In this article, the behaviour of tumour growth and its interaction with immune system have been studied using a mathematical model in form partial differential equations. However, development tumours how they interact make up an extremely complex little-understood system. A new has proposed to gain insight into role response microenvironment when no treatment is applied. The resulting set equa...

Abstract We propose a model for tropic interaction among the infochemical-producing phytoplankton and non-info chemical-producing microzooplankton. Volatile information-conveying chemicals (infochemicals) released by play an important role in food webs of marine ecosystems. Microzooplankton is ecologically grazer coexistence large number species. Here, we discuss how information transferred dim...
