The gravimetric and electrochemical tests are the most common techniques used in determining the corrosion rate. However, the use of electrochemical polarization is limited to electrolytes with sufficient conductivity for which Tafel curves are linear. In this study, we investigated a technique in which working microelectrodes of AISI 1020 steel were used to obtain the Tafel curves in diesel oil. The strategy was to reduce the electrode area and hence the ohmic drop. The diameter of the microelectrode was reduced to a value where the compensation of the Tafel curves became unnecessary. The results showed that for electrodes with diameters below 50 μm, the ohmic drop tends to a minimum and independent of the microelectrode diameter.

The purpose of this study was to evaluate the effects of a pedagogical intervention to improve the reading comprehension of fourth grade students of a public primary school. Two classes of 28 students were randomly assigned to an experimental or control group. The students were assessed during three different moments by means of an informative questionnaire, a Learning Strategies Scale and two cloze tests for reading comprehension. The intervention consisted of seven sessions which included learning strategies instruction, reading strategies instruction, meta-cognition activation, motivational support and study guidance. Results showed improvement in meta-cognition and in reading comprehension in both groups. However, gains were higher and more consistent in the experimental group.
