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: 1.2 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: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

要約

The process of surface generation due to breakage of fluids is considered with respect to the limiting relationship between the input energy for breakage and the resulting surface energy output. A new thermodynamic law is formulated, stating that the energy required for breakage of the fluid into detached fragments cannot be converted completely to surface energy. This law is presented in four alternative forms that predict the existence of a maximum in the surface energy between the initial and final states of the fluid, and formation of a hysteresis loop in a complete breakage and coalescence cycle. Analysis of deformation and breakage of a sphere and an infinitely long cylinder outlines some implications of the law. It is shown that in both cases a range of configurational instability exists. In contrast to Rayleigh instability that evolves from small perturbations, the configurational instability is reached at significant deformation levels. The conditions for enhanced efficiency of surface energy generation are discussed, and it is shown that the smaller the deviation of the fragments are from sphericity is, the higher is the expected efficiency.
