Understanding The Mode Of Action Of Essential Oil Nanoemulsions To Inhibit Fusarium Growth And Mycotoxin Production In Cereal, Haiyang Jiang

Plant Sciences

Deoxynivalenol (DON) is a commonly occurred mycotoxin in cereal-based food, which is mainly produced by Fusarium spp. in the field. It is unfeasible to entirely avoid DON contamination in cereal grains with good agricultural practices. Therefore, it is of great importance to have a strategy for preventing DON contamination in our final food products. In recent years, utilization of plant extracts such as essential oils (EOs) as antifungal and mycotoxin inhibitory agents in foods have gained popularity. Depending on the EO type and chemical composition of EOs, the antifungal and mycotoxin inhibitory efficacies of different EOs might be varied. In …

Identification Of Genomic Regions Associated With Color-Related Traits In Durum Wheat, Seyedali Hosseinirad

Plant Sciences

Durum wheat (Triticum turgidum L. ssp. durum Desf.) is one of the main crops for human consumption, and it is an essential ingredient for pasta production. The color of pasta can range from bright yellow to dim brown. Pasta brightness and yellowness are important quality indicators for producers and customers. Releasing durum wheat cultivars capable of producing pasta products with high yellow color can be an important goal for breeders. Yellow pigment content (YPC) is one of the important components that affect pasta color. The yellow color of pasta is not necessarily dictated by the presence of YPC; soluble brown …

Genome-Wide Association Study And Genomic Prediction For Pod Shatter Resistance In Brassica Napus L., Shakil Hosain

Plant Sciences

The release of seeds from a mature dry pod is known as shattering. Pod shattering results in significant yield losses in rapeseed/canola. An experiment was conducted in five environments in 2020 and 2021 under the field and the greenhouse conditions using 150 spring-type Brassica napus genotypes. Genome-wide association study (GWAS) identified 21 significant SNPs for pod shattering using eight different GWAS models. The phenotypic variation explained by these SNPs ranged from 3.8 -25.4%. Three potential candidate genes, IND, AGL65, and MAN7, were identified for the pod shattering. Genomic prediction was done using 14 genomic selection models. The prediction ability for …

Biomass Yield And Nutritive Value Of Annual Forage Mixes Compared With Monocrops, Kenneth Mozea

Plant Sciences

Forage mixes could serve as a cover crop mix to protect the soil during the winter, for prevented planting areas or as a high nutritious feed for grazing livestock. The objective of this study was to determine the nutritive value and productivity of selected annual forage mixes compared with forage sorghum monocrops. The nutritive value of annual forage mixes and monocrops varied across environments and between treatments. Monocultures produced more biomass than annual forage mixes. The three most productive mixes in comparison to the others were hybrid brassica/oat/forage pea/forage sorghum x sudangrass/sweet sorghum blend/foxtail millet, turnip/forage sorghum x sudangrass/sweet sorghum …

Study Of Freezing Tolerance After Cold Acclimation Followed By Deacclimation In Winter And Spring Canola (Brassica Napus L.), Ashok Mandal

Plant Sciences

Winter canola/rapeseed (Brassica napus L.) produced 20 to 30% greater yield over spring canola. It overwinters to flower in spring. The winter type shows increased freezing tolerance after cold acclimation, which is crucial to survive in winter. However, short duration warm spells can cause canola to lose increased freezing tolerance in a process called “deacclimation” making it again vulnerable to freezing damage. We found canola almost completely deacclimated at 13°C or more for at least two days of deacclimation. However, longer duration of deacclimation (7 & 14 days) showed increased freezing tolerance as compared to 2 & 3 days at …

Non-Chemical Weed Management In Annual And Perennial Organic Cropping Systems, Zachary Pull

Plant Sciences

Weedy pests, especially perennial weeds, are among the most challenging barriers to organic crop production. Improving non-chemical weed management tactics for established organic productions systems, like cool-season grains, and emerging crops like perennial flax could benefit producers. We compared three crop sequences for creeping perennial weed suppression in organic grains. Three years of alfalfa was associated with reduced densities and aboveground biomass of perennial weeds compared to sequences that alternated grain and cover crops. Interseeding cover crops with perennial flax for weed management was attempted, but neither flax nor cover established well. Flame weeding and cultivation in perennial flax were …

An Analysis Of The Nba Draft: Are Teams Drafting Better And Does College Experience Truly Matter, Kevin Wolfe

Statistics

This thesis attempts to answer two questions. Are NBA organizations doing a reasonable job at drafting players and getting better at the process, and does college experience play a significant role in a player’s performance during their early NBA career (first 3 seasons).In regard to these two questions, we determined through our research that NBA organizations are not showing any significant improvements in their ability to draft the best available players, this is surprising given the increase in available scouting data teams currently have access to. We suspected however that this lack of drafting improvements may be related to players …

Three Essays On Railroad Safety Analysis Using Non-Parametric Statistical Methods, Neeraj Dhingra

Transportation Logistics and Finance

he FRA mandated railroad companies to install a new monitoring system known as Positive Train Control (PTC). This system overlays sensors, signals, and transponders over existing track and other wayside infrastructure. Technologists designed the system to prevent accidents mainly caused by human negligence and communications. However, PTC will not address track-related defects, which is the second dominant cause of accidents. A new track monitoring system called Railway Autonomous Inspection Localization System (RAILS) was proposed to address track-related accidents. RAILS is based on low-cost sensor technology that identifies defect symptoms, ranks their severity, classifies defect types, and localizes their positions. So, …

Faculty Publications

Teacher preparation programs have been slow to prepare teachers for the online environment, leaving many online teachers needing to learn on the job. However, little research has examined how online teachers grow as educators. One way to better understand this growth is to examine the changes online teachers make in their instruction and their rationales for making them. In this qualitative case study, we surveyed online teachers three times during an academic year regarding their instructional changes. Participants described these changes and categorized them on a modified PICRAT matrix to indicate if the changes made student learning more passive, interactive, …

Evidence On Internal Audit Quality From Transitioning To Remote Audits Because Of Covid-19, Marc Eulerich, Martin Wagener, David A. Wood

Faculty Publications

As in-person audits were banned by governments and by company policies due to the COVID-19 pandemic, internal auditors had to transition to remote audits to perform their work. Based on survey responses of internal auditors who have conducted both remote and in-person audits, we find that internal auditors perceive no difference in the efficiency and effectiveness of and stakeholders’ reliance on results from remote and in-person audits when considering all responses. However, we also find that perceived efficiency and effectiveness increase the more experience internal auditors have with remote audits. Supplemental analyses show that support from the auditee, but not …

The Status Of Robotic Process Automation, Steven A. Harrast, David A. Wood

Faculty Publications

Modern information technology (IT) has greatly expanded the capability of companies to coordinate activities and process large numbers of transactions. Unfortunately, large companies often support thousands of individual applications, and the data necessary for financial reporting is scattered across these applications. As applications and data proliferate, companies must link together the applications and systems, often using spreadsheets and expending significant amounts of time in manual data entry and manipulation. This manual work is slow, expensive, and error prone and lacks useful business insights. Also, the employees who must perform these tasks are often overwhelmed and unsatisfied with the mundane work. …

As Yellowstone National Park celebrates its 150th anniversary as the first such park in the world, it is fascinating to rediscover the records of mountain men and and that the same features that enthrall modern visitors captivated them as well. “Sonder” is the realization that other people with whom we share the mortal coil have lived lives just as complex and wonderous as our own. Americans can no better appreciate this than when they stand in Yellowstone National Park today and marvel at the same grandeur mountain men witnessed two hundred years ago.

Students Coming Prepared To Class? A Review Of The Literature With A Call To Research, Melissa P. Larson, Jace Linnell

Faculty Publications

In this literature review, we show that little attention has been given to pre-class learning in a flipped classroom setting. To support learning, a flipped classroom shifts the learning of basic content from a classroom setting to a pre-class setting, thereby freeing up time within class for more active learning activities. Active learning activities support student-centered learning as peers collaborate with deep application of pre-class learning concepts. Thus, higher-order skills of critical thinking and lifelong learning, which are valued in the accounting education curriculum and profession, can be developed through a flipped classroom pedagogy. However, if pre-class learning is not …

Tax Boycotts, H. Scott Asay, Jacob Thornock, Jeffrey L. Hoopes, Jaron H. Wilde
