Ópera e literatura em cena: uma análise da obra juvenil aída, adaptada por han mi-ho e ilustrada por Lucia Sforza

This text’s objective is to present an analysis of Aída, adapted by Han Mi-Ho (2012) and illustrated by Lucia Sforza, from the classic eponymous opera by Giuseppe Verdi. This book is part of the collection Classical music on the scene, published by FTD, which aims to introduce stories of important librettos regarded as classics in the music field to young audiences. More specifically, we intend to verify in this text, with Bakhtinian principles, how the dialogue between Verdi’s work and HanMi-Ho’s is actualized. To achieve these objectives, we will present a reflection of what provides the pleasure in reading. In this text we built the hypothesis that Han-Mi-Ho’s strategy to rescue a classic opera and adapt it in the form of an illustrated narrative for the young reader provides the contact with an attractive and playful text that leads to critical reflection and expands his knowledge through the rescue of the cultural memory. The appropriation of a classic cultural production adapted to the narrative language and targeted to a young audience can act as an appraisal factor in the identity of the reader. Through it, he is able to raise his self-esteem, because he perceives that he is considered as a production receiver, while at the same time he is recognized as the heir of a traditional cultural heritage.

Low variation in ribosomal DNA and internal transcribed spacers of the symbiotic fungi of leaf-cutting ants (Attini: Formicidae)

Leaf-cutting ants of the genera Atta and Acromyrmex (tribe Attini) are symbiotic with basidiomycete fungi of the genus Leucoagaricus (tribe Leucocoprineae), which they cultivate on vegetable matter inside their nests. We determined the variation of the 28S, 18S, and 5.8S ribosomal DNA (rDNA) gene loci and the rapidly evolving internal transcribed spacers 1 and 2 (ITS1 and ITS2) of 15 sympatric and allopatric fungi associated with colonies of 11 species of leafcutter ants living up to 2,600 km apart in Brazil. We found that the fungal rDNA and ITS sequences from different species of ants were identical (or nearly identical) to each other, whereas 10 GenBank Leucoagaricus species showed higher ITS variation. Our findings suggest that Atta and Acromyrmex leafcutters living in geographic sites that are very distant from each other cultivate a single fungal species made up of closely related lineages of Leucoagaricus gongylophorus. We discuss the strikingly high similarity in the ITS1 and ITS2 regions of the Atta and Acromyrmex symbiotic L. gongylophorus studied by us, in contrast to the lower similarity displayed by their non-symbiotic counterparts. We suggest that the similarity of our L. gongylophorus isolates is an indication of the recent association of the fungus with these ants, and propose that both the intense lateral transmission of fungal material within leafcutter nests and the selection of more adapted fungal strains are involved in the homogenization of the symbiotic fungal stock.

Emergência de plantas daninhas em lavouras de feijão e de trigo após o cultivo de espécies de cobertura de solo

O objetivo do trabalho foi avaliar a emergência das espécies de plantas daninhas Euphorbia heterophylla e Bidens pilosa em áreas de produção de feijão e de trigo, após o cultivo de plantas de cobertura. O trabalho foi conduzido em área sob sistema de plantio direto na palha, manejado por cinco anos consecutivos, na Fazenda Capivara, da Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Arroz e Feijão, localizada no município de Santo Antônio de Goiás, GO. O solo do local é classificado como Latossolo Vermelho distrófico. Os tratamentos foram constituídos pela combinação de sete plantas de cobertura de solo: braquiarão (Brachiaria brizantha) - cv. Marandu; braquiarão em consórcio com o milho (Zea mays) - híbrido HT BRS 3150; guandu-anão (Cajanus cajan); milheto (Pennisetum glaucum) - cv. BN-2; mombaça (Panicum maximum) cv. Mombaça; sorgo granífero (Sorghum bicolor) - cv. BR 304; e estilosantes (Stylosanthes guianensis) - cv. Mineirão e por duas culturas cultivadas em sucessão nas áreas: feijão cv. Pérola e trigo - Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) 42. Todas as plantas de cobertura foram cortadas no mesmo dia, utilizando-se um triturador de palhada, e deixadas na superfície do solo. As semeaduras do feijão e do trigo foram realizadas sessenta dias após o corte das culturas de cobertura. Foram realizadas duas contagens do número de plantas emergidas de E. heterophylla e de B. pilosa, separadas em três estágios de crescimento (plantas com menos de duas folhas, de duas a quatro folhas e com mais de quatro folhas). Entre as plantas de cobertura testadas, braquiarão e mombaça se mostraram as mais promissoras em reduzir a emergência de plantas daninhas em cultivos subseqüentes, apresentando resultados significativos na diminuição do número de plantas de E. heterophylla estabelecidas nas áreas cultivadas com feijão ou com trigo. Não se constataram diferenças quanto à capacidade das culturas de feijão e de trigo em reduzir a população de E. heterophylla e B. pilosa.

Temporal variability of soil CO2 emission after conventional and reduced tillage described by an exponential decay in time model

A quantificação do impacto das práticas de preparo sobre as perdas de carbono do solo é dependente da habilidade de se descrever a variabilidade temporal da emissão de CO2 do solo após preparo. Tem sido sugerido que as grandes quantidades de CO2 emitido após o preparo do solo podem servir como um indicador das modificações nos estoques de carbono do solo em longo termo. Neste trabalho é apresentado um modelo de duas partes baseado na temperatura e na umidade do solo e que inclui um termo exponencial decrescente do tempo que é eficiente no ajuste das emissões intermediárias após preparo: arado de disco seguido de uma passagem com a grade niveladora (convencional) e escarificador de arrasto seguido da passagem com rolo destorroador (reduzido). As emissões após o preparo do solo são descritas utilizando-se estimativa não linear com um coeficiente de determinação (R²) tão alto quanto 0.98 após preparo reduzido. Os resultados indicam que nas previsões da emissão de CO2 após o preparo do solo é importante considerar um termo exponencial decrescente no tempo após preparo.

Metastatic intraocular chondrosarcoma in a dog

Chondrosarcoma accounts for about 10% of all canine bone tumors and is the second most common primary bone tumor in dogs. In veterinary medicine, chondrosarcomas are classified as skeletal and extraskeletal. Extraskeletal chondrosarcomas are mesenchymal neoplasms of soft tissues and visceral organs that produce neoplastic chondrocytes in a fibrillary matrix. There is no involvement of bone or periosteal tissues in extraskeletal chondrosarcomas. The aim of this report is to describe the first case of a metastatic intraocular extraskeletal chondrosarcoma in a dog.

Effects of nitrous oxide on IOP and pupillary diameter in dogs anesthetized with varying concentrations of desflurane

Objective The aim of the present study was to evaluate the effects of nitrous oxide on TOP and pupillary diameter (PD) of dogs anesthetized with varying desflurane concentrations.Animals studied Twenty adult Mongrel dogs were used.Methods They were anesthetized with propofol (10 mg/kg, IV) and maintained with varying concentrations of desflurane (1.6, 1.4, and 1.2 MAC diluted in 100% oxygen (G1) or in 70% nitrous oxide and 30% oxygen (G2) (30 mL/kg/min). TOP was measured by applanation tonometry and horizontal PD was taken with a caliper adjacent to the cornea. Mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), and end-tidal CO, (etCO(2)) were also measured. All parameters were measured at TO, T30, T45, and T60 time points. One-way repeated measures ANOVA and the t-test were used to assess statistical differences (P < 0.05).Results T30, T45, and T60 TOP measures were Within normal limits for both groups and TOP did not differ between groups at any time. There was a significant decrease in PD in G I between TO and T30, T45 and T60, and also between T30 and T60. PD did not differ between groups. All vital parameters were within normal limits throughout anesthesia.Conclusions Administration of nitrous oxide with desflurane results in maintenance of normal TOP and prevents a decrease in horizontal PD during anesthesia. Therefore, this may be a suitable protocol in dogs undergoing intraocular surgeries that require mydriasis and maintenance of normal TOP.

Controle químico de plantas dos gêneros Ipomoeae Merremia em cana-soca

To evaluate the efficiency of herbicide application in post emergence, alone and in mixture, for Ipomoea grandifolia, I. hederifolia, I. purpurea, I. quamoclit, Merremia aegyptia and M. cissoides control in sugarcane, an experiment was conducted on a commercial production area in Jaboticabal, SP, Brazil, from November 2007 to July 2008. Six herbicide treatments [trifloxysulfuron plus ametryn (37 plus 1463.07 g ha(-1)), diuron plus hexazinone (1.170 + 330 g ha(-1)), metribuzin (1.920 g ha(-1)), (trifloxysulfuron plus ametryn, 27.75 + 1097.3 g ha(-1)) plus (diuron plus hexazinone, 702 + 198 g ha(-1)), metribuzin (960 g ha(-1)) plus (trifloxysulfuron plus ametryn, 27.75 + 1097.3 g ha(-1)) and metribuzin (960 g ha(-1)) plus (diuron plus hexazinone, 702 + 198 g ha(-1))] and two treatments without application were evaluated. The visual injuries caused by the herbicide did not affect stalk number and stalk diameter in sugarcane. However, the plants treated with diuron plus hexazinone presented lower stalk height. The herbicides diuron plus hexazinone, alone and in mixture with trifloxysulfuron plus ametryn, were efficient in the control of all morningglory and woodrose species. Application of trifloxysulfuron plus ametryn alone controlled satisfactorily only I. hederifolia. Metribuzin was efficient in the control of I. grandifolia, I. quamoclit, M. aegyptia and M. cissoides. Besides these species, the association of this herbicide with diuron plus hexazinone resulted in excellent I. hederifolia control. The mixture of metribuzin with trifloxysulfuron plus ametryn was efficient in controlling I. hederifolia, M. aegyptia and M. cissoides. The new emergence of the morningglory and woodrose species evaluated after herbicide application or manual weed elimination would not harm the mechanized harvest of sugarcane stalks in the next harvest.

Orbital cellulitis associated with Toxocara canis in a dog

Reports of Toxocara canis ocular larva migrans are uncommon in animals, with only a few cases reported. Most reports involve larval migration into the retina and choroid, with parasitic invasion of the orbit reported only in experimental studies. This is the first clinical case of Toxocara canis infection in the retrobulbar region of a 10-year-old, cross-bred male dog presenting with unilateral orbital cellulitis. Ophthalmic signs included protrusion of the nictitating membrane, chemosis, exophthalmos and hypertropia. The parasite was diagnosed by histologic and parasitologic examination of orbital tissues, which were removed during enucleation.
