Mise en evidence de la pheromone sexuelle chez les femelles de Blattella germanica L.
1993
L’existence d’une pheromone sexuelle femelle attractive a distance et produite par les glandes pygidiales chez B.germanica a ete demontree. L’ultrastructure de l’epithelium glandulaire a montre des cellules epldermiques banales et des cellules du canal associees a des cellules secretrices, formant les unites glandulaires de classe 3. Chez la jeune femelle vierge, la couche glandulaire est de faible epaisseur, elle augmente progressivement et atteint son maximun entre les 10eme et 13eme jours. Pendant la gestation, elle diminue considerablement puis reprend sa croissance apres le rejet de l’ootbeque. L’attraction des femelles de B. germanica est progressive, elle devient faible pendant la ge…

Jo Nesbø’s The Snowman and the Myth of Týr: Addressing Contemporary Issues through Literary Tradition
2018
Il saggio esplora il modo in cui l'autore di Scandi-noir Jo Nesbø rifunzionalizza il mito norreno del dio germanico Týr (e anche alcuni altri episodi mitologici) nel suo popolare romanzo The Snowman (2007). Nesbø adatta questi miti medievali per creare situazioni ed enigmi allusivi e sfrutta il gioco intellettuale del medievalismo per creare un significato semanticamente denso. Il romanzo quindi esplora e considera varie questioni contemporanee tra cui, per esempio, il valore della “verità” rispetto alla percezione individuale (e contestuale), la supposta dicotomia tra vittima e carnefice, e il conflitto tra individuo e società. L'analisi dimostra non solo la densità semantica di The Snowma…
La construction de métaphores scientifiques dans les discours publics de médecins germanophones au XIXème siècle : contribution à une approche diachr…
2016
National audience; Cette proposition de communication vise à interroger la notion de métaphore à travers un double prisme. D’une part, non pas comme ‘figure’, ainsi qu’elle l’est dans une longue tradition à l’intersection entre rhétorique et stylistique, mais comme schéma de pensée à la suite de la théorie des métaphores conceptuelles initiée dans les années 1980 par Lakoff/Johnson et largement discutée, critiquée et enrichie depuis lors. D’autre part, à partir d’un corpus de textes pouvant être qualifiés d’hybrides puisque constitués de discours publics de médecins abordant des questions scientifiques, mais aussi plus globalement sociétales voire philosophiques. Ces textes, qui ne sont pas…
I Segni premonitori del Giudizio Universale in un inedito testo tedesco del XV secolo
2022
Numerous lists of the premonitory signs of the Last Judgment and wider narratives focussing on the same motif, which presents variants and articulated typologies, circulated throughout the Middle Ages, both in Latin and in the vernacular languages. Also in Germany the motif continues to be present in literature up to the threshold of the modern age, with the Lutheran Reform which is, also in this case, a watershed. The purpose of the contribution is the philological-literary analysis of a prose composition, in late German, devoted to the 15 Signs of Judgment, still unpublished, preserved in the ms. München, BStB cgm 522 (ff. 163v-166v), datable around 1470. The codex contains a miscellany o…

LA LETTERATURA ‘VISIONARIA’ E LA RAPPRESENTAZIONE DELL’ALDILÀ NEL MEDIOEVO TEDESCO
2021
Il saggio fornisce una rassegna delle visioni dell’aldilà nella tradizione del medioevo tedesco, partendo dalle fonti classiche e da quelle latine di epoca carolingia fino agli inizi della documentazione letteraria in volgare. Nello specifico, il focus della ricerca è rivolto allo studio dell’affermarsi dei topoi più significativi delle visioni escatologiche e della topografia dell’oltretomba nella Germania dell’Alto Medioevo, fino al XII secolo, con l’intento di far risaltare il contributo delle visioni di area tedesca alla costruzione dell’impianto ideologico su cui poggia la concezione del purgatorio – la cui dottrina si affermerà più tardi, in epoca basso medievale – e di contestualizza…
Old English byrððīnenu: the Anglo-Saxon midwife
2018
Midwives were clearly viewed as professionalized figures in the Mediterranean world of antiquity and late antiquity and they were responsible for women’s healthcare, such as gynecological and obstetrical needs. They were referred to in Roman law, admonished in Christian edicts and memorialized in statues and inscriptions. Their status is attested to by medical texts specifically intended for midwives’ use dating from at least the third century B.C. to the sixth century A.D. According to Green, professional midwives disappeared along with the slow disintegration of the urban environments that supported medical specialization and reemerged as a specialized profession only in the thirteenth ce…
Heterocyclic systems containing tin(IV)—XIII [1]. Possible ceasing or inversion of the structuraltrans influence during the course of a bimolecular n…
1997
Abstract In the series of the heterocycles X[(CH2)3]2SnR2 (16 newly synthesized compounds and two taken from the literature) and in the germanium analog BuiN[(CH2)3]2GeCl2, the donor group X (= NMe, NBz, NBui, NPri, O, S) intramolecularly attacks the Lewis acidic atoms Sn or Ge. Eight structure determinations (and, in addition, 2 taken from the literature) are compared. The nucleophilic attack at Sn is stronger for the ligands R2 =Cl2 than for the more electronegative R2 = (OSiPh3)2. Overall the familiartrans influence holds: simultaneous approach of X and weakening of the ligand R (trans). In three cases of subtly graded donor strength a slight inversion or ceasing is observed: shorter dis…
Light harvesting with Ge quantum dots embedded in SiO2 and Si3N4
2014
Cataloged from PDF version of article. Germanium quantum dots (QDs) embedded in SiO2 or in Si3N4 have been studied for light harvesting purposes. SiGeO or SiGeN thin films, produced by plasma enhanced chemical vapor deposition, have been annealed up to 850 degrees C to induce Ge QD precipitation in Si based matrices. By varying the Ge content, the QD diameter can be tuned in the 3-9 nm range in the SiO2 matrix, or in the 1-2 nm range in the Si3N4 matrix, as measured by transmission electron microscopy. Thus, Si3N4 matrix hosts Ge QDs at higher density and more closely spaced than SiO2 matrix. Raman spectroscopy revealed a higher threshold for amorphous-to-crystalline transition for Ge QDs e…
