Published: May 2024

Background and Objectives: Child sexual abuse (CSA) is a critical global issue that significantly impacts children's physical and psychological health. Parents and teachers play vital roles in preventing and addressing CSA. This study aims to assess the knowledge levels of parents and teachers regarding sexual offenses among school children in the Sheopur district, identifying gaps to inform future educational and training programs. Methods: A cross-sectional survey design was employed, involving 200 participants from various clusters within the Sheopur district. A structured questionnaire assessed demographic variables and knowledge of CSA. Results: The study revealed that 67% of teachers had poor knowledge of CSA, with none exhibiting good knowledge, whereas 71% of parents had average knowledge and 11% had good knowledge. Demographic analysis indicated differences in awareness levels, influenced by age, gender, education, and occupation. Teachers, despite higher educational qualifications, demonstrated inadequate CSA awareness, highlighting a need for specialized training. Conclusion: Significant knowledge gaps exist among parents and teachers regarding CSA, with teachers particularly lacking adequate understanding. These findings underscore the necessity for comprehensive, targeted educational programs and training initiatives to enhance CSA awareness and prevention. Effective implementation of the Protection of Children from Sexual Offenses (POCSO) Act, 2012, through practical training and ongoing assessment, is crucial to safeguard children's well-being and rights.

MODIFICATION OF THE LEMAITRE DAMAGE MODEL BY A LOCAL MULTIAXIAL STRESS STATE FUNCTION
Authors:   Federal Research Center “Kazan Scientific Center of the Russian Academy of Sciences”, Tumanov A.V.
Published: May 2024

A modification of the Lemaitre damage model is proposed based on the introduction of a function sensitive to the Lode parameter. The modified model is imported into the ANSYS software as a dynamically linked custom tag library. The model takes into account isotropic hardening based on the exponential Voice model and kinematic hardening based on the Armstrong–Frederick model. Limit state curves are obtained by numerical finite element analysis for three types of experimental cylindrical specimens: a compression specimen under additional external pressure, a circular-notch specimen under uniaxial tension, and a hollow cylindrical specimen under combined tension, torsion, and internal pressure. The advantages and disadvantages of the proposed model are considered. Recommendations are given for choosing model parameters to predict limit states under multiaxial loading.

The origins and formation mechanisms of neotectonic structures in a part of the Mongolian-Siberian region were identified by geodynamic zoning based on multidimensional statistical analysis of numerical arrays describing geological-geophysical and geological-geomorphological processes. These processes in the regional lithosphere were described by a set of 11 geological and geophysical parameters, divided into three main groups using the hierarchical method of cluster analysis. The first group includes the seismic moment, the density of active faults, the rates of current horizontal deformations, and the magnitude of the deep heat flow. The second group involves the thicknesses of the earth’s crust and exogenous active layer, the velocities of current horizontal movements, and the amplitudes of vertical neotectonic movements. The third group includes gravity anomalies and the lithosphere thickness. The spatial grouping of parameters by cluster analysis (K-means method) yields seven clusters, whose spatial position and composition are determined by the geological history, geological structure, geodynamic evolution of the region, and the current deformation rates. Some clusters characterize large rigid lithospheric blocks, while other clusters describe large active fault systems in the given area. The search for latent factors that make the greatest contribution to the dispersion of the geological and geophysical parameter values was carried out using the principal component method, which makes it possible to minimize the number of factors. Four main factors were identified for areas that differ in the morphology and origin of neotectonic structures: (i) higher horizontal compressive and tensile strains, (ii) dynamic effect of mantle anomalies, manifested in uplifts and arching, (iii) activation of thinned lithosphere within the boundaries of lithospheric plates and large blocks, and (iv) active shear deformation of the earth’s crust. The results of clustering and factor analysis of numerical arrays describing the geological-geophysical and geological-geomorphological processes within the Mongolian-Siberian region can be interpreted in the framework of physical mesomechanics.
EFFECT OF PRESSURE ON ELASTIC CONSTANTS AND RELATED PROPERTIES OF RARE-EARTH INTERMETALLIC COMPOUND TBNIAL

Published: May 2024

The Lennard-Jones potential approach is used to investigate the effect of pressure on the ultrasonic and elastic properties of the rare-earth ternary TbNiAl intermetallic compound. The second- and third-order elastic constants of TbNiAl are considered using the potential model. The pressure-dependent higher-order elastic constants are studied, and it is observed that the elastic constants of the TbNiAl compound increased monotonously with pressure. The hexagonal TbNiAl compound is mechanically stable up to the pressure 20 GPa according to the Born elastic stability criteria. The Voigt-Reuss-Hill approach is used to compute such elastic parameters as Young’s modulus, bulk modulus, Poisson’s ratio, and shear modulus in the pressure range 0-45 GPa. Hardness, melting temperature, and anisotropy are also determined for the intermetallic TbNiAl compound. The pressure-dependent velocities and attenuation of ultrasonic waves in this ternary compound are evaluated. The computation results are also satisfactory in estimating the Debye temperature and thermal conductivity Kmin under different pressure. It is observed that TbNiAl has a significant anisotropy at zero pressure, which becomes stronger as the pressure increased. This ternary compound behaves as its purest form at higher pressure and is more ductile, which is demonstrated by the minimum attenuation.
SPONTANEOUS STABILIZATION AND LARGE-SCALE OSCILLATIONS OF AN ACTIVE MEDIUM WITH NEGATIVE DISSIPATION
Authors:   Galkin Donetsk Institute for Physics and Engineering, FILIPPOV A.E. , POPOV V.L. ,   Technische Universität Berlin
Published: May 2024

A numerical model of an “active medium” is considered which invokes linear elasticity and a negative seed dissipative constant dynamically renormalized under deformation. It is shown that despite the expected instability of such a system, it spontaneously exhibits stable dynamic behavior in a wide range of geometric configurations and initial causes of deformations. In the stable dynamic modes, dissipation that changes its sign in time and space forms complex quasi-periodically repeating patterns and the entire volume (length, area) of the system undergoes large-scale oscillations. In addition to academic interest, the results obtained can be applied to mechanical and biological studies.

This paper presents the numerical and experimental results of hardening an annular zone on the flat surface of a X20Cr13 steel sample by friction stir processing (FSP) with a WC-Co hard alloy tool moving along circular and fan-shaped paths. A finite element model of the process is proposed for predicting the temperature distribution through the width and depth of the annular zone for the considered tool paths and for detecting the reverse tempering regions. The influence of the paths of a cylindrical friction stir tool with a flat end on microhardness distribution in the surface layer of the hardened zone was studied experimentally. It was shown that FSP along a fan-shaped path provides uniform hardening of the annular zone, while processing along a circular trajectory leads to softening of the material in the regions where the friction tracks overlap. The uniformity of surface hardness in the FSP-hardened annular zone of X20Cr13 steel was evaluated by calculating the CU index proposed by Campana. The hardening behavior is in full agreement with the results of finite element simulation of the FSP process. Hardness measurements and microstructural studies showed that the fan-shaped tool path provides surface layer hardening to a depth of up to 400 μm with a CU index ranging from 0.78 to 1.00. In the case of a circular path, the CU index ranges from 0.48 to 0.72 at the same depth. XRD analysis of the hardened layer revealed pronounced peaks corresponding to the (110)α, (200)α and (211)α lines, indicating the formation of martensite with different tetragonality at the given depth. The proposed research methods can be applied to evaluate the FSP efficiency when using other workpiece and tool materials.

This study examines the influence of the mechanical processing of a titanium nitride based powder mixture on the change in the morphology of the CO2 laser treated surface, the weld pool morphology, and its cross-sectional structure. Ultrafine titanium nitride particles used as nanomodifier, which have low wettability in the metal melt and are not entrained by its convective flows, accumulate in the subsurface and reduce the structural modification efficiency in the bulk of the treated material. Processing of the modifying Ti + TiN mixture for 9 min leads to the formation of composite particles (5-7 pm) in which ultrafine titanium nitride particles are uniformly distributed over the surface and volume. The composite particles melt during laser irradiation and form ultrafine titanium nitride particles of nanomodifier cladded with a thin titanium layer, which have a smaller contact angle. As a result, the particles are more evenly distributed over the weld pool and the number of crystallization centers increases, leading to the formation of a fine homogeneous structure of the material. The microhardness increases by 32%, and its standard deviation decreases by a factor of 1.5 3.0.

The paper presents experimental studies on the synthesis of a titanium matrix composite based on Ti64 titanium alloy and TiB2 ceramic particles by laser surface cladding. The weight percentage of TiB2 ceramics in the composite was 5, 10, and 15%. The phase composition of the resulting materials was analyzed by standard X-ray diffraction and synchrotron X-ray diffraction. It was found that the structure of the titanium matrix composite with 5 wt % ceramics consists of TiB nanowhiskers, and that of samples with higher ceramics content exhibits TiB whiskers with a width of several micrometers. The addition of TiB2 ceramics leads to an increase in Young’s modulus and nano-/microhardness of composite samples compared to Ti64 alloy. The indentation method was used to study the formation of a phase that does not correspond to TiB2 ceramics and microscale TiB whiskers and has elastic properties exceeding the elastic properties of the original Ti64 matrix phase. Analytical predictions showed an increase in the effective elastic properties of the formed heterogeneous material with the predicted new phase. It was also found that a lower friction coefficient can be achieved by forming a structure with nanowhiskers, while higher Young’s modulus and microhardness can be obtained by forming a structure with microwhiskers.
METHODS OF ACCOUNTING FOR TEMPERATURE AND STRAIN RATE VARIATION IN MULTILEVEL CONSTITUTIVE MODELS OF METAL DEFORMATION (ANALYTICAL REVIEW)

Published: May 2024

Technological metal forming processes involving hot and superplastic deformation are sensitive to temperature and strain rate. This is because inelasticity mechanisms operate in different ways under different conditions, leading to the formation of different structures and therefore different effective physical and mechanical properties of the material. Optimal temperature and strain rate conditions for the forming process which provide improved performance characteristics of the resulting products with acceptable energy consumption (or, conversely, minimum energy consumption with acceptable performance characteristics) can be most effectively determined by mathematical modeling. The key elements of the latter are constitutive models for describing the behavior of the material (physical equations), which can account for the influence of temperature and strain rate on various mechanisms of inelastic deformation. Such constitutive models can be most effectively developed using a multilevel approach based on the introduction of internal variables, crystal plasticity, and an explicit description of the material structure and physical deformation mechanisms. There are many works that propose multilevel mathematical models of metals that somehow explicitly account for the temperature and strain rate effects on inelastic deformation. Based on physical considerations, this analytical review defines the most promising approach to constructing multilevel constitutive models with comprehensive consideration of the temperature and strain rate effects.

The effect of aging temperature in the range of 300-500°C on the structure, R martensitic transformations and mechanical characteristics of nanocrystalline Ti-50.9 at % Ni alloy with a grain/subgrain structure was studied. It was found that variation in the spatial distribution of coherent Ti3Ni4 particles in the nanostructure from their location on dislocations during low-temperature aging to precipitation at dislocation boundaries under intense aging is accompanied by a change in the morphology of the R phase from a nanodomain to a self-accommodating lamellar structure. The nanodomain structure of the R phase contributes to uniform deformation of the alloy during loading/unloading and stabilization of superelasticity. When loading the alloy with a lamellar R-phase morphology, localized deformation bands are formed by the R-phase reorientation in a Luders deformation manner.
FORMATION OF THE NEAR-FAULT DAMAGE ZONE DURING DYNAMIC RUPTURE IN A CRYSTALLINE ROCK MASS
Authors:   Sadovsky Institute for Dynamics of Geospheres RAS, BUDKOV A.M. , KOCHARYAN G.G.
Published: May 2024

Many models for analyzing the dynamic propagation of seismogenic ruptures are based on solving classical problems of fracture mechanics. It is assumed that the fault is a shear fracture mode with uniformly distributed friction and stresses at the crack tip. Known fracture mechanics theories do not describe the formation of laterally oriented damage zones, i.e., in the direction perpendicular to the crack plane. Observational data indicate the presence of a fairly extensive zone of damaged material in the vicinity of the fault. This is the zone of dynamic influence where the material has an increased number of fractures, higher permeability and lower elastic wave velocities. A correct assessment of the properties and sizes of zones of dynamic influence is crucial for constructing adequate earthquake preparation models. This paper analyzes the development patterns and quantitative characteristics of the damage zone during dynamic earthquake rupture and quasi-static evolution of the fault. To estimate the size and mechanical characteristics of the near-fault damage zone caused by movement along the slip surface, it is convenient to use the value of the second invariant of the deviatoric stress tensor (shear intensity). Matching of the calculated value with one or another degree of rock mass damage can be done using measurement data from large-scale explosions, by comparing them with the calculation results. It is shown that coseismic movement along the fault leads to insignificant changes in the properties of the host rock mass. Although the longitudinal wave velocity near the fault decreases markedly by 30-35%, the permeability increases only by approximately a factor of three, and the increase in the degree of fracturing is almost unnoticeable. This means that the properties of the rock mass change due to the opening of preexisting cracks. Repeated movements do not radically change the characteristic dimensions and properties of the damage zone. It is concluded that the fault-affected zone is formed mainly at the quasi-static stage of the formation of a single main fault zone through the coalescence of individual macrofractures, and future seismogenic movements add to the already existing amount of fractures.

Statistical data analysis was performed based on the results of standard tests with metallic materials. The relationship was found between the so-called fatigue limit, which is considered as the transition boundary between microand mesoscale fatigue fracture processes, and mechanical characteristics under monotonic tension. Using heat-resistant alloy EI698 and titanium alloy VT22 as examples, it was shown that the mechanisms of fatigue crack initiation and growth in materials with different ratios of fatigue strength to yield strength are different. The mechanism of slip band formation determines the fatigue crack initiation and its early growth stage for materials with a σ-1/σ0.2 ratio close to 1 and higher, as was shown for EI698. For materials with a σ-1/σ0.2 ratio below 1, the fatigue crack initiation is associated with mechanisms other than slipping, as demonstrated for VT22.

Using regression analysis through a component-wise search for regressors, a computational approach is proposed for estimating the oriented curvature of vortex-like atomic structures. The studied discrete vector fields of atomic displacements of such structural states are obtained based on the results of molecular dynamics simulations of a deformable defect-free crystallite. Within the given approach, a continuous representation of the desired discrete vector field is obtained. The redistribution of the free volume and reorientation of the crystal lattice are analyzed. It is found that the value of oriented curvature outside specific regions (vortex centers and regions of compensation of atomic displacements) is about |K| ≈ 0.286 nm-1. The relationship is shown between vortex-like structures and model concepts of a continuous disclination-type defect.

A cultura indígena ainda é uma grande incógnita e esta envolta de misticismo e magia que leva a pensar como se dá esse processo de transformação da matéria prima para o produto final. Entender as culturas macuxi e wapichana é vislumbrar um universo cheio de conhecimentos e saberes tradicionais riquíssimos que por muitos foram considerados apenas como conhecimento do senso comum e não como conhecimento científico. Essas tradições milenares atualmente adentram em um espaço maior da sociedade, demonstrando sua importância, sua identidade e o respeito pela mãe terra, que fornece ao ser humano uma gama de material para ser trabalhado e partir dele prover objetos com característica e especificidades próprias das culturas. Como objetivo geral desta pesquisa foi identificar o que é considerado cultura e arte dos povos macuxi e wapixana, e as comidas e bebidas cultivadas por gerações, entre outras artes praticadas por eles. Assim entender como as características de cada cultura, sua identidade e o como de produção dos artesanatos, adornos, dança etc. é entender que a cultura não é estável e nem que se extingue em si, mas que é necessário tomar proporções interculturais, nacionais e internacionais de modo a se fazer conhecer e expandir valores, crenças e saberes tão ricos de significados e de conhecimentos que são milenares.

Apple pomace, a byproduct from juice industry, can be used as a valuable nutraceutical, hence its phenolic compounds, including rutin, are powerful antioxidants. This work evidence the extract enriched with apple polyphenols from apple pomace using ethanol: water as solvent and partitioned with ethyl acetate (1:1 w/w), where its lyophilized product was evaluated for its photochemopreventive action on MRC-5 fibroblasts against a harmful UVA radiation dose. The enriched apple pomace extract was able to promote photochemopreventive action against UVA radiation, decreasing cell death and the lipid peroxidation formation. Therefore, the optimized extraction process may make the apple pomace application viable as a source of bioactive extracts with photochemopreventive action against ultraviolet radiation to the use in dermal formulations.

A hepatite A continua sendo um desafio persistente na região norte do Brasil, especialmente na extensa área da Ilha do Marajó. Esta região desempenha um papel de relevância na economia estadual, sendo caracterizada, contudo, por desafios socioeconômicos significativos, marcados por um baixo índice de desenvolvimento humano e pela carência de infraestrutura básica. Consequentemente, esta pesquisa almeja avaliar o impacto de medidas de vacinação na diminuição da prevalência da referida enfermidade na Ilha do Marajó. Adicionalmente, o estudo concentra-se na realização de um mapeamento e análise de notificações de casos de hepatite A no período compreendido entre 2010 e 2020, por meio de um estudo ecológico, descritivo com a análise secundária de dados epidemiológicos coletados entre 2010 e 2020, obtidos por meio de consulta fornecida pelo sistema TABNET, disponibilizados pelo Departamento de Informática do Sistema Único de Saúde (DATASUS). Como resultados, a predominância em homens, principalmente na faixa pediátrica, aponta para comportamentos de menor higiene pessoal e interação frequente com ambientes contaminados. A análise por faixa etária revela que a sintomatologia moderada ou assintomática em crianças de 5 a 9 anos contribui para a transmissão em agrupamentos escolares e consequentemente entre familiares. Além disso, a correlação significativa entre baixa escolaridade e maior incidência destaca lacunas na informação sobre a doença e práticas preventivas. A fonte de infecção mais associada é alimentos/água contaminados, alinhando-se com a natureza fecal-oral da transmissão do vírus da hepatite A. Isso sublinha a importância crítica do saneamento básico na região, ressaltando a necessidade de melhorias nesse aspecto. O cenário na região Marajoara é complexo, com desafios logísticos, condições climáticas e acesso restrito aos serviços de saúde contribuindo para as persistentes taxas elevadas de hepatite A. A análise destaca a necessidade urgente de medidas preventivas adaptadas às particularidades geográficas, climáticas e de acesso aos cuidados de saúde da região.

Os Núcleos de Inovação Tecnológica (NITs) são órgãos que tem como responsabilidade gerenciar a inovação. O presente artigo tem como objetivo analisar a divulgação das informações sobre as Propriedades Intelectuais (PI) desenvolvidas pelos Núcleos de Inovação Tecnológica (NITs) das Instituições de Ensino Superior (IES) Públicas do Estado da Bahia. A pesquisa foi realizada em três etapas, sendo a primeira um estudo bibliográfico, a segunda uma análise documental dos registros de Propriedade Intelectual no INPI dos NITs, e a terceira a análise dos dados coletados. Os resultados mostraram uma discrepância na quantidade de produções registradas no INPI pelos NITs, mesmo em instituições que possuem tempo similar de funcionamento. A pesquisa destaca a importância dos Núcleos para o fomento e desenvolvimento tecnológico da região e da sociedade, mas ressalta a necessidade de um plano de comunicação para divulgar e apresentar as informações produzidas pelos NITs à sociedade. Como resultados, este estudo abre precedente para novas pesquisas sobre o tema, a fim de compreender os desafios e obstáculos que possam dificultar a maior produção nos NITs da Bahia e a divulgação dos dados produzidos pelas respectivas áreas.

Authors: Luís Francisco José Silva do Amaral , Anjos Neto João Dantas dos , Freitas Marcos Costa de
Published: May 2024

O artigo investiga a performatividade do corpo, considerando-o como abordagem para compreender as táticas de interações humanas nas fronteiras da cultura, geografia e gênero, em um estudo investigativo no contexto de travestis migrantes brasileiras. Enfocam-se as performatividades e os métodos de comunicação dessas trabalhadoras, questionando a negociação da subalternização transgressiva e social. Indaga-se a relação entre produção discursiva e comportamental, comparando a produção simbólica do corpo estrangeiro e ilegal em um contexto geo migratório, com a produção estrutural do corpo percebido como fora da ordem dos trabalhadores migrantes brasileiros. Debatem-se as maneiras pelas quais os trabalhadores migrantes produzem diferenças de subalternização, referenciando argumentos raciais, sectários e xenófobos que associam práticas a certas nacionalidades/classes. O estudo também aborda o paralelismo entre migração e gênero, destacando conceitos como substituição, conciliação, implicação, redefinição ou apagamento. As limitações geográficas são problematizadas como mediadoras das relações sociais entre indivíduos de países diferentes, levando a interação humana a uma condição de semi porosidade de fronteiras, de onde ocorrem fluxos seletivos.

JUSTICE OF COMPENSATION FOR APPROPRIATION FOR THE PURPOSE OF OPENING ROADS IN JORDANIAN LAW (A COMPARATIVE STUDY)
Authors: Alsarayreh Mamdouh Mosleh Mamdouh
Published: May 2024

Objective: This study aims to define the concept of fair compensation, and how the Jordanian constitution gives the ordinary legislator the authority to determine the nature of fair compensation so that he may stipulate deducting part of the property free of charge, or did the constitutional legislator grant the ordinary legislator the authority to determine how to estimate the value of fair compensation as stated in Comparative legislation.
 
Theoretical Framework: The study employs a theoretical framework rooted in distributive justice theory, particularly drawing upon the perspectives of Rawls, Nozick, and Sen, the study evaluates the principles underlying fair compensation and its practical application in legal systems.
 
Design/Methodology/Approach: This study follows a comparative analytical descriptive approach in dealing with the position of comparative legislation on fair compensation in the first requirement, and we will devote the second requirement to the position of the Jordanian legislator on fair compensation stipulated in Jordanian legislation.
 
Result: The results of the study showed that appropriation for the public benefit has become recognized in constitutions and comparative legislations, as these legislations have defined the procedures for obtaining real estate to be appropriated in order to achieve the public benefit, and these legislations also included the principle of the owner's right to receive fair compensation that compensates the damage caused as a result of appropriation.
 
Research, Practical & Social Implications: The study concluded that the legislations have differed in how to estimate fair compensation, some of which stipulate that the compensation must be complete without taking into account the impact of ownership on the remaining parts of the property and neighboring properties, and some of which introduced the concept of a free quarter such as the Jordanian law of ownership in the acquisitions of roads. This study came to show the fairness of the free quarter deduction in the acquisition of roads in the Jordanian acquisition law compared to what is applied in the comparative legislation.
 
Originality/Value: The study provides original insights into the concept of fair compensation in Jordanian law, offering recommendations for legislative reforms to enhance distributive justice in expropriation cases.

Published: May 2024

El uso de la fuerza policial ha sido un tema presente en debates jurídicos y políticos, debido a un posible desconocimiento de sus límites, objetivos y certeza de eficacia, sin embargo, es importante mencionar que este proceder de la policía nacional ha ayudado al Estado a que garantice la protección de los derechos humanos de los ciudadanos, se les otorgue seguridad y prevalezca el orden público. El objetivo de esta investigación es analizar desde un punto de vista jurídico y doctrinario el proceder que tiene la policía ante disturbios en una sociedad, y realizar un análisis de derecho comparado con la legislación peruana, incluyendo el conocimiento de sus límites en el ejercicio de su profesión. La metodología para conocer este amplio tema es el enfoque cualitativo, aplicando los métodos histórico-lógico, descriptivo y recopilando fuentes documentales que han sido analizadas desde un punto de vista legal. Es realmente importante que se socialice de manera correcta el uso de la fuerza policial, para fomentar una relación armónica con la sociedad y que a su vez puedan actuar con el respaldo legislativo necesario cuando se trata de evitar el cometimiento de un delito.
