SYNOPSIS
This course deals with the micro- and macro-anatomy of wood
structure and its\r\noverall wood quality in terms of wood
chemistry, wood structure and formation,\r\nphysical and
mechanical properties of wood. Various industrial applications
of\r\nwood science concepts in wood processing, and wood
products, are described and\r\nillustrated, using examples from
Malaysian and overseas situations.
(Kursus ini menrangkumi mikro dan makro anatomi untuk
struktur kayu dan kualiti kayu secara keseluruhan dari segi
kimia kayu, struktur kayu dan formasi, sifat fisikal dan
mekanikal kayu.)
LEARNING
