Radio Listening Habits among University Students and Their Attitude towards Programmes (A Study of Redeemers University Students)
Radio plays a very significant role in the society and that cannot be overlooked. The main objective of this study was to conduct a survey on radio listening habits of university students and their attitude to programmes. Survey research method was used through questionnaires to find the listening habit and attitude students have towards radio. Students of Redeemers University were the sample size for this research work; a total number of 400 copies of questionnaire distributed to the students. From this research work, it was discovered that students have an easy access to radio in the campus, but they face difficulty while listening to radio on campus. The programming pattern adopted by radio stations influence students attitude to programmes. Keywords: Attitude, listening habits, Radio, students
Effect of microwave treatment on cooking time, colour, sensory andnutritional properties of Bambara groundnut (Vigna subterranea)
Bambara groundnut is a leguminous crop that currently experiences a low level of utilisation because it is hard-to-cook and difficulty to dehull.
In this study, the effects of different microwaving power of 450, 500, 600 and 750 W and time (0, 30, 60, 120 and 240 s) on cooking time, colour, sensory and nutritional properties of Bambara groundnut using standard methods were investigated. Microwaving generally reduced the cooking time of Bambara groundnut. The cooking time reduced by approximately 28, 46, 52 and 55% when Bambara groundnut was microwaved at 450, 500, 600 and 750 W for 240 s, respectively. Microwaving did not significantly (p>0.05) affect the colour and appearance of the grain. Bambara groundnut had similar lightness values (60.66-63.15), but slightly different a (3.38-5.57) and b values (16.16-19.20) after microwaving. Protein (23.90-26.88%) and carbohydrate (47.85-58.58%) were the major components of raw and microwaved grains. Microwaved grains showed higher digestibility values (approx. 78-85%) compared to the raw Bambara groundnut (approx. 71%). Mean sensory scores revealed that Bambara groundnut microwaved at 600 W for 240 s had comparable acceptability with the control sample. Microwaving can be used to reduce cooking time of Bambara groundnut, improve protein content and digestibility without significantly altering the sensory properties
Molecular characterization of non-aureus staphylococci and Mammaliicoccus from Hipposideros bats in Southwest Nigeria
Bats are not only ecologically valuable mammals but also reservoirs of zoonotic pathogens. Their vast population, ability to fly, and inhabit diverse ecological niches could play some role in the spread of antibiotic resistance. This study investigated non-aureus staphylococci and Mammaliicoccus colonization in the Hipposideros bats at Obafemi Awolowo University, Ile-Ife, Nigeria. Pharyngeal samples (n = 23) of the insectivorous bats were analyzed, and the presumptive non-aureus staphylococcal and Mammaliicoccus isolates were confirmed by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). The isolates were characterized based on antibiotic susceptibility testing and whole-genome sequencing (WGS). Six bacterial genomes were assembled, and three species were identified, including Mammaliicoccus sciuri (n = 4), Staphylococcus gallinarum (n = 1), and Staphylococcus nepalensis (n = 1). All the isolates were resistant to clindamycin, while the M. sciuri and S. gallinarum isolates were also resistant to fusidic acid. WGS analysis revealed that the M. sciuri and S. gallinarum isolates were mecA-positive. In addition, the M. sciuri isolates possessed some virulence (icaA, icaB, icaC, and sspA) genes. Multi-locus sequence typing identified two new M. sciuri sequence types (STs) 233 and ST234. The identification of these new STs in a migratory mammal deserves close monitoring because previously known ST57, ST60, and ST65 sharing ack (8), ftsZ (13), glpK (14), gmk (6), and tpiA (10) alleles with ST233 and ST234 have been linked to mastitis in animals. Moreover, the broad host range of M. sciuri could facilitate the dispersal of antibiotic resistance genes. This study provides evidence of the importance of including migratory animals in monitoring the development and spread of antibiotic resistance
Work-family conflict: Evaluating the mediating role of personal intervening strategies
Balancing family and work roles places serious demands on working women most especially in African context where women also doubled as home keepers, and this represents a key factor in achieving sustainable productivity (SDG
8.2.3). The study was to expound work-family conflict experiences by married female workers in financial instit utions, and to determine whether personal interventions
play a beneficial role to improve productivity. The study adopted social survey with the use of self-administered questionnaire among 730 randomly selected married women bank employees. The study shows that 78.8% of female
bankers experience work-family conflict due to strain to keep the jobs and meet up with expected family roles. In the absence of effective workplace relief, several women resort to personal coping strategies this is statistically insignificant and having a negative relationship depicting it is ineffective. The study concludes that the individual or personal intervention-based approach at minimizing work-family conflict could not be adjudged as effective. Therefore, a systematic and robust organization-based approach may be necessary as panacea for work-family conflict within the sector considered and the country as a whole
Developmenrt of EST-SSR and genomic-SSR markers to assess genetic diversity in Jatropha Curcas L.
<p>Abstract</p> <p>Background</p> <p><it>Jatropha curcas L. </it>has attracted a great deal of attention worldwide, regarding its potential as a new biodiesel crop. However, the understanding of this crop remains very limited and little genomic research has been done. We used simple sequence repeat (SSR) markers that could be transferred from <it>Manihot esculenta </it>(cassava) to analyze the genetic relationships among 45 accessions of <it>J. curcas </it>from our germplasm collection.</p> <p>Results</p> <p>In total, 187 out of 419 expressed sequence tag (EST)-SSR and 54 out of 182 genomic (G)-SSR markers from cassava were polymorphic among the <it>J. curcas </it>accessions. The EST-SSR markers comprised 26.20% dinucleotide repeats, 57.75% trinucleotide repeats, 7.49% tetranucleotide repeats, and 8.56% pentanucleotide repeats, whereas the majority of the G-SSR markers were dinucleotide repeats (62.96%). The 187 EST-SSRs resided in genes that are involved mainly in biological and metabolic processes. Thirty-six EST-SSRs and 20 G-SSRs were chosen to analyze the genetic diversity among 45 <it>J. curcas </it>accessions. A total of 183 polymorphic alleles were detected. On the basis of the distribution of these polymorphic alleles, the 45 accessions were classified into six groups, in which the genotype showed a correlation with geographic origin. The estimated mean genetic diversity index was 0.5572, which suggests that our <it>J. curcas </it>germplasm collection has a high level of genetic diversity. This should facilitate subsequent studies on genetic mapping and molecular breeding.</p> <p>Conclusion</p> <p>We identified 241 novel EST-SSR and G-SSR markers in <it>J. curcas</it>, which should be useful for genetic mapping and quantitative trait loci analysis of important agronomic traits. By using these markers, we found that the intergroup gene diversity of <it>J. curcas </it>was greater than the intragroup diversity, and that the domestication of the species probably occurred partly in America and partly in Hainan, China.</p
