Authors: Ezeanya-Bakpa C.C. , Adams A.A. 
Published: August 2024

Drug-resistant pathogens are responsible for high mortality and morbidity rates. Plant remedies are known to treat microbial infections. This research was aimed to determine the susceptibility of drug-resistant fungi (Candida albicans) and bacteria (Staphylococcus aureus and Escherichia coli) responsible for candidiasis and urinary tract infection to Psidium guajava L. leaf extracts. The P. guajava leaves were subjected to extraction using two solvents (methanol and ethanol) with varied polarity and concentrated with a rotary evaporator. Qualitative phytochemical screening of the extracts was done. Antimicrobial susceptibility testing was done to identify the resistant pathogens. The antimicrobial effect of the extracts was established using the agar-well diffusion method at a given concentration. The methanol and ethanol extracts had both phenols but tannins were absent rather. Flavonoids were detected in the ethanol extract. Multi- drug resistance was observed among the pathogens particularly, E.coli. The antibiotics with 100% resistance by the bacterial pathogens were Amoxicillin and Erythromycin whereas C. albicans showed resistance to Ketoconazole. The extracts of P. guajava L. leaves had an inhibitory effects against drug-resistant E. coli and C. albicans, whereas S. aureus was resistant to the extracts. The methanol extract had a higher antibacterial activity with mean±SD zone of inhibition 28.0±1.56 mm and 35.5±2.25 mm against E.coli and C. albicans respectively. In an in-vitro study with such high susceptibility to methanol extract; it is paramount to consider P. guajava L. leaf as a good candidate with natural therapeutics against drug-resistant urinary tract infection and candidiasis, an outcome that could necessities further pharmacological elucidation.

Opportunities for Blue food in a turbulent future - what’s ahead for a growing aquaculture industry?
Authors: Troell Max 
Published: August 2024

The scale and speed of human activities and technological developments have substantially increased since the 1950s resulting in reshaping of the biosphere and moving humanity into a new geological epoch — the ”Anthropocene”. This is characterized by changes in several Earth system processes and structures on which human life depends. The global food system is a major driver of changes in the biosphere – for example greenhouse gas emission and other environmental changes including global biodiversity loss. Blue foods (aquatic foods) have slowly made their way into international high-level sustainability discussions and increasingly now form part of nutritious, climate smart and low environmental impact food narratives. Today farmed and captured aquatic animals and plants play a central role in food and nutrition security for billions of people, and constitute cornerstones for many livelihoods, economies, and cultures. The blue food portfolio is highly diverse and also supported by a wide range of ecosystems, cultural practices and production modalities. This diversity poses both potential for supporting food system resilience in uncertain times, and challenges for making simple guidance on sustainable development of food production. The anticipated continuous growth of aquaculture trigger questions related to “what, how and why”. Many blue foods are rich in bioavailable micronutrients and can be produced in ways that are more environmentally sustainable than some terrestrial animal-source foods. However, blue foods are diverse and planning for future expansion through i.e. aquaculture involves identification of properties for different species and systems, as well as identification of development priorities and acknowledging trade-offs and context specificity out from a broader Sustainable Development Goal framework. Environmental stressors may narrow the window for blue food production and climate change is a main driver affecting the function and productivity of aquatic and supportive terrestrial ecosystems.

Data-driven decision-making model for renewable energy
Authors: Wisdom Udo  , Adekunle Stephen Toromade  , Njideka Rita Chiekezie  
Published: August 2024

The transition to renewable energy sources is critical for achieving sustainable development and combating climate change. As the renewable energy sector rapidly evolves, there is a growing need for advanced decision-making frameworks that can effectively navigate the complexities of energy production, distribution, and consumption. This paper explores the development and application of a data-driven decision-making model tailored to the renewable energy industry. The model integrates real-time data analytics, machine learning algorithms, and predictive modeling to enhance decision-making processes in areas such as resource allocation, grid management, and investment planning. By leveraging vast datasets, including weather patterns, energy consumption trends, and market dynamics, the model provides actionable insights that enable stakeholders to optimize energy production, forecast demand, and mitigate risks associated with renewable energy projects. The model's predictive capabilities are particularly valuable in managing the intermittency of renewable energy sources, such as solar and wind, by improving accuracy in forecasting energy output and aligning it with demand. Additionally, the model supports strategic investment decisions by identifying high-potential areas for renewable energy development based on data-driven assessments of resource availability, infrastructure readiness, and economic viability. The paper also addresses the challenges of implementing data-driven models in the renewable energy sector, such as data quality and integration issues, the need for specialized technical expertise, and the importance of aligning the model with regulatory and policy frameworks. Case studies are presented to illustrate the practical application of the model in different renewable energy projects, highlighting the benefits of data-driven decision-making in enhancing operational efficiency, reducing costs, and supporting the sustainable growth of the energy sector. The findings underscore the potential of data-driven approaches to revolutionize renewable energy management, making them indispensable tools for achieving a clean energy future.

Right to Breathe: A Constitutional Path to an Environmental Amendment
Authors: Bobeck Kyle J. 
Published: August 2024

The constitutions of more than three-quarters of the countries on Earth explicitly reference environmental rights or responsibilities, but that is not the case in the United States. The U.S. Constitution contains no unequivocal right to a clean environment, and attempts to sway federal judges to find an implied right have not been successful. Recently, in Juliana v. United States, plaintiffs pursued an order requiring the federal government to reduce the country’s carbon dioxide emissions. While the Oregon district court ostensibly favored such an order, a divided Ninth Circuit held in 2020 that the plaintiffs lacked standing.
Efficiency of Robust Observer Design in Power-Assisted Wheelchair Applications
Authors: Kien Vu Ngoc  
Published: August 2024

Unlike manual wheelchairs, power-assisted wheelchairs feature a unique design that allows users to combine their own propulsion with the assistive system. Recently, various studies have concentrated on the control systems for power-assisted wheelchairs. This paper introduces a 2 step control design utilizing a quasi Linear Parameter Varying (LPV) to tackle this complex control problem. The first step involves designing an observer for state and unknown input estimation. The next step proposes a controller to manage parameter including positive gains and input of the system. The control procedure is expressed as convex optimization problems with linear matrix inequality (LMI) constraints, efficiently solvable using standard numerical solvers. To validate the effectiveness of the solution, both simulations and real-time applications are performed. Both simulations and real-time experiment demonstrates that the proposed assistive control algorithm offers excellent maneuverability.
