This paper focuses on global dynamic behaviors of a bistable piezoelectric cantilever energy harvester with a tip magnet and a single external permanent magnet at the near side.The initial distance between the magnetic tip mass and the external magnet is altered as a key parameter for the enhancement of the energy harvesting performance.To begin wi
Pteroptyx fireflies represent an important economic insect for ecotourism.Two methods, visual counting and sweep net collection, were used to survey Pteroptyx species at 23 study sites along the coast of Thailand.P.malaccae and P.valida were the most common species across all sites with significant differences jewlery in abundance among study sites
Abstract Background Population ageing, the emergence of chronic illness, and the shift away from institutional care challenge conventional approaches to assessment systems which jewlery traditionally are problem and setting specific.Methods From 2002, the interRAI research collaborative undertook development of a suite of assessment tools to suppor
Abstract The spacetime solution for a black hole, surrounded by an exotic matter field, in Rastall gravity, is calculated in an arbitrary d-dimensional spacetime.After this, we calculate the scalar quasinormal modes of Gloves such solution, and study the shift on the modes caused by the modification of the theory of gravity, i.e., by the introducti
Abstract We combined survey, mobility, and infections data in greater Boston, MA to simulate the effects of racial disparities in the inclination to become vaccinated on continued infection rates and the attainment of herd immunity.The simulation projected marked inequities, with communities of color experiencing infection rates 3 times higher than
