Evidence regarding the effectiveness of continuing medical education (CME) is reviewed in terms three possible end- products : physician competence, performance, and patient health status. Results this review are presented context recent increases mandatory CME policies corresponding cost such to nation. The number activities evidently on increase. Yet, according conventional wisdom, not effective. To contrary, about half 47 evaluation studies published since 1960 reported demonstrable...
Accidental freezing of vaccines is a growing threat and real risk for national immunization programs when the potency many can be compromised if these are exposed to sub-zero temperatures in cold chain. In Tunisia, this issue compounded by using sub-standard domestic chain equipment instead equipping program with medical refrigerators designed specifically storing temperature sensitive pharmaceuticals. Against backdrop, paper presents findings demonstration project conducted Tunisia 2012...
This paper describes an approach piloted in the Kasserine region of Tunisia to increase energy efficiency distribution vaccines and temperature sensitive drugs. The objectives approach, known as 'net zero energy' (NZE) supply chain were demonstrated within first year operation. existing system was modified store medicines same buildings transport them according pre-scheduled optimized delivery circuits. Electric utility vehicles, dedicated integrated medicines, improved regularity...
During the past decade, medical educators have spent time discussing and attempting to define competence. There appears be some confusion as why definitions of competence are important how one might describe in a logical fashion elements for physicians. Here, we try clarify what is meant by competence, value students, educators, institutions public, provide conceptualization definition medicine.
Abstract We describe a spectrum splitting solar module design approach using ensembles of 2–20 subcells with bandgaps optimized for the AM 1.5D spectrum. Device physics calculations and experimental data determine radiative efficiency parameters III ‐V compound semiconductor enable modification conventional detailed balance to predict while retaining computational speed wide search space. Accounting nonideal absorption recombination rates due realistic material imperfections allows us...
A stationary catadioptric concentrating photovoltaic module with aperture area over 100 cm2, geometric concentration of 180×, and collection within 60° polar incidence was designed, prototyped, characterized. The performance followed modeling closely a peak power conversion efficiency 26% for direct irradiance. Tracking the sun is accomplished via translational micro-tracking completely internal to module, avoiding cost complexity mechanical two-axis trackers that point towards sun. This...
Despite demonstrated efficacy of vaccines against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent coronavirus disease-2019 (COVID-19), widespread hesitancy to vaccination persists. Improved knowledge regarding frequency, severity, and duration vaccine-associated symptoms may help reduce hesitancy. In this prospective observational study, we studied 1032 healthcare workers who received both doses Pfizer-BioNTech SARS-CoV-2 mRNA vaccine completed post-vaccine...
While monolithic multijunction solar cell approaches have been quite successful, current and lattice matching requirements limit the maximum possible achievable efficiencies. Spectrum splitting, where light is optically distributed among subcells with differing bandgaps, avoids these constraints offers a route to achieving higher efficiencies (<50%). We investigate spectrum splitting approach concentrated sunlight trapped in textured dielectric slab then selectively coupled into...
