Silence Is The Loudest Sound, Emma Christian

Honors College

Rhinoceros poaching is an act of killing a rhinoceros in order to take its horn, which is then used for human consumption or for cultural traditions. Both the Asian and the African rhinoceros are targets because of the demand from China, Vietnam, Yemen, and other countries around the world. Traditional Chinese Medicine practice is the main demand for rhinoceros horn and this demand in rhinoceros horn has caused an increase in the black market. Conservation of the rhinoceros is decreasing primarily because the price of rhinoceros horn is more than double the average household income in South Africa, thus making ...


A Regression Approach For Estimation Of Anthropogenic Heat Flux Based On A Bottom-Up Air Pollutant Emission Database, Sang-Hyun Lee, Stuart A. McKeen, David J. Sailor 2014 Portland State University

A Regression Approach For Estimation Of Anthropogenic Heat Flux Based On A Bottom-Up Air Pollutant Emission Database, Sang-Hyun Lee, Stuart A. Mckeen, David J. Sailor

Mechanical and Materials Engineering Faculty Publications and Presentations

A statistical regression method is presented for estimating hourly anthropogenic heat flux (AHF) using an anthropogenic pollutant emission inventory for use in mesoscale meteorological and air-quality modeling. Based on bottom-up AHF estimated from detailed energy consumption data and anthropogenic pollutant emissions of carbon monoxide (CO) and nitrogen oxides (NOx) in the US National Emission Inventory year 2005 (NEI-2005), a robust regression relation between the AHF and the pollutant emissions is obtained for Houston. This relation is a combination of two power functions (Y = aXb) relating CO and NOx emissions to AHF, giving a determinant coefficient (R2 ...


Precipitation Variability And Nitrogen Deposition Alter Root Distribution In A Tallgrass Prairie, Emmalyn P. Terracciano, Michael Schuster, Jeffrey Dukes 2014 Purdue University

Precipitation Variability And Nitrogen Deposition Alter Root Distribution In A Tallgrass Prairie, Emmalyn P. Terracciano, Michael Schuster, Jeffrey Dukes

The Summer Undergraduate Research Fellowship (SURF) Symposium

Climate change and increases in nitrogen deposition impact ecosystems globally. Projected atmospheric warming allows rain to fall in larger events with longer dry periods in between, increasing rainfall variability in many regions. Concurrently, the combustion of fossil fuels and the heavy use of nitrogen fertilizers continue to increase the availability of nitrogen globally. However, not much is known about how these global change factors, increased rainfall variability and nitrogen deposition, interact with each other to affect ecosystem functions, particularly belowground where root production contributes to soil carbon pools- an important component in regulating climate. In order to study these factors ...


Evaluating Contaminants Of Emerging Concern In Commercial Biosolid-Based Fertilizers, John Hemmerling, Michael L. Mashtare, Linda S. Lee 2014 Purdue University

Evaluating Contaminants Of Emerging Concern In Commercial Biosolid-Based Fertilizers, John Hemmerling, Michael L. Mashtare, Linda S. Lee

The Summer Undergraduate Research Fellowship (SURF) Symposium

The production and popularity of commercially available biosolid-based fertilizers are increasing because of their economic, environmental, and plant nutrition benefits, particularly in urban and suburban areas. Because biosolid-based fertilizers are derived from waste water treatment plant residuals, we hypothesized that there is the potential for micropollutants to persist in these products. Their presence would be of particular concern due to their potential impact on human and ecological health and risk of bioaccumulation. This study involves quantifying contaminants of emerging concern in three biosolid-based fertilizers, and 2 non-biosolid-based fertilizers, a composted animal manure and an organic compost. Our extraction method employed ...

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Shovelnose Sturgeon Scaphirhynchus platorynchus remains the most abundant riverine sturgeon species in North American despite the anthropogenic modifications that have occurred throughout their historic range; however, their populations have declined throughout Nebraska since the construction of Fort Randall and Gavins Point Dams. Therefore, the objective of this study was to present the current status of Shovelnose Sturgeon in the Missouri River along Nebraska’s border. Data was acquired from 2003 to 2012 from all reaches of the Missouri River along Nebraska’s eastern border. Catch rates of Shovelnose Sturgeon increased in a downstream trend and were highest in the ...


Damming Brazil, Thyra Brody 2014 Chapman University

Damming Brazil, Thyra Brody

e-Research: A Journal of Undergraduate Work

Hydroelectric power is often considered a safe and clean alternative to the combustion of fossil fuels. Although the consequences to the air and atmosphere are lower, damming large rivers in the jungles of Brazil have a significant impact on indigenous populations and environmental ecosystems. This article examines such fallout and calls out for equity, and social and environmental justice. As the fuel of the last century burns out the hectic scramble for a tenable alternative is becoming an increasingly serious question mark. We would do well for ourselves, and future generations, to try and solve the environmental issues associated with ...


Utilizing Remote Sensing To Detect Deepwater Horizon Oil Spill Properties, Amanda Kristedja 2014 Chapman University

Utilizing Remote Sensing To Detect Deepwater Horizon Oil Spill Properties, Amanda Kristedja

e-Research: A Journal of Undergraduate Work

This paper focuses on the detection of oil spills using satellite information. ��For this research project, the focus will be primarily on the Deepwater Horizon Oil Spill, which is the largest accidental oil spill. In order to detect an oil spill, the chlorophyll a content must be observed with data from the SeaWiFs at 9km and the MODIS-aqua at 9km and 4km. There is conflicting evidence of whether or not chlorophyll a concentration is positively correlated with the presence of an oil spill. This will be further investigated in the experiment. Also, by utilizing the MODIS instrument aboard the terra ...

Promoting Renewable Energy Generation In The United States: The Debate Over Renewable Portfolio Standards, Joe Cerne 2014 University of Puget Sound

Promoting Renewable Energy Generation In The United States: The Debate Over Renewable Portfolio Standards, Joe Cerne

Economics Theses

Incentivizing renewable energy growth in the 21st century is, and will continue to be, a highly debated topic. As of late, legislative initiatives have prompted the enactment of various renewable portfolio standards aimed at stimulating renewable energy growth. Using data regarding each state’s energy production, this paper finds that there is no significant change in renewable energy output following the initiation of a renewable portfolio standard. We conclude that renewable energy growth is virtually unaffected by renewable portfolio standards and as such, we agree with much of the literature implying other means are necessary in order to adequately ...

An Economic Analysis Of Small-Scale Biodiesel Production: Implementation Of Ethyl Ester Production In A Job Shop Setting, Scott Haase, Benjamin Craig

Journal of Undergraduate Research at Minnesota State University, Mankato

Biodiesel is becoming a demanded consumer automotive alternative fuel used in diesel vehicles today. An emerging trend is toward small-scale biodiesel production performed by the final consumer. A limited source of commercially available production systems exists and has resulted in many systems being designed and built by the user. Preliminary research conducted by the authors has shown biodiesel to be the least-cost alternative to petroleum diesel after as few as 8 months of system use. This study examines the economic viability of building and producing biodiesel using a small-scale production system versus buying consumer petroleum diesel. During production, measurements were ...

Fluid Properties In The Formation Of High-Grade Iron Ore In Northern Minnesota, Elizabeth Drommerhausen 2014 Minnesota State University, Mankato

Fluid Properties In The Formation Of High-Grade Iron Ore In Northern Minnesota, Elizabeth Drommerhausen

Journal of Undergraduate Research at Minnesota State University, Mankato

The Mesabi Iron Range in Northern Minnesota has been a major producer of iron ore for over 100 years. Production has been from the 1.85 – billion-year –old Biwabik Iron Formation, an iron-rich sedimentary rock that is tilted gently to the south. Most of the known high-grade ore lies near the surface and has been already mined. Determining whether more high-grade ore may lie at depth could have significant economic impact on the mining industry in northern Minnesota. To evaluate the likelihood of finding more high-grade iron ore deeper underground, it is important to determine the source of the fluids ...

Environmental Science and Management Faculty Publications and Presentations

Disturbance regimes within temperate forests can significantly impact carbon cycling. Additionally, projected climate change in combination with multiple, interacting disturbance effects may disrupt the capacity of forests to act as carbon sinks at large spatial and temporal scales. We used a spatially explicit forest succession and disturbance model, LANDIS-II, to model the effects of climate change, gypsy moth (Lymantria dispar L.) defoliation, and wildfire on the C dynamics of the forests of the New Jersey Pine Barrens over the next century. Climate scenarios were simulated using current climate conditions (baseline), as well as a high emissions scenario (HadCM3 A2 emissions ...


Uncovering The Influence Of Household Sociodemographic And Behavioral Characteristics On Summer Water Consumption In The Portland Metropolitan Area, Chang-yu Hong, Heejun Chang 2014 University of Wisconsin Milwaukee

Uncovering The Influence Of Household Sociodemographic And Behavioral Characteristics On Summer Water Consumption In The Portland Metropolitan Area, Chang-Yu Hong, Heejun Chang

International Journal of Geospatial and Environmental Research

As urban areas continue to expand, sustainable urban water resource management has become an important issue in green and sustainable city planning. Using single-family residential (SFR) household survey, we identified the determinants of household summer daily water consumption from 2000 to 2005 in Portland, Oregon. The multiple regression results show that approximately 41% of variations in SFR water consumption is explained by average building size, household attitude to water conservation, community engagement of household, and presence of native plants in the garden. The multi-level modeling results show that household attitude to water conservation is an important predictor of SFR water ...


Assessing The Impacts Of Climate Change, Urbanization, And Filter Strips On Water Quality Using Swat, Mike Psaris, Heejun Chang 2014 University of Wisconsin Milwaukee

Assessing The Impacts Of Climate Change, Urbanization, And Filter Strips On Water Quality Using Swat, Mike Psaris, Heejun Chang

International Journal of Geospatial and Environmental Research

Precipitation changes and urban growth are two factors altering the state of water quality. Changes in precipitation will alter the amount and timing of flows, and the corresponding sediment and nutrient dynamics. Meanwhile, densification associated with urban growth will create more impervious surfaces which will alter sediment and nutrient loadings. Land and water managers rely on models to develop possible future scenarios and devise management responses to these projected changes. We use the Soil and Water Assessment Tool (SWAT) to assess potential changes in stream flow, sediment, and nutrient loads in two urbanizing watersheds in Northwest Oregon, USA. We evaluate ...


Municipal Recycling In Waterville: A Choice Experiment, Katharine V. Eddy, Alec A. Finigan 2014 Colby College

Municipal Recycling In Waterville: A Choice Experiment, Katharine V. Eddy, Alec A. Finigan

Journal of Environmental and Resource Economics at Colby

The city of Waterville, Maine has experienced many struggles with establishing an economically and socially beneficial method for collecting recyclables from residents. In 2006, the town made the choice to terminate its curbside recycling pickup and open the Skills facility, where residents were able to transport there recyclables and dispose of them at the facility. This proved to also not be economically beneficial and the town ended this option for residents in 2012. The motivation behind establishing a new recycling program in Waterville is making Waterville more environmentally friendly, the creation of jobs for residents in the trash collecting business ...
