Multi-Level Characterization Of Plasticity, Fracture, And Phase Transformation In Metals With Hexagonal Close-Packed Structure, Evgenii Vasilev
Multi-Level Characterization Of Plasticity, Fracture, And Phase Transformation In Metals With Hexagonal Close-Packed Structure, Evgenii Vasilev
Doctoral Dissertations
In this thesis, contributions to characterization of plasticity, fracture, and phase transformation in metals with hexagonal close-packed structure are presented. First, the structure-properties correlations are established for Mg-1.3Zn-0.4Ca-0.4Mn and Mg-1.5Nd alloys. Next, the role of microstructural features such as gran/twin boundaries in the development of damage and fracture in magnesium is discussed. Then, a structure metric for quantitative assessment of fracture is developed and validated on magnesium and titanium alloys. Experimental studies on plasticity are followed by crystal plasticity modelling of Taylor impact test on zirconium to correlate experimental and predicted evolution of microstructure and shape change. Finally, a phase …

The Layer That Did Not Swim Away: Broadband Acoustic Discrimination And Characterization Of Ocean Stratification, Elizabeth Reed-Weidner
Doctoral Dissertations
Ocean stratification plays a critical role in many oceanographic processes. The magnitude of mixing between stable water masses is regulated, in part, by the intensity of stratification. As such, stratification modulates the vertical transport of heat and many important dissolved constituents in the water column, influencing such processes as ocean ventilation, and ocean heat and carbon uptake. As human induced climate change alters oceanic stratification a thorough understanding of its distribution and variability is critical in the study of the world’s oceans. However, traditional methods are limited in terms of spatial context and rapid, near-synoptic observational methods, such as those …

The maps are …
Influence Of Permafrost Thaw, Microtopography, And Precipitation On Methane Cycling In Northern Peatlands, Clarice Rachelle Perryman
Influence Of Permafrost Thaw, Microtopography, And Precipitation On Methane Cycling In Northern Peatlands, Clarice Rachelle Perryman
Doctoral Dissertations
Northern peatlands are both globally important carbon (C) stores and sources of methane (CH4). The impacts of climate change including warming, changing precipitation and hydrology, shifts in vegetation, and thawing permafrost may increase the vulnerability of the northern peatland C stock, including the amount of C lost to the atmosphere as CH4. Variation in peatland water table depth strongly influences CH4 cycling, as water table levels largely control redox conditions and therefore rates of anaerobic CH4 production (methanogenesis) and aerobic CH4 oxidation (consumption, methanotrophy). As CH4 emissions reflect the balance of methanogenesis and methanotrophy, changes in water table depth due …

Data Catalog
Jeffreys Ledge is a major physiographic feature in the western Gulf of Maine (WGOM) located ~50 km off the coast of New Hampshire, although coming within ~10 km of shore by Cape Ann, Massachusetts. Jeffreys Ledge rises up as much as ~150 m from the seafloor of the adjacent basins (i.e., Scantum Basin or Wilkinson Basin) to depths less than 50 m on the ridge surface. The ridge extends over 100 km along its north-northeast to south-southwest axes while generally only being 5 to 10 km in width (~20 km maximum). Jeffreys Ledge and the surrounding region, like many features …

Data Catalog
An approximately 4.5 km transect running from lower Portsmouth Harbor seaward onto the inner continental shelf was established to serve as the field site for the Newcastle Backscatter Experiment (NEWBEX). Acoustic backscatter measurements were made along the transect to examine relationships between backscatter and seafloor properties. This transect takes advantage of the diversity and heterogeneity of bottom types in lower Portsmouth Harbor and approach. In support of NEWBEX, a field campaign was undertaken to describe the sedimentologic characteristics of the seafloor along the transect. A total of five cruises were carried out approximately seasonally on November 26, 2012 and June …

Reduction Of Antipsychotic Use In Patients With Dementia Residing In Nursing Homes, Marysarah Frank
DNP Scholarly Projects
Abstract
Residents of nursing homes diagnosed with dementia have long been treated with psychotropic drugs for the symptoms of behavioral disturbances that are frequently associated with major neurocognitive disease. Specifically, the antipsychotic drugs have been widely used in this population. Despite a lack of evidence, antipsychotic rates have shown up to 25% of dementia patients in nursing homes (NH) are prescribed these drugs. This off-label use is not FDA approved for behavioral symptoms of dementia and the drugs have been given a black box warning related to the risk of serious and potentially irreversible side effects and even an increased …

Crystallization is the most serious bottleneck in high-throughput protein-structure determination by diffraction methods. We have used data mining of the large-scale experimental results of the Northeast Structural Genomics Consortium and experimental folding studies to characterize the biophysical properties that control protein crystallization. This analysis leads to the conclusion that crystallization propensity depends primarily on the prevalence of well-ordered surface epitopes capable of mediating interprotein interactions and is not strongly influenced by overall thermodynamic stability. We identify specific sequence features that correlate with crystallization propensity and that can be used to estimate the crystallization probability of a given construct. Analyses of …

Mood experience is comprised of at least two elements: the direct experience of the mood and a meta-level of experience that consists of thoughts and feelings about the mood. In Study 1, a two-dimensional structure for the direct experience of mood (Watson & Tellegen, 1985) was tested for its fit to the responses of 1,572 subjects who each completed one of the three different mood scales, including a brief scale developed to assist future research. The Watson and Tellegen structure was supported across all three scales. In Study 2, meta-mood experience was conceptualized as the product of a mood regulatory …
