Forskningsöversikt (refereegranskat)abstract
- For the past several years, the JET scientific programme (Pamela et al 2007 Fusion Eng. Des. 82 590) has been engaged in a multi-campaign effort, including experiments in D, H and T, leading up to 2020 and the first experiments with 50%/50% D-T mixtures since 1997 and the first ever D-T plasmas with the ITER mix of plasma-facing component materials. For this purpose, a concerted physics and technology programme was launched with a view to prepare the D-T campaign (DTE2). This paper addresses the key elements developed by the JET programme directly contributing to the D-T preparation. This intense preparation includes the review of the physics basis for the D-T operational scenarios, including the fusion power predictions through first principle and integrated modelling, and the impact of isotopes in the operation and physics of D-T plasmas (thermal and particle transport, high confinement mode (H-mode) access, Be and W erosion, fuel recovery, etc). This effort also requires improving several aspects of plasma operation for DTE2, such as real time control schemes, heat load control, disruption avoidance and a mitigation system (including the installation of a new shattered pellet injector), novel ion cyclotron resonance heating schemes (such as the three-ions scheme), new diagnostics (neutron camera and spectrometer, active Alfven eigenmode antennas, neutral gauges, radiation hard imaging systems...) and the calibration of the JET neutron diagnostics at 14 MeV for accurate fusion power measurement. The active preparation of JET for the 2020 D-T campaign provides an incomparable source of information and a basis for the future D-T operation of ITER, and it is also foreseen that a large number of key physics issues will be addressed in support of burning plasmas.

Oxygen consumption calorimetry, William Parker: 2016 DiNenno Prize

Tidskriftsartikel (refereegranskat)abstract
- The 2016 DiNenno Prize recognizes oxygen consumption calorimetry as a significant technical achievement that has had a major impact on public safety. Oxygen consumption calorimetry has made the measurement of heat release rate of a fire a routine part of fire testing for both research and for regulatory compliance. Heat release rate is a primary metric of fire size which is foundational in modern fire protection engineering. The 2016 Philip J. DiNenno Prize is awarded to Dr. William Parker, with ample commendation to his deceased collaborator, Dr. Clayton Huggett. Others who made contributions to the early development and application of oxygen consumption calorimetry include Peter Hinkley, William Christian, Thomas Waterman, Darryl Sensenig, Ralph Krause, Richard Gann, Vyto Babrauskas, Gunnar Heskestad, Norm Alvares, Donald Beason, and Brady Williamson. This review presents an overview of the background to the technological development and its impact on public safety

- The National Fire Protection Association has recognized fast-response sprinkler technology, developed and promulgated by Factory Mutual Research Corporation (FMRC, now FM Global), with its 2019 Phillip J. DiNenno Prize. This technology was the result of three innovative efforts that produced Response-Time Index (RTI), quick-response (QR) residential sprinklers, and the Early Suppression, Fast Response (ESFR) sprinkler. Cheng Yao (deceased), who led sprinkler research at FMRC (now FM Global), was the prime mover for this work. Dr. Gunnar Heskestad was responsible for conceptual work and much of the research and development work for RTI, as well as a good deal of the underlying research for ESFR. Dr. Hsiang-Cheng Kung did the conceptual and R&D work for QR residential sprinklers and along with Harry Shaw (deceased) supported and advocated for their acceptance into codes; he also conducted a significant amount of research work for ESFR development. Dr. Robert G. Bill provided additional experimental research work for RTI, including the adaptation of the RTI wind tunnel for testing recessed, flush and concealed sprinklers, as well as support work for Heskestad’s proposed resolution to the conduction complication identified by Jerome Pepi (deceased). He also worked extensively and closely with Roger L. Allard who was instrumental in gaining global acceptance and promulgation of these technologies worldwide. As the DiNenno Prize is not awarded posthumously, only those individuals identified in bold text were awarded the prize.

- - In October 2017, the International Olympic Committee hosted an international expert group of physiotherapists and orthopaedic surgeons who specialise in treating and researching paediatric ACL injuries. Representatives from the American Orthopaedic Society for Sports Medicine, European Paediatric Orthopaedic Society, European Society for Sports Traumatology, Knee Surgery & Arthroscopy, International Society of Arthroscopy Knee Surgery and Orthopaedic Sports Medicine, Pediatric Orthopaedic Society of North America and Sociedad Latinoamericana de Artroscopia, Rodilla y Deporte attended. Physiotherapists and orthopaedic surgeons with clinical and research experience in the field, and an ethics expert with substantial experience in the area of sports injuries also participated. Injury management is challenging in the current landscape of clinical uncertainty and limited scientific knowledge. Injury management decisions also occur against the backdrop of the complexity of shared decision-making with children and the potential long-term ramifications of the injury. This consensus statement addresses six fundamental clinical questions regarding the prevention, diagnosis and management of paediatric ACL injuries. The aim of this consensus statement is to provide a comprehensive, evidence-informed summary to support the clinician, and help children with ACL injury and their parents/guardians make the best possible decisions. © 2019
