Compilation of downward flux observations from sediment trap deployments in the Atlantic Ocean - Contribution to EURO-BASIN's Data integration

We provide a compilation of downward fluxes (total mass, POC, PON, BSiO2, CaCO3, PIC and lithogenic/terrigenous fluxes) from over 6000 sediment trap measurements distributed in the Atlantic Ocean, from 30 degree North to 49 degree South, and covering the period 1982-2011. Data from the Mediterranean Sea are also included. Data were compiled from different sources: data repositories (BCO-DMO, PANGAEA), time series sites (BATS, CARIACO), published scientific papers and/or personal communications from PI's. All sources are specifed in the data set. Data from the World Ocean Atlas 2009 were extracted to provide each flux observation with contextual environmental data, such as temperature, salinity, oxygen (concentration, AOU and percentage saturation), nitrate, phosphate and silicate.

To Madagascar and back: long-distance, return migration across open ocean by a pregnant female bull shark Carcharhinus leucas

A large, pregnant, female bull shark Carcharhinus leucas was tracked migrating from Seychelles across open ocean to south-east Madagascar, c. 2000 km away, and back again. In Madagascar, the shark spent a prolonged period shallower than 5 m, consistent with entering estuarine habitat to pup, and upon return to Seychelles the shark was slender and no longer gravid. This represents an unprecedented return migration across the open ocean for a C. leucas and highlights the need for international collaboration to manage the regional C. leucas population sustainably.

Red Bull, un ejemplo paradigmático de las nuevas estrategias de comunicación de las marcas en el entorno digital

Introducción: En la presente investigación nos vamos a centrar en los contenidos on line que ofrece la marca Red Bull ya sea a través de su web www.redbull.tv o de su App Red Bull TV. Red Bull como marca necesita destacar de entre todo el ruido publicitario, necesita hacerse notar y llegar hasta sus consumidores, pero hoy en día las audiencias están fragmentadas, las audiencias no están sometidas al dictado programático de las televisiones. Cada vez más, y sobre todo en el público joven, que es aquel con el que más se identifica esta marca, es un público activo que genera sus propias parrillas de programación, que busca aquello que realmente quiere ver. Entonces, ¿cómo una marca logra que se le escuche? a través del Rock&Love: sorprender y dar amor. Hipótesis: Nuestra hipótesis de partida es que Red Bull, en la búsqueda de conexión con su público, les ofrece contenidos de su interés que les reafirma en su acercamiento a la marca, y así lograr el Rock&Love. Objetivos: De acuerdo con la hipótesis, son tres los objetivos que van a guiar la presente investigación: el primero, conocer las claves de Red Bull en el entorno digital. El segundo, realizar un análisis de los contenidos utilizados por la marca para aproximarse a sus usuarios teniendo en cuenta los nuevos hábitos de consumo. El tercero, analizar la diferencia de contenidos según el medio en que se difunde. Metodología: Para corroborar o no nuestra hipótesis participaremos del método cualitativo y del método cuantitativo. Las técnicas a utilizar son la observación documental y el análisis de contenido. Conclusiones: Este análisis de contenido Ad Hoc ha permitido la obtención de datos cuantitativos y nos ha facilitado la aproximación a nuestros objetivos de forma cualitativa y de esta forma, se ha logrado dar respuesta a la hipótesis de partida y confirmar que la marca recurre al Rock&Love en los contenidos que muestran a través de las diferentes plataformas de Red Bull TV.

Bull's eye leaky wave antenna for terrestrial and space applications

This work presents the study of Bull's eye antenna designs, a type of leaky wave antenna (LWA), operating in the 60 GHz band. This band emerged as a new standard for specific terrestrial and space applications because the radio spectrumbecomes more congested up to the millimetre-wave band, starting at 30 GHz. Built on existing Bull's eye antenna designs, novel structures were simulated, fabricated and measured, so as to provide more exibility in the implementation of wireless solutions at this frequency. Firstly, the study of a 60 GHz Bull's eye antenna for straightforward integration onto a CubeSat is presented. An investigation of the design is carried out, from the description of the radiation mechanism supported by simulation results, to the radiation pattern measurement of a prototype which provides a gain of 19.1 dBi at boresight. Another design, based on a modified feed structure, uses a microstrip to waveguide transition to provide easier and inexpensive integration of a Bull's eye antenna onto a planar circuit. Secondly, the design of Bull's eye antennas capable of creating beam deflection and multi-beam is presented. In particular, a detail study of the deflection mechanism is proposed, followed by the demonstration of a Bull's eye antenna generating two separate beams at ±16° away from the boresight. In addition, a novel mechanically steerable Bull's eye antenna, based on the division of the corrugated area in paired sectors is presented. A prototype was fabricated and measured. It generated double beams at ±8° and ±15° from the boresight, and a single boresight beam. Thirdly, a Bull's eye antenna capable of generating two simultaneous orbital angular momentum (OAM) modes l = 3 is proposed. The design is based on a circular travelling wave resonator and would allow channel capacity increase through OAM multiplexing. An improved design based on two stacked OAM Bull's eye antennas capable of producing four orthogonal OAM modes l = (±3,±13) simultaneously is presented. A novel receiving scheme based on discretely sampled partial aperture receivers (DSPAR) is then introduced. This solution could provide a lower windage and a lower cost of implementation than current whole or partial continuous aperture.

Chatter avoidance in the milling of thin floors with bull-nose end mills: Model and stability diagrams

The milling of thin parts is a high added value operation where the machinist has to face the chatter problem. The study of the stability of these operations is a complex task due to the changing modal parameters as the part loses mass during the machining and the complex shape of the tools that are used. The present work proposes a methodology for chatter avoidance in the milling of flexible thin floors with a bull-nose end mill. First, a stability model for the milling of compliant systems in the tool axis direction with bull-nose end mills is presented. The contribution is the averaging method used to be able to use a linear model to predict the stability of the operation. Then, the procedure for the calculation of stability diagrams for the milling of thin floors is presented. The method is based on the estimation of the modal parameters of the part and the corresponding stability lobes during the machining. As in thin floor milling the depth of cut is already defined by the floor thickness previous to milling, the use of stability diagrams that relate the tool position along the tool-path with the spindle speed is proposed. Hence, the sequence of spindle speeds that the tool must have during the milling can be selected. Finally, this methodology has been validated by means of experimental tests.
