Development Of Innovative High-Energy Neutron And Gamma-Ray Shielding Material Based On High Density Cement And Crumb Rubber, Pawitra Aim-O Jan 2017

Development Of Innovative High-Energy Neutron And Gamma-Ray Shielding Material Based On High Density Cement And Crumb Rubber, Pawitra Aim-O

Chulalongkorn University Theses and Dissertations (Chula ETD)

The incorporation of carbon and hydrogen-rich material into radiation shielding material can improve its shielding performance. High-density cement mixed with crumb rubber was studied to be a gamma ray and neutron shielding material. Shielding materials were designed using high-density cement mixed with 5 - 25 vol% of crumb rubber. Monte Carlo N-Particle code was employed to simulate radiation shielding performances of the composed materials. The utilized neutron and photon sources were Am-241/Be and Co-60, respectively. These shielding designs were fabricated and experimentally evaluated on the radiation shielding properties. The cracking mechanism of high-density cement mixed with lead (HDCRL) was also …

Differential Precipitation And Solubilisation Of Proteins, Barry J. Ryan, Gemma K. Kinsella Jan 2017

Differential Precipitation And Solubilisation Of Proteins, Barry J. Ryan, Gemma K. Kinsella

Books/Book Chapters/ Proceedings

Differential protein precipitation is a rapid and economical step in protein purification and is based on exploiting the inherent physicochemical properties of the polypeptide. Precipitation of recombinant proteins, lysed from the host cell, is commonly used to concentrate the protein of choice before further polishing steps with more selective purification columns (e.g., His-Tag, Size Exclusion, etc.). Recombinant proteins can also precipitate naturally as inclusion bodies due to various influences during overexpression in the host cell. Although this phenomenon permits easier initial separation from native proteins, these inclusion bodies must carefully be differentially solubilized so as to reform functional, correctly folded …

Conditions Responsible For The Success Of Carnivorous Plants In Nutrient-Poor Wetlands, Matthew John Abbott Jan 2017

Conditions Responsible For The Success Of Carnivorous Plants In Nutrient-Poor Wetlands, Matthew John Abbott

Electronic Theses and Dissertations

Despite the vast array of past research focused on carnivorous plants, few studies have investigated the ecological interactions between carnivorous and non-carnivorous plant species. I addressed the following three questions: (1) does niche complementarity promote coexistence between fire-adapted carnivorous and non-carnivorous species? (2) do carnivorous plants rely on both leaf traps and arbuscular mycorrhizal fungi to access different nutrients that are in high demand after fire in nutrient poor bogs? (3) why are carnivorous plants largely absent from nutrient-rich wetlands? I addressed the first question by examining the three-way interacting effects of fire, prey-derived nutrient availability, and root competition from …

A Probabilistic Approach To Multiple-Instance Learning, Silu Zhang Jan 2017

A Probabilistic Approach To Multiple-Instance Learning, Silu Zhang

Electronic Theses and Dissertations

This study introduced a probabilistic approach to the multiple-instance learning (mil) problem. In particular, two bayes classication algorithms were proposed where posterior probabilities were estimated under dierent assumptions. The rst algorithm, named instance-vote, assumes that the probability of a bag being positive or negative depends upon the percentage of its instances being positive or negative. This probability is estimated using a k-nn classication of instances. In the second approach, embedded kernel density estimation (ekde), bags are represented in an instance induced (very high dimensional) space. A parametric stochastic neighbor embedding method is applied to learn a mapping that projects bags …

Co2 Adsorption On Volcanic Ash: Net Contribution Of Volcanic Eruptions To The Global Carbon Cycle, Lee New Jan 2017

Co2 Adsorption On Volcanic Ash: Net Contribution Of Volcanic Eruptions To The Global Carbon Cycle, Lee New

Electronic Theses and Dissertations

Adsorption of co2 on mineral surfaces accounts for a small percentage of the terrestrial co2 sink. Volcanic ash is virtually free of co2 when erupted and has a high surface area resulting in a high capacity for co2 adsorption. Volcanism is commonly assumed to be only a source of co2, but pyroclastic eruptions can also potentially serve as a sink. Adsorption was investigated for 6 volcanic ash samples of andesitic composition from four volcanoes: Okmok, Redoubt, Spurr, and Tungurahua. The eruption of volcano redoubt released 0.75 x 109 metric tons of co2 and 55 x 109 kg of ash throughout …

The Impact Of Simulated Microgravity On The Growth Of The Model Legume Plant Medicago Truncatula, Gemma Elizabeth Lionheart Jan 2017

The Impact Of Simulated Microgravity On The Growth Of The Model Legume Plant Medicago Truncatula, Gemma Elizabeth Lionheart

Electronic Theses and Dissertations

Simulated microgravity has been a useful tool to help understand plant development in altered gravity conditions. Thirty-one genotypes of the legume plant Medicago truncatula were grown in either simulated microgravity on a rotating clinostat, or a static, vertical environment. Twenty morphological features were measured and compared between these two gravity treatments. Within-species genotypic variation was a significant predictor of the phenotypic response to gravity treatment in 100% of the measured morphological and growth features. In addition, there was a genotype–environment interaction (G×E) for 45% of the response variables, including shoot relative growth rate (p < 0.0005), median number of roots (p ∼ 0.02), and root dry mass (p < 0.005). These findings are discussed in the context of improving future studies in plants space biology by controlling for genotypic differences, and by connecting traits to their underlying genetic causes by using genome-wide association (GWA) mapping. In the long-term, manipulation of genotype effects, in combination with M. truncatula’s symbiotic relationships with rhizobacteria and arbuscular mycorrhizal fungi, will be important for optimizing legumes for cultivation on long-term space missions.

Risk, Reward, And The Role Of Habitat Selection On Community Dynamics In Temporary Ponds, Matthew Robert Pintar Jan 2017

Risk, Reward, And The Role Of Habitat Selection On Community Dynamics In Temporary Ponds, Matthew Robert Pintar

Electronic Theses and Dissertations

The processes that generate patterns of species diversity within and among habitat patches are a fundamental topic of interest in ecology. Traditionally, there was a focus on post-colonization effects such as predation, however, pre-colonization processes, such as habitat selection, are equally important determinants of community structure. In freshwater systems, the lethal effects of dominant predators (particularly fish) are well established, while the transition from permanent to temporary ponds is a defining characteristic. This transition produces distinct communities characterized by organisms with complex life cycles and plastic developmental strategies. This means that many organisms occupying habitat patches arrive there by the …

Southern Discomfort: Performing Femininity In The Deep South, Rachel Whitney Turnipseed Jan 2017

Southern Discomfort: Performing Femininity In The Deep South, Rachel Whitney Turnipseed

Electronic Theses and Dissertations

The “performance” of gender is variable and multifarious, fabricated in reaction to audience, mood, and previous experiences. Starting in childhood, people “police” our gender performances, and profoundly shape our self-presentation and sense of personal identity. We gradually learn to self-edit our performances of gender, after countless critiques by others, which often negatively impact our body image as they preserve “norms,” marginalizing anyone who does not conform. The mixed-media installation, Southern Discomfort: Performing Femininity in the Deep South, examines this process and its impact on young girls. The young, blonde, female figure who appears multiple times in my installation reveal girls …

Relationships Between Dietary Habits, Demographics, And Hike Outcome Among 2015 Pacific Crest Trail Backpackers, Lauren Ann Black

Electronic Theses and Dissertations

This quantitative research study explores the relationship between dietary patterns, hiker demographics, and total miles hiked during a backpacking trip on the Pacific Crest Trail (PCT). Long hiking distances, low rate of thru-hike completion, consumption of processed and ready to eat foods, weight loss, and large time and monetary strains are comthemes accepted anecdotally by the backpacking population11. However, these themes have yet to be adequately researched and validated for long distance backpackers and PCT backpackers specifically. The online survey gathered data from 151 backpackers who hiked the PCT in 2015. Significant positive correlational relationships were found between the number …

A “Human Endeavor”: Killing In Contemporary U.S. Combat Narratives, William Mackenzie

Electronic Theses and Dissertations

This PH.D dissertation aims to develop a 3-D numerical model of dam-break flows on movable beds. Three tasks are defined to accomplish the goal of this study. The first task is developing a 3-D hydrodynamic model to simulate dam-break flow on fixed beds with simple geometry and test the water surface tracking technique. This model solves the Reynolds-averaged Navier-Stokes (RANS) equations using a finite-difference method on rectilinear, staggered grids. The volume-of-fluid (VOF) technique with SOLA-VOF advection scheme is used to capture the free surface motion. The developed model is tested using several experimental dam-break flows and the VOF technique is …

A Little Difference Makes A Big Difference: Essays On The Link Between Top Management Team Traits And Strategic Marketing Decisions, Cameron Duncan Nicol

Electronic Theses and Dissertations

The importance of marketing is growing. This is not just a perception: CEOs appear to see its importance as well. Despite the increase in the understood importance of marketing, there still remains a relatively scant amount of research on the impact that can be had by top management team members on a firm's strategic marketing outcomes. The research which follows explores an important question that has previously been comparatively neglected by researchers: what top management team individual differences can impact the strategic marketing outcomes of the firm? The first essay, based on a multi-industry sample of 325 publicly listed fortune …

Reverse Passing, Khaled A. Beydoun, Erika K. Wilson Jan 2017

Reverse Passing, Khaled A. Beydoun, Erika K. Wilson

Faculty Articles

Throughout American history untold numbers of people have concealed their true racial identities and assumed a white racial identity in order to reap the economic, political, and social benefits associated with whiteness. This phenomenon is known as passing. While legal scholars have thoroughly investigated passing in its conventional form, the corollary process of reverse passing—the process in which whites conceal their true racial identity and present themselves as nonwhite—has not been closely investigated within legal scholarship. Rachel Dolezal provides a timely study of the process of reverse passing. Dolezal—an Africana Studies Instructor and head of the Spokane, Washington NAACP—was outed …

Cost-Benefit Analysis And The Structure Of The Administrative State: The Case Of Financial Services Regulation, Richard L. Revesz Jan 2017

Cost-Benefit Analysis And The Structure Of The Administrative State: The Case Of Financial Services Regulation, Richard L. Revesz

Faculty Articles

The viability and desirability of conducting cost-benefit analysis of financial regulation is a subject of intense academic debate. Opponents claim that such analysis is feasible for environmental regulation but not for financial regulation because of the difference in the benefits that require monetization in the respective areas. This Article argues that the recent debate misses an important part of the problem. In large part, cost-benefit analysis of financial regulation cannot currently be performed successfully because of institutional shortcomings, not analytical difficulties. Compared to Executive Branch agencies, independent agencies, like the major financial regulatory agencies, lack the capacity to do cost-benefit …

The Unregulated Certification Mark(Et), Jeanne C. Fromer Jan 2017

The Unregulated Certification Mark(Et), Jeanne C. Fromer

Faculty Articles

Certification mark law — a branch of trademark law — itself enables consequences that undermine the law’s own goals through inadequate regulation or oversight. Because the law allows certification standards to be kept vague, high-level, and underdeveloped, a certifier can choose to exclude certain businesses inconsistently or arbitrarily, even when those businesses’ goods or services would seem to qualify for the certification mark (particularly to consumers). Moreover, even when a certification standard is clear and complete, certifiers can wield their marks anticompetitively. They can do so through redefinition — something certification mark law currently allows without oversight — to ensure …

Limitless Worker Surveillance, Ifeoma Ajunwa, Kate Crawford, Jason M. Schultz

Faculty Articles

From the Pinkerton private detectives of the 1850s, to the closed-circuit cameras and email monitoring of the 1990s, to new apps that quantify the productivity of workers, and to the collection of health data as part of workplace wellness programs, American employers have increasingly sought to track the activities of their employees. Starting with Taylorism and Fordism, American workers have become accustomed to heightened levels of monitoring that have only been mitigated by the legal counterweight of organized unions and labor laws. Thus, along with economic and technological limits, the law has always been presumed as a constraint on these …
