Applications of nonautonomous infinite-dimensional systems control theory for parabolic PDEs
DownloadFall 2013
Parabolic partial differential equations (PDEs) are used as models of transport-reaction phenomena in a variety of different industrial chemical and materials engineering processes, and can yield precise descriptions of process variables with complex temporal and spatially dependent system...

This dissertation describes a series of experiments that examined: 1) hydraulic responses of Populus trichocarpa x deltoides, Populus trichocarpa and Picea glauca plants to change in their surrounding environment; 2) Changes of aquaporin expression in response to such changes. In the first study,...

Macdonald, S. Ellen, Islam, M. Anisul
We investigated the effects of flooding for three weeks on physiological responses and uptake of NH4+ and NO3- by black spruce (Picea mariana (Mill.) BSP.) and tamarack (Larix laricina (Du Roi) K. Koch) seedlings fertilized with labeled (15NH4)2SO4 or K15NO3 in a growth chamber experiment....

DHR51 as a coordinator of heme biosynthesis and steroid hormone production to time metamorphosis in Drosophila melanogaster
DownloadFall 2019
Development from a juvenile to an adult animal is driven by pulses of steroid hormones released at precise developmental times. Inputs from the environment, timing cues, and nutritional factors are all coordinated to produce a steroid hormone pulse. Insects and in particular, the fruit fly...

Disinformation, Stochastic Harm, and Costly Effort: A Principal-Agent Analysis of Regulating Social Media Platforms
DownloadFall 2022
The spread of disinformation on social media platforms is harmful to society. This harm may manifest as a gradual degradation of public discourse; but it can also take the form of sudden dramatic events such as the 2021 insurrection on Capitol Hill. The social media platforms themselves are in...

Perkins, S., Zuidhof, Martin J., Feddes, John J. R., Robinson, Frank E.
Four environmental chambers housing either 75 (5.5 birds/m\") or 37 turkeys (2.8 birds/m ) were used to study the impact of stocking density on air quality, bird health, and performance under similar per bird ventilation rates (3 L/s per bird). Stocking density had little effect on air quality or...
