Part Form Errors Predicted From Machine Tool Performance Measurements, R. G. Wilhelm, N. Srinivasan, F. Farabaugh, R. Hocken

Department of Mechanical and Materials Engineering: Faculty Publications

Machine tool performance testing, as defined by IS0 230 and ANSI B5.54 has been successfully used to maintain and improve the accuracy and repeatability of production-level machine tools. In this study, a controlled series of experiments have been used to test the efficacy of these performance tests in the prediction of part form errors. Results are shown for flatness, squareness, position, and profile tolerances. The experimental results suggest that standard machine tool performance tests can also be used to predict the “best-case” tolerances that can be achieved for particular part features.

Perspectives On The Diagnosis, Epizootiology, And Control Of The 1973 Duck Plague Epizootic In Wild Waterfowl At Lake Andes, South Dakota, Gary Pearson, Delmar Cassidy

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

An epizootic of duck plague occurred in early 1973 in a population of 163,500 wild waterfowl, primarily mallards (Anas platyrhynchos), wintering on Lake Andes and the nearby Missouri River in southeastern South Dakota (USA). The diagnosis was based on pathologic lesions and confirmed by virus isolation. Control measures included quarantine, attempts to reduce virus contamination of the area, dispersal of waterfowl, and monitoring of wild waterfowl populations for mortality. The epizootic resulted in documented mortality of 18% and estimated mortality of 26% of the waterfowl at risk. Prompt implementation of control measures might have limited mortality to approximately …

A Meta-Analysis Of The Effects Of Organizational Behavior Modification On Task Performance, 1975-95, Alexander D. Stajkovic, Fred Luthans

Department of Management: Faculty Publications

Results of a primary meta-analysis indicated a significant main effect of the organizational behavior modification (O.B. Mod.) approach on task performance (d. = .51; a 17 percent increase) and a significant treatment-by-study interaction. To account for within-group heterogeneity of effect sizes, we conducted a two-level theory-driven moderator analysis by partitioning the sample of studies first into manufacturing and service groups and then into seven classes of reinforcement interventions. Results indicated a stronger average effect of O.B. Mod. in manufacturing organizations, moderation by the type of contingent interventions, and "pairwise" differences among average effect sizes in both organizational types. The practical …

Selected Physical Properties Of Jointed Goatgrass (Aegilops Cylindrica Host.), C. M. Hubbard, Curtis L. Weller, David D. Jones

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Selected physical properties of jointed goatgrass samples collected in western Nebraska and eastern Colorado were determined. Measured properties were spikelet dimensions (length 10.8 ± 0.35 mm; width 2.59 ± 0.25 mm), particle density (0.761 ± 0.016 g/m³), bulk density (351 ± 26.9 kg/m³), terminal velocity (301 ± 25.9 m/min), angle of repose (26.3 ± 0.286°), internal coefficient of friction (0.494 ± 0.007), and equilibrium moisture contents at 10% RH (6.56 ± 1.03% w.b.), 30% RH (7.43 ± 1.21% w.b.), 50% RH (9.01 ± 0.67% w.b.), 70% RH (11.89 ± 0.61% w.b.), and 90% RH (20.39 ± …

Runoff, Erosion, And Soil Quality Characteristics Of A Former Conservation Reserve Program Site, John E. Gilley, John W. Doran, Douglas Karlen, T. C. Kaspar

Department of Agricultural and Biological Systems Engineering: Faculty Publications

No-till and moldboard plow tillage systems were established on a former Conservation Reserve Program (CRP) site in southwest Iowa. Runoff rates from simulated rainfall events were significantly greater on sites returned to crop production than from adjoining, undisturbed CRP areas. Substantial soil loss was measured from the moldboard plow treatments, but no significant differences in erosion rates were found between the undisturbed CRP and no-till management systems. No-till management maintained levels of soil quality similar to those of CRP by preserving soil structural integrity and reducing losses of soil organic matter (SOM) associated with tillage. Conservation tillage systems which maintain …

Relationship Between Yeast Polyribosomes And Upf Proteins Required For Nonsense Mrna Decay, Audrey L. Atkin, Laura R. Schenkman, Margot Eastham, Jeffrey N. Dahlseid, Michael J. Lelivelt, Michael R. Culbertson

School of Biological Sciences: Faculty Publications

In yeast, the accelerated rate of decay of nonsense mutant mRNAs, called nonsense-mediated mRNA decay, requires three proteins, Upf1p, Upf2p, and Upf3p. Single, double, and triple disruptions of the UPF genes had nearly identical effects on nonsense mRNA accumulation, suggesting that the encoded proteins function in a common pathway. We examined the distribution of epitope-tagged versions of Upf proteins by sucrose density gradient fractionation of soluble lysates and found that all three proteins co-distributed with 80 S ribosomal particles and polyribosomes. Treatment of ly-sates with RNase A caused a coincident collapse of polyribosomes and each Upf protein into frac-tions containing …

Estimation Of Directional Surface Wave Spectra From A Towed Research Catamaran, Kurt A. Hanson, Tetsu Hara, Erik J. Bock, Andrew B. Karachintsev

Graduate School of Oceanography Faculty Publications

During the High-Resolution Remote Sensing Main Experiment (1993), wave height was estimated from a moving catamaran using pitch-rate and roll-rate sensors, a three-axis accelerometer, and a capacitive wave wire. The wave spectrum in the frequency band ranging roughly from 0.08 to 0.3 Hz was verified by independent buoy measurements. To estimate the directional frequency spectrum from a wave-wire array, the Data-Adaptive Spectral Estimator is extended to include the Doppler shifting effects of a moving platform. The method is applied to data obtained from a fixed platform during the Risø Air–Sea Experiment (1994) and to data obtained from a moving platform …

An Empirical Eigenfunction Analysis Of Sea Surface Temperatures In The Western North Atlantic, Richard Everson, Peter C. Cornillon, Lawrence Sirovich, Andrew Webber

Graduate School of Oceanography Faculty Publications

The empirical orthogonal function decomposition is used to analyze time records of AVHRR sea surface temperature observations of the western North Atlantic from 32.9° to 43.6°N, 62.7° to 76.3°W. A manually declouded dataset covering the spring of 1985 is analyzed. The majority (80%) of the variance about the mean is accounted for by an empirical eigenfunction, which is identified with seasonal warming. This eigenfunction shows that the shelf water, excluding Georges Bank, warms the most rapidly; the surface water of the Gulf of Maine warms a little less rapidly and the Gulf Stream and Sargasso Sea surface water warm the …

Local Exchange Services In The Next Century -- What Still Must Be Done To Bring Us To Where We Want To Be?, Hullihen Williams Moore, Richard L. Cimerman, John J. Langhauser, Philip Mcclelland, Mark J. Mathis

Richmond Journal of Law & Technology

Our panel is Local Exchange Service in the Next Century--What Still must be Done to Bring Us to Where We Want to Be? We have four excellent panelists to address these questions. I expect the panelists to agree, in part, where we want to be, and they won't spend a whole lot of time about increased service, new technology, lower prices, and all those things. I am sure we'll hear some assurances along those lines, at least from three of the panelists. Most of the time will be spent on what still must be done to get us there. I …

Net Law: How Lawyers Use The Internet, G. Wingate Grant

Richmond Journal of Law & Technology

We have all had experiences where we listened to a preacher or maybe a law professor use a story to illustrate a point. Weeks later, we might not recall the point, but we remember the story. That was my feeling after reading through NET LAW: HOW LAWYERS USE THE INTERNET. This book might be considered a dictionary, a marketing book, or a computer book. Most significantly, it is an anthology of actual accounts of lawyers and their staffs successfully using the Internet to make their practices more efficient and, in some cases, lucrative. Now that I have your attention, let …

The Supreme Court's "Exceedingly [Un]Persuasive" Application Of Intermediate Scrutiny In United States V. Virginia, Jeffrey A. Barnes

University of Richmond Law Review

The Supreme Court's decision in the case of United States v. Virginia in June of 1996 was a landmark decision that could change how future courts approach and resolve gender-based equal protection claims. The Supreme Court held that the Virginia Military Institute (VMI) could no longer continue its male-only admissions policy as a state-funded institution of higher education. The Court's apparent heightening of the level of scrutiny applied to gender-based classifications from the previously used intermediate scrutiny to an ambiguous standard either somewhere between the traditional intermediate scrutiny and strict scrutiny, or, in effect, a standard equivalent to strict scrutiny, …

Tumor Immunity Following Adenovirus Mediated Herpes Simplex Thymidine Kinase Gene Transfer To Experimental Rat Gliomas, Maulik Raj Shah

Theses and Dissertations

Previous studies have determined adenovirus mediated herpes simplex thymidine kinase gene transfer (AV-TK) to be effective for the treatment of experimental gliomas. In this study we report three distinct phenomenon. First, animals with complete regression of subcutaneous tumors upon intratumoral injections of AV-TK with concomitant Ganciclovir® (GCV) administration developed tumor immunity. These animals had the ability to reject a subsequent inoculum of lethal doses of tumor cells. This tumor immunity was long standing and protective as far as 6 months from the time of initial tumor ablation. Of interest, adoptive transfer of splenocytes from AV-TK treated-tumor ablated animals to naive …

Electrowinning Of Nonnoble Metals With Simultaneous Hydrogen Evolution At Flow-Through Porous Electrodes Iii. Time Effects, Mahmoud M. Saleh, John W Weidner, Bahgat E. El-Anadouli, Badr G. Ateya

Faculty Publications

The electrowinning of zinc from a recirculating alkaline zincate solution at a flow-through porous electrode was investigated. Experimental results were obtained to test the predictions of a mathematical model. The effects of electrolyte flow rate, cell current, and electrode thickness on the concentration-time relations and coulombic efficiency-time relations were studied. The experimental results show that the highest recovery rate was obtained at both high flow rates and cell currents. There is, however, a practical limit for increasing both the cell current and the electrolyte flow rate. Reasonable agreement between the model predictions and experimental results was obtained. A case study …

An Electrochemical Route For Making Porous Nickel Oxide Electrochemical Capacitors, Venkat Srinivasan, John W. Weidner

Faculty Publications

Porous nickel oxide films were prepared by electrochemically precipitating nickel hydroxide and heating the hydroxide in air at 300°C. The resulting nickel oxide films behave as an electrochemical capacitor with a specific capacitance of 59 F/g electrode material. These nickel oxide films maintain high utilization at high rates of discharge (i.e., high power density) and have excellent cycle life. Porous cobalt oxide films were also synthesized. Although the specific capacitances of these films are approximately one-fifth that of the nickel oxide films, the results demonstrate the versatility of fabricating a wide range of porous metal oxide films using …

Molecular-Level Modeling Of The Viscoelasticity Of Crosslinked Polymers: Effect Of Time And Temperature, Philip P. Simon, Harry J. Ploehn

Faculty Publications

We present a new molecular-level picture of chain dynamics for describing the viscoelasticity of crosslinked polymers. The associated mathematical model consists of a time-dependent momentum balance on a representative polymer segment in the crosslinked network, plus phenomenological expressions for forces acting on the segments. These include a cohesive force that accounts for intermolecular attraction, an entropic force describing the thermodynamics governing chain conformations, and a frictional force that captures the temperature dependence of relative chain motion. We treat the case of oscillatory uniaxial deformation. Solution of the model equations in the frequency domain yields the dynamic moduli as functions of …

Canopy Architecture And Morphology Of Switchgrass Populations Differing In Forage Yield, Daren D. Redfearn, Kenneth J. Moore, Kenneth P. Vogel, Steven S. Waller, Robert B. Mitchell

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

Phenotypic selection has been used to improve forage yield and in vitro dry matter disappearance (IVDMD), but the effects on canopy architecture and morphology are not understood. Our objectives were to determine if canopy architecture and morphology can explain genotype x environment (G x E) yield differences in switchgrass (Panicum virgatum L.) and to evaluate canopy architecture and morphology as selection criteria for increasing yield. This study was conducted in 1993 near Mead, NE, and near Ames, IA. The experimental design was a randomized complete block experiment with a split-plot arrangement of four replicates at each location. Whole plots …
