Nodulation, arbuscular mycorrhizal colonization and growth of some legumes native from Brazil
Patreze, Camila M.;Cordeiro, Lázara;
Acta Botanica Brasilica , 2005, DOI: 10.1590/S0102-33062005000300014
Abstract: the effects of rhizobial and mycorrhizal inoculation, nitrogen and phosphorus fertilization on nodulation, mycorrhizal colonization and initial growth were examined in brazilian native plants, enterolobium contortisiliquum (vell. conc.) morong, inga laurina (sw.) willd., lonchocarpus muehlbergianus hassl and platypodium elegans vogel. the experiment was carried out in a glasshouse using plastic bags filled with a mixture of sandy soil from riparian forest and vermiculite (2:1) amended with basal nutrients including np, p and n and infected with rhizobia (r), mycorrhiza (m) or both (rm), amounting seven treatments: np, p, p+r, p+rm, n, n+m and n+rm, with ten replications each. the plants were analyzed at 120 and 255 days after sowing. p deficiency negatively affected growth and nodulation of all species. autochton arbuscular mycorrhizal fungi (amf) colonized host roots and fungal inoculations did not enhance mycorrhizal colonization, which was also favored by added p. nodulation was relatively higher in e. contortisiliquum and l. muehlbergianus, mainly in treatments containing p, and with rhizobial inoculation (p+r). plants from these treatments developed better than others and, despite the rhizobia inoculated had no synergistic relationship with inoculated amf, they also showed the best percentages of mycorrhizal colonization. moreover, these two species showed highest rates of acetylene reduction and highest leghemoglobin content. these results suggest that e. contortisiliquum and l. muehlbergianus can have advantages for establishment in soils with low nitrogen levels.
Detailing the Structure of Liquid THF Based on an EPSR Study  [PDF]
Alexandre Borges, Jo?o M. M. Cordeiro
Computational Chemistry (CC) , 2015, DOI: 10.4236/cc.2015.31001
Abstract: The structure of pure liquid tetrahydrofuran (THF) has been investigated via Monte Carlo simulations in the wake of a previous Empirical Potential Structure Refinement (EPSR) study on that liquid (Bowron, D.T.; Finney, J.L.; Soper, A.K. (2006) J. Am. Chem. Soc., 128, 5119). The molecules are allatoms rigid structures and the intermolecular potential used is described for the classical 6-12 Lennard-Jones plus Coulomb in the NPT ensemble at 1 atm and 25°C. THF is a poorly structured liquid. Typical preferred orientation of molecules has been explored and calculations shown different types of molecular pairs exist concurrently in the liquid. The geometry of those pairs was deeply investigated and its influence in the liquid structure discussed. The lack of molecular organization in the liquid is closely related to the existence of that diversity of molecular pairs. Its geometry changes from antiparallel up to T-like depending on the distance between the molecules in the pairs.

Abstract: monte carlo simulations have been performed to investigate the structure and hydrogen bonds formation in liquid acetaldehyde. an all atom model for the acetaldehyde have been optimized in the present work. theoretical values obtained for heat of vaporisation and density of the liquid are in good agreement with experimental data. graphics of radial distribution function indicate a well structured liquid compared to other similar dipolar organic liquids. molecular mechanics minimization in gas phase leads to a trimer of very stable structure. the geometry of this complex is in very good agreement with the rdf. the shortest site-site correlation is between oxygen and the carbonyl hydrogen, suggesting that this correlation play a important role in the liquid structure and properties. the o×××h average distance and the c-h×××o angle obtained are characteristic of weak hydrogen bonds.

Borgismo, Coronelismo e dissidências políticas nas páginas dos jornais santa-marienses
Márcio Alex Cordeiro Biavaschi
BIBLOS : Revista do Instituto de Ciências Humanas e da Informa??o , 2005,
Abstract: Este artigo analisa o modo como a imprensa político-partidária na cidade de Santa Maria durante a Primeira República, sobretudo no período de governo de Borges de Medeiros, proporcionou a constru o de um imaginário simbólico e político das fac es políticas locais, enquanto portadores, produtores e reprodutores de sentidos. Esse momento histórico correspondeu, em Santa Maria, a constantes conflitos intrapartidários no seio do PRR local que se tornaram de conhecimento da esfera pública estadual da época, por meio da propaga o daqueles casos políticos nas páginas dos jornais, amparados e combatidos pelos coronéis locais em suas disputas políticas regionalizadas.
A áRVORE E A FLORESTA: UMA CONTRIBUI O METODOLóGICA DE PIERRE BOURDIEU ACERCA DA HISTóRIA REGIONAL

Revista de História Regional , 2007,
Abstract: This paper aproaches an analisys of Local History, started from teoric reflections of Pierre Bourdieu, specialty the field and simbolic power conceits. For this, we try to understand the context of Santa Maria da Boca do Monte City, placed on geografic center of Rio Grande do Sul, in the period of the First Republic, analising the particular experience of coronelismo. Este artigo aborda uma perspectiva de análise da história regional a partir da utiliza o dos referenciais teóricos formulados por Pierre Bourdieu, especialmente atendo-se aos conceitos de campo e poder simbólico. Para tal intuito, contextualiza o espa o ocupado pelo município de Santa Maria da Boca do Monte, localizado no centro geográfico do Rio Grande do Sul, no período delimitado da Primeira República, ao analisar a ocorrência de práticas articulares de coronelismo.

Abstract: O presente estudo foi realizado junto ao Grupo de Teatro para Atores Especiais (G.T.P.A.ê.), um projeto de extens o da Universidade Estadual de Londrina (UEL). O estudo teve como principal objetivo compreender os aspectos sociais, cognitivos e afetivos de pessoas com deficiência mental por meio da análise da estrutura e conteúdo de seu discurso. Procurou-se também verificar a eficácia do projeto na promo o de inclus o social e desenvolvimento de habilidades e autonomia dos membros do grupo. Participaram do estudo nove jovens com deficiência mental. Sete estagiários do curso de psicologia registraram durante os laboratórios de teatro as “verbaliza es de destaque” dos participantes, ou seja, aquelas que expressavam habilidades e limita es, sentimentos positivos e negativos, auto-percep o e observa es do meio. As falas foram transcritas literalmente, assim como o contexto no qual ocorreram; foram organizadas em categorias e analisadas. Para a analise geral, foi criado um roteiro contendo os seguintes aspectos: complexidade das falas; organiza o cognitiva; qualidade do conteúdo e autonomia das falas. De um modo geral, os participantes apresentaram falas coerentes, com estruturas e conteúdos diversos, que indicaram amplia o da autonomia e complexidade, o que apontou para contribui es da interven o. Através deste estudo foi possível compreender melhor cada participante mediante seu discurso sobre si mesmo e sobre o mundo; bem como sugerir e direcionar mudan as referentes às necessidades a serem trabalhadas tanto no plano individual como no grupal. Nossa sociedade necessita de estudos que se preocupem com a constru o da criticidade e autonomia de pessoas com deficiência mental Palavras-chave: Deficiência Mental. Análise de Discurso. Teatro.
