Documenting Domination: From the Doctrine of Christian Discovery to Dominion Theology
Authors: Brett Adam , Hill (Lyons) Betty
Published: December 2024

The Doctrine of Christian Discovery is a series of fifteenth-century papal bulls that served as the theological and legal justification for the colonization of the world and the enslavement of the Original Free Nations, starting first on the African continent before spreading across the globe. In the 1800s, these bulls and other documents like The Requerimiento and colonial charters would be codified and enshrined together in U.S. law as the Doctrine of Christian Discovery, becoming the foundation of property law and international law. Also, considering what Peter d’Errico calls Federal Anti-Indian Law, we will trace and document how this framework of domination began with the Catholic crowns of Europe and transformed into the dominion theology found within Christian nationalist theologies today. Our research highlights how the Doctrine became enshrined and encoded within Protestantism and the imagined “secular” of the U.S. and Canada, countries who rhetorically espouse separation of church and state while justifying land theft, treaty violations, and the abuse of Indigenous nations and peoples through the Doctrine. We craft a genealogy of Christian domination by carefully analyzing primary sources, especially the colonial charters. We will conclude by juxtaposing the domination framework and the Haudenosaunee Confederacy’s principles of the Gayanashagowa (Great Law of Peace).
Theology Goes Public: Richard Shaull’s Dialogue with Public Issues, Social Sciences, and Ecumenism in “The New Revolutionary Mood in Latin America” (1962)
Authors: Zeferino Jefferson , von Sinner Rudolf
Published: December 2024

Since the arrival of Protestants in Brazil, the presence of Protestant educational institutions became a reality. Seminaries were founded at the end of the 19th century, focusing on the training of clergy without much concern for dialogue with other churches or with society at large. Public issues, ecumenism—through dialogue and cooperation between Protestants and Catholics—and interdisciplinary theological approaches only became current concerns in the mid-twentieth century, especially with liberation theologies—both Protestant and Catholic. Before that, however, one of the authors who was able to grasp these dimensions in his theological endeavour was Richard Shaull, who, through his theological method, opened a dialogue with the social sciences in order to interpret the reality in which he placed Christian action and mission. Through bibliographical research and document analysis, focusing on the reading of “The New Revolutionary Mood in Latin America”, a report on Latin America presented by Shaull to the National Council of the Churches of Christ in the U.S.A. Missionary Board, the article aims to show Shaull’s theology, institutionally located, as one that thinks about public issues in dialogue with social sciences and considers its implications for and within Christian churches. In the light of studies on public theology, this paper presents Richard Shaull’s writings as a theological approach to the church, considering its ecumenical stance; to society, considering its most pressing issues of the time; and to academia, through the interdisciplinary dialogue he undertakes with the social sciences.
Prisoners’ Opinions About Religious Practices in Polish Penitentiary Facilities: An Analysis of the Results of a Study
Authors: Sitarz Olga , Jaworska-Wieloch Anna , Hanc Jakub
Published: December 2024

Religious freedom and the right to practice a religion by persons deprived of their liberty do not cause controversy in democratic states. The challenge, not easily met, is to exercise guaranteed religious rights in penitentiary facilities. This study aimed to compare legal regulations and the level of protection of religious freedom that they impose with the real possibility of the voluntary performance of religious practices. In other words, this study sought to answer the question of whether prisoners in Polish penitentiary facilities are free to practise the religion of their choice and are not forced to participate in religious practices against their will. This article presents the general results of a survey on religious practices carried out in the Polish penitentiary facilities that were examined. The data were supplemented by prisoners’ comments about freedom to practice religion. This article includes the comments of both believers (assessing the availability of practices) and non-believers (assessing the compulsion to participate in the practices of the dominant religion). Opinions about practising a religion given by the penitentiary staff will serve as a specific counterpoint. The presented study results allowed the formulation of basic conclusions of a general nature, which can contribute to further discussions on religious freedom in post-criminal isolation units. The survey was carried out from March to October 2022 based on a prepared questionnaire. It was completed by 556 prisoners, including 34 females and 444 males (68 respondents did not indicate their gender). In total, prisoners incarcerated in 35 penitentiary facilities located throughout Poland were surveyed. Simultaneously, a survey was carried out among educators and teachers in all the above penitentiary facilities, who completed, in total, 164 questionnaires. An analysis of the replies to the questions and the free comments of all the respondents and their comparison with the current regulations make it possible to conclude that Poland—on a constitutional and statutory level—adequately safeguards prisoners’ religious rights, but their practical application must be assessed as unsatisfactory. Prisoners do not always have the possibility to observe rites or manifest their religion. Problems are encountered by both followers of the strongly dominant religion in Poland (Roman Catholicism) and minority denominations. Despite the reported difficulties, Roman Catholics are indisputably in a much more favourable position. Freedom from religion is also not fully respected—prisoners involuntarily participate in certain practices and take part in the religious observance of church festivals.
The Religious Dimension of Mencius’ Theory of the Goodness of Human Nature: A Critique of Gaozi’s View
Authors: Cai Tianyang , Chen Yun
Published: December 2024

This paper argues that the Confucian notion of the “goodness of human nature” (Xing Shan 性善) does not exclude a religious dimension by examining Mencius’ explanation of this theory. In his response to Gongduzi (公都子), Mencius articulates his understanding of the goodness of human nature. Combining this response with Mencius’ criticism of Gaozi, the two discussions can illuminate each other. Mencius opposes Gaozi’s approach that relies on facts (Qing 情) and talents (Cai才) to define human nature. He argues that such an approach stems from an inductive mode of cognition and a detached observer’s stance toward the world, leading to a perspective devoid of a spiritual world. In contrast, Mencius posits that individuals, beyond sensory perception, can use the faculty bestowed by Heaven to perceive a world infused with noble spirit (Hao Ran Zhi Qi 浩然之氣). The heart-mind, deriving from a transcendent Heaven (天), holds religious significance for Mencius and represents an entity we must serve. However, this does not mean abandoning moral life. On the contrary, Mencius asserts that serving Heaven involves facing moral situations directly, discerning righteousness, and anchoring the direction of one’s actions. In realizing oneself, one also contributes to the realization of others, a significant interpretation of “human nature” as Mencius conceives it. By integrating religious belief with secular life, Mencius grounds the latter in the former, imbuing Confucian thought on the goodness of human nature with an implicit reverence. This approach invites us to understand human life within the comprehensive connection with the universe.

Published: December 2024

Background and Clinical Significance: Femoral neck fracture frequently occurs in the elderly population but may also present in patients diagnosed with primary cancer or bone metastases. A pathological, oligosymptomatic fracture associated with epithelioid haemangioendothelioma (EHE), a rare endothelial cell-derived sarcoma, is uncommon. Case Presentation: A 44-year-old patient underwent biopsy procedures three times (2010, 2012, 2013) for a focal lesion of the left ischium, none confirming its malignant nature. The last biopsy revealed a neoplastic tissue with features of discrete dysplasia. The lesion did not undergo medical follow-up for seven consecutive years. In August 2020, the patient presented with right lower limb pain. A CT scan, PET/CT scan, and biopsy confirmed EHE with spindle/sarcomatous features. In November 2020, chemotherapy (5xADIC) started (PET/CT confirmed a partial response). After its completion in July 2021, bone progression occurred and sirolimus-based therapy was started. After 3 months, a small liver metastasis was visualized on PET/CT, which did not result in the termination of treatment. In December 2021, pamidronate-based antiresorptive therapy was started. Liver metastasis remained stable in follow-up CT scans. Due to pelvic and spinal lesions, the patient was assisted by elbow crutches and underwent radiotherapy, remaining professionally active. The patient did not report any trauma, but in August 2023, a subsequent CT scan revealed a subcapital fracture of the left femoral neck in the fusion phase. Due to pelvic changes and the stable nature of the fracture, surgical treatment was abandoned. Conclusions: An oligosymptomatic femoral neck fracture, not requiring medical intervention is considered a rare complication of bone cancer.
CNN-Based Multi-Object Detection and Segmentation in 3D LiDAR Data for Dynamic Industrial Environments
Authors: Schneider  Danilo , Stemmer Marcelo
Published: December 2024

Autonomous navigation in dynamic environments presents a significant challenge for mobile robotic systems. This paper proposes a novel approach utilizing Convolutional Neural Networks (CNNs) for multi-object detection in 3D space and 2D segmentation using bird’s eye view (BEV) maps derived from 3D Light Detection and Ranging (LiDAR) data. Our method aims to enable mobile robots to localize movable objects and their occupancy, which is crucial for safe and efficient navigation. To address the scarcity of labeled real-world datasets, a synthetic dataset based on a simulation environment is generated to train and evaluate our model. Additionally, we employ a subset of the NVIDIA r2b dataset for evaluation in the real world. Furthermore, we integrate our CNN-based detection and segmentation model into a Robot Operating System 2 (ROS2) framework, facilitating communication between mobile robots and a centralized node for data aggregation and map creation. Our experimental results demonstrate promising performance, showcasing the potential applicability of our approach in future assembly systems. While further validation with real-world data is warranted, our work contributes to advancing perception systems by proposing a solution for multi-source, multi-object tracking and mapping.

Published: December 2024

Hyperspectral remote sensing images offer a unique opportunity to quickly monitor water depth, but how to utilize the enriched spectral information and improve its spatial resolution remains a challenge. We proposed a water depth estimation framework to improve spatial resolution using deep learning and four inversion methods and verified the effectiveness of different super resolution and inversion methods in three waterbodies based on HJ-2 hyperspectral images. Results indicated that it was feasible to use HJ-2 hyperspectral images with a higher spatial resolution via super resolution methods to estimate water depth. Deep learning improves the spatial resolution of hyperspectral images from 48 m to 24 m and shows less information loss with peak signal-to-noise ratio (PSNR), structural similarity (SSIM), and spectral angle mapper (SAM) values of approximately 37, 0.92, and 2.42, respectively. Among four inversion methods, the multilayer perceptron demonstrates superior performance for the water reservoir, achieving the mean absolute error (MAE) and the mean absolute percentage error (MAPE) of 1.292 m and 22.188%, respectively. For two rivers, the random forest model proves to be the best model, with an MAE of 0.750 m and an MAPE of 10.806%. The proposed method can be used for water depth estimation of different water bodies and can improve the spatial resolution of water depth mapping, providing refined technical support for water environment management and protection.

The Tarim River Basin (TRB) faces significant ecological challenges due to global warming, making it essential to understand the changes in the climates of its sub-basins for effective management. With this aim, data from national meteorological stations, ERA5_Land, and climate indices from 1961 to 2021 were used to analyze the temperature and precipitation variations in the TRB and its sub-basins and to assess their climate sensitivity. Our results showed that (1) the annual mean temperature increased by 0.2 °C/10a and precipitation increased by 7.1 mm/10a between 1961 and 2021. Moreover, precipitation trends varied significantly among the sub-basins, with that in the Aksu River Basin increasing the most (12.9 mm/10a) and that in the Cherchen River Basin increasing the least (1.9 mm/10a). Moreover, ERA5_Land data accurately reproduced the spatiotemporal patterns of temperature (correlation 0.92) and precipitation (correlation 0.72) in the TRB. (2) Empirical Orthogonal Function analysis identified the northern sections of the Kaidu, Weigan, and Yerqiang river basins as centers of temperature sensitivity and the western part of the Kaidu and Cherchen River Basin as the center of precipitation sensitivity. (3) Global warming is closely correlated with sub-basin temperature (correlation above 0.5) but weakly correlated with precipitation (correlation 0.2~0.5). TRB temperatures were found to have a positive correlation with AMO, especially in the Hotan, Kashgar, and Aksu river basins, and a negative correlation with AO and NAO, particularly in the Keriya and Hotan river basins. Precipitation correlations between the climate indices were complex and varied across the different basins.

Published: December 2024

The present work describes, for the first time, an eco-friendly capillary zone electrophoresis (CZE) methodology for determining apixaban (APX), an oral anticoagulant. Separation was carried out using a fused silica capillary with an applied voltage of 20 kV and hydrodynamic injection for 5 s at 50 mbar. The electrolyte system consisted of 50 mM sodium borate at pH 8.0. The method was validated as recommended by ICH, establishing selectivity, linearity, precision, accuracy, and robustness. The analytical procedure was linear in the range of 10–125 µg mL−1 (r = 0.999). The limits of detection and quantification were determined to be 1.77 µg mL−1 and 5.37 µg mL−1, respectively. Precision was evaluated by relative standard deviation (RSD), with an intra-day RSD (n = 6) of 0.96% and an inter-day RSD (n = 18) of 4.42%. The average recovery rates for the pharmaceutical samples were excellent, ranging from 98.03% to 101.01%, with an RSD of 1.51%. Moreover, the green profile of the method was evaluated using the National Environmental Methods Index (NEMI), Analytical Eco-Scale, Green Analytical Procedure Index (GAPI), and Analytical GREEnness Metric (AGREE) assessment tools. The results suggest that the CZE method aligns with the principles of green chemistry, offering a greener alternative for the routine analysis of APX quality control. Also, the method presents a low-cost analysis, using fewer organic solvents and minimizing waste generation compared to techniques commonly used in routine analysis.

Doping engineering has been applied in niobium-doped NiO (NiO:Nb) by adding nitrogen (N) in its structure. The rf-sputtered films were made from a Ni-Nb composite target on unheated substrates at 300 W rf power and 5 mTorr total pressure. The plasma contained 50% Ar and 50% O2 for the fabrication of the single-doped NiO:Nb film (AΝ film), and N2 gas for the incorporation of N in the Ni-O-Nb structure. The N2 in plasma was introduced by keeping constant the flow rates of O2 and N2 gasses (O2/N2 = 1) and reducing the amount of Ar gas, namely 94% Ar, 3% O2, and 3% N2 (film AN1); 50% Ar, 25% O2, and 25% N2 (film AN2); and 6% Ar, 47% O2, and 47% N2 (film AN3). All films had the single phase of cubic NiO and both Nb and N in the Ni-O structure were revealed by XPS experiments. The roughness of the films was increased with the increase in N in plasma. Post-deposition thermal treatment improved the crystallinity and reduced the structural disorder of the films. The AN2 film was found to be the most transparent of all films, exhibiting the widest band gap, 3.72 eV, and the narrowest Urbach tail states’ width, 313 meV. The AN and the AN2 films were employed to form NiO/TiO2 heterostructures. The NiO:Nb/TiO2 and NiO:(Nb,N)/TiO2 heterostructures exhibited a visible transmittance of around 42% and 75%, respectively, and both showed rectification properties. Upon illumination with UV light, the NiO:(Nb,N)/TiO2 diode exhibited enhanced photovoltaic performance when compared to the NiO:Nb/TiO2 solar cell: the short-circuit current densities were 0.2 mA/cm2 versus 1.4 μA/cm2 and the open-circuit voltages were 0.5 V versus 0.2 V. The output characteristics of the p-NiO:(Nb,N)/n-TiO2 UV photovoltaics can be further improved by proper engineering of the individual layers and device processing procedures.

The aim of this study was to examine the differences in match running performance (MRP) according to the ambient temperature during UEFA Champions League (UCL) matches. Data were collected using an optical tracking system from all teams (n = 32) in all UCL matches (n = 125) during the 2022/23 season, and classified according to the ambient temperature at which matches were played: <5 °C, 6–10 °C, 11–20 °C, and >21 °C. The results revealed the following: (i) less total distance was covered in matches played at ≥21 °C compared to the matches played at 6–10 °C (d = 0.58), (ii) less high-speed running and high-intensity running were covered in matches played at ≥21 °C compared to the matches played at 11–20 °C (d = 0.54 and 0.43, respectively), 6–10 °C (d = 0.89 and 0.8, respectively), and ≤5 °C (d = 0.62 and 0.57, respectively), and (iii) less sprinting was covered in matches played at ≥21 °C compared to the matches played at 6–10 °C (d = 0.22). These findings indicated the significant differences in MRP when UCL matches were played at different ambient temperatures, with notable reductions in overall and high-intensity efforts in warmer conditions.

Authors: Yadav Anita , Anwer Naqui , Mahapatra Krushna , Shrivastava Manish Kumar , Khatiwada Dilip
Published: December 2024

In the face of climate change, urban governance systems must adapt to uncertainties and emerging pressures. Polycentric governance, characterized by multiple decision-making centers at different scales, enables coordination across levels and provides flexibility, which allows for experimentation and context-specific action, catalyzing institutional innovations in cities. These innovations involve creating new structures and modifying existing ones to help cities better withstand and adapt to the impacts of climate change. There are plenty of studies on this issue in developed country context, but such studies in the context of developing countries are lacking, especially in India. This article aims to explore the influence of polycentric governance on institutional innovations, thereby offering insights on how it contributes to transformative urban governance in India, characterized by (1) stewarding capacity, (2) unlocking capacity, (3) transformative capacity, and (4) orchestrating capacity. The research findings suggest that polycentric governance increases diversity and autonomy in decision-making centers across levels, which can enable more innovation or flexibility, leading to improving governance capacity to respond to changing circumstances, but these developments are still in nascent stage and further research is needed to assess the long-term sustainability of these capacities. The findings not only contribute to governance research and provide insights for policymaking, but also contribute to the broader discourse on urban resilience and sustainable development aligning with SDG 11 (sustainable cities and communities) and SDG 17 (partnerships for the goals) globally, especially in the Global South.
A Comprehensive Evaluation of Water-Saving Society Construction in Xinxiang, Henan Province, China
Authors: Jiang Mingliang , Zhang Chengcai
Published: December 2024

Water is a crucial and fundamental resource. It is well known that agricultural cultivation, industrial production, and human daily life are not possible without water. Efficiently utilizing water resources is of great significance for achieving global Sustainable Development Goals (SDGs). In order to improve water use efficiency in various industries and promote water-saving development, China has been implementing water-saving society construction since 2002. Henan Province is the main grain-producing area in China, with wheat production accounting for a quarter of the country’s total. As the core area of “Central Plains Agricultural Valley” in Henan Province, Xinxiang City plays an important role in agricultural technology innovation and agricultural production. However, Xinxiang City is facing problems of water scarcity and pollution, which constrain the sustainability of agricultural production. Therefore, building a water-saving society can solve the current water problems faced by Xinxiang City and ensure the sustainable development of the economy and society. This study built an evaluation index system for water-saving society construction in Xinxiang, Henan Province, China. The proposed evaluation index system includes 20 evaluation indices from six aspects—integrated, agricultural water, industrial water, domestic water, water ecology and environment, and water-saving management—and then divides its development level into several stages. The Analytical Hierarchy Process (AHP) was adopted to calculate the index weight. Then, a comprehensive evaluation model for water-saving society construction in Xinxiang City was established by combining it with grey relative analysis (GRA). The results showed that the overall level of water-saving society construction in Xinxiang City is in the excellent stage, whereas water consumption per CNY 10,000 of GDP, the effective utilization coefficient of irrigation water, the reuse rate of industrial water, and the leakage rate of urban water supply network are all in the good stage. However, the urban recycled water utilization rate is still in the poor stage. These research results can effectively and reasonably reflect the development level of water-saving society construction in Xinxiang City and guide the continued implementation of water-saving society construction. At the same time, the comprehensive evaluation of water-saving society construction helps to formulate and adjust water resource management policies and measures; it also holds significant value for sustainable water management and combating water scarcity.

Aguama (Bromelia pinguin L.), a plant belonging to the Bromeliaceae family, possesses a rich content of organic compounds historically employed in traditional medicine. This research focuses on the sustainable synthesis of ZnO nanoparticles via an eco-friendly route using 1, 2, and 4% of Aguama peel extract. This method contributes to environmental sustainability by reducing the use of hazardous chemicals in nanoparticle production. The optical properties, including the band gap, were determined using the TAUC model through Ultraviolet–Visible Spectroscopy (UV–Vis). The photocatalytic activity was evaluated using three widely studied organic dyes (methylene blue, methyl orange, and rhodamine B) under both solar and UV radiation. The results demonstrated that the ZnO nanoparticles, characterized by a wurtzite-type crystalline structure and particle sizes ranging from 68 to 76 nm, exhibited high thermal stability and band gap values between 2.60 and 2.91 eV. These nanoparticles successfully degraded the dyes completely, with methylene blue degrading in 40 min, methyl orange in 70 min, and rhodamine B in 90 min. This study underscores the potential of Bromelia pinguin L. extract in advancing sustainable nanoparticle synthesis and its application in environmental remediation through efficient photocatalysis.

Transport Sector Emissions and Environmental Sustainability: Empirical Evidence from GCC Economies
Authors: Binsuwadan Jawaher
Published: December 2024

This paper analyses the asymmetric effects of air transport on CO2 emissions from transport in the Gulf Cooperation Council countries. The analysis utilises CO2 emissions from transport, which are more relevant and critical for assessing the environmental performance of transport. Moreover, the current paper has examined this relationship with further macroeconomic variables within the Gulf Cooperation Council context. This paper uses a significant sample of six nations and spans an extensive period from 1990 to 2020. The second-generation Auto Regressive Distributed Lag model was applied to enable the examination of regional heterogeneity and the assessment of transport’s effect on CO2 emissions across several countries. The intensity of environmental degradation may differ among the Gulf Cooperation Council countries, hence, environmental policies should include trends in transport emissions. Long-term estimates based on the ARDL technique suggest that energy consumption, economic growth, and air travel exacerbate the ratio of CO2 emissions from transport and pollution levels. The results can be utilised to develop a transport-related environmental strategy that aligns with the sustainable development goals. The paper proposes strategies for achieving a sustainable environment and energy future.
Combination of Biochar and Advanced Oxidation Processes for the Sustainable Elimination of Pharmaceuticals in Water
Authors: Gallego-Ramírez Carolina , Chica Edwin , Rubio-Clemente Ainhoa
Published: December 2024

The presence of pharmaceuticals in aquatic ecosystems is an issue of increasing concern. Regardless of the low concentration of pharmaceuticals in water, they can have a toxic effect on both humans and aquatic organisms. Advanced oxidation processes (AOPs) have been described as a promising technique for eliminating pharmaceuticals due to their high efficiency. However, the cost associated with the application of these processes and their high reagents and energy requirements have affected the implementation of AOPs at large scales. Biochar has been suggested to be used as a catalyst in AOPs to overcome these limitations. Biochar is considered as an alternative heterogeneous catalyst thanks to its physicochemical characteristics like its specific surface area, porous structure, oxygen-containing functional groups, electrical conductivity, persistent free radicals (PFRs), modifiable properties, and structure defects. This carbonaceous material presents the capacity to activate oxidizing agents leading to the formation of radical species, which are needed to degrade pharmaceuticals. Additionally, AOP/biochar systems can destroy pharmaceutical molecules following a non-radical pathway. To enhance biochar catalytic performance, modifications have been suggested such as iron (Fe) impregnation, heteroatom doping, and supporting semiconductors on the biochar surface. Although biochar has been efficiently used in combination with several AOPs for the mineralization of pharmaceuticals from water, further research must be conducted to evaluate different regeneration techniques to increase biochar’s sustainable applicability and reduce the operational cost of the combined process. Moreover, operational conditions influencing the combined system are required to be evaluated to discern their effect and find conditions that maximize the degradation of pharmaceuticals by AOP/biochar systems.

Published: December 2024

Carbon dioxide (CO2) emissions are a significant global environmental concern, widely notable as a major cause of climate change. Meanwhile, transportation is the main sector contributing to CO2 emissions, which are escalating at a faster rate than Gross Domestic Product Growth. This study attempted to evaluate the spatial–temporal pattern of CO2 emissions from vehicles using the Sentinel 5P satellite image. The Sentinel 5P image was acquired from the European Space Agency from 2019 until 2022. Utilizing ArcGIS 10.5, these data were analyzed to extract the CO2 values, which were then displayed as the total column amount. Thereafter, the extraction by point method was conducted on road features based on the Mukim Kajang basemap to obtain the value of CO2 emissions from transportation. Spatial–temporal mapping was then accomplished through kernel density analysis, enabling the identification of CO2 emission hotspot areas. The findings show that the spatial–temporal pattern of CO2 emissions was higher in September 2019 (0.06964 mol/m2), March 2020 (0.03596 mol/m2), December 2021 (0.0437 mol/m2), and January (0.03384 mol/m2), respectively. Based on eight cities in Mukim Kajang, Bandar Kajang has been a hotspot area for carbon dioxide emissions from motor vehicles for four consecutive years, starting in 2019 until 2022. In summary, the results of this study could provide guidelines to researchers and policymakers to develop effective strategies to reduce the level of CO2 emissions from transportation in urban areas.

Published: December 2024

Renewable energy systems have emerged as a crucial research area due to the escalating demand for sustainable energy solutions. With the advancement of renewable energy, the electric-thermal coupling within multi-energy systems has become more intricate. Bi-directional electric-thermal storage and conversion technologies have emerged as a potential solution to address the challenges associated with efficient energy utilization. This paper focuses on the joint planning and operation optimization of renewable energy systems considering bi-directional electric-thermal storage and conversion. The integrated framework for renewable energy systems incorporating a bi-directional electric-thermal storage and conversion unit is designed, and the joint planning and operation optimization method is proposed.

Published: December 2024

In the delicate context of climate change and global warming, new technologies are being investigated in order to reduce pollution. The SOFC stands out as one of the most promising fuel cell technologies for directly converting chemical energy into electrical energy, with the added benefit of potential integration into co-generation systems due to its high-temperature waste heat. They also offer multi-fuel flexibility, being able to operate on hydrogen, carbon monoxide, methane, and more. Additionally, they could contribute to carbon sequestration efforts and, when paired with a GT, achieve the highest efficiency in electricity generation for power plants. However, their development is still challenged by issues related to high-temperature materials, the design of cost-effective materials and manufacturing processes, and the optimization of efficient plant designs. To better understand SOFC operation, numerous mathematical models have been developed to solve transport equations coupled with electrochemical processes for three primary configurations: tubular, planar, and monolithic. These models capture reaction kinetics, including internal reforming chemistry. Recent advancements in modeling have significantly improved the design and performance of SOFCs, leading to a sharp rise in research contributions. This paper aims to provide a comprehensive review of the current state of SOFC modeling, highlighting key challenges that remain unresolved for further investigation by researchers.
Using Existing Indicators to Bridge the Exposure Data Gap: A Novel Natural Hazard Assessment

Extreme natural hazard events are increasing across the globe, compelling increased climate research on resiliency. Research concerning issues as integrative as climate change and natural hazard resiliency often requires complex methodologies to account for cumulative influences. Indicators can be used to parse complex data to assess the intersection of inputs and outcomes (i.e., cumulative impacts). The Climate Resilience Screening Index (CRSI) is a good example of an indicator framework as it integrates indicators and their associated metrics into five domains (e.g., natural environment, society, and risk), enabling the index to accommodate a variety of inputs in its assessment of resilience. Indicator research, however, is generally limited by the availability of pertinent data. Natural hazard data concerning exposure, loss, and risk are routinely collected by the Federal Emergency Management Agency (FEMA) to create and update the National Risk Index (NRI), a composite index. The NRI can be disaggregated to obtain individual underlying metrics about natural hazard exposure. Quantifying natural hazard exposure requires extensive computation, with each hazard type requiring multiple modifying considerations, such as meteorological adjustments made by subject matter experts. Commonly available natural hazard exposure data, like that from FEMA, combines the spatial extent of historical natural hazard events and the determined value of the affected area. Exposure-related data were retrieved from the National Risk Index and used to create a new composite value to represent only the spatial extent of natural hazard events. Utilizing this new methodology to represent natural hazard exposure alleviates the burden of complex computation. It allows exposure data to be more expeditiously integrated into research and indices relating to natural hazards.

The increasing integration of sustainable energy sources, such as wind and solar power, into the national electricity grid presents significant challenges in terms of frequency control and grid stability. Additionally, the imbalance between electricity supply and demand introduces dynamic frequency variations. However, according to the literature, the impact of high penetration of renewable energy sources on the Tunisian grid has not been extensively analyzed using power system simulator for engineering (PSS/E). This research paper explores how the primary reserve technique participates to maintain frequency within acceptable ranges in the Tunisian electrical grid. Individual generators contribute to the total power output, thereby influencing frequency deviation. The primary frequency control action by each generator is proportional to its frequency deviation and inversely proportional to its governing drop, which measures the generator’s sensitivity to frequency changes. This paper analyzes frequency stability in the Tunisian grid under scenarios with and without different rates of sustainable energy source penetration, which barely reached 3.5% in 2023. In Tunisia, the use of sustainable energy is essential not only for ensuring grid stability but for combating climate change and reducing carbon emissions, aligning with the country’s environmental goals. The transition to sustainable energy significantly reduces the carbon footprint of the power sector, offering a sustainable solution for mitigating the adverse effects of climate change. Dynamic simulations were conducted for the isolated Tunisian system, separate from the interconnected grid, focusing on the critical scenario of the loss of a large electricity production unit. This study also examined the absence of sustainable energy integration and the effects of integration of different rates of renewable energy to evaluate the impact of reserves on the continuity of the Tunisian electrical service. Simulation results, which considered a 2023 grid model, show that with an integration trial of 20% renewable energy and, in the worst-case scenario, which represents the loss of the largest production group in the grid, the primary reserve of a given group—defined by the quantity of active energy—can be rapidly deployed to restore the balance between electricity supply and demand. Thus, reserves are a crucial solution for maintaining frequency within reasonable limits and ensuring the continuity of electrical services in Tunisia with varying rates from 10% to 20% integration of different sustainable energy sources.

Published: December 2024

The global COVID-19 pandemic has resulted in significant and accelerated developments in ventilation practises, where the need to ventilate buildings has been put centre stage. Longer-term ventilation approaches are now more likely to utilise hybrid ventilation strategies to address the challenge of ensuring resilient indoor thermal environments that are carbon neutral while also minimising the risk of long-range airborne infectious spread of viral pathogens. In the short term, there are many existing buildings which may not undergo retrofit for some time, and consequently, risk mitigation strategies have been implemented in these buildings by utilising existing systems. This paper will present an indoor environmental quality evaluation of ten university lecture rooms both before, during and after changes in ventilation management behaviour and systems that were accelerated due to the COVID-19 pandemic. The results indicate a mean reduction in internal carbon dioxide levels of between 46% and 67% when pre-COVID-19 and COVID-19 datasets are compared and between 11% and 62% when pre-COVID-19 and post-COVID-19 datasets are compared. Changes in behaviour and systems have reduced the time spent above thresholds conducive to virus growth by between 8% and 54%, depending on the lecture room. Despite this, a “rebound” can be observed in many rooms, with CO2 levels appearing to be trending toward pre-pandemic levels. This work indicates the effect of behavioural and system changes on ventilation and the potential risk for virus spread. The results indicate a need to retrofit existing lecture rooms with more advanced natural or mechanical systems to ensure consistent indoor environmental quality.

Nowadays, effective thermal management is essential to prevent overheating in high-power devices. The utilization of high-emissivity materials plays a crucial role in enhancing heat transfer efficiency in both natural and mixed convection systems. This study presents an experimental investigation of a rectangular fin heat sink’s thermal performance, exploring the effect of mixed convection and radiation heat transfer on two symmetrical fins with an aspect ratio of S*= 0.4 and 0.8. The experiment was carried out in a laboratory-scale wind tunnel, where the inlet fluid velocity was maintained at a constant value of u = 0.3 m/s across a range of Richardson number (0.6–5) and Rayleigh number (1.09–9.15 ×105), corresponding to the variation of heat loads 18–100 W. High-emissivity paint (ε = 0.85) was applied to the heat sink fins and compared to a low-emissivity paint (ε = 0.05) to assess the effect of performance. The results reveal that the high emissivity fin dissipated heat more effectively, with radiation and convection contributing approximately 25% and 75%, respectively, at the highest Rayleigh number. The study also revealed that increased fin spacing enhanced the view factor, although radiation heat transfer was higher for lower fin spacing due to a greater number of fins. Additionally, fin effectiveness was influenced more by fin spacing compared to surface emissivity, with effectiveness decreasing at higher Rayleigh numbers across all conditions. Infrared (IR) imaging confirmed that the high-emissivity coating allowed the heat sink to dissipate up to 30 °C from the heated surface, underscoring the substantial impact of high-emissivity materials in thermal management applications.
