The Impact of a 1,2,3-Triazole Motif on the Photophysical Behavior of Non-K Tetrasubstituted Pyrene with a Substitution Pattern Providing the Long Ax…

2022

1,3,6,8-Tetrasubstituted pyrene derivatives with two types of substituents (4-(2,2-dimethylpropyloxy)pyridine, 1-decyl-1,2,3-triazole, 1-benzyl-1,2,3-triazole, and pyrazole), substituted in such a way that provides the long axial symmetry, are prepared and characterized in the present study. To the best of our knowledge, the pyrene derivative containing the same heteroaryl motif (triazole) but substituted by two various alkyls, straight decyl and benzyl-based side chains (C), is reported for the first time. For comparison, compounds with one kind of triazole motif and substituted pyridine or pyrazole groups were prepared (A and B). The photophysical properties of all molecules were evaluate…

Acid–base properties of functionalised tripodal polyamines and their interaction with nucleotides and nucleic acids

2010

Novel, highly positively charged tripodal polyamines with appended heterocyclic moieties revealed an intriguing panel of protonation species within the biologically relevant range. Studied compounds bind nucleotide monophosphates by mostly electrostatic interactions but only the imidazole analogue showed selectivity toward UMP in respect to other nucleotides. Strong binding of all the studied compounds to both ds-DNA and ds-RNA is to some extent selective toward the latter, showing rather rare RNA over DNA preference.

Verità e discorso. Heidegger e la fenomenologia aristotelica

2022

The research critically examines the attribution to Aristtele of the fatal aporia between the phenomenological instance of an intuitive and pre-categorical truth and the hermeneutic instance of an originally linguistic articulation of the truth itself conducted by Heidegger radicalizing the polarization between the truth of the nous and the truth of dianoia. At the same time, the value of Heidegger's reading is highlighted, which inaugurates a phenomenological direction of Aristotelian studies inspired by the assumption that for the Stagirite concrete realities must be understood starting from a concretion of physis and logos. The phenomenological approach according to which there is no nee…

An experimental and theoretical study of a heptacoordinated tungsten(VI) complex of a noninnocent phenylenediamine bis(phenolate) ligand

2018

Abstract [W(N2O2)(HN2O2)] (H4N2O2 = N,N′-bis(3,5-di-tert-butyl-2-hydroxyphenyl)-1,2-phenylenediamine) with a noninnocent ligand was formed by reaction of the alkoxide precursor [W(eg)3] (eg = the 1,2-ethanediolate dianion) with two equivalents of ligand. The phenol groups on one of the ligands are completely deprotonated and the ligand coordinates in a tetradentate fashion, whereas the other ligand is tridentate with one phenol having an intact OH group. The molecular structure, magnetic measurements, EPR spectroscopy, and density functional theory calculations indicate that the complex is a stable radical with the odd electron situated on the tridentate amidophenoxide ligand. The formal ox…

Type-2 intuitionistic fuzzy TODIM for intelligent decision-making under uncertainty and hesitancy

2022

AbstractThe classical TODIM considers the crisp numbers to handle the information. However, in a real-world applicative context, this information is bounded by noise and vagueness and hence uncertain. There are wide range of works in the literature which utilizes fuzzy sets to handle the uncertainty in the various dimensions. However, there is a constraint of hesitancy in such decision-making problems due to the involvement of various decision-makers. Also, in the TODIM method, decision-maker’s bounded rationality and psychological behavior are also taken into consideration which adds up the hesitation and considers the problem with higher dimension of uncertainty. There are various applica…

Promoting Cooperation between Educational Institutions and Workplaces : Models of Integrative Pedagogy and Connectivity Revisited

2020

This theoretical review reflects on the development and application of the Integrative Pedagogical model as well as the Connective model investigating the organisation of learning in the interface between educational institutions and workplaces. The article explores the aspects that these two models emphasise, and identifies similarities and differences between them. Key studies on these approaches were reviewed to accomplish the task. The review shows how integrative pedagogy takes the individual’s learning as its starting point and how educators can support students by encouraging them to combine theoretical knowledge, experience and self-regulation in learning. While this model is pedago…

Problema fonetyčnoji transkrypciji napivpomjakšenych pryholosych u pidručnykach z ukrajins'koji movy jak inozemnoji

2020

L'articolo ha come obiettivo l'elaborazione di una proposta di trascrizione fonetica delle consonanti semipalatalizzate in ucraino per mezzo dei simboli dell'Alfabeto fonetico internazionale, da usare nei manuali destinati agli studenti stranieri. Vengono prese in considerazione diverse problematiche, tra cui: la limitatezza dei mezzi grafici dell'alfabeto fonetico per esprimere alcune particolarità della correlazione palatale; la resa ortografica delle semi-palatalizzate in ucraino e la sua corrispondenza alla loro pronuncia comune; la tendenza di alcune consonanti palatalizzate all'indurimento e i diversi modi di pronunciare le semi-palatalizzate. Nel lavoro vengono analizzati i contribut…

Terapia trans-cranica ad ultrasuoni focalizzati guidati da Risonanza Magnetica: studio retrospettivo di semeiotica neuroradiologica intra-operatoria

2019

SCOPO DEL LAVORO: Valutare retrospettivamente le caratteristiche di semeiotica neuroradiologica delle lesioni indotte in pazienti sottoposti a talamotomia unilaterale del nucleo Vim mediante l’utilizzo di un sistema trans-cranico ad ultrasuoni focalizzati guidati da RM (tcMRgFUS). MATERIALI E METODI: Cinquanta pazienti sono stati sottoposti a talamotomia mediante tcMRgFUS per tremore essenziale refrattario a terapia medica (n = 39) o per tremore in malattia di Parkinson (n = 11). Esaminando sequenze FRFSE T2-pesate (2mm, no gap) acquisite sia intra-operatoriamente che nel successivo follow-up RM a 48h, è stata valutata la presenza e le dimensioni delle aree lesionali concentriche precedente…

2018

Scopo Negli ultimi anni la terapia transcranica ad ultrasuoni focalizzati guidati da risonanza magnetica (tcMRgFUS) per il trattamento di disordini neurologici quali il tremore essenziale (ET) e il Parkinson tremorigeno (PD) è stata effettuata utilizzando esclusivamente scanner RM da 3T. Presentiamo i risultati ottenuti con il primo sistema tcMRgFUS mai integrato con uno scanner RM da 1.5T. Materiali e metodi 23 pazienti (19 ET; 4 PD) sono stati selezionati per essere sottoposti a tcMRgFUS (talamotomia monolaterale; target: nucleo ventrale intermedio, VIM). I pazienti arruolati sono stati valutati prima del trattamento e 2 giorni dopo. L'efficacia del trattamento è stata valutata utilizzand…
