A simple stochastic model of point source solute transport in rivers based on gauging station data with implications for sampling requirements
No full textA simple point-source water quality model was constructed to explore hypothetical scenarios of linear alkylbenzene sulphonate (LAS) load variability, chemical degradation kinetics, river discharge and river velocities within the context of planned water quality monitoring in the river Lambro, northern Italy. LAS is an anionic surfactant and a commonly used ingredient of household detergents. Input loads were derived from flow and concentration measurements at sewage treatment works (STW). River travel times are approximated using hydraulic geometry concepts based on existing records of stage, discharge and velocity measurements. The model proved to be especially useful in predicting the impact of overflows from an undersized STW near the top of the catchment on diurnal variations in water quality downstream. Probability density functions (pdf's) of LAS concentrations for a number of points on the river were approximated by running the model stochastically (using a Monte Carlo procedure) over independent frequency distributions of discharge, temperature and input load. The predicted concentration pdf's were then used to estimate the number of random grab and 24h composite samples, which would be required in order to estimate mean concentrations with confidence. This is especially important in situations where the analysis is expensive and the sample budget is limited. The model results showed that grab sampling was not a viable strategy in the Lambro largely due to the very strong diurnal variability in concentrations induced by the STW overflow. This conclusion was corroborated by field data. Copyright (C) 1999 Elsevier Science Ltd

No full textWe present ALMA 230 GHz continuum and CO(2-1) observations of the nearby Compton-thick Seyfert galaxy ESO428-G14, with angular resolution 0.'' 7 (78 pc). CO(2-1) is distributed in clumpy spiral arms, a lopsided circumnuclear ring (CNR) with similar to 200 pc radius, and a transverse gas lane with size <100 pc, which crosses the nucleus and connects the two portions of the CNR. The main CO velocity gradient is consistent with a rotating disk with dynamical mass M-dyn = 5 x 10(9) M-circle dot within similar to 1 kpc. We detect off-plane gas motions with respect to the main disk plane which likely trace a molecular outflow with rate (M)over bar(of) approximate to 0.1-0.3 M-circle dot yr(-1), along a biconical structure with radius 700 pc. The CO outflow smoothly joins the warm molecular outflow detected in SINFONI/Very Large Telescope data in the central 170 pc, suggesting that the outflow may cool with increasing distance. Our dynamical modeling of the inner 100 pc region suggests a warped disk or bar, and of fast gas streams which may trace an inflow toward the AGN. The inner warped disk overlaps with the most obscured, CT region seen in X-rays. There, we derive a column density N (H-2) approximate to 2 x 10(23) cm(-2), suggesting that molecular gas may contribute significantly to the AGN obscuration. Most of the hard X-ray emitting nuclear region is deprived of cold molecular gas and shows a CO-cavity. The CO-cavity is filled with warm molecular gas traced by H-2, confirming that the 3-6 keV continuum and Fe K alpha emission are due to scattering from dense ISM clouds
I testi profetici tra latino e volgare
No full textIl contributo prende in esame la produzione profetica circolante sia in volgare che in latino nella Toscana tardo medievale. L’autore si concentra in particolare su tre dossier, e sui loro problemi peculiari: il corpus merliniano e il volgarizzamento ‘attivo’ realizzato da Paolino Pieri nella Storia di Merlino; la tradizione dissidente francescana dei fraticelli, sospesa tra fuga dal mondo, ripiegamento interiore e proselitismo (non privo di rischi) presso i laici; e infine l’ampia fortuna autentica e apocrifa, in prosa e in versi, di santa Brigida di Svezia – presto trasformata, in Toscana, da visionaria riformatrice in generica autorità profetico-politica.The essay discusses both vernacular and Latin prophetic texts circulating in late medieval Tuscany. The main focus lies on three case studies: the Merlin Corpus and the composite volgarizzamento elaborated by Paolino Pieri in the Storia di Merlino; the dissident tradition of the Franciscan fraticelli, torn between seclusion from the world, inner withdrawal, and proselytism; finally, the prose and verse writings attributed to Saint Birgitta of Sweden, quickly transformed in Tuscany from a visionary reformer into a broader prophetic authority
