Effects Of Compost On Prairie Seedling Establishment And Seed Production, Thomas R. Rosburg, Emiy Sibigtroth, Adam Palmer Aug 2014

Effects Of Compost On Prairie Seedling Establishment And Seed Production, Thomas R. Rosburg, Emiy Sibigtroth, Adam Palmer

The Prairie Naturalist

Compost is a commonly used soil amendment in horticultural and agricultural practices that is generally known to improve soil conditions and plant growth. We conducted a field experiment to investigate the application of compost to prairie production plots as a method to improve seedling establishment and growth and the seed production of established plants. We evaluated the effect of compost depth and tillage on the survivorship, growth, reproduction and ecophysiology of several prairie plant species commonly used in restoration. Results were mixed; for some species, transplants in compost–amended plots incurred lower survivorship and reduced growth compared to control plots. When …

Reproductive Failure In Largeleaf Wild Indigo In A Restored Prairie In Southeastern Minnesota, Neal D. Mundahl Aug 2014

Reproductive Failure In Largeleaf Wild Indigo In A Restored Prairie In Southeastern Minnesota, Neal D. Mundahl

The Prairie Naturalist

Native prairie restorations in many regions of the United States have been hindered by various herbivores consuming plant reproductive parts or products. I conducted field studies of a population of largeleaf wild indigo (Baptisia lactea) on a restored prairie in southeastern Minnesota during the growing seasons of 2010–2012 to determine the cause(s) of repeated reproductive failure. I assessed plants for browsing damage caused by white-tailed deer (Odocoileus virginianus) during the period of flowering and with a deer exclosure experiment involving caged and non-caged plants. I compared reproductive output (numbers of seed pods, viable seeds) of caged …

Association Of Soil Conditions And Grass Species With Variable Cover Of Leafy Spurge, Terence P. Mcgonigle, Jeremy L. Timmer Aug 2014

Association Of Soil Conditions And Grass Species With Variable Cover Of Leafy Spurge, Terence P. Mcgonigle, Jeremy L. Timmer

The Prairie Naturalist

Variation in soil conditions and grass cover was assessed across a range of leafy spurge (Euphorbia esula L.) cover values on a sandy rangeland in Manitoba, Canada. Soil conditions varied by site but not in relation to cover of leafy spurge. We observed a significant negative relationship between total grass cover and increasing cover of leafy spurge. Only porcupine grass (Hesperostipa spartea [Trin.] Barkworth) had a negative relationship with leafy spurge, falling from high cover at low weed occurrence to only trace levels at the highest leafy spurge abundance. Neither prairie Junegrass (Koeleria macrantha [Ledeb.] Schult.), rough …

Evaluation Of Volatile And Semi-Volatile Organic Compounds Potentially Associated With The Gas Shale Fracturing Process In The Fayetteville And Marcellus Shale, Karl Albert Oetjen Aug 2014

Evaluation Of Volatile And Semi-Volatile Organic Compounds Potentially Associated With The Gas Shale Fracturing Process In The Fayetteville And Marcellus Shale, Karl Albert Oetjen

Theses - ALL

With the recent growth of the natural gas industry coupled with technological advancements, gas shale fracturing has become an effective and highly profitable method for natural gas production. Unlike conventional natural gas extraction which may require vertical fracturing, gas shale fracturing relies on a method known as horizontal fracturing to remove gas trapped within the impermeable facies. Compared to vertical fracturing, horizontal fracturing requires larger amounts of fluids to be injected downhole under high pressure. These fracturing fluids can contain high concentrations of petroleum hydrocarbons with known adverse health effects. Due to the large volumes used, the potential for groundwater …

Acoustic Communication In The Temperate Treefrogs Pseudacris Crucifer And Acris Crepitans, John Keating

All-Inclusive List of Electronic Theses and Dissertations

Spring peepers and cricket frogs produce advertisement calls to attract females. As ectotherms their body temperatures are greatly affected by ambient air temperature. Some characteristics of their advertisement calls are correlated with temperature. I analyzed advertisement calls of both species recorded in western-central Indiana. I compared call characteristic correlations with temperature found in our populations to those in populations in other geographic areas and found similar trends throughout the range of both species. Secondly, I examined aggressive calls in the spring peepers. Aggressive calls are used in male-male interactions, and in the spring peeper are a distinct call type different …

A Streamline Upwind/ Petrov-Galerkin Fem Based Time-Accurate Solution Of 3d Time-Domain Maxwell's Equations For Dispersive Materials, Srijith Rajamohan Aug 2014

A Streamline Upwind/ Petrov-Galerkin Fem Based Time-Accurate Solution Of 3d Time-Domain Maxwell's Equations For Dispersive Materials, Srijith Rajamohan

Masters Theses and Doctoral Dissertations

Although the simulation of most broadband frequency responses are made under the assumption of constant electromagnetic material parameters, this is not a valid assumption for many materials found in nature. In this dissertation the time-accurate solution of the 3D time-domain Maxwell’s equations for dispersive materials in a Streamline Upwind/Petrov-Galerkin framework is investigated. For this purpose the permittivity associated with a material is expressed as a matrix, enabling the solution of anisotropic material models with multiple poles. Here diagonally isotropic models with up to 2 poles are investigated. Near-field to far-field transformations are implemented to enable the solution of open boundary …

The Power Of Words In Tension: Enterprise/Strategy As A Dilemma In Neoliberalism’S Persistence., Brendan O'Rourke Aug 2014

The Power Of Words In Tension: Enterprise/Strategy As A Dilemma In Neoliberalism’S Persistence., Brendan O'Rourke

Conference papers

We address how enterprise is related to, another important discourse, strategy. From a discourse analysis of the talk of small firm owner-managers, emerges a view of strategy and enterprise as a single, integrated entity, bound together by some commonalities but more importantly by paired opposites reminiscent of ideological dilemmas (Billig, Condor, Edwards, Gane, Middleton & Radley, 1988). This dilemmatic nature of enterprise/strategy discourse adds to explanations for the persistence of the neoliberal form of enterprise, with the entrepreneur as the heroic saviour of all, based on the entrepreneur as an empty signifier (Jones & Spicer, 2009; Kenny & …

Electrokinetic Instabilities In Ferrofluid Microflows, Dhileep Thanjavur Kumar Aug 2014

Electrokinetic Instabilities In Ferrofluid Microflows, Dhileep Thanjavur Kumar

All Theses

Lab-on-a-chip devices have been increasingly used in the past two decades for chemical and biomedical analysis. These devices employ the concepts of microfluidics and offer the promise of incorporating multiple laboratory processes onto a single portable chip. Electric field has been often employed in microfluidic devices for the ease of fluid and sample control as well as the convenience of chip integration and interfacing. Flow instabilities can take place when two fluids of unequal electrical properties are pumped through a microchannel under the application of an adequately strong electric field. The study of these electrokinetic instabilities in microfluidic devices is …

Protein Nano-Object Integrator: Generating Atomic-Style Objects For Use In Molecular Biophysics, Nicholas Smith Aug 2014

Protein Nano-Object Integrator: Generating Atomic-Style Objects For Use In Molecular Biophysics, Nicholas Smith

All Theses

As researchers obtain access to greater and greater amounts of computational power, focus has shifted towards modeling macroscopic objects while still maintaining atomic-level details. The Protein Nano-Object Integrator (ProNOI) presented here has been designed to provide a streamlined solution for creating and designing macro-scale objects with atomic-level details to be used in molecular simulations and tools. To accomplish this, two different interfaces were developed: a Protein Data Bank (PDB), PDB-focused interface for generating regularly-shaped three-dimensional atomic objects and a 2D image-based interface for tracing images with irregularly shaped objects and then extracting three-dimensional models from these images. Each interface is …

Altered Community Flammability In Florida's Apalachicola Ravines And Implications For The Persistence Of The Endangered Conifer Torreya Taxifolia., John M. Mola, J. Morgan Varner, Erik S. Jules, Tova Spector

CALS Publications

Plant species and communities often reflect historic fire regimes via ecological and evolutionary responses to recurrent fires. Plant communities of the southeastern USA experience a wide array of fire regimes, perhaps nowhere more marked than the juxtaposition of fire-prone uplands and adjacent mesic ravines along Florida's Apalachicola River. The ravines contain many endemic and disjunct species, most notably the endangered endemic conifer Torreya taxifolia. A rapid decline in T. taxifolia over the past 60 years has been associated with widespread replacement by other tree species. To understand the changes accompanying the shift in ravine composition, we compared leaf litter flammability …

Gene Discovery And Differential Expression Analysis Of Humoral Immune Response Elements In Female Culicoides Sonorensis (Diptera: Ceratopogonidae), Naya Nayduch, Matthew B. Lee, Christopher Saski Aug 2014

Gene Discovery And Differential Expression Analysis Of Humoral Immune Response Elements In Female Culicoides Sonorensis (Diptera: Ceratopogonidae), Naya Nayduch, Matthew B. Lee, Christopher Saski

Publications

Female Culicoides sonorensis midges (Diptera: Ceratopogonidae) are vectors of pathogens that impact livestock and wildlife in the United States. Little is known about their biology on a molecular-genetic level, including components of their immune system. Because the insect immune response is involved with important processes such as gut microbial homeostasis and vector competence, our aims were to identify components of the midge innate immune system and examine their expression profiles in response to diet across time.

Σ(N) -Dependent Control Of Acid Resistance And The Locus Of Enterocyte Effacement In Enterohemorrhagic Escherichia Coli Is Activated By Acetyl Phosphate In A Manner Requiring Flagellar Regulator Flhdc And The Σ(S) Antagonist Fliz, Avishek Mitra, Pamela A. Fay, Khoury W. Vendura, Zimrisha Alla, Ronan K. Carroll, Lindsey N. Shaw, James T. Riordan

Molecular Biosciences Faculty Publications

In enterohemorrhagic Escherichia coli (EHEC), sigma factor N (σN) regulates glutamate-dependent acid resistance (GDAR) and the locus of enterocyte effacement (LEE); discrete genetic systems that are required for transmission and virulence of this intestinal pathogen. Regulation of these systems requires nitrogen regulatory protein C, NtrC, and is a consequence of NtrC-σN-dependent reduction in the activity of sigma factor S (σS). This study elucidates pathway components and stimuli for σN-directed regulation of GDAR and the LEE in EHEC. Deletion of fliZ, the product of which reduces σS activity, …

Debunking The Myth Of Money In A Multigenerational Workforce, S.T. Lee, S. Jayasingam, K.N. Mohd Zain Aug 2014

Debunking The Myth Of Money In A Multigenerational Workforce, S.T. Lee, S. Jayasingam, K.N. Mohd Zain

Research Publications (2011 to 2015)

Money is a common denominator used to purchase goods and services worldwide. People work for money to survive. Organizations spend millions to pay the salaries of their employees with the hope for better performance in return. Undeniably, money influences people's lives to a certain extent. However, can it motivate every individual or is there a misguided perception that everyone is money driven? This question is becoming pertinent especially with Baby Boomers, Generation X, and Generation Y entering the workforce and transforming the workforce demographics. It is no longer a homogeneous group.

The Use Of Oxidants For Ndma Precursor Deactivation In Wastewater Treatment, Jaclyn Lauer Aug 2014

The Use Of Oxidants For Ndma Precursor Deactivation In Wastewater Treatment, Jaclyn Lauer

All Theses

Water treatment plants in the United States (US) have been switching from chlorination to chloramination in the search for a disinfection process to reduce formation of regulated disinfection by-products (DBPs). Unfortunately, the trade-off is the formation of N-nitrosamines. N-nitrosodimethylamine (NDMA) is the most commonly detected N-nitrosamine in US distribution systems. In the Integrated Risk Information Service (IRIS) database of the United States Environmental Protection Agency (USEPA), NDMA has been identified to have an estimated 10-6 lifetime cancer risk level at a concentration of 0.7 ng/L in drinking water. N-nitrosamines are currently not regulated by the USEPA; however, are listed on …
