An analytical dynamic model is presented for a spacecraft with multiple large flexible structures.Based on the partial differential equations (PDEs) of the motion of the solar panel and deployable arm, the governing equations of the main-body and deployable antenna and the boundary conditions at each end point are used to obtain the frequency and m
Parrots play a crucial role in the ecosystem by performing various roles, such as consuming the reproductive structures of plants and dispersing plant seeds.However, most are threatened because of habitat loss and commercial trade.Amazon parrots are one of the most traded and illegally traded parrots.Therefore, monitoring their wild populations and
Abstract Background Superparamagnetic iron oxide (SPIO) nanoparticles have been widely used in several biomedical engineering in vivo.Although Tiktok various surface modifications have been made to these non-biodegradable nanoparticles to make them more biocompatible, their toxic potential still remains a major concern.Method In this study, we newl
