A Geographical Approach For Integrating Belief Networks And Geographic Information Sciences To Probabilistically Predict River Depth, Nathan Lee Hopper

Dissertations

Geography is, traditionally, a discipline dedicated to answering complex spatial questions. Although spatial statistical techniques, such as weighted regressions and weighted overlay analyses, are commonplace within geographical sciences, probabilistic reasoning, and uncertainty analyses are not typical. For example, belief networks are statistically robust and computationally powerful, but are not strongly integrated into geographic information systems. This is one of the reasons that belief networks have not been more widely utilized within the environmental sciences community. Geography’s traditional method of delivering information through maps provides a mechanism for conveying probabilities and uncertainties to decision makers in a clear, concise manner. This …

Hydrogeological And Thermal Sustainability Of Geothermal Borehole Heat Exchangers, S. Emad Dehkordi

Electronic Thesis and Dissertation Repository

Assessment of the current approach taken by guidelines and design methods of vertical closed loop heat exchangers shows that often groundwater flow is either disregarded or is not methodically incorporated. The state of scientific research in this arena reveals that overlooking the groundwater flow in the design procedure may not always be a correct assumption. The significance of advective heat transport compared to conduction is defined by the groundwater flux or Darcy velocity which heavily depends on the hydraulic conductivity of the ground, followed by the hydraulic gradient which has a relatively limited range. A sensitivity analysis on ground and …

Global Fossil Energy Markets And Climate Change Mitigation: An Analysis With Remind, Nico Bauer, Ioanna Mouratiadou, Gunnar Luderer, Lavinia Baumstark, Robert J. Brecha, Ottmar Edenhofer, Elmar Kriegler

Physics Faculty Publications

We analyze the dynamics of global fossil resource markets under different assumptions for the supply of fossil fuel resources, development pathways for energy demand, and climate policy settings. Resource markets, in particular the oil market, are characterized by a large discrepancy between costs of resource extraction and commodity prices on international markets. We explain this observation in terms of (a) the intertemporal scarcity rent, (b) regional price differentials arising from trade and transport costs, (c) heterogeneity and inertia in the extraction sector. These effects are captured by the REMIND model. We use the model to explore economic effects of changes …

Biochar has been in existence for thousands of years. However, it has only been in the past decade that there has been a resurgence in the thirst for knowledge about biochar and research into how it is made and its impact on the environment.

This resurgence has brought about a tremendous amount of research and a rapid growth in education among the general population about biochar – especially in the past …

Rescuing biochar: Pre - application techniques to enhance plant responses to biochar additions: Nigel Gale, U of Toronto

A growing body of literature indicates variable responses of different plant species to biochar, including positive, neutral, and negative, suggesting that it is important to investigate the nature and mechanism of species-specific responses to biochar additions. Neutral or negative plant responses to additions of biochars have commonly been reported in prior studies, and are likely the result of a combination of changes in soil properties (e.g. pH, surface area, and nutrient and water retention) and the production of volatile organic compounds from …

Cascading Uses of Biochar - Hans-Peter Schmidt, Ithaka Institute

In addition to the use of biochar as a soil amendment, there are an increasing number of ways to incorporate biochar into different eco- and industrial systems. Thus feeding biochar to livestock has numerous benefits not only for the animals, but it also helps reduce greenhouse gas emissions and improves nutrient retention in animal manure. The use of biochar in building materials is just beginning to be studied but shows promise in the ability to insulate, decontaminate air, provide odor and humidity control. Biochar as pillow filling to induce perfectly reposing …

Ethics & Sustainability, Gloria Flora, John Bonitz, Karen Ribeiro

USBI Biochar Conferences

Biochar and the Sustainability Imperative. Now marks a critical time: as biochar comes of age and markets begin to develop, this young industry is attracting naysayers, doubters and get-rich-quick-schemers. Ethical biochar production and use is of paramount importance as we continue to lay the groundwork for biochar as a model for carbon neutral/negative business, landscape restoration and truly green technology. Shortcuts, poor quality product and unsustainable use of biomass could bring biochar to its knees before it gains the traction necessary to fulfill its promises. This discussion will explore opportunities and pitfalls in feedstocks sustainability, production integrity and ethics in …

Sorptive Treatment of Metals and Nitro Explosives in Water Using Biochar -

Seok-Young Oh^1*,

Biochar, a solid byproduct of a pyrolysis process was investigated as a sorbent to remove toxic metals and nitro explosives from natural water and wastewater. It was hypothesized that biochar can sorb dissolved metals and nitro explosives due to its high surface area and strong sorption affinity of aromatic organic compounds. Using a tube furnace under N₂, various types biochar were synthesized by changing biomass (poultry litter, sludge, fallen leaves, corn stalk, rice straw, and coffee grounds) and temperature (250, 400, …

Environmental Factors Influencing Diatom Communities In Antarctic Cryoconite Holes, Lee F. Stanish, Elizabeth A. Bagshaw, Diane M. Mcknight, Andrew G. Fountain, Martyn Tranter

Geology Faculty Publications and Presentations

Cryoconite holes are ice-bound habitats that can act as refuges for aquatic and terrestrial microorganisms on glacier surfaces. In the McMurdo Dry Valleys of Antarctica, these holes are often capped by an ice lid that prevents the exchange of material and gases with the surrounding atmosphere and aquatic environment. Diatoms have been documented in cryoconite holes, and recent findings suggest that these habitats may harbour a distinctive diatom flora compared to the surrounding aquatic environments. In this study, we examined diatom community composition in cryoconite holes and environmental correlates across three glaciers in Taylor Valley, Antarctica. The diatom communities were …
