Plasma sterilization of microorganisms
The sterilization efficiency of oxygen plasma was studied. Plasma was created in pure oxygen with an inductively coupled radiofrequency discharge. The discharge power was estimated to about 180 W. Plasma parameters were measured with a double Langmuir probe and a catalytic probe. Plasma parameters depended on pressure in the discharge …
Analysis of bacteria damages caused by treatment with oxygen plasma particles
The possible mechanisms for destruction of two types of bacteria with oxygen radicals were studied. Samples consisting of standard ATCC strains of Gram – positive bacteria Staphylococcus aureus and Gram – negative bacteria Escherichia coli were obtained. Bacteria were cultivated according to the standard procedures and fixed on substrates of …
Modular gene dynamics and network theory at mesoscopic scale
Complex dynamical systems are often modeled as networks, with nodes representing dynamical units which interact through the network’s links. Gene regulatory networks, responsible for the production of proteins inside a cell, are an example of system that can be described as a network of interacting genes. The behavior of a …
