Crystal growth of strontium chloroapatite (Sr5(PO4)3Cl) doped with manganese(V) and study of the absorption spectrum

Single crystals of Sr5(PO4)3Cl doped with Mn(V) ion were prepd. by the std. flux-growth technique. The polarized electronic spectrum (8000-44,000 cm-1) of MnO43- in Sr5(PO4)3Cl was measured at 4.2 K. By means of a careful examn. of the possible excited states and of the site-symmetry of the Mn(V) ion, the bands in the region 8000-23,000 cm-1 are assigned as ligand-field transitions and the others at higher energy, which are more intense, as charge-transfer transitions. These assignments are based on the obsd. polarizations of the bands and on their oscillator strengths

La valutazione ecografica nella sindrome conflittuale della spalla : studio su 6.496 casi

Viene presentato uno studio ecografico della cuffia dei muscoli rotatori della spalla con l\u2019obiettivo di puntualizzare la metodica di studio, i quadri ecografici significativi per patologia della cuffia e concludere con la puntualizzazione della validit\ue0 dello screening ecografico. Sono state studiate 6.496 spalle consecutive, dallo stesso esaminatore con differenti apparecchi ecografici, seguendo sempre la stessa metodica con l\u2019apporto originale di alcune scansioni e misurazioni dello spazio subacromiale; i soggetti erano sempre inviati con sospetto diagnostico di patologia della cuffia dei rotatori. Il 35,14% delle spalle \ue8 risultato normale, il 21,42% presentava edema e flogosi, il 15,73% tendinopatia cronica (di cui il 55,47% con rotture parziali di cuffia), il 27,81% rotture complete di cuffia (di cui 29,27% rotture massive). L\u2019ecografia ha confermato essere, in mani esperte, esame accurato, specifico e sensibile nella diagnostica delle patologie della cuffia dei rotatori, non certamente disgiunto da un\u2019accurata e precisa valutazione clinica e radiografica
