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

要約

In this paper, in vitro experimental research results of the hydrodynamic noise of open and semi-closed bileaflet prosthetic mitral valve are presented. The bileaflet valve Sorin biomedica cardio was used in this research. Group of pressure fluctuation sensors and sensors of absolute pressure registered noise of the vortex structures and the jet flow. For the open bileaflet valve, the mean pressures are higher near the side jet than near the central jet. The lowest mean pressures occur near the side jet downstream to the semi-closed valve. Spectral levels of the pressure fluctuations significantly varied for different flow rate in the frequency range from 0.03 Hz to 200 Hz. For the semi-closed valve near the side jet, the power spectral densities of the pressure fluctuations are (3...4) times greater than for the open one. It was found that hydroacoustic measurements could be an effective basis for developing diagnostic equipment in order to check the use of the bileaflet prosthetic mitral valve.
