Innovative systems for the redevelopment of historical buildings: BIM application
2018
Il settore delle costruzioni sta vivendo una profonda trasformazione dovuta all’impiego di Tecnologie dell’Informazione che stanno modificando il modo di vivere, di lavorare, di produrre e di scambiare informazioni (BIM). Il BIM supera alcuni limiti della tradizionale organizzazione dell’attività progettuale, fatta di passaggi sequenziali tra i professionisti dei diversi settori per la definizione dei vari aspetti del progetto. Per tale ragione, in anni recenti, è cresciuto il suo uso come strumento di controllo e gestione del progetto di architettura sia per gli edifici di nuova costruzione che per la ri-funzionalizzazione di quelli esistenti. L’articolo presenta i risultati di uno studio …
Inhibitory activities of short linear motifs underlie Hox interactome specificity in vivo
2015
Hox proteins are well-established developmental regulators that coordinate cell fate and morphogenesis throughout embryogenesis. In contrast, our knowledge of their specific molecular modes of action is limited to the interaction with few cofactors. Here, we show that Hox proteins are able to interact with a wide range of transcription factors in the live Drosophila embryo. In this context, specificity relies on a versatile usage of conserved short linear motifs (SLiMs), which, surprisingly, often restrains the interaction potential of Hox proteins. This novel buffering activity of SLiMs was observed in different tissues and found in Hox proteins from cnidarian to mouse species. Although th…
Contributions Regarding Incremental Forming Process of Bimetallic Sheets
2014
Incremental forming is a process with a high degree of novelty, so this paper describes first of all a series of theoretical principles of the incremental forming process. A main objective of the paper was the usage, as blanks in incremental forming process of bimetallic sheets. So the experimental researches have targeted the realising of parts with different shapes made from such type of blank. In the experimental researches was chosen as technological equipment for incremental forming the numerical controlled milling centre. The paper also present the tools used in incremental forming in order to obtain a hemispherical parts.
SIGA3D: Semantic Combination of IFC and GIS to support Urban Facilities Management
2011
The interoperability of Information Systems has been a research topic for over thirty years. While some forms of heterogeneity have been settled by the adoption of standards, some domains, such as the Urban Information Modeling (UIM), require specific research. The UIM combines information from the domain of Building Information Modeling (BIM) with Geographic Information System (GIS) within a collaborative platform. Using this platform, a set of heterogeneous actors takes part in the lifecycle of the urban environment through a 3D digital model. This ambition is faced with several gaps such as resolution of semantic heterogeneity in the lifecycle management system, the resolution of structu…
Two Methods to Broaden the Bandwidth of a Nonlinear Piezoelectric Bimorph Power Harvester
2017
We propose two methods to broaden the operation bandwidth of a nonlinear pinned–pinned piezoelectric bimorph power harvester. The energy-scavenging structure consists of a properly poled and electroded flexible bimorph with a metallic layer in the middle, and is subjected to flexural vibration. Nonlinear effects at large deformations near resonance are considered by taking the in-plane extension of the bimorph into account. The resulting output powers are multivalued and exhibit jump phenomena. Two methods to broaden the operation bandwidth are proposed: The first method is to extend the operation frequency to the left single-valued region through optimal design. The second method is to exc…
Secretion and Metabolism of Ecdysteroids by Oenocyte-Fat Body Complexes (OEFC) in Adult Males of Gryllus bimaculatus DEG (Insecta)
1994
Extracts of whole adult males of Gryllus bimaculatus show distinct maxima of free ecdysteroids on the 8th, 12th and 14th day after imaginal moult at a breeding temperature of 25 °C. Isolated OEFC of 11 days old males secrete in vitro free as well as conjugated ecdysteroids, although the latter predominate. The bulk of free ecdysteroids seem s to consist of E and 20 E according to their retention times in two HPLC systems. Apart from the polar ones, apolar m etabolites appear during incubation. By esterase the apolar metabolites are mostly split into polar ones, partly into 20 E and E. Further treatment of the polar metabolites with helicase leads again to E and 20 E. OEFC transform [3H]E pr…
Land invertebrates of Columbretes Islands : new species
2020
Este artículo se encuentra disponible en la siguiente URL: https://www.mdpi.com/2071-1050/13/4/1776 La fauna terrestre de invertebrados del archipiélago protegido de Columbretes es poco conocida. Además, los pocos estudios existentes se centran en su isla principal, Illa Grossa. Aquí presentamos el listado de espe-cies de invertebrados no registradas, hasta el momento, en el archipiélago, resultados obtenidos mediante una combinación de capturas con trampas de caída, avistamientos y recolecciones aleatorias realizadas tanto en Illa Grossa como en otros tres islotes de este archipiélago. Mediante el primer método se recolectaron un total de 14.830 especímenes entre 2008-2011. La mayor cantid…
The EDTA Family of Molecular Based Ferromagnets
1991
The bimetallic compounds of the EDTA family offer a large variety of ferrimagnetic model systems in which the dimensionality as well as the exchange-anisotropy can be controlled with ease. This paper deals with the magneto-structural chemistry of this kind of materials, paying particular attention to both the low-dimensional magnetic behavior and the three-dimcnsional magnetic ordering.

2000
The first part of this thesis presents some theoretical and experimental results about modulational instability and domain wall solitons in bimodal fibers.In the second part is devoted to the interaction of counter-propagating waves in an isotropic optical fiber
An analysis of trade-offs in immune function, body size and development time in the Mediterranean Field Cricket, Gryllus bimaculatus
2005
Summary 1Immune defence has recently been viewed as a life-history trait that shows trade-offs with other life-history traits. However, studies exploring correlations between different components of immune defence and other life-history traits are scarce. 2In this study, two measures of immune function, body size, and development time were studied in the Mediterranean Field Cricket, Gryllus bimaculatus. 3We found no differences between the sexes, but differences in the correlation between the measure of immune function, development time, and body size. In both sexes, encapsulation rate was negatively correlated with body size and development time, whereas lytic enzyme activity was positivel…
