Purpose.The purpose of this work is to determine the energy losses in the shock absorber of the freight car whose wheel-set moves in the derailed state on the track panel depending on the axle load and structural parameters of spring suspension.Methodology.On the basis of spring suspension construction analysis and operating principle of the fricti
The relative linear order of most genes on bacterial chromosomes is not conserved over evolutionary timescales.One explanation is that selection is weak, allowing recombination to randomize gene order by genetic drift.However, most chromosomal rearrangements are deleterious to fitness.In contrast, we propose the hypothesis that rearrangements in ge
Advances in microfabrication technologies and biomaterials have enabled a growing class of electronic devices that can stimulate and record bioelectronic signals.Many of these devices have been developed for humans or vertebrate animals, Travel Mug Lid where miniaturization allows for implantation within the body.There are, however, another class o
Harmonizing biodiversity assessments under the Marine Strategy Framework Directive (MSFD) at the pan-European level is a crucial task for the Regional Sea Conventions and EU Member States in the coming years, particularly for fish assessment in Descriptor 1 (biodiversity).Precondition for coherent fish assessments is the establishment of a regional
