Ab Initio Liquid Water Dynamics in Aqueous TMAO Solution
2015
Ab initio molecular dynamics (AIMD) simulations in trimethylamine N-oxide (TMAO)-D2O solution are employed to elucidate the effects of TMAO on the reorientational dynamics of D2O molecules. By decomposing the O-D groups of the D2O molecules into specific subensembles, we reveal that water reorientational dynamics are retarded considerably in the vicinity of the hydrophilic TMAO oxygen (O(TMAO)) atom, due to the O-D···O(TMAO) hydrogen-bond. We find that this reorientational motion is governed by two distinct mechanisms: The O-D group rotates (1) after breaking the O-D···O(TMAO) hydrogen-bond, or (2) together with the TMAO molecule while keeping this hydrogen-bond intact. While the orientatio…
Conformational investigations of bis(α-aminoalkyl)phosphinic acids and studies of the stability of their complexes with Cu(II)
2008
Abstract Conformational investigations of a group of bis(α-aminoalkyl)phosphinic acids were performed by use of NMR spectroscopy and theoretical calculations. In the case of one of the studied compounds, substituted with aminobenzyl and amino(p-chlorobenzyl) moieties, a pH-dependent equilibrium between conformers, stabilized by intermolecular hydrogen bonds was observed. Potentiometric studies proved that these molecules formed stable complexes with copper(II) ions, where stoichiometry was 1:1 and 1:2 depending on pH of their aqueous solution.

orthoFind Facilitates the Discovery of Homologous and Orthologous Proteins
2015
Finding homologous and orthologous protein sequences is often the first step in evolutionary studies, annotation projects, and experiments of functional complementation. Despite all currently available computational tools, there is a requirement for easy-to-use tools that provide functional information. Here, a new web application called orthoFind is presented, which allows a quick search for homologous and orthologous proteins given one or more query sequences, allowing a recurrent and exhaustive search against reference proteomes, and being able to include user databases. It addresses the protein multidomain problem, searching for homologs with the same domain architecture, and gives a si…
Light-induced opening and closing of the intramolecular hydrogen bond in glyoxylic acid.
2013
The isomerization process of glyoxylic acid (GA) conformers and their complexes with a water molecule were studied in a low temperature argon matrix. The research target was to understand how starting conformation and complexation affects the near-IR (NIR) induced conformer interconversion. The most stable GA conformer (Tc) is characterized by an intramolecular hydrogen bond, and it is found to undergo light-induced conformer interconversion slower than the open (Tt) conformer. Upon complexation with water, the isomerization processes slow down in the case of the Tc conformer, whereas for the Tt-based complex the influence of water is negligible on the isomerization process.
Riflessioni sulla gerarchia militare
2020
The principle of hierarchy represents for the Armed Forces the organizational formula that guarantees the compactness of management and command through unity of action. In this sense, the hierarchy has always been considered an interpersonal institutional relationship model, inherent in the discipline, essential for the performance of institutional tasks. The hierarchy, in fact, constitutes the backbone of the Armed Forces, as a paradigmatic structure of authority, which conditions the entire life of the organization and reverberates in the context of the inter-individual relations of the military within the system. The paper intends to analyze the profiles characterizing the military hiera…
La dimensione giuridica dell'etica militare
2020
Unlike what happens for the civil administration, in which it conforms exclusively from a reputational perspective, the legal dimension of military ethics has a profile of characterization related, not only to the functions attributed to the Armed Forces, but, more precisely, to the role that they have in the constitutional structure. Military ethics has, in fact, an external declination, based on the neutrality of the military instrument with respect to political dynamics as an institution of guarantee and defense of republican institutions; and an internal, intimate interpretation connected to the organization as a factor of cohesion and functionality of the same in the framework designed…
La questione dell’autorizzazione ministeriale per le associazioni sindacali dei militari
2021
In according of CEDU in Italy trade union freedom is a right also recognized to members of the Armed Forces, but subject to limitations due to the functional aspect of the tasks institutional attributed. The peculiarity of the military organization reverberates in working relationships e gives trade union activity a special characterization with respect to the framework of trade union rights common. From the point of view of the specialty, the question of the preventive ministerial scrutiny of the legitimacy to carry out this activity which, according to the Council of State, stands out for a high degree of discretion. This statement leads us to believe that the establishment of an associat…

Sull’esecuzione delle sentenze tributarie nei confronti dell’Agenzia delle dogane
2019
Article 69 of Legislative Decree 546/92, in the current version, incorporates the principle of immediate enforceability of all judicial tax decisions, including those favorable to taxpayers. However, the Customs Agency, following a wrong interpretation of article 68, paragraph 3 bis, of Legislative Decree 546/92 and of the European regulations referred to therein, considers the above mentioned principle unapplicable with regards to non-definitive decisions concerning the European Union's own resources. A systematic interpretation of the rules leads to the conclusion that even these decisions are immediately enforceable.
