Using Multispectral Sensor Wasp-Lite To Analyze Harmful Algal Blooms, Shari J. Mcnamara Aug 2007

Using Multispectral Sensor Wasp-Lite To Analyze Harmful Algal Blooms, Shari J. Mcnamara

Theses

Developing methods to monitor harmful algae is a current research “hot-topic.” One type of algae, the blue-green algae or Cyanobacteria, cause blooms that can lead to a health threat to humans and animals. This research will test the use of a cost effective and temporally efficient method using multispectral remote sensing system, WASPLITE, as a monitor of algal blooms. This airborne system will be optimized to the specific application of detecting Cyanobacteria on optically complex waters. Attempts have been made in the past using existing instruments, e.g., SeaWiFS and Landsat, to provide these data, but our solution can provide more …

Investigating The Effects Of An On-Chip Pre-Classifier On Wireless Ecg Monitoring, Alexandru Samachisa Aug 2007

Investigating The Effects Of An On-Chip Pre-Classifier On Wireless Ecg Monitoring, Alexandru Samachisa

Theses

In past years, heart disease has been the leading cause of death in most developed countries. Timely detection of a heart condition is necessary in order to prevent life threatening situations. Even when the problem is not a heart condition, the activity of the heart can supply vital information, which makes its monitoring extremely important. A new approach to patient monitoring was taken recently by introducing wireless sensor networks into medical care. The capability of monitoring multiple patients at once makes such a system ideal for pre-hospital and in-hospital emergency care. The main problems associated with wireless sensor networks are …

Variation In The Abundance And Diversity Of Hymenoptera As An Indicator Of Biodiversity Across Three Tropical Habitats In Monteverde, Costa Rica, August 2007, Jessica Ramsel Aug 2007

Variation In The Abundance And Diversity Of Hymenoptera As An Indicator Of Biodiversity Across Three Tropical Habitats In Monteverde, Costa Rica, August 2007, Jessica Ramsel

Monteverde Institute: Tropical Ecology and Conservation

Loss of biodiversity is becoming increasingly evident and is receiving much attention. Fragmentation and conversion of natural forest into agricultural land in particular are increasingly detrimental to biodiversity. It has been stated that agroecosystems such as agroforestry provide a valuable contribution to the overall biodiversity of the landscape and may even be suitable for conservation efforts (Tylianakis et al. 2005; Klein et al. 2002). This study examined the relative abundance and diversity of Hymenoptera within three habitats: primary forest, an agricultural area, and an open area. This was done by placing yellow plates with honey and soap water in each …

Parallelization Of The Maximum Likelihood Approach To Phylogenetic Inference, Janine Garnham Aug 2007

Parallelization Of The Maximum Likelihood Approach To Phylogenetic Inference, Janine Garnham

Theses

Phylogenetic inference refers to the reconstruction of evolutionary relationships among various species, usually presented in the form of a tree. DNA sequences are most often used to determine these relationships. The results of phylogenetic inference have many important applications, including protein function determination, drug discovery, disease tracking and forensics. There are several popular computational methods used for phylogenetic inference, among them distance-based (i.e. neighbor joining), maximum parsimony, maximum likelihood, and Bayesian methods. This thesis focuses on the maximum likelihood method, which is regarded as one of the most accurate methods, with its computational demand being the main hindrance to its …

A Time-To-First-Spike Cmos Image Sensor, Xiaochuan Guo, Xin Qi, John G. Harris Aug 2007

A Time-To-First-Spike Cmos Image Sensor, Xiaochuan Guo, Xin Qi, John G. Harris

Electrical and Computer Engineering Faculty Research & Creative Works

A time-to-first spike (TTFS) imager was designed such that each pixel outputs a single digital pulse whose timing encodes pixel illumination. For still image applications, this time representation provides a tremendous increase in dynamic range, similar to that of other existing time-based imagers. However, a major advantage of the TTFS imager is that this wide dynamic range can be achieved even for 30 frames/s video applications. A prototype 32x32 TTFS image sensor was fabricated in AMI 0.5 μm CMOS technology. The prototype chip demonstrates a 104 dB dynamic range (limited by the optical equipment), 42 μV/electron conversion gain, 1.25 nA/cm …

Elastomer Degradation In Water Utility Systems Via Loss Of Carbon Black Observed With Atomic Force Microscopy., Randolph Norman Schoenbaechler 1972- Aug 2007

Elastomer Degradation In Water Utility Systems Via Loss Of Carbon Black Observed With Atomic Force Microscopy., Randolph Norman Schoenbaechler 1972-

Electronic Theses and Dissertations

The use of monochloramines in the potable water supply industry has been selected as the disinfectant method of choice due to a longer term of effectiveness and less toxic by-products than the previous choice of chlorine. In spite of the benefits exhibited by the use of monochloramines much greater rates of elastomer degradation have been noted in the water industry. The modes of attack by monochloramines on the rubber parts are still poorly understood. A common ingredient in nearly all elastomer formulations is carbon black. In addition to its role as a filler material, carbon black is also known to …

Impacts Of T-Phylloplanin Gene Knockdown And Of Helianthus And Datura Phylloplanins On Peronospora Tabacina Spore Germination And Disease Potential, Antoaneta B. Kroumova, Ryan W. Shepherd, George J. Wagner Aug 2007

Impacts Of T-Phylloplanin Gene Knockdown And Of Helianthus And Datura Phylloplanins On Peronospora Tabacina Spore Germination And Disease Potential, Antoaneta B. Kroumova, Ryan W. Shepherd, George J. Wagner

Plant and Soil Sciences Faculty Publications

T-phylloplanin proteins secreted to aerial surfaces of tobacco (Nicotiana tabacum) by short procumbent trichomes inhibit spore germination and blue mold disease caused by the oomycete pathogen Peronospora tabacina. Many other plants were found to contain water-washed leaf surface proteins (phylloplanins), but the functions and properties of these are not known. Here we extend earlier evidence for the antifungal activity of T-phylloplanins using a reverse genetics approach. RNA interference of the T-phylloplanin gene in tobacco ‘T.I. 1068’ resulted in loss of T-phylloplanin mRNA and protein, loss of in vitro spore germination inhibition activity, and leaf infection …

Book Review: Lisa Schirch. Ritual And Symbol In Peacebuilding, Janine Minkler Aug 2007

Book Review: Lisa Schirch. Ritual And Symbol In Peacebuilding, Janine Minkler

Genocide Studies and Prevention: An International Journal

A dancer stands before the Nazi gas chambers; in a moment of poised defiance, she glides up to the guard, seizes his gun, and shoots him. Lisa Schirch opens Ritual and Symbol in Peacebuilding with this story, dramatically illustrating one of her key points: through the act of ‘‘doing,’’ the doing becomes reality. ‘‘The dancer acts as if she is alive and powerful,’’ Schirch writes, ‘‘and through dancing, she becomes alive and powerful’’ (3). Traditional peacebuilding1 approaches tend to deal with issues directly, linearly, and rationally and, ironically, to reproduce adversarial space by placing conflicting parties in opposition to each …

Dishsoap For Clean Water: How The Design Of Everyday Objects Can Promote Happiness, Xanthe Matychak Aug 2007

Dishsoap For Clean Water: How The Design Of Everyday Objects Can Promote Happiness, Xanthe Matychak

Theses

This project began with the question: What keeps us from achieving sustainable happiness, happiness for ourselves and future generations? I have chosen to focus on the citizen/consumer conflict which occurs when our consumer choices are incongruous with our moral obligations to society. This conflict is a consequence of the market systems that are in place and consumers’ lack of a critical understanding of these systems. Thus, with this project, I am attempting to make these systems more transparent. Looking at economic approaches like price adjustment and awareness-raising strategies I have focused on the latter. Drawing from the history of semiotics …

What We Do Know About Rice (Oryza Sativa) Hemoglobins, Veronica Lira-Ruan, Emily H. Ross, Mark S. Hargrove, Gautam Sarath, Raul Arredondo-Peter, Robert V. Klucas

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Nonsymbiotic hemoglobins (nsHb) are proteins widely distributed in land plants, however their function in plant organs is still not known. Rice nsHbs have been characterized in detail and represent a model to study plant nsHbs. Rice recombinant Hb1 (rHb1) has a very high affinity for O2 (1,800 μM-1 s-1), because the dissociation constant is extremely low (koff = 0.038 s-1). X-ray analysis and site-directed mutagenesis showed that the low dissociation constant of rHb1 is partially due to the stabilization of bound O2 by distal His. This characteristic suggests that the function of …

The Evolution Of Color Polymorphism: Crypticity, Searching Images, And Apostatic Selection, Alan B. Bond Aug 2007

The Evolution Of Color Polymorphism: Crypticity, Searching Images, And Apostatic Selection, Alan B. Bond

School of Biological Sciences: Faculty Publications

The development and maintenance of color polymorphism in cryptic prey species is a source of enduring fascination, in part because it appears to result from selective processes operating across multiple levels of analysis, ranging from cognitive psychology to population ecology. Since the 1960s, prey species with diverse phenotypes have been viewed as the evolved reflection of the perceptual and cognitive characteristics of their predators. Because it is harder to search simultaneously for two or more cryptic prey types than to search for only one, visual predators should tend to focus on the most abundant forms and effectively overlook the others. …

False Promises: Females Spurn Cheating Males In A Field Cricket, William E. Wagner, Andrew R. Smith, Alexandra Basolo Aug 2007

False Promises: Females Spurn Cheating Males In A Field Cricket, William E. Wagner, Andrew R. Smith, Alexandra Basolo

School of Biological Sciences: Faculty Publications

Females commonly prefer to mate with males that provide greater material benefits, which they often select using correlated male signals. When females select higher-benefit males based on correlated signals, however, males can potentially deceive females by producing exaggerated signals of benefit quality. The handicap mechanism can prevent lower-quality males from producing exaggerated signals, but cannot prevent cheating by higher-quality males that choose to withhold the benefit, and this poses a major problem for the evolution of female choice based on direct benefits. In a field cricket, Gryllus lineaticeps, females receive seminal fluid products from males with preferred songs that …

A Systematic Approach To The Development Of Fluorescent Contrast Agents For Optical Imaging Of Mouse Cancer Models, Joy L. Kovar, Melanie A. Simpson, Amy Schutz-Geschwender, D. Michael Olive

Department of Biochemistry: Faculty Publications

In the past decade, our increased elucidation of the molecular basis of cancer has led to the development of novel targeted strategies for specific inhibition of cancer signaling pathways that control growth, proliferation, apoptosis, and angiogenesis. Several monoclonal-antibody-based therapeutics and small-molecule drugs have received clearance for use as human therapeutics [1]. However, among these successes are many candidate drugs that have failed in clinical trials despite promising preclinical results [2]. The development of targeted therapeutics is expensive and time consuming. In their Critical Path Initiative, the United States Food and Drug Administration emphasized the need for more effective tools to …
