Zebrafish Fins as a Model System for Skeletal Human Studies
2007
Recent studies on the morphogenesis of the fins ofDanio rerio(zebrafish) during development and regeneration suggest that a number of inductive signals involved in the process are similar to some of those that affect bone and cartilage differentiation in mammals and humans. Akimenko et al. (2002) has shown that bone morphogenetic protein-2b (BMP2b) is involved in the induction of dermal bone differentiation during fin regeneration. Many other groups have also shown that molecules from the transforming growth factor-beta superfamily (TGFβ), including BMP2, are effective in promoting chondrogenesis and osteogenesisin vivoin higher vertebrates, including humans. In the present study, we review…
Experimental Evaluation on Narrow Band Power Line Communication in Medium and Low Voltage Smart Grids
2013
The aim of this work is to perform a feasibility study on the power line communication for the development of a new generation of interface devices (IDs) for smart grid and energy storage applications. More in detail, this paper deals with one of the most important issues on this topic, which is the communication system. Among the existing communication technologies, the study is focused on power line communications (PLCs). After an analysis of the state of the art in the field, the main aspects are analyzed, concerning the open issues on the use of PLCs, especially for medium voltage (MV) and low voltage (LV) systems. In this work the use of PLC in MV-LV networks is investigated, by means …
AMBIENTE COSTRUITO E SOSTENIBILITÀ – Materiali riciclati e Design for Disassembly tra ricerca e buone pratiche
2020
In the context of environmental emergency of which the construction sector is one of the main causes – since it consumes 40% of the (embodied and operational) energy and produces about a third of the total waste – and due to the ambitious objectives set by the international community and by many countries to reduce the environmental impact of buildings during their whole life cycle, this paper wants to make a contribution to the understanding of the state of the art on cycle-based research activities, sustainable experiments and good practices that the building industry and the academy have implemented in recent years. In particular, it refers to cycle-based theoretical and experimental act…
Sur la prise en compte de quelques conditions aux limites avec la méthode des éléments finis
2017
Ce cours a pour principal sujet la discrétisation de certaines conditions limites sur le bord d'un domaine à l'aide de la méthode des éléments finis. Nous étudions en particulier des problèmes elliptiques avec conditions de Dirichlet non-homogènes, puis avec conditions de Signorini. Les conditions de Signorini sont des conditions de contact unilatéral entre un solide et un support rigide. Différentes méthodes sont passées en revue, et nous détaillons l'analyse pour les méthodes classiques et celle de Nitsche.
Commento agli artt. 341-346 c.p.p.
2008
Il commento ha ad oggetto le condizioni di procedibilità, in particolare l'istanza di procedimento, la richiesta di procedimento e l'autorizzazione a procedere, che vengono anzitutto inquadrate nel sistema e poi analizzate dall'Autrice mettendo in evidenza gli orientamenti giurisprudenziali e dottrinali più significativi. Viene analizzata altresì la disciplina in caso di difetto di una condizione di procedibilità, con apertura alla riproponibilità dell'azione, nonché quella relativa alla sorte degli atti compiuti in mancanza di una condizione di procedibilità.
Effetto della dimensione dell'anello sulla conducibilità idraulica del suolo saturo misurata con la tecnica SFH
2009
Nel lavoro è stata esaminata la relazione tra la conducibilità idraulica del suolo saturo, Kfs, misurata in campo con la tecnica Simplified Falling Head (SFH) e la dimensione della superficie campionata con una singola prova. L’indagine è stata condotta in un suolo franco-sabbioso ed in uno franco-limoso, esplorando la medesima superficie complessiva (0.71 m2) con anelli di diametro compreso tra 0.15 e 0.30 m. Nel suolo franco-sabbioso, le misure di Kfs effettuate con gli anelli piccoli sono risultate significativamente più elevate di quelle ricavate con gli anelli grandi. In particolare, i valori medi hanno mostrato una discrepanza di un fattore 1.7 e il ricorso agli anelli piccoli ha dete…

Il conflitto di interessi nelle cariche di governo: un nodo ancora irrisolto
2010
il saggio affronta il delicato e complesso problema del conflitto di interessi nell'esercizio delle cariche di governo, ancora irrisolto anche dopo la legge Frattini alla luce della proposta di legge presentata dai gruppi di maggioranza nella XIV legislatura.
An efficient Escherichia coli expression system for the production of a functional N-terminal domain of the T1R3 taste receptor.
2012
http://www.landesbioscience.com/; International audience; Sweet taste is mediated by a dimeric receptor composed of two distinct subunits, T1R2 and T1R3, whereas the T1R1/T1R3 receptor is involved in umami taste perception. The T1R1, T1R2, and T1R3 subunits are members of the small family of class C G protein-coupled receptors (GPCRs). The members of this family are characterized by a large N-terminal domain (NTD), which is structurally similar to bacterial periplasmic-binding proteins and contains the primary ligand-binding site. In a recent study, we described a strategy to produce a functional dimeric human T1R3-NTD. Although the protein was expressed as inclusion bodies (IBs) using the …
Bleomycin, a selective inhibitor of DNA-dependent DNA polymerase from oncogenic RNA viruses.
1972
Abstract Bleomycin, an antibiotic, inhibits the DNA-dependent DNA polymerase from Rauscher murine leukemia virus. Higher concentrations of BLM ∗ are required to inhibit it's RNA-dependent DNA polymerase. These inhibition effects of the non-competitive type are not altered by preincubation of the DNA with BLM. Under comparable conditions neither the DNA-dependent DNA polymerase activity from E. coli and mouse liver nor the DNA-dependent RNA polymerase activity from mouse lymphoma cells are affected by BLM.
