History Of Animal Experimentation Control In The U.K., Judith E. Hampson

Laws and Legislation Collection

The legislative control of the use of animals in experiments in the UK lies in the Cruelty to Animals Act of 1876. Animal Welfare groups and individuals in Britain have pressed for reform of this law almost since its inception 105 years ago, and the British government has recently agreed to bring this legislation up to date. Any new or amended legislation could have far-reaching implications, both for laboratory animal welfare and upon the scientific community and is therefore of considerable importance both in this country and overseas. No proper appreciation of the problem would be possible without reference to …

Selected Biological Characteristics Of Streams In The Southeastern Uinta Basin, Utah And Colorado, United States Geological Survey

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

Biological sampling was carried out during 1976-78 in five streams in the southeastern Uinta Basin, Utah and Colorado, in order to provide baseline water-quality data for an area of potential oil-shale development. The biological activity in the streams sampled generally is limited by physical factors more so than by chemical constituents and plant nutrients. Characteristics of streamflow, such as high turbidity, fluctuating water levels, and moderate to high salinity, limit production of flora and fauna biomass.

Fisheries Report No 45 - The Short Term Effects Of Brush Harvesting On The Kwongan Vegetation At Eneabba, Western Australia, E. A. Griffin, A. J. M. Hopkins

Fisheries Research Reports

Areas of the kwongan vegetation south of Eneabba are currently being harvested to provide brush for rehabilitation after mining. Because of the botanical importance of the Eneabba kwongan, a study of the effects of the harvesting was initiated. Three areas with different harvest histories were sampled using quadrats paired across cut/uncut boundaries. Floristic and structural differences between quadrats and between areas were assessed. The store of seed in uncut vegetation was measured.

There was a loss of species as a result of harvesting, at least in the short-term. Many species regenerated by resprouting from buds in damaged stems or in …

Report No 47 - 1980 Review Of Rainfall And Wetlands In The South-West Of Western Australia, J. A.K. Lane, D. R. Munro

Fisheries Research Reports

An account is given of the biological principles involved in decisions concerning duck-shooting seasons in the south-west of Western Australia.

The conditions for waterfowl which prevailed during 1980 are described through the use of rainfall statistics and data obtained from the Department's wetland monitoring programme.

1980 was the fifth consecutive year of below-average rainfall in all five Meteorological Districts of the south-west. 1976 to 1980 was thus' the south-west's driest five-year period since 1913 at least.

Low rainfall during 1980 resulted in a further decline in the condition of wetlands throughout most of the inland south-west, Few gauged wetlands increased …

The Physical And Chemical Limnology Of Lake Mcconaughy With Reference To Fisheries Management, Melvin W. Taylor, Kit M. Hams

Nebraska Game and Parks Commission: Publications

Lake McConaughy is an important fishery resource of the state of Nebraska. The estimated fishing pressure in 1975 as determined from a postal creel census was 175,872 angler days (Morris 1977). This estimate is inflated compared to an on-site creel census conducted in 1977-78 which showed a total of 69,500 fishing trips annually (Madsen 1980). Not all fishermen were contacted so this estimate is undoubtedly too low. Regardless of which figure is accepted, the reservoir provides many man-days of fishing opportunity. Conservation and management of the fishery resource is necessary to maintain and/or improve its quality,

A Laboratory Evaluation Of Leachate From The Jim Bridger Power Plant Scrubber Wastes, V. Dean Adams, Mary E. Pitts, Megan J. Dyer

Reports

Introduction: Scrubber wastes obtained in an affort to limit air pollution generated by coal-fired pwoer plants may contribute to another possible sources of pollution. To date, scrubber wastse have been in a liquid phase which causes disposal problems partially due to the liquid characteristics. The use of solid scrubber wastes and the land deposition of such wastes is proposed. The feasibility of solid scrubber wastes disposal in landfills is under question. The primary area of concern is the effect that water percolation through such wastes would have on groundwater quality parameters. Contamination could result either as precipitation travels downward through …

Glow Discharge Polymerization., H. Yasuda

Chemistry Faculty Research & Creative Works

In this review-paper the author summarizes some important aspects of ″polymer formation″ in the glow discharge polymerization or plasma polymerization, rather than presenting a bibliographical review of work. It is shown that glow discharge polymerization can be visualized as a process consisting of three discharge processes. These are (1) controlled discharge of monomer, (2) electric discharge (glow discharge), and (3) glow discharge polymerization of the monomer. Before the electric discharge is initiated, a steady-state flow of the monomer is generally established. During this controlled discharge of the monomer (without electric discharge), adsorption of the monomer onto the solid surfaces in …

Design Considerations In The Use Of Glauber Salt For Energy Storage, Duane G. Chadwick, Kim H. Sherwood

Reports

Various design concepts for the utilization of the latent heat of Glauber salt at temperatues between 25 degrees C and 50 degrees C were studied. Consideration was given to system economics and what particular heat storage system if perfected would be most cost effective. The problems of limited crystal size and heat transfer into and out of salt crystals is discussed. Crystal size is affected by the degree of agitation the salt solution experiences during the salt cooling process. Consequently, crystal size was moderated in a favorable way by introducing air bubbles at the bottom of the salt container. As …

Study Of Iron In Magnetotactic Bacteria, Richard B. Frankel, Richard P. Blakemore

Physics

Bacteria have recently been discovered directing their movements by sensing the earth's magnetic field. They contain arrays of crystals of lodestone or magnetite which they synthesize from iron in the ocean. The discovery of the same type of crystals in the abdomens of honey bees and the brains of homing pigeons suggests that nature is not oblivious to the earth's magnetic field. The biological mechanism for sensing magnetic fields has never been determined. These bacteria are capable of biologically synthesizing highly purified single domain magnets that would be very expensive to produce chemically.

The Gloom Gets Doomier, David A. Summers

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This paper reviews the likely sources of energy in the year 1990. Economic conditions, difficult to forecast, affect short-term consumption, while technological breakthroughs, equally impossible to predict, will control long-term production of energy. For the ten-year period, however, commitments to construction, or feasibility studies, must already be in hand. This allows a prediction of the energy supply for that year, and such a prediction is made. Because this indicates that only about 1 percent growth in supply can occur over this time period, against a requirement for at least 2 percent, the forecast is doomier than it was in earlier …

Energetics Of Moving Magnetic Waves, Tom Day

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Magnetism has had a certain and specific appeal of human inquiry for at least the past forty centuries of civilization. History is full of adventures into the unknowns about this natural phenomenon. Recent findings hint of a hidden physical world concerning magnetism which prompts continued exploration. Curvilinear motion on a continuous basis can be detected within a magnetic field consisting of large, slow moving spiral wave patterns. This paper presents a procedure whereby the reader can establish his or her own findings about the power and energy of magnetic conductance. Avenues of basic research are explored and discussed.

The Economics Of Metals Recovery From Power Plant Fly Ash Via The Ames Hichlor Process, S. J. Weiss, G. Burnet, C. Y. Chang

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The disposal of potentially hazardous coal wastes is becoming a significant problem for the payer industry. The Ames HiChlor process, which utilizes paver plant fly ash as a source of aluminun, is proposed as a method of coal waste utilization. In the HiChlor process fly ash is chlorinated in the presence of a carbonaceous reduct ant at 700 to 900°C to produce alumnum chloride and titaniun tetrachloride as salable products. An economic analysis for a plant vhich would process 6,000 tons per day of fly ash is presented. Conditions under which the proposed process will prove profitable are discussed.

Epizootic Of Coccidiosis In Free-Flying Lesser Scaup, R. M. Windingstad, M. E. Mcdonald, L. N. Locke, S. M. Kerr, J. A. Sinn

Nebraska Game and Parks Commission: Staff Research Publications

A coccidiosis epizootic has occurred in lesser scaup (Aythsa affinis) at Bluestem Reservoir in eastern Nebraska during the spring in each of three recent years: 1976-1978. Losses peaked during the period from mid-March through April. As much as 29 % of the peak population of scaup using the reservoir died. Necropsies of 72 of the nearly 1390 scaup that died revealed destruction and sloughing of the intestinal mucosa and associated hemorrhaging. Fibrinonecrotic cores were frequently found in the intestinal lumens. Scrapings from the intestinal mucosal contained massive numbers of oocysts of the coccidian Eimeria aythyae. This is …

Feasibility Of Quasi-Random Band Model In Evaluating Atmospheric Radiance, Navin Mirakhur

Mechanical & Aerospace Engineering Theses & Dissertations

The use of the quasi-random band model in evaluating the upwelling atmospheric radiation is investigated. The spectral transmittance and total band absorptance are evaluated for selected molecular bands by using the line-by-line model, quasi-random band model, exponential sum fit method, and empirical correlations, and these are compared with the available experimental results. The atmospheric transmittance and up­ welling radiance have been calculated by using the line-by-line and quasi-random models and are compared with the results of an existing program called LOWTRAN. The results obtained by the exponential sum fit and empirical relations are not in good agreement with experimental results …
