Grit and Resilience in WLSPs: The Potential of Blending Translation and Indirect Service Learning

This study explores how blending translation with service learning has the potential to support the development of grit and resilience. The participants collaborated on translating documents from English to Spanish for local organizations, as part of a service learning component of an advanced Spanish grammar course. Using reflection papers written by students at the end of the semester, the study adopted a qualitative interpretive approach to examine their perspectives. Students were asked to consider the skills they developed, share their perceptions of the value of the translations for the community and for themselves, and reflect on the emotions they experienced when they encountered and coped with challenges. Data analysis reveals that the service learning translations supported the development of the two dimensions of grit and cultivated resilience: students developed various adaptive strategies and stayed interested in the task despite the possibility of failure. Resilience emerged from their focus on the partners and community’s needs and the production of professional documents

Numerical inverse Laplace transformation for determining the system response of linear systems in the time domain

An algorithm is described that is based on the method of breaking the Laplace transform down into partial fractions which are then inverse-transformed separately. The sum of the resulting partial functions is the wanted time function. Any problems caused by equation system forms are largely limited by appropriate normalization using an auxiliary parameter. The practical limits of program application are reached when the degree of the denominator of the Laplace transform is seven to eight

Knowledge and Use of Paced Bottle-Feeding Among Mothers of Young Infants

Objective: To describe mothers’ awareness and use of paced bottle-feeding (PBF) and to investigate whether the use of PBF was associated with maternal characteristics and infant feeding practices. Methods: Cross-sectional, online survey. Participants were mothers of infants \u3c 12 months of age (n =197). Participants self-reported their awareness and use of PBF, demographic characteristics, and infant feeding practices. Results: Of the 41% of participants who indicated they had or maybe had heard of PBF, 23% used PBF and 35% sometimes used PBF. Use of PBF was not associated with mother or infant characteristics. Participants who used PBF were significantly less likely to encourage their infant to finish the bottle (odds ratio,0.04; 95% confidence interval, 0.01−0.79). Conclusions and Implications: Paced bottle-feeding was associated with lower likelihood of one dimension of pressuring feeding practices, encouraging infant bottle-emptying. More research is needed to determine the effectiveness of PBF in promoting healthy feeding outcomes

Main chamber wall plasma loads in JET-ITER-like wall at high radiated fraction

Future tokamak reactors of conventional design will require high levels of exhaust power dissipation (more than 90% of the input power) if power densities at the divertor targets are to remain compatible with active cooling. Impurity seeded H-mode discharges in JET-ITER-like Wall (ILW) have reached a max- imum radiative fraction ( F rad ) of ∼75%. Divertor Langmuir probe (LP) measurements in these discharges indicate, however, that less than ∼3% of the thermal plasma power reaches the targets, suggesting a missing channel for power loss. This paper presents experimental evidence from limiter LP for enhanced cross-field particle fluxes on the main chamber walls at high F rad . In H-mode nitrogen-seeded discharges with F rad increasing from ∼30% to up to ∼75%, the main chamber wall particle fluence rises by a factor ∼3 while the divertor plasma fluence drops by one order of magnitude. Contribution of main chamber wall particle losses to detachment, as suggested by EDGE2D-EIRENE modeling, is not sufficient to explain the magnitude of the observed divertor fluence reduction. An intermediate detached case obtained at F rad ∼60% with neon seeding is also presented. Heat loads were measured using the main chamber wall thermocouples. Comparison between thermocouple and bolometry measurements shows that the frac- tion of the input power transported to the main chamber wall remains below ∼5%, whatever the divertor detachment state is. Main chamber sputtering of beryllium by deuterium is reduced in detached condi- tions only on the low field side. If the fraction of power exhaust dissipated to the main chamber wall by cross-field transport in future reactors is similar to the JET-ILW levels, wall plasma power loading should not be an issue. However, other contributions such as charge exchange may be a problem.EURATOM 63305

An FPGA-based bolometer for the MAST-U Super-X divertor

A new resistive bolometer system has been developed for MAST-Upgrade. It will measure radiated power in the new Super-X divertor, with millisecond time resolution, along 16 vertical and 16 horizontal lines of sight. The system uses a Xilinx Zynq-7000 series Field-Programmable Gate Array (FPGA) in the D-TACQ ACQ2106 carrier to perform real time data acquisition and signal processing. The FPGA enables AC-synchronous detection using high performance digital filtering to achieve a high signal-to-noise ratio and will be able to output processed data in real time with millisecond latency. The system has been installed on 8 previously unused channels of the JET vertical bolometer system. Initial results suggest good agreement with data from existing vertical channels but with higher bandwidth and signal-to-noise ratio.Engineering and Physical Sciences Research Council EP/L01663X/1EURATOM 63305
