A theory for the propagation of light through a randomly scattering slab is developed that does not take advantage of a diffusion approximation but can be solved analytically. The treatment allows for scattering anisotropy and boundary reflectivity to be incorporated in a straightforward fashion...

On the basis of a microscopic Hamiltonian on a semi-infinite cubic lattice, we derive the excess surface free energy for a confined ternary mixture of oil, water and amphiphile. Using the standard mean-field approximation for a spin-1 model we calculate the surface parameters in terms of the...

We propose a novel method to obtain averaged interface curvature of complex fluids from their scattered intensity without reference to any specific models. The averaged interface curvature of binary mixtures undergoing spinodal decomposition can be obtained with this method. It was found that...

We demonstrate with the aid of visual investigations that multiply reentrant liquid–liquid transitions can be obtained in ethyl alcohol (E)–water (W) mixtures, by the addition of ions. Multiplicity of reentrance can be tuned by changing the concentration, size, or the structure forming...

The occurrence of swarms of small bubbles in a variety of industrial systems enhances their performance. However, the effects that size polydispersity may produce on the stability of kinematic waves, the gain factor, mean bubble velocity, kinematic and dynamic wave velocities is, to our...

Brazil has the largest stock market in South America; Argentina has one of the smallest. We investigate the spread relationship between these two markets, measured as the ratio of Brazil's Bovespa index to Argentina's Merval index. Using rescaled range analysis, we identify the presence of a...

Предметом исследования в статье является процесс демократизации в современном глобализирующемся мире. Глобализация теоретически изображается в виде...

We numerically investigate the electric potential distribution over a two-dimensional continuum percolation model between the electrodes. The model consists of overlapped conductive particles on the background with an infinitesimal conductivity. Using the finite difference method, we solve the...

The aggregation of polymer colloids is studied in processes induced at high ionic concentration. Cluster-size distributions are measured with a single-cluster light scattering instrument constructed by our team. A brief description of the instrument is given and its proper performance is...
