Influence of polymer coating on SFCL recovery under load
Gorbunova, D.A.,Kumarov, D.R.,Scherbakov, V.I.,Sim, Kideok,Hwang, Soon The Korea Institute of Applied Superconductivity a 2019 한국초전도저온공학회논문지 Vol.21 No.4
This paper is a study of recovery under load process of superconducting fault current limiter (SFCL). SFCL consists of five parallel-connected high-temperature superconductor (HTS) tapes additionally stabilized by stainless tape. Previously, HTS was heated by current pulse to simulate a short circuit in a power grid. During the cooling period, the current amplitude decreased to 23% or less of HTS critical current value, which is the simulation of network re-switching. When HTS with a polymer coating is cooled, temperature gradient on thermal insulation layer occurs, that prevents a boiling crisis and improves the heat sink into liquid nitrogen. Two samples are coated with a 30 ㎛ and 50 ㎛ polylactide (PLA) layers, reference sample has no polymer coating on it. Samples with a polymer coating show 3-5 times faster cooling than the reference one.

<P>The randomized, phase III AVAPERL trial evaluated the safety and efficacy of bevacizumab maintenance with or without pemetrexed in nonsquamous non–small cell lung cancer (nsNSCLC). Progression-free survival (PFS) was significantly prolonged with bevacizumab–pemetrexed. At a median follow-up of 14.8 months, OS events occurred in 58% of all patients. OS was numerically longer with bevacizumab–pemetrexed versus bevacizumab when measured from randomization (17.1 versus 13.2 months, HR, 0.87 [0.63–1.21]; P=0.29). Second-line therapy was administered in 77% and 70% of patients in the bevacizumab and bevacizumab–pemetrexed arms, respectively.</P>
