Equivalent Circuit for Double Annular Aperture Frequency Selective Surfaces

In this work a double annular aperture frequency selective surface is analyzed from an equivalent circuit perspective. A comparison between full wave numerical solution and the proposed equivalent circuit results is provided for different examples. A very good agreement is obtained endowing the equivalent circuit with great potential as a very powerful and efficient design tool for advanced space filters

Stamps, tourism and gastronomy: The role of gastronomy in promoting tourism in Spain through the postage stamps

El objetivo de este artículo es analizar el papel de los sellos de correos en tanto que instrumentos de promoción turística, a través de la gastronomía como motivo representado. Para ello, analizaremos el caso de las emisiones de estas características en España, desde sus primeras representaciones, a finales de los años ochenta del siglo XX, hasta el momento actual. A través del análisis propuesto, observaremos, por un lado, el uso y la evolución de estas imágenes en su relación, tanto con aquello que representan y con sus usos y valores sociales, como con el interés como atractivo turístico que de ellas se desprende. Por otro lado, observaremos también la íntima relación que existe entre dichas imágenes gastronómicas, algunos de los distintos momentos de la historia reciente del país y su relación con las diferentes políticas institucionales llevadas a cabo.The aim of this article is to analyze the role of postage stamps as instruments for tourism promotion, with gastronomy as a representative motive for travel . To do this, we will analyze the case of the emissions of stamps with these characteristics in Spain, from the first representations,at the end of the eighties of the XX century, through to present times. Through the proposed analysis, we will observe, on the one hand, the use and evolution of these images in their relationship, both with what they represent and with their social uses and values, and their interest as a tourist attraction. We will also observe the intimate relationship between the gastronomic motifs of the stamps and various different moments in the recent history of Spain and their correlation with institutional policies

Proof-of-Concept Application - Annual Report Year 2

This document first gives an introduction to Application Layer Networks and subsequently presents the catallactic resource allocation model and its integration into the middleware architecture of the developed prototype. Furthermore use cases for employed service models in such scenarios are presented as general application scenarios as well as two very detailed cases: Query services and Data Mining services. This work concludes by describing the middleware implementation and evaluation as well as future work in this area. --Grid Computing

Performance Evaluation - Annual Report Year 2

In this paper a performance measuring infrastructure,developed for the prototype and simulator, concering the experiment configuration, data measurement, and data collection, is presented. A corresponding performance evaluation framework is defined to obtain the metrics from the measured data. Initial experiments were carried out to test the developed prototype, simulator and the performance measuring infrastructure. --Grid Computing

Association of increased fibrinogen concentration with impaired activation of anticoagulant protein C

BACKGROUND: Low levels of activated protein C (APC) are a risk factor for venous thrombosis. The mechanisms leading to interindividual differences in APC are not totally elucidated. Protein C is activated by the thrombin-thrombomodulin complex. As thrombin binds to fibrinogen and thrombomodulin through a common region, it is conceivable that fibrinogen influences the activation of protein C. This would help to explain the association between high levels of fibrinogen and an increased thrombotic risk. METHODS: We analyzed the association between circulating APC levels and fibrinogen concentration in 382 healthy subjects. Subsequently, we studied the effect of increasing fibrinogen concentrations on the APC generation on cultured endothelial cells. RESULTS: An independent inverse association between circulating APC levels and fibrinogen was found [betacoefficient, -0.16; 95% confidence interval (95% CI) -0.26, -0.06; P = 0.001]. For each 100 mg dL(-1) increase in fibrinogen, the independent risk of having low APC levels (<0.7 ng mL(-1)) was almost three times higher (OR 2.8; 95% CI 1.1, 7.2; P = 0.04). Accordingly, a notable association between increasing fibrinogen concentrations and the reduction in the thrombin-thrombomodulin dependent activation of protein C on endothelial cells was found (r = -0.57; P = 0.002). CONCLUSIONS: We present evidence of an inverse association between circulating APC and fibrinogen levels. According to this finding together with the results of our in vitro experiments, we propose that the impairment in the generation of APC on endothelial cells constitutes a new prothrombotic mechanism of fibrinogen
