Air classifier technology (ACT) is introduced as part of formulation integrated dry powder inhaler development (FIDPI) to optimise the de-agglomeration of inhalation powders. Carrier retention and de-agglomeration results obtained with a basic classifier concept are discussed. The theoretical cut-off diameter for lactose of the classifier used, is between 35 and 15 microm for flow rates ranging...

Under review for publication in the Journal of Urban Economics, September 2014 ABSTRACT: This paper develops a spatial general equilibrium model that accommodates both congestion and agglomeration externalities, while firms’ and households’ land-use decisions are endogenous across continuous space. Focusing on the interaction between externalities and land use patterns, we examine the efficienc...

Dear Sir,?At the present early stage of sero-diagnosis in typhoid fever perhaps this note may not be quite inopportune. Not having previously seen the method applied, I asked Dr. Srinivasa Rao, Bacteriologist to the Government of Mysore, to kindly give a demonstration in case I could find the necessary material. This Surgeon-Colonel Lang Browne very kindly supplied in the South Station Hospital...

In the last decade, dozens of local governments have enacted zoning ordinances designed to limit the concentration of payday lenders and other alternative financial services providers (AFSPs), such as check-cashing businesses and auto title loan shops, in their communities. The main impetus for these ordinances is to shield economically vulnerable residents from the industry's lending practices...

A multigrid procedure that makes use of coarse grids generated by the agglomeration of control volumes is advocated as a practical approach for solving the threedimensional Euler equations on unstructured grids about complex con gurations. It is shown that the agglomeration procedure can be tailored to achieve certain coarse grid properties such as the sizes of the coarse grids and aspect ratio...

Polyethylene (PE) and polypropylene (PP) make up for a large part of the total worldwide polymer production. Originally, both polymers were often produced in solution processes. However, fluidized bed reactors for polyethylene and polypropylene production gain increasing industrial interest because of the relatively low production costs, the ability to produce a wide range of polymer grades, an...

Agglomeration spill-over benefits are a major driver of policy creating industrial and science parks across the world. However, agglomeration benefits can be offset by competition arising out of the spatial proximity of firms. In this paper we examine the impact of agglomeration and selection on Taiwanese firms' total factor productivity (TFP) distribution and show that agglomeration causes the...
