DOI: 10.1007/s00397-019-01167-7
Abstract: Several cases of vermiculation formation have been reported in painted caves, with potential issues for the conservation of parietal prehistoric paintings. Vermiculations are natural patterns observed in caves. They result from displacement of sediment initially… read more here.

DOI: 10.1007/s00397-019-01173-9
Abstract: We report that aqueous solutions of high molecular weight chitosan display a regime of shear thinning at low shear rates that is consistent with the existence of an apparent yield stress. The concentration-dependent scaling of… read more here.
