The main mechanism for water recruitment was believed by passive diffusion 30 years ago.
Over half a century ago, Turing first proposed the reaction-diffusion mechanism as the basis for self-organization and pattern formation in biological systems [1].
Despite its equatorial location, Mr. Chrétien says, "the region is blessed with good climate, is rich with diverse soils and plants, and has prospered thanks to some strong basic techniques: the association of cattle keeping and agriculture; the diffusion of the banana a millennium ago; and the mastery of iron metallurgy two millennia ago".
A new concept for the enclosure-acoustic prediction derived from the mathematical theory of diffusion was proposed some years ago [J. Picaut et al., Acustica 1997].
The system was designed decades ago as a way to ensure the timely diffusion of information in case of natural disasters or to broadcast the rare state ceremony.
Diffusion damping took place about 13.8 billion years ago, during the stage of the early universe called recombination or matter-radiation decoupling.
In vitro, diffusion methods for topical agents were proposed 30 years ago but did not encountered the success of the Kirby-Bauer method applied to antibiotics.
More than 80 years ago, Krogh [ 1] published the first oxygen transport model that described diffusion of oxygen from a single capillary cross-section into the surrounding cylinder of tissue.
The reaction-diffusion mechanism presented by A. M. Turing more than 60 years ago is the most common theoretical model for explaining various examples of biological pattern formation, including pigment patterning (Kondo and Miura, 2010; Meinhardt, 1982; Murray, 2002; Turing, 1952).
Approximately a decade ago a new concept to describe the kinetics of one-phase solid state systems evolving by diffusion and activity of vacancies has been published by the authors.
Bulk, Knudsen and surface diffusion will be handled using a unified, consistent, approach, borrowing ideas and concepts developed more than a century ago by James Clerk Maxwell and Josef Stefan.
