This study aimed at evaluating Matisaa gray rock (MGR) for clinker production. MGR is naturally abundant in Matisaa, a rural area in Mwingi West District, Kitui county, Kenya. It is locally used as a gabion filler and other concrete structures with desirable physico-mechanical properties. This research employed a controlled experimental design to determine the clinker qualification of MGR. This was based on particle size analysis and raw meal moduli. The standard sieve tests and a Blaine meter were used in the determination of particle size while the raw meal moduli were determined from the respective cement oxides in MGR, which were determined using wavelength dispersive X-ray fluorescence (WDXRF) spectrometer. It was observed that 69.65% of the particle size composition of MGR was less than 90 . Out of this composition, 71.60% of the particle sizes were less than 45 , contributing to a specific surface area of 292.5 . The hydraulic modulus (2.05 – 2.61) and lime saturation factor (0.87 – 0.98) are quite desirable though the silica and alumina ratios are higher than the standard range due to the low proportions of and content. The sulfatisation modulus is also undesirable due to the high content of . Thus, without beneficiation, Matisaa gray rock would lead to the production of low-quality clinker. However, the general parametric comparison of Matisaa gray rock with Konza shows that it has the potential for utilization as a clinker raw material.

The aim of the study was to compare the Ink, Lipstick and the Improvise Digital Methods by quantitatively and quantitatively analyzing some dermatologlyphic features of the digit and palm. Twenty one Biomedical Technology students were recruited for the study. The prints of the digits and palms of all participants were taken using the ink, lipstick and Improvise digital methods. In addition all participants were also trained to take the prints using all the methods and analyzed dermatoglyphic features. Dermaltoglyphic parameters evaluated were digit patterns, total finger ridge count (TFRC) and ATD angles. In addition direct one-on-one interview method to measure participants’ response to each of the methods was done. Chi-square test and paired t-test was used to analyze the results. There was no significant difference (P> .05) in the qualitative results for digit patterns obtained by the Improvise digital method with either of the other two methods. But qualitative evaluation of ATD angle and TFRC showed a statistical difference (P = 0.00 and P = 0.01). The Improvise digital method was rated 94.74% on participants’ preference scale, 91.22% on ease of method and 94.74%.on convenience. All the methods have their comparative advantages but the Improvise digital method was most preferred by participants.

The assumption that intelligence and wait-to-hip ratio are inversely correlated has been a subject of debate. The aim of the study is to assess the relationship between waist-top-hip ratio and intelligence quotient. A total of one hundred and fifty Nigerian women between the ages of 18 to 28 years volunteered for the study. A modified method of Stanford Binet test for intelligent quotient was administered together with the measurement of the waist circumference (WC) and hip circumference (HC) to determine the waist-to-hip ratio (WHR). In addition to assessing the relationship of WHR and IQ of the whole volunteers, the volunteers were further grouped into four categories based on WHR to evaluate how WHR relate to IQ in each group. The data obtained were analyzed using Pearson’s correlation test and test of correlation value at 0.05 level of significance. The result of the present study shows that the average age, WC, HC, WHR, IQ and correlation value (r2 ) of the volunteers were 22.49 years, 72.17 cm, 96.51 cm, 0.75, 53.35, 0.0009 respectively. The Pearson correlation values were poor and insignificant (P= .05) for all classes of WHR versus IQ. The study shows the correlation between WHR and IQ is poor and not significant and therefore does not support the assumption that WHR is inversely correlated to IQ.
