We have constructed a physico-mathematical model of photodynamic therapy of skin tumors taking into account the photochemical reactions and the features of the radiation propagation, the heat and mass transfer, and the mass transfer of oxygen in the

The problem of diffusion transfer of oxygen from an individual capillary into the surrounding skin with regard for the inhomogeneity of the blood composition in the vessel (plasma and erythrocytes) has been solved. The approximate dependence of the a

The influence of the change in the temperature and the acidity of blood on its hemorheological properties has been analyzed. It is shown that, at temperatures lower than 45°C, the temperature dependence of the apparent viscosity of blood at a rate o

The motion of an individual deformable erythrocyte in a capillary whose diameter is smaller than the particle diameter has been considered. The problem formulation is based on the Lighthill-Fitzgerald model. The erythrocyte drag at a given pressure d

A new model of approximation of the blood‐flow curve with five parameters independent of the hematocrit and the rate of shear is proposed. On the basis of the statistical analysis, we have shown the reliability of differences of the mean values of

A model of the dependence of the relative viscosity of blood and suspensions of erythrocytes on their volume concentration is proposed. Both parameters of the model correlate differently with each other in three regions of erythrocyte concentrations

A mathematical model of blood flow in arterial vessels with account for the nonstationary character of the laminar flow and the time-varying pressure drop is considered. The viscosity of blood is assumed to obey a power law. The rheological propertie

The dissipation of a microwave field in an inhomogeneous plane layer covered by external semitransparent screens is investigated. It is shown that use of the screens makes it possible to control the dissipation process: to displace the nodes and anti
