Catechol is accessible as the basic essential compound of various made organics. It is created from different sources like herbicides, wood added substances, oil enterprises, Cosmetics, pharmaceuticals, medicates, etc. It very well may be eliminated from the industrial effluents by
different ways however best technique is bioremediation. To separate the most potential bacterial strain from soil that can dispose of Catechol from squander water, soil was gathered from the hospital zone. 1gm of soil dissolved into 50 ml sterilized distilled water, serially diluted and transferred
to Petri plates with agar medium and enriched with 500 ppm conc. of Catechol and after 48 hours of incubation, twenty Seven (27) bacterial colonies were secluded and screening was done in liquid medium that was enhanced with 500 ppm of Catechol to pick the most impressive strain. The most
intense strain, S12 had the ability to eliminate almost ~ 93.61% of Catechol within 48 hours, 37 ˚C temperatures and 6.8- 7.2 pH. Then, to optimize the process parameters for its better performance in a batch reactor, six parameters were considered and experiments were performed in those
varying parameters. Those parameters are Temperature, pH of the bacterial medium, volume of the bacterial medium, Incubation time, percentage (%) of inoculums and Initial conc. of Catechol. In the view of morphological, biochemical, nucleotide homology and phylogenetic investigation, the strain
was found to have most extreme likeness (98.63%) with Bacillus pseudomycoides strain NBRC 101232.

O poder democrático do ensino superior: associação entre escolaridade e adesão à democracia na cidade de São Paulo
Authors: Silva Diego Moraes , Kemer Thaíse , Mont’Alverne Camila
Published: May 2023

A educação é frequentemente vista como solução para déficits democráticos, mas seu papel nas atitudes políticas ainda é pouco compreendido. Este artigo investiga a associação entre escolaridade e adesão à democracia em São Paulo. Partindo de uma amostra representativa com 2.417 entrevistas, a análise do contexto paulistano se mostra oportuna para o estudo, já que a cidade é caracterizada por melhores notas em avaliações educacionais e possui relevante histórico de engajamento político. Utilizando modelos hierárquicos de regressão, encontrou-se que a escolaridade é um preditor significativo da adesão à democracia, ao passo que níveis mais altos de escolaridade estão associados a uma maior adesão. Os resultados divergem de achados de outros trabalhos que consideram o Brasil como um todo: ao contrário deles, encontramos que o acesso à educação superior é um fator-chave para a valorização da democracia.

Authors: Andion Carolina , Gonsalves Aghata Karoliny Ribeiro , Magalhães Thiago Gonçalves
Published: May 2023

O Brasil é reconhecido por possuir um marco regulatório avançado em termos de defesa dos direitos da criança e do adolescente, porém os desafios cotidianos para colocá-lo em prática ainda são imensos. Diante disso, como compreender esse gap entre regulação e prática? Este artigo propõe responder essa questão ancorando-se numa perspectiva pragmatista de análise, com a utilização do método da cartografia das controvérsias para o exame dessa política pública. Trata-se de retraçar a trajetória do debate nas arenas públicas que a compõem historicamente, buscando analisá-lo a partir dos principais porta-vozes, argumentos, controvérsias e visões de mundo presentes no debate público. Os resultados evidenciam como a ação pública nesse campo se (re) configura, a partir de processos de disputa e de estabilização, nesses 30 anos, identificando seus avanços e limites. As conclusões do estudo contribuem para identificar os desafios dessa política pública e demonstram que esta ocorre na interconexão de níveis, de formas de regulação e de redes de atores, o que implica uma revisão dos métodos tradicionais adotados na análise de políticas públicas.

Representações da homossexualidade no Espiritismo
Authors: Pereira Francisco
Published: May 2023

Resumo Neste artigo, apresenta-se uma análise do processo de construção das representações da homossexualidade na doutrina espírita brasileira e da percepção de homens gays praticantes do Espiritismo a partir de dados coletados entre os anos de 2016 e 2019, na cidade de Campina Grande, Paraíba. Os resultados apresentados foram frutos de pesquisa realizada, inicialmente, na obra de Allan Kardec e em discursos e publicações de médiuns brasileiros contemporâneos. Após, para alargar o debate, foram realizadas entrevistas com homens gays praticantes do Espiritismo. Levou-se em consideração a Análise do Discurso de linha francesa enquanto vertente teórico-metodológica. Observa-se que as representações apresentadas pelos interlocutores coadunam, em parte, com aquelas pensadas pelos doutrinadores espíritas, mas existem resistências, mostrando que a subjetividade do indivíduo interfere e ajuda a ressignificar conceitos e práticas religiosas. Por meio deste trabalho, portanto, busca-se contribuir para o alargamento do debate em torno da sociologia da religião em interface com a sexualidade e, por fim, expandir o debate em torno do Espiritismo brasileiro.

Published: May 2023

Abstract This study evaluated the influence of heating temperature variability on the degradation level of concrete by varying the exposure temperatures (200°C, 450°C, and 800°C) and concrete design strength (C25 and C40). The concretes were submitted to ultrasound tests (before and after heating) and then were ruptured by axial compression. After rupture, samples were taken from the fracture section of the specimens for microstructural analysis by scanning electron microscope (SEM), and molecular analysis by Raman spectroscopy. The results showed that the residual strength of the concrete can change significantly (values differing by more than 100%) with temperature variability in the oven. There were physicochemical changes in the concrete constituents. The variations in Raman spectra and morphological changes (SEM images) allowed to analyze the variation in the level of degradation of concrete after exposure to fire, at the same firing step, due to temperature variation in the ovens, being compatible with the results of compressive strength and ultrasonic wave propagation velocity (UPV). Thus, the study highlights the need for adequate mapping of the heat in the oven and monitoring of the temperature of specimens in studies of concrete at high temperatures.
Changes of Activity of Energy and Ion Exchange Enzymes and the Energy Substrates Content in Tissues of Perca fluviatilis and Rutilus rutilus under Toxic Water Pollution
Authors: Martseniuk V. M. , Prychepa M. V. , Marenkov O. M.
Published: May 2023

The paper deals with impact of toxic pollution on activity of energy and ion exchange enzymes in roach and perch. Significant changes in content of energy substrates in liver, gills and muscles of perch and roach were established depending on season and toxic load. The glycogen content in liver of perch specimens from the polluted lake (Kyrilivske) was lower than in specimens from the control lake (Babyne). Also, lower activity of SDH in muscles and gills of roach has been established. It should be noted that roach was characterized by higher variability of the studied enzymes' activity. This indicates the species specificity of the metabolic reactions of the studied fishes to counteract toxic pollution.

Authors: Volkova O. M. , Belyaev V. V. , Skyba V. V. , Pryshlyak S. P.
Published: May 2023

The role of helophytes in 137Cs migration into various components of aquatic ecosystems of different types was investigated. It has been found that 74-87% of 137Cs total storage in the phytomass was registered in the underground organs of Phragmites australis and 61-86% - in the underground organs of <i.Typha angustifolia. As a result of dying away of the aboveground organs of helophytes, 5-11% of 137Cs total content in the phytomass can income into the water due to the release of the exchanged forms of the radionuclide. In this case, 8-31% of 137Cs will remain in the detritus. Annually as a result of dying away of the above-ground and underground organs of helophytes, 53-85% of 137Cs accumulated in the phytomass incomes into the bottom sediments. In this case, 9-19% of 137Cs remains in the wintering rhizomes. The activity of 137Cs accumulated in helophytes is not more than 6% of its content in bottom sediments occupied by plant communities. After helophytes dying away, secondary contamination of the water with 137Cs can attain 0.4% of its activity in bottom sediments occupied by plant communities, about 1.1% can income into the detritus, and 4.2% - into the bottom sediments.
PSYCHOLOGICAL SAFETY AND TEAM MEMBER EFFECTIVENESS OF MINORITIZED STUDENTS IN ENGINEERING EDUCATION
Authors: Beigpourian Behzad , Ohland Matthew W.
Published: May 2023

Higher psychological safety (i.e., a common feeling among team members to take interpersonal risks
without any fear of negative consequences) is related to increased learning in teams, yet there is no comprehensive study in engineering education to see how individual and team-average psychological safety are related to students' team experience, and particularly how that relationship differs based on gender, race/ethnicity, citizenship status, previous programming skills, attended semester,
and students' GPA. This study addresses these questions using multi-linear regression and multi-level
modeling. Individual psychological safety was significantly related to racial/ethnic identifications of
Asian, "Black, African-American" (a single choice as presented to students), and Hispanic/Latino,
being an international student, attended semester, and GPA. Team member effectiveness was significantly
related to GPA, previous programming skills, attended semester, a racial identification of Black,
African-American, and team-average psychological safety. The results of this study help engineering instructors understand what is happening in teams and add to our knowledge about the team experiences of minoritized students.
Peacebuilding in the Anthropocene: Negotiating the Problems of Acting in an Entangled World
Authors: Lakitsch Maximilian
Published: May 2023

The performance of international peacebuilding has been far below the high expectations set after the end of the Cold War. Criticism of the modernist conviction that it is possible to build peace along the lines of universal and linear blueprints has accompanied peacebuilding ever since its inception. this critique has gained depth and significance within the broader context of the Anthropocene. This 'intervention' article focuses upon two important publications in this field: Ignasi Torrent’s Entangled Peace: UN Peacebuilding and the Limits of a Relational World (2021) and Jan Pospisil’s Peace in Political Unsettlement: Beyond Solving Conflict (2019). Both monographs highlight that a reconsideration of peacebuilding in the Anthropocene is necessary and search for ways to engage with peacebuilding more effectively and more realistically. However, they also indicate a fundamental problem of how to work in this field without assumptions of linear causal impacts. Based on a through analysis of Torrent's and Pospisil's understandings of peacebuilding practice, this article introduces and scrutinizes the dilemma that arises from the need to reject narrow and instrumentalist approaches in the entangled world of the Anthropocene while maintaining that it is nevertheless necessary to navigate peace and still to act in this world.

According to a widely shared perception, international peace and security law is in crisis. Yet it often remains unclear what the constitutive features of this crisis are, how novel it really is, and what its sources, forms, and effects are. In the introduction to this symposium, we unpack the current crisis narrative by focussing on norm contestation in the law against war: Which norms are contested? Who are the actors that contest these norms and how? What are the effects of these contestations on peace and security law as a whole? To answer these questions, we draw on recent scholarship on illegality in Public International Law (PIL) and on contestation in International Relations (IR); we propose an interdisciplinary analytical framework that distinguishes between applicatory, legislative, and systemic contestation. Challenges to the application of norms and the factual basis are a common theme in legal disputes that specify international norms. Legislative contestation challenges the content of norms on a more abstract level, aiming to change its boundaries. Systemic contestation fundamentally questions the cornerstones of the international order. This typology invites PIL and IR scholars to study how different forms of contestation shape international norms in the law against war.
A travessia das adolescências: uma análise psicanalítica da obra “A Viagem de Chihiro”
Authors: Hamada Arisa , Castro Maria Luiza Sarno
Published: May 2023

INTRODUÇÃO: A adolescência assume diferentes concepções a depender da época vivida, sendo importante refletirmos sobre essas diversas leituras. Entretanto, o foco do presente trabalho está voltado para a abordagem da psicanálise que propõe ler esse momento como uma travessia, o momento de transição para a adultez, marcada pelo surgimento de caracteres sexuais secundários e psíquicos que repercutem no encontro com o desconhecido. O filme A viagem de Chihiro conta a história de Chihiro Ogino, uma menina de dez anos que está mudando com os pais para uma nova cidade. Tomando o filme como uma metáfora do adolescer na contemporaneidade, o presente trabalho busca apreender os impasses da adolescência através da trajetória vivida pela personagem Chihiro. Para o desenvolvimento do estudo, a metodologia escolhida foi a pesquisa documental. METODOLOGIA: Para a articulação entre o filme e o tema da pesquisa foi realizada a construção de três eixos de leitura: os lutos inerentes ao processo de adolescência; a adolescência e o tempo lógico de Lacan e os impactos do discurso capitalista na adolescência contemporânea. DISCUSSÃO E RESULTADOS: A viagem percorrida por Chihiro representa o seu adolescer, o qual é marcado por diferentes lutos. Aos poucos, Chihiro vivencia a perda da posição infantil, também, pelas diversas novas responsabilidades que surgem na sua vida, tais como a necessidade de salvar os seus pais, aprender o funcionamento da casa de banho e lidar com as diferentes criaturas nesse novo dia a dia. Os pais da infância, que eram sinônimo de proteção e segurança, gradativamente e dolorosamente se tornam frágeis, levando Chihiro a elaborar uma outra posição subjetiva, tornando-se adulta. CONSIDERAÇÕES FINAIS: A leitura psicanalítica possibilitou um olhar para a singularidade de tal vivência, mostrando os diversos aspectos em jogo que não podem ser limitados aos parâmetros biológicos.
THE PHENOMENON OF WAR: MATERIALISTIC PHENOMENOLOGY POINT OF VIEW
Authors:   Taras Shevchenko national University of Kyiv, Prykhodko Volodymyr
Published: May 2023

The article is devoted to the postphenomenological approach to the study of war as primarily a world phenomenon, anthropological patterns and moral and legal codes. The foundations of the proposed materialistіс phenomenology have three main points. First, existential topography acts as a leading descriptive method which is based on the triple unity of spatiality, bodility and otherness. Secondly, the visibility of the phenomenon is captured by its imagery, which has three situational aspects – givenness, performance practices, marking contours. Thirdly, phenomenality has two asymmetrically connected sides – available, which ensures meeting and assimilation in the approach, and the reverse, which marks the contours of the visible in the invisibility of the distant. The materialistic character of phenomenology means that the emphasis is on the world as an existential media that has its own bodily organized agent network. The description of the war phenomenon offered in this article stops only at the first step – the discovery of givens to testify to a phenomenological point of view, but with the prospect of further description. War manifests itself as a deforming topos compression that leads to bodily practices of concealment. Deformation is the result of homogenizing control over the topos diversity of existence through the invasion of radical otherness that carried out by the artificial corporeality of weapons and the dominant corporeality of the military. In a situation of war, otherness, instead of receding into the invisible, which ensures the absolute difference of the world order, turns into a positive approximation of indistinction, monstrosity. The world stops reporting on the order of life.
MAIN FEATURES OF THE HISTORICAL AND PHILOSOPHICAL NARRATIVE OF EARLY AMERICAN PHILOSOPHY
Authors:   Taras Shevchenko national University of Kyiv, Sobolievskyi Yaroslav
Published: May 2023

It was determined that in modern Ukrainian humanitarianism there is a revival of interest in the formation and peculiarities of national philosophical traditions. It was revealed that one of the leading trends of modern historical and philosophical science is the ever deeper consideration of the cultural, political and social contexts of philosophizing. The growing interest in national philosophies is demonstrated on the example of the study of early American philosophy, which after Americans reinterpreted their own history, as well as culture, politics, philosophy in the second half of the 20th century addressed early American culture, early political ideas, and early American philosophy. For the first time in the Ukrainian intellectual environment, the essential features of early American philosophy are comprehensively outlined in a historical-philosophical retrospective, a wide field of philosophical problems is demonstrated. The narrative that exists in scientific circles regarding the main essential features of the historical-philosophical phenomenon of "early American philosophy" has been studied. Keywords: history of philosophy; American philosophy; early American philosophy; Puritanism; historical and philosophical narrative.
Machine Learning for Network Security: An Analysis of Intrusion Detection Systems
Authors: Kumar Indrajeet
Published: May 2023

Due to the increasing importance of data and communication over computer networks, securing the network has become a critical issue. One of the most common factors that attackers use to bypass security measures is the availability of Intrusion Detection System (IDS) techniques. This paper aims to introduce machine learning to help improve the capabilities of IDS. The paper explores the potential of machine learning to enhance the security of networks. It starts by introducing network security and IDS, and then it reviews the current limitations of IDS techniques. It then delves into the world of machine learning and its applications in IDS. The paper presents an overview of the various aspects of machine learning-based IDS, including the datasets used for analysis, the models used, and the evaluation metrics that were utilized to measure their effectiveness. It then compares the results with traditional IDS techniques, and it explores the potential of this technology for future research. According to the findings of the study, machine learning-based intrusion detection systems can provide an efficient and accurate method of detecting unauthorized access to a computer network. The paper concludes by discussing the technology's potential for securing networks.
Correlates and Predictors of NT-proBNP in Life Insurance Applicants
Authors: Rigatti Steven J. , Stout Robert
Published: May 2023

Objectives.—To document the various laboratory and demographic/historical correlates of NT-proBNP levels in applicants for life insurance, and to explore the accuracy of a prediction model based on those variables.

Method.—NT-proBNP blood test results were obtained from 1.34 million insurance applicants between the age of 50 and 85 years, beginning in 2003. Exploratory data analysis was carried out to document correlations with other laboratory variables, sex, age, and the presence of relevant diseases. Further, predictive models were used to quantify the proportion of the variance of NT-proBNP, which can be explained by a combination of these other, easier to determine variables.

Results.—NT-proBNP shows the expected, negative correlation with estimated glomerular filtration rate (eGFR) is markedly higher in those with a history of heart disease and is somewhat higher in those with a history of hypertension. A strong, unexpected, negative correlation between NT-proBNP and albumin was discovered. Of the variables evaluated, a multivariate adaptive regression spline (MARS) model automated selection procedure selected 7 variables (age, sex, albumin, eGFR, BMI, systolic blood pressure, cholesterol, and history of heart disease). Variable importance evaluation determined that age, albumin and eGFR were the 3 most important continuous variables in the prediction of NT-proBNP levels. An ordinary least squares (OLS) model using these same variables achieved a R-squared of 24.7%.

Conclusion.—Expected ranges of NT-proBNP may vary substantially depending on the value of other variables in the prediction equation. Albumin is significantly negatively correlated with NT-proBNP levels. The reasons for this are unclear.

The skin plays an important role in vitamin D synthesis, humoral balance, temperature regulation, and waste excretion. Due to the complexity of the skin, fluids loss, bacterial infection, and other life-threatening secondary complications caused by skin defects often lead to the damage of skin functions. 3D bioprinting technology, as a customized and precise biomanufacturing platform, can manufacture dressings and tissue engineering scaffolds that accurately simulate tissue structure, which is more conducive to wound healing. In recent years, with the development of emerging technologies, an increasing number of 3D-bioprinted wound dressings and skin tissue engineering scaffolds with multiple functions, such as antibacterial, antiinflammatory, antioxidant, hemostatic, and antitumor properties, have significantly improved wound healing and skin treatment. In this article, we review the process of wound healing and summarize the classification of 3D bioprinting technology. Following this, we shift our focus on the functional materials for wound dressing and skin tissue engineering, and also highlight the research progress and development direction of 3D-bioprinted multifunctional wound healing materials.
