This study aimed to detect microorganisms in dump-site soils coupled with testing the susceptibility of the detected microorganisms to selected antibiotics Soil samples were collected from five separate dump-sites in Ogbomoso, Oyo State, Nigeria. From the soil samples that were collected, eight species of bacteria and eight species of fungi were isolated. The bacterial and fungal derived from the collected soil samples were tested for antibiotic susceptibility using the conventional disc diffusion method. Results obtained indicate that the microbial loads varied between 1.7 and 4.8 x 105 CFU/g for fungal isolates while it varied from 1.0 to 8.0 x 105 CFU/g for bacterial population. Fungal isolates;Alternaria alternata, Candida albicans, Rhodotorula minuta, Fusariun oxysporum, Aspergillus flavus, Aspergillus tamarii, Fusarium solani and Penicillium digitatum were detected while bacterial isolates; Bacillus subtilis, Bacillus cereus, Staphylococcus epidermis, Clostridium sp., Acetobacter sp., Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa were equally detected from the dump-sites’ soil samples. The bacterial species tested were completely resistant to cefuroxime, but completely susceptible to gentamicin and ofloxacin. At varying doses, the fungal isolates demonstrated resistance to and susceptibility to griseofulvin, itraconazole, and ketoconazole.Based on the results of this study, antibiotics such as gentamicin and oflaxacin should be considered first line of defense against infections caused by both soil-borne Gram-positive and Gramnegative bacteria ","PeriodicalId":479620,"journal":{"name":"Dutse Journal of Pure and Applied Sciences","volume":"67 28","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140664134","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}

This has become a key subject, especially in Nigeria. Consequently, automobile trailing schemes are gradually becoming evident amongst common users in the transport sector in most major metropolises. This paper aims to showcase a developed Android-based application system for vehicle trailing schemes that integrates Google Maps real-time features, the “Global Positioning System (GPS), and employs the Global System for Mobile Communication (GSM)” technology. The GPS component is a space-based navigation system that runs on location and time data at all times, irrespective of place and time on the globe, provided there is a line of sight to any of the four or more GPS satellites. The time and location are displayed, utilising Google Maps, which serves as an interface with the application so that the user will be able to constantly monitor moving vehicles via the smartphone. Presented here are the designed model and the experimental outcome of the automobile trailing system that verifies the possibility of the system trailing the movement of vehicles from one location to another at any given time, as well as an interactive Graphical User Interface (GUI) for the Smartphone application.

The percentage of the contribution of dry term (Ndry) and wet term (Nwet) to radio refractivity and refractivity gradient were investigated. The findings indicated that radio refractivity was higher during the rainy season (August) and lower’during the dry season (February), with a maximum mean value of 350.8733 N-units and a minimum mean value of 284.1975 N-units, respectively, found in those months. The wet term contributes to the significant fluctuation of the radio refractivity, whereas the dry term makes up 76.03% of the total value.

The soluble portion of the extracts was given at working doses of 10, 20, and 30% of the LD50 to the corresponding experimental animal groups (i.e low, middle, and high dosages accordingly). Findings from Sansevieria trifasciata and S. liberica’s phytochemical screening indicated the existence of secondary metabolites like terpenes, alkaloids, cardiac glycosides, and tannins. When given intraperitoneally, the LD50 of S. trifasciata and S. liberica were 387.30 and 353.55 mg/kg, respectively. The plant extracts’ soluble fraction was given intraperitoneally (i.p.) by injection as well as orally. The phlogistic egg-albumin-induced inflammation significantly decreased (p<0.05) according to the results. However, the development of a strong anti-inflammatory drug with low toxicity and an improved therapeutic index may come from the isolation of these bioactive components.

Distributed sensors in the form of WSNs are used to keep tabs on environmental or physics-related variables. These sensors operate together to send information via the internet to a central location, where it may be used to inform decisions that have real consequences for people's lives. As detecting, processing, and transmitting all take a lot of energy, WSNs are powered by batteries that cannot be replaced during data transmission. Therefore, it is essential to increase the network's durability by reducing the energy consumption of each sensor node. Power consumption problems exist in network's communication routes between the sensor nodes might have disastrous effects on a network that relies on timely data transmission. Since the sensor nodes need electricity to function, losing that power disrupts data transmission and, in most situations, kills the network. A serious issue with WSNs is their rapid loss of energy. Studies have shown that switching the node from active to sleep mode while it is not in use may extend the lifespan of WSNs. Some have argued that a mobile charger should be made available instead of a sensor node with a changeable battery. Even though energy harvesting the practice of drawing power from the surroundings and transforming it into electrical energy has the potential to address this issue, there are situations in which this is not possible. The objective of this study is to design a more energyefficient algorithm for usage by sensor nodes in order to decrease their power consumption. By combining game theory and Grey Wolf Optimisation with the existing Sector Low Energy Adaptive Clustering Hierarchy (LEACH) routing system, a more efficient and effective algorithm was developed called Enhance Game and Grey Wolf Algorithm (EG-GWA).

The formation has been inadequately studied systematically in the light of chemostratigraphy. The existing works on the formation either lack representativeness in terms of the proxies used or are subjective during their division procedures. From the field studies, five (5) samples of sandstone and shale units of the Yolde Formation were collected. The samples were analyzed for both major and trace elements using an X-ray fluorescence machine. The following geochemical parameters were studied; Al2O3, Al2O3/Fe2O3, KO2/Al2O3, TiO2/Al2O3, CaO, Cr, Rb/Sc, and Zr. From the studies, six (6) chemozones were identified in the Yolde Formation. Transgressive and regressive depositional sequences were observed with a significant sequence boundary of maximum flooding surface which is a time-significant feature. The chemostratigraphic scheme could not only be comparable to the regional sequence stratigraphic scheme but also more objective and higher resolution. This research gives a systematic chemostratigraphic analysis of Yolde Formation, which testifies to the feasibility and potential of the usage of chemostratigraphy for stratigraphic development.

We focused on some acenebased molecular junctions, in which molecules are connected to Au electrodes via anchor groups. The frontier molecular orbitals (FMOs) and charge transport nature of the junction were examined by employing the density functional theory (DFT) in conjunction with the non-equilibrium Green's functional (NEGF) formalism. Particular attention was paid to the anchoring groups (NH2, S, CN, and SH), chemical impurity doping (B, N, and NB), and side groups (-CH3, -NH2, and –NO2). The findings demonstrate that the FMOs can change depending on the dopants or substituents employed. Additionally, it is noted that depending on the materials employed, charge transfer may be p-type or ntype. It is discovered that the molecular junctions have the highest conductivity when cyanides are used as anchor groups. It is therefore the ideal anchor material to utilize with tetracene and pentacene molecules. Understanding and creating n-type or p-typed high conductivity single molecule electronic components can be greatly aided by these discoveries.
