Study of the vibrational spectrum of cuprorivaite.

In this research, after tracing a history of the pigment, the preparation and analysis of samples of Egyptian blue have been reported. The main reactions taking place during its preparation are indicated. X-ray diffractions show that, starting from mixtures of precursors with stoichiometric composition, the product is practically only cuprorivaite. The kind of flux and cristallinity of silica does not seem determining factors for the pigment formation. Infrared and Raman spectra and an assignment of the bands are reported. Impurities ascertained are discussed on the basis on the data available.

Peptic ulcer in migrants. Seven case-reports from Italy.

Migrant workers in Central Europe are reported to suffer from an increased prevalence of both duodenal and gastric ulcer as compared to native population. No information is available, however, as far as Italy is concerned. The Authors have thought of interest to report on 7 cases of peptic ulcer disease occurring in migrant workers in Italy. Patients were young adult males from African or Mediterranean developing Countries. In 5 cases the symptoms of their peptic ulcers began after their arrival in Italy. The etiopathogenesis of peptic ulcer was likely to include an interaction among emotional stress, low income, shift and manual work, cigarette smoking and nonsteroidal antiinflammatory drugs self-administration. This last factor has not been reported in literature. The hypothesis that migrant workers in Italy are a peptic ulcer-prone population needs further confirmation for its clinical and social implications.
