Infrastructure and Economic Growth in Spain, 1845-1935

Between the mid-nineteenth century and the outbreak of the Spanish Civil War in 1936, Spain undertook a sustained process of economic growth and structural change, but was unable to converge with the core European economies.1 The reasons behind Spain"s failure to converge have been a subject of debate among historians for decades. 2 This dissertation aims to analyze the role played by infrastructure in Spanish economic growth during that period, and tries to find out to what extent the potential shortage or inadequacy of the Spanish infrastructure endowment was one of the factors to blame for the country"s nonconvergence. The dissertation draws on recent research on the economic impact of infrastructure, and on the numerous attempts to measure that impact which have been undertaken in the wake of David Aschauer"s work on the United States.

La serie sísmica de Tivissa, 1845 (cadenas costeras catalanas): Los deslizamientos del barranco del Manou

La serie sísmica de Tivissa tuvo lugar durante la lluviosa década de 1840-1850, 21 días después de los aguaceros que ocasionaron graves inundaciones. La serie empezó el 30 de septiembre y finalizó el 14 de octubre. Los terremotos de mayor intensidad ocurrieron el 3 (IEMS-98=VI) y el 7 de octubre (IEMS-98=VI-VII). De acuerdo con la distribución de la información macrosísmica se propone un área epicentral para ambos terremotos entre Tivissa y Vandellòs. El sismo del 7 de octubre indujodeslizamientos de masa al Sur de Tivissa. La estratigrafía, la disposición estructural y la orografía facilitaron estos deslizamientos: tuvieron lugar en una secuencia de capas calcáreas, decimétricas, con interestratos centimétricos de margas que buzan en el mismo sentido que la pendiente de la vertiente del valle, pero menos que ésta, y que está afectada por diaclasas perpendiculares a la estratificación. Ello implica la existencia de masas rocosas aisladas por la estratificación y las diaclasas, susceptibles de deslizarse hacia el valle. El agua de los aguaceros que precedieron a los sismos infiltrada por las diaclasas podría haber facilitado el despegue a nivel de los interestratos margosos. Teniendo en cuenta los datos geológicos y sismológicos se discuten las posibles fuentes de estos terremotos.

Integração RIS/PACS no Hospital das Clínicas de Ribeirão Preto: uma solução baseada em "web"

OBJETIVO: Integração dos Sistemas de Informação em Radiologia (RIS - "Radiology Information System") e de Arquivamento e Comunicação de Imagens (PACS - "Picture Archiving and Communication System") no Serviço de Radiodiagnóstico do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo, para possibilitar a consulta remota de laudos e imagens associadas. MATERIAIS E MÉTODOS: A integração RIS/PACS implementada é feita em tempo real, no momento da consulta, utilizando tecnologias "web" e técnicas de programação para "intranet/internet". RESULTADOS: A aplicação "web" permite a consulta pela "intranet" do hospital dos laudos de exames e imagens associadas através de nome, sobrenome, número de registro hospitalar dos pacientes ou por modalidade, dentro de um determinado período. O visualizador possibilita que o usuário navegue pelas imagens, podendo realizar algumas funções básicas como "zoom", controle de brilho e contraste e visualização de imagens lado a lado. CONCLUSÃO: A integração RIS/PACS diminui o risco de inconsistências, através da redução do número de interfaces entre bases de dados com grande redundância de informação, proporcionando um ambiente de trabalho rápido e seguro para consulta de laudos radiológicos e visualização de imagens associadas.

Spermiogenesis and spermatozoon ultrastructure of the dilepidid cestode Molluscotaenia crassiscolex (von Linstow, 1890), an intestinal parasite of the common shrew Sorex araneus

Spermiogenesis in Molluscotaenia crassiscolex begins with the formation of a differentiation zone containing two centrioles. One of the centrioles develops a flagellum directly into the cytoplasmic extension. The nucleus elongates and later migrates along the spermatid body. During advanced stages of spermiogenesis, a periaxonemal sheath appears in the spermatid. Spermiogenesis finishes with the appearance of a single helicoidal crested body at the base of the spermatid and, finally, the narrowing of the ring of arched membranes causes the detachment of the fully formed spermatozoon. The mature spermatozoon of M. crassiscolex exhibits a partially detached crested body in the anterior region of the spermatozoon, one axoneme, twisted cortical microtubules, a periaxonemal sheath, and a spiralled nucleus. The anterior spermatozoon extremity is characterized by the presence of an electron-dense apical cone and a single spiralled crested body, which is attached to the sperm cell in the anterior and posterior areas of region I, whereas in the middle area it is partially detached from the cell. This crested body is described for the first time in cestodes. The posterior extremity of the male gamete exhibits only the disorganizing axoneme. Results are discussed and compared particularly with the available ultrastructural data on dilepidids sensu lato.

A Pragmatic Intellectual: Dutch Fabians, Boekman, and Cultural Policy in the Netherlands, 1890-1940

Around 1900, the notion of community art (gemeenschapskunst) served to crystallize Dutch social democratic thinking about the role of the arts in society. Drawing on the pragmatism of leading social democrats like Wibaut, and drawing on his formal education in economics and statistics, the self‐made social democrat Emanuel Boekman redressed the utopian meaning of community art to signify the dissemination of "good" culture over all layers of society in his influential 1939 dissertation on the relation of the state to the arts. Being about facts rather than opinions, Boekman set the boundaries of his work to exclude a substantial discussion of the meaning of "good" culture. On the one hand, this pragmatism helped Boekman to gain support for government intervention for the arts over most of the political spectrum. On the other hand, Boekman thus pre‐empted discussions about the tension between "quality" and "accessibility" of the arts that haunts cultural policy in the Netherlands to this day.

Determinação de carbaril utilizando testes ELISA (Enzyme-linked immunosorbent assay) e CLAE com detecção por arranjo de diodos

ELISAs have been applied to pesticide residue analysis due to their high sensitivity and selectivity. However, some ELISAs performance may be affected by matrix components. In this work, ELISA for carbaryl in water samples was checked for interference by naturally occurring fulvic acids. The results suggested that the high fulvic acid concentration (ž³30 mg L-1) and acidic pH conditions (pH 4.0) interfere with the signal detection decreasing the method sensitivity. A dilution of the samples and adjust to pH 8.0 are appropriate to minimize the matrix interferences in the ELISA method. Good correlation between ELISA and HPLC-DAD results was observed.

Filmes de diamante CVD dopado com boro. Parte I . Histórico, produção e caracterização

This review presents a brief account concerning the production, characterization and evolution of the knowledge in the area of diamond and boron-doped diamond films. The most important methods used for the growth of these films, such as chemical vapor deposition and high pressure/high temperature systems, as well as the several kinds of reactors which can be employed are reviewed. However, larger emphasis is given to the CVD method. Morphological, structural and electric properties of these films, as well as their role in the performance of voltammetric electrodes for electrochemistry and electroanalytical chemistry are also discussed.

Distribuição de mercúrio em diferentes solos da Bacia do médio Rio Negro-AM: influência da matéria orgânica no ciclo biogeoquímico do mercúrio

Soils play an important role in the biogeochemical cycle of mercury as a sink for and source of this metallic species to atmospheric and hydrological compartments. In the study reported here, various types of soil were evaluated to ascertain the influence of parameters such as pH, organic matter content, Fe, Al, sand, silt, clay, C/H, C/N, C/O atomic ratios, and cation exchange capacity on the distribution of Hg in Amazonia's mid-Negro River basin. The data obtained were interpreted by multivariate exploratory analyses (hierarchical cluster analysis and principal component analysis), which indicated that organic matter plays an important role in mercury uptake in the various soils studied. The soils in floodable areas were found to contain 1.5 to 2.8-fold higher Hg concentrations than those in non-floodable areas. Since these soils are flooded almost year-round, they are less available to participate in redox processes at the soil/atmosphere interface. Hence, floodable areas, which comprise humic-rich soils, accumulate more mercury than non-floodable soils, thus playing an important role in the biogeochemical cycle of Hg in Amazonia's mid-Negro River basin.

Educação ambiental nas escolas da região de Ribeirão Preto (SP): concepções orientadoras da prática docente e reflexões sobre a formação inicial de professores de química

During short courses, 95 secondary school teachers from 49 state schools and 421 students from the Ribeirão Preto region (in Sao Paulo state, Brazil, with a population of 530,000) were asked to fill in different questionnaires. The points raised in the teacher's questionnaire were used as a guide to establish a continuous dialogue during the short courses. Most of the schools claimed to have some kind of environmental education (EE). Based on the questionnaires and dialogues we analyzed how the teachers' perceptions on EE reflect on the views secondary students hold about their own responsibility for preserving the environment. The role of universities in the preparation of chemistry teachers capable of effectively approaching EE is also discussed.

Distribuição e biodisponibilidade de crômio em solos contaminados por resíduos de couro

Samples of soil, water and sediment were collected and analyzed in order to evaluate chromium contamination due to deposition of tannery residues onto soils under different management regimes. The results showed that soils used for sugar cane cultivation were not adversely impacted. However, in the case of mango plantations, variable concentrations of chromium were measured in the soil profile, with 22.2% of values being higher than permitted legal limits, and 38.9% being at levels requiring remediation. Concentrations of bioavailable chromium were lower than the detection limit of the method (0.01 mg of chromium kg-1 of soil), indicating that all of the chromium present in the samples was either complexed or in an insoluble form. Chromium concentrations measured in samples of water and sediments were indicative of low mobility of the metal in soils. The main cause of differences found between soil samples obtained from different cultivations was the type of soil management.
