Authors: Ariani  , Arminsih Ririn
Published: July 2024

Purpose: This study aims to analyze the correlation between climate variability (temperature, humidity, rainfall, sunshine duration, and wind speed), population density, altitude, and low birth weight (LBW) rate on the incidence of under-five years old children with pneumonia.
Methods: This research uses a combination study design based on place and time (mixed design ecological study).
Results: There was no significant relationship between climate variability and lag effect of 0-2 months with the number of under-five pneumonia cases in Bogor Regency in 2018-2022, as well as the altitude variable (p=0.0619). Meanwhile, the variables of population density (r-value = 0.439) and LBW rate (r-value = 0.338) showed a positive correlation with the number of under-five pneumonia cases in Bogor Regency.
Conclusion: This research shows the incidence of pneumonia among under-fives in Bogor Regency is influenced by population density and LBW rates. Ensuring access to proper sanitation, a complete basic immunization program, adequate housing, and also personal protective measures are important to reduce the spread of pneumonia.

Published: July 2024

Bacillus sp. is a Plant Growth Promoting Rhizobacteria (PGPR) species that lives in the rhizosphere. This bacterium can produce antifungal compounds that suppress pathogenic fungi, such as Fusarium oxysporum. The aim of this research was isolate, characterize, and obtain Bacillus sp. that can inhibit F. oxysporum which causes twisted disease in shallots. Isolation was done by sampling 10 g of soil from shallot roots, placing it in 9 mL of sterile water, and carrying out a series of dilutions. The first dilution was incubated at 80 °C for 20 minutes to obtain Bacillus sp. on the selective medium HiChrome. Colony morphology, shape, cell color, Gram staining, catalase and endospore staining were observed from obtained isolates. An antagonist test was done to determine the inhibitory effects of isolates against the pathogenic fungus F. oxysporum. Four isolates of Bacillus sp. were obtained with irregular colony shape, dull white color without muccus, edges varying in shape between lobate and undulate, and raised elevation. The results of the antagonist test showed that the four isolates had the ability to inhibit the growth of the pathogenic fungus F. oxysporum with the greatest inhibition shown by isolate BM1 at 30.12%, with an antibiosis mechanism and hyphae swelling.

Rhizospheric fungi can have serve as biological agents against plant pathogens Alternaria alternata, which infects carrot plants. Rhizospheric fungi are more abundant in organic lands. This study aims to isolate fungi from organic carrot’s rhizosphere that are able to suppress A. alternata’s growth and determine isolate rhizospheric fungi ability to inhibit A. alternata to identify potential biological control agents against A. alternata. This research was conducted at the Laboratory of Biotechnology and Basic Biology, Diponegoro University, between January–June 2023. Research methods include survey location, soil sampling, rhizospheric fungi isolation, pathogenic fungi isolation, creating growth curve, pathogenicity tests, antagonism tests, and fungi identification. This study used a complete randomized design (CRD) and was analyzed using ANOVA at the 5% level of significance and Duncan's hoc-posttest. Fungi isolation from organic carrot plant’s rhizosphere resulted in 13 isolates consisting of six genera: Penicillium, Aspergillus, Paecilomyces, Myrothecium, Trichoderma, and Simplicillium. The antagonism test showed that eight antagonistic isolates, including the genus Penicillium (WO1, WO6, WO10), Paecilomyces (WO5), Myrothecium (WO7), Trichoderma (WO9), and Aspergillus (WO11, WO13), where WO1, WO6, WO10, and WO11 have a medium percentage of inhibition (44.12-57.84%), while WO5, WO7, WO9, and WO13 have a high percentage of inhibition (64.29-76.06%). The eight isolates showed antagonism mechanisms, including antibiosis (WO1, WO5, WO6, WO7, WO10, and WO11) and parasitism (WO9 and WO13).
Pancasila in National Curriculum: Political Education or Doctrination?
Authors: Wicaksana Ibnu Andy
Published: July 2024

This article examines the operation of Pancasila, the Indonesian state ideology, in school courses in an Indonesian school in the Netherlands, “Sekolah Indonesia Den Haag” (SIDH). It aims to examine the way Pancasila is taught at SIDH, whether it functions as political education or political indoctrination. The study was conducted using qualitative data analysis, with data from interviews and field observations. The findings show that the way Pancasila is taught at SIDH is a dynamic process consisting of both cultural value and critical engagement to help students understand Indonesia's cultural heritage and instill national identity. The findings also indicate that Pancasila is taught as political education, predominantly relying on rote memorisation and prescribed textbooks, within the context of Dutch liberal cultural values. This leads to identity conflicts among the students. The findings in this study can inform policymaking in education and the formulation of curriculum. For example, to promote a more holistic understanding among students, we can foster critical thinking and open dialogue and encourage interdisciplinary exploration. Investing in teacher professional development may also facilitate meaningful teaching beyond nationalistic symbolism.
Qualities of Literary Machine Translation: A Corpus-based Case Study
Authors: Jiaxin Tian
Published: July 2024

The research assesses and compares the translation performance of two popular machine translation systems, GPT-4o and Youdao AI Translate, in translating into English ten Chinese prose essays excerpted from Selected Modern Chinese Essays 2 by Zhang Peiji. The goal is to discover their linguistic features and investigate how well they can perform in this translation. Through a corpus-based analysis, the research explores the STTR and word/ sentence length of their translations and conducts both automated and human evaluations on their translation quality. It reveals that GPT-4o exhibits higher lexical variety and both the two machine translation systems tend to produce more and shorter sentences than the human translation does. Both of them perform surprisingly well in the translation, as they get relatively high BLUE scores yet low TER scores, as well as high adequacy and fluency rates. Our evaluation results also show that Youdao AI Translate displays generally better performance than GPT-4o in the translation of Chinese-to-English literary texts, and they can complement each other to achieve even better performance, though a certain amount of errors are still present in both of their translations.

Authors: García Alcalá Jesús Ulises , Sánchez Castillón Jorge Alejandro , Castro Sataray Omar
Published: July 2024

La empatía como elemento en el establecimiento de relaciones interpersonales permite la conexión con los demás para la generación de vínculos significativos (Preston & De Waal, 2002).  Dentro del entorno social, investigaciones previas han sugerido que la empatía se relaciona con el funcionamiento psicosocial y mantenimiento del orden social por medio del desarrollo de comportamientos adaptativos como el respeto y apoyo hacia otras personas, a lo que algunos autores denominan conducta prosocial. El objetivo del presente estudio es analizar la relación entre la empatía, las conductas prosociales y la satisfacción con la vida. La muestra está conformada por 392 personas (M = 31.85, DT = 15.10), hombres y mujeres entre 18 y 71 años en Puerto Vallarta, Jalisco. Los resultados denotan correlaciones estadísticamente significativas de la empatía con las conductas prosociales y la satisfacción con la vida. Las personas con mayor empatía afectiva y cognitiva destacan en el acontecimiento de conductas prosociales y las personas con mayor empatía afectiva presentan menor satisfacción con la vida.
Involvement of NPY-Y1 Receptors in Periaqueductal Gray on Anxiety, and Food, Sucrose, and Alcohol Consumption in Pre-exposed Wistar Rats
Authors: Vázquez León Priscila , Miranda Páez Abraham , Marichal Cancino Bruno Antonio , Sánchez Castillo Hugo
Published: July 2024

Periaqueductal gray (PAG) is a well-documented region on integrated defensive responses and anxiety-like behavior. However, only recently has been shown its role in drug/alcohol consumption, mainly in the relapse state and associated with anxiety. NPY is known as the major anxiolytic endogen neuropeptide, besides its well-recognized orexigenic action mediated mainly by NPY-Y1 and NPY-Y5 receptors respectively. Herein, we addressed the role of the NPY-Y1 receptor in the dorsal (D)-PAG on anxiety-like behavior through a defensive burying test, as well as the food, sucrose, and alcohol consumption in male Wistar rats, with a sucrose fading paradigm at the juvenile stage as the alcohol intake initiation procedure. Present results confirmed that intra D-PAG NPY is a key modulator neurotransmitter system on anxiety-like behavior. Additionally, NPY significantly increased both the food and sucrose intake and decreased the alcohol consumption in voluntary sucrose (10%) and alcohol at different concentrations models. These results are likely mediated by NPY acting in the NPY-Y1 receptor in the D-PAG.

Authors: Toro Rodríguez Luisa Fernanda , Ruiz Ortega Francisco Javier
Published: July 2024

Este artículo aborda la importancia de considerar los niveles de representación como criterio para seleccionar el texto escolar como herramienta de apoyo para la enseñanza de la química. La metodología utilizada en la investigación es de carácter exploratorio, basada en el análisis documental de 6 textos que fueron analizados por medio de la aplicación de las rúbricas de (Caamaño Ros, 2014; Gómez Mora, 2019; Valladares et al., 2001). El análisis de los resultados evidencia obstáculos como la deficiencia en las representaciones de orden microscópico, la relevancia que se da al nivel simbólico, sin articularlo con otros niveles o con un lenguaje que permita el acercamiento a este nivel. Como sugerencia se propone una rúbrica que expone criterios de orden conceptual y metodológico que orientaría a cada docente a seleccionar un buen texto escolar.

Green Synthesis and Characterization of Zinc Oxide Nanoparticles Using Nyctanthes arbor-tristis Plant Extracts: Assessing Photocatalytic Properties
Authors: Kumar Anil , Shrotriya Dr. Anil Kumar
Published: July 2024

Abstract: In this work, zinc oxide (ZnO) nanoparticles are synthesised and characterised in an environmentally friendly manner, and their potential uses in photocatalytic processes is investigated. The green synthesis of ZnO nanoparticles involved the utilization of zinc nitrate hexahydrate (Zn(NO3)2·6H2O) and Nyctanthes arbor-tristis Plant Extracts. The nanoparticles were synthesized at an optimal temperature of 60 ◦C. The samples were analysed using energy-dispersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), Dynamic Light Scattering(DLS) and UV-visible spectroscopy to determine their characteristics. ZnO nanoparticles were identified by a distinctive peak at 302 nm in UV-visible spectroscopy. SEM confirmed the nanoscale size and morphology of the ZnO particles. The elemental information obtained from the EDX examination showed that oxygen made up 22.2% of the atomic weight and zinc made up 45.6%. The diffractogram was indexed by XRD analysis at different angles that corresponded to ZnO nanoparticles. DLS determined the average crystalline size, which was 87.5 nm. FTIR examination revealed a distinctive signal at 1051 cm−1, suggesting that the nanoparticles contain functional groups. The produced nanoparticles had strong photocatalytic activity, especially when Methyl Blue was exposed to UV light and began to degrade. Rate constants and correlation coefficients were used to examine how the addition of ZnO nanoparticles affected the photocatalytic degradation process' kinetics. These nanoparticles were synthesised using an economical and ecologically friendly process. This work offers potential directions for further investigation and applications in the fields of nanotechnology, biosensor development, and water remediation.

Authors: Kumari Riju , Kumar Gautam
Published: July 2024

Abstract: The seismic analysis of buildings is crucial for ensuring structural safety and resilience against earthquake forces. Irregularities in building configurations pose unique challenges, influencing the distribution of seismic forces throughout the structure. This study focuses on the seismic analysis of a G+12 building characterized by irregularities in plan and elevation using STAAD.Pro software. Here we have taken four models consisting of bare bay frame , bay frame with shear wall on one corner, , bay frame with shear wall on two opposite corners, , bay frame with shear wall on all corners for the further analysis. This research contributes to enhancing understanding and design practices for irregular high-rise buildings, emphasizing the importance of advanced analytical tools in seismic engineering. From this analysis we can conclude that within all four models ,building having shear wall on all four sides shows minimal deflection attributed to its maximum stiffness characteristics, hence considered most stable

Published: July 2024

Introducción: La muerte es parte de los tabúes sociales existentes y puede fomentar actitudes que distan de su abordaje explícito en relación con los cuidados. Objetivo: Analizar las actitudes ante la muerte en profesionales de enfermería de acuerdo con las publicaciones científicas en el contexto latinoamericano en el período 2018 a 2022. Metodología: Se realizó una revisión de literatura integrativa de las publicaciones científicas latinoamericanas respecto de las actitudes ante la muerte en el contexto de la enfermería, empleando los siguientes términos estandarizados: actitud, muerte, enfermería y cuidados de enfermería. Se incluyeron 8 artículos publicados en el período definido, en idioma español y portugués, en los que se abordó explícitamente la temática de la revisión. La información de los artículos fue analizada tomando como referencia los conceptos de la teoría de las transiciones. Resultados: Se encontraron diseños tanto cuantitativos (50 %) como cualitativos (50 %), elaborados en su totalidad en el ámbito hospitalario. Los principales resultados dan cuenta del predominio de la indiferencia ante la muerte en el contexto de los cuidados. En relación con la teoría de las transiciones, la mayoría de los artículos abordan las condiciones en que estas se dan, además de los conceptos de terapéutica de enfermería y patrones de respuesta. Conclusiones: La producción de investigaciones sobre la actitud ante la muerte en profesionales de enfermería es escasa en Latinoamérica. Las experiencias de pérdidas cercanas, la capacitación y el soporte institucional son la base para contribuir a una mejor actitud hacia la muerte.

employees in the financial industry in Taiwan, who were selected because they were in positions where they were unable to work from home during the pandemic. The results revealed that job demands and emotional exhaustion were associated with UPBs. This study sheds light on the challenges faced
by frontline workers with specialized knowledge who were unable to work remotely during the COVID-19 pandemic, and expands understanding of the antecedents of UPBs. Implications, limitations, and future research directions based on the findings are discussed.
Childhood trauma and nonsuicidal self‐injury in vocational students: A moderated mediation model
Authors: Yang Ling , Sun Chenzhe , Cao Hua , Li Yanjun , Cui Yuna , Wu Yongyong , Li Qianqia
Published: July 2024

It is a matter of public concern that the risk of nonsuicidal self‐injury (NSSI) is high among vocational college students. The benefits and barriers model of NSSI considers childhood trauma an important vulnerability factor that influences NSSI through negative self‐schema.
Therefore, exploration of possible protective factors is necessary to inform NSSI interventions. We investigated the potential protective function of Chinese cultural beliefs about adversity and whether negative self‐schema mediates the connection between childhood trauma and NSSI.
Questionnaires were completed by 898 vocational college students aged 18â–“23 years. The results indicated that childhood trauma directly predicted NSSI and also indirectly predicted NSSI via negative self‐schema. Additionally, Chinese cultural beliefs about adversity,
as a vulnerability protective factor, moderated the relationship between childhood trauma and NSSI (i.e., the first half of the mediation effect). Thus, a self‐schema and adversity belief-based intervention can help to prevent NSSI behavior among vocational college students.

Authors: Xu Yuanyuan , Manap Jamiah , Aziz Siti Fardaniah Abdul , Ngah Farhah Hanun
Published: July 2024

This paper provides in-depth knowledge regarding the fundamental factors influencing college students’ childbearing intentions. We used PubMed, ProQuest Dissertations, Web of Science, EBSCOhost, Scopus, and China National Knowledge Infrastructure to search for relevant articles
published between January 1946 and April 2023. Among these, we incorporated 51 studies conducted in 20 countries into a quantitative synthesis. The results indicated that there were differences between developed and developing countries in terms of the factors influencing college students’
childbearing intentions. The primary factors affecting childbearing intentions in developed countries were fertility knowledge, personal pursuits, and partner relationships. However, the influencing factors in developing countries were more complex: Financial pressures and personal pursuits
deterred college students from their aspirations to have children, and these challenges delayed their intended reproductive age. Implications of the findings are discussed.

Authors: Mi Yue , Jiang Chuanxing
Published: July 2024

In the field of educational psychology, it is crucial to explore the mental health of students within specific disciplines. In this research we targeted 469 college students majoring in music, delving into the interplay between their self‐esteem and social anxiety, and particularly
analyzing whether fear of evaluation acts as a bridge between these two factors. The findings revealed a clear trend: lower self‐esteem was associated with higher levels of social anxiety, with fear of evaluation playing a key mediating role in this dynamic. This insight provides a
perspective on how self‐esteem affects social anxiety among music students through the pathway of fear of evaluation. Educators and mental health professionals dedicated to student welfare should adopt a range of targeted intervention strategies aimed at boosting students’ self‐esteem
as an effective means to alleviate their social anxiety.

Addressing Stress Among Healthcare Workers Using Mindfulness-Based Interventions
Authors: Dave Pallav
Published: July 2024

Stress is rampant among healthcare workers in different patient care settings. Healthcare workers are one of the groups that report high workplace stress levels with some studies reporting these levels to be as high as 70 to 90%. Stress was particularly rampant among healthcare workers during the COVID-19 pandemic because most workers were overwhelmed and could not provide the best care for their patients. Stress among healthcare workers is likely to continue because the work conditions that contribute to this high level of stress are becoming more rampant. For instance, demanding work, long and unpredictable work hours, and high administrative burdens continue to be rampant. Other factors such as an increase in the number of people affected by multiple chronic conditions and the aging workers are also putting a lot of strain on healthcare and among healthcare workers. Considering the staff shortages, taking care of people with numerous needs can increase stress levels which explains why healthcare workers report high levels of stress. Considering the negative effects of stress on healthcare workers' health and well-being, it is important to have effective interventions in place to deal with this stress such as mindfulness training. Research has shown that mindfulness-based interventions have a lot of potential when it comes to addressing work-related stress. It also helps to deal with depression and anxiety.

Transformações no setor de saneamento no Estado do Rio de Janeiro: neoliberalização e mudanças regulatórias
Authors: Tavares Érica , Souza Juliana Santos Alves de , Ribeiro Carlos Frederico Rangel de Almeida
Published: July 2024

Este artigo tem como objetivo analisar a reconfiguração da prestação do serviço de abastecimento de água nos municípios do estado do Rio de Janeiro, buscando identificar como as novas investidas do processo de neoliberalização no setor de saneamento básico no Brasil promovem a fragmentação na oferta dos serviços e a produção de geografias desiguais na escala regional, sob a lógica da experimentação de políticas, sobretudo após a aprovação da Lei nº 14.026/2020. O estudo se fundamenta em uma abordagem sobre a mercantilização dos serviços públicos no contexto de neoliberalização marcado por uma complexa reformulação dos mecanismos regulatórios. A metodologia baseia-se na análise de dados secundários, pesquisa documental e mapeamento temático. Os resultados indicam que a gestão dos serviços de saneamento tem se orientado cada vez mais por uma lógica de mercado, com experimentação de mecanismos regulatórios controversos que reforçam a fragmentação e a desigualdade territorial.
Mixed convection studies of liquid metal MHD flow in a horizontal square duct subjected to a strong uniform magnetic field
Authors: Wu Xiaodong , Mao Jie , Yan Jiawei , Yang Lang
Published: July 2024

The heat transfer of liquid metal blankets is one of the key issues that need to be solved in the design and manufacture of controlled thermal nuclear fusion reactors. Under actual working conditions, the buoyancy force changes the flow state of the liquid metal and thus affects the heat transfer of the blanket. In this paper, a low magnetic Reynolds number magnetohydrodynamic (MHD) solver is developed in OpenFOAM to simulate a liquid metal flow in a horizontal square duct under a transverse uniform magnetic field and surface heating. The effects of wall conductance ratio and Grashof number on the velocity, temperature, MHD pressure drop, and heat transfer are studied. The results show that the wall conductance ratio does not change the temperature distribution and heat transfer significantly, and the MHD pressure drop increases with the increase of the wall conductance ratio. The effects of the Grashof number on the mixed convection heat transfer are closely related to the critical Grashof number. When the Grashof number is less than the critical Grashof number, the flows in the duct are in a stable laminar flow state. When the Grashof number is greater than the critical Grashof number, the buoyancy force forms a transverse circulation, affects the temperature distribution followed by the broken velocity symmetry, and improves the heat transfer of the duct. The results can be referenced in the design of liquid metal blankets. Key words: Mixed convection, buoyancy force, wall conductance ratio, horizontal square duct, uniform magnetic field.

Electrovortex flow and melt homogenization in the industrial direct current electrical arc furnace
Authors: Pavlovs S. , Jakovičs A. , Chudnovsky A.
Published: July 2024

The paper presents the computations results on the turbulent electrovortex flow and temperature field in the melt and the results on the concentration field of alloying additive in an industrial-scale (3.6 t of molten steel) electrical arc furnace with direct current power supply over one top and two bottom electrodes. The developed and experimentally verified numerical model is applied. The Large Eddy Simulation model of turbulence is used. The influence of complicated geometry (vertical blades) of the bottom electrodes on electrovortex flow regimes is compared with that of electrodes of conventional geometry. Melt flow patterns near the electrodes' blades are also observed at the melt mirror for the developed laboratory-scale experimental setup (4.8 kg of GaInSn). Melt homogenization is considered for: (i) the temperature field when the heat flux from the arc is injected at the arc spot zone at the melt mirror; (ii) the concentration field when the mass flux of alloying additive is introduced at a chosen zone of the melt mirror.

Effect of viscosity on tornado-like flow driven by a spinning magnet
Authors: Grants I.
Published: July 2024

Tornado-like flow is created by a cylindrical transversely magnetized permanent magnet rotating co-axially below a conducting liquid cylinder. Several geometries are considered numerically, with a focus on the low-Reynolds number regime. The effect of viscosity is discussed in terms of dimensional analysis. The increased viscosity decreases the maximum swirl just slightly as long as the flow remains dominated by inertia. The secondary downdraft slightly increases with the viscosity in this regime, reaching a maximum at the dimensionless electromagnetic torque value around 2×104 in all considered geometries. The maximum is accompanied by a vortex breakdown flow. The downdraft velocity decreases rapidly with the viscosity after the maximum. The respective optimum viscosity is shown to increase proportionally to the setup size provided the skin-effect force is limited. Tables 1, Figs 6, Refs 8.

Published: July 2024

The research is aimed at investigating the influence of the cavitation process on the performance of the electromagnetic induction pump with rotating permanent magnets operating in the circulation loop, where low pump inlet pressure values are maintained. Data on the inlet pressure influence on pressure-flow rate curves were obtained by an experimental approach using a disc-type pump with SmCo permanent magnets in experiments. The pump was placed in the test loop operating with liquid sodium, and measurements of the pump characteristics were made. The inlet pressure variation from 0.1 to 3.0 bar influences the maximum flow rate, thus varying it from 2 to 12 l/s. Figs 7, Refs 7.

Published: July 2024

Under terrestrial conditions, the temperature behaviour of a sample in levitation may be different from that observed in microgravity. Here we present the temporal evolution of the polar and equatorial temperatures of a levitating charge of Ni, revealed numerically and experimentally for different AC current modulations. It is demonstrated that the motion of the sample during the AC current modulation should be taken into account. Tables 2, Figs 3, Refs 9.
Eddy-current flow meter response to spherical non-conductive inclusions travelling in a liquid metal

Published: July 2024

In this paper, we address the problem of characterizing the size and position of a spherical non-conductive inclusion in a conductive material. The characterization is done using an Eddy-Current Flow Meter (ECFM), a device usually used to measure the flow rate of liquid metals, but which is also sensitive to the second gaseous phase. ECFM responses to the passage of inclusions in a quiescent liquid metal are computed numerically. The signal amplitude and phase variations are analyzed for inclusions of different radii and radial positions travelling in the pipe. Two parameters are introduced to characterize these variations: the maximum amplitude of the ECFM signal and its corresponding phase. It is shown that a unique relation exists between these parameters and the size and position of the inclusion. The ECFM signal thus provides enough information to determine the size and position of the inclusions by means of an inverse method. This provides valuable information for low void fraction measurement in industrial liquid metal flows. Tables 2, Figs 5, Refs 10.

We have developed COCONUT -- a novel MHD solar corona model as a basis for EUHFORIA 2.0 space weather forecasting. The steady-state solution in a numerical domain extending from the solar surface up to 0.1 AU is computed. Here the pre-processed magnetic maps prescribed at the inner boundary determine the magnetic topology. These magnetic maps consist of radial components of Helioseismic and Magnetic Imager magnetograms projected on spherical harmonics with a selected maximum frequency. Within the numerical domain a set of ideal MHD equations with gravity is solved implicitly on an unstructured mesh. This choice of grid allows us to omit the issue of singularities presented at the poles in typically used structured grids. Through heavy parallelization, an optimized CFL profile and other numerical acceleration techniques, we achieved superior convergence times with high robustness and reliability even for numerically challenging cases of maximum solar activity. The MHD solution is generally obtained within a few hours of computation, which is crucial for space weather forecasting systems. Our model passed a series of tests and was further validated using detailed comparison with observations. It successfully recreated magnetic structures (streamers, pseudo streamers, coronal holes) observed during the solar eclipses in March 2015 and in July 2019, thus corresponding to maximum and minimum of solar activity. The COCONUT code will be next extended to include the heating and radiation terms for a more realistic physical description. In the future, a multispecies formulation will be implemented allowing us to consider also the impact of electrons as well as of neutrals on the solution. Figs 3, Refs 10.

In the present work, the kinetics of transport of selected rare earth ions at the liquid-liquid interface in the presence of a magnetic field gradient was investigated. A uniform magnetic field was applied to the classic liquid-liquid solvent extraction system. The influence of temperature, initial concentration of selected ions and magnetic field gradient on the extraction rate was determined. It was shown that the uniform magnetic field could affect the kinetics of the extraction of rare earth ions in the liquid-liquid system. The observed differences constitute a promising prospect worthy of further research. Figs 6, Refs 10.

Magnetic fields are key ingredients for heating the solar corona to temperatures of several million Kelvin. A particularly important region with respect to this is the so-called magnetic canopy below the corona, where sound and Alfvén waves have roughly the same speed and can, therefore, easily transform into each other. We present the results of an Alfvén-wave experiment with liquid rubidium carried out in a pulsed field of up to 63 T. At the critical point of 54 T, where the speeds of Alfvén waves and sound coincide, a new 4 kHz signal appears in addition to the externally excited 8 kHz torsional wave. This emergence of an Alfvén wave with a doubled period is in agreement with the theoretical predictions of a parametric resonance between the two wave types. We also present preliminary results from numerical simulations of Alfvén and magneto-sonic waves using a compressible MHD code. Figs 4, Refs 14.
