A note on the rational canonical form of an endomorphism of a vector space of finite dimension

2018

[EN] In this note, we give an easy algorithm to construct the rational canonical form of a square matrix or an endomorphism h of a finite dimensional vector space which does not depend on either the structure theorem for finitely generated modules over principal ideal domains or matrices over the polynomial ring. The algorithm is based on the construction of an element whose minimum polynomial coincides with the minimum polynomial of the endomorphism and on the fact that the h-invariant subspace generated by such an element admits an h-invariant complement. It is also shown that this element can be easily obtained without the factorisation of a polynomial as a product of irreducible polynom…

Inuentiones y translationes de S. Mercurio

2019

Inuentiones and translationes of the relics are part of the hagiographic dossier of a saint and provide interesting information about his cult over the centuries. For S. Mercurius of Caesarea the original texts in Greek have been lost, but we have two collections miracles in Coptic that narrate the inuentio and translatio of his relics and there is also a medieval tradition about his translatio to Benevento (Italy). From all these texts is deduced a healing cult of S. Mercurius based on the usual topics.

Geographical variation in wing polymorphism of the waterstrider Aquarius najas (Heteroptera, Gerridae)

1999

The waterstrider Aquarius najas is wingless in Northern Europe, while winged individuals occur frequently in Central and Southern Europe. To test if the latitudinal difference is genetically controlled, we collected mature individuals from 10 different populations and raised their offspring in ‘common garden’ laboratory conditions. Half of these populations were from southern and the other half from central Finland. Daylength and temperature do influence wing development among other species of waterstriders, and thus we maintained a similar short daylength and warm conditions for all populations. These conditions should be favourable for wing development in general. Among laboratory-bred in…

Strategie progettuali e questioni di architettura

2009

L’articolo riflette sul significato dei seminari di progettazione svolti negli ultimi anni in Sicilia ( Marsala, Menfi, Cinisi, S.Agata di Militello) notevoli sono stati i risultati attraverso la messa a punto di una didattica diversa dalla pratica dei laboratori universitari. La riflessione sulla strategia progettuale e le questioni di architettura sono state alla base delle elaborazioni progettuali svolte da studenti e tutors con il contributo di docenti di fama internazionale.

Vicende edilizie, usi e progetti per l'Arsenale tra Settecento e Ottocento

2017

Pur nella sostanziale immutabilità dell’impianto seicentesco progettato da Mariano Smiriglio e del suo aspetto configurativo complessivo, l’Arsenale di Palermo fu oggetto nel corso della sua esistenza di continui interventi edilizi dettati sia dall’esigenza di una costante manutenzione della fabbrica architettonica di notevole dimensione, sia da interventi di consolidamento strutturale in conseguenza dei danni arrecati dai terremoti che colpivano periodicamente Palermo, sia, infine, dalla necessità di adattare l’edificio, anche per brevi periodi, a diversi usi. È nota l’utilizzazione a carcere dell’Arsenale, più precisamente, come riportato dal marchese di Villabianca, a «serraglio ordinari…

Breeding success of a colony of Boat-billed Herons Cochlearius cochlearius (Ciconiiformes: Ardeidae) in pasturelands of Costa Rica

2014

The breeding success of a double-brooding colony of Boat-billed Herons Cochlearius cochlearius was studied in pasturelands of Costa Rica. Mean clutch size in the first clutches (2.9 eggs/nest) was higher than in second and repeat clutches (2.3 eggs/nest). Breeding success was similar in the first attempt and second attempts(20.7 % and 21.7 %, respectively). In both attempts earlier nests enjoyed a higher breeding success. Starvation of the youngest chicks within the nest and destruction of nests by bad weather conditions were the main factors related to nestling death. No effects of human activity on the reproduction of the breeding colony were observed. Rev. Biol. Trop. 54 (4): 1131-1134. …

Detection of Intrinsic Source Structure at ~3 Schwarzschild Radii with Millimeter-VLBI Observations of SAGITTARIUS A*

2018

We report results from very long baseline interferometric (VLBI) observations of the supermassive black hole in the Galactic center, Sgr A*, at 1.3 mm (230 GHz). The observations were performed in 2013 March using six VLBI stations in Hawaii, California, Arizona, and Chile. Compared to earlier observations, the addition of the APEX telescope in Chile almost doubles the longest baseline length in the array, provides additional {\it uv} coverage in the N-S direction, and leads to a spatial resolution of $\sim$30 $\mu$as ($\sim$3 Schwarzschild radii) for Sgr A*. The source is detected even at the longest baselines with visibility amplitudes of $\sim$4-13% of the total flux density. We argue th…

Aspetti tecnologici per il riuso: contributi al dibattito

2016

Qui il taglio della trattazione sul riuso della Centrale Enel Tifeo è legato alle questioni tecnologiche sia pure in un’accezione ampia che declina sia le tecniche ambientali che le tecnologie connesse agli edifici e alle costruzioni. Una lettura disciplinare, certamente parziale e limitata, che non vuole mancare però di individuare fattori comuni e temi di dibattito di più ampio respiro. Si tenta questa analisi con una struttura di tre paragrafi, parzialmente correlati a scale di problemi: il contesto e il lotto, quale area di dominio; l’involucro, soprattutto considerato per l’edificio dei turbo-alternatori; l’ambiente indoor e gli spazi interni in edifici dalla spazialità estremamente pa…

Analisi biomolecolare di ceppi di Canine Distemper Virus (CDV) in furetti domestici (Mustela putorius furo)

2011

L’agente eziologico del cimurro (CDV) appartiene alla famiglia Paramyxoviridae, genere Morbillivirus ed è causa di una patologia infettiva e contagiosa in canidi, mustelidi e procionidi. Gli Autori, descrivono un caso clinico di cimurro in due furetti domestici vaccinati con un ceppo Onderstepoort avianizzato. e la caratterizzazione biomolecolare del CDV isolato. I furetti presentavano un quadro clinico caratterizzato da dermatite pruriginosa e squamo-purulenta, alla regione del mento, peri-labiale, peri-vulvare ed al condotto uditivo esterno. I soggetti venivano a morte tre settimane dopo l’esordio dei sintomi. I campioni di croste prelevati sono stati sottoposti ad estrazione degli acidi …
