This paper presents a study of wave propagation through an infinite periodic structure that consists of elastic Timoshenko beams interconnected with rigid bodies. This is a generalized approach in which the beams are not coaxial and the centre of mass of each rigid body is placed away from the intersection of their neutral axes. An analytical approach is used by applying the transfer matrix method (TMM), along with the Floquet-Bloch theorem for elastic wave propagation.

Examination was done by the responsible pediatric service of the Primary health care Center Sokolac with help of the humanitarian organization World Vision from Taiwan. The goal of the examination was to get an insight in the general health state of this population, including the risk factor for development of cardiovascular disease (CVD), to suggest appropriate preventive measures, and determine further justification of these examinations within the new organization of health care in RS and B&H.
