This project shows the development of an automated exhaust fan for a modern kitchen with an IoT notification system for a better air ventilation system with lower electrical consumption and cheaper installation costs. Utilizing an exhaust fan as the ventilation system will significantly lower the cost of installation and maintenance. The exhaust fan will carry the process of removing hot air from the kitchen so that cooler surrounding temperatures can be achieved. The application of an automated microcontroller system will allow higher energy efficiency for daily cooking appliance usage. Then, the application of the DHT22 temperature sensor as the input for the microcontroller which can detect the precise temperature of the surrounding air. The exhaust fan will automatically turn ON when it detects the surrounding temperature is increased from 33℃. However, a notification will be sent to the user through the Blynk Application when the temperature of the kitchen is increasing and achieved 37℃ while a buzzer will turn ON to alert people in the house. Next, the AC voltage controller will help regulate the speed of the fan according to the input temperature so that more energy can be saved during long daily usage. At the end of this project, the outcome product will become a microcontroller that can be used in various types of households that already have a wall-mounted exhaust fan. Moreover, more users will be able to install this whole ventilation system for their hot kitchen due to low installation and maintenance costs. Lastly, the electrical monthly bill can be reduced.

The human body is protected by an immune system which mainly consists of white blood cells (WBCs). There are five types of white blood cells, and each type will fight certain viruses and bacteria that are encountered in the human body. This defence system helps to maintain human health. Consequently, healthy WBCs keep humans healthy. Abnormality in WBCs can cause harmful viruses or bacterial infections. Leukaemia is a common WBCs disease which affects the production of good cells. Early detection is important for advanced treatment for cancer patient. One of the detection methods is by visual detection of the blood microscopic image since the five types of the WBCs are visually distinctive. In current practice, the pathologist will perform the diagnosis manually which may take time if there are many samples to examine. This procedure can be improved by automating it using a computer aided detection system. This paper studied the deep learning detection model of YOLOv5s and the effect of fusing the Squeeze-Excitation (SE) and Convolutional Block Attention Model (CBAM) into the YOLOv5s. It was performed on the four types of the WBCs, eosinophil, lymphocyte, monocyte, and the neutrophil taken from a public dataset. Based on the findings, the proposed method of YOLOv5s-SE, YOLOv5s-CBAM, and YOLOv5s-SE-CBAM produced overall accuracy of 99.5%, 99.5% and 99.4% mAP value and the performance are at par with the deeper model YOLOv5m with 65.8% of a smaller number of hyperparameters.

The circular economy was created to convert waste resources into economic products by implementing various strategies, two of which are: using materials from renewable sources and producing biodegradable products. The aim of this research is to manufacture polylactid acid (PLA) which is usually made from fermented plant starch, and a mixture of polycaprolactone (PCL), a biodegradable polyester, to investigate its potential use as a substitute for oil-based commodity plastics. The PLA/PCL mixes were mixed in batches using a lab-scale internal mixer and then printed. The mechanical strength of the resulting bioplastic was tested using the UTM d638 tool. It has been found that incorporating PCL into the PLA matrix can produce materials with tensile strengths ranging from 8.67 to 44.48 mPa. The incorporation of PCL significantly increases the toughness of PLA, increasing the energy required to fracture the specimen. Based on the results of GC-MS compounds like Beta elemene, Caryophyllene, Methanodrostonole, Alpha humulene, and Gamma gurjenene from jamblang seeds have good antioxidant activity. The addition of active compounds in the matrix must be considered in the study of the durability and stability of the PLA-PCL packaging film. When the active ingredient was added more than 7%, the tensile strength decreased drastically due to the only interaction between the active agent in the form of catechin and chitosan. Overall, the obtained PLA/PCL blends were found to be a strong and environmentally friendly alternative to oil-based commodity materials.

Published: July 2024

Purpose: To evaluate the prevalence and clinical characteristics of dry eye disease (DED) among individuals with type 2 diabetes in a community-based setting. Additionally, the study aimed to identify factors associated with the presence of DED in this population.  Methods: A total of 136 randomly selected patients diagnosed with type 2 diabetes participated in the study, undergoing comprehensive ophthalmic evaluations. These evaluations included corneal sensitivity testing, tear film break-up time (BUT) assessment, the Schirmer I test, and fundus photography. The severity of diabetic retinopathy (DR) was graded according to the International Severity Scale.  Results: Among the 136 subjects, 23 (17.1%) were diagnosed with DED. There were significant associations between DED and higher blood glucose levels (P < 0.001) as well as elevated glycosylated hemoglobin (HbA1c) levels (P < 0.001).  Conclusions: These findings highlight the importance of incorporating dry eye assessments into the routine screening protocol for diabetic patients. The observed prevalence of DED at 17.1% in this cohort is lower than the rates reported in other studies. Importantly, individuals with diabetes who have poorer metabolic control are at a higher risk of developing DED.

TOWARDS A COMPREHENSIVE EVALUATION OF DECENTRALIZATION: A MULTIDIMENSIONAL INSIGHT OF OECD COUNTRIES
Authors: Poniatowicz Marzanna , Konopka Paweł , Piekutowska Agnieszka
Published: July 2024

The present paper introduces a novel methodology for analyzing decentralization across three dimensions: political, administrative, and fiscal. Considering the challenges in determining the degree of decentralization, we have constructed synthetic measures for assessing political (MPD), administrative (MAD), and fiscal (MFD) decentralization employing the TOPSIS method (Technique for Order Preference by Similarity to an Ideal Solution). The use of this method allowed the creation of a linear rank of OECD countries. Furthermore, on the basis of constructed synthetic measures and utilizing the k-means clustering method, we also constructed a non-linear grouping of those countries. This approach enabled us to achieve the final objective of our research, the revelation of varied interrelationships among the different dimensions of decentralization in selected OECD countries. The combined application of the TOPSIS and the k-means methods enhances the methodology for analyzing decentralization by offering a multidimensional perspective. Given the potential repercussions of negative outcomes, such as overt or covert centralization, the findings of our study could turn out to be of significant relevance.

Published: July 2024

Discovering new actively accreting protoplanets is crucial to answering open questions about planet formation. However, identifying such planets at orbital distances where they are expected to be abundant is extremely challenging, both due to the technical requirements and large distances to star-forming regions. Here we use the kernel phase interferometry (KPI) technique to search for companions around the ∼6 and ∼8 Myr old Herbig Ae stars MWC 758 and MWC 480. KPI is a data analysis technique that is sensitive to moderate asymmetries, arising from, e.g., a circumstellar disk or companions with contrasts of up to 6–8 mag, at separations down to and even below the classical Rayleigh diffraction limit (∼1.2λ/D). Using the high-spectral-resolution K-band mode of the SCExAO/CHARIS integral field spectrograph, we search for both excess Br-γ line emission and continuum emission from companions around MWC 480 and MWC 758. We are able to set limits on the presence of rapidly accreting protoplanets and brown dwarfs between 4 and 16 au, well interior to those of previous studies. In Br-γ, we set limits on excess line emission equivalent to accretion rates ranging from

We present an overview of the LBT Imaging of Galactic Halos and Tidal Structures survey, which currently includes 25 nearby galaxies that are on average ∼1 mag fainter than the Milky Way, and a catalog of 54 low central surface brightness (24 < μ
0,g
/mag arcsec−2 < 28) satellite galaxy candidates, most of which were previously uncatalogued. The depth of the imaging exceeds the full 10 yr depth of the Rubin Observatory’s Legacy Survey of Space and Time. We find, after applying completeness corrections, rising numbers of candidate satellites as we approach the limiting luminosity (M

r
∼ −8 mag) and central surface brightness (μ
0,g
∼ 28 mag arcsec−2). Over the parameter range we explore, each host galaxy (excluding those that are in overdense regions, apparently groups) has nearly four such candidate satellites to a projected radius of ∼100 kpc. These objects are mostly just at or beyond the reach of spectroscopy unless they are H i rich or have ongoing star formation. We identify three, possibly four, ultra-diffuse satellite galaxies (effective radius >1.5 kpc). This incidence rate falls within expectations of the extrapolation of the published relationship between the number of ultra-diffuse satellite galaxies and host halo mass. Last, we visually identify 12 candidate satellites that host a nuclear star cluster (NSC). The NSC occupation fraction for the sample (12/54) matches that published for satellites of early-type galaxies, suggesting that the parent’s morphological type plays at most a limited role in determining the NSC occupation fraction.

Published: July 2024

We present statistics of z ∼ 6–9 galaxy outflows indicated by spatially extended gas emission and broad lines. With a total of 61 spectroscopically confirmed galaxies at z ∼ 6–9 in the JWST CEERS, GLASS, and ERO data, we find four galaxies with [O iii] + Hβ ionized gas emission significantly extended beyond the kiloparsec-scale stellar components on the basis of the emission line images constructed by the subtraction of NIRCam broadband (line on/off-band) images. By comparison with low-z galaxies, the fraction of galaxies with spatially extended gas, 4/18, at z ∼ 6–9 is an order of magnitude higher than that at z ∼ 0–1, which can be explained by events triggered by frequent major mergers at high redshift. We also investigate medium- and high-resolution NIRSpec spectra of 30 galaxies at z ∼ 6–9, and identify five galaxies with broad (140−800 km s−1) lines in the [O iii] forbidden line emission, suggestive of galaxy outflows. One galaxy at z = 6.38 shows both spatially extended gas emission and the broad lines, while none of the galaxies with spatially extended gas emission or broad lines present a clear signature of active galactic nuclei (AGN) in either the line diagnostics or type 1 AGN line broadening (>1000 km s−1), which suggests that outflows are mainly driven by stellar feedback. The existence of galaxies with/without spatially extended gas emission or broad lines may be explained by different viewing angles toward outflows or the fact that these are galaxies in the early, late, or post phases of galaxy outflows at high redshift, where relatively large fractions of such galaxies indicate longer-duration and/or more frequent outflows at early cosmic epochs.
Effect of Magnetic Diffusion in the Chromosphere on the Solar Wind
Authors: Matsuoka Masato , Suzuki Takeru K. , Tokuno Takato , Kakiuchi Kensuke
Published: July 2024

We investigate nonideal magnetohydrodynamical (MHD) effects in the chromosphere on the solar wind by performing MHD simulations for Alfvén-wave-driven winds, explicitly including ohmic and ambipolar diffusion. We find that MHD waves are significantly damped in the chromosphere by ambipolar diffusion so that the Alfvénic Poynting flux that reaches the corona is substantially reduced. As a result, the coronal temperature and the mass-loss rate of the solar wind are considerably reduced, compared with those obtained from an ideal MHD case, which is indicative of the great importance of the nonideal MHD effects in the solar atmosphere. However, the temperature and the mass-loss rate are recovered by a small increase in the convection-originated velocity perturbation at the photosphere because of the sensitive dependence of the ambipolar diffusion and reflection of Alfvén waves on the physical properties of the chromosphere. We also find that density perturbations in the corona are reduced by the ambipolar diffusion of Alfvén waves in the chromosphere because the nonlinear generation of compressible perturbations is suppressed.
The Impact of the Explicit Representation of Convection on the Climate of a Tidally Locked Planet in Global Stretched-mesh Simulations

Published: July 2024

Convective processes are crucial in shaping exoplanetary atmospheres but are computationally expensive to simulate directly. A novel technique of simulating moist convection on tidally locked exoplanets is to use a global 3D model with a stretched mesh. This allows us to locally refine the model resolution to 4.7 km and resolve fine-scale convective processes without relying on parameterizations. We explore the impact of mesh stretching on the climate of a slowly rotating TRAPPIST-1e-like planet, assuming it is 1:1 tidally locked. In the stretched-mesh simulation with explicit convection, the climate is 5 K colder and 25% drier than that in the simulations with parameterized convection(with both stretched and quasi-uniform meshes). This is due to the increased cloud reflectivity—because of an increase in low-level cloudiness—and exacerbated by the diminished greenhouse effect due to less water vapor. At the same time, our stretched-mesh simulations reproduce the key characteristics of the global climate of tidally locked rocky exoplanets, without any noticeable numerical artifacts. Our methodology opens an exciting and computationally feasible avenue for improving our understanding of 3D mixing in exoplanetary atmospheres. Our study also demonstrates the feasibility of a global stretched-mesh configuration for LFRic-Atmosphere, the next-generation Met Office climate and weather model.
Very Long Baseline Interferometry Detection of an Active Radio Source Potentially Driving 100 kpc Scale Emission in the Ultraluminous Infrared Galaxy IRAS F01004–2237
Authors: Hayashi Takayuki J. , Hagiwara Yoshiaki , Imanishi Masatoshi
Published: July 2024

The nearby ultraluminous infrared galaxy (ULIRG) IRAS F01004−2237 exhibits 100 kpc scale continuum emission at radio wavelengths. The absence of extended X-ray emission in IRAS F01004−2237 has suggested an active galactic nucleus (AGN) origin for the extended radio emission, whose properties and role in merging systems still need to be better understood. We present the results of multifrequency observations of IRAS F01004−2237 conducted by the Very Long Baseline Array at 2.3 and 8.4 GHz. Compact 8.4 GHz continuum emission was detected on a 1 pc scale in the nuclear region with an intrinsic brightness temperature of 108.1 K suggesting that the radio source originated from an AGN, potentially driving the extended emission. In contrast, no significant emission was observed at 2.3 GHz, indicating the presence of low-frequency absorption. This absorption cannot be attributed solely to synchrotron self-absorption; alternatively, free–free absorption due to thermal plasma is mainly at work in the spectrum. From combined perspectives, including mid-infrared and X-ray data, the AGN is obscured in a dense environment. The kinetic power of the nonthermal jet, as inferred from the extended emission, can play a more important role in dispersing the surrounding medium than the thermal outflow in IRAS F01004−2237. These findings hint that jet activities in ULIRGs may contribute to AGN feedback during galaxy evolution induced by merger events.

Published: July 2024

It is generally hard to put robust constraints on progenitor masses of supernovae and supernova remnants (SNRs) observationally, while they offer tantalizing clues to understanding explosion mechanisms and mass distribution. Our recent study suggests that “shell merger,” which is theoretically expected for stellar evolution, can appreciably affect the final yields of intermediate-mass elements (IMEs; such as Ne, Mg, and Si). In light of this, here we report the results of the X-ray spectral analysis of a Galactic SNR G359.0−0.9, whose abundance pattern may possibly be anomalous according to a previous study. Our spectroscopy using all the available data taken with XMM-Newton reveals that this remnant is classified as a Mg-rich SNR because of its high Mg-to-Ne ratio (

) and conclude that the result cannot be explained without the shell merger. By comparing the observation with theoretical calculations, we prefer the so-called Ne-burning shell intrusion and in this case, the progenitor mass M

⊙. We confirm the result also with our new molecular-line observations with the Nobeyama 45 m telescope: G359.0−0.9 is located in the Scutum–Centaurus arm (2.66–2.94 kpc) and in this case, the resultant total ejecta mass ∼6.8M
⊙ is indeed consistent with the above estimate. Our method using mass ratios of IMEs presented in this paper will become useful to distinguish the type of shell merger, the Ne-burning shell intrusion, and the O-burning shell merger, for future SNR studies.

In this paper, we describe Ixeridium nujiangense, a novel species identified in southwestern Yunnan, China. Two populations have been found along the riverbanks of the Nujiang River in Yongde and Zhenkang Counties. Morphologically, I. nujiangense is most similar to the recently described I. malingheense, but it can be readily distinguished by its mostly divided basal leaves, narrower non-clasping cauline leaves, notably shorter corolla tube, pale brown anthers, and considerably longer beak of achenes.

Ce texte présente la nouvelle de Melville, Bartleby , comme une piste qui nous est offerte, face à une personne ou un système qui assujettit l’individu, pour déjouer les figures du mal que sont la coercition, l’oppression ou la manipulation. Il nous montre la puissance d’un tout petit énoncé –  « Je préférerais ne pas »  – qui désamorce les modes habituels de penser et d’agir les rapports d’autorité. Au-delà du combat et de la fuite, il opère une mystérieuse désorganisation des forces en présence dont nous présentons ici un des aspects et que nous illustrons par une vignette clinique.

Trois vignettes cliniques tentent de montrer, dans un premier temps, différents types d’introjections malsaines et d’illustrer ensuite les mouvements de désobéissance auxquels la thérapeute a eu l’impression d’assister en séance, les siens compris. Tous ces mouvements trouvent leur source dans un point d’appui intérieur qu’elle tente de décrire avec un œil phénoménologique.

Si l’intégration et la réception de cette approche dans les politiques nationales de soutien à la parentalité sont connues, ce n’est pas le cas des critiques dont ces modèles et leurs évolutions ont fait l’objet. En mobilisant le concept d’histoire croisée, cet article 2 tente d’identifier les influences de différents modèles de politiques de soutien à la parentalité sur les deux principales communautés belges. À partir de la littérature sur le Royaume-Uni (modèle d’encadrement fort) et la France (orientation plus critique), il étudie les évolutions des politiques belges de soutien dans les communautés flamande et française ainsi que leurs particularités entre 1990 et 2020. À partir des sources normatives des politiques familiales, des orientations institutionnelles et de la littérature critique issue du monde académique, cette analyse montre le développement d’un modèle belge complexe et hybride, impossible à unifier sous une même orientation, ainsi que la richesse et la diversité de l’intégration du concept de parentalité positive.
La phénoménologie de la maternité en France
Authors: Chabanel Perrine
Published: July 2024

L’expression « mère porteuse », utilisée dans les discours institutionnels et médiatiques pour désigner la femme qui porte l’enfant dans le cadre d’une gestation pour autrui (GPA), reflète le modèle français de filiation maternelle biologique, associant la mère à l’accouchement. Cette étude analyse des avis du Comité consultatif national d’éthique (CCNE) depuis sa création en 1984, et des terminologies employées entre 1997 et 2023 par les quotidiens Libération et Le Figaro pour saisir la valeur axiologique de l’expression et son rôle dans la perception de la GPA en France. Les éléments de sociolinguistique mobilisés dans cet article démontrent que le choix politique des mots contribue à maintenir la prééminence de la maternité biologique.
Is crypto legitimate? Study on the relationship between legitimacy and public engagement on crypto market in Indonesia
Authors: Almahendra Rangga , Okta Viyani Ari , Nabawi Muhammad
Published: July 2024

Purpose: In recent years, the development of the crypto market has grown exponentially compared to other investment assets. Using the lens of institutional entrepreneurship theory, our research seeks to understand the antecedents of public engagement on crypto market in Indonesia.Design/methodology/approach: To capture this phenomenon, we use institutional and legitimacy theories to explain how social constructs toward cryptocurrency can be formed and accepted by society. Based on the survey of 213 individuals actively engaging in the crypto market, we confirm that public engagement in the crypto market is associated with three different types of legitimacyFindings: The main contribution of this research is that it shows that normative and cognitive legitimacies play a big role in public engagement in the crypto market. This study also found that, in general, individuals engaged in crypto are individuals who only focus on personal gain. They can engage with the crypto market if their personal goals are met.Research limitations/implications: This research is only carried out within the geographical boundaries of Indonesia. It is imperative to conduct investigations in various contexts in order to comprehend how diverse cultural contexts can potentially impact public engagement in the crypto market. Practical implications: This study provides support for the notion that public engagement in the crypto market is correlated with different levels of legitimacy.  The results of this study show that public participation in the crypto market is significantly influenced by normative and cognitive legitimacies.Social implications: This research can be helpful for policymakers and industries able to consider the institutional development of crypto ecosystems and will generate fresh insight into our understanding of the nature of legitimacy-seeking behavior among cryptocurrency adoptersOriginality/value: We propose a new mechanism explaining how institutional frameworks could help explain the emergence of public engagement on Crypto Market.
OpenLabs Security Laboratory - The Online Security Experiment Platform
Authors: Zackrisson Johan , Svahnberg Charlie
Published: July 2024

For experiments to be reproducible, it is important to have a known and controlled environment. This requires isolation from the surroundings. For security experiments, e.g. with hostile software, this is even more important as the experiment can affect the environment in adverse ways. In a normal campus laboratory, isolation can be achieved by network separation. For an online environment, where remote control is essential, separation and isolation are still needed, and therefore the security implications must be considered.
In this paper, a way to enable remote experiments is described, where users are given full control over the computer installation. By automating the install procedure and dynamically creating isolated experiment networks, remote users are provided with the tools needed to do experiments in a reproducible and secure environment.

An Interactive Web-based Learning System for Assisting Machining Technology Education
Authors: Liu Chi-Chia , Jou Min
Published: July 2024

The key technique of manufacturing methods is machining. The degree of technique of machining directly affects the quality of the product. Therefore, the machining technique is of primary importance in promoting student practice ability during the training process. Currently, practical training is applied in shop floor to discipline studentâ??s practice ability. Much time and cost are used to teach these techniques. Particularly, computerized machines are continuously increasing in use. The development of educating engineers on computerized machines becomes much more difficult than with traditional machines. This is because of the limitation of the extremely expensive cost of teaching. The quality and quantity of teaching cannot always be promoted in this respect. The traditional teaching methods can not respond well to the needs of the future. Therefore, this research aims to the following topics;
(1).Propose the teaching strategies for the students to learning machining processing planning through web-based learning system.
(2).Establish on-line teaching material for the computer-aided manufacturing courses including CNC coding method, CNC simulation.
(3).Develop the virtual machining laboratory to bring the machining practical training to web-based learning system.
(4).Integrate multi-media and virtual laboratory in the developed e-learning web-based system to enhance the effectiveness of machining education through web-based system.
Back to Analog. Printing Digital Editions for Data Quality.
Authors: Kupreyev Maxim
Published: July 2024

This article discusses the challenges of printing TEI XML data sets, and highlights a useful diagnostic value of PDF export for data quality. PDF output, indeed, renders only a part of the encoded information, but it can expose problems pertaining to the semantic accuracy and consistency, syntactic compliance, and completeness of the data. The uncovered problems are presented as possessing three dimensions: internal (the compliance of XML code with data models and schemata), external (the consistency of the print output in rendering the original), and contextual (arising from the interaction of XML with the transformation scenarios). These dimensions help to provide the definition of an error in the context of scholarly digital editions—both retro-digitized and originally digital. The article examines the extended skill set required of quality assurance specialists in social sciences and humanities (SSH) as compared to their industrial counterparts. It also places PDF production within the Agile testing framework, which aims to capture and eliminate defects in the early stages of product development.
Pétrarquisme(s) ? enquête sur une catégorie littéraire européenne
Authors: Ferrer Véronique
Published: July 2024

En guise d’introduction, la première contribution propose une brève synthèse sur l’histoire du pétrarquisme européen aux xvie et xviie siècles – avec une attention particulière pour le cas français – en interrogeant le sens de la catégorie et la réalité plurielle que désigne le mot inventé au xixe siècle. Dans un premier temps, une enquête historiographique permet de suivre l’élaboration conceptuelle de la catégorie pour tenter de dégager une définition convergente. Dans un second temps, une approche géo-historique du xve au xviie siècle, de l’Italie vers l’Europe et vers la France en particulier, permet de comprendre son expansion géographique et sa transformation d’activité littéraire en phénomène culturel.
I diversi volti della lirica italiana del Cinquecento. Appunti su Petrarchismo e rappresentazione del sé
Authors: Tomasi Franco
Published: July 2024

En s’appuyant sur les études critiques de ces cinquante dernières années sur le pétrarquisme italien, l’article s’attache à démontrer l’importance capitale des expériences poétiques menées durant les trois premières décennies du xvie siècle. Leur ambition de proposer un langage lyrique coercitif, classique par son style, mais capable d’exprimer une subjectivité profonde, apparaît tangible non seulement à travers le nombre croissant de livres d’auteurs autour des années 1530 mais aussi dans les manières de lire et d’interpréter Pétrarque, à partir surtout du commentaire d’Alessandro Vellutello (1528). Cette conjoncture « littéraire » a pour effet, d’une part de transformer la poésie lyrique en code linguistique et stylistique partagé, d’autre part d’offrir les conditions d’une expression plurielle d’expériences singulières.
Les pétrarquismes de la Renaissance anglaise : histoire et enjeux historiographiques
Authors: Vuillemin Rémi
Published: July 2024

Cet article propose une courte histoire du pétrarquisme anglais de la Renaissance, au sens le plus strict du terme : il ne prend donc en compte que la réception, l’imitation et la traduction du Rerum Vulgarium Fragmenta pétrarquéen. On peut considérer que l’impact de cette œuvre se fait sentir, parfois à basse intensité, de Chaucer à Milton ; la période la plus pertinente reste cependant la deuxième moitié du xvie siècle. À cette époque, l’Angleterre connaît un pétrarquisme au second degré, à travers la médiation, d’une part, des strambottistes italiens (au premier rang desquels figure Serafino Aquilano), d’autre part, des pétrarquistes français dans les dernières décennies du siècle. On insiste ici sur la nécessité de se départir d’une conception du pétrarquisme qui se limite à le voir comme objet de parodie, pour favoriser une perception de la complexité historique de la circulation et de l’adaptation de la poétique pétrarquiste. Il est notamment impossible, dans le contexte de l’Angleterre protestante, de séparer trop strictement un pétrarquisme profane et un pétrarquisme spirituel, tant ces deux traditions sont entrelacées. C’est donc probablement dans l’examen croisé de ses multiples avatars que se situe l’avenir des études sur le pétrarquisme anglais.
Retour en Avignon. Le rapatriement de Laure chez Vasquin Philieul
Authors: Tinguely Frédéric
Published: July 2024

Cet article étudie dans une perspective « mythographique » la première grande traduction française des Rerum Vulgarium Fragmenta de Pétrarque, publiée entre 1548 et 1555 par Vasquin Philieul. Plutôt que de s’intéresser à la traduction elle-même, il examine les « arguments » que le lettré de Carpentras insère entre les poèmes et qui contribuent à narrativiser l’œuvre, à prolonger et à infléchir le récit déjà mythique du grand amour provençal. Les divergences avec le célèbre commentaire d’Alessandro Vellutello, mais aussi certaines convergences avec le mythe de la découverte du tombeau de Laure par Maurice Scève, montrent que Philieul entend servir la politique culturelle de la couronne française tout en revendiquant un ancrage plus spécifique, en Avignon et dans le Comtat Venaissin.
Muer le vice ? L’art de pétrarquiser selon Maurice Scève et Pernette du Guillet
Authors: Hunkeler Thomas
Published: July 2024

Cet article aborde la question du pétrarquisme en comparant le traitement de l’intertexte pétrarquien par Pernette du Guillet à celui de son prétendu « maître » Maurice Scève. Deux postures poétiques peuvent ainsi être distinguées : celle, scévienne, qui soumet l’imitation du « Thuscan Apollo » à l’impératif de s’imposer lui-même comme un nouveau Pétrarque ; et celle de Pernette qui s’insère plus directement dans la tradition pétrarquiste tout en se mettant au service de la promotion de Scève.
