Changing with the seasons : does vitamin D affect mood?

Creator:: Downing, Dave G. and Kerr, David C. R.
Abstract:: Seasonality is defined as a change in mood and behavior with the seasons. Research shows there is a possible connection between vitamin D levels and mood (Murphy & Wagner, 2008; Lansdowne & Provost, 1998). Given that vitamin D is produced when skin is exposed to sunlight and varies with sun...

High-resolution infrared studies of perdeutero-spiropentane, C₅D₈

Creator:: Erickson, Blake Alexander, Ju, X., Nibler, Joesph W., Beaudry, C. M., and Blake, T. A.
Abstract:: Perdeutero-spiropentane (C₅D₈) has been synthesized and infrared and Raman spectra are reported for the first time. Wavenumber assignments are made for most of the fundamental vibrational modes. Gas phase infrared spectra were recorded at a resolution (0.002 cm⁻¹) sufficient to resolve individual rovibrational lines and show evidence of strong Coriolis...

Difference in prostate cancer rates between the United States and Spain : effect of vitamin D

Creator:: Marvel, Kathryn
Abstract:: Prostate cancer is the most commonly diagnosed cancer in men, but rates around the world vary greatly. Americans have the highest incidence rates in the world, 4 to 5 times those of Spain. The hypothesis of this thesis was that vitamin D metabolism is a factor in prostate cancer development...

The Design and Construction of a 5 K.W., D. C. generator

Creator:: Gilkey, Jesse Smart and Chapman, Alexander Kesterson
Abstract:: Since this treatise is to deal only with the construction of one special machine it is unnecessary to go into an extended discussion of dynamo electric machinery in general. Some of the parts common to all electric machinery of this character will be mentioned and then a short account of...

Partial purification of endo-1,4-β-D-glucanase I of Trichoderma reesei and use in small-scale enzymatic hydrolysis of cellulose

Creator:: Pautsch, Lindsay
Abstract:: In order to reduce the cost of lignocellulosic ethanol production, a model was previously developed to predict the amount of fermentable sugar released based on parameters concerning both biomass and enzymes. To validate this model, enzymatic hydrolysis must be carried out using individual purified cellulase enzymes. Endo-1,4-β-D-glucanase I (EG I),...

Effects of Contemporary Forest Practices on Stream Nutrients, Temperature, and Periphyton in Small Headwater Streams

Creator:: Pimont, Cedric
Abstract:: Forest harvest practices can impact nutrient concentrations and stream temperatures, altering aquatic ecosystems. To better inform future sustainable forest resource management practices, quantifying the impact of current practices on water quality, particularly in headwater streams is important. In this study, I quantified monthly nitrate-nitrite (N) and orthophosphate (P) concentrations, 7-day...

Using 4-D imaging of the zebrafish model to observe pharmacodynamics of a therapeutic drug on glioblastoma

Creator:: Means, Sophie, Gamble, John, Wehmas, Leah, and Greenwood, Julie
Abstract:: Glioblastoma Multiform • Type of aggressive brain cancer • Five year survival rate of 4.70% • Not often detected until it’s in the later stages when the symptoms appear • Surgery is not an effective option due to invasion and proliferation of glioblastoma cells outside of the tumor mass before...

Analyzing the molecular basis of increased enduracidin production in Streptomyces fungicidicus

Creator:: Herinckx, Molly A.
Abstract:: Enduracidin is an antibiotic produced by Streptomyces fungicidicus that is effective against Gram-positive bacteria. Previous work identified seventy-eight mutations in an S. fungicidicus strain that produces a significantly higher level of enduracidin than the wild type strain, ATCC 21013. Eleven mutations were analyzed individually to identify those that may contribute...

Variation in Irc7p activity amongst brewing strains of Saccharomyces cerevisiae

Creator:: Vega, Esteban A.
Abstract:: Polyfunctional thiols are sulfur containing compounds that are important to the flavor and aroma profile of some foods and beverages. S. Cerevisiae has been shown in wine yeast that it is capable of producing these thiols to create a fruity aroma and flavor profile. IRC7, a gene that codes the...
