L’erotisme a les Cartes a les Senyores dels Àngels i de Jerusalem, de Francesc Fontanella
2014
Resum: Aquest article se centra en l'estudi del tractament de l'erotisme en algunes de les composicions pòetiques de Francesc Fontanella (1622-1682/3). El treball estudia quinze epístoles literàries que l'autor va dedicar a les monges dels convents dels Àngels i de Jerusalem de Barcelona durant la dècada de 1640. Es divideix en dues parts; a la primera s'identifiquen les composicions objecte d'estudi, es presenten breument i s'aclareixen alguns problemes relacionats amb la seva transmissió. A la segona s'analitzen detalladament totes les referències eròtiques presents als textos. Aquesta anàlisi, d'una banda, permet presentar una interpretació del sentit argumental del conjunt epistolar. D…
FRACTALITY EVIDENCE AND LONG-RANGE DEPENDENCE ON CAPITAL MARKETS: A HURST EXPONENT EVALUATION
2014
Since the existence of market memory could implicate the rejection of the efficient market hypothesis, the aim of this paper is to find any evidence that selected emergent capital markets (eight European and BRIC markets, namely Hungary, Romania, Estonia, Czech Republic, Brazil, Russia, India and China) evince long-range dependence or the random walk hypothesis. In this paper, the Hurst exponent as calculated by R/S fractal analysis and Detrended Fluctuation Analysis is our measure of long-range dependence in the series. The results reinforce our previous findings and suggest that if stock returns present long-range dependence, the random walk hypothesis is not valid anymore and neither is…
Ordination analysis and bioindices based on zoobenthos communities used to assess pollution of a lake in southern Finland
1990
The suitability of an ordination method, detrended correspondence analysis (DCA), was tested in assessing the degree of pollution of a large lake on the basis of the zoobenthos communities. Lake Etela-Saimaa, in southern Finland, was originally oligotrophic but is now heavily loaded by effluents from the wood-processing industry. Comparison between areas was complicated by variation in the water depths of the lake sub-basins. A horizontal pollution gradient could, however, easily be detected by means of the DCA in both the profundal and sublittoral zones. The benthic quality index (BQI) based on the composition of the profundal chironomid fauna failed at some stations because the indicator …
Pompei all'opera: iconografie romane nella Jone di Errico Petrella
2019
All'interno degli studi dedicati alla storia della tradizione classica, non tutti i possibili campi di ricerca sono stati completamente esplorati. Un argomento scarsamente messo in evidenza è lo scenario delle opere che mettono in scena il mondo greco-romano. Tra le opere di ambientazione classica composte nel corso del XIX secolo, uno dei maggiori successi, anche se oggi quasi dimenticato, fu Jone di Errico Petrella (1813-1877). Il libretto di quest'opera (eseguita per la prima volta a Milano, al Teatro alla Scala, nel 1858) era stato tratto dal celebre romanzo The Last Days of Pompeii di Edward Bulwer-Lytton (1834). Within the studies dedicated to the history of the classical tradition, n…
El teletreball pot resoldre el problema de la conciliació laboral, personal i familiar?
2020
La crisis sanitària de la COVID-19, amb els seus efectes sobre l'economia, ha donat lloc a una accelerada implantació del teletreball com a modalitat de treball preferent. Aquesta forma de treball no presencial, gràcies a les xarxes virtuals, s'ha defensat al llarg dels anys com un mecanisme ideal per a la solució de l'anomenat problema de conciliació entre la vida laboral, personal i familiar, donada la flexibilitat en l'ús del temps que ofereix. Al llarg d'aquest article, però, s'argumenta que el teletreball no és la resposta al repte de la conciliació. A partir del paradigma del policy approach, s'analitza com les conegudes polítiques de conciliació es formulen des de l'administració púb…
Evaluation of changes in ion release and biological properties of NeoMTA‐Plus and Endocem‐MTA exposed to an acidic environment
2018
AIM To analyse in vitro changes in ion release and biological properties of Endocem-MTA (Maruchi, Wonju, Korea) and NeoMTA-Plus (Avalon Biomed Inc, Bradenton, FL, USA) exposed to acidic or neutral environment on human dental periodontal ligament stem cells (hPDLSCs). METHODOLOGY Cell viability and wound healing assays were performed using eluates of each material. Cell death and changes in phenotype induced by the set endodontic sealer eluates were evaluated through flow cytometry. To evaluate cell attachment to the different materials, hPDLSCs were directly seeded onto the material surfaces and analysed by scanning electron microscopy. The chemical composition of the materials was determin…

Experimental Investigation for Local Tank Inflow Model
2014
In the present paper the effect of private roof tanks and of the float valve characteristics on apparent losses due to water meter errors was investigated via an experimental study. The tests were carried out at the Environmental Hydraulic Laboratory of the University of Enna (Italy), on a high-density polyethylene (HDPE 100 PN16) looped distribution network. The experimental results showed that network pressure plays an important role in the characterisation of the floating ball valve emitter law, but the tank operating condition is the most relevant aspect to be considered mainly for water meter error evaluation.

Carbon’s Three-Center-Four-Electron Tetrel Bond, Treated Experimentally
2018
Tetrel bonding is the noncovalent interaction of group IV elements with electron donors. It is a weak, directional interaction that resembles hydrogen and halogen bonding yet remains barely explored. Herein, we present an experimental investigation of the carbon-centered, three-center, four-electron tetrel bond, [N−C− N]+ , formed by capturing a carbenium ion with a bidentate Lewis base. NMRspectroscopic, titration-calorimetric, and reaction-kinetic evidence for the existence and structure of this species is reported. The studied interaction is by far the strongest tetrel bond reported so far and is discussed in comparison with the analogous halogen bond. The necessity of the involvement of…
