The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRAKT

Wave motion of a viscous incompressible liquid in a model of the intraorgan arterial bed consisting of a thin long viscoelastic tube connected in series with a terminal element, characterized by complex wave conductivity, is investigated. Within the framework of an axysymmetrical model of wave motion of the liquid in the thick-walled cylindrical tube the expressions are obtained for the pressure and volume flow waves. For equations averaged over the tube cross-section the expressions for the Riemann invariants and intensities of the incident and reflected compression and expansion waves are obtained. Biomechanical interpretation for pressure-flow dependence and the parameters of the incident and reflected waves are developed by comparing the numerical results. Important diagnostic parameters, allowing to estimate the blood circulation conditions in the viscus upon the measurements of pressure and flow in feeding artery are determined. Wave diagram of pressure and flow variation in aorta and pulmonary arteries is analyzed. The obtained results can be used for developing the innovative non-invasive diagnostic techniques of viscera state estimation.
