“…Race cars vibrate. The sources of vibration include rotation of drivetrain components, wheel-and-brake assemblies, interactions between the tires and the road surface, flexing of aerodynamic surfaces, and harmonics of the chassis, engine, and other components [ 37 , 38 , 39 ]. The race car structure is stiff, and there is little to dampen the transmission of vibrations to the driver [ 40 , 41 , 42 ].…”

Redox homeostasis and redox-mediated signaling mechanisms are fundamental elements of human biology. Physiological levels of reactive oxygen species (ROS) and reactive nitrogen species (RNS) modulate a range of functional processes at the cellular, tissue, and systemic levels in healthy humans. Conversely, excess ROS or RNS activity can disrupt function, impairing the performance of daily activities. This article analyzes the impact of redox mechanisms on extreme task performance. Such activities (a) require complex motor skills, (b) are physically demanding, (c) are performed in an extreme environment, (d) require high-level executive function, and (e) pose an imminent risk of injury or death. The current analysis utilizes race car driving as a representative example. The physiological challenges of this extreme task include physical exertion, g loading, vibration, heat exposure, dehydration, noise, mental demands, and emotional factors. Each of these challenges stimulates ROS signaling, RNS signaling, or both, alters redox homeostasis, and exerts pro-oxidant effects at either the tissue or systemic levels. These redox mechanisms appear to promote physiological stress during race car driving and impair the performance of driver athletes.

Introduction. This article describes an algorithm developed by the authors for the operation of a crane anemometer that measures the gust rate and average wind speed and determines the predicted wind speed on the basis of it. The main part. The main influencing parameters and their measurement intervals are defined for the construction of the anemometer algorithm. The method of calculation of gust velocity and average wind velocity from the data of the pulse sensor of the helicopter anemometer is presented. The method of wind speed forecasting based on the construction of an extrapolation function is given.Results. An anemometer program algorithm with extended capabilities relative to existing analogues has been developed. The instrument not only captures the hazard at the moment, but also predicts its future development. On the basis of the analysis of wind dynamics studies, a table has been compiled of the levels of the determined parameters (gust rate, average speed and projected average wind speed) and the signals given to the operator of the crane. For each type of signal, the value of the removal delay is defined.Conclusions. ZAO KROS Engineering and Technical Centre has made a prototype anemometer using the principles described in this article. The device meets all requirements of the regulatory and technical documentation. Further work on the improvement of the algorithm of its work will make it possible to increase the safety of technological processes carried out with the use of elevated structures.
