As reported in previous studies, Galicia (NW Spain) is an area of high radon concentrations. This study was sought to analyze the correlation between short-term (activated carbon) and long-term (alpha particle track) detectors in this geographic area, and ascertain whether there were differences in their readings that might be influenced by other variables.(More)
Radioactive emissions into the atmosphere from the damaged reactors of the Fukushima Dai-ichi nuclear power plant (NPP) started on March 12th, 2011. Among the various radionuclides released, iodine-131 ((131)I) and cesium isotopes ((137)Cs and (134)Cs) were transported across the Pacific toward the North American continent and reached Europe despite(More)
A parameter uncertainty analysis has been performed to derive the probability distribution of the weighted equivalent dose to lung for an adult (w(lung) H(lung)) per unit exposure to radon progeny in the home. The analysis was performed using the ICRP Publication 66 human respiratory tract model (HRTM) with tissue weighting factor for the lung, w(lung) =(More)
The first Spanish intercomparison exercise for continuous radon monitors was carried out with the participation of nine monitoring systems from eight laboratories. The exposures were carried out in the radon and thoron chambers at the Institute of Energy Techniques (INTE) of the Technical University of Catalonia (UPC), which is considered to be the Spanish(More)
An intercomparison exercise for passive integrating radon detectors has been carried out with the participation of 12 detection systems from 10 laboratories. The detection systems comprise three commonly used in radon integrating measurements, tracks, activated charcoal canisters and electrets. The exposures were carried out in the radon and thoron chambers(More)
The objective of this study was to determine pharmacokinetic differences of acetyl salicylic acid (ASA) and its metabolites: gentisic acid (GA), salicylic acid (SA) and salicyluric acid (SUA) between Otomies and Mesticians healthy subjects. Design. Ten Otomies and 10 Mesticians were included. After a single dose of aspirin given orally (15 mg/kg), blood and(More)
®) was established in 1975 to identify and analyze alternative national and international strategies and policies for meeting food needs of the developing world on a sustainable basis, with particular emphasis on low-income countries and on the poorer groups in those countries. While the research effort is geared to the precise objective of contributing to(More)
We explore a framework to model the dose response of allosteric multisite phosphorylation proteins using a single auxiliary variable. This reduction can closely replicate the steady state behavior of detailed multisite systems such as the Monod-Wyman-Changeux allosteric model or rule-based models. Optimal ultrasensitivity is obtained when the activation of(More)
The present article revises the major topics related to fish and coral reproduction. In particular after a short review of the ornamental trade and the destructive fishing methods that are still used in some areas, the present review revises the principal modes of fish and coral reproduction introducing the main critical bottlenecks in their captive(More)
For the first time, a comparison of radon activity concentration in air has been performed within the scope of Euromet. In the project 657, 'Comparison of calibration facilities for the radon activity concentration,' 12 participants from 9 countries compared different radon reference atmospheres at 1, 3 and 10 k Bq m-3 via a transfer standard. The(More)
