Embracing Commonplace: Creating Ground For A Life Of Rhetorically Engaged Civic Action, Jill K. Burk Jan 2014

Embracing Commonplace: Creating Ground For A Life Of Rhetorically Engaged Civic Action, Jill K. Burk

Electronic Theses and Dissertations

This project responds to the question: How do communication educators encourage students to enact the communicative practices necessary for a life of rhetorically engaged civic action? In responding to this question, the academic field of communication studies is recognized as a site for implementing the lessons of rhetoric, democracy, and civic engagement. This project contributes to the civic engagement scholarship from a communication studies perspective by foregrounding human communication as an essential component of the civic engagement process. As an interpretive inquiry, the philosophical thought and the pragmatic action of twentieth-century rhetorician and social activist Jane Addams (1860-1935) provides a …


The Role Of The B-Type Phospholipases In S. Cerevisiae: Function, Regulation, And Physiological Relevance In Lipid Homeostasis, Beth A Surlow Jan 2014

The Role Of The B-Type Phospholipases In S. Cerevisiae: Function, Regulation, And Physiological Relevance In Lipid Homeostasis, Beth A Surlow

Electronic Theses and Dissertations

Membrane phospholipid synthesis and turnover is a continual process during normal cell growth. The turnover of the glycerophospholipids by B-type phospholipases (PLBs) in Saccharomyces cerevisiae results in the formation glycerophosphodiesters through a deacylation reaction. Here, I address several aspects of the glycerophospholipid deacylation, transport, and reutilization pathway in S. cerevisiae. First, I show the RAS GTPase-activating proteins, Ira1 and Ira2, are required for utilization of the glycerophosphodiester - glycerophosphoinositol (GroPIns) - as a phosphate source. Second, I demonstrate loss of the cell surface associated PLBs, Plb1-3, and/or utilization of GroPIns causes actin cytoskeleton defects and an increased cell size. For …

Generally, solid tumors (>400 mm3) are inherently acidic, with more aggressive growth producing greater acidity. If the acidity could be targeted as a biomarker, it would provide a means to gauge the pace of tumor growth and degree of invasiveness, as well as providing a basis for predicting responses to pH-dependent chemotherapies. We have developed a 64Cu pH (low) insertion peptide (pHLIP) for targeting, imaging, and quantifying acidic tumors by PET, and our findings reveal utility in assessing prostate tumors. The new pHLIP version limits indiscriminate healthy tissue binding, and we demonstrate its targeting of extracellular …


Targeting Pancreatic Ductal Adenocarcinoma Acidic Microenvironment, Zobeida Cruz-Monserrate, Christina L. Roland, Defeng Deng, Thiruvengadam Arumugam, Anna Moshnikova, Oleg A. Andreev, Yana K. Reshetnyak, Craig D. Logsdon Jan 2014

Physics Faculty Publications

Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer death in the USA, accounting for ~40,000 deaths annually. The dismal prognosis for PDAC is largely due to its late diagnosis. Currently, the most sensitive diagnosis of PDAC requires invasive procedures, such as endoscopic ultrasonography, which has inherent risks and accuracy that is highly operator dependent. Here we took advantage of a general characteristic of solid tumors, the acidic microenvironment that is generated as a by-product of metabolism, to develop a novel approach of using pH (Low) Insertion Peptides (pHLIPs) for imaging of PDAC. We show that fluorescently labeled …

Landscape And Garden Plants Sample Submission To The Plant And Pest Diagnostic Clinic, Kevin Korus, Tamra Jackson-Ziems, James A. Kalisch, Lowell Sandell, Terri James

Nebraska Cooperative Extension: Faculty and Staff Publications

Diagnoses are made easier and turnaround time is improved when the quality of plant samples is maintained. This NebGuide discusses the proper guidelines for submitting landscape and garden plants, turf, and tree samples to UNL’s Plant and Pest Diagnostic Clinic.

There are several important things to consider when collecting, packaging, and sending plant or insect samples for diagnosis in a plant diagnostic laboratory. Collect an adequate amount of plant material. When feasible, the sample should include the entire plant — roots, stems, leaves, flowers, and fruits. Whole plants are needed to properly evaluate the sample. If the whole plant is …


Planting The Landscape, Kim Todd, Elizabeth Killinger, Terri James Jan 2014

Planting The Landscape, Kim Todd, Elizabeth Killinger, Terri James

Nebraska Cooperative Extension: Faculty and Staff Publications

A landscape is an investment of time and money that can be a beautiful, functional, and satisfying living space. Gardeners and landscape managers implementing integrated pest management strategies through good judgment in plant selection, site preparation, and planting practices will reduce insect, disease, and wildlife damage and will help ensure the growth and longevity of the investment.

Proper plant selection, site preparation, and planting practices are aspects of integrated pest management. Continued integration of correct cultural practices is important through proper mulching, watering, fertilizing, and other management practices to reduce pests.

Investigation Of Claims Of Late-Surviving Pterosaurs: The Cases Of The Winged Dragons Of Belon, Aldrovandi, And Cardinal Barberini, Phil Senter, Darius M. Klein Jan 2014

Investigation Of Claims Of Late-Surviving Pterosaurs: The Cases Of The Winged Dragons Of Belon, Aldrovandi, And Cardinal Barberini, Phil Senter, Darius M. Klein

College of Health, Science, and Technology

Here we investigate claims that pterosaurs survived into the sixteenth and seventeenth centuries. In 1557, 1640, and 1651 the European naturalists Pierre Belon, Ulisse Aldrovandi, and Giovanni Faber, respectively, published illustrations of winged, bipedal specimens that had been stuffed and mounted. Some recent young-Earth creationist authors claim that these specimens were recently-killed pterosaurs. The drawings and descriptions are detailed enough to test the pterosaur hypothesis as well as the alternative hypothesis that the specimens are taxidermic composites of parts of different animals. However, before now, no one has investigated these three cases or attempted to test these hypotheses. Here we …


Assessing And Managing Freshwater Ecosystems Vulnerable To Environmental Change, David G. Angeler, Craig R. Allen, Hannah E. Birgé, Stina Drakare, Brendan G. Mckie, Richard K. Johnson Jan 2014

Assessing And Managing Freshwater Ecosystems Vulnerable To Environmental Change, David G. Angeler, Craig R. Allen, Hannah E. Birgé, Stina Drakare, Brendan G. Mckie, Richard K. Johnson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Freshwater ecosystems are important for global biodiversity and provide essential ecosystem services. There is consensus in the scientific literature that freshwater ecosystems are vulnerable to the impacts of environmental change, which may trigger irreversible regime shifts upon which biodiversity and ecosystem services may be lost. There are profound uncertainties regarding the management and assessment of the vulnerability of freshwater ecosystems to environmental change. Quantitative approaches are needed to reduce this uncertainty. We describe available statistical and modeling approaches along with case studies that demonstrate how resilience theory can be applied to aid decision-making in natural resources management. We highlight especially …

Farm Bill 2014: An Experimental Investigation Of Conservation Compliance, Hans J. Czap, Natalia V. Czap, Gary D. Lynne Jan 2014

Farm Bill 2014: An Experimental Investigation Of Conservation Compliance, Hans J. Czap, Natalia V. Czap, Gary D. Lynne

Department of Agricultural Economics: Faculty Publications

Leading up to the 2014 Farm Bill, the House of Representatives and the Senate proposed alternative changes to the incentive structure for farmer conservation efforts. While both include crop insurance subsidies, the version proposed by the Senate made such subsidies conditional on conservation efforts. This study uses experimental methods to analyze the efficacy of these two alternative designs in comparison to the previous, 2008 Farm Bill, design and investigates in how far additional nudging for empathy can improve on the efficiency. The results support the contention that solely offering financial incentives, as is the case in the 2014 Farm Bill, …


Controlled De-Cross-Linking And Disentanglement Of Feather Keratin For Fiber Preparation Via A Novel Process, Helan Xu, Yiqi Yang Jan 2014

Controlled De-Cross-Linking And Disentanglement Of Feather Keratin For Fiber Preparation Via A Novel Process, Helan Xu, Yiqi Yang

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Pure protein fibers were fabricated from chicken feathers via a potentially green process. In the last several decades, efforts have been made to produce keratin-based industrial products, especially fibers. However, the methods of producing keratin fibers directly from chicken feathers could not be repeated. In this research, protein fibers from chicken feathers were developed using chemicals that could be either derived from renewable resources or facilely recycled. Backbones of keratin were preserved after cleavage of disulfide bonds using cysteine. Sodium dodecyl sulfate (SDS) was applied to dissolve keratin for spinning. Increasing SDS concentration intensified the ordered conformation of keratin, first …


Introduction [To Automation: The Future Of Weed Control In Cropping Systems]: Scope Of The Problem—Rising Costs And Demand For Environmental Safety For Weed Control, Stephen L. Young, Francis J. Pierce, Pete Nowak Jan 2014

Introduction [To Automation: The Future Of Weed Control In Cropping Systems]: Scope Of The Problem—Rising Costs And Demand For Environmental Safety For Weed Control, Stephen L. Young, Francis J. Pierce, Pete Nowak

West Central Research and Extension Center, North Platte

Many organic and conventional producers rank weed control as their number one production cost. For organic producers particularly, weed control has become increasingly important as organic production has increased its market share. In conventional systems, herbicide resistance, off-target movement, and increased regulations have left many growers with few alternatives. Added to this is an increasing demand from the public for a safer and more sustainable supply of food. This chapter addresses the problems of mechanized agricultural systems to set the stage for the introduction and adoption of more advanced technology to meet the needs of growers and satisfy the desires …


Effect Of Development System On Growth And Reproductive Performance Of Beef Heifers, H. A. Lardner, D. Damiran, S. Hendrick, K. Larson, R. Funston Jan 2014

Effect Of Development System On Growth And Reproductive Performance Of Beef Heifers, H. A. Lardner, D. Damiran, S. Hendrick, K. Larson, R. Funston

West Central Research and Extension Center, North Platte

Reproductive performance was evaluated in beef heifers born over a 2-yr period to determine the effects of target breeding weight (TBW) and development system (SYS) on growth and subsequent reproductive efficiency. Spring-born Angus heifers (253 ± 0.7 kg) were randomly allocated over 2 consecutive yr (yr 1, n = 80; yr 2, n = 96) to be developed to either 55% (350 kg) of mature BW (moderate gain, MG) or 62% (395 kg) of mature BW (high gain, HG). Each MG and HG group was further assigned to 1 of 2 replicated systems: (1) bale graze bromegrass-alfalfa round bales in …

Bioeconomic Factors Of Beef Heifer Maturity To Consider When Establishing Criteria To Optimally Select And/Or Retain Herd Replacements, M. C. Stockton, R. K. Wilson, D. M. Feuz, L. A. Stalker, R. N. Funston

West Central Research and Extension Center, North Platte

Understanding the biology of heifer maturity and its relationship to calving difficulty and subsequent breeding success is a vital step in building a bioeconomic model to identify optimal production and profitability. A limited dependent variable probit model is used to quantify the responses among heifer maturities, measured by a maturity index (MI), on dystocia and second pregnancy. The MI account for heifer age, birth BW, prebreeding BW, nutrition level, and dam size and age and is found to be inversely related to dystocia occurrence. On average there is a 2.2% increase in the probability of dystocia with every 1 point …

Edible Grain Legumes, George J. Vandemark, Mark A. Brick, Juan M. Osorno, James D. Kelly, Carlos A. Urrea

Panhandle Research and Extension Center

Edible grain legumes, including dry bean (Phaseolus vulgaris L.), dry pea (Pisum sativum L.), chickpea (Cicer arientinum L.), and lentil (Lens culinaris Medikus), have served as important sources of protein in the human diet for thousands of years. In the United States, these crops are consumed nationally and produced for export markets. The objectives of this study were to examine yield gains in edible grain legume crops over the past 25 yr. Genetic gain in dry bean during the past 30 yr based on common trials was 13.9 kg ha−1 yr−1 (0.77% yr …

Development Of A Fatal Noncompressible Truncal Hemorrhage Model With Combined Hepatic And Portal Venous Injury In Normothermic Normovolemic Swine, Ujwal R. Yanala, Jason M. Johanning, Iraklis I. Pipinos, Gustavo F. Larsen, William H. Velander, Mark A. Carlson Jan 2014

Development Of A Fatal Noncompressible Truncal Hemorrhage Model With Combined Hepatic And Portal Venous Injury In Normothermic Normovolemic Swine, Ujwal R. Yanala, Jason M. Johanning, Iraklis I. Pipinos, Gustavo F. Larsen, William H. Velander, Mark A. Carlson

Department of Chemical and Biomolecular Engineering: Faculty Publications

Noncompressible truncal hemorrhage and brain injury currently account for most early mortality of warfighters on the battlefield. There is no effective treatment for noncompressible truncal hemorrhage, other than rapid evacuation to a surgical facility. The availability of an effective field treatment for noncompressible truncal hemorrhage could increase the number of warfighters salvaged from this frequently-lethal scenario. Our intent was to develop a porcine model of noncompressible truncal hemorrhage with a ,50% one-hour mortality so that we could develop new treatments for this difficult problem. Normovolemic normothermic domestic swine (barrows, 3 months old, 34–36 kg) underwent one of three injury types …
