Hydrothermal Preparation Of Gd+3 -Doped Titanate Nanotubes: Magnetic Properties And Photovoltaic Performance, Hoda S. Hafez, M Saif, James T. Mcleskey Jr., M.S.A. Abdel-Mottaleb, I S. Yahia, T Story, W Knoff

Mechanical and Nuclear Engineering Publications

Pure and Gd+3 -doped titanate nanotubes (TNTs) materials were synthesized by a hydrothermal method. Their morphology, optical properties, thermal stability, and magnetic properties were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), UV-Vis spectroscopy, thermal analysis, and magnetic measurements. It was found that doping renders Gd+3-TNT visible light active and results in smaller crystallite size and larger surface area as well as higher thermal stability compared to pure titanate nanotubes. The estimated magnetic moments point to presence of weak antiferromagnetic interaction. Application of the prepared Gd+3-TNT for modifying conventional photoanodes in polymer solar cells was attempted. Preliminary results show …

Current And Potential Distributions Of Three Non-Native Invasive Plants In The Contiguous Usa, Chad C. Jones, Sarah Reichard

Botany Faculty Publications

Biological invasions pose a serious threat to biodiversity, but monitoring for invasive species is time consuming and costly. Understanding where species have the potential to invade enables land managers to focus monitoring efforts. In this paper, we compared two simple types of models to predict the potential distributions of three non-native invasive plants (Geranium robertianum, Hedera spp., and Ilex aquifolium) in the contiguous USA. We developed models based on the climatic requirements of the species as reported in the literature (literature-based) and simple climate envelope models based on the climate where the species already occur (observation-based). We then compared the …

Remote Sensing Of Cropland Agriculture, M. Duane Nellis, Kevin P. Price, Donald Rundquist

School of Natural Resources: Faculty Publications

Remote sensing has long been used in monitoring and analyzing agricultural activities. Well prior to the first coining of the term ‘remote sensing’ in 1958 by Eveyln Pruitt of the U.S. Office of Naval Research (Estes and Jensen 1998), scientists were using aerial photography to complete soil and crop surveys associated with agricultural areas in the United States and other parts of the world (Goodman 1959). Most of such work in the 1930s involved general crop inventories by the U.S. Department of Agriculture and soil survey mapping as part of the work of the then U.S. Soil Conservation Service. With …

The Role Of Learning Styles In Student Evaluations Of A Problem-Based Learning Course, Larkin A. Powell

School of Natural Resources: Faculty Publications

I investigated the relationship between student learning styles and student evaluations of problem-based learning in a wildlife ecology and management course. I used two surveys for my inquiry: an on-line survey to determine student learning preferences, and an end-of-course survey of student reactions to problem-based learning (PBL). Forty-one students completed both surveys, and students’ learning preferences varied. I found significant relationships between learning preferences and student evaluation of PBL. Students with more active learning preferences found more value in the group learning experiences in my course. Group learning is often a critical component in problem-based learning courses, and my inquiry …

Documentation Of The Native American Ceramic Vessels From Northeastern Texas, Southern Arkansas, And Eastern Oklahoma In The Boyce Smith Museum In Troup, Texas, Timothy K. Perttula, Mark Walters, Bo Nelson

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

The Boyce Smith Museum opened in 1968 with the purpose of displaying a large collection of Historic artifacts as well as Native American artifacts collected and/or purchased over the years by Mr. Boyce Smith of Troup, Texas, now deceased. After learning of the museum in 2002, and taking a short visit to the museum at that time, it was apparent that the Boyce Smith Museum contained an important collection of Native American ceramic vessels that warranted documentation. With the permission of Jo Beth Smith, the wife of Boyce Smith, and their son Rial Smith, we returned to the Boyce Smith …

Prehistoric Artifact Assemblages From Sites Along Hickory Creek In The Davy Crockett National Forest, Houston County, Texas, Timothy K. Perttula, Bo Nelson

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

The National Forests and Grasslands (U.S.D.A. Forest Service) in Texas (NFGT) conducted Passports in Time (PIT) projects in 2006 and 2007 on Hickory Creek in the Davy Crockett National Forest, Houston County, Texas. The work—varying in extent—took place at four prehistoric archeological sites: 41HO13, HC-1, Hickory Creek #2 (HC-2), and HC-3, with the majority of the work occurring at HC-2.

We learned of the PIT projects at the sites in April 2007, when John Ippolitto, then Heritage Program Manager for the NFGT, mentioned the project to Perttula at the Annual Meeting of the Society for American Archaeology held in Austin, …

This report is the latest in a series of reports produced and published by the Caddo Nation of Oklahoma, Historic Preservation Program, that concern the documentation of funerary objects in museum facilities that are subject to the provisions and regulations of the Native American Graves Protection and Repatriation Act (NAGPRA). These documentation studies have been done either with grants from the National Park Service, or through funding provided by the museum facility. In the case of the present study of Caddo funerary objects in the collections at the Gilcrease Museum in Tulsa, Oklahoma, the documentation effort was supported by a …

Prehistoric Caddo Ceramics From The Henry Lake Site (41ce324), Cherokee County, Texas, Timothy K. Perttula, Tom Middlebrook

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

This article discusses the character of the Caddo ceramics from a single component Frankston phase (ca. A.D. 1400-1650) occupation at the Henry Lake site (41CE324) in northwestern Cherokee County, Texas. This follows a brief discussion of the history of the site, and we conclude this article with a consideration of the temporal and cultural place of the site's Caddo ceramic assemblage within the upper Neches River basin.

Prehistoric Ceramics From The Browning Site (41sm195a), Mark Walters

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

Archaeological work at the Browning site (4JSM195A) in eastern Smith County, Texas, has shown that it is a stratified site with two very distinct occupations: an early nineteenth century assemblage of artifacts in the upper zone overlying a buried prehistoric occupation. This occupation appears to be confined to the Woodland time period (ca. 500 B.C. to A.D. 800) with little evidence of any earlier or later prehistoric activity. The Woodland period in East Texas is a time of important cultural changes, "the most obvious (and most important?) of which is pottery-making and the bow and arrow."

The main focus of …

The Ceramics From A Late Caddo Site On Mud Creek In Cherokee County, Texas, Timothy K. Perttula

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

This article discusses the character of a large assemblage of prehistoric Caddo vessel sherds from a Late Caddo site (41CE309) on Mud Creek in Cherokee County, Texas, not far from the creek's confluence with the Angelina River. The site was discovered by Bill Young, an avocational archaeologist and Texas Archeological Steward, on a terrace of Mud Creek, just west of the city of Reklaw, Texas.

During the course of a number of visits to the site in the 1980s, more than 2300 ceramic sherds were collected by Young, most of the sherds being found in the central part of the …
