Mind the (social and emotional competence) gap to support higher education stud...
Oliveira, S.; Maçarico, T.; Pacheco, R.; Janeiro, I.; Marques-Pinto, A.Today’s increasingly brittle, anxious, nonlinear, incomprehensible world of work calls for a socially and emotionally competent workforce. However, there is a clear gap in higher education settings regarding the assessment and promotion of students’ social and emotional competence (SEC). Our study aims to address the pressing need to evaluate and develop higher education students’ SEC by providing a tool to ass...
Star-like glycosaminoglycans with superior bioactivity assemble with proteins i...
Novoa-Carballal, R.; Carretero, A. C.; Pacheco, R.; Reis, R. L.; Pashkuleva, I.We show that glycosaminoglycans (GAGs) with high molecular weight can be grafted via their reducing end on hyper-branched synthetic cores by oxime condensation without the need of any previous functionalisation of the polysaccharide. The versatility of this reaction is demonstrated by the use of hyaluronan, chondroitin sulfate and heparin with up to 60 sugar units. The isothermal calorimetry analysis demonstrat...
Evaluation of Jerusalem artichoke as a sustainable energy crop to bioethanol: e...
Paixão, Susana M.; Alves, Luís; Pacheco, R.; Silva, Carla M.ABSTRACT: An alternative to the sugar/starch-based crops bioethanol is lignocellulosic biomass, but its utilization to biofuels is still not economically viable. In this context, an increasing interest has arising on the search for specific energy crops that do not require arable lands and are not water intensive, such as Jerusalem artichoke (JA). So, this work consisted on the cultivation of JA on those agricu...
Chemical and antioxidant profiles of acorn tissues from Quercus spp.: Potential...
Vinha, Ana F.; Costa, A.S.G.; Barreira, João C.M.; Pacheco, R.; Oliveira, BeatrizThe bioactivity of different organs and tissues of Quercus spp. (Fagaceae), an important group of evergreen or deciduous trees from temperate and tropical climatic areas, represents a good starting point for possible industrial applications. Nevertheless, Quercus fruits, generally known as acorns, are currently undervalued and underexploited. Accordingly, the proximate composition, fatty acids and tocopherols p...

Ferreira da Vinha, Ana; Costa, A.S.G.; Barreira, João C.M.; Pacheco, R.; Oliveira, M. Beatriz P.P.The bioactivity of different organs and tissues of Quercus spp. (Fagaceae), an important group of evergreen or deciduous trees from temperate and tropical climatic areas, represents a good starting point for possible industrial applications. Nevertheless, Quercus fruits, generally known as acorns, are currently undervalued and underexploited. Accordingly, the proximate composition, fatty acids and tocopherols p...
Issues to be considered on obtaining plant models for formal verification purposes
Pacheco, R.; Gonzalez, L.; Intriago, M.; Machado, José; Prisacaru, G.; Olaru, D.The development of dependable software for mechatronic systems can be a very complex and hard task. For facilitating the obtaining of dependable software for industrial controllers, some powerful software tools and analysis techniques can be used. Mainly, when using simulation and formal verification analysis techniques, it is necessary to develop plant models, in order to describe the plant behavior of those s...
The production of pigments & hydrogen through a Spirogyra sp. biorefinery
Pacheco, R.; Ferreira, Ana F.; Pinto, T.; Nobre, B. P.; Loureiro, David; Moura, Patrícia; Gouveia, Luisa; Silva, Carla M.This paper discusses the overall energy consumption and greenhouse gas emissions when extracting pigments and producing hydrogen from Spirogyra sp. microalga biomass. The energy evaluation from the biomass leftovers was also included in this work. The influence of the functional unit and different allocation criteria on the biorefinery assessments is also shown. The study consists of laboratory tests showing Sp...
Nutritional value and fatty acid profile from acorns (Quercus nigra): intending...
Pacheco, R.; Costa, A.S.G.; Pimentel, Filipa; Ferreira da Vinha, Ana; Oliveira, M.B.P.P.The development of rural areas depends on sustainability policies to promote agricultural and production systems, in order to increase those populations’ income. To attain this purpose, it is important to find new opportunities to valorize the available, but still underexploited, natural resources. Therefore, the aim of this study was to compare the nutritional profile of kernel, shell and the whole fruit of Qu...
Biodesulphurization of fossil fuels: energy, emissions and cost analysis
Alves, Luís; Paixão, Susana M.; Pacheco, R.; Ferreira, Ana F.; Silva, Carla M.In order to achieve stringent environmental and safety requirements, refineries are in search of “green” and cost-effective methods for crude oil desulphurization. Combined desulphurization technologies are being studied, including bioprocessing to upgrade fossil fuels. Using biodesulphurization (BDS), which is a biochemical process mediated by specific microorganisms, it is possible to desulphurize most of the...
