Adiabatic regularization with a Yukawa interaction

2017

We extend the adiabatic regularization method for an expanding universe to include the Yukawa interaction between quantized Dirac fermions and a homogeneous background scalar field. We give explicit expressions for the renormalized expectation values of the stress-energy tensor $\langle T_{\mu\nu} \rangle$ and the bilinear $\langle \bar\psi\psi\rangle$ in a spatially flat FLRW spacetime. These are basic ingredients in the semiclassical field equations of fermionic matter in curved spacetime interacting with a background scalar field. The ultraviolet subtracting terms of the adiabatic regularization can be naturally interpreted as coming from appropriate counterterms of the background fields…

Probing the creatable character of some significant universe models

2008

An unambiguous physical definition of creatable universes was recently proposed. According to it, flat and closed Friedmann-Robertson-Walker (FRW) backgrounds can be created as quantum vacuum fluctuations, whereas open backgrounds are not creatable. Here, physically motivated perturbations of closed and flat backgrounds are analyzed. Various creatable perturbed FRW universes are thus found. Some of them involve scalar and tensor perturbations with appropriate spectra, whereas other ones are Bianchi models.

Kehollisuuden ulottuvuudet Lauri Rauhalan holistisessa ihmiskäsityksessä - esimerkkinä addiktio

2020

Puhuessamme ihmisen kehosta tai ruumiista ei aina ole selvää, mitä itse asiassa tarkoitamme. Lauri Rauhalan holistiseen ihmiskäsitykseen kuuluvaa kehollisuuden olemispuolta on aiemmin tarkasteltu ainoastaan aineellis-orgaanisena tapahtumisena. Holistisessa kontekstissaan kehollisuus näyttäytyy kuitenkin myös persoonan elettynä kehona. Artikkeli tarjoaa filosofisen ja holistisen näkökulman addiktiokeskusteluun vallitsevan biomedikaalisen sairausoletuksen sijaan. Myös holistisessa psykoterapiassa addiktoitunut yksilö tulisi kohdata addiktiotaan elämäntilanteessaan kehollisesti kokevana ja ilmaisevana persoonana. peerReviewed

Scrivere del Mezzogiorno.Processi di auto-orientalism nella Letteratura italiana

2014

Questo lavoro guarda al contributo che la letteratura italiana ha dato relativamente alla costruzione e alla sedimentazione, nell'immaginario comune e nella percezione pubblica, dell'identità geografica e culturale del Mezzogiorno, ovvero di quella «consapevolezza geopolitica» di cui parlava Edward Said a proposito di altre aree del globo. Per fare ciò, sono stati identificati e presi in esame due diversi momenti che nella storia d'Italia si sono contraddistinti per una forte ridiscussione dell'immagine delle regioni meridionali del paese. I decenni immediatamente successivi all'Unità, infatti, sono stati caratterizzati da ampi dibattiti in merito al ruolo che il Sud doveva avere all'intern…

Cuando digo futuro. Imaginario del desarrollo, cultura y anti-intelectualismo en Cuba

2012

A partir del análisis de canciones de Silvio Rodríguez y el Grupo de Experimentación, así como de otros textos culturales de los primeros años del periodo revolucionario en Cuba, se muestra cómo la articulación del imaginario del desarrollo en los discursos revolucionarios cubanos iría de la mano de una reformulación profunda del rol de la cultura en la sociedad revolucionaria y de una tematización crítica de la función de los intelectuales en ella. En ese sentido, y como se verá, la inclusión del léxico, la iconografía y buena parte de la sintaxis de los lenguajes del desarrollo en el pensamiento revolucionario cubano no estuvo desvinculada del crecimiento y la consolidación de lo que se h…

First description of non-motile Yersinia ruckeri serovar I strains causing disease in rainbow trout, Oncorhynchus mykiss (Walbaum), cultured in Spain.

2006

Yersinia ruckeri, the causal agent of enteric redmouth (ERM) disease, was isolated from epizootics that occurred in different Spanish rainbow trout, Oncorhynchus mykiss (Walbaum), farms in which vaccination against ERM had been performed. In all episodes, the most pronounced clinical signs exhibited by affected fish were severe haemorrhages in the mouth, eyes and around the vent. The isolates were identified as Y. ruckeri serovar I by 16S rRNA sequencing together with serological tests. They lacked motility and lipase activity and thus belonged to biotype 2, and were highly virulent for juvenile rainbow trout, both by intraperitoneal injection (from 3.1 x 10(2) to 6.3 x 10(3) cfu per fish) …

SURFACE ROUGHNESS PREDICTION OF ELECTRO-DISCHARGE MACHINED COMPONENTS USING ARTIFICIAL NEURAL NETWORKS

2016

Electro-Discharge machining (EDM) is a thermal process comprising a complex metal removal mechanism, which involves the formation of a plasma channel between the tool and the workpiece electrodes leading to the melting and evaporation of the material to be removed. EDM is considered especially suitable for machining complex contours with high accuracy, as well as for materials that are not amenable to conventional removal methods. However, several phenomena negatively affecting the surface integrity of EDMed workpieces need to be taken into account and studied in order to achieve the optimization of the process. Recently, artificial neural networks (ANN) have emerged as a novel modeling tec…

DIO SALVI IL RESTAURO. L’apporto inglese alla cultura della conservazione dei monumenti

2020

Sebbene già riuscissimo a percepire quanto rilevante fosse l’apporto inglese per aver contribuito alla definizione del restauro modernamente inteso, sino ad oggi mancavano ancora sia una chiara visione d’insieme delle articolate vicende connesse all'affermazione dei princìpi conservativi, sia una più approfondita conoscenza delle fonti documentarie, necessarie al fine di tracciare i profili culturali dei protagonisti e scandagliarne i contributi teorici. La ricostruzione delle vicende è sviluppata entro margini temporali estesi all'incirca per tre secoli, dalla fine del Seicento al principio del Nove-cento, e strutturata attraverso la traduzione e lo studio di testi perlopiù mai circolati i…
