Mendes, Paulo J.; Santos, A.M.; Garcia, M.H.; Silva, T.J.; Robalo, M.P.A comutação das propriedades ópticas não-lineares (NLO) é de grande interesse na área da optoelectrónica e fotónica. O conceito de comutação molecular com base nas propriedades de NLO baseia-se na possibilidade de conseguir uma mudança na resposta óptica não linear entre duas formas ('on' e 'off'), desde que essas duas formas moleculares possuam uma grande diferença na magnitude das respectivas hiperpolarizabil...

Ono,E.; Santos,A.M. Nunes dos; Succi,R.C. de Menezes; Machado,D.M.; Angelis,D.S.A. de; Salomão,R.; Kallás,E.G.; Moraes-Pinto,M.I. deThe immune consequences of in utero HIV exposure to uninfected children whose mothers were submitted to highly active antiretroviral therapy (HAART) during gestation are not well defined. We evaluated 45 HIV-exposed uninfected (ENI) neonates and 45 healthy unexposed control (CT) neonates. All HIV-infected mothers received HAART during pregnancy, and the viral load at delivery was <50 copies/mL for 56.8%. Twenty...

Do socioeconomic factors explain why maternal smoking during pregnancy is more ...
Ribeiro,V.S.; Figueiredo,F.P.; Silva,A.A.M.; Batista,R.L.F.; Barbieri,M.A.; Lamy Filho,F.; Alves,M.T.S.S.B.; Santos,A.M.; Bettiol,H.The prevalence of smoking during pregnancy in Ribeirão Preto, a rich Brazilian city, was significantly higher (21.4%) than in São Luís (5.9%), a less developed city. To assess which variables explain the difference in prevalence of smoking during pregnancy, data from two birth cohorts were used, including 2846 puerperae from Ribeirão Preto, in 1994, and 2443 puerperae from São Luís, in 1997/98. In multivariable...

Characterization of the volatile fraction emitted by phloems of four pinus spec...
Santos, A.M.; Vasconcelos, T.; Mateus, E.; Farrall, M.H.; Silva, M. D. R. Gomes da; Paiva, Maria Rosa; Branco, M.Pine forests constitute some of the most important renewable resources supplying timber, paper and chemical industries, among other functions. Characterization of the volatiles emitted by different Pinus species has proven to be an important tool to decode the process of host tree selection by herbivore insects, some of which cause serious economic damage to pines. Variations in the relative composition of the ...
Strain-induced shifts of the zone-center phonons of III-Nitrides
Alves,H. W. Leite; Alves,J. L. A.; Santos,A. M.; Scolfaro,L. M. R.; Leite,J. R.In this work, by using the density-functional theory within the local density approximation, plane wave expansions and the pseudopotential method, we present our preliminary results for the strain-induced shifts of the zone center phonon modes and of the effective charges on the III-Nitrides. Our results are in good agreement with the experiment as well as with other calculations, whenever a comparison is possi...
Relativistic equations of state at finite temperature
Santos,A. M. S.; Menezes,D. P.In this work we study the effects of temperature on the equations of state within a relativistic model, with the inclusion of the baryons of the octet over a wide range of densities. We compare the results of the equation of state, effective mass and strangeness fraction for the TM1, NL3 and GL sets of parameters.
Ab initio calculation of the (100) and (110) surface phonon dispersion of GaAs ...
Alves,H. W. Leite; Alves,J. L. A.; Santos,A. M.; Scolfaro,L. M. R.; Leite,J. R.In this work, we have calculated ab initio the phonon dynamics of the Ga-rich GaAs (100) (1 × 1), GaAs (100) (2 × 1), GaN (100) (1 × 1), GaAs (110) and GaN (110) surfaces. Our results for the (100) surfaces show that, while the (2 × 1) reconstruction is characterized by dimer vibrations, the (1 × 1) reconstruction presents interesting features which is closely related to the reduced mass of the compound. All th...
