Konferensbidrag (refereegranskat)abstract
- A silicon-tungsten imaging calorimeter has been designed, built and successfully integrated in the PAMELA satellite-bome apparatus. The main physics task of the experiment is the measurement of the flux of antiprotons, positrons and light nuclei in the cosmic radiation. The purpose of the calorimeter is to separate antiprotons and positrons from the vast background of cosmic-ray electrons and protons, respectively. In this work we present the identification capabilities of the calorimeter obtained using both Monte Carlo and test beam data. We show that the calorimeter can provide a proton rejection factor of about 105 while keeping a similar to 90% efficiency in selecting electrons and positrons. The PAMELA calorimeter is therefore able to provide the identification power needed to reach the primary scientific objectives of PAMELA.

Tidskriftsartikel (refereegranskat)abstract
- The competitiveness, in terms of macro and micro levels of an enterprise, is often dictated by its capacity to innovate, ability to respond to the needs of the market, and resilience to challenges from competition. This paper reviews the literature on the adaptation of research and development (R&D) units in subsidiaries of multinational corporations. It focuses mainly on the impact of the technological dynamic on sustainability performance of the Brazilian subsidiary of the Swedish multinational Ericsson. Through a conceptual framework, it explores information and communication technologies (ICT) towards a transversal and comprehensive vision of levels of innovation and sustainability.
