The development of glulam may give complementary, added-value to an important part of the timber production in the Congo Basin. Nevertheless, the high humidity in which these timbers operate may cause problems such as cracks and severe deformations i

Methane is the principal component of natural gas. In order to be liquefied, it is has to pass through a compression station where its’ temperature is lowered. An experimental investigation of the temperature drop behaviour of methane gas has been

The wood veneer dried artificially before gluing for the manufacture of plywood generally suffers several damages (cracks, deformations), decreasing the competitiveness of the process and limiting the use of nervous species of wood. The proposed solu

The forests of the Congo Basin constitute an essential treasure for the well-being of humanity. However, they are poorly managed because to the intensive and highly selective cutting of a limited number of species. The objective of this thesis is to
