Investigation of the garnet-perovskite transition in Nd doped YIG by means of m...
Hernández-Gómez, P.; Francisco, C. de; Torres, C.; Iñiguez, J.; Raposo, V.; Perdigão, J. M.; Ferreira, A. R.The garnet-perovskite transition is studied in this work with magnetic disaccommodation on polycrystalline Nd doped YIG samples Y3-xNdxFe5O12 (0 < x < 2.5). A very different behaviour with the sintering atmosphere is observed. The results of magnetic disaccommodation for samples sintered in air reveal that the low temperature peak of YIG at 120 K disappear and another peak emerge at 300 K with x = 2.0, when the...
Structuring a clinical information system for hospital services: BASELINE.
Oliveira, A G; Instituto de Biomatemática e Informática da Faculdade de Medicina de Lisboa e CISED.; Raposo, V D; Azevedo, A P; Salgado, N C; Almeida, IClinical database systems have been in use since 1972, but they still fail to meet most of the requirements they were aimed at. This includes not only the management of administrative tasks, but particularly the support of medical activities. Our study presents an experimental model of a clinical database system for general hospitals, mainly dedicated to the support of some basic, fundamental clinical activitie...
