O acento em tupi antigo

O objetivo deste trabalho é estudar a lírica tupi de Pe. José de Anchieta, discutindo a possibilidade de análise do acento da língua tupi antiga, via métrica adotada pelo autor em seus poemas. De toda a sua obra poética, 18 poemas foram escritos inteiramente em língua tupi, 10 deles servindo como corpus para esta pesquisa. Como aporte teórico para essa análise foi utilizada a Fonologia não-linear - mais precisamente a Teoria Métrica de Hayes (1995) - e um modelo de abordagem baseado em Massini-Cagliari (1995,1999 e aorientações na área) para com o português arcaico. As poesias em enfoque foram observadas em várias versões da obra disponíveis (Anchieta 1954, 1984, 2004). Para a base do estudo tupi, foram utilizadas as gramáticas de Anchieta (1933) e Lemos Barbosa (1956), além de livros e textos de Navarro (2006a, 2006b) e Ayron Rodrigues (1958)

Informatização da coleção do Herbário José Pivetta

No ano de 2005 o Herbário Rioclarense (HRCB) recebeu em doação pelo Museu Vicente Pallotti a coleção de exsicatas mantida pelo fundador do referido museu Padre José Pivetta. A maioria dos espécimes consistia de amostras de pteridófitas e angiospermas obtidas durante as décadas de 1950 e 1960 no Estado do Rio Grande do Sul, contudo, há exemplares provindos das regiões Norte e Centro-Oeste brasileiras e algum exemplares argentinos. A coleção apresentava-se em precário estado de conservação sendo necessária imediata remontagem dos materiais não deteriorados pela ação do tempo e/ou microorganismos e preservação das etiquetas originais. Os dados contidos nas etiquetas confeccionadas principalmente pelo Pe. José Pivetta foram copilados para uma planilha de dados do tipo Microsoft®Excel® 2000 e as exsicatas foram integradas ao acervo do Herbário RioClarense da Universidade Estadual Paulista (UNESP) campus de Rio Claro. A informatização dos herbários, agilizando a busca de dados para as pesquisas em botânica e ciências afins e tornando as informações aí depositadas disponíveis para um público mais diversificado, é fundamental para o avanço da ciência, ao acelerar a troca de informações e facilitar o gerenciamento de coleções (Brito & Joly, 1999). O trabalho de taxonomistas e pesquisadores correlatos é amplamente beneficiado com a presença de herbários bem organizados cujo acervo encontra-se informatizado e disponível para acessos. Ao todo nesta coleção foram recuperadas 2306 exsicatas pertencentes a 144 famílias. Dentre as mais representativas pode-se citar as Asteraceae com 236 exemplares (10,23%), Fabaceae com 174 exemplares (7,54%) e Pteridaceae com 85 exemplares (3,69%). Apesar de grande parte da coleção possuir identificação parcial, 54 exsicatas (2,34%) não a possuem, fato este verificado...(Resumo completo, clicaracesso eletrônico abaixo)

Characteristics of the double-torsion test to determine the R-curve of ceramic materials

Double-torsion tests were carried out on a commercial ceramic floor tile to verify whether this test is suitable for determining the R-curve of ceramics. The instantaneous crack length was obtained by means of compliance calibration, and it was found that the experimental compliance underestimates the real crack length. The load vs. displacement curves were also found to drop after maximum loading, causing the stress intensity factor to decline. The R-curves were calculated by two methods: linear elastic fracture mechanics and the energetic method. It was obtained that the average values of crack resistance, R, and the double of the work of fracture, 2 · γwof, did not depend on notch length, a0, which is a highly relevant finding, indicating that these parameters were less dependent on the test specimen's geometry. The proposal was to use small notches, which produce long stable crack propagation paths that in turn are particularly important in the case of coarse microstructures.

Direct and indirect connections between cochlear root neurons and facial motor neurons: Pathways underlying the acoustic pinna reflex in the albino rat

Cochlear root neurons (CRNs) are involved in the acoustic startle reflex, which is widely used in behavioral models of sensorimotor integration. A short-latency component of this reflex, the auricular reflex, promotes pinna movements in response to unexpected loud sounds. However, the pathway involved in the auricular component of the startle reflex is not well understood. We hypothesized that the auricular reflex is mediated by direct and indirect inputs from CRNs to the motoneurons responsible for pinna movement, which are located in the medial subnucleus of the facial motor nucleus (Mot7). To assess whether there is a direct connection between CRNs and auricular motoneurons in the rat, two neuronal tracers were used in conjunction: biotinylated dextran amine, which was injected into the cochlear nerve root, and Fluoro-Gold, which was injected into the levator auris longus muscle. Under light microscopy, close appositions were observed between axon terminals of CRNs and auricular motoneurons. The presence of direct synaptic contact was confirmed at the ultrastructural level. To confirm the indirect connection, biotinylated dextran amine was injected into the auditory-responsive portion of the caudal pontine reticular nucleus, which receives direct input from CRNs. The results confirm that the caudal pontine reticular nucleus also targets the Mot7 and that its terminals are concentrated in the medial subnucleus. Therefore, it is likely that CRNs innervate auricular motoneurons both directly and indirectly, suggesting that these connections participate in the rapid auricular reflex that accompanies the acoustic startle reflex. © 2008 Wiley-Liss, Inc.

A fast cholinergic modulation of the primary acoustic startle circuit in rats

Cochlear root neurons (CRNs) are the first brainstem neurons which initiate and participate in the full expression of the acoustic startle reflex. Although it has been suggested that a cholinergic pathway from the ventral nucleus of the trapezoid body (VNTB) conveys auditory prepulses to the CRNs, the neuronal origin of the VNTB-CRNs projection and the role it may play in the cochlear root nucleus remain uncertain. To determine the VNTB neuronal type which projects to CRNs, we performed tract-tracing experiments combined with mechanical lesions, and morphometric analyses. Our results indicate that a subpopulation of non-olivocochlear neurons projects directly and bilaterally to CRNs via the trapezoid body. We also performed a gene expression analysis of muscarinic and nicotinic receptors which indicates that CRNs contain a cholinergic receptor profile sufficient to mediate the modulation of CRN responses. Consequently, we investigated the effects of auditory prepulses on the neuronal activity of CRNs using extracellular recordings in vivo. Our results show that CRN responses are strongly inhibited by auditory prepulses. Unlike other neurons of the cochlear nucleus, the CRNs exhibited inhibition that depended on parameters of the auditory prepulse such as intensity and interstimulus interval, showing their strongest inhibition at short interstimulus intervals. In sum, our study supports the idea that CRNs are involved in the auditory prepulse inhibition of the acoustic startle reflex, and confirms the existence of multiple cholinergic pathways that modulate the primary acoustic startle circuit. © 2013 Springer-Verlag Berlin Heidelberg.

A cultura afro-brasileira na sala de aula: uma proposta de trabalho pedagógio com obras que dialogam com o livro 'Três anjos mulatos do Brasil ', de Rui de Oliveira

The theme of African-Brazilian culture is still little explored in the school environment, in spite of the 10.639/03 law which prescribes its mandatory teaching as well as that of African-Brazilian history and African culture in all schools, public and private, from the Elementary School level to High School. Moreover, this law emphasizes the importance that these cultures had in the formation of Brazilian society. Considering this issue, this paper aims to analyze the work Três anjos mulatos do Brasil (2011), by Rui de Oliveira, which brings together three sensitive and touching biographies, followed by beautiful and artistic pictures. hese narratives address the genius of three great artists –Aleijadinho, Mestre Valentim and Father José Maurício–, their styles, their creations and struggle for recognition, as well as the sufering they experienced, primarily caused by racial discrimination. Also, we intend to present in this text a suggested pedagogical use of the work by Oliveira, by applying the “Recepcional” method, as it was deined by Bordini and Aguiar (1993).
