A non-intrusive technique has been developed for measuring agglomeration rate constants (β0) in a constant shear field. A particulate suspension with a mean particle diameter, d, of about 10 μm is introduced in an optically accessible cylindrical Couette flow device. The suspension is illuminated by means of a pulsed laser and observed with a CCD camera. The recorded images are analysed off-lin...

*The views expressed here are those of the author and do not necessarily represent the views of the Federal Reserve Bank of Philadelphia or the Federal Reserve System. ensely populated areas tend to be more productive. Of course, the cost of living and producing in these locations is higher because congestion raises the cost of scarce fixed resources such as land. But despite the higher prices,...

Most studies about the effects of producers’ services on manufacturing agglomeration focus on the effects themselves while neglecting the mechanism that such effects spread. By stressing the key role of trade costs in the process of manufacturing agglomeration, this paper identifies a chain of effects from producers’ service improvements to manufacturing agglomeration via changing trade costs a...

In this article the concept of territorial agglomeration is discussed and reflected from the point of view of innovation activities. From this same angle, some suggestions are also made as to how to bring some clarity to the complex issue of the relationship between companies and their local operational environment. One of the conclusions is that a territorial agglomeration can be a basis for s...

Understanding and controlling powder de-agglomeration is of great importance in the development of dry powder inhaler (DPI) products. Dry dispersion laser diffraction measures particle size readily under controlled dispersing conditions, but has not been exploited fully to characterise inherent powder dispersibility. The aim of the study was to utilise particle size-dispersing pressure titratio...

With industrial integration accelerating in domestic and foreign enterprise, industrial integration is becoming the only way for regional development to break through its bottleneck. Compared with advanced foreign enterprises, there exists a significant gap in regional industrial integration, especially in the urban agglomeration of the energy chemical industries of Urumqi-Changji-Shihezi in Xi...

Bearing the responsibility of the rising strategy of central region of China, Changsha-Zhuzhou-Xiangtan Urban Agglomeration is an important growth pole of the development of the Yangtze river economic belt. Reasonable position of urban function in Changsha-Zhuzhou-Xiangtan Urban Agglomeration, is an inevitable requirement for the cooperative development of regional economy in Changsha, Zhuzhou ...

The agglomeration of innovation determinants has a significant influence on the innovation performance of industries and enterprises. Such an effect has received less attention in empirical research studies. This study involves a survey of the agglomeration effect of two important innovation determinants, R&D investment and R&D personnel, and its influence on innovation performance from the per...
