Use Of Rapds To Develop Specific Primers For The Identification Of Mycorrhizal Fungi, Cynthia A. Boyd

Dissertations and Theses @ UNI

The restoration of damaged ecosystems, particularly at superfund sites is a complex issue. These sites present problems with revegetation attempts due to their unique chemical, physical, and biological properties. Revegetation of damaged ecosystems may be enhanced by mycorrhizal associations. The establishment of a facultative mycotroph, Festuca arundinacea Screb. (tall fescue) treated with a commercial fungal inoculum, was studied at a Galena, Kansas mining site. The evaluation of this revegetation project required the identification of endomycorrhizal fungi, Glomus c/arum and G/omus etunicatum in the inoculum. Traditional identification of these fungi based on spore morphology and other physical characteristics is not suitable …

The Relationship Between Coping Strategies And Body Image Among Adolescent Females, Lisa Monae Yarrow

Dissertations and Theses @ UNI

The purpose of this study was to investigate the relationship between coping strategies and body image disturbance among adolescent females. Fifty-eight of 78 (74.4%) seventh grade female students at a midwestern middle school completed all phases of the research.

The Eating Attitudes Test (EAT-26; Gamer & Garfinkel, 1979) identified subjects with maladaptive eating behaviors. The Coping Inventory for Stressful Situations (CISS; Endler & Parker, 1990) and the Body Shape Questionnaire (BSQ; Cooper, Taylor, Cooper, & Fairburn, 1987) provided information concerning the type of coping strategies employed as well as feelings concerning appearance.

Pearson product-moment correlation was used to determine the …

Differential Expression Of The Putative Multidrug Resistance (Mdr) P-Glycoprotein In Marine Hepatocytes, Marty C. Braud

Dissertations and Theses @ UNI

Aquatic organisms such as fish, sponges and mussels are exposed to mixtures of chemicals in polluted waters including polycyclic aromatic hydrocarbons, pesticides and heavy metals. The tissues of some of these organisms are found to have a lower concentration of pollutants compared to the surrounding waters and/ or sediments. This suggests that some aquatic organisms may possess a means of detoxifying environmental pollutants. For this study, primary hepatocytes of the marine winter flounder (Pleuronectes americanus) and freshwater rainbow trout (Salmo gairdnen) hepatomas were exposed to environmental pollutants to determine whether a multidrug-resistance (MDR) p-glycoprotein (pgp) extrusion pump is involved in …

Low-Cost Videoconferencing For The Clinical Management Of Speech & Language Disorders, Dale Lee Burgess

Dissertations and Theses @ UNI

Videoconferencing allows participants separated by distance to see and hear each other in real time. Traditionally, videoconferencing has been associated with expensive, room-based systems that limit the number of potential users. Recent advances in technology have made it possible to videoconference via desktop computers using inexpensive software programs. This has allowed broader participation in videoconferencing, thus, making it a more affordable means of communication. The purpose of this study was to determine if desktop videoconferencing (DVC) could be used in the clinical management of individuals with communication disorders. One of the potential advantages of DVC over traditional therapy programs is …

Typographic Communication, Soo-Kyung Chun

Dissertations and Theses @ UNI

The main influence on my graduate work has been the art of my native country of South Korea. A predominant feature of oriental paintings is black ink. I have always been intrigued by the balance of black and white elements which I associate with figure- and- ground in Western design theory. This intrigue has continued as my education has broadened into the field of graphic design. The opportunity to combine artistic intuition with technical computer- based media prompted me to study graphic design at the University of Northern Iowa beginning in 1996. It was my ambition to study a diversity …

Gangs, Drugs, And Delinquency, Tina Renea Engstrom

Dissertations and Theses @ UNI

The main objective of this thesis is to study the link between gangs, drug use, and delinquency. Previous literature suggests that social learning and social control theories commonly provide theoretical contexts for explaining deviant behavior. The present research applies the principles of Sutherland's (1949) theory of differential association and Hirschi' s (1969) theory of social control to the delinquent behavior of gang members and their drug involvement. The present study does not attempt to explain why youths become gang members. Rather, this research uses an integration of social learning and social control theories to explain why gang members become involved …

Organically Deposited Metallic Films For Device Fabrication, Thomas J. O'Keefe, M. Stroder, Matthew O'Keefe

Materials Science and Engineering Faculty Research & Creative Works

Advances in integrated circuit density, speed and complexity are dependent on lower resistance, finer line width on-chip interconnections. Methods for incorporating copper interconnects into IC fabrication processes have been developed which accomplish this objective but most of these methods use some form of blanket metal deposition that requires mechanical and/or chemical removal of excess material. To date, investigations into the selective deposition of conductor materials for device fabrication have met with limited success. A new process for selectively depositing metallic conductors using inexpensive, organic-based chemical solutions could potentially force a paradigm shift in the deposition of metals for microelectronic applications. …

Genetic Characterization Of The Gene Coding For A 77 Kd Ascospore-Specific Protein In Aspergillus Nidulans, Chad Edward Galer

Dissertations and Theses @ UNI

This study is one of the first molecular characterizations of a gene whose expression is exclusive to ascospores of Aspergillus nidulans. A 900 base pair (bp) fragment of this gene was cloned into a modified pUC19 plasmid and used to transform uridine auxotrophs of A. nidulans. Previous studies showed that A. nidulans is amenable to DNA mediated transformation by site-specific recombination (Fincham , 1989). Transformants were severely deficient in the production of ascospores, with decreases in viable ascospores per cleistothecia of 80-99.75%. Southern blotting experiments confirmed that integrative homologous transformation occurred in all cases, and that a tandem insertion is …

The Morality Issue: How Darlan Influenced The Allied Unconditional Surrender Pledge In World War Ii, Brian Fiderlein

Dissertations and Theses @ UNI

When World war II began in September 1939, polls indicated that most Americans believed it did not pose a threat to the United States and opposed any involvement by a ratio of 27-to-1.

President Franklin Roosevelt perceived that the power of Nazi Germany and its ideals posed a threat to American democracy. He presented the war to the American public as a moral struggle as well as one for security. The President publicized this view most notably in his Four Freedoms speech and in the Atlantic Charter. Both statements defined the moral goals of basic human freedoms and national self-determination. …

Evaluation Of Revegetation Techniques Used On Degraded Agricultural Land In The Central Avon Catchment, Western Australia, Scott J. Bartholomew

Theses: Doctorates and Masters

The agricultural region in the central Avon catchment is declining in both arable land and native vegetation. This decline has been due to the clearance of large tracts of native vegetation and its subsequent replacement by exotic crops and pasture species. The loss of vegetation has led to regional land degradation in the form of soil erosion and land salinisation. Therefore, changes in land management practices are required to make agricultural production more compatible with land conservation. Revegetation using native plants is the only management solution that integrates both land and ecological conservation with agricultural productivity. The continuation of current …

Redefining The Art Experience : From Static To Temporal Art Forms, Justine Mcknight

Theses: Doctorates and Masters

This research examines an approach to art making and viewing that questions the acceptance of the autonomous object in favour of a transient experience. It focuses specifically on work and writing from the 1960s by the American artist Robert Morris that attempted to alter the then predominant Formalist understanding of the art object as autonomous and self-referential. This investigation follows the formal and conceptual development of Morris' work (and that of associated artists Richard Serra and Rafael Ferrer) with particular focus on the shift from static objects to time-based and transient an-forms including film/video and installation. I address the influence …

The In Vitro Propagation Of Seagrasses : Halophila Ovalis, Ruppia Megacarpa And Posidonia Coriacea, Melissa Grace Henry

Theses : Honours

Seagrass communities are of high ecological and economic significance. They provide a nursery area for commercial and recreational juvenile fish and crustacea. Seagrasses also play an important role in influencing the structure and function of many estuarine and nearshore marine environments. Unfortunately, the decline of seagrasses, as a result of human impact, has increased in recent years. This decline has become a major problem throughout the world. Current methods used to restore degraded seagrass beds are limited, the most promising being transplanting material from healthy donor beds. This approach is expensive because it is labor intensive and damages the donor …
