During the last decade, wind energy has been the fastest growing renewable source of energy worldwide. Limited sources of fossil fuel in addition to the negative effects of greenhouse gas emissions on the environment have led many countries to support development of renewable energies such as wind energy. Spain as the fourth biggest producer of wind energy plays an important global role in wind industry. In this paper, some important factors in the rapid growth of wind energy in Spain such as policy design, industry and technology, economic environment and social acceptance have been studied. The objective of this study is to introduce a model based on the successful development of wind energy in Spain which can be implemented by other countries

In 1933 public letter to Wilhelm Furtwängler, Joseph Goebbels synthesized the official understanding of the link between politics, art and society in the early steps of the Third Reich. By assuming the ethos of art, politics acquired a plastic agency to mold its objects —population and the state— as a unified entity in the form of a ‘national-popular community’ (Volksgemeinschaft); in turn, by infusing art with a political valence, it became part of a wider governmental apparatus that reshaped aesthetic discourses and practices. Similar remarks could be made about the ordering of cities and territories in this period. Dictatorial imaginations mobilized urbanism —including urban theory, urban design and planning— as a fundamental tool for social organization. Under their aegis the production of space became a moment in a wider production of society. Many authors suggest that this political-spatial nexus is intrinsic to modernity itself, beyond dictatorial regimes. In this light, I propose to use dictatorial urbanisms as an analytical opportunity to delve into some concealed features of modern urban design and planning. This chapter explores some of these aspects from a theoretical standpoint, focusing on the development of dictatorial planning mentalities and spatial rationalities and drawing links to other historical episodes in order to inscribe the former in a broader genealogy of urbanism. Needless to say, I don’t suggest that we use dictatorships as mere templates to understand modern productions of space. Instead, these cases provide a crude version of some fundamental drives in the operationalization of urbanism as an instrument of social regulation, showing how far the modern imagination of sociospatial orderings can go. Dictatorial urbanisms constituted a set of experiences where many dreams and aspirations of modern planning went to die. But not, as the conventional account would have it, because the former were the antithesis of the latter, but rather because they worked as the excess of a particular orientation of modern spatial governmentalities — namely, their focus on calculation, social engineering and disciplinary spatialities, and their attempt to subsume a wide range of everyday practices under institutional structuration by means of spatial mediations. In my opinion the interest of dictatorial urbanisms lies in their role as key regulatory episodes in a longer history of our urban present. They stand as a threshold between the advent of planning in the late 19th and early 20th century, and its final consolidation as a crucial state instrument after World War II. We need, therefore, to pay attention to these experiences vis-à-vis the alleged ‘normal’ development of the field in contemporary democratic countries in order to develop a full comprehension thereof.

We have analysed the geochemical (element analysis), mineralogical and sedimentary facies to characterize the sedimentary record in Fuentillejo maar-lake in the central Spanish volcanic field of Campo de Calatrava and thus be able to reconstruct the cyclicity of the sedimentary and paleoclimatic processes involved. The upper 20 m of core FUENT-1 show variations in clastic input and water chemistry in the lake throughout the last 50 ka cal BP. Being a closed system, the water level in this maar-lake depends primarily on the balance between precipitation and evaporation

An online open access test (CREAX self-assessment) has been used in this work so that students from degrees in engineering in the Universidad Polite¿cnica of Madrid (UPM) could self-assess their creative competence after several classroom activities. Different groups from the first year course have been statistically compared using data from their assessment. These first year students had different professors in the subject ?Technical Drawing? and belonged to several degrees in the UPM. They were as well compared regarding sex and a group of first year students was also compared to another last year group of the degree so as to observe possible differences in the achievement of this competence. Only one difference was detected concerning sex in one of the degrees. Among degrees, the higher marks obtained by students who had done specific exercises for the development of creativity in class is highlighted. Finally, a significantly high mark was observed in students during their last year of degree with respect to first year students. The tool CREAX has become very useful in the assessment of this competence in the UPM degrees in which it has been implemented.

We reconstructed vegetation responses to climate oscillations, fire and human activities since the last glacial maximum in inland NW Iberia, where previous paleoecological research is scarce. Extremely sparse and open vegetation composed of steppic grasslands and heathlands with scattered pioneer trees suggests very cold and dry conditions during the Oldest Dryas, unsuitable for tree survival in the surroundings of the study site. Slight woodland expansion during the Bolling/Allerod was interrupted by the Younger Dryas cooling. Pinewoods dominated for most of the early Holocene, when a marked increase in fire activity occurred. Deciduous trees expanded later reaching their maximum representation during the mid-Holocene. Enhanced fire activity and the presence of coprophilous fungi around 6400-6000 cal yr BP suggest an early human occupation around the site. However, extensive deforestation only started at 4500 calyrBP, when fire was used to clear the tree canopy. Final replacement of woodlands with heathlands, grasslands and cereal crops occurred from 2700 cal yr BP onwards due to land-use intensification. Our paleoecological record can help efforts aimed at restoring the natural vegetation by indicating which communities were dominant at the onset of heavy human impact, thus promoting the recovery of currently rare oak and alder stands.

To further develop Integrated Pest Management (IPM) strategies against crop pests, it is important to evaluate the effects of insecticides on biological control agents. Therefore, we tested the toxicity and sublethal effects (fecundity and fertility) of flonicamid, flubendiamide, metaflumizone, spirotetramat, sulfoxaflor and deltamethrin on the natural enemies Chrysoperla carnea and Adalia bipunctata. The side effects of the active ingredients of the insecticides were evaluated with residual contact tests for the larvae and adults of these predators in the laboratory. Flonicamid, flubendiamide, metaflumizone and spirotetramat were innocuous to last instar larvae and adults of C. carnea and A. bipunctata. Sulfoxaflor was slightly toxic to adults of C. carnea and was highly toxic to the L4 larvae of A. bipunctata. For A. bipunctata, sulfoxaflor and deltamethrin were the most damaging compounds with a cumulative larval mortality of 100%. Deltamethrin was also the most toxic compound to larvae and adults of C. carnea. In accordance with the results obtained, the compounds flonicamid, flubendiamide, metaflumizone and spirotetramat might be incorporated into IPM programs in combination with these natural enemies for the control of particular greenhouse pests. Nevertheless, the use of sulfoxaflor and deltamethrin in IPM strategies should be taken into consideration when releasing either of these biological control agents, due to the toxic behavior observed under laboratory conditions. The need for developing sustainable approaches to combine the use of these insecticides and natural enemies within an IPM framework is discussed.

El arquitecto Pedro Muguruza (1893-1952) fue protagonista de la cultura arquitectónica española de la primera mitad del siglo XX. El estudio de su obra ha sido una carencia dentro de la historiografía de la materia, por lo que la tesis constituye una primera investigación en conjunto de su trayectoria profesional. Muguruza realizó una obra abundante y diversa, pero además fue catedrático de la Escuela de Arquitectura de Madrid, académico de San Fernando y primer director general de arquitectura; datos que corroboran la necesidad de haber desarrollado una monografía con un enfoque global. La tesis ha ordenado, clasificado y analizado sus trabajos, tanto desde un punto de vista histórico como desde el punto de vista arquitectónico. En la investigación se ha recurrido a fuentes primarias y secundarias; y una de las aportaciones de la tesis es el riguroso soporte documental sobre el que se asienta. El trabajo tiene un desarrollo cronológico, dividido en tres capítulos identificados como las etapas generales de su carrera: 1. Años de formación y trayectorias iniciales (1909- 1923), 2. Desarrollo profesional (1923-1938), 3. Las tareas en la administración estatal y último periodo (1938-1952). Asimismo, se ha llevado a cabo el catálogo de su obra —también ordenado cronológicamente—, herramienta que posibilita recorrer de principio a fin el listado y las referencias de su arquitectura. En este apartado se han reproducido más de 1.200 imágenes de 294 proyectos. La tesis ha revisado y descubierto la obra de un arquitecto de mayor recorrido y versatilidad del conocido hasta ahora; personaje complejo de abordar, asociado al franquismo, —cuando en realidad desarrolló una gran parte de sus proyectos en la década de los años veinte y treinta—, difícil de abarcar en todas sus dimensiones, arquitectónica, artística e institucional. La investigación ha permitido indagar y exponer sus proyectos iniciales hasta los de la etapa de madurez, gracias a lo que se han determinado los géneros y los procesos de su trabajo, las constantes de su trayectoria y las referencias e influencias que recibió, tanto de corrientes nacionales como de extranjeras. También se ha revisado su pensamiento arquitectónico a través de sus escritos. El trabajo ofrece un panorama más completo del que entonces se tenía del polifacético Muguruza; arquitecto que se puede presentar como un prototipo reflejo de nuestro pasado reciente, y que al conocer su obra se conoce una parte significativa y destacada de la historia de la arquitectura española contemporánea. ABSTRACT Architect Pedro Muguruza (1893-1952) was a pivotal figure in the Spanish architectural culture of the first half of the 20th century. However, his work as a whole has been insufficiently approached by architectural historiography. This thesis is indeed the first comprehensive research of his professional career. Muguruza’s work is abundant and diverse. He was also a professor at the School of Architecture in Madrid, a luminary scholar at the Royal Academy of Fine Arts of San Fernando and the first General Director of Architecture in Spain. All these facts compel a profound monographic exploration of his far-reaching working path. Muguruza’s projects have been organized, classified and analyzed in this thesis both from historical and architectural points of view. Primary and secondary sources have been scrutinized throughout this research and one of the assets of this project is the rigorous documentation on which it is firmly grounded. The results of this research have been chronologically organized and structured into three chapters identified with the general stages of his prolific career: 1. Training years and his initial paths (1909-1923). 2. Professional development (1923-1938). 3. His role in the state administration and his last period (1938-1952). A chronological catalogue of all his architectural work has also been carried out as part of this project. This catalogue offers the possibility to track his works and all references to them under a historical perspective. More than 1,200 images of his projects have been included in this catalogue. The thesis has gone through and shown up the work of an architect whose magnitude and versatility is much more than what previously known. Muguruza represents a complicated figure to approach ideologically speaking because of his later relationship to Franco’s regime – when in fact Muguruza developed a big part of his projects in the 20’s and 30’s before the dictatorship –. He is also a difficult figure to research on because of his exhaustive working activity in different dimensions: architectural, artistic and institutional. This research allows any incoming scholars to approach Muguruza’s projects under an accurate perspective. From his initial works to his maturity period, his projects have been analyzed and classified by establishing different stages. Additionally, some constant guidelines within his long career and the influences he received both in Spain and abroad have also been identified and properly considered. His architectural line of thought has been explored through his writings too. This thesis provides a complete overview of a multifaceted Muguruza, an architect who can be introduced as an archetype of our recent cultural heritage. By exploring his work a quintessential part of the Spanish contemporary architecture is definitively revealed and acknowledged.

He largest proportion of illiteracy and lack of access to education in the world is concentrated in rural areas; therefore it is important to ensure there is access to quality education in these spots. This challenge is assumed by different branches of social research and it is reflected within the publication of articles in scientific journals. In the present document the scientific discourse surrounding the theme of rural education during the last decade was analyzed. To do this, the paper focuses on three aspects: the countries that set the agenda, the geographical areas that represent most of the attention and the prevalent themes within continents. It was observed that USA was the most productive country in terms of scientific writings with 30%; that Asia is really interested in health issues associated to rural education; that in Europe gender issues are on the table and that the African and Asian continents, as well as Latin America, are interested only on their own issues, as 100% of the times they only wrote about themselves.
