Objective: To compare the impact of examination feedback versus access to historical examination questions on information retention.
Methods: First-year student-pharmacists completed a baseline knowledge assessment composed of 30 examination questions divided into three conditions of 10 questions each. In the CHEAT condition, students were provided with 10 questions and their correct answers ahead of time.
Vanadium redox flow batteries have applications for large-scale electricity storage. This paper reports the influence of carbon structural characteristics of sustainable walnut shell-derived carbons in carbon/polyvinylidene fluoride composite electrodes on vanadium redox reactions. Pyrolysis, gasification, and chemical treatment procedures were used to modify the structural characteristics of carbons.

A microwave-assisted activation procedure was adopted to assess the impact on the CO capture capacity of the resulting AC using both a lower temperature (400 °C vs. 700 °C) and a shorter duration (5 vs.

When target T cells are limiting, the virus can evolve to infect cells with a low density of CD4 such as macrophages (M-tropic). The entry phenotype is known to be encoded in the viral Env protein on the surface of the virus particle.
