Dos veces Julio. Sobre algunas memorias fotográficas del pasado reciente en la Argentina
2016
Resumen: El punto de partida de este articulo es una foto de Julio Lopez, ex detenido-desaparecido de la pasada dictadura argentina y vuelto a desaparecer en 2006 tras dar testimonio en el juicio que condeno al represor Miguel Etchecolatz a prision perpetua. Una foto de Lopez ya vista sera ahora reinsertada en otro contexto, duplicada para ser dada nuevamente a la mirada. Desde ella se desplegaran las singularidades de algunas otros artefactos visuales entendidos como memorias fotograficas de la historia reciente argentina ligada a la pasada dictadura. Fotos que en sus mismos procedimientos de construccion de lo pasado se van conformando como artefactos de memoria, tensando particularmente…
Experimental investigation on different rainfall energy harvesting structures
2018
In this paper proposes an experimental comparison between different rainfall harvesting devices and the study of the corresponding electrical rectifying circuit. More in detail, three harvesting structures are considered: the cantilever, the bridge and the floating circle. For each of the proposed structure, different waveforms have been acquired and discussed. The processed data have been compared in order to suggest the best choice for the rectifying circuit, from the simplest one to the most endorsed in the technical literature.
Climate Change Genomics Calls for Standardized Data Reporting
2020
The advent of new and affordable high-throughput sequencing techniques allows for the investigation of the genetic basis of environmental adaptation throughout the plant and animal kingdom. The framework of genotype-environment associations (GEA) provides a powerful link by correlating the geographic distribution of genotype patterns of individuals or populations with environmental factors on a spatial scale. We coarsely review the short history of GEA studies, summarizing available studies, organisms, data type, and data availability for these studies. GEA is a powerful tool in climate change research and we therefore focus on climate variables as environmental factors. While our initial a…
What has been thought and taught on the lunar influence on plants in agriculture? Perspective from physics and biology
2020
This paper reviews the beliefs which drive some agricultural sectors to consider the lunar influence as either a stress or a beneficial factor when it comes to organizing their tasks. To address the link between lunar phases and agriculture from a scientific perspective, we conducted a review of textbooks and monographs used to teach agronomy, botany, horticulture and plant physiology; we also consider the physics that address the e ects of the Moon on our planet. Finally, we review the scientific literature on plant development, specifically searching for any direct or indirect reference to the influence of the Moon on plant physiology. We found that there is no reliable, science-based evi…
A unified vegetation index for quantifying the terrestrial biosphere
2021
[EN] Empirical vegetation indices derived from spectral reflectance data are widely used in remote sensing of the biosphere, as they represent robust proxies for canopy structure, leaf pigment content, and, subsequently, plant photosynthetic potential. Here, we generalize the broad family of commonly used vegetation indices by exploiting all higher-order relations between the spectral channels involved. This results in a higher sensitivity to vegetation biophysical and physiological parameters. The presented nonlinear generalization of the celebrated normalized difference vegetation index (NDVI) consistently improves accuracy in monitoring key parameters, such as leaf area index, gross prim…
A Marine Spatial Planning Approach to Minimize Discards: Challenges and Opportunities of the Landing Obligation in European Waters
2018
A sensible approach to minimize discards is to avoid areas or seasons where unwanted catch may be present. The implementation of a Marine Spatial Planning (MSP) approach to discard management requires the understanding of marine biological processes, as well as fishing conditions at a defined spatial scale. Mathematical models that analyze the spatio-temporal conditions of selected fishing areas allow the definition of different scenarios where discards are minimized by avoiding fishing for unwanted species and/or illegal specimens. Here we show some examples of how particular spatial models can be used for advice on MSP for discards. We introduce a geoserver GIS platform developed to produ…
Paisaje y nacionalismo en el primer franquismo
2016
Assuming the theoretical idea widely developed by Human Geography that landscapes are cultural constructions with the capacity to become symbolic elements within nationalist discourses, this article explores the context of early Francoism. The aim of these pages is to analyze landscape sensibility as well as the landscape idea developed by the francoist nationalist discourse by trying to draw out three inherent elements in it: first of all, following Oliver Zimmer’s work, the nationalization of nature, this is to say, the consideration that nature expresses the community’s myths, events or memories; secondly, the naturalisation of the nation, that projects upon landscapes the capacity to de…

Mediterranean identities - environment, society, culture
2017
The Mediterranean Sea, one of the most complex marine ecosystems, is inhabited by a rich and diverse biota which is disproportionate to its dimensions. It is cur‐ rently affected by different pressures, mainly driven by human activities such as cli‐ mate change and bioinvasions. This Sea, also due to its geographic position (wedged between the temperate climate of central Europe and the arid climate of northern Africa), seems to be one of the regions most susceptible to global climate change. The increased rates of introduction and spread of marine alien species may represent a supplementary stress factor to Mediterranean marine native biota already challenged by climatic abnormalities. The…
