BUSCADOR RECOLECTA

The dataset is freely available on the web repository of the Spanish National Research Council (CSIC) in three different formats (NetCDF, binary raster, and plain text)., Format: netcdf The netcdf archive is composed of 96 zipped files containing the spei dataset from 1901 to 2006 at 1 to 48 months time scales, separated for the East hemisphere (i.e. Europa, Africa, Asia and Australia) and the West hemisphere (the Americas). Each zipped file contains one single netCDF file (.nc), i.e. no header files are necessary because all necessary meta-data are self-contained in the .nc file. Naming convention spei_[tempscale]_[hemisphere].zip, where [tempscale] is a number between 1 and 48 indicating the temporal scale of the index (months), and [hemisphere] indicates the fraction of the World covered and can have values eh (East hemisphere) or wh (West hemisphere). Example: spei_12_eh.zip, The Global 0.5° gridded SPEI dataset is made available under the Open Database License. Any rights in individual contents of the database are licensed under the Database Contents License. Users of the dataset are free to share, create and adapt under the conditions of attribution and share-alike. Use of the newest version is recommended. Older versions are still available to allow replicability., All currently available gridded drought datasets at continental and global scales are based on either the PDSI or the sc-PDSI. A new global drought dataset based on the Standardised Precipitation-Evapotranspiration Index (SPEI) has been developed, which covers time scales from 1-48 months at a spatial resolution of 0.5°, and provides temporal coverage for the period 1901-2006. This dataset represents an improvement in spatial resolution and operative capability of previous gridded drought datasets based on the PDSI, and enables identification of various drought types., A monthly global dataset of a multiscalar drought index is presented and compared in terms of spatial and temporal variability with the existing continental and global drought datasets based on the Palmer drought severity index (PDSI, scPDSI). The new dataset is based on the standardized precipitation evapotranspiration index (SPEI). The index was obtained from the CRU TS3.0 data, covering time scales from 1 to 48 months for the period 1901-2006, and has a spatial resolution of 0.5°. The advantages of the new dataset are that: i) it improves the spatial resolution of the unique global drought dataset at a global scale; ii) it is spatially and temporally comparable to other datasets, given the probabilistic nature of the SPEI, and, in particular; iii) it enables identification of various drought types, given the multiscalar character of the SPEI.

Each zipped file contains three files, one with the data itselt (.img), and two headers (.doc and .hdr). The information contained in the header files is equivalent, and allows direct access to the data using some widely used commercial programs. Naming convention: spei[tempscale]_[decade].zip, where [tempscale] is a number between 1 and 48 indicating the temporal scale of the index (months), and [decade] indicates the years of data contained in the file.

This corresponds to a series of approximately 40,000 quantum chemical calculations on one single system, the model dipeptide HCO-L-Ala-NH2, with 16 atoms and no charge. The conformational space of this molecule is scanned by defining a regular 12x12 grid from -165º to 165º in 30º steps in the 2D space spanned by its Ramachandran angles phi and psi. The energy at each of these 144-points set is calculated using using the methods RHF and MP2, and a large number of Pople basis sets ranging from 3-21G to 6-311++G(2df,2pd). These methods are combined using the same one for the geometry optimization and the energy calculation (homolevel) or different ones (heterolevel). The dataset contains 274 grids, each one corresponding to a different homo- or heterolevel. This consists of a set of human-readable ASCII files in the output format of Gaussian 03, in folders with descriptive names and compressed using tar and gzip (i.e., you need the GNU applications tar and gzip to uncompress them). Created with Gaussian 03, Revision C.02. Readable with any text editor. This dataset is made available under the Open Database License: http://opendatacommons.org/licenses/odbl/1.0/. Any rights in individual contents of the database are licensed under the Database Contents License: http://opendatacommons.org/licenses/dbcl/1.0/, This dataset is the basis of an exhaustive published study (see https://digital.csic.es/handle/10261/35334) of more than 250 ab initio potential energy surfaces (PESs) of the model dipeptide HCO-L-Ala-NH2. The model chemistries (MCs) investigated are constructed as homo- and heterolevels involving possibly different RHF and MP2 calculations for the geometry and the energy. The basis sets used belong to a sample of 39 representants from Pople's split-valence families, ranging from the small 3-21G to the large 6-311++G(2df,2pd). The reference PES to which the rest are compared is the MP2/6-311++G(2df,2pd) homolevel, which, as far as we are aware, wss the most accurate PES in the literature at the moment of its publication. The great number of MCs evaluated has allowed us to significantly explore this space and show that the correlation between accuracy and computational cost of the methods is imperfect, thus justifying a systematic search for the combination of features in a MC that is optimal to deal with peptides. Regarding the particular MCs studied, the most important conclusion is that the potentially very cost-saving heterolevel approximation is a very efficient one to describe the whole PES of HCO-L-Ala-NH2. Finally, we show that, although RHF may be used to calculate the geometry if a MP2 single-point energy calculation follows, pure RHF//RHF homolevels are not recommendable for this problem., This work has been supported by the research projects E24/3 and PM048 (Aragón Government), MEC (Spain) FIS2006-12781-C02-01 and MCyT (Spain) FIS2004-05073-C04-01.

De esta base de datos se han recogido revistas que cumpliesen los criterios de categorización (A o B) elaborados por el Grupo de Investigación EPUC, del CCHS del CSIC, y que fuesen de las siguientes materias: Antropología, Arqueología-Prehistoria, Bellas Artes, Biblioteconomía y Documentación, Ciencias Jurídicas, Economía, Ciencias de la Educación, Filosofía, Geografía, Historia, Lingüística, Literatura, Psicología, Ciencias Políticas, Sociología, Urbanismo, América Latina, Miscelánea. Se presentan datos acerca de la evolución temporal, revistas editoras, autoría de los artículos y filiación institucional de los autores. También se examina la producción de libros reseñados según tipo documental, idioma de edición, autoría, entidad editora, y la duración del intervalo de tiempo entre edición de libro y reseña. Los resultados permiten indicar un descenso constante durante el periodo indicado en la producción de reseñas, y un elevado porcentaje de documentos de humanidades. Los autores son en su mayoría profesores universitarios y españoles; publican solos; tienen una productividad muy baja; y un alto nivel de endogamia en aquellos que son miembros de Consejos de revista. Los resultados sobre libros reseñados demuestran que hay pocos títulos reseñados más de una vez, un elevado número de monografías, muchas en español, y un intervalo alto de tiempo entre la edición de los libros y su reseña., Esta base es resultado de un proyecto de investigación financiado por el CSIC., Peer reviewed

The item is made of 2 files, of which 1 is the dataset and the other include detailed information about measures realized.-- Dataset contributed to the Project Carbochange, This dataset gathers discrete measurements of CO2 (pH and alkalinity) and hydrographic variables (salinity, temperature, dissolved oxygen, nitrate, phosphate and silicate) obtained during the cruise MOC2EQ carried out from 5 April to 16 May 2010. pH was measured spectrophotometrically following the Clayton and Byrne (1993). This method consists on adding a dye solution to the seawater sample, so that the ratio between two absorbances at two different wavelengths is proportional to the sample pH. Alkalinity was measured using an automatic potentiometric titrator Titrando 809 Metrohm, with a Metrohm 6.0232.100 combination glass electrode and a Pt-1000 probe for temperature measurement following the methodology given by Pérez and Fraga (1987).
