Distribution of 3G signals over fiber
Daniel L. Beato; António J. V. Amador; N. Martins; R. Nogueira; A. Teixeira; P. André; M. LimaIn this work we study the feasibility of UMTS (3G) transmission over Passive Optical Networks (P.O.N.). In order to achieve such objective, it was developed a simulator, so that we could correctly model the system and conclude about its impairments. The simulation results obtained validate this kind of transmission and highlight the associated limitations. ; Neste trabalho é estudada a viabilidade da tr...
Optimização eficiente do ganho espectral de amplificadores de Raman com bombage...
B. Neto; S. Stevan Jr.; R. Nogueira; A. L. J. Teixeira; M. J. N. Lima; P. S. AndréWe report the use of the Genetic Algorithm (GA) in the optimization of a distributed Raman amplifier spectralgain. The used methodology is based on the direct integrationof Raman propagation equations making use of the transfermatrix method, which ensue into a considerable reduction ofthe computation time. Pointing out an on/off Raman gain of10 dB, we develop a technique based in a combination of theGA with the...

The impact of GGH -401C>T polymorphism on cisplatin-based chemoradiotherapy res...
Silva, IH; Nogueira-Silva, C; Figueiredo, T; Lombo, L; Faustino, I; Catarino, R; Nogueira, A; Nogueira, D; Medeiros, RAIMS: Cervical cancer is the third most frequent cancer in women worldwide, mostly treated with cisplatin-based chemoradiotherapy. Since it is known that folate metabolism might interfere with cisplatin effectiveness, we intended to study the influence of the Gamma Glutamyl Hydrolase -401C>T polymorphism in treatment response in cervical cancer. METHODS: We retrospectively reviewed the clinical data of 167 pat...

The marine algal (seaweed) flora of the Azores: 4, further additions
León-Cisneros, Karla; Tittley, Ian; Terra, Marlene R.; Nogueira, Eunice M.; Neto, Ana I.Eight records of seaweeds are reported new to the mid-Atlantic Azores archipelago. Coelothrix irregularis and Lejolisia sp. fall within their overall distributional range. Sebdenia rodrigueziana and Syringoderma floridana have their north-western limit of distribution there. The islands represent the western limit of occurrence for Antithamnionella boergesenii, Aphanocladia stichidiosa, Sebdenia dichotoma, and ...
Thermal skin reference values in healthy late pregnancy
Simões, R; Vardasca, R; Nogueira-Silva, CDigital thermal imaging has been employed in medicine for over 50 years. However, its use has been focused on vascular, musculoskeletal and neurological conditions, while other potential applications, such as obstetrics, have been much less explored. This paper presents a study conducted during 2011 at the Hospital of Braga on a group of healthy pregnant women in the last third of gestation. The analysis focu...
