Magnetic and superconducting phase diagrams in ErNi2B2C

We present measurements of the superconducting upper critical field Hc2(T) and the magnetic phase diagram of the superconductor ErNi2B2C made with a scanning tunneling microscope (STM). The magnetic field was applied in the basal plane of the tetragonal crystal structure. We have found large gapless regions in the superconducting phase diagram of ErNi2B2C, extending between different magnetic transitions. A close correlation between magnetic transitions and Hc2(T) is found, showing that superconductivity is strongly linked to magnetism.Comment: 5 pages, 4 figure

Continuous spectra in high-harmonic generation driven by multicycle laser pulses

We present observations of the emission of XUV continua in the 20-37 eV region by high harmonic generation (HHG) with $4$-$7\ \mathrm{fs}$ pulses focused onto a Kr gas jet. The underlying mechanism relies on coherent control of the relative delays and phases between individually generated attosecond pulse, achievable by adjusting the chirp of the driving pulses and the interaction geometry. Under adequate negative chirp and phase matching conditions, the resulting interpulse interference yields a continuum XUV spectrum, which is due to both microscopic and macroscopic (propagation) contributions. This technique opens the route for modifying the phase of individual attosecond pulses and for the coherent synthesis of XUV continua from multicycle driving laser pulses without the need of an isolated attosecond burst.Comment: 14 pages, 5 figures.

Reciclado de Residuos de la Minería del Granito y de Incineradora de RSU en la Obtención de Nuevos Materiales Tipo Gres Porcelánico

In the 1980s started in the ceramic sector the material conception of porcelainized stoneware, a product with versatile and modern characteristics similar to those of the natural stone, depicting improved properties to the marble and granite. Porcelanized stoneware is a compact ceramic material, very hard and homogeneous, generally not fully vitreous (unglazed) in its surface, obtained by fast firing from compositions enriched in kaolinite, which contain a large quantity of fluxes. The raw materials for body are a mixture that contains an adequate relationship of kaolinitic clays, feldspars and quartz. Such material is characterized by its low or almost zero porosity, being adequated to sustain heavy and high traffic intensity for uses in and outside of buildings with wide range of aspects, desings and colors. By considering the chemistry and mineralogical composition of the granite and incinerator wastes, this paper describes their use in the processing of construction materials, specifically, in a new type of stoneware flooring and covering materials. According to the most of the physical and mechanical properties here determined, these "Modified Porcelainized Stoneware" (MPS) materials are close to the conventional porcelainized stoneware and glass ceramics products.Hacia la década de los años 80 se inicia en el sector cerámico la concepción del gres porcelánico, material de características modernas y versátiles semejantes a las de la piedra natural, pero que incluso supera en utilidad y prestaciones al mármol y al granito. El gres porcelánico es un material cerámico compacto, muy duro y homogéneo, no vidriado en su superficie, obtenido por cocción rápida de composiciones ricas en caolinita y una gran cantidad de fundentes; es decir, de una mezcla cerámica que contiene una relación adecuada de arcillas de tipo caolinítico, feldespatos y cuarzo. Dicho material se caracteriza por su baja o casi nula porosidad; es ideal para soportar tráfico pesado y alto tránsito, para usos en interiores y exteriores, con una variedad muy extensa de aspectos diseños y colores. En razón de la composición química y mineralógica de los residuos de granito y de incineradoras de residuos sólidos urbanos (RSU) se planteó determinar su aprovechamiento en la obtención de materiales de construcción, específicamente, en revestimientos y pavimentos de gres porcelánico. Los resultados han revelado la viabilidad de estos residuos en cuanto a su aprovechamiento en la obtención de nuevos materiales tipo gres porcelánico ó "Gres Porcelánico Modificado" (GPM). De acuerdo con algunas de sus propiedades, éstos se sitúan en el margen de los materiales de gres porcelánico y vitrocerámicos clásicos

Fibroma cemento-osificante gingival mandibular: presentación de un caso

Presentamos el caso clínico de una mujer con un fibroma cemento- osificante gigante dependiente de la encía mandibular de 20 años de evolución. El fibroma cemento-osificante es un tumor poco frecuente, clasificado dentro de las lesiones fibroóseas. Aparece generalmente en hueso y en raras ocasiones afecta a tejidos gingivales, como ocurre en nuestro caso. Es una neoplasia de crecimiento lento y bien delimitada, lo que le confiere un carácter benigno. Con los hallazgos histológicos es difícil diferenciar el fibroma cemento-osificante de otras lesiones tales como el osteoblastoma, el osteosarcoma de bajo grado y particularmente de la displasia fibrosa. Para obtener un diagnóstico preciso es fundamental guiarnos además por la información clínica y radiológica y así llevar a cabo un tratamiento oportuno, que condicione un pronóstico excelente.We report a case of a woman presenting a giant cementoossifying fibroma depending of the mandibular gingivae. The evolution of the process was 20 years. Cemento-ossifying fibroma is a relatively rare tumour classified between fibroosseous lesions. This lesion appears within the bone although in some occasions it involves the gingivae soft tissues, as the case we present. It is a slow-growing and well-defined tumorous lesion, because of this, it is considered as a benign lesion. The histologic findings alone may be similar to other pathologies such as osteoblastoma, low-grade osteosarcoma and particularly to fibrous dysplasia. An accurate diagnosis requires careful clinical, radiological and histological correlation in order to make an optimal treatment and an excellent outcome

Active methodologies for deep learning in sustainable development goals

[EN] The general objective of this project was to improve the quality of student learning, from the point of view of a global objective, sustainable development, and therefore aligned with the SDGs (Sustainable Development Goals). It is intended that students achieve deep learning in this area, favouring the transfer of the knowledge acquired to their future professional and social life. This deep learning promotes the integral development of the student, not only from an academic point of view, but also social and ecological. Project Based Learning (PBL), as an active learning methodology, is being widely used as a deep learning strategy. In this project, it has been used in several subjects, from different degrees, schools, and campus. The learning strategies have been evaluated by means of a learning evaluation questionnaire (CEVEAPEU) before and after the application of the PBL. In addition, student satisfaction and generic skills (i.e. ethical, environmental and professional responsibility) have been assessed. The project aims to find a solution a specific real case, such as an environmental or social problem. The results show that PBL has favoured the cooperative work of students and has increased their motivation. The students could select the topics that interest them the most and that they consider important in their professional future. They have worked collaboratively and actively, planning the project, making decisions, implementing it, and evaluating it. The students have ¿acted¿ and the teachers have been advisors or guides, thus promoting intrinsic motivation. This active methodology has allowed students to learn in a collaborative and cooperative way, fostering their motivation and achieving deep learning in environmental aspects.The project of innovation and educational improvement in which this communication is framed has received financial support from the Institute of Education Sciences (ICE) of the Universitat Politècnica de València (UPV) Proyecto de Innovación y Mejora Educativa (PIME/19-20/174 ), Objetivo Agenda 2030 y UPV 2020: Aprendizaje ambiental profundo en la UPV.Romero Gil, I.; Paches Giner, MAV.; Sebastiá-Frasquet, M.; Hernández Crespo, C.

Effectiveness and Efficiency of Drug Eluting Stents

Coronary artery disease (CAD), also known as ischemic heart disease (IHD) and coronary heart disease (CHD), is caused by the narrowing (stenosis) of one or more coronary arteries, due to atherosclerosis, restricting blood flow and reducing the supply of oxygen to the heart muscle. Transient shortages in blood flow and oxygen lead to angina pectoris and chest pain, which may radiate to the left shoulder, arms, neck, back or jaw. Stable angina symptoms do not tend to progress in intensity over time. More seriously, the rupturing of an atherosclerotic plaque (causing a thrombotic occlusion) and stenosis of the vessel can result in acute myocardial infarction (AMI) due to a critical reduction in the blood supply to the heart muscle (myocardial ischemia). High levels of morbidity and mortality associated with this infarction are a consequence of ischemia. It is vital to promptly re-establish coronary blood flow after an infarction, because sustained ischemic damages and injuries to the heart muscle may lead to sudden death or heart failure. In addition to infarction, acute symptomatic manifestations of ischemic heart disease include unstable angina, and less common conditions such as cardiogenic shock and sudden death (Thygesen, 2007)..

The whole genome sequence of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), reveals insights into the biology and adaptive evolution of a highly invasive pest species

31 p.-11 fig.-2 tab.+ Erratum (2 p.) Papanikolaou, Alexie et al.Background: The Mediterranean fruit fly (medfly), Ceratitis capitata, is a major destructive insect pest due to its broad host range, which includes hundreds of fruits and vegetables. It exhibits a unique ability to invade and adapt to ecological niches throughout tropical and subtropical regions of the world, though medfly infestations have been prevented and controlled by the sterile insect technique (SIT) as part of integrated pest management programs (IPMs). The genetic analysis and manipulation of medfly has been subject to intensive study in an effort to improve SIT efficacy and other aspects of IPM control.Results: The 479 Mb medfly genome is sequenced from adult flies from lines inbred for 20 generations. A highquality assembly is achieved having a contig N50 of 45.7 kb and scaffold N50 of 4.06 Mb. In-depth curation of more than 1800 messenger RNAs shows specific gene expansions that can be related to invasiveness and host adaptation, including gene families for chemoreception, toxin and insecticide metabolism, cuticle proteins, opsins, and aquaporins. We identify genes relevant to IPM control, including those required to improve SIT.Conclusions: The medfly genome sequence provides critical insights into the biology of one of the most serious and widespread agricultural pests. This knowledge should significantly advance the means of controlling the size and invasive potential of medfly populations. Its close relationship to Drosophila, and other insect species important to agriculture and human health, will further comparative functional and structural studies of insect genomes that should broaden our understanding of gene family evolutionSupport of this project was provided by the U.S. Department of Agriculture(USDA), Agricultural Research Service (ARS), Animal and Plant Health Inspection Service (APHIS), and National Institute of Food and Agriculture(NIFA)-Biotechnology Risk Assessment Grants Program (grant #2011-39211-30769 to AMH) for funding the initial phase of this project, and to the National Institutes of Health (NIH)-National Human Genome Research Institute (NHGRI) for funding the medfly genome sequencing, assembly and Maker 2.0 automated annotation as part of the i5K 30 genome pilot project (grant #U54 HG003273 to RAG).

Una Herramienta para el Aprendizaje del Álgebra Relacional

El estudio de las bases de datos relacionales forma parte del currículum de los estudios de Ingeniería Técnica Informática. Los lenguajes de consulta abstractos, entre ellos el Álgebra Relacional, forman una parte importante de este estudio, pero nuestra experiencia docente nos ha demostrado que, para los alumnos, es difícil conocer cuándo las consultas expresadas en un papel en términos de estos lenguajes son correctas y responden a los requisitos de información planteados. En este trabajo se describe una herramienta de apoyo que se ha desarrollado en la Universidad de Valladolid que permite realizar consultas expresadas en Álgebra Relacional sobre cualquier base de datos. El alumno puede explorar, así, las diferentes posibilidades de este lenguaje abstracto, comprobando por sí mismo la calidad de su aprendizaje. La herramienta ha sido desarrollada siguiendo guías metodológicas propugnadas en el ámbito del diseño de entornos de aprendizaje
