- This study researches into solid waste management in South-West Nigeria in relation to pollution control using a an North as a case study. The generation pattern storage, collection and transportation, and the final disposal of solid waste ocean government are all discussed. Data used for this study were collected by the use of structured questionnaires and oral interviews. Analysis of the data revealed that all the functional elements of solid waste management system in the local government and the city of lbadan in general as practiced by existing institution - Ibadan Solid Waste Management Authority, are engulfed with fundamental problems which apparently have been the reason why institutions are unsuccessful in the efficient management of solid waste and control of environmental pollution. The various problems are identified, analyzed and discussed, pragmatic means of solving the problems, such as the encouragement of waste recycling; the active provision 2 results 2

- "Road bumps play a crucial role in enforcing speed limits, thereby preventing overspeeding of vehicles. It significantly contributes to the overall road safety objective through the prevention of accidents that lead to deaths of pedestrians and damage of vehicles. Despite the importance of road bumps, very little research has been done to investigate into their design. While documentation exists on quantitative descriptions of road bumps, they offer little guidance to decision making. This work presents a unique approach to solving road bumps design problems. The results of our study reveal three important road bumps variables that influence the control of vehicle speeds. The key variables are bump height, bump width, and effective distance between two consecutive road bumps. Since vehicle speed control is the ultimate aim of this study the relationship between vehicle speed and other variables earlier mentioned is established. Vehicle speed is defined as the product of frequency at which a vehicle is moving over road bumps and the sum of effective distance between two consecutive road bumps. In the determination of bump height we assume a conical shaped curve for analysis as a matter of research strategy. Based on this, two stages of motion were analysed The first concerns the motion over the bump itself while the second relates to the motion between two consecutive road bumps. Fourier series was then used to formulate a holistic equation that combines these two stages. used trigonometric functions to model the behaviour of the first stage while with the second stage giving a functional value of zero since no changes in height are observed. We carried out vibration analysis to determine the effect of road bumps on a vehicular system. Arising from this a model component is referred to as an isolation factor. This offers guidance to the safe frequency at which vehicles could travel over road bumps. The work appears to contribute to knowledge in road bump research through the development of a novel approach to the control of vehicle speeds. Significant research progress could be made if engineering and academic communities at large appreciate our viewpoints. With this work it is apparent that varying of the assumptions made in terms of bump shape may produce high proliferation of beneficial research studies. Although this work may reveal a new way of investigation into road bump research, no claim is made for the work comprehensiveness. We expect experts to challenge some of our thoughts and ideas presented in this work " 1 results 1

- Background Little is known about how to scale up care for depression in settings where non-physician lay workers constitute the bulk of frontline providers. We aimed to compare a stepped-care intervention package for depression with usual care enhanced by use of the WHO Mental Health Gap Action Programme intervention guide (mhGAP-IG). Methods We did a cluster-randomised trial in primary care clinics in Ibadan, Nigeria. Eligible clinics were those with adequate staffing to provide various 24-h clinical services and with regular physician supervision. Clinics (clusters), anonymised and stratified by local government area, were randomly allocated (1:1) with a computer-generated random number sequence to one of two groups: an intervention group in which patients received a stepped-care intervention (eight sessions of individual problem-solving therapy, with an extra two to four sessions if needed) plus enhanced usual care, and a control group in which patients received enhanced usual care only. Patients from enrolled clinics could participate if they were aged 18 years or older, not pregnant, and had moderate to severe depression (scoring ≥11 on the nine-item patient health questionnaire [PHQ-9]). The primary outcome was the proportion of patients with remission of depression at 12 months (a score of ≤6 on the PHQ-9, with assessors masked to group allocation) in the intention-to-treat population. This trial is registered with the International Standard Randomised Controlled Trials Number registry (ISRCTN46754188) and is completed. Findings 35 of 97 clinics approached were eligible and agreed to participate, of which 18 were allocated to the intervention group and 17 to the control group. 1178 patients (631 [54%] in the intervention group and 547 [46%] in the control group) were recruited between Dec 2, 2013, and June 29, 2015, among whom 976 (83%) were female and baseline mean PHQ-9 score was 13·7 (SD 2·6). Of the 562 (89%) patients in the intervention group and 473 (86%) in the control group who completed 12-month follow-up, similar proportions in each group had remission of depression (425 [76%] in the intervention group vs 366 [77%] in the control group; adjusted odds ratio 1∙0 [95% CI 0·70–1·40]). At 12 months, 17 (3%) deaths, one (<1%) psychotic illness, and one (<1%) case of bipolar disorder in the intervention group, and 16 deaths (3%) and one (<1%) case of bipolar disorder in the control group were recorded. No adverse events were judged to be related to the study procedures. Interpretation For patients with moderate to severe depression receiving care from non-physician primary health-care workers in Nigeria, a stepped-care, problem-solving intervention combined with enhanced usual care is similarly effective to enhanced usual care alone. Enhancing usual care with mhGAP-IG might provide simple and affordable approach to scaling up depression care in sub-Saharan Africa. 1 results 1

- English Language is the medium of instruction in secondary schools in Nigeria and as a global language, it enables students to communicate effectively with the wider world. Reading comprehension is one of the important skills in English Language and learners‘ academic attainments depend largely on their level of competence in it. However, available data shows that students‘ persistent failure in it could be attributed to their lack of factual and contextual knowledge of the target skill, personal characteristics and methods adopted by the teachers. Based on this, it becomes imperative to examine variables that contribute to students‘ learning outcomes in English Reading Comprehension. Therefore, this study examined the correlates of psychological factors, classroom environment and teaching methods in students‘ learning outcomes. The study was a correlational research. Multistage sampling technique was adopted in selecting seven local government areas across the three senatorial zones in Ondo state. A teacher of English language from each of the 54 selected schools and a total of 2,055 students participated in the study. Six research questions were formulated and answered. Data were collected using six valid and reliable instruments: Reading Anxiety Scale (r=0.91), Reading Motivation Scale (r=0.94), Students‘ Attitude towards English Reading Comprehension Scale (r=0.88), English Reading Comprehension Classroom Environment Observational Checklist (π= 0.88), English Reading Comprehension Teaching Methods Observational Scale (π= 0.86) and English Reading Comprehension Achievement Test (r=0.84). Data were analysed using descriptive statistics and multiple regression. Students‘ attitude towards English Reading Comprehension was high as 87.1% of the respondents agreed that Reading Comprehension was an important aspect of the English Language. The combination of the independent variables showed that there was a positive relationship among psychological factors (reading anxiety and reading motivation), classroom environment and 12 teaching methods (mastery learning, advanced organiser, problem solving, demonstration, laboratory, discovery, lecture, concept mapping, discussion, mental imagery, cooperative and questioning), and students achievement scores (R=0.381), F(15,1959)=22.156, p<0.05). The composite contributions of the independent variables showed strong positive relationship among the 15 independent variables on students‘ attitude; (r= 0.916, 83.9%, .839, F(15,1959) = 684,74; p<0.05). Among the variables that contributed relatively to students‘ achievement in order of significant magnitude of beta weights were mastery learning (β=0.152, t=6.490, p<0.05), mental imagery (β=0.091, t=3.736, p<0.05), classroom environment (β=0.096, t=3.728, p<0.05), questioning (β=0.068, t=2.902, p<0.05) and lecture (β=0.063, t=2.645, p<0.05). Those that had relative and significant contributions towards students attitudes were motivation (β=0.759, t=75.763, p<0.05), discovery (β=0.102, t=16.439, p<0.05), discussion (β=0.079, t=7.616, p<0.05) and mastery learning (β=0.065, t=6.144, p<0.05). Psychological factors, classroom environment and teaching methods are very important to students learning outcomes. Reading motivation could be increased with the provision of appropriate instructional materials by education stakeholders. Teachers of English Language should adopt teaching methods that will maximize competence of the learners given the variations in their verbal ability and background knowledge 1 results 1

- Environmental pollution due to improperly managed wastewater has been a major challenge and of public health concern in Nigeria. Not many studies related to wastewater management have been carried out in Nigeria, hence the paucity of data on wastewater management in the country. The Wastewater Treatment Plants (WTP) in Nigeria's capital city, Abuja are presently performing below capacity due to several problems. The aim of this study was to evaluate the wastewater management system for Abuja and develop an engineering strategy to improve it. Six WTPs at Wuye lagoon, Gudu, Niger, Lungi, Mogadishu barracks and Sheraton were assessed in comparison with the existing wastewater Master Plan of Abuja. The sites were visited along with their sewer lines and manholes to assess their structural and environmental engineering adequacy. Influent and effluent samples were collected weekly from these plants at peak period in the morning hours (6.00 - 7.00am) in triplicates over six months period from October 2007 to March 2008. These samples were analyzed for quality parameters such as 5-Day Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), nitrate, nitrite, sulphate, chloride, phosphate, and microbial content. Data were further analysed using ANOVA at p= 0.05. Based on the evaluation, a suitable wastewater treatment plant was designed. These WTPs are mini activated sludge treatment plants with submersible mechanical aerators. Wuye lagoon has a capacity of 50,000 Population Equivalent (PE). Gudu, Lungi and Mogadishu barracks have 6000 PE each while Niger and Sheraton have 3000 PE each. Average reduction of BOD5 of 6±50.2%, 4±25.8%, 30±0.8%, 10.2±0.2%, 10.8±24.9% and 5±39.6% were observed for Wuye lagoon, Gudu, Mogadishu, Niger, Lungi and Sheraton respectively. For other evaluated parameters, average reduction in COD, nitrate, sulphate, chloride, phosphate and microbial quality were 7.8±12.4%, 13.1±4%, 13.5±65.4%, 21.5±89.8%, 10.1±8.4% and 48±87.9% respectively. Sludge treatments significantly affect the physico-chemical parameters. No regular aeration was carried out in the plants. In the satellite towns of Gwagwalada, Kuje, Kubwa and Nyanya, there were no sewer facilities, hence septic tanks and soak-away pits were constructed to handle the generated wastewater which is contrary to the provisions of Abuja Master Plan. Non-biodegradable substances such as nylon and plastics were observed in manholes. Discharge of evacuated septic sludge into sewer lines was the practice. A wastewater treatment plant combining both natural and electromechanical system was designed (Design flow of 2070 m3/d, BOD5 of 517Kg/day and Suspended Solids of 517.5kgSS/day). The treatment plant using water hyacinth yielded nutrient removal of about 70.0% when power is not available and enhanced treatment of up to 99.0% BOD removal when power is available. The designed wastewater treatment plant using appropriate engineering strategy was adequate and capable of solving the wastewater management problems of Abuja. The design would be useful in other major cities in Nigeria. 1 results 1

- Functional literacy is an essential objective of primary education in Nigeria which equips pupils not only with reading and writing skills, but also with numeracy, communication, problem solving and application skills in daily life activities. The inability of many Nigerian primary school pupils to read, write, compute, comprehend and communicate effectively in English Language has been attributed to factors which have direct links with the implementation of the school curriculum and supportive facilities. Further, studies have revealed that school factors have strong effects on pupils‟ acquisition of basic literacy and numeracy skills, but not much attention has been paid to their influence on functional literacy skills among primary school pupils in Nigeria. This study, therefore, investigated the relationship between school factors (curriculum implementation, teacher quality, school location, class size, school library) and pupils‟ functional literacy skills. The study was a survey research of ex-post facto type. Multi-stage sampling procedure was used to select 10 local government areas, 40 public schools (30 urban and 10 rural), 40 primary five teachers and 1106 pupils from the five educational zones in Ondo State. Five instruments used were: Observational Scale on Curriculum Implementation (r=0.81); Observational Scale on Teacher Quality (r=0.82); Functional Reading and Writing Skills Test (r=0.81); Functional Numeracy Skills Test (r=0.80) and School Library Inventory. Six research questions were raised and answered. Data were analysed using descriptive statistics, Pearson‟s product moment correlation and multiple regression. Curriculum implementation was poor (weighted average was 1.48 out of 4.00). Curriculum implementation (r= .22; p < .05), teacher quality (r= .27; p < .05), and school library (r= .08; p < .05) each had significant positive relationship with pupils‟ functional literacy skills. However, school location (r= -.23; p < .05) and class size (r= -.13; p < .05) each, had significant negative relationship with pupils‟ functional literacy skills. Pupils in urban schools performed better than pupils in rural schools. Also, pupils in small classes performed better than those in large classes. The five school factors (curriculum implementation, teacher quality, school location, class size and school library) jointly had significant positive relationship with pupils‟ functional literacy skills (R= .34; F(5, 1100) = 29.43; p< .05). They contributed 11.8% of the total variance to pupils‟ functional literacy skills. The order of relative contributions of the school factors to pupils‟ functional literacy skills was: school location (β= .19), teacher quality (β= .16), class size (β= .11), curriculum implementation (β= .05) and school library (β= .01). Of the five school factors, only three significantly predict pupils‟ functional literacy skills. These were teacher quality (B=.31; t=3.30; p< .05), school location (B= -8.50; t= -6.37; p< .05) and class size (B= -1.51; t= -3.85; p< .05). Teacher quality, school location and class size influenced pupils‟ functional literacy skills. Consequently, teachers need to sharpen their skills in curriculum implementation to enhance pupils‟ functional literacy skills. Qualified teachers, adequate learning materials, classrooms and well equipped libraries should also be provided for effective teaching. 1 results 1

- Information literacy recognizes the need for information to solve problems, develop ideas and locate appropraite information that would be used by individuals. The school library media centre has an important role of disseminating information to all students regardless of their physical abilities. This article examined the acquisition of information literacy skills by disabled students and the role of the school library media specialist in ensuring that they become information literate through the teaching of information skills that wpuld give them lifelong support in accessing information necessary for their daily living. The study also examined the objectives of information literacy and the advantages of information literacy skills. The article recommended, among others that school library media specialist should work pro-actively in partnership with special education teachers through curriculum planning and also to align the school library with educational goals as relating to information literacy skills of the disabled. Gender link is not a determinate of getting into managerial cadre in Librarianship in Nigeria. This article is of value to those interested in studying gender inequality. " 1 results 1
