Traditional methods of plane grilled modeling used for the calculation of prestressed hollow core slab bridge decks not provide sufficient accuracy to determine the influence of phenomena such as slabs torsion or shear between the interface slab-toping. A new hybrid modeling approach is proposed. It allows more realistically quantify the resistant mechanism of this type of decks. The application of the method on a typical deck has yielded results that show the good correlation between the numerical predictions and the behavior observed in reality. Los métodos tradicionales de emparrillado plano utilizados para el cálculo de tableros conformados con placa alveolar pretensada no aportan suficiente precisión para determinar la influencia de fenómenos tales como la torsión sobre las placas o el rasante entre la capa de reparto y la propia placa. Se propone un nuevo método de modelización híbrido que permite cuantificar de forma más realista el mecanismo resistente de este tipo de tableros. La aplicación del método sobre un tablero tipo ha permitido obtener unos resultados que demuestran la buena correlación de las predicciones numéricas con el comportamiento observado en la realidad.

Three autochthonous grapevine varieties of Majorca (Spain) were analyzed for the presence of viruses listed by the international certification programs. Enzyme-Linked Immuno-Sorbent Assay (ELISA) screenings were performed in 193 vines from 46 vineyards included in a clonal selection. Virus-free vines were only 6.4%, 9.6% and 11.5%, in Manto Negro, Callet and Moll, respectively. Infections by grapevine leafroll associated viruses (GLRaVs) were ascertained in 71%, 78% and 60% of Manto Negro, Callet and Moll vines, respectively. Each variety was also highly infected by Grapevine fanleaf virus (GFLV) and Grapevine fleck virus (GFkV). The percentage of plants displaying multiple infections was 58.4% in Manto Negro, 63.8% in Callet and 42.6% in Moll. Thus, it was very difficult to find virus-free clones with suitable agronomic characteristics to be considered as a reference for the grape market. In order to obtain certified propagation material under such conditions of endemic viral infection, sanitation should be the main focus in clonal selection processes. However, the time and financial requirements for proper sanitation process bring to consideration the need to use, at least temporarily, standard multiplication material while certified clones are achieved., En este estudio se analizó la presencia de las virosis contempladas por las leyes internacionales en tema de certificación en tres variedades de vid autóctonas de Mallorca. Para ello se realizó el test ELISA (enzyme-linked immuno-sorbent assay) sobre 193 cepas procedentes de 46 viñedos incluidos en un programa de selección clonal. Las cepas que resultaron libres de los virus analizados fueron el 6,4% en Manto Negro, el 9,6% en Callet y el 11,5% en Moll. Los porcentajes de cepas infectadas por los virus asociados al síndrome del enrollado de la vid (GLRaVs) fueron 71% en Manto Negro, 78% en Callet y 60% en Moll. Se detectaron también altas tasas de infecciones para el virus del entrenudo corto infeccioso de la vid (GFLV) y el virus del jaspeado de la vid (GFkV) en las tres variedades. Los porcentajes de cepas sujetas a infecciones múltiples fueron 58,4% en Manto Negro, 63,8% en Callet y 42,6% en Moll. Por tanto fue difícil encontrar cepas que cumpliesen tanto los requisitos sanitarios para la certificación como aquellos agronómicos necesarios según las exigencias del mercado vitivinícola. En tales condiciones de infecciones víricas endémicas, el saneamiento debería ser el primer objetivo a seguir con el fin de obtener material de propagación certificado. Sin embargo, el tiempo y los recursos económicos necesarios para llevar a cabo el proceso de saneamiento conllevan la necesidad de considerar el uso temporal de material de propagación estándar hasta que se obtengan clones certificados.

The increase in winter related health pediatric demand is associated with three factors: cold and rainy weather, air pollution and respiratory viral epidemics. During the winter of 2002 there was, successively, heavy rain, air pollution, cold weather and a respiratory syncytial virus (RSV) epidemic in Santiago. Aim: To study the influence of environmental factors and RSV epidemic on pediatric health care demand. Patients and methods: The number of hospital admissions and outpatient consultations for acute lower respiratory infections (ALRI) from April to October 2002 (Autumn to Spring in Chile), were registered in a public pediatric hospital of Santiago. A respiratory virus surveillance (RSV, adenovirus influenza and parainfluenza virus) was carried out among children admitted for ALRI. Climate conditions and air pollution (number of particles of more than 10 microns/mm3) values were provided by local environmental health services. Results: As expected, a rise in winter hospital admissions and outpatient consultations was detected, that peaked in week 29. This rise coincided with the higher RSV detection week. There was heavy rain in weeks 22, 23 and 30, as well as cold weather in June-July (weeks 23, 24, 26, 27 and 30; mid Winter), that did not increase health care demand. Likewise, high air pollution, registered from weeks 24 to 26, did not increase health care demand. Conclusions: RSV epidemic is the principal factor associated to the increase in health burden during winter in Santiago (Rev Méd Chile 2003; 131: 902-8)

We present a study of the intensity variations of the joint Fourier spectrum when one of two input objects is rotated while the other remains fixed by determining the average contrast as a function of the angle of rotation. The visibility behavior is explained in a theoretical and experimental way for simple test objects whose fine analog rotations are acquired with an optomechanical system that uses a high precision rotatory stage.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.
