Abstract: The benchmark problem 4 (the FELIX brick) defined in the International Workshops for Eddy Current Code Comparison is solved by 11 different computer codes. This problem is time‐dependent and three dimensional eddy current problem with a hole. 13 sets of results in total are presented. The results are in fairly good agreement although the formulations and methods in the codes are different from each other. The problem of the hole (multi‐connectivity) is successfully solved in the results.

Abstract: Ultraporous fired bricks (porosities from 56 to 72%) were developed from materials locally available in Nigeria The grog particle size was used to modulate the porosity of the bricks The porous bricks produced were then employed as supports for the immobilization of a yeast strain isolated from a local alcoholic beverage, palm wine The influence of a brick's porosity and particle size on the cell-loading capacity and cell growth inside the fired brick support were studied The study revealed that a brick's porosity varied linearly with the mean particle size of the grog, increasing from a porosity of 56% at a particle size of 0805 mm to 72% at a particle size of 0075 mm Cell saturation of the surface area available within the support matrix was completed within four hours of contact between the cell and the adsorbing surface especially for the most porous samples Cell growth was therefore not observed in such cases; however, the less porous samples supported some cell growth upon incubation Cell holdup was also observed to increase exponentially when either the porosity was increased or the particle size was decreased The influence of particle size, however, became insignificant at very high porosities
