, 2014 This chapter discusses dispersive means of obtaining spectral resolution in spectrophotometry. These methods are used to spatially disperse or separate the various wavelengths of optical electromagnetic radiation to enable analysis of material properties in wavelength bandwidths that are appropriate to the material, the material property, and the ...

Dispersants in Stirred Ball Mill Grinding
KONA Powder and Particle Journal, 2014 The influence of chemical dispersants on the milling of dolomite was examined using a stirred ball mill. The effective degree of grinding was found to depend on the aggregation/dispersion state or the viscosity of ...

Recovery of oil spills by dispersants in marine arctic regions [PDF]
, 2010 The initial appearance of dispersants was 1960s and 1970s; oil spill dispersants have been the topic of significant research, testing, and debate. In spite of published reports about dispersant toxicity and effectiveness vary greatly, most spill response

CoRR, 2017 In the $k$-dispersion problem, we need to select $k$ nodes of a given graph so as to maximize the minimum distance between any two chosen nodes. This can be seen as a generalization of the independent set problem, where the goal is to select nodes so that the minimum distance is larger than 1.
