Gluing the ‘unwettable’: soil-dwelling harvestmen use viscoelastic fluids for capturing springtails
2014
Gluing can be a highly efficient mechanism of prey capture, as it should require less complex sensory–muscular feedback. Whereas it is well known in insects, this mechanism is much less studied in arachnids, except spiders. Soil-dwelling harvestmen (Opiliones, Nemastomatidae) bear drumstick-like glandular hairs (clavate setae) at their pedipalps, which were previously hypothesized to be sticky and used in prey capture. However, clear evidence for this was lacking to date. Using high-speed videography, we found that the harvestman Mitostoma chrysomelas was able to capture fast-moving springtails (Collembola) just by a slight touch of the pedipalp. Adhesion of single clavate setae increased p…
Hidden Mediterranean diversity: Assessing species taxa by molecular phylogeny within the opilionid family Trogulidae (Arachnida, Opiliones)
2009
This is the first comprehensive study to evaluate the relationships between the western palearctic harvestman families Dicranolasmatidae, Trogulidae and Nemastomatidae with focus on the phylogeny and systematics of Trogulidae, using combined sequence data of the nuclear 28S rRNA and the mitochondrial cytochrome b gene. Bayesian analysis and Maximum parsimony do not reliably resolve Dicranolasma as distinct family but place it on a similar phylogenetic level as several lineages of Trogulidae. Nemastomatidae and Trogulidae turned out to be monophyletic, as did genera Anelasmocephalus and Trogulus within the Trogulidae. The genera Calathocratus, Platybessobius and Trogulocratus each appeared p…
Contribución de los Sistemas de Información Geográfica al estudio del Neolítico peninsular, algunos ejemplos de las vertientes cantábrica y mediterrá…
2008
El estudio comparativo de dos áreas de la Península Ibérica bien dispares desde el punto de visa ecológico (la una forma parte de la región eurosiberiana y la otra de la región mediterránea) permite valorar los procesos históricos que tuvieron lugar en el contexto de la adopción de la vida agrícola en la Península Ibérica y la transformación del paisaje consecuente. El objetivo primordial de los análisis que se presentan es el mejor conocimiento de los desarrollos culturales en el Ho\oceno Reciente. La integración de datos regionales y de excavación de dos regiones distintas es sólo posible a través de la utilización de nuevas tecnologías de análisis espacial, como son los Sistemas de Infor…

Violencia directa en los curricula de instituciones educativas emplazadas en contextos de conflicto armado
2015
La tesis propuesta explora y profundiza en las distintas manifestaciones u objetivaciones del curriculum escolar, en la fase preactiva de tres instituciones educativas que se encuentran situadas en la ciudad de Medellín. Metrópoli colombiana de un histórico y manifiesto tejido de violencia directa por medios armados. Y esto con el propósito de conocer la forma en que son tratados los contenidos escolares sobre violencia directa y/o armada. Todo ello en el marco de preguntas del tipo: ¿qué ocurre de especial, entre otras cosas con los planes de estudio, cuando algunas instituciones educativas “modernas” se encuentran emplazadas en comunidades con altos índices de violencia directa por medios…
Aula Virtual. Evolució del maquinari i millora de resultats
2009
Las Tecnologías de la Información y la Comunicación (TIC) han contribuido al desarrollo de plataformas e.learning de apoyo a los procesos de enseñanza-aprendizaje. Actualmente, la mayoría de universidades cuentan con algún tipo de sistema de gestión del aprendizaje (en inglés, LMS). El óptimo uso de estas plataformas requiere que integren las aplicaciones preexistentes de forma transparente. Esto se consigue con el uso de una arquitectura robusta. En este artículo expondremos la implementación y arquitectura del LMS integrado de la Universitat de València y la evolución de su hardware para adecuarse de manera óptima a las necesidades de la universidad.
Evaluating a hierarchical approach to landscape level harvest scheduling
2018
Forest planning at the landscape level has the potential to become a large intractable problem. In Finland, Metsähallitus (the state enterprise that manages federally owned land) creates strategic plans to determine the appropriate harvest level. While these plans are feasible, they are not implementable in practice as the harvests are scattered temporally and spatially. Requiring that harvests be organized both temporally and spatially for practical implementation can result in an intractable problem. Through a hierarchical approach, the problem can be organized into steps in which the intractable problem is broken down into smaller easily solvable parts. As an approximation technique, the…
Análisis bibliométrico y sistémico de la relación entre la gestión y el carbono
2022
[EN] This paper aims to present a bibliometric and systemic analysis of the Bibliographic Portfolio (BP) jointly examining the literature related to topics like “Greenhouse gas,” mainly carbon, and “Management,” as published in databases data such as Web of Science and Scopus in the field of economic and social sciences. The Knowledge and Constructivist Development Process methodology —Proknow-C— was used to establish the final portfolio and through the VosViewer program were mapped the various groups or relationships between the studied literature. The paper presents the theoretical and methodological aspects focusing on the areas and countries of study and highlighting the most relevant a…
Conceptual Characterization of Cybersecurity Ontologies
2020
Part 7:Risk and Security Modeling; International audience; Cybersecurity is known as the practice of protecting systems from digital attacks. Organizations are seeking efficient solutions for the management and protection of their assets. It is a complex issue, especially for great enterprises, because it requires an interdisciplinary approach. The kinds of problems enterprises must deal with and this domain complexity induces misinterpretations and misunderstandings about the concepts and relations in question. This article focus on dealing with Cybersecurity from an ontological perspective. The first contribution is a search of previously existing works that have defined Cybersecurity Ont…
