Incidence of grapevine leafroll associated viruses -1, -2, and -3 in Mendoza vineyards

Indexación: ScieloViticulture is important in Argentina's economy, especially in the province of Mendoza, which is responsible for more than 75% of the crop cultivated area. In this work, we evaluated the incidence of Grapevine leafroll-associated viruses (GLRaV) -1, -2, and -3 in Vitis vinifera clones of cultivars Cabernet Sauvignon, Cabernet Franc, and Sauvignon Blanc, planted in different zones of Mendoza. The selected clones were previously reported as putatively infected by GLRaV-2. All selected samples were analyzed by DAS-ELISA for GLRaV-1,-2 and -3. GLRaV-2 was the only virus identified in all the analyzed clones. The overall infection rates were 0.6%, 18.8% and 1.2 % for GLRaV-1, 2 and 3 respectively. For the clone Cabernet Sauvignon 337, the infection rate was very high (68.3%).http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1982-56762010000600007&nrm=is

Ideas for the Provision of Ontology Access in Grid Environments

Ontologies are the backbone of the Semantic Web. Current grid architectures do not consider their usage, and there are no protocols nor standards in the Grid community for dealing with them. Therefore, the provision of appropriate means for accessing, querying and using ontologies effectively is a key factor if we want to enrich the current grid with semantic technologies and to support progress towards the next generation Grid, that is, the Semantic Grid

Executing Evaluations over Semantic Technologies using the SEALS Platform

The SEALS European project aims to develop an infrastructure for the evaluation of semantic technologies. This paper presents in detail the approach followed to automate the execution of these evaluations in the infrastructure. To materialize this approach, we have dened the entities managed by the infrastructure and their life cycle, the process followed to execute evaluations, the management of the computing resources that form the execution infrastructure, and how tools can be integrated with the infrastructure

Towards an Infrastructure for the Evaluation of Semantic Technologies

This paper presents and discusses the current development status of the SEALS Platform, a lasting reference infrastructure for semantic technology evaluation. It describes the different entities managed by the platform and the ontology-based model that has been defined to represent them; it also provides an overview of the platform architecture. In addition, it presents the different challenges faced during the development of the SEALS Platform and a use scenario of the platform that supports the execution of evaluation campaigns over semantic technologies

Micosis Fungoide en un perro

Se describe un caso de Micosis Fungoide (MF) en un perro mestizo de 10 años de edad. El animal presentaba una dermatosis multifocal prurítica y simétrica que afectaba a la cabeza, abdomen, ingles, axilas y membranas mucosas., Las principales lesiones eran eritemas, placas, pápulas, pústulas y ulceraciones. Inicialmente se sospechó un pénfigo vulgaris pero los estudios histopatológícos y el test de inmunofluorescencia directa (negativo) evidenciaron que se trataba de una MF.We describe a case of Mycosis Fungoides (MF) in a 10 years old mixed-breed dog. The animal showed a pruritic multifocal dermatosis which affected bead, abdomen, axillae, groins and mucous membranes. Main lesions inciuded erytherna, plaques; papuies, pus tules and ulceration. First a pemphigus vulgaris was suspeaed but histopathology and direct immunofluorescence testing (negative) showed that it was a M.F

On the strong discontinuity approach in finite deformation settings

Taking the strong discontinuity approach as a framework for modelling displacement discontinuities and strain localization phenomena, this work extends previous results in infinitesimal strain settings to finite deformation scenarios. By means of the strong discontinuity analysis, and taking isotropic damage models as target continuum (stress–strain) constitutive equation, projected discrete (tractions–displacement jumps) constitutive models are derived, together with the strong discontinuity conditions that restrict the stress states at the discontinuous regime. A variable bandwidth model, to automatically induce those strong discontinuity conditions, and a discontinuous bifurcation procedure, to determine the initiation and propagation of the discontinuity, are briefly sketched. The large strain counterpart of a non-symmetric finite element with embedded discontinuities, frequently considered in the strong discontinuity approach for infinitesimal strains, is then presented. Finally, some numerical experiments display the theoretical issues, and emphasize the role of the large strain kinematics in the obtained result

Experiencia con un repositorio de ejercicios de programación en un campus virtual: de una colección de libre acceso a otra guiada por la progresión del estudiante

El Campus Virtual es el entorno en el que se ha implementado una Virtualización de Casos Prácticos para facilitar el aprendizaje activo de la materia “Introducción a la programación” en la Universidad Complutense de Madrid. El carácter multidisciplinar de esta colección de casos prácticos los hace útiles en diversas titulaciones de la citada universidad. En este artículo se presenta la evolución que ha experimentado la Virtualización de Casos Prácticos, desde una colección de libre acceso a contenidos hasta la actual con un acceso controlado por la progresión del estudiante.Peer Reviewe

Silicon-based three-dimensional microstructures for radiation dosimetry in hadrontherapy

In this work, we propose a solid-state-detector for use in radiation microdosimetry. This device improves the performance of existing dosimeters using customized 3D-cylindrical microstructures etched inside silicon. The microdosimeter consists of an array of micro-sensors that have 3D-cylindrical electrodes of 15 μm diameter and a depth of 5 μm within a silicon membrane, resulting in a well-defined micrometric radiation sensitive volume. These microdetectors have been characterized using an 241Am source to assess their performance as radiation detectors in a high-LET environment. This letter demonstrates the capability of this microdetector to be used to measure dose and LET in hadrontherapy centers for treatment plan verification as part of their patient-specific quality control program
