Food Rheology using Dynamic Mechanical Analysis; A short review
(Paul Kamweru, 2020-02)An ideal elastic material will deform finitely and recover its original shape and size upon the removal of the applied deforming load. On the other hand an ideal fluid will deform and continue to deform as long as the ... -
Forecasting Commodity Price Index of Food and Beverages in Kenya Using Seasonal Autoregressive Integrated Moving Average (SARIMA) Models
(Springer, 2021-12)Price stability is the primary monetary policy objective in any economy since it protects the interests of both consumers and producers. As a result, forecasting is a common practice and a vital aspect of monetary policymaking. ... -

Formation of trimetallic complexes containing redox-active nitrosyl molybdenum tris(3,5-dimethylpyrazolyl)-borato groups. Schiff base compounds containing two Mo and one Cu centre
(Elsevier, 1994)The reaction of [Mo(NO)Tp*Cl2] [Tp* = tris(3,5-dimethylpyrazolyl)borate] with copper(II) Schiff base complexes derived by condensation of two mole equivalents of 2,5-dihydroxybenzaldehyde with α,ω-diamines [1,2-C6H4(NH2)2, ... -
Gas-phase total oxidation of benzene, toluene, ethylbenzene, xylenes using manganese oxides and copper manganese oxide catalysts.
(American Chemical Society, 2012-05-17)Volatile organic compounds (VOCs) continue to be the major source of direct and indirect air pollution. Here, cryptomelane-type octahedral molecular sieve (OMS-2) manganese oxide, amorphous manganese oxide (AMO), and mixed ... -
Generating, Rectifying and Stepping Up the Voltage Output of Piezoelectric Plate
(International Journal of Research Publications, 2020)Energy is required in all sectors that either supports or improves human life. However, some of the methods of power generation e.g. the fossils fuels are non-renewable and have byproducts that harms the environment. For ... -
Genetic and phenotypic diversity of microsymbionts nodulating promiscuous soybeans from diferent agro-climatic conditions
(Springer Open, 2022)Background: Global food supply is highly dependent on feld crop production that is currently severely threatened by changing climate, poor soil quality, abiotic, and biotic stresses. For instance, one of the major challenges ... -
