A method for determining the optimum rate of soil erosion


, : A method for determining the optimum rate of soil erosion. Agricultural Economics Research Report, Department of Agricultural Economics, University of Illinois (161): 29

A mathematical programming model is used to determine the optimum rate of soil erosion in the Big Blue Watershed, Pike County, Illinois. The nonlinear criterion function used to select the optimum soil loss is a function of the sum of the discounted economic surpluses minus a sediment damage and minus a penalty reflecting losses beyond the planning period of 48 years.

A retained rear tip extender remains a challenge in penile prosthetic explantation. Removal failure can compromise the success of the new implant. We report a novel method of removing a retained rear tip extender using a Brook's dilator.
