Annotation. This article discusses a two-mass system with a rigid fixation of the end part (foundation) of the bridge on high-speed railways. The results of selecting the optimal parameters of dynamic vibration dampers (DVDs) for setting stiffness and damping in the case of a two-mass system with a rigidly fixed end part of the bridge are presented. It is shown that such a solution is recommended for the case when the bridge is located in a steep gorge, the intermediate supports are high and flexible, and the end supports are quite rigid, since they give the designer a wide opportunity to choose the dimensions and rigidity of the designed seismic protection elements.

Sella turcica is a saddle shaped bony structure present on the sphenoid bone. The pituitary gland is seated at the inferior aspect of the sella turcica, called hypophyseal fossa. Sella turcica serves as a cephalometric landmark, that being said any morphological changes can affect the overall craniometry of the individual as well as alter the function of the structures it lodges. The following review emphasis on the possible morphological changes of sella turcica and its effects on the individual.
