An Accurate Quartic Force Field and Fundamental Frequencies for the Ozonide Anion: A Rare Positive Anharmonicity for the Antisymmetric Stretch

2003

The CCSD(T) method has been used to compute a highly accurate quartic force field and fundamental frequencies for all 16O and 18O isotopomers of the ozonide anion. The CCSD and CASPT2 methods have also been used to verify the reliability of the CCSD(T) fundamental frequencies. The computed fundamental frequencies are in agreement with gas-phase experiments, but disagree with matrix isolation experiments for the antisymmetric stretch, ν3. CASPT2 calculations show that the antisymmetric part of the O3- potential surface is sensitive to the external environment. It is concluded that the antisymmetric stretch exhibits a significant matrix shift in the matrix isolation experiments and that the m…

Mechanism of redox transformation of titanocene dichloride centers immobilized inside a polypyrrole matrix—EQCM and XPS evidences

2005

Abstract We report electrochemical quartz crystal microbalance (EQCM) results for electrodeposition of titanocene derivatized polypyrrole p(Tc3Py) films and redox transformation of polypyrrole matrix and titanocene centers immobilized in the film. Films of p(Tc3Py), Tc3Py = Tc(CH 2 ) 3 NC 4 H 4 (Tc = Cl 2 TiCpCp′, Cp = C 5 H 5 , Cp′ = C 5 H 4 ) were obtained from acetonitrile solutions of monomer on a Pt disc or thin Au layer evaporated on 10 MHz quartz crystals. Polymerization efficiency, derived from the slope of the change of resonant frequency as a function of the deposition charge ranged from 54% to 75%. A gradual loss of redox activity of Tc centers during consecutive redox cycles of …

Une palette intentionnelle et significative : le symbolisme des couleurs dans quelques romans zoliens

2018

In naturalist novels, aiming to depict the reality as faithfully as possible, colours are particularly important, and need to be carefully selected. An attentive reader of Zola’s Rougon-Macquart series might notice a very special use of colours that are often charged with an important symbolic value: being not only an ornament or a detail, they frequently influence and/or express the characters’ features. The proposed classification shows some most relevant examples of Zola’s conception of colours in selected parts of the series.

Tra formale e informale: “Urban commons” per un nuovo progetto di spazio pubblico e un senso condiviso di cultura collettiva urbana

2013

Le dinamiche di contrazione e di crisi strutturale in corso in gran parte delle città europee richiedono di ripensare lo spazio urbano attraverso un diverso modello di sviluppo e un profondo cambiamento nel paradigma della pianificazione e del progetto. Allo stesso tempo, la rottura del patto di finanza pubblica generato dalla crisi rende strutturale la drastica riduzione degli investimenti e la capacità del welfare pubblico. Il tema della gestione locale degli “urban commons” sviluppato in ambito internazionale attraverso l’osservazione di esperienze di recupero e pratiche di “cura” di spazi in disuso che alimentano il senso di comunità dei cittadini propone nuove forme del progetto che in…

An Evaluation of the Belief in Science Scale

2019

The Belief in Science Scale (BISS) is a unidimensional measure that assesses the degree to which science is valued as a source of superior knowledge. Due to increased academic interest in the concept of belief in science, the BISS has emerged as an important measurement instrument. Noting an absence of validation evidence, the present paper, via two studies, evaluated the scale’s factorial structure. Both studies drew on data collected from previous research. Study 1 (N = 686), using parallel analysis and exploratory factor analysis, identified a unidimensional solution accounting for 56.43% of the observed variance. Study 2 (N = 535), using an independent sample, tested the unidimensional …

Crowdfunding civico: finanziamento collettivo come strategia di innovazione sociale

2013

Le città italiane da qualche anno stanno attraversando un momento difficile non solo in termini economici ma anche sociali e culturali in senso ampio. Tuttavia la crisi è anche un'opportunità di sperimentare strategie alternative e nuove forme di finanziamento collettivo, come il crowdfunding. Si tratta di un meccanismo che permette di finanziare collettivamente una proposta progettuale di vario genere, che in questo caso potrebbe essere legata alla città e agli spazi della vita sociale, per rafforzare il senso di appartenenza ed identità al luogo in cui i cittadini vivono e contribuire alla realizzazione di interventi per la riqualificazione urbana.

Importancia del Trabajo Social como forma de intervención municipal

2011

Trascurridos 30 años de la puesta en marcha del Sistema Público de Servicios Sociales, procede destacar el protagonismo desarrollado por los ayuntamientos que han sido el referente más significativo de la implantación del Sistema por su compromiso institucional en el desarrollo de los Servicios Sociales Generales Básicos, potenciando las Unidades de Trabajo Social en todos los municipios, lo que ha hecho visible para la ciudadanía, tanto las potencialidades de los Servicios Sociales, como sus déficits. Hoy se puede afirmar que las/los ciudadanas/os reclaman de los Servicios Sociales el mismo enfoque que perciben la Sanidad o la Educación, como pilares del Estado de Bienestar y se exige que …

Quartiere

2018

La parola quartiere apparentemente non ha bisogno di definizioni. Tutti sappiamo cos'è un quartiere e utilizziamo il termine quotidianamente. Eppure, se ci si sofferma a domandarsi cosa sia veramente un quartiere, o se i quartieri delle nostre città funzionano tutti allo stesso modo, allora affiorano diverse perplessità e forse la domanda più seria potrebbe essere questa: ha ancora senso parlare di quartieri, in una società liquida e virtuale come la nostra? Il quartiere non è forse il retaggio di un bel tempo andato, in cui si conoscevano davvero i propri vicini di casa ed era più facile scambiare due chiacchiere con il panettiere di fiducia piuttosto che chattare via Skype con un collega …

Historical building dating: refinement of established sample preparation protocol

2010

Abstract: The application of thermal (TL) and optical (OSL) stimulated luminescence on pottery and building materials has allowed to resolve numer-ous problems in both the fields of retrospective do-simetry and dating. Routine measurements request the registration of TL signals obtained on polymineral fine-grained frac-tion (FG) extracted from pottery sherds and bricks used as building material with the Added Dose (AD) technique. One of the reasons of the dispersion of the lumi-nescence measurements when using this fraction is the variability of relative contents of quartz and feld-spars, which due to their differing behaviour influ-encing the equivalent dose (ED) and therefore its uncertai…

La pré-structure diégétique et le théâtre de la plénitude amoureuse ou deux visions de l'arbre dans la série romanesque d'Émile Zola, "Les Rougon-Mac…

2020

Artykuł analizuje dwie formy, jakie przybiera motyw drzewa w cyklu powieściowym Émile’a Zoli Rougon-Macquartowie. Pierwszą z nich, którą można nazwać „społeczną”, jest drzewo genealogiczne postaci tworzących powieściową rodzinę; sporządzenie tego drzewa i przygotowanie szczegółowych informacji na temat każdego bohatera i jego losów poprzedziło rozpoczęcie pracy nad cyklem, co czyni z niego rodzaj pra-struktury całej serii. Drugą formą, w jakiej drzewo pojawia się w analizowanych tekstach, jest forma „naturalna”, związana z przyrodą (drzewo jako roślina) i nasycona symboliką dotykającą miłości i płodności. Obie formy łączy odniesienie do życia jako nadrzędnej wartości i podstawowego tematu l…
