La lectura "palimpsestuosa" en textos e imágenes : Elementos de transtextualidad en dos libros álbum de Anthony Browne

Este trabajo se sumerge en el terreno de la transtextualidad (Genette, 1989) en el análisis de dos libros-álbum del laureado artista inglés Anthony Browne. El libro-álbum es un género relativamente nuevo, fruto de la posmodernidad y terreno fértil para la experimentación, cuya característica principal es la intención cooperativa del texto escrito y la imagen para la construcción de significados, lo que trae aparejado un lector implícito dispuesto a asumir un rol activo para, a partir de lo que expresan tanto lo escrito como lo ilustrado, llegar a co-crear un mensaje. La obra de Browne rebosa en referencias, préstamos, alusiones y deudas tanto de las artes visuales como de la literatura. Uno de los mecanismos principales que utiliza tanto en sus textos como en sus imágenes es la puesta en relación de estos con otras obras tanto literarias como visuales, pero también con otros medios (cine, televisión, revistas, periódicos). Tomando como punto de partida una estética cuyo origen es el libro para niños, va más allá, complejiza una invitación a los sentidos y ofrece diferentes capas de significado que serán descodificadas de diversos modos acorde a la experiencia del destinatario, el cual es doble (niños y adultos). ;Nuestro objetivo en este caso es analizar en sus libros En el Bosque (Into the Forest, 2004) y Willy el Soñador (Willy the Dreamer, 1997) el uso de dos mecanismos de la transtextualidad: la intertextualidad y la hipertextualidad (y dentro de esta, principalmente, la parodia). Respecto del primer libro, estudiaremos las conexiones intertextuales establecidas desde el texto escrito y el ilustrado con los cuentos tradicionales como "La Caperucita Roja", "Hansel y Gretel", etc. Y respecto del segundo, observaremos cómo las ilustraciones parodian obras famosas de las artes visuales, muchas de ellas de René Magritte, y hacen guiños sobre relatos muy conocidos como, por ejemplo, Alicia en el país de las maravillas (1863), de Lewis Carrol. ;Desde el ámbito de la Literatura Comparada, en su aspecto abarcativo de otras artes que se relacionan con la literatura, la interpelan e incluso la modifican, proponemos una mirada sobre un género que, debido a su novedad, no ha sido muy estudiado, y una especial atención a la literatura para niños, la cual suele no ser tenida en cuenta en los estudios sobre literatura en general

Microbial Fuel Cells: Methodology and Technology

Microbial fuel cell (MFC) research is a rapidly evolving field that lacks established terminology and methods for the analysis of system performance. This makes it difficult for researchers to compare devices on an equivalent basis. The construction and analysis of MFCs requires knowledge of different scientific and engineering fields, ranging from microbiology and electrochemistry to materials and environmental engineering. DescribingMFCsystems therefore involves an understanding of these different scientific and engineering principles. In this paper, we provide a review of the different materials and methods used to construct MFCs, techniques used to analyze system performance, and recommendations on what information to include in MFC studies and the most useful ways to present results.

Noncovalent coatings for the separation of synthetic polypeptides by nonaqueous capillary electrophoresis

Recently, we demonstrated the possibility to extend the range of capillary electrophoresis (CE) applications to the separation of non-water-soluble synthetic polymers. This work focuses on the control of the electro-osmotic flow (EOF) and on the limitation of the solute adsorption in nonaqueous electrolytes. For these purposes, different strategies were investigated. For the initial, a viscous additive (ethylene glycol or glycerol) was used in the electrolyte in order to decrease the EOF magnitude and, possibly, to compete with solute adsorption. A second strategy was to modify, before separation, the fused-silica capillary wall by the adsorption of poly(ethylene oxide) (PEO) via hydrogen bonding. The influence of the molecular mass of the adsorbed PEO on the EOF magnitude and direction was studied in electrolytes based on methanol/acetonitrile mixtures containing ammonium ions. For PEO molecular masses above 1000 g/mol, reversed (anodic) EOF were reported in accordance with previous results obtained with PEO covalently bonded capillaries. The influence of the nature and the concentration of the background electrolyte cation on the EOF magnitude and direction were also investigated. A third strategy consisted in modifying the capillary wall by the adsorption of a cationic polyelectrolyte layer. Advantageously, this polyelectrolyte layer suppressed the adsorption of the polymer solutes onto the capillary wall. The results obtained in this work confirm the high potential and the versatility of CE for the characterization of ionizable organic polymers in nonaqueous media.

Nonaqueous capillary zone electrophoresis of synthetic organic polypeptides

Poly(Nε-trifluoroacetyl-l-lysine) was used as a model solute to investigate the potential of nonaqueous capillary electrophoresis (NACE) for the characterization of synthetic organic polymers. The information obtained by NACE was compared to that derived from size exclusion chromatography (SEC) experiments, and the two techniques were found to be complimentary for polymer characterization. On one hand, NACE permitted (i) the separation of oligomers according to their molar mass and (ii) the separation of the polymers according to the nature of the end groups. On the other hand, SEC experiments were used for the characterization of the molar mass distribution for higher molar masses. Due to the tendency of the solutes (polypeptides) to adsorb onto the fused-silica capillary wall, careful attention was paid to the rinsing procedure of the capillary between runs in order to keep the capillary surface clean. For that purpose, the use of electrophoretic desorption under denaturating conditions was very effective. Optimization of the separation was performed by studying (i) the influence of the proportion of methanol in a methanol/acetonitrile mixture and (ii) the influence of acetic acid concentration in the background electrolyte. Highly resolved separation of the oligomers (up to a degree of polymerization n of ∼50) was obtained by adding trifluoroacetic acid to the electrolyte. Important information concerning the polymer conformations could be obtained from the mobility data. Two different plots relating the effective mobility data to the degree of polymerization were proposed for monitoring the changes in polymer conformations as a function of the number of monomers.

Manager's Perspectives on the Provision of Healthy Meals in Resort Hotels

This research aimed to understand hotel managers’ attitudes toward the provision of healthy meals. The study deployed a mailing survey to assess the managers’ perceptions. A closed-ended questionnaire was developed evaluating the role of healthy food choices in Mediterranean resort hotels. The findings showed that (1) atmosphere in the restaurant, (2) appealing display of food, and (3) eating habits and lifestyle were more important than personal health when selecting a meal. In addition, this study suggested that the managers were not ready to promote healthy eating because their customers would have been critical of this new service concept

Database of the GLAMAP project

A uniform chronology for foraminifera-based sea surface temperature records has been established in more than 120 sediment cores obtained from the equatorial and eastern Atlantic up to the Arctic Ocean. The chronostratigraphy of the last 30,000 years is mainly based on published d18O records and 14C ages from accelerator mass spectrometry, converted into calendar-year ages. The high-precision age control provides the database necessary for the uniform reconstruction of the climate interval of the Last Glacial Maximum within the GLAMAP-2000 project.

Enhanced Volatile Organic Compounds emissions and organic aerosol mass increase the oligomer content of atmospheric aerosols

Secondary organic aerosol (SOA) accounts for a dominant fraction of the submicron atmospheric particle mass, but knowledge of the formation, composition and climate effects of SOA is incomplete and limits our understanding of overall aerosol effects in the atmosphere. Organic oligomers were discovered as dominant components in SOA over a decade ago in laboratory experiments and have since been proposed to play a dominant role in many aerosol processes. However, it remains unclear whether oligomers are relevant under ambient atmospheric conditions because they are often not clearly observed in field samples. Here we resolve this long-standing discrepancy by showing that elevated SOA mass is one of the key drivers of oligomer formation in the ambient atmosphere and laboratory experiments. We show for the first time that a specific organic compound class in aerosols, oligomers, is strongly correlated with cloud condensation nuclei (CCN) activities of SOA particles. These findings might have important implications for future climate scenarios where increased temperatures cause higher biogenic volatile organic compound (VOC) emissions, which in turn lead to higher SOA mass formation and significant changes in SOA composition. Such processes would need to be considered in climate models for a realistic representation of future aerosol-climate-biosphere feedbacks.
