Investigating the hydrothermal activity at Fogo volcano (Cape Verde) using geoc...
Candeias, Carla; Rocha, Fernando; Dumont, Stéphanie; Maineult, Alexis; Ramalho, Ricardo; Madeira, José; Antunes, JoãoABSTRACT: Characterizing hydrothermal systems at volcanoes is particularly important as they play a crucial role in controlling eruptive dynamics. On the long term, hydrothermal systems participate in the geochemical alteration of both rocks and soils, through hydrolysis, dissolution, mineral precipitation, and secondary mineralization contributing in the gradual destabilization of volcanic structures. Fogo vol...
Comparação de métodos de determinação do carbono orgânico em solos de Portugal
Couchinho, Filipa; Paz, Ana M.; Mano, Raquel; Moura, Maria J.; Antunes, João; Castanheira, Nádia; Gonçalves, Maria C.A matéria orgânica é fundamental para funções do solo como sejam a regulação dos ciclos de carbono, nutrientes e água ou a sua capacidade produtiva. A monitorização deste parâmetro, avaliado pelo teor de C orgânico (Corg), pode ser complexa, dada a sua lenta evolução no tempo e elevada variabilidade no espaço. Assim, é fundamental definir métodos confiáveis de quantificação do Corg no solo, permitindo uma monit...
Comparing approaches for evapotranspiration partitioning: single vs. dual crop ...
Antunes, João; Gonçalves, Maria Conceição; Castanheira, Nádia; Couchinho, Filipa; Paz, Ana MartaSoil evaporation and crop transpiration are fundamental processes in modelling water transport, which is crucial for irrigation planning and scheduling. This study compares two methods to determine these components of crop evapotranspiration: (i) the straightforward single crop coefficient method, and (ii) the dual crop coefficient method, which may be more suitable for daily irrigation scheduling. Experimental...
The positive and negative suicidal ideation inventory among portuguese adolesce...
Brás, Marta; Cunha, Ana Margarida; Antunes, João; Carmo, CláudiaSuicide worldwide is an issue that needs to be addressed, and adolescents are an at-risk group. Assessing suicidal ideation is central to tackling the issue of suicide. The Positive and Negative Suicidal Ideation inventory is a widely validated measure of suicidal ideation, and yet, very little is known about its invariance across various groups. The present study aimed to adapt and test the PANSI’s structure i...
Perfectionism and emotion regulation in the study of suicidal ideation in portu...
Brás, Marta; Antunes, João; Reis, Ana; Carmo, CláudiaSuicide is a serious public health problem worldwide, being the culmination of a process that normally begins with suicidal ideation. Therefore, it is important to assess suicidal ideation and know its risk factors. The association between perfectionism and suicidal ideation has been widely debated in the literature. However, knowledge about the role of emotion regulation in this relationship is scarce. The mai...

The psychometric properties of the positive and negative suicidal ideation scal...
Brás, Marta; Antunes, João; Carmo, CláudiaPreventing suicide has been a worldwide imperative for the last decade. Accurately assessing suicide risk is the first step towards prevention, and access to reliable tools that measure risk factors is essential to achieve this goal. The Positive And Negative Suicidal Ideation (PANSI) scale is a validated brief suicidal ideation scale that could prove useful to this goal due to its ability to measure both suici...
Análise da influência do tempo de repouso na condutividade elétrica da pasta sa...
Antunes, João; Paz, Ana Marta; Castanheira, Nádia; Gonçalves, Maria Conceição; Cortez, NunoA condutividade elétrica do extrato pasta saturada do solo (ECe) é amplamente usada como medida de referência para a salinidade do solo, pois permite a comparação da salinidade entre solos independentemente de seu teor de água em condições de campo. Ao mesmo tempo, a ECe é mais comparável com condutividade da solução do solo (ECsw) do que a dos extratos de outras razões solo-água (1:1, 1:2 ou 1:5). A pasta satu...
A HOME-BASED PREHABILITATION PROGRAM, DELIVERED THROUGH AN INTERNET-BASED PLATF...
Moreira-Gonçalves, Daniel; do Vale Fernandes, Antero; Daher Mota, Clara; Antunes, João; Canappele, Carina; Martins, Pedro; Santos, Fátima; Cabral, SóniaIntroduction: Prehabilitation is a multimodal strategy implemented in the preoperative period, aiming to increase preoperative functional reserve, leading to better postoperative functional recovery and reduced incidence of complications. The majority of the prehabiliation programs are developed under supervision in an outpatient clinic, which might be an obstacle for those patients with geographical and/or tra...
Ein Cloze Test zur Sprachstandserhebung portugiesischer L2 Lerner des Deutschen
Setas, Maria Clara Silva; Sousa, Inês; Antunes, João; Flores, CristinaThis study aims to test the feasibility of a research tool, a Cloze Test, developed to assess the proficiency of German as a second language (L2) in native speakers of European Portuguese (EP). The Cloze Test is a fill-in-the-gap test used as a tool to measure the participants’ proficiency of linguistic competence, taking into account their lexical, morphosyntactic and discursive knowledge of varying complexity...
