Hopf-Bifurcation Analysis of Pneumococcal Pneumonia with Time Delays
(Hindawi, 2019)In this paper, a mathematical model of pneumococcal pneumonia with time delays is proposed. The stability theory of delay differential equations is used to analyze the model. The results show that the disease-free equilibrium ... -
Analysis of Head Loss in Pipe System Components
(Mathematical Theory and Modeling, 2014)The problem under investigation is to determine the flow-field variables that is the total head which is the sum total of Elevation head, velocity head and pressure head instantaneous distributions as a function of distance ... -
Cross-Diffusion Effect on Mixed Convective Fluid Flow through Horizontal Annulus
(Mathematical Theory and Modeling, 2014)The unsteady mixed convective fluid flow through an annulus filled with a fluid-saturated porous medium is numerically investigated in this study in the presence of Cross-Diffusion effect and constant Heat Source. The flow ... -
Rhizons improved estimation of nutrient losses because of seepage in aquaculture ponds
(Journal of Earth Science & Climatic Change, 2017)The effects of climate change have highly challenged the productivity of the agricultural sector. The increasing temperatures and erratic rains, as well as diseases and pests have significantly reduced crop yields in the ... -
A review of aquaculture production and health management practices of farmed fish in Kenya
(International Journal of Veterinary Science and Medicine, 2018)Warm water aquaculture is widely practiced in Kenya and is dominated by the culture of Nile tilapia (Oreochromis niloticus) (75% of total production) followed by African catfish (Clarias gariepinus) at 18%. Aquaculture ... -

(International Journal of Scientific Research and Innovative Technology, 2017)In this paper, we mainly investigate the action of 𝑃𝐺𝐿 2,𝑞 on the cosets some of its subgroups namely; 𝐶𝑞−1,𝐶𝑞+1and 𝑃 𝑞. Corresponding to each action the disjoint cycle structures and cycle index formulas is ... -
A Study of Solutions to Euler Equations for a One Dimensional Unsteady Flow
(American Journal of Comp utational and App lied M athematics, 2013)In this paper we deal with the Euler equations for Isothermal gas. In analyzing the equations we obtain two real and distinct eigenvalues which enables us to determine the wave structure of the possible solutions to the ... -
Exploring the trophic structure in organically fertilized and feed-driven tilapia culture environments using multivariate analyses
(AquacultureResearch, 2006)Reports of similar yields in manure and feed-driven tilapia culture environments raise questions on food utilization in these environments. The possibility that similar production rates are because of utilization of di¡erent ... -
Ideotyping integrated aquaculture systems to balance soil nutrients
(Journal of Agriculture and Rural Development in the Tropics and Subtropics, 2011)Due to growingland scarcityand lack of nutrientinputs, Africanfarmersswitched fromshiftingcultivationto continuous croppingand extendedcrop area by bringing fragile lands such as river banks and hill slopes into production. ... -
