Identifying Cultural and Non-cultural Factors Affecting Litter Patterns in Hickory Creek, Texas

Carpenter, Evan S. 08 1900 (has links)
Plastic deposition in hydrological systems is a pervasive problem at all geographic scales from loci of pollution to global ocean circulation. Much attention has been devoted to plastic deposition in marine contexts, but little is known about inputs of plastics into local hydrological systems, such as streams. Any attempt to prevent plastic litter must confront people’s behaviors, so archaeological concepts are used to distinguish between various cultural inputs (e.g., littering) and non-cultural forces (e.g., stream transport) that affect litter patterns on the landscape. Litter surveys along Hickory Creek in Denton, TX, are used to assess these factors.

Differential use of space: An analysis of the Aubrey Clovis site.

Witt, Benjamin A. 08 1900 (has links)
The Aubrey Clovis site is one of the oldest late-Pleistocene sites in North America, dated to ~11,550 B.P., and contains two camps with a range of lithic debitage, numerous hearths, and excellent faunal preservation. Couched in rules of classification, a series of artifact distributions are analyzed with qualitative and quantitative techniques, including maps produced in a geographic information system (GIS) and tests of artifact associations using correlation statistics. Theoretical and methodological protocols are promoted to improve spatial analysis in archaeology. The results support the short-term occupation interpretation and expose the differential patterning among bone, stone, and raw materials distributions. The spatial structure and diverse content of the site challenge models of Clovis-age people as strictly big game hunters.

Characterizing Storm Water Runoff from Natural Gas Well Sites in Denton County, Texas

Wachal, David J. 05 1900 (has links)
In order to better understand runoff characteristics from natural gas well sites in north central Texas, the City of Denton, with assistance through an EPA funded 104b3 Water Quality Cooperative Agreement, monitored storm water runoff from local natural gas well sites. Storm water runoff was found to contain high concentrations of total suspended solids (TSS). Observed TSS concentrations resulted in sediment loading rates that are similar to those observed from typical construction activities. Petroleum hydrocarbons, in contrast, were rarely detected in runoff samples. Heavy metals were detected in concentrations similar to those observed in typical urban runoff. However, the concentrations observed at the gas well sites were higher than those measured at nearby reference sites. Storm water runoff data collected from these sites were used to evaluate the effectiveness of the water erosion prediction project (WEPP) model for predicting runoff and sediment from these sites. Runoff and sediment predictions were adequate; however, rainfall simulation experiments were used to further characterize the portion of the site where drilling and extraction operations are performed, referred to as the "pad site." These experiments were used to develop specific pad site erosion parameters for the WEPP model. Finally, version 2 of the revised universal soil loss equation (RUSLE 2.0) was used to evaluate the efficiency of best management practices (BMPs) for natural gas well sites. BMP efficiency ratings, which ranged from 52 to 93%, were also evaluated in the context of site management goals and implementation cost, demonstrating a practical approach for managing soil loss and understanding the importance of selecting appropriate site-specific BMPs.

A Quantitative Chemical Examination of Surface Well Water from the Three Principal Geological Divisions of Denton County

Schnably, John Robert 08 1900 (has links)
A sample of the surface-well water was taken from an area of the predominating soil of each of the three geological regions of Denton County, Texas, and a chemical analysis of each sample was made. This thesis deals with the area from which the samples were taken, the methods of analysis used, and the results of the analysis.

The Cooperative Movement and its Influence in Denton County

Cox, Eli 08 1900 (has links)
Cooperation is a subject which has intrigued the writer for some time. A study of the philosophy, history and accomplishments of the cooperative movement was begun, due to the interest of the study. In Denton County, Texas, the cooperatives have, for the past few years, been making such rapid progress that a study of the inception, growth and success of these societies seemed indicated. In spite of the broad field of study this subjected presented, it seemed necessary to review the cooperative movement before the local cooperatives could be properly interpreted. This was Done. Numerous books and magazine articles pertaining to cooperation were read. In making this library study, the writer tried to delve into the underlying philosophy of the cooperative movement. Those countries in which cooperation has made greatest strides were given particular attention in order to try to find the secret of their success. After this library approach was completed, the various cooperative societies of Denton County were visited. The writer talked with the leaders of the societies, obtained copies of the by-laws of each organization, examined financial statements, and attempted to analyze the purposes, the accomplishments, and the possibilities of the future success of these organizations.

In Vitro Determination of the Cellulose-Decomposing Rates of Twelve Denton County, Texas Soils

Heather, Carl D. 08 1900 (has links)
In this study twelve types of top soil were collected under aseptic conditions. The cellulose-decomposing rates of these were compared in order to determine the relative rates in the cellulose-decomposing potential of the microorganisms involved. Furthermore, this investigation is designed to acquire pertinent information on the rate at which natural cellulose materials are returned to available plant food.
