The Poggio-Miller-Chang-Harrington-Wu-Tsai (PMCHWT) equation is one of the most widespread full-wave integral formulations for modeling the electromagnetic scattering from penetrable obstacles. Unfortunately, it suffers from sources of ill-conditionin

Simulation-based education is an essential tool in modern health care, enhancing technical, behavioral, and decision-making skills while improving patient safety and clinical outcomes. In Italy, health care simulation has developed over the past 2 decades, with multiple scientific societies and educational initiatives promoting its use. However, the absence of national data and standardized educational frameworks presents a barrier to its widespread adoption. Recognizing these challenges, the Italian Ministry of Health convened a panel of experts to establish a strategic framework for simulation in health care, aiming to standardize methodologies, promote quality assurance, and foster collaboration across institutions. The panel, composed of experts in health care simulation, clinical practice, and risk management, conducted a series of telematic meetings from April 2022 to July 2022. A consensus-driven approach was adopted to review existing literature, identify key areas for development, and formulate practical recommendations. Key recommendations include: establishing a national registry of simulation programs, defining accreditation criteria for simulation-based education, standardizing professional competencies for simulation educators, integrating simulation into health care curricula and continuous professional development, developing national standards for simulation-based training in new technologies and clinical procedures, utilizing simulation in public health preparedness and emergency response planning, promoting research funding and inter-institutional collaborations. This position paper provides a strategic roadmap for standardizing simulation-based education across the Italian health care system. By establishing national standards and fostering collaboration, simulation can significantly improve patient safety, care quality, and health care system resilience.

En este reporte se presentan actividades lúdicas que permitieron a los estudiantes de Educación Media Básica aprender a operar con números enteros. Se presenta una breve síntesis de su aplicación en estos últimos cinco años, y evidencias de su impacto positivo en el aprendizaje. La temática de los juegos está inspirada en el videojuego Plantas vs Zombies. Un primer juego se fundamenta en el modelo de bloques y se conforma con fichas que tienen dibujadas una planta o un Zombie. Para realizar adiciones de números enteros se enfrentan las fichas anulándose cada planta con un Zombie, como opuestos. Los estudiantes traducen el significado a números enteros planteando una adición y obteniendo la suma luego de combatir. El segundo juego es de cartas, con hechizos que poseen nombres sugerentes (convertidor, multiplicador y anulador) que dan una pista de su efecto. Se concluye que la inclusión de estas actividades manipulativas posibilitó a los estudiantes, por medio de un desprendimiento paulatino, sumar en primera instancia números enteros, deducir cómo realizar la suma e inferir reglas para multiplicar números enteros.

In this paper, we extend some recent works about the Doppler effect in surface waves on water. We improve the experimental set up by exploring several situations: source in motion with constant velocity and receiver at rest, source at rest and receiver in motion with constant velocity, as well as both source and receiver in motion. Thereby we produce fractional frequency changes of the order of 40%–50%, far larger than those obtained by more traditional sound experiments. The experimental setup, the data collection and the data analysis also allow to highlight some aspects relevant from a didactic point of view, in particular, the experimental results clearly show the nonlinearity of the Doppler shift with the moving source velocity.

In this paper we present experimentally and discuss quantitatively two experiments, in which we show how to suppress in turn selectively one of the two normal modes of a system made of two oscillators (each consisting of a cart and a spring), mutually coupled by an interaction spring. This way, while friction is usually considered an undesirable side effect, the role of dissipation is highlighted. We also discuss, from a didactic perspective, how the experiments presented can be useful to introduce fundamental physical concepts and processes.

Molecular typing of pathogenic relevant strains of Legionella pneumophila serogroup 1 is indispensable in determining the epidemiology of the disease. In addition to classical serotyping and subtyping using monoclonal antibodies, a variety of molecular methods have been successfully employed for epidemiological purposes including amplified fragment length polymorphism (AFLP) analysis, pulsed-field gel electrophoresis, random amplified polymorphic DNA, and many other PCR-based methods. These techniques are currently used because of their feasibility, rapidity, and great potential for discrimination. Multilocus sequence typing (MLST) is a sequence-based variation of multilocus enzyme electrophoresis (MLEE), where several genes are compared simultaneously at their sequence level. In the future, the authors plan to validate MLST method for the whole panel of strains, and also to test other target genes, to evaluate the usefulness of MLST for L. pneumophila serogroup 1. MLST appears to be a promising typing technology, and by the selection of novel target genes this method has the potential of becoming the gold standard for L. pneumophila population studies.
