C And N Cycling Dynamics And Microbial Community Composition In High Tunnel Production Systems, Kavita Lakshmi Mizin

Theses and Dissertations--Plant and Soil Sciences

Across the United States, high tunnels are used as a means of season extension and control over climatic variability in fruit and vegetable production. However, high tunnel systems are an intensive form of agricultural production which may compromise soil and crop quality over time. This study examined the effects of the varying environmental conditions, created in two types of tunnel system, movable and stationary, on the flow of nitrogen from amendment to plant and impact on crop and soil quality parameters. The way nutrients cycled through these systems was different and the nutrient treatments had no consistent effects on soil …

Evaluating The Effect Maturity On The Intake And Digestibility Of Switchgrass Hay Consumed By Beef Steers, David H. Davis

Theses and Dissertations--Plant and Soil Sciences

There has been increased interest in utilizing switchgrass (Panicum virgatum) as biomass. There are several challenges to developing this industry, and these have led to the potential use of switchgrass as hay for feeding beef cattle in Kentucky. The effect of increasing maturity on crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and nutritive values of switchgrass hay has been well documented, but few in vivo intake and digestibility trials have been conducted to assess this effect on animal performance when feeding beef cattle. Two in vivo intake and digestibility trials were conducted in 2011 …

The Influence Of Tall Fescue Cultivar And Endophyte Status On Root Exudate Chemistry And Rhizosphere Processes, Jingqi Guo

Theses and Dissertations--Plant and Soil Sciences

Tall fescue (Lolium arundinaceum (Schreb.) Darbysh.) is a cool-season perennial grass used in pastures throughout the Southeastern United States. The grass can harbor a fungal endophyte (Epichloë coenophiala) thought to provide the plant with enhanced resistance to biotic and abiotic stress. However, the alkaloids produced by the common variety of the endophyte cause severe animal health issues resulting in a considerable amount of research focused on eliminating the toxic class of alkaloids while retaining the positive abiotic and biotic stress tolerance attributes of the other alkaloids. In doing so, very little attention has been paid to the …

Bacteria In Bioethanol Fermentations, Qing Li

Theses and Dissertations--Plant and Soil Sciences

To gain a better understanding of contaminating bacteria in bioethanol industry, we profiled the bacterial community structure in corn-based bioethanol fermentations and evaluated its correlation to environmental variables. Twenty-three batches of corn-mash sample were collected from six bioethanol facilities. The V4 region of the collective bacterial 16S rRNA genes was analyzed by Illumina Miseq sequencing to investigate the bacterial community structure. Non-metric multidimensional scaling (NMDS) ordination plots were constructed to visualize bacterial community structure groupings among different samples, as well as the effects of multiple environmental variables on community structure variation. Our results suggest that bacterial community structure is facility-specific, …

Evaluation Of Correlation Between Within-Barn Curing Environment And Tsna Accumulation In Dark Air-Cured Tobacco, Mitchell Dale Richmond

Theses and Dissertations--Plant and Soil Sciences

Significant variability in cured leaf tobacco-specific nitrosamine (TSNA) content is commonly observed when sampling within dark air-curing barns. This variability may be due to inconsistency in the curing environment within different areas of the barn. A study was initiated in 2012 through support from a CORESTA Study Grant to evaluate if leaf TSNA content is related to microenvironmental conditions in the barn. Seed screened for low conversion of nicotine to nornicotine (sc) and high converter (HC) selections of TR Madole dark tobacco were cured in barns near Princeton and Lexington, Kentucky in 2012 and 2013. Temperature and relative humidity were …

Mandatory Ultrasound Statutes And The First Amendment, Shifting The Constitutional Perspective, Cheri D. Smith

Cardozo Journal of Equal Rights & Social Justice

The jurisprudence of abortion law is replete with instances in which the concerns of the woman seeking the procedure have taken a back seat. The newest battleground in abortion regulation involves mandatory ultrasound statutes touted as informed consent regulations. The analysis of courts confronting these statutes has turned on whether the mandatory disclosures violate the physician's First Amendment right to be free from compelled speech. The particular breed of statute at issue in this paper requires a physician not only to perform an ultrasound, but also to make the images visible to the woman, to make audible the heartbeat, and …

Effect Of Laser-Cut Slow-Flow Nipples On Preterm Feeding Performance, Katlyn Elizabeth Mcgrattan

MUSC Theses and Dissertations

Background: Dysphagia of prematurity is a highly prevalent condition that carries negative developmental, social, and financial implications. Although the modification of bottle nipple properties is a widely used treatment for dysphagia of prematurity, there have been a paucity of investigations examining the effect of this intervention on refined measures of feeding performance. Methods: Healthy preterm infants were evaluated for measures of milk ingestion and respiratory performance during oral intake on a laser-cut slow-flow and standard-flow nipple. Time to achieve hospital discharge milestones was recorded. Results: Few differences were observed in feeding performance between slow-flow and standard-flow nipples. Characteristics of respiration …

Effect Of Abiotic Factors On Initiation Of Red Flour Beetle (Coleoptera: Tenebrionidae) Flight, Joel Perez-Mendoza, James F. Campbell, James E. Throne

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Traps baited with pheromones are used to monitor the red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), populations in flour mills to aid in making pest management decisions, but the factors that influence T. castaneum movement are not fully understood. We investigated the impact of photoperiod, light intensity, temperature, and relative humidity on flight initiation. The percentage of adults initiating flight reached a maximum at 30-35°C, and then fell to zero at 22.5 and 45°C. Only 2% of beetles flew in complete darkness, and the number of beetles initiating flight increased to 41% under 18 h of light and then …

Lymphoproliferative And Gamma Interferon Responses To Stress- Regulated Mycobacterium Avium Subsp. Gurungparatuberculosis Recombinant Proteins, Ratna B. Gurung, Douglas J. Begg, Auriol C. Purdie, Kumudika De Silva, John Bannantine, Richard J. Whittington

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Johne’s disease in ruminants is a chronic infection of the intestines caused by Mycobacterium avium subsp. paratuberculosis. An important strategy to control disease is early detection, and a potentially efficient method for early detection is measurement of cell-mediated immune responses developed by the host in response to exposure or infection. One method is to measure lym- phoproliferation and cytokine release from the host cells when exposed to the organism or parts of the organism. In this study, 10 recombinant M. avium subsp. paratuberculosis proteins known to be upregulated under in vitro stress conditions were evalu- ated by examining their ability …

Sorghum Flour Characterization And Evaluation In Gluten-Free Flour Tortilla, M. Winger, H. Khouryieh, F. Aramouni, T. Herald

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Four sorghum hybrids (Fontanelle-625 [F-625]), Fontanelle-1000 [F-1,000], ATx631xRTx2907 [NE#20] and 5,040C) were characterized and evaluated for kernel characteristics, proximate analysis, flour characterization (particle size distributions, starch damage, amylose content and starch pasting properties) and end product in gluten-free tortilla. A commercial sorghum flour (TVM) was used as a control. Significant differences were found (P < 0.05) among hybrids for kernel and flour composition except total starch (P > 0.05). NE#20 had the largest particle diameter for both flour and starch. F-1000 had significantly higher starch damage compared with the other hybrids. Flours with smaller particle size and higher starch damage contributed to softer and more extensible tortilla. Amylose content ranged from 20.2 (NE#20) to …

Grazing Management, Season, And Drought Contributions To Near-Surface Soil Property Dynamics In Semiarid Rangeland, M. A. Liebig, S. L. Kronberg, J. R. Hendrickson, J. R. Gross

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Grazing management effects on soil property dynamics are poorly understood. A study was conducted to assess effects of grazing management and season on soil property dynamics and greenhouse gas flux within semiarid rangeland. Grazing management treatments evaluated in the study included two permanent pastures differing in stocking rate (moderately and heavily grazed pastures) and a fertilized, heavily grazed crested wheatgrass (Agropyron desertorum [Fisch. ex. Link] Schult.) pasture near Mandan, North Dakota. Over a period of 3 yr, soil properties were measured in the spring, summer, and fall at 0–5 cm and 5–10 cm. Concurrent to soil-based measurements, fluxes of carbon …

Modeling Weather And Stocking Rate Effects On Forage And Steer Production In Northern Mixed-Grass Prairie, Q. X. Fang, A. A. Andales, J. D. Derner, L. R. Ahuja, L. Ma, P. N. S. Bartling, J. L. Reeves, Z. Qi

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Stocking rate (SR) is the primary management factor that influences livestock gains, plant community changes and forage production, as well as economic returns for livestock producers. More effective stocking decision making by ranchers in the semi-arid northern mixed-grass prairie requires clearly understanding forage production and yearling steer weight gain (SWG) responses to SR and high weather variability. The objectives of this study were to: (1) test the Great Plains Framework for Agricultural Resource Management-Range (GPFARM-Range) model for predicting forage production and SWG under three experimental SR treatments and long-term weather conditions on semiarid northern mixed-grass prairie in southeast Wyoming, USA; …

The Biophysical Link Between Climate, Water, And Vegetation In Bioenergy Agro-Ecosystems, Justin E. Bagley, Sarah C. Davis, Matei Georgesu, Mir Zaman Hussain, Jesse Miller, Stephen W. Nesbitt, Andy Vanloocke, Carl J. Bernacchi

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Land use change for bioenergy feedstocks is likely to intensify as energy demand rises simultaneously with increased pressure to minimize greenhouse gas emissions. Initial assessments of the impact of adopting bioenergy crops as a significant energy source have largely focused on the potential for bioenergy agroecosystems to provide global-scale climate regulating ecosystem services via biogeochemical processes. Such as those processes associated with carbon uptake, conversion, and storage that have the potential to reduce global greenhouse gas emissions (GHG). However, the expansion of bioenergy crops can also lead to direct biophysical impacts on climate through water regulating services. Perturbations of processes …

Soil Greenhouse Gas Emissions In Response To Corn Stover Removal And Tillage Management Across The Us Corn Belt, Virginia L. Jin, John M. Baker, Jane M.F. Johnson, Douglas Karlen, R. Michael Lehman, Shannon L. Osborne, Thomas J. Sauer, Diane E. Stott, Gary E. Varvel, Rodney T. Venterea, Marty R. Schmer, Brian J. Wienhold

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

In-field measurements of direct soil greenhouse gas (GHG) emissions provide critical data for quantifying the net energy efficiency and economic feasibility of crop residue based bioenergy production systems. A major challenge to such assessments has been the paucity of field studies addressing the effects of crop residue removal and associated best practices for soil management (i.e., conservation tillage) on soil emissions of carbon dioxide (CO₂), nitrous oxide (N₂O), and methane (CH₄). This regional survey summarizes soil GHG emissions from nine maize production systems evaluating different levels of corn stover removal under conventional or conservation …

Design And Development Of Scalable Solar Powered Water Purification Systems For Developing Nations, Shavin Pinto

Doctoral Dissertations and Master's Theses

This thesis presents the design and development of solar powered water purification systems. The systems were designed to meet specific customer requirements that were established from the experiences gained after the installation of five water purification systems in various Haitian communities. The systems are scalable and are able to supply 10,000-20,000 gallons of clean drinking water per day. The design consists of a three-stage filtration system with a disc-type sediment filter, a 0.1 micron ultrafiltration membrane, and an ultraviolet light for disinfection. The backwash cycle extends the life of the ultrafiltration membrane to 4-7 years before a new filter is …

From Crisis Pregnancy Centers To Teenbreaks.Com: Anti-Abortion Activism's Use Of Cloaked Websites, Jessie Daniels

Publications and Research

Anti-abortion activists are making use of a deceptive form of propaganda online through cloaked websites that conceal authorship in order to deliberately disguise their political agenda. This deceptive form of online activism is predated and exists alongside another through the use of brick-and-mortar “Crisis Pregnancy Centers.” Anti-abortion, or “pro-life,” activists have long used storefront outposts designated “Crisis Pregnancy Centers” that masquerade as providers of reproductive health services to deceive women who are pregnant into scheduling appointments with them instead of with abortion providers. Once at the “Crisis Pregnancy Centers,” activists then try to convince women seeking an abortion not to …

The Personal And Professional Characteristics Of Master Therapists And Matched Controls, Barbara A. Granville Phd

All Student Scholarship

This dissertation is an attempt to replicate the results of a study conducted by Len Jennings(1996) which provided the data underlying the "cognitive, emotional, and relational" (CER) model of therapist excellence. As outlined in Jennings'(1996) research protocol, data were gathered through semi-structured interviews with ten master therapists chosen through a snowball sampling technique. Unlike the original study, this dissertation includes a matched control group intended to provide insight about the generalizability of the categories/domains of CER.

Cultural Determinants Of Workplace Arbitration In The U.S. And Italy, Ann C. Hodges

Law Faculty Publications

Although Italy and the United States are both advanced industrial economies, the law and practice of workplace arbitration differs significantly in the two countries. This Article explores those variations and analyzes the reasons lbr the divergent evolution of arbitration. The Article concludes that histon'cal and cultural differences in legal systems and labor and employment relations are explanatory forces. While the United States could provide a more balanced system of arbitration by learning from the Italian systems greater protection of workers, given the current reality neither system seems likely to undergo significant change in the near fiiture.

Reports & Public Policy Documents

As the world’s population increases, as global markets become more interconnected, and as the effects of climate change become clearer, the issue of food insecurity is gaining traction at local, national, and international levels. The recent global economic crisis and increased food prices have drawn attention to the urgent situation of the world’s 870 million chronically undernourished people who face the number one worldwide risk to health: hunger and malnutrition. Although about 75% of the world’s undernourished people live in low-income, rural regions of developing countries, hunger is also an issue in Canada. In 2011, 1.6 million Canadian households, or …

Measures Of Written Linguistic Accuracy: Questions Of Reliability, Validity, And Practicality, Troy L. Cox, Norman W. Evans, K. James Hartshorn, Teresa Martin De Jel

Faculty Publications

Determining linguistic improvement in L2 writing requires a precise measure of linguistic accuracy. Although numerous metrics of linguistic accuracy have been used in L2 research, Wigglesworth and Foster (2008) proposed a new kind of measure—a weighted clause ratio—based on the adequacy of the writer’s conveyed meaning. This paper evaluates the validity of this metric and compares it to two of the most similar measures of linguistic accuracy currently in use: the error-free T-unit ratio and the error-free clause ratio. The data collected and analyzed in this study were drawn from over 350 writing samples generated by 81 ESL writers whose …
