В технологии подготовки химического сырья или топлива из попутного нефтяного газа предусмотрено сжигание попутного газа в факелах низкого давления, при этом в атмосферу выбрасываются сажа (C), диоксид азота (N), оксид углерода (CO2) и метан (CH4). Для оценки состояния атмосферы в районе нефтегазодобычи предложен комплексный подход к моделированию полей рассеивания загрязняющих веществ в приземном слое воздуха от факельных установок на территории Мамонтовского месторождения Нефтеюганского района ХМАО. Этот подход включает моделирование концентраций С, NO2, CO2 и CH4 с использованием программы «УПРЗА Эко-Центр» и наземных (определение содержания органических соединений в почвах) и спутниковых данных (AIRS) о концентрации парниковых газов. Данный подход позволяет проводить комплексные мониторинговые исследования состояния окружающей природной среды удаленных северных нефтегазодобывающих территорий на основе спутниковых и наземных данных.

A comprehensive approach to simulation of the fields of dispersion of pollutants in the surface air layer from flare installations on the territory of the Mamontovskoye field of the Nefteyugansk district of the KhMAO is suggested. It includes the simulation of pollutant concentrations (carbon monoxide, nitrogen dioxide, and soot) with the use of UPRZA Eco-Center software based on terrestrial data on the content of organic compounds in soils and satellite data (AIRS) on greenhouse gas concentrations. This approach enables comprehensive studies of the state of the natural environment in remote northern oil and gas producing areas on the basis of satellite and ground-based data.
УПРАВЛЕНИЕ СПЕКТРАЛЬНЫМ СОСТАВОМ КОГЕРЕНТНОГО ИЗЛУЧЕНИЯ НА ИОНАХ МОЛЕКУЛЯРНОГО АЗОТА В ЛАЗЕРНОЙ ПЛАЗМЕ ПРИ ДВУХЦВЕТНОЙ НАКАЧКЕ

Published: February 2025

В последние годы бурно развиваются лазерные источники, создаваемые в воздушной лазерной плазме мощными фемтосекундными импульсами излучения. В настоящей работе представлены результаты исследования генерации когерентного излучения на ионах молекулярного азота в лазерной плазме при использовании двухцветной накачки на длинах волн 950 и 475 нм. Показано, что добавление излучения второй гармоники, длина волны которой расположена ближе к линиям генерации на N2+ по сравнению с первой гармоникой, повышает интенсивность и стабильность излучения суперконтинуума, выступающего в качестве затравочного излучения для генерации. Такая накачка позволяет получать генерацию на новых линиях и управлять интенсивностью и спектральным составом генерации. Результаты исследования могут быть полезны для установления механизма(-ов) создания инверсии населенности в лазерной плазме на ионах молекулярного азота.

In recent years, laser sources created in airborne laser plasma by powerful femtosecond radiation pulses have been rapidly developing. This work studies coherent radiation generation on N2+ ions in laser plasma using two-color pumping at l = 950 and 475 nm. It is shown that the addition of second harmonic radiation, wavelength of which is closer to the lasing lines on ions compared to the first harmonic, increases the intensity and stability of supercontinuum radiation which acts as seed radiation for the lasing. Such pumping allows lasing on new lines and controlling the intensity and spectral composition of the generated radiation. The results can be useful for establishing the way(s) of creating population inversion in laser plasma on molecular nitrogen ions.

Basil essential oil: Estragole content and chemical profiles
Authors: Arsenijević J. , Jovanović A. , Kovačević N. , Drobac M.
Published: February 2025

Basil (sweet basil, Ocimum basilicum L.) is an aromatic plant known for its culinary and traditional medicinal uses.

The content of estragole (methyl chavicol), a compound associated with a potential risk to human health, was determined in the essential oils of 12 samples of basil herb by gas chromatography with flame ionisation and mass spectrometry detection (GC-FID/MS) using an external standard method. The essential oils contained estragole at various levels, from 1.85 to 561.01 mg mL−1. Regarding the chemical profile, among the eleven essential oils, the compound with the highest relative proportion was linalool (29.1–70.3%), while estragole dominated in one essential oil with a relative proportion of 45.2%. All essential oils tested correspond to the European chemotype, which is characterised by a high content of linalool or a combination of linalool and estragole.

Given the recommendation for limiting human exposure to estragole, the safety of some essential oils may be of concern due to their high levels of estragole content.

The results indicate the importance of the chemical analysis of basil herb samples and the selection of chemotypes with low estragole content.
Three generations of infinite-layer nickelate crystals
Authors: Suyolcu Y. Eren , Puphal Pascal , Hepting Matthias
Published: February 2025

Topotactic transformations between related crystal structures represent a powerful method for synthesizing novel quantum materials. In particular, the groundbreaking discovery of superconductivity in nickelates with the infinite-layer (IL) crystal structure—achieved through the topotactic oxygen reduction of the perovskite phase—has sparked recent interest in topotactic methods. However, while most topotactic reductions of nickelates were performed on polycrystalline powders or thin films, single-crystalline samples, which are the gold standard for physical property measurements in quantum materials, remain underexplored. Here, we summarize our progress in synthesizing IL nickelate bulk crystals. We review both breakthroughs and limitations encountered, and also discuss critical insights into the microstructural effects of the topotactic transformation of bulk crystals provided by scanning transmission electron microscopy.

Published: February 2025

The massive influx of Sargassum spp. to the Mexican Caribbean coasts poses significant environmental, economic, and health challenges. This study explores the potential use of Sargassum spp. as a biosorbent material for contaminant removal. Some of the pollutants found in water bodies in some coastal areas are those derived from soaps and detergents, such as sulfates and phosphates. Therefore, the biosorbent capacity of Sargassum spp. to remove this type of substance dissolved in water was studied. The removal efficiency, for both pollutants, was greater than 90% when a concentration of 900 mg*L−1 was used. The capacity of Sargassum spp. to be used in several cycles was demonstrated, maintaining its biosorbent capacity. The structural changes in Sargassum spp. after biosorption were characterized by scanning electron microscopy, demonstrating the presence of sulfates and phosphates on Sargassum spp. Therefore, this work proposes an efficient, economic, and sustainable removal system based on Sargassum spp.

Published: February 2025

OBJECTIVES Mental fatigue has been shown to negatively impact physical performance, including motor skills and neuromuscular function. This study aimed to investigate the effects of mental fatigue on gait performance and variability in healthy young male adults.METHODS Eighteen participants walked over-ground at their preferred speed before and after completing a mentally fatiguing Stroop task. Kinematic data were recorded to assess gait variables such as speed, step length, step time, and step width, along with their coefficients of variation (CV). Subjective ratings of mental fatigue were also collected.RESULTS While subjective ratings of mental fatigue significantly increased following the Stroop task, no significant changes were observed in gait performance or CV variables at the group level. However, singlesubject analyses revealed that some participants experienced significant increases or decreases in gait speed, suggesting gait performance responses to mental fatigue are individual-specific.CONCLUSIONS These findings indicate that although mental fatigue increases perceptibly, it may not uniformly affect gait performance in simple walking tasks. Factors such as the duration and intensity of the fatigue-inducing task, individual coping strategies, and the nature of the gait task, particularly the participant's preferred speed, likely influenced these results. Future research should explore more complex gait tasks and varied mental fatigue protocols to better understand this relationship.

Authors: Ahn Won-Chul , Min Kyoung-Bin , Kim Myung-Ki
Published: February 2025

OBJECTIVES This study aims to compare core muscle activation at varying hip flexion angles during core exercises based on Dynamic Neuromuscular Stabilization (DNS).METHODS Nine healthy male participants, without musculoskeletal or hypertension disorders, performed core exercises at hip flexion angles of 45°, 90°, and 130°, while their muscle activation levels were measured using electromyography (EMG).RESULTS While differences in muscle activation were observed across all muscles depending on the hip flexion angle, significant results were found specifically in the rectus femoris, rectus abdominis, and external oblique muscles at different angles (p < 0.05).CONCLUSIONS These findings suggest that varying hip angles can selectively engage different core muscles, which may inform rehabilitation and strength training programs targeting specific areas of the core. Further research with a larger sample size and diverse populations is recommended to generalize these findings.

Published: February 2025

OBJECTIVES This study aimed to compare training and practice volumes (extrinsic factors) and physical characteristics (intrinsic factors) between elite youth baseball players with and without LBP.METHODS A total of 271 elite youth baseball players (aged 8–16 years) were divided into two groups based on the presence or absence of a lifetime history of LBP. Data on training and practice volume, flexibility, and demographic characteristics were collected through questionnaires and physical assessments. Statistical analyses, including independent t-tests and Pearson’s chi-square tests, were conducted to determine differences between groups.RESULTS Players in the LBP group exhibited significantly greater training and practice volumes compared to their non-LBP counterparts. Reduced flexibility was observed in the LBP group, particularly in the quadriceps femoris on both dominant and non-dominant sides (p<.001) and in the biceps femoris (hamstring) on the non-dominant side (p<.034). A higher prevalence of shoulder (28.5% vs. 16.8%) and elbow pain (44.3% vs. 27.4%) was noted in the LBP group compared to the non-LBP group.CONCLUSIONS This study found that low back pain in youth baseball players was associated with reduced lower extremity muscle flexibility and that players with back pain were more likely to develop shoulder and elbow injuries. Future prospective studies are necessary to establish a clearer causal relationship between low back pain and upper extremity injuries, particularly in the shoulder and elbow.

Authors: Iskajyan Armine H.
Published: February 2025

In today’s digital age, social media has become an integral part of daily life for millions, especially adolescents. Online platforms provide opportunities for connection and self-expression. However, this digital landscape also poses significant threats, including cyberbullying and dangerous online challenges that can lead to self-harming behavior and other negative consequences. The objective of this study is to investigate the psychological impact of dangerous online challenges on adolescents. A particular focus is placed on how social media influences adolescent behavior and their quest for peer validation. We employed a case study method to gain an in-depth understanding of the motivations and experiences of adolescents participating in dangerous online challenges. The results show that the desire to gain peer approval often leads adolescents to take risks without considering the possible consequences: serious physical injury, psychological stress, anxiety, depression. Low self-esteem and family conflicts exacerbate the situation. This is study highlights the urgent need to improve digital literacy and mental health awareness among adolescents. Creating a supportive environment is key to protecting young people from the dangers of online challenges, building healthy coping strategies and resilience to the negative impact of social media.

Authors: Morgado Sergio Mascarenhas , da Fonseca Erica Lourenço , Vicente Ana Carolina Paulo
Published: February 2025

BACKGROUND Non-O1 and non-O139 Vibrio cholerae (NOVC) that cause bacteraemia have attracted the attention of the public health community around the world, mainly due to the prospect of outbreaks and the way to treat such infections. OBJECTIVES To identify V. cholerae lineages and their antibiotic resistance and virulence factors associated with bacteraemia. METHODS Vibrio cholerae genomes associated with strains isolated from blood were retrieved and subjected to core genome-based phylogenomic analysis with Roary. The virulome and resistome were searched with abricate using the VFDB and CARD databases. FINDINGS Analysis showed that, in addition to V. cholerae, Vibrio paracholerae also causes bacteraemia. The NOVC group was highly diverse, although genomes from different countries were related. Most bacteraemic Vibrios came from countries not affected by epidemic/endemic cholera. The NOVCs virulome presented factors, such as type III and VI secretion systems, HapA, HlyA, RTX, and TLH. Importantly, no resistance to third-generation cephalosporin has been identified in the resistome of NOVCs. MAIN CONCLUSIONS The presence of multiple NOVC lineages that cause bacteraemia in different parts of the world shows that there is no geographic and socioeconomic restriction for these cases. Therefore, healthcare systems need to be aware of this uncommon but deadly Vibrio infection.

Published: February 2025

Haemosporida research started in the 19th century with the description of Plasmodium and other related parasites infecting mammals and birds. Here, we highlight the pioneering contributions of Henrique Aragão and Arthur Neiva in describing the first two Plasmodium species in lizards from the New World, Plasmodium diploglossi and Plasmodium tropiduri, published in the first printed issue of Memórias do Instituto Oswaldo Cruz in April 1909. We use these discoveries as a background to explore some historical and taxonomic aspects of Plasmodium species infecting reptiles, with a particular emphasis on the advancements made over the past 115 years in the Neotropics. Our review underscores the complexities and persistent challenges in the taxonomic classification of reptile haemosporidians and discusses some scientific advances in the field that improved our understanding of the biology and evolution of these parasites.

Published: February 2025

Abstract Understanding the nature of musculoskeletal tumors is crucial for appropriate management and to secure a favorable prognosis. Orthopedists’ ability to identify these pathologies early and accurately is paramount. There is a requirement to raise awareness within the orthopedic community regarding the necessity of referrals to orthopedic oncology specialists, as delays in initiating proper treatment can compromise patient prognosis. Objective: The objective was to assess the capability of non-specialist orthopedists in identifying bone lesions suggestive of tumors and thus classify them by employing a questionnaire with radiographs and comparison with specialists. We aim to gain an in-depth understanding of their diagnostic competence and provide insights into teaching the subject in orthopedic residency programs. Methods: The sample consisted of 90 participants who answered the questionnaire: 18 orthopedic oncology specialists, 58 non-specialist orthopedists, and 14 orthopedic residents. Results: Specialists achieved an average accuracy of 12.50 ± 1.07, while non-specialists scored 10.00 ± 0.60 (p<0.001). Among non-specialists, there was no statistical significance when comparing whether they underwent specialization internship during residency nor the duration of the year of such training. The period since graduation also indicated no differences. Conclusion: This study highlights the importance of referring patients with suspected tumors to specialized orthopedists.

Published: February 2025

Abstract This study aimed to compare fixed-bearing and mobile-bearing knee unicompartmental arthroplasty implants in adults (in the medial compartment) to determine which is better for each patient and their particularities. The research focused on postoperative assessments with a follow-up of at least a 2-year, examining both quality of life and mid-term functionality in the medium term. A systematic keyword search was executed in the PubMed, EMBASE, and Cochrane databases, employing a filter for randomized clinical trials and without language limitations. The search yielded 113 articles from March 28, 2024, including 83 from PubMed, 12 from EMBASE, and 18 from the Cochrane Library. The study found insufficient evidence to establish the superiority of one prosthetic type over the other regarding post-operative function, pain, complications, revisions, and quality of life after a 2-year follow-up. Literature highlights uncertainties in comparing UKA types due to varied assessment tools. No conclusive evidence favors either type regarding post-op function, pain, complication rates, revisions, or quality of life after 2 years. Urgent need for standardized, long-term, multicenter studies to inform evidence-based clinical practice. Level of Evidence I; Systematic review of randomized controlled trials.

Abstract In the production of kale, nitrogen is one of the nutrients that the plant needs in greater quantity. Its application must be divided throughout the cycle, due to the loss by leaching. The objective of the research was to evaluate the effect of splitting organic fertilizers in topdressing on the production of kale. The experimental design was randomized blocks, with four replications, with seven treatments being evaluated in a 2 x 3 + 1 factorial scheme, the first factor was the fertilizers (castor bean cake and bokashi) and the second the application intervals (7; 14 and 21 days), in addition to the control without topdressing fertilization. The amount of each fertilizer was calculated to provide the same dose of N (40 kg ha-1) every 21 days. The following characteristics were evaluated: plant height (PH), stem diameter (SD), number of leaves per plant (NLP), leaf fresh matter mass (LFMM), leaf length at the beginning (LLB), middle (LLMe) and end (LLE) of the cycle and “SPAD” index. There was no interaction between the factors, for any characteristic evaluated. For all traits, the values observed in control was lower than treatments with topdressing. The increases of treatments of factorial in relation to the control were 37.8% (plant height); 31.8% (SD); 157.1% (NLP); 213.5% (MLFMM); 7.6% (LLB); 80.2% (LLMe) and 126.6% for the “SPAD” index. It is recommended to use castor bean cake and split it every 21 days as it results in less labor for application.

ABSTRACT The rootstock Poncirus trifoliata var. monstrosa flying dragon (FD) induces dwarfism to citrus trees. Dwarfism provides several positive aspects: allows dense planting, reduces the pruning frequency, improves productivity efficiency, and makes cultural practices easier. Evaluating the compatibility of the rootstock with different scion varieties is crucial for recommending this rootstock and requires many years of field observations. The aim of this investigation was to evaluate the vigor and graft compatibility of Citrus × sinensis L. Osbeck and Citrus × latifolia Tanaka grafted onto FD. The experimental was a randomized block design, with five treatments, four replications, and each plot consisting of one tree. The cultivar Tahiti acid lime IAC-5 and Seleta, Lima, Bahia, and Folha Murcha oranges were the evaluated plants. Biometric measurements of canopy and graft incompatibility were assessed, and viables spacing were estimated. No signs of incompatibility were observed in any graft combination. After 12.5 years, FD induced dwarfism in all evaluated cultivars, but not to Tahiti acid lime. In the edaphoclimatic conditions of North Fluminense, we suggest planting densities of 511, 1,387, 1,486, 792 and 1,644 plants.ha-1 to Tahiti, Seleta, Lima, Bahia, and Folha Murcha oranges trees, respectively, when these are grafted onto the FD.

Resumo Diversos estudos argumentam que a pandemia de COVID-19 poderia ser um catalisador para a construção de sistemas alimentares sustentáveis. Entre os atores envolvidos nesse debate, destaca-se a importância dos ministérios da agricultura na formação de agendas e políticas governamentais. Partindo dos debates sobre a definição de agendas, este artigo tem o objetivo de analisar como a pandemia de COVID-19 se manifestou na agenda simbólica e nas questões relacionadas aos sistemas alimentares priorizadas pelos ministérios da agricultura do Brasil, Chile e Colômbia, a partir dos conteúdos do Facebook publicados ao longo de 2020. Em termos metodológicos, propôs-se o mapeamento das postagens, seleção daquelas relacionadas à COVID-19, análise e classificação em categorias. Os resultados indicam que os ministérios dedicaram diferentes níveis de atenção à pandemia; no entanto, em todos os casos, a pandemia perdeu espaço na agenda simbólica no segundo semestre de 2020. Contrariando as expectativas de mudança transformadora, as postagens dos ministérios visavam manter as dinâmicas existentes nos sistemas alimentares.
CORPOS ALETÚRGICOS: A VONTADE DE MATAR COMO REGIME DE VERDADE DAS PRÁTICAS DE SEGURANÇA

Published: February 2025

Resumo Este artigo objetiva o enfrentamento da branquitude que, em uma sociedade organizada pelo racismo, produz lugares de privilégio nas relações de poder e, neste trabalho, foi tomada como o elemento que articula a violência incontornável e a vontade de matar, no âmbito das práticas de segurança. Metodologicamente, fazemos uso de cenas como ferramentas de mobilização das narrativas urbanas da/sobre a violência que nos permitem analisar os regimes de verdade que possibilitam empreender uma ontologia do presente e dos processos de subjetivação a partir do incomodamento: como se constitui e se mantém a eficácia da letalidade? As análises permitem argumentar que, no Brasil, opera-se uma violência incontornável, que se sustenta nas lógicas da branquitude, produzindo espaços de criminalidade e matabilidade. Nessa conjuntura, sustentamos que branquitude e seus privilégios fazem o vínculo entre a incontornabilidade da violência e a vontade de matar, as quais constituem corpos aletúrgicos, no âmbito das práticas de segurança.

Resumo Recorte de pesquisa que circunscreve o modo como as políticas universitárias de ações afirmativas impacta na subjetividade de estudantes negras. Analisa as narrativas de duas jovens universitárias na interface entre Psicanálise e Psicologia Social, valendo-se da metodologia das narrativas memorialísticas, técnica de entrevista que parte do convite disparador “conte-me sua vida” para compreender a interação do sujeito com os vários eventos da vida e seus efeitos na dimensão social e psíquica. A análise extraiu do discurso das participantes os meios pelos quais constroem posicionamentos que lhes permitem lidar com o racismo estrutural. Constatou-se que as relações de ancestralidade são potentes no enfrentamento ao racismo e na construção de uma autodefinição de si. As políticas afirmativas, ao oferecem acesso ao conhecimento acadêmico, legitimam o conhecimento originário, impactando positivamente no sofrimento psíquico produzido pelo mal-estar colonial.
PSICOLOGIA SOCIAL (CRÍTICA) DO TORCER: CAMINHOS TRILHADOS E CAMINHOS A SE TRILHAR
Authors: Lopes Felipe Tavares Paes
Published: February 2025

Resumo Neste artigo, revisito e discuto a pertinência de algumas teses sobre o(a) torcedor(a) de futebol oferecidas por autores vinculados à perspectiva crítica do esporte, a fim de abrir caminho para um enfoque mais construtivo para o desenvolvimento de uma psicologia social (crítica) do torcer. Ao realizar essa discussão, analiso como essa perspectiva tem abordado a “massa-torcedora”, o(a) próprio(a) torcedor(a), seu corpo e sua capacidade de organização política. Feito isso, defendo o emprego de uma abordagem multiperspectívica como instrumento de análise psicossocial das torcidas de futebol.

Abstract An association between bruxism and musculoskeletal disorders, such as neck pain, has been established. This study investigated the association of possible sleep bruxism (PSB) activities, including grinding, bracing, and thrusting, with smartphone use, smartphone-induced neck pain, and sleep features. This cross-sectional study involved 403 Brazilian adolescents aged 11 to 19 years. A self-administered questionnaire was used to assess the severity of PSB, smartphone use, smartphone-induced neck pain, and sleep features (sleep duration and quality and history of nightmares). Sociodemographic factors, as well as snoring and drooling on the pillow, were considered potential confounders and were assessed based on reports from parents/caregivers. Participants were selected using multiple-stage sampling. Descriptive analysis and multinomial regression were performed (p ≤ 0.05). Adolescents reporting nightmares at least once a month (OR = 3.402; 95%CI: 1.315–8.802) and sometimes experiencing smartphone-induced neck pain (OR: 3.697, 95%CI: 1.103–12.388) were more likely to report moderate/severe grinding. Drooling on the pillow (OR = 3.105, 95%CI: 1.316–7.329), poor/fairly good sleep quality (OR = 2.717, 95%CI: 1.279–5.770), and smartphone-induced neck pain (OR = 3.227, 95%CI: 1.121–9.285) were associated with mild bracing. Adolescents experiencing nightmares once a week (OR = 3.209, 95% CI: 1.202– 8.565) had a higher prevalence of mild thrusting. Self-reported smartphone-induced neck pain, nightmares, poor/fairly good sleep quality, and drooling on the pillow were associated with a higher prevalence of PSB activities among Brazilian adolescents. Clinicians and researchers are encouraged to include assessments of smartphone use and sleep features in anamnesis, promoting a comprehensive approach to PSB, from diagnosis to treatment.
Comparative discourse analysis of logical memory recall in normal elderly from rural and urban areas

Published: February 2025

ABSTRACT This study examined the nature of errors in prose recall made in normal aging from different cultural backgrounds: rural and urban areas. Objective: The aim of this study was to examine the nature of errors in prose recall made in normal aging from different cultural backgrounds. Methods: We evaluated neurologically normal elderly divided into two groups: 12 subjects resident in a rural area in Central Brazil (group 1, called “Interior”) and 10 subjects from a metropolitan area in a big city in Central Brazil (group 2, called “Metropolis”). Responses by 22 nondemented older adults to the Logical Memory subtest of the Wechsler Memory Scale were examined in a propositional analysis. Results: Healthy older adults from rural areas (interior group) showed good immediate recalls, but had deficits in retention over a delay. Subjects from urban areas made errors of omission, not commission, at immediate recall. Conclusion: These errors probably reflect difficulty with attentional control rather than memory per se. There are differences in the performance of the elderly when considering different levels of education for neuropsychological tests associated with immediate recalls (but not with delayed recall), suggesting that working memory systems may be more impacted by years of schooling than the coding memory system.
Machiavelli against Imperialism: a Critique of Roman Expansionism and a Call for a Confederative Solution
Authors: Silva Ricardo
Published: February 2025

Machiavelli’s republicanism is grounded on two primary aspirations: the preservation of freedom within republics and the expansion of their territories. However, these goals are not indefinitely compatible, as an imperialist foreign policy ultimately undermines a free way of life. An influential understanding of Machiavelli’s ‘republican dilemma’ suggests that he unequivocally prioritized imperial expansion over preserving freedom when these ends collided. This interpretation points to Machiavelli’s endorsement of the Roman model, which sacrificed its own freedom to expand its dominion over other peoples, as evidence of such a preference. This article challenges the notion of Machiavelli's imperialist intent, arguing that this interpretation not only overlooks Machiavelli’s critique of Roman imperialism but also ignores a non-imperialist alternative to territorial expansion presented in the ‘Discorsi’: the formation of leagues or confederations of free states for mutual defense. The league-based model of territorial expansion is the only approach that can effectively update Machiavelli’s international thought, aligning best with the contemporary republican ideal of freedom as non-domination.
Experience at the Mobile Emergency Care Service during internship: an experience report
Authors: Barbosa Guilherme Chacon Martinez Dastre , Siqueira Leonardo de Sousa
Published: February 2025

ABSTRACT Introduction: This study aims to report the experiences lived in the Mobile Emergency Care Service (SAMU) of the city of Santos, São Paulo, Brazil, by fifth-year medical students from Centro Universitário Lusíada during their internship. Experience Report: Part of the time, the students were stationed at the Regulation Center, in a space specifically reserved for Medical Regulation, dedicated to handling calls already directed and triaged to the emergency number 192. At other times, the students participated in theoretical-practical classes covering the main topics of pre-hospital care, and when possible and necessary, they would go out in an ambulance to provide assistance to victims within the municipality. Thus, the students had the opportunity to refine their actions in urgent and emergency situations with patients, particularly through a more succinct and objective approach. Discussion: The service environment was distinct from university hospitals or specialty outpatient clinics to which the students were more accustomed, as the current setting was much more dynamic. It provided the students with the opportunity to hone their communication and leadership skills, crisis management, as well as to revisit and refine essential topics for their profession, whether as a general practitioner or an emergency physician. All of this occurred in a supportive environment provided by the teachers and SAMU workers who supervised them, enhancing the students’ appreciation for these days. Conclusion: The weeks spent in the service were reported by the students as extremely valuable, allowing them to contemplate the challenges faced by the workers in the field on a daily basis. Moreover, it promoted the perception of the Mobile Emergency Care Service as a potential career path for these university students in the near future, in addition to aiding in the enhancement of medical knowledge and the training of soft skills for those involved.
National museums, decolonial heritage practices and persistent epistemic violence in the Philippines and Brazil: the (non-)place of sexual and gender diversity
Authors: Gontijo Fabiano
Published: February 2025

Abstract National museums are produced by national ideologies while simultaneously contributing to the reproduction of national narratives. They can be thought of as a biopolitical governmentality dispositive, thus representing tensions related to maintaining bodypolitics, biopolitics and geopolitics within and beyond national realms. They rarely address the sexual and gender diversity of their respective countries in their exhibitions. This paper aims to present the results of a reflection on the violence exerted by such museums in erasing sexual and gender diversity from their narratives and, consequently, reproducing a certain form of homolesbotransphobia. Building upon the contested nature of the idea of nationhood, decolonial interventions carried out in national museums will be discussed, which have been attempting to problematize these issues through the diversification of their exhibitions, as seen in the National Historical Museum in Brazil and the National Museum of Anthropology in the Philippines.

Resumo Este texto trata o Sistema Interamericano de Direitos Humanos como arena política de correlação de forças entre sociedade civil e Estados nacionais, incluindo-se o Brasil. A partir de pesquisa documental na base de dados da Corte Interamericana de Direitos Humanos, foram estabelecidos elementos para compreensão do efeito das regulações morais das sexualidades em contextos latino-americanos e caribenhos. Nessa região, os processos democráticos constantemente interrompidos por Golpes de Estado e a incipiência de uma justiça de transição consistente, delineiam os contornos de uma política sexual conservadora, cujos valores reforçam o modelo de família cisheterocentrado, a branquitude e o mandato de masculinidade como elementos coloniais determinantes. A compreensão dos movimentos sociais, em especial LGBTI+, leva a entender como se articulam as redes político-comunicativas, formais e informais, entrelaçando pessoas, práticas, ideias e discursos de combate às violências baseadas na orientação sexual, identidade de gênero e características sexuais. Diante disso, são oferecidos elementos para descrição, interpretação e análise da LGBTIfobia de Estado em suas tramas de desproteção social, violência arquivística e de negligência com crimes de ódio.
