Interatomic Coulombic decay following the Auger decay: Experimental evidence in rare-gas dimers
Interatomic Coulombic decay (ICD) in Ar(2), ArKr and Kr(2) following Ar 2p or Kr 3d Auger decay has been investigated by means of momentum-resolved electron-ion-ion coincidence spectroscopy. This sequential decay leads to Coulombic dissociation into dication and monocation. Simultaneously determining the kinetic energy of the ICD electron and the kinetic energy release between the two atomic ions, we have been able to unambiguously identify the ICD channels. We find that, in general, spin-conserved ICD, in which the singlet (triplet) dicationic state produced via the atomic Auger decay preferentially decays to the singlet (triplet) state, transferring the energy to the other atom, is faster than spin-flip ICD, in which the Auger final singlet (triplet) dicationic state decays to the triplet (singlet) state. However, spin-flip ICD may take place when spin-conserved ICD becomes energetically forbidden. Dipole-forbidden ICDs from Kr(2+)(4s(-2) (1)S)-B (B = Ar or Kr) to Kr(2+)(4p(-2) (1)D, (3)P)-B(+) are also observed. (c) 2008 Elsevier B.V. All rights reserved

Ruptura do ligamento cruzado cranial em um gato: reconstituição com fáscia lata Cranial cruciate ligament rupture in a cat: reconstitution with fascia lata
Em gatos, a ruptura do ligamento cruzado cranial (RLCC) trata-se de diagnóstico raro e a correção cirúrgica propicia o retorno mais rápido à função do membro. Foi atendida, no Hospital Veterinário da Universidade Federal de Santa Maria (UFSM), uma gata apresentando claudicação aguda e dor à palpação do joelho direito. O diagnóstico de RLCC foi realizado através dos testes de compressão tibial e gaveta cranial positivos e confirmado na cirurgia. Optou-se por realizar a reconstituição do ligamento com fáscia lata e, após achados clínicos pós-operatórios e em longo prazo concluiu-se que a técnica apresentou resultados satisfatórios neste caso.<br>The cranial cruciate ligament rupture (CCLR) is rare diagnosis in cats and the surgical correction provides a faster return to limb function. A cat with acute lameness and pain on palpation of the right stifle was attended at the Veterinary Hospital of UFSM. The diagnosis of CCLR was performed by positive tibial compression test and positive cranial drawer sign and confirmed by surgery. We chose to perform the reconstruction of the ligament with fascia lata and after of the observe clinical postoperative and in the long-term it was concluded that the technique showed satisfactory results in this case
