The time-domain version of the optical theorem is discussed. The theorem relates the sum of the scattered and absorbed energies, for a plane pulse that is scattered from a bounded obstacle, to the far-field amplitude in the forward direction. Several fundamental results concerning the scattered and absorbed energies that follow from the theorem are discussed.
Workpackage 8 of the European Datagrid project was formed in January 2001 with representatives from the four LHC experiments, and with experiment independent people from five of the six main EDG partners. In September 2002 WP8 was strengthened by the addition of effort from BaBar and D0. The original mandate of WP8 was, following the definition of short- and long-term requirements, to port experim
This text makes the point that we cannot understand civic agency - people's taking on the role of acting as citizens - in a vacuum. The notion of encompassing civic cultures is introduced to analylically anchor civic agency in the horizons of everyday life, practices, and identity

Beta-decay half-lives and delayed-neutron emission probabilities of the neutron-rich noble-gas isotopes 94-99Kr and 142-147Xe have been measured at the PSB-ISOLDE facility at CERN. The results are compared to QRPA shell-model predictions and are used in dynamic calculations of r-process abundances of Kr and Xe isotopes.
Sustainable development was defined by the Bruntland Comission as a 'development that meets the needs of the present without compromising the ability of future generations to meet their own needs' (WCED1 , 1987, p. 8). In the report 'Our Common Future' the Bruntland Commission proposed policies for a 'World Programme for Change' (WCED, 1987). At the UNCED2 , conference in Rio 1992, proposals were
The Augustan poet Ovid (43 BC – AD 17/18) is mentioned by Seneca the elder for his oratorical skills as a school boy. If we are to believe Seneca, Ovid excelled to such a degree that he even surpassed his teachers. He took special interest in exercises concerning ethos, and is said to have transferred what he learned into his own verse. The influence from rhetorical training is indeed visible in
ForcePAD is an intuitive tool for visualising the behavior of structures subjected to loading and boundary conditions. The design of the user interface aims to be as intuitive as a standard image processing software. Users should be able to design structures, apply and boundary conditions and visualise results without knowledge of the underlying nite element model.
