Effect of the chemical composition of aluminium alloy EN AW-2024 on the strengthening state after T6 and T6I6 treatment
Authors: Staszczyk A. , Lipa S. , Adamczyk-Cieślak B. , Sawicki J.
Published: December 2024

The work focuses on comparing three EN AW-2024 aluminium alloys with different chemical compositions within the standard limits to understand the influence of the chemical composition on the mechanical properties obtained. The study discusses the correlations between intermittent ageing processes and the improved strength, hardness, and fatigue resistance of some alloys compared to traditional aging processes.To understand how the chemical composition affects the mechanical properties, each alloy underwent T6I6 treatment (intermittent ageing with a weekly break) compared to traditional T6 treatment. The study involved SEM and TEM microscopic observations, as well as EDS tests to analyse the chemical composition, hardness, and uniaxial tensile testing.In the research conducted, both SEM and TEM microscopic observations revealed a similar percentage of intermetallic phase particles in the alloys. However, there were significant differences in the size and distribution of the particles. The alloy with the maximum Fe and Si content showed the highest particle refinement. Despite the observed differences in microstructure, the tests for Young's modulus, yield strength, and strength were found to be the same or very similar and were not influenced by the alloy processing process. The only notable difference in the strength parameters was the parameter marked as elongation in the direction of tension, with its lowest value observed in the alloy with the highest Si content.The issue that arose during the analysis is accurately evaluating the alloy's morphology, particularly defining the three-dimensionality of the resulting phases using TEM. To conduct a more comprehensive analysis, additional tests need to be performed for statistical significance. In the future, SEM and TEM analyses and real-time tensile tests on specially prepared samples under the microscope would be beneficial.The work presented addresses whether the chemical composition of the standard area plays a crucial role in achieving consistent mechanical properties of the aluminium alloy after the ageing processes. Despite the observed structural differences, the material's mechanical properties remained unchanged. This information is valuable for process design.Comparison of mechanical properties, morphology, and phases formed after the ageing process of alloys of the same grade with minor differences in chemical composition.

Published: December 2024

The paper aims to analyse the AI adoption at the company/country level and the efforts made to achieve this objective. The necessary changes for the use of AI solutions involve not only a significant financial effort, but also attracting talent, building adequate infrastructure, getting governmental support and, above all, consistent investments in research and development at the company/country level. The paper presents the key elements of the measurement process used in calculating the Global AI Index, as well as the results for 62 countries, having as an original contribution the creation, training and testing of a machine learning algorithm, aiming to extrapolate the AI Global Index. Also, the purpose of the paper is to demonstrate that AI machine-learning models can be created, trained and tested to achieve a higher accuracy of forecasting and can be used regularly in the decision-making process. The scientific journey was possible due to open access to the data used to determine the AI Global Index, as well as to the use of collective experience and wisdom (e.g. Google Colab and Python programming language). Even though the results have just a demonstrative value encourages the research expansion to calculate the Global AI Index for Romania, a country which is not listed among the 62 countries for which the Global AI Index was calculated in 2023.

ESTUDOS DE FLUXO DE CARGA, CURTO-CIRCUITO TRIFÁSICO E ANÁLISE DINÂMICA EM SISTEMAS ELÉTRICOS DE POTÊNCIA
Authors: Borges Guilherme de Azevedo , Magalhães Alana da Silva
Published: December 2024

INTRODUCTION: The study of load or power flow in electrical systems is essential to design the infrastructure and predict the required voltages, currents and powers. The 2018 IEEE Std 3002.2 standard (IEEE, 2018) allows you to simulate situations that could hardly be safely tested in the real world. In addition, this type of analysis makes it possible to identify problems related to system loss, loading of new equipment, and other occurrences. One of them is the occurrence of faults in electrical systems that result in large variations in the currents and voltage of the three-phase network. Thus, dynamic analyses allow the study of short circuits in these systems while statistical analyses focus on the charge flow. This discussion is based on standardized technical norms to obtain a reliable theoretical basis for the procedures used in academic studies on this important topic of electrical engineering.

Published: December 2024

A gestação é um processo complexo, que envolve uma série de mudanças fisiológicas e psicológicas no corpo da mulher, visando a preparação para o desenvolvimento e o nascimento do bebê. Este estudo objetivou verificar a relação entre nível de suporte social, autoestima e variáveis sociodemográficas em um grupo de gestantes. Trata-se de um estudo transversal, onde foram avaliadas 94 mulheres grávidas, maiores de 18 anos, em todas as fases da gestação. Os dados foram obtidos por meio de um questionário sociodemográfico, pela Escala de Autoestima de Rosenberg e pela Escala Multidimensional de Suporte Social Percebido. A análise dos dados foi realizada por meio de estatística não-paramétrica, adotando-se como nível de significância 5%. Os resultados indicaram que as variáveis idade materna, idade gestacional e trimestre da gestação não se correlacionaram com níveis de autoestima e suporte social. As variáveis que se mostraram significativamente associadas com a autoestima e suporte social foram a situação conjugal e o planejamento prévio da gravidez. A variável classe econômica mostrou correlação positiva com autoestima e suporte social, entretanto de intensidade fraca. Já a variável autoestima se mostrou fortemente correlacionada com suporte social. Conclui-se que é necessário considerar a importância que uma rede de suporte social e apoio contínuo possuem para as gestantes, no intuito de garantir sua saúde mental. Desse modo, políticas públicas voltadas para gestantes deveriam sempre considerar o acompanhamento e a avaliação de variáveis psicossociais no pré-natal, ajudando a garantir um bom desenvolvimento físico e emocional da díade mãe-bebê.
KÜLTÜREL ANTROPOLOJİ BAĞLAMINDA ANTİK YUNAN’DA MÜZİĞİN BÜYÜSÜ VE ORFİZM
Authors: Erol Berfin Irmak , Dilek Yeşim
Published: December 2024

Sosyal ve Kültürel Antropoloji disiplini sosyal bilimlerin önemli çalışma konularından biri olan büyü fenomenini, toplumsal örgütlenme dinamikleriyle birlikte açıklamaya çalışmış ve büyü kavramının dini inanç sistemlerine ne şekilde sirayet ettiğine odaklanmıştır. Büyü meselesine dair bu yaklaşım büyü yapabilme gücü ya da hakkı olan kimselerin toplum nezdindeki otoritelerini sorgulatmış ve bu gücün ya da hakkın kaynağı aranmıştır. Büyücülük ‘‘özüne’’ sahip olduğu düşünülen bu kişiler, bir sözü, nesneyi ya da simgeyi aracı olarak sunup, doğaüstüyle iletişim kurmuş ve insanüstü özellikler göstermişlerdir. Antik Yunan’da kimilerine göre gerçekten yaşamış olan kimilerine göre de yalnızca mistik bir kişi olan Orpheus, Apollon’un hediye ettiği ve ustaca çaldığı liri ile büyüleyici şarkılar söyleyerek ölümlü bir insanın yapamayacağı şeyleri yapmıştır. Heracles ve Odysseus gibi Tartaros’a inip, yeryüzüne geri gelen nadir karakterlerden biri olmuş ve bunu büyüleyen savaşçı öyküsüyle değil, çok sevdiği karısının ölümünü kabullenmeyip onu geri getirmek istemesi sebebiyle başarmıştır. Bu vesileyle ölümle tanışıklığı onu, ölüm sonrası ve ölümsüzlük hakkında düşünmeye sevk etmiş ve onun fikirlerini, deneyimlerini benimseyerek örgütlenen gizemli bir dinin ortaya çıkmasında etkili olmuştur. Bu çalışmanın amacı, Orfizm olarak adlandırılan bu inanç biçiminin antropolojik çözümlenmesini yapmak olmuştur. Bu çözümlemede Antik Yunan toplumunun müziğe atfettiği kutsiyetinin anlamı dikkate alınmış, Orpheus’un dini bir otoriteye dönüşmesinin sebepleri ölüm ve büyü ekseninde incelenmeye tabii tutulmuştur.

Published: December 2024

Witnessing the evolving context of the work phenomenon, we can see that the existence of generations has created increasingly complex dynamics. Job hopping has become one of the most prevalent work phenomena among Generation Z. Psychological reasons require generation Z to often reorganize their future job prospects. The expectations that arise in the minds of generation Z employees are related to the role of psychological capital and perceived  of organizational support on individual desires to change places (job hopping). This study was created to expand knowledge about the deeper relationship between psychological capital and perceived organizational support on job hopping intention. To obtain information and research data sources, purposive sampling techniques were used and a sample of 145 respondents was then distributed through questionnaire data collection techniques with criteria in the form of generation Z employees who work in conventional companies in the Surabaya City area. The data analysis technique used is Partial Least Square (PLS), where the results show that psychological capital has a negative and significant effect on job hopping intention while perceived organizational support also has a negative and significant effect on job hopping intention. This means that the higher the level of psychological capital and perceived organizational support, the lower the level of job hopping intention of employees.

Authors: Chong Cara
Published: December 2024

In Guatemala, the blend of indigenous and modern cultures significantly influences the social factors affecting women's health. This research explores how these cultural interactions shape access to healthcare, the quality of services, and health outcomes for women. By examining the traditional health practices and beliefs of indigenous communities alongside contemporary medical methods, we reveal important disparities and opportunities for integration. The study also looks into how social determinants like education, economic status, and gender norms impact women's health. The goal is to provide insights that can guide the development of culturally sensitive health policies and programs aimed at enhancing healthcare delivery and outcomes for women in Guatemala. The current findings suggest that integrating Mayan traditional medicine with the modern healthcare system could offer a culturally respectful and comprehensive approach to addressing reproductive health disparities in Guatemala. This integration's implications for indigenous and contemporary healthcare practices might be noticed.

Published: December 2024

The hepatoprotective activity of hydroalcoholic leaf extract of Ocimum gratissimum was evaluated against liver damage induced by atorvastatin and clopidogrel in rats. Atorvastatin and clopidogrel were administered intraperitoneally at doses of 80 mg/kg and 20 mg/kg, respectively, for 14 days, while the leaf extract was given orally at doses of 100 mg/kg, 200 mg/kg, and 400 mg/kg over the same period. Biochemical markers, including serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), serum alkaline phosphatase (ALP), and total protein, were assessed to determine the extract's impact on drug-induced liver damage. Animals treated with the hydroalcoholic extract exhibited a significant reduction in serum marker levels, suggesting improved hepatocyte function. Conversely, elevated marker levels were observed in the atorvastatin and clopidogrel group, indicating severe hepatic damage. Silymarin (100 mg/kg) was used as a standard reference drug. The findings demonstrate that the hydroalcoholic leaf extract of Ocimum gratissimum offers significant hepatoprotection against atorvastatin and clopidogrel-induced liver damage.
Keeoukaywin: The Visiting Way - Fostering an Indigenous Research Methodology
Authors: Gaudet Janice Cindy
Published: December 2024

Decolonizing research methodologies are increasingly becoming the forefront of research with, for and/or by Indigenous peoples. This paper aims to highlight an Indigenous research methodology that emerged from a Metis researcher’s relation with Omushkego people from Moose Cree First Nation (Moose Factory, Ontario, Canada) during my doctoral research from 2012 to 2016. The contents of the article represent a decolonizing process of doing research with a broader research aim to make links between land-based pedagogy and milo pimatisiwin (good life). It is with the Omushkego people of Moose Cree First Nation and how the community itself led me to remember, to reclaim and to regenerate what I came to identity as Keeoukaywin meaning the Visiting Way. With relationality at its core, the Visiting Way - Keeoukaywin - re-centers Metis and Cree ways of being as a practical and meaningful methodology to foster milo pimatisiwin, living and being well in relation. The study shows how an Indigenous research methodology promotes self-recognition in relation to the land, history, community and values and demystifies our own epistemic relation to historical truths.

Published: December 2024

El cáncer y la tuberculosis son dos de las enfermedades que más afectan a la salud en todo el mundo. La tuberculosis es una enfermedad infecciosa crónica causada por la bacteria Mycobacterium tuberculosis, que puede manifestarse desde la enfermedad pulmonar cavitaria hasta la infección focal que afecta a casi cualquier órgano y la infección ampliamente diseminada. La tuberculosis y el cáncer tienen una relación compleja, por un lado, la quimioterapia, la radioterapia y la cirugía a largo plazo debilitan el sistema inmunológico de los pacientes oncológicos aumentando el riesgo de infección, y por otro lado, la tuberculosis pulmonar se asocia a un mayor riesgo de desarrollar cáncer de pulmón a través de la inflamación pulmonar crónica, cambios genómicos y la fibrosis. Se presentó el caso clínico de una mujer de 47 años de edad, con antecedente de carcinoma papilar de tiroides estadio IV por metástasis pulmonares, estenosis traqueal y parálisis de la cuerda vocal izquierda, a la cual se le diagnosticó tuberculosis pulmonar mediante las manifestaciones clínicas y lavado bronquioalveolar con la prueba Xpert®MTB/RIF ultra. El proceso metodológico constó de la anamnesis, examen físico, revisión de la historia clínica, y exámenes de laboratorio e imagen. Se concluyó que la identificación y manejo oportuno de la tuberculosis en pacientes oncológicos es esencial, no solo para el bienestar del paciente, sino también para la salud pública, dado el potencial de diseminación de la enfermedad en poblaciones vulnerables.

DO BIRDS OF A FEATHER FLOCK TOGETHER? A FIT THEORY PERSPECTIVE ON LMX QUALITY AND RATEE FEEDBACK REACTIONS
Authors: Khan Tamania , Iqbal Muhammad Zahid
Published: December 2024

This study seeks to understand the role of rater–ratee personality configurations in relational and employee outcomes. Specifically, it examines the effect of the interplay between rater–ratee honesty–humility (H-factor) on ratee feedback reactions via leader–member exchange (LMX). Data collected from N = 310 matched dyads were analyzed using polynomial regression. The findings indicated that rater–ratee H-factor congruence was more accurate in predicting LMX and ratee feedback reactions compared with H-factor incongruence. Congruence at both high and low levels of H-factor was found to affect LMX and ratee feedback reactions positively. Different magnitudes of incongruences exhibited negative impacts on LMX and ratee feedback reactions. LMX also mediated the relationship between rater–ratee H-factor (in)congruence and ratee feedback reactions. Rater–ratee personality configurations contribute to extraneous variance, affecting their relationship and ratee reactions to performance appraisals. This study highlights how different dyadic personality interactions influence relationship quality and reactions to performance appraisal feedback.

Приведены результаты измерений характеристик турбулентной атмосферы в Саянской солнечной обсерватории (ССО) летом 2023 года. Подтверждено, что причиной появления превалирующего направления возникающих в ССО местных ветров является температурный горно-долинный градиент между горами Саяны, севернее обсерватории ССО, и долиной южнее. Подтвержден меньший регистрируемый уровень средней интенсивности атмосферной турбулентности в ССО по сравнению с турбулентностью над ровной местностью в средних широтах. Подтверждено присутствие на территории ССО когерентной турбулентности, при которой улучшается качество получаемых оптическими приборами изображений.

The results of measurements of the characteristics of the turbulent atmosphere at the Sayan Solar Observatory (SSO) in the summer of 2023 are presented. It is confirmed that the reason for the appearance of the prevailing direction of local winds arising in the SSO is the temperature mountain-valley gradient between the Sayan Mountains, north of the SSO observatory, and the valley to the south. The lower recorded level of the average intensity of atmospheric turbulence in the SSO was confirmed in comparison with turbulence over flat terrain in the middle latitudes. The presence of coherent turbulence in the territory of the SSO has been confirmed, which improves the quality of images obtained by optical devices.

В работе исследуется возможность обнаружения нестабильного радиоактивного изотополога Н2 19О в спектрах поглощения водяного пара в лабораторных условиях. Расчет спектра поглощения H2 19O был выполнен с частотой до 25000 см-1 (400 нм) и до вращательного числа J=20. Вычисления проводились с использованием метода DVR3D. Были проведены оценки параметров контура линии – самоуширение, уширение воздухом и коэффициент температурной зависимости. Найдены спектральные интервалы, перспективные для детектирования Н2 19О в ИК диапазоне.

The paper investigates the possibility of detecting an unstable radioactive isotopologist H219O in the absorption spectra of water vapor in laboratory conditions. The absorption spectrum of H219O was calculated with a frequency of up to 25,000 cm-1 (400 nm) and up to the rotational number J=20. Calculations were performed using the DVR3D method. Estimates of the parameters of the contour of the line were carried out – self-expansion, air broadening and the coefficient of temperature dependence. Spectral intervals promising for detecting H219O in the IR range have been found.

С помощью методики определения типа атмосферной турбулентности (колмогоровской, когерентной) по данным метеоизмерений исследованы возможности определения областей атмосферной турбулентности с заданными характеристиками, на примере интенсивности турбулентности. Структурная характеристика Cn 2 рассчитывается для последовательных перекрывающихся выборок (формируемых скользящим временным окном) из непрерывно пополняемой совокупности значений метеоэлементов. Значения Cn 2 распределяются величине на произвольное количество диапазонов – от условно "слабой" турбулентности до "сильной". Непрерывные последовательности значений Cn 2 одного диапазона соответствуют пространственным областям, в которых интенсивность турбулентности находится в фиксированном интервале. Используя информацию о скорости ветра и времени регистрации, оценены распределения областей турбулентности заданных уровней интенсивности по размерам, направлениям ветров и времени суток.

Using the method of determining the type of atmospheric turbulence (Kolmogorov, coherent) according to meteorological measurements, the possibilities of determining areas of atmospheric turbulence with specified characteristics, using the example of turbulence intensity, are investigated. The structural characteristic of Cn 2 is calculated for successive overlapping samples (formed by a sliding time window) from a continuously replenished set of meteorological element values. The Cn2 values are distributed to an arbitrary number of ranges – from conditionally "weak" turbulence to "strong" turbulence. Continuous sequences of Cn2 values of the same range correspond to spatial regions in which the intensity of turbulence is in a fixed interval. Using information on wind speed and registration time, the distributions of turbulence regions of given intensity levels by size, wind directions and time of day are estimated.

Свойственная для некоторых типов подстилающей поверхности (ПП) анизотропия (снег, пустыня, водная поверхность) вносит коррективы в алгоритмы восстановления на основе данных дистанционного зондирования характеристик облачной и безоблачной атмосферы, а также спектрального и широкополосного альбедо ПП, являющегося одним из ключевых параметров климатической системы. Решение этих задач предполагает проведение численного моделирования спектрально-угловых характеристик полей яркости отраженного и пропущенного солнечного излучения на различных атмосферных уровнях. Представлено сравнение результатов моделирования коэффициентов полусферически-направленного отражения (HDRF) на нижней границе безоблачной молекулярно-аэрозольной атмосферы, выполненных с учетом молекулярного поглощения для ламбертовского приближения и полуэмпирической модели Рамана-Пинти-Верстрате (Rahman-Pinty-Verstrate, RPV).

Anisotropy characteristic of some types of underlying surface (US) (snow, desert, water surface) It makes adjustments to the recovery algorithms based on remote sensing data of the characteristics of the cloudy and cloudless atmosphere, as well as the spectral and broadband albedo of the US, which is one of the key parameters of the climate system. The solution of these problems involves numerical modeling of the spectral and angular characteristics of the brightness fields of reflected and transmitted solar radiation at various atmospheric levels. A comparison is presented of the results of modeling the hemispherically directed reflection coefficients (HDRF) at the lower boundary of a cloudless molecular aerosol atmosphere, performed taking into account molecular absorption for the Lambert approximation and the semi-empirical Rahman-Pinty-Verstrate model (Rahman-Pinty-Verstrate, RPV).

BACKSCATTERING EFFECTS WHEN REFLECTING A SIGNAL FROM A RANDOMLY INHOMOGENEOUS LAYER
Authors: Тинин М.В.
Published: December 2024

Как известно, распространение волн в противоположных направлениях в случайно неоднородной среде приводит к эффектам усиления обратного рассеяния. В частности, волна, проходящая после рассеяния или отражения по тому же пути, что и падающая волна, имеет большее значение дисперсии фазы, чем волна, прошедшая такое же расстояние по прямому пути. При этом возможно так же увеличение средней интенсивности поля. В настоящей работе исследуются эти эффекты при отражении волны от случайно неоднородного слоя.

As is known, the propagation of waves in opposite directions in a randomly inhomogeneous medium leads to the effects of backscattering amplification. In particular, a wave passing after scattering or reflection along the same path as an incident wave has a greater phase dispersion value than a wave traveling the same distance along a straight path. At the same time, it is also possible to increase the average intensity of the field. In this paper, these effects are investigated when a wave is reflected from a randomly inhomogeneous layer.
