Abstract: Ghazi Barotha Hydro Power Project is a run of river project meant for generation of 1450 MW electricity. It is Pakistan’s second biggest power generating project of vital importance. Ghazi Barrage, one of the key components of the project and situated just downstream of Tarbela Dam project, diverts the
Tarbela releases towards 52 KM long Power Channel, another key component, which in turn conveys it to village Barotha for power generation through Power House, the final key component of the project. Two factors which necessitated this study were heavy sediment accumulation in Tarbela dam thereby increasing the sediment inflow into the Ghazi Pond and the devastating flood of 2010 which brought huge sediments from the area upstream of Tarbela. It was important to find out what was happening to the Ghazi pond and changes it had undergone since its operation in 2005. The strategy of this study was to find out incoming and outgoing sediment load from the available data thereby evaluating load retained in the pond along-with

    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)…

    SEDIMENTATION According to Brown (1950), sedimentation is the separation of a suspension into a supernatant clear fluid and a rather dense slurry containing a higher concentration of solid. According to Perry (), sedimentation is the partial separation or concentration of suspended solid particles from a liquid by gravity settling. This field may be divided into the functional operations of thickening, whose purpose is to increase the concentration of suspended solids in a feed stream; and clarification…

    SEDIMENTATION ABSTRACT Sedimentation is the process of separating a liquid mixture of suspended particles into clear supernatant liquid and denser slurry having a higher concentration of solids. This is usually accomplished by allowing the particles to settle through the force of gravity, mechanically using centrifugal force, or electrostatically using an electric current. Continuous sedimentation tanks are usually used in wastewater treatment facilities to separate suspended particles from wastewater…

    Title: Erythrocyte Sedimentation Rate (ESR) Aim: To measure the erythrocyte sedimentation rate of a patient to see if there could be anything wrong. Introduction: The erythrocyte sedimentation rate (ESR) is the distance that the red blood cells sediment in a specific time interval. ESR is an easy, inexpensive and non-specific test that is used to help protect conditions associated with acute and chronic inflammation including infections, cancers and autoimmune diseases. ESR is said to be non-specific…

    The Effect of Dams on Reservoir Sedimentation and Environmental Flow A dam is a barrier, obstruction or blockade built for the sole purpose of storing water. There are many uses for these systems, including its combination with hydropower, and the re-distribution of the deposited water. The benefits of the dam are very valuable to everyday life. They provide flood control, water supply, fishing hydroelectric power, recreation and more. But just as we figure out how to improve energy efficiency…
