Measurements of the nuclear modification factor for jets in Pb+Pb collisions at sNN =2.76TeV with the ATLAS detector

Measurements of inclusive jet production are performed in pp and Pb+Pb collisions at sNN−−−√=2.76 TeV with the ATLAS detector at the LHC, corresponding to integrated luminosities of 4.0 pb−1 and 0.14 nb−1 , respectively. The jets are identified with the anti-kt algorithm with R=0.4, and the spectra are measured over the kinematic range of jet transverse momentum 32nuclear modification factor, RAA, is evaluated and jets are found to be suppressed by approximately a factor of two in central collisions compared to pp collisions. The RAA shows a slight increase with pT and no significant variation with rapidity.

Ressonância nuclear magnética no diagnóstico de pseudoaneurisma de ventrículo esquerdo. Antigo problema, nova opção

Paciente feminina, 67 anos, internada por infarto agudo do miocárdio de parede lateral, com edema agudo de pulmão e evolução para choque cardiogênico nas primeiras horas. Ecocardiograma transesofágico e ressonância nuclear magnética confirmaram o diagnóstico de pseudoaneurisma de ventrículo esquerdo. A paciente foi submetida a tratamento cirúrgico com sucesso.
