Insights into the in-situ degradation and fragmentation of macroplastics in a low-order riverine system Open
Inland riverine systems are major conduits of microplastics (MPs) to coastal environments. Plastic materials that pass through riverine systems are subjected to various degradation processes that facilitate their fragmentation into MPs. Lo…

El impacto del buffer en la calidad de servicio Open
The response in data flows transmission in real time is analyzed, for access network scenarios, in which said flows converge on an outgoing link, competing to achieve a certain level of quality of service. The concurrence of these types of…
