TECHNOLOGIES FOR INNOVATION AND SAFETY IN AGRICULTURE
Academic Year 2023/2024 - Teacher: Emanuele CERRUTOExpected Learning Outcomes
The aim of the course is to provide students with the basic knowledge necessary for a correct management and monitoring of work processes, also from an energy point of view, giving adequate emphasis to the aspects inherent to the safety of personnel in the workplace. At the end of the course the student will be able to evaluate some basic processes (plants for the production of energy from renewable sources, characteristics of electricity for its use in the agro-industrial sector, choice and sizing of pumps for use in agriculture ), favoring the technical-engineering approach. In addition, he will be able to identify the main sources of risk associated with the work activity (exposure to noise, exposure to vibrations, risks associated with the use of sprayers) and to evaluate them in accordance with current legislation.
Course Structure
The teaching (6 CFU) includes 21 hours of lectures and 42 hours of other activities, mainly guided numerical exercises for solving problems of practical interest for the profession of agronomist. PowerPoint presentations are mainly used to conduct lessons and Microsoft Excel to solve exercises. If teaching is given in a mixed formula or remotely, necessary changes may be introduced to what was previously stated in order to comply with the provided and reported syllabus. Learning assessment may also be carried out on line, should the conditions require it.
Information for students with disabilities and/or DSA
As a guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Integration - Services for Disabilities and/or DSAs), in the persons of professor Anna De Angelis.

Learning Assessment
Learning Assessment Procedures
During the course there will be two written tests lasting 2 hours reserved for attending students (attendance of at least 70%) and containing numerical exercises and open-ended questions. The final exam takes into account the results of the ongoing tests and usually consists of an oral interview. The result of the ongoing tests is valid only within the academic year in which it was completed. Verification of learning can also be carried out remotely, should the conditions require it.
The marks attributed will follow the following scheme, also on the basis of written tests:
Unsuitable
Knowledge and understanding of the topic: Important shortcomings. Significant inaccuracies.
Ability to analyze and synthesize: Irrelevant. Frequent generalizations. Inability to synthesize.
Use of references: Completely inappropriate.
