Complete minimal surfaces in R3 with a prescribed coordinate function

In this paper we construct complete simply connected minimal surfaces with a prescribed coordinate function. Moreover, we prove that these surfaces are dense in the space of all minimal surfaces with this coordinate function (with the topol- ogy of the smooth convergence on compact sets).Ministerio de Educación y Ciencia MTM2007-61775Ministerio de Educación y Ciencia MTM2007-6450

Harmonic mappings and conformal minimal immersions of Riemann surfaces into RN

We prove that for any open Riemann surface N, natural number N ≥ 3, non-constant harmonic map h:N→R N−2 and holomorphic 2-form H on N , there exists a weakly complete harmonic map X=(Xj)j=1,…,\scN:N→R\scN with Hopf differential H and (Xj)j=3,…,\scN=h. In particular, there exists a complete conformal minimal immersion Y=(Yj)j=1,…,\scN:N→R\scN such that (Yj)j=3,…,\scN=h . As some consequences of these results (1) there exist complete full non-decomposable minimal surfaces with arbitrary conformal structure and whose generalized Gauss map is non-degenerate and fails to intersect N hyperplanes of CP\scN−1 in general position. (2) There exist complete non-proper embedded minimal surfaces in R\scN, ∀\scN>3.Ministerio de Ciencia y Tecnología MTM2007-61775Ministerio de Ciencia y Tecnología MTM2007-64504Junta de Andalucía P09-FQM-508

Complete minimal surfaces and harmonic functions

We prove that for any open Riemann surface N and any non constant harmonic function h : N → R, there exists a complete conformal minimal immersion X : N → R3 whose third coordinate function coincides with h. As a consequence, completeminimal surfaceswith arbitrary conformal structure andwhose Gauss map misses two points are constructed.Ministerio de Educación y Ciencia MTM2007-61775Ministerio de Educación y Ciencia MTM2007-64504Junta de Andalucía P06-FQM-01642

Dynamic impedances of bridge abutments

The soil-structure interaction at bridge abutments may introduce important changes in the dynamic properties of short to medium span bridges. The paper presents the results obtained, through the use of the Boundary Element Method (B.E.M.) technique in several typical situations, including semiinfinite and layered media. Both stiffness and damping properties are included

How Does the Financial Crisis Affect Developing Countries?

The global economy is in crisis as a result of inadequate regulation and supervision of banks and financial markets. The prudential regulation and supervision recommended to developing countries was largely ignored in the developed nations. No country, however, is spared from the consequences of the downturn. The impact on developing countries is even greater. (...)How Does the Financial Crisis Affect Developing Countries?

Distribución de "Festuca patula" Desf. en la Península Ibérica; ecología y tamaños poblacionales de sus poblaciones en Las Villuercas y Los Montes de Toledo (CW de España)

Population sizes and habitat types of Festuca patula Desf. are reported for Las Villuercas and Los Montes de Toledo regions (CW Spain). The distribution range of Festuca patula in the Iberian Peninsula is increased with 21 new records: one for Sierra Nevada (Granada, S Spain) and 20 for The Villuercas and Los Montes de Toledo (Cáceres, Toledo and Ciudad Real). The individuals of the latter areas grow under different environmental conditions. They live on rocky or relatively well-developed soils derived from metamorphic rocks, ranging from 300 to 900 m above sea level. They usually grow in temperate caducifolious and marcescent forests but also colonize open scrubs on rocky slopes, often bordering riparian stands. Most of the populations contain less than 100 individuals; only one population has more than 1,000. The population sizes are apparently larger on shady wooded sites with relatively well-developed soils than in rocky sites.Se presentan datos sobre el tamaño de las poblaciones y las preferencias de hábitat de Festuca patula Desf. en Las Villuercas y Los Montes de Toledo (CW de España). Se amplia la información corológica para la península con 21 localidades nuevas: una en Sierra Nevada (Granada) y el resto en Las Villuercas y Los Montes de Toledo (Cáceres, Toledo y Ciudad Real). Las poblaciones de estos dos últimos territorios habitan en distintas condiciones ambientales. Se encuentran entre los 300 y 1.000 m de altitud, instaladas en sustratos metamórficos, creciendo en el sotobosque de frondosas (quejigos, alcornoques, encinas, castaños, etc.) y en los claros de matorrales en laderas rocosas que, en numerosas ocasiones, limitan con formaciones riparias (caracterizadas por alisos, fresnos, sauces, etc.). La mayoría de las poblaciones están integradas por menos de 100 ejemplares y solamente dos alcanzan o superan los 1.000 individuos. El tamaño poblacional parece ser mayor en enclaves con suelo relativamente desarrollado, en ambientes forestales sombríos

Media Representation of the European Union: Comparing Newspaper Coverage in France, Spain, and the United Kingdom

Based on content analysis of newspapers and in-depth interviews of journalists, this article analyzes the role of the media in defining the European Union and, therefore, in contributing to the production and reproduction of social representations of the EU in the public. The research concentrated on three EU member countries: France, Spain, and the United Kingdom. The study is theoretically informed by news production theory. Results demonstrate that there are major differences among the newspapers analyzed here in terms of how they represented the EU in the news, according to their nationality and political orientation. Furthermore, many of the principles that dominate the production of news undermine information on the EU. The material on the EU tends to reinforce traditional views on economics, politics, and society, including the widespread belief that a national government is better than the EU for solving society\u27s problems

National Identity, Nationalism, and the Organization of the European Union

Based on in-depth interviews and document analysis, this article examines the relationships between cultural identification and the process of European integration. It shows that French and Spanish people\u27s cultural attachments to Europe as a common social organization is still very limited and reflects a concern for the defense of a national identity. This research contributes to our understanding of the European integration and to the theory of cultural identity by suggesting a dynamic paradigm that articulates the constitution of a formal organization with the process of cultural identity formation

Impacto de la ley de reestructuración económica en el sector real de la economía en la ciudad de Cartagena entre el 1 de enero del 2000 y diciembre del 2006

La crisis que originó la apertura económica en Colombia generó traumatismos en lo empresarial y lo económico; con situaciones tales como la inadecuada estructura operativa y de costos, la falta de información contable y oportuna en las empresas, el endeudamiento y las tasas de interés y los ajustes integrales por inflación. Por circunstancias como las expuestas anteriormente, es que los procesos concursales en Colombia, se implementan como una herramienta legal diseñada para la consecución de acuerdos o planes de pagos que permitan o procuren la satisfacción de los créditos insolutos a cargo de una persona natural o jurídica que tenga la calidad de comerciante insolvente, en armonía a las normas comerciales, civiles y tributarias aplicables, sin desprenderse de principios básicos de equidad, de igualdad ante la ley y de preservación del derecho a desarrollar una actividad empresarial. Por ello a través del estudio paradigmático de la acción comunicativa, se verifica la eficacia de dicha. normativa concursal
