High-frequency variability dominates potential connectivity between remote coral reefs
Authors: Vogt-Vincent Noam S. , Mitarai Satoshi , Johnson Helen L.
Published: January 2024

Abstract. Coral larval dispersal establishes connectivity between reefs, but larval fluxes vary over timescales from daily to multidecadal due to oceanographic variability. Using a 2 km-resolution ocean model, we simulate daily spawning events from 1993–2019 (for a total of almost 10,000 events) across all coral reefs in the tropical southwest Indian Ocean. Although there is a significant seasonal cycle in potential connectivity at many reefs, day-to-day variability generally dominates. The importance of this day-to-day variability depends on the local geography and oceanography. Stochastic oceanographic variability introduces considerable uncertainty to dispersal predictions, imposing significant limitations on what dispersal simulations can tell us about connectivity. Protracted spawning over only a few days can significantly reduce variability associated with the likelihood of a larva settling successfully. The duration of spawning is therefore likely a more important parameter in modelling coral connectivity than the exact timing of spawning onset. Finally, we find that a small proportion of spawning events account for the majority of successfully settling larvae, particularly at remote islands, and demonstrate that a time-mean picture of dispersal may be inappropriate for predicting demographic and genetic connectivity.

Introduction: In general, food coloring can be obtained from natural dyes and safe synthetic food dyes. Natural dyes are sometimes considered less stable and less durable than synthetic food dyes. Although there are synthetic dyes that are safe for food, there are still people who use materials that are not suitable for use in food. The use of harmful food dyes must be monitored and recognized for their existence. Harmful food dyes that are commonly found are textile dyes such as Rhodamine B or methanyl yellow. Because it is not a proper food coloring, consumption of foods containing this ingredient can cause a series of health problems for those who consume it, especially in a relatively long period of time. This education aims to allow students to distinguish foods that use natural coloring agents and artificial coloring agents. The results of this activity students can find out the characteristics of foods that use harmful dyes and know the prevention that can be done.

Objective: The purpose of this service is for SMAN 1 SUKADANA students to know the dangers of using hazardous coloring agents in food.

Method: The method used is providing education by providing material to students, tests before and after material on the Use of Harmful Coloring Substances in Food.

Result: Increased knowledge and attitudes of students are tested through pre-test and post-test. There has been an increase in knowledge in students about the dangers of using harmful dyes in food in general by 20%, so that the realization of the purpose of this service is expected to be able to distinguish food ingredients that contain harmful coloring agents in food and those that do not contain harmful coloring agents in food. Basically, knowledge and attitudes also depend on the high or low level of education of students. Therefore, the existence of this counseling can help students in adding insight into the dangers of using harmful dyes. The implementation of this activity can run well due to positive support in the implementation process, where support from various parties and there are no obstacles whatsoever.

Conclusion: The socialization activity on the use of dangerous coloring substances in food to students at SMAN 1 Sukadana received a good response from the school and also students. With outreach activities regarding this, students will understand and be more careful in choosing food to avoid these chemicals.
Students' historicisation of the environmental crisis: A narrative of industrialisation, ignorance and greed
Authors:   Stockholm University, Sweden, Gripe Albin Sönnergren , Sandahl Johan ,   Stockholm University, Sweden
Published: January 2024

As the field of history education begins to acknowledge the need to respond to the challenges of the Anthropocene, questions arise concerning students' ability to use history to make sense of pressing environmental issues. To address this, 67 Swedish upper secondary school students were asked to historicise issues like global warming and share their ideas concerning the present and the future. Within the framework of Jörn Rüsen's narrative theory, this article analyses how and to what extent these students experienced and interpreted the past and used history to orient themselves in relation to such issues. It also develops on the outcome of this process. While most students historicised the situation, many students made limited use of history. Their typical narrative can be described as a linear story of historical industrialisation driven by the hunger for progression and wealth and facilitated by ignorance. It was told with little detail or reference to evidence and in a way that generally seemed unsupported by historical thinking. Moreover, their typical narrative mostly aligned with the standard science-based Anthropocene narrative, lacking cultural and political perspectives. Although their orientations varied, students focused on technical solutions and lifestyle adjustments rather than civic engagement and politics. Students were worried about the future. However, the narrative of technological and scientific progression and the belief that people in the past lacked awareness and technological alternatives gave students hope. On the other hand, viewing them as informed or inherently selfish contributed to pessimism. Supported by theoretical work, the findings indicate ways school history may support students' ability to deal with Anthropocene issues, helping them to experience and interpret the past and the present in a more nuanced and elaborate way. They also highlight the need for content that aids students' ability to anticipate Anthropocene scenarios and reflect on strategies for engagement.
The banal significance of family history research: Experiences and narratives from participants of Swedish non-formal family history courses
Authors:   Jönköping University, Sweden, Blom Karen Ann
Published: January 2024

Is family history research always life-changing and sensational? Or is there something significant in the banal that the participants in this study reported? This study aims to explore the spectrum of experiences of family history research, focusing specifically on the banal. I argue that it is in examining the banal everyday motivations, experiences, and findings that a greater understanding of how the average individual negotiates and builds meaning through their use of cultural heritage, family history, and the past. The everyday banal is what is reproduced and remains after the effervescence fades away and the normal redundancy in traditional society continues. The banal withstands the sands of time and effectively (re)produces narratives and binary tropes of identity and the past. This study examines the narratives collected from semi-structured interviews with seven participants from two Swedish non-formal courses in family history research. These narratives are important as they reveal participants’ engagement with historical consciousness and the relationship between the past, present and future. Moreover, the stories they tell are significant in revealing that participants learn family history research for numerous reasons, including “something to do” alongside those who wish to have a deeper historical understanding. Family history research is a collective and collaborative activity despite the individualised nature of focusing on one’s ancestors. Participants’ research led to discoveries that were not always revolutionary, reinforcing, for example, banal traits seen in themselves and banal activities they carry out today. This study found that while the reasons for participation, the act of attending class, and participants’ research may not necessarily result in the extraordinary–thieves or kings–for these individuals participating in family history research, the banal reasoning and banal results are significant.

In this study, we investigated the role of an observation instrument on teaching historical thinking and reasoning (HTR) in fostering teachers’ capability to teach historical reasoning. The aim was to see how Teach-HTR, an observation instrument that focusses on teacher behaviour when teaching HTR, can be used to enhance the professional growth of history student teachers in its teaching. We conducted a case study focusing on teacher training where a teacher educator integrated the use of the instrument in his regular practice. After investigating the changes in student teachers’ beliefs, knowledge and practices by conducting pre- and post-measurements we used the Interconnected Model of Professional Growth to examine it further. The case study shows the Teach-HTR observation instrument helps student-teachers identify the teacher behaviour that enhances the teaching of HTR. It provides indications of the instrument’s utility in enhancing professional growth.

Introducción: La Pandemia COVID-19, ha tenido impactos negativos en la salud física y mental de las personas, así como las medidas adoptadas por los gobiernos, para prevenir el contagio masivo de la población como el confinamiento, el aislamiento social, el trabajo y educación virtual. Dentro de los afectados por estos cambios, se encontrarían los estudiantes universitarios del área de la salud, que además de estudiar en estas condiciones de pandemia, no han podido hacer sus prácticas de los servicios de salud. Esta situación de exposición al aislamiento, podría afectar la salud mental de los jóvenes estudiantes universitarios.  Objetivo: determinar los niveles de depresión, ansiedad y estrés en estudiantes universitarios y su relación con variables sociodemográficas y las características del aislamiento social durante la Pandemia COVID-19..

Métodos:  Se realizó un estudio descriptivo, observacional, de corte transversal y cuantitativo, con una muestra de 818 estudiantes universitarios de facultades de ciencias de la salud, mediante el cuestionario autoadministrado DASS-21.

Resultados:  Los principales hallazgos fueron: una mayor prevalencia en niveles altos (severos y extremadamente severos) en la ansiedad, alcanzado casi a 4 de cada 10 de los evaluados; por otro lado, en depresión y el estrés, 2 de cada 10 de los evaluados, se encontraron en los niveles mencionados. En relación con las variables sociodemográficas, las relacionadas con el COVID-19 y aislamiento social, se hallaron diferencias estadísticamente significativas con el género (mujeres > varones), el haber tenido COVID-19 (Si > No) y vivir con familiares como antes de la pandemia (Si > No) obtuvieron en promedio mayores puntajes en depresión, ansiedad y estrés. Conclusión: Los estudiantes que presentaron mayor depresión, ansiedad y estrés con una diferencia significativa fueron de género femenino, con antecedentes de haber tenido Covid-19, menor contacto con famiiares y haber cumplido con aislamiento social total
Salud en la Frontera: Desafíos y Oportunidades para el Bienestar de las Comunidades Fronterizas
Authors: Rios-González Carlos Miguel
Published: January 2024

La salud en la frontera presenta una serie de desafíos y oportunidades para el bienestar de las comunidades fronterizas. Estas zonas geográficas, donde los límites políticos y territoriales se entrelazan, enfrentan problemas de salud únicos que requieren enfoques innovadores y colaborativos. Uno de los desafíos principales es el acceso limitado a servicios de atención médica de calidad. Las comunidades fronterizas a menudo carecen de infraestructuras de salud adecuadas, incluyendo hospitales y clínicas, lo que dificulta el acceso a servicios esenciales. Además, las barreras lingüísticas y culturales pueden dificultar aún más la comunicación entre los proveedores de salud y los pacientes, lo que limita la calidad de la atención. A pesar de estos desafíos, también existen oportunidades para mejorar la salud en la frontera. La colaboración transfronteriza puede ser una herramienta poderosa para abordar los problemas de salud comunes. Los países vecinos pueden compartir recursos, conocimientos y mejores prácticas para fortalecer los sistemas de salud en ambos lados de la frontera. Esto incluye la promoción de la formación y capacitación conjunta de profesionales de la salud, el intercambio de información epidemiológica y la armonización de políticas de salud. Además, las comunidades fronterizas pueden aprovechar su diversidad cultural y su conocimiento tradicional para mejorar la atención médica.

We study the environment of nearby extragalactic radio sources of different morphological type from our sample. We chose 30 3C radio galaxies of different FR class for which we have several observational dates on wavelength from radio to X ray. For the study we select the regions with radius of 500 pc around of the parent galaxy of radio sources. We bring the optical maps of these regions that are overlaid on the radio maps and maps in all available wavelength. The preliminary review show that there are some differences in the neighboring regions around radio galaxies of different FR classes.

Invasive electrical stimulation in the treatment of avascular osteonecrosis of the femoral head — mid-term results
Authors: ELLENRIEDER M , SCHULZE C , GANZLIN A , ZAATREH S , BADER R , MITTELMEIER W
Published: January 2024

The study aimed to evaluate the outcomes of osteonecrosis of the femoral head (ONFH) in adults after surgical treatment including invasive electromagnetic osteostimulation (E-Stim). Further, the influence of disease stage and several comorbidities on the joint preservation rate should be examined.

Sixty patients (66 hip joints) with ONFH were included in this retrospective cross-sectional analysis (mean follow-up: 58 months, 19-110 months). Potential ONFH risk factors and comorbidities (ONFH stage, age, sex, alcohol, smoking, cortisone medication, chemotherapy) were recorded. The influence of specific parameters on the joint preservation rates was evaluated by a multivariate logistic regression analysis. Finally, patients with preserved hip joints underwent an assessment of their last available X-rays.

The joint preservation rate depended on the initial ONFH Steinberg stage (I+II: 82.8%, III: 70.8%, ≥ IVa: 38.5%). Initially collapsed ONFH (p ≤ 0.001) and cortisone therapy (p = 0.004) significantly decreased the joint preservation rates. In case of progressed ONFH, the presence of ≥ 2 risk factors resulted in higher THA conversion rates (stage III: OR 18.8; stage ≥IVa: OR 12). In 94% of the available X-rays, the ONFH stage improved or did not progress. No complications could be attributed to the E-Stim device or procedure.

The present surgical protocol including minimally invasive E-Stim revealed high joint preservation rates for non-collapsed ONFH after mid-term postoperative follow-up. Especially in progressed ONFH, the-risk profile seems to be crucial and hence, for joint preserving surgery, careful patient selection is recommended.

An important factor, which often limits the effectiveness of current biodegradation techniques, is the poor ability of the microbial communities inhabiting the contaminated environments to degrade the pollutants. Therefore, addition of fertilizers of organic and mineral origin, which trigger the metabolic processes of microorganisms and, as a result, stimulate their growth, is a common practice. The aim of our research was to evaluate the effect of a fertilizer on the abundance of microorganisms during soil remediation. The object of study was a soil polluted by a POP complex, that was collected from the territory of a former pesticide storage, located near the village of Slobozia-Duşca, the Criuleni district, the Republic of Moldova. The bioremediation experiments were done in plastic jars, each containing 1,000 g of contaminated soil. The contaminated soil without remediation treatments was used as a control. The experiments were conducted under oxic (Variant 1) and cycled anoxic/oxic conditions (Variants 2-4). Under the oxic conditions the soil moisture was kept constant at 60%. The anaerobic conditions were created by saturating the contaminated soil with water at 80% of the water holding capacity in plastic jars sealed with black polyethylene. The bioremediation experiments were focused on stimulating the indigenous soil microflora by applying a fertilizer. The tested fertilizer contained 50.0% of wood sawdust, 40.0% of iron filings, 10.0% of organic compounds, and was introduced in the amounts of 3.0% (Variant 3) and 6.0% (Variant 4). Thus, for the bioremediation of the polluted soil, there were in total 4 experimental variants. The dynamics of the microbial population in the soil subjected to bioremediation was evaluated during five cycles by the spread plate method. Estimating the total number of microorganisms in the soil samples after 5 cycles of bioremediation showed that the addition of fertilizer significantly stimulated the growth of microorganisms. Most actively the microbial population grew in variant 4 (Figure). Comparing to the polluted soil control, the population of microorganisms in Variant 4 increased by 155 times, and comparing to Variant 1 – by 25.4 times. The remediation by cycled oxic-anoxic conditions (Variant 2) did not have considerable effects on the microorganisms, while the addition of the fertilizer (Variants 3 and 4), under the same conditions, significantly stimulated their abundance. Figure 1. The total number of microorganisms in the soil samples after five cycles of bioremediation Thus, it was established that the tested fertilizer can serve as a bioremediation factor in cyclic anoxic/oxic conditions, stimulating the development of the microbial community in the soil contaminated by POP complexes. Under the conditions of our experiment the best fertilizer concentration was 6.0%.

Published: January 2024

Currently, the attention of researchers is directed towards microalgae and cyanobacteria due to their use as an alternative source of antibiotics. Among the first isolated antimicrobial compounds is chlorelin, from Chlorella sp. which is a mixture of fatty acids that inhibits the growth of both gram-positive and gramnegative bacteria. Eicosapentaenoic acid, hexadecatrienoic acid and palmitoleic acid isolated from Phaeodactylum tricornutum have been shown to possess antimicrobial activity against Staphylococcus aureus gram-positive strain. Thus, the aim of the research was to determine the antifungal activity of 8 strains of microalgae, isolated from the lake "La Izvor". The cultures were isolated by inoculation on liquid and solid mineral nutrient media. Hydroalcoholic extracts (60-70%) from microalgae biomass were used to determine the antifungal activity against phytopathogenic cultures of fungi. Thus, the experiments showed that microalgae strains have antifungal activity against the tested cultures of pathogenic fungi, especially Oscillatoria acutissima and Spirulina major showed a clear inhibitory effect (diameter of inhibition zone more -24mm and 25mm, respectively) against Alternaria alternata. Biomass extracts of O. planctonica, O. brevis (diameter of the inhibition zone of 40 mm) O. acutissima and Chlorella vulgaris, have shown an inhibitory effect on the growth of Aspergillus niger and Botrytis cinerea. An inhibitory action on the growth of the pathogenic fungus Fusarium solani, have presented extracts from O. planctonica, O. acutissima, S. major, Anabaena variabilis and Nostoc verrucosum.

Published: January 2024

One of the most important states in India in terms of agricultural production and industrial growth, Maharashtra is also one of the most important states in terms of the sugar industry in India. It is possible to say that the private sugar industry in Maharashtra has a long and varied history, one that is characterised by a combination of old methods and contemporary innovations. The sugar industry in Maharashtra is an essential part of the rural economy of the state and has far-reaching repercussions for the farming industry on a national scale. It is also a substantial contributor to the total amount of sugar that is produced in India. This study lays the groundwork for a more in-depth examination of the potential and difficulties that characterise the private sugar business in Maharashtra during the subsequent sections. In the following sections, we will delve into the various elements that influence the sector. We will investigate how the industry navigates the complexity of the market, the dynamics of policy, and the improvements in technology in order to ensure that it maintains its position as a significant participant in India's economic landscape. The private sugar industry in Maharashtra is distinguished by the presence of a large number of sugar mills, each of which makes a contribution to the continued socioeconomic development of the region. The sector has faced numerous challenges in recent years, such as unpredictable sugar prices, weather-dependent agriculture, shifting government policies, and the need for technological developments. Despite these challenges, the sugar industry in Maharashtra offers a landscape ripe with opportunities for growth and change.
Mathematical Modelling of a Multi-Stage Feedback Queue with Discretionary Server Downtime
Authors: Rajiv Phillip Kavisha Saxena ,
Published: January 2024

In this section, we take into account an M/G/1x queue in the presence of multiple service tiers, customers who provide feedback at random, and a server who is on vacation. The customer is given the option to progress through a series of k progressively more complex steps in the system. A customer is free to abandon the system after receiving service in the first of  k stages (k > 1). There is a specific order to the stages, starting with the first stage service and continuing on to the second stage service and so on. The customer has multiple opportunities for subsequent service after each phase. However, the re service can only be used from the very beginning, so it doesn't matter which stage he left. Therefore, the customer who requires a different service should go to the very end of the line and wait there. When a server finishes a service for a customer, they may take a short break or move on to the next customer immediately, depending on their schedule. In this article, we extend this model to accommodate a batch arrival queue that allows for a server to take a break.
In Situ Enhancement of Heliostat Calibration Using Differentiable Ray Tracing and Artificial Intelligence

Published: January 2024

The camera target method is the most commonly used calibration method for heliostats at solar tower power plants to minimize their sun tracking errors. In this method, individual heliostats are moved to a white surface and their deviation from the targeted position is measured. A regression is used to calculate errors in a geometry model from the tabular data obtained in this way. For modern aim point strategies, or simply heliostats in the rearmost end of the field, extremely high accuracies are needed, which can only be achieved by many degrees of freedom in the geometry model. The problem here is that the camera target method produces only a very small data set per heliostat, which limits the number of free variables and thus the accuracy. In this work, we extend existing ray tracing methods for solar towers with a differentiable description, allowing for the first time a data-driven optimization of object parameters within the ray tracing environment. Therefore, the heliostat calibration can take place directly within the ray tracing environment. Thus, the image data acquired during the measurement can be processed directly and more information about the orientation of the heliostat can be obtained. Within a simple example we show the advantages of the method, which converges faster and corrects errors that could not be considered before. Without any disadvantages or additional costs, the state-of-the-art calibration method can be improved.
