Download or read book Strategic Science in the Public Interest written by G. Bruce Doern and published by University of Toronto Press. This book was released on 2007-01-01 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past twenty years have seen considerable shifts and struggles in government science that is, in the way the state funds, supports, regulates, conducts and uses scientific and technological activity. Focusing on federal labs and agencies, Strategic Science in the Public Interest explores how these labs have been located within, and often buried by, the larger commercially-focussed federal innovation agenda. G. Bruce Doern and Jeffrey S. Kinder examine four labs whose mandates deal with the Alberta oil sands, environmental technologies, wildlife research, and mining and metals, respectively. The authors use these cases to explain why a better middle-level approach to analysis is needed for strategic public interest-centred government science. They illustrate the importance of understanding the variety, as well as the similarity, of federal science and technology labs and agencies, and of instituting policies that reflect this diversity. The growing importance of Related Science Activities (RSA) is also explored, as well as the core trade-offs between commercial and public goods science in their mandates and their internal capacities.

This book was released on 2006-01-16 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: This broad review is the first to gather comprehensive information on the complete contemporary range of toxicity testing procedures and hazard assessment procedures, which is normally scattered and difficult to find. The two-volume set provides a consistent, template-based approach, linking relevant information on background, theory and practice to each bioassay. Volume 2 examines hazard assessment schemes. Includes extensive glossary.

Book excerpt: Zircaloy-4 fuel sheath specimens 15.2 mm diameter by 0.42 mm wall thickness with beryllium-brazed appendages have been laboratory tested at high temperature with internal gas pressurization and inert gas shielding of the outer surfaces. with sufficient hoop stress at temperatures less than 1073 k cracks, which were due to a beryllium assisted crack penetration mechanism, were found to occur at the appendages. formulae to predict the beryllium penetration and rupture have been derived by westinghouse canada ltd. based on data from direct resistance-heated specimens. the formulae are thought to be able to predict the phenomenon in fuel sheaths with changing temperature/pressure histories. a series of tests was done by canadian general electric to determine the formulae ability to predict the occurrence of beryllium assisted crack penetration in specimens heated indirectly with internal heaters. the tests showed: 1) there is an incubation period before any beryllium assisted crack penetration occurs. 2) at sheath temperatures below approximately equal to 1073 k sheath rupture by excessive mechanical strain will preclude rupture by beryllium assisted crack penetration. 3) the formulae predicted rupture times above and below the braze alloy melting temperature within the previously determined confidence limits. 4) predictions of beryllium assisted crack penetration rupture for specimens with changing temperature/pressure histories were of similar accuracy to predictions of isothermal tests. 5) specimens with an appendage plane of one bearing pad and three spacer pads behaved similarly to the specimens with four spacer pads on which the formulae were based.

Download or read book Automation in Mining Mineral and Metal Processing written by J. O'Shea and published by Elsevier. This book was released on 2014-05-20 with total page 679 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automation in Mining, Mineral and Metal Processing covers the proceedings of the Third International Federation of Automatic Control (IFAC) symposium. The book discusses techniques and methods of automatic control and of system analysis for use in mining, mineral, and metal processing industries. Comprised of 69 chapters, the text presents theories, applications, operations, and maintenance of automation systems in an industrial environment. The topics covered are also relevant in solving various issues in the mining, mineral, and metal processing industries, such as pollution, safety, energy efficiency, human resource, and materials through the implementation of an unmanned system. This book will be of great interest to professionals especially those who are contemplating the use of automated system.

Book excerpt: Stress corrosion cracking can potentially cause fuel failures at circumferential ridges in the sheath. finite element computer codes elestres and feast are used to calculate two-dimensional, axisymmetric, elastic-plastic sheath stresses at and near the circumferential ridges. the level of stresses is given by the fuel design (such as pellet/sheath diameters, pellet length, pellet density) and by the operating conditions (such as power history). the accuracy, convergence, and cost of the stress calculations, however, are determined by the discretization used in the calculations: the number of nodes in the finite element mesh; the shape of the individual finite elements; the pattern into which the finite elements are arranged; and the size of the calculation-steps into which the power history is subdivided. in this study, we determined the discretization that gives a reasonable compromise of accuracy, convergence, and cost for the stress calculations. the highest accuracy is obtained by using triangular finite elements of aspect ratios close to one, and assembling them into hexagonal patterns. to caputure the stress gradients, five nodes are required across the sheath wall at the ridge, but two nodes are sufficient near the midplane of the pellet. the resulting mesh contains about 200 nodes and about 300 finite elements. calculation-steps of 6 kw/m provide a convergent solution, with a factor of two margin against numerical divergence. with the above arrangement, feast needs about 2.4 seconds on a cdc/cyber 175 computer to calculate sheath stresses per calculation-step. six radial nodes at the ridge would double the computing cost. decreasing the size of the calculation-steps means more calculations are needed to analyze a given power history, giving a linear increase in computing cost.
