Beavers (Castor canadensis) can cause dramatic changes in vegetative composition and diversity. Although alterations by beaver have been studied extensively, little attention has been paid to the effects beaver impoundments have on rare plants. Effective conservation of riparian and wetland rare plant species must consider the responses of vegetation to(More)
Wetland destruction has plagued the U.S. for decades, but the need to compensate for these losses has only been embraced within the last 20 years. Because so many compensatory mitigation wetlands have been created, there is a need to assess the function of these valuable ecosystems relative to natural wetlands. The goal of this study was to evaluate the(More)
This research aims to accurately predict and control temperature in real time during the continuous casting of large, semi-finished steel shapes. The approach is to create a fast, accurate transient computer model of heat transfer during the solidification process that serves as a “software sensor”, calibrated in real time through online temperature(More)
The quality of continuous cast steel is greatly affected by fluid flow in the mold region, especially involving transient phenomena and the transport of inclusion particles. As part of a long-term effort to develop and apply comprehensive models of these and other phenomena, this paper reports on studies to evaluate the relative accuracy of models of three(More)
Bioassessment methods for wetlands, and other bodies of water, have been developed worldwide to measure and quantify changes in "biological integrity." These assessments are based on a classification system, meant to ensure appropriate comparisons between wetland types. Using a local site-specific disturbance gradient, we built vegetation indices of(More)

PURPOSE Numerous advances have been made in gene therapy approaches for the treatment of solid tumors, including prostate cancer. While treatment of the primary tumor has been well investigated, little information is available regarding gene therapy techniques which might impact on the progression to metastatic disease. We investigate the ability of p53(More)
