a r t i c l e i n f o Keywords: Loose agglomerates Breakage Discrete element method Fine particles This paper presents a numerical study of the breakage of loose agglomerates based on the discrete element method. Agglomerates of fine mannitol particles were impacted with a target wall at different velocities and angles. It was observed that the agglomerates on impact experienced large plastic d...

The effect of nanoparticle structure on gas sensing performance is investigated. Size-selected nanostructured SnO2 agglomerate particles for gas sensors were made by scalable flame spray pyrolysis. These particles were polydisperse up to 12 m in diameter and consisted of primary particles of 10 nm in grain and crystal size as measured by transmission electron microscopy, x-ray diffraction, and ...

clustering technique is one of the most important techniques of data mining and is the branch of multivariate statistical analysis and a method for grouping similar data in to same clusters. with the databases getting bigger, the researchers try to find efficient and effective clustering methods so that they can make fast and real decisions. thus, in this paper, we proposed an improved ant syst...

The concept of home market effect (HME) refers to the phenomenon that firms agglomerate more than the market share in a large country. Krugman (1980) set up two models, showing that firms agglomerate more than the market share and that the wage is higher in the larger country. In Takahashi et al (2010), the equivalence between a larger firm share and a higher wage is proved. All of them are bas...

Blood-stage replication of the human malaria parasite Plasmodium falciparum occurs via schizogony, wherein daughter parasites are formed by a specialized cytokinesis known as segmentation. Here we identify a parasite protein, which we name P. falciparum Merozoite Organizing Protein (PfMOP), as essential for cytokinesis of blood-stage parasites. We show that, following PfMOP knockdown, parasites...

A crystal plasticity finite-element model, which explicitly and directly represents the complex microstructures of a non-metallic agglomerate inclusion within polycrystal nickel alloy, has been developed to study the mechanistic basis of fatigue crack nucleation. The methodology is to use the crystal plasticity model in conjunction with direct measurement at the microscale using high (angular) ...
