HOUSING QUALITY IN SUBURBAN AREAS (An Empirical Study of Oba-Ile, Nigeria)
OLOTUAH OLOTUAH,Abiodun Olukayode
Dimensi : Journal of Architecture and Built Environment , 2006,
Abstract: This paper discusses the housing quality in a city suburb, Oba-lle, which is a few kilometers from Akure, the capital city of Ondo State Nigeria. It reports finding from a research on housing studies in the study area. A linear model was developed through multiple regression analysis for the prediction of housing quality of the buildings therein. Three independent variables were found to be predictors of the dependent or criterion variable; these were Use of Toilet, Age of Buildings, and Frequency of Collection of Refuse. The regression coefficients of the predictor variables described the values by which the dependent variable (Housing quality) would change as a result of a unit change in any of the predictor variables. The model is thus pivotal in determining strategies for the improvement of housing quality in the study area.

O.F. Olotuah
Journal of Biological Sciences , 2006,
Abstract: Morphological and Anatomical analyses were carried out on eight bast fibre plants from two families; Malvaceae and Fabaceae in Akungba-Akoko. In the anatomical study, the fibres were extracted and a total of fifty cells were measured for each species. Certain fibre properties, the cell lumen, diameter and cell wall thickness were determined from which the Runkel ratio, slenderness ratio and flexibility ratio were obtained to consider the suitability of the plants in pulp and paper making. The studies on fibre properties showed that the fibre lengths ranged between 2.20 mm for Hibiscus sabdariffa and 3.92 mm for Sida acuta with variations within the measured lengths of a species. The best fibre distributions were observed in Hibiscus cannabinus with 78% and Urena lobata 80%, having lengths of more than 2.5 mm and a Runkel ratio of less than one.

International Journal of Biology , 2011, DOI: 10.5539/ijb.v4n1p96
Abstract: The powders and oils extracts of Anacardium occidentale (L.) seeds and Allium sativum (L.) bulbs were tested as contact insecticides against the cowpea bruchid, Callosobruchus maculatus (Fab.) in cowpea seeds. The powders were incorporated at rates 1, 2.5 and 5/20g of cowpea seeds and acetone extracts of the plants were also applied at 0.5, 1 and 1.5ml per 20g of cowpea seeds to assess contact mortality of adult insect, oviposition, adult emergence and damage assessment. The results obtained showed that at 72 hours; 1, 2.5 and 5/20g of cowpea seeds evoked 63.3, 80 and 100% adult mortality of the cowpea bruchid while the corresponding results for A. sativum were 60.7, 73.3 and 100% mortality respectively. All concentration of acetone extracts that were used evoked 100% mortality of C. maculatus after 72 hours of post treatment. Complete protection of seeds and complete inhibition of adult emergence in both powders and extracts of A. occidentale and A. sativum were achieved. The results obtained from this research revealed that powders and extracts of A. occidentale seeds and A. sativum bulbs were effective in controlling cowpea bruchid, C. maculatus in stored cowpea seeds.

Journal of Building Construction and Planning Research (JBCPR) , 2018, DOI: 10.4236/jbcpr.2018.62006
Abstract: The challenges facing public schools are multifaceted and include: teachers dissatisfaction, non-commitment of educators, chronic absenteeism by educators, low morale, poor work ethics by educators, late coming of both educators and learners, overcrowding in classes, lack of technical resources and many more. A cursory investigation of public secondary school buildings in Ado-Odo/Ota L.G.A shows its deplorable conditions of structural, aesthetical and decorative disrepair. Therefore the paper focused on examining users “perception of the present deplorable physical condition and neglect of public secondary school. The study engaged the use of quantitative method of analysis, employing the use of questionnaire administered randomly and distributed face-to-face to targeted despondences”. The result of findings revealed performance/productivity of building users depends largely on working and learning condition of building. The outcomes of the research would help policy makers, facilities maintenance experts and professionals alike to device a policy for regular maintenance of public building in other to enhance performance and increase productivity amongst users.

Journal of Applied Sciences and Environmental Management , 2010,
Abstract: The effect of storage on the efficacy of powders from Eugenia aromatica (Baill.) of different ages in the control of Callosobruchus maculatus (Fabricius), a major pest of stored cowpea seeds, were investigated in the laboratory. Powders stored for periods of < 1 month, 24, 36 and 48 months with particle size of 300 μm were tested. Contact toxicity was tested for the differently aged powders at 0.4 g of material per 20 g of seed in separate plastic Petri plates. In fumigant toxicity tests 20 g of infested cowpea seeds was suspended in a piece of muslin cloth, over 0.4 g of powder in a container. In the contact toxicity tests, all the differently aged powders killed C. maculatus adult within 48 hours. The differently aged powders significantly (P < 0.05) reduced oviposition by the introduced C. maculatus adults and adults did not emerge from eggs laid. In the fumigant toxicity test, first use of the differently aged powders prevented emergence of adult C. maculatus from fumigated eggs. In a consecutive reuse of powders, adults emerged from fumigated eggs but the numbers were significantly (P < 0.05) fewer than in the control. In conclusion, the shelf-life of E. aromatica powder as a bruchicide is at least four years.
Comparative Protection of Cowpea, Vigna unguiculata (L.) Walpers Against Field Insect Pests Using Cashew Nut Shell Liquid and Cypermethrin (Cymbush)

Pakistan Journal of Nutrition , 2010,
Abstract: The efficacy of ethanolic extract of Cashew Nut Shell Liquid (CNSL) in protecting Cowpea, Vigna unguiculata L. against field insect pests was ascertained through two field trials at two different planting seasons by comparing with a suitable insecticide, Cymbush 10 EC containing 100 g Cypermethrin per litre of water under natural infestation at Akungba-Akoko, Nigeria. The liquid which is viscous and contains Phenolic compounds was first standardized in the screen house using concentrations of 0.01, 0.1, 0.25, 0.5 and 1.0% to determine a marginal position of high protective capability and non-toxicity to the leaves. About 1.0% proved most effective and it was subsequently transferred to the field for comparison with Cymbush. CNSL was evaluated through the assessment of Insect Pest Number and Percentage Flower Infestation. From these, results were obtained on pod characteristics, yield and yield components, which showed that the 1.0% formulation of CNSL selected was as effective as Cymbush showing a comparatively higher protective ability.

Ige, O. E.,Olotuah, O.F,Akerele, V.
Modern Applied Science , 2011, DOI: 10.5539/mas.v5n4p74
Abstract: Studies on the floral biology and pollination ecology of three varieties of cowpea (Vigna unguiculata L. Walp) were carried out. The varieties studied were Var. Oloyin, Var. Sokoto, and Var. Drum. Cowpea is a self pollinated crop which is encouraged by the arrangements of the floral parts. However, Insects visiting cowpea flowers have been implicated in the movement of pollen from one cowpea plant to another. Flower opening of cowpea begins between 6:00am and 6:30am and closes between 11:30am and 12:00pm. Pollen analysis showed similarities in the pollen morphology of the cowpea varieties. Moreover Var. Drum produced the highest number of pollen grains per flower in terms of pollen productivity.

Abstract: Fumigant toxicity of crushed fresh bulbs of Allium sativum L. and A. cepa L. to the Callosobruchus maculatus (Fabricius), a major pest of stored cowpea (Vigna unguiculata (L.) Walp.) seeds was assessed under laboratory conditions in Akure, Nigeria. In the tests, 20 g of infested cowpea seeds were suspended in a piece of muslin cloth, over an amount of crushed bulb in a container with a tightly fitted lid. Adult emergence was completely prevented from freshly laid eggs of C. maculatus on cowpea seeds that was fumigated with 6.0 g or more of crushed bulbs of A. sativum. Such fumigated seeds were not holed at all. Other amounts of A. sativum tested (1.0, 2.0, 3.0, 4.0 and 5.0 g) significantly reduced C. maculatus adult emergence from fumigated eggs and seed holing in comparison with the control. Crushed A. sativum was ineffective in preventing adult emergence from fumigated C. maculatus larvae in seeds. The fumigant effect of crushed A. cepa did not kill all C. maculatus eggs. An amount of 7.0 g significantly reduced C. maculatus adult emergence from fumigated eggs and seed holing in comparison with the control. There is good prospect in using crushed bulbs of A. sativum> as fumigant in C. maculatus control in stored cowpea seeds. Se evaluó la toxicidad fumigante de bulbos frescos trozados de Allium sativum L. y A. cepa L. sobre Callosobruchus maculatus (Fabricius), una importante plaga de semilla almacenada de caupí Vigna unguiculata (L.) Walp. bajo condiciones de laboratorio en Akure, Nigeria. En las pruebas, 20 g de semillas infestadas se suspendieron en un trozo de tela sobre cierta cantidad de bulbos trozados en un contenedor con una tapa ajustada. Se previno completamente la emergencia de adultos desde huevos recién puestos de C. maculatus en semillas de caupí que se fumigaron con 6,0 g o más de bulbos de A. sativum. Estas semillas fumigadas no estaban ahuecadas. Otras cantidades de A. sativum probadas (1.0, 2.0, 3.0, 4.0 y 5.0 g) redujeron significativamente la emergencia de adultos de C. maculatus desde huevos fumigados y el perforamiento de la semilla en comparación con el control. A. sativum trozado fue inefectivo en la prevención de emergencia de adultos desde larvas fumigadas de C. maculatus en semillas. El efecto fumigante A. cepa trozada no mató los huevos de C. maculatus. Una cantidad de 7,0 g redujo significativamente la emergencia de C. maculatus adultos desde huevos fumigados y el perforamiento de semilla en comparación con el control. Los bulbos trozados de A. sativum se presentan como una buena alternativa como fumigante en el control d
