    Simulation of Water Flow in Soils Associated with Earth Electrodes

    The electrodes of grounding systems transmit strong electric currents through the soil. The injection of the electric current and establishment of an electric field in the soil mass cause an electro-osmotic fl...

    Age, Growth and Maturity of Red Porgy Pagrus pagrus (Sparidae) from Southeastern Brazil

    Age, growth and length-at-maturity of the red porgy Pagrus pagrus were studied off the southeastern coast of Brazil. A total of 798 otoliths from specimens sampled from the hook-and-line commercial landings betwe...

    Statistical Assessment of Unidirectional Propagation of a Leachate Contamination Plume

    The leachate produced by the Municipal Solid Waste Landfill of São Pedro da Aldeia (State of Rio de Janeiro, Brazil) flows almost entirely in one direction guided by a natural ditch in the bottom of a gentle v...

    Which mechanism underlies the water-like anomalies in core-softened potentials?

    Using molecular dynamics simulations we investigate the thermodynamics of particles interacting with continuous and discrete versions of a core-softened (CS) intermolecular potential composed by a repulsive sh...

    Water at Positive and Negative Pressures

    We review recent results of molecular dynamics simulations of two models of liquid water, the extended simple point charge (SPC/E) and the Mahoney-Jorgensen transferable intermolecular potential with five poin...

    Speed and diffraction efficiency in feedback-controlled running holograms for photorefractive crystal characterization

    We report the measurement of the diffusion length, the Debye screening length and the quantum efficiency of photoelectron generation in strongly light absorbing photorefractive Bi12TiO20 crystals, using fringe-lo...

    Donnan equilibrium and the osmotic pressure of charged colloidal lattices

    We consider a system composed of a monodisperse charge-stabilized colloidal suspension in the presence of monovalent salt, separated from the pure electrolyte by a semipermeable membrane, which allows the cros...
