A New Species Of Linstowia (Cestoda: Anoplocephalidae) From Marsupials In Bolivia, Scott Lyell Gardner, Mariel L. Campbell Oct 1992

A New Species Of Linstowia (Cestoda: Anoplocephalidae) From Marsupials In Bolivia, Scott Lyell Gardner, Mariel L. Campbell

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of cestode of the genus Linstowia (Cestoda: Anoplocephalidae) is described from marsupials of the genera Thylamys and Monodelphis. The new species (Linstowia schmidti) differs from L. iheringi Zschokke, 1904, in having a much smaller strobila and reduced number of proglottids, and in the distribution of the eggs in gravid proglottids. In Bolivia, cestodes of the genus Linstowia appear to have a restricted geographic distribution, occurring in marsupials only in southeastern Bolivia near the western margin of the Chaco. This host-parasite association may represent an ecological-historical relict.


Critical Comment: Designation And Curatorial Management Of Type Host Specimens (Symbiotypes) For New Parasite Species, Jennifer K. Frey, Terry L. Yates, Donald Duszynski, William L. Gannon, Scott Lyell Gardner Oct 1992

Critical Comment: Designation And Curatorial Management Of Type Host Specimens (Symbiotypes) For New Parasite Species, Jennifer K. Frey, Terry L. Yates, Donald Duszynski, William L. Gannon, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The accurate identification of a host organism is an important component in the taxonomic recognition of a new species of parasite. Correct identification, curatorial management, and safekeeping of the host specimen from which a parasite type specimen is collected is also desirable. We recommend that the host from which the type of a new parasite species is described should be designated as a symbiotype.

Department of Civil and Environmental Engineering: Faculty Publications

One full-scale vehicle crash test was conducted on the Nebraska Turned-Down Approach Terminal Section. Test NETD-1 was conducted with a 1984 Dodge Colt weighing 1,887-lbs (test inertial). Impact conditions were 59.0 mph and 0 degrees with a 1.25-ft offset toward the roadway.

The test was conducted and reported in accordance with the requirements specified in the Recommended Procedures for the Safety Performance Evaluation of Highway Appurtenances, National Cooperative Highway Research Program (NCHRP) Report No. 230. The safety performance of the Nebraska Turned-Down Approach Terminal Section was determined to be unacceptable according to the NCHRP 230 criteria.


Collapse Of The Proton Motive Force In Listeria Monocytogenes Caused By A Bacteriocin Produced By Pediococcus Acidilactici, Douglas P. Christensen, Robert W. Hutkins Oct 1992

Collapse Of The Proton Motive Force In Listeria Monocytogenes Caused By A Bacteriocin Produced By Pediococcus Acidilactici, Douglas P. Christensen, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

The effect of pediocin JD, a bacteriocin produced by Pediococcus acidilactici JD1-23, on the proton motive force and proton permeability of resting whole cells of Listeria monocytogenes Scott A was determined. Control cells, treated with trypsin-inactivated bacteriocin at a pH of 5.3 to 6.1, maintained a pH gradient and a membrane potential of approximately 0.65 pH unit and 75 mV, respectively. However, these gradients were rapidly dissipated in cells after exposure to pediocin JD, even though no cell lysis had occurred. The pH gradient and membrane potential of the producer cells were also unaffected by the bacteriocin. Whole cells treated …


Nio(100) Valence-Band Density Of States During Hydrogen Reduction , K.W. Wulser, B.P. Hearty, Marjorie Langell Oct 1992

Nio(100) Valence-Band Density Of States During Hydrogen Reduction , K.W. Wulser, B.P. Hearty, Marjorie Langell

Marjorie A. Langell Publications

Photoelectron spectroscopy with incident photons of 40–120 eV has been used to determine the valence-band structure of NiO(100) as the surface undergoes slow hydrogen reduction. Low pressure and moderate temperature conditions (1.3×10-2 Pa and 625 K) allow oxygen to be removed from the near-surface region with a minimal disruption in the NiO(100) substrate. Both NiO(100) ultraviolet photoemission spectroscopy (UPS) and low-energy electron-diffraction features persist at NiO(100) reduced surfaces throughout the reduction process. In addition, reduced nickel features slowly grow into the UP spectra, with the most intense peak found in the NiO band gap. Chemisorbed hydrogen, hydroxyls, and oxygen …

Interval Estimation And Monte Carlo Simulation Of Digital Communication Systems, Kurt Louis Kosbar, T. F. Chang Oct 1992

Interval Estimation And Monte Carlo Simulation Of Digital Communication Systems, Kurt Louis Kosbar, T. F. Chang

Electrical and Computer Engineering Faculty Research & Creative Works

This work quantifies the accuracy of bit error rate (BER) estimates produced by Monte Carlo simulations by carefully applying confidence interval estimation techniques. Due to numerical difficulties, some previous work in this area has assumed that the BER statistic possessed a Gaussian distribution. This work demonstrates that in some important regions the estimate is decidedly non-Gaussian, and application of central limit theorem arguments can result in errors in excess of an order of magnitude. This work investigates the accuracy of common approximations and the feasibility of exact calculation of confidence intervals, and presents a novel polynomial class approximation. By combining …


Construction Of Highway Base And Subbase Layers Containing Residue From An Atmospheric Fluidized Bed Combustion Process, David Q. Hunsucker, R. Clark Graves Oct 1992

Construction Of Highway Base And Subbase Layers Containing Residue From An Atmospheric Fluidized Bed Combustion Process, David Q. Hunsucker, R. Clark Graves

Kentucky Transportation Center Research Report

This report summarizes findings of laboratory and construction evaluations of using residue from an atmospheric fluidized bed combustion (AFBC) process as a component in an experimental road base and subbase application. The base mixture contains pulverized fuel ash, AFBC residue, and limestone aggregates used as bulk filler. The subbase mixture contains AFBC residue and pond ash (ponded fly ash and bottom ash). Mixtures containing various proportions of each component were evaluated in the laboratory relative to maximum dry density, optimum moisture content, and compressive strength development.

Two 750-foot test sections of a 22-foot wide roadway, containing the experimental mixtures, were …

Cost Effective Maintenance Contracting, Bobby W. Meade, David Q. Hunsucker

Kentucky Transportation Center Research Report

Increased emphasis on highway maintenance and the need to accomplish the maintenance programs as efficiently as possible, prompted this study. The objectives of the study addressed herein are the identification of maintenance activities performed by contract, determination of equivalent levels of service between contract performed and in-house performed activities, cost comparison of those activities, and recommendations to implement the findings.

Findings are that activities routinely performed by contract are cost efficient. A formal make-versus-buy decision making process should be developed. The process should be made available to District personnel and the make-versus-buy decision made at that level. Decision making processes …


Transient Simulation Of A Trombe Wall Passive Heating System Coupled To A Thermally Stratified Room, Ali Saleh Kheireddine Oct 1992

Transient Simulation Of A Trombe Wall Passive Heating System Coupled To A Thermally Stratified Room, Ali Saleh Kheireddine

Mechanical & Aerospace Engineering Theses & Dissertations

Thermal performance of a Trombe-wall space heating system has been studied numerically for one-day and multiple-day periods. This study analyzes the system performance by simultaneously considering the coupled nature of the channel convection, wall heat conduction and transient room energy balance. A computer program has been written and implemented to assess the effects of system parameters, weather conditions and peak temperature control strategies on the system performance.

The system performance is influenced by such system parameters as the storage wall thickness, channel width and the temperature stratification in the room. Increasing the wall thickness decreases the temperature swings considerably, but …


Ground Water Investigation Of The Petersburg Granite In Chesterfield County, Virginia, Michael W. Bennett Oct 1992

Ground Water Investigation Of The Petersburg Granite In Chesterfield County, Virginia, Michael W. Bennett

OES Theses and Dissertations

Yields of new water wells in areas underlain by the Petersburg Granite in Chesterfield County, Virginia should improve if procedures for site selection and well construction follow the new guidelines proposed. These guidelines integrate analyses of aerial photo linears and drainage patterns, survey of bedrock joints and shallow geophysical properties and techniques using several statistical methods.

Throughout the study area, fracture traces form in nearly the same orientation as bedrock fractures. The dominant N-S and E-W trending bedrock joints also corresponded to aerial photo linears of similar orientation.

Across one large fracture zone, both gamma-ray and electrical resistivity surveys reveal …

Retention Of Cellular Viability And Growth Potential In Cryopreserved Bovine Arterial Tissue: Implications For Clinical Use Of Cryopreserved Vascular Allografts, Kip G. Gardner Oct 1992

Retention Of Cellular Viability And Growth Potential In Cryopreserved Bovine Arterial Tissue: Implications For Clinical Use Of Cryopreserved Vascular Allografts, Kip G. Gardner

Biological Sciences Theses & Dissertations

Segments of bovine calf aortas and pulmonary arteries were cryopreserved at -196° C for two weeks to 18 months and subsequently thawed. Cellular morphology, viability, and growth potential in these segments were then compared with the same attributes in segments from fresh (control) arteries. Scanning electron microscopy revealed no disruption of intimal surfaces attributable to cryopreservation. Endothelial cells were successfully cultured from all cryopreserved arterial segments. Endothelial monolayers grown from cryopreserved arteries had a cobblestone appearance and expressed Factor VIII antigen but not smooth muscle alpha-actin. Plating efficiency in primary cultures of endothelial cells was lower for cryopreserved arteries than …


A Multivariate Characterization Of Assemblages Of Planktonic Mysids Decapods And Sergestids In The Chesapeake Bay Mouth Area, John Charles Seibel Oct 1992

A Multivariate Characterization Of Assemblages Of Planktonic Mysids Decapods And Sergestids In The Chesapeake Bay Mouth Area, John Charles Seibel

Biological Sciences Theses & Dissertations

This study is the first to focus on the assemblages of the planktonic mysids, decapods, and sergestids found in the lower Chesapeake Bay. The assemblages of these organisms in the lower Chesapeake Bay and nearby shelf were characterized using three different statistical approaches, and the methods used were evaluated for their effectiveness at delineating ecologically meaningful assemblages. Three stations were sampled across the Chesapeake mouth and one offshore, with oblique and neuston net tows. Twenty-seven larval stages, representing at least 23 species, were found in sufficient numbers to be analyzed statistically. The statistical approaches were each based upon a different …
