A Photographic Study Of The Infrared Oh Airglow, G. C. Loos

Physics & Astronomy ETDs

OH airglow is due to the rotational-vibrational transitions of the hydroxyl radical. Previous efforts to find the airglow's emission height in the atmosphere are discussed. Photography of the infrared airglow with a fast 35mm camera and Eastman Kodak high speed infrared film is described and a method for triangulating emission heights by two station photography is explained. The techniques for reduction of film data to height measurements and velocity measurements are presented. Observations are reported concerning the frequency of occurrence of bright spots and other features on the OH background and the intensity of the airglow as a function of …

Rotationally Inelastic Molecular Scattering. Computational Tests Of Some Simple Solutions Of The Strong Coupling Problem, Thomas P. Tsien, Gregory A. Parker, Russell T. Pack

Faculty Publications

Partial cross sections (opacity functions) for rotational transitions in atom-diatom collisions are computed in the infinite-order sudden (IOS) approximation and compared with accurate close-coupling (CC) calculations. Agreement is good in the dominant coupling (small total angular momentum J) region. Simple methods for calculating integral inelastic cross sections are discussed, and it is found that accurate cross sections can often be computed very simply, even when large numbers of channels are coupled together, by using IOS or first-order sudden (FOS) approximations for small J and CC or exponential Born (EBDW) methods for large J.

Self‐Focusing Of Laser Light In The Isotropic Phase Of A Nematic Liquid Crystal, D.V.G.L.N. Rao, S. Jayaraman

Physics Faculty Publications

Self‐focusing of ruby laser light is studied as a function of sample length and temperature in the isotropic phase of nematic liquid‐crystal MBBA. The critical power for self‐focusing, 0.36 kW, observed near the phase transition temperature is a factor of 20 times less than that for CS₂. The corresponding nonlinear index 4.4 × 10⁻¹⁰ esu is the largest value known so far for any material.

The Construction Of Two Prototype Multi-Storey Air-Supported Buildings, Jens G. Pohl, James Montero

Collaborative Agent Design (CAD) Research Center

To treat a multi-storey building as a large, inflatable container forces the architect to consider design and construction criteria foreign to the building industry at large. While satisfactory progress has been made in the development of theoretical solutions for problems dealing with the structural and planning implications of a hyperbaric building environment, the time has come to consider practical issues.

This paper discusses the design, construction and operation of two prototype, multi-storey, air-supported buildings. The first building was completed in November, 1972 at the School of Building, University of New South Wales, Australia, and the second building was completed in …

Dissociative Attachment From The O2 (A1 Δ G) State, P.D. Burrow

Paul Burrow Publications

The dissociative attachment cross section for production of O^- by electron impact on the metastable O₂ (a¹ Δ _g) state is studied. The cross section is found to be 4.6 ± 1.3 × 10^-18 cm² at its maximum. From the measured energy dependence, we infer that the dissociative attachment process takes place through the O^2̅ (² П_u) state as in the case of O^- production from the O₂ ground state. The information thus obtained is used to estimate the portion of the cross section for excitation of the …

Decompositions Of Modules And Matrices, Thomas Shores, Roger Wiegand

Department of Mathematics: Faculty Publications

A canonical form for a module M over a commutative ring R is a decomposition M ≈ R/I₁ Ο … Ο R/I_n, where the I_j are ideals of R and 1₁ ≤ . . . ≤ I_n. A complete structure theory is developed for those rings for which every finitely generated module has a canonical form. The (possibly larger) class of rings, for which every finitely generated module is a direct sum of cyclics, is also considered, and partial results are obtained for rings with fewer than 2^{c …}

Social Costs And Benefits Of Water Resources Construction, Rabel J. Burdge, K. Sue Johnson

KWRRI Research Reports

This report analyzes and describes the process of relocating individuals and families who must move due to reservoir construction in Kentucky utilizing data collected in previous research. These data come from four separate studies: a study of community attitudes toward reservoir construction (Johnson county where the Paintsville reservoir is to be constructed), interviews with people who are slated for relocation when the Taylorsville reservoir is constructed, and two sets of interviews with people who have already been relocated due to reservoir construction (Cave Run and Carr Fork).

Psychological, social, economic and material costs and benefits associated with forced relocation are …

A Study Of Water-Soluble Inhibitory Compounds (Algicides) Produced By Fresh-Water Algae, Denny O. Harris, Manhar C. Parekh

KWRRI Research Reports

A complex system of growth inhibitors was observed in the green algae (Volvocaceae). Inhibitors were found in the culture filtrates of some genera which limit their own growth (autoinhibitors) while others in the family produce substances which check the growth of other genera (heteroinhibitors). These inhibitors were destroyed by autoclaving. It was decided that Pandorina morum, which produced the strongest inhibitor and Volvox tertius, the most sensitive to the inhibitor would make an excellent model system for a study of the chemical and physical properties of these naturally occurring algicides. The algicide could be removed from actively growing cultures about …

A Detailed Investigation Of The Sociological, Economic, And Ecological Aspects Of Proposed Reservoir Sites In The Salt River Basin Of Kentucky, Stuart E. Neff, Louis A. Krumholz, John R. Baker, Daryl E. Jennings, Andrew C. Miller, Jerry S. Parsons, Vincent H. Resh, David S. White

KWRRI Research Reports

Samples of water, bottom fauna, and fishes were collected from 66 stations in the Salt River and one of its principal tributaries, the Beech Fork and its tributary, the Chaplin River, Kentucky. Precipitation ranged from 38.86 inches (1969) to 58.04 inches (1970), an increase of nearly 50 percent with marked fluctuations in discharge. Intensive comparisons of phosphates, sulfates, specific conductance, total alkalinity, total hardness, and turbidity showed the streams to be relatively clean and healthy. Nearly 300 different kinds of benthic organisms and other macroinvertebrates have been collected and identified from the basin. Detailed studies of caddisflies and stream drift …

Mathematical Simulation Of Temperatures In Deep Impoundments: Verification Tests Of The Water Resources Engineers, Inc. Model - Horsetooth And Flaming Gorge Reservoirs, Engineering And Research Center, Bureau Of Reclamation

All U.S. Government Documents (Utah Regional Depository)

Successful use of predictive mathematical models requires verification of the accuracy of the models by applying them to existing situations where the prediction can be compared with reality. A Corps of Engineers' modification of a deep reservoir thermal stratification model developed by Water Resources Engineers, Inc., was applied to two existing Bureau of Reclamation reservoirs for verification. Diffusion coefficients used for the Corps' Detroit Reservoir were found to apply to Horsetooth Reservoir in Colorado, for which very good computer input data were available. The Detroit diffusion coefficients gave a reasonable simulation of Flaming Gorge Reservoir in Wyoming and Utah, which …

Crop Depredations By Waterfowl In Wisconsin, Richard A. Hunt, James G. Bell

Bird Control Seminars Proceedings

On December 5, 1965 the Governor of Wisconsin signed into law a statute permitting claims against the State for damages to crops by wild geese and ducks. This law had been rushed through the legislature in the wake of a rash of crop depredation complaints caused by Canada Geese in their off-refuge feeding flights from the Horicon National Wildlife Refuge. This paper reviews our experiences with waterfowl depredations in the development of a cooperative program by State and Federal wildlife agencies that has held a potentially serious wildlife problem to a minimum of financial losses and public relations concern.

New Materials And Methods, Jerome F. Besser

Bird Control Seminars Proceedings

I have several short thoughts I would like to share with you. This conference has presented few new methods, but most of you do not need a new method to solve many of the problems you encounter. Some of the old methods, if used with much enthusiasm, will work just as well. One reason that few new methods are being developed is the time taken for the development of old methods. I would like to leave you with one thought, and I think this is particularly urgent in the chemical area. We have been trying to develop chemical agents for …

Npca Education Committee, James Steckel

Bird Control Seminars Proceedings

The major thrust of the Education Committee results from the rather urgent need to implement interesting programs in which supervisors may train for examination and certification under the qualifications of the pesticide act. While it is not easy at this time to determine what certification is going to be, what supervisors are going to be involved, what kind of examination they are going to have to take, and how the state is going to interpret all of this, we therefore cannot be specific. The wheels are grinding away, and as you know, the timetable is winding down; and we may …

Tests Of A Potential Method For Decoying Starlings To Bait Stations, Robert E. Williams, Robert G. Schwab

Bird Control Seminars Proceedings

The costs of existing Starling control programs prompted the design and test of an alternative method for removing significant numbers of Starlings from heavily damaged areas. The procedure involved the placement of taxidermically prepared adult Starling skins on and near bait stations, accompanied in some cases by broadcasts of recorded Starling vocalizations. Previous studies had indicated that bait stations unaccompanied by live Starling decoys were not acceptable to the birds. Although non-toxic baits were used during these tests to determine the attractability of the stations, ultimate substitution of chemically treated toxic baits was envisioned.

Radiotelemetry For Studying Problem Birds, Olin E. Bray

Bird Control Seminars Proceedings

Bird problems are much easier to solve if information is available on the behavior of the birds involved. Banding, color-marking, and visual observations have provided only general information on the behavior of problem birds. In order to continuously monitor the activities of birds causing problems, personnel in our Bioelectronics Unit and I developed a radiotelemetry system. A. Lawrence Kolz, George W. Corner, Erwin W. Pearson, and Richard E. Johnson of the Bioelectronics Unit provided the knowledge of electronics and many days of tedious work necessary to develop this system.

Fao Quelea Research In Africa, Jeffrey J. Jackson

Bird Control Seminars Proceedings

Large scale grain growing schemes are developing rapidly in Africa and the importance of birds as pests becomes more evident each year. Although the potential production of cereals is quite high in some parts of Africa, effective methods for protecting the new schemes from bird damage will have to be developed if their food raising potential is to be realized. The best known of the avian pests of cereals in Africa is Quelea quelea. In addition to their importance as pests their notoriety is due to their intensely gregarious nature. The cloudlike feeding swarms and dense nesting colonies with millions …

Local Fall Movements Of The Red-Winged Blackbird In Central New York, Noel J. Cutright

Bird Control Seminars Proceedings

Studies into the post-breeding season activities of the Red-winged Blackbird (Agelaius phoeniceus) recently have received greater attention. The United States Fish and Wildlife Service began a massive study involving the finding of winter concentrations of blackbirds and the marking of individuals. Meanley (1965, 1971), the most conspicuous name in the literature involved in this work, has recently published observations on the roosting behavior of the Redwing in southern United States. This wave of interest in blackbirds also is present in New York. Growers in the Finger Lakes Region have become quite concerned with the extent of damage to their corn. …

Avitrol, Allen Stickley

Bird Control Seminars Proceedings

Now that Avitrol has been registered for use on field corn, the next step is to get the chemical registered for use on other crops. Two of the most important are sweet corn and sunflowers. Accordingly, personnel at the Bureas of Sport Fisheries and Wildlife, Sandusky, Ohio field station planted 16 experimental plots each in Sandusky and Ottawa Counties in Ohio this past summer to gather data on the efficacy of Avitrol when used on sweet corn and sunflowers. Of the 16 plots in each county, eight were sunflower plots, eight were corn plots. We applied Avitrol to four of …

A Bibliography On The Red-Winged Blackbird, Noel J. Cutright

Bird Control Seminars Proceedings

Following the completion of my doctoral dissertation on the Red-winged Blackbird, I decided to compile a bibliography on the species. This bibliography updates and expands the selected bibliography on Redwings prepared by Mealey and Mitchell in 1966. No effort was made to list the many progress and final reports on various aspects of blackbird research issued by the Bureau of Sport Fisheries and Wildlife. Literature citations follow the Style used in The Journal of Wildlife Management.

Legal Requirements And Status Of Protected Bird Species, Richard N. Smith

Bird Control Seminars Proceedings

Migratory birds found in North America are protected by the Migratory Bird Treaty Act, which implements migratory bird conventions between the United States and Great Britain and the United States and Mexico. An amendment to the Act in 1972 placed all migratory bird species except for exotic species such as Starlings, Pigeons, and House Sparrows in a protected status. There are sections within the Act that allow for the issuance of permits to take protected species. Those sections that are of the most concern to the pest control operator deal with certain blackbird species that cause agri- cultural crop damage …

Insurance, Mark Weisburger

Bird Control Seminars Proceedings

We have been working with exterminators on the insurance problems for thirty-five or so years. Recently PCO’s have been doing much in the way of bird control. There does not seem to be anyone that we know of who does strictly bird control insurance, so our group always ties it in with our pest control. I feel that nothing touches everyone so regularly, with the exception of the federal government, as your insurance premiums. I would like to discuss with you the causes and results of accidents and how they can effect insurance premiums.

Bird Control In Milwaukee : A Case History, Laverne A. Penn

Bird Control Seminars Proceedings

In planning a city-wide pigeon control program, many problems must be considered to conduct such a program safely and efficiently. The City of Milwaukee Health Department has been engaged in some degree of nuisance bird control activity for more than thirty years. Early attempts at bird control consisted of using fireworks, rubber snakes, paper mache owls, and other devices to prevent starling roosting. All met with very limited success and were eventually abandoned. Until the post World War II period, Milwaukee, like most large cities, was plagued by an abundance of homeless pigeons. Pigeons were abundant on downtown streets, commercial …

Pricing, John R. Beck

Bird Control Seminars Proceedings

I would like to make six points concerning pricing. Number one, there is a great deal of time required in observation. Secondly, there is no such thing as a cheap bird job. Third point: there is no job that is routine. The fourth point: observations are necessary to delineate the species, the type of environment, human interference, the type of job it is going to be, and the needs of that job. The fifth point: bird work cannot be assigned to a person who does not appreciate the need for technical compliance with laws and regulations. Number six: do not …

Cowbird Trapping And The Kirtland’S Warbler, Richard O. Winters

Bird Control Seminars Proceedings

The 1971 census of the Kirtland’s Warbler taken on the warblers nesting grounds in North Central Michigan revealed that the population of this species had dropped to an all-time low of 201 singing males, as compared to 502 in 1961, a drop of some 60 percent in ten years. Breeding birds, furthermore, once found nesting in as many as nine counties during one nesting season returned to nest in only five counties in 1972, at which time the census indicated that the warbler population was remaining temporarily stable at approximately 200 singing males. Since the sex ratio of this species …
