ω-hypoelliptic differential operators of constant strength
2004
Abstract We study ω-hypoelliptic differential operators of constant strength. We show that any operator with constant strength and coefficients in E ω (Ω) which is homogeneous ω-hypoelliptic is also σ-hypoelliptic for any weight function σ=O(ω). We also present a sufficient condition in order to ensure that a differential operator admits a parametrix and, as a consequence, we obtain some conditions on the weights (ω,σ) to conclude that, for any operator P(x,D) with constant strength, the σ-hypoellipticity of the frozen operator P(x0,D) implies the ω-hypoellipticity of P(x,D). This requires the use of pseudodifferential operators.
Redox intermediates of plant and mammalian peroxidases: a comparative transient-kinetic study of their reactivity toward indole derivatives.
2002
Abstract A comparative study on the reactivity of five indole derivatives (tryptamine, N-acetyltryptamine, tryptophan, melatonin, and serotonin), with the redox intermediates compound I (k2) and compound II (k3) of the plant enzyme horseradish peroxidase (HRP) and the two mammalian enzymes lactoperoxidase (LPO) and myeloperoxidase (MPO), was performed using the sequential-mixing stopped-flow technique. The calculated bimolecular rate constants (k2, k3) revealed substantial differences regarding the oxidizability of the substrates by redox intermediates at pH 7.0 and 25°C. With HRP it was shown that k2 and k3 are mainly determined by the reduction potential (E°′) of the substrate with k2 bei…
Septal complex of the telencephalon of lizards: III. Efferent connections and general discussion.
1998
The projections of the septum of the lizard Podarcis hispanica (Lacertidae) were studied by combining retrograde and anterograde neuroanatomical tracing. The results confirm the classification of septal nuclei into three main divisions. The nuclei composing the central septal division (anterior, lateral, medial, dorsolateral, and ventrolateral nuclei) displayed differential projections to the basal telencephalon, preoptic and anterior hypothalamus, lateral hypothalamic area, dorsal hypothalamus, mammillary complex, dorsomedial anterior thalamus, ventral tegmental area, interpeduncular nucleus, raphe nucleus, torus semicircularis pars laminaris, reptilian A8 nucleus/ substantia nigra and cen…
À la recherche du Paradis Perdu. L’exil dans "Étoile errante" de J.M.G. Le Clézio
2017
J. M. G. Le Clézio, the author of the novel Wandering Star fitting into the sociopolitical context of the Israeli-Palestinian conflict, presents the story of two girls Esther and Nejma. Their life reflect the history of two nations: the Jews and the Palestinians. Sentenced to be exiled as a consequence of the war, they embark on a spiritual journey in time and space, in order to return to Paradise Lost. By becoming the witness of the enemy’s ruthlessness, unimaginable cruelty, they discover the importance of religion. It’s the way that they figure out who they are. The religion gives them a sense of security, hope and perseverance, by which, in the end, they return to the Promised Land. So …

Catacomba di Villagrazia di Carini. Il cubicolo X20. Ricerche 2008-2013
2014
Il X20 è uno dei cubicoli più rilevanti della galleria X. Consiste in una camera funeraria quadrangolare di m 8 (E-O) x 5 (N-S), preceduta da un dromos quadrato di m 1,80 x 1,80 e derivata da un preesistente arcosolio bisomo. La camera accoglie in tutto ventinove sepolture: dodici arcosoli sia per adulti che per bambini, una tomba a nicchia, due tombe a cassa e quattordici formae. I dati archeologici e gli esiti dell’analisi strutturale hanno permesso di accertare che l’attuale aspetto del cubicolo è il risultato di quattro fasi costruttive. Nella prima fase (IV.a) l’ambiente è a pianta quadrata (m 3,56 x 3,56), con arcosoli per bambini nel dromos e sulla parete nord; una decorazione ad aff…
The People Who Occupied The Fallen Angels' Chairs in Heaven: A Reiterated Idea in the Fifteenth Century, the Valencian Golden Age
2018
Johannes Ludovicus Vives (1493-1540) repeatedly used the symbolic image of humans occupying the fallen angels' chairs in heaven. In fact, the purpose of the creation of human beings seemed to be to occupy those empty chairs in paradise. This article focuses on the recurrent presence of that idea in the Valencian literature of the fifteenth century. It was a thought that was widely accepted even among people of a limited educational background. This paper supports the idea that Vives was the scholar who took this well-known belief from his homeland and introduced his Erasmian circle to it. That process of dissemination is described and explained by quoting some fragments of the most importan…
Mickiewiczowskie „miejsce” schronienia
2019
Figura miejsc schronienia – fundamentalna dla Mickiewiczowskiej wyobraźni – przewija się przez całą twórczość poety i przybiera różne kształty – od tradycyjnych domów-budowli, realnych siedzib, aż po niekonwencjonalne domy, jak metaforyczny „domek mego ducha” z Rozmowy wieczornej, czy domek-gniazdeczko usytuowany na liściu (liściach), o jakim mówi urywek lozański Uciec z duszą. Są jednak w życiu Mickiewicza wyjątkowe „momenty” rozpoznania eidosu Litwy, które generują jej oniryczne fantazmaty liryczne. Należą do nich: sytuacja zesłania oraz emigracji, perspektywa oddalenia oraz poczucia tęsknoty i straty konstytuuje w wyobraźni poety wzór, ideał wielopoziomowego uniwersum, tworząc przesycone…
Mythical Geographies
2018
This chapter explores the anthropological roots of Lost Paradise, which pivoted the expansion of Western civilization over centuries. tourism has evolved into many forms and practices that escape from water and fire, or the sand, but originally thermals were fertile grounds for the expansion and consolidation of modern tourism. This happens because of two main reasons, civilization whatever its origin symbolizes water as the most important resource for its production and expansion. Secondly, mythologies across cultures and times appeal to an “Eden” where water plays a crucial role as configurator of social order. For that reason, not surprisingly, in making tourism we need from reproaching …
L’elegia valenciana com a tòpic universal: la caiguda de València narrada des del Xarq al-Àndalus fins al romancer filipí
2016
Resum: Estudi de la formalització del concepte de València com a paradís perdut, des de la literatura àrab del Xarq al-Àndalus fins al romancer hispànic desenvolupat a l’arxipèlag filipí. S’hi analitza la conceptualització de l’elegia valenciana i el seu ús com a tòpic literari des de l’orient d’al-Àndalus fins a l’orient del món hispànic, explicant la formació del romancer filipí i la presència del Regne de València en les Lletres Filipines. S’hi estudien les elegies de la caiguda de la València islàmica a mans dels cristians, i com es formalitza una fascinació literària pel concepte de «València com a paradís», que s’exporta com a tòpic a una literatura asiàtica de base hispànica que té e…
