O grupo araxá na região sul-sudoeste do estado de goiás

In the S - SW region of Goiás State, Brazil, the Araxá Group is constituted of a metasedimentary sequence containing schistose and gneissic (garnet-biotite-quartz schists, feldspatic garnet-biotite-quartz schists, garnet-biotite-quartz paragneisses, with muscovite and locally amphibole, epidote, kyanite and staurolite. This sequence presents intercalations of metaul-tramafc rocks (serpentinite, actinolite schist, talc schist, chlorite schist), metamafc ones (amphibolite, amphibole schist containing or not garnet, garnet amphibolite) and associated granitic bodies. Chemically, the Araxá Group metasediments present peraluminous composition, showing enrichment in LILE, when compared with HFSE and REE, and displaying negative anomalies of Nb, Ta, Sr, P and Ti. Their chemical composition is that of greywake and the chemical characteristics of the sediments are generated in magmatic arcs. Isotopic data for Sm/Nd - model ages (TDM) between 1,04 - 1,51 and 1,76 - 2,26 Ga - and U/Pb (predominance of zircon with ages < 900 Ma) suggest that these metasediments have Neoproterozoic rocks as the source rocks. Chemical and isotopic characteristics of the studied metasediments suggest that their source are rocks originated in magmatic arcs and that they were deposited in a fore arc basin developed in the margins of Neoproterozoic island arcs.

Desempenho produtivo e qualidade pós-colheita de genótipos de feijão do grupo comercial carioca cultivados na época de inverno-primavera

The objective of this work was to evaluate the agronomic performance and grain quality, especially the grain technological characteristics in the common bean genotypes, cultivated in winter-spring season. The experiment was carried out in Jaboticabal-SP, in a Rhodic Hapludox. The experimental design was a randomized block with 17 treatments (genotypes) with three replications. The plots had been composed for 17 carioca common bean group genotypes (Pérola, BRS Cometa, BRS Pontal, IPR Juriti, CNFC 10703, CNFC 10713, CNFC 10716, CNFC 10721, CNFC 10729, CNFC 10733, CNFC 10742, CNFC 10753, CNFC 10757, CNFC 10758, CNFC 10762, CNFC 10763 and CNFC 10813). BRS Pontal and CNFC 10716 showed simultaneously the higher number of per plant and grain yield. The technological characteristics more expressive was verified in CNFC 10703, CNFC 10713, CNFC 10758, CNFC 10813 and CNFC 10716 genotypes, principally about the protein content, cooking time and grain hydration capacity. The CNFC 10716 genotype detached as promissory, because their elevated agronomic performance and satisfactory technological characteristics.

Efeito de grupo versus produção de CO2 em operárias da formiga cortadeira Atta sexdens rubropilosa

Does the social life entail greater individual activity, and consequently, higher energy expenditure? To answer this question, we hypothesized that there is higher CO2 production, when we increase the size of the group of workers, and hence a higher energy cost to the individual when they are in groups. Thus, groups of 10, 20, 30, 40 and 50 workers were sealed in a hermetic chamber for 24 hours. Subsequently, we performed the measurements of the CO2 concentration in the containers respirometric. Unlike the expected CO2 production, and consequently the individual energy expenditure did not differ when we increase the size of the group of workers. Thus, we refuted the hypothesis that the group size leads to a higher cost individual energy, since the greater interaction between individuals. In conclusion, our study with Atta sexdens rubropilosa workers determined that the size of the group does not lead to higher energy costs individual and CO2 production, and therefore energy expenditure similar individual, independent of the group size.

Comportamento de poedeiras criadas a diferentes densidades e tamanhos de grupo em ambiente enriquecido

The objective of this work was to determine the behavioral differences among laying hens reared at different densities and group sizes, in an enriched environment. Isa Brownlaying hens with ages from 30 to 32-week-old, in small-sized and deformed pens, were used. Hens were raised during 28 days in bays with shavings bedding, perch and nest. Two group sizes were evaluated (6 and 12 fowls) and at two rearing densities (774 and 1,440 cm2 by fowl) in a factorial arrangement with three replicates. In fifteen-minute video footages, it was recorded the frequency and the expression period for the following behavior were recorded: feather scratching, sand bath, wing beating, drinking water, pecking, head scratching, earth scratching, eating, perching, leg stretching, pursuing, sitting, and nest visiting. The treatments and the interaction between them had significant effects. The six-hen group increased the frequency of behavior types that indicate fowl frustration, regardless of density. The group size is the most important factor for hen well-being.
