European guidelines on chronic mesenteric ischaemia - joint United European Gastroenterology, European Association for Gastroenterology, Endoscopy an…

2020

Chronic mesenteric ischaemia is a severe and incapacitating disease, causing complaints of post-prandial pain, fear of eating and weight loss. Even though chronic mesenteric ischaemia may progress to acute mesenteric ischaemia, chronic mesenteric ischaemia remains an underappreciated and undertreated disease entity. Probable explanations are the lack of knowledge and awareness among physicians and the lack of a gold standard diagnostic test. The underappreciation of this disease results in diagnostic delays, underdiagnosis and undertreating of patients with chronic mesenteric ischaemia, potentially resulting in fatal acute mesenteric ischaemia. This guideline provides a comprehensive overvi…

The Italian Society of Gastroenterology (SIGE) and the Italian Group for the study of Inflammatory Bowel Disease (IG-IBD) Clinical Practice Guideline…

2010

Biological therapies are an important step in the management of Inflammatory Bowel Diseases. In consideration of high cost and safety issues there is the need to have clear recommendations for their use. Despite the American Gastroenterological Association and the European Crohn's and Colitis Organisation have published exhaustive Inflammatory Bowel Disease guidelines, national guidelines may be necessary as cultural values, economical and legal issues may differ between countries. For these reasons the Italian Society of Gastroenterology and the Italian Group for the study of Inflammatory Bowel Disease have decided to elaborate the Italian guidelines on the use of biologics in Inflammatory…

Development and implementation of a selective change-driven vision sensor for high speed movement analysis

2013

Un sistema de vision artificial esta compuesto, en su forma más basica, por un sensor VLSI, habitualmente fabricado en tecnología CMOS o CCD, y una etapa de procesado. En la gran mayoría de los sistemas de visión artificial implementados hoy en día la etapa sensora del sistema consiste en un sensor de imágenes tradicional. Este tipo de sensores trabajan bajo unos principios muy simples y conocidos: el nivel de iluminación del entorno es muestreado y transmitido a intervalos de tiempo regulares; y todos los píxeles de la matriz, sin excepción, son transmitidos secuencialmente y en orden. Esto es así aunque no se hayan producido cambios en la escena bajo observación. Esto implica que una gran…

Diseño, caracterización y propuestas de aplicación de sensores GMR (Giant MagnetoResistance) en medida de corriente a nivel de circuito integrado

2013

El efecto MagnetoRresistivo Gigante (GMR) es un mecanismo de acoplo magnético que se da en estructuras multicapa con espesores de nanómetros. En estos dispositivos, la resistencia varía con la aplicación de un campo magnético externo en unos niveles que permiten su uso como sensores, incluso a temperatura ambiente. Es tal la utilidad de los dispositivos basados en GMR, que sus descubridores fueron galardonados con el Premio Nobel de Física en 2007. La constante evolución que está experimentando esta tecnología está abriendo nuevos campos de aplicación, principalmente relacionados con la medida de pequeños campos magnéticos mediante micro y nano-dispositivos, como la biotecnología y la micro…

El sindicato en la microempresa y la pequeña empresa

2016

La infra representación de los trabajadores en las pequeñas empresas y microempresas es una realidad que obedece a una serie de causas legales y de organización y credibilidad sindical y que, por desgracia, ocasiona graves situaciones de desamparo a ingentes cantidades de trabajadores. Se hace necesario pues, un aumento de la representatividad en estas empresas y, dado que hoy por hoy es una utopía esperar cambios legislativos en esa dirección, se debe ahondar –y ese es el fin de este trabajo– en las posibilidades que ofrece nuestro ordenamiento jurídico –sobre todo, desde el prisma de la libertad sindical– para extraer todas las oportunidades que nos conduzcan a ese fin. Para ello, se debi…

Chemical composition and microencapsulation suitability of sumac (Rhus coriaria L.) fruit extract

2021

Sumac (Rhus coriaria L.), a spice obtained by grinding whole sumac berries, is a complex natural product with a plethora of biological activities that can be favorably explored in nutraceutical and pharmaceutical fields. Sicilian sumac is herein chemically investigated by means of a combined NMR/HR MS-based profiling. A hydroalcoholic extract was prepared and its complexity unraveled following fractionation in an alcoholic and an aqueous fraction. The 1H-NMR spectrum of this latter fraction was dominated by the signals of gallic acid and its derivatives, whereas HR MS and HR MS/MS analyses highlighted the diversity in malic acid derivatives. Gallotannins and galloyl flavonol glycosides with…

Single Event Transients and Pulse Quenching Effects in Bandgap Reference Topologies for Space Applications

2016

An architectural performance comparison of bandgap voltage reference variants, designed in a $0.18~\mu \text {m}$ CMOS process, is performed with respect to single event transients. These are commonly induced in microelectronics in the space radiation environment. Heavy ion tests (Silicon, Krypton, Xenon) are used to explore the analog single-event transients and have revealed pulse quenching mechanisms in analogue circuits. The different topologies are compared, in terms of cross-section, pulse duration and pulse amplitude. The measured results, and the explanations behind the findings, reveal important guidelines for designing analog integrated circuits, which are intended for space appli…

Analytical models for the pulse shape of a superconductor-ferromagnet tunnel junction thermoelectric microcalorimeter

2022

AbstractThe superconductor-ferromagnet thermoelectric detector (SFTED) is a novel ultrasensitive radiation detector based on the giant thermoelectric effect in superconductor-ferromagnet tunnel junctions. We demonstrate analytical models and solutions in the time domain for a SFTED operated as a microcalorimeter (pulse excitation), in the linear small-signal limit. Based on these solutions, the signal current and temperature pulse response were studied for two different electrical circuit models, providing design conditions for stable and non-oscillatory response.Kindly check and confirm whether the corresponding author is correctly identified.The corresponding author is correct.
