Zeolite modification for optimizing Fenton reaction in methylene blue dye degra...
Carvalho, Ana P.; Costa, José; Martins, Angela; Fonseca, António; Neves, Isabel C.; Nunes, NelsonTextile dyes often prove resistant to conventional wastewater treatment processes because of their complex molecular structures. Advanced oxidation methods, such as the Fenton reaction, have thus been recognized as a promising approach for environmental remediation by decomposing these pollutants. This work aimed to study the efficacy of modified zeolites as catalysts in the Fenton reaction for dye degradation,...
Descoberta de conhecimento em dados de mobilidade urbana: um exemplo de intelig...
Alves, Carlos; Mendes, Luís; Costa, José; Machado, José; Machado, RicardoNos Açores, tal como em Portugal Continental, as cidades inteligentes (as conhecidas smart-cities) continuam a enfrentar enormes desafios. Estes incluem a melhoria da infraestrutura tecnológica e da sua governança, que visa aumentar o envolvimento e a inclusão dos cidadãos e das instituições. Um dos principais desafios é a promoção da mobilidade dos cidadãos para melhorar a sua qualidade de vida e fomentar o se...
Data acquisition system for soil and air data monitoring using LoRA technology
Costa, José; Ferreira, João; Gomes, Pedro Miguel Pinto Reis; Pereira, Vitor Emanuel de Matos Loureiro da SilvaFerreira, Ana Cristina, e outros (2023) - International conference on technology management and operations. - Lisboa : Universidade Lusíada Editora. - ISBN 978-898-640-273-0.; This work explores the application of LoRA (Long Range) technology, which allows for the development of low-cost IoT systems. It consists of developing an IoT system for acquiring information about weather conditions (peripheral towers fo...
Validation of a Simplified Numerical Model for Predicting Solid–Liquid Phase Ch...
Rosa, Nuno; Soares, Nelson; Costa, José; Lopes, António GameiroThis paper presents a numerical model for simulating melting and solidification driven by natural convection, and validates it against a previous experiment. The experiment involved filling a rectangular aluminum enclosure with RT28HC Phase Change Material (PCM) to 95% of its capacity. To investigate the thermal behavior of the PCM during phase change, the enclosure underwent independent heating and cooling pro...
Alpha 1 - anti-trypsin deficiency - a rare case of hepatic cirrhosis in an adult
Silva, Eugénia; Marcelino, Paulo; Elvas, Assunção; Pereira, Lurdes; Costa, José; Coutinho de Miranda, AntónioThe authors present a rare clinical case report of liver cirrhosis in an adult patient with alphal are: PiSS, PiZZ, PiSZ and PiMZ. The patient presented the phenotype PiMF. Recent data supports a new perspective of this disease: the incorrect folding of the protein leads to its accumulation in the rough endoplasmic reticulum of the hepatocyte and consequently damages it. ; Os AA. apresentam um caso de cir...

Design procedures for sustainable structural concretes using wastes and industr...
Neves, Ana; Almeida, João; Cruz, Fábio Quintas; Miranda, Tiago F. S.; Cunha, Vitor M. C. F.; Rodrigues, Mafalda; Costa, José; Pereira, E. N. B.The protection of the environment must be a priority in our society, and the construction sector can contribute significantly to this goal. Construction, being one of the industrial sectors that is more demanding in terms of raw materials, must reinforce its effort to implement, in a more profound and systematic way, the paradigm of the circular economy. In this sense, in recent years several studies have been ...
Dermatomyositis and Crohn's disease – Case report
Neves, Ana; Mendonça, Inês; Marques, José; Costa, José; Almeida, JorgeImmune‐mediated diseases tend to overlap in ways that are not completely understood. When a presentation is not entirely explained by a former condition, other hypotheses should arise. Additionally, the activity of 2 overlapping immune‐mediated conditions is not always associated. We present an unusual association between Crohn's disease and dermatomyositis in a 28‐year‐old man. The patient presented with a 2‐m...
Gastric metastasis from lung adenocarcinoma: an uncommon presentation
Neves, Ana; Mendonça, Inês; Marques, José Alberto da Cunha; Costa, José; Almeida, Jorge S.Gastric metastasis is an infrequent occurrence, especially when derived from lung adenocarcinomas. They can grossly resemble advanced gastric cancer and require comprehensive evaluations of the patients and their symptoms.Here, we present the case of a 71-year-old patient admitted to our hospital due to intense, cramping abdominal pain. He had been previously diagnosed with a right lower lobe adenocarcinoma of ...
Confirmatory Evaluation of the Modified Medical Research Council Questionnaire ...
Ribeiro, Soraia; Cardoso, Carlos Seiça; Valério, Margarida; Machado, João; Costa, José; Rodrigues, Cidália; Rebelo-Marques, AlexandreThe Modified British Medical Research Council Questionnaire is considered an adequate and simple measure of breathlessness in chronic obstructive pulmonary disease. It is widely used in clinical practice in Portugal, but it still lacks confirmatory evaluation for the Portuguese setting. The aim of this study was to perform a cultural adaptation and validation of the Modified British Medical Research Council Que...
