Pumping Plant Performance

Irrigation accounts for a large portion of the energy used in Nebraska agriculture. This paper describes a method to estimate the cost of pumping water and compares the amount of energy used by a properly designed and well-maintained pumping plant, represented by the Nebraska Pumping Plant Performance Criteria (NPPPC). The results can help determine the feasibility of repairing the pumping plant. Methods to compare energy sources are also presented. We recommend that you periodically arrange with a well drilling company to test the efficiency of your pump. Worksheets for pumping plant performance are included in the appendix

Reducing the cost of pumping irrigation water

Irrigation accounts for a large portion of the energy used in Nebraska agriculture. The cost to pump irrigation water depends on the type of energy used to power the pumping unit. This document describes a method to estimate the cost of pumping water and to compare the amount of energy used to that for a well maintained and designed pumping plant. The results can help determine the feasibility of repairing the pumping plant

Planar and Three-Dimensional Printing of Conductive Inks

Printed electronics rely on low-cost, large-area fabrication routes to create flexible or multidimensional electronic, optoelectronic, and biomedical devices1-3. In this paper, we focus on one- (1D), two- (2D), and three-dimensional (3D) printing of conductive metallic inks in the form of flexible, stretchable, and spanning microelectrodes

Salience games : private politics when public attention is limited

We develop a theoretical model in which an industry and NGO play salience games - they act strategically to influence public attention to social impacts in the sector. Salience stimulates extra donations for the NGO, and thus firms have incentives to hide the damage they do to avoid public attention. How can an NGO design its mission (how to divide income between campaigning and other projects, and what sorts of campaigns to run) to thrive in such a setting? We show that when public attention is scarce, a greater campaign orientation induces industry to invest in greater obfuscation, starving the NGO of funds. The NGO in turn strategically biases its mission away from campaigns, and in favor of sector-wide versus firm-specific campaigns, but not by as much as a welfare-motivated planner would want. When public attention is avoided by a mixture of substantive and symbolic action, we show that a greater weight on the former induces the NGO to become more campaign-oriented, with social damage lower
