Physico-chemical characteristics and market potential of sawdust charcoal briquette

Mitchual, S.J; Akowuah, J.O; Kemausuor1, F (Published in International Journal of Energy and Environmental Engineering, 2012)

In the absence of the widespread distribution of modern cooking fuels in developing countries, efforts are being made to utilise biomass residues which abound in most of these countries. This is intended to replace ...
Optimisation techniques for minimising saw teeth deflection and lumber thickness variation

Okai R.; Mitchual S.J.; Frimpong-Mensah K. (2006)

Lumber size control is an essential element in maximising yield and productivity because a small reduction in rough green target size could lead to substantial savings in wood fibre. One of the key components of rough green ...
Application of a novel technique for band sawing using a tip-inserted saw regarding surface profiles

Okai R.; Tanaka C.; Ohtani T.; Iwasaki Y. (2005)

One way of achieving a successful forest management leading to biodiversity conservation is to ensure that wood is processed in an efficient manner. The authors succeeded in developing a new technology for bandsawing using ...
Automatic determination of fiber orientation on OSB surface using line detection method based on small eigenvalue analysis

Hu C.; Tanaka C.; Okai R.; Ohtani T. (2005)

The modulus of rupture (MOR) which is the key to the strength of oriented strand board (OSB) depends on the fiber orientation on OSB surface. In order to improve the quality of OSB products, it is essential to optimize the ...
Influence of mechanical properties and mineral salts in wood species on tool wear of high-speed steels and stellite-tipped tools - Consideration of tool wear of the newly developed tip-inserted band saw

Okai R.; Tanaka C.; Iwasaki Y. (2006)

This paper is the third in a series of work done on a novel technique for bandsawing, which uses a tip-inserted saw, and is gaining increasing popularity in Japan. It builds up on previous reports on the novel technique ...
Technical expertise development in secondary technical schools: Effects of ICT-enhanced 4C/ID learning environments

Sarfo F.K.; Elen J. (2006)

This study assessed the effectiveness of powerful learning environments (PLE), developed in line with the specifications of the 4C/ID-model, and the additional effect of ICT for fostering the development of technical ...
Analysis of sawn lumber production from logging residues of branchwood of Aningeria robusta and Terminalia ivorensis

Okai R.; Boateng O. (2007)

One way of meeting the supply demands of the wood industry is through the reduction of waste in timber processing. It has been estimated in Ghana that for every tree felled, nearly 50% of the tree volume is left in the ...
Studies on reproducibility and accurate measurement of moisture content of wood samples using an electric moisture meter

Okai R. (2007)

Studies were conducted on reproducibility, and accurate measurement of moisture content of four wood samples using an electric moisture meter. Experimental results indicated that there was no clear relationship between ...
Influence of vibration coupling between bandsaw frame and feed-carriage system on sawdust spillage and surface quality of workpiece during sawing [Einfluss der Schwingungskopplung zwischen der Bands�ge und dem Vorschubwagen auf den Schnittverlust und die Oberfl�chenqualit�t des Schnittholzes]

Okai R. (2009)
