Apart from analising his testamentary dispositions, some of the less well-known aspects of his biography will be briefl y studied. This will be done specially trying to clarify his family roots and his role as businessman and member of urban elites in Galicia during the 15th century. Besides, this essay will make reference to some of the litigations in which he, and, above all, his heirs were involved. Finally, the article makes public new documents that allow to reconstruct the last moments and wills of Lope Gómez de MarzoaS

    This paper presents the design and simulation of a monolithic high linearity amplifier in GaAs high electron- mobility transistor technology for the S and UHF bands. A specific topology has been chosen in order to achieve a high OIP3 value as well as good input and output return losses. Due to the wide bandwidth of operation an off-chip matching network has been adopted for each operation band. An on-chip active matching circuit has also been included in order to simplify the passive matching network configuration. A gain of approximately 19 dB has been achieved in simulation, as well as good values of input/output matching. The output third order intermodulation point takes a value of 29.3 dBm in the UHF band and 27.4 dBm in the S-band

    Isotopic H/D exchange on graphenes. A combined experimental and theoretical study

    [EN] Adsorption of H-2/D-2 on graphene (G), graphene oxide (GO), single walled carbon nanotube (SWCNT), N-doped graphene [(N)G], and a sample of active carbon (C) has led to the detection of HD, indicating dissociative chemisorption of hydrogen on the surface of the material. The amount of HD detected follows the order G > SWCNT > GO similar to (N)G similar to C, G giving about five-fold higher H-2/D-2 adsorption and HD exchange level than SWCNT and about ten-fold larger values than that of the other samples. Quantum-chemistry calculations modeling a carbon atom vacancy on a G cluster estimates an activation barrier for H-2 dissociation of ca. 84 kJ/mol for a mechanism involving under coordinated carbon atoms at the defect site.Financial support by the Spanish Ministry of Economy and Competitiveness (Severo Ochoa SEV-2016-0267 and CTQ2015-69153-C2-R1) and Generalitat Valenciana (Prometeo 2013/014) is gratefully acknowledged.

    La imagen que el profesor tiene de los alumnos y la aceptación de los alumnos por sus iguales en primero de primaria

    Comunicación presentada en las I Congreso Internacional sobre Ciudadanía Crítica y Mejora Educativa: recursos, estrategias y experiencias, celebradas en la Universitat Jaume I (Castellón, España) los días 13 al 15 de octubre 2011El presente trabajo estudia la relación entre la imagen del alumno que tiene el profesor y la aceptación de los alumnos por sus iguales. La muestra está formada por 247 alumnos escolarizados en 11 aulas de primero de primaria, de cinco colegios públicos de Castellón de la Plana. A nivel metodológico se ha realizado un estudio de correlaciones, el procedimiento Anova de un factor, un análisis de tablas de contingencia r, y un análisis de regresión. Respecto a los resultados, las correlaciones son significativas, el Anova de un factor muestra que el profesor establece claras diferencias entre tipologías sociométricas y el análisis de regresión refleja cierto carácter predictivo de la variable preferencia del maestro sobre la aceptación de los iguales

    Comunicación presentada en las I Congreso Internacional sobre Ciudadanía Crítica y Mejora Educativa: recursos, estrategias y experiencias, celebradas en la Universitat Jaume I (Castellón, España) los días 13 al 15 de octubre 2011.El artículo trata sobre la implementación de un programa multinivel, multicomponente y multiagente. Se aplicó a 4 colegios de Castellón en las aulas de 1º de primaria (curso 2010-2011). Se basa en 3 grandes componentes (normas de convivencia y estrategias permanentes, aprendizaje cooperativo y desarrollo socioemocional) a partir de los cuales se capacitó a los profesores durante 6 sesiones de formación (30 horas). Ellos mismos fueron los que implementaron el programa adaptándolo al currículo, por lo que se pudo observar mejoras considerables, por una parte, aprendieron a ser más conscientes en la forma de dirigirse al alumnado; y por otra, en las relaciones interpersonales con su clase y entre los propios alumnos

    New Tools for Embryo Selection: Comprehensive Chromosome Screening by Array Comparative Genomic Hybridization

    The objective of this study was to evaluate the usefulness of comprehensive chromosome screening (CCS) using array comparative genomic hybridization (aCGH). The study included 1420 CCS cycles for recurrent miscarriage (n = 203); repetitive implantation failure (n = 188); severe male factor (n = 116); previous trisomic pregnancy (n = 33); and advanced maternal age (n = 880). CCS was performed in cycles with fresh oocytes and embryos (n = 774); mixed cycles with fresh and vitrified oocytes (n = 320); mixed cycles with fresh and vitrified day-2 embryos (n = 235); and mixed cycles with fresh and vitrified day-3 embryos (n = 91). Day-3 embryo biopsy was performed and analyzed by aCGH followed by day-5 embryo transfer. Consistent implantation (range: 40.5–54.2%) and pregnancy rates per transfer (range: 46.0–62.9%) were obtained for all the indications and independently of the origin of the oocytes or embryos. However, a lower delivery rate per cycle was achieved in women aged over 40 years (18.1%) due to the higher percentage of aneuploid embryos (85.3%) and lower number of cycles with at least one euploid embryo available per transfer (40.3%). We concluded that aneuploidy is one of the major factors which affect embryo implantation

    COVID-19 vaccine effectiveness against hospitalization due to SARS-CoV-2: A test-negative design study based on Severe Acute Respiratory Infection (SARI) sentinel surveillance in Spain

    Get PDF
    Background: With the emergence of SARS-CoV-2, influenza surveillance systems in Spain were transformed into a new syndromic sentinel surveillance system. The Acute Respiratory Infection Surveillance System (SiVIRA in Spanish) is based on a sentinel network for acute respiratory infection (ARI) surveillance in primary care and a network of sentinel hospitals for severe ARI (SARI) surveillance in hospitals. Methods: Using a test-negative design and data from SARI admissions notified to SiVIRA between January 1 and October 3, 2021, we estimated COVID-19 vaccine effectiveness (VE) against hospitalization, by age group, vaccine type, time since vaccination, and SARS-CoV-2 variant. Results: VE was 89% (95% CI: 83-93) against COVID-19 hospitalization overall in persons aged 20 years and older. VE was higher for mRNA vaccines, and lower for those aged 80 years and older, with a decrease in protection beyond 3 months of completing vaccination, and a further decrease after 5 months. We found no differences between periods with circulation of Alpha or Delta SARS-CoV-2 variants, although variant-specific VE was slightly higher against Alpha. Conclusions: The SiVIRA sentinel hospital surveillance network in Spain was able to describe clinical and epidemiological characteristics of SARI hospitalizations and provide estimates of COVID-19 VE in the population under surveillance. Our estimates add to evidence of high effectiveness of mRNA vaccines against severe COVID-19 and waning of protection with time since vaccination in those aged 80 or older. No substantial differences were observed between SARS-CoV-2 variants (Alpha vs. Delta).The data of the study was originally collectedas part of the following projects run by the European Centre for Disease Prevention and Control:“Establishing Severe Acute Respiratory Infections (SARI) surveillance and performing hospital-based COVID-19 transmission studies”, “Developing an infrastructure and performing vaccine effectiveness studies for COVID-19 vaccines in the EU/EEA”, and the “Vaccine Effectiveness, Burden and Impact Studies(VEBIS) of COVID-19 and Influenza".S
