Identifying The Isotopic Signature Of Lake-Effect Precipitation In Shallow Groundwater, Andrew Brown May 2022

Identifying The Isotopic Signature Of Lake-Effect Precipitation In Shallow Groundwater, Andrew Brown

Honors Projects

Three different stable isotopes of water occur in nature, with the majority of water on Earth containing the oxygen isotope 16O. These isotopes have slightly differing physical and chemical properties. H2O with heavier oxygen isotopes should theoretically precipitate earlier than lighter isotope H2O, meaning this natural process should allow for the observation of the magnitude of effects of lake-effect precipitation on the basis of water isotope differences. Furthermore, it may allow for better understanding of the significance lake-effect precipitation plays in recharging shallow aquifers. In this study, patterns of lake-effect precipitation from Lake Michigan were observed in a collection of ...

This study focuses on analyzing three objectives: 1) To explore the potential of Agrivoltaic Farming (dual use) on preserved farmland in New Jersey. 2) To estimate the Levelized Cost of Energy (LCOE) of New Jersey’s dual use potential. 3) To generate sensitivity analyses of dual use solar and farm production in New Jersey. This study analyzed New ...


Grasslands For Production And The Environment, David R. Kemp, David L. Michalk Mar 2022

Grasslands For Production And The Environment, David R. Kemp, David L. Michalk

International Grassland Congress Proceedings

Key points

1. To manage grasslands for production and enhanced environmental values requires a redefinition of the frameworks within which management decisions are made, and a tailoring of practices to suit the ways that farmers operate.

2. Improving the perenniality and permanence of grasslands usually leads to better environmental and production outcomes.

3. There is a case for a more conservative approach to utilising grasslands in order to sustain the functioning of local ecosystems and to improve water quality, nutrient and energy cycling and biodiversity.

4. A landscape rather than paddock focus is more appropriate for meeting current grassland management ...

A Theoretical Study Of Synchronous Proton Transfer In (Hf)N, (H2O) N, And (Hcl) N Where N = 3, 4, 5, Johnny Yang

Honors Theses

For (HF)n, (H2O)n, and (HCl)n (n = 3 − 5), we have rigorously characterized the structures for the minima and transition states for synchronous proton transfer (SPT) with the CCSD(T) method and aug-cc-pVTZ basis set. The electronic barrier heights (∆E) associated with these transition states have also been computed with the explicitly correlated CCSD(T)-F12 method and the aug-cc-pVQZ-F12 basis set (abbreviated aQZ-F12). (HCl)n (n = 3 − 5) SPT transition states have not been previously identified to the best of our knowledge, and they have been found to have D3h, D2d ...


Terra Dispositions: A Lithospheric Investigation Of Wet-Matter, Alec Rovensky May 2021

Terra Dispositions: A Lithospheric Investigation Of Wet-Matter, Alec Rovensky

Architecture Senior Theses

Human intervention of the landscape by damming, filling wetlands and over-extracting is resulting in the rapid perversion of water bodies through the desertification or flooding of terrain and the ensuing contamination of reservoirs. In turn, these changes are disrupting ecosystems, reshaping geological borders, and causing irreversible damage that poses a threat to clean water supplies. As humans exert agency over local hydrology, there is scarce consideration of the ensuing ecological consequences. This thesis aims to expose the ecological transformations of territories laced with human agency by examining the residues left by water in order to deviate from the misplaced nostalgia ...


Can CP Be Less Than CV?, Yingbin Ge, Samuel L. Montgomery, Gabriel L. Borrello Apr 2021

Can CP Be Less Than CV?, Yingbin Ge, Samuel L. Montgomery, Gabriel L. Borrello

All Faculty Scholarship for the College of the Sciences

Can CP be less than CV? This is a fundamental question in physics, chemistry, chemical engineering, and mechanical engineering. This question hangs in the minds of many students, instructors, and researchers. The first instinct is to answer “Yes, for water between 0 and 4 °C” if one knows that water expands as temperature decreases in this temperature range. The same question is asked in several Physical Chemistry and Physics textbooks. Students are supposed to answer that water contracts when heated at below 4 °C in an isobaric process. Because work is done to the contracting water, less heat ...


Carbonatite Metasomatism And Water Systematics Of Peridotite Xenoliths From Lanzarote, Canaries, Sierra N. Patterson Apr 2021

Carbonatite Metasomatism And Water Systematics Of Peridotite Xenoliths From Lanzarote, Canaries, Sierra N. Patterson

Theses and Dissertations

Water in Earth’s mantle, present as structurally bound hydrogen in minerals, influences large scale processes like mantle deformation, plate tectonics, and melting. To better understand the processes controlling water concentrations in the Earth’s upper mantle, we analyzed hydrogen (calculated as ppm wt. H2O), major, and trace element concentrations in minerals from peridotite mantle xenoliths of Lanzarote, Canaries. The Canaries Islands are thought to be the surface expression of a deep-seated mantle plume erupting through the Atlantic Ocean lithosphere. Carbonatite magmas have erupted in the Canaries and previous studies have shown evidence for carbonatite metasomatism in Lanzarote ...

How And Why Mars Lost Its Water, Sana Akhter, Andre Beikircher Feb 2021

How And Why Mars Lost Its Water, Sana Akhter, Andre Beikircher

2021 Honors Council of the Illinois Region

The topic of this paper is to investigate how and why Mars lost its water. It is important to study the loss of water on Mars because it can give us a better understanding of how Mars once looked, if life were possible, and how it could have changed so drastically to what it is now. The paper aims to address which factors led to Mars losing its water and how long ago this happened. Using our data, we will predict how quickly Mars’ core cooled, when its magnetic field weakened, and when the water was lost. We learned that ...

Spatiotemporal Patterns In Water Yield From The Humid Puna: A Case Study In The Agrarian District Of Zurite, Perú, Wyeth Wunderlich

Cal Poly Humboldt theses and projects

The humid puna is a seasonally dry alpine grass- and shrub-land biome that exists at the altitudinal limits of plant survival, hosts peat-forming wetlands known as bofedales, and yields water to streams used by small and large communities throughout the central and southern Peruvian Andes. Despite the importance of the humid puna in supplying water resources, particularly to perennial streams, few studies have quantified water yield and no studies have explored relationships between the structure of puna landscapes and spatial patterns in water yield. Zurite (population: 3,640, elevation: 3,011 m.a.s.l., annual precipitation: 855 mm) is ...

Aggregation And Degradation Of Dispersants And Oil By Microbial Exopolymers (Addomex): Toward A Synthesis Of Processes And Pathways Of Marine Oil Snow Formation In Determining The Fate Of Hydrocarbons, Antonietta Quigg, Peter H. Santschi, Chen Xu, Kai Ziervogel, Manoj Kamalanathan, Wei-Chun Chin, Adrian B. Burd, Andrew Wozniak, Patrick G. Hatcher

Chemistry & Biochemistry Faculty Publications

Microbes (bacteria, phytoplankton) in the ocean are responsible for the copious production of exopolymeric substances (EPS) that include transparent exopolymeric particles. These materials act as a matrix to form marine snow. After the Deepwater Horizon oil spill, marine oil snow (MOS) formed in massive quantities and influenced the fate and transport of oil in the ocean. The processes and pathways of MOS formation require further elucidation to be better understood, in particular we need to better understand how dispersants affect aggregation and degradation of oil. Toward that end, recent work has characterized EPS as a function of microbial community and ...


Water Pollution And Environmental Concerns In Anesthesiology, Marc Kostrubiak, Christine Vatovec, Lesley-Ann Dupigny-Giroux, Donna Rizzo, William Paganelli, Mitchell Tsai Jan 2021

Water Pollution And Environmental Concerns In Anesthesiology, Marc Kostrubiak, Christine Vatovec, Lesley-Ann Dupigny-Giroux, Donna Rizzo, William Paganelli, Mitchell Tsai

Larner College of Medicine Fourth Year Advanced Integration Teaching/Scholarly Projects

Medications administered by anesthesia health care providers and subsequently excreted into the water supply system have the potential to affect ecological systems. Presently, there is a lack of literature examining which medications or metabolites enter the waste stream. Further, assessments of their potential environmental impact are often unknown or simply not considered as an externality of medical practice. Recent work examining the practice of anesthesiology has explored the solid waste stream, and the global warming potential of anesthetic gases, however the potential aquatic impacts remain unexplored. To address the potential for waterborne pollution and environmental toxicity, we extracted the total ...

Hydrologic Investigation Of The Chiwaukee Prairie (Wisconsin) Restoration, Nick Potter

Dissertations, Master's Theses and Master's Reports

Wetlands are a vital component of the landscape, a keystone ecosystem, that are prone to degradation and destruction with urbanization. As a result, significant efforts from communities, scientists, sportsmen and government agencies have been made to protect and restore wetlands. In 2019, The Nature Conservancy began re-wetting, contouring, and seeding a 55-ha parcel of farmland in Pleasant Prairie, Wisconsin, restoring the site in an attempt to resemble pre-settlement conditions. The Nature Conservancy Restoration site is part of the groundwater recharge zone of Chiwaukee Prairie and its restoration aimed to increase the available groundwater for adjacent Chiwaukee Prairie State Natural Area ...


Analysis Of Water Concentration Formed Within Deformed Synthetic Quartz Crystals, Andrew Steward Jan 2021

Analysis Of Water Concentration Formed Within Deformed Synthetic Quartz Crystals, Andrew Steward

Williams Honors College, Honors Research Projects

Analyzing the strength of synthetic quartz is essential to understanding the strength of natural milky quartz, which likely controls the strength of Earth’s continental crust. Synthetic quartz is sometimes used for deformation experiments because it has a homogenous water distribution unlike natural milky quartz. The purpose of this study is to determine if annealing synthetic quartz at T = 600°C will convert the water in synthetic quartz to free water, like milky quartz, but with little water loss. Following two annealing experiments at Texas A&M University, I performed four annealing experiments to measure the water content of five ...


The Waterfall Crisis, Guiliana G. Grisaffi Nov 2020

The Waterfall Crisis, Guiliana G. Grisaffi

English Department: Research for Change - Wicked Problems in Our World

While the Earth’s surface is 71% covered in water, that does not mean that one day all our water could be gone. The current global water crisis is not just a water crisis-it is a waterfall crisis. One wicked, terrible problem that leads to many other wicked problems, a waterfall crisis. Millions of women and young girls are taken out of work and school and instead forced to collect and gather fresh water for their families. Children are suffering from irreversible health consequences from toxic, contaminated water, an example of a health consequence is a lower IQ from lead ...


Protein Conformational Entropy Is Not Slaved To Water, Bryan S Marques, Matthew A Stetz, Christine Jorge, Kathleen G Valentine, A Joshua Wand, Nathaniel V Nucci Oct 2020

Protein Conformational Entropy Is Not Slaved To Water, Bryan S Marques, Matthew A Stetz, Christine Jorge, Kathleen G Valentine, A Joshua Wand, Nathaniel V Nucci

Faculty Scholarship for the College of Science & Mathematics

Conformational entropy can be an important element of the thermodynamics of protein functions such as the binding of ligands. The observed role for conformational entropy in modulating molecular recognition by proteins is in opposition to an often-invoked theory for the interaction of protein molecules with solvent water. The "solvent slaving" model predicts that protein motion is strongly coupled to various aspects of water such as bulk solvent viscosity and local hydration shell dynamics. Changes in conformational entropy are manifested in alterations of fast internal side chain motion that is detectable by NMR relaxation. We show here that the fast-internal side ...


Mxenes As Flow Electrodes For Capacitive Deionization Of Wastewater, Naqsh E. Mansoor Aug 2020

Mxenes As Flow Electrodes For Capacitive Deionization Of Wastewater, Naqsh E. Mansoor

Boise State University Theses and Dissertations

The energy-water nexus poses an integrated research challenge, while opening up an opportunity space for the development of energy efficient technologies for water remediation. Capacitive Deionization (CDI) is an upcoming reclamation technology that uses a small applied voltage applied across electrodes to electrophoretically remove dissolved ionic impurities from wastewater streams. Similar to a supercapacitor, the ions are stored in the electric double layer of the electrodes. Reversing the polarity of applied voltage enables recovery of the removed ionic impurities, allowing for recycling and reuse. Simultaneous materials recovery and water reclamation makes CDI energy efficient and resource conservative, with potential to ...
