1. Effect of porogenic solvent on selective performance of molecularly imprinted polymer for quercetin
Molecularly imprinted polymers (MIP's) for quercetin were successfully synthesized by a thermal polymerization method using quercetin as template molecule, acrylamide as functional monomer and ethylene glycol dimethacrylate as cross-linker in the presence of four different porogenic solvents: 1,4-dioxane, tetrahydrofuran (THF), acetone, and acetonitrile.

3. Condutividade induzida por radiação ionizante no Mylar (PET) e Kapton (polimiidia). / Radiation-induced conductivity in Mylar (PET) and Kapton (polymide)
In this work we present extensive results of measurements of the prompt and delayed radiation-induced conductivity of samples of PET and Kapton. Experimental parameters, such as the effective energy of the radiation, the exposure rate, the total dose, the value of the applied electric field, the nature of the electrodes, and the ambienta1 conditions were cha

4. Regimes dissipativos e coeficientes de transporte não-lineares
Irreversible Thermodynamics is reviewed from a basic standpoint. A phenomenological scheme extending the classical phenomenological approach to transport problems (simultaneous and mutually interfering processes) including Onsager s relations is proposed. Non-linear relations between gradients of intensive quantities (forces) and currents (fluxes) are introd

5. Elementary transition state theory of the Soret and Dufour effects
The elementary transition state approach has been used to obtain a simple model theory for the Soret effect (thermal diffusion) and the Dufour effect. The flow of heat in the Dufour effect is identified as the transport of the enthalpy change of activation as molecules diffuse. The theory as now formulated applies only to thermodynamically ideal mixtures of
