Radial Distribution of Electron Quasi-thermal Noise in the Inner Heliosphere
Authors: Li 李 Yi-Lun 逸伦 , Chen 陈 Ling 玲 , Wu 吴 De-Jin 德金
Published: November 2024

The electron population in the solar wind plasma can be described with three different components: a core, a halo, and a magnetic field aligned strahl. The electron quasi-thermal noise (QTN) is investigated by using an electron population model consisting of a core with a Maxwellian distribution and a halo with a kappa distribution, based on the empirical equations for electron density and temperature and the index for the kappa halo. The power spectra of the electron QTN are calculated at different heliocentric radial distances from 10 to 200 R

s
. The dependence of the QTN spectrum and effective Debye length on model parameters, including the ratio of the halo to the core for the density and temperature, the kappa index, and the antenna length, is further discussed. The results show that the electron QTN spectrum consists of a plateau in the low-frequency band f < f

pt
, a peak at the total plasma frequency f

pt
, and a rapidly decreasing part in the high-frequency band f > f

pt
. The QTN peak and plateau level continuously decrease as the radial distance increases, with the peak’s shape changing due to the variation of the kappa index. Although the model parameters are variable, the QTN plateau level presents less than an order of change with these parameters changing greatly, and only a monotonic change of the plateau is shown when the parameters are close to the practical situation. The results can provide a reference for future deep-space exploration in the inner heliosphere, and also for the design of detectors.

Published: November 2024

Nongravitational accelerations in the absence of observed activity have recently been identified on near-Earth objects (NEOs), opening the question of the prevalence of anisotropic mass loss in the near-Earth environment. Motivated by the necessity of nongravitational accelerations to identify 2010 VL65 and 2021 UA12 as a single object, we investigate the problem of linking separate apparitions in the presence of nongravitational perturbations. We find that nongravitational accelerations on the order of 1 × 10–9 au day−2 can lead to a change in plane-of-sky positions of ∼1 × 103 arcsec between apparitions. Moreover, we inject synthetic tracklets of hypothetical nongravitationally accelerating NEOs into the Minor Planet Center orbit identification algorithms. We find that at large nongravitational accelerations (∣A

i
∣ ≥ 1 × 10−8 au day−2) these algorithms fail to link a significant fraction of these tracklets. We further show that if orbits can be determined for both apparitions, the tracklets will be linked regardless of nongravitational accelerations, although they may be linked to multiple objects. In order to aid in the identification and linkage of nongravitationally accelerating objects, we propose and test a new methodology to search for unlinked pairs. When applied to the current census of NEOs, we recover the previously identified case but identify no new linkages. We conclude that current linking algorithms are generally robust to nongravitational accelerations, but objects with large nongravitational accelerations may potentially be missed. While current algorithms are well-positioned for the anticipated increase in the census population from future survey missions, it may be possible to find objects with large nongravitational accelerations hidden in isolated tracklet pairs.
Stellar Bars Form Dark Matter Counterparts in TNG50
Authors: Ash Neil , Valluri Monica , Chen Yingtian , Bell Eric F.
Published: November 2024

Dark matter (DM) bars that shadow stellar bars have been previously shown to form in idealized simulations of isolated disk galaxies, but have yet to be studied in a fully cosmological context. In this work, we analyze a population of disk galaxies within the TNG50 simulation to determine the characteristics of their dark bars. We estimate bar strength and orientation using both the in-plane Fourier A
2 density moments and the quadrupolar coefficients of the spherical harmonic basis function expansions of the density. We additionally present two novel methods for measuring the bar pattern speed Ω
p
and rotation axis orientation using these coefficients, and apply them to one sample galaxy located in a TNG50 subbox. Consistent with isolated simulations, DM bars are shorter than their stellar counterparts and are 75% weaker in A
2. DM bars dominate the shape of the inner halo potential and are apparent in the time series of quadrupolar coefficients. In our selected subbox galaxy, the stellar and dark bars remain co-aligned throughout the last 8 Gyr and have identical Ω
p
. Pattern speed Ω
p
evolves considerably over the last 8 Gyr, consistent with torques on the bars due to dynamical friction and gas accretion, and is seen to increase following a merger at t

lb
= 1.5 Gyr. Rather than remaining static in time, the bar rotation axis displays both precession and nutation possibly caused by torques outside the plane of rotation. We find that the shape of the stellar and DM mass distributions are tightly correlated with Ω

Published: November 2024

We present the first LOFAR image of the center of M31 at a frequency of 150 MHz. We clearly detect three supernova remnants, which, along with archival VLA data at 3 GHz and other published radio and X-ray data, allows us to characterize them in detail. Our observations also allow us to obtain upper limits of the historical SN 1885A, which is undetected even at a low frequency of 150 MHz. From analytical modeling, we find that SN 1885A will stay in its free-expansion phase for at least another couple of centuries. We find an upper limit of n
H ≲ 0.04 cm−3 for the interstellar medium of SN 1885A, and that the SN ejecta density is not shallower than ∝r
−9 (on average). From the 2.6σ tentative detection in X-ray, our analysis shows that nonthermal emission is expected to dominate the SN 1885A emission. Comparing our results with those on G1.9+0.3, we find that it is likely that the asymmetries in G1.9+0.3 make it a more efficient radio and X-ray emitter than SN 1885A. For Braun 80, 95, and 101, the other remnants in this region, we estimate ages of 5200, 8100, and 13,100 yr, and shock speeds of 1150, 880, and 660 km s−1, respectively. Based on this, the supernova rate in the central 0.5 kpc × 0.6 kpc of M31 is at least one per ∼3000 yr. We estimate radio spectral indices of −0.66 ± 0.05, −0.37 ± 0.03, and −0.50 ± 0.03 for the remnants, respectively, which match fairly well with previous studies.

Published: November 2024

The magnetic orientation of coronal mass ejections (CMEs) is of great importance to understand their space weather effects. Although plenty of evidence suggests that CMEs can undergo significant rotation during the early phases of evolution in the solar corona, there are few reports that CMEs rotate in the interplanetary space. In this work, we use multispacecraft observations and a numerical simulation starting from the lower corona close to the solar surface to understand the CME event on 2021 December 4, with an emphatic investigation of its rotation. This event is observed as a partial halo CME from the back side of the Sun by coronagraphs and reaches the BepiColombo spacecraft and the Mars Atmosphere and Volatile EvolutioN/Tianwen-1 as a magnetic flux-rope-like structure. The simulation discloses that in the solar corona the CME is approximately a translational motion, while the interplanetary propagation process evidences a gradual change of axis orientation of the CME’s flux-rope-like structure. It is also found that the downside and the right flank of the CME moves with the fast solar wind, and the upside does in the slow-speed stream. The different parts of the CME with different speeds generate the nonidentical displacements of its magnetic structure, resulting in the rotation of the CME in the interplanetary space. Furthermore, at the right flank of the CME exists a corotating interaction region, which makes the orientation of the CME alter and also deviates from its route due to the CME. These results provide new insight into interpreting CMEs’ dynamics and structures during their traveling through the heliosphere.
Model-independent Calibration for Sound Horizon: Combining Observations of Supernovae and Baryon Acoustic Oscillation Measurements
Authors: Liu Tonghua , Zhong Xinyi , Biesiada Marek , Wang Jieci
Published: November 2024

The sound horizon scale is a key theoretical prediction of the cosmological model that depends on the speed of sound in the baryon-photon fluid and the rate of expansion of the early Universe, before matter and radiation decoupled. Baryon acoustic oscillations (BAOs) offer the direct measurement of this important scale imprinted in the distribution of galaxies. We propose a new model-independent method to calibrate the sound horizon

Authors: Kosturek Robert , Torzewski Janusz , Wachowski Marcin , Grzelak Krzysztof , Śnieżek Lucjan
Published: November 2024

In this paper, authors reported selected problems in friction stir welding (FSW) of 5 mm-thick AA7075-T651 and 3 mm-thick Ti6Al4V. The investigation involved macro and micro-structure analysis and mechanical testing. The welded joints of Ti6Al4V were characterized by the presence of backing plate steel fragments and tungsten particles in the bottom part of the stir zone (SZ) and thermo-mechanically affected zone (TMAZ), which resulted in a relatively low value of joint efficiency (60 %). The investigation on AA7075-T651 was concerned with high-speed FSW (HSFSW) using the MX Triflute tool. In all cases, defective welded joints have been obtained (incomplete root penetration, voids in the SZ) with the best result of joint efficiency of about 59 %.

In this paper, we present our system called Smart Food and Restaurant Advisor based on nutritional needs and user profiling (SFRA); a multi-criteria food and restaurant recommendation system designed to prioritize personalized and health-conscious selections. This system uses user profiling to offer customized recommendations that cater to individual preferences, requirements, and geographic locations. Our primary objective is to enhance users’ decision-making processes by promoting healthier and more refined lifestyle choices. The results of the proposed system demonstrate that it is well-suited for promoting a healthier lifestyle while offering comprehensive coverage of users’ practices and preferences.
Growth characteristics, redox potential changes and proton motive force generation in Thermus scotoductus K1 during growth on various carbon sources
Authors: Petrosyan Hripsime , Trchounian Karen
Published: November 2024

The extremophile microorganism Thermus scotoductus primarily exhibits aerobic metabolism, though some strains are capable of anaerobic growth, utilizing diverse electron acceptors. We focused on the T. scotoductus K1 strain, exploring its aerobic growth and metabolism, responses to various carbon sources, and characterization of its bioenergetic and physiological properties. The strain grew on different carbon sources, depending on their concentration and the medium's pH, demonstrating adaptability to acidic environments (pH 6.0). It was shown that 4 g L−1 glucose inhibited the specific growth rate by approximately 4.8-fold and 5.6-fold compared to 1 g L−1 glucose at pH 8.5 and pH 6.0, respectively. However, this inhibition was not observed in the presence of fructose, galactose, lactose, and starch. Extracellular and intracellular pH variations were mainly alkalifying during growth. At pH 6.0, the membrane potential (ΔΨ) was lower for all carbon sources compared to pH 8.5. The proton motive force (Δp) was lower only during growth on lactose due to the difference in the transmembrane proton gradient (ΔpH). Moreover, at pH 6.0 during growth on lactose, a positive Δp was detected, indicating the cells' ability to employ a unique energy-conserving strategy. Taken together, these findings concluded that Thermus scotoductus K1 exhibits different growth and bioenergetic properties depending on the carbon source, which can be useful for biotechnological applications. These findings offer valuable insights into how bacterial cells function under high-temperature conditions, which is essential for applying bioenergetics knowledge in future biotechnological advancements.
De reencuentros y emociones. La Barcelona del retorno en el fondo fotográfico del escritor Pere Calders. 1962-1992
Authors: Lucci Marcela
Published: November 2024

A partir del marco teórico-metodológico de la historia emocional, efectuamos una contribución original a los estudios sobre el exilio republicano español en México. Analizamos un caso testigo de la diáspora catalana que buscó refugio en tierras mexicanas durante el Franquismo y atendemos al anhelo y la plasmación del retorno a Barcelona del escritor Pere Calders, en 1962. Para ello, nos centraremos en las fotografías de su archivo personal, depositado en la Biblioteca d’Humanitats de la Universitat Autònoma de Barcelona (BH-UAB). Esta elección permite examinar su experiencia exiliar, que apenas ha sido abordada por la ciencia histórica y, desde el examen de las imágenes, integrarla a la historiografía sobre movimientos contemporáneos de población entre España y América. De esta manera, efectuamos un seguimiento visual del derrotero vital de Calders, para ahondar en las emociones que jalonaron la etapa final de su exilio: el reencuentro con su entorno familiar y con el mundo intelectual y profesional barcelonés de la última época de la dictadura franquista y de la Transición española.
La construction de la nouvelle capitale politique du Burundi à Gitega : aménagement urbain, discours sur la ville et « emblématisation »
Authors: Pasini Jérémy , Ngiye Érasme , Gahungu Dieudonné
Published: November 2024

Depuis 2019, Gitega remplace Bujumbura comme capitale politique du Burundi. Dans ce contexte, l’article interroge les modalités de la transformation des espaces urbains de Gitega et des pratiques et discours collectifs qui y sont associés. Notre hypothèse centrale est que, pour fabriquer la nouvelle capitale, l’État burundais cherche à la distinguer des autres villes en la dotant d’infrastructures et de cadres de vie modernisés, tout en réaffirmant ses fonctions cérémoniales (processus d’« emblématisation »). Notre étude, qui s’appuie sur l’analyse d’entretiens semi-directifs avec des habitants de Gitega (natifs ou fonctionnaires délocalisés), de sources institutionnelles et d’images satellitaires, montre que la ville acquiert progressivement les attributs qui sont pensés par le gouvernement comme ceux relevant d’une capitale (constructions en hauteur, grands équipements, etc.). Toutefois, ces transformations s’accompagnent aussi de tensions sociales : dirigisme des processus d’aménagement urbain, scepticisme et opposition d’une partie de la population, relégation des ménages les plus pauvres en périphérie de la ville. En fait, la fabrique de la nouvelle capitale répond surtout à un processus de renforcement de l’État qui souhaite démontrer sa capacité à conduire de grands projets et mettre en scène une sorte de renouveau quelques années après la crise institutionnelle de 2015.
Billet de réflexion : Brasilia, « la ville qui n’aurait pas dû exister », vient de fêter ses 64 ans
Authors: Oliveira Márcio de
Published: November 2024

Brasilia, « la ville qui n’aurait jamais dû exister », vient de fêter ses 64 ans. À l’heure actuelle, est-il possible de dire que l’aura et l’espoir soulevés au milieu du XXe siècle par le projet développementaliste et conquérant de l’ex-président Juscelino Kubitschek (1902-1976), confié au génie architectural d’Oscar Niemeyer et placé sous l’égide de l’urbaniste Lúcio Costa, restent de rigueur ? Revisitant les nombreux écrits sur ce projet-phare du modernisme brésilien, ce billet entend mettre en évidence les changements opérés dans la ville, qui sont autant d’écarts à l’idéal poursuivi par le projet développementaliste et ses expressions architecturales. Si l’affirmation de Brasilia comme capitale du Brésil a été progressive notamment en raison de l’urgence de sa construction et de la lenteur du processus de rééquilibrage politique et économique qui figurait au cœur du projet initial, elle a connu une série de réinventions qui en expliquent la place centrale qu’elle occupe aujourd’hui dans la scène urbaine, politique et culturelle du pays. Le billet revient sur quelques travaux consacrés à l’évolution de la ville depuis son inauguration, concluant sur le dynamisme de la scène culturelle, domaine qui constitue l’un des principaux atouts de l’actuelle capitale.
Aménagements en terrasses et dynamiques des systèmes ruraux dans les montagnes d’Afrique
Authors: Blond Ninon , Bart François , Lesourd Michel
Published: November 2024

En Afrique, nombre de montagnes connaissent une dense mise en terrasses, témoin de contraintes édaphiques, hydriques, démographiques, techniques mais aussi culturelles et politiques à la culture dans les terroirs de pentes. Qu’elles traduisent la lutte contre l’érosion pour l’autonomie alimentaire, l’affirmation d’un pouvoir pendant ou après les colonisations, ou des visées développementalistes par grands projets, les terrasses sont des objets situés historiquement, politiquement et géographiquement. L’approche par leur seule dimension technique ou traditionnelle se montre insuffisante et nécessite de réfléchir à leur articulation aux systèmes ruraux dans lesquels elles s’insèrent. Notre article tente une synthèse à partir de la bibliographie et d’expériences de terrain variées visant à faire ressortir la particularité de la situation africaine et la complexité d’un objet qu’on désigne sous le simple vocable « terrasse ».
Le bassin d’approvisionnement en bois-énergie de Bakel (Sénégal) : dépasser la seule distance pour penser la complexité géographique
Authors: Cisse Idrissa , Fourault Cauet Véronique
Published: November 2024

L’objectif de l’article est d’analyser la structure spatiale du bassin d’approvisionnement en combustibles ligneux dans la région de Bakel (Sénégal), en interrogeant le rôle de la distance à la ville de Bakel, principal centre de consommation de bois-énergie, dans un contexte rural et frontalier. L’hypothèse examinée est celle d’un bassin dont la compréhension ne peut se réduire à la distance spatiale au lieu de consommation. Dans un second temps, il s’agira d’analyser les facteurs mis en avant par les acteurs de la filière, qui font état de difficultés d’approvisionnement, ainsi que les stratégies d’adaptation qui en découlent. Notre hypothèse est celle d’un décalage entre les discours véhiculés par l’ensemble des parties prenantes de la filière, tant sur les causes et l’importance de la raréfaction de la ressource, et les stratégies, spatiales ou non, qui en découlent. Parmi elles, l’allongement simple de la distance spatiale entre marché de consommation et zone de collecte apparaît insuffisant, compte tenu de la complexité de l’organisation et des jeux d’acteurs observables dans le bassin.
Habiter en écovillage, une [éco]utopie du xxie siècle ?
Authors: Amar Sylvia
Published: November 2024

Nombreuses sont les initiatives qui se mobilisent aujourd’hui pour mieux habiter la Terre. Se positionnant comme des alternatives au monde urbain, les communautés intentionnelles et/ou écovillages font désormais partie des plus dynamiques et plus structurées. Depuis la fin des années 1990, les projets se multiplient à travers le monde, continuant de faire évoluer un mouvement ancien en un réseau international foisonnant et actif sur plusieurs fronts. Face à l’amplification des discours sur les enjeux écologiques, leurs actions concrètes sont particulièrement pertinentes à observer, notamment dans le contexte postérieur à la crise sanitaire mondiale de la Covid-19. Pour présenter la dimension holistique de leur démarche, l’article s’appuie sur les constructions sociospatiales mises en œuvre par quatre écovillages actuellement en activité : La Cité écologique (Canada/États-Unis), Torri Superiore (Italie), Hallingelille (Danemark), le Hameau des Buis (France). Si chacune de ces expériences est unique, toutes se rejoignent en plusieurs points : une volonté d’inscrire leurs choix de vie dans une démarche écologique et éducative connectée à leur territoire d’implantation, un socle de valeurs partagées de par le monde grâce aux outils numériques, un désir d’associer le fondement de leur projet social à la construction d’une architecture à même de l’incarner et d’en soutenir la dimension perfectible. Enfin, parce qu’elle s’inscrit dans une histoire des utopies architecturales qui croise celle des luttes environnementales, leur quête permet de mettre en perspective les enjeux d’éco-habiter contemporains. Vivre, Expérimenter, Construire, sont les axes proposés pour présenter les études de cas citées et mettre en évidence leur capacité à agir sur le réel, même à de très petites échelles.

Published: November 2024

Dès l’école maternelle, les élevages sont recommandés et particulièrement appropriés à la construction d’une démarche d’observation et à une première responsabilisation à l’égard de l’animal. La relation entre humains et non-humains constitue une thématique de recherche renouvelée au regard d’enjeux contemporains liés à la place des humains dans le vivant et à la protection de la biodiversité. Cette question est à l’interface des apprentissages scolaires scientifiques, de la prise en compte de la dimension affective dans ces apprentissages, et de l’acquisition d’une responsabilité vis-à-vis du vivant. Nous présentons les résultats d'une recherche collaborative menée dans quatre classes de maternelle multi-âges sur la construction d'une relation à l'animal. Les données relèvent d’entretiens avec des élèves afin de recueillir leur perception par rapport aux animaux élevés dans la classe (interview ante et post séquence) et d’une discussion autour des soins aux animaux. L'analyse des données permet d’identifier la nature des relations avec les animaux à travers l’implication de dimensions affectives, cognitives et morales dans leur perception de l’animal. Nous discutons de l’intérêt de développer une empathie interspécifique et de sa contribution à la construction d’une posture éthique vis-à-vis des animaux non humains.
Apprendre à enseigner en « classe intégrée » au sein d’un établissement scolaire régulier : des stagiaires genevois décrivent et commentent leur activité
Authors: Delorme Coralie
Published: November 2024

Cet article vise à décrire comment les étudiants en formation initiale d’enseignants spécialisés perçoivent la complexité du soutien aux apprentissages d’élèves à besoins éducatifs particuliers scolarisés dans une classe spécialisée intégrée au sein d’un établissement scolaire régulier et comment ils y font face lorsqu’ils apprennent à enseigner. Une étude qualitative menée à Genève (Suisse) auprès de trois étudiantes a permis d’analyser leur activité lors d’une séance d’enseignement menée en stage. Les données ont été obtenues grâce à des captations vidéo des stagiaires en train d’enseigner, ainsi qu’à la confrontation des stagiaires à ce film de leur activité dans le cadre d’entretiens d’autoconfrontation filmés. Les résultats révèlent les difficultés spécifiques aux étudiants-stagiaires lorsqu’ils apprennent à enseigner en classe intégrée. Ils soulignent l’intérêt de produire des connaissances susceptibles d’être remobilisées pour et dans la formation initiale des enseignants spécialisés.

The Manager From Leader to Institutional Entrepreneur, Influencer, or Sustainability Activist
Authors: Rodríguez Margarita Ruiz
Published: November 2024

This chapter aims to address the role of institutional entrepreneurs of sustainability exercised by the manager in the organization, and in society, from within it. To this end, the theoretical concepts of Organizational Institutionalism are applied. The institutionalization of sustainability in organizations, understood as the acceptance, inclusion and cultural and operational dissemination of these values, alters the role of managers. Its influence may transcend the organization, which may imply that the manager adopts an active role in championing, promoting and facilitating changes that may break with the dominant institutional logic in society. This may even be reflected in the professional and personal commitments assumed, in the acceptances, values, culture and behaviors shared and disseminated. Several current examples are presented by managers who could play this active role as influencers, or even as social activists for sustainability.
Beyond Leader-Centricity Embracing Followership in Global Leadership Dynamics
Authors: Sposato Martin
Published: November 2024

This chapter examines leader-centric approaches in leadership theories, advocating for a more inclusive understanding that considers followers' active role. It questions “global leadership” and explores cultural and contextual complexities challenging a one-size-fits-all approach. Followership theory is introduced as a vital perspective, emphasizing the dynamic interplay between leaders and followers in diverse global contexts. Practical examples illustrate how followership theory enhances leadership understanding in areas like organizational change, crisis management, technology implementation, cross-cultural leadership, and ethics. Integration of followership theory into leadership education and development is proposed. Emerging trends and future research directions are highlighted, including AI's role and the importance of adaptability.
Unlocking Organizational Potential
Authors: Belghait Fedwa , Imekhelaf Rachida
Published: November 2024

This chapter delves into the transformative potential of Neuro-Linguistic Programming (NLP) and Transactional Analysis (TA) in enhancing organizational dynamics and fostering individual and collective effectiveness in the workplace. NLP, based on modeling exceptional communicators and therapists, offers techniques such as dissociation, reframing, anchoring, and synchronization to reprogram the brain for better communication and personal growth. Similarly, TA, formulated by Eric Berne, examines human interactions through ego states—Parent, Adult, and Child—providing insights into communication dynamics and behavioral motivations. Integrating NLP and TA into leadership practices and organizational culture can unlock the full potential of employees, leading to improved communication, collaboration, conflict resolution, and decision-making. By leveraging these methodologies, companies can better navigate the complexities of human interaction, cultivating environments where individuals thrive, and organizations flourish in today's dynamic business landscape.

Published: November 2024

Organizations are becoming more and more conscious of the role that people play in achieving and preserving competitive advantage. According to the happy worker-productive worker thesis, employees who report feeling well-being at work will also perform well, and vice versa. However, organizations must know how to maintain such happy and productive employees. More recently, the movement for positive mental health has expanded beyond clinical settings and established a significant presence in workplace environments. Professors constantly attempt to balance their personal and professional obligations while dealing with the ubiquitous stress of handling expectations in a frequently hypercompetitive atmosphere. There is a constant worry that we might mess up, and if that were to happen, we would feel alone and responsible. The system makes the assumption that we are mature, skilled, and resilient enough to handle all the pressure that comes with the work.

Objetivo: compreender os sentidos atribuídos por cuidadores familiares de crianças e adolescentes com câncer ao tratamento quimioterápico. Método: estudo qualitativo, com análise secundária suplementar e ampliada de dois estudos desenvolvidos em enfermarias e ambulatório pediátricos, localizados no estado de São Paulo, Brasil.  A coleta de dados foi conduzida nos anos de 2017 e 2018, respectivamente. Os dados foram coletados por meio de entrevistas semiestruturadas com 37 cuidadores familiares e analisados conforme análise de conteúdo indutiva. Resultados: a amostra foi composta majoritariamente por mães. A quimioterapia foi percebida como um paradoxo entre o bem e o mal, descrita como um “veneno bom”, que desencadeia uma gama de sentimentos. Os participantes atribuíram a este tratamento os sentidos de um cotidiano repleto de desafios, caracterizados pelas dificuldades em lidar com os efeitos da terapia.  Considerações finais:  A quimioterapia é percebida pelos cuidadores familiares como um paradoxal "santo veneno", como um tratamento que, apesar de debilitar temporariamente a criança, é essencial para o manejo da doença. Este estudo enriquece o corpo da literatura científica, pois amplia a discussão sobre o tema. Adicionalmente, os resultados obtidos oferecem informações valiosas para os profissionais de saúde e permitem melhor compreensão da perspectiva das famílias durante o complexo processo de quimioterapia pediátrica.

Objetivo: descrever as táticas e estratégias, durante a pandemia de COVID-19, presentes nas práticas cotidianas dos profissionais de enfermagem e das instituições de saúde. Método: estudo de abordagem qualitativa realizado com 14 profissionais de enfermagem que atuaram no enfrentamento da pandemia de COVID-19. A coleta de dados ocorreu em agosto e setembro de 2021, por meio de entrevistas semiestruturadas, de forma remota. Os dados foram analisados a partir do referencial teórico do estudo do cotidiano norteado pelos conceitos de estratégia e tática de Michel Certeau. Resultados: os profissionais buscaram estratégias da ciência na sua vida privada, como realizar hábitos saudáveis. Estratégias do saber religioso também estiveram presentes. As táticas foram: o cuidado de flores; caminhadas na rua; assistir séries ou filmes. As instituições de saúde utilizaram como estratégia: organização das equipes; trabalho híbrido; oferta de apoio psicológico.  No trabalho, as táticas foram o compartilhamento de medos uns com os outros. Considerações Finais: conhecer o cotidiano dos profissionais de enfermagem, nesse momento pandêmico, contribui para compreender o impacto dessa experiência em suas vidas. A construção de saberes a partir das suas práticas cotidianas durante a pandemia de COVID-19 pode ofertar alternativas para enfrentamento dos desafios destes profissionais.

Published: November 2024

Background: Understanding population-specific food consumption patterns is useful for controlling diet-related health complications.
Objectives: This cross-sectional study aimed to identify the meal composition and timing of the meals among the public in Sri Lanka.
Materials & Methods: A nationally representative sample of adults was selected using a multi-stage random cluster sampling technique. Meal pattern data was derived from 24-hour dietary recalls.
Results: Almost all the surveyed respondents consumed three major meals, breakfast (97.6%), lunch (97.9%), and dinner (99.0%). Only 31.8% and 36.2% of the population had mid-morning and evening snacks, respectively. Vegetables were not consumed by 73.2%, 44.1%, and 58.2% of participants for breakfast, lunch, and dinner, respectively. Rice was the most common breakfast food item (67.7%), of which, 10% of participants consumed rice only with ‘coconut sambol'. Only 8.9%, 30.4%, and 11.8% of participants incorporated green leafy vegetables in their breakfast, lunch, and dinner in that order. Meat or meat equivalents were consumed by 28.8%, 60.8%, and 52.4% of participants for breakfast, lunch, and dinner, respectively. The most common snacks were biscuits/confectionaries and bakery foods. The time range between wake-up and breakfast was 00:30-07:00 hh: mm (Mean: 03:03 ± 1:17) while it was 00.15-05:45 hh: mm (Mean: 1:50 ± 0.56) between dinner and sleep onset.
Conclusions: The majority of the study population's meals are not deemed healthy and lack of variation in all dietary groups, including fruits, vegetables, dairy, meat or meat equivalents, and pulses. Biscuits, confectionaries, pastries, and other starchy foods were the most common snacks. There was a significant variation in meal timing among these groups.

Since the role of the liver in metabolic dysfunction, including type 2 diabetes mellitus, was demonstrated, studies on non-alcoholic fatty liver disease (NAFLD) and metabolic dysfunction-associated fatty liver disease (MAFLD) have shown associations between fatty liver disease and other metabolic diseases. Unlike the exclusionary diagnostic criteria of NAFLD, MAFLD diagnosis is based on the presence of metabolic dysregulation in fatty liver disease. Renaming NAFLD as MAFLD also introduced simpler diagnostic criteria. In 2023, a new nomenclature, steatotic liver disease (SLD), was proposed. Similar to MAFLD, SLD diagnosis is based on the presence of hepatic steatosis with at least one cardiometabolic dysfunction. SLD is categorized into metabolic dysfunction-associated steatotic liver disease (MASLD), metabolic dysfunction and alcohol-related/-associated liver disease, alcoholrelated liver disease, specific etiology SLD, and cryptogenic SLD. The term MASLD has been adopted by a number of leading national and international societies due to its concise diagnostic criteria, exclusion of other concomitant liver diseases, and lack of stigmatizing terms. This article reviews the diagnostic criteria, clinical relevance, and differences among NAFLD, MAFLD, and MASLD from a diabetologist’s perspective and provides a rationale for adopting SLD/MASLD in the Fatty Liver Research Group of the Korean Diabetes Association.
Ultra-Processed Foods and the Impact on Cardiometabolic Health: The Role of Diet Quality
Authors: Wang Xiaowen , Sun Qi
Published: November 2024

The consumption of ultra-processed foods (UPFs) has surged globally, raising significant public health concerns due to their associations with a range of adverse health outcomes. This review aims to elucidate potential health impacts of UPF intake and underscore the importance of considering diet quality when interpreting study findings. UPF group, as classified by the Nova system based on the extent of industrial processing, contains numerous individual food items with a wide spectrum of nutrient profiles, as well as differential quality as reflected by their potential health effects. The quality of a given food may well misalign with the processing levels so that a UPF food can be nutritious and healthful whereas a non-UPF food can be of low quality and excess intake of which may lead to adverse health consequences. The current review argues that it is critical to focus on the nutritional content and quality of foods and their role within the overall dietary pattern rather than only the level of processing. Further research should dissect health effects of diet quality and food processing, investigate the health impacts of ingredients that render the UPF categorization, understand roles of metabolomics and the gut microbiome in mediating and modulating the health effects of food processing, and consider environmental sustainability in UPF studies. Emphasizing nutrient-dense healthful foods and dietary patterns shall remain the pivotal strategy for promoting overall health and preventing chronic diseases.
