Generation Of The Transient Electrical And Spontaneous Magnetic Fields By Solid State Combustion, Karen S. Martirosyan, J. R. Claycomb, J. H. Miller Jr., D. Luss Jan 2004

Generation Of The Transient Electrical And Spontaneous Magnetic Fields By Solid State Combustion, Karen S. Martirosyan, J. R. Claycomb, J. H. Miller Jr., D. Luss

Physics & Astronomy Faculty Publications

Experiments revealed that transient electric field intensities up to 2.5 V/cm were generated during the initial period of combustion synthesis of the ferromagnetic products before the maximum temperature was reached. This occurred when the iron particles were partially oxidized and the reaction product was mainly magnetite sFe3O4d. The electromagnetic field caused spontaneous magnetization of the product in the postcombustion zone. Magnetic field values up to 4 µT formed after the sample temperature fell below the Curie temperature and the initial reactants were completely converted to the ferromagnetic phase PbFe12O19. Increasing the volume of the samples increases the absolute residual magnetic …

Spectrum Visualization And Measurement Of Power Parameters Of Microwave Wide-Band Noise, Marina Koledintseva, Alexander A. Kitaytsev, V. A. Konkin, V. Radchenko Jan 2004

Spectrum Visualization And Measurement Of Power Parameters Of Microwave Wide-Band Noise, Marina Koledintseva, Alexander A. Kitaytsev, V. A. Konkin, V. Radchenko

Electrical and Computer Engineering Faculty Research & Creative Works

A method for an adequate visualization of a microwave intense noise spectrum envelope in a wide frequency range (several octaves), measurement of its power parameters, and detection of a narrow-band signal with unknown frequency and power against the noise background is presented. This method is based on an application of a nonheterodyne principle of microwave frequency (and power) conversion using a gyromagnetic converter, which operates in two regimes in turn: the resonance detection and the cross-multiplication. A block scheme and an operation of a two-channel measuring device combining the mentioned functions are discussed.

Book Review Of Chromatography Of Natural, Treated And Waste Waters Edited By T. R. Crompton, John J. Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

T. R. Crompton has accomplished a significant task, summarizing the literature (up to 1998) for the determination of organic and inorganic compounds in a variety of water substrates (surface/natural water, treated water, and waste water). Overall, the book is relatively easy to read; the manuscript produced by the author contains clear tables, figures, and font. The first chapter presents a brief overview of the techniques presented in the book. The author assumes that the reader has a general understanding of chromatography and the basic components of a chromatographic system. The remainder of the book is organized into chapters by chromatographic …

Prevalence Of Neurotoxic Clostridium Botulinum Type C In The Gastrointestinal Tracts Of Tilapia (Oreochromis Mossambicus) In The Salton Sea, P. P. Nol, T. E. Rocke, K. Gross, T. M. Yuill Jan 2004

Prevalence Of Neurotoxic Clostridium Botulinum Type C In The Gastrointestinal Tracts Of Tilapia (Oreochromis Mossambicus) In The Salton Sea, P. P. Nol, T. E. Rocke, K. Gross, T. M. Yuill

United States Department of Agriculture Wildlife Services: Staff Publications

Tilapia (Oreochromis mossambicus) have been implicated as the source of type C toxin in avian botulism outbreaks in pelicans (Pelecanus erythrorhynchos, Pelecanus occidentalis californicus) at the Salton Sea in southern California (USA). We collected sick, dead, and healthy fish from various sites throughout the Sea during the summers of 1999 through 2001 and tested them for the presence of Clostridium botulinum type C cells by polymerase chain reaction targeting the C1 neurotoxin gene. Four of 96 (4%), 57 of 664 (9%), and five of 355 (1%) tilapia tested were positive for C. botulinum type C …

Safety Of Brucella Abortus Strain Rb51 In Black Bears, Steven C. Olsen, Jack Rhyan, T. Gidlewski, Jesse Goff, W. C. Stoffregen

United States Department of Agriculture Wildlife Services: Staff Publications

In two studies conducted from October 1999 to March 2000 and December 2000 to April 2001, adult black bears (Ursus americanus) were orally inoculated with 1.4–3.1X1010 colony-forming units (CFU) of Brucella abortus strain RB51 (SRB51, n=12) or 2 ml of 0.15 M NaCl solution (saline, n=11). We did not detect a difference (P>0.05) in antibody titers to SRB51 in serum obtained before vaccination, at 8 wk after vaccination, or at necropsy at 21 or 23 wk after vaccination between SRB51-vaccinated and nonvaccinated bears. The SRB51 vaccine strain was recovered from tissues obtained at …

Economic Development And Convergence Revisited: The Role Of Agricultural Modernization, Richard Grabowski, Sharmistha Self Jan 2004

Economic Development And Convergence Revisited: The Role Of Agricultural Modernization, Richard Grabowski, Sharmistha Self

Economics Discussion Papers

In earlier debates on economic development, the agricultural sector’s role was somewhat controversial. While dualistic models highlighted the importance of agriculture the mainstream literature placed a greater emphasis on the creation of a modern industrial sector. Soon agriculture disappeared from the mainstream development literature to re-emerge recently with a variety of multiple-sector growth models emphasizing the key role of agriculture. This paper is an empirical cross-country analysis of agriculture’s role in economic development. The focus is the importance of agricultural modernization as a precondition for convergence in postwar growth rates as well as an indicator for overall growth and wellbeing.

Congressional Actions And Public Reactions., Jason Gainous Jan 2004

Congressional Actions And Public Reactions., Jason Gainous

Faculty and Staff Scholarship

This paper explores the link between congressional actions and public attitudes about government responsiveness, public efficacy, and public trust in government. Congressional actions are moves by members of Congress that are potentially consequential to public opinion. The theory contends that actions taken by Congress influence these perspectives on government within an alert stratum of the public. This relationship is demonstrated by employing a pooled time-series logistical regression modeling data that come from the American National Election Studies merged with historical actions data. The findings support the contention that increased actions by Congress increase public efficacy and trust in government, and …

Evidentiary Surrogacy And Risk Allocation: Understanding Imputed Knowledge And Notice In Modern Agency Law, Marin Roger Scordato Jan 2004

Evidentiary Surrogacy And Risk Allocation: Understanding Imputed Knowledge And Notice In Modern Agency Law, Marin Roger Scordato

Scholarly Articles

This article deals with the imputed knowledge rule in agency law. The basic rule imputes to a principal knowledge or notice received by an agent within the scope of the agent's authority. The principal is deemed to have received the information in question even in the absence of any evidence that the agent successfully transmitted it to the principal.

As the article clearly demonstrates, the imputed knowledge rule is currently characterized by complexity and contradiction. The analysis developed in the article suggests that this convolution and uncertainty is the result of the existence of a fundamental tension residing at the …

Functional Feeding Responses Of Coyotes, Canis Latrans, To Fl Uctuating Prey Abundance Inthe Curlew Valley, Utah, 1977–1993 , Rebecca A. Bartel, Frederick F. Knowlton

United States Department of Agriculture Wildlife Services: Staff Publications

We investigated interactions between coyotes (Canis latrans Say, 1823) and prey in the Curlew Valley, Utah, by comparing prey abundances with prey consumption rates. Previous studies reported a cyclic trend in black-tailed jackrabbit (Lepus californicus Gray, 1837) density with a period of 10 years and >150-fold amplitude, as well as short-term fl uctuations among some rodent species that exceeded an 8-fold difference in amplitude over 2 years. Our results suggest changes in coyote diets mainly refl ect the fl uctuations in jackrabbit abundance. Prey switching to rodents during periods of low jackrabbit abundance also was evident. We used the initial …

Seasonal Activity Areas Of Coyotes In The Bear River Mountains Of Utah And Idaho, Glen F. Gantz, Frederick F. Knowlton Jan 2004

Seasonal Activity Areas Of Coyotes In The Bear River Mountains Of Utah And Idaho, Glen F. Gantz, Frederick F. Knowlton

United States Department of Agriculture Wildlife Services: Staff Publications

We studied the seasonal movement patterns and dispersal of coyotes (Canis latrans) in the Bear River Mountains of northern Utah and southern Idaho to determine whether coyotes in this montane region exhibit an altitudinal migration on a seasonal basis. We used 3 locational parameters to assess whether a seasonal altitudinal migration was evident, including overlap in seasonal activity areas, distance between harmonic mean centers of activity, and seasonal differences in mean elevations of locations. Winter and summer activity areas of every mature coyote overlapped, with mean distances between harmonic centers of seasonal activity of 1.5 km (range = 0.4–3.3 km). …

Pest Control: Rodents, Mark E. Tobin, Michael W. Fall Jan 2004

Pest Control: Rodents, Mark E. Tobin, Michael W. Fall

United States Department of Agriculture Wildlife Services: Staff Publications

Rodents are an important and ubiquitous group of mammals that occur as indigenous or introduced species throughout the world. The populations of a relatively few species that live in close association with humans sometimes cause economic damage or become threats to the health of humans or domestic animals. When rodent control efforts are contemplated, the type of problem and the objectives of these efforts should be carefully defined. Successful management of rodent problems depends upon correct identification of the rodent species involved and on obtaining information on the biology, ecology, and behavior of the species in the ecological setting where …

Coyote And Wolf Habitat Use In Northwestern Montana, Wendy M. Arjo, Daniel H. Peltscher Jan 2004

Coyote And Wolf Habitat Use In Northwestern Montana, Wendy M. Arjo, Daniel H. Peltscher

United States Department of Agriculture Wildlife Services: Staff Publications

Being a habitat generalist is an adaptation suategy that has allowed the coyote to expand its range. As wolves reestablish, or are reintroduced, resident populations of coyotes may change habitat use. We compared habitat use between coyotes and wolves in Glacier National Park after successful recolonization by wolves. Two wolf oacks and nine coyotes were monitored from June 1994 throueh June 1997 to determine habitat use in northwestern Montana. Wolves used habitat types within their home ranges in proportion to availability during the winter, but not the summer when more open areas and burned forests were used. Most coyotes used …

Managing Wolf Depredation In The United States: Past, Present, And Future, Stewart W. Breck, Tom Meier Jan 2004

Managing Wolf Depredation In The United States: Past, Present, And Future, Stewart W. Breck, Tom Meier

United States Department of Agriculture Wildlife Services: Staff Publications

With the successful recolonization and reintroduction of wolves (Canis lupus) in parts of the western United States (Bangs and Fritts, 1996; Bangs et al., 1998) and the natural expansion of wolves in the upper Midwest (Fuller et al., 1992; Thiel, 2001), managing conflicts between wolves and livestock is a growing issue for livestock producers, resource professionals, and the general public (Mech, 1996). Unlike the coyote, (Canis latrans) where a great deal is known regarding the biology and ecology of depredation and methods for managing it (Knowlton et al., 1999), very little is known regarding patterns and processes of wolves preying …

Propane Exploders And Electronic Guards Were Ineffective At Reducing Deer Damage In Cornfields, Jason M. Gilsdorf, Scott E. Hygnstrom, Kurt C. Vercauteren, Erin E. Blankenship, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

White-tailed deer (Odocoileus virginianus) cause millions of dollars of damage to agricultural crops annually. We tested the effectiveness of propane exploders and Electronic Guards (Pocatello Supply Depot, Pocatello, Id.) for reducing deer damage in cornfields during the silking–tasseling stage of growth. Track-count indices (F2,7=0.70, P=0.532), corn yields (F2,6=0.14, P=0.873), and estimated damage levels (F2,12=1.45 P=0.272) did not differ between experimental and control fields. The size (F2,11=0.08, P=0.924), location (F2,9=0.30, P=0.750), and percent overlap (F2,9=0.46, P=0.644) of use-areas of radiomarked female deer in the vicinity of experimental fields did not differ among before, during, and after 18-day treatment periods.
