Experimental and theoretical studies of the second- and third-order NLO propert...
Silva, Pedro S. Pereira; Ouazzani, Hasnaa El; Pranaitis, Mindaugas; Silva, Manuela Ramos; Arranja, Cláudia T.; Sobral, Abilio J. F. N.A new semi-organic compound, 6-aminoquinolinium iodide monohydrate (I), has been synthesized and characterized by single crystal X-ray diffraction, UV–vis absorption and fluorescence spectroscopy and nonlinear optical (NLO) measurements. The second- and third-order NLO responses were investigated with the second- and third-harmonic Maker fringes techniques, carried out on thin films at a fundamental wavelength ...
Wearable biopotential measurement using the TI ADS1198 analog front-end and tex...
Pereira, Tiago; Carvalho, Helder; Catarino, André P.; Dias, M. J.; Postolache, Octavian; Girão, Pedro S.The development of mobile systems for monitoring bioelectric signals outside a hospital environment involves many challenges that do not arise when it is in a controlled environment, like a hospital. The dimensions of these systems are an important factor to consider in order to facilitate their use without interfering with the daily activities of individuals. The purpose of this work is the implementation of a...
Genomic Signatures and Antiviral Drug Susceptibility Profile of A(H1N1)pdm09
Tiago Gíria, M; Rebelo Andrade, H; Santos, LA; Correia, V; Pedro, S; Almeida Santos, MBackground: Genetic changes in influenza surface and internal genes can alter viral fitness and virulence. Mutation trend analysis and antiviral drug susceptibility profiling of A(H1N1)pdm09 viruses is essential for risk assessment of emergent strains and disease management. Objective: To profile genomic signatures and antiviral drug resistance of A(H1N1)pdm09 viruses and to discuss the potential role of mutate...
Continuous health monitoring using e-textile integrated biosensors
Catarino, André P.; Carvalho, Helder; Dias, M. J.; Pereira, Tiago; Postolache, Octavian; Girão, Pedro S.In this work, continuous health monitoring for disabled or elderly people is proposed using textile integrated electrodes for ECG measurement. Other applications, such as EMG or skin impedance measurement are also envisaged. The paper specifically describes a shirt integrating electrodes for ECG measurement that has been tested in several conditions. The techniques for integration of ECG electrodes can be direc...

Estimation of unemployment rates in small areas of Portugal: a best linear unbi...
Pereira, Luis Nobre; Mendes, J; Coelho, Pedro S.The high level of unemployment is one of the major problems in most European countries nowadays. Hence, the demand for small area labor market statistics has rapidly increased over the past few years. The Labour Force Survey (LFS) conducted by the Portuguese Statistical Office is the main source of official statistics on the labour market at the macro level (e.g. NUTS2 and national level). However, the LFS was ...
Mineral composition of Lippia alba (Mill.) N.E. Brown leaves
Reis,Pedro S. dos; Estevam,Idalia Helena S.; Santos,Wagna P. C. dos; Korn,Maria Graças A.; David,Jorge M.; David,Juceni P.; Araújo,Rennan G. O.Leaves of Lippia alba (Mill.) N.E. Brown are used for the preparation of tea infusions that are employed in folk medicine. In this paper, the mineral composition of Lippia alba (Mill.) leaves, collected from different Brazilian cities, was evaluated. The samples were digested using nitric acid and hydrogen peroxide on a hot plate and were analyzed using inductively coupled plasma optical emission spectrometry (...
Stilbenes from Deguelia rufescens var. urucu (Ducke) A. M. G. Azevedo leaves: e...
Lobo,Lívia T.; Silva,Geilson A. da; Freitas,Manolo C. C. de; Souza Filho,Antonio Pedro S.; Silva,Milton N. da; Arruda,Alberto C.The Amazon biodiversity may provide plants whose chemical substances are capable of controlling weeds. In this study we report the isolation and identification of five stilbenes from the leaves of "timbó vermelho" (Deguelia rufescens var. urucu): 4-methoxylonchocarpene (1); 3,5-dimethoxy-4´-hydroxy-3´-prenyl-trans-stilbene (2), lonchocarpene (3), 3,5-dimethoxy-4´-O-prenyl-trans-stilbene (4) and pterostilbene (5...
Nacionalidade das empresas e fluxo de empregos: evidências da indústria brasile...
Esteves,Luiz A.; Martins,Pedro S.A segunda metade da década de 90 é um período caracterizado por um grande aumento dos investimentos (e desinvestimentos) externos no Brasil. Essa mudança estrutural da economia brasileira é a motivação para este estudo, cujo objetivo é analisar o efeito da nacionalidade das empresas sobre o fluxo de empregos industrial. Trata-se de um tema sobre o qual há pouca evidência, mesmo para países desenvolvidos, embora...
Aspectos clínico-patológicos e imuno-histoquímicos de equídeos infectados pelo ...
Pedroso,Pedro M.O; Colodel,Edson M; Gomes,Danilo C; Varaschin,Mary S; Bezerra Júnior,Pedro S; Barbosa,José D; Tokarnia,Carlos H; Driemeier,DavidForam analisados 14 equídeos (13 equinos e 1 muar) com diagnóstico clínico e histológico de raiva provenientes de quatro regiões do Brasil. O curso clínico médio foi de quatro dias de evolução, incluindo incoordenação motora, paralisia dos membros pélvicos, paresia dos membros torácicos e decúbito. Os achados histopatológicos caracterizaram-se por meningoencefalite e meningomielite não supurativa com infiltrado...
