Experience with adoption of flaw detectors in which ferromagnetic transducers are used for testing the solebar of freight car trucks in the railway system is outlined.
In the establishment of the dynamic model, for simplicity, one fourth of the freight car without lateral motions, namely a wheelset and the equivalent one fourth freight car body above it, is considered.
The possibility of a prognostic estimation of the body's functional state based on comparative analysis of biological age measured by physical work ability parameters in truck drivers was considered.
For the managers that thought their industry would become less important, the most noted reason was their trackage would not safely transport the newer very heavy bulk commodity freight cars.
In the active phase of the disease, hepatomegaly is seen together with the "wheel in wheel" phenomenon, the "wagon wheel" appearance and/or the "bull's eye" lesion.
The participation of intercellular extruded "wagon-wheel" bodies, MVB and atypical keratinosomes on an irregular baso-apical diffusion-barrier in the epidermis of cases with viral acanthomas has been discussed.
