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

RESUMO

Increasing spray deposition while reducing inadvertent off-target movement is critical with agricultural sprays for field protection of crops. Pulsed flow can increase droplet velocity and energy while maintaining desired droplet size spectra from simple-orifice atomizers. Droplet size spectra and velocities were measured using a phase Doppler laser system for hydraulic atomizing nozzles producing liquid flow of 1.1 liters/min while pressurized at 50–670 kPa. Typical spray cloud volume median diameters ranged from 210 to 337 mm. Droplet velocities in the droplet diameter range of 150 to 400 mm were increased by 3- to 4-fold, corresponding to a 9- to 16-fold increase in kinetic energy of the spray droplets in that size range. The cumulative momentum and kinetic energy of the entire spray cloud were increased by 2-fold and 4.4-fold, respectively. The results confirmed that droplet size spectra could be maintained for adequate target coverage while droplet velocities could be increased to reduce droplet flight times and provide greater kinetic energy for deposition.
