Literature review of clinical presentation, management and prophylaxis of vestibular migraine is presented in the paper. [ABSTRACT FROM AUTHOR]

This paper is intended to reveal possibilities to research of broken wire on the wire ropes using dynamic properties of tensed wire rope and research properties of broken wire in piece of wire rope when it is affixed on the wire rope in special test rig. During experimental test wire rope and broken wire on the tensed wire rope dynamic properties was estimated depending on excitation frequency, also including affixed weight on the tensed wire rope dynamic properties. Finally, results are given and conclusions are made. [ABSTRACT FROM AUTHOR]
