Characterization Of General Esterases From Methyl Parathion-Resistant And -Susceptible Populations Of Western Corn Rootworm (Coleoptera: Chrysomelidae), Xuguo Zhou, Michael E. Scharf, Lance J. Meinke, Laurence D. Chandler, Blair D. Siegfried

Department of Entomology: Faculty Publications

A consistent correlation between elevated esterase activity and methyl parathion resistance among Nebraska western corn rootworm, Diabrotica virgifera virgifera LeConte, populations has previously been documented. Characterization of general esterase activity using naphtholic esters as model substrates indicated that differences between resistant and susceptible strains could be maximized by optimizing assay conditions. The optimal conditions identified here were similar to those reported for other insect species. The majority of general esterase activity was found in the cytosolic fractions of resistant populations, whereas the activity was more evenly distributed between cytosolic and mitochondrial/nuclear fractions in the susceptible population. General esterase activity was …

Department of Entomology: Faculty Publications

Field and laboratory studies were conducted in 2000 and 2001 to determine the feasibility of mass marking western corn rootworm adults, Diabrotica virgifera virgifera LeConte, with RbCl in the field. Results showed that application of rubidium (Rb) in solution to both the soil (1 g Rb/plant) and whorl (1 g Rb/plant) of corn plants was optimal for labeling western corn rootworm adults during larval development. Development of larvae on Rb-enriched corn with this technique did not significantly influence adult dry weight or survival. Rb was also highly mobile in the plant. Application of Rb to both the soil and the …

Legislating Morality: The Duty To The Tax System Reconsidered, Watson

Scholarly Works

Four years ago, I presented a paper at a symposium on professionalism jointly sponsored by the University of Kansas Law School and the Kansas Bar Association. That paper espoused the view (contrary to what appears to be the popular view among tax scholars) that tax lawyers owe no special duty to the "tax system" other than to abide by the law and the applicable standards of professional conduct. During the four-year interim since my last visit to Kansas, however, we have witnessed the deleterious effect of the IRS Restructuring and Reform Act of 1998 (RRA '98) on IRS enforcement and …

Energy Efficient Routing Protocols For Mobile Ad Hoc Networks, Chansu Yu, Ben Lee, Hee Yong Youn

Electrical and Computer Engineering Faculty Publications

Although establishing correct and efficient routes is an important design issue in mobile ad hoc networks (MANETs), a more challenging goal is to provide energy efficient routes because mobile nodes' operation time is the most critical limiting factor. This article surveys and classifies the energy-aware routing protocols proposed for MANETs. They minimize either the active communication energy required to transmit or receive packets or the inactive energy consumed when a mobile node stays idle but listens to the wireless medium for any possible communication requests from other nodes. Transmission power control approach and load distribution approach belong to the former …

Changing Scientific Evidence, Edward K. Cheng

Vanderbilt Law School Faculty Publications

A number of high-profile toxic tort cases, such as silicone breast implants, have followed a familiar and disturbing path: Early studies suggest a link between a suspected substance and a particular illness. Based on these initial studies, lawsuits are brought and juries award large judgments to various plaintiffs. Then later, more comprehensive studies find no evidence of a causal link. How should the legal system cope with this problem in which new scientific evidence calls into question previous findings of liability? These erroneous judgments seriously harm social welfare and legitimacy. Beneficial products are needlessly discontinued or are made more expensive, …
