Some Demographic and Economic Characteristics of Practitioners

1994

Les donnees presentees ici sont extraites d'une grande enquete realisee en Mars 1990 aupres des praticiens espagnols. On a travaille sur un echantillon stratifie tire au hasard. L'essentiel des conclusions touche a la jeunesse de ce groupe professionnel et a l'existence de discriminations dues au sexe pour ce qui est des conditions de travail et des avantages economiques. Il existe des differences frappantes entre les diverses specialites en ce qui concerne les heures de travail, le type d'organisations qui les accueillent, le salaire et l'assujetissement fiscal. Les demissions sont essentiellement dues a des raisons d'ordre economique. Une profession n'existe que si elle est pourvue d'un s…

The ALICE Collaboration

2009

The production of mesons containing strange quarks (KS, φ) and both singly and doubly strange baryons ( , , and − + +) are measured at mid-rapidity in pp collisions at √ s = 0.9 TeV with the ALICE experiment at the LHC. The results are obtained from the analysis of about 250 k minimum bias events recorded in 2009. Measurements of yields (dN/dy) and transverse momentum spectra at mid-rapidity for inelastic pp collisions are presented. For mesons, we report yields (〈dN/dy〉) of 0.184 ± 0.002(stat.) ± 0.006(syst.) for KS and 0.021 ± 0.004(stat.) ± 0.003(syst.) for φ. For baryons, we find 〈dN/dy〉 = 0.048 ± 0.001(stat.) ± 0.004(syst.) for , 0.047 ± 0.002(stat.) ± 0.005(syst.) for and 0.0101 ± 0.0…
