13. Estudo das caracteristicas de inflamabilidade de polimeros utilizados na construção civil e industria de transportes / Study of flammability characteristics of polymers used in buildings and automobile industry
The polymer materials are being used in several applications. The great number of existent monomers, as well as the possibility of copolymers synthesis, polymeric alloys formulation and the composites and nanocomposites show that it is possible to obtain materials with different specific properties and for being used in different application areas. However,

15. Estudo da incorporação de resíduo industrial polimérico ao CAP
This work presents the incorporation of an industrial polymeric waste into a petroleum asphalt cement with penetration grade 50-60 (CAP 50-60). The main goal of this research is the development of a polymer-modified asphalt, with improvements in its physical properties, in order to obtain a more resistant material to the traffic loads. Furthermore, the use o

16. Fatty Acids in the Genus Bacillus II. Similarity in the Fatty Acid Compositions of Bacillus thuringiensis, Bacillus anthracis, and Bacillus cereus1
The nature and relative abundance of fatty acids produced by two strains each of Bacillus thuringiensis and of B. anthracis were studied by gas-liquid chromatography on a 12,000 theoretical plate polyester column capable of partially resolving iso- and anteiso-fatty acids with the same number of carbon atoms. Unsaturated fatty acids as the bromo derivatives
