MACROSCOPIC LESIONS ON THE GREY TRIGGERFISH, BALISTES CAPRISCUS (PISCES) ASSOCI...
Ramos, P.; Ruano, F.; Jesus, D.; Cruz, TeresaFifteen live specimens of Conchoderma virgatum were attached to a grey triggerfish (Balistes capriscus) caught in S.W. Portugal. The barnacles were distributed in three groups (right abdominal external face, anterior side of the insertion of the pelvic spine, and close to (5 mm) the left eye (on the lacrymal bone)). The specimens were very different in size, ranging from 2 mm to 18.9 mm (maximum capitular lengt...
Sedimentologia e Estratigrafia –Estudo de um terraço de Lavadores. Contri...
H. Ribeiro; A. Pinto de Jesus; D. Mosquera; I. Abreu; J. R. Vidal Romaní; F. NoronhaSedimentological studies of the terrace of the Pedras Amarelas in Lavaores (Vila Nova de Gaia) suggest, from the bottom up and to the migration of sedimentary environments to the west, the existence of coastal intertidal sedimentation, from the river sedimentation and culminating with swampy environments/lagoon in which there is evidence periglaciation. Geochronological studies conducted by OSL and 14C dating a...
Effect of potential shape on the density of the impurity states in nanotube
Orozco,Eduardo A.; González,Jesús D.; Barrera,Martha L.We analyze the effect of the potential shape on the ground state energy of the off-axis neutral donor in GaAs/Ga1-xAl xAs cylindrical nanotube in the presence of the uniform magnetic field applied along the symmetry axis. To take into account the mixing of the low lying subbands we express the wave function as a product of combination of 1s and 2p x,y wave functions with an unknown envelope function that depend...
Evaluation of solubility, disintegration, and dimensional alterations of a glas...
Carvalho-Júnior,Jacy Ribeiro; Guimarães,Luiz Fernando L.; Correr-Sobrinho,Lourenço; Pécora,Jesus D.; Sousa-Neto,Manoel D.The aim of this study was to evaluate the glass ionomer cement Ketac-Endo (K) compared with Endofill (E), N-Rickert (N), and Sealer 26 (S) in terms of disintegration, solubility, and dimensional alteration properties, based on ADA Specification No 57. For dimensional alterations, 12-mm high cylindric specimens measuring 6 mm in diameter were prepared and left to stand for a period corresponding to three times t...
Mechanism of action of sodium hypochlorite
Estrela,Carlos; Estrela,Cyntia R.A.; Barbin,Eduardo Luis; Spanó,Júlio César E.; Marchesan,Melissa A.; Pécora,Jesus D.The choice of an irrigating solution for use in infected root canals requires previous knowledge of the microorganisms responsible for the infectious process as well as the properties of different irrigating solutions. Complex internal anatomy, host defenses and microorganism virulence are important factors in the treatment of teeth with asymptomatic apical periodontitis. Irrigating solutions must have expressi...
Evaluation of the efect of EDTA, EGTA and CDTA on dentin adhesiveness and micro...
Sousa-Neto,Manoel D.; Passarinho-Neto,Jarbas Gonçalves; Carvalho-Júnior,Jacy Ribeiro; Cruz-Filho,Antonio M.; Pécora,Jesus D.; Saquy,Paulo CésarThe effect of chelating solutions EDTA, EGTA and CDTA on human dentin adhesiveness and microleakage with 4 sealers (Sealer 26, Sealapex, N-Rickert and Endofill) was evaluated in vitro. Whether or not there was a mathematical correlation between the tests of adhesiveness and microleakage was also evaluated. A total of eighty maxillary and mandibular molars were used to test adhesiveness. After wearing of the occ...
Potencial alelopático de forrageiras tropicais: efeitos sobre invasoras de past...
Souza Filho,Antonio Pedro S.; Rodrigues,Luis Roberto A.; Rodrigues,Teresinha Jesus D.Extratos aquosos de sementes, parte aérea e raízes de três gramíneas e três leguminosas forrageiras foram preparados a uma concentração de 10%, com o objetivo de avaliar os efeitos potencialmente alelopáticos sobre a germinação de sementes e o alongamento da radícula das invasoras de pastagens: desmódio, guanxuma e assa-peixe. A germinação foi monitorada em períodos de dez dias, com contagens diárias e eliminaç...
