Morte na antilírica de João Cabral de Melo Neto

The critic João Alexandre Barbosa, points in the work Agrestes (1981-1985), of the Brazilian poet João Cabral de Melo Neto, the presence of individualized death. Thus way, this study proposes to analyse the meanings of lyrism and first-person enunciations, in the work Agrestes, a trace gradually eliminated from Cabral’s discursive field since his first work, Pedra do Sono (1940-1). These elements will clash with João Cabral’s poetics, previously based on the selection of voices and artistic practices consistent with his compositional method, with rigorous sorting values and elimination of any subjectivism. To understand this inconsistency, we propose studying the last part of the work Agrestes, entitled “A indesejada das gentes”, a place where the theme of death is recurrent, as well as the presence of enunciators to set out, even to reveal its feelings about aging and death. The analytical procedure should research the hypothesis of rupture of the inflexible tone of João Cabral’s speech that would follow in respect to the poetic project, a reverse path, starting from objective poetry in the direction of subjective poetry.

Revisitações homoeróticas e sensibilidades pós-modernas na ficção de Guilherme de Melo

The aim of this essay is to offer a new angle on the novel A sombra dos dias [The shadow of the days] by Guilherme de Melo, published in 1981, stressing the homoerotic look on Mozambique's Colonial War and the Lourenço Marques society of the time, recreated her in another direction, revealing the scenarios and the behavior of that society. We propose a rereading of a not too distant past, which still has political and cultural effects on Portuguese society.

Influência do cimento obturador e agente de irrigação final na infiltração marginal em situações de sobreobturações endodônticas

Objective: The objective of this paper was to verify if the final irrigation at 17% EDTA, separately or followed by chlorhexidine digluconate at 2% interferes on the apical marginal leakage in root canal overfilling, due to the use of two root canal filling materials (Sealer 26TM or SealapexTM). Methods: Forty lower incisors extracted, with a single root canal, were biomechanically prepared, at 2.0mm beyond the radicular apex, with ProTaper SystemTM, finishing it with the F3 instrument. Irrigation was accomplished with 1.0 mL NaOCl at 2.5% at each change of equipment caliper and, in the end, with 5.0 mL normal saline solution. After achieving this procedure, the foraminal channels was standardized with a file K 25 until its DO appears in the foraminal opening. From this moment, the teeth were subdivided into two groups of 20 specimens each, because of the final irrigation method used: I – irrigation with EDTA at 17% for 3min and II – identical protocol, thus, after EDTA aspiration at17%, it was again irrigated with chlorhexidine digluconate at 2%, also kept intra-canal for 3min. Each group was again sub-divided into two sub-groups (ten teeth each), according to the cement used (Sealer 26TM or SealapexTM), and filled by using a single gutta-percha F1 (ProTaperTM, Universal Filling), in such a manner that it goes 2.0 mm beyond the radicular apex. Soon after that, the teeth were immersed in Rhodamine BTM for 72h, vacuum and after the roots have been bucolingually grooved, the leakages marked were measured with program Image ToolTM. Results and Conclusions: The leakage magnitude was similar among themselves (p > 0.05), except for group Sealapex®, thus the final use with chlorhexidine reduced apical leakage (p < 0.05).

Influência da agulha irrigadora e da dilatação do canal radicular na eficácia da irrigação endodôntica

Introduction: The irrigation of root canals aims to their cleaning and disinfection, improving endodontic treatment success. Objective: To investigate the influence of the diameter and type of irrigation needle and the root canal enlargement on the mechanical efficacy of endodontic irrigation. Material and methods: Twelve human single-rooted mandibular incisors were used. During some instrumentation stages (enlargement by #20, #30, and #40 K file), root canals were filled with radiographic contrast solution mixed to propyleneglycol and zinc oxide. Needles with different diameters and designs were employed: G1 – 23G and lateral opening; G2 – 22G and apical opening; G3 – 30G and lateral opening; G4 – 30G and apical opening. The needles were inserted up to resistance, with 1 mm step-back to avoid root canal obliteration. The irrigation was performed with 2 mL of distilled water. Before and after irrigation/aspiration, teeth were radiographed at bucco-lingual and mesiodistal direction, using a digital radiographic system. Then, root canal areas, before (filled by contrast solution) and after irrigation (remnant of contrast solution), were submitted to image subtraction with Adobe Photoshop CS4 software. Subsequently, the areas were measured by Image Tool 3.0 software, allowing the obtaining of the cleaning percentage for each modality. Data were analysed by using Anova and Tukey’s test. The level of significance was set at P < 0.05. Results: For all root canal enlargements, 30G needles (G3 e G4) presented a better cleaning efficacy. In all groups, higher cleaning efficacy percentage was observed at #30 and #40 K file enlargement. Conclusion: Regardless their design, thinner needles were more effective; a better cleaning efficacy occurred in more enlarged root canals.

Desempenho agronômico de cultivares de cevada cervejeira sob diferentes lâminas de irrigação

The research work aimed to evaluate the performance of barley cultivars under different irrigation depths in Brazilian Cerrado. The experiment was conducted in a split plot completely randomized design, with irrigation depths (50, 75, 100 and 125% of crop evapotranspiration) in the plots and barley cultivars (BRS Sampa, BRS Manduri and BRS 195) in the split-plots, with four replications. Barley cultivars were different regarding number of tillers per plant, number of spikelets per spike, and root depth. The maximum yields for BRS Sampa, BRS Manduri and BRS 195 were 5,848; 5,449; and 4,767 kg ha(-1), respectively. BRS Sampa showed a value 17% higher than the yield reported by the holder. The irrigation depth affected all the agronomic traits. It is recommended BRS Sampa for Brazilian Cerrado, that didn't differ from other cultivars and was developed in region of similar climate; with replacement of 100% of crop evapotranspiration.

Resistência de porta-enxertos de cucurbitáceas a nematóides e compatibilidade da enxertia em melão

Nematodes severely attack net melon plants under protected cultivation conditions. The objective of this research was to select rootstocks with resistance to Meloidogyne incognita and M. javanica. The experiment was carried out under greenhouse conditions from October 2010 to April 2011 in Jaboticabal, Sao Paulo state, Brazil. Thirty-three cucurbitaceous genotypes were investigated as rootstocks; melons: CNPH 01-930 (Cucumis melo var. flexuosus), CNPH 01-962, 01-963 CNPH (Cucumis melo var. conomon), cvs. Gaucho Redondo, Gaucho Comprido, Redondo Amarelo, Gulfcoast, Chilton, Bonus no. 2, Fantasy; watermelons: cv. Charleston Gray, Progenie da Coreia (Citrullus lanatus); pumpkins: cvs. Mra. Ma, Ornamental, Howden, Mammoth, Kururu, Goianinha (Cucurbita moschata); gourd: Abobora de Porco, cvs. Maranhao, Brasileirinha (Lagenaria siceraria); squash: cv. Pataca Gigante (Cucurbita maxima); cucumber: cvs. Caipira, Branco Meio Comprido, Curumim (Cucumis sativus); loofah: Metro, Semente Branca, Semente Preta (Luffa cylindrica); wax gourd (Benincasa hispida); pumpkin rootstock: Hybrid cv. Keij; snake gourd (Trichosanthes cucumerins) and musk cucumber (Sicana odorifera). To evaluate the resistance, seedlings were transplanted to pots and the root inoculated with 3,000 eggs and second stage juveniles of M. incognita and M. javanica. Fifty days after the inoculation, the plants were evaluated for nematode resistance by means of the reproduction factor. The grafting compatibility between net melon cvs. Bonus no. 2 and Fantasy and the rootstocks previously characterized as resistant were evaluated by means of 60 graftings. CNPH 01-962, CNPH 01-963 and melon 'Gaucho Redondo', were considered resistant to M. incognita. Melon 'Redondo Amarelo', watermelon 'Charleston Gray', watermelon Progenie da Coreia, Trichosanthes cucumerins were considered resistant to M. javanica. Benincasa hispida was resistant to M. javanica and M. incognita. The compatibility between net melons and resistant rootstocks was higher than 98%.
