Bubble growth in a two-dimensional viscoelastic foam [PDF]
, 2006 The effects of viscoelasticity on the expansion of gas bubbles arranged in a hexagonal array in a polymeric fluid are investigated. The expansion is driven by the diffusion of a soluble gas from the liquid phase, and the rate of expansion is controlled ...

Free-Stall Use and Preferences in Dairy Cows: A Case Study on Neck Rails Covered by Foam
Animals, 2019 This study tested the effect of neck rails equipped with and without foam on stall usage and preference by dairy cows. The hypothesis of the experiment, that cows prefer lying stalls with foam in comparison to stalls without foam, was rejected. There was
