Recommendations on seismic actions on bridges

The paper describes the main features of a technical Recommendation first draft on Seismic Actions on Bridges, promoted by the Spanish Ministry of Public Works (MOPT). Although much more research is needed to clarify the seismic behaviour of the vast class of problems present in port structures the current state of the art allows at least a classificaton of subjects and the establishment of minimum requirements to guide the design. Also the use of more refined methods for specially dangerous situations needs some general guidelines that contribute to mantein the design under reasonable safety margins. The Recommendations of the Spanish MOPT are a first try in those directions

Innovación en el diseño de centrales hidroeléctricas a principios de siglo XX. La ingeniería arquitectura de Casto Fernández-Shaw en la presa de La Jándula

The power plant location in the first hydroelectrial dams was a relevant issue at the end of XIX century and early XX. Different solutions were tried, some of them with very interesting aesthetics results and hydraulic and structural implications. Such is the case of La Jándula dam, inaugurated in 1930, that includes the power station inside the dam. This article examines the possible national and international inspirations of this singular solution, corroborating the hypothesis of its unprecedented nature. The collaboration of the architect Casto Fernández-Shaw in the design and integration of the engine room was decisive, because it achieved a result of an aesthetic quality and formal expressiveness unprecedented in a work of hydraulic engineering, as well as the birth of a style Shaw himself defined as architectural engineering.La ubicación de la sala de máquinas fue un factor relevante en las primeras presas hidroeléctricas de finales del siglo XIX y principios del XX, que originó el ensayo de distintas soluciones, algunas de ellas con resultados estéticos e implicaciones hidráulicas y estructurales de gran interés. Tal es el caso de la presa de La Jándula, inaugurada en 1930, que incorporaba la central en el seno del cuerpo de presa. El artículo indaga los posibles antecedentes nacionales e internacionales de esta solución tan singular, corroborando la hipótesis de su carácter inédito. La colaboración del arquitecto Casto Fernández- Shaw en el diseño e integración de la sala de máquinas fue decisiva, ya que logró un resultado de una calidad estética y una expresividad formal sin precedentes en una obra de ingeniería hidráulica, así como el nacimiento de un estilo que el propio Shaw definiría como ingeniería arquitectura

Consensus document on allergic conjunctivitis (DECA)

Allergic conjunctivitis (AC) is an inflammatory disease of the conjunctiva caused mainly by an IgE-mediated mechanism. It is the most common type of ocular allergy. Despite being the most benign form of conjunctivitis, AC has a considerable effect on patient quality of life, reduces work productivity, and increases health care costs. No consensus has been reached on its classification, diagnosis, or treatment. Consequently, the literature provides little information on its natural history, epidemiological data are scarce, and it is often difficult to ascertain its true morbidity. The main objective of the Consensus Document on Allergic Conjunctivitis (Documento dE Consenso sobre Conjuntivitis Alérgica [DECA]), which was drafted by an expert panel from the Spanish Society of Allergology and Spanish Society of Ophthalmology, was to reach agreement on basic criteria that could prove useful for both specialists and primary care physicians and facilitate the diagnosis, classification, and treatment of AC. This document is the first of its kind to describe and analyze aspects of AC that could make it possible to control symptoms

Informe: Derecho del trabajo y de la seguridad social en España en 2013. Algunos puntos críticos

Este documento intenta reflejar algunos de los principales cambios y novedades del ordenamiento laboral español en 2013, levantando acta de cómo la mutabilidad de nuestro Derecho del Trabajo es imparable. Este informe, consciente de ello, ofrece una selección de elementos esenciales, a juicio de sus autores, especialistas en cada una de las materias, encuadrados en la Sección Juvenil de la Asociación Española de Derecho del Trabajo y de la Seguridad Social. En él, conforme a la organización de dicha Sección en grupos de trabajo, se abordan las novedades más relevantes en materia de derechos fundamentales inespecíficos, contratación laboral, vicisitudes del contrato de trabajo, Derecho colectivo, conciliación y corresponsabilidad, protección social y prevención de riesgos laborales. This paper tries to show some of the many changes and novelties in Spanish Labour Law during 2013, drawing up a record of the unstoppable character of our Labour legal system. This report offers a selection of essential elements, according to its authors, all of them specialists in each one of the subjects, being part of the Young Scholars’ Section of the Spanish Association for Labour and Social Security Law. According to the organization of the said Section in working groups, we can find novelties concerning unspecific fundamental rights, work contracts, the life of the work contract and collective Labour Law, reconciliation and co responsibility, social protection and occupational risk prevention

Performance Characteristics of OpenMP Language Constructs on a Many-core-on-a-chip Architecture

Recent emerging many-core-on-a-chip architectures present massive on-chip parallelism through hardware support for multithreading. In order to achieve fast development of parallel applications that exploit this massive intrachip parallelism to achieve highly sustainable performance, suitable programming models are needed. OpenMP, the industry de facto standard for writing parallel programs on shared memory systems, could become a reasonable candidate

Landing OpenMP on Cyclops-64: An Efficient Mapping of OpenMP to a Many-Core System-on-a-Chip

This paper presents our experience mapping OpenMP parallel programming model to the IBM Cyclops-64 (C64) architecture. The C64 employs a many-core-on-a-chip design that integrates processing logic (160 thread units), embedded memory (5MB) and communication hardware on the same die. Such a unique architecture presents new opportunities for optimization. Specifically, we consider the following three areas: (1) a memory aware runtime library that places frequently used data structures in scratchpad memory; (2) a unique spin lock algorithm for shared memory synchronization based on in-memory atomic instructions and native support for thread level execution; (3) a fast barrier that directly uses C64 hardware support for collective synchronization. All three optimizations together, result in an 80% overhead reduction for language constructs in OpenMP. We believe that such a drastic reduction in the cost of managing parallelism makes OpenMP more amenable for writing parallel programs on the C64 platform
