The model is function of mechanical and physical variables that depend not only on the vehicle but also on the ground. This toolbox can be extended to GPS tracking files by means of reading data file plug-ins. Even standard drive cycles can be simulated. Battery and hydrogen consumption, hydrogen storage tank level, battery state of charge, power consumption and fuel cell energy production, maximum range and maximum number of cycles for a real route can be determined. The model facilitates the prediction of the vehicle range and the hydrogen and energy consumption. Real route simulation gives a good approximation of the vehicle speed close to real-life services instead of using driving cycles that are quite arbitrary approximations to a real route.

After verifying the effectiveness of the simulated process, the next step was to carry out an economic analysis at the level of equipment to assess the economic viability of the simulated recovery plant.

Rheological studies include determination of the following: (a) flow curves with a controlled shear rate or shear stress, and (b) curves showing the time and temperature dependence of apparent viscosity. Apparent viscosity was correlated using the power-law model. The flow behaviour index, n, and the consistency index, K, were calculated and their variation with the temperature (between 20 and 40°C) was studied. Their values varied between 0.19 and 0.51, for n, and between 2.39 and 60.5, for K.

The different sauces were divided into sweet and salad, and for each sausage the behavior was studied at different temperatures. The power-law parameters, n and k, for sauces were calculated and their variation with the temperature was studied. On the other hand, the activation energy was calculated for the sweet sauces.

This paper describes an expanded framework to help chemical educators to construct a quiz for solution of chemical exercises in their courses. The novelty of this contribution is that the proposed tool combines a flashcards-based method with knowledge pills. The framework
