    OBJECTIVES: To describe trends in fertility, fetal death rate, prematurity and low birth weight, as well as their association with advanced maternal age, in Spain from 1996 to 2005. METHODS: We performed an ecological study. The association between low birth weight and prematurity with maternal age was analyzed through contingency tables. The pattern of fetal mortality rate was analyzed through direct standardization. To study the risk of late fetal mortality, adjusted by age and prematurity, a Poisson regression model was used. RESULTS: The rates of fertility and late fetal mortality increased in women aged more than 35 years, especially in women aged more than 45 years. The risk of late fetal mortality was 2.7 times higher in women aged 45 years and above (rate ratio, 2.7; 95%CI: 1.8-3), with an etiological fraction of exposure of 69% (95%CI: 55.2-78.6). The prevalence rate of prematurity and low birth weight was three times higher in this age group, with a prevalence rate of prematurity of 2.9 (95%CI: 2.7-3.1) and of low birth weight of 3.1 (95%CI: 2.9-3.3). CONCLUSIONS: The high risk found in women aged more than 45 years is explained by the increase in the proportion of pregnancies within this age group during the period analyzed. Further studies in perinatal epidemiology that analyze the impact of assisted reproduction techniques in pregnancies in older women are required, as well as a national registry of assisted reproduction techniques

    Model Based Development of Quality-Aware Software Services

    Modelling languages and development frameworks give support for functional and structural description of software architectures. But quality-aware applications require languages which allow expressing QoS as a first-class concept during architecture design and service composition, and to extend existing tools and infrastructures adding support for modelling, evaluating, managing and monitoring QoS aspects. In addition to its functional behaviour and internal structure, the developer of each service must consider the fulfilment of its quality requirements. If the service is flexible, the output quality depends both on input quality and available resources (e.g., amounts of CPU execution time and memory). From the software engineering point of view, modelling of quality-aware requirements and architectures require modelling support for the description of quality concepts, support for the analysis of quality properties (e.g. model checking and consistencies of quality constraints, assembly of quality), tool support for the transition from quality requirements to quality-aware architectures, and from quality-aware architecture to service run-time infrastructures. Quality management in run-time service infrastructures must give support for handling quality concepts dynamically. QoS-aware modeling frameworks and QoS-aware runtime management infrastructures require a common evolution to get their integration

    Fractional-step methods and finite elements with symmetric stabilization for the transient Oseen problem

    Get PDF
    International audienceThis paper deals with the spatial and time discretization of the transient Oseen equations. Finite elements with symmetric stabilization in space are combined with several time-stepping schemes (monolithic and fractional-step). Quasi-optimal (in space) and optimal (in time) error estimates are established for smooth solutions in all flow regimes. We first analyze monolithic time discretizations using the Backward Differentation Formulas of order 1 and 2 (BDF1 and BDF2). We derive a new estimate on the time-average of the pressure error featuring the same robustness with respect to the Reynolds number as the velocity estimate. Then, we analyze fractional-step pressure-projection methods using BDF1. The stabilization of velocities and pressures can be treated either implicitly or explicitly. Numerical results illustrate the main theoretical findings

    El Proyecto Cartovirtual: Cartoteca Nacional Histórica Virtual

    Get PDF
    El Proyecto CartoVIRTUAL propone el desarrollo de soluciones para el acceso vía Internet a los fondos distribuidos de las cartotecas hispano-lusas, con el objetivo de promocionar la publicación del patrimonio cartográfico y facilitar el trabajo de investigadores y documentalistas. Para ello, se utilizan los estándares y servicios de las Infraestructuras de Datos Espaciales (IDE) y se desea diseminar los contenidos académicos a través de plataformas educativas. Se pretende implementar un prototipo de Cartoteca Histórica Virtual distribuida con las ventajas de las cartotecas reales, que disponga de servicios interoperables, gratuitos y de código abierto para la búsqueda y el acceso al contenido histórico. Más allá del acceso a los recursos y de la simple visualización de los documentos, se están desarrollando nuevas herramientas online para su estudio, favoreciendo la preservación de los fondos y limitando su acceso físico. En este artículo se presentan los avances tecnológicos desarrollados hasta la fecha y los nuevos retos que quedan por resolver

    [Fertility in Spain, 1996-2006: foreign versus Spanish women].

    Get PDF
    OBJECTIVES: To determine fertility trends in Spain and whether women's specific fertility rates differ by age and nationality during the period 1996-2006. METHODS: We performed a population-based, cross-sectional study. Direct standardization was used to compare fertility rates by nationality. Foreign versus Spanish women's fertility rates by age and the period under review were compared by a generalized linear model. The trend by nationality was described by time plots and was analyzed by simple linear regression models. RESULTS: Foreign women had more children (total fertility rate: 2 versus 1.2) and at younger age. The upward trend observed in the fertility of Spanish women (p<0.001) was primarily due to increased fertility in older mothers (35 years and older). The fertility of foreign women aged < or =19 was six times higher than that of Spanish women (rate ratio: 6.00, 95% CI: 2.60-13.86). CONCLUSIONS: The fertility pattern of foreign women differs from that of Spanish women and is mainly characterized by higher fertility, especially in younger women (< or =19 years). This pattern may be associated with social and cultural differences. Prevention and sexual educational policies should be reformulated to take into account the specific sociocultural characteristics of this group and to adapt prevention messages to their cultural context

    Robin Based Semi-Implicit Coupling in Fluid-Structure Interaction: Stability Analysis and Numerics

    Get PDF
    International audienceIn this report, we propose a semi-implicit coupling scheme for the numerical simulation of fluid-structure interaction systems involving a viscous incompressible fluid. The scheme is stable irrespectively of the so-called added-mass effect and allows for conservative time-stepping within the structure. The efficiency of the scheme is based on the explicit splitting of the viscous effects and geometrical/convective non-linearities, through the use of the Chorin-Temam projection scheme within the fluid. Stability comes from the implicit pressure-solid coupling and a specific Robin treatment of the explicit viscous-solid coupling, derived from Nitsche's method
