Understanding the changes in multiphase flow parameters caused by mineral dissolution-precipitation is required for multiple applications ranging from geological storage of CO2, enhanced geothermal energy production or ...

Images (for example, photomicrographs) are routinely used as qualitative evidence of the microstructure of foods. In quantitative image analysis it is important to estimate the area (or volume) to be sampled, the field of ...

Functions represent a very important area of study in mathematics due their wide range of applications in many areas of knowledge. Functions can be approached in concrete and meaningful ways. However, school textbooks often ...

This thesis represents a didactic research linked to the Post-graduation Programme in Education of the Universidade Federal do Rio Grande do Norte which aimed to approach the construction of the geometrical concepts of ...

The use of literature in the didactic book of the Portuguese language in the first years of elementary school was the object of this research, that aimed at identifying the literary texts found in didactic collections and ...

A multiphase and multigrain mathematical model for the solidification of binary alloys is proposed, implemented, and validated. The model equations are derived using the volume averaging method and considering the conservation ...
