Farming for nature in the Montado: the application of ecosystem services in a results-based model

The Montado is a silvopastoral system with a tree cover of predominantly Quercus suber but also Quercus rotundifolia, where cattle or sheep graze the understory. It occupies more than one million hectares in southern Portugal, and a similar landscape, the Dehesa, covers ca. three million hectares in Spain. These silvopastoral systems can simultaneously benefit the environment and socio-economic activities by providing a bundle of ecosystem services (ESs). However, an ongoing trend of decline in tree density and the covered area is threat-ening such provision. Policies are needed to motivate farmers to secure the ESs that they provide. One possible format is the development of a results-based model (RBM) for agri-environment schemes (AES), implemented under the Common Agricultural Policy. In an RBM, farmers are paid when they deliver specific environmental results (ERs) (e.g. healthy and functional soils), that are linked with the provision of different (and often mul-tiple) ESs. This study defines possible ERs for the Montado and details how these results are linked to the pro-vision of ESs. It then considers management actions that can allow the achievement of these ERs and the costs of these actions. Our methodological approach is based on a transdisciplinary dialogue involving researchers, practitioners (i.e farmers), public authorities and policy makers. The results of the process include the identi-fication of four main ERs: a healthy soil ecosystem, a biodiverse native-Mediterranean pasture, an oak tree layer where regeneration exists (i.e. trees of different ages), and preserved or enhanced landscape elements, for example riparian galleries with vegetation. These ERs increase the supply of provisioning services (e.g. cork production), of regulating services, (e.g. carbon sequestration), and cultural services (e.g. aesthetic inspiration). RBMs allow farmers to use any management practice they choose as the focus is on the results. Nonetheless, to estimate costs we identified 12 potential strategic management practices (and their cost) along with the technical support that farmers would need. We conclude that an RBM could be an affordable solution for public policies in the Montado system, given the limited government budget for supporting AES.info:eu-repo/semantics/publishedVersio

Genome-wide association meta-analyses and fine-mapping elucidate pathways influencing albuminuria

Increased levels of the urinary albumin-to-creatinine ratio (UACR) are associated with higher risk of kidney disease progression and cardiovascular events, but underlying mechanisms are incompletely understood. Here, we conduct trans-ethnic (n = 564,257) and European-ancestry specific meta-analyses of genome-wide association studies of UACR, including ancestry- and diabetes-specific analyses, and identify 68 UACR-associated loci. Genetic correlation analyses and risk score associations in an independent electronic medical records database (n = 192,868) reveal connections with proteinuria, hyperlipidemia, gout, and hypertension. Fine-mapping and trans-Omics analyses with gene expression in 47 tissues and plasma protein levels implicate genes potentially operating through differential expression in kidney (including TGFB1, MUC1, PRKCI, and OAF), and allow coupling of UACR associations to altered plasma OAF concentrations. Knockdown of OAF and PRKCI orthologs in Drosophila nephrocytes reduces albumin endocytosis. Silencing fly PRKCI further impairs slit diaphragm formation. These results generate a priority list of genes and pathways for translational research to reduce albuminuria

The LHCb upgrade I

The LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger than that of the previous running periods. Readout of all detectors into an all-software trigger is central to the new design, facilitating the reconstruction of events at the maximum LHC interaction rate, and their selection in real time. The experiment's tracking system has been completely upgraded with a new pixel vertex detector, a silicon tracker upstream of the dipole magnet and three scintillating fibre tracking stations downstream of the magnet. The whole photon detection system of the RICH detectors has been renewed and the readout electronics of the calorimeter and muon systems have been fully overhauled. The first stage of the all-software trigger is implemented on a GPU farm. The output of the trigger provides a combination of totally reconstructed physics objects, such as tracks and vertices, ready for final analysis, and of entire events which need further offline reprocessing. This scheme required a complete revision of the computing model and rewriting of the experiment's software

The Royal Chapel of National Palace of Sintra: a study of timber elements

Este trabalho foi financiado pelo Concurso Anual para Projetos de Investigação, Desenvolvimento, Inovação e Criação Artística (IDI&CA) 2019 do Instituto Politécnico de Lisboa. Código de referência IPL/2019/TEC-TIMBER_ISELOn-site inspection work in the historical buildings requires a basic scientific knowledge to be conducted with technical and scientific credibility. This need becomes so absolute when the object is the historical heritage of high value. This paper presents the work of inspection and evalu-ation of timber elements held in the tribune of the Royal Chapel of the National Palace of Sintra, Portugal. It was carried out within the scope of a master's dissertation presented to the Higher Institute of Engineering of Lisbon in 2018. This palace is one of the most important Portuguese monuments, having been linked to the national history by many events. The Royal Chapel has several dates of construction and past interventions dated from the thirteenth to the fifteenth cen-turies. The Gothic, Mudejar and Manueline styles are perfectly combined in there. The work consisted in the characterization and structural assessment of tribune´s first floor beams. Inspections took place between January and May 2018. The wood present in most of the structural and secondary elements is coniferous, most of which has been identified as Pinus Syl-vestris, L. The work was carried out in situ by visual inspection and by non-destructive and semi-destructive tests. Water content, drill resistance and penetration resistance were measured. Phys-ical-mechanical properties of the timber members were estimated based on the in-situ measure-ments and the scientific literature. Visual strength grading was also applied to the floor beams. From the results obtained several important information were taken. Report and recommendations were presented as the conclusion of the study.info:eu-repo/semantics/publishedVersio
