In order to explore the extent to which interactions between pairs of species embedded in complex multispecies food webs are nonlocalized, in terms of the number of other species that need to be taken into account, the influence of other species in the system on the response of the hake fishery to a cull of fur seals is calculated in a 29-species food ...

Dopant diffusion in silicides: Effect of diffusion paths
Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1992While dopants implanted in well annealed WSi2 show no lattice diffusion and only limited grain-boundary diffusion at temperatures up to 900 °C, on the contrary, rapid diffusion is observed at temperatures as low as 300 °C when the implantation takes place in the as-deposited amorphous silicide.

Cross Diffusion-Stresses Effects
Defect and Diffusion Forum, 2007Three cross diffusion-stresses effects are considered: mobility-stress effect, flux-stress effect and vacancy-stress effect. The value of the migration volume for vacancies in Al is found from atomistic computer simulation. A cross vacancy-stress effect is applied to the process of the pores growth and dissolution in Ni-based superalloys.

Modeling of Effective Moisture Diffusivity in Corn Tortilla Baking.
Journal of Food Science, 2018The objective of this work was to model the mass transfer in corn tortilla baking using different approaches for effective diffusivity based on the Fick's law of diffusion and to evaluate the impact of the process on quality parameters.

Effects of differential diffusion on unsteady diffusion flames
International Communications in Heat and Mass Transfer, 1998The effects of differential diffusion on unsteady diffusion flames are considered for one-dimensional geometries. A Stefan problem is obtained for a single planar flame separating two semi-infinite regions containing fuel and oxidizer. Non-unity diffusivity ratio and the stoichiometry affect strongly the flame evolution and determine the conditions to ...

Holographic diffusers: polarization effects
Optical Engineering, 1994In some applications of diffusers, it-is desirable to minimize the diffuse back reflection of light. Use of polarized light is one way to reduce this back reflection. To that end, the effect of diffusers on polarized light is studied experimentally. Diffusers based on ground glass, white plastic containing scatterers, and holographic optical elements ...

Absorption effects in diffusing wave spectroscopy
Applied Optics, 2014The effect of absorption in diffusing wave spectroscopy (DWS) was studied using an absorption-dependent diffusive equation for describing the light propagation within a turbid liquid where dielectric microspheres have been embedded. Here, we propose an expression for the time-averaged light intensity autocorrelation function that correctly describes ...

Thin Solid Films, 1975
Abstract Small additions of solutes to ionic substances can produce drastic changes in diffusion rates and ionic conductivities and these effects, dominated by the requirements of charge compensation, are very well understood and regularly employed in studies of such materials.

Inertial effects in diffusion-limited reactions
Journal of Physics: Condensed Matter, 2010Diffusion-limited reactions are commonly found in biochemical processes such as enzyme catalysis, colloid and protein aggregation and binding between different macromolecules in cells. Usually, such reactions are modeled within the Smoluchowski framework by considering purely diffusive boundary problems.
