In this paper we have considered a nonlinear and nonautonomous stage-structured HIV/AIDS
epidemic model with an imperfect HIV vaccine, varying total population size and
distributed time delay to become infectious due to intracellular delay between initial
infection of a cell by HIV and the release of new virions. Here, we have established some
sufficient conditions on the permanence and extinction of the disease by using inequality
analytical technique....
Nowadays there has been a growing consciousness among the tea industry to reduce
the use of the chemical pesticides for pest control. Predators are beneficial insects that feed on
harmful insects and mites, which incur considerable loss of production of tea. In this paper we
have considered a tritrophic model consisting of tea plant, pest and predator to analyze different
field observations. The effect of discrete time-delay on the tritrophic model is studied critically.
The dynamical behaviours...
