A lattice Boltzmann scheme simulating the dynamics of shell models of turbulence is developed. The influence of high order kinetic modes (ghosts) on the dissipative properties of turbulence dynamics is studied. It is analytically found that when ghost fields relax on the same time scale as the hydrodynamic ones, their major effect is a net enhancement of the fluid viscosity. The bare fluid visc...

The problem of spectra formation in hydrodynamic approach to A+A collisions is discussed. It is analyzed in terms of the two different objects: distribution and emission functions. We show that though the process of particle liberation, described by the emission function, is, usually, continuous in time, the observable spectra can be also expressed by means of the Landau/Cooper-Frye prescriptio...

the seeds of lepidium sativum (garden cress) were selected as a new source of hydrocolloid and some of its fundamental physico-chemical properties such as intrinsic viscosity and functional group were determined. ftir analysis showed that this polymer was composed of carbohydrate with functional carboxyl and hydroxyl groups. intrinsic viscosity was determined to be 1.33 ml/mg in water. the hydr...

On the basis of the current knowledge of the structure and dimensions of myosin and its parts, we analyze available data on hydrodynamic properties (translational diffusion, rotational diffusion, and intrinsic viscosity) for comparison with values calculated for models with varying geometry. Special attention is paid to detecting flexibility effects in those properties. After obtaining a plausi...

The behaviour of extended particles with exclusion interaction on a one-dimensional lattice is investigated. The basic model is called ℓ-ASEP as a generalization of the asymmetric exclusion process (ASEP) to particles of arbitrary length ℓ. Stationary and dynamical properties of the ℓ-ASEP with periodic boundary conditions are derived in the hydrodynamic limit from microscopic properties of the...

The heteronuclear NMR relaxation of globular proteins depends on the anisotropic rotational diffusion tensor. Using our previous developments for prediction of hydrodynamic properties of arbitrarily shaped particles, by means of bead models, we have constructed a computational procedure to calculate the rotational diffusion tensor and other properties of proteins from their detailed, atomic-lev...
