TRIDENT is developing a new architecture and technological solutions for long-term deep-sea monitoring. In December 2024, TRIDENT had a set of prototypes ready and undergoing further testing, prototypes that will help ensure these new technological approaches. These will provide a new tactic to deep-sea EIA since they intend to support the long-term deployment of an autonomous, dynamic, robotic set of assets, r...
O consumo de bebidas alcoólicas entre estudantes do ensino superior é um tema de grande relevância, pois essa fase da vida é marcada por mudanças significativas e novas experiências. Objetivos: Avaliar o risco de dependência de álcool dos estudantes do Instituto Politécnico de Bragança. Metodologia: Estudo de caráter quantitativo, observacional e transversal, baseado numa amostra não-probabilística por conveniê...
Fishing for deep-sea species occurs on continental slopes, ridges, and seamounts. Fishing operations using fishing gears that contact the bottom (e.g., trawls and bottom longlines) may have significant impacts on Vulnerable Marine Ecosystems (VMEs). VMEs refer to marine ecosystems with a population or community of sensitive taxa or habitats that are likely to experience substantial alteration from short-term to...
Expanded cork polymer composites (eCPC) using a PLA matrix and expandable microspheres (EMS) were developed and characterized. A blowing agent was introduced to evaluate its effect on cork structure in eCPC injected pieces. A chemical and thermal characterization was conducted using Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC) and Fourier Transform Infrared-Attenuated Total Reflecti...
Fish otolith age calibration and exchanges are carried out periodically to improve the quality of age data used in age-based stock assessments. These calibrations use online tools for age reading and the statistical analysis are frequently done on Eltink 2000 spreadsheet. With the replacement of this software and Eltink limitations, statistical evaluation was performed using R code. This change has shown clear ...
In this work, the physicochemical characterization of five (Al2O3, In2O3, Mn3O4, SiO2 and SnO2) nanoparticles (NPs) was carried out. In addition, the evaluation of the possible toxic impacts of these NPs and the respective modes of action were performed using the yeast Saccharomyces cerevisiae. In general, in aqueous suspension, metal(loid) oxide (MOx) NPs displayed an overall negative charge and agglomerated; ...
Objetivo: Analisar os efeitos de um programa de reeducação funcional respiratória pré e pós-operatório na dor, frequência respiratória e saturação de oxigénio do cliente submetido a gastrectomia programada. Método: Estudo quase-experimental e longitudinal, sustentado num paradigma quantitativo, com uma amostra de 60 clientes distribuídos por dois grupos: 30 controlo e 30 intervenção. Resultados: Baixos níveis d...
The Laboratory of Sclerochronology and the age and growth studies of fishing resources A brief description of the growth studies developed by IPMA, I.P. is given in this report, with emphasis on the halieutic species currently studied both within the scope of the National Programme of Biological Sampling (under the EU/DG Fisheries’ Data Collection Framework (DCF)) as of other research projects and research line...
The present work aims to contribute for the elucidation of the role of oxidative stress in the toxicity associated with the exposure of Pichia kudriavzevii to multi-metals (Cd, Pb and Zn). Cells of the non-conventional yeast P. kudriavzevii exposed for 6 h to the action of multi-metals accumulated intracellular reactive oxygen species (ROS), evaluated through the oxidation of the probe 2',7'-dichlorodihydrofluo...
