The enteric microbiota is increasingly implicated as a central factor in the development of intestinal inflammation in humans and experimental animals, and the intestinal environment is considered important in both colorectal cancer development and modulation of mucosal immunity. Diet-induced changes in the different populations of the intestinal microbiota can be achieved by use of probiotic bact

Depending on specific configuration and design, a variety of physical phenomena is present in solid oxide fuel cells (SOFCs). These processes include multi-component gas flow, energy and mass transfer of chemical species in composite domains and sites. Due to the electrochemical reactions, generation and consumption of chemical species together with electric current production are involved at the

Direct scattering of propagating transient waves originating from internal sources in non-stationary, inhomogeneous, dispersive, stratified media, is investigated. The starting point is a general, inhomogeneous, linear, first order, 2 × 2 system of equations. Particular solutions are obtained, as integrals of fundamental waves from point sources distributed throughout the medium. First, resolvent

Confronted with a looming crisis of ecological deprivation and global resource depletion, the political response of most liberal regimes has been a complacent wait-and-see attitude, at best combined with piecemeal environmental reforms and moral support for international initiatives such as the Kyoto Treaty. Meanwhile, the theoretical discourse on sustainability seems to be oscillating between the

When concatenated coding schemes operate near channel capacity their component encoders may operate above capacity. The decoding bit-error performance of binary convolutional codes near and above capacity is investigated

Solid oxide fuel cells (SOFCs) are promising candidates for future energy systems due to their ability to use renewable fuels and that they are energy efficient. A fully coupled two-dimensional computational fluid dynamics (CFD) model based on the finite element method (using COMSOL Multiphysics) is developed to describe an intermediate temperature SOFC single cell. Governing equations for various
