Absence Of All Components Of The Flagellar Export And Synthesis Machinery Differentially Alters Virulence Of Salmonella Enterica Serovar Typhimurium In Models Of Typhoid Fever, Survival In Macrophages, Tissue Culture Invasiveness, And Calf Enterocolitis, Clare K. Schmitt, Jack S. Ikeda, Stephen C. Darnell, Patricia R. Watson, Jennifer Bispham, Timothy S. Wallis, Debra L. Weinstein, Eleanor S. Metcalf, Alison D. O'Brien

Uniformed Services University of the Health Sciences

In this study, we constructed an flhD (the master flagellar regulator gene) mutant of Salmonella enterica serovar Typhimurium and compared the virulence of the strain to that of the wild-type strain in a series of assays that included the mouse model of typhoid fever, the mouse macrophage survival assay, an intestinal epithelial cell adherence and invasion assay, and the calf model of enterocolitis. We found that the flhD mutant was more virulent than its parent in the mouse and displayed slightly faster net growth between 4 and 24 h of infection in mouse macrophages. Conversely, the flhD mutant exhibited diminished …

Citizen Knowledge And Perception Of Black-Tailed Prairie Dog Management, Natalie R. Sexton, Ayeisha Brinson, Phadrea D. Ponds, Kurt Cline, Berton L. Lamb Jan 2001

Citizen Knowledge And Perception Of Black-Tailed Prairie Dog Management, Natalie R. Sexton, Ayeisha Brinson, Phadrea D. Ponds, Kurt Cline, Berton L. Lamb

United States Geological Survey: Publications

What do citizens know about black-tailed prairie dogs, and where do they get their information? When management decisions need to be made regarding an animal such as the black-tailed prairie dog, an understanding of the species and its relationship to humans is necessary. This includes knowing the biology of the animal, where it lives, and how it interacts with other animals. But it is equally important for those making decisions about the species to understand citizens’ knowledge and perceptions so managers can effectively communicate with the public and help the public participate in planning and decision making activities. Unfortunately, what …

Occurrence And Potential Adverse Effects Of Semivolatile Organic Compounds In Streambed Sediment, United States, 1992–1995, Thomas J. Lopes, Edward T. Furlong Jan 2001

Occurrence And Potential Adverse Effects Of Semivolatile Organic Compounds In Streambed Sediment, United States, 1992–1995, Thomas J. Lopes, Edward T. Furlong

United States Geological Survey: Staff Publications

The occurrence and potential adverse effects of select semivolatile organic compounds (SVOCs) in streambed sediment were assessed at 536 sites in 20 major river basins across the United States from 1992 to 1995. Fifty-six SVOCs were detected at one or more sites, and one or more SVOCs were detected at 71% of sites. The northeastern and Great Lakes regions and large metropolitan areas have the highest SVOC concentrations. Polycyclic aromatic hydrocarbons (PAHs) were detected most frequently and at the highest concentrations. Concentrations of PAHs and phthalates were about 10 times higher at sites influenced by urban activities than at sites …

Introduction: Fear And Loathing Of Evolutionary Psychology In The Social Sciences, Daniel Leger, Alan Kamil, Jeffrey A. French Jan 2001

Introduction: Fear And Loathing Of Evolutionary Psychology In The Social Sciences, Daniel Leger, Alan Kamil, Jeffrey A. French

Department of Psychology: Faculty Publications

When one looks at the intellectual landscape of the modern university, at the scholarly and scientific interests of its faculty, the panorama is seamless. There are no discontinuities. The interests of physicists transmogrify into those of chemists, those of chemists into those of biologists, and so on. The lines, the divisions, between departments have been created out of administrative, not intellectual, necessity.
For example, consider the divide between chemistry and biology. There is a set of chemical processes that are characteristic of living systems. Is the study of these processes chemistry or biology? This is a meaningless question. To be …

The Spatial Distribution Of Diversity Between Disparate Taxa: Spatial Correspondence Between Mammals And Ants Across South Florida, Usa, Craig R. Allen, L. G. Pearlstine, D.P. Wojcik, W.M. Kitchens Jan 2001

The Spatial Distribution Of Diversity Between Disparate Taxa: Spatial Correspondence Between Mammals And Ants Across South Florida, Usa, Craig R. Allen, L. G. Pearlstine, D.P. Wojcik, W.M. Kitchens

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Gap Analysis takes a proactive landscape-level approach to conserving native species by identifying nodes of high biological diversity. It uses vertebrate species richness as an index of overall biological diversity. However, it remains unknownwhether or not the spatial distribution of vertebrate diversity correspondswith the diversity of other taxa. We tested whether landscape-level diversity patterns corresponded between a vertebrate and an invertebrate taxon, mammals and ants, across the southern half of the Florida peninsula, USA. Composite digital maps with a 30-m spatial resolution were produced for each taxon. Spatial correspondence between the taxa was determined by normalizing and then subtracting the …

Do As I Say And Not As I Do: Dickerson, Constitutional Common Law And The Imperial Supreme Court, Kevin Mcnamee Jan 2001

Do As I Say And Not As I Do: Dickerson, Constitutional Common Law And The Imperial Supreme Court, Kevin Mcnamee

Fordham Urban Law Journal

This Comment examines the Supreme Court's Miranda jurisprudence through the lens of the "constitutional common law" theory, which suggests that the Supreme Court has crafted a large body of subconstitutional rules that are not compelled by the text of the Constitution but serve to protect values implicit in the text. As a result, such rules are subject to the limitations of modification and nullification by later courts. After presenting the characteristics of the constitutional common law theory and its relationship to federalism and separation of powers, the author suggests that the theory can explain the erosion of Miranda decision's brightline …

The Everglades Ecosystem: From Engineering To Litigation To Consensus-Based Restoration, John J. Fumero, Keith W. Rizzardi Jan 2001

The Everglades Ecosystem: From Engineering To Litigation To Consensus-Based Restoration, John J. Fumero, Keith W. Rizzardi

St. Thomas Law Review

"The Everglades were dying. The endless acres of saw grass, brown as an enormous shadow where rain and lake water had once flowed, rustled dry." As late as the 1800's, the Everglades consisted of a 60-mile wide shallow river, seldom more than 2 feet deep, flowing from Lake Okeechobee to Florida Bay. That was before the U.S. Army Corps of Engineers erected 1,400 miles of dikes, dams, levees and water control structures in the name of water supply and flood control Now in the year 2000, more than fifty years after Marjory Stoneman Douglas wrote about the demise of the …

The Human Genome In The Public View: Genetics, Geneticists, And Eugenics, Mary Kay Pelias, Nathan J. Markward

St. Thomas Law Review

Recent advances in the technologies of molecular genetics have generated a plethora of questions about how these technologies should be used and what, if any, constraints should be imposed on their use. Commentators on the use of the new genetic technologies have, on the one hand, emphasized the benefits to be realized from genetics research in terms of human health and welfare. On the other hand, a handful of critics have focused on the possible misuses of the new technologies and have urged surveillance of genetics and geneticists, lest we again fall into the morass of coercive, or forcible, eugenics. …

Genetic Breakthroughs And The Limits Of Medicine: Short Stature, Growth Hormone, And The Idea Of Dysfunction, Peter H. Schwartz Jan 2001

Genetic Breakthroughs And The Limits Of Medicine: Short Stature, Growth Hormone, And The Idea Of Dysfunction, Peter H. Schwartz

St. Thomas Law Review

This article reviews arguments that have been presented for the use of growth hormone in some children without growth hormone deficiency. Some of these arguments, this article will claim, utilize confused ideas of dysfunction, and this has led to weak arguments that rely on poor data. Clarifying the concept of dysfunction produces clearer arguments that do not depend on such questionable empirical claims. This analysis aims to serve as a case study of how the careful definition and application of ideas can aid in evaluating the proper purview of medicine. The discussion of future genetic breakthroughs and the powers they …

Nebraska Livestock Nuisance Law

Until 1976 the Nebraska Supreme Court had ruled that animal feeding operations (AFOs) located in rural areas did not legally constitute a nuisance unless the AFO were improperly operated. However, in 1976 the Nebraska Supreme Court ruled that a rural AFO may constitute a nuisance even if properly operated. This decision made AFO operators liable for the first time in Nebraska if their AFO constituted a nuisance.
In 1977 the Nebraska Unicameral adopted an amendment to the Nebraska Environmental Policy Act defining when AFOs would legally constitute a nuisance. Basically, the statute said that an AFO …

Marketing Manure-Part 1

This is part 1 of a two part series discussing the results of a manure marketing survey conducted by the University of Nebraska.
Livestock enterprises have undergone substantial structural change in recent years, including the concentration of livestock and poultry industry into fewer farms (Council for Agricultural Science and Technology, 1996). There has been a reduction in farms with cattle by 50% and farms with swine by 80% between 1965 and 1995 while numbers of hogs and cattle in inventory has stayed nearly constant (USDA, 1965-1995). Livestock and poultry produce, annually, 3.5 and 3.1 million tons of …

Using Weather Stations in Nebraska Livestock Operations

Enforcement of environmental regulations placed on feedlots in Nebraska by the Environmental Protection Agency (EPA), have lead to an increased need for accurate documentation of weather variables. In addition to the need to monitor weather conditions for compliance, an accurate representation of current weather conditions within the microclimate of the livestock operation allow for proactive responses to periods of potential environmental stress periods (i.e. heat and cold stress). Currently, most producers use manual documentation of rainfall events, local weather forecasts and some degree of intuition to monitor weather conditions. Weather station technology exists …

Pivot Irrigation of Livestock Manure
The selection of an appropriate land application method for manure can have an impact on several environmental issues. Individual methods should be evaluated based upon impact on:

• Air quality
• Water quality
• Soil conservation and quality
• Pathogen transmission

The following discussion will review these considerations as they relate to application of manure or lagoon effluent through a center pivot system. A generalized comparison of the relative strengths and weaknesses of alternative application methods is attached in Table 1.

What is an Anaerobic Digester?

The first methane digester plant was built at a leper colony in Bombay, India in 1859. A methane digester system, commonly referred to as an AD (anaerobic digester) is a device that promotes the decomposition of manure or “digestion” of the organics in manure to simple organics and gaseous biogas products. Manure is regularly put into the digester after which the microbes break down the manure into biogas and a digested solid. The digested manure is then deposited into a storage structure. The biogas can be used in an engine generator or burned in a …

Total Reduced Sulfur Concentration in Beef Cattle Feedlots

In 1997, the Nebraska Department of Environmental Quality amended its Title 129 Air Quality Regulations to establish a regulatory threshold for Total Reduced Sulfur (TRS) concentrations under ambient conditions. These thresholds are set at “10.0 parts per million (10.0 PPM) maximum 1 minute average concentration or 0.10 parts per million (0.10 PPM) maximum 30-minute rolling average”. Two agricultural regions of Nebraska with significant cattle finishing in open feedlots came under scrutiny for possible rule violations. In one situation, area feedlots were asked to prepare and implement a TRS control plan.

Il-1Α And Tnf-Α Down-Regulate Crh Receptor-2 Mrna Expression In The Mouse Heart, Sarah C. Coste, Kurt A. Heldwein, Susan L. Stevens, Eric Tobar-Dupres, Mary P. Stenzel-Poore

Faculty Publications

Two receptors (CRH receptor type 1 and CRH receptor type 2) have been identified for the stress-induced neuropeptide, CRH and related peptides, urocortin, and urocortin II. We previously found marked down-regulation of cardiac CRH receptor type 2 expression following administration of bacterial endotoxin, lipopolysaccharide, a model of systemic immune activation, and inflammation. We postulated that inflammatory cytokines may regulate CRH receptor type 2. We show that systemic IL-1α administration significantly down-regulates CRH receptor type 2 mRNA in mouse heart. In addition, TNFα treatment also reduces CRH receptor type 2 mRNA expression, although the effect was not as marked as with …

Valuing Farmland Conservation Easements, Steven B. Mitchell, Bruce B. Johnson Jan 2001

Valuing Farmland Conservation Easements, Steven B. Mitchell, Bruce B. Johnson

Department of Agricultural Economics: Faculty Publications

According to USDA estimates, more than 2 million acres of farmland are developed for urban and other nonagricultural uses each year. Nearly 30 percent of this acreage is considered prime farmland—farmland that has the soil quality, growing season, and moisture supply needed to sustain high yields when managed according to acceptable farming methods. Much of the farmland being lost lies in two of the nation’s major agricultural states, California and Florida, which account for much of the nation’s fruit and vegetable production. However, the land conversion process is occurring in every state to some degree. In Nebraska, thousands of acres …

Proof-Of-Concept: Three Dimensional Pipe Surface Reconstruction From 2d Laser Scanned Image, Matthew Altman Jan 2001

Proof-Of-Concept: Three Dimensional Pipe Surface Reconstruction From 2d Laser Scanned Image, Matthew Altman

Theses

A simulation of three-dimensional models of pipe defect detection systems has been performed. The primary goal is to inspect internal pipe structures for corrosion damage, structural damage, and buildup by driving a video-capture pipe inspection system through the pipe, processing the video, and creating a computer model of the pipe. The software system extracts frames from .avi-format movie files, renders up to thirty frames into a data cube and provides several different methods of visualization. Using commercial-off-the-shelf- technology and components, a simple model for the robotics and optics necessary to scan the interior structure was created. Illumination techniques, extraction algorithms, …
