Abstract
The ternary Laves phases Sr2Pd3Sn, Eu2Pd3Sn and Eu2Pd3In were synthesized by induction melting of the elements in sealed tantalum ampoules. The polycrystalline products were characterized through their powder X-ray diffraction patterns. The structure of Eu2Pd3Sn was refined from single crystal X-ray diffractometer data: Mg2MnGa3 type, Cmcm, a = 583.36(5), b = 908.31(7), c = 958.06(8) pm, wR2 = 0.0366, 557 F
2 values, 23 variables. The palladium and tin atoms show the inverse coloring on the network of condensed tetrahedra of Mg2MnGa3, i.e., MnGa3 versus Pd3Sn. Refinement of the occupancy parameters revealed small defects for the europium site, leading to composition Eu1.962(6)Pd3Sn for the studied crystal. Sr2Pd3Sn is a Pauli paramagnet and Eu2Pd3Sn shows Curie-Weiss paramagnetism (7.86(1) µB Eu atom−1 and Θ
P = 48.1(1) K). Ferromagnetic ordering is observed below T
C = 46.1(1) K. The 119Sn and 151Eu Mössbauer spectra of Sr2Pd3Sn and Eu2Pd3Sn are discussed with respect to electron density changes as a function of the tin content and the ionicity in the sequence of the stannides Sr2Pd3Sn/Eu2Pd3Sn → Sr2Pd2Sn/Eu2Pd2Sn → EuPdSn → EuPdSn2.
Understanding formation of the InPd3polymorphs: a DFT study
Authors: Roy Nilanjan 
Published: April 2023

AbstractThe intriguing experimental results regarding the synthesis and structure types adopted by binary InPd3have been fundamentally addressed using first-principles density functional theory calculations. Longer annealing time at higher temperature leads to stronger and more optimized heteroatomic In–Pd contacts that result in the extended ordering between them and leading to the ZrAl3structure type. This is followed by another ordered derivative of the TiAl3-type and the metastable disordered AuCu-type when the annealing time and temperature were reduced. The thermodynamic stability order of these three polymorphs of InPd3, i.e. ZrAl3-type > TiAl3-type > AuCu-type is understood from the correlation between formation enthalpies, Madelung energies, and electronic structure and chemical bonding analysis.

Authors: Menezes Thereza Cristina Cardoso 
Published: April 2023

O artigo propõe uma reconstituição no tempo das políticas de regularização fundiária no Brasil, enfatizando o conjunto de importantes transformações normativas e procedimentos administrativos observados ao longo de pouco mais de uma década. Aponta-se para um intenso esforço para a promoção da regularização fundiária que combinou os mais variados interesses, atores e matizes ideológicos para regularizar o vasto estoque de terras amazônicas. O ambiente favorável a formalização do mercado de terras e tolerante com ilegalidades encoraja o desmatamento, incentiva a expansão de apossamentos ilegais e promove um ambiente de insegurança e violência contra as comunidades tradicionais da Amazonia.

Published: April 2023

O presente artigo trata de um relato autobiográfico acerca das práticas de cuidado e da poética do encontro de cinco gestalt-terapeutas de diferentes regiões do Brasil que formaram um grupo para compartilhar entre si suas angústias e dialogar por meio da arte e do apoio mútuo no contexto pandêmico da covid-19. Os encontros iniciaram em 2021 e seguem até osdias atuais com propostas artísticas em interlocução com a Gestalt-terapia e o pensamento ético-político que nos atravessa em sociedade. Para isto, utilizam a metodologia autobiográfica, apresentando obras construídas em grupo, fotografias e registros de diários pessoais no intuito de refletir sobre a importância do coletivo e do compartilhamento de histórias como espaço deresistência e afetação. Considera-se resultados das interlocuções que o compartilhamento de histórias e da arte entre gestalt-terapeutas,configura a poética da clínica gestáltica em ato, contribuindo para construção de rede de apoio entre psicoterapeutas e que reverbera no cuidado coletivo. Consideramos assim fundamental, na contramão de um pensamento neoliberal individualizante, discutirmos a importância dos grupos e coletivos na constituição de uma proposta comunitária de cuidado, autonomia e atenção em saúde.Palavras Chave: Gestalt-terapia.

Phosphate organomineral fertilizer based on banana peels and coffee ground waste
Authors: Teixeira Gustavo Fernandes , Santos Kássia Graciele dos 
Published: April 2023

Population growth impacts all areas of society. Food production is one of the most pressing challenges resulting from population growth creating the need for optimized production and the application of innovative ideas in the agricultural sector to meet growing demands. A common method used to increase crop yields is the application of fertilizers. Aiming to reduce the impact of fertilizer application, specifically soil leaching, this study proposes the production of a slow-release organomineral fertilizer made from triple superphosphate. The proposed fertilizer was created via hand extrusion ensuring heterogeneity in the resulting fertilizer pellets. The sample F15 (9,2% of banana peel; 1,6% of starch; 57,3% of TSP and 32% of coffee waste) showed the slow-release time (1h for the release of 50% of the nutrients and 8h for the total release). Tests were then conducted seeking to analyze and improve their pyrolysis performance, biochar creation potential, and polymer coating in the soil. Test results enabled improvements to the fertilizer pellets via polymeric coating and thermal treatment. Both methods displayed good results, however, the thermal treatment method resulted in fertilizer loss due to unwanted reactions. Test results were analyzed using Weibull's kinetic model, which after great consideration, was deemed the most appropriate to analyze the properties of the proposed fertilizer. The development of pelleted and heat-treated organomineral fertilizers is promising because, in addition to saving the mineral fraction, it also provides an environmental benefit by reusing waste that would otherwise be thrown.

a.	In a world facing global crisis after crisis, a new approach to urban development is emerging. This book is the result of a three years of iterative Research which explores the ways in which technology, community, and urban design can work together to create more sustainable and productive cities. The book offers insights into how enabling technologies and citizen empowerment are leading to new economic models and a collaborative culture. Through an in-depth analysis of the city of Rome, the Research demonstrates how a focus on community building and new urban models can lead to more sustainable, resilient, and productive cities. The outcome of the Research is a hyper-local tool that enables bottom-up initiatives to respond to specific needs and help develop new economies. This approach, combined with top-down initiatives from Administrations, could be useful for further creation of proposals that precisely address community needs. Findings of the Research would be useful for policymakers, urban planners, makers, designers, and citizens who want to design and advocate for sustainable urban development models and thriving neighborhoods. With its practical insights and real-world examples, this book offers a roadmap for building more resilient and sustainable cities in the 21st century.
AXOIDS OF HOOKE’S JOINT
Authors: Koriak Oleksandr 
Published: April 2023

The analysis of literary sources devoted to the research and construction of cardan transmissions using the Hooke's joint showed that the peculiarities of the spherical movement of the cardan joint crosspiece are insufficiently covered. This is explained by the relatively small weight of the crosspiece, due to which it almost does not affect the dynamics of the cardan transmission. The need to take into account the mass-geometric parameters of the crosspiece and to analyze comprehensively its movement may arise during accurate calculations of high-speed cardan transmissions. In this case, it is convenient to consider the movement of the crosspiece as rolling without sliding of the moving axoid on the stationary axoid. This approach makes it possible to more fully investigate the peculiarities of the spherical movement of the crosspiece and gives a visual representation of the orientation of its instantaneous axis of rotation in fixed and moving coordinate systems. Based on this, this work is devoted to the construction of a kinematic model of the Hooke's joint crosspiece, the movement of which is considered as rolling without sliding of a moving axoid on a stationary one.
As a result of the kinematic analysis of the Hooke's joint, the equations of the hodographs of the vector of the absolute angular velocity of the crosspiece in the fixed and moving coordinate systems were obtained, and the parameters of the fixed and moving axoids of the crosspiece of the cardan joint were determined. It is proved that the stationary axoid of the crosspiece of the Hooke's joint is an oblique elliptic cone with the apex in the center of the crosspiece, and its opposite generatrices, crossing the major axis of the guide ellipse, coincide with the axes of the drive and driven shafts of the joint. The moving axoid of the crosspiece is a closed conical surface with a variable opening angle, the maximum value of which is equal to twice the value of the interaxial transmission angle. With small values of the interaxial angle, which occur in the practice of using a single Hooke’s joint, a moving axoid can be approximately considered as a straight circular cone with a vertex in the center of the crosspiece and an opening angle equal to twice the value of the interaxial transmission angle. The error of this assumption increases rapidly with the increase of the interaxial transmission angle. The correctness of the obtained mathematical model was confirmed by computer modeling in the Autodesk Inventor environment.
The obtained results can be used in the study of dynamic processes that occur in cardan transmissions using Hooke's joint.
NEW INFORMATION OPERATORS IN PROBLEMS OF NUMERICAL INTEGRATION OF FUNCTIONS OF THREE VARIABLES
Authors: Nechuiviter Olesia , Ivanov Serhiy , Kovalchuk Kyrylo 
Published: April 2023

The rapid development and implementation of the latest information technologies in many fields of science and technology contribute to the rise of new methods in mathematical modeling of systems and processes. In particular, new mathematical theories have appeared that can be effectively used for building and improvement of existing mathematical models of various phenomena and objects. One of these theories is the theory of new information operators, authored by the Laureate of the State Prize of Ukraine in Science and Technology, doctor of physical and mathematical sciences, professor (думаю, это излишняя информация в аннотации) O. M. Lytvyn. New information operators have found their application in the digital processing of signals and images, namely in the numerical integration of rapidly oscillating functions of many variables. Cubature formulas were built that are optimal in the order of accuracy and use the value of the non-oscillating factor of the integrand function not only at points, but also on planes or lines. The article demonstrates the application of new information operators to the numerical integration of functions of many variables, namely, the issue of approximate calculation of the integral from functions of three variables is considered in the case when the information about the function is given by its traces on the lines. The cubature formula uses an interlineation operator built on the basis of an interflatation operator with auxiliary functions in the form of piecewise constant splines. An estimate of the approximation error of the proposed cubature formula on the class of differentiable functions was obtained. The results of the calculation experiment in the computer mathematics system Mathcad are presented. Numerical calculations confirm the theoretical statements of the study.
ELASTIC TRANSVERSAL-ISOTROPIC SPACE WITH TWO UNIAXIAL PARALLEL CIRCULAR CRACKS AND ASSOCIATED PROBLEMS OF BASICITY
Authors: Nikolaev Oleksii , Krainychenko Alina 
Published: April 2023

In the paper a problem of the stress state in a transversely isotropic space with two parallel circular cracks, the centers of which are located on the axis of anisotropy of the space, is investigated. A constant normal load acts on the crack planes. The problem is solved by the generalized Fourier method. For this purpose, systems of compressed spheroidal coordinates are introduced, the origins of which are connected to the centers of cracks. The general solution of the problem is constructed in the form of series based on axisymmetric variants of the general vector solutions of the system of equations of equilibrium of a transversely isotropic body in spheroidal coordinates, which were previously constructed by one of the authors of the paper. To implement the method, it is further generalized to compressed spheroidal coordinate systems with origins shifted along the axis. For this purpose, new addition theorems for basic vector displacements of transversally isotropic bodies in the above-mentioned coordinate systems are obtained. After applying the generalized Fourier method, the problem is reduced to an infinite system of linear algebraic equations. It is proved that under certain geometrical and mechanical conditions the operator of the system is a Fredholm operator. The reduction method is used for the numerical solution of the system. Graphs of normal stresses in the plane of one of the cracks outside its boundaries, as well as values of stress intensity factor at the top of the crack for different geometric parameters of the cracks, are obtained. The obtained results agree with the known value of the stress intensity factor in the problem with one crack. The practical convergence of the reduction method is studied.
As an important related problem, the problem of proving the basicity of a general axisymmetric set of external solutions of the system of equilibrium equations of a transversally isotropic body whose boundary is described in compressed spheroidal coordinates is considered. The key problem here is obtaining subtle estimates from below of the modulus of the determinant of the first boundary value problem. As a corollary of the obtained result, several important estimates from the theory of special functions are derived, in which Legendre functions of the second kind from a purely imaginary argument appear.
Posibilités et défis de la clase inverse pour l'enseignement du français langue étrangère

Published: April 2023

La classe inversée (« flipped classroom ») est une approche pédagogique consistant à « inverser » et à adapter les activités d’apprentissage traditionelles aux étudiants en utilisant la formation à distance et la formation en classe, et elle favorise la co-construction ou co-élaboration des apprentissages entre pairs et s’appuie sur l’apprentissage individuelle grâce aux Technologies de l’information et de la communication pour l’enseignement (TICE). Cette approche se prête particulièrement à l’enseignement/apprentissage des langues étrangères car elle offre aux élèves davantage d’occasions d’être exposés à la langue cible, à l’intérieur et à l’extérieur de la salle de classe, grâce aux nouvelles technologies. Pourtant très peu d’études sur la classe inversée se concentrent sur l’enseignement/apprentissage des langues. Cet article traite du concept de la classe inversée, en tenant compte de ses principaux fondements théoriques. Il analyse ensuite ses possibilités et ses défis dans le domaine de l'enseignement du français langue étrangère.

El aula invertida o flipped classroom es un enfoque pedagógico que consiste en “invertir” y adaptar las actividades de aprendizaje tradicionales al alumnado utilizando las ventajas de la educación a distancia y de la formación en el aula, fomentando la construcción y el desarrollo del aprendizaje de manera conjunta y entre iguales, y favoreciendo el aprendizaje individual a través de las Tecnologías del Aprendizaje y el Conocimiento (TAC). Este enfoque es especialmente interesante para los procesos de enseñanza-aprendizaje de lenguas extranjeras, pues ofrece al alumnado más oportunidades de estar en contacto con el idioma objetivo, tanto dentro como fuera del aula, mediante el uso de las nuevas tecnologías. Sin embargo, son limitados los estudios sobre el aula invertida que se centran en la enseñanza-aprendizaje de idiomas. Este artículo discute el concepto de aula invertida, teniendo en cuenta sus principales fundamentos teóricos, para posteriormente analizar sus posibilidades y principales en el ámbito de la enseñanza del francés como lengua extranjera.
