Analysis of the surface state of epi-ready Ge wafers

The surface state of Ge epi-ready wafers (such as those used on III-V multijunction solar cells) supplied by two different vendors has been studied using X-ray photoemission spectroscopy. Our experimental results show that the oxide layer on the wafer surface is formed by GeO and GeO2. This oxide layer thickness differs among wafers coming from different suppliers. Besides, several contaminants appear on the wafer surfaces, carbon and probably chlorine being common to every wafer, irrespective of its origin. Wafers from one of the vendors show the presence of carbonates at their surfaces. On such wafers, traces of potassium seem to be present too.

Estudio De La Imagen De Marca De Las Entidades Financieras

Esta investigación realiza un estudio de la imagen de marca de distintas entidades financieras que operan en España. Para llevar a cabo esta investigación se utiliza una técnica de marketing denominada Evaluación Periódica de la Imagen (EPI), que proporciona una combinación de las ventajas de las técnicas cuantitativas y cualitativas. Los resultados obtenidos muestran que las dos entidades financieras percibidas más iguales entre sí son La Caixa y Caja Madrid; por el contrario, las dos entidades percibidas más diferentes son el Santander y Caja Madrid. Finalmente, el estudio muestra la imagen relativa, imagen individual y un mapa de posicionamiento de las entidades analizadas.

The morphofunctional approach to emotion modelling in robotics

In this conceptual paper, we discuss two areas of research in robotics, robotic models of emotion and morphofunctional machines, and we explore the scope for potential cross-fertilization between them. We shift the focus in robot models of emotion from information-theoretic aspects of appraisal to the interactive significance of bodily dispositions. Typical emotional phenomena such as arousal and action readiness can be interpreted as morphofunctional processes, and their functionality may be replicated in robotic systems with morphologies that can be modulated for real-time adaptation. We investigate the control requirements for such systems, and present a possible bio-inspired architecture, based on the division of control between neural and endocrine systems in humans and animals. We suggest that emotional epi- sodes can be understood as emergent from the coordination of action control and action-readiness, respectively. This stress on morphology complements existing research on the information-theoretic aspects of emotion.

Información personal: la nueva moneda de la economía digital

Technological progress has profoundly changed the way personal data are collected, accessed and used. Those data make possible unprecedented customization of advertising which, in turn, is the business model adopted by many of the most successful Internet companies. Yet measuring the value being generated is still a complex task. This paper presents a review of the literature on this subject. It has been found that the economic analysis of personal information has been conducted up to now from a qualitative perspective mainly linked to privacy issues. A better understanding of a quantitative approach to this topic is urgently needed.

Soportes digitales y transformación de las industrias de contenidos

In media and content industries, the main effect of digitization has been a radical transformation of information formats and displays. In fact, these formats and displays are responsible for the shifting perceptions of users-consumers concerning how they relate and interact with information. However, in spite of its considerable relevance, the bidirectional relationship between formats/displays and users has been seldom studied. This brief paper presents an overview of the evolution of displays and devices in some key media and content subsectors-publishing and distribution of books and newspapers- with the main objective of hinting at the next steps in their evolution.

Diseño web con Drupal 7

En este documento se van a desarrollar las técnicas para la creación de páginas web utilizando uno de los sistemas de gestión de contenido, también llamado CMS, por sus siglas en inglés, Content Manager System, más potentes del mercado, y open source, es decir de código abierto, como es el caso de Drupal. Se usará este sistema de gestión en su versión 7, y la actualización 37, o lo que es lo mismo, se usará Drupal 7.37, aunque se actualizará a la versión 38, puesto que esta versión fue publicada a mitad de los desarrollos y la versión 8 todavía está en versión beta y no es suficientemente estable como para crear una página web robusta con esa versión del CMS. Estas explicaciones están basadas en dos páginas web creadas en dicho gestor de contenidos, una de ellas ya en producción, www.lrl.es, que también podrá ser accedida desde www.luqueagentescomerciales.es, página web diseñada para un agente comercial de herramientas. La segunda, todavía no está en producción pero se puede acceder a ella desde el servidor wamp montado en local, 81.37.0.251/epi, que es una mejora de la página www.elpactoinvisible.es, diseñada para una galería de arte de Málaga. A lo largo del documento se verán distintas opciones que se pueden llegar a utilizar gracias a Drupal para obtener el resultado esperado y se darán las explicaciones pertinentes para saber cuál de ellas usar para focalizar distintos aspectos según se decida ir por una vía u otra de desarrollo, y se mostraran, con código cuando sea necesario, las soluciones utilizadas en las distintas páginas, de las que se ha hablado en el párrafo precedente, y el porqué de usar esa solución en vez de otras alternativas que también son viables para dichos objetivos. ABSTRACT This paper will develop techniques for creating web pages using one of the systems content management, also called CMS, for its acronym in English, Content Manager System, and the most powerful in the market, and open source, as is the case of Drupal. This management system in its version 7, and updating 37, or as it is called, Drupal 7.37 is used, although it will be updated to version 38, because this version was published in the middle of the developments and version 8 is still in beta and is not stable enough to create a robust site with this version of CMS. These explanations are based on two websites created in this CMS, one of them already in production, www.lrl.es, which also can be accessed from www.luqueagentescomerciales.es, web page designed for a tools commercial agent. The second one, is not yet in production but can be accessed from the WAMP server installed locally, 81.37.0.251/epi, which is an improvement to www.elpactoinvisible.es page, designed for an art gallery in Malaga. Throughout the document you can get several options to be used thanks to Drupal in order to achieve result and explanations will be given to indicate one of theme to use for targeting different aspects and which developing method or path to follow and will be shown, in code if it should be necessary, the solutions used in different pages which have been discussed in the preceding paragraph, and why to use that solution instead of other alternatives are also viable for such purposes.

Effect of the season on the free phytoprostanes content in Cornicabra extra virgin olive oil from deficit irrigated olive trees

BACKGROUND: The effect of regulated deficit irrigation (RDI) on the phytoprostane (PhytoP) content in extra virgin olive (Olea europaea L., cv. Cornicabra) oil (EVOO) was studied. During the 2012 and 2013 seasons, T0 plants were irrigated at 100% ETc, while T1 and T2 plants were irrigated avoiding water deficit during phases I and III of fruit growth and saving water during the non-critical phenological period of pit hardening (phase II), developing amore severewater deficit in T2 plants. In 2013, a fourth treatment (T3) was also performed, which was similar to T2 except that water saving was from the beginning of phase II to 15 days after the end of phase II. RESULTS: 9-F1t-PhytoP, 9-epi-9-F1t-PhytoP, 9-epi-9-D1t-PhytoP, 9-D1t-PhytoP, 16-B1-PhytoP and 9-L1-PhytoP were present in Cornicabra EVOO, and their contents increased in the EVOO fromRDI plants. CONCLUSION: Deficit irrigation during pit hardening or for a further period of 2 weeks thereafter to increase irrigation water saving is clearly critical for EVOO composition because of the enhancement of free PhytoPs, which have potential beneficial effects on human health. The response of individual free PhytoPs to changes in plant water status was not as perceptible as expected, preventing their use as biomarkers of water stress.
