Saúde positiva em casa
Galvão, Ana Maria; Gomes, Maria José; Pinheiro, MarcoO projeto SPC – Saúde Positiva em Casa, é caraterizado por dois pilares: 1. Formação de cuidadores e assistentes pessoais; 2. Prestação de cuidados de saúde no domicílio a doentes crónicos e aos respetivos cuidadores informais, resultando na promoção da capacitação/literacia em cuidados de saúde e consequentemente na qualidade da saúde e bem-estar geral. Com o SPC pretende-se replicar e adaptar em Portugal o mo...
Sensitivity and specificity of different measures of adiposity to distinguish b...
Lopes, Luís; Santos, Rute; Moreira, C.; Pereira, Beatriz; Lopes, Vitor P.This study aimed to determine the ability of different measures of adiposity to discriminate between low/high motor coordination and to evaluate the relationship between different measures of adiposity and motor coordination. METHODS: This study included 596 elementary school children aged 9 to 12 years (218 females - 47.1%). Weight, height, and waist circumference were objectively measured by standardized prot...
Resistência a temperaturas elevadas de vigas parcialmente embebidas com betão
Gonçalves, CarlosEste trabalho foi desenvolvido para o preenchimento dos requisitos da obtenção do grau de mestre em Engenharia da Construção. A motivação para este trabalho está relacionada com a ausência do conhecimento sobre o comportamento a temperaturas elevadas de elementos de viga parcialmente embebidos com betão (PEB) e a necessidade de apresentação de formulações simplificadas para a análise de vigas PEB à flexão. Fora...
Providing tools to improve forest management in the northeastern region of Port...
Pérez-Rodríguez, Fernando; Nunes, Luís; Sil, Ângelo Filipe; Azevedo, JoãoThe sustainable use of natural resources, such as forest resources, require sound management practices, from both environmental and socioeconomic perspectives, supported by reliable and accurate models and tools developed at proper scales. In forestry, however, tools that use regionally adjusted growth and yield models may not always be available, in particular in mountain areas where local environmental condit...
From the reservoir to the city: a contribution to promote the sustainable use o...
Geraldes, Ana Maria; Silva, Flora; Morais, Tiago; Vale, Patrícia; Zavattieri, Carmem; Albuquerque, AntónioThe management of reservoirs, classified as heavily modified water bodies by the Water Framework Directive (Directive 2000/60 of 23 October, amended in 2019), aims to achieve their good or very good ecological potential. However, the intense water use by human populations causes accentuated water level fluctuations, contributing to the disruption of the reservoirs´ littoral zone and to an accentuated increase i...
Effect of corrugation angle on the thermal behaviour of power-law fluids during...
Fernandes, Carla S.; Dias, Ricardo P.; Nóbrega, João M.; Maia, João M.In this study, CFD calculations were made in order to analyze the thermal behaviour of a power-law fluid in the channels of plate heat exchangers with corrugation angles of 30º and 60º. For the observed laminar flow, the numerical results show the absence of a typical local temperature profile in the 3D channel. Local Nusselt numbers and transversal variations of viscosity along the plate heat exchangers were s...
Territorial resources and sustainable innovation in tourism accommodation: a po...
Fernandes, Catarina; Pinheiro, EduardoThe tourism industry is under increasing pressure to address its negative externalities, mitigate resource depletion, and adapt to changing consumer expectations. In this context, sustainable innovation has emerged as a critical strategy for achieving sustainable growth and competitive differentiation, encompassing the development and implementation of new products, processes, and organizational practices that ...
Nanodispersions of beta-carotene: effects on antioxidant enzymes and cytotoxic ...
Rocha, Felipe; Sugahara, Letícia Yumi; Leimann, Fernanda Vitória; Oliveira, Sara Marchesan de; Brum, Evelyne da Silva; Calhelha, Ricardo C.Beta-carotene is a carotenoid precursor of vitamin A, known for its biological activities. Due to its high hydrophobicity, nanonization processes, i.e. the transformation into nanoparticles, can improve its water affinity, and therefore the activity in aqueous systems. The objective of this study was to produce beta-carotene nanoparticles by the solid dispersion method and to evaluate their effects on the activ...
Análise cromatográfica de um extrato fenólico de funcho utilizado no desenvolvi...
Caleja, Cristina; Barros, Lillian; Antonio, Amilcar L.; Ćirić, Ana; Soković, Marina; Oliveira, Beatriz; Santos-Buelga, CelestinoAtualmente, existe uma grande procura de alimentos com ingredientes naturais em substituição de aditivos sintéticos que têm sido associados, em determinadas circunstâncias, a alguns efeitos tóxicos [1]. Neste trabalho, preparou-se um extrato aquoso por decocção de Foeniculum vulgare Mill. (funcho) que, após caracterização por HPLC-DAD-ESI/MS, revelou a presença de cinco flavonoides (sendo o maioritário o querce...
Kinetic insights on wet peroxide oxidation of caffeine using EDTA-functionalize...
Díaz de Tuesta, Jose Luis; Almeida, Flávio V.M.; Oliveira, Jéssica; Praça, Paulo; Guerreiro, Mário C.; Gomes, Helder; Oliveira, JessícaNowadays, sorted organic fraction of municipal solid waste is typically treated by anaerobic digestion processes, resulting therein a solid stream, further processed to obtain compost, whose production is higher than the existing demand as fertilizer. The current work proposes an alternative strategy for the recovering of compost through the production of low-cost catalysts by calcination (1073 K) and sulfuric ...
