´´Synthesis and Antimicrobiana Activity of 3-trifluormetil (oxo) - pirimido [1,2 it] benzimidazóis`` - Simone Schneider Amaral
This work presents the synthesis of a series of 3-trifluormethyl(oxo)-pyrimido[1,2-a]benzimidazoles from the cyclocondensation reaction between 2-amino-1H-benzimidazol and 4-alcoxy-1,1,1-trihalo-3-alquen-2-ones.The obtaintion of the 3-trifluormethyl-pyrimido[1,2-a]benzimidazoles were regioespecific and the yields were, in general, very good.On the other hand, the synthesis of 3-oxo-pyrimido[1,2-a]benzimidazoles were not always regioespecific.

OCUPAÇÃO ANTRÓPICA E SÓCIO-AMBIENTAL NA ÁREA DE CAPTAÇÃO DO RESERVATÓRIO DO DNOS SANTA MARIA- RS. - Jurandi Zanoti Goldani
The present research has as objective accomplishes a study of the environmental impact provoked by the anthropic progress on the native vegetation, in order to identify the permanent preservation areas (PPA) like hillsides of hills, ciliary's forests and ofter subsidies for its preservation.The more intense man's intervention in the environment through the natural resources, especially forests, rivers and areas of permanent preservation are a consequence of the technological progress and the population growth that we have been verifying along the time.
