In the present paper CFD simulation of theunshrouded axial turbine stage flow is carried out.Simulation aim is to analyse interaction mechanismbetween main flow and secondary vortices from hot gasleakage in blade tip clearance. Authors shows that tipclearance has a strong influence on secondary flowsstructure and intensity and also on stage efficiency.Computational results are compared with literatureexperimental data and emperical dependences.

Scanning of the plantar surface of the foot wascarried out consistently under compressive loads on eachfoot which were equal to 50% and 80% of the person’s bodyweight by means of the computerized plantography. Theheight of the longitudinal arch of the foot was measuredconcurrently. The obtained data of the elasticity of thehuman foot allow to characterize its amortisation function.The foot indicators (resilience coefficient, deformationcoefficient, Young’s modulus and Poisson's coefficient)characterize its amortisation function and ability to resist theaction of loadings.
