Library Orientation and Information Literacy Skills as Correlate of Scholarly Research of Postgraduate Students in Federal University of Agriculture, Abeokuta

This study focused on library orientation, information literacy skills as correlate of scholarly research of postgraduate students of Federal University of Agriculture, Abeokuta. The university has ten colleges with various departments. A survey research design was adopted for the study. The population of the study comprised the all 1,361 postgraduates in Diploma, Masters and Doctor of Philosophy from the ten (10) colleges in the institution. Out of the population, 900 postgraduates were randomly selected using purposive sampling technique; while data were collected using questionnaire. Findings of the study revealed that there is no library orientation programme for postgraduates at FUNAAB, while the only form of information literacy available to them is the use of computer course. It was also found that information literacy skills of postgraduate are still low given that majority of them either cannot access the library’s online catalogue or its electronic databases without assistance. The study therefore concluded that library orientation and information literacy skills are essential for postgraduates quality research output and recommends for inclusion of library orientation, information literacy and any other user education programmes into postgraduate curriculum. Also, seminars and workshops on the online catalogue and electronic databases for research should equally be periodically organised for postgraduate students

Development and Performance Evaluation of Hausdorff Distance Algorithm Based Facial Recognition System

Securing access to information is of primary concern in many frame of reference including personal, commercial, governmental and military purpose. Computer verifiable biometric such as face provide an attractive means of securing access to information. Earlier algorithms for facial recognition system which includes Linear Discriminant Analysis (LDA), Principle Component Analysis (PCA) andIndependent Component Analysis (ICA) have yielded unsatisfactory result especially when confronted with unconstrained scenarios such as varying illumination, varying poses, expression and aging. This work presents a facial recognition authentication system using hausdorff distance algorithm in combating the highlighted problems. A system camera was employed for capturing images, information was stored using MYSQL database and biometric templates were stored as binary large object (BLOB). The developed system performance was evaluated using False Reject Rate (FRR), False Accept Rate (FAR), and Receiver Operating Characteristic Curve (ROC graph) as performance metrics. Tests were conducted at various threshold values. FRR errors obtained are 20%, 7%, and 2% at 500 threshold value for one-try, two-try and three-try configuration respectively. The system also presented FAR error of 0% at 500 threshold value for all configurations. As threshold value increases, FAR reduces while FRR increases

Gas Chromatography-Mass Spectrometry and Single Nucleotide Polymorphism-Genotype-By-Sequencing Analyses Reveal the Bean Chemical Profiles and Relatedness of Coffea canephora Genotypes in Nigeria.

The flavor and health benefits of coffee (Coffea spp.) are derived from the metabolites that accumulate in the mature bean. However, the chemical profiles of many C. canephora genotypes remain unknown, even as the production of these coffee types increases globally. Therefore, we used Gas Chromatography-Mass Spectrophotometry to determine the chemical composition of C. canephora genotypes in Nigeria-those conserved in germplasm repositories and those cultivated by farmers. GC-MS revealed 340 metabolites in the ripe beans, with 66 metabolites differing (p-value < 0.05) across the represented group. Univariate and multivariate approaches showed that the 'Niaouli' genotypes could be clearly distinguished from 'Kouillou' and 'Java' genotypes, while there was almost no distinction between 'Kouillou' and 'Java,'. Varietal genotyping based on bean metabolite profiling was synchronous with that based on genome-wide Single Nucleotide Polymorphism analysis. Across genotypes, the sucrose-to-caffeine ratio was low, a characteristic indicative of low cup quality. The sucrose-to-caffeine ratio was also highly correlated, indicative of common mechanisms regulating the accumulation of these compounds. Nevertheless, this strong correlative link was broken within the 'Niaouli' group, as caffeine and sucrose content were highly variable among these genotypes. These 'Niaouli' genotypes could therefore serve as useful germplasm for starting a Nigerian C. canephora quality improvement breeding program

Heavy Metal Contamination of a Dumpsite Environment as Assessed with Pollution Indices

Indiscriminate refuse dumping in and around Ado-Ekiti combined with improper management of few available dumpsites, such as Ilokun dumpsite, posed the threat of heavy metals pollution in the surrounding soils and underground water that needs assessment using pollution indices. Surface soils (0-15 cm) were taken from the centre of Ilokun dumpsite (0 m) and environs at different directions and distances during the dry and wet seasons, as well as a background sample at 1000 m away, adjacent to the dumpsite at Ilokun, Ado-Ekiti, Nigeria. The concentration of heavy metals used to calculate the pollution indices for the soils were determined using Atomic Adsorption Spectrophotometer. The soils recorded high concentrations of all the heavy metals above the background concentrations irrespective of the season with highest concentrations at the 0 m except Ni and Fe at 50 m during the dry and wet season, respectively. The heavy metals concentration were in the order of Ni > Mn > Pb > Cr > Cu > Cd > Fe during the dry season, and Fe > Cr > Cu > Pb > Ni > Cd > Mn during the wet season. Using the Contamination Factor (CF), the soils were classified to be moderately contaminated with Cd and Fe to very high contamination with other metals during the dry season and low Cd contamination (0.87), moderate contamination with Fe, Pb, Mn and Ni and very high contamination with Cr and Cu during the wet season. At both seasons, the Pollution Load Index (PLI) indicates the soils to be generally polluted with heavy metals and the Geoaccumulation Index (Igeo) calculated shown the soils to be in unpolluted to moderately polluted levels. Enrichment Factor (EF) implied the soils to be deficiently enriched with all the heavy metals except Cr (7.90) and Cu (6.42) that were at significantly enrichment levels during the wet season. Modified Degree of Contamination (mCd) recorded, indicated the soils to be of very high to extremely high degree of contamination during the dry season and moderate degree of contamination during the wet season except 0 m with high degree of contamination. The concentration of heavy metals in the soils combined with some of the pollution indices indicated the soils in and around the Ilokun Dumpsite are being polluted with heavy metals from anthropogenic sources constituted by the indiscriminate refuse dumping

Epidemiologic and Clinical Features of Lassa Fever Outbreak in Nigeria, January 1–May 6, 2018

Lassa fever (LF) is endemic to Nigeria, where the disease causes substantial rates of illness and death. In this article, we report an analysis of the epidemiologic and clinical aspects of the LF outbreak that occurred in Nigeria during January 1–May 6, 2018. A total of 1,893 cases were reported; 423 were laboratory-confirmed cases, among which 106 deaths were recorded (case-fatality rate 25.1%). Among all confirmed cases, 37 occurred in healthcare workers. The secondary attack rate among 5,001 contacts was 0.56%. Most (80.6%) confirmed cases were reported from 3 states (Edo, Ondo, and Ebonyi). Fatal outcomes were significantly associated with being elderly; no administration of ribavirin; and the presence of a cough, hemorrhaging, and unconsciousness. The findings in this study should lead to further LF research and provide guidance to those preparing to respond to future outbreaks

Increase in Lassa Fever Cases in Nigeria, January–March 2018

We reviewed data pertaining to the massive wave of Lassa fever cases that occurred in Nigeria in 2018. No new virus strains were detected, but in 2018, the outbreak response was intensified, additional diagnostic support was available, and surveillance sensitivity increased. These factors probably contributed to the high case count
