One-year study of airborne sugar compounds: cross-interpretation with other chemical species and meteorological conditions

The daily evolution of seventeen sugar compounds (seven saccharides, seven alcohol-saccharides and three anhydrosaccharides) in atmospheric aerosol samples collected between 9 March 2016 and 14 March 2017 was studied in León (Spain). The main links between the concentration of sugar compounds and various chemical species, pollen, fungal spores and meteorological conditions were investigated. The results showed that, in spring, when high levels of metabolic activity of the plants occur and temperatures increase, glucose, sucrose, 2-methyl-erithritol, mannitol, arabitol and inositol, are significantly correlated with airborne pollen concentrations. Between spring and autumn, Alternaria air concentrations are significantly correlated with temperatures, arabitol and sorbitol + adonitol concentrations. Furthermore, during rainy days, Alternaria is also correlated with mannitol. In autumn, lower temperatures cause an increase in the concentrations of levoglucosan, mannosan and galactosan, probably due to the increased use of domestic heating devices. These anhydrosugars and arabinose, fructose and glucose, are significantly correlated with K, NO3−, EC, OC, Cu, Zn, Se, Pb, V and Ni, while mannosan also correlates with As, showing that these anhydrosaccharides can be emitted from different anthropogenic sources. Precipitation causes an increase in glucose and sucrose concentrations, due to the break of pollen particles that produce hundreds of fine size particles. Besides, precipitation causes an increase in arabitol concentrations, due to the release and growth of fungi.publishe

The European Solar Telescope

The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design combines the knowledge and expertise gathered by the European solar physics community during the construction and operation of state-of-the-art solar telescopes operating in visible and near-infrared wavelengths: the Swedish 1m Solar Telescope, the German Vacuum Tower Telescope and GREGOR, the French Télescope Héliographique pour l'Étude du Magnétisme et des Instabilités Solaires, and the Dutch Open Telescope. With its 4.2 m primary mirror and an open configuration, EST will become the most powerful European ground-based facility to study the Sun in the coming decades in the visible and near-infrared bands. EST uses the most innovative technological advances: the first adaptive secondary mirror ever used in a solar telescope, a complex multi-conjugate adaptive optics with deformable mirrors that form part of the optical design in a natural way, a polarimetrically compensated telescope design that eliminates the complex temporal variation and wavelength dependence of the telescope Mueller matrix, and an instrument suite containing several (etalon-based) tunable imaging spectropolarimeters and several integral field unit spectropolarimeters. This publication summarises some fundamental science questions that can be addressed with the telescope, together with a complete description of its major subsystems

Les entreprises multinationales et l'adaptation des pays producteurs traditionnels : le cas de Sogrape (Portugal)

International audienceLes auteurs analysent le cas du groupe vitivinicole portugais (Sogrape) dans le but d'expliquer les stratégies d'adaptation et de survie des firmes dans les pays producteurs traditionnels. Pour ce faire, ils élaborent une grille d'analyse pour cerner les forces qui influencent la structure de cette industrie. Par la suite, ils expliquent la façon dont Sogrape a bâti un avantage compétitif sur les marchés internationaux. Enfin, des suggestions portent sur la façon dont les firmes familiales vitivinicoles pourraient construire des avantages compétitifs dans l'industrie vitivinicole

[Cas de réussite dans les secteurs traditionnels de l'industrie portugaise]

International audienceLe chapitre porte sur l'étude de cas de réussite dans les secteurs traditionnels de l'économie portugaise. Au plan conceptuel, les auteurs proposent une grille de lecture qui articule les objectifs des firmes et leurs configurations organisationnelles. L'étude empirique est basée sur des interviewes qualitatives avec les dirigeants de deux PMEs portugaises, dans les industries de la chaussure (Marisport) et des appareils pour chauffage d'eau (Vulcano). Finalement, les implications de leurs résultats en ce qui concerne l'efficacité de ces organisations et la conduite des politiques économiques sont discutées

Determinantes de inovaço e desempenho economico-financeiro : ensaio para a industria transformadora Portuguesa

International audienceLes auteurs analysent l'impact de l'innovation sur la performance économique et financière des entreprises industrielles portugaises (1995-2001). En partant d'une première revue de la littérature ils élaborent des hypothèses mettant en relation ces deux concepts (innovation et performance). Les hypothèses sont testées à l'aide des modèles logit et probit et d'un système d'équations simultanées pour identifier les facteurs qui déterminent chaque phase du processus d'innovation et rechercher des interactions éventuelles entre les différentes phases. Les données sont issues de l'enquête Community innovation survey (CIS2), concernant le Portugal. Des informations supplémentaires relatives aux performances financières ont été recueillies pour la période 1995-2001 (Banque du Portugal). Les résultats montrent : (i) l'innovation a un impact positif sur les performances économiques et financières des entreprises industrielles portugaises ; (ii) il existe un effet de rétroaction entre les différentes phases du processus d'innovation (inputs, outputs et performance)

Report of a Working Group on Medicinal and Aromatic Plants: Fourth meeting, 29 September-1 October 2009, Kusadasi, Turkey

The Fourth Meeting of the ECPGR Working Group (WG) on Medicinal and Aromatic Plants (MAPs) was held on 29 September to 1 October 2009 in Kusadasi, Turkey, organized by the Aegean Agricultural Research Institute. The meeting was attended by 23 representatives from ECPGR member countries and 7 observers. Major items discussed include: crop-specific characterization and evaluation descriptors for the ten priority species selected by the WG; documentation of ex situ collections and in situ populations; implementation of “A European Genebank Integrated System” (AEGIS) (selection of accessions for the European Collection, adoption of AEGIS quality standards for conservation of accessions in ex situ genebanks). The meeting also focused on the project for “Conservation and characterization of oregano (Origanum vulgare L.) wild populations in Europe”. The revised project document was presented and endorsed. The list of project partners and detailed workplan are included in the present report. The University of Veterinary Medicine in Vienna will carry out molecular and chemical analyses. The data collected would contribute to the selection of oregano accessions to be included in a European Collection according to the AEGIS concept. The WG decided that the original “priority list” of MAP species should be expanded, to show the existence of some common regional strategies and priorities and support the choice of species by national projects. The ten target species will, however, remain as highest priority for the WG. The expanded priority list will be used to produce a document showing the level of threat and the Red List status for MAP species in Europe. Other opportunities for cooperation were identified: increase of the focus on in situ conservation; potential of in vitro or cryopreservation methods to improve the status of safety-duplication; usefulness of micropropagation methods for rare and threatened species, for conservation and reintroduction of species into former habitats, and for commercial production of plants and MAP products
