Effects of the endophyte Piriformospora indica on growth, physiology and water relations of tobacco (Nicotiana tobacum)
DownloadSpring 2012
In the current study, wildtype and transgenic tobacco constitutively over-expressing Arabidopsis aquaporins PIP 1;4 and PIP 2;5 were grown in association with the endophyte Piriformospora indica. Root hydraulic conductivity along with various physiological parameters and aquaporin expression were...

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...

Fall 2014
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,...

Introduction of Competition in Regulated Markets: Analysis of Colombia’s Natural Gas Industry
DownloadFall 2016
This dissertation deals with the introduction of competition in regulated industries such as natural gas. The thesis focuses on the recently developed Colombian natural gas market and uses a more mature market, the deregulated gas market existing in the province of Alberta, Canada, as a benchmark...

Respiration, Acid/Base, Ammonia and Ionoregulatory Strategies in the Pacific hagfish (Eptatretus stoutii)
DownloadFall 2016
Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...

Spring 2019
This dissertation delves into the anatomy and physiology of the phloem plant vascular tissue. Two primary topics are investigated in this thesis: (1) The cellular localization and response of aquaporin protein water channels in phloem sieve tubes and (2) the mathematical modeling of phloem sieve...

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...
