  • Survival of honey bee (Apis mellifera) pupae after trypan blue staining of wounds caused by Varroa destructor mites or artificial perforation
    Apidologie, 2005
    Co-Authors: Matthias Herrmann, Ghazwan Kanbar, Wolf Engels
    Abstract:

    The recently described technique of vital staining with trypan blue to visualise pupal wounds of honey bees, originating from punctures made by Varroa destructor mites, was applied to artificial perforations performed with a fine needle. The stained pupae were subsequently reared in vitro until eclosion of the adult bees. Their mortality was recorded daily. The survival of the treated pupae was only moderately affected by the staining procedure. No obvious toxic effects caused by the compound trypan blue were observed. The process of wound healing was normal. Pupae with previously trypan blue stained integumental wounds can therefore be used for long lasting experiments. This is of particular interest for future studies on the assumed Vector Function of Varroa mites in the transfer of bacterial and viral pathogens in honey bee diseases.

  • lyapunov Vector Function method in the motion stabilisation problem for nonholonomic mobile robot
    International Journal of Systems Science, 2017
    Co-Authors: Aleksandr Andreev, Olga Peregudova
    Abstract:

    In this paper we propose a sampled-data control law in the stabilisation problem of nonstationary motion of nonholonomic mobile robot. We assume that the robot moves on a horizontal surface without slipping. The dynamical model of a mobile robot is considered. The robot has one front free wheel and two rear wheels which are controlled by two independent electric motors. We assume that the controls are piecewise constant signals. Controller design relies on the backstepping procedure with the use of Lyapunov Vector-Function method. Theoretical considerations are verified by numerical simulation.
