Surface roughness is one of the parameters of product quality, that’s why the research of cutting mode impact on surface roughness is a current topic. The diversity of cutting tools and materials to be worked leads to the need for more detailed study of the impact of cutting modes on surface roughness.Previous researches have established that the radius of curvatureof cutting tool and the cutter feed have an impact on surface roughness. There are also studies for assessing cutting speed and cutting depth effects on surface roughness. But these studies are not complete and exhaustive, because they have been done for selected materials, cutting tools and cutting modes.The aim of the research described in the article is a scientific inquiry of cutting mode impact on surface roughness in turning of chromium-molybdenum steel 38ХМand the search for optimal cutting modes for this steel.The mathematical relationship between surface roughness and cutter feed, cutting depth, cutting speed was written in the form of power function. The range of variation was chosen. Regression coefficients were defined on the methodology of full factor experiment of type 23. The constructed mathematical model has been checked for adequacy. The equation of surface roughness dependence on cutting mode in turning of 38ХМsteel was obtained.Finding the best possible combinations of cutter feed, cutting depth, cutting speed values for turning of 38ХМsteel was undertaken using the Taguchi method. It was based on the search for technological modes in which the evaluated quality parameter is least affected by uncontrolled factors.As a result of the research it is established that cutting speed and cutting feed have the greatest impact on surface rough-ness. It is also shown that cutting depth has a negligible impact on surface roughness. It is proved that the machining processed at small cutting depthand small feed and large cutting speed is most appropriate. The optimal cutting modes for turning, providing minimal surface roughness are determined.Thus, the complex use of full factor experiment method and the Taguchi method made it possible not only to obtain the equation for the dependence, but also to determine optimal cutting modes.

Published: May 2024

Aqueous organic redox flow batteries (AORFBs) are a promising solution for the large-scale storage of renewable energy. These systems store electricity via electrochemically active organic molecules in an aqueous solvent, which offers superior safety and renewability compared to organic solvents. Furthermore, AORFBs provide a cost-effective alternative to aqueous vanadium-based redox flow batteries. However, designing molecules with adequate electrochemical properties that are also soluble in water and stable during long-term cycling remains a challenge. In this study, we investigate the impact of PEGylation as a potential solution to address these issues. A simple and efficient synthetic approach was used to prepare PEG-containing viologens, with different chain lengths, counterions and symmetries. Their physical and electrochemical properties, including solubility, viscosity, redox potential and heterogeneous electron transfer rate constant, were studied. The results demonstrate that PEG chains enhance solubility in water, and that the chloride counterion increases solubility by 25% compared to the tosylate counterion. None of the studied modifications had a significant impact on the electrochemical properties, demonstrating the usefulness of N-substitution in tuning the solubility without compromising the use of the viologens as negolytes. Although asymmetric derivatives yielded higher solubilities (up to 2.7 M), the most stable organic negolyte under cycling conditions at high concentration (1 M) was a symmetric viologen containing two PEG units (12 days with 0.29% of capacity loss per day). Therefore, the PEGylation of organic molecules represents a valuable approach to improving the aqueous solubility of electrolytes for use in aqueous organic redox flow batteries.
Versatile Deacylative Cross-coupling of Aromatic Ketones

Published: May 2024

Transition metal-catalyzed cross-couplings represent the most dependable techniques for linking aryl electrophiles with nucleophiles to synthesize a diverse array of valuable aromatic compounds. While aromatic ketones are crucial intermediates in the synthesis of aromatic compounds with numerous known methods for carbonyl transformations and aromatic ring modifications, few consider them as aryl electrophiles suitable for cross-coupling. This is primarily because forming new bonds with nucleophiles requires the cleavage of a strong C–C bond. Herein, we introduce a cross-coupling method that effectively utilizes aromatic ketones as versatile aryl electrophiles. The cornerstone of our strategy is the transformation of aromatic ketones into aromatic esters via sequential Claisen and regioselective retro-Claisen condensations. The resulting esters are then capable of undergoing reactions with various nucleophiles in a one-pot process.

Published: May 2024

Organocatalysis has established itself as a third pillar of homogeneous catalysis, besides transition metal catalysis and biocatalysis, as its use for enantioselective reactions has gathered significant interest over the last decades. Concurrent to this development, machine learning (ML) has been increasingly applied in the chemical domain to efficiently uncover hidden patterns in data and accelerate scientific discovery. While the uptake of ML in organocatalysis has been comparably slow, recent years have shown an increased interest in the community. This review gives an overview of the work in the field of ML in organocatalysis. The review starts by giving a short primer on ML for experimental chemists, before discussing its application for predicting the selectivity of organocatalytic transformations. Subsequently, we review ML employed for privileged catalysts, before focusing on its application for catalyst and reaction design. Concluding, we give our view on current challenges and future directions for this field, drawing inspiration from the application of ML to other scientific domains.
Avaliação Ambiental Integrada do Instituto Central de Ciências da Universidade de Brasília – ICC
Authors: Romero Marta Adriana Bustos
Published: May 2024

Este livro taz uma Avaliação Ambiental Integrada do Instituto Central de Ciências (ICC) da Universidade de Brasília (UnB), para instrumentar seu Plano de Reordenamento físico de 2005, que visava à manutenção do espaço icônico, apto para atender as necessidades do momento e do futuro. Sendo as universidades organizações complexas, cuja permanência depende de sua capacidade de se adaptar a mudanças rápidas do meio ambiente, aumenta o interesse pela ideia de flexibilidade, que, no caso do ICC, traduz-se pela independência da estrutura em relação às atividades desenvolvidas no seu interior. Tendo em veista que a motivação essencial dos planejadores da UnB era de que os institutos centrais e também as faculdades deveriam ser lugares de atividades criadoras, não abmientes de ensino, Oscar Niemeyer decidiu reunir boa parte deles num único edifício, capaz de acomodar qualquer programa de utilização. Sua estrutura básica mostra-se, portanto, perene e imutável, em oposição ao caráter transitório dos espaços organizados sob sua proteção. É na arquitetura do ICC que os diferentes conceitos de abertura formal parecem se ecnontrar, e os espaços resultam fluidos, vibrantes, imponderáveis, sendo exemplarmente vivenciados e ocupados. De fato, seus pórticos não apenas parecem prolongar indefinidamente no espaço, como se prestam às mais imprevisíveis e diversificadas formas de apropriação individual. Niemeyer transformou o ICC em um elemento estruturador do campus, o que contribuiu para a criação da atmosfera do lugar, onde o projeto cria laços, não fica isolado na paisagem e sinaliza o caráter urbano do campus.

DESENVOLVIMENTO PROFISSIONAL DOCENTE EM CONTEXTOS DE INCERTEZAS: INQUIETAÇÕES E PROBLEMATIZAÇÕES
Authors: Moreira Cruz Lilian , Gracia Ferreira Lúcia
Published: May 2024

Este artigo tem como objetivo problematizar o Desenvolvimento Profissional Docente – DPD, tendo como pano de fundo algumas inquietações advindas do campo político e do contexto da pandemia da Covid-19. Para isso, assentamos a pesquisa em uma abordagem qualitativa, sendo do tipo descritiva exploratória. Nesta direção, fizemos um recorte temporal, tendo o início a Constituição Federal de 1988 até o contexto pós-pandemia, ou seja, analisamos um movimento de 34 anos de algumas conquistas e perdas dos/as profissionais da educação brasileira, para isso, nos debruçamos nos marcos legais e discussões teóricas de estudiosos/as como Tardif (2014), Ferreira (2014; 2020), Cruz, Barreto, Ferreira (2020), Marcelo Garcia (1999; 2009), Day (2001; 2005), Oliveira-Formosinho (2009), Imbernón (2009; 2011), Vaillant (2014) etc. Os dados revelam que durante a pandemia, os/as professores/as foram impactados não apenas pela crise sanitária, mas também por uma crise política. Na primeira, faltou suporte pedagógico, tecnológico, humano, político, social, financeiro, psicológico, entre outros.  Essa carência resultou em implicações negativas para o DPD, incluindo o adoecimento dos/as professores/as diante das exigências das aulas remotas e do aumento da carga de trabalho. Na segunda, observamos a perda de autonomia devido às reformas educacionais, a falta de formação contínua em tecnologia e a erosão salarial devido à inflação, entre outros desafios. Como resultado, o DPD foi afetado por uma combinação de fatores oriundos de contextos políticos, sociais, econômicos e organizacionais, resultando na precarização do trabalho docente e desencadeando processos de desprofissionalização e proletarização dos/as professores/as. Portanto, torna-se evidente a necessidade crucial de adotar políticas públicas educacionais para apoiar os professores e minimizar os danos durante cenários de crises. Oferecer suporte direto às atividades dos/as professores/as em circunstâncias adversas pode ser considerado uma estratégia eficaz para mitigar os efeitos negativos dessas situações, as quais tendem a comprometer os processos de DPD.

Published: May 2024

Este texto busca discutir a política de avaliação instituída a partir do Plano de Desenvolvimento da Educação – PDE que considerou o Índice de Desenvolvimento da Educação Básica – IDEB, como um mensurador de qualidade educacional, e como este reverbera no cotidiano escolar e das pesquisas educacionais no âmbito das universidades. Nesse sentido, incialmente buscou-se nos documentos oficiais a compreensão do modo como essa política foi gestada e implantada na educação brasileira; em seguida por meio das contribuições analíticas de Saviani (2009); Richter; Souza (2015); Freitas (2016); Bertagna; Melo (2020); e Richter Vieira (2021) procedeu-se uma discussão sobre os significados e implicações desse modelo de política nas escolas; e por fim, através de uma busca no indexador Redalyc selecionou-se os artigos publicados nos últimos 05 anos, na tentativa de compreender o modo como as pesquisas tem se apresentado no âmbito acadêmico. Como conclusão aponta-se que esse modelo de política tem trazido para a escola a responsabilização pelos resultados, fragmentação do trabalho didático pedagógico dos professores, mudanças no currículo, e, portanto, um distanciamento de um ensino emancipador, sendo substituído pela busca de resultados nos testes padronizados.
O GRIÔ DENTRO E FORA DA ESCOLA: PARA UMA EDUCAÇÃO DECOLONIAL
Authors: Souto Salom Julio
Published: May 2024

A inclusão da perspectiva afro-brasileira na educação formal teve importantes avanços nas últimas décadas, possibilitando inovações pedagógicas para a descolonização da educação. Dentre as mudanças, observamos a presença de mestres griôs nas escolas, introduzindo conhecimentos e procedimentos didáticos oriundos de espaços culturais extra-acadêmicos. O objetivo deste estudo é seguir os griôs dentro e fora da escola, para entender a conexão entre as práticas educativas no espaço formal e os saberes e fazeres ancestrais construídos em espaços tradicionais. Começamos com uma contextualização geral da figura dos griots em contexto africano e a sua crescente presença no Brasil atual, reconstruindo o processo da sua recente proliferação. Depois realizamos um acompanhamento etnográfico das atividades educativas de dois griôs na região metropolitana de Porto Alegre. Durante vários meses, observamos as atividades dos griôs na escola (rodas de conversa, palestras, apresentações teatrais) e fora da escola (encontro de capoeiristas, aulas de yorubá em terreiras de batuque). Os resultados mostram que a vivência extra-acadêmica dos griôs é fundamental na sua atuação escolar. Destaca o estudo das marcas linguísticas africanas no português falado no Brasil e do racismo colonial sem temporalidade linear. A história e cultura africana e afro-brasileira não são abordadas como um frio componente curricular, mas desde a sensibilidade afetiva e a firmeza antirracista, confrontando a inércia colonial de algumas práticas arraigadas no cotidiano escolar. Concluímos que a colaboração dos griôs no ensino formal tem enormes potenciais para descolonizar a educação, desde que articulada com a atuação dos docentes.

Authors: Okongo Fredrick , Riungu Festus , Nzioki Susan
Published: May 2024

Purpose: Government-sponsored Youth Empowerment organisations (GSYEOs) are designed to skill, prepare, and empower the youths toward poverty eradication, formal employment, and self-reliance. However, poverty and unemployment among the youths in Kenya seem to be on an onward trajectory, and yet scarce research has been conducted on the influence of strategic direction on the performance of GSYEOs. This study examines the influence of strategic direction and the performance of GSYEOs in Kenya, which is anchored on strategic leadership theory and measured using the Balance Score Card framework.
Design/Methodology/Approach: A descriptive research design was utilized and a random sample of five GSYEOs with a total population of 1089 employees was adopted, and a sample of 109 was derived. Correlation analysis results show that strategic leadership and organisational performance were positively and significantly correlated (r=0.661; P-value <0.05). Results from simple linear regression showed that 43.6% was a good fit for the organisational performance (R squared =0.436, R= 0.661).
Implications/Originality/Value: The study recommends that GSYEO’s leadership encourage strategic direction implementation through adequate budget allocation.

Yet, scarce research has been conducted on the influence of strategic direction on the performance of GSYEOs. This study examines the influence of strategic direction and the performance of GSYEOs in Kenya, which is anchored on strategic leadership theory and measured using the Balance Score Card framework.
Design/Methodology/Approach: A descriptive research design was utilised, a random sample of five GSYEOs with a total population of 1089 employees was adopted, and a sample of 109 was derived. Simple analysis results show that the relationship between organisational performance and Human Resource Development is statistically significant as (p<0.05), 65.0% of the variation in the organisational performance can be explained by the regression model (R2=0.65, ΔR2=0.644, F(1,64) =118.748, P<0.05).  Results showed that that 65% was a good fit for the organisational performance.
Implications/Originality/Value: The study recommends that the Government of Kenya allocate and prioritise funding for capacity building in Government-Sponsored Youth Empowerment Organizations.

Dissection of the internal carotid and vertebral arteries is the leading cause of ischemic stroke at a young age. It is a rupture of the intima of the artery with the formation of an intrahepatic (intramural) hematoma, leading to stenosis or occlusion of its lumen. The article describes the epidemiology, etiology, pathogenesis, and clinical picture of extracranial artery dissection. The paper presents modern principles of treatment of this pathology.

The use of dual energy computed tomography (DECT) has become widespread in urology, including in the diagnosis of urolithiasis. DECT makes it possible to visualize and differentiate urinary stones of different chemical density and composition from each other. Studies have shown the advantages of DECT not only in the detection, but also in the differentiation of the main groups of urinary stones. At the same time, a number of in vivo studies evaluate DECT as a technique for the high-accuracy differential diagnosis of urate stones. The accuracy of diagnosing urate stones with DECT reaches 92-100%, as confirmed by sensitivity (84.6-98.4%) and specificity (100%).

Objective. To study the impact of radiation therapy (RT) after organ-sparing surgery (OSS) for breast cancer (BC) on quality of life (QoL) in patients over the age of 65 years. Subjects and methods. The investigation enrolled 133 patients with Stage IA BC who underwent OSS. The patients were divided into 2 groups: 1) patients who had received RT after surgical treatment; 2) those who had not. All the patients included in the investigation received adjuvant hormone therapy for ≥5 years. The mean follow-up period was 61.77±20.10 months. QoL was comparatively assessed using the EORTC QLQ-C30 Version 3 and EORTC QLQ-BR23 questionnaires. Results. The scores on functional and symptom scales and those on the EORTC QLQ-C30 V.3 Global health status/QoL were statistically comparable in the examined groups (p > 0.05). Statistically significant differences between the groups were obtained in assessing the EORTC QLQ-BR23 Body image (BRBI). Arm symptoms (BRAS), and Breast symptoms (BRBS) (p0.05). Conclusion. After CCA with and without RT, the patients older than 65 years showed no significant differences in the assessment of QoL using the Global health status/QoL symptom, functional, and BRFU scales. QoL assessment using BRBI, BRBS, and BRAS demonstrated lower scores in the RT group. Thus, it may be concluded that RT does not worsen the overall QoL in patients, whereas it exerts local side effects in the area of irradiated tissues.

Oral tuberculosis (TB) is an extremely rare event in both phthisiatic and dental practice. The paper describes a clinical case of a patient who visited a dental clinic for acute pain. After tooth extraction, the patient was observed to have atypical clinical presentations. Histological examination revealed alveolar socket TB. Further examination diagnosed pulmonary TB in the patient. Dentists recommend that the duration of planned fluorography should be specified for patients. In addition, patients with pulmonary TB should undergo oral cavity sanation to reduce the risk of oral TB.

MOVIMENTOS SOCIAIS E DEMOCRÁTICOS: de que forma podem refletir/contribuir na construção das políticas públicas
Authors: Simioni Leonardo Soares de Sousa Freitas, Carlos Alberto
Published: May 2024

O presente artigo relata a importância dos movimentos sociais e democráticos, e de que forma pode refletir/contribuir na construção das políticas públicas. O objetivo deste trabalho é apresentar de que forma a aplicação dos movimentos sociais e democráticos pode refletir ou contribuir na construção das políticas públicas, com base nos estudos de movimentos sociais. Para tanto, foi necessário realizar uma abordagem metodológica qualitativa, fazendo uso da metodologia de pesquisa bibliográfica sobre o objeto de estudo, para esclarecer eventuais dúvidas ou falta de conhecimento sobre os movimentos sociais e democráticos. Foram realizadas pesquisas bibliográficas, através de livros, artigos de revistas e periódicos especializados, para coletar informações necessárias ao estudo. Após a análise desses indicadores, percebeu-se que a democracia é geralmente definida como um método específico de tomada de decisão, no qual os representantes eleitos são responsáveis perante os cidadãos através de eleições regulares. As características da sociedade brasileira atual são os movimentos sociais que sempre se preocuparam com a democracia, mantendo os governantes responsáveis, mas também em muitos casos defendendo e praticando concepções alternativas de democracia do que as dominantes e representativas. Com a pesquisa foi possível concluir a real contribuição dos movimentos sociais em conjunto com a sociedade.
