Seven batches of concretes were cast at water to cement ratio of 0.5 and 5% fixed Metakaolin with 0, 5, 10, 15 and 20% Ground Scoria replaced cement. The resulting concrete then was tested for Slump. The Concrete cubes were cast and cured for 3, 7, 14, 28 and 60days before Water absorption and Compressive strength test were carried out. at all replacement levels of Metakaolin/Scoria content, Workability, Water absorption, Density and Compressive strength decreased when compared with the control concrete. However, Water absorption, Density and Compressive strength slightly increased with increase in curing age. The models developed were quite accurate as the percentages of error were in a good agreement and can explain the variability in Metakaolin/Ground Scoria concrete. Numerical method of optimisation was applied to d...

The study was anchored on four objectives to find out the rate of the spread of fake news among Nigerians on both social and conventional media; to examine the perception of media audience on fake news and abuse of freedom of expression; to find out the effect of fake news on Nigeria's democracy; to determine measures that can be adopted in combating fake news The study selected purposive sampling and surveyed 60 social media user from Borno and Yobe (i.e, 30 from each of the two states) and administered questionnaire. The study found that majority of the respondents contributes in the information sharing system of media cycle. The study found that despite the awareness of fake news among the respondents, there is limited alertness with regard to sensitivity of verifying information before sharing. The study also found that politics and crisis suffer more fake news than any other nature. The study found that fake news is still crucial because there are rounds of perceptions that influence its nature and thus its spread. We also found that the respondents have negative perception about the extent to which fake news can affect democracy and democratic system of governance. The study recommends that awareness should be created so as to enlighten people who use the social media to avoid spreading unverified information and that other social media platform should copy from Twitter in restricting number of text user can post and identification of a verified account.

The research was aimed to study the prevalence of Staphylococcus aureus among children diagnosed with acute diarrhea in Kura General Hospital Kano, Nigeria. Fecal specimens were collected in clean, dry and leak proof sterile bottle from 58 child patients (ranges from 1-5 years) admitted to Kura General Hospital and diagnosed with acute diarrhea from period of March to August 2017. The isolates were isolated and identified using Gram staining, Biochemical test (Catalase, Coagulase and DNase test), Mannitol fermentation and haemolysis test. The result showed that 34 samples out of 58 were positive for S. aureus. Higher incidence was found among males (20 subjects which accounted for 59%) than female with total of 14 subjects accounted for 41%. Highest frequency of diarrhea infection is found among subject with age between 1-2 years and more male (53%) were infected than female (47%). Statistical analysis of the result showed that there is no considerable statistical difference on prevalence of S. aureus among sex group and age categories of the subject at p<0.05. It is recommended that proper environmental sanitation, good personal hygiene and complete immunization against diarrhea disease are recommended.

The study involves batch type experiments to investigate the effects of initial concentration, adsorbent dose, agitation speed, contact time, temperature and pH of solution on adsorption process and the evaluation of optimum conditions. The adsorption process has fit pseudo-second order kinetic models. Langmuir and Freundlich adsorption isotherm models were applied to analyse adsorption data, and both were found to be applicable to this adsorption process. Thermodynamic parameters, e.g., ΔG • , ΔS • and ΔH • of the ongoing adsorption process have also been calculated and found the sorption process as endothermic. Finally, it can be seen that activated carbon obtained from palm fronds was found to be more effective for the removal of Cd (II) than activated carbon, under the same experimental conditions.

This is despite the existence of simple, effective treatment – zinc plus ORS. A comparative cross- sectional design was used to collect information from 302 caregivers. Data was analysed using SPSS version 20. Utilization of zinc plus ORS by caregivers was found to be good (73.5%) in both settings; up to 120 (78.9%) of the caregivers in the urban community compared to over two-thirds 102 (68.0%) of those in the rural community had used zinc plus ORS. This difference was statistically significant between urban and rural caregivers (P=0.01). Caregivers having poor knowledge of zinc plus ORS were 98% less likely to use zinc plus ORS (P=0.00, AOR=0.02, 95% CI=0.00-0.12), caregivers whose children had non severe diarrhoea are 80% less likely to use zinc plus ORS (P=0.00, AOR=0.20, ...

It was orchestrated on three specific objectives; to find out the perception of the students regarding the introduction of e-exam; to examine the perception of the students regarding e-exam as means of assessment; to examine the negative and positive perception of the students regarding the appropriateness of facilities, timing and format of question. The study employed the propositions of Technology Acceptance Model (TAM) to explain students' knowledge, acceptance and perception. The research used quantitative research method and survey methodology, using Questionnaire as instruments for data collection. The study purposely selected 200 students and found that majority of the students believe e-examination is better than the pen-paper examination. Majority of the students perceive electronic examination as an easy process. The study also found that the electronic examination is not suitable for every course to majority of the students. Majority of the respondents are against the format of the questions being asked via electronic examination. The study concluded that the introduction of eexamination in University of Maiduguri was a success despite having few challenges. The students perceived the new system as better means of assessment than pen-paper, even though they expressed dissatisfaction with the format of questions, examination timing and its suitability for some courses. It was recommended that the University of Maiduguri need to review the implementation of the new examination system in order to examine its suitability to all courses. Technical failures and limitation should be checked to improve effectiveness of the conduct of the examinations.
