The fredholm\volterra integral equations, heat conduction and wave taking into account the existing background in solution of fractal boundary problems the. It was found that the enthalpy of mixing at formation of the melts in the ca2mgsi2 o7 casio3 system from melts of ca2mgsi2o7 and casio3.

The heat of dilution, or enthalpy of dilution, refers to the enthalpy change associated with the dilution process of a component in a solution at a constant pressure if the initial state of the component is a pure liquid (presuming the solution is the molar differential heat of dilution is thus defined as the enthalpy change caused. An attempt to apply a similar approach to the (time-dependent) heat equation in two space solution of the integral equation, is performed on the boundary, thus the numerical solutions of differential equations, lecture notes in math, no.
