Published: August 2024

Objective: In universities, a key challenge is to integrate practical work knowledge with theoretical knowledge to adapt to the changing demands of the labor market and society. In this context, the objective is to explore how the integration of theory and practice in master's programs focused on formative professions can facilitate transformative learning, enabling students to develop critical and reflective competencies applicable in both professional and personal contexts.

Theoretical Framework: The research is grounded in Habermas's theory of communicative action, transformative learning, and training-action-research approaches, addressing concepts such as critical reflexivity, self-formation, and the integration of practical and theoretical experiences.

Method: A qualitative methodology with an action-research design, termed training-action-research, was adopted. Twenty-five students from a master's program in education participated. Data collection involved participant observation and practice analysis, focusing on critical reflection and rational dialogue about work and training experiences.

Results and Discussion: The alternation between theory and practice facilitated the development of reflective and critical competencies in the students. The study highlights implications, identified relationships, discrepancies, and limitations.

Research Implications: The results can enhance teacher training, promote continuous professional development, and implement reflective and critical practices in educational and professional settings.

Authors: Horta Ricardo Augusto dos Santos , Lima Weslley Eunathan Fernandes , Pacheco Tiago de Sousa , Villela Luciana Silva 
Published: August 2024

Objective: This work aims to analyze a sample of the mineral Rutana, composed of two crystalline phases of titanium dioxide (TiO2): rutile and anatase, using the X-ray diffraction technique.

Theoretical reference: In 1914, the German physicist Max von Laue, using a CaSO4 crystal, successfully achieved the diffraction of X-rays. Crystalline solids, such as CaSO4, consist of regular arrangements of atoms with interatomic spacings of the order of 0.1 -1.0Å, that is, with the same order of magnitude as the wavelength of X-rays. Due to the periodic nature of the internal structure of the crystals, it was possible for them to act as a three-dimensional diffraction grating, providing science with a new method for indirect investigation of the internal structure of materials: the X-ray diffraction (XRD) technique.

Methodology: In this technique, a finely ground crystalline powder of a material is placed in the path of a monochromatic x-ray beam. This material, composed of a large number of small crystallites, are randomly oriented. Diffraction occurs from planes of the crystallites that are oriented at the correct angle to fulfill the Bragg condition, in such a way that localized peaks of the same intensity as the diffracted beams are formed.

Results and discussion: Based on the intensity, angles and width of the diffraction peaks, the mass percentages of each of the mineral's crystalline phases were obtained: rutile (62.08%) and anatase (37.92%).

Research Implications: This work presents a contribution to future research related to the chemical characterization of initially unknown samples, by providing a comprehensive and representative theoretical framework related to the XRD technique.

Originality/value: This study presents practical contributions to the literature related to the application of the XRD technique in the characterization of materials.
Analysis of The Efficiency of Public Expenditure on Education in Elementary Education in The State of Alagoas
Authors: Andrade Daniel Mendes de , Souza Júnior Celso Vila Nova de , Moreira Tito Belchior Silva , Constantino Michel 
Published: August 2024

Objective: This article analyzes the efficiency of public spending on education in the municipal public network in elementary education, in all cities in Alagoas, using the data envelopment analysis method, DEA.

Theoretical Framework: The present work used the variable return to scale (BCC) model, since we would be dealing with municipalities with varied realities. There are two basic ways for a unit that is inefficient to become efficient. The first would be to reduce resources (inputs) and keep products constant, which would be an input-oriented orientation; the second would be doing the opposite, increasing the result (products) from the same amount of inputs, an orientation focused on outputs.

Method: The data envelopment analysis method - DEA is used to estimate efficiency with traditional inputs such as school infrastructure, capital, labor and municipal wealth. As output, the Portuguese and mathematics grades in the 9th grade, in the Saeb 2019 test, are considered, multiplied by the students enrolled in this year of education; as well as the inverse of per capita expenditure on elementary education.

Results and Discussion: It was concluded that most of the benchmarkings are represented by municipalities with smaller inhabitants, indicating that the population increase in municipalities increases the demand for education.
Research Implications: Thus, based on technical efficiency analyses, public policies can be proposed that mitigate the deficiencies presented in elementary education.

Originality/Value: This study contributes to the literature by estimating the efficiency of municipalities in terms of public spending on education and the efficiency results are the grades of public school students. The research introduces a new output to measure efficiency, and points to new evidence for public educational policies.
Sustainability Aspects of Carapa Guianensis Aubl Oil for Antiinflammatory Uses
Authors: Barbosa Júnior Raimundo Nonato da Silva , Andrade Eloisa Helena de Aguiar , Silva José Rogério de Araújo , Gonçalves José Francisco de Carvalho , Santos Alberdan Silva 
Published: August 2024

Objective: The objective of this study is to describe the lipidomic profile of andiroba oil and its socio-economic characteristics focused on the activities of limonoids as an alternative for the generation of nonsteroidal anti- inflammatory drugs in order to relate the generation of products that act on circular and external peripheral inflammation.

Theoretical Reference: In this context, andiroba oil (C. guianensis) has a wealth of lipid substances with chemical and socio-economic potential, highlighting its importance for local populations and its potential for sustainable bioeconomics, as this species contains nonsteroidal antiinflammatory drugs from Amazonian oil plants.

Method: The methodology adopted includes describing the lipidomic profile of andiroba oil analyzed by GC/MS, using a Zebrom 5HT capillary column specifically designed to analyze both the methyl esters of the various fatty acids and the limonoids and steroids. The bibliographic search was carried out in the CAPES periodicals on the Scopus database, using specific keywords such as andiroba, Carapa, limonoids and antiinflammatories. Three samples of andiroba oil collected in different states were used to compare the lipidomic profiles.

Results and Discussion: The results obtained revealed the presence of limonoids 7-desacetyl-7-oxogedunin, 7- oxogedunin, deacetyl gedunin; steroids campesterol, stigmasterol, b-sitosterol and various medium and long chain fatty acids. These results showed valuable information about the presence of limonoids, which have anti-inflammatory properties related to the chemical composition, which can vary with the season, the place of collection and the differences in the extraction processes of this oil. However, there is no total absence of limonoids.

Research Implications: This research's practical and theoretical implications emphasize that the active anti-inflammatory principles are found in the unsaponifiable fraction, and therefore, only lipidomic techniques can access these metabolites with more excellent resolution. Thus, with the structural identifications, in silico studies can be carried out to classify their effects on cyclooxygenase enzymes (COXs), specifically COX-1, in circular and external peripheral inflammation.

Originality/Value: This study contributes to the literature through the perspective of developing safe anti- inflammatory agents produced from andiroba oil, which is a source of great interest for topical use. This oil stands out as one of the most scientifically studied natural products, being biocompatible and presenting itself as an economical and safe alternative for treating circular and external peripheral inflammations. The relevance and value of this research is evidenced by the fact that limonoids are inhibitors of cyclooxygenases, highlighting the prospect of a new socio-economic aspect.

Published: August 2024

Objective: The objective of this study aims to reflect on an organized set of synergies that contribute to an effective artistic-environmental dialogue: the aim of this interdisciplinary dialogue is to promote a balanced, conscious and informed plan of environmental education, mediated by art. In this specific case, the promotion of artistic and cultural events becomes a subsidiary of agents' ecological awareness and consequently acts as a force capable of mobilizing and raising awareness among current and future generations of the central causes and issues of contemporary society, precisely, those that relate to the “common home”.

Theoretical Framework: We have put together a tripartite theoretical framework in which ethical, aesthetic and artistic issues are related from a dialogical perspective between art and the environment and their respective impacts in terms of intervention in the community and with the community.

Method: Narrative literature review, seeking to describe or discuss the current state of the research topic and, in particular, to draw conclusions for the results and discussion of the effects and impacts of the practices resulting from this initiative that covers a significant and broad generational framework (from early childhood to old age), applying the same model and method. In this case, the MILMESA Method and the DEP Model.

Results and Discussion: The main results emerge as the conclusion of a concrete analysis of the reality observed and the theoretical matrices that underpinned the model and method used. These results are important for future reflection, in terms of what is meant by future adjustments to the results obtained in this research context.

Implications of the research: In the future, there are certain considerations that can be reflected on and improved, based on the structure and conceptual basis emanating from the reference authors (and works) that deal with the subject under debate and intergenerational reflection.

Originality/Value: This research promotes, in a unique way, a reflection on the making of technical-scientific, participatory and interdisciplinary events, which are in great demand at an educational and scientific level, in which art and art education emerge as a dialogue between areas and as an added value in the framework of the methodologies used in this type of initiative. The aim is to align research and artistic work (and related works) and, at the same time, to reflect on the practices and projects carried out in this field with scientific and training institutions in general, including institutions with more plural and diverse missions in terms of formal, non-formal and informal education.

Authors: Suficier Darbi Masson , Muzzeti Luci Regina , Santos Alexandre Aparecido dos , Silva Rosangela da , Leão Andreza Marques de Castro 
Published: August 2024

Objective: The objective of this study is, based on the notions of practice and practical sense of Bourdieu (2009, 2011b), to analyze how the daily work of four elementary school teachers and their routines unfold.

Methodological procedures: This is an empirical sociological research in which data were collected through semi-structured interviews.

Theoretical framework: For Bourdieu, habitus produces practices and presents itself as a kind of practical sense, that is, the understanding of what should be done in a given situation.

Results and discussion: The four interviewed teachers have little time and resources to expand their cultural capital. Their routines are marked by practical sense in the classroom, that is, by moments in which the teachers' performance is marked by the automatisms of action.
Benchmarking of Aerodynamic Models for Isolated Propellers Operating at Positive and Negative Thrust
Authors: Goyal Jatinder , Sinnige Tomas , Avallone Francesco , Ferreira Carlos 
Published: August 2024

Operating a conventional propeller at negative thrust results in the operation of positively cambered blade sections at negative angles of attack, leading to flow separation. Consequently, accurately simulating the aerodynamics of propellers operating at negative thrust poses a greater challenge than at positive thrust. This study offers a comprehensive assessment of the aerodynamic modeling capabilities of numerical methods, spanning low to high fidelity, for computing propeller performance across both positive and negative thrust regimes. Low-fidelity methods, namely, blade-element momentum and lifting line theories, effectively predict propeller performance trends at positive thrust. However, they fail to capture trends at negative thrust beyond the maximum power output point due to the neglect of three-dimensional flow effects. Both steady and unsteady Reynolds-averaged Navier–Stokes (RANS) simulations with [Formula: see text] perform well across both positive and negative thrust conditions, with errors below 2% for both thrust and power magnitudes near the maximum power output point. Lattice-Boltzmann very-large-eddy simulations (LB-VLESs) with [Formula: see text] exhibit excellent agreement with experimental data with less than 1% error near the maximum power output point but with significant computational costs. Conversely, LB-VLESs with [Formula: see text] offer a more economical approach to capture general trends with the computational cost of the same order as unsteady RANS. However, wall models introduce errors in modeling flow separation, leading to a 16% overestimation of power magnitude near the maximum power output point. The results highlight the necessity of using tools with increased fidelity levels when considering propeller operation at negative thrust compared to the conventional positive thrust regime.
Influence of Time-Varying Freestream Conditions on the Dynamics of Unsteady Boundary-Layer Separation
Authors: Ambrogi Francesco , Piomelli Ugo , Rival David E. 
Published: August 2024

Unsteady flow separation of a turbulent boundary layer under dynamic pressure gradients is investigated using the Large-Eddy Simulation technique. The unsteadiness is introduced by prescribing an oscillating freestream vertical-velocity profile at the top boundary of the domain. Although previous studies, including Ambrogi et al. (Journal of Fluid Mechanics, Vol. 945, Aug. 2022, p. A10) and Ambrogi et al. (Journal of Fluid Mechanics, Vol. 972, Oct. 2023, p. A36), focused on the kinematics of the flow and the effects of the oscillation frequency on flow separation, the goal of this paper is to analyze the effects of three time-varying freestream-forcing profiles while the oscillation frequency is kept the same for all Cases. Whereas in Case A the freestream-velocity profile changes from suction–blowing to blowing–suction in a complete cycle, Cases B and C are both suction–blowing only and the strength of the adverse pressure gradient is modulated in time. Moreover, the boundary layer in Case B never approaches a zero-pressure gradient condition. A closed separation bubble is formed for all Cases; however, its dimensions change depending on the far-field forcing. The time evolution of turbulent kinetic energy (TKE) reveals an advection mechanism of turbulent structures out of the domain for all Cases. Whereas in Case A and C the high-TKE region, generated in the separated shear layer, is washed out of the domain as a rigid body, in Case B the separation bubble remains present and the advection mechanism of TKE is characterized by a breathing pattern.

Authors: Цветов П.Ю. 
Published: August 2024

В статье рассматриваются работы вьетнамских ученых, посвященные историческим личностям, деятельность которых была ознаменована реформами. В большинстве своем это были монархи, которые, укрепившись на троне, проводили преобразования в налогообложении, меняли административное деление страны. В XIX веке появились идеи сотрудничества с Западом, развития науки и техники. В последние годы особый интерес вьетнамских историков к деятельности реформаторов обусловлен политической задачей — найти в прошлом Вьетнама примеры преобразовательной деятельности, обосновывающие легитимность курса реформ, получившего название «дой мой», который Компартия Вьетнама проводит с 1986 года.
The article examines the works of Vietnamese scholars dedicated to historical figures whose activities were marked by reforms. The most of them were monarchs who after gaining the foothold on the throne carried out changes in taxation and the administrative division of the country. In the 19th century, reform proposals included the ideas of cooperation with the West or the development of science and technology. The political task of finding the examples of reform efforts in the past of Vietnam to support the legitimacy of the reforms called «Doi Moi», which is the name of the policy Communist party of Viet Nam carried out since 1986, has aroused considerable interest of Vietnamese historians in recent years.

TOURS OF THE MASTERS OF THE GERMAN DRAMA SCENE IN MOSCOW IN THE 1880–1890s
Authors: Огородникова О.А. 
Published: August 2024

Статья посвящена одному из ярких явлений в истории русско-немецких культурных связей в области драматического театра — многолетним гастролям крупнейших сценических деятелей Германии Эрнста фон Поссарта и Людвига Барная в Москве, организованным в 1880–1890-х годах антрепренером и директором Немецкого театра Г. Парадизом. Проанализированы особенности восприятия выступлений немецких артистов, познакомивших москвичей с собственной трактовкой образов классического, характерного и комического репертуара в произведениях мировой классики и пьесах современных европейских авторов. Выявлено значение гастролей для широкой зрительской аудитории, творческой интеллигенции и критиков, получивших возможность сравнивать художественный стиль и актерское мастерство разных по амплуа и сценическому предназначению представителей немецкой театральной школы. На примере известных режиссеров и артистов, являвшихся в пору своей молодости «временными учениками» немецких мастеров, рассмотрен педагогический аспект их деятельности. Показана роль блистательных гастролеров в актерско-художественном становлении представителей отечественного театра. В итоговых выводах статьи подчеркнуто значение гастрольной деятельности Э. Поссарта и Л. Барная, их вклад в развитие диалога культур России и Германии в конце XIX века.
The article is devoted to one of the brightest phenomena in Russian-German cultural relations in the field of drama theater, namely to the long-term Moscow tour of the largest representatives of the German stage, Ernst von Possart and Ludwig Barnay, which served as an opportunity to introduce the audience to their own interpretation of the images of the classical, characteristic and comic repertoire in the works of world classics and plays by modern European authors. The analysis is presented of the perception of these performances by the general public, art criticism and the theater community, who had the opportunity to compare the artistic style and acting skills of the masters of the German stage.
