El paisaje en la ordenación del territorio. La experiencia del Observatorio del Paisaje de Cataluña

Ante la progresiva degradación de nuestros paisajes se hace necesario, por una parte, incluir el paisaje en la ordenación del territorio y, por otra, incrementar la sensibilización ciudadana sobre los valores del paisaje. Para conseguir este doble objetivo se creó en 2005 el Observatorio del Paisaje de Cataluña, un consorcio público independiente que actúa simultáneamente como entidad de asesoramiento de la Administración y como ente de concienciación de la sociedad en materia de paisaje. Una de sus principales funciones es la elaboración de los catálogos de paisaje de Cataluña, un instrumento novedoso para la incorporación del paisaje en la ordenación del territorio y un elemento clave para facilitar la conexión entre el planeamiento territorial y el urbanístico en lo referente a la implementación de políticas de paisaje. Los catálogos definen líneas estratégicas y directrices concretas que pueden contribuir a mejorar la calidad de los paisajes y, en definitiva, la calidad de vida de los ciudadanos

Model-based Segmentation and Fusion of 3D Computed Tomography and 3D Ultrasound of the Eye for Radiotherapy Planning

Computed Tomography (CT) represents the standard imaging modality for tumor volume delineation for radiotherapy treatment planning of retinoblastoma despite some inherent limitations. CT scan is very useful in providing information on physical density for dose calculation and morphological volumetric information but presents a low sensitivity in assessing the tumor viability. On the other hand, 3D ultrasound (US) allows a highly accurate definition of the tumor volume thanks to its high spatial resolution but it is not currently integrated in the treatment planning but used only for diagnosis and follow-up. Our ultimate goal is an automatic segmentation of gross tumor volume (GTV) in the 3D US, the segmentation of the organs at risk (OAR) in the CT and the registration of both modalities. In this paper, we present some preliminary results in this direction. We present 3D active contour-based segmentation of the eye ball and the lens in CT images; the presented approach incorporates the prior knowledge of the anatomy by using a 3D geometrical eye model. The automated segmentation results are validated by comparing with manual segmentations. Then, we present two approaches for the fusion of 3D CT and US images: (i) landmark-based transformation, and (ii) object-based transformation that makes use of eye ball contour information on CT and US images.

Old ferricrete landscape dismantling in Central Africa rain forest zone: formation of the present downslope iron accumulations.

Present downslope iron accumulations were investigated in the rainforest zone in southern Cameroon. Six clay and Fe-hydroxide dominated patterns have been identified and occur on the lower part of hill slopes. They can be subdivided in three different sequences, related to gentle, moderate or steep slopes. They are discontinuous with respect to the dismantling zone of the old ferricrete cap formed at Cretaceous period. They show a gradual development from a soft Fe-crust (carapace) to a vesicular facies that will, with time, cover the whole landscape again.

Shaping the interaction landscape of bioactive molecules.

MOTIVATION: Most bioactive molecules perform their action by interacting with proteins or other macromolecules. However, for a significant fraction of them, the primary target remains unknown. In addition, the majority of bioactive molecules have more than one target, many of which are poorly characterized. Computational predictions of bioactive molecule targets based on similarity with known ligands are powerful to narrow down the number of potential targets and to rationalize side effects of known molecules. RESULTS: Using a reference set of 224 412 molecules active on 1700 human proteins, we show that accurate target prediction can be achieved by combining different measures of chemical similarity based on both chemical structure and molecular shape. Our results indicate that the combined approach is especially efficient when no ligand with the same scaffold or from the same chemical series has yet been discovered. We also observe that different combinations of similarity measures are optimal for different molecular properties, such as the number of heavy atoms. This further highlights the importance of considering different classes of similarity measures between new molecules and known ligands to accurately predict their targets.

Stratigraphical discontinuities, tropical landscape evolution and soil distribution relationships in a case study in SE-Brazil

On a regional summit surface in the county of Piracicaba (SP) within the Peripheric Depression of São Paulo, formed of discontinued flattened tops, there is an abrupt transition between a Typic Hapludox and a Kandiudalfic Eutrudox, together with two stoneline layers. Using stratigraphical, mineralogical, and cartographic studies, this transition and the soil distribution of this surface were studied, correlating them with the different parent materials and the morphoclimatic model of landscape evolution in Southeastern Brazil. The Typic Hapludox was formed on a sandy Cenozoic deposit (Q) that overlies a pellitic deposit of the Iratí formation (Pi), representing a regional erosive discordance. Westwards to the Piracicaba River, this sequence is interrupted by a diabase sill overlain by a red clayey material which gave origin to the Kandiudalfic Eutrudox. Two post-Permian depositional events were identified by the two stonelines and stratigraphical discontinuities. The first event generated the deposition of a sandy sediment in the form of levelled alveoluses on regional barriers, most of these formed by dikes and diabase sills, probably during a drier phase. The second depositional event, leading to the deposition of the red clay was probably the dissection of the previously formed pediplane during a humid climate, followed by another pedimentation process during a later, drier period.

Comunicar la ciudad desde el paisaje: hacia una teoría del landscape branding

La necesidad de descodificar los significados inherentes al paisaje, la interactuación sociedadpaisaje (comunicación intra e interpersonal) y, más recientemente, los usos de paisaje a modo de aparador territorial mediático en el ámbito, por ejemplo, de la comunicación publicitaria, del citymarketing o del place branding (comunicación masiva), sirven para plantear el estudio de lo que, de algún modo, representa la persuasión del paisaje, la cual incluye claros tintes emocionales y simbólicos y, por tanto, también comunicacionales. El paisaje en su condición de imagen y/o rostro del territorio acumula la esencia del mensaje implícito en el espacio, posicionándose, de este modo, como la gran metáfora comunicativa de la ciudad. En este sentido, el trabajo de comunicación específico con el intangible paisajístico, unido a la reciente explosión de las denominadas geografías emocionales, plantea una teoría del mensaje territorial basada en la unión de las variables geografía, paisaje, emoción y comunicación. Históricamente, de los estudios de paisaje se han ocupado los geógrafos, arquitectos, historiadores, sociólogos o ambientólogos, entre muchos otros, sin embargo, el paisaje se ha mantenido poco explorado desde la perspectiva de la comunicación. En este sentido, es notoria la proliferación de análisis que ponen el acento en el papel que desarrolla el territorio como mediador de procesos de comunicación o en el estudio de procesos de retroalimentación entre la sociedad y sus espacios (cognición y/o percepción). El actual mercadeo identitario con los lugares se concreta en la creciente producción de marcas territoriales, las cuales acumulan, en los últimos tiempos, un importante protagonismo.
