A Plasma Reactor for Experimental Investigation of Sterilization Processes: Preliminary Results on Escherichia Coli
نویسندگان
چکیده
Plasma process is a promising physical method for sterilization. Due to the lack of suitable plasma diagnostics, installed in reactors, general knowledge happens about gas-phase chemical composition and influence operating parameters. The same case gas generated from different gases, candidates sterilization purposes. aim this work understand role agents acting process, evaluate effectiveness precursor gases validate reactor dedicated. A reactor, equipped with an extended set diagnostics dedicated understanding process. microbiological investigation carried out efficiency steps on cultures Escherichia coli, using both hydrogen peroxide argon. effects colonies Coli are assessed terms species present chamber, acquiring spectra resulting exposure Petri dish With regard action Peroxide Argon plasma, CFUs counted each significant point cycle survival curves provided. Differences emerge between mechanisms time. show more effective sterilizing plasma. validation necessary by appropriate statistic considering resistant microorganisms. Reactor will be used use non-corrosive non-irritating gas, such as argon, purpose implies simplification plant equipment. It would possible remove components vaporization concentration peroxide, eliminate management boxes containing discarded managed date hazardous wastes reduce significantly risk health professionals.

متن کاملPreliminary results on dynamic analysis of a new test rig for wheel-rail contact studies
A new reduced–scale test rig is developed owing to significantly contribute to the applicability of the laboratory tests on rolling contact fatigue (RCF) in wheel-rail material. This paper introduces the dynamic analysis of the test rig, in order to assess the vibration behaviour of the system with respect to contact phenomenon. Finite element modelling (FEM) is used to simulate the mecha...
متن کاملPreliminary results on multi-body dynamic simulation of a new test rig for wheel-rail contact
The ability to perform rolling contact fatigue (RCF) experiments in wheel–rail material is provided by a new small–scale test rig, manifesting the actual dynamic behaviour of the railway system. In this paper, a multi-body dynamics (MBD) model is proposed, simulating the vibration behaviour of the prescribed rig. The new testing facility is modelled using a three-dimensional model of the vehicl...
