March‚ 2010 Title: Investigating the capacitance of a parallel-plate capacitor using a reed switch Objective: To investigate the factors which affect the capacitance of a parallel-plate capacitor using a reed switch. Apparatus: - reed switch - signal generator - capacitor plates of area about 0.24m X 0.24 m 1 pair - polythene spacers ( 10 X 10 X 1 mm ) - polythene sheet‚ same area as capacitor plate 1 mm thick - battery box with 4 cells

Usually require open reduction and internal fixation Barton’s fractures are almost impossible to treat by closed means. Buttress plate fixation of volar Barton’s fractures is usually necessary. Type III compression injuries o Require operative treatment if Intraarticular damage is significant Radial shortening is severe o Fixation with multiple Kirschner wires or plates is often necessary‚ and cancellous bone grafting is frequently required to fill impacted areas. o Often a combination of open and

Continental drift is the idea that the earth’s continents are drifting away‚ relative to each other across the ocean bed suggested by Alfred Wegner as part of his wider theory on plate tectonics. The plate tectonic theory suggested by Alfred Wegner in 1915 was that millions of years ago all the continents were joined together in one mass of land called ‘Pangaea’‚ the evidence for this was that coal was found on Antarctica‚ the shape of Africa and south America fit together and same fossils were

Outline the relationship between plate movement and volcanic activity (10 marks) Volcanic activity mainly tends to occurs on the edge of plate margins‚ but could potentially occur at any location‚ such as Hawaii where the plate boundary is underneath a hot spot‚ which causes the Hawaiian chain islands. It is where the magma in the mantle breaks through the lithosphere to form extrusive landforms. Shield volcanoes can be formed due to subduction and they tend to start of as a submarine volcano

Blue on Agar Plates at Different Temperatures Abstract: Diffusion is the movement of particles from an area of high concentration to an area of low concentration wherein substances are independent‚ rapid and in random motion which frequently collide with each other in the sides of the container. This study aimed to assess the influence of temperature on the diffusion rate of methylene blue on agar plates. To determine the relationship between the two variables‚ five set-ups of agar plates were prepared

Methyl Red and Voges-Proskauer Test The Methyl Red test shows which bacteria are creating stable acids through mixed acid fermentation of glucose. This helps to identify enteric bacteria by examining how they metabolise glucose. Every enteric bacteria first produces pyruvic acid from metabolism of glucose. A methyl red positive enteric bacteria‚ uses the mixed acid pathway when breaking down pyruvic acid to different acids‚ like lactic‚ acetic‚ and formic acids. The Voges-Proskauer test determines

June 2011 plate tectonics and associated hazards Comment on the extent to which the features shown in the image support the theory of plate tectonics. To begin with we can see that many of the landmasses appear as separated jigsaw pieces with their complementary shaped coastlines. One example of this is how the North Western coastline of Africa could quite easily ‘slot into’ the North Eastern Coastline of America. This suggests that in the history of the Earth‚ these two land masses were once connected

propagation in “thin” organs is affected by the mechanical properties of the tissues surrounding those organs. In order to obtain the proper mechanical properties of such boundary sensitive organs‚ an analytical solution for the dispersion curves on a plate surrounded by semi-infinite solids was derived and validated. Keywords — Shear wave; Dispersion Curves; Ultrasound Elastography Introduction Through the last decades the use of Shearwave Dispersion Ultrasound Vibrometry (SDUV) has become a powerful
