The report discusses the theory of transport processes to include solids dielectrics, metals, and ferrites in the case when normal collisions between quasiparticles have maximum probability. It is shown that although normal collisions do not lead themselves to a finite resistance, they can strongly affect the resistance produced by other scattering processes, so that the kinetic coefficients and their dependence on the temperature and other parameters are appreciably altered. The character of the influence of normal collisions depends strongly both on the type of the quasiparticles electrons, phonons, spin waves and on the nature of the mechanism leading to the loss of quasimomentum Umklapp, collisions with impurity atoms, with sample boundaries, etc..
