Interrelación de laboratorios de control y laboratorios de investigación en España para la armonización de metodologías de determinación de toxinas paralizantes

XII Congreso Nacional de Agricultura, Madrid 24-26 de noviembre de 2009Marketing of cultured and harvested shellfish is linked to monitoring programs for granting food safety. Its complexity requires constant cooperation between research and monitoring laboratories in order to improve sampling and analysing performances, achieve legal requirements, etc. for increasing consumer’s health protection but not reducing producer’s benefits. The JACUMAR project «Comparison of methodologies for the evaluation of Paralytic Shellfish Poisoning (PSP) toxins in bivalves. Application for aquaculture in Spain» groups research and monitoring laboratories from Galicia, Andalucía and Cataluña. Efforts are focused on detection and quantification of PSP toxins, searching an analytical method able to fulfil technical and management requirementsEste proyecto está financiado por la Junta Asesora de Cultivos Marinos (JACUMAR), y los programas de control por los gobiernos autónomos de Galicia, Andalucía y CataluñaN

The GEOTRACES Intermediate Data Product 2014

The GEOTRACES Intermediate Data Product 2014 (IDP2014) is the first publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2013. It consists of two parts: (1) a compilation of digital data for more than 200 trace elements and isotopes (TEIs) as well as classical hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing a strongly inter-linked on-line atlas including more than 300 section plots and 90 animated 3D scenes. The IDP2014 covers the Atlantic, Arctic, and Indian oceans, exhibiting highest data density in the Atlantic. The TEI data in the IDP2014 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at cross-over stations. The digital data are provided in several formats, including ASCII spreadsheet, Excel spreadsheet, netCDF, and Ocean Data View collection. In addition to the actual data values the IDP2014 also contains data quality flags and 1-? data error values where available. Quality flags and error values are useful for data filtering. Metadata about data originators, analytical methods and original publications related to the data are linked to the data in an easily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2014 data providing section plots and a new kind of animated 3D scenes. The basin-wide 3D scenes allow for viewing of data from many cruises at the same time, thereby providing quick overviews of large-scale tracer distributions. In addition, the 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of observed tracer plumes, as well as for making inferences about controlling processes

Outage probability analysis for MRC in η-μ fading channels with co-channel interference

Exact closed-form expressions are obtained for the outage probability of maximal ratio combining in η-μ fading/nchannels with antenna correlation and co-channel interference. The scenario considered in this work assumes the joint presence of background white Gaussian noise and independent Rayleigh-faded interferers with arbitrary powers. Outage probability results are obtained through an appropriate generalization of the moment-generating function of the/nη-μ fading distribution, for which new closed-form expressions are provided.The work of D. Morales and A. Lozano is supported by AGAUR (2009/nSGR 70) and by the Spanish Ministry of Science and Innovation (Ref. CONSOLIDER-INGENIO CSD2008-00010 ”COMONSENS”). The work of J. F. Paris was supported in part by the Spanish Government and FEDER project TEC2011-25473
