European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 4, Pages 333-337

Infill walls are inescapable components of a few structures to make detachment among interior space and exterior condition. Generally, here are a few rife notches inside the infill walls because of practical requirements, architectural contemplations or artistic contemplations. In present intended carry out, might and firmness involvement of infill walls aren't thought of. Though, the occurrence of infill walls might impact the seismic reaction of structures exposed to earthquake loads and cause a conduct which is not the same as that anticipated for a bare frame. Additionally, partial openings inside infill walls are important constraint influencing the seismic behavior of unfilled frames in this manner diminishing lateral stiffness and strength. Past specialists have attempted to discover through tests and logically the impact of numerous parameters, such as notch size and locality, proportion of opening, association among outlined and infill wall, flexible feature in surround member, textile property, malfunction mode, and so forth on in filled frames behavior. The present article is planned to think about different models of structures considering the openings at various areas in the infill walls for the seismic conduct. The investigation could encourage trendy and code developers in choosing and suggesting appropriate diagnostic representation for evaluating power, hardness, breakdown modes and different assets of infill frames with openings.

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.

IMPORTANE OF THE ALTITUDE INDEX IN THE DIAGNOSTICS OF FRACTURES OF THE CALCANEUS IN CHILDREN

Abstract. More often, the injuries happenas a result of direct trauma, and are rarely
caused by non-direct actiontraumatic force. The definition of tarano-calcaneus corner and
higher index (rentgenological) has great influence on diagnostics and on curing calcaneus
bones in children.On moderate displacement, closed reposition with the skeleton stretching
or compression apparatus distinction osteosinthesis is recommended.On crude
displacement, it is recommended to perform operative treatment and replace defects of
bones bytissues free auto-transplantation

This paper describes the stiffness characteristics of a 3-PUU translational parallel kinematic
machine (PKM). An alternative method of generating the stiffness matrix is used when
considering actuators and limitations, as well as the compliances of both actuators and legs.
Extreme stiffness values and their design consequences are used to evaluate rigidity
manipulator performance.
Using the stiffness of a 3-PUU PKM in the design of its architecture is a good idea. Using an
eigenscrew decomposition of the PKM's stiffness matrix, it is possible to identify the PKM's
stiffness centre and the PKM's compliant axis, which provides a physical interpretation of
PKM stiffness.
