Tunning pectinase activity under the effects of electric fields in the enhanced...
Queirós, Mariana; Pereira, Guilherme; Leite, Ana Catarina Carvalho Oliveira; Leal, Rita; Rodrigues, Rui Miguel Martins; Teixeira, J. A.Introduction: Pectinolytic enzymes are of great importance for the clarification process of “Vinho Verde” wine must, contributing to the reduction of haze development. During the last decade, a growing body of knowledge has been established about the effects of electric fields on the activation of important food enzymes. However, the influence of electrical parameters on catalytic activity is enzyme-dependent a...
Activity Based Simulation - A Modeling Tool for New Teaching/Learning Strategies
Pereira, Guilherme; Vieira, António; Ricardo, Machado; B., Fernandes; L., Dias; José A., OliveiraTeaching and learning Discrete Event Simulation (DES) at universities within the context of undergraduate studies in industrial and engineering management is not thoroughly covered in the literature. In fact, most strategies tend to solely address commercial tools, resulting on too much focus on syntax, semantics and getting used to the interface of a particular tool, rather than on simulation fundamental conce...
On the Integration of Industrial Data and Analysis with Simulation in a Company...
Mesquita, C.; Vieira, António; Dias, L.; Pereira, Guilherme; Oliveira, José A.Nowadays, companies are constantly seeking to develop tools to increase productivity, production flexibility and the quality of their products, or to reduce costs, delays and their exposure to risks. In fact, such improvements can be achieved in the scope of product as well as of process improvement. In industrial contexts, often, such improvements can be achieved by implementing tools to access the intended in...
Challenges to represent and manage transport and material handling systems in m...
Gonçalves, Micael; Martins, Paulo Jorge de Figueiredo; Pereira, GuilhermeTransport and Material Handling Systems (TMHS) are characterized by behaviors, properties, rules and restrictions which makes their representation challenging. The literature about representing and/or modeling TMHS is not extensive, despite its acknowledged importance. Several challenges to represent TMHS are identified and discussed in this paper, such as TMHS with several devices, restrictions, shapes of netw...
Assigning products in a Vertical Lift Module supermarket to supply production l...
Vieira, António Amaro Costa; Dias, Luis S.; Pereira, Guilherme; Oliveira, José A.This paper presents the development of a mathematical model for product assignment in a Vertical Lift Module (VLM), which are increasingly em-ployed in the industrial sector due to their advanced technology and efficient parts-to-picker process. Mathematical modelling plays a crucial role in address-ing the complexity of these problems and providing intelligent and innovative solutions. Despite being a tactical...
MAMMALS IN PORTUGAL: A data set of terrestrial, volant, and marine mammal occur...
Grilo, Clara; Afonso, Beatriz C.; Afonso, Filipe; Alexandre, Marta; Aliácar, Sara; Almeida, Ana; Alonso, Ivan Prego; Álvares, Francisco; Alves, PauloMammals are threatened worldwide, with 26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mam mals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems func tionality and resilience, and theref...
Activity based simulation - A modeling tool for new teaching-learning strategies

Evaluating the make-to-order performance of production control systems in a re-...
Araújo, Ana; Pires, Margarida; Pereira, Maria; Ribeiro, Sónia; Varela, M.L.R.; Henriques, Marcelo Filipe Nunes; Dias, Luis S.; Pereira, GuilhermeIn the current Industry 4.0 era, simulation, along with approaches for dealing with production activity control, is considered of the utmost importance, for instance, in cyber-physical production systems, but also in any other traditional manufacturing environment. In this context, there are varying kinds of production activity control mechanisms that can be explored, and a wide range of contributions are alrea...
Tunning pectinase activity under electric field effects towards enhanced clarif...
Pereira, Guilherme; Queirós, Mariana; Carvalho, Gonçalo; Pereira, Ricardo Nuno CorreiaVinho Verde (translates as green wine) is one of the most important and leading DOC (Denomination of Controlled Origin) product in Portugal and known worldwide by its unique aromatic profile. Pectinolytic enzymes are of the great importance in the clarification process of Vinho Verde wine must, contributing to reduce the possibility of haze formation. During last decade a growing body of knowledge have been est...
Even generalist and resilient species are affected by anthropic disturbance: ev...
Rosalino, L. M.; Teixeira, Daniela; Camarinha, Cláudia; Pereira, Guilherme; Magalhães, Ana; Castro, Guilherme; Lima, Cátia; Fonseca, CarlosHumans have negatively impacted most ecosystems on Earth, altering how species use habitats and resources available to them, but also their circadian rhythms. Among many factors affecting animal activity patterns, conversion of native habitat into production forests and hunting are critical, and their impacts may be exacerbated by seasonal weather conditions. Both these factors are issues in Mediterranean Europ...
