Context
The knowledge of consumer preferences in wood furniture is crucial for the wood processing industries.Aim
This study aims to identify the attributes of wood that affect the preferences of consumers from the city of Antananarivo, Madagascar, for wooden furnishings.Methods
Quantitative measurements of the density and aesthetic properties of 12 wood species were carried out. The properties measured were the colour in the CIEL*a*b* colour space, the texture through greyscale image processing, and the density. Then, the wood specimens were subjected to sensory analysis with 100 consumers.Results
The results showed that the "density" was a prime criterion in choosing a wood species. Concerning the visual aspect, Antananarivo consumers generally liked slightly dark wood colour (L* around 52), tending towards yellow, with a visible oriented texture. The influence of socio-economic factors was also highlighted.Conclusion
These results are of prime importance in the search for alternative species to replace precious woods that are becoming rare. 相似文献3.
Volatile organic contaminant (VOC) emissions from wastewater treatment plants may occur through a variety of mechanisms which mainly include volatilization, evaporation, biodegradation, and photodecomposition. A mathematical model incorporating the significant factors affecting VOC emissions from a secondary treatment facilities has been developed and verified with the operational data from wastewater treatment plant in south Florida. The model includes mass transfer considerations for volatilization from clarifier surfaces and weirs, in addition to volatilization from aeration basins. A simple model such as this one can be a useful tool to estimate VOC emissions from municipal wastewater treatment plants and to evaluate the present and future state of compliance with applicable air quality standards. 相似文献
