Agenda: A Life Of Contributions For All Time: Symposium In Honor Of David H. Getches, University Of Colorado Boulder. School Of Law, University Of Colorado Law Review

A Life of Contributions for All Time: Symposium in Honor of David H. Getches (April 26-27)

On April 26-27, 2012, Colorado Law honored David H. Getches with a symposium to celebrate his life and legacy of trailblazing scholarship. “A Life of Contributions for All Time” featured a keynote address by Distinguished Professor Charles Wilkinson entitled, “Hero for the People, Hero for the Land and Water: Reflections on the Enduring Contributions of David Getches.” Top scholars in the fields of natural resources, water, and American Indian law reflected on Dean Getches’ contributions and their own insights into these fields, including Professor John Leshy, John Echohawk, Professor Carole Goldberg, Professor Joe Sax, Professor Rebecca Tsosie, Justice Greg Hobbs, …

[1] The goal of this study is to determine how H2O and HDO measurements in water vapor can be used to detect and diagnose biases in the representation of processes controlling tropospheric humidity in atmospheric general circulation models (GCMs). We analyze a large number of isotopic data sets (four satellite, sixteen ground-based remote-sensing, five surface in situ and three aircraft data sets) that are sensitive to different altitudes throughout the free troposphere. Despite significant differences between data sets, we identify some observed HDO/H2O characteristics that are robust across data sets and that can be used to evaluate models. We evaluate …

Question: Climate change processes could influence the dynamics of biotic interactions such as plant competition, especially in response to disturbance phenomena such as invasional processes. Are competitive effects of native species on an invadermediated bywater availability?

Location: Glasshouse facility, New SouthWales, Australia.

Methods: We constructed competitive hierarchies for a representative suite of species from coastal dune communities that have been invaded by the Asteraceae shrub, bitou (Chrysanthemoides monilifera subsp. rotundata). We used a comparative phytometer approach, where the invader species was grown with or without a suite of native species in glasshouse trials. This was used to construct competition hierarchies …

Synthesis, Properties And Water Permeability Of Swnt Buckypapers, L J. Sweetman, L Nghiem, I Chironi, G Triani, Marc In Het Panhuis, St F. Ralph

The ability of macrocyclic ligands to facilitate formation of dispersions of single-walled carbon nanotubes (SWNTs) was investigated using a combination of absorption spectrophotometry and optical microscopy. Vacuum filtration of aqueous dispersions containing SWNTs and various macrocyclic ligands (derivatised porphyrin, phthalocyanine, cyclodextrin and calixarene) afforded self-supporting membranes known as buckypapers. Microanalytical data and energy dispersive X-ray spectra were obtained for these buckypapers and provided evidence for retention of the macrocyclic ligands within the structure of the membranes. The electrical conductivities of the membranes varied between 30 ± 20 and 220 ± 60 S cm−1, while contact angle analysis revealed they all …
