Measurement of Condensed Water Content in Liquid and Ice Clouds Using an Airborne Counterflow Virtual Impactor

Creator:: Twohy, Cynthia, Schanot, Allen J., and Cooper, William A.
Abstract:: Condensed water content (CWC) measured using a counterflow virtual impactor (CVI) with a Lyman-α hygrometer downstream is compared with that measured by other airborne instruments (a hot-wire probe, a PMS FSSP, and a PMS 2D-C). Results indicate that the CVI system provides a reliable measurement of CWC in both liquid-...

Heavy fermion effective mass in the superconducting vortex state

Creator:: Townsend, Emily A.
Abstract:: The extended-Lifshitz-Kosevitch formalism (ELK) unifies the treatment of the de Haas-van Alphen (dHvA) effect, allowing it to transcend its traditional roles of mapping Fermi surfaces and measuring effective masses. Here we exploit the capabilities of dHvA as a probe of many-body effects to examine heavy-fermion su- perconductivity. ELK successfully describes...

A study on the effects of enhanced pCO2 on open ocean diazotrophic assemblages

Creator:: Gradoville, Mary Rose
Abstract:: Biological di-nitrogen (N₂) fixation is a key process in open-ocean ecosystems, where the new nitrogen (N) provided by marine diazotrophs can support a large fraction of primary productivity and carbon (C) drawdown. Recent laboratory studies have shown that elevated pCO₂ enhances the rate of N₂ fixation by select laboratory isolates...
