The protection by coatings constitutes the most used method of anticorrosive combat, given its effectiveness, economy, universality and ease of application. However, the use of these coatings at an industrial level entails a high consumption of energy and chemical products, as well as a marked environmental impact. One of the ways to minimize the negative effects in this type of process is the use of corrosion inhibitors. This work had the objective of showing the results of an investigation in which an evaluation was carried out for the introduction of corrosion inhibitors in the acid pickling operation of a galvanic workshop. As research methods and techniques, documentary review, observation, experimental studies were used, in addition, mathematical modeling techniques and process optimization were applied. The main results were: the demonstration of the feasibility of the use of form...

Based on the need to make accurate decisions in the face of the COVID-19 pandemic in Peru, pandemic in Peru, specifically for the recovery of the tourism sector. For this purpose, a characterization of the behavior of the pandemic was carried out in the first three months of its development, based on the analysis of trends and the determination of the effective reproduction number (Rt) from statistical-mathematical methods. A variant of the SIR mathematical model was applied to forecast the possible evolution of the pandemic. This model was adjusted with the GlobalSearch optimization strategy of the MATLAB software. His solution used the MATLAB function ode23tb, which uses a combined Runge-Kutta algorithm with a trapezoidal rule algorithm. With the application of the Kaizen strategy as a means of continuous improvement, a set of actions were proposed that could be carried out today and t...
