Lessons from Two Decades of Hanta Virus Research

Dr. Richard J. Douglass has been conducting small mammal field studies since 1968. For the past 19 years he has been conducting field studies on the ecology of deer mice and hantavirus in Montana, Panama, and Argentina. He has published papers on mammals from rodents to large ungulates. He has been conducting student field trips at Montana Tech since 1983.

Reading Our Land Use Legacy in Groundwater: Nitrate Dynamics in the Judith River Watershed

Elevated nitrate in groundwater is common is agricultural areas where fertilizer has been added at high rates for decades. Within the Judith River Wastershed, high native soil fertility allowed for dryland wheat production without N fertilization until the 1980s, yet elevated nitrate levels were frequently observed in shallow aquifers. Dr. Stephanie Ewing presents results for soil, groundwater and surface water analyses from a hydrologically isolated strath terrace near Moccasin, MT. In context of this uniquely well constrained field setting, these observed data, along with land use history and a simple mass balance model, revel the long term development and perturbation of native soil fertility with cultivation.

Great Falls Tectonic Zone: A Perspective from Idaho

An overview of geologic constraints on the age and extent of the Great Falls tectonic zone, a northeast-trending set of faults identified in west-central Montana.

High Temperature Superconductivity: Taming Serendipity

A century after the discovery of superconductivity, the design of new and more useful superconductors remains enigmatic. High-temperature super-conductors offer unique solutions to fundamental grid challenges of the 21st century and hold great promise in addressing global energy challenges in energy production, storage, and distribution. Traditionally guided by serendipity, researchers now endeavor to design new superconductors predictively. Advanced experimental techniques, such as point contact spectroscopy measurements, aid in identifying promising candidates.

The Geology of Central Chile's Long-Lived Volcanic Arc

Discussion of subduction zones that are associated with volcanic arcs and major chemical exchanges between the Earth's surface and underlying mantle.

Same Same but Different: Returning to Vietnam after 40 Years

Dan Cornell returned to Vietnam in 2012, more than 40 years after he was stationed there. From 1970-1971, Dan spent time flying around Vietnam and the neighboring countries in a large, CH-47 helicopter. There was not much time to think about what he was doing or why. In spite of this, Dan managed to become enticed bu this country so different from his own. This presentation features videos and photos from his 8-week trip.

Energy: the Next Fifty Years

Energy is basic to human society, like food, shelter, communication, and mobility. A new international energy landscape is emerging as developing countries create their energy infrastructures and as energy technologies move away from fossil toward more sustainable sources and uses. The 50-year time scale for significant change to the energy landscape implies that the strategic research and development choices we make now ill determine future energy and societal outcomes. The promising opportunities for science and technology discovery and development in energy will be analyzed in the context of vibrant, interactive and rapidly advancing national and global societies.

Geology of the Butte Ore Deposit

Dr. John Dilles discusses the geochemistry of the porphyry Cu-Mo resource found at at Butte, Montana. The porphyry formed from dilute magmatic fluids that contained 1,000s of ppm Cu between 66 and 64 Ma, and at depths of ~8 km. The porphory is zoned from innermost Cu (Ag) ore; to mixed intermediate Cu (Zn, Ag) / Zn-MJn-Ag (Cu, Pb, Au) ore; to an outer Mn-Ag (Pb) ore that grades to barren quartz.

Looking at Chemistry in Hard to See Places: Understanding Energy Conversion at 1400° Celsius

Solid oxide fuel cells (SOFCs) are promising devices for stationary and portable power and heat generation, because they can use complex fuels such as hydro-carbons, CO, and alcohols. Extreme, non-equilibrium conditions and high tem-peratures (≥ 700 ˚C) required for SOFC operation hamper efforts to understand the mechanisms of component degradation in SOFCs. This talk focuses on new insights into SOFC chemistry and the conversion of carbon-containing fuels (both hydrocarbons and oxygenated) into electricity, carbon dioxide and water, gleaned from a combination of techniques including electrochemical impedance spectroscopy, voltammetry, and vibrational Raman scattering.

Road Ecology: A Practitioner's Tale

Road Ecology is a relatively new sub-discipline of ecology that focuses on understanding the interactions between road systems and the natural environment. Wildlife crossings that allow animals to safely cross human-made barri-ers such as roads, are intended not only to reduce animal-vehicle collisions, but ideally to provide connectivity of habitat areas, combating habitat fragmentation. Wildlife mitigation strategies to improve the permeability of our infrastructure can include a combination of structures (overpasses/underpasses), at-grade crossings, fencing, animal-detection systems, and signage. One size does not fit all and solutions must be considered on a case-by-case ba-sis. Often, the feasibility of the preferred mitigation solution depends on a combination of variables including road geometrics, topography, traffic patterns, funding allocations, adjacent land use and landowner cooperation, the target wildlife species, their movement patterns, and habitat distribution. Joe and Deb will speak to the current road ecolo-gy practices in Montana and some real-world applications from the Department of Transportation.

Tracking Montana’s Groundwater: 20 Years of Lessons Learned

Long-term water-level measurements provide a fundamental indicator of the health of Montana's groundwater resources. For more than 20 years the Groundwater Assessment Program has monitored groundwater levels across the state. This lecture reviews the State's groundwater use and shows how climate variability, groundwater development, and land-use has impacted different aquifers.

Opportunities in Materials Processing: Metal Casting

Revitalizing manufacturing in the US is a hot topic, and the $1B National Network for Manufacturing Innovation (NNMI) has three new centers focused on metal casting. For structural applications, magnesium casting, structural die-cast alloys, austempered ductile and compacted graphite cast iron, and high strength steel promise dramatic weight reduction and improved performance. Recent experiments and modeling at UAB focus on the development of such new materials and processing routes. A study of the rare earth content in an aerospace magnesium alloy is presented.

Why is this Grizzly Bear in My Backyard?

This presentation provides an overview of the type of work that involves trying to resolve human/grizzly bear conflicts. Much of this work involves public education, cap-turing, handling, and monitoring grizzly bears, the use of Karelian Bear Dogs, and using new technology. Some of the new technology includes the use of remote cameras, an au-tomated bear trap, microchips, DNA, GPS radio collars, and an Electro-Optic/Infrared imagery system to locate grizzly bears.
