Dyes of a Shadow Theatre: Investigating Tholu Bommalu Indian Puppets through a Highly Sensitive Multi-Spectroscopic Approach
2021
Tholu Bommalu are typical leather puppets of the traditional Indian shadow theatre. Two of these objects are part of a collection in the International Puppets Museum “Antonio Pasqualino” (Palermo, Sicily, Italy), which can count on one hundred-seventy-three of artifacts. These Indian puppets were investigated to obtain information related to the use of dyes for their manufacturing through a multi-technical approach exploiting the combination of highly sensitive spectroscopic techniques. Wet cotton stubbons were used to entrap small particles of dyes on the fibers from the art objects for the consequent analyses. Visible Light Micro-Reflectance spectroscopy was employed for the preliminary i…
JIMWLK and beyond: From concepts to observables
2016
Volume: 112 Host publication title: 6th International Conference on Physics Opportunities at an Electron-Ion Collider The Color Glass Condensate and its associated evolution equation, the JIMWLK equation have applications to many observables far beyond totally inclusive observables. The phenomenology is so rich that little has been done to explore beyond scaling behavior of correlators. We show first examples that exemplify the considerations necessary to access additional information both experimentally and theoretically and demonstrate that the Wilson line correlators appearing throughout make it imperative to consistently take into account that one is dealing with correlators of group el…
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
Thermo-Mechanical Behaviour of Flax-Fibre Reinforced Epoxy Laminates for Industrial Applications
2015
The present work describes the experimental mechanical characterisation of a natural flax fibre reinforced epoxy polymer composite. A commercial plain woven quasi-unidirectional flax fabric with spun-twisted yarns is employed in particular, as well as unidirectional composite panels manufactured with three techniques: hand-lay-up, vacuum bagging and resin infusion. The stiffness and strength behaviours are investigated under both monotonic and low-cycle fatigue loadings. The analysed material has, in particular, shown a typical bilinear behaviour under pure traction, with a knee yield point occurring at a rather low stress value, after which the material tensile stiffness is significantly r…
The Formalisation of Water Use and Conditional Ownership in Colca Valley, Peru
2019
This article discusses the production and negotiation of water ownership among peasant farmers in the Majes-Colca watershed in southern Peru, where the public water administration initiated a process of formalising user rights for potable water in 2011. While a large-scale irrigation project channels water from the headwaters to export-oriented agriculture in the desert, the supply of water is getting scarcer because of climate change. The Peruvian water resources law from 2009 acknowledges water as public property, yet emphasises its economic value and encourages private investment. The farmers in the highlands see water not only as a resource but also as a lifegiving force provided by the…
Pressure-Dependent Tuning of Photoluminescence and Size Distribution of Carbon Nanodots for Theranostic Anticancer Applications
2020
Carbon nanodots (CDs) have recently attracted attention in the field of nanomedicine because of the biocompatibility, cost-effective nature, high specific surface, good near infrared (NIR) photothermal conversion into heat and tunable fluorescence properties, which have paved the way toward incorporating use of CDs into innovative anticancer theranostic platforms. However, a reliable synthesis of CDs with established and controlled physiochemical proprieties is precluded owing to the lack of full manipulation of thermodynamic parameters during the synthesis, thus limiting their use in real world medical applications. Herein, we developed a robust solvothermal protocol which allow fine contr…
MTOR inhibitor-based combination therapies for pancreatic cancer
2018
Background: Although the mechanistic target of rapamycin (MTOR) kinase, included in the mTORC1 and mTORC2 signalling hubs, has been demonstrated to be active in a significant fraction of patients with pancreatic ductal adenocarcinoma (PDAC), the value of the kinase as a therapeutic target needs further clarification. Methods: We used Mtor floxed mice to analyse the function of the kinase in context of the pancreas at the genetic level. Using a dual-recombinase system, which is based on the flippase-FRT (Flp-FRT) and Cre-loxP recombination technologies, we generated a novel cellular model, allowing the genetic analysis of MTOR functions in tumour maintenance. Cross-species validation and pha…
Les poisons du XIXe et leur traduction à l’espagnol : Mateu Orfila et son Traité des poisons (1814-1815)
2019
Dans ce travail, on étudie une des œuvres pionnières de référence en toxicologie du XIXe siècle : Traité des poisons, publiée par Mathieu Orfila entre 1814 et1815 à Paris, traduite en espagnol par le Dr. Mariano de Larra y Langelot en 1819, et éditée à Madrid. Larra se vante, dans l'introduction, que sa traduction a été révisée par Orfila lui-même, détail qui n’apparaît pas dans les traductions en allemand, anglais ou italien. Nous présenterons les événements historiques qui ont accompagné cette première traduction, ainsi que les raisons qui ont conduit Mariano de Larra, père du célèbre écrivain romantique Mariano José de Larra, à traduire ce travail après avoir été exilé en France pendant …
Le graphic novel italien Peppino Impastato un giullare contro la mafia et sa traduction française
2018
Eddie Campbell dans son Graphic Novel Manifesto définit ce nouvel art «a movement rather than a form», un courant d’auteurs dont le but est d’élever la bande dessinée à des niveaux plus ambitieux, d’autant plus que l’objet de leurs œuvres dérive de l’histoire passée où récente d’un Pays. Le critique et essayiste italien Goffredo Fofi considère le graphic novel la forme expressive la plus vitale au monde aujourd’hui au même niveau que les documentaires cinématographiques. Traduire un graphic novel comporte tous les défis de la traduction d’une bande dessinée et d’un récit avec en plus, dans le cas de Peppino Impastato, la difficulté linguistique due à l’emploi de formes dialectales du sicili…
