As many larger secondary woodworking firms have moved production offshore and been adversely impacted by the recent housing downturn, smaller firms have become important to driving U.S. hardwood demand. This study compared and contrasted small and large firms on a number of factors to help determine the unique characteristics of small firms and to provide insights into useful areas for support. Small firms were found to be similar to large firms with respect to the perceived importance attributed to manufacturing capabilities as a business success factor. However, small firms differed substantially from large firms in other ways, such as less attention to information seeking and planned investments. Small firms also tended to make greater use of distribution yards in the hardwood lumber purchasing value chain and requested fewer services from their hardwood lumber suppliers than did larger firms. Small firms were found to be keen on developing their marketing capabilities, including e-commerce, to further their information exchange with customers to successfully produce made-to-order products. Small firms considered the individual characteristics of company owners/managers to be a relatively important success factor to business, more so than larger firms. The results are summarized and discussed through the lens of small firm reliance on niche markets for survival (including fully made-to-order production) and their need to find new revenue during economic downturns.

The wetting behavior of ring-shaped (or annular) surface domains is studied both experimentally and theoretically. The ring-shaped domains are lyophilic and embedded in a lyophobic substrate. Liquid droplets deposited on these domains can attain a variety of morphologies depending on the liquid volume and on the dimensions of the ringlike surface domains. In the experiments, the liquid volume is changed in a controlled manner by varying the temperature of the sample. Such a volume change leads to a characteristic sequence of droplet shapes and to morphological wetting transitions between these shapes. The experimental observations are in good agreement with analytical and numerical calculations based on the minimization of the interfacial free energy. Small droplets form ringlike liquid channels (or filaments) that are confined to the ring-shaped domains and do not spread onto the lyophobic disks enclosed by these rings. As one increases the volume of the droplets, one finds two different morphologies depending on the width of the ring-shaped domains. For narrow rings, the droplets form nonaxisymmetric liquid channels with a pronounced bulge. For broad rings, the droplets form axisymmetric caps that cover both the lyophilic rings and the lyophobic disks. © 2010 American Chemical Society.

The study evaluated the concentration and particle size distribution of air-borne wood dust in the Rubberwood furniture manufacturing industry. Air quality samples were measured at routing and hand-sanding work stations in furniture factories using the micro-orifice uniform deposit impactor (MOUDI) air-quality measuring instrument. It was found that less than 25% of the air-borne wood dust particles at the two work stations were less than 10 μm in size, which in turn did not pose major respiratory health hazards. However, the high wood dust concentrations at the two work stations is a matter of concern, and efforts must be taken to minimize the air-borne wood dust exposure levels workers are subjected to in the Rubberwood furniture manufacturing industry.

A study was carried out to evaluate the dust emission characteristics in the bamboo and rattan furniture manufacturing industries in Malaysia. It was found that the air-borne dust concentration increased in the order of rattan > bamboo > wood furniture manufacturing. Rattan also produced significantly higher amounts of finer dust than bamboo and wood, which can seriously affect the respiratory system of workers. Stricter dust control measures must be enforced in these industries. © 2015, Springer-Verlag Berlin Heidelberg.
