07261 Abstracts Collection -- Fair Division

From 24.06. to 29.06.2007, the Dagstuhl Seminar 07261 % generate automatically ``Fair Division\u27\u27 % generate automatically was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available

A Calorimetric Investigation of Zirconium, Titanium, and Zirconium Alloys from 60 to 960°C

Structural materials for nuclear reactors must meet three stringent conditions: they must have adequate mechanical properties at the operating temperature, they must be corrosion resistant to the heat transfer medium (air, water, or alkali metals), and they must not absorb neutrons excessively. This last requirement is a particularly stringent one, for it is met by only four accessible metals: aluminum, magnesium, beryllium, and zirconium, as Table I shows. For reactors which operate at low temperatures, aluminum serves as an excellent constructional material, but it cannot be used for more efficient high-temperature reactors, because of its low elevated temperature strength associated with its low melting point of 660 °C. Although magnesium has a lower absorption cross section than aluminum, it has a lower melting point (650 °C) and poorer corrosion resistance, thus offering no particular advantages over aluminum. The use of beryllium is impractical except for very special applications, because of its extreme brittleness and the relative scarcity of its ores. In contrast, zirconium ores are abundant; the metal is fairly easily produced; it has satisfactory mechanical properties and excellent corrosion resistance at temperatures above the practical operating range for aluminum; and techniques of fabrication are now well developed. Thus zirconium comes at once to the foreground as a structural material for the construction of nuclear reactors

Cloud Radiation Forcings and Feedbacks: General Circulation Model Tests and Observational Validation

Using an atmospheric general circulation model (the National Center for Atmospheric Research Community Climate Model: CCM2), the effects on climate sensitivity of several different cloud radiation parameterizations have been investigated. In addition to the original cloud radiation scheme of CCM2, four parameterizations incorporating prognostic cloud water were tested: one version with prescribed cloud radiative properties and three other versions with interactive cloud radiative properties. The authors' numerical experiments employ perpetual July integrations driven by globally constant sea surface temperature forcings of two degrees, both positive and negative. A diagnostic radiation calculation has been applied to investigate the partial contributions of high, middle, and low cloud to the total cloud radiative forcing, as well as the contributions of water vapor, temperature, and cloud to the net climate feedback. The high cloud net radiative forcing is positive, and the middle and low cloud net radiative forcings are negative. The total net cloud forcing is negative in all of the model versions. The effect of interactive cloud radiative properties on global climate sensitivity is significant. The net cloud radiative feedbacks consist of quite different shortwave and longwave components between the schemes with interactive cloud radiative properties and the schemes with specified properties. The increase in cloud water content in the warmer climate leads to optically thicker middle- and low-level clouds and in turn to negative shortwave feedbacks for the interactive radiative schemes, while the decrease in cloud amount simply produces a positive shortwave feedback for the schemes with a specified cloud water path. For the longwave feedbacks, the decrease in high effective cloudiness for the schemes without interactive radiative properties leads to a negative feedback, while for the other cases, the longwave feedback is positive. These cloud radiation parameterizations are empirically validated by using a single-column diagnostic model. together with measurements from the Atmospheric Radiation Measurement program and from the Tropical Ocean Global Atmosphere Combined Ocean-Atmosphere Response Experiment. The inclusion of prognostic cloud water produces a notable improvement in the realism of the parameterizations, as judged by these observations. Furthermore, the observational evidence suggests that deriving cloud radiative properties from cloud water content and microphysical characteristics is a promising route to further improvement
