Two approaches: the Composite Index Approach and the Time Analysis Approach were used in calculating water poverty index in Ekiti State using a wide range of data generated from household surveys in ten local government areas out of the existing sixteen local government areas of Ekiti State. The hydrological and hydraulic parameters in the Local Government Areas in Ekiti State were considered as well. The result obtained shows that using the composite index approach with parameters such as water availability, accessibility to safe water, time taken to access water among others, the Water Poverty Index (WPI) of 20.8, 18.7, and 18.7 were obtained in Moba, Irepodun/Ifelodun and Ado Local Government areas respectively. This is higher than that of Ekiti East, Ise-Orun and Ikere Local Government areas with 10.2, 15.5 and 16.5 water poverty index in that order. This indicates that people in Moba, Irepodun/llfelodun and Ado Local Government areas experience little stress in accessing safe water when compared with people in Ekiti East, lse-Orun and Ikere. In Time Analysis Approach, water poverty index (WPI) of 0.17, 0.32 and 0.33 were obtained in Ido-Osi, bye and Irepodun/Ifelodun Local Government areas respectively while higher water poverty index of 0.60, 0.57, 0.50 and 0.48 were obtained in Ekiti East, Ekiti South West, Ise-Orun and Ikere Local Government areas respectively. This indicates that Ekiti East, Ekiti South West, Ise-Orun and Ikere Local Government areas are more water stressed in terms of accessibility to safe water xi, 71p. : ill. ; 30cm 2009-02-01T00:00:00Z http://196.220.128.81:8080/xmlui/handle/123456789/5916 FACTORS AFFECTING COMFORT LEVEL OF BUILDINGS IN LAGOS STATE OLOKO, GANIYU ADEKUNLE The problem of natural cooling of buildings in tropical climate has been considered in this research. Two locations Ebute Metta of Lagos Mainland and Ikorodu zones were chosen for the research where the ambient and room (indoor) temperatures of some selected buildings were taken. The research showed that natural cooling of buildings could be achieved by: • Building houses/rooms to face South or North. • Using asbestos sheets as roofing Material • Leaving spaces between buildings to allow for free airflow. etc. • Limiting the number of people using a room. Statistical methods were used in the analysis of the collected data which later showed that the both calculated and measured data are almost equal in every aspect. vii, 116p. : ill. ; 30cm 2004-10-01T00:00:00Z http://196.220.128.81:8080/xmlui/handle/123456789/5915 EVALUATION OF SOME PHYSICAL AND MECHANICAL PROPERTIES OF SELECTED WALLING MATERIALS HARUNA, Ibrahim Olusegun Current high cost of conventional walling materials, the desire for reasonable thermal comfort and problems involved in the analysis of heating and cooling systems call for the search for alternative walling materials. In this work, some physical and mechanical properties namely: compressive strength, moisture content and shrinkage were evaluated for selected mixes of sawdust concrete and Electric Arc Furnace (EAF) slag cement blocks. The samples were prepared by grinding, sieving and mixing with water to ensure cohesion and firmness. The blocks derived were fired in muffle furnace to 12000C and then allowed to dry in still air. Their properties were evaluated/measured, The values obtained were subjected to statistical analysis using the general linear model. Particular attention was given to the EAF slag-cement blocks where gradual replacement of cement by EAF slag of 10%, 15% and 25% were carried out. Control cubes used for comparison of compressive strength were made from cement-sand of 1:8 mix ratio. EAF slag cement blocks had higher cohesion, higher compressive strength, low moisture content and negligible level of shrinkage. This encourages building with less cement thus assisting in obtaining relatively low cost, durable and functional buildings. Building with blocks made by replacing cement with EAF slag to 25% level of reduced cost. xii, 62p. : ill. ; 30cm 2006-09-01T00:00:00Z http://196.220.128.81:8080/xmlui/handle/123456789/5914 EVALUATION OF COMPOSITE SAWDUST BRIQUETTE AS A HIGH GRADE FUEL FOR DOMESTIC COOKING KUTI, OLAWOLE ABIOLA Evaluation of Composite Sawdust Briquette as a high-grade fuel for domestic cooking is discussed in this write-up. Composite sawdust briquettes were produced by mixing sawdust and palm kernel shell of sizes 1.18mm, 2.00mm and 2.36mm in percentage ratios of 90: 10, 80:20, 70:30, 60:40 and 50:50 respectively. Starch was used as a binding agent. The whole mixtures were compressed at 6.89Mpa (1000 Psi.) using a manually operated hydraulic briquetting machine. Experimental tests like Calorific Value Test, Water Boiling Test and Controlled Cooking Test were carried out on the samples having sun dried them properly for some days. The 70:30 composite briquettes with palm kernel shell size of 1.18mm were considered best under the Calorific Value and Water Boiling Tests. These were used to cook food items like yam, rice and beans under the Controlled Cooking Test. Its performance was compared to that of kerosene fuel under the same test. The data obtained at the end of the experiments were analysed statistically. A cost analysis was carried out to compare the cost effectiveness of using the briquettes with kerosene fuel. xi, 155p. : ill. ; 30cm 2003-08-01T00:00:00Z
