Nanostructured label–free electrochemical immunosensor for detection of a Parki...
Carneiro, Pedro; Loureiro, Joana A.; Delerue-Matos, Cristina; Morais, Simone; Pereira, Maria do CarmoAggregation of α-synuclein has been recognized as a critical event in the pathogenesis of Parkinson's disease whose prevalence is increasing with great socio-economic challenges for future generations. Here, we developed a sensitive and specific electrochemical immunosensor for the detection and quantification of this biomarker, based on the voltammetric study of a redox indicator signal, which decreases upon t...
An analysis on the Implementation of Secure Web-related Protocols in Portuguese...
Júnior, Jackson Barreto Costa; Carneiro, Pedro; Paiva, Sara; Pinto, PedroThe services supporting the websites, both public and private entities, may support security protocols such as HTTPS or DNSSEC. Public and private entities have a responsibility to ensure the security of their online platforms. Entities in the public domain such as city councils provide their services through their websites. However, each city council has its systems, configurations, and IT teams, and this mean...

BIM em projeto para manufatura e montagem na indústria AECO 4.0: metodologia pa...
Santos, Tiago; Figueiredo, Bruno; Pires, Miguel; Carneiro, PedroA integração de conceitos de Projeto para Manufatura e Montagem (Design for Manufacturing and Assembly ‑ DfMA) na indústria AEC potencia‑se pelo recurso a ferramentas BIM. DfMA considera os meios de produção e montagem no momento de desenvolvimento de um produto, ou projeto, na sua otimização. Este artigo foca‑se numa investigação que desenvolve metodologias de DfMA em para processos de pré‑fabricação, a serem ...
The simpler the better: Highly sensitive 17α-ethinylestradiol sensor based on a...
Torrinha, Álvaro; Carneiro, Pedro; Dias, Diana; Delerue-Matos, Cristina; Morais, SimoneThe remarkable features of a carbon fiber paper sensor (CP) were employed for detection of the estrogenic hormone 17α-ethinylestradiol (EE2), considered a contaminant of emerging concern due to its potential ecotoxicity and widespread in the aquatic ecosystems. In this work, an unpreceded CP pre-treatment study was conducted with the (Il)-hexacyanoferrate(III) ion pair, however a bare sensor without pre-treatme...
The value of private schools: evidence from Pakistan
Carneiro, Pedro; Das, Jishnu; Reis, HugoUsing unique data from Pakistan we estimate a model of demand for differentiated products in 112 rural education markets with significant choice among public and private schools. Families are willing to pay substantially for reductions in distance to school, but in contrast, price elasticities are low. Using the demand estimates, we show that the existence of a low fee private school market is of great value fo...
Modelling of elastic modulus of CaZrO3-MgO composites using isotropic elastic a...
Nunes-Pereira, J.; Carneiro, Pedro; Maceiras, Alberto; Baudin, Carmen; Pereira Silva, AStarting from synthetic raw materials (CaZrO3 and MgO), microstructural and mechanical properties were optimised in order to obtain dense multiphasic ceramic, then finite element method (FEM) of an equimolar (1:1) CaZrO3-MgO composite was performed in order to obtain the effective elastic modulus. Composite presents two main phases of orthorhombic CaZrO3 (81.5 wt.%) and cubic MgO (18.5 wt.%); For 1500 °C, relat...
Please call me John: name choice and the assimilation of immigrants in the Unit...
Carneiro, Pedro; Lee, Sokbae; Reis, HugoThe majority of immigrants to the United States at the beginning of the 20th century adopted American first names. In this paper we study the economic determinants of name choice, by relating the propensity of immigrants to carry an American first name to the local concentration of their compatriots and local labor market conditions. We find that high concentrations of immigrants of a given nationality discoura...
Produtividade de uma pastagem submetida a regimes de fertilização anual com azo...
Raimundo, Soraia; Arrobas, Margarida; Felix, Alberto; Vergueira, Ana; Martins, Carolina; Ribeiro, Emanuel; Faria, Inácio; Silva, Jessica Lana MenezesEste estudo tem como objetivo avaliar o efeito de longo prazo da fertilização de um lameiro na recuperação dos nutrientes aplicados e na produção de biomassa. Os lameiros são característicos de zonas de montanha, onde existe reduzida experiência da prática de fertilização com fertilizantes minerais. O ensaio está instalado em Bragança desde a primavera de 2013. Os regimes de fertilização em estudo são aplicação...
Nanomaterials towards Biosensing of Alzheimer’s Disease Biomarkers
Carneiro, Pedro; Morais, Simone; Pereira, Maria CarmoAlzheimer's disease (AD) is an incurable and highly debilitating condition characterized by the progressive degeneration and/or death of nerve cells, which leads to manifestation of disabilities in cognitive functioning. In recent years, the development of biosensors for determination of AD's main biomarkers has made remarkable progress, particularly based on the tremendous advances in nanoscience and nanotechn...
