  • The aim of this paper was to determine the utilization of online information resources by undergraduate students in the University of Nigeria, Nsukka. It was undertaken specifically with the objectives of identifying the online information resources used; academic purposes for their use, extent, problems and strategies for improving the academic use of the resources by undergraduate students. Descriptive survey was used as the research design. The population of this study comprises of all 25,657 regular registered undergraduate students in University of Nigeria, Nsukka. The sample for this study comprises 2500 students which is 10% of the population. The results of the study shows that most of the online information resources are not used by the undergraduate students. Just a few of them are highly used. Some of the academic purposes for the use of the resources include to do course assignment and project works and to stay up-to-date on social events. The major problems responsible for the low utilisation of the resources include incessant power failure, limited available computers in the university library, and server's low bandwidth. Based on the findings, maintenance of uninterrupted power supply, provision of enough computers in the library; constant upgrade of server's bandwidth and many more were recommended as the strategies for improving the use of online information resources by undergraduate students in UNN. The implication of this study lies in the fact that solutions to the problems raised would be helpful to the university management, librarians and students in ensuring maximum and adequate provision and effective utilisation of online information a resources in the library.

  • This research paper delved into the availability and utilization of library portal services for research in university libraries in Nigeria. Two research questions and two null hypotheses were formulated to guide the study. A structured questionnaire was used for data collection. The study was carried out in Nnamdi Azikiwe Library, University of Nigeria Nsukka (UNN) and Felix Aghagbo Nwako Library, Nnamdi Azikiwe University Library (UNIZIK), Awka. A total of 70 professionals (librarians and system analysts) in these libraries supplied data for the study. Data collected was analyzed using mean and standard deviation. These were used to answer the research questions while the null hypotheses were tested using t-test statistic at 0.05 level of significance and 68 degree of freedom. Major findings showed that portal services available in the library showed that the areas of availability of library portal services in Nnamdi Azikiwe Library, U.N.N. includes Agriculture, Health Sciences, Engineering, Environmental Sciences and information about institution, Social Sciences, Arts and Humanities, Natural Sciences. In Festus Aghagbo Nwako Library, Awka, the areas of Portal Library Services include Career Development, Federal Government Programs, Environmental Sciences, Biological Sciences, Social Sciences, Arts and Humanities, Engineering, and Health Sciences. Findings on extent of utilization of portal services available in the libraries indicated that portal services are utilized to a low extent in the university libraries. Furthermore, librarians did not significantly differ in their opinions on the availability of library portal services and on the extent of utilization of library portal services in the libraries under study. It is therefore recommended that provisions should be made by the universities and library management to provide and update required portal services in addition to creating enabling environment for enhanced access and utilization of these services. The governments must make an effort to provide funds for policy implementation, necessary technology training for librarians and users, and develop general information infrastructure.

  • Nanoparticles are known for their outstanding properties such as particle size, surface area, optical and electrical properties. These properties have significantly boasted their applications in various surface phenomena. In this work, calcium oxide nanoparticles were synthesized from periwinkle shells as an approach towards waste management through resource recovery. The sol gel method was used for the synthesis. The nanoparticles were characterized using X-Ray diffractometer (XRD), Fourier Transformed Infra-Red Spectrophotometer (FTIR), Brunauer Emmett Teller (BET), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and ultra violet visible spectrophotometer (UV-visible). While DLS and SEM underestimate the particle diameter, the BET analysis reveals surface area of 138.998 m2/g, pore volume = 0.167 m3/g and pore diameter of 2.47 nm. The nanoparticles were also employed as an adsorbent for the purification of dye (methyl orange) contaminated water. The adsorbent showed excellent removal efficiency (up to 97 %) for the dye through the mechanism of physical adsorption. The adsorption of the dye fitted the Langmuir and Temkin models. Analysis of FTIR spectrum after adsorption complemented with computational chemistry modelling to reveal the imine nitrogen group as the site for the adsorption of the dye unto the nanomaterials. The synthesized nanomaterials have an average particle size of 24 nm, showed a unique XRD peak and is thermally and mechanically stable within the investigated temperature range (30 to 70 ℃).

  • This study is on capacity building and attitude to work of librarians in Edo State public libraries, Nigeria. Investigation was on the capacity building programs in the Edo State public libraries, the levels of librarians' awareness and participation in the programs, methods of building the capacity programs, influence on the librarians' attitudes to work and factors militating against the programs. Descriptive survey design was adopted for the study and the entire population of 23 librarians were used. Results indicate that the capacity building programs in the library include computer literacy skills, online public access catalogue (OPAC), Internet collection management and general trends in librarianship. The methods used in building the capacity programs in the library include conferences, workshops/seminars, on-the-job and internally organized courses. Respondents indicated very low level of participation in the programs and a negative influence of the programs on their attitudes to work. Various problems were identified as militating against the capacity building programs and solutions were suggested.

  • A total of 69 ovaries were collected from 345 camels slaughtered in Maiduguri abattoir, North-Eastern part of Nigeria, to study the influence of season on ovary weight and corpus luteum count in the dromedary (single humped) camel (Camelus dromedaries). Right ovary was significantly heavier (p<0.01) and had more follicular fluid than the left. Although corpus luteum count increased gradually throughout the study period, no camel had 3 active corpora lutea and only 53 out of the total number had two. Ovarian activity seem to be higher in the cold dry harmattan season, November/December, than during the warmer post rainy season, September/October. These periods can be exploited by farmers, especially peasants who rely heavily on natural mating, to obtain greater conception rates and reduce the chance of failure during mating.

  • The distributional pattern of the bast fibres strands or bundles in the stems of Sida species represented in Nigeria is studied. Three major patterns of arrangement are recognized, namely aggregation of fibre strands into units with wedge-shaped, or triangular, rectangular, rhomboidal, square and trapezoid outlines; serial arrangement of fibre strands into rings or circular, ovoid, semi-circular or crescentic rows; and intermediate pattern in which both fibre strands-aggregates and serial rows of strands patterns are combined. The first pattern is found in S. linifolia, S. urens and S. scabrida, the second in S. cordifolia, S. pilosa, S. ovata, S. rhombifolia and S. spinosa, and the third in S. garckeana, and S. acuta. A dichotomous key based on these features is presented. Dimensional characteristics of the bast fibre cells are also given.

  • 나이제리아의 middle belt지역의 2개 저수지와 3개 하천에서 Aspatharia sinuata의 생장양상을 조사하였다. 가장 생장이 빠른 곳은 Oyun저수지와 Agbuur강이었으며, 가장 느린 곳은 Asa저수지와 Oyun강이었다. Walford plot에 의한 분석결과에 의하면 이 조개의 이론적 최대 길이는 Asa저수지가 7.39, Oyun저수지 9.65, Oyun강 6.75, Odo-Otin강 7.60, Agbuur강 9.86이었다. 일반적으로 생장은 초기 2년 사이가 빨랐고, 그 후는 생장속도가 낮아졌다. Asa저수지에서의 방사실험 결과에 의하면 패각에는 주생장선이 1년에 하나씩 형성되는 것으로 나타났다. 그리고 연례적인 수위저하와 그로 인한 하면 및 투명도의 감소가 이 조개의 생장을 억제하는 주요인이 되는 것으로 보였다.

  • The intricacies of web development have orchestrated a paradigm shift in academic libraries. The study explored literature on the status of automation of academic libraries and web development in Nigeria. It was established that the functions of library management software are abysmally under-utilized in academic libraries in Nigeria, thus, progression of automation projects remain a swinging pendulum. The paper, therefore, recommends that librarians should acquire the relevant training and plan strategically for all automation projects aimed at incorporating the intricacies of the web and ICTs into library services to fully utilize the functions of the library management systems in line with web developmental stages, thus, be able to compete globally.

  • Media utilization in colleges of education in Nigeria is compulsory to train pre-service teachers. Psychological variables (emotional intelligence, and self-efficacy) and media improvisation were investigated on media resources utilization among lecturers in colleges of education in the South-West, Nigeria. The descriptive design was adopted and multi-staged procedure was used to select 812 (493 males; 319 females). Emotional intelligence (r = 0.79), media improvisation (r = 0.71), self-efficacy (r = 0.85 and media resources utilization r = 0.96) scales were used for data collection. The data were analyzed using descriptive statistics and Pearson product moment at 0.05 level of significance. The level of emotional intelligence, self-efficacy and media improvisation were high. Significant relationship existed among: emotional intelligence (r = 0.42), Media improvisation (r = 0.46) and Teaching self-efficacy (r = 0.31) to media resources utilization. It recommended that lecturers' emotional intelligence, self-efficacy and media improvisation are to be promoted in colleges of education.
