Sarcoidosis, a propósito de 68 casos

La sarcoidosis es una enfermedad sistémica, granulomatosa de etiología desconocida que afecta al adulto joven. Puede interesar a cualquier órgano aunque también existen formas asintomáticas. En este trabajo se describen las características clínicas, el tratamiento y la evolución de una serie de pacientes diagnosticados de sarcoidosis. Es un estudio retrospectivo en un hospital universitario con un área de referencia de 700.000 habitantes. La manifestación de inicio más frecuente fue el síndrome de Löfgren. La mayoría de los pacientes recibieron tratamiento con antiinflamatorios esteroideos y no esteroideos y presentaron una buena evolución, con resolución de la enfermedad.

Informe sobre el tercer DLM-Forum on Electronic Records (Barcelona, 6¿8 de maig de 2002)

Del 6 al 8 de maig de 2002 es va celebrar a Barcelona la tercera edició del DLM-Forum on Electronic Records, el fòrum internacional multidisciplinari que té per objectiu la millora de la gestió dels documents electrònics a les organitzacions i conservació a llarg termini. Aquesta edició ha estat marcada per una participació més activa de la indústria de les tecnologies de la informació i de les comunicacions, i per la presentació dels resultats d'iniciatives del DLM-Forum 1996. El present informe descriu la gènesi i el desenvolupament del DLM-Forum de Barcelona, i n'indica els assoliments més remarcables.

The first SEPServer event catalogue 68-MeV solar proton events observed at 1 AU in 1996-2010

SEPServer is a three-year collaborative project funded by the seventh framework programme (FP7-SPACE) of the European Union. The objective of the project is to provide access to state-of-the-art observations and analysis tools for the scientific community on solar energetic particle (SEP) events and related electromagnetic (EM) emissions. The project will eventually lead to better understanding of the particle acceleration and transport processes at the Sun and in the inner heliosphere. These processes lead to SEP events that form one of the key elements of space weather. In this paper we present the first results from the systematic analysis work performed on the following datasets: SOHO/ERNE, SOHO/EPHIN, ACE/EPAM, Wind/WAVES and GOES X-rays. A catalogue of SEP events at 1 AU, with complete coverage over solar cycle 23, based on high-energy (~68-MeV) protons from SOHO/ERNE and electron recordings of the events by SOHO/EPHIN and ACE/EPAM are presented. A total of 115 energetic particle events have been identified and analysed using velocity dispersion analysis (VDA) for protons and time-shifting analysis (TSA) for electrons and protons in order to infer the SEP release times at the Sun. EM observations during the times of the SEP event onset have been gathered and compared to the release time estimates of particles. Data from those events that occurred during the European day-time, i.e., those that also have observations from ground-based observatories included in SEPServer, are listed and a preliminary analysis of their associations is presented. We find that VDA results for protons can be a useful tool for the analysis of proton release times, but if the derived proton path length is out of a range of 1 AU < s[3 AU, the result of the analysis may be compromised, as indicated by the anti-correlation of the derived path length and release time delay from the asso ciated X-ray flare. The average path length derived from VDA is about 1.9 times the nominal length of the spiral magnetic field line. This implies that the path length of first-arriving MeV to deka-MeV protons is affected by interplanetary scattering. TSA of near-relativistic electrons results in a release time that shows significant scatter with respect to the EM emissions but with a trend of being delayed more with increasing distance between the flare and the nominal footpoint of the Earth-connected field line.

Edificio de 68 viviendas en el 22@ Barcelona

A partir de una volumetría marcada y definida, el proyecto consta de 68 viviendas de 70m2 repartidas en pb+6 y pb+11 en la parte de la torre. Se propone una planta tipo clara con una franja central de núcleo de servicios. Esto se consigue mediante pequeños recortes en la fachada que dan juegos de luz y color a la pieza estableciendo diferencias entre los alzados los cuales, a su vez,recuperan el uso de la ventana horizontal.
