Investigating Microcosms and Macrocosms: The history of the department of Chemistry and Physics 1853-2003 at Arcadia University (formerly Beaver College)

This unpublished manuscript by Professor Emeritus Arthur Breyer covers the history and development of the Department of Chemistry and Physics at Arcadia University (Beaver College) from its beginnings in 1853 until 2003. Topics covered include the role of the physical sciences and the department in the development of the University; departmental accreditation with the American Chemical Society; faculty biographies, awards, and grants; and student awards, senior thesis topics, accomplishments, and outcomes

Petrography and inorganic geochemistry of the Rosebud coal seam at the Absaloka, Big Sky and Rosebud mines, Powder River Basin, Montana

Quantitative maceral and microlithotype analyses, huminite reflectance measurements and inorganic constituent analyses of the samples of the Rosebud subbituminous coal seam from the Absaloka, Big Sky and Rosebud Mines were used in the interpretation of the depositional environment of the seam and for prediction of ash formation during combustion. The mean huminite reflectance varies from 0.31% at the Rosebud Mine to 0.34% at the Absaloka Mine and 0.39% at the Big Sky Mine, indicating that the coal rank is transitional from lignite to subbituminous C. Despite the variation in huminite reflectance, samples from the three mines are similar in mean content of huminite (76 to 81 vol%), liptinite (4 to 6 vol%) and minerals (3 to 4 vol%), but somewhat variable in inertinite (10 to 16 vol%). A direct correlation of mean huminite reflectance with mean huminite abundance and an inverse correlation with mean inertinite abundance suggests a possible correlation . between coalification and floral precursors. Within-seam variations in petrographic composition and huminite reflectance are high. Lithologic layering with similar sequence and thickness in the Absaloka and Big Sky profiles is delineated by petrographic variation, suggesting similar geological histories for the two sites. A depositional environment transitional between reed marsh and forest swamp in a fluvial-deltaic system, is suggested for the Rosebud seam based on interpretation of microlithotype and maceral compositions. Clay minerals, quartz and calcite are the most abundant mineral phases in the Rosebud seam. Except for the top 0.3 m, the seam:,it the Big Sky Mine has mean pyrite content as low as 0.4 wt%. A phosphate mineral, crandallite(?), occurs as an abundant authigenic mineral in some layers. Crandallite and associated kaolinite, quartz, zircon, rutile and apatite, may have originated from volcanic ash. Maceral-associated inorganic elements have significant abundance in ulminite, fusinite and detrogelinite. The most abundant element is Ca, followed by Al, S, Mg, Si, Cl and Na. These elements in macerals aie interpreted either as ions associated with carboxylate groups or as coordination complexes in the maceral molecular structure and are a major contributor to low-temperature fouling deposits in utility boilers firing the Rosebud coal

Economics of Residential Heat Recovery Units

Determining residential airconditioning waste heat recovery system costs and savings is achieved using a computer program. A worksheet is designed to accept consumer data as an input to the program. The program features load and waste heat recovery calculations on a monthly basis. Economic criteria, including rate of return, present worth, and payback period are computed. Sensitivity of these criteria to fuel escalation and consumer discount rate is demonstrated. the program provides the user with both thermal analysis and economic analysis summary reports

Ergonomic Models of Anthropometry, Human Biomechanics and Operator-Equipment Interfaces

The Committee on Human Factors was established in October 1980 by the Commission on Behavioral and Social Sciences and Education of the National Research Council. The committee is sponsored by the Office of Naval Research, the Air Force Office of Scientific Research, the Army Research Institute for the Behavioral and Social Sciences, the National Aeronautics and Space Administration, and the National Science Foundation. The workshop discussed the following: anthropometric models; biomechanical models; human-machine interface models; and research recommendations. A 17-page bibliography is included
