Analysing the Effects of Excise Taxes Using Microsoft Excel

This paper examines the effects of an excise tax imposed on a monopolist's product. Then simple but quite general polynomial demand and cost curves are introduced and discussed, as is the Microsoft Excel workbook that embeds the functions. Finally, exercises based on selected special cases illustrating the use of the workbook are sketched.

Development of a rotary fluid transfer coupling and support mechanism for space station

A design was developed for a rotary fluid coupling to transfer coolant fluids (primarily anhydrous ammonia) across rotating joints of the space station. Development testing using three conceptual designs yielded data which were used to establish the design of a multipass fluid coupling capable of handling three fluid circuits. In addition, a mechanism to support the fluid coupling and allow an astronaut to replace the coupling quickly and easily was designed

Investigating Schedule Length of Space and Missile Systems Center Contracts

Acquisition reform has long been the goal of the Department of Defense to save, recover and redistribute funds in an efficient manner. The Space and Missile Systems Center Program Management and Integration Directorate (SMC/PI) and Acquisitions Center of Excellence (ACE) have shared the same effort and have made strides to better their acquisition processes. Many different angles have been examined to try to discover cost and schedule growth however, little research has been done to find the drivers of schedule length. This research is aimed at finding contributing factors to the length of schedule of the pre-acquisition process. By using Fisher’s Exact test and contingency table analysis programs were explored to find what factors contribute to the length of schedule. The results of this analysis show significance can be found in the contract’s type, strategy and the phases in which a program is in. Additionally, the research shows significance with programs that waive stages

Effects of Using Canola Meal as a Protein Source in Broiler Diets

Six experiments were conducted to evaluate the response of broilers fed canola meal. Experiment 1 assessed performance and carcass yields when broilers were fed various combinations of canola and soybean meal in nutritionally balanced diets based on digestible amino acid values. The results suggested that canola meal can be used in isocaloric diets as a partial replacement for Soybean meal. Experiment 2 assessed broiler performance and carcass yields when using various levels of canola meal in broiler diets with a constant level of supplemental poultry oil. The resulting data suggested when diets are formulated with a constant level of supplemental fat; the level of CM should not exceed 10%. Experiment 3 and 4 were conducted simultaneously which examined two diet types Corn-Soy (CS), Corn-Soy-Canola (CSC) and four amino acid (AA) levels (80, 85, 90, and 95% of suggested level). ProAct and Cibenza protease enzymes were added at 3 different levels (0, 1, and 2 times suggested amount). The resulting data suggested performance for birds fed incrementally higher percentages of AA and the CSC improved. The addition of enzymes did not significantly improve BW. However, the addition of ProAct at 2 times suggested level improved FCR within the three-way interaction. Experiment 5 was conducted to evaluate pellet quality, broiler performance, and carcass characteristics of birds fed diet combinations of DDGS, SBM, and CM. These results concluded that 15 % DDGS and 20% CM can be used in combination without significantly affecting pellet quality. However, performance and parts yield displayed undesirable characteristics. Experiment 6 was conducted using two diet types; isocaloric and optimum nutrient density, two amounts of DDGS (0 and 15%) and six levels of canola meal (CM) (0, 5, 10, 15, 20, and 25%). The resulting data suggest if diets are maintained isocalorically any combinations of ≤ 15% DDGS and ≤ 25% CM without significantly decreasing performance. If diets are maintained at optimum nutrient density and 15% DDGS, CM can be added at 10, 15 and 20% levels without depressing BW or FCR. However, if diets are maintained at optimum nutrient density and 0% DDGS are added, CM cannot be added without depressing BW
