They concluded that the obtained stressing rate was consistent with magma intrusion into a vertical dyke rather than ground water diffusion.
Using that capacitary positive improving property and two new inequalities for generalized Ornstein Uhlenbeck generators, we show the essential self-adjointness of the ground state diffusion generator Lφ=L+2Γ/φ associated with two dimensional Euclidean quantum fields.
Fractional calculus and fractional differential equations are popular in describing anomalous diffusion, ground water flow and transport, and the price fluctuation in finance, etc.
The increase of particle size provides longer and more effective ground for heat diffusion through each nanoparticle, while the increase of concentration increases the volume of the highly conductive solid available for heat transfer in the nanofluid.
At high temperatures, this complex can be broken by crossing a 1.5 eV barrier, leading to a state ∼0.8 eV higher than the ground state, allowing diffusion of the vacancy.
Since no significant change in litter composition occurred with distance to the trunk base and in the absence of stemflow reaching the ground during showers, diffusion of bark tannins from buried parts of the trunk and main lateral roots were suspected to negatively influence soil biological activity, particularly earthworm activity.
The survey was grounded in the Diffusion of Innovations theory (Rogers, 2003), which identifies new ideas that are adopted early by innovators and early adopters.
In contrast to static models, hydrodynamic models combine geochemical reactions with hydrogeological processes such as ground-water flow, diffusion and dispersion.
Assuming a simple one-dimensional thermal diffusion, the ground temperature variation ΔT (z, t) is expressed as: where Δ T0 is the temperature variation amplitude at the surface, ω = 2π yr−1 is the angular frequency, and where κ is the thermal diffusivity.
It is known that cyanide produced in the soil is usually associated with various metal ions, allowing for its rapid mobility in the ground water and subsequent diffusion in the atmosphere [8].
