Experimental evidence for transverse wobbling bands in 136Nd
2022
The nature of two high-spin bands in 136Nd built on the two-quasiparticle configuration πh211/2, predicted by the triaxial projected shell model as good candidates of transverse wobbling bands, are investigated experimentally. The mixing ratio of one ΔI=1 transition connecting the one-phonon and the zero-phonon wobbling bands is established from a high-statistics JuroGam II γ-ray spectroscopy experiment by using the combined angular correlation and linear polarization method. The resulting wobbling excitation energy and ratios of reduced electromagnetic transition probabilities are in good agreement with results of a new particle-rotor model which rigidly couples the total angular momentum …
An IPMSM torque/weight and torque/moment of inertia ratio optimization
2014
In this paper, a torque/weight and torque/moment of inertia ratio optimization procedure for interior permanent magnet syncronous motors (IPMSMs) is presented. More in detail, a performance comparison between several IPMSM rotor structures has been carried out in order to determine the optimum geometry that can maximize the torque/weight and torque/moment of inertia ratios. A commercial motor, with known electrical and mechanical characteristics, has been taken as reference. Its rotor structure has been modified several times, obtaining different rotor geometries and, therefore, many IPMSM models with different electrical and mechanical characteristics. The finite element method (FEM) analy…

Cadmium Metal–Organic Frameworks Based on Ditopic Triazamacrocyclic Linkers: Unusual Structural Features and Selective CO 2 Capture
2017
International audience; Two three-dimensional cadmium metal organic frameworks with general formula [Cd-2(L-1)(H2O)(3)](NO3)(0.7)(HCOO)(0.2)Br-0.1 (Cd2L1, L-1 = 1,4,7-tris(4-carboxybenzy1)-1,4,7-triazacyclononane) and Cd(HL2)(H2O)(2) (CdL2, L-2 = 1,4,7-tris(3-(4-benzoate)prop-2-yn-1-yl)-1,4,7-triazacydononane) based on 1,4,7-triazacyclononane N-functionalized by different arylcarboxylic acids were prepared under solvothermal conditions and characterized by single crystal X-ray analysis and porosity measurements. The crystal structure of Cd2L1 reveals a cationic net with a bcs topology,. and nodes are constituted by dinuclear cadmium complexes, in which each cadmium atom adopts a hexacoordin…
Changes of meaning due to changes of articles: A study of singular count nouns in post-verbal position in Italian
2009
'Essi fecero un muro' vs. 'Essi fecero muro': on the surface, these Italian sentences differ only for the presence of an article before the post-verbal noun (PVN) 'muro', literally 'wall'. Despite this minor divergence, their VPs vary greatly in meaning: the former can be rendered as 'They built a wall', the latter as 'They put up resistance'. In Italian, many other nouns behave as 'muro' does above. The meanings come from distinct structures: PVNs preceded by an article are direct objects. Bare PVNs, at times the very same noun, can either pass tests for direct object-hood or show distinct syntactic ties with the verb.

Interplay between the Belousov-Zhabotinsky reaction-diffusion system and biomimetic matrices
2007
Abstract Interactions between reaction–diffusion systems and restricted host environments are a subject of widespread interest. In this work the behaviour of the Belousov–Zhabotinsky reaction was investigated in lamellar phases formed by phospholipid bilayers with relevance for biological systems. The influence of the reactive medium on the structure of the lipid matrix and, in turn, the influence of the matrix on the dynamical evolution of chemical patterns, were studied by small angle scattering.
