Control Strategy of the Brake Dynamics for Railway Vehicles Equipped with Anti-Slip-Device [PDF]
, 2006 From the point of view of railway vehicle braking processes it is an important requirement to maintain the roll-ing-motion-state of the wheels, i.e. the macro-sliding-free rolling contact between the vehicle wheels and the rail-head, since in the course ...

Wildlife Letters, EarlyView.Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.
