Análise bibliométrica de Gambling utilizando métricas da WoS e VOSviewer
Tinoco, Rui; Oliveira, Lúcia; Ribeiro, AndreiaEnquadramento: O Gambling é uma área de estudo complexa que implica diferentes olhares e perspetivas disciplinares. Diversos estudos bibliométricos encontraram uma preponderância na área da investigação da tomada de decisão, entre outras áreas. Pretende‑se contextualizar essa preponderância, ao mesmo tempo que se atualiza tendências de investigação na área. Métodos: Conduziu‑se uma análise bibliométrica usando ...
Global partnerships to local challenges : the actor's vision and the new educat...
Oliveira, Lúcia; Sangreman, Carlos; Faria, RaquelThe global partnerships for development are an important incentive to local growth as joint efforts are made to assist developing countries. We emphasize actions in the field of education, as they constitute a catalyst for local development, with a special focus on HE since empirical evidence shows that this level of education represents an important factor in local, national and global economic progress. It is...
Contributions of body fat, fat free mass and arm muscle area in athletic perfor...
Oliveira, Lúcia; Oliveira, Saulo; Guimarães, Fernando; Costa, ManoelThe aims of this study were: to verify the relationship (1) and dependency (2) between body fat (BF), fat free mass (FFM) and the arm muscle area (AMA) with athletic performance of wheelchair basketball players. Twenty-two subjects were evaluated according to the following order, in 24-hour intervals: a) anthropometric measurements and the Wingate anaerobic test (day 1); b) assessment of VO2peak and threshold (...
The health surveillance and decayed, missing and filled teeth index in children
Bica, Isabel; Oliveira, Lúcia; Montero, Javier; Costa, José; Estudantes 25º CLE, ESSV, IPVIntroduction Oral diseases are a major public health problem because they affect much of the population, particularly, children at early ages (DGS, 2008). Objectives Evaluate the dmft/DMFT index in children in pre-school and school age; To analyze the health of children (health surveillance and oral hygiene) and eating habits. Methods Quantitative, descriptive, exploratory and observational study in a non-proba...

Lipophilic phytochemicals from banana fruits of several Musa species
Vilela, Carla; Santos, Sónia A. O.; Villaverde, Juan J.; Oliveira, Lúcia; Nunes, Alberto; Cordeiro, Nereida; Freire, Carmen S. R.The chemical composition of the lipophilic extract of ripe pulp of banana fruit from several banana cultivars belonging to the Musa acuminata and Musa balbisiana species (namely 'Chinese Cavendish', 'Giant Cavendish', 'Dwarf Red', 'Grand Nain', 'Eilon', 'Gruesa', 'Silver', 'Ricasa', 'Williams' and 'Zelig') was studied by gas chromatography-mass spectrometry for the first time. The banana cultivars showed simila...
High valuable compounds from the unripe peel of several Musa species cultivated...
Villaverde, Juan José; Oliveira, Lúcia; Vilela, Carla; Domingues, Rosário M.; Freitas, Nélia; Cordeiro, Nereida; Freire, Carmen S. R.The lipophilic extractives of the unripe peel of ten banana cultivars belonging to the Musa acuminata and Musa balbisiana species (namely ‘Giant Cavendish’, ‘Chinese Cavendish’, ‘Grand Nain’, ‘Gruesa’, ‘Williams’, ‘Ricasa’, ‘Eilon’, ‘Zelig’, ‘Dwarf Red’ and ‘Silver’) were studied by gas chromatography–mass spectrometry. The extractives content were in the range of 2–3% with substantially higher values for ‘Silv...
The ripe pulp of Mangifera indica L.: a rich source of phytosterols and other l...
Vilela, Carla; Santos, Sónia A. O.; Oliveira, Lúcia; Camacho, João F.; Cordeiro, Nereida; Freire, Carmen S. R.; Silvestre, Armando J.D.The chemical composition of the lipophilic extracts of the ripe pulp of mangoes from twelve cultivars of Mangifera indica L. from Madeira Island was investigated by gas chromatography–mass spectrometry (GC–MS) for the first time. The ripe pulp of these mango cultivars showed analogous amounts of lipophilic extractives, as well as sim ilar qualitative chemical compositions. The predominant compounds were free an...
Novel bacterial cellulose-acrylic resin nanocomposites
Trovatti, Eliane; Oliveira, Lúcia; Freire, Carmen S.R.; Silvestre, Armando J.D.; Neto, Carlos Pascoal; Pinto, José J.C. Cruz; Gandini, AlessandroThe preparation and characterization of new nanocomposite films based on two acrylic emulsions, composed of random copolymers of butyl acrylate and methyl methacrylate, and bacterial cellulose is reported. The new composite materials were obtained through a simple and green approach by casting water-based suspensions of the acrylic emulsions and bacterial cellulose nanofibrils. The excellent compatibility betwe...
New biocomposites based on thermoplastic starch and bacterial cellulose
Martins, Ivo M. G.; Magina, Sandra P.; Oliveira, Lúcia; Freire, Carmen S. R.; Silvestre, Armando J. D.; Neto, Carlos Pascoal; Gandini, AlessandroBacterial cellulose, produced by Acetobacter Xylinum, was used as reinforcement in composite materials with a starch thermoplastic matrix. The composites were prepared in a single step with cornstarch by adding glycerol/water as the plasticizer and bacterial cellulose (1% and 5% w/w) as the reinforcing agent. Vegetable cellulose was also tested as reinforcement for comparison purposes. These materials were char...
