Learning Objectives

To give students the basic knowledge useful for a proper management and monitoring of working processes both in field and in agro-industrial plants. To promote the interest towards the technical-engineering aspects of the discipline, accustoming the students towards a critical evaluation of numerical data. To provide adequate emphasis to the aspects of personnel safety in workplaces. At the end of the course students will be able to evaluate some basic energy processes (energy from renewable sources, electricity, designing of pumping plants), favoring the technical-engineering approach. Furthermore, they will be able to identify the main sources of risk associated with the work activity and to evaluate them in accordance with the relevant legislation.

Course Structure

The teaching (6 CFU) includes 28 hours of lectures and 28 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.
