The Effects Of High Density Septic Systems On Surface Water Quality In Gwinnett County, Georgia, John R. Anderson Ii Dec 2010

The Effects Of High Density Septic Systems On Surface Water Quality In Gwinnett County, Georgia, John R. Anderson Ii

Geosciences Theses

Gwinnett County, Georgia experienced rapid growth in the 1970’s without the infrastructure so septic systems were installed for residential homes. The number of septic systems grew to over 85,000 with a density of 487 septic systems per square mile. This study mapped the distribution of septic systems to determine regions of potential pathogen surface water. This study addressed what potential health risks do high density septic systems have on surface water quality and how can the history of Gwinnett County assist in future development in the Metropolitan Atlanta area? It was found that the density of septic systems has reduced …

K-Ar Age Values Of Bulk Soil Samples And Clay Fractions: Effects Of Acid Extraction And Implications For The Origin Of Micaceous Clay In Savannah River Site Soils, South Carolina, Usa, Thomas E. Naumann Aug 2010

K-Ar Age Values Of Bulk Soil Samples And Clay Fractions: Effects Of Acid Extraction And Implications For The Origin Of Micaceous Clay In Savannah River Site Soils, South Carolina, Usa, Thomas E. Naumann

Geosciences Theses

Understanding how natural Cs, Rb, and K have been redistributed in Savannah River Site (SRS) soils during pedogenesis is important to understanding how radiocesium released to the soils will behave over the long term. In this effort, it is important to distinguish K that has participated in mineral-water reactions from that still residing in primary silicate structures, particularly in the clay fraction. The impact of different degrees of acid extraction on K and radiogenic Ar in bulk soil and in clay from five SRS soil samples has been determined. Strong treatment (50% HNO3, three hours, 100°C) releases K from primary …

Mineralogical And Geochemical Indicators Of Subaerial Weathering In The Pozzolane Rosse Ignimbrite (Alban Hills Volcanic District, Italy), Jennifer M. Dickie Apr 2010

Mineralogical And Geochemical Indicators Of Subaerial Weathering In The Pozzolane Rosse Ignimbrite (Alban Hills Volcanic District, Italy), Jennifer M. Dickie

Geosciences Theses

The Pozzolane Rosse ignimbrite [PR] (457±4 ka) in the Alban Hills Volcanic District, Rome, Italy was exposed ~ 40 ka prior to a subsequent volcanic event which coverd it entirely. XRF, XRD, and clay separation results from PR samples from INGV and CA1 boreholes and Castel di Leva quarry show evidence of paleopedogenesis. All locations display loss of base cations, loss of K is consistent with XRD datat showing dissolution or alteration of leucite to analcime. Accumulation of Al and high L.O.I. support XRD evidence of 1:1 clay species at upper depth. Data suggest alteration extent can be determined by …

Censoring Maps In Google China? Visual Analysis Through Foucault't Power/Knowledge, Zhanar Karimbayeva Apr 2010

Censoring Maps In Google China? Visual Analysis Through Foucault't Power/Knowledge, Zhanar Karimbayeva

Geosciences Theses

This thesis explores aspects of map censorship in Google China through a theoretical framework based on Foucault’s power/knowledge. Comparing results of content analysis of maps in Google Ditu in Google China and Google Maps in Google Dot Com, the thesis analyzes the degree of censorship of maps in the Google geoweb. My findings are a higher density of labeling in Google Ditu in comparison with Google Maps, the absence of VGI in Google Ditu, the limitation of zoom level at Google Ditu, and the absence of Street View in China. This thesis suggests possible explanations to differences in map information …

Ontology And Knowledge Base Of Brittle Deformation Microstructures For The San Andreas Fault Observatory At Depth (Safod) Core Samples, Cynthia Marie Broda Apr 2010

Ontology And Knowledge Base Of Brittle Deformation Microstructures For The San Andreas Fault Observatory At Depth (Safod) Core Samples, Cynthia Marie Broda

Geosciences Theses

The quest to answer fundamental questions and solve complex problems is a principal tenet of Earth science. The pursuit of scientific knowledge has generated profuse research, resulting in a plethora of information-rich resources. This phenomenon offers great potential for scientific discovery. However, a deficiency in information connectivity and processing standards has become evident. This deficiency has resulted in a demand for tools to facilitate and process this upsurge in information. This ontology project is an answer to the demand for information processing tools. The primary purpose of this domain-specific ontology and knowledge base is to organize, connect, and correlate research …

Analysis Of Precipitates And Waters Associated With An Alkaline Leachate, Gulf State Steel Property, Gadsden, Alabama: A Reconnaissance Study, Craig Vantrees Apr 2010

Analysis Of Precipitates And Waters Associated With An Alkaline Leachate, Gulf State Steel Property, Gadsden, Alabama: A Reconnaissance Study, Craig Vantrees

Geosciences Theses

Calcite stalactites ranging in length from several inches to a foot long are found forming on the southeastern slag pile at the former Gadsden Steel Mill of the Gulf States Steel Corporation. Analyses of samples collected per EISOPQAM guidelines include the following: petrographic, conductivity, pH, XRD, XRF, TDS, and major cations and anions. Preliminary field pH and conductivity measurements indicate that waters near the slag pile have a pH ranging from 11-12 and a conductivity ranging from 1115-6300 μS/ cm. Titration data indicate that the maximum pH value is 12.5. These calcite stalactites and stream coatings result from the dissolution …

John Borchert’S “American Metropolitan Evolution”, Risa Palm Jan 2010

John Borchert’S “American Metropolitan Evolution”, Risa Palm

Geosciences Faculty Publications

The article presents comments on the article "American Metropolitan Evolution," originally published in 1967 by the urban geographer John Borchert. Details are given overviewing the thesis and research of the paper, focusing on its discussion of the organizational structure of the four "epochs" of urban development in U.S. history. Discussion is offered explaining the significance of the 1967 paper. The author also highlights the influence which the article had on his own research and of the field at large over 40 years.

Reclaiming A Sense Of Place: Geospatial Technologies And The Flat Rock Cemetery Project, Jeffrey Glover, Kathryn Jackson, Johnny Waits Jan 2010

Reclaiming A Sense Of Place: Geospatial Technologies And The Flat Rock Cemetery Project, Jeffrey Glover, Kathryn Jackson, Johnny Waits

Geosciences Faculty Publications

The Flat Rock community in southern DeKalb County, Georgia (just outside Atlanta) is one of the oldest continually-occupied African-American communities in Georgia. Although history shows that many African-American communities in the South were broken apart as former slaves migrated north in search of jobs and a more equitable life, Flat Rock remained an intact community. This was largely due to the efforts of individuals who were able to purchase land and later sell it in small parcels to fellow community members. Proximity—both to ancestors and significant places—is a cross-culturally important component to the creation of a sense of community. Placed …
