Inbreeding In Rainbow Trout (Salmo Gairdneri): Analysis Of Lethal Temperature Tolerence, Jospeh L. Mangiardi

Electronic Theses and Dissertations

Inbreeding in rainbow trout (Salmo gairdneri) was evaluated in relation to an altered environment (upper lethal temperature 29 C), at four levels of inbreeding. At each level of inbreeding mean time to death for inbred, female-outbred half-sib, male-outbred half-sib and outbred families were evaluated. In all cases inbreds were less resistant to lethal temperature than were respective outbred families. Analysis of variance 9Snedecor’s F) and multiple range analysis (Tukey’s “w” procedure) provided inference limitations. Inbred fish were 82% less resistant to lethal temperature as comared to the respective outbred family at 50% inbreeding and 19% less resistant at 25% inbreeding. …

Special Reflectance Of Hydrophytes, Robert G. Best

Electronic Theses and Dissertations

Identification of hydrophytes will improve the delineation and classification of wetlands on remotely sensed imagery. Spectral reflectance measurements of 10 species of hydrophytes were made with an Exotach radiometer during three phenological stages, flowering and early seed, senescence, and early emergent. Reflectance data were analyzed to determine significant (≥.95) reflectance differences between species in each of four spectral regions during each phenological stage. Eight species had significantly (≥.95) different reflectances during the flower and early seed stage. Only one species could not be spectrally separated during at least one phenological stage. The results indicate that films sensitive to both visible …

Modelling The Influence Of Eutrophication On The Coldwater Fishery Habitat Of Lake Mcconaughy, A "Two-Story" Reservoir, Melvin W. Taylor

Nebraska Game and Parks Commission: Publications

The lifespan of the existing coldwater habitat in Lake McConaughy is unknown, To promulgate effective management and regulatory strategies, a method of predicting this lifespan was needed, Ideally, this procedure should also provide potential management philosophies that would retard eutrophication, The LAKSCI computerized simulation model of Systems Control, Inc, was modified to assist in solving this problem, Data for model input were collected from August 1976 to August 1978. When calibrated the model proved satisfactory for predicting water level and temperatures, but unsatisfactory in prediction of water chemistry without additional data and refinement,

Contour Cultivation : Cheap Erosion Control, T R. Negus, B. Barrett

Journal of the Department of Agriculture, Western Australia, Series 4

Although the benefits of contour cultivation are well recognised, it makes cultivation more difficult, particularly if the paddock is split by contour banks and grassed waterways. However, a comparison east of Pingelly indicates that contour cultivation is little more expensive or time-consuming than ordinary cultivation.

Economic Feasibility Of Ethanol, Methanol And Alcohol-Gasoline Blends As Alternatives To Gasoline As Motor Fuels, Marjorie Diane Pettypool

A Preliminary Cost-Benefit Analysis Of The Proposed St. Thomas-St. John Sand Mining Project, Random Dubois

Marine Affairs Theses and Major Papers

A territorial ban on beach and sand removal in the U. S. Virgin Islands has resulted in a search for alternative sources. Insecure extra-territorial reserves and high shipping costs have made sand importation prohibitive. Recent surveys conducted in 1977 by the U. S. Geological Survey identified several nearshore sources of aggregate adjacent to the island of St. Thomas. In a 1978 workshop jointly conducted by the Government of the Virgin Islands and the National Oceanic and Atmospheric Administration various alternatives were presented for sand extraction. Two alternatives are examined using a cost benefit approach.

Low Btu Producer Gas -- A Fuel Of The Past And A Fuel Of The Future, Lee Carter

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

A prime purpose of this paper is to give conscious emphasis to an important type of coal gasification, one that does not demand hundreds of millions of dollars to launch an experimental program but instead is essentially ready to use after a reasonable and straightforward engineering check-out of the local coal sources and the prospective gas demand.

That type of coal gasification results in low Btu producer gas. This paper deals with its history, its technology and its economics. In the light of that information, the future of low Btu producer gas in America then is assessed.

Effective Utilization Of Energy From Biomass Residues In Agricultural Applications, Harry W. Parker

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

Biomass is one of the more attractive alternative energy sources. Use of existing biomass residues within the farm and ranch economy can be accomplished with a minimum of organizational problems since the producer, processor, and consumer may be the same person or organization. The major task is to provide potential agricultural biomass users with accurate cost estimates for the energy made available from the biomass, and contemporary technology for its utilization.

Specific examples are given with regard to powering irrigation well engines with cotton gin trash via a producer gas generator, and conversion of harvested mesquite wood to digestible energy …

New Concept In Louver Blade Design Reduces Energy Losses, Peggy Kitchen, R. David Moore

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

A new louver blade design, developed through extensive wind tunnel tests, employs an airfoil shape with excellent aerodynamic characteristics. Stressed-skin construction adds strength and rigidity permitting the use of longer blades and the elimination of unnecessary frame sections. Lever arms and linkage rods are placed out of the airstream, further reducing resistance to airflow. Louvers and dampers employing this design will have a pressure drop of from 1/4 to 1/10 that of units of traditional design.

Comparison Of Stirred And Immobilized Cell Reactors For Ethanol Production, Oliver C. Sitton, J. L. Gaddy

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

Biomass can be converted to sugars by hydrolysis with enzymes or mineral acids. These sugars can be converted into a number of chemical intermediates in biological reactors. Biological reactions are generally slow and selection of the most efficient reactor is important in these applications.

Immobilized cell reactors allow high cell densities and high throughput by attaching microorganisms to a fixed support. This paper compares the rate of production of ethanol from glucose by Saccharomyces Cerevisiae in a packed column and a stirred reactor.

Continuous stirred reactor studies showed a washout rate of .27 hr^-1. The optimum rate of …

Cost Accounting Regulations In Oil And Gas Industries, Lakshmi U. Tatikonda, Rao J. Tatikonda

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

The cost accounting methods that are currently used in the oil and gas Industry are very diverse. Since the 1973 Arab Oil Embargo, increased attention was given to this issue, which resulted in the issuance of SFAS-19 by the FA SB and the SEC’s attempt to develop a new accounting method based on the value of their reserves. The pros and cons of the existing methods are discussed. Also discussed is the need for a uniform accounting procedure.
