Coping with geometric discontinuities in porous shallow water models [PDF]
arXiv, 2023 Porosity-based models are a viable alternative to classical two-dimensional (2-d) Shallow water Equations (SWE) when the interaction of shallow flows with obstacles is modelled. The exact solution of the Single Porosity (SP) Riemann problem, which is the building block of numerous porosity models solved with the Finite Volume method, exhibits an ...

Regulating Protein Immobilization During Cell‐Free Protein Synthesis in Hyaluronan Microgels
Advanced Biology, EarlyView.Bifunctional microgels carrying a linear DNA template and Ni2+‐activated NTA moieties are used as platform for cell‐free protein synthesis and in situ protein immobilization. By varying the concentration of NTA moieties in the microgels, the amount of GFP‐His immobilized inside the microgel and released to the microgel environment can be regulated ...

Porosities of Mandelbrot Percolation [PDF]
, 2016 We study porosities in the Mandelbrot percolation process. We show that, almost surely at almost all points with respect to the natural measure, the mean porosities of the set and the natural measure exist and are equal to each other for all parameter values outside of a countable exceptional set. As a corollary, we obtain that, almost surely at almost

The effect of contact torques on porosity of cohesive powders [PDF]
Granular Matter, Volume 7, Numbers 2-3, 2005, Pages 139 - 143, 2004 The porosity of uniaxially compacted cohesive powders depends on the applied stress (including gravity). The case, where these stresses are weak, is considered. The compaction results in a porosity which is a function of sliding, rolling and torsion friction.

Impact of pigments on self-compacting concrete
Mokslas: Lietuvos Ateitis, 2011 We describe an impact of using iron oxide pigment on self-compacting concrete (SCC) properties. We have experimented with adding portions of iron oxide pigment from 3% to 6% into cement paste.
