A socio-ecological perspective on alcohol use in adolescence
Alcohol use among adolescents has become a public health problem(Morawska & Oei,2005). Although the frequency and the amount of alcoholic beverages consumed vary greatly from different countries and cultures, in two thirds of the ESPAD countries the vast majority of the students (15-16 years) have drank alcohol at least once in their lifetime. Moreover, in half of the participating countries, 47% of the students had consumed at least one glass of alcohol at the age of 13 or younger, and 14% had been drunk at that age. These changing patterns of consumption are associated with a variety of negative outcomes (Coleman & Cater, 2003). In a socio-ecological perspective, many studies (Nation & He…
FIRST experiment: Fragmentation of Ions Relevant for Space and Therapy
International audience; Nuclear fragmentation processes are relevant in different fields of basic research and applied physics and are of particular interest for tumor therapy and for space radiation protection applications. The FIRST (Fragmentation of Ions Relevant for Space and Therapy) experiment at SIS accelerator of GSI laboratory in Darmstadt, has been designed for the measurement of different ions fragmentation cross sections at different energies between 100 and 1000 MeV/nucleon. The experiment is performed by an international collaboration made of institutions from Germany, France, Italy and Spain. The experimental apparatus is partly based on an already existing setup made of the …
