13. Recent NMR techniques applied to protein-ligand interactions and metabonomics / Tecnicas de RMN recentes aplicadas as interações proteina-ligante e a metabonomica
Durante as últimas décadas, muitos métodos de RMN de H foram desenvolvidos e aplicados para triagem e caracterização de interações intermoleculares e para a metabonômica. Estes são temas recentes da RMN e ambos serão abordados em dois capítulos distintos neste trabalho. No Capítulo 1 foi realizada a implantação e otimização de técnicas de RM

14. Caracterização espectroscópica e cromatrográfica de copoliésteres biodegradáveis
The recycling of poly(ethylene terephthalate) (PET) can be carried through by different techniques, one of them is the chemical recycling, where new aliphatic-aromatic copolymers are synthesized from melt reaction of the PET post-consumer with aliphatic homopolymers. The aliphatic polyesters, such as the poly(ethylene adipate) (PEA) are biodegradable. The sy

15. Efeitos biológicos da peçonha da aranha Parawixia bistriata em ratos: isolamento e caracterização química parcial de uma neurotoxina pró-convulsivante / Biological effects of the Parawixia bistriata spider venon in rats: isolation and partially chemical characterization of a convulsant neurotoxin.
Arthropod venoms are rich sources of neurotoxins, molecular tools with selective and specific actions over the mamalian central nervous system with great clinical and scientific importance. Previous work of our laboratory showed that the spider venom of Parawixia bistriata, when injected by intracerebroventricular (i.c.v.) route, induced convulsive seizures

16. Obtainion and characterization of absorbent materials throught carboximelation of etanol/water pulp non fiber fraction sugar cane bagasse. / Obtenção e caracterização de materiais absorventes através de carboximetilação de polpa etanol/água de medula de bagaço de cana de açúcar.
This work describes the use of ethanol / water pulps of pith in a study aiming the obtention and characterization of substantially insoluble carboxymethylcellulose for application as an absorvente material. In a typical experiment the carboxymethylation reaction of bleached ethanol / water pulp occurred at 80°C for 4 hours in isopropanol/ water suspensio

17. Polpação acetosolv de bagaço de cana e madeira de eucalipto
Acetosolv pulping of sugar cane bagasse and Eucalyptus grandis wood was studied with the objective to make adequate the conditions of this process for national feedstocks and to promote the integral use of lignocellulosic materials. The pulping of extracted and depithed sugar cane bagasse (8.0% humidity, 1.2% ash, 22.7% lignin and 53.2% cellulose) and eucaly
