Espacios máximos con recursos mínimos : edificio Central Lechera CLESA, Alejandro de la Sota

La tesis aborda el estudio de la Central lechera CLESA, uno de los edificios industriales de Alejandro de la Sota más significativos de la década de los años cincuenta en España. Las centrales lecheras fueron abordadas por Sota en distintas ocasiones entre 1955 y 1969, siendo CLESA la única de todas ellas que llega a construirse. Se trata de uno de los exponentes más brillantes de la arquitectura moderna industrial española de la posguerra, incluido en "La arquitectura de la industria, REGISTRO DOCOMOMO IBÉRICO”1 entre la veintena de edificios seleccionados de la arquitectura madrileña de este periodo. Plantea una solución singular para alcanzar la diafanidad exigida en la implantación del proceso de producción. La estructura de las naves se realiza con hormigón pretensado, siendo uno de los pioneros en la utilización de esta técnica. La hipótesis de partida considera la realidad del proyecto construido como respuesta desde la arquitectura a un programa industrial resuelto con sencillez, que partiendo de una economía de recursos que le es inherente, consigue desde la coherencia del planteamiento, soluciones donde la complejidad espacial constituye una respuesta eficaz y del máximo interés. Los objetivos de esta tesis son contribuir a un conocimiento riguroso del edificio, que permita descubrir la particularidad de su entramado espacial y el interés de las soluciones adoptadas en su configuración final, en aras de contrastar su calidad arquitectónica. El edificio de la Central Lechera CLESA, si bien es un edificio muy conocido, lo es de una manera superficial. Aparece en numerosas publicaciones, en muchas ocasiones formando parte de un relato extenso de la obra de su autor. El libro monográfico publicado en 2007 por la Fundación Alejandro de la Sota, cuya edición está a cargo de Teresa Couceiro, es la única publicación específica sobre él. Tras una breve introducción, en la que se destaca la intensa dedicación de Sota a esta obra, reúne una colección de planos, fotografías y croquis, junto a la memoria del proyecto. Ofrece una visión fragmentada, que permite vislumbrar el interés de esta obra, pero no facilita comprenderla en su integridad. Es importante destacar la publicación de CLESA en el libro editado por Pronaos (1989), que incluye una selección, realizada por el autor, de plantas, alzados y secciones que corresponden al proyecto construido junto a fotografías de la obra terminada, además de un breve texto tan conciso como esclarecedor. Sobre Alejandro de la Sota se han escrito, tesis doctorales, numerosos artículos, varios libros así como realizado exposiciones que recogen su obra global, reflejados en este documento en las consiguientes bibliografías específicas. Cabe destacar la exposición realizada en la sede del COAM en 2014, con ocasión de su centenario, que el edificio CLESA protagoniza en cierto modo, por su riesgo de desaparición.2 La tesis se estructura en cuatro capítulos: descripción, análisis, síntesis y conclusiones. El primer capítulo contempla la descripción del edificio objeto de la tesis, con una introducción que nos sitúa en el contexto histórico, económico, cultural y social en el que se desarrolla el encargo, proyecto y obra de la central lechera. La descripción propiamente dicha del conjunto industrial, partiendo del encargo de la central lechera al autor del proyecto, pasando por el anteproyecto, el proyecto visado y llegando a la obra realizada. Se compara el proyecto visado, la obra terminada y la CLESA publicada, así como el devenir del edificio. La segunda parte corresponde al análisis, en primer lugar desde el programa como planteamiento general, estudiando las circulaciones, relaciones espaciales, geométricas, esqueléticas, geográficas -parte a parte- que integran el conjunto de la central. La estructura, introducción explicativa de las soluciones adoptadas por Alejandro de la Sota; análisis del sistema esquelético del edificio por partes, operaciones geométricas y espaciales. Construcción, análisis de la materialización de la obra, sistemas constructivos empleados en cerramientos, cubiertas, lucernarios; de lo general a lo particular, estudiando los sistemas. Finalmente a través de la pequeña escala se compendian elementos singulares que forman parte de sistemas complejos, como las múltiples escaleras, barandillas, carpinterías, miradores. Se recapitula en una síntesis que configura un todo con la suma de las partes, mediante la utilización de recursos de enlace de esa arquitectura aditiva, como es el módulo, los recorridos y los enlaces visuales. El capítulo final de Conclusiones contrasta la hipótesis de partida de la tesis en cuanto a una arquitectura de espacios máximos con recursos mínimos. Recoge también diversas reflexiones como la dialéctica entre el espacio fragmentado y el espacio único; crecimiento expansivo o inclusivo; imagen singular y representación; escala doméstica y escala industrial; renuncias estructurales o limitaciones de medios. Quizás, el mayor interés de esta tesis reside los dibujos realizados en axonométrica del complejo CLESA, que han permitido restituir y reconstruir idealmente la fábrica al inicio de su actividad. Teniendo en cuenta su posible desaparición total o parcial, esta restitución cobra relevancia como testimonio de lo que fue. ABSTRACT The thesis deals with the study of CLESA's Dairy Plant, one of the most significant industrial buildings of the Decade of the fifties in Spain, by Alejandro de la Sota. The Dairies were addressed by Sota at various occasions between 1955 and 1969, being the CLESA plant the only one that is has been built. This is one of the most brilliant exponents of Spanish industrial post-war modern architecture, included in "The architecture industry, IBERIAN DOCOMOMO RECORD"3 between the score of selected buildings of Madrid architecture of this period. It poses a singular solution to achieve the openness of the space required in the implementation of the manufacturing process. The structure of the nave is done with prestressed concrete, being one of the pioneers in the use of this technique. The initial hypothesis considers the reality of the project built from the architecture in response to an industrial program solved with simplicity, that from a resource economy that is inherent, gets from the consistency of the approach, solutions where the space complexity is an effective response of great interest. The objectives of this thesis are to contribute to a rigorous knowledge of the building, which allows to discover the particularity of its space lattice and the interest of the solutions adopted in its final configuration, in order to contrast its architectural quality. The building of the Central Lechera CLESA, despite it is a well known building, is in a superficial way. It appears in several publications, often as part of an extensive account of the work of its author. The monograph published in 2007 by the Foundation Alejandro de la Sota, whose edition is run by Teresa Couceiro, is the only specific publication about it. After a brief introduction, in which Sota's intense dedication to this work stands out, it brings together a collection of drawings, photographs and sketches, along with the project report. It offers a fragmented view, which enable to glimpse the interest of this work, but not helps to understand it in full. It is important to highlight the publication of CLESA in the book edited by Pronaos (1989), which includes a selection made by the author of plants, elevations and sections corresponding to the project built, next to photographs of the finished construction, in addition to a brief text as concise as enlightening. About Alejandro de la Sota have been written doctoral thesis, numerous articles, several books as well as held exhibitions collecting his global work, which have been reflected in this document in the resulting specific bibliographies. It should be noted the exhibition in COAM headquarters in 2014, on the occasion of its Centennial, where the building CLESA has a leading role, in a certain way, because of its risk of disappearance.4 The thesis is structured in four chapters: description, analysis, synthesis, and conclusions. The first chapter provides the description of the building object of this thesis. Includes an introduction that puts us in the historic, economic, cultural and social context in which it is developed the commission, the project and construction of the dairy building. The description itself of the industrial complex, starts with the order of the dairy to the author of the project, moves through the draft, the visa project and reaches the completion of the work. The visa project, CLESA's finished and published work, as well as the future of the building is compared. The second part corresponds to the analysis, first from the program as a general approach, studying the circulations, geometric, spatial, skeletal, geographical relations - bit by bit - comprising the manufacturing plant ("la central"). The structure, explanatory introduction of the solutions adopted by Alejandro de la Sota; analysis of the skeletal system of the building by parts, geometric and spatial operations. Construction, analysis of the realization of the work, constructive systems used in the building enclosures, roofs, skylights; from the general to the particular and studying the systems. Finally through small scale unique elements that are part of complex systems, such as multiple stairs, railings, carpentry, viewpoints are summarized. It is recapitulated in a synthesis which forms a whole with the sum of the parts, using linking resources that belongs to the additive architecture, such as the module, tours and visual links The final chapter of Conclusions contrast the hypothesis of the thesis regarding the maximum space architecture with minimal resources. It also includes various reflections as the dialectic between the fragmented space and the single space; expansive or inclusive growth; unique image and representation; domestic and industrial scale; structural abandonment or limitation of means. Perhaps the greatest interest of this thesis lies in the axonometric drawings made of the CLESA complex, which ideally have allowed to restore and rebuild the factory back to the beginning of its activity. Considering its potential full or partial disappearance, such recovery becomes relevant as a testimonial evidence of what it was.

A general procedure for locating and analyzing protein-binding sequence motifs in nucleic acids

In the last decade, two tools, one drawn from information theory and the other from artificial neural networks, have proven particularly useful in many different areas of sequence analysis. The work presented herein indicates that these two approaches can be joined in a general fashion to produce a very powerful search engine that is capable of locating members of a given nucleic acid sequence family in either local or global sequence searches. This program can, in turn, be queried for its definition of the motif under investigation, ranking each base in context for its contribution to membership in the motif family. In principle, the method used can be applied to any binding motif, including both DNA and RNA sequence families, given sufficient family size.

The Clinical Utility of the Adult Attachment Projective Picture System: A Clinician's Perspective

The Adult Attachment Projective Picture System (AAP) is the first performance- based measure of adult attachment to be developed. The purpose of the measure is to provide a clinical understanding of an adult client's attachment status and associated coping mechanisms. The AAP is a relatively new measure that has yet to be examined from a utility perspective. In the current study, seven psychologists completed a structured survey in order to identify their perspectives of the AAP and its utility as a clinical instrument. A phenomenological qualitative analysis of the data was conducted to derive themes about the AAP and its clinical utility. Analyses aimed to answer the following: What clinical considerations do clinician's focus on when deciding to use this measure? What are common factors among clinician's who do use the measure as well as those who do not? What aspects of the measure are user-friendly and what aspects are difficult? General themes that emerged include (a) the clinical information provided by the AAP is viewed by those who use it as unique and beneficial; (b) time commitment and cost for the clinician are common considerations when clinician's are deciding whether or not to use the AAP or when pursuing training; (c) the AAP provides an increased understanding of one's relational capacities and defenses; and (d) the coding system and transcription process are difficult aspects of the AAP and influence how and/or when it is used. In addition to these themes, multiple respondents discussed potential changes for the AAP that would increase their future use of the instrument. Finally, the implications of these results are discussed.

Digital Curation Program of the Digital Public Library of America (DPLA)

The Digital Public Library of America (DPLA) is a digital library that strives to serve the public through digital collections accumulated from a wide variety of partners. Our chosen topic for the DPLA exhibit project is Perspectives on the Vietnam War. The Vietnam War remains a controversial topic of national interest, making it a topic of depth and of many perspectives. Our goals with this exhibit were to gather different perspectives of the war through personal stories, the media, presidential administrations of the war, military personnel, and the general public, including famous figures. We strove to demonstrate the variety of perspectives on the Vietnam War through a variation of digital objects and content that will be engaging for users: both black and white and color photos, videos, and audio files. Furthermore, we wanted to ensure that our digital materials are of high quality, properly documented, and easy to search and find thus all of our objects are from DPLA and are from usable original sources. This poster will describe our processes for organizational, object selection, building our exhibit, attainment of our goals, and detailed steps of our overall operation. The poster will also include details about the minor issues and bumps that occurred while reaching our final product as well as the team members’ perspectives on the project as a whole including: problems, words to for the wise, and triumphs.

Reducing visual deficits caused by refractive errors in school and preschool children: results of a pilot school program in the Andean region of Apurimac, Peru

Background: Refractive error is defined as the inability of the eye to bring parallel rays of light into focus on the retina, resulting in nearsightedness (myopia), farsightedness (Hyperopia) or astigmatism. Uncorrected refractive error in children is associated with increased morbidity and reduced educational opportunities. Vision screening (VS) is a method for identifying children with visual impairment or eye conditions likely to lead to visual impairment. Objective: To analyze the utility of vision screening conducted by teachers and to contribute to a better estimation of the prevalence of childhood refractive errors in Apurimac, Peru. Design: A pilot vision screening program in preschool (Group I) and elementary school children (Group II) was conducted with the participation of 26 trained teachers. Children whose visual acuity was<6/9 [20/30] (Group I) and≤6/9 (Group II) in one or both eyes, measured with the Snellen Tumbling E chart at 6 m, were referred for a comprehensive eye exam. Specificity and positive predictive value to detect refractive error were calculated against clinical examination. Program assessment with participants was conducted to evaluate outcomes and procedures. Results: A total sample of 364 children aged 3–11 were screened; 45 children were examined at Centro Oftalmológico Monseñor Enrique Pelach (COMEP) Eye Hospital. Prevalence of refractive error was 6.2% (Group I) and 6.9% (Group II); specificity of teacher vision screening was 95.8% and 93.0%, while positive predictive value was 59.1% and 47.8% for each group, respectively. Aspects highlighted to improve the program included extending training, increasing parental involvement, and helping referred children to attend the hospital. Conclusion: Prevalence of refractive error in children is significant in the region. Vision screening performed by trained teachers is a valid intervention for early detection of refractive error, including screening of preschool children. Program sustainability and improvements in education and quality of life resulting from childhood vision screening require further research.

Cobalt-Impregnated Magnetite as General Heterogeneous Catalyst for the Hydroacylation Reaction of Azodicarboxylates

Catalysts consisting of cobalt and nickel impregnated on magnetite have been prepared, characterized and used for the hydroacylation reaction of different azodicarboxylate compounds with aldehydes, using nearly stoichiometric amounts of both reagents in only 3 h. Furthermore, this reaction has been conducted with the smallest amount of catalyst. The cobalt catalyst is stable enough to be removed by magnetic decantation and recycled ten-fold without any detrimental effect on the results.

Effects of a training program to enhance autonomy supportive behaviors among youth soccer coaches

This study aimed to evaluate the prevalence and implementation of a training emphasizing the use of autonomy supportive coaching behaviors among youth soccer coaches in game-play situations as well as evaluating its effects on motivational processes among athletes. Participants included youth sport soccer coaches and their intact teams. Coaches received a series of autonomy-supportive coaching training interventions based on successful programs in general and physical education (Reeve, Jang, Carrell, Jeon & Barch, 2004; Cheon, Reeve & Moon, 2012). Athletes completed questionnaires to assess perceived autonomy support, basic need satisfaction, and motivation (Harris & Watson, 2011). Observations indicated coaches were not able to significantly modify their behaviors, yet reflectively reported modest implementation of autonomy supportive behaviors. Coaches believed the training influenced their coaching style/philosophy in regards to the coach-athlete relationship and communication styles, emphasizing choice and rationales. Continued research is needed to enhance use of autonomy supportive behaviors with volunteer coaches in a youth sport environment.

De Gaulle and Europe: Historical Revision and Social Science Theory. Program for the Study of Germany and Europe Working Paper Series 8.5

The thousands of books and articles on Charles de Gaulle's policy toward European integration, whether written by historians, social scientists, or commentators, universally accord primary explanatory importance to the General's distinctive geopolitical ideology. In explaining his motivations, only secondary significance, if any at all, is attached to commercial considerations. This paper seeks to reverse this historiographical consensus by examining the four major decisions toward European integration during de Gaulle's presidency: the decisions to remain in the Common Market in 1958, to propose the Foucher Plan in the early 1960s, to veto British accession to the EC, and to provoke the "empty chair" crisis in 1965-1966, resulting in the "Luxembourg Compromise." In each case, the overwhelming bulk of the primary evidence-speeches, memoirs, or government documents-suggests that de Gaulle's primary motivation was economic, not geopolitical or ideological. Like his predecessors and successors, de Gaulle sought to promote French industry and agriculture by establishing protected markets for their export products. This empirical finding has three broader implications: (1) For those interesred in the European Union, it suggests that regional integration has been driven primarily by economic, not geopolitical considerations--even in the "least likely" case. (2) For those interested in the role of ideas in foreign policy, it suggests that strong interest groups in a democracy limit the impact of a leader's geopolitical ideology--even where the executive has very broad institutional autonomy. De Gaulle was a democratic statesman first and an ideological visionary second. (3) For those who employ qualitative case-study methods, it suggests that even a broad, representative sample of secondary sources does not create a firm basis for causal inference. For political scientists, as for historians, there is in many cases no reliable alternative to primary-source research.

Clay mineralogy of ODP Site 131-808 sediments

Drill core recovered at Ocean Drilling Program Site 808 (Leg 131) proves that the wedge of trench sediment within the central region of the Nankai Trough comprises approximately 600 m of hemipelagic mud, sandy turbidites, and silty turbidites. The stratigraphic succession thickens and coarsens upward, with hemipelagic muds and volcanic-ash layers of the Shikoku Basin overlain by silty and sandy trench-wedge deposits. Past investigations of clay mineralogy and sand petrography within this region have led to the hypothesis that most of the detritus in the Nankai Trough was derived from the Izu-Honshu collision zone and transported southwestward via axial turbidity currents. Shipboard analyses of paleocurrent indicators, on the other hand, show that most of the ripple cross-laminae within silty turbidites of the outer marginal trench-wedge facies are inclined to the north and northwest; thus, many of the turbidity currents reflected off the seaward slope of the trench rather than moving straight down the trench axis. Shore-based analyses of detrital clay minerals demonstrate that the hemipelagic muds and matrix materials within sandy and silty turbidites are all enriched in illite; chlorite is the second-most abundant clay mineral, followed by smectite. In general, the relative mineral percentages change relatively little as a function of depth, and the hemipelagic clay-mineral population is virtually identical to the turbidite-matrix population. Comparisons between different size fractions (<2 µm and 2-6 µm) show modest amounts of mineral partitioning, with chlorite content increasing in the coarser fraction and smectite increasing in the finer fraction. Values of illite crystallinity index are consistent with conditions of advanced anchimetamorphism and epimetamorphism within the source region. Of the three mica polytypes detected, the 2M1 variety dominates over the 1M and 1Md polytypes; these data are consistent with values of illite crystallinity. Measurements of mica bo lattice spacing show that the detrital illite particles were eroded from a zone of intermediate-pressure metamorphism. Collectively, these data provide an excellent match with the lithologic and metamorphic character of the Izu-Honshu collision zone. Data from Leg 131, therefore, confirm the earlier interpretations of detrital provenance. The regional pattern of sediment dispersal is dominated by a combination of southwest-directed axial turbidity currents, radial expansion of the axial flows, oblique movement of suspended clouds onto and beyond the seaward slope of the Nankai Trough, and flow reflection back toward the trench axis.
