1. Um Mecanismo de SeguranÃa com AdaptaÃÃo DinÃmica em Tempo de ExecuÃÃo para Dispositivos MÃveis. / A Security Mechanism With Dynamic Adaptation For Mobile Device
A crescente utilizaÃÃo de dispositivos mÃveis, redes sem fio e aplicaÃÃes mÃveis evidencia a importÃncia da garantia de seguranÃa da informaÃÃo. Esta preocupaÃÃo surge devido aos riscos envolvidos no trÃfego de informaÃÃes sensÃveis por meio sem fio, uma vez que o meio nÃo limita os riscos de ataques, tal como nas redes convencionais. Adicio

2. Generation of Reduced Nicotinamide Adenine Dinucleotide for Nitrate Reduction in Green Leaves 1
An in vivo assay of nitrate reductase activity was developed by vacuum infiltration of leaf discs or sections with a solution of 0.2 m KNO3 (with or without phosphate buffer, pH 7.5) and incubation of the infiltrated tissue and medium under essentially anaerobic conditions in the dark. Nitrite production, for computing enzyme activity, was determined on aliq

3. On the calculation of magnetic fields based on multipole modeling of focal biological current sources.
Spatially restricted biological current distributions, like the primary neuronal response in the human somatosensory cortex evoked by electric nerve stimulation, can be described adequately by a current multipole expansion. Here analytic formulas are derived for computing magnetic fields induced by current multipoles in terms of an nth-order derivative of th

4. Influence of the membrane potential on the free energy of an intrinsic protein.
A modified Poisson-Boltzmann equation is developed from statistical mechanical considerations to describe the influence of the transmembrane potential on macromolecular systems. Using a Green's function formalism, the electrostatic free energy of a protein associated with the membrane is expressed as the sum of three terms: a contribution from the energy req
