(Jackson & Fersht, 1991a,b; Jackson et al., 1993a,b) have established that CI2 folding and unfolding can be modeled by simple two-state kinetics. The structure of the transition state for this protein has been extensively characterized by protein engineering (Itzhaki et al., 1995; Otzen & Fersht, 1995; Jackson & Fersht, 1991b), by free energy functional approaches (Shoemaker & Wolynes, 1999; Shoemaker et al., 1999), by a geometrical variational principle (Micheletti et al., 1999), and by…

moléculas podem ter uma estrutura linear ou ramificada (termoplásticos) ou pode formal uma rede tridimensional (termorígidos). Polímeros Termoplásticos É aquele que derrete e flui quando aquecido, ao contrário dos termorígidos. Thermoplastic polymers are usually not highly crosslinked , and act much like molecular solids: low melting and boiling points, low strength, ductile and the like. Polímeros termoplásticos geralmente não são altamente reticulado , e agem como sólidos…

source, and low cost besides presenting colorimetric properties compatible with the carbon black. Regarding the irradiated samples can be said that there was an increase in the majority of properties studied. Depending on the intended use of the polymer can irradiate it in the most appropriate dose which had improvement in their properties. 8 SUMÁRIO 1 INTRODUÇÃO..........................................................................................................13 2 OBJETIVOS........
