Eastern Iowa Lithics And Their Effects On Oneota Culture, Caitlin Mary Kelly

Honors Program Theses

This research focuses on the experimentation and exploration of heat treatment used on chert by the Native Americans located in eastern Iowa after the Late-Woodland Period. In conjunction with my research advisor, Dr. Chad Heinzel, the geoarchaeologist in the UNI Department of Earth Science, I have heat treated chert from eastern Iowa in order to examine its physical and chemical changes. These experiments took place both in a controlled laboratory setting and in a semi-controlled field setting, comparing the difference between the two different methodologies. Chemical analysis was also performed to assess differences in trace chemicals between raw and heated …

Non-Destructive Dna Extraction Methods That Yield Dna Barcodes In Spiders, Reva Ann Bork

Honors Program Theses

DNA barcodes are short sequences of nucleotides that differ from species to species (Hebert et al., 2003; Hebert & Gregory, 2005). DNA barcoding is very important in helping to reconstruct phylogenetic trees and to confirm the identity of threatened or endangered species in the wild. Additionally, it has become increasingly popular in the food industry to test the accuracy of the food being sold in fast food chains (Wong and Hanner, 2008). For scientific purposes, nondestructive DNA extraction techniques need to be explored because they allow for preservation of the voucher specimen, which is particularly important for rare or extinct …

Relative Importance Of Phenotypic Trait Matching And Species' Abundances In Determining Plant - Avian Seed Dispersal Interactions In A Small Insular Community, Aaron González-Castro, Suann Yang, Manuel Nogales, Tomas A. Carlo

Biology

Network theory has provided a general way to understand mutualistic plant-animal interactions at the community level. However, the mechanisms responsible for interaction patterns remain controversial. In this study we use a combination of statistical models and probability matrices to evaluate the relative importance of species morphological and nutritional (phenotypic) traits and species abundance in determining interactions between fleshyfruited plants and birds that disperse their seeds. The models included variables associated with species abundance, a suite of variables associated with phenotypic traits (fruit diameter, bird bill width, fruit nutrient compounds), and the species identity of the avian disperser. Results show that …

The Synthesis And Characterization Of Dual-Modified Carboxymethylcellulose For Bioadhesive Applications, Fabrice Bernard

Dissertations and Theses

Reparative medical techniques, in conjunction with existing and emerging tissue adherents and sealants, offer practicing physicians a wide variety of tools to improve the functionality, performance, and safety of surgical interventions. Carboxymethylcellulose (CMC) is a plant-derived polymer that is cytocompatible, biocompatible, biodegradable, and inexpensive. The need for a non-toxic but strongly adherent material motivated the development of an injectable bioadhesive system containing CMC modified with functional methacrylate and aldehyde groups that could potentially be used as an annulus fibrosus sealant or as a supplement to existing wound closure materials. After modification, the polymer was characterized via NMR spectroscopy, Schiff’s base …

Effects Of Acetyl Salicyclic Acid On Drosophila Models Of Cancer-Inflammation, Roma Rajwani

Dissertations and Theses

Chronic inflammation is a fundamental condition underlying many human disease pathologies including diabetes, cancer, and neurodegeneration. Indeed, one of the most commonly-used anti-inflammatory drugs, aspirin, has been shown to be effective in the treatment of many cancers. To understand the mechanistic linkages between inflammation and cancer, we used Drosophila models in which hyperactive immune signaling causes overproliferation of the hematopoietic system leading to the production of inflammatory blood tumors. In mutant animals, hematopoietic cells divide uncontrollably and exhibit pre-mature differentiation giving rise to large sticky cells. Some mutant cells infiltrate and adhere to cells of the fat body. The fat …

Effects Of Temperature Stress On Coral Fluorescence And Reflectance, Andrea Gomez

Dissertations and Theses

Around the world, climate change, land-based pollution and fishing impacts are recognized as principal threats to coral reef ecosystems. Sea surface temperatures, in particular, are expected to change dramatically over the next decades and result in high coral mortality in some regions. Through controlled experiments, I examined changes in coral fluorescence and reflectance in response to water temperature alterations to assess the potential of employing these signatures as a diagnostic tool to measure coral health. At the NOAA Coral Culture and Collaborative Research Facility, I conducted controlled laboratory-based heat stress experiments on three Caribbean species of coral: Acropora cervicornis, Orbicella …

Development And Maintenance Of Thymic Epithelial Microenvironment, Varan J. Singh

Dissertations and Theses

Thymus is a primary lymphoid organ responsible for proper development and selection Of T-­‐cells. The thymic microenvironment, however, undergoes age related involution, Resulting in a reduction of the repertoire of T-­‐cells that are produced, and a decreased Capacity to respond to new antigen. Even though significant thymic epithelial turnover occurs, it is unclear if postnatal thymic progenitors/stem cell are responsible for the maintenance of the TEC microenvironment. Here we use the K5rtTA:TetO-­‐H2BGFP transgenic model to identify a slow cycling potential stem cells/progenitor population in the postnatal thymus. These cells were isolated, expanded in culture, and successfully differentiated into adipocytes, chondrocytes …

Food Imports As A Hindrance To Food Security And Sustainable Development: The Cases Of Nigeria And Senegal, Dioume Astou

Dissertations and Theses

Despite the growing global acceptance of an individual’s right to adequate food and nutrition, and the state’s obligation to ensure that all its citizens are free from hunger, 805 million or one in nine people around the world today are still chronically malnourished; the majority live in developing countries. African states have had a particular problem with food insecurity. Food security on the continent has worsened since the 1970s and by the end of the century, the population in Africa is

expected to be three times its current level. Hence, food insecurity in Africa will be much more severe than …

The Impact Of Forest Successional Status On Community Structure Of Neotropical Cerambycid Beetles, Lin Li

Dissertations and Theses

Due to anthropogenic activities, tropical rain forests face many challenges in sustaining biodiversity and maintaining global climates. This project examines how forest successional status affects community composition of saproxylic cerambycids, which, as early colonists of moribund trees, have an important role in nutrient cycling. In the lowland rain forest of Costa Rica, thirty-nine trees in five plant families (Fabaceae, Lecythidaceae, Malvaceae, Moraceae, and Sapotaceae) were sampled in a mosaic of old growth and secondary forest. They yielded 3545 cerambycid individuals in 49 species. Species richness was almost identical in old growth and secondary forest; but abundance was higher in old-growth. …

Rural Energy Development: Are Mini-Grids The Solution To East Africa's Energy Crisis, John Remson

Dissertations and Theses

As the population and economies of Sub Saharan Africa continue to grow, the demand for modern energy will correspondingly increase. The current energy policy and limited overall access rate is not prepared for this massive demand increases and presents a major hindrance to country growth potential. This thesis focuses on the countries in East Africa (Kenya, Tanzania, Ethiopia), and compares their current energy policies and renewable energy potential within a historical context of the United States rural electrification of 1930s. It is clear that some progress has been made in plans to address the energy access concerns but there is …
