ABSTRACT
The infrared and Raman spectra of the two hydrates of strontium oxalate, SrC2O4â H2O and SrC2O4â 2H2O, were recorded and discussed on the basis of their structural peculiarities and in comparison with the spectra of the related calcium oxalates and other previously investigated metallic oxalates.

The infrared and Raman spectra of synthetic moolooite, Cu(C2O4).nH2O, were recorded and analyzed on the basis of its structural characteristics and by comparison with related species. The thermogravimetric analysis of the investigated samples show that the water content n, was equal to 0.2. The electronic (reflectance) spectrum of the complex was also recorded and briefly discussed.

Este trabalho teve como objetivo verificar a qualidade de vida de pacientes com doenças crônicas e diabete mellitus e foi baseado nas conceitualizaçöes do termo qualidade de vida proposta por Wenger et al (1984). Para esses autores, a qualidade de vida pode ser medida com base na capacidade funcional, nas percepçöes e sintomas dos indivíduos em condiçöes crônicas de saúde. A amostra consistiu de 94 pacientes, sendo 35 com doenças cardiovasculares fazendo tratamento em unidades de internaçäo e ambulatorial (GRUPO I), 29 pacientes com doenças cardiovasculares em reabilitaçäo específica (GRUPO II), e 30 pacientes com diabetes mellitus em tratamento ambulatorial (GRUPO III). Os dados foram coletados utilizando-se o questionário McMaster Health Index desenvolvido por Chambers (1984). Em síntese, os resultados mostraram que em relaçäo a funçäo física, percepçäo quanto à saúde e satisfaçäo com a vida, os pacientes do GRUPO II tiveram qualidade de vida melhor do que os pacientes do GRUPO I e do GRUPO III.
