Inner Workings Of Milankovitch Cycles, Linda A. Hinnov

Sustainability Seminar Series

Milankovitch cycles are incoming solar radiation (insolation) cycles forced by variations in Earth’s orbital eccentricity, axial obliquity and precession, and are recorded on Earth in cyclostratigraphy. Insolation undergoes major daily and annual cycles with weak modulation from the obliquity variation. Thresholds in the Earth’s climate response to insolation generate the strong precession signals commonly observed in cyclostratigraphy. Dr. Hinnov will demonstrate these and other features using the insolation equation, and will discuss the manifestation of these features in key cyclostratigraphic sections.

Cultural Legacies In The Amazonian Holocene: A Paleoecological Perspective, S. Yoshi Maezumi

Sustainability Seminar Series

The extent to which Indigenous land use and cultural burning practices have altered modern ecosystems is a hotly debated topic in archaeology and paleoecology. To address this issue, an interdisciplinary approach combining archaeological, archaeobotany, palaeoecolgoy, and palaeoclimatology is used to investigate climate-human-ecosystem interactions in the Amazon. These data indicate Indigenous Amazonians employed diverse subsistence strategies that combined cultural burning, agroforestry, polyculture, and soil amelioration that maximized subsistence diversity without large-scale land clearing. These data provide evidence of resource diversification, improved food security, and sustainable anthropogenic landscapes during increased climate variability and expanding Indigenous populations during the late Holocene. These data …

Reaction Steps In Heterogeneous Photocatalytic Oxidation Of Toluene In Gas Phase—A Review, Yerzhigit Tulebekov, Zhandos Orazov, Bagdat Satybaldiyev, Daniel D. Snow, Raphaël Schneider, Bolat Uralbekov

Nebraska Water Center: Faculty Publications

A review of the current literature shows there is no clear consensus regarding the reaction mechanisms of air-borne aromatic compounds such as toluene by photocatalytic oxidation. Potential oxidation reactions over TiO₂ or TiO₂-based catalysts under ultraviolet and visible (UV/VIS) illumination are most commonly considered for removal of these pollutants. Along the pathways from a model pollutant, toluene, to final mineralization products (CO₂ and H₂O), the formation of several intermediates via specific reactions include parallel oxidation reactions and formation of less-reactive intermediates on the TiO₂ surface. The latter may occupy active adsorption sites and …

Pumping-Induced Drawdown Of Streams In Proximity To Agricultural Wells, Sara Alina Sternberg

Master of Science in Environmental Sciences and Management Projects

In the context of unprecedented drought and aquifer overdraft in California, understanding surface water and groundwater connectivity have become increasingly important. While there is a clear understanding of how wells induce drawdown in aquifers (Theis, 1935; Hantush, 1965), secondary effects on local streams have not fully been considered. Current mathematical models targeting aquifer drawdown do not address stream drawdown response in aquifer-stream systems with strong connectivity; instead, they assume the stream to be a constant head boundary. In the drought-stricken and summer-dry climate of California, streams often run dry for months out of the year, which is currently not reflected …
