A high strength steel pipe for an airbag system has a steel composition comprising C: 0.05 - 0.20 %, Si: 0.1 - 1.0 %, P: at most 0.025 %, S: at most 0.010 %, Cr: 0.05 - 1.0 %, Al: at most 0.10 %, at least one of Ti and Mn satisfying (1) Ti <= 0.02% and (2) 0.4% <= Mn + 40Ti <= 1.2%, and a remainder of Fe. The composition may further include one or more of (i) at least one of Mo: 0.05 - 0.50 %, Ni: 0.05 - 1.5 %, V: 0.01 - 0.2 %, and B: 0.0003 - 0.005 %, (ii) at least one of Cu: 0.05 - 0.5 % and Nb: 0.003 - 0.1 %, and (iii) at least one of Ca: 0.0003 - 0.01 %, Mg: 0.0003 - 0.01 %, and REM: 0.0003 - 0.01 %. The steel pipe can be manufactured by forming a pipe from the above-described steel composition to obtain prescribed dimensions, heating to at least the Ac, transformation point and quenching, and then tempering at the Ac, transformation point or below.
Méthode d'analyse de la fonction physiologique d'une substance cible par inactivation de la fonction physiologique de ladite substance cible. Cette méthode consiste (a) à lier un composé optiquement actif représenté par la formule (I), dans laquelle Q représente un groupe de liaison de ce composé à la substance cible, à la substance cible pour former un complexe contenant la substance cible et le composé optiquement actif, et (b) à exposer à un rayonnement lumineux le complexe ainsi obtenu pour inactiver la fonction de la substance cible à laquelle le composé optiquement actif a été lié, ou inactiver la fonction de la substance cible sur le site auquel le composé optiquement actif a été lié.
