QoS in 4G scenarios using NSIS protocol

This paper presents quality of service mechanisms, based on the NSIS (Next Steps In Signaling) protocol. For that, it was implemented a testbed with NSIS running through IPv6. The network’s QoS was measured by the number of drops, for each flow (either QoS or Best Effort traffic), occurred in routers. The first experiment shows the captured packets during a node association and request for QoS, namely a G...

In this work, the volatile chromatographic profiles of roasted Arabica coffees, previously analyzed for their sensorial attributes, were explored by principal component analysis. The volatile extraction technique used was the solid phase microextraction. The correlation optimized warping algorithm was used to align the gas chromatographic profiles. Fifty four compounds were found to be related to the sensorial ...

Estudo comparativo entre bupivacaína (S75-R25) e ropivacaína em bloqueio peridu...

JUSTIFICATIVA E OBJETIVOS: A anestesia peridural é utilizada para alívio da dor no trabalho de parto e está associada a baixos índices de complicações. Estudos com enantiômeros levógiros dos anestésicos locais demonstraram maior segurança em função da menor cardiotoxicidade. Este estudo teve o objetivo de avaliar a latência e a duração da analgesia e as repercussões maternas e fetais com o emprego da bupivacaín...
