Abstract The surface of Tecoflex SG-80A Polyurethane (PU) films was modified by grafting polyethylene glycol (PEG) chains at three different molar amounts (0.05, 0.10, and 0.15 mmol). The resulting substrata were characterized by FTIR-ATR, TGA, AFM,

Performance and feeding behaviour traits in growing pigs could be affected by social interaction effects when animals are raised in group. So, properly knowing the genetic correlations between direct and social interaction effects among performance a

La rinotraqueitis infecciosa bovina (IBR) es una enfermedad ampliamente difundida en el mundo con gran repercusión socio-económica en las ganaderías bovinas. El objetivo del presente estudio fue determinar la prevalencia de IBR en 100 hatos del de

Despite the significance of the Galapagos archipelago, the richness of diverse groups such as braconid wasps remains poorly studied. Seven species of chelonine Braconidae are recorded for the Galapagos islands for the first time: Chelonus buscki Vier

Very little is known about the sand wasp, Bicyrtes variegatus, in the Galápagos archipelago. In this study, we compiled information from surveys, museum collections and the literature to better understand its distribution and ecology. We found recor
