Preventing Violence in Seven Countries: Global Convergence in Policies
2007
Do governments take the measures that are supported by the best scientific evidence available? We present a brief review of the situation in: Australia, Canada, Germany, the Netherlands, Spain, the United Kingdom, and the United States. Our findings show surprisingly similar developments across countries. While all seven countries are moving towards evidence-based decision making regarding policies and programs to prevent violence, there remain a number of difficulties before this end can be achieved. For example, there continue to be few randomized controlled trials or rigorous quasi-experimental studies on aggression and violence. Results from experimental research are essential to both p…

The use of camera and LiDAR sensors to sense the environment has gained increasing popularity in robotics. Individual sensors, such as cameras and LiDARs, fail to meet the growing challenges in complex autonomous systems. One such scenario is autonomous mooring, where the ship has to …
Probabilistic models for the fatigue resistance of welded steel joints subjected to constant amplitude loading
2022
Abstract S-N curves found in various rules and regulations are the basic tool for the practicing engineer when carrying out life predictions for welded details in dynamically loaded structures. The present work is investigating the expected fatigue life and associated scatter for welded steel joints subjected to Constant Amplitude (CA) loading. The objective is to obtain more reliable life predictions based on advancements in the probabilistic model fitted to collected life data. A Random Fatigue Limit Model (RFLM) is proposed to obtain fatigue resistance curves at given probability levels of survival. As a distinction to more conventional statistical methods, the model is treating both the…
A model study for the progressive disruption of CA1 firing properties during Alzheimer’s disease
2011
Several independent studies show that β-Amyloid (Aβ) peptides accumulation, one of the characteristic hallmark of Alzheimer’s Disease (AD), can affect the normal neuronal activity in different ways causing an increase or a decrease in neuronal membrane excitability. For example, experimental evidence for a negative impact on neuronal membrane in animal models of AD has been obtained in dual patch recordings in rat hippocampal tissue slices, in which Aβ blocked K channels in pyramidal cell dendrites, causing an increase in dendritic membrane excitability. The resulting increased Ca2+ influx and excitoxicity may lead to dendritic degeneration. However, further experimental evidence suggests t…
Medicamentos utilizados en pediatría extrahospitalaria: ¿disponemos de información suficiente?
2008
Objetivo: Analizar los medicamentos que reciben los pacientes pediátricos en el ámbito extrahospitalario y la información disponible sobre los mismos. Pacientes y métodos: Estudio transversal, observacional y descriptivo realizado en una muestra de pacientes menores de 14 años atendidos en urgencias del Servicio de Pediatría del Consorcio Hospital General Universitario de Valencia entre junio 2005 y agosto 2006. Se cuantifican y clasifican los medicamentos utilizados antes de acudir a urgencias y se analiza la información sobre su uso que contiene el Vademécum Internacional Medicom y la ficha técnica. Resultados: Se recogió información sobre 462 niños con media de edad de 5,2 años (interval…

WITHDRAWN: Diagnóstico de la tuberculosis en la edad pediátrica
2010
La tuberculosis continua siendo uno de los problemas sanitarios mas importantes en el mundo. En paises desarrollados se esta asistiendo a un aumento de casos, incluidos los ninos, por diferentes motivos. El mas determinante parece ser la inmigracion procedente de zonas con elevada endemia de tuberculosis. Es prioritario que se establezcan las medidas necesarias para optimizar el diagnostico precoz y adecuado de las distintas formas clinicas de tuberculosis en ninos. Para ello, la Sociedad Espanola de Infectologia Pediatrica y la Sociedad Espanola de Neumologia Pediatrica ambas pertenecientes a la Asociacion Espanola de Pediatria, han decidido realizar el presente documento de consenso, con …
