Compulsory
2nd Cycle Studies - Mestrado
Recommended Prerequisites
Appropriate completed 1st cycle
Teaching Methods
Presentation of the material by the Professors in classical teaching classes. These will also involve the active participation of the students. The laboratory component will involve performing both practical and theoretical studies. There will also be a component involving final presentation of a written themed monograph (which could be associated with one of the laboratory studies which was carried out) and which will be made by the student at the end of the semester.
Learning Outcomes
Recognize and apply basic princilpes and concepts of chemistray in the area of explosives and ballistics. Analyse, synthesise and understand essential concepts so that you can provide a judgement in this domain.
Acquire competences which will allow you to communicate the information obtained in a clear fashion and with an appropriate presentation with both specialists and nonspecialists in the area in a clear and unambiguous fashion. Know how to estabish and justify decisions taken. Know how to apply your knowledge to resolve problems in forensics.
