Conhecer o corpo humano e seu funcionamento faz parte do processo educacional básico. A inexistência de peças anatômicas em escolas para abordagem do conteúdo programático pode representar um fator limitador do processo de aprendizagem. Essa situação, pode muitas vezes, ser contornada por instituições de ensino que, através de projetos, venham a ter um papel fundamental na melhoria da qualidade do ensino, aproximando o escolar dos laboratórios anatômicos. Este estudo tem como objetivo relatar a experiência de estudantes de medicina integrantes da Liga Acadêmica de Anatomia no projeto “Anatomia nas Escolas”. O projeto foi realizado em um colégio estadual, em Vassouras-RJ, no ano de 2023, e o público-alvo foram alunos do 8⁰ ano. Os temas abordados relacionaram-se aos sistemas: reprodutor, endócrino e urinário, seus principais órgãos, suas funções, principais Infecções Sexualmente Transmissíveis (IST´s), formas de prevenção e recursos para contracepção. A metodologia consistiu na aplicação de um pré-teste e um pós-teste com o intuito de analisar o desempenho dos alunos, que conseguiram associar o conteúdo com a prática, por meio de demonstração em peças sintéticas. Concluiu-se que o projeto se constituiu em instrumento efetivo para a educação em saúde e otimizador da abordagem de conteúdos programáticos da Base Nacional Comum Curricular.

Published: December 2024

Abstract. This study presents aerosol iron isotopic compositions (δ56Fe) in Western and Central Equatorial and Tropical Pacific Ocean. Aerosols supply iron (Fe), a critical element for marine primary production, to the open ocean. Particulate aerosols, > 1 µm, were sampled during EUCFe cruise (RV Kilo Moana, PI: J. W. Murray, 2006). One aerosol sample was isotopically lighter than the crust (δ56Fe=-0.16 ± 0.07 ‰, 95 % confidence interval), possibly originating from combustion processes. The nine other aerosol samples were isotopically heavier than the crust, with a rather homogeneous signature of 0.31 ± 0.21 ‰ (2SD, n=9). Given i) this homogeneity compared to the diversity of their modeled geographic origin and ii) the values of the Fe/Ti ratios used as a lithogenic tracer, we suggest that these heavy δ56Fe signatures reflect isotopic fractionation of crustal aerosols caused by atmospheric processes. Using a fractionation factor of Δsolution - particle=-1.1 ‰, a partial dissolution of ≈20 % of the initial aerosol iron content, followed by the removal of this dissolved fraction, would explain the observed slightly heavy Fe isotope signatures. Such fractionation has been observed previously in laboratory experiments, but never before in a natural environment. The removal of the dissolved fraction of the aerosols has not been previously documented either. This work illustrates the strong constrains provided by the use of iron isotopes for atmospheric process studies.

Приводятся результаты применения различных методов обогащения к бедным гематитовым рудам. Исходная руда представляла собой глинистую породу с содержанием железа 17,2%. Приведен минералогический состав исходной руды, результаты обогащения отсадкой, магнитной сепарацией, в том числе после обжига с добавками, флотацией. Показано, что обогащение самым простым методом отсадки позволяет достичь содержания железа общего в концентрате 50%, но на этот показатель определяющее влияние оказывает крупность вкрапления гематита в руде. Дальнейшее обогащение позволяет достичь содержания железа общего в концентрате 60%.
The results of applying various methods of processing to low-grade hematite ores are presented. The original ore was a clay rock with an iron content of 17,2%. The mineralogical composition of the original ore, the results of processing by washing, magnetic separation, including after roasting with additives, flotation are given. It is shown that enrichment by the simplest method of cleaning allows reaching the iron content of 50%, but this indicator is determined by the size of hematite inclusions in the ore. Further enrichment makes it possible to achieve iron content of 60%.

Authors: Grigoryants A. A. , Akseneko V. A. 
Published: December 2024

Introduction. One of the less common forms of adenomyosis is the nodular type, characterized by localized foci composed of damaged endometrial glands and altered muscle and connective tissue ﬁbers. Diagnosing nodular adenomyosis is oﬅen challenging, with the diagnosis frequently made intraoperatively or during histological examination.The purpose of the work. To analyze a clinical case involving a patient with nodular adenomyosis and a prolonged history of pelvic pain syndrome, aiming to identify diagnostic errors associated with this condition.Materials and methods. A clinical case was reviewed based on the patient’s medical history and treatments conducted prior to admission to the Gynecology Department of the Stavropol State Medical University Medical Center.Results and discussion. The chronology of diagnosis and treatment, along with an analysis of errors that led to the chronicity of the pathological process and subsequent deterioration in the patient’s quality of life and overall condition, is presented. This clinical case demonstrated that a gynecologist’s primary responsibility when examining patients with pelvic pain syndrome is to conduct detailed diagnostics. The authors re-evaluated the patient’s magnetic resonance imaging scans and suspected the diagnosis of “nodular adenomyosis”, which justiﬁed performing laparoscopy to conﬁrm the condition. During the procedure, the diagnosis was conﬁrmed, and the nodular adenomyosis was excised simultaneously. To prevent adhesion formation, an anti-adhesion barrier was applied.Conclusion. Laparoscopy is one of the most critical methods for diagnosing pelvic pain syndrome, as it enables early diagnosis, detailed examination of pelvic and abdominal organs, and the simultaneous execution of therapeutic interventions.

The study investigated sexual behaviours and reproductive health issues among students in tertiary institutions in Delta State, and discussed their counselling implications. It addressed some relationship issues that confront students at the tertiary education level which include awareness about prventive measures against sexually transmitted infections among sexually active students; young girls resorting to unsafe abortion; high level of sexual abuse and rape; and some female students engaging in part-time prostitution, among others. The study's population consisted of 14,650 first-year students in higher educational institutions in Delta State of Nigeria. Based on willingness to participate, a purposeful sampling technique was used to select a sample size of 3,490 students. A questionnaire on Sexual Behaviour and Reproductive Health Issues (SEBARHI) was developed by the authors and used to collect data on Sexual Behaviour and Reproductive Issues among the students. Data collected was analyzed with descriptive statistics and it was found that a considerable number of undergraduates in the area of study engage in risky sexual behaviour and also demonstrated ignorance of safe reproductive health practices. More female students reported indulging in homosexuality, bisexuality, anal sex, masturbation and threesome sex, amongst others. The counselling implications of the findings of the study were discussed for increasing appropriate awareness of the consequences of risky sexual behaviours, unsafe reproductive health practices and need to seek help from professional counselling practitioners.
Human–Machine Relations Composed, Decomposed, Recomposed
Authors: Hedayati Mona 
Published: December 2024

Abstract
This article delves into the intricate and evolving dynamics of human–machine relations, pushing for a reconceptualization of agency as a mutable and distributed phenomenon rather than a static attribute. It traverses a multitude of theoretical perspectives across disciplines each contributing to a nuanced understanding of the intertwined existences of humans and machines. These theoretical excursions reveal a complex landscape where agency is not merely a property of beings but arises within the entanglements of actions and interactions, suggesting a deeply interconnected fabric of existence that defies simple categorization. By engaging with the material and immaterial elements on a micro and meso scale of analysis, the article looks into practical manifestations of these theories, including human–computer interaction and the agential capacities of software and algorithms within themselves. These reflections highlight the constant negotiation of agencies within a shared operational space, emphasizing the importance of recognizing the distributed nature of agency in shaping human–machine relations. In a shift in perspective to macro scale in the final section, the article demands a new understanding of human-centered accountability within this reorientation of human–machine relations.

Authors: Flores Alvarado María , Gallyas Ortiz Valentina , García Obreque Daniela , González Matamala María 
Published: December 2024

Introducción: La enfermedad poliquística hepática (EPH) es una enfermedad benigna de herencia autosómica dominante. Su prevalencia es de 0.13-0.6%, presentándose síntomas compresivos en 2-5% de los pacientes.
Caso Clínico: Paciente femenino, 51 años, sin antecedentes de relevancia, desde hace 2 años con saciedad precoz, disminución de peso (24%), disnea de mínimos y moderados esfuerzos. Masa epigástrica palpable. Es intervenida por enfermedad ginecológica vía laparoscópica, donde se pesquisa quiste hepático de gran tamaño.
Tomografía computada (TC) de abdomen y pelvis evidenció múltiples quistes derechos de hasta 19 cm de diámetro provocando efecto de masa.
Se realiza fenestración quística con hepatectomía segmentaria laparoscópica con stappler en segmentos V, VI, VII, VIII. Evolución post-operatoria favorable.
Estudio quistes: Gram y cultivos negativos, citológico quistes biliares simples sin células neoplásicas. Serología hidatidosis negativa.
Discusión: En mayores de 40 años se diagnostica EPH con 4 o más quistes hepáticos, sin quistes en otros órganos. Las complicaciones (hemorragia, rotura e infección) son infrecuentes (5%), por lo que solo se intervienen pacientes sintomáticos.
Se recomienda anticipar la reserva hepática con TC/Resonancia magnética (RM) y resección hepática con fenestración quística si esta es mayor o igual a un segmento hepático. La formación y crecimiento quístico es similar antes y después de la cirugía. El trasplante hepático es el único tratamiento curativo y se reserva para aquellos sin reserva hepática o pacientes con síntomas severos refractarios.
Parametric assessment of window orientation, glazing types, and window-to-wall ratio on energy consumption in individual housing: the case of Guelma, Algeria
Authors: Hadef Selma Saci , Khelil Sara , Alkama Djamel 
Published: December 2024

The building envelope, through its components, affects the thermal performance and energy consumption, mainly through windows, which provide easy access for heat gain or loss. In this context, Windows play an essential role in building energy efficiency, influencing heating and cooling requirements. Three key window parameters must be optimized at the design stage to take advantage of solar gain while limiting overheating: orientation, glazing type, and window-to-wall ratio. Therefore, this article aims to assess the impact of different window parameters on the energy used for heating and cooling of an individual housing in Guelma, located in the north-east of Algeria. Four orientations, three glazing types, and ten window-wall ratio scenarios were studied based on a parametric simulation using Rhinoceros 3D and its Grasshopper plug-in. The research results showed that the window to the north has the highest overall energy use while the window to the south has the lowest. Also, the rise in the window/wall ratio and the increase in energy usage are therefore positively correlated. Moreover, double glazing low-emissivity was found to be the most effective in terms of energy savings across all orientations. These savings were especially notable for high window/wall ratios, with the southern orientation reaching up to 35.21%, the western orientation, 25.13%, the eastern orientation 27.05%, and the northern orientation 23.24%. . This study provides guidelines for window design to reduce energy use, maximize thermal comfort, and enhance the energy efficiency of buildings.

Published: December 2024

Cadmium sulfide (CdS) thin films were synthesized on glass substrates using the chemical bath deposition (CBD) technique to investigate the effects of varying thiourea concentrations on their structural and optical properties. X-ray diffraction (XRD) analysis confirmed a cubic zinc blende structure, with decreasing crystallinity and grain sizes, which reduced from 55.67 nm to 11.34 nm, as thiourea concentration increased. The micro strain and dislocation density showed an increasing trend, with micro strain rising from to and dislocation density increasing from lines/m² to lines/m², indicating a deterioration in crystalline quality and increased lattice imperfections at higher thiourea concentrations. These structural changes influenced film morphology, reducing grain connectivity and increasing surface disorder. Optical analyses revealed a blue shift in the transmission spectra, higher transmittance, and a band gap widening from 1.80 eV to 1.96 eV, with Urbach energy rising from 0.2 eV to 0.5 eV. The refractive index has been found to decrease with increasing thiourea content. These findings demonstrate that thiourea concentration significantly affects both the structural integrity and optical properties of CdS thin films, highlighting their potential for tailored optoelectronic applications.
Diagnosis of bearing faults using an advanced feature extraction based on WPT and EEV methods

Published: December 2024

Detecting faults in rolling-element bearings can be achieved by monitoring and analyzing various signals such as vibration signal, acoustic noise, and stator current. Frequency spectral analysis using signal processing technique is one of many methods which has been used in fault diagnosis in this field. Other techniques as FFT, MUSIC, ESPRIT, STFT, and DWT are used to detect electrical or mechanical faults in induction motors (IMs). Motor current signature analysis using FFT tool (MCSA-FFT) is the most commonly utilized method. However, it has significant drawbacks, including resolution issues and the limitation of being unsuitable for analyzing non-stationary signals. To address these limitations, a method for analyzing stator current based on the Wavelet Packet Transform (WPT) technique is proposed for detecting this mechanical faults (rolling element bearing faults). The stator current signal is decomposed into nine levels using the Wavelet Packet Decomposition (WPD) method. Subsequently, EEV estimation is applied to the resulting coefficients to identify bearing faults. To confirm the effectiveness of the proposed technique, we examine the performance of a healthy and faulty motor under both no-load and full-load conditions. The findings indicate that the proposed method is more effective and efficient than traditional approaches.

Published: December 2024

In this paper the fire behaviour of composite columns in hollow square and circular sections infilled with concrete was studied by the method of calculation of the EC4 wich is a summation method that uses equations to determine the temperature field and residual strength of composite hollow sections subjected to a conventional fire, and then a comparison was made between residual resistances calculated by this method and those calculated by a formula from the literature. Calculations have shown that the fire resistance of the columns is very sensitive to the variation of the transverse dimension of the profile and the thickness of the tube. As for the comparison between the fire resistances of square profiles and those of circular sections, it is noted that whatever the area of the section, the resistance of circular profiles is greater than that of square profiles especially during the first hour of fire, and this is because of the large circumference of the square sections compared to the circular ones. And finally the index of residual resistance calculated by Eurocode 4 (IRREC4) remains lower than that calculated by the literature formula (IRRHan) up to certain values of the section dimension and the buckling length beyond which it will be the opposite.

Published: December 2024

This research examines the use and significance of metaphors in the lyrics of James Arthur's songs. The research aims to identify and categorize the types of metaphors used and to interpret their meanings within the context of the songs. This research was designed in qualitative research. The study categorizes metaphors into three types: structural, orientational, and ontological. Based on research findings, the researcher found that ontological metaphors are the most frequently used, followed by structural and orientational metaphors. By exploring the metaphors in selected songs, the research found how metaphors convey complex emotional experiences and articulate themes of love, memory, safety, and loss. The technique of descriptive analysis was applied to analyze data by reading the data and identify the types of metaphor used in James Arthur's selected song lyrics. Data collection is conducted through document study and non-participatory observation. Primary data is derived from the song lyrics, while secondary data is gathered from related journals and resources. These results are expected to help English teachers to use metaphors in the teaching process, and using metaphors in class can be an effective way to expand students' vocabulary, besides that it can be material for consideration and support for future researchers.
Critical temperature of YxGd1-xBa2Cu3Oy solid solutions
Authors: Biasi Ronaldo Sergio de , Fernandes Antonio Alberto Ribeiro 
Published: December 2024

The magnetic modulated microwave absorption (MAMMA) technique has become a powerful method to investigate the behavior of ceramic superconductors. In this work, it was used to measure the superconducting transition temperature of YxGd1-xBa2Cu3Oy solid solutions in a conventional X-band electron paramagnetic resonance spectrometer. The experimental results show that the critical temperature goes through a maximum at x = 0.4. This is consistent with the fact that the critical temperature in ceramic copper-based superconductors tends to increase with the number of copper-oxygen layers per unit cell and may provide new clues on how to increase the critical temperature of ceramic superconductors.
