Mathematical and computer modeling of gantry crane load-beam system oscillation
Sustainable Development of Mountain Territories, 2023 Introduction. Gantry grappling cranes are the main equipment for cargo transportation in the technological processes of mining and enrichment of rocks. During the operation of the crane, undesirable effects such as the rocking of the payload occur, which

Natal dispersal of Whooping Cranes in the reintroduced Eastern Migratory Population
Ecology and Evolution, 2021 Natal dispersal is a key demographic process for evaluating the population rate of change, especially for long‐lived, highly mobile species. This process is largely unknown for reintroduced populations of endangered avian species.
