Ibrahim Adepoju Babatunde
Open Access Library Journal (OALib Journal) , 2020, DOI: 10.4236/oalib.1105996
This paper titled Policy institutional approach to transport failure in Nigeria, Encapsulating the fundamental issue and challenges that initiated transport system failure in Nigeria, despite transport sectors having immense potentials to contribute to the growth and development of the national economy. This paper examines the challenges and failure of all forms of transport system in Nigeria with a view to digress from aged long theoretical and conceptual framework to a more practical approach, in order to reduce the existing transport problem. This has been done by looking at the institutional framework and policies from post independent till date. The author researched on the paper with dependence on primary data, secondary data, textbooks, reliable internet websites and operational case study since there is a scarcity of professional material in the subject area. At the end of the paper, the presenter proposed a number of recommendations among which is the involvement of trained transport professional intransportpolicies, training, and practice, cou- pled with frequent review and approval of transport policy papers to reflect social, economic and environmental challenges of the country. It is believed that this research will be useful for transport policy formulator, students, researchers and also stakeholders in transport practice.

Early season maize is harvested with high moisture content that makes it impossible to store. The sale of early season maize in green form is uneconomical to the farmer. Experience had shown that farmers could hardly make the cost of production from their sales. Also, grain losses are high when maize is harvested green. To minimize grain losses and thereby increase value and the profit margin of the farmer, a grain dryer is necessary for wet grains. Therefore, this paper presents the design and development of a batch in-bin maize grain dryer. Some properties of maize such as moisture content and bulk density were determined to get information required for design of the dryer. The dimension of drying chamber, amount of moisture to be removed in a batch, quantity of air required to effect drying, volume of air required to effect drying, blower capacity, quantity of heat required to effect drying and actual heat used to effect drying were all designed for. A maize dryer was developed with a batch size of100 kg of threshed wet maize. The dryer can be used in laboratory for experimental purpose as well as on the farm for commercial purposes. The dryer can be used to measure drying rates of maize at different initial moisture contents, drying air temperatures, drying air velocities and grain beds. The effects of different drying temperature, air velocity, loading and agitating speed on the quality of dried maize can be investigated with the dryer.

Leonardo Electronic Journal of Practices and Technologies , 2011,
Abstract: In this work, the effect of addition of Calcium Nitrate on selected properties of concrete containing Volcanic ash as partial replacement for ordinary Portland cement by weight was investigated .The study carried out used 10% volcanic ash as partial replacement and an admixture, Ca(NO3)2 Was added to improve the strength of the resulting concrete at 2%, 4%, 6% 8% and 10% respectively. The result of setting time showed a decrease in both initial and final setting time of the mixture as the Ca(NO3)2 Content was increased. The result of chemical analysis of volcanic ash showed an increase in calcium oxide (CaO) content when calcium Nitrate Ca(NO3)2 was added from 11.67% to 33.68%. Cubes were cast and cured in water for 7, 14, 21, and 28 days .The resulting Strength at 28 days hydration period shows a strength increase as the percentage of Ca(NO3)2 was increased to 10%.

Abstract: Objective. Increasing prevalence of asthma has been attributed to changes in lifestyle and environmental exposures. We conducted a case-control study to investigate the relationship between serum micronutrients and asthma in rural school children in Nigeria. Methods. We administered questionnaires to 1,562 children to identify children with asthma. Serum concentration levels of 12 micronutrients were determined in asthma cases ( ) and controls ( ). Allergy skin prick test and spirometry were also performed. Results. Plasma levels of the following micronutrients were significantly different between cases and controls: calcium ( versus ?mg/dL; ), manganese ( versus ?mg/L; ), selenium ( versus ?μg/L; ), and albumin ( versus ?g/dL; ). Plasma concentrations of iron and selenium were positively correlated with lung function, ( in each case) while manganese serum concentration was negatively correlated with asthma ( ; ). Conclusions. Children with asthma had reduced levels of plasma manganese, calcium, and albumin but raised level of selenium. The protective or risk effects of these micronutrients on asthma warrant further investigation. 1. Introduction In most developing countries, including Nigeria, asthma has become one of the most common chronic diseases among children. It is a major cause of emergency hospital visits and school absenteeism among children younger than 15?years of age in most developed countries [1, 2]. However, hospital visitations among children with asthma in Nigeria, especially in rural areas, remain very low due to limited access to healthcare services and increased focused efforts on diseases such as tuberculosis, measles, and malaria [3]. While asthma may be previously reported to be uncommon in most parts of sub-Saharan Africa [4, 5], recent studies have demonstrated a high prevalence of asthma and other respiratory diseases among school-aged children and adolescents in Nigeria [6–8]. Some population-based studies have attributed this increase to changes in lifestyles and nutrition, suggesting a likelihood of higher prevalence of asthma in countries where there is a shift from traditional to westernized lifestyles [9, 10]. Recent clinical observations and epidemiological studies have identified associations between nutritional elements (e.g., magnesium, calcium, copper, zinc, selenium, and vitamin D) and asthma prevalence [9, 11, 12]. It is thought that micronutrients influence the immune system and may play a major role in the development of asthma and in the progression of other allergic diseases [9, 13–15]. However, only few of

Abstract: Geochemical survey of residual soils was undertaken in Dagbala-Atte District of Igarra Schist Belt, southwestern Nigeria to explore for base and precious metals (Cu, Pb, Zn, Au and Ag). It involved sampling residual soil from 49 sites in a grid pattern; analyzing the soil samples for the base and precious metals and other commonly associated elements including As, Cd, Fe, Hg and Sb; subjecting the geochemical data generated to statistical analysis; and preparing the geochemical distribution map of the district for each element.? On the basis of the multivariate statistical analysis (correlation matrix and factor analysis) of the soil geochemical data, three mineralization types were inferred to be present in the district. The suspected types of mineralization consist of: 1) Cu-Pb-Zn-Ag mineralization with associated As, Hg, Sb and Fe; 2) Au-Cu mineralization with associated As; and 3) minor Hg-bearing Au-Pb mineralization. With the aid of the elemental geochemical distribution maps, the suspected mineralization was linked to rock types from which the sampled residual soils were apparently derived. Hence, the suspected Cu-Pb-Zn-Ag mineralization is linked to the quartz-biotite schist at the southwestern part of the district while the suspected Au-Cu mineralization is located on the silicified sheared rock at the northern and southern parts and the minor Hg-bearing Au-Pb mineralization within the granitic gneiss at the northeastern and eastern areas of the district. Based on the foregoing findings, it is recommended that lithogeochemical survey for the base and precious metals should be done in the area.

Journal of Food Technology , 2013, DOI: 10.3923/jftech.2010.99.101
Abstract: Seeds of locust bean (Parkia biglobosa) were boiled for 12 h and soaked for 8 h and re-boiled for 1 h with the addition of potash as a softening agent and subjected to fermentation for 48 h. The unfermented and fermented (dawadawa) beans were then analyzed for proximate compositions. The results of the chemical analyses indicate that fermentation resulted in protein and lipid enrichment and a reduction in total carbohydrate. It was concluded that processing locust bean into dawadawa increases the key nutritional constituent, protein. This explains why dawadawa is commonly included in stews and soups as a substitute to animal protein among the low income earners in less developed and developing countries.
Gender, Age and Locus of Control as Correlates of Remedial Learners’ Attitude towards English Language
T Adepoju
African Research Review , 2010,
Abstract: The study sought to explain remedial learners’ attitude towards English language using three variables: gender, age and locus of control. Three properly validated instruments were used to collect data on the relevant variables from 385 remedial English learners randomly selected from 5 remedial education centers in Ibadan, Nigeria. Data analysis involved the use of multiple regression to explain the relationship between learners’ attitude towards English and the 3 independent variables. The results showed that gender, age and locus of control, when acting together, predict attitude and at the individual level of contribution, only one variable– locus of control was significantly predictive of attitude towards English language. These findings have far-reaching implications for adult and non-formal education practitioners and other stakeholders interested in improving the lots of several learners out there, in English language.

Pakistan Journal of Social Sciences , 2012, DOI: 10.3923/pjssci.2010.81.84
Abstract: The study sought to determine, the extent to which some personal and environmental variables predict adult audience attitude towards broadcast news. Sample for the study was made up of 180 randomly selected respondents of both sexes but from heterogenous and diverse backgrounds from 6 local government areas in Ibadan city, Nigeria. Data were collected using Attitude Towards Broadcast News Scale with construct validity and internal reliability coefficient of 0.874 (Cronbach coefficient alpha). Data analysis involved the use of Multiple Regression Analysis. The findings showed that the seven personal and environmental variables in the study, when taken together were quite effective in predicting adult audience attitude broadcast news with Multiple R = 0.70 and R2 = 0.59. It further showed that only four of the variables viz marital status, type of employment, literacy level and age, exert significant influence on attitude towards broadcast news. The findings have important implications for broadcast media practice, communication and media art students, language, communication and media arts instructors, scholars and professionals, literacy planners, policy makers and the society at large.

Abstract: Energy drinks are non alcoholic, carbonated beverages claimed to give extra burst of energy for daily obligation. They contain some form of legal stimulants and vitamins which are meant to give consumers short term boost in energy and increase mental alertness. Energy drinks enjoy patronage especially among higher institution students in Nigeria, but little is known about the consumption pattern and possible health risks to consumers. This study was carried out to determine the contribution of four commonly consumed energy drinks to energy intake of University of Ibadan students and the associated health risk factors. A descriptive cross-sectional survey of energy drinks consumption was carried out using a four-stage systematic random sampling technique to select 307 students from six out of nine halls of residence for Undergraduates and the two Postgraduate halls. A validated semi-structured, self-administered questionnaire was used to collect information on socio-demographic characteristics, consumption pattern and frequency, and factors influencing consumption of energy drinks. Samples of the four most commonly consumed energy drinks by the students (Power Horse, Emerge, Red Bull and Matador brands) were purchased from different stores within and around the University of Ibadan campus. Composite samples of all the four energy drinks (with at least six months expiration date) were analysed for physico- chemical characteristics, gross energy, minerals and B-vitamins content in triplicate using standard methods of AOAC. Data were analysed using descriptive statistics and one way ANOVA, and level of significance set at p < 0.05. Respondents mean age was 23.1 ± 4.6 years, 79.2% were undergraduates and 51.1% were female. Majority (74.6%) of respondents had ever taken energy drinks prior to the study, 42.4% reported consuming at least one can in a week, and 52.1% consumed 1 can at a sitting. Reasons for consumption included to increase: energy (48.2%), mental alertness (18.6%) and athletic performance (9.5%). Reported side effects were: insomnia (14.0%), frequent urination (12.2%), dehydration (11.3%), anxiety (9.1%), heart palpitation (3.5%). Frequency of consumption was significantly associated with gender (p < 0.05). Titratable acidity, total solids and pH of energy drinks ranged between 7.57 ± 0.60 - 8.28 ± 0.08, 7.57 ± 0.60 - 11.42 ± 0.31, and 3.36 ± 0.08 - 3.81 ± 0.12 respectively. Glucose, sucrose, and gross energy content ranged between 7.77 ± 0.01 - 7.89 ± 0.01 g, 22.61 ± 0.07 - 23.74 ± 0.09 g, and 43.59 ± 0.38 - 48.89 ± 0.28 kcal/100g

African Research Review , 2011,
Abstract: This study assessed and investigated the academic performance of secondary school students in two principal subjects (English Language and Mathematics) at the Senior School Certificate Examinations (SSCE) in ten secondary schools typical of urban and rural locations in five randomised Local Government Areas of Oyo State, Nigeria between 2005 and 2007. The study employed a descriptive survey research design. An instrument titled: Students’ Academic Performance in English Language and Mathematics Questionnaire (SAPEMQ) was used to collect relevant data for the study. The ten secondary schools involved were selected based on simple randomsampling technique and the statistical tools employed to analyse the data collected were percentages, means scores and multiple regression (backward procedure). Four research questions and one null hypotheses were formulated to guide the study. The result among other things revealed that, there was a marked difference in the performance of students in urban and rural schools at the SSCE with impressive means scores obtained in urban schools (Urban = 69.8, 54.4 and 60.2 in 2005, 2006 and 2007 respectively;Rural = 36.4, 24.9 and 23.8 in 2005, 2006 and 2007 respectively). The implications of the findings for educational planning and policy in Nigeria were discussed.
