Fluidized bed agglomeration is used to produce large and porous dry agglomerates with improved instant properties. Water (or binder solution) is sprayed in the fluidized bed of particles to render their surface sticky. The agglomerate growth results from the repetition of different steps (wetting of the particle surface, particles collision and bridging, and drying) and depends on the processin...

In recent years, there has been growing interest to use computational fluid dynamics (CFD) for exploring dropletparticles interaction under the turbulent flow of air inside spray dryer systems. The final goal is to predict the dried solid particle size and mass flux distributions under the conditions of collision, coalescence and agglomeration of the droplets and particles. The coarse-grained s...

Nanoparticles (NPs) of ZnO are reported to enhance plant growth; however, during NPs syntheses, they tend agglomerate, affecting their dispersion. Agglomeration can be counteracted if surface is modified and/or have the appropriate morphology. The objective present study was assess effects morphology, modification, and way application NPs-ZnO on tomato. Two morphologies (spherical or hexagonal)...

We consider the parallel developments in the economics of agglomeration and the economics of networks. We explore the complementarities between the productivity benefits of agglomeration and those of network linkages, arguing that networks of actors dispersed over space may substitute for agglomerations of actors at a single point. JEL classification: D20, L14, R30

Spherical silver nanoparticles were synthesized by the chemical condensation method using aloe vera or chamomile extracts as a reducing agent. Depending on type of and its concentration, size AgNpcs varied from 7 to 50 nm simply adjusting ratio starting reagents. These show properties due presence carbonyl compounds in their composition, particular organic acids. It is shown that regu­lation co...

The effects of inequality on economic growth depend on several factors. On one hand, they depend on the time horizon considered, on the initial level of income and on its initial distribution. But, on the other hand, as growth and inequality are also uneven across space, it also seems relevant to wonder about the effects of the geographic agglomeration of economic activity. Moreover, it seems r...

Purpose: This paper identifies those attributes of created and evolved retail agglomeration formats that have a substantial impact on overall attractiveness from the consumers' point of view. From an agglomeration management perspective primary areas of concern are identified and suggestions to increase the competitiveness of diverse agglomeration formats are presented. Design/methodology: Thro...

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,...
