Simulation of the Coiling of a polymer strand Tsvetoslav Pavlov Department of Materials‚ Imperial College London‚ United Kingdom 27th Feb 2012 1. Abstract This study will examine the temperature dependence of internal energy‚ heat capacity and R2 value (representative of the end to end distance) using a Langevin Dynamics simulation. It will also consider the dependence of the internal energy‚ heat capacity and R2 value with increasing polymer chain length. Internal energy has been found

Chapter 11 Questions to be graded: 5. Were the experimental and control groups similar in their type of feeding? Provide a rationale for your answer. Answer: Yes the experimental and control groups are similar in their feeding type because 40.6% in the experimental group decided to breast-feed‚ and 41.7% in the control group decided to breast-feed‚ that’s only 1.1% difference. 53.1% of the experimental group bottle-fed while 50.0% of the control group bottle-fed‚ a small 3.1% difference.
