[SPA] El aumento de la población mundial y el sistema actual de consumo requiere un nuevo sistema de entendimiento de la economía, consistente en rediseñar, producir, consumir, reutilizar y reciclar. Dentro del sistema de economía circular entra en juego el etiquetado de alimentos, que aporta al consumidor una información no solo en el momento de compra sino en futuras decisiones. La actual información presente en los alimentos está regulada en Europa por el Reglamento 1169/2011 del Parlamento Europeo, pero esta información no es suficiente para conocer aspectos de la salud, el respeto por el medio ambiente, la calidad del producto, proceso, uso, re-uso y/ destino del envase y otros, información requerida para el proceso de cambio de la economía circular. En este aspecto puede entrar en juego la innovación de esta información. Para garantizar que el consumidor acceda a esta información se requiere que esta innovación esté soportada por el uso de las nuevas tecnologías, con la aplicación de nuevas etiquetas. [ENG] The increase in world population and the current system of consumption requires a new system of understanding of the economy, which consists of redesigning, producing, consuming, reusing and recycling. Food labelling comes into play within the circular economy system, which provides the consumer with information not only at the time of purchase, but also in future decisions. The current information on food is regulated in Europe by Regulation 1169/2011 of the European Parliament, but this information is not enough to know aspects such as health, environment respect, the quality of the product, the process, the use, the reuse and the journey of the food container and others. Information required for the process of changing the circular economy. In this aspect, the innovation of this information can come into play. To ensure that the consumer accesses this information, it is required that this innovation be demanded by the use of new technologies, with the application of new labels. ; El doctorando desea ...

22 pags., 27 figs., 6 tabs. ; Context. Yebes 40 m radio telescope is the main and largest observing instrument at Yebes Observatory and is devoted to very long baseline interferometry (VLBI) and single-dish observations since 2010. It has been covering frequency bands between 2 GHz and 90 GHz in discontinuous and narrow windows in most cases in order to match the current needs of the European VLBI Network (EVN) and the Global Millimeter VLBI Array (GMVA). Aims. The Nanocosmos project, a European Union-funded synergy grant, has enabled an increase in the instantaneous frequency coverage of the Yebes 40 m radio telescope, making it possible to observe many molecular transitions with single tunings in single-dish mode. This reduces the observing time and maximises the output from the telescope. Methods. We present technical specifications of the recently installed 31.5-50 GHz (Q band) and 72-90.5 GHz (W band) receivers along with the main characteristics of the telescope at these frequency ranges. We observed IRC+10216, CRL 2688, and CRL 618, which harbour a rich molecular chemistry, to demonstrate the capabilities of the new instrumentation for spectral observations in single-dish mode. Results. Our results show the high sensitivity of the telescope in the Q band. The spectrum of IRC+10126 offers an unprecedented signal-to-noise ratio for this source in this band. On the other hand, the spectrum normalised by the continuum flux towards CRL 618 in the W band demonstrates that the 40 m radio telescope produces comparable results to those from the IRAM 30 m radio telescope, although with a lower sensitivity. The new receivers fulfil one of the main goals of Nanocosmos and open up the possibility to study the spectrum of different astrophysical media with unprecedented sensitivity. ; The research leading to these results has received funding from the European Research Council under the European Union's Seventh Framework Programme (FP/2007-2013)/ERC-SyG-2013 Grant Agreement No. 610256 Nanocosmos. Part of this work was supported by Programa operativo pluriregional de España, YDALGO. The observations mentioned in this article have been done under commissioning time and within projects 19A010 and 20A017. The Yebes 40m radio telescope belongs to Instituto Geográfico Nacional (IGN).
