Nonlinear interaction of capillary waves for the first azimuthal modes an elliptical jet in electric cross-section field is examined by product two independent small parameters. The itself arises due to ellipticity section perpendicular jet. Three azimuth participate interaction: either even or odd ones. When compared with a radial electrostatic field, stability uniform reduced. It turned out t...

The article is devoted to the thermal calculation of a flat plate solar collector. In this case, boundary conditions are third kind. solution found in transition an elliptical coordinate system. author has obtained analytical for distribution temperature field collector with cross-section at zero ambient partial adiabatic isolation form functional series using hypergeometric functions.

The article calculates the temperature field in an elliptical body with internal heat dissipation. In this case, boundary conditions are of third kind. solution is located at transition to elliptic coordinate system. author has obtained analytical for distribution a cross-section infinite length zero ambient partial adiabatic isolation form functional series using hypergeometric functions.

We study the influence of shape plasma container on dynamics Reversed Field Pinch (RFP). The geometries we consider are periodic cylinders with elliptical and circular-shaped cross-sections. Numerical simulations fully nonlinear visco-resistive magnetohydrodynamics carried out to illustrate how affected by shaping. It is shown that independent shape, quantity $\beta$, comparing hydrodynamic pre...

The article deals with the distribution of temperature field in an elliptical body without internal heat sources. In this case, boundary conditions are third kind. solution is found when moving to elliptic coordinate system. author has obtained analytical for a cross section infinite length at given ambient partial adiabatic isolation form functional series using hypergeometric functions.

Mesoporous silica films templated by pluronic P123 were prepared using spin and dip coating. The ordered cylindrical structure within the films deforms due to shrinkage during calcination. Grazing-incidence small-angle X-ray scattering (GISAXS) measurements reveal that both the unit cell and the cross section of the pores decrease in size, mainly normal to the surface of the substrate, leading ...

Laser-induced space-selective crystallization of glass enabling the growth continuous crystal-in-glass architectures consisting non-centrosymmetric phases with functional properties is promising, including single-crystal waveguides for development integrated optical circuits. In this study, femtosecond laser direct writing crystalline lines inside lead germanate composition close to Pb5Ge3O11 h...
