Comparative study of red grape mustnanofiltration: Laboratory and pilot plant scales

Producción CientíficaA consequence of global warming is the early ripening of grapes which promotes, among others, a higher fermentablesugar (glucose and fructose) content. This leads to wines with an alcoholic degree higher than desired.In this work, the main differences between red grape must nanofiltration at laboratory and pilot plant scale werestudied in order to perform the scale-up of a nanofiltration process to reduce the sugar content. For this, previousresults of the nanofiltration of commercial red must using the SR3 membrane in a flat sheet crossflow module werecompared with those obtained for the filtration of natural red must using the same membrane in a spiral woundmodule at two different applied pressures.The aim of this publication is to analyze the main differences between red grape must nanofiltration at laboratoryand at pilot plant scale.Results: showed that the flow destabilization and eddy promotion caused by spacers in the spiral wound modulemitigate the rate at which the cake thickens and compacts on the membrane surface. This causes a less sharp fluxdecrease, less variable sugars rejection and osmotic pressure difference. Moreover, higher applied pressure promotesa higher membrane fouling and osmotic pressure that worsen the flux decayJunta de Castilla y León (programa de apoyo a proyectos de investigación – Ref.

Deposition of Au nanoparticles into mesoporous SiO2 SBA-15

Au/SiO2 SBA-15 materials were prepared using supercritical CO2 (scCO2) and by wet impregnation. First, SiO2 SBA-15 was functionalized with thiol groups at different grafting densities using 3-(Mercaptopropyl)trimethoxysilane dissolved in scCO2. The support was then impregnated with HAuCl4·3H2O in scCO2 modified with EtOH. Wet impregnation of the supports with HAuCl4·3H2O in ethanol was also performed. Materials were calcined at 500 ºC to remove the organic matter and promote particle growth. Materials prepared on the highest thiol grafting density support showed Au NP between 2.5-5 nm homogeneously distributed within the mesopores. Slightly larger Au NPs were obtained in scCO2 modified with EtOH. Materials prepared on the low thiol grafting density support showed a bimodal particle size distribution with particles up to 7 nm located inside the mesopores and larger ones of 10-20 nm on the external surface. A possible reaction mechanism was proposed. These materials can be used in catalysis, sensing and biomedicine

Indicadores de comportamiento de la competencia de innovación en el ámbito académico y en el profesional: revisión de la literatura

[EN] Companies pay more and more attention to the innovation competence of their employees. Innovation is understood as either the introduction of something such as a product, service, process or method, completely new, or the improvement of something that already exists. This paper presents the work performed by the research group IEMA-UPV so as to improve the INCODE barometer (from their previous European project “Innovation Competencies Development”), to be used by both companies and universities. This barometer has been adopted and will be refined in the framework of their new European project FINCODA (“Framework for Innovation Competencies Development and Assessment”) as a tool to measure and assess the behavioral indicators of the innovation competence, which are being identified through a systematic literature review. As a part of the research being performed, this paper also introduces the new model established by the FINCODA project. In this model, the innovation competence is presented as a cluster with three dimensions: creativity, critical thinking and the third one, intrapreneurship, which includes three sub-dimensions (initiative, teamwork and networking).[ES] Las empresas valoran cada vez más la competencia de innovación de sus empleados, entendiendo por innovación la introducción de algo (producto, servicio, proceso o método) completamente nuevo o también la mejora de algo que ya existe. Este trabajo presenta el trabajo realizado por el grupo de investigación IEMA-UPV para la mejora del barómetro INCODE (de su proyecto europeo anterior “Innovation Competencies Development”), y la utilización de este tanto en la empresa como en la universidad. Este barómetro ha sido adoptado y será mejorado en el marco de su nuevo proyecto europeo FINCODA (“Framework for Innovation Competencies Development and Assessment”) como instrumento para medir y evaluar los indicadores del comportamiento de la competencia de innovación, que están siendo identificados como resultado de una revisión sistemática de la literatura. Como parte de la investigación que se está realizando, en este trabajo se presenta, asimismo, el nuevo modelo establecido por el proyecto FINCODA, en el que la competencia de innovación se muestra como un conjunto en el que se encuentran integradas tres dimensiones: creatividad, pensamiento crítico y una tercera, intraemprendedurismo, que incluye tres sub-dimensiones (iniciativa, trabajo en equipo y trabajo en red).Este trabajo ha sido financiado con el Proyecto Erasmus+ Project FINCODA, Framework for Innovation Competences Development and Assessment_554493-EPP-1-2014-1-FIEPPKA2-KA (The European Commission support for the production of this publication does not constitute an endorsement of the contents which reflects the views only of the authors, and the Commission cannot be held responsible for any use which may be made of the information contained therein) y el Proyecto PIME 2015-2016 A/09_Evaluación de los indicadores del comportamiento innovador en el alumno universitario, de la Universitat Politècnica de València.Aznar Más, L.; Pérez Peñalver, MJ.; Montero Fleta, MB.; González Ladrón De Guevara, FR.; Marín García, JA.; Atarés Huerta, LM.

Proposal of a Framework for Innovation Competencies Development and Assessment (FINCODA)

[EN] In this article we propose a model of innovation competence of people, based on the existing literature to integrate and complement the existing models. The main contribution of this work consists in demonstrating the differences and similarities of current models and in providing a conceptual definition for each model element. In this way, both researchers and people in charge of Human Resources in companies can obtain a framework to design measuring instruments to assess the innovation competence, which can fulfil the twofold demand requirement of validity and reliability.This work has been conducted as part of a European project financed by the European Union ["FINCODA" Project 554493-EPP-1-2014-1-FI-EPPKA2-KA] (http://bit.ly/FINCODA-EUsite01).

Healthcare workers hospitalized due to COVID-19 have no higher risk of death than general population. Data from the Spanish SEMI-COVID-19 Registry

Aim To determine whether healthcare workers (HCW) hospitalized in Spain due to COVID-19 have a worse prognosis than non-healthcare workers (NHCW). Methods Observational cohort study based on the SEMI-COVID-19 Registry, a nationwide registry that collects sociodemographic, clinical, laboratory, and treatment data on patients hospitalised with COVID-19 in Spain. Patients aged 20-65 years were selected. A multivariate logistic regression model was performed to identify factors associated with mortality. Results As of 22 May 2020, 4393 patients were included, of whom 419 (9.5%) were HCW. Median (interquartile range) age of HCW was 52 (15) years and 62.4% were women. Prevalence of comorbidities and severe radiological findings upon admission were less frequent in HCW. There were no difference in need of respiratory support and admission to intensive care unit, but occurrence of sepsis and in-hospital mortality was lower in HCW (1.7% vs. 3.9%; p = 0.024 and 0.7% vs. 4.8%; p<0.001 respectively). Age, male sex and comorbidity, were independently associated with higher in-hospital mortality and healthcare working with lower mortality (OR 0.211, 95%CI 0.067-0.667, p = 0.008). 30-days survival was higher in HCW (0.968 vs. 0.851 p<0.001). Conclusions Hospitalized COVID-19 HCW had fewer comorbidities and a better prognosis than NHCW. Our results suggest that professional exposure to COVID-19 in HCW does not carry more clinical severity nor mortality

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality
