Acknowledgements and Additional Notices (related to the J NED Special Issue 'Trends and Perspectives in Nuclear Thermal-hydraulics')

The decision to propose publishing the Special Issue (SI) was taken around February 2019; the importance of having it ready in time for the next International Topical Meeting on Nuclear Reactor Thermal Hydraulics (NURETH-18), to be held in August 2019, soon became clear. This left very little time for concluding formal agreements, sending out invitations to authors, the subsequent preparation of the papers by the authors, the review process and ensuing publication. All this required a special commitment by the actors, authors, reviewers, editors and editorial staff involved. Sincere thanks are due first of all to the authors of the papers, including the commemorations. Their readiness to honor the memory of Bal Raj Sehgal, George Yadigaroglu and Geoffrey Hewitt is noted. The names of all the authors can be found in the list of contents. Contact authors, leading authors and scientists who stimulated the papers are listed in alphabetical order.
