The results indicated that 1:3 was the best ratio and had efficiencies of removal 98.28 % for phosphate, 98.92 % for nitrate, 98.27 % for total dissolved solids, 96.11 % for biochemical oxygen demand, and 95.29 % for chemical oxygen demand. Maximum efficiencies were found at pH 3, 0.4 g/L dosage, 15 minutes contact time, and 40 minutes settling time. The results show that the watermelon seed coagulant blended with commercial alum at a ratio of 1:3 is the ideal blend for wastewater treatment of the highly contaminated Gibe River.

The study began with a quantitative phytochemical analysis of SLM, followed by Gas Chromatography-Mass Spectrometry (GC–MS) of methanolic leaf extracts. 180 juveniles, averaging 151.12 ± 8.54 g, were randomly assigned to four groups, each with 45 fish and three replicates in a Completely Randomized Design. The groups–Control, T1, T2, and T3 were fed diets containing 0 %, 2.5 %, 5 %, and 7.5 % SLM, respectively. Phytochemical analysis revealed substantial amounts of phenols, flavonoids, alkaloids, and saponins. GC–MS identified 13 distinct compounds, including fatty acids, fatty acid esters, ethers and aldehydes. Fish were weighed at the study's conclusion, and blood samples were collected for hematological and serum lipid profile analysis. Condition factors and survivability were similar across all groups (<em>p ≥ 0.05</em>). However, final body weight (FW), weight gain, specific growth rate, total feed intake (TFI), and feed conversion ratio varied significantly (<em>p &lt; 0.05</em>). The control group exhibited the highest FW (339.20 ± 3.16 g) and TFI (597.05 ± 6.65 g), with results comparable to T1. Conversely, TFI and growth progressively declined with increasing SLM levels, with T3 showing the lowest FW (299.62 ± 7.83 g) and TFI (541.06 ± 20.39 g). Hematological and serum profile indices were similar across groups (<em>p ≥ 0.05</em>). These findings highlight the nutritional and ethnopharmacological relevance of <em>A. muricata</em> leaves.

In this study, rice husks (RH) from locally grown rice cultivars were obtained from two rice mills in Nigeria and pyrolysed to biochar at 400 and 500 °C before chemical modification using 2 M KOH. The adsorption capacities (Q_e) of the pristine RH biochar pyrolysed at 400 °C for Zn²⁺ and Pb²⁺, following synthetic wastewater treatment, were 462.5 and 142.8 mg/g, and at 500 °C, 1047.5 and 275.5 mg/g, respectively. KOH-modified biochar outperformed its pristine counterparts, as the recorded Q_e for Zn²⁺ on the KOH-modified RH1 pyrolysed at 400 °C (KRH1_400B) showed 1547.75 mg/g, and 1534.25 mg/g at 500 °C (KRH1_500B), respectively, with a 98 % Zn²⁺ removal efficiency. For Pb²⁺, all KOH-modified biochars for RH1 and RH2 showed a 100 % removal efficiency and maximum Q_e of 275.5 mg/g. Scanning Electron Microscopy (SEM) revealed increased poration of 200 µm sized pores, densely distributed across the rough surface of the KOH-modified biochar. Energy Dispersive Spectroscopy showed varying carbon and silicon compositions of the RH1 and KRH1_400B. Fourier Transform Infrared Spectroscopy corroborated structural disparities in SEM, as compositional differences in the observed functional groups were identified in the chemically modified biochar.

The main objective of this work is to investigate the feasibility of powering gym loads using the DC bus through grid-tied inverters, while ensuring efficient energy management and user-specific operation. The novelty of our approach lies in the implementation of a fuzzy logic control (FLC) strategy to achieve multiple control objectives within the gym microgrid environment, alongside a refined energy management algorithm that facilitates the flow of energy between intermittent generation sources and the variable demand from users. The system comprises several subsystems: (i) stationary bikes connected to the DC bus via AC/DC converters acting as intermittent power sources; (ii) a PV generation system interfaced through a DC-DC boost converter; (iii) gym loads. The main control objectives are as follows: (a) each stationary bike control the speed applied by the athlete to extract energy; (b) the system ensures the protection of the energy storage system by monitoring its current and voltage; (c) Extract the maximum power available from the PV system; (c) all objectives are achieved while maintaining the DC bus voltage at a specified reference value. To achieve these objectives, a fuzzy logic control approach is employed, providing adaptability and robustness in managing the dynamic behavior of the system. The system’s performance is demonstrated using the MATLAB/Simulink environment, with numerous simulations confirming that all control objectives are met.</div></div>","PeriodicalId":21690,"journal":{"name":"Scientific African","volume":"28 ","pages":"Article e02674"},"PeriodicalIF":2.7,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143814933","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}

Three types of distinct vibrating configurations namely, Pinned-Pinned, Clamped-Pinned and Clamped-Clamped end conditions are considered. The objectives are three-fold, viz: to (i) compute accurately the natural frequencies of the Rayleigh pipes under consideration (ii) the second determine and analyze the influence of rotatory inertia parameter, foundation stiffness parameters, non-uniform terms, material gradient index parameter, mass ratio and the fluid flow velocity on the natural frequencies of the vibrating pipe, thereby coming up with some conclusions concerning the dynamic behaviour of the pipe under consideration, and (iii) the third objective is to develop the variational iteration method (VIM) scheme for examining vibration characteristics of non-uniform AFG fluid-transporting Rayleigh pipe lying on variable Pasternak foundation.

Key results show that: (1) the choice of global soil dataset minimally affects streamflow simulations, especially for monthly time steps and large-scale catchments, though different datasets often require distinct parametrizations to achieve similar performance; (2) for sediment and nutrient transport simulations, soil data selection becomes crucial for model accuracy; and (3) the relationship between soil data resolution and model performance is not linear, with high-resolution data not always guaranteeing better results.

By combining socio-economic surveys, remote sensing analysis, the benefit transfer method, and the Cellular Automata (CA) model for future projections, we quantified LU/LC dynamics and their implications for ES. Results indicate a significant expansion of built-up areas (+122.46 %) and mangrove forests (+15.66 %) from 2000 to 2022, accompanied by declines in swamp forests (-14.17 %), forest plantations (-57.14%), shrublands (-17.18 %), and farmland/fallows (-26.02 %). The CA model predicts continued urban expansion, with settlements increasing by 33.61 % from 2022 to 2052 at the expense of natural ecosystems.

This study delved into the yield dichotomy between conventional rainfed and flood-recession rice production systems in the Oti Region of Ghana. The study used cross-sectional data and an endogenous treatment effect model for the comparative analysis. The results revealed that the two categories of farmers have different factors influencing their decision to use any of the two systems. While education, agriculture extension contacts, and contract farming increase farmers' probability of using flood-recession rice production system; farmers who are more experience and those who stay far away from river banks tend to engage in convention rice farming. For rice yield, capital, labour, pesticide use, credit, extension contacts, education, contract farming, and location are critical factors. Farmers cultivating rice under a flood-recession system can obtain 0.85Mt/Ha yield higher than their counterparts who produce rice under rainfed. In a nutshell, there is compelling evidence that the flood-recession rice production system has the potential to minimize the effects of rain failure on crops. Therefore, farmers should be sensitized to use river banks for flood-recession rice production whilst considering production cost implications.
