A 60- Year Record Of The Demotechnic Index Of States, 1960-2019, Gavin James Kellough
A 60- Year Record Of The Demotechnic Index Of States, 1960-2019, Gavin James Kellough
Graduate Theses and Dissertations
A country’s dependency on energy resources can be interpreted through the calculation of energy indices. The Demotechnic Index (DI) was used to determine the trajectory of energy efficiency of each state in the United States over the period 1960-2019. The DI serves as a measure of the energy intensity of states and a proxy for energy sustainability of each state.The DI is the ratio of total energy use to total metabolic energy demand of a population. Mathematically, DI = (E_T-E_M)/E_M E_T represents the total energy used (metabolic energy + technological energy in kilojoules annually, kJ/y), while EM represents the basic …
Diversity – Independent Factors Predict Elevated Extinction Rates, Dustin Perriguey
Diversity – Independent Factors Predict Elevated Extinction Rates, Dustin Perriguey
Earth and Planetary Sciences Faculty and Staff Publications
Multiple linear regression was used to determine the relationships between diversity-independent factors (i.e., abiotic, climatic) 2, 5, and 10 Myrs-prior to the most elevated Phanerozoic extinctions. We constructed five abiotic variables from Phanerozoic proxy records1–5 to compare to extinction rates: mean temperature, temperature instability, carbon cycle instability, continental weathering rates, and habitat instability. All three models were statistically significant (P < 0.05) and explained > 70% of the variation in Alroy’s6 three-timer generic extinction rates. However, the 2 Myr-prior model explained the most variance in extinction rates and had the most predictive power, based on adjusted and predictive R2 (~ 72% and 41%, respectively). Carbon …

Answers In The East: An Examination Of China's Renewable Energy And Its Application To Central Appalachia, Lillian Hamm
Answers In The East: An Examination Of China's Renewable Energy And Its Application To Central Appalachia, Lillian Hamm
Mahurin Honors College Capstone Experience/Thesis Projects
While much of China’s electrification has depended on coal, recent decades illustrate the country is heavily investing in and implementing renewable energy as a power source. Even China’s coal-rich provinces, like the northeastern province of Shanxi, have been making the transition to renewable energy. The central Appalachian states comprised of eastern Kentucky, West Virginia, western Virginia, and northeastern Tennessee share many characteristics with China’s Shanxi province including economic resources, climate, and geography. Yet, central Appalachia has not been able to easily transition to renewable energy. However, there are various cultural, political, and technological differences between the two regions to explain …
Impacts Of Environmental Conditions On Fleas In Black-Tailed Prairie Dog Burrows, Julia E. Poje, Tonie Rocke, Michael D. Samuel
Impacts Of Environmental Conditions On Fleas In Black-Tailed Prairie Dog Burrows, Julia E. Poje, Tonie Rocke, Michael D. Samuel
United States Geological Survey: Staff Publications
Sylvatic plague, caused by the bacterium Yersinia pestis and transmitted by fleas, occurs in prairie dogs of the western United States. Outbreaks can devastate prairie dog communities, often causing nearly 100% mortality. Three competent flea vectors, prairie dog specialists Oropsylla hirsuta and O. tuberculata, and generalist Pulex simulans, are found on prairie dogs and in their burrows. Fleas are affected by climate, which varies across the range of black-tailed prairie dogs (Cynomys ludovicianus), but these effects may be ameliorated somewhat due to the burrowing habits of prairie dogs. Our goal was to assess how temperature and precipitation …

The Future Environmental And Health Impacts Of Coal, Robert B. Finkelman, Amy L. Wolfe, Michael S. Hendryx
Faculty, Staff, and Affiliated Publications--KGS
In the United States, coal consumption in the last 12 years has declined from 1,045,140 million short tons in 2007 to 539,420 million short tons in 2019, a decrease of almost 50%. During that period the number of electric power coal generators has declined from 1,470 to 738 accounting for 21% of capacity. An even more dramatic decrease in coal use has occurred in Western Europe. This significant reduction in coal use and the concomitant closure of coal mines and coal-burning power plants will result in substantially cleaner air, reductions in respiratory problems such as asthma, less heart disease, fewer …

Middle Miocene Paleoenvironmental Reconstruction Of The Central Great Plains From Stable Carbon Isotopes In Large Mammals, Willow H. Nguy
Middle Miocene Paleoenvironmental Reconstruction Of The Central Great Plains From Stable Carbon Isotopes In Large Mammals, Willow H. Nguy
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Middle Miocene (18-12 Mya) mammalian faunas of the North American Great Plains contained a much higher diversity of apparent browsers than any modern biome. This has been attributed to greater primary productivity, which may have supported greater browser diversity that commonly corresponds with densely vegetated habitats. However, several lines of proxy evidence suggest that open woodlands or savannas dominated middle Miocene biomes; neither of which support many browsers today. Stable carbon isotopes in mammalian herbivore tooth enamel were used to reconstruct vegetation structure of middle Miocene biomes.
Stable carbon isotopes in C3 dominated environments reflect vegetation density and herbivores …

Public Land & Resources Law Review
Holding that the widespread effects of environmental regulation on the coal industry constituted sufficient importance, the Northern District of West Virginia ordered the Environmental Protection Agency to conduct analysis on employment loss and plant reduction resulting from regulatory effects. In admonishing the EPA’s inaction, the court ruled that the Agency had a non-discretionary duty to evaluate employment and plant reduction. Furthermore, the court held that the EPA’s attempt to put forth general reports in place of required evaluations was an invalid attempt to circumvent its statutory duty.
Paleoenvironmental Analysis Of Cretaceous Mudstones At Slope Mountain, Alaska Using Carbon Stable Isotopes, Ashley Ratigan
Paleoenvironmental Analysis Of Cretaceous Mudstones At Slope Mountain, Alaska Using Carbon Stable Isotopes, Ashley Ratigan
Honors Papers
This project uses field samples, microfacies analysis, and carbon stable isotopes of mudstones to determine past environmental conditions of North Slope, Alaska during the Albian-Cenomanian (Cretaceous). Samples were taken at Slope Mountain, Alaska located north of the Brooks Range. Slope Mountain includes the Torok Formation and the upper and lower Nanushuk Formations that consist of alluvial, deltaic, and shallow marine facies that were deposited into the North Slope foreland basin on the Arctic Alaska micro plate. An exhaustive search for identifiable microfossils, such as pollen, diatoms, and foraminifera in the samples yielded nothing but charcoal and carbon residue. No other …

Tailings Tale: Mike Horse Looms Dark Over The Blackfoot, Elizabeth L. Harrison
Graduate Student Portfolios, Professional Papers, and Capstone Projects
In the spring of 1975, a heavy rain blew out an earthen dam holding back toxic metal waste from the now defunct Mike Horse mine at the headwaters of the scenic Big Blackfoot River. Federal agencies, a corporate mining giant, and the small town community of Lincoln, Montana, grapple with the repercussions and future of the watershed.

Water Quality In The Kentucky River Basin, Daniel I. Carey
Water Quality In The Kentucky River Basin, Daniel I. Carey
Information Circular--KGS
Data gathered up to 1990 suggest that water pollution problems existed throughout the Kentucky River Basin. Fecal coliform bacteria in streams was a widespread problem because of the inadequate treatment of municipal wastes, failing septic systems, and agricultural runoff. Iron, lead, manganese, mercury, and silver exceeded State standards and Federal guidelines for drinking water and aquatic life at most of the sample sites for a majority of samples. Aquatic life in many smaller streams in the Knobs region was reduced by chloride discharges from oil and gas operations, according to the Kentucky Division of Water. Organic enrichment and high nutrient …
Petrology Of The Upper Nounan - Worm Creek Sequence, Upper Cambrian Nounan And St. Charles Formations, Southeast Idaho, Lillian Donley Wakeley
Petrology Of The Upper Nounan - Worm Creek Sequence, Upper Cambrian Nounan And St. Charles Formations, Southeast Idaho, Lillian Donley Wakeley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The upper member of the Nounan Formation and the Worm Creek Member of the St. Charles Formation, both late Cambrian in age, were studied in the Bear River Range and the Fish Creek Range in southeast Idaho. Lithology and sedimentary structures of these units were compared with characteristics of similar modern sediments and ancient rocks, to determine the environments of deposition and effects of diagenesis for the interval studied.
On the basis of widely traced marker horizons, the two-member interval is divided into three parts, with parts 1 and 2 comprising the upper member of the Nounan Formation, and part …
