The Effects of Color Concentrate in Polyolefins.

Access: Use of this item is restricted to the UNT Community
Throughout history consumer products were generally manufactured from wood and metal. They either had to hold their natural color or become subject to painting. When plastics entered the industry, it was recognized for its ease of shaping, re-usability, physical properties and its low cost. One of plastics' greatest benefits is its ability to hold a given color from within allowing it to avoid use of paint. This paper will give a brief overview on the effects of pigments when incorporated in a polyolefin. It will provide a classification of the main types of pigments and how each effect the properties of the product through: crystallization, weatherability, opacity, coloristic values and of course viscosity.

Microwave Cavity Test for Superconductivity

Access: Use of this item is restricted to the UNT Community
The first part of this paper describes the Meissner effect in superconductors which serves as the most definitive evidence for superconductivity. It is shown that the microwave perturbation technique may be used to demonstrate this effect. By measuring the changes of resonant frequency and inverse quality factor Q of a microwave cavity with a small volume of sample loading, the Meissner effect can be shown by using the Slater perturbation equation. The experimental system is described with details and the basic principle of each component discussed. The second part of this work describes the technique employed to do the actual measurements. The experiments were conducted on samples of Gallium Arsenide (GaAs) and lead zirconate titanate (PZT) to look for the possible high temperature superconductivity properties. Results of these experiments are presented and discussed. Conclusion and suggestions to future exploration are made.

Die Neue Lehre: Developing an Online Course in Schenkerian Analysis

Access: Use of this item is restricted to the UNT Community
With the proliferation of Schenkerian theory in the US, Great Britain, and mainland Europe in the past quarter century, the pedagogy of Schenkerian analysis has become an important issue. Schenker himself was suspicious of textbooks with their tendency for artificial codification and over-simplification; rather, he recognized that his “New Teaching” (“Die neue Lehre”) – as he called it – required a different, more “organic” pedagogical approach that was both personal and yet accessible to a wide audience. New digital technologies and the Internet now have made it possible to disseminate Schenker’s pedagogical approach by adapting interactive techniques of Web-based instruction. Schenker’s “new teaching” was as organic as his theory itself – and as novel in the connections it sought to draw between the individualed disciplines of theory, musicology, composition, and performance. The interactive and multi-media components of Web-based instruction enable us to realize Schenker’s own pedagogical approach to Schenkerian analysis instruction.

Process, Form, and Function

Access: Use of this item is restricted to the UNT Community
Process and form have always been important to my work. I emphasize the soft qualities of clay while working with traditional forms that are altered for visual interest. Usability is very important, the forms have to function well according to their intended use. The relationship between form and manipulation relied on usability of the form. Functionality was paramount within this body of work. I consciously searched for balance between form and manipulation, form and glaze, form and function, and overall character. Though altered, the forms were traditional and dependent on function. Manipulations of the forms, surface treatment, and deep colorful glazes contributed to creating harmony between function and expression. Personal stylistic elements became refined through working on this project. The body of work that was made allocated personal expression and new variations on functional forms. This project provided an opportunity for exploration and evaluation of form and my working process.

Animal Contribution to Human Medicine

Access: Use of this item is restricted to the UNT Community
The use of animal models in research has led to a fierce debate between animal rights activists and scientists. The former claim that little useful information is gained from animal studies and the suffering of animals does not preclude any treatments which may be used to treat human illnesses. Yet, research scientists claim that in vivo animal models are of absolute necessity to developing treatments and cures to disease. To determine the necessity of animal use, one must examine the models currently in research. Have the animal models for disorders such as cystic fibrosis and muscular dystrophy given scientists enough information to develop effective treatments? This paper will examine the role of animal subjects in several disease research protocols, as well as the applicability of the research.

Inherent Problems Associated with the Identification of Genes Responsible for Allowing B. cepacia to Adhere to Human Lung Carcinoma A549 Cells

Access: Use of this item is restricted to the UNT Community
In this project a bacteria's ability to bind to human lung tissue was investigated. To carry out this study Pseudomonas aeruginosa, Eschericia coli and Burkholderia cepacia were used. B. cepacia served as the bacterium of interest. Isolating the gene which confers upon this bacterium the ability to bind to lung tissue was the main objective of this study. P. aeruginosa has been identified as being the bacteria most responsible for causing serious lung infections that can result in cystic fibrosis. This bacterium therefore served as the positive control in this study. On the contrary, E. coli does not possess this binding ability and served as the negative control. This paper gives a detailed outline of the different procedures necessary for the successful completion of this project. Firstly, a broad guideline of the important steps involved are explored. This is followed by a discussion on potential problems and possible solutions. Throughout the document, illustrations of expected results are indicated so as to further guide the researcher.

Mis Raices, Mi Hogar: My Roots, My Home

Access: Use of this item is restricted to the UNT Community
The lack of ancestral record instilled in me this desire to hold on to memories, and to leave my children with permanent records or memories of our family. My desire to work with metals was inspired by the need to encapsulate a record of memories through a more permanent means. The durability of steel, I feel, can be used as a diary, in the form of an artistic and lasting object, rather than written words. The need to leave behind a legacy inspired me to explore the use of lockets and containers that have some resemblance to a reliquary. My intent was not one of religious purpose, but rather to create a locket or container that would reflect or contain symbols of where one's roots begin, the home.

Resident Care Policies in an Administrative Policy Manual for Texas Long-Term Care Facilities

Access: Use of this item is restricted to the UNT Community
Federal and state regulations require that licensed long-term care facilities have policies for every resident-related topic. Long-term care administrators must plan, implement, and evaluate resident care policies that can be easily personalized to the needs of the specific facility's population. Part 1 of this paper is an overview of resident policies, covering admission, physician services, transfers and discharges, nursing services, restraints, abuse and neglect, pharmaceutical services, dietary services, clinical records, therapeutic recreation services, and social services. Part 2 presents the policies themselves, ready for use by Texas long-term care administrators as part of their facility's administrative policy manual.

Round

Access: Use of this item is restricted to the UNT Community
My approach to the art making process is a kind of poetic reverie on forms and spaces. Webster’s Encyclopedic Unabridged Dictionary defines reverie as “a state of dreamy meditation or fanciful musing; a daydream, a fantastic, visionary or unpractical idea.” It is a romantic notion that has less to do with the big questions of existence than it does the incidental parts of daily existence. Reverie is a state of mind that comes from being receptive and finding simple pleasure in the affects of imagination. My paintings, drawings and sculpture evolve out of the freedom to imagine shapes and spaces that describe different kinds of interactions. They come from recollection, awareness, and observation of the diverse sensual phenomena that surrounds me. The variety of interactions between forms such as contrast, imbalance, balance or synchronicity, have the potential to evoke various aspects of being: vulnerability, uncertainty, confidence, and determination. Possible interactions between shapes and spaces are what intrigue me most. Recently, I expanded the investigation of form to include objects and consideration of space. As the scale of my paintings and drawings grew, I became interested in the effects of three-dimensional objects in a space, such as a gallery. My inquiry …
