A Quantitative Model of the Initiation of DNA Replication in Saccharomyces cerevisiae
(University of Waterloo, 2012-05-01)A crucial step in eukaryotic cell proliferation is the initiation of DNA replication, a tightly regulated process mediated by a multitude of protein factors. In Saccharomyces cerevisiae, this occurs as a result of the ... -
Quantitative modeling of nitrogen cycling along the river continuum: streambed sediments, reservoirs, and isotopes
(University of Waterloo, 2018-09-26)The vast release of anthropogenically produced reactive nitrogen (N) into the environment, by agricultural activities, energy production and municipal wastewater, has led to a variety of consequences for atmospheric, ... -
Quantitative Modelling of the Shifts and Splitting in the IR Spectra of SF<sub>6</sub> in an Ar Matrix
(University of Waterloo, 2005)An infrared active polyatomic molecule has several vibrational modes, each of which has a characteristic frequency. If the molecule is trapped in a matrix of perturbing atoms, those vibrational frequencies will shift, ... -
Quantitative Optical Gas Imaging using Broadband Mid-wavelength Infrared Single-Channel and Multispectral Cameras
(University of Waterloo, 2022-11-25)Quantifying and limiting methane emissions from upstream oil and gas is an efficient strategy to reduce anthropogenic climate change and has received considerable attention from regulators in recent years. Quantification ... -
