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

BETA MANAGEMENT COMPANY Q1. Calculate the variability (standard deviation) of the stock returns of California REIT and Brown Group during the past 2 years. How variable are they compared with Vanguard Index 500 Trust? Which stock appears to be riskiest? The stock returns for each month are given in Table 1. Based on the monthly returns‚ the standard deviation or variability of each stock has been calculated. The standard deviation for California REIT is 9.23% and the standard deviation for Brown

Question 4: To compute Beta‚ it follows the formula | California REIT | Grown Group | Beta | 0.14 | 1.16 | The result is consistent with question 3. The Grown Group stock has a higher beta so it is riskier. It is more sensitive to the market factor. Question 5: The Grown Group stock should have a higher expected return because it

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

Diabetes Beta- carotene is an organic compound categorized as a terpenoid (Gutiérrez‚ & Gonzalez‚ 2010). Naturally‚ it is a predecessor of vitamin A‚ and found in several yellow fruits and vegetables. These organic nutrients play a vital role in aiding vision‚ skin growth‚ and bone development. In addition to these crucial roles‚ Beta-carotene may be of significant help in regulating the blood sugar in diabetic persons (Gutiérrez‚ & Gonzalez‚ 2010). Human bodies regulate blood sugar levels with

How to Calculate Beta Beta refers to the volatility of a particular stock compared against the volatility of the entire stock market or‚ in practice‚ a representative index of that market‚ such as the Standard and Poor ’s (S&P) 500. Beta is an indicator of how risky a particular stock is and is used to evaluate its expected rate of return. Beta is one of the fundamentals stock analysts consider when choosing stocks for their portfolios‚ along with price-to-earnings ratio‚ shareholder ’s equity

Angiotensin-II Receptor Blockers (ARBs): ARBs are a class of drugs that halt the action of Angiotensin-II by blocking the binding between Angiotensin-II and Angiotensin-II receptors. This leads to reduced blood pressure as the blood vessels get dilated. This reduced blood pressure helps to ease heart failure as it now becomes easier for the heart to pump this blood. Commonly used ARBs are Irbesartan‚ candesartan‚ Losartan‚ Olmesartan‚ Telmisartan‚ valsartan‚ and azilsartan. Mechanism Angiotensin-II
