Solvability of a one-dimensional problem of fluid flow in poroelastic medium with permeable boundaries
Authors:   Altai State University, Papin Aleksandr A. , Tokareva Margarita A. ,   Altai State University
Published: October 2024

The initial-boundary value problem of a one-dimensional viscous fluid flow in a deformable viscous porous medium with permeable boundaries is considered. The governing equations are the equations of mass conservation for each phase, the equation of momentum conservation for a liquid phase in terms of Darcy’s law, the equation of momentum conservation for the whole system, and the rheological equation for porosity. The original system of equations in the Lagrange variables is reduced to a third-order equation for the porosity function. The first part of this paper presents the formulation of the problem, the definition of the classical solution to the considered problem, and the existence and uniqueness theorem for the problem of Hölder classes. In the second part of this paper, the local theorem of existence and uniqueness for the problem of Hölder classes is proved for an incompressible fluid using the Tikhonov-Schauder fixed-point theorem. The physical principle of the maximum porosity function is determined.

The article discusses the method of preconditioning of algebraic matrix equations without transforming the matrix of the right-hand side. The method is based on the technique of matrix zero divisors. The presence of the right (left) zero divisor is associated with linear dependence of the columns (rows) of the matrix. In this case, the problem of determining such preconditioning matrices is posed and solved, which, along with a decrease in the condition number of the matrix of coefficients on the left side, leave the matrix of coefficients on the right-hand side unchanged. The transformations consist solely in the rotation of the system around its exact, although still unknown, solution. This makes it possible to further improve the accuracy of determining the solution by eliminating possible computational errors in the transformation of the right-hand side of the matrix equation. It is shown that the choice of preconditioners, which make it possible to reduce the degree of conditionality of the equation, can be made on the basis of the method of simple iteration or taking into account the lower estimate of the condition number of the matrix on the left-hand side by fixing its eigenvalues using well-known and well-developed methods. The advantages of the proposed method are demonstrated by numerical examples. The reasoning given in the article regarding the left-handed matrix equation (the matrix of coefficients is on the left of the unknown matrix) is also valid for the right-handed and two-sided equations.
On automorphisms and derivations of reduced incidence algebras and coalgebras
Authors:   Tomsk State University, Krylov Piotr A. , Norbosambuev Tsyrendorzhi D. ,   Tomsk State University
Published: October 2024

Incidence algebras of partially ordered sets over commutative rings are an important and characteristic example of function rings. From a partially ordered set, one can obtain an incidence coalgebra. Using certain equivalence relations on the set of all intervals of a locally finite poset, reduced incidence algebras and reduced incidence coalgebras are defined. These objects have a much more complex structure compared to incidence algebras and incidence coalgebras. This article introduces two types of automorphisms of the reduced incidence algebra – multiplicative and order, as well as one type of derivations – additive derivation. As for incidence coalgebras, there are no works devoted to their automorphisms or derivations. The article discusses a possible approach to the study of automorphisms and derivations of incidence coalgebras.

Low-parametric equation of state for graphite describing solid and porous samples under shock and unloading waves
Authors:   Novosibirsk State University, Bel'kheeva Rumiya K.
Published: October 2024

This study is aimed to obtain the parameters of the graphite equation of state represented as the Mie–Grüneisen equation of state. Graphite with metals and the porous graphite are considered as simple thermodynamically equilibrium mixtures. The equilibrium state is determined by the conditions of equal pressure, temperature, and velocity of the components in the mixture. Thus, the motion of the multicomponent medium can be described as the motion of a continuum with a special equation of state that takes into account the properties of the mixture components and their concentration, which significantly reduces the number of equations. For the Grüneisen parameter, a logarithmic dependence on density is used, which adequately describes the variation in the Grüneisen parameter for both normal and anomalous behavior of shock adiabats. The increasing scope of the equation of state is a result of comparing experimental data with calculations for the following: 1) shock-wave loading of porous materials to cover the range of higher temperatures; 2) double compression of the samples to cover the range of increased densities; 3) isentropic expansion of samples to cover the range of low densities; and 4) sound velocities, which characterize the compressibility of matter, slope of the Poisson adiabat on the shock adiabat, and propagation velocity of the weak shock waves and unloading waves through the compressed matter. The comprehensive analysis confirms that the proposed model of the equation of state for graphite is applicable to practical applications.

This paper considers the interactions between two and three fullerenes using the methods of molecular dynamics. The results show that at a time step of one femtosecond, very high calculation accuracy can be achieved regarding the kinematic and energy parameters of the interaction. Thus, the details associated with the symmetry of the relative opposition of molecular objects are revealed, and the features and nature of the transition of two-dimensional motions of interacting objects into three-dimensional interaction of fullerenes are clarified, in particular, the interaction with the formation of a kinematic pair. The role of the initial spin of the fullerenes, which disables the transition of kinematic energy from the reservoir of translational energy into rotational energy, is also identified. This makes the formation of a kinematic pair impossible. In the general case, the triple collision of fullerenes is a complex process, in which, even in the special case of plane approximation, three phases can be distinguished: initial planar motion, multi-sheet spatial interaction of three objects, and a double spiral of interacting molecules with the linear motion of the discarded fullerene.
Features of the coagulation and fragmentation of drops in turbulent gas–liquid jets
Authors:   Moscow Aviation Institute (National Research University), Zuev Yuriy V.
Published: October 2024

In this paper, the mass exchange between drops of various sizes resulting from their coagulation and fragmentation in a two-phase jet is studied. Drops are combined into classes, and the drops of the isolated classes are assumed to consist of pure substances (components) in the initial cross-section of the jet. When moving away from the nozzle due to interparticle interaction, other components appear in the drops of all classes. The study of the variation in the component composition of drops makes it possible to analyze the intensity of mass exchange between drops and the ratio between coagulation and fragmentation of drops. Calculations have shown that coagulation and fragmentation of the drops occur simultaneously in the jet, but coagulation prevails over fragmentation. At a short distance from the nozzle, a significant change is observed in the fraction of components in the drops, and further their component composition remains constant. As the concentration of drops increases, the ratio between components in the drops tends to the ratio between the volume concentrations of the drops from the isolated classes in the initial cross-section of the jet.

Fault diagnosis method of automobile rolling bearing based on transfer learning and improved DenseNet
Authors: Lu Xinxin , Xiao Yang
Published: October 2024

Aiming at the problems caused by ignoring the time series characteristics, the scarcity of labeled data and the long diagnosis time in the fault diagnosis of one-dimensional vibration signals of automobile bearings, a new method combining improved DenseNet and transfer learning is proposed in this study. This method uses Recurrent Plot (RP) technology to convert one-dimensional vibration data into two-dimensional images to fully tap the potential value of time series. By optimizing the DenseNet network structure, the fault features are extracted effectively. Lightweight network design and MobileViT Attention mechanism are used to reduce the number of parameters and improve computing efficiency. With the help of transfer learning technology, the fault features in the source domain are transferred to the target domain, which solves the problem of cross-condition diagnosis and greatly reduces the diagnosis time. The experimental results show that the proposed method can improve the accuracy of fault identification and diagnosis efficiency, and achieve accurate classification.
DYNAMICS OF THE CLIMATE POLICY OF THE USA AT THE END OF THE XX – BEGINNING OF THE XXI CENTURY

Published: October 2024

The article notes that American climate policy, starting from the end of the 20th century. is characterized by cyclicality, which is caused by the opposition of republican and democratic party forces. In the opinion of the author, the greatest contrast appeared during the presidency of D. Trump, whose climate policy was a departure from the political priorities and goals of the previous administration of B. Obama. While President Obama's environmental agenda prioritized reducing carbon emissions through the use of renewable energy to preserve the environment for future generations, the Trump administration's policies envisioned achieving US energy independence based on the use of fossil fuels, for which many environmental regulations were repealed . Trump's climate policy has been defined by denying the consensus of the majority of scientists that climate change is caused by anthropogenic factors and will have catastrophic consequences, and that carbon dioxide is the main driver of climate change, and the decisions made have slowed down or deprioritized climate action. After the victory of Democrat D. Biden, adaptation and mitigation of the consequences of global climate change became one of the main components of his foreign and domestic policy. The author shows that despite the different views of Republicans and Democrats regarding the goals and tools of climate policy implementation at the national and regional levels, both political forces appealed to the protection of the country's national interests.

BACKGROUND: An increased risk of bleeding during rivaroxaban administration is associated with polymorphism of genes involved in its biotransformation, as well as with the use of drugs inhibiting shared metabolic pathways. However, the data are inconsistent.
AIM: To study specifics of drug-drug interactions between rivaroxaban and a P-glycoprotein inhibitor (using verapamil as an example) depending on the polymorphism of the CYP3A4 (rs35599367) and CYP3A5 (rs776746) genes in patients aged 80 years and older with non-valvular atrial fibrillation.
MATERIALS AND METHODS: A total of 128 patients (median age 87.5 years [83; 90], 75% women) were examined. All patients underwent genotyping for the studied gene variants, determination of the minimum steady-state concentration of rivaroxaban (Cmin, ss), standardization of the minimum steady-state concentration of rivaroxaban per daily dose (Cmin, ss/D), determination of prothrombin time in plasma, and analysis of medical documentation for the occurrence of clinically significant minor bleeding.
RESULTS: Compared to patients receiving rivaroxaban without calcium channel blockers, co-administration of rivaroxaban and verapamil in carriers of the CC variant of the CYP3A4 gene resulted in higher values of Cmin, ss (73.8 [49; 113.5] vs. 40.5 [25.6; 73.3] ng/mL), Cmin, ss/D (2.5 [1.7; 4.0] vs. 4.7 [2.9; 7.7] ng/mL/mg), prothrombin time (14.8 [13.3; 17.3] vs. 14.0 [12.6; 14.5] s) and clinically significant minor bleeding [10/30 (33.3%) vs. 6/45 (13.3%) cases], p 0.05. In carriers of the GG variant of the CYP3A5 gene, the same regimen resulted in higher values of Cmin, ss (74.7 [50.6; 108.8] vs. 40.2 [25.7; 72.3] ng/mL), Cmin, ss/D (4.6 [3.0; 7.3] vs. 2.5 [1.7; 4.0] ng/mL×mg), prothrombin time (14.6 [12.8; 15.2] vs. 14.0 [12.6; 14.5] s) and clinically significant minor bleeding [10/27 (37%) vs. 5/40 (12.5%) cases], p 0.05. Furthermore, in carriers of the GA+AA variant of the CYP3A5 gene, this regimen resulted in higher values of Cmin, ss (88.1 [5.5; 88.1] vs. 52.8 [25.0; 77.2] ng/mL), Cmin, ss/D (5.7 [0.4; 5.7] vs. 3.5 [1.7; 5.2] ng/mL×mg), p 0.05. The combined use of rivaroxaban with verapamil in carriers of the CT variant of the CYP3A4 gene was not observed in our sample.
CONCLUSIONS: Carriers of the homozygous wild-type CYP3A4/A5 genotype showed high pharmacokinetic variability to the administration of verapamil (a strong P-glycoprotein inhibitor and a moderate CYP3A4 inhibitor).

Indications and contraindications for transcranial magnetic therapy are outlined. The principles of prescribing various methods of transcranial magnetic therapy are covered in detail. The characteristics of the equipment used for transcranial magnetic therapy procedures are given.
In general, physical therapeutic factors play an important role in the overall complex of therapeutic and preventive measures in the treatment of eye diseases. As methods of external influence they have a direct impact on etiological and pathogenetic mechanisms, as well as on the symptoms of the disease.
Analyse de discours et inégalités sociales: de l’empathie pour les invisibles à l’engagement pour le commun
Authors: Rabatel Alain
Published: October 2024

Résumé: L’article analyse le lien entre inégalités sociales et invisibilité puis étudie quelques exemples de luttes de reconnaissance. Il interroge ensuite les précautions à prendre pour que l’analyse de discours rende compte de l’invisibilité sociale lorsqu’elle est redoublée par l’invisibilité médiatique et linguistique – avec des phénomènes d’effacement énonciatif, de naturalisation, de prise en compte énonciative qui ne vont pas jusqu’à la prise en charge. À cette fin, il liste des conditions épistémologiques, méthodologiques et théoriques faisant système concernant: l’articulation entre linguistique et réalité extralinguistique; la problématisation de la notion de représentation; le rapport des corpus marginaux à la norme; l’interprétation de la dualité marqué/non marqué en termes de continuums; la prise en compte des stratégies de communication formatées par les situations, par les choix discursifs révélateurs des intentions des locuteurs; une analyse de discours critique (aux antipodes des postures de dénonciation en appui sur des vérités monologiques); le choix de l’interdisciplinarité; l’analyse empathique – non seulement envers différents acteurs, mais envers des groupes, des façons de penser conflictuelles –, afin de pouvoir mieux penser la place et la contribution des uns et des autres dans la co-construction d’un (bien) commun partagé.  Mots-clés: Invisibilité sociale; mobilité empathique; engagement désengagé; commun; interdisciplinarité.Abstract: The paper first examines the relationship between social inequalities and invisibility as well as several examples of battles for recognition. It then raises the question of the precautions that should be taken so that discourse analysis illustrate social invisibility doubled by a media-related and linguistic invisibility – related to phenomena of enunciative effacement, naturalization, enunciative consideration which do not lead to commitment (“prise en charge”). In this respect, the paper enumerates the epistemological, methodological and theoretical conditions that are creating a system: the relationships between linguistics and extralinguistic reality; the problematization of the notion of representation; the relationships between marginal corpora and the norm; the interpretation of the marked/non-marked dichotomy in terms of continuums; the consideration of communication strategies formatted by situations and discursive choices revealing the speakers’ intentions; a critical discourse analysis (as opposed to the postures of denunciation supporting monological truths); the choice of interdisciplinarity; empathic analysis – not only towards different actors but towards groups or conflictual ways of thinking –, in order to better conceptualize everyone’s place and contribution in the co-construction of a shared common good.Keywords: Social Invisibility; Empathic Mobility; Disengaged Commitment; Commons; Interdisciplinarity.
Política, educação e desigualdades: três perspectivas, confinamentos e hibridizações
Authors: Duarte Marisa Ribeiro Teixeira
Published: October 2024

Reumo: O artigo sistematiza abordagens sobre política provenientes de três subáreas de conhecimento e que conduzem a compreensões diferenciadas das relações entre educação e desigualdades. A tradição sociológica francesa reconhece a origem do poder nas estruturas organizadoras das sociedades e o conhecimento sobre o poder advém do reconhecimento das estruturas sociais. A abordagem analítica, exposta por Arendt e Foucault no campo da filosofia política, reconhece o poder como promotor de ações concertadas. Sua efetividade requer a formação de consensos ou a adesão sincera dos agentes às regras sociais. Com a sociologia política de matriz weberiana, o poder decorre da apropriação de recursos diversos, que constroem a capacidade de uns em orientar o sentido da ação de outros. Por último, os estudos em políticas públicas, subárea analítica mais recente, onde o poder é apreendido como ação de atores conscientes que, ao expor seus interesses, formulam demandas. Cada subárea parte de ideias distintas para o estudo do fenômeno do “poder” e, ao longo do tempo, organizaram conceitos, categorias, discursos. As apropriações dessas abordagens nos estudos de política educacional têm consequências para as análises das relações entre educação e desigualdades e podem produzir tanto efeitos de confinamento, quanto de hibridismos.Palavras-chave: Educação e poder; educação e política; educação e desigualdades.Abstract: This article explores approaches to policy concerning three sub-areas of knowledge and leads to different understandings of the relationship between education and inequality. The French sociological tradition recognizes the power source in organizational structures of societies and the knowledge of power coming from the recognition of social structures. The analytical approach, espoused by Arendt and Foucault in the field of political philosophy, recognizes power as a promoter of concerted actions. Its effectiveness requires the formation of consensus or agents’ sincere adherence to social rules. With the political sociology of Weber, power stems from the ownership of various resources, building a capacity to guide the direction of the action of others. Finally, studies in public policy, the last analytical subarea, where power is perceived as the action of actors, who are aware that by exposing their interests, they formulate demands. Each area has different ideas for the study of the “power” phenomenon and, over time, of organized concepts, categories, and discourses. The appropriation of these approaches in educational policy studies have consequences for the analysis of the relationship between education and inequality and can produce both confinement effects as well as hybridisms.Keywords: Education and Power; Education and Policy; Education and Inequality.
Desigualdad de género en la política mexicana
Authors: Treviño María Eugenia Flores , Bonfiglio José María Infante
Published: October 2024

Resumen: La desigualdad social en México tiene distintas dimensiones. En la última reunión del Foro de Davos, se informó que México ocupa el lugar 111 de entre 138 países en cuanto a la participación de la mujer en política. No se trata del único tipo de desigualdad (THERBORN, 2015) que padecen las mujeres en México, pero sí, probablemente, una de las más perversas, dado que las leyes establecen el principio de igualdad de género para los cargos de elección, pero en las últimas elecciones (2015) para legisladores del orden nacional o federal los datos muestran que todavía falta mucho para alcanzar el 50% de los puestos. Este hecho señala la exclusión que permea en este ámbito social. Una de las causas de esa desigualdad puede situarse en el orden del discurso (FOUCAULT, 1970), donde se racionalizan y justifican las diferencias entre las normas jurídicas y los resultados en la determinación de la desigual distribución de los cargos legislativos y ejecutivos. En este trabajo, desde una perspectiva transdisciplinaria: comunicativo-pragmática y discursivoideológica, analizamos tres casos de discriminación sexista, divulgados en la prensa, contra candidatas en el periodo previo al proceso electoral (junio de 2015) en un estado del noreste mexicano: Nuevo León.Palabras clave: equidad de género; participación política femenina; elecciones en México; argumentación discursiva.Abstract: Social inequality in Mexico consists of different dimensions. In the last meeting of The World Economic Forum, it was informed that Mexico is ranked in the 118 position of 138 countries regarding the participation of women in politics. This is not the only inequality issue (THERBORN, 2015) women have to go through, but it might be the one of the most serious since laws establish a gender equality principle for the election charges. However, in the last elections (2015) for legislators in the national and federal levels, the available data show that women still have a lot to do to reach the 50% of the charges. This fact points out the exclusion which permeates this social field. One of reasons of such social inequality may be in the order of discourse (FOUCAULT, 1970), where it rationalizes and justifies the differences between the legal standards and the results in the determination of the unequal distribution of such charges. In this paper, we aim to analyze from a transdisciplinary perspective view: communicative-pragmatic and ideological-discursive issues, based on two cases of sexist discrimination disclosed in the press, against candidates in the last electoral process (June 2015) in a Mexican northeastern state: Nuevo León. Keywords: Genre Equality, Female Politics Participation, Elections in Mexico, Discursive Reasoning.
Use of cast index and three-point index in paediatric both bone forearm fractures: a prospective study
Authors: Kumar K. , Katariya C. , Jindal M. , Gupta P.
Published: October 2024

Introduction The majority of paediatric both bone forearm fractures are treated with manipulative reductions and casting; loss of reduction is one of the most commonly reported complications. We aimed to assess the role of cast index and 3-point index as predictor of outcome of a successful closed reduction in distal both bones forearm fractures.

Materials and methods This prospective observational study was conducted at the Department of  Orthopedics, Kalpana Chawala Government Medical College in Karnal to assess the role of cast index and  3-point index as predictor of outcome of a successful closed reduction in distal both bones forearm fractures. In the present study, 55 patients 16 years old were included irrespective of sex with distal both bones forearm fractures, managed by closed reduction and casting were included.

Results Fracture reduction failure was observed in 32.7 % of the patients. Both three-point index and cast index were found to be significantly higher in patients with reduction failure. It was observed that at 2 weeks Area under curve (ROC Curve) for Cast index and Three point index was 0.72 and 0.85 respectively. At 4 weeks, Area under curve for Cast index and Three point index was 0.77 and 0.84 respectively and at 6 weeks 0.74 and 0.86 respectively. Thus, in the present study, CI and 3PI had similar predictability for fracture reduction failure.

Discussion There are a few limitations of our study: We could not observe the patients for a longer period of time to know re-modelling in the long term. We did not take in to consideration the severity of fracture, type of anesthesia used (conscious sedation versus General Anesthesia) and the fracture configuration while assessing the outcomes. We also did not collect information about anthropometric parameters like child weight and diameter of the forearm.

Conclusion The three-point index and cast index are clinically useful tools to assess the quality of cast molding following closed reduction of pediatric forearm fractures and to predict re-displacement in distal forearm fractures.
Lateral cortical notching for impaired healing of extra-articular proximal femur fractures (case report)
Authors: Shafigulin R. A. , Akhtyamov I. F. , Aglyamov I. A. , Gornaev A. A.
Published: October 2024

Introduction Dynamization of the nail can be used to improve osteoreparation during intramedullary interlocking nailing (IIN). The procedure can be difficult to perform in some sub- and intertrochanteric femoral fractures due to anatomical and functional features.

The objective was to demonstrate a case of successful use of an original version of the lateral cortical notching (LCN) technique for dynamization of an intramedullary proximal nail in a patient with a nonunited subtrochanteric fracture.

Material and methods The treatment was performed for a 66-year-old patient with a non-united intertrochanteric fracture of the right femur complicated by the breakage of an intramedullary nail. The LCN technique was successfully used to dynamize the IM nail.

Results Radiological healing of the fracture and functional recovery of the patient were observed at a two-month follow-up. The absence of interfragmental compression in IIN could be caused by blocking of the sliding screw by the lateral cortical bone of the peripheral femur fragment. The complication could be prevented with LCN during primary osteosynthesis of the above fractures.

Discussion Based on scientific publications and our clinical experience, we assumed that LCN can be indicated for  failed healing of intertrochanteric AO/OTA 31A3.1–3 fractures, type 3 Boyd and Griffin trochanteric fractures and all types of subtrochanteric fractures as graded by Seinsheimer with a vector of interfragmental compression to be created along the femur axis during cephalomedullary osteosynthesis. The case report showed the mechanism of impaired consolidation in some intertrochanteric and subtrochanteric fractures of the femur.

Conclusion The case report demonstrateed the successful use of the original version of the lateral cortical notching (LCN) technique for dynamization of an intramedullary proximal nail.

Research aims: This study aims to determine the effect of perceived creativity, positive emotion, affective commitment on people intention to interact.Design/Methodology/Approach: The study procedures were carried out using a quantitative approach and data were collected with online questionnaires from July to December in 2023. The participants were selected using purposive sampling based on specific criteria, such as experience in purchasing products online. A total of 225 participants were selected and analysis was performed using Structural Equation Modelling (SEM) approach with SmartPLS.Research findings: The results showed that perceived creativity had a significant relationship on positive emotion and affective commitment. Positive emotion was shown to have a significant effect on interaction intention. However, perceived creativity had no significant impact on interaction intention of apparel brand. This indicated that creative content was inadequate in attracting Instagram users to interact with brand’s account. The results also showed that positive emotion lacked a significant correlation with affective commitment, while affective commitment had a significant relationship with interaction intention.Theoretical Contribution/Originality: This study provides meaningful contribution to Stimulus-Organism-Response theory by incorporating creativity to assess Instagram social media platform.Practitioners/Policy Implications: These results can assist business owners and social media marketers in developing creative marketing campaigns and building strong bond with their followers.Research Limitations/Implications: One of the limitations of this study is that it only assessed the use of Instagram in the fashion industry. Therefore, future studies are advised to explore different industries and recruit participants with a specific occupation to obtain better understanding of online consumer behavior.

O Brasil é o maior produtor mundial de laranjas e o principal exportador de seu suco. No cultivo de laranja, o pesticida clorpirifós, conhecido por sua alta toxicidade, é amplamente utilizado, com sua concentração não permitida a exceder 2 mg.kg-1. Embora a aplicação de clorpirifós seja proibida em muitos países, seu uso no Brasil está atualmente sob revisão. Portanto, desenvolver técnicas otimizadas e validadas para detectar este composto é crucial para a saúde pública e proteção ambiental. O método de Extração Líquido-Líquido de Partição em Baixa Temperatura (LTPLLE) provou ser uma alternativa eficiente para extração de pesticidas de diversas matrizes ambientais e alimentares. Este estudo teve como objetivo otimizar e validar o LTPLLE para extrair clorpirifós do suco de laranja, seguido de análise por Cromatografia Líquida de Alta Eficiência com detecção ultravioleta (HPLC-UV). A sustentabilidade do método foi avaliada usando a ecoescala analítica. A metodologia foi aplicada em amostras de suco de laranja adquiridas em supermercados e mercados de Itumbiara, Goiás. O método LTPLLE, otimizado e validado neste estudo, apresentou boa seletividade, linearidade (R2 > 0,99), alta exatidão e precisão, com taxas de recuperação acima de 90% e abaixo de 120%, e desvio padrão relativo (RSD) ≤ 20%. Em relação à ecoescala analítica, o método obteve pontuação 84, indicando um excelente perfil ambiental. A análise das amostras de suco comercializadas em Itumbiara-GO detectou 2,83 mg.kg-1 de clorpirifós em uma das amostras, valor que excede o limite máximo de resíduo estabelecido pela Agência Nacional de Vigilância Sanitária (ANVISA).
Parametric identification of coefficients for a model of fatigue stiffness degradation of a composite material

The problem of finding the fatigue characteristics of a composite material based on test results is considered. The results of endurance tests of unidirectional polymer composite materials with different initial stiffness, breaking stress and working cycle stress were used as the initial data. As a mathematical model of stiffness degradation, a nonlinear ordinary differential equation with five unknown parameters is used, reflecting characteristic changes in the properties of the material. It is required to find such parameter values that the solution of the differential equation should describe the available test results with sufficient accuracy. The solution procedure is reduced to the problem of optimizing the objective function, the value of which characterizes the achieved accuracy. As optimization methods, a method simulating the behavior of a flock of moths and a method of sequential reduction of the search set were used. A step-by-step algorithm for finding unknown model parameters is proposed, and numerical results of processing input data containing information on changing the elasticity modulus of the composite material in the course of applying load cycles are presented.

Published: October 2024

The last issue of Assessment News (Darr & Cosslett, 2024) outlined NZCER’s position on possible assessment policy directions that had been signalled by parties within the new coalition government. Since then, the Government has released a plan for consistent assessment, which requires all primary schools to use standardised assessment tools twice yearly. The PATs are one of three choices of assessment tools that schools can use for progression monitoring in Years 3–8. This edition of Assessment News is written by members of NZCER’s Assessment Services and Education Advisory teams. The team reflects on how they are going about providing the support needed to help schools to navigate the new policy settings and build assessment and data analysis capability according to where each school is at and what they want to achieve.

Published: October 2024

Objective:Metabolic syndrome (MetS) is significant public health concern with a rising prevalence. MetS leads to diseases such as diabetes mellitus, arterial hypertension (HTN) and atherosclerotic heart disease, as well as female sexual dysfunction (FSD). However, the relationship of MetS to female sexual function in obese woman is unclear. In our study, obese women and obese women with MetS were compared. We aimed to determine whether there was a difference between the two groups in terms of FSD.
Method:The study included 114 patients, aged 21-51, who visited the obesity outpatient clinic of our center from January to April 2022. Patients who met the study criteria answered the sociodemographic data questionnaire, Female Sexual Function Index (FSFI), and the Beck Depression Inventory (BDI). Anthropometric measurements and blood pressure assessments were conducted during the visit, and blood tests were recorded.
Results:Seventy-three (64%) patients were only obese, and 41 (36%) had a diagnosis of MetS with obesity. There was no significant difference between the two groups in terms of demographic data, clinical features, BDI scores, and FSFI total score. Lubrication, one of the FSFI subparameters, was found to be low in the group with MetS (p=0.028), while there was no difference in other subparameters.
Conclusions:In this study, we showed that lubrication as a sign of arousal problem is affected by MetS. Patients with risk factors for FSD such as MetS, obesity, HTN, diabetes mellitus should not be ignored. Thus, it will be possible to prevent the effects of FSD on general health.

Published: October 2024

Objective: This study was conducted to adapt the Self-Acceptance Scale for Pregnant Women (SAS-PW), which was developed in Brazil, to Turkish and test the psychometric properties of its Turkish version.
Method: This methodological study was carried out with 576 pregnant women who presented to the pregnancy outpatient clinics of a Research and Training Hospital in northern Turkey between December 2021 and April 2022. The validity of the Turkish version of SAS-PW was tested by conducting linguistic, content, and construct validity analyses, while its reliability was tested by conducting internal consistency and test-retest analyses.
Results: According to the results of the exploratory factor analysis, the factor load values of the items and the rates of the total variance in scale scores explained by the factors were sufficient. The confirmatory factor analysis results demonstrated that the goodness-of-fit indices of the scale were within suitable ranges. The 2-factor and 10-item construct of the original SAS-PW was confirmed based on the factor analyses. The item-total score correlations of the scale were found sufficient, and the total Cronbach’s alpha coefficient of SAS-PW was determined to be 0.93. The test-retest analysis of the scale scores revealed a strong correlation between the scores of the two implementations.
Conclusions: The Turkish version of SAS-PW is a valid and reliable measurement instrument to evaluate the self-acceptance levels of pregnant women in Turkish society.
