Physical and Rheological Properties of Biological Materials
Catalog Description:
Credits:3 Theory and use of physical and rheological properties of biological materials in agricultural and biological engineering applications
Pre-requisites/Co-requisites:
CHM 2045, MAC 2313 and PHY 2048
Course Objectives:
- Acquire the fundamental knowledge of physical and rheological properties that is needed for the engineering design, testing and analysis of systems, processes and components used in the processing, storage and handling of biological materials.
- Master technical writing skills by submitting weekly technical reports complete with summary, objectives, methodology, and presentation of results following rules of convention for tabular and graphical data presentation.
- Engage in team building and teamwork experiences through self-directed team formation and organization, with grades based on team output and teammate evaluation.
- Master the use of modern computational and experimental testing equipment such as, state-of-the-art universal testing machine, gas pycnometer, triaxial compression test, and computer data acquisition and analysis with spreadsheet software.

Academic Honesty :
All students admitted to the University of Florida have signed a statement of academic honesty committing themselves to be honest in all academic work and understanding that failure to comply with this commitment will result in disciplinary action. This statement is a reminder to uphold your obligation as a UF student and to be honest in all work submitted and exams taken in this course and all others.
Accommodation for Students with Disabilities
Students requesting classroom accommodation must first register with the Dean of Students Office. That office will provide the student with documentation that he/she must provide to the course instructor when requesting accommodation.
Use of Library, Personal References, PC Programs and Electronic Databases:
These items are university property and should be utilized with other users in mind. Never remove, mark, modify nor deface resources that do not belong to you. If you're in the habit of underlining text, do it only on your personal copy. It is inconsiderate, costly to others, and dishonest to use common references otherwise.
Software Use :
All faculty, staff and students of the University are required and expected to obey the laws and legal agreements governing software use. Failure to do so can lead to monetary damages and/or criminal penalties for the individual violator. Because such violations are also against University policies and rules, disciplinary action will be taken as appropriate. We, the members of the University of Florida community, pledge to hold ourselves and our peers to the highest standards of honesty and integrity.
UF Counseling Services :
| Resources are available on-campus for students having personal problems or lacking clear career and academic goals which interfere with their academic performance. These resources include: | |||||
