Consideraciones sobre la cláusula irph a la luz de sus antecedentes y de la doctrina consolidada del tribunal de justicia de la union europea
2021
By issuing its judgment of March 3, 2020, the Court of Justice of the European Union (CJEU) has terminated the last episode in the evolution of the IRPH index to which almost a tenth of mortgages have been referring. in Spain, compared to the rest that the Euribor takes as a reference, declaring in essence that consumers will be able to go to court to declare the abusiveness of the clause that the aforementioned index contains in the deeds of constitution of the mortgage. To understand the scope of the current situation, it is convenient to consider even briefly what the IRPH consists of and the consequences that its application has entailed for the affected consumer borrowers, taking into …
Deep-Sea Bioluminescence Blooms after Dense Water Formation at the Ocean Surface
2013
The deep ocean is the largest and least known ecosystem on Earth. It hosts numerous pelagic organisms, most of which are able to emit light. Here we present a unique data set consisting of a 2.5-year long record of light emission by deep-sea pelagic organisms, measured from December 2007 to June 2010 at the ANTARES underwater neutrino telescope in the deep NW Mediterranean Sea, jointly with synchronous hydrological records. This is the longest continuous time-series of deep-sea bioluminescence ever recorded. Our record reveals several weeks long, seasonal bioluminescence blooms with light intensity up to two orders of magnitude higher than background values, which correlate to changes in th…
Grounded theory for generating theory in the study of information behavior
2012
The use of grounded theory procedures for the study of information behavior has contributed to generating theory in this field. Thirty-one works were analyzed with regard to a) their relationship to the context in which the research was carried out, b) the aspect of information behavior researched, c) the use of grounded theory procedures, and d) the generation of theory. Most of the studies were carried out in the context of health information, and grounded theory procedures were for the most part only partially applied. The theoretical propositions produced depended on the subject being studied. Although this methodology is suitable for the study of an individual’s interaction with inform…
El problema de la descarga del agua subterránea al medio superficial: estudio de esquemas de conocimiento en universitarios
2010
En este trabajo se muestran los resultados de un estudio sobre los esquemas de conocimiento de estudiantes universitarios en relación a la importancia que prestan al agua subterránea para explicar el caudal de un río tras un tiempo sin precipitaciones, así como su integración en sus representaciones gráficas sobre el ciclo del agua. Los resultados indican una importante incultura hidrogeológica de los universitarios, reclamándose la toma de conciencia y formación del profesorado en general en este campo, así como la realización de campañas divulgativas para paliar los problemas que afectan a una adecuada gestión de los recursos hídricos subterráneos.
A theoretical study of the 1B2u and 1B1u vibronic bands in benzene
2000
The two lowest bands, 1B2u and 1B1u, of the electronic spectrum of the benzene molecule have been studied theoretically using a new method to compute vibronic excitation energies and intensities. The complete active space (CAS) self-contained field (SCF) method (with six active π-orbitals) was used to compute harmonic force field for the ground state and the 1B2u and 1B1u electronic states. A linear approximation has been used for the transition dipole as a function of the nuclear displacement coordinates. Derivatives of the transition dipole were computed using a variant of the CASSCF state interaction method. Multiconfigurational second-order perturbation theory (CASPT2) was used to obtai…

Search for Extraterrestrial Point Sources of Neutrinos with AMANDA-II
2003
We present the results of a search for point sources of high energy neutrinos in the northern hemisphere using AMANDA-II data collected in the year 2000. Included are flux limits on several AGN blazars, microquasars, magnetars and other candidate neutrino sources. A search for excesses above a random background of cosmic-ray-induced atmospheric neutrinos and misreconstructed downgoing cosmic-ray muons reveals no statistically significant neutrino point sources. We show that AMANDA-II has achieved the sensitivity required to probe known TeV gamma-ray sources such as the blazar Markarian 501 in its 1997 flaring state at a level where neutrino and gamma-ray fluxes are equal.
Musically induced ASMR : an amalgamated experience
2015
Musically induced ASMR is an Autonomous Sensory Meridian Response triggered by music. The term ASMR is best known on the internet by communities who report experiencing this phenomenon. It is most simply understood as an experience like musical chills, however can be triggered by nearly any form of stimuli. The current study employed grounded theory, a meticulous and established qualitative research method for developing theory that serves to explain salient characteristics of a particular phenomenon; to theorize the nature and significance of musically induced ASMR and ASMR in general. Based on the data collected, the study confirmed the existence of musically induced ASMR and demonstrates…
Asymptotic potentials and rate constants in the adiabatic capture centrifugal sudden approximation for X + OH(X-2 Pi) -> OX + H(S-2) reactions where …
2012
International audience; New long-range multipolar coefficients for the X + OH(X-2 Pi) interactions, where X = O(P-3), S(P-3) and N(S-4), are given here. They have been evaluated on the basis or monomer properties of the atoms and OH such as the dipole and quadrupole moments, and the static and dynamic polarizabilities. Each matrix element of the 18 x 18 (8 x 8 for N + OH) quasi-degenerate asymptotic potentials has been built up by means of the perturbation theory up to second order including or not the fine-structure of O, S and OH. The adiabatic potentials, obtained after diagonalization of the full matrix, show many crossings and complex behaviors near the asymptotes. Using the entrance c…
Acidochromism of the luminescence of bis(4-pyridylethenyl)arenes
2004
Abstract A series of C 2 -symmetrical bis[( E )-2-(4-pyridyl)ethenyl]arenes has been synthesised via two-fold PO-activated olefinations. 1,4-Benzene, 1,4-naphthalene, 9,10-anthracene and 2,2′-diphenyl were used as central units. These fluorescent compounds were freely soluble in common solvents. The absorption and the emission were sensitive towards solvent polarity and acid, in solution as well as in the solid state. Depending on the concentration of acid, protonation of the ground state and/or the excited state caused reductions of the fluorescence efficiencies, accompanied by bathochromic shifts of the absorption and the emission spectra of some chromophores. The title compounds, except …
