How museums are changing their visitors’ experience with new formats and approa...
Lacet, Demetrius; van Zeller, Maria; Martins, Paulo; Morgado, LeonelThis study focuses on exploring new formats and innovative approaches to digital storytelling in museums, offering a critical analysis of existing formats and proposing new perspectives. Initially, current digital storytelling formats are examined, ranging from mobile applications and augmented reality to interactive and multimedia exhibitions. Next, new paradigms and strategies are discussed that aim to expand...
Body image concerns in people who underwent a total laryngectomy
Guimarães, Isabel; Torrejano, Gabriela; Aires, Raquel; Gonçalves, Filomena; Freitas, Susana Vaz; Correia, Paula; Romeiro, Cláudia; Silvestre, InêsAbstract: Background: Body image is a potential psychological burden after total laryngectomy (TL) with devastating effects on patients’ health-related quality of life (HRQOL) and communication. This study focused on TL patients to determine the prevalence of dissatisfied body image and whether they have poorer HRQOL and difficulty adjusting to their new voice than TL patients with satisfied body image. It also...
Psychotherapeutic playback theatre, well-being, and psychological distress: An ...
Gonzalez, A.-J.; Lima, Margarida Pedroso de; Preto, Luis; Martins, PauloABSTRACT: Psychotherapeutic Playback Theatre (PPT) is a new psychotherapeutic format inspired by Playback Theatre and several therapies. The research presented here aims to study the impact of PPT on the Well-being and Psychological Distress of participants in this expressive-based group psychotherapy. To achieve this, after training 30 psychotherapists and creating an implementation handbook for their use, the...
On the enhancement of material formability in hybrid wire arc additive manufact...
Pragana, João; Brito, Beatriz; Bragança, Ivo; Silva, Carlos; Martins, PauloThis paper is focused on improving material formability in hybrid wire-arc additive manufacturing comprising metal forming stages to produce small-to-medium batches of customized parts. The methodology involves fabricating wire arc additive manufactured AISI 316L stainless steel parts subjected to mechanical and thermal processing (MTP), followed by microhardness measurements, tensile testing with digital image...
Multi-planar injection lap riveting
Sapage, Miguel S. T.; Pragana, João P. M.; Sampaio, Rui F.V.; Bragança, Ivo; Silva, Carlos M. A.; Martins, PauloThis paper is focused on multi-planar hybrid busbars made from copper and aluminum for electric energy distribution systems. The objective is to provide an overview of its assembly by injection lap riveting in multidirectional tools and to compare the electrical performance of its joints against that of conventional (in-plane) busbars. The injected lap riveted joints require a dovetail ring hole and a countersu...
Joining by forming of bi-material collector coins with rotating elements
Rosado, Pedro M. S.; Sampaio, Rui F.V.; Pragana, João P. M.; Bragança, Ivo; Silva, Carlos; Martins, PauloThis paper presents a novel manufacturing process for producing innovative bi-material collector coins with free- rotating inner elements. The inner elements are fabricated using additive manufacturing, enabling the creation of coins with complex and intricate geometric details that would be unattainable using conventional wrought materials. The outer elements (rings) are metallic, and this study addresses the ...
A strain acceleration method to identify the onset of diffuse necking
Sampaio, Rui F. V.; Pragana, João; Bragança, Ivo; Silva, Carlos; Martins, PauloThis paper presents an innovative ‘strain acceleration method’ for determining the onset of diffuse necking in sheet forming tests using data obtained from digital image correlation (DIC). The method identifies the onset time of diffuse necking and provides the corresponding in-plane principal strain values by detecting a local extreme in the second derivative of the minor principal in-plane strain with respect...
Quando as Redes Sociais Digitais São Fontes Jornalísticas — Uma Abordagem a Cód...
Martins, PauloA influência dos média sociais no campo do jornalismo, hoje incontornável, manifesta-se em várias vertentes, criando desafios que não podem ser ignorados pelos profissionais. Enquanto fontes, estão a ser cada vez mais utilizados, contribuindo para a emergência de novas dinâmicas de produção noticiosa, em particular na cobertura de acontecimentos em continuidade, nos quais impera a velocidade de transmissão e o ...
Functional rhinoseptoplasty: clinical decision protocol
Arede Antunes, Miguel; Fernandes, Rita; Arede, Carolina; Martins, Paulo; Luís, LeonelIntroduction: Functional Rhinoseptoplasty (F-RSP) is a complex procedure with increased morbidity and substantially longer operative time compared to conventional septoplasty. On this regard, the clinical decision concerning this procedure should be thoughtful and objective. Both the nasal septum and the internal and external nasal valves play crucial roles in nasal airflow, emphasizing the importance of direct...
Mechanical and thermal processing of wire-arc additively deposited stainless steel
Silva, Carlos; Pragana, João; Bragança, Ivo; Martins, PauloMechanical and thermal processing of wire-arc additively deposited stainless steel is investigated with the purpose of improving its microstructure, surface morphology, formability, and stress response. Microscopy helps identifying the processing conditions that permit full recrystallization of the as-built columnar microstructure. Combination with strain loading paths, topography and fractography in tensile te...
