Use of generic medicines in Latvia : Awareness, opinions and experiences of the population
Funding Information: Funding was provided by EEA Financial Mechanism and Latvian state (award number 2012.EEZ/DAP/MIC/183). The project is financially supported by Iceland, Liechtenstein and Norway. Publisher Copyright: © 2019 The Author(s).Background: To stimulate use of generic medicines a combination of supply and demand side mechanisms are employed in the Latvian reimbursement system. It is reported that patients have high out-of-pocket pharmaceutical spending and that they overpay by not choosing generic medicines. Patient preferences may be an important obstacle in implementing generic policy. Objective of this study was to assess awareness, opinions and experience of the Latvian population regarding use of generic medicines. Methods: Survey of representative sample of the population of Latvia (n = 1005) aged 18-74 was conducted in March 2015. The survey was distributed in Latvian and Russian languages using Computer Assisted Web Interviews. Associations between experience with generic medicines, preference for medicines, and sociodemographic variables were tested with Pearson Chi-square statistics. Associations between the previous experience and information given by different sources versus choice between medicines were tested with Spearman's correlation test. Results: 72.3% of the population were informed about generic medicines. Men (66.9%) and respondents with primary or secondary education (58.3%; 69.3%) were less informed compared to total (72.3%). From those who recalled using generic medicines (n = 441), 94.4% evaluated their experience as positive or neutral. Despite this, only 21% of the population would opt for generic medicines. The strongest preference for brand-name medicines was in the age group > 55 (40.5%). Opinion of a physician was the most important factor when choosing between generic and brand-name medicines (88.7%). The more positive the information provided by general practitioners, physician specialists, pharmacists, family members, friends and internet is perceived, the more likely respondents are to choose generic medicines (p < 0.001). Conclusion: This study demonstrates that people in Latvia are aware of generic medicines but only a minority of the population would choose them when presented with a choice. It is therefore important that health care professionals provide objective and unbiased information about generic medicines to their patients. Interventions should aim to reach groups that are less informed and to improve providers' understanding and communication with patients about generics.publishersversionPeer reviewe

Model for screening of resonant magnetic perturbations by plasma in a realistic tokamak geometry and its impact on divertor strike points
This work addresses the question of the relation between strike-point
splitting and magnetic stochasticity at the edge of a poloidally diverted
tokamak in the presence of externally imposed magnetic perturbations. More
specifically, ad-hoc helical current sheets are introduced in order to mimic a
hypothetical screening of the external resonant magnetic perturbations by the
plasma. These current sheets, which suppress magnetic islands, are found to
reduce the amount of splitting expected at the target, which suggests that
screening effects should be observable experimentally. Multiple screening
current sheets reinforce each other, i.e. less current relative to the case of
only one current sheet is required to screen the perturbation.Comment: Accepted in the Proceedings of the 19th International Conference on
Plasma Surface Interactions, to be published in Journal of Nuclear Materials.

Modelling of the effect of ELMs on fuel retention at the bulk W divertor of JET
Effect of ELMs on fuel retention at the bulk W target of JET ITER-Like Wall was studied with multi-scale calculations. Plasma input parameters were taken from ELMy H-mode plasma experiment. The energetic intra-ELM fuel particles get implanted and create near-surface defects up to depths of few tens of nm, which act as the main fuel trapping sites during ELMs. Clustering of implantation-induced vacancies were found to take place. The incoming flux of inter-ELM plasma particles increases the different filling levels of trapped fuel in defects. The temperature increase of the W target during the pulse increases the fuel detrapping rate. The inter-ELM fuel particle flux refills the partially emptied trapping sites and fills new sites. This leads to a competing effect on the retention and release rates of the implanted particles. At high temperatures the main retention appeared in larger vacancy clusters due to increased clustering rate
