Extraction and Quantitative Determination of B-Carotene Introduction The study of B-Carotene is important because it is good for vision‚ immunity‚ and overall health. The purpose of this experiment is to extract and find quantitative amount of Beta-carotene from a carrot sample. The raw product(carrots) was extracted using simple distillation. The purity of the product will be characterized using percent yield‚ thin layer chromatography‚ Beer’s Law‚ and UV-vis. Beer’s law is used because in this

The History Of Beta The year of 1934 was the year that saw many exciting events and changes throughout the world… The Dionne sisters (the first quintuplets to survive birth) were born in Canada‚ The St. Louis Cardinals defeated the Detroit Lions for the World Series‚ Vitamin K was discovered by Henrik Dam‚ and a first class stamp cost $0.03‚ but the most exciting event by far happened when the National Beta Club began as the dream of Dr. John W.

Part 1 ’’ A Measurement of Risk 1.1 Risk 1.2 Capital Asset Pricing Model The estimation of systematic risk (or ‘beta’) is central to the implementation of the capital asset pricing model (CAPM) for researchers and practitioners. Markowitz (1952) argued that investors should be concerned with holding efficient portfolios‚ that is‚ a portfolio offering the highest expected return for each level of risk. Sharpe (1964) and Lintner (1965) took Markowitz’s work one step further to develop the CAPM

Mean-Variance Analysis Mean-variance portfolio theory is based on the idea that the value of investment opportunities can be meaningfully measured in terms of mean return and variance of return. Markowitz called this approach to portfolio formation mean-variance analysis. Mean-variance analysis is based on the following assumptions: 1. All investors are risk averse; they prefer less risk to more for the same level of expected return. 2. Expected returns for all assets are known. 3. The

Calculating Beta for Compuware Corporation Financial websites tend to calculate beta on securities differently for publicly traded companies. Beta is merely an estimable measure of an assets’ risk in relation to the market. Because each website has their own underlying assumptions‚ they compute beta to have different values. In some cases‚ the variance in beta is as large as 0.50. To find out what underlying assumptions websites used to compute their betas‚ we performed a series of regression
