Monitorização atmosférica dos níveis de NO₂ usando a técnica de amostragem passiva
Pinheiro, Claver Giovanni Silveira; Margalho, Élida Melo; Alcantara, Amanda; Júnior, Orlando Sousa Lima; Rocha Segundo, Iran Gomes daA qualidade do ar em áreas urbanas é um problema global que afeta a saúde pública e o meio ambiente e é muito afetada pelo trafego de veículos automóveis. Este estudo avalia a eficácia da amostragem passiva para medir a concentração de dióxido de nitrogênio (NO2) na cidade de Guimarães da região do Minho no noroeste de Portugal. Utilizando filtros de celulose impregnados com uma solução absorvedora, as amostras...
Circularity micro-indicators for plastic packaging and their relation to circul...
Matos, Joana; Martins, Carla I.; Simões, RicardoPlastic packaging, in the form of films, brought several advantages to the commercialization of products given its lightness and durability. It provided better ergonomics, ease of transport, increased shelf life, and easy handling and use. Despite that, plastic packaging is facing enormous sustainability concerns associated with the traditional practice of linear economy, combined with commonplace irresponsible...
Perfil de competências do enfermeiro numa unidade de transplantação cardíaca
Simões, RicardoIntrodução: A atual evolução tecnológica possibilita novas abordagens de cuidado à pessoa com patologia cardíaca, sendo a área da transplantação cardíaca um desses vetores. Tornase assim necessário que os enfermeiros com aEvidade profissional no âmbito da transplantação cardíaca (APTC), possuam um perfil de competências que lhes permita prestar cuidados de enfermagem à pessoa submeEda a transplante cardíaco. Ob...
Practical application of circularity micro-indicators to automotive plastic par...
Matos, Joana; Santos, Sara; Simões, Carla L.; Martins, Carla I.; Simões, RicardoThe increasing amount of plastics in new vehicles, and the consequent growth of plastics in the automotive shredder residue, makes it imperative and urgent to improve reuse and/or recovery of plastics at the vehicle’s end-of-life. Circularity micro-indicators can identify improvement guidelines and monitor the transition to a more circular economic model; however, the complexity, variety of scope and approach, ...
Tea tree oil: properties and the therapeutic approach to acne—a review
Nascimento, Tânia; Gomes, Diana; Simões, Ricardo; Miguel, MariaAcne vulgaris is an inflammatory dermatological pathology that affects mostly young people. However, it can also appear in adulthood, mainly in women. It has a high psychosocial impact, not only at the time of active lesions but also due to the consequences of lesions such as scarring and hyperpigmentation. Several factors are involved in the physiopathology of acne and the constant search for active ingredient...
Current and future opportunities for 3D printing in modern board games
Simões, RicardoAdditive manufacturing (3D printing) is a set of disruptive technologies where parts are no longer produced by removing material until the desired form is achieved, but rather build the intended product layer by layer. With significant benefits in the efficient use of resources, optimizing performance, and allowing individual customization of each print, 3D printing techniques have been more widely adopted worl...
Telenfermagem na pessoa transplantada ao coração
Loureiro, Maria; Duarte, João; Simões, Ricardo; Martins, Maria Manuela; Mota, Liliana; Novo, AndréAs pessoas transplantadas ao coração (TC) necessitam de acompanhamento que facilite a sua gestão de saúde nos diferentes domínios e da sua qualidade de vida após a alta hospitalar. A telenfermagem permite a interação remota com o cidadão, permitindo prevenir, avaliar, diagnosticar e intervir, sendo fundamental perceber as áreas de intervenção no caso específico da pessoa transplantada ao coração. Objetivos: Map...
Multi-Objective and Multi-Load Topology Optimization and Experimental Validatio...
Francisco, Paulo; Faria, Luis; Simões, RicardoThis work focuses on designing materials for elasticity and coupled fluid flow and heat transfer. The macroscale equations for homogenized elasticity and coupled fluid flow and heat transfer are presented. The topology optimization problem is formulated, its implementation detailed, and the design sensitivities of the homogenized coupled fluid flow and heat transfer problem deduced. Using the Method of Moving A...
Guiding principles of materials selection for product designers
Félix, Maria João; Ferreira, Pedro; Santos, Gilberto; Simões, Ricardo; Martins, JoãoThis work intends to analyze the importance of the materials selection process for the development of a new product. The aspects that influence the selection of materials in the Design process are due to the fact that these collaborate in the materialization of a project, stimulating a better interaction in the utilization of the products and consequently in the improvement of the people’s quality of life. The ...
Ergodesign: Visual analysis of entry (ingress) and exit (egress) car behaviour ...
F. Fernandes, Susana C.; Esteves, J. L.; Simões, Ricardo; Sampaio, João NunesThe natural aging process induces physical limitations, intending with this article analyze the behavior of senior and pre-senior drivers during ingress and egress of cars. The goal is to identify the parts of the interior of the car that should be changed or adjusted to the physical condition of these drivers to facilitate the executive function of getting in andout. The methodological process is based on visu...
