Using Radar Cross-Section To Enhance Situational Awareness Tools For Airport Avian Radars, Tim J. Nohara, Robert C. Beason, Peter Weber

Human–Wildlife Interactions

Digital avian radars can track bird movements continuously in the vicinity of airports without interruption. The result is a wealth of bird-track data that can be used in mitigation efforts to reduce bird strikes on and near airfields. To make the sheer volume of bird track data generated by digital avian radars accessible to users, we developed tools to transform these data into analytical and visualization products to improve situational awareness for wildlife and airfield personnel. In addition to the parameters traditionally associated with radar tracking (latitude, longitude, altitude, speed, and heading), we have implemented a procedure to estimate the …

Factors Affecting White-Tailed Deer-Browsing Rates On Early Growth Stages Of Soybean Crops, Gregory M. Colligan, Jacob L. Bowman, Joseph E. Rogerson, Bruce L. Vasilas Jan 2011

Factors Affecting White-Tailed Deer-Browsing Rates On Early Growth Stages Of Soybean Crops, Gregory M. Colligan, Jacob L. Bowman, Joseph E. Rogerson, Bruce L. Vasilas

Human–Wildlife Interactions

White-tailed deer (Odocoileus virginanus) damage to soybean crops is a concern for soybean producers. Although researchers have documented decreases in the intensity of deer-browse on soybean plants as the growing season progresses, an understanding of the mechanisms driving the decrease in deer-browse is necessary for reduction and mitigation of deer damage to soybean crops. We tested 4 hypotheses to determine why deer-browse rates decrease 3 weeks after plant emergence: (1) plant phenology affects plant palatability; (2) diet change occurs; (3) deer damage induces a plant response making soybean leaves less palatable: and (4) deer consume fewer leaves but …

Comparison Of The Anticoagulant Response Of A Novel Fluorogenic Anti-Fxa Assay Wth Two Commercial Anti-Fxa Chromogenic Assays, Leanne F. Harris, Aoife O'Brien, Vanessa Castro-Lopez, James S. O'Donnell, Anthony J. Killard

Articles

Introduction: Fast and accurate monitoring is crucial in the successful regulation of coagulation therapy. For the treatment of venous thromboembolism, both unfractionated heparin (UFH) and low molecular weight heparins (LMWH) are commonly administered. The chromogenic anti-factor Xa (FXa) assay is currently considered the ‘gold standard’ assay for monitoring LMWH. However different commercial chromogenic methods often differ when tested with the same samples. Fluorogenic anti-FXa assays have the potential to offer greater benefits over chromogenic assays in terms of greater specificity, sensitivity and they are not so influenced by sample opacity or turbidity. Materials and Methods: Commercial plasmas were spiked with …
