Computational Chemistry: Conformational Analysis of Ethane and Butane Objectives: To visualize molecules in 3-dimensions. To learn how to use the Spartan ES software. To compute and graph the relative conformational energies of ethane and butane. Background: One of the most successful theories of the 20th century is quantum mechanics‚ also called wave mechanics. The idea that energy in atoms occurs in discrete bundles is contrary to our everyday notion that energy flows smoothly into or

1. Calculation of APS for National Senior Certificate (NSC‐Deg) results The values allocated to the classes of performance‚ i.e. 1 ‐ 7 will be added to calculate the composite Academic Performance Score (APS). Life Orientation (LO) will not be included in the APS calculation (no points will be allocated for LO). The Academic Performance Score (APS) will be calculated by adding the performance ratings of the other 6 subjects. UKZN will recognize academic excellence

Christine Woelfel-Monsivais 10/13/14 Chem 4448.13 Lab 4: Gaussian Calculations Introduction The purpose of the lab was to gain a better understanding of the Gaussian calculations and see how the obtained calculations can be used to explore the chemistry of the atoms. In this lab several molecules were created and given specific bond lengths before running a Gaussian test for optimization and frequency. Through this test the vibrational frequency‚ force constant‚ reduced mass and point group were

heavier workloads‚ which heightened concern about the adequacy of staffing levels in hospitals” (JONA‚ 2000). Therefore the most important task is to calculate the number of nurses required for each unit. The following text describes the appropriate calculation necessary to determine the number of nurses on a hypothetical unit that has 50 beds and is a Medical-Surgical patient population with an average daily census of 45 patients. There are 45 patients that require 4 nursing hours per nurse per day

Joanna began her calculation of Nike’s WACC by finding the necessary weights of debt and equity to be used. To begin‚ Joanna found Nike’s debt by combining the book values of current long-term debt‚ notes payable‚ and long-term debt‚ which were all found on Nike’s balance sheet. The values were $5.4 million‚ $855.3 million‚ and $435.9 million respectively. This calculation gave Nike a total debt of $1‚296.9 million. To find Nike’s equity‚ Joanna used the book value of total shareholders’ equity

Case 17 – The Investment Detective The case of the Investment Detective laid out the cash flows for us in each of eight different projects. Before doing any calculations we came up with the assumption that we could not rank the projects simply by inspecting the cash flows. Without the ability to rank the projects based off of cash flows solely‚ we had to use some analytical criteria as a capital budgeting analyst to provide some thorough support and reasoning for how we ranked the four best
