Endovascular treatment of abdominal aortic anastomotic pseudoaneurysm. The experience of two centers.
2012
INTRODUCTION: Abdominal aortic pseudoaneurysms are a rare but serious complication of aortic surgery. Treatment with traditional open surgery is associated with a high rate of perioperative mortality and morbidity. Endovascular treatment is less invasive and guarantees lower mortality and morbidity rates. The aim of this study was to evaluate the role of short-, medium- and long-term endovascular treatment of these pseudoaneurysms. MATERIALS AND METHODS: Over the past 10 years, 14 patients with abdominal aortic aneurysms, which developed after prior aortic surgery, underwent endovascular treatment involving implantation of an endoprosthesis at our institutions. Exclusion criteria were emerg…
Performance cognitive in pazienti anziani sottoposti a endoarterectomia o a stenting carotideo: Studio di follow up a 12 mesi
2010
Introduction. In this study we investigated short and long-term impact of carotid endarterectomy (CEA) and carotid artery stenting (CAS) in cognitively healthy elderly subjects with severe carotid stenosis on several cognitive functions by neuropsychological evaluation before surgery and after three and twelve months. Methods. Cognition, mood and functional status were evaluated in 28 patients undergoing CEA (24 M, 4 F, 72.6 ± 5.8 years old) and in 29 patients undergoing CAS (17 M, 12 F, 75.1 ± 5.7 years old) by a broad spectrum of tests assessing mood, functional status, memory, attention, verbal fluency, visuospatial and constructional abilities. Results. No significant differences in s…
Shock control bump design optimization on natural laminar aerofoil
2011
The chapter investigates Shock Control Bumps (SCB) on a Natural Laminar Flow (NLF) aerofoil; RAE 5243 for Active Flow Control (AFC). A SCB approach is used to decelerate supersonic flow on the suction/pressure sides of transonic aerofoil that leads delaying shock occurrence or weakening of shock strength. Such an AFC technique reduces significantly the total drag at transonic speeds. This chapter considers the SCB shape design optimisation at two boundary layer transition positions (0 and 45%) using an Euler software coupled with viscous boundary layer effects and robust Evolutionary Algorithms (EAs). The optimisation method is based on a canonical Evolution Strategy (ES) algorithm and inco…
Confined subgroups in periodic simple finitary linear groups
2002
A subgroupX of the locally finite groupG is said to beconfined, if there exists a finite subgroupF≤G such thatX g∩F≠1 for allg∈G. Since there seems to be a certain correspondence between proper confined subgroups inG and non-trivial ideals in the complex group algebra ℂG, we determine the confined subgroups of periodic simple finitary linear groups in this paper.
AMBIENTE E TUTELA INDIVIDUALE INTERGENERAZIONALE
2020
Il saggio propone una riflessione sulla possibilità di una tutela ambientale individuale ed intergenerazionle, muovendo da una ricostruzione del concetto di ambiente nella prospettiva esistenzialista, segnata dal tessuto valoriale costituzionale interno ed europeo e dall’affermazione del principio dello sviluppo sostenibile. La valorizzazione dell’ambiente nella teoria dei beni trova nel dibattito sui beni comuni nuovi orizzonti di senso, coniugando la prospettiva esistenzialista del danno ambientale con quella propria della teorica dei beni comuni. All’esito di tale percorso ricostruttivo, avvalorato dalle recenti pronunce della Corte europea, l’autore giunge a fondare una legittimazione i…
Appearance as the Arrival of the Future
2017
AMBIGUITIES of language often indicate a problematic subject matter. That is the case with the word "appear" (erscheinen). When I say that an acquaintance (or someone with whom I was previously unacquainted) "appeared" to me, in order to speak with me, the meaning is: he came to me, he showed up in my habitat, perhaps at my home. He did not only seem (scheinen) to be there; he really was there. When something appears to us, it does not only seem to be with us, it actually is present. Appearance and existence are here very closely connected. But on the other hand, my acquaintance still exists even when he does not appear to me. Whether that would still be true if he appeared nowhere whether …

Endovascular Management, with the Use of Solitaire Stent as the First-Line Treatment for Cerebral Vasculitis: A Case Report
2019
Cerebral vasculitis that comprises a group of noninfectious inflammatory vasculitides, can produce a variety of neurologic events, including also life-threatening ones. In this paper we describe the case report of a 37-year-old female patient with cerebral vasculitis manifesting as ischemic stroke of the left cerebral hemisphere. Her clinical status deteriorated, despite immunosuppression. CT angiography demonstrated several occlusions of intracranial arteries. We describe details of endovascular revascularization of intracranial arteries in this patient, with focus at the use of the Solitaire stent, which seems to be particularly useful in such challenging cases. After endovascular repair …
Solution of the Skyrme-Hartree–Fock–Bogolyubovequations in the Cartesian deformed harmonic-oscillator basis. (VIII) hfodd (v2.73y): A new version of …
2017
We describe the new version (v2.73y) of the code HFODD which solves the nuclear Skyrme Hartree-Fock or Skyrme Hartree-Fock-Bogolyubov problem by using the Cartesian deformed harmonic-oscillator basis. In the new version, we have implemented the following new features: (i) full proton-neutron mixing in the particle-hole channel for Skyrme functionals, (ii) the Gogny force in both particle-hole and particle-particle channels, (iii) linear multi-constraint method at finite temperature, (iv) fission toolkit including the constraint on the number of particles in the neck between two fragments, calculation of the interaction energy between fragments, and calculation of the nuclear and Coulomb ene…
Between Life and Existence. Heidegger’s Aristotelianism and the Question of Animality
2021
This paper starts by investigating the Aristotelian roots of Heidegger’s stance toward animal life from 1924 lecture course “Basic concepts of Aristotelian philosophy” to 1929/30 lecture course “The fundamental concepts of Metaphysics”. In following Aristotle, Heidegger displays the ontological transition from life to existence as grounded to the peculiar linguistic ability of human beings. In doing that, both Heidegger and Aristotle seem to establish a connection between an existential faculty (logos) and the apparently dominant position occupied by our species. On the other side, though, to be endowed with logos means for human beings to be able to de-centre themselves in recognizing the …
