Nonni caregiver e famiglie headed by grandparents
2020
The volume begins with a reflection on the multiple and changing forms that contemporary families have assumed. The new trends in the social sciences emphasize, in fact, an increasingly accentuated gap between the nuclear family, a union between "the social and the legal" and a multitude of new family models, a synthesis of choices and assumptions of responsibility in the perspective of care and of the well-being of the other. There are numerous studies that in the most recent period investigate the transformation of the family, an institution present in all human societies. Subject analyzed by different disciplines and with multiple cuts, it has represented a cornerstone of anthropological…
The “nitrogen effect” : Complexation with macrocycles potentiates fused heterocycles to form halogen bonds in competitive solvents
2023
Weak intermolecular forces are typically very difficult to observe in highly competitive polar protic solvents as they are overwhelmed by the quantity of competing solvent. This is even more challenging for three-component ternary assemblies of pure organic compounds. In this work, we overcome these complications by leveraging the binding of fused aromatic N-heterocycles in an open resorcinarene cavity to template the formation of a three-component halogen-bonded ternary assembly in a protic polar solvent system. peerReviewed
Side‐on Coordination in Isostructural Nitrous Oxide and Carbon Dioxide Complexes of Nickel
2021
Abstract A nickel complex incorporating an N2O ligand with a rare η2‐N,N′‐coordination mode was isolated and characterized by X‐ray crystallography, as well as by IR and solid‐state NMR spectroscopy augmented by 15N‐labeling experiments. The isoelectronic nickel CO2 complex reported for comparison features a very similar solid‐state structure. Computational studies revealed that η2‐N2O binds to nickel slightly stronger than η2‐CO2 in this case, and comparably to or slightly stronger than η2‐CO2 to transition metals in general. Comparable transition‐state energies for the formation of isomeric η2‐N,N′‐ and η2‐N,O‐complexes, and a negligible activation barrier for the decomposition of the lat…
Un estudi exploratori sobre el procés de modelització amb dades reals en l'entorn informàtic dels iPads
2013
El treball d’investigació que presentem és un estudi exploratori sobre l’ensenyament i l’aprenentatge del procés de modelització d’una situació real en un grup d’alumnes de 1r de batxillerat. La peculiaritat d’aquest estudi és l’ús de dades reals obtingudes a partir de la gravació d’un vídeo del fenomen estudiat utilitzant iPads®. En particular, el model d’ensenyament que utilitzem permet treballar els conceptes de paràmetre i família de funcions i fa èmfasi en l’anàlisi qualitatiu del fenomen. The research work that we present is an exploratory study about teaching and learning the modelling process of a real situation in a grade 11 student group. The peculiarity of this study is the usage…
Metaphorical dimension of idioms in TV series for German, Norwegian and Spanish audiences
2022
Over recent years, internet TV series have grown in popularity to become one of the audiovisual products with the highest audiences worldwide. The Covid crisis, with limitations on movement, has further increased their success during 2020-21. English is by far the most common language for such productions, which are typically offered to non-anglophone viewers in translated format, with either subtitles or dubbing. One of the main challenges in translation here concerns the use of idioms, since these do not always have a fixed equivalent in the target language. Taking as a starting point a corpus of drama series from Netflix and Amazon Prime, this study considers the metaphorical dimension o…
Vīriešu iesaistīšanās Forums Celies aktivitātēs: vīrišķības analīze
2021
Bakalaura darbā "Vīriešu iesaistīšanās “Forums Celies” aktivitātēs: vīrišķības analīze" es apskatu iemeslus, kādēļ vīrieši iesaistās dzimtes jautājumu aktualizēšanā, ja vīrieši kā grupa un/ vai viņu īstenotā vīrišķība tiek skatīta kā problemātika. Lietojot teoriju par vīrišķībām un dzimtes kārtības varas attiecībām, analizēju daļēji strukturētās intervijās un līdzdalīgajā novērojumā iegūtus datus par to, kā iniciatīvas "Forums Celies" dalībnieki pieredz pastāvošo dzimtes kārtību un savu lomu tās izmaiņā. Darbā secinu, ka dalībnieku praktizētajai “veselīgajai vīrišķībai” ir hibrīdisks, ambivalents raksturs – tā ir viņiem pašiem un citiem palīdzoša un vienlaicīgi arī pastāvošo varas attiecību…
Halogen bonding and host-guest chemistry between
2019
Single crystal X-ray structures of halogen-bonded assemblies formed between host N-hexylammonium resorcinarene bromide (1) or N-cyclohexylammonium resorcinarene chloride (2), and 1,4-diiodooctafluorobutane and accompanying small solvent guests (methanol, acetonitrile and water) are presented. The guests’ inclusion affects the geometry of the cavity of the receptors 1 and 2, while the divalent halogen bond donor 1,4-diiodooctafluorobutane determines the overall nature of the halogen bond assembly. The crystal lattice of 1 contains two structurally different dimeric assemblies A and B, formally resulting in the mixture of a capsular dimer and a dimeric pseudo-capsule. 1H and 19F NMR analyses …
Solvothermal Synthesis of Molybdenum–Tungsten Oxides and Their Application for Photoelectrochemical Water Splitting
2018
Molybdenum and tungsten oxides are of interest as semiconductors for the production of clean and sustainable energy. Here we show that synergistic effects arising from a combination of noncrystalli...
Comparative study of initial stages of copper immersion deposition on bulk and porous silicon
2013
Initial stages of Cu immersion deposition in the presence of hydrofluoric acid on bulk and porous silicon were studied. Cu was found to deposit both on bulk and porous silicon as a layer of nanoparticles which grew according to the Volmer-Weber mechanism. It was revealed that at the initial stages of immersion deposition, Cu nanoparticles consisted of crystals with a maximum size of 10 nm and inherited the orientation of the original silicon substrate. Deposited Cu nanoparticles were found to be partially oxidized to Cu2O while CuO was not detected for all samples. In contrast to porous silicon, the crystal orientation of the original silicon substrate significantly affected the sizes, dens…
Modeling of the N-terminal Section and the Lumenal Loop of Trimeric Light Harvesting Complex II (LHCII) by Using EPR
2015
The major light harvesting complex II (LHCII) of green plants plays a key role in the absorption of sunlight, the regulation of photosynthesis, and in preventing photodamage by excess light. The latter two functions are thought to involve the lumenal loop and the N-terminal domain. Their structure and mobility in an aqueous environment are only partially known. Electron paramagnetic resonance (EPR) has been used to measure the structure of these hydrophilic protein domains in detergent-solubilized LHCII. A new technique is introduced to prepare LHCII trimers in which only one monomer is spin-labeled. These heterogeneous trimers allow to measure intra-molecular distances within one LHCII mon…
