The study area lies in the Basement Complex region of Northern Nigeria and it is situated on Latitude 12o819.64”N to 12o08’24.65’’N and longitude 06o43’28.65’’E to 06o43’37.25’’E with an area coverage of 500 m by 500 m. Vertical Electrical Sounding (VES) technique was employed using Schlumberger array pattern. A total of thirty-six (36) VES points were sounded on Six (6) grided profiles(A-F) separated by 100 m apart with inter VES spacing of 100 m, The VES results depict two distinct curve types namely; H-type and A-type. The results also reveal three distinct geoelectric layers: the top layer, weathered/fractured layer and fresh basement. The top layer has resistivity, depth and thickness range of 10.4 – 158.8 Ωm, 0.4 – 3.6 m and 0.4 – 3.6 m respectively. The second layer has ranges of: resistivity, 6.3 – 525.3 Ωm; depth, 1.4 – 20.8 m, and thickness, 1.0 – 20.4 m. The third layer has resistivity values range of 278.6 – 2726.5 Ωm, its depth and thickness are not defined (to infinity). Seven VES stations (A3, A4, B4, C3, E2, F2 and F5) were delineated for groundwater potential having weathered/fractured resistivity varying between 37.4 and 121.1 Ωm. Depths range were found from 7.9 – 20.8 m and thickness varying between 6.6 and 20.4 m. The results of the study implies that the area has a good groundwater potentials.","PeriodicalId":332500,"journal":{"name":"International Journal of Science for Global Sustainability","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114526422","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 management of ringworm by mean of synthetic drugs continue to face setback as result of antibiotic resistance being exhibited by the disease-causing fungi. Mitracarpus hirtus (L) is a weed plant found on gardens, farms and fields with wide geographical distributions. Pharmacological studies of the plant show its potent antifungal potentials as it is used traditionally for the treatment of skin diseases. The aim of this preliminary study is to examine the antioxidant activities and inhibitory properties of various solvent extracts of M. hirtus leaves against Tinea capitis by standard procedures. The in vitro antioxidant activities show that all extracts possess moderate radical scavenging properties with IC50 values of 159.12±0.48µg/mL, 832.48±64.53µg/mL, 547.68±12.3553µg/mL and 168.41±5.0 µg/mL for Aqueous Residue, n-hexane, chloroform and ethylacetate extracts respectively. Considerable inhibitory effect on the growth of Tinea capitis was observed from the zone of inhibitions of the extracts with ethylacetate fraction exhibiting highest inhibition as the concentration increases. This study shows the potential of M. hirtus to inhibit the growth of tinea capitis. An extensive research is recommended in order to isolate the compounds responsible for the observed activities of the plant.","PeriodicalId":332500,"journal":{"name":"International Journal of Science for Global Sustainability","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128047144","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}

Forty (40) respondents were used as the pilot study that comprises of six (6) science education lecturer and thirty-four post graduate student of the same department. Sixty-three undergraduate students were randomly selected as the sample population of the study from science education department. A structure questionnaire was design that consist of ten items for data collection using Linkert scale and the result was analyses using frequency counting, mean and standard deviation and t-test at P>0.05. From the result it was observed that repositioning teaching and learning process using practical process is inevitable and that the teacher should ready to adopt practical as one of the cardinal points to teach some of the recommendation proffer includes giving awareness to the need for repositioning teaching and learning of science through practical oriented process and prompt adequate financing of the practical for better understanding of scientific phenomenon.","PeriodicalId":332500,"journal":{"name":"International Journal of Science for Global Sustainability","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123448543","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}

In this work, silver nanoparticles were biogenically synthesized using the stem bark extract of Stereospermum kunthianum Cham as capping agent. Physicochemical properties, antioxidant activity, antimicrobial properties and in vitro cytotoxicity of the synthesized AgNPs were studied following standard procedures. UV-Vis studies show broad absorbance peak of the nanoparticles between 430 and 450 nm, SEM image shows that some of the synthesized nanoparticles are near spherical shape with many of the particles appear to have irregular shapes while the material average crystalline size from the XRD analysis was 27.878 mm. The synthesized AgNPs exhibits moderate antioxidant activity with IC50 value of 124.84 μg/mL. Among the microorganism tested, the AgNPs shows more activity against Staphylococcus aureus than Salmonella typhi and Candida albicans.

It similarly indicates the possibility of industrial growth associated with a nation of interest. In Nigeria today, energy supply is greatly insufficient and the government’s approach for handling the situation remained inefficient. Therefore, both scientific and policy based researches with focus on enhanced energy production are desirable for national interest. This specific manuscript targeted a discussion on how the abundant natural resources in Nigeria could be transformed into industry based catalysts and successfully applied for both biomass and fossil fuels valorization. It was successfully demonstrated herein that fly ash from coal processing, waste materials from cement manufacture, rock-based natural zeolites and many other industrial wastes could be converted into affordable catalysts for utilization in energy production via catalysis. Emphasis was also placed on the need for research intensification on catalyst development, characterization with advanced methods and evaluation at laboratory and industrial scales. This way, the challenges of energy production in Nigeria would be reduced effectively.","PeriodicalId":332500,"journal":{"name":"International Journal of Science for Global Sustainability","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127619662","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}
