Determining the habitat occupancy of young of year Arctic Grayling (Thymallus arcticus) in sub-Arctic tundra streams while accounting for imperfect detection
(University of Waterloo, 2016-01-22)I developed multi-state, multi season occupancy models to determine how a number of interacting ecological variables influence the occurrence of young-of-year (YOY) Arctic Grayling (Thymallus arcticus) in nine streams on ... -
Determining the native and nonnative effects of myristoylation on the folding and switching of hisactophilin
(University of Waterloo, 2012-09-26)Myristoylation, the covalent linkage of a C14 saturated fatty acyl chain to the N-terminal glycine in a protein, plays an important role in reversible membrane and protein binding in cellular signaling by the modified ... -
Determining the relationships between forage use, climate and nutritional status of barren ground caribou, Rangifer tarandus groenlandicus, on Southampton Island, Nunavut, using stable isotopes analysis of d 13C and d 15N
(University of Waterloo, 2006)The caribou (Rangifer tarandus groenlandicus) on Southampton Island, Nunavut, Canada for the years 1998-2000 and 2004, 2005, were investigated using stable isotope analysis (SIA) of carbon (d 13C) and nitrogen (d 15N). ... -
Determining the Structures and Properties of Biologically-relevant Ions
(University of Waterloo, 2018-08-09)Gas phase studies of biologically relevant ions are increasing in popularity due to the possibility of high throughput analysis requiring minimum sample concentrations. This thesis explores the potential of differential ... -
Determining the subcellular localization of adenosine kinase and SAH hydrolase and their roles in adenosine metabolism
(University of Waterloo, 2007-01-23)Housekeeping enzymes are vital to the metabolism of all plant cells. Two such enzymes adenosine kinase (ADK) and S-adenosylhomocysteine (SAH) hydrolase share a similar function: both sustain S-adenosylmethionine-dependent ... -
Developing a Generalized Model for Neutron Diffraction with Quantum Information Theory
(University of Waterloo, 2022-08-31)Due to their high mass and neutral electric charge, neutrons are often used at low energies to probe small-scale structures or measure fundamental constants of nature. To design neutron optical elements for use in these ... -
