The article is devoted to the study of administrative corruption in the model of combining general and private interests, taking into account the costs of controlling agents. As the subject of research, we considered mathematical models of a combination of general and private interests of a hierarchical structure such as "Principal-Agent" and "Supervisor-Agent". The administrative control mechanism was investigated for the case where the principal sets a lower constraint.

The paper is devoted to the generalized analysis of the research on the influence of the electric field and organic gelling additives on the properties of foam concrete. It is shown that the transmission of the electric field close to the resonance frequency oscillations of the particles in the binder or the introduction of slip mass gelling components lead to a significant increase in the physical and mechanical characteristics of the foam.
Keywords: foam, impact properties, field modifiers.
