Avaliação do desenvolvimento psicomotor no Exame Global de Saúde aos 5-6 anos
Braga-Tavares, Hugo; Santos, Helena; Dinis, Mª José; Teles, Andreia; Lopes, Ana; Ferreira, Teresa; Marques, Adelaide; Aires Pereira, SusanaIntrodução: Apesar de incluída no Exame Global de Saúde dos 5-6 anos (EGS 5-6), a avaliação do Desenvolvimento Psicomotor (DPM) não é realizada de forma sistemática havendo, também, alguma dificuldade na valorização e interpretação dos achados encontrados. Objectivo: Elaborar um instrumento de rastreio de perturbações do DPM e de indicadores de risco de perturbações específicas de aprendizagem a aplicar aos 5-6...

Segmentation Algorithms for Ear Image Data towards Biomechanical Studies
Ana Ferreira; Fernanda Gentil; João Manuel R. S. TavaresIn recent years, the segmentation, i.e. the identification, of ear structures in video-otoscopy, computerised tomography (CT) and magnetic resonance (MR) image data, has gained significant importance in the medical imaging area, particularly those in CT and MR imaging. Segmentation is the fundamental step of any automated technique for supporting the medical diagnosis and, in particular, in biomechanics studies...
Determinação de tetraciclinas em leite por cromatografia de camada fina
Lemos, Ana Ferreira de; Almeida, Ana Margarida Figueiredo de; Medeira, João Martins; Rodrigues, Ana LúciaAs tetraciclinas são compostos antibacterianos utilizados em bovinos de leite para tratamento de doenças infecciosas, como a mastite, mas também como aditivos em ração animal. O uso das tetraciclinas pode conduzir à presença de resíduos destes fármacos no leite, principalmente se não forem utilizados de acordo com as indicações, nem respeitado o período mínimo de eliminação dos antibióticos pelo leite. A presen...
Cost optimal levels for envelope components in residential building renovation ...
Almeida, Manuela Guedes de; Rodrigues, Ana; Ferreira, MarcoEnergy Efficiency in Buildings has been gaining increasing relevance in the past decades due to the raise of the energy consumption in the building sector as a consequence of the modern way of living with higher comfort patterns. In Europe, buildings are responsible for 40% of the energy consumption, which turns them into an important target for carbon emissions’ reduction [1]. Energy efficiency should be a mai...
Cost optimality and nZEB target in the renovation of Portuguese building stock ...
Almeida, Manuela Guedes de; Rodrigues, Ana; Ferreira, MarcoImproving energy efficiency in existing buildings is a great challenge. These buildings have their own limitations related with their design, location and function. To study the possibilities of cost-effectively improve the thermal performance of these buildings and increase the chances of reaching the nearly zero energy (nZEB) target, one building of Rainha Dona Leonor neighborhood has been analyzed. The purpo...
Use of UFLC-PDA for the analysis of organic acids in thirty five species of foo...
Pereira, Carla; Barros, Lillian; Carvalho, Ana; Ferreira, Isabel C.F.R.Analysis of organic acids has become increasingly important due to their role in the physiological activity of plants, and many separation methods have been developed for the simultaneous determination of these compounds in plant samples. Herein, ultra fast liquid chromatography and photodiode array detection (UFLC-PDA) was applied to the analysis of organic acids in young shoots, leaves, aerial parts and flowe...
Comparative evaluation of antimutagenic and antimitotic effects of Morchella es...
Stojković, Dejan; Davidović, Slobodan; Živković, Jelena; Glamočlija, Jasmina; Ćirić, Ana; Ferreira, Isabel C.F.R.; Soković, MarinaMorchella esculenta (L.) Pers. methanolic extracts, obtained from fruiting bodies growing wild in Serbia and Portugal, were screened for their antimutagenic properties and compared to protocatechuic acid, previously identified in both species. Salmonella typhimurium TA100 reversion assay was used for the antimutagenic properties. Methanolic extracts expressed important antimutagenic potency towards S. typhimuri...
A method to automatically segment the internal ear structures in CT images
Ana Ferreira; Francisco Oliveira; Fernanda Gentil; João Manuel R. S. TavaresHereby it is presents a novel methodology to segment the internal structures of the human ear based on image registration. The first step of the methodology concerns the registration of the volumetric image to be segmented with a reference volumetric image previously defined and manually segmented. Then, the geometric transformation found in the registration step is applied to the image to be segmented and cons...
