Engagement of multifocal neural circuits during recall of autobiographical happ...
Cerqueira,C.T.; Almeida,J.R.C.; Gorenstein,C.; Gentil,V.; Leite,C.C.; Sato,J.R.; Amaro Jr.,E.; Busatto,G.F.Happy emotional states have not been extensively explored in functional magnetic resonance imaging studies using autobiographic recall paradigms. We investigated the brain circuitry engaged during induction of happiness by standardized script-driven autobiographical recall in 11 healthy subjects (6 males), aged 32.4 ± 7.2 years, without physical or psychiatric disorders, selected according to their ability to v...
Late-life depression, heart failure and frontal white matter hyperintensity: a ...
Almeida,J.R.C.; Alves,T.C.T.F.; Wajngarten,M.; Rays,J.; Castro,C.C.; Cordeiro,Q.; Telles,R.M.S.; Fraguas,R.J.; Busatto,G.F.The relevance of the relationship between cardiac disease and depressive symptoms is well established. White matter hyperintensity, a bright signal area in the brain on T2-weighted magnetic resonance imaging scans, has been separately associated with cardiovascular risk factors, cardiac disease and late-life depression. However, no study has directly investigated the association between heart failure, major dep...
The influence of the mode II fracture energy on the behaviour of composite plat...
Neto, P.; Alfaiate, J.; Almeida, J. R.; Pires, E. B.; Vinagre, JoãoComunicação apresentada em Fifth International Conference on Fracture Mechanics of Concrete and Concrete Structures, Vail, Colorado, USA, 2004 ; In this paper, the finite element method is used to analyse the behaviour of concrete externally strengthened by sheets of carbon fibre reinforced polymer (CFRP). The bond between concrete and CFRP is modelled by a discrete approach using interface elements. The mecha...
Outros constituintes químicos de Diplotropis ferruginea Benth. (Fabaceae)
Almeida,J.R.G.S.; da-Cunha,E.V.L.; Silva,M.S.; Athayde-Filho,P.F.; Braz-Filho,R.; Barbosa-Filho,J.M.O extrato hexânico das cascas do caule de Diplotropis ferruginea Benth (Fabaceae), após procedimentos cromatográficos e fitoquímicos, forneceu o triterpeno lupeol, citado pela primeira vez em Diplotropis ferruginea, e etil-2-hidroxi-4-methoxi-6-propil-benzoate, descrito pela primeira vez em na literatura. As determinações estruturais desses compostos foram realizadas com base em análises espectroscópicas de ¹H ...
On the entropy of the Viana-Bray model
Almeida,J.R.L. deThe entropy of the Viana-Bray model at zero temperature and external field is calculated within the solution which takes into account only delta functions for the global order parameter P(h). It is shown that such solution is unsatisfactory both from the viewpoint of stability analysis and for not reproducing the well known Sherrington-Kirkpatrick result in the large connectivity limit thus pointing out the rel...
Quantifying a certain ''advantage law'': minority game with above the rules agents
Almeida,J.R.L de; Menche,J.In this work the properties of minority games containing agents which try to winning all the time are studied by means of computational simulations. We have considered several ways of introducing above the rules clever players using ''strategies'' which try to outdo the others endowed with statistically equivalent strategies and compared the resulting behaviors of the ensemble. It is shown that by introducing s...

Application of deterministic model of isothermals for population dynamics of Sy...
ALMEIDA,J. R. de; OLIVEIRA,S. G. de; BORGES,I. L.; D'ALMEIDA,J. M.The isothermal deterministic model adherence was studied to evaluate the population dinamic of Synthesiomyia nudiseta (Diptera, Muscidae). The linear form of equation obtained for the experiments in the several phases, were for Egg: 1/D = -0.18 + 0.02 . T; Larva: 1/D = -0.028 + 0.01. T; Pupa: 1/D = -0.069 + 0.01 . T; and Adult: 1/D = -0.4178 + 0.02 . T. In function of temperature, S. nudiseta can present from 4...
Entomological fauna from Reserva Biológica do Atol das Rocas, RN, Brazil: I. Mo...
ALMEIDA,C. E. de; MARCHON-SILVA,V.; RIBEIRO,R.; SERPA-FILHO,A.; ALMEIDA,J. R. de; COSTA,J.Atol das Rocas, the unique atoll in the South-western Atlantic, is located 144 nautical miles (266 Km) northeast from the city of Natal, NE Brazil and 80 nautical miles from Arquipélago de Fernando de Noronha, with geographic co-ordinates 3º51'S and 33º49"W. It's of volcanic origin and coralline formation. The reef is ellipsoid, its largest axis (E-W) is approximately 3.7 km long, and the shortest (N-S) is 2.5 ...
Nichos tróficos em dípteros caliptrados, no Rio de Janeiro, RJ
d'ALMEIDA,J. M.; ALMEIDA,J. R.Foram calculadas a extensão e sobreposição de nichos tróficos de dípteros caliptrados, criados em variados ambientes do Rio de Janeiro (área rural, urbana e florestal), utilizando-se diferentes substratos de criação (banana amassada, carcaça de camundongo, peixe (sardinha), fígado bovino, camarão e fezes humanas frescas. Foram criadas 14.294 moscas, pertencentes às famílias Calliphoridae, Fanniidae, Muscidae e ...
