- ItemThe use of bigdata in the management of library resources: Nigeria university expriences(2024-07) M. L. Akanbi; Kabir Alabi Sulaiman; Maliq Hammed Omolola; Bilqees Jumia NallahServices of libraries have to be accessible to all members of the community; this requires well situated library infrastructure, facilities and information resources as well as relevant technologies. Therefore, this study explored the use of big data in the management of library resources in university libraries. Four objectives were proposed for the study to describe the use of bigdata in managing resources of university library. In addition, ethical concern related to the use of bigdata was also identified in the paper. Descriptive literature review was used as methodology. The study conclude that Bigdata as a tool in university libraries is an important mechanism that is meant to protect library information resources for use. The nature of the library resources call for more protection especially resources are ICT in nature. However, the important of Bigdata in any organization including library become an imperative to resources management. The nature of services delivery in this present age in university library calls for the use of Bigdata so that right information resources can be provided to right people at tight time and place. Based on the concluding part, the study recommends that awareness should be provided by university libraries and management on the opportunities of Bigdata to library clienteles and training, conference and workshop should be orgnise by library and university management in order to equip library personnel with the needed skills and knowledge on better use of Bigdata in service provision.
- ItemPhytoavailablility and fractionation of cadmium and lead in vegetable farm soils in Ilorin, north-central, Nigeria(Ife Journal of Science, 2021-05-03) P.O. Ben-Uwabor G.K. Olawepo C.O. Ogunkunle O.P. FatobaHeavy metal dynamics, bioavailability and fractionation are of great importance to measure soil toxicity, remediation strategies and availability in soil. However, reports showed that not much has been done to evaluate these parameters in vegetable farm soils in Ilorin metropolis. These parameters aid in assessing and extent of heavy metal viability in soil. Therefore, soils were collected from major vegetable farms in Ilorin metropolis, sorted, air-dried, ground, and pretreated for further analysis. Thus, this study investigated the bioavailable Cd and Pb and their fractionation in vegetable farm soils in Ilorin metropolis. These experiments were conducted by single extraction procedure, sequential extraction and Atomic Absorption Spectrophotometry, alongside analysis of some key soil properties. The results showed that the soil pH ranged from 6.62±0.04 to 7.18±0.03, organic matter 2.05 ±00% to 3.50±005% and cation exchangeable capacity 3.68±0.02 cmolc/kg to 8.63 ±0.03 cmolc/kg. The target heavy metals in the sampling areas were potentially bioavailable with phytoavailable concentration ranges of 0.00±0.00 mg/kg to 0.67±0.14 mg/kg for Cd and 0.33±0.03 mg/kg to 6.25±0.25mg/kg for Pb. The target heavy metals showed a high viability of the soluble and exchangeable form in most soils and in both seasons which would greatly contribute to their availability to plant uptake and soil toxicity. There is also a threat of oxidization of the potentially available Cd and Pb in other forms due to pH ranges of most of the studied soils. Therefore, vegetable farm soils in Ilorin metropolis are polluted with Cd and Pb and may have high risk of causing human health problems when vegetables grown on the soils are consumed; which calls for remediation of most of the soils.
- ItemHeavy Metal Uptake Responses in Plants Grown on Crude Oil-Polluted Soils as Prospects for Phytoremediation(African Journal of Applied Sciience and Environmental Management, 2020-07-06) OLAWEPO, GK; 1OGUNKUNLE, CO; 1FATOBA, PO; 1ANIMASAUN, DA; 2BENUWABOR, PO; 3DANZAKI, MMThe demand and utilization of petroleum products have re-energized its exploration and exploitation globally and this upsurge in world production, refining and distribution of petroleum products have brought with it various problems of environmental pollution, which have effects on the ecosystems. Twenty (24) polyethylene pots each containing 7 kg of sandy loam soil mixed with 50 ml of crude oil, were arranged in the Botanical garden of the University of Ilorin, Nigeria, to assess their ability to phytoextract heavy metals in Crude oil-polluted soil. Seeds of Amaranthus hybridus L., Tithonia diversifolia, Abelmoschus esculentus L. and Zea mays were sown in polyethylene containers containing 7 kg of contaminated or Control soil. The containers were arranged in a complete randomized design. Plants were left to grow for two months with regular watering. Plants were harvested, separated into roots and shoots and oven-dried to constant weight. The experimental plants have been able to reduce the concentration of Cu in both soils by about 45% to 85%, Cr in the soil by 92.08% to 96.72%, as the residual concentration varied between 66.00 mg/kg and 99.00 mg/kg, Cd in the soil was reduced to 4.00 mg/kg and 17 mg/kg which represented 96.8% and 86.4% reduction. Tithonia had the highest Pb reduction in crude oilpolluted soil. Ni concentration was reduced by 85.84% by Tithonia planted in crude oil-polluted soil, 94.59% by Amaranthus hybridus planted in Control soil. These show that all the test plants were good phytoextractors of the metals.
- ItemPractical Cataloging and Classification Training by Library and Information Science Users Education at Kwara State University Library, Nigeria(Libraries at University of Nebraska-Lincoln, 2024-04) Abdrahman .A. MOUSTAPHA (CLN/NLA) Kwara State University, Nigeria.; Julius Babatunde ODUSINA (Pan African College of Education, Offa)Purpose The study examined the cataloging and classification training of users in library and information science and their use of library catalogs at the Kwara State University Library, Nigeria. Training is a vital necessity for performing any professional responsibility. Therefore, the trainee's actions towards the training program cannot be affected. Design/methodology/approach The study adopted a descriptive research approach. It surveyed a sample of 250 university library users selected from a population of 515 through random sampling. The findings Library and Information Science users at Kwara State University Library, Nigeria, have a negative perception of the practical study of cataloging and classification as a course of study and a weak inclination toward using library catalogs. Scheme tools available for practical cataloging and classification are Dewey, Library of Congress Classification, and Sears List of Subject Headings, Anglo-American Cataloguing Rule, and Catalog Cards. Users in library and information science have the cataloging and classification skills and artifacts they have acquired from practical training, but some of their problems in studying cataloging and classification include the lack of a cataloging and classification laboratory, insufficient indexing and classification tools, and insufficient time allocated for study. Practical learning of cataloging and classification, insufficient cataloging and classification textbook materials to guide users, and outdated practical catalog and classification tools used by professional catalogers
- ItemTRAINING LIBRARY AND INFORMATION SCIENCE STUDENTS IN KWARA STATE UNIVERSITY, MALETE(A Journal of NLA IT Section, 2023) Abdulsalam Abiodun Salman Yahaya Aliyu Ismaila and Florence Olabisi AjaniThe purpose of this study is to examine the impact of training on library and information science students in Kwara State University, Malete. The objectives of this study includes finding out the challenges faced by library and information science lectures in training students, identified attitude of library and information science lecturers in relation to the profession, among others. The research design adopted in this study was descriptive survey design. The population of the study consist of 14 respondents. The sampling technique that was used in this study was the census enumeration technique. Finally, recommendation were offered which include that, the government institution and relevant authorities should provide adequate funding for the education and training of Library and an information science programs to cater for efficient learning materials professionalism and enabling environment, sensitization and courage of service should be given to libraries so as to be proud of the profession, library and information science profession should be made attractive to improve and achieve full utilization of the profession and provision of ICT and trained qualified staff.
