Exposure To Pesticides And Hepatocellular Carcinoma (Hcc) Risk In And Around Monroe County, Ny, Theodros Woldeyohannes Dec 2020

Exposure To Pesticides And Hepatocellular Carcinoma (Hcc) Risk In And Around Monroe County, Ny, Theodros Woldeyohannes

Theses

The impact of long-term exposure and persistence of pesticides in the environment on human biology is not completely understood. With the proliferation of pesticide application technologies, there have been documented associations between exposure to every major functional group of pesticide and adverse health effects in humans such as cancer and neurological disease. Of observed pesticide-induced cancer health-risks, hepatocellular carcinoma (HCC) has shown some of the most significant associations. Epidemiological study is complex, especially when examining pesticide health risks. It is difficult to understand the significance behind interactions between the large list of pesticide compounds, external environmental factors, and biological variables. …


Ecological Impacts Of Food Waste Digestate Management In An Agricultural Watershed, Shradha Shrestha Jun 2020

Ecological Impacts Of Food Waste Digestate Management In An Agricultural Watershed, Shradha Shrestha

Theses

Globally, more than two billion tons of food are wasted each year, creating significant economic and environmental issues. Anaerobic digestion (AD), a process to convert organic waste to biogas, is a potential waste-to-energy alternative to landfilling wasted food (FW). Liquid digestate, a by-product of AD, is typically stored on-site in ponds prior to field application as a fertilizer, presenting risks of greenhouse gas (GHG) emissions and nutrient release to sensitive waterways. To assess this risk, we used a co-digestion (FW plus manure) facility and associated row-crop disposal system in an agricultural watershed in western New York, USA as a case …


Revising A Habitat Suitability Model For Spotted Turtles (Clemmys Guttata) In Upstate New York, Caitlin Dailey Jan 2017

Revising A Habitat Suitability Model For Spotted Turtles (Clemmys Guttata) In Upstate New York, Caitlin Dailey

Theses

In order to protect threatened and endangered species, their habitat needs to be adequately documented and assessed for conservation planning. The utilization of mapping programs such as ArcGIS can help researchers in determining the most optimal sites for a particular species in a given area. This research revises a previous habitat suitability model by Correa-Berger (2007) for the spotted turtle (Clemmys guttata) in nine counties of upstate New York. Using the same initial parameters for the creation of the seed sites and habitat requirements for spotted turtles that Correa-Berger used in his 2007 analysis, the model utilized updated Land Use/Land …


Using Geographic Information Systems To Identify Habitat For The Golden-Winged Warbler (Vermivora Chrysoptera) In Western New York, Jesse Michael Rubenstein Sep 2016

Using Geographic Information Systems To Identify Habitat For The Golden-Winged Warbler (Vermivora Chrysoptera) In Western New York, Jesse Michael Rubenstein

Theses

The Golden-winged Warbler (Vermivora chrysoptera) is a passerine species whose populations have decreased internationally by approximately 66 percent since the 1960s, and by approximately 50 percent in New York. Major causes for declines are from loss of shrubland habitat and through hybridization with the Blue-winged Warbler (Vermivora cyanoptera). This study utilized published data and expert opinion on Golden-winged Warbler (GWWA) habitat requirements to create habitat suitability models within the Western Finger Lakes Region of NY (NYSDEC Region 8) using a geographic information system. This region is an important area for migratory birds and is previously unstudied for GWWA. The concentration …


Large Scale Archaeological Satellite Classification And Data Mining Tools, Kelly Canham Nov 2012

Large Scale Archaeological Satellite Classification And Data Mining Tools, Kelly Canham

Theses

Archaeological applications routinely use many different forms of remote sensing imagery, the exception being hyperspectral imagery (HSI). HSI tends to be utilized in a similar fashion as multispectral imagery (MSI) or processed to the point that it can be utilized similarly to MSI, thus reducing the benefits of HSI. However, for large scale archaeological surveys, HSI data can be used to differentiate materials more accurately than MSI because of HSI's larger number of spectral bands. HSI also has the ability to identify multiple materials found within a single pixel (sub-pixel material mixing), which is traditionally not possible with MSI. The …


Freight Transportation And The Environment: Using Geographic Information Systems To Inform Goods Movement Policy, Arindam Ghosh Jan 2011

Freight Transportation And The Environment: Using Geographic Information Systems To Inform Goods Movement Policy, Arindam Ghosh

Theses

The freight transportation sector is a major emitter of the greenhouse gas carbon dioxide (CO2) which has been recognized by numerous experts and science organizations as a significant contributor to climate change. The purpose of this thesis is to develop a a framework for obtaining the freight flows for containerized goods movement through the U.S. marine, highway, and rail systems and to estimate CO2 emissions associated with the freight traffic along interstate corridors that serve the three major U.S. ports on the West Coast, namely the port of Los Angeles and Long Beach, the Port of Oakland and the Port …


An Evaluation Of Energy Consumption And Emissions From Intermodal Freight Operations On The Eastern Seaboard: A Gis Network Analysis Approach, Aaron Falzarano Sep 2008

An Evaluation Of Energy Consumption And Emissions From Intermodal Freight Operations On The Eastern Seaboard: A Gis Network Analysis Approach, Aaron Falzarano

Theses

As global trade continues to increase, the energy and environmental impacts of freight movement in the US have become more of a concern. As such, the freight transport system needs to consider opportunities to meet customer objectives, while also meeting social goals. In the US there has been legislation enacted to address the growing impact that freight movement has on the environment, but there are limited tools to assist in the implementation of those polices. This research sets forth a process for creating a geospatial intermodal freight transportation (GIFT) model within ArcGIS that can be used to analyze freight movement …


Health Impacts From Diesel Freight Emissions: Development Of A Geospatial Analytical Framework For Policy Evaluation With A Case Study Of Sacramento, Ca, Colin Murphy May 2008

Health Impacts From Diesel Freight Emissions: Development Of A Geospatial Analytical Framework For Policy Evaluation With A Case Study Of Sacramento, Ca, Colin Murphy

Theses

Diesel particulate matter, emitted by many types of freight transport, poses a health risk to populations living near freight activity. Accurate information about the magnitude and location of health impacts would help inform policy decisions at a number of levels. Existing methods, including atmospheric dispersion modeling, epidemiology or air quality measurement can estimate the magnitude of harm experienced by populations but these methods often require resources or expertise beyond the reach of some stakeholders, particularly those at local levels. This thesis describes a framework by which health impact estimation can be carried out utilizing readily available models and methodologies in …
