The Potential Energy Surface Of (Nh3)2, Z. Latajka, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

Ab initio calculations at the SCF and correlated levels are carried out to characterize the potential energy surface of the NH₃ dimer. The two basis sets used are 4‐31G∗ and a larger one containing two sets of d‐functions on N centers, 6‐31G∗∗ (1p, 2d). The only minimum occurring on the surface is a cyclic C_2h structure in which the two H‐bonding protons are displaced 42° from the N‐‐N axis. The surface contains a very shallow valley along the direction leading from this geometry to a single linear H bond although …

Correction Of The Basis Set Superposition Error In Scf And Mp2 Interaction Energies. The Water Dimer, M. M. Szczesniak, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

There has been some discussion concerning whether basis set superposition error is more correctly evaluated using the full set of ghost orbitals of the partner molecule or some subset thereof. A formal treatment is presented, arguing that the full set is required at the Møller–Plesset level. Numerical support for this position is provided by calculation of the interaction energy between a pair of water molecules, using a series of moderate sized basis sets ranging from 6‐31G∗∗ to the [432/21] contraction suggested by Clementi and Habitz. These energies, at both the SCF and MP2 levels, behave erratically with respect to changes …

Factors Affecting Anion Movement And Retention In Four Forest Soils, D. W. Johnson, D. W. Cole, H. Van Miegroet, F. W. Horng

Watershed Sciences Faculty Publications

Three hypotheses concerning the movement and retention of anions in forest soils were tested in a series of laboratory and field studies on two Tennessee Ultisols with mixed deciduous forest cover and two Washington Inceptisols, one with deciduous (red alder Alnus rubra Bong.) and one with coniferous [Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco] forest cover. The first hypothesis, that sulfate and phosphate retention was related to adsorption to free Fe and Al oxides, which were in turn related to soil parent material and degree of weathering, was not supported by results of laboratory and field studies. The young, relatively unweathered Washington …

Water Quality Management Studies For Water Resources Development In The Bear River Basin, Darwin L. Sorensen, Craig Caupp, William J. Grenney, Steve Eberl, Jay J. Messer, Phillip Ludvigsen, Charles W. Ariss

Reports

Summary: The quality of water that develops in the proposed reservoirs of the Upper Bear River Storage Project will determine the possible uses of the water. Previous studies of water quality in the Bear River and its tributaries have reported water quality problems relating to nitrate ion, sanitary indicator bacteria, suspended solids, and phosphorus concentrations. Most point sources of water pollution inthe basin have been eliminated or improved in quality, but nonpoint sources of pollution continue to degrade the quality of the Bear River. Concentrations of phosphours have been sufficiently high to encourage dense algal growth and create eutrophic conditions …

Economic Evaluation Of Conservation Concepts For Municipal Water Systems, Trevor C. Hughes, Rangesan Narayanan, Mac Mckee, A. Bruce Bishop, Robert Leconte, Sumani Al-Hassan

Reports

Five concepts for conservation of municipal water supply are analyzed from an economic efficiency perspectice. They include: 1) seasonal pricing (for reduction of peak period water use), 2) dual water systems (separate high quality drinking water and untreated outdoor irrigation systems), 3) imported water transmission facility capacity optimization, 4) flow restricting devices, and 5) short-term rationing concepts. Optimization models, including generalized model generators, were developed for analysis of the first three concepts and demonstrated by applications to cities in Utah. The flow restricting device and short-term rationsing concept analyses applied approaches taken from the literature to example sites in Utah. …

Water Quality Management In Utah Mountain Watersheds, Keith R. Kimball, E. Joe Middlebrooks

Reports

What Quality Management in Utah Mountain Streams: Several years of thorough monitoring of water quality parameters in Little Cottonwood Creek in Salt Lake County, Utah, measured the natural levels of the major water constituents, spotted significant (largely nonpoint) pollution sources, identified the pollutants deserving primary attention, and suggested the approaches to land and water management for pollution control in a mountain watershed used primarily for recreation purposes. Bacterial pollution is greater at night than during the day, on weekends than on week days, and in the summer than in the winter. Mineral content is of natural origin and largely explained …

Expected Effects Of In-Lake Dikes On Water Levels And Quality In The Farmington Bay And The East Shore Areas Of The Great Salt Lake, Utah (Executive Summary), Duane G. Chadwick, J. Paul Riley, Alberta J. Seierstad, Darwin L. Sorensen, Norman E. Stauffer

Reports

Introduction: The Great Salt Lake is a terminal lake and as such is one of the major inland bodies of salt water in the world, and the largest lake of brine in the western hemisphere. Its unique features, including its mineral rich waters and interesting shores and islands, make it appealing to both industry and vacationers. Until recently, some of the great waterfowl sanctuaries in the U.S. existed along the easterly and northerly shores of the lake. However, during the past three years record breaking inflow volumes and lower than normal evaporation rates have caused an unprecidented rate of rise …

Long Term Effects Of Radiation And Combined Modalities On Mouse Lung, David P. Penney, Paul Van Houtte, Dietmar W. Siemann, Wayne A. Rosenkrans Jr., Philip Rubin, Robert A. Cooper Jr.

Scanning Electron Microscopy

The lung appears to be the major dose-limiting organ in radiation of the thorax. Early responses (<1 week) involve the type II pneumocyte and increased surfactant biosynthesis and secretion. Later changes, which appear to be related to the surfactant response, lead to classical radiation pneumonitis, which is often fatal. Animals which survive radiation pneumonitis develop progressive fibrosis, a late-appearing response, which reduces compliance and available air space, and is usually fatal. This study centers on the fine structural changes in the lungs of LAF₁ mice, 63 weeks following various radiation exposures (5-13 Gy). Doses which are subthreshold in evoking surfactant and pneumonitic responses precipitate fibrosis and atelectasis by 63 weeks, and involve type II pneumocyte sloughing and degeneration. Of the two major deterrents to lung irradiation (pneumonitis and fibrosis), these results suggest that fibrosis always follows pneumonitis, but pneumonitis is not a necessary preliminary step to fibrosis. Bleomycin elicits several morphological alterations characteristic of radiation, and, when combined with the latter, appears to exacerbate radiation effects.

Visible And Invisible Women In Land-Grant Colleges, 1890-1940, Alison Comish Thorne

Faculty Honor Lectures

The role and status of women in land-grant colleges has not really been studied. As many of these institutions have approached their centennials and have reflected on their past achievements, the lack of research about women faculty, women students, women staff, and faculty wives has been astounding. In part, our misperceptions or ignorance concerning women in this institutional setting is understandable. Like many women in other historical milieus, women at land-grant institutions have been invisible. Because they were rarely administrators, because they composed such a small part of the faculty, and often because of the discipline in which they taught, …

Vole Control In The Eastern United States, Richard M. Poche, Robert Sharp

Wildlife Damage Management Conference

The meadow vole (Microtus pennsylvanicus) and pine vole (M. pinetorum) are major pests in fruit orchards in the eastern U.S. These species damage trees by gnawing the bark or root systems during the winter months, thus, reducing the fruit yield, or in many cases actually killing the trees. Orchard owners generally use an integrated pest management approach involving a combination of methods: (1) cultural practices such as reducing favorable vole habitat, thereby, limiting the carrying capacity, (2) mechanical control through the use of tree guards or trapping techniques, and (3) the use of rodenticides, both acute …

Dispersal Of A Heron-Egret Rookery, Douglas I. Hall

Wildlife Damage Management Conference

A rookery composed of an estimated 10,000 herons and egrets (family: Ardeidae) located in Van Buren, Crawford County, Arkansas was successfully dispersed in the Spring of 1983. A diversified scaring program was planned and initiated prior to the onset of courtship display and nest building. The roost relocation was subsequently followed by habitat alteration procedures to make the 5-acre stand of primarily Eastern redcedar (Juniperus virginiana) unattractive as a future roosting site. Although no nesting occurred at the site in 1983, the lack of an early scaring program in the Spring of 1984 resulted in the uncleared …

Wildlife Damage Control And The Wildlife Society, Thomas M. Franklin

Wildlife Damage Management Conference

Wildlife damage control is recognized by The Wildlife Society as an essential and responsible segment of the wildlife profession. At least since 1959, Society committees have addressed elements of wildlife damage control (although wildlife damage control was not always the specific term used).

The Wildlife Society Council first approved an "Animal Damage Control" position statement in 1968. In March 1985, Council updated and renamed it "Wildlife Damage Control" to emphasize our positive approach to this important segment of wildlife management. The official position statement was published in The Wildlifer (May-June 1985) and is reprinted below.

The Effects Of Canada Goose Grazing On Winter Wheat: An Experimental Approach, Hubert A. Allen Jr., David Sammons, Russell Brinsfield, Roland Limpert

Wildlife Damage Management Conference

The effects of grazing winter wheat (Triticum aestivum) by Canada geese (Branta canadensis) was assessed in 3 fields during 2 years of experimentation at the Wye Research and Education Center, Queenstown, Maryland. Randomly placed wire enclosures prevented goose grazing on 11.1 m sq. control plots. Grazed plots were marked in each field soon after the geese migrated in March. Grazed plots had consistently lower yields than ungrazed plots with mean differences ranging from 0-13%. The differences were related to the intensity of grazing. Other parameters, including mean weight per seed, mean number of seeds per spike, …

What You Wanted To Know About All You Ever Heard Concerning Snake Repellents, Gary J. San Julian, David K. Woodward

Wildlife Damage Management Conference

Have you ever heard about a way to keep snakes away from your house? Many people in North Carolina have been told by their elders of various ways to repel snakes. When we first started working on this problem in North Carolina, we were amazed at the number of "home remedies" that people believed would protect their property from snakes; and we began to keep a record of these remedies. In 1981, a grant from the Pesticide Impact Assessment Program allowed us to begin to test some of these remedies to determine their value.

Birds In Hangars- A Messy Problem, Albert E. Bivings Iv

Wildlife Damage Management Conference

Pest birds in hangars and similar man-made structures pose specific health hazards as well as nuisance and corrosion problems. While lethal control or a scaring program may be the best technique for some locations, neither address the long-term problem of the basic attractiveness of these structures to birds. The best long-term solution usually is to exclude the birds with permanently installed plastic or nylon netting. Several methods to accomplish this are discussed.
