SEMINAR 4: FRIDAY 7th NOVEMBER 2014 ASSET PRICING Seminar Questions to be completed before class 1. Explain‚ using examples the difference between systematic risk and unsystematic risk. 2. Why is it useful to calculate returns on assets using either a one-factor model such as‚ CAPM or a multi-factor model such as‚ APT? 3. Answer questions 8 and 10 on page 316 of the Hillier et al. (2013) text. 4. Multifactor Model The monthly return on an asset‚ Rs is determined by the following equation: Rs = 0

Because it is subjective‚ based on opinions‚ no CBA‚ and no real standards. 3. What was your rationale in assigning “1” risk impact / risk factor value of “Critical” for an identified risk‚ threat‚ or vulnerability? Because it was the most serious risk. 4. When you assemble all of the “1” and “2” and “3” risk impact/risk factor values to the identified risk‚ threats‚ and vulnerabilities‚ how did you prioritize the “1”‚ “2”‚ and “3” risk elements? What would you say to the executive management in regards

HINTS ON WRITING YOUR REPORT Title: Enzyme activity Objective: To investigate the effect of temperature on amylase activity Design principle Background: Amylase activity products? (show the equation) Which factors will affect enzyme activity? How to study the rate of reaction? (e.g. rate of disappearance of substrates or rate of formation of products) Independent variable: temperature of reaction mixture or at which the enzymatic reaction occurs. It can be varied by setting water bath at

Biology Enzyme Catalase Investigation Aim: The aim of this investigation is to study and observe whether or not the concentration of hydrogen peroxide (varying from 10 – 30 millilitres) affects the rate of reaction. Hypothesis: With the increase of the concentration of Hydrogen Peroxide 3% substrate‚ I prediction that the rate of pressure increase will begin to amplify. The pressure is bound to increase because the catalase quickly reacts with the hydrogen peroxide; this is why the more substrate

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

Drew Staples 6/12/14 Properties of water Question Does mixing water with other substances change it’s boiling point. Research The boiling point of a liquid is when the temperature causes the vapor pressure to be equal to the air. Air density will change waters boiling point. High altitudes give water a lower boiling point. Hypothesis If the water is less dense then it will boil faster and the boiling point will be lower.

Name: Mugabe Rodrigue Class: Grade 11B Subject: Biology Topic: DNA Extraction From Onion Date: 20/1/2014 Introduction: DNA‚ or deoxyribonucleic acid‚ is the hereditary material in organisms. Nearly every cell in an organism has the same DNA. Most DNA is located in the cell nucleus.The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of these bases determines the information available for

the outcome of enzyme activity Introduction In this project I will monitor the rate of activity of Catalase. Catalase is an Enzyme which in the right conditions catalyses the decomposition of Hydrogen Peroxide into water and oxygen; 2H2O2 + Catalase >>> 2H2O + O2 Catalase is found in all cells and protects them from Hydrogen Peroxide which is a dangerous waste product that needs to be eliminated. Without Catalase living things could not survive. What are Enzymes? Enzymes are found in the
