We present the theoretical framework to efficiently solve Jeans equations for multi-component axisymmetric stellar systems, focusing on scaling of all quantities entering them. The models may include an arbitrary number distributions, a dark matter halo, and central supermassive black hole; each distribution is implicitly described by two- or three-integral function, components can have differe...

The present research work, using different softeners against water and air permeability resistance. In this three concentration for each of silicone & Fatty acid have been synthesized. Air are discussed by changing the amount softener concentration. It was a great effort to figure out optimal level that would be breathable permeability. results show if is increased, woven fabric decreases, whic...

In this paper, we revisit the governing equations for linear magnetohydrodynamic (MHD) waves and instabilities existing within a magnetized, plane-parallel, self-gravitating slab. Our approach allows fully non-uniformly magnetized slabs, which deviate from isothermal conditions, such that well-known Alfv\'en slow continuous spectra enter description. We generalize modern MHD textbook treatments...
