Cross-Polarized Magic-Angle Spinning 13c Nuclear Magnetic Resonance Spectroscopic Characterization Of Soil Organic Matter Relative To Culturable Bacterial Species Composition And Sustained Biological Control Of Pythium Root Rot, Michael J. Boehm, Tianyun Wu, Alex G. Stone, Bart Kraakman, Donna A. Iannotti, G. Edwin Wilson, Laurence V. Madden, Harry A.J. Hoitink

Department of Plant Pathology: Faculty Publications

We report the use of a model system that examines the dynamics of biological energy availability in organic matter in a sphagnum peat potting mix critical to sustenance of microorganism-mediated biological control of pythium root rot, a soilborne plant disease caused by Pythium ultimum. The concentration of readily degradable carbohydrate in the peat, mostly present as cellulose, was characterized by cross-polarized magic-angle spinning 13C nuclear magnetic resonance spectroscopy. A decrease in the carbohydrate concentration in the mix was observed during the initial 10 weeks after potting as the rate of hydrolysis of fluorescein diacetate declined below a critical threshold level …

A Re-Evaluation Of Hotspot Settlement In Lekking Sage Grouse, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Recent analyses of avian leks have come to conflicting conclusions concerning the role of male settlement on female traffic hotspots. This issue was re-examined in the sage grouse, Centrocercus urophasianus, using data on prenesting movements of radio-tagged females and the dispersion of lekking males collected during a 10-year field study. As expected with hotspot settlement, leks were preferentially located in areas through which females traveled between wintering and nesting ranges before mating. In addition, the distribution of males among leks was related proximately to variation in numbers of females visiting each lek during the mating period and ultimately to …

Transmittance And Reflectance Measurements Of Corn Leaves From Plants With Different Nitrogen And Water Supply, James S. Schepers, T. M. Blackmer, Wallace Wilhelm, M. Resende

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Nitrogen is essential for crop production, but also contributes to eutrophication of surface water and degradation of drinking water quality. Modern corn production requires relatively large quantities of N, which are generally supplied by fertilizers. Over-application of N fertilizers and animal wastes frequently results in nitrate leaching. Synchronizing N availability with crop N need offers the potential to protect the environment without sacrificing production. Tools are needed to rapidly and easily monitor crop N status to make timely decisions regarding fertilizer application. Analytical and optical techniques were evaluated with greenhouse grown corn at silking to evaluate several methods to monitor …

Radial Dose Distributions In The Delta-Ray Theory Of Track Structure, Francis A. Cucinotta, Robert Katz, John W. Wilson, Rajendra R. Dubey

Department of Physics and Astronomy: Faculty Publications

The radial dose distribution from delta rays, fundamental to the delta ray theory of track structure, is recalculated. We now include the model of Rudd for the secondary electron spectrum in proton collisions. We include the effects of electron transmission through matter and the angular dependence of secondary electron emission. Empirical formulas for electron range versus electron energy are intercompared in a wide variety of materials in order to extend the track structure theory to arbitrary media. Radial dose calculations for carbon, water, silicon, and gold are discussed. As in the past, effective charge is used to scale to heavier …

The Challenge Of Waste Stewardship And Sustainable Development: A Study Of Municipal Waste Management In Rural Manitoba, C. Emdad Haque, Karen T. Hamberg

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Despite the recent enactment of federal and provincial reduction targets, the majority of government and private sector research has focused primarily on household recycling strategies while little attention was given to other dimensions critical to the achievement of sustainable waste management. Although distinct problems may exist in rural jurisdictions, the literature continues to address the problems inherent in the management of wastes in urban centers rather than rural communities. The aim of this research was to close this gap by examining the issue of municipal waste management in rural Manitoba. Special emphasis was placed upon: (1) the amount and type …

Occupational Segmentation In Kansas And Nebraska, 1890-1900, Lisa M. Frehill

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Population growth in the states of Kansas and Nebraska between 1870-1900 was largely due to the influx of migrants from other parts of the United States and from Europe in search of fertile land to own and till. However, not all migrants were equally successful in attaining this goal. This paper discusses differences in occupational positions of African-American, Native-Born White and Foreign-Born White migrants in Kansas and Nebraska. Evidence from the US. censuses from 1890 and 1900 indicates that African Americans occupied positions of relative disadvantage in the occupational structures of Nebraska and Kansas, being more likely to be relegated …

Populist Entrepreneur: Douglas Bruce And The Tax And Government Limitation Moment In Colorado, 1986-1992, Daniel A. Smith

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

In 1992, Douglas Bruce, a non-practicing lawyer and landlord from Colorado Springs, Colorado, successfully "mobilized" popular support for Amendment 1, a ballot initiative that has restricted the taxing and spending powers of state and local governments in Colorado. For most Coloradans, "Douglas Bruce" is now a household name. Using a historical perspective to examine the role Bruce played in advancing Amendment 1, this study offers the analytic concepts of faux populism, populist entrepreneurs, and the public mood. Faux populism is the transposition of an ill-defined, but tangible public mood into a ready-made ballot initiative that is offered to the people …

Magnetization Reversal Behavior In Cobalt Rare-Earth Thin Films, S.S. Malhotra, Z.S. Shan, D.C. Stafford, Sy_Hwang Liou, David J. Sellmyer

David Sellmyer Publications

Cobalt RareEarth (CoR, R = Pr,Sm) thin films on a Cr underlayer have shown promise as future ultra high density magnetic recording media. The activation volume or the magnetic switching volume (v*) is an important consideration for thermal stability and media noise in high density recording media and V* can also provide information about the magnetization reversal behavior in these films. The magnetic switching volume was estimated for the CoPr films with thicknesses from 28 to 639 nm with a Cr underlayer of 80 nm annealed at 500 ⁰C. The measured switching volume ranges from 1.3 to 1.7x10^{-18 …}

Current Issues In Rabies Prevention In The United States: Health Dilemmas, Public Coffers, Private Interests, Charles E. Rupprecht, Jean S. Smith, John Krebs, Michael Niezgoda, James E. Childs

Zoonotics and Wildlife Disease: Publications

Over the last 100 years, rabies in the United States has changed dramati~ally. More than 90% of all animal rabies cases reported annually to the CDC now occur in wildlife, whereas before 1960 the majority were in domestic animals. The principal rabies hosts today are wild carnivores and bats infected with several viral variants. Annual human deaths have fallen from more than a hundred at the turn of the century to one to two per year despite major outbreaks of animal rabies in several geographic areas. Modem day prophylaxis has proven nearly 100% successful; most human fatalities now occur in …

Monoclonal Antibodies For Detection Of The H7 Antigen Of Escherichia Coli, Yongsheng He, James E. Keen, Ralph B. Westerman, E. Travis Littledike, Jimmy Kwang

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Two murine monoclonal antibodies (MAbs) (2B7 and 46E9-9) reactive with the H7 flagellar antigen of Escherichia coli were produced and characterized. A total of 217 E. coli strains (48 O157:H7, 4 O157:NM, 23 O157:non-H7, 22 H7:non-O157, and 120 non-O157:non-H7), 17 Salmonella serovars, and 29 other gramnegative bacteria were used to evaluate the reactivities of the two MAbs by indirect enzyme-linked immunosorbent assay (ELISA). Both MAbs reacted strongly with all E. coli strains possessing the H7 antigen and with H23- and H24-positive E. coli strains. Indirect ELISA MAb specificity was confirmed by inhibition ELISA and by Western blotting (immunoblotting), using partially …

Lung And Nasal Lesions Caused By A Swine Chlamydial Isolate In Gnotobiotic Pigs, Douglas G. Rogers, Arthur A. Andersen, Breck D. Hunsaker

School of Veterinary and Biomedical Sciences: Faculty Publications

The objective of this study was to determine whether a chlamydial isolate recovered from nasal swabs from swine with pneumonia could cause pneumonia and rhinitis in gnotobiotic pigs. The identity of the isolate currently is unknown, but it shares characteristics with Chlamydia trachomatis. After propagation in Vero cells and preparation of the inoculum (2.5 x 1010 inclusion-forming units/ml), Chlamydiae were instilled into nostrils (1.0 ml/nostril) and lungs (2.0 ml intralaryngeally) of 15 anesthetized 3-day-old gnotobiotic piglets. Five age-matched gnotobiotic piglets were anesthetized and sham infected with uninfected cell culture lysates. Two treated piglets were moribund and 2 were severely …

High Coercivity Smfesic Films Fabricated By Multilayer Sputtering, S.Y. Zhang, Z.S. Shan, Yi Liu, David J. Sellmyer

David Sellmyer Publications

SmFeSiC thin films have been obtained by sputtering SmFe/C(Si) multilayers with a Ta underlayer on Si substrates and subsequently annealing at 700° C. The coercivity of the SmF films strongly depends on the sputtering and annealing conditions. The influence of the thickness of the Ta underlayer, the thickness ratio of SmFe to C(Si), the argon pressure and heat treatment In- plane Coercivities up to 7.2 kOe and squareness of 0.94 were obtained.

Lorentz Microscopy Observation Of Magnetic Grains In Co-Sm // Cr Films, Yi Liu, Z.S. Shan, David J. Sellmyer

David Sellmyer Publications

This paper presents our recent Lorentz microscopy study of magnetic domain structure and its relation to the nanostructure of Co-Sm films. The magnetic domains were imaged by Foucault Lorentz mode and the corresponding nanostructure was revealed by bright field and high resolution images. The nanostructure is composed of clusters of 20 nm grown on Cr grains. Each cluster is formed by the amorphous matrix and about 5 nm crystallites distributed in the matrix. It is found that each cluster forms a magnetic grain. Such magnetic grains show uniform contrast near the magnetic domain wall, and correspond to the switching volume …
