Advancing Permafrost Monitoring With Autonomous Electrical Resistivity Tomograp...
Farzamian, M.; Blanchy, G.; McLachlan, P.; Vieira, Gonçalo; Esteves, M.; de Pablo, M. A.; Triantifilis, J.; Lippmann, E.; Hauck, C.Abstract Permafrost is a widespread phenomenon in the cold regions of the globe and is under-represented in global monitoring networks. This study presents a novel low-cost, low-power, and robust Autonomous Electrical Resistivity Tomography (A-ERT) monitoring system and open-source processing tools for permafrost monitoring. The processing workflow incorporates diagnostic and filtering tools and utilizes open-s...
An assessment of the weight of the experimental component in physics and chemis...
Figueiredo, M.; Esteves, M.; Neves, J.; Vicente, H.; Chaves, HumbertoExperimentalworkplaysacentralroleinPhysicsandChemistryteach- ing. However, the use of experimental work depends on the perception that teacher has about the gains in terms of the students’ motivation and learning. Thus, this study aims to evaluate the weight of the experimental component in the chemistry teaching focusing on four topics, i.e., material resources, teaching methodologies, learning achievements, a...
Investigating collapse structures in oceanic islands using magnetotelluric surv...
Martínez-Moreno, F.J.; Monteiro Santos, Fernando Acácio; Madeira, José; Pous, J.; Bernardo, I.; Soares, A.; Esteves, M.; Adão, F.; Ribeiro, J.One of the most remarkable natural events on Earth are the large lateral flank collapses of oceanic volcanoes, involving volumes of rock exceeding tens of km3. These collapses are relatively frequent in recent geological times as supported by evidence found in the geomorphology of volcanic island edifices and associated debris flows deposited on the proximal ocean floor. The Island of Fogo in the Cape Verde arc...
Water prospection in volcanic islands by Time Domain Electromagnetic (TDEM) sur...
Martínez-Moreno, F.J.; Monteiro Santos, Fernando Acácio; Madeira, J.; Bernardo, I.; Soares, A.; Esteves, M.; Adão, F.Water demand in islands, focused in agriculture, domestic use and tourism, is usually supplied by groundwater. Thus the information about groundwater distribution is an important issue in islands water resources management. Time Domain Electromagnetic (TDEM) provides underground resistivity distribution at greater depths and is of easier application than other methods. In this study TDEM technique was used for ...

Fluorescence Study of Dehydroabietic Acid-Based Bipolar Arylamine-Quinoxalines
Burrows, H.; Fonseca, S.; Gigante, B.; Esteves, M.; Guerreiro, A.The absorption and fluorescence spectra, lifetimes and quantum yields of a series of triarylaminequinoxaline bipolar compounds, with and without the bulky dehydroabietic acid group, have been studied in toluene solution. This bulky group is introduced to improve solubility and thermal properties of these systems. It is shown that this does not affect their spectral or photophysical behavior. The compounds show ...
A comunicação com a criança na punção venosa: percepção do enfermeiro
Teixeira, A.; Braga, A.; Esteves, M.RESUMO A comunicação é uma competência essencial no desempenho dos Enfermeiros, sendo factor determinante na relação de ajuda e um indicador na avaliação da qualidade dos cuidados prestados, nomeadamente em Pediatria. Objectivos: Conhecer a percepção dos enfermeiros acerca da comunicação com a criança dos 7 aos 11 anos na punção venosa e identificar sugestões para melhorar a comunicação com esta durante esse pr...
