Amenability and co-amenability of algebraic quantum groups

We define concepts of amenability and co-amenability for algebraic quantum groups in the sense of A. Van Daele. We show that co-amenability of an algebraic quantum group always implies amenability of its dual. Various necessary and/or sufficient conditions for amenability or co-amenability are obtained. Co-amenability is shown to have interesting consequences for the modular theory in the case that the algebraic quantum group is of compact type.Comment: 25 pages, with some minor corrections, as to appear in the IJMM

Co-Amenability of compact quantum groups

We study the concept of co-amenability for a compact quantum group. Several conditions are derived that are shown to be equivalent to it. Some consequences of co-amenability that we obtain are faithfulness of the Haar integral and automatic norm-boundedness of positive linear functionals on the quantum group's Hopf *-algebra (neither of these properties necessarily holds without co-amenability).Comment: 25 pages.

FRAMES OF GARDEN. GRAPHICAL VISIT THROUGH THE IDEALS OF THE MODERN DOMESTIC GARDEN

[EN] The imaginary of drawing is enlarged when we visit the architectural drawings graphically. Touring the modern home garden through its graphic visit helps to reveal the ideas expressed in the delimitation of its forms. Starting in the sinuous curves of Burle Marx, witnessing the static landscapes of Le Corbusier and the views framed by Mies van der Rohe, being introduced in the designs of Garrett Eckbo and then traveling across the different adaptations of nature in the drawings of Erskine, Neutra and Coderch will be the first steps in a process of a fascinating, long and lonely discovery. All these frames of garden suggest ways of interpreting the tangible reality that it is represented with the strokes of the drawing. This methodology invites anyone to read in the design its original and future desires, which as single words, they want to teach the meaning of the lines that shape it.[ES] El imaginario del dibujar se amplia cuando visitamos gráficamente los dibujos de arquitectura.

The recovery of the Other: focusing images of architecture

El tiempo presente está determinado por la visualidad obsesiva de las imágenes de arquitectura. Bajo esta condición, la crítica de arquitectura puede aún formular instrumentos de análisis apropiados a la lectura de una arquitectura convertida en imagen con el fin de redescubrir la presencia del hombre en ella. Esta labor crítica permite al arquitecto emprender la recuperación de lo Otro como una necesidad de la contemporaneidad para devolver la "humanitas" al centro de la arquitectura.ENG: The present epoch is determined by the obsessive vision of architecture images. Under this condition, criticism could still develop new analytical tools appropriate to the reading of an architecture converted into image in order to unveil the presence of man in it. This view of criticism allows the architect to undertake the recovery of the Other as a contemporary need to return the "humanitas" at the centre of the architecture.Peer Reviewe

La causa parasitaria de la "seca" de los Quercus

La “Seca” de los Quercus es una enfermedad compleja que, en la península Ibérica, afecta principalmente a encinas y alcornoques, tanto a árboles agrupados como dispersos. La causa parasitaria más importante que contribuye al desarrollo de esta enfermedad es la actuación del hongo Phytophthora cinnamomi Rands. Este parásito primario habitante del suelo se detectó en España a finales de los años 80, estando en la actualidad muy presente en las comunidades autónomas de: Andalucía, Castilla La Mancha, Castilla y León, Extremadura y Madrid. En este artículo se explica de forma compresible los caracteres morfológicos del agente parasitario, su actividad como agente patógeno causal de la enfermedad y su dinámica (reproducción, conservación y dispersión).___________________________________The “Seca” (oak decline disease) of the Quercus trees is a complex disease that in the Iberian peninsula attack the holm oak and corck oak both in clusters and dispersed trees. The parasite cause more important that contributes to develop of these disease is the activity of the fungus Phytophthora cinnamomi Rands. This pathogen is a primary parasite soil habitant and was detected in Spain at the end the 80’s. Current this pathogen is present in the Autonomic Comunities of Andalusian, , Castilla La Mancha, Castilla y León, Extremadura and Madrid. In the text is indicate in understandable way the morpholgical characters of the parasite agent, its pathogen activity as well as its dynamic (reproduction, conservation and dispersion)

Historical flash floods retromodelling in the Ondara River in Tàrrega (NE Iberian Peninsula)

Flash floods in the Ondara River have caused many fatalities and damages in the town of Tàrrega in the last 400 yr. Unfortunately, no flow records are available. <br><br> However, floods can sometimes be reconstructed thanks to available historical information: limnimarks, written accounts and archaeological surveys. Indeed, from these data and using the retromodelling method on three different scenarios to take into account morphology changes, the peak flows of the seven greatest floods occurred in Tàrrega since the 17th century were estimated. <br><br> The results showed that the heaviest flood's specific peak flow (10.7 m<sup>3</sup> s<sup>−1</sup> km<sup>−2</sup>) ranks among the highest ever modelled or measured in similar-sized catchments in the Western Mediterranean region. The results pointed out, as well, that the changes in channel's morphology (mainly, the disappearance of a mediaeval bridge under sediment) caused by one of the floods increased the hydraulic capacity of a crucial cross-section. All this resulted in modest floods invading the town less often, but with much faster and, thus, more destructive flows. <br><br> A preliminary estimation of the results' uncertainty was 4% for great floods and 18% for modest floods. <br><br> The reconstructed peak flows will be introduced in a database for a future use in climatic and hydrological studies

Green Coastal Zones: Nodes and Connectors as Strategy of Urban Regeneration

[EN] The landscape of Valencian Community is a resource with great cultural and heritage value. The system of Green Infrastructure ensures a continuous network of unbuilt areas with high environmental, cultural and visual value that also serves as ecological and functional connectors. The ERAM research project `Strategies for sustainable regeneration of tourist settlements on the Mediterranean coast¿ (2012¿14) identifies and analyzes the different types of coastal tourist towns of the Valencian region considering their needs for urban regeneration. It proposes strategies for prospective actions that can serve as a model for the regeneration of coastal tourist resorts. The determination of Green Coastal Zones (GCZ) aims to define their potential for urban regeneration in order to establish criteria for regional planning and urban design processes that will foster innovation in mature tourist destinations. The results show the potential of the 11 ERAM areas whose nodal connectivity and multifunctional landscape defines the framework for adaptive design strategies that may present alternative scenarios for touristic settlements.The ERAM research project ‘Strategies for sustainable regeneration of tourist settlements on the Mediterranean coast’ (2012–14) identifies and analyzes the different types of coastal tourist towns of the Valencian region considering their needs for urban regeneration.Tuset Davó, JJ.
