Variación estacional y diaria del polen de Olea Europaea L. en la atmósfera de Córdoba en relación con los parámetros meteorológicos

Se hu realizado un estudio de la variación estacional de los granos de polen de Olea europaea L en la atmósfera de la ciudad de Córdoba durante los años 1982 y 1983. Para la recogida de las muestras se ha utilizado el Burkard spore·trap. El polen de esta especie puede ser uno de los agc11tes más impo1tantes en CJ.11.mto <~ la producción de polinosis primaveral en nuestra ciudad, alcanzándose las máximas concentraciones durante el mes de mayo y primera quincena de junio. Se han analizado los diferentes parámetros meteorológicos (precipitación, humedad temperatura y dirección del \'icnto}. Aparentemente la precipitación y la temperatura son los que ejercen una mayor influencia en la concentración de estos pólenes en la atmósfera de Córdoba. Se ha estudiado también la variación a lo larga del dfa de la conccotraci6n de polen, en ambos años las grá~cas son casi coincide ntes, detectándose la m<.~)'Or incide nci:.~ de granos hucia las Uos o trt!S de la tan..! t.We carricd oul a study on rhc annual variarion or pollcn from Olea r.umpaea L. in ibc atmosphcrc of the city ol Córdoba along 1932 and 1983.

Dynamical Boson Stars

The idea of stable, localized bundles of energy has strong appeal as a model for particles. In the 1950s John Wheeler envisioned such bundles as smooth configurations of electromagnetic energy that he called {\em geons}, but none were found. Instead, particle-like solutions were found in the late 1960s with the addition of a scalar field, and these were given the name {\em boson stars}. Since then, boson stars find use in a wide variety of models as sources of dark matter, as black hole mimickers, in simple models of binary systems, and as a tool in finding black holes in higher dimensions with only a single killing vector. We discuss important varieties of boson stars, their dynamic properties, and some of their uses, concentrating on recent efforts.Comment: 79 pages, 25 figures, invited review for Living Reviews in Relativity; major revision in 201

Protection of Spanish Ibex (Capra pyrenaica) against Bluetongue Virus Serotypes 1 and 8 in a Subclinical Experimental Infection

Many wild ruminants such as Spanish ibex (Capra pyrenaica) are susceptible to Bluetongue virus (BTV) infection, which causes disease mainly in domestic sheep and cattle. Outbreaks involving either BTV serotypes 1 (BTV-1) and 8 (BTV-8) are currently challenging Europe. Inclusion of wildlife vaccination among BTV control measures should be considered in certain species. In the present study, four out of fifteen seronegative Spanish ibexes were immunized with a single dose of inactivated vaccine against BTV-1, four against BTV-8 and seven ibexes were non vaccinated controls. Seven ibexes (four vaccinated and three controls) were inoculated with each BTV serotype. Antibody and IFN-gamma responses were evaluated until 28 days after inoculation (dpi). The vaccinated ibexes showed significant (P<0.05) neutralizing antibody levels after vaccination compared to non vaccinated ibexes. The non vaccinated ibexes remained seronegative until challenge and showed neutralizing antibodies from 7 dpi. BTV RNA was detected in the blood of non vaccinated ibexes from 2 to the end of the study (28 dpi) and in target tissue samples obtained at necropsy (8 and 28 dpi). BTV-1 was successfully isolated on cell culture from blood and target tissues of non vaccinated ibexes. Clinical signs were unapparent and no gross lesions were found at necropsy. Our results show for the first time that Spanish ibex is susceptible and asymptomatic to BTV infection and also that a single dose of vaccine prevents viraemia against BTV-1 and BTV-8 replication
