	Dynamics of a bubble in variable pressure and temperature fields of a liquid Zima, Patrik ; Maršík, František A study of nucleation and growth of bubbles in a liquid by means of a method based on the nucleation pulse in a shock tube is proposed. The nucleation of bubbles in the shock tube is initiated by a sudden depressurization due to the expansion of the liquid. It is assumed that the nucleation is homogeneous and the nucleation rate and the growth of bubbles can be evaluated using the light scattering method. Description of the experimental setup and analytical solution of the expansion of water in a shock tube are given. The theory of radial dynamics of a spherical vapor/gas bubble in a liquid is then employed in the form of the Rayleigh-Plesset equation and some aspects of inertially controlled bubble growth are discussed. The governing equation and conditions for mass transfer across the bubble boundary due to diffusion of the contaminant gas are given. Úplný záznam
	Friction and lubrication in artificial joints Vocel, Jan ; Musil, Jan ; Šída, V. The changes in function of artificial joint could be caused also by inconvenietn lubricant. At present time besides ionic fluids also some water soluble polymers and their derivatives have been investigated. Friction measurements using a technical frictional machine showed low coeficient of friction with negligible wear. Úplný záznam
	The influence of the membrane transport on the heart mechanical activity Převorovská, Světlana ; Maršík, František The mechanical activity of the heart muscle is the response of the electrochemical processes at the myocardial cells level. The influence of the sodium, potassium and calcium ions transport through the myocyte cells membrane and the generation of the myocardial action potential on heart mechanical activity has been simulated by the numerical model.
