Temperature and emissivity separation from ASTER data for low spectral contrast surfaces
2007
Abstract The performance of Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) thermal infrared (TIR) data product algorithms was evaluated for low spectral contrast surfaces (such as vegetation and water) in a test site close to Valencia, Spain. Concurrent ground measurements of surface temperature, emissivity, and atmospheric radiosonde profiles were collected at the test site, which is a thermally homogeneous area of rice crops with nearly full vegetation cover in summer. Using the ground data and the local radiosonde profiles, at-sensor radiances were simulated for the ASTER TIR channels and compared with L1B data (calibrated at-sensor radiances) showing discrepancies up…
Comparison between different sources of atmospheric profiles for land surface temperature retrieval from single channel thermal infrared data
2012
Abstract Different sources of atmospheric water vapor and temperature profiles were used with a radiative transfer model for retrieving land surface temperature (LST) from thermal infrared remote sensing data with the so-called single channel (SC) method. Retrieved LSTs were compared to concurrent ground measurements over homogeneous rice fields to assess the accuracy of the atmospheric profiles. These included radiosonde balloons launched at the test site near-concurrently to satellite overpasses, re-analysis profiles from the National Centers for Environmental Prediction (NCEP), and satellite sounder products from the Atmospheric Infrared Sounder (AIRS) and the Moderate Imaging Spectrorad…
The Effect of Nicotinamide on Microcirculatory Function, Tissue Oxygenation and Bioenergetic Status in Rat Tumors
1994
The failure of many attempts to improve tumor oxygenation - and thus the outcome of standard radiotherapy - may be due to the fact that the occurrence of hypoxia in tumors is not solely a result of diffusion-limited “chronic” hypoxia but is also due to temporary flow cessations in microregional tumor perfusion which have been shown to occur in tumor tissue1. As a result, attempts have more recently been made to reduce hypoxia in tumors through the reduction of tumor perfusion fluctuations. The benzamide analog nicotinamide is an agent which has recently received attention in this respect. It has been reported to be an effective, tumor-specific radiosensitizer in several tumor models, an eff…

A fully automatic approach for multimodal PET and MR image segmentation in gamma knife treatment planning
2017
The aim of this study is to combine Biological Target Volume (BTV) segmentation and Gross Target Volume (GTV) segmentation in stereotactic neurosurgery.Our goal is to enhance Clinical Target Volume (CTV) definition, including metabolic and morphologic information, for treatment planning and patient follow-up.We propose a fully automatic approach for multimodal PET and MR image segmentation. This method is based on the Random Walker (RW) and Fuzzy C-Means clustering (FCM) algorithms. A total of 19 brain metastatic tumors, undergone stereotactic neuro-radiosurgery, were retrospectively analyzed. A framework for the evaluation of multimodal PET/MRI segmentation is presented, considering volume…
Transverstites re-existences: A counterhistory from the visual difference in Peru
2018
El vínculo entre naturaleza y deshumanización es un discurso moderno colonial de género que mantiene su vigencia mediante la basurización simbólica y concreta de quienes son vistos como inferiores, antinaturales y hasta como animales, convertidos en un desecho de la sociedad. Una forma de visualizar al otro como elemento sobrante del sistema simbólico. En este sentido, maniobrar en el campo de la visualidad travesti, sus convenciones y estereotipos, se convierte en una práctica de resistencia en tanto que se enfrenta al régimen escópico eurocéntrico disciplinante, astutamente camuflado. Pero, igualmente, de re-existencia, al proponer la co-presencia visual de la diferencia, y por ende, la e…
La imagen de Rusia en la prensa valenciana
2015
La imagen de Rusia en la prensa valenciana refleja los problemas de la percepción de un país extranjero en los medios de comunicación masiva de otro país. El tema se refiere a la ciencias de comunicación y da una visión panorámica del análisis de la prensa de la Comunidad Valenciana basándose en uno de los periódicos más emblemáticos regionales de esta región que es el periódico Las provincias. Es una profunda reflexión sobre la imagen de Rusia en la conciencia colectiva que se crea a base de la información transmitida por los medios de comunicación masiva (en este caso por la prensa) y los estereotipos existentes sobre este país en España. Se realiza un análisis detallado de las informacio…
Forms and modes of living in the work of Remedios Varo
2010
Remedios Varo es una pintora nacida en Anglés, un pueblo de la provincia de Gerona al norte de Barcelona. Artista formada académicamente en la Escuela de Bellas Artes de Madrid, cuya vida estará marcada por la inestabilidad política de España y los acontecimientos de la guerra civil, condiciones que la obligan a emigrar primero a Francia, donde se pone en contacto con el grupo de los surrealistas, movimiento artístico que infl uye profundamente en su obra. Contactos que se verán interrumpidos por la ocupación nazi en Francia en 1940. Situación que la obliga a emigrar a México. En este país Remedios Varo vive hasta su muerte, allí desarrolla su trabajo, sus búsquedas artísticas, y sobre todo…
A New Methodology to Assess Territorial Competence for Sustainable Local Development: The READI® (Resources-Actors-Dynamics) Matrix
2021
[EN] The ability of a territory to manage certain sustainable development processes increasingly depends on its capacity to apply previous diagnostic processes to its current situation. For this reason, methodologies that facilitate the detection of needs and/or potentialities of the territory are key to meeting its anticipated sustainable development goals. We present the most notable results of the research methodology carried out in the province of Valencia (Spain) that has enabled the construction of a matrix of indicators that allow these previous diagnostic processes to be put into practice at a local level, based on the participation of the territory's socioeconomic actors.
PERIODISMO Y RESPONSABILIDAD SOCIAL EMPRESARIAL:
2020
El propósito de este texto es revisar la noción del periodismo, como oficio y como empresa y replantear su responsabilidad desde el carácter corporativo en función de la democracia, como bien social. A través de un análisis crítico de la visión dicotómica de la ética (la profesional y la empresarial) proponemos un marco filosófico moral para los medios de comunicación social. The aim of this text is to review the notion of journalism, as a trade and as business, as well to reconsider its responsibility from a corporative nature in support of democracy, understood this as social good. Through a critical analysis on a dichotomous view of ethics (professional and business), we propose a moral …
