Conceptions of happiness and its relationship with subjective well-being: A study through Natural Semantic Networks
2018
La búsqueda de la felicidad es uno de los fines más ansiados por los seres humanos. Así mismo, cada vez son más los estudios dentro de la psicología que buscan hallar cuáles son los factores involucrados en la felicidad. Existen dos grandes enfoques para su estudio, el paradigma hedonista y el paradigma eudaimónico. El paradigma hedónico propone que el bienestar depende principalmente de vivir una vida con experiencias placenteras; mientras que el paradigma eudaimónico refiere que el bienestar no solo se logra mediante el placer, sino principalmente a través de la actualización del potencial humano. En el presente estudio se trabajó con una muestra compuesta por 340 ciudadanos de Córdoba (A…

Biotic recovery after the end-Triassic extinction event: Evidence from marine bivalves of the Neuquén Basin, Argentina
2017
We analyze the Late Triassic extinction and Early Jurassic recovery of bivalve faunas within marine environments in the Atuel River area of the Neuquén Basin, Argentina. Data were collected from a hundred samples with invertebrates in a well-exposed uppermost Triassic to lower Jurassic section in the Neuquén Basin (southern Mendoza Province, Argentina) and allow a high-resolution reconstruction of the local diversity dynamics. The nearly continuous presence of marine stenohaline major taxa such as cnidarians, rhynchonelliform brachiopods, echinoderms and cephalopods indicates normal salinity throughout. All bivalve species were identified, and each occurrence was recorded in meters above th…

DNA Oxidation Photoinduced by Norharmane Rhenium(I) Polypyridyl Complexes: Effect of the Bidentate N,N′-Ligands on the Damage Profile
2018
Re(I)--polypyridyl complexes have interesting and distinctive photochemical and photosensitizing properties. This work describes the capability to induce (or photoinduce) DNA damage of three Re(I)-complexes with a naturally occurring alkaloid called norharmane (nHo) as ligand: [Re(CO)₃ (nHo)(L)]CF₃ SO₃ where L=2,2'-bipyridine (ReBpy), phenanthroline (RePhen) or dipyrido[3,2-a:2',3'-c]phenazine (ReDppz). The interaction of the complexes with DNA was investigated by steady-state and time-resolved spectroscopy. Data show that the mode and strength of interaction depend on the chemical structure of the bidentate ligand. The complexes show a major static contribution to the overall interaction, …
5,5′-Bis-vanillin derivatives as discriminating sensors for trivalent cations
2015
[EN] Several bis-vanillin derivatives containing semicarbazone moieties have been prepared and used in discriminating trivalent cations. The prepared probes are readily obtained and they are usually highly crystalline. Depending on the ligand and the studied cations, quenching, enhancement or no changes in the fluorescence spectrum were observed. Using a series of the prepared ligands allows distinguishing between Fe3+, Cr3+ and Al3+. Detection limits and selectivity in front of divalent cations have been evaluated. (C) 2015 Elsevier Ltd.

Analisi degli approcci scientifici per la definizione comune di rinnovazione naturale con particolare riferimento all'ambiente mediterraneo
2015
La rinnovazione forestale è il futuro di ogni foresta ed è legata a diversi fenomeni ecologici. Molti studi hanno utilizzato vari metodi per analizzare la rinnovazione forestale; tuttavia, a livello internazionale, non esiste un metodo comune condiviso per classificare il fenomeno della rigenerazione stessa. Con l’obiettivo di trovare una possibile sintesi comune questo lavoro analizza il fenomeno della rinnovazione naturale attraverso sia l’analisi di inventari forestali sia di pubblicazioni scientifiche. La ricerca ha permesso di elaborare un elenco bibliografico multilingue attraverso l’interrogazione di database on-line, la ricerca con parole chiave e l’analisi dei riferimenti bibliogra…
