The specific surface areas of the plant native and plant treated were 8.86 and 19.45 m² g^-1, respectively, indicating a significant specific surface area of the plant treated. A number of functional groups were determined, particularly C-O, NH₂, C-H, and</div><div>-OH, which promote the binding of the phosphate ions to the adsorbent. The SEM also shows that the adsorbent has a homogeneous texture with deep voids and significant porosity. After treatment with an alkaline solvent, soluble organic matter was reduced by 75.14 %, 86.16 %, and 82.22 % for biological oxygen demand, chemical oxygen demand, and organic matter, respectively. We could perfectly fit the kinetic data using the pseudo-second order model, while the Langmuir model proved an excellent fit for the equilibrium data. The modified plant maximum amount of phosphate ion adsorption is 909.09 mg g^-1 under the optimal conditions: biomass ratio of 3.75 g L^-1, contact time of 10 min, pH = 9.2 at 35°C. Thermodynamic values show that adsorption is realizable, spontaneous, and endothermic. The prepared biomaterial (costing 0.765 $ per 20 grams) was easily regenerated using an aqueous NaOH solution, with a slight reduction in its adsorption capacity (55.65 %) up to five cycles. The results of Taguchi experimental design and response surface methodology showed that initial concentration, temperature, and ratio are the most significant factors influencing elimination efficiency, with contributions of 98.39 %, 0.62 %, and 0.03 %, respectively. Biomaterial performance has been proven in the lentil seed germination test, as well as its effectiveness in removing phosphate ions from wastewater.</div></div>","PeriodicalId":21690,"journal":{"name":"Scientific African","volume":"28 ","pages":"Article e02748"},"PeriodicalIF":2.7,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144105770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Against this growing threat, advanced holistic anti-drone systems are highly required to reinforce airspace safety and security. Prior to neutralizing a target activity, the anti-drone is required to detect and identify the airborne target. Indeed, countering a foe target’s activity properly, namely a drone requires an efficient anti-drone system with a variety of agents, technologies, and approaches. Although existing scientific contributions have made significant progress in the detection and tracking of drones, they appear incomplete when it comes to proposing a holistic anti-drone architecture with sophisticated and novel countermeasures designed to meet the current needs. As part of the proposed architecture, we seek to address this gap by developing a holistic architecture including the main aspects, units, and phases of an anti-drone. The proposed anti-drone architecture is a Multi-Agent System (MAS) combining AI-driven Transformer-DeepSORT tracking, Blockchain-secured communications, and AI techniques to meet the existing needs. Also, we propose a collaborative electromagnetic neutralization to intercept the target and retrieve the drone’s frame without causing potential harm and damage. In addition to providing a holistic approach to anti-drone operations, the proposed architecture considers regulatory and ethical considerations in drone mitigation, such as drone detection, tracking, threat assessment, and neutralization. Our findings demonstrate that this approach not only enhances tracking accuracy and response time but also ensures higher system resilience against evolving drone threats.</div></div>","PeriodicalId":21690,"journal":{"name":"Scientific African","volume":"28 ","pages":"Article e02753"},"PeriodicalIF":2.7,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study aimed to assess the effects of farmers’ timely access to tractor services on their efficiency. This study examined smallholder arable crop farmers’ technical, allocative, and economic efficiencies. The household survey gathered data on farmer characteristics, socio-economic, and production. Data was collected from 470 smallholder arable crop farmers in Central District, Botswana. The Stochastic Frontier Approach (SFA) was used to analyze the efficiencies, and the Tobit regressions were used to determine the factors influencing the efficiencies. The results show that poor quality and delays in farmers’ access to tractor-hire services negatively affect technical and economic efficiencies. Smallholders had a mean technical efficiency score of 44 %, an allocative efficiency score of 6.6 %, and an economic efficiency score of 2.9 %.

The passive \"crowbar and dc-chopper\" technique has been employed to protect DFIGs. However, it may not be sufficient for some of the transient profiles. For this reason, the Low Voltage Ride Through (LVRT) has been employed by implementing Control of Flux Neutralization Current (CFNC) for transient response assessment. Moreover, the induced electromotive forces (IEFs) in both circuits (stator and rotor) were modeled on the DFIG, and the comparative performance of the DFIG models with and without CFNC was examined. The system behavior was examined for symmetrical three-phase faults, considering the cases with and without the stator/rotor coupling dynamics. This study uses numerical modeling and time-domain simulations with MATLAB/Simulink to analyze the transient behavior of the DFIG system under fault conditions. No experimental tests have been carried out, and future work will aim at a real-time implementation to assess practical feasibility. DFIG quantities were analyzed and compared, including 0.69 kV output voltage, mechanical speed response, electromagnetic torque variations, rotor and stator direct quadrature (d-q) axis currents, 22 kV bus terminal voltage, and, a DC-Link voltage. The results reveal that CFNC reduces the duration of oscillations by more than 50%, stabilizing currents in 1.18 s instead of 3.5 s and the DC-Link voltage in 1.1 s instead of 3.5 s, significantly improving LVRT capability and transient stability.</div></div>","PeriodicalId":21690,"journal":{"name":"Scientific African","volume":"28 ","pages":"Article e02745"},"PeriodicalIF":2.7,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143942182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
