Evaluation of Homogeneity from Ore-bodied in Nigeria for Secondary Mineral Prospective

Samples from ore–bodied areas at different locations in Papalanto and Ifo in Ogun-State, South-West of Nigeria, where Ewekoro cement industry is situated, were analyzed so as to recover some secondary minerals of economic value. The following parameters were evaluated, conductivity, turbidity, colour, pH and other chemical parameters. Variations of Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), sulphate, nitrate, phosphate, chloride ion contents, and temperature were also studied. Mineral-forming heavy metals were in the ranges Fe: 89.0–1080 mg/l; Mg: 869–1120 mg/l; Pb: 23–80 mg/l; Zn: 180-480 mg/l. The concentration of nitrate is 20-35 mg/l; phosphate: 8-80mg/l; Dissolved Oxygen (DO): 30–45 mg/l; Total Dissolved Solids (TDS): 89-900 mg/l; pH: 6.1-8.5; Conductivity: 10-18μs/cm3 and temperature ranged between 25-27oC. Also in the tabulation are the results of the homogeneity of four geochemical explorations from other Nigerian ore-bodied environments for comparison. Correlations of some of the physical and chemical parameters have been established with the view of providing conditions for the formation of secondary minerals and the types of such minerals expected from the studied areas. The minerals may include the following groups of minerals: Adelite, Melilite, Cancrinite and Copriapite. The study apart from the present knowledge on ore-based baseline also present information on the pollution studies of the area under investigatio

Analyzing and Interpreting Research in Health Education

The research carried out in health education is holistic and all embracing. It may be qualitative, quantitative or mixed. While qualitative research is used when little or nothing is known about the subject, quantitative research is required when there are quantifiable variables to be measured. By implication, health education research is based on phenomenological, ethnographical and/or grounded theoretical approaches that are analyzable by comparison, or sometimes a cross sectional study, cohort study, case-control study, and randomized controlled trial, which are in turn analyzable by statistical values and tests of significance. While qualitative research is interpreted by inductive reasoning, quantitative research is by deductive interpretation. Health education Research may therefore be one of concept formation and development, concept modification and integration in a research based on grounded theory, culture characterization in ethnographical studies and data ranking and classification in phenomenological studies. It counts occurrences, establishes statistical links among variables, and generalizes findings to the population from which the sample was drawn. Acceptance or rejection of data is a common feature in the process of reconciling conflicting evidence. Consequently, the goal of research in health education is generation of theory, cultural taxonomy/themes, and application of findings in other settings/geographical locations.Keywords: Analyzing, Interpreting, Research, Health Educatio

ON THE EFFECTIVENESS OF THE LOCALLY FORMULATED CUTTING FLUID

A Locally made cutting fluid emulsion of l5% concentration was formulated. M:tchinniJility tcsls wca·c condudcd on medium carbon steel using a single point ·high-speed steel (I-ISS) cuHing tools to determine the effectiv~ness of the formulated cutting fluid. The cutting speeds of 24, 27, 30, 33, and 361\1/min were used. The· flanks wear land and nose wear of the tool wcr·c measured after each machining interval using mitutoyo toolmaiH·rs microscope with a magnification of 30. It was found that the tool wear charadrris(ics and tool life, using the locally formulated cutting fluid were in close ag:·£_~J1Cllt wiJJLJh~- PTE'!YL<?.!ILJ1'Drks.
