(Elsevier, 2013)The stability of parthenolide, the active ingredient in feverfew and a potential anti-inflammatory bioactive in beverages was evaluated at different pHs (2.9, 3.7, 4.6 and 6.0) during heat processing at 40–100°C. The ... -
The effect of purple tea extract activity on selected metabolic syndrome parameters in mice
(Meru University of Science and Technology, 2022-06)Metabolic syndrome (MetS) is a cluster of metabolic abnormalities. Prevalence of MetS is documented at 50% and 87.5% in Africa and Kenya respectively. It is managed by combining lifestyle modification and pharmacotherapy. ... -
Effect of Selected Metal Ions on the Mycelial Growth of Sclerotinia Sclerotiorum Isolated From Soybean Field in Rongai, Kenya
(International Journal of Chemistry and Materials Research, 2014)White mold caused by Sclerotinia sclerotiorum attacks a wide host range of broad-leafed plants which includes soybeans. The effect of twelve metal ions (Hg+2, Co+3, Ag+1, La+3, Cd+2, Cr+3, Cu+2, Zn+2, Mo+5, Sr+2, Sn+4 and ... -
Effect of Sulphate and Chloride Ingress on Selected Cements Mortar Prisms Immersed in Seawater and Leather Industry Effluent
(Hindawi, 2019)Cement structures are major capital investments globally. However, exposure of cement-based materials to aggressive media such as chloride- and sulphate-laden environments such as coastal areas affects their performance. ... -
Effects of Biocementation on some Properties of Cement-Based Materials Incorporating Bacillus Species Bacteria
(Taylor & Francis, 2019)There is a growing need in the construction industry to improve transfer and durability aspects of Portland pozzolana cement. Ureolytic bacteria have recently emerged as potential micro-organisms well known for precipitation ... -
Effects of Grafting Azacrown Ether on Thermal and Swelling Properties of Chitosan Films
(Multidisciplinary Digital Publishing Institute, 2017-11-17)The thermal and swelling properties of a series of azacrown ether-crosslinked chitosans prepared with varying molar amounts of N, N-diallyl-7, 13-diaza-1, 7, 10, 16-tetraoxa-dibenzo-18-crown-6 (molar equivalents ranging ... -
Effects of outliers on Estimation of Finite Population Totals
(International Journals of Multidisciplinary Research Academy, 2013)In this paper, attempt to study effects of outliers on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate of finite ... -
Effects of Sulfuric Acid Attack on Hydrated Calcined Clay Limestone Cement Mortars
(Taylor & Francis, 2020)The paper presents experimental findings on the performance of Limestone Calcined Clay Cement (LC3) in acidic media. LC3 was made by inter-grinding a blend of 50 % clinker with ground 30 % Fired Rejected Clay Bricks (FRCB), ... -
Effects of Temperature Dependent Viscosity and Viscous Dissipation on Fluid Flow Past a Moving Flat Plate
(International Journal of Innovative Science, Engineering & Technology (IJISET), 2016-12)In this study, the effects of temperature dependent viscosity and viscous dissipation on fluid flow over a moving flat isothermal plate have been investigated.
