer rotating at speed w in a free wind speed U: The instantaneous aerodynamic torque on the rotor, MA, is given by: where A: frontal area of the anemometer r: the air density Cdv : drag coefficients for the concave faces of cup Cdx drag coefficients for the convex faces of cup In the steady state, there is perfect torque balance (MA=0), and the equation reduces to: defining l and  µ as the speed and drag ratios respectively: allows further re-expression in a quadratic form: Typical values of Cdv and Cdx are 1.4 and 0.4 respectively, giving a value of  µ of 3.5. The above equation predicts that the consequential speed ratio l will be 0.303, meaning the rotor will rotate at about one third of the wind speed. Note that this solution also proves the theoretically linear sensitivity of the cup anemometer to wind speed. It also shows that the speed ratio is dependent on the drag characteristics of the cup and not the size. Furthermore, the rotational speed is inversely proportional to rotor radius. 2.4.2 Advantages and disadvantages The advantages of the cups are their reliability and ruggedness. The disadvantages are the relatively high threshold velocity (the minimum wind velocity needed to start the cups to turn). It is mainly used to only measure the horizontal component of the wind. Another problem with cup anemometry is the different response time for increasing and decreasing wind velocities due to its moment of inertia. This results in an overestimation of wind speed under turbulent wind conditions as present in nature, the so-called over-speeding. Additionally, the rotation of the anemometer causes a wear of bearing and leads to a recalibrations with time. 2.5 Sphere anemometer Many research and studies have gone into the improving of such a device (Cup anemometer). For example, the sphere anemometer. It was developed at the University of Oldenburg. This sphere anemometer, as shown in figure 4 below, is able to measure the air flow rate as well as simultaneous detection of the air flow direction. It eliminates the problem of wear of bearing as encountered in cup anemometer. Figure 5: The sphere anemometer uses the relationship between the point force F acting on the tip of a rod and its resulting deflection s. (1) Where l: the length of the rod E: the elasticity modulus Ja: the second moment of area. In case of the sphere anemometer, with a sphere radius r much bigger than the radius of the rod rR, the force can be assumed to act only on the tip. The second moment of area is then given by (2) Together with the force acting on the sphere (3) where cd: the drag coefficient of the sphere A: the cross section of the sphere ÃŽÂ ¡: the density of air V: the wind velocity Equation 1 becomes (4) Therefore the deflection of the rod is proportional to the drag coefficient cd and the wind velocity squared. For a calibration it is necessary to know how the drag coefficient cd changes with wind velocities. Table 1 below shows the drag coefficient of a sphere plotted against the Reynolds number (Re) (cf [1]). It can be seen that for Reynolds numbers in the range from about 800 to 200000 the change in drag coefficient cd is negligible. For a sphere with a radius r = 40mm this range in Re corresponds to a range in wind velocities from 0.17m/s to 38m/s using where v = 1.51 x 10-5 m2/s is the kinematic viscosity of air. Within this velocity range the deflection s of the rod is directly proportional to the wind velocity squared. With this direct relation it is easy to calibrate the sphere anemometer over a wide range of wind velocities. Table 1: 2.6 Hot wire anemometer Thermal anemometry is the most common method used to measure instantaneous fluid velocity. The technique depends on the convective heat loss to the surrounding fluid from an electrically heated sensing element or probe. If only the fluid velocity varies, then the heat loss can be interpreted as a measure of that variable. Working Principle Its principle application is the measurement of rapid fluctuations, particularly the study of turbulent flow; in this field it is the only instrument with sufficiently rapid response, and the associated electronic equipment lends itself readily to signal processing needed to record directly such properties of a turbulence as r.m.s values, correlation functions, and spectral distributions. Governing equation Consider a thin heated wire mounted to supports and exposed to a velocity U Where, W: power generated by Joule heating (W=I2Rw) Q: heat transferred to surrounding Qi: CwTw=thermal energy stored in wire Cw: heat capacity of wire Tw: wire temperature The wire is heated electrically and placed in the flow stream. The energy balance of the heated wire at equilibrium is (equation 1): Where, I: an electric current Rw: the wire resistance h: the heat transfer coefficient A: the heat transfer area Tw: the wire temperature Tf: the fluid temperature D: wire diameter Kf: heat conductivity of fluid Nu: dimensionless heat transfer In the forced convection regime (0.02 Reynolds number: Re= (where r is the air density and U is the velocity and  µ is the air dynamic viscosity).(equation 2) Where Substituted Eq(2) into Eq(1), There are two types of hot-wire anemometer used in practice but I will touch on Constant Temperature Anemometer which is more commonly used. For a case of Constant Temperature Anemometer Where And The voltage is a measured of velocity U. 2.6.1 Advantages and disadvantages It has good frequency response as it can measure up to several hundred kHz possible. It is able to measure a wide range of velocity. It is small in size and has rapid response.- Thermal anemometry enjoys its popularity because the technique involves the use of very small probes that offer very high spatial resolution. The basic principles of the technique are relatively straightforward and the probes are difficult to damage if reasonable care is taken. However, deposition of impurities in flow on sensor can alter the calibration characteristics and reduce frequency response. Probe may or burnt out easily if not carefully taken care of. It is unable to fully map velocity fields that depend on space coordinates and simultaneously on time. Furthermore, it cannot work well in hostile environment like combustion. The wire diameter needs to be very small of the order of 0.02mm or less. Conclusion In this report, I have touched on the different techniques and different devices for the measurement of airflow. There are many different devices in the market but many use similar techniques with abit of new inventions or add ons here and there. Different airflow measuring devices utilize different technologies and thus, one needs to fully understand the characteristics, techniques and its pros and cons before selecting the optimal one for use. In summary, an ideal device to measure air flow rate should have the following characteristics good signal sensitivity. It should be able to detect output for small changes in velocity. High Frequency Response: to accurately follow transients without any time lag Wide velocity range Create minimal flow disturbance Good Spatial Resolution Inexpensive High Accuracy User friendly

Platypus Envenomation :: Australian Animals Wildlife Essays

Platypus Envenomation Abstract The duck-billed platypus (Ornithorhynchus anatinus), order Monotrema, can be found throughout river systems in eastern Australia. The males have a retractable spur located on each of their hind legs. The spurs are attached to venom glands that produce a toxic cocktail of at least four different classes of peptides. These four compounds (Hyaluronidase, OvCNP-39, OvNGF, and defensin-like peptides) are highly selective enzymes and polypeptides that work together to inflict excruciating pain and edema that can last for months. The first compound identified, Hyaluronidase, lowers viscosity to allow for a deeper penetration of the venom into tissue. A C-type natriuretic peptide called OvCNP-39 contributes to edema. OvNGF is a nerve growth factor that is responsible for extreme sensitivity to heat and pressure. The role of Defensin-like proteins is not well known, but it is believed that they contribute the pain and edema associated with the venom. An unknown compound has been found to induce Ca++ dependent current in root ganglion cells, which may also contribute to the feeling of pain. Research is being done to identify the roles of these compounds and the possibility of them being used in medicine. Introduction The Platypus (Ornithorhynchus anatinus) is a unique animal that is found only in Australia. It is in the class Mammalia and the order Monotrema. Monotremes are phylogenetically the oldest of the mammals and can only be found naturally in Australia and in nearby New Guinea. They are quite different from placentals and marsupials and are believed to be the link between the reptiles and the other mammals. This is most noticeable though their means of reproduction and waste elimination. Montremes have a cloaca, which is a single opening for passage of solid and liquid waste, where the transfer of sperm takes place, and in females, the laying of eggs. This feature is shared only with birds and reptiles. Platypuses live solo, except during the breeding season. They feed on worms and freshwater crayfish (Cheerax destructor) in eastern Australian rivers (Sutherland, 1983). They have low average body temperature compared to other mammals, which further supports their reptilian evolution (Torres et al., 1999). They can live about 16 years and grow to be 40-50 cm long, with males being larger than females (Jackson, 2003). Venom: Production & Delivery A characteristic that helps add even more to the platypus ¡Ã‚ ¯ uniqueness is the males ¡Ã‚ ¯ ability to produce and deliver venom.

Shall I Compare Thee to a Summer’s Day

Word Count: 617 Teanna Armstrong Enc 1102 Essay #3 March 11, 2013 Sonnet, Theme, and Structure of â€Å"Shall I Compare thee to a Summer’s Day? † A sonnet’s structure has symbolism and it presents the theme in many poems of Literature. In the poem â€Å"Shall I Compare thee to a Summer’s Day? † by William Shakespeare happens to be a sonnet. To begin with, the sonnet mentioned above is called a Shakespearean sonnet. It is composed of three four-line quatrains and a concluding two-line couplet. Certain components of the author’s point are suggested to be based on its structural patterns; components such as thought and feeling.Meaning this sonnet can introduce the subject in the first quatrain, expand and develop it in the second and third quatrains, and conclude something about it in its final couplet. This whole set up helps the reader to capture the theme; and helps the author to organize the theme. As well as, the sonnet’s structure p lays a key role, other than just being a Shakespeare and sonnet. The structure of the sonnet is strictly constrained, and this one in particular is believed to be a fixed form sonnet. Poems in fixed forms are recognized by their rhyme, meter, and repetition.Furthermore, usually in its opening line the central idea of the poems is expressed. The theme of the poem â€Å"Shall I Compare the to a summer’s day† May be stated as: Can someone, or the subject, really be compared to all the components of a summer after understanding the theme it shows the reader that the sonnet is asking is the subject comparable to a summer’s day, making the structure of the poem easier to understand. To illustrate, the theme is hinted in the first half of the first stanza; which starts the order of the sonnet’s theme. It is clearly indicated that the second line: â€Å"Shall I compare thee to a summer’s Day? (874) is the question that he will be answering. This question also shows that a comparison will be made. The question that remains is what is being compared to what. This is answered in the second line, which states â€Å"Thou art more lovely and more temperate† (874). This statement shows that Shakespeare is comparing a summer’s day to a person who is more lovely and temperate compared to the day of a summer. Moreover, the structure of this sonnet has setup the central theme for the reader in the first stanza. What lies in the next two stanzas are details and deeper emotions or thoughts to fill the reader’s mind with illusions of the sonnet.These middle stanzas are placed in Shakespearean sonnets for this essential reason. The details in this particular selection creates more compare and contrast examples between that person and a Summer’s day. Although Shakespeare wrote the contrast and compare by explaining all of the Cons of summer in these two stanzas, and in the last two line, also known as the couplet, he tur ns the direction back onto the person he was speaking of to show what the cons were compared to. Not only that, but Shakespeare also showed meaning in this couplet: â€Å"So long as men can breathe†¦ This gives life to thee† (874).The statement stated before is meaning the opposite of what was said in the first two stanzas about the summer. Instead, Shakespeare is indicating that the person will live on through his poem forever unlike a Summer’s day. In Conclusion, many poems have different components that lead the reader to realize the central theme. In sonnets particularly, everything is placed where it should be for a reason. All sonnets have symbolism and presents the theme in many pieces of literature as explained above. . Works Cited 1. Diyanni, Robert. Literature: Reading Fiction, Poetry, and Drama.

Tips Writing a Research Paper on Bullying

Tips Writing a Research Paper on Bullying Tips: Writing a Research Paper on Bullying Freshmen and students in their first year in high school often fall prey to bullies. Reports obtained from educational institutions indicate that bullying persists even in the modern era. It is not known why people bully others, but it can be concluded that a bully is likely to have an underlying psychological condition that triggers the bullying behavior. On a different perspective, bullying is not only rampant in schools, but has also been reported in family settings. This is mainly witnessed in families where the income is so meager that it cannot support the children that comprise that family. Bullying in families takes a mild form. For example, the eldest sibling taking care of the younger ones might serve himself bigger food portions, leaving the rest to share some insufficient quantity. In the same manner, bullying within the family might be seen where the elder siblings force younger ones to wash their clothes for them, clean their rooms, and run errands for them. All this time, the parents might not be aware that such things are happening. From these examples, it can be gathered that writing a research paper on bullying can be fascinating. Nevertheless, as is common with a fascinating research topic, it is possible to drift out of the point and write an irrelevant essay. Therefore, a number of handy tips that guide and control the writing of a research paper exist. Tip number one involves the definition of key terms. The writer must not assume that every reader knows what bullying is. It is always good to begin any essay with a definition of the topic and the key words that will feature prominently in that essay. Examples of key words that a writer must try to include in an essay on bullying are coercion, threat, and victim among many others. The definition of key phrases and words will be followed by a synopsis about the pervasiveness of bullying in social settings. In this section, the writer will give a statistical background into the major forms of bullying in schools and families, as well as in other social settings where the trend has been observed. After this, the reader will select one situation where bullying has been observed to be notorious. A critical exposition of the situation will be given. This will call for profound information concerning the factors that trigger bullying, and the responses that have been implemented with respect to the behavior. The research paper is not complete if the writer fails to take in the documented effects that have resulted from acts of bullying. Similarly, the writer must outline the positive results that have been generated by the said responses, if there are any. As with any other paper, it is good to conclude the essay with a set of suggested actions the writer feels would aid in deterring bullies. An obvious but imperative tip is to proofread your paper to ascertain that there are no grammatical or typing errors. research paper writing service will provide you with a high-quality customized research project on Bullying topics and ideas. Just fill in the order form with your details.

The main problem that faces applying this work release program is that the offenders could escape during their participation in the program.

Strategic Planning for International Travel Essay

Strategic Planning for International Travel - Essay Example In the "Strategic planning for international travel" essay, the author describes the prevailing situation in the travel industry in the United Kingdom. The importance of International travel, infrastructure and public-private partnership for UK International Travel are described. Most of the European countries belong to the category of developed nation, and the countries like United Kingdom (UK), France, Germany, Italy etc are the major economic powers. As this paper deals with the international travel of UK, the focus will be on this country. European nations are economically and technically developed and hence, their transportation and travel system are quite advanced. UK is one of the leading financial powers of Europe. Its GDP as per purchasing power is nearly $2.189 trillion and per capita GDP is recorded $35,100 during 2010 (CIA, 2011). After the financial crisis of 2007-2008, its economic growth has experienced a steep downfall. However, UK’s economy is now at its recov ering stage and government is trying to bring further developments by encouraging trade and business. Tours and travels is an important aspect for the growth of trade and business and hence, the government is trying to improve its infrastructure and technology for availing better transportation system. The services industries are playing very crucial role in UK as 75% of its GDP is contributed by these services sectors. UK’s services industries include a number of sectors like transport, communication, financial, distribution, distribution, tourism etc. (U.S. Department of State, 2010). Increases trade and business activities in UK have necessitated major infrastructural and

Implementing Measurements and Testing Models Essay

Implementing Measurements and Testing Models - Essay Example Sampling is done primarily because a population may be very large and diverse making it impossible for the researchers to study all of them given the available resources as well as the element of time. The Sloven formula is commonly used to compute for the desired sample size based on the total population and the margin of error or confidence level. The formula for computing the sample size is as follows: To determine the sample population for a study on drug use of prisoners in the State facilities, the researcher may use stratified random sampling. Stratified random sample involves subdividing the population into smaller homogenous groups to get more accurate information (Best, 2003). It is a commonly used probability method that is superior to random sampling because it reduces sampling error. A stratum is a subset of the population that shares at least one common characteristic. Examples of stratums might be males and females, or managers and non-managers. The researcher first identifies the relevant stratums and their actual representation in the population. Random sampling is then used to select a sufficient number of subjects from each stratum. "Sufficient" refers to a sample size large enough for us to be reasonably confident that the stratum represents the population. Stratified sampling is often used when one or more of the stratums in the population have a low incidence re lative to the other stratums (http://www.statpac.com/surveys/sampling.htm) Since prisoners are detailed in several areas spread all throughout Oklahoma, distributing the sample population according to the area or location of the facility and relative to the number of inmates in each area would ensure representation of each facility. Assuming that the survey research will be conducted in the facilities under the Oklahoma State Department of Corrections, and the desired margin of error is 1% or at 99% confidence level, we can compute for the desired sample size of a population such as 20,306 inmates as of December 8 figures in the OkDOC database using Sloven formula - n = N/(1+Ne2) n = 20,306 / 1+ [(20,306 ) (.01) 2 ] n = 20,306 / 1 + [ (20,306) (.0001)] n = 20,306 / 1 + 2.0306 n = 20, 306 / 3.306 n = 6,142.16 or 6143 Thus, the total number of respondents to the survey on drug use among inmates in the Oklahoma State Department of Corrections will be 6,142 inmates. This figure will be drawn proportionally from the different facilities throughout the State according to their actual count of inmates. Based on percentage share computed in Appendix A, the following will be the distribution of inmate-respondent in each facility.
