We present quantitative measurements of time-dependent flagellar waveforms for freely swimming biflagellated algal cells, for both synchronous and asynchronous beating. We use the waveforms in conjunction with resistive force theory as well as a singularity method to predict a cell's time-dependent velocity for comparison with experiments. While net propulsion is thought to arise from asymmetry...

In this study, we analyze an inventory system facing stochastic external demands and an autonomous supply (independent return flow) in the presence of fixed disposal costs and positive lead times under a continuous review replenishment– disposal policy. We derive the analytical expressions of the operating characteristics of the system; and, construct the objective function to minimize the tota...

A significant amount of non-compliance with the personal income tax is due to individuals who have not filed a tax return and so who are not “in the system”. We use experimental laboratory methods to examine the effect of positive inducements for filing a tax return. Our design captures the essential features of a voluntary income reporting and tax assessment system: human participants earn inc...

Traditional accounting techniques such as return on investment and net present value are often used when deciding investments in information technology. We examined both academic and trade literature to determine the utility of such techniques and to recognize alternatives. Findings reveal that this survey is needed and is important for information systems managers facing heightened scrutiny of...

Closed-end funds have been a topic of interest among academics and professionals on five counts. First, they tend to sell above their net asset value at their commencement. Second, they start selling at a discount within a year. Third, this discount is volatile but mean-reverting. Fourth, the news of open-ending a fund reduces the discount although some discount persists till the actual event o...

The cost and return analysis of different sizes of broiler farms in the Punjab state has been carried out based on the primary data collected from 140 broiler farmers for the period March 2008 to February 2009 in three districts, viz. Ludhiana, Hoshiarpur and Muktsar. The study has shown that the total fixed investments per bird have been highest on small farms, followed by medium and large far...

This study was performed to determine the feasibility of integrating a full offset solar power unit at Cal Poly’s dairy operation. The dairy is relatively small, with four hundred cows and only two hundred mature milking cows. The dairy’s average annual electricity use is approximately 330,000-kilowatt hours. Based on the size and annual electricity demand, REC Solar, a local solar power compan...

Soybean aphid, Aphis glycines Matsumura, is a major invasive pest that has caused substantial yield loss and increased insecticide use in the United States since its discovery in 2000. Using the economic surplus approach, we estimate the economic benefits of U.S. research and outreach for integrated pest management (IPM) of soybean aphid. We calculate ex ante net benefits from adoption of an IP...

Steer progeny (n = 80) produced by mating British crossbred females to one of three terminal (Charolais) sires or one of five maternal (Angus or Red Angus-Composite) sires were evaluated from birth to harvest to compare the effects of sire type (terminal vs. maternal) on growth performance, carcass characteristics, and net return per head. Steers sired by terminal bulls were heavier (P < 0.05) ...
