Removal of drugs for aqueous matrices by adsorption with activated carbon
Exposto, Bruno; Cruz, Marisa; Brito, Paulo; Queiroz, Ana; Ribeiro, António E.Micropollutants are substances which are found in very low concentration (μg/L or ng/L) in water bodies [1]. However, these compounds are only partially filtered by effluent treatment plants (ETEs), which results in water and soil contamination and can become both an environmental and health hazard [2]. One such micropollutant is naproxen, a non-steroidal anti-inflammatory drug (NSAID), prescribed worldwide to ...
(Dys)Prosody in Parkinson’s disease: effects of medication and disease progress...
Frota, Sónia; Cruz, Marisa; Cardoso, Rita; Guimarães, Isabel; Ferreira, Joaquim; Pinto, Serge; Vigário, MarinaAbstract: The phonology of prosody has received little attention in studies of motor speech disorders. The present study investigates the phonology of intonation (nuclear contours) and speech chunking (prosodic phrasing) in Parkinson’s Disease (PD), as a function of medication intake and progression of the disease. Following methods of the prosodic and intonational phonology frameworks, we examined the ability ...

Frota, Sónia; Cruz, Marisa; Cardoso, Rita; Guimarães, Isabel; Ferreira, Joaquim J; Pinto, Serge; Vigario, MarinaThe phonology of prosody has received little attention in studies of motor speech disorders. The present study investigates the phonology of intonation (nuclear contours) and speech chunking (prosodic phrasing) in Parkinson’s disease (PD) as a function of medication intake and duration of the disease. Following methods of the prosodic and intonational phonology frameworks, we examined the ability of 30 PD patie...
The rhythm of interlanguage in the production of European Portuguese by Chinese...
Zhou, Chao; Cruz, Marisa; Frota, SóniaThe present research examines the rhythmic properties of European Portuguese spoken by native speakers of Mandarin Chinese. Based on the rhythm metrics and corpora used in previous studies focused on the comparison across different languages and varieties (Ramus, Nespor & Mehler, 1999; Frota & Vigário, 2001), we aimed at determining the rhythmic properties of the interlanguage and discussing the factors...
Glide insertion to break a hiatus across words in European Portuguese: the role...
Oliveira, Pedro; Cruz, Marisa; Paulino, Nuno; Vigário, MarinaGlide insertion to break hiatus has long been reported in the literature to occur in the Northern and Central varieties of Portuguese but this has not been systematically investigated before. From a larger corpus of speech material collected in several locations in the North and Center of Portugal, we selected for analysis a sample coming from six locations in the Northwest of Portugal and one location in the C...
Building a prosodic profile of European Portuguese varieties: the challenge of ...
Cruz, Marisa; Oliveira, Pedro; Palma, Pedro; Neto, Bruno; Frota, SóniaIn the present paper we explore a methodology to map prosodic variation in Portuguese, namely intonation and rhythm, which goes beyond the traditional approaches used to represent segmental, lexical or syntactic variation. To find the most adequate mapping method for intonation and rhythm, we tested spatial interaction models for the representation of nuclear contours, and spatial interpolation methods for rhyt...
O ritmo da interlíngua na produção do Português Europeu por falantes chineses
Zhou, Chao; Cruz, Marisa; Frota, SóniaThe present research examines the rhythmic properties of European Portuguese spoken by native speakers of Mandarin Chinese. Based on the rhythm metrics and corpora used in previous studies focused on the comparison across different languages and varieties (Ramus, Nespor & Mehler, 1999; Frota & Vigário, 2001), we aimed at determining the rhythmic properties of the interlanguage and discussing the factors that ma...
The role of intonation and visual cues in the perception of sentence types: Evi...
Cruz, Marisa; Swerts, Marc; Frota, SóniaIn this paper, we explore the role of intonation and visual cues in the perception of statements and questions in two varieties of European Portuguese—the standard (SEP) and the insular variety of Azores, Ponta Delgada (PtD)—previously shown to convey sentence type contrasts by different uses of intonational means and/or facial gestures, namely eyebrow movements. Forty native speakers (20 from each variety) wer...
Basic research in phonology, resources and applications: the case of frequency
Vigário, Marina; Martins, Fernando; Cruz, Marisa; Paulino, Nuno; Frota, SóniaÉ crescente a valorização da conversão do conhecimento fundamental desenvolvido pelos cientistas em produtos concretos, socialmente relevantes. No Laboratório de Fonética da Universidade de Lisboa tem-se trabalhado nos últimos anos tanto em domínios de investigação fundamental, como de investigação aplicada. Neste artigo é feita uma revisão dos principais recursos recentemente disponibilizados à comunidade por ...
Dysarthria in individuals with Parkinson’s disease: a protocol for a binational...
Pinto, Serge; Cardoso, Rita; Sadat, Jasmin; Guimarães, Isabel; Mercier, Céline; Santos, Helena; Atkinson-Clement, Cyril; Carvalho, Joana; Welby, PaulineIntroduction: Individuals with Parkinson’s disease (PD) have to deal with several aspects of voice and speech decline and thus alteration of communication ability during the course of the disease. Among these communication impairments, 3 major challenges include: (1) dysarthria, consisting of orofacial motor dysfunction and dysprosody, which is linked to the neurodegenerative processes; (2) effects of the pharm...
