A CO2-Silica Geothermometer for Low Temperature Geothermal Resource Assessment, with Application to Resources in the Safford Basin, Arizona
No full textData collected for this study include ground water chemical analysis, drillers" logs of water wells, geohydrologic and geologic information. Published chemical analysis were compiled from Witcher, 1981; Swanberg and others, 1977; Muller and others, 1973; Dutt and McCreary, 1970; and Hem, 1950. Additional analysis from an area near Buena Vista were obtained from a University of Arizona Master's thesis on a sub-economic mineral deposit (Yarter, 1981). Knechtel (1938) published several analysis from the area in a U.S. Geological Survey Water Supply Paper. Knechtel"s data were not included in our data base because they were relatively incomplete. Unpublished chemical analyses were obtained from files of the city of Safford"s engineers" office and from files of the U. S. Geological Survey, Water Resources Division, Tucson. Because available published and unpublished chemical analysis usually had no aluminum, boron, or lithium analysis and because reliability of pH and alkalinity data were generally unknown, field collection of an additional 42 chemical analysis of ground water was performed. Drillers' logs and geohydrologic information were obtained from Knechtel, 1938; Witcher, 1982; and from files of the Arizona Department of Water Resources, Phoenix and the U. S. Geological Survey, Water Resources Division, Tucson.Documents in the AZGS Document Repository collection are made available by the Arizona Geological Survey (AZGS) and the University Libraries at the University of Arizona.

Product Innovation Knowledge Transfer for Developing Countries: Towards a systematic Transfer Approach
No full textThe transfer of knowledge on product innovation to small- and medium-sized enterprises and local knowledge institutions in developing countries is expected to be one of the key drivers for competiveness and economical growth, and a part of the solution to environmental and social challenge. In that respect, this PhD study focuses on how the process of the current knowledge transfer takes place and how it can be improved. A combination of literature review and empirical research has resulted into a conceptual framework to describe the complex and dynamic process of product innovation knowledge transfer to developing countries. In order to improve this process, a systematic approach has been developed and operationalized by a needs assessment tool and a design manual: The UNEP Design for Sustainability for Developing Economies (D4S-DE) Manual (www.d4s-de.org). Both tools have been tested in practice by practitioners and have been evaluated by an academic review board.Design EngineeringIndustrial Design Engineerin
Where do we draw lines: professional relationship boundaries and the child and youth care practitioner
No full textThe question of professional relationship boundaries is a poignant one, in light of the many boundary grey-zones that are created by the variety of young people’s needs, practice settings and professional relationship contexts within the field of child and youth care. In order to support practitioners’ development of critical thought and awareness of professional boundaries, this paper applies a professional relationship boundaries conceptual framework to child and youth care work, and the literature is consulted to explore the impacts of boundary violations, influences on individual’s boundaries, cues to indicate blurring boundaries, and key strategies to maintain balanced boundaries

J.C. Painter letter to Benjamin Lundy
No full textLetter from J.E. Painter to (presumably) Benjamin Lundy, answering a request for information about the history and operations of the Underground Railroad. Letter includes details of a story of an ex-slave transported on the Underground Railroad through Ohio and stories of the plight of other fugitive slaves crossing the Ohio River.
Benjamin Lundy (1789-1839) was a prominent Quaker abolitionist best known for his development of abolitionist periodicals. His "Genius of Universal Emancipation" was first published in 1821 from his home in Mt. Pleasant, Ohio, and enjoyed a wide circulation across the antebellum United States. In the 1820s, the young William Lloyd Garrison came to work for The Genius. Benjamin Lundy traveled widely seeking subscriptions to The Genius, giving talks about the anti-slavery movement, and observing and documenting the conditions of enslaved people across the Americas. He was also involved in the establishment of freed slave colonies in Mexico

Carbon Sequestration Potential at the 1 Alpine-Federal Site in East-Central Arizona
No full textThis open-file report describes the carbon-sequestration potential at the site of the 1 Alpine-Federal geothermal test drill hole, which is located south of Springerville in central eastern Arizona near the New Mexico border. A previous report, Arizona Geological Survey (AZGS) Open-File Report OFR 94-1, version 2.0, describes the subsurface geology encountered in the 1 Alpine-Federal well in much more detail than this new report. The 1 Alpine-Federal geothermal test, at an elevation of 8,556 ft in eastern Arizona, was drilled by the Arizona Department of Commerce and U.S. Department of Energy to obtain information about the hot-dry-rock potential of Precambrian rocks in the Alpine-Nutrioso area, a region of extensive Quaternary basaltic volcanism in southern Apache County. The hole reached total depth of 4,505 ft (1373 m) in August 1993. Temperature measurements were taken through October 1993 when final temperature, gamma ray, and neutron logs were run. Details on the temperature gradients, geothermal potential, and geology encountered in the 1 Alpine-Federal are presented in AZGS Contributed Reports CR-94-D, CR-94-E, and CR-94-F (Witcher, J.C., 1994; Witcher, J.C., et. al. 1994; and Witcher, J.C., Hahman, W.R., and Swanberg, C.A., 1994a), and in New Mexico Geological Society Guidebook, 45th Field Conference (Witcher, J.C., Hahman, W.R., and Swanberg, C.A., 1994b).

Turbulent wakes of plates with non-equilibrium similarity scalings
No full textWe have conducted hot wire anemometry measurements of six different axisymmetric turbulent wakes which demonstrate the existence in all these wakes of non-equilibrium mean flow profile scalings and of the underlying self-preservation and non-equilibrium dissipation scalings. These mean flow profile scalings are different from those of all documented canonical boundary-free turbulent shear flows to date, all of which have been established for very far downstream regions
Energy dissipation and flux laws for unsteady turbulence
No full textDirect Numerical Simulations of spatially periodic unsteady turbulence show that the high Reynolds number scalings of the instantaneous energy dissipation rate and interscale energy flux at intermediate wavenumbers are qualitatively different from the well-known cornerstone scalings of equilibrium turbulence where and are time-dependent rms velocity and integral length-scales. Instead, they both scale as where and are length and velocity scales characterizing initial/overall unsteady turbulence conditions
