Global warming reveals that world energy consumption is on an unsustainable path. This updated second edition of The New Energy Crisis examines the impact of climate change on energy economics and geopolitics, exploring key issues such as energy poverty, renewable and nuclear energy, and focusing on the implications of the Fukushima crisis.

Metadata only record ; Though poorly developed from a methodological standpoint, stakeholder analysis (SA) now belongs to the long list of virtues and catchwords reigning over the field of development. Much to its credit, the method travels well across disciplinary and theoretical boundaries. It is so eclectic as to stretch across the political spectrum and fit in with most of what it encounters, be it informed by participatory methodology or not (Burgoyne 1994: 205, Grimble and Wellard 1997: 182). SA is currently used in fields ranging from political science to policy development and international relations. The concept and related methodology have made significant inroads into poverty reduction studies and applied research pertaining to issues of sustainable livelihood, community-based natural resource and conflict management (Ramrez 1999). It is also part of World Bank thinking on participation methodology since about 1993 (MacArthur 1997a: 5). ; Available in SANREM office, FS
Metadata only record ; Research on community-based natural resource management (CBNRM) has paid little attention to key assumptions it uses in the analysis of conflict and conflict management. The concepts of pacifism, egalitarianism, communalism, secularism, and rationalism are built into the community-based approach to natural resource management and are often treated as universal principles. In this paper, we examine differences in cultural perspectives on these assumptions. We also invite researchers to ground their practice of conflict management in the different social and cultural settings they encounter. Through the use of a conversational style of presentation and reference to cases presented in this volume, we attempt to bring the reader closer to oral forms of community-based politics, learning, and teaching, as an alternative approach to resolving differences in perspectives on the meaning of conflict and conflict management.
Composites of 8 mol.% yttria-stabilized zirconia (8YSZ) with graphene nanoplatelets (GNP) have been pointed as alternative interconnectors in SOFC due to their mixed ionic-electronic conduction. Here we show that GNP addition provides rising crack-resistance behavior, with long crack toughness up to 78% higher than that of 8YSZ, also improving its thermal conductivity (up to 6 times for the in-plane direction). Toughness versus crack length is measured for 7 and 11 vol.% of GNP using single edge V-notched beam technique and ultrashort pulsed laser notching; and thermal behavior is analyzed by the laser flash method. Materials also have highly anisotropic coefficient of thermal expansion. These properties contribute to enhance their performance under the harsh operating conditions of SOFC, as thermal residual stresses could be reduced while significantly improving the system mechanical stability. Moreover, the heat transfer may be enhanced especially along the interface direction which would increase the system efficiency. ; This work was supported by Spanish project RTI2018-095052-B-I00, Ministerio de Ciencia, Innovacion y Universidades, Spain (MCIU/AEI/FEDER, UE).

A search for dark matter linelike signals iss performed in the vicinity of the Galactic Center by the H.E.S.S. experiment on observational data taken in 2014. An unbinned likelihood analysis iss developed to improve the sensitivity to linelike signals. The upgraded analysis along with newer data extend the energy coverage of the previous measurement down to 100 GeV. The 18 h of data collected with the H.E.S.S. array allow one to rule out at 95% C.L. the presence of a 130 GeV line (at l=-1.5°, b=0° and for a dark matter profile centered at this location) previously reported in Fermi-LAT data. This new analysis overlaps significantly in energy with previous Fermi-LAT and H.E.S.S. RESULTS: No significant excess associated with dark matter annihilations was found in the energy range of 100 GeV to 2 TeV and upper limits on the gamma-ray flux and the velocity weighted annihilation cross section are derived adopting an Einasto dark matter halo profile. Expected limits for present and future large statistics H.E.S.S. observations are also given. ; The support of the Namibian authorities and of the University of Namibia in facilitating the construction and operation of H.E.S.S. is gratefully acknowledged, as is the support by the German Ministry for Education and Research (BMBF), the Max Planck Society, the German Research Foundation (DFG), the French Ministry for Research, the Centre National de la Recherche Scientifique-Institut National de Physique Nucléaire et de Physique des Particules and the Astroparticle Interdisciplinary Programme of the Centre National de la Recherche Scientifique, the United Kingdom Science and Technology Facilities Council (STFC), the Institute of Particle and Nuclear Physics of the Charles University, the Czech Science Foundation, the Polish Ministry of Science and Higher Education, the South African Department of Science and Technology and National Research Foundation, and the University of Namibia.
