Remote Nodes topologies for hybrid WDM-ring TDM-tree passive optical networks

In this paper is presented a WDM-ring TDM-tree passive optical network able to provide more than 1024 users spread over 100km with a symmetrical bandwidth of 100Mbps. A set of optically fed passive remote nodes are also presented able to provide increased efficiency and resili90ency. ; In this paper is presented a WDM-ring TDM-tree passive optical network able to provide more than 1024 users spread over 100km ...

Crosstalk de Raman em Serviços de Vídeo sobre Redes Óticas Passivas de Próxima ...

; Neste trabalho é avaliado o impacto causado pelo efeito de Raman sobre um sistema de vídeo overlay (1550nm) na evolução rumo à próxima geração de redes de acesso óticas passivas (NG-PON2). Em primeiro lugar é estudado o impacto causado por um sinal modulado e de seguida é analisado um sistema multi- comprimento DWDM.

Os Factores Genéticos na Perda Gestacional

Pregnancy loss is the most common obstetric complication. Multiple factors have been associated with recurrent or sporadic pregnancy loss, and genetic factors, particularly at earlier gestational ages, are the most important ones. The proportion of miscarriages due to chromosomal factors decreases with increasing gestational age. The most common chromosomal abnormalities in early losses are autosomal trisomies,...

Novel methodology based on biomimetic superhydrophobic substrates to immobilize...

Cell-based therapies for regenerative medicine have been characterized by the low retention and integration of injected cells into host structures. Cell immobilization in hydrogels for target cell delivery has been developed to circumvent this issue. In this work mesenchymal stem cells isolated from Wistar rats bone marrow (rMSCs) were immobilized in alginate beads fabricated using an innovative approach involv...

Multilayered polymeric particle production using superhydrophobic surfaces meth...

Encapsulating technologies that render spherical particles containing cells or relevant moleculeshave been developed to be used in fields such as tissue engineering, pharmaceutics, cosmetics, agriculture, as also in other bio-related applications, namely biosensors and bioreactors. The multiple bioactive agents release, with an important role in tissue regeneration, constitutes an important strategy in tissue e...

Novel methodology based on biomimetic superhydrophobic substrates to immobilize...

The low retention/integration of injected cells by host structures represents an important challenge in cell based therapies for regenerative medicine purposes. Cell immobilization in hydrogels for target cell delivery has been developed to circumvent this issue. However, the existing immobilization methodologies sometimes have several steps under wet conditions and present some drawbacks, including poor encaps...
