Since the installation of an ITER-like wall, the JET programme has focused on the consolidation of ITER design choices and the preparation for ITER operation, with a specific emphasis given to the bulk tungsten melt experiment, which has been crucial for the final decision on the material choice for the day-one tungsten divertor in ITER. Integrated scenarios have been progressed with the re-establishment of long-pulse, high-confinement H-modes by optimizing the magnetic configuration and the use of ICRH to avoid tungsten impurity accumulation. Stationary discharges with detached divertor conditions and small edge localized modes have been demonstrated by nitrogen seeding. The differences in confinement and pedestal behaviour before and after the ITER-like wall installation have been better characterized towards the development of high fusion yield scenarios in DT. Post-mortem analyses of the plasma-facing components have confirmed the previously reported low fuel retention obtained by gas balance and shown that the pattern of deposition within the divertor has changed significantly with respect to the JET carbon wall campaigns due to the absence of thermally activated chemical erosion of beryllium in contrast to carbon. Transport to remote areas is almost absent and two orders of magnitude less material is found in the divertor.

Introduction: Cigarette smoking is a significant public health issue, and the primary cause of preventable health problems in the Greater Toronto Area (GTA). Nevertheless, the prevalence of adolescent smoking remains high. Our proposed study aims to investigate the effectiveness of school-based educational programs in reducing adolescent smoking rates in the GTA. It will compare the results of weekly integrated education sessions offered throughout a school term to more focused, discrete sessions offered at two different points in the term at 10 secondary schools in the GTA. The findings will help inform potential policy and curricular changes to promote smoking cessation among current and future youth. Methods: This study utilizes an experimental quantitative research design. Multi-stage cluster sampling will be used. 10 schools will be selected, with 20 students being recruited per school. The intervention group will receive a school-based education program for smoking cessation, lasting an academic semester. The control group will receive an educational session at the beginning and end of the semester. The inclusion criteria is as follows: participants must be (a) adolescents aged 12-17 and attending an accredited primary or secondary school, (b) living in the GTA, and (c) current daily smokers. The Fagerström Test for Nicotine Dependence (FTND) and biochemical tests will be used to collect pertinent data about smoking cessation rates. Abstinence will also be assessed using the Russell Standard. Results: The study will use statistical tests to compare the proportion of students in the intervention group who quit smoking to the control group. The primary outcome measures will be 4-week and 6-month abstinence counts and nicotine dependency as measured by the FTND. The analysis will be conducted using IBM SPSS ver. 29. Discussion: The results of this study will provide valuable insight into the effectiveness of educational programs in promoting smoking cessation among youth, which will inform the design of future school-based interventions. Additionally, the study will help to understand adolescent smoking patterns, which can be used to guide public health policies. Conclusion:The results will have the potential to inform future education and public health strategies for encouraging adolescent smoking cessation.
