Rate Of Return Regulatory Policy -- The Bane Of Electric Utilities?, Charles David Laderoute

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

In the past,rate of return regulation served to the advantage of electric utility stockholders. Today this is no longer the case. Furthermore, owners cannot assume that utility management can or will work totally in their behalf. As a result, this paper presents as its main thesis that utility stockholders should band together into advocacy groups to support their right to a fair rate of return.

Surface Heating Greenhouses With Waste Heat, P. N. Walker, H. J. Rand

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

Surface heating of greenhouses is done by applying waste heated water on the outside of the greenhouse at the ridge and allowing this water to flow in a thin layer over the roof and sidewall surfaces. The water is then collected in gutters and returned to its source. The main advantages of this heating system over others for heating greenhouses with waste heat are its low capital costs and the fact that it can utilize wastes at quite low temperatures. This system can make effective use of water at temperatures as low or perhaps lower than the temperature to be …

Umr Minerals Building: An Innovative Approach To The Construction Of Underground Buildings, Bruce H. Green, David A. Summers

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

The original intent of the exercice was to develop a design for a new minerals engineering building which would demonstrate the applicability and feasibility of an underground building complex to our administration and to the Board of Curators. Two major advantages were foreseen for such a building. Not only would it be immensely superior, in terms of energy demand, to the conventional aboveground buildings previously constructed by the University, but it also would have highly significant symbollic and educational effects on the students of the several disciplines comprising the UMR "School of Mines and Metallurgy". It would also serve as …

Superconducting Magnetic Energy Storage: A Cost And Sizing Study, Haur D. Shaw, J. Derald Morgan, Max Darwin Anderson

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

Two applications for superconducting magnetic energy storage (SMES) devices in power systems are studied. One is for peak shaving, and the other is for load leveling. Consideration is given to placing these devices near load centers to reduce the line losses. For (SMES) cases studied using smaller size devices at several load centers, the line losses are lowered. However, the efficiency of SMES is proportional to its size, and the capitol cost per MWH is much greater for a smaller size SMES unit when compared to a larger SMES unit. Once the location or locations for SMES have been selected, …

Economics, Politics And The Future Supply Of Energy Sources, Raphael Shen

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

High degree forward linkages created by oil and natural gas consumption was sufficient "justification" to regulate energy prices. The "welfare triangle" was artificially enlarged, and the economy as a whole indeed reaped benefits therefrom. It was workable, then. But the economy has since been experiencing macroeconomic dislocations. To avoid future payments of current policy mistakes, to ensure continued and steady economic growth, and to assure future energy adequacy/ abundance, enhanced investment incentives are rational imperatives that merit serious consideration.

An Analysis Of Residential Water Demand Schedules In Arkansas, Richard K. Ford, Joseph A. Zieger

Arkansas Water Resources Center Technical Reports

Water has held man's interest for centuries, and a considerable body of knowledqe has been developed about this subject, but it has only been considered only recently by decision makers in an economic sense. Because water is required to sustain life, the thought of its being an economic good to individuals has not been considered applicable or "fair" by those individuals who are concerned with its acquisition and distribution. Moreover, water has been in fairly abundant supply relative to demand for most of the country. However, as this situation is upset by increases in population and water use, a realization …

Distribution Of Trace Elements In A Warm Water Release Impoundment, J. Nix

Arkansas Water Resources Center Technical Reports

A detailed water quality survey (including trace metals) was conducted on DeGray Reservoir in south west Arkansas from 1969 through 1975. The results of this investigation are used to describe physical and chemical processes which affect the concentration of many of the constituents found in the reservoir and river system. Detailed dissolved oxygen profiles as well as turbidity (% transmittance) profiles were useful in delineating the movement of water through the reservoir. Underflows, innerflows, and overflows were observed during different seasons. The development of a metalimnetic dissolved oxygen minima appears to be related to advective transport within the metalimnion. Metalimnetic …

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 …

Nebraska, Iowa, Kansas, and Missouri, which make up EPA Region VII, are among the leading corn and wheat producing States in the Nation_ These States also produce a significant share of the soybean, grain sorghum, fat cattle, and finished hogs that are supplied to American and foreign markets.

Although the States in Region VII can best be characterized as rural, 65 percent of their nearly 12 million people live in urban areas. In Nebraska, metropolitan areas such as Omaha 4 have environmental problems resulting from major industrial operations, municipal services, transportation, and energy production. Metropolitan areas, however, do not have …

Effect Of Fish Size On Prey Size Selection In Gambusia Affinis, Wayne A. Wurtsbaugh, Joseph J. Cech Jr., James Compton

Watershed Sciences Faculty Publications

Food size selection of the mosquitofish , Gambusia affinis affinis. was measured in aquaria using juvenile stages of the mosquito, Clllex tarsalb;, as prey. Fish size varied from recently born fry to large adult females. Food size selection was positively correlated with fish size. Mosquitofish fry (6-8 111m standard length) attacked and ate primarily first and second instar larvae. Fry attacked larger instars, but attack success on these was low (0 - 50%). Fish larger than 20 mm attached primarily pupae and third and fourth instar larva. No first instar mosquitoes were eaten. Attack success for these fish was above …

Mass Marking Of Mosquitofish: Preliminary Results, Bruce Vondracek, Wayne A. Wurtsbaugh, Joseph J. Cech Jr.

Watershed Sciences Faculty Publications

Three marking techniques were tested to determine their applicability for mosquitofish. Tetracycline drugs and DC Ar administered in the diet successfully marked laboratory-cultured mosquitofish, but exposure to direct sunlight in outdoor tanks resulted in the rapid disappearance of the marks. Preliminary data on fluorescent marks from a polystyrene pigment in a melamine-sulfonamide-formaldehyde resin forced into the dermal ,tissue with compressed air are more promising.

A t an optimal deliver pressure of 7.3 m Hg (140 p.s.i.) and spraying time of 15 sec., marking percentage is maximized and fish mortality is minimized. Mark retention time was up to 80 days in …

A Five Year Water Research Plan For The State Of Arkansas, Robert E. Babcock

Arkansas Water Resources Center Technical Reports

The present economy and quality of life in Arkansas have largely been determined by our natural resources and the way they have been used. Likewise, insuring a sound economic future and a healthful environment in the state will depend on the efficiency and the wisdom with which nature's gifts are managed in the future. As the state's population grows and places new demands on finite resources, the need for effective resource management becomes increasingly critical. Often, a history of plenty can lead to the belated recognition of emerging resource problems. In Arkansas, such is the case with the state's water …
