Reconstructing The Unity Of Mathematics Circa 1900, David J. Stump

Philosophy

Standard histories of mathematics and of analytic philosophy contend that work on the foundations of mathematics was motivated by a crisis such as the discovery of paradoxes in set theory or the discovery of non-Euclidean geometries. Recent scholarship, however, casts doubt on the standard histories, opening the way for consideration of an alternative motive for the study of the foundations of mathematics -- unification. Work on foundations has shown that diverse mathematical practices could be integrated into a single framework of axiomatic systems and that much of mathematics could be expressed in a single language. The new framework was the …

Punitive Damages After Bmw V. Gore (1996), Fred W. Morgan, Karl Boedecker

Economics, Law, and International Business

The U.S. Supreme Court handed down its decision in BMW v. Gore (1996) in May. This decision triggered another round of discussions regarding restraints on punitive damages as a part of the overall reform of the U.S. tort system. Here, the authors review the BMW decision and its immediate predecessors to illustrate the essential public policy issues that are associated with proposed limits on punitive damages.

Western Australia Soil Acidity Research And Development Update 1997 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

There is a lot of lime being spread in Western Australia – or is there?

In fact, the Australian Bureau of Statistics agricultural census paints a picture showing that we are still far short of the amount of lime that should be getting on to the ground.

For many years Western Australian soils acidified without significant production penalties. The soil pH was at values that were not affecting plant growth. However, over the last decade or so, large areas of soils have reached the point where production is being affected. In addition, we are now introducing plant species such as …

Detecting Fire And Grazing Patterns In Tallgrass Prairie Using Spectral Mixture Analysis, Carol A. Wessman, C Ann Bateson, Tracy Benning

Environmental Science

Global grasslands are typically under management practices (such as fire and grazing) that alter nutrient cycling, ecosystem composition, and distribution of organic matter from the unmanaged condition. We evaluated landscape-level response to fire and grazing treatments in the Konza Tallgrass Prairie Research Natural Area, Kansas, using spectral mixture analysis of Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data acquired 31 August 1990. Spectral mixture analysis derives the fractional abundances of spectrally unique components in the landscape. The reflectance spectra of these components are called endmembers. Endmember fractions values were compared against ground values of live biomass, current standing dead biomass, and litter …

Identification Of The Adp-L-Glycero-D-Manno-Heptose-6-Epimerase (Rfad) And Heptosyltransferase Ii (Rfaf) Biosynthesis Genes From Nontypeable Haemophilus Influenzae 2019, W A. Nichols, B W. Gibson, William Melaugh, N G. Lee, M Sunshine, M A. Apicella

Chemistry Faculty Publications

Haemophilus influenzae is an important human pathogen. The lipooligosaccharide (LOS) of H. influenzae has been implicated as a virulence determinant. To better understand the assembly of LOS in nontypeable H. influenzae (NtHi), we have cloned and characterized the rfaD and rfaF genes of NtHi 2019, which encode the ADP-L-glycero-D-manno-heptose-6-epimerase and heptosyltransferase II enzymes, respectively. This cloning was accomplished by the complementation of Salmonella typhimurium lipopolysaccharide (LPS) biosynthesis gene mutants. These deep rough mutants are novobiocin susceptible until complemented with the appropriate gene. In this manner, we are able to use novobiocin resistance to select for specific NtHi LOS inner core …

Characterization Of A Transposon Tn916-Generated Mutant Of Haemophilus Ducreyi 35000 Defective In Lipooligosaccharide Biosynthesis, B W. Gibson, A A. Campagnari, William Melaugh, M A. Apicella, S Grass, Jing Wang, Katherine L. Palmer, R S. Munson

Chemistry Faculty Publications

To define the role of the surface lipooligosaccharide (LOS) of Haemophilus ducreyi in the pathogenesis of chancroid, Tn916 mutants of H. ducreyi 35000 defective in expression of the murine monoclonal antibody (MAb) 3F11 epitope on H. ducreyi LOS were identified by immunologic screening. One mutant, designated 1381, has an LOS which lacks the MAb 3F11 epitope and migrates with an increased mobility on sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The gene disrupted by the Tn916 element in strain 1381 was identified by cloning the sequences flanking the Tn916 element. The sequences were then used to probe a lambda DASHII genomic library. …

Late Holocene Eolian Activity In The Mineralogically Mature Nebraska Sand Hills, Daniel R. Muhs, Thomas W. Stafford Jr., James B. Swinehart, Scott D. Cowherd, Shannon A. Mahan, Charles A. Bush, Richard F. Madole, Paula B. Maat

School of Natural Resources: Faculty Publications

The age of sand dunes in the Nebraska Sand Hills has been controversial, with some investigators suggesting a full glacial age and others suggesting that they were last active in the late Holocene. New accelerator mass spectrometry radiocarbon ages of unaltered bison bones and organic rich sediments suggest that eolian sand deposition occurred at least twice in the past 3000 ^I4C yr B.P. in three widely separated localities and as many as three times in the past 800 ¹⁴C yr at three other localities. These late Holocene episodes of eolian activity are probably the result of droughts more …

Monitoring Of Polluted Water Bodies By Remote Sensing, Anatoly A. Gitelson, Robert Stark, Gideon Oron, Inka Dor

School of Natural Resources: Faculty Publications

The purpose of this study is to evaluate a remote sensing method for real time monitoring of wastewater effluent. Reflectance in the range from 400 to 950 nm with a spectral resolution of 2 nm, simultaneously with turbidity, chlorophyll and total suspended matter contents were acquired in two wastewater systems: R "m and Naan, Israel. The reflectance spectra of wastewater effluent were investigated in order to develop algorithms for remote estimation of wastewater quality expressed as chlorophyll-α, bacteriochlorophyll-α, non-organic and total suspended matter concentrations. Reflectance height at 720 nm and an area above the base line from 670 to 950 …

Ecological Water Treatment System For Removal Of Phosphorus And Nitrogen From Polluted Water, Ray W. Drenner, Donald J. Day, Stacy J. Basham, J. Durward Smith, Susan I. Jensen

School of Natural Resources: Faculty Publications

We propose that phosphorus and nitrogen can be removed from polluted water using an ecological water treatment system consisting of periphyton and fish. In the proposed system, polluted water flows through a series of vessels, and the nutrients are taken up by periphyton growing on porous screens. Algal-grazing fish feed on the periphyton and either assimilate or egest the nutrients in mucus-bound feces that settle from the water into a sediment trap. Both the fish and their feces can be harvested as nutrient sinks. In this study we examined the effects of an algal-grazing cichlid (Tilapia mossambica) and …

Elimination Of Supply Harmonics, Stephen L. Clark, P. Famouri, W. L. Cooley

Mathematics and Statistics Faculty Research & Creative Works

The price of the extensive use of power electronic devices is becoming clear: increasing harmonic "pollution." The greater amount of harmonics being introduced into power distribution systems is of concern to both power consumers and power companies. First, a brief look is taken at background information which describes harmonic sources, effects, and characteristics. Then the evolution of the harmonics elimination approaches of current compensation and active filtering are discussed to give some insight into the directions that research is taking.

On The Behavior Of The Solutions Of The Navier-Stokes Equations At Vanishing Viscosity, Roger Temam, Xiaoming Wang

Mathematics and Statistics Faculty Research & Creative Works

In this article we establish partial results concerning the convergence of the solutions of the Navier-Stokes equations to that of the Euler equations. Namely, we prove convergence on any finite interval of time, in space dimension two, under a physically reasonable assumption. We consider the flow in a channel or the flow in a general bounded domain.

Disconjugacy And Transformations For Symplectic Systems, Martin Bohner, Ondřej Došlý

Mathematics and Statistics Faculty Research & Creative Works

We examine transformations and diconjugacy for general symplectic systems which include as special cases linear Hamiltonian difference systems and Sturm-Liouville difference equations of higher order. We give a Reid roundabout theorem for these systems and also for reciprocal symplectic systems. Particularly, we investigate a connection between eventual disconjugacy of linear Hamiltonian difference systems and their reciprocals. Finally, we present a dinsconjugacy-preserving transformation of a Sturm-Liouville equation of higher order which transforms this equation into another one of the same order.

Electron-Impact Total Ionization Cross Sections Of Silicon And Germanium Hydrides, M. A. Ali, Y.-K. Kim, W. Hwang, N. M. Weinberger, M. Eugene Rudd

M. Eugene Rudd Publications

Electron-impact total ionization cross sections of some silicon and germanium compounds have been calculated by applying a new theoretical model that has been found to be reliable for a wide range of molecules. The new theory, the binary-encounter-Bethe (BEB) model, combines the binary-encounter theory and the Bethe theory for electron-impact ionization, and uses simple theoretical molecular orbital data—binding energies, average kinetic energies, and occupation numbers—which are readily available from molecular structure codes. Total ionization cross sections of SiH, SiH₂, SiH₃, SiH₄, Si₂H₆, Si(CH₃)₄, GeH, GeH_{2 …}
