Effect Of Volunteer Corn Density On Deoxynivalenol Production By Fusarium Graminearum In Hybrid Corn, Gaelle Florence Hollandbeck

Open Access Theses

Fusarium graminearum causes Gibberella ear rot in corn and produces mycotoxins such as deoxynivalenol (DON). Volunteer corn is a weed resulting from uncollected kernels from the previous harvest and is very difficult to control once established. An experiment was established in Porter County, IN from 2013 to 2015 to examine the impact of volunteer corn density on Gibberella ear rot severity and DON levels in hybrid corn. Five densities of volunteer corn were established within plots of each hybrid (0, 0.5, 2, 4, and 8 volunteer plants/m2). Disease severity and DON were assessed for both hybrid and volunteer ears collected …

Open Access Dissertations

This dissertation presents the findings from three participatory focus group and co-design sessions with Caribbean transmigrant women in the United States. Informed by their focus group discussions regarding their pregnancy experiences in the United States, the participants produced design ideas that reflected on physical, emotional, informational and social gap themes. The purpose of this study was to understand the challenges affecting the women’s prenatal wellbeing practices, and to conceive a set of recommendations and opportunities for mHealth technology design to assist with prenatal preventative care and management. The study uses the theoretical concept of pregnancy ecology to identify gaps in …

Supervised Learning-Based Explicit Nonlinear Model Predictive Control And Unknown Input Estimation In Biomedical Systems, Ankush Chakrabarty

Open Access Dissertations

Application of nonlinear control theory to biomedical systems involves tackling some unique and challenging problems. The mathematical models that describe biomedical systems are typically large and nonlinear. In addition, biological systems exhibit dynamics which are not reflected in the model (so-called 'un-modeled dynamics') and hard constraints on the states and control actions, which exacerbate the difficulties in designing model-based controllers or observers.

This thesis investigates the design of scalable fast explicit nonlinear model predictive controllers (ENMPCs). The design involves (i) the estimation of a feasible region using Lyapunov stability methods and support vector machines; and (ii) within the estimated feasible …

A Flexible And Versatile Framework For Statistical Design And Analysis Of Quantitative Mass Spectrometry-Based Proteomic Experiments, Meena Choi

Open Access Dissertations

Quantitative mass spectrometry (MS)-based proteomics is an indispensable technology for biological and clinical research. As the proteomics field grows, MS-based proteomic workflows are becoming more complex and diverse. The accuracy and the throughput of the MS measurements and of the signal processing tools dramatically increased. However, many existing statistical tools and workflows have not followed the technological development. Therefore, there is a need for flexible statistical tools, which reflect diverse and complex workflows, are computationally efficient for large datasets, and maximize the reproducibility of the results.

We propose a family of linear mixed effects models, and a split-plot view of …

The Effects Of Acidified Pepsin On Porcine Vocal Fold Tissue: Developing A Porcine Model Of Laryngopharyngeal Reflux Disease, Abigail Cox Durkes

Open Access Dissertations

Approximately 7.5 million Americans are affected by a voice disorder. In the last year, 7.2% of people missed one or more days of work due to a voice problem. For professional voice users, such as teachers, the rate increases to 20% and an annual cost of $2.5 billion. Voice disorders are complex and multi-faceted, as well as difficult to diagnose and treat. Prospective animal studies are necessary to study the pathophysiology of voice disorders, optimize our understanding of laryngeal pathology, and improve treatment outcomes. The pig provides a unique opportunity to test hypotheses relating to laryngeal disease because porcine vocal …

Endonuclease Activities Of Mutlα And Its Homologs In Dna Mismatch Repair., Lyudmila Y Kadyrova, Farid A Kadyrov

Articles

MutLα is a key component of the DNA mismatch repair system in eukaryotes. The DNA mismatch repair system has several genetic stabilization functions. Of these functions, DNA mismatch repair is the major one. The loss of MutLα abolishes DNA mismatch repair, thereby predisposing humans to cancer. MutLα has an endonuclease activity that is required for DNA mismatch repair. The endonuclease activity of MutLα depends on the DQHA(X)2E(X)4E motif which is a part of the active site of the nuclease. This motif is also present in many bacterial MutL and eukaryotic MutLγ proteins, DNA mismatch repair system factors that are homologous …

Sustainability Of Crop Production From Polluted Lands, P. C. Abhilash, Vishal Tripathi, Sheikh Edrisi, Rama Dubey, Mansi Bakshi, Pradeep Dubey, H. B. Singh, Stephen Ebbs

Publications

Sustainable food production for a rapidly growing global population is a major challenge of this century. In order to meet the demand for food production, an additional land area of 2.7 to 4.9 Mha year ^-1 will be required for agriculture. However, one third of arable lands are already contaminated, therefore the use of polluted lands will have to feature highly in modern agriculture. The use of such lands comes however with additional challenges and suitable agrotechnological interventions are essential for ensuring the safety and sustainability of relevant production system. There are also other issues to consider such as, cost …

Perceptions And Predictors Of Questionable Research Practices In The Biological Sciences, Anita M. Gordon, Helen C. Harton

Faculty Work

A nationally representative sample of 429 biology researchers (40% response rate) from 107 R1 and masters universities assessed the features of six research scenarios and reported the probability they would take the same (questionable) action as the actor in the scenario. Results suggest that individual factors such as moral judgment and perceived internal and external consequences may play a larger role in research misbehavior than perceptions of organizational justice or other features of the research environment.

The Virtue Mentality, Rachel Eckhardt

Dissertations, Theses, and Capstone Projects

In my study of early feminist fiction and contemporary queer intentional communities, highly ambitious and nearly impossible aspirations emerged as a singular uniting theme. From early feminist novelists to the intrepid founders of lesbian lands, utopian women share a passionate commitment to transform the world. This thesis engages with feminist concepts of virtue and how they influence utopian projects in both fiction and in life, whether the word “virtue” itself is used to describe the project or not. Virtue has made a lasting impact on contemporary feminist utopian projects that sometimes creates conflict and often undermines its liberatory aspirations. When …

Stress And Suicidal Behavior: A Cognitive, Behavioral, And Biological Integrative Approach, Jorge Valderrama

Dissertations, Theses, and Capstone Projects

Suicide is one of the leading causes of death in young adults in the United States. Previous research has established distal and proximal life stress as a strong risk factor for suicidal behavior. However, how stress impacts suicidal behavior via interactive cognitive and biological mechanisms has not been thoroughly examined. The present research sought to better understand the relationship between stress and suicidal behavior via altered neurobiological functioning, maladaptive cognitions, and deficits in executive functioning. The first study found a relationship between the brooding subtype of rumination and trait impulsivity in the forms of negative urgency, lack of premeditation, and …

It has found successful applications in a variety of fields such as computational biology, neuroscience, natural language processing, information retrieval, image processing and speech recognition. In bioinformatics, for example, it has been used to extract patterns and profiles from genomic and text-mining data as well as in protein sequence and structure analysis. While the scientific performance of NMF is very promising in dealing with high dimensional data sets and complex data structures, its computational cost is high and sometimes could be critical for …

Research Software Sustainability: Report On A Knowledge Exchange Workshop, Simon Hettrick

Copyright, Fair Use, Scholarly Communication, etc.

Without software, modern research would not be possible. Understandably, people tend to marvel at results rather than the tools used in their discovery, which means the fundamental role of software in research has been largely overlooked. But whether it is widely recognised or not, research is inexorably connected to the software that is used to generate results, and if we continue to overlook software we put at risk the reliability and reproducibility of the research itself. The adoption of software is accompanied by new risks - many of which are unknown to the majority of the research community. The practices …

Mcra Gene Abundance Correlates With Hydrogenotrophic Methane Production Rates In Full-Scale Anaerobic Waste Treatment Systems, R. L. Morris, Vaibhav Panjabrao Tale, P. P. Mathai, Daniel Zitomer, James Maki

Biological Sciences Faculty Research and Publications

Anaerobic treatment is a sustainable and economical technology for waste stabilization and production of methane as a renewable energy. However, the process is under-utilized due to operational challenges. Organic overload or toxicants can stress the microbial community that performs waste degradation, resulting in system failure. In addition, not all methanogenic microbial communities are equally capable of consistent, maximum biogas production. Opinion varies as to which parameters should be used to monitor the fitness of digester biomass. No standard molecular tools are currently in use to monitor and compare full-scale operations. It was hypothesized that determining the number of gene copies …

From Patient Rights To Health Justice: Securing The Public's Interest In Affordable, High-Quality Health Care, Lindsay F. Wiley

Cardozo Law Review

Models emphasizing professional autonomy, patient rights, market power, and health consumerism are no longer adequate to address the increasingly social, collective nature of health law institutions, instruments, and norms. What is needed is a new model that expressly recognizes the public - alongside the patient, the provider, and the payer - as an important stakeholder and active participant in decisions about medical treatment, health care coverage, and allocation of scarce resources. In a previous article, the author looked to the environmental justice, reproductive justice, and food justice movements for inspiration in developing a "health justice" approach to eliminating social disparities …

These systems consist of microbial fuel cells (MFCs) whose anode component will be evaluated with regards to performance, electrical current generation, and microbial coverage and biofilm development. …

Cancer Experience Modulates The Relationship Between Child And Parent Hypothalamic Pituiatary Adrenal (Hpa) Axis Functioning, Sarah Dinces

Psychology ETDs

Objective: We examine how parental stress and pediatric cancer might jointly predict child HPA function using a non-invasive method of cortisol assessment (hair samples). Methods: Parents and children from healthy control and pediatric cancer survivor families participated. Multilevel modeling was applied to data from a nested-design study (85 children, 5-18 years old, from 64 families, healthy controls: n=32; cancer survivors: n=32) to determine the relationship between parent salivary and child hair cortisol measures. Results: No main effect of the cancer experience on child cortisol was found. Parental cortisol positively correlated with child cortisol levels within healthy controls, while there was …
