Numerical modeling of thrombus formation dynamics with the rheological properties of blood
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Maussumbekova Saule , Beketaeva Assel
Published: December 2024

In this paper, the dynamics of blood clotting is numerically simulated when blood viscosity changes. Blood was considered as an incompressible fluid, the initial equations were the Navier-Stokes equations supplemented by equations for the dynamics of blood clotting. Two cases for modeling blood viscosity are considered: viscosity as a constant and as a function characterizing non-Newtonian effects. The effects of the Reynolds and Peclet numbers on the process of thrombus formation are studied. As the Reynolds number increases, an increase in shear stress is observed. Increasing of platelet activation tends to thrombus formation. For the lower Reynolds number the better the transport of oxygen and nutrients prevents thrombus formation. Comparing the results obtained using the Cross model (viscosity is considered as a function of the velocity shear) with the results in the case of constant viscosity, it was found how increased blood viscosity leads to an increase in flow resistance, which requires a larger pressure gradient to maintain normal blood flow. High viscosity promotes platelet aggregation, increasing the likelihood of thrombus formation. Changing the Peclet number significantly affects the balance between convection and diffusion, which in turn affects the distribution of thrombin in the blood. The study of the rheological properties of blood and the blood coagulation process provides important information for improving medical diagnostics and treatment methods. The results of the work contribute to a deeper understanding of the influence of rheological properties of blood on the blood coagulation process, improving diagnostic and therapeutic methods in medical practice.

Published: December 2024

A significant disadvantage of the multi-point of view autostereoscopic method is a drop in image resolution with an increase in the number of points of view. An effective means of increasing the resolution is the use of an inclined lens raster and vertical encoding the colors of the point of view. Algorithmically simple coding is obtained at optimal tilt angles, the tangent of which is 1 divided by a multiple of 3 (1/3, 1/6, etc.). This requirement imposes significant restrictions on the coordination of the geometric parameters of the equipment – the display panel and the lens raster. The approaches to spatial color coding proposed in this article and the algorithms implementing them make it possible to significantly expand the possibilities of creating autostereoscopic displays. The experimental work carried out convincingly confirms the theoretical conclusions. The main practical result was the developed software that allows fine-tuning of the angle of inclination of the raster and calculating a multi-point of view parallaxpanoramogram for a specific set of equipment.

Authors: Bondareva N.A.
Published: December 2024

The paper provides a brief overview of generative neural networks and considers the role of information in training generative neural networks. In the digital environment, each object is surrounded by a vast information field, including unordered information and a set of references to it. The density of the object's information field determines the ability of technologies such as artificial intelligence to recreate its image based on the collected data. The more data is available, the more accurately and completely the digital image can be recreated. The paper considers a number of problems arising from the use of text-to-image networks and possible methods for solving them. The article considers various aspects of the role of personal data and possible ethical and social consequences in the era of generative technologies, as well as the prospects and risks of further development of generative neural networks in specialized areas such as medicine and manufacturing. The rapid development of neural network technologies can have a significant impact on education and social phenomena.

Authors: Chiruhin D.A. , Ryabinin K.V.
Published: December 2024

Recently, a large attention has been attracted to the brain-computer human-machine interfaces (BCI) based on electroencephalography (EEG). This emerging technology allows touchless control over digital systems, in which the commands are based on human brain activity. In the ideal case, it means controlling the systems virtually by thoughts, but in reality, also simpler approaches are highly demanded like reacting to concentration, relaxation, or specific emotions. Modern BCIs are based on detecting so-called brain waves, the electromagnetic field oscillations induced by brain neurons. These waves are captured by electrodes either intruded into the brain or placed on top of the head. Obviously, placing electrodes on the head is more demanded for non-medical applications of BCI because it is absolutely harmless for the person. To achieve this, special headsets are needed which can be put on the head like a helmet and ensure the correct positions for the electrodes mounted on them. In this regard, wearing comfort and anatomical accuracy of headsets play an important role in ensuring both ergonomics and precision of BCI. This paper focuses on automation of the personalized EEG headset manufacturing for BCI. The technological chain is proposed and corresponding software tools are developed to foster the complete cycle of BCI headset production for a particular person. The production steps include 3D scanning of the head, interactive editing of the electrodes’ location system, and automatic generation of a collapsible head cap model with sockets for EEG electrodes optimized for 3D printing. The performance of the pipeline has been validated in practice. The accuracy of electrodes’ placement has been evaluated by comparison with the head cap from professional medical equipment and is established as sufficient for BCI. The headset model editing and customizing tools are powered with scientific visualization and cognitive graphics techniques to be friendly for a wide range of users including those with no dedicated IT skills.
Relationship Self-Management Level of Hypertension Patients Towards Risk of Coronary Heart Disease
Authors: Pratiwi Jiheny Siska , Rahayu Sri
Published: December 2024

Most hypertension sufferers are not very strict in controlling themselves and managing their blood pressure to prevent complications. One of the significant risk factors for heart disease is hypertension. This study aims to ascertain if hypertension patients' degree of self-management and the prevalence of coronary heart disease are related. This specific type of research uses a cross-sectional study design and is quantitative. Purposive sampling is employed. The Slovin formula is used to compute the sample. The study's total sample was 109 outpatients with hypertension from the internal medicine polyclinic of Dr. Moewardi Surakarta Hospital. This study used the HSMBQ (Hypertension Self-Management Behavior Questionnaire) questionnaire by Nargis Akther to measure the level of self-management of hypertension with coronary heart disease. The data analysis used was a univariate test, and the risk level was calculated using the Framingham Risk Score and the chi-square bivariate test. Results show that the study's p-value=0.048 (<0.05) suggests a significant correlation between hypertension patients' degree of self-management and the prevalence of coronary heart disease. Most individuals fall into the category of having an adequate level of self-management. The majority of the 76 people (69.7%) with intermediate levels of self-management had a minor risk of coronary heart disease. The results of the study showed a significant relationship between the incidence of coronary heart disease and the level of self-control in hypertensive patients. Promotive and preventive efforts through educational approaches and structured interventions are essential to improve the quality of self-control in hypertensive patients.

What’s in a Name? The Presence of Feminist Foreign Policy in Aotearoa New Zealand
Authors:   , Bester Elzanne
Published: December 2024

The transformative potential of Feminist Foreign Policy (FFP) remains elusive despite its rising momentum. First conceptualised as a mechanism for integrating gender equality into foreign policy, FFP is now a contested paradigm with divergent normative underpinnings, balancing ethical ideals and policy pragmatism. The contribution of this thesis is twofold. First, building on theoretical and empirical scholarship, this thesis advances a critical FFP conceptual framework that departs from liberal FFP interpretations and embraces ethical and postcolonial logics. Second, using this conceptual framework, this thesis examines the extent to which Aotearoa’s foreign policy has transformative feminist underpinnings that align with critical FFP. This research addresses the question, to what extent is Aotearoa’s foreign policy feminist? To do this, the author examines the discourse and outcomes of Aotearoa’s foreign policy across all domains, including defence, humanitarian and development aid, trade and human rights policy from 2019–2023. This thesis finds that Aotearoa’s foreign policy sat at a crucial juncture. It demonstrated firm rhetorical commitments to gender mainstreaming and the feminist principles of gender equality, inclusivity, and human rights. However, critical gaps existed in Aotearoa’s implementation of these principles within its foreign policy practice. To champion a transformative feminist agenda, this thesis posits that Aotearoa’s foreign policy must address the power dynamics and gendered hierarchies across all areas of its foreign policy practice.

Transformation of Communication Ethics in the Context of Total Digitalization
Authors: Zamaraeva E. I.
Published: December 2024

The article is devoted to issues related to the transformation of communication ethics in the era of total digitalization. Its relevance is due to the fact that in the conditions of modern information wars it is necessary to maintain basic ethical norms that serve as the basis for the unity of society. The analysis of the sources made it possible to identify the characteristic features of the so-called “digital” generation: a change in the usual way of thinking and a decrease in intellectual abilities, rejection of book culture, inability to perceive traditional texts, lack of conceptual thinking. The author notes that the digital environment simplifies thinking, forms clip consciousness and does not contribute to the development of critical thinking. This creates favorable conditions for the spread of so-called “mental viruses”. In addition, social platforms enhance the segmentation of society by creating new forms of trust. The digital space is becoming an aggressive social field and an ideal tool for manipulating consciousness. The analysis of the digital environment has revealed a number of its features: the viral potential of online communications, the active participation of commentators, as well as the extensive multimedia potential of Internet resources that make them attractive (graphics, video, animation, simplified presentation of information). The transformation of communications in the context of information wars poses a threat to a complete “rewiring” of consciousness, which can lead to the destruction of the country’s social security. The author suggests the following measures to counter this threat: the development of a full-fledged state policy to preserve basic ethical standards, uniting the efforts of all participants in social interaction; state censorship; comprehensive state control over the activities of digital giants; the creation of special digital ethical programs. The article is intended for educational professionals, researchers and all interested parties.

Published: December 2024

Purpose: Radio-Tartaglia syndrome (RTS; Mendelian Inheritance in Man [MIM]: 619312) is a rare neurodevelopmental disorder with few reported cases and limited research. It has recently been reported that the clinical features of RTS overlap with those of 1p36 deletion syndrome (1p36DS), a common chromosomal deletion characterized by clinical and molecular heterogeneity. This study aims to report on a Korean patient with RTS and compare the clinical and molecular features with those of patients with 1p36DS.Methods: A 3-year-old boy was brought to the hospital and underwent whole genome sequencing to evaluate developmental delay and multiple anomalies. This led to the identification of a de novo truncating variant in SPEN. We retrospectively investigated cases of 1p36DS that were either newly diagnosed at our institution or previously reported in the literature and databases.Results: The clinical profile of RTS includes developmental delay/intellectual disability, hypotonia, feeding difficulties, congenital heart defects, and facial dysmorphisms. SPEN is frequently found within the deleted region associated with 1p36DS. However, in all reported Korean cases of 1p36DS, the deletions were distal and did not involve SPEN; despite this, the clinical features of the disorder overlap considerably with those of RTS.Conclusion: SPEN is a newly identified gene that plays a role in various developmental processes. Therefore, it is essential to include SPEN in genetic testing when diagnosing patients suspected of having a neurodevelopmental disorder. Additional research is required to explore the molecular and clinical features, as well as the prognosis, of patients with either an isolated SPEN mutation or one that co-occurs with 1p36DS.

Comprehensive multiscale study of fatigue crack kinetics (FCK) in aircraft engine disks and samples from heat-resistant titanium and nickel alloys is presented. The aim of the studies was to determine the possibility of microfractographic reconstitution and calculated prediction of stable fatigue crack growth based on the measurement and calculation of fatigue striation spacing S. The studies included micro- and macrofractographic measurements of stable crack growth (according to fatigue striation spacing, measured by scanning electron microscopy with high resolution, and to the marker lines determining positions of the crack macrofront after a certain number of loading cycles) and comparing their results, finite element modeling of cracks and calculating the stress intensity factor (SIF) range ΔK, calculated prediction of FCK using kinetic equation S(ΔK), obtained earlier on the basis of physical and mathematical modeling of stable fatigue crack growth mechanism, comparison of prediction results with fractographic data. Because of the study, it is shown that the average value of S characterizes fatigue crack growth rate (FCGR) during the entire stage of stable growth of the fatigue crack, corresponding to the second section of the kinetic diagram «FCGR – SIF range». The use of equation S(ΔK) makes it possible to predict the stable growth of fatigue cracks of different configurations in parts and specimens from structural materials with different crystal structure and microstructure under different loading conditions. The obtained results are of particular importance for ensuring safe operation of high-stress rotary parts of aero engines, in which the duration of stable growth of low cycle fatigue cracks reaches 70 % of the total cyclic life, and fatigue striation spacing is the only measurable characteristic of stable growth rate under service conditions.

Authors: Keltsieva O. A. , Podolskaya E. P.
Published: December 2024

The aim of this work was to develop, characterize and apply in a laboratory-on-plate format a new metal-affinity sorbent based on cobalt (II) stearate thin monolayers (films) — FCo. FCo were prepared by the classical Langmuir method and then collapsed. A bath with movable barriers was filled with an aqueous solution of CoCl2. A solution of stearic acid in hexane was dropwise applied to the surface of the aqueous subphase. The solution spread over the surface, forming a film (layer). After evaporation of hexane from the aqueous subphase, a monolayer of cobalt (II) stearate was formed on the surface, which was slowly compressed by movable barriers. The following parameters were determined for FCo prepared by the classical Langmuir method and then collapsed: specific mass (0.022 ± 0.003 mg/dm2), specific surface area (22.0 ± 2.1 m2/g), isoelectric point value (3.7 pH), moisture content (63 ± 2%), structures ([Co(C17H35COO)2]H+), chemical stability (stable in standard aqueous eluents and in polar organic solvents used in metal-affinity chromatography). Adsorption isotherm of the diclofenac from aqueous solution on FCo was investigated in spin columns (batch). The FCo structure can be obtained on the surface of a subphase drop deposited on a MALDI target plate. Thus the sorbent is formed directly on the surface, preserving the structure and metal-affinity properties. The technique is characterized by cost-effectiveness, simplicity and reproducibility. FCo formed on spot of MALDI target plate provide a high level of sensitivity, specificity and selectivity of the analysis, it is shown that HHb adducts with chlorine-containing alkylating agent can be determined at 0.5% protein modification. Thus, a comprehensive approach for the enrichment of chlorine-containing HHb adducts using a cobalt (II) stearate monolayers on MALDI target plate has been developed.

Published: December 2024

This study examines the strategic impact of village fund management on the performance of village governments in Madiun Regency, Indonesia. Using a sample of 27 villages and 80 respondents, including village heads, secretaries, and financial officers, the research investigates how planning, implementation, transparency, and accountability affect governmental performance. Data were collected through documentation and questionnaires and analyzed using multiple linear regression. The results show that both planning and accountability have a positive and significant influence on village government performance, while implementation also contributes positively. However, transparency does not significantly impact performance. The findings suggest that improving planning and accountability processes is essential for enhancing the effectiveness of village governance. In contrast, transparency efforts, while important, may not directly lead to performance improvements in this context. The study highlights the need for better public access to information and more active participation in performance evaluations to further enhance village fund management and its outcomes.

Experimental and theoretical study of catalytic and radiative characteristics of anti-oxidation and anti-erosion coatings for high-speed aircraft
Authors: Tushavina O. V.
Published: December 2024

The catalytic activity coefficient and emissivity of the surface of thin-walled oxidation- and erosion-resistant coatings for high-speed aircraft were determined experimentally and theoretically. The coating was applied as an aerosol mixture to a carbon-carbon composite substrate, and the resulting sample was subjected to fully dissociated air to measure heat fluxes to the sample surface and its enthalpy. Using established relationships between total convective-diffusive heat fluxes, stagnation enthalpy, and the heterogeneous recombination coefficient of oxygen and nitrogen atoms into molecules, the catalytic activity coefficient and surface emissivity were calculated based on the Stefan–Boltzmann law utilizing the measured enthalpy (and temperature) of the wall. The experiments were performed on five coating types containing silicon, titanium, molybdenum, and boron. The findings were summarized in a table showing how the recombination coefficient and emissivity depend on heat fluxes and wall temperature.

Visando o aumento da produtividade do morango e também o aumento da eficiência dos fertilizantes fosfatados, novas tecnologias para adubação vêm sendo testadas, destacando os fertilizantes organominerais, provenientes da mistura de fertilizantes minerais e orgânicos. Assim sendo, este trabalho objetivou avaliar a produção de cultivares de morango adubados com fertilizantes fosfatados. O experimento foi realizado entre os meses de maio a outubro de 2019 sob cultivo protegido em vasos. Utilizou-se o delineamento experimental em blocos ao acaso, com cinco tratamentos compostos por fertilizantes (organomineral peletizado 07-30-00, organomineral granulado 07-30-00, MAP, superfosfato simples e ausência de adubação) e duas cultivares de morango (San Andreas e Monterrey) com quatro repetições. O solo utilizado foi caracterizado como Latossolo amarelo distrófico de textura franco argilo-siltosa. Aos 120 dias após o transplantio, iniciaram as colheitas dos frutos sendo avaliadas as características físicas (número total, massa média total, peso total), perda de água dos frutos e massa seca da parte aérea e raízes. Os fertilizantes organominerais peletizado e farelado promoveram o maior desempenho para todas as variáveis avaliadas, produzindo maior quantidade de frutos e maior acúmulo de matéria seca de parte aérea e raiz das plantas de morangueiro. Com isso, podemos concluir que a adubação organomineral foi eficiente, proporcionando melhor crescimento e produção de frutos do morangueiro, sendo os resultados mais expressivos para a cultivar San Andreas.

A ativação de mecanismos de defesa vegetal é um método alternativo ao uso de pesticidas para o controle de doenças em plantas. Vários produtos, incluindo alguns metais, podem agir como eliciadores dessa defesa. O objetivo deste estudo foi utilizar aminoácidos quelatados à base de cobre, zinco, manganês e cálcio para induzir a síntese de fitoalexinas em feijão, soja e sorgo. Os quelatos foram utilizados nas concentrações de 0,1%, 0,5%, 1%, 2,5% e 5% (volume/volume) a partir de produto comercial e para a testemunha foi utilizada água destilada. O ensaio para produção da fitoalexina faseolina foi realizado em hipocótilos estiolados de feijão, o ensaio para produção da fitoalexina gliceolina foi em cotilédones de soja e o ensaio para a produção das fitoalexinas 3-deoxiantocianidinas foi em mesocótilos estiolados de sorgo. As fitoalexinas produzidas foram mensuradas em espectrofotômetro a 280 nm, 285 nm e 480 nm, respectivamente para feijão, soja e sorgo. Os dados foram submetidos à análise de variância e regressão. Houve efeito indutor de resistência pela ativação da síntese das fitoalexinas nas três culturas. Para feijão, todos os quelatos apresentaram efeito indutor de maneira dose-depende. Para soja, o quelato de manganês apresentou maior efeito indutor na dose calculada de 3,4%, o quelato de cálcio apresentou efeito indutor de maneira dose-dependente, não havendo indução a partir dos quelatos de cobre e zinco. Para sorgo, os quelatos de cobre, zinco, manganês e cálcio apresentaram efeito indutor, sendo a maior indução nas doses calculadas de 3,69%, 3,47%, 3,49% e 3,68%, respectivamente.

A cultura do alho é altamente exigente em adubação, o que encarece o seu custo de produção, e a busca por alternativas que possibilitem manter índices produtivos a um menor custo e de maneira sustentável devem ser incentivadas. Dessa maneira, o objetivo deste trabalho foi avaliar a resposta da cultura do alho à coinoculação com Azospirillum brasilense e Pseudomonas fluorescens associada à redução da adubação com NPK. O experimento foi conduzido no munícipio de Brunópolis – SC em um delineamento em blocos casualizados com cinco tratamentos, sendo T1: 100% NPK; T2: 75% NPK; T3: 75% NPK + 0,5 L ha-1 de inoculante; T4: 75% NPK + 1,0 L ha-1 de inoculante; T5: 75% NPK + 1,5 L ha-1 de inoculante. Foi avaliada a altura de plantas aos 20, 60 e 110 dias após o plantio, além da coleta de dados no período pré-cura para determinar diâmetro de bulbo, massa de plantas frescas, estatura, diâmetro de pseudocaule e número de folhas. No período pós-cura foram avaliados diâmetro de bulbo, número de bulbilhos, massa de bulbos, massa da parte aérea pós-cura e produtividade. Os dados obtidos foram submetidos à análise de variância e as médias foram separadas pelo teste de Scott-Knott a 5% de probabilidade de erro. A variável número de bulbilhos foi a que apresentou melhor resposta à coinoculação, com média de 6,5 bulbilho por bulbo ao utilizar-se 1,5L ha-1 de inoculante e 75% NPK. As demais variáveis tiveram efeito da coinoculação. A inoculação apresenta potencial de melhorar características produtivas do alho e reduzir a adubação, mostrando-se uma metodologia importante para a agricultura sustentável.

A adubação nitrogenada é um fator essencial para o desenvolvimento vegetal, especialmente em plantas cujo produto comercial são as folhas, como por exemplo a alface (Lactuca sativa). O objetivo desse trabalho foi avaliar a produção de alface crespa com diferentes fontes de nitrogênio. Foram utilizadas plantas da cultivar Vera (grupo crespa). O experimento foi desenvolvido a campo em Pinhalzinho/SC, no verão de 2022/23 e foi conduzido em delineamento de blocos casualizados (DBC). Os tratamentos foram: controle (cultivo sem adubação nitrogenada); adubo orgânico (composto de ave); adubo químico (fonte ureia) e; aplicação de nitrato de cálcio. Foram avaliados o número de folhas, massa fresca, e produtividade. Os dados foram submetidos à análise de variância e comparação de médias pelo teste de Tukey (p<0,05). Os melhores resultados para a produção da alface cultivar Vera, foram encontrados com a aplicação do adubo orgânico. A fonte de nitrogênio orgânica, derivada do composto de aves, propiciou o melhor desempenho para número de folhas por planta, massa fresca e produtividade total, mostrando-se uma alternativa interessante como fertilizante no cultivo de alface.

O fósforo (P) é um macronutriente primário fundamental para o desenvolvimento das plantas, influenciando em vários processos. Contudo, a adsorção do P no solo, é um fator crucial para a disponibilidade desses nutrientes para as plantas, podendo ser influenciado por atributos químicos e físicos do solo. Nesse contexto, este trabalho teve como objetivo avaliar a capacidade máxima de adsorção de fósforo (CMAP) dos solos de Alagoas e sua relação com os atributos químicos do solo (pH, P, P-rem, K, Na, H+Al, Ca, Mg, Al, M.O) e CMAP ajustadas a isotermas de Langmuir. Os resultados indicam variação na capacidade de fixação de P, com atributos como matéria orgânica, CTC e acidez potencial mostrando correlação significativa com a CMAP, influenciando a disponibilidade de P nos solos.

Este estudo buscou comparar os índices espectrais NDVI e NDRE, considerando as características específicas de diferentes sensores. O estudo foi realizado em uma área experimental do Campus de Engenharias e Ciências Agrárias CECA/UFAL, situado no município de Rio Largo, AL. Foi realizado um imageamento com o drone Mavic 3M DJI e adquiridas imagens multiespectrais dos satélites Sentinel Hub e PlanetScope. A partir dos ortomosaicos do drone e das imagens de satélite, foram calculados os índices utilizando o software QGIS. Os ortomosaicos, com resolução espacial de 3 cm, proporcionaram uma análise detalhada das variações nos tons de verde ao vermelho, com os valores de NDVI variando entre -0,270587 e 0,859991. A análise dos coeficientes de variação (CV) indicou dispersão elevada e baixa representatividade da média para o NDVI da PlanetScope e para o NDRE da Sentinel Hub e do drone, cujos CVs foram 0,40 e 0,26, respectivamente. Em contraste, CVs mais baixos, como no NDVI do Sentinel e drone (-0,07 e 0,24), tiveram maior representatividade. Além disso, o NDRE do PlanetScope apresentou um CV baixo. Os resultados deste estudo ressaltam a importância do uso combinado dos índices espectrais NDVI e NDRE para a agricultura de precisão. Esta combinação dos índices NDVI e NDRE, aliada à análise em múltiplas escalas e resoluções, oferece uma compreensão mais abrangente da dinâmica vegetativa.
