Migração de analógico para digital da rede sísmica do CIVISA mediante o desenho de um sistema de aquisição de dados e um rádio telemetria Wi-Fi

ABSTRACT: In September of 2016 a new digital communications network for the Azores Civil Protection (SRPCBA) was inaugurated providing digital, voice and Ethernet LAN telemetry capabilities to the Centre for Information and Seismovolcanic Surveillance of the Azores (CIVISA). During 2017, the telemetry links from all monitoring techniques were reconnected to the new communication system. In 2018 the CIVISA has started the migration from analogue to digital seismic stations and this process allow to liberate few short period geophones. At the CIVISA’s Information and Communication Technologies Support group (SATIC), motivated by the availability of sensors, an instrumentation project was started with the objective of develop affordable digital data acquisition system (DAS) for geophones and a Wi-Fi telemetry to transmit seismic data to the Data Acquisition Centre (CAD) of CIVISA, in Ponta Delgada. The DAS design uses Do It Yourself (DIY) modules for Internet of Things (IoT) applications, microcontrollers and low power computer boards.RESUMO: Em setembro de 2016, foi inaugurada uma nova rede de comunicações digitais para o Serviço Regional de Proteção Civil e Bombeiros dos Açores (SRPCBA), fornecendo capacidades de telemetria digital e voz ao Centro de Informação e Vigilância Sismovulcânica dos Açores (CIVISA). Em 2017, os enlaces de rádio das diversas técnicas de monitorização passaram para o sistema atual. Em 2018, o CIVISA iniciou a migração das estações sísmicas analógicas para digitais e este processo libertou alguns geofones. No grupo de Serviço de Apoio às Tecnologias de Informação e Comunicação (SATIC), motivado pela disponibilidade de sensores, iniciou-se um projeto com o objetivo de desenvolver um instrumento de aquisição de dados acessível (DAS) para geofones e um rádio Wi-Fi para retransmitir dados para o Centro de Aquisição de Dados (CAD), em Ponta Delgada. O DAS utiliza dispositivos Do It Yourself (DIY) para aplicações de Internet de Coisas (IoT) e computadores de baixa potência.info:eu-repo/semantics/publishedVersio

A collaboratively derived environmental research agenda for Galapagos

Galápagos is one of the most pristine archipelagos in the world and its conservation relies upon research and sensible management. In recent decades both the interest in, and the needs of, the islands have increased, yet the funds and capacity for necessary research have remained limited. It has become, therefore, increasingly important to identify areas of priority research to assist decision-making in Galápagos conservation. This study identified 50 questions considered priorities for future research and management. The exercise involved the collaboration of policy makers, practitioners and researchers from more than 30 different organisations. Initially, 360 people were consulted to generate 781 questions. An established process of preworkshop voting and three rounds to reduce and reword the questions, followed by a two-day workshop, was used to produce the final 50 questions. The most common issues raised by this list of questions were human population growth, climate change and the impact of invasive alien species. These results have already been used by a range of organisations and politicians and are expected to provide the basis for future research on the islands so that its sustainability may be enhanced. </jats:p

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Isolation and identification of membrane vesicle-associated proteins in Gram-positive bacteria and mycobacteria

Many intracellular bacterial pathogens naturally release membrane vesicles (MVs) under a variety of growth environments. For pathogenic bacteria there are strong evidences that released MVs are a delivery mechanism for the release of immunologically active molecules that contribute to virulence. Identification of membrane vesicle-associated proteins that can act as immunological modulators is crucial for opening up new horizons for understanding the pathogenesis of certain bacteria and for developing novel vaccines. In this protocol, we provide all the details for isolating MVs secreted by either mycobacteria or Gram-positive bacteria and for the subsequent identification of the protein content of the MVs by mass spectrometry. The protocol is adapted from Gram-negative bacteria and involves four main steps: (1) isolation of MVs from the culture media; (2) purification of MVs by density gradient ultrucentrifugation; (3) acetone precipitation of the MVs protein content and in-solution trypsin digestion and (4) mass spectrometry analysis of the generated peptides and protein identification. Our modifications are: • Growing Mycobacteria in a chemically defined media to reduce the number of unrelated bacterial components in the supernatant. • The use of an ultrafiltration system, which allows concentrating larger volumes. • In solution digestion of proteins followed by peptides purification by ziptip

Tests of CMS Hadron Forward Calorimeter Upgrade Readout Box Prototype

A readout box prototype for CMS Hadron Forward calorimeter upgrade is built and tested in CERN H2 beamline. The prototype is designed to enable simultaneous tests of different readout options for the four anode upgrade PMTs, new front-end electronics design and new cabling. The response of the PMTs with different readout options is uniform and the background response is minimal. Multi-channel readout options further enhance the background elimination. Passing all the electronics, mechanical and physics tests, the readout box proves to be capable of providing the forward hadron calorimeter operations requirements in the upgrade era
