Published: January 2025

Radiofrequency ablation (RFA) is a minimally invasive procedure that utilizes localized heat to treat tumors by inducing localized tissue thermal damage. The present study aimed to evaluate the temperature evolution and spatial distribution, ablation size, and reproducibility of ablation zones in ex vivo liver, kidney, and lung using a commercial device, i.e., Dophi™ R150E RFA system (Surgnova, Beijing, China), and to compare the results with the manufacturer’s specifications. Optical fibers embedding arrays of fiber Bragg grating (FBG) sensors, characterized by 0.1 °C accuracy and 1.2 mm spatial resolution, were employed for thermometry during the procedures. Experiments were conducted for all the organs in two different configurations: single-electrode (200 W for 12 min) and double-electrode (200 W for 9 min). Results demonstrated consistent and reproducible ablation zones across all organ types, with variations in temperature distribution and ablation size influenced by tissue characteristics and RFA settings. Higher temperatures were achieved in the liver; conversely, the lung exhibited the smallest ablation zone and the lowest maximum temperatures. The study found that using two electrodes for 9 min produced larger, more rounded ablation areas compared to a single electrode for 12 min. Our findings support the efficacy of the RFA system and highlight the need for tailored RFA parameters based on organ type and tumor properties. This research provides insights into the characterization of RFA systems for optimizing RFA techniques and underscores the importance of accurate thermometry and precise procedural planning to enhance clinical outcomes.

Authors: Erss Maria , Loogma Krista
Published: January 2025

In light of the fact that an increasing number of upper secondary school students in Estonia work in parallel with attending school or during school holidays, the purpose of the study was to ascertain whether work experience and the competencies acquired through work are, in combination with other school-related (teacher agency support), personal (resilience, achievement in Estonian language, mathematics and history) and socio-demographic (gender and mother tongue) factors, related to student agency in school. The second aim was to broaden the understanding of what students learn at work. The study used a mixed-methods approach involving a survey of upper secondary students (aged 16–19, N = 3179) in 30 schools followed by qualitative interviews with 18–19-year-old students who have gained work experience (N = 13). The analysis comprises a hierarchical linear regression analysis (N = 1947) and a thematic analysis of the interviews. The results indicate that work experience, perseverance, teacher agency support, male gender and Estonian mother tongue are positively related to agency while various skills learned at work had no relationship and student achievement in history was only relevant before work experience was added to the model. The interviews showed that students develop skills related to, e.g., self-regulation, self-awareness, career-awareness, social skills and self-confidence through work.

Published: January 2025

Under the continuous innovation and widespread application of digital technology, accelerating the formation of new-quality productive forces is an unavoidable theme of the times. Based on a systematic analysis of the logical relationships between the digital economy, industry–academia–research collaborative innovation, and new-quality productive forces, this article constructs a theoretical analysis framework for the impact of the digital economy on new-quality productive forces. This article also employs spatial econometric techniques and panel threshold models to empirically test the relationships among the three. This study finds that spatial correlation is a significant factor that cannot be ignored in the process of the digital economy and industry–academia–research collaborative innovation empowering the formation of new-quality productive forces. The empowering effects of the digital economy and industry–academia–research collaborative innovation on new-quality productive forces differ, with the former’s effect significantly higher than the latter. The combined effect of both shows a strong synergistic impact on accelerating the formation of new-quality productive forces. Further threshold model tests reveal that both the digital economy and industry–academia–research collaborative innovation have certain thresholds in promoting the development of new productive forces. Only when they achieve synergy and progress together can they maximize their respective roles in driving the development of new productive forces. This research is of great significance for fully leveraging the digital economy to empower the formation of new-quality productive forces, thereby promoting high-quality economic development in China.

Published: January 2025

Biogas is a renewable energy source that can be locally produced from the anaerobic digestion of several organic wastes, serving as a partial substitute for natural gas derived from non-renewable sources. This work provides an overview of feedstock used for biogas production, anaerobic digestion process, biogas usage, and global and Brazilian biogas generation. In addition, the potential output in Paraná State, Brazil was evaluated. In Brazil, the full potential of biogas, especially within the agricultural sector, has not been explored. Paraná, one of Brazil’s leading agricultural producers, has emerged as a prominent biogas producer, particularly from landfill and industrial sources, primarily for electricity generation. According to the findings of this work, the biogas produced from pig, chicken, and confined cattle waste could generate 2.23 TWh of electricity, equivalent to approximately 8% of the state’s energy consumption. Moreover, the biomethane potential surpasses the 2021 production by 3.4 times. Based on the overview and results, the biogas produced in Paraná can significantly contribute to sustainable energy generation, which would reduce greenhouse gas emissions and promote a cleaner and more environmentally friendly energy matrix.

Authors: Feng Yuchen , Xu Runguo
Published: January 2025

Sustainable development, a key global priority, is increasingly shaped by factors such as the sharing economy, environmental patents, and energy efficiency, which have significant social, economic, and environmental implications. With rising public concern about the environment, volatile energy prices, and growing market pressure, more businesses are seeking ways to optimize energy usage. The purpose of this study is to explore the impact of green technologies, the sharing economy, and energy efficiency on environmental sustainability in the G7 countries. By utilizing quarterly data from 2014Q1 to 2020Q4, this study measures ecological sustainability using the load capacity factor. The research employs the Moments Quantile Regression (MMQR) approach to assess the relationships between variables, while the Cross-Sectionally Augmented IPS (CIPS) test is used to examine unit roots in the data. The objective of this study is to evaluate how these factors contribute to environmental sustainability and to provide policy recommendations for enhancing sustainability practices across the G7 countries. The scientific novelty of this work lies in its application of MMQR to understand the varying effects of energy efficiency, the sharing economy, and green technologies on sustainability and its incorporation of short-term quarterly data, offering fresh insights into the dynamics of these relationships. The findings reveal that an increasing number of sharing economy users and population growth positively impact environmental sustainability. Moreover, policies promoting efficient resource utilization and the sharing economy can significantly enhance sustainability. However, urbanization and industrialization pose challenges, necessitating more stringent industrial regulations and careful urban planning. The results indicate that while energy efficiency and the sharing economy hold theoretical potential for sustainability, their practical impacts can vary. To ensure long-term sustainability, the adoption of environmental patents and green technologies is critical, with initial investments yielding substantial returns as these technologies become more widely adopted. This study proposes policy recommendations including greater international collaboration, comprehensive energy policies, advanced urban planning, expanded support for green innovation, and stricter industrial regulations. The research also underscores the role of the United States in leading global sustainable development initiatives. Finally, this study suggests that future research should consider longer timeframes, advanced analytical methods, and a broader range of variables to further understand the complexities of sustainable development.

Published: January 2025

The demand for clean-cut seafood fillets has led to an increase in fish processing side streams, which are often considered to be low-value waste despite their potential as a source of high-quality proteins. Valorizing these side streams through innovative methods could significantly enhance global food security, reduce environmental impacts, and support circular economy principles. This study evaluates the environmental sustainability of protein recovery from herring, salmon, and cod side streams using pH-shift technology, a method that uses acid or alkaline solubilization followed by isoelectric precipitation to determine its viability as a sustainable alternative to conventional enzymatic hydrolysis. Through a Life Cycle Assessment (LCA), five key environmental impact categories were analyzed: carbon footprint, acidification, freshwater eutrophication, water use, and cumulative energy demand, based on a functional unit of 1 kg of the protein ingredient (80% moisture). The results indicate that sodium hydroxide (NaOH) use is the dominant environmental impact driver across the categories, while energy sourcing also significantly affects outcomes. Compared to conventional fish protein hydrolysate (FPH) production, pH-shift technology achieves substantial reductions in carbon footprint, acidification, and water use, exceeding 95%, highlighting its potential for lower environmental impacts. The sensitivity analyses revealed that renewable energy integration could further enhance sustainability. Conducted at a pilot scale, this study provides crucial insights into optimizing fish side stream processing through pH-shift technology, marking a step toward more sustainable seafood production and reinforcing the value of renewable energy and chemical efficiency in reducing environmental impacts. Future work should address scaling up, valorizing residual fractions, and expanding comparisons with alternative technologies to enhance sustainability and circularity.

Published: January 2025

In April 2023, a major dust storm event in Lanzhou attracted widespread attention. This study provides a comprehensive analysis of the causes, progression, and dust sources of this event using multiple data sources and methods. Backward trajectory analysis using the HYSPLIT model was employed to trace the origins of the dust, while FY-2H satellite data provided high-resolution dust distribution patterns. Additionally, the MAIAC AOD product was used to analyze Aerosol Optical Depth, and concentration-weighted trajectory (CWT) analysis was used to identify key dust source regions. The study found that PM10 played a dominant role in the storm, and the AOD values during the storm in Lanzhou were significantly higher than the annual average, highlighting the severe impact on regional air quality. Key meteorological conditions influencing the storm’s occurrence were analyzed, including the formation and eastward movement of a high-potential ridge, convection driven by diurnal temperature variations, and surface temperature increases coupled with decreased relative humidity, which together promoted the generation and development of dust. Backward trajectory and dust distribution analyses revealed that the dust primarily originated from Central Asia, western Mongolia, Xinjiang, and Gansu. From the 19th to the 21st, the dust distribution showed similarities between day and night, with a noticeable increase in dust concentration from night to day due to strong vertical atmospheric mixing. To mitigate the impacts of future dust storms, this study highlights both short-term and long-term strategies, including enhanced monitoring systems, public health advisories, and vegetation restoration in key source regions. Strengthening regional and international cooperation for transboundary dust management is also emphasized as critical for sustainable mitigation efforts. These findings are significant for understanding and predicting the causes, characteristics, and environmental impacts of dust storms in Lanzhou and the Northwestern region.

Published: January 2025

As a kind of industrial solid waste, lead–zinc waste slag can easily cause heavy metal migration in acid environments, resulting in safety risks. Along these lines, in this work, the waste slag of a lead–zinc mining area in western Qinling, Shaanxi, China, was selected as the experimental material. Seven groups of acid soaking solutions with different pH values were set up with three parallel samples in each group, and the acid soaking experiments were conducted for 100 days. During the experiment, the electrical conductivity, pH value, and heavy metal content of the solution, as well as the pore distribution and heavy metal content of the waste slag surface, were measured. The results showed that with pH = 4 and pH = 7 as the environmental limit values, the pH value, electrical conductivity (EC), and heavy metal contents in the solution changed to different types after the waste slag was soaked in the solution with a pH of less than 4 and the solution with a pH of 5–7. The release of heavy metals from waste slag exceeded the discharge standard in the environment with a pH of less than 4, and the pore structure of waste slag was obviously enhanced, especially in the soaking solution with an initial pH of 1. The maximum soaking amounts of Zn, Pb, and Cd were 2.584 mg/L, 1.28 mg/L, and 0.0169 mg/L, respectively, during the experiment, which did not meet the “Environmental quality standards for surface water” (GB 3838-2002) and could not be excreted as direct surface water. However, when the environmental pH was greater than 7, the heavy metals showed reverse adsorption. This result indicated that when the acid soaking solution entered the alkaline range, the heavy metal content in the solution was less, which can basically meet the discharge standard. However, the pores of waste slag continued to expand. Our work provides valuable insights into the treatment of waste slag and environmental protection in lead-zinc mining areas containing sulfur.

Published: January 2025

Some of the rural areas in Central Java still have the highest maternal mortality rate. Preeclampsia is the leading cause of maternal death in Indonesia. One of the factors contributing to the oxidative stress associated with preeclampsia is lead exposure. Various studies have clearly shown that superoxide dismutase deficiency (SOD) and increased homocysteine (Hcy) levels are consistently associated with the incidence of preeclampsia. Several studies also show the role of MTHFR A1298C and C677T gene polymorphisms in the occurrence of preeclampsia. This study investigated the association between lead exposure, blood SOD and Hcy levels, and MTHFR A1298C and C677T gene polymorphisms in Preeclampsia. This analytical observational case-control study was conducted in 70 cases of preeclampsia and 70 controls. Blood SOD and Hcy levels were measured using Enzyme Linked Immunosorbent Assay (ELISA). Lead level was determined by atomic absorption spectrometry (AAS). MTHFR A1298C and C677T gene polymorphism was genotyped using polymerase chain reaction-restriction fragmentlLength polymorphism (PCR-RFLP). The data obtained were analyzed using the Mann-Whitney U test, chi-square test, independent samples T-test and multivariate linear regression analysis. There was a significant difference (p=0.001) between the lead level in preeclampsia group (mean: 44.50±10.72) compared to the control (mean: 32.78±14.40). The homocysteine level in the preeclampsia cases (mean: 9.06±4.03) also differed significantly (p=0.004) from that of the control group (mean: 7.18±3.09). Increased levels of blood lead and homocystein levels are associated with the incidence of preeclampsia. We found no significant difference in SOD levels, MTHFR A1298C and C677T gene polymorphism between preeclampsia and control group.

El maíz criollo (Zea mays) costarricense ha venido desapareciendo gradualmente debido a la sustitución por híbridos de alto rendimiento, urbanización de zonas agrícolas, altos costos de producción y el escaso interés de las nuevas generaciones por su conservación. La caracterización morfológica del maíz criollo permite evaluar, describir y cuantificar la magnitud de la variabilidad de estas poblaciones y en Costa Rica hay poca investigación de este tipo. El objetivo de esta investigación fue caracterizar morfológicamente maíces criollos nativos de la región Central y Atlántica de Costa Rica. Se recolectaron muestras de maíz criollo en 11 cantones de febrero 2018 a marzo 2020. Se evaluaron variables cuantitativas y cualitativas tanto en mazorca como en grano. Para cada región se realizó un análisis descriptivo para las variables cualitativas de mazorca y grano y se elaboraron tablas de frecuencias con sus respectivos gráficos. Para las variables cuantitativas se realizó análisis de varianza multivariado (P ≤ 0,05) y análisis de conglomerados jerárquicos por región, utilizando la distancia de Gower y el método de agrupamiento Ward. En la región Central se encontró alta variabilidad en diámetro de mazorca, granos por hilera, longitud de mazorca, número de hileras, peso de mazorca, así como en ancho, grosor, longitud y peso de grano. Los maíces de la región Atlántica presentan granos de menor tamaño que los de la Región Central. En el análisis de conglomerados, en la Región Atlántica se encontraron dos grupos, donde predominan los granos de color naranja, mientras que en la región Central se encontraron tres grupos, donde predominan los granos blancos y en menor grado los amarillos y púrpura. Este estudio evidenció la presencia de una importante variabilidad morfológica en las mazorcas y grano de maíces criollos tanto en la región Central como en la Atlántica de Costa Rica.

México cuenta con una gran diversidad genética de maíz (Zea mays L.) representada por maíces nativos con adaptación, color, textura y sabor, entre muchas otras características diferenciadas. Esta gran diversidad constituye una oportunidad para la generación de maíces especializados con mayor valor agregado, que pueden tener impacto en la alimentación y salud humana, pecuaria y en la industria de transformación. El color del grano es una de las características que representan esta diversidad, con tonalidades que van desde el negro hasta el rosa pálido, pasando por los colores rojo y azul/morado, que son los más comunes (Salinas et al., 2010). El maíz pigmentado (o de color) tradicionalmente se emplea como ingrediente para diversos platillos típicos. Los pigmentos presentes en el maíz tienen potencial para ser utilizados con fines de investigación en áreas de la salud, nutrición, industria de alimentos y cosméticos (Urias-Peraldi et al., 2013). Los compuestos responsables de los colores en el grano de maíz son las antocianinas, las cuales poseen capacidad antioxidante, anti-mutagénica y anticancerígena, que se han relacionado con la prevención de ciertas enfermedades del sistema circulatorio y diversos tipos de cáncer, en particular del sistema digestivo (López-Martínez et al., 2009; Zhao et al., 2009). Salinas et al. (2012) informaron que en poblaciones de maíz de grano azul los pigmentos se localizan en la capa de aleurona, en tanto que en los maíces granate/rojo el pigmento está localizado principalmente en el pericarpio y, en los maíces magenta se encuentran en ambas estructuras (pericarpio y capa de aleurona).

Published: January 2025

This research paper focuses on developing a mathematical model to assess the parametric sensitivities of an operational induction motor equipped with a solid hollow ferromagnetic rotor. The analytical approach involves integrating principles from both electromagnetic circuit theory and electromagnetic field theory. The derivation of the parametric sensitivity matrix entails constructing differential equations, specifically the first variation equations derived from the motor's electromechanical state equations. The study further extends its analysis by conducting computer simulations to explore the parametric sensitivities related to the material composition of the rotor body and the characteristics of the input signal. The results of these simulations provide valuable insights into how alterations in these parameters impact the motor's performance. By combining theoretical foundations with practical computational simulations, this research offers a comprehensive understanding of the interplay between various factors influencing the behavior of the induction motor with a solid hollow ferromagnetic rotor.
