Effect Of Crust Freezing On The Quality And Survival Of Escherichia Coli And Salmonella Typhimurium In Raw Poultry Products, Byron Chaves-Elizondo

All Theses

Industry has widely used freezing as a strategy to halt pathogen growth and more recently, crust freezing has been suggested as a means to improve mechanical operations, quality, and safety of poultry products. Two separate studies were conducted to evaluate the effect of crust freezing (20 min, -85 ¡C) on the survival of Escherichia coli and Salmonella Typhimurium and on quality and shelf life of raw chicken breasts, with or without skin. For the first study, ampicillin-resistant E. coli JM 109 and nalidixic acid-resistant S. Typhimurium were used in the experiments. A set of cultures was subjected to cold-shock stress …

Identification Of Patterns And Controls Of The Distribution Of Groundwater Discharge To Streams, Curtis Gebhard

All Theses

Groundwater discharge is a key component in understanding the interaction between groundwater and surface water. It provides baseflow to streams and can transport nutrients and contaminants to related aquatic ecosystems. It can also influence fish behaviour, spawning, migration and provide areas of refuge during summer and winter months. There are a variety of techniques that are used to characterize the magnitude of groundwater discharge including seepage meters, field permeameters, and piezometers and manometers, however the controls for the magnitude and distribution of discharge remain poorly understood. The purpose of this study was to conduct field investigations complimented with numerical analysis …

Evaluation Of Tetrachloroethene Dechlorination Under Low Ph Conditions In Microcosms And Enrichment Cultures, Michael Hickey

All Theses

Chlorinated ethenes are among the most prevalent groundwater contaminants found at hazardous waste sites throughout the United States. Two such sites are the Statesville FCX OU3 Superfund Site in North Carolina and the C-area at the Savannah River Site (SRS) in Aiken, SC. Both sites are contaminated with two of the more common chlorinated ethenes; tetrachloroethene (PCE) and trichloroethene (TCE). Anaerobic biological reductive dechlorination is an increasingly common treatment option. There are two main concerns as to the feasibility of this approach. The first is if the microbes are present that are needed for carrying out complete reductive dechlorination of …

Residential Landscape Water Check Programs: Exploring A Conservation Tool, Diana T. Glenn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In response to drought and regional growth in the arid western United States, urban water demand management is increasingly important. Single family residences use approximately 60% of their water consumption to irrigate landscapes often in excess of plant water requirements. This study utilized a quasi-experimental design to investigate outdoor water consumption and assess the effectiveness of a landscape water check conservation program. Study objectives included describing a contextualized landscape system to reveal variables influencing water use, identifying better ways to evaluate landscape water use, and more effectively targeting and delivering water conservation programs.

The study was conducted during the 2004 …

Olfactory Mate Choice And Potential Chemical Signals Of The White-Throated Sparrow (Zonotrichia Albicollis), Peter Sebastian

All-Inclusive List of Electronic Theses and Dissertations

Chemical odor signals are well documented in mammals, and yet almost nothing is known about the use of chemical odor signals in birds due to the traditional view that birds have a no sense or a poor sense of smell. Recent studies have revealed the traditional view to be unfounded, but more work is necessary to 1) expand our knowledge of avian olfaction in passerine species and 2) determine whether birds utilize chemical signals. The aim of this thesis was to 1) test for olfactory-based choice in a passerine species, and examine the chemical composition of preen oil for potential …

Large Group Delay In A Microwave Metamaterial Analog Of Electromagnetically Induced Transparency, Lei Zhang, Philippe Tassin, Thomas Koschny, Cihan Kurter, Steven M. Anlage, C. M. Soukoulis

Physics Faculty Research & Creative Works

We report on our experimental work concerning a planar metamaterial exhibiting classical electromagnetically induced transparency (EIT). Using a structure with two mirrored split-ring resonators as the dark element and a cut wire as the radiative element, we demonstrate that an EIT-like resonance can be achieved without breaking the symmetry of the structure. The mirror symmetry of the metamaterial's structural element results in a selection rule inhibiting magnetic dipole radiation for the dark element, and the increased quality factor leads to low absorption (<10%) and large group index (of the order of 30).

Promises To Keep: Diplomatic Assurances Against Torture In Us Terrorism Transfers, Human Rights Institute

Human Rights Institute

“Diplomatic assurances” are promises not to torture. They are sought when transferring a detainee from the custody of one government to another. Not surprisingly, they are sought from governments that typically torture.

This report surveys the law and practice of assurances in the US and, comparatively, in Canada and Europe. It is the culmination of a long-term engagement by Columbia’s Human Rights Clinic and its faculty to research and support advocacy on diplomatic assurances. That process has involved advocacy with Swedish NGOs, support for research by Human Rights Watch, FOIA requests with the ACLU and collaborative efforts with UN mechanisms. …

The Colour That Remains, Wai Yi, Monti Lai

Artists-in-Residence Programme : Exhibition Catalogues

A Residency Project by Lai Wai-Yi, Monti

Close your eyes, and try to see the colour in your mind. Would that be white, yellow, orange, red, blue, purple, green or a mix of different colour? Green has been the colour that remains in my head whenever my eyes are closed, ever since I received a homemade herbal poultice after an accident at the age of 6. I was bitten by a dog at my aunt’s home. It was a sunny winter day. I was wearing my favorite yellow furry coat. I was patting the dog’s forehead and talking to her. …

The Unwise And Unconstitutional Hatch Act: Why State And Local Government Employees Should Be Free To Run For Public Office., Jason C. Miller

Southern Illinois University Law Journal

This article examines the restrictions instated by the Hatch Act, a statute that prevents federal, state, and local employees from using their position or authority to influence elections. It also prohibits the candidacy for office for some government employees. While the author criticizes the restrictions imposed by the Act, there is support for the Act’s protections against coercion and inappropriate use of federal funds. The article analyzes the nuances of the Hatch Act and discusses perceivably negative effects of the Act on the political process, including the automatic disqualification of ideal candidates and a more restricted selection of candidates generally. …

Regulation Of Claudin-1 Expression Via Activation Of Ron Tyrosine Kinase And Transforming Growth Factor-Beta Signaling Pathways In Ovarian Carcinoma, Saya Karim

Honors Thesis and Capstone Projects

Epithelial ovarian carcinoma is the most common cause of death among gynecologic malignancies in the United States. In the U.S., more than 21,000 women will be diagnosed with ovarian cancer and about 15,000 women will die of the disease this year alone. Although migration and invasion play key roles in tumor progression, the specific molecular events leading to dissemination of ovarian tumor cells have not been well delineated. Tight junctions are an integral component of epithelial junction complexes, which play a vital role in maintaining epithelial integrity and cell polarity. Disruption of tight junctions is a hallmark of epithelial cancer …

Advertising In Online Social Networks: A Comprehensive Overview, Silvia Stockman

Honors Scholar Theses

This paper examines characteristics of online social networking sites and their implications on advertising. The application of well known interpersonal and mass communication theories to the field allows for an in-depth look at behavioral cues and responses. The interactivity inherent in sites like Facebook, MySpace, YouTube, and in other forums encourages advertisers to tap into engaging their consumers. Types of targeting and the success of word of mouth referrals are examined, as are many of the common stumbling blocks. To better understand the potential versus the problems, we conclude with an analysis of return on investment.

Curbing Energy Sprawl With Microgrids, Sara C. Bronin

Cornell Law Faculty Publications

Energy sprawl - the phenomenon of ever-increasing consumption of land, particularly in rural areas, required to site energy generation facilities - is a real and growing problem. Over the next twenty years, at least sixty-seven million acres of land will have been developed for energy projects, destroying wildlife habitats and fragmenting landscapes. According to one influential report, even renewable energy projects - especially large-scale projects that require large-scale transmission and distribution infrastructure - contribute to energy sprawl. This Article does not aim to stop large-scale renewable energy projects or even argue that policymakers focus solely on land use in determining …

Identification Of Holocarboxylase Synthetase Chromatin Binding Sites In Human Mammary Cell Lines Using The Damid Technology, Dipika Singh

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Holocarboxylase synthetase (HCS) is a chromatin protein that is essential for mediating the covalent binding of biotin to histones. Biotinylation of histones plays crucial roles in the repression of genes and repeats in the human genome. The objective of this project was to determine genomic binding sites of holocarboxylase synthetase (HCS) in the human chromatin of breast cell lines using an antibody independent technology. We tested the feasibility of DNA adenine methyltransferase identification (DamID) technology to map HCS binding sites in human mammary cell lines. Full-length HCS was fused to Dam for subsequent transfection into breast cancer (MCF-7) and normal …
