Effects of long wave ultraviolet radiation on photosensitizing and related compounds. I
The effects of long ultraviolet radiation (UVA) on the fluorescence of twenty‐four photosensitizing and related compounds were studied.

REFORMA DO ESTADO E AS POLÍTICAS PARA A EDUCAÇÃO SUPERIOR NO BRASIL NOS ANOS 90
This article aims at discussing the federal policies for higher education implemented in Brazil in the 1990s. It assumes that such policies are based on socio-political choices and interests linked to the changes occurring in the contemporary Brazilian scene, changes that have deep historical roots, which emerge in the process of reformation of the Brazilian State. This situation implies alterations in the field of public policies, and more particularly in that of social policies, since the on-going official proposals and projects are characterized by a decrease of the role of State. The borders between public and private affairs have become increasingly blurred in a process detrimental to the former. The contradictions in the federal policies for higher education are analyzed here, as well as their results as for the following fields: institutional diversification and differentiation; assessment criteria, broadening and privatization of this level of education.
