Estudio de las aguas de bebida minerales de las provincia de Valencia

Mediante la investigación de determinados parámetros, en las aguas de bebida minerales de la provincia de Valencia, buscamos la posible relación entre la composición de dichas aguas y las características geológicas de la zona. Del resultado de los análisis se deduce que las aguas menos mineralizadas se encuentran en los terrenos más antiguos del Buntsandstein de la zona Norte de la provincia, mientras que las más mineralizdadas las encontramos en terreno Keuper. La mayoría de las aguas minerales y de mesa se encuentran en terrenos triásicos o cretácicos. En las aguas de mesa que se explotan comercialmente predominan las bicarbonato-c4lcicas y bacteriológicamente suelen ser correctas si lo es la explotación. Del Mióceno y Cuaternario afloran aguas con sulfatos aumentados.With the investigation of determinates parameters in the mineral waters of the province of Valencia, we are looking for the possible relation between the composition of those water s and the geological characteristics of the zone.

Problemática de la presencia de detergentes en las aguas de consumo de la provincia de Valencia

Realizamos un muestreo de las aguas de consumo público de la provincia de Valencia investigando la presencia de detergentes en dichas aguas por el método del azul de metileno, y lo relacionamos con determinados factores ambientales. La presencia de detergentes en las aguas de consumo público se detectó principalmente en municipios de la zona costera, con abastecimientos situados en terrenos vulnerables por porosidad, con industrias cercanas y vertederos de residuos sólidos y líquidos situados también sobre terrenos vulnerables, también se detectó en municipios de las zonas interior e intermedia. Aunque no crea todavía una problemática grave deben vigilarse adecuadamente, sobre todo las zonas industrializadas.We made an investigation about the public consumption waters of the province of Valencia, investigating the presence of surfactif in those waters, intervening the method of the Mehylene Bleu Method, and we relate it with sorne environment factors. The presence of surfactif in the public consumption water s was detected principally at townships of the coste zone with providings situated at permeables terrenes with porosity, with factorys near there, and sewers of solid-liquid residues situated on permeables terrenes too. Also we detected it at townships of intermedium zones and interior zone

The ArDM experiment

The aim of the ArDM project is the development and operation of a one ton double-phase liquid argon detector for direct Dark Matter searches. The detector measures both the scintillation light and the ionization charge from ionizing radiation using two independent readout systems. This paper briefly describes the detector concept and presents preliminary results from the ArDM R&D program, including a 3 l prototype developed to test the charge readout system.Comment: Proceedings of the Epiphany 2010 Conference, to be published in Acta Physica Polonica

Measurement of the scintillation time spectra and pulse-shape discrimination of low-energy beta and nuclear recoils in liquid argon with DEAP-1

The DEAP-1 low-background liquid argon detector was used to measure scintillation pulse shapes of electron and nuclear recoil events and to demonstrate the feasibility of pulse-shape discrimination (PSD) down to an electron-equivalent energy of 20 keV. In the surface dataset using a triple-coincidence tag we found the fraction of beta events that are misidentified as nuclear recoils to be $<1.4\times 10^{-7}$ (90% C.L.) for energies between 43-86 keVee and for a nuclear recoil acceptance of at least 90%, with 4% systematic uncertainty on the absolute energy scale. The discrimination measurement on surface was limited by nuclear recoils induced by cosmic-ray generated neutrons. This was improved by moving the detector to the SNOLAB underground laboratory, where the reduced background rate allowed the same measurement with only a double-coincidence tag. The combined data set contains $1.23\times10^8$ events. One of those, in the underground data set, is in the nuclear-recoil region of interest. Taking into account the expected background of 0.48 events coming from random pileup, the resulting upper limit on the electronic recoil contamination is $<2.7\times10^{-8}$ (90% C.L.) between 44-89 keVee and for a nuclear recoil acceptance of at least 90%, with 6% systematic uncertainty on the absolute energy scale. We developed a general mathematical framework to describe PSD parameter distributions and used it to build an analytical model of the distributions observed in DEAP-1. Using this model, we project a misidentification fraction of approx. $10^{-10}$ for an electron-equivalent energy threshold of 15 keV for a detector with 8 PE/keVee light yield. This reduction enables a search for spin-independent scattering of WIMPs from 1000 kg of liquid argon with a WIMP-nucleon cross-section sensitivity of $10^{-46}$ cm$^2$, assuming negligible contribution from nuclear recoil backgrounds.Comment: Accepted for publication in Astroparticle Physic

First results on light readout from the 1-ton ArDM liquid argon detector for dark matter searches

ArDM-1t is the prototype for a next generation WIMP detector measuring both the scintillation light and the ionization charge from nuclear recoils in a 1-ton liquid argon target. The goal is to reach a minimum recoil energy of 30\,keVr to detect recoiling nuclei. In this paper we describe the experimental concept and present results on the light detection system, tested for the first time in ArDM on the surface at CERN. With a preliminary and incomplete set of PMTs, the light yield at zero electric field is found to be between 0.3-0.5 phe/keVee depending on the position within the detector volume, confirming our expectations based on smaller detector setups.Comment: 14 pages, 10 figures, v2 accepted for publication in JINS

Gitools: Analysis and Visualisation of Genomic Data Using Interactive Heat-Maps

Intuitive visualization of data and results is very important in genomics, especially when many conditions are to be analyzed and compared. Heat-maps have proven very useful for the representation of biological data. Here we present Gitools (http://www.gitools.org), an open-source tool to perform analyses and visualize data and results as interactive heat-maps. Gitools contains data import systems from several sources (i.e. IntOGen, Biomart, KEGG, Gene Ontology), which facilitate the integration of novel data with previous knowledge

Analysis of the melon (Cucumis melo) small RNAome by high-throughput pyrosequencing

Abstract Background Melon (Cucumis melo L.) is a commercially important fruit crop that is cultivated worldwide. The melon research community has recently benefited from the determination of a complete draft genome sequence and the development of associated genomic tools, which have allowed us to focus on small RNAs (sRNAs). These are short, non-coding RNAs 21-24 nucleotides in length with diverse physiological roles. In plants, they regulate gene expression and heterochromatin assembly, and control protection against virus infection. Much remains to be learned about the role of sRNAs in melon. Results We constructed 10 sRNA libraries from two stages of developing ovaries, fruits and photosynthetic cotyledons infected with viruses, and carried out high-throughput pyrosequencing. We catalogued and analysed the melon sRNAs, resulting in the identification of 26 known miRNA families (many conserved with other species), the prediction of 84 melon-specific miRNA candidates, the identification of trans-acting siRNAs, and the identification of chloroplast, mitochondrion and transposon-derived sRNAs. In silico analysis revealed more than 400 potential targets for the conserved and novel miRNAs. Conclusion We have discovered and analysed a large number of conserved and melon-specific sRNAs, including miRNAs and their potential target genes. This provides insight into the composition and function of the melon small RNAome, and paves the way towards an understanding of sRNA-mediated processes that regulate melon fruit development and melon-virus interactions.This work was supported by grants AGL2009-07552/AGR, BIO2006-13107 (Ministerio de Ciencia e Innovación, Spain) and MELONOMICS (Fundación Genoma España, Spain).Peer Reviewe
