Electron-Density Studies Of Metal–Metal Bonds. I. The Deformation Density Of Ti2O3 At 295 K, M. G. Vincent, K. Yvon, A. Gruttner, J. Ashkenazi
Electron-Density Studies Of Metal–Metal Bonds. I. The Deformation Density Of Ti2O3 At 295 K, M. G. Vincent, K. Yvon, A. Gruttner, J. Ashkenazi
Physics Articles and Papers
The electron-density distribution in Ti2O3 at room temperature has been determined from single-crystal X-ray diffraction data. The deformation maps show maxima of 0.15 e Å-3 between the Ti atoms sharing a common face of O-atom octahedra, and maxima of 0.18 e Å-3 between the O atoms and their four nearest Ti neighbours. These observations support the general view concerning the bonding in Ti2O3 and correlate well with the results of theoretical band-structure calculations. In particular, they confirm the existence of a metal-metal bond which is directed parallel to the ternary axis and …

Electron-Density Studies Of Metal-Metal Bonds. Ii. The Deformation Density Of V2O3, M. G. Vincent, K. Yvon, J. Ashkenazi
Physics Articles and Papers
The charge-density distribution in V2O3 differs from that in Ti2O3 mainly with respect to the deformation of the metal atoms. The V atoms show a positive deformation of up to 0.1 e Å-3 perpendicular to c in a plane containing three nearest V-atom sites across the edges of the surrounding O-atom octhedra, and a negative deformation of up to 0.3 e Å-3 parallel to c between the nearest V-atom site across the faces of the O-atom octahedra. These observations are in accordance with theoretical band-structure calculations and confirm the existence of an …
Use Of Annual Legumes As Winter Cover For No-Till Corn, Robert L. Blevins
Use Of Annual Legumes As Winter Cover For No-Till Corn, Robert L. Blevins
Soil Science News and Views
Legumes in crop rotations hsve traditionally provided nitrogen for nonlegume crops since the early history of agriculture. When in association with the proper strains of Rhyzobium bacteria, legumes are capable of fixing atmospheric nitrogen, which when residues from the legumes decompose, enrich the soil content of nitrogen. Legume cover crops recycle other nutrients, thus reducing leaching losses that often occur in soils during the winter and spring seasons. In addition to these advantages, legume cover crops used with no-tillage corn provide a surface mulch which reduces soil erosion, slows evaporation of soil moisture, increases infiltration of rainfall, and increases soil …
Distorted Wave Born Approximation For Inelastic Collisions: Application To Electron Capture By Positrons From Hydrogen Atoms, Robin Shakeshaft, J. M. Wadehra
Distorted Wave Born Approximation For Inelastic Collisions: Application To Electron Capture By Positrons From Hydrogen Atoms, Robin Shakeshaft, J. M. Wadehra
Physics and Astronomy Faculty Research Publications
We have re-examined the distorted-wave Born approximation for inelastic collisions. We find that the distortion in the relative motion of the collision partners cannot be neglected even for high-energy ion-atom collisions. Furthermore, if the distortion in the relative motion is not treated exactly, post-prior discrepancies will occur. We have applied the distorted-wave Born approximation, with distortion included through first order, to ground-state-to-ground-state electron capture by positrons from hydrogen atoms. The results are presented in this paper. We have also examined the nonrelativistic asymptotic behavior of the cross section for electron capture from hydrogen by positrons incident with a speed v∼∞. …

Heavy Ion Beam Model For Radiobiology, Rose Ann Roth, Robert Katz
Heavy Ion Beam Model For Radiobiology, Rose Ann Roth, Robert Katz
Robert Katz Publications
An ad hoc model of energetic heavy ion beams, including secondary and tertiary particles, has been constructed for predicting radiobiological experiments. While the beam model is relatively primitive, it yields depth-dose and depth-radiobiological calculations in good agreement with experiment upstream of the Bragg peak. Beyond the peak, the model is somewhat coarse grained and seems to underestimate low-LET fragment production. These defects can be repaired at some cost in computer time. Presently a complete set of depth-dose and radiobiological results (RBE, OER, aerobic and hypoxic survival) is obtained in 4–8 min, for a single beam, at a cost of $10. …
Large Momentum Transfer Limit Of Some Matrix Elements, J. M. Wadehra, Larry Spruch
Large Momentum Transfer Limit Of Some Matrix Elements, J. M. Wadehra, Larry Spruch
Physics and Astronomy Faculty Research Publications
The matrix element εfi(K), or ε, that appears in the study of elastic and inelastic electron-atom scattering from an initial state i to a final state f in the first Born approximation depends explicitly on the momentum transfer ℏK⃗ . The uncertainty in the value of the calculated cross sections arises not only from the application of the Born approximation but also from the approximate nature of the wave functions used. For the 1 S1−2 P1 transition in helium, we present an analytic expression in terms of the 1 S1 and 2 P1 wave functions for the leading coefficient C1 …

All Computer Science and Engineering Research
We have developed a formal model of a database system that is unusual in that it has the ability to represent information about its own structure and to insure semantic consistency. The model distinguishes general laws from instances of events and objects, but many of its mechanisms serve both categories of information. The model form a substrate upon which an information structure appropriate to neonatology is being developed. Some example queries are shown and a design study for an associative memory suggested by the model is described briefly.

Effect Of Fish Size On Prey Size Selection In Gambusia Affinis, Wayne A. Wurtsbaugh, Joseph J. Cech Jr., James Compton
Effect Of Fish Size On Prey Size Selection In Gambusia Affinis, Wayne A. Wurtsbaugh, Joseph J. Cech Jr., James Compton
Watershed Sciences Faculty Publications
Food size selection of the mosquitofish , Gambusia affinis affinis. was measured in aquaria using juvenile stages of the mosquito, Clllex tarsalb;, as prey. Fish size varied from recently born fry to large adult females. Food size selection was positively correlated with fish size. Mosquitofish fry (6-8 111m standard length) attacked and ate primarily first and second instar larvae. Fry attacked larger instars, but attack success on these was low (0 - 50%). Fish larger than 20 mm attached primarily pupae and third and fourth instar larva. No first instar mosquitoes were eaten. Attack success for these fish was above …

Mass Marking Of Mosquitofish: Preliminary Results, Bruce Vondracek, Wayne A. Wurtsbaugh, Joseph J. Cech Jr.
Watershed Sciences Faculty Publications
Three marking techniques were tested to determine their applicability for mosquitofish. Tetracycline drugs and DC Ar administered in the diet successfully marked laboratory-cultured mosquitofish, but exposure to direct sunlight in outdoor tanks resulted in the rapid disappearance of the marks. Preliminary data on fluorescent marks from a polystyrene pigment in a melamine-sulfonamide-formaldehyde resin forced into the dermal ,tissue with compressed air are more promising.
A t an optimal deliver pressure of 7.3 m Hg (140 p.s.i.) and spraying time of 15 sec., marking percentage is maximized and fish mortality is minimized. Mark retention time was up to 80 days in …

Bela G. Fejer
Seasonally averaged quiet-day F region ionospheric E × B drift observations from the Millstone Hill, St. Santin, Arecibo, and Jicamarca incoherent scatter radars are used to produce a model of the middle and low-latitude electric field for solar minimum conditions. A function similar to an electrostatic potential is fitted to the data to provide model values continuous in latitude, longitude, time of day, and day of the year. This model is intended to serve as a reference standard for applications requiring global knowledge of the mean electric field or requiring information at some location removed from the observing radars. This …
Frequency-Dependent Conductivity In Nbse3, G. Gruner, L. C. Tippie, Jeff Sanny, W. G. Clark, N. P. Ong
Frequency-Dependent Conductivity In Nbse3, G. Gruner, L. C. Tippie, Jeff Sanny, W. G. Clark, N. P. Ong
Physics Faculty Works
The observation of a frequency-dependent conductivity (σ) and dielectric constant (ε) in NbSe3 is reported. In both charge-density-wave phases a strong frequency dependence and huge dielectric constant are observed below 100 MHz, with greatest effects observed at 42 K. The conductivity σ increases smoothly from the dc value to the high-frequency (f=100 MHz) limit; this increase is accompanied by the reduction of ε. A resistance-capacitance network model is suggested to account for the observed frequency dependence.
Sample Size Calculations And Optimal Followup Time In Health Services Research Using Utilization Rates, Paula Diehr
Sample Size Calculations And Optimal Followup Time In Health Services Research Using Utilization Rates, Paula Diehr
UW Biostatistics Working Paper Series
It is not always possible to estimate the sample sizes needed in health services research because special formulas are needed, and the necessary data may not be available to use in the formulas. We provide some useful formulas for the sample size required in comparing the means of two groups. These include the special case where the two groups are not of equal size either because one is known to have a higher variability or because one group has already been chosen and its size is thus fixed. We also explore the relationship of the mean to the standard deviation …

Hierarchical Analysis Of A Distributed Evaluator, Robert M. Keller, Gary Lindstrom
Hierarchical Analysis Of A Distributed Evaluator, Robert M. Keller, Gary Lindstrom
All HMC Faculty Publications and Research
We outline the analysis of a distributed evaluator for an applicative language FGL (Function Graph Language). Our goal is to show that the least fixed point semantics of FGL are faithfully implemented by the hardware evaluator envisioned in the Applicative Multi-Processor System AMPS. Included in the analysis are a formalization of demand-driven computation , the introduction of an intermediate graphic language IGL to aid in our proofs, and discussion of pragmatic issues involved in the AMPS machine language design.

The purpose of this Bulletin is to reconstruct a series of long run temperature and precipitation instrumental records for Maine (monthly means and accumulations). We hope that the data tables and graphs produced here will be of use to climatologists and other researchers and to Maine residents who are interested in the climatic history of the state. To aid in reconstruction, regional records were formed by grouping records from several geographical locations.
Much of the data reproduced here have been published elsewhere in a wide variety of publications. Some are found easily in libraries while others are not readily available. …
Development Of A System For Water Quality Analysis Using Particle Induced X-Ray Emission, James Albert Andrus
Development Of A System For Water Quality Analysis Using Particle Induced X-Ray Emission, James Albert Andrus
Masters Theses
Particle induced x-ray emission (PIXE) has been in use for several years at Western's accelerator laboratory. Its primary purpose has been to provide trace element analysis of various types of solid samples. The analysis of water samples has not been done because of problems involving target preparation for the accelerator. A process called vapor filtration, developed at Purdue University, allows adequate sample preparation for the accelerator. This process is being adapted for use here at WMU. When completely operational, this system will give the WMU accelerator program the additional capability of performing water quality analyses to concentrations of parts per …

Variations In The Depositional Environment Of The Lower Cincinnatian Kope Formation, Thomas K. Mahan
Variations In The Depositional Environment Of The Lower Cincinnatian Kope Formation, Thomas K. Mahan
Masters Theses
In northern Kentucky, the Upper Ordovician (Lower Cincinnatian) Kope Formation outcrops as a series of interbedded, laterally discontinuous limestone lenses and beds enclosed in a silty shale unit. Six stratigraphic sections within a 20-mile radius were sampled and measured and two of these were described in detail to characterize the variations in the environmental setting wherein the Kope Formation was deposited.
The shale lithology is homogeneous throughout this formation whereas the bioclastic limestones vary widely in faunal composition, texture, cross-sectional shape, and thickness. Apparently, the depositional style for the fine-grained, terrigenous sediment remained almost constant through Early Cincinnatian time, whereas …

Two series of complexes trans-{Co(LL')EDDA}('+) and trans-{Co(LL')DMEDDA}('+), LL' = Meen, 2-Mepn, udmeen, sdmeen, R-dmepn were prepared. EDDA was reacted with cobalt(II) carbonate and the resulting solution combined with the diamine of choice. For the DMEDDA complexes the ligand DMEDDA was first prepared by adding neutralized chloroacetic acid to sdmeen and precipitating out the ligand as the barium salt. The DMEDDA complexes were prepared by reacting the barium salt first with cobalt(II) sulfate and then with the diamines listed above except udmeen. The DMEDDA complexes with R-pn were also prepared. For both series the oxidation of the Co(II) to Co(III) was …

Analysis Of Differential Corrosion On High-Silicon Steel Laminations, Sompob Tingthanathikul
Masters Theses & Specialist Projects
The Cutler-Hammer plant in Bowling Green, Kentucky,manufactures laminated steel armatures for electrical starters (large relays) on which corrosion occurs only in some regions. The manufacturing process includes a heat treatment step from which the laminations emerge with a non-uniform surface appearance.
Laminations from corroded regions of an armature have red oxide (Fe203) on the edges, while the sides have a black coating of partly-burned cutting-machine oil residue. The purpose of the project was to investigate the mechanisms of this corrosion and why it does not occur uniformly and to suggest practical solutions for the plant.

A Five Year Water Research Plan For The State Of Arkansas, Robert E. Babcock
Arkansas Water Resources Center Technical Reports
The present economy and quality of life in Arkansas have largely been determined by our natural resources and the way they have been used. Likewise, insuring a sound economic future and a healthful environment in the state will depend on the efficiency and the wisdom with which nature's gifts are managed in the future. As the state's population grows and places new demands on finite resources, the need for effective resource management becomes increasingly critical. Often, a history of plenty can lead to the belated recognition of emerging resource problems. In Arkansas, such is the case with the state's water …
