Optimization And Analytics Of Decarbonized Forest And Biomass Supply Chains, Xufeng Zhang

Graduate Theses, Dissertations, and Problem Reports

First, a data-driven holistic analysis framework was developed to aid the industrial development of forest biomass for bioenergy to promote the regional bioeconomy. Leveraging the existing but fragmented multi-source data, four components of industrial bioenergy development were integrated into the framework including spatial statistical analysis of biomass feedstock and bioenergy production, machine learning-based suitability assessment, bioenergy plant sites identification and ranking, and socio-economic impacts assessment. A case study was conducted for forest biomass to pellet fuel in the U.S. Mid-Atlantic region. Our results indicate that the great potential of forest biomass with high variation at the county level is primarily …

Analyzing The Viability Of Direct Pcr For Use In Conjunction With Cyanoacrylate Enhanced Fingerprints, Coral M. Smith

Graduate Theses, Dissertations, and Problem Reports

Efficient methods for DNA analysis are desperately needed in laboratories due to the influx in DNA analysis requests. The current DNA processing methods are costly, time consuming, and involve multiple tube changes, increasing the risk of contamination. However, the use of direct PCR can simplify the DNA analysis process by eliminating the extraction, purification and quantitation steps. Presently, the FBI Quality Assurance Standard 9.4 requires all evidence samples to be quantitated. As a result, the direct PCR method of DNA processing cannot be implemented on evidence samples at this time. Direct PCR presents the opportunity to provide efficient DNA analysis, …

Mtdna Heteroplasmy In Hair Shafts Versus Buccal Swabs For Forensic Applications, Sara R. Bodnar

Graduate Theses, Dissertations, and Problem Reports

Mitochondrial DNA (mtDNA) analysis has several forensic applications such as criminal investigations, identification of human remains, and missing person investigations. It is also the only type of DNA that is available from certain sample types such as hair shafts. The presence of mtDNA heteroplasmy within and between tissue types can lead to mtDNA sequence differences when comparing samples originating from the same individual. Studies on mtDNA heteroplasmy are increasingly being carried out for their implications in forensic interpretation of mtDNA sequences. Specifically, mtDNA in buccal swabs compared to hair samples from one individual may show differences in sequence due to …

Sleep And Cardiovascular Reactivity To An Acute Virtual Stressor, Alaina Grace Tiani

Graduate Theses, Dissertations, and Problem Reports

Inappropriate response and magnitude of cardiovascular reactivity (CVR) to stress is a proposed mechanism through which environmental stressors are linked with poor cardiovascular health outcomes (Chida & Steptoe, 2010; Krantz & Manuck, 1984). Studies of reactivity to various laboratory tasks commonly control for factors known to influence CVR such as smoking, medication use, caffeine intake, and BMI; however, few have considered the influence of sleep on CVR. In order to determine whether sleep characteristics need to be assessed and considered in studies of CVR, this study aimed to examine the association between indices of sleep quality and the magnitude and …

Psychosocial Influences On And Behavioral Characteristics Of Young Adult Food Addiction, Rachel A. Wattick

Graduate Theses, Dissertations, and Problem Reports

Introduction. Research on food addiction has increased in recent years, but there are few studies focusing on college-attending young adults, who may be at risk of developing food addiction due to the stress of the college environment. Additionally, causes and characteristics of food addiction are under-explored.

Aim. This dissertation aims to 1) determine the impact of adverse childhood experiences (ACEs) and other early life influences on the development of food addiction in college-attending young adults and 2) determine the psychosocial and behavioral characteristics of young adults with food addiction.

Methods. A sequential explanatory mixed-methods design was used for aims 1 …

The Process And Case Study Approach To Implementing A Nutrition-Specific Dissemination And Implementation Science Training In Appalachia, Ayron E. Walker

Graduate Theses, Dissertations, and Problem Reports

Introduction: Nutrition professionals face implementation challenges due to their lack of knowledge to incorporate D&I science into intervention design. To improve intervention outcomes, nutrition professionals must be trained in D&I science, which are currently absent in the field.

Aims: To identify and assess nutrition educators and practitioners perceived motivations, self-efficacy, and attitudes in using D&I science to inform the educational design and strategies of a nutrition-specific D&I curriculum for nutrition educators. Then to test feasibility of the nutrition-specific curriculum in increasing knowledge, self-efficacy, and attitudes by a case study approach, pre/post intervention design.

Methods: First, scoping review methodology involved the …
