Nitrogen and potassium fertilization of 'Nanicao' banana (Musa AAA Cavendish subgroup) under irrigated and non-irrigated conditions

A field experiment was carried out in São Paulo State, Brazil, with the objective of investigating the response of 'Nanicao' banana (Musa AAA Cavendish subgroup) to nitrogen and potassium fertilization under irrigated and non-irrigated conditions during two crop seasons. The effects of cropping on some soil chemical properties were also investigated. A split-plot design was used with irrigation (micro-sprinkler) and no irrigation applied to main plots, and a combination of four rates of N (0, 200, 400 and 800 kg N ha-1) and K (0, 300, 600 and 900 kg K2O ha-1) as the sub-plot treatments. Irrigation caused a significant increase in fruit yield and determined the response to N and K fertilizers. In spite of a high level of exchangeable K, a positive response to K application was observed on the plant crop in non-irrigated plants. Fruit yield was impaired by N application in the plant crop (1st cycle). A positive response to N application was observed in the 2nd cycle. Soil pH decreased with increasing N rates. Exchangeable K was significantly reduced due to crop exhaustion.

Partilha de néctar de Musa paradisiaca (Musaceae) por três espécies de morcegos filostomideos na região Sudeste do Brasil

O genero Musa apresenta características em suas inflorescências como: grande tamanho, visibilidade, odor floral e fluxo de néctar abundante, que tornam o gênero um importante recurso para morcegos fitófagos. O objetivo do presente trabalho foi estudar as interações entre morcegos filostomideos e flores de M. paradisiaca no pomar da fazenda Santo Antônio dos Ipês, Município de Jaú, São Paulo. Três espécies (Glossophaga soricina, Anoura caudifer e Phyllostomus discolor) foram observadas alimentando-se do néctar das flores das bananeiras do pomar. Três formas distintas de comportamento de visita foram observadas: “adejo” para G. soricina e A. caudifer, “pouso de frente na inflorescência” para G. soricina e “pouso de cabeça para baixo na inflorescência” para P. discolor. As visitas ocorreram durante toda noite (das 18h00 às 6h00), com pico de vistas das 20h00 à 1h00. As visitas entre duas sub-famílias ocorriam de forma alternada nestes horários. Apesar das três espécies de filostomideos partilharem o néctar das bananeiras, os glossofagineos são os principais beneficiados por esse recurso alimentar, uma vez que cerca de 88% (N=694) das visitas registradas às suas flores foram realizadas por G. soricina e A. caudifer, enquanto apenas 12% (N=97) foram por P. discolor

Dilemas na tradução de Muse & Drudge (Musa E Mula), de Harryette Mullen: negritude, dissonância e miscigenação

This paper aims to discuss a project of translating part of the work Muse & Drudge, by the award-winning African-American poet Harryette Mullen, into Brazilian Portuguese, with focus on a single poem. In Muse & Drudge Mullen combines cultural critique with humor, lyricism and punning, which has unfolded the frontiers between cultural and racial identity, and has put into question the opposition between popular and high culture. This work analyzes to which extent the proposed translation produces a new set of intertextual relations that might culminate in “unexpected” meanings. It is a goal to understand how the effects of such “unexpected” meanings reveal the “encounter” between the so-called racial “black/white” dichotomy, predominant in the US culture, and the notion of “miscegenation” and “racial democracy” in Brazil.

O poético alinhave de Murilo Mendes: o poeta, a musa e a metapoesia em As Metamorfoses

Lying under the contribution of a display of characteristics with multiple meanings (Catholicism, Surrealism, unite of contraries, and the dialogue with other types of art), Murilo Mendes focalizes some subjects that are made to become appealing in his works. Some of these subjects appear in his 1945’s poetry book, As metamorfoses, the object of analysis in this present work: the poet’s figure, insert in the historical view of the World War II and by the poet devastated; the muse’s figure, carrier of the sacred and the profane, whose body represents a repository of descriptions with surrealistic meanings, that is shown indistinctly as the poetry itself; and, concluding, the poetry (or the metapoetry) expressed in this context (historical and literary). Therefore, we intend to search, based in the analysis of poems, how each of this instances are configured inside the poetic universe of Murilo Mendes, with the intention of enlighten the constitution of the sewing made of them by the poet from Juiz de Fora; instances that are very precious when we deal with the poetry that gives to his writings the patent feature of modernity.

Romantismo brasileiro e a 'musa popular do Norte'

Bajo la influencia alemana, el culto a las tradiciones populares como una forma de valorización del pueblo, o sea, la exaltación nacionalista o humanitaria del pasado fue uno de los rasgos marcantes del romanticismo. Más allá de concordar con la valorización de los origenes de la nacionalidad, Franklin Távora se empeñará en profundizar el espíritu cientí- fico de sus investigaciones acerca del folclore, como vemos en “Lendas e tradições populares do Norte”, publicadas en la Ilustração Brasileira en 1877.

Condyloma acuminata in the tongue and palate of a sexually abused child: a case report

Condyloma acuminata caused by human papilloma viruses, (HPV) is a sexually transmitted disease (STD) appearing most frequently as soft, pink cauliflower like growths in moist areas, such as the genitalia, mouth and other places. The disease is highly contagious, can appear singly or in groups, small or large. In children, the isolation of a sexually transmitted organism may be the first indication that an abuse has occurred. Although the presence of a sexually transmissible agent from a child beyond the neonatal period is suggestive of sexual abuse, exceptions do exist. The authors report the clinical case of a five-year-old Caucasian male with lesions located in the dorsal surfaces of the posterior tongue and palate. Both lesions had a firm consistency, reddish appearance and presence of whitish areas and regions of ulceration. During the interview, the mother reported that the boy had been sexually abused. Sexually transmitted disease may occur during sexual abuse. Dentists as well as pediatricians have a role to play in identifying and treating these children. The diagnosis is essentially clinical (anamnesis and physical examination), but also the use of cytology eventually resorts to biopsy of the suspicious lesions for histological examination. The therapeutic option was the excision of the lesions.

Leishmanicidal activity in vitro of Musa paradisiaca L. and Spondias mombin L. fractions

Visceral leishmaniasis (VL) is a zoonotic disease characterized by infection of mononuclear phagocytes by Leishmania chagasi. The primary vector is Lutzomyia longipalpis and the dog is the main domestic reservoir. The control and current treatment of dogs using synthetic drugs have not shown effectiveness in reducing the incidence of disease in man. In attempt to find new compounds with leishmanicidal action, plant secondary metabolites have been studied in search of treatments of VL. This study aimed to evaluate the leishmanicidal activity of Musa paradisiaca (banana tree) and Spondias mombin (cajazeira) chemical constituents on promastigotes and amastigotes of L. chagasi. Phytochemical analysis by column chromatography was performed on ethanol extracts of two plants and fractions were isolated. Thin layer chromatography was used to compare the fractions and for isolation the substances to be used in vitro tests. The in vitro tests on promastigotes of L chagasi used the MTT colorimetric method and the method of ELISA in situ was used against amastigotes besides the cytotoxicity in RAW 264.7 cells. Of the eight fractions tested, Sm1 and Sm2 from S. mombin had no action against promastigotes, but had good activity against amastigotes. The fractions Mp1 e Mp4 of M. paradisiaca were very cytotoxic to RAW 264.7 cells. The best result was obtained with the fraction Sm3 from S. mombin with IC50 of 11.26 mu g/ml against promastigotes and amastigotes of 0.27 mu g/ml. The fraction Sm3 characterized as tannic acid showed the best results against both forms of Leishmania being a good candidate for evaluation in in vivo tests. (C) 2012 Published by Elsevier B.V.

Isolation and characterization of the flour and starch of plantain bananas (Musa paradisiaca)

Plantain bananas of the variety Terra (Musa paradisiaca) may have industrial value due to their high starch content. In this research, the flour and starch of such unripe fruit were isolated and their chemical, physicochemical, and structural characteristics were determined. Banana flour and starch had a dry basis yield of 50.6 and 28.5%, and an average granule size of 31.7 and 47.3?mu m, respectively. Both raw materials revealed a C-type pattern and high gelatinization temperatures. The peak viscosity was greater for flour (378.0 RVU) than for starch (252.6 RVU), although the final viscosity was lower. At temperatures above 65 degrees C, the swelling power of banana flour was lower than that of starch, while the solubility of flour was greater than that of starch at all temperatures. Furthermore, the presence of other components in banana flour influenced its physicochemical properties. In general, the flour and starch processed from unripe bananas have numerous possible uses as ingredients in food systems and for other industrial purposes.

La musa bambina. 1911-2011: un secolo di letteratura mitologica per ragazzi in Italia tra storia, educazione e narrazione

Questa ricerca mostra l’evoluzione della letteratura mitologica per ragazzi in Italia. Il primo libro italiano di mitologia per bambini è stato pubblicato nel 1911 (lo stesso anno di un’importante e violenta guerra coloniale tra l’Italia e la Libia): la scrittrice italiana Laura Orvieto pubblicò allora “Storie della storia del mondo”, in cui riunì antichi racconti greci per giovani lettori. Queste storie erano ispirate al libro mitologico per bambini “Il libro delle meraviglie” di Hawthorne (titolo originale “A Wonder Book for Girls and Boys”). In seguito molti scrittori italiani scrissero libri mitologici per giovani lettori: serie importanti di libri di mitologia per bambini furono pubblicate durante il regime mussoliniano – talvolta per diffondere l’ideologia fascista della superiorità romana. Durante questo periodo, i libri mitologici spesso mostravano uno stile letterario solenne. Dopo la seconda guerra mondiale, la letteratura mitologica per bambini cambiò lentamente prospettiva: gli scrittori italiani cominciarono ad usare il mito per parlare di problemi sociali (p.e. Gianni Rodari descriveva re Mida come un capitalista) e per spiegare le diverse condizioni umane (p.e. Beatrice Masini fa riferimento alle dee e alle eroine greche per descrivere la condizione femminile). La ricerca analizza anche la relazione tra mito e scuola in Italia: i racconti mitologici hanno sempre fatto parte dei programmi scolastici italiani per bambini dagli 8 agli 11 anni. Le riforme scolastiche – deliberate negli anni ’20 e ’40 – fissarono pratiche didattiche sui miti ancora oggi in uso. I racconti mitologici erano soprattutto un supporto per gli studi storici e letterari. Tuttavia, negli ultimi decenni, i miti sono divenuti un importante aiuto per gli insegnamenti scientifici e artistici.
