A Predictive-Adaptive, Multipoint Feedback Controller For Local Heat Therapy Of Solid Tumors, Charles F. Babbs, V A. Vanguine, J T. Jones

Weldon School of Biomedical Engineering Faculty Publications

Uniform heating of tumor tissue to therapeutic temperatures without damaging surrounding normal tissue is required for optimal local heat therapy of cancer. This paper describes an algorithm for online computer control that will allow the therapist to minimize the standard deviation of measured intratumoral temperatures. The method is applicable to systems incorporating multiple surface and/or interstitial applicators delivering microwave, radiofrequency, or ultrasonic power and operating under the control of a small computer. The essential element is a novel predictive-adaptive control algorithm that infers relevant thermal parameters from the responses of multiple temperature sensors, as each of the power applicators is …

Clostridium Perfringens: An Adjunctive Indicator In Nonpoint Pollution, Steven G. Eberl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Clostridium perfringens (CP) was evaluated as an additional indicator in assessing impacts and sources of microbial pollution in the Idaho-Utah Cache Valley. Point, nonpoint, river water, and animal fecal samples were analyzed for CP, total coliforms, fecal collforms, and fecal streptococci.

Monthly river samples consistently contained < 20 CP/100 mL, but concentrations of the other indicators varied significantly by location and date. Two sample stations consistently had CP concentrations greater than 20/100 mL. One of these stations was influenced by an upstream wastewater discharge. Chlorinated effluent from this trickling filter plant contained greater than 10³ CP/100 mL, but met a 400 FC/100 mL discharge standard. A consistent decrease in CP concentrations in samples taken downstream from this wastewater source were found, despite significant impact from adjacent nonpoint pollution. Lagoon and oxidation ditch wastewater effluents sampled contained < 20 CP/100 mL.

Nonpoint sources sampled (e.g., cattle feedlot runoff) contained < 20 CP/100 mL and 10²-10⁴/100 …

A three-dimensional finite element model of a tibial shaft is automatically generated from the CT file by a pre-processing procedure for a finite element program. The developed pre-processor includes an edge detection algorithm which determines the boundaries of the reconstructed cross-sectional images of the scanned bone. A mesh generation procedure then automatically generates …

Tillage Systems For Row Crop Production, Elbert C. Dickey, Paul J. Jasa, Alice J. Jones, David P. Shelton

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Selecting the tillage system best suited to a particular farming situation is an important management decision. Formerly, the traditional system was a moldboard plow operation followed by several secondary tillage operations before planting. This system can be appropriate for poorly drained soils having little or no slope and low erosion potential. However, plowing has several disadvantages . The potential for soil erosion is high on sloping lands, and labor and fuel requirements can be substantially higher than with other tillage and planting systems.

Today, conservation tillage systems are used to reduce preplant tillage operations, thus reducing soil erosion and moisture …

The Effect Of Detention Period On The Clarification Efficiency Of Nitrified Activated Sludge, James C. Boyd

Retrospective Theses and Dissertations

Proper performance of the final clarifier in the activated sludge process is vital to total system efficiency. Inadequate clarification can adversely affect substrate removal efficiency due to the biochemical oxygen demand exerted by solids lost in the clarifier effluent. Detention period is one factor which influences clarification performance and thus is of interest to the designer engineer. Also of interest is the relationship between detention period and rising sludge conditions in the clarifier, which can lead to a deterioration in clarification efficiency. Rising Sludge conditions are believed to be caused by the denitrification of nitrified activated sludge in the final …

Quinoline Sorption To Subsurface Materials: Role Of Ph And Retention Of The Organic Cation, John M. Zachara, Calvin Alnsworth, Larry Felice, Charles Resch

United States Department of Energy: Publications

The sorption of quinoline (pK_a = 4.94) was investigated on low-organic-carbon subsurface materials that varied in pH. Sorption isotherms were measured from 10^-7 to 10^-4 M quinoline and were found to be nonlinear. The resulting Freundlich constants (K_F), based on total aqueous quinoline concentration, were poorly correlated with subsoil properties, including organic carbon. Higher sorption in the acidic subsoils and favorable coefficents for regression of K_F, normalized to cation-exchange capacity vs. the ionization fraction (Q), point to the importance of ion exchange of the protonated compound. When the subsoil pH …
