Segregation in desiccated sessile drops of biological fluids

It is shown here that concurrence between advection and diffusion in a drying sessile drop of a biological fluid can produce spatial redistribution of albumen and salt. The result gives an explanation for the patterns observed in the dried drops of the biological fluids.Comment: 6 pages, 3 figures; submitted to European Physical Journal

An investigation of site-bond percolation on many lattices

A calculation of site-bond percolation thresholds in many lattices in two to five dimensions is presented. The line of threshold values has been parametrized in the literature, but we show here that there are strong deviations from the known approximate equations. We propose an alternative parametrization that lies much closer to the numerical valuesComment: LaTeX, 14 pages, 6 figures, 5 tables, submitted to Int. J. Mod. Phys.

On Site Percolation on Correlated Simple Cubic Lattice

We consider site percolation on a correlated bi-colored simple cubic lattice. The correlated medium is constructed from a strongly alternating bi-colored simple cubic lattice due to anti-site disordering. The percolation threshold is estimated. The cluster size distribution is obtained. A possible application to the double 1:1 perovskites is discussed.Comment: 10 pages, 12 figures, Submitted to IJMP
