Authors: Fu Chujun , Zhao Jiankun , Yan Baofeng , Zhao Lei , Zhao Zijian
Published: September 2024

To study the effect of pollution accumulation on flashover voltage for composite insulators in western Inner Mongolia, COMSOL software was used to simulate the impact of non-uniform pollution deposition, different particle sizes, varying pollution severity levels, and different wind directions on the amount of accumulated pollution and the flashover voltage of composite insulators. The results indicate that after passing through the composite insulator, pollution particles accumulate to varying degrees on the surface, mainly concentrated at the edges of the insulator shed and the ridges of the skirt. The larger the particle size, the more pollutants accumulate on the composite insulator, which leads to a higher degree of distortion in the surface electric field. The accumulation of pollutants under oblique wind conditions is higher than that under horizontal wind conditions, and the lower skirt position of composite insulators is more prone to accumulation. The non-uniform distribution of pollution on composite insulators leads to an uneven distribution of the surface electric field upon energization, thus reducing the flashover voltage of the composite insulator and making it more susceptible to flashover incidents.

Study on the Characteristics of Low-level Jets in Short-term Heavy Rainfall under the Influence of Northeast Cold Vortex in Shenyang Based on Wind Profile Radar
Authors: Ban Weilong , Zhao Xuan , Wu Yutong , Jiang Shan
Published: September 2024

To enhance the understanding of the mechanisms behind heavy rainstorms influenced by the northeast cold vortex in Shenyang, we analyzed the intensity, height, and index of low-level jets during short-term heavy rainfall events from May to September between 2017 and 2021. The findings are as follows: (1) The maximum wind speed below 2 km generally follows a normal distribution, with low-level jets already present prior to approximately 30% of the heavy rainfall events. The maximum wind speed at corresponding percentiles shows a slight increase as the rainstorm approaches. However, the frequency of low-level jets decreases, and wind speeds significantly drop during the rainstorm. (2) The height distribution of low-level jets increases with altitude, reaching its lowest point 2 to 3 hours before the onset of heavy rainfall. At this time, low-level jets exhibit their strongest and most vigorous development. Combined with the warm, moist air from the southwest providing moisture and thermal energy, these conditions can trigger the onset of heavy rainstorms. (3) The hourly distribution of the low-level jet index (I) remains relatively consistent leading up to a rainstorm. As the rainstorm nears, wind speeds decrease, and the minimum height of low-level jets rises, resulting in a decrease in the low-level jet index (I).

Társadalmi vállalkozások Magyarországon
Authors: Kiss Julianna
Published: September 2024

A társadalmi vállalkozás (social enterprise) fogalma az 1990-es évek második felében jelent meg Magyarországon; a civil társadalom, nonprofit szektor és szociális gazdaság szélesebb körben ismert fogalmaihoz kapcsolódva. A kifejezést sokáig kevesen használták, azonban a 2010-es években elsősorban az Európai Unió prioritásai és az újonnan elérhető támogatási források miatt egyre jobban elterjedt hazánkban is. A téma iránti tudományos érdeklődés és az általános helyzetképet, valamint egyes specifikus részterületeket vizsgáló kutatások száma az elmúlt években szintén megnövekedett. A terület szakirodalmának átfogó elemzése, összefoglalása azonban eddig nem történt meg. Jelen cikk e hiányt pótolva a társadalmi vállalkozások magyarországi helyzetéhez kapcsolódó szakirodalom szisztematikus áttekintését nyújtja a terület tudományos eredményeinek összegzése és a lehetséges jövőbeli kutatási irányok azonosítása céljából.

Hazai egyetemi közösségi szerepvállalási gyakorlatok a társadalmi igazságosság lencséjén keresztül
Authors: Málovics György
Published: September 2024

Napjainkban az egyetemek irányába alapvető társadalmi elvárás, hogy bizonyítsák társadalmi hasznosságukat. Ennek egyik lehetséges eszköze az egyetemi közösségi szerepvállalás megközelítése, amelynek értelmében az egyetemek egyetemen kívüli szereplőkkel működnek együtt olyan módon, hogy az mindegyik félnek kölcsönösen hasznos, és gazdagítja az egyetemek főtevékenységeit. Tanulmányomban a hazai, társadalmi igazsági megközelítésű egyetemi közösségi szerepvállalási kezdeményezésekkel foglalkozom. Félig strukturált egyéni mélyinterjúk elemzése alapján mutatom be azon gyakorlatokat, amelyek mentén a hazai akadémiai szféra egyes szereplői kapcsolódnak nem-akadémiai szereplőkhöz (közösségekhez, civilszervezetekhez, egyénekhez) a társadalmi igazságosság és fenntarthatóság ügyének előmozdítása érdekében, az egyetem első két missziójához (oktatás, kutatás) is kapcsolódóan. Következtetésem, hogy bár e megközelítés a gyakorlati megvalósítás szintjén hazánkban (sem) nevezhető általánosan elterjedtnek, a hazai gyakorlat mégis sokszínű képet mutat. A hazai egyetemi közösségi szerepvállalási kezdeményezések sokkal inkább a társadalmi igazsághoz kapcsolódnak, mint a környezeti fenntarthatósághoz, és mind az egyetemi oktatás, mind pedig az akadémiai-jellegű kutatás módját és célját megváltoztatják: megjelennek e tevékenységek esetében a konvencionális akadémiai közegben jellemzően hiányzó demokratikus működés, sokszínűség és társadalmi hatásosság szempontjai.

A importância do conhecimento anatômico e da técnica de execução para otimização dos resultados do treinamento de força: artigo de opinião
Authors: de Oliveira Chaves Tiago , Silva Reis Michel
Published: September 2024

Strength training is essential for maintaining and optimizing health and is an effective non-pharmacological resource in the treatment of various comorbidities. The repercussions revolve around the promotion of motivated adaptations due to the planning and structuring of the training program through the manipulation of variables such as intensity, volume, selection and order of exercises, weekly frequency, cadence, and amplitude. These include the manipulation of variables such as intensity, volume, exercise selection and order, recovery interval, weekly frequency, cadence, and amplitude. This study aims to discuss the importance of anatomical knowledge and the use of an appropriate execution technique, which must be applied in strength exercises. However, what can be observed in practice is a lack of methodology, as well as an undefined movement standard of exercises, which is based on the premise of improving body composition. In this context, the study points to the need for a more robust discussion on the movement standard and the application of an adequate execution technique in three exercises commonly prescribed in physical training programs. Implementing a proper execution technique based on origin, muscle and joint insertion and actions could optimize strength, hypertrophy, and weight loss results. And, since improving these components is related to a reduction in comorbidities, there is a need for studies that discuss the role of movement execution in greater depth. Thus, further research could evoke a debate on the feasibility of incorporating execution technique as the eighth variable in muscle strength training. Keywords: Physical exercise; physical training; body composition.
Um protocolo seguro de ventilação mecânica invasiva individualizada para pacientes acometidos pela covid-19 pode minimizar riscos cardiovasculares e reduzir a mortalidade: artigo de opinião
Authors: Ribeiro da Silva Roberto , da Costa Silva Leonardo , Silva Reis Michel
Published: September 2024

Coronavírus é uma família de vírus causadores de infecções respiratórias. Foi descoberto na China, em dezembro de 2019, um novo Coronavírus, causador da coronavírus disease 2019 (COVID-19). Os pacientes com COVID-19 podem apresentar quadros assintomáticos a muito graves. Na sua fisiopatologia parece haver um papel importante do componente vascular e da perfusão pulmonar e seu tratamento ideal ainda é pouco conhecido. Os tratamentos utilizados em pacientes graves com COVID-19 podem trazer graves repercussões cardiovasculares. Sabe-se que cerca de 20% dos pacientes com a forma grave da COVID-19 evoluem com lesão miocárdica, 10% evoluem com miocardite e 10% a 30% evoluem com choque, e que os pacientes críticos necessitam muitas vezes de terapias medicamentosas combinadas e ventilação mecânica invasiva, aumentando os riscos para distúrbios cardiovasculares e eletrolíticos, além do aumento do risco de morte. Percebeu-se que a pneumonia da COVID-19 apresenta uma forma atípica de SDRA. A COVID-19 é uma doença sistêmica que agride consideravelmente o endotélio vascular, gerando importante desconforto respiratório. Nota-se que os pacientes que desenvolvem a forma grave da COVID-19 e necessitam de suporte ventilatório invasivo apresentam taxas de mortalidade bastante elevadas. Esses pacientes necessitam de configurações de ventilação mecânica invasiva (VMI) e estratégias de gerenciamento individualizadas e únicas para cada fenótipo. A utilização de estratégias ventilatórias adequadas, através de protocolo individualizado de VMI, pode minimizar a progressão da lesão pulmonar. Entendemos que estratégias ventilatórias combinadas, através de um protocolo individualizado de VMI, podem reduzir riscos cardiovasculares, além de gerar melhores resultados nos desfechos de mortalidade na UTI. Palavras-chave: Covid-19; coronavírus; sars-cov2; ventilação mecânica; doenças cardiovasculares.

Introdução: O esporte competitivo nem sempre é sinônimo de equilíbrio no organismo, podendo influenciar de forma direta o estado nutricional dos atletas. Além disso, em partidas de basquete, devido à realização de movimentos de alta intensidade, o atleta tem redução de líquido corporal, e esta perda hídrica pode induzir a desidratação. Objetivo: Analisar o perfil nutricional e o estado de hidratação em atletas de basquete. Métodos: A pesquisa foi desenvolvida com dois times de basquete de ambos os sexos com idade entre 18 a 47 anos, na cidade de Teresina-PI. Para análise do perfil nutricional foram avaliados dados como altura, peso, dobras cutâneas e gordura corporal, e foram coletadas ingestão hídrica durante o treino, coloração da urina e taxa de sudorese desses atletas. Resultados: Os atletas masculinos apresentaram peso, altura e IMC maiores e percentual de gordura menor quando comparados às atletas femininas. Se apresentaram hidratados, contudo, a coloração da urina apontou desidratação leve entre a maioria dos atletas, a taxa de sudorese e perda de peso foi menor nos homens do que nas mulheres. Conclusão: Verificou-se diferenças físicas entre ambos os sexos, essa variabilidade destaca a importância de considerar não apenas a individualidade de cada atleta, mas suas necessidades individuais de hidratação, independentemente do sexo. Palavras-chave: estado nutricional; estado de hidratação; atletas; basquetebol; desidratação.
Doença celíaca refratária: uma revisão integrativa
Authors: Marques Rodrigues Fernanda , Ferreira Correa Fernanda , Sala Kobal Priscila
Published: September 2024

Introdução: A doença celíaca (DC) é uma enteropatia crônica imunomediada do intestino delgado, caracterizada por perfis sorológico e histológico específicos, impulsionados pela ingestão de glúten por indivíduos geneticamente predispostos. O processo inflamatório leva à atrofia das vilosidades da mucosa do intestino delgado. A doença celíaca não responsiva (DCNR) é identificada pela referida atrofia diante da ineficácia do tratamento dietético estrito. A persistência deste quadro por mais de 12 meses define a doença celíaca refratária (DCR). Objetivo: apresentou-se as características da DCR. Métodos: revisão integrativa de literatura baseada em artigos indexados nas bases de dados SciELO, BVS e MEDLINE/PubMed, publicados entre 2012 e 2022, com os descritores “doença celíaca refratária” e “doença celíaca” em português, inglês e espanhol. Resultados: foram selecionados 15 estudos que descreveram os subtipos, etiologia, fisiopatologia, epidemiologia, sinais e sintomas, diagnóstico e tratamento da DCR. A DCR tem etiologia multifatorial, resultante da interação entre fatores ambientais, genéticos e imunológicos. A fisiopatologia se baseia na imunidade e a desnutrição é um sintoma crônico. O tratamento se fundamenta na dieta sem glúten somada a terapias farmacológicas. Conclusão: a identificação da DCR requer melhores ferramentas diagnósticas. As terapias adjuvantes ao tratamento dietético apresentam resultados pouco satisfatórios. Palavras-chave: Doença celíaca; Dieta livre de glúten; Glutens.

Introdução: O estado nutricional é alterado em idosos com doença de Alzheimer (DA). Objetivo: Avaliou-se o estado nutricional de idosos diagnosticados com doença de Alzheimer. Métodos: Estudo transversal, descritivo-exploratório, aprovado pelo CEP/CONEP nº 3.248.561 conduzido com 10 indivíduos de ambos os sexos, com idades entre 65 e 99 anos de uma instituição filantrópica. Os parâmetros antropométricos utilizados: peso, altura, circunferências da cintura e braço, e Índice de Massa Corporal (IMC). Resultados: Os idosos com a doença de Alzheimer apresentaram média de idade de 81,3 ± 9,7 anos, sendo que 60% (6) eram do sexo feminino. A média de altura foi de 1,63 ± 0,08 m, e o IMC médio foi de 21,06 ± 5,44 kg/m². Em relação à circunferência da cintura 50% (2) dos idosos do sexo masculino apresentaram risco elevado e 50% (3) do sexo feminino apresentaram risco muito elevado para doenças cardiovasculares. Conclusão: Os idosos institucionalizados com doença de Alzheimer apresentam baixo peso, risco de doenças cardiovasculares e redução de massa muscular.

Published: September 2024

Introdução: O bioma Caatinga é potencialmente biodiverso, com destaque para os frutos umbu (Spondias tuberosa Arr.) e cajá (Spondias mombin L.), porém, o consumo destes é pouco explorado, especialmente na alimentação institucional. Objetivo: O presente estudo tem a finalidade de reunir informações na literatura sobre o potencial nutricional e tecnológico do umbu e do cajá e contribuir com estratégias para fomentar o consumo e a produção sustentável desses alimentos. Métodos: Foram selecionados artigos em inglês e português, entre 2002-2022, nas bases de dados Pubmed, ScienceDirect e Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs), utilizando descritores para cada fruto e excluídos artigos duplicados e que abordavam estudos com folhas, extratos, árvores do umbuzeiro e cajazeira, resultando em 23 artigos para a leitura e análise completa. Resultados: Os frutos apresentaram valores significativos de fibras, vitaminas, minerais, fitoquímicos e carotenóides. Além de potencial para o desenvolvimento de novos produtos alimentícios, especialmente farinhas. No entanto, percebe-se uma lacuna quanto à avaliação do consumo alimentar desses frutos e sua inserção na alimentação institucional coletiva, fatores que certamente promoveriam a inclusão de alimentos da biodiversidade nos cardápios, fortalecendo a produção, cultura e economia locais. Conclusão: As estratégias para a produção sustentável dos frutos seriam promover técnicas de cultivo, informar agricultores familiares sobre o potencial nutricional gastronômico e a valorização do uso tradicional dos frutos; e, para fomentar o consumo, enfatizamos a educação alimentar e nutricional, o desenvolvimento de preparações para a alimentação escolar e a realização de oficinas culinárias.
