[Vertebrogenic and atherosclerotic mechanisms of vertebral basilar insufficiency: comparative ultrasonic characteristics].

Using a complex of ultrasonic methods, vertebral basilar system hemodynamics has been evaluated in normal state and in case of vertebral basilar insufficiency (VBI). The differential diagnostic criteria of atherosclerotic and vertebrogenic types of VBI development have been obtained that enables to individualize the therapeutic approaches.

[Computer model of a human body].

The theory of combined designing was made use of to construct a global computer-based model of human organism--it provides for determining different treatment schemes, it can be used to define negative side-effects of treatment and it helps the doctor in choosing a more rational therapy technique for an actual patient.

[New approaches to hygienic assessment of machines used in the construction of railways].

The stock of railway machines has been greatly replaced by that new-generation ones that have a high capacity and can themselves move at high speeds. This changes the working conditions of the staff and the conditions of their driving. The new conditions promotes the development of new standard requirements and the methods of tests and assessing the indices of unfavorable working conditions.

[Experience in hygienic and ergonomic design of an inter-regional high-speed electric train "Sokol"].

The fundamental hygienic principles in the design of a high-speed Sokol electric train and its ergonometric approach cause one to anticipate a new rolling stock with high convenience for passengers, which will be an analogue of the world's best ones to appear.
