Non-essential elements and their role in sustainable agriculture
Silva, Marta Nunes da; Machado, Joana; Osorio, Jazmin; Duarte, Rafael; Santos, Carla S.Agricultural systems are constantly under environmental pressure, and the continuous rise of the global population requires an increasingly intensification of agronomical productivity. To meet the current global food demand, particularly in depleted ecosystems under adverse climate conditions, the development of novel agronomical practices, which ensure crop productivity while safeguarding minimal impact to the...
Point cloud quality evaluation: Towards a definition for test conditions
Cruz, Luís; Dumic, Emil; Alexiou, Evangelos; Prazeres, João; Duarte, Rafael; Pereira, Manuela; Pinheiro, Antonio M. G.; Ebrahimi, TouradjRecently stakeholders in the area of multimedia representation and transmission have been looking at plenoptic technologies to improve immersive experience. Among these technologies, point clouds denote a volumetric information representation format with important applications in the entertainment, automotive and geographical mapping industries. There is some consensus that state-of-the-art solutions for effici...
Transformação estrutural no estado sólido de polímeros de coordenação de duas e...
Duarte, RafaelConselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq; Cobalt, nickel, copper and zinc acetate salts were reacted with the 1,4-α, α'- xylenediylabis(phenylphosphinate) (XBPP) ligand and two-dimensional CoII and ZnII coordination polymers were reacted with temperature control: by heating at reflux [Co (XBPP)]-aP (1-aP, triclinic) and [Zn(XBPP)]-aP (3-aP, triclinic); hydrothermal reactio...
Análise das ligações de hidrogênio em sais complexos e polímeros de coordenação...
Duarte, RafaelConselho Nacional de Desenvolvimento Científico e Tecnológico; In this work six aqua complexes of the transition metals Fe2+, Co2+, Ni2+, Cu2+, Zn2+ and Cd2+ containing the dithionate ion were synthesized and characterized through metathesis reactions in aqueous solution between BaS2O6·2H2O and the sulfate of the metal. Single crystals suitable for X-ray diffraction were obtained from the filtrates of the react...

Segmentation and fishery characteristics of the mixed-species multi-gear portug...
Duarte, Rafael; Azevedo, Manuela; Afonso-Dias, ManuelFleet segmentation and knowledge of fishing fleet dynamics are essential to move from single species to fishery/fleet-based advice. The coastal mixed-species multi-gear Portuguese fleet comprises medium-sized (> 12m) vessels, using a diversity of passive gears, and is economically important. For hake (under a recovery plan) and monkfish (overexploited), it contributes > 50% to their total annuel landings. Comme...
