Individual solid particles are characterised by their size‚ shape‚ and density. 1.1 Particle shape The shape of an individual particle is expressed in terms of the sphericity F s‚ which is independent of particle size. The sphericity of a particle is the ratio of the surface-volume ratio of a sphere with equal volume as the particle and the surface-volume ratio of the particle. For a spherical particle of diameter D p‚ F s =1; for a non-spherical particle‚ the sphericity is defined as Dp:

risky assets in the optimal portfolio. In the mean-variance analysis‚ we use arithmetic excess returns. Geometric returns are not suitable in a mean-variance framework. The weighted average of geometric returns does not equal the geometric return of a simulated portfolio with the same composition. The observed difference can be explained by the diversification benefits of the portfolio allocation. We derive the arithmetic

The Variation of Yeast Cells When Adding an Antibiotic Biology 1401- A October 21‚ 2013 Abstract. -- The main focus in this experiment was to find out if antibiotics affect yeast cells culture when added. The observation of the two cultures along with the yield of yeast cell reproduction between the two cultures was the sole purpose of the experiment; culture-A (- antibiotic) and culture-B (+ antibiotic). Our hypothesis stated whether antibiotic effects yeast cells cultures. This theory was

Executive summary In this report we focus on Nike’s Inc. Cost of Capital and its financial importance for the company and future investors. The management of Nike Inc. addresses issues both on top-line growth and operating performance. The company’s cost of capital is a critical element in such decisions and it is important to estimate precisely the weighted average cost of capital (WACC). In our analysis‚ we examine why WACC is important in decision making and we show how WACC for Nike Inc. is
