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

Independent control of the temporally averaged liquid flow rate and the droplet size spectrum emitted from hydraulic atomizers was achieved by coupling control of liquid supply pressure and pulse-width modulation (PWM) of instantaneous nozzle flow. Experimental results for a number of atomizer types, typical of agrochemical spraying, indicated that 10:1 flow turndown ratios could be achieved affixed liquid supply pressures. Such capability is useful when a wide range of application rate and rapid response are desired. The spray droplet volume median diameter of emitted spray could be concurrently controlled over a two- to threefold range. The technique is useful when off-target movement of spray material can be reduced by decreasing the volume fraction of spray material contained in small droplets. The dynamic control range allowed eightfold reductions in the spray volume contained in droplets less than 105 μm diameter. The technique was designed for integration into spray application controllers with flow and pressure feedback loops. The technique is limited to spray applications where the nozzle flow is the predominant mechanism for atomization. In situations such as high-speed air flow past a nozzle, the secondary breakup of the emitted spray can reduce the effectiveness of the technique significantly.
