Production of Pure Hydrogen Peroxide Solutions in Water Activated by the Plasma of Electrodeless Microwave Discharge and Their Application to Control Plant Growth

A method for the production of pure solutions of hydrogen peroxide during water activation by the plasma of electrodeless microwave discharge has been developed. It is shown that activated water has a pronounced effect on agricultural plants, being a non-toxic and chemically pure regulator of biological activity. In particular, the treatment of seeds of agricultural plants with activated water solutions can improve their drought resistance.

     

Stochastic systems with memory and jumps

Stochastic systems with memory naturally appear in life science, economy, and finance. We take the modelling point of view of stochastic functional delay equations and we study these structures when the driving noises admit jumps. Our results concern existence and uniqueness of strong solutions, estimates for the moments and the fundamental tools of calculus, such as the Itô formula. We study the robustness of the solution to the change of noises. Specifically, we consider the noises with infinite activity jumps versus an adequately corrected Gaussian noise. The study is presented in two different frameworks: we work with random variables in infinite dimensions, where the values are considered either in an appropriate $L^p$-type space or in the space of càdlàg paths. The choice of the value space is crucial from the modelling point of view, as the different settings allow for the treatment of different models of memory or delay. Our techniques involve tools of infinite dimensional calculus and the stochastic calculus via regularisation.
