A Computational Study of Adsorption of CO2, SO2, and H2CO on Free-Standing and Molybdenum-Supported CaO Films
2018
Oxide films play a significant role in a wide range of fields from catalysis to solar cell materials. CaO films are promising sorbents for many environmentally harmful molecules. Here, we report a systematic investigation of adsorption of CO2, SO2, and H2CO on bulk and Mo-supported CaO(100) films using density functional theory. Significant effects on adsorption energy, charge transfer to the molecules, and degree of the C–O bond activation were demonstrated on Mo-supported CaO films by changing the film thickness, composition, and the strength and direction of an applied external electric field. These findings are relevant for interpreting results from scanning tunneling microscopy of smal…

2023
Funding Information: The work at Aalto University has been financially supported by the Academy of Finland (COOLCAT consortium, decision no. 329977 and 329978 ; ALDI consortium, decision no. 331082 ). This work made use of Aalto University Bioeconomy, OtaNano and RawMatters infrastructure. Hannu Revitzer (Aalto University) is thanked for the ICP-OES analysis, Aalto workshop people (especially Seppo Jääskeläinen) for working on the reactor modifications. The DFT calculations were made possible by computational resources provided by the CSC — IT Center for Science, Espoo, Finland ( https://www.csc.fi/en/ ) and computer capacity from the Finnish Grid and Cloud Infrastructure (urn:nbn:fi:resear…
The ABCflux database: Arctic-boreal CO2flux observations and ancillary information aggregated to monthly time steps across terrestrial ecosystems
2022
Past efforts to synthesize and quantify the magnitude and change in carbon dioxide (CO2) fluxes in terrestrial ecosystems across the rapidly warming Arctic–boreal zone (ABZ) have provided valuable information but were limited in their geographical and temporal coverage. Furthermore, these efforts have been based on data aggregated over varying time periods, often with only minimal site ancillary data, thus limiting their potential to be used in large-scale carbon budget assessments. To bridge these gaps, we developed a standardized monthly database of Arctic–boreal CO2 fluxes (ABCflux) that aggregates in situ measurements of terrestrial net ecosystem CO2 exchange and its derived partitioned…
Prenatal Exposure to Δ9-Tetrahydrocannabinol Affects Hippocampus-Related Cognitive Functions in the Adolescent Rat Offspring: Focus on Specific Marke…
2023
Previous evidence suggests that prenatal exposure to THC (pTHC) derails the neurodevelopmental trajectories towards a vulnerable phenotype for impaired emotional regulation and limbic memory. Here we aimed to investigate pTHC effect on hippocampus-related cognitive functions and markers of neuroplasticity in adolescent male offspring. Wistar rats were exposed to THC (2 mg/kg) from gestational day 5 to 20 and tested for spatial memory, object recognition memory and reversal learning in the reinforce-motivated Can test and in the aversion-driven Barnes maze test; locomotor activity and exploration, anxiety-like behaviour, and response to natural reward were assessed in the open field, elevate…

Disegno, progetto e anima dei luoghi
2019
Il libro "Quadri per Milano - prove di architettura" (LetteraVentidue, 2017) raccoglie nove progetti su Milano di Angelo Torricelli, elaborati tra il 1991 e il 2017 e ordinati secondo la loro posizione all'interno della città e le soluzioni adottate. Il volume, concepito come il catalogo della mostra organizzata presso il Dipartimento di Architettura di Palermo, ha assunto il carattere di una riflessione con diverse voci sulle relazioni tra rappresentazione / progetto / luogo. I testi intenzionalmente scarsi (dell'autore), che accompagnano i progetti, indicano esclusivamente i motivi e gli obiettivi delle proposte. I tre saggi iniziali e quello conclusivo, d'altra parte, propongono un parti…
Envers un repertori conceptual de la poesia de Narcís Vinyoles
2013
Resum: L’obra lírica de Narcís Vinyoles es pot caracteritzar pel sincretisme formal i temàtic, típic de la València del pas del segle XV al XVI, un espai eclèctic on s’unien influències diverses. En aquest espai receptor Vinyoles construí la seua obra amb tres llengües: català, castellà i italià, i amb inspiracions temàtiques divergents. Des del punt de vista temàtic, un dels elements barrejats pel poeta valencià fou el filosoficoconceptual. En aquest treball detectaré els conceptes i, sense explicarlos en profunditat, explicitaré l’ús que en fa el poeta valencià. Dividiré el repertori conceptual en cinc apartats, segons la disciplina a la qual pertanguen: epistemologia, filosofia de la nat…
Social, health care and rehabilitation educators' competence in professional education—Empirical testing of a model
2021
The social and health care educator's role in educating future professionals need to be stronger emphasised and deserves international recognition. The purpose of this study was to develop and test an empirical model of social and health care educators' competence in higher and professional education. The presented research employed a cross-sectional study design. Data were collected using HeSoEduCo-instrument from 28 educational institutions in Finland. The model was empirically tested with confirmatory factor analysis through Structural Equation Modelling that applied the Full Imputation Maximum Likelihood estimator. A total of 422 social and health care educators participated in the stud…
Social, health and rehabilitation sector educators’ competence in evidence-based practice : A cross-sectional study
2021
Aim: The purpose of the study was to identify and describe the characteristic profiles of evidence-based practice competence of educators in the social, health and rehabilitation sectors and to establish relevant background factors. Design: This study was carried out as a descriptive cross-sectional study. Methods: Data were collected from social, health and rehabilitation sector educators working in the 21 Finnish universities of applied sciences and seven vocational colleges (n = 422; N = 2,330). A self-assessment instrument measuring evidence-based practice competence was used. Competence profiles were formed using a K-cluster grouping analysis. Results: Three distinct competence profile…
Aikuisten turvapaikanhakija- ja pakolaisasiakkaiden terapeuttisissa keskusteluissa kuvaamat hyödylliset muutokset
2018
Tutkimuksessa tarkastellaan sitä, kuinka kuusi aikuista turvapaikanhakija- ja pakolaisasiakasta kuvaavat kokemiaan hyödyllisiä muutoksia luonnollisissa terapeuttisissa keskusteluissa. Asiakkaiden keskustelukäynnit kriisikeskuksen työntekijöiden luona videotallennettiin. Tutkimuksen kohteena olivat asiakkaiden esittämät ja tulkkien suomeksi välittämät ilmaukset. Tutkimusmenetelmänä käytettiin aineistolähtöistä laadullista sisällönanalyysia. Analyysissä syntyi neljä hyödyllisen muutoksen kategoriaa. Hyödyllisen muutoksen kategorioita ovat helpottuneempi olotila, uusien ongelmiin ja elämään liittyvien hallintakeinojen omaksuminen, itseymmärryksen ja voimaantumisen tunteen lisääntyminen ja rake…
