Control Of Trace Elements During The Increasing Development Of Coal For Energy, Bobby G. Wixson, Ernst Bolter

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

The question of an energy crisis continues as many people in the United States have difficulty and become confused with what seems to be a continuing excess of gasoline, oil products and questionable reporting of price increases and profit margin by energy companies. However, the majority of the scientific and engineering community, knowledgable politicians and the general public realize that the energy crisis is real. Fortunately there still remains time to practice conservation and the development of alternative and new sources of energy if the United States can unite and implement a viable energy plan.

Barriers And Incentives To The Commercialization Of Solar Heating And Cooling Of Buildings, Dennis R. Costello, David M. Posner

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

This paper reviews potential barriers to the widespread use of solar heating and cooling systems in residential and commercial buildings.

Heat Pumps Without Supplemental Heat, Carl W. Glaser

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

Through the past few years, fuel used to generate electricity has climbed steadily in cost resulting in a new and much higher level of acceptance for the air to air heat pump system. Manufacturers have improved the product tremendously and have established a level of reliability approaching that of the conventional air conditioner. The fact that heat pumps reduce the cost of heating by 30% to 50% over conventional electric resistance heating and that natural gas is not available in many parts of the country has resulted in more and more heat pumps being installed in homes. While the benefits …

Energy Conservation In Buildings -- The Missouri Plan, Jack Whittier, Bill Jurkiewicz, Weston Fisher

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

In 1974, approximately 23 percent (256.5 trillion Btu's) of Missouri energy was consumed in the residential sector. In 1980, this figure is projected to be 246.6 trillion Btu's (21 percent) (ref. 1). The reduction reflects already implemented conservation activities and the increased use of electric heating at higher end point efficiency. Estimates suggest that energy savings of nearly 50 percent could be achieved in this sector, primarily by upgrading the thermal efficiency of building structures and changing user behavior patterns. This given potential, the reduction of energy consumption in this sector has become a major target of the Missouri Energy …

Attainability And Nonattainability Under Anti-Pollution Laws, J. David Reed, John H. Hoag

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

The central issue with which this paper deals is the effectiveness of alternative air pollution control standards presently in use in the United States. More specifically, an analysis and comparison of effluent air standards versus ambient air standards will be performed. The question of effectiveness will be in the context of how well the alternative pollution control measures achieve society's expectations as goals when the standards are imposed. Society's views are assumed to be reflected through a regional (state) planner. The analysis is performed through the use of optimal control techniques. Initially the effluent air standards model will be examined. …

Dynamic Pullout Resistance Of Anchors Buried In Dry Sand, Chris John Veesaert

Masters Theses

"The vertical pullout resistance of buried anchors subjected to dynamic loading was investigated by means of a laboratory model study. A dry uniformly graded sand, compacted by vibration to 92% of its relative density, was used as the test medium. Tests were performed in a 24-inch square tank using 3.0 and 5.0-inch diameter half and full-anchors. The anchors were tested at depths ranging from 5.0 to 21.0 inches.

It was assumed that the dynamic failure mechanism of earth anchors was the same as the static failure mode, and not distinct behavior. Thus static tests, i.e., tests using a constant strain …

The present design provisions were developed primarily on the basis of the tests conducted by George Winter and his associates at Cornell University. Additional tests were recently made by Popowich 5 on multi-bolt connections and by Dhalla 6 on connections with …

Mechanical Connections In Cold-Formed Steel: Comprehensive Test Procedures And Evaluation Methods, John Fraczek, George Winter, Teoman Peköz

CCFSS Library (1939 - present)

Design equations do not exist for connections in cold-formed steel formed with most types of mechanical fasteners, and such designs are presently based on test results. A lack of standard test procedures and corresponding evaluation methods impedes the acceptance of connection designs and the exchange of information vital to understanding the connection performance of a large number of mechanical fasteners with diverse properties. Initial steps toward standardization are taken with the development of fixtures and procedures for single shear, pullout and pull-over tests. The proposed single shear tests employ both a simple specimen formed with two overlapping straps and a …
