It is a well known quandry that when countries open their financial sectors, foreign-owned banks appear to bring superior efficiency to their host markets but also charge higher markups on borrowed funds than their domestically owned rivals, with unknown impacts on interest rates and welfare. Using heterogeneous, imperfectly competitive lenders, the model(More)
15 Soil moisture variability and the depth of water stored in the arable layer of the soil are 16 important topics in agricultural research and rangeland management. In this study we use the 17 Distributed Rainfall-Runoff (DR2) model to perform a detailed mapping of topsoil moisture 18 status (SMS) in a mountain Mediterranean catchment. This model,(More)
Bursaphelenchus xylophilus, the pine wilt nematode (PWN), is a quarantine organism with a high potential to damage conifer forests in Europe. This has driven the European Union to protect forest stands from the propagation and dispersion of this pathogen. However, the current control measures have been unsuccessful in preventing the dispersion of this(More)
Cerussite, an orthorhombic lead carbonate mineral, has a structure and physical properties that cannot be understood merely in terms of ionic anion-cation interactions. The nature of the chemical bonding in cerussite is analyzed by means of the quantum theory of atoms in molecules (QTAIM) and the analysis of the electron localization function (ELF). A long(More)
The activation of the vanadium(V)-catalysed aerial oxidation of sodium 4,8-diamino-1,5 -dihydroxyanthraquinone-2,6-disulphonate by iron(III) is discussed. The oxidation product is intensely fluorescent and allows fluorescence-monitoring of the slow reaction, which is preceded by an induction period. On the basis of this investigation, an accurate method for(More)
Flow accumulation algorithms (FAAs) predict the cumulative upstream drainage but each FAA generates a different map and this uncertainty still remains unsolved. This study makes advances in flow path research by testing 8 FAAs and analyzing the uncertainties of 15 simulations. The DR2-2013 © SAGAv1.0 hydrological software is presented in a study carried out(More)
A kinetic method for determination of traces of vanadium(V) (0.04-0.5 ppm) is described. It is based on the catalytic action of vanadate in the autoxidation of sodium 4,8-diamino-1,5-dihydroxyanthraquinone-2,6-disulphonate, giving rise to kinetic curves characterized by an induction period before the appearance of a product exhibiting an intense red(More)
Three kinetic methods for the determination of manganese, two of them by photometric monitoring and another by fluorimetric monitoring, based on the oxidation of sodium 4,8-diamino-1,5-dihydroxyanthraquinone-2,6-disulphonate are described. A critical comparative evaluation of both monitoring techniques and their effect on the analytical figures of merit of(More)
A sensitive fluorimetric method for the determination of zinc, based on the formation of a fluorescent chelate with benzyl 2-pyridyl ketone 2-pyridylhydrazone is described. In darkness, the fluorescence develops rapidly and remains stable for 1 hr. The detection limit is 15 ng/ml. The effect of reaction variables, and methods of removing interferences, are(More)
A homogeneous immunofluorimetric technique to determine dichlorprop herbicide is described. Simultaneous determinations of both free and antibody-bound fluoresceinamine-labeled dichlorprop were carried out by measuring phase-resolved fluorescence or modulation-resolved fluorescence. The difference between the recorded values of the fluorescence lifetimes of(More)
