L’antropologia filosofica di Remo Cantoni: umanismo critico, “connessione orizzontale” e partecipazione

2016

The paper proposes a critical reflection on Remo Cantoni’s philosophical thought, with particular regards to his anthropological point of view that addresses concepts such as “critical humanism” and “horizontal connection”. The strict relationship between anthropology and participation are his main topics on which he has made outstanding remarks in the second decade of XXth century in the Italian cultural panorama. Since his early works, Cantoni points out the need to develop a different way of analysing the pluridimensionality of human beings and widely debates contemporary European cultural context after the end of World War II. The paper tries to put in evidence how Cantoni’s anthropolog…

A silicon photomultiplier-based analog front-end for DC component rejection and pulse wave recording in photoplethysmographic applications

2022

The growing attention towards healthcare and the constant technological innovations in the field of semiconductor components have allowed a widespread availability of smaller devices, suitable to be worn and able to continuously acquire physiological signals. Wearable devices are, however, more prone to yield signals corrupted by artifacts caused by movement. This issue is particularly relevant in photoplethysmographic (PPG) applications where also, to exploit the whole dynamic range of the acquisition device, the DC component of the signal should be removed and the AC component amplified. In this context, we have designed and realized an analog front-end (AFE) suitable to be integrated wit…

Synthesis, characterization, and cellular investigations of porphyrin– and chlorin–indomethacin conjugates for photodynamic therapy of cancer

2021

Indomethacin is a potent non-steroidal anti-inflammatory drug (NSAID) with a strong selective inhibitor activity towards cyclooxygenase-2 (COX-2), an enzyme that is highly overexpressed in various tumour cells, being involved in tumourigenesis. Concomitantly, porphyrins have gained much attention as promising photosensitizers (PSs) for the non-invasive photodynamic therapy (PDT) of cancer. Herein, we report the design, and determine the singlet oxygen generation capacity and in vitro cellular toxicity of porphyrin- and chlorin-indomethacin conjugates (P2-Ind and C2-Ind). Both the conjugates were obtained in high yields and were characterized by 1H, 19F and 13C NMR as well as by high resolut…

Extending the Power Range of a Solar Inverter

2018

Solar inverters feature a minimum and maximum limit of the maximum power point voltage. Overcoming these limits leads to a disconnection of the power equipment, thus wasting the solar energy. In this paper, a solution to extend the power range of a solar inverter is presented. The proposed solution extends he minimum maximum power point limit of a commercial solar inverter by means of a battery energy storage system, including a DC/DC power converter. The battery energy storage system is connected in series to the photovoltaic module. If the photovoltaic module voltage drops below the minimum maximum power point limit, the battery energy storage system is enabled thus boosting the input vol…

Initial validation of the Psychobiosocial States in Physical Education (PBS-SPE) scale

2018

The purpose of this cross-sectional investigation was to examine the item characteristics, factor structure, reliability, convergent validity, and nomological validity of the Psychobiosocial States in Physical Education (PBS-SPE) scale. In Study 1, a sample of 1,030 students (582 girls and 448 boys, 10 to 19-year-olds), drawn from middle or high schools, rated the intensity of the 20 items version of the PBS-SPE scale thinking about the feelings they had usually experienced in physical education classes. In Study 2, an additional sample of 1,025 students (578 girls, 447 boys, 10 to 19-year-olds), rated the 16 items of the final version of the scale. Two subsamples also completed an affectiv…

Structural and electronic elucidation of a N-heterocyclic silylene vanadocene adduct

2017

The solid and solution state structure of the vanadium(II) N‐ heterocyclic silylene (NHSi) complex, [(SiIPr)V(Cp)2] (1) is reported ( SiIPr: 1,3‐bis(2,6‐diisopropylphenyl)‐1,3‐diaza‐2‐silacyclopent‐4‐ en‐2‐ylidene). The electronic structure of 1 is probed using combination of magnetic measurements, EPR spectroscopy and computational studies. The V–Si bond strength and complex forming mechanism between vanadocene and NHSi ligand is elucidated using computational methods.   peerReviewed

Selective encapsulation and enhancement of the emission properties of a luminescent Cu(I) complex in mesoporous silica

2018

We describe a synthetic approach to prepare new luminescent silica‐based materials through the encapsulation of a neutral copper(I) complex inside the pores of mesoporous silica nanoparticles (MSN). The copper(I) complex is present, in the solid state, as two polymorphs, blue and yellow emissive, and in solution it shows a pale yellow color that is also mirrored by an emission in the yellow‐orange region of the electromagnetic spectrum. The X‐ray structures of single crystals have been obtained for both polymorphs. The complex encapsulation in MSN is achieved by its entrapment inside micelles followed by condensation of the silica source. Interestingly, the entrapment leads to the isolation…

Pilsētu izplešanās ietekmes novērtēšana un priekšlikumi adaptīvai urbānai attīstības plānošanai

2020

Nekontrolēta pilsētu izplešanās un nekoordinēta apdzīvojuma struktūras attīstība rada ekonomiskas, sociālas, sabiedrības veselības un vides kvalitātes ietekmes. Ietekmes var izteikt kā publiskā sektora un mājsaimniecības izmaksu slogu, ko būtu iespējams samazināt īstenojot autores izstrādāto adaptīvas urbānās attīstības plānošanas pieeju vai citas pilsētu izplešanās attīstības plānošanas pieejas.. Maģistra darba ietvaros tiek demonstrēts pilsētu izplešanās ietekmes novērtēšanas pieejas potenciāls, un sniegti priekšlikumi adaptīvas attīstības plānošanai, lai veicinātu datos balstītu lēmumu pieņemšanu, teritorijas pārvaldības un plānošanas spēju pielāgoties mūsdienu strauji mainīgajiem apstāk…

De participació local. Una proposta metodològica desde la investigació-acció-participativa

2018

Citizen participation is an increasingly prevalent term in our society. In the process of deployment in the municipal area, progressively local corporations make efforts to innovate practices and develop experiences of citizen participation in defining policies and public affairs, and allocating budgets. While innovation has been advanced with regard to the tools and mechanisms to be used to promote participation, many of the initiatives and experiences have focused more on the implementation of the vote than in the different social processes inherent in the participation. Moreover, we are faced with the absence of a methodological guide that allows approaching a project or strategic plan o…
