Flexibility in the mineral dependent metabolism of a thermoacidophilic crenarchaeote
(Montana State University - Bozeman, College of Letters & Science, 2017)This dissertation focuses on understanding the metabolic flexibility of a thermoacidophilic crenarchaeote, the mechanisms underlying its physiology, and the consequences for its ecology. Acidianus strain DS80 was isolated ... -
Stratigraphic framework and provenance of the lower belt (Newland Formation), Belt Supergroup, Helena Embayment, central Montana
(Montana State University - Bozeman, College of Letters & Science, 2017)The Belt Supergroup is exposed in western Montana where most of the unit is allochthonous due to Sevier thrusting. However, east of the Helena salient several autochthonous sections of Newland Formation pin it to central ... -
Our bodies, our lives, our right to decide? : reproductive freedom, self-directed dying, and women's autonomy
(Montana State University - Bozeman, College of Letters & Science, 2017)Statement of Problem: Autonomy is a key and evolving concept in American identity. As the bioethical concept of patient autonomy develops and the elderly population in the U.S. grows, end-of-life decisions including ... -
Zinc efficiency and diversity of Montana wheat and barley
(Montana State University - Bozeman, College of Agriculture, 2017)Zn is essential for all living organisms because of its functional, structural and regulatory roles in more than 300 enzymes found in eukaryotes (McCall, 2000). In plants and humans, trace metal deficiencies cause an altered ... -
Microbial ecology of mosquitos and ticks
(Montana State University - Bozeman, College of Letters & Science, 2017)Host evolutionary history has been shown to select for distinct host associated microbial communities over large evolutionary time scales. The microbiomes of disease vector have been shown to alter the capacity of their ... -
Validating Salmonella typhimurium virulence modulation by ecto-5'-nucleotidase (CD73) in intestinal epithelial cells
(Montana State University - Bozeman, College of Letters & Science, 2017)Extracellular ATP is a pro-inflammatory molecule released during intestinal insult and must be converted to adenosine by ecto-5'-nucleotidase (CD73) for the resolution of intestinal inflammation [1]. Along with its ... -
Land-atmosphere exchange of carbon and energy at a tropical peat swamp forest in Sarawak, Malaysia
(Montana State University - Bozeman, College of Agriculture, 2017)Tropical peatlands comprise 11% of the global peat area of ca. 400 Mha and are estimated to store about 89 Gt of carbon (C). However, considerable uncertainties remain about their present role in global C cycle as interannual ... -
Theoretical analysis and experimental design of dual-beam optical trap for large particles
(Montana State University - Bozeman, College of Letters & Science, 2018)Ultra-high sensitivity acceleration and gryometric sensors have been proposed as optically levitated particles in ultra-high vacuum (UHV). Larger particles (10- 30 microns in diameter) provide higher sensitivity, but they ... -
Validation of high strain rate, multiaxial loads using an in-plane loader, digital image correlation, and FEA
(Montana State University - Bozeman, College of Engineering, 2018)Montana State University's In-Plane Loader (IPL) is a machine designed to test for mechanical properties at multi-axial states of stress and strain by in-plane translation and rotation. Historically the machine has been ... -
Reactive evaporation of chromium from stainless steel and the reactive condensation of chromium vapor species on ceramic surfaces
(Montana State University - Bozeman, College of Engineering, 2018)Stainless steels are often used in high temperature (greater than or equal to 500°C) applications such as solid oxide fuel cells (SOFCs), combustion engine exhaust systems, and various power/chemical plant process equipment. ... -
Nuclear magnetic resonance studies to characterize phase transitions in porous systems
(Montana State University - Bozeman, College of Engineering, 2018)Nuclear magnetic resonance (NMR) allows for in-situ non-invasive studies of a wide range of systems at microscopic time and length scales. NMR relaxometry and diffusometry techniques along with magnetic resonance imaging ... -
The emergence of collective behavior on social and biological networks
(Montana State University - Bozeman, College of Letters & Science, 2018)In this thesis, we broadly examine collective behaviors in various social and biological contexts. Aggregation, for instance, is a natural phenomenon that occurs in a variety of contexts; it is observed in schools of fish, ... -
Post-prandial serum concentrations of Trimethylamine-N-oxide in overweight and obese adults with low and high systemic inflammation
(Montana State University - Bozeman, College of Education, Health & Human Development, 2018)Purpose: Elevated trimethylamine-N-oxide (TMAO) levels have been implicated in the development of atherosclerosis. The impact of a high-fat meal on the post-prandial TMAO response in healthy overweight and obese adults was ... -
Rural nurse residency: promoting the nurse graduate transition to frontier critical access hospital
(Montana State University - Bozeman, College of Nursing, 2018)Purpose/Aim: The purpose of this pilot project was to test the feasibility of a rural nurse residency program to support the new graduate nurse in their transition to the role of a professional rural nurse, resulting in ... -
The effect of air pollution on exam performance: a case study using California public high schools
(Montana State University - Bozeman, College of Agriculture, 2018)The California High School Exit Exam (CAHSEE) and natural variation in ambient air quality are used to estimate the effect of pollution exposure on exam performance. Two regularly monitored air pollutants, particulate ... -
Combining acoustic emission and guided ultrasonic waves for global property prediction and structural health monitoring of glass fiber composites
(Montana State University - Bozeman, College of Engineering, 2018)Since the turn of the century, wind turbines have been rapidly growing in size and are projected to continue growing as the technology develops. These increases in size have led to increased failure rates of the glass fiber ... -
Nontraditional student's transition to college through the lens of Bronfenbrenner's ecological theory, Schlossberg's transition theory and gender schema theory
(Montana State University - Bozeman, College of Education, Health & Human Development, 2018)Over the past several decades, an increasing number of nontraditional students have been enrolling in college, however they face a variety of challenges in completing their educational goals and have lower completion rates ... -
The value of telemedicine in rural healthcare and associated financial obligation
(Montana State University - Bozeman, College of Nursing, 2018)The purpose of this project was to raise awareness of the vital impact emergency room telemedicine has on rural residents and health care and the financial challenges facilities face to maintain these services following ... -
Does increased task difficulty reveal individual differences in executive function in the domestic dog?
(Montana State University - Bozeman, College of Letters & Science, 2018)Pet dogs are carnivores that inhabit a largely human-dominated context, in which certain normal canid behaviors (e.g., resource-guarding, barking, mounting) are considered undesirable and even dangerous. Safety and welfare ... -
A study on dynamic bicycle detection and warning device
