Abstract. We determine the global emission distribution of the potent greenhouse gas sulfur hexafluoride (SF6) for the period 2005–2021 using inverse modelling. The inversion is based on 50 d backward simulations with the Lagrangian particle dispersion model (LPDM) FLEXPART and on a comprehensive observation data set of SF6 mole fractions in which we combine continuous with flask measurements sampled at fixed surface locations and observations from aircraft and ship campaigns. We use a global-distribution-based (GDB) approach to determine baseline mole fractions directly from global SF6 mole fraction fields at the termination points of the backward trajectories. We compute these fields by performing an atmospheric SF6 re-analysis, assimilating global SF6 observations into modelled global three-dimensional mole fraction fields. Our inversion results are in excellent agreement with several regional inversion studies in the USA, Europe, and China. We find that (1) annual US SF6 emissions strongly decreased from 1.25 Gg in 2005 to 0.48 Gg in 2021; however, they were on average twice as high as the reported emissions to the United Nations. (2) SF6 emissions from EU countries show an average decreasing trend of −0.006 Gg yr−1 during the period 2005 to 2021, including a substantial drop in 2018. This drop is likely a direct result of the EU's F-gas regulation 517/2014, which bans the use of SF6 for recycling magnesium die-casting alloys as of 2018 and requires leak detection systems for electrical switch gear. (3) Chinese annual emissions grew from 1.28 Gg in 2005 to 5.16 Gg in 2021, with a trend of 0.21 Gg yr−1, which is even higher than the average global total emission trend of 0.20 Gg yr−1. (4) National reports for the USA, Europe, and China all underestimated their SF6 emissions. (5) Our results indicate increasing emissions in poorly monitored areas (e.g. India, Africa, and South America); however, these results are uncertain due to weak observational constraints, highlighting the need for enhanced monitoring in these areas. (6) Global total SF6 emissions are comparable to estimates in previous studies but are sensitive to a priori estimates due to the low network sensitivity in poorly monitored regions. (7) Monthly inversions indicate that SF6 emissions in the Northern Hemisphere were on average higher in summer than in winter throughout the study period.
Crowd-sourced trait data can be used to delimit global biomes
Authors: Scheiter Simon , Wolf Sophie , Kattenborn Teja
Published: November 2024

Abstract. Terrestrial biomes and their biogeographic patterns have been derived from a large variety of variables including species distributions and bioclimate or remote sensing products. However, classifying the biosphere into biomes from a functional perspective using biophysical traits has rarely been tested. Such a trait-based biome classification has been limited by data availability. Here, we aimed to exploit crowd-sourced plant observations and trait databases to systematically assess which traits are most suitable for biome classification. We derived global patterns of 33 biophysical traits covering around 50 % of the land surface by combining crowd-sourced species distribution data from the Global Biodiversity Information Facility (GBIF) and trait observations from the TRY database. Using these trait maps as predictors for supervised cluster analyses, we tested to what extent we can reconstruct 31 published biome maps. A sensitivity analysis with randomly sampled combinations of traits was performed to identify the traits that are most appropriate for biome classification. Performance was quantified by comparing modeled biome maps and the respective observation-based biome maps. Finally, spatial gaps in the resulting biome maps were filled using species distribution models to obtain continuous global biome maps. We showed that traits can be used for biome classification and that the most appropriate traits are conduit density; rooting depth; height; and different leaf traits, including specific leaf area and leaf nitrogen content. The best performance of the biome classification was obtained for biome maps based on biogeographic zonation and species distributions, in contrast to biome maps derived from optical reflectance. The availability of crowd-sourced plant observations is heterogeneous, and, despite its exponential growth, large data gaps are prevalent. Nonetheless, it was possible to derive biome classification schemes from these data to predict global biome patterns with good agreement. Therefore, our analysis is a valuable approach towards understanding biome patterns based on biophysical traits and associated ecological strategies.

Authors: Bolkas Dimitrios , O’Banion Matthew , Parisi Erica Isabella , Bauer Peter , Detchev Ivan
Published: November 2024

Abstract. Immersive technologies are becoming a powerful tool for educators across multiple disciplines including geospatial science. They offer new ways to engage and educate geospatial students, removing barriers that may exist in traditional teaching methods. Especially because the limitations of 2D screens are often exceeded by the complexity of modern data sets. Examples of challenges that educators often encounter are explaining theoretical concepts in the classroom, providing alternate scenarios, preparing students for physical labs, and limited / restricted access to physical sites. Immersive technologies can be a great resource to support on-site lectures and enhance remote learning, a necessity in today's educational panorama. Immersive technologies typically include virtual, augmented, and mixed reality. Each method offers different pedagogical advantages and poses different challenges. Before any implementation, these advantages and challenges must be examined and understood to maximize the benefit of immersive methods to the students and mitigate potential drawbacks that could hinder learning outcomes. This paper provides a review of the different immersive methods, presenting examples of their application in geospatial education with lessons learned and recommendations for future work. The case examples include a variety of different instruments and tasks such as the simulation of GNSS, differential leveling, total station operations, and airborne LiDAR data collection.

Published: November 2024

Abstract. This paper presents a collaborative effort to develop localized solar photovoltaic (PV) power output (PPV) forecasting models for the Philippines using geospatial data. It underlines the importance of solar energy in the country and discusses the opportunities and challenges associated with PPV forecasting. Project SINAG, a two-year research project, aimed to develop solar PV output forecasting models through a collaborative approach with academic institutions, solar energy industries, and government agencies. Actual PPV data from 43 solar PV installations were analyzed alongside meteorological data from the PAGASA weather bureau, ERA5, AHI-8, and FY- 4A. These datasets were filtered based on a one-year period to ensure quality. The study employed SARIMAX, LSTM, and XGBoost models individually and in hybrid models to develop the forecasting models. Model performance was evaluated using root mean square error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE). In a case study in Baguio City, the SARIMAX model exhibited strong seasonal dependence, providing more accurate forecasts in dry seasons than in wet seasons. Additionally, the forecasting accuracy of each model (SARIMAX, LSTM, and XGBoost) varied based on the month and location of the installation, emphasizing the need for local and season-based PPV forecasting models. Despite implementation challenges, such as collaboration arrangements, bureaucratic barriers, and budget constraints, the project produced thirteen research publications and provided data for three student theses. This paper also demonstrated diverse engagements and contributions that emphasize the significance of collaborative research in conducting nationwide-scale data-driven projects.

Becoming Breadthrog: Role-playing games, metacognition and the creative writer
Authors: Wilcox Pierce , Marshall Helen
Published: November 2024

All fiction writers work with characters, and many deploy metaphors to describe this relationship: characters may be tools, friends or voices in the writer’s head. These are vivid images but unsuitable for understanding a past writer’s thought process or advising a future writer. This article takes a practical and cognitive approach to the writer-character relationship. We consider a writer’s approach to character as a form of problem-solving and use metacognitive science to understand why a writer chooses a particular level of immersion within a character and how they instinctively or strategically move between different cognitive and emotional frames. While literary and creative writing studies lack the precise language to describe these levels of immersion, a useful parallel exists in game studies. We draw on the sociology of role-playing games to understand and describe the relationship between the creator and the fictional character. Combining insights from game studies and metacognitive psychology, we propose a three-level model of the creative writer’s cognitive relationship with their fictional characters, ranging from full immersion to critical distance. Our model serves two purposes: its specific language can illuminate further studies of character writing and shape targeted interventions to assist creative writers struggling with questions of character.
Formas y límites del compromiso intelectual en el socialismo madrileño. El caso de Rafael García Ormaechea (1903-1909)
Authors: Núñez Rodríguez Alberto
Published: November 2024

Este artículo analiza la militancia socialista de Rafael García Ormaechea (1876-1938) entre 1903 y 1909. Además de contribuir al conocimiento de la biografía de García Ormaechea este estudio aborda la relevancia que tienen su etapa socialista para la comprensión de aspectos centrales de la cultura política socialista en la España del primer tercio del siglo XX. Su producción intelectual y su trayectoria política en la Agrupación Socialista Madrileña prueban cómo los intelectuales podían relacionarse, integrarse y desarrollar una carrera política exitosa en el Partido Socialista Obrero Español. El ascenso de Ormaechea entre los socialistas madrileños revela el valor que tenía la formación universitaria, con qué tipo de actividades se asociaba la militancia de un intelectual y la forma en que se les podía promocionar desde la dirección socialista. Su salida del partido, por el contrario, pone en evidencia las tensiones que provocaba este proceso, como se ha comprobado ya en otros casos y en los movimientos socialistas de otros países europeos. La hemeroteca y la documentación interna del PSOE constituyen las fuentes fundamentales de esta investigación, que hemos llevado a cabo mediante la metodología propia de la historia intelectual.
Hojas volantes por las calles de Milán: un episodio de la controversia jurisdiccional de finales del Quinientos
Authors: Rurale Flavio
Published: November 2024

Este trabajo profundiza en la conocida controversia jurisdiccional milanesa de los años 1596-1597, que condujo a la excomunión del jurista y hombre de gobierno Giacomo Menochio. En particular, se detiene en los instrumentos (carteles y folletos) que el protagonista de tal cuestión hizo imprimir y difundió por toda la ciudad en octubre de 1596, con el objetivo de informar a sus habitantes de lo que realmente había sucedido. El propósito de Menochio era demostrar la falsedad de las acusaciones vertidas contra su persona y recuperar así las relaciones sociales de las que había sido excluido, precisamente, a causa de su excomunión. Además, este ensayo pretende reflexionar sobre el tema historiográfico de la relación Estado-Iglesia a la luz de algunos debates que, en los últimos años, han hecho necesario cambiar el paradigma interpretativo.
“Questo titolo conosciuto da tutto il mondo per instrumento notabilissimo di tutte le discordie”. La strategia di Alfonso II d’Este e la Monarchia spagnola dinanzi all’elevazione dei Medici al titolo granducale negli anni Settanta del XVI secolo
Authors: Favalli Alessandra
Published: November 2024

La concessione del titolo di granduca di Toscana a Cosimo I de’ Medici da parte di Pio V nel 1569 acuì la conflittualità che contraddistingueva le relazioni tra questi attori politici e il duca di Ferrara, Alfonso II d’Este. Questi, colpito negativamente dal privilegio pontificio relativamente alla disputa per la precedenza che lo opponeva ai Medici, provò a sfruttare a proprio vantaggio le tensioni sorte nella penisola italiana conseguentemente alla creazione del granducato di Toscana per ottenere una presa di posizione del  re di Spagna a proprio favore e in opposizione al nuovo titolo. Questo studio si propone di analizzare la strategia retorica utilizzata dal duca di Ferrara per cercare di acquisire supporti alla corte di Spagna, le modalità attraverso le quali i suoi agenti furono chiamati a metterla in atto e i risultati ottenuti a fronte dell’evolversi della politica asburgica a beneficio dei Medici e a inevitabile detrimento delle ragioni estensi.
«La correspondencia con los que escriben la Historia destos tiempos»: la Monarquía española y la producción historiográfica entre Castilla e Italia (1630-1661)
Authors: Giannini Massimo Carlo
Published: November 2024

Este trabajo quiere analizar cómo los ministros de la Monarquía de Felipe IV se relacionaron con la escritura de libros de historia. La obsesión por la escritura de la historia - ampliamente compartida a nivel europeo - nacía del deseo de vigilar el flujo de información, tanto la difundida por avisos y gacetas, como por obras manuscritas e impresas, consideradas un importante vehículo de propaganda cultural y política. Al interés de los ministros de Felipe IV por el estudio del pasado no correspondió una inversión de recursos, tanto materiales como inmateriales, capaz de competir con la capacidad de la corte de Francia para establecer vínculos efectivos y sólidos con los historiadores italianos más exitosos de la época. En la imposibilidad de contar con autores de renombre, dispuestos a escribir sobre los acontecimientos recientes desde una perspectiva favorable a la Monarquía, los ministros del rey católico terminaron por intensificar las prácticas censoras en la Península Ibérica.
The Impact of Cognitive and Emotional Biases on Individual Investor’s Investment Decision: Mediating Role of Risk Perception
Authors: Malik Laraib , Ullah Kaleem , Soomro Mehwish
Published: November 2024

This study aims to clarify the mechanisms by which cognitive and emotional biases influence the investment choices of retail investors who trade on the Pakistan Stock Exchange (PSX), in addition to mediation of risk perception.  The behavior of retail investors in the least developing or emerging financial markets is not generally recognized, with most studies concentrating on well-developed financial markets. Utilizing a sample of 385 traders who are investors in the PSX, data was gathered through a purposive sampling technique. The descriptive analysis was conducted using IBM SPSS 27, while the measurement model and SEM assessments were conducted through SmartPLS 4.1.0.3. The findings reveal that biases, including representativeness bias (? = -0.185, p < .05), availability bias (? = -0.223, p < .000), and regret aversion bias (? = -0.494, p < .000), negatively affect investment choices made by retail investors on the PSX, with risk perception (? = 0.302, p < .000) mediating these relationships. This study, recommended for stock exchange investors and policymakers in collectivist cultures and least developed markets, provides original insights into the mediating role of risk perception, a context often overlooked in research focused on developed markets.

Authors: AbdulMalik Olalekan Oladipupo
Published: November 2024

In this study, the author focuses on how cryptocurrency and blockchain technology can be used to improve delivery of international aid since traditional methods include problems such as corruption, inefficiency and lack of transparency. The main research question addresses the question of how cryptocurrency could enhance efficiency, enhance transparency, accountability, and fight corruption in the dispensation of aid. The authors performed a qualitative content analysis of data collected from multiple articles, reports, and case studies including World Food Programme and United Nations Children's Fund(UNICEF).The study shows that blockchain’s distributed digital ledger minimizes misappropriation of funds risk, maintains real-time tracking; cryptocurrencies, specifically stablecoins, are more effective in real and low-cost transactions. Nevertheless, the work also points to the threats evident in legal and regulatory frameworks, low levels of digital literacy, and technological constraints. In conclusion, if all the challenges are solved, the cryptocurrency will enable the complete redesign of the distribution of the funds for aid.
The Role of Arbitration in Resolving Collective Labour Disputes: A Comparative Study of Public and Private Sectors
Authors: E. C. Ibekwe,
Published: November 2024

This paper aims at analysing how arbitration is used to solve collective labour relations by evaluating the application and results in both the public and the private sectors. This paper aims at assessing the effectiveness of arbitration as one of the ADR methods in dealing with disputes, in the two sectors. In the course of the study, the research compares arbitration with a view to identifying its effectiveness in sustaining industrial peace and reducing strikes. Employing a qualitative research design, data was collected from literature, case analyses and works from labour organisations. The results show that arbitration really works in both sectors, though the process is dependent on the legal and institutional frameworks. Arbitration is much more structured in the public sector because of legislation than it does in the private sector where flexibility results in swift outcomes. This paper concludes by identifying the policy significance of these findings for labour policy reform and exploring future research directions.
Addressing Gender Stereotyping in the Emergent World of Block-Chain and Cryptocurrency Administration
Authors: AbdulMalik Olalekan Oladipupo
Published: November 2024

The study seeks to address the gender gap in the crypto world by exploring strategies for promoting financial literacy, creating opportunities for women in the industry and addressing the “bro culture”. Several empirical evidence has been done by researchers which indicates that men are more interested in crypto currencies than women. This work will show how crypto currency-based approaches to development interact with gender, which are part of neoliberal beliefs about entrepreneurialism, financial inclusion, and gender roles. Block-chain technology has the potential to address gender inequality. The research methodology borders around the use of descriptive methods of analysis and content analysis. The work attempts to look into the rise of decentralized finance, specifically block chain-based applications and calls for a more feminine-friendly analysis. Findings by Gemini’s State of US Crypto report showed that women make up only 26% of the investors in the space. Forex analyzed the top 50 crypto company founders to find only 6% of these have female CEOs. The World Bank explores how block chain can be leveraged to advance gender equality, particularly in the context of humanitarian response and financial services. As such, the gender gap in the cryptocurrency world is a complex issue that requires a multifaceted approach to address. The study recommended that blockchain technology holds promise for promoting gender equality

Published: November 2024

Feral design aims to act as a transformative framework for design in the Anthropocene. This paper explores its potential to navigate the crises of modernity through a speculative deconstruction of three discrete case studies. Analysing said case studies of counter-culture movements’ operating at the fringes of the law reveals valuable insights into creativity, adaptability, and diffuse design capacity. The essence of feral design has been distilled into five principles, aiming to establish design methodologies. It calls for broader engagement from design researchers to expand the discourse and advance design practices in the Anthropocene. Feral design aims to act as a redirective practice that subverts modern design practice to enable its transition towards sustainment. By understanding the values embodied by different feral entities that respond to the collapse of traditional systems we can better understand how the principles of feral design can be embodied.

Published: November 2024

Grain products are a fundamental element in ensuring food security for the population. In recent years, the demand for whole grain products has significantly increased. Whole grain products are highly nutritious due to their balanced content of amino acids and other macro- and microelements. The aim of this study is to investigate the chemical and amino acid composition of whole grain raw materials such as triticale grain of the «Dauren» variety, buckwheat grain of the «Dikul» variety, and lentil grains of the «Sakura» and «Shyrayly» varieties. The chemical research revealed that whole leguminous crops have a high protein content, which is approximately twice as high as that of whole grains, with protein content values of 28,75% and 24,67%, respectively. The analysis of the conducted studies showed that the amino acid composition of the proteins in whole grains and whole leguminous crops is characterized by a high content of essential amino acids. Leguminous crops have a higher content of arginine and lysine compared to whole grains. Whole leguminous crops have a higher protein content than whole grains, making them important for increasing the nutritional value of food products when mixed. Additionally, various processing methods and their effects on preserving nutritional properties were studied.

Published: November 2024

In this study, cultures of lactic acid bacteria (3M, 3K, 7K, 9K, 10K and 11K) isolated from mare's milk and koumiss were examined in order to assess their resistance to various antibiotics. Discs impregnated with gentamicin (120 mcg), azithromycin (15 mcg), ceftriaxone (30 mcg), cefuroxime (30 mcg) and chloramphenicol (30 mcg) were used.

The data obtained showed that strains 3K, 10K and 11K demonstrated the greatest resistance to gentamicin, similarly, strains 10K and 11K showed high resistance to azithromycin. For ceftriaxone and cefuroxime, strains 11K and 10K demonstrated the greatest resistance. Strains 11K and 10K were the most resistant to chloramphenicol, while strain 3K was the most sensitive. In general, strains 3K and 3M showed the least resistance to most antibiotics, especially ceftriaxone and cefuroxime, which indicates their high sensitivity to these drugs. In contrast, strains 10K and 11K demonstrated the greatest resistance, showing minimal suppression zones for most of the antibiotics studied.

The obtained data can be used to develop and optimize probiotic drugs that take into account the resistance of lactic acid bacteria to antibiotics. This will increase the effectiveness of the use of probiotics in various foods and medicines, contributing to the maintenance of healthy intestinal microflora and strengthening the immune system.

Published: November 2024

Nowadays, the issues of ecology and sustainable development are becoming more and more urgent, and the scientific community is actively looking for ways to more efficient and environmentally friendly use of renewable energy sources. One of such directions is the development and improvement of coal combustion technologies in aerodynamic furnaces. This paper offers a detailed analysis of this topic, looking at both theoretical aspects and practical applications. Aerodynamic furnaces are specialised devices designed to burn solid fuels such as coal with maximum efficiency and minimum environmental impact. The basic principle of operation of such furnaces is to create optimum conditions for complete combustion of the fuel, which is achieved through carefully designed aerodynamics and process control. The operation of the boiler on the coal of Karazhyra deposit is considered. This coal belongs to non-project fuel and improvement of its combustion processes is required to reduce harmful emissions and increase combustion efficiency. For the energy sector of the Republic of Kazakhstan, the conducted research is important, and the results obtained can be used to regulate and improve the operation of similar equipment, which contributes to improving environmental performance and overall efficiency of the country's energy systems.

Published: November 2024

This study investigates the impact of flue gas recirculation on key parameters of the fuel combustion process, such as heat release and adiabatic combustion temperature. Based on the mathematical processing of experimental data, equations were obtained that reflect the dependence of useful heat release and adiabatic combustion temperature on the gas recirculation coefficient. According to the results of the study, the useful heat release in the furnace increases proportionally with the growth of the recirculation coefficient. This indicates that an increase in the level of recirculation contributes to an increase in combustion thermal efficiency, improving heat exchange processes within the furnace.

 A similar trend is observed for the adiabatic combustion temperature. It was found that the adiabatic combustion temperature also increases with an increase in the recirculation coefficient, which indicates the significant influence of recirculation on raising the temperature parameters of the combustion process. The rise in combustion temperature is associated with improved fuel combustion and more complete utilization of its energy potential. This, in turn, can contribute to a reduction in emissions of harmful substances such as nitrogen oxides and carbon, which is an important factor for environmental safety.

Thus, the results of the study demonstrate that flue gas recirculation has a significant impact on heat exchange processes and combustion temperature. This makes recirculation an effective tool for increasing thermal efficiency and reducing the environmental impact. The application of this method in modern energy systems not only improves production performance but also ensures compliance with environmental requirements. The study results confirm the feasibility of implementing flue gas recirculation to enhance overall efficiency and environmental safety in energy installations.

This study focuses on analysing the effectiveness of porous metals in heat exchangers, focusing on their effect on improving heat transfer processes. Porous metals, due to their unique structure, have high thermal conductivity and increased contact surface area, which contributes to more efficient heat transfer. As part of the study, experiments and theoretical analyses were carried out to evaluate the effect of porosity coefficient on heat exchange performance. The plotted dependence of Freon mass flow rate and heat quantity on porosity coefficient demonstrate the linear nature of these dependencies. Mathematical processing of the data showed that an increase in the porosity coefficient leads to an increase in both the amount of heat transferred by Freon and Freon mass flow rate, indicating an increase in heat exchange efficiency. The results confirmed that porous metals can significantly improve the performance of heat exchangers and energy saving. Based on the study, further investigation and implementation of porous metals in heat exchangers is recommended to optimise their performance and improve the overall system efficiency. These results open new perspectives for the application of porous metals in various industries including power and mechanical engineering.

Published: November 2024

This research offers an in-depth exploration of the impact of cathodic nitriding on the structural and mechanical characteristics of 45 steel treated in different aqueous electrolytes. Through a combination of Xray diffraction and electron microscopy analyses, it was determined that the nitriding process facilitates the development of a multilayered surface structure, which includes oxide, nitride, and martensitic layers. The composition of the electrolyte plays a crucial role in determining the phase composition and thickness of the modified layers, directly influencing the steel's mechanical properties, as reflected by variations in hardness and wear resistance post-treatment. Notably, an electrolyte containing sodium carbonate (Na₂CO₃) and urea (CH₄N₂O) achieved a maximum microhardness of 986 HV due to the formation of a dense nitride layer. On the other hand, introducing ammonium nitrate to the electrolyte, while slightly decreasing the microhardness to 882 HV, resulted in the formation of a more intricate and stable phase structure, including additional nitrides and oxides, which contributed to enhanced corrosion resistance. These findings underscore the critical importance of optimizing electrolyte composition to improve the performance characteristics of steel, such as hardness, wear resistance, and corrosion resistance. This study underscores the effectiveness of cathodic nitriding as a method for significantly enhancing the mechanical and surface properties of 45 steel, thereby expanding its potential for use in high-load and aggressive environments.
