Over 100 mV VOC improvement for rear passivated ACIGS ultra‐thin solar cells
Oliveira, Antonio; Rocha Curado, Marco; Teixeira, J. P.; Tomé, Daniela; Çaha, Ihsan; Oliveira, Kevin; Lopes, Tomás; Monteiro, Margarida; Violas, AndréA decentralized energy system requires photovoltaic solutions to meet new aesthetic paradigms, such as lightness, flexibility, and new form factors. Notwithstanding, the materials shortage in the Green Transition is a concern gaining momentum due to their foreseen continuous demand. A fruitful strategy to shrink the absorber thickness, meeting aesthetic and shortage materials consumption targets, arises from in...
Cu(In,Ga)Se2 based ultrathin solar cells: the pathway from lab rigid to large s...
Lopes, Tomás; Teixeira, Jennifer; Curado, Marco; Ferreira, Bernado; Oliveira, Antonio; Cunha, José; Monteiro, Margarida; Violas, André; Barbosa, JoãoFor the first time, the incorporation of interface passivation structures in ultrathin Cu(In,Ga)Se2 (CIGS) based solar cells is shown in a flexible lightweight stainless-steel substrate. The fabrication was based on an industry scalable lithography technique - nanoimprint lithography (NIL) - for a 15x15 cm2 dielectric layer patterning, needed to reduce optoelectronic losses at the rear interface. The nanopatter...
Úlcera por pressão: caso clínico: dificuldade no diagnóstico diferencial
Miranda, Liliana; Pires, Patrícia; Oliveira, Antonio; Ramos, Paulo; Alves, PauloÉ necessário avaliar com precisão as Úlceras por Pressão (UPP) e planear os cuidados de acordo como tratamento das mesmas1. Estudos revelam que o conhecimento e a prática sobre a prevenção das UPP são insuficientes2, dificultando o diagnóstico diferencial e o tratamento.
Encapsulation of Nanostructures in a Dielectric Matrix Providing Optical Enhanc...
Oliveira, Antonio; de Wild, Jessica; Oliveira, Kevin; Valença, Beatriz A.; Guerreiro, Joana Rafaela; Abalde-Cela, Sara; Lopes, TomásThe incorporation of nanostructures in optoelectronic devices for enhancing their optical performance is widely studied. However, several problems related to the processing complexity and the low performance of the nanostructures have hindered such actions in real-life devices. Herein, a novel way of introducing gold nanoparticles in a solar cell structure is proposed in which the nanostructures are encapsulate...
A unified approach to the design of clinical reporting systems
Galvão de Melo, E.; Almeida, I.; Raposo, V. D.; Lopes, L.; Azevedo, A. P.; Salgado, N. C.; Oliveira, AntonioComputer-based Clinical Reporting Systems (CRS) for diagnostic departments that use structured data entry have a number of functional and structural affinities suggesting that a common software architecture for CRS may be defined. Such an architecture should allow easy expandability and reusability of a CRS. We report the development methodology and the architecture of SISCOPE, a CRS originally designed for gas...

Metadherin expression and lung relapse in patients with colorectal carcinoma
Casimiro, Sandra; Fernandes, Afonso; Oliveira, Antonio; Franco, Marco; Pires, Ricardo; Peres, Mafalda; Matias, Margarida; Tato-Costa, JoanaColorectal cancer (CRC) is the third most common malignant disease in men and the second in women worldwide. CRC relapse occurs mostly in liver and lungs, decreasing the 5-year survival to 6 %. Metadherin (MTDH) is overexpressed in several types of cancer, has been implicated in proliferation, invasion, metastasis, angiogenesis, and chemoresistance, and is a factor of poor prognosis in CRC. In this work we addr...
BREASTFEEDING AND OVERWEIGHT IN PRESCHOOL CHILDREN
Aparício, Graça; Cunha, Madalena; Albuquerque, Carlos; Duarte, João; Bonito, Jorge; Franco, Vitor; Rodrigues, Vitor; Oliveira, AntonioBackground: Scientific evidence shows that breastfeeding has a protective effect on the development of excess weight. Objectives: To determine the effect of breastfeeding on overweight children. Methods: Cross-sectional and observational study comprising 1424 preschool children, average age 4,58 years old (SD=0,990), residents in the centre/north region of Portugal. Children’s anthropometric measurement was obt...
The effect of education on age-related changes in three cognitive domains: a cr...
Martins, Isabel Pavão; Maruta, Carolina; Silva, Cláudia; Rodrigues, Pedro; Chester, Catarina; Ginó, Sandra; Freitas, Vanda; Freitas, SaraThe present study aims to investigate the protective effect of formal education on age-related changes in different cognitive domains with the hypothesis that it may attenuate the rate of decline. Individuals aged 50 years or older attending primary care physicians without known brain disease (431 participants, mostly [60.3%] female with 66.3 [±9.1] years of age and 7.7 [±4.1] years of education, on average), w...
A critical approach to nutritional assessment in critically ill patients
Ravasco, Paula; Camilo, M. E.; Oliveira, Antonio; Adam, S.; Brum, G.Background and aims: Nutritional assessment enhances quality of nutritional care, however, its practice bemuses professionals. This prospective study aimed to identify a feasible/informative nutritional parameter in intensive care. Methods: 44 patients (APACHE II: 23.8+/-10.1), age 58.4+/-18.6 years, were evaluated at admission: clinical data, height, weight, body mass index (BMI), tricep skinfold thickness, mi...
