Noise is the insidious of all industrial pollutants, involving every industry and causing severe hearing loss in every country in the world. Exposure to excessive noise is the major avoidable cause of permanent hearing impairment. Worldwide, 16% of the disabling hearing loss in adults is attributed to occupational noise, ranging from 7 to 21% in the various subregions. The estimated cost of noi...

Aviation history provides an apt metaphor for the state of Rasch measurement practice, and its potential future. Flying was initially widely believed to be nothing but a spectacular and dangerous fad. Few saw in it any potential for the huge industry that it is today. The current state of Rasch measurement practice is quite akin to daredevil barnstorming in that the field is focused on isolated...

Correctly selecting a saw for a job is one of the most critical decisions a sawmiller has to make. Even after the selection is made, the saw must be set up and operated within certain specifications for balanced performance. An understanding of the interrelationship of raw materials, end products, machinery, and the sawing process itself is essential. Often sawmillers operate their saws with le...

In this work, we discuss and demonstrate the principle features of surface acoustic wave (SAW) aerosol generation, based on the properties of the fluid supply, the acoustic wave field and the acoustowetting phenomena. Furthermore, we demonstrate a compact SAW-based aerosol generator amenable to mass production fabricated using simple techniques including photolithography, computerized numerical...

Recent years saw the global wave of new low-carbon economy which is a strategic measure to cope with global warming, and it has gained concerns from many governments. As the representatives of developing countries, China is responsible for “common but distinguishing duty for global climate change.” Many policies have been made to develop low-carbon economy with the hope to advocate and innovate...
