Normas para la realización de la bibliografía en Rev. Hispanoam. Hernia

2013

En Rev. Hispanoam. Hernia, el conjunto de las distintas referen- cias bibliográficas que compongan la bibliografía final de cada original se expresará mediante los Requisitos de uniformidad para el envío de originales a revistas biomédicas (más conocido como «normas de Vancouver»), normativa establecida y revi- sada por el icmje (International Committee of Medical Journal Editors, Comité Internacional de Directores de Revistas Médi- cas)1. Las normas Vancouver se han consolidado como una normativa internacional ampliamente aceptada y fácilmente inteligible, por lo que en Rev. Hispanoam. Hernia preferimos y recomendamos este modelo de citación de la bibliografía, a pesar de que es una normat…

Donne, corpi e territori: riflessioni sulla transitorietà

2023

Questo intervento analizza la transitorietà come concetto pregnante nella geografia di genere attraverso l’interpretazione di due video. Nel primo, la transitorietà è legata sia alla velocità del movimento del corpo nello spazio, sia al ritmo. Per Lefebvre, i ritmi sono costituiti dalla relazione fra luoghi, corpi in movimento e tempo. Il corpo e lo spazio hanno un loro ritmo, e quando nell’interazione reciproca questi due ritmi si incontrano, entrano “in armonia (euritmia) o in contrasto (aritmia) tra loro” (Lefebvre 1991). Lo stato di aritmia dipende dalle rappresentazioni associate al movimento: la dimensione politica del corpo e le gerarchie della classe, del genere, della razza. L’arit…

Sguardi di genere nel Sud Africa post-apartheid. Zanele Muholi e le immagini del mancante

2017

In June 2013 Palermo held the National Gay Pride. The opening of the manifestation was the solo photographic exhibition of Zanele Muholi. 25 photos of Being (2007), 21 of Faces & Phases (2009) and Caitilin and I (2009) are the corpus that this article wants to examine inside the main event of Palermo’s Gay Pride. The paper presents how Muholi’s works overturn the act of seeing by representing the image of the missing: exhibits how the invisible lesbian body problematized the local and national South African space (and not only that); it shows how the spatial exclusion of the not-disciplined bodies make visible the divisions of the spatial and gendered relations. The long story of the wo…

Synthesis, X-ray Structure, Conformational Analysis, and DFT Studies of a Giant s-Triazine bis-Schiff Base

2021

The current work involves the synthesis of 2,2′-(6-(piperidin-1-yl)-1,3,5-triazine-2,4-diyl)bis(hydrazin-2-yl-1-ylidene))bis(methanylylidene))diphenol 4, characterization, and the DFT studies of the reported compound. The crystal unit cell parameters of 4 are a = 8.1139(2) Å, b = 11.2637(2) Å, c = 45.7836(8) Å. The unit cell volume is 4184.28(15) Å3 and Z = 4. It crystallized in the orthorhombic crystal system and Pbca space group. The O…H, N…H, C…H, H…H and C…C intermolecular contacts which affect the crystal stability were quantitatively analyzed using Hirshfeld calculations. Their percentages were calculated to be 9.8, 15.8, 23.7, 46.4, and 1.6% from the whole contacts occurred in the cr…

Synthesis and X-ray Crystal Structure of New Substituted 3-4′-Bipyrazole Derivatives. Hirshfeld Analysis, DFT and NBO Studies

2021

A new compounds named 3-4′-bipyrazoles 2 and 3 were synthesized in high chemical yield from a reaction of pyran-2,4-diketone 1 with aryl hydrazines under thermal conditions in MeOH. Compound 2 was unambiguously confirmed by single-crystal X-ray analysis. It crystalizes in a triclinic crystal system and space group P-1. Its crystal structure was found to be in good agreement with the spectral characterizations. With the aid of Hirshfeld calculations, the H…H (54.8–55.3%) and H…C (28.3–29.2%) intermolecular contacts are the most dominant, while the O…H (5.8–6.5%), N…H (3.8–4.6%) and C…C (3.0–4.9%) are less dominant. The compound has a polar nature with a net dipole moment of 6.388 Debye. The …

'A Mourning Rome, A Dangerous Rome': Theatricality and Anti-Theatricality in Two Julius Caesar Films

2020

Este ensayo estudia la 'teatralidad' y la 'antiteatralidad' en dos versiones cinematográficas del Julio César de William Shakespeare : Julio César (dir. Gregory Doran, 2012) y yo, Cinna.(el poeta) (dir. Tim Crouch, 2012). Las puestas en escena originales de las películas han sido analizadas como ejemplos de Shakespeares poscoloniales y en relación con su relevancia durante los Juegos Olímpicos de 2012. Sin embargo, como películas, pueden estudiarse como adaptaciones conectadas a las luchas socioeconómicas y políticas que tienen lugar en el ámbito local. contexto. Estoy usando la distinción de Martin Puchner de 'teatralidad' y 'antiteatralidad'. Mientras que el primero celebra la actuación p…

La representación de la dictadura en el cine de animación argentino

2019

Las imágenes cinematográficas permiten la construcción colectiva de la memoria. La representación del desaparecido es un reto para el cine documental que afronta esta problemática en la reconstrucción de la memoria traumática. El objetivo de este trabajo es analizar las características de la animación utilizadas en la producción audiovisual argentina para abordar la dictadura de la Junta Militar. El corpus está compuesto por nueve obras que incorporan total o parcialmente la animación como estrategia de representación: Los rubios (Albertina Carri, 2003), El Tiempo y la Sangre (Alejandra Almirón, 2004), La Matanza (María Giuffra, 2005), Padre (Santiago Grasso, 2008), Infancia clandestina (Be…

Petrography and high-resolution geochemical records of Lower Jurassic manganese-rich deposits from Monte Mangart, Julian Alps

2016

Deposits with unusually high Mn contents sampled at Monte Mangart in the Julian Alps include organic-rich marlstone and black shale with interbedded manganoan and siliceous limestone, which were deposited during the early Toarcian Oceanic Anoxic Event. Mn enrichment during that period has been related to global sea-level change coincident with increasing subsidence rate. The formation of Fe-Mn nodules, marking a hardground at the base of the Monte Mangart section, seems to be triggered by release of Mn from remote hydrothermal vents into a region of relatively elevated submarine topography where oxidizing conditions prevailed. However, very high Mn contents in carbonate phases above the har…

Tensor tomography in periodic slabs

2018

Abstract The X-ray transform on the periodic slab [ 0 , 1 ] × T n , n ≥ 0 , has a non-trivial kernel due to the symmetry of the manifold and presence of trapped geodesics. For tensor fields gauge freedom increases the kernel further, and the X-ray transform is not solenoidally injective unless n = 0 . We characterize the kernel of the geodesic X-ray transform for L 2 -regular m -tensors for any m ≥ 0 . The characterization extends to more general manifolds, twisted slabs, including the Mobius strip as the simplest example.

An integrated geodetic and InSAR technique for the monitoring and detection of active faulting in southwestern Sicily

2020

We present the results of the analysis of GNSS (Global Navigation Satellite System) and InSAR (Interferometric synthetic-aperture radar) data collected in the frame of a project financed by the “Struttura Terremoti” of INGV (Istituto Nazionale di Geofisica e Vulcanologia). Combined investigations pointed out for potential seismogenic sources for destructive earthquakes recorded in southwestern Sicily, including the 1968 Belice earthquake sequence and that supposed to have destroyed the Greek city of Selinunte which, according to geoarcheological data experienced two earthquakes in historical times. Our approach is aimed to evaluate the current deformation rate in SW Sicily and to improve th…
