Molecular and hydraulic responses of grapevine to water status and phenology un...
Damásio, M.; Pinto, C.; Salguero, J.; Alarcón, M. V.; Deus, J.; David, T. S.; Silvestre, J.; Carvalho, L. C.; Zarrouk, OlfaUnderstanding seasonal interactions among hydraulic, chemical and molecular signalling under water deficit is crucial for improving vineyard irrigation strategies under climate change and increasing water scarcity. We aimed to test how irrigation strategies and phenology affect the hydraulic adjustment mechanisms of eight fieldgrown grapevine varieties under different long-term irrigation regimes: Full-irrigate...
Llife cycle assessment of a fabric based on conventional cotton versus recycled...
Pinto, C.; Abreu, Maria JoséThrough the Life Cycle Assessment (LCA), the study compares the environment impacts of two fabrics with different compositions: a 100% conventional cotton fabric versus a fabric with 60% pre-consumer recycled cotton and 40% conventional cotton fibers. The main purpose is to prove how much environmental impacts can be reduced using pre-consumer recycled cotton.
Red mud valorization in stoneware pastes: technical and environmental assessment
Vilarinho, I. S.; Dias, A. C.; Carneiro, J.; Pinto, C.; Labrincha, J. A.; Seabra, M. P.Red mud (RM), resulting from alumina production by Bayer process, is classified as hazardous waste and is, nowadays, one of the most abundant industrial waste worldwide. Currently, over 4 billion tons are stored in ponds/dried mounds and is of utmost importance to tackle this problem. This work aims to recycle RM as colouring agent in stoneware products. For this purpose, several proportions of RM (0–10 wt%) we...
Effect of high pressure on the properties of chocolate fillings during long-ter...
Panda, A.; Coelho, Patrícia; Silva, J.; Lampreia, Célia; Pinto, C.; Amaral, R.; Saraiva, J.; Dias, João; Alvarenga, Nuno; Santos, Maria TeresaThe aim of this study was to evaluate the impact of high-pressure processing (HPP) on the long-term storage of chocolate fillings at room temperature, compared with conventional storage at lower temperatures. Dark chocolate fillings were treated at different pressure levels, holding times and stored at 20 °C for 12 months. Unprocessed batches were stored at 4 °C and at -12 °C. Moisture, water activity (aw), pH,...
Insights on the use of wind speed vertical extrapolation methods
Pintor, A.; Pinto, C.; Mendonça, J.; Pilão, Rosa Maria; Pinto, P.The present work aims to study the influence of using different methods for wind speed extrapolation in energy production calculations. A dataset of 21 meteorological masts from several landscape characteristics and locations, with at least one year of 10-minute wind speed/direction data, was used as the basis for calculations. Both the power law through estimation of wind shear coefficients, and the logarithmi...
The relationship between quality management and innovation
Pinto, C.; Romero, FernandoPurpose: The purpose of this study is to understand the relationship between quality management and innovation, since although quality and innovation issues are dealt with extensively, there is still little information on this relationship. Project/Methodology/Approach: For this study, an exploratory bibliographic research was conducted in order to extract the most important ideas from the literature. Findings:...

Enterprise risk management in Portugal
Pinto, C.; Azevedo, G.; Oliveira, J.The present chapter tries to assess the state of art of Enterprise Risk Management (ERM) among Portuguese non-financial companies regarding two main aspects: the ERM background in Portugal and the level of disclosure of ERM practices by non-financial listed companies. Since the analysis of disclosures is useful to understand the level of evolution and adoption of ERM framework we tried to assess the ERM practic...
Prevalence of shigatoxigenic Escherichia coli in bovine cattle: a survey in the...
Ballem, Andressa; Gonçalves, Soraia; Ferreira, A.I.; Fernandes, Conceição; Saavedra, Maria José; Pinto, C.; Oliveira, H.; Almeida, GonçaloShiga toxin-producing Escherichia coli (STEC) strains are food-borne pathogens that can be transmitted to humans through many different routes, but mainly through consumption of contaminated foods. STEC strains are characterized by the production of Shiga toxins (Stx) that are encoded by two genes stx1 and/or stx2. Each toxin can be subdivided into subtypes and, currently, there are three known subtypes for stx...
