    Phase transfer catalyzed oxidation of cholesterol and related compounds with sodium hypochlorite in ethyl acetate resulted in good to excellent yields of oxidized products. These reactions are mild, eficient, and safe. The ...
  • "Complex variables and conformal mapping applications in fluid flow dynamics" 

    Knodel, Mallory (2005-06-23)
    Transformations in complex analysis can lead to geometric representations of vector fields on the complex plan. These interpretations can be quite helpful in the analysis of functions of complex variables. Many of the ...
  • "Star formation in UV-bright interacting galaxies" 

    Hulsebus, Alan; Nelson, Charles H.; Ragan, Sarah; McGleam, Catherine (2005-06-23)
    The interacting pair NGC3395 and NGC3396 and the interacting trio and NGC3991, NGC3994, and NGC3995 emit strongly in the ultraviolet, indicating multiple regions of active star formation. To investigate the nature of the ...
  • "Faber-Jackson relation in Seyfert galaxies" 

    Bennett, Wendy; Weinzirl, Timothy; Nelson, Charles H. (2005-06-23)
    Previous investigations have indicated that the bulges of Seyfert galaxies are more luminous than those in normal galaxies of the same mass. This may result if Seyfert bulges have experienced recent star formation, perhaps ...
  • "Spectroscopy of star-forming regions in UV bright, interacting starburst galaxies" 

    Frazier, Aaron G.; Nelson, Charles H. (2005-06-23)
    We have obtained long-slit spectroscopy of the star-forming regions in NGC3395, NGC3396, NGC3991, NGC3994, and NGC3995 emit strongly in the ultraviolet, indicating multiple regions of active star formation. To investigate ...
  • "The Effects of methamphetamine and cocaine on rats' Y-Maze performance using directional vs. visual cues" 

    Klipec, William D.; Brackney, Ryan J.; Sounhein, Kyle; Mejia, Rachel; Dolezal, Anna Marie (2005-06-23)
    Two experiments in our laboratory have demonstrated that across a wide range of doses, amphetamine but not cocaine (COC) disrupts the discrimination performance of rats running toward the lighted arm of a Y-Maze. In these ...
  • "Development of the rat P300 ERP during backward chaining" 

    Stanley, Kacey; Lem, Katherine; Klipec, William D. (2005-06-23)
    Several experiments in our laboratory shown P300 amplitude to be an incremental function of proximity to conditioned reinforcers in simple behavioral chains. In this paradigm, one tone predicts lever insertion while a ...
  • "Species traits as predictors of the frequency of recolonization in prairie Lepidoptera" 

    Steichen, Renae M.; Conoan, Christopher J.; Summerville, Keith S. (2005-06-23)
    Restoration ecologists are increasingly turning to the development of models to predict how species move from a regional species pool into a restored community. Two untested assumptions of these models, however, are that ...
  • "The rat P300 ERP to signaled occurrence and omission of expected reinforcers following extended training" 

    Klipec, William D.; Schneider, Brooke; Brackney, Ryan J.; Stanley, Kacey; Schwabe, Jennifer; Young, Bryce (2005-06-23)
    A series of experiments in our laboratory have shown that rat P300 ERP amplitude is an incremental function of conditioned stimulus proximity to primary reinforcement in simple behavioral chains, suggesting that the P300 ...
  • "Do restored wetlands create suitable waterfowl habitat?" 

    Anderson, Scott H.; Summerville, Keith S. (2005-06-23)
    Historically, North American wetland ecosystems supported substantial waterfowl biodiversity prior to agricultural development. Loss of wetland habitats in agricultural states such as Iowa is often linked to regional ...
  • "Indole derivatives interact with DOPC in Langmuir monolayers"
