CHARACTERIZATION OF HYPERTENSION IN A INTERNAL MEDICINE WARD
Duarte, Rodrigo; Flores, Raquel; Pereira, JoãoIntroduction: Arterial hypertension is a serious disease, affecting more than 60% of individuals over 60 years-old. It is associated with the development of cardiac disease, terminal renal failure and cerebral disease, with increased risk of cognitive decline and dementia. The World Health Organization and the European Society of Cardiology forewarn about a low therapeutic compliance and impact, thus being cont...
DESEMPENHO ZOOTÉCNICO DE SUÍNOS DE RAÇA ALENTEJANA SUBMETIDOS A PROTOCOLOS DE I...
Charneca, Rui; Lopes, Jordana; Ramos, Catarina; Martins, José Manuel; Payan-Carreira, Rita; Laranjo, Marta; Braz, Maria; Branco, SandraOs suínos machos de raça Alentejana são normalmente abatidos a idade e peso elevado e, por isso, sujeitos a orquiectomia para evitar os odores e sabores “a macho”, consequência da deposição de androstenona e escatol na gordura, o que acontece a partir da puberdade. Este tipo de orquiectomia eletiva tem sido objeto de diversas ações a nível da União Europeia tendo em vista a sua proibição, atendendo aos seus efe...
EFEITOS DA IMUNOCASTRAÇÃO DE MACHOS SUÍNOS DE RAÇA ALENTEJANA NO DESENVOLVIMENT...
Charneca, Rui; Martins, José Manuel; Hernández-García, Francisco; Izquierdo, Mercedes; Lopes, Jordana; Ramos, Catarina; Braz, Maria; Carreira, EmanuelPara estudar e validar métodos alternativos à castração cirúrgica em machos suínos de Raça Alentejana, foi realizado um estudo no âmbito do projeto “SUMO: Sustentabilidade do Montado” sobre a eficácia e efeitos da imunocastração (IMC). Monitorizaram-se 30 machos entre os 5 e os 14 meses, divididos em 3 grupos experimentais de 10 animais cada: Grupo C – controlo com animais submetidos a orquiectomia; Grupo IMCP ...
Long-Range RFID Indoor Positioning System for an Autonomous Wheelchair
Pereira, JoãoA new Radio-Frequency Identification (RFID) indoor positioning system (IPS) has been developed to operate in environments where the Global Positioning System (GPS) is unavailable. Traditional RFID tracking systems, such as anti-theft systems in clothing stores, typically work within close proximity to exit doors. This paper presents a novel RFID IPS capable of locating and tracking passive RFID tags over a larg...
Wage Cyclicality and Labor Market Institutions
Pereira, João; Ramos, Raul; Pedro, MartinsDo labor institutions influence how wages respond to the business cycle? Such responsiveness can then shape several economic outcomes, including unemployment. In this paper, we examine the role of two key labor market institutions—collective bargaining and temporary contracts—upon wage cyclicality. Our evidence is drawn from rich, 2002–2020 matched data from Portugal. We find that workers not covered by collect...
The reproductive ecology of Loligo squids (Cephalopoda: Myopsida) in Lusitanian...
Laptikhovsky, Vladimir; Moreno, Ana; Oesterwind, Daniel; Perales-Raya, C.; Pierce, Graham; Robin, J.-P.; Sobrino, Ignacio; Valls, M.; Villanueva, R.Analysis of the temporal and spatial distribution of 686 records of egg masses and egg mass groups from (i) recreational divers and posted in the various public media, (ii) scientific survey data collected during research programs and (iii) publications in peer-reviewed literature plus published and unpublished information on the seasonality of the occurrence of mature females, demonstrated that the reproductio...
Desvendar o potencial da Ciência Aberta: perspetivas da engenharia biomédica e ...
Sayal, Alexandre; Direito, Bruno; Travassos, Carolina; Pereira, JoãoA Ciência Aberta potencia a partilha do conhecimento entre a comunidade científica e a sociedade. Mais do que acesso aberto de dados e publicações, é a construção de pontes no processo científico, promovendo transparência, acessibilidade e colaboração na investigação científica. A interoperabilidade (um dos princípios FAIR) é um aspeto chave. Neste sentido, a adoção de standards de dados e metadados é fundament...
Neurofeedback training of executive function in autism spectrum disorder: disti...
Pereira, Daniela Jardim; Morais, Sofia; Sayal, Alexandre; Pereira, João; Meneses, Sofia; Areias, Graça; Direito, Bruno; Macedo, AntónioBackground Deficits in executive function (EF) are consistently reported in autism spectrum disorders (ASD). Tailored cognitive training tools, such as neurofeedback, focused on executive function enhancement might have a significant impact on the daily life functioning of individuals with ASD. We report the first real-time fMRI neurofeedback (rt-fMRI NF) study targeting the left dorsolateral prefrontal cortex ...
Edge-aided V2X collision avoidance with platoons: Towards a hybrid evaluation t...
Pereira, João; Kurunathan, Harrison; Filho, Ênio; Santos, Pedro M.Infrastructure-brokered collision avoidance is an Intelligent Transportation Systems (ITS) application built on top of Vehicle-to-Everything (V2X) links. An edge-hosted ITS service receives information from road-side sensors (or CAM messages in V2X-enabled vehicles) and detects impending collisions where vehicles cannot sense or contact each other directly. If so happens, it issues a warning message through net...
Virtual immersive training model with mixed reality for prosthesis application ...
Alves, Diogo; Gomes, Paulo Veloso; Magalhães, Renato; Pereira, João; Vilaça, Adélio; Marques, António; Machado Veloso Gomes, Paulo SérgioTraining medical professionals in Orthopedics faces several technical challenges. The equipment required for practical, hands-on training is often restricted to operating rooms. This constraint presents a significant issue, as developing the necessary skills to perform surgeries requires substantial practice time. This work developed a virtual training model using mixed reality, using a QR code to generate a vi...
