ERYTHROCYTE SEDIMENTATION RATE | -AND ITS VARIATION | | ABSTRACT: The Erythrocyte Sedimentation Rate (ESR)‚ also branded as sedimentation rate or Biernacki Reaction‚ is the rate at which red blood cells sediment in a time of 1 hour. To execute the test‚ anti-coagulated blood is positioned in an erect tube‚ known as a Westergren tube‚ and the rate at which the red blood cells fall is calculated and accounted in millimeters per hour (mm/h)

fiscal policy designers should opt for a flexible exchange rate system. Nations‚ however‚ which do not have such policy makers should opt instead for a fixed exchange rate system. When attempting to stabilize an economy‚ monetary policy is the most efficient weapon that policymakers possess (Weerapana‚ 2003). In other words‚ it is much simpler to enact monetary policy than fiscal (Weerapana‚ 2003). Some nations benefit from a fixed exchange rate system‚ however. Nations such as Brazil‚ Kenya and Turkey

Examine the main trends in the birth and death rates in the UK since 1900 As the population of a country increases‚ there will be certain factors affecting the people of that country; the birth rate‚ and the death rate are two of the major demographic trends. Since 1900 the UK has changed greatly‚ as has the demography of the country. The Birth rate - the number of live births per 1000 of the population per year originally was fairly high due to the fact that child labour was legal in Victorian

Spot Rate and Forward Rate Spot Rate: It is nothing more than the YTM on bond. It is the rate of interest on bond maturing at any time in the future. It is also known as geometric average of 1 year forward rates in the future. Hence‚ YTM on bonds can be calculated as: When forward rates are given then; oS1 = oF1 oS2 = [(1+of1)(1+1F2)](1/2) -1 oS3 = [(1+of1)(1+1F2)(1+2F3)](1/3) -1 and so on. Forward Rates: It is the interest rate established today ‚ that will be paid on money to

Homeostasis of BP and Heart Rate A normal blood pressure can be identified by having a systolic pressure of around 120 and a diastolic pressure of around 80. This value is expressed as "120/80". A normal heart rate is expressed as the amount of times it beats in a minute; a normal adult heart rate is between 60-100 beats per minute (BPM). There is a relation between these two measurements‚ but they are stimulated by several different circumstances. The blood pressure is mainly affected
