CRUPE VIRAL EM PEDIATRIA: ETIOLOGIA, DIAGNÓSTICO, TRATAMENTO E PREVENÇÃO
Authors: Moreira Gabriela Irrthum , Santos Milena Pereira , Carneiro Luisa Machado , Assunção João Victor Xavier
Published: September 2024

O crupe viral, também conhecido como laringotraqueobronquite, é uma infecção respiratória aguda que afeta principalmente crianças menores de cinco anos, com maior incidência entre um e três anos de idade. É causada principalmente por vírus respiratórios, sendo o vírus parainfluenza o mais comum, seguido pelo vírus sincicial respiratório, adenovírus e rinovírus. A inflamação resultante atinge a laringe, traqueia e brônquios, levando à obstrução das vias aéreas superiores e desencadeando sintomas característicos como tosse rouca, estridor inspiratório e rouquidão. Em casos mais graves, pode ocorrer insuficiência respiratória, exigindo tratamento imediato. O diagnóstico é majoritariamente clínico, com base na apresentação dos sintomas, enquanto exames de imagem, como radiografia, são usados apenas em casos onde há dúvida diagnóstica. O tratamento depende da gravidade do caso, variando desde cuidados de suporte, como hidratação e nebulização com solução salina, até o uso de corticosteroides, como a dexametasona, que demonstrou eficácia na redução da inflamação e dos sintomas. Em situações de maior gravidade, a nebulização com epinefrina é utilizada para aliviar rapidamente o edema e melhorar a ventilação. A maioria dos casos evolui de forma benigna, com resolução espontânea em até 48 horas, mas é importante monitorar pacientes com maior risco de complicações, como aqueles com doenças respiratórias preexistentes. Medidas preventivas, como a vacinação contra influenza e cuidados higiênicos, são fundamentais para reduzir a disseminação dos vírus causadores, especialmente em ambientes frequentados por crianças. O manejo adequado e a prevenção podem reduzir significativamente a morbidade associada ao crupe viral, promovendo melhores desfechos para as crianças afetadas.
New data for a model update of the Waiwera geothermal reservoir in New Zealand
Authors: Kühn Michael , Stagpoole Vaughan , Viskovic Graham Paul D. , Kempka Thomas
Published: September 2024

Abstract. Waiwera is a small coastal village located on New Zealand's North Island above a geothermal reservoir. The origin of the hot water is not well understood. An inferred fault zone at the base of the reservoir is thought to channelise the uprising thermal water. The most recent geological model of Waiwera integrates the depositional environment, mineralogical composition and stratigraphic structures. Coupled numerical fluid flow, heat and transport simulations indicated that further model revisions are required, with support by additional field campaigns, to increase the knowledge of the complex reservoir geology. In this study, gravity data were acquired around the greater Waiwera area. Its interpretation shows a potential fault downthrow in the basement. This feature was tested using a revised geological model in view of a focus for the hot water to rise upwards. The observed characteristic cold and hot water distribution in the system was simulated and the temperature profiles show an improved agreement in the near field around the centre of the reservoir.
Technical note: A validated correction method to quantify organic and inorganic carbon in soils using Rock-Eval® thermal analysis

Abstract. Soils contain large amounts of carbon stored as organic carbon and carbonates. These carbon pools can contribute to climate regulation and are of primary importance in ensuring proper soil functioning. However, their accurate quantification remains a complex task. Rock-Eval® thermal analysis has emerged as an alternative to classic dry combustion and wet methods due to its ability to simultaneously provide organic and inorganic carbon measurements on the same subsample. However, it has been observed that Rock-Eval® systematically underestimates the soil organic carbon (SOC) while overestimating the soil inorganic carbon (SIC). In this technical note, we propose a validated correction of both SOC and SIC based on a machine-learning model and using a diverse dataset of 240 soil samples. We show that the proposed correction significantly increases the accuracy of the Rock-Eval® method when compared to reference SOC and SIC values and applied to the dataset used for training and testing and that it can be successfully applied to data originating from different Rock-Eval® machines without changing the routine analytical protocol. The transferability of the model allows for its future implementation in the Geoworks software so that Rock-Eval® machines can routinely provide accurate SIC and SOC measurements.

Published: September 2024

Este artigo tem o objetivo de analisar os efeitos do neoliberalismo escolar na educação brasileira, explorando suas operações nas políticas públicas e suas táticas de controle subjetivo. Os referenciais teóricos incluem autores como Laval (2019), Guattari (1992), Freitas (2014a), Leher (2022) e Motta (2013), fornecendo uma base crítica para investigar as relações entre neoliberalismo e educação. Utilizando uma abordagem pautada na Psicologia Social, foi realizada uma revisão bibliográfica, configurando cinco categorias explicativas referentes às diversas camadas desse fenômeno. Os resultados revelam cinco eixos de análise: a financeirização da educação, o ethos empresarial, a mercantilização da educação, o balcão de negócios e a produção do sujeito neoliberal. Destaca-se a ênfase em medidas de eficiência, competição e privatização, em detrimento de horizontes de equidade e inclusão. Este estudo contribui para o mapeamento de processos presentes no sistema educacional sob o ataque neoliberal, destacando a necessidade de políticas que priorizem a justiça social.

Goat milk is a valuable resource for food production thanks to its physical, chemical, and biological properties, easy digestibility, and lower allergenicity. The dairy product market in Kazakhstan is growing, leading to advancements in the industrial processing of goat milk. Consequently, this study aimed to analyse the proximate composition of raw goat milk, produce cheeses from goat milk alone and in combination with cow milk and examine the fatty acid profiles of the resulting cheeses. The findings indicated that goat milk contained a higher percentage of protein, while a 1:1 mixture of goat and cow milk exhibited increased levels of lactose and fat (p <0.001). A soft cheese prepared from goat milk exhibited faster coagulation, higher cheese yield and fat in dry matter. Furthermore, the saturated fatty acid (SFA) content was greater in cheeses made from the goat-cow milk blend compared to those made solely from goat milk (p <0.05). Notably, an increased presence of oleic acid and polyunsaturated fatty acids (PUFAs), such as linoleic, linolenic, and palmitoleic acids, was only detected in 100% goat milk cheeses. Overall, the soft cheese produced from goat milk showed improved nutritional qualities, particularly regarding fatty acid content. However, additional research is needed to assess sensory attributes and consumer acceptance.

Published: September 2024

Food quality and safety are among the most important aspects of the food industry. The object of this study was packaging materials intended for packaging bakery products. One of the key factors for food safety is provided by packaging. The increase in food packaging materials creates a demand for promoting products and brands that are safe for consumption. Food spoilage due to poor-quality packaging causes huge losses not only to businesses but also to consumers. Despite the effectiveness of existing practices, retailers still face many challenges, including the materials used and their possible interaction with food. In addition, the transfer of harmful materials from packaging to food is still an issue. This study presents the results of an assessment of the migration of heavy metals used in different types of food packaging in the Republic of Kazakhstan. Determination of heavy metal migration was carried out in aqueous extract by atomic absorption spectrometry. The practical value of the above research is to study the content of lead, zinc and chromium in the composition of various types of paper food packaging. The assessment of the average migration level of heavy metals following the current requirements revealed that all types of paper contain significant amounts of lead and zinc, which do not meet the requirements for paper intended for food packaging. Thus, specific samples should be considered a potential risk to human health if reused without pre-treatment as a source of recycled cellulose fibre for producing packaging used in direct contact with foodstuffs.
Connectedness of Malaysian Students in Indonesia Through Social Media
Authors: Habibi Muhamad Lutfi , Andini Nur Fadhilah
Published: September 2024

This research identifies the motivation behind the connection between Malaysian students studying at the Faculty of Da'wah and Communication at UIN Sunan Kalijaga Yogyakarta through social media. This research aims to provide recommendations to strengthen positive cooperation in the field of education between Malaysia and Indonesia. Although much research has been conducted on the Malaysian diaspora, this paper is novel by highlighting a specific aspect of the subject that rarely receives attention, namely the diaspora who are still students. Using a case study approach, the qualitative research method uses interviews as a data collection tool based on the Uses and Gratification theory. The research results show that Malaysian students are connected through social media with several motivations, such as diversion, personal relationships, personal identity, and surveillance. They use social media as an escape through culinary content, a means of sharing recommendations for tourist attractions, strengthening religious and national identity, and monitoring current conditions in both Indonesia and Malaysia.
Indonesian Migrant Women Workers in Türkiye and Media Representation at Home: Precarity Works and Mediating the State Protection
Authors: Yanuar Daffa Ramadhani
Published: September 2024

This qualitative study examines the portrayal of Indonesian migrant women workers in Türkiye by major Indonesian online media outlets from 2019 to 2023. Using content analysis, the research explores dominant media representations surrounding workers in Türkiye's care service and tourism sectors. Findings reveal patterns of precarious work, exploitation, and vulnerability to undocumented employment, particularly involving Syrian employers. The study highlights a significant shift in media coverage from sensationalist reporting to echoing government narratives on combating undocumented migration. This shift aligns with Indonesia's labour-export policy reforms under President Jokowi, which aim to promote labour migration to formal sectors and distance the country's image from domestic worker exports. The research demonstrates how media reflects and reinforces state migrant protection policies through "domesticated protection." However, this approach inadvertently perpetuates victimization and potentially exacerbates vulnerabilities by stigmatizing unofficial migration channels. While intended to safeguard workers, stringent regulations may if not already contribute to increased undocumented migration. By analyzing the nexus between media representation, state policies, and migrant precarities, this study contributes to understanding the complex dynamics of labour migration in an emerging corridor, calling for a more nuanced approach to media coverage, policy-making, and future studies that acknowledges both migrant agency and structural challenges.

Впервые получены новые зависимости и взаимосвязи при реализации технологии абразивостойкой наплавки на термоупрочненную сталь 65Г. Выявлен характер распределения твердости по Виккерсу в вертикальном и горизонтальном направлениях области наплавки и показана их идентичность. Установлено, что термические воздействия от сварочной дуги снижают твердость основного металла, расположенного непосредственно в нижней части области наплавки. Показано, что влияние термических воздействий на твердость металла и размеры зоны термического влияния и околошовной зоны больше проявляется по глубине области наплавки по сравнению с плоскостным направлением. Дано объяснение изменений твердости HV в различных зонах на основе материаловедения, металлургии и последних исследований в области прочности.

For the first time, new dependencies and relationships were obtained in the implementation of the technology of abrasion-resistant surfacing on heat-strengthened steel 65G. The nature of the Vickers hardness distribution in the vertical and horizontal directions of the surfacing area is revealed and their identity is shown. It has been found that thermal effects from the welding arc reduce the hardness of the base metal located directly in the lower part of the surfacing area. It is shown that the influence of thermal influences on the hardness of the metal and the size of the zone of thermal influence and the near-seam zone is more pronounced in the depth of the surfacing area compared with the planar direction. An explanation of the changes in HV hardness in various zones is given based on materials science, metallurgy and recent strength studies.

В статье представлены результаты коррозионных испытаний кобальта в атмосферных условиях при различных температурно-влажностных режимах. Показано, что коррозионные потери кобальта при температурах 20, 30 °С и относительной влажности воздуха 70, 80, 95% незначительны. Скорость коррозии кобальта при температуре воздуха 50 °С резко возрастает, особенно при относительной влажности воздуха 95%. Об интенсивном протекании коррозионных процессов на кобальте в этих условиях свидетельствует и внешний вид образцов кобальта: после испытаний при температуре 50 °С и влажности воздуха 70% образцы чернеют, а при температуре 50 °С и влажности воздуха 95% покрываются черными, маслянистыми, легко осыпающимися хлопьями – продуктами коррозии кобальта. Установлено, что на поверхности кобальта образуется коррозионная пленка, состоящая из эвтектической смеси Co–CoO переменного состава и сложного оксида CoO·Co(OH)2·H2O. При повышении температуры коррозионных испытаний поверхностная пленка гидратированного оксида кобальта увеличивает свою толщину, покрывается микротрещинами, формируются хлопья гидроксида кобальта, которые слабо сцепляются с подложкой и осыпаются.

The paper presents results of cobalt corrosion test on the air at different temperatures and humidity values. It was demonstrated that corrosion losses in Co samples at 20, 30 °С and relative humidity of 70, 80, 95% are insignificant, but its corrosion velocity is sharply increased at 50 °С especially at 95% relative humidity. One can also judge the intensity of corrosion processes by the look of the samples: the samples turn black at 50 °С, humidity 70%, and at 50 °С, 95% they are covered with black, oily, easily crumbling flakes – products of cobalt corrosion. It was found that corrosion film on the cobalt surface has a complicated structure that includes the Co–CoO eutectic mixture of variable composition and the complex oxide CoO·Co(OH)2·H2O. With an increase in the corrosion tests temperature, the surface film of hydrated cobalt oxide comes thicker, it becomes covered with microcracks, than flakes of cobalt hydroxide with weakly adhesion to the substrate, and then they deteriorate.

Authors: Khairat Nurul
Published: September 2024

In recent years, YouTube has become an important platform for educational content. While various studies have examined YouTube’s role in improving learners’ English listening skills, much of the earlier research focused on outdated versions of the platform. This study aims to update these findings by analyzing more recent studies and addressing gaps in the literature regarding YouTube’s impact on enhancing English listening skills. The review includes nineteen studies published between 2020 and 2024, with one additional study from 2014, sourced from Google Scholar and the International Journal. The results show that YouTube provides authentic language resources, like podcasts, videos, and interviews, which significantly boost listening comprehension. However, the effectiveness of YouTube as a learning tool depends on the use of effective strategies, including customized playlists, guided viewing, and interactive exercises. The study also identifies challenges such as limited internet access and the necessity of pedagogical oversight to fully utilize YouTube’s benefits. Although YouTube holds promise as a resource for language learning, further research is needed to assess its impact on academic performance and long-term language development. This study offers practical advice for educators looking to incorporate YouTube into their teaching methods.

This article explores China and Russia's cultural diplomacy and soft power approach in Central Asia. Drawing from various sources, including scholarly literature, reports, and expert analyses, our analysis elucidates the strategies employed by these powers. Both states compete for influence through a combination of hard and soft power tools tailored to the diverse geopolitical landscape of the region. While China relies primarily on its vast economic potential as a critical component of its cultural diplomacy to build soft power, Russia leans on its historical socio-cultural ties with the region. The contest for influence between Russia and China in the region extends beyond mere geopolitical maneuvering, permeating into the realm of culture and evolving into a battle for the hearts and minds of the region's public. This competition significantly impacts global power dynamics and the future growth trajectory of Central Asian states. By highlighting the intricacies of these relationships, we aim to contribute to the existing literature on the geopolitical situation in Central Asia from a cultural perspective.
