Se Presenta un estudio retrospectivo en 31 pacientes sometidos a reoperaciones coronarias por tercera o cuarta vez, en un periodo de 15 años en Toledo, Ohio. La indicación más frecuente fue la angina recurrente clase III o IV de la Clasificación de NuevaYork. El método más usado para las reintervenciones fue la cardioplegia mixta con apertura esternal desde el Xifoides, La sobrevivencia a los 12 años fue de 74%. Se incluye que la edad joven, como revascularización previa incompleta, la enfermedad de 162 arterias y la obstrucción de Puentes a la descendente anterior, son indicadores de reoperación. Los Puentes venosos son más Propensos a embolizar periféricamente y se sugiere el uso de Puentes artificiales de la Mamaria Interna para aminorar las complicaciones.

Over the past few years, we have witnessed the widespread deployment of wireless sensor networks and distributed data management facilities: two main building blocks of the Internet of things (IoT) technology. Due to the spectacular increase on the demand for novel information services, the IoT-based infrastructures are more and more characterized by their geographical sparsity and increasing demands giving rise to the need of moving from a cloud to a fog model: a novel deployment paradigm characterized by the provisioning of elastic resources geographically located as close as possible to the end user. Despite the large number of wireless sensor networks already available in the market, there are still many issues to be addressed on the design and deployment of robust network platforms capable of meeting the demand and quality of fog-based systems. In this paper, we undertake the design...

This paper presents a comprehensive update of the structural damage assessment of the complex Huaca de la Luna, which is one the most important heritage monuments in northern Peru, and was built by the Moche civilization from 100 AD to 650 AD. The paper presents an overview of the initial hypothesis identified to explain the nature of the damage encountered in the Huaca. The results highlight how the combination of material evaluations, coupled with geotechnical investigations have been essential in constructing a series of 2D nonlinear FE models for the structural analyses under gravitational loading of the Huaca. Results of the analyses conducted to date show the importance of a multidisciplinary approach for assessing the structural safety in these types of buildings. © 2016 Taylor & Francis Group, London.
