An Analysis Of Signaling Processes Leading To A Defense Response In Soybean, Brandon Trey Mcneece Dec 2017

An Analysis Of Signaling Processes Leading To A Defense Response In Soybean, Brandon Trey Mcneece

Theses and Dissertations

Plant-parasitic nematodes are the cause of devastating yield loss in vital agricultural crops around the world. Heterodera glycines, also referred to as soybean cyst nematode, is the main pathogen of Glycine max (soybean) causing more loss than all other pathogens of G. max combined. The resultant economic impact due to H. glycines in United States soybean production alone is estimated to account for an annual one-billion-dollar loss. Natural resistant genotypes have been found in trials to combat this pathogen. Of the resistant varieties identified, G. max[Peking/PI 548402] and G. max[PI 88788] are the major sources of resistance. Identification of genes …

Introducing New Energy Dissipation Mechanisms For Steel Fiber Reinforcement In Ultra-High Performance Concrete, Dylan Andrew Scott Dec 2017

Introducing New Energy Dissipation Mechanisms For Steel Fiber Reinforcement In Ultra-High Performance Concrete, Dylan Andrew Scott

Theses and Dissertations

By adding annealed plain carbon steel fibers and stainless steel fibers into Ultra-High Performance Concrete (UHPC), we have increased UHPC’s toughness through optimized thermal processing and alloy selection of steel fiber reinforcements. Currently, steel fiber reinforcements used in UHPCs are extremely brittle and have limited energy dissipation mainly through debonding due to matrix crumbling with some pullout. Implementing optimized heat treatments and selecting proper alternative alloys can drastically improve the post-yield carrying capacity of UHPCs for static and dynamic applications through plastic deformations, phase transformations, and fiber pullout. By using a phase transformable stainless steel, the ultimate flexural strength increased …

Management Practices For Corn Producers Implementing Early Planting As A Production Strategy, Matthew W. Hock Dec 2017

Management Practices For Corn Producers Implementing Early Planting As A Production Strategy, Matthew W. Hock

Theses and Dissertations

Producers choosing to implement an early corn planting management strategy often experience several yield limiting biotic and abiotic factors. Field variability, flooding, sub-optimal soil temperatures which leads to poor nutrient uptake, delayed emergence and reduced root growth can limit grain production. Three separate experiments were conducted to address some of the negative effects associated with early corn planting. Experiment 1 evaluated flooding effects on several morpho-physiological traits including root system architecture during early crop development. Hybrids (DKC 6208, Pioneer 1197) were flooded at planting (V0) and growth stages V1, V2, V3 for 0, 6, 12, 24, 48, 96 hours. Plants …

Exploring The Determinants Of Vulnerable Road Users' Crash Severity In State Roads, Àlvaro Alfonso Caviedes Cómbita

Dissertations and Theses

Pedestrians and bicyclists are the most vulnerable road users and suffer the most severe consequences when crashes take place. An extensive literature is available for crash severity in terms of driver safety, but fewer studies have explored non-motorized users' crash severity. Furthermore, most research efforts have examined pedestrian and bicyclist crash severity in urban areas. This study focuses on state roads (mostly outside major urban areas) and aims to identify contributing risk factors of fatal and severe crashes involving pedestrians and bicyclists in state roads. Two ordinal regression models were developed (one for pedestrian and the other for bicyclist crashes) …

Session 4 Presentation - Improved Coastal And Nearshore Wave Forecasting, Jeffrey Hanson, Robert Fratantonio Dec 2017

Session 4 Presentation - Improved Coastal And Nearshore Wave Forecasting, Jeffrey Hanson, Robert Fratantonio

Ocean Waves Workshop

Accurate nearshore and coastal wave forecasts are essential for the protection of life and property as well as enhancing the economy through safe and efficient commercial activities. Modeling the nearshore environment has remained both computationally intensive and challenging due to the strong interaction of waves with the ocean bottom in shallow water environments. Here we develop a new wave system approach for nearshore wave modeling that addresses these issues. Wave systems result from specific wind forcing events on the ocean surface. This approach extends earlier work on wave system partitioning and tracking to assimilate coastal buoy observations into model output …
