Gender, age and religion as determinants of eating habit of youth in ikenne local government of Ogun state, Nigeria.
The study examined the influence of Age, Gender and Religion on eating habit of youth. It made use of simple random technique in selecting 400 youths within Ikenne local government of Ogun State, Nigeria. The age range of the respondents was between 15 years and 40 years with the mean age of 25.2 and standard deviation of 3.291. The ex-post facto research design was employed. A 20 item questions by Snell &Johnson (1997) named psychology of eating questionnaire (PEQ) was adopted with four subscales and used in generating data for the study. Data analysis involved the use of analysis of variance, and independent t-test. The results indicated that the three variables age, gender and religion taken together accounted for 30.2% of the variance in eating habit pattern and were found to the significant with {F3.397} = 5.214 . On the basis of this finding, it is then suggested that: Eating habit is affected by gender and age, nutritionist, social workers and those concerned with health should create more awareness on the poor eating habit as regards to healthy living.
Key words: Gender, Age, Religion, and eating habi
Development of Zeolite Y from Arobieye Mined Kaolin
Zeolite Y was synthesized from Arobieye mined kaolin
in Ota, Ogun state Nigeria through metakaolinization and
zeolitization. The thermal activation of kaolin was achieved
through the process of metakaolinization while zeolitization
involved alkaline attack of thermally activated amorphous kaolin
(metakaolin) and its transformation into Zeolite Y crystal.
Silica/Alumina molar ratio of 5.84 of dealuminated metakaolin
was synthesized under hydrothermal treatment with aqeous
NaOH at atmospheric pressure after 7 days aging at room
temperature, and hydrothermally crystallized at 100oC for 24
hours. Zeolite NaY with Si/Al molar ratio of 3.46 was achieved
and then modified to its hydrogen form by ion exchange with
NH4Cl. The molar ratio of Zeolite Y in hydrogen form is 3.22.
The sample was characterized by Scanning Electron Microscope
(SEM) which gives Zeolite Y Structure
Development of alum from kaolin deposit using response surface methodology
A novel approach of for the formation of Hydrated Sodium Aluminium Sulpahte (Alum) from metakaolin was employed in this study. This process was used to form alum from metakaolin. It majorly involves captivating the self generated energy as a result of acid solvating in metakaolin-water solution to supply the mixing and activation energies requirement of the process without external heat source. The study gives a regression equation for the formation of Alum at a given volume of acid per gram metakaolin, temperature of reaction and desired conversion level

The thermal activation of kaolin was achieved through the process of metakaolinization at 850 oC for 6 hours in a furnace and dealumination with H2SO4 in order to achieve a desire silica/alumina molar ratio between 3 and 8. Zeolitization involved alkaline attack of dealuminated metakaolin and its consequent transformation into Zeolite Y crystal. Silica/Alumina molar ratio of 5.84 of metakaolin was synthesized under hydrothermal treatment with aqueous NaOH at atmospheric pressure. It was then aged for 7 days at room temperature and crystallized at 100 oC for 24 hours; Zeolite NaY of molar ratio of 3.46 was achieved and then modified to its hydrogen form by ion exchange with NH4Cl. The molar ratio of Zeolite Y in hydrogen form is 3.22. The samples were characterized with X-ray Fluorescence (XRF), X-Ray Diffraction (XRD), and Scanning Electron Microscope (SEM). The result showed that zeolite Y was synthesized from Arobieye mined kaolin with a molar ratio of 6SiO2 : Al2O3 : 9Na2O : 24H2O by ageing at room temperature for 24 hours and crystallized at 100 oC for 24 hours
Comparative Quality And Performance Analysis Of Manual And Motorised Traditional Portable Rice Threshers
Traditional motorized and manual portable threshers are the two types of threshers common to average farmer in the African continent and about 70% food production is in the hands of these categories of farmers. This paper compares the suitability of these types of threshers for traditional African farmers. The production rates (quantity threshed) and quality (seed loss and mechanical damage) were analyzed for both manual and motorized rice threshers using actual research data. The observed advantages and disadvantages based on production rate, quality, cost and farm sizes are outlined as a guide to farmers. The result of this analysis is also employed to improve the performance of motorized rice thresher. Key words: rice, threshers, farm machineries, portabilit
Experimentation And Modeling Of Infective Treatment And Recovery Of HIV Patients (A Case Study Of Kwara State)
The outbreak and spread of diseases have been studied for many years. The ability to make predictions about diseases could enable scientists to evaluate inoculation/vaccination or isolation plans and may have a significant effect on the mortality rate of a particular epidemic. Therefore this research experimentation and modeling of infective treatment and recovery of HIV patients (a case study of kwara state) will studynbspnbsp the rate at which people contact the HIV, investigate how many people a person can infect at a particular point in time. , develop model for male and female with HIV, develop estimating functions for such a model and determine the control measures and sensitivities to change in parameter. Regression analysis, Chi ndash square and SIR model were use to analyse the data. Result of the analysis using regression analysis give the fitted model Y= 12.302 + 0.00009X and Y= 13.077 + 0.00007X for male and Female respectively. The result shows that the fitted model is adequate and the rate at which people contact HIV is increasing. Also chi - square analysis revealed thatnbsp contacts ofnbsp HIV is not depend on gender and that there are differences in respondents health when taking drugs recommended by health workers. Further analysis using SIR model shows that there will likely be epidemic on HIV and that 29% of the male that have HIVnbsp must be treated to avoid epidemicsnbsp 9% of the female that have HIV must be treated to avoid epidemics. And we recommend that Health Planner should administer enough drugsnbspnbsp to HIV patient on regular basis and Health Planner should educate people more on HIV and the preventive measure should be thought

Plantain Value Chain Mapping in Southwestern Nigeria
Understanding relationships, opportunities and bottlenecks in a commodity value chain is crucial to the determination of the contribution of a commodity to economic development. The objective of the study was to Map Plantain Value Chain in order to identify the key players, their roles, value added along the chain as well as constraints. Personal Interview and Focus group discussions were used to collect primary data from the actors along the chain. Data were analyzed using descriptive statistics and Value added analysis. The study identified conventional and peculiar actors such as Input suppliers, Producers, Farm-Gate Assemblers, Market-Arena Assemblers, Insitu Wholesalers, Transit Wholesalers, Processors, Retailers and Consumers. The study revealed tremendous dominance of the Midstream sector in the commodity value chain and that Value addition, volume of trade and geographical coverage indices were highest at the midstream sector. The result revealed also that Plantains were traded mostly in unprocessed form and there was low level of export of the commodity. Producers sold most of their product (55%) at the farm gate. Horizontal flow of the commodity was prominent among the actors. Value added at processing level was estimated at ?111/kg of processed product. The cross cutting constraints among the actors were inadequate credit accessibility, high transportation cost, inadequate market access and inadequate storage facilities amongst others. The study recommends intervention in the area of linking actors in the value chain to prospective markets for them to benefit from the various activities. Keywords:Plantain, Value Chain Map, Value Chain Actors, Value Added, Southwestern Nigeria
Health Risks Associated with Consumption of Vegetables Grown using Domestic Wastewater in Minna, Niger State, Nigeria
Most vegetables consumed in the cities of developing countries are grown using wastewater discharged through township drainage network. This paper, therefore, investigates the risk involved in the consumption of such vegetables. The human daily intake rate (DIR) and Health Risk Index (HRI) of heavy metals were calculated using established formulae and the values of DIR ranged from 0.10 mg/kg/day to 0.71 mg/kg/day in wastewater plots in dry season for adults and 0.10 mg/kg/day to 0.14 mg/kg/day for children. Health risk index (HRI) values ranges from 0.40 mg/kg/day to 0.75 mg/kg/day in wastewater plots for adults in dry season and 0.20 mg/kg/day to 0.95 mg/kg/day for children. In wet season wastewater plots, the HRI ranges from 0.40 mg/kg/day to 0.95 mg/kg/day for children. The values of Hazard index (HI) ranged between 1.00 mg/kg/day and 1.21 mg/kg/day for all the seasons. Statistical analysis showed that there is a significant difference between the wet and dry season values for all the parameters assessed. Finally, uptake of heavy metals from the soil by all the vegetable crops under investigation was established. Therefore proper monitoring needs to be carried out to regulate consumption of vegetables produced from the experimental sites as continuous application of the industrial wastewater may lead to further accumulation of these heavy metals
Growth Pattern of Pseudomonas aeruginosa in different wastewater media
Restaurant wastewater are a major cause of environmental pollution with the indiscriminate release of the effluent to the environment resulting in blocking of drainages and eutrophication thereby causing serious threat to aquatic life. The growth pattern of a dietary rich oily wastewater degrading bacteria strain, Pseudomonas aeruginosa in different wastewater media composed to mimic the possible constituents of restaurant wastewater was investigated in this study. There was noticeable microbial growth in the synthetic and domestic wastewaters after 48h while the detergent wastewater and heated oil-detergent wastewater did not support the strain's growth. The decrease in the fat content with a corresponding increase in the ash content after 120h was due to the test strain's metabolic activity, which is slightly higher in domestic wastewater than the heated oil-detergent solution. Also, the potassium (K+), Mg2+, Fe2+ and Ca2+ contents increased within the same period in both media except in the domestic wastewater where the Ca2+ content reduced. Protease enzyme activity (46.440mM/min) was considerably higher in the domestic wastewater than lipase (3.322mM/min) and amylase activity (14.244mM/min) after 72 hours of incubation. The pristine genetic properties of Pseudomonas aeruginosa altered when cultured in various wastewaters probably due to variation in the composition of the substrates
