Isokinetic dynamometry testing on male university sport and exercise science students looking at Hamstring/Quadriceps ratio‚ peak torque‚ peak torque to body mass ratio and power. Abstract Isokinteic dynamometry testing is important in monitoring injury and performance. There are few studies that have looked at male university sport and exercise science students bilateral difference of the hamstrings and quadriceps at 60˚s and 180˚s.The purpose of the study was to look at injury and performance

Kinetic Expressions (Kinetics) has been taking place at Berea College for 20 years. This year the team celebrated its 20th by revisiting a choreography that was performed at the first Kinetics and were very purposeful of who they allowed to choreograph in this production. This will be a critique of some of the dances performed; it will go into detail about each dance‚ analyze the movements and reveal the message. The opening act to Kinetics this year was the choreography that was performed at

Kinetic energy is increasing between letters A-B‚ C-D and E-F. Based off the observations‚ in phase A-B Tert-Butyl Alcohol stays a solid‚ in phase C-D Tert-Butyl Alcohol stays a liquid‚ and in phase E-F the chemical stays a gas. This is observed at the particle level because temperature is a measure of Ek; the temperature is increasing which increases kinetic energy. Since Ek is the energy of motion‚ the particles would increase their velocity and the number and force of collisions. However‚ the

EXPERIMENT-3 CHEMICAL KINETICS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will study the rate of decomposition of hydrogen peroxide to form oxygen according to the net equation: 2H2O2 (aq) 2H2O(l) + O2 by measuring the rate at which oxygen evolved‚ we will investigate how the rate changes with varying initial concentrations of hydrogen peroxide and iodide catalyst. After we will study

around 15mins. After first centrifuge the solution came out pale orange. The second heat and centrifuge produced very little precipitate. |The orange colour in the solution may indicate a presence of Cadmium (Cd2+) Most of the Group 2 ions in solution were precipitated out in reaction. Nearly complete reaction was obtained. | |2-3 Separation and Detection of Bismuth |After heating with HNO3 added a yellow gelatinous substance appeared. After NH3 was added to create a basic solution

Chemical Kinetic Models Simplified Global Chemical Kinetic Model In order to compare the two reactors used in our experiment‚ a simplified global kinetic model was used to describe the DRM reaction behavior in different plasma reactor. This model was already used by authors in the field of pollutant removal by using a plasma reactor [15‚ 21–23]. It is generally accepted that free radical processes are the main mechanisms in non-equilibrium plasma reaction [21‚ 24-25]. The chemical kinetics model

The goal for our lab activity was to make a silver mirror by reducing silver ions with dextrose. The materials that we used were acetone‚ 5 mL of 1.5 M ammonium nitrate solution (NH4NO3)‚ 5 mL of 0.5 silver nitrate solution (AgNO3)‚ 10 mL of 5% dextrose solution (C6H12O6)‚ 10mL of 10% sodium hydroxide solution (NaOH)‚ a 50 mL beaker‚ a 250 mL Florence flask with a rubber stopper‚ a 10 mL graduated cylinder‚ a waste beaker‚ and distilled water. The first thing we did was rinsed the beaker‚ cylinder

Unit 11: Kinetics and Equilibrium Activated complex: an intermediate state that is formed during the conversion of reactants into products‚ the structure that results at the maximum energy point along the reaction path. Activation energy: a chemical reaction is the difference between the energy of the activated complex and the energy of the reactants. Catalyst: substance that increases the rate of a chemical reaction by reducing the activation energy‚ but which is left unchanged by the reaction

Effect of ions on living organisms (24 marks) An ion is a charged atom or molecule. This is because it does not have an equal amount of protons and electrons‚ therefore giving the atom an overall charge. An example of an ion is ‚ this is sodium and the plus sign represents an overall positive charge. Ions are very important to living organisms as they are essential for life‚ they play an important role within the cell allowing mechanisms within the living organisms such as respiration‚ to take
