Since the publication of the Bass model in 1969, research on the modelling of the diffusion of innovation resulted in a vast body of scientific literature consisting of articles, books, and studies of real-world applications of this model.The main objective of the diffusion model is to describe a pattern of spread of innovation among potential adop
Influence of the Jet End Shape at the Jet Impact on the Liquid Surface
The paper presents the results of a numerical simulation of water jet (250 m/s) impact onto the surface of motionless liquid (water).The main attention has been paid to the influence of the jet end shape on the liquid dynamics in the vicinity of the impact site.This is of interest for the applications characterized by the destructive action of a li
The measuring of working time and its challenges
Through an analysis of European case-law on working time, the Author points out that the adoption by the Member States of Rug a system of objective, reliable and accessible measurement of working time (while exercising their discretion as to how the measurement system is to be implemented, taking into account, where appropriate, the specificities o
Dosimetric comparison between RapidArc and HyperArc techniques in salvage stereotactic body radiation therapy for recurrent nasopharyngeal carcinoma
Abstract Background To evaluate dosimetric differences of salvage irradiations using two commercially available volumetric modulated arc therapy (VMAT) stereotactic body radiation therapy (SBRT) techniques: RapidArc (RA) and HyperArc (HA), for recurrent nasopharyngeal carcinoma (NPC) after initial radiation therapy.Methods Ten patients with recurre
