High-Resolution Geophysical Characterization of an Ethanol Release into an Existing Gasoline-Impacted Zone
(University of Waterloo, 2012-04-09)This study aims to evaluate the ability of high-frequency (450 and 900 MHz) ground-penetrating radar (GPR) to monitor the effects of an ethanol release over an existing gasoline-contaminated zone. In September 2009, 184L ... -
A High-Resolution Hydrodynamic Investigation of Brown Trout (Salmo trutta) and Rainbow Trout (Oncorhynchus mykiss) Redds
(University of Waterloo, 2009-04-28)High-resolution velocity measurements were undertaken over a series of redds and riffles on a gravel-bed stream to quantify the hydrodynamics preferred by spawning brown trout (Salmo trutta) and rainbow trout (Oncorhynchus ... -
High-resolution infrared emission spectroscopy of diatomic and triatomic metal hydrides
(University of Waterloo, 2006)Several hydrides of Group 2 and 12 elements were generated in the gas phase using an emission source that combines an electrical discharge with a high temperature furnace, and their high-resolution infrared emission spectra ... -
High-resolution laboratory spectroscopy of transient metal-containing molecules
(University of Waterloo, 2007-05-14)Ten gaseous transient metal-containing molecules have been synthesized and studied by high resolution spectroscopy. Transient molecules are molecules with a short lifetime, and they play an important role in chemistry ... -
High-Resolution Numerical Simulations of Wind-Driven Gyres
(University of Waterloo, 2011-08-26)The dynamics of the world's oceans occur at a vast range of length scales. Although there are theories that aid in understanding the dynamics at planetary scales and microscales, the motions in between are still not yet ... -
