High Temperature Electrolysis at EIFER, Main Achievements at Cell and Stack Level

Characteristic Points of Stress-Strain Curve at High Temperature

Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...

Mathematics Education Research at University Level: Achievements and Challenges

In this text, associated with my opening lecture at the first INDRUM Conference, I will reflect on the achievements and challenges of mathematics education research at university level, in the light of my experience both as a researcher and a university teacher. First, I will come back to the historical evolution of this field of research through the retrospective analysis of some selected epis...

A Numerical Simulation of Inspiratory Airflow in Human Airways during Exercise at Sea Level and at High Altitude

At high altitudes, the air pressure is much lower than it is at sea level and contains fewer oxygen molecules and less oxygen is taken in at each breath. This requires deeper and rapid breathing to get the same amount of oxygen into the blood stream compared to breathing in air at sea level. Exercises increase the oxygen demand and make breathing more difficult at high altitude. In this study, ...
