ARTIFICIAL INTELLIGENCE ADOPTION AND UTILIZATION BY LIBRARIANS IN UNIVERSITY LIBRARIES IN KWARA STATE, NIGERIA

The study investigated how librarians working in various university libraries in Kwara State, Nigeria, adopt and use artificial intelligence. The study raised four research goals as well as four research questions. A descriptive survey method and random sampling techniques with 450 randomly selected librarians from Kwara State Universities, Nigeria, were used for the research. Five research assistants were trained on how to contact respondents and secure their consent before distributing the structured questionnaire designed by the researcher, who assisted in the tool distribution process. The researcher was able to retrieve 410 copies of the 450 questionnaires that were given to the respondents. However, the rate of return was 91%, which is a respectable amount. A self-designed questionnaire was used to elicit responses from the respondents, and a simple percentage was adapted for data analysis. The results showed that there was little adoption of AI in university libraries in Kwara State, Nigeria. The research also reveals that security scanning devices at the entrances and exits of university libraries are the most prevalent AI systems, while other AI systems such as bots, chatbots, face recognition, touch recognition, RFID technologies, humans, AI classification tools, machine-readable catalogs, and not smart AI features are still missing from the Kwara State University libraries. A self-designed questionnaire was used to elicit responses from the respondents, and a simple percentage ratio was adapted for data analysis. The findings revealed that AI has received minimal attention in university libraries in Kwara State, Nigeria. According to the study, the most common AIs are security scanning equipment at university library entrances and exits, followed by robotics, chatbots, face recognition, and touch recognition. RFID technologies, humanoids, AI classification tools, machine-readable catalogs, and AI smart features are still lacking in Kwara State\u27s university libraries. The results of this study also indicate that librarians in a university library are aware of the many ways in which artificial intelligence can be applied to provide services. The results of the study indicate that obstacles to adoption include significant disruption caused by artificial intelligence in traditional library services, a lack of skills and a need for training prior to adoption, irregular power supply, and a lack of adequate infrastructure for adoption, among other problems. The study recommended the need to organize training for librarians to enhance their skills in using artificial intelligence to provide services, and the university administration and libraries should commit and provide the necessary support for the adoption of artificial intelligence by providing the necessary infrastructure to ensure its rapid implementation

ADOPTION OF ARTIFICIAL INTELLIGENCE TO IMPROVE LIBRARY SERVICE DELIVERY IN ACADEMIC LIBRARIES IN KWARA STATE, NIGERIA

Due to the increasing presence of artificial intelligence (AI) in developed countries, this paper examines the adoption of AI for effective library services in academic libraries in Nigeria. The paper defines artificial intelligence while chronicling its history. He also identified the advantages of adopting artificial intelligence in academic libraries, which include ease of use, endless functionality, and the ability to perform complex work, among others, and the challenges faced by library management towards adopting artificial intelligence, which include financial uncertainty, job loss, and technological defects, among others. The paper concluded that adoption of AI in academic libraries sets a new level of efficient and effective library service delivery, but adoption in developing countries such as Nigeria is low due to some identified challenges. The paper recommended that government and library management should come together to suggest the way forward for academic libraries in terms of meeting the latest standard for the use of AI in libraries; library staff must undergo training and retraining in the use of artificial intelligence in providing library services, among other things

Acute and Sub-chronic Toxicity Studies of Methanol Leaf Extract of Cassia singueana F. (Fresen) in Wistar Rats

The aim of this study was to evaluate the toxicity profile of methanol leaf extract of Cassia singueana (fabaceae) in wistar rats. Fresh leaf of the plant was shade dried and pulverized to powder after which it was subjected to maceration with methanol and 9.2% yield was obtained at end of the extraction process. An acute toxicity study was carried out using lork’s method and sub-chronic toxicity study was also carried out using OECD guideline. In the acute toxicity study, the first phase of the method, nine (9) wistar rats were randomly divided into three groups (1-3) of three (3) animals each and they received 10,100 and 1000 mg/kg (po) Cassia singueana methanol leaf extract respectively and in the second phase four (4) animals were divided into four groups of one animal each which received 1200, 1600, 2900 and 5000 mg/kg (po) of extract respectively. In the sub-chronic toxicity study twenty (20) animals were divided randomly into four group each containing five animals, the first, second, third and fourth group received distilled water, 200, 400 and 800 mg/kg extract (po) respectively. There was no mortality observed in phase 1 of acute toxicity and in phase II there was mortality at 2900 and 5000 mg/kg group. The oral administration of methanol leaf extract of Cassia singueana for 28 days did not produce significant alteration in the renal function indices. The histological section of the rats indicates normal glumeruli and regular renal tubules. Also, this study reveals no significant increase in the level of liver enzyme. Also, the histology section reveals normal central vein and regular hepatocyte separated by sinusoid. The haematopoetic indices reveal no destruction of Red Blood Cell and no change in the rate of production of the RBCs and other haematopoetic parameters. The histology of the rat’s brain revealed no deleterious effect. It can be concluded that, the methanol leaf extract of Cassia singueana is relatively non- toxic

Phytoremediation of Contaminated Soil Using Maize (Zea mays) and Mycorrhiza Inoculation

The phytoextracting capacity of maize (Zea mays) on soil contaminated with brewery waste was determined. The method used was based on the responses of the maize plants grown on four different soils (inoculated and uninoculated, with and without brewery waste) tagged M+B+, M-B+, M+B- and M-B-. These were analysed for mid-rib growth, neurosis, and heavy metals uptake in the plant in addition to soil and pH analysis. Results showed that maize (Zea mays) planted on soil of type M+B+ had a rapid increase in mid-rib size (55.3cm) while the plant grown on the control sample had the lowest size (47.0cm). There were initial increases in plant with neurosis in the inoculated samples which either stabilised or increased while the number in the uninoculated samples reduced with time. The plants grown on inoculated soil had greater heavy metal uptakes of 54–83% except for Cd where the uptake was 33–40% while those grown on uninoculated soil had metal uptakes of 19–52% except for Zn where the uptake was 80–81%. The investigation concluded that maize has the capacity of removing heavy metals from brewery waste and suggested revegetation of the soil to reduce wind and water erosions. &nbsp

Economic policy uncertainty and the co-movement between REITs and exchange rate

The REITs market has attracted a lot of interest among the academic, policymakers, and market participants. The linkages between REITs and macroeconomic and financial variables have been adequately explored in the literature, with more emphasis on linear models. This study expands the frontier of knowledge by examining the role of uncertainty in the comovement/spillover between REITs and the currency markets. Some interesting results were observed. First, using the Diebold and Yilmaz (2012) spillover test, we find that there is strong connectedness between the REITs and currency markets. Second, the BDS test shows that nonlinearity is a very crucial factor to be put into consideration when examining the role of EPU in affecting the interactions between REITs andexchange rate markets. Third, the non-parametric causality-in-quantile test confirms that the connectedness between the markets and EPU is stronger around the lower and middle quantiles. These results have important policy implications for policymakers and market participants. The study also offers suggestions for future research

Development and Evaluation of an Interactive Instructional Package for Teaching Engineering Graphics Skills

Exposure to modern pedagogical approaches and methods with appropriate instructional media can enhance the development of high-level critical thinking and technical skills. This study examined the development of an interactive instructional software package for teaching engineering graphics and evaluated its relative effectiveness on second-year undergraduate engineering students' academic achievement, skill transfer, and retention. In this study, the quasi-experimental, pre-test, post-test, control group design was employed. 45 research participants were sampled, employing two-stage stratified sampling technique, which comprises the simple random sampling to assign students into three groups from the study population and systematic sampling with k = 3 to select 15 students from each group to a control group and experimental groups A and B. The control group was exposed to conventional classroom instruction (CI), group A to computer-aided instruction (CAI); and group B to conventional and computer-aided instructions (CCAIs). A computer-aided learning package on engineering graphics was developed using the Camtasia software package, which served as the treatment instrument. The pre-test and post-test data used for analysis stemmed from a validated Engineering Graphics Achievement Test instrument. Analysis of covariance and Sidak post hoc test statistical analysis of the groups' performance provided the results on the comparative effects of the treatment conditions. Findings indicated significant differences between the academic achievement, skill transfer, and retention of students, exposed to CCAIs, and CI or CAI strategies. When used together, a significant improvement in students' academic achievement, transfer, and retention of engineering graphics skills occurred than either the CI or CAI strategy used alone

Foreign Body in Frontal Sinus: Case Report

A foreign body in the frontal sinus is extremely rare and most cases are related to maxillo-facial trauma. Sixty eight year-old female patient was admitted to our clinic with left nasal obstruction and left frontal pain. A polypoid mass was detected at the left middle meatus by endoscopic examination. Loss of frontal sinus aeration and soft tissue density, especially at the anterior ethmoid region, were observed in the computed tomography scans. The history of the patient was unremarkable except for a neurosurgical operation due to a benign frontoparietal tumour in 1998. Fronto-ethmoidectomy was performed with an endoscopic transnasal approach under general anaesthesia. The histopathological examination was reported as “bone-wax”. The patient had no problem in the 3rd postoperative month. This rare case is presented with clinical and radiological findings and a picture of the foreign body

Farm Practical Training and Job Aspiration of Undergraduates of Agriculture in Universities in Kwara State Nigeria

The study investigated whether Farm Practical Training (FPT) is significantly associated with job aspiration of Undergraduate students comparing results of empirical evidence between two Universities in Kwara State, Nigeria. Specifically, students preferred courses of study were identified, and their attitude towards FPT and job aspiration were determined. 120 final year students who recently completed the FPT were selected from the two Universities through multistage sampling. Average age of student was 23.5 years with standard deviation of 2.4. Less than half (40%) preferred agriculture as course of study, while 38% preferred science and 5% medicine. About 32% decided to stay on in agriculture after admission because it is deemed prestigious, 13% due to being last available opportunity to gain admission and 17% because of its entrepreneurial potentials. Many (69.8%) aspired for agriculture/farming related job, while 12% aspired to work in agro-allied industries. While many (45.8%) had favorable attitude towards the FPT, comprising 35.0% UNILORIN and 10.8% KWASU students, more (23.3%) of KWASU students had unfavorable attitude towards the FPT compared to 5% UNILORIN students in this category. There was no significant association between students’ attitude towards FPT and their job aspiration in both institutions (UNILORIN χ2=8.07, p=0.62; KWASU χ2=8.60 p=0.38). Although, most of the students aspired to work in agriculture/agro-allied industry, it could not be concluded from the findings of the studies that FPT did significantly influence their job aspiration.

Biofilm formation and cellulose expression by <i>Bordetella avium</i> 197N, the causative agent of bordetellosis in birds and an opportunistic respiratory pathogen in humans

Although bacterial cellulose synthase (bcs) operons are widespread within the Proteobacteria phylum, subunits required for the partial-acetylation of the polymer appear to be restricted to a few γ-group soil, plant-associated and phytopathogenic pseudomonads, including Pseudomonas fluorescens SBW25 and several Pseudomonas syringae pathovars. However, a bcs operon with acetylation subunits has also been annotated in the unrelated β-group respiratory pathogen, Bordetella avium 197N. Our comparison of subunit protein sequences and GC content analyses confirms the close similarity between the B. avium 197N and pseudomonad operons and suggests that, in both cases, the cellulose synthase and acetylation subunits were acquired as a single unit. Using static liquid microcosms, we can confirm that B. avium 197N expresses low levels of cellulose in air–liquid interface biofilms and that biofilm strength and attachment levels could be increased by elevating c-di-GMP levels like the pseudomonads, but cellulose was not required for biofilm formation itself. The finding that B. avium 197N is capable of producing cellulose from a highly-conserved, but relatively uncommon bcs operon raises the question of what functional role this modified polymer plays during the infection of the upper respiratory tract or survival between hosts, and what environmental signals control its production
