GENERAL AND SPECIFIC COMPETENCE
Acquisition of basic knowledge of properties of powder systems, sampling methods and operations with powder systems necessary for scientific research.
STUDENTS' TEACHING OBLIGATIONS AND THEIR PERFORMANCE
Regular participation in classes (lectures, seminars and lab tutorials), minimum attendance 80% . Writing papers, homework and seminar assignments.
TEACHING METHODS
Lectures and seminars.
KNOWLEDGE TESTING AND EVALUATION
Continuous assessment of knowledge through two partial written examinations. The final grade will be composed of points from exams (80%), attendance (5%), and online course activities (self-tests, quizzes, games, homework, seminar assignments, 15%).
