Using Mercury Transformative Digestive Microbes for Wastewater, Soil and Dental Applications
type: item
description: the Environment through Diverse Pathways, including combustion, Industrial and mining effluents, septic discharge, and dental procedural waste. It may appear as elemental mercury (Hg0), inorganic mercuric compounds (Hg2), or organic mercury compounds such as methylmercury (MeHg). Although potentially hazardous in all forms, methylmercury poses the greatest concern due to its extreme neurotoxicity, high solubility, and ability to bioaccumulate within the food chain. This neurotoxin can cause a spectrum of adverse health effects, from subtle neurodevelopmental disorders to severe neurological impairments. Moreover, methylmercury exhibits significant environmental mobility, traversing from atmospheric and terrestrial systems into aquatic ecosystems, where it bioaccumulates and biomagnifies from plankton to fish, impacting human and wildlife health. In terrestrial environments, methylmercury can contaminate soil, disrupting beneficial microbial communities and entering the food web through agricultural products intended for human and animal consumption. In nature, mercury compounds interact with microbes in several ways. Certain microbes methylate Hg0 into MeHg, which increases environmental toxicity. However, most microbes are adversely affected by mercury ions as they disrupt cellular functions by binding to essential biomolecules. Mercury is particularly detrimental to a microbe’s ability to produce protease, an enzyme crucial for breaking down proteins into amino acids. Protease plays a significant role commercially in wastewater treatment, vacuum system maintenance, animal nutrition, soil health, and agricultural applications. Many commercial processes depend on non-denuded proteases for protein degradation. When microbes are utilized to produce protease for commercial applications, the presence of mercury in any form other than Hg0 can potentially diminish their functionality through protease disruption. Although not only the microbe’s ability to create and releas…

Trials of Christian Martyrs. Case Study: De Perpetuae et Felicitatis Martyrio
type: item
description: A person who dies for his religious faith is called a martyr or a martyr, but the term martyr also applies to those who give their lives for another cause, considered noble, such as those who die for their country in wartime. Martyrdom is the suffering, torment, torture, or death endured by someone for his ideas or beliefs. The term martyr is used by extension and in other forms, martyr of the fatherland, martyr of work, to honor specially performed acts of heroism. The word “martyr” is of Greek origin and denotes someone who confessed Christ by his own death. In the first phase, the title of martyr was used with reference to the apostles while they were still alive, then it was extended to all those who demonstrated faith, and finally it was used for those who died as a result of persecution.

Sustainable Peatland Management in Oil Palm Plantation: Challengingbut Manageable
type: item
description: The rapid expansion of oil palm plantations across tropical peatlands in Southeast Asia has intensified environmental degradation, including peat subsidence, CO₂ emissions, and recurrent fires. These issues have triggered growing academic and policy interest in sustainable peatland management, especially given the ecological fragility and socio-political complexity of plantation landscapes. This study aims to systematically synthesize scholarly evidence on the effectiveness, limitations, and interconnections of current sustainability strategies in hydrological control, fire prevention, land use planning, governance, and community engagement. This research employs a qualitative Systematic Literature Review (SLR) approach, guided by the PRISMA protocol. Data were collected through structured searches in the ScienceDirect database using targeted Boolean keywords. A total of 36 peerreviewed articles published between 2019 and 2025 were selected based on thematic relevance, open-access availability, and methodological rigor. All references were organized using Mendeley Desktop to ensure traceability and citation integrity. Data analysis involved thematic coding and content interpretation to identify cross-cutting patterns and strategic interactions. The results highlight that integrated water table control, participatory fire mitigation, context-sensitive spatial planning, and inclusive governance frameworks are essential pillars of sustainable peatland systems. However, gaps persist in enforcement capacity, cross-sectoral coordination, and long-term community incentives. In conclusion, sustainability in peat-based oil palm landscapes is attainable through multi-level alignment of ecological, technical, and institutional strategies. Future studies should explore the scalability of locally adapted interventions and long-term monitoring frameworks across diverse peatland geographies.

Enabling the Circular-Bioeconomy through Palm Oil Biomass: AReview of Industrial Innovations, Policy Frameworks, and MarketIntegration
type: item
description: The transition toward a circular-bioeconomy has positioned palm oil biomass as a pivotal renewable resource for achieving sustainable industrial transformation and low-carbon development. Yet, realizing this transition requires a systemic understanding of how technological, institutional, and market mechanisms interact to enable circularity across the palm oil value chain. This study aims to (1) synthesize technological and industrial innovation pathways driving palm biomass valorisation; (2) analyze the role of policy and governance instruments in supporting sustainable market integration; and (3) identify critical gaps and opportunities for advancing circular-bioeconomic transitions in the palm oil sector. Using a Systematic Literature Review (SLR) approach, data were systematically collected from the Scopus database through a multi-stage keyword refinement process. The initial query (Palm Oil AND Circular Economy) yielded 231 results, refined through specific terms related to biomass valorisation, innovation, and sustainability. Following the exclusion of irrelevant items, the restriction to publications from 2021–2025, and the restriction to open-access and open-archive sources, 38 peer-reviewed articles were retained for qualitative synthesis. Analytical procedures involved thematic coding and comparative interpretation to map interdisciplinary linkages among technological, institutional, and market domains. Findings reveal that integrated biorefinery technologies, digital traceability platforms, and AI-assisted optimization systems enhance resource efficiency and industrial circularity. However, fragmented regulatory frameworks, limited infrastructure, and investment asymmetry remain key constraints to large-scale adoption. The study concludes that achieving a circular-bioeconomy through palm oil biomass valorisation requires coordinated progress across technological innovation, institutional alignment, and market transformation. Future research should advance…

A Review of Decarbonization Strategies in Oil Palm PlantationsToward Net-Zero Emissions
type: item
description: Decarbonizing oil palm plantations has become increasingly critical as global climate commitments intensify and agricultural supply chains face growing pressure to align with net-zero emission targets. Recent scientific literature highlights a wide range of technological, ecological, and governance-based mitigation approaches, yet these findings remain fragmented across disciplines, limiting the sector’s ability to identify strategies with the highest carbon-reduction potential. This study addresses this gap by conducting a systematic literature review aimed at (1) identifying and classifying the dominant decarbonization strategies implemented in oil palm plantations, and (2) evaluating their relative significance, mitigation potential, and practical feasibility across diverse production contexts. This research adopts a qualitative Systematic Literature Review (SLR) design following the PRISMA protocol. Data were gathered exclusively from peer-reviewed journal articles indexed in Scopus, using structured keyword refinement and multi-stage inclusion criteria to ensure thematic relevance. A total of 39 publications met all eligibility requirements and were analyzed through thematic synthesis. Data analysis involved qualitative coding, cross-study comparison, and extraction of quantitative indicators related to emissions, mitigation performance, and implementation considerations. The findings reveal five dominant decarbonization pathways: methane mitigation from palm oil mill effluent, energy-efficiency improvements, biomass-based fuel substitution, landscape-level carbon sequestration, and digital MRV enhancement supported by governance instruments. Methane mitigation demonstrates the highest reduction potential, followed by energy transformation and peatland restoration. The review concludes that integrated, multi-dimensional approaches are necessary to achieve netzero trajectories. Future studies should explore hybrid decarbonization models, long-term MRV performanc…

Variability in the Duration of Rains and Other Elements of the RainCourse
type: item
description: Rains of varying intensity and duration have different effects on the water balance of territories and economic indicators of regional development. The paper examines the features of changes in time and in various physical and geographical conditions of the duration of rains and the position of the maximum intensity during rain. It is shown that in mountainous areas there is more precipitation, both in quantity and frequency.The research used methods of mathematical statistics and graphical analysis.In general, for all four meteorological stations, which were studied, a similar distribution of the probability of occurrence of rains with a given duration is characteristic. Rains lasting more than 400-500 minutes occur in less than 10% of all meteorological stations. For rains lasting less than 300 minutes, there is a difference in the probability of occurrence of 5-10% between meteorological stations. Some limits of air humidity, air temperature and soil surface at which rain was not observed are determined, what is important when forecasting. Analysis of the influence of meteorological parameters on the duration of rains and the position of the maximum intensity during rain shows that at an average relative humidity of less than 45-50 percent there was practically no rain, and at a minimum relative humidity of less 30% as well. Air temperature (average, maximum and minimum) of 20-25 °C is critical, above which rains lasting more than 400-500 minutes did not occur. The longest rains are observed at low average daily air temperatures, less than 10 °C. At a minimum soil temperature of 20 °C and above, rains are practically not observed (4 cases out of 989). At an absolute maximum soil surface temperature of more than 50 °C, prolonged rains of more than 500 minutes are also practically not observed.

Research on Control Technologies for Hydrogen Sulfide BearingShale Oil Wells in China’s Shengli Oilfield
type: item
description: Pyrite is abundant in some shale oil blocks of the Shengli Oilfield, China. During the development process, the high-temperature and high-pressure formation environment induces a thermochemical reaction between pyrite and hydrocarbons, generating and releasing hydrogen sulfide (H₂S). This poses a serious threat to safe production, environmental protection, and crude oil quality. This paper provides an in-depth analysis of the formation mechanism of hydrogen sulfide in shale formations, identifying the high-temperature pyrolysis of pyrite in a closed system as the primary sulfur source. To address this issue, a high-temperature desulfurizer suitable for shale oil wells has been developed. This desulfurizer exhibits excellent characteristics, including hightemperature resistance (adaptable to formation temperatures), rapid reaction, high desulfurization efficiency, large sulfur capacity, and partial regenerability. By injecting the desulfurizer into the formation alongside fracturing fluid during the fracturing process, source control and treatment of hydrogen sulfide are achieved. Successful field applications in five wells demonstrate that this technology significantly reduces hydrogen sulfide concentrations during well opening and production, yielding effective treatment results. It provides an efficient technical approach for the safe and high-efficiency development of similar hydrogen sulfide-bearing shale oil reservoirs.

Impact Assessment of Cloud Seeding in Karnataka, India
type: item
description: The State of Karnataka in Southern India falls in the rain shadow region and is highly prone to drought conditions. Most of the monsoon rainfall occurs in the months of June and August with few rainy days during September to December. The State experienced severe rainfall deficiency in the years of 2017 and 2019 with limited rainfall in most parts of the State. The cloud seeding exercise was taken up by the State Government in both years to mitigate the adverse impact. Two cloud seeding aircrafts (Beach Aircraft King Air 200) of Weather Modification INC, USA with meteorological instruments and cloud seeding equipment were operated. Daily advisory on convective cloud development and potential seeding locations was generated using real time data from 3 Doppler Weather radars, Radio Sonde ascents, INSAT satellite data and high-resolution model runs by India Meteorological Department and Space Applications Centre (ISRO). Real time aircraft observations of cloud temperature, liquid water content and updraft winds helped to target potential clouds for hygroscopic and glaciogenic seeding. The data from the dense rainguage network of over 6000 automatic and telemetric rainguages operated by the Karnataka State Natural Disaster Monitoring Centre was utilized to study the impact of cloud seeding operations. Evaluation of the seeding has been carried out using spatial and statistical methods. The quantitative results indicate positive impact of cloud seeding leading to 10-15 % increase in rainfall with improved geographical spread. Thus cloud seeding carried out in a controlled and systematic basis can thus emerge as a viable support to mitigate recurrent drought hit areas. This paper presents the results of the evaluation study.

Global Green Betrayal: Excuses Are Plenty, Forests Empty, and TruthOverlooked
type: item
description: Global outrage over COP30’s Amazon tree-felling mirrors a far broader crisis, as deforestation accelerates across continents and ecosystems collapse under human pressure. Biodiversity is plummeting at record speed, with wildlife abundance down nearly three-quarters and economic losses reaching trillions annually. Agricultural expansion, industrial extraction, climate-driven wildfires, and conflict now drive unprecedented forest destruction, especially in tropical regions. Together, these forces push the planet toward an ecological breaking point, raising an urgent action demanded to safeguard the world’s remaining forests before they are lost forever.

Genetic Studies on Mealiness, Dry Matter, Root Number and FreshRoot Yield, in Cassava (Manihot esculenta Crantz)
type: item
description: Breeding for increased mealiness, number of roots, dry matter content and good fresh root yield enhancing the production of cassava to meet consumer acceptance for cassava storage root and its products has become the next challenge in cassava breeding in Sierra Leone. These traits are essential for cassava production as they are the most preferred traits for end-use consumption. Data were subjected to statistical analyses using SAS version 9.3. Analytical tools employed included general analysis of variance and diallel analysis of variance for combining abilities and estimates. The mean performance for number of roots per plant ranged from 4.85 to 2.50 for crosses IBA 120004 x I088693 and IBA120004 x TMEB1 with a grand mean of 3.59, while the mean performance for fresh root yield ranged from a highest of 0.80kg/plant, I9100416 x I088693 to 0.23kg/plant UBJ120003 x IBA 120004. Significant differences were observed among the 65 F1 crosses for dry matter (P < 0.01); number of storage roots per family and fresh root yield per family at P < 0.05. General combining ability (GCA) variance was significant only for fresh root yield per family at P < 0.05 whereas specific combining ability (SCA) variance were significant for dry matter (P < 0.05) and number of storage roots at P < 0.01 and fresh root yield at P < 0.05. High variability for different traits had also been reported in cassava. The mean FRSY and SRN at the seedling evaluation stage in this study were lower than those reported by Ojulong et al., Mtunda and Tumuhimbise et al., Highest magnitude of positive and significant SCA effects was shown by F1 progenies from crosses UBJ120003 x UCC2001(246), UBJ120003 x TMEB693, UBJ120003 x TMEB 419, UBJ120003 x MM961871, UBJ120003 x I088693, TMEB419 x I088747, TMEB419 x I011368, MM961871 x I9100416, IBA120004 x I088747, IBA 120004 x I088693, IBA961165 x I088693, IBA 961165 x I088693, and I9100416 x I088693.

Enhancing Geospatial Data Integration and Completeness throughSemantic Web and Linked Open Data
type: item
description: This paper investigates methods for improving the integration and completeness of heterogeneous geospatial datasets using Semantic Web technologies and Linked Open Data. Interoperability issues, fragmented data sources, and incomplete datasets remain persistent challenges in the geospatial domain—often exacerbated by proprietary formats and lack of coordination among stakeholders. To address these, we propose an ontology-based approach built on the principles of knowledge representation and reasoning. By leveraging the Universal Spatial Knowledge Base (USKB) and rulebased inference mechanisms, our method facilitates semantic interoperability and supports completeness analysis across diverse data sources. As a demonstration of this approach, we present SPALOD (Spatial Data Management with Semantic Web Technology and Linked Open Data), a platform designed to integrate and manage complex geospatial datasets. SPALOD illustrates how semantic reasoning can ensure consistent data quality, enhance interoperability, and enable seamless integration across systems. Our results underline the feasibility and impact of semantic-enriched data management strategies in the geospatial context, offering a scalable solution for harmonizing and enriching spatial information about bicycle network.

Environmental Clearance Process: The Role of Social ImpactAssessment (SIA) in Development Projects
type: item
description: The Environmental Impact Assessment (EIA) process is a multidisciplinary tool designed to ensure that environmental and social considerations are integrated into decision-making for development projects. While traditionally focused on biophysical impacts, the inclusion of Social Impact Assessment (SIA) has become increasingly vital. SIA examines the consequences of interventions on human populations, including changes in livelihoods, community cohesion, cultural practices, and social well-being. This paper explores the significance of SIA as an integral component of EIA, with reference to the Indian regulatory framework while situating the discussion within a global context. It highlights key principles, methods, and processes of SIA and emphasizes its role in fostering equitable and sustainable development. The paper concludes that integrating SIA into EIA not only strengthens environmental governance but also ensures inclusive growth and resilience for future generations.

Managing Overall Performance within Metropolises or How toRespond to Society’s Values
type: item
description: In the face of increasing awareness of societal and environmental issues, local authorities, who are closest to the citizens, must set an example and instills values in all the actors of the territory. In terms of SAR, it is the companies that have been the most studied in recent years. Local and regional authorities must be accountable and, in order to do so, must have better governance and management. Metropolises were created since 2012 to decentralize state powers. A new organization and governance have been set up within the territories. In fact, metropolises are more or less important intercommunal ties and they must operate considering the expectations of each city.

Assessment of Sanitation Facilities, Hygiene Practices and Challengesin Urban and Rural Public Primary Schools in Oshimili South LocalGovernment Area, Delta State
type: item
description: This study assessed sanitation facilities, hygiene practices and challenges in urban and rural public primary schools in Oshimili South local government area, Delta State. Three research questions guided the study and were correspondingly hypothesized. The design of the study was cross-sectional survey research design. A multistage sampling technique was employed to select, 234 pupils and 145 staff from the 2024/2025 academic year, resulting in a total sample of 379 participants drawn from a population of 6,204 across urban and rural schools. The instruments for data collection were 31-item structured questionnaires on 4-point modified Likert scale designed for staff and pupils by the researcher. Cronbach’s Alpha method was used to ascertain the internal consistency of items and correlation indices of 0.83 and 0.80 were obtained for staff and pupils’ questionnaires respectively. Data collected were analysed using frequency count and percentage statistics while independent sample t-test statistic was used to test the formulated hypotheses at α = 0.05. Results showed among others, that the current conditions of sanitation facilities in urban public primary schools (57.2%) are more favourable compared to rural (43.9%) schools with inadequate facilities; a statistically significant difference in the quality of sanitation facilities between rural and urban public primary schools, with urban schools being favoured (t = 2.325, p <0.021). The study recommended among others that, Delta State and Oshimili Local Governments, and school management should prioritize the provision and upgrading of sanitation facilities (toilets, water supply, waste management systems) particularly in rural public primary schools.

type: item
description: This study presents an electrochemical reduction cell model for photosynthesis aimed at enhancing carbon dioxide capture. Utilizing Simulink, we simulated a system where varying current supplies were applied to assess the production of formic acid and the consumption of carbon dioxide over time. The model demonstrated a direct correlation between current supply and the rates of formic acid generation and CO2 consumption, with significant increases observed at higher current levels. Initial measurements indicated a formic acid production rate of approximately 0.000492 moles/s at 0.1 A, which increased substantially to 0.002217 moles/s at 0.450 A. Concurrently, CO2 consumption escalated from zero to over 36.42 moles/s, underscoring the efficacy of the electrochemical process. The results highlight the potential of electrochemical reduction cells in mitigating atmospheric CO2 levels while producing valuable chemicals, thereby contributing to advancements in sustainable energy and environmental management. Further investigations will focus on optimizing operational parameters to maximize efficiency and scalability for practical applications.

Solving the Conundrum of Battery Electric Cars Versus HydrogenElectric Vehicles
type: item
description: The hydrogen powered vehicle was invented long before the battery electric car but both were beaten by the petrol/diesel combustion engine that is now being chopped as the zero-emission transition of many nations is aiming for net zero in 2050. The conundrum is that present designs of vehicles might be pure battery or could instead be hydrogen-fuel-cell-battery drive train, allowing much more onboard energy storage. The success of the lithium battery that started near 2008 has been extended in many countries, giving exponential rise in pure battery designs, but there are several snags that still need to be solved. In contrast, the hydrogen-fuel-cell-battery-electric-vehicle only became economically viable near 2018, giving a decade lag, but with numerous advantages such as low price, less weight, long range and rapid refuelling. The purpose of this paper is to outline key difficulties, mainly of infrastructure, before attempting to predict the future advances of both technologies.

Pressure Induced Electronic Transitions in Rare Earth Compounds:A Pathway to Novel Superconducting Phases
type: item
description: High-pressure conditions are known to significantly alter the electronic structures and superconducting behaviors of rare-earth compounds. This study focuses on pressure-induced electronic and structural transitions in selected neodymium-based compounds (NdP, NdAs, NdSb, NdBi) using a combination of high-pressure experimental techniques and first-principles calculations. Key phenomena investigated include lattice distortions, f-electron hybridization, density of states (DOS) modifications, and valence state fluctuations under compression. Our results reveal that increasing pressure induces structural phase transitions in these Nd monopnictides, resulting in changes in band dispersion and electron localization. Pressure-driven enhancement of f-electron hybridization and narrowing of conduction bands suggest favorable conditions for superconducting pairing mechanisms. We also observe significant modifications in the DOS near the Fermi level, a potential indicator of superconducting phase emergence under extreme pressure. Although superconductivity has not yet been observed in these materials experimentally, our computational modeling predicts possible superconducting states in compressed NdSb and NdBi. This study provides new insights into the pressure-dependent electronic behavior of Nd-based rare-earth monopnictides and identifies promising candidates for further high-pressure superconductivity exploration. Future work should involve low-temperature, high-pressure transport measurements and exploration of doped or hydrogenated variants to assess their superconducting potential.

Electronic Structure Modifications of Lanthanum Pnictides underHigh Pressure and Implications for Superconductivity
type: item
description: Lanthanum pnictides (LaY, where Y = N, P, As, Sb, Bi) are a compelling class of materials whose electronic and topological properties are highly tunable under high pressure. Using first-principles density functional theory (DFT), this study explores the evolution of electronic structure, density of states (DOS), orbital hybridization, Fermi surface topology, and topological characteristics of LaY compounds under pressures up to 50 GPa. Results reveal that increasing pressure induces band broadening and metallization across the series, with lighter pnictides transitioning from semiconducting to metallic behavior and heavier counterparts exhibiting enhanced semimetallicity. Notably, LaSb and LaBi display pressure-driven spin–orbit coupling (SOC)-induced band inversions, confirming their nontrivial topological character through parity eigenvalue analysis at timereversal invariant momentum (TRIM) points. Calculated DOS at the Fermi level shows a pressure-dependent increase, correlating with a rise in estimated superconducting transition temperatures (Ts). Fermi surface complexity also increases under pressure, supporting favorable conditions for superconductivity. These findings highlight the critical role of pressure in manipulating the quantum states of LaY compounds and suggest promising pathways for engineering topological superconductors for next-generation electronic and quantum devices.

Mathematical Model and Neural Networks for the DynamicHysteresis Losses Calculation
type: item
description: In this paper, the dynamic hysteresis energy losses of the FeBSiC amorphous alloy sample were determined by means of mathematical model and neural networks. The changes in magnetic hysteresis curves as a function of frequency are introduced via the variation of the coercive magnetic field. So, a neural network (NN) has been trained to learn this function and used in the modelling of frequency-dependent hysteresis with a mathematical model. The model can calculate core losses based on the input parameters obtained from experimental measurements. This study is especially aimed at giving improved issue to avoid the empirical functions that require the identification of several parameters.

Effective Utilizations of Red Mud with Emphasis on CircularEconomy
type: item
description: Red mud (Bauxite residue) is an industrial by-product (IBP) generated as a vast volume, mainly from aluminum industries. Disposal of red mud (RM) in open land leads to serious environmental hazards, occupies a vast land area, and incurs enormous economic and social costs. Storage and maintenance of red mud dumps are also costly, and their failures frequently flood vast areas, killing people and cattle and disrupting the ecosystem. Conversely, research data shows that the red mud has enormous potential to transform its valuable resources. Due to the growing demand for bauxite ore for aluminum industries, the volume of red mud has been increasing rapidly, causing an inevitable multidirectional consequence in the context of environmental and sustainability issues. On the other hand, the rising demand and resource crises continue to deplete natural resources; the gap of enormous resource availability has become a severe challenge for scientists, researchers, and institutional R&D to develop a process technology to re-generate resources through the recycling of wastes. Using red mud through the circular economy concept can replenish the depletion of virgin resources (mainly the construction sector) and extract valuable materials and metals from red mud. Recycling RM through the circular business model can increase the sustainability of natural resources, reduce environmental pollution, water contamination, and land pollution, increase land area, replenish the depletion of natural resources, enhance economic growth, and mitigate global warming and climate change.

Divesting Nigeria’s Niger Delta Oil Blocks: Challenges, Solutions,and Strategic Implications
type: item
description: For decades, the people of the Niger Delta have lived in extreme poverty as a result of the loss of their livelihoods caused by pollution from petroleum exploration activities, while International Oil Companies (IOCs) have built super-rich empires on the revenues of crude oil extracted from the region, leaving behind a devastated environment, social crises, and death. IOCs are now divesting for a number of reasons, including instability, oil theft, and ongoing resentment from host communities, all of which contribute to the high costs and risks involved with sustained operations. Given the region’s current high level of environmental awareness, it is more likely that people will hold IOCs responsible for oil spill cleanup, remediation, and compensation. This paper reveals the issues associated with the IOCs’ ongoing divestment of significant oil blocks in the Niger Delta, as well as available solutions that can bring about peace and stability in the region. It is recommended that the only way out of the current environmental calamity in the Niger Delta is by environmental restoration and that before divesting the assets they own, IOCs should demonstrate goodwill by dealing with their environmental legacies in the region. The government, for its part, should address Niger Delta stakeholders’ concerns regarding a provision or clause in the PIA that bans host communities from collecting their 3% benefit from oil corporations in the case of crude oil theft in their jurisdiction, since this will assist to rebuild public trust. In addition, before approving the current divestment process, the government should force IOCs to address damages to the environment in the Niger Delta.

Design of Controllers for DC-DC Buck Converters
type: item
description: The design of controllers for DC-DC buck converters using PID controller and fuzzy logic controller has been the subject of numerous research studies in recent years. The objective of these studies is to improve the performance of the buck converter in terms of output voltage regulation, transient response, and efficiency. PID controller is a commonly used feedback control mechanism that uses proportional, integral and derivative terms to adjust the output of the system. The PID controller is widely used in DC-DC buck converters due to its simplicity and effectiveness. The proportional term of the PID controller adjusts the output based on the difference between the actual and desired output, the integra term is used to eliminate steady-state error, and the derivative term improves the transient response of the system. On the other hand, the Fuzzy Logic Controller (FLC) is a more complex control mechanism that uses linguistic rules and fuzzy sets to adjust the output of the system. FLCs have been shown to be effective in DC-DC buck converters due to their ability to handle non-linearities and uncertainties in the system. In this paper, we are simulating PID control and fuzzy logic control for both single stage and cascaded converter. The hardware implementation of the former is done as well, and the results are compared based on rise time, settling time, peak overshoot and offset at steady state.
