Determination of damage threshold of cassava green mite (Acari: Tetranychidae) on different cassava varieties for pest management
(2014)Density threshold has been least considered in efforts to control cassava green mite (CGM) of the Mononychellus species. Nine cassava varieties of varied cyanogenic contents were evaluated for CGM density threshold. Mite ... -
A Simplified Formalism for Computing Growth Rates for Perturbations in Standard Cosmology
(2015)We present a simplified formalism for computing growth rates for perturbations within standard cosmology. We show that converting the perturbation evolution equations into ordinary differen1ia1 equations in terms of ... -
