In addition, it is emphasised that effect mechanisms of biological harmful agents such as bacteria, fungi, insects, termites, marine organisms and, of non-biological harmful agents such as weathering, fire, hygroscopicity (movement) , chemicals, etc. Hence, key directions is to be explained keeping wood away from this kind of harmful agents and using it rantabl and economical. |
| Learning Outcomes | CTPO | TOA | | Upon successful completion of the course, the students will be able to : | | | | LO - 1 : | remember terminology of wood deterioration and wood microbiology; and, define biological and non-biological harmful agents | 1,2,5 | 1,6 | | LO - 2 : | differentiate the effect mechanism of biological and non-biological harmful agents | 1,2,5 | 1,6 | | LO - 3 : | identify biological harmful agents such as bacteria, fungi, insects, termites and marine borers, examinig both macroscopic and microscopic aspects | 1,2,5 | 1,6 | | LO - 4 : | put into practise the evidence based principles of wood deterioration to determine degradations in wood and, the principles of protection from biological and non-biological harmful agents in raw material storage area | 1,2,5 | 1 | | LO - 5 : | analyse understanding of which kind of wood-degrading agents available in different geographical regions of both the country and the world | 1,2,5 | 1,6 | | LO - 6 : | interrelate between wood-degrading agents and
ecological conditions
| 1,2,5 | 1 | | LO - 7 : | interpret the risk distribution of wood-degrading agents in both the country and the world | 1,2,5 | 1 | | CTPO : Contribution to programme outcomes, TOA :Type of assessment (1: written exam, 2: Oral exam, 3: Homework assignment, 4: Laboratory exercise/exam, 5: Seminar / presentation, 6: Term paper), LO : Learning Outcome | | |
| Wood microbiology: Bacteria, bacterial damage in wood, effect of bacterial damage on wood properties. Fungi, morphologic and physiological features of fungi, fungal ecology. Decay due to fungi. Macroscopic and microscopic features of white, brown and soft rots. Effect of decay on wood properties. Fungal and chemical stains. Sapstain and its effect on wood. Mold and its effect on wood. Classification of fungi. Recognition of some important fungi degrade softwoods and hardwoods. Fungi appear in miscellaneous wood raw materials after harvesting and possibilities preventing their damages. Animal harmful factors: morphologic and physiological features of insects, termites and marine borers. Ecology of animal harmful factors. Recognition of some important insects, termites and marine borers damage softwoods and hardwoods. Insects appear in miscellaneous wood raw materials after harvesting and possibilities preventing their damages. |
