Métodos de trabajo y resultados de refuerzos en madera de un forjado del siglo XVII de la Sacristía de San Miguel en Morón de la Frontera (Sevilla)

During the 20th century numerous solutions for reinforcing wood sub-floors with concrete slabs and frameworks were introduced with the aim of remedying malfunctions due to rheological reasons or the deterioration of some of the components. In certain cases, however, these solutions created an excessive load, and as time went by they aggravated the original pathologies, to the extent where props were required. This is precisely the case of one of the sub-floors in the sacristy that was abutted to the parish church of San Miguel in Morón during the 17th century. The sub-floors on both levels are made of timber beams and hollow plaster bricks. As part of the restoration works carried out in 2013, a concrete slab added for reinforcement in 1970 was removed and replaced with a new reinforcement made out of plywood, pre-tensioning the joints between the new and old pieces. This has significantly reduced the cambers, preserved all the principal elements and led to a more efficient performance. This paper describes the conditions prior to the intervention, the process followed and the results obtained during these restoration works. It also assesses the calculations and projections made.Durante el pasado siglo se pusieron en práctica numerosas soluciones de refuerzo de antiguos forjados de madera mediante losas que pretendían suplir las carencias de funcionamiento por causas reológicas o por deterioro de algunas de sus piezas. Algunas de estas soluciones, sin embargo, supusieron una sobrecarga innecesaria que agravó las patologías previas con el paso del tiempo, hasta el punto de requerir su apuntalamiento. Éste es el caso de uno de los forjados de la sacristía de la parroquia de San Miguel de Morón, un edificio levantado en el transcurso del siglo XVII anexo al templo. Los pisos de sus dos plantas estaban solucionados mediante forjados de vigas de madera y bovedillas de yeso. Como parte de los trabajos de restauración realizados en 2013, se desmontó un refuerzo previo realizado en 1970 mediante losa de hormigón, para ejecutar posteriormente un novedoso tipo de refuerzo con madera laminada, pretensando la unión entre las piezas nuevas y viejas, lo que ha permitido reducir de forma notable las flechas, mantener todos sus elementos principales y obtener un comportamiento más eficiente. La presente aportación expone las condiciones previas a la intervención, el proceso seguido y los resultados obtenidos durante esta restauración valorando los cálculos y previsiones realizadas

OBSERVATORIO TERRITORIAL Y AMBIENTAL ALENTEJO, EXTREMADURA, CENTRO (OTALEX C): DE GIS A IDE.

In the scope of the Spain-Portugal INTERREG projects and FEDER funded POCTEP program, OTALEX C (Territorial and Environmental Monitoring Alentejo Extremadura Center) project aims at studying of various territorial, socioeconomic and environmental indicators. It is the fundamental objective of this project, to develop a geo-portal accessible via internet, for anyone, so that the information will be useful in making decisions related to land use and therefore sustainable development of the environment. Under this general framework over the past fifteen years, we have developed different projects that have set the standardization of data between Portugal and Spain, also was designed GIS systems, and developed regional models and indicator systems, culminating in the current Spatial Data Infrastructure SDI-OTALEX C

Cork : properties, capabilities and applications

Cork is a natural, renewable, sustainable raw material that has been used for many centuries. As a result of this very long term interest, the scientific literature on cork is extensive. The present review focuses on the chemical composition, physical and mechanical properties of cork and on its products and sub-products. The substantial efforts to fully characterise cork, as well as new developments and evolving research, are reviewed, beginning with its histology, growth and morphology (at macro- and microscales). The chemical structure is analysed in detail, covering both the materials that form the wall structure and the low molecular weight, extractable components. The unique properties of cork are discussed and correlated with current knowledge on morphology and chemical structure. Finally, the important industrial applications of cork are reviewed, in the context of research to provide cork with novel, high added-value applications

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

TechnoHeritage: ciencia, tecnología y empresa al servicio del patrimonio cultural

Los avances científicos y tecnológicos que inciden sobre la tutela del patrimonio cultural se producen de forma cada vez más acelerada. Sistemas de auscultación, prospección y análisis de su materialidad, de control de las diversas magnitudes que los caracterizan, o de representación y modelización, han adquirido una dimensión inédita en las últimas décadas. Las tecnologías digitales no sólo mejoran cuantitativa y cualitativamente las posibilidades de aproximación al legado histórico, sino que permiten nuevas formas de interpretar y difundir el patrimonio. Con objeto de abordar esta problemática, se celebrará en Sevilla, en 2019, un congreso que consistirá en un encuentro internacional de investigadores y especialistas de múltiples áreas concernidas por el conocimiento y conservación del patrimonio cultural ¿con varias secciones dedicadas en esta ocasión al patrimonio arquitectónico- y que comparten el uso de tecnologías digitales en sus estrategias metodológicas. Se presentarán trabajos sobre nuevas tecnologías, materiales y productos y se tratarán cuestiones candentes sobre gestión, impacto social, riesgos y vulnerabilidad del patrimonio cultural
