Servizi bancari essenziali: il conto corrente
2022
The work proposes an analysis of the various tools that can be invoked to bridge some frictions of the credit system in areas where the banking "service" is characterized by essentiality, such as in the case of bank account. The inefficiency of the traditional code regulations emerges with particular evidence when the recourse to banking intermediation is imposed by specific rules functionality to public interests, as in case of imposed virtual currency payments. The incidence of the cost of the service, often not adequately remunerated by the price, can cause an indiscriminate selection of customers, permitted by contractual rules that authorize the end of the relationship without requirin…
Non-Innocent Base Properties of 3- and 4-Pyridyl-dithia- and Diselenadiazolyl Radicals : The Effect of N-Methylation
2018
International audience; Condensation of persilylated nicotinimideamide and isonicotinimideamide with sulfur monochloride affords double salts of the 3-, 4-pyridyl-substituted 1,2,3,5-dithiadiazolylium DTDA cations of the general formula [3-, 4-pyDTDA][Cl][HCl] in which the pyridyl nitrogen serves as a noninnocent base. Reduction of these salts with triphenylantimony followed by deprotonation of the intermediate-protonated radical affords the free base radicals [3-, 4-pyDTDA], the crystal structures of which, along with those of their diselenadiazolyl analogues [3-, 4-pyDSDA], have been characterized by powder or single-crystal X-ray diffraction. The crystal structures consist of “pancake” π…
A convenient route for the preparation of the monohydride catalyst trans-[RuCl(H)(dppe)2] (dppe=Ph2PCH2CH2PPh2): improved synthesis and crystal struc…
2013
Abstract A novel and improved room temperature synthesis of the monohydride catalyst trans-[RuCl(H)(dppe)2] complex (1, dppe (1,2-bis(diphenylphosphino)ethane) = Ph2PCH2CH2PPh2) proceeds through oxidation of methanol (the solvent) by the pentacoordinated cis-[RuCl(dppe)2][PF6] complex and t-BuOK as the base is described. Compound 1 was fully characterized by NMR (1H, 13C, 31P), ESI-MS(TOF +), FTIR and elemental analysis. The X-ray structure of 1 was reported for the first time and unambiguously confirms the trans-configuration of the complex.
Experimental Evaluation of the Performance of a Three-Phase Five-Level Cascaded H-Bridge Inverter by Means FPGA-Based Control Board for Grid Connecte…
2018
Over the last decades, plants devoted to the generation of green energy significantly increased their number, together with the demand of same electrical energy, also stored in battery systems. This fact produced the growth of energy conversion systems with advanced performances with respect to the traditional ones. In this circumstance, multilevel converters play a significant role for their great advantages in performances, flexibility, fault-tolerability, employment of renewable energy sources and storage systems and finally yet importantly reduced filter requirements. In this context, this paper faces the performance of a cascaded H-bridge 5 level inverter in terms of harmonic distortio…
A 9-level three-phase multilevel converter with harmonic mitigation and integrated battery balancing
2019
In this paper, a 9 level three-phase multilevel converter with a harmonic mitigation control method and an integrated battery balancing algorithm for automotive purpose is proposed. Each level of the converter is composed by a buck-boost converter and an h-bridge in cascaded connection. The control algorithm is implemented to achieve the harmonic mitigation on the output voltage waveform and to maintain the battery input voltages balanced. The design and operation of the system is described, and simulation study is reported using Matlab/Simulink platform.
Outoja omakuvia : performatiivisuus ja kokemus Alison Bechdelin omaelämäkerrallisessa sarjakuvaromaanissa Fun Home
2013
Analysoin tutkimuksessani Alison Bechdelin omaelämäkerrallista sarjakuvaromaania Fun Home. A Family Tragicomic (2006). Fun Home on omaelämäkerran lisäksi elämäkerta Alisonin isästä, Bruce Bechdelistä. Bruce tekee itsemurhan Alisonin ollessa noin kaksikymmentävuotias ja jättää jälkeensä joukon vastauksettomia kysymyksiä – Fun Homessa Alison pohtii näitä kysymyksiä ja vertailee Brucen elämäntarinaa omaansa. Alison identifioituu lesboksi ja epäilee myös Brucen olleen homoseksuaali. Teoksessa on runsaasti intertekstuaalisuutta: keskeinen subteksti on esimerkiksi Ikaroksen ja Daidaloksen myytti, jonka käänteinen uudelleenkerronta kuvaa Alisonin ja Brucen välistä suhdetta. Tutkimuksen tavoitteena…
Review about comorbidities of behavioural disorders in children and adolescents: The focus on attention-deficit/hyperactivity disorder
2017
Disruptive behavior disorders (DBD) present high comorbidity rate mainly for opposite-defiant disorders that are frequent among children, adolescents and adults affected by with attention deficit and hyperactivity disorder (ADHD), probably as result of common temperamental risk factors such as attention, distraction, impulsivity. ADHD tend to manifest in about 50% of individuals diagnosed as disruptive behavioral disorders.
A bending theory of thermoelastic diffusion plates based on Green-Naghdi theory
2017
Abstract This article is concerned with bending plate theory for thermoelastic diffusion materials under Green-Naghdi theory. First, we present the basic equations which characterize the bending of thin thermoelastic diffusion plates for type II and III models. The theory allows for the effect of transverse shear deformation without any shear correction factor, and permits the propagation of waves at a finite speed without energy dissipation for type II model and with energy dissipation for type III model. By the semigroup theory of linear operators, we prove the well-posedness of the both models and the asymptotic behavior of the solutions of type III model. For unbounded plate of type III…
Il diritto di recesso nelle società c.d. benefit
2020
This essay will examine legislations on benefit corporations across Europe and the US, through a focus on whether or not elections by a corporation – or any other entity – to become a social purpose corporation or to cease to be one entail the arising of a right to withdraw on dissenting shareholders. Starting with the analysis of the legal framework, which applies to operations such as conversions from a for-profit corporation to a benefit corporation or the other way around, the essay will investigate their effects on the right to withdraw of dissenting shareholders both on unincorporated business entities and on corporations.
