La trazabilidad y el correcto etiquetado de los piensos y sus ingredientes son factores esenciales para prevenir fraudes y garantizar la seguridad alimentaria. En el ámbito de la lucha contra las Encefalopatías Espongiformes Transmisibles (EETs), la prohibición de la Unión Europea (UE) de alimentar a rumiantes y otros animales de granja con harinas de carne y huesos derivadas de animales, hace necesaria la disponibilidad de metodologías que permitan identificar el origen de las materias primas e ingredientes presentes en los piensos. El método oficial de análisis microscópico tradicionalmente empleado para este fin presenta limitaciones a la hora de diferenciar entre los huesos de mamíferos y de aves, así como para determinar el origen animal específico de las partículas detectadas. Por ello, una de las prioridades de la UE en los últimos años ha sido potenciar la búsqueda y desarrollo de técnicas analíticas alternativas que permitan la detección específica de todos los componentes que integran los piensos. Teniendo en cuenta estos aspectos, en esta Tesis Doctoral se han desarrollado técnicas de PCR en tiempo real con sondas TaqMan® para el control de autenticidad y trazabilidad de ingredientes de origen animal utilizados en la fabricación de los piensos. Las especies objeto de este trabajo han sido: vaca (Bos taurus), oveja (Ovis aries), cabra (Capra hircos), grupo rumiante, cerdo (Sus scrofa), pollo (Gallus gallos), pavo (Meleagris g-allopavo), pato (Anal platyrhynchos x Cairina moschata), oca (Anser anser), grupo aviar, caballo (Equus caballus), conejo (Oryctolagus cuniculus), liebre (Lepus capensis), grupo lepórido (conejo y liebre) y pescados...

This dissertation aims to explore the contemporary Caribbean and its dramaturgy through the study of the artistic work of two remarkable artists: the Puerto Rican Teresa Hernández and the Dominicanyork Josefina Báez. Both artists are currently generating a lot of attention due to the internationalization of their creations, but still their work deserves even more consideration. These skilled stage artists connect various islands through their artistic work: Puerto Rico, the Dominican Republic, and the islands within New York City. The different cultures that converge and coexist in these places exemplify the process of hybridization that characterizes our modern world. Teresa and Josefina illustrate in their plays the plurality of the Caribbean, depicting a true multiplicity of languages and cultures that makes it impossible to adopt a fixed and unique conception of a national identity. They engage in the difficult task of finding out what it means to be a Puerto Rican, a Dominican or a New Yorker. Both performers clearly criticize the notion of an identity that pretends to fuse and include all the possible voices of every Caribbean nation under a sole definition. Therefore, one must consider the heterogeneity that surrounds us as the basis to approach the work of these two artists when evaluating the Caribbean, as well as the dramaturgical procedures these great performers employ. To begin with, how can we talk about the Caribbean? How can we talk accurately about dramaturgical procedures? Furthermore, how can we express with words the ephemeral aspect of the theatrical event? How can we use words to address a Caribbean reality, which contains European and American standards, but does not necessarily follow them? These are the questions that the present investigation seeks to answer; however, it is not an easy task. Thus, the real challenge of this dissertation is to offer a rigorous response to these questions...
