Oil Spill Containment And Removal In Arctic Ecosystems, Wilfred R. Mcleod, Diana L. Mcleod
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Statistics on 16 arctic and subarctic oil spills, their locations, the amount of oil spilled, combatant schemes used, and causes for the spills were culled from the literature. This information has been used to analyze the effectiveness of available chemical, mechanical, and destructive means of oil recovery or disposal under arctic and subarctic conditions.
The choice of the best cleanup procedures to follow in any particular instance is clouded by a number of variables and must be weighed against such considerations as wind, sea, and ice conditions, properties of the oil, and effects of chemicals on marine and wildlife. Access …

Solar-Thermal Energy Conversion, E. R. G. Eckert
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The fact that our conventional fuel resources are finite and will be exhausted some time in the future gives impetus to a consideration of solar radiation for conversion into heat or electric power. The characteristics of the solar radiation - that the enrgy flux density is small and that it arrives intermittently on the ground of our glove has to be considered in any system utilizing this energy source. For home heating parts of the roof offer a sufficiently large area, for electric power production areas of some km2 are required to collect a sufficient amount of energy. Optical …

Let me share with you a quotation from a report issued bv the Chase Manhattan Bank while the Arab oil embargo was still in effect. "Reportedly, the annual cost of a gasoline rationing program would amount to $1.4 billion. Based upon past results, if that much money was devoted to an exploratory effort, it would be potentially capable of discovering more than 2 billion barrels of petroleum. That amount of petroleum would be equal to 19 percent more than all the gasoline consumed in privately owned automobiles in 1973."
While the threat of rationing has disappeared with an end to …

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Growth and reproduction may be stimulated by increased temperature in the cooling system and thermal plume during seasons when ambient water temperature is less than optimum, but growth, reproduction and survival are reduced when the elevated temperatures become excessive. Some fish species congregate in the warm thermal plumes during cold seasons but are excluded from this living space by temperatures above their preference in the summer. However, the warm refuge provided by a thermal plume in cold seasons can be a death trap if a power plant shuts down suddenly and exposes the fish to cold shock exceeding their lower …

Monsanto's Energy Conservation Program, Ray E. Doerr
Monsanto's Energy Conservation Program, Ray E. Doerr
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy conservation is not new to Monsanto. We have had utility and process improvement programs for many years. But the motivation of these programs was to reduce our operating costs and improve profits. However, these programs did result in substantial energy savings.
Now, however, Monsanto is placing major emphasis on a broad-scale energy conservation program for all Monsanto locations. The energy saving potential is great and is necessary because of the energy shortage as well as the rapidly escalating energy costs.

My presentation will cover the basic procedure used by the Emerson Electric Co. to conserve energy in Its operations. And because people frequently tell me how much they like or dislike our television sets, and how concerned they are or are not about the depth of our involvement in furnishing material for the Defense Department, at this point I would like to give a short commercial. Hopefully, it will dispel misconceptions, and define the use of energy in Emerson's operations.

Development Of Industrial Energy Management Programs, Michael C. Noland
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy management is a term which has only recently been entered in the business management lexicon. Until recently business managers, even the most successful ones, devoted only casual thought to the need to manage their use of fuels and electricity. Energy was cheap and plentiful. Economic sense dictated that if labor could be replaced by more energy-intense processes or equipment, the smart manager did so. Local and national policy, industrial process design, consumer habits--all these and more encouraged massive energy consumption.

A Solar-Hydrogen Energy Conversion Scheme For Agricultural Use, R. L. Reisbig, Jack L. Boone, Gordon E. Weiss, Thomas Van Doren
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
A solar energy activated system is presented which can produce hydrogen and hydrogen-derived fuels (methanol) for use on farms. The device, named "solar-kine", also can produce fertilizer (anhydrous ammonia) as a byproduct of the hydrogen. A cost analysis shows that solar-kine may be mass-producible and sold to farmers for between $7,200 and $14,700. This is equivalent to giving the fanner energy at a price of $1.79 to $3.66 per million BTU's (in 1974 dollars). Presently (Spring, 1974) regular gasoline used in tractors at 43¢ per gallon, represents a cost to the farmer of $3.77 per million BTU's. As oil-based fuels …

Auditing Program For Effective Energy Conservation, S. Noble Robinson
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Mallinckrodt Chemical Works has developed and is using a special audit format to identify conservation opportunities for all its utilities. Manufacturing, Utilities, R & D, and Engineering personnel are collected together for several days during which time a process or operation is subjected to an intense analyses of its utilities consumption, a brain-storming of conservation ideas, and then an "on-the-spot" engineering analysis of the economics and feasibility of each idea. This technique is a fast, comprehensive way to assess conservation potentials while committing the attention of those operating groups that can implement the ideas.

Pb And Bi L-Subshell Ionization Cross-Section Ratios Versus Proton Bombarding Energy From 0.5 To 4 Mev, Don H. Madison, A. B. Baskin, C. E. Busch, Stephen M. Shafroth
Physics Faculty Research & Creative Works
Experimental ratios of L-subshell cross sections are given for ionization of lead and bismuth by 0.5-4-MeV-proton bombardment. The ratio of the LII to LI cross sections exhibits a maximum near 1.75 MeV. Individual subshell cross sections are obtained from the experimental ratios and previous total-cross-section data. These subshell ratios and cross sections are compared with the theoretical predictions of the plane-wave Born approximation using nonrelativistic hydrogenic wave functions, of the binary-encounter approximation scaled from Mg K-shell cross sections, and of the binary-encounter approximation scaled from cross sections obtained using L-shell velocity distributions. It was found that both approximations …
Diffusion-Controlled Intrachain Reactions Of Polymers. I Theory, Gerald Wilemski, Marshall Fixman
Diffusion-Controlled Intrachain Reactions Of Polymers. I Theory, Gerald Wilemski, Marshall Fixman
Physics Faculty Research & Creative Works
A theory of diffusion-controlled intramolecularly catalyzed reactions of polymer chains in dilute solution is formulated. A closure approximation yields a soluble integral equation for (essentially) the transient rate of the reaction. The time dependent solution consists of a sum of simple exponential terms whose coefficients and decay constants can be readily calculated. The theory is also applied to luminescence quenching and ring-chain interconversion.

Diffusion-Controlled Intrachain Reactions Of Polymers. Ii Results For A Pair Of Terminal Reactive Groups, Gerald Wilemski, Marshall Fixman
Physics Faculty Research & Creative Works
The formulas and results of the preceding paper are used to calculate the rate of reaction between reactive groups attached to the ends of a polymer chain. Extensive numerical calculations have been made for both transient rate processes and steady state luminescence quenching. The results are restricted to chains in dilute solution, in either the free draining or nondraining limits and with no excluded volume forces present. A discussion of the qualitative effects of excluded volume forces on the results is included. The results suggest that experimental studies of these processes may be feasible.
Eikonal Approximation Applied To Atom-Atom Excitation At Intermediate Energies: Excitation Of H By H, Richard H. Shields, Jerry Peacher
Eikonal Approximation Applied To Atom-Atom Excitation At Intermediate Energies: Excitation Of H By H, Richard H. Shields, Jerry Peacher
Physics Faculty Research & Creative Works
The eikonal distorted-wave Born approximation (DWBA) developed recently by Chen, Joachain, and Watson is applied to atom-atom excitation in the intermediate energy range. In this paper the excitation of a hydrogen atom to the 2s, 2p±, or 2p0 state by hydrogen impact is considered. Differential cross sections are presented. Total cross sections are presented and compared to previous calculations. It is shown that the eikonal DWBA results for the total cross section approach the two-state distortion-approximation results in the limit of high energy and very-small-angle scattering.

Oxidation Reactions Of Unsaturated Hydrocarbons For Fuel Cells, James W. Johnson, William Joseph James, A. K. Agrawal
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The anodic oxidation of unsaturated hydrocarbons has been the subject of numerous studies, primarily on Pt and Au electrodes at low temperatures, < 100°C. The complete oxidation to CO2 is usually the predominant reaction with both H2O and OH- having been proposed as the oxygen source. Usually a single study consists of a comprehensive investigation of a single compound on a single electrode or a somewhat limited study of several compounds on a single electrode. A diversity of proposed mechanisms has resulted and is illustrated by the following summary.

History Of So2 Removal System At The Meramec Plant Of Union Electric, Gerald E. Dreifke, John F. Mclaughlin, Jerrel D. Smith
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
In line with the then emerging air pollution control regulations Union Electric installed a limestone injection wet scrubber sulfur dioxide removal system on an intermediate size coal-fired utility boiler at its Meramec Power Plant on an experimental basis in September, 1968. During approximately 3 years of operation many difficulties were encountered with plugging and scaling of various system components by calcium sulphate. As a result of this experience along with related experiences by other utilities employing similar systems, the experiment was terminated in June, 1971.
As a result of the experiences gained, however, second generation experiments in sulfur dioxide removal …
