Laser Shock Wave

In order to reveal the quantitative control of the residual stress on the surface of metal materials, the relevant theoretical and experimental studies were carried out to investigate the dynamic response of metal thin plates and the formation mechanism of residual stress induced by laser shock wave. In this paper, the latest research trends on the surface residual stress of laser shock processing technology were elaborated. The main progress of laser shock wave propagation mechanism and dynamic response, laser shock, and surface residual stress were discussed. It is pointed out that the multi-scale characterization of laser and material, surface residual stress and microstructure change is a new hotspot in laser shock strengthening technology.

Experimental studies were conducted on the basis of the Research Center for Biosafety and Environmental Control of Resources of the Agroindustrial Complex of the Dnipro SAEU, poultry farms of different directions of productivity of Donetsk-Prydniprovsky region of Ukraine in the period from 2016 to 2019. The purpose of the work is to determine the nature of pathomorphological changes and the status of systemic immunity in chickens with respiratory mycoplasmosis at poultry farms with various production. To determine the immunodeficiency and immunopathological conditions of a productive poultry with respiratory mycoplasmosis, a comprehensive immunological study was performed. Significant fluctuations in the absolute and relative values of leukograms and immunograms have been established, indicating a significant immunological alteration in chickens with respiratory mycoplasmosis. The most significant changes in the status of systemic immunity are found in chickens with respiratory mycoplasmosis at poultry farms with meat production, which are subject to more longer and more intense influence of human activity.
