Analgesic management of an eight-year-old Springer Spaniel after amputation of a thoracic limb

Analgesic agents were administered perioperatively to an eight-year-old Springer Spaniel undergoing amputation of its right thoracic limb. The amputation was carried out due to a painful, infiltrative and poorly differentiated sarcoma involving the nerves of the brachial plexus. A combination of pre-emptive and multimodal perioperative analgesic strategies was used; including intravenous (IV) infusions of fentanyl, morphine, lidocaine and ketamine

ATOM-PROBE STUDY OF ALUMINIUM-LITHIUM ALLOYS

We analysed Al-Li based alloys by means of atom-probe. The influence of parameters such as the tip temperature and the pulse fraction on the apparent composition were investigated for an Al-2.7at%Li alloy and for an Al-7.5at%Li-1.2at%Cu alloy. A ternary Al-3.5wt%Li-3.6wt%Mg alloy aged 24h at 190° C was studied. Atom-probe results point out the presence of Mg in the δ' phase

On the development of a 3D tomographic atom-probe

International audienceThe development of a three-dimensional atom-probe relies on the design of a position sensitive detector. The multidetection system that we have developed is based on the use of a 10 × 10 anodes array placed behind two microchannel-plates assembly in a chevron arrangement. The spread of charge between MCP and the multianode is used to derive the position of ions striking the detector. Spatial coordinates can be calculated for multiple and simultaneous time-of-flight events. The procedure that we have used for the derivation of ions positions from charge measurement is given and preliminary results are described. \textcopyright 1993
