The Zeus Copper Uranium Critical Experiment At Ncerc

A critical experiment was performed to provide nuclear data in a non-thermal neutron spectrum and to reestablish experimental capability relevant to Stockpile Stewardship and Technical Nuclear Forensic programs. Irradiation foils were placed at specific locations in the Zeus all oralloy critical experiment to obtain fission ratios. These ratios were compared with others from other critical assemblies to assess the degree of softness in the neutron spectrum. This critical experiment was performed at the National Criticality Experiments Research Center (NCERC) in Nevada.

In 2002, sixty international specialists met to discuss problems of high P-unavailability as a soil nutrient for crops, and the hazards of increased phosphate input to aquatic habitats from industrial and mining activities, sewage disposal, detergents, and other sources. Among the presentations were updated solutions to enhance P-uptake by plants, bioremediation potential in the rehabilitation of ecosystems, taxonomic characterization interactions with mycorrizae, the physiological and molecular basis of PSM, and more.

The nature and origin of the small-scale volcanic systems, generally referred to as 'monogenetic', have enjoyed an elevated level of interest during the past decade. There has been recognition that their ostensibly simple volcano types are a window into the nature of explosive volcanism, landscape evolution and the processes of magma generation in the Earth’s upper mantle. In the past few years, major conferences have offered specialized technical sessions dealing with monogenetic volcanism and there have been thematic conferences, such as the IAVCEI International Maar Conference series, which have provided a focus for discussion of volcanological and geochemical aspects of small-scale basaltic volcanism. Many new aspects of monogenetic volcanism have emerged and have clearly demonstrated that this volcanism can be very complex on a fine scale. This book is a collection of papers arising from two recent Maar Conferences (the fifth in Queretaro Mexico and the sixth in Changchun, China) and serves as a snapshot of current research on monogenetic volcanism.

The aims of this book are: • to contribute to professional development of those directly involved in science education (science teachers, elementary and secondary science teacher advisors, researchers in science education, etc), • to contribute to the improvement of the quality of science education at all levels of education with the exploitation of elements from History of Science incorporated in science teaching –it is argued that through such approaches the students’ motivation can be raised, their romantic understanding can be developed and consequently their conceptual understanding of science concepts can be improved since these approaches make science more attractive to them– and • to contribute to the debate about science education at the international level in order to find new ways for further inquiry on the issues that the book is dealing with. The book is divided in two parts: The first expounds its philosophical and epistemological framework and the second combines theory and praxis, the theoretical insights with their practical applications.

The IGISOL group at the University of Jyväskyla studies the properties of nuclei far off the line of beta stability. These studies are performed locally at the Jyväskylä Ion Guide Isotope Separator On-Line (IGISOL) facility, as well as at a number of other laboratories such as the ISOLDE facility in CERN, at GANIL and in Helmholzzentrum GSI, the location of the future radioactive beam facility FAIR. The group is also actively involved in work to support the development of international future facilities EURISOL and aforementioned FAIR. This book presents carefully selected papers to portrait the work at IGISOL. Previously published in the journals Hyperfine Interactions and European Physical Journal A.

The Sandia Pulsed Reactor Facility (SPRF) is a laboratory facility specifically designed for radiation effects experiments which require an intense pulse of fast neutrons and gamma rays.
