Fluid Dynamics of the São Jorge Channel, Azores Plateau First results of RV Met...

Young oceanic plateaus are important for fluid exchange between the lithosphere and the ocean. Increased heat fluxes can lead to a large-scale upwelling of fluids that play a role in global elemental cycles. In addition, variations in fluid chemistries can potentially influence the biomass and species compositions of microbial and benthic communities in sediments exposed to subsurface fluid flow. Yet, the prese...

Criatividade e dinâmicas culturais no espaço público. Com o foco em Évora

O texto toma como pressuposto o reconhecimento da importância das atividades culturais locais para vitalização dos espaços públicos urbanos e, decorrentemente, para participação formativa das/dos cidadãs/ãos. Ora estando Évora inscrita no programa internacional das Cidades Educadoras, desde 2001, e tendo recentemente recebido o título de Capital Europeia da Cultura (CEC) em 2027, pergunta-se quem está a promove...

Chemical Modification of Pachira aquatica Oil for Bio-Based Polyurethane Wood A...

The development of biomass-based adhesives has attracted interest as an alternative to petroleum-derived synthetic and potentially toxic adhesives. Pachira aquatica oil is a renewable raw material that can be incorporated into an MDI-based polyurethane system. In this study, the chemical composition and reactivity of P. aquatica oil were characterized using GC–MS, FTIR, and hydroxyl index measurements. The oil ...

ROBIN: Reference observatory of basins for international hydrological climate c...

Human-induced warming is modifying the water cycle. Adaptation to posed threats requires an understanding of hydrological responses to climate variability. Whilst these can be computationally modelled, observed streamflow data is essential for constraining models, and understanding and quantifying emerging trends in the water cycle. To date, the identification of such trends at the global scale has been hindere...

Mental health-promoting intervention models in university students: a systemati...

Background The transition to higher education represents a demanding adaptation process with several socioeconomic factors involved. Mental health problems among university students have been worsening since the beginning of the COVID-19 pandemic. Our objective is to create scientific evidence about the models of mental health-promoting interventions among higher education students applied in academic environme...

Optimising Legume Integration, Nitrogen Fertilisation, and Irrigation in Semi-A...

Monoculture systems depend on high nitrogen (N) fertilisation. Incorporating legumes into forage crops offers a sustainable alternative with agronomic and economic benefits. This study assesses the impact of legumes in fodder systems, evaluating yield, N use efficiency (NUE), and profitability while identifying the best cropping strategy under semi-arid conditions. The experiment, conducted at Herdade da Comend...

Response of Nearby Sensors to Variable Doses of Nitrogen Fertilization in Winte...

The sustainable intensification of forage production in Mediterranean climates requires technological solutions that optimize the use of agricultural inputs. This study aimed to evaluate the performance of proximal optical sensors in recommending and monitoring variable rate nitrogen fertilization in winter forage crops cultivated under Mediterranean conditions. A handheld multispectral active sensor (HMA), a m...

Marangatu: protagonismo das comunidades para o futuro da biodiversidade brasileira

The impact of the COVID-19 pandemic on Portuguese adults’ psychopathological sy...

BAC KGROUND: The impact of the pandemic on mental health has been demonstrated in several reports. The aim of the present study was to evaluate the impact of the COVID-19 pandemic on multiple dimensions of psychopathology in Portuguese adults. We compare a pandemic sample assessed during the second lockdown in Portugal with a prepandemic sample. METH ODS: Participants provided socio-demographic and clinical inf...
