A finite element method for the Saint-Venant torsion and bending problems for prismatic beams

In this work, we present a finite element formulation for the Saint-Venant torsion and bending problems for prismatic beams. The torsion problem formulation is based on the warping function, and can handle multiply-connected regions (including thin-walled structures), compound and anisotropic bars. Similarly, the bending formulation, which is based on linearized elasticity theory, can handle multiply-connected domains including thin-walled sections. The torsional rigidity and shear centers can be found as special cases of these formulations. Numerical results are presented to show the good coarse-mesh accuracy of both the formulations for both the displacement and stress fields. The stiffness matrices and load vectors (which are similar to those for a variable body force in a conventional structural mechanics problem) in both formulations involve only domain integrals, which makes them simple to implement and computationally efficient.

Imaginario y realidad de la muerte de Santa María Egipciaca en el contexto castellano de la crisis del siglo XIV

Resumen: El presente trabajo se propone analizar el sentido y la funcionalidad del tema de la muerte del santo en el contexto de la crisis que afecta a Europa en el siglo XIV, a través de la muerte de Santa María Egipciaca –una de las santas medievales más populares– narrada en la Vida de Santa María Egipciaca, un poema castellano compuesto en el temprano siglo XIII pero transmitido a fines del siglo XIV en el manuscrito K-III-4 de la Biblioteca de San Lorenzo de El Escorial.

La segunda coronación de la Virgen de Luján : robo de la corona y peregrinación de desagravio (1897)

Resumen: En el presente artículo el autor se ocupa de reseñar las circunstancias que rodearon el robo de la corona de la Virgen de Luján, bendecida por el papa León XIII en 1887. Diez años después de la solemne fiesta de la coronación pontificia esta primorosa joya, confeccionada por el acreditado orfebre parisino Poussielgue-Rusand, fue sustraída del camarín donde se veneraba la Sagrada Imagen. La recuperación y restitución motivó la organización de una multitudinaria peregrinación al Santuario de Luján que puso de manifiesto la profunda devoción del pueblo argentino a su Patrona.

Teología mística de Gonzalo de Berceo

Resumen: El propósito de este trabajo es demostrar que el sentido esencial de la Introducción de los Milagros de Nuestra Señora de Gonzalo de Berceo consiste en la brevísima exposición poética de una especial teología mística diferente tanto de la mística especulativa cristiana medieval occidental de origen platónico o neoplatónico como de la mística amorosa cristiana occidental que tiene origen en el Cantar de los Cantares y en sus comentarios antiguos y medievales, y que esta teología mística de Gonzalo de Berceo se basa en la función mediadora de la Virgen María y en su carácter de Madre de Dios.

Una presencia que conoce : mensajes de Juan Pablo II para la Jornada Mundial del Enfermo

El artículo “Una presencia que conoce” presenta una parte del trabajo que el autor realizó sobre los mensajes del papa Juan Pablo II para la Jornada Mundial del Enfermo y que próximamente se podrá conocer con el título “El amor de los que sufren” publicado por Ed. San Benito con prólogo de la Dra. Beatriz Balián de Tagtachian. El profundo estudio de los trece Mensajes del Santo Padre para la Jornada Mundial del Enfermo analiza qué concepto de enfermo tiene el papa Juan Pablo II, cuáles son sus presupuestos antropológicos y qué sentido tiene la enfermedad en el plan de Dios sobre cada uno de los hombres; cuál es la misión de la Iglesia, y qué tipo de acompañamiento necesitan los enfermos para que podamos imitar la solicitud de la Virgen María. En estas páginas se aborda el significado y la finalidad de la Jornada Mundial del Enfermo, la importancia que el Papa atribuye a ésta para la misión de la Iglesia en el mundo, los objetivos que él ha determinado para esta jornada y el modo de celebrarla que ha sugerido.

Fish assemblages and benthic habitats of Buck Island Reef National Monument (St. Croix, U.S. Virgin Islands) and the surrounding seascape: A characterization of spatial and temporal patterns

Since 1999, NOAA’s Biogeography Branch of the Center for Coastal Monitoring and Assessment (CCMA-BB) has been working with federal and territorial partners to characterize, monitor, and assess the status of the marine environment around northeastern St. Croix, U.S. Virgin Islands. This effort is part of the broader NOAA Coral Reef Conservation Program’s (CRCP) National Coral Reef Ecosystem Monitoring Program (NCREMP). With support from CRCP’s NCREMP, CCMA conducts the “Caribbean Coral Reef Ecosystem Monitoring project” (CREM) with goals to: (1) spatially characterize and monitor the distribution, abundance, and size of marine fauna associated with shallow water coral reef seascapes (mosaics of coral reefs, seagrasses, sand and mangroves); (2) relate this information to in situ fine-scale habitat data and the spatial distribution and diversity of habitat types using benthic habitat maps; (3) use this information to establish the knowledge base necessary for enacting management decisions in a spatial setting; (4) establish the efficacy of those management decisions; and (5) develop data collection and data management protocols. The monitoring effort in northeastern St. Croix was conducted through partnerships with the National Park Service (NPS) and the Virgin Islands Department of Planning and Natural Resources (VI-DPNR). The geographical focal point of the research is Buck Island Reef National Monument (BIRNM), a protected area originally established in 1961 and greatly expanded in 2001; however, the work also encompassed a large portion of the recently created St. Croix East End Marine Park (EEMP). Project funding is primarily provided by NOAA CRCP, CCMA and NPS. In recent decades, scientific and non-scientific observations have indicated that the structure and function of the coral reef ecosystem around northeastern St. Croix have been adversely impacted by a wide range of environmental stressors. The major stressors have included the mass Diadema die off in the early 1980s, a series of hurricanes beginning with Hurricane Hugo in 1989, overfishing, mass mortality of Acropora corals due to disease and several coral bleaching events, with the most severe mass bleaching episode in 2005. The area is also an important recreational resource supporting boating, snorkeling, diving and other water based activities. With so many potential threats to the marine ecosystem and a dramatic change in management strategy in 2003 when the park’s Interim Regulations (Presidential Proclamation No. 7392) established BIRNM as one of the first fully protected marine areas in NPS system, it became critical to identify existing marine fauna and their spatial distributions and temporal dynamics. This provides ecologically meaningful data to assess ecosystem condition, support decision making in spatial planning (including the evaluation of efficacy of current management strategies) and determine future information needs. The ultimate goal of the work is to better understand the coral reef ecosystems and to provide information toward protecting and enhancing coral reef ecosystems for the benefit of the system itself and to sustain the many goods and services that it offers society. This Technical Memorandum contains analysis of the first six years of fish survey data (2001-2006) and associated characterization of the benthos (1999-2006). The primary objectives were to quantify changes in fish species and assemblage diversity, abundance, biomass and size structure and to provide spatially explicit information on the distribution of key species or groups of species and to compare community structure inside (protected) versus outside (fished) areas of BIRNM.

The ecological basis of fishery yield of the Puerto Rico-Virgin Islands Insular Shelf: 1987 Assessment

A literature review was conducted to locate information on the flow of energy from primary producers to the fishery stocks of the Puerto Rican-Virgin Islands insular shelf. This report uses site-specific information to describe the major ecological subsystems, or habitats, of the region, to identify the more common species and the subsystems in which they occur, to quantify productivity and biomass, and to outline trophic relationships. Discussions on each topic and subsystem vary in substance and detail, being limited by the availability and accessibility of information. (PDF contains 189 pages) Seven distinct subsystems are described: mangrove estuary, seagrass bed, coral reef, algal plain, sand/mud bottom, shelf break, and overlying pelagic. Over 50 tables provide lists of species found in each habitat on various surveys dating back to 1956. Estimates of density, relative abundance, and productivity are provided when possible. We evaluated whether sufficient information exists to support an analysis of the energy basis of fishery production in the area, beginning with the design and development of an ecosystem model. Data needs in three categories - species lists, biomass, and trophic relations - were examined for each subsystem and for each of three species groups - primary producers, invertebrates, and fish. We concluded that adequate data, sufficient for modeling purposes, are available in 16 (25%) of 64 categories; limited data, those requiring greater extrapolation, are available in 35 (55%) categories; and no data are available in 13 (20%) categories. The best-studied subsystems are seagrass beds and coral reefs, with at least limited data in all categories. Invertebrates, the intermediate link in the food web between primary producers and fishes, are the least quantified group in the region. Primary production and fishes, however, are relatively well-studied, providing sufficient data to support an ecosystem-level analysis and to initiate a modeling effort.

Prevalência de HPV em adolescentes virgens e com atividade sexual

O Papilomavírus humano (HPV) é um vírus DNA bastante prevalente em estimativas mundiais, sendo a DST isolada mais frequente no mundo. Existem poucos dados sobre prevalência em adolescentes sem vida sexual ativa, havendo ainda muitos tabus nesta faixa etária. O presente estudo tem por objetivo identificar a prevalência de Papilomavírus humano através de biologia molecular em pacientes sem coitarca, comparando com um grupo de pacientes da mesma faixa etária com atividade sexual. Foram avaliadas 100 adolescentes com idade variando de 11 a 20 anos, com pelo menos dois anos pós-menarca, atendidas no período de janeiro de 2007 a janeiro de 2009 no ambulatório de ginecologia infantopuberal do Hospital Universitário Pedro Ernesto. Das 100 adolescentes, 50 apresentavam hímen íntegro e 50 relatavam atividade sexual regular. Para as pacientes sem coitarca (grupo 1) foi realizada uma coleta apenas de vestíbulo e para as pacientes com atividade sexual (grupo 2) foi realizada coleta de vagina e endocérvice. A pesquisa de DNA-HPV foi realizada por captura híbrida de 2 geração. Os resultados foram descritos em unidade relativa de luz. Para os dados categóricos foram aplicados os testes exato de Fisher. A positividade geral de DNA de HPV de alto e de baixo risco foi de 72%. No grupo 1 houve positividade do teste em 3 casos (6%). Já no grupo 2, 33 casos (66%) foram positivos para pelo menos um sítio. Material de vagina foi positivo em 30 casos (60%) e de colo em 27 casos (54%). Pode-se concluir que a positividade nas meninas com vida sexual ativa é alta. A infecção pelo HPV, ainda que pouco frequente, pode estar presente em meninas sem coitarca.

Herpetofaunal Inventories of the National Parks of South Florida and the Caribbean: Volume II. Virgin Islands National Park

Amphibian declines and extinctions have been documented around the world, often in protected natural areas. Concern for this alarming trend has focused attention on the need to document all species of amphibians that occur within U.S. National Parks and to search for any signs that amphibians may be declining. This study, an inventory of amphibian species in Virgin Islands National Park, was conducted from 2001 to 2003. The goals of the project were to create a georeferenced inventory of amphibian species, use new analytical techniques to estimate proportion of sites occupied by each species, look for any signs of amphibian decline (missing species, disease, die-offs, etc.), and to establish a protocol that could be used for future monitoring efforts. Several sampling methods were used to accomplish these goals. Visual encounter surveys and anuran vocalization surveys were conducted in all habitats throughout the park to estimate the proportion of sites or proportion of area occupied (PAO) by amphibian species in each habitat. Line transect methods were used to estimate density of some amphibian species and double observer analysis was used to refine counts based on detection probabilities. Opportunistic collections were used to augment the visual encounter methods for rare species. Data were collected during four sampling periods and every major trail system throughout the park was surveyed. All of the amphibian species believed to occur on St. John were detected during these surveys. One species not previously reported, the Cuban treefrog (Osteopilus septentrionalis), was also added to the species list. That species and two others (Eleutherodactylus coqui and Eleutherodactylus lentus) bring the total number of introduced amphibians on St. John to three. We detected most of the reptile species thought to occur on St. John, but our methods were less suitable for reptiles compared to amphibians. No amphibian species appear to be in decline at this time. We found no evidence of disease or of malformations. Our surveys provide a snapshot picture of the status of the amphibian species, so continued monitoring would be necessary to determine long-term trends, but several potential threats to amphibians were identified. Invasive species, especially the Cuban treefrog, have the potential to decrease populations of native amphibians. Introduced mammalian predators are also a potential threat, especially to the reptiles of St. John, and mammalian grazers might have indirect effects on amphibians and reptiles through habitat modification. Finally, loss of habitat to development outside the park boundary could harm some important populations of amphibians and reptiles on the island.

A peregrinação ocidental no teatro de Afonso Álvares (XVI) e Xavier Lama (século XX)

Esta dissertação tem por objetivo mostrar como o mito de São Tiago Maior e a peregrinação religiosa na Idade Média são retratados na dramaturgia portuguesa e galega. Para isso, reporta-se a duas obras: Auto de Santiago de Afonso Álvares (Portugal - séc. XVI) e O Peregrino errante que cansou ó demo de Xavier Lama (Galícia séc. XX). Objetiva verificar como os discursos das personagens, associados aos demais elementos que estruturam as obras, têm por finalidade acentuar a importância, no contexto da religiosidade ibérica, do culto à Virgem de Guadalupe e de São Tiago em sua tríplice representação: São Tiago Apóstolo, Peregrino ou Mata-mouros. E, sobretudo, demonstrar o caráter doutrinador e moralizante das peças, principalmente na recomendação das virtudes a serem seguidas e dos pecados a serem evitados pelo cristão em sua peregrinação existencial, objetivando a ascenção espiritual

Silenced angels: an obscure Saint Theresa in George Eliots Middlemarch

A presente dissertação objetiva a comparação proposta no Prelúdio do romance Middlemarch por sua autora George Eliot entre a protagonista da obra, Dorothea Brooke, e a figura histórica Teresa dÁvila. A partir de tal estudo, busca-se compreender de que modo a situação específica da mulher na Era Vitoriana é articulada no romance de modo a espelhar a crise ontológica e epistemológica do próprio ser humano diante das transformações consolidadas com o Iluminismo e as revoluções liberais do século XVIII que culminariam na morte de Deus. Dorothea mostra-se uma cristã tão fervorosa quanto a Teresa quinhentista, mas faltam-lhe certezas e a resolução para concretizar as reformas sociais que defende, pois ela encarna o mito de feminilidade oitocentista batizado de Anjo do Lar ideal de sujeição feminina à ordem falocêntrica cujas funções são a proteção e difusão da moralidade burguesa e a substituição de elementos cristãos no universo do sagrado a uma sociedade cada vez mais materialista e insegura de valores absolutos. As aflições de Dorothea representam as aflições da mulher vitoriana, mas o momento crítico desta mulher reflete, em Middlemarch, uma crise muito maior do Ocidente, que teve início com a Era da Razão
