La Posada en escena d'òpera en la didàctica de l'expressió musical

Proposem en aquest article una metodologia concreta per a l'anàlisi d'una òpera i la seva posada en escena, amb la intenció de formar l'espectador en el reconeixement de la veritat artística i la bellesa que aquesta comporta. Mitjançant l'estudi d'aquesta metodologia s'observa com l'expressió musical en la dramatúrgia de l'obra, manifestació de la veritat de l'obra i per tant del compositor, és l'eix central de la seva posada en escena i de la realització de l'òpera com a obra artística

La Seu, Promotora urbanística: les escales de la Pera

Les escales de la Pera i la plaça dels Apòstols són un conjunt pensat i dut a terme de manera unitària pel capítol de la catedral a inicis del segle XVI, i com a tal constitueixen l'espai renaixentista més rellevant de la ciutat. Una obra important no tant des del punt de vista estètic, com perquè va suposar alhora un rellevant treball d'enginyeria hidràulica de costosa execució. Aquest treball, tot aplegant el material existent sobre aquesta acció urbanística, intentarà de precisar-ne el context i els precedents, de dibuixar-ne millor el propòsit, d'aclarir-ne alguns altres aspectes mitjançant l'aportació de noves dades documentals i, sobretot, de posar de relleu aquesta condició de gran obra cinccentista

Utopía e imágenes marinas en el cine Brasileño: Papel fundamental de Glauber Rocha

Gracias a su riqueza y complejidad, las imágenes marítimas de Rocha se convirtieron en la fuente principal de los motivos utópicos disponibles en el cine brasileño. En particular, “El Cinema de Retomada” de mediados de los años noventa trajo mitos inaugurales y los impulsos vinculados a la formación de Brasil y la identidad nacional, favoreciendo el retorno del pensamiento utópico. Terra em Transe ofrece un punto de partida para la trayectoria utópica más reciente. Representaría el oscuro período de gobierno del presidente Collor, cuando la transición a la democracia parecía condenada al fracaso, Brasil se había convertido en una nación de emigrantes, y el mar, que un día fue cruzado por los descubridores portugueses, llevó a los personajes hacia la derrota y la muerte, en lugar del paraíso esperado. Desde ese momento, impulsada por un giro económico favorable en el país, la curva se eleva, proporcionando una lectura más positiva de las imágenes del sertón del Cine Nuevo. Películas como Corisco y Dada (Rosemberg Cariry, 1996), Baile perfumado, (Lírio Ferreira y Paulo Caldas, 1997) y Crede-mi (Bia Lessa y Dany Roland, 1997) muestran un sertón colorido junto al mar e imágenes marinas, evidenciando la posibilidad, o incluso la realización del paraíso prometido. Muchas otras películas de los noventa presentaron imágenes del mar y extensiones de agua, ya sea en sus escenas de apertura o en momentos claves en los que adquieren un significado totalmente alegórico. Por ejemplo O Sertão das memorias (José Araújo, 1996), Bocage, o triunfo do amor (Djalma Limongi Batista, 1998), Ação entre amigos (Betro Brant, 1998), Terra do mar (Eduardo Caron y Mirella Martinelli, 1998) y Hans Staden (Luiz Alberto Pereira, 1999). La lista en sí, de ninguna manera exhaustiva, da fe de la importancia del tropo marítimo en el reciente cine brasileño y al rol inaugural de Rocha en la formación de la imaginación cinematográfica de Brasil.

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

Adubos foliares quelatizados e sais na absorção de boro, manganês e zinco em laranjeira Pera

O presente trabalho teve como objetivo comparar a eficiência de formulações de adubos foliares quelatizados na absorção dos micronutrientes boro, manganês e zinco, com a aplicação convencional de sais em plantas de laranjeira Pera (Citrus sinensis (L.) Osbeck). Para tanto foi conduzido experimento nas dependências do Departamento de Ciência do Solo da Faculdade de Ciências Agronômicas UNESP/Campus de Botucatu, Estado de São Paulo. Utilizaram-se plantas de laranjeira Pera (Citrus sinensis (L.) Osbeck) enxertadas sobre limoeiro Cravo (Citrus limonia Osbeck), com 2 anos de idade, plantadas em caixas de 250 litros. Os adubos foliares utilizados foram: Grex Citros na dose de 1,0 mL L-1; Copas citros 2,0 mL L-1; Plantin Citros 1,0 mL L-1; Citrolino 2,0 mL L-1; Fertamin Citros 1,75 mL L-1; Yogen Citros 2,0 mL L-1; MS-2 1,0 mL L-1; Sais, Sais + 1,0 g L-1 de KCl e Sais substituindo o ZnSO4 pelo ZnCl2. O volume de aplicação, foi de 1 litro de calda planta-1. em todos os tratamentos adicionou-se o espalhante adesivo do grupo químico dos alquifenoletoxilados a 0,03%. A amostragem das folhas foi realizada 30 dias após a aplicação dos tratamentos, coletando-se a 3a ou 4a folha de ramos vegetativos no início do florescimento, dos 4 quadrantes, localizados na região mediana da planta, totalizando 10 folhas por planta. A aplicação foliar de micronutrientes, favoreceu a absorção e resultou no aumento do teor foliar de Mn e Zn mas não de B, sendo que a presença de cloreto aumentou os teores de Zn na folhas de laranjeira Pera , proporcionando maior absorção do que o sulfato e sulfato adicionado ao cloreto de potássio. Os resultados mostram, também, que os produtos quelatizados Yogen e MS-2, para as condições deste estudo, não foram eficientes como fontes fornecedoras de Mn.

Remoção de frações de óleo leve e pesado de rocha calcária através de sistemas microemulsionados

In this research the removal of light and heavy oil from disintegrated limestone was investigated with use of microemulsions. These chemical systems were composed by surfactant, cosurfactant, oil phase and aqueous phase. In the studied systems, three points in the water -rich microemulsion region of the phase diagrams were used in oil removal experiments. These microemulsion systems were characterized to evaluate the influence of particle size, surface tension, density and viscosity in micellar stability and to understand how the physical properties can influence the oil recovery process. The limestone rock sample was characterized by thermogravimetry, BET area, scanning electron microscopy and X-ray fluorescence. After preparation, the rock was placed in contact with light and heavy oil solutions to allow oil adsorption. The removal tests were performed to evaluate the influence of contact time (1 minute, 30 minutes, 60 minutes and 120 minutes), the concentration of active matter (20, 30 and 40 %), different cosurfactants and different oil phases. For the heavy oil, the best result was on SME 1, with 20 % of active matter, 1 minute of contact time, with efficiency of 93,33 %. For the light oil, also the SME 1, with 20 % of active matter, 120 minutes of contact time, with 62,38 % of efficiency. From the obtained results, it was possible to conclude that microemulsions can be considered as efficient chemical systems for oil removal from limestone formations

Gas exchange rates at different vapor pressure deficits and water relations of 'Pera' sweet orange plants with citrus variegated chlorosis (CVC)

Net photosynthesis (A) and transpiration rates (E), stomatal conductance (g), water use efficiency (WUE), intrinsic water use efficiency (IWUE) and internal leaf CO2 concentration (C) in response to different vapor pressure deficit (1.2 and 2.5 kPa) were investigated in 'Pera' sweet orange plants affected by citrus variegated chlorosis (CVC), a disease caused by Xylella fastidiosa. All plants were well watered and leaf water potential (Pw) was also measured by the psychrometric technique. Results showed that healthy plants responded to higher vapor pressure deficit (VPD), lowering its net photosynthesis and transpiration rates, and stomatal conductance. However, diseased plants presented no clear response to VPD, showing lower A, E and g for both VPDs studied and very similar values to these variables in healthy plants at the highest VPD. Internal leaf CO2 concentration also decreased for healthy plants when under the highest VPD, and surprisingly, the same pattern of response was found in plants with CVC. These results, the lower Psi(w) and higher WUE values for diseased plants, indicated that this disease may cause stomatal dysfunction and affect the water resistance through xylem vessels, which ultimately may play some role in photosynthetic metabolism.
