Noninvasive Flap Preconditioning by Foam-Mediated External Suction Improves the Survival of Fasciocutaneous Axial-Pattern Flaps in a Type 2 Diabetic …

2018

Background Advances in reconstructive surgery are leading to an increased number of flaps at risk for ischemic necrosis, because of either intrinsic (e.g., larger flap size) or extrinsic (e.g., diabetes) factors. Methods to preoperatively improve flap vascularity and limit postoperative ischemia are lacking. Noninvasive suction, using either a macrodeformational silicone cup interface (external volume expansion) or a microdeformational polyurethane foam interface (foam-mediated external volume expansion), has been shown to induce angiogenesis in tissues. The authors investigated whether the preoperative use of external volume expansion/foam-mediated external volume expansion improves flap s…

ASYMPTOTIC CURVES ON SURFACES IN ℝ5

2008

We study asymptotic curves on generically immersed surfaces in ℝ5. We characterize asymptotic directions via the contact of the surface with flat objects (k-planes, k = 1 - 4), give the equation of the asymptotic curves in terms of the coefficients of the second fundamental form and study their generic local configurations.

Study of High-Temperature Behaviour of ZnO by Ab Initio Molecular Dynamics Simulations and X-ray Absorption Spectroscopy

2021

Wurtzite-type zinc oxide (w-ZnO) is a widely used material with a pronounced structural anisotropy along the c axis, which affects its lattice dynamics and represents a difficulty for its accurate description using classical models of interatomic interactions. In this study, ab initio molecular dynamics (AIMD) was employed to simulate a bulk w-ZnO phase in the NpT ensemble in the high-temperature range from 300 K to 1200 K. The results of the simulations were validated by comparison with the experimental Zn K-edge extended X-ray absorption fine structure (EXAFS) spectra and known diffraction data. AIMD NpT simulations reproduced well the thermal expansion of the lattice, and the pronounced …

Design e narrazioni

2022

Il testo nasce dall’esigenza di mettere a fuoco le implicazioni cognitive, metodologiche e progettuali del concetto di narrazione, sempre più ricorrente nella nostra esperienza quotidiana soprattutto per le molteplici forme di comunicazione e di produzioni culturali che vi si ispirano; si tratta di un concetto che anche nella riflessione teorica e nella progettualità del design sta alimentando dimensioni fortemente innovative ed evolutive nella costruzione, comunicazione di significati, contenuti immateriali, esperienze e valori emozionali che si sovrappongono e s’intrecciano all’espressione tangibile e funzionale degli oggetti, degli artefatti comunicativi, degli spazi. Si propone un perco…

The text arises from the need to focus on the cognitive methodological and design implications of the concept of storytelling increasingly recurrent in our daily experience especially for the many forms of communication and cultural productions that are inspired by itSettore ICAR/13 - Disegno Industrialeit is a concept that also in theoretical reflection and design planning is feeding strongly innovative and evolutionary dimensions in the construction communication of meanings intangible content experiences and emotional values that overlap and intertwine with the tangible and functional expression of objects communicative artifacts spaces.. It proposes a cognitive path tangent to the development of "narratology" and the theories of narrationthus we come across a multiplicity of disciplinary connections affecting sociology psychology anthropology philosophy semiotics and of course history cinema journalism advertising up to corporate communication and political propaganda. It is an articulated panorama that today seems to expand more and more and far from being mainly addressed to theoretical issues increasingly seems to be modeled on application performative and design aspects.

Analog Multiple Description Joint Source-Channel Coding Based on Lattice Scaling

2015

Joint source-channel coding schemes based on analog mappings for point-to-point channels have recently gained attention for their simplicity and low delay. In this paper, these schemes are extended either to scenarios with or without side information at the decoders to transmit multiple descriptions of a Gaussian source over independent parallel channels. They are based on a lattice scaling approach together with bandwidth reduction analog mappings adapted for this multiple description scenario. The rationale behind lattice scaling is to improve performance through bandwidth expansion. Another important contribution of this paper is the proof of the separation theorem for the communication …

Thermoeconomic diagnosis of air conditioning systems: experimental assessment of performance for improved reliability

2018

Thermoeconomic diagnosis is an exergy-based fault detection and diagnosis technique which has been recently extended to air conditioning systems. So far, developments of this technique have relied only on simulation data without being evaluated using real data. For the first time, this work aims at assessing the performance of thermoeconomic diagnosis using experimental data obtained from a five-ton packaged rooftop air conditioning unit (RTU) installed at Herrick Laboratories, Purdue University. The RTU was tested in psychrometric chambers under a wide range of operating conditions and fault levels. The following faults were investigated: (i) evaporator fouling, (ii) condenser fouling and …

QUEXME: A Query Expansion Method Applied to Water Information System

2009

The aim of the paper is to present and apply a QUery EXpansion MEthod called QUEXME while querying the Euro-Mediterranean Information System (EMWIS) on know-how in the Water sector. EMWIS provides a strategic tool for exchanging information and knowledge in the water sector between and within the Euro Mediterranean partnership countries (www.emwis.net). Information retrieval on the web or through some cooperation of information sources or some general knowledge bases is a complex process and a great challenge with the emergence of the semantic web. The aim of the query expansion method is to help and guide users to build their requests giving them some usually related terms close to their q…

Il lavoro etero-organizzato prima e dopo il caso Foodora Italia.

2019

l contributo ripropone la discussione sull’esegesi della fattispecie disciplinata dall’art. 1 comma 2 del d. lgs. n. 81 del 2015 (nel testo anteriore alla riforma del 2019) trattata dall’autore nei Colloqui Giuridici sul Lavoro del 2015 (a cura) di Antonio Vallebona per il Massimario di Giurisprudenza del Lavoro. Lo studio rigettava la tesi che il lavoro organizzato dal committente fosse la terza fattispecie e anzi con riferimento delle condizioni di applicazio­ne dimostrava la necessità di una lettura includente. La conclusione era che la nuova disciplina aveva natura antifraudolenta e determinava un allargamento (relativo) dell’area della subordi­nazione conseguente alla riduzione del cam…

This article republishes (after the Italian Supreme Court judgement n.166/2020 on the Foodora Italia case) the contribution to the exegesis of the case brought by art. 1 para­graph 2 of the d. lgs. n. 81 of 2015 (in the text before the 2019 reform) delivered by the author in the 2015's "Colloqui Giuridici sul Lavoro" (edited) by Antonio Vallebona for the "Massimario di Giurisprudenza del Lavoro". The study rejected the thesis that the job organ­ised by the client was an intermediate regulation between the employee and the self-employed ones. Indeed regarding the conditions for its application it showed the need for extensive reading. The conclusion was that the new discipline was (and is) an anti-fraudulent one. It led to a (relative) expansion of the area ofsubordination as a consequence of a reduction in the scope of coordinated self-employed work. A little more than four years after that article the Italian Supreme Court (with the judgement n.166/2020) on the Foodora Italia case addresses for the first time the issue of the hetero-organised work (by art. 1 paragraph 2 of the d. lgs. n. 81 of 2015). The Supreme Court fully adheres to the paper's thesis. So in terms of the "re­medial" function of the standardthe nature of the organisation's specific conditionand eventually reducing the legal frame for coordinated work. The fact that the procedural matter dealt with the riders was (then and now is) utterly irrelevant for the correct interpretation of such a new provision. Giving to riders of the employee status is not an effect of the peculiarit­ies of the work through digital platforms. It is a consequence of the remedial nature of such a case-law.
