This paper presents an analysis of the effect of suction/injection on free convective flow past a vertical porous plate under the action of thermal radiation and chemical reaction when heat is supplied to the plate at constant rate. The governing equations are solved using implicit finite difference method. The results are obtained for the velocity, temperature, concentration, skin-friction, Nusselt number, and Sherwood number. The effects of various parameters on flow variables are illustrated physically, and the physical aspects of the problem are discussed. During the course of numerical computation, it was found that the velocity and temperature profiles increase with an increase in suction/injection parameter. Also, the skin-friction and rate of heat transfer increase with increase in radiation parameter and it shows reverse effect in the case of Sherwood number.

Geoelectric investigation was carried out at proposed staff quarters of FCE, Technical Gusau, located along Gusau – Zaria highway, Zamfara State, Nigeria with the aim of delineating the groundwater potentials. 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.

Buck converter is a unidirectional DC-DC power converter that primarily steps down potential difference (PD) of the power bank of batteries or supercapacitors. Electric vehicles usually operate on higher voltage ranging from 45 to 72 volts. However, the electrical accessories of automobiles such as horns, trafficators, radio/players and brake or parking lights were designed to operate on 12 V DC voltage. This necessitates the use of buck converter for stepping down the voltage values to 12 volts. Nonetheless, replacing the converter when the need arises is indeed financially challenging, thus, in such a situation, the vehicles are mostly operated during the day time. Herein, we designed a buck converter using Proteus software and then constructed it with the aim of stepping down the voltage values to 12 volts at a reduced price. The design materials and the construction components used are readily available in most of the electronics shops. An outstanding performance was achieved and results indicated that the designed converter is suitable for use in electric vehicles.

Tinea capitis or scalp ringworm is a fungal skin disorder commonly found in children below 12-year-old. 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.

Metal nanoparticles as a category of nanomaterial are receiving interest due to their wide range of applications including in biomedical fields. Among these nanoparticles, silver nanoparticles are the most extensively studied for medical applications because they have been proven to exhibit excellent activity against a wide range of medically significant pathogenic microorganisms, including bacteria, viruses, fungi, and yeasts. 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. Brine shrimp lethality test of the synthesized AgNPs indicates some level of cytotoxicity with LC50 of 461.850 μg/mL. using biological materials as reducing agents remains best green approach for the synthesis of silver nanoparticles.

Efficient energy supply represents one of the important indicators of a country’s readiness to provide fundamental amenities for its citizens. 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.

Ultracapacitors has now become an integral part of the contemporary energy storage systems. Their uniqueness in optimal power delivery, charge storage capabilities and long cyclic stability (˃105) are what make them attractive to the energy storage industries. Basically, Ultracapacitor consists of two separated electrodes impregnated with an electrolyte. Its performance is largely a function of the chosen electrode-electrolyte materials. The choice of the materials depends on the prevailing conditions at hand and is always at a tradeoff between certain merits and de-merits. In this communication, we reviewed two contemporary materials namely; Transition Metal Oxides and Conducting Polymers with emphasis on the challenges associated with each. This will create an avenue in determining the direction and future perspective of Ultracpacitors materials.

Their uniqueness in optimal power delivery, charge storage capabilities and long cyclic stability (˃105) are what make them attractive to the energy storage industries. Basically, Ultracapacitor consists of two separated electrodes impregnated with an electrolyte. Its performance is largely a function of the chosen electrode-electrolyte materials. The choice of the materials depends on the prevailing conditions at hand and is always at a tradeoff between certain merits and de-merits. In this communication, we reviewed two contemporary materials namely; Transition Metal Oxides and Conducting Polymers with emphasis on the challenges associated with each. This will create an avenue in determining the direction and future perspective of Ultracpacitors materials.","PeriodicalId":332500,"journal":{"name":"International Journal of Science for Global Sustainability","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121963573","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}
