Accordi e disaccordi sulla buona fede oggettiva
No full textl dovere di buona fede contrattuale ha avuto nel corso del tempo un andamento non lineare. Prima ignorata dalla giurisprudenza, in seguito è divenuta uno strumento fondamentale per integrare il contratto e per regolare l'esercizio dei poteri attribuiti alle parti del contratto. Anche di recente il confronto fra una decisione della Suprema Corte di Cassazione e una decisione della Corte Costituzionale italiana rendono evidente che di fronte a casi diversi per materia, ma simili per quanto concerne il ragionamento giuridico da porre a base della decisione, si possono registrare approcci più o meno convincenti

La fornace Bianchi in Cogoleto: una fornace ottocentesca in un paese che dall’epoca medievale ha prodotto ed esportato calce
No full textBianchi furnace in Cogoleto: an XIX century infrastructure in a town that produced and exported mortar since Middle Age. The mortar industry was the most important business in Cogoleto, near Genoa, since XVIII century, several witnesses confirm it. For this reason the restoration of this furnace, a single building, became a part of a larger project on restoration of urban identity for this town. Sometimes in the past this identity was even disclaimed, as it was linked to unhappy memories: health problems caused by powders, deforestation of adjoining areas, traffic problems due to freights load and unload on the shore. Mortar manufacturing was prosperous since XIV century, and it continued operations up to the end of XIX century, Another important activity was mortar transportation and commerce all over the Mediterranean sea. Limestone quarrels behind Cogoloto town are still visible today. In XVII century, during peak development of the business 12 furnaces were working in town, while in XIX century still 7 furnaces were open and active. Bianchi furnace belongs to a intermediate technology, in the passage between “discontinuous fire” and more recent “continuous fire” technology. This is one more reason for its restoration. The restoration process of this mortar furnace is now in progress, under the guide of the local administration (Comune di Cogoleto) that wanted it very firmly. Several experts from different experiences work on the study and analysis applied to the building element and even to quarrel sites. The archaeological analysis discovered tracks, of building history, and analysis on the written sources allowed an effective comparison
Spatial patterns of CTCF sites define the anatomy of TADs and their boundaries
Full text linkBackground: Topologically associating domains (TADs) are genomic regions of self-interaction. Additionally, it is known that TAD boundaries are enriched in CTCF binding sites. In turn, CTCF sites are known to be asymmetric, whereby the convergent configuration of a pair of CTCF sites leads to the formation of a chromatin loop in vivo. However, to date, it has been unclear how to reconcile TAD structure with CTCF-based chromatin loops. Results: We approach this problem by analysing CTCF binding site strengths and classifying clusters of CTCF sites along the genome on the basis of their relative orientation. Analysis of CTCF site orientation classes as a function of their spatial distribution along the human genome reveals that convergent CTCF site clusters are depleted while divergent CTCF clusters are enriched in the 5- to 100-kb range. We then analyse the distribution of CTCF binding sites as a function of TAD boundary conservation across seven primary human blood cell types. This reveals divergent CTCF site enrichment at TAD boundaries. Furthermore, convergent arrays of CTCF sites separate the left and right sections of TADs that harbour internal CTCF sites, resulting in unequal TAD 'halves'. Conclusions: The orientation-based CTCF binding site cluster classification that we present reconciles TAD boundaries and CTCF site clusters in a mechanistically elegant fashion. This model suggests that the emergent structure of nuclear chromatin in the form of TADs relies on the obligate alternation of divergent and convergent CTCF site clusters that occur at different length scales along the genome.

Risoluzione per inadempimento Tomo I, 2
No full textCommentario alla norma del codice civile che richiede l'importanza dell'inadempimento ai fini dell'accoglimento della domanda di risoluzione del contratto. Il tema è trattato con riguardo ai problemi emersi nella pratica e trattati dalla giurisprudenza, sia per quanto riguarda la definizione generale del concetto e la sua collocazione sistematica nell'ambito della disciplina generale del contratto, sia in merito alla disciplina specifica dei singoli contratti e dunque alle applicazioni concrete
Morphological, Microstructural and Electrochemical Properties of RuO2-SnO2 Film Electrodes
No full textThe electrochemical devices based on conductive RuO2 stabilized by ceramic oxides are the most employed in chlorine-alkali cells.
Their efficiency is influenced by many variables, among which the chemical nature of the stabilizer oxide plays a considerable role.
In this paper, morphology, microstructure, and electrocatalytic properties of supported RuO2-SnO2 thin films, prepared in a wide
compositional range, were investigated by X-ray diffraction (XRD), scanning tunneling microscopy (STM), and cyclic voltammetry (CV). X-ray analysis indicates an immiscibility zone for the two oxides approximately in the range 20-70 atom % of Sn nominal amounts. In both solubility regions, a tetragonal phase (rutile-type) is formed. Peak profile analysis indicates a nonequiaxial crystal growth and shows that in solid solutions where RuO2 is the major component larger crystallites (about 100-160 Å) are formed than in those where SnO2 is the major component (about 30 Å). STM characterization reveals a rough surface with a complex microstructure: very large agglomerates, which seems to be made up of a large number of smaller units with sizes of the same order of magnitude found by XRD. Only in the sample with 70 atom % of Sn (nominal amounts) there exists regions where the small units are clearly visible as distinct particles. The CV analysis shows that the highest electrocatalytic activity is exhibited by the latter sample, which has the highest possible content of RuO2 before it forms a solid solution in SnO2 and where particles tend not to form aggregates
Metadata management for scientific databases
Full text linkMost scientific databases consist of datasets (or sources) which in turn include samples (or files) with an identical structure (or schema). In many cases, samples are associated with rich metadata, describing the process that leads to building them (e.g.: the experimental conditions used during sample generation). Metadata are typically used in scientific computations just for the initial data selection; at most, metadata about query results is recovered after executing the query, and associated with its results by post-processing. In this way, a large body of information that could be relevant for interpreting query results goes unused during query processing. In this paper, we present ScQL, a new algebraic relational language, whose operations apply to objects consisting of data–metadatapairs, by preserving such one-to-one correspondence throughout the computation. We formally define each operation and we describe an optimization, called meta-first, that may significantly reduce the query processing overhead by anticipating the use of metadata for selectively loading into the execution environment only those input samples that contribute to the result samples. In ScQL, metadata have the same relevance as data, and contribute to building query results; in this way, the resulting samples are systematically associated with metadata about either the specific input samples involved or about query processing, thereby yielding a new form of metadata provenance. We present many examples of use of ScQL, relative to several application domains, and we demonstrate the effectiveness of the meta-first optimization
