Thermal performance of a hybrid BIPV-PCM: modeling, design and experimental inv...

Aelenei, Laura; Pereira, R.; Gonçalves, Helder; Athienitis, Andreas

In this paper, a BIPV-PCM installed in an office building façade is investigated to approach the practical application of PV-PCM. Based on an updated mathematical model, theoretical simulation has been conducted for BIPV-PCM in this case. Furthermore, field testing for this case has also been performed to validate the model, and then the simulated and experimental results are compared and found in considerably ...

Omental whirl associated with bilateral inguinal hernia: a case report

Silva, E; Carvalho, AF; Rocha, D; Rodrigues, AM; Pereira, R; Rodrigues, AJ; Leão, P

Torsion of the omentum is a rare cause of abdominal pain. It is clinically similar to common causes of acute surgical abdomen and is often diagnosed during surgery. Inguinal hernia is a common condition but not frequently related with torsion of the omentum. CASE PRESENTATION: A 40-year-old Caucasian man came to our emergency department with abdominal pain of the left quadrant and abdominal distension for 2 da...


PV system with maximum power point tracking: modeling, simulation and experimen...

Pereira, R.; Melício, R.; Mendes, V. M. F.; Joyce, António

This paper focuses on the five parameters modeling, consisting on a current controlled generator, single-diode, a shunt and series resistances. Also, a simulation, identification of the parameters for a photovoltaic system and the maximum power point tracking based on VP„g„g is presented. The identification of parameters and the performance of the equivalent circuit model for a solar module simulation are valid...

Impact of composition and morphology on the optical properties of Si-NC/P3HT th...

Rodrigues, F. D.; Cunha, Mara; Hilliou, L.; Rino, L.; Correia, M. R.; Busani, T.; Bernardo, Gabriel; Wiggers, H.; Filonovich, Sergey; Pereira, R. N.

Blends of Si nanocrystals (Si-NCs) and organic semiconductors are promising materials for new optical and electronic devices processed from solutions. Here, we study how the optical properties of composite films containing Si-NCs and the organic semiconductor poly(3-hexylthiophene) (P3HT) are influenced by the composition and morphology resulting from different solution-processing parameters and different solve...

Platelet iysate maintains chondrogenic potential and promotes cartilage regener...

Pereira, R. C.; Scaranari, M.; Strada, P.; Reis, R. L.; Cancedda, Ranieri; Gentili, Chiara

cartilage. We report the biological effect of the platelet lysate (PL), a PRP derivative, on primary human articular chondrocytes (HAC) cultured under both physiological and inflammatory condition. Added to the culture medium, PL induced a strong mitogenic response in the chondrocytes. The in vitro expanded cell population maintained a chondrogenic re-­‐differentiation potential as revealed by micromass culture...


Effects of moderate electric fields (MEF) on denaturation of whey proteins solu...

Pereira, R. N.; Teixeira, J. A.; Vicente, A. A.

Electric fields application during thermal processing are now receiving increased attention due to uniform heating of liquids and extremely rapid heating rates, which presumably enables higher temperatures to be applied without inducing excessive denaturation of the constituent proteins [1]. The aim of this work was to evaluate the effects of moderate electric fields (MEF) on denaturation kinetics and thermodyn...


A multibiomarker approach in the clam Ruditapes decussatus to assess the impact...

Cravo, Alexandra; Pereira, C.; Gomes, T.; Cardoso, C.; Serafim, A.; Almeida, Cheila Pereira; Rocha, T.; Lopes, B.; Company, R.; Medeiros, A.

The Ria Formosa lagoon is an ecosystem whose water quality reflects the anthropogenic influence upon the surrounding areas. In this lagoon, the clam Ruditapes decussatus has a great economical importance and has been widely used as a biomonitor. A multibiomarker approach (d-aminolevulinic acid dehy- dratase, metallothionein, lipid peroxidation, acetylcholinesterase, alkali-labile phosphates, DNA damage) was appli...
