Influencia de la alimentación sobre los rendimientos productivos en el cebo de conejos

La formulación de un pienso de conejos en crecimiento persigue maximizar los rendimientos productivos (índice de conversión, velocidad de crecimiento y rendimiento a la canal) y limitar la incidencia de trastornos digestivos. Las necesidades de los principales ?principios inmediatos/nutrientes? están bien establecidas (Tabla 1) para el periodo global de cebo, y permiten optimizar los rendimientos productivos en granjas libres de enteropatía epizoótica o que utilicen antibióticos. Sin embargo, la gran incidencia de esta enfermedad durante las dos semanas posteriores al destete ha obligado a profundizar en la fisiología digestiva de los gazapos durante este periodo para tratar de establecer recomendaciones nutricionales que se ajusten mejor sus necesidades, al igual que sucede con lechones y pollos de primera edad.

Evolución temporal de las características de la escara isquémica en un modelo experimental de infarto agudo de miocardio: estudio basado en resonancia magnética

En los pacientes con infarto de miocardio, las características de la escara isquémica, incluyendo la extensión de tejido heterogéneo (TH) y los canales intraescara, se relacionan con la mortalidad arrítmica. Sin embargo, aún no se conoce bien la evolución temporal de la estructura de la escara en los primeros meses tras el infarto agudo de miocardio (IAM).

Supporting patient screening to identify suitable clinical trials.

To support the efficient execution of post-genomic multi-centric clinical trials in breast cancer we propose a solution that streamlines the assessment of the eligibility of patients for available trials. The assessment of the eligibility of a patient for a trial requires evaluating whether each eligibility criterion is satisfied and is often a time consuming and manual task. The main focus in the literature has been on proposing different methods for modelling and formalizing the eligibility criteria. However the current adoption of these approaches in clinical care is limited. Less effort has been dedicated to the automatic matching of criteria to the patient data managed in clinical care. We address both aspects and propose a scalable, efficient and pragmatic patient screening solution enabling automatic evaluation of eligibility of patients for a relevant set of trials. This covers the flexible formalization of criteria and of other relevant trial metadata and the efficient management of these representations.

dOTM: a mechanism for distributing centralized multi-party video conferencing in the cloud

One of the key factors for a given application to take advantage of cloud computing is the ability to scale in an efficient, fast and reliable way. In centralized multi-party video conferencing, dynamically scaling a running conversation is a complex problem. In this paper we propose a methodology to divide the Multipoint Control Unit (the video conferencing server) into more simple units, broadcasters. Each broadcaster receives the media from a participant, processes it and forwards it to the rest. These broadcasters can be distributed among a group of CPUs. By using this methodology, video conferencing systems can scale in a more granular way, improving the deployment.

Dynamic media stream mobility with TURN

Multi party videoconference systems use MCU (Multipoint Control Unit) devices to forward media streams. In this paper we describe a mechanism that allows the mobility of such streams between MCU devices. This mobility is especially useful when redistribution of streams is needed due to scalability requirements. These requirements are mandatory in Cloud scenarios to adapt the number of MCUs and their capabilities to variations in the user demand. Our mechanism is based on TURN (Traversal Using Relay around NAT) standard and adapts MICE (Mobility with ICE) specification to the requirements of this kind of scenarios. We conclude that this mechanism achieves the stream mobility in a transparent way for client nodes and without interruptions for the users.
