Mathematical model for calculating the force field of loads in the magnetic liquefied layer of electromechanical dispersants [PDF]

E3S Web of Conferences, 2021
The article presents an analysis of the dominant dispersants in the production of the agro-industrial complex. A qualitative transition to the level of a priori reduction of energy costs for the most energy-intensive in the process flow and process ...

Genetics of dispersal [PDF]

Biological Reviews, 2017
ABSTRACTDispersal is a process of central importance for the ecological and evolutionary dynamics of populations and communities, because of its diverse consequences for gene flow and demography. It is subject to evolutionary change, which begs the question, what is the genetic basis of this potentially complex trait?
