It is shown that during diffusional growth of the intermediate phase between substances A and B for cylindrical and spherical samples, the total diffusion flux relative to the center, −S(r)D̃∂c/∂r, where S is the area of the interface, varies by a small amount in the radial direction, despite the concentration dependence of the interdiffusion coefficient D̃(c). In this context we propose a constant-flux method which allows the kinetics of the diffusional phase growth in cylindrical and spherical ...

The purpose of the article is to analyze and assess the budgetary VAT refund to national agricultural producers and develop specific proposals for its improvement, taking into account the provision of a close relationship between tax and customs legislation in agriculture. Conceptual approaches to the essence of budgetary VAT refunds have been systematized. An algorithm for the declared amount of budgetary VAT refunds has been developed. The conditions for exercising the exporter's rights to VAT ...
