L’art et l’histoire de l’art à l’ère d’Internet et de Photoshop
En se transformant et pour ainsi dire en se dématérialisant, les médias sont devenus si puissants et imposants qu’ils nous entraînent dans un réseau d’ubiquité et d’interaction qui a multiplié notre accès à tous types d’information. Mais comme toutes les grandes mutations déterminées par le progrès technologique, la révolution électronique se présente elle aussi comme une médaille à deux faces : d’un côté elle nous offre une quantité indéniable d’avantages dont on ne peut déjà plus se passer,..
Pourquoi l’histoire de l’art suisse intéresse-t-elle ?
Antonio Pinelli. Tu as enseigné pendant quinze ans à l’Université de Lausanne dans les années 1960-1970, ce qui te procure un regard à la fois intérieur et extérieur, impliqué et détaché, et fait de toi un interlocuteur privilégié en matière d’art et d’histoire de l’art suisse. En outre, un des thèmes les plus stimulants de ta recherche s’articule autour des Alpes non plus vues comme une barrière infranchissable mais comme une frontière perméable et un carrefour culturel dans lequel la Suisse..
No centro do segredo : Mýthos e lógos em primeiras estórias
Orientador : ProfÂŞ. DrÂŞ. PatrĂcia da Silva CardosoDissertação (mestrado) - Universidade Federal do Paraná, Setor de CiĂŞncias Humanas, Programa de PĂłs-Graduação em Letras. Defesa: Curitiba, 31/03/2016Inclui referĂŞncias : f. 116-121Resumo: Amparado em Antonio Candido e Eduardo Coutinho, a presente pesquisa tem por objetivo investigar o estatuto do pensamento lĂłgico e do pensamento mĂtico na obra de 1962, Primeiras estĂłrias, de JoĂŁo GuimarĂŁes Rosa. Com efeito, em uma abordagem imanente das narrativas rosianas, e a partir do diálogo mais detido com estes dois comentadores e com outros pesquisadores mais recentes da fortuna crĂtica, construĂmos o que denominamos sistema composicional dos princĂpios antitĂ©ticos da obra. Esse sistema consiste em uma representação do que entendemos como o processo criativo do volume. Em verdade, esta matriz formal que articula dialeticamente os dois princĂpios do nosso sistema pode ser reconhecida em todas as narrativas do volume e em todos os nĂveis de análise. Deste modo, por meio do tensionamento entre o MĂ˝thos e o LĂłgos, Primeiras estĂłrias pode ser erigida a condição de poesia narrativa, ou prosoema, pois embaralha os gĂŞneros da poesia e da prosa em estĂłrias que atualizam o mĂtico e arcaĂzam o lĂłgico, em um processo quĂmico de criação. Assim, oralidade, primitivismo, coletividade e o pensamento metafĂsico-sobrenatural, prĂłprios do princĂpio mĂtico, estĂŁo dialeticamente articulados com o individualismo, com o modernismo, o escrito e o pensamento fĂsico-natural, pressupostos do princĂpio lĂłgico. E a partir dessa dupla raiz composicional Ă© possĂvel reconhecer a unidade do volume, em seu barroquismo linguĂstico e na sua estrutura especular. Pois a narrativa medial de Primeiras estĂłrias, O espelho, reflete esse sistema composicional dos princĂpios antitĂ©ticos linguisticamente e articula toda a obra simetricamente, Ă medida que sua unidade implica a duplicidade do MĂ˝thos e LĂłgos enquanto palavra.Abstract: Supported by Antonio Candido and Eduardo Coutinho, the present study aims to investigate the status of logical thinking and mythical thought in the work of 1962 Primeiras estĂłrias, by JoĂŁo GuimarĂŁes Rosa. Indeed, in an immanent approach to Rosa's narrative, and from closer dialogue with these two commentators and other more recent researchers of literary criticism, we built what we call compositional system of antithetical principles of work. This system consists of a representation of what we understand as the creative process of the volume. In fact, this formal matrix that articulates dialectically the two principles of our system can be recognized in all the volume of narratives and in all levels of analysis. Thus, through the tensioning between the MĂ˝thos and LĂłgos, Primeiras estĂłrias can be erected condition of narrative poetry, or prosoema, as it scrambles genres of poetry and prose in stories that update the mythical and antiquated the logical, in a chemical process of creation. So orality, primitivism, community and the metaphysical-supernatural thinking, own the mythical principle, are dialectically articulated with individualism, with modernism, written and physical-natural thinking, prerequisites for the logical principle. And from this double root compositional it is possible to recognize the volume’s the unit in his baroque language and its structure speculate. Because the medial narrative of Primeiras estĂłrias, O espelho, reflects these compositional system antithetical principles linguistically and articulates all the work symmetrically, as its unity implies the duplicity of the Word, designed as MĂ˝thos and LĂłgos
Autophagy and apoptosis: studies on the effects of bisthiosemicarbazone copper(II) complexes on p53 and p53-null tumour cell lines
A comparative study between two bisthiosemicarbazones, 2,3-butanedione bis(4,4-dimethyl-3-thiosemicarbazone) and 2,3-butanedione bis(2-methyl-3-thiosemicarbazone), and their copper(II) complexes is reported. The four compounds have been tested on leukemia cell line U937 and on adenocarcinoma cell line A549. The study includes cell viability, cell cycle, morphological changes, assessment of apoptosis, analysis of autophagy, measurement of reactive oxygen species (ROS) and of lipid peroxidation, protein determination, assessment of the expression of p53 and cellular uptake of metal complexes. Tests about the copper uptake under normoxic and hypoxic conditions were also carried out on solid tumour cell line A549. The four compounds under study elicit different effects on the two lines adopted as representatives of p53 and p53-null cells. The role of the metal is relevant and it is likely that the metal-mediated oxidative stress plays an essential role in the whole process. The mechanisms induced by these molecules differ not only as a function of cell line but also of dose. The responses include two distinct self-destructive processes, autophagy and apoptosis

Le portrait du roi : entre art, histoire, anthropologie et sémiologie
Dans la théorie des arts à l’époque moderne, le portrait du roi a un statut singulier : en tant que portrait, il dépend du dictat de la ressemblance au modèle naturel, qui l’éloigne de la noble quête de l’idéal, mais en tant que représentation du souverain, donc d’un personnage hors norme à la perfection incomparable, il a vocation d’être un chef-d’œuvre. De ce fait, le portrait du roi échappe, du moins dans la littérature encomiastique, au discrédit qui frappe progressivement le genre du por..
EXPERIMENTAL AND NUMERICAL ASSESSMENT OF A LAST STAGE ST BLADE DAMPING AT LOW LOAD OPERATION
As LP steam turbines are requested to work at strong part-loads, LSB stalled and unstalled flutter may occur. Testing on a downscaled steam turbine in T10MW test plant have been carried out to measure LSB aggregated damping at low load. Also numerical analysis to predict aerodynamic damping have been performed and results have been compared to experimental data, allowing software tool validation at low load
Verso le elezioni politiche 2023: Rosatellum o nuova legge elettorale?
Fin dalla sua nascita nel 2001, la Fondazione Astrid ha dedicato una parte importante delle sue ricerche e dei suoi paper alle riforme istituzionali e elettorali per ammodernare la democrazia
italiana, superare la crisi di rappresentativitĂ delle sue istituzioni e metterle in grado di affrontare i problemi e le sfide del nostro tempo.
Rispetto alle precedenti ricerche, questo paper ha una finalità più limitata e più schiacciata sull’attualità politico-istituzionale: valutare se, a meno di un anno dalle elezioni politiche del 2023, vi siano spazi e ragioni per modificare la legge elettorale in vigore (il cosiddetto Rosatellum); e, in caso affermativo, analizzare quali potrebbero essere le soluzioni alternative e i
relativi pregi e difetti. Lo facciamo in modo volutamente sintetico, al fine di proporre un quadro di riferimento di facile comprensione per un dibattito che è ancora del tutto aperto, ma che dovrà concludersi, in un senso o nell’altro, in tempi stretti
PĂłlipos linfangiomatosos de las amĂgdalas palatinas en la infancia: Reporte de un caso y revisiĂłn
Background: Lymphangiomatous polyps of the palatine tonsils are rare benign lesions. This entity originates from the lymphoid stroma intermixed with parenchyma, being different from papillary hyperplasia, representing approximately 1.9% of tonsillar neoplasms. Objective: To present a case report and systematic review of the pediatric cases published in the literature. The report case: A systematic review was carried out following the PRISMA guidelines of the reports in PubMed, Elsevier, Google Scholar from 2010 to 2021. 18 articles were found of which 8 females and 10 males were found, the mean age was 14 years, in 15 lesions were unilateral. All cases reported the presence of lymphatic vessels in the histopathological exam. Conclusion: There is variability with age with a similar distribution between genders, being rare there is heterogeneity in its denomination.IntroducciĂłn: Los pĂłlipos linfangiomatosos de las amĂgdalas palatinas son lesiones benignas raras.

ConclusiĂłn: Existe variabilidad entre la edad con distribuciĂłn similar entre sexos; al ser una entidad infrecuente hay heterogeneidad en su denominaciĂłn
Molecular mechanisms and physiological changes behind benign tracheal and subglottic stenosis in adults.
Laryngotracheal stenosis (LTS) is a complex and heterogeneous disease whose pathogenesis remains unclear. LTS is considered to be the result of aberrant wound-healing process that leads to fibrotic scarring, originating from different etiology. Although iatrogenic etiology is the main cause of subglottic or tracheal stenosis, also autoimmune and infectious diseases may be involved in causing LTS. Furthermore, fibrotic obstruction in the anatomic region under the glottis can also be diagnosed without apparent etiology after a comprehensive workup; in this case, the pathological process is called idiopathic subglottic stenosis (iSGS). So far, the laryngotracheal scar resulting from airway injury due to different diseases was considered as inert tissue requiring surgical removal to restore airway patency. However, this assumption has recently been revised by regarding the tracheal scarring process as a fibroinflammatory event due to immunological alteration, similar to other fibrotic diseases. Recent acquisitions suggest that different factors, such as growth factors, cytokines, altered fibroblast function and genetic susceptibility, can all interact in a complex way leading to aberrant and fibrotic wound healing after an insult that acts as a trigger. However, also physiological derangement due to LTS could play a role in promoting dysregulated response to laryngo-tracheal mucosal injury, through biomechanical stress and mechanotransduction activation. The aim of this narrative review is to present the state-of-the-art knowledge regarding molecular mechanisms, as well as mechanical and physio-pathological features behind LTS
