    The holotypes of the Cenozoic fossil wasps attributed to the family Figitidae, which were described in the first half of the 20th century by Charles T. Brues and Georg Statz from Florissant (USA) and Rott-am-Siebengebirge (Germany) sites respectively, have been restudied. The following new taxonomic changes are proposed: Palaeogronotoma? sola (Brues) n. comb., Aulacidea rotundata (Statz) n. comb., A. plana (Statz) n. comb. and A. spiniger (Statz) n. comb. The three last species listed have changed their taxonomic position, as the extant genus Aulacidea belongs to family Cynipidae, not Figitidae as was considered originally in 1938. The revision of one Baltic amber fossil species originally described in 1919, shows that it has a unique set of characters within Cynipidae, allowing the description of a new tribe: Kinseycynipsini n. tribe. Taxonomical comments about other three fossil cynipid species are provided. The correct taxonomical placement of the figitid and cynipid fossil species described ca. one century ago is important for understanding the evolution of these two cynipoid families, which play an important ecological role in the extant terrestrial ecosystems. In addition, updated lists of figitid and cynipid fossil species known are also provided.En la presente investigación se revisan los holotipos de las avispas fósiles del Cenozoico atribuidas a la familia Figitidae, las cuales fueron descritas en la primera mitad del siglo XX por Charles T. Brues y Georg Statz provenientes de los yacimientos de Florissant (EE.UU.) y Rott-am-Siebengebirge (Alemania), respectivamente. Se proponen los siguientes cambios taxonómicos: Palaeogronotoma? sola (Brues) n. comb., Aulacidea rotundata (Statz) n. comb., A. plana (Statz) n. comb. y A. spiniger (Statz) n. comb. Los cambios taxonómicos para las tres últimas especies indicadas han implicado su emplazamiento en el género actual Aulacidea, de la familia Cynipidae, y por lo tanto no pertenecen a la familia Figitidae como se consideró originalmente en 1938. La revisión de una especie fósil originalmente descrita en 1919, conservada en ámbar báltico, muestra que posee un conjunto único de caracteres para la familia Cynipidae, permitiendo la descripción de una nueva tribu: Kinseycynipsini n. tribe. Se hacen indicaciones taxonómicas referidas a otras tres especies de cinípidos fósiles. La adscripción taxonómica correcta de las especies fósiles de figítidos y cinípidos descritas hace alrededor de un siglo es importante para entender la evolución de estas dos familias de cinipoideos, las cuales desempeñan un importante papel ecológico en los ecosistemas terrestres actuales. También se proporcionan listas actualizadas de las especies fósiles de figítidos y cinípidos conocidas

    El proyecto “Cartagena Puerto de Culturas”: un modelo de gestión urbana sostenible basado en la recuperación del patrimonio cultural

    Get PDF
    El bien cultural constituye un modo de identidad social y juega un importante papel en el desarrollo de la economía española. La reflexión sobre la necesidad de intervención en este patrimonio, además de establecer qué y cómo se debe hacer, plantea la necesidad de definir el porqué y para qué como decisions imprescindibles para determinar si es sostenible económicamente su mantenimiento. Nos enfrentamos ante una discusión sobre los modos de integración del patrimonio cultural en el proyecto urbano de ciudad, como elemento regenerador del modelo adoptado de manera que se garantice la sostenibilidad del conjunto. Su anàlisis puede tener dos perspectivas diferentes de acuerdo a su escala.Peer Reviewe

    Merbots project: overal description, multisensory autonomous perception and grasping for underwater robotics interventions

    Get PDF
    [Abstract] The MERBOTS project is, at the moment of writing the present article, in its third year, and have already obtained most of the expected results, from both lab and sea field trials. The project is being coordinated by the Jaume I University (i.e. IRS Lab), jointly with the University of Girona (i.e. CIRS Lab), and University of Balearic Island (i.e. SRV Group). Recent results demonstrate the viability to perform semi-autonomous cooperative interventions in underwater scenarios for archaeological applications. In this paper, first of all an overall description of the project is given, and then some results belonging to the UJI subproject are explained in more detail, such as communications and, in a more detailed manner, the autonomous perception and grasping modules.Ministerio of Economía y Competitividad; DPI2014-57746-C3-1-RGeneralitat Valenciana; GVA-PROMETEO/2016/066Universitat Jaume I; P1-1B2015-6

    Palaeobiology of tanaidaceans (Crustacea: Peracarida) from Cretaceous ambers: extending the scarce fossil record of a diverse peracarid group.

    Diverse assemblages of tanaidacean peracarid crustaceans from western Tethyan continental deposits suggest that the group was relatively common in or around ancient resin-producing forests. Here we report the results of an examination of 13 tanaidacean specimens from three Cretaceous (Albian to Turonian) French amber deposits. Two new species of the fossil family Alavatanaidae are placed in the previously described Early Cretaceous genus Eurotanais: Eurotanais pyrenaensissp. nov. from Cenomanian Pyrenean amber (Fourtou, Aude) and Eurotanais seilacherisp. nov. from Turonian Vendean amber (La Garnache, Vendée). The remaining specimens are placed in three newly erected genera and species (but family incertae sedis): Arcantitanais turpisgen. et sp. nov. from Albian-Cenomanian Charentese amber (Archingeay, Charente-Maritime), and Tytthotanais tenvisgen. et sp. nov. and Armadillopsis raragen. et sp. nov. from Pyrenean amber. These are the first formally described fossils that might be related to the paratanaoidean families Nototanaidae and Paratanaidae, sharing with these some putatively derived features and providing possible evidence for the antiquity and morphological stability of these families and the suborder Tanaidomorpha. The distinctive features and character combinations of these fossil taxa are discussed in connection with possible relationships to the living lineages of tanaidaceans. Propagation phase-contrast X-ray synchrotron microtomography was used to obtain high-quality 3D images for some fossils. A discussion is provided on the putative palaeobiology of tanaidaceans and the French resiniferous forest ecosystem. The discovery of these new tanaidaceans extends the palaeogeographical distribution and stratigraphical range of the family Alavatanaidae and sheds new light on the palaeoecology and diversity of tanaidaceans in pre-angiospermous woodlands

    Education is essential to developing young people’s skills and culture. It is vital that entrepreneurship education is addressed from the secondary education. Entrepreneurship education is essential not only to shape the mindsets of young people but also to provide the skills that are important to developing an entrepreneurial culture. The entrepreneurship key competence refers to an individual’s ability to turn ideas into action. It includes creativity, innovation, and the ability to plan projects in order to achieve objectives. Besides, communication and ICT are relevant in innovation processes in organizations, especially in schools where people interact daily and it is intended to ensure a good future for the organization. In schools, the existence of good communication and the use of ICT is a relevant factor for the integration of teaching innovative projects related to entrepreneurship. A good communication ensures the dissemination of educational innovation processes adopted by the teachers. It´s relevant to improve teaching practice. Communication and the ICT play a key role in the processes of educational innovation. The incorporation of innovative materials, ICT, courses and communication activities, and the use of the media to extract information, are very important. Communication is essential in the secondary education. If the communication flows were eliminated in the school, we would not have school. Communication is introduced into all activities of the school, representing an important tool with which individuals understand their role in the school and integrates organizational departments. The secondary schools are organized through a model based on the participation and collaboration of its component, coordinating the actions of different people in order to achieve the proposed educational objectives. Therefore, the optimal operation of a secondary school is closely related to communication processes taking place in this organization. This paper studies the entrepreneurship, communication processes and the ICT in secondary education. Media and communication channels used in secondary schools to spread the teaching innovation projects related to the entrepreneurship are studied. Supports or conventional tools and new technologies for communication in educational organizations are also analysed when it is studied and worked the entrepreneurship in the classroom.info:eu-repo/semantics/publishedVersio

    ABSTRACT: The dataset presented here is an achievement of the H2020 European project "Integrated Pest Management of the Invasive Japanese Beetle, Popillia japonica (IPM-Popillia)". This project addresses the challenge of a new risk to plant health in Europe, the invasion of the Japanese beetle, Popillia japonica (Newman, 1838) (Coleoptera, Rutelidae) and provides an environmentally friendly IPM Toolbox to control the expanding pest populations across Europe. This study aims to present the records of terrestrial arthropod diversity with a special focus on four groups belonging to Carabids and Staphylinid beetles (Coleoptera), Opiliones and Anisolabididae (Dermaptera), collected with the potential to be used as biocontrol agents against P. japonica in future Integrated Pest Management programmes. A thorough sampling programme was conducted in maize and pasture fields in two Islands of the Azores (São Miguel and São Jorge) in the summer of 2022.info:eu-repo/semantics/publishedVersio

    Fitting primitive shapes in point clouds: a practical approach to improve autonomous underwater grasp specification of unknown objects

    Get PDF
    This article presents research on the subject of autonomous underwater robot manipulation. Ongoing research in underwater robotics intends to increase the autonomy of intervention operations that require physical interaction in order to achieve social benefits in fields such as archaeology or biology that cannot afford the expenses of costly underwater operations using remote operated vehicles. Autonomous grasping is still a very challenging skill, especially in underwater environments, with highly unstructured scenarios, limited availability of sensors and adverse conditions that affect the robot perception and control systems. To tackle these issues, we propose the use of vision and segmentation techniques that aim to improve the specification of grasping operations on underwater primitive shaped objects. Several sources of stereo information are used to gather 3D information in order to obtain a model of the object. Using a RANSAC segmentation algorithm, the model parameters are estimated and a set of feasible grasps are computed. This approach is validated in both simulated and real underwater scenarios.This research was partly supported by Spanish Ministry of Research and Innovation DPI2011-27977-C03 (TRITON Project), by Foundation Caixa Castelló Bancaixa PI-1B2011-17, by Universitat Jaume I PhD grants PREDOC/2012/47 and PREDOC/ 2013/46, and by Generalitat Valenciana PhD grant ACIF/2014/298
