Estética em revolução

The difficulty lies in dealing with the texts of Almada Negreiros focuses on language, search for expression. Saramago, in his texts of various kinds, "Manual of Painting and Calligraphy" and "The world's largest flower," suffers by seeking representative languages. Which one is less difficult, less traumatic, painting or writing? In conclusion, the two are so much paint as painful to write. Compare them to the knife ripping a sheet of paper. Almada entangled in them all as a poet, novelist, painter, designer, playwright. Through them, we sought from "Before You Begin" to "Getting Started", always be in alpha. The text that follows is entitled Aesthetics in Revolution, it may cover the surrounding poetic Alma.

América latina transterritorial: percursos em fronteiras fluidas

Contemporary artists have proposed repositioning of the view as a psicogeographics, routes of drifts, affectives maps, subverting the physical, historical, political and social places in the global mapping. The Chilean artist Eugenio Dittborn with their "Airmail Paintings" that design, sewing, painting and collage are folded and placed in an envelope and sent by post. At your destination, the paint is removed from the envelope, unfolded and hung leaving the marks of the route traveled. The Argentine artist Alicia Herrero in his work "The trip Revoluvionário - title inspired by the trip that Ernesto Guevara held in South America, traveled by navigable rivers of South America and composed the work in the form of a" novel navigated "where each chapter is a port route. As the river of Heraclitus, the writing of "novel navigated" composes processes transposing borders.

Mona Lisa: sentidos múltiplos de um sorriso enigmático

This article reviews the history of the famous painting by Leonardo da Vinci, the Mona Lisa or Gioconda, sixteenth century, aiming to discuss about some of the multiple senses (or discourses) around its meaning, with the support of the French branch of the Discourse Analysis, especially based on concepts developed by D. Maingueneau. As it is characteristic of the work of art, the senses are open, which does not exclude the possibility of detachment, among which we accentuated the "Mona Lisa smile" as one of the main traits of the authorship by Leonardo Da Vinci and, simultaneously, a trait propitious to aphorisation. Thus, the work of art is releasing of the exclusive authorship of Da Vinci and it suscitates several rereadings, which help composing a discursive ethos around this consecrated painting and, at the same time, which make circulating distinct stereotypes.

Determinação de sacarose no xarope artificial de groselha por medidas de viscosidade: uma abordagem interdisciplinar

The development of the National Curriculum Parameters for High School (PCN) is established from a logic in which the disciplines are integrated and coordinated in order to promote interdisciplinarity. However, there are few didactic-pedagogic activities that enable teachers in practice to reach this goal. In this paper, we propose an experimental activity to be used with High School students, addressing the concept of viscosity from an interdisciplinary perspective between the disciplines of Physics and Chemistry. For that purpose, flow times of sucrose solutions of different concentrations will be measured in a glass Ford and these data will be used to construct a calibration curve, which will be used to determine the concentration of sucrose in artificial flavor syrup of gooseberry.

A retrospective look at esthetic resin composite and glass-ionomer Class III restorations: A 2-year clinical evaluation

Objective: A restorative material for Class III cavities must, besides being functional, be esthetically satisfactory, providing good working conditions and several shade and color options. A clinical evaluation was initiated to compare the suitability of resin composite and glass-ionomer cement materials for such restorations.Method and materials: Forty-two Class III conservative cavities, esthetically important because of facial extensions, were selected. Resin composite restorations were placed in 21 cavities, and the remaining 21 were restored with glass-ionomer cement. The following characteristics were studied: color or-esthetics, anatomic shape, surface texture, staining, marginal infiltration, dental plaque retention, and occurrence of fracture. After 24 months, the restorations were evaluated.Results: the only statistically significant difference between the resin composite and glass-ionomer cement restorations in the experimental period involved color or esthetics.Conclusion: Resin composites and glass-ionomer materials provide excellent functional and esthetic results in Class III cavities when properly indicated.

Investigation of Partamona helleri (Apidae, Meliponini) B chromosome origin. An approach by microdissection and whole chromosome painting

The stingless bee Partamona helleri in southeast Brazil shows the regular chromosome number 2n = 34 and a variable number of up to four minute B1 or B2 chromosomes. Previous cytogenetic analyses have indicated morphological similarities between the B1 chromosome and chromosome segments in the regular karyotype. In this study, microdissection and chromosome painting were employed along with C banding, NOR banding, and base-specific fluorochrome staining to investigate the origin of the B1 chromosome in P. helleri. B1-generated probe hybridized exclusively to B1 chromosomes. This result suggests an independent origin from the regular karyotype or, alternatively, that the B chromosome may have suffered substantial genetic alterations along its independent evolution. The absence of higher dosages of these small B chromosomes in this population of P. helleri may be related to the existence of either a genetic or cytogenetic constraint in the establishment of such high numbered karyotypes. © 2012 INRA, DIB and Springer-Verlag, France.

Processing and hygrothermal effects on viscoelastic behavior of glass fiber/epoxy composites

Fiber reinforced epoxy composites are used in a wide variety of applications in the aerospace field. These materials have high specific moduli, high specific strength and their properties can be tailored to application requirements. In order to screening optimum materials behavior, the effects of external environments on the mechanical properties during usage must be clearly understood. The environmental action, such as high moisture concentration, high temperatures, corrosive fluids or ultraviolet radiation (UV), can affect the performance of advanced composites during service. These factors can limit the applications of composites by deteriorating the mechanical properties over a period of time. Properties determination is attributed to the chemical and/or physical damages caused in the polymer matrix, loss of adhesion of fiber/resin interface, and/or reduction of fiber strength and stiffness. The dynamic elastic properties are important characteristics of glass fiber reinforced composites (GRFC). They control the damping behavior of composite structures and are also an ideal tool for monitoring the development of GFRC's mechanical properties during their processing or service. One of the most used tests is the vibration damping. In this work, the measurement consisted of recording the vibration decay of a rectangular plate excited by a controlled mechanism to identify the elastic and damping properties of the material under test. The frequency amplitude were measured by accelerometers and calculated by using a digital method. The present studies have been performed to explore relations between the dynamic mechanical properties, damping test and the influence of high moisture concentration of glass fiber reinforced composites (plain weave). The results show that the E' decreased with the increase in the exposed time for glass fiber/epoxy composites specimens exposed at 80 degrees C and 90% RH. The E' values found were: 26.7, 26.7, 25.4, 24.7 and 24.7 GPa for 0, 15, 30, 45 and 60 days of exposure, respectively. (c) 2005 Springer Science + Business Media, Inc.

Undoped and calcium doped borate glass system for thermoluminescent dosimeter

Borate glasses present an absorption coefficient very close to that of human tissue. This fact makes some borates ideal materials to develop medical and environmental dosimeters. Glass compositions with calcium tetraborate (CaB4O7) and calcium metaborate (CaB2O4), such as the xCaB(4)O(7) - (100-x)CaB2O4 System (0 <= x <= 100 wt%) were obtained by the traditional melting/quenching method. A phenomenon widely known as the 'boron anomaly' was observed in our thermal analysis measurements, as indicated by the increase of T, and the appearance of a maximum value in the composition with 40 wt% of CaB2O4. The Dy doped and Li co-doped 80CaB(4)O(7)-20CaB(2)O(4) (Wt%) glass samples were studied by the thermoluminescence technique. The addition of Dy improved the signal sensitivity in about three times with respect to the undoped glass sample. The addition of Li as a co-dopant in this glass caused a shift to a lower temperature of about 20 degrees C in the main glow peak. The structural analysis of the 80CaB(4)O(7)-20CaB(2)O(4) (wt%) undoped and doped samples were studied through infrared absorption. We have noted an increase in the coordination number of the boron atoms from 3 to 4, i.e., the conversion of the BO3 triangular structural units into BO4 tetrahedra. (c) 2006 Elsevier B.V.
