Dielectric constant tunability at microwave frequencies and pyroelectric behavior of lead-free submicron-structured (Bi0.5Na0.5)1-xBaxTiO3 ferroelectric ceramics

In this article we show that the dielectric constant of lead-free ferroelectric ceramics based on the solid solution (1-x)(Bi0.5Na0.5)TiO3-xBaTiO3, with compositions at or near the morphotropic phase boundary (MPB), can be tuned by a local applied electric field. Two compositions have been studied, one at the MPB, with x=0.06 (BNBT6), and another one towards the BNT side of the phase diagram, with x=0.04 (BNBT4). The tunability of the dielectric constant is measured at microwave frequencies between 100 MHz and 3 GHz by a non-resonant method and simultaneously applying a DC electric field. As expected, the tunability is higher for the composition at the MPB (BNBT6), reaching a maximum value of 60 % for an electric field of 900 V/cm, compared with the composition below this boundary (BNBT4), which saturates at 40 % for an electric field of 640 V/cm. The high tunability in both cases is attributed to the fine grain and high density of the samples, which have a submicron homogeneous grain structure with grain size of the order of a few hundred nanometers. Such properties make these ceramics attractive for microwave tunable devices. Finally, we have tested these ceramics for their application as infrared pyroelectric detectors and we have found that the pyroelectric figure of merit is comparable to traditional lead containing pyroelectrics.This work was supported by Ministerio de Ciencia e Innovación of Spain (TIN2009-14372-C03-02), Fundación Séneca (15303/PI/10), and CSIC (PIE 201060E069)

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

Definición de una metodología institucional para la gestión de proyectos en una empresa TI

Magíster en Tecnologías de la InformaciónBusinessMind es una compañía con ocho años en el mercado chileno, especializada en brindar servicios de consultoría, outsourcing, capacitación e integración de tecnología. Los proyectos desarrollados por la empresa BusinessMind cubren varios sectores, tales como telecomunicaciones, gobierno, petróleo, retail, financiero, educación e industria en general. La gestión de proyectos de la compañía se llevaba a cabo en base a la experiencia de sus consultores y/o jefes de proyecto. A pesar de que se toma en cuenta la información de proyectos anteriores para la planificación de los proyectos futuros, no existía un modelo formal que permita establecer tiempos, costos y recursos con un bajo índice de error. Esto derivaba en varios riesgos para la empresa, como el desperdicio de recursos, retraso en tiempos de entrega, inconformidad de los clientes y fuga de conocimiento. Todo esto perjudicaba la imagen de la compañía frente a los clientes. Para ayudar a paliar esta situación, el objetivo general de este trabajo de tesis fue definir una metodología institucional para la gestión de proyectos de TI realizados por la empresa BusinessMind. En base a la cultura organizacional de la empresa se definieron y formalizaron los procesos, tareas, productos y actores involucrados en la gestión de proyectos TI. La metodología resultante fue aplicada en dos proyectos de Business Intelligence de corta duración, como prueba de concepto; uno para la empresa BiceVida y el otro para BioSano. Estas pruebas permitieron validar la usabilidad y utilidad de la metodología propuesta, y eventualmente ajustarla en base a los resultados obtenidos. El uso de la metodología mostró mayor visibilidad y control de los proyectos a través de todas las áreas de la empresa, además permitió contar con documentación estandarizada para todos los proyectos implementados por la organización. Por lo tanto, se cumplió con un objetivo estratégico de la empresa, y es actualmente la propuesta representa la metodología base a ser utilizada en otras filiales de BusinessMind en la región. Como trabajo a futuro, se pretende extender esta metodología para que pueda ser utilizada en otros tipos de proyectos y servicios que ofrece la empresa
