Dry Reforming Of Methane In Palladium-Silver-Copper Alloy Membrane Reactor, Sarocha Sumrunronnasak
Chulalongkorn University Theses and Dissertations (Chula ETD)
PdAgCu ternary alloy membranes were prepared by the sequential electroless plating of Pd following by electroplating of Ag and Cu onto stainless steel support. The metal composition of the membrane was varied by changing the metal deposition times. The fabricated membranes were then annealed at various temperatures from 500 °C to 600 °C under argon atmosphere in order to form the alloys for 20 to 120 hrs. The Energy Dispersive X-ray spectroscopy (EDX) and X-Ray Diffraction (XRD) were employed to investigate the element distribution in the membrane which provided the insight of the alloying formation. Complete formation of the alloy …

Preparation Of Polylactide/ Polycaprolactone/Hydroxyapatite Particles, Walaiporn Nguantanom
Chulalongkorn University Theses and Dissertations (Chula ETD)
This research focused on preparation of polylactide/polycaprolactone/hydroxyapatite particles by using the solvent evaporation method. The effects of HA loadings varied in a range of 10-40 wt% and blending ratios between PLA and PCL on the size distribution, morphology, and thermal properties of the composite films were investigated. The results showed that the size distributions of the composite particles were composed of both small and large particles, depending on the HA concentration and blending ratio of PLA/PCL. The addition of HA at 10 wt% exhibited a strong influence on the size distribution of microspheres, while the PLA/PCL blend tended to produce …

Laboratory Investigation And Numerical Modelling Of Track Foundation For High-Speed Railway Construction On Bangkok Soft Soil, Phitsanu Pholkainuwatra
Chulalongkorn University Theses and Dissertations (Chula ETD)
The government of Thailand has recently decided to launch a high-speed railway project to promote regional economy and improve the logistics of trade to connect with other countries in Southeast Asia community. Raising a complication regarding the load transfers will certainly induce many problems to the railway system. Moreover, the constructions of railway substructures in the past often involve the low quality of materials especially in the Central Plain of Thailand. Therefore, it is necessary to determine the sources of construction materials for railway substructure materials. This study consists of two main objectives. The first objective is to investigate the …
Unidirectional Lasing Emerging From Frozen Light In Nonreciprocal Cavities, Hamidreza Ramezani, S. Kalish, I. Vitebskiy, T. Kottos
Unidirectional Lasing Emerging From Frozen Light In Nonreciprocal Cavities, Hamidreza Ramezani, S. Kalish, I. Vitebskiy, T. Kottos
Physics & Astronomy Faculty Publications
We introduce a class of unidirectional lasing modes associated with the frozen mode regime of nonreciprocal slow-wave structures. Such asymmetric modes can only exist in cavities with broken timereversal and space inversion symmetries. Their lasing frequency coincides with a spectral stationary inflection point of the underlying passive structure and is virtually independent of its size. These unidirectional lasers can be indispensable components of photonic integrated circuitry.
Vanishing Power Lines And Emerging Distributed Generation, Gina S. Warren
Vanishing Power Lines And Emerging Distributed Generation, Gina S. Warren
Faculty Scholarship
Experts predict that distributed energy will contribute as much as twenty percent of the U.S. power supply by 2020. While no one will wake up tomorrow morning to an entirely new energy distribution system — complete with solar panels on the roof and a wind turbine in the back yard — distributed generation is receiving significant attention as the disruptive technology that will ultimately revolutionize the way energy is delivered in the United States. The reason for this shift is, in part, due to new technology that allows for more flexible localized generation of energy, and in part due to …

The morphology of galaxies can be quantified to some degree using a set of scale-invariant parameters. Concentration (C), asymmetry (A), smoothness (S), the Gini index (G), the relative contribution of the brightest pixels to the secondorder moment of the flux (M20), ellipticity (E), and the Gini index of the second-order moment (GM) have all been applied to morphologically classify galaxies at various wavelengths. Here, we present a catalog of these parameters for the Spitzer Survey of stellar structure in Galaxies, a volume-limited, near-infrared (NIR) imaging survey of nearby galaxies using the 3.6 and 4.5μm channels of the Infrared Array Camera …
Impacts Of Invasive Species On Ecosystem Energy Flow On The Big Island Of Hawai'i: Excuse Me, But Are You Going To Eat That Cane Toad?, Erin F. Abernethy, Kelsey L. Turner, James C. Beasley, Travis L. Devault, William C. Pitt, Olin E. Rhodes Jr.

United States Department of Agriculture Wildlife Services: Staff Publications
Worldwide, it has been estimated that invasive species have negative economic impacts in the billions of dollars, with impacts to island ecosystems being among the most devastating. While it is estimated that the most costly and destabilizing impacts are upon ecosystem functions, such impacts are difficult to quantify monetarily, and exact mechanisms are poorly understood. In particular, the role invasive species play in altering energy flow through ecosystems, specifically regarding the recycling of nutrients associated with carrion, is poorly elucidated for most invasive vertebrates. How invasive amphibians and reptiles, which comprise the majority of the invasive species biomass in island …
Report To The Chicago Park District On Conflicts With Ring-Billed Gulls And The 2014 Integrated Ring-Billed Gull Damage Management Project, M. L. Bloomquist, J.W. Hartmann, T.G. Guerrant, S. F. Beckerman, R. M. Engeman
Report To The Chicago Park District On Conflicts With Ring-Billed Gulls And The 2014 Integrated Ring-Billed Gull Damage Management Project, M. L. Bloomquist, J.W. Hartmann, T.G. Guerrant, S. F. Beckerman, R. M. Engeman
United States Department of Agriculture Wildlife Services: Staff Publications
The large ring-billed gull (Larus delawarensis) population in the City of Chicago has caused various conflicts including general nuisance, property damage, economic losses, and threats to human health and safety. Several studies have shown a relationship between ring-billed gulls and increased levels of fecal indicator bacteria (FIB) such as Escherichia coli (E. coli) in nearshore waters. Results of tests for E. coli have led to the issuance of swim advisories at Chicago beaches.
The objectives of the Chicago Ring-billed Gull Damage Management Project were to (1) reduce the local production of ring-billed gulls, (2) reduce the …
Evaluating Seadust Wildlife Controllant™ As A Repellent To Reduce Deer Browse On Douglas-Fir Seedlings, Jimmy D. Taylor Ii
Evaluating Seadust Wildlife Controllant™ As A Repellent To Reduce Deer Browse On Douglas-Fir Seedlings, Jimmy D. Taylor Ii
United States Department of Agriculture Wildlife Services: Staff Publications
Herbivory by black-tailed deer affects growth form and survival of conifer seedlings in western Oregon and Washington, especially Douglas-fir. Several deterrents have been employed to reduce damage to forest resources yet most are ineffective or cost prohibitive. Use of chemical repellents is socially appealing because they offer a potential non-lethal alternative to reduce plant damage (i.e., browse). Commercial deer repellents may employ one or more mechanisms in their formulation, which affect taste, odor, visual, and/or tactile cues when consumed by deer. I evaluated the commercial SeaDust Wildlife Controllant™ as a tool to repel black-tailed deer from Douglas-fir seedlings during spring …
Potential Use Of Perennial Sunflower To Reduce Blackbird Damage To Sunflower, George M. Linz, Brent Hulke, Michael Kantar, Jeffrey Homan, Robert Stupar, Donald Wyse
Potential Use Of Perennial Sunflower To Reduce Blackbird Damage To Sunflower, George M. Linz, Brent Hulke, Michael Kantar, Jeffrey Homan, Robert Stupar, Donald Wyse
United States Department of Agriculture Wildlife Services: Staff Publications
Wildlife Conservation Sunflower Plots (WCSP) have shown potential to reduce blackbird (Icteridae) damage in commercial sunflower. Also known as lure, decoy, or trap crops, WCSP are strategically placed food plots that provide an easily available and proximate food source that entices blackbirds away from valuable commercial crops. By providing an alternative food source, WCSP reduce direct damage to commercial fields, while also lowering indirect costs that producers incur attempting to prevent blackbird damage. However, cost inefficiencies have deterred widespread use of WCSP. Cost-benefit ratios of using WCSP would be greatly improved if a perennial sunflower were used instead of the …
Effectiveness Of Foliar Applications Of 9,10-Anthraquinone For Reducing Blackbird Damage To Sunflower, George M. Linz, Scott J. Werner, Megan Niner, Jeffrey Homan
Effectiveness Of Foliar Applications Of 9,10-Anthraquinone For Reducing Blackbird Damage To Sunflower, George M. Linz, Scott J. Werner, Megan Niner, Jeffrey Homan
United States Department of Agriculture Wildlife Services: Staff Publications
Anthraquinone is an effective chemical seed repellent that protects newly planted crops from depredation by granivorous birds. We are experimenting with foliar applications of 9,10-anthraquinone (AQ) to reduce blackbird (Icteridae) damage to ripening sunflower. Sunflower heads generally turn downward as the achenes mature. With the methods currently available for spraying crops, application of AQ directly onto sunflower achenes is nearly impossible. Blackbirds sometimes remove sunflower bracts prior to eating achenes. Thus, getting AQ droplets directly on the achenes may not be necessary, and spraying the heads should expose blackbirds to AQ as they remove bracts. Studies using caged red-winged blackbirds …

Invasive Black Spiny-Tailed Iguanas (Ctenosaura Similis) On Gasparilla Island, Florida, Usa, Michael L. Avery, Eric A. Tillman, Conny Spurfeld, Richard M. Engeman, Kelin P. Maciejewski, Jessica D. Brown, Emily A. Fetzer
United States Department of Agriculture Wildlife Services: Staff Publications
The native range of Ctenosaura similis extends from southern Mexico through Panama. From an initial introduction of 3 animals in 1979, the species now numbers in the thousands on Gasparilla Island in southwest Florida. In response to complaints of property damage from residents and threats to native species, local officials and the US Department of Agriculture Wildlife Services began a removal program in 2008. Through 2011, trappers removed 9467 ctenosaurs. The number removed declined from 32 iguanas/day in 2008 to 1.9 iguanas/day in 2011 despite no easing of the control effort. We necropsied 2757 ctenosaurs to document aspects of their …

The issue of food insecurity affects millions of people in the United States every year. Often these people rely on soup kitchens, food banks, and shelters for proper meals, and these organizations often depend on donations to meet needs. One of the most limited food resources is meat. To help alleviate this problem, the U.S. Department of Agriculture Wildlife Services donates more than 60 tons of wild game (deer, moose, feral hogs, goats, geese, and ducks) to a variety of charitable organizations each year. Although commercially produced meat routinely undergoes screening for contaminants, potential exposure to environmental contaminants from eating …

Effects Of Spatiotemporal Resource Heterogeneity On Home Range Size Of American Beaver, L. F. Mcclintic, J. D. Taylor Ii, J. C. Jones, R. D. Singleton, G. Wang
United States Department of Agriculture Wildlife Services: Staff Publications
Home range size of terrestrial animals may be influenced by spatiotemporal dynamics of resources. However, little is known regarding the effects of spatiotemporal resource availability on semi-aquatic central place foragers such as the American beaver Castor canadensis. From January 2011 to April 2012, 26 beavers at 11 wetlands at Redstone Arsenal in north-central Alabama, USA, were captured and radio-tracked using radio telemetry. The objectives of this study were to test the predictions of three hypotheses: (1) the resource dispersion hypothesis: more spatially dispersed resources throughout a landscape increase home range sizes; (2) the temporal resource variability hypothesis: more temporally …

United States Department of Agriculture Wildlife Services: Staff Publications
Background: Cottontails (Sylvilagus spp.) are common mammals throughout much of the U.S. and are often found in peridomestic settings, potentially interacting with livestock and poultry operations. If these animals are susceptible to avian influenza virus (AIV) infections and shed the virus in sufficient quantities they may pose a risk for movement of avian influenza viruses between wildlife and domestic animals in certain situations.
Methodology/Principal Findings: To assess the viral shedding potential of AIV in cottontails, we nasally inoculated fourteen cottontails with a low pathogenic AIV (H4N6). All inoculated cottontails shed relatively large quantities of viral RNA both nasally ( …
Understory Fern Community Structure, Growth And Spore Production Responses To A Large-Scale Hurricane Experiment In A Puerto Rico Rainforest, Joanne M. Sharpe, Aaron B. Shiels
Understory Fern Community Structure, Growth And Spore Production Responses To A Large-Scale Hurricane Experiment In A Puerto Rico Rainforest, Joanne M. Sharpe, Aaron B. Shiels
United States Department of Agriculture Wildlife Services: Staff Publications
Ferns are abundant in most rainforest understories yet their responses to hurricanes have not been wellstudied. Fern community structure, growth and spore production were monitored for two years before and five years after a large-scale experiment that simulated two key components of severe hurricane disturbance: canopy openness and debris deposition. The canopy was opened by cutting branches above 3 m and the fallen leaf and woody debris was either added to or removed from the forest floor resulting in four treatments that were replicated three times in a factorial design. Of the 16 fern species observed during the experiment 12 …
The Chemical Senses In Birds, Larry Clark, Julie Hagelin, Scott J. Werner
The Chemical Senses In Birds, Larry Clark, Julie Hagelin, Scott J. Werner
United States Department of Agriculture Wildlife Services: Staff Publications
7.1 CHEMICAL SENSES
The chemical senses generally fall into three categories: chemesthesis (irritation and pain), olfaction (smell), and gustation (taste). Traditionally, the emphasis in describing responsiveness to chemical stimuli has been placed on taste and smell. The reality is more complex. For example, the sensory afferents for chemesthetic perception are in close proximity with olfactory receptors in the nasal cavity and with gustatory receptors in the oral cavity. Because external chemical stimuli can be processed by multiple sensory systems, there has been a great deal of confusion in the literature on the importance of individual sensory modalities. Generally, the principal …
Memory-Based Quantity Discrimination In Coyotes (Canis Latrans), Salif Mahamane, Kevin L. Grunig, Joseph Baker, Julie K. Young, Kerry E. Jordan
Memory-Based Quantity Discrimination In Coyotes (Canis Latrans), Salif Mahamane, Kevin L. Grunig, Joseph Baker, Julie K. Young, Kerry E. Jordan
United States Department of Agriculture Wildlife Services: Staff Publications
Previous research has shown that the ratio between competing quantities of food significantly mediates coyotes‘ (Canis latrans) ability to choose the larger of two food options. These previous findings are consistent with predictions made by Weber‘s Law and indicate that coyotes possess quantity discrimination abilities that are similar to other species. Importantly, coyotes‘ discrimination abilities are similar to domestic dogs (Canis lupus familiaris), indicating that quantitative discrimination may remain stable throughout certain species‘ evolution. However, while previously shown in two domestic dogs, it is unknown whether coyotes possess the ability to discriminate visual quantities from memory. …

The Lived Experiences Of Adult Siblings Of Individuals With Asd, Brianne Redquest
The Lived Experiences Of Adult Siblings Of Individuals With Asd, Brianne Redquest
Theses and Dissertations (Comprehensive)
Autism Spectrum Disorders (ASD) are the most prevalent neurological and severe developmental disorder affecting 1 in 88 Canadians, reflecting a 78% increase over the last 6 years (Autism Speaks Canada, 2013). ASD is a lifelong disorder which requires a tremendous amount of support and caregiving from family members. As a result, siblings may have unique experiences associated with having a sibling with ASD. As such, the purpose of this study was to examine the lived experiences of adult siblings of individuals with ASD. The study employed a qualitative methodology, more specifically phenomenology (Patton, 2002). One-on-one semi-structured interviews were conducted with …
Polish Or Work? Four Women Novelists And The Professionalization Of Accomplishment, 1796-1814, Ada Sharpe
Polish Or Work? Four Women Novelists And The Professionalization Of Accomplishment, 1796-1814, Ada Sharpe
Theses and Dissertations (Comprehensive)
Polish or Work? Four Women Novelists and the Professionalization of Accomplishment, 1796-1814 examines the ways in which cultural models of accomplished, industrious femininity find expression in four novels written by women during the Romantic period: Amelia Opie’s The Father and Daughter (1801), Mary Brunton’s Self-Control (1811), Ann Radcliffe’s The Italian (1796), and Frances Burney’s The Wanderer (1814). This dissertation reads accomplishment as a pervasive and familiar cultural practice that writers use to interrogate domestic ideology and middle-class women’s position in commercial society within the space of popular fiction. I focus, specifically, on instances in which the genteel heroine turns privately …
The Transient Collaboration Model: Theory Building, Structural Formation, And Operationalization, Adrian C. Tan
The Transient Collaboration Model: Theory Building, Structural Formation, And Operationalization, Adrian C. Tan
Theses and Dissertations (Comprehensive)
This thesis seeks to describe the Transient Collaboration Model as a business model, its underlying theoretical principles, its empirical evidence, and its types of possible collaboration structures. The research seeks to determine how companies may build sustained competitive advantages through the structural design of their collaboration associations as a strategic option. Companies' ability to retain long-term competitive advantages is limited in more unpredictable environments. Companies could not afford to internally build and hold all the possible varieties and quantities of resources and capabilities to build future competitive advantages. Collaboration can provide companies with access to multiple partners with diverse resources …
The Innate Antiviral Effects Of Extracellular Viral Dsrna In Rainbow Trout Cells, Sarah J. Poynter
The Innate Antiviral Effects Of Extracellular Viral Dsrna In Rainbow Trout Cells, Sarah J. Poynter
Theses and Dissertations (Comprehensive)
Viral double-stranded RNA (dsRNA) molecules are a potent pathogen-associated molecular pattern and play a crucial role in the innate immune response. During a viral infection, extracellular and intracellular dsRNA can initiate pathways resulting in the production of type I interferons (IFNs) and interferon-stimulated genes (ISGs). The accumulation of ISGs within a cell results in a protective antiviral state. This study used both commercially available dsRNA (poly I:C) and in vitro transcribed dsRNA molecules, based on the viral hemorrhagic septicemia virus (VHSV) genome sequence, as stimuli to investigate the effects of these molecules on the innate immune response in rainbow trout …
Endocannabinoid Involvement In Impulsivity And Decision-Making, Christopher P. Norris
Endocannabinoid Involvement In Impulsivity And Decision-Making, Christopher P. Norris
Theses and Dissertations (Comprehensive)
Problem gambling is a widespread phenomenon with a prevalence estimate of 2.3% globally (Williams, Volberg, & Stevens, 2012). Although little is known about the neurochemistry underlying this pathological behaviour, evidence suggests that dysregulation of the brain’s endocannabinoid (eCB) system may be implicated in impulsivity and decision-making. For example, chronic cannabis users exhibit impulsive behaviour and impaired decision-making on the Iowa Gambling Task (IGT). The present study sought to further examine the role of the eCB system in problem gambling-related decision-making in laboratory rats using the five-choice serial reaction time task (5-CSRTT), and a recently-developed rodent analogue of the IGT called …
Integrated Spatial Analysis Of Volunteered Geographic Information, Haydn Lawrence
Integrated Spatial Analysis Of Volunteered Geographic Information, Haydn Lawrence
Theses and Dissertations (Comprehensive)
Volunteered Geographic Information (VGI) is becoming a pervasive form of data within geographic academic research. VGI offers a relatively new form of data, one with both potential as a sensitive way to collect information about the world, and challenges associated with unknown and heterogeneous data quality. The lack of sampling control, variable expertise in data collection and handling, and limited control over data sources are significant research challenges. In this thesis, data quality of VGI is tackled as a general composite measure based on coverage of the dataset, the evenness in the density of data, and the relative evenness in …
Juror Perceptions Of Eyewitness Identification Evidence, Timothy G. Wykes
Juror Perceptions Of Eyewitness Identification Evidence, Timothy G. Wykes
Theses and Dissertations (Comprehensive)
Jurors rely on eyewitness testimony in deciding a defendant’s guilt or innocence. Archival analyses of hundreds of post-conviction DNA exonerations have identified eyewitness misidentification as the highest individual factor contributing to wrongful convictions (Innocence Project, 2014). Internationally, criminal justice systems have employed procedural safeguards (PSs) to educate juries on factors affecting eyewitness identification accuracy. Two such safeguards include the introduction of eyewitness expert testimony during trial proceedings and the reading of cautionary instructions by a presiding judge. In an independent factorial design, this research sought to examine the effects of a model judicial caution drafted by the Ontario Judicial Council …
