Technology And The Printed Book: Pursuing A Holistic Human Experience With A Sacred Text, Rachel Dugan

Masters Theses

There exists a sort of gravitas attached to a book that is printed and bound by hand that gets lost on the production line. When holding a hand-printed (or hand-written), hand-bound codex next to a mass-produced book, there is between the two a visible and tactile difference in quality and harmony between form and content. With the modern technological advancements now available, how can the craftsmanship and beauty — the gravitas — evident in books of the past be replicated in a way that is aesthetically pleasing, harmonious in message, and reflective of the present time? As objects, books are …

Some Features Of Participant Reference In Xochapa Mixtec, Laura J. Cline

Theses and Dissertations

Many works have been published about the grammar and phonology of Mixtecan languages, but relatively little has been written about the discourse features of these languages. One of these areas of discourse where relatively little research has been done is that of participant reference.

This thesis explores the features of participant reference in one Mixtec language, Xochapa Mixtec, by examining the use of nouns, pronouns, and deictic phrases in eight Xochapa Mixtec texts. The texts used in this research were transcribed from audio recordings and then analyzed with respect to the participant reference forms they employed. The thesis begins with …

Mechanisms Of S1p-Induced Endothelial Barrier Enhancement, Natascha Guimarães Alves

USF Tampa Graduate Theses and Dissertations

Excessive microvascular permeability is a serious complication involved in traumatic injury and inflammatory diseases. Alcohol intoxication can exacerbate the physiological derangements produced by microvascular endothelial barrier dysfunction in such disease conditions. Sphingosine-1-phosphate (S1P) has known endothelial barrier-protective properties, and has been shown to ameliorate microvascular leakage in a model of combined alcohol intoxication and hemorrhagic shock and resuscitation (HSR). However, whether the barrier-protective properties of S1P extend to endothelial cells of the blood-brain barrier (BBB) is unclear. The mechanisms of S1P-induced barrier protection during alcohol intoxication or HSR are also unknown. In the current study, we tested the hypothesis that …

Investigating Autophagy Dysfunction Induced By A Parkinson's Disease-Causing Mutation In Vps35, Abir Ashfakur Rahman

Boise State University Theses and Dissertations

Parkinson’s Disease (PD) is an idiopathic disorder with no known cure. With number of cases steadily rising around the world, it is imperative to turn to the underlying cellular and molecular mechanisms of the disease manifestation and neurodegeneration to craft novel modes of therapy. VPS35 is one of the few genes that have identified and definitively linked to familial PD. The particular mutation that has been associated is known to cause dysfunction of a key cellular process known as autophagy. This process is primarily responsible for clearance of unwanted, damaged or misfolded proteins, among other things. Our study reveals an …

Local Peer-To-Peer Communication To Improve Demand Response In Residential Neighborhoods, Ryan Schwartz

Boise State University Theses and Dissertations

Increased electricity production from intermittent renewables presents a challenge to utilities. Since the grid has little ability to store energy, fluctuations in solar and wind generation require either an increase in generation from expensive sources or a reduction of demand. Demand Response (DR) programs focus on the latter and are designed to increase grid flexibility by allowing grid operators to modify when or how customers use electricity. For residential customers, this typically means shedding load during periods of high demand through a central controller temporarily shutting off air conditioning (AC) compressors. This type of DR can cause spikes in demand …

The Effect Of Supplementary Ultraviolet Wavelengths On Broiler Chicken Welfare Indicators, Charlotte James, Lucy Asher, Katherine Herborn, Julian Wiseman

School of Biological and Marine Sciences

© 2018 The Authors Qualities of the light environment are important for good welfare in a number of species. In chickens, UVA light is visible and may facilitate flock interactions. UVB wavelengths promote endogenous vitamin D synthesis, which could support the rapid skeletal development of broiler chickens. The aim of the study was to investigate the impacts of Ultraviolet wavelengths (UV) on welfare indicators in broiler chickens. Day-old Ross 308 birds reared under commercially representative conditions were randomly assigned to one of three lighting treatments: A) White Light Emitting Diode (LED) and supplementary UVA LED lighting (18-hour photoperiod); B) White …

Herbivorous Turtle Ants Obtain Essential Nutrients From A Conserved Nitrogen-Recycling Gut Microbiome, Yi Hu, Jon G. Sanders, Piotr Łukasik, Catherine L. D'Amelio, Mark P. Schotanus

University Faculty Publications and Creative Works

Nitrogen acquisition is a major challenge for herbivorous animals, and the repeated origins of herbivory across the ants have raised expectations that nutritional symbionts have shaped their diversification. Direct evidence for N provisioning by internally housed symbionts is rare in animals; among the ants, it has been documented for just one lineage. In this study we dissect functional contributions by bacteria from a conserved, multi-partite gut symbiosis in herbivorous Cephalotes ants through in vivo experiments, metagenomics, and in vitro assays. Gut bacteria recycle urea, and likely uric acid, using recycled N to synthesize essential amino acids that are acquired by …

Optimization Of The Practice Of Slow Cooling Steel Bars: A Redesign And Modernization Of Materials, Eryn Johnston

Mechanical Engineering Undergraduate Honors Theses

Throughout the process of steel making, certain grades of steel are a higher risk for defects caused by the inability to quickly diffuse hydrogen through the steel when cooled to room temperature at a normal rate based on the ambient air temperature. To reduce the hydrogen flaking defects that are caused due to hydrogen entrapment in the steel, the process of slow cooling is utilized. This process reduces the cooling rate of steel bars by keeping them at a higher temperature for extended periods and in turn gives the hydrogen a chance to fully dissipate from the steel. In many …

Diversification Across A Dynamic Landscape: Phylogeography And Riverscape Genetics Of Speckled Dace (Rhinichthys Osculus) In Western North America, Steven Michael Mussmann

Graduate Theses and Dissertations

Evolution occurs at various spatial and temporal scales. For example, speciation may occur in historic time, whereas localized adaptation is more contemporary. Each is required to identify and manage biodiversity. However, the relative abundance of Speckled Dace (Rhinichthys osculus), a small cyprinid fish in western North America (WNA) and the study species for this dissertation, establishes it an atypical conservation target, particularly when contrasted with the profusion of narrowly endemic forms it displays. Yet, the juxtaposition of ubiquity versus endemism provides an ideal model against which to test hypotheses regarding the geomorphic evolution of WNA. More specifically, it also allows …

Study Of Three Potential Variables That May Impact The Maximum Shear Force And Shear Variation During The Growth And Transport Of Mixed Sex Broilers Grown In Commercial Poultry Houses, Mark Christie

Graduate Theses and Dissertations

Temperature conditions during the transportation to the processing facility of commercial broilers have a direct impact on the meat texture, specifically maximum shear force and shear variation of cooked breast meat. Analysis of a calendar year of flock data (N=346), reveals that the largest impact of transport conditions, specifically temperature, is on the standard deviation of the flocks range of cooked shear values. The optimal transport temperature that yields broiler breast meat with average flock minimum shear and standard deviation values is approximately 60°F. The shear values for flocks at or near 60°F are on average 1 kg less than …

Evolutionary Dynamics Of Brown Treesnake (Boiga Irregularis) Reproductive Ecology, With Implications For Invasive Species Control, Brenna Aaren Levine

Graduate Theses and Dissertations

Invasive species represent major threats to biodiversity, global economies, and human health. Consequently, extensive research has been directed towards improving methods that restrict and contain them. Yet, control measures can also act as agents of selection by significantly impacting the reproductive capacity of invasives (in the context of “eco-evo” dynamics). The end result is that control measures subsequently alter the fitness landscape of an invasive over ecologically-relevant time, and lose their efficacy by so doing. However, adaptive management can be promoted by investigating the relationships between reproductive ecology, strength of selection, and (additive) genetic variation. In short, effective control can …

Periodicals In Transition: Politics And Style In Victorian Higher Journalism, David Blaine Walker

Graduate Theses and Dissertations

Covering a period roughly from the mid-1820s through the early-1880s, this dissertation investigates transformations in the style and substance of political discourse practiced in British organs of “higher journalism.” Animating certain key moments and figures along the way, it explains the shift from a periodical market dominated by the anonymous, lengthy treatises found in quarterly reviews like the Edinburgh Review (f. 1802) and its rivals, to an industry dominated by monthly reviews that generally eschewed both the anonymity of its contributors as well as the prohibitive length of its predecessors. In exploring this transition from the “Age of the Quarterlies” …

Impedance Sensing Of Cancer Cells Directly On Sensory Bioscaffolds Of Bioceramics Nanofibers, Hanan Alismail

Graduate Theses and Dissertations

Cancer cell research has been growing for decades. In the field of cancer pathology, there is an increasing and long-unmet need to develop a new technology for low-cost, rapid, sensitive, selective, label-free (i.e. direct), simple and reliable screening, diagnosis, and monitoring of live cancer and normal cells in same shape and size from the same anatomic region. For the first time on using an impedance signal, the breast cancer and normal cells have been thus screened, diagnosed and monitored on a smart bioscaffold of entangled nanowires of bioceramics titanate grown directly on the surface of implantable Ti-metal and characterized by …

Quantitative Microbial Risk Assessment For Parts, Ground, And Msc Poultry Product Including Intervention Analysis And Exploration Of Enterobacteriaceae As An Indicator Organism In Poultry Processing, Leigh Ann Parette

Graduate Theses and Dissertations

Samples collected at five different large bird poultry processing facilities over a period of 7 months from prescald to post debone locations were enumerated for Enterobacteriaceae, Salmonella spp., and Campylobacter spp. and the results were used to create Quantitative Microbial Risk Analyses (QMRA) models for parts, ground, and mechanically separated chicken (MSC) products. Sensitivity analyses indicated the points in the process at which reductions would be most advantageous to the endpoint and simulation models were run to test reductions required to meet the current USDA performance standards.

These data were analyzed to determine the reductions from one node (location) to …

Ca2+ - Induced Structural Change Of Multi-Domain Collagen Binding Segments Of Collagenases Colg And Colh From Hathewaya Histolytica, Christopher Eric Ruth

Graduate Theses and Dissertations

Hathewaya histolytica, previously renamed as Clostridium histolyticum, secretes at least two collagenases, ColH and ColG, that allow for degradation of extracellular matrices of animal tissue. Hathewaya histolytica virulence factors are proposed to undergo domain rearrangement upon secretion from the bacteria to the host. In order to accomplish this, collagenases seek the least ordered regions in collagen to efficiently disassemble the fibril. Two types of domains, Polycystic Kidney Disease-like (PKD) and Collagen Binding Domain (CBD), direct the collagenases ability to disassemble the fibril. Calcium dependent structural change have been reported to increase in thermal stability and in tighter collagen binding for …

Impact Of Roadside Maintenance Practices On Larinus Minutus (Gyllenhal), A Biological Control Agent Of Spotted Knapweed, Mary Elizabeth Ferguson

Graduate Theses and Dissertations

Spotted knapweed, Centaurea stoebe, is an invasive weed found throughout much of the United States. Spotted knapweed is a rangeland weed where it was originally introduced into western North America in the 1880s.Where spotted knapweed spread to the southeastern U.S., it is found mostly along roadsides. It has been the focus of a biological control program beginning in the 1960s, with 12 insects established, with the final introductions occurring in the 1990s. After the success observed in the western U.S. and Canada with one of these insects, Larinus minutus, this weevil was established in northwestern Arkansas. It is too early …

Graduate Theses and Dissertations

Advances in imaging technology have led to a variety of available clinical and investigational systems. In this collection of studies, we tested the relevance of morphological image feature quantification on several imaging systems and epithelial tissues. Quantification carries the benefit of creating numerical baselines and thresholds of healthy and abnormal tissues, to potentially aid clinicians in determining a diagnosis, as well as providing researchers with standardized, unbiased results for future dissemination and comparison.

Morphological image features in proflavine stained oral cells were compared qualitatively to traditional Giemsa stained cells, and then we quantified the nuclear to cytoplasm ratio. We determined …

Importance Of Forests Outside Protected Area Networks For Large-Seeded Tree Species And Their Large-Bodied Avian Frugivores--A Study In Vazhachal Reserve Forest, India, Aditi Achyut Lele

Graduate Theses and Dissertations

Western Ghats, the mountain chain running along the west coast of India, is one of eight global hotspots of biodiversity and is particularly notable for its endemic flora and fauna. Yet only 10% of this land enjoys the protected status. Vast forested lands exist outside the protected network of national parks and wildlife sanctuaries in the form of reserve forests, community forests, and private lands. The present study sought to understand the role of such forests in the context of ecological system involving large-seeded tree species that depend on large-bodied avian frugivores for seed dispersal. I conducted a study over …

Toxicity Of Formulated Insecticide Mixtures To Apis And Non-Apis Bees, Joseph Edward Belsky

Graduate Theses and Dissertations

This work investigates ecotoxicology of new insecticide mixtures to Apis and non-Apis bees. Previous studies have demonstrated the acute and sub-lethal toxicity of individual active ingredient insecticides to honey bees and to a lesser extent non-Apis bees. However, the contact toxicity of formulated premix insecticides containing multiple active ingredients to bees has not been thoroughly assessed. To address this void, laboratory studies simulating exposure to four premix insecticides under different field-realistic scenarios were conducted for two bee species.

Honey bee, Apis mellifera (Linnaeus) contact exposure was examined by simulating three scenarios: (1) when bees continuously forage in a field and …

Experimentation And Modeling Of The Effects Of Along-Wind Dispersion On Cloud Characteristics Of Finite-Duration Contaminant Releases In The Atmosphere, Jessica M. Morris

Graduate Theses and Dissertations

Along-wind dispersion, or stretching of the cloud in the direction of the wind, plays an important role in the concentration and modeling of contaminant releases in the atmosphere. Theoretical and empirical derivations were compared for appropriate parameterization of along-wind dispersion. Available field data were analyzed to evaluate and improve previous parameterizations of the along-wind dispersion coefficient, σ_x. An experimental test program was developed and executed in an ultra-low speed wind tunnel at the Chemical Hazards Research Center to determine the effects of the time distribution coefficient on true finite-duration releases from an original area source. Multiple wind speeds, release durations, …

Assessment Of Salmonella Enterica Biofilms And Expression Differences Among Serovars, Zhaohao Shi

Graduate Theses and Dissertations

Biofilms are communities of microorganisms associated by a matrix of extracellular polymers. In this state, microorganisms occupy an ecological niche distinct from their free-floating, planktonic counterparts. Also, biofilm bacteria become biologically unique as they form communities and lose motility. The acquisition of these physiological attributes enables the biofilm to persist through harsh environmental conditions, including antimicrobial induced stress and to resist sanitization efforts. Because of these features, biofilms can rapidly disseminate across numerous surfaces and as they establish, become challenging to remove. This is a particular issue for the food industry as processing plants offer favorable conditions for biofilm formation …

Genetic And Genomic Analyses Of Bacterial Responses To Different Stress Environments, Sakshi Rampal

Graduate Theses and Dissertations

Bacteria encounter a plethora of environmental stresses and have evolved different mechanisms to recognize and respond to various harmful conditions. Understanding and elucidating common themes as well as unique aspects of the molecular mechanisms underlying stress adaptation is important and can provide valuable strategies for applications. This study focuses on stress responses in three different bacteria, namely, Acidothermus cellulolyticus, Mycobacterium smegmatis and Escherichia coli. The thermophilic and acidophilic organism A. cellulolyticus was used as a model system to understand the effects of lignin phenolic acids on cellulolytic bacteria. Lignin phenolic acids pose a significant challenge to microbial deconstruction of lignocellulosic …

Lipid Extraction From Spirulina Sp. And Schizochytrium Sp. Using Supercritical Co2 With Methanol, Shihong Liu, Husam A. Abu Hajar, Guy Riefler, Ben J. Stuart

Civil & Environmental Engineering Faculty Publications

Microalgae are one of the most promising feedstocks for biodiesel production due to their high lipid content and easy farming. However, the extraction of lipids from microalgae is energy intensive and costly and involves the use of toxic organic solvents. Compared with organic solvent extraction, supercritical CO₂ (SCCO₂) has demonstrated advantages through lower toxicity and no solvent-liquid separation. Due to the nonpolar nature of SCCO_2, polar organic solvents such as methanol may need to be added as a modifier in order to increase the extraction ability of SCCO₂. In this paper, pilot scale lipid …
