Interview No. 1394, Félix Loera Carrillo Dec 2007

Interview No. 1394, Félix Loera Carrillo

Combined Interviews

Mr. Loera briefly describes his family and how they worked on an hacienda, but they did not live there; when he was seventeen years old, he came to the United States to work, without documents, in the hope of having a better life; after two years, he returned to México and shortly thereafter married; by the late fifties, he and his wife had two children and were struggling to make ends meet, which led to his decision to enlist in the bracero program; although most men had to pay to get on the list of available workers, he knew someone …

Figuring The Digital, Molly Morin Dec 2007

Figuring The Digital, Molly Morin

All Theses

This body of work is a way of understanding, reflecting on, and contributing to a contemporary dialogue about the impact of digital technology and the Internet on society by looking at the organization of information that lies behind the computer screen, and creating work that is sourced directly from the Internet but becomes a tangible object in the physical world. I use methods of mass production and marketing to create artwork that values individuality over homogenization and complexity over efficiency, co-opting practical digital technology for the purposes of physical beauty. The work should inspire a sense of wonder through its …

Fungal Conversion And Supercritical Carbon Dioxide Processing For Value-Added Canola Oil, Meidui Dong Dec 2007

Fungal Conversion And Supercritical Carbon Dioxide Processing For Value-Added Canola Oil, Meidui Dong

All Dissertations

There is a growing awareness of health benefits of polyunsaturated fatty acids (PUFAs) e.g. arachidonic acid (ARA, C20:4n6) and eicosapentaenoic acid (EPA, C20:5n3). In general, plant seed oil and animal fat do not contains long-chain PUFAs with more than eighteen carbons. This study investigated the feasibility for addition of ARA and EPA to canola oil through the fermentation of fungi, Mortierella alpina, using canola flake, cake or meal as substrates. Supercritical CO2 extraction was also investigated for lipid extraction. In addition, a supercritical CO2 explosion process was characterized and applied to enhance oil extraction using supercritical CO2 and to potentially …

Development Of An In Vitro Test System For Breast Cancer Research, Chih-Chao Yang Dec 2007

Development Of An In Vitro Test System For Breast Cancer Research, Chih-Chao Yang

All Dissertations

In the United States, breast cancer is the third most common cause of cancer death (after lung cancer and colon cancer). In 2007, breast cancer is expected to cause 40,910 deaths (7% of cancer deaths; almost 2% of all deaths) in the U.S. The long term goal of this project is to develop an in vitro test system that can be used to develop breast cancer vaccine or screen breast cancer chemotherapy. This dissertation was driven by four objectives and it can be thought as a toolbox that provides practical experimental design and lab work for the development of an …

The Diffusion Of The Reggio Emilia Approach Among Early Childhood Teacher Educators In South Carolina, Julie Hartman Dec 2007

The Diffusion Of The Reggio Emilia Approach Among Early Childhood Teacher Educators In South Carolina, Julie Hartman

All Dissertations

Growing numbers of U.S. educators are traveling to the northern Italian town of Reggio Emilia to study the innovative, arts-based approach to early education developed in the town's municipal infant-toddler and pre-primary programs now commonly referred to as the Reggio Emilia Approach. And though there is no way of knowing exactly how many educators and early childhood programs across the U.S. are currently making use of the approach, increasing numbers of U.S. colleges and universities are including the approach in both their ECE teacher preparation as well as campus child development programs, suggesting the Reggio Emilia Approach (REA) is diffusing …

Enhancing The Ability Of Panicum Virgatum To Survive Flooding And Its Effects On Soil Activity When Used For Lakeshore Stabilization, Lee Edwards Dec 2007

Enhancing The Ability Of Panicum Virgatum To Survive Flooding And Its Effects On Soil Activity When Used For Lakeshore Stabilization, Lee Edwards

All Dissertations

Reservoirs in upstate South Carolina are subject to erosion and vegetation has been placed to help stabilize banks, but soils are nutrient-poor and have high bulk densities. Panicum virgatum L. (switchgrass) has been planted in several sites, and it is hypothesized that over time, changes in microbial activity and soil quality will occur in response to the planting. As vegetated sites aged, acid phosphomonoesterase, nitrate reductase, and dehydrogenase activity increased. Low values of nitrogen fixation and substrate-induced respiration were measured at all sites with no statistical differences between sites. Fatty acids indicative of Gram negative bacteria were found in vegetated …

The Consumer Choice Of E-Channels As A Purchasing Avenue: An Investigation Of The Communicative Aspects Of Information Qualtiy , Jaejoo Lim Dec 2007

The Consumer Choice Of E-Channels As A Purchasing Avenue: An Investigation Of The Communicative Aspects Of Information Qualtiy , Jaejoo Lim

All Dissertations

A conspicuous paradox is evident in the statistics concerning purchases over the internet. While a majority of the US population uses the internet to seek product information for purchasing decisions, less than two percent of actual retail sales occur on the Internet. To explain this small ratio of e-channel choice for purchase, a comprehensive model that extends DeLone and McLean's (2004) e-commerce success model was developed. The model centers on the importance of perceived information quality and its relationship to e-channel choice as a purchasing channel. Using the overarching theoretical frame of motivation, two questions were examined: (a) what influences …

Ultrahydrophobic Surface Modification Of Polymeric Fibers And Inorganic Substrates, Karthik Ramaratnam Dec 2007

Ultrahydrophobic Surface Modification Of Polymeric Fibers And Inorganic Substrates, Karthik Ramaratnam

All Dissertations

The wettability of a solid surface is a very important property, and is governed by both the chemical composition and the geometrical microstructure of the surface. Wettability and repellency are important properties of solid surfaces from both fundamental and practical aspects. The wettability of the solid surface is a characteristic property of materials and strongly depends on both the surface energy and the surface roughness. These properties may be approached by mimicking hydrophobic structures created by nature on lotus leaf surface. The lotus effect is based on surface roughness caused by different microstructures together with the hydrophobic properties of the …

Lithium-Conducting Ionic Melt Electrolytes From Oligomeric Ethylene Glycols: Synthesis And Characterization, Boutros Hallac Dec 2007

Lithium-Conducting Ionic Melt Electrolytes From Oligomeric Ethylene Glycols: Synthesis And Characterization, Boutros Hallac

All Dissertations

Commercial lithium ion cells consist of electrolytes that undergo salt concentration polarization which is acute upon high discharge currents. This type of polarization occurs as a result of the mobility of more than one ionic species in the presence of an electric field. One way to overcome it is by employing a material that would allow the mobility of one ionic species. This thesis will describe the synthesis and characterization of several fluorosulfonimide and fluorosulfonate based ionic liquids/melts as electrolytes having lithium as the only mobile ion. These materials were prepared by the nucleophilic addition reaction of a deprotonated polyether …

Nesting And Foraging Characteristics Of The Black Carpenter Ant Camponotus Pennsylvanicus (Degeer) (Hymenoptera: Formicidae), Donald Oswalt Dec 2007

Nesting And Foraging Characteristics Of The Black Carpenter Ant Camponotus Pennsylvanicus (Degeer) (Hymenoptera: Formicidae), Donald Oswalt

All Dissertations

Potential nesting sites of Camponotus pennsylvanicus (DeGeer) were investigated in South Carolina to determine if nesting sites features could be characterized by habitat features for black carpenter ant nests. Environmental data from forested plots showed large-scale habitat features such as vegetation density and canopy cover were not useful as indicators for the presence or absence of nests. Small-scale individual nest characteristics such as diameter at breast height of trees, log length, tree defect type or tree species were better indicators of occupied nests. In my study, C. pennsylvanicus preferred mature hardwood (Quercus spp.) trees approximately 30 cm in diameter and …

The Lss Supernodulation Mutant In Medicago Truncatula: Genetics, Characterization And Mapping, Arijit Mukherjee Dec 2007

The Lss Supernodulation Mutant In Medicago Truncatula: Genetics, Characterization And Mapping, Arijit Mukherjee

All Dissertations

The symbiotic association between legumes and nitrogen fixing rhizobia culminates in the formation of root nodules. Legumes control the extent of root nodule formation through a regulatory mechanism in which nodulating roots induce a shoot response that signals back to the roots, inhibiting further nodule initiation. Disruption of genes involved in this regulatory process lead to super or hypernodulation. The lss (like sunn supernodulator) mutant of Medicago truncatula has been identified as a naturally occurring supernodulation mutation in the Jemalong cultivar. The phenotype of lss is practically indistinguishable from the phenotype of the previously isolated sunn mutant with respect to …

Studies In The Biochemistry And Cell Biology Of Trypanosoma Brucei Hexokinases, Jeremy Chambers Dec 2007

Studies In The Biochemistry And Cell Biology Of Trypanosoma Brucei Hexokinases, Jeremy Chambers

All Dissertations

Trypanosoma brucei expresses two hexokinases (TbHK1 and TbHK2) that are 98% identical at the amino acid level. We previously found that recombinant TbHK1 (rTbHK1) has hexokinase activity, while rTbHK2 did not, a finding attributed to differences in the C-termini of the proteins. We found that the C-terminal tails of TbHK contained a novel motif specific for eukaryotic hexokinases found within the final helix of an ATP-binding domain. By altering the residues in the C-terminal tail of TbHK1 to resemble the residues found in TbHK2, we found that D454, F462, M466, and N469 were essential to TbHK1 catalysis. Additionally, we found …
