O herói na interpretação e na recepção crítica de “Grande sertão: veredas”

O presente estudo constitui-se em uma leitura fincada nos moldes estético-recepcionais do romance Grande sertão: veredas, do escritor João Guimarães Rosa (1908-1967). Após um estudo histórico-artístico das categorias de heróis apresentadas no decorrer da história literária universal e analisadas pela crítica, tais como na epopéia (herói épico), no medievo (herói medieval), na tragédia (herói trágico) e no romance (herói romanesco), incluindo a categoria de herói formulada por Georg Lukács: o herói demoníaco, bem como o herói na modernidade (herói moderno), apresentar-se-á um exame diferenciado da figura da persona baseado na tipologia teórico-crítica jaussiana de herói, que, por sua vez, será utilizado para consideração de um estudo interpretativo e de recepção crítica sobre a personagem na obra rosiana, sobretudo a partir de 1956. Dessa forma, demonstrar-se-á que a atualidade do tema é sustentada pelas obras literárias, que se oferecem como objetos de interrogação para o pensamento crítico, renovando os princípios teóricos de cada época. Para tanto, a análise volta-se para o estudo de importantes nomes da crítica literária no Brasil e no exterior, cuja seleção se deu em função da categoria do herói, tais como Manuel Cavalcanti Proença (1958), Mario Vargas Llosa (1966), Antonio Candido (1969), Walnice Nogueira Galvão (1972), Benedito Nunes (1982), Davi Arrigucci Jr (1994), José Antonio Pasta Jr (1999) e Ettore Finazzi-Agrò (2004), com a finalidade de compreender e explicitar a importância da reconstrução do horizonte de expectativa a partir da tríade hermenêutica que permite ao leitor participar da gênese do objeto estético, expandindo seu contexto e significações.

Chemical composition of corn and sorghum grains cultivated in oxisol with different application methods and doses of zinc

A.P. Puga, R.M. Prado, B. Mattiuz, D.W. Vale, and I.M. Fonseca. 2013. Chemical composition of corn and sorghum grains cultivated in Oxisol according to different application methods and doses of zinc. Cien. Inv. Agr. 40(1):97-108. In general, tropical soils present low concentrations of zinc (Zn), and the deficiency of Zn is recognized as a world nutritional problem for cereal production and human beings. Therefore, the main goal of this study was to assess the effects of different methods of Zn application on the quality of corn and sorghum grains grown in Oxisol. Two experiments were set up in the experimental area of UNESP (campus of Jaboticabal, Brazil). The following nine treatments were applied: three doses of Zn by banded application (seed furrows), three doses of Zn by incorporation into soil (0-20 cm depth), foliar application, seed application, and control (no Zn applied). The treatments were arranged in randomized blocks with four replicates. The contents of Zn, carbohydrates and proteins were determined for corn and sorghum grains. Regardless of the method, Zn application promoted higher contents of this micronutrient in corn and sorghum grains. The banded application method of Zn in soil promoted greater contents of total carbohydrates, starch and protein in both cultures. The incorporation of Zn into the soil method provided higher contents of soluble carbohydrates in both corn and sorghum grains.

Gradients in N-cycling attributes along forestry and agricultural land-use systems are indicative of soil capacity for N supply

Indicators of soil quality associated with N-cycling were assessed under different land-use systems (native forest NAT, reforestation with Araucaria angustifolia or Pinus taeda and agricultural use AGR) to appraise the effects on the soil potential for N supply. The soil total N ranged from 2 to 4 g/kg (AGR and NAT, respectively), and the microbial biomass N ranged from 80 to 250 mg/kg, being higher in NAT and A. angustifolia, and lower in P. taeda and AGR sites. Activities of asparaginase (ca. 50200 mg NH4+-N/kg per h), glutaminase (ca. 200800 mg NH4+-N/kg per h) and urease (ca. 80200 mg NH4+-N/kg/h) were also more intense in the NAT and A. angustifolia-reforested soils, indicating greater capacity for N mineralization. The NAT and AGR soils showed the highest and the lowest ammonification rate, respectively (ca. 1 and 0.4 mg NH4+-N/kg per day), but the inverse for nitrification rate (ca. 12 and 26%), indicating a low capacity for N supply, in addition to higher risks of N losses in the AGR soil. A multivariate analysis indicated more similarity between NAT and A. angustifolia-reforested sites, whilst the AGR soil was different and associated with a higher nitrification rate. In general, reforestation with the native species A. angustifolia had less impact than reforestation with the exogenous species P. taeda, considering the soil capacity for N supply. However, AGR use caused more changes, generally decrease in indicators of N-cycling, showing a negative soil management effect on the sustainability of this agroecosystem.

Engorde de pulpo común Octopus vulgaris en jaulas en la comunidad Canaria [Material gráfico] [Recurso electrónico] : efecto de la dieta y la densidad inicial

Octopus vulgaris on-growing in floating cages is a promising activity implemented in Spain at industrial level, with productions of 16-32 tons/year from 1998. Nevertheless, some aspects of the culture system need to be evaluated to warrantee its profitability. In the present work absolute growth rate (AGR, g/day) and mortality (%) under two initial rearing densities, 10 and 17 kg/m3, were compared under two feeding regimes over 15 weeks. One diet was composed by bogue, supplied as ?discarded? species from local fish farms. The other diet was based on a 40-60% discarded bogue-crab Portunus pelagicus. Half of the reared octopuses were PIT-tagged and two sampling points were established along the experimental period. Regardless of dietary treatment, up to the 11th week, growth was 19 and 13 g./day for the low and high rearing density. On the other hand, up to the 11th week mortality was higher in the control diet fed group (30%), reaching 74-84% by the end of the experiment regardless of rearing density and dietary treatment, which could suggest some nutritional imbalance of the tested diets.

Pre-engorde de pulpo común Octopus vulgaris con 3 dietas basadas en descartes de acuicultura en la comunidad Canaria

On-growing of Octopus vulgaris fed different feeds has shown promising results. Nevertheless, since the minimum legal size for octopus fisheries in spain i sin most of experimental ongrowing of this species an average weight over 750-1000kg was utilized with g (and little research has been conducted in order to evaluate the effect of these diets on smaller individuals. The present work evaluates the effect of 3 diets based on bogue, obtained as ?discarded? species from local fish farms, on ingestion and growth of O. vulgaris weighing 400 g. The 1st diet was composed by discarded bogue, the 2nd diet by a 40-60% discarded bogue-crab Portunus pelagicus and the 3rd diet was presented as a moist diet based on discarded bogue. A triplicate of four octopuses per treatments, male:female 1:1, were kept in circular 400 l tanks and fed each diet for 4 weeks. Absolute growth rate (AGR, g./day), standard feeding rate (SFR, %/day) and feed efficiency (FE) were calculated. The addition of crab to the diet increased SFR which underlines different feeding habits when compared with 0.8-1 kg octopuses. Lower growth and higher FE was recorded with the moist diet, probably due to high disintegration of this kind of feed.

Evaluación de 2 sistemas de cultivo en pulpos macho Octopus vulgaris: efecto de la talla inicial y de la dieta

[EN]Octopus vulgaris on-growing in floating cages has shown promising results. Nevertheless, some aspects of the culture system need to be evaluated to warrantee its profitability. In the present work individual and group rearing, in PVC net compartments and floating cages respectively, are compared under two dietary treatments. One diet is composed by bogue, supplied as ?discarded? species from local fish farms, and the other is based on a 40-60% discarded bogue-crab Portunus pelagicus. Besides, the effect of initial size is also evaluated. All octopuses were PIT-tagged and the experiment lasted 2 months. Absolute growth rate (AGR, g./day) and mortality (%) were calculated. Control diet generated higher growth rates and lower mortality which suggests different crab requirements at higher rearing temperatures. High mortality recorded in individual rearing could be related with high initial rearing density and temperatures.

Evaluación de 2 sistemas de cultivo en pulpo común Octopus vulgaris en jaulas en la comunidad Canaria

Octopus vulgaris on-growing in floating cages is a promising activity implemented in Spain at industrial level, with productions of 16-32 tons/year from 1998. Nevertheless, some aspects of the culture system need to be evaluated to warrantee its profitability. In the present study two rearing systems and two dietary treatments were evaluated. Individual and group rearing, in PVC net compartments and floating cages respectively, were compared under two dietary treatments. One diet was composed by bogue, supplied as ?discarded? species from local fish farms, and the other was based on a 40-60% discarded bogue-crab Portunus pelagicus. All octopuses were PIT-tagged and the experiment lasted two months. Animals were sampled once throughout the experimental period and absolute growth rate (AGR, g./day) and mortality (%) were calculated. AGR of group rearing was above 30 g./day, however individual rearing showed 100% survival so biomass increment was higher. On the other hand, males grew more than females regardless of dietary treatment.

The present work evaluates whether the addition of 2 species of crab (Portunus pelagicus and Grapsus grapsus) as attractants (10%) in experimental moist diet based in discarded bogue (Boops boops) may increase ingestion and growth in O. vulgaris. Besides, another diet based on flour, made from discarded bogue and G. grapsus, was tested. Finally, a 40-60% discarded bogue-crab P. pelagicus was provided as a control diet. Four male octopuses, kept The present work evaluates whether the addition of 2 species of crab (Portunus pelagicus and Grapsus grapsus) as attractants (10%) in experimental moist diet based in discarded bogue (Boops boops) may increase ingestion and growth in O. vulgaris. Besides, another diet based on flour, made from discarded bogue and G. grapsus, was tested. Finally, a 40-60% discarded bogue-crab P. pelagicus was provided as a control diet. Four male octopuses, kept in PVC net cages in the same tank, were fed each diet for 8 weeks and several parameters were calculated: absolute growth rate (AGR, g./day), standard feeding rate (SFR, %/day) and feed efficiency (FE). The addition of crab to the diet under the conditions described did not improve ingestion, growth or feed efficiency in this species, while the flour based diet generated negative growth.
