| Requirements for awarding credit points | |
| Assessment of learning outcomes is done by evaluation of 2 parts:
1)elaborated and defended 7 laboratory works; 2)report on visits of Latvian timber industry companies. |
|
| Description of the organization and tasks of students’ independent work | |
| Students should learn following topics at their independent work:
•determination of wood shrinkage and swelling and wood density; •elaboration of wood drying schedules according 3 different technics; •determination of wood drying time according 2 different methods; •experimental drying of softwood and hardwood timber; •evaluation of drying quality (wood moisture measurements with different technics); •evaluation of drying quality (chase hardening and checking) •optimisation of drying schedules; •investigation of drying processes in Latvian timber industry companies. |
|
| Criteria for Evaluating Learning Outcomes | |
| •Laboratory works– 50% •Report of companies visits – 50%. | |
