Ngerebara, Gbosidom, L. Victor & Lawrence, O. Amadi Abstract: Abstract The present study investigates ultimate biodegradability potential of drilling fluids-oil base and water base, and oil spill dispersants - OSD/LT and OSD/Seacare employed in the upstream sector of the Nigerian petroleum industry in fresh water environment. Percentage ultimate biodegradability and petroleum product utilizing bacteria (PPUB-log10cfu/ml) were used as methods for the assessment of biodegradability potentials of the drilling fluids and oil spill dispersants. The results of the percentage (%) ultimate biodegradability of the drilling fluids and oil spill dispersants at day 20 showed the following trend: water base (55.5%) > oil base (54.8%)> OSD/Seacare (54.1%) >OSD/LT (41.1%). The results of petroleum products utilizing bacteria (PPUB-log10cfu/ml) at day 20 followed the trend: Water b base DF (4.89±0.65)>OSD/LT (4.71±0.05)> oil base DF (3.45±0.31)> OSD/Seacare (3.30±0.58). The PPUB-log10cfu/ml decreased from day 1 to 20 with drilling fluid water base contaminated fresh water sample having the highest cumulative count (4.89±065). The perturbation of biogeochemical cycles by these pollutants could have altered the process of decomposition, mineratization and nutrient regeneration. In conclusion, the study showed that drilling fluids were relatively more biodegradable than oil spill dispersants. ... more |

| 3 | Title: EFFECTS OF PROGRAMMED INSTRUCTIONAL PACKAGE ON SECONDARY SCHOOL STUDENTS’ ACHIEVEMENT IN ELECTROLYSIS Author: Iheanyi O. Igwe PhD. & Nneka Lucy Okoye Abstract: Abstract There is the prevalence of poor achievement in Chemistry commonly noticed in secondary schools and among Chemistry students. This has been attributed to the use of inappropriate teaching methods by Chemistry teachers. In order to empirically substantiate this assertion and to possibly proffer lasting solution, this study sought to determine the effects of Programmed Instructional Package on Students’ Achievement in Electrolysis. The study adopted a quasi-experimental design based on the pre-test post-test, non-equivalent control group approach. A total of 1,750 Chemistry SS II students from Port Harcourt Education Zone comprised the population for the study. The sample comprised 161 SS II Chemistry students. Four secondary schools were randomly selected out of twelve secondary schools. Two schools were assigned to the experimental group and the two to the control group. Intact classes were used in teaching. The experimental group students were taught Electrolysis using the Programmed Instructional Package while the control group students were taught using the Chalk and Talk Teaching Method. The instrument for data collection was the Electrolysis Achievement Test (EAT) which was face validated by three experts; two in Chemistry and one in Measurement and Evaluation. After item analysis, the reliability of Electrolysis Achievement Test (EAT) was determined using the Kuder-Richardson 20 and a reliability coefficient of 0.93 was obtained. Three research questions guided the study and three null hypotheses were tested for significant difference at 0.05 alpha level. Adjusted mean and standard deviation were used to answer the research questions while the hypotheses were tested using Analysis of Covariance (ANCOVA) at p > 0.05 level of significance. Results of the study showed that (i) mean achievement score of students in the Programmed Instructional Package group (the experimental group or treatment group) was higher than that of the students in the Chalk and Talk Teaching Method group (control group). (ii) Female students achieved higher mean score than the males. (iii). There was no interaction effect of teaching methods and gender on students’ achievement mean score. (iv) there was a significant difference in achievement mean score of students taught Electrolysis using Programmed Instructional Package and those taught using Chalk and Talk Teaching Method at 0.05 alpha level. (v). achievement mean scores for gender was not significant. (vi). There was no significant interaction effect of teaching methods and gender on students’ achievement mean score. Based on the results of the study, it was recommended that Programmed Instructional Package should be adopted by Chemistry teachers in teaching Electrolysis to secondary school students. Secondly, the method should be used to close the gap in achievement differences between male and female students. ... more |

| 4 | Title: ENVIRONMENTAL POLLUTION AND MATERNAL MORTALITY IN NIGERIA Author: Saturday, Odepeli And Nye, Oruwari PhD. Abstract: Abstract This study examines the consequences of environmental pollution on maternal mortality in Nigeria with emphasis on the proliferation of pollutants in most nooks and cranes of the country. Data for the study are generated from secondary sources of World Development Indicator and Central of Nigeria Statistical Bulletin of various issues. The data is analyzed using the Toda-Yamamoto estimation technique for the analysis. The study used maternal mortality rate as the dependent variable while carbon dioxide, nitrous oxide and particulate matter are used as the main explanatory variables for environmental pollution, whereas government expenditure on health is used as check or control variable. The finding reveals that carbon dioxide, nitrous oxide and particulate matter do not have causal effect on maternal mortality in Nigeria within the period of study. Implying that environmental pollution do not contribute to maternal deaths in Nigeria within the period of study. Although the impact of environmental pollution considering the status of the result is not the focal cause of maternal mortality in Nigeria in the period of study, the study recommends the following in order to achieve a better and healthier environment. Tree planting is one of the best means of mitigating the impact of environmental pollution because of its absorptive nature. On this premise, tree planting should be made a priority in the local, state and federal levels. Also, products that utilize solar energy, wind energy, hydro energy and other renewable product should be made tax free in order to encourage mass production. ... more |

PhD & Dibie Kashiari Esther, PhD Abstract: Abstract BACKGROUND: This study investigated the impact of occupational hazards on the productivity of artisans in Edo State. The study was guided by four dimensions of occupational risk which included physical, biological, chemical and psychological hazards. A cross-sectional survey project was conducted among artisans in Edo State. A questionnaire was developed to respond to the research hypotheses. A total of twelve hundred (1200) artisans were deliberately selected METHODS; Across the state. The questionnaire was based on the Likert scale. Content validity was used to determine the validity of the tool while Cronbach Apha was used to determine the reliability of the study which produced a coefficient of 0.88 (88%) for physical risk, 0, 82 (82%) for chemical hazard, 0.67 (67%) for biological hazard, 0.77 (77%) for psychological hazard and 0.78 (78%) for productivity. The frequency distribution and the percentage were used to analyze the demographic profile of the respondents. Correlation was used to verify the presence of multicollinearity and multiple regression was used to analyze the study hypotheses. All dimensions of occupational risk have a negative impact on the productivity of artisans, but only RESULTS; physical risk is insignificant. This means that occupational risk has a negative impact on productivity. There should be occupational safety and health awareness among artisans with the aim of promoting the health and well-being of artisans and artisans should receive occupational safety and health training in order to minimize the number of causes of occupational risk, thereby increasing their productivity. ... more |

| 7 | Title: INFORMATION TECHNOLOGY ADOPTION CHALLENGES AND SUSTAINABLE ADMINISTRATION OF SMES IN NIGERIA: A POST COVID-19 EXPERIENCE Author: Cletus I. Emeti PhD., Margret T. Ekeins PhD. & Tare L. Odo Abstract: Abstract The paper took a critical look into information technology adoption challenges and sustainable administration of SMEs in Nigeria with emphasis on the experience after Covid-19 pandemic. The Small and Medium Enterprises (SMEs) and ICT have been credited with enormous contributions to the growth of the developed economies of the world. The SMEs provide the cornerstone on which any country’s economic growth and stability rests. Small businesses have witnessed constant challenges because of their attitude, behaviour and the activities of numerous entities associated with ICT adoption. These challenges most times, produce ICT anxiety, reduce the SMEs managers’ sense of control resulting to continuous difficulty in the adoption of IT facilities. Technology Acceptance Model was used as the most appropriate framework for the study. Similarly, qualitative research approach and applied chronological method in the analysis of mainly secondary data were used. Some of the challenges identified in the work includes low-income, limited IT skilled workers, workers resistance to change, limited ICT infrastructure and expensive nature of ICT. It is recommended that Nigeria should strive to strongly position herself to meet up with the requirements of ICT infrastructure, with specific reference to the SMEs. Also, SMEs in Nigeria should as a matter of necessity, equip themselves adequately with all ICT facilities and not just basic office tools. We mean relevant ICT gadgets as internet facilities, video conferencing facilities, facsimile, e-mail, etc. ... more |

| 8 | Title: THE EFFECT OF CORRUPTION ON CURRICULUM IMPLEMENTATION IN NIGERIA Author: Tupele-Ebi Enai Oyadonghan PhD. & Tamunodienye Mba PhD. Abstract: Abstract Curriculum is the bed rock of education; it specifies the methods, instructional instruments and the pedagogy of transferring knowledge from the teacher to the learner. When a curriculum is poorly implemented, the educational system will fail, and its policies and objectives will not be achieved. The poor educational system of Nigeria, characterized by lack of instructional materials, academic manpower and adequate infrastructural facilities for learning informs the educational doom currently facing the nation. Many scholars have associated this to poor educational policies and implementation. However, this study takes a critical look at the effect of the national problem of corruption on the implementation of curriculum in Nigeria, considering it as the root cause of the decay in the educational system of the nation. Primary date was collected with a questionnaire and distributed to two institutions of higher learning in Bayelsa State. Using the statistical package of social sciences (SPSS), a regression and correlation coefficient analysis was conducted to test the hypotheses. The results indicated an increase on the rate of corruption will lead to a more than average corresponding reduction on curriculum implementation. It is therefore recommended that financial accountability should be strongly entrenched in our educational systems.... more |

Abstract: Abstract The effects of pH, light and temperature on acetylene reduction by the lichen (Peltigera aphthosa) was investigated. Intact thallus and excised cephalodia of Peltigera aphthosa were incubated at various ranges of pH, temperatures and light intensities, and a comparative nitrogen fixation by the intact thallus and excised cephalodia was used as the method for assessment. Both the intact thallus and cephalodia were incubated at temperature range of 10 ºC to 30ºC, pH range of 4 to 8, and light intensities as low as 220 lux to a maximum of 11000 lux for 48 hours. Optimum nitrogenize activity was obtained at pH 5 and 7, 4000 lux and 20ºC for intact lichen material. However, for exercised cephalodia, incubation in the light at various levels over a 48-hour period, the optimum nitrogenase activity was inhibited, showing fairly broad in the range of 5-7, peaking slightly at neutral pH and declining markedly at pH 4 and 8. The study showed that separating the cephalodia from the main thallus lowered nitrogenase activity of the lichen. Obviously, the main thallus affects the cephalodial activity and the cause might be due to: (1) an accumulation of inhibiting nitrogenous compounds in the nostoc cells on separation from the main sink (medulla), (2) some stimulating effect(s) on the activities of the cyanophyte excreted by any of the main thallus partners is or are lost on separation, and (3) the metabolic activity of the cephalodal fungus may be lowered in the absence of the major sources of photosynthate, indirectly affecting the cyanophyte. ... more |
