Symbiosis can be defined as a mutually beneficial relationship. Can there be a symbiotic relationship between forest products and the environment? If there is symbiosis of forest products and the environment, human beings are central to the process. Historically forests have always played a significant role in the human environment. At one end of the relationship, forests help provide the oxyge...

the quality of firms’ reaction against demand uncertainty affects the production inputs employment. in this research i have studied and compared the behavior of active firms in manufacturing sector with respect to the risk attitude and tested it’s effect on production inputs combination(with the special emphasize on labor employment). the research findings reveal that active firms in manufactur...

T field of forest products is a blend of several subjects—forestry, biology, chemistry, and engineering, among many others. This blending can at times lead to communication gaps between disciplines and create confusion for consumers. Inaccuracies can lead to the inappropriate utilization of wood, shortening its service life, or worse, creating safety hazards. It is therefore pertinent for users...

This study investigated the feasibility of using an electron beam (EB) process to cure chemically impregnated wood products. Maple wood planks were impregnated with the low-viscosity resins 1,6 hexanediol dimethacrylate (HDDA) and trimethylolpropane trimethacrylate (TMPTA). The addition of nanoparticles into the formulation was also studied. The impregnated wood was then cured by EB irradiation...

The industrial process adds to engineering wood products features absent in solid wood, with homogeneous structure and reduced defects, improved physical and mechanical properties, bio-deterioration, resistance and better dimensional stability, improving quality and increasing the reliability of structures wood. These features combined with using fast-growing trees, make them environmentally ec...

Chromated copper arsenate (CCA) treated wood has been most widely used in North America since the 1970s for many exterior applications such as decks, fences, playground equipment, utility poles, and others. A large volume of CCA-treated wood is currently coming out of service. Traditional disposal methods such as landfilling and incineration are not without adverse environmental outcomes. Recyc...

Evaluations of products based on visual stimuli are at the same time both subjective and important. The aim of this study was to examine the relationship between the visual properties of wood flooring and people’s reactions to computer visualization of interior wood products. The research strategy involved showing digital pictures of the same room, but with different wood floorings. The impress...

Adhesives products and demand for them in China are discussed in this paper with special emphasis on wood adhesives products in this decade. In 1994, the wood industries in China consumed more than 330,000 tons of adhesives. The estimated demand for wood adhesives will be more than 560,000 tons in the year 2000. The main wood adhesive used is urea-formaldehyde resin. Its consumption in 1994. wa...
