A total number of 40 vertical electrical sounding VES points were used for the investigation using Schlumberger array and data obtained were analyzed using curve matching and computer iteration techniques. The data revealed a 3-layer (A, KA and H Curve type) and 4-layer (A and H-curve type). In the 3-layer system, the apparent resistivity of the first layer ranged from 18.90 Ωm to 183.20 Ωm with a corresponding thickness of 0.7 m to 14.8 m. The second layer has apparent resistivity value ranged from 13.50 Ωm to 423.80 Ωm with a corresponding thickness in the range of 4.5 m to 14.7 m while the third layer has resistivity values ranging from 1156.40Ωm to 3732.70 Ωm with an infinite depth. For the four (4) layered model curves, first layer’s resistivity ranged from 29.50 Ωm to 244.70 Ωm, with a corresponding thickness ranging from 0.8 m to 13.0 m. The resistivity of the second layers ranged between 25.2 Ωm to 183.4 Ωm with a corresponding thickness ranging from 8.0 m to 14.2 m. The third layer resistivity ranged from 119.4 Ωm to 586.7 Ωm with a corresponding thickness ranging from 8.1 m to 20.4 m. The forth layer has a resistivity value ranging from 1318.3 Ωm to 3240.9 Ωm with an infinite depth. An integration of both isopach and iso-resistivity maps for both the 3- layer model curves and 4- layer model curves indicates that most of the northwest parts of the study area have low apparent resistivity values and thick overburden while, the southern portion has a little higher resistivity values and shallow overburden, an indication of poor groundwater potential. Future boreholes in the area should reached an expected depth of 50 m to 70 m depth","PeriodicalId":332500,"journal":{"name":"International Journal of Science for Global Sustainability","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128336107","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 extract and fractions were then assessed for their phytochemical contents, antioxidant, and antimicrobial activities. The results showed that saponins, flavonoids, phenol, and tannins were present in all the samples. Also, the ethanol extract had the highest flavonoid (281.15 mgQE/g), phenolic (714.82 mgGAE/g), and tannin (156.54 mgTAE/g) contents, as well as the highest DPPH scavenging activity (95.71%) and total reducing power (1.27). However, among the fractions, butanol fraction showed the highest contents of flavonoids (235.20 mgQE/g), phenolics (413.42 mgGAE/g) and the highest DPPH scavenging activity (93.87 %) while the highest tannin content (86.90 mgTAE/g) and total reducing power (1.06) was observed in the ethyl acetate fraction. The lowest concentration of flavonoid (34.60 mgQE/g) and lowest antioxidant activity was obtained for the hexane fraction while lowest contents of phenolics (102.32 mgGAE/g) and tannins (41.21 mgTAE/g) were both observed in the water-soluble fraction. The most active fraction against both Staphylococcus aureus and Enterobacter cloacae was ethyl acetate. Meanwhile, the ethanol extract, hexane fraction, and water-soluble fractions showed the highest activity against Candida albicans, Salmonella typhi, and Escherichia coli, respectively. This research reveals that the stem bark of Azadirachta indica contains notable antioxidant and antimicrobial properties, making it a promising source for developing potent therapeutic drugs and functional foods.","PeriodicalId":332500,"journal":{"name":"International Journal of Science for Global Sustainability","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126206341","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}
