A body composition model to estimate mammalian energy stores and metabolic rates from body mass and body length, with application to polar bearsDownload
Many species experience large fluctuations in food availability and depend on energy from fat and protein stores for survival, reproduction and growth. Body condition and, more specifically, energy stores thus constitute key variables in the life history of many species. Several indices exist to...
The Na+/H+ exchanger isoform 1 (NHE1) is the predominant isoform in mammalian cells, and regulates intracellular pH and ion concentrations. NHE1 also interacts with numerous proteins and signalling pathways. Consequently, it has been found to influence cell volume, growth, differentiation, and...
Characterization, Structure and Mechanism of Sulfide:quinone oxidoreductase (SQR) from Acidithiobacillus ferrooxidansDownload
A key enzyme in maintaining sulfide homeostasis is the membrane-associated flavoenzyme sulfide:quinone oxidoreductase (SQR) found in nearly all domains of life (except plants). SQR maintains a critical equilibrium between sulfide (H2S, HS- and S2-) and elemental sulfur (S0), coupling the...
Children’s and Fathers’ Perceptions of Fathers’ Use of Structure, Negative Control, and Autonomy SupportDownload
The current study investigated fathers’ and children’s perspectives of fathers’ use of structure, negative control, and autonomy support parenting behaviours in relation to children’s internalizing, externalizing, and adaptive behaviours, and father-child attachment. Researchers interviewed 55...
A study was conducted to evaluate the properties and processes influencing the rate and magnitude of volume decrease and strength gain for oil sand fine tailings resulting from a change in bitumen extraction process (caustic versus non-caustic) and the effect of adding a coagulant to caustic fine...
Over the past fifteen years, a rich program of research has emerged among scholars interested in the role of categories within fields and industries. In this context, studies have shown that categories shape organizational and market processes by grouping firms and products in ways that convey...
Exploration of Microscopic Structure and Dynamics in Halide Perovskite and Perovskite−Inspired Materials with Solid-State NMR SpectroscopyDownload
The work presented in this thesis describes the synthesis, structure, and optical properties of three different classes of halide-based perovskite materials, namely, metal halide perovskites of ABX3 type, halide double perovskites of A2B'B"X6 type, and “vacancy-ordered perovskites” of A2BX6 type...
Sperling, Felix A. H., Murray, Brent W., Li, Yisu, Coltman, David W., Bohlmann, Joerg, Janes, Jasmine K., Cooke, Janice E. K., Boone, Celia K., Huber, Dezene P.W., Keeling, Christopher I., Yuen, Macaire M. S.
The mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins), a major pine forest pest native to western North America, has extended its range north and eastward during an ongoing outbreak. Determining how the MPB has expanded its range to breach putative barriers, whether physical...
Integrating Characteristics of Executive Functions in Non-Demented Aging: Structure, Trajectories, Classification, and Biomarker PredictorsDownload
In aging, executive function (EF) performance (level) and change (trajectory) are linked to multiple interacting risk factors. Structurally, EFs have previously been represented as either a unitary (e.g., unidimensional) or diverse (e.g., multidimensional) set of abilities that change across the...
A fine balance between contraction and relaxation is crucial for the heart to function properly. But often the heart cannot contract with enough force to meet the demands of the body. This condition, called systolic heart failure, is the leading cause of death in the modern society. A common...
