Using Polymerase Chain Reaction To Detect Nifh And Vnfdgk In A Novel Acidophilic Microbial Community, Samantha L. Flowers

Undergraduate Honors Theses

Acidophiles are widely known for their ability to exploit harsh environments, typically consisting of high temperatures, dissolved metal concentrations, and acidic conditions. Consequently, different acidophilic species are employed industrially in applications such as biomining and bioleaching. However, their full potential in bioremediation, and in industrial practices, has yet to be fully explored because many of these acidophiles are difficult to culture in laboratory conditions or have yet to be properly identified. This investigation focuses on a novel community sampled from the Richmond Mine site in Iron Mountain, California, consisting of a filamentous fungus and prokaryotes. This consortium can be cultured …

The "Playing" Field: Attitudes, Activities, And The Conflation Of Play And Games, Chad R. Carlson

Faculty Research and Creative Activity

Many philosophers have attempted to describe the nature of play and games. In doing so, they have come to a number of similar conclusions. Some authors speak of play and games interchangeably, while others regard them as two distinct phenomena. However, even some of those who attempted to distinguish games from play provided ambiguous or otherwise confusing descriptions. The end result has been a tendency to conflate the two entities. This conflation is so commonplace that we regularly speak of participating in all and any games as “playing games.” In this paper I address the issue of play-game conflation and …

Domain And Propositions Of Succession Theory, Steward Pickett, Scott Meiners, Mary Cadenasso

Faculty Research & Creative Activity

Succession is perhaps the oldest of ecological concepts, having arisen when ecology was emerging as a self-conscious discipline (Mcintosh 1985). Yet it continues to address many fundamental issues in ecology, to support important applications, and to synthesize the insights and perspectives of other theories. Thus, it fulfills two functions key in assessing the utility of a contemporary ecological theory. First, it exhibits the attributes of a mature, welldeveloped, and intensively tested theory (Glenn-Lewin et al. 1992; Pickett and Cadenasso 2005). Second, it provides a linkage among theories and applications that have usually been considered separately (Walker et al. 2007). For …

• Premise of the study : Recent analyses employing up to fi ve genes have provided numerous insights into angiosperm phylogeny, but many relationships have remained unresolved or poorly supported. In the hope of improving our understanding of angiosperm phylogeny, we expanded sampling of taxa and genes beyond previous analyses.

• Methods : We conducted two primary analyses based on 640 species representing 330 families. The fi rst included 25 260 aligned base pairs (bp) from 17 genes (representing all three plant genomes, i.e., nucleus, plastid, and mitochondrion). The second included 19 846 aligned bp from 13 genes (representing only …

Lea Proteins During Water Stress: Not Just For Plants Anymore, Steven C. Hand, Michael A. Menze, Mehmet Toner, Leaf Boswell, Daniel Moore

Faculty Research & Creative Activity

Late embryogenesis abundant (LEA) proteins are extremely hydrophilic proteins that were first identified in land plants. Intracellular accumulation is tightly correlated with acquisition of desiccation tolerance, and data support their capacity to stabilize other proteins and membranes during drying, especially in the presence of sugars like trehalose. Exciting reports now show LEA proteins are not restricted to plants; multiple forms are expressed in desiccation-tolerant animals from at least four phyla. We evaluate here the expression, subcellular localization, biochemical properties and potential functions of LEA proteins in animal species during water stress. LEA proteins are intrinsically unstructured in aqueous solution, but …

Quantitative Analysis Of Lignocellulosic Components Of Non-Treated And Steam Exploded Barley, Canola, Oat And Wheat Straw Using Fourier Transform Infrared Spectroscopy, P. K. Adapa, L. G. Schonenau, Thomas Canam, T. Dumonceaux

Faculty Research & Creative Activity

Rapid and cost effective quantification of lignocellulosic components (cellulose, hemicelluloses and lignin) of agricultural biomass (barley, canola, oat and wheat) is essential to determine the effect of various pre-treatments (such as steam explosion) on biomass used as feedstock for the biofuel industry. Fourier Transformed Infrared (FTIR) spectroscopy was considered as an option to achieve this objective. Regression equations having R2 values of 0.89, 0.99 and 0.98 were developed to predict the cellulose, hemicelluloses and lignin compounds of biomass, respectively. The average absolute difference in predicted and measured cellulose, hemicellulose and lignin in agricultural biomass was 7.5%, 2.5%, and 3.8%, respectively.
