Adaptive Divergence In The Thyroid Hormone Signaling Pathway In The Stickleback Radiation, Jun Kitano, Sean C. Lema, J. Adam Luckenbach, Seiichi Mori, Yui Kawagishi, Makoto Kusakabe, Penny Swanson, Catherine L. Peichel
Biological Sciences
During adaptive radiations, animals colonize diverse environments, which requires adaptation in multiple phenotypic traits. Because hormones mediate the dynamic regulation of suites of phenotypic traits, evolutionary changes in hormonal signaling pathways might contribute to adaptation to new environments. Here we report changes in the thyroid hormone signaling pathway in stream-resident ecotypes of threespine stickleback fish (Gasterosteus aculeatus), which have repeatedly evolved from ancestral marine ecotypes. Stream-resident fish exhibit a lower plasma concentration of thyroid hormone and a lower metabolic rate, which is likely adaptive for permanent residency in small streams. The thyroid-stimulating hormone-β2 (TSHβ …

Burning Manure As An Economical Energy Source, Ron Machado
Dairy Science
The dairy industry is under pressure from increasing environmental regulations, falling prices, as well as very aggressive foreign competition. Manure management and electrical costs are one area dairymen can look to cut costs. My objective for this project was to determine how cost effective biomass gasification of manure is at generating electricity. The proposed project was designed for a manure production equal to a 3,000 cow herd. I used standard capital budgeting techniques to determine the efficiency of the project, primarily focusing on the net present value, internal rate of return, and payback period.

Intelligent Planning And Assimilation Of Auv-Obtained Measurements Within A Roms-Based Ocean Modeling System, Benjamin J. Davini
Master's Theses
Efforts to learn more about the oceans that surround us have increased dramatically as the technological ability to do so grows. Autonomous Underwater Vehicles (AUVs) are one such technological advance. They allow for rapid deployment and can gather data quickly in places and ways that traditional measurement systems (bouys, profilers, etc.) cannot. A ROMS-based data assimilation method was developed that intelligently plans for and integrates AUV measurements with the goal of minimizing model standard deviation. An algorithm developed for this system is first described that optimizes paths for AUVs that seeks to improve the model by gathering data in high-interest …

Split Identification: Representations Of Rape In Gaspar Noé’S Irréversible And Catherine Breillat’S A Masoeur!/Fat Girl, Douglas Keesey
Split Identification: Representations Of Rape In Gaspar Noé’S Irréversible And Catherine Breillat’S A Masoeur!/Fat Girl, Douglas Keesey
English
This article critically examines rape scenes in two films of the new extreme cinema, Gaspar No's Irrversible (2002) and Catherine Breillat's A ma sur!/Fat Girl (2001). On the surface, No's disturbing long-take rape scene is clearly designed to foster empathy with the woman's experience and to induce a physical aversion to rape. However, a deeper examination of the scene's ambiguous techniques reveals that they actually work to split the viewer's identification between the rapist and the woman he attacks. One function of this split is to lead the viewer who is presumed to be male along an emotional path from …
