Effect Of Inhibitors

In this paper we have studied the effect of inhibitors on row-intercropping system by considering a two component species competition model proposed by Lotka (1920). We have verified our results by our experimental data. It has been observed that the inhibitors play an important role to shape the dynamical behaviour of the system.

The concepts of Stoeckli as well as those of Wojsz and Rozwadowski have been adopted for describing adsorption from two-component non-electrolyte liquid mixtures at solid adsorbents taking into account structural heterogeneity of the adsorbent. Some new global adsorption equations have been obtained and verified on the basis of experimental data.

The pseudogapped metallic state (PS) in high-T c superconductors (HTS) has distinctive characteristics in comparison with the metallic state in tranditional solid state physics. Through careful analyses of experimental data and theoretical calculations, we have correlated the pseudogap in the density of states with the two-component characteristics in the HTS. We propose seven points as a model description for PS.

Competitive Species

Limiting resource is a angular stone of the interactions between species in ecosystems such as competition, prey-predators and food chain systems. In this paper, we propose a planar system as an extension of Lotka-Voterra competition model. This describes? two competitive species for a single resource? which are affected by intra and inter-specific interference. We give its complete analysis for the existence and local stability of all equlibria and some conditions of global stability. The model exhibits a rich set of behaviors with a multiplicity of coexistence equilibria, bi-stability, tri-stability and occurrence of global stability of the exclusion of one species and the coexistence? equilibrium. The asymptotic behavior and the number of coexistence equilibria are shown by a saddle-node bifurcation of the level of resource under conditions on competitive effects relatively to associated growth rate per unit of resource.Moreover, we determine the competition outcome in the situations of Balanced and Unbalanced intra-inter species competition effects. Finally, we illustrate results by numerical simulations.
