Carbon Fluxes In Karst Aquifers: Sources, Sinks, And The Effect Of Storm Flow, William B. White Dec 2013

Carbon Fluxes In Karst Aquifers: Sources, Sinks, And The Effect Of Storm Flow, William B. White

KIP Articles

An effective carbon loading can be calculated from measured alkalinity and pH of karst waters. The carbon loading is independent of the degree of saturation of the water and does not depend on the water being in equilibrium with the carbonate wall rock. A substantial data base of spring water analyses accumulated by students over the past 40 years has been used to probe the CO2 generation, transport, and storage in a variety of drainage basins that feed karst springs. Carbon loading in the water exiting karst drainage basins depends on the rate of CO2 generation in the soils of …


Role Of Nitrogen Defects In Nitrogen-Doped Carbon For Catalyst Support And Electric Double-Layer Capacitor, Sujan Shrestha Dec 2013

Role Of Nitrogen Defects In Nitrogen-Doped Carbon For Catalyst Support And Electric Double-Layer Capacitor, Sujan Shrestha

Doctoral Dissertations

Electrochemical applications of carbon are wide and varied. They are used as electrodes for batteries, capacitors and proton exchange membrane fuel cells (PEMFCs). This is possible due to their excellent electrical conductivity, variable nanostructure and cost-effectiveness. Besides these properties, physicochemical properties such as microstructure and surface chemistry play a significant role in the performance of carbon as electrodes in these applications. In supercapacitors or ultracapacitors, surface oxygen functionalities can increase capacitance due to non-faradaic reactions between redox couples such as quinine and hydroquinone while in PEMFCs, surface functionalities can determine catalyst size distribution and dispersion. However, surface oxygen functionalities also …

Comparison Of Odonata Populations In Natural And Constructed Emergent Wetlands In The Bluegrass Region Of Kentucky, Brittany Ann Brookshire Miss

Honors Theses

With the degradation and destruction of many natural wetlands in Kentucky, there are high incentives to look at the remaining natural wetlands and the new artificial wetlands that are beginning to become prevalent among biologists. Wetlands are important to dragonfly populations just as dragonflies are vital to wetland function. In my study I looked at the fluctuation in Odonata (dragonfly and damselfly) populations at ten artificial wetlands and ten natural wetlands in the Inner Bluegrass region of Kentucky. In my study the dragonfly populations were monitored based on Shannon and Simpson's diversity, Species richness, and number of individual and species …


Thermal, Economic And Environmental Analysis Of Domestic Solar Water Heaters In Malaysia / Fayaz Hussain, Fayaz Hussain Dec 2013

Thermal, Economic And Environmental Analysis Of Domestic Solar Water Heaters In Malaysia / Fayaz Hussain, Fayaz Hussain

Student Works (2010-2019)

Solar thermal utilization, especially the application of solar water heater technology, has developed rapidly in recent decades. Solar water heating systems are practical applications to replace the use of electrical water heaters. But the performance of these systems depends on weather and exhibit a nonlinear dependence. This makes it difficult to accurately analyze their performance by simply observing their response to short-term or average weather conditions. The purpose of this project is to show solar potential through contour mapping and do thermal, economic and environmental analysis of evacuated-tube, glazed and unglazed collector solar water heaters. The optimum performance of solar …

Evolution Of The Superconductivity Dome In The Two-Dimensional Hubbard Model, K. S. Chen, Z. Y. Meng, S. X. Yang, T. Pruschke, J. Moreno, M. Jarrell

Faculty Publications

In a recent publication, we identified a line of Lifshitz transition points separating the Fermi liquid and pseudogap regions in the hole-doped two-dimensional Hubbard model. Here, we extend the study to further determine the superconducting transition temperature in the phase diagram. By means of large-scale dynamical cluster quantum Monte Carlo simulations, we are able to identify the evolution of the d-wave superconducting dome in the hole-dope side of the phase diagram, with next-nearest-neighbor hopping (t′), chemical potential, and temperature as control parameters. To obtain the superconducting transition temperature Tc, we employ two-particle measurements of the pairing susceptibilities. As t′ goes …

Intercalibration Of Quikscat And Oscat Land Backscatter, John Colin Barrus Dec 2013

Intercalibration Of Quikscat And Oscat Land Backscatter, John Colin Barrus

Theses and Dissertations

The Ku-band SeaWinds-on-QuikSCAT scatterometer (QuikSCAT) operated continuously from 1999 to 2009. Though its primary mission was to estimate global ocean winds, QuikSCAT has proven useful in a variety of geophysical studies using land backscatter measurements. The end of the primary QuikSCAT mission in 2009 has prompted interest for continuing the QuikSCAT land dataset with other scatterometers. The Oceansat-2 scatterometer (OSCAT), launched in 2009, is a viable candidate for continuing the QuikSCAT time series because of the similarities of both sensors in function and design. An important difference in the sensors is that they operate at slightly different incidence angles. Continuing …

Understory Vegetation Response To Mechanical Mastication Of Piñon And Juniper Woodlands, Jordan Ann Bybee

Theses and Dissertations

Piñon and juniper encroachment and infilling can alter ecosystem processes and decrease resilience and resistance in sagebrush grasslands. Land managers employ a variety of techniques to eliminate these trees and mitigate their negative effects. Mechanical mastication or shredding is an increasingly popular method of removing these trees in Utah. It is a versatile treatment that can reduce canopy fuels, increase infiltration, and reduced sediment loss. We compared vegetation cover for annual and perennial vegetation functional groups on shredded and adjacent unshredded areas across a range of sites. Our approach was to categorize sites by ecological site type (encroachment or tree) …

Capillary Channel Flow Experiments Aboard The International Space Station, Michael Conrath, P. J. Canfield, P. M. Bronowicki, Michael E. Dreyer, Mark M. Weislogel, A. Grah

Mechanical and Materials Engineering Faculty Publications and Presentations

In the near-weightless environment of orbiting spacecraft capillary forces dominate interfacial flow phenomena over unearthly large length scales. In current experiments aboard the International Space Station, partially open channels are being investigated to determine critical flow rate-limiting conditions above which the free surface collapses ingesting bubbles. Without the natural passive phase separating qualities of buoyancy, such ingested bubbles can in turn wreak havoc on the fluid transport systems of spacecraft. The flow channels under investigation represent geometric families of conduits with applications to liquid propellant acquisition, thermal fluids circulation, and water processing for life support. Present and near future experiments …

A result found was the performance of the classifier can be optimized by reducing the number of macroeconomic features needed by 30% using Sequential Feature Selection. Further performance enhancement was achieved by optimizing the RBF kernel and SVM parameters …


Rf Transport Electromagnetic Properties Of Graphene From Dc To 110 Mhz, Sa Awan, G Pan, Taan Lm Al, B Li Dec 2013

Rf Transport Electromagnetic Properties Of Graphene From Dc To 110 Mhz, Sa Awan, G Pan, Taan Lm Al, B Li

School of Engineering, Computing and Mathematics

The paper describes measurement of RF transport electromagnetic properties of CVD graphene over the DC to 110 MHz frequency range at room temperature. Graphene on Si/SiO2 substrate was mounted in a shielded four terminal-pair (4TP) adaptor which enabled direct connection to a calibrated precision impedance analyser for measurements. Good agreement is observed for the DC four-probe resistance and the 4TP resistance at 40 Hz, both yielding R ~104 Ohms. In general the apparent graphene channel electromagnetic properties are found to be strongly influenced by quantum contact effects, such as resistance and capacitance, particularly at DC and low frequencies f < 1 MHz. A phenomenological lumped-parameter equivalent circuit model is presented which matches the frequency response of the graphene 4TP impedance device over approximately seven decades of the frequency range of the applied transport alternating current. Based on this model, the intrinsic graphene channel resistance is found to be RG = 2.2 Ohms or sheet resistance of 3.85 Ohms/sq, which is frequency independent, with each contact impedance being RC = 51.6 Ohms and CC = 1.2 nF. These results suggest that our RF 4TP method may be more accurate and reliable than the conventional DC four-probe method for measuring the intrinsic sheet resistance of single-atom thick materials such as graphene. This may be significant for the production and optimisation of graphene for solar-cells and touch-screen displays where sheet resistance (combined with its optical transparency) figures-of-merit play an important role, particularly in comparison with the values of the current material of choice, indium tin oxide (ITO), for such applications.

Assumptions About Consumption In The Archaeology Of Late Nineteenth-Century Farmsteads, Niels R. Rinehart Dec 2013

Assumptions About Consumption In The Archaeology Of Late Nineteenth-Century Farmsteads, Niels R. Rinehart

Northeast Historical Archaeology

Farming is typically associated with rural environments. The Dubois Site in Albany, New York, however, presented an opportunity to look at a farmstead close to a growing urban center during the second half of the 19th century. The excavations of the Dubois Site are discussed and the results are compared to the more rural Porter Site, a contemporary 19th-century farmstead. The comparison examines how the different contexts might have impacted consumption and production at the two farms, as well as the treatment of the farmstead landscapes. The two New York sites are then contrasted with four contemporary farm sites in …


The Mother Of The Father Of Our Country: Mary Ball Washington's Genteel Domestic Habits, Laura J. Galke Dec 2013

The Mother Of The Father Of Our Country: Mary Ball Washington's Genteel Domestic Habits, Laura J. Galke

Northeast Historical Archaeology

The year 1743 brought hardship to the Washingtons as their family patriarch, Augustine, passed away unexpectedly. At that time, a young George Washington inherited the family’s home plantation in Fredericksburg, known today as Ferry Farm. Augustine’s will stipulated that George’s mother, Mary Ball Washington, manage the plantations of their four young boys until they came of age. Between 1743 and 1772, Mary enjoyed the personal agency that widowhood allowed her; she was responsible for the management decisions of the Washington household and the surrounding farm. Mary’s choices reflect an ambitious woman determined to participate in the genteel society her family …
