convection in the biomass combustion chamber makes the most significant reduction in the products of incomplete combustion that degrades indoor air quality. Unfortunately, over half of the stove users live in areas with no electrical services that could be used to power a fan that requires as little as one watt of electrical power for operation. The purpose of the research we are reporting was to use a small amount of waste heat from such a stove to generate electricity "

HARMONICA-LIKE INSTRUMENTS IN ASIA

"Free reed instruments were widespread in Southeast and East Asia for long before the 'modern' Western free reed instruments, including the harmonica and the accordion-concertina 'squeezebox' family, were developed in Europe starting about two hundred years ago. In the last 20 years there has been considerable interest in the acoustics of free reed instruments, including the Asian free reed mouth organs. This paper deals with two of the very simplest instruments of this type: the enggung of Bali, a single free reed without pipe-resonator, and the free reed buffalo horn, in which a single free reed is mounted in the side of the animal horn."
