The course has the following aims in relation to knowledge and skills to be achieved by the student: i) to know the importance of viscoelasticity and how the strain is modified under shear and extensional stresses; ii) to know the parameters involved in the rheological functions of fluids, particularly in polymer systems; iii) to understand the rehological behaviour of multiphase systems (suspensions, emulsions, polymer mixtures) of chemical, food and cosmetic interest, among others, iv) to know the experimental equipment and advanced hybrid techniques for the determination of structural-rheological processes, and v) to measure experimentally of rheological properties of different kinds of fluids.
The course will combine the mechanical fundamentals with practical applications in the engineering field by means of the study of cases and problems.

Knowledge of the importance in different environments of the rheology (product quality, operation conditions, stability) of mono- and multi-phase systems.
The problems solving, a basic part of the course, require high abstraction capacity of the student.
The practices will allow the knowledge of new techniques and procedures with applications in other technical activities, and also the group work.
Oral presentations will be useful to acquire and practice the oral communication skills.
Scenario 1
The theoretical contents of the course are teaching based on lectures. The seminars will be employed to solve exercises and case studies by both professor and students. Lab sessions will follow the protocols indicated for each practice and the necessary details for equipment operation and experimental techniques. Operation handbooks of viscometers and rheometer are disposal for the students.
At the start of the course the teaching material (program, schedule, content, problems, lab rules, etc.) is disposal for the students.
Lab practices are mandatory.
Scenario 2
In this scenario, the lectures and seminars will be telematically performed by MS Teams and the Virtual Campus.
Scenario 3
All teaching activities will be performed by means of MS Teams and Virtual Campus. Particularly, the lab practices will consist of the visualization of tutorial videos on the use of viscometry and rheometry equipment and data interpretation. Rheology data from different polymer systems taken previously in the lab will be provided for mathematical analysis and telematic oral defense in a tutorial through MS Teams.

Students' learning will be monitored through activities (CB10), works (with oral presentation) (CT4, CG6, CB9) and resolution of problems individually and/or in group (CT5). Lab practices assessment will be from student report (in paper format) and oral defense (CT1, CG7, CG8). The final exam with practical character assesses the corresponding skills to lectures and interactive classes (CE1, CE3, CG1, CB6, CB7).
The only requirement is that the lab practices must be performed and have passed before the exam.
Distribution of the mark (%)
Exam 50%
Works/activities/reports 40%
Tutorials 5%
Professor report 5%
To pass is necessary to achieve 5 points and 3/10 in each part of assessment, excepting Tutorial/Professor report marks.
For second opportunity the accumulative mark of continuous assessment will be maintained. Lab qualifications (including the report) will be retained for the next academic year
This distribution of activities related to assessment will be maintained in the three scenarios.
In cases of fraudulent performance of exercises or exams, the provisions of the Regulations for the assessment of student academic performance and review of marks will be applied.

The language is Spanish.
Virtual course will be employed.
Operation handbooks of viscometers and rheometer are disposal for the students with topics related to safety and health in lab.
The admission of students enrolled in the laboratory of practices requires that they know and comply with the Protocol of Safety Standards in the ETSE labs. This information is available on the ETSE website.
In the activities that are carried out telematically through MS Teams and the Virtual Campus will be used. For these activities it is recommended that the computer equipment have a microphone and a camera.
A mask must be worn during the student's stay in the Center. All instructions from the health authorities and the USC itself must be scrupulously followed, for the protection of the health of the Covid-19. Using a mask, applying a hydrogel or washing your hands with soap and water following the instructions and when possible increase the distance with the rest of the classmates and teacher in the classroom.
Contingency plan
METHODOLOGY
In relation to the development of remote teaching activities, they would be carried out, synchronously or asynchronously depending on what the center indicates, and always according to the schedule established by the center, through the Virtual Campus and Ms Teams.
Due to the nature and content of this subject, as well as the methodology used, the main difference between face-to-face teaching and remote teaching is the means through which the sessions and assessment activities are carried out.
To carry out tutorials, as well as to maintain direct communication both between the students themselves and between them and the teacher, they can be done through the Virtual Campus forum, through MS Teams or by email.
ASSESSMENT SYSTEM
The assessment system has no difference between the different scenarios, regardless of the type of teaching used (face-to-face or virtual), with the only difference that the evaluation activities will be carried out, as established by the competent authorities, or in person in the classroom or remotely through the telematic means available at the USC.
