In this paper, after analysing deformations of loading ball-bearing it is able to investigate vibrations of rotor-bearing system as the system with non-linear and periodically varying stiffness.The modelling of the systems is depent on properties of the shaft (rigid or flexible) and on measurement techniques for system vibrations (by eddy current p
The Quedius mutilatus group, a very poorly known presumably monophyletic complex of wingless, possibly hypogean species confined Support to the Tien-Shan Mountains, is characterized as such for the first time.Newly available material clarified the identity of Q.mutilatus Eppelsheim, 1888 and Q.kalabi Smetana, 1995, each hitherto known from a handfu
BackgroundMany ruminant diseases of viral aetiology can be effectively prevented using appropriate vaccination measures.For diseases such as Rift Valley fever (RVF) the long inter-epizootic periods make routine vaccination programs unfeasible.Coupling RVF prophylaxis with seasonal vaccination programmes by means of multivalent vaccine platforms wou
