Mechanistic understanding of food effects: water diffusivity in gastrointestinal tract is an important parameter for the prediction of disintegration of solid oral dosage forms
(American Chemical Society, 2013-04)
Much interest has been expressed in this work on the role of water diffusivity in the release media as a new parameter for predicting drug release. NMR was used to measure water diffusivity in different media varying in ...
A fully adaptive numerical approximation for a two-dimensional epidemic model with nonlinear cross-diffusion
An epidemic model is formulated by a reaction-diffusion system where the spatial pattern formation is driven by crossdiffusion. Whereas the reaction terms describe the local dynamics of susceptible and infected species, ...
Self-Replication of Localized Vegetation Patches in Scarce Environments
Desertification due to climate change and increasing drought periods is a worldwide problem for both ecology and economy. Our ability to understand how vegetation manages to survive and propagate through arid and semiarid ...
Intermediate-range structure in ion-conducting tellurite glasses
(Europhysics Letters, 2013-08)
We present ac conductivity spectra of telluritie glasses at several temperatures. For the first time, we report oscillatory modulations at frequencies around MHz. This effect is more pronounced the lower the temperature, ...
SELF-SIMILARITY, SYMMETRIES AND ASYMPTOTIC BEHAVIOR IN MORREY SPACES FOR A FRACTIONAL WAVE EQUATION
(Khayyam Publ Co IncAthensEUA, 2012)
The role of reconnection diffusion in the gravitational collapse of turbulent cloud cores
(International Astronomical UnionFlorianópolis, 2013)
For a molecular cloud clump to form stars some transport of magnetic flux is required from the denser, inner regions to the outer regions of the cloud, otherwise this can prevent the collapse. Fast magnetic reconnection ...
Low-coverage heteroepitaxial growth with interfacial mixing
(IOP Publishing, 2015-01)
We investigate the influence of intermixing on heteroepitaxial growth dynamics, using a two-dimensional point island model, expected to be a good approximation in the early stages of epitaxy. In this model, which we explore ...
