THIRD PART: STUDENT PRESENTATIONS

VISIT TO A COMPANY

Testi/Bibliografia

The lesson's notes will be fundamental.

Teaching material (scientific books, literature articles and power point presentations) will be distributed during lessons and it will available on line (Moodle platform).

Among suggested books: Biomaterials Science: An Introduction to Materials in Medicine, Buddy D. Ratner, Academic Press.

Metodi didattici

Room lectures.

The students will be provided with copy of the material shown during lecturing.

Presentations will be available for the students through Moodle platform.

Short presentations of researchers from both industrial and public healthcare structures, will be planned during lessons, to illustrate professional experiences and to examine in depth specific thematics.

A visit to a company of the Biomedical District in Mirandola will be performed.

Students will be invited to prepare power point presentations on specific themes to illustrate during the lessons.

Attendance to course lessons is strongly recommended to understand the most fundamental aspects of the subject and the correlations among the different parts of the programme.

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas] online, while Module 3 on health and safety is to be attended in class. Information about Module 3 attendance schedule is available on the website of your degree programme.

Modalità di verifica e valutazione dell'apprendimento

Learning assessment is based on oral examination at the end of the course. The oral examination will last around 30 minutes.

The oral examination will take into account the ability of the student to make connections among the various parts of the course programme and to design polymeric materials and products for specific applications in the biomedcal field, on the basis of the acquired knowledge.

Questions, during the examination, will be related to the following main program sections: (a) knowledge of the definition of biocompatible, bio-inert and bio-active material; (b) knowledge of the interaction among polymeric materials (both synthetic and natural) and the biological tissues of the human body. (c) design of the biomedical device suitable for the specific application, starting from the right choice of the polymeric material; (d) processing of the polymeric materials to produce biomedical devices; (e) potential scientific and social feedback of the use of specific categories of polymeric materials in the biomedical and biotechnological field.

The final mark will be based also on the presentations that students will prepare during the lessons.

Good language properties and the ability to make connections among the different parts of the programme will involve a higher score.

Strumenti a supporto della didattica

Lectures with the aid of PC, projector.

Short presentations of researchers from both industrial and public healthcare structures, will be planned during lessons, to illustrate professional experiences and to examine in depth specific thematics.
