Estudo da introdução de resíduo de britagem de rocha calcária e cinza de biomassa de cana-de-açúcar em formulações de argamassas colantes

The adhesive mortars are a mixture of cement, sand, and additives to polymers that retain the mixing water and promotes adherence, being used in setting on various ceramic substrates. The sand used in the production of these mortars is from the riverbeds, and with the increasing restriction of these sands extraction by environmental agencies, and often having to be transported over long distances to the consumer center. This work aims to design and physical and mechanical characterization of ecological adhesive mortar with total replacement of natural sand by sand from the crushing of limestone, and the addition of mineral ash biomass of cane sugar in partial replacement cement used in the production of adhesive mortar , aiming compositions that meet the regulatory specifications for use adhesive mortar. Standardized tests to determine the tensile bond strength (NBR 14081-4), determination of open time (NBR 14081-3) and determination of slip (NBR 14081-5) were performed. Were also conducted trials squeeze flow in different formulation, the mortar with addition of 15 % gray biomass of cane sugar for cement mortars as well as the total replacement of natural sand by sand limestone crushing, got the best performance among the mortars studied, it was found that the addition of biomass to replace cement is perfectly feasible due to its pozzolanic activity, which contributed to this reduction in the cement matrix formation of adhesive mortar

Diversidade genética em populações-núcleo de Eucalyptus grandis

No melhoramento genético de espécies florestais, uma população base ou indivíduos superiores pré-selecionados tem importância fundamental para a manutenção do programa. Indivíduos de melhores procedências e de ampla base genética propiciam a obtenção de ganhos de forma contínua. O objetivo deste trabalho foi avaliar a diversidade genética em duas populações-núcleo de Eucalyptus grandis. Foram avaliados 39 indivíduos, sendo 19 pertencentes à população 1 e 20, à população 2, utilizando-se 14 primers microssatélite. Os fragmentos foram identificados e analisados a partir dos programas GeneScan e Genotyper, utilizando-se um sequenciador automático ABI Prism 3100. O número de alelos encontrados para cada primer variou de cinco a 15 para a população 1 e, de 8 a 18 para a população 2. A heterozigosidade estimada foi maior na população 2, 0,869, contra 0,843 na população 1. A média da distância genética entre os indivíduos da população 1 foi 0,6220 e na população 2 foi 0,6112. Com a caracterização molecular dos indivíduos destas populações foi construído um banco de dados que permitirá, a partir dos parâmetros de genética de populações, monitorar esses programas de melhoramento em diferentes ciclos de seleção.

Dominance of legume trees alters nutrient relations in mixed species forest restoration plantings within seven years

Failures in reforestation are often attributed to nutrient limitation for tree growth. We compared tree performance and nitrogen and phosphorus relations in adjacent mixed-species plantings of contrasting composition, established for forest restoration on Ultisol soil, originally covered by tropical semi-deciduous Atlantic Forest in Southeast Brazil. Nutrient relations of four tree species occurring in both planting mixtures were compared between a legume-dominated, species-poor direct seeding mixture of early-successional species ("legume mixture"), and a species-diverse, legume-poor mixture of all successional groups ("diverse mixture"). After 7 years, the legume mixture had 6-fold higher abundance of N(2)-fixing trees, 177% higher total tree basal area, 22% lower litter C/N, six-fold higher in situ soil resin-nitrate, and 40% lower in situ soil resin-P, compared to the diverse mixture. In the legume mixture, non-N(2)-fixing legume Schizolobium parahyba (Fabaceae-Caesalpinioideae) had significantly lower proportional N resorption, and both naturally regenerating non-legume trees had significantly higher leaf N concentrations, and higher proportional P resorption, than in the diverse mixture. This demonstrate forms of plastic adjustment in all three non-N(2)-fixing species to diverged nutrient relations between mixtures. By contrast, leaf nutrient relations in N(2)-fixing Enterolobium contortisiliquum (Fabaceae-Mimosoideae) did not respond to planting mixtures. Rapid N accumulation in the legume mixture caused excess soil nitrification over nitrate immobilization and tighter P recycling compared with the diverse mixture. The legume mixture succeeded in accelerating tree growth and canopy closure, but may imply periods of N losses and possibly P limitation. Incorporation of species with efficient nitrate uptake and P mobilization from resistant soil pools offers potential to optimize these tradeoffs.

Aspectos sensoriais e físico-químicos de “iogurtes” de soja com espessantes/estabilizantes a base de fécula de inhame (Dioscorea alata), amido modificado e gelatina

This study had as objective to evaluate the effect of yam starch, modified starch from Cargill-Brasil (Amidomax 4800 (R)) and gelatin from Gelita-Brasil (GEL-LAC) as stabilizers/thickeners in different ratios and combinations in the soy yoghurt fermented with Enterococcus faecium and Lactobacillus helveticus ssp jugurti. Ten soy yoghurt formulations containing these different stabilizers/thickeners, always totalizing 0.5% in relation to the final formulation, were analyzed in sensorial and physical-chemical terms. Based on the observed results, it was concluded in relation to the sensorial point of view that the more appropriate product was processed only with gelatin at 0.5% concentration. This product also presented the best physical-chemical results related to consistency, syneresis and water holding capacity. However, the isolated use of gelatin increased fermentation time of the soy yoghurt.

Relações entre mídia e lazer:o capitalismo, os meios e a apropriação do tempo livre nas sociedades industrial e pós-industrial

This research aims to understand the relationship between media, capitalism and ownership of free time for leisure practices in industrial societies and postindustrial. Searching is thus a conceptual framework that takes into account the kind of ideology that naturalizes the relationship of leisure with the foundations of contemporary media, and the media only with leisure, forgetting their insertion in the labor and industrial relations in society. We intend to demonstrate that every mode of production, in the capitalist system, entails a mode of reproduction. Methodologically, this is a first approximation, from theoretical concerns already performed, constituting a theoretical research, bibliographic and descriptive character. The results of the text drives us to the conclusion that the work and leisure spheres tend to be less and less differentiated, since both remain as activities of product management with the same intellective protocols, based on information and communication technology, and that accordingly, the media favors an expansion of productive activity even during leisure time
