Ductile steel plate shear walls are an established lateral load resisting system. Past research indicates that cold-rolled infill panels less than 1 mm in thickness present one solution to an overstrength problem arising from selecting an infill panel thickness based on ease of welding and...

The effects of soil and plant nutrients on the oviposition preference, larval performance and spatial dynamics of Ceutorhynchus obstrictus and its parasitoids
DownloadFall 2010
The effects of nitrogen and sulfur fertilization on the oviposition, feeding preferences, and larval performance of Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae) on Brassica napus L. were examined in a series of laboratory experiments. The associations between C. obstrictus...

Coped beams are susceptible to fatigue cracking in the web at the cope radius when subjected to tension in the coped region. Use of an adhesively bonded composite patch over the crack can reduce the stress concentration and delay further crack growth. This report contains the results of a...

20Cr-32Ni-1Nb stainless steel alloys are commonly used in hydrogen reformer manifolds for transporting hot hydrogen by-products at 750-950 celcius. After long periods of exposure, embrittling secondary carbides and intermetallic phases can precipitate at the grain boundaries which can drastically...

Mercury is an air pollutant emitted from coal fired power plants. Once released into the environment, mercury undergoes conversion to organomercury compounds, which cause health concerns for both humans and animals. Many studies have been completed with the goal of reducing mercury emissions...

Coal Liquefaction Liquid Quality: Influence of Temperature and Heating Approach on Solvent Extraction of Coal
DownloadFall 2014
This project evaluated the impact of reaction temperature and of additional heating steps on the quality of the liquids obtained from solvent extraction of a lignite coal with tetralin. The points of focus were the coal liquid yield, physical properties, aromatic content and iron pyrite...

Diagenetic Controls on Hydrothermal Fluid Flow in the Osiris, Isis, and Isis East Carlin-Type Gold Showings, Nadaleen Trend, Yukon
DownloadFall 2015
Following ATAC Resources Ltd.’s 2010 discovery of the gold prospects in the Nadaleen Trend (Central Yukon), company geologists and consultants determined that Precambrian carbonate rocks within the trend contain large endowments of gold located in the hinges of anticlines and fault zones. ...

The Role of Sulfur Species in Establishing the Corrosion Reactions in Refinery Metallurgies
DownloadSpring 2016
This thesis is focused on the studying the role that model sulfur-containing molecules have in corrosion reactions on relevant metallurgies. This was done by using a design of experiments where a number of sulfur-based compounds were reacted with various metallurgies. The 8 model sulfur compounds...
