Published: January 2025

There is a developing interest in imaginative ways to deal with address the substitution and recuperating of bones and organs in patients experiencing sicknesses like cracks or hip-related illnesses. Hip replacement procedures heavily rely on the choice of implant material, which may not in every case meet necessities due to mechanical and biocompatibility issues, potentially exacerbating inflammation. To conquer these limits, specialists are investigating the utilization of different biomaterials as an option for inserts. Three-dimensional (3D) printing emerges as a promising and efficient manufacturing method for hip replacement applications due to its biocompatibility with the human body. This survey delves into the factors determining hip replacement, examining various production techniques, including direct 3D printing, Melded Affidavit Displaying (FDM), specific Stereolithography (SLA), and Selective Laser Sintering. The concentrate additionally includes surface adjustments of 3D-printed embeds and gives an outline of 3D tissue recovery. This review discusses challenges, issues, also, patterns in 3D printing for inserts, drawing conclusions and presenting limitations and challenges. The gathered information underscores the significant potential of 3D printing in facilitating affordable hip replacement solutions. The research spans key domains, including mining, minerals, metallurgy, and the bio-polymer composite industry, addressing scientific and technical challenges pertinent to the metallurgy of polymer matrix composites.

The modern urbanization and advanced lifestyle are always at a greater danger of consuming energy. Unfortunately, there are significant problems with conventional fossil fuel energy sources, including a lack of storage, high costs, and hazardous contamination. Instead, solar energy is an affordable, sustainable, and sustainable choice for the coming energy requirement on the global market. Among photovoltaic technologies, organic photovoltaics (OPVs) show a low-cost, adaptable, environmentally friendly, and simple-to-process method of converting solar energy into electricity. However, due to their limited lifespan and the energy-intensive deposition of the top metal electrode, OPVs with a standard device configuration are still a long way from being industrialized. To enhance the stability, cost issues and easy fabrication process, an inverted device architecture is widely preferred model. Polymers doped with metals leads to improved charge transport, plasmonic effects, stability enhancement, optical properties, and functionality by exploiting the unique properties of metals. Ongoing research in this area aims to further optimize metal-doped polymer solar cells for commercial applications in renewable energy. This review summarizes and illustrates recent developments in device architectures, operating principles, functionalities, and advancements at each component layer, as well as how these developments relate to the effectiveness of OPVs. Author tries to accentuate the various research practices and methods opted by scholars to stimulate the efficiency of organic solar cell which will provide a broad idea for chemist to develop new synthetic monomers and strategies to enhance the photovoltaic applications.

Authors: Ayesha Mohammed , Mallikarjuna B.
Published: January 2025

We aim to study, the linear stability analyses of Rayleigh-Bénard convection in a horizontal layer of ternary hybrid nanofluids. The difficulties concerning the two nano fluid yielded eigen values, which were subsequently obtained and compared. Models of the thermophysical characteristics of nano liquids have been developed based on the characteristics of water as the base liquid and the nanoparticles of aluminum oxide, zirconium oxide, and magnesium oxide. An analytical solution is found for the stationary basic solution of the vertical throughflow. It turns out that the fundamental fields of temperature and velocity are independent of the Newtonian. An examination of linear stability is performed, which results in an eigenvalue problem with order four. The neutral stability curves and the critical Rayleigh number for the onset of instability are obtained by applying a numerical solution to the eigenvalue problem. A strong agreement is discovered when the water results are compared to the findings of earlier studies as a limiting case. A graphic is used to represent the outcomes. The neutral stability curve’s location and the critical Rayleigh number are affected by these factors. The different cases of mono, hybrid, and ternary nanofluids are discussed in detail.

We investigate the synergistic consequences of Ohmic heating and viscous degradation on unsteady MHD flow across an extensible sheet immersed in fluid with pores. For the various assumptions on the real problem, a physical model led us to a non-linear coupled partial differential equation which is then transformed to ordinary differential equation using similarity technique. The computational work is carried out using shooting technique compresses of Runge-Kutta-Felhberg method with Newton-Raphson iterative scheme to solve the non-linear coupled ordinary differential equations with converting a boundary value problem to initial value problem by choosing a guess value. A study is conducted on governing parameters, including the Biot number, Weissenberg number, Eckert number, Joule consequences, unsteadiness, and Forchheimer number. Graphics are used to show how these characteristics affect concentration, velocity, and temperature.

Published: January 2025

Today, CNG refueling stations are expanding worldwide to provide vehicles with CNG as fuel. However, constructing CNG stations in urban areas has led to serious threats to public and property safety. Therefore, risk assessment in these locations is essential. In most cases, risk assessment is the most complex part of risk management. While static methods, such as the Bow-tie approach, pose major limitations to most conventional risk assessment methods, dynamic risk assessment offers a better picture of risks and their consequences. This study aimed to develop a dynamic and comprehensive quantitative risk analysis (DSQRA) approach to evaluate accident scenarios and model risks in CNG stations. In this approach, FMEA was used for hazard analysis, while a Bow-tie diagram and Bayesian network were employed to model the worst-case accident scenario and assess risks. According to the results, dispenser gas leakage was identified as the worst-case accident scenario, with hose cracking and corrosion being the most critical factor. Therefore, in the risk management of CNG stations, priority should be given to the most probable basic events and main contributing factors identified in this study to reduce the likelihood of accident scenarios and thus mitigate risks.

Authors: Bańczyk Emilia
Published: January 2025

The author analyzes mothers’ statements in selected Facebook discussion groups to investigate the categories WE and THEY in the mothers’ discourse on the Internet. The aim of the article is to analyze the collective identity of mothers – how they perceive themselves, how they perceive their social environment, who belongs to the mothers’ close and distant social context, and when THEY become hostile. The data analyzed, primarily includes texts in which the personal pronouns referring to the semantic categories WE and THEY (my ‘we’, nas ‘us’, oni ‘they’, ich ‘them’) appear. The analysis of the data from the two discussion groups has shown that there is no single distinct discourse of mothers but multiple discourses in which various factors, such as the group characteristics and the members’ interests, have an impact on their worldview and child rearing.

Authors: Oliveira Lamonise Vasconcelos , Villa Simone Barbosa
Published: January 2025

Impacts on the built environment increase user vulnerability and impair their adaptive capacity. Identifying the main impacts in the context of Social Housing (SH) and residents’ perceptions can be used to establish priorities for action to promote better living conditions. These actions have never been more relevant given the urgency imposed by the COVID-19 pandemic. Therefore, this article is part of a master's research dissertation entitled "Assessing the impacts of Covid-19 on social housing and its adaptations to a more resilient built environment". This article addresses the main results of the bibliographic research that forms the theoretical foundation and the empirical research, whose objects of analysis are two SH complexes, in the city of Uberlândia, Minas Gerais, Brazil. Through observation in a case study, the research is based on quantitative-qualitative post-occupation evaluation (POE) methods for data collection and analysis. The results show that small and insufficient living spaces and the need for constant renovations and repairs generate dissatisfaction among residents. Furthermore, incorporating new activities into the SH units required renovation and adaptations. These factors increase the risk of contamination, highlighting the importance of resilient built environments. Many of these have led to problems such as insufficient humidity, insolation and natural ventilation, which increase susceptibility to contamination. This context reinforces the importance of resilient built environments.
Capital financiero versus capital industrial: un impacto peligroso. (Sobre la degeneración del capital industrial)
Authors: Valenzuela Feijóo José
Published: January 2025

Uno de los rasgos distintivos de la fase monopólica del capitalismo es la pugna cada vez mayor entre dos fracciones de la clase dominante: el capital industrial y el capital financiero. En este artículo se analiza cómo la hegemonía del segundo ha desplazado el papel dirigente y transformador del primero, en un proceso de subordinación y deformación de la lógica productiva de la valorización de capital en favor de la especulativa. A esto se le llama “degeneración del capital industrial”. Mediante el caso de los Estados Unidos y la crisis de 2008, se muestra que la especulación ha superado ya a la inversión productiva, así como las consecuencias negativas que esto ha tenido para la estabilidad y el crecimiento económico. El parasitismo y la decadencia extrema, que se expresan en la profundización de la desigualdad, la creciente dependencia de actividades improductivas y el debilitamiento de las capacidades productivas del capitalismo, sugieren que el sistema entra en una fase de descomposición, que puede ser terminal.

Authors: Carazas-Vera María Soledad
Published: January 2025

La depresión es un problema de salud pública que ocasiona discapacidad y disminución significativa de la calidad de vida. Múltiples estudios señalan la efectividad de la psicoeducación como parte del tratamiento. Objetivo: Determinar la relación entre la psicoeducación estructurada y el nivel de adherencia al tratamiento en pacientes adultos atendidos en el Instituto Nacional de Salud Mental Honorio Delgado-Hideyo Noguchi (INSM HD-HN). Materiales y métodos: Estudio observacional, analítico, retrospectivo y transversal. Se revisaron las historias clínicas de 536 pacientes adultos con diagnóstico de trastorno depresivo (TD) y se incluyeron a 268 que habían recibido psicoeducación y a 268 que no lo recibieron. Resultados: Se puso en evidencia una asociación significativa entre psicoeducación estructurada y adherencia al tratamiento (x2 = 125,26; p = 0,000), y se encontró, igualmente, asociación entre el abandono del tratamiento y el no haber recibido psicoeducación estructurada (x2 = 10,12; p = 0,001). Un 40,1 % de pacientes con TD se adhirieron al tratamiento; 57,6 % de ellos asistieron regularmente a sus citas médicas; el 72 % abandonó el tratamiento durante el período de seguimiento; y un 40,3 % se adhirió a la psicoeducación. La edad (x2 = 22,59; p = 0,000), el estado civil (x2 = 15,45; p = 0,009), la ocupación (x2 = 15,29; p = 0,000) y la comorbilidad (x2 = 12,406; p = 0,006) estuvieron también asociados a la adherencia al tratamiento. Conclusiones: El nivel de adherencia al tratamiento es bajo en la muestra estudiada y repercute en un alto grado de deserciones durante el período de seguimiento. Una psicoeducación estructurada y de naturaleza individual predominante es un factor importante en el logro de mayor adherencia y menor abandono del tratamiento en pacientes deprimidos. Dentro de las variables relacionadas a una mayor adherencia, se toman en cuenta la edad mayor a 60 años, el estado civil casado, la dedicación a labores del hogar y la presencia de una comorbilidad física.

Authors: Carpio Franco , Torres Dora , Salguero Carolina , Lindo Renzo , Ruiz-Grosso Paulo
Published: January 2025

Tuberculosis (TB) remains a significant global health burden, with substance abuse being a common comorbidity. Cocaine-derived drugs, particularly crack and cocaine hydrochloride, have been associated with poor TB treatment outcomes. Objective: This systematic review aimed to synthesize the evidence on the relationship between crack or cocaine hydrochloride use and TB treatment outcomes. Materials and methods: A comprehensive search was conducted across multiple databases (PubMed, Ovid, EBSCOhost, Lilacs, and Google Scholar) using structured search terms. Eligible studies were included in a meta-analysis performed using STATA 16. Results: Five studies were included in the analysis. Overall, crack or cocaine use was associated with a higher risk of loss to follow-up or non-completion of TB treatment (OR = 2.73; 95% CI: 1.33-5.61). In the subgroup of individuals with active TB, this association was particularly strong for loss to follow-up (OR = 7.029; 95% CI: 2.66-18.57). However, no significant association was observed between crack or cocaine use and treatment non-completion in the latent TB subgroup (OR = 1.26; 95% CI: 0.77-2.05). Conclusions: Consumption of crack or cocaine is associated with adverse TB treatment outcomes, particularly loss to follow-up among individuals with active TB. These findings highlight the importance of addressing substance abuse as part of comprehensive TB control strategies.

Published: January 2025

Conditional Value at Risk (CVaR) is known as a risk measurement tool to estimate losses in investing. Financial data tends not to be normally distributed so that the flexible Copula method can be used to analyze financial data without requiring the assumption of normality. This study aims to analyze the CVaR of a stock portfolio with Clayton's Copula. The study began with collecting daily stock closing price data for the period October 3, 2022 to November 3, 2023. After the data was collected, the return value of the closing stock price was calculated. Furthermore, autocorrelation and heteroscedasticity tests were carried out on the closing stock price return data. Then, the Kendall's Tau correlation was calculated to obtain the Clayton Copula parameters. After that, the stock weights in the portfolio were calculated using the Mean Variance Efficient Portfolio (MVEP) method and new return data was generated using the Clayton Copula parameters. Furthermore, the portfolio return was calculated to obtain the VaR value of the formed portfolio. Then, it was repeated by generating data up to the VaR calculation 1000 times to obtain the average value of the portfolio VaR. Then, the same thing was done to CVaR. The results of the CVaR analysis of the stock portfolio with Copula Clayton on the two stocks, namely PT Aneka Tambang Tbk (ANTM) and PT Timah Tbk (TINS), obtained losses of 3.04%, 3.56%, and 4.57% with a confidence level of 90%, 95%, and 99%. This value indicates the percentage of investment risk that may be obtained in the next one-day period. This shows that the higher the level of confidence, the greater the CVaR value will be.

Published: January 2025

This article examines second language learning ability by analyzing second language development. It also examines the age factor in learning a language other than the mother tongue and attempts to clarify whether there is currently sufficient evidence to show that young people undergo real changes in their language skills.. Research such as inspiration for the learning climate, as well as exposure and behavior in the language will also be addressed and data analyzed to assess if they play an essential role in encouraging students to achieve effective second language skills. It was widely known to create a big improvement in language learning when you are young to study a second language. However, the findings show that this is not completely applicable in all situations, provided that other considerations such as language sensitivity and enthusiasm influence the effective accomplishment of second-language learning. If vocabulary is lacking, therefore this could discourage students from studying the language effectively. However, it is worth noting that factors such as motivation and exposure play a more important role in the learning stage than the aging factor. This empowers the learner because, regardless of his age, it is extremely important for him to be motivated enough and have enough language exposure from the beginning.
Highlights:

Analyzes second language development and age factor in language learning.
Highlights motivation, exposure, and behavior's impact on effective language skills.
Motivation and exposure outweigh age in successful second-language acquisition.

Published: January 2025

Antecedente: Existen estudios previos sobre la asociación entre estrés y trastornos de la conducta alimentaria (TCA) que incluían estudiantes universitarios y de medicina. Sin embargo, no se conocen estudios de estrés académico asociado a TCA específicamente en el contexto del externado médico. Objetivo: Determinar la asociación entre estrés académico y probable TCA en estudiantes de medicina que cursan el externado de una universidad de Perú en el 2022. Métodos: Estudio transversal que incluyó a estudiantes de medicina que cursaban el externado médico durante el ciclo académico 2022-I de una universidad privada en Lima, Perú y que hayan asistido al menos una semana a su sede hospitalaria de externado. Se evaluó un probable TCA y estrés académico con los cuestionarios Eating Attitudes Test-26 y el Inventario SISCO, respectivamente. Se realizó un análisis de regresión de Poisson con varianzas robustas para calcular las razones de prevalencia (RP) e intervalos de confianza al 95% (IC95%) que miden el efecto del estrés académico severo y moderado para el probable TCA, en comparación con el estrés académico leve, ajustado por variables confusoras. Además, se realizó una evaluación de la interacción de la asociación con la variable sexo. Resultados: Se incluyó a 193 participantes, la mayoría mujeres (59.1%) con mediana de 21 años. 43.0% había desaprobado una materia y 18.7% tenía un diagnóstico previo de salud mental. Un nivel de estrés académico moderado (RPa: 2.50; IC95%: 1.25 a 5.00) y severo (RPa: 4.40; IC95%: 2.32 a 8.37) se asociaron a una mayor proporción de tener probable TCA en comparación de aquellos con un nivel de estrés académico leve. El sexo no fue una variable modificadora de efecto para la asociación. Conclusión: Tener un nivel de estrés académico moderado o severo se asoció a una mayor frecuencia de tener probable TCA en un grupo de estudiantes...
