Authors: Asa’d Randa , Hernandez S. , As’ad A. , Molero M. , Matteucci F. , Larsen S. , Chilingarian Igor V. 
Published: April 2022

Abstract
We derive the first detailed chemical abundances of three star clusters in the Large Magellanic Cloud (LMC), NGC 1831 (436 ± 22 Myr), NGC 1856 (350 ± 18 Myr), and [SL63]268 (1230 ± 62 Myr) using integrated-light spectroscopic observations obtained with the Magellan Echelle spectrograph on Magellan Baade telescope. We derive [Fe/H], [Mg/Fe], [Ti/Fe], [Ca/Fe], [Ni/Fe], [Mn/Fe], [Cr/Fe], and [Na/Fe] for the three clusters. Overall, our results match the LMC abundances obtained in the literature as well as those predicted by detailed chemical evolution models. For clusters NGC 1831 and NGC 1856, the [Mg/Fe] ratios appear to be slightly depleted compared with [Ca/Fe] and [Ti/Fe]. This could be hinting at the well-known Mg–Al abundance anti-correlation observed in several Milky Way globular clusters. We note, however, that higher signal-to-noise observations are needed to confirm such a scenario, particularly for NGC 1831. We also find a slightly enhanced integrated-light [Na/Fe] ratio for cluster [SL63]268 compared with those from the LMC field stars, possibly supporting a scenario of intracluster abundance variations. We stress that detailed abundance analysis of individual stars in these LMC clusters is required to confirm the presence or absence of multiple stellar populations.
CHIPS: Complete History of Interaction-powered Supernovae
Authors: Takei Yuki , Tsuna Daichi , Kuriyama Naoto , Ko Takatoshi , Shigeyama Toshikazu 
Published: April 2022

Abstract
We present the public release of the Complete History of Interaction-Powered Supernovae (CHIPS) code, which is suited to model a variety of transients that arise from interaction with a dense circumstellar medium (CSM). Contrary to existing modelings, which mostly attach the CSM by hand, CHIPS self-consistently simulates both the creation of the CSM from mass eruption of massive stars prior to core collapse, and the subsequent supernova light curve. We demonstrate the performance of CHIPS by presenting examples of the density profiles of the CSM and the light curves. We show that the gross light-curve properties of putative interaction-powered transients (e.g., Type IIn supernovae, rapidly evolving transients and recently discovered fast blue optical transients) can be comprehensively explained with the output of CHIPS.
Detection of a Prompt Fast-variable Thermal Component in the Multipulse Short Gamma-Ray Burst 170206A

Published: April 2022

Abstract
We report the detection of a strong thermal component in the short gamma-ray burst 170206A with three intense pulses in its light curves, throughout which the fluxes of this thermal component exhibit fast temporal variability the same as that of the accompanying nonthermal component. The values of the time-resolved low-energy photon index in the nonthermal component are between about −0.79 and −0.16, most of which are harder than the −2/3 expected in the synchrotron emission process. In addition, we found a common evolution between the thermal component and the nonthermal component,

Enchantements et désenchantements dans la formation et utilisation des théories psychanalytiques sur la réalité psychique
Authors: Bolognini Stefano , Adam Elena 
Published: April 2022

Cette réflexion explore la complexité des relations intrapsychiques des analystes avec leurs théories d’élection et leur déclinaison complexe dans le cadre plus général de la communauté et de la littérature psychanalytiques, à travers les vicissitudes historiques réitérées ayant accompagné la formation des groupes, des écoles et les orientations technico-conceptuelles, souvent conflictuelles, au cours des décennies. L’auteur souligne en particulier l’importance des mouvements transférentiels profonds envers les auteurs dont les conceptualisations inspirent tout analyste, par-delà des choix « objectifs » (ou supposés tels). L’intégration plus ou moins harmonieuse des « objets théoriques internes » avec le Moi de travail et le Soi de travail individuels, constitue une tâche évolutive essentielle pour la croissance personnelle et le parcours de formation des analystes contemporains.
Freud et la pulsion de bonheur ( Glückstrieb )
Authors: Kamieniak Jean-Pierre 
Published: April 2022

L’énigme du bonheur s’est posée à Freud avant même la fondation de la psychanalyse, trouvant progressivement sa signification au cours du développement de celle-ci, attachée qu’elle est à l’avènement du sujet et à son devenir pulsionnel, au point que le savant envisagera l’existence d’une « pulsion de bonheur » en 1924, puis offrira au monde six ans plus tard une réflexion magistrale sur les multiples voies et tentatives d’accès à la félicité. Ce sont les aléas et le cheminement de cette construction de la notion de bonheur que le lecteur est invité à emprunter ici.
Vivre dans un monde avec ou sans mémoire du futur
Authors: Goretti Regazzoni Giovanna , Pierrakos Maria 
Published: April 2022

« Un pays sans mémoire n’a pas de futur. » L’auteur suggère que faire du futur l’objet privilégié et affligé de la mémoire – signification peut-être étrangère au titre de la trilogie de Bion – pourrait guider les choix au niveau individuel et collectif, conditionner les politiques et les plans de développement, sauvegarder le territoire et le patrimoine artistique ; et offrir une attention constante à l’écologie de l’esprit, ce bien précieux auquel il semble que l’on ait parfois cessé de penser et que tout semble concourir à endommager.
O Não Reconhecimento dos Sujeitos No Espaço Escolar: Saberes Invisibilizados
Authors: Batista dos Santos Reinaldo , Oliveira Cardeal Janine 
Published: April 2022

Este artigo tem por objetivo compreender e dar visibilidade aos saberes e trajetórias escolares expostas pelos trabalhadores de limpeza que realizam atividades laborais numa universidade pública federal. Selecionamos para este trabalho apenas a memória narrativa escolar de seis trabalhadores. Tal pesquisa aponta para a trama da memória narrativa das trajetórias como “experiências narráveis” (BENJAMIN, 1987). Assim, são nas dobras destas narrativas – memórias nas quais se confundem passado-presente-futuro – que se rompe a pretensão de uma linearidade cronológica, para dar vez e visibilidade àqueles que se (re)inventam em suas histórias, em busca de uma justiça social e, sobretudo, de uma “justiça cognitiva” (SANTOS, 2004).
A Importância de Arlindo Cruz nas Transformações do Samba a partir da Década de 1980
Authors: Dos Santos Meneses João Luís 
Published: April 2022

O samba tocado nos “fundos de quintal” é uma tradição presente na cultura brasileira desde pelo menos o início do século XX, como revela a literatura (LOPES, 1992; SANDRONI, 2001; VIANNA, 2004). Tal prática “sobreviveu” nas favelas cariocas e permaneceu alheia à indústria fonográfica até a “descoberta” de Beth Carvalho e do produtor musical Rildo Hora na década de 1970, o que originou diversas transmutações no samba, sobre as quais este trabalho pretende discutir, especialmente aquelas provenientes do cantor carioca Arlindo Cruz. Sob a perspectiva transdisciplinar, ancorada especialmente em autores como Stuart Hall (2005), Hobsbawn (1997) e Tagg (1999), objetiva-se refletir sobre as seguintes perguntas: quais são as características dessa nova linguagem? Como elas dialogam com o seu tempo histórico? Em outras palavras, pretende-se investigar, analisar e interpretar aspectos sonoros – letra, melodia, harmonia, ritmo e expressão - e extra sonoros - signos e sinais manifestados nos discursos, na idumentária e nos estilos de vida dos músicos - a partir da hipótese de que tais práticas são construções híbridas decorrentes da mundialização, onde as culturas distintas rompem fronteiras e se inter-relacionam criando novas “subculturas”. Tal processo é característico do que Hall (2005) chama de “identidade cultural na pós-modernidade”.

Published: April 2022

PurposeThe objectives of our study were to evaluate the changes in the cross-section area of carotid and femoral arteries caused by fluid loss during haemodialysis (HD) and to determine the direction and amount of these changes.Material and methodsSeventy-four HD patients (28 women and 46 men) were studied. We performed ultrasound exams of the distal common carotid and proximal femoral arteries in each patient before and after a HD session. Recorded exams were analysed using EchoPac software. Arterial cross-section area values were acquired for further analysis.ResultsWe found a statistically significant decrease in arterial systolic cross-section area values after HD sessions (carotid arteries area before HD equalled 0.6731 cm2 and 0.6333 cm2, <i>p</i> = 0.00001 after HD, femoral arteries area before HD equalled 0.8263 cm2 and 0.7635 cm2, <i>p</i> = 0.00001 after HD). The decrease of systolic carotid cross-section area correlated with the amount of fluid lost during HD sessions (correlation coefficient of 0.3122, <i>p</i> = 0.010) and the percentage of the body mass lost during HD (correlation coefficient of 0.3577, <i>p</i> = 0.003). No statistically significant changes were found in the femoral cross-section area.ConclusionsOur findings suggest that the arterial cross-section area may be used in the assessment of response to body fluid loss. We were able to measure changes due to fluid loss during the HD session. The carotid cross-section values decreased after the procedure and correlated with the amount of fluid lost during the HD session.

¿Qué opinan en la posguerra algunos actores influyentes sobre el conflicto interno de los ochenta en El Salvador?
Authors: Romero Rafael 
Published: April 2022

Los principales actores durante, esa sangrienta década incluyen primariamente, al binomio Fuerzas Armadas de El Salvador (FAES)-Gobierno de El Salvador (GOES); al Frente Farabundo Martí para la Liberación Nacional (FMLN); y consecutivas administraciones de los EE. UU. La dupla oficial contó con el apoyo sistemático e incondicional de los EE. UU.; así como de la oligarquía doméstica. Por su parte, el FMLN conto con varias formas de solidaridad internacional, que incluyeron apoyo político-diplomático, atención médica a lisiados de guerra y hasta el suministro de algún armamento militar. Los ‘Acuerdos de Paz’, terminaron con las belicosidades internas; pero no con varias de sus causas. La mayoría de las heridas continúan abiertas; y sin la democracia anhelada. Por eso, es pertinente saber, ¿Qué piensan algunos de esos actores; tres décadas después?

Abstract. Understanding the dynamics of peatland methane (CH4) emissions and quantifying sources of uncertainty in estimating peatland CH4
emissions are critical for mitigating climate change. The relative contributions of CH4 emission pathways through ebullition, plant-mediated
transport, and diffusion, together with their different transport rates and vulnerability to oxidation, determine the quantity of CH4 to be
oxidized before leaving the soil. Notwithstanding their importance, the relative contributions of the emission pathways are highly uncertain. In
particular, the ebullition process is more uncertain and can lead to large uncertainties in modeled CH4 emissions. To improve model
simulations of CH4 emission and its pathways, we evaluated two model structures: (1) the ebullition bubble growth volume threshold approach
(EBG) and (2) the modified ebullition concentration threshold approach (ECT) using CH4 flux and concentration data collected in a peatland
in northern Minnesota, USA. When model parameters were constrained using observed CH4 fluxes, the CH4 emissions simulated by the EBG
approach (RMSE = 0.53) had a better agreement with observations than the ECT approach (RMSE = 0.61). Further, the EBG approach simulated a
smaller contribution from ebullition but more frequent ebullition events than the ECT approach. The EBG approach yielded greatly improved
simulations of pore water CH4 concentrations, especially in the deep soil layers, compared to the ECT approach. When constraining the EBG
model with both CH4 flux and concentration data in model–data fusion, uncertainty of the modeled CH4 concentration profiles was
reduced by 78 % to 86 % in comparison to constraints based on CH4 flux data alone. The improved model capability was attributed to
the well-constrained parameters regulating the CH4 production and emission pathways. Our results suggest that the EBG modeling approach
better characterizes CH4 emission and underlying mechanisms. Moreover, to achieve the best model results both CH4 flux and
concentration data are required to constrain model parameterization.

Authors: ÜNSAL Gürkan , OF Ece , TÜRKAN İrem , BAYRAKDAR İbrahim Şevki , ÇELİK Özer 
Published: April 2022

Aim: The aim of this study is to create a model that enables the detection of dentigerous cysts on panoramic radiographs in order to enable dentistry students to meet and apply artificial intelligence applications.
Methods: E.O. and I.T. who are 5th year students of the faculty of dentistry, detected 36 orthopantomographs whose histopathological examinations were determined as Dentigerous Cyst, and the affected teeth and cystic cavities were segmented using CranioCatch's artificial intelligence supported clinical decision support system software. Since the sizes of the images in the dataset are different from each other, all images were resized as 1024x514 and augmented as vertical flip, horizontal flip and both flips were applied on the train-validation. Within the obtained data set, 200 epochs were trained with PyTorch U-Net with a learning rate of 0.001, train: 112 images (112 labels), val: 16 images (16 labels). With the model created after the segmentations were completed, new dentigerous cyst orthopantomographs were tested and the success of the model was evaluated.
Results: With the model created for the detection of dentigerous cysts, the F1 score (2TP / (2TP+FP+FN)) precision (TP/ (TP+N)) and sensitivity (TP/ (TP+FN)) were found to be 0.67, 0.5 and 1, respectively.
Conclusion: With a CNN approach for the analysis of dentigerous cyst images, the precision has been found to be 0.5 even in a small database. These methods can be improved, and new graduate dentists can gain both experience and save time in the diagnosis of cystic lesions with radiographs.

The aromachology and possibilities of its application in a selected business entity
Authors: Berčík Jakub , Virágh Roderik , Kádeková Zdenka , Budovcová Martina 
Published: April 2022

Aromachology studies the influence of odours on human behaviour and examines the relationship between feelings and emotions. The submitted paper deals with implementing a new marketing communication tool into practice and the possibilities of its use. Our research deals with the use of the human senses in marketing, where we take a closer look at the sense of smell because it has an important position in the human mind and life. It can awaken our memories and create emotions and improve the mood and often unconsciously influence consumer behaviour. The paper is divided into two parts. The first one aims at the theoretical introduction devoted to basic concepts such as aromachology and aroma marketing. This knowledge was subsequently applied directly to the surveyed company in the results part. The research subject is the influence of aromas on the emotional side of consumer behaviour which is influenced by all stimuli around us. Based on the research, we identified the most suitable aroma category that the company could use in the future. We have developed proposals and recommendations that could help increase awareness of a new product in the company's portfolio through unconscious communication at the point of sale, which will bring the gradual implementation of this marketing tool into practice. Two questionnaires were used – the first one aimed to gain basic information about consumers and their consumer behaviour. The second one was realized as a blind review of selected aromas using facial biometrics. Based on both surveys, we can conclude that introducing a specific aroma in the company certainly could influence the sale of a new product, a chocolate cake.
