Authors: BATURU Muharrem , BAYRAK Ömer , ÖZTÜRK Mehmet , SEVİM Özcan , ŞEN Haluk , SEÇKİNER İlker
Published: January 2024

Objective: To compare the effects of an alpha-blocker (alfuzosin) versus a herbal agent, “Tutukon®,» on stone-free rates in patients who underwent retrograde intrarenal surgery (RIRS).
Material and Methods: We evaluated seventy-five patients who underwent RIRS prospectively consecutively and reported retrospectively between January 2020 and June 2020. Patients were divided into three groups to analyze the effect of medications on stone-free rates after RIRS. “Tutukon®» was prescribed to the first group, alfuzosin 10 mg to the second group, and only dexketoprofen to the third group as the control group. The patients were re-evaluated for stone-free rates after the fourth week of surgery.
Results: Among the groups (Tutukon®/Alfuzosin/Control), no differences were observed in terms of age (44.4±15.71/43.16±14.05/46.00±14.43), stone size, stone location and extracorporeal shock wave lithotripsy (ESWL) history (p>0.05). Complete stone-free rates at the fourth postoperative week; Group 1 (Tutukon®) was 96%, group 2 (alfuzosin) 84%, and group 3 (control) 76% (p=0.163), and the stone-free rate in Group 1 was significantly higher than that in the control group (Group 1 vs. 3; p= 0.044, Group 2 vs. 3; p=0.363). Evaluation of completely stone-free patients and patients with clinically insignificant residual stones showed no difference between the groups (p=0.234).
Conclusion: The data obtained from the use of Tutukon® have similar results to the use of alfuzosin in medical expulsive therapy, suggesting that it may be a preferred phytotherapy method for fragment expulsion after endoscopic stone surgery.
Species dependent correlation analysis and regression models of body weight on linear body measures in indigenous sheep and goats of Zimbabwe
Authors: Assan Never , Musasira Michael , Mpofu Maphios , Mwareya Nicholas
Published: January 2024

Measurements of live weight in goats and sheep are an important source of information for a range of scientific fields and applications in animal husbandry activities. The study was conducted to investigate the relationship between body weight and body measurements and to predict live body weight from body measurements in indigenous Matabele goats and indigenous Sabi sheep at Matopos Research Station in Zimbabwe. For this purpose, data on body weight (BWT) and linear body measurements (LBM) such as heart girth (HG), body length (BL), wither height (WTH), and rump height (RH) were collected from randomly selected females of each species at the age of 4 years. The corresponding means, standard deviations (SD), and coefficients of variation (CV) were determined for body weight and linear body measurements. Bivariate correlations between bodyweight and linear body measure characteristics were also determined. Simple and multiple regression were used to develop a model to predict BWT using linear body measures. Indigenous Matabele goat females’ CV ranged from 15.77% to 22.68%, while indigenous Sabi sheep females’ CV ranged from 19.16% to 19.37%. The CV was calculated by dividing the mean by the standard deviation. At 4 years of age, the mean BWT of the indigenous Sabi sheep and female Matabele goat were 35.96 ± 0.83 kg and 27.90 ± 0.66 kg, respectively. In indigenous Matabele goat females, the average linear body measures were HW (74.20 ± 0.53 cm), WTH (48.55 ± 0.53 cm), BL (47.53 ± 0.61 cm), and RH (57.50 ± 0.88 cm). The mean values for native Sabi sheep were 63.33 ± 0.70 cm, WTH (52.00 ± 0.80 cm), BL (51.26 ± 0.78 cm), and HW (85.56 ± 1.04 cm). The results showed a strong and positive correlation between BWT and linear body measures in female indigenous Matabele goats. The phenotypic correlation values were HG (r = 0.79), BL (r = 0.70), WTH (r = 0.68), and RH (r = 0.56), in decreasing order. In indigenous Sabi sheep, the phenotypic correlation for BWT and linear body measurement was high and positive for HG (r = 0.73), and positive and moderate to low with WTH (r = 0.41), BL (r = 0.32), and RH (r = 0.36). Again, the results also indicated that HG had a high and positive phenotypic correlation with BL (r = 0.53), while modest correlation was observed with HG and WTH (r = 0.41) and HG and RH (0.32). The optimal regression models for easily measuring body weight using HHG are BWT = −46.711 + 1.006 HG (R2 = 60%) and BWT = −15.209 + 0.586 HG (R2 = 53%) for indigenous Matabele goats and indigenous Sabi sheep, respectively. It is recommended that smallholder farmers use HG measurements to estimate body weight in both indigenous Sabi sheep and indigenous Matabele goat females at the age of 4 years.

Mollis – ἁπαλός : La démarche féminine des vers poétiques dans l’élégie romaine et ses modèles hellénistiques
Authors: Klein Florence
Published: January 2024

Cet article se propose de voir dans l’elegidarion capillorum d’Eumolpe, qui fait l’éloge de la chevelure perdue d’Encolpe et de Giton, une attaque contre les afféteries stylistiques des poètes néo-callimachéens dont Ovide était, à l’époque impériale, considéré comme le modèle. Pour cela, le texte du Satiricon s’appuie sur une métaphore genrée de la critique littéraire qui caractérise comme efféminé un style inutilement alambiqué, avec l’image de la coiffure, des bouclettes et des frisottis d’une écriture trop précieuse. Dans cette « petite élégie capillaire » qui vise conjointement ses deux modèles « génériques », l’élégie d’Amours I, 14 et la Coma Berenices, nous observerons le jeu intertextuel complexe qui se noue par rapport à la poésie ovidienne, à laquelle Eumolpe emprunte non seulement l’utilisation métapoétique du thème de la coiffure en Am. I, 14, mais aussi la distinction genrée entre coiffure virile et coiffure féminine (ou efféminée) prônée par le magister amoris dans l’Art d’Aimer : en superposant ces deux hypotextes, l’elegidarion capillorum retourne le modèle ovidien contre lui-même, en faisant de la chevelure, qui figurait chez Ovide une poétique callimachéenne érudite et raffinée, la métaphore de l’écriture artificielle et creuse des compositions néo-alexandrines.
Aristotle’s Unanswered Questions: Women and Slaves in Politics 1252a-1260b
Authors: Parker Holt N.
Published: January 2024

Aristotle is more straightforward than his interpreters. A number of scholars have championed an Aristotle guided by pure inductive observation to reach a theory of the inferiority of women and slaves. This view, however, is contrary both to Aristotle’s expressed method and his stated purpose. He begins from the phainomena and his explicit goal is to defend them and the advantages of master and husband. The current power structure is founded on nature and is and must be logically and genetically superior to the arguments he makes in its favor. In general, scholars have explicated either the argument about slaves or that about women. However, each is inescapably fettered to the other. The unquestioned inferiority of slaves is the analogical basis for the hierarchy of male over female (e.g. 1252a31). The unquestioned natural inferiority of women the basis of the proof of the existence of the natural slave (54b12-16). Aristotle reveals the uncertain heart of his argument in a series of unanswered rhetorical questions (59b23-37). There are three parts to his defense. The philosophical move is to reject Plato’s unity of virtue. Mere difference in quantity (Plato’s solution) provides contingent not absolute rule. The teleological move argues from different virtues to different essences for women and slaves. Aristotle creates separate entities to be ruled. The rhetorical move is to blend analogies based on the “natural” difference between male and female with the hierarchical difference between master and slave. Thus we reach the master trope of Western philosophy: man is spirit/culture, woman is matter/nature. A series of misreadings of Aristotle’s purposes and arguments reveal how successful he has been in anchoring ideology in a politicized nature. Philosophy is not a purely intellectual exercise; it is also a call to moral action. We must ask and answer Aristotle’s rhetorical questions.
Veturia : négociatrice et ambassadrice de Rome
Authors: Dubosson-Sbriglione Lara
Published: January 2024

La diplomatie peut se définir comme la conduite de négociations entre personnes, groupes ou nations en vue de régler un différend sans avoir recours à la violence. Dans le monde romain, la diplomatie fut indéniablement une affaire d’hommes. Pourtant, certaines femmes ont pu agir, en cas de crise grave, comme ambassadrices envoyées auprès de l’ennemi afin de négocier une paix ou un accord au nom de Rome. C’est le cas de Veturia, qui fut envoyée avec un groupe de matrones dans le camp ennemi pour parlementer avec son fils Coriolan, qui avait pris la tête des armées volsques contre sa propre patrie. Dans le cadre de cette étude, je me pencherai sur les circonstances qui ont permis à Veturia d’accéder à une fonction, en principe réservée aux hommes, ainsi que sur la manière dont celle-ci lui a été confiée. Je m’intéresserai également aux qualités et compétences particulières dont elle a dû faire preuve pour pouvoir réussir là où les hommes avaient échoué avant elle. Enfin, je m’interrogerai sur les raisons qui ont poussé des auteurs antiques tels que Denys d’Halicarnasse, Tite-Live et Plutarque, à faire de Veturia un exemplum digne d’être conservé dans la mémoire collective.
Womanly wailing? The mother of Euryalus and gendered reading
Authors: Sharrock Alison
Published: January 2024

Feminist reading of the classics requires a difficult negotiation between the struggle to be heard and the struggle to avoid appropriation. The aim of this paper is to explore some few words of Virgil, especially those reacting to the mother of Euryalus’ reaction to her son’s death, and those of his readers through the ages, as a paradigm case of a wide theoretical and philosophical issue in feminist literary criticism. The fundamental question asked in this paper is whether feminist readers of the classics should concentrate on listening to differentiated female voices or on arguing for some form of what we might metaphorically call “equal rights” among the protagonists of ancient literature.
Narrative Performanz. Vorschlag zu einer neuen Lektüre von Geschlecht in taciteischen Texten
Authors: Späth Thomas
Published: January 2024

Tacitus kennt Geschlecht nicht als Kategorie der historischen Analyse. Und dennoch schreibt sich Geschlecht in seinen Text ein und bestimmt sein historisches Urteil: In der Darstellung männlicher und weiblicher Figuren verwendet Tacitus die Konzepte von Weiblichkeit und Männlichkeit des Geschlechtsdiskurses seiner Zeit. Er konstruiert seine Figuren, indem er ihnen bestimmte Konzepte aus dem breiten Spektrum der Bilder, mit denen die Kultur des Prinzipats die Vorstellungen von Geschlecht verbindet, zuordnet. Damit lassen sich aus den taciteischen Texten zwar normative Konzepte von Männlichkeit und Weiblichkeit erkennen, aber kein Idealtypus einer römischen Frau oder eines römischen Mannes. Aus der Untersuchung der Darstellung des Todes der zwei Kaiser Otho und Vitellius in den Historien, der biographischen Konstruktion im Agricola und der Ausgestaltung von weiblichen und männlichen Figuren in den Annalen entwickelt der Beitrag die These, dass die im Text dargestellten Figuren Ergebnis einer narrativen Performanz sind, in der Geschlechtsvorstellungen mit gesellschaftlichen, politischen und situativen Positionen verknüpft werden. Und er postuliert, dass diese intersektionale narrative Performanz auf eine Performanz von Geschlecht in der gesellschaftlichen Realität verweist.
Baliatico, αἰδώς e malocchio: capire l’allattamento nella Grecia di epoca arcaica e classica anche con l’aiuto delle fonti romane
Authors: Pedrucci Giulia
Published: January 2024

In passato alcuni studiosi hanno sostenuto che le donne greche, come quelle romane descritte da Sorano, non allattassero personalmente i loro figli, preferendo assumere nutrici a questo scopo. Sorano, però, parlava di una “moda” in voga soltanto nella Roma imperiale. Da un’attenta analisi delle fonti greche, infatti, si può intuire che le madri nella Grecia di epoca arcaica e classica tendenzialmente allattassero. Probabilmente per questa ragione le fonti greche non si sono mai soffermate su problemi al contrario molto dibattuti a Roma, come le conseguenze che poteva avere un latte alieno sul bambino, e, di conseguenza, sull’intero genos. Scandagliano però con attenzione le testimonianze greche possiamo cogliere anche in esse qualche riferimento, seppure meno esplicito, all’esistenza di latti con caratteristiche diverse e in grado di veicolare determinati caratteri genetici. Una volta stabilito che le donne elleniche allattavano, si è cercato di dare una spiegazione alla rarità di immagini di donne che allattano nella Grecia continentale, individuando principalmente tre motivi: il concetto molto radicato nella cultura greca di aidós, la teoria dell’emogenesi dal latte materno dal sangue mestruale e un più generico sentimento di “scaramanzia” e paura connessi con alcuni momenti molto delicati della vita della donna e del bambino (si pendi a esempio al malocchio). Contemporaneamente, si è cercato di prendere le distanze da concetti molto abusati in passato, come tabù, magia e misoginia.
Entre pax y concordia. Las mujeres y las virtudes de paz ligadas al poder en la Roma antigua
Authors: López Cándida Martínez , Vivas Carmen María Ruiz
Published: January 2024

Pax y concordia fueron dos conceptos, virtudes y deidades que representaron distintas facetas de la paz en la política y mentalidad romana. Su valor, significado y representación visual evolucionaron según las circunstancias, necesidades e intereses en el periodo republicano y el Alto Imperio. Ambas se representaron con forma y cuerpo de mujer, y compartieron símbolos, pero adquirieron matices diferentes en su significado, ámbitos de proyección, así como en los posibles agentes para su logro. Desde una perspectiva de género este trabajo pone el foco en la relación desigual de ambos conceptos con mujeres y hombres, y en cómo las distintas funciones y roles de género determinaron que la concordia formase parte de las posibilidades de agencia de las mujeres, mientras que el logro de la pax se proyectó como potestad de los varones. En este artículo se analizan fuentes escritas, epigráficas, iconográficas y numismáticas para ofrecer una visión en conjunto de cómo las mujeres se proyectaron en el espacio público y político desde el papel de género que era esperable de ellas, con unas funciones muy vinculadas al mantenimiento de la concordia.
‘Divine Corinna’: Pre-Twentieth Century Receptions of an Artistic Authority
Authors: Thorsen Thea S.
Published: January 2024

Based on evidence that is very rarely considered together in scholarship, this paper argues that Corinna of Tanagra has been associated with an idea of artistic authority in antiquity. This is a subject on which the ancient reception of Corinna differs considerably from the modern appreciations of the poet. By applying the hermeneutical approach of reception studies, this paper shows that the presence of an idea of Corinna as an artistic authority may be found in both ancient texts and the figurative arts, as well as in postclassical scholarship. Here, in her pre-twentieth century receptions, Corinna is portrayed both as honoured in her own right and as superior to the poet Pindar, who according to the ancient tradition was her contemporary, compatriot and fellow student. As will be argued, the shift in Corinna’s reception history occurred with the 1907 publication of the Berlin Papyrus, which contained the largest extant fragments of her output to date. From this point onwards, a debate on Corinna’s date, which, according to some, may have been later than Pindar’s, has eclipsed the authoritative aspects of her reception history. The article closes by suggesting that a re-evaluation of the idea of Corinna as an artistic authority, facilitated by a reception studies approach, should urge current scholarship to assess the debate about her date and place in the history of classical literature afresh.
From Victor to Victim: Metadrama and Movement of Plot in Seneca’s Hercules Furens
Authors: Frangoulidis Stavros
Published: January 2024

In Seneca’s Hercules Furens there are two distinct narratives with opposing objectives, one authored by Juno, the other by Hercules. The former seeks to prevent the hero from becoming a god, by directing him to carry out an assault on heaven and eliminate his family, and the latter seeks to implement his vision of the new Golden Age by purging the world of remaining evils. As the two plans collide, they generate confusion in the minds of both Hercules and Amphitryon, in part because Juno is able to exploit Hercules’ own overweening ambition. The play associates this kind of ambition with tyrannical behavior. When Hercules’ Juno-sent frenzy results in the slaughter of his family, the tragic hero is rendered an intratextual double of the tyrant Lycus, fulfilling the tyrant’s goal of eliminating the Theban royal line. This constitutes an attack on Thebes itself, the earthly analogue of heaven. This poetological dimension – in which Hercules’ acts follow his own scripted vision set beside that devised by Juno – constitutes a significant Senecan innovation vis-a-vis the Euripidean Ἡρακλῆς Μαινόμενος in its treatment of the mythic plot. The dual authorship and ultimate overlap of the two previously opposed plotlines highlight the complex nature and meaning of Hercules’ responsibility.
Ideal Beauty and Adornment: A Roman Portrait of a Young Woman
Authors: d’Ambra Eve
Published: January 2024

The article focuses on a Roman portrait of a young woman in the Metropolitan Museum of Art from the early second century C.E. The marble head, though striking for its beauty and high quality of craftsmanship, cannot be identified. It is also a fragment from a statue without an archaeological context or findspot. How do we approach a sculpture about which so much cannot be known? A visual analysis of related portraits, along with a discussion of the tradition of epitaphs, literary accounts, and artefacts of girls’ lives, such as dolls, suggest how maidens were commemorated and valued in Rome.
La place de la femme et la question du mariage dans la réflexion sur l’amour et les femmes du début du Cinquecento
Authors: Boulègue Laurence
Published: January 2024

Au tout début du Cinquecento italien, le De mulieribus (1501) de Mario Equicola offre une défense des femmes fondée non seulement sur l’opposition, répandue chez les humanistes, aux thèses misogynes héritées de la tradition médicale antique et médiévale, mais sur une critique vive de la société patriarcale et de la soumission des femmes, en particulier au sein de l’institution du mariage. Ce thème apparaît comme un critère intéressant pour évaluer les thèses sur la condition féminine à une époque où les femmes sont particulièrement représentées dans la nouvelle littérature d’amour et de cour. Expression maximale du renouveau du débat sur la question féminine, l’ouvrage d’Equicola reste cependant une exception au sein des traités et des dialogues italiens qui fleurissent alors, bien que le modèle philosophique de la réflexion sur les rapports amoureux, remis à l’honneur par Marsile Ficin dans le Commentaire sur le Banquet de Platon (1469), soit peu à peu effacé au profit d’une célébration du couple hétérosexuel et du mariage conçu idéalement comme le lieu harmonieux d’un partenariat entre les époux. Cet article se propose d’étudier les principaux témoins de cette évolution non rectiligne dans les premières années du xvie siècle en Italie de façon à mettre en perspective la singularité du De mulieribus de Mario Equicola.
Lesbia as Procuress in Horace’s Epode 12
Authors: Skinner Marilyn B.
Published: January 2024

Recent innovative readings have shown that Horace’s Epodes is an experimental contribution to the iambic tradition using impotence as a structuring trope. In the light of those analyses, one corollary problem demanding re-examination is the Augustan poet’s relationship to his “suppressed precursor” Catullus, who in the Epodes as in the Odes goes unacknowledged although his presence is constantly felt. When composing iambics Horace apparently employs Catullus’ unorthodox generic practices as foils. Contextually distorted echoes may therefore call attention to neoteric conventions from which Horace dissociates himself. This paper tests that premise by attempting to clarify one hitherto unexplained detail of Epode 12: its mention of a go-between named “Lesbia”, who in the reported words of the speaker’s mistress is blamed for making the match. It argues that the epode mocks Cornelius Gallus’ and perhaps Propertius’ elegiac constructs of masculinity by tracing them back, through a network of allusions, to their Catullan origins and so exposing the absurdity at their core.
Sulpicia, Gallus et les élégiaques. Propositions de lecture de l’épigramme 3.13
Authors: Fabre-Serris Jacqueline
Published: January 2024

Cet article, qui étudie l’épigramme 3.13 d’un point de vue intertextuel, met en évidence, à partir de convergences avec Lucrèce, Virgile et les autres poètes élégiaques, le fait que son modèle principal est, ce qui n’est pas surprenant dans un texte proémial, le fondateur du genre, Gallus. Il analyse comment Sulpicia, dans sa transposition au féminin de l’élégie, reprend et remanie des mots et des motifs galliens, qu’elle partage en particulier avec Properce, en même temps que la façon dont elle répond à la critique du furor élégiaque développée par Virgile à propos de Didon. Il se termine sur une étude de la réception de ce texte dans l’élégie 3.8 de l’amicus et dans l’Héroide 4 d’Ovide, tous les deux moins audacieux sur le plan moral.
Femmes au vase sur la scène tragique : enjeux dramatiques et symboliques
Authors: Noel Anne-Sophie
Published: January 2024

Quand un personnage féminin paraît dans l’orchestra de la tragédie grecque, il y a de fortes probabilités pour qu’il porte un vase entre ses mains, ou qu’il soit suivi d’un ou plusieurs figurants muets assignés à cette fonction. En effet, l’usage de l’objet justifie dramatiquement la sortie des femmes hors de l’oikos, à des fins religieuses ou domestiques : libations ou corvée d’eau. Ce sont ces « scènes à vase », récurrentes dans les tragédies conservées d’Eschyle, de Sophocle et d’Euripide, que nous examinerons comme un ensemble cohérent, dans des perspectives dramatique, dramaturgique et symbolique, afin de mettre en lumière ce que l’usage de cet accessoire théâtral dit de l’identité féminine. Objet polysémique et polyvalent, associé au pouvoir de vie et de mort attribué aux femmes, le vase permet de représenter les personnages féminins sur la scène théâtrale comme des figures maternelles et nourricières ; quand le personnage est une numphè, une vierge en âge d’être mariée – à l’exemple d’Électre, Ismène, Hermione – le départ, vase en main, vers un espace extérieur à l’oikos, est toujours synonyme de danger et d’agression potentielle. Dans ces circonstances, le vase, menacé de chute ou de bris, peut apparaître comme un signal visuel traduisant le rapport problématique de ces numphai au mariage.
Beauty and Sex Appeal in Aristophanes
Authors: Robson James
Published: January 2024

This article undertakes a survey of the plays of Aristophanes in order to reveal what they tell us about concepts of attractiveness and body image. Old Comedy presents us with a view of beauty from a largely male perspective, and, instructively, the vast majority of comments that male characters make concern the appearance of females rather than boys or youths. Women are regularly discussed in comedy in terms of their body parts, e.g. and especially their breasts, and the ideal woman is, perhaps predictably, youthful. Further characteristics in women such as pale, smooth skin and well-tended pubic hair also attract positive comments. Male beauty is perhaps more complex. One ideal is certainly that of the broad-shouldered, tanned youth with gleaming skin and a small penis who exercises in the gymnasium. But there is also evidence of pale-skinned, effeminate youths being viewed in a positive light. In addition to looks, clothing and scent can add to women’s erotic appeal, and actions such as playing with phallic-shaped food are seen as flirtatious in both sexes. This article explores overlaps in the ways in which male and female beauty is described and suggests that these correspondences are partly explicable through the similar ages at which boys and girls are considered to be at their peak. The discussion also reveals the almost complete lack of attention paid to facial features – both in Aristophanes and classical Greek literature as a whole.
Mulier, femina, uxor, coniunx: die begriffliche Kategorisierung von Frauen in den Briefen von Cicero und Plinius dem Jüngeren
Authors: Hindermann Judith
Published: January 2024

Eine sprachliche Analyse der Termini, mit denen Cicero und Plinius in ihren Briefen von Frauen und Männern sprechen, ist bislang nicht umfassend erfolgt. Mit mulier, femina, uxor und coniunx werden die vier wichtigsten Termini zur Bezeichnung von Frauen auf Art und Frequenz der Verwendung in den beiden Briefcorpora untersucht und interpretiert. Dabei zeigen sich grosse Unterschiede zwischen den beiden Autoren. Anders als bei Cicero wird in Plinius’ Briefsammlung ein Werkkonzept deutlich, das die Auswahl seines weiblichen und männlichen Personals bestimmt. Plinius’ Selbstinszenierung verlangt einen Kreis herausragender Personen, die ihn umgeben und zu denen auch prominente, namentlich genannte feminae gehören. Cicero hingegen bevorzugt den Begriff mulier und verwendet ihn meist als Kollektivbezeichnung im Plural. Der Terminus uxor für ‚Ehefrau‘ ist in Plinius’ Briefen weit häufiger zu finden als bei Cicero, der zwischen uxor und coniunx variiert. Während das biologische Geschlecht von Frauen bei Plinius und Cicero kaum thematisiert wird, ist das soziale Geschlecht durch den Zivilstand der Frau bestimmt, d.h. durch ihre Rolle als uxor und das Verhältnis zum Ehemann. Wie bei Cicero bleiben die Ehefrauen auch bei Plinius meist namenlos. Neu wird in Plinius’ Briefen die Rolle des Ehemannes (maritus) eingeführt und als Feld der sozialen Distinktion genutzt.
Genre et Gender : usages et enjeux de l’emploi de durus chez les élégiaques
Authors: Fabre-Serris Jacqueline
Published: January 2024

Durus est l’adjectif associé au nom de Gallus, directement par Quintilien et indirectement par Ovide, dans les deux jugements qu’ils portent sur lui. Mon hypothèse est que ce choix dénote l’importance de cet adjectif dans le traitement gallien de l’élégie, ce que peuvent confirmer les deux emplois de durus dans le passage de la Bucolique 10 où Virgile donne la parole à Gallus. Durus y qualifie d’une part Mars dans le contexte de combats, d’autre part Lycoris, alors inconstante en amour. L’idée que durus ait eu une valeur générique peut apparaître paradoxale, l’opposition mollis/durus étant utilisée précisément pour opposer l’élégie à l’épopée sur le plan de la thématique (amour versus guerre), de la métrique et de la stylistique. En fait le relevé des multiples occurrences de durus révèle que les élégiaques l’utilisent tous, en l’associant soit à la puella (à cause de son insensibilité ou de son inconstance), soit au genre de vie qu’elle impose alors à son amant, et qui, du fait qu’il l’endure, le contraint à se montrer lui aussi durus (capable de le supporter). Mais ce dernier doit être en même temps mollis : user de prières et de blanditiae pour faire changer la femme aimée de comportement, autrement dit, pour la mollire. Je défends l’hypothèse que l’usage de l’adjectif durus a joué un rôle essentiel dans la mise en place d’une conception nouvelle des rapports de sexe dans la relation amoureuse, caractérisée par l’échange et donc le partage de qualités, traditionnellement associées l’une à la femme, la mollitia, l’autre à l’homme, la duritia. Le passage de la métaphore gallienne du « dur » seruitium amoris (opposé, dans les Amores, aux « dures » campagnes militaires, synonymes d’épreuves et de dangers mais aussi de succès et de trophées) à la métaphore de la militia amoris, développée par Properce et Ovide, s’explique par le réinvestissement dans le genre de vie de l’amant des qualités et valeurs associées au genre de vie du soldat : endurance, hardiesse et victoire finale.
Kunskapsunderlag för hållbar förvaltning av svenska öringbestånd
Authors: Magnusson Katarina , Dannewitz Johan , Kagervall Anders , Palm Stefan
Published: January 2024

Öringen har en komplex livscykel och bestånd kan innehålla varierande grad av stationära och vandrande individer. Öringen finns i många miljöer, från havet till fjällsjöar, och har bland annat krav på goda strömvattenmiljöer, fria vandringsvägar och en god miljö i kustområdet. Många bestånd av öring är generellt sett små och därför känsliga för negativ miljöpåverkan och fiske. Risken för genetisk utarmning är stor i små och reproduktivt isolerade populationer. Där möjlighet finns har dock öringen i regel ett genutbyte med andra närliggande populationer, vilket minskar riskerna för förlust av genetisk variation och inavel samt medför ökad återhämtningsförmåga. Dagens bestånd av havsöring är generellt svagare än historiskt, då stora arealer i rinnande vatten inte längre kan nås på grund av vandringshinder. Fisket efter öring domineras av fritidsfiske vars fångstmängder och omfattning är dåligt kända. För att skatta öringens beståndsstatus behöver specifika uppföljningsbara förvaltningsmål för öring tas fram. Förekomsten av många små bestånd medför svårigheter (och höga kostnader) för övervakning och bedömning av beståndsstatus för enskilda lokala bestånd. Förvaltningen av öring bör därför vara områdesbaserad, där varje område har liknande miljö- och påverkansfaktorer. Förvaltningen bör även vara ekosystembaserad och adaptiv, för att snabbt kunna anpassas till rådande förhållanden (torka och andra påverkansfaktorer). Adaptiv förvaltning kräver flexibla regelverk och en i övrigt transparent förvaltning, samt datainsamling/övervakning i typiska öringvattendrag spridda över hela landet inklusive ett antal representativa (för enskilda förvaltningsområden) ”indexvattendrag” med utökad datainsamling.
MICROSTRUCTURE AND PROPERTIES OF LASER-WELDED BUTT JOINTS OF AlSi1MgMn ALUMINIUM ALLOY

The process of autogenous laser welding of butt joints of aluminium alloy AlSi1MgMn plates with thickness of 3.0 mm was investigated. The Yb:YAG disk laser was used in the study. The aim was to determine the influence of the basic parameters of laser welding on the joint quality, fusion zone geometry, microhardness distribution across the butt joint, structure and microstructure of fusion zone (FZ) and heat affected zone (HAZ) was studied and determined. The chemical composition of the base metal was determined by spark emission spectroscopy, while the phase constituents were determined by XRD analysis. Results of the study have shown that the geometry of welds is proper without excessive imperfections. No voids were found the FZ. However, weld face of the joints are slightly convex, while the roots are slightly concave. Microscopic observations showed no discontinuities in the fusion zone of the welds. A significant decrease in hardness in the FZ was observed. The hardness in the FZ of the test joints is approx. 67÷70 HV0.1. The fracture of the samples during tensile tests occurred in the FZ or at the boundary FZ/HAZ, and the tensile strength was ranged from 200MPa to 220MPa.

In the conditions of the increasingly accentuated development of industrial and household products, the reuse of material waste with the aim of reducing environmental pollution has become an increasingly important necessity. This study presents the obtain of flexible magnetic composites based on cotton fabrics, acrylic rubber, powder from used tires and magnetite powder. The textile support was purchased from the local market (Tesatura Iași, Romania) and was made from 100% recovered cotton fibbers, with a mass of 143g∙m-2 and an average thickness of 0.28mm. The rubber was an acrylate type (AR) (NipolR AR 51) with the next characteristics: (ρ = 1100Kg∙cm−3 at 25oC, Mooney viscosity ML (1+4) at 100oC = 55; Tg = -4 oC). The rubber powder (PW) (with more natural rubber in composition) was obtained by grinding at temperature under 10 oC from used motorcycle tires obtained from the local market. The characteristic of rubber powder was: particles size up to 100 μm, moisture content 0.25 %, density (ρ) = 1060 Kg∙m-3. Magnetite was obtained according to the literature [1]. The composites were obtained at the weight ratio of PW/AR/ (20/80) with added magnetite powder according to desired mass fraction. The materials and composites were characterized using infrared spectroscopy (FTIR), dynamic light scattering (DLS) technique, X-ray diffraction (WAXD), scanning electron microscopy (SEM) and vibrating sample magnetometer (VSM). These composites can be used as raw materials for smart materials in the high-tech applications in the production of the DC motors, recording apparatus, magnetic screens, radar technology, memory devices, magnetic and electromagnetic sensors, materials for medicine and environmental protection or in the electronic devices where flexibility is required.

The aim of the work was to determine the structure and hardness of the parent material, the heat affected zone and the weld in butt joints of thin sheets with a thickness of 1.0 mm made of Inconel 625 nickel superalloy welded by TIG (tungsten inert gas) method. Test joints were made with different linear welding energy in the range of 70 - 145 J/mm. The obtained welded joints were subjected to visual tested, macroscopic metallographic examinations, observations of the structure on a light microscope, observations of the structure in a scanning electron microscope and a hardness measurement. The geometrical parameters of the joints were also specified. Chemical composition of structural components of selected areas of the weld, heat affected zone and parent material was determined by surface and point X-ray microanalysis. The range of linear energy was determined in which joints of thin sheets made of the tested superalloys in laboratory conditions show the best quality.

Abrasive water jet (AWJ) has gained an important place among the machining technologies due to its capacity to cut complex shapes in various materials without thermal effects and with low cutting forces, but it also has a reduced environmental impact. A key element for the quality of the cut is the amount of energy contained in the abrasive jet. The dissipaton of energy leads to kerf taper, high values of surface roughness, surface striations, the deviation of the water jet (jet drag), and even insufficient penetration. The current paper investigates the influence of process parameters on the quality of the cut for a S235 steel alloy. The quality of the cut was assessed by four parameters: entrance width of cut (Li), exit width of cut (Le), perpendicularity (u) and kerf angle (α). The experiments were organized according to a D-optimal Response Surface Method. Analysis of variance (ANOVA) was used for the development of a mathematical model that correlates the influence of process parameters on the quality of the cut. Finally, an optimization of the process parameters was proposed.

The gas turbine industry strongly committed to develop gas turbines operating with 100% hydrogen till 2030, such fully supporting the transformation of the European natural gas grid into a renewable-based energy system by overcoming technical challenges and ensuring that this transformation takes place swiftly. By extending the fuel capabilities of gas turbines to hydrogen, their role can become predominant in the energy transition period but also in long-term energy strategies. In combined cycle configuration (CCGT), gas turbines are already the cleanest form of thermal power generation. For the same amount of electricity generated, gas turbines running on natural gas emit 50% less CO2 emissions than coal-fired power plants. Mixing renewable gas (e.g., green hydrogen, biogas) with natural gas enables further reduction in net CO2 emissions. In this paper pure hydrogen and blends of hydrogen methane will be studied as fuel in order to predict the behavior of afterburner system with a new designed geometry.

The problem of manufacturing process optimization is one of the most addressed issues across literature concerning the manufacturing field. Until now, this optimization has been based on indirect description of manufacturing, through prefabricated algorithmic models (be they analytical or numerical), as well as on information processing, by composing this kind of models. This is why the optimization is difficult and complicated, even in the case of the simplest processes. This paper presents a new approach of the manufacturing optimization concept, having as main defining aspects: i) The manufacturing process is regarded as decisional instead of physical process, ii) The optimization object is the manufacturing task, defined as product transition from current state up to final state, iii) The manufacturing model consists in a dataset, and, iv) The optimization problem solution consists in task configuring, task accomplishment, and task modeling. According to the new approach, the optimization result consists in the ensemble formed by an optimal structure (optimal configuration of the given task), an optimal process (optimal values of the process variables), and an optimal model (obtained by iterative rebuilding of the manufacturing model). The application of the proposed approach is sampled through a comparative illustration.

Surface roughness plays an essential role in friction surfacing deposition as a smooth substrate surface polishes both consumable and substrate tools, resulting in a lack of deposition. Hence, an attempt is made to investigate the effect of substrate surface roughness while friction surfacing of AA6061-T6 coating on CR01 low carbon steel and its performance is compared through push-off strength. It is revealed that with an increase in substrate surface roughness, more rubbing action occurs between consumable tool and substrate, which results in higher heat generation and reduction in deposition thickness. The grain refinement is observed at the coating region due to dynamic recrystallisation, which results in fine grain microstructure. The substrate with Ra roughness values 1.5-2.5, 5.5-6.5 and 7.5-8.5 µm showed 26, 32 and 45 MPa push-off strength, respectively. Hence, it is inferred that the push-off strength increases substantially with an increase in the substrate surface roughness.

Magnesium-based biodegradable alloys used in medical applications have been intensively researched throughout the years. As is well known, the biodegradability of medical alloys is improved by alloying Mg with biocompatible and non-toxic metals. According to studies, Mg, Zn, and Ca are abundant in the human body and help to the regeneration of bone tissue efficiently and effectively. Due to their biodegradability, magnesium alloys, particularly Mg–Ca–Zn alloys used to manufacture implants, reduce patient stress by eliminating the need for a second surgery. Due to magnesium alloys' similar Young's modulus (41-45 GPa) to that of natural bone, the stress shielding effect can be significantly reduced. The objective of this research is to examine the tribological and mechanical properties of a novel experimental biodegradable alloy composed of magnesium (Mg) and 0.5 wt. % Ca, with variable amounts of zinc (Zn) at 0.5, 1.5, and 3.0 wt. %, with the aim of improve the mechanical characteristics. The microstructure and mechanical characteristics were determined using light microscopy (LM), a CETR UMT-2 Tribometer, and an Instron 34SC-5 instrument. A magnesium solid solution as well as a lamellar Mg2Ca and a MgZn2 intermetallic compound were discovered as a result of this research. The tribological parameters exhibit a decrease in coefficient of friction (COF) with increasing Zn concentration and a little increase in hardness and Young modulus up to 3 wt.%.
