Memory, verbal onslaught and persuasive eloquence in Armah's Two Thousand Seasons and The Healers

Abstract: Language dissects thought. In language fortified with calculated verbal vituperation and persuasive eloquence, Ayi Kwei Armah takes his audience down memory lane—a retrospect (in the characteristic manner of the Sankofa model) into the original identity of the African. Sankofa dwells on the idyllic past which serves as a model for a restructured future. One hears the evocative voice of Anoa’s prophecy of two thousand seasons, wandering along other ways and finding paths of living way. The way is glaringly replete with verbal bullets with which Armah dwells on the Blackman’s indulgence. This gives rise to the flagrant losing of “the way” to the “predators” and “destroyers” in Two Thousand Seasons. In his advocacy for a restoration to the forgotten way, Armah’s verbal onslaught provokes sharp awakening that propels the people to a positive action to recover the lost way into “understanding the mind beyond despair to healing work”. In The Healers therefore, Armah’s in-depth philosophies led by the master healer, Damfo and the trainee healer, Densu provide keys to the restoration of black people and racial renewal. The focus of this study is Armah’s eloquent intellectual expressions: evocative poetic lamentation, prophecy, symbolism, and studded imagery of brutality, servitude and restoration. The work concludes by demonstrating Armah’s achievements with the deployment of linguistic weapons. Has he succeeded in making his reader / audience see clearly the Blackman’s annals of misdemeanor and the consequences? How realistic is his redemptive posture into Ebibirman; the liberated community of black people? This is the crux of this paper intertwined with Sankofa. Keywords: Ayi Kwei Armah, cultural activism, memory, post-colonialism.

Undergraduate-Fresher’s Behavior on a Choice of Course and Classroom Engagement in Universities in Rivers State: Lecturers’ View

Abstract: This study investigated the lecturers’ view on undergraduate fresher’s behavior on a choice of course and classroom engagement in the universities. Two research questions and one hypothesis guided the study. A correlational survey design was adopted in this study. The population of this study comprised one federal and two state universities in Rivers State having 5,025 lecturers from whom information was generated. A sample of 400 lecturers was drawn using a proportionate stratified random sampling technique representing 8% of the population. The instruments used for data collection were questionnaires titled "Undergraduate Fresher’s Behavior on Choice of Course Questionnaire (UFBCCQ) and Undergraduate Fresher’s Behavior on Classroom Engagement Questionnaire (UFBCEQ)”. The instruments were validated, and the reliabilities of the instruments were established using the test-retest method. In analyzing the data, the mean scores, standard deviation, and linear regression analysis were used to answer the research questions. Pearson’s Product Moment Correlation Coefficient was used to test the hypothesis of relationship at 0.05 alpha level. The results revealed among others that, undergraduates’ fresher’s behaviour on a choice of course determined their engagement in classroom activities. The findings indicated a significant relationship between undergraduates’ fresher’s behavior on a choice of course and classroom engagement in universities in Rivers State. Based on the findings, the study recommends proper sanitization of students, and a robust relationship between fresher’s students and lecturers.

Assessment of faecal pollution in nta-wogba creek in port harcourt, nigeria

Abstract: The research is on bacteriological analyses of water samples in NTA-Wogba Creek, Port Harcourt, Rivers State,Nigeria. Water samples were collected from Nta-Wogba creek at four different stations and analyzed for heterotrophic bacterial, and faecal coliform counts. Bacteria were isolated and identified using standard microbiology and chemical techniques. High heterotrophic bacterial counts (3.3 x 105- 9.9 x 105cful/ml), total coliform counts (1.7 x 103- 2.4 x103cfu/100ml) and faecal coliform counts (2.2 x 103- 5.4 103cfu/100ml) were observed in all sampling stations. Four bacterial sp were isolated: Klebsiella spp, Staphylococcus aureu, Escherichia coli and Serratia spp. The presence of bacterial agents in the creek has posed a serious threat to the health and wellbeing of users of the creek. It is recommended that adequate waste disposal facilities should be provided to inhabitants of the affected areas to prevent indiscriminate dumping of wastes into the creek. The Environmental Protection Agency should ensure that industries treat their wastes adequately before disposal into the creek. Artisans around the creek should not defecate into the creek, and the public generally should be educated on the health risks of indiscriminate disposal of waste and issues associated with faecal pollution. There should be health education on simple techniques to treat water at home such as boiling, chlorination, filtering and solar disinfection that could save a huge number of human lives.

Investigation into the Effect of Velocity Distribution on Dry Season Hydrocarbon Degradation in Pond System

Abstract: Investigation into the hydrocarbon degradation was examined by considering the effect of velocity distribution on substrate concentration and biomass built up as well as the physiochemical parameter of the pond system. The research work contains experimental and theoretical data. The model developed was simulated using the experimental data obtained from the field of investigation. The result obtained shown negative and positive velocity indicating that the negative velocity influences the inflow velocity distribution of the substrate as well as the physiochemical parameter concentration. The actual velocity operational on the pond system was evaluated by considering the different in positive (inflow) velocity from the negative (backflow) velocity. The research demonstrates the effect of velocity distribution on the substrate concentration, biomass build up, physiochemical parameters as well as evaluation of the theoretical maximum specific rated of microbial growth μTmax = 45.45 × 10−4 day−1, equilibrium constant for the microbial growth KTm = 0.0125, whereas the experimental values are given as μEmax = 10.0 × 10−5 (day)−1 and KEm = 200. It is seen that velocity distribution in pond system influence the effectiveness of bio-remediation of hydrocarbon.
