RESUMO
Voltage data acquired after probe signal transmitted through the organic film and reflected off the film surface as a function of 0.36 mW millimeter wave signal frequency in the range 110-160 GHz. Five different organic photovoltaic (OPV) materials and one 95:5 blend produced at 2 spin rates are used. These materials are a) fluorinated 2-alkyl-benzol[d] [1-3]triazole (FTAZ), a high hole-mobility polymer used for transistors and photovoltaics, b) diketopyrrolopyrrole (DPP3T), an acceptor polymer used in field-effect transistors (FET), c) Y5(PffBT4T-2OD) film that possesses remarkable temperature controllable morphology, d) a neat conjugated polymer P3HT, Poly(3-(hexylthiophene-2,5diyl) film that is used in optoelectronic devices and as a conductive binder for Li-ion batteries, e) phenyl-C61-butyric acid methyl ester (PCBM) films and its soluble derivatives used as n-type organic semiconductors, and f) excitonic photovoltaic material 95%:5% donor-acceptor blend P3HT:PCBM produced by 2 different spin rates. Measurement of direct-current (dc) transmitted and reflected power (RF voltage signal) are measured using a newly developed continuous wave (CW) D-waveguide band probe (110-160 GHz) apparatus named time-resolved millimeter wave conductivity (TR-mmWC) [1]. Transmission and first surface reflection voltages are captured by a zero-bias Schottky barrier diode (ZBD) and converted to relevant dc voltages. Original voltage signal datasets attached with this can be utilized for photovoltaic, dielectric property estimation, and other semiconductor physics applications. A manually collected dataset of transmission and reflection coefficient at incident probe power level â¼0.9 mW for 95:5 P3HT:PCBM films produced at 2 different spin rates, and one separately only for the neat P3HT film are also presented here in tabular form.
RESUMO
PURPOSE: Medical training has traditionally focused on the proximate determinants of disease, with little focus on how social conditions influence health. The authors conducted a scoping review of existing curricula to understand the current programs designed to teach primary care residents about the social determinants of health (SDH). METHOD: In January and March 2017, the authors searched seven databases. Eligible articles focused on primary care residents, described a curriculum related to SDH, were published between January 2007 and January 2017, and were based in the United States. RESULTS: Of the initial 5,523 articles identified, 43 met study eligibility criteria. Most programs (29; 67%) were in internal medicine. Sixteen studies (37%) described the curriculum development process. Overall, 20 programs (47%) were short or one-time sessions, and 15 (35%) were longitudinal programs lasting at least 6 months. Thirty-two programs (74%) reported teaching SDH content using didactics, 22 (51%) incorporated experiential learning, and many programs (n = 38; 88%) employed both. Most studies reported satisfaction and/or self-perceived changes in knowledge or attitudes. CONCLUSIONS: The authors identified wide variation in curriculum development, implementation, and evaluation. They highlight curricula that considered community and resident needs, used conceptual frameworks or engaged multiple stakeholders to select content, used multiple delivery methods, and focused evaluation on changes in skills or behaviors. This review highlights the need not only for systematic, standardized approaches to developing and delivering SDH curricula but also for developing rigorous evaluation of the curricula, particularly effects on resident behavior.
