The Essence Of Reality, Michael Geglia
The Development And Validation Of An Assessment Instrument To Measure Environmental Education Competencies For Level Iii Of The Elementary Teacher Training Program At Utah State University, Francine Fukui
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The purpose of this study was to construct and validate an assessment instrument which could effectively measure the impact of implementing an environmental education component to the Level III program of the elementary teacher training program at Utah State University. It was the hope of this researcher that the test would also be administered to Level III students upon completion in subsequent quarters to indicate individual competence in environmental education.
Care was taken in the construction of the instrument to assure content validity of concepts considered important by local, university, and state environmental education reviewers. A preliminary form of the …
Critical Exposure Pathways: An Analysis Of The Environmental Impact Of Gaseous Effluents From Light-Water-Cooled Reactors, Robert Danna
Critical Exposure Pathways: An Analysis Of The Environmental Impact Of Gaseous Effluents From Light-Water-Cooled Reactors, Robert Danna
Retrospective Theses and Dissertations
The analysis of the environmental impact of routine radioactive gaseous releases from operating nuclear power stations is discussed using a radiation dose assessment. This analysis includes a discussion of the origin of radionuclide effluents, a discussion of federal policies, and a calculation of radiation doses to man. A model of estimating the radioactive dose from gaseous effluents from light-water-cooled reactors is described using guidelines described in the Code of Federal Regulations and the Nuclear Regulatory Commission's Regulatory Guides. The environmental impact of these sources is then analyzed using dose rates calculated along critical exposure pathways for various radioactive nuclides. Examples …
Environmental Aspects Of The Nuclear Fuel Cycle And High-Level Radioactive Waste Disposal, Robert S. Kent
Environmental Aspects Of The Nuclear Fuel Cycle And High-Level Radioactive Waste Disposal, Robert S. Kent
Retrospective Theses and Dissertations
An assessment of the environmental effects of the nuclear fuel cycle industries is discussed, reactor waste inventory and standards are presented, and the alternatives for high-level radioactive waste disposal reviewed, with particular attention being given to disposal in deep geological formations on land. One of the major concerns regarding potential impacts of the nuclear fuel cycle industries is the lack of a definite and proven method of disposal of the high-level radioactive wastes from light water moderated reactors. The problem is expected to become more pressing as the nuclear power industry and the associated radioactive waste inventories grow in the …
Molecular Size Distributions Of Heavy Metals In Lake Washington, William B. Andrews
Molecular Size Distributions Of Heavy Metals In Lake Washington, William B. Andrews
Retrospective Theses and Dissertations
Four untreated and one magnesium treated water samples from Lake Washington, the potable water source for the city of Melbourne, Florida, were collected and analyzed for As, Cd, Cr, Cu, Fe, Pb, Ni, Zn, Mb, Ca, and color on the basis of molecular weight distribution. Molecular weight distributions of the samples were obtained using a Millipore ultrafiltration system and filters in the following sizes: 106, 105, 2.5 x 104, 104, and 103 nominal molecular weight limits (nmwl). Color causing materials in the untreated samples were found to be located in the molecular weight fraction greater than 2.5 x 104 nmwl. …
The Biodegredation Of Vehicular Waste Petroleum In The Roadside Environment, Jesse W. Johnson
The Biodegredation Of Vehicular Waste Petroleum In The Roadside Environment, Jesse W. Johnson
Retrospective Theses and Dissertations
Bacteria from dry and wet roadside environments were examined for the ability to degrade hydrocarbons. The kinds and numbers of bacteria observed were similar to those reported in other petroleum contaminated environments. Surface soils (top 2.5 cm) immediately adjacent to the highway pavement and the sediments of shallow drainage ditches contained the highest concentrations of petroleum degrading bacteria (9.8 x 107 CFU/g). Concentration and species diversity of petroleum degrading bacteria decreased with distance from the highway pavement. Chromatographic analysis of highway stormwater runoff and the soil in close proximity to the highway indicated the presence of complex hydrocarbon mixtures of …
Energy Education Materials For Elementary School, Marcia Keizer Fraser
Energy Education Materials For Elementary School, Marcia Keizer Fraser
All Master's Theses
The materials created introduce intermediate elementary level children to a selected basic energy vocabulary and to concepts of energy-environment inter-relations. The approach is multi-dimensional, employing a slide tape presentation, posters, charts, and vocabulary cards. Energy concepts and vocabulary are repeated through the various media forms as a means to reinforce learning. The content tone is deliberately positive so that in the process of gaining knowledge about energy issues, children will feel successful, encouraging further achievement in the area of energy education.
