The paper presents the solution of the problem of simulation of the effect of radiant heat fluxes from infrared sources (IRS) on the surface of spacecraft and their modules during complex tests in a vacuum chamber (VC) Health 600/300.We suggest using empirical dependences as a solution to the problem of promptly obtaining the results of calculating
Abstract We carried out uniaxial compression tests on brittle red sandstone with different heights.The test results show that the uniaxial compressive strength of rock sample increases first and then tends to be stable with the increase of the size, which is approximately stable between 75 and 81 MPa.Both elastic energy and dissipated energy increa
The problems of the concession development are Gear Shift Products considered, which is one of the forms of public-private partnership during developing difficult for access mineral deposits.Data on the historical experience of this form of management in the world and in Russia, including in mineral resources use, are given.The specifics of the imp
We perform scanning gate experiments on ballistic constrictions in the presence of small perpendicular magnetic fields.The constrictions form the entrance and exit of a circular gate-defined ballistic stadium.Close Health to constrictions we observe sets of regular fringes creating a checker board pattern.Inside the stadium conductance fluctuations
